Description

TECHNICAL FIELD

The present invention related to a door with several improvements. For the sake of clarity the invention will be described in seven parts. Part A of the invention relates to an automatic mechanism for locking and opening of the door. Part B of the invention relates to a mechanism installed in the door lock that offers a variety of options to prevent locking of lock or to enable hermetic locking of door. Part C of the invention relates to a mechanism for sealing and stopping of the door, whereby the desired opening angle of the door, at which the stopping of door is desired, can be pre-set. Part D of the invention refers to the door handle mechanism. Part E of the invention relates to a safety lock designed for entrance doors. Part F of the invention relates to a concealed door hinge. Part G of the invention relates to a straight jamb for an entrance door.

BACKGROUND OF THE INVENTION

Regarding Part A of the Invention: Currently available door locks are based on a principle whereby the user inserts a key and turns it in the keyhole, and the key serves as a lever for activating the mechanism that locks or opens the bolts. The lock mechanism, subject of the present invention (hereinafter referred to as "the lock mechanism") differs from similar known devices both in the special and advanced structure of the mechanism itself and of its parts and in the results of its operation. Thus, for instance, the lock mechanism, subject of the present invention, enables automatic opening of the lock, whereby turning the key by as little as 10°-15° releases a safety catch and once the safety catch is released, the opening mechanism of the bolts functions automatically. In addition, when the bolts are inserted into the jamb and reach their end point within the jamb, they rotate by 90°, thus offering additional protection against break-in. In addition, the lock can be inserted into the body of the door from either the front or back of the door and not necessarily from the side of the door, thus leaving the frame of the door intact (except for holes required for the tongue and bolts), and without the long cutout in the side of the door through which the lock is customarily inserted into the body of the door, and which constitutes a point of weakness of the door, or in other words, a potential break-in point.

Regarding Part B of the Invention: The locks on most doors offer only a narrow range of options for locking or opening the lock. The present invention is a mechanism that is installed in the lock and which offers a variety of options, including the option of preventing the lock from locking or enabling hermetic locking of the door, and more.

Regarding Part C of the Invention: Most doors in buildings and houses, which are attached to the door jamb by hinges (as opposed to sliding doors), open to an angle of about 90°. It is customary to use mechanical means to position the stopping point of the door at the desired opening angle, and usually a rubber or wooden wedge is used, such that its pointed end is stuck into the gap between the door and the floor so as to stop the door at the desired opening angle. When it is desired that the door open at a maximal opening angle, and usually be up against the adjacent wall, it is customary to use a doorstop that comprises two parts: one is shaped like a cylinder and is permanently attached to the bottom part of the door, and the other is shaped like a recess that matches the cylinder and is permanently attached to the wall or floor at a point that corresponds with the attachment point of the cylinder to the door, such that upon contact between the two said parts, a connection is formed that fixes the door in place. In addition, most doors have a gap between the bottom of the door and the floor that enables penetration of dust and insects. In addition, the doorstop attachments interfere with the cleaning of the house and the installation of the doorstop requires drilling in the floor that may damage floor tiles, which, if broken, cannot always be easily replaced. The present invention is a mechanism that enables sealing of the door as well as stopping it at an opening angle that can be pre-set and changed from time to time.

Regarding Part D of the Invention: Fire door handles are customarily composed of a horizontal bar that spans across the width of the door and serves as a handle. When the handle is pushed towards the door, the door opens outward (such handles are customarily referred to as fire door push bars or emergency push bars). Emergency push bars are designed to enable the user to open the door by pushing the bar towards the door when the door is designed to open outward, and vice versa, and they are essential mainly in times of emergency and panic. Regular doors with standard handles, such as residential entrance doors, are opened by pushing the handle downward, a direction of action that is not very suitable in emergency situations. In addition, bar handles that extend the entire width of the door, such as those used on fire doors, are not used on residential doors for aesthetic reasons. The present invention solves both of these problems by presenting a mechanism that, on the one hand, is designed for use on a handle that looks like a regular, standard handle of a residential entrance door (as opposed to a fire door push bar) and, on the other hand, enables the user to open the door by pushing the handle outward (as opposed to downward) when the door opens outward (or by pulling the handle inward when the door opens inward). Thus, the handle functions also as an emergency door handle.

Regarding Part E of the Invention: Most entrance doors, particularly those of residential houses, are customarily equipped with safety locks that enable the door to open only to a small angle, and prevent opening the door wide and entering the house. Safety locks are currently available in a variety of shapes, such as the safety lock depicted in Drawing No. 1 or the well-known safety lock that is based on a metal chain, which is attached to the door jamb and which is inserted into a slot, which is attached to the door. One disadvantage of the currently existing safety locks lies in the fact that such locks is visible and are therefore aesthetically offensive, and in the fact that they protrude and sometimes physically injure the residents. The present invention is a safety lock that is concealed within the door and the door jamb. Regarding Part F of the Invention: Most doors are attached to the door jamb by one or more hinges. The common hinge comprises at least two parts, whereby one part is attached to the jamb and the other - to the door. The joining of the two above-mentioned parts of the hinge is usually based on the principle according to which a pin protruding from one part of the hinge fits inside a cylinder affixed to the other part of the hinges so as to enable the pin to pivot within the cylinder and thus enable the door to pivot relative to the jamb. Hinges commonly in use today protrude and are conspicuous, and are thus aesthetically offensive, particularly when used on entrance doors to homes or buildings. In addition, when the entrance door opens outward, the hinges are outwardly exposed and thus constitute a point of weakness in case of break-in. The present invention is a concealed door hinge, such that the hinge does not protrude and is not visible but rather is concealed and hidden within both the door and the door jamb. In addition, the concealed hinge, subject of the present invention, is constructed so that the door can be raised and lowered relative to the jamb.

Regarding Part G of the Invention: The jambs of most hinged entrance doors (as opposed to sliding doors) protrude relative to the door line. Drawing No. 1, for example, depicts a closed door (1) whose jamb (2) protrudes in relation to the door line. The contact point (3) between the door and the jamb, located on the outside of the building, serves burglars as a pressure point for displacing the door from its hinges and jamb. Burglars customarily use a metal rod in order to breach doors (usually a large screwdriver or crowbar). This is done by placing the end of the breaching rod at point (3) and using the jamb (due to its protrusion relative to the door line) as a leaning point to facilitate displacement of the door from its lock and jamb. Another well-known method of displacing a door using the said leaning point makes use of a jack. Thus, the protrusion of the jamb relative to the door line constitutes a point of weakness in the protection of the structure against break-in. The present invention is a straight jamb for entrance doors, such that the jamb does not protrude relative to the door line but rather constitutes a direct continuation of the door line (when closed), and thus deprives burglars of the said leaning point that they use when breaching the door.

THE INVENTION

Part A of the Invention:

Automatic Mechanism for Locking and Opening of Door

In this Sub-Chapter we will describe Part A of the Invention:

In summary, the present invention is a door lock that includes a mechanism that opens the locking automatically. The lock includes a pin that rotates upon turning of the key, whose motion causes the release of a safety catch, which in turn causes the main plate to move upward and thus the bolt moves from the jamb back into the lock. The main plate of the lock is pushed upward by force of a horizontal rod that is pushed toward the lock by force of a spring that is wound around it and which compresses due to pressure of the opposite jamb when the door is closed. The horizontal rod causes the plate to rise along with the bolt and thus returns the bolt from the jamb back into the lock. The lock includes the possibility that the bolt, when fully inserted into the jamb, rotates partially around its center axis and thus reinforces the locking in the body of the jamb. Use of the lock enables to use a door whose frame is intact expert for the holes required for the bolts and rods that come out of it and which does not have a cutout in its side through which, in regular doors, the lock is inserted into the door.

The present invention is a door lock mechanism. Drawing No. 1 depicts the door and the lock mechanism in open position, in other words, the bolts are in the lock rather than in the jamb and the door itself is open rather than shut.

Terminology: "Closed door" - "Opened door" - "Locked door" - "Unlocked door". In order to create fluency in the wording of the present patent application, the term "Closed door" will refer to the state in which the door is shut (closed), regardless of whether it is locked (i.e. bolts are in the jamb) or unlocked (bolts are in the lock). The term "Opened door" will refer to the state in which the door is not closed. The term "Locked door" will describe the state in which the bolts are bolted into the jamb; whereas the term "Unlocked door" will refer to the state in which the bolts are still in the lock. In addition, any time the directions "right" or "left" are mentioned, they will refer to the way the mechanism is depicted in the drawing.

The mechanism, as depicted in Drawing No. 1, comprises a main plate (1) that can move up and down. The plate (1) is made of metal or some other heavy material. The main plate descends by force of its own weight. When the main plate (1) is in "up" position, the door is unlocked, in other words, the bolts are in the lock. When the main plate (1) is in "down" position, the door is locked, in other words, the bolts are bolted into the jamb. When the door is shut (closed), the lock mechanism is activated automatically according to the following chain of actions and reactions: When the door is shut and is in closed position, the pin (2) is pushed to the right and into the lock due to its contact with the left-hand jamb. A small metal plate (3) is attached (and secured with a nut) to the inner end of pin (2), serving as a safety catch and preventing rod (4) from dropping. Rod (4) is permanently attached to the main plate (1). Rod (4) has a notch (41) in its bottom part, which leans on the safety catch (3), thus preventing rod (4) from dropping by force of its own weight and that of the main plate. When the pin (2) is pushed inward, the safety catch (3) is released from the notch (41), causing the rod (4) and the main plate (1) to drop due to their own weights.

The bottom part of the main plate (1) has one or more slots (5) (the drawing shows two slots) that serve as guides in which the bolts (6) slide from the lock into the jamb and back. The bolts (6) can move horizontally. When the main plate (1) moves from "up" to "down" position, it causes the bolts to move from the lock out into the jamb due to the movement of pin (61) that connects the bolt to the slot (5). In order to facilitate the movement of the bolts forward and backward, the bolts are positioned between two guides (62). Thus, when the door is closed, the lock automatically locks the door by inserting the bolts into the jamb. Drawing No. 2 depicts the lock mechanism in closed position (locked door), in other words, the main plate (1) is in "down" position, the bolts are in the jamb and the door is locked.

In order to open the door and release the lock, a key is used, whose function is to release the safety catch, thus causing a chain reaction that leads to the opening of the door, i.e. to a state in which the door is unlocked. Partial turning of the key in the keyhole by as little as 10°-15° leads to movement of plate (8) towards the jamb (to the left). When the plate (8) moves toward the jamb, protrusion (81), which is located on the bottom part of plate (8), causes slight rotation of lever (9), which is connected to the body of the lock by pin (91), which in turn serves as an axis for lever (9). When the left-hand side of lever (9) (as shown in the drawing) descends due to the leftward motion of protrusion (81) together with plate (8), then the right-hand side (92) of lever (9) rises and causes the plate (10) to rise as well. The upward movement of plate (10) following the swivel of lever (9) takes place because of pin (102), which is connected to plate (10) and is pushed upward by the end (92) of lever (9). Plate (10) serves as a safety catch by preventing the rotation of piece (11), as explained below. A protruding pin (101) located at the bottom of plate (10) is inserted into a notch (110) in the upper part of piece (11). When plate (10) rises together with pin (101), locking of notch (110) is released and piece (11) rotates around axis (111), which connects it to the body of the lock. As a result of the pushing force of horizontal rod (12), piece (11) rotates so that its bottom part moves to the left (as illustrated), towards the jamb. When piece (11) rotates, its lower left-hand corner, in the form of protrusion (112), pushes the main plate (1) upwards by means of pin (Al) until the main plate (1) is in its "up" position (in other words, the door is unlocked) whereby it is secured by protrusion (112), which pushes pin (Al) upward, as mentioned above. When the door is opened, pin (2) is pushed outward (to the left) from the side of the door and the safety catch (3) locks plate (4) so that the door is also unlocked. This locking, effected by pin (2) and safety catch (3), enables piece (11) to return to its place, as in the situation in which the door is locked. In other words, turning the key slightly causes the bolts to return back into the body of the lock and causes piece (11) to hold the main plate (1) in "up" position. Upon opening of the door, pin (2) and safety catch (3) hold the main plate in "up" position and enable piece (11) to return to its place, as mentioned. When piece (11) returns to its place, it is again locked by plate (10), which drops due to pressure exerted by spring (103), which pushes it downward. Drawing No. 3 depicts the state in which piece (11) causes the main plate (1) to rise due to the contact with pin (Al).

The movement of the pin (2) (to the left), out from the side of the door when it is opened, is caused by the compression force of spring (21).

The movement of rod (12) into the lock (to the left) is caused due to pressure exerted by rod (12), which is caused by force of the structure, as described below. Drawing No. 4 depicts the right-hand part of rod (12). The left-hand end of rod (12) is attached to piece (11) (not shown in Drawing No. 4) and its right-hand part is loosely inserted into a cap (121) that protrudes toward the (right-hand) jamb through a hole in the side of the door. When the door is closed, cap (121) is pushed into the door (to the left) and compresses the spring (122) (with a force of about 25 kg). The movement of cap (121) to the left when the door is closed, does not cause rod (12) to move since there is a gap between the right-hand end of rod (12) and the inner end point of cap (121), so that only when the door is closed and the cap is pushed all the way toward the door, does the inner end of cap (121) touch the end of rod (12). Spring (122) is compressed between the frame of the door and pin (123), which is attached to rod (12). As a result, a force [the compression force of spring (122)] acts through rod (12) on piece (11), and when the safety catch of piece (11) [at point (HO)] is released, rod (12) is pushed to the left and causes piece (11) to rotate, as described above. To complete the pictures, it should be mentioned that when rod (12) is pushed to the left, spring (124), which is wound around rod (12), is compressed between pin (123) and point (125), which is fixed to the door. Spring (124) is weaker than spring (122). When the door opens, spring (124) causes rod (12) to move to the right and causes piece (11) to rotate back. As a result, piece (11) no longer holds the main plate (1) in "up" position, although the main plate remains in "up" position because opening of the door activates the pin's (2) safety catch at point (3), as described above. Hence, opening of the door transfers the burden of holding the main plate (1) in "up" position from piece (11) to the safety catch (3) of pin (2).

Drawing No. 5 helps understand and clarify the way in which turning the key in the keyhole by only several degrees (10°-15°) causes the above-described chain reaction. The round piece (keyhole 7), into which the key is inserted, includes a protτuding pin (71). When piece (7) is turned slightly, pin (71) moves pin (82), which is connected to plate (8), to the left and causes it to move left and lever (9) to swivel, as explained above.

The main plate (1) has a protruding pin (Bl) whereby, when the bolt (6) is bolted into the jamb, pin (Bl) blocks the bolt (6) and prevents it from moving backward, thus reinforcing the locking, as depicted in Drawing No. 2.

The structure of the lock, subject of the present invention, causes the bolts (6) to turn by 90° upon reaching their end point within the jamb. Drawing No. 6 depicts the lock from the opposite side relative to the other drawings, i.e. the bolts in Drawing No. 6 move left into the jamb. Bolt (6) is depicted with the door in unlocked position (Drawing No. 6 shows two bolts; the jamb is not illustrated here). As mentioned, bolt (6) can move horizontally between the guides (62), while moving along slot (5) using pin (61). The main plate (1) has another slot (51) (one or more, according to the number of bolts), in which pin (63), which is attached to pin (6), can move. When the main plate (1) drops, the bolt (6) moves to the right, along slot (5) and penetrates the jamb. At the same time, pin (63) moves along slot (51) and when it reaches the upper end (510) of slot (51), pin (63) rotates downward and causes bolt (6) to rotate around its center-inner axis at a 90° angle. As a result of this rotation motion, pin (64), which protrudes at the end of pin (6) and which is shown in the drawing in vertical position, rotates together with the pin and becomes horizontal. Pin (64) provides additional locking and reinforces the locking of the lock. Obviously, the hole in the jamb into which the bolt penetrates is oval or round, with two notches (one at the top of the circle and the other on the bottom). The notches enable pin (6) to penetrate together with pin (64), and when it reaches the end point within the jamb, pin (6) rotates around its inner axis as mentioned, and pin (64) is locked into an internal notch in the jamb. We wish to stress the point that the fact that the pin 63 located relatively in distance from the end point within the jamb gives the pin 63 more power (momentum) to rotate more easily the pin 6 around its center-inner axis. In addition, the fact that the rotation around its center-inner axis of pin 6 caused by the clash of pin 63 with the end 510 causes to a immediate rotation rather than gradually.

Use of the mechanism, subject of the invention, enables to construct the frame of the door in an intact manner, with no cutout through which the lock is customarily inserted into the door. In other words, the lock can be inserted into the body of the door from the front or back of the door rather than through its side. As a result, the frame of the door is intact, with no cutout that exists in doors today, and which constitutes a point of weakness in the frame of the door and serves as a potential break-in point. The present invention therefore includes the frame of the door without the said cutout. The materials from which the components of the lock should be made are similar to materials used for the manufacture of existing locks.

Part B of the Invention:

Control Mechanism for Locking of Entrance Doors

In this Sub-Chapter we will describe Part B of the Invention:

In summary, the present invention is a mechanism installed in the lock of a door that offers a variety of option, including the option of preventing locking of the lock or enabling hermetic locking of the door. The mechanism comprises a rounded [nut-shaped] metal plate with three hole and two notches. The central hole in the metal plate constitutes the metal plate's axis and the part to which the door handle is attached. Around the circumference of the metal plate are a round hole, an oval hole, an oval notch and a large notch containing a smaller notch. The mechanism includes two pins, the upper pin and the lower pin, whose heads protrude from the lock (one pin is located above the door handle and the other beneath it). The pins can be inserted into the holes and/or notches in the metal plate or they can be pulled out, offering a variety of possible locking positions for the lock and door

The present invention is a mechanism (1) that is installed in a door lock and which offers a variety of options, including the option of preventing the lock from locking or enabling hermetic locking of the door.

The main part of the mechanism (1) includes a round (nut-shaped) metal plate (2) that has three hole and two notches, as depicted in Drawing No. 1. The door handle is connected to the central hole (3) of the metal plate (2), and also constitutes the axis of the metal piece (2). Moving the door handle up or down causes the metal plate (2) to pivot around the axis, which is also the central hole (3). The mechanism in fact consists of two identical metal plates (2) that are joined together by the door handle such that their holes and notches overlap.

The mechanism includes two pins, the upper pin (4) and the lower pin (5). The heads of the two pins (4,5) protrude from the lock and are located above and below the door handle axis, as depicted in the drawings.

Pushing in on the heads of each of the two pins causes the pins to be inserted deeper into the body of the lock (hereinafter referred to as the pins' "in" position), and pulling the pins out returns them to their previous positions (hereinafter referred to as the pins' "out" position). The pins can be inserted deeper by pushing the pins or alternately by turning them (in a screwing-like motion) and thus inserting them deeper into the body of the lock or returning them to their previous position.

The metal plate (2) has a round hole (6) and an oval hole (7). The metal plate (2) also has an oval notch (8) and a large notch (9). The large notch (9) contains also a smaller notch (91). All of the above are depicted in Drawing No. 1.

Drawing No. 2 depicts a door lock that includes the mechanism (1) whereby the lock is in open position (the bolts are in the lock rather than in the jamb - hereinafter referred to as "opened lock"). The two pins (4,5) shown in Drawing No. 2 are in "out" position. When the lock is open and the two pins are in "out" position, the mechanism (1) is, in fact, inactive and does not cause any change in the lock's regular states of operation. Drawing No. 3 depicts the door lock including the mechanism (1) whereby the lock is in "opened" position. In Drawing No. 3, the upper pin (4) is in "in" position" whereas the bottom pin (5) is in "out" position. When the lock is open and the upper pin (4) is "in" and the bottom pin (5) is "out", the tongue (10) of the lock can be moved (into the body of the lock) only with a key, and not by moving the door handle. This is because when the upper pin (4) is in "in" position, its end is in the small notch (91) and prevents the metal plate (2), and thus also the door handle itself, from turning clockwise, which is the direction the handle must be turned in order to insert the tongue (10). [Clarification: In order to retract the tongue back from the jamb into the body of the lock, the door handle must be lifted and not lowered as customary with other doors.]

Drawing No. 4 depicts the door lock including the mechanism (1) whereby the lock is in "opened" position. In Drawing No. 4, the upper pin (4) is in "out" position" whereas the bottom pin (5) is in "in" position. When the lock is open and the upper pin (4) is "out" and the bottom pin (5) is "in", the lock functions as follows:

Upon closing of the door, the automatic locking mechanism of the bolts is not activated. [The automatic locking mechanism of the lock is described in a separate patent application submitted with respect to the general operating mechanism of the lock and is attached to the present application as Appendix A.] This happens because the bottom pin (5) is in the oval hole (7) in such a way that counter clockwise pivoting of the metal plate (2) is prevented (as depicted in the drawing). Since the metal plate (2) cannot pivot in the said direction, the middle plate (12), whose downward motion causes the bolts to enter into the body of the jamb, cannot move either. This happens because a pin (11) [depicted in Drawings Nos. 5, 7 and 8] is attached to the middle plate and downward motion of which is restricted by the metal plate (2). The pin (11) is inserted into the oval notch (8) and when the metal plate (2) turns counterclockwise, the middle plate (12) is lowered and, as a result, locks the bolts. Nevertheless, the tongue (10) functions as usual and is inserted into the corresponding hole in the jamb, since the bottom pin is in the left-hand side of the oval hole (7), which enables the metal plate (2), and thus the door handle as well, to pivot clockwise in a partial and restricted manner that is sufficient to enable the tongue (10) to repeatedly go back and forth from the jamb into the body of the lock.

When the lock is in "opened" position and the two pins are in "in" position, in addition to the above-mentioned results that follow from the bottom pin being in "in" position, the tongue cannot be moved using the door handle, since the upper pin (4), which in "in" position and is in the small notch (91) (as depicted in Drawing No. 3), neutralizes the handle, as mentioned above. This enables control over the opening and closing of the door [by means of the tongue (10) alone] using a key or an external (electrical) mechanism. [It is noted that the tongue is also controlled by a parallel mechanism.]

Drawing No. 5 depicts a door lock that includes the mechanism (1) whereby the lock is in an locked position (bolts are in the jamb - hereinafter referred to as "locked lock"). The two pins (4,5) shown in Drawing No. 5 are in "out" position. When the lock is locked and the two pins are in "out" position, the mechanism (1) is, in fact, inactive and does not cause any change in the lock's regular states of operation.

Drawing No. 6 depicts the door lock including the mechanism (1) whereby the lock is in "locked" position. In Drawing No. 6, the upper pin (4) is in "out" position" whereas the bottom pin (5) is in "in" position. When the lock is open and the upper pin (4) is "out" and the bottom pin (5) is "in", the tongue (10) can be moved (into the body of the lock) by neither the door handle nor a key. In other words, the door is hermetically locked and it cannot be opened using the handle or a key. This happens because when the bottom pin (5) is in "in" position it is in the round hole (6) of the metal plate (2) such that the metal plate (2) it prevented of any pivoting movement, both clockwise and counterclockwise. When the lock is locked, the part of the metal plate that does not have a notch is positioned opposite the tongue (10), preventing the tongue (10) from entering the lock, so that even with a key it is impossible to insert the tongue (10) into the lock.

The advantage of the lock that includes the mechanism subject of the invention of the present application over other existing locks is manifested in the control the user has over locking or preventing the locking of the door, as described above.

Part C of the Invention:

Mechanism for Sealing and Stopping Door at Varied Opening Angles

In this Sub-Chapter we will describe Part C of the Invention:

In summary, the present invention is a mechanism that seals the gap between the door and the floor and enables to stop the door at a pre-set opening angle that can be changed by the user. The mechanism is based on the ability of the insert, which comprises the bottom part of the door, to move up and down. The mechanism includes two rods that are permanently attached to the insert and are inserted into the frame of the door. The mechanism includes a vertical rod that permanently connects the insert to a metal piece, which is connected to a horizontal rod that extends to the door jamb through a hole in the side of the door. A metal cable is attached to the door jamb, runs within the body of the door through a hole in the side of the door, to a pulley at the other end of the door and is attached to the top-most hole of the metal piece. The mechanism includes a screw that attaches the pulley to the door and enables to move the pulley forward and backward relative to the door width. The mechanism also includes a spring that is wound around the vertical rod and is compressed between a sleeve, which is attached to the body of the door, at the bottom, and a pin, which is attached to the vertical rod itself, at the top. When the insert descends, the spring is compressed and, as a result, pushes the vertical rod upward upon opening of the door.

The present invention is a mechanism that seals the gap between the door and the floor and enables to stop the door (1) at an opening angle that is pre-set and can be changed by the user. The mechanism comprises an insert (2), which in fact constitutes the bottom part of the door, or rather the bottom strip of the door. The insert is permanently attached to the door, such that the insert is able to move up and down. The shape of the insert profile (in other words, its shape as viewed from above) matches that of the door profile, since the insert in fact constitutes the bottom part of the door such that the door's profile and the profile of the insert are similar up to the point of identity. For effective implementation of the invention, an insert that is 2-10 cm wide be used, although the invention can also be implemented using a narrower or broader insert. The function of the mechanism, subject of the present invention, is based on the insert

(2) being in a high position so that there is only a small gap between its bottom part and the floor. Such a gap prevents friction between the insert and the floor and enables the door to move without friction with the floor. When the opening motion of the door begins, the insert begins to descend so that when the door reaches the desired opening angle, at which the user wants the door to stop, the insert reaches the floor and stops the door, sealing it as mentioned above.

The insert is attached to the door at three points, although the invention can also be implemented by attaching it at more or less attachment points. A rod-shaped metal plate (3) is attached to each end of the insert (21, 22), or more precisely, at a small distance before each end, parallel to the door (and door jamb). The plate is permanently attached to the insert and is fit and inserted into a hole or track (4) located inside the frame of the door. The function of the plates (3) is to guide the insert, to stabilize it and to prevent it from rotating relative to the door. The fact that the plates

(3) are not attached to the body of the door enables the insert to move up and down relative to the door. The tracks or holes (4) into which the plates are inserted are wider than the thickness of the plates (3) so as to enable the insert to align itself with the floor line even when it is not parallel to the door line. The fact that the plates (3) can slant to the right or left within the tracks or holes (4) enables the insert to be non- parallel to the door line, and thus the insert can align itself with the floor line in case the floor is not parallel to the bottom line of the door, in other words, when the floor is uneven/not level.

For the sake of clarification, the external panel (100), which covers the door, covers the entire door and most of the insert and only a narrow strip of the insert, about 3 cm wide, is visible at the bottom of the door. Thus, it is obvious that the gap between the insert and the door is not visible during use, and therefore there is no aesthetic or other flaw when the gap between the insert and the door is not uniform, as in the case of an uneven/non-level floor.

The insert is attached to the door by means of a vertical rod (5) that is permanently attached to the middle of the insert, although it could be attached to other parts of the insert as well. The vertical rod (5) is permanently attached also to a metal piece (6), which in the drawing is triangular in shape, although it could be any other shape as well (hereinafter referred to as "the triangle"). The triangle (6) has three apex points (61, 62, 63) (hereinafter referred to as "the apexes"). The triangle (6) is permanently attached (by a hinge) to the body of the door at apex (61). The vertical rod (5) is attached to the triangle at apex (62). In between apexes (61) and (63) is another attachment point (64) to which a horizontal rod (7) is attached. The horizontal rod (7) traverses the door and penetrates the left side of the door (as depicted in the drawing), reaching the door jamb at point (8). The structure includes the triangle (6), the rods (5, 7) and the attachment points of the rods to the triangle and the attachment point of the triangle to the door. Since these attachments are based on a hinge principle, when the horizontal rod (7) is pushed in toward the middle of the door, apex (62) descends and as a result pushes the vertical rod (5) downward. This mechanism converts horizontal motion into vertical motion.

When the door is closed, the horizontal rod (7) is pushed towards the triangle (6) since the horizontal rod's end is pressed against the jamb at point (8). When the door is closed, as mentioned, the horizontal rod (7) is pushed towards the triangle (6) and causes the triangle (6) to rotate around apex (61) (the triangle's axis point) so that apex (62) descends and the vertical rod (5) is pushed downward, causing the insert (2) to descend toward the floor. Hence, when the door is closed, the insert is in its down- most position and thus seals the gap between the floor and the door.

A spring (9) that is wound around the vertical rod (5) is compressed between a sleeve (10), which is permanently attached to the door, and a locking pin (11), which is permanently attached to the vertical rod (5). As a result, when the vertical rod (5) descends due to the horizontal rod's (7) movement toward the center of the door, the spring (9) is compressed and spring pressure is created between the sleeve (10) and the locking pin (11). When the door is opened, the spring (9) causes the vertical rod (5) to rise since the horizontal rod (7) can be pushed into the gap created between the door and the jamb at point (8). Hence, it is obvious that the mechanism functions in such a way that when the door closes, the insert descends and when the door opens, even slightly, the insert rises and enables frictionless movement of the door relative to the floor.

The sealing and stopping mechanism, subject of the present invention, includes a metal cable (12) that is attached at point (13) to the jamb (to which the hinged door is attached). The cable (12) stretches horizontally from point (13), around a pulley (14), which is attached to the other side of the door by means of a screw, to apex (63) on the triangle (6). When the door opens, the cable (12) is tensioned since the attachment point (13) [at which the cable (12) is attached to the jamb] remains fixed while the door, due to its pivoting motion relative to the jamb, in fact draws away. As a result (of the opening of the door), the cable (12) causes the triangle (6) to rotate since apex (63) is pulled upward due to the tensioning of the cable (12). Hence, the opening of the door, which causes the cable to tension, leads in turn to the descent of the insert and to the stopping of the door. The point at which the insert is pressed against the floor is determined by the initial tension of the cable (12). The more slack is the cable, the wider the angle the door must be opened to until it stops due to the descent of the insert onto the floor. Control over the slackness of the cable (12) is achieved using a screw (141) that penetrates into the pulley (14). Tightening or loosening of the screw (141) causes the pulley to move to the right or to the left, thus in effect controlling the degree of slackness of the cable (12) and as a result, controlling the opening angle of the door at which the insert will descend and the door will stop. It is emphasized that the slackness of the cable is such that the insert begins to descend only after the door is opened to an angle of about 40°.

With the objective of enhancing the efficiency of the sealing and stopping of the door, a rubber strip is inserted into the bottom of the insert, as depicted in Drawing No. 2. The rubber strip is not attached to the insert but rather is inserted into two recesses (16, 17) and is positioned in the insert so that it in fact is "floating" within the insert. The rubber strip (15) is relatively heavy so that it has a natural tendency to drop downwards. When the insert descends and contacts the floor, the rubber strip (15) aligns itself on the floor and since it is plastic and elastic, it provides good sealing of

the gap between the door and the floor even if the floor texture is not smooth or the floor is uneven/not level. The bottom part of the rubber strip (15) comprises two elements. One (18), which faces the interior of the house, is thick and relatively rigid and serves as a doorstop when it touches the floor, and the second (19) is thin and relatively flexible and provides more effective sealing against the penetration of dust and insects.

As mentioned above, the horizontal rod (7) ends at point (8) on the left-hand door jamb. The horizontal rod ends in what is a, preferably metal, cap or cup (81) with an internal thread, whereas the end of the horizontal rod itself has a corresponding external thread, such that the cap can turn on the rod and be used to shorten or lengthen the rod. An Allen wrench is used to turn the cap. When the horizontal rod (7) is shortened, point (64) on the triangle (6) moves to the right, causing apex (62) on the triangle to rise, which in turn raises the insert by means of the vertical rod (5), so that the insert's zero point rises. Changing the zero height of the insert can be effective in cases in which the user wishes to raise door, for instance, when new tiles are being applied to the floor (upon the existing tiles).

The advantage of the sealing and stopping mechanism, subject of the invention of the present application, over other currently known devices includes: (a) Sealing of the gap between the door and the floor, even in cases in which the floor is uneven/not level, (b) The door stops at a pre-set point that can be changed from time to time (by changing the zero height of the door and of the insert).

Part D of the Invention:

Handle Mechanism for Fire Door

In this Sub-Chapter we will describe Part D of the Invention: The present invention is implemented on a door that when slammed, causes the lock bolts to slide into the lintel and lock, and that is equipped with a knob that when turned, retracts the bolts from the lintel, enabling the door to open (hereinafter referred to as the "door"). The present invention refers to the handle mechanism of the said door.

The present invention refers to the handle mechanism of the door, whereby pulling the handle causes the bolt locking mechanism and the tongue to be retracted from the lintel, enabling the door to open. The present invention also refers to cases in which the door opens outward; in such cases pushing the handle outward causes the door to open. The explanations and drawings attached to the application refer to a door that opens inward and therefore the handle must be pulled inward, although the invention and application cover also the opposite case.

First, we present a general description of the door's locking mechanism prior to the addition of the mechanism, subject of the invention. Drawing No. 1 depicts the cover of the door's locking mechanism. A central, square axis (100) protrudes from the cover, to which the handle normally attaches, i.e. when the invention is not implemented. When the axis (100) is turned, the tongue is retracted into the door (like in any standard door). In addition, Drawing No. 1 depicts an axis (101) that when turned causes the bolts to be retracted from the lintel and the door to open. The axis (101) is designed to be attached to a

permanent key (since it is on the inside of the house). The knob that is attached to the axis (101) enables quick opening of the door, as explained above. When the axis (101) is turned, the pin (102) is moved to the right, thus releasing the bolts. [When the door is in normal position, i.e. when the present invention is not implemented, the pin (102) does not protrude from the lock mechanism's cover. Here, the pin (102) has been slightly extended outward for the purposes of implementing the invention, for reasons that will be presented later on in the description.]

The main components of the mechanism (1), subject of the invention, are: a main base (2), a "butterfly" device (3), a main lever (4), and a vertical lever (5).

The main base (2) is depicted in Drawing No. 2, which is identical to Drawing No. 1 but for the addition and installation of the main base (2) on the door lock cover plate. The main base (2) comprises two perpendicular, trapezoid "wings" (21) (22), whose long base is attached to the body of the lock and whose short side faces away from the door. Each trapezoid wing (21) (22) has a hole (210) (220) in its narrow, upper part.

Drawing No. 3 depicts the butterfly device (3), which has the general shape of a largely hollow elliptical cylinder with a center hole (31). The shape of the center hole (31) is identical or similar to that of the central shaft (100), since the butterfly device is designed to be inserted over the shaft in order to turn it. Drawing No. 4 is identical to Drawing No. 2 but for the addition of the butterfly device (3) and its insertion over the central shaft (100). The butterfly device (3) is inserted over the central shaft (100) in a loose manner, in other words it is not fixed in place. When the butterfly device (3) is turned, the central shaft (100) turns as well.

Drawing No. 5 depicts the main lever (4), which has the general shape of an elongated rectangular plate that is bent 90° into an L shape. The horizontal part (41) of the lever is rectangular and has a hole (42) designed to be inserted over a shaft (61) that is attached to the handle (6) of the door. The vertical part (43) of the lever (4) is also rectangular and has two short fingers (44) (45) that protrude from its inner face and which are parallel to the horizontal part (41) of the lever (4). Drawing No. 6 is identical to Drawing No. 2 but for the addition of the main lever (4) and its insertion over the shaft (61) that is attached to the handle (6). The main lever (4) is inserted over the butterfly device (3) so that when the main lever (4) is turned downward, the fingers (44) (45) cause the butterfly device (3) to turn for quick opening of the door.

Drawing No. 7 depicts the vertical lever (5), which is an elongated plate whose upper part is narrow and whose lower part has two indentations (51), as depicted in Drawing No. 7. The lever (5) also has a hole (52) that serves to attach the lever to the door lock cover plate, as described below. As mentioned, the vertical lever (5) is permanently attached to the door lock cover plate by a screw or pin that is inserted through the hole (52). The vertical lever (5) can, however, rotate about the hole (52) [on the pin or screw], which serves as a rotational axis for the vertical lever (5). Drawings 4 and 6 depict the place and manner in which the vertical lever (5) is installed. The indentations (51) in the vertical lever (5) are inserted over the butterfly device (3), as depicted in Drawing No. 4. When the butterfly turns, it causes the vertical lever (5) to rotate around the axis, i.e. the hole (52), so that the upper part of the vertical lever (5) rotates to the right. In released position, the upper part of the lever (5) barely touches the pin (102); when the vertical lever (5) is turned slightly, it moves the pin (102) to the right, thus releasing the bolts and opening the door.

The handle (6) is attached to the mechanism (1) as follows: The handle (6) has a small horizontal hole (62) at its base, as depicted in Drawing No. 9. The shaft (61) is inserted through the square hole (42) in the main lever (4), and it too has a small horizontal hole (64), as depicted in Drawing No. 6. The handle (6) is inserted over the shaft (61), as depicted in Drawing No. 8. A horizontal rod (63) is inserted through the holes (210) (220) in the perpendicular wings of the main base (2), the hole (64) in the shaft (61) and the hole (62) in the handle (6).

Thus, when the handle (6) is pulled upward, the main lever (4) rotates about the horizontal rod (63), which constitutes a pivot for the mechanism. When the main lever (4) rotates, it turns the butterfly device (3), which in turn causes two actions: First, it turns the center shaft (100) and retracts the tongue back from the lintel into the door; second, it turns the vertical lever (6) so that its upper part moves the pin (102) to the right, unlocking the bolts. Drawing No. 8 depicts the mechanism with the handle (6) in rest position and Drawing No. 9 depicts it in open position (the handle is pulled up/outward). Drawings Nos. 10 and 11 also depict the mechanism (1).

While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.

Part E of the Invention:

A Safety Lock for Entrance Doors that is Concealed in the Door

In this Sub-Chapter we will describe Part E of the Invention:

In summary, the present invention is a safety lock designed for entrance doors that is concealed within the door and door jamb when the door is closed. The safety lock comprises a rectangular metal plate with two slots, which is concealed in the door jamb, two metal pieces (or more) that are joined together at one end using a pin and are attached at the other end to the rectangular plate, and a pin that is concealed in the body of the door and can extend out from the body of the door toward the door jamb.

The present invention is a safety lock (1) designed for entrance doors that is concealed within the door and door jamb when the door is closed. The safety lock (1) enables the door to open only to a small angle but no farther. The safety lock (1) comprises three main parts as depicted in Drawings Nos. 2, 3 and 4. The first part is a plate (2) that is preferably rectangular and is made of metal or any other rigid material, as depicted in Drawing No. 2. The plate is positioned and concealed within the door jamb (the jamb that is adjacent to the door lock) (hereinafter referred to as "the door jamb"). The plate (2) includes two curved slots (3) as depicted in Drawing No. 2. The inner ends (31) of the slots almost touch each other and the outer ends (32) consist of round holes. There are one or more points (4) on the plate (preferably two points) at which the plate (2) is attached to the door jamb. The attachment points (4) include one or more cylinders (41), positioned on both sides of the plate (2), that create a space between each side of the plate (2) and the inner part of the door jamb where the plate (2) is concealed and attached.

As mentioned, the plate (2) is attached to the door jamb and is concealed within it. The plate (2) is attached to the door jamb opposite the top part of the door lock. The plate (2) is attached to the door jamb such that it is parallel to the side of the door, and such that the imaginary straight line that runs from point (21) to point (22) on the plate is perpendicular to the door when it is closed. Hence, one of the outer ends (32) of the two slots points up and the other points down and the near-contact point (31) of the two slots points in the direction in which the door opens. The plate (2) is attached to the body of the door jamb at the attachment points (4) using one screw or more.

The second part of the safety lock (1) comprises three identical pieces (5), made of metal or any other rigid material, as depicted in Drawing No. 3. The pieces each have a bay-like notch (54) and a hole (52) and a screw that attaches to the slot (3) in the plate (2). One piece is attached to the upper slot at point (52), the second piece is attached to the bottom slot at point (52), and the third piece is also attached to the upper slot at point (52) so as to reinforce the mechanism, as depicted, for instance, in Drawing No. 5. The three pieces (5) are joined together by a pin or screw at point (51). The attachment of the pieces (5) to the slots (3) at points (52), as described above, enables each of the pieces to move over the plate such that the pin or screw at point (52) moves back and forth along the slot between points (32) and (31).

When the mechanism is inserted in its entirety into the door jamb as depicted in Drawing No. 6, the pieces (5) are positioned so that point (52) on the piece (5) is positioned over point (32) on the plate (2) and point (51) at which the pieces (5) are joined is near points (31) [The pin (6) is not shown in this drawing].

The third part of the safety lock (1) includes a pin (6), depicted in Drawing No. 4, which is concealed in the door. The pin (6) is positioned within the door, parallel to the door bolts and is directed towards point (54) [the contact point of the notches in the pieces (5)]. In order to operate the safety lock, the key from the door's regular locking mechanism is turned [the key serves to lock the door (bolts) and to operate the safety lock - as depicted in Drawing and Appendix A), so that the pin extends out from the body of the door toward the door jamb, through a hole in the side of the door, into the door jamb, until the head (61) of the pin (6) reaches and is positioned at point (54). At this stage, when the door is opened, the pin (6) or more precisely the head (61) of the pin, drags the pieces (5) out, moving in the slots (3), until points (52) on the pieces (5) reach points (31) in the slots (3). The notches (54) in the pieces (5) fit around the notch (62) on the pin, in turn enabling the pin to effectively drag the pieces (5) outward. It should be mentioned that the pieces are locked around the head of the pin (on the notch at the head of the pin). Drawing No. 7 depicts the case in which the mechanism is fully open and activated [the pin (6) is not shown in the drawing]. It can be seen that due to the shape of the pieces (5), in all positions the notches (54) leave an open space that enables the pieces to move in the slots and also enable the pin (6), or more precisely the notch (62) of the pin, to be in the notch (54) until it locks around it, as mentioned, in open position. Drawing No. 8 depicts the case in which the mechanism is partially open and activated [the pin (6) is not shown in the drawing].

After the door is partially opened together with the mechanism (1), the door can of course be closed and the lock turned [moving the pin (6)] in order to return the pin (6) back into the door and thus enable regular opening of the door.

The advantage of the mechanism, subject of the invention of the present application, over other currently known means is manifested both in the fact that the mechanism is concealed in the door and door jamb and that it can be implemented also on doors that open outward.

Part F of the Invention;

Concealed Door Hinge

In this Sub-Chapter we will describe Part F of the Invention:

In summary, the present invention is a concealed door hinge composed of a flat metal plate with one hole or more, used to attach the hinge to the jamb using a screw. A curved arm, with a hole at the end, protrudes from the plate. The arm is curved; at its base, which is attached to the plate, the arm is wider and grows progressively narrower toward its end. The hinge is attached to the jamb such that the hinge plate is closely and parallelly affixed to the jamb. This is done using one screw, or more, which is screwed into the jamb, and can be secured using a nut. The screw in fact serves as a metal rod that extends from the door to the jamb, and thus constitutes as another bolt offering additional protection against break-in. The hinge is attached to the door by a pin or screw that is inserted through the hole in a corner of the door (as depicted in the overhead perspective of the door), enabling the door to pivot relative to the jamb while the hinge itself is always at rest.

The present invention is a door hinge (1), such that the hinge does not protrude and is not visible but rather is concealed and hidden within both the door (2) and the door jamb (3). Drawing No. 1 depicts the hinge (1). The hinge comprises a hinge plate (4), preferably flat, with one or more holes (5), by means of which the hinge (1) is attached to the jamb (3) using one or more screws (6) [the number of screws corresponds to the number of holes (5)]. An arched arm (7), with a hole (8) at its end, protrudes from the plate (4), preferably from the middle. The arm (7) is curved; at its base, which is attached to the plate (4), the arm is wider, and grows progressively narrower toward its end, as depicted in Drawing No. 1.

The hinge is attached to the jamb such that the hinge plate (4) is closely and parallelly affixed to the jamb using one or more screws (6). A nut (10) can be used to secure the end (9) of the screw (6) that is in the jamb. When the door is closed, the screw (6) also serves to reinforce the closing of the door against the jamb. This is possible since the end (9) of the screw (6) is recessed into the jamb whereas the other end (12) of the screw (6) is recessed into a recess (13) in the door. There is another hole (15) in the side of the door, directly opposite the hinge, that matches the arms cross-section and enables the hinge to recede into the door when the door is closed [in other words, the door moves toward the hinge and the jamb, and the hole (15) enables the door to close]. The screw (6) in fact serves as a metal rod that extends from the jamb to the door, and thus serves as another bolt offering additional protection against break-in. The hinge (1) is attached to the door (2) by a pin or screw that is inserted through the hole (8) in a corner of the door (as depicted in the overhead perspective of the door, Drawing No. 2), enabling the door to pivot relative to the jamb while the hinge itself is always at rest. The door is attached to the hinge by a screw (11) that is inserted through the hole (8) at the end of the arm (7).

The joining of the hinge (1) to the body of the door using the hole (8) in the arm, is executed using a pin or screw (11) that is attached to the body of the door, or possibly to a metal plate (14) that is attached to the door to which the screw (11) is attached when inserted through the hole (8). A disc made of a soft metal such as brass, should be placed between the metal plate and the arm (7) so as to enable minimal friction between arm and the said metal plate.

Joining of the hinge (1) to the jamb using the holes in the plate (4) can be executed by using a screw with nuts, as depicted in the drawings, or in any other acceptable way. Due to the fact that the hole(s) (5) in the hinge plate (4) are oval, the height at which the door is attached to the jamb can be adjusted. This is done by partially loosening the screws (6) and raising or lowering the door, to the extent permitted by the space between the screw (6) and the hole (5). The door is then positioned in relation to the jamb by tightening the screws (6) and fixing the door at the desired position relative to the jamb.

The hinge can be made of various materials, although it is recommended that it be made of the kind of metal conventionally used in this area. The hinge, subject of the invention in the present application, has several advantages over other hinges commonly in use today. First, the hinge is hidden and concealed within the bodies of the jamb and door and thus offers an aesthetic advantage over hinges that are exposed and visible. Second, the screws used to attach the hinge to the jamb serve as additional bolts that attach the door to the jamb when the door is closed, and in turn provide additional protection against break-in. In addition, when the entrance door opens outward, the fact that the hinges are concealed and hidden both in the door and in the jamb minimizes the points of weakness with respect to the possible breaching of the door. Finally, due to the oval shape of the holes in the hinge, used to attach the hinge to the jamb, the attachment point of the door can be raised or lowered relative to the jamb.

Part G of the Invention:

Straight Jamb for Entrance Door

In this Sub-Chapter we will describe Part G of the Invention:

In summary, the present invention is a straight jamb for entrance doors that does not protrude relative to the door line but rather constitutes a direct continuation of the door line when door is closed. The jamb is in fact a metal profile that can be made up of two integrated and joined profiles. One part is I _^ shaped whereas the second part is shaped like a square that is missing one side and whose other side extends outward in a straight line

The present invention is a smooth jamb (4) for entrance doors, such that the jamb does not protrude relative to the door line but rather constitutes a direct continuation of the door line, when door is closed. Drawing No. 2 shows the jamb (4) from above. The jamb (4) is actually a profile, made of metal or any other rigid material, that can be shaped as depicted (from above) in Drawing No. 3. In order to strengthen the jamb, it can and should be made up of two integrated profiles that are joined together, for instance, by welding. The cross-section of one part (6) is L-shaped, whereas the other part (5) of the jamb is shaped like a square that is missing one side and whose other side extends outward in a straight line, as depicted in the drawings.

Due to aesthetic considerations, it is customary that the jamb protrudes relative to the wall line, and therefore two decorative additions are attached to the jamb (4). The additions are made of soft materials such as aluminum or plastic and are attached, one (7) to the internal side of the jamb and the other (8) to the external side of the jamb.

The external contact point (3) between the jamb (4) and the door (1) when implementing the present invention and using the jamb (4), does not constitute a point of weakness, since when pressure or power is applied to point (3), the external decorative addition (8) might break or crush, but the jamb itself remains steadfast in its place.

The jamb is attached to the wall using the same means customarily used to attach jambs to walls.

The advantage of the jamb, subject of the invention of the present application, over jambs currently in use today is manifested both in the aspect of protection against break-in to the house, as explained above and in the aesthetic aspect, which stems from the fact that the external and internal additions can be in a variety of different colors (unlike jambs customarily in use today, that are supplied with the same color both on their internal and external sides).

THE DRAWINGS

The drawings attached to the present application are not intended to limit the scope of the invention and the possible ways of its application. The drawings are intended only to illustrate the invention and constitute only one of many possible ways of its application.

Drawings related Part A of the Invention:

Drawings Nos. 1, 2, 3, 5 and 7: These drawings depict the lock, subject of the invention, including its main components, which include a main plate (1) at the bottom of which is a slot (5) on which the bolts (6) move. The bolts (6) move between guides (62) on the slot (5) using pin (61) causing the main plate (1) to move up or down. The main plate (1) is attached to rod (4) which is locked at point (41) on safety catch (3) of rod (2). The lock also includes a keyhole (7) with surrounding round part which when turned, causes plate (8) to move, which in turn causes lever (9) to rotate so that its right-hand side rises and pushes plate (10) upward, releasing the safety catch at point (110), which in turn enables plate (11) to rotate due to the inward motion of rod (12).

Drawing No. 4: Drawing No. 4 depicts the right-hand side of rod (12), which is inserted into a cap (121). On the right-hand side of the rod, a spring (122) is compressed between the right-hand jamb and pin (123), which is attached to rod (12). In addition, ttieτe is another spring (124) on rod (12), which is compressed between pin (123) and the door at point (125). Drawing No. 6: Drawing No. 6 describes the way in which the bolt (6) rotates around its center axis upon reaching its end point within the jamb, when the door is locked. The bolt (6) includes a pin (63) that moves along slot (51) in the main plate (1) so that when it reaches the upper end (510) of the slot (51), the pin (63) rotates 90°, causing the bolt (6) to rotate as well. On the end of bolt (6) that is inserted into the jamb, is a pin (64), which serves to reinforce the locking of the bolt within the jamb.

Drawing No. 8: Drawing No. 8 presents a view of bolt (6) and all its components from the inside

Drawings Nos. 9 and 11: Drawings Nos. 9 and 11 present a view of the entire door from the inside, including the body of the lock and two additional sets of bolts (13). These sets function together with the bolts located in the body of the lock thanks to two rods (131) that connect them to the main plate (1).
