PADLOCKS

FIELD OF THE INVENTION The present invention relates to locking apparatus generally and more particularly to one or more hasps, shackles and padlocks used for locking one or more swinging or sliding doors, gates, blinds, or other objects.

BACKGROUND OF THE INVENTION Hasps and padlocks are used as locking solutions for fastening doors and similar objects, such as gates. Examples of objects that can be locked by such solutions include a door to a doorway, two swinging or sliding doors to each other, window blinds to the window frame, container doors to the container wall, and so forth. In these applications the hasp is implemented in sections. At least one section is mounted on each object to be locked. For example, one part of a hasp could be mounted on a door and the other part on the adjacent part of the doorway. Mounting means can be screws, rivets, welds, and other fastening methods. An example of a prior art hasp and padlock are shown in FIG. 1 and comprise first hasp section 20, second hasp section 22, shackle 24, lock 26, and mounting holes 28. Each hasp section has at least one channel through which a shackle can be passed. The shackle comprises depending legs, with each leg passing through a different hasp section and a lock attached to the ends of the legs to complete the locking of the objects. Prior art hasps are not appropriate for all needs, particularly applications where objects slide parallel to one another or swing adjacent to one another. It would be desirable to provide a hasp that can accommodate various applications involving objects that slide parallel, or swing adjacently, to one another. In addition to connecting a shackle and lock to an object, a hasp can also protect .the shackle and lock. Such protective hasps are comprised of sturdy material, such as stainless steel, and provide recesses in which most or all of the shackle and lock are protected by the hasp. FIG. 2A is an exploded view of a prior art protective hasp. FIG. 2B is an exploded view of a prior art protective hasp further illustrating a recess 30 for the hasp and a recess 32 for the lock. FIG. 2C is a view of a locked prior art protective hasp and padlock showing the recessed hasp 24 and padlock 26. An example of a prior art protective hasp as described above is disclosed in US patent no. 4,548,058, awarded to Bahry, et al, (1985) and entitled "Protective Hasps for a Padlock". Prior art protective hasps can be difficult to use. The design makes it difficult to insert and remove the shackle. Also trie shackle can be lost when not in use. Also, the lock can only be installed from the bottom. Also, only one lock can be used at a time. Also, the design of the mating shackle sections, while contributing to the vertical locking strength, does not contribute to the lateral locking strength. Also no means are provided for storing the lock when not in use. It would be desirable to provide a protective hasp where the shackle element is integrated into the hasp sections, lock, or both. This would eliminate problems related to inserting and removing the shackle and related to keeping track of the shackle when not in use. It would also be desirable to enable inserti on of the lock from another direction besides the bottom of the shackle secti ons or insertion of multiple locks. It would also be desirable for the mating surfaces of the shackle sections to contribute to the lateral locking strength. It would also be desirable to provide a protective hasp with storage means for storing the lock when not in use. Another problem with prior art hasps, shackles, and locks is that they are difficult to align for locking. It would also be desirable to provide a hasp, shackle, and lock that are easy to align for locking. Another problem with prior art hasps is that they require shackles and locks, both of which are difficult to apply and can be easily mislaid. It would therefore also be desirable to provide a hasp that also functions as" a lock, thereby removing the need for a separate lock and separate shackle. Other objects and advantages of the present invention will become apparent after reading the present specification and reviewing the accompanying drawings.

Hasp 21 (not shown) and lock 26 are similar to the embodiment of FIG. 26A with lock 26 further comprising an additional lock- engagement means 56, whereby the lock can prevent upward swinging motion of two second objects 112 (not shown), one by each lock-shackle pin 56. FIG. 24C is a top view of a lock with integrated shaped lock-shackle pins for locking swinging objects in accordance with an alternative embodiment of the present invention. Hasp 21 (not shown) and lock 26 are similar to the embodiment of FIG. 26B with lock-engagement means 56A having a shaped head 120, an example of the hea d shape being an elongation perpendicular to pin stem 122. Second objects 112 (not shown) include head sockets shaped to receive heads 120, thereby improving the fit of lock-engagement means 56A to the second object surface. FIG. 24D is a bottom view of a lock with integ rated shaped lock- shackle pins for locking swinging objects in accordance with an alternative embodiment of the present invention. Hasp 21 (not shown) and lock 26 are similar to the embodiment of FIG. 26C with lock-shackle pins 56A included on each of the four sides of lock 26, whereby the lock can prevent upward swinging motion of four second objects 112 (not shown) , one by each lock- engagement means 56A. FIG. 25A is a side section view and FIG. 25B is a front section view of a protective, hasp with integrated shackle pins in accordance with an alternative embodiment of the present invention. Hasp 21 comprises a protective shell 126 encasing shackle pins 40 to form a reinforced lock recess 32 that protects lock 26 when the lock is in use. Protective shell 126 can be implemented as covering one, two, three, or all four sides of lock. FIG. 26 is an elevation view of a protective hasp in accordance with an alternative embodiment of the present invention. Hasp sections 20 and 22 are provided with rounded upper sections 2OA and 2ZA, thereby making them easier to hold and align as well as more pleasing aesthetically. FIG. 27 is a section view of a protective hasp with interlocking abutting walls in accordance with an alternative embodiment of the present invention. The vertical abutting walls of hasp sections 20 and 22 are provided with interlocking profiles 82 and 84 respectively. The principle of this design is presented in more simpl e form in FIG. 28, which is an elevation view of a protective hasp with interlocking abutting walls in accordance with an alternative embodiment of the present invention. Hasp sections 20 and 22 comprise abutment surfaces 82 and 84 respectively. Abutment surfaces 82 and 84 are characterized in that there is at least one male projection 132 in one of the abutment surfaces with a complementary female recess 130 in the other abutment surface such that the male projection 132 can be slid into the female recess 130 by aligning one hasp section behind the other such that the contour of each male projection 132 is aligned with the inner perimeter of each complementary female recess 130. At that point, the rear hasp section can be brought forward until the two hasp sections are coplanar, thereby intertwining and grip ping the hasp sections along abutment surfaces 82 and 84. This creates a fixed connection (locks) the hasp sections along the two coplanar dimensions (laterally). In the embodiment shown in FIG. 28, male projection 132 is a wedge shaped extension while female recess 130 is a wedge shaped recess. This innovative connection has at least two advantages: it makes it easier to aligji the two hasp sections, even allowing the use of just one hand for this purpose, and it makes it possible to integrate a simple locking element in the hasp sections, thereby eliminating the need for a shackle or for a lock. FIG. 29A is an elevation view of a protective hasp with integrated lock in accordance with an alternative embodiment of the present invention. The embodiment utilizes the wedge-toothed abutting walls described earlier, thereby achieving coplanar locking of the hasp sections. Locking in the third dimension (perpendicular to the plane of the hasp sections) is easily accomplished with many types of simple locking means. For example, in the Figure, integrated lock 144 comprises basic key-operated cylinder 140, which turns tongue 142 from a stored position (shown with dashed line) to an engaged (locking) position in which the tongue extends into tongue recess 138 or the adjacent hasp section 22. It will clear to one s killed in the art that the locking mechanism can be located in either hasp secti on or spread across both of the them and that many locking means can be used. FIG. 29B is an elevation view of the embodi ment of FIG. 29A protective hasp, illustrating the two hasp sections locked together. FIG. 3OA is an elevation view of a protective hasp with interlocking abutting walls in accordance with an alternative embodiment of the present invention. In this embodiment the profile of along abutm ent surfaces 82 and 84 comprise parallelogram-shaped pairs of male projections 132 and complementary female recesses 130. FIG. 3OB is an elevation view of a protective hasp with interlocking abutting walls in accordance with an alternative embodiment of the present invention. In this embodiment the profiles of male projections 132 along abutment surface 84 comprise parallelograms that are inverted relative to one another. FIG. 31A and FIG. 31B are elevation views of a protective hasp with interlocking abutting walls in accordance with an alterna tive embodiment of the present invention. In this embodiment the profiles of male projections 132 along abutment surfaces 82 and 84 comprise convex shapes, such as circles (FIG. 31A) and ellipses (FIG. 31B). FIG. 32 is an elevation view of a protective hasp with interlocking abutting walls with projections in accordance with an alte rnative embodiment of the present invention. In this embodiment each hasp s ection has a hooked projection, here right-angled (but other configurations are also possible) that intertwines with a matching hooked projection on the oth er hasp section. the profiles of male projections 132 comprise projections along one common corner of abutment surfaces 82 and 84. FIG. 33A is an elevation view, and FIG. 33B is a cross-section view along the line delineated (A-A) in FIG. 33A of a protective hasp with interlocking abutting walls with unequal projections in the form of round pins, in accordance with an alternative embodiment of the present invention. This embodiment allows greater lateral freedom in the process of engaging both hasp sections. The profiles of the male projections 132 comprise substantially perpendicular projections along one common corner of abutment surfaces 82 and 84, with matching cavities on the other hasp section. Another advantage of this embodiment is the prevention of relative motion also in the up-down direction between the hasp sections when engaged.
