A MOVEMENT CONTROL MECHANISM Technical Field

The present invention relates to a movement control mechanism found especially in control panels of household appliances, automotive, furniture, electrical, electronics, watercraft, aircraft, and caravans and created to conceal and/or reveal the control buttons that enable the use of the home appliance according to the preferred purpose.

Prior Art Today, such appliances as cookers, washing machines and dishwashers used in houses and workplaces as auxiliary equipment comprise a control panel in order that user can monitor and control the functions. Such control panel comprises one or more buttons. These buttons are positioned on the spaces, preferably circular, arranged on the control panel and mounted in the shafts connected to the control card directly or by way of an intermediate piece. As the buttons are subject to rotating around their own axes, the shafts in connection with the buttons also move and allow the selection of functions based on the preferences of the user, which are arranged in a predetermined position, according to the request by the user.

Said control buttons disposed on the control panels of domestic appliances can, if desired, be concealed in the control panel and exposed from the panel again when needed for use. For example, a force parallel to the ground plane is applied on a button which is disposed in the control panel of a domestic appliance and currently concealed therein and thus it is released, thereby making said button protrude from the control panel. Afterwards, this button can be rotated around its own axis and the preferred adjustment can be made. The button, having completed its function, is introduced into/concealed in the control panel upon pushing the button again by applying a similar force parallel to the ground plane. In this case, said button remains concealed in the panel until next use and thus, not only an aesthetic appearance of the appliance for which it is used is provided but also the use of unwanted users, especially children is prevented.

Some of the control buttons in the state of the art do not have the aforementioned movement control mechanism and those having such mechanism cannot be brought to the same level as the control panel and they protrude from the control panel.

The International Patent Application No. W02016039705A1 / TR201410772 with the priority date 09.12.2014, claiming priority in Turkey, of the state of the art discloses a mechanism which comprises at least one hollow, cylindrical body which is introduced into the button which the user is in direct contact; at least one hollow cylindrical inner member which is mounted on the device that is calibrated and/or controlled, and on which the body is slid back and forth; at least one inner spring which enables the back and forth movement of the body on the inner member by introducing into the body, and which also limits this movement; at least one moving arm which enables the body to be locked on the inner member in back or forth movement, and which is aquaplaned on the inner surface of the body by being fixed on the inner member; and at least one fixing spring which is positioned on the inner surface of the inner member, and enables the inner member to hold onto the place where it is mounted tightly. In this prior art document, the movement is performed by means of five components. It is also disclosed in this document that the movement is stopped by means of a moving arm. However, such stopping operation is not detailed. Furthermore, the description discloses that the moving arm has a lock and the body is released from the lock of the moving arm and it moves away from the inner member with the help of the inner spring. Similarly, however, there is no teaching as to how said process is performed. In addition to these, it is described throughout the description that while the moving arm moves on the locking slide provided on the inner surface of the body along the body, it also compresses or loosens the inner spring. Such performance of the locking on the locking slide along the body causes the deformation of both the moving arm and the body and at the same time results in a very short service life of a concealable button mechanism. Therefore, it has been deemed necessary to provide a novel mechanism wherein there is no sliding on the body and the inner spring is not compressed or loosened by the moving arm. When this prior art document and the invention according to the present application are evaluated, it will be seen that the present invention also consists of five components similar to said prior art document. The most distinctive characteristic of the present invention from this prior art document is the way the position identifier (the component referred to as the moving arm in the prior art document) performs the locking process together with the barrier. In the novel design, there exists no locking slide and the inner spring is neither compressed nor loosened by the position identifier. In the novel design, however, said position identifier is generally made up of an orientating extension and a locking extension. Apart from this, the body is provided therein with a barrier and the position identifier and the barrier contact with one another in a way to limit the movement of the movable body. On the surface of the orientating extension facing the stationary body is an inclined surface. Thus, when the orientating extension disposed in the position identifier fits in the hole and contacts with the resilient element, a determined angle is formed between the central axis of the locking extension and the central axis of the stationary body. Therefore, the locking extension is slightly angled. This, in turn, enables the position identifier to readily move inside the barrier in cases when it is engaged with the barrier, and also to be readily displaced from the barrier.

The European Patent Application No. EP2550571B1 / TR201002246 with the priority date 03.24.2010, claiming priority in Turkey, of the state of the art discloses a push and pull mechanism which provides forward and backward movement of the control buttons of the appliances including control panels and which operates without constrain and in a balanced way. By means of the push and pull mechanism which is the subject of the invention, control buttons come out of the control panel during the use of appliance and enter into the control panel in out of use situations; the damage to control button is prevented during the transportation of the appliance in which it is used and it takes up less place. This invention comprises: at least one movable part which enables the push and pull mechanism to fasten to the button in the control panel of the appliance and which can move in forward and backward positions; at least one fixed part which is placed into the movable part and which enables it to be locked in forward and backward positions and to fasten to the element shaft that will be operated; at least one latch which is placed on the movable part and which enables the movable part to be locked and unlocked; and at least one flexible part which is placed on movable part and which enables latch to spring by applying force on the said latch and to be fixed in its place. In this invention, there exists a movable part which moves on the fixed part, and two latches and two flexible parts are disposed in order to stop this movement of said movable part and fixed part at certain positions. Forcing the movable part to move in one direction within the fixed part, on the other hand, is ensured by means of a spring. In this patent, a total of nine separate components are used, which, in turn, causes complexity in terms of components. The fact that said components operate in synchronization with one another and the excessive number of components cause problems in terms of costs in case of a breakdown, bringing about production and maintenance problems as well. In the present invention, however, a solution to the technical problem has been achieved by using four components, and thus efforts have been made to ensure that the components remain in the preferred positions.

And another document in the state of the art is the International Patent Application No. W09811574 / TR9600723 with the priority date 09.12.1996, claiming priority in Turkey, wherein a retractable rotary control knob used in all kinds of electrical household appliances, which protrudes from the control surface when pushed and which may be used for the operation of the components that are commanded by a turning or push-pull rod is disclosed. The fact that the cylindrical pin operating inside the mechanism movement space is produced as an integral part of the plastic structure used for the cap enables the realization of the control knob by using fewer components as compared with similar systems.

The movement control mechanism in the invention, which is the subject of the application, generally consists of a moving body, a stationary body, a barrier element, a first resilient element, a force divider, a second resilient element, a grip element, and a position identifier. The movable body is preferably mounted in the button and the stationary body is mounted in the shaft of the appliance to be operated. The movable body is capable of performing forward and backward movement along the stationary body. The barrier element is closed over the gap on the movable body. The position identifier, on the other hand, moves through the interval on the orienting block and the retaining block on the barrier element. Said movement is limited by way of the position identifier. During the opening and closing of the button by applying force, the force applied on the first resilient element can be divided and transferred to the second resilient element by means of the force divider between the first resilient element and the second resilient element. Thus, by dividing the force applied on the first resilient element and transferring it to the second resilient element, the second resilient element transmits the force to the position identifier, thereby restricting the movement of the position identifier by acting on the barrier element.

In the state of the art, there is no explanation regarding the technical features and the technical effects provided by the invention of the present application. In the present applications, a movement control mechanism which allows the control buttons to come out of the control panel during the use of the device and to enter into the control panel when not in use, enables the movement to be carried out without deviating or shifting from the center axes, locking without any skid, where compressing and loosening of the inner spring is not performed by any locking element, can be used as a child lock thanks to its concealable structure, which reduces the cost of packaging because the button does not stay 20-25 mm outside on the control panel, and takes up less space in container, lorry or truck loading during the transportation process, thus reducing the transportation cost, and by dividing the force exerted on the resilient elements (pedestrians) inside the button when the pressing force applied on it is heavy, allows the button to be opened and closed by moving in a single axis.

Objects of the Invention

The object of the present invention is to provide a movement control mechanism which enables the control buttons to be exposed out of the control panel during the use of the appliance and to remain inside the control panel when not in use.

Another object of the present invention is to provide a movement control mechanism in which the movement is performed without being offset or deviating from the central axes.

Another object of the present invention is to provide a movement control mechanism which is capable of locking without sliding.

Yet another object of the present invention is to provide a movement control mechanism in which compressing and loosening of the inner spring are not performed by any locking element.

Still another object of the present invention is to provide a movement control mechanism which may be used as a child safety mechanism thanks to the concealable nature thereof.

And another object of the present invention is to provide a movement control mechanism which reduces packaging costs thanks to the fact that the button does not protrude from the control panel 20-25 mm and which also reduces transportation costs by occupying less space in container, truck trailer or truck loadings during transportation.

Another purpose of the present invention is to realize a movement control mechanism that allows the button to open and close by moving in a single axis, by dividing the force exerted on the resilient elements (springs) therein when the pressing force applied on the button is heavy.

Another purpose of the present invention is to realize a movement control mechanism that prevents the wear of the position identifier inside the button by dividing the force exerted on the resilient elements (springs) therein when the pressing force applied on the button is heavy.

Brief Description of the Invention

A movement control mechanism realized to achieve the purpose of the present invention, defined in the first claim and other claims dependent on this claim generally consists of a moving body, a stationary body, a barrier element, a first resilient element, a force divider, a second resilient element, a grip element, and a position identifier. The movable body is preferably mounted in the button and the stationary body is mounted in the shaft of the appliance to be operated. The movable body is capable of performing forward and backward movement along the stationary body. The barrier element is closed over the gap on the movable body. The position identifier, on the other hand, moves through the interval on the orienting block and the retaining block on the barrier element. Said movement is limited by way of the position identifier. During the opening and closing of the button by applying force, the force applied on the first resilient element can be divided and transferred to the second resilient element by means of the force divider between the first resilient element and the second resilient element. Thus, by dividing the force applied on the first resilient element and transferring it to the second resilient element, the second resilient element transmits the force to the position identifier, thereby restricting the movement of the position identifier by acting on the barrier element.

A movement control mechanism (1) found especially in control panels of household appliances, automotive, furniture, electrical, electronics, watercraft, aircraft, and caravans and created to conceal and/or reveal the control buttons that enable the use of the home appliance according to the preferred purpose, in its most basic form, comprises: at least one movable body (2) mounted in the button and moving together with the button, at least one stationary body (3) which is mounted in the shaft of the appliance to be operated and made immobile and which guides the movement of the movable body (2) during the process in which the button is concealed or exposed, at least one barrier element (4) which is placed on the movable body (2), which can be mounted on the movable body (2) after the assembly of the movable body (2) and the fixed body (3), which ensures that the movement of the movable body (2) is restricted when it becomes in contact with the locator (9) mounted on the fixed body (3), at least one first resilient element (5) which is provided between the movable body (2) and the stationary body (3) and which, in case of the concealed position of the button, applies pushing force on the movable body (2), and thus forces the button to assume the released position, and located between the first resilient element (5) and the second resilient element

(7),

• fixed in contact with the stationary body (3) from its base,

• ensuring that the first resilient element (5), on which the pushing force is applied, transfers some of the pushing force to the stationary body (3) in case the button is in the concealed position,

• preventing the transfer of the said pushing force applied on the first resilient element (5) to the second resilient element (7),

• at least one force divider (6) providing the transfer of the remaining part of the pushing force to the second resilient element (7) of the first resilient element (5) on which the pushing force is applied, at least one second resilient element (7) located between the movable body (2) and the fixed body (3) in such a way that it contacts the position identifier (9), and transfers some of the pushing force it receives from the first resilient element (5) to the position identifier (9) and forces the button to its free position by applying the pushing force it receives from the first resilient element (5) to the movable body (2) in case the button is in the concealed position, at least one position identifier (9) which limits the movement of the movable body (2) in concealed position,

• which is in contact with the second resilient element (7) such that the second resilient element (7) will apply a pressure thereon and positioned in the stationary body (3) such that it will form an angle with the central axis of the stationary body (3),

• which is oriented according to the geometric structure of the barrier element (4) placed on the movable body (2) when the first pressure force is applied in order for the button in the free position to be concealed,

• which limits the movement of the movable body (2) by contacting with the barrier element (4) in a position in which the movable body (2) advances along the central axis of the stationary body (3),

• which is released from the barrier element (4) by returning to its angled position with respect to the central axis of the stationary body (3) when the second pressing force is applied, and enables the movable body (2) to return to the free position again.

A movement control mechanism (1) according to the present application found in control panels of household appliances, automotive, furniture, electrical, electronics, watercraft, aircraft, and caravans is created to conceal and/or reveal the control buttons that enable the use of the home appliance according to the preferred purpose. The movement control mechanism (1) ensures that the control buttons come out of the control panel during use of the device and enter into the control panel when not in use. The movement control mechanism (1) ensures that the movement is carried out without deviating or slipping from the central axes. The movement control mechanism (1) provides locking without any skid. The movement control mechanism (1) provides a system in which the compression and loosening of the inner spring is not performed by any locking element. The movement control mechanism (1) can be used as a child lock thanks to its concealable structure. The movement control mechanism (1) reduces the cost of transportation by taking up less space in the loading of containers, articulated trucks or trucks during the transportation process, which reduces the packaging cost due to the fact that the button does not remain 20-25 mm outside on the control panel. The movement control mechanism (1) ensures that the button is opened and closed by moving on a single axis by dividing the force on the springs inside when the pressing force applied on the button becomes heavy. The movement control mechanism (1) prevents the parts within the button from being worn out by dividing the force exerted on the springs therein due to the heavy pressing force applied on the button during opening and closing. The movement control mechanism (1) in an application of the invention generally comprises a movable body (2), a stationary body (3), a barrier element (4), a first resilient element (5), a force divider (6), a second resilient element (7), a retaining element (8) and a position identifier (9).

Throughout the description, the expression shaft of the appliance to be operated will be used to refer to the shaft which allows adjustment by pushing and/or rotating a component arranged in the control panel of any domestic appliance, said shaft being connected to the component. Said shaft of the appliance to be operated may for example be many different shafts including a shaft connected to the gas tap regulating gas flow in cooking appliances, a shaft connected to the program device controlling the program flow in washing machines, a shaft connected to the heat thermostat in appliances with thermostat, a shaft connected to the potentiometer in appliances with potentiometer, or the shafts of lighting switches used in houses and workplaces.

The term "released position" hereinafter used throughout the description means the unconcealed, i.e. exposed, position of the button while the "concealed position" means the concealed position of the button.

A movable body (2) in an embodiment of the invention is mounted on the button. The movable body (2) includes a main portion (2.1), a connection region (2.2), and an insertion clearance (2.3). Said main portion (2.1) and connection portion

(2.2) have a cylindrical geometry and a flat surface (2.1.2) exists at one side of the main portion (2.1). In addition to this, the main portion (2.1) and the connection portion (2.2) are hollow. The main portion (2.1) disposed in the movable body (2) constitutes the principal structure of the movable body (2). The connection portion

(2.2), on the other hand, constitutes the portion of the button which is mounted in the movable body (2). The main portion (2.1) arranged on the movable body (2) is provided thereon with one or more guide openings (2.1.1). Said guide openings (2.1.1) are made on the main portion (2.1) in order that the movable body (2) can move along the central axis of the stationary body (3) without any deviation. The guide opening (2.1.1) disposed in the main portion (2.1) is made through the whole length of the main portion (2.1) along the central axis of the movable body (2). Apart from the guide opening (2.1.1), the main portion (2.1) is also provided with a flat surface (2.1.2). Said flat surface (2.1.2) is formed so that the movable body (2) as well as the stationary body (3) will not rotate around their own axes. Also provided in the main portion (2.1) is a guide protrusion (2.1.3) so as to enable the movable body (2) to perform its unidirectional forward and backward movement in a perfect manner. The guide protrusion (2.1.3) is formed along the main portion (2.1) such that it will be parallel to the central axis of the movable body (2) in the inner portion of the main portion (2.1). Hence, no deviation occurs during the forward and backward movement of the movable body (2) along the central axis of the stationary body (3).

In an embodiment of the invention, the connection portion (2.2) arranged in the movable body (2), on the other hand, is the portion by which the movable body (2) is mounted in the button as explained above, wherein the area of said connection portion (2.2) contacting with the button is provided with a vertical seating groove (2.2.1) and a horizontal seating groove (2.2.2). Said vertical seating groove (2.2.1) and horizontal seating groove (2.2.2) are made in order to ensure that the button stably remains in its position subsequent to the mounting of said button. In this embodiment of the invention, the connection portion (2.2) is provided with one vertical seating groove (2.2.1) and more than one horizontal seating groove (2.2.2) which intersect said vertical seating groove (2.2.1) perpendicularly and which are disposed in parallel to the central axis of the movable body (2). In addition to the vertical seating groove (2.2.1) and the horizontal seating groove (2.2.2), there is also a resilient element protrusion (2.2.3) in the inner portion of the connection portion (2.2). Said first resilient element protrusion (2.2.3) is formed in the connection portion (2.2) in order to limit the movement of one end of the resilient element (5). The first resilient element (5) fits in said resilient element protrusion (2.2.3), and thus limiting the movement thereof within the connection portion (2.2).

In an embodiment of the invention, the insertion clearance (2.3) in the movable body (2) ensures that the barrier element (4) is placed and fixed on the movable body (2). The insertion clearance (2.3) includes a locking bearing (2.3.1), a seating channel (2.3.2) and a side contact surface (2.3.3). The barrier element (4) is fixed on the movable body (2) firstly by fitting the snap extensions (4.5) into the seating channel (2.3.2), and then, engaging the fixing tab (4.7) into the tab housing (2.3.1.4) in the locking bearing (2.3.1) such that the base seating extensions (4.1.1) will contact the side contact surfaces (2.3.3) of the insertion clearance (2.3) on the movable body (2).The seating channel (2.3.2) ensures that the barrier element (4) is placed in the insertion clearance (2.3) from the snap extensions (4.5). The snap extensions (4.5) engage the seating surface (2.3.2.2) by passing into the insertion clearance (2.3.2.1) of the seating channel (2.3.2). When the barrier element (4) is inserted from the snap extension (4.5) into the seating channel (2.3.2), the tab extension (4.6) is pressed against the locking bearing (2.3.1) by applying force. When the tab extension (4.6) is pressed against the locking bearing (2.3.1), the fixing tab (4.7) fits into the tab housing (2.3.1.2) so that the locking step (2.3.11.) passes into the tab seating clearance (4.7.1). When the barrier element (4), snap extension (4.5), and tab extension (4.6) are engaged to the seating channel (2.3.2) and the locking bearing (2.3.1), the base (4.1) contacts the side surfaces (2.3.3). A stationary body (3) found in an embodiment of the invention serves as a bearing for the movable body (2) and enables the movable body (2) to move in a given direction and in reverse direction thereto during the process in which the button switches from the released position to the concealed position and also during the process in which the button switches from the concealed position to the released position. Similar to the movable body (2), the stationary body (3) also consists of a seating portion (3.1) and a guide portion (3.2). The seating portion (3.1) disposed in the stationary body (3) preferably has a D-shaped geometry and is provided in the middle portion thereof with a resilient element clearance (3.1.1). A first resilient element (5), a force divider (6), and a second resilient element (7) which are provided between the movable body (2) and the stationary body (3) are introduced into said resilient element clearance (3.1.1). The seating portion (3.1) includes the resilient element clearance (3.1.1), the divider seating extension

(3.1.2) and the hole (3.1.3). The force divider (6) is placed on the divider base

(6.2) dividing the seating extension (3.1.2) of the seating portion (3.1) on the stationary body (3). The divider seating extension (3.1.2) is located at the part where the seating portion (3.1) contacts the orientating extension (9.1). The retaining element (8) is fixed at one end by passing it through the hole (3.1.3).

The guide portion (3.2) disposed in the stationary body (3) comprises a guide extension (3.2.1), a guide groove (3.2.2), a connection clearance (3.2.3), an extension clearance (3.2.4), a retaining block bearing (3.2.5) and also a retaining element clearance (3.2.3.1) and a retaining channel (3.2.3.2). The guide extension (3.2.1) disposed in the guide portion (3.2) is preferably formed at the side of the guide portion (3.2) close to the seating portion (3.1) and is preferably two in number. Said guide extensions (3.2.1) are fitted in the guide opening (2.1.1) provided in the movable body (2) and serve as a guide for the movable body (2) during the process in which the movable body (2) is slid on the stationary body (3), thereby preventing the movable body (2) from deviating from its route. The guide portion (3.2) is provided, in addition to the guide extension (3.2.1), with a guide groove (3.2.2). Said guide grooves (3.2.2), on the other hand, are made along the guide portion (3.2) such that they will be parallel to the central axis of the stationary body (3). The guide protrusion (2.1.3) disposed in the movable body (2) is fitted in the guide groove (3.2.2) and similarly, the guide groove

(3.2.2) and the guide protrusion (2.1.3) prevent the movable body (2) from deviating its route while it slides on the stationary body (3). Also provided in the guide portion (3.2) is a connection clearance (3.2.3). Said guide connection clearance (3.2.3) preferably has a D-shaped geometry and it is made such that it will be parallel to the central axis of the stationary body (3). The shaft of the appliance to be operated is placed in the connection clearance (3.2.3); thus, the stationary body (3) is fixed in the control panel. At one side of the connection clearance (3.2.3) is a retaining element clearance (3.2.3. l).The retaining element

(8) is placed in the retaining channel (3.2.3.2) of the retaining element clearance (3.2.3.1). Said extension clearance (3.2.4) supports that the position identifier (9) is in contact with the second resilient element (7) and that the position identifier

(9) stays in the preferred position. The orientating extension (9.1) disposed in the position identifier (9) is passed through the extension clearance (3.2.4). The retaining block bearing (3.2.5) is in a geometric form on which the retaining block

(4.3) would fit. When the barrier element (4) is placed in the insertion clearance

(2.3) in the movable body (2) and fixed therein, the retaining block (4.3) fits into the retaining block bearing (3.2.5) of the guide zone (3.2) of the stationary body (3).

The barrier element (4) in an embodiment of the invention is placed on the movable body (2). The barrier element (4) can be mounted on the movable body (2) after the movable body (2) and the stationary body (3) are assembled. When the barrier element (4) becomes in contact with the position identifier (9) mounted on the stationary body (3), it ensures that the movement of the movable body (2) is restricted. The barrier element (4) includes the base (4.1), the guiding barrier

(4.2), the restraining barrier (4.3), the gap (4.4), the snap extension (4.5), the tab extension (4.6) and the fixing tab (4.7). In the barrier element (4), the base (4.1), the snap extension (4.5), the tab extension (4.6) and the fixing tab (4.7) ensure that the barrier element (4) is fixed by inserting it into the insertion clearance (2.3) in the movable body (2). In the barrier element (4), the orienting block (4.2), the retaining block (4.3) and the interval (4.4) ensure the restriction of the movement of the movable body (2) when it becomes connected with the position identifier (9) mounted on the stationary body (3). The barrier element (4) is fixed on the movable body (2) firstly by fitting the snap extensions (4.5) into the seating channel (2.3.2), and then, engaging the fixing tab (4.7) into the tab housing (2.3.1.4) in the locking bearing (2.3.1) such that the base seating extensions (4.1.1) will contact the side contact surfaces (2.3.3) of the insertion clearance (2.3) on the movable body (2). When the barrier element (4) is placed in the insertion clearance (2.3) in the movable body (2) and fixed therein, the retaining block (4.3) fits into the retaining block bearing (3.2.5) of the guide zone (3.2) of the stationary body (3). When the barrier element (4) is placed on the movable body (2), its outer surface (4.1.3) contacts surface-to-surface with the outer surface of the movable body (2), and its inner surface (4.1.2) contacts surface-to-surface with the locking projection (9.3) and the support projection (9.4) of the position identifier (9).

When the barrier element (4) in an embodiment of the invention becomes in contact with the position identifier (6) mounted on the stationary body (3), it is inserted into the insertion clearance (2.3) in the movable body (2) in order to restrict the movement of the movable body (2). In the barrier element (4), the orienting block (4.2), the retaining block (4.3) and the interval (4.4) ensure the restriction of the movement of the movable body (2) when it becomes connected with the position identifier (9) mounted on the stationary body (3). The barrier element (4) has a movement-restricting design together with the orienting block (4.2), the retaining block (4.3) and the interval (4.4). There are more than one guiding surfaces (4.2.1) in the orienting block (4.2) located in the barrier element (4). In the barrier element (4), said orienting surfaces (4.2.1) are designed such that they will guide the movement of the position identifier (9) and positioned within the movable body (2) as such. In the barrier element (4), there is another retaining block (4.3) other than the orienting block (4.2). Said retaining block (4.3) comprises a guide surface (4.3.1) which guides the position identifier (9) while the movable body (2) proceeds from the released position to the concealed position; a retaining surface (4.3.2) and a seating surface (4.3.3) which serve as a bearing for the position identifier (9) during locking operation; and at the same time a rotating surface (4.3.4) which directs the position identifier (9) while the movable body (2) proceeds from the concealed position to the released position. In the barrier element (4), a clearance (4.4) is additionally formed between the orienting block (4.2) and the retaining block (4.3). The locking protrusion (9.3) disposed in the position identifier (9) advances in said interval (4.4).

In an embodiment of the invention, the barrier element (4) is fixed on the movable body (2) firstly by fitting the snap extensions (4.5) into the seating channel (2.3.2), and then, engaging the fixing tab (4.7) into the tab housing (2.3.1.4) in the locking bearing (2.3.1) such that the base seating extensions (4.1.1) will contact the side contact surfaces (2.3.3) of the insertion clearance (2.3) on the movable body (2). The seating channel (2.3.2) ensures that the barrier element (4) is placed in the insertion clearance (2.3) from the snap extensions (4.5). The snap extensions (4.5) engage the seating surface (2.3.2.2) by passing into the insertion clearance (2.3.2.1) of the seating channel (2.3.2). When the barrier element (4) is inserted from the snap extension (4.5) into the seating channel (2.3.2), the tab extension (4.6) is pressed against the locking bearing (2.3.1) by applying force. When the tab extension (4.6) is pressed against the locking bearing (2.3.1), the fixing tab (4.7) fits into the tab housing (2.3.1.2) so that the locking step (2.3.11.) passes into the tab seating clearance (4.7.1). When the barrier element (4), snap extension (4.5), and tab extension (4.6) are engaged to the seating channel (2.3.2) and the locking bearing (2.3.1), the base (4.1) contacts the side surfaces (2.3.3).

The first resilient element (5) in an embodiment of the invention is located between the movable body (2) and the stationary body (3). The first resilient element (5) forces the button to return to its free position by applying a pushing force to the movable body (2) in case the button is in the concealed position. The force divider (6) of an embodiment of the invention is found between the first resilient element (5) and the second resilient element (7). The force divider (6) is fixed in such a way that it contacts the stationary body (3) from its base. The force divider (6) ensures that the first resilient element (5), on which the pushing force is applied, transfers some of the pushing force to the stationary body (3) in case the button is in the concealed position. The force divider (6) prevents the transfer of the said pushing force applied on the first resilient element (5) to the second resilient element (7). The force divider (6) ensures that the remaining part of the pushing force applied on the first resilient element (5) is transferred to the second resilient element (7). The force divider (6) comprises the transmission body (6.1), the divider base (6.2) and the divider housing (6.3). The second resilient element (7) in an embodiment of the invention is located between the movable body (2) and the stationary body (3) in such a way that it contacts the position identifier (9). The second resilient element (7) transfers some of the pushing force it receives from the first resilient element (5) to the position identifier (9). The second resilient element (7) forces the button to its free position by applying the pushing force it receives from the first resilient element (5) to the movable body (2) when the button is in the concealed position. In order to form the movement control mechanism (1), the first resilient element (5) is passed through the resilient element cavity (3.1.1) located in the stationary body (3). Subsequently, the other end of the first resilient element (5), which is not inserted into the resilient element cavity (3.1.1), is placed on the resilient element projection (2.2.3) located in the movable body (2). A force divider (6) is placed on the end of the first resilient element (5), which is inserted into the resilient element cavity (3.1.1). The first resilient element (5) is inserted into the transmission body (6.1) of the force divider (6). The first resilient element (5) is passed to the force divider (6) in such a way that it contacts the contact surface (6.1.1) of the transmission body (6.1) in the force divider (6). The second resilient element (7) is placed in the divider housing (6.3) on the divider base (6.2) of the force divider (6). The force divider (6) is placed on the divider base (6.2) dividing the seating extension (3.1.2) of the seating portion (3.1) on the stationary body (3). After placing the position identifier (9), the barrier element (4), the first resilient element (5), the force divider (6) and the second resilient element (7), the movable body (2) is subjected to a force in a direction to compress the first resilient element (5) and the second resilient element (7) and in parallel to the central axis of the stationary body (3) and as a result of this preliminary force, the guide extension (3.2.1) disposed in the stationary body (3) is fitted in the guide opening (2.1.1) provided in the movable body (2), and the movement control mechanism (1) assumes the released position (D) in this case. In case a pressing force is applied on the button of the movement control mechanism (1), the movable body (2) moves along with the button in compression direction of the first resilient element (5) and the second resilient element (7) along the central axis of the stationary body (3) since the movable body (2) and the button are interconnected. During this movement, the barrier element (4) also advances towards the position identifier (9) together with the movable body (2). The force divider (6) prevents the pushing force generated by the first resilient element (5) from being transferred directly to the orientating extension (9.1) of the position identifier (9) when the button is pressed. The force divider (6), ensures that a portion of the pushing force of the first resilient element (5) placed on the contact surface (6.1.1) in the transmission body (6.1) is transferred to the stationary body (3) since the stationary body (3) from the divider base (6.2) is fitted on the divider seating extension (3.1.2) While a part of the pushing force of the first resilient element (5) is transferred to the stationary body (3), the other part ensures that it is transferred to the second resilient element (7) located in the divider housing (6.3). The second resilient element (7) transfers it to the orientating extension (9.1) of the position identifier (9) with which it is in contact, and thus provides the movement of the direction indicator extension (9.1) on the barrier element (4).

The retaining element (8) found in an embodiment of the present invention is placed in the retaining clearance (3.2.3.1) in the connection space (3.2.3) in such a way that it can be inserted into the retaining channel (3.2.3.2). The retaining element (8) is fixed at one end by passing it through the hole (3.1.3). The retaining element (8) preferably has a spring geometry and is of a flexible metal. The retaining element (8) is placed in the retaining element clearance (3.2.3.1) such that its elevated middle portion will face the side of the connection clearance (3.2.3), and being fitted therein. While the stationary body (3) is being placed in the connection clearance (3.2.3), the retaining element (8) slightly bends and applies a continuous friction force on the shaft of the appliance to be operated, whereby it prevents the stationary body (3) from being displaced from its position.

The position identifier (9) included in an embodiment of the invention, during the movement of the movable body (2) on the stationary body (3), controls this movement of the movable body (2) and stops it at preferred stages. The position identifier (9) typically consists of an orientating extension (9.1) and a locking extension (9.2). The orientating extension (9.1) located in the position identifier (9) is passed through the extension clearance (3.2.4).The orientating extension

(9.1) is in contact with the second resilient element (7) through its other edge. The second resilient element (7) is engaged with the orientating extension (9.1) through said edge and applies pressing force thereon. The orientating extension

(9.1) disposed in the position identifier (9) is provided with an inclined surface

(9.1.1). Said inclined surface (9.1.1) is arranged at the portion of the orientating extension (9.1) which contacts with the stationary body (3). In this case, the inclined surface (9.1.1) and the stationary body (3) is in surface-to-surface contact with one another when the second resilient element (7) contacts with the orientating extension (9.1) and applies pressure thereon. The angle of said inclined surface (9.1.1) with a proximate edge of the locking extension (9.2) is preferably ten degrees. In this case, a given angle is formed between the axis passing through the center of the locking extension (9.2) and the axis passing through the center of the stationary body (3) when the orientating extension (9.1) is passed through the extension clearance (3.2.4) and the inclined surface (9.1.1) and the stationary body (3) become in surface-to-surface contact with one another. In this embodiment of the invention, this angle which varies based on the angle of the inclined surface (9.1.1) is preferably ten degrees. The position identifier (9) is provided, apart from the orientating extension (9.1), with a locking extension

(9.2). The angle between the orientating extension (9.1) and the locking extension

(9.2) is preferably ninety degrees. The locking extension (9.2) extends along a certain distance, preferably at ninety degrees, starting from one end of the orientating extension (9.1). The opposite surface of the locking extension (9.2) which is devoid of the orientating extension (9.1) is provided with a locking protrusion (9.3) and a support protrusion (9.4). The central axis of the support protrusion (9.4) and the central axis of the orientating extension (9.1), both of which are disposed in the position identifier (9), coincide. The support protrusion (9.4) is slightly elevated from the related surface of the locking extension (9.2). The support protrusion (9.4) preferably has a circular form. The locking extension

(9.2) is provided, apart from the support protrusion (9.4), with a locking protrusion (9.3). Said locking protrusion (9.3), on the other hand, becomes in contact with the barrier element (4) and in this way prevents the movement of the movable body (2). The locking protrusion (9.3) in this embodiment of the invention preferably has a square geometry and it is located at the other end of the locking extension (9.2) which is devoid of the support protrusion (9.4); moreover, its height is the same as the support protrusion (9.4).

The assembly and operation of the movement control mechanism (1) in this application of the invention is carried out as follows. First of all, in order for the movable body (2), the stationary body (3), the barrier element (4), the first resilient element (5), the force divider (6), the second resilient element (7), the retaining element (8), and the position identifier (9) to form the movement control mechanism (1) as a whole, the first resilient element (5) is passed through the resilient element clearance (3.1.1) located in the stationary body (3). Subsequently, the other end of the first resilient element (5), which is not inserted into the resilient element cavity (3.1.1), is placed on the resilient element projection (2.2.3) located in the movable body (2). A force divider (6) is placed on the end of the first resilient element (5), which is inserted into the resilient element cavity (3.1.1). The first resilient element (5) is inserted into the transmission body (6.1) of the force divider (6). The first resilient element (5) is passed to the force divider (6) in such a way that it contacts the contact surface

(6.1.1) of the transmission body (6.1) in the force divider (6). The second resilient element (7) is placed in the divider housing (6.3) on the divider base (6.2) of the force divider (6). The force divider (6) is placed on the divider base (6.2) dividing the seating extension (3.1.2) of the seating portion (3.1) on the stationary body (3). After the position identifier (9) is mounted inside the movable body (2), the second resilient element (7) is placed in contact with the orientating extension

(9.1) from one end. In addition, the position identifier (9) is placed in the extension clearance (3.2.4) from the orientating extension (9.1). Finally, the barrier element (4) is placed in the insertion clearance (2.3) on the movable body (2). The barrier element (4) is fixed on the movable body (2) firstly by fitting the snap extensions (4.5) into the seating channel (2.3.2), and then, engaging the fixing tab (4.7) into the tab housing (2.3.1.4) in the locking bearing (2.3.1) such that the base seating extensions (4.1.1) will contact the side contact surfaces (2.3.3) of the insertion clearance (2.3) on the movable body (2). When the barrier element (4) is placed in the insertion clearance (2.3) in the movable body (2) and fixed therein, the retaining block (4.3) fits into the retaining block bearing (3.2.5) of the guide zone (3.2) of the stationary body (3).

After placing the position identifier (9), the barrier element (4), the first resilient element (5), the force divider (6) and the second resilient element (7), the movable body (2) is subjected to a force in a direction to compress the first resilient element (5) and the second resilient element (7) and in parallel to the central axis of the stationary body (3) and as a result of this preliminary force, the guide extension (3.2.1) disposed in the stationary body (3) is fitted in the guide opening

(2.1.1) provided in the movable body (2), and the movement control mechanism (1) assumes the released position (D) in this case. In continuation of embodying the movement control mechanism (1) as a whole, the shaft of the appliance to be operated is passed through the connection clearance (3.2.3) disposed in the stationary body (3), and thus achieving the connection of the movement control mechanism (1) to the control panel. Afterwards, the button is passed through the connection portion (2.2) of the movable body (2); thus, the button and the movement control mechanism (1) are interconnected. Henceforth, the movement control mechanism (1) becomes fully operational, being ready to switch from the released position to the concealed position, and from the concealed position to the released position. In case a pressing force is applied on the button when the movement control mechanism (1) is in this state, the movable body (2) moves along with the button in compression direction of the first resilient element (5) and the second resilient element (7) along the central axis of the stationary body (3) since the movable body (2) and the button are interconnected. During this movement, the barrier element (4) also advances towards the position identifier (9) together with the movable body (2). Henceforward, first the locking protrusion (9.3) contacts with the guide surface

(4.3.1) arranged in the retaining block (4.3) and rotates the position identifier (9) around the axis passing through the center of the orientating extension (9.1) based on the geometry of the guide surface (4.3.1) (Fig. 21). This movement continues until the end of the guide surface (4.3.1) (Fig. 22). Since an inclined surface (9.1.1) is provided in the orientating extension (9.1) at the end of the guide surface

(4.3.1), the position identifier (9) tends to rotate towards the interval (4.4), in which case the locking protrusion (9.3) advances in the interval (4.4) by following the orienting surface (4.2.1) and properly fits in the retaining surface (4.3.2) and the seating surface (4.3.3) (Fig. 20).

At this moment, the movable body (2) cannot move even if the pressing force applied on the button is removed due to the fact that the locking protrusion (9.3) which is disposed in the position identifier (9) is engaged in the retaining surface

(4.3.2) and the seating surface (4.3.3). This situation is defined as the switch from the free position to the concealed position. While the movable body (2) is in the concealed position in this way, there is only the pushing force exerted by the first resilient element (5) on the movable body (2). The pushing force exerted by the first resilient element (5) is directly transferred to the force divider (6). A part of the pushing force transferred from the first resilient element (5) to the force divider (6) is transferred to the divider seating extension (3.1.2) in the stationary body (3), with which the divider base (6.2) of the force divider (6) comes into contact, thus onto the stationary body (3). Thus, the remaining part of the pushing force applied by the first resilient element (5) is transferred to the second resilient element (7) and the wear of the orientating extension (9.1) is prevented.

The pushing force exerted by the second resilient element (7) is neutralized due to the locking protrusion (9.3) attached to the retaining block (4.3), and in this case, the movable body (2) cannot move. Henceforth, another pressing force is applied on the button when the button is preferred to be switched from the concealed position to the released position again. In this case, the locking protrusion (9.3) is first released from the retaining surface (4.3.2) and the seating surface (4.3.3), and thus the interval (4.4) becoming free. In the meantime, the position identifier (9) tends to rotate in the direction of the rotating surface (4.3.4) of the retaining block (4.3) due to the inclined surface (9.1.1) and moves through the interval (4.4), and after some time it is released from inside the interval (4.4).

The moment the locking protrusion (9.3) is released from the interval (4.4) is the maximum distance that the movable body (2) can move in the compression direction of the second resilient element (7) along the stationary body (3). In other words, the movable body (2) cannot move further on the stationary body (3). Henceforward, when the pressing force on the button is removed, the first resilient element (5) and the second resilient element (7) is activated and forces the movable body (2) to advance in the direction of the released position from the concealed position. Due to this strain of the second resilient element (7), the movable body (2) and thus the barrier element (4) also move in a similar direction and the locking projection (9.3) contacts the rotating surface (4.3.4). After some time, the engagement of the position identifier (9) with the barrier element (4) is terminated completely, and thereafter the movement of the movable body (2) continues until the stroke of the guide opening (2.1.1). In the latter case, the button assumes the released position again, leaving the concealed position.
