Description

Ejector Units and Push Units {EJECTOR UNIT AND PUSH DEVICE}

The present invention relates to an ejector device for particularly movable furniture parts, and in particular a push device for furniture or household goods, comprising at least one pivotably mounted lever preloaded by a spring in the discharge direction.

DE 20 2006 020 236 discloses a device for opening and closing movable furniture parts in which a locking unit is provided with two or more locking elements connected to each other simultaneously and substantially in a play-free manner. . One of the locking elements includes locking mechanisms such that the furniture part can be unlocked by indentation and sequential release in the open direction. Such a device is arranged in a relatively complex manner by a large number of individual components and requires a large installation space due to the two separate locking elements.

It is therefore an object of the present invention to provide an ejector device for movable parts which is arranged in a concise manner and which enables user friendly handling with respect to the push device.

This object is achieved by an ejector device having the features of claim 1 and a push device having the features of claim 13.

According to the invention, a latching mechanism is arranged on the lever, whereby the lever can be latched in the closed position against the force of the spring. Therefore, after the components are unlocked, they can be released in one open direction and the lever can be latched back again by the components in the closed position. As a result, the ejector device can be provided with a particularly concise configuration and can be arranged independently of any further guide elements, auto-shrink unit or dampers. Ejector devices arranged in this way can be used for particularly movable furniture parts such as drawers, sliding doors or flaps.

Preferably, the latching mechanism comprises a curved guide having a loop-shaped section in which the latching recess is arranged. A control element can be mounted on the lever, the control element being guided into the curve guide. The control element may comprise one or more pins coupled within the curved guide and displaceably mounted on the lever. In this respect, the control element can be arranged as a rod engaging through a long hole in the lever, so that the pin protrudes on opposite sides of the lever, each held in a curved guide. This allows for a particularly stable latching of the lever. Guide bevels can be arranged adjacent to the latching recesses for unlocking, whereby the rod can be displaced relative to the lever when the lever is pivoted so that unlocking occurs in a simple manner and for the unlocking process Only a short distance is required.

Preferably, the lever is rotatably mounted on the housing on which the curved guide is arranged. The housing may comprise two side walls each having a groove-shaped curved guide in the inner sides, the control element being guided therein. As a result, the curved guide and the control element are arranged in a protective manner in the housing and the lever. It is also clearly possible to arrange a curved guide on the lever and to provide a control element, ie a displaceable pin, on the housing.

According to one embodiment, the ejector device comprises several levers which are connected to one another and can move together via a connecting element. In particular when using an ejector device on the rear wall of the drawer, it may be necessary to provide several ejector devices distributed over the width of the drawer. Thus, individual triggering of the ejector device is prevented because the ejector devices are moved together through the connecting element.

The ejector device further comprises one or more pull out guides in which the push elements are displaceably held. The ejector device may be mounted on a push element, where the housing of the ejector device is optionally mounted to a stationary component, such as a furniture body or a push element. The push element can then be moved in the closing direction to unlock the lever, such that the lever is moved against the force of the spring and unlocked.

In a further variant, a magnet is provided on the lever, whereby the control element can be affected. The control element is preferably made of metal, thereby allowing the magnet to act with the control element at certain positions of the curved guide, especially in branch off areas where the control element can be displaced in the error direction without the action of the magnet. . In this way the error action is safely prevented. In addition, the switching path for unlocking the lever can be reduced to a minimum when the magnet acts with the control element in the area of the latching recess, so that the force is the result of the minimum movement of the control element from the latching recess or the latching receiver. Will act on. The influence of gravity is also reduced by the magnetic force, so that the ejector device according to the invention can be easily installed in different positions, for example the overhead position, where the lever is directed downward. As a result of the simple unlocking of the lever, this ejector device can also be used particularly well for those with a wide range of drawers and very fine panel gaps. It is also clearly possible to provide several magnets on the lever instead of one magnet.

There is also provided a push device comprising a body in which the push element is displaceably held through one or more drawing guides, wherein the push element can be released through the ejector device according to the invention. The ejector device may be secured to the rear side of the push element and cooperate with a lever on the rear wall or stop to move the push element from the closed position to a slightly open position.

Preferably, the push device is provided with a first ejector device which is operated over a longer distance than the tumbler device, for example arranged as an automatic retracting device. The push element can be moved to the closed position by the closing means by pressure and the lever can be latched.

According to a further embodiment, the lever remains adjustable in the opening direction on the push element. Thus an adjustment can be made after mounting the lever on the push element, for example to adjust the size of the panel gap of the front panel relative to the furniture body. The adjustment can take place, for example, via an eccentric mechanism or any other adjustment device capable of displacement of the lever in the open and closed directions even after the lever is mounted.

Also, a first ejector device may be provided in the push device, the ejector device being able to move the push element from a closed position to a slightly open position, and the second ejector device is effectively spaced apart from the first ejector device. to be. As a result, the push element can be latched in an intermediate position between the two ejector devices, for example via an automatic retracting device, in which each force on the push element is driven by the two ejector devices and the automatic retracting devices. This is because they partially overlap each other. This provides a high level of comfort for the user, since the user can selectively latch the push element in a slightly open or closed position.

Alternatively, the force of the first ejector device overlaps with the force of the automatic closing device or the automatic retracting device such that the second ejector is accelerated by the first ejector device in such a way that it reaches without any intermediate position and then the push element It will be further accelerated by the ejector device. As a result of splitting the ejector forces between two or more ejector devices, the triggering force for the first ejector device will decrease and the push element will accelerate over a longer distance. In addition, the triggering field over the entire panel will be achieved when the push elements are arranged as drawers. Ejector devices may be arranged spaced apart from one another or partially overlap each other.

The self-closing device will ensure that the roller on the lever of the first ejector device always lies on the stop in the latched state of the release mechanism. As a result, direct response of the release mechanism is ensured. Further, the push element cannot be moved from the furniture body improperly, for example by vibration or tilting of the furniture body in the open direction.

As a result of the manual opening of the push element, the automatic closing device can be overcome. If the second ejector device is in the engaged state, the user will be supported at least during the opening of the push element. The release mechanism of the second ejector device remains latched during manual opening in the opening direction.

If the self-closing device is engaged with the actuator on the running rail of the drawing guide during the closing process, the push element will close on the stop until the contact of the roller on the lever of the second ejector device.

The next opening process can optionally be triggered by pressing in the closing direction or by pulling in the opening direction on the push element.

Preferably, a retaining element is provided that is at least partially coupled around the lever and that holds the lever in the closed position with the push element. As a result, the lever includes the function of automatically closing the push element together with the retaining element, thereby eliminating the need for an additional automatic retracting device. The retaining element may be arranged in a bendable manner to release the lever when exceeding the predetermined tensile force.

In the following, the present invention will be described in more detail with reference to various embodiments shown in the accompanying drawings.

The ejector device 1 comprises a lever 2, on which one roller 3 is rotatably held. The roller 3 comprises protruding pins 4, with opposite sides of the protruding pins fixed in the receiver between the two legs 5, which legs 5 are arranged integrally with the lever 2.

The lever 2 is rotatably mounted about the axis 7 of the housing 6, which has a front wall 16 connecting the two side walls 60 to each other. The groove-shaped curved guide 14 is formed concave inside each of the side walls 60, and the curved guide includes an outwardly open channel 15 for mounting the control element 11. The control element 11 is arranged as a cylindrical rod and comprises a ring 12 projecting radially at the opposite ends, with the ring 13 protruding laterally to the ring. The pins 13 are each displaceably held in the curved guide 14.

The control element 11 penetrates a long hole 9 which is concave in the lever 2. The long hole 9 comprises an extended head section 10 through which the control element 11 is inserted in a balanced manner with the annular disk 12, so that it is axially within the long hole 9. Can be displaced in a safe manner. The elongate hole 9 extends in alignment with the rotational axis and rotational axis 7 of the roller 3 and is opened by the roller 3 and the rotational axis 7 in its plane so that the control element 11 is levered. It can move in the long hole 9 in the radial direction of (2).

The lever 2 is preloaded by the spring 17 in the open direction, with the legs 17 hanging on the front wall 16 with a leg 18 hanging on the lever 2. have.

3 to 6 show the function of the ejector device 1 in different positions.

3a and 3b show the lever 2 arranged in the closed position. The control element 11 is arranged with a pin 13 on the latching recess 20, which is formed by a protrusion in the loop-shaped section of the curved guide 14. The spring 17 pushes the lever 2 to the right around the axis 7, so that the pin 13 lies in the latching recess 20.

In order to unlock the lever 2 from the latching position, the lever is first pressed in the closing direction (FIGS. 4A and 4B), so that the lever 2 will be pivoted in the counterclockwise direction. As a result, the control element 11 is pressed by the pin 13 against the guide bevel 21 of the curved guide 14 and downwards into the run out channel 22 of the curved guide 14. Is displaced in the long hole 9.

After unlocking of the control element 11, the control element can be freely displaced in the curved guide and reaches the extension channel 23 of the group-shaped section from the run-out section 22. The lever 2 will be pivoted clockwise by the force of the spring 17 to the end channel 24 and its stop will place the pins 13 in a slightly open position of the lever 2 (FIG. 5A). And Figure 5b).

In order to move the lever 2 back to the closed position, components such as movable furniture parts will be pressed against the roller 3 on the lever 2 and will move the lever counterclockwise. Thus, the control element 11 with the pin 13 is arranged in a run-in channel 25 on the loop-shaped section and adjacent to the latching recess 20. 26) (FIGS. 6A and 6B). The user can now release the movable component in this position, so that the spring 17 will again push the lever clockwise, whereby the control element 11 with the pin 13 has an upper run-out channel. It will be moved from 26 to the latching recess 20, again to reach the position as shown in Figs. 3A and 3B.

7A-10B show the ejector device of FIG. 1 with the furniture 30 installed. The furniture 30 includes a furniture body 32, on which one or more push elements 35 remain displaceable. The push element 35 is arranged as a drawer comprising the front panel 31. The housing 6 of the ejector device 1 is mounted on the opposite side of the front panel 331, on which the lever 2 is pivotally held. An angle is formed in the furniture body 32, which angle forms a stop 34 for the lever 2 with one leg. 7A and 7B show the drawer in the closed position.

In order to unlock the ejector device 1, the front panel 31 is pressed further in the closing direction to the inside of the furniture body 32. As a result, the rear stop surface 70 of the housing 6 reaches the rear wall 33 of the furniture body. This is only for restricting the path, not for unlocking. In order to release the locking, the lever 2 is pressed by the roller 3 against the stop 34 so that the lever is pivoted slightly in the counterclockwise direction and the control element 11 is moved out of the latching recess 20. (FIGS. 4A and 4B).

After unlocking, the ejector device 1 pivots the lever 2 clockwise by the force of the spring 17 and places the lever on the stop 34. As a result, the push element 35 is moved to a slightly open position, as shown in FIGS. 9A and 9B.

After reaching the slightly open position, the push element 35 can now be displaced independent of the ejector device 1, where the lever 2 is a stop 34 as shown in FIGS. 10A and 10B. Spaced apart from the In order for the push element 35 to return to the closed position, the lever 2 is moved in the closing direction until it rests on the stop 34 and then reaches a position as shown in FIGS. 6A and 6B. Until counterclockwise in one direction and against spring 17. The front panel 31 or the handling element will then be released sequentially so that the spring 17 will slightly open the push element 35 and thus lock the push element on the ejector device 1.

11A-11C show the push element 35 in more detail. The push element 35 has a box-shaped configuration in which the front panel 31 is fixed. The drawing guides 40 are arranged on opposite sides of the push element 35, on which the push element 35 remains displaceably. The two housings 6 are fixed to the rear wall 33 of the push element 35, with one lever 2 pivotably held in each of the housings. The levers 2 are connected to each other by rods 36 and thus can only be moved in a combined state. Thus unlocking of the two ejector devices 1 can also occur in the case of side loading of the front panel 31. An angle 34 is fixed to the furniture body 32 for each ejector device 1, which angle forms a stop for the lever 2 with one leg.

12A and 12B show the drawing guide 40 to which the push element 35 is displaceably fixed. The drawing guide 40 includes a guide rail 41 mounted on the furniture body 32. The travel rail 42 is displaceably mounted on the guide rail 41 by selectively sandwiching one or several intermediate rails, to which the push element 35 is fixed. The web-shaped actuator 44 is fixed to the travel rail 42, which may be connected to the automatic retracting device and the second ejector device.

The housing 43 is arranged on the drawing guide 40 for this purpose, on which the curved guides are arranged for the first driver 45 and the second driver 48. The first driver 45 is displaceably retained on the curved guide, including a bent-off end section on opposite sides, where the driver 45 is pivoted at its vent-off end section. And release the actuator 44. The driver 45 is preloaded in the closing direction through the retraction spring 47. In this process, the driver 45 is displaceable over a path along a curve guide which is shorter than the path of the push element 35 which is moved to a slightly open position by the lever 2 of the ejector device 1. Therefore, when the push element 35 is moved in the open direction, its opening movement will first be supported by the lever of the ejector device 1, and the push element 35 accelerated in this way will travel the rail 42 in the open direction. Move it further). After this short distance, for example 0.5-5 cm of movement, the actuator 45 reaches the vent-off end section and pivots there, such that the actuator 44 can be moved independently of the actuator 45. The actuator 44 is now engaged with the second driver 48 and remains displaceable on the housing 43 along the additional curved guide. The curved guide includes a vent-off section such that the actuator 44 pulls the driver 48 from the vent-off end section, after which the driver 48 is opened in the open direction by the force of the opening spring 50. Will be pulled. As a result, the opening movement of the push element 35 is again supported by the second ejector device. A receiver 49 for the actuator 44 is provided on the driver 48 such that the coupling between the actuator 44 and the second driver 48 is ensured in the linear section of the curved guide. Similarly, the first driver 45 includes a receiver 46 for the actuator 44. During extension of the push element 35, the actuator 44 is disengaged and can run freely above the driver 48.

13 shows a rod-displacement diagram for the push element 35. In the wide open range, the first ejector device 81 and the second ejector device 82 and the automatic closing device 83 (for example arranged as an automatic retracting device) do not work and the push element 35 It can be freely displaced through the travel rail 42. When the push element 35 is moved in the closing direction, the actuator 44 must be connected to the driver 48 so that the second ejector device 82 is activated first, and now the opening spring 50 to be overcome in the closing direction. Power is needed. When the driver 48 reaches the vent-off end section of the curved guide, the driver 48 pivots and releases the actuator 44. As a result, no force acts on the actuator by the second ejector device 82 in the short transition region. The rollers 3, 3 ′ of the ejector device 1, 1 ′ then rest on the stop 34. When the push element 35 needs to be moved to the fully closed position, the force of the spring 17 needs to be overcome and the push element 35 has the ejector device 1, 1 ′, 81 in the closed position. It needs to be fully pressurized inside the furniture body 32 to latch. The actuator 44 also engages the actuator 46 and is pulled in the closing direction as a result of the force of the contraction spring 47. The rod-displacement diagram also shows the system friction 84 and the resulting force progression.

14 shows a modified embodiment of the ejector device 1 ′ in which the pivotable lever 2 is held on the housing 6, as described in the previous embodiment. The rotatable roller 3 'is arranged on the lever 2 at the end side, the roller comprising several annular ribs, with annular recesses provided between the ribs. The roller 3 'is made of an elastic material and provides low noise transfer characteristics under impact loads as a result of the shape of the roller 3'. The roller 3 'may be placed on an annular stop 34 which is mounted on the furniture body.

The housing 6 is held on the push element via an adjustment mechanism such that the lever 2 can be adjusted with the housing 6 in the open direction. The adjusting mechanism comprises a plate 61 to which the housing 6 is fixed. The plate 61 is arranged at the protruding end adjacent to the mounting plate 64 fixed to the push element 35. Two pins 66 are fixed to the mounting plate 64 for this purpose and can be inserted into the respective openings at the bottom of the push element 35.

15 shows the individual parts of the adjustment mechanism. The pins 66 are secured to the plate 61 through the screws 67, and the pins 66 move separately when the screws 67 are tightened and clamped in the opening.

The long holes 62 vertically aligned in the open direction are formed concave in the plate 61 in the region of the mounting plate 64, into which the eccentric 63 is inserted. The eccentric 63 includes an eccentrically arranged pin 73 that is inserted inside the central opening 64 on the mounting plate 64. In addition, two pins 68 are provided which are inserted inside the openings on the plate 61 and are respectively guided in the elongated holes 69 on the mounting plate 64 in the open direction.

16A and 16B, the adjustment mechanism is shown at the position where the pins 68 are arranged in the middle region of the long hole 69. From this position, the pin 68 can be displaced by the rotation of the eccentric 63 by the length t in the closing direction and by the length s in the opening direction, thereby causing the steering range v. A tool receiver is arranged in the eccentric 63, for example a screwdriver, so that the open position can be set by rotating the eccentric 63 from the bottom side of the push element.

17A and 17B show the adjustment mechanism in the maximum position in the closing direction. The pins 68 have reached the end of the long hole 69.

The eccentric 63 is tightened in the opposite direction in FIG. 18 so that the pins 68 are arranged in the maximum open position.

The steering process is performed in the furniture in the manner as shown in Figs. 19A and 19B. In FIG. 19A, the front panel 310 is arranged immediately adjacent to the furniture body 32 such that the initial panel gap y is reduced by the distance t.

In FIG. 19B, the opening gap is enlarged between the front panel 31 and the furniture body 32, and the initial opening gap y will be enlarged by the distance s. As a result, subsequent alignment of the front panel 31 with respect to the furniture body 32 can occur by the steering mechanism.

In FIG. 20, the push element 35 arranged as a drawer is shown with a mounted ejector device. The ejector device is held on the plate 61 together with the housing 6, where the plate 61 is steerable with respect to the mounting plate 64.

The illustrated invention is not limited to the illustrated embodiment. It is apparent that one or several ejector devices 1 may be attached to the push element 35. The push element 35 may also be arranged as a sliding door or any other linearly movable component instead of a drawer. In addition, the ejector device 1 can also be obviously used for flaps, doors and other moving components.

In another embodiment (not shown), the push element 35 may be latched at an intermediate position between the effective areas of the two ejector devices. In this case, the automatic retracting device is provided with a larger effective area than the first ejector device and the automatic retracting spring presses the push element against the lever 2 of the ejector device 1. The force of the spring 17 of the ejector device 1 will then be greater than the force of the automatic retracting spring to enable such intermediate latching.

FIG. 21 shows another embodiment of an ejector device with a pivotable lever 2 which is retained on the housing 6 and comprises a rotatable roller 3 ′ on the end side according to the embodiment as shown in FIG. 14. Illustrated. The lever 2 is penetrated by a control element 11 movable within the curve guide 14. The housing 6 is fixed to the plate 97, which has a recess 100 into which the protrusions on the housing 6 are inserted inward. The plate 97 also includes slits 98 elongated in the direction of movement of the push element 35. The latching element 107 is engaged in the slit 98, the latching elements sliding in the slit 98 during the adjustment process. The slits 98 comprise guideways through which the protrusions of the latching elements 107 can slide.

Furthermore, a mounting plate 101 is provided which can be fixed to the push element 35, for example by screws, which engage through the opening 102. A receiver 103 having an opening 104 for the rotatable bearing of the adjusting screw 105 is provided on the mounting plate 101, wherein the adjusting disk 105 is fitted with a pin 96 in the opening 104. And a rib-type endless adjustment screw 106. The adjusting disk 105 protrudes above the mounting plate 101 and can thus be tightened by hand. As shown in FIGS. 22A-22C, as an alternative, the pin 96 includes a tool receiver 108 to enable operation with the tool.

FIG. 23 shows that the plate 97 includes a row of adjacent protrusions 99 on the side facing the steering disc 105, the protrusions engaging between the infinite steering screw 106 so that the plate 97 is steered. It will be displaced relative to the mounting plate 101 during the rotation of the disk 105. As a result, the housing 6 can be moved together with the lever 2 in the direction of movement of the push element 35. Therefore, the adjustment of the panel can occur through the adjustment disk 105 as shown in FIG.

25A-26E show the previously described ejector device secured to the push element 35, wherein the lever 2 with the roller 3 ′ rotatably held on the housing 6 is angled. And is placed on the formed stop portion 34. The flexible holding element 55 is further provided on an angle 34, for example a leaf spring.

25A shows the push element 35 in the closed position, in which the front panel 31 is arranged at a short distance from the furniture body 32. If a slight tension force acts on the front panel 31, the retaining element 55 prevents the opening of the push element 35, which is retained by the retaining element 55, engaging over the roller 3 ′ and pushing the element 35. Is to prevent the opening).

When the front panel 31 is pressed in and the latching mechanism is unlocked (FIG. 25B), the housing moves further inside the furniture body and the lever 2 with the roller 3 ′ remains in an unchanged position for the time of stay. do. After unlocking the latching mechanism, the lever 2 is pressed on the stop 34 and pivoted clockwise. As a result, the roller 3 'slides downward and moves away from the retaining element 55 (FIG. 25C).

FIG. 25D shows the push element 35 in the open position where the lever 2 is spaced apart from the stop 34 and the retaining element 55. When the push element 35 comes back to the closed position, the lever 2 with the roller 3 'first reaches the stop 34, after which the roller 3' is on the retaining element 55. It is pivoted until it is released. Then, a position as shown in FIG. 25A is reached.

FIG. 26A shows the ejector device shown in FIG. 25 in a closed position. If a tension force acts on the front panel 31 instead of a pressing-in force, the flexible retaining element 55 will first hold the roller 3 'with the lever 2 in the closed position, where The latching mechanism is not latched. However, if the predetermined force is exceeded, the retaining element 55 will be bent upwards (FIG. 26B) and the roller 3 ′ on the lever 2 will move away from the stop 34. The push element 35 will then be opened by overcoming the spring force of the retaining element 55 (FIG. 26C). FIG. 26D shows the push element 35 in the open position, in which the lever 2 which is not triggered is spaced apart from the stop 34.

When the push element 35 is moved back to the closed position, the lever 2 with the lever 3 'first reaches the retaining element 55 and bends toward the stop 34. As a result of the force of the retaining element 55, the lever 2 is pivoted slightly counterclockwise, so that the latching mechanism will be triggered. The push element 35 will then be moved in the open direction after the triggering of the latching mechanism. The push element 35 can then be moved by the user in the closing direction until the latching mechanism is latched. In this process, the lever 2 is again displaced upwardly along the stop 34 under the retaining element 55 until the position shown in FIG. 26A is reached. This process protects the ejector device from damage to the components.

In the embodiment as shown in FIGS. 25 and 26, the retaining element 55 is provided with a flexible construct (eg, a leaf spring made of plastic or metal). It is also possible to disable the opening of the push element 35 by pulling the front panel 31 by arranging the retaining element in a dimensionally stable manner. Opening of the push element 35 can only occur by indenting and unlocking the latching mechanism.

27 and 28 show another embodiment of the ejector device according to the invention, wherein the lever 2 is rotatably held about an axis 7. The rotatable roller 3 'is arranged on the lever 2 at the end side, which roller is held by the pins 4 on the legs 5 of the lever 2. A ring 3 "made of plastic material is placed on the roller 3 ', in particular rubber rings, to prevent collision noises when the roller 3' or the ring 3" strikes the stop 34. do.

The housing 6, in which the lever 2 is pivotally held, is disposed on a plate 97 ′ which is displaceably held on the mounting plate 101 ′. For this purpose, the plate 97 'includes webs 98' in the wedge, which are held in respective side guides on the mounting plate 101 '. The guides include inward protrusions 107 'that engage over the webs 98'. The receiver 103 'with the opening 104' is arranged on the mounting plate 101 'as in the previous embodiment, and the steering disk 105' with the endless adjustment screw 106 'on the mounting plate. Is rotatably maintained. Infinite steering screw 106 ′ engages in protrusions that are arranged at the bottom of plate 97 ′, thereby allowing the steering disk 105 ′ to set the panel gap or to align the position of housing 6 in any manner. The position of the plate 97 'will be changed by the rotation of.

A receiver 56 for the leg 18 of the spring 17 is arranged in the housing 6 in the side wall 60. The legs 18 arranged opposite the springs 17 will be inserted into the receiver 57 recessed in the lever 2.

A recess for the magnet 110 is further formed in the lever 2 adjacent to the long hole 9. The magnet 110 exerts an attractive force on the control element 11, which consists of metal, preferably steel. In order to take advantage of the advantageous effects, the control element 11 is preferably made of a ferromagnetic material.

29 and 30 show the ejector device in the closed position of the push element with the locked control element 11. The roller 3 'of the lever 2 may be placed on the stop 34 as described with reference to FIGS. 25 and 26. In the closed and locked positions, the pin 13 of the control element 11 is arranged in the latching recess 20 or the latching receiver of the curved guide 14. The magnet 110 is disposed slightly below the control element 11 and pulls the control element 13 downward into the long hole 9 by the magnetic force acting in the direction of the arrow 111. The control element 11 can not be moved downward because it is held by the pin 13 on opposite sides in the latching recess 20.

If the lever 2 is now unlocked by the movement of the push element in the closing direction, it will reach a position as shown in FIG. 31. Immediately after pivoting of the lever 2 in the counterclockwise direction, the magnet 110 pulls the control element 11 downward into the run-out channel 22, whereby the control element 13 is unlocked. Although mechanical unlocking by displacement of the control element 11 according to the guide bevel 21 is possible in case of sudden movement, the control element 11 does not need to travel with respect to the guide bevel 21. In addition, the control element 11 should not be unlocked by the force of the magnet 110 even in the case of an overhead installation in that the control element 11 is moved against gravity.

In FIG. 32, the lever 2 is pivoted even more counterclockwise, so that the control element 11 will travel by the pin 13 inside the run-out channel 22. When the push element is released, the lever 2 will pivot clockwise by the force of the spring 17 and will release the push element. As a result, the control element 11 will be displaced on the pins 13 along the curved guide 14 in the extension channel 23 of the loop-shaped section until it reaches a position as shown in FIG. 33. . The loop-shaped section includes a corner region, with the end channel 24 omitted. When the control element 11 reaches this corner region, the lever 2 is in its end position.

As shown in FIG. 34, the control element 11 is adjacent to the magnet 110 which pulls the control element 11 upward along the long hole 9, as symbolically shown by the arrow 112. It is in the end position of the lever 2. The corner area forms a branch for the control element 11 because the control element 11 can be selectively moved back into the extension channel 23 or back into the run-in channel 25. As a result of the force of the magnet 110, the control element 11 is held on the side of the run-in channel 25 away from the extension channel 23, so that improper behavior is safely prevented.

As shown in FIG. 35, the control element 11 is arranged with the pin 13 on the upper wall of the run-in channel 25 even when the control element 11 is pulled downward by gravity. Since gravity is less than the force of the magnet 10, the control element 11 is moved along the upper wall of the run-in channel 25 towards the distance from the extension channel 23.

The lever 2 is pivoted again counterclockwise during the retraction of the push element until the position as shown in FIG. 36 is reached. The control element 11 is moved into the upper run-out channel 26 so that the push element is now released and the spring 17 pivots the lever 2 clockwise. As a result, the control element 11 is pushed back into the latching recess 20 and reaches a position as shown in FIGS. 29 and 30.
