Description

The present invention relates to a pushing device, in particular for furniture or household appliances, according to the preamble of claim 1.

The DE 20 2006 020 236 discloses a device for opening and closing a movable furniture part, in which a locking unit is provided with at least two locking elements which are synchronously coupled to each other and play substantially free of play. One of the locking elements has a locking mechanism, so that a furniture part can cause an unlocking by pressing and then ejected in the opening direction. This device is constructed comparatively complex with a variety of items and requires much space because of the two separate locking elements.

The EP 1 598 509 discloses a locking device for movable furniture parts, in which a plunger is latched via a latching mechanism against the force of a spring in a retracted position. Upon depression of the plunger, the latching mechanism can be unlocked to eject a movable furniture part.

The AT 008 730 discloses a device for opening and closing a movable furniture part, wherein at a rear wall of a drawer, two spaced Federschnapper are provided which are coupled together via a torsion bar.

It is therefore an object of the present invention to provide a pusher with an ejection device for movable furniture parts, which is compact and allows in conjunction with a push device user-friendly handling.

This object is achieved with a pusher with the features of claim 1.

According to the invention, a latching mechanism is arranged on the lever, by means of which the lever can be latched in a closed position against the force of the spring. Therefore, after unlocking, the component can be ejected in an opening direction, and then the lever can be locked by the component again in the closed position. As a result, the ejection device can be made particularly compact and can be independent of other guide elements, a self-closing or dampers are arranged. The ejection device designed in this way can be used in particular for movable furniture parts, such as drawers, sliding doors or flaps.

Preferably, the locking mechanism comprises a cam guide with a loop-shaped portion on which a detent recess is formed. In this case, a control may be mounted on the lever, which is guided in the cam guide. The control element may comprise at least one pin, which engages in the cam guide and is slidably mounted on the lever. For this purpose, the control may be formed as a rod which engages through a slot in the lever, so that on opposite sides of the lever a pin protrudes, which is held in each case in a curved guide. This allows a particularly stable locking of the lever. For unlocking can be arranged adjacent to the detent recess a run-on slope, by means of which the rod is displaceable relative to the lever when the lever is pivoted, so that in a simple manner takes place unlocking and only a small distance is required for the unlocking.

Preferably, the lever is rotatably mounted on a housing, on which a cam guide is formed. The housing may comprise two side walls, each having on their inner sides a groove-shaped curve guide in which the control is performed. As a result, the cam guide and the control element are arranged in the housing or in the lever in a protected manner. It is of course also possible to form the Kurverführung on the lever and to provide a control on the housing, such as a sliding pin.

According to one embodiment of the invention, the ejection device comprises a plurality of levers which are coupled to one another via a connecting element and movable together. Especially when using the ejection device on a rear wall of a drawer, it may be necessary to provide distributed over the width of the drawer more ejection devices. Then, a single triggering of a jetting device is prevented because they are moved together over the connecting element.

The ejection device may further comprise at least one pullout guide on which a pusher element is movably held. The ejection device may be mounted on the push element, the housing of the ejection device optionally being attached to a stationary component, such as a furniture carcass, or mounted on the pusher. To unlock the lever, the pusher can then be retracted in the closing direction, so that the lever is moved against the force of the spring and unlocked.

In a further variant, a magnet is provided on the lever, by means of which the control element can be influenced. The control is preferably made of metal, so that at certain positions of the cam guide the magnet acts on the control, in particular in areas of a branch, where the control could be moved in the wrong direction without the action of the magnet. As a result, a misoperation is reliably avoided. In addition, the switching path for unlocking the lever can be reduced to a minimum when the magnet acts on the control in the region of the detent recess, so that acts by a minimal movement of the control from the detent recess or locking receptacle out a force on the control. By the magnetic force and the influence of gravity is reduced, so that the ejection device according to the invention can be easily installed in different positions, for example, also directed overhead and with the lever down. By simply unlocking the lever, this ejector can also be used particularly well with wide drawers and a small aperture gap. Of course, it is also possible to provide a plurality of magnets instead of a magnet on the lever.

According to the invention, a push device is provided which comprises a body on which a push element is movably held via at least one pull-out guide, wherein the push element can be ejected via an ejection device. The ejection device can be fixed to a rear side of the thrust element and cooperate with a lever on a rear wall or a stop to move the thrust element from a closed position to a slightly open position.

Preferably, the pushing device is equipped with a first ejection device, which is effective over a longer distance than the tumbler, which is designed for example as a self-closing device. By pushing the pusher can then be moved to the closed position and the lever can be locked.

According to a further embodiment, the lever is adjustably held in the opening direction on the thrust element. This can be done after mounting the lever to the pusher still a setting For example, to adjust the size of the aperture gap of a front panel relative to a furniture body. The adjustment can be done for example via an eccentric mechanism or another adjusting device, which allows a displacement of the lever in the opening direction and closing direction with mounted lever.

Further, in a pusher, a first ejector may be provided which can move the pusher from a closed position to a slightly open position and a second ejector which is spaced from the first ejector. Thereby, the pusher can be locked in an intermediate position between the two ejection devices, for example via a self-closing, since the respective forces on the thrust element by the two ejection devices and the self-closing partially overlap. This provides a high degree of ease of use, as the user can lock the pusher either in a slightly open position or in the closed position.

Alternatively, the force of the first ejector superimposes the force of the locking mechanism so that the first ejector accelerates the pushing member to reach a second ejector without an intermediate position and then further accelerates the push member from this second ejector. By sharing the ejection forces on at least two ejector devices, the firing force for the first ejector is reduced and the pusher is accelerated over a longer distance. Furthermore, a trip field of almost the entire panel, if the pusher is designed as a drawer, achieved. The ejection devices can be arranged at a distance from each other or partially overlap.

The locking device causes the roller on the lever of the first ejection device always comes to rest against the stop in the latched state of the trigger mechanism. Thus, a direct response of the trigger mechanism is ensured. Furthermore, the pusher can not be unintentionally moved out of the carcass, e.g. by vibrations or an inclination of the body in the opening direction.

By manually opening the thrust element, the locking device can be overcome. Once the second ejector is engaged, the user is at least assisted in opening the pusher. At the Manual opening in the opening direction, the release mechanism of the second ejector remains locked.

If, during the closing operation, the locking device comes into engagement with the activator on the runner rail of the pullout guide, the push element is closed until it rests against the lever of the second ejection device at the stop.

The next opening process can be triggered either by pressure in the closing direction or train in the opening direction on the pusher.

According to the invention a lever at least partially embracing holding element is provided, which holds the lever together with the pusher in a closed position. This allows the lever together with the holding element have a Zuhaltefunktion for the pusher, so that no additional self-closing is required. The holding element is designed to be bendable in order to release the lever when a predetermined tensile force is exceeded. As a result, damage to the retaining element is avoided.

An ejection device 1 comprises a lever 2, at one end of a roller 3 is rotatably mounted. The roller 3 has on opposite sides protruding pins 4, which are fixed in a receptacle between two legs 5, wherein the legs 5 are formed integrally with the lever 2.

The lever 2 is rotatably mounted about a shaft 7 on a housing 6, wherein the housing 6 has a front wall 16 which connects two side walls 60 together. On each inner side of the side walls 60, a groove-shaped cam guide 14 is recessed, which has an outwardly open channel 15 for mounting a control element 11. The control element 11 is designed as a rod which is cylindrical and has at opposite ends a radially protruding ring 12, on which a laterally projecting pin 13 connects. The pin 13 is held in each case in the cam guide 14 movable.

The control element 11 engages through a slot 9 which is recessed in the lever 2. The slot 9 comprises a thickened head portion 10, through which the control element 11 with the annular discs 12th can be pushed through so that it is then secured in the axial direction within the elongated hole 9 movable. The slot 9 extends in alignment with the axis of rotation of the roller 3 and the axis of rotation 7 or in the plane spanned by the roller 3 and axis of rotation 7, so that the control element 11 in the radial direction of the lever 2 in the slot 9 is movable.

The lever 2 is biased by a spring 17 in the opening direction, wherein the spring 17 rests with a leg 18 on the front wall 16 and with the opposite leg 19 on the lever second

In the FIGS. 3 to 6 the function of the ejection device 1 is shown in different positions.

In the FIGS. 3A and 3B the lever 2 is arranged in a closed position. The control element 11 is located with the pin 13 on a detent recess 20 which is formed by a projection in a loop-shaped portion of the cam guide 14. The spring 17 pushes the lever 2 about the axis 7 to the right and the pin 13 is thereby in the locking recess 20 at.

To unlock the lever 2 from the latched position, this is first pressed in the closing direction ( FIGS. 4A and 4B ), so that the lever 2 pivots counterclockwise. As a result, the control 11 is pressed with the pin 13 against a run-on slope 21 of the cam guide 14 and moves within the slot 9 down into an outlet channel 22 of the cam guide 14th

After unlocking the control element 11 this can be moved freely within the curve guide and passes from the outlet section 22 in an extension channel 23 of the loop-shaped portion. The lever 2 pivots clockwise by the force of the spring 17 to an end channel 24 with a stop on which the pins 13 in a slightly open position of the lever 2 abut ( FIGS. 5A and 5B ).

In order to move the lever 2 back into the closed position, a component, for example a movable furniture part, is pressed against the roller 3 on the lever 2 and moves it counterclockwise. As a result, the control 11 passes with the pin 13 in a retraction channel 25 on the loop-shaped portion and into an upper outlet channel 26 which is arranged adjacent to the latching recess 20 ( Figures 6A and 6B ). In this position the user can now release the movable member, so that the spring 17 again pushes the lever 2 in the clockwise direction, whereby the control element 11 is moved with the pin 13 from the upper outlet channel 26 to the detent recess 20, so that in the FIGS. 3A and 3B shown position is reached again.

In the FIGS. 7A to 10B is the ejector of the FIG. 1 shown in a mounting situation on a furniture 30. The furniture 30 comprises a furniture body 32, on which at least one push element 35 is movably mounted. The thrust element 35 is designed as a drawer, which has a front panel 31. On the opposite side of the front panel 31, the housing 6 of the ejector 1 is mounted, on which the lever 2 is pivotally mounted. At the furniture body 32, an angle is defined, which forms a stop 34 for the lever 2 with a leg. In FIGS. 7A and 7B the closing position of the drawer is shown.

In order to unlock the ejection device 1, the front panel 31 is pressed further in the closing direction in the furniture body 32. As a result, a rear abutment surface 70 of the housing 6 reaches a rear wall 33 of the furniture body. However, this is only the Wegbegrenzung, but not the unlocking. To unlock the lever 2 is pressed with the roller 3 against the stop 34, so that the lever is pivoted slightly counterclockwise and the control element 11 is moved from the detent recess 20 ( FIGS. 4A and 4B ).

After unlocking the ejector 1 can now pivot the lever 2 in the clockwise direction via the force of the spring 17, which is supported on the stop 34. Thereby, the pusher 35 is moved to a slightly open position, as in the Figures 9A and 9B is shown.

After reaching a slightly open position, the thrust element 35 can now be moved independently of the ejection device 1, wherein the lever 2 is arranged at a distance from the stop 34, as shown in Figures 10A and 10B. To bring the pusher 35 back into the closed position, this is moved in the closing direction until the lever 2 bears against the stop 34 and is then pivoted in a counterclockwise direction and against the force of the spring 17 until in the Figures 6A and 6B shown position is reached. Subsequently, the front panel 31 or a handle member is released, so that the spring 17 the Push element 35 opens slightly and thereby locked to the ejector 1.

In the FIGS. 11A to 11C the pushing element 35 is shown in detail. The push element 35 has a box-shaped construction, on which the front panel 31 is fixed. On opposite sides of the thrust element 35 pullout guides 40 are arranged, on which the thrust element 35 is movably held. On the rear wall 33 of the thrust element 35, two housings 6 are fixed, on each of which a lever 2 is pivotably mounted. The levers 2 are connected to each other via a rod 36 and thus can only be moved together. As a result, an unlocking of the two ejection devices 1 can take place even when there is lateral loading on the front panel 31. For each ejection device 1, an angle 34 is fixed to the furniture body 32, which forms a stop for the lever 2 with a leg.

In the FIGS. 12A and 12B a drawer guide 40 is shown, on which the thrust element 35 is movably held. The drawer guide 40 comprises a guide rail 41, which is mounted on the furniture body 32. On the guide rail 41, a running rail 42 is optionally movably mounted with the interposition of one or more center rails, on which the thrust element 35 is fixed. On the running rail 42, a web-shaped activator 44 is fixed, which can be coupled with a self-closing and a second ejection device.

For this purpose, a housing 43 is formed on the pullout guide 40, are formed on the cam guides for a first driver 45 and a second driver 48. The first driver 45 is movably mounted on a cam guide having an angled end portion on opposite sides, wherein at the end portions of the driver 45 can pivot and the activator 44 releases. The driver 45 is biased by a pull-in spring 47 in the closing direction. In this case, the driver 45 is movable over a distance along the curve guide, which is shorter than the distance of the thrust element 35, which is moved by the lever 2 of the ejection device 1 in a slightly open position. If the pusher element 35 is therefore moved in the opening direction, the opening movement is initially assisted by the lever 2 of the ejection device 1, wherein the thus accelerated pusher element 35 moves the running rail 42 further in the opening direction. After this short distance, for example, between 0.5 and 5 cm, the driver arrives 45 at an angled end portion and pivoted there, so that the activator 44 can be moved independently of the driver 45. The activator 44 now comes into engagement with the second driver 48, which is movably mounted on the housing 43 along a further cam guide. The cam guide has an angled end portion, so that the activator 44 pulls the driver 48 from this angled end portion and the driver 48 is then pulled over the force of an opening spring 50 in the opening direction. As a result, the opening movement of the pusher element 35 is again assisted by the second ejection device. At the driver 48 while a receptacle 49 is provided for the activator 44, so that in a linear portion of the cam guide, a coupling between the activator 44 and the second driver 48 is ensured. Similarly, the first driver 45 has a receptacle 46 for the activator 44. Upon extension of the pusher element 35, the activator 44 is disengaged, it can overrun the driver 48 freely.

In FIG. 13 a force-displacement diagram for the thrust element 35 is shown. In a wide-open area, the first ejection device 81 and the second ejection device 82 and the locking device 83, for example, designed as a self-closing device, are not effective and the thrust element 35 can be moved freely on the track 42. If the pusher element 35 is moved in the closing direction, first the second ejection device 82 is activated by the activator 44 is coupled to the driver 48 and now the force of the opening spring 50 must be overcome in the closing direction. When the driver 48 reaches an angled end portion of the cam guide, the driver 48 pivots and releases the activator 44. As a result, no forces act on the activator through the second ejection device 82 in a short transition region. Then comes the roller 3, 3 'of the ejector 1, 1', 81 for abutment against the stop 34. If the thrust element 35 is to be moved to the fully closed position, the force of the spring 17 must be overcome and the thrust element 35 completely in the Furniture body 32 are pressed so that the ejector 1, 1 ', 81 locked in the closed position. Furthermore, the activator 44 engages with the driver 46, which is pulled in the closing direction due to the force of the pull-in spring 47. Furthermore, the system friction 84 and the resulting force profile 85 are shown in the force-displacement diagram.

In FIG. 14 a modified embodiment of an ejection device 1 'is shown, in which a pivotable lever 2 is mounted on a housing 6, as described in the previous embodiment. On the lever 2 at the end a rotatable roller 3 'is formed, which has a plurality of annular ribs, between which annular recesses are provided. The roller 3 'consists of an elastic material and has due to the contour of the roller 3' a low noise in a shock load. The roller 3 'can be applied to an angular stop 34, which is mounted on a furniture body.

The housing 6 is held on the thrust element via an adjusting mechanism, so that the lever 2 can be adjusted together with the housing 6 in the opening direction. The adjusting mechanism comprises a plate 61 to which the housing 6 is fixed. The plate 61 is disposed at a protruding end adjacent to a mounting plate 64 which is fixed to a pushing member 35. For this purpose, two pins 66 are fixed to the mounting plate 64, which can be inserted into corresponding openings at the bottom of the thrust element 35.

In FIG. 15 the individual parts of the adjustment mechanism are shown. The pins 66 are fixed by screws 67 on the plate 61, wherein the pins 66 spread when screwing the screws 67 and jammed in an opening.

On the plate 61, a perpendicular to the opening direction aligned slot 62 is recessed in the region of the mounting plate 64, in which an eccentric 63 is inserted The eccentric 63 comprises an eccentrically arranged pin 73 which is inserted into a central opening 65 on the mounting plate 64. Further, two pins 68 are provided, which are inserted into the openings on the plate 61 and are each guided in a slot 69 on the mounting plate 64 in the opening direction.

In the Figures 16A and 16B the adjusting mechanism is shown in a position in which the pins 68 are arranged in a central region of the slots 69. From this position, the pin 68 can be moved by turning the eccentric 63 by the length t in the closing direction and the length s in the opening direction, thus resulting in the adjustment range v. In the eccentric 63, a receptacle for a tool is formed, for example a screwdriver, so that the opening position can be adjusted by turning the eccentric 63 from the bottom of the pusher element.

In the Figures 17A and 17B the adjusting mechanism is shown in a maximum position in the closing direction. The pins 68 have reached the end of the slots 69.

In FIG. 18 the eccentric 63 has been rotated in the opposite direction, so that the pins 68 are arranged in the maximum open position.

The adjustment process looks like the furniture, as in the Figures 19A and 19B is shown. In Figure 19A is the front panel 31 immediately adjacent to the furniture body 32, so that the initial diaphragm gap y was reduced by the distance t.

In FIG. 19B the opening gap between front panel 31 and furniture body 32 has been increased, wherein the initial opening gap y was increased by the distance s. As a result, subsequent alignment of the front panel 31 relative to the furniture body 32 can be effected by the adjusting mechanism.

In FIG. 20 is designed as a drawer thrust element 35 with mounted ejector shown. The ejection device is held on the plate 61 with the housing 6, wherein the plate 61 is adjustable relative to the mounting plate 64.

The illustrated invention is not limited to the embodiment shown. Of course, one or more ejectors 1 may be attached to a pusher 35. Instead of a drawer, the thrust element 35 may be formed as a sliding door or other linearly movable component. In addition, the ejector 1 can of course be used for flaps, doors or other movable components.

In a further embodiment, not shown, the thrust element 35 can be locked in an intermediate position between the range of action of two ejection devices. Then the self-retraction has a greater range of action than the first ejector and the Selbsteinzugsfeder pushes the pusher against the lever 2 of the ejector 1. The force of the spring 17 of the ejector 1 is then greater than the force of the Selbsteinzugsfeder to allow such intermediate latches.

In FIG. 21 a further embodiment of an ejection device with a pivotable lever 2 is shown, which corresponds to the in FIG. 14 shown embodiment is mounted on a housing 6 and end a rotatable roller 3 'has. The lever 2 is penetrated by a control 11 which is movable in a cam guide 14. The housing 6 is fixed to a plate 97, wherein the plate 97 has a recess 100, in which a projection on the housing 6 is inserted. Further, the plate 97 includes elongated slots 98 in the direction of movement of a thrust element 35. In the slots 98 engage locking elements 107, which slide in an adjustment process in the slots 98. The slots 98 have slideways on which projections of the locking elements 107 can slide.

In addition, a mounting plate 101 is provided, which is fixable to a thrust element 35, for example by screws which engage through openings 102. On the mounting plate 101, a receptacle 103 is provided with an opening 104 for rotatably supporting an adjusting plate 105, wherein the adjusting plate 105 engages with a pin 96 in the opening 104 and has a rib-shaped adjusting worm 106. The adjusting plate 105 protrudes beyond the mounting plate 101 and can therefore be rotated by hand. As in the Figures 22A to 22C shown, the pin 96 alternatively has a tool holder 108 to allow operation with a tool.

As in FIG. 23 can be seen, the plate 97 comprises on the side facing the adjusting disc 105 a series with adjacent projections 99 which engage between the adjusting screw 106, so that upon rotation of the adjusting plate 105, the plate 97 is displaced relative to the mounting plate 101. Thereby, the housing 6 can be moved with the lever 2 in the direction of movement of the thrust element 35. About the adjusting plate 105 can, as in FIG. 24 shown, thus made an adjustment of the aperture gap.

In the FIGS. 25A to 26E one of the ejector devices described above is fixed to a push element 35, wherein the rotatably mounted on the housing 6 lever 2 with the roller 3 'abuts against a stop 34 which is formed by an angle. At the angle 34, a bendable retaining element 55 is further provided, for example, a leaf spring.

In Figure 25A the push element 35 is shown in a closed position and a front panel 31 is located at a short distance to the furniture body 32. Now acts a slight pulling force on the front panel 31, prevents Retaining element 55, an opening of the thrust element 35, since the holding element 55, the roller 3 'overlaps and prevents the thrust element 35 opens.

If the front panel 31 is now pressed in and the latching mechanism is unlocked ( FIG. 25B ), the housing 6 moves into the furniture body further into and the lever 2 with the roller 3 'initially remains in the same position. After unlocking the locking mechanism, the lever 2 presses against the stop 34 and pivots in the clockwise direction. As a result, the roller 3 'slides downwards and moves away from the retaining element 55 (FIG. FIG. 25C ).

In FIG. 25D For example, the pusher 35 is shown in an open position and the lever 2 is spaced from the stop 34 and the retaining member 55. If now the thrust element 35 is again brought into a closed position, the lever 2 comes with the roller 3 'first to the stopper 34 and is then pivoted until the roller 3' rests against the holding element 55 again. Then the in Figure 25A reached shown position.

In Figure 26A is the in FIG. 25 Shown ejector shown in the closed position. Now acts instead of an indenting force on the front panel 31, a tensile force on the front panel 31, first holds the bendable support member 55, the roller 3 'with the lever 2 in a closed position, wherein the latching mechanism is not unlocked. However, if a predetermined force is exceeded, the holding member 55 bends upward ( Figure 26B ) and the roller 3 'on the lever 2 moves away from the stopper 34. Then, overcoming the spring force of the holding member 55, the pusher member 35 is opened. ( Figure 26C ). In Figure 26D the pusher 35 is shown in an open position in which the untriggered lever 2 moves away from the stop 34.

If now the thrust element 35 are brought back into a closed position, the lever 2 comes with the roller 3 'first to the holding element 55, which bends to the stop 34 back. By the force of the holding member 55, the lever 2 is slightly pivoted in a counterclockwise direction, so that the latching mechanism is triggered. The thrust element 35 is moved in the opening direction after the release of the latching mechanism. Thereafter, the pushing element 35 can be moved by the user in the closing direction until the latching mechanism engages. Here, the lever 2 is again moved along the stopper 34 upwards under the holding member 55 until the in Figure 26A shown position is reached. This process protects the ejector from component damage.

In the in the Figures 25 and 26 As shown embodiment, the holding member 55 is formed bendable, for example, as a leaf spring made of plastic or metal. It is also possible to form the retaining element 55 dimensionally stable, so that an opening of the thrust element 35 by pulling on the front panel 31 is not possible. Then, an opening of the thrust element 35 can be done only by pressing and unlocking the locking mechanism.

In the Figures 27 and 28 a further embodiment of an ejection device according to the invention is shown, in which a lever 2 is rotatably mounted about an axis 7. On the lever 2, a rotatable roller 3 'is arranged at the end, which is held with pins 4 on legs 5 of the lever 2. On the roller 3 'are rings 3 "of an elastic material, in particular rubber rings arranged to avoid impact noises when the roller 3' and the rings 3" impinge on the stop 34.

The housing 6, on which the lever 2 is pivotally mounted, is located on a plate 97 ', which is displaceably held on a mounting plate 101'. For this purpose, the plate 97 'edge webs 98', which are held in corresponding lateral guides on the mounting plate 101 '. The guides have inwardly directed projections 107 'which engage over the webs 98'. On the mounting plate 101 ', as in the previous embodiment, a receptacle 103' with an opening 104 'is formed, on which an adjusting plate 105' with an adjusting screw 106 'is rotatably mounted. The adjusting worm 106 'engages projections disposed on the underside on the plate 97' so that by rotating the adjusting plate 105 ', the position of the plate 97' is changed to adjust a diaphragm gap or otherwise align the position of the housing 6 ,

On the housing 6, a receptacle 56 for a leg 18 of the spring 17 is formed on a side wall 60. The formed on the opposite side of the spring 17 leg 18 is inserted into a receptacle 57 which is recessed in the lever 2.

Further, a recess for a magnet 110 is formed on the lever 2 adjacent to the slot 9. The magnet 110 exerts forces on the metal, preferably steel, existing control 11 from. To use the advantageous effect, the control element 11 is preferably made of a ferromagnetic material.

In FIG. 29 and 30 the ejector is shown in the closed position of the pusher with locked control 11. The roller 3 'of the lever 2 can rest against a stop 34, as he with the reference to the Figures 25 and 26 was explained. In the closed and locked position, the pins 13 of the control element 11 are in a detent recess 20 and locking receptacle of the cam guide 14. The magnet 110 is located slightly below the control element 11 so that a magnetic force acts in the direction of the arrow 111, the control 13th in the slot 9 pulls down. However, the control element 11 can not be moved down, because it is held with the pin 13 on the opposite sides in the detent recess 20.

If the lever 2 is now unlocked by a movement of the thrust element in the closing direction, the in FIG. 31 reached shown position. Immediately after pivoting the lever 2 in the counterclockwise direction, the magnet 110 pulls the control element 11 down to the outlet channel 22, so that the control element 13 is unlocked. It is not necessary for the control element 11 to run against the run-on slope 21, even if a mechanical unlocking by moving the control element 11 along the run-on slope 21 is possible in the case of a jerky movement. Even with an overhead installation, the control element 11 would be unlocked by the force of the magnet 110 by moving the control element 11 against the force of gravity.

In FIG. 32 the lever 2 has been pivoted even further counterclockwise, so that the control element 11 enters the outlet channel 22 with the pin 13. If the push element is now released, the lever 2 pivots clockwise by the force of the spring 17 and ejects the push element. As a result, the control 11 moves on the pin 13 along the cam guide 14 in an extension channel 23 of a loop-shaped portion until the in FIG. 33 shown position is reached. The loop-shaped section comprises a corner region, wherein the end channel 24 has been dispensed with. When the control element 11 reaches this corner area, the lever 2 is in its end position.

As in FIG. 34 is shown, the control element 11 is in the end position of the lever 2 adjacent to the magnet 110, which now pulls the control 11 upwards along the slot 9, as is symbolically represented by the arrow 112. The corner region forms for the control 11 a Branch off, since the control 11 can be moved either in the extension channel 23 back or in the insertion channel 25. Due to the force of the magnet 110, the control element 11 is held on the side facing away from the extension channel 23 of the retraction channel 25, so that a malfunction is reliably avoided.

As in FIG. 35 is shown, the control 11 is located with the pin 13 on the upper wall of the retraction channel 25, although gravity pulls the control 11 down. However, since gravity is less than the force of the magnet 110, the control element 11 is moved along the upper wall of the retraction channel 25, which faces away from the extension channel 23.

The lever 2 is pivoted counterclockwise again when retracting the thrust element until the in FIG. 36 shown position is reached. The control member 11 has been moved into the upper outlet channel 26 so that the pusher can now be released, so that the spring 17 pivots the lever 2 in a clockwise direction. Then, the control 11 is pressed back into the locking recess 20 and in the Figures 29 and 30 shown position is reached.
