Description

State of the art

Devices for influencing the movement of a movable furniture part of a furniture comprising a furniture body to which the movable furniture part via linear or pivot guide means attachable and movable relative to the furniture body in an opening direction and in an opening direction opposite closing direction are known.

To support the opening movement of the furniture part from the closed position on the furniture body, a loadable energy storage is often used. The charged energy storage leads to a triggering of the device by a user who acts on the furniture part in the closed position on the furniture body to the fact that under the action of the energy storage, the furniture part is moved or ejected at least over a partial distance in an opening direction.

The energy accumulator acts regularly on a displaceable ejector of the device and drives it, wherein the movement of the ejector is transferable to the movable furniture part by the ejector is present on the furniture part and this entrains in an opening direction. In order that the charged energy storage device does not discharge uncontrollably, it takes a locked, for example, until the device is triggered. Triggering position.

The triggering is preferably carried out with a user applied from the outside movement of the furniture part in the closing direction, wherein the ejector is displaceable and an actuator from a locked position is movable and the tensioned energy storage after deployment can exert its force on the furniture part.

It is disadvantageous if an action leads from the outside to a triggering, although the user does not want a conscious triggering.

Purpose and advantages of the invention

Object of the present invention is to improve the initially discussed devices, in particular to achieve a higher ease of use or to exclude unwanted operating errors.

This object is solved by the independent claims.

The dependent claims relate to advantageous variants of the invention.

The invention relates to a device for influencing the movement of a movable furniture part of a furniture comprising a furniture body to which the movable furniture part can be attached via guide means and in relation to the furniture body in an opening direction and in an opening direction opposite closing direction is movable, wherein the device loadable energy storage device comprises, so that with the device mounted on the furniture, the movable furniture part under the action of the charged energy storage in the opening direction is movable by the energy storage drives a displaceable ejector of the device and the displacement movement of the ejector is transferable to the movable furniture part, wherein the Power storage is connected to a movable actuator, which occupies a locked release position when the stored energy store, so that caused by the charged energy storage displacement of the ejector is prevented in the opening direction , wherein the ejector is displaceable in the closing direction with a release movement applied from the outside, so that the actuating element can be moved out of the locked release position and the tensioned energy storage after the release movement of the ejector moves the ejector in the opening direction and entrains the movable furniture part in the opening direction. The device according to the invention is preferably designed as a furniture opening device or is also referred to as furniture ejection or furniture ejector device.

The essence of the invention is that the device is designed such that, depending on the distance covered by the offset from the outside ejector in the closing direction, which covers the ejector from a setting time in which the actuator moves out of the locked release position, the Actuator either released from the lock or returns to the locked release position.

This advantageously provides a practical detection with the device, so that possible unwanted tripping of the device is precluded or vice versa, the device is only triggered if it can be safely assumed that the tripping is actually a conscious resp ., Is pertinent voluntary triggering of the device.

In practice, in the case of devices in question, which have in particular a so-called touch-latch release, a disadvantage is the fact that leaning of a person is pressed on the outside of the furniture or on a furniture part front and this unconsciously in a closing direction, to causes the device this as a trigger and as a result it to eject the furniture part comes, for example, a hitherto closed drawer, which is undesirable.

In touch-latch operation, a control operation is necessary for the triggering, wherein a defined impressions of the closed movable furniture part is in the closed position on the furniture body.

So far, a leaning of a user is not recognized as a false triggering disadvantageous and therefore expelled the furniture part as soon as the user is no longer leaning on the furniture part disadvantageously.

This is excluded with the invention. Because an intuitive impressions to trigger the device or the ejection movement is usually only a relatively short Eindrückweg of the closed furniture part, wherein the locked device is in tensioned power storage in a basic position. Everything that goes beyond the Eindrückweg, including a corresponding front gap between the closed furniture part and the furniture body is necessary, which goes beyond this Eindrückweg, according to the invention is not recognized as tripping. This leads to a leaning against the furniture part and thus its movement in the closing direction to a stop or under bridging the entire front gap not to trigger the device according to the invention and thus the furniture part remains as desired in the closed position on the furniture.

Preferably, when the furniture part is pressed in and the ejector is moved in the closing direction, the device is triggered only when the ejector travels from the previously assumed rest position or according to the basic position of the device to an insertion path which is greater than zero millimeters to a maximum of 0, 8 millimeters or up to a maximum of 1.2 millimeters, which can be specified. Everything that goes beyond that, so if the ejector z. B. over 0.8 or over 1.2 millimeters in the closing direction, does not lead to a triggering of the device. This will certainly happen, for example, whenever a person leans against the closed furniture part.

In a deliberate release for the intended opening of the movable furniture part, the pushing-in movement of the furniture part takes place only over a comparatively short movement in the closing direction of the furniture part z. B. to a maximum of 0.8 to 1.2 millimeters.

The adjusting element is preferably a pivotable lever of the device, which is coupled to the energy storage under the force of the tensioned energy storage in a first direction and in the opposite direction and over which the lock can be set. About the movement of the furniture part from the outside, with mounted device, the ejector and coupled with it, the actuator is moved and thus influenced the lock. After release, the tensioned or charged energy storage device acts accordingly on the ejector and thus on the furniture part.

The adjusting time is accordingly in particular the time when acting from the outside on the furniture part with the device in the basic position in which the hitherto stationary actuator is offset by the movement of the ejector caused from the outside.

For there may be movement phases of the ejector, in which the movement of the ejector does not cause any movement of the actuating element.

Further, it is advantageous that the device is designed in such a way that, when a predefinable length dimension is exceeded, the distance traveled from the setting time of the offset in the closing direction ejector, the actuator returns to the locked release position. It depends accordingly on the distance traveled by the ejector track in the closing direction. The specification of the length dimension of as explained above, for example, 0.8 to 1.2 millimeters, for example, via a projection on the actuator and a cooperating with the projection guide contour can be realized on a locking lever. The locking lever of the device is swinging back and forth in particular biased in a pivoting direction. The adjusting element and the locking lever are preferably both designed as a pivot lever, which are biased in each case a different pivoting direction. Under the respective bias, the free ends of the actuator and the detent lever move towards each other, for example in the manner of two vehicle windshield wipers.

Preferably, the length dimension can be predetermined by dimensions and / or shape of a latching contour or of the projection and / or of a latching section or of the guide contour.

In a covered distance of the staggered out of the basic position ejector in the closing direction, wherein the ejector rests in the basic position, which is below the length dimension, the actuator comes out of the locked release position and the energy storage pushes the ejector and thus the furniture part in the opening direction.

It is also advantageous that the device is designed such that a basic position of the Ejector is specified on the device in the locked release position of the actuating element, wherein a displacement movement of the ejector is limited from the basic position in the closing direction by a fixed stop. The fixed stop, for example, a wall portion is preferably formed on the device itself. Thus, the device is controlled within the operated up to the fixed stop ejector operable or triggered. When mounted device on the furniture, it is preferably such that a front gap of the furniture part in the closed position on the furniture body is at least so large that when pressing the closed furniture part in the closing direction of the ejector previously meets the fixed stop before the frontal gap is overcome by the furniture part , This ensures that the ejector can always reach the fixed stop.

Moreover, it is advantageous that a latching portion of the actuating element cooperates with a guide contour on a locking lever of the device. The latching portion is preferably a bent projection. The guide contour is preferably a recessed area in a flat latching lever, wherein the guide contour has a spatially existing locking edge, in particular a plurality of mutually angled edges and / or inclined to a plane of a base plate of the device ramp, where the projection can be brought into a stop position and / or defined guided past it. The guide contour accordingly preferably provides both a Verrastkontur for the locked release position of the device and the control element as well as a slotted guide for the projection and thus for the control of the control element.

An advantageous variant of the invention is given by the fact that the locked release position of the actuating element is determined by a trigger-locking contour on the locking lever, which acts as a stop for the locking portion of the actuating element. The release catch contour is preferably a latching edge on which the projection which forms the latching portion is present in the locked release position.

The stop preferably acts in a direction of the prestressed locking lever. In the other direction, a Rückweichbarkeit the locking lever against the bias and a spring force is given.

Moreover, it is advantageous that the latching portion of the actuating element and the guide contour are matched to the locking lever such that when the triggering position of the actuating element is locked by movement of the ejector in the closing direction, the actuating element from the locked release position reaches an intermediate position of the actuating element. The intermediate position is preferably only in the millimeter range spaced from the release position. Preferably, the actuator is biased in the intermediate position in the direction of the locked release position due to the tensioned force accumulator.

The adjusting element is preferably a pivotable adjusting lever. The ejector preferably acts so that when moving the ejector in the closing direction of the ejector abuts a moving element and moves it, wherein a connecting element connects the moving element and the actuating element. The actuator is accordingly brought from the Verrieglungsstellung in the intermediate position.

According to another advantageous variant of the invention, the locking portion of the adjusting element and the guide contour on the locking lever are tuned such that the actuating element returns from the intermediate position in the locked release position, if after reaching the intermediate position of the actuating element of the ejector initially moves in the closing direction. Thus, for example, when leaning a user against the closed furniture part and an associated further movement of the furniture part and thus the ejector on a conventional Eindrückweg addition, the ejection avoided.

One advantage is that the guide contour on the locking lever comprises a guideway along which the locking portion of the actuating element returns after leaving the intermediate position under the action of the energy storage in the locked release position. The guideway is preferably a locking edge or a guide surface, which is designed for a sliding along the projection.

Moreover, it is advantageous that the latching portion of the actuating element and the guide contour are matched to the locking lever such that the actuator from the intermediate position does not return to the locked release position, but released from the locking lever when after reaching the intermediate position of the ejector under the action of the charged force accumulator a take in the opening direction learns. This corresponds to a comparatively shorter Eindrückweg the furniture part during normal triggering. The projection on the actuator can then z. B. along a ramp of the guide contour and are raised parallel to the pivot axis of the actuating element and released via the ramp from the guide contour.

Advantageously, the adjusting element is pivotable about a pivot axis and the guide contour on the locking lever comprises an inclined surface which acts on the latching portion such that the actuating element from the intermediate position in one direction is displaceable parallel to the pivot axis, so that the adjusting element is free to move along under the action of the energy storage on the locking lever. The inclined surface is preferably a ramp. Thus, the actuator is released from the locked position on the locking lever and the energy storage pulls the ejector and thus the furniture part in the opening direction.

Another advantage is the fact that the locking lever is adjustable, wherein in a locking position of the locking lever, the trigger-locking contour of the locking lever acts as a stop for the locking portion of the actuating element. The stop indicates the locked release position. The latching lever is preferably pivotable back and forth and biased in a pivoting direction by means of a spring force. The locking lever is preferably biased in the direction of the locking position.

According to an advantageous variant of the invention, in a release position of the detent lever, the detent portion of the actuating element can be moved freely past the detent lever under the force of the charged force accumulator. In the release position, the inclined surface or the ramp of the locking lever comes into contact with the projection on the adjusting element, so that the projection on the ramp from the guide contour is released.

Another advantage is that a basic position of the ejector on the device in the locked release position of the actuating element is predetermined by the fact that the ejector is in the closing direction of a coupled to the actuator movable stop, wherein by an effected from the outside displacement of the ejector in the closing direction via the stop the adjusting element is mitbewegbar, whereby the locking portion of the actuating element comes out of contact with the trigger-locking contour of the locking lever. The ejector preferably has a shoulder which on the z. B. is formed as a movement element stop formed. The movement element is preferably coupled via a rigid rod or the connecting element with the actuating element.

The movement of the ejector takes place against the force of the energy storage. The basic position correlates with a closed rest position of the furniture part with mounted device. The movement of the ejector in the direction of the stop occurs via a movement of the furniture part in the closing direction with a triggering operation.

According to another advantageous embodiment of the invention, the locking lever is biased displaceable, so that the locking lever assumes a release position as soon as the actuator leaves the locked release position and the locking portion of the actuating element out of contact with the trigger-locking contour of the locking lever.

In the release position of the locking lever no locking of the actuating element takes place. In the release position, the actuator is free to move under the action of the charged energy storage as soon as the ejector no greater counterforce in the closing direction acts more.

Advantageously, the device is designed so that when exceeding a predetermined length of distance traveled from the setting time distance of the ejector offset from the outside in the closing direction, the ejector acts on the locking lever such that the locking lever is movable in a direction away from the release position.

The invention also extends to a piece of furniture with a furniture body and a movable furniture part which can be brought via guide means in an opening direction of the furniture part and in a direction opposite to the opening direction closing direction relative to the furniture body, wherein a device is provided according to one of the above embodiments.

An inventive furniture 50 with a box-shaped furniture body 51 and a guide means 52 movably guided drawer 53 is in 1 shown. The drawer 53 includes a drawer bottom 54 , a drawer front 55, two opposite side walls 56 and a Drawer rear wall 57 , For the guidance of the drawer 53 are two equally effective guides 52 each between each side wall 56 the drawer 53 and an associated body side wall 59. On an underside of the drawer bottom 54 is an ejector unit 1, 2 according to the invention (shown in dashed lines) for moving or ejecting the drawer 53 trained furniture part arranged in the opening direction M1.

The 1 assumes a mounting state of the ejector unit 1 on the drawer bottom 54 whereas the 3 to 14 from a mounting state of the ejector unit 1 positionally fixed relative to the furniture, for example, on a cabinet rail of the guide means 52 ,

The ejector unit 1 used for power assisted ejection of the drawer 53 over a first part of the opening movement of the drawer 53 from a closed position relative to the furniture body 51 in the opening direction M1 of the drawer 53 ,

The drawer 53 is about the guiding means 52 , For example, two similar partial or full extracts, the furniture body 51 slidably mounted in the opening direction M1 and M1 to the opposite direction of closing M2. The ejector unit 1 can alternatively on the furniture body 51 or at the guide means 52 of the furniture 50 be arranged.

The ejector unit 1 includes, inter alia, a base plate 1a, a power storage 3 , a coupling device 4, an ejector 5 , a locking lever 6 and a leadership contour 7 , The guide contour 7 is preferably on the locking lever 6 educated. The pivotable about a pivot bearing 32 about an axis perpendicular to the base plate plane locking lever 6 is also by means of an unrecognizable spring such. B. a bow spring biased counterclockwise, but evasive clockwise against the force of the spring.

A housing of the ejector unit 1 includes the base plate 1a and a cover member, not shown. The ejector unit 1 may be on the underside of the drawer bottom 54 and / or on the guide means 52 be arranged.

At the base plate 1a are holding sections, guide contours, stop members and / or receiving sections for connecting the individual components of the ejector unit 1 educated. The base plate 1a is designed substantially as a rectangular, elongated or strip-shaped component with a comparatively small height h of, for example, approximately 5 to 15 millimeters. The base plate 1a furthermore has a width b of about 4 to 10 centimeters and a length g.

The energy storage 3 comprises according to the embodiment shown, two parallel coiled coil springs 10, 11 which form a spring assembly. At a first end 12 of the energy store 3 are the coil springs 10, 11 on an adjustable fixed bearing 13 arranged. The camp 13 comprises a movable bearing part 14, on which the coil springs 10 . 11 releasably but firmly and are a control part 15 with an operating section 16, over which a user from the outside a position of the end 12 of the energy store 3 can adjust variably fixed position. This can advantageously a force effect of the energy storage 3 on the drawer 53 during the opening process of the drawer 53 be preset.

At a second end 17 of the energy store 3 are the associated ends of the coil springs 10 . 11 on a carriage-like movement element 18 attached. The carriage-like movement element 18 is via an associated guide contour 19 (hidden) on the base plate 1a movably guided in a direction of movement M1 and an opposite direction of movement M2 linearly.

The ejector 5 is in particular exclusively linearly movable or in the direction of movement of the moving element 18 movable in directions M1 and M2. This is a linear guide 20 at the base plate 1a formed, which on guide sections z. B. is tuned on one side of the ejector 5.

One from the ejector unit 1 bewirkter opening operation of the drawer 53 takes place exclusively via a direct operative connection of the energy storage 3 over the movement element moving in direction M1 18 on the ejector 5 instead of. This is the movement element 18 a stop element 26 formed, which is advantageously designed so that a disturbing for a user noise when hitting the moving member 18 to the ejector 5 in the opening process of the drawer 53 prevented or at least damped.

The coupling device 4 includes next to the cocking lever 30 , a lever 34 and a connection lever 35 , On the lever 34 is a parking section 34a formed, wherein the adjusting section 34a and the guide contour are matched.

The tension lever 30 is at a second end via a bearing pin 36 on the adjusting lever 34 hinged. The connecting element 35 is at a second end via a bearing pin 36th spaced trunnions 37 also on the adjusting lever 34 and at its first end via a further bearing pin 38 on the moving element 18 hinged. The adjusting lever 34 is at a first end via a bearing pin 39 of a pivot bearing 33 movable, in particular pivotable on the base plate 1a arranged. The journal 39 is preferably both on the base plate 1a as well as added to a cover component. The pivoting of the elements 30, 34, 35 and 6 takes place about a pivot axis which is perpendicular to one of the base plate 1a spanned level.

The lever 34 can when tensioning the energy storage 3 due to its design a force with a translation from the clamping lever 30 on the connecting element 35 transfer.

The transmission ratio is the one by the ratio of the distance between the journals 39 and 36 to the distance between the journals 39 and 37 on the lever 34 formed, on the other hand by the combined circular and linear movement of the clamping lever 30 and / or the connecting element 35 each other during the charging process of the energy storage 3 ,

The coupling device 4 can due to the above configuration, a force for tensioning the energy storage 3 from the ejector 5 via the clamping lever 30 and the lever 34 on the connecting element 35 and thus the energy storage 3 translated transmitted, in particular, the coupling device 4 reduces the ejector 5 applied force on the energy storage 3 , This means that when loading the energy accumulator 3, a user on the ejector 5 has a lower force than he would have to muster if he wanted to load the energy storage 3 without a reduction or directly the end 17 of the energy store 3 would pull in the direction of M2.

The tensioning of the energy storage 3 is completely finished, before, for example, a draw-in mechanism for power-assisted retraction of the drawer 53 in the fully closed closed position on the furniture body 51 takes effect. The automatic retraction is not part of the ejector unit 1 and integrated, for example, in the guide means 52 or the partial or full extension.

After tensioning the energy storage 3 is due to the further closing movement of the drawer 53 one with the drawer 53 moving driver 23 moved in the closing direction M2. The driver 23, for example, by a lateral projection on a drawer rail of the guide means 52 is formed, stands on the ejector 5 and takes it in the direction of M2 relative to the base plate 1a With. The for tensioning the energy storage 3 necessary operative connection or coupling between the ejector 5 or a part which can be swiveled on it (concealed) and a bearing journal 31 of the clamping lever 30 is released after the end of the clamping process, so that the clamping lever 30 then no longer from the ejector 5 is moved. With a further relatively short closing movement of the ejector after decoupling 5 in the closing direction M2, which can be done in particular by an automatic retraction (not shown), reaches the drawer 53 her completely closed on the furniture body 51 position. It is the basic position according to 3 reached.

Starting from a state of the furniture 50 when the drawer is closed 53 is the ejector unit 1 in a normal position or in a normal starting position according to 3 , wherein the energy storage 3 loaded and locked.

The 3 to 7 show the part of the ejector unit 1 with the coupling device 4 in normal operation to trigger the opening movement by pressing on the closed stationary furniture part or by pressing on the drawer front 55 in the closing direction M2. This operation or the associated mechanism is also referred to as a touch-latch.

Through the tensioned coil springs 10 . 11 is via the moving member 18 and the connecting element 35 the adjusting lever 34 is pressed in the clockwise direction or in the direction P1. At the same time is the locking lever 6 biased towards P2 pressed.

The guide contour 7 is to a flat top 6a of the locking lever 6 designed as a recess with different spatially aligned areas. The guide contour 7 includes a locking edge 8th with two angled edges (s. 6 ), in which in the basic position (s. 3 ), the adjusting portion 34a is present. The parking section 34a is an example of a base plate 1a directed bottom of the control lever 34 formed as a tab-shaped projecting projection 9, for example, as laterally and front cut free bend.

The normal operation according to touch-latch show the 4 to 7 , The normal triggering of the locking of the ejector unit 1 is carried out by pressing the drawer, not shown 53 in the closing direction M2 from the basic position 3 in the position according to 4 where the user is the drawer 53 maximum over a distance S1 of preferably about 0.8 to 1.2 millimeters in the direction of M2 presses (s. 3 ). Thereby one becomes with the drawer 53 connected drawer rail together with an existing driver 23 is also moved in the direction M2. With a paragraph 21 the ejector 5 that is attached to the motion element 18 is pending, becomes the moving element 18 also slightly shifted in the direction of M2, against the tensile force of the coil springs 10 . 11 ,

This will be the lever 34 pivoted slightly in the direction of P1 or in the direction of P3 and the projection 9 comes free from the locking edge 8th , At this moment, the locking lever pivots 6 slightly further towards P2 until one side of the ledge 9 on another edge 22 the leadership contour 9 is pending (s. 5 ). The locking lever 6 therefore can not continue to pivot in the direction of P2. Between the locking edge 8th and the edge 22 is an oblique or to the top 6a inclined ramp 25 available (s. 7 ), on which the projection 9 or its underside under the action of the tensile force of the coil springs 10 . 11 in the direction of P1 pivots and thus the locking 4 is canceled. The locking lever 6 is biased by its spring bias in the direction P2.

While the lead 9 the ramp 25 is moved over the lever 34 a little or z. B. raised in the tenth of a millimeter range, in particular according to a depth of the guide contour 7 to the top 6a , away from the base plate 1a What, for example, by a bearing clearance or a low elastic behavior of the control lever 34 is feasible.

After the lead 9 the leadership contour 7 has left or the projection outside the recessed guide contour 7 is the lead slides 9 on the flat or flat top 6a of the locking lever 6 (S. 6 ).

With the pivoting of the adjusting lever 34 in the direction of P1 and over the connecting element 35 the movement of the moving element 18 in the direction M1 is via the paragraph 21 also the ejector 5 and thus the driver 23 and the drawer 53 is ejected in the opening direction M1.

What happens when a user closes the drawer 35 Do not want to open, but the drawer 53 in the basic position according to 3 nevertheless pressed in closing direction M2? This is where the invention starts, which is based on the 8th to 14 is explained, wherein 8th of the 3 corresponds, so represents the basic position.

If a person is outside the furniture 50 For example, leaning and unconsciously the drawer front 55 maximum is pressed in the direction of M2. Then the forehead becomes 5a the ejector 5 to the abutment against the wall portion 27 or until touching the wall section 27 emotional.

In known ejector devices, the opening movement then triggers and the drawer is ejected, which is undesirable.

The ejector unit according to the invention 1 prevents this. The 9 to 14 illustrate the processes in the ejector unit 1 when pressing the closed drawer 53 in the direction of M2 via the Eindrückweg S2.

In a first leg of S2 is over the paragraph 21 , the stop element 26 and the connecting element 35 the adjusting lever 34 is pivoted in the direction P3, so that the projection 9 of the locking edge 8th moved away (s. 9 ). The adjusting lever 34 is in an intermediate position according to 9 , Then comes the further movement of the ejector 5 in the direction of M2 an actuator 28 on the ejector 5 in contact with the locking lever 6 so that it pivots against its spring action in the direction of P4 or clockwise. (S. 10 ).

With the end of the movement of the ejector 5 in the closing direction M2 according to 11 by the forehead 5a at the wall section 27 strikes, are the locking lever 6 and the lever 34 similar to a movement of vehicle windscreen wipers when pivoting outwards or away from each other in opposite directions moves. The locking lever 6 and the lever 34 reach a respective end position in their movement (s. 11 ). The projection 9 and the guide contour 7 are separated from each other.

Once the indenting force on the drawer 53 in the closing direction M2 is omitted, so if the leaning on the drawer front 55 person z. B. removed from the furniture is by the action of the tensile force of the tensioned or charged energy storage 3 on the movement element 18 the ejector 5 and thus the driver 23 including drawer 53 slightly offset in opening direction M1. About the connecting element 35 is also the lever 34 slightly swung back in the direction of P1.

Although the actuator 28 no longer on the locking lever 6 is present, the locking lever 6 initially prevented from swinging back in the direction of P2, because the lead 9 on another edge 29 the guide contour is present and thus the locking lever 6 in the direction P2 blocked (s. 12 ).

Only when the projection on the edge 29 until the end of the edge 29 has moved along or as soon as the projection 8th the end of the edge 29 has left (s. 13 ), snaps the next moment the locking lever 6 due to the locking lever 6 acting spring bias in the direction of P2. The lead 9 is in this moment or due to the edge 29 in the pivoting position according to the basic position of the ejector unit 1, so that the locking lever 6 at the locking edge 8th the leadership contour 7 comes into abutment and the locking of the ejector unit 1 with tensioned energy storage 3 is safely reached according to the basic position (s. 14 ). 14 corresponds to the basic position according to 3 , A disadvantageous opening of the drawer 53 under the effect of the energy store 3 does not occur according to the invention.
