Description

Device for moving a movable furniture part in an opening direction

Background

Various devices for moving a movable furniture part relative to a furniture body of a piece of furniture are known from the prior art. These devices are used in particular for moving movable furniture parts by means of guides in an opening direction and a closing direction opposite to the opening direction, wherein these devices have an energy store. Under the action of the force accumulator, the movable furniture part can be pushed out in the opening direction by the ejector, i.e. brought into the open position.

Disclosure of Invention

The object of the invention is to provide a device for moving a movable furniture part, in which the opening movement of the movable furniture part is improved.

This object is achieved by the features of the independent claims.

Advantageous and advantageous developments of the invention are given in the dependent claims.

The invention is based on a device for moving a movable furniture part in an opening direction relative to a furniture body of a piece of furniture, wherein the movable furniture part can be transported by means of a guide in the opening direction and in a closing direction opposite to the opening direction, wherein the device has a force accumulator and an ejector, such that, when the device is mounted on the piece of furniture, the movable furniture part can be moved by the ejector from a closing position in the opening direction into a first opening position by the ejector under the action of the loaded force accumulator during the opening process, in such a way that the force accumulator drives the ejector from its closing position in the opening direction during the opening movement of the ejector and can transmit the opening movement of the ejector to the movable furniture part.

The movable furniture part is preferably connected to the furniture body by a guide, wherein the guide moves the movable furniture part in the opening and closing direction. The movable furniture part is designed, for example, as a drawer, a furniture flap and/or a furniture door. In particular, the guide comprises a guide rail guide, such as a full or partial extension, or a pivoting guide, such as a furniture hinge. The guides include, for example, drawer rails and body rails. It is also conceivable that the guide has an intermediate rail in addition to the body rail and the drawer rail. The intermediate rail is preferably disposed between the body rail and the drawer rail.

The device according to the invention is preferably designed such that, in the state of the device on the piece of furniture, the at least partially unloaded (enterden) force accumulator is loaded again during the opening process or can be brought again into the clamped state in accordance with the closing movement of the movable furniture part relative to the furniture body. The force required for this purpose is applied, for example, by the user when the user moves the movable furniture part in the closing direction, for example by pressing it.

The means for triggering the opening movement of the ejector preferably have a so-called touch-lock function or a touch-lock arrangement. When the touch-latch function is integrated in the device, the movable furniture part which is closed on the furniture body and is normally held in the closed position is moved in the closing direction along a relatively short movement path of the movable furniture part by an externally induced movement of the movable furniture part, which describes the triggering process. During triggering, the energy store is unloaded, as a result of which the ejector is moved into the first open position. The movement of the movable furniture part or ejector in the closing direction is advantageously carried out by the user from the outside, for example by the user pressing against the front of the movable furniture part.

In the state in which the device is arranged on the piece of furniture, the closing direction of the ejector is preferably oriented parallel and in the same direction as the closing direction of the movable furniture part. Advantageously, the opening direction and the closing direction of the ejector are oriented opposite to each other. For example, the opening direction and the closing direction of the ejector are oriented parallel to each other.

The movable furniture part is moved out in the opening direction relative to the furniture body under the action of a force store of a device arranged on the furniture, over at least a partial distance of the movable furniture part on the furniture body according to the maximally provided opening path of the guide element up to a first opening position.

It is also advantageous if the movement of the ejector in the opening and closing direction is transmittable to a movable furniture part. The ejector is preferably configured in the form of a plate. The ejector preferably has a stop element which can interact with the movable furniture part. The stop element of the ejector preferably projects laterally on the device, so that during the closing movement in the closing direction, the movable furniture part only strikes the projecting stop element of the ejector and not the rest of the device.

The core of the invention is that the device has a latching member and a force unit acting on the latching member, wherein the latching member interacts with the ejector such that the latching member, under the force of the loaded force unit, brings the ejector in the opening direction from the first opening position to the second opening position. Advantageously, the latching member does not protrude or protrude on the outer side or profile of the device.

Advantageously, the ejector can be moved from the closed position into the first open position by the loaded accumulator and from the first open position into the second open position by the loaded force unit. During the closing movement of the movable furniture part or ejector from the second opening position into the closing position of the ejector in the closing direction, the charging process of the force accumulator and the force unit preferably takes place.

The force units may have different strengths or pulling forces. If the force unit is designed to be relatively weak, the movement of the movable furniture part is preferably guided by an operator or an accumulator. In the case of a more robust design of the force unit, the latter can be dimensioned sufficiently robust such that the movable furniture part can be moved in the opening direction only by means of the ejector by means of the force unit.

The movable furniture part is moved out in an opening direction relative to the furniture body under the action of a force unit of a device arranged on the furniture, over at least a partial distance of the movable furniture part on the furniture body, from the first open position into the second open position, depending on the opening path maximally provided by the guide.

In the assembled state, the first open position is horizontally spaced apart from the second open position in the opening direction.

The opening and closing direction of the ejector corresponds to the movement direction of the latch member, wherein the latch member moves the ejector in the opening direction by the action of the force unit. In the closing direction, the ejector preferably moves the latching member in the closing direction, whereby the force unit can be loaded.

Advantageously, the device has a guide with a guide rail, wherein the latching member is movable along the guide rail by means of the guide means.

The device preferably has a base plate on which the guide rails are formed. The guide rail is preferably present in the base plate sunk with respect to the main plane of the base plate. The main plane of the substrate preferably extends in the longitudinal direction or in the opening direction of the ejector and in a width direction, which extends perpendicular to the longitudinal direction. The cross section of the guide rail in the opening and closing direction is preferably configured in an L-shape. The longer leg of the L-shape is oriented in the opening and closing direction of the movable furniture part or ejector, and the shorter leg of the L-shape is preferably oriented perpendicular to the longer leg. Advantageously, the shorter side leg is oriented in the opposite direction to the ejector or sinks in the base plate compared to the longer side leg.

The longitudinal direction of the substrate is preferably oriented in the opening and closing direction of the ejector. Two completely separate guide rails are preferably provided, which are spaced apart in the width direction of the base plate, so that the latching member can be moved guided on both sides by the guide means. Another possibility is that only one single guide rail is present, wherein the guide part can then only be moved on one side while being supported on the guide rail. The latching member is advantageously positively controlled by the movement of the guide part along the guide rail.

Preferably, the guide element has an outer contour which moves along the guide rail, the outer contour preferably being convex or semicircular.

In the installed state of the device, the base plate or the device as a whole is preferably fixed in a stationary manner on the guide or the piece of furniture, in particular the drawer.

It is also advantageous if, in the mounted state of the device, a first end of the force unit is connected with the latching member and a second end of the force unit is connected with the device.

Preferably, the second end of the force unit, which is connected to the device, is fixedly arranged on the base plate. Preferably, a recess is present in the base plate, wherein the recess is designed to fit exactly with the second end of the force unit.

The second end of the force unit is preferably arranged further forward in the opening direction on the base plate than the first end of the force unit. The two ends of the force unit are preferably horizontally spaced from each other when the device is assembled. Advantageously, the second end of the force unit is fixed in position such that the movable latching member is pulled in the opening direction or in the direction of the second end of the force unit with the first end of the force unit.

It is also advantageous that in the closed position of the ejector the latch member is covered by the ejector from above in the mounted state.

Preferably, the latch member is completely covered by the ejector from above in the closed position. Preferably, the ejector prevents the latch member from moving in the opening direction due to the action of the force unit when the ejector covers the latch member. The latch member is advantageously covered by the ejector until the ejector has reached the first open position.

In the closed position of the ejector, the guide means of the latching member are advantageously arranged in a first guide region of the guide rail, wherein the first guide region is of a sunk configuration in the opposite direction of the ejector.

The first guide area is preferably the shorter leg of the L-shape. Advantageously, the first guide region is deeper in the depth direction of the substrate than the second guide region. Due to the design that the first guiding area is deeper than the second guiding area, the guiding means is arranged lower in the closed position than in the first open position, whereby the latch member can be covered by the ejector.

Preferably, the force unit is loaded when the guide member is arranged in the first guide region. The latching element is advantageously held in such a way that the guide part is arranged in the first guide region, so that the force unit cannot be unloaded in the opening direction.

Advantageously, the guide part of the latch member is movable along a second guide region of the guide rail in the opening and closing direction, wherein a longitudinal extension of the second guide region extends parallel to the direction of movement of the ejector in the opening and closing direction.

The second guide area is preferably the longer leg of the L-shape. The second guide region of the guide rail is preferably configured in the longitudinal direction of the base plate. Preferably, the direction of movement of the latch member is the same as the direction of movement of the ejector. The first guide region is preferably oriented perpendicularly to the second guide region. In the mounted state of the device, the first guide region is preferably oriented vertically and the second guide region is oriented horizontally. The first guide region, for example, transitions smoothly into the second guide region.

When the guide part is located in the second guide region, the force unit can be unloaded, whereby the latch member and the ejector or the movable furniture part are moved in the opening direction. The movement of the latch member along the second guide region corresponds, for example, to a movement of the ejector from the first open position to the second open position.

Advantageously, the latching member has a guide means, wherein the guide means is permanently arranged in the second guide region of the guide rail.

The guide means are designed, for example, as bolts and preferably project from the latching member. The guide means are preferably formed on both sides of the latch member. Advantageously, the latching member has two guide means which are supported for movement along guide rails spaced apart in the width direction. Preferably, the guide mechanism is suitably adapted for guided engagement in the guide rail. Advantageously, the guide means is guided in the second guide region by the entire opening and closing movement of the ejector, in particular with little play.

Preferably, in the closed position of the ejector, the guide member is arranged lower in a direction opposite to the ejector than the guide mechanism, which is arranged in the first guide area in the closed position. During the movement in the opening direction, the guide part passes from the sunken first guide region into the higher second guide region, whereby the latch member pivots in the direction of the ejector. Advantageously, the guide mechanism forms a pivot for the deflection or pivoting of the latch member. The pivot preferably extends perpendicularly to the opening and closing direction of the ejector. For example, the pivot passes through the center of the two circular faces of the cylindrical guide mechanism.

It is also advantageous if the guide rail is designed such that in the first open position the guide part of the latch member can be deflected in the direction of the ejector so that the hook section of the latch member engages with the ejector.

The hook section is advantageously arranged above the guide member in the direction of the ejector. Preferably, the hook section reaches the raised position in the direction of the ejector as a result of the guide part moving from the first guide region into the second guide region and as a result of the pivoting of the latching member.

Advantageously, in the longitudinal direction of the ejector, the end section of the ejector may be hooked back by the hook section. The end section of the ejector is preferably arranged on the edge of the ejector in the closing direction. The end section of the ejector is preferably arranged opposite a stop member of the ejector.

Advantageously, the latching member moves the ejector in the opening direction along the second guide region of the guide rail under the action of the loaded force unit.

By letting the guide means reach in the opening direction from the first guide region into the second guide region of the guide rail in a locking manner (arrestiert), the force unit can advantageously be relieved, whereby the latch member can be moved in the opening direction along the second guide region. Preferably, the guide part and the guide mechanism of the latch member are moved along the second guide region, whereby the movable furniture part or ejector is moved in the opening direction from the first open position to the second open position.

It is also advantageous if the ejector has a recess, in which there is space for the entire connecting section of the latching member.

Preferably, the hook section and the connecting section are spaced apart from each other in the longitudinal direction or opening direction of the ejector.

The connecting section is preferably permanently arranged in a recess of the ejector. The first end of the force unit can preferably be arranged on the connecting section. The connecting section has a precisely fitting receiving contour for the first end of the force unit.

Another possibility is that the substrate has a recess. Furthermore, when the substrate has a greater depth, the guide region may be configured deeper in the substrate, so that the recess in the ejector may be omitted.

Advantageously, the recess in the ejector is trough-shaped, wherein the connecting section of the latch member is movable along the length of the recess in the opening and closing direction of the ejector.

The connecting section is preferably movable along the length of the recess in the ejector when the ejector is moved from the closed position to the first open position and back.

Advantageously, the connecting section has a hook-shaped profile, wherein the hook-shaped profile interacts with an edge profile of the recess when the ejector is moved from the first open position to the second open position.

The connecting section preferably has a longitudinal contour which is oriented in the longitudinal direction of the ejector. Preferably, a hook-shaped contour is formed transversely to the longitudinal contour, which hook-shaped contour extends in the opposite direction to the ejector. The hook contour is preferably configured opposite the hook section.

The edge contour of the recess is preferably formed in the width direction of the recess, wherein the edge contour is preferably oriented in the direction of the closing direction.

Advantageously, the hook section rests against the end section of the ejector when the ejector is moved from the first open position into the second open position, wherein the hook profile of the connecting section rests against the edge profile of the recess during the opening movement. The hook-shaped contour of the connecting section and the edge contour of the recess are matched to one another in such a way that they can be brought into suitable engagement with one another, whereby force transmission is possible.

It is also advantageous if the edge profile of the ejector and the hook profile of the latching element can be coupled and decoupled, wherein during the movement in the opening direction the edge profile of the ejector moves the latching element by means of the hook profile, so that by the movement in the opening direction the latching element deflects or pivots the hook section by means of the guide means.

Since the edge profile of the ejector bears against the hook profile of the latching member, the latching member can be moved, for example briefly, in the opening direction by the ejector. As a result, the guide member moves along the guide rail, whereby the guide member enters the second guide area from the first guide area. In this case, the guide part and the hook section can be pivoted vertically upwards. During the pivoting movement in the direction of the ejector, the hook-shaped section hooks back the end contour of the ejector. When the guide part enters the second guide area, the force unit may be unloaded, whereby the latch member and the ejector are moved in the opening direction to the second opening position.

An advantageous embodiment of the invention is an item of furniture having a device for moving a movable furniture part relative to a furniture body according to any of the preceding designs. Preferably, there are two devices for moving movable furniture parts on the piece of furniture. For example, the piece of furniture comprises a furniture body and a movable furniture part movably arranged thereon. Advantageously, the device can be arranged on the furniture body and/or on the movable furniture part.

Detailed Description

Fig. 1 shows a piece of furniture 50 with a box-shaped furniture body 51 and a drawer 53, which is guided displaceably by a guide 52. Drawer 53 includes a drawer bottom 54, a drawer front 55, two opposing side walls 56, and a drawer rear wall 57.

For guiding the drawer 53, two guides 52 having the same function are respectively present between each side wall 56 of the drawer 53 and the associated body side wall 58. On the underside of the drawer bottom 54, a device 1, 2 according to the invention (shown in dashed lines) is arranged for moving or pushing out a furniture part designed as a drawer 53 in an opening direction M1.

The device 1 serves for the power-assisted ejection of a drawer 53 from a closed position relative to a furniture body 51 in the opening direction M1 of the drawer 53 along a partial distance of the opening movement of the drawer 53. The drawer 53 can be movably arranged on the furniture body 51 in the directions M1 and M2 by means of a guide 52, for example two identical partial or full extensions. The device 1 may alternatively be arranged on the furniture body 51 or on the guide 52 of the furniture 50.

The device mainly comprises a base plate 3, a force unit 4, a latch member 5, an ejector 6 and an accumulator 7 (see fig. 2). In the base plate 3, guide rails 8 are formed. A recess 9 is also provided in the base plate 3 for receiving a moving part 10, on which moving part 10 the energy store 7 is preferably received. The energy store 7 preferably comprises two helical springs 11, 12, which are each fastened at one end to the moving part 10. The other ends of the helical springs 11, 12 are advantageously connected to a support part 13, wherein the length of the tensioned helical springs 11, 12 can be adjusted by means of an operating section 14. On the moving part 10, an elastic rod 15 is arranged, which is preferably guided within a cardioid curve 16 formed in the base plate 3. Furthermore, the elastic rod 15 is movable along a guide runner 17 of the ejector 6. During the movement of the spring rod 15 along the guide slot 17 in the ejector 6 and/or the cardioid section 16 in the base plate 3, the synchronization plate 18 can also move together. The synchronizing plate 18 is connected to the base plate 3 by means of springs 19.

The substrate 3 is covered by a covering member 20, wherein the covering member 20 has a control cover 21. The cover part 20 and the control cover 21 may also be constructed in one piece. The control cover 21 preferably has a further cardioid section (not shown), which in the assembled state is preferably formed in the base plate 3 mirror-symmetrically to the cardioid section 16.

The guide rail 8 is designed in the base plate 3 in order to move the latching member 5 along the guide rail 8. The guide 8 preferably has two separately designed guide rails 8 in the width direction of the base plate, which is oriented perpendicularly to the opening and closing movement of the ejector 6. The guide rail 8 can be divided into two guide areas 22, 23, preferably into exactly two guide areas. The first guide region 22 is designed to be recessed in the substrate 3 in the opposite direction with respect to the ejector 6. The second guide area 23 preferably extends in the opening direction P1 as well as in the closing direction P2 of the ejector 6. The two guide regions 22, 23 are formed, for example, in an L-shape, the longer leg forming the second guide region 23 and the shorter leg forming the first guide region 22.

In fig. 3, a receptacle for the second end of the force unit 4 in the base plate 3 can be seen. The first end of the force unit 4 is connected with the connecting section 24 of the latching member 5 (see fig. 4). The latching member 5 also has a guide means 25 which is preferably permanently movable in the second guide region 23 of the guide rail 8. There is a guide means 25 protruding at the latch member 5 and preferably cylindrical or bolt-like. There are preferably guide means 25 on both sides of the latching member 5, which are movable along the width-wise spaced apart guide rails 8. Advantageously, the guide means 25 can be moved supported along the second guide region 23 of the guide rail 8. The latching member 5 also has a guide part 26 which moves from the first guide region 22 into the second guide region 23 during the opening movement of the ejector 6. As a result, the hook section 27 of the latching member 5, which is located above the guide part 26 in the direction of the ejector 6, can be pivoted in the direction of the ejector 6. The latch member 5 also has a hook-shaped profile 28 capable of interacting with the ejector 6. The hook-shaped profile 28 is preferably oriented transversely to the opening and closing direction of the ejector 6.

The ejector 6 has a recess 29 on a bottom surface directed in the direction of the substrate 3. The recess 29 is preferably groove-shaped, wherein the longitudinal extension L of the recess 29 is directed in the opening and closing direction of the ejector 6. The connecting section 24 of the latching member 5 is preferably received in the recess 29. The recess 29 has a surface formed in the width direction and height with an edge profile 30 that can be coupled and decoupled with the hook profile 28 of the latch member 5.

A stop element 31 is formed on the ejector 6, which stop element interacts with the drawer 53. During the opening movement, the ejector 6 moves the drawer 53 in the opening direction P1 by means of the stop element 31, using the force of the loaded force unit 4 and/or the force accumulator 7. During the closing movement P2, the drawer 53 presses against the stop element 31 of the ejector 6, thereby loading the energy store 7 and the force unit 4.

In fig. 6, the device is shown in the closed position. For clarity, the cover portion 20 is not shown in fig. 6-8. In addition, the control cover 21 is not shown in fig. 6. In fig. 7, 8, 10, 11, 13 and 14, only the ejector 6 and the latching member 5 are shown in section in order to better see the arrangement of the latching member 5 in the guide rail 8.

As can be seen in fig. 6 to 8, the latching member 5 is covered from above by the ejector 6 in the closed position. The connecting section 24 of the latching member 5 is received in a recess 29 of the ejector 6, wherein an edge contour 30 of the recess 29 does not interact with the hook contour 28 of the latching member 5. The guide means 26 of the latching member 5 in the closed position are in the first guide region 22, so that the force unit 4 is maximally tensioned. The guide means 25 are supported on the guide rail 8 of the second guide area 23.

The spring lever 15 is arranged in the bow of the cardioid curve 16, wherein the spring lever 15 cannot move in the opening direction P1 because the synchronization plate 18 blocks this movement (see fig. 6). By pushing the drawer 53 in the closing direction M2, the ejector 6 is moved in the closing direction P2 along with the moving member 10. By means of the moving part 10, the spring lever 15 is also moved in the closing direction P2, whereby the spring lever 15 is no longer blocked by the synchronization plate 18. The accumulator 7 is therefore relieved of load and the elastic rod 15 moves along the cardioid curve in the opening direction P1. When the elastic rod 15 moves in the opening direction P1, the synchronizing plate 18 and the ejector 6 also move in the opening direction P1 until the first open position is reached (see fig. 9). In the first open position, the accumulator 7 is unloaded.

In fig. 10 and 11, the guide part 26 of the latching member 5 is still in the first guide region 22 of the guide rail 8, so that the hook section 27 has not yet been deflected in the direction of the ejector 6. By the edge profile 30 of the recess hitting the hook profile 28 of the latching member 5, the latching member 5 is moved in the opening direction, whereby the guide part 26 is moved along the guide rail 8 into the second guide area 23. The latching member 5 can pivot about a guide means 25 which rests on the guide rail 8 in the second guide region 23. When the latching member 5 is pivoted, the hook section 27 can be deflected upwards in the direction of the ejector 6, wherein the hook section 27 barbs the end profile 32 of the ejector 6. As soon as the guide part 26 of the latching member 5 reaches the second guide region 23 of the guide rail 8, the force unit 4 can be unloaded. Thereby causing the latch member 5 to move in the opening direction P1. Since the hook section 27 of the latch member 5 barbs the ejector 6, the ejector 6 is also moved in the opening direction P1 until the second opening position is reached (see fig. 12 to 14). The drawer 53 is moved in the opening direction P1 by the stopper member 31 of the ejector 6.

In the second open position, the force unit 4 is unloaded. In fig. 14 it can be seen that the edge profile 30 of the recess 29 rests on the hook profile 28 of the latching member 5. Furthermore, the guide means 25 and the guide part 26 are located in the second guide region 23 of the guide rail 8, wherein the guide means 25 is horizontally spaced apart from the guide part 26. The guide mechanism 25 is further forward in the opening direction P1 than the guide member 26.

During the opening movement from the first open position (see fig. 9) to the second open position (see fig. 12), the elastic rod 15 first moves along the first rectilinear area 33 of the guide chute 17 of the ejector 6. The elastic rod 15 is fixedly arranged in a position on the cardioid curve 16. With further movement in the opening direction P1, the spring lever 15 is moved to the right or in the direction of the force unit 4 by the lateral region 34 of the guide runner 17 and then along the second linear region 35. The spring rod 15 thus reaches the right-hand section of the cardioid curve 16 (see fig. 12), and the synchronization plate 18 can be pulled back into the starting position by the spring 19. During the closing movement of the ejector 6 in the closing direction P2, the resilient lever 15 first moves along the second rectilinear area 35 of the guide chute 17 until the resilient lever 15 abuts on the transition between the second rectilinear area 35 and the lateral area 34. When the spring lever 15 abuts against the transition, then, in a further closing movement of the ejector 6, the spring lever 15 and thus also the moving part 10 can be moved in the closing direction P2 by means of the energy store 7, wherein the energy store 7 is loaded. Here, the elastic rod 15 is guided along a region 36 extending straight to the right of the cardioid curve 16 up to the end of this region, and then the elastic rod 15 follows the cardioid curve 16 and moves to the left in the direction of the spring 19. The spring lever 15 therefore also reaches into the first linear region 33 of the guide link 17. The spring lever 15 is locked in the heart curve 16, whereby the spring lever 15 moves along the first linear region 33 during a further closing movement of the ejector 6. In a further closing movement of the expeller 6, the closed position is reached (see fig. 6).

When the ejector 6 is moved in the closing direction P2, the force unit 4 is loaded directly by the hook section 27 abutting against the end contour 32 of the ejector 6. The guide means 25 and the guide part 26 can be moved along the second guide region 23 of the guide rail 8 until the guide part 26 reaches the first guide region 22 and pivots downward. In this way, the hook section 27 of the latching member 5 no longer abuts against the end contour 32 of the ejector 6, so that the ejector 6 can be moved relative to the latching member 5 in the closing direction P2. Here, the connecting section 24 of the latching member 5 moves along the recess 29 of the ejector 6.
