DESCRIPTION

Device for moving a part of mobile furniture

State of the art

Devices for moving a movable piece of furniture are known, in particular devices that can, for example, be attached to guide means for guided movement of the movable piece of furniture. The known devices are suitable for moving a movable piece of furniture by means of a force accumulator in the opening and/or closing direction relative to the furniture body, after the device has been released with the force accumulator charged. One such device is described in application DE 102016 113043 A1.

Object and advantages of the invention

The object of the present invention is to improve a device for moving a mobile piece of furniture, in particular with regard to an unwanted disengagement of the device.

This object is solved by independent claims.

Advantageous and convenient variants of the invention are indicated in the dependent claims.

The invention starts with a device for moving a furniture part in an opening direction relative to a furniture body of a piece of furniture, the movable furniture part being able to be brought by means of guide means into the opening direction and into a closing direction opposite to the opening direction, the device having a force accumulator and an ejector, such that with the device mounted on the furniture, the movable furniture part can be moved from the closing position in the opening direction under the influence of the force accumulator, in an opening process, the force accumulator actuating the ejector from a closing position of the ejector in an opening movement of the ejector in an opening direction, and the opening movement of the ejector can be transmitted to the movable furniture part, in the case of a closing movement of the ejector from an opening position of the ejector in a closing direction, a charging process of the force accumulator is enabled, device has a locking arrangement with a release element, where the locking arrangement, in a locked position of the locking arrangement, is designed to hold the force accumulator in the charged state, where the ejector, upon closing movement in the closing direction, can be moved from the closed position to a release position of the ejector, where the closing movement of the ejector can be transmitted to the release element, so that the release element can be brought from a rest position to a release position, where in the release position of the release element, the force accumulator is present unlocked, where the device has a guide slide, where a release part is present guided in the guide slide, where the release part is connected to the ejector, so that the movement of the ejector in the opening and closing direction can be transmitted to the release part, where a release element is arranged on the guide slide delay, where the delay element is designed to delay in time a movement of the release part, from the closed position to the release position, by means of friction.

The movable furniture part, preferably via guide means, is connected to the furniture body, where the guide means can displace the movable furniture part in the opening and closing direction. The movable furniture part, for example, is designed as a linearly moving drawer, a pivoting furniture lid, and/or a pivoting furniture door. The guide means in particular comprise a rail guide, such as a full or partial extension, or a pivoting guide, such as a furniture hinge. The guide means, for example, comprise a drawer rail and a body rail. It is also possible for the guide means, in addition to the body rail and the drawer rail, to have a center rail.

According to the invention, the release part is connected to the ejector, so that the movement of the ejector in the opening and closing direction can be transmitted to the release part.

Preferably, the device for initiating the opening movement of the ejector has a so-called touch-latch function or a touch-latch arrangement. In the touch-latch function integrated in the device, the movable furniture part, closed in the furniture body and generally held in the closed position, moves a relatively short distance from the movable furniture part in the closing direction, triggered from the outside, which describes the release process. During the release process, preferably, the ejector or the release part comes into contact with the release element of the locking arrangement by moving the movable furniture part in the closing direction. The release element, via the release part, moves to the release position, where the force accumulator is unlocked, so that the opening movement of the movable furniture part and the ejector takes place, assisted by force, via the force accumulator. The movement of the movable furniture part and the ejector in the closing direction advantageously occurs from the outside, by the user, for example, who presses a front part of the movable furniture part.

The device according to the invention is preferably designed such that, in the arranged state of the device in the furniture, upon closing movement of the movable furniture part relative to the furniture body, the force accumulator, which is at least partially charged during the opening process, is recharged and can be brought back into a tensioned state. The force input required for this purpose is, for example, applied by the user when the user moves, for example by pressing, the movable furniture part in the closing direction. The movement of the movable furniture part in the closing direction can optionally be facilitated by an automatic retraction system.

Preferably, the closing direction of the ejector, when the device is arranged in the furniture, is parallel to and aligned with the closing direction of the movable furniture part. It is also possible for the closing direction of the ejector, when the device is arranged in the furniture, to be parallel to and aligned with the opening direction of the movable furniture part. Advantageously, the opening direction and the closing direction of the ejector are oriented opposite each other. For example, the opening direction and the closing direction of the ejector are oriented parallel to each other. Advantageously, in the closed position of the movable furniture part, a front element of the movable furniture part, for example a drawer front, is spaced apart from a front side of the furniture body. For example, in the closed position, a space is formed between the front element of the movable furniture part and the front side of the furniture body, which forms a natural stop for the movable furniture part.

An outward movement of the movable furniture part from the closed position in the opening direction relative to the furniture body, by means of the force accumulator of the device arranged in the furniture, takes place over at least a partial section of an opening path of the movable furniture part in the body, which is maximally proportioned according to the guide means. The ejector can preferably be guided along a guide path, the guide path being connected to the guide slide. Between the guide path and the guide slide, for example, a locking element is provided, the locking element being able to be overcome only by an effort from the release portion. Preferably, the locking element tilts the release portion toward a guide section of the guide slide. In particular, a blocking of the movement of the ejector from the closed position to an open position can be eliminated such that the release part moves, in particular rotates, in a direction transversely to an opening and/or closing movement of the ejector.

The guide slide is preferably designed in the form of a loop. The release portion of the guide slide can preferably be guided, for example, from a closed position to an unlocked position.

The central idea of the invention lies in the fact that a delay element is arranged on the guide slide, where the delay element is designed to delay in time a movement of the release part, from the closed position to the release position, by means of friction.

Preferably, the release portion is designed as a resilient element. For example, the release portion is designed resiliently. Furthermore, the release portion may be integral with the ejector. For example, the release portion is coupled, in particular connected, to the ejector via a resilient element. For example, the ejector, the resilient element, and the release portion are integral or integral. This comparatively simplifies and/or facilitates the production of the device parts.

Preferably, the guide slide is recessed relative to a flat surface of the device, with the outer edges of the guide slide preferably being bounded by side walls. A limiting element, for example, triangular in shape, is preferably provided in the center of the guide slide.

Preferably, the delay element is formed in the recessed area of the guide slide, for example between the side wall and the limiting element. Advantageously, the delay element is arranged such that at least a portion of the release portion must pass through the delay element. Preferably, the speed of travel of the release portion is reduced or braked by the delay element when the release portion comes into contact with the delay element.

Advantageously, the movement of the release part from the closed position to the release position can be delayed in time, so that in the event of a closing movement of the movable furniture part, the release element is not accidentally activated or the locking of the force accumulator is removed, for example by the user.

It is considered advantageous if the release part is arranged movably in the ejector. It is considered advantageous if the release part is pivotally arranged in the ejector. It is also possible for the release part to be arranged in the ejector so that it can move linearly or displaceably relative to the ejector. Preferably, the release part is movable in a direction transverse to an opening and/or closing direction of the ejector, relative to the ejector. For example, a pivot axis of the release part is oriented transversely, in particular perpendicularly, to an opening and/or closing direction of the ejector.

Advantageously, the release part can pivot on the ejector by moving along the guide slide. Preferably, the release part can be tilted in the closing direction, toward the force accumulator. In the opening direction, the release part can preferably be displaced along the guide slide in the opening direction of the ejector or the movable housing part.

Similarly, it is advantageous if the device comprises a base plate, where the guide slide is formed on the base plate.

The base plate is preferably arranged in a fixed position; for example, the base plate can be connected to the guide means or to the movable furniture part. The guide slide is preferably recessed into the base plate relative to a flat surface of the base plate. The guide slide is preferably limited by side walls of the base plate. Preferably, the limiting element, which is centrally arranged on the guide slide, forms part of the base plate.

Furthermore, advantageously, the guide track is made in the base plate, in particular recessed.

It is considered advantageous if the delay element is made of an elastic material.

Advantageously, the delay element is made of an elastomer, such as rubber. The delay element is preferably designed as a separate component.

The delay element preferably has a stop for limiting the movement of the release part in the closing direction by means of the stop. Preferably, the stop moderates the movement of the release part in the closing direction.

It is considered advantageous that in the assembled state of the device, the delay element, along the direction of travel of the ejector, is trapezoidal in section.

Advantageously, the delay element is designed so that it has two bevels. The bevels are preferably oriented obliquely or transversely to the opening and closing direction of the ejector. Furthermore, the bevels are preferably connected by straight sections, with the straight section arranged on the base plate being longer than the upper straight section.

Preferably, the delay element has a first bevel extending downward in the opening direction. With the first bevel, the release portion can be displaced along the closing direction, with the delay element being pressed downward. It is advantageous if the release portion has a projection, the projection being guided from the closing position to the release position and back on the guide slide.

Advantageously, the projection is provided projecting from the release portion. Preferably, the projection projects outward from an external surface of the release portion. Preferably, the projection is formed in the direction of the base plate on the release portion, such that the projection is guided in the guide slide. The release portion can be tilted or pivoted relative to the ejector by shifting the projection in the guide slide.

The protrusion on the release part, for example, is a pivot or a pin.

It is also advantageous that during the closing movement of the ejector in the closing direction, a lower side of the release part comes into contact with the delay element, so that the movement of the release part from the closing position to the actuating position by means of the friction of the lower side on the delay element causes a delay of the release part.

The underside of the release part is preferably arranged in the direction of the base plate or the guide slide. During the guiding of the projection in the guide slide, advantageously, the underside of the release part comes into contact with the delay element, the underside moving along the surface of the delay element. Because the delay element, for example, is an elastomer, the frictional resistance between the delay element and the underside is relatively high. Advantageously, the movement of the release part toward the release position is delayed in time by the delay element.

Advantageously, the delay element can be deformed by the underside of the release part.

Preferably, the elastic delay element can be deformed by a force applied from the underside of the release portion. Advantageously, the delay element can be pressed toward the base plate or the recessed guide slide. Advantageously, the pressed delay element lies approximately in the same plane as the recessed guide slide.

It is also possible for grooves to be formed in the base plate around three sides of the delay element, for example a square one, so that the delay element can be pressed in a plane below the base plate and in the opposite direction to the release portion. In this way, one side of the delay element is permanently connected to the base plate. Preferably, the side connected to the delay element on the base plate faces the release portion and the locking arrangement.

Similarly, it is advantageous if the device has a spring element, the spring element being present such that the spring element, when the release part is moved in the closing direction, presses the release part into the release position.

The spring element is preferably arranged between the release element and the locking arrangement on the base plate. Alternatively, the spring element can be arranged in the ejector. The spring element is advantageously designed as a leaf spring. The spring element preferably has a straight section, which is advantageously firmly connected to the base plate. After the straight section, for example, there is a section that is arranged at an angle to the straight section, and after the angled section, there is, for example, another angled section. The two angled sections preferably form a shape resembling a gable roof. The point between the angled sections and the front of the gable roof preferably faces the direction of the release element. The other angled section preferably faces the direction of the guide slide.

When the release part is displaced, the release part first comes into contact with the other corner section of the spring element. When the release part is displaced further in the closing direction, the release part preferably reaches the tip between the corner sections, whereby the spring element is subjected to a force in the opposite direction to the release element. By applying force from the spring element, the release part can be pressed toward the release position, as well as toward the release element.

It is advantageous if the guide slide is designed as a closed loop, where the guide slide has guide sections, where in a first guide section the release part can be displaced along the closing direction and in a second guide section along the opening direction.

Advantageously, the release portion can pivot relative to the ejector in the closing direction, with the first guide section oriented transversely to the ejector's travel direction, in the opening and closing directions. The movement of the release portion in the closing direction begins in the starting area of the first guide section and ends in the end area of the second guide section.

The movement of the release part in the opening direction preferably begins in the starting area of the second guide section and ends in the end area of the second guide section. In the release position of the release part, for example, the projection of the release part is located in the starting area of the second guide section.

Preferably, the loop is closed in the starting area of the first guide section and in the end section of the second guide section. Advantageously, in the opening direction, the guide track is located next to the guide slide, in which the ejector is guided. Advantageously, between the first and second guide sections, there is a third guide section connecting the first and second guide sections, where the delay element is arranged in the third guide section.

Advantageously, the third guide section starts at the end section of the first guide section and ends at the start area of the second guide section.

Preferably, the third guide section is formed in the direction of the release element.

It is considered advantageous if the release part can be brought into a safety position, where in the safety position the release part cannot disengage the release element, just as it cannot bring the release element into the release position.

This prevents, in particular, the accidental initiation of an opening process by the action of the force accumulator after the loading process has been completed by another, particularly continuously continuing, closing movement of the movable furniture part. This prevents, for example, a comparatively rapid or intensive movement of the movable furniture part in the closing direction, for example due to a further movement of the movable furniture part due to inertia of the movable furniture part or due to a strong push of the movable furniture part, the force accumulator from disengaging and the movable furniture part from being ejected again by the force accumulator.

More preferably, the release portion reaches the safety position when the movable cabinet portion or the ejector is pressed in the closing direction, for example by a user. If no force is exerted on the movable cabinet portion in the closing direction, the release portion preferably reaches the release position directly.

In the safety position, the release part can be moved further in the closing direction, so that, for example, the release part is located at the stop of the delay element. In the safety position, the release part preferably lies on a lateral surface of the release element, so that the release element cannot be disengaged by the release part. This prevents accidental ejection of the ejector in the opening direction. The release part can preferably be pressed against the lateral surface of the release element by means of the spring element.

It is also advantageous if the release element has a slide guide, whereby the release part, in the case of a movement from the safety position to the release position, is present at least in some sections guided by the slide guide of the release element.

The slide guide is designed, for example, in the form of a ramp. Advantageously, the slide guide on the release element is shaped laterally in the direction of the spring element.

Advantageously, the device is designed such that the release part, in the event of a displacement of the release part in the opening direction, is guided from its safety position to its release position by means of the slide guide.

Another possibility is for the device to comprise a force unit, where the force unit moves the release part from the safety position to the release position.

Preferably, the force unit is a spring. The force unit is preferably part of a damping element. Advantageously, a movement of the ejector from the closed position to the disengaged position is moderated and/or braked by the damping element. Preferably, the ejector acts directly on the damping element. The force unit, for example, is arranged in a cylinder of the damping element. The damping element preferably has a piston, where a piston rod is arranged in the direction of the guide slide, such that the ejector is positioned adjacent to the piston rod in the disengaged position of the disengaging part.

The piston rod, preferably in the safety position, is moved in the closing direction by the ejector, thereby loading the power unit. When the forces on the ejector in the closing direction are removed, the power unit is relieved, so that the ejector, as well as the release part, are moved to the release position by the power unit.

Advantageously, the force unit is loaded by force from the ejector into the safety position of the release part in the opening direction, where the force unit can be discharged when no force is exerted on the movable furniture part, as well as the ejector in the closing direction. By discharging the force unit, the release part can be moved from the safety position to the release position, where in the event of such displacement, the release part can be displaced along the slide guide of the release element.

An advantageous embodiment of the invention consists of a piece of furniture with a device according to one of the embodiments described above. For example, the piece of furniture comprises a furniture body and a movable furniture part, movably arranged therein. Advantageously, the device is designed so that it can be movably arranged in the furniture body and/or in the movable furniture part. Preferably, the movable furniture part is a drawer with guide means, preferably with full or partial extension.

1 shows a piece of furniture 50 with a box-shaped cabinet body 51 and a drawer 53 movably guided by guide means 52. The drawer 53 comprises a drawer floor 54, a drawer front 55, two opposite side walls 56 and a drawer rear wall 57. For guiding the drawer 53, two similarly acting guide means 52 are present, respectively between each side wall 56 of the drawer 53 and a corresponding body-side wall 58. On an underside of the drawer floor 54, a device 1, 2 according to the invention is arranged (shown in dashed lines) for displacing or ejecting the drawer-designed furniture part 53 in the opening direction M1.

The device 1 is used for the force-assisted ejection of the drawer 53, over a part of an 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 mounted so as to be movable in the directions M1 and M2, in the furniture body 51, by means of guide means 52, for example two partial or complete extensions of the same kind. The device 1, alternatively, may be arranged on the furniture body 51 or on the guide means 52 of the furniture 50.

The device 1 comprises, among other things, a base plate 3, a force accumulator 4, a coupling device 5, an ejector 6, a locking arrangement 7, and a delay element 44 (see Figure 2). In the ejector 6, a release part 8 may be arranged movably. For example, the release part 8 is designed in the form of a pressure piece. For example, the locking arrangement 7 comprises a release element 9. For example, the release part 9 is designed as a trigger. It is also possible for a damping element 11 to be present. For example, the damping element 11 comprises a piston 45 and a force unit 12, in particular a spring. Advantageously, by moving the piston 45, a force can be applied to the force unit 12.

Advantageously, the device 1 comprises a spring element 26, in particular in the form of a leaf spring. The spring element 26 preferably has an end 27, which is preferably connected to the base plate 3, in particular is arranged in a fixed position. After the end 27, there is a straight section of the spring element. Following the straight section, there are preferably two corner sections that form a gabled roof shape. Advantageously, a guide track 10 and a guide slide 25 are formed on the base plate 3. The delay element 44 is arranged on the guide slide 25. The delay element 44 is preferably made of an elastomer and has a stop 46. By means of the stop 46, the displacement of the release part 8 in the closing direction can be moderated. The guide slide 25 is limited on the outer sides by the side wall 47 of the base plate 3, and in the center by a limiting element 48.

A housing of the device 1 comprises the base plate 3 and a cover component, which is not shown. The device 1, via the housing or via the cover component and/or the base plate 3, can be arranged on the underside of the drawer floor 54 and/or on the guide means 52.

On the base plate 3, retaining sections, guide contours, stop elements and/or receiving sections are formed for coupling the individual components of the device 1.

Advantageously, the force accumulator 4 according to the exemplary embodiment shown comprises two parallel-arranged helical springs 13, 14 of the same type, which form a spring package. For example, at a first end of the force accumulator 4, the helical springs 13, 14 are arranged in an adjustable, stationary support 15. Advantageously, the stationary support 15 comprises a movable support part 16 in which the helical springs 13, 14 are removably but firmly housed, and an adjustment part 17 with a control section 18, by means of which a user, from the outside, can adjust a position of the end of the force accumulator 4 in a position-variable manner. Thanks to this, advantageously, a force effect of the force accumulator 4 on the drawer 53 can be pre-regulated during the opening process of the drawer 53.

Preferably, at a second end of the force accumulator 4, the corresponding ends of the helical springs 13, 14 are fixed to a carriage-like displacement element 19. The carriage-like displacement element 19 is guided linearly so as to be movable in a displacement direction P1 and in an opposite displacement direction P2 by means of a corresponding guide contour on the base plate 3.

The displacement directions P1 and P2 of the displacement element 19 extend parallel to the opening direction M1 of the drawer 53 and to a closing direction M2 opposite thereto. If the device 1 is arranged in a fixed position on the furniture body 51 and/or on a stationary part of the guide means 52, the opening direction M1 of the drawer 53 corresponds to the direction p1, and the closing direction M2 of the drawer 53 corresponds to the direction P2.

For example, the ejector 6 can move exclusively linearly or parallel to the direction of travel of the displacement element 19, in the directions P2 and P2, linearly, from one side to the other. For this purpose, the guide track 10 is formed on the base plate 3, which is adapted to a guide element, for example on one side of the ejector 6. Advantageously, an opening process of the drawer 53, triggered by the device 1, takes place exclusively by a direct interaction of the force accumulator 4, by means of the displacement element 19 moving in the direction P2, in the ejector 6. For this purpose, a stop element 20 is formed on the displacement element 19, which advantageously is designed to be elastic and, thus, prevents or at least attenuates a noise, annoying for the user, in the event that the displacement element 19 possibly comes into contact with the ejector 6 during the opening process of the drawer 53.

Preferably, the coupling device 5, together with a clamping lever 21, comprises an adjusting lever 22 and a connecting lever 23. The clamping lever 21 is pivoted at a second end to the adjusting lever 22 by means of a pin. The connecting lever 23 is pivoted at a second end to the adjusting lever 22 by means of a further pin spaced apart from the pin, and is pivoted at its first end to the displacement element 19 by means of a further pin. The adjusting lever 22 is displaceable at a first end by means of a further pin, in particular it is pivotably arranged on the base plate 3, the pin preferably being received both in the base plate 3 and in the cover component (not shown). The adjusting lever 22 is advantageously pivotally and/or rotatably mounted about an axis of rotation for loading the force accumulator 4.

The adjusting lever 22, when the force accumulator 4 is tensioned, due to its configuration, can transmit a force with a multiplication from the clamping lever 21 to the connecting lever 23. The transmission ratio, on the one hand, is formed by the relationship of the distance of the pivots on the adjusting lever 22, on the other hand, by the combined circular and linear displacement of the clamping lever 21 and/or the connecting lever 23 relative to each other, during the charging process of the force accumulator 4.

The coupling device 5, due to the aforementioned configuration, can transmit a multiplied force for tensioning the force accumulator 4 from the ejector 6, via the clamping lever 21 and the adjustment lever 22, to the connecting lever 23 and, thereby, the force accumulator 4, in particular, the coupling device 5 reduces the force exerted by the ejector 6, on the force accumulator 4. This means that when loading the force accumulator 4, a user, on the ejector 6, has applied a smaller force than would have to be applied if he wanted to load the force accumulator 4 without a reduction. Advantageously, the tensioning of the force accumulator 4 is completely completed, for example, before a retraction system of the device 1 (not shown) acts for the force-assisted retraction of the drawer 53 into the fully closed position in the furniture body 51. The retraction system, for example, is not part of the device 1.

In a closing movement of the drawer 53, the ejector 6, starting from an open position, moves in the closing direction P2 by means of a drive element (not shown), which in the embodiment described in particular is present in a fixed position on the furniture body 51.

In Figures 2, 3, and 4, the force accumulator 4 is shown in a loaded position. The force accumulator 4 is held in the loaded state by engaging the displacement element 19 with the locking arrangement 7. In this position, the ejector 6 is, for example, decoupled from the locking arrangement 7. In Figure 2, the ejector 6 is shown in a closed position.

Advantageously, the release part 8 is mounted rotatably on the ejector 6. For example, the ejector 6 comprises a limiting contour 29, which limits a rotational displacement of the release part 8 relative to the ejector 6.

Preferably, the release part 8 comprises a projection 30 which, in the arranged state of the release part 8 on the base plate 3, engages the guide slide 25. For example, the projection 30 is designed in the form of a pin or a bolt. It is possible for the projection 30 to project from a bottom side 32 of the release part 8. Advantageously, the guide slide 25 is designed such that, in the event of a movement of the ejector 6 from the closed position to a release position, in the closing direction or vice versa, a displacement of the release part 8 can take place relative to the ejector 6.

The release part 8, for example, is mounted movably at a first end 33, in particular rotatably, in the ejector 6. Advantageously, the release part 8 comprises a limiting element 34 at the first end 33, for example in the form of a pin. For example, the limiting element 34, in the arranged state of the release part 8 in the ejector 6, engages in the limiting contour 29, such that a rotational displacement of the release part 8 relative to the ejector 6 is limited by the interaction of the limiting contour 29 with the limiting element 34.

Preferably, the release part 8 is present in the form of a plate, with two opposite large side surfaces and two opposite narrow side surfaces, where at one end of the side surfaces the first end 33 of the release part 8 is present. Opposite the first end 33, the release part 8 has a second end 35. Advantageously, the release part 8 at the second end 35 comprises a stop surface 38, by means of which the release part 8, in the release position, can interact with the release element 9.

The release portion 8 is shown in Figures 3 and 9 in a safety position. Advantageously, the ejector 6, with one end 31, is in contact with the piston 45 of the damping element 11. For example, the release portion 8, in the safety position, as opposed to the release position, is in a rotated, offset position relative to the ejector 6. In Figures 4 and 10, the release portion 8 is shown in the release position. For example, the release portion 8, according to the position in Figures 4 and 10, with its abutment surface 38, on a release surface 39, abuts against the release element 9.

Preferably, a slide guide 28 is provided on the release element 9. The slide guide 28 is, for example, designed as a bevel, for example in the form of a ramp on the release element 9. For example, the slide guide 28 ends at one end of the release element 9 in the release surface 39.

6 shows that the guide slide 25 may comprise a locking element 40. The locking element 40, for example, is designed as a narrowing which forms a passage between the guide track 10 and the guide slide 25. For example, the release part 8, with its projection 30, depending on the position of the ejector 6, is present guided relatively with respect to the base plate 3 in the guide track 10 or in the guide slide 25.

A sequence of movement of the ejector 6 and the release part 8 is described below, starting from an open position of the ejector 6, in the closing direction.

Starting from an open position of the ejector 6 (not shown), the ejector 6 moves in direction P2 in the case of a closing movement, for example by a user closing the drawer 53, in the arranged state of the device 1 in the furniture 50. During the closing movement, the ejector 6 reaches the closing position according to Figure 2.

Due to a closing force that is too high, for example, the ejector 6 may move in the closing direction beyond the closed position in direction P2. In this case, on the locking element 40, the projection 30 of the release part 8 may be inclined in a start area of a first guide section 41. When the release part 8 and the projection 30 move in the closing direction along the first guide section 41, the release part 8 comes into contact with the spring element 26, whereby a force is applied to the spring element 26 (see Figure 8). If the projection 30 of the release portion 8 reaches the end section of the first guide section 41, the projection 30, by means of the spring element 26 to which a force has been applied, can move along the third guide section 43. During the movement of the projection 30 along the third guide section 43, the lower side 32 of the release portion 8 comes into contact with the delay element 44. The lower side 32 of the release portion 8 can move along the chamfering of the delay element 44, due to which the delay element 44 is deformed or pressed in the direction of the guide slide 25.

By shifting the lower side 32 of the release portion 8 relative to the delay element 44, due to friction between the delay element 44 and the release portion 8, the movement of the release portion 8 along the third guide section 43 toward the release position of the release portion 8 can be delayed (see Figure 10).

If a user presses the drawer 53, the ejector 6 or the release element 8 starting from Figure 8, in the closing direction, the release part 8 in the third guide section 43 can move further in the closing direction, so that the release element 8 is in the safety position (see Figure 9). In the safety position, the release part 8 comes into contact with the stop 46 of the delay element 44. In addition, the release part 8 is pressed against the slide guide 28 of the release element 9 by means of the spring element 26. The ejector 6 presses the piston 45 of the damping element 11 in the closing direction, due to which a force is applied to the force unit 12. As soon as the user no longer exerts pressure on the drawer 53, by means of the force unit 12, the ejector 6 can move in the opening direction. In this way, the release part 8 can move along the slide guide 28 of the release element 9 until the release position of the release part 8 has been reached (see Figure 10).

If the release portion 8 is in the release position, the release element 9 can be moved from a rest position to a release position by moving the drawer 53 in the closing direction. In this way, the blocking of the force accumulator 4 can be removed, and the ejector 6 moves the drawer 53 in the opening direction. When the ejector 6 moves open, the projection 30 of the release portion 8 can be displaced lengthwise in the second guide section 42.
