Abstract
Description
[Technical Field]
[0001] This invention relates to a drive device in the form of a pop-out mechanism for furniture accessories, used to move a movable furniture component relative to the furniture body from a closed position to an open position. The drive device includes: a housing; a pop-out mechanism movable relative to the housing for transmitting a force to the movable furniture component in the opening direction; an energy storage device for applying a force to the pop-out mechanism; a stop for limiting the movement of the pop-out mechanism in the closing direction, wherein the housing preferably includes the stop; and an adjustment mechanism by which the gap between the pop-out mechanism and the adjustment mechanism in the closing direction can be adjusted in the closed position, wherein the adjustment mechanism is arranged on the housing. Furthermore, this invention also relates to a piece of furniture with such a drive device and a method for adjusting the depth of such a drive device. [Previous Technology]
[0002] To ensure the aesthetic appeal and logical movement of movable furniture components (such as drawers), it is crucial that the front panels of the furniture be precisely aligned with each other and with respect to the guide system, the main body of the furniture, or the drive mechanism. A key aspect of adjusting the gaps between movable furniture components and the drive mechanism or the main body of the furniture is ensuring precise depth adjustment (particularly within the range of 0.05 mm to 8 mm) in the opening and closing directions of the movable furniture components to achieve a wide range of applications and an attractive appearance.
[0003] Document EP 2 983 554 B1 provides an adjustment mechanism in the form of a depth adjustment wheel for adjusting the depth of the drawer front panel relative to the furniture body. This depth adjustment wheel allows modification or adjustment of the gap between the drawer front panel and the furniture body within a range of 2.5 mm to ensure a uniform appearance of the drawer front panel. This depth adjustment wheel is fixed to the housing of the ejector mechanism, where the position of the locking recess is adjustable. A particularly disadvantageous aspect in this case is that the installer needs considerable sensitivity to account for the drawer's suspended installation on the guide system and to achieve accurate depth adjustment of the ejector mechanism within a limited adjustment range of approximately 2.5 mm.
[0004] In document WO 2019 / 056035 A1, the depth adjustment wheel is intentionally omitted so that a maximum tolerance range of 5 mm can be kinematically compensated for in each closing motion by means of a coupling device arranged between the transmission device and the release mechanism. Therefore, the drive mechanism is readjusted by the coupling device in each locking process, requiring a complex closing mechanism and failing to ensure a uniform gap between the drawer front panel and the furniture body. In this process, the focus is on ensuring the proper functioning of the drive mechanism within a limited adjustment range. Similarly, a disadvantage is that adjusting the gap between the drawer and the furniture body or the depth of the pop-out device is laborious and depends on the installer's skill and manufacturing tolerances in the guide system. [Summary of the Invention]
[0005] The objective technical task of the present invention is to provide an improved pop-out device relative to the prior art, as well as a piece of furniture and a depth adjustment method, which at least partially eliminate the shortcomings of the prior art and enable adjustment of the front panels of multiple furniture components relative to the furniture body or multiple furniture bodies in a particularly convenient, precise and / or uniform manner.
[0006] This task is solved by the feature of request item 1.
[0007] Therefore, according to the present invention, the distance between the pop-out mechanism and the adjusting mechanism in the closed position can be adjusted by the adjusting mechanism through the stop or the housing and the movement of the pop-out mechanism relative to the adjusting mechanism, preferably a substantially translational movement—preferably from the closed position to the overpressure position in the closing direction.
[0008] Thus, the gap between the movable furniture parts and the furniture body can be precisely preset by the distance between the pop-out mechanism and the stop, and the installer only needs to push the furniture body during the furniture installation process to comfortably transfer the distance between the pop-out mechanism and the stop to the gap between the movable furniture parts and the furniture body with one hand.
[0009] Furthermore, the installation and depth adjustment of the drive unit or multiple movable furniture components are particularly convenient and quick. For example, the drive unit has already determined the predetermined standard dimensions between the movable furniture components and the furniture body, and these dimensions are automatically generated during the initial movement of the movable furniture components or pop-out mechanisms to the fully overpressed position after the closed position. After the movable furniture components are attached to the furniture body, the initial overpressed movement can be completed during the initialization process of the drive unit, where adjustment comfort is improved due to the automation of the adjustment process.
[0010] Generally, the overpressure location is related to movable furniture parts, and preferably, the overpressure location is related to the pop-out mechanism—especially relative to the housing. For example, the pop-out mechanism can be guided into an overpressure groove or overpressure channel in a guide rail.
[0011] Preferably, the pop-out mechanism is freely movable relative to the housing between a closed position and an open position and / or an overpressure position due to pressure and / or tension. Preferably, during adjustment by means of an adjusting mechanism, it is guided by a guide rail, wherein preferably, the guide rail (together with the housing) has a locking position for the closed position (for the drive mechanism or movable furniture component). In other words, during adjustment by means of the adjusting mechanism, the pop-out mechanism is preferably not fixed relative to the housing, except for contact between the pop-out mechanism and the stop or housing to limit relative movement.
[0012] Furthermore, the depth adjustment of the stop or housing relative to the adjustment mechanism requires only one operation for accurate and convenient transfer of the distance between the ejection mechanism and (preferably) the adjustment mechanism (which is fixedly mounted on the guide device), and this adjustment can be canceled and re-executed as needed (as a reset option). However, in principle, only one depth adjustment is necessary, and no structural modifications are required other than the adjustment mechanism itself—e.g., modification as an additional component.
[0013] Additionally, multiple drive units with the same distance between the stop and the pop-out mechanism can be provided, this distance being achieved in the same or uniform manner in the gap between the movable furniture parts and the furniture body. Therefore, installers do not need to monitor the relative positions of numerous furniture front panels, can flexibly adjust the gaps, and, if necessary, can set up an additional adjustment device (for fine adjustment of the movable furniture parts relative to the furniture body, if necessary), to accommodate, for example, the special dimensions of the guide system or any unforeseen gaps. However, it is generally unnecessary to adjust each existing drive unit to meet requirements, adapt to motion techniques, or surrounding movable furniture parts by rotating the depth adjustment wheel. Thus, pre-adjustment of the drive units can also prevent misadjustments during installation.
[0014] Preferably, the adjusting mechanism is located at least partially behind the housing of the ejector device in the closing direction.
[0015] Preferably, the gap between the movable furniture parts and the furniture body is set to approximately 2.5 mm in the closed position by means of the adjustment mechanism.
[0016] Another advantage is that this automatic depth adjustment solution for movable furniture component drive mechanisms is cost-effective because it does not require intervention in the kinematics of the drive mechanism and can be retrofitted as an add-on to existing drive mechanisms. Furthermore, it allows for flexible positioning of the adjustment mechanism and housing; the adjustment mechanism can be used for tolerance / clearance compensation and can be used and adjusted over a wide range of gaps between the movable furniture component and the furniture body. Installers do not require highly skilled personnel to adjust the drive mechanism.
[0017] The position of the housing or stop can be movable, thus allowing for a variety of structural designs for the adjustment mechanism, without requiring complex and / or numerous structural components. For example, the adjustment mechanism can function in different variations with increased volume by means of a wheel or by changing the position of an element. Generally, the spacing can be locked, deactivated, and adjusted into smaller discrete or continuous portions within a larger interval—while allowing for one-time automatic depth adjustment of movable furniture parts connected to the drive mechanism.
[0018] Generally, the point at which the distance between the pop-up mechanism and the adjusting mechanism is defined and determined is irrelevant, as long as the distance between the pop-up mechanism and the adjusting mechanism (or the guide device or the furniture body) in the closed position can be changed, or ultimately, the distance between the movable furniture part and the furniture body in the closed position can be changed. For example, it can be assumed that the distance is between the outer edge of the pop-up mechanism and the outer edge of the adjusting mechanism towards the movable furniture part in the closing direction. Generally, the housing is pushed on the guide device or relative to the furniture body, where it is also possible to move / push only the housing stop for adjustment.
[0019] Typically, the depth adjustment wheel is not mandatory. The further the pop-out mechanism is adjusted towards the stop, the greater the deviation of the movable furniture component's front panel from the closed position to the open position. This degree can be preset to any value.
[0020] Preferably, the pop-out device is a pop-out device that is partially tensioned by at least one spring between a closed or overpressured position and an open position. The pop-out device is separate from the drive member that is always connected to the movable furniture part, wherein an additional accumulator is usually provided as a substitute or supplement.
[0021] As mentioned at the beginning of the text, protection is also sought for a type of furniture, which includes a furniture body, at least one furniture component movable relative to the furniture body—preferably a drawer—and at least one drive device according to one of the preceding claims, the drive device being used to apply force to the at least one movable furniture component from a closed or overpressed position to an open position of the at least one movable furniture component.
[0022] Furniture accessories are preferably in the form of guide devices, which include a main guide rail and a slide rail movable relative to the main guide rail. However, generally, the furniture is not limited to a single drawer pull-out guide device. By means of a drive mechanism, multiple movable furniture parts (such as drawers) can be automatically adjusted in depth relative to each other by sliding motion.
[0023] As stated at the beginning of the text, a method is also sought to protect the depth adjustment of movable furniture parts that interact with the drive device relative to the furniture body, preferably for such drive devices, characterized by the following steps: - The pop-out mechanism preferably contacts the stop of the housing by the movable furniture part either moving from a closed position or being pushed to an overpressed position, preferably the movable furniture part contacting the furniture body; and - The distance between the pop-out mechanism and the adjustment mechanism in the closed position is automatically adjusted by means of the adjustment mechanism by a relative movement between the housing or the stop and the adjustment mechanism.
[0024] The steps of these two methods may temporarily overlap, wherein the depth adjustment of the drive device or movable furniture component is preferably completed between the contact stop and the contact furniture body.
[0025] The present invention does not limit the number of structural components. Features of the device can be applied to features of the method, and vice versa. Advantageous embodiments of the invention are defined in the appended claim.
[0026] According to an advantageous embodiment of the present invention, when the pop-out mechanism is kinematically coupled to the stop or when the pop-out device is in contact with the stop, the distance between the pop-out mechanism and the adjustment mechanism can be adjusted by means of the pop-out mechanism.
[0027] The pop-out mechanism can therefore function as a transmission member that pushes the stop or housing relative to the adjustment mechanism to ensure the correct positioning of the pop-out mechanism—achieved by the closing movement of the movable furniture parts.
[0028] Advantageously, the distance between the pop-up mechanism and the adjustment mechanism can be automatically adjusted during the movement of the pop-up mechanism toward the closing direction, preferably during the overpressure movement from the closed position toward the closing direction.
[0029] This ensures that when installing movable furniture parts, the installer only needs to move the movable furniture parts to the stop position in the overpressure position of the drive device, and the drive device can automatically generate a uniform gap between the movable furniture parts and the furniture body in one go.
[0030] It has proven advantageous that the distance between the pop-up mechanism and the adjusting mechanism can be adjusted to a preset value, wherein the preset value is preferably set as follows: the preset value depends on the preset distance between the pop-up mechanism and the stop in the closed position.
[0031] For example, the desired spacing can be stored in the adjustment mechanism. Preferably, the distance between the pop-out mechanism and the stop (which is required or necessary for the pop-out motion mechanism) is transferred by the adjustment mechanism in such a way that the adjustment mechanism transmits the preset value as the gap between the movable furniture component and the furniture body—for example, when the movable furniture component is pressed against the furniture body in an overpressure position.
[0032] For example, if the pop-out device is mounted on the guide device and the movable furniture component is connected to the pop-out device, in the closed position, there may be a gap of 5 mm between the movable furniture component and the furniture body, for example, wherein the ideal distance between the movable furniture component and the furniture body is 2.5 mm and may correspond to a preset distance between the pop-out mechanism and the stop. If the movable furniture component moves to the over-pressed position and presses against the furniture body, the stop (if necessary, if adjacent to the pop-out mechanism) or the housing moves 2.5 mm toward the separated (preferably positioned and / or fixed behind the housing in the closing direction) adjustment mechanism, wherein then in the closed position, there will be a desired gap of 2.5 mm between the movable furniture component and the furniture body.
[0033] According to an advantageous embodiment of the invention, the distance between the pop-out mechanism and the adjustment mechanism can be changed by up to 8 mm, preferably within the range of 1.5 mm and 3.5 mm and / or with an accuracy between 0.05 mm and 0.15 mm.
[0034] Accuracy can be determined, for example, by an additional locking device (a supplementary locking mechanism) as a check lock with discrete locking positions. Continuous adjustability can also be considered—for example, by moving along an inclined plane.
[0035] According to an embodiment of the present invention, it has been proven that it is advantageous for the drive device to include an adjustment device separate from the adjustment mechanism to adjust the distance between the pop-out mechanism and the stop, wherein the adjustment device is arranged on the housing, preferably on the stop, and / or on the pop-out mechanism.
[0036] For example, the adjustment device can be designed in the form of a depth adjustment wheel known in the prior art. Preferably, the adjustment device is arranged on the pop-out mechanism or stop and actuates the pop-out mechanism relative to the stop or housing. This means that special dimensions can be used for the furniture or fine-tuning, wherein the fine-tuning is independent of the automatic adjustment performed by the adjustment mechanism, but can interact indirectly with the stop during the activation of the adjustment mechanism, so that the fine-tuning still exists after the adjustment mechanism is activated and / or can be changed thereafter.
[0037] An advantageous variation is that the adjusting device is spatially spaced from the adjusting mechanism and / or includes a worm, an adjusting wheel, a threaded pin, or an eccentric wheel.
[0038] In this way, installers can adjust the distance with particular ease by rotating—for example, without tools or with the aid of a screwdriver.
[0039] Preferably, the drive device includes a locking device that can suppress the movement of the ejector mechanism in the opening direction, wherein the locking device can be unlocked by overpressure movement in the closing direction.
[0040] In the touch latch function mode after the overpressure area is in the closed position, movable furniture parts can be moved to the open position without gripping, which, combined with the damping device, ensures a particularly coordinated movement trajectory.
[0041] Preferably, the adjusting mechanism includes an additional locking device, preferably a locking device or a check lock, by means of which the distance between the ejector mechanism and the adjusting mechanism in the closed position can be locked, the distance being determined by the displacement of the stop or the housing relative to the adjusting mechanism.
[0042] This additional locking device prevents the need for readjustment of the spacing or changes in the spacing, for example, due to accidental vibration. Furthermore, this additional locking device can also provide a (manually operable) reset mechanism as a reset function.
[0043] According to one embodiment of the present invention, the adjustment mechanism includes a separate housing that is separate from the housing. The separate housing may be attached to the housing as an attachment or arranged together with the housing on a support.
[0044] The separate housing makes it quite convenient to retrofit existing drive units, for example, by connecting the reset spring of another housing to the housing as a connector.
[0045] According to a preferred embodiment of the invention, the adjustment mechanism includes a reset mechanism by which the distance between the pop-up mechanism and the adjustment mechanism, as determined by the adjustment mechanism, can be canceled by releasing the other locking device. Preferably, the reset mechanism includes a spring, a rocker arm, a slider, a latch, or a wheel.
[0046] By means of the reset mechanism, the spacing determined by the adjustment mechanism can be canceled and redefined - for example, to adjust the degree of offset of the spacing between the pop-up mechanism and the stop or between the movable furniture parts and the furniture body.
[0047] It has been found that it is advantageous for the adjustment mechanism to include a reset spring that is functionally connected to the adjustment mechanism and the housing, as the reset spring can increase the distance between the pop-up mechanism and the adjustment mechanism.
[0048] This eliminates the distance that separates the pop-up mechanism from the adjustment mechanism in the closed position, so that the desired spacing can then be determined by readjustment. In this respect, the reset spring must be designed to be wide enough to include other accumulators (such as fluid accumulators).
[0049] In addition, it is preferable to configure the following: the pitch can be adjusted by the adjustment mechanism via a transmission mechanism, an adjustment wheel, an inclined plane or a worm gear.
[0050] The transmission mechanism can particularly advantageously influence the end position of the ejector mechanism. The transmission mechanism can be used as an alternative or supplement to achieve the transmission ratio, i.e., the small displacement of the stop in the adjustment mechanism is transmitted by the transmission ratio, so as to achieve, for example, a shorter adjustment interval.
[0051] In a preferred embodiment of the invention, the distance between the pop-up mechanism and the adjustment mechanism is set to a value predefined by the pop-up mechanism, or set only once.
[0052] The predetermined value, which is set only once before the spacing is reset, can be adjusted by the contact between the movable furniture parts and the furniture body and / or generated by the distance between the stop and the pop-out mechanism in the closed position.
[0053] According to an advantageous design of the invention, the resetting mechanism is operated such that the resetting spring eliminates the predetermined gap between the pop-up mechanism and the adjusting mechanism.
[0054] Preferably, for multiple movements of the pop-out mechanism toward the closed position, the adjustment of the interval between the pop-out mechanism and the adjustment mechanism is performed only once.
[0055] In this case, the resulting gap can be mechanically stored in the adjusting mechanism, for example, by means of an additional locking device. If discrete adjusting intervals are provided by the adjusting mechanism, the gap can be prevented from changing during operation.
[0056] Preferably, in the method steps of the preceding or following stage, preferably in the closed position, the distance between the ejector mechanism and the stop is adjusted by the adjusting device.
Implementation Method
[0066] Figure 1 shows a piece of furniture comprising a main body 3, a drawer-shaped furniture component 2 movable relative to the main body 3, and a drive mechanism. Above the drawer shown is another drawer, which is actuated by the visible drive mechanism—but is hidden for visual clarity. The number of drive mechanisms for each movable furniture component 2 is typically arbitrary. Each movable furniture component 2 may have only one drive mechanism, or two drive mechanisms may be provided on the two side walls of the main body 3—for example, connected by a synchronization device. The drive mechanism is configured to apply force to push the movable furniture component 2 from a closed or over-pressurized position to an open position.
[0067] Figure 2a shows a drive device connected to the guide device 33, which is in the form of a pop-out device 1 for furniture accessories in the form of the guide device 33. The drive device is used to move movable furniture parts 2 relative to the furniture body 3. The drive device includes a housing 6 connected to the adjustment mechanism 10 and the guide device 33.
[0068] Figure 2b shows a top view of the drive device coupled to the guide device 33, wherein the pop-out device 1 includes a pop-out mechanism 7 movable relative to the housing 6 for transmitting force from the pop-out device 1 to the movable furniture component 2 in the opening direction, and a stop 9 for limiting the movement of the pop-out mechanism 7 in the closing direction. The housing 6 includes the stop 9, which is not mandatory.
[0069] By means of the adjustment mechanism 10, the pop-out mechanism 7 can be adjusted in the closed position 4 at a distance 11 relative to the adjustment mechanism 10 in the closing direction (see, for example, Figure 7a), wherein the adjustment mechanism 10—usually indirectly or directly—is arranged on the housing 6.
[0070] Figure 2c shows the ejector device 1, which is separate from the guide device 33. The distance 11 of the ejector device 7 relative to the adjustment mechanism 10 in the closed position 4 can be adjusted by the adjustment mechanism 10 through the stop 9 and the housing 6, which are substantially translated relative to the adjustment mechanism 10 from the closed position 4 to the overpressure position 12 in the closing direction. The closed position can be defined by the closed posture of the movable furniture component 2, which has a gap with the furniture body 3, and the ejector device 1 is locked or can be unlocked by overpressure movement.
[0071] Figure 3a shows a preferred embodiment of the pop-out mechanism 10, wherein the distance 11 between the pop-out mechanism 7 and the adjustment mechanism 10 can be adjusted by means of the pop-out mechanism 7 when the pop-out mechanism 7 is kinematically coupled to the stop 9 and after the pop-out mechanism 7 contacts the stop 9.
[0072] The distance 11 between the pop-out mechanism 7 and the adjustment mechanism 10 can be adjusted to a preset value, wherein the preset value depends on the preset distance 13 between the pop-out mechanism 7 and the stop 9 in the closed position 4 or is obtained by subtracting the distance 13 in the closed position 4 from the distance between the pop-out mechanism 7 and the adjustment mechanism 10 in the overpressure position 12.
[0073] As shown in the enlarged detail view in Figure 3b, the adjustment mechanism 10 includes a plurality of reset springs 29 that are functionally connected to the adjustment mechanism 10 and the housing 6. These reset springs can (when the adjustment mechanism 10 is released from locking) increase the distance 11 between the pop-out mechanism 7 and the adjustment mechanism 10. Generally, one reset spring 29 is sufficient for the reset function of the housing 6 or the stop 9 relative to the adjustment mechanism 10.
[0074] The pitch 11 is adjusted by means of the worm gear 32.
[0075] Figures 3c and 3d show a drive device 1 with an adjustment mechanism 10, wherein the pitch 11 can be adjusted by the adjustment mechanism 10 via a transmission mechanism 34. The transmission mechanism 34 rotates a first worm 32 by a relative displacement of the ejector mechanism 7 and the housing 6 relative to each other. The first worm causes a second worm 32 to rotate, wherein the second worm presses a transmission member (e.g., in the form of a rod) against a stop 9, causing the stop 9 to move relative to the ejector mechanism 7. According to this embodiment, teeth for transmitting motion between the ejector mechanism 7 and the stop engage in a sector element.
[0076] Typically, a spring can be arranged in the area of the transmission mechanism 34 as a reset spring 29 for the reset function.
[0077] According to this embodiment, the two worm gears 32 are coupled by a body having two pointed conical ends.
[0078] The adjustment mechanism 10 has another housing 21 that is separate from the housing 6. This other housing can be attached to the housing 6 as an attachment or arranged together with the housing 6 on a bracket 22.
[0079] According to this embodiment, housing 6 may remain stationary relative to another housing 21, wherein it is generally preferred that housing 6 is movable relative to another housing 21.
[0080] Figures 4a to 4c show an embodiment of an adjustment mechanism having an adjustment wheel 30.
[0081] The drive device includes an adjustment device 14 separate from the adjustment mechanism 10, which is used to adjust the distance 13 between the ejector mechanism 7 and the stop 9, wherein the adjustment device 14 is arranged on the ejector mechanism 7. Generally, the adjustment device 14 may also be arranged on the stop 9 or the housing 6.
[0082] As can be seen in Figure 4b, the adjusting mechanism 10 and the housing 6 are coupled by a rack, wherein the distance 11 between the pop-out mechanism 7 and the adjusting mechanism 10 is automatically adjusted during the process of the pop-out mechanism 7 moving toward the closing direction and during the process of the pop-out mechanism 7 moving toward the closing direction from the closed position 4.
[0083] The distance 11 between the pop-out mechanism 7 and the adjustment mechanism 10 can be changed by up to 8 mm, with an accuracy between 0.05 mm and 0.15 mm.
[0084] Figures 5a to 5n illustrate various preferred embodiments of the adjusting mechanism 10. Individual structural components may be alternative or complementary, thus it is not necessary to provide all structural components. In Figure 5a, the adjusting mechanism 10 includes a worm gear 32 and a reset mechanism 23 in the form of a rocker arm 25, wherein the adjusting mechanism 10 includes another locking device 20 in the form of a tooth, serving as a check lock or locking device, which complements the locking device 19 for the ejector mechanism 7. The adjusting mechanism 10 includes a transmission mechanism 34 and a reset spring 29. For example, the transmission mechanism 34 and the reset mechanism 23 may be omitted.
[0085] The difference between Figure 5b and Figure 5a is that the reset mechanism 23 exists in the form of a latch 27. In Figure 5c, the adjusting mechanism 10 includes an inclined plane 31, wherein the reset mechanism 23 exists in the form of a latch 27. In Figure 5d, the adjusting mechanism includes a worm gear 32, wherein the gap 11 can be eliminated by means of the reset mechanism 23, which is connected to the reset spring 29 and is in the form of a rocker arm 25. In Figure 5e, the reset mechanism 23 includes a wheel 28, wherein, as an alternative or supplement, a spring can be provided on the transmission mechanism 34 to achieve the reset function of the gap 11.
[0086] Figure 5f shows the combination of the inclined plane 31 and the reset mechanism 23 in the form of a slider 26. Figure 5g shows the embodiment according to Figure 5e, which has an exposed second worm 32, wherein Figure 5h shows a transmission member that moves between the two worms 32 relative to Figure 5e, Figure 5i shows the two worms 32 exposed, and in Figure 5j, relative to Figure 5e, when the position of the adjusting mechanism 10 changes, the first worm 32 is exposed below the wheel 28. Figures 5k and 5l show the adjusting mechanism 10 with two worms 32 when the reset mechanism 23 in the form of a rocker arm 25 is in different positions. Figures 5m and 5n show an adjusting mechanism 10 having an inclined plane 31 (with teeth as an additional locking device 20) and a reset mechanism 23 in the form of a latch in different positions—for example, due to the reset spring 29, or due to the displacement of the stop 9 relative to the adjusting mechanism 10.
[0087] In Figure 6a, the housing sidewall of the housing 6 is hidden, and it can be seen that the ejection device 1 includes an energy storage device 8 for applying force to the ejection mechanism 7 and a locking device 19, by means of which the movement of the ejection mechanism 7 in the opening direction can be suppressed, wherein the locking device 19 can be unlocked by overpressure movement in the closing direction.
[0088] According to this embodiment, the adjusting mechanism 10 includes an additional locking device 20 in the form of a locking device as a check lock, by which the locking device can lock the distance between the pop-out mechanism 7 and the adjusting mechanism 10 in the closed position 4, the distance being determined by the displacement of the stop member 9 or the housing 6 relative to the adjusting mechanism 10.
[0089] The adjustment mechanism 10 has a reset mechanism 23, by which the gap 11 between the pop-out mechanism 7 and the adjustment mechanism 10 can be eliminated by releasing another locking device 20. This gap is determined by the adjustment mechanism 10. In this embodiment, the reset mechanism 23 is in the form of a rocker arm 25.
[0090] The adjusting device 14 is spatially spaced from the adjusting mechanism 10.
[0091] Figures 6b to 6d show an adjustment device 14, which includes an eccentric wheel 18 for changing the distance 13.
[0092] In Figure 6e, the adjusting device 14 includes a worm gear 15, which can be operated with a screwdriver.
[0093] Figure 6f shows an adjustment device 14 that can be operated without tools, the adjustment device including an adjustment wheel 16.
[0094] Generally, the adjusting device 14 can be mounted on the housing 6, wherein the distance 13 can be changed, for example, by means of a threaded pin.
[0095] Figures 7a to 7h illustrate the adjustment and reset process of the adjustment mechanism 10 based on the structural design of the adjustment mechanism 10 in Figure 6a. An exemplary method for adjusting the depth of a drive device or a movable furniture component 2 that interacts with the drive device relative to the furniture body 3 can be described as follows: Starting from the closed position 4 according to Figure 7a, the pop-out mechanism 7 is pushed by the movable furniture component 2 to the overpressure position 12 according to Figure 7b, so that the pop-out mechanism 7 contacts the stop 9 of the housing 6 and the movable furniture component 2 contacts the furniture body 3. By means of a relative movement between the housing 6 or the stop 9 and the adjustment mechanism 10, the distance 11 between the pop-out mechanism 7 and the adjustment mechanism 10 in the closed position 4 is automatically adjusted by the adjustment mechanism 10. In the illustrated embodiment, during the adjustment of the distance 11, the locking according to Figure 7c is temporarily eliminated and the distance 11 between the pop-out mechanism 7 and the adjustment mechanism 10 is automatically adjusted to a value preset by the pop-out device 1. Furthermore, this value is generated by the movable furniture component 2 contacting the furniture body 3.
[0096] In Figure 7d, the additional locking device 20 is activated, wherein in Figure 7e, the kinematic structure associated with the electrocardiogram waveform profile cooperates with the pop-out mechanism 7 to achieve the resetting of the pop-out mechanism 7 relative to the stop 9 and the locking of the gap 11 at the closed position 4 by the additional locking device 20.
[0097] In Figure 7f, the reset mechanism 23 is operated, thereby resetting the spring 29 to eliminate the predetermined gap 11 between the pop-up mechanism 7 and the adjusting mechanism 10 and return to the initial position according to Figure 7g. In Figure 7h, after the operation of the reset mechanism 23 is completed, the pop-up device 1 is readjusted to the initial position according to Figure 7a. The reset mechanism 23 may be a spring-loaded design.
[0098] Therefore, for multiple movements of the pop-out mechanism 7 toward the closed position 4, the distance 11 of the pop-out mechanism 7 relative to the adjustment mechanism 10 can be adjusted once—until the reset mechanism 23 is operated when necessary.
[0099] In the method steps before or after adjusting the spacing 11, the distance 13 between the pop-out mechanism 7 and the stop member 9 can be adjusted by adjusting the adjusting device 14, for example, in the closed position 4. [Simplified Explanation of the Diagram]
