Description

Technical Field

[0001] The present invention relates to a projection device for a movable furniture part for moving the movable furniture part in the direction from the closed position to the open position, including a housing, a projection device movable relative to the housing for transmitting force in the opening direction from the projection device to the movable furniture part, a force storage device for biasing the projection device, and a locking device for preventing the movement of the projection device in the direction of the open position at the locking position of the locking device. Furthermore, the present invention relates to a furniture having at least one such projection device. Furthermore, the present invention relates to a method of operating such a projection device.

[0002] Projection devices for movable furniture parts are already known from WO 2011 / 015663, in which case the locking device is guided on a guide track. When the locking device is guided by the projection device onto the inclined surface of the locking device, the unlocking of the projection device takes place. The over-pressing of the projection device is avoided by means of a damper or an elastic stopper for the movable furniture part.

[0003] A disadvantage of the prior art is that, at the high speed of the movable furniture part in the closing direction, the damper designed for automatic retraction as well as the elastic stopper provided for fixing the closed position of the movable furniture part harbour the risk of an undesired projection of the movable furniture part.

[0004] Therefore, the objective technical problem of the present invention is to provide an improved projection device compared to the prior art, in which the disadvantages of the prior art are at least partially eliminated, in particular characterized by a reliable locking position of the locking device and / or a comfortable unlocking of the locking device.

[0005] This problem is solved by the features of claim 1.

[0006] Accordingly, in the present invention, the ejection device is intended to include at least one release device separate from the locking device and the ejection device for contact and / or interaction with the locking device, and the at least one release device is positioned on the ejection device.

[0007] This makes it possible for the first time to generate a pass-through pressure prevention mechanism via at least one release device that can guarantee locking or unlocking of the protruding device depending on the motion trajectory and / or motion speed of the protruding device. Unwanted protrusion when locking is desired can be effectively prevented despite the high acceleration of the movable furniture part.

[0008] As mentioned at the beginning, protection of rights can also be sought for furniture that includes the furniture body, at least one furniture part that is movable relative to the furniture body, and at least one such protruding device.

[0009] As mentioned at the beginning, a patent application has also been filed for the method of operating such a protruding device, and the following method steps are performed: - The ejecting device is moved from the open position to the closed position together with the control device and at least one release device. - The ejection device is moved from the closed position to the overpressed position together with at least one release device, - The ejecting device moves back from the overpressed position to the closed position together with at least one release device, and at least one release device pivots particularly buffered in a direction perpendicular to the opening direction, so that at least one release device contacts the locking device in the closed position, and the locking device in the locked position prevents the ejecting device from moving in the opening position together with the control device and at least one release device.

[0010] Preferred embodiments of the present invention are defined in the dependent claims.

[0013] Figure 1 shows a piece of furniture 18 that includes a furniture body 19, three furniture components 2 in the form of drawers that are movable relative to the furniture body 19, and two projection devices 1 for extending the drawers (hidden by the drawers). The two projection devices 1 (not shown for clarity in the figure) are positioned on the furniture body 19 in substantially mirror-symmetrical form (see Figure 2a).

[0014] The first locking device 9 and the second locking device 9 can be unlocked (synchronously or asynchronously) in a plane 29 that is substantially parallel to the furniture body 19, and may be configured of the same type.

[0015] The methods and arrangements for furniture 18 described below are applicable under all embodiments of the projection device 1.

[0016] The movable furniture component 2 is preferably in the form of a drawer, and the projection device 1 is particularly preferably positioned below the drawer. Generally, it is also possible to apply other movable furniture components 2—such as hinged doors—or to the side of the movable furniture component 2.

[0017] The projection device 1 is preferably fixed to a guide device for movable furniture parts 2, which includes a main rail for attachment to the furniture body 19, a loading rail, and optionally an intermediate rail.

[0018] Figure 2a shows a protruding device 1 having an assembled housing 5 and a schematically illustrated synchronous shaft 17, the synchronous shaft 17 is generally provided (to cause synchronous unlocking of the locking device 9 which generally exists without the synchronous shaft 17, and not asynchronous unlocking), or can be retrofitted via an optional interface, but is not necessarily required for the function of the movable furniture part 2.

[0019] For example, pressing the movable furniture component 2 in the central area of ​​the front of the furniture can initiate the operation of both protruding devices 1 by the pressing action. If only one of the locking devices 9 is unlocked by the pressing operation—particularly by a lateral pressing operation on the movable furniture component 2—the functionality of bidirectional unlocking via a separate release device 13 prevents the movable furniture component 2 from getting stuck.

[0020] The synchronization shaft 17 is not necessary for the mechanism, which includes the movable furniture part 2 and the two protruding devices 1, in order to make the movable furniture part 2 protrude from the furniture body 19 in a practical manner (despite the eccentric pressing action on the movable furniture part 2).

[0021] Figure 2b shows a cross-sectional view of the projection device 1, which for a movable furniture part 2 includes a projection device 6 that is movable relative to the housing 5 to transmit force from the projection device 1 to the movable furniture part 2 in the opening direction 7 in order to move the movable furniture part 2 from a closed position 3 to an open position 4, a force storage device 8 for force-energizing the projection device 6, and a locking device 9 for preventing the projection device 6 from moving in the direction of the open position 4 when the locking device 9 is in the locked position 10.

[0022] Each ejection device 1 includes a control device 12 for transmitting force from the force storage device 8 to the ejection device 6, and when the locking device 9 is in the locked position 10, it is possible to prevent the movement of the control device 6 in the direction of the open position 4.

[0023] Both of the illustrated protruding devices 1 are held in a locked position through interaction with the control device 12 via a locking device 9, thereby locking the movement of the protruding device 6 toward the open position 4 of the movable furniture part 2.

[0024] The locking device 9 can be unlocked not only by a pressing action on the protruding device 6 in the closing direction 11 (corresponding to the closing direction 11 of the movable furniture part 2 to the position of use) via the protruding device 6, but also by a pulling action on the protruding device 6 in the opening direction 7 (corresponding to the opening direction 7 of the movable furniture part 2 to the position of use), thereby allowing the protruding device 6 to be operated in the opening direction 7 in order to extend the movable furniture part 2 from the furniture body 19.

[0025] Figure 2c shows the ejection device 1 in a cross-sectional view shifted from Figure 2b, revealing that the ejection device 6 includes a release device 13 in the form of a pivotable lever 14 that applies force to the ejection device 6 for contact with and interaction with the locking device 9.

[0026] The release device 13 is a separate component from the locking device 9 and the ejection device 6, for unlocking and / or locking the ejection device 6 via the locking device 9.

[0027] The particularly wide operating range of the ejection device 1 is linked to the release device 13, and the assurance of activation in the locking mechanism is embodied by relative positioning (particularly the placement of the release device 13 on the ejection device 6) and the movability of the components (particularly the guide track 15 for forming the pass-through pressure prevention section). This ensures the high functionality and flexible usability of the ejection device 1.

[0028] The protruding device 1, in relation to the protruding movement of the movable furniture part 2, generates only incidental noise despite the possibility of bidirectional unlocking and the potential asymmetry in the unlocking of the second locking device 9 during the release movement of the movable furniture part 2—which is generally mediated by the release dynamics of the movable furniture part 2. This ensures high operational comfort for the user of the movable furniture part 2.

[0029] The protruding device 6 is movable in the closing direction 11 relative to the locking device 9, and the locking device 9 can only be unlocked in the opening direction 7 by the movement of the protruding device 6.

[0030] Figure 2d shows the pivot position of the lever 14 relative to the locking device 9 in the right-side projection device 1 (unlike the left-side projection device 1), where the locking device 9 can be released by tension based on the force storage device 8 (hidden by the lower region of the housing 5).

[0031] The release device 13 is intended for contact with and interaction with the locking device 9, and the release device 13 is located on the protruding device 6.

[0032] In Figure 2e, it is clear that the locking device 9 is pivotable to release the control device 12 and the protruding device 6 via the lever 14 for unlocking.

[0033] The right-side projection device 1 has already been unlocked for projection, while the left-side projection device 1 has not yet been activated.

[0034] In Figure 2f, the ejection motion is already underway, and the ejection motion of the ejection device 1 on the right side has also released the ejection device 1 on the left side through force transmission from the lever 14 to the locking device 9.

[0035] The right-side ejection device 1 is unlocked by a pressing operation, and the left-side ejection device 1 is unlocked by a pulling operation, in order to release their respective ejection devices 6.

[0036] Figure 2g shows the projection device 1, with the components contained within the housing 5—particularly the force storage device 8 connected to the adjustment device—visualized on the right.

[0037] Figures 3a to 3f show enlarged views of the region involved in unlocking the ejection device 1, illustrating the progression of activation of the ejection device 6 during the overpressure motion (a pure tensile motion for releasing the ejection device 6 is also possible).

[0038] The release device 13 is rotatably positioned on the ejection device 1 and includes a contact contour 35 as a contact surface, and can contact the locking device 9 at two separate contact positions 37 and 38.

[0039] The contact contour 35 is curved to transmit a changing force to the locking device 9 when the pivot position of the lever 14 changes, and has notches 39 to prevent undesirable slippage of the protruding device 6 under the desired lock.

[0040] The ejection device 6, force storage device 8, control device 12, locking device 9, and release device 13 are guided by the guide track 15 of the housing 5.

[0041] The protruding device 6 is located partially outside and partially inside the housing 5, while the force storage device 8, control device 12, locking device 9, and release device 13 are located inside the housing 5.

[0042] Although this ejection device 1 is configured without a synchronization shaft, it may generally be provided with an interface 16 for connecting a synchronization shaft 17 to synchronize ejection device 1 with another ejection device 1.

[0043] One exemplary method for projecting a movable furniture component 2 from a closed position 3 to an open position 4 relative to the furniture body 19 using two projection devices 1 can be described as follows: - The first ejecting device 6 of the first ejecting device 1 of the two ejecting devices 1 is moved from the closed position 3 to the over-pressed position 22 by the pressure applied to the movable furniture part 2 in the closing direction 11, -The first force storage device 8 of the first ejection device 1 moves the first ejection device 6 toward the open position 4, thereby unlocking the first locking device 9 of the first ejection device 1, and moving the first ejection device 6 toward the open direction 7. - The movable furniture part 2 is moved together with the first protruding device 6 in the opening direction 7, thereby moving together with the second protruding device 6 of the second protruding device 1 of the two protruding devices 1 in the opening direction 7. - The second locking device 9 of the second protruding device 1 is unlocked without a synchronization axis by tension on the second protruding device 6 in the opening direction 7, thereby the second force storage device 8 of the second protruding device 1 transmits force to the second protruding device 6, and the movable furniture part 2 is forcefully biased toward the open position 4.

[0044] In this way, the first locking device 9 and the second locking device 9 can be unlocked from their respective locked positions 10 asynchronously (or synchronously) by the pressing motion of one of the ejecting devices 6 followed by the pulling motion of the second ejecting device 6.

[0045] Figures 4a, 6a, and 8a show preferred embodiments of the ejection device 1 in perspective views.

[0046] Figures 4b, 6b, and 8b show that the ejection device 1 comprises a housing 5, an ejection device 6, a force storage device 8, a control device 12, and a locking device 9.

[0047] The ejection device 1 includes a release device 13, and the ejection device 6 includes a release device 13 for contact and interaction with the locking device 9, and the release device 13 is located on the ejection device 6.

[0048] Figure 5a is an enlarged detailed view of the ejection device, clearly showing that the release device 13 is positioned directly on the ejection device 6, partially inside the ejection device 6, and directly between the ejection device 6 and the housing side wall 30 of the housing 5.

[0049] The release device 13 includes a shock absorber 31 in the form of a rotary damper (the specific configuration of the shock absorber 31 is not important), which is capable of dampening the rotation of the release device 13 around the rotation axis 32 located on the protruding device 6.

[0050] The buffer device 31 may form a timing element for contact between the release device 13 and the locking device 9, and may be intended as a pass-through pressure prevention part for the ejecting device 6 of the ejecting device 1 in relation to the overpressure position 22.

[0051] The shock absorber 31 is located directly within the protruding device 6.

[0052] Figures 5b to 5f show various positions of the release device 13, which exists in the form of a pivotable lever 14 that applies force to the protruding device 6.

[0053] The release device 13 is pivotably positioned on the protruding device 1 and has a contact contour 35 in the form of a curved contact surface with notches 39, which can contact the locking device 9 at two separate contact positions 37, 38. The locking device 9 can be unlocked via the protruding device 6 by pressing on the protruding device 6 in the closing direction 11 or by pulling on the protruding device 6 in the opening direction 7, thereby initiating the operation of the protruding device 6 in the opening direction and ensuring the protrusion of the movable furniture part 2 from the furniture body 19.

[0054] Starting from Figure 5a, in Figure 5b the ejection device 6 moves in the closing direction 11, causing the lever 14 to contact the locking device 9 in the locked position 10. In Figures 5c and 5d, the ejection device 6 moves to the overpressed position 22, and the lever 14 automatically pivots downward around the rotation axis 32 due to the force of the spring (while being cushioned by the shock absorber 31).

[0055] In Figure 5e, during the process of reaching the overpressure position 22, the lever 14 moves along the guide track 15, and as a result, when the ejection device 6 moves in the opening direction 7, the lever 14 contacts the locking device 9 via the contact contour 35, creating a new lock position 10. In contrast, in Figure 5f, during the process of reaching the overpressure position 22, the lever 14 is buffered by the guide track 15 (this is not always necessary in general) and can freely pivot downwards, so that when the ejection device 6 moves in the opening direction 7, the lever 14 contacts the locking device 9 via the contact contour 35, and the locking device 9 is released by sufficient force transmission to the locking device 9.

[0056] In Figures 5e and 5f, the pass-through pressure prevention section is materialized in the ejection device 1. When the movable furniture part 2 moves at a high speed in the closing direction 11, the lever 14 is operated via the guide pin to the area shown in the upper part of the guide track 15 - the pass-through pressure track at the overpressure position 22 - so that when the ejection device 6 subsequently moves in the opening direction 7, the lever 14 - by force via a spring connected to the ejection device 6 and via the shock absorber 31 - contacts the locking device 9 at the first contact position 37, adjusting the lock position 10 and preventing unwanted ejection. If it is desired that the movable furniture part 2 be extended from the locked position 10, the lever 14 moves from the locked position 10 to the area of ​​the guide track 15 shown on the lower side of the drawing—the unlock track at the overpressed position 22—and at this time the lever 14 has sufficient time to contact the locking device 9 at the second contact position 38 when the extension device 6 returns to the release direction 7. At the second contact position 38, a sufficient force ratio is established for the unlocking of the locking device 9 and the subsequent release of the extension device 6.

[0057] An example method for operating the ejection device 1 can be described as follows: -The protruding device 6 moves from the open position 4 to the closed position 3 together with the control device 12 and the release device 13. -The ejection device 6 moves together with the release device 13 from the closed position 3 to the overpressed position 22. - The ejection device 6 moves back from the overpressed position 22 towards the closed position 3 together with the release device 13, and the release device 13 pivots while being buffered in a direction perpendicular to the opening direction 7, thereby the release device 13 comes into contact with the locking device 9 at the closed position 3, and the locking device 9 at the locked position 10 prevents the ejection device 6 from moving towards the open position 4 together with the control device 12 and the release device 13.

[0058] The lock position 10 can be released by a tensile force on the ejecting device 6 or by an over-pressure movement of the ejecting device 6.

[0059] Figures 7a to 7e, 9a to 9d, and 10a to 10e illustrate the kinematic interactions of components involved in locking and unlocking the ejector device 1 in alternative design configurations and in lock / unlock mechanisms similar to those described above for the function of the ejector device 1. For example, the locking device 9 may be configured as a swivelable unlocking lever or as an inclined surface of the guide track 15. The return of the force storage device 8 may be intended via, for example, a linear start carriage, a rotatably supported return device biased by a leaf spring, or a combination thereof.

[0060] Figure 11 shows a piece of furniture 18 having three movable furniture parts 2 that are slidable relative to the furniture body 19, with one movable furniture part 2 removed to expose the projection device 1.

[0061] Opposite the protruding device shown in the diagram, a second protruding device 1, which is mirror-image symmetrical, is positioned on the furniture body 2.

[0062] This embodiment of the ejection device 1 also includes a housing 5, an ejection device 6, a force storage device 8, a control device 12, a locking device 9, and a release device 13.

[0063] The projection device 1 can be modularly connected to a guide system for movable furniture parts, and / or retrofitted to the guide system as an add-on.

[0064] Figure 12a shows that the ejection device 1 includes a release device 13 for direct contact with the locking device 9, and indirect contact is generally considered to be the same.

[0065] The release device 13 is rotatably positioned on the ejection device 1 and includes a contact contour 35, which can contact the locking device 9 at two separate contact positions 37, 38 for maintaining the locked position 10 or for unlocking the locking device 9.

[0066] The contact contour 35 is curved and has tooth tips in the form of notches 39, and the release device 13 is in the form of a force-driven swivelable lever 14 and is directly attached to the ejection device 6.

[0067] As with other embodiments of the ejection device 1, a buffer device 31 for the release device 13 is generally provided, which acts as a timing element for the lever 14, and the ejection device 1 can be unlocked by tension and pressure without necessarily requiring the synchronization shaft 17.

[0068] In this embodiment, a mechanism is intended that includes two ejection devices 1 and a synchronization axis 17 for synchronizing the ejection devices 6 of both ejection devices 1.

[0069] The release devices 13 of both ejector devices 1 are able to contact both locking devices 9 of both ejector devices 1 at different contact positions 37, 38, respectively, by contact contours 35 (indirectly linked via synchronization axis 17), and prior to unlocking, both locking devices 9 are in the first contact position 37 - representing the locked position 10.

[0070] In Figure 12b, the right-side protrusion device 6 has moved to the overpressure position 22, while the left-side protrusion device 6 remains in its initial position. This can occur, for example, when pressure is applied to one side of the movable furniture component 2. In the absence of the synchronization axis 17, the left-side protrusion device 1 can be indirectly activated via the movable furniture component 2 when the right-side protrusion device 1 has already been unlocked and is moving further in the opening direction 7, thereby pulling the left-side protrusion device 6 together. In this embodiment, when the right-side locking device 9 is unlocked, the left-side locking device 9 is also unlocked by the synchronization axis 17, thereby initiating synchronized unlocking.

[0071] Figure 12c illustrates this situation, where the lever 14 of the right-side projection device 1 is coupled to the locking device 9 via a second contact position 38, while the lever 14 on the left side remains at the first contact position 37. The second contact position 38 is suitable for inducing unlocking in interaction with the locking device 9, based on the shape or geometry of the lever 14.

[0072] Figures 12d and 12e show the transition of both locking devices 9 to an unlocked state for the release of both ejecting devices 6 or the involved control devices 12, with the ejecting devices 6 being unlocked in parallel in the opening direction 7 by the synchronization axis 17.

[0073] In principle, both ejection devices 6 can be unlocked by pulling (in the opening direction 7) or by pressing (in the closing direction 11). The specific position of the lever 14 can trigger the unlocking and synchronization of the ejection device 1.

[0074] Figure 12f shows the state of both ejection devices 1 after the synchronization of the unlocking of both locking devices 9 has been completed, and an exemplary method for synchronizing the two ejection devices 1 can be described as follows: -The release devices 13 of the first and second ejection devices 1 move to the closed position 3, and at least two release devices 13 contact the two locking devices 9 at the same contact position 37. -The release device 13 of the first ejection device 1 moves from the closed position 3 to the overpressed position 22, and from the overpressed position 22 back to the closed position 3, and the release device 13 of the first ejection device 1 contacts the locking device 9 of the first ejection device 1 at a different, altered contact position 38 relative to the first contact position 37, thereby causing the locking device 9 to pivot in order to activate the ejection device 6 of the first ejection device 1. - The synchronization shaft transmits the rotational motion of the locking device 9 of the first ejection device 1 to the locking device 9 of the second ejection device 1, causing the locking device 9 of the second ejection device 1 to rotate and release the ejection device 6 of the second ejection device 1.
