DETAILED DESCRIPTION OF THE INVENTION

[0028] FIG. 1a shows a perspective view of a drawer 1 comprising drawer sidewalls 2, a front panel 3 to be connected to the drawer sidewalls 2, a drawer bottom 4 and a rear wall 5.

[0029] Each of the drawer sidewalls 2 includes a connecting device 6 for, preferably releasably, connecting the front panel 3 to the drawer sidewall 2. Each of the drawer sidewalls 2 includes a hollow profile 8, preferably made of metal, in which the connecting device 6 can be at least partially, preferably substantially entirely, arranged.

[0030] The drawer sidewall 2 includes a front face 7 facing towards the front panel 3, and the connecting device 6, in a connected condition between the drawer sidewall 2 and the front panel 3, at least partially contacts a rear side of the front panel 3, the rear side of the front panel 3 facing towards the drawer side wall 2.

[0031] The drawer 1 is displaceably supported relative to a furniture carcass (not shown here) via a drawer pull-out guide 9. The drawer pull-out guide 9 includes a carcass rail 10 configured to be fixed to a furniture carcass, and at least one extension rail 11 movable relative to the carcass rail 10. The drawer 1 can be releasably coupled to the extension rail 11 of the drawer pull-out guide 9 via a coupling device 18 (FIG. 2a) which is yet to be described.

[0032] The drawer 1 includes at least one rear wall 5 to be arranged in a direction extending parallel to the front panel 3. The drawer sidewall 2 can include at least one rear wall holder 12 for, preferably releasably, connecting the rear wall 5 to the drawer sidewall 2.

[0033] FIG. 1b shows the framed region of FIG. 1a in an enlarged view.

[0034] FIG. 1c shows a holding portion 13 which is to be fixed to the rear side of the front panel 3, for example via screws 14 and/or dowels.

[0035] FIG. 1d shows the holding portion 13 fixed to the rear side of the front panel 3. The connecting device 6 can advantageously include a locking device 29 (FIG. 5) for releasably locking the holding portion 13 to the drawer sidewall 2.

[0036] FIG. 2a shows the drawer sidewall 2 in a perspective view from above, in which the drawer sidewall 2 can be releasably coupled to the extension rail 11 of the drawer pull-out guide 9 via a coupling device 18. In the shown embodiment, the coupling device 18 includes a coupling element 18a arranged on the drawer sidewall 2, the coupling element 18a being configured to be releasably coupled to a coupling lever 18b of the extension rail 11. In the shown FIG. 2a, the uncoupled condition between the coupling element 18a and the coupling lever 18b is illustrated.

[0037] The coupling device 18 with the coupling element 18a and the connecting device 6 for, preferably releasably, connecting the front panel 3 to the drawer sidewall 2 are combined to a common constructional unit.

[0038] The coupling lever 18b for releasably coupling to the coupling element 18a is pivotally supported on the extension rail 11 so as to be bendable or so as to be pivotable about a vertically extending axis in the mounted position.

[0039] The drawer pull-out guide 9 can include a height adjustment device 17 having a movable actuating element 17a, and a height position of the drawer 1 with respect to the extension rail 11 is adjustable by an actuation of the actuating element 17a.

[0040] In the rear region of the extension rail 11, a hook 15 is provided. The hook 15 is arranged with a predetermined distance to the upper side of the extension rail 11 and extends in a longitudinal direction L of the drawer sidewall 2. In a mounted condition of the drawer sidewall 2, the hook 15 is received within a hole 16 of the rear wall holder 12. The hook 15 defines a rear position of the drawer 1 on the extension rail 11. Moreover, the rear region of the drawer 1 can be stabilized in a direction extending transversely to the longitudinal direction L of the drawer sidewall 2 due to the hook 15 engaging into the hole 16.

[0041] FIG. 2b shows the framed region of FIG. 2a in an enlarged view. According to an embodiment, the drawer sidewall 2 is substantially cuboidal and/or is substantially rectangular seen in a cross-sectional plane extending perpendicular to the longitudinal direction L of the drawer sidewall 2.

[0042] The connecting device 6 for releasably connecting to the front panel 3 includes the coupling device 18 for releasably coupling the drawer sidewall 2 to the extension rail 11 of the drawer pull-out guide 9.

[0043] In the shown embodiment, the coupling device 18 includes at least one coupling element 18a arranged on the drawer sidewall 2, the coupling element 18a being configured to be releasably coupled to the coupling lever 18b.

[0044] In the shown figure, the coupling element 18a includes a bearing surface 19, a first abutment surface 20a extending in the longitudinal direction L and/or a second abutment surface 20b extending in a direction extending transversely to the longitudinal direction L of the drawer sidewall 2.

[0045] In the shown configuration, the bearing surface 19 is configured to bear against the drawer sidewall 2, the first abutment surface 20a is configured to bear against a vertical limb 23 of the extension rail 11, and the second abutment surface 20b is configured to bear against the coupling lever 18b. Due to the locking surfaces 22 arranged offset along a longitudinal direction L of the drawer sidewall 2, the drawer 1 can adopt different depth positions in a locked condition with the extension rail 11, so that the front side of the front panel 3 can be aligned substantially in a common plane with respect to adjacent front panels.

[0046] Of course, in a kinematic reversal, it is also possible that the coupling lever 18b is arranged on the connecting device 6 of the drawer sidewall 2, and the coupling element 18a is arranged on the extension rail 11.

[0047] Moreover, the coupling element 18a includes at least one inclined surface 20c configured to deflect the coupling lever 18b against a spring force in a direction extending transversely to the longitudinal direction L of the drawer sidewall 2 when the drawer sidewall 2 is coupled to the extension rail 11.

[0048] After deflection, the coupling lever 18b is automatically lockable to the coupling element 18a due to the accumulated spring force.

[0049] According to an embodiment, the drawer sidewall 2 includes a groove 24 extending in the longitudinal direction L of the drawer sidewall 2, the groove 24 being configured to receive an edge of the drawer bottom 4. The groove 24 can include an upper holding limb 24a and a lower holding limb 24b spaced apart from the upper holding limb 24a. The lower holding limb 24b extends substantially parallel to the upper holding limb 24a, and the edge of the drawer bottom 4 can be arranged between the upper holding limb 24a and the lower holding limb 24b.

[0050] Preferably, at least a side face of the drawer sidewall 2 is formed by an integral one-piece metal portion, and the groove 24, jointly with the two holding limbs 24a, 24b, is formed into the metal portion by bendings.

[0051] FIG. 3a shows the coupling of the drawer sidewall 2 in a further position of the drawer sidewall 2 relative to the extension rail 11.

[0052] By sliding the drawer sidewall 2 onto the extension rail 11 of the drawer pull-out guide 9, the coupling lever 18b is pivoted in a plane extending parallel to the running plane of the extension rail 11 due to the co-operation of the two inclined surfaces 20c, 21, and a force storage member for applying a force to the coupling lever 18b can be loaded thereby.

[0053] It can be seen that the front end of the extension rail 11 includes a limb 11a displaceably guided in a guide 25 of the coupling lever 18b. Preferably, the limb 11a descends in a direction towards the front. Due to the limb 11a engaging into the guide 25, the coupling lever 18b is precisely guidable in a lateral direction.

[0054] FIG. 3b shows the locked position between the drawer sidewall 2 and the extension rail 11. By a continued movement of the drawer sidewall 2 onto the extension rail 11, the coupling lever 18b can be releasably coupled to the coupling element 18a by the force of the relaxing force storage member. In the coupled condition, the first abutment surface 20a of the coupling element 18a bears against the vertical limb 23 of the extension rail 11 so as to stabilize the drawer sidewall 2 in a direction extending transversely to the longitudinal direction L.

[0055] For example, the coupling lever 18b can include a handle 26 configured for manual actuation, and the coupling between the drawer sidewall 2 and the extension rail 11 is releasable by the handle 26. By a manual actuation of the handle 26 against the resilient force of the coupling lever 18b, the coupling between the drawer sidewall 2 and the extension rail 11 is again releasable.

[0056] FIG. 4a shows the coupled condition between the coupling lever 18b and the coupling element 18a in a perspective view. In the shown embodiment, the coupling element 18a is arranged on a base body 6a of the connecting device 6, and the base body 6a is to be arranged in a front region of the drawer sidewall 2.

[0057] The coupling lever 18b with the locking surfaces 22 is supported on a flexure joint 27 which, with this embodiment, forms the force storage member for applying a force to the coupling lever 18b.

[0058] The coupling lever 18b includes the guide 25 for linearly guiding the limb 11a of the extension rail 11, the guide 25 extending transversely to the longitudinal direction L. The coupling lever 18b is connectable to the extension rail 11 of the drawer pull-out guide 9 via at least one fastening portion 28.

[0059] FIG. 4b shows a cross-sectional view of the coupling lever 18b arranged on the extension rail 11. It can be seen that the limb 11a of the extension rail 11 descends in a direction towards the front, and the coupling lever 18b is displaceably guided in a direction extending transversely to the longitudinal direction L via the limb 11a engaging into the guide 25.

[0060] FIG. 5 shows a possible embodiment of a connecting device 6 in an exploded view. The connecting device 6 includes a base body 6a, preferably made of plastic, to be arranged within the hollow profile 8 of the drawer sidewall 2. It can be seen that the coupling element 18a of the coupling device 18 is arranged on or within the base body 6a of the connecting device 6.

[0061] The connecting device 6 includes a groove 24 extending in the longitudinal direction L of the drawer sidewall 2, the groove 24 being configured to receive an edge of the drawer bottom 4.

[0062] According to preferred embodiments, the connecting device 6: [0063] includes at least one locking device 29 for releasably locking at least one holding portion 13 to be fixed to the front panel 3, preferably the locking device 29 including at least one, preferably spring-loaded and/or displaceably supported, locking element 29a, and/or [0064] includes at least one adjustment device 31 for adjusting a position of the front panel 3 relative to the drawer sidewall 2 at least in one direction, preferably in a direction extending transversely to a longitudinal direction L of the drawer sidewall 2, preferably the at least one adjustment device 31 including at least one eccentric 32, and/or [0065] is substantially entirely received, apart from the coupling device 18, within the drawer sidewall 2 in a mounted condition on the drawer sidewall 2, and/or [0066] includes a base body 6a, preferably the base body 6a being made of plastic and/or being configured substantially L-shaped.

[0067] In the shown embodiment, the locking device 29 includes a locking element 29a pressurized by a spring element 29b, the locking element 29a having a notch 30 configured to receive a bolt 13a of the holding portion 13. When the bolt 13a is introduced into the notch 30, the locking element 29a is moved in an upward direction by the inclined surface 33 against the force of the spring element 29b, and the bolt 13a is subsequently lockable in the notch 30.

[0068] The adjustment device 31 can include a rotatable adjustment element 31a having at least one eccentric 32 which can be arranged between the two side limbs of the holding portion 13 extending parallel to each other. By rotating the adjustment element 31a, the holding portion 13 (and therewith the front panel 3) is adjustable in a lateral direction relative to the base body 6a.

[0069] FIG. 6a shows the drawer sidewall 2 with the hollow profile 8 in a perspective view from below. In the shown figure, the holding portion 13 to be fixed to the front panel 3 is locked with the locking device 29 of the connecting device 6.

[0070] FIG. 6b shows the framed region of FIG. 6a in an enlarged view, in which the front-end region of the drawer sidewall 2 emerges in greater detail. The coupling element 18a of the coupling device 18 is provided for releasably coupling to the extension rail 11 of the drawer pull-out guide 9.

[0071] The locking element 29a of the locking device 29 projects from the drawer sidewall 2 in a downward direction. The locking between the holding portion 13 and the locking element 29 is releasable by applying pressure to the locking element 29.

[0072] The adjustment element 31a of the adjustment device 31 includes a receiver for a tool, and a position of the holding portion 13 is adjustable in a direction extending transversely to the longitudinal direction L of the drawer sidewall 2 by rotating the adjustment element 31a.

[0073] FIG. 7a-7c show the releasable coupling of the holding portion 13 to be fixed to the front panel 3 with the locking device 6 in temporally subsequent steps.

[0074] FIG. 7a shows the holding portion 13 with the bolt 13a configured to be releasably locked, upon inserting, with the locking element 29a of the locking device 29.

[0075] FIG. 7b shows that the locking element 29a is moved against the force of the spring element 29b when the bolt 13a abuts against the inclined surface 33 of the locking element 29a. The spring element 29b can be a compression spring. Therefore, the locking element 29a is thus moved in an upward direction against the force of the spring element 29b.

[0076] FIG. 7c shows that the bolt 13a of the holding portion 13 is locked by the force of the relaxing spring element 29b. In a locked condition, the bolt 13a of the holding portion 13 is located within the notch 30 of the locking element 29.

[0077] FIG. 8a shows a further embodiment of a drawer sidewall 2 which is coupled to the extension rail 11 of the drawer pull-out guide 9 via a coupling device 18. The carcass rail 10 of the drawer pull-out guide 9 includes a fastening portion 10a for fixing the carcass rail 10 to a furniture carcass. The drawer sidewall 2, in a coupled condition, is arranged between the fastening portion 10a of the carcass rail 10 and a vertical limb 23 of the extension rail 11.

[0078] In the shown embodiment, the connecting device 6 includes a coupling device 18 having a pivotable coupling lever 18b. The coupling lever 18b is configured to be releasably coupled to the extension rail 11 of the drawer pull-out guide 9.

[0079] FIG. 8b shows the framed region of FIG. 8a in an enlarged view. The coupling lever 18b is pivotally supported on the drawer sidewall 2 about a vertically extending axis 34 (FIG. 9) and projects transversely from an inner side face of the drawer sidewall 2.

[0080] The coupling lever 18b can include two or more locking surfaces 22 arranged offset relative to each other along a longitudinal direction L of the drawer sidewall 2. Due to the different locking surfaces 22, the drawer sidewall 2 is lockable in two or more depth positions with respect to the extension rail 11. In this way, the depth position of the drawer 1 relative to a furniture carcass is also adjustable. It can be seen that one of the locking surfaces 22 bears against an edge 23a of the vertical limb 23 of the extension rail 11.

[0081] FIG. 9 shows the embodiment of the connecting device 6 of the drawer sidewall 2 according to FIGS. 8a, 8b in an exploded view. With this embodiment, the coupling lever 18b is pivotally supported about an axis 34 on the base body 6a, preferably on an underside of the base body 6a. The coupling lever 18b can be pressurized by a spring 35 for pressing the coupling lever 18b in a direction of a coupling position.

[0082] With regard to the other functionalities of the connecting device 6, reference is made to the embodiment according to FIG. 5.

[0083] FIG. 10a shows the connecting device 6 according to FIG. 9 in a perspective view from below. The coupling lever 18b is pivotally supported about the axis 34 and is pressurized by the spring 35 in a direction of the coupling position. The spring 35, as shown, can be formed by a material elasticity of a plastic member or, alternatively, by a mechanical spring element (for example by a tension spring, a compression spring or a torsion spring). For the sake of overview, the extension rail 11 is not depicted.

[0084] FIG. 10b shows the framed region of FIG. 10a in an enlarged view, in which the coupling lever 18b is located in an unlocking position.

[0085] FIG. 10c shows the coupling lever 18b in a coupling position which is established by the force of the spring 35.

[0086] FIG. 11a-11d show the coupling operation of the connecting device 6 according to FIGS. 10a-10c in temporally subsequent steps.

[0087] FIG. 11a shows the coupling lever 18b pivotally supported about the axis 34 on the base body 6a, the coupling lever 18b being pressurized by the spring 35 in a direction of the coupling position. The coupling lever 18b is to be connected to the extension rail 11 of the drawer pull-out guide 9, and the extension rail 11 includes a vertical limb 23 and an edge 23a configured to bear against the coupling lever 18b. Further, the extension rail 11 includes an abutment 36 configured to deflect the coupling lever 18b against the force of the spring 35. In this way, the spring 35 can be loaded.

[0088] FIG. 11b shows the coupling lever 18b abutting against the abutment 36 of the extension rail 11 when the drawer sidewall 2 is slid onto the extension rail 11. In this way, the coupling lever 18b is pressed against the force of the spring 35.

[0089] FIG. 11c shows that the tensioned coupling lever 18b is movable along an outer side of the vertical limb 23 of the extension rail 11 upon a further sliding movement of the drawer sidewall 2 onto the extension rail 11.

[0090] FIG. 11d shows that the spring-loaded coupling lever 18b enters into a recess of the extension rail 11, and the coupling lever 18b is pressed into the coupling position by the force of the relaxing spring 35. In the coupling position, the locking surface 22 of the coupling lever 18b and an edge 23a of the extension rail 11 mutually bear against each other so as to prevent a relative movement between the drawer sidewall 2 and the extension rail 11.

[0091] FIG. 12a-12e show the unlocking operation of the connecting device 6 according to FIG. 10a-10c in temporally subsequent steps.

[0092] FIG. 12a shows the coupled position between the coupling lever 18b and the extension rail 11, in which the coupling lever 18b bears against the edge 23a of the extension rail 11.

[0093] FIG. 12b shows that the drawer sidewall 2 has to be manually lifted by the height x so as to release the coupling lever 18b from the edge 23a of the extension rail 11.

[0094] FIG. 12c shows that the drawer 1 has been pulled by an operator in the extension direction 38 by the distance s. The coupling lever 18b has thereby been moved through a first gap 37a extending in the longitudinal direction L of the extension rail 11.

[0095] FIG. 12d shows that the drawer 1 is lowered by the height x1 by manually pressing the drawer sidewalls 2 of the drawer 1 in a downward direction.

[0096] FIG. 12e shows that the drawer 1 has further been moved in the extension direction 38. The coupling lever 18b is movable through a second gap 37b of the extension rail 11, the second gap 37b extending in the longitudinal direction L. After the coupling lever 18b has been moved through the second gap 37b of the extension rail 11, the drawer sidewall 2 and the extension rail 11 can be separated from each other.

[0097] The method for coupling a drawer sidewall 2 of the type in question to an extension rail 11 of a drawer pull-out guide 9 is characterized in that the drawer sidewall 2 is releasably coupled to the extension rail 11 by virtue of the coupling device 18.

[0098] According to a further embodiment of the method, the drawer sidewall 2, for coupling, is moved substantially parallel to a longitudinal direction L of the extension rail 11 and/or the coupling device 18 includes a spring-loaded coupling lever 18b which is urged against the resilient action upon coupling.

[0099] According to a further embodiment of the method, the drawer sidewall 2, for decoupling from the drawer pull-out guide 9, is manually lifted from the connected condition, subsequently moved in the extension direction 38, subsequently lowered, and subsequently moved again in the extension direction 38.

[0100] FIG. 13a-13c show a further embodiment of a drawer sidewall 2 in different views.

[0101] FIG. 13a shows a perspective view of the drawer sidewall 2 in the form of a hollow profile 8. The holding portion 13 (FIG. 1c, FIG. 1d) to be locked to the locking device 29 is to be fixed to the front panel 3 via at least one screw 14. The holding portion 13 is releasable by pressing the locking element 29a against the force of a spring 29b (FIG. 5).

[0102] The drawer sidewall 2 includes a groove 24 for partially receiving the drawer bottom 4, the groove 24 extending in the longitudinal direction L. The drawer bottom 4 is fixable in a force-locking manner within the groove 24 of the drawer sidewall 2 via at least one fastening element 40, for example in the form of at least one clamp.

[0103] The coupling lever 18b is pivotally supported about a pivoting axis 42 (FIG. 14a, FIG. 14b) extending vertically in the mounted position. By a return device 39, the at least one coupling lever 18b can be returned from a coupling position into a release position.

[0104] According to preferred embodiments: [0105] the return device 39 includes at least one slider 39a displaceably supported in a longitudinal direction L of the drawer sidewall 2, and/or [0106] the return device 39 includes at least one return contour 39b (FIG. 14a, FIG. 14b) configured to urge the at least one coupling lever 18b from the coupling position into the release position, and/or [0107] the return device 39 includes at least one handle element 41 projecting from the drawer sidewall 2 in a downward direction, in particular when the drawer sidewall 2 is in a mounted position.

[0108] FIG. 13b shows a partial portion of the drawer sidewall 2 in a view from below, in which the coupling lever 18b is located in a coupling position with the extension rail 11 (not shown here) of the drawer pull-out guide 9. By virtue of a slider 39a linearly displaceable in the longitudinal direction L, the coupling lever 18b is movable from the coupling position according to FIG. 13b in a release position, as shown in FIG. 13c.

[0109] FIG. 13c shows a partial portion of the drawer sidewall 2 in a view from below, in which the coupling lever 18b is located in the release position.

[0110] Due to the slider 39a to be actuated by at least one handle element 41, preferably by two handle elements 41, a conscious decoupling of the coupling lever 18b from the extension rail 11 of the drawer pull-out guide 9 can be provided. The at least one handle element 41 and the slider 39a can be formed together so as to have an integral one-piece configuration and/or is directly accessible for manual actuation. It is also possible that the slider 39a and the at least one handle element 41 are configured as components separate from each other, and are connected to each other in a motionally-connected manner.

[0111] The coupling lever 18b can be pre-stressed by at least one spring 35 (FIG. 10a-10c) in a direction of the locking position so as to provide a defined unlocking of the coupling lever 18b by a movement of the slider 39a against a force of the spring 35.

[0112] FIG. 14a shows the connecting device 6 of the drawer sidewall 2 according to FIGS. 13a-13c. The coupling lever 18b of the coupling device 18 is pivotally supported about a pivoting axis 42 on the base body 6a. By a linear movement of the slider 39a of the return device 39, the coupling lever 18b can be urged from the coupling position according to FIG. 14a into the release position according to FIG. 14b. For this purpose, the return device 39 can include at least one return contour 39b for urging the at least one coupling lever 18b from the coupling position in a direction of the release position.

[0113] FIG. 14b shows the connecting device 6 according to FIG. 14a, in which the coupling lever 18b is located in a release position with respect to the extension rail 11 (not shown here) of the drawer pull-out guide 9.

[0114] FIG. 15a shows a side view of the connecting device 6 according to a slightly modified embodiment, in which the holding portion 13 is locked to the connecting device 6 via the locking device 29 including the locking element 29a. It can be seen that a spring element 43, for example in the form of a spring tongue, is arranged on the slider 39a of the return device 39. The spring element 43 ensures the correct position of the slider 39a relative to the base body 6a of the connecting device 6, and the slider 39a bears against the coupling lever 18b of the coupling device 18 by a force of the spring element 43.

[0115] FIG. 15b shows the framed region B of FIG. 15a in an enlarged view.

[0116] FIG. 15c shows a cross-sectional view along the plane C-C depicted in FIG. 15b. It can be seen that the slider 39a of the return device 39 includes a first return contour 39b and the coupling lever 18b of the coupling device 18 includes a second return contour 39c. The first return contour 39b and the second return contour 39c run along each other upon a movement of the coupling lever 18b between the coupling position and the release position. Each of the first return contour 39b and the second return contour 39c can be curved-shaped. The coupling lever 18b is pre-stressed by a spring 35, for example in the form of a leaf spring, in a direction of the coupling position.

[0117] When the slider 39a is pulled in the extension direction of the drawer 1, the coupling lever 18b is moved, due to the mutually co-operating return contours 39b, 39c, in a direction of the release position so that the drawer 1 can be unlocked from the drawer pull-out guide 9. The force of the spring element 43 is dimensioned weaker than the force of the spring 35.
