Description

Technical Field

[0001] This invention relates to an accessory designed as a furniture or structural component, wherein the accessory is used to connect two furniture or structural elements to each other, and the accessory comprises: - At least one matrix, - At least one adjusting element, which is mounted in a movable manner relative to the base. - At least one adjusting device for adjusting the relative position between a base and an adjusting element, wherein the at least one adjusting device includes at least one eccentric wheel rotatable about a rotation axis, wherein the relative position between the base and the adjusting element can be adjusted by rotation of the at least one eccentric wheel about the rotation axis. - A circumferential adjustment profile disposed on the at least one eccentric wheel, wherein the circumferential adjustment profile operates on at least one mating profile as the eccentric wheel rotates about a rotation axis.

[0002] Furthermore, the present invention relates to a configuration comprising at least two furniture elements or structural elements and at least one accessory of the type to be described. Prior Technology

[0003] For example, DE 20 2007 014 368 U1 discloses a similar type of fitting. This fitting is designed as a furniture hinge and has two hinge arm components that can be adjusted relative to each other in the longitudinal direction of their hinge arms by means of an eccentric wheel.

[0004] By using an eccentric wheel, rotational motion can be converted into linear motion of the structural component to be adjusted. The eccentric wheel's axis of rotation is at a certain distance from the imaginary geometric center. Through the special shape design of the eccentric wheel, a small effective lever arm is formed between the eccentric wheel's axis of rotation and the force application point of the adjusting element. A smaller eccentricity produces a smaller effective lever arm, yet a larger force can be applied to the structural component to be adjusted.

[0005] This also demonstrates the advantage of eccentric wheels: they can rotate freely without hindering or preventing their own rotational movement. Due to this unimpeded rotational capability, there is virtually no risk of the eccentric wheel rotating too fast or being damaged by it or other structural components of the accessory.

[0006] However, due to the eccentric arrangement of the rotating shaft, the force is transmitted laterally to the rotating shaft of the eccentric wheel. Therefore, there is a certain uncertainty in the locking of the eccentric wheel relative to the mating profile; that is, unexpected adjustments may occur between the base and the adjusting element, resulting in sudden and spontaneous displacement. Summary of the Invention

[0007] Therefore, the object of the present invention is to provide an accessory of the type described at the beginning of this document, which avoids the above-mentioned disadvantages.

[0008] According to the invention, this is achieved by the features of claim 1. Other advantageous embodiments of the invention are further defined in the appendix.

[0009] According to the present invention, the circumferential adjustment profile of the at least one eccentric wheel and / or the at least one mating profile have a macroscopic surface structure in at least certain areas to improve the self-locking performance.

[0010] The macroscopic, visible surface structure improves the self-locking performance of the eccentric wheel, ensuring that its pre-set rotational position remains unchanged without additional operation. This significantly reduces the risk of accidental or sudden displacement of the eccentric wheel.

[0011] Macroscopic surface structures may include, for example, ribs, bumps, grooves, tips, protrusions, corrugations, teeth, depressions, or combinations of these elements.

[0012] Another advantage of the macroscopic surface structure is that the eccentric wheel can only rotate after overcoming a predetermined holding force, thus enabling fine adjustment of the eccentric wheel. In addition, the macroscopic surface structure can produce a clicking sound, which is a kind of audible feedback to the user about the degree of setting.

[0013] According to one embodiment, the eccentric wheel is installed in a rotatable manner without any limiting device to impede its rotation. Therefore, the eccentric wheel can be freely driven by a rotating tool without damaging the eccentric wheel or other structural components of the adjusting device.

[0014] According to another embodiment, the substrate and / or eccentric wheel are made of a preferred glass fiber reinforced plastic material. This allows for the simple and cost-effective production of these structural components. This production can be accomplished, for example, by injection molding, while enabling the manufacture of complex shapes of the substrate and / or eccentric wheel at high frequencies.

[0015] According to another embodiment, an eccentric wheel is arranged between and cooperates with two opposing mating profiles, wherein a macroscopic surface structure is provided only on one of the two mating profiles. Preferably, the other of the two mating profiles is smooth. In this way, the eccentric wheel can rotate with a set retaining force without getting stuck between the two mating profiles.

[0016] According to another embodiment, the macroscopic surface structure extends over the entire periphery of the eccentric wheel and / or the entire width of the substrate. This stabilizes the eccentric wheel in its position and reduces the risk of lateral tipping, especially during lateral position adjustment of the eccentric wheel. Simple Explanation of the Diagram

[0017] Further details and advantages of the invention will be revealed from the following figures.

[0019] Figures 2a and 2b show cross-sectional views of the drawer and corresponding enlarged detail views.

[0020] Figures 3a and 3b show perspective views of the front area of ​​the drawer and the fittings that can be connected to the connecting device.

[0021] Figures 4a-4c show two different views of the accessory and a perspective view of the eccentric wheel.

[0022] Figures 5a and 5b show two views of the base with an eccentric wheel. Implementation

[0023] Figure 1a shows a perspective view of furniture 1, which includes a furniture body 2 and furniture components 3 movably mounted relative to the furniture body 2. In the illustrated embodiment, the furniture components 3 are all designed as drawers, which are movably mounted relative to the furniture body 2 by means of drawer pull-out guide devices 5 (Figure 1a).

[0024] Furniture component 3 includes two or more furniture elements 3a, 3b, and 3c, wherein furniture element 3a can be a drawer front panel, furniture element 3b can be a drawer side wall, and furniture element 3c can be a drawer back wall.

[0025] Furniture element 3b, in the form of a drawer sidewall, can be transversely connected to furniture element 3a and furniture element 3c.

[0026] Figure 1b shows a perspective view of a movable furniture component 3 in the form of a drawer. The movable furniture component 3 may include a drawer bottom plate 4, which is connected to or can be attached to furniture components 3a, 3b, and 3c.

[0027] The drawer pull-out guide 5 for movably mounting the movable furniture component 3 includes a main guide rail 6 to be fixed to the furniture body 2 and at least one pull-out guide rail 7 movable relative to the main guide rail 6, wherein the movable furniture component 3 is connected to or releasably connected to the pull-out guide rail 7.

[0028] Figure 2a shows a cross-sectional view of a movable furniture component 3 in the form of a drawer. Furniture element 3b in the form of a drawer sidewall is connected to furniture element 3a in the form of a drawer front panel via a front bracket 8, and to furniture element 3c in the form of a drawer rear wall via a rear bracket 9.

[0029] The present invention will be explained below using the front support 8 as an example.

[0030] The drawer sidewall-shaped furniture element 3b is preferably a hollow cavity profile, preferably made of metal, and a connecting device 11 is inserted into the front end of the hollow cavity profile. The connecting device 11 is used to releasably connect the drawer front panel-shaped furniture element 3a.

[0031] The connecting device 11 includes a locking device 12 with a gripping element 12b in the form of a preferred rocker arm, which is loaded by a spring 12a.

[0032] A fitting 10 can be pre-installed on furniture element 3a in the form of a drawer front panel, wherein the fitting 10 is designed to be releasably locked with the locking device 12 of furniture element 3b.

[0033] Accessory 10 includes a fastening element 13, for example, in the form of a snap screw, wherein when the fastening element 13 bites into the notch 20 of the gripping element 12b (Figure 2b), the fastening element 13 can be releasably locked with the spring-loaded gripping element 12b.

[0034] Figure 2b shows an enlarged view of the area framed in Figure 2a.

[0035] The accessory 10, which needs to be fixed to the furniture element 3a, includes at least one adjustment device 14 with a rotatable eccentric wheel 15, wherein the height position of the furniture element 3a relative to the furniture element 3b can be adjusted by rotating the eccentric wheel.

[0036] In the illustrated embodiment, the accessory 10 includes at least one additional adjustment device 16 with a rotatable adjustment element 16a, wherein the lateral position of the furniture element 3a relative to the furniture element 3b can be adjusted by rotating the adjustment element 16a. The adjustment directions of the two adjustment devices 14, 16 are transverse to each other.

[0037] Figure 3a shows the front area of ​​the drawer-shaped movable furniture component 3, while the drawer-side furniture element 3b is not shown for clarity. Therefore, the front support 8 for connecting the two furniture elements 3a and 3b is clearly visible, wherein the connecting device 11 is releasably coupled to the fitting 10 by means of the locking device 12.

[0038] Figure 3b shows the front support 8, and the connecting device 11 and accessory 10 in a separated state. The connecting device 11 includes a locking device 12 with a movable, preferably pivotable, gripping element 12b preloaded by a spring 12a.

[0039] The gripping element 12b includes a slit-shaped notch 20 for releasably receiving the retaining element 13 of the accessory 10. In the ready position, the notch 20 faces the retaining element 13, wherein the gripping element 12b is triggered by the retaining element 13 entering the notch 20. Then, the retaining element 13 can be pulled into the locked position by pivoting the gripping element 12b and by the force of the spring 12a.

[0040] The locking state between the fixing element 13 and the gripping element 12b can be released again by using the release element 17. By rotating the release element 17 with a screwdriver, the force of the spring 12a can be overcome to reset the gripping element 12b, thereby allowing the fixing element 13 and the gripping element 12b to separate from each other.

[0041] The accessory 10 includes at least one base 18, at least one adjustment element 19 movably mounted relative to the base 18, and at least one adjustment device 14, the at least one adjustment device 14 having a rotatable eccentric wheel 15 for adjusting the relative position between the base 18 and the adjustment element 19.

[0042] Figure 4a shows accessory 10 in an exploded view. Accessory 10 includes a base 18 and at least one adjustment element 19 that is adjustable relative to the base 18.

[0043] The base 18 may include at least one contact surface 26 for abutting against furniture elements 3a-3c and / or at least one fixing position 30a, 30b (Figure 4b) for fixing the base 18 to the furniture elements 3a-3c. The at least one fixing position 30a, 30b may include, for example, a hole for a screw to pass through and / or at least one fixing pin.

[0044] At least one adjusting device 14 for adjusting the relative position between the base 18 and the adjusting element 19 includes at least one eccentric wheel 15 rotatable about a rotation axis 21, wherein the relative position between the base 18 and the adjusting element 19 can be adjusted by the rotation of the at least one eccentric wheel 15 about the rotation axis 21.

[0045] In the illustrated embodiment, the height position between the base 18 and the adjusting element 19 can be adjusted by rotating the eccentric wheel 15.

[0046] The eccentric wheel 15 includes a circumferential adjustment profile 23, which operates on at least one mating profile 29a as the eccentric wheel 15 rotates about the rotation axis 21.

[0047] At least one eccentric wheel 15 has a circumferential adjustment profile 23 and / or at least one mating profile 29a with a macroscopic surface structure 23a in at least certain areas to improve self-locking performance.

[0048] The macroscopic surface structure 23a may have elements such as ribs, bumps, grooves, tips, protrusions, corrugations, teeth, depressions, or combinations thereof.

[0049] In the illustrated embodiment, the macroscopic surface structure 23a has a plurality of ribs arranged parallel to each other on the adjustment profile 23 of the eccentric wheel 15, wherein the longitudinal direction of the ribs is parallel to the rotation axis 21 of the eccentric wheel 15.

[0050] The macroscopic surface structure 23a can extend to cover the entire periphery of the eccentric wheel 15 and / or the entire width of the base 18. A particular benefit of this is that it reduces the risk of tipping between the base 18 and the eccentric wheel 15, especially when operating the adjusting element 16a of another adjusting device 16 for lateral adjustment.

[0051] At least one mating profile 29a may be arranged on the base 18. In the view shown, at least one mating profile 29a is arranged on the elastic structural member 31 of the base 18, preferably on the fork-shaped portion 31a.

[0052] Another adjustment device 16 includes an adjustment element 16a that can rotate about a rotation axis 22, wherein the rotation axis 21 of the eccentric wheel 15 is parallel to the rotation axis 22 of the adjustment element 16a.

[0053] In the illustrated embodiment, the lateral position between the base 18 and the adjusting element 19 can be adjusted by rotating the adjusting element 16a. The adjusting element 16a includes a threaded section 24, along which the rod 25 of the base 18 can be guided.

[0054] The adjusting element 19 has two side rods 27a and 27b spaced apart from each other, wherein the adjusting element 16a of the eccentric wheel 15 and / or another adjusting device 16 is arranged between the two side rods 27a and 27b of the adjusting element 19.

[0055] The two side rods 27a and 27b of the adjusting element 19 each have circular openings 28a and 28b for mounting the eccentric wheel 15 and the adjusting element 16a. Therefore, the eccentric wheel 15 and the adjusting element 16a are mounted on the adjusting element 19 in a manner that prevents axial movement. The adjusting element 19 may at least partially surround the base 18.

[0056] The base 18 and the adjusting element 19 have different widths in the direction of the rotation axis 21 of the eccentric wheel 15. In this way, the base 18 can be adjusted laterally upward inside the adjusting element 19 by rotating the adjusting element 16a.

[0057] Figure 4b shows the accessory 10 in a cross-sectional view, showing the eccentric wheel 15 for height adjustment and the adjustment element 16a for lateral adjustment, both located between the base 18 and the adjustment element 19.

[0058] The eccentric wheel 15 is mounted in a rotatable manner without any limiting device to hinder its rotation. As can be seen, it is arranged on the elastic structural member 31 with the matching profile 29a, so that the elastic structural member 31 alternately overcomes the elastic effect and displaces during the rotation of the eccentric wheel 15 and springs back under the accumulated energy.

[0059] In the illustrated embodiment, the eccentric wheel 15 is arranged between and in cooperation with two opposing mating profiles 29a, 29b, wherein a macroscopic surface structure 23a is provided on only one of the two mating profiles 29a, 29b, preferably the other mating profile 29b is smooth.

[0060] Since the eccentric wheel 15 can rotate freely, it is practically impossible for it to be damaged due to excessive torque. Therefore, it is sufficient if the base 18 and / or the eccentric wheel 15 are made of a plastic material that is preferably reinforced with glass fiber.

[0061] Therefore, the base 18 and the eccentric wheel 15 can be manufactured by an injection molding process, in which complex shapes can be easily and cost-effectively manufactured, while carbon emissions are improved.

[0062] Figure 4c shows the eccentric wheel 15 in perspective, with a macroscopic surface structure 23a arranged on the circumferential adjustment profile 23.

[0063] The eccentric wheel 15 includes a cylindrical support surface 32 in certain areas for rotatably supporting the eccentric wheel 15, wherein the support surface 32 is accommodated in the circular opening 28a (Figure 4a) of the adjusting element 19 in the installed state.

[0064] The eccentric wheel 15 includes a socket 33 for rotating a tool at at least one end, preferably at both ends, so that the eccentric wheel 15 can be rotated by rotating the socket 33 with a tool.

[0065] Figure 5a shows the base 18 together with the eccentric wheel 15 of the adjusting device 14 in a side view. The eccentric wheel 15 is housed in the U-shaped or fork-shaped portion 31a of the base 18, and its opposite sides abut against the two legs of the U-shaped or fork-shaped portion 31a.

[0066] As can be seen, the mating contour 29a of the elastic structural component 31 has a macroscopic surface structure 23a, which works in conjunction with the macroscopic surface structure 23a of the eccentric wheel 15.

[0067] Preferably, the other mating profile 29b of the substrate 18 is not macroscopically surface-structured 23a and is therefore smooth.

[0068] According to one possible embodiment, the eccentric wheel 15 is substantially triangular in cross-section, preferably wherein the three sides of the substantially triangular eccentric wheel 15 are substantially the same length. This ensures uniform force transmission from the eccentric wheel 15.

[0069] Figure 5b shows the base 18 together with the eccentric wheel 15 in an exploded view.

[0070] The accessory 10 shown and described may, for example, be designed as a bracket 8 (Figure 2a) for fixing the front panel of the drawer to the side wall of the drawer, a bracket 9 (Figure 2a) for fixing the rear wall of the drawer to the side wall of the drawer, a hinge for movably mounting the furniture component 3, or be designed as a drawer pull-out guide device.
