Description

Technical Field

[0001] This invention relates to a fixing device as described in the preamble of claim 1 for securing at least one flat drawer element—preferably a drawer back wall and / or drawer bottom—to a drawer side frame. Furthermore, this invention relates to a configuration comprising at least one flat drawer element, at least one drawer side frame, and at least one such fixing device, and a method for securing at least one flat drawer element to the drawer side frame by means of at least one such fixing device. Finally, this invention also relates to a drawer and a piece of furniture. Prior Technology

[0002] The applicant's PCT / AT2024 / 060246 discloses a fixing device. Its disadvantage is that the drawer element must be precisely engaged with the fixing area of ​​the drawer side frame. Because the bottom claws embed themselves into the material of the drawer element like barbs during engagement, it is impossible or difficult to correct deviations from the target position. Another disadvantage is that the drawer side frame is designed to fix drawer elements with predetermined characteristics. Drawer elements with characteristics deviating from these may not be able to be fixed to the drawer side frame as ideally.

[0003] KR 101818690 B1 and DE 202008006607 U1 disclose other fixing devices. Summary of the Invention

[0004] The object of this invention is to at least partially eliminate the known disadvantages of the prior art and to provide an improved fixing device, the main feature of which is that it can correct for errors during the connection process and / or can firmly fix drawer elements with different characteristics to the drawer side frame. A further object of this invention is to provide a configuration comprising at least one flat drawer element, at least one drawer side frame, and at least one such improved fixing device, and a method for fixing at least one flat drawer element to the drawer side frame by means of at least one such improved fixing device. Ultimately, this invention provides an improved drawer and an improved piece of furniture.

[0005] This objective is achieved through the features of requests 1, 8, 12, 13, and 14.

[0006] Therefore, the fixing device is designed as follows: the fixing device includes at least one mounting base, the at least one locking device being retractable into the at least one mounting base when engaged, wherein the mounting base includes at least one space of movement transverse to the engagement direction, such that the edge of the drawer element can move in a limited manner in an adjustment direction transverse to the access direction after engagement, and / or The at least one locking device comprises at least one fastening portion that can be accommodated in the mounting base, a base, and a portion between the two, the portion being flexible in at least certain areas, allowing the fastening portion to move relative to the base in a limited manner along an adjustment direction transverse to the engagement direction. These two measures, used alone or in combination, can correct errors that occur during engagement afterward. In PCT / AT2024 / 060246, the drawer element, after engagement, can no longer move, or can only move, transversely to the engagement direction under the application of a large force. There is a risk that the surface of the drawer element in contact with the bottom claws will continue to be damaged, which may further weaken the fixation of the drawer element to the drawer side frame.

[0007] According to an advantageous embodiment, the fixing device is designed such that the at least one locking device includes at least one mounting device, by which the at least one locking device can be mounted on and / or within a flat drawer element, preferably mounted on the bottom surface, back surface, and / or end face facing the drawer side frame in the use position. In this way, different numbers of locking devices can be flexibly and accurately equipped for the drawer element and / or these locking devices can be arranged in specific positions according to the characteristics of the drawer element and / or the retaining force requirements of the drawer element. In contrast, in PCT / AT2024 / 060246, the bottom claw is integrally and immutably provided on the drawer side frame.

[0008] Alternatively or as a supplement, the locking device may include at least one—preferably resilient—locking element, preferably wherein the locking element includes at least one bevel that is displaceable when the edge of the drawer element engages the at least one fixing area along a joint direction intersecting the drawer side frame. These features, whether used alone or in combination, ensure particularly reliable fixation of the locking device and / or facilitate engagement of the drawer element into the fixing area.

[0009] Advantageously, the at least one locking device includes at least one resilient element—preferably facing the drawer side edge—which, after engagement, applies a force to the at least one locking device in the opposite engagement direction. This allows for the compensation of any possible tolerances.

[0010] If the at least one mounting base includes at least one space of movement transverse to the engagement direction, it is advantageous for the at least one mounting base to include an elongated hole, a narrow slit, or a groove. This design of the mounting base allows the edge of the drawer element to move particularly easily along the adjustment direction transverse to the engagement direction after engagement.

[0011] If the at least one locking device includes at least one mounting device, by which the at least one locking device can be mounted on and / or within a flat drawer element, then the at least one mounting device includes at least one mounting tab, preferably pointed and / or with a barbed profile, and / or at least one pin and / or preferably double-sided adhesive tape. This has proven to be technically advantageous. This allows for reliable and easy installation of the locking device.

[0012] A simpler approach is to make at least one locking device, at least partially, a metal plate, an injection-molded plastic part, and / or a spring wire.

[0013] As mentioned at the beginning of the text, protection is also sought for a configuration comprising: at least one flat drawer element, preferably a drawer back wall and / or drawer bottom; at least one drawer side frame, the at least one drawer side frame including at least one—preferably recessed—fixing area for at least partially fixing the edge of the drawer element; and at least one fixing device according to the invention, by means of which the drawer element is fixed to or can be fixed to the drawer side frame, preferably wherein the drawer element is at least partially made of wood, wood-based materials, wood substitutes, honeycomb panels and / or metal.

[0014] According to a preferred embodiment of this configuration, the at least one locking device is arranged on the drawer side frame, preferably on the horizontal web of the container rail.

[0015] As an alternative or supplement, the at least one mounting base may be arranged above and / or in the drawer side frame, preferably on the horizontal web of the container rail, the rear wall support and / or the inner wall, and / or on the bottom or back of the drawer element.

[0016] To further improve the fixation of the drawer element on the drawer side frame, it can be advantageously designed that the configuration includes at least one additional—preferably square-shaped—locking element, by means of which the drawer element can be fixed to the drawer side frame after engagement, preferably to the container rail.

[0017] In addition, protection is also sought for a drawer comprising at least one drawer according to the invention and a piece of furniture comprising a furniture body and at least one drawer according to the invention.

[0018] Finally, protection is also sought for a method of securing at least one flat drawer element (preferably the drawer back wall and / or drawer bottom plate) to a drawer side frame by means of at least one fixing device according to the invention, the drawer side frame including at least one (preferably recessed) fixing area for at least partially securing the edge of the drawer element, the method comprising the following steps: the at least one drawer element moving along a engagement direction transverse to the drawer side frame, the edge of the drawer element at least partially engaging the at least one fixing area of ​​the drawer side frame, and locking the edge of the drawer element against the engagement direction by means of the at least one fixing device after engagement.

[0019] According to a preferred embodiment of the method, the fixing device includes at least one mounting base, in which at least one locking device is at least partially accommodated during engagement, wherein the mounting base includes at least one space of movement transverse to the engagement direction, and wherein the edge of the drawer element is at least limitedly movable in an adjustment direction transverse to the engagement direction after engagement, and / or the at least one locking device includes at least one mounting device, by which the at least one locking device is mounted on and / or in the flat drawer element before engagement, preferably mounted on the bottom surface, back surface and / or end face facing the drawer side frame of the drawer element in the use position.

[0020] As an alternative or supplement, the at least one locking device may be pre-installed on and / or in the flat drawer element before engagement, and anchored on and / or in the flat drawer element by engagement.

[0021] Other preferred embodiments are defined in the additional appendices. Simple Explanation of the Diagram

[0030] Figures 39-42 show another embodiment of the locking device in a perspective view (Figure 39) and from a top view in three different positions (Figures 40-42). Implementation

[0031] Figure 1 shows furniture 40 with a main body 41 and drawers 39. Figure 2 exemplarily shows one of the drawers 39, which is composed of multiple flat drawer elements 1, 2, 3, 42, specifically, in the form of one or more drawer bottom panels 2, drawer back walls 1, two drawer side frames 3, and a front panel 42, which is shown in a disassembled state in Figure 2. One or more of the drawer elements may be at least partially made of wood, wood-based materials, and / or wood substitutes.

[0032] The thickness of flat drawer components is preferably 8 mm or 16 mm.

[0033] At least two of the flat drawer elements 1, 2, 3, and 42 can also be hinged to each other, for example, by means of membrane hinges. Thus, the drawer bottom plate 2 and the drawer rear wall 1 can be hinged together.

[0034] The drawer side frame 3 includes at least one—preferably recessed—fixing area 4 to at least partially fix the edges 5 of the drawer elements 1 and 2 (see, for example, Figure 6).

[0035] The drawer side frame 3 is preferably a side frame made of a hollow metal profile, which may include an inner wall 37 facing the interior space of the drawer, an outer wall 48 facing outward, and at least one cavity 47 between the two (see also Figure 17).

[0036] At least one recess 43 may be provided on the bottom surface of the drawer bottom plate 2, and the horizontal web 34 of the container guide rail 35 of the drawer side frame 3 may be arranged in the at least one recess. However, it is not necessary to provide such a recess 43 and container guide rail 35.

[0037] Figures 3-10 illustrate a first embodiment of a fixing device for securing at least one flat drawer element 1, 2—preferably a drawer rear wall 1 and / or a drawer bottom plate 2—to a drawer side frame 3, the drawer side frame 3 including at least one—preferably recessed—fixing region 4 for at least partially securing the edge 5 of the drawer element 1, 2.

[0038] The fixing device includes at least one locking device 6, which is designed to: engage the edge 5 of the drawer elements 1 and 2 along the engagement direction 11 that crosses the drawer side frame 3 into the at least one fixing area 4, and lock the edge of the drawer elements 1 and 2 against the engagement direction 11 after engagement.

[0039] Furthermore, the fixing device includes at least one mounting base 12, in which at least one locking device 6 can be at least partially housed when engaged, wherein the mounting base 12 includes at least one space of movement transverse to the engagement direction 11, such that the edge 5 of the drawer elements 1, 2 can move at least to a limited extent in the adjustment direction 16 transverse to the engagement direction 11 after engagement.

[0040] In the first embodiment, the at least one mounting base 12 is arranged on the drawer side frame 3, specifically on the horizontal web 34 of the container guide rail 35.

[0041] Mounting base 12 includes an elongated hole. This elongated hole has a width 65 in the longitudinal direction of the drawer side frame 3, which is greater than the width 64 of a portion of the locking device 6, which can be at least partially accommodated in the mounting base 12 during engagement. Thus, the locking device 6 has a gap in the longitudinal direction of the drawer side frame 3.

[0042] The at least one locking device 6 includes at least one—four in the specific case shown—mounting device 17 by means of which the at least one locking device can be mounted on and / or in the flat drawer elements 1, 2, preferably—as shown in the case shown—mounted on the bottom surface 21 of the drawer element 2 in the use position.

[0043] The mounting device 17 includes at least one pointed mounting tab 32 that can be at least partially recessed into the material of the drawer element 2.

[0044] The at least one locking device 6 includes at least one—preferably resilient—locking element 24, wherein the locking element 24—as shown—includes at least one bevel 28, which is displaceable when the edge 5 of the drawer element 2 is engaged with the at least one fixed area 4 along the engagement direction 11 that is transverse to the drawer side frame 3.

[0045] The locking device 6 is at least partially made of a metal plate.

[0046] The locking device 6 may include, for example, a flat base 46 oriented in a plane parallel to the drawer elements 1 and 2, and the at least one mounting device 17 and / or the at least one locking element 24 arranged on the base 46.

[0047] To secure drawer elements 1 and / or 2, one or more locking devices 6 are installed on the edges 5 of drawer elements 1 and / or 2, specifically by means of mounting devices 17, depending on the rated length, characteristics, and / or required fixing force of the drawer elements. For the drawer bottom plate 2, the device is installed on the bottom surface 21, and for the drawer rear wall 22, the device is installed on the back surface 22 (see Figures 9 and 10).

[0048] Then, the edges 5 of drawer elements 1 and / or 2 are inserted into the fixing area 4 of the drawer side frame 3 along the engagement direction 11. The locking device 6 contacts the horizontal web 34 of the container guide rail 35 on the inclined surface 28, first compressing, and then popping out again when the locking element 24 reaches and engages with the mounting base 12. The locking element 24 engages with the edge 66 of the mounting base 12, thereby locking the locking device 6, and subsequently locking the drawer elements 1 and / or 2 in the reverse engagement direction 11 after engagement.

[0049] Since the mounting base 12 includes a space for movement, the locking device 6 can move within a limited range along the adjustment direction 16, which is transverse to the engagement direction 11, without any problems after engagement, for example, to correct any unexpected deviations from the target position of the drawer element 1.

[0050] The fixing device allows drawer elements 1 and / or 2 to be installed on the drawer side frame 3 without the use of tools.

[0051] Disassembly can be achieved manually or by using a disassembly tool 52, such as a screwdriver, to press the locking element 24.

[0052] As shown in Figures 9 and 10, the drawer rear wall 1 can be installed and removed in the same manner as the drawer bottom 2. A hole 45 may be provided, for example, in the rear wall bracket 36 to accommodate the locking element 24 of the locking device 6.

[0053] In the illustrated configuration, the drawer bottom panel 2 and the drawer rear wall 1 are connected to each other via a hinge connection 44. In this case, drawer components 1 and 2 will be assembled together. However, this joint installation is not mandatory. Drawer components 1 and 2 can also be moved and installed independently of each other.

[0054] Figures 11-17 illustrate a second embodiment of the fixing device for fixing at least one flat drawer element 1, 2—preferably a drawer rear wall 1 and / or a drawer bottom plate 2—to a drawer side frame 3, the drawer side frame 3 including at least one—preferably a groove-shaped—fixing area 4 for at least partially fixing the edge 5 of the drawer element 1, 2.

[0055] The fixing device includes at least one locking device 7, which is designed to engage the edges 5 of the drawer elements 1 and 2 along the engagement direction 11 that crosses the drawer side frame 3 into the at least one fixing area 4, and to lock the edges of the drawer elements 1 and 2 against the engagement direction 11 after engagement.

[0056] The fixing device includes at least one mounting base 13, in which at least one locking device 7 can be at least partially housed when engaged. The mounting base 13 includes at least one space of movement transverse to the engagement direction 11, such that the edges 5 of the drawer elements 1 and 2 can move at least to a limited extent in an adjustment direction 16 transverse to the engagement direction 11 after engagement. In the illustrated case, the mounting base 13 includes a narrow slit.

[0057] The at least one locking device 7 includes at least one mounting device 18, by means of which the at least one locking device 7 can be mounted on and / or in the flat drawer elements 1, 2, preferably—as shown in the case—mounted in the use position on the end face 23 of the drawer element 1, 2 facing the drawer side frame 3. The mounting device 18 includes at least one pointed mounting tongue 32 having a barbed profile 31. The tongue 32 with the barbed profile 31 is pressed into the drawer rear wall 1 or drawer bottom plate 2 from the front.

[0058] The at least one locking device 7 includes at least one—preferably resilient—locking element 25, wherein the locking element 25 includes at least one bevel 28, the at least one bevel 28 being displaceable when the edge 5 of the drawer elements 1, 2 is engaged with the at least one fixed area 4 along the engagement direction 11 that is transverse to the drawer side frame 3.

[0059] The at least one locking device 7 includes at least one elastic element 29—preferably facing the drawer side frame 3—which, after engagement, applies a force to the at least one locking device 7 in the opposite engagement direction 11.

[0060] The at least one locking device 7 is made of at least part of a metal plate.

[0061] To secure drawer elements 1 and / or 2, one or more—in this particular case, three—locking devices 7 are mounted on drawer elements 1 and / or 2 by means of mounting device 28. The edges 5 of drawer elements 1 and / or 2 are then engaged along engagement direction 11 into the fixing area 4 of drawer side frame 3. The locking element 25 contacts the boundary contour of mounting base 13, resulting in elastic compression, and subsequently ejects once the outer contour is crossed and drawer elements 1 and / or 2 are in the desired fixed position. The bevel 28 facilitates the elastic compression of the locking element 25. The elastic element 29, upon engagement, impacts the inner wall 37 of drawer side frame 3, in which mounting base 13 is located, and—depending on tolerances—undergoes varying degrees of compression to minimize gaps on the plane of drawer elements 1 and / or 2.

[0062] Figures 18-21 illustrate a third embodiment of the fixing device for fixing at least one flat drawer element 1, 2—preferably a drawer rear wall 1 and / or a drawer bottom plate 2—to a drawer side frame 3, the drawer side frame 3 including at least one—preferably a groove-shaped—fixing area 4 for at least partially fixing the edge 5 of the drawer element 1, 2.

[0063] The fixing device includes at least one locking device 8, which is designed to engage the edges 5 of the drawer elements 1 and 2 along the engagement direction 11 that crosses the drawer side frame 3 into the at least one fixing area 4, and to lock the edges of the drawer elements 1 and 2 against the engagement direction 11 after engagement.

[0064] Similar to the second embodiment, the fixing device includes at least one mounting base arranged on the inner wall 37 of the drawer side frame 3. The at least one locking device 8 can be at least partially housed in the at least one mounting base when engaged. The mounting base includes at least one space of movement transverse to the engagement direction 11, such that the edge 5 of the drawer elements 1 and 2 can move at least to a limited extent in the adjustment direction 16 transverse to the engagement direction 11 after engagement.

[0065] The at least one locking device 8 includes at least one—four in the specific case shown—mounting device 19, by means of which the at least one locking device 8 can be mounted—pressed into—the flat drawer elements 1, 2 and / or in the middle, preferably mounted on the bottom surface 21 or back surface 22 of the drawer elements 1, 2 in the use position. Each of the at least one mounting device 19 includes at least one pointed mounting tab 32 with a barbed profile 31.

[0066] The at least one locking device 8 includes at least one—preferably resilient—locking element 25, wherein the locking element 25 includes at least one bevel 28, which is displaceable when the edge 5 of the drawer elements 1, 2 is engaged with the at least one fixed area 4 along the engagement direction 11 that is transverse to the drawer side frame 3.

[0067] The at least one locking device 8 includes at least one—in the case of two—elastic element 30 facing the drawer side frame 3, which, after engagement, applies a force to the at least one locking device 8 in the opposite engagement direction 11 and minimizes any gaps that may be caused by tolerance.

[0068] The at least one locking device 8 is made of at least part of a metal plate.

[0069] As shown in Figure 21, the horizontal web 34 of the container guide 35 may include a recess 50 for accommodating the base 46 of the locking device 8. Thus, the bottom surface 21 of the drawer bottom plate 2 can be flush with the horizontal web 34. The recess 50 may be formed, for example, by stamping during the manufacturing of the container guide 35.

[0070] As an alternative or supplement, a notch 51 may be provided in the horizontal web 34. This notch 51 can be used to accommodate the bend 49 between the base 46 and the vertical web 67. On the other hand, the notch 51 can serve as an entry point for the disassembly tool 52, through which the locking element 25 can be disassembled. An additional notch for the disassembly tool 52, adjacent to this notch, may be arranged in the drawer side frame 3.

[0071] In this embodiment, in order to disassemble the flat drawer element 1 or 2, a suitable disassembly tool 52, such as a screwdriver, can be used to operate the locking element 25 so that it can be removed from or by means of the mounting base. Other embodiments are similar.

[0072] Figures 22-27 illustrate a fourth embodiment of the fixing device for fixing at least one flat drawer element 1, 2, preferably a drawer back wall 1 and / or a drawer bottom plate 2, to a drawer side frame 3. The drawer side frame 3 includes at least one fixing area 4, preferably a groove, for at least partially fixing the edge 5 of the drawer element 1, 2. The fixing device includes at least one locking device 9, which is designed to engage the edge 5 of the drawer element 1, 2 in the engagement direction 11 intersecting the drawer side frame 3 with the at least one fixing area 4, and to lock the edge of the drawer element 1, 2 against the engagement direction 11 after engagement.

[0073] The fixing device includes at least one mounting base 14, in which at least one locking device 9 can be at least partially housed when engaged. The mounting base 14 includes at least one space of movement transverse to the engagement direction 11, such that the edges 5 of the drawer elements 1 and 2 can move at least limitedly in an adjustment direction 16 transverse to the engagement direction 11 after engagement. The at least one mounting base 14 is designed as an elongated hole. The at least one mounting base 14 is arranged on and / or within the drawer side frame 3, preferably on the inner wall 37.

[0074] The at least one locking device 9 includes at least one mounting device 20, by means of which the at least one locking device 9 can be mounted on and / or in the flat drawer elements 1, 2, preferably mounted on the end face 23 of the drawer elements 1, 2 facing the drawer side frame 3 in the use position. The at least one mounting device 20 has a barb profile 31 and is designed as a pin 33.

[0075] The at least one locking device 9 includes at least one—preferably resilient—locking element 26, wherein the locking element 26 includes at least one bevel 28, which is displaceable when the edge 5 of the drawer elements 1, 2 engages the at least one fixed region 4 along the engagement direction 11 intersecting the drawer side frame 3. As specifically illustrated, two spaced-apart locking elements 26 may be provided, each of which is rotatable about a hypothetical pivot axis 54, which is oriented transversely to the longitudinal direction of the drawer side frame 3. During engagement, the locking elements 26 may pivot in opposite directions. This is shown in Figures 26 and 27.

[0076] The at least one locking device 9 is at least partially made of injection-molded plastic, wherein the mounting device 20 is preferably connected to the base 46 via at least one pre-interruption point, which is released during installation. For example, the at least one pre-interruption point may be designed as a fixing rib 53 and / or more than one—for example, four—pre-interruption points may be provided. That is, the mounting device 20 can be injection-molded onto the base 46.

[0077] For installation, at least one locking device 9 can be arranged on the front of the flat drawer elements 1 and 2. Then, the pin 33 can be pressed into the material of the flat drawer elements 1 and 2. Subsequently, the drawer side frame 3 is pressed onto the flat drawer elements 1 and 2, wherein the locking element 26 is first elastically compressed during movement through the mounting base 14 and then springs back open once the drawer side frame 3 is in the desired position.

[0078] In this embodiment, and similarly in other embodiments, a mounting device 55 may be optionally provided for mounting the drawer rear wall 1.

[0079] For disassembly, it can be designed such that: the drawer side frame 3 is disengaged or detached from the drawer rear wall 1, while the locking element 26 springs back and springs back open once the mounting base 14 is pulled above the drawer side frame 3.
