Fastening device for detachably fastening a front panel to a drawer

Description

[0001] The invention relates to a fastening device with the features of the preamble of claim 1. The invention further relates to an arrangement comprising a drawer, a front panel, and at least one such fastening device, as well as a piece of furniture with at least one such arrangement. Finally, the invention relates to a method for fastening a front panel to a drawer.

[0002] Fastening devices according to the preamble of claim 1 are known from the prior art. A disadvantage of existing fastening devices is that they are stiff, since frictional forces must be overcome when the individual components move relative to each other. This particularly hinders the insertion of the at least one furniture fitting and reduces the service life of the fastening devices.

[0003] Patent application DE 20 2014 002229 U1 discloses a fastening device in which a furniture fitting can be engaged by a catch device. The movement of the catch device is coupled to the movement of a cam plate. The cam plate is pushed upwards by a spring, so that a furniture fitting engaged in the catch device is pulled towards the fastening device.

[0004] Another fastening device is known from DE 10 2014 011090 A1.

[0005] The object of the present invention is to overcome the disadvantages of the prior art and to provide a fastening device that is improved compared to the prior art and is characterized in particular by low frictional forces. A further object is to provide an arrangement with such an improved fastening device and a piece of furniture with at least one such arrangement. Finally, a further object is to provide a method for fastening a front panel to a drawer using a fastening device improved according to the invention.

[0006] These problems are solved by the features of independent claims 1, 11, 12 and 13.

[0007] With regard to the fastening device, it is therefore provided that the coupling device has at least one actuating element and at least one actuating contour in or on which the at least one actuating element is arranged or can be arranged, wherein the at least one actuating element is arranged on the at least one catch device and the at least one actuating contour is arranged on the at least one locking device, or vice versa, and wherein the at least one actuating contour is designed such that the movement of the at least one locking device when inserting the at least one furniture fitting is only temporarily coupled with the movement of the at least one catch device.

[0008] By only temporarily coupling the movement of the at least one locking device with the movement of the at least one catch device during the insertion of the at least one furniture fitting, it is possible to move the at least one locking device only when actually necessary. In the prior art, the movement of the at least one catch device and the movement of the at least one locking device are permanently coupled, so that situations can arise in the process where one of these two devices is moved without serving any specific purpose. This results in unnecessary friction losses. In contrast, in the present invention, the two devices can be moved as needed.For example, it is possible to implement a process sequence in which the at least one furniture fitting is picked up by the at least one catch device and automatically pulled towards the drawer, wherein the movement of the at least one catch device and the movement of the at least one locking device are initially decoupled, and then coupled to each other via the coupling device, so that initially only the at least one catch device moves, whereas the at least one locking device remains essentially at rest, and then the at least one locking device is moved in order to position it on the at least one furniture fitting and thus prevent an unintentional release of the at least one furniture fitting from the fastening device.

[0009] A simple way to ensure that the at least one catch device automatically pulls the at least one furniture fitting towards the drawer when it is inserted, according to a preferred embodiment, is that the fastening device includes at least one spring, and that the at least one catch device automatically pulls the at least one furniture fitting towards the drawer by the force of the at least one spring when it is inserted. Alternatively, other drive mechanisms can also be provided.

[0010] Furthermore, it is advantageous that the at least one catching device is movable into a ready position in which the at least one catching device is ready to receive the at least one furniture fitting upon insertion, and into at least one drive position in which the at least one catching device automatically pulls the at least one furniture fitting towards the drawer after it has been received, preferably wherein the at least one catching device has a catching lever that can be pivoted about a pivot axis.

[0011] With regard to the at least one locking device, it has proven particularly advantageous that the at least one locking device comprises, preferably a curved, locking contour which can be arranged on the at least one furniture fitting to prevent the unintentional release of the at least one furniture fitting from the fastening device, preferably wherein the at least one furniture fitting can be clamped by the locking contour, and / or the at least one locking device can be moved into a release position in which the at least one furniture fitting is freely movable relative to the at least one locking device, and into a locking position in which unintentional release of the at least one furniture fitting from the fastening device is prevented, preferably wherein the at least one locking device has a locking lever that can be pivoted about a pivot axis.

[0012] With regard to the at least one actuating element, a particularly stable embodiment can be achieved by designing the at least one actuating element as a bolt, preferably with a widened head. The at least one actuating element is rigidly connected to the at least one catch device or the at least one locking device on which it is arranged.

[0013] To couple the movement of the at least one locking device with the movement of the at least one catching device when inserting the at least one furniture fitting, it is provided according to the invention that the at least one positioning contour has at least one coupling section.

[0014] To decouple the movement of the at least one locking device from the movement of the at least one catch device when inserting the at least one furniture fitting, the invention further provides that the at least one positioning contour has at least one decoupling section separate from the coupling section, wherein the at least one coupling section and the at least one decoupling section are angled relative to each other, or the at least one positioning contour has an open end adjacent to the at least one coupling section. In the case that the at least one decoupling section and the at least one coupling section are angled relative to each other, it has been found that the at least one decoupling section and the at least one coupling section form an angle of approximately 90° relative to each other.

[0015] To specify the movement of the at least one actuating element, the fastening device can have at least one mounting plate in which at least one guide contour is formed, and the at least one actuating element is slidably mounted in or on the at least one guide contour.

[0016] It has also proven advantageous that the at least one furniture fitting has at least one fastening element for mounting the at least one furniture fitting on the front panel, and / or a transverse bolt or a pin which interacts with the at least one catch device and / or the at least one locking device.

[0017] It has also proven advantageous that at least one of the furniture fittings is asymmetrically designed with respect to an imaginary center plane. This makes it possible to optimally support the front panel while simultaneously achieving a compact design for the mounting device. Furthermore, this measure allows the at least one furniture fitting to be used universally for different front panel heights.

[0018] Further preferred embodiments consist in the fastening device having a release device for the at least one locking device, which enables the at least one furniture fitting to be intentionally released from the fastening device, wherein the release device lifts the at least one locking device from the at least one furniture fitting and releases the at least one furniture fitting, preferably wherein the release device has an externally accessible tool receptacle for a tool by means of which the release device can be actuated, and / or has a height adjustment device and / or a side adjustment device for the front panel.

[0019] As stated at the outset, protection is also sought, on the one hand, for an arrangement consisting of a drawer, a front panel and at least one fastening device according to the invention for detachably fastening the front panel to the drawer, preferably wherein the drawer comprises at least one drawer side wall that is at least partially hollow and the at least one fastening device is arranged predominantly in the at least one drawer side wall, and on the other hand, for a piece of furniture with at least one such arrangement.

[0020] According to the inventive method for attaching a front panel to a drawer, in particular to a drawer side wall, by means of at least one fastening device according to the invention, it is provided that in a first method step at least one furniture fitting is mounted on the front panel, in a second method step the at least one furniture fitting is picked up by the at least one catch device and automatically pulled towards the drawer, wherein the movement of the at least one catch device and the movement of the at least one locking device are initially decoupled, and then coupled to each other via the coupling device, and in a third method step an unintentional release of the at least one furniture fitting from the fastening device is prevented by means of the at least one locking device.

[0022] In Figur 1 A drawer side panel 7 is shown, which includes a decorative profile 54 that is at least partially U-shaped and a drawer slide 55, with the decorative profile 54 being mounted on the drawer slide 55. The drawer slide 55 has a support rib 74 on which a drawer base 73, indicated by dashed lines, can be placed.

[0023] A front panel 5 is indicated by a dashed line, to which a furniture fitting 8 is mounted. This furniture fitting 8 is part of a fastening device 1 (compare the following figures) for detachably attaching the front panel 5 to the drawer 6. The furniture fitting 8 has two fastening elements 47 in the form of expansion dowels.

[0024] At the opposite end of the drawer side wall 7, a back panel holder 53 is arranged for holding a drawer back panel.

[0025] In the Figur 2a The front area of ​​the drawer side wall 7, facing the front panel 5, can be seen in an enlarged view, with the decorative profile 54 omitted.

[0026] As can be seen, a large part of the fastening device 1 is arranged on the drawer rail 55. How to attach this and the two following ones. Figuren 2b und 2c The fastening device 1 comprises, in addition to the furniture fitting 8 which can be pre-mounted on the front panel 5, a catch device 10 assigned to the drawer 6, which receives the furniture fitting when inserted and automatically pulls it towards the drawer 6, a locking device 13 separate from the catch device 10, which prevents the furniture fitting 8 from unintentionally releasing from the fastening device 1, and a coupling device 17, 18 for coupling the movement of the locking device 13 with the movement of the catch device 10.

[0027] The coupling device 17, 18 comprises an actuating element 17 and an actuating contour 18 in which the actuating element 17 is arranged, wherein the actuating element 17 is arranged on the catch device 10 and the actuating contour 18 on the locking device 13. An equally possible arrangement of the actuating element 17 and the actuating contour 18 on the locking device 13 and the catch device 10 would also be permissible.

[0028] The actuating element 17 is designed as a bolt, wherein the bolt in the illustrated embodiment has a widened head.

[0029] The positioning contour 18 is designed such that the movement of the locking device 13 during the insertion of the furniture fitting 8 is only temporarily coupled to the movement of the catch device 10. For this purpose, the positioning contour 18 has a coupling section 34 via which the movement of the locking device 13 during the insertion of the furniture fitting 8 can be coupled to the movement of the catch device 10 (compare the enlarged section of the locking device 13 in Figur 2c Furthermore, the positioning contour 18 has a decoupling section 37, separate from the coupling section 34, for decoupling the movement of the locking device 13 from the movement of the catch device 10 when the furniture fitting 8 is inserted. In the illustrated embodiment, the coupling section 34 and the decoupling section 37 are angled relative to each other. They form an angle 58 of approximately 90°.

[0030] The fastening device 1 includes a spring 21. When the furniture fitting 8 is inserted, the catch device 10 automatically pulls the furniture fitting 8 towards the drawer 6 by the force of the spring 21. In the illustrated embodiment, the spring 21 is designed as a compression spring. The spring 21 is further arranged on a spring guide 56 and is supported against a support contour 79 of a mounting plate 40 of the fastening device 1.

[0031] The mounting plate 40 also has a guide contour 44 in which the actuating element 17 is slidably mounted.

[0032] In addition to the mounting plate 40, there is also a cover plate 61. This has been omitted in most of the following figures to allow a view of the locking device 13 located between the mounting plate 40 and the cover plate 61.

[0033] The catch device 10 has a rotation about an axis 22 (compare Figur 2a ) pivotable catch lever 23. In the illustrated embodiment, this is directly acted upon by the spring 21.

[0034] The locking device 13 has a locking lever 31 that can be pivoted about a pivot axis 30.

[0035] In addition, the locking device 13 includes a locking contour 26, which can be arranged on the furniture fitting 8, to prevent the furniture fitting 8 from unintentionally detaching from the fastening device 1. In the present embodiment, the locking contour 26 is curved. As can be seen, for example, from the Figuren 6a und 6b The furniture fitting 8 can be clamped by the locking contour 26.

[0036] How to particularly the Figur 2c As can be seen from the figures, the furniture fitting 8 comprises a U-profile 57 in which a transverse bolt 48 is arranged. In the present embodiment, the furniture fitting 8 interacts with the catch device 10 and the locking device 13 via this transverse bolt 48. In the following figures, only this transverse bolt 48 of the furniture fitting 8 is shown.

[0037] The transverse bolt 48 interacts with a guide contour 60 formed in the mounting plate 40. At the end facing the front panel 5, the guide contour 60 has a hook-in contour 59, which facilitates the positioning of the front panel 5 or the furniture fitting 8 attached to it in relation to the other components of the fastening device 1. This is particularly advantageous for very heavy front panels 5.

[0038] Furthermore, the furniture fitting 8 is in relation to an imaginary middle plane 49 (compare Figur 2c ) asymmetrically formed.

[0039] The fastening device 1 further comprises a release device 50 for the locking device 13, wherein the release device 50 enables the furniture fitting 8 to be intentionally released from the fastening device 1, and wherein the release device 50 lifts the locking device 13 from the furniture fitting 8 and releases the furniture fitting 8. In the present embodiment, the release device 50 has an externally accessible tool receptacle for a tool, for example a screwdriver, by means of which the release device 50 can be actuated.

[0040] In addition, the fastening device 1 includes a height adjustment device 51, with which the height of the front panel 5 relative to the drawer side wall 7 or to the drawer 6 can be adjusted. In the illustrated embodiment, the height adjustment device 51 includes an eccentric screw with a rounded triangular contour 75, which bears against a support contour 76 formed on the mounting plate 40.

[0041] Finally, the fastening device 1 also includes a lateral adjustment device 52 to adjust the lateral position of the front panel 5 relative to the drawer side wall 7 or to the drawer 6. In the illustrated embodiment, the lateral adjustment device 52 comprises a screw with a thread which is supported in an opening 77 in the mounting plate 40.

[0042] The functioning of the fastening device 1 according to the first embodiment will now be explained with reference to the Figuren 3a bis 6b described, whereby in these figures the components recognizable in a top view from the side are shown with solid lines and the components arranged on the opposite side are shown with dashed lines, so that the interaction of all components can be better understood: The Figuren 3a und 3b Figure 1 shows the fastening device 1 according to the first embodiment immediately before the furniture fitting 8 or the cross bolt 48 is inserted. The catch device 10 is in a ready position, in which it is prepared to receive the furniture fitting 8. At the same time, the locking device 13 is in a release position, in which the furniture fitting 8 is freely movable relative to the locking device 13.

[0043] The catch lever 23 is located in an over-center position relative to the axis of rotation 22 and the support point 79 on the mounting plate 40. The actuating element 17 holds the locking lever 31 in the released position via the actuating contour 18.

[0044] The transverse bolt 48 of the furniture fitting 8 is arranged at the level of the hanging contour 59 of the guide contour 60.

[0045] Based on the Figuren 3a und 3b When a user moves the front panel 5, and thus the furniture fitting 8 or the cross bolt 48, towards the drawer 6, the catch 10 engages the furniture fitting 8 or the cross bolt 48. The catch lever 23 is moved from its over-center position past the dead center, releasing the force stored in the compression spring 21 and allowing the catch lever 23 to move further automatically. This moves the furniture fitting 8 or the cross bolt 48 further inwards along the guide contour 60. In other words, the catch 10 automatically pulls the furniture fitting 8 towards the drawer 6. The catch 10 passes through a series of drive positions during this process.

[0046] If you compare the Figuren 3a und 3b With reference to 4a and 4b, it can be observed that the position of the locking lever 31 has not changed. This is because the actuating element 17 has moved along the actuating contour 18 in a decoupling section 37. For this purpose, the decoupling section 37 is essentially circular on an imaginary circle around the axis of rotation 22. The actuating contour 18 is thus designed such that the movement of the locking device 13 when the furniture fitting 8 is inserted is initially decoupled from the movement of the catch device 10. Therefore, no forces need to be applied to move the locking lever 31.

[0047] Based on the position according to the Figuren 4a und 4b The actuating body 17 now moves into a coupling section 34 of the actuating contour 18 (compare Figur 5a und 5b ), i.e., that the movement of the locking device 13 is now coupled with the movement of the catch device 10.

[0048] The cross bolt 48 or the furniture fitting 8 is pulled further towards the drawer 6 by the catch lever 23 of the catch device 10. At the same time, the locking lever 31 begins to pivot downwards behind the cross bolt 48 around the pivot point 30 and close the guide contour 60.

[0049] These processes continue until the front panel 5 comes to rest against the drawer side wall 7, which occurs in the position of the fastening device 1 according to the Figuren 6a und 6b This is the case. In this position, the locking lever 31 clamps the transverse bolt 48 via a curved locking contour 26. This prevents the furniture fitting 8 from unintentionally releasing from the fastening device 1. The locking device 13 assumes a locked position.

[0050] If it is intended to release the furniture fitting 8 from the fastening device 1, the release device 50 can be used for this purpose. In the illustrated embodiment, this device is designed as a tool receptacle for a tool on the catch lever 23. By inserting the tip of a suitably designed screwdriver, the catch lever 23 can be moved back to its original ready position. Simultaneously, the locking device 13 is moved from the locked position to the unlocked position via the coupling device 17, 18. Here, too, the movement of the catch device is only temporarily coupled to the movement of the locking device.

[0051] The Figuren 7a bis 9b Figure 1 shows a second embodiment of a fastening device 2 for detachably attaching a front panel 5 to a drawer 6. This embodiment is particularly suitable for tall front panels 5. For this purpose, two furniture fittings 8 and 9 arranged one above the other are provided, which can be pre-mounted on the front panel 5.

[0052] The lower part of the fastening device 2, which interacts with the furniture fitting 8, is essentially identical to the first embodiment described above. In addition, a further locking device 14 is provided for the furniture fitting 9, the movement of which is coupled to the movement of the catch device 10 or the locking device 13 for the lower furniture fitting 8.

[0053] The spring guide 56 is used for the movement coupling. Specifically, the spring guide 56 includes a guide track 70 in which a pivot point 69 of an intermediate lever 46 is slidably mounted. The intermediate lever 46 is pivotally mounted about a pivot point 65 on the mounting plate 41 of the fastening device 2. The locking device 14 is linearly displaceable relative to the mounting plate 41. The intermediate lever 64 interacts with the locking device 14 on the one hand via the pivot point 65, which is designed as a bolt, and on the other hand via another bolt 67 arranged on the intermediate lever 64. The bolts 65 and 67 engage in guide tracks 68 and 66, which are formed in the locking device 14.

[0054] The locking device 14 has a locking contour 27 for the furniture fitting 9, which in this case is linear.

[0055] The intermediate lever 64 is actuated by a tension spring 63 in addition to the spring 21.

[0056] Reference should also be made to a cover plate 62, which is arranged on the mounting plate 41.

[0057] In contrast to furniture fitting 8, furniture fitting 9 has only one fastening element 47. Furthermore, furniture fitting 9 does not interact with fastening device 2 via a cross bolt 48, but rather via a pin 78.

[0058] As can be seen in particular from a comparison of the Figuren 8a und 8b As shown in Figures 9a and 9b, when the catch lever 23 of the catch device 10 is moved, the locking device 14 is pushed upwards via the spring guide 56, which acts as a transmission lever, the springs 21 and 63, the intermediate lever 64, and the bolts 65 and 67 mounted in the guide tracks 66 and 68. This action locks the furniture fitting 9 or the pin 78 by the locking contour 27, thus preventing the furniture fitting 9 from unintentionally releasing from the fastening device 2.

[0059] The locking device 14 can be moved back to its original release position together with the locking device 13 via the unlocking device 50 and the coupling mechanism 56, 64, 66, 68, 65, 67, 63 and 21 arranged between the catch device 10 and the locking device 14.

[0060] The Figuren 10a bis 13b Figure 3 shows a third embodiment of the fastening device 3. The function of this fastening device 3 essentially corresponds to the function of the fastening device 1 according to the first embodiment.

[0061] A key difference lies in the design of the coupling device 17, 19 for coupling the movement of the locking device 15 or the locking lever 32 with the movement of the catch device 11 or the catch lever 24. Specifically, in this case, the actuating contour 19 has an open end 39 adjacent to the coupling section 35. When the actuating element 17 is located outside the actuating contour 19, the movements are decoupled from each other (compare Figuren 10a bis 11b If the actuator 17 enters the coupling section 35 at the open end 39 and the actuator 17 moves along the coupling section 35, the movements are coupled together.

[0062] In this case, the locking of the transverse bolt 48 is also effected by a curved locking contour 28 formed on the locking lever 32.

[0063] In this embodiment as well, the actuating element 17 moves along a guide contour 45, which is formed in a mounting plate 42.

[0064] The Figuren 14a bis 19b Figure 4 shows a fourth embodiment of the fastening device 4. The function of this fastening device 4 essentially corresponds to the function of the fastening devices 1 and 3 according to the first and third embodiments.

[0065] A special feature of this embodiment is that, in addition to a guide contour 46 in a mounting plate 43 for guiding the carrier body 17, a catch lever positioning contour 71 is also provided for guiding a driver 72 arranged on the catch lever 25 of the catch device 12.

[0066] In this embodiment, the movement of the locking lever 33 of the locking device 16 and the movement of the catch lever 25 of the catch device 12 are coupled not only via the actuating element 17 and the actuating contour 20, which comprises a coupling section 36 and a decoupling section 38, but also, when the furniture fitting is intended to be released from the fastening device 4 by means of the release device 50, via the driver 72, which, when the catch lever 25 moves from the locking position to the ready position, comes into contact with an outer contour 80 of the catch lever 25, thereby moving the locking lever 33 as well.

[0067] The Figuren 20a bis 22bFigure 1 shows a fifth embodiment of a fastening device 81 according to the invention. This embodiment is very similar to the second embodiment. It differs in the design of the upper part for fastening the furniture fitting 9. When the furniture fitting 8 is inserted, the catch lever 23 of the catch device 10 is pivoted from its over-center position about the axis of rotation 22 under the influence of the spring 21. The spring guide 56 is also pivoted about the support point 92. A guide track 70 is arranged at the end of the spring guide 56, in which a pivot point 69 of an intermediate lever 87 is movably mounted. The pivoting of the spring guide 56 tilts the intermediate lever 87 about the pivot point 88.This causes a locking lever 85 of a locking device 82 to pivot about a pivot axis 84 via a bolt 90, which is mounted in a guide track 89, so that the locking lever 85, with a curved locking contour 83, comes to rest against the pin 78 of the furniture fitting 9. The bolt 90 is located on the locking lever 85 and the guide track 89 on the intermediate lever 87. The bolt 90 is simultaneously guided by a guide track 91, which is formed in the mounting plate 86.

[0068] When the locking lever 85 moves from the release position to the locking position, the tension spring 63 is tensioned. The force stored in the tension spring 63 assists the reverse movement of the locking lever 85 from the locking position to the release position when the furniture fittings 8 and 9 are intentionally released from the fastening device 81 by means of the release device 50.
