Shelf fittings and associated furniture arrangement

Description

[0001] The invention relates to a fitting, in particular a shelf fitting, for connecting two parts, in particular two furniture parts such as e.g.of a shelf on a side wall, comprising a first fitting part with a first mounting body for mounting on a first part to be joined and with a slide slidably guided in the first mounting body, which is slidable from a front starting position, in which at least one front slide end having an undercut projects forward from the first mounting body, against the action of a restoring force backward to a rear end position, in which the front slide end does not project from the first mounting body, and a second fitting part in the form of a second mounting body for mounting on a second part to be joined, wherein the second mounting body has a keyhole with an insertion opening for inserting the front slide end and with a slot opening adjoining the insertion opening, which is narrower than the insertion opening, for engaging behind the undercut of the front slide end.The invention also relates to an associated arrangement comprising two parts which are connected to each other by means of the fitting.

[0002] Such fittings are well known.

[0003] A two-part shelf fitting is known from WO 2015 / 158622 A1. In a fitting housing of a first fitting part, a slide can be moved from a forward position to a rear position against the action of a spring by means of an eccentric. The eccentric is rotatably mounted in the fitting housing and interacts with a shoulder of the slide to move the slide to the rear position. The front end of the slide of the first fitting part engages a keyhole of a second fitting part, thereby securing the two fitting parts to each other.

[0004] A similar two-part shelf fitting is also known from EP 3 281 555 A1. In a fitting housing of a first fitting part, a slider can be moved from a front position to a rear position against the action of a spring. The first fitting part engages a keyhole of a second fitting part with a front slider head, thereby securing the two fitting parts to one another. The second fitting part has an inclined surface along which the slider head can be moved out of the keyhole by means of a lateral displacement.

[0005] WO 2021 / 019455 A1 also discloses a shelf fitting with a fitting housing in which a slide can be moved from a front position to a rear position against the action of a spring by means of a rack and pinion. For this purpose, the rack formed on the slide meshes with the pinion rotatably mounted in the fitting housing.

[0006] In contrast, the present invention aims to provide a fitting for connecting two parts that is as simple as possible.

[0007] This problem is solved according to the invention by a fitting having the features of claim 1.

[0008] According to the invention, the slider has at least two parallel front slider ends, each having an undercut, which interact with corresponding keyholes of the second fitting part.

[0009] Preferably, the at least two front slider ends are designed in a pin shape.

[0010] The fitting according to the invention enables tool-free assembly on the two parts, with the mounted fitting being virtually invisible. In the first embodiment of the invention, the slide can be pushed from the outside against the action of the restoring force into the rear end position via a gear and rack. In the second embodiment of the invention, the slide can be pushed against the action of the restoring force into the rear end position via the sloping opening base.

[0011] The restoring force is preferably provided by a spring, in particular a compression spring, which is supported both on the first mounting body and on the slide.

[0012] The sliding mechanism is particularly advantageous when locked into the first mounting element in its rear end position. This allows all fittings to be moved to their rear end position before the shelf can be removed during disassembly of a shelf with multiple such fittings.

[0013] Preferably, in the first embodiment of the invention, the first mounting body has an access opening for rotating the gear. In the second embodiment, the depth of the inclined opening base at the insertion opening corresponds at least to the sum of the distance from the end face to the undercut of the front slide end and the thickness of the opening wall of the second mounting body that defines the slot opening.

[0014] The second fitting part can advantageously have a diagonally backward-running pull contour along the slot opening for the undercut of the front slide end in order to draw the first and second fitting parts into mutual contact.

[0015] Particularly preferably, the first mounting body is formed from two housing halves, preferably of identical construction, each having an internal guide recess for the slide. At least one of the two housing halves, and in particular both housing halves, can each have a bearing opening in which the gear is rotatably mounted and accessible from the outside for rotary actuation.

[0016] Preferably, the first mounting body and the second mounting body have external projections and / or external transverse ribs to anchor the mounting bodies in corresponding bores of furniture parts.

[0017] The invention also relates to an arrangement, in particular a furniture arrangement, comprising two parts and a fitting designed as described above, wherein the first fitting part is mounted on the first part and the second fitting part on the second part, and wherein the at least two front sliding ends are inserted into the corresponding keyholes and their undercuts engage behind the slot openings in the insertion direction. Only a bore in the shelf is visible for resetting the sliding element, after it has initially been moved out of the keyhole undercut, back to its rear end position and thus for releasing the connection.

[0018] Preferably, the first fitting component with its first mounting body is mounted in a recess, in particular a slotted hole or milling, of the first part, and the second fitting component with its second mounting body is mounted in a recess, in particular a slotted hole or milling, of the second part. The front faces of the two mounting bodies advantageously align flush with the two parts and abut each other.

[0019] Further advantages of the invention will become apparent from the description, the claims, and the drawing. Likewise, the aforementioned and further listed features can be used individually or in any combination. The embodiments shown and described are not to be understood as an exhaustive list, but rather serve as examples for illustrating the invention.

[0021] The in Fign. 1a, 1b shown (shelf) fitting 1 It is used to connect two pieces of furniture, in this case a shelf. 2 on a side wall 3 ( Fig. 5 ), and features two fitting parts 10 , 30 on.

[0022] As in Fig. 2 As shown, the first fitting 10 has a first mounting body (shelf housing) 11 , a slider guided in a straight line within it 12 and a compression spring 13 ( Fig. 1b ) which is supported at one end on the first mounting body 11 and at the other end on the slide 12. The slide 12 is made of a Fign. 1a, 1b shown, front starting position, in which two each have an undercut 14 featuring, here pin-shaped, front sliding ends 15protrude forward from the mounting body 11, can be displaced backward against the action of the compression spring 13 to a rear end position in which the front slider ends 15 no longer protrude from the mounting body 11, but are flush with a front 16 of the first mounting body 11. The undercut 14 can be a shoulder of the front slide end 15 and, as shown, can be formed, for example, by an annular groove.

[0023] Slider 12 has a sliding mechanism that changes in its sliding direction. 17 Extending rack 18 , with which a gear rotatably mounted in the first mounting body 11 19 The gear 19 can be manually rotated from the outside to move the slide 12 against the force of the compression spring 13 into the rear end position. The gear 19 can, for example, be mounted in a rectangular opening, as also shown in the exemplary embodiment. 20The slide 12 may be arranged in a manner where one side wall is designed as a rack 18 and the opposite, smooth side wall rests against the gear 19 and can slide on it. Alternatively, the opposite side wall may not rest against the gear 19 and therefore may not slide on it; in this case, the slide 12 may also be arranged in a non-rectangular opening.

[0024] Preferably, the first mounting body 11 consists of two identical housing halves. 21 with inner guide recesses 22 for the intermediate slide 12. The two housing halves 21 each have a bearing or access opening open inwards and outwards. 23 on, in which the gear 19 is rotatably mounted and through which a tool can be inserted from the outside to cut into a slot 24, here a Phillips head screw, or alternatively an internal hexagon or Torx screw of the gear 19. The slider 12 is slidably guided in the guide recesses 22, with two lateral locking lugs. 25 The rear end of the slider prevents the slider 12 from being pushed out of the first mounting body 11 (in this position, the front slider ends 15 are recessed in the first mounting body 11). The in Fig. 1a The top and bottom surfaces of the first mounting body 11 shown can optionally be fitted with pointed, here pyramid-shaped projections. 26 (or transverse ribs) may be structured, and the two narrow sides of the first mounting body 11 may have external transverse ribs. 27 exhibit.

[0025] The second fitting part 30 is a second mounting body (sleeve) 31 with a front 32, which has two keyholes 33 spaced apart in the width direction of the front 32. As in Fig. 3 As shown, these keyholes 33 each have a round insertion opening. 34 for inserting the front slide end 15 and a slot opening which, in the width direction, here on the left, adjoins the insertion opening 34 and is narrower compared to the insertion opening 34 35 to engage behind the undercut 14 of the front slide end 15. A chamfer 36 The insertion opening 34 facilitates the insertion of the front slide end 15. The second mounting body 31 optionally has external transverse ribs. 37 on.

[0026] In Fign. 4a-4c The functionality of the shelf fitting 1 is shown.

[0027] In Fig. 4a The two fitting parts 10, 30 lie against each other with their front surfaces 16, 32, whereby the front sliding ends 15 are pushed back into their rear position by the front surface 32 against the action of the compression spring 13. Fig. 4b The first fitting part 10 is shifted laterally to the right relative to the second fitting part 30 until the front slider ends 15, driven by the compression spring 13, are in the insertion direction 17a have entered the insertion openings 34. In doing so, the gear 19 is rotated counterclockwise by the rack 18.

[0028] In Fig. 4c The first fitting part 10 is shifted further to the right relative to the second fitting part 30 until the inserted front slider ends 15 each engage with their undercut 14 in the slot opening 35 and engage behind the slot opening 35 in the insertion direction 17a. This locks the first fitting part 10 to the second fitting part 30 against the insertion direction 17a.

[0029] As in Fig. 5 The first fitting part 10 with its first mounting body 11 is shown in a horizontal end-face recess (e.g. slotted hole or milling). 4of the shelf 2 and the second fitting part 30 with its second mounting body 31 in a horizontal recess (e.g. slotted hole drilling or milling) 5 mounted on the side wall 3. Preferably, the front 16 of the first mounting body 11 is flush with the shelf 2 and the front 32 of the second mounting body 21 is flush with the side wall 3.

[0030] In Fign. 6a-6d The individual assembly steps for connecting the shelf 2 to the side wall 3 using the shelf fitting 1 are shown.

[0031] The shelf 2 is first inserted at an angle between two vertical side walls 3 ( Fig. 6a ) and then aligned into the horizontal position, whereby the front slider ends 15 are pushed back into their rear position by the side wall 3 against the action of the compression spring 13 ( Fig. 6b ). The tray 2 is moved laterally in the vertical and depth direction until the front sliding ends 15, driven by the compression spring 13, enter the insertion openings 34 ( Fig. 6c ). Shelf 2 is pushed further back against side wall 3 (direction of arrow). A ), until the front slider ends 15 have each entered the slot opening 35 with their undercut 14 and engage behind the slot opening 35 in the insertion direction 17a ( Fig. 6d A suit contour that slopes diagonally backwards 38 ( Fig. 8 The feature on the front 32 causes the front sliding ends 15, and thus also the first fitting part 10, to be drawn into contact with the second fitting part 30. A constriction in the slot opening 35 (not shown) provides noticeable feedback when the end position is reached and ensures that the end position is fixed.

[0032] The shelf fitting 1 allows for tool-free installation, and the installed shelf fitting 1 is virtually invisible. Only one hole is required. 6 Instructions for disconnecting the connection can be seen in tray 2.

[0033] The disassembly process proceeds in reverse to the described assembly process. The shelf 2 is pulled forward until the front sliding ends 15 are again in the insertion openings 34. A tool, e.g., a screwdriver, is inserted through the opening 6 in the shelf 2 and through the access opening 23 of the first fitting part 10, and the gear 19, as shown in the view of the Fign. 4a-4c , rotated clockwise. This pushes the slider 12 backward into a rear position, where it is locked to the first mounting body 11 by means of the locking lugs 25. This process is repeated for all existing shelf fittings 1, after which the shelf 2 can be removed.

[0034] From Fig. 3 This differs in Fig. 7 The second fitting part 30 shown differs only in that the slot opening 35 connects vertically, here upwards, to the insertion opening 34. During assembly, the shelf 2 is moved laterally downwards to lock the first fitting part 10 to the second fitting part 30.

[0035] From Fig. 1 The one in Fig. 8 The shelf fitting 1 shown is distinguished solely by the fact that the front sliding ends 15 have a rectangular or square outer contour. Alternatively, a different polygonal or oval (elliptical) outer contour is also possible. The opening contour of the insertion opening 34 is accordingly adapted to the outer contour of the front sliding ends 15.

[0036] From the shelf fitting 1 of the Fign. 1-3 The one in Fign. 9-11 shown shelf fitting 101 because of the fact that with the first fitting part 110 the first mounting body 111no gear and no access opening and the slider 112 do not have a rack and pinion, and that the second fitting part 130 the front 132 of the second mounting body 131 Each has an additional opening. 139 features which are located on the slot opening 135 far side of the keyhole 133 into the insertion opening 134 It opens. The additional opening 139 has a sloping opening bottom. 140, whose depth is related to the front 132 T , viewed in the direction away from the insertion opening 134, decreases continuously to the level of the front face 132. The depth T 0 at the insertion opening 134 corresponds to a minimum immersion depth of the front slide end 115, which is determined by the sum of the distance a the front face to the undercut 114 of the front slider end 115 and the thickness d the opening wall defining the slot opening 135 141of the second mounting body 131 is defined, i.e., T 0 ≥ a+d.

[0037] The second fitting part 130 optionally has a pull contour running diagonally backwards along the slot opening 135. 138 for the undercut 114 of the front slide end 115 in order to bring the first and second fitting parts 110, 130 into mutual contact. The first mounting body 111 can optionally consist of two housing halves, in particular of identical construction. 121 be formed, each with a guide recess on the inside. 122 for the slide 112. Optionally, the first mounting body 111 can have external projections. 126 and outer transverse ribs 127 and the second mounting body 131 outer transverse ribs 137 exhibit.

[0038] In Fign. 12a-12e The functionality of the shelf fitting 101 is shown.

[0039] In Fig. 12a The two fitting parts 110, 130 are positioned with their front sides facing outwards.116 , 132 are connected to each other, and the first fitting part 110 is laterally displaced relative to the second fitting part 130 until the front sliding ends 115, driven by the compression spring 113 , into the insertion openings 134 in the insertion direction 117a have occurred.

[0040] In Fig. 12b The first fitting part 110 is laterally displaced to the right relative to the second fitting part 130 until the inserted front slider ends 115 have each entered the slot opening 135 with their undercut 114 and engage behind the opening wall 141 in the insertion direction 117a. This locks the first fitting part 110 to the second fitting part 130 against the insertion direction 117a.

[0041] For disassembly, the first fitting part 110 is moved laterally to the left relative to the second fitting part 130 until the front sliding ends 115 have emerged from the slot opening 135 and are pushed over the insertion openings 134 and meet the sloping opening base 140 ( Fig. 12c ). As the first fitting part 110 is moved further laterally to the left, the front slider ends 115 are then pushed back against the sloping opening base 140 - and thus also the slider 112 - against the force of the compression spring 113 ( Fig. 12d ), until they finally lie in the rear slider position on the front 132 ( Fig. 12e ).

[0042] In Fign. 13a-13e The individual assembly steps for connecting the shelf 2 to the side wall 3 using the shelf fitting 101 are shown.

[0043] The shelf 2 is first inserted at an angle between two vertical side walls 3 ( Fig. 13a ) and then aligned into the horizontal position, whereby the front slider ends 115 are pushed back into their rear position by the side wall 3 against the action of the compression spring 113 ( Fig. 13b ). The tray 2 is moved laterally in the vertical and depth direction until the front sliding ends 115, driven by the compression spring 113, enter the insertion openings 134 ( Fign. 13c, 13d ). The tray 2 is pushed further backwards against the side wall 3 (direction of arrow A) until the front sliding ends 115 have each entered the slot opening 135 with their undercut 114 and engage behind the opening wall 141 in the insertion direction 117a ( Fig. 13e The shelf fitting 101 allows for tool-free assembly and disassembly, with the assembled shelf fitting 101 being invisible.
