Description

Technical Field

[0001] The invention relates to a furniture fitting for movably mounting at least one furniture part on a furniture carcass.

[0002] The invention further relates to a piece of furniture having a furniture carcass and at least one furniture part mounted movably relative to the furniture carcass, in particular a furniture flap pivotable relative to the furniture carcass about a horizontal axis, wherein the piece of furniture has at least one furniture fitting of the type to be described.

[0003] Finally, the invention relates to a method for producing a furniture fitting of the type to be described. Background Art

[0004] The articulated connection of two components of a furniture fitting is usually achieved by a forming method, the so-called necking (Aushalsen) or collar stretching (Kragenziehen). In a first step, a recess, for example a cylindrical hole, is installed in a first component of the furniture fitting. Subsequently, a necking tool (Aushalswerkzeug) is introduced into the recess of the first component in a first direction of movement. After the necking tool has been introduced into the recess, the necking tool is rotated and the forming punch of the necking tool is moved out. Subsequently, the circumferential edge of the recess is slowly pulled in a second direction of movement opposite to the first direction of movement by the rotating forming punch until finally a characteristic neck or flange is formed. The neck or flange constitutes a pivot bearing with an enlarged bearing surface, on which the second component of the furniture fitting can be pivotally supported. However, the formation of the neck or flange also has the disadvantage that the structural height of the furniture fitting is increased.

[0005] Recently, furniture fittings, in particular adjustment drives for furniture flaps, have begun to be fully or partially integrated into the furniture panel of the furniture body. In this way, the furniture fitting is barely visible anymore. It is therefore a primary aim to design the furniture fitting as compactly as possible, i.e. with a low thickness, so that in the assembled state of the furniture fitting the cover layer of the furniture panel remains on both sides of the housing of the furniture fitting. Summary of the invention

[0006] The object of the present invention is to specify a furniture fitting of the type mentioned at the outset which is intended to be compact in design and to have a long service life.

[0007] According to the invention, this is solved by the features described below.

[0008] According to the present invention, the furniture fitting has at least one first component and at least one second component, wherein the first component and the second component are connected to each other via at least one pivot bearing with a support shaft, and the at least one first component has at least one first wall, and the at least one pivot bearing has at least one capillary sheet with at least one second wall, wherein the second wall is separated from the first wall of the first component by a preferably annular gap with a gap width, wherein the gap width at least partially decreases radially toward the support shaft so that the lubricant injected into the gap can be transported radially toward the support shaft and / or along the support shaft by capillary forces, wherein the second wall of the at least one capillary sheet extends obliquely in the first gap section and extends parallel to the first wall of the first component in the second gap section.

[0009] In tribology (ie the tribology which deals with friction, wear, lubrication and the optimization of friction elements in relative motion), the supply of lubricant to the bearing points is one of the important factors with regard to the service life of the swivel bearing.

[0010] The invention is now based on the basic idea of ​​improving the flow of lubricant into the narrow gap of a pivot bearing of a furniture fitting by means of capillary sheets, wherein the lubricant is thus drawn into the gap by capillary action and the lubricant can be distributed in an improved manner in the region of the pivot bearing. In this way, the pivot bearing can be adequately supplied with lubricant and the service life of the furniture fitting is increased. In addition, the production of a neck or a flange in the region of the bearing point can be omitted. This has the advantage that the furniture fitting can be designed compactly, that is to say without thick rod groups.

[0011] According to one embodiment, it can be provided that the second wall of the at least one capillary extends obliquely in the first gap section and extends parallel to the first wall of the first component in the second gap section. Preferably, the two walls enclose an angle of between 15° and 45° relative to each other in the first gap section, particularly preferably an angle of 30°.

[0012] The obliquely extending first gap section thus forms a reservoir for the lubricant, from which the lubricant can be distributed in a radial direction toward the bearing shaft and along the bearing shaft.

[0013] The at least one capillary sheet can be configured at least partially in a truncated cone shape in cross section. It can be provided that the smaller of the two base surfaces of the truncated cone faces the first component.

[0014] The at least one first component can have at least two partial sections which are spaced apart from one another in the direction of the bearing axis, wherein the second component is arranged at least in places between the two partial sections of the first component.

[0015] The bearing pin can be designed, for example, as a rivet, wherein at least one capillary web is accommodated between a preferably widened end region of the rivet and the first wall of the first component.

[0016] According to another embodiment, at least one capillary sheet may be arranged at least partially between the two components.

[0017] According to a preferred embodiment, the furniture fitting comprises a housing and at least one adjusting arm arrangement which is pivotable relative to the housing, the adjusting arm arrangement comprising at least two adjusting arms, wherein the two adjusting arms are connected to one another via the at least one pivot bearing.

[0018] The furniture according to the invention comprises a furniture carcass and at least one furniture part mounted movably relative to the furniture carcass, in particular a furniture flap pivotable relative to the furniture carcass about a horizontal axis, wherein the furniture comprises at least one furniture fitting of the described type.

[0019] It is preferably provided that the furniture carcass has at least one furniture panel and that the housing of the furniture fitting is accommodated substantially completely within the furniture panel of the furniture carcass in the assembled state.

[0020] The method for producing a furniture fitting according to the invention is characterized in that the method comprises the following steps:

[0021] - the two components of the furniture fitting are connected to one another via a bearing axis of the at least one pivot bearing, wherein the at least one capillary sheet is arranged on the bearing axis with a gap formed between the two walls,

[0022] - inject lubricant into the gap, and

[0023] - The lubricant is transported radially toward the support shaft and / or along the support shaft by capillary forces.

[0024] According to one embodiment, it can be provided that the bearing shaft is designed as a rivet and at least one end region of the rivet is deformed in a further method step, preferably the at least one capillary being accommodated between the first wall and the deformed end region of the rivet.

[0025] Preferably, it is provided that the at least one capillary web is designed as a component separate from the two components. However, it is also conceivable that the at least one capillary web is designed in one piece with one of the two components. BRIEF DESCRIPTION OF THE DRAWINGS

The spring device 10 for applying force to the adjusting arm device 5 can have a plurality of helical springs, in particular compression springs. The spring device 10 is supported with a first end region on a support part 14, which is supported pivotably about an axis of rotation 15. A second end region of the spring device 10 presses against a nut 16, which is supported movably along a threaded spindle 20 via an adjusting device 17.

[0041] In the embodiment shown, the threaded spindle 20 is arranged on an intermediate lever 18 that is pivotable about an axis of rotation 19. By actuating a rotatably mounted operating element 17a of the adjusting device 17, the nut 16 can be moved along the threaded spindle 20, wherein the distance between the nut 16 and the axis of rotation 19 of the intermediate lever 18 and thus the torque of the spring device 10 applied to the adjusting arm device 5 can be adjusted. As is known per se, the adjusting arm device 5 can be detachably locked with an accessory element 22 to be fixed to the movable furniture part 3.

[0042] The furniture fitting 4 has a first component 5a and at least one second component 5b, which are connected to each other in an articulated manner via at least one pivot bearing 21 with a bearing axis 23. The adjusting arm device 5 comprises a plurality of adjusting arms 31a, 31b, 31c, which are formed by the components 5a, 5b, 5c.

[0044] The pivot bearing 21 comprises at least one capillary piece 24a with at least one second wall 27a arranged on the support shaft 23, wherein the second wall 27a of the capillary piece 24a is separated from the first wall 26a of the first component 5a by a gap 28a having a gap width (ΔX). The gap width (ΔX) decreases radially toward the support shaft 23, so that the lubricant 30 injected into the gap 28a can be transported radially toward the support shaft 23 and / or along the support shaft 23 by capillary force.

[0045] According to one embodiment, it can be provided that the second wall 27a of the at least one capillary piece 24a extends obliquely in the first gap section and extends in parallel to the first wall 26a of the first component 5a in the second gap section.
