Description

[0001] The invention relates to a piece of furniture comprising a pivoting element, a stationary support and at least one fitting for the movable mounting of the pivoting element, in particular of a furniture part, relative to the stationary support, with the features of the preamble of claim 1.

[0002] Such a fitting is known, for example, from the applicant's own document AT 521841 A1, WO2018 / 129574A1 or also from one of the documents US 2004 / 0252045 A1, DE 202 07 036 U1, EP 3 343 152 A1 and WO 2020 / 232490 A1. This document proposes a joint mechanism with at least five joint axes and several joint levers. The disadvantage of such a fitting is the relatively complex design of the joint mechanism. On the one hand, this leads to increased material requirements and manufacturing effort, which entails higher costs. On the other hand, a complex mechanics of the joint mechanism is more susceptible to contamination, defects, etc.

[0003] AT 521841 A1 also discloses a piece of furniture with such a hinge. A pivoting element can cover at least partially, preferably substantially completely, an end face of a side wall. This creates a smooth surface when viewed from the front—without forming a step or gap visible from the front between the side wall and the pivoting element. This positive effect is to be maintained.

[0004] DE102009009719A1 discloses a furniture fitting with a guide device.

[0005] The objective technical problem of the present invention is therefore to provide a piece of furniture which is improved over the prior art and in which the disadvantages of the prior art are at least partially eliminated and which in particular retains the above-mentioned positive effect.

[0006] This problem is solved by the features of claim 1.

[0007] Accordingly, a guide device is provided, wherein the guide device is mounted so as to be linearly displaceable on or in one of the two fitting parts and is articulated to the other of the two fitting parts via a third joint axis, wherein the third joint axis is formed separately and spaced from the first joint axis and the second joint axis, wherein at least two, preferably exactly two, articulated levers are provided, wherein the at least two articulated levers are each articulated to the first fitting part via the first joint axis and articulated to the second fitting part via the second joint axis.

[0008] The guide device enables the reduction to three joint axes, which in turn reduces the complexity of the joint mechanism and thus of the fitting. The arrangement of the joint axes allows a pivoting element to cover at least part of the end face of a side wall, preferably essentially completely.

[0009] In addition, the swivel element is already stabilized by the fitting. Furthermore, vertical load transfer can be achieved via a single articulated lever.

[0010] Furthermore, damping of the pivoting movement of the pivoting element in a proposed fitting can easily be achieved by means of a drill-in damper.

[0011] According to the invention, the piece of furniture comprises a pivoting element, a stationary support and at least one fitting, wherein the pivoting element is designed in the form of a movable furniture part and the stationary support is designed in the form of a furniture body.

[0012] According to the invention, it is provided that the pivoting element is movable by means of the fitting between a first position in which the pivoting element at least partially covers an end face of the side wall and a second position in which the pivoting element is movable in a depth direction of the stationary support.

[0013] This creates a smooth surface when viewed from the front, without any visible step or gap between the side panel and the swivel element. This significantly enhances the overall visual appearance of the furniture.

[0014] Advantageous embodiments of the invention are defined in the dependent claims.

[0015] According to an advantageous embodiment of the invention, it can be provided that the at least one articulated lever is substantially L-shaped.

[0016] The L-shaped design of the at least one articulated lever, in conjunction with the arrangement of the joint axes, makes it possible to specify a trajectory along which a pivoting element can be pivoted.

[0017] It can also be provided that the guide device comprises a guide element and a bearing element, wherein the guide element is mounted in the bearing element in a linearly displaceable manner.

[0018] In addition, it can be provided that the guide element has a connecting section via which the guide element is connected in an articulated manner to one of the two fitting parts via the third joint axis.

[0019] This represents simple and uncomplicated options for implementing a guidance device.

[0020] According to an advantageous embodiment of the invention, it can be provided that the guide element has a circular or polygonal cross-sectional area.

[0021] Depending on the requirements, a cross-section can be selected which allows or prevents rotation of the guide element in the bearing element.

[0022] It can be provided that the bearing element comprises at least one sliding element, preferably two sliding elements.

[0023] It has proven particularly advantageous if the at least one sliding element is arranged in a recess in the first fitting part, wherein the guide element is guided in the sliding element in a linearly displaceable manner.

[0024] This makes it possible to select the material of the sliding elements independently of the material of the fittings. Furthermore, the sliding elements can be easily replaced if they become worn.

[0025] Preferably, it can be provided that the second fitting part is formed in two parts.

[0026] Particularly preferably, it can be provided that the second joint axis is assigned to a first part of the second fitting and the third joint axis is assigned to a second part of the second fitting.

[0027] The two-part design of the second fitting component makes it easy to create separate and spaced joint axes. Furthermore, material can be saved in the second fitting component.

[0028] Preferably, it can be provided that the pivoting element is arranged substantially parallel to the side wall in the second position.

[0029] Due to the parallel arrangement of the swivel element with the side wall in the second position, the interior of the furniture is easily accessible in the second position.

[0030] Particularly preferably, it can be provided that the stationary support has at least two side walls, wherein the at least two side walls form a cavity in which the

[0031] Swivel element can be moved in the second position in the depth direction of the stationary support.

[0032] In the second position, a pivoting element is barely visible, which, on the one hand, prevents the pivoting element from extending beyond the furniture and, on the other hand, promotes a visually appealing overall appearance of the furniture. According to a preferred embodiment of the invention, at least two fittings according to the invention can be provided.

[0033] This significantly increases the stability of a piece of furniture.

[0034] Further details and advantages of the present invention are explained in more detail below with reference to the exemplary embodiments shown in the drawings. Fig. 1a shows a perspective view of a piece of furniture in a first position, Fig. 1b shows a perspective view of a piece of furniture in a second position, Fig. 2 shows an exploded view of a fitting, Fig. 3a-d shows plan views of a part of a piece of furniture at various steps when transferring the piece of furniture from a first to a second position, and Fig. 4a-d shows perspective views of a fitting at various steps when transferring the piece of furniture from a first to a second position.

[0035] The Figure 1 shows a perspective view of a piece of furniture 100 in a first position, the Figure 2 the same furniture 100 in a second position.

[0036] It can be seen that the furniture 100 has a stationary support 102 in the form of a furniture body. A pivoting element 101 in the form of a door leaf is also visible.

[0037] In the first position according to Figure 1a the pivoting element 101 covers an end face 103a of a side wall 103. The pivoting element 101 further adjoins a folding sliding door 105 flush, which in the first position results in a continuous furniture front and thus a visually appealing overall appearance of the furniture 100.

[0038] It can also be seen that a second side wall 103 is provided, wherein the side walls 103 form a cavity 104.

[0039] In the second position according to Figure 1bThe pivoting element 101 is arranged substantially entirely within the cavity 104. Thus, an interior space 106 is easily accessible. Furthermore, the pivoting element 101 does not extend into a space, so the pivoting element 101 is not in the way.

[0040] In the present embodiment, a part of the furniture 100 adjoining the pivoting element 101 is equipped with a folding sliding door 105, which can be arranged in a cavity 104' formed by two other side walls 103'.

[0041] However, it can also be provided that no further part is connected to the pivoting element 101, ie, that the stationary support 102 is essentially the same width as the pivoting element 101. However, several identical pivoting elements 101 can also be arranged next to one another.

[0042] The Figure 2shows an exploded view of a fitting 1. A first fitting part 2 and a two-part second fitting part 3, consisting of a first part 3a and a second part 3b, can be seen.

[0043] The first fitting part 2 has a recess 2b into which two bearing elements 5e can be inserted. The bearing elements 5e can be made of a different material than the first fitting part 2, for example, to achieve better sliding properties. It is also conceivable that only one bearing element 5e or more than two bearing elements 5e are provided.

[0044] A guide element 5b is guided in the bearing elements 5e. In this case, both the bearing elements 5e and the guide element 5b have a circular cross-section, but essentially any other cross-section is conceivable.

[0045] The guide element 5b has a connecting section 5d, via which the guide element 5b can be connected to the second part 3b of the second fitting part 3. For this purpose, a bore is provided in the connecting section 5d, which can accommodate a connecting pin 6. Bores for receiving the connecting pin 6 are also provided in the second part 3b, thus creating an articulated connection between the guide element 5b and the second fitting part 3.

[0046] The articulated levers 4 are also connected to the first fitting part 2 or the first part 3a of the second fitting part 3 via connecting pins 6. In the present example, two articulated levers 4 are provided, which has the advantage of being able to absorb higher forces and moments. However, more than two articulated levers 4 can also be provided.

[0047] In particular, the following figures also show that both articulated levers 4 are articulated to the first fitting part 2 and the second fitting part 3, respectively, via the same joint axes 2a, 3c. The articulated levers 4 cannot move independently, but only simultaneously with one another. The second articulated lever 4 thus serves only to structurally reinforce the first articulated lever 4.

[0048] The Figures 3a to 3d show plan views of a part of a piece of furniture 100 at various steps when transferring the piece of furniture 100 from a first to a second position and the Figures 4a to 4d Perspective views of a fitting 1 with the same steps.

[0049] In the Figure 3a and 4aThe fitting 1, and thus the piece of furniture 100, is in a first position. It can be seen that the pivoting element 101 essentially completely covers an end face 103a of the side wall 103. The guide element 5b is essentially completely arranged within the cavity 104.

[0050] In the Figure 3b and 4b The pivoting element 101 has already pivoted a certain distance. It can be seen that the guide element 5b, which is guided in the bearing elements 5c, has been linearly displaced. The articulated levers 4 have also been pivoted. A trajectory is defined via the articulated levers 4 and the arrangement of the joint axes 2a, 3c, and 5a, along which the pivoting element 101 is pivoted.

[0051] In the Figure 3c and 4c the swivel element 101 is even further and in the 3d figures and 4dpivoted into the second position. It can be seen that the pivoting element 101 is guided by the articulated levers 4 and the arrangement of the joint axes 2a, 3c, 5a such that in the first position, the end face 103a of the side wall 103 is concealed, but in the second position, it is arranged parallel to the side wall 103 and can be moved into a cavity 104 formed by the side wall 103 and another side wall 103. This movement takes place in a depth direction Z of the stationary support 102 or the cavity 104. List of reference symbols:
