Description

Technical Field

[0001] The present invention relates to a fitting for movably supporting a swivel element, particularly a furniture part, a door or a window, relative to a stationary support, having the features described in the preamble of claim 1, and to furniture provided with such a fitting.

[0002] Such fittings are known, for example, from document A50977 / 2018 by the applicant, or from one of the documents of US Patent Application Publication No. 2004 / 0252045, German Utility Model No. 20207036, European Patent Application Publication No. 3343152 and International Publication No. 2020 / 232490. This document proposes a joint mechanism comprising at least five joint axes and a plurality of joint levers. A disadvantage of such a fitting is the relatively complex configuration of the joint mechanism. This, on the one hand, increases the material requirements and the manufacturing effort, which results in higher costs. On the other hand, in the complex mechanical configuration of the joint mechanism, contamination, defects, etc. are likely to occur.

[0003] Document A50977 / 2018 also discloses furniture provided with such hinges. In this case, the swivel element can preferably cover at least a predetermined section, and preferably substantially completely, of the end face of the side wall. Thereby, when the furniture is viewed from the front side, there is a smooth surface as a whole without a step or gap that can be confirmed from the front side being formed between the side wall and the swivel element. It is desirable that this positive effect is maintained.

[0004] Therefore, the objective technical problem of the present invention is to provide a fitting improved over the prior art, in which the disadvantages of the prior art are at least partially eliminated, and in particular the above-mentioned positive effect is maintained. Furthermore, it is desirable to provide furniture provided with such a fitting.

[0005] This problem is solved by the features described in claim 1 and claim 10.

[0006] Accordingly, a guide device is provided, which is linearly movable in or within one of the two fitting parts, and is pivotally connected to the other of the two fitting parts via a third joint shaft, the third joint shaft being separate from the first joint shaft and / or the second joint shaft and being spaced apart from the first joint shaft and / or the second joint shaft, and there are at least two, preferably exactly two, joint levers, the at least two joint levers being pivotally connected to the first fitting part via the first joint shaft and to the second fitting part via the second joint shaft.

[0007] The guide device allows for a reduction to three joint axes, thereby further reducing the complexity of the joint mechanism and, consequently, the fittings. The arrangement of the joint axes allows the pivot element to cover at least a predetermined portion of the end face of the side wall, preferably substantially completely.

[0008] Furthermore, the pivoting element is already stabilized by the fittings. In addition, vertical load removal can be performed simply via a single joint lever.

[0009] Furthermore, damping of the rotational motion of the rotational element can be easily achieved in the proposed fitting using a perforated damper.

[0010] If a second joint lever is provided, it can withstand higher forces and moments. Furthermore, another joint lever additionally stabilizes the pivoting motion of the fitting.

[0011] With respect to furniture, it is specified that the furniture includes a swivel element, a stationary support, and at least one fitting according to the present invention, wherein the swivel element is formed in the form of a movable furniture part, and the stationary support is formed in the form of a furniture cabinet.

[0012] Advantageous embodiments of the present invention are defined in the dependent claims.

[0013] According to a preferred configuration of the present invention, at least one joint lever may be defined as being substantially L-shaped.

[0014] The L-shaped configuration of at least one joint lever allows the pivot element to set a trajectory in relation to the arrangement of the joint axis.

[0015] The guide device may be defined to include a guide element and a support element, wherein the guide element is supported within the support element in a linearly movable manner.

[0016] Furthermore, the guide element may be provided with a coupling section through which the guide element is pivotally coupled to one of the two metal parts via a third joint axis.

[0017] This makes it possible to implement the guide device in a simple and straightforward manner.

[0018] According to an advantageous embodiment of the present invention, the guide element may be provided to have a circular or polygonal cross-section.

[0019] Therefore, depending on the requirements, a cross-section can be selected that allows or prevents the rotation of the guide member within the support element.

[0020] The specification may stipulate that the support element includes at least one, preferably two, sliding elements.

[0021] In particular, it was found to be advantageous if at least one sliding element is positioned within a notch of the first metal fitting member, and the guide element is guided to move linearly within the sliding element.

[0022] This enables the material of the slide element to be selected independently of the material of the fitting. Furthermore, the slide element can be easily replaced in case of wear.

[0023] Advantageously, it may be specified that the second fitting part is formed from two parts.

[0024] Particularly preferably, it may be specified that the second joint axis is arranged corresponding to the first part of the second fitting, and the third joint axis is arranged corresponding to the second part of the second fitting.

[0025] Through the configuration consisting of two parts of the second fitting part, a separate and spaced-apart configuration of the joint shafts can be easily realized. Furthermore, material can be saved in the second fitting part.

[0026] Regarding furniture, it may be specified that the swivel element is movable by means of a fitting between a first position in which the swivel element at least partially covers the end face of the side wall and a second position in which the swivel element is movable in the depth direction of the stationary support.

[0027] Thereby, when the furniture is viewed from the front, there is a smooth surface as a whole without forming a step or gap that can be confirmed from the front between the side wall and the swivel element. Therefore, the evaluation of the visual overall image of the furniture is significantly improved.

[0028] Advantageously, it may be specified that the stationary support has at least one side wall and the swivel element is arranged substantially parallel to the side wall in the second position.

[0029] The parallel arrangement of the side wall and the swivel element in the first position enables easy access to the interior of the furniture in the second position.

[0030] Particularly advantageously, the stationary support has at least two side walls, the at least two side walls form a hollow chamber, and it may be defined that a swivel element is runnable in the depth direction of the stationary support in the second position within this hollow chamber.

[0031] That is, in the second position, the swivel element is hardly visible anymore, so that, on the one hand, the swivel element does not extend beyond the furniture, and on the other hand, a visually attractive overall image of the furniture is promoted.

[0032] According to an advantageous embodiment of the invention, it may be defined that at least two fittings according to the invention are provided.

[0033] Thereby, the stability of the furniture is significantly enhanced.

[0034] Another detail and advantage of the invention will be explained in detail below with reference to the description of the drawings of the embodiments illustrated in the drawings.

Brief Description of the Drawings

[0035] [Figure 1a] It is a perspective view showing the furniture in the first position. [Figure 1b] It is a perspective view showing the furniture in the second position. [Figure 2] It is an exploded view of the fitting. [Figure 3a] It is a plan view showing a part of the furniture in one step when the furniture is shifted from the first position to the second position. [Figure 3b] It is a plan view showing a part of the furniture in another step when the furniture is shifted from the first position to the second position. [Figure 3c] It is a plan view showing a part of the furniture in yet another step when the furniture is shifted from the first position to the second position. [Figure 3d] It is a plan view showing a part of the furniture in yet another step when the furniture is shifted from the first position to the second position. [Figure 4a] This is a perspective view showing the hardware in one step during the transfer of furniture from the first position to the second position. [Figure 4b] This is a perspective view showing the hardware in another step during the transfer of furniture from the first position to the second position. [Figure 4c] This is a perspective view showing the hardware in yet another step during the transfer of furniture from the first position to the second position. [Figure 4d] This is a perspective view showing the hardware in yet another step during the transfer of furniture from the first position to the second position.

[0036] Figure 1a shows a perspective view of furniture 100 in a first position, and Figure 1b shows the same furniture 100 in a second position.

[0037] It can be seen that the furniture 100 has a fixed support 102 in the form of the furniture body. Furthermore, a swivel element 101 in the form of a door can be seen.

[0038] In the first position shown in Figure 1a, the pivot element 101 covers the end face 103a of the side wall 103. Furthermore, the pivot element 101 is flush with the folding sliding door 105, which in the first position creates a consistent furniture front and, consequently, a visually appealing overall appearance of the furniture 100.

[0039] It can also be seen that a second side wall 103 is provided, and the side wall 103 forms a hollow chamber 104.

[0040] In the second position shown in Figure 1b, the slewing element 101 is positioned substantially entirely within the hollow chamber 104. Therefore, good access to the internal space 106 is possible. Furthermore, the slewing element 101 does not extend into the space, and thus it does not obstruct anything.

[0041] In this embodiment, a folding sliding door 105 is provided in the portion of the furniture 100 that connects to the pivot element 101, and the folding sliding door 105 can be placed in a hollow chamber 104' formed by two other side walls 103'.

[0042] However, it may be specified here that no other part is connected to the swivel element 101, meaning that the stationary support 102 has substantially the same width as the swivel element 101. However, multiple identical swivel elements 101 may be arranged side by side.

[0043] Figure 2 shows an exploded view of the metal fitting 1. The first metal fitting part 2 and the second metal fitting part 3, which consists of two parts, are visible, and the second metal fitting part 3 consists of the first part 3a and the second part 3b.

[0044] The first metal fitting portion 2 has a notch 2b. Two support elements 5e can be inserted into this notch 2b. The support elements 5e may be made from a different material than the first metal fitting portion 2, for example, to achieve better sliding properties. It is also possible that there is only one support element 5e, or three or more support elements 5e.

[0045] A guide element 5b is guided within the support element 5e. In this case, both the support element 5e and the guide element 5b have a circular cross-section, but virtually any other cross-section is conceivable.

[0046] The guide element 5b has a coupling section 5d, through which the guide element 5b may be coupled to the second part 3b of the second mounting fixture 3. For this purpose, a hole is provided in the coupling section 5d. This hole can accommodate a coupling pin 6. The second part 3b is also provided with a hole for accommodating the coupling pin 6. This enables a pivotal connection between the guide element 5b and the second metal fitting part 3.

[0047] The joint lever 4 is also pivotally connected to the first metal fitting portion 2 or the first portion 3a of the second metal fitting portion 3 via a connecting pin 6. In this embodiment, two joint levers 4 are provided, which has the advantage of being able to withstand higher forces and moments. However, there may be only one joint lever 4 or more than two joint levers 4.

[0048] As can be seen in the following diagram, both joint levers 4 are pivotally connected to the first fitting part 2 or the second fitting part 3 via the same joint axes 2a and 3c. In other words, the joint levers 4 are not independent of each other, but can simply move simultaneously with each other. Therefore, the second joint lever 4 functions solely for the structural reinforcement of the first joint lever 4.

[0049] Figures 3a to 3d show plan views of parts of the furniture 100 at various steps during the transition of the furniture 100 from the first position to the second position, and Figures 4a to 4d show perspective views of the metal fittings 1 at the same steps.

[0050] In Figures 3a and 4a, the fitting 1 and thus the furniture 100 are in the first position. It can be seen that the swivel element 101 substantially completely covers the end face 103a of the side wall 103. The guide element 5b is substantially entirely located within the hollow chamber 104.

[0051] In Figures 3b and 4b, the pivot element 101 has already been pivoted to a certain extent. It can be seen that the guide element 5b, guided within the support element 5c, is being moved linearly. The joint lever 4 is also being pivoted. A trajectory is defined through the joint lever 4 and the arrangement of the joint axes 2a, 3c, and 5a, and the pivot element 101 is pivoted along this trajectory.

[0052] In Figures 3c and 4c, the pivot element 101 is further pivoted, and in Figures 3d and 4d, it is pivoted to a second position. It can be seen that, due to the arrangement of the joint lever 4 and joint axes 2a, 3c, and 5a, the pivot element 101 covers the end face 103a of the side wall 103 in the first position, but is positioned parallel to the side wall 103 in the second position, and is guided to move into the hollow chamber 104 formed by the side wall 103 and another side wall 103. This movement is performed in the depth direction Z of the stationary support 102 or the hollow chamber 104. [Explanation of symbols]
