Description

[0001] The present invention relates to a table arrangement and a piece of furniture.

[0002] Well-known, flexibly designed furniture pieces, such as those from EP 2 804 506 B1, allow for a modifiable arrangement of a first and second panel via a guide track positioned between the panels. The first panel serves as a fixed point relative to which the second panel moves. The second panel is initially positioned congruently above the first panel. Through a translational, rotational, and then translational movement guided by the track, the second panel can be moved from the first position to the second position.

[0003] In the second position, the second panel is positioned at a right angle to the first panel. In familiar furniture designs, the weight of the panel is supported by a guide rail and a support. The support is attached, for example, to one end of the second panel and therefore moves with the second panel when moving from the first to the second position (and vice versa). In the second position, the support is perpendicular to the second panel and braces it against the floor.

[0004] The support allows for the storage of the second panel in the known furniture designs. However, the support's own weight must always be moved along with the second panel. Furthermore, the support is attached to one end of the second panel, meaning that in the second position, the support is far removed from the first panel, which serves as the fixed point. This eliminates the potential for further flexible arrangement of the furniture.

[0005] Against this background, one object of the present invention is to provide an improved table arrangement.

[0006] According to a first aspect, a table arrangement is defined as comprising a base surface; an angular, in particular rectangular, plate with a free end and a coupling section, wherein the free end and the coupling section adjoin opposite edges of the angular plate; a coupling arrangement between the base surface and the coupling section, which enables translation and rotation of the angular plate relative to the base surface, wherein the rotation is about an axis of rotation arranged perpendicular to the base surface, with a bearing element which lies on the axis of rotation and supports the angular plate in at least a first position against the base surface;and a holding device for compensating a tilting moment acting around the bearing element, caused in the first position of the square plate and essentially by the weight of the free end, wherein the holding device is arranged in a region of the coupling section.

[0007] The translation occurs, in particular, along a line segment with a starting point and an endpoint. The axis of rotation is, in particular, displaceable along a line segment of the translation.

[0008] Advantageously, the tilting moment generated by the weight of the tabletop in the first position is absorbed by the holding device located in the coupling section. This eliminates the need for additional bearing points, supports, or table legs to brace, for example, the free end of the rectangular tabletop against the floor. This allows for more flexible table arrangement within a room, as the area between the free end of the rectangular tabletop and the floor can now be utilized in the first position.

[0009] A plate is, in particular, a three-dimensional component characterized by a flat, planar shape and a small thickness. Plates can, for example, have a polygonal, especially rectangular, shape. In the case of a rectangular plate, it has, in addition to its thickness, a length and a width, where the length is greater than the width and the width, in turn, is greater than the thickness. Plates can also be circular, triangular, square, oval, freeform, L-shaped, or T-shaped.

[0010] The base can, for example, be designed as a board. In this case, the base is fixed to a floor or wall. The base can thus be considered a fixed point in the room. In other examples, the base is part of a cabinet or base unit, a chair, a table, or a chest of drawers.

[0011] For example, the support surface is arranged horizontally, particularly parallel to the floor. The support surface can also be arranged perpendicular to the floor. In other examples, the support surface is arranged at an angle between 0° and 179° to the floor.

[0012] Terms such as horizontal, level, and perpendicular describe the orientation or position of objects, for example, the support surface, relative to other objects, such as the ground. When the support surface is horizontal to the ground, the support surface and the ground form an angle of 0°. When the support surface is perpendicular to the ground, the support surface and the ground form an angle of 90°.

[0013] Due to tolerances and deviations during manufacturing and / or assembly, terms that specify a spatial dimension of an object, as well as the spatial arrangement of one object to a second object, include deviations of up to 5%, in particular deviations of up to 10%, and in particular deviations of up to 20%.

[0014] The plate can be polygonal in shape. In particular, the plate can be circular, triangular, square, oval, freeform, L-shaped, or T-shaped. The plate and the base are, for example, made of the same material. For example, the material from which the base and the plate are made could be wood, plastic, stone, metal, sheet metal, or a composite material made of, for example, two components.

[0015] The free end is, for example, an edge of the plate. If the plate is rectangular, the free end can be an edge of a long side. For example, the free end can be an edge of the short side. The free end extends, for example, from the edge of the plate towards an edge of the plate opposite that edge. The free end has, for example, a length and a width, where the length of the free end is less than the length of the plate.

[0016] The coupling section is, for example, a section, area, or end of the plate located between an edge of the long side and the free end. The coupling section has, for example, a length and a width, where the length of the coupling section is less than the length of the plate. For example, the length of the coupling section and the length of the free end equal the length of the plate.

[0017] The coupling arrangement can, for example, comprise at least one receptacle and at least one connecting element. The receptacle is suitable, for example, for receiving a connecting element. The receptacle is arranged, for example, on the base surface and / or on the plate. The connecting element can, for example, comprise pins, grooves, balls, rollers, joints, hinges, and / or magnets. In particular, the coupling arrangement is designed as a tongue and groove connection, dovetail guide, or guide track. In particular, the coupling arrangement is suitable for moving the plate relative to the base surface.

[0018] In embodiments, the coupling arrangement comprises a slide that is linearly displaceable in or on a straight guide rail, wherein the slide has a rotary table that enables rotation at a point along the guide rail, in particular at the endpoints.

[0019] In embodiments, the coupling arrangement is a coupling arrangement according to the claims of German utility model DE 20 2023 105 707 U1, wherein the mutually movable plates therein correspond to the tabletop and the plate forming the base, or correspond to the coupling plates. The bearing element of the present utility model corresponds to the first guide element at the starting point of the first guide track of DE 20 2023 105 707 U1. Reference is hereby made in full to DE 20 2023 105 707 U1.

[0020] In embodiments, the coupling arrangement is a coupling arrangement according to the claims of European Patent EP 2 804 506 B1, wherein the mutually movable plates therein correspond to the tabletop and the plate forming the base surface, or correspond to the coupling plates. The bearing element of the present utility model corresponds to the first guide pin at the starting point of the first guide track of EP 2 804 506 B1. Reference is hereby made in full to EP 2 804 506 B1.

[0021] The coupling arrangement is, for example, located on the underside of the plate and on the top side of the base surface. For example, the coupling arrangement separates the free end from the coupling section.

[0022] "Movements of objects" include, in particular, the translation and / or rotation of one object or body relative to another object or body. The plate can be considered an object.

[0023] "Translation" is specifically the displacement of an object without rotation or reflection, where all points of the object undergo the same displacement. This means that at a given moment, the velocity and acceleration of all points of the object are identical and they move along parallel trajectories. The object is moved along a specific direction and a specific distance, while its shape and orientation remain unchanged.

[0024] Rotation is, in particular, the movement of an object around an axis of rotation. The object rotates, specifically through a certain angle, or can undergo continuous rotation. Rotation is performed by the object at a specific angular velocity. During rotation, all points on the axis of rotation remain stationary, while all points of the object, at a fixed distance from the axis, move around the axis at the same angle and / or angular velocity in a circle perpendicular to the axis.

[0025] In three-dimensional space, spanned by three spatial directions, a body has six degrees of freedom, three of which are translational and three of which are rotational. The three spatial directions are specifically arranged at an angle of 90° to each other.

[0026] For example, the plate performs a sequence of movements, which may include multiple translations and rotations. For instance, the plate might first undergo a translation, then a rotation, and then another translation. By performing this sequence of movements, the plate can, for example, be moved from a first position to a second position (or vice versa).

[0027] The axis of rotation is, in particular, the axis of rotation around which the rotation is performed.

[0028] The bearing element can be designed as a connecting element as part of the coupling arrangement. For example, the bearing element is arranged on the base surface and / or the plate. The bearing element is particularly designed as a single-value bearing, whereby the bearing element restricts at least one degree of freedom of the plate. For example, the bearing element can be configured to support the plate over a surface or a point.

[0029] The holding device is specifically designed to restrict at least one degree of freedom of the plate in its first position. In particular, the bearing element and the holding device are arranged on an axis parallel to the translation. Alternatively, the bearing element and the holding device may be arranged on an axis at an angle to the translation. For example, the holding device may be designed as a snapshot.

[0030] The holding device compensates for the tilting moment, for example, by generating a reaction force. For example, the holding device is a single-value bearing. For example, in the first position, the plate and the base surface are arranged at right angles to each other.

[0031] The tipping moment is generated in particular by a weight force at the free end of the plate.

[0032] The holding device is arranged around the coupling assembly, for example. For instance, the holding device is located at a distal end of the plate relative to the free end.

[0033] In embodiments, the holding device comprises several holding devices which form a triangle with the bearing element and, in particular, span a plane perpendicular to the axis of rotation.

[0034] Advantageously, the triangular arrangement prevents the plate from tipping over.

[0035] The triangular arrangement can be oriented, in particular, towards the free end. For example, the triangular arrangement is oriented in a direction opposite the free end.

[0036] According to a further embodiment, at least one holding device comprises a first holding element on the base surface and a corresponding second holding element on the underside of the square plate in the first position of the plate, wherein in particular a constraint moment is established as a reaction to the tilting moment.

[0037] Advantageously, the design of the first and / or second retaining element can further stabilize the plate.

[0038] For example, in the first position of the plate, all forces acting on the plate are directed parallel to the axis of rotation.

[0039] According to another embodiment, the first retaining element and the second retaining element are arranged such that they interlock when the plate is translated to the first position of the plate.

[0040] Advantageously, the holding device in the first position allows for a releasable connection between the plate and the base surface using simple means.

[0041] In particular, the first or second retaining element forms an undercut. For example, the first and second retaining elements can be designed as L-shaped parts, with one leg of each L interlocking. Advantageously, the identical design of the first and second retaining elements allows for the use of identical parts, thereby reducing material costs and complexity.

[0042] According to a further embodiment, the corresponding retaining elements comprise at least a roller element and a receptacle, a hook and an eyelet, a latch and an opening and / or a snap and a receptacle, wherein in particular the roller element enables a rolling movement between the base surface and the square plate.

[0043] Advantageously, the rolling motion allows for easier handling of the plate during translation compared to a sliding motion.

[0044] For example, the first and / or the second retaining element may be designed as a pin, wedge, bolt, plate, recess, receptacle, in particular slot-shaped receptacle, or through-opening.

[0045] The roller element can be designed as part of the holding device. For example, the roller element is designed as part of the holding element. The roller element comprises, for example, at least one roller, gear, or ball.

[0046] According to another embodiment, the axis of rotation is fixed on the square plate or on the base surface.

[0047] For example, the axis of rotation is determined by the arrangement of the coupling assembly. In particular, if the axis of rotation is determined at the square plate, the axis of rotation can divide the free end and the coupling section in any position of the plate. Specifically, the axis of rotation divides the plate into the free end and the coupling section, and at least in the first position of the plate.

[0048] According to another embodiment, the holding device is arranged vertically between the base surface and the square plate.

[0049] Advantageously, a storage area, for example located on the top of the board, can be used freely in the described arrangement.

[0050] According to another embodiment, the holding device is arranged in every position of the square plate between the axis of rotation and an edge of the square plate that is opposite the free end.

[0051] Advantageously, the holding device is concealed by the plate in every position due to such an arrangement.

[0052] According to a further embodiment, the coupling arrangement comprises a first coupling plate arranged in the coupling section on the underside of the square plate, and a second coupling plate arranged on the base surface, wherein the coupling plates are rotatable and slidable relative to each other, and wherein the retaining elements of the retaining device are arranged outside a fastening area of ​​the coupling sections on the top and / or bottom.

[0053] The coupling plates are each fixed to the base surface and the plate. In particular, the coupling plates can be moved relative to each other by rotation and / or translation of the plate. The coupling plates can, for example, encompass the first bearing element.

[0054] The coupling plates are connected to the substrate and the plate, particularly at fastening points. For example, the coupling plates are rectangular in shape.

[0055] In particular, a first fastening area is provided in the coupling section of the plate. For example, the first fastening area is uniformly spaced from at least two edges of the plate. In particular, the fastening area occupies a partial area of ​​the coupling section, wherein the fastening area extends over an area of ​​80% of the coupling section, in particular an area of ​​50% of the coupling section, and in particular an area of ​​30% of the coupling section.

[0056] A second fastening area can be arranged opposite the first fastening area on a top surface of the substrate, wherein the first fastening area and the second fastening area are arranged congruently above each other in at least one position.

[0057] According to another embodiment, the coupling arrangement and / or the holding device is, at least partially, recessed in the base surface and / or the plate.

[0058] Advantageously, by burying the holding device and / or the coupling arrangement in the base surface and / or the plate, a gap between the plate and the base surface can be minimized.

[0059] In particular, the coupling plates of the holding device are recessed, at least partially, into the plate and / or the base surface.

[0060] According to a further embodiment, the table arrangement further comprises at least one additional bearing element which, in a second position of the angular plate, supports the free end against the base surface extending below the plate.

[0061] Advantageously, the free end of the plate is supported in the second position, which allows the plate to be made rigid in the second position.

[0062] In particular, the at least one additional bearing element is suitable for restricting the plate in the second position along at least one degree of freedom.

[0063] The bearing element can be designed, for example, as a sleeve, knob, or hemisphere, and is made of a rubber-like or plastic-like material.

[0064] In the second position, for example, the plate is positioned completely above the base surface. In particular, the free end of the plate is completely above the base surface.

[0065] The additional bearing element can be arranged, for example, on the top of the base surface and / or on the underside of the plate. In particular, the additional bearing element is arranged at the free end between the base surface and the plate. For example, the additional bearing element is arranged in the area of ​​the free end.

[0066] According to a further embodiment, the table arrangement comprises at least one support rail, wherein the support rail is rotatably coupled to the square plate in the area of ​​the coupling section and extends towards the free end.

[0067] Advantageously, the support rail can increase the contact area between the plate and the base surface, thereby enabling a larger tilting moment to be supported.

[0068] In particular, the support rail is arranged between the base surface and the plate. The support rail can extend, at least in sections, along the length of the plate. In particular, the support rail is designed to absorb at least part of the tilting moment. In particular, the support rail increases the plate's resistance to bending.

[0069] The support rail can be rotatably mounted along a second axis of rotation. This axis of rotation is, in particular, located at one end of the support rail.

[0070] According to another embodiment, the table arrangement comprises two support rails.

[0071] Advantageously, a second support rail can absorb larger tilting moments.

[0072] For example, a first support rail is rotatably mounted on the base surface. In particular, a second support rail is fixed to the plate. For example, the first and / or second support rail can include a retaining element.

[0073] According to another embodiment, the support surface is a lower tabletop and / or the top of a base cabinet, and the plate is an upper tabletop.

[0074] According to a further embodiment, the coupling arrangement comprises a first and a second guide track and a first and a second guide element which is guided in the guide tracks, wherein the first guide track describes a straight line with a starting point and an end point, and the second guide track describes a first straight section which is arranged parallel to the first guide track, a circular section and a second straight section which runs parallel to the first guide track, wherein a center point of the circular section is located at the end point of the straight line of the first guide track.

[0075] Advantageously, translation and rotation are determined by simple means.

[0076] For example, the second guide track is arranged around the first guide track. In particular, the guide tracks form an undercut, thereby limiting the guide elements in a vertical direction. Specifically, the straight sections and segments of the first and second guide tracks allow movement along one degree of freedom.

[0077] For example, the coupling arrangement allows movement of the plate along two degrees of freedom in at least one position.

[0078] In particular, the guide elements are arranged on the plate or the base surface. Specifically, the guide tracks are arranged opposite the guide elements.

[0079] According to another embodiment, one of the guide elements is the bearing element.

[0080] For example, the guide element that is picked up by the first guide track is the bearing element.

[0081] According to another embodiment, the plate completely covers the substrate in at least one position.

[0082] Advantageously, the complete coverage of the substrate results in the most aesthetically pleasing arrangement of the plate and the substrate.

[0083] According to a second aspect, a piece of furniture is formed with a first plate and a second plate, which comprises a table arrangement according to an embodiment of the first aspect, wherein from a starting position of the plate a guided translation and a guided rotation of the plate to the base surface is carried out successively.

[0084] The piece of furniture could be, for example, a table, shelf, cabinet, sideboard, bed, kitchen island, or chair.

[0085] Other possible implementations of the invention also include combinations of features or embodiments described previously or subsequently with regard to the exemplary embodiments, even if not explicitly mentioned. In such cases, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the invention.

[0086] Further advantageous embodiments and aspects of the invention are the subject of the dependent claims and the exemplary embodiments of the invention described below. The invention is further explained below with reference to preferred embodiments and the accompanying figures. These figures show: Fig. 1: Schematic views of a first embodiment of a table arrangement; Fig. 2: a detailed view of an embodiment for a holding device, for example for use in the first embodiment of the table arrangement; Fig. 3, Fig. 4: Perspective views of a piece of furniture with one embodiment of the table arrangement; Fig. 5: Schematic top views of another embodiment of the table arrangement to illustrate the table movement; Fig. 6: a schematic top view of an embodiment of a coupling arrangement; Fig. 7: a perspective view of a second embodiment of the table arrangement; Fig. 8 and Fig. 9: Perspective views of embodiments for retaining elements for use in the table arrangement; and Fig. 10 - 13: Perspective views of another embodiment of the table arrangement with variants of holding elements.

[0087] In the figures, identical or functionally equivalent elements have been given the same reference symbols, unless otherwise indicated.

[0088] The Fig. Figure 1A shows a top view of a first embodiment of a table arrangement 100 and the Fig. Figure 1B shows a side view. The table arrangement 100 comprises a base table 10 with a top surface 1, which serves as a support surface 1 for the rectangular tabletop 2 arranged above it in a sliding and rotatable manner. In the top view of the Fig. In the position or starting position shown with solid lines, tabletop 2 partially covers the top of the support surface 1. The surface area of ​​tabletop 2 and support surface 1 can also be the same. In the starting position, the upper right corners 8 (in the orientation of the Fig. 1A and Fig. 1B) the tabletop 2 and the base surface 1 one above the other.

[0089] The tabletop 2 is rectangular and has a length L and a width B. The short sides are formed by two edges 2A, 2B and the long sides by two edges 2C, 2D. A coupling mechanism 4, only schematically indicated, allows both a displacement or translation T and a rotation R of the tabletop 2 with the - usually fixed - base 1 of the substructure 10 about an axis of rotation R, which is oriented in the Fig. 1A is perpendicular to the drawing plane, the tabletop 2, and the support surface 1. The axis of rotation R can be shifted along the translation T.

[0090] The coupling arrangement described in EP 2 804 506 B1 or DE 20 2023 105 707 U1 is particularly suitable. However, other coupling mechanisms that enable guided or unguided movements involving translation and rotation are also conceivable. Couplings via linearly movable slides with a rotary table are known, among others. For example, the table top 2 is then mounted on a rotary table that serves as a bearing element 5 (see below).

[0091] The tabletop 2' can be moved into a final position by a combination of translation T and rotation R, which is located in the Fig. 1A is indicated by a dashed line. In the end position, the tabletop 2 is rotated 90° relative to the starting position. The area 3 of the support surface 1, which is located above the support surface 1 in both the starting and end positions of the tabletop 2 and to which the coupling arrangement 4 is attached, can be referred to as coupling section 3. For example, starting from edge 2B, which is opposite the free end 2A, coupling section 3 has a coupling section length L1, and the remaining section 9 has a length L2 along the table length, where L1 + L2 = L. Usually, L2 > L1.

[0092] In the final position (dashed line), the tabletop 2, with its free end or edge 2A opposite the coupling section 3, is "floating" above the floor. In this utility model, the final position is also referred to as the "first position." The tabletop 2 is attached to the base surface 1 in the area of ​​the support surface 1 by means of a holding device 6 such that a tilting moment K about a bearing element 5 located on the axis of rotation D is compensated without support in the free section outside the coupling section 3. The bearing element 5 is, for example, a guided element of the coupling arrangement 4 on which the tabletop 2 rests and can be moved. The axis of rotation D is generally displaceable along the translational direction T, with the linear translational movement T preferably running along the angle bisector of the corner 8.The bearing element 5 can also be multi-part or planar, resulting in a bearing line or bearing surface whose extent encloses the axis of rotation D. For the sake of simplicity, in the . Fig. 1A and Fig. 1B indicates a bearing point.

[0093] To prevent the tabletop 2 from tipping over in the first position with its free end 2A, a [missing element] is required in the Fig. 1A Hatched holding device 6 or 6' is provided between the base surface 1 and the underside 2F of the table top 2 around the area occupied by the coupling device 4.

[0094] In the Fig. Figure 1B shows a side view of the longitudinal edge 2D of the tabletop 2 in the first position and the final position after rotation and movement, looking towards the table arrangement 100. The top of the tabletop is labeled 2E and the underside 2F. The holding device 6 is visible to the right of the bearing point of the bearing element 5, and an alternative embodiment 6' is visible to the left of it. The holding device 6, 6' is located on the underside 2F and comprises at least one holding element 6, 6' that prevents vertical movement (horizontal rotation about the bearing point of the tabletop) at the location of the respective holding element 6, 6'. The holding element 6, 6' exerts a constraint torque Z that counteracts the tilting moment K.

[0095] The Fig. Figure 2 shows a detailed view of an embodiment for a holding device or holding assembly 6, as described in the Fig. 1B is indicated on the right. The holding device 6 shown in the side view comprises an upper holding element 6A, which projects from the underside 2F of the table top in the manner of an L-profile and is positively engaged with a corresponding lower holding element 6B.

[0096] By moving the table slat into its final position, as shown in the Fig. 1B and Fig. As shown in Figure 2, the retaining elements 6A and 6B interlock and prevent tipping due to the weight of the tabletop section 9, which extends beyond the bearing element 5 from edge 2B. The free section 9 of the tabletop 2 therefore requires, in its orientation, Fig. 2. To the left, there is no support from below, such as a table leg or a fastening from above. The bearing element 5 and the lower retaining element 6B form the contact points.

[0097] In alternative embodiments, a retaining element 6' can be used, which serves as a bearing point and requires a coupling of the base surface 1 with the table top 2 at the location of the axis of rotation D, preventing lifting in the vertical direction. In this alternative embodiment, the coupling at the axis of rotation D exerts a constraint torque, which is a tilting torque about the position of the alternative retaining device 6'.

[0098] The Fig. 3 and Fig. Figure 4 shows perspective views of an embodiment of a piece of furniture 300, comprising a table arrangement 100 with a base 1 and a tabletop 2. The piece of furniture 300 is depicted as a corner unit, specifically as a desk.

[0099] For example, furniture piece 300 has two worktops, with one surface of the first worktop serving as a base 1. A second worktop, for example, panel 2, is arranged on the base 1 of the first panel. Panel 2 is coupled to the base 1 via a coupling arrangement 4.

[0100] One can recognize in the orientation of the Fig. 3 in the rear right corner 8, which abuts a wall corner 7, which corresponds to the coupling plate 4B integrated into the base surface 1 and into the Fig. 3 and Fig. Not visible in plate 2 is the integrated coupling plate 4A. The coupling arrangement 4 enables the plate 2 to pivot about the axis of rotation D as described previously, whereby in the Fig. 3. The plate 2 is in a position before pivoting and in the Fig. 4 the plate 2' is shown in a position after pivoting. In particular, the coupling arrangement 4 makes it possible in a corner situation, such as that found in Fig. As shown in Figure 3, the plate 2 is to be pivoted relative to the base surface 1 without moving the piece of furniture 300 out of the corner of the wall 7.

[0101] The free end 2A of plate 2' is in the Fig. In the pivoted position shown in Figure 4, the free end 2A is not supported by a foot or other aid and is arranged freely projecting from the base surface 1. If the translation T now takes place along the angle bisector in the direction of the wall corner 7, the free end 2A is supported by the bearing element 5, which is located in the Fig. 3 and Fig. 4 is not visible, recorded.

[0102] An exemplary movement sequence of plate 2 relative to the support surface 1 is shown in the Fig. 5A to 5D are shown. In the Fig. Figures 5A to 5D show an embodiment of the table arrangement 100, wherein the table arrangement 100 is located in the Fig. 5A to 5D are shown in different positions. Also in the Fig. 5A and Fig. Figure 5D shows the positions of the upper and lower retaining elements 6A and 6B, arranged between the plate 2 and the base surface 1, as well as the bearing elements 5 and 5'. The bearing elements 5 and 5' are each guided in a guide track 11 during translation T and rotation R, which will be described in more detail in a subsequent section.

[0103] Fig. Figure 5A shows the table arrangement 100 in an initial starting position. In this position, the plate 2 is positioned on the base surface 1, thus concealing it. The bearing elements 5 and 5' are located in initial positions within the guide track 11. Furthermore, the upper bearing elements 6A do not engage with the lower bearing elements 6B.

[0104] In the Fig. 5B is opposite the Fig. 5A The translation T of plate 2 takes place, which means that plate 2 no longer rests perfectly on the base surface 1. The translation T also causes an offset of the bearing elements 5 and 5' within the guide track 11.

[0105] In the Fig. 5C is, compared to the Fig. 5B the rotation R takes place along a section of the guide track 11. Due to the rotation R, the free end 2A of the plate 2' is now freely suspended. In order to move into the Fig. To reach position 5C, the rotation R was performed around the axis of rotation D, as previously described.

[0106] In the Fig. 5D was performed in comparison to the Fig. 5C in turn causes translation T, which positions plate 2' again in corner 8. In the position thus achieved for plate 2', the upper retaining elements 6A and lower retaining element 6B interlock. The weight of the free end 2A is supported by the upper and lower retaining elements 6A, 6B, as well as the bearing elements 5 and 5'. As in the Fig. As can be seen in 5D, in particular the upper and lower retaining elements 6A, 6B and the bearing element 5 form a triangular bearing arrangement 12, which secures the plate 2' against tilting.

[0107] The Fig. Figure 6 shows a top view of an embodiment of a coupling arrangement 4, which corresponds to the design of Fig. This corresponds to DE 20 2023 105 707 U1. The coupling arrangement 4 is suitable for coupling two plates that can move relative to each other, of which plate 2 is indicated. The bearing elements 5, 5' are arranged on plate 2 (indicated by dashed lines) and are guided along predetermined movements by guide tracks 13, 14. A first guide track 13 interacts with a first guide element 5, which is guided by the first guide track 13 along a straight section having a starting point A1 and an endpoint E1. The first and second guide tracks 13, 14 are arranged in the coupling plate 4B on the base surface 1, which is shown with dashed lines.

[0108] A second guide track 14 interacts with a second guide element 5' such that it can be guided along the second guide track 14 along a first straight section 21 and along a second straight section 23, both of which run parallel to the first guide track 13. It can be seen that the first guide track 13, or the straight section, runs section by section between the first and the second straight sections 21 and 23. This results in a starting point A21 and an endpoint E21 for the first straight section, as well as a starting point A22 and an endpoint E22 for the second straight section.

[0109] Due to the fixed relative position between the first and second guide elements 5, 5', the second guide element 5' can be guided along a circular segment 22 (shown with a dashed line) from the first straight segment 21 to the second straight segment 23, thereby performing the rotation R. During the rotation R, the bearing element 5 is in the end position E1, and the axis of rotation D extends through the bearing element 5.

[0110] During translation T, the bearing element 5' is moved along the straight sections 21, 23 from the initial position A21 to the final position E21. After rotation R, the bearing element 5' is at the initial position A22 and can be moved to the final position E22 by a further translation T.

[0111] The Fig. Figure 7 shows a further embodiment of the table arrangement 100 to illustrate the arrangement of the holding device 6. For this purpose, the plate 2' is in an intermediate position according to the Fig. Figure 5C shows the dashed line representing plate 2' in its end or first position. To ensure that the holding device 6 remains concealed beneath plate 2' throughout its movement, the following is shown in the Fig. 7, as a hatched area, indicates a holding device arrangement area 15 in which the holding devices of the holding device 6 can be stored. The translation T takes place along the angle bisector, so that the axis of rotation D is located at the endpoint of the first translation T, as shown in the Fig. 7 is shown.

[0112] The holding device arrangement area 15 is then bounded by a circular arc with radius B / 2 around the axis of rotation D in the direction of corner 8, a straight line perpendicular to the angle bisector to corner 8 through the axis of rotation D, the edge 2B of plate 2', the edge 2D of plate 2' and the edge 2C of plate 2' in the end position.

[0113] The Fig. 8, Fig. 9, Fig. 10 and Fig. Figure 11 shows cooperating retaining elements in various embodiments.

[0114] In the Fig. Figure 8 shows a roller bearing 16 and an insertion plate 17. The insertion plate 17 can be inserted along a gap 18 of the roller bearing 16 in an insertion direction ER, which corresponds to the translation T. The roller 19 supports the insertion plate 17 during insertion into the gap and holds it perpendicular to the insertion plate 17.

[0115] Fig. Figure 9 shows a tab 20 and a wedge 24. The tab 20 holds the wedge 24 perpendicular to the insertion direction ER after insertion in the insertion direction ER.

[0116] Fig. 10, Fig. 11, Fig. 12 to Fig. Figure 13 describes perspective views of another embodiment of the table arrangement 100 with variants of retaining elements. In this embodiment, the tabletop 2 is supported in two positions by additional support mechanisms located between a lower plate 101 and the underside 2F of the plate 2. For additional stability, in the first position, as shown in the Fig. 12 shown, support studs 25 are provided as bearing elements in the area of ​​the free end 2A.

[0117] In the second position, which is in the Fig. As shown in Figure 13, a first and a second support rail 26, 27 support the plate 2. The first support rail 26 is rotatable about a pivot axis C and can be moved into the Fig. 12 and Fig. The 13 positions shown are arranged. The second support rail 27 is fixed to the upper coupling plate 4A and serves as a holding device. A cutout is shown in the Fig. 10 is shown. The second support rail 27 has in the Fig. 10 a lateral opening 28, into which, for example, a, as in the Fig. Figure 8 shows a roller bearing 16 that can be inserted (see arrow). The roller bearing 16 is attached to the lower plate 101 in the holding device arrangement area.

[0118] Alternatively, the second support rail 28' can be designed as a U-profile, as shown in the Fig. Figure 11 shows that a suitable wedge 24' can engage in the open side of the U.

[0119] The two support rails 26, 27 increase the bearing surface in the second position of the plate 2 and increase stability. This allows thinner tabletops 2 to be used.

[0120] Although certain forms of guide elements are disclosed as guide pins in specific embodiments, alternative element forms can be implemented. For example, the piece of furniture can be designed as a chair with a rotating writing surface. The base can be designed as a chest of drawers or a cabinet, for example, for storing items. The axis of rotation does not necessarily have to be vertical. It is conceivable that the retaining elements extend, for example, as a rail along the width of the upper panel.
