Description

[0001] The present invention relates to a table, in particular a desk or kitchen work table, with a first body and a furniture element according to the preamble of claim 1.

[0002] Furniture elements such as shelves or racks, in which a support plate and a shelf guided on this plate which can be moved both rotatably and translationally, are known, for example, from JP 10318669, DE 10 2017 106 170 A1 or DE 10 2017 120 160 A1.

[0003] In particular, the support plate described in the latter publication has proven itself in practice.

[0004] Such shelves or racks often pose the challenge of protecting the items stored on them from dirt while also ensuring easy access. Furthermore, these shelves or racks must always be positioned at a distance from side walls to allow for rotation without hitting the side wall.

[0005] EP 0 577 551 A1 discloses a shelving unit with two shelves that can be moved at an angle of 45° from a corner of a furniture body. For this purpose, a guide groove oriented at an angle of 45° to the side walls of the body is provided in a base of the body for a rotary cylinder projecting downward from the shelf base. This allows the respective shelf to be moved from its initial position in the corner of the furniture body, initially linearly along the guide groove, into a rotary position, and once this rotary position is reached, the shelf can be freely rotated.

[0006] The object of the present invention is to provide a table with a furniture element consisting of at least one base plate and a body, which ensures both protection of the objects stored on or in the furniture element and good accessibility thereof.

[0007] The furniture element is also to be further developed to enable even better support of the furniture element's body on a base plate and to enable the rotation of furniture elements positioned against an interfering contour, such as a wall or in a corner. A body is a furniture component with a base and at least one closed side wall, behind which at least one storage element, such as a shelf, is arranged.

[0008] This object is achieved by a table having the features of claim 1.

[0009] The table has a furniture element with a base plate arranged on a body of the furniture element.

[0010] The bearing surfaces of the body and the base plate facing each other have respective grooves in which rolling elements are guided.

[0011] The body of the furniture element can be moved relative to the base plate from an initial position to an intermediate position and further to an opening position and back.

[0012] In the intermediate position, the body is rotated relative to the base plate in one direction and displaced in a predetermined direction. In the initial position and in the open position, the body is flush with the base plate, meaning it does not protrude beyond the base plate's dimensions.

[0013] In the event that the body in the initial position protrudes beyond the base plate in dimensions, or vice versa, the same condition (same alignment / same coverage) is restored in the opening position, only with the body rotated by 180°.

[0014] If there is more than one running groove, one of the preferably two running grooves of the base plate can be designed as a running groove open towards one edge of the base plate.

[0015] In the furniture element, the at least one running groove of the base plate is formed mirror-symmetrically to an axis of symmetry running at an oblique angle to a side edge of the base plate.

[0016] In the furniture element, at least one running groove of the bearing plate can additionally be formed mirror-symmetrically to an axis of symmetry running at an oblique angle to a side edge of the bearing plate.

[0017] In the case of such a table, the furniture element can, for example, be placed in a corner of a room consisting of two side walls positioned at an angle to one another and can be easily rotated out of this corner of the room, so that the furniture element is placed in an initial position, for example, in such a way that the furniture element is covered by side walls of the body and, in an opening position rotated by, for example, 90° or 180°, is rotated out of the corner in such a way that at least one storage level of the furniture element is freely accessible to a user.

[0018] A table with such a furniture element can, standing against a wall or in a corner of a room, be moved from a position closed by side walls of the body of the furniture element to an open position by turning it, while maintaining the same basic position.

[0019] Thus, at least a partially combined translational and rotational movement of the furniture element allows easy access to the contents of the furniture element or to the surface of the table. The proportions of translational and rotational movement in the overall movement can vary throughout the movement sequence depending on the design of the grooves.

[0020] Advantageous further developments of the invention are the subject of the subclaims.

[0021] According to an advantageous embodiment of the table according to claim 3, the axis of symmetry runs at an angle of 45° to a side edge of the base plate and / or the bearing plate.

[0022] This enables, in particular, a rotational movement of the furniture element about an axis perpendicular to the plane of the running grooves from a right-angled corner of the room, wherein the furniture element executes a rotational movement of 45° to a side edge of the base plate with at least partially simultaneous translation.

[0023] According to one embodiment, a base of the body has a recess on its side facing the base plate, in which a bearing plate is mounted, with at least one groove formed in the side of the bearing plate facing the base plate. Alternatively, the bearing plate can also be formed integrally with the base of the body.

[0024] This allows for easy attachment and, if necessary, retrofitting of a furniture element that was previously not equipped with a translational-rotation option with such a bearing plate and the components connected to it to enable such a translational-rotational movement.

[0025] According to a further design variant, the raceway grooves formed in the bearing surface of the body are designed as closed, circumferential raceway grooves and thus enable reliable guidance of the rolling elements.

[0026] Preferably, the base plate, the bearing plate, the rolling elements, and the rolling element cage form a translational-rotational bearing. Such a translational-rotational bearing is available as a kit and can, in particular, also be retrofitted into the base of a furniture element.

[0027] According to a further embodiment, the rolling elements are captively accommodated in at least one rolling element cage, which particularly facilitates the assembly of the rolling elements between the raceways.

[0028] According to a preferred embodiment, the raceways formed in the bearing plate form at least one outer raceway groove and one inner raceway groove.

[0029] According to a preferred embodiment, a third groove is formed between the outer groove and the inner groove. Such a third groove serves to perform additional functions, such as, in particular, limiting the rotation of the furniture element. In this case, such a third groove must also be formed in the base plate.

[0030] According to a further design variant, a fixing device is provided on the body of the furniture element for vertical fixing of the base plate.

[0031] According to a further design variant, the base plate has a slot into which a guide sleeve protrudes, protruding from the underside of the base facing the base plate and thus guiding the translational movement. This ensures a permanent connection between the bearing plate and the base plate, thus ensuring the functionality of the bearing.

[0032] In the table according to the invention, in particular a desk or kitchen work table, the furniture element can be moved relative to the fixed furniture body by means of the translational rotation bearing from a position of the furniture element covering the body to a position of the furniture element not completely covering the body and back.

[0033] For example, in the open position, the furniture element can be aligned perpendicularly to the stationary furniture body. A first lifting device can also be attached to the body.

[0034] In this case, the furniture element may have a second lifting device operable synchronously with the first lifting device, wherein the translational-rotational bearing of the furniture element is mounted on the first lifting device.

[0035] Preferred design variants are explained in more detail below using the attached drawings. They show: Fig. 1-7 schematic views of an embodiment of a table according to the invention, which is translationally and rotationally movable relative to a furniture body, Fig. 8-9 plan views of alternative embodiments of a track groove design and correspondingly adapted rolling element cages.

[0036] In the following description of the figures, terms such as top, bottom, left, right, front, rear, etc., refer exclusively to the exemplary representation and position of the table, body, raceway grooves, base plate, rolling elements, and the like chosen in the respective figures. These terms are not to be understood as limiting; i.e., these references may change due to different working positions or the mirror-symmetrical design, etc.

[0037] In the Fig. 1 to 7The reference number 10 designates a variant of a piece of furniture 10 with a furniture element designed as a table.

[0038] The Figures 1 to 7 show an embodiment variant of a piece of furniture 10 according to the invention designed as a table with a furniture element 12 which is movable in a translational and rotational manner relative to a furniture body 11 which is fixed or frictionally engaged on a floor of a room.

[0039] The furniture 10 is, as particularly in the Figures 1 and 5 to 7 is shown, designed as a desk furniture or kitchen island or kitchen work table or the like, with the furniture body 11 firmly placed on the floor of the room and the furniture element 12 which is movable in translation and rotation relative to this.

[0040] As in the Figures 2 , 6 and 7As shown, the furniture body 11 has a receptacle 112 in a central area of ​​a work surface 111, which serves to accommodate a first lifting device 13.

[0041] The lifting device 13, designed here as a telescopic lifting device, is accommodated in the receptacle 112 of the furniture body 11, wherein telescopic elements 131, 132, 133 can be moved upwards out of the receptacle 112.

[0042] A support plate 134 is mounted on the uppermost of the telescopic elements 133. A base plate 91 of a variant of a translational-rotational bearing 9 is attached to this support plate 134.

[0043] The furniture element 12 has, as exemplified in Figure 2 shown, has a body 121 with a worktop, to the bottom of which the bearing plate 93 of the translational-rotational bearing 9 is attached.

[0044] At one end of the body 121, a side part 122 is arranged, in particular fastened, which has a central receptacle for receiving a second lifting device 16.

[0045] The second lifting device 16 preferably corresponds in its construction to that of the first lifting device 13, i.e. it also has a first, a second and a third telescopic element 161, 162, 163.

[0046] On the lowermost, first telescopic element 161 of this lifting device 16, a foot 165 with at least two rolling elements 166 is arranged.

[0047] The side part 122 thus serves the lifting device 16 arranged thereon as a second supporting leg of the furniture element 12.

[0048] The furniture element 12 is thereby supported on the one hand by the side part 122 and the second lifting device 16 arranged thereon and by the first lifting device 13.

[0049] The lifting device 13 supports the body 121 of the furniture element 12 via the translational rotation bearing 9 accommodated therebetween.

[0050] The furniture element 12 can thus be Figure 1 shown starting position, in which the furniture element 12 covers the furniture body 11, here completely, by synchronous actuation of the lifting devices 13, 16, with which the furniture element 12 can be lifted relative to the furniture body 11, up to the position shown in Figure 5 shown opening position

[0051] In the open position, the upper side of the body 121 of the furniture element 12, which serves as the work surface, is oriented perpendicular to the work surface 111 of the furniture body 11. Other opening positions are also conceivable. Depending on the orientation and design of the translational-rotational bearing 9, the furniture element 12 can be moved by a larger or smaller angle, for example, 180°.

[0052] The arrangement of the translational-rotational bearing 9 on the support plate 134 of the first lifting device 13 makes it possible, when the furniture body 11 is located in a corner of the room, to lift the furniture element 12 from the Figure 1 shown position into the Figure 5 shown position without the furniture element 12 projecting beyond a rear edge of the furniture body 11 during the movement. This is very advantageous if the furniture body 11 is arranged against a wall or in a corner.

[0053] The Figure 2 The translational-rotational bearing 9 shown is shown in detail in the Figures 3 and 4 shown.

[0054] As in the Figures 3 and 4 As shown, the base plate 91 also has grooves 94 on its bearing surface facing the bearing plate 93 for guiding rolling elements 51, which are designed here as balls.

[0055] The rolling elements 51 are also accommodated in a rolling element cage 92 to prevent loss. The rolling element cage 92 is circular in shape with several arms extending radially outward.

[0056] A guide channel 97 is also provided centrally and diagonally to two side edges of the base plate 91 that are aligned at right angles to each other.

[0057] A guide carriage 151 is movably mounted in this guide channel 97.

[0058] The guide carriage 151 as part of a fixing device 15 has, on its upper side facing the bearing plate 93 or the body 121 of the furniture element 12, a bearing neck 152 which projects into an opening 99 in the bearing plate 93 and is preferably formed on the upper side of the guide carriage 151.

[0059] This bearing neck 152 serves as an axis for a bearing ring 157, in particular a ball bearing ring, inserted into the opening 99 of the bearing plate 93, which is preferably designed as a bore, by means of which a low-friction rotational movement of the bearing plate 93 relative to the guide carriage 151 and thus relative to the base plate 91 is made possible.

[0060] On the underside of the guide carriage 151 facing away from the bearing plate 93, a roller bearing with at least two rollers 154 arranged one behind the other in the longitudinal direction of the guide channel 97 is arranged, in particular fastened.

[0061] Each of these rollers 154 has a circumferential V-shaped groove 155 into which V-shaped webs 95 project from opposite side walls of the guide channel 97 and form running surfaces for the rollers 154.

[0062] The V-shaped grooves 155 of the rollers 154, which are guided along the V-shaped webs 95 in the guide channel 97, result in an extremely stable and consistent sequence of the translational-rotational movement of the furniture element 12.

[0063] As in Figure 8 As shown, in an alternative embodiment, a third groove 28c is formed in the base plate 21 and in the bearing plate 26 in addition to an outer groove 28a and an inner groove 28b.

[0064] Such a third groove 28c enables further functions during the translation-rotation movement of the furniture element 2, 3.

[0065] The Figure 8 A third groove 28c, which follows a section of the outer groove 28a radially further inward to the origin of the rotational movement, serves to limit the rotation of the furniture element.

[0066] To make this possible, the image shown in the middle of the three representations in Figure 8The rolling element cage 5' shown here, which is approximately square in shape with slightly radially inwardly bent sides, is formed with recesses for rolling elements 51, which are arranged in the outer corners of the rolling element cage figs 5 ` are arranged for rolling elements 51 which are movable in the outer raceway groove 28a. These rolling elements 51 are arranged on an outer circle K 1.

[0067] Approximately centrally formed in the sides of the rolling element cage 5' are receptacles for additional rolling elements 51, which can be moved in the inner raceway groove 28b. These rolling elements 51 are arranged on an inner circle K2.

[0068] The rolling element 51, which is to be guided in the third raceway groove 28c, is radially inward to one of the roller cages figs 5 ` arranged rolling elements 51. This rolling element 51 is arranged on a central circle K 3.

[0069] The symmetry axes SK 1 of the rolling element arrangement 51 on the circle K 1 are inclined by 45° to the symmetry axes SK 2 of the rolling element arrangement 51 on the circle K 2 .

[0070] As shown in the figure below, Figure 8 As can be seen, inner raceways 27a and outer raceways 27b are also formed in the bearing plate 26, as well as a further third raceway 27c, which is also formed radially further inward to the rotation origin U relative to a portion of one of the outer raceways 27b.

[0071] As can also be seen in this figure, the running grooves 27a and 27b are shaped such that they are arranged symmetrically to both a vertical axis of symmetry S 1 and a horizontal axis of symmetry S 2.

[0072] Figure 9shows further design variants for rolling element cages 5, 5" with rolling element receptacles arranged so that they are arranged accordingly on an outer circle K 1 and on an inner circle K 2.

[0073] In addition, Figure 3 a push-to-move mechanism in the form of an ejection element 14 is shown, which consists of a force accumulator 141 and a plunger 142 and is arranged in the guide channel 97 in order to eject the furniture element 12 in a direction of movement after unlocking.

[0074] The use of such a push-to-move mechanism makes it possible, in particular, to design the furniture element without an operating handle and to initiate the opening movement of the furniture element by pushing it in the opposite direction to the intended opening direction. The use of an ejection mechanism that can be activated in another way is also conceivable.

[0075] Alternatively, the furniture can also be designed as a desk furniture or kitchen island or kitchen work table or the like, without an additional second lifting device on the furniture element 12. In this case, the translationally and rotationally movable furniture part is only carried by the first lifting device arranged on the stationary furniture body. List of reference symbols
