Abstract

The furniture piece has two plates (40, 42) that are rotatable relative to each other. A supporting device has two supports (30, 32), where each of the two plates is fastened respectively at the two supports. The supporting device is arranged translative movably relative to a stationary base (10), where relative position of the supports is force-coupled together with the relative position of the supporting device to the base.

Description

The invention relates to a piece of furniture, in particular a table, with at least two mutually rotatable plates, a stationary base and a support device with at least two carriers, to each of which one of the plates is attached, wherein the relative position of the carrier to each other with the relative position of the support device to the base is positively coupled.

Corresponding tables are known for example from the company Draenert, Immenstaad, under the product name "Figaro" and "Apple". In these tables, two table tops are provided, which are mutually variable with respect to their position. This change leads to a shift of the common center of gravity of the table tops. In order not to have to make the base so large that the focus is independent of the relative position of the plates to each other tip over the base, is the common Carrying device of the table tops relative to the base variable with respect to their position, so that when a shift of the common center of gravity of the table tops relative to the table tops by means of the support device and the entirety of the tabletops is displaced relative to the base and thus held the center of gravity always approximately centrally above the base becomes.

The table with the product name "Apple" has for this purpose a support device which is designed to be pivotable about a horizontal axis in the region of the base. At the upper end of the support device, two table tops are provided, of which the first is pivotable about a vertical pivot axis relative to the second. About a mechanism of the pivoting angle of the first table top relative to the second with the pivot angle of the support device is coupled such that with increasing pivoting of the first plate relative to the second and concomitant displacement of the center of gravity outward pivoting of the support device to the base center out, whereby the resulting Position of the center of gravity of the plates relative to the base is kept approximately the same.

A disadvantage of this table is considered that a change in the position of the table tops to each other inevitably has a height adjustment of the table result. In addition, an application of this principle to a table with more than two plates is not readily possible.

The table with the product name "Figaro" has a base and an eccentrically mounted on the base support column, at the upper end of a support device is mounted in the form of a pivotable about a first vertical pivot axis boom. A first table top is firmly connected to this boom. One with the first table top congruent second table top is pivotally mounted about a second vertical pivot axis at the distal end of the cantilever. The pivotal position of the pivotable relative to the boom second table top relative to the first boom-fixed table top is coupled via a chain drive with the pivoting position of the boom relative to the support column, so that the boom in a first position in which the tabletops are superimposed, from the pillar pointing to the base to the outside and in a second position, in which the second table top is pivoted relative to the first 180 °, of the column with respect to the base facing inwards. As a result, the overall center of gravity of both plates lies approximately centrally above the base in these two positions.

As a disadvantage of this table is considered that it is readily feasible also only with two plates.

The object of the invention is to provide a generic piece of furniture available, in which an alternative method of center of gravity displacement is realized, this method should also be applicable to tables with more than two plates.

This object is achieved by a piece of furniture, in particular a table, with at least two relatively rotatable plates, a stationary base and a support device with at least two carriers, to each of which one of the plate is fixed, wherein the support device arranged translationally movable relative to the base is. In an embodiment of the invention, the relative position of the carrier is positively coupled to each other with the relative position of the support device to the base. In a further embodiment, the support device has a relative to the base movable carriage, which is connected to the carriers, wherein at least one of the carrier is designed as a pivot carrier and rotatable about a vertical pivot axis on Carriage is mounted and wherein the at least one pivot support has a perpendicular to the vertical pivot axis extending arm, which is coupled to the base via a slotted guide.

Such a piece of furniture makes it possible to counteract the displacement of the center of gravity of the plates relative to the plates in the course of changing the relative position of the plates to each other by a displacement of the support device and thus the entirety of the plates relative to the base. As a result, the focus remains approximately over a center of the base, so that a tilting of the furniture is prevented. The rotatability of the plates against each other can be realized both by the fact that all plates are pivotally mounted on the carriage about vertical pivot axes, as well as by only one or more plates, which are designed to be pivotally connected to a rotatably connected to the carriage plate.

Under the translational mobility of the support device is a Längsverfahrbarkeit the support device relative to the stationary base to understand, both along a straight line and along a curved path.

The carrying device, which comprises the carriage and the carriers connected to the carriage, is moved according to the invention in translation, while the at least one pivot carrier is moved in rotation relative to the carriage. These two relative movements are forcibly coupled to each other via the slotted guide, so that each relative position of the plates is associated with each other relative to a position of the carriage relative to the base. If one of the pivoting plates is manually pivoted relative to the carriage about the vertical pivot axis, this results in that the fixedly connected to the associated pivot support beam is also pivoted and via the slotted guide movement of the carriage relative to the Socket causes, whereby the entire support device is displaced together with the plates also opposite the base.

The base may be formed flat together with the carriage and the slotted guide, so that the height of the piece of furniture is essentially determined by the height of the support device, in particular the height of the carrier. However, the base can also be designed so that it has approximately the height of the furniture with a small spacing of the plates to the base. The carriers are preferably designed as concentric hollow tubes lying in one another, to which the plates are fastened, for example by means of adhesive bonds. The arrangement of the carrier as concealed hollow tubes leads to the visual impression of a uniform support column for the plates. However, embodiments of this invention are also included in which the main or pivot axes of the carriers are spaced apart and in which the carriers are mounted at different locations of the carriage.

The carriage is preferably guided in the base so that it can perform a linear movement. However, embodiments are also conceivable and encompassed by this invention, in which the carriage is movable relative to the base on a path of movement deviating from a linear movement, for example an arcuate path of movement.

The slotted guide preferably consists of a groove or a slot in which a guide pin engages. The groove or the slot can be provided both in the boom of the pivot carrier and socket side. In embodiments in which a plurality of plates are pivotally connected via pivot support to the base, the pivot supports preferably each have their own arms, which are coupled via separate slotted guides with the base. at In such embodiments, the operation provides that the manual pivoting movement of a first plate attached to a pivot support in the described manner via the associated slotted guide has a displacement of the carriage relative to the base result and this displacement of the carriage relative to the base on a second Swivel support associated slotted guide in response causes a pivoting movement of this second pivot support and thus the associated second pivoting plate. Embodiments with two or more movable by means of pivoting plates plates are conceivable both in furniture with exclusively movable plates as well as in those with a non-rotatably by means of a rotatable carrier coupled to the carriage plate.

In one embodiment of the invention, at least one of the carrier is rotatably connected to the carriage.

The carrier associated with this plate thus follows without additional pivotal movement of the translational movement of the carriage and requires no link guide. The support rotatably connected to the carriage can be connected both directly to the carriage and guided by a separate guide and held in a rotationally fixed position to be movable together with the carriage.

In a development of the invention, the pivot axis of the at least one pivot carrier and a main axis of at least one further carrier coincide.

Such an embodiment can be realized both with carriers designed exclusively as pivot carriers, which have a common pivot axis, and with one or more pivot carriers and a non-pivotable carrier. In embodiments, where the pivot axes or main axes coincide in this manner, the carriers can form a common support column for the plates. Embodiments are considered particularly advantageous in which the carriers are realized as concentric hollow tubes. The outer hollow tube is in such a construction preferably simultaneously the outer shell of the support column. The storage of the inner rotatable hollow tube or hollow tubes can be done for example by a radially and axially acting rolling bearing assembly between the hollow tubes.

In one embodiment of the invention, the carriage is formed by means of rolling pins relatively movable to the base, wherein the rolling pins are mounted on the carriage side by means of needle bearings.

Such a bearing allows a very accurate guidance of the carriage, which offers the advantage of little play between the relative movement of the plates on the one hand and the relative movement of the carriage to the stationary base on the other hand. In an alternative embodiment, the needle roller bearings and the rolling pins mounted by the needle roller bearings can also be provided on the base side and engage in guide grooves of the carriage.

In a further development of the invention, the slotted guide for coupling the at least one pivot carrier to the base is formed by a socket-side fixed bolt and a pivot carrier side slot in the boom, wherein the slot relative to the pivot axis of the pivot carrier has a radial direction components.

The socket-side fixed bolt is next to the path of movement of the carriage rotatably mounted on the pivot carrier spaced therefrom and designed so that it engages in the slot on the boom of the pivot carrier. To reduce the friction is on Bolt preferably an additional guide element, such as a rotatable guide roller provided. The slot can be formed as a complete opening or as a groove in the boom. If the pivot support is pivoted by a manual movement of a plate attached to the pivot support, this causes the bolt to run along the slot, thereby changing the angle between the connecting line pivot carrier axis bolt and the path of movement of the pivot carrier. This is accompanied by a movement of the carriage. For furniture with two opposite the carriage pivotable plates with two so coupled with the carriage pivot supports the pivoting movement of the first plate and thus of the first pivot support in the manner described above leads to a displacement of the carriage, which in turn a pivotal movement of the second Swivel carrier has the consequence. The displacement of the carriage changes the angle between the connecting line between the pivot axis of the pivot carrier and the bolt of the second sliding guide on the one hand and the movement path of the carriage on the other. The boom of the second pivot carrier follows this change in angle and thereby pivots the second plate attached to the second pivot carrier.

The slot in the boom of the pivot carrier has in the simplest and preferred case a related to the pivot axis of the pivot carrier radial alignment. However, deviating designs may also be expedient which, at least in a section of the oblong hole, have an alignment with a radial component and a component in the circumferential direction. By such deviating designs, the ratio of the pivotal movement of the respective pivot support for translational movement of the carriage can be adjusted.

In a further development of the invention, the slotted guide for coupling the at least one pivot carrier with the base is formed by a socket-side guide track and a pivot carrier bolt on the boom.

The base-side guide track may be formed, for example, as a groove or as a continuous slot. It preferably runs orthogonal to the movement path of the carriage, but can also run obliquely thereto. The boom-side bolt engages in this guide track, so that it is moved in the course of pivoting of the pivot carrier about its pivot axis along the guide track and thereby a moment is generated, by means of which the carriage is moved along the path of movement. There are both embodiments conceivable in which the bolt engages directly in the guide track, as well as those in which an intermediate element such as a guide roller is provided, which is inserted into the guide track and engages in the bolt. In such an embodiment with an intermediate element a particularly good storage and thus a particularly high precision and low friction losses can be realized.

In a further development of the invention, the piece of furniture has a pedestal upwardly and socket-side fixed first cover plate with a first recess for the carrier and a second cover plate lying parallel to the first cover plate covering the free areas of the first recess next to the carriers on.

This combination of two cover plates can provide complete privacy, the mechanics of the piece of furniture, in particular the slide and the boom or the or the slide guides, covered. The first recess in the base-fixed first cover plate is formed so that the support for the plates of the piece of furniture can project through and reach along the predetermined by the carriage movement path each position provided relative to the base. The second cover plate serves to cover those parts of the first recess of the first cover plate, which are just exposed in addition to the just assumed position of the carrier. In the simplest case, the cover plates are formed so that the first base-fixed cover plate above the carriage closes the base and the second cover plate unterhab the first cover plate fixed to the socket and dimensioned so that even in the respective end positions of the carriage, the first recess in the first cover is completely closed opaque.

In a refinement that is based thereon, the second cover plate is designed in one piece with a pivoting support, in particular in one piece with an extension arm of a pivoting support.

In such an embodiment, the second cover plate in the course of movement of the plates to each other and thus the movement of the carriage relative to the base together with a pivot support, in particular with the boom of a pivot support, pivots. This makes it possible to dimension the second cover plate so that it does not require an enlargement of the base.

In a further development of the invention, the second cover plate is rotatably mounted in the base and has a curved, preferably spiral, second recess through which the carriers are passed.

The second cover plate is preferably round and guided by means of rotatably mounted on the base guide rollers. The recess has a curved shape. The carriers, which are passed through this recess cause in the course of the translational movement of the carriage together with the carrier, a rotation of this second cover plate, wherein the recess extends in the region in which the carrier protrude through the recess at each position of the carriage to the base obliquely to the path of movement of the carriage and thus obliquely to the first recess in the first cover plate. Due to the mounting of the preferably round second cover plate on the base, the position of an outer edge of the second cover plate relative to the base does not change with a round design of the second cover plate, regardless of the position of the slide relative to the base. This allows the realization of a complete privacy, which has no negative impact on the minimum dimensions of the base.

various stages of swinging out of the plates of the table according to the invention according to FIG. 8, wherein on the one hand the plate position and on the other the corresponding carriage position are shown.

Fig. 1 a and 1b show a first embodiment of a table according to the invention. This has a base 10, of which in Figs. 1 a and 1 b, only an upper cover plate 12 is shown. Through a recess 12a in the upper cover plate 12, an inner and an outer support 32, 30 are guided. The outer support 30 is formed as a hollow tube and rotatably connected at its lower end with a in Figs. 1 a and 1 b, not shown carriage. The inner support 32 has a shank portion 32a not visible in FIGS. 1a and 1b and a support portion 32b adjoining it at the top. The inner support 32 is formed as a pivot support and in the region of the shaft portion 32a within the non-rotatable outer support 30 in a manner not shown by means of a known axially and radially acting rolling bearing assembly about a pivot axis 6 pivotally mounted. Both carriers 30, 32 are each assigned an oval table top 40, 42. The slightly smaller lower table top 40 is attached to the end face of the rotationally fixed support 30 by an adhesive bond. In the clear cross-sectional area of the as Hollow cylinder trained carrier 30, the table top 40 has an opening for the shaft portion 32 a of the pivot support 32. The upper table top 42 is also connected to the support portion 32b of the pivot support 32 by means of an adhesive connection. Both table tops 40, 42 are connected at their respective outer edge and thus eccentrically with the respective associated carrier 30, 32.

1 a shows a first state of the table, in which the carriage 50, not shown, and thus the two connected to the carriage 50 carrier 30, 32 in an outer end position relative to the base 10 and thus with respect to the recess 12 a of the upper Cover plate 12 are. The center of gravity of the eccentrically mounted on the rotationally fixed support 30 table top 40 is located in this outer end position of the support 30 approximately centrally above the base 10. The pivot support 32 to which the table top 42 is mounted eccentrically, in the in Fig. 1 a shown Oriented state such that the table top 42 also starting from the carrier 32 in the direction of the center of the base 10 and its center of gravity thus also lies approximately centrally above the base 10. The overall center of gravity of the two plates 40, 42 is in this state therefore approximately above the center of the base 10, so that tilting of the table is excluded.

Fig. 1 b shows a second state of the table, in which the carriage 50, not shown, together with the carriers 30, 32 relative to the state shown in Fig. 1 a along a movement path 8 in the direction 8 a to the center of the base 10 toward shifted is. In this state, the carriers 30, 32 are located approximately in the middle of the base 50. The table plate 40 connected to the rotationally fixed carrier 30 is displaced to the same extent as the carrier 30 with respect to the state of FIG. 1a and is therefore not located As a result, its center of gravity is on the edge of the base 10. The pivot support 32 is in this second state to the Swivel axis 6 pivoted by 180 °. The table plate 42 fastened to the pivot support 32 is therefore no longer disposed above the table top 40, but on the opposite side of the carrier 30, 32. The center of gravity of the pivoted table top 40 is thus also no longer centrally above the base 10, but over the edge However, since the centers of gravity of both table tops 40, 42 are in this state on opposite sides approximately equidistant from the center of the base 10, they have an overall center of gravity, which in turn lies approximately above the center of the base 10. Therefore, a tilting of the table is excluded even in this state.

In order to transfer the table from the state of FIG. 1 a to the state of FIG. 1 b, the pivotable upper table top 42 is manually pivoted about the pivot axis 6 of the pivot carrier 32. This has the effect through mechanical coupling that the carriage 50, together with the carriers 30, 32, is displaced in translation relative to the base 10. The operation of this mechanical coupling will be explained with reference to FIGS. 2 to 4.

2 and 3 show the base 10 and the carrier 30, 32, wherein for better understanding in each case some part are hidden. The base 10 has a bottom plate 18, are mounted on the two guide rails 20 for the carriage 50 parallel to each other firmly. On the bottom plate is orthogonal to the guide rails 20, a guide track 22 is provided, which is part of the slide guide for coupling the relative movement between the carriers 30, 32 on the one hand and the relative movement between the carriage 50 and the base 10 on the other. The carriage 50 has two guide devices 52 which, as shown in FIG. 3, each have two roller pins 58 mounted by means of needle bearings 56, which engage in the guide rails 20 of the base 10. Between the guide devices 52 is a base plate 54 of the carriage 50, on which the guide devices 52 are attached.

From Fig. 3 it can be seen that at the lower end of the pivot support 32, a boom 34 is provided which extends in the radial direction from the vertical pivot axis 6 of the pivot support 32 away. At the distal end of the boom 34, a bolt 36 is rotatably inserted into the boom, which engages in a bore, not shown, of an intermediate element 38. This intermediate element 38 is inserted translationally movable in the guide track 22 of the stationary base 10. The pivot support 32 is mounted within the carrier 30, which in turn is fixedly connected to the base plate 54 of the carriage 50 rotatably.

When the pivot support 32 and the table top 42 connected thereto are pivoted about the pivot axis 6, starting from the state of FIGS. 2 and 3 with respect to the support 30, the bolt 36 of the arm 34 together with the intermediate element 38 in the guide track 22, depending on the pivoting direction moved left or right. Thereby, the distance between the bolt 36 and the pivot axis of the pivot carrier 32 is shortened in a direction corresponding to the movement path 8 of the carriage 50 direction 8a, so that the carriage 50, starting from the state of Figs. 2 and 3 together with the carriers 30, 32nd and the plates 40, 42 are moved along the movement path 8 in the direction 8a. If the boom 34 has been pivoted by 90 ° relative to its starting position and the supports 30, 32 have been displaced beyond the guide track 22, a further pivoting of the table top 42 and the pivot support 32 leads to an increase in the distance between the bolt 36 and the Pivot axis 6 of the pivot support 32 in the direction 8a of the movement path 8. The carriage 50 together with the carrier 30, 32 is thereby further shifted in the direction 8a until it reaches its inner end position, in the the boom is pivoted 180 ° relative to the starting position. This inner end position corresponds to the state shown in FIG. 1 b.

Relative to the slotted guide of this embodiment, which consists of the base-side guide track 22, the pivot support arm 34 and bolt 36 and the intermediate element 38 is particularly advantageous that the transfer of the table between the states of Fig. 1 a and 1b not from the pivoting direction of Table top 42 depends.

4 shows the base 10 together with a lower cover plate 14. This lower cover plate 14 is round and mounted rotatably by means of four rollers 16 provided on the guide rails 20. The lower cover plate 14, which is arranged in the base immediately below the upper cover plate 12 shown in FIGS. 1a and 1b, also has a recess 14a, which is formed bent. As through the recess 12 a of the carriage-side rotatable carrier 30 and the pivot carrier 32 inserted therein are passed through this recess 14a.

When the carriage 50 together with the carriers 30, 32 is moved in the course of the transfer of the table from the state of Fig. 1 a in the state of Fig. 1 b in the direction 8a, starting from the state shown in Fig. 4, the rotatably mounted lower cover plate 14 is rotated clockwise. The recesses 12a, 14a of the two cover plates 12, 14 are thereby in the outer and the inner end position and the intermediate layers substantially only in that area one above the other, in which the carriers 30, 32 protrude through the cover plates 12, 14. This ensures that the carriage 50 and the slide guide of the table are always covered largely opaque.

5a and 5b show a second embodiment of a table according to the invention. This also has two carriers 130, 132 which, together with a carriage 150, not shown in FIGS. 5a and 5b, between an outer end position, shown in FIG. 5a, and an inner end position, shown in FIG. 5b, relative to one Base 110 are movable. On both supports 130, 132 is in each case a square table top 140, 142 fixed by means of adhesive bonds, wherein the support 130, 132 in turn in each case eccentrically in the edge region of the table tops 140, 142 are connected thereto. Notwithstanding the embodiment of FIGS. 1 to 4 are both carriers 130, 132 to pivot carrier, both of which can be pivoted together with the table plates 140, 142 relative to the carriage 150 and the base 110 about a pivot axis 106. FIG. 5a shows the state in which both pivot supports 130, 132 are in their outer end position. In this state, both table tops 140, 142 point in the direction of the center of the base 110, so that their center of gravity is arranged in each case approximately above the center of the base 110, whereby the risk of tilting of the table is not given. Fig. 5b shows a second state in which the pivot supports 130, 132 are in their inner end position relative to the base and in which both plates 140, 142 and the respective pivot supports 130, 132 about the common pivot axis 106 in the opposite direction by respectively 90 ° are pivoted relative to their initial position. The common center of gravity of the plates 140, 142 is in this state thereby approximately over the pivot supports 130, 132 and the center of the base, so that even in this state, the risk of tilting of the table is not given.

Fig. 6 shows the essential components of the base 110 and the pivot support 130, 132 of this second embodiment of a table according to the invention. The base 110 has a bottom plate 118 on which two guide rails 120, 121 are mounted parallel to each other. On the guide rails 120, 121 is in each case after a upwardly extending bolt 120a, 121 a provided. Inserted into the guide rails 120, 121 is a base plate 154 of the carriage 150 which is movable in the directions 108a, 108b along a travel path 108 of the carriage 150. On the base plate 154 of the carriage 150, the two pivot supports 130, 132 are rotatably mounted about the pivot axis 106. The two pivot supports 130, 132 each have a boom 134, 135, which extend radially from the respective pivot supports 130, 132 to the outside. Both arms 134, 135 each have a likewise radially extending slot 134a, 135a. Each of the socket-side bolts 120a, 121a extends through these elongated holes 134a, 135a.

If, starting from the state of FIGS. 5 a and 6, one of the table tops 140, 142 is pivoted manually about the pivot axis 106, this results in that the arm 134 or 135 of the associated pivot support 130 or 132 is also pivoted and thereby the slide 150 is displaced together with the base plate 154, the pivot supports 130, 132 and the table tops 140, 142 in the direction 108 a of the movement path 108. This in turn causes the respective other pivot support 132, 130 and the associated table top 142, 140 moves symmetrically to the manually pivoted table top 140, 142. The two tabletops are symmetrical to each other from the state of Fig. 5a in the state of Fig. 5b over. As this happens, the bolts 120a, 121a travel along the slots 134a, 135a from the distal end of the slots, as shown in Figure 6, to the proximal end of the slots after pivoting the panels and the pivot supports through 45 ° and back to the distal End of the slots after pivoting of the plates and the pivot support by 90 °.

Fig. 7 shows an alternative design of the base 110. In this alternative design, the cantilever 134 'is in the form of a circle segment executed. This ensures that the arm 134 'covers a portion of a recess 112a in a cover plate 112 of the base 110, so that the carriage 150 is always largely hidden.

8 shows a sectional view of a base 210 and a carriage 250 with three supports 230, 231, 232 of a third embodiment of a table according to the invention. As in the embodiments of FIGS. 1 to 7, the base 210 has a bottom plate 218, on which two guide rails 220 are attached to guide the carriage 250. The carriage 250 has a base plate 254, which is designed in one piece with the tubular first carrier 230 and which has guide rollers 220 on the two sides facing the guide rails 220, which engage in the guide rails 220. In the carrier 230, the second carrier 231 is inserted and mounted by means of a not shown axially and radially acting bearing 238, so that the carrier 231 about a pivot axis 206 relative to the carriage 250 is rotatable. Within the second carrier 231, the columnar third carrier 232 is inserted and mounted relative to the second carrier 231 by means of a likewise axially and radially acting bearing 239 and thus relative to the carriage 250 and the second carrier 231 also rotatable about the pivot axis 206. The second and the third carrier 231, 232 are formed in this manner as a pivot carrier. They have at the lower end in each case a directly molded and radially extending from the pivot axis 206 boom 234, 235, at the end of a bolt 236, 237 is provided. These bolts 236, 237 extend downwardly from the arms 234, 235 and respectively engage in an associated base-fixed guide track 222, 223.

This second embodiment of a table according to the invention has three circular segment-shaped table tops 240, 241, 242 of different sizes, each in the region of the center of the circle segment underlying circle are eccentrically connected to one of the carriers 230, 231, 232. The lowermost and smallest table top 240 is fixedly connected to the carriage 250 via the rotationally fixed carrier 230. The middle table top 241 and the top and the largest table top 242 are pivotally formed on the pivot support 231, 232. The mechanism for moving the two pivotable table tops 241, 242 corresponds approximately to the mechanism of the second embodiment of a table according to the invention, which is shown in FIGS. 5 to 7. The difference between the mechanics of the second and the mechanics of the third embodiment of a table according to the invention lies in the fact that in this third embodiment, the slots are formed on the base side as a guide track and the two arms 234, 235 not 90 °, but by 120 ° are pivotable.

FIGS. 9a to 9d show, for different states of the table, the relative position of the tabletops 240, 241, 242 relative to one another and the relative position of the carriage 250 with respect to the base 210.

9a shows on the left side the position of the three tabletops 240, 241, 242 in an initial state, in which the carrier 250 mounted or mounted carrier relative to the base 210 in a relative to the center of the base 210 distal end position are. In this end position, the three circular-segment-shaped table tops 240, 241, 242 are arranged one above the other. Since the table tops 240, 241, 242 are respectively eccentrically fixed to the beams 230, 231, 232 and extend in the state of Fig. 9a from the supports 230, 231, 232 toward the center of the base 210, they respectively and in common a center of gravity, which is arranged approximately above the center of the base 210. In the state of Fig. 9a, the risk of tilting of the table is thus not given. On the left side of Fig. 9a, the base 210 is shown in solid lines and the carriage 250 by dashed lines. In the illustrated initial state is the carriage 250 relative to the base 210 in its outer end position. The orientation of the carrier 230, 231, 232 is marked for clarity each with an arrow. The pivot supports 231, 232 are oriented in this first state so that the arms 234, 235 point approximately in the direction of the center point of the base 210. The provided on the arms 234, 235 bolts 236, 237 are located at the inner end of the guide tracks 222, 223rd

Starting from this initial state, the plate 242 is pivoted counterclockwise. Fig. 9b shows the state of the table after pivoting of the table top 242 about the pivot axis 206 by 45 °. In this second illustrated state, together with the table top 242, the pivot support 232 is pivoted to the extension 235 to the same extent, so that the bolt 237 in the guide track 223 is displaced outwards. This leads to a displacement of the carriage 250 together with the carriers 230, 231, 232 in the direction 208a. As a result of this displacement of the carriage 250, the pivot carrier 231 is also displaced in the direction 208a. Due to the guidance of the bolt 236 of the pivot support 231 in the guide track 222 it comes with the displacement of the carriage 250 thus also pivoting of the pivot support 231 and the table top 241 by the same angle as the pivot support 232, but in the opposite direction. The table top 240 is rotatably connected to the carriage 250 and therefore not subjected to pivotal movement. The right-hand illustration of FIG. 9b shows how the table tops 240, 241, 242 are aligned in this intermediate state. The table tops 241, 242 are pivoted relative to the table top 240 in the opposite direction by 45 °.

Fig. 9c shows a second intermediate state. The table top 242 is pivoted in this second intermediate state by 75 ° relative to the initial position of Fig. 9a. The bolts 236, 237 are above their respective outer turning point in the guide tracks 222, 223 of time, which is achieved at a pivoting angle of 60 °.

Fig. 9d shows the final state when transferring the table to its maximum state. In this state, the pivoting table tops 241, 242 are each pivoted by 120 ° relative to the initial state, so that they together with the non-pivoted table top 240 result in an approximately round overall table top. The carriage 250 together with the carriers 230, 231, 232 and the table tops 240, 241, 242 is in this final state in its inner end position. As a result, the common center of gravity of the three tabletops is approximately above the center of the base 210, so that the risk of tipping over the table is not given.
