Abstract

Table assembly (1) has tabletops (3,4) which are carried by carrier arrangement of support unit (2,5). The support unit is arranged in an intermediate level between the parallel planes of tabletops. An axis of rotation for each of the tabletops is assigned at opposite end areas of the tabletops.

Description

The invention relates to a table arrangement with at least two table tops, which are each rotatably supported by means of at least one pivot bearing about at least one axis of rotation which is arranged eccentrically to a plate center of the respective table top, wherein the axes of rotation are spaced from each other, and wherein the at least two tabletops are arranged one above the other in different parallel planes.

Such a table arrangement is generally known especially in coffee tables. There, a table frame is provided which has three mutually spaced support columns, on each of which a table top is rotatably mounted eccentrically to its plate center. The table tops are arranged at different heights to each other, so that they can be rotated with partial overlap in an inner position or in a fanned outer position. In the coffee table known from the prior art, three support columns and accordingly three rotatable table tops are provided. It is also known, in addition to the table frame itself to arrange a further, stationary table top.

The object of the invention is to provide a table arrangement of the type mentioned, which allows a compact design and yet undisturbed rotational movement of the table tops.

This object is achieved in that the table tops are supported by a support assembly of a support unit, which is arranged in an intermediate plane arranged between the parallel planes of the table tops, and which is assigned at opposite end areas at least one axis of rotation of a table top. The rotational mobility of the table tops can be given over limited rotation angle, preferably between 90 ° and 360 °, or over full revolutions of 360 °. The term of rotational mobility in the sense of the invention thus includes any rotation of the table tops about a stationary spatial axis and / or about a table top rotation axis. In addition to at least one carrier arrangement, the carrier unit also comprises a stationary component such as a base, a stand, a frame, a pillar or the like.

In an embodiment of the invention it is provided that at least one table top is penetrated by a pivot bushing of the associated pivot bearing, and that a support member for the respective overlying table top is rotatably connected to the pivot bearing bushing of the pivot bearing of the underlying tabletop. The non-rotatable connection is a rigid connection, which is formed in one piece or by a rigid, detachable or non-detachable attachment. The pivot bearing bushing represents a relative to the rotatable tabletop stationary pivot bearing part, wherein the stationary arrangement is the rigid connection with corresponding support members to understand. The carrier parts themselves may be arranged stationarily to a carrier unit which rests on a substrate or else be movable relative to this carrier unit. For the latter case, however, all the carrier parts are in turn fixed to one another and thus rigidly connected to one another.

The inventive solution is a crankshaft-like arrangement of several tabletops one above the other possible, which are each arranged in different, in particular parallel horizontal planes rotatably to each other. The at least one support part preferably runs parallel to the table tops and is in each case arranged below or above a table top, so that the support parts can not obstruct the rotational mobility of the table top. The inventive solution, it is possible to arrange the table tops in a compact inner rest position completely overlapping each other and still allow for a Nachausssendrehen the table tops the full accessibility of the table top surface. In the case of more than two tabletops, the corresponding carrier parts preferably do not extend parallel to each other, but rather in an angular orientation - viewed in a plan view - with respect to each other, yet preferably each carrier part extends in a corresponding horizontal plane. The solution according to the invention is suitable for at least two tabletops and is equally suitable for three or more tabletops. In three or more table tops, the associated support members - seen in a plan view from above - preferably in different directions, that outwardly pivoted, ie fanned position of the table tops a substantially point-symmetrical arrangement of the table tops relative to a center of gravity of the entire table arrangement is achieved. The table arrangement according to the invention is particularly for the living or dining area of a house can be used, but can be provided in the same way in the office area.

Advantageously, the table tops are arranged at a parallel distance one above the other and each support part extends in a respective intermediate plane between a downwardly adjacent and an upwardly adjacent table top. Preferably, the position of the table tops in a vertical direction offset from each other at least by an amount is provided, which corresponds to a height of the respective support member. This ensures that the table tops can be rotated completely through 360 °.

In an embodiment of the invention, the pivot bearing bushing of the associated table top, in particular in the form of a mandrel, protrudes to opposite Durchdringungsseiten beyond the associated table top and is rigidly connected to the above and below the respective table top connecting support parts. This results in a rigid, crankshaft-like connection.

In a further embodiment of the invention, a lower, a table frame associated carrier part is designed as a boom. The table frame forms a previously mentioned carrier unit. The cantilever arm protrudes eccentrically to a vertical center axis or axis of gravity of the table frame to the outside. Preferably, the cantilever arm is rotatably supported to a stationary frame axis of the table frame, and on the cantilever arm, a first pivot bearing for the lower table top is arranged at a distance from the frame axis. This first pivot bearing has a rotary bearing bushing, as stated above. As a result, it is possible to prevent the tabletops from rotating in space during a rotary movement. Rather, corresponding side edges of the tabletops can be kept parallel during their rotational movement. This is when swinging out or in the table tops needed a reduced space. This embodiment is particularly suitable for the design of the table arrangement as a dining table, since in such an embodiment almost no lateral clearance is needed to bring the table assembly in different tabletop positions.

In a further embodiment of the invention, positive coupling means are provided which couple a rotational movement of the at least two tabletops with each other. This design ensures simultaneous pivoting of all table tops, even if only on a single table top a corresponding torque is applied. Preferably, the positive coupling means are designed such that the table tops are the same or opposite to each other rotatable. Preferably, the positive coupling means are designed such that a rotational movement can take place by equal angular amounts for both table tops. But it is also possible to provide the positive coupling means with a gear or a reduction gear, so that the table tops can perform different rotational movements. As a positive coupling means gear transmission can be provided which can be designed as a bevel or bevel gear. If a gear transmission is provided as the positive coupling means, an even number of gears are used in the case of counter-rotating movement of the table tops, and an odd number of gears are used in the case of the same direction of rotation.

In a further embodiment of the invention, the positive coupling means comprise an endless traction mechanism, which is deflected in the region of both axes of rotation of the table tops. As a traction drive in particular a belt, rope or chain drive can be provided. Corresponding deflection means in the region of the axes of rotation are thus preferably pulleys or pulleys or gears.

In a further embodiment of the invention, the positive coupling means are laid along a respective carrier part. The traction mechanism drive or the gear transmission thus preferably extends on the carrier part between the two axes of rotation.

In a further embodiment of the invention, the cantilever arm and / or the carrier parts are aligned in mutually parallel horizontal planes. As a result, a particularly compact construction of the table arrangement can be achieved in the vertical direction.

In a further embodiment of the invention, the mutually spaced axes of rotation to a focal axis of the table frame mirror-symmetrically the same distance. As a result, a substantially symmetrical construction of the table arrangement is made possible.

In a further embodiment of the invention, the table tops are aligned with each other by means of the forced coupling means such that a center of gravity position of the table arrangement remains essentially unchanged over an entire range of movement of the table tops. Thus, the table assembly is always in a stable balance regardless of the current position of the table tops. The table frame can therefore be designed in particular according to designerischen points of view, without having to apply support forces in particular against corresponding tilting moments of the table arrangement.

In a further embodiment of the invention, at least one table top is arranged höhenverlagerbar. This embodiment is particularly advantageous when using the table arrangement as a dining table, wherein in a pivoted-out rotational position preferably the at least two tabletops are arranged at the same height.

In a further embodiment of the invention, a drive device is provided to höhenzuverlagern the table top. Such a drive device may have a mechanical spring unit, a gas spring or the like. Of course, it is also possible to provide as drive means an electric motor or the like.

In a further embodiment of the invention, positive guidance means are provided in order to additionally displace the table top during a rotational movement. The positive guidance means may be provided in addition to a drive device or alternatively to the drive device. In the latter case, the positive guidance means serve to provide a superimposed lifting movement in the case of a manually initiated rotational movement of the at least one table top. Preferably, the positive guidance means are mechanically designed.

In a further embodiment of the invention, the support member is at least partially recessed in a recess of the above and / or underlying tabletop. As a result, it is advantageously possible to further improve the compactness of the table and also its design appearance. Because by the at least partially sinking of the support member in a recess of the overlying or complementary or alternatively in a recess of the underlying tabletop, the tabletops are arranged almost superimposed and positioned the support member largely invisible. In accordance with thick table tops, the support member can be arranged completely sunk and thus hidden invisible between the table tops.

In a further embodiment of the invention, each table top has two mutually spaced pivot bearing, and the support assembly has two parallel carrier, which each end is associated with an axis of rotation of the respective table top. As a result, the parallel carrier act as a parallelogram, the over a limited swing angle of preferably 90 ° shift the table tops between a superimposed, compact rest position and a fanned-out functional position. Due to the parallel displacement, the side edges of the tabletops maintain their parallel alignment in space during the displacement.

A table arrangement 1 according to FIGS. 1 to 5 has a table frame standing on a base, which in the illustrated embodiment has a base 2, a support column 5 arranged concentrically with the base 2 and perpendicular to the ground, and a cantilever arm 6 which abuts an upper end face of the support column 5 is fixed and projects laterally outwards radially to a central longitudinal axis of the support column 5. The extension arm 6 is rigidly connected to the support column 5. In an embodiment of the invention, not shown, the extension arm 6 is an integrally designed with the support column extension 5, which protrudes at right angles to the support column and thus radially to its central longitudinal axis to the side eccentrically to the side similar to the boom shown here.

In the illustrated embodiment, the base 2 is designed circular disk-shaped. The supporting column 5 sets in the center of the circular disk-shaped base 2, so that supporting column 5 and base 2 designed rotationally symmetrical and coaxial with each other - relative to a central longitudinal axis of the support column 5 - are arranged. The support column 5 has a cylindrical shape. The support frame thus formed carries in the manner described below, two table tops 3, 4, of which the table top 3 is a lower and the table top 4 is an upper table top. Both table tops 3, 4 are circular, wherein in the illustrated embodiment, the lower table top 3 has a slightly smaller diameter than the upper table top 4. In an embodiment, not shown, both table tops 3, 4 are identical, ie both in terms of their diameter as well in terms of their thickness. In the illustrated embodiment, both table tops 3, 4 each consist of a transparent glass plate.

Both table tops 3, 4 are each rotatably mounted eccentrically to its center. In this case, both table tops 3, 4 around mutually parallel radial planes - relative to the central longitudinal axis of the support column 5 - rotatably mounted, so that both table tops 3, 4 are rotatable in vertical alignment of the support column 5 in superimposed horizontal planes. The table top 3 is rotatably supported by a pivot bearing 8, which penetrates the table top 3. The upper table top 4 is rotatably mounted relative to a serving as a support member support arm 7, which is aligned in a arranged between the two horizontal planes of the two tabletops 3, 4 horizontal plane and extending from a rotational axis of the pivot bearing 8 parallel to the boom 6 and thereby the Center longitudinal axis of the support column 5 intersects at right angles. The support arm 7 extends beyond the central longitudinal axis of the support column 5 to rotatably support at its free end a rotary base 9 about a further axis of rotation, which carries the table top 4. The further axis of rotation of the rotary base 9 has a radial distance from the central longitudinal axis of the support column 5, which is identical to the distance of the radially opposite axis of rotation of the rotary bearing 8.

The support arm 7 is connected in the manner of a crankshaft design fixed with serving as a rotary bushing cylindrical mandrel 13 (Fig. 5) of the pivot bearing 8, wherein the mandrel 13 is aligned coaxially to the axis of rotation of the pivot bearing 8 and the tabletop 3 penetrates. The table top 3 has for this purpose a circular passage. The mandrel 13 is fixedly connected in the region of its lower end to the boom 6, so that there is a rigid connection in the manner of a crankshaft design on the boom 6, the mandrel 13 to the support arm 7.

The rotary base 9 has a disc-shaped support member which is fixedly connected to the underside of the table top 4, preferably glued. Down the rotary base 9 is associated with a bearing journal which is rotatably mounted in the support arm 7 coaxial with the axis of rotation of the table top 4. The stability of the support arm 7 is designed such that the support arm 7 can carry the weight of the table top 4, without bending against its attachment to the mandrel 13 appreciably.

In order to twist the other table top 3, 4 during a rotary motion of one of the two table tops 3, 4, the two table tops 3, 4 are associated with positive coupling means 10 to 12, which are designed in the form of a toothed gear, the gears 10 to 12 along of the support arm 7 are arranged distributed. In the illustrated embodiment (FIG. 5), a total of five toothed wheels 10 to 12 are arranged side by side in alignment, all of which are spatially integrated in the support arm 7. For this purpose, the support arm 7 is designed as a cassette-like hollow body having a lower support plate and an upper, the gears 10 to 12 overlapping lid. All gears 10 to 12 have the same dimensions and the same number of teeth, so that there is a neutral transmission or reduction ratio of 1: 1. The odd number of gears causes the two table tops 3, 4 each perform the same direction rotational movements. All gears 10 to 12 are designed as spur gears, which are aligned along the support arm 7 in a row with each other. A first end-side gear 10 is fixedly connected to a rotatable bearing part of the table top 3. The second end gear 12 is rotatably connected to the rotary base 9.

The arrangement of the table tops 2, 4 as well as the arrangement of their axes of rotation relative to the support frame of the table assembly 1 is chosen so that regardless of the rotational position of the table tops 3, 4, a center of gravity of the entire table arrangement 1 almost not changes. The center of gravity of the table assembly 1 is substantially always in the region of the central longitudinal axis of the support column 5. In Fig. 1, the compact, one above the other arranged rest position of the table tops 3, 4 shown, in which both table tops 3, 4 are each aligned concentrically to the central longitudinal axis of the support column , As soon as now one of the two table tops 3, 4 is rotated out of this position, the other table top is inevitably rotated in the same direction with the outboard gear 10 to 12. In this case, the tabletops 3, 4 inevitably change their position in space, but each mirror-symmetrical to the central longitudinal axis of the support column 5, so that they are in their fanned maximum position (Fig. 2, 4, 5) to each other in equilibrium that the center of gravity of the Table arrangement almost unchanged.

In non-illustrated embodiments of the invention, the table tops are designed differently sized and / or different contours. Alternatively or additionally, the axes of rotation of the table tops can also have different distances to a vertical axis of gravity of the table frame. It is also contemplated in other embodiments of the invention to provide a reduction or gear ratio for the positive coupling means instead of a 1: 1 transmission ratio.

In the illustrated embodiment, both table tops 3, 4 are infinitely rotatable by 360 °. But it is also possible to provide a limited to less than 360 ° pivoting mobility of the table tops. In embodiments of this type, correspondingly limited positive coupling means, such as crank or lever rod arrangements and the like, may be provided instead of endlessly effective positive-displacement transmissions.

The embodiment of FIG. 6 has a table assembly 1 a, which substantially corresponds to the previously described with reference to FIGS. 1 to 5 embodiment. Functional or identical parts of the table assembly 1 a therefore have the same reference numerals with the addition of the letter "a". With regard to structure and function of the table assembly 1 a is thus supplementary to the comments on Figs. 1 to 5 referred to avoid repetition.

Significant difference in the embodiment of FIG. 6 is that instead of a gear transmission, the positive coupling means are formed by an endless traction mechanism drive 10a to 12a. In the illustrated embodiment, a toothed belt is provided as a traction means. Alternatively it can be provided as a traction means and a chain or a cable belt. Serving as a positive coupling means Zugmitteltrieb has a first gear 10a, which is assigned to the pivot bearing 8a of the lower table top 3a. In this case, the gear 10a is rotatably connected to a rotatable bearing part of the pivot bearing 8a, so that the gear 10a is rotated together with table top 3a. The opposite gear 12a is rotatably connected to the rotary base 9a, which in turn is secured to the underside of the table top 4a. The two toothed wheels 10a, 12a are looped around by an endless toothed belt 11a, which is laid inside the support arm 7a, which is designed as a preferably two-part hollow body. In the case of the present toothed belt drive, too, both toothed wheels 10a, 12a have the same size and are designed with the same number of teeth, so that a uniform torque transmission ratio results.

The embodiment according to FIGS. 7 and 8 essentially corresponds to the previously described embodiments according to FIGS. 1 to 5 and according to FIG. 6. Functionally and / or structurally identical parts of the table arrangement 1 b are denoted by the same reference numerals with the addition of the letter " b "provided. Again, regarding the description and Revelation of the structure and function of the table assembly 1b in addition to the comments on the embodiments of FIGS. 1 to 5 and 6, respectively, to avoid repetition. The support arm 7b is provided with Zwangkopplungsmittein, which may be carried out in the manner of a gear transmission according to FIG. 5 or also in the manner of a traction mechanism drive according to FIG. The essential difference in the table arrangement 1b according to FIGS. 7 and 8 is that here a lower coffee table is provided, in which the ratios between height and diameter of the tabletops differ from the previously described embodiments. In addition, although the supporting column 5b, which projects concentrically on the circular-disk-shaped pedestal 2b, is likewise cylindrical, it is designed like a step between a lower, narrower cylindrical region and an upper, broader cylindrical region.

In the embodiment according to FIGS. 9 and 10, a table arrangement 1 c is provided, which also has two parallel horizontal planes arranged one above the other table tops 3, 4c. In this embodiment, both table tops 3c, 4c are rectangular, wherein also the lower of the two table tops 3c is dimensioned slightly smaller than the upper table top 4c. Both table tops have the same thickness. The functional principle of the rotational mobility of the two tabletops 3c, 4c corresponds to the functional principle of the embodiments described above. Significant difference from the previous embodiments is that the table frame S, Q is designed differently from the previously described embodiments. In the table arrangement 1 c according to FIGS. 9 and 10, the table frame S, Q two stable plate blocks S, which stand up at a distance and parallel to each other vertically aligned on a substrate and are rigidly interconnected by a cross member profile Q. One of the two plate blocks S (in Fig. 9, the left, in Fig. 10, the right) supports and carries the support member 7 c, which is also shaped like a plate block is and corresponds in width to the width of the plate blocks S. The carrier part 7c extends transversely between the two plate blocks S, wherein it projects beyond each plate block S flush, as can be seen with reference to FIG. The support part 7c is arranged at a distance above the upper side of the plate blocks S. The carrier part 7c is carried by a supporting mandrel of the rotary bearing 8c which is not specifically designated and serves as a pivot bushing, wherein the mandrel penetrates the lower table top 3c and is connected fixedly both to the plate block S and to the carrier part 7c. The mandrel of the pivot bearing 8c is designed so stable that it can carry the support member 7c. The opposite plate block S, which is connected via the cross member Q with the rotary bearing 8c having plate block S, serves as a support for the pivot bearing 8c having plate block S to keep the entire table assembly 1c in equilibrium. To the axis of rotation of the pivot bearing 8c, the lower table top 3c is mounted rotatably. Since the support part 7c is located at a distance from the tops of the plate blocks S larger than the thickness of the table top 3c, it is possible to completely turn the table top 3c 360 ° about its rotation axis. In the region of the opposite end of the support member 7c of the rotary base 9c is rotatably mounted, which carries the upper table top 4c analogous to the embodiments described above. The rotary base 9c is fixedly connected to the underside of the table top 4c, preferably glued thereto. In the carrier part 7c, a gear transmission or a traction mechanism drive is provided in a manner not shown as positive coupling means, which causes a coupling of the rotational movements of both table tops 3c, 4c analogously to the embodiments described above. The positive coupling means are - as in the previous embodiments - invisibly integrated in the support member 7c. It is possible that the support member 7c is recessed in the region of its underside to the storage of corresponding gears or flexible traction means for a corresponding traction mechanism, as previously described was to enable. Also in this embodiment, an end-side transmission member of the positive coupling means, in particular in each case an end-side gear, in each case rotatably connected to the respective table top 3c, 4c.

The table arrangement 1d according to FIGS. 11 to 13 differs from the previously described embodiments in that instead of two tabletops three tabletops 3d, 4d, 4'd are provided. The basic structure, as has been described with reference to the embodiments according to FIGS. 1 to 8, this does not change anything. Also in the table arrangement 1 d according to FIGS. 11 to 13 is a central, resting on a substrate, circular disc-shaped base 2d provided, from which concentrically projects a support column 5d vertically upwards. An extension arm 6d adjoins an upper end face of the support column 5d, which protrudes radially outward from the support column 5d and thus protrudes horizontally outwards and is itself connected to the support column 5d. At an outer end region of the extension arm 6d, a pivot bearing 8d is arranged around which the lower table top 3d is rotatably mounted in a lower horizontal plane. The rotary bearing 8d has analogous to the previously described rotary bearings of the embodiments according to FIGS. 1 to 10 a stable support mandrel which penetrates the tabletop 3d and which is firmly connected to an overlying support member 7d. The support part 7d is aligned (FIG. 13) in a horizontal plane located above the table top 3d and projects obliquely in a top view at an acute angle to the arm 6d below it. At the front end region of the carrier part 7d opposite to the rotary bearing 8d, a further rotary bearing 8'd is arranged, on which the middle tabletop 4d is rotatably mounted. Also, the second pivot bearing 8'd has a mandrel which penetrates the table top 4d and is fixedly connected to the support member 7d. Above the table top 4d, the mandrel is fixedly connected to a second support part 7'd which again at an acute angle to the Support member 7d, but in an overlying horizontal plane, protrudes, so that the second support member 7'd is comparable to the function of the support members 7, 7c in the examples described above. At the front end region of the carrier part 7'd remote from the rotary bearing 8'd, the rotary base 9d is rotatably mounted, on which the upper table top 4'd is mounted eccentrically to its center. The rotary base 9d is rotatably mounted analogously to the above-described rotary bases 9 to 9c on the support part 7'd. For the three tabletops 3d, 4d, 4'd, there are a total of three axes of rotation, of which a first are assigned to the rotary bearing 8d, a second to the rotary bearing 8'd and a third to the rotary base 9d. All three axes of rotation have the same distance from the central longitudinal axis of the support column 5d. The three axes of rotation are each spaced at the same circumferential angle to the central longitudinal axis to each other. The arrangement of the axes of rotation of the table tops 3d, 4d, 4'd, it is possible to keep the table arrangement 1 d at each about the same position of the tabletops 3d, 4d, 4'd in each central center of gravity in the region of the central longitudinal axis of the support column 5d. All three tabletops 3d, 4d, 4'd are connected in such a way that they transmit motion by means of positive coupling means such that a rotational movement introduced into a tabletop 3d, 4d, 4'd inevitably also causes a rotation of the other tabletops. For this purpose, in the illustrated embodiment, both in the carrier part 7d and in the support part 7'd as a positive coupling means each have a gear transmission or a traction mechanism housed. The construction of the gear transmission or traction mechanism corresponds to the previously described embodiments with the two tabletops, with the difference that an analog arrangement for the third tabletop in the second carrier part 7'd is continued. It is essential in this continuation that the second pivot bearing 8'd has both a lower gear rotatably connected to the table top 4d, which is associated with the support member 7d, as well as an upper gear rotatably connected to the lower gear, the support member 7 ' d is assigned. In the upper support part 7'd then combs a corresponding Number of gears, the end having a gear rotatably connected to the rotary base 9d. Also in the present embodiment, an odd number of gears is provided when providing gear drives as Zwangkopplungsmittel each to allow the same direction rotational movements of all three tabletops 3d, 4d, 4'd. By means of this positive coupling, it is possible to fan out or fan out the tabletops 3d, 4d, 4'd in the same direction and uniformly. In Fig. 11, the stacked rest position is provided, in which the table tops are pivoted fan-like inward. From this it can also be seen that all three tabletops 3, 4d, 4'd are designed identically to one another and thus have the same diameter and the same thicknesses. In Fig. 12 the fanned-out maximum position is shown. All three tabletops can be rotated, ie fully rotatable through 360 °.

The table arrangement 1 e according to FIG. 14 corresponds in terms of its essential construction to the two-plate embodiments described above. A difference from the preceding embodiments is that, although a central base 2e is provided, which is designed as a square, preferably square plate. The support column 5e projecting vertically upwards from the center of the base 2e, on the other hand, has a cylindrical design. The essential difference from the preceding embodiments is that the two tabletops 3e, 4e are not pivoted in their rotary motion in space, but rather remain parallel with their side edges during a rotational movement in space. In order to make this possible, the cantilever arm 6e is not rigid, but rather rotatably mounted relative to a central longitudinal axis of the base 5e. The rotational mobility is achieved in the present embodiment, characterized in that the boom 6e rotatably connected to a rotatable sleeve of the support column 5e, which in turn is rotatably mounted relative to the base 2e about the central longitudinal axis. From the cantilever arm 6e protrudes a mandrel to the top, which penetrates the lower table top 3e analogous to the embodiments described above. The mandrel is firmly connected to the boom 6e as well as to the support part 7e. In addition, a toothed wheel 16, which is connected rigidly with the extension arm 6e at the height of the axis of rotation for the table top 3e coaxially with this axis of rotation, is connected to the mandrel. Coaxial with the central longitudinal axis of the support column 5e is a further, stationary and thus fixed gear 14 is provided, which is thus rotatably held to the base 2e. The two gears 14, 16 are looped by a toothed belt 15. In the illustrated embodiment, both gears 14, 16 have the same dimensions and thus the same number of teeth, so that there is a 1: 1 torque transmission. The table top 3e is otherwise coupled by means of a positive coupling means in the form of a toothed belt drive 17 to 19 with the table top 4e in its rotational movement. This positive coupling corresponds to the embodiment of FIG. 6, wherein the gear 17 is rotatably arranged to the support member 7e and thus rotatably with the lower table top 3e. The gear 19 is rotatably connected to the rotary base 9 e, which is fixed to the underside of the upper table top 4 e. The toothed belt 18 wraps around the two gears 17 and 19.

The gear 16 is rotatably mounted about the axis of rotation of the table top 3e on the boom 6e and rotatably connected to the table top 3e. Also, the upper support member 7e associated gear 17 is non-rotatably connected to the table top 3e, so that initiated on one of the two table tops 3e, 4e rotational movement via the positive coupling of the lower gear 16 and the timing belt on the fixed gear 14, a rotational movement of the table tops 3e 4e relative to the cantilever arm 6e and the carrier part 7e, without the tabletops 3e, 4e losing the parallel orientation of their lateral edges in space during the rotational movement. Each table top is thus - seen in a plan view of the table arrangement 1e - during a corresponding rotational movement with its side edges only displaced parallel in space.

In the embodiment according to FIGS. 15 to 17, a pedestal 5f fixed on a base is provided, by means of which the entire table arrangement 1f is positioned fixed in space. The basic function of the table arrangement 1f corresponds to a table arrangement, as has been disclosed on the basis of the embodiments described above. Functionally identical components have been provided with the same reference numerals with the addition of the letter f. The essential difference in the embodiment according to FIGS. 15 to 17 is that here the support arrangement supporting the table tops 3f, 4f is not formed by individual support parts, but rather by a respective pair of parallel supports 6f, 7f. Accordingly, the parallel beams 6f, 7f are not connected to the lower table top 3f by a single but rather by two rotary bearings 8f. The pivot bearing 8f penetrate the lower table top 3f in the region of two spaced apart axes of rotation. In an analogous manner, the upper table top 4f is also supported by means of the rotary base 9f in the region of two axes of rotation arranged at the same distance from each other. The two parallel beams 7f have the same length and are held parallel to each other. Advantageously, corresponding positive coupling means are also provided in the parallel supports 7f, in order to enable a synchronous displacement of both table tops 3f, 4f analogously to the previously described embodiments. Advantageously, the lower pair of parallel beams 6f also has a positive coupling with a fixed axis of the base 5f analogous to the embodiment according to FIG. 14. But it is also possible to design the parallel support 6f, 7f not with such positive coupling means, but rather to move the movement of both table tops by manual initiation of corresponding displacement movements in both table tops. If forced coupling means are integrated in the parallel supports 6f, 7f, it is advantageous to to carry out this in the form of bevel gear drives. In particular, a shaft extending along the respective parallel support is provided, which is provided at its opposite ends with bevel gears, which in turn mesh with end bevel gears in the region of the opposite axes of rotation, which are directed with a vertical axis and thus at right angles to the shaft.

The table arrangement 1 g according to FIG. 18 is provided with a table frame 2g, 5g serving as a carrying unit, the table frame having at least two supports 2g resting vertically on a substrate and at least one support 5g connecting the supports 2g in the region of their upper ends. The basic structure of the table arrangement 1g corresponds to the construction of one of the embodiments already described above with reference to FIGS. 1 to 10. The function corresponds to the embodiments described above. The essential difference in the table arrangement 1g is that here the carrier part 7g is recessed in a recess A of the upper table top 4g. This makes it possible to arrange the table tops 3g, 4g relatively close to each other, wherein the distance between the gap between the table tops 4g, 3g gap is preferably so small that no fingers can be clamped. In the area of the recess A in a manner not shown, a finger clamp protection is provided which is designed such that on the one hand, the rotational mobility of the upper table top 4g and the support member 7g is not hindered, and that on the other in the area of the recess A pinching Fingers is avoided. The finger protection is preferably carried out in a manner not shown as a cover, which covers the cover below the support member 7g horizontally. A risk of injury is excluded.

The pivot bearing 8g penetrates the lower table top 3g. The lower table top 3g is stable by at least one support profile T ₁ on the Swivel bearing 8g supported. The rotatable together with the table top 3g part of the pivot bearing 8g is rotatably connected to the support member 7g, which is rotatably connected in the region of its opposite end face by means of a rotary base about the axis of rotation of the upper table top 4g with this. Also in the area of the upper table top 4g at least one support profile T _{2 is} provided, which reinforces the non-rotatable and secure support of the table top 4g on the rotatable part of the rotary base 9g. The recess A is provided in such a manner in the underside of the upper table top 4g that the support member 7g is completely sunk in the recess A over its height, and that the support member 7g can rotate through 360 ° relative to the table top 4g. Also, the support member 7g, as the embodiments described above, provided with a positive coupling unit, preferably in the form of a toothed belt or toothed belt drive, to allow a simultaneous and synchronous rotational movement of both table tops 3g, 4g. The function of the rotational mobility of both table tops 3g, 4g between the stacked rest position shown in FIG. 18 and a fanned-out functional position corresponds to the previously described embodiments. The tabletops 3g, 4g are preferably designed with a square base. The recess A is preferably circular in shape, with respect to their dimensions at the radius of the support member 7g, based on the defined by the rotary base 9g axis of rotation, oriented.
