Table with table top extension

Abstract

The table (1) comprises at least one tabletop (2a, 2b) and a tabletop extension (7), which has a first extension part (7a) and a second extension part (7b), the extension parts (7a, 7b) of which can be moved from a storage position (V1, V2) to their respective operating positions (G1, G2) and back again by means of their relative mobility relative to each other and / or relative to the tabletop (2a, 2b). A table surface (F1, F2) of the tabletop (2a, 2b) can be supplemented by extension surfaces (E1, E2) of the extension parts (7a, 7b) that can be used in the operating position (G1, G2). In their storage position (V1, V2), the extension parts (7a, 7b) have a relative arrangement to each other in which their extension surfaces (E1, E2) face each other, and in particular are at least partially adjacent to one another.The tabletop extension (7) is coupled to a transfer device (10) which is designed to move the extension parts (7a, 7b) together from their storage position (V1, V2) while maintaining their relative arrangement to each other until the second extension part (7b) reaches its operating position (G2).

Description

[0001] The invention relates to a table according to the preamble of claim 1.

[0002] To increase the usable surface area of ​​a table when needed, some tables feature a tabletop extension. In the simplest case, this consists of at least one extension piece that slides along the table's base and is usually stored at one end of the table beneath the tabletop. By pulling out the extension piece, the tabletop can be lengthened. In this way, the table surface can be supplemented by the extension piece's surface area. Further designs include two extension pieces connected by hinges, allowing them to be moved from a storage position to a position where the table surface is extended and back again.This allows the extension pieces of the tabletop extension to be moved into the plane of at least one tabletop when in use, while remaining below the tabletop surface when stored. Depending on the design, access to the tabletop extension is achieved either by pulling it out from under the tabletop or, in the case of a table with two tabletops, by revealing it only when at least one of the tabletops is moved relative to the other. In either case, this ensures that the extension pieces are not visible when the table is in use.

[0003] From DE 20 2007 006 234 U1, a table is known which comprises a tabletop and a tabletop extension. The tabletop extension has a first extension part and a second extension part, whose relative mobility to each other and / or to the tabletop allows the extension parts to be moved from a storage position to their respective working positions and back again. This allows the table surface of the tabletop to be extended accordingly by extension surfaces of the extension parts that can be used in the working position. In their storage position, the extension parts are arranged relative to each other in which their extension surfaces face each other, and in particular are at least partially overlapping.

[0004] In this design, the two extension sections of the tabletop extension are connected by a hinge and guided in such a way that their movement from their storage position to their operating position and back again is based on a combined, simultaneous movement. The first extension section is lifted by the second, with deflections on both sections ensuring that as the first section pivots, both extension sections can be moved horizontally. The end section of the second extension section furthest from the first runs onto a ramp, while the end section closest to the first is lifted by a support mechanism.

[0005] The current design of such tables offers an elegant way to extend and stow the tabletop. However, the manufacturing and installation of the necessary mechanisms are complex and costly. Furthermore, the kinematic sequence of movements of the extension components during their transfer from storage to use and back can sometimes be confusing, as manually moving one extension component causes a combined pivoting and sliding movement of the other. Therefore, using such a tabletop extension relies on several components and movements, and the latter, in particular, requires the simplest possible handling.

[0006] The present invention is therefore based on the objective of further developing a generic table in such a way that its handling is as intuitive as possible.

[0007] This problem is solved by a table having the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

[0008] According to the invention, it is proposed to couple the table extension with a transfer device. The transfer device is designed to move the extension parts together from their storage position, while maintaining their relative arrangement to one another as intended in storage, until the second extension part has reached its operating position. Thus, the extension parts, which in their storage position face each other with their extension surfaces and / or at least partially overlap, are initially moved together from their storage position as a "package" without undergoing any change in their relative arrangement to one another.

[0009] The advantage of this measure lies primarily in the simple design of the transfer mechanism, which requires no additional devices to move the two extension sections relative to each other through a specific guide when they are moved from their storage position. In fact, the transfer mechanism is reduced to simply moving the two extension sections together, while they are essentially lying on top of each other, from their storage position until the second extension section reaches its operating position. For a person using the table, this results in a sequence of movements that is quickly understandable, easy to follow, and readily executable.

[0010] According to an advantageous further development of the basic inventive concept, the second extension part can always be aligned in the same way by the transfer device, both in its storage and operating positions, as well as during its movement between these positions. This means that only the local position of the second extension part is changeable, while its inclination remains unchanged and therefore constant during its movement. If the first extension part rests at least partially on the second extension part, the foregoing also applies to the first extension part. Preferably, at least the second extension part can always be aligned parallel to the tabletop.

[0011] In a particularly preferred embodiment, the transfer device can have at least one guide unit. The guide unit has two links that are pivotally connected to both the second extension part and a base frame of the table. Advantageously, the links, together with the second extension part and at least a part of the base frame, can form a four-way articulation. This provides a simple and stable pivot connection between the components involved.

[0012] In particular, the stability with regard to the articulated guidance of the tabletop extension can be further improved by means of two such guide units, which are preferably each arranged in the area of ​​one of two opposing narrow sides of the second extension part and can therefore be spaced apart from each other.

[0013] In any case, the invention provides that the guide arms of the guide unit can advantageously be supported on the table's base frame so as to be pivotable about a first axis of rotation. Furthermore, the guide arms of the guide unit can be arranged on the second extension part so as to be pivotable about a second axis of rotation. The guide arms of the respective guide unit, which are spaced apart from one another in a direction perpendicular to the axes of rotation, can be pivotable either in a common geometric plane or in geometric planes parallel to each other.

[0014] In particular, with a view to the preferably parallel alignment of the second extension part to the at least one table top, both in storage position and in use position, as well as during its transferability between storage position and use position, the guides of the, in particular each, guide unit can have the same length.

[0015] According to a preferred embodiment of the table according to the invention, the guide arms of the guide unit extend in the direction of their respective longitudinal axes, whereby the longitudinal axes of the guide arms can always be aligned parallel to each other.

[0016] Preferably, each of the guide arms of the steering unit can have a first axle section extending in the direction of the first axis of rotation. Based on this, it is provided that this first axle section of a guide arm can be movably mounted in or on a support bracket arranged on the underframe. This design allows for a simple pivotable mounting of the respective guide arm on the underframe.

[0017] Alternatively, or preferably additionally, the guide arms of the guide unit can each have a second axial section extending in the direction of the second axis of rotation. This section can then advantageously be movably mounted in or on at least one rotary seat arranged on the second extension part. This design allows for a simple configuration for pivoting the respective guide arm on the second extension part.

[0018] According to a particularly preferred embodiment of the table according to the invention, the guide arms of the – or at least one – guide unit can each have an arm that pivots about the first axis of rotation. The respective arm is connected to its associated guide arm in a rotationally fixed manner, so that a pivoting movement of one guide arm about the first axis of rotation causes a simultaneous pivoting movement of its associated arm. Advantageously, the guide arms can each be connected to their respective arms via their axial section.

[0019] Preferably, each arm can have a free end section. These end sections are designed to connect the arms of the guide unit's linkages, at least indirectly, to one another via a coupling element. In this way, the pivoting motion of the linkages belonging to the arms thus connected is synchronized by the coupling element, so that the pivoting movement of one linkage of the guide unit can be transferred to the arm of the other linkage of the guide unit via the coupling element. The invention provides that a connecting section extending parallel to the axle section of the associated linkage can be arranged at each of the free end sections of the arms of the guide unit (or at least one of them). The respective connecting section can be rotatably mounted in or on the coupling element.

[0020] Preferably, each arm of the guide unit—or at least one—and the longitudinal axis of the linkage belonging to that arm can form an angle between themselves. The coupling element, or at least one arm of the guide unit—or at least one—can be connected, at least indirectly, to a spring element. The desired effect of the spring element, for example, supporting and / or braking, can be adjusted by the value of the possible angle formed between the longitudinal axis of the respective linkage and its associated arm. In this way, the transfer device—or at least one of its guide units—can be subjected to a load from the at least one spring element such that the relocation, preferably lifting, of the extension parts from their stowed position can be at least partially supported.Alternatively or preferably additionally, the movement, preferably lowering, of the extension parts into the operating position of the second extension part can be at least partially slowed down in this way. Furthermore, alternatively or preferably additionally, the movement, preferably raising, of the second extension part from its operating position, particularly together with the first extension part, can also be at least partially supported in this way.

[0021] In principle, the components directly connected to the respective handlebar can be separate parts. Alternatively, the first axle section belonging to a handlebar and the arm belonging to the same handlebar can each be a single, integral part of that handlebar made of a single material. More preferably, the first axle section belonging to a handlebar, the arm belonging to the same handlebar, and the connecting section arranged at its free end section can each be a single, integral part of that handlebar made of a single material. The single-piece construction of the individual parts allows for simple manufacturing. Thus, the respective handlebar can preferably consist of a single piece, with its axle section and arm being formed by appropriate bends. The same can apply to its connecting section.

[0022] According to a particularly preferred embodiment of the table according to the invention, its transfer device can have two guide units which are spaced apart from each other with respect to the direction of the parallel axes of rotation of their guide arms. All previously listed possible design features of the table according to the invention then apply accordingly to the guide arms of each of these two guide units.

[0023] Additionally, the second axle section of at least one link of a guide unit can be connected to the second axle section of a link of the other guide unit. Furthermore, the second axle sections of the two guide units can be integrally joined together in a single piece made of the same material. Preferably, this can then be a single, integrally made component comprising two links with their respective first axle sections and the arms attached thereto, and a continuous second axle section.

[0024] The design essentially provides for the first and second extension sections to be pivotally connected in a highly advantageous manner. This pivoting connection is configured such that the first extension section can be pivoted into and out of its operating position relative to the second extension section. Preferably, the second extension section is already in its operating position, allowing the first extension section to then also be moved into its operating position. Conversely, the first extension section, through its pivoting connection with the second extension section, can then be pivoted back out of its operating position, allowing it to be folded back onto the second extension section, after which both extension sections can be moved together back into their storage position.

[0025] Preferably, the first extension part can have a handle by which it can be gripped for the purpose of repositioning the tabletop extension. Alternatively, or preferably additionally, the handle can be configured such that the first extension part can be pivoted relative to the second extension part in the direction of its operating position by grasping the handle, particularly when the second extension part is already in its operating position.

[0026] According to the invention, at least one tabletop or tabletop extension can be arranged in and / or on a frame. The frame is at least partially displaceable within itself and / or relative to the base. Furthermore, at least one locking device can be provided, by manipulation of which the relative displaceability of the frame within itself and / or relative to the base can either be blocked or released.

[0027] The table according to the invention, as presented here, offers extremely intuitive handling with regard to its tabletop extension. The simultaneous relocation of the two extension sections using the transfer mechanism represents an easily understandable and readily comprehensible sequence of movements. Moreover, only a few moving components are required, which can also be appropriately dimensioned to enable long and low-wear operation.

[0028] Further embodiments of the invention become apparent in connection with the schematically illustrated and subsequently described in more detail exemplary embodiment of the invention. The figures show: Fig. 1 shows a table according to the invention in a perspective view with the tabletop extension in its stowed position; Fig. 2 shows a second state of the movable tabletop extension of the table.

[0029] Fig. 1Figure 1 shows a perspective view of a table 1 according to the invention. The possible embodiment of the table 1 shown is reduced to the parts relevant for explaining the invention and recognizably has no table leg(s). Thus, the table 1 further comprises, purely by way of example, a total of two tabletops 2a, 2b, which are movably arranged on a base 3. For this purpose, the base 3 has a frame 4 with two longitudinal beams 5, 6 running parallel to each other, each of which is telescopically extendable with respect to a direction of movement X and is therefore variable in length. For this purpose, each longitudinal beam 5, 6 can have two rail profiles 5a, 5b; 6a, 6b that are linearly displaceable relative to each other, of which, for example, a first rail profile 5a, 6a can be fixed to the base 3, while the other second rail profile 5b, 6b is guided longitudinally displaceably on the associated first rail profile 5a, 6a.Alternatively, both rail profiles 5a, 5b; 6a, 6b of each longitudinal beam 5, 6 can be arranged to be longitudinally displaceable relative to each other and to the base frame 3, so that – for example, by means of a corresponding deflection – the rail profiles 5a, 5b; 6a, 6b of a longitudinal beam 5, 6 move in opposite directions as soon as one of them is moved. In any case, in the present example, the two tabletops 2a, 2b are connected to the longitudinal beams 5, 6 in such a way that they can be moved away from each other and then back towards each other with respect to the direction of movement X.

[0030] In the present illustration, both tabletops 2a, 2b are displaced from each other with respect to the direction of movement X to such an extent that a tabletop extension 7 of the table 1, arranged in or on the base 3, is visible. The view focuses on a first extension part 7a of the tabletop extension 7, which is pivotally connected to a second extension part 7b of the tabletop extension 7 via hinge assemblies 8a, 8b. In the possible embodiment shown here, two hinge assemblies 8a, 8b are shown, purely by way of example. Due to this movable connection of the two extension parts 7a, 7b, the first extension part 7a is pivoted relative to the second extension part 7b to such an extent that – with reference to the illustration in Fig. 1 - the uppermost first extension part 7a at least partially on the - with reference to the representation in Fig. 1- the second extension part 7b located below. The arrangement of the two extension parts 7a, 7b shown here represents their respective storage positions V1, V2, in which the two tabletops 2a, 2b can be brought close together with their narrow sides facing each other with respect to the direction of movement X until the tabletop extension 7 is covered by them and thus remains hidden beneath the tabletops 2a, 2b. A handle 9 is arranged on one side of the first extension part 7a facing away from the second extension part 7b, by which the first extension part 7a can be grasped. This allows the tabletop extension 7 to be completely removed from its position in a manner described in more detail below. Fig. 1 The visible arrangement is moved outwards. In addition, the handle 9 serves to pivot the first extension part 7a relative to the second extension part 7b, as will be described in more detail later.

[0031] Figs. 2 to 5 First, show the necessary movement sequences of the tabletop extension 7 in order to remove its extension parts 7a, 7b from their respective positions. Fig. 1 visible - storage positions V1, V2 out into their respective - in Fig. 5 to shift the apparent position of use G1, G2, in which the table surfaces F1, F2 of the table surface (2a, 2b) available through the table surfaces 2a, 2b can be supplemented by extension surfaces E1, E2 of the extension parts 7a, 7b that can be used in position G1, G2; in detail:

[0032] Fig. 2 It can be seen that the table extension 7 comes with a Fig. 6The transfer device 10 is coupled to the transfer device 10, which is described in more detail below. The transfer device 10 is designed to move the two extension parts 7a, 7b together from their storage positions V1, V2, while maintaining their relative arrangement to each other, until the second extension part 7b reaches its position - in Fig. 3 The recognizable operating position G2 is reached. For this purpose, the transfer device 10 in the illustrated embodiment comprises a total of two guide units 10a, 10b, which are spaced apart from each other with respect to the direction of movement X and are each located in the area of ​​the narrow sides of the extension parts 7a, 7b facing away from each other and towards the table tops 2a, 2b.

[0033] It is evident that the two extension parts 7a and 7b are initially presented together from their respective, in Fig. 1 The storage positions V1 and V2, which were still occupied, are moved out by a pivoting movement, as in Fig. 2indicated by a white arrow. The relative arrangement of the extension parts 7a, 7b, which lie at least partially on top of each other in storage position V1, V2, was retained unchanged.

[0034] Fig. 3 Figure 1 shows a first interim result of the joint relocation of the tabletop extension 7. The two extension parts 7a and 7b have been relocated to such an extent that the second extension part 7b has already reached its operating position G2. The further pivoting movement of the tabletop extension 7 that was necessary for this is also indicated by a white arrow. In the operating position G2 of the second extension part 7b, it rests, at least partially, on a part of the frame 4, in particular on a longitudinal beam 5 of the frame 4.

[0035] Fig. 4This illustrates the path of the first extension part 7a towards its operating position G1, by lifting it from the second extension part 7b, which is already in its operating position G2, and pivoting it relative to the second extension part 7b – now in virtually the opposite direction. The necessary direction of the pivoting movement is again indicated by a white arrow.

[0036] Fig. 5 Figure 1 shows the result of the movement sequence of the tabletop extension 7, in which the first extension part 7a has now also reached its operating position G1 by continuing the previously initiated pivoting movement – ​​indicated here by a white arrow – so that both extension parts 7a and 7b are now in their respective operating positions G1 and G2. In operating position G1, the first extension part 7a now also rests, at least partially, on a part of the frame 4, in particular on a longitudinal beam 6 of the frame 4 (see Figure 1). Fig. 4Finally, the two tabletops 2a, 2b can be moved relative to each other in the direction of movement X in a manner not shown further, until they come into contact with the extension parts 7a, 7b of the tabletop extension 7 now integrated between them, in order to obtain as closed a surface as possible of the table 1, which is composed of the two table surfaces F1, F2 and the two extension surfaces E1, E2. In this representation, it becomes clear that the two extension parts 7a, 7b in their in Fig. 1The storage positions V1 and V2 shown are arranged relative to each other in which their extension surfaces E1 and E2 face each other, and in particular are at least partially overlapping. Due to their relative mobility relative to each other and / or to the tabletops 2a and 2b as described above, the extension parts 7a and 7b can be moved from their respective storage positions V1 and V2 to their respective operating positions G1 and G2, thereby extending the tabletops F1 and F2 of the tabletops 2a and 2b by the extension surfaces E1 and E2 of the extension parts 7a and 7b, which are usable in the operating positions G1 and G2 of the two extension parts 7a and 7b.

[0037] The table tops 2a, 2b and / or extension parts 7a, 7b can, for example, have centering bodies arranged on their respective narrow sides facing each other, which correspond to recesses on the narrow sides of the respective other table top 2a, 2b and / or the respective other extension part 7a, 7b, so that a force distribution and thus a cooperation of the table tops 2a, 2b and the extension parts 7a, 7b can be achieved under load.

[0038] Figs. 6 to 11 The previously described sequence of movements of the table extension 7 can be seen in a section of the table 1 through the base 3, in which the view focuses in particular on the narrow sides of the two extension parts 7a, 7b facing the first tabletop 2a and the narrow side of the second tabletop 2b behind them. In this view, the transfer device 10 is reduced to the representation of one of its two guide units 10a, 10b (see Fig. 2 ), which essentially each form a hinged quadrilateral. For a better overview, a [connection / connection] is shown between the two longitudinal beams 5, 6 in the area of ​​the - with reference to the illustration in [reference]. Figs. 1 to 5 - the left-hand guide unit 10a, extending and regularly concealed in the illustrations by the first tabletop 2a, is hidden, while the area of ​​the - with reference to the illustration in Figs. 1 to 5 - the right-hand guide unit 10a and the transverse wall 3b of the substructure 3 are visible in the background. The following description is based on the - with reference to the illustration in Figs. 1 to 5 - The same applies to the other command unit 10b located on the left side of the transfer unit 10a.

[0039] Fig. 6 This corresponds to the storage positions V1, V2 of the two extension parts 7a, 7b of the tabletop extension 7 as shown in the illustration. Fig. 1The guide unit 10a of the transfer device 10 shown here comprises two links 11, 12, each of which is articulated to both the base frame 3 and the second extension part 7b. For this purpose, each link 11, 12 is movably mounted on the base frame 3 by means of an associated support bracket 13, 14. Specifically, the links 11, 12 each have a first axle section extending in the direction of a first axis of rotation Y1, Y2 – which is not shown in detail here – and which is movably mounted in or on the associated support bracket 13, 14. In this way, the links 11, 12 are each pivotally supported on the base frame 3 about their first axis of rotation Y1, Y2. In addition, each link 11, 12 has a second axle section extending into a second axis of rotation Y3, Y4 - which is also not shown in detail here - and which is movably mounted in or on at least one rotary seat 15, 16 arranged on the second extension part 7b.Thus, the guides 11, 12 are also arranged on the second extension part 7b so that they can pivot about their second axes of rotation Y3, Y4. It is self-evident that the respective axes of rotation Y1 - Y4 are shown in the diagram. Figs. 6 to 11 Each link extends into and / or out of the respective plane of the sheet. In any case, the links 11, 12, which are spaced apart from each other with respect to a direction perpendicular to the axes of rotation Y1 - Y4, are pivotable either in a common geometric plane or in geometric planes parallel to each other. The links 11, 12, together with the second extension part 7b and at least a part of the base frame 3, form a four-bar linkage.

[0040] Each link 11, 12 also has an arm 11a, 12a that pivots about its associated first axis of rotation Y1, Y2 and is connected to the corresponding link 11, 12 in a rotationally fixed manner. The links 11, 12 are each connected to their respective arm 11a, 12a by their first axial section. Each arm 11a, 12a has a connecting section (not shown in detail here) located at a free end section of the respective arm 11a, 12a and extending parallel to the first axial section of the corresponding link 11, 12. The free end sections of the arms 11a, 12a are indirectly connected to each other by a coupling element 17, which is provided for synchronizing the pivotability of the links 11, 12 belonging to the arms 11a, 12a. For this purpose, the respective connecting section of the arms 11a, 12a is rotatably mounted in or on the coupling element 17. In the embodiment shown here, the coupling element 17 is connected to a spring element 18.Specifically, one end of the spring element 18 is attached to the coupling element 17, while the other end of the spring element 18 is fixed to the transverse wall 3a of the substructure 3, which is hidden here.

[0041] Preferably, the first axle section belonging to a link 11, 12, as well as the arm 11a, 12a belonging to the same link 11, 12 and the connecting section arranged at its free end section, can each be a single, integral part of this link 11, 12 made of a single material. In this way, the respective link 11, 12 is formed in one piece, for example as a bent form.

[0042] Fig. 7Figure 1 shows the beginning of the movement sequence required to utilize the table extension 7. As indicated by the white arrow, the two extension parts 7a and 7b were lifted together from their storage positions V1 and V2. The relative arrangement of the two extension parts 7a and 7b remains unchanged as they are pivoted together around the first axes of rotation Y1 and Y2 of the linkages 11 and 12. Due to the four-bar linkage design of the guide unit 10a of the transfer device 10, the extension parts 7a and 7b, which remain at least partially overlapping, maintain their orientation. At least the second extension part 7b can be aligned continuously parallel to the tabletops 2a and 2b. The two linkages 11 and 12, extending along their respective longitudinal axes X1 and X2, are of the same length a and b. Furthermore, the longitudinal axes X1, X2 of the control arms 11, 12 are always aligned parallel to each other.In direct comparison between . Fig. 6 and Fig. 7 It is evident that the spring element 18 is slightly shortened in the now raised state of the extension parts 7a, 7b. This is because the transfer device 10 is loaded by the spring element 18. In other words, the spring element 18 is stretched in the stowed position V1, V2 of the extension parts 7a, 7b, so that the restoring force of the spring element 18 – in the sense of a tensile force – now facilitates the pivoting movement. This means that the repositioning or lifting of the extension parts 7a, 7b from their stowed position V1, V2 can be at least partially supported by the spring element 18.

[0043] Fig. 8Figure 1 illustrates the behavior of the two extension parts 7a, 7b of the tabletop extension 7 during their further pivoting about the two first axes of rotation Y1, Y2 of the control arms 11, 12, as further indicated by a white arrow. In the position shown, the spring element 18 has reached at least approximately its shortest length, which means that its restoring force, which previously facilitated the pivoting movement, no longer acts on the tabletop extension 7. In this position, the spring element 18 and the two arms 11a, 12a extend parallel to each other. At the same time, the two extension parts 7a, 7b have exceeded their highest reachable point above the table tops 2a, 2b during their displacement, so that the respective longitudinal axis X1, X2 of the two guides 11, 12 have left their vertical orientation assumed during the course, so that the two extension parts 7a, 7b enter a lowering movement.In this position of the handlebars 11, 12, it is clearly visible that their respective longitudinal axes X1, X2 and their associated arms 11a, 12a enclose an angle W between them. The angle W can, for example, have a value of 30° to 40°.

[0044] Fig. 9 The figure shows the end of the pivoting movement of the two extension parts 7a, 7b around the respective first axes of rotation Y1, Y2 of the guides 11, 12, indicated by a white arrow. It is evident that the second extension part 7b has now reached its operating position G2, while the first extension part 7a remains unchanged, at least partially resting on it. In the operating position G2 of the second extension part 7b, it rests at least partially on the – with reference to the illustration of Fig. 10- left longitudinal beam 5. The necessary lowering of the two extension parts 7a, 7b was at least partially slowed down by the spring element 18, as can now be seen again - compared to its in Fig. 8 The recognizable condition – the more strongly elongated spring element 18 – is evident. Since the elongation of the spring element 18 occurred against its restoring force, this force is now again available to at least partially support the subsequent repositioning or lifting of the second extension part 7b from its operating position G2, especially together with the first extension part 7a.

[0045] Fig. 10The beginning of the displacement of the first extension part 7a towards its operating position G1 can be seen. For this to occur, the second extension part 7b remains in its already achieved operating position G2, while the first extension part 7a pivots relative to the second extension part 7b in the direction indicated by the white arrow. No movements of the transfer device 10 or its guide units 10a, 10b take place during this process. For clarity, only a section of the first extension part 7a is shown. The pivoting of the first extension part 7a relative to the second extension part 7b is achieved by means of the articulated connection between them via the hinge arrangements 8a, 8b, which are not shown here (see Figs. 1 to 4 ).

[0046] Fig. 11This represents the now fully usable tabletop extension 7. The first extension part 7a was recognizably pivoted further in the direction indicated by the white arrow relative to the second extension part 7b until it reached its operating position G1. In operating position G1, the first extension part 7a rests, at least partially, on the tabletop extension 7b – as shown in the illustration. Fig. 11- right longitudinal beam 6. The extension surfaces E1, E2 of the two extension parts 7a, 7b now extend in the same plane as well as in the plane of the table surfaces F1, F2 of the two table tops 2a, 2b. If the table top extension 7 is no longer needed, it can be stowed away again by reversing the previously described sequence of movements, by first pivoting the first extension part 7a out of its operating position G1 and folding it onto the second extension part 7b, whereupon both extension parts 7a, 7b are then pivoted back around the respective first axis of rotation Y1, Y2 of the guides 11, 12 until they reach their respective storage positions V1, V2 again.

[0047] The internal displacement of the longitudinal beams 5, 6, i.e., their telescoping ability, can be influenced by at least one locking device 19a, 19b arranged on the longitudinal beams 5, 6. The locking device 19a, 19b can be accordingly locked or released by means of a corresponding manipulation.

[0048] In a manner not shown in detail here, the second axle section of at least one link 11, 12 of a guide unit 10a, 10b can be connected to the second axle section of a link 11, 12 of the other guide unit 10a, 10b. Preferably, this can then be a completely single-piece component made of a single material. It is conceivable that the frame 4 is displaceable within itself, particularly by means of the two telescopic longitudinal beams 5, 6, and / or relative to the base 3. For example, the table 1 can have only a tabletop 2a, 2b and a tabletop extension 7, which can then be extended laterally below the tabletop 2a, 2b over the frame 4. The previously described sequence of movements is then carried out to move the extension parts 7a, 7b from their storage position V1, V2 to their operating position G1, G2 and back.
