Description

[0001] The invention relates to a table according to the preamble of claim 1, which comprises at least one tabletop and a tabletop extension.

[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 sliding extension piece on the table frame, which is usually stored at one end of the table beneath the tabletop. By pulling out this extension piece, the tabletop can be extended accordingly. More elaborate designs include two hinged extension pieces, whose relative movement to each other and to the tabletop allows the tabletop extension to be moved from a storage position to a position extending the table surface and back again. The guided movement of the two extension pieces ensures that the tabletop extension is raised to the level of the tabletop when in use, while remaining below the tabletop when stored.Depending on the design, the table extension is accessed either by pulling it out from underneath the tabletop or, in the case of a table with two tabletops, only when at least one of the tabletops is moved relative to the other. In either case, this ensures that the table extension is not visible when the table is in use.

[0003] The use of a table extension sometimes necessitates moving the table. Typically, the table is moved by grasping the edges of its tabletop(s). Particularly when the table extension is already in use, there is a risk that grasping at least one of its extension pieces could result in it being lifted improperly, damaging its moving parts. Even when stored, improper handling of the table extension can lead to damage or even injury to the user, for example, by pinching. In this context, designs are known that ensure proper handling when the extension is stored and allow the extension pieces to be secured when in use.

[0004] German patent DE 20 2023 101 221 U1 discloses a table with a locking element arranged such that the stacked extension parts cannot be grasped and lifted at their ends when stored. Simultaneously, the uppermost extension part in the stored position has a handle, which allows the table extension to be handled as intended.

[0005] German patent application DE 20 2019 105 098 U1 discloses a table whose base has a locking plate with at least one opening. The opening, corresponding to a pin on at least one accessory part, has a sequence of narrow and wider sections. The pin has a shaft and a thicker head, which, when the accessory part is lowered, can only be inserted through the wider sections of the opening. By shifting the accessory part, the pin can be moved relative to the locking plate so that its head is positioned behind a narrower section of the opening. The interlocking undercuts of the opening and pin prevent the accessory part from being unintentionally lifted.

[0006] It is also known to deflect a pivoting device on a first supplementary part, which is rotatably mounted on a holding device, such that the first supplementary part, which moves during a displacement of the table extension together with the guide means which moves along the direction of displacement, can be converted into a combined rotary and translational movement.

[0007] The present invention is based on the objective of further developing a generic table in such a way that its handling is further simplified and at the same time it has a high degree of safety against improper operation, in particular by means of self-locking in the operating position.

[0008] This problem is solved by a table with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

[0009] According to the invention, it is proposed that a mounting device is articulated in a coupling area of ​​the second extension part, which is rotatably mounted on at least one arm. This allows the coupling area of ​​the second extension part to pivot along a circular path segment around the arm in such a way that, during a relocation of the table extension between its storage position and its operating position, the second extension part passes a high point of the circular path located above the table surface, at which at least a portion of its coupling area is furthest from the table surface.

[0010] The second component is thus guided by the mounting device during its repositioning, being raised to its highest point and then lowered again in a combination of translational and limited rotational movement. This movement sequence involves the second component being first raised by the mounting device as described and then lowered again to assume both its operating and storage positions.

[0011] The advantage of this design is that the highest point acts as a kind of dead center, after which, particularly in conjunction with the other moving parts and movement options of the table extension, a self-locking or self-interference mechanism engages. This means that grasping and lifting the end of the second extension piece does not initiate a movement of the table extension from its storage position to its working position, or vice versa. The necessary sequence of movements can only be initiated by grasping and lifting the designated first extension piece. Since this piece rests on top of the second extension piece when in storage, the risk of injury to the person operating the table from having their hand caught is minimized.Furthermore, this ensures that none of the moving parts of the table extension can be overloaded and potentially damaged by improper use.

[0012] According to an advantageous further development of the basic inventive concept, the mounting device can have at least one bracket which has two arms and a connecting link between the arms. Alternatively, the mounting device can also have only one or more levers to achieve the intended mobility of the second supplementary part. A design as a bracket is simple and cost-effective to implement, particularly as a simple bending shape.

[0013] In this context, the invention provides a preferred embodiment of the bracket in which a bend can be arranged or formed at each of its free ends. The bends allow the bracket to be rotatably mounted in corresponding receptacles. Advantageously, the bends can extend coaxially to one another. This creates a common axis of rotation around which the bracket can pivot, at least to a limited extent. Depending on the embodiment, the bends can point away from each other or towards each other. It is also conceivable that the bends point in the same direction. The decision regarding the orientation of the bends rests with the person skilled in the art, who will determine this, for example, based on the available space.

[0014] Preferably, two bearing arrangements can be arranged on the second accessory part within the coupling area to pivot the mounting device to it. Advantageously, the bend of the bracket can be rotatably mounted on and / or in one of the bearing arrangements.

[0015] To achieve the most precise guidance and / or force transmission possible, it is considered particularly preferred that the mounting device may comprise at least two brackets. This allows the second supplementary part to be guided and articulated via the mounting device at at least two points.

[0016] Preferably, the second supplementary part can have at least one recess, allowing the mounting device to be at least partially accommodated within the recess, at least when stowed. The recess enables the most compact design possible. Without it, shallow angles between the mounting device and the second supplementary part would not be achievable, inevitably resulting in a greater overall height. The recess can be at least partially slotted. Ideally, the recess can be precisely adapted to the dimensions of the mounting device and / or the bracket(s) to minimize the amount of material that needs to be removed from the second supplementary part to form the recess. This ensures that the second supplementary part retains its high strength despite the recess.

[0017] With regard to the at least one possible bracket of the mounting device, it is provided that it can be rotatably mounted on the boom by means of a section of its web. In this way, part of the bracket can be used directly as a structural pivot axis, so that no additional component is required.

[0018] In a particularly preferred embodiment of the table according to the invention, it can have two arms. In this context, a bracket of the mounting device can be rotatably mounted on each arm. This allows for the most precise guidance possible and / or the transmission of forces, especially high forces.

[0019] Preferably, one or more of the extension arms can be arranged or configured on a console. The console can, for example, be arranged on a table base or on a frame that is movable relative to the table base. In any case, the console provides a sufficiently stable base for the extension arm to enable the necessary precision of the movements as well as the absorption and transmission of the resulting forces. In principle, the invention provides that the console(s) can be designed and arranged in such a way as to at least indirectly support the second accessory part in its stowed position. Thus, the console(s) form a support for the second accessory part, holding it at least partially in its stowed position.Since both extension parts lie on top of each other in the storage position, the console(s) can also bear a large part of the weight of the table extension and ultimately transfer it in a suitable manner to the surface on which the table is placed.

[0020] In an advantageous further development of the table according to the invention, it can have at least one spring element by which the second supplementary part is loaded, at least in its stowed position. In other words, the second supplementary part is loaded by a restoring force of the spring element such that its lifting from the console(s) is thereby supported. This support is only available until the spring element is relieved of its load by lifting the second supplementary part to such an extent that its restoring force is zero. Preferably, the spring element can be arranged on the console(s).

[0021] It is generally considered advantageous that the supplementary parts can each be movably coupled to the guide element by a double joint. This allows each supplementary part to pivot not only around one axis of symmetry of the guide element, but also simultaneously around a further axis, preferably parallel to it. In this way, greater mobility between the supplementary parts and relative to the guide element is achieved. The resulting "play" enables the necessary movements of the individual parts. In particular, this prevents the supplementary parts from jamming against each other.

[0022] The guiding element can preferably be a rod (solid material) or a tube (hollow body). Combinations of the above are, of course, also conceivable. Advantageously, the guiding element can have a round, particularly circular, cross-section. Alternatively or additionally, the guiding element can comprise a rod or tube as described above, or a combination of these as described above.

[0023] To achieve the most stable and precise movement of the guide element, it is considered advantageous within the scope of the invention if the table, in particular at least, has two spaced-apart rail elements between which at least a section of the guide element extends. In this way, the guide element can be slidably mounted at its ends on the rail elements. Alternatively, the guide element can be slidably mounted on at least one of the rail elements only in a section.

[0024] In principle, a preferred embodiment of the table according to the invention provides that the rail element(s), in particular each, may have a cam guide extending parallel to the direction of movement, in which the guide means is at least partially slidably supported. The cam guide may preferably extend in a straight line. Thus, the cam guide may also be designed as a longitudinal slot which is formed or arranged on and / or in the rail element(s).

[0025] The first extension piece can advantageously have a handle by which it can be grasped for the purpose of repositioning it. For this purpose, the handle can preferably be located on the top side of the first extension piece that faces upwards when stored, so that a person operating the table can immediately recognize and use the handle when accessing the table extension.

[0026] Depending on the design, the table extension can be arranged in and / or attached to a frame that is relatively movable relative to the table's base. Alternatively, the table extension can be arranged directly in and / or attached to the table base. The first design can be used, for example, when the table extension can be pulled out from under the tabletop at one end of the table. The second design can be used, for example, when the table has two tabletops that can be moved relative to each other, and the table extension only becomes visible when the two tabletops are moved apart.

[0027] In conjunction with the frame described above, the table according to the invention preferably has at least one locking device, by manipulation of which the relative displacement of the frame relative to the table base can either be blocked or released. This effectively prevents unintentional displacement of the table extension relative to the tabletop, particularly as a potential source of danger.

[0028] The table according to the invention offers extremely simple handling while simultaneously exhibiting a very high degree of safety against improper use. This is achieved primarily through the movement sequence enforced by the setup device, whereby the movements of the second extension part, possible in both the operating and storage positions, result in a kind of self-locking mechanism due to the force applied. In any case, the design according to the invention requires operation predetermined by the kinematics resulting from the pivot points and positions of the individual components, which ensures safe handling of the table extension at all times, without unnecessary overloading.

[0029] The invention is described below using an exemplary embodiment of the Fig. 1 to 4 explained in more detail. They show: Fig. 1 a table according to the invention in a view of its underside, Fig. 2 a first longitudinal section through the table according to the invention Fig. 1 in the folded state of its tabletop extension, Fig. 3 the longitudinal section from Fig. 2 by the table according to the invention made of Fig. 1 in the partially unfolded state of its tabletop extension as well as Fig. 4 the longitudinal section from Fig. 2 and Fig. 3 by the table according to the invention Fig. 1 in the fully extended position of its tabletop extension.

[0030] Fig. Figure 1 shows a view of the underside U of a table 1 according to the invention. The table 1 is shown reduced to the parts relevant for explaining the invention and has no table leg(s). By way of example, the table 1 comprises a single tabletop 2 and a tabletop extension 3. Of course, the table 1 can also comprise two or more tabletops 2, at least two of which are designed to be displaceable relative to each other, particularly in a geometric plane. The tabletop 2 is arranged on a table base 4, which is located below the tabletop 2. The tabletop extension 3 has a first extension part 3a and a second extension part 3b. In this example, the view focuses on the second extension part 3b, while the first extension part 3a lies on top of the second extension part 3b and is therefore concealed by it.

[0031] In the example shown here, the table extension 3 has a frame 5 which is slidably mounted on the table base 4 with respect to an extension direction B, so that the table extension 3 can be pulled out from under the table top 2 when required and then placed in front of or next to a - with reference to the illustration of Fig. 1. The left end of the table 1 can be used for this purpose. For this purpose, the frame 5 has two longitudinal beams 5a, 5b, which are each slidably mounted parallel to the extension direction B relative to a corresponding side part 4a, 4b of the table base 4. Between the two longitudinal beams 5a, 5b extend two spaced-apart crossbeams 5c, 5d, which together with the also spaced-apart longitudinal beams 5a, 5b define an area within which the two supplementary parts 3a, 3b of the table extension 3 are arranged.

[0032] Provided that the embodiment of table 1 possible within the scope of the invention does not include any of the previously described and in Fig. 1. The movable frame 5 shown in the table frame 5 can, for example, extend between the two side parts 4a, 4b of the table base 4 and be firmly connected to them.

[0033] In every possible embodiment of the table 1 according to the invention, the two supplementary parts 3a, 3b are movably connected to a guide means 6.

[0034] In this example, the guide element 6 is designed as a rod or tube. In any case, the guide element 6 shown here is slidably supported on two rail elements 7a, 7b with respect to a displacement direction V. The displacement direction V is perpendicular to a longitudinal direction X of the guide element 6. The two rail elements 7a, 7b are each arranged on one of the two crossbeams 5c, 5d.

[0035] Alternatively, and in a manner not shown in detail, only one rail element 7a, 7b can be provided, on which the guide means 6, which is also designed differently, is slidably supported with respect to the displacement direction V, which is preferably perpendicular to the longitudinal direction X of the guide means 6.

[0036] In any case, a pivoting device 8 is articulated to the first supplementary part 3a in a manner not shown in detail here, and is rotatably mounted on a holding device 9. The pivoting device 8 can be U-shaped or have a substantially U-shaped bracket, or be designed as such, in a manner not shown in detail here. As can be seen, the holding device 9 can comprise at least two pivot bearings 9a, 9b, in and / or on which the holding device 9 is movably arranged, at least partially. Preferably, the holding device 9 can be connected directly or indirectly to the frame 8 and / or the table base 4. Furthermore, a mounting device 10 is articulated to a coupling area D of the second supplementary part 3b, which in this case is rotatably mounted on two arms 11, 12. In the embodiment shown here, the mounting device 10 visibly has two arms 11, 12.

[0037] In principle, the mounting device 10 can also comprise, in a manner not shown in detail, only one bracket 11, 12 or another component fulfilling its assigned task, which can then be rotatably mounted on only one or at least one arm 11, 12.

[0038] Each bracket 11, 12 has two arms 11a, 11b; 12a, 12b and a web 11c, 12c connecting the arms 11a, 11b; 12a, 12b. A bend 11d, 11e; 12d, 12e is arranged or formed at the free ends of each arm 11a, 11b; 12a, 12b of the bracket 11, 12. In this example, the bend 11d, 11e; 12d, 12e of each bracket 11, 12 extends coaxially to each other and points away from each other. In each case, the mounting device 10 is rotatably mounted on at least one boom 13a, 14a. For this purpose, at least one bearing arrangement 15a - 15d is provided within the coupling area D of the second supplementary part 3b.

[0039] By way of example, a total of four bearing arrangements 15a-15d and two outriggers 13a, 14a are provided. The brackets 11, 12 are each rotatably mounted on one of the outriggers 13a, 14a by a section of their web 11c, 12c. Furthermore, a bend 11d, 11e; 12d, 12e of each bracket 11, 12 is rotatably mounted on and / or in one of the bearing arrangements 15a-15d. Each outrigger 13a, 14a is arranged on or formed on a bracket 13, 14, which in this case is connected to the associated longitudinal beam 5a, 5b and / or crossbeam 5c, 5d of the frame 5. Alternatively, the brackets 13, 14 can each be connected to a side panel 4a, 4b of the table base 4. The consoles 13, 14 are in any case designed and arranged in such a way that the second supplementary part 3b can at least indirectly be supported at least partially on the consoles 13, 14.

[0040] The tabletop extension 3, shown here and purely as an example, has a total of two spring elements 16, 17, by which the second supplementary part 3b, at least in its Fig. The load is applied in the position shown in Figure 1. The load is such that it supports the lifting of the second supplementary part 3b from the brackets 13, 14. For this purpose, the spring elements 16, 17 are arranged, purely by way of example, on each of the brackets 13, 14. Of course, at least one spring element 16, 17 can be attached at another suitable location, for example on one of the longitudinal beams 5a, 5b and / or crossbeams 5c, 5d of the frame 5.

[0041] Finally, a locking device 18, comprising two actuators 18a and 18b, can be identified, which is preferably provided for a frame 5 that is movable relative to the table base 4. The locking device 18 is designed such that the relative movableness of the frame 5 relative to the table base 4 can be either locked or released by manipulating it. In the embodiment of the locking device 18 shown here purely as an example, the two actuators 18a and 18b are operated accordingly to release or lock the locking device 18.

[0042] Fig. Figure 2 shows a longitudinal section through table 1 along the in Fig. 1 visible cut mark AA. This illustration shows a storage position S1 of the tabletop extension 3, in which the two extension parts 3a, 3b lie on top of each other and are located below a table surface F of the tabletop 2. The following is recognizable - with reference to the illustration of Fig. The area on the left of the second supplementary part 3b is partially supported on the brackets 13 and 14. Two circular arc segments K1 and K2, indicated by dashed lines, symbolize the maximum intended pivoting range of the pivoting device 8 and the mounting device 10, and indicate their respective orientations. The position of the mounting device 10 relative to the second supplementary part 3b makes it clear that the latter has at least one, in particular slot-shaped, recess 19, so that, at least in the storage position S1 shown here, the mounting device 10 can be received at least partially within the recess 19.

[0043] By grasping a handle arranged or formed on the first supplementary part 3a, which is not shown in detail here, the first supplementary part 3a can be lifted from its position shown here for the purpose of repositioning it. This initiates a sequence of movements, which is described by Fig. 3 will be explained in more detail.

[0044] Fig. Figure 3 is again the longitudinal section through table 1. Fig. 2 along the in Fig. 1 visible cut mark AA can be seen, whereby in contrast to Fig. 2. The table extension 3 is moved out of its storage position S1. Due to the relative mobility of the two extension parts 3a, 3b relative to each other and to the tabletop 2, the table extension 3 can be moved from the storage position S1 to a working position S2, which increases the table surface F of the tabletop 2, and back again. In the slightly shifted representation of the table extension 3, it becomes clear that its extension parts 3a, 3b are each movably coupled to the guide element 6 by a double joint 20, 21. Furthermore, it is now apparent that the rail elements 7a, 7b each have a cam guide L extending in a straight line parallel to the direction of movement V, in which the guide element 6 is at least partially supported for slidability.

[0045] The specific movement sequence now provides that the first supplementary part 3a, which moves along the direction of movement V during a relocation of the table extension 3, can be converted into a combined rotational and translational movement, as can be seen here. In this process, the swivel device 8 initially performs an upward movement (see change of orientation of Fig. 2 to Fig. 3) and then downwards again (see change of orientation from Fig. 3 to Fig. 4) directed movement with respect to the circular path section K2. Since the two extension parts 3a, 3b are movably connected to the guide means 6 and thus also to each other, the coupling area D is simultaneously pivoted around the cantilever 13a, 14a on the circular path section K2. As a result, during a relocation of the table extension 3 between its storage position S1 and its operating position S2, the second extension part 3b passes a high point T of the circular path section K2 located above the table surface F, at which at least part of its coupling area D is furthest from the table surface F. The lifting of the second extension part 3b is assisted by the spring elements 16, 17. Based on the illustration shown here in Fig. It can be seen from the 3 recognizable spring element 16 that it extends inclinedly in the now relaxed position, so that when the table top extension 3 is returned to the storage position S1, the spring elements 16, 17 are displaced from their unloaded orientation by the second supplementary part 3b against their restoring force, in particular pressed down.

[0046] Fig. Figure 4 shows the end of the previously described sequence of movements of the table extension 3, at which it has assumed its operating position S2.
