Description

[0001] The invention relates to a demountable table comprising at least one table top and at least one first support element, wherein the first support element comprises at least one first connecting element for detachable connection to the table top, and wherein the table top comprises at least one second connecting element for detachable connection to the first support element or is at least connected to the second connecting element.

[0002] Outdoor events or outdoor catering often require tables that are repeatedly set up and dismantled, or put away for indoor storage during inclement weather or during the winter. Dismantling and reassembling these tables is usually very time-consuming and requires the use of tools if the tables have to be disassembled to save space. Nevertheless, most tables still require too much storage space. Therefore, folding tables are also available that can be set up and dismantled without tools and require less storage space. However, such folding tables are usually relatively simple and rather unstable, making them not particularly suitable for professional use.

[0003] WO 2007 / 143380 A2, for example, discloses a modular folding table with a foldable structure comprising a collapsible truss frame supporting a foldable tabletop and a foldable storage compartment. The folding table comprises a plurality of vertically arranged legs and a truss connected to each of the legs. The truss frame comprises a plurality of truss pairs of connecting elements, each of the truss pairs comprising first and second connecting elements. The connecting elements are pivotally connected to one another, with the first connecting element being pivotally connected to one of the legs and slidably connected to an adjacent leg. However, this truss structure has the disadvantage that folding and unfolding is relatively complicated and can therefore lead to incorrect operation and ultimately damage to the structure.

[0004] In addition, the stability of the table cannot be guaranteed due to its foldable structure, especially after frequent folding and unfolding.

[0005] DE 20 2019 106 284 U1 further discloses a detachable table comprising a base, a top, and an insertable column, wherein the base can be releasably coupled to the column by a first connecting device, and the top can be releasably coupled to the column by a second connecting device. The first connecting device comprises a tension rod extending through the column and engageable by rotation with the base or a part arranged on the base. The second connecting device comprises a bearing block extending on the column transversely to its extension, which comprises a connecting means, wherein the table top has a corresponding coupling piece with an internal or external thread.

[0006] DE 20 2016 004 748 U1 discloses another collapsible table made of plug-in elements. The table comprises a tabletop, a three-tube plug-in element, three first table legs for insertion into the three-tube plug-in element, three second table legs for insertion into the three-tube plug-in element, three tabletop plug-in wedges, and two hinges. The table can be adjusted to two different sizes.

[0007] However, the well-known collapsible tables have the disadvantage that assembly and disassembly is complicated and therefore time-consuming due to the large number of individual parts that have to be moved, the number of necessary steps and the required dexterity.

[0008] The invention is based on the object of creating a collapsible table with high stability, which can be assembled and disassembled without tools, easily and in just a few steps, and can be stored easily and in a space-saving manner.

[0009] The object is achieved according to the invention by a collapsible table of the type mentioned at the outset, in which one of the connecting elements (the first or the second) comprises a bulge and the other connecting element an indentation, wherein the indentation and the bulge can be plugged into one another in a form-fitting manner, and in that at least the first and / or the second connecting element comprises at least one first locking means for the reversible, non-positive fixing of the table top and / or the first support element. The fact that the first and second connecting elements are designed to correspond and can be plugged together in a form-fitting manner ensures a very stable and easy-to-establish connection between the table top and the first support element. The locking means can produce a non-positive connection between the first and second connecting elements, which can be released again easily and quickly.In a further advantageous embodiment of the invention, the first locking means can, for example, be a screw element (e.g., a wing screw or similar). When dismantling the table according to the invention, the connection between the tabletop and the first support element can be separated quickly and easily by releasing the locking means and simply lifting the tabletop. No tools are required for either assembling or dismantling the table. The table according to the invention can therefore be disassembled into its individual components in just a few simple steps and then easily stored in a space-saving manner. The table can be assembled just as quickly and easily, and when assembled, it is characterized by its particularly high stability.

[0010] In an advantageous embodiment of the invention, it is provided that the indentation and the bulge each have a circular cross-section, and that the first and the second connecting element comprise at least one first locking means which blocks a rotational movement of the table top. The circular cross-section ensures that the connecting elements can be inserted into one another quickly and easily when assembling the table according to the invention, wherein the orientation of the connecting elements initially plays no role. The correct orientation of the connecting elements or the table top can then be achieved by simply turning or rotating the plugged-together connecting elements, wherein the locking means enables a "locking" into place and thereby reversibly blocks any further rotational movement of the table top.

[0011] In an advantageous embodiment of the invention, it is further provided that the first locking means comprises at least two recesses, wherein one recess is provided with at least one locking means and the other recess comprises at least one depression corresponding to the locking means. In this advantageous manner, the locking means enables the locking means to "lock" into the corresponding depression when the two recesses are aligned, so that a rotational movement of the table top is effectively and reversibly blocked. The locking means can, for example, comprise at least one pin- or bolt-shaped element designed for positive engagement in the depression.

[0012] In an advantageous embodiment of the invention, it is provided that the first support element comprises a third connecting element at its free end opposite the first connecting element, so that the first support element can be connected, for example, to a foot element or another support element.

[0013] In the event that the table according to the invention comprises only one support element, it is provided in an advantageous embodiment of the invention that at least one foot element is provided, which comprises at least one fourth connecting element for detachable connection to the first support element or is at least connected to the fourth connecting element, wherein one of the connecting elements (the third or the fourth) comprises a bulge and the respective other connecting element comprises an indentation, wherein the indentation and the bulge can be inserted into one another in a form-fitting manner, and that at least the third and the fourth connecting element comprise at least one second locking means for the force-fitting fixation of the foot element and / or the first support element. The connection between the first support element and the foot element, ieThe connection between the third and fourth connecting elements is constructed in the same way as the above-described connection between the tabletop and the first support element, i.e., between the first and second connecting elements. This allows this very stable connection to be advantageously established without the need for tools, in just a few simple steps, by activating the locking means, and to be separated just as quickly and easily. In a further advantageous embodiment of the invention, the second locking means can be, for example, a screw element (e.g., a wing screw or similar).

[0014] In a further advantageous embodiment of the invention, two, three, or more support elements are provided. For example, several support elements can be connected to one another and connected to a base element and a tabletop, so that a stable one-legged table, in particular a standing table, can be constructed. Alternatively, several (e.g., three or four) support elements can be arranged next to one another and each connected to the tabletop, so that a stable multi-legged table, in particular a dining table, coffee table, office table, or conference table, can be constructed. The modular table system according to the invention thus enables the quick and uncomplicated assembly and disassembly of different table types and sizes, such as a standing table of different heights and / or a dining table with three or more legs.

[0015] In the event that the table according to the invention comprises at least one further support element, it is provided in an advantageous embodiment of the invention that at least one second support element is provided, which comprises at least one fifth connecting element for detachable connection to the first support element, wherein one of the connecting elements (the third or the fifth) comprises a bulge and the other connecting element comprises an indentation, wherein the indentation and the bulge can be inserted into one another in a form-fitting manner, and that at least the third and the fifth connecting element comprise at least one second locking means for the force-fitting fixation of the second support element. The connection between the first support element and the second support element, ie between the third and the fifth connecting element, is thus constructed in the same way as the above-described connection between the table top and the first support element, iebetween the first and second connecting elements. This allows very stable connections to be advantageously established without the need for tools, in just a few simple steps by activating the locking means, even in embodiments with two or more support elements. These connections can be separated just as quickly and easily. In a further advantageous embodiment of the invention, the second locking means can be, for example, a screw element (e.g., a wing screw or similar).

[0016] The second support element can advantageously comprise a sixth connecting element at its free end opposite the fifth connecting element, so that the second support element can be connected, for example, to a foot element or another support element.

[0017] If the table according to the invention comprises two support elements, at least one foot element can be provided, which comprises at least a fourth connecting element for detachable connection to the second support element or is at least connected to the fourth connecting element, wherein one of the connecting elements (the fourth or the sixth) comprises a bulge and the other connecting element comprises an indentation, wherein the indentation and the bulge can be inserted into one another in a form-fitting manner, and that at least the fourth and the sixth connecting element comprise at least one third locking means for the force-fitting fixation of the foot element and / or the second support element. The connection between the second support element and the foot element, ie between the sixth and fourth connecting elements, is thus constructed in the same way as the above-described connection between the table top and the first support element, iebetween the first and second connecting elements. This allows this very stable connection to be established in a tool-free manner, with just a few simple steps, by activating the locking means, and to be separated just as quickly and easily. In a further advantageous embodiment of the invention, the third locking means can be, for example, a screw element (e.g., a wing screw or similar).

[0018] In a further advantageous embodiment of the invention, it is provided that the indentation and the bulge each have a circular cross-section, and that the third, fourth, fifth and / or sixth connecting element comprise at least one second and / or third locking means which blocks a rotational movement of the base element and / or the second support element. The circular cross-section ensures that the connecting elements can be inserted into one another quickly and easily when assembling the table according to the invention, wherein the orientation of the connecting elements initially plays no role. The correct orientation of the connecting elements or the base element can then be achieved by simply turning or rotating the plugged-together connecting elements, wherein the locking means enables a "locking" and thereby reversibly blocks any further rotational movement of the table top.

[0019] The second and / or third locking means can comprise at least two recesses, wherein one recess is provided with at least one locking means and the other recess comprises at least one depression corresponding to the locking means. In this advantageous manner, the locking means enables the locking means to "lock" into the corresponding depression when the two recesses are aligned, so that a rotational movement of the base element or a support element is effectively and reversibly blocked. The locking means can, for example, comprise at least one pin- or bolt-shaped element designed for positive engagement in the depression.

[0020] The tabletop of the table according to the invention can comprise the second connecting element or at least be connected to the second connecting element, for example via a support element. An exemplary support element, which can be, for example, a round, polygonal, or square metal plate, is firmly connected to the second connecting element and comprises at least one fastening means for attachment to the tabletop. The support element can, for example, be screwed to the tabletop. Using such a support element, the table according to the invention can be variably equipped with different tabletops made of different materials and in numerous sizes and shapes.

[0021] The invention is explained in more detail below with reference to the figures and the following description.

[0022] It shows Fig. 1 a perspective view of an exemplary embodiment of a connecting element (first connecting element); Fig. 2 a perspective view of an exemplary embodiment of a support element with connecting element (second connecting element); Fig. 3 a perspective view of an exemplary embodiment of a support element with a foot element; Fig. 4 a perspective view of an exemplary embodiment of a table according to the invention with base element and support element (without table top); Fig. 5 an exemplary embodiment of a connecting element (first connecting element); a) Side view b) Top view c) Longitudinal section Fig. 6 an exemplary embodiment of a connecting element (second connecting element); a) Top view b) Longitudinal section (section plane AA) Fig. 7 an exemplary embodiment of a connecting element (third connecting element); a) Top view b) Side view

[0023] Fig. Figure 1 shows an exemplary embodiment of a first connecting element 1, which can, for example, be part of a support element of a table according to the invention. The first connecting element 1 comprises a recess 2 having a circular cross-section and a groove-shaped cutout 3, which is provided at its lower end with a pin- or bolt-shaped element 4. The bottom 5 of the recess 2 is pierced by a through-bore 6. The recess 2 further has a threaded bore 7 through which a screw 8 can be inserted into the interior of the recess 2. The Fig. 2 can be inserted or inserted in a form-fitting manner. For this purpose, the second connecting element 10 comprises a bulge 12 having a circular cross-section and a groove-shaped recess 13 having a depression 14 at its end facing a support element 17. The bulge 12 is cylindrical and comprises two sections 15, 16 with different outer diameters. The section 16 arranged at the free end of the bulge 12 has a smaller outer diameter than the section 15. The section 15 of the bulge 12 is firmly connected to the rectangular support element 17, to which a table top can be attached. In the exemplary embodiment shown here, the support element 17 is a flat metal plate.To create a stable connection between the two connecting elements 1, 10, the bulge 12 of the connecting element 10 can be inserted or plugged into the indentation 2 of the connecting element 1 in a form-fitting manner. The section 15 of the bulge 12 fits into the indentation 2 and the section 16 of the bulge 12 fits into the bore 6 in a form-fitting manner. In this way, a very stable connection is created between the two connecting elements 1 and 10. Due to the circular cross-sections of the bulge 12 and the indentation 2, these can initially be plugged together in any orientation. By turning one of the two connecting elements 1, 10 or one of the parts connected to it (e.g. table top or support element), the two recesses 3 and 13 can then be brought into line so that the pin- or bolt-shaped element 4 can snap into the recess 14. The pin- or bolt-shaped element 4 therefore actsThe pin-shaped element 4, in combination with the recess 14, practically acts as a locking means that blocks rotational movement of the second connecting element 10 and thus of a table top attached thereto. The pin-shaped or pin-shaped element 4 serves as a latching means that engages in the corresponding recess 14. By turning the screw 8 into the interior of the recess 2 until it stops against the section 15 of the bulge 12, a non-positive connection can advantageously be established between the two connecting elements 1, 10. The screw 8 serves as the first locking means for the reversible, non-positive fixation of the second connecting element 10 and thus of a table top attached thereto.

[0024] Fig. 3 shows an exemplary embodiment of a support element 20, which is connected at its lower end to a foot element 21. The support element 20 is further connected at its upper free end to the first connecting element 1 according to Fig. 1. At the opposite end, the support element 20 has a third connecting element 22, via which the foot element 21 is attached to the support element 20. As can be seen from Fig. 4, the second connecting element 10 can be arranged according to Fig. 2 as above with regard to the Fig. 1 and Fig. 2, can be connected in a form-fitting and force-fitting manner to the first connecting element 1 and thus also to the support element 20. In this illustration, only the support element 17, to which a table top can be attached, is visible. The force-fitting connection between the first connecting element 1 and the second connecting element 10 is established by the screw 8 as described above. In the same way, the base element 21 can be attached to the support element 20 by means of a connection between a fourth connecting element (not visible here) and a third connecting element 22, which is arranged at the lower end of the support element 20, wherein the force-fitting connection is established by means of a further screw 23, which serves as a second locking means.

[0025] Fig. 5 shows a further exemplary embodiment of a first connecting element 25, which can, for example, be part of a support element of a table according to the invention. The first connecting element 25 comprises an indentation 26 having a circular cross-section and a groove-shaped recess 27, which is provided at its lower end with a pin- or bolt-shaped element 28 serving as a locking means. The bottom 29 of the indentation 26 is pierced by a through-bore 30. The indentation 26 further has a bore 31 through which a locking means (not shown here), for example a screw, can be introduced into the interior of the indentation 26 for the reversible, force-fitting fixation of a table top and / or a support element.

[0026] Fig. 6 shows a further exemplary embodiment of a second connecting element 35, which can be integrated, for example, into the first connecting element 25 according to Fig. 5 can be inserted or inserted in a form-fitting manner. For this purpose, the second connecting element 35 comprises a bulge 36 which has a circular cross-section and a groove-shaped recess 37 which has a depression 39 at its end facing a support element 38. The bulge 36 is cylindrical and comprises two sections 40, 41 with different outer diameters. The section 41 arranged at the free end of the bulge 36 has a smaller outer diameter than the section 40. The section 40 of the bulge 36 is firmly connected to the rectangular support element 38, to which a table top can be attached. In the exemplary embodiment shown here, the support element 38 is a flat plate.In order to produce a stable connection between the two connecting elements 25, 35, the bulge 36 of the connecting element 35 can fit positively into the indentation 26 of the connecting element 25 according to . Fig. 5 are introduced or inserted. The section 40 of the bulge 36 fits into the indentation 26 and the section 41 of the bulge 36 fits into the bore 30 in a form-fitting manner. In this way, a very stable connection is created between the two connecting elements 25 and 35. Due to the circular cross-sections of the bulge 36 and the indentation 26, these can initially be easily plugged together in any orientation. By turning one of the two connecting elements 25, 35 or one of the parts connected to it (e.g. table top or support element), the two recesses 27 and 37 can then be brought into line so that the pin or bolt-shaped element 28 can snap into the recess 39. The pin or bolt-shaped element 28 therefore actsThe bolt-shaped element 28 acts as a latching means in unit with the recess 39, practically as a locking means that blocks any rotational movement of the second connecting element 35 and thus of a table top attached thereto. By introducing a first locking means, e.g. a screw, into the interior of the indentation 26 until it stops against the section 40 of the bulge 36, a non-positive connection can advantageously be additionally established between the two connecting elements 25, 35. The locking means serves for the reversible, non-positive fixation of the second connecting element 35 and thus of a table top attached thereto. The support element 38 comprises fastening means, in this exemplary embodiment four openings 42 arranged in the four corners of the support element 38, through which the support element 38 and thus the connecting element 35 can be screwed to the table top, for example.

[0027] Fig. Figure 7 shows an exemplary embodiment of a third connecting element 45, which may, for example, be part of a support element of a table according to the invention. For example, the third connecting element 22 according to Fig. 3 and Fig.4 can be designed like the third connecting element 45 shown and described here. The third connecting element 45 comprises an indentation 46 having a circular cross-section and a groove-shaped recess 47, which is part of a second locking means which can, for example, block a rotational movement of a foot element. The bottom 48 of the indentation 46 is pierced by a through-bore 49. The indentation 46 further has a bore 50 through which a locking means (not shown here), for example a screw, can be introduced into the interior of the indentation 46 for the reversible, force-fitting fixation of a foot element and / or a support element. For example, a fourth connecting element, which is connected to a foot element, can be positively inserted or inserted into the third connecting element 45. QUOTES CONTAINED IN THE DESCRIPTION
