Description

[0001] The invention relates to a table frame for a height-adjustable table and a height-adjustable table with such a table frame, in particular a table frame with several table legs.

[0002] Height-adjustable tables use multiple legs to improve stability and increase load-bearing capacity. However, a problem arises: if the legs extend unevenly for height adjustment, the tabletop can become uneven, and the legs can become jammed and jammed.

[0003] Therefore, solutions for synchronizing the movement of multiple table legs are known, in which the movements of the individual table legs are synchronized via a connecting shaft. This connecting shaft is coupled via a chain or toothed belt to the relative movement of the table legs' movable components in order to synchronize this relative movement. In further embodiments, the connecting shaft is linked via a gearbox to adjusting spindles in the individual table legs. However, these solutions involve the use of many complex components.

[0004] Patent EP 1 987 734 B1, filed by the applicant, discloses a table frame in which the table legs are connected to one another by means of at least one band which is deflected such that a relative displacement between an inner column and an outer column of a first table leg results in a synchronous relative displacement between an inner column and an outer column of a second table leg. Although relatively simple components are used, many mechanical components are nevertheless required to achieve stable synchronization.

[0005] Therefore, the invention is based on the objective of providing a table frame for a height-adjustable table that does not have the above disadvantages and that allows it to be built cost-effectively.

[0006] The problem is solved by a table frame according to claim 1 and a height-adjustable table according to claim 15. Advantageous further developments are contained in the dependent claims.

[0007] According to one aspect of the invention, a table frame has at least two telescopic columns, wherein a first telescopic column and a second telescopic column each comprise: an outer column, an inner column arranged axially displaceable to the outer column in a first direction, wherein the telescopic columns are designed such that the inner column can be extended from the outer column in the first direction towards a tabletop of the table, and a drive device which is arranged at least partially inside the inner column, wherein the drive device comprises a first drive component which is stably mounted on the inner column in the first direction relative to the inner column, and a second drive component which is stably mounted on the outer column in the first direction relative to the outer column, and the first drive component and the second drive component are movable relative to each other in the first direction.The table frame further comprises a first band-like synchronization device which is connected in the region of one of its ends to the outer column of the second telescopic column, wherein the table frame is designed such that a relative displacement between the inner column and the outer column of the first telescopic column by means of the first band-like synchronization device results in a synchronous relative displacement between the inner column and the outer column of the second telescopic column, and the first band-like synchronization device is connected in the region of its other end to the second drive component of the drive device of the first telescopic column.

[0008] By connecting the first band-like synchronization device to the second drive component, which is attached to the outer column, it is not necessary to provide further complex retaining elements to connect the other end of the first band-like synchronization device to the outer column of the first telescopic column. This allows the table frame to be assembled cost-effectively with fewer individual parts.

[0009] In In an advantageous further development of the table frame, the first telescopic column has a first deflection pulley and a second deflection pulley, and the second telescopic column has a third deflection pulley, wherein the first and second deflection pulleys are connected to the inner column of the first telescopic column and the third deflection pulley is connected to the inner column of the second telescopic column. The first belt-like synchronizing device is configured to be deflected by the first deflection pulley, in particular by 180° upwards, by the second deflection pulley of the first telescopic column, in particular by 90° towards the first telescopic column, and by the third deflection pulley of the second telescopic column, in particular by 90° downwards.

[0010] By using these deflection pulleys, it is possible to run the first synchronization device inside the table frame, thus enabling safe and visually appealing synchronization.

[0011] According to a further advantageous embodiment of the table frame, the table frame has a second band-like synchronization device which is connected at its first end to the second drive component of the drive unit of the second telescopic column and at its second end to the outer column of the first telescopic column. The table frame is designed such that a relative displacement between the inner column and the outer column of the second telescopic column by means of the second band-like synchronization device results in a synchronous relative displacement between the inner column and the outer column of the first telescopic column.

[0012] By providing this second ribbon-like synchronization device, it is possible for the two telescopic columns to move in perfect synchronicity in both the first direction and a second, opposite direction.

[0013] According to a further advantageous embodiment of the table frame, the second telescopic column has a fourth and a fifth deflection pulley, and the first telescopic column has a sixth deflection pulley. The fourth and fifth deflection pulleys are connected to the inner column of the second telescopic column, the sixth deflection pulley is connected to the inner column of the first telescopic column, and the second belt-like synchronizing device is configured to be deflected by the fourth deflection pulley, in particular by 180° upwards, and by the fifth deflection pulley of the second telescopic column, in particular by 90° towards the first telescopic column, and to be deflected by the sixth deflection pulley of the first telescopic column, in particular by 90° downwards.

[0014] By using these deflection pulleys, it is possible to run the second synchronization device inside the table frame, thus enabling safe and visually appealing synchronization.

[0015] In a further advantageous development of the table frame, at least one of the first and the second telescopic columns each has a separate roller fastening element attached to the inner column in the area of ​​one end of the inner column in the opposite direction to the first direction, which is designed to rotatably attach the first deflection roller or the fourth deflection roller to the inner column.

[0016] The separate roller mounting element makes it possible to connect the first or fourth deflection roller to the inner column without requiring extensive machining of the inner column.

[0017] In a further advantageous development of the table frame, the roller mounting element has laterally projecting projections, the inner column has openings or, from its inner surface, recesses in the area of ​​the end of the inner column opposite the first direction, and the projections of the roller mounting element and the openings or recesses of the inner column are designed so that the projections engage in the openings or recesses and fix the roller mounting element in any direction parallel to the first direction to the inner column.

[0018] By providing the laterally projecting protrusions in conjunction with the recesses or openings, it is possible to easily mount the roller mounting element on the inner column.

[0019] According to an advantageous embodiment of the table frame, the roller mounting element is made of plastic.

[0020] This enables cost-effective production of the roller mounting element, which can be easily and precisely adapted to the inner column.

[0021] In an advantageous further development of the table frame, the first and second telescopic columns each have a drive component fastening element by means of which the first drive component of the drive device can be attached to the inner column, wherein the drive component fastening element has a bearing device which is designed to rotatably mount at least one of the second or sixth deflection rollers or the third or fifth deflection rollers.

[0022] This design of the drive component mounting element makes it possible to attach the first drive component to the inner column and to rotatably mount a corresponding deflection pulley without the need for additional components, thus reducing the number of components and therefore manufacturing costs.

[0023] According to a further advantageous embodiment, the drive component fastening element has laterally projecting projections, the inner column has openings or, from its inner surface, recesses in the area of ​​the end of the inner column in the first direction, and the projections of the drive component fastening element and the openings or recesses of the inner column are designed such that the projections engage in the openings or recesses and fix the drive component fastening element in any direction parallel to the first direction.

[0024] By providing the laterally protruding projections in conjunction with the recesses or openings, it is possible to easily mount the drive component mounting element.

[0025] In an advantageous design of the table frame, the drive device has a gas spring.

[0026] The gas spring has a design that is convenient for placement in a telescopic column, and its extension force can be easily changed if required.

[0027] In an advantageous further development of the table frame, the gas spring has a locking device designed to lock the gas spring in a position within its stroke.

[0028] This allows the tabletop to be easily fixed at a desired height within the lifting range.

[0030] In addition to attaching the first drive component of the drive unit to the inner column or storing deflection rollers, a further function is integrated into the drive component fastening element, so that further additional components can be saved.

[0031] According to an advantageous embodiment, the telescopic column has a first band fastening element designed to connect the first or second band-like synchronization device directly to the second drive component of the respective drive device.

[0032] This makes it possible to easily attach the synchronization devices to the outer column via the second drive component.

[0034] By constructing the synchronization device in two sections and connecting each section with corresponding components of the telescopic columns, it is possible to use telescopic columns of different widths for the table frame, whereby connecting the two sections to the one synchronization device is then easily possible, thus saving costs during assembly.

[0035] According to another aspect of the invention, a height-adjustable table has a previously described table frame with the corresponding advantages.

[0036] The invention is explained below with reference to exemplary embodiments and the accompanying drawings.
