Definitions

  • the present invention relates to a telescopable column, in particular for items of furniture, such as desks, and to a desk having a telescopable column.
  • New offices are often equipped with height-adjustable desks for improving the ergonomic position of the user and offer the possibility of working while standing or sitting.
  • the high demand for, for example, desks having lifting columns or telescopable desk legs makes an affordable standard system appealing.
  • Lifting columns are conventionally made up of extruded metal tubes with specific lengths.
  • thin composite bodies comprising a support body, are used between the tubes or profiles. Thin elements of this kind are disclosed, for example, in US 2005/0002591 A1. Owing to the intended sliding displacement, the composite bodies are alternately held on an inner tube and on an outer tube in a positionally fixed manner, such that a mutual supporting action is achieved.
  • U.S. Pat. No. 7,908,981 B2 discloses a combination of two different types of sliding elements made of plastic. As a result of the use of grooves which are located along the tubes, linear sliding is made possible.
  • An additional role of the sliding elements consists in compensating for cross-sectional tolerances of the tube profile and for small variations in the dimensions along the tube axis.
  • said role is accomplished by a hardening elastic component (compensation layer) in combination with the composite bodies.
  • it is achieved by using the elasticity of a specially configured region under the sliding element.
  • DE 10020866 A1 it is achieved by feeding the sliding material directly into the space between the tubes.
  • the present invention is therefore based on the object of providing a sliding support which can be produced and assembled in a more cost-effective manner.
  • a telescopable column in particular for items of furniture, such as desks, comprising:
  • At least two telescopic elements which can be displaced axially in one another in a telescope-like manner
  • the sliding support comprises support bodies only in the region of a longitudinal end of an inner one of the two telescopic elements, the support bodies in each case having an abutment zone which forms a sliding surface and having an opposite abutment zone for fastening to the telescopic element, and being fastened to the outer side of the inner telescopic element without tools.
  • said object is achieved by a desk having at least one column according to one of Claims 1 to 10 .
  • the outer telescopic element on the inner side thereof, to have at least one guide groove which extends in the longitudinal direction of said element, and for the sliding surface of the support bodies to have a corresponding lug or guide rib which is designed to slide in the guide groove.
  • the main extent of the sliding surface runs in the longitudinal direction of the inner telescopic element.
  • the main extent of the sliding surface can run transversely with respect to the longitudinal direction of the inner telescopic element.
  • the inner telescopic element has at least one latching opening
  • the support bodies have at least one corresponding latching element on the abutment zone for fastening to the telescopic element.
  • the sliding surface has at least one sliding rib parallel to the guide rib, and the sliding rib has a lower height than the guide rib.
  • At least three, preferably precisely three, of the support bodies are, preferably equidistantly, arranged in one plane in a circumferential manner on the outer side of the inner telescopic element.
  • the support bodies can be arranged in at least two axially offset planes on the outer side of the inner telescopic element.
  • the support bodies can be composed of plastic or to contain plastic.
  • the present invention is based on the surprising realization that, by using a “standard sliding element” with simplified geometry, said element being able to be fastened to the profile in a toolless manner, it is possible to limit, or reduce, the assembly operation to one region of the profile, as a result of which assembly costs can be saved.
  • the “standard sliding element” can be utilized with a large variety of profile diameters, since it covers the profile surface only partially, in particular in a “punctiform” manner.
  • the “standard sliding element” can also be produced and provided in various thicknesses in order to improve the stability of the linear movement and to avoid an excessively large angular deviation of the profiles with respect to one another.
  • the present invention can also be employed in the case of lifting columns which are composed of two or more overlappingly arranged profiles, it being possible for the diameter of the profiles to increase from top to bottom, or alternatively from bottom to top. It is also possible for the tubes or profiles to not have only square, rectangular or circular cross-sectional profiles.
  • FIG. 1 shows a perspective view of a height-adjustable desk having two telescopable columns (lifting columns) according to a particular embodiment of the invention
  • FIG. 2 shows three round tubes, which form a telescopable column, fully extended in a perspective view (on the left), and in a partially transparent side view (on the right);
  • FIG. 3 shows an exploded illustration of a detail view of a sliding support between two telescopic elements (tubes) which can be displaced axially in one another in a telescope-like manner, in a perspective view (on the left) and in a side view (on the right);
  • FIG. 4 shows details of a support body of the sliding support of FIG. 3 in various views
  • FIG. 5 shows an exploded illustration of a detail view of a sliding support between two telescopic elements (tubes) which can be displaced axially in one another in a telescope-like manner, in a perspective view (on the left) and in a side view (on the right), according to a further particular embodiment of the present invention
  • FIG. 6 shows details of a support body of the sliding support of FIG. 5 in various views
  • FIG. 7 shows an exploded illustration of a detail view of a sliding support between two telescopic elements (tubes) which can be displaced axially in one another in a telescope-like manner, in a perspective view (on the left) and in a side view (on the right), according to a further particular embodiment of the invention;
  • FIG. 8 shows details of a support body of the sliding support of FIG. 7 in various views.
  • FIG. 9 shows an exploded illustration of a detail view of a sliding support between two telescopic elements (tubes) which can be displaced axially in one another in a telescope-like manner, in a perspective view (on the left) and in a side view (on the right), according to a further particular embodiment of the invention.
  • the height-adjustable desk 10 shown in FIG. 1 has, inter alia, a desk top 12 on a desk frame 14 which has, inter alia, a telescopable column 16 on each side and a respective desk foot 18 .
  • the columns 16 have a square or rectangular cross section. It goes without saying that the cross section can for example also be round or oval.
  • the telescopable column 16 shown by way of example in FIG. 2 for example for a desk, comprises three telescopic elements 20 , 22 and 24 which can be displaced axially in one another in a telescope-like manner, wherein, in this example, the uppermost telescopic element 24 can be displaced in the interior of the middle telescopic element 22 , and the middle telescopic element 22 can be displaced in the interior of the lower telescopic element 20 .
  • This is made possible by a respective sliding support 26 or 28 which, in this example, is arranged in the region of the lower longitudinal end 30 of the middle telescopic element 22 and in the region of the lower longitudinal end 32 of the upper telescopic element 24 , respectively.
  • Each of the two sliding supports 26 and 28 has support bodies 34 having an outer sliding surface, which support bodies, in this example, are of identical design and are in each case equidistantly arranged in a circumferential manner in two planes 36 and 38 which are offset axially from one another.
  • support bodies 34 are arranged, at a spacing of 90° with respect to one another, in a circumferential manner in each plane.
  • FIG. 3 shows a further sliding support 40 .
  • Said sliding support is arranged in the region of the lower longitudinal end of the upper telescopic element 44 , which slides in the lower telescopic element 46 .
  • the sliding support 40 comprises support bodies 48 .
  • the support bodies 48 are identical, and have an abutment zone 50 which forms a sliding surface and have an opposite abutment zone 52 for fastening to the upper telescopic element 44 (see FIG. 4 ).
  • the fastening to the upper telescopic element 44 takes place by way of, in each case, two latching openings 54 which are spaced apart above one another in the axial direction and corresponding latching elements 56 on the abutment zone 52 (see also FIG. 4 ).
  • each support body 48 has a guide rib 58 which extends in the axial direction of the upper telescopic element 44 and which slides in a guide groove 60 which extends in the longitudinal direction of the lower telescopic element 46 on the inner side 62 of the lower telescopic element 46 .
  • the support bodies 48 are arranged on the outer side 64 of the upper telescopic element 44 , and specifically, in this example, in two planes 66 and 68 which are offset above one another in the axial direction, with four support bodies 48 being equidistantly arranged over the circumference in each plane.
  • the support bodies 48 in one plane lie, with respect to corresponding support bodies 48 in the other plane, in the axial direction, on a line L.
  • support bodies 70 which is shown in FIG. 5 and 6 differs from the support bodies shown in FIG. 3 and 4 substantially in that the main extent H (see FIG. 6 ) runs not in the longitudinal direction of the upper telescopic element 44 but rather transversely thereto.
  • the support bodies 70 on the abutment zone 52 also have only one, in this example central, latching element 56 . Accordingly, in the lower longitudinal end 42 of the upper telescopic element 44 , only one respective latching opening 54 is required in order to fasten the support body 70 to the upper telescopic element 44 .
  • the support bodies 70 shown in FIGS. 5 and 6 in each case have two parallel sliding ribs 72 on both sides of the guide rib 58 .
  • support bodies 74 which is shown in FIG. 7 and 8 differs from the support bodies shown in FIG. 5 and 6 substantially in that, instead of a central latching element 56 , a respective latching lug 76 (see in particular FIG. 8 ) as latching element is provided on each short side of the abutment zone 52 . Accordingly, the upper telescopic element 44 has corresponding latching openings 54 in the region of the lower longitudinal end 42 .
  • the sliding support shown in FIG. 9 differs from the sliding support shown in FIG. 3 substantially in that the support bodies 80 in one plane 82 are offset by 45° with respect to the support bodies 80 in a plane 84 which is offset axially thereto.
  • the lower telescopic element 46 on the inner side 62 thereof, has corresponding guide grooves 60 which are arranged at an angle of 45° in a circumferential manner.
