Abstract

Slider element for lifting columns, preferably for height-adjustable tables, said lifting columns comprise at least two profiles 10,11 arranged telescopically relative to each other, where the slider element 1 has a first slider 2 and a second slider 3 between which there is a designated breaking line 4. The slider element is mounted with the second slider 3 on the outer side of the inner profile 10, and is subsequently guided into the hollow of the outer profile 11, by which the first slider 2 affixes itself to the inner side of the outer profile and when the two profiles are retracted further, the designated breaking line 4 between the first and the second slider 2,3 will break, by which they appear as two separate sliders mounted on a profile each. Thus, a simplified mounting of the sliders is achieved. In addition, it can be constructed such that the sliders are completely concealed within the lifting column.

First claim

The invention claimed is:

1. A slider element for lifting columns which lifting column comprises a first profile ( 10 ) and a second profile ( 11 ) arranged telescopically relative to each other, and where the slider element is configured to be arranged between the profiles, wherein the slider element ( 1 ) has a first slider ( 2 ) connected to a second slider ( 3 ) with a designated breaking line ( 4 ) located between the first slider ( 2 ) and the second slider ( 3 ), wherein the slider element ( 1 ) is configured to break at the designated breaking line ( 4 ) when the first slider ( 2 ) is pulled away from the second slider ( 3 ).

2. The slider element according to claim 1 , wherein the first and second slider ( 2 , 3 ) are located in continuation of each other, and wherein the designated breaking line ( 4 ) is located between the adjacent ends of these.

3. The slider element according to claim 2 , wherein the designated breaking line ( 4 ) is constituted by a pin on the end of one of the sliders ( 2 ) which is positioned between two pins on the end of the other slider ( 3 ), and wherein the pins are connected by a string.

4. The slider element according to claim 1 , wherein each slider ( 2 , 3 ) comprises a base element ( 5 ), on which there is a rise ( 6 ) with a sliding surface ( 7 ).

5. The slider element according to claim 4 , wherein the first slider ( 2 ) at each side comprises at least one resilient element ( 8 ), a tongue, which at an angle protrudes over the outer side of the base element ( 5 ).

6. The slider element according to claim 1 , wherein the second slider ( 3 ) comprises a base element ( 5 ) with at least one stud ( 9 ) located on the inner side of the base element ( 5 ), the at least one stud ( 9 ) being configured for insertion into a recess ( 12 ) in the first profile ( 10 ).

7. The slider element according to claim 6 , wherein the at least one stud ( 9 ) has a tongue ( 9 b ) constructed to grip behind the inner side of the first profile when the stud is inserted into the recess in the first profile.

8. The slider element according to claim 6 , wherein the inner side of the base element includes a plurality of studs, and at least one stud ( 9 a ) has an extended length configured to protrude into a hollow ( 30 a , 33 a ) on the first profile the extended length stud further being configured to grip into a recess in an end piece ( 30 , 33 ) of the first profile.

9. The slider element according to claim 1 , wherein the outer side of the slider element is equipped with a longitudinal rib ( 25 ) for cooperating with an axially running groove ( 26 ) in the second outer profile.

10. The slider element according to claim 9 , wherein the second slider ( 3 ) comprises a base element ( 5 ) with at least one stud ( 9 ) located on the inner side of the base element, the at least one stud ( 9 a ) being located below the rib ( 25 ).

11. The slider element according to claim 1 wherein the slider element is cylindrical and configured for insertion over a profile and wherein the slider element comprises multiple sets of first and second sliders ( 2 , 3 ).

12. A lifting column comprising:
at least two profiles ( 10 , 11 ), a first profile ( 10 ) and a second profile ( 11 ), arranged telescopically relative to each other as the first profile ( 10 ) is intended for insertion into the second profile ( 11 ), and
at least one slider element ( 1 ) according to claim 1 .

13. The lifting column according to claim 12 , wherein recesses ( 12 ) for receiving studs ( 9 ) on the second slider ( 3 ) of the slider element are provided in the sides of the first profile ( 10 ), and on the inner side of the second profile there are indentations ( 13 ) for receiving a protruding resilient element ( 8 ) located on the first slider ( 2 ).

14. A method for mounting a slider element on a lifting column, the slider element comprising a first slider and a second slider between which there is a designated breaking line, wherein the lifting column comprises a first, inner profile ( 10 ) and a second, outer profile ( 11 ) arranged telescopically relative to each other, the method comprising the steps of:
mounting the slider element ( 1 ) on the outer side of the inner profile ( 10 ) by pressing one or more studs ( 9 ) located on the second slider ( 3 ) into one or more through-going holes ( 12 ) located on the inner profile;
inserting the inner profile ( 10 ) with the mounted slider element ( 1 ) into the hollow of the outer profile ( 11 ), until one or more resilient elements ( 8 ) located in the side of the first slider ( 2 ) snap into one or more indentations ( 13 ) located on the inner side of the outer profile ( 11 ); and
sliding the inner profile ( 10 ) further into the outer profile ( 11 ) until the slider element ( 1 ) breaks along the designated breaking line ( 4 ) between the first and the second slider ( 2 , 3 ), resulting in two separate sliders each mounted on one of the profiles ( 10 , 11 ).

15. A table equipped with one or more lifting columns according to claim 12 .
