Abstract

Height-adjustable work table, preferably kitchen table comprising at least one cabinet on top of which a table top is located. The cabinet(s) is located on a number of electrically driven height-adjustable platforms. In that the platforms are mutually retained by at least one connection rail these appear as stable both during the assembly of the work table and of the assembled table. Between a surface, typically a floor on which the platform is located, and an underside of the cabinet a toe kick is placed. This toe kick is telescopic in height such that the toe kick regardless of the adjusted height of the kitchen table shuts off access under the cabinet. The connection rail may constitute an element of the telescopic toe kick.

First claim

1 . Height-adjustable platform for work table, the platform comprising:
a housing; a spindle unit at each end of the housing; the spindle units comprising a tube section with a spindle nut at the top and a foot at the bottom of the tube section; a tubular, spindle with external thread which cooperates with spindle nut in the tube section; a gear wheel at the top of the tubular spindle; a spindle nut arranged a the top of the tubular spindle; a solid spindle with external thread which cooperates with the spindle nut in the tubular spindle; an electric motor with a worm gear; and a gear train driven by the electric motor through the worm gear and the gear train in mesh with the gear wheels of the respective spindle units or expelling and retracting these and thereby raising and lowering the plate element.

2 . Height-adjustable platform according to claim 1 wherein a plate element is fixed to the upper end of the solid spindle.

3 . Height-adjustable platform according to claim 1 , wherein the platform is equipped with an adjusting screw in each corner for compensating for unevenness and slanting of the floor so that the platforms may be leveled.

4 . Height-adjustable platform according to claim 1 , wherein the spindle unit with a lower end is mounted on a plate.

5 . Height-adjustable platform according to claim 1 , wherein the connection rail is arranged at the front of the platforms.

6 . Height-adjustable platform according to claim 1 , wherein a connection rail is arranged at a rear end of the platforms for interconnecting the platforms.

7 . Height-adjustable platform according to claim 1 , wherein the front side of the housing has a longitudinal groove and the connection rail has at least one flap which can be pressed into the groove in the platforms.

8 . Height-adjustable platform according to claim 1 , wherein the connection rail has a U-shaped cross section where the flaps are equipped with snap-locking means such that they may be snapped fixedly around a protruding portion of the platform housing.

9 . Height-adjustable platform according to claim 1 , wherein a toe kick, which is telescopic in height is attached to an end of the housing.

10 . Height-adjustable platform according to claim 9 , wherein the toe kick comprises three mutually telescopic elements.

11 . Height-adjustable platform according to claim 10 , wherein one element of the toe kick is secured to the platform.

12 . Height-adjustable platform according to claim 10 , wherein an intermediate telescopic element of the toe kick is secured to the platform.

13 . Height-adjustable platform according to claim 10 , wherein the connection rail has a groove and that the intermediate element of the toe kick for securing to the connection rail is equipped with a folded flap, which can be pressed into the groove in the connection rail.

14 . Height-adjustable platform according to claim 10 , wherein the connection rail further constitutes an intermediate element of the toe kick.

15 . Height-adjustable platform according to claim 9 , wherein a lowermost telescopic element of the telescopic toe kick likewise is secured to the platform.

16 . Height-adjustable platform according to claim 9 , wherein a topmost telescopic element of the telescopic toe kick likewise is secured to the platforms.

17 . Height-adjustable platform according to claim 1 , wherein the motor is located in a horizontal position in the housing between the two spindle units.

18 . Height-adjustable platform according to claim 1 , wherein there is a gear wheel in connection with the worm wheel and two gear wheels between this gear wheel and the gear wheel at the top of one of the tubular spindle and three gear wheels to the gear wheel at the top of the other tubular spindle.
