Abstract

This work station is comprised of support legs (P) with a stable support base (1a) and uprights (1b) on which pivoting elbows are adapted to form adjacent arms (2a-2b) which are positioned and locked in place in an adjustable angular manner at one end of these arms, the other end bearing supports or work tops (3 and 4) positioned and locked in place in a manner which can be angularly adjusted at will, so that these supports or work tops (3-4) allow effects and uses which are multiple and can be combined together.

Claims

1. A transformable universal work station comprising:

support legs with support base and uprights;

four independent pivoting arms forming two pairs of pivoting elbows;

means for locking each said pair of arms to each other at a fixed angle at one end of each said arm;

means for mounting said elbows on said support legs;

two work tops; and

means for mounting said work tops at the second ends of said arms, including means for independently setting and locking the angles of said work tops to said arms.

2. A work station according to claim 1 in which said uprights of said support legs are hollow in order to allow a sliding mounting of adjustable supports which can be adjusted in height and whose upper ends are formed so as to allow an adjustable angular positioning of said elbows whereby said upper ends of said adjustable supports form yokes in which said elbows are mounted.

3. A work station according to claim 2 in which said adjustable supports have a series of round openings which are used in cooperation with round openings in said uprights and a locking means through said openings in order to set the height of said adjustable supports.

4. A work station according to claim 2 in which said supports are provided with a rack which engages pinions mounted on a shaft whose ends are mounted in said uprights whereby the height of said supports can be adjusted.

5. A work station according to claim 1 where the peak of the angle formed by said first ends of said arms is pierced transversally so that said elbow can be pivoted in said yoke about an axle and where concentrically pierced positioning holes in said elbows and said yoke permit an engagement of a pegging means.

6. A work station according to claim 1 where said second ends of said arms are pierced through in order to permit the insertion of axles each of which engages an appropriate part of said work tops so that said work tops can be pivoted and locked in any desired angular position.

7. A work station according to claim 1 in which the upper parts of said uprights are connected by a service duct which functions as a cross-brace.

8. A work station according to claim 1 in which said work tops have triangular supports attached to said second ends of said arms with axles through concentric holes.

9. A work station according to claim 8 in which locking heads are connected together in pairs to unlock the corresponding work top and in which said locking heads automatically return to the locking position.

10. A work station according to claim 9 in which each said locking head has projecting pins engaging concentric holes in said arms and in said triangular supports.

11. A work station according to claim 10 in which each said locking head slides on the smooth bearing surface of the pivoting axle and in which a spring sliding on said smooth bearing surface presses said locking head away from a ring.

12. A work station according to claim 11 in which each said locking head is integral with a brace which is connected by a turning bushing to a rod whose free end is connected to a control lever which is operated by hand.

13. A work station according to claim 12 in which a pivot axle is fixed under said work top such that by pressing said control lever each said rod axially pulls said heads in opposite directions by means of said braces and in combination with a partial rotation of said turning bushings produces the release of said projecting pins for the angular adjusting of said work tops.
