Abstract

A worktable with a working surface which can be adjusted in height and/or inclination, which is connected with a table mount by means of an adjustment mechanism. A worktable which can be constructed of individual parts and which can be expanded in width and joined to modular systems is provided by the table mount being a base frame with two supporting columns arranged in the interval of table width and two preferably U-shaped leg members having a central joining portion, a base leg and supporting leg whereby the supporting columns are firmly connected with each other by at least one transverse connecting member and said central joining portion of said leg members adapted to be connected to said supporting columns of said base frame and that said adjustment mechanisms are mounted on the underside of said work surface between said support legs of said leg members and adapted to be connected to said supporting legs.

Claims

1. A worktable with a work surface adjustable in inclination, which is connected to a table mount by means of an adjustment mechanism, characterized by the fact that said table mount comprises a unitary base frame (15) having two supporting columns (16, 17) spaced at a distance from each other corresponding to the width of said worktable, said supporting columns (16, 17) firmly connected to each other by means of at least one transverse connecting member (18) and two unitary leg members (10) each comprising a central joining portion (13), with a base leg (11) and a supporting leg (14) extending from said central joining portion, said central joining portions (13) of said unitary leg members (10) detachably fastened to said supporting columns (16, 17) of said unitary base frame (15) and said adjustment mechanisms (24) mounted on the underside of said work surface (22) adjacent said supporting legs (14) of said leg members (10) and connected to said supporting legs (14) of said leg members (10).

2. A work table having a height adjustable work surface, said worktable comprising:

a unitary base frame (15) having two supporting columns (16,

     17) spaced at a distance corresponding to the width of said worktable, said supporting columns (16,

     17) firmly connected to each other by at least one transverse connecting member (18);

two one-piece leg members (10), each said leg member (10) being -shaped having a vertical joining portion (13) detachably fastened at its rear side to one of said supporting columns (16,

     17) and having a base leg (11) extending from the lower end of its front side a distance about the depth of a worktable surface (22) and a support leg (14) extending from the upper end of its front side a distance less than said depth of said worktable surface;

two adjustment mechanism means (24), mounted on the underside of said worktable surface (22) and connectible to the top of each said support legs (14) whereby said worktable surface (22) is height adjustable.

3. A worktable according to claim 2, wherein the vertical dimension of said base legs (11) and of said supporting legs (14) increases continuously from the free ends to said central joining portion (13).

4. A worktable according to claim 2, wherein said one-piece leg members (10) are hollow in shape and are provided with fastening flanges (38) at the open upper side of said support legs (14).

5. A worktable according to claim 2, wherein said supporting columns (16, 17) are U-shaped in profile, opening to the outer side, and are provided with fastening holes (26) in both U-shaped portions of said supporting columns, and said supporting columns are covered by at least one cover plate (20).

6. A worktable according to claim 2, wherein said transverse connecting member (18) has a U-shaped profile open toward the top and covered by at least one cover plate (21, 28).

7. A worktable according to claim 6, wherein said cover plates (28) have receptacles (29) sized for receiving mating portions (37) of auxiliary devices.

8. A worktable according to claim 6, wherein said cover plates (21) on said transverse connecting member (18) are arranged at normal working height and said support legs (14) of said one-piece leg members (10) terminate at a given interval below said cover plates (21), said interval determined by the lowest adjustment height of said working surface (22) and the height of said adjustment mechanisms (24) at their lowest adjustment.

9. A worktable according to claim 2, wherein said adjustment mechanisms (24) are fully covered by a bellows, and the operating elements of said adjustment mechanisms are arranged on the underside of said work surface (22) between said adjustment mechanisms.

10. A worktable according to claim 2, characterized by said base frame comprising a closed base unit (40, 50) which is provided with hanger moldings (41, 42, 51, 52) on the vertical edges on at least the front side.

11. A worktable according to claim 10, characterized by said closed base unit (40) extending higher than said working surface (22) adjusted to its highest position and bearing a shelf (44) directed toward said working surface (22) at its upper edge.

12. A worktable according to claim 10, characterized by said closed base unit (50) having a height at least double the worktable height and being provided on one side with a removable, horizontally directed cover plate (55) at working level which covers said transverse connecting member (18) which is U-shaped and open toward said cover plate.

13. A worktable according to claim 10, characterized by the vertical narrow sides of said closed base unit (40, 50), being provided with cover plates (20) at least up to working level, which cover U-shaped members forming said support columns (16, 17) open toward said cover plates.

14. A worktable according to claim 10, characterized by at least one shelf (45, 53) having hangers connectible with said hanger moldings (42, 42, 51, 52).

15. A worktable according to claim 10, characterized by said leg members (10) having hangers connectible with said hanger moldings (41, 42, 51, 52).

16. A worktable according to claim 2, wherein said unitary base frame (15) and work surfaces (22) have different widths which are matched to each other.

17. A worktable according to claim 2 additionally adjustable in inclination.
