Abstract

A modular laboratory furniture system includes freestanding tubular frame modules (22) and freestanding table (36) arranged about a room in a preplanned configuration. The system further includes mobile carts (40) movable about the room. The frame modules (22) and tables (36) each mount a horizontal work surface (50). Pairs of spaced-apart common support means (38) mount the work surfaces (50) and also are used to construct the carts (40). The common support means (38) includes a hollow vertical leg (56, 58), a bracket member (52, 54) and means for securing one portion of the leg (56, 58) to the bracket member (52, 54). The base portion (92) of the bracket member (52, 54) has a perimeter which mates with that of the leg (56, 58). Detachably secured to the legs (56, 58) of the spaced-apart support means (38) are rails (60, 61). The rails (60, 61) support at least one storage component on the frame module ( 22), table (36) and carts (40). The common support means (38) allow for mounting of work surfaces (50) to the frame modules (22) and tables (36) and the construction of carts (40) using a minimum of parts and provide for versatility in making changes in the sytem.

Claims

1. A modular laboratory furniture system for arrangement in a room comprising:

freestanding tubular frame modules and freestanding tables, all of which are selectively arranged about said room in a preplanned configuration;

mobile carts movable about said room between said frame modules and freestanding tables;

each of said frame modules and tables mounting a horizontal work surface;

pairs of spaced-apart common support means for mounting said work surfaces to said frame modules and tables and forming side of said mobile carts;

each of said common support means including

a hollow vertical leg of rectangular cross-section;

a bracket member having an extension arm for mounting to an underside of said work surface or for providing a bottom support and a base portion for mounting to said vertical leg;

means mounting one portion of said leg to said base portion of the bracket member;

said base portion mating with said cross-sectional configuration of said vertical leg;

rails each of which is detachably secured to a pair of the hollow vertical legs of a pair of spaced-apart support means;

means mounting said work surface to said extension arms of certain of said bracket members;

storage components releasably supported on said frame modules, tables and carts;

at least one of said storage components secured to at least one said rail;

wherein said common support means for mounting said work surfaces to said frame modules and tables provides for construction of said system using a minimum of parts and provides for versatility in making changes to said system.

2. The system of claim 1 wherein said bracket member is a unitary member having two parallel side walls joined by perpendicular webs integrally formed with said side walls.

3. The system of claim 1 wherein said means mounting said leg to said bracket member includes rods fastened between said bracket member and a lower portion of said vertical leg.

4. The system of claim 3 wherein said lower portion of said leg is a separate cap member.

5. The system of claim 1 wherein said rail is a hollow extruded member having a generally rectangular cross-section.

6. The system of claim 5 wherein said rail includes a lip for mating with an attachment member on said storage components.

7. The system of claim 1 further including hanger means on said frame modules for releasably supporting said support means.

8. The system of claim 7 further including hanger clips fastened to said bracket members and releasably received on said hanger means.

9. The system of claim 1 including levelling means for adjusting the horizontal orientation of the work surfaces.

10. The system of claim 9 wherein said levelling means includes means mounting an upper portion of said support means to a vertical support for pivoting movement about a horizontal axis and means for pivoting said support means about said horizontal axis.

11. The system of claim 10 wherein said means for pivoting includes a block member secured stationary relative to said support means and a rod threadedly received in said support member having an end portion bearing against said block member wherein rotation of said rod causes said support means to angularly displace relative to said block member and pivot about said horizontal axis.

12. The system of claim 1 wherein the freestanding tables include base means for supporting said table on the floor of the room.

13. The system of claim 12 wherein said base means comprises another of said bracket member having said extension arm thereof positioned adjacent the floor of the room.

14. The system of claim 1 wherein the bracket members of each of said mobile carts are mounted to the bottom portions of said vertical legs so as to provide a bottom support, cap members are mounted to the top portions of each of said vertical legs, and said means mounting said leg to said bracket member also mounts said cap members to said legs.

15. The system of claim 14 wherein said mobile carts include wheel means mounted to bracket member for rolling said carts about said room.

16. An assembly for supporting a work surface comprising:

a hollow vertical leg having an elongated rectangular horizontal cross-section which is uniform in dimensions throughout the length thereof;

a first hollow bracket member including an extension arm disposed generally perpendicular to the longitudinal axis of said leg for mounting to an underside of a work surface and a base portion collinearly arranged with said leg for mounting to said vertical leg, a bottom surface of said base being congruent with an upper edge of said hollow vertical leg;

a second hollow bracket having an upper surface portion of a shape congruent with said rectangular cross-section of said hollow vertical leg, said upper surface portion being in contact with a lower edge of said hollow leg; and

means extending from said first bracket to said second bracket through said hollow leg for securing said vertical leg to said first and second bracket members.

17. The bracket assembly of claim 16 wherein said extension arm is a unitary member including spaced-apart parallel side walls joined by webs integrally formed with said side walls.

18. The bracket assembly of claim 16 wherein said means securing said leg to said bracket members includes rods fastened to said first and second brackets.
