First Claim
Patent Images
1. A collapsible table, comprising:
- a framework including a plurality of support members, said support members being joined together by connectors, said connectors including upper and lower connectors to which said support members are pivotally attached, which allow movement such that said framework is moveable from a collapsed configuration to an extended configuration;
said lower connectors act as support feet, said support feet moving generally towards a central area as said framework moves from said extended configuration towards said collapsed configuration;
a table surface attached to said framework; and
at least one elastic retaining element which serves to maintain tension in said table surface so that said table surface is urged to resist sagging when said framework is in said extended configuration, said upper and lower connectors including attachments sites for attaching said at least one said elastic retaining element.

Abstract
A collapsible table (10), having a framework (12) including a number of support members (14) which are joined together by connectors (21, 26) which allow movement such that the framework (12) is moveable from a collapsed configuration (70) to an extended configuration (36). A table surface (16) is attached to the framework (12). There is also at least one elastic element (31) which serves to maintain tension in the table surface (16) so that the table surface (16) is urged to resist sagging when the framework (12) is in the extended configuration (36).

1. A collapsible table, comprising:
-
a framework including a plurality of support members, said support members being joined together by connectors, said connectors including upper and lower connectors to which said support members are pivotally attached, which allow movement such that said framework is moveable from a collapsed configuration to an extended configuration;
said lower connectors act as support feet, said support feet moving generally towards a central area as said framework moves from said extended configuration towards said collapsed configuration;
a table surface attached to said framework; and
at least one elastic retaining element which serves to maintain tension in said table surface so that said table surface is urged to resist sagging when said framework is in said extended configuration, said upper and lower connectors including attachments sites for attaching said at least one said elastic retaining element. - View Dependent Claims (2, 3, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 17, 18, 19, 20, 21, 22)
said at least one elastic retaining element attaches to said framework to maintain it in said extended configuration, and thereby maintains tension in said table surface.
-
-
3. A collapsible table as in claim 1, wherein:
said at least one elastic retaining element attaches to said table surface to maintain tension in said table surface, and thereby urges said framework to remain in said extended configuration.
-
5. A collapsible table as in claim 1, wherein:
said at least one elastic retaining element attaches between one of said upper connectors and one of said lower connectors.
-
6. A collapsible table as in claim 5, wherein:
said at least one elastic retaining element includes at least one hook by which said elastic retaining element attaches to an attachment site of one of said upper connectors.
-
7. A collapsible table as in claim 5, wherein:
said at least one elastic retaining element includes at least one hook by which said elastic retaining element attaches to an attachment site of one of said lower connectors.
-
8. A collapsible table as in claim 5, wherein:
said at least one elastic retaining element includes two hooks by which said elastic retaining element attaches to an attachment site of one of said upper connectors and an attachment site of one of said lower connectors.
-
9. A collapsible table as in claim 5, wherein:
-
said framework includes four upper corners, each of which includes an upper connector; and
said at least one elastic retaining element includes four elastic retaining elements, one of which is attached to each of said upper connectors.
-
-
10. A collapsible table as in claim 9, wherein:
-
said framework further includes four lower corners, each of which includes a lower connector; and
said four elastic retaining elements, each being attached between one of said upper connectors and one of said lower connectors.
-
-
11. A collapsible table as in claim 1, wherein:
said table surface is configured in a shape chosen from the group consisting of square, rectangular, hexagonal, octagonal, and round.
-
12. A collapsible table as in claim 1, wherein:
said support members are configured to have a cross-sectional shape chosen from the group consisting of square tubular, rectangular tubular, round tubular, square solid, rectangular solid and round solid.
-
13. A collapsible table as in claim 1, wherein:
said table surface is detachable from said framework.
-
14. A collapsible table as in claim 1, wherein:
said table surface is composed of material selected from the group comprising fabric, flexible plastic, chain mesh, woven material, and linked plates.
-
15. A collapsible table as in claim 1, wherein:
said at least one elastic retaining element is part of the table surface.
-
17. A collapsible table as in claim 1, wherein:
said tension in said elastic retaining elements opposes the movement of said support feet toward said central area, thus serving to maintain said table in said extended position, and maintaining tension in said table surface.
-
18. A collapsible table as in claim 1, wherein:
said support feet move in a generally radial direction from said central area, when said framework moves from a collapsed configuration towards an extended configuration.
-
19. A collapsible table as in claim 1, wherein:
-
said support members are pivotally connected by mid-point pivots, as well as being pivotally connected at upper and lower connectors, so that said framework expands or contracts as a whole; and
said at least one elastic retaining element is a single retaining element.
-
-
20. A collapsible table as in claim 1, wherein:
-
said support members are pivotally connected by mid-point pivots, as well as being pivotally connected at upper and lower connectors, so that said framework expands or contracts as a whole; and
said at least one elastic retaining element is a pair of retaining elements.
-
-
21. A collapsible table as in claim 1, wherein:
said upper and lower connectors are interchangeable.
-
22. A collapsible table as in claim 1, wherein:
said at least one elastic retaining element is part of a border strip surrounding a central portion of said table surface.
-
4. A collapsible table, comprising:
-
