Collapsible tables

Claim 2

A collapsible table including a working plate and comprising: a crosspiece for bracing said working plate, said crosspiece including a lengthened portion cooperating with said working plate and two opposite ends; two uprights, each one of said two uprights being rigidly fixed to one corresponding of said two opposite ends and extending by one side transversely to said lengthened portion; two supporting elements for supporting said working plate, each of said supporting elements including a recess to house said crosspiece, a pair of supporting surfaces transversal to said recess for cooperating with said working plate, and a hole for being passed through by one corresponding of said two uprights; and fixing members for removably securing said pair of supporting surfaces and said lengthened portion of said crosspiece to said working plate.

Claim 3

A collapsible table according to claim 1, wherein said working plate has a rectangular form having two edges longer than the adjacent two and comprises a working surface and a bottom surface, a portion of said recess bearing said crosspiece against said bottom surface, parallely to said longest edges.

Claim 4

A collapsible table according to claim 2, wherein said fixing members comprise a plurality of screw members and each of said supporting elements comprises: a panel including two interconnected sheet-metal walls defining an internal space therebetween and provided with bent edges defining said supporting surfaces and having holes for said plurality of screw members, said recess being formed in one of said two interconnected sheet-metal walls; and a transversal element connected to one of said interconnected sheet-metal walls in proximity of said recess, and in which said first mentioned hole is formed, each of said uprights being disposed inside said internal space defined by said two interconnected sheet-metal walls.

Claim 5

A collapsible table according to claim 3, wherein each of said supporting elements further comprises a supporting crosspiece connected to a lowest portion of said panel and provided with a series of feet.

Claim 6

A collapsible table according to claim 3, wherein each of said supporting elements includes a supporting crosspiece connected to a lowest portion of said panel and wherein said supporting crosspiece constitutes a transverse brace for said working plate spanning said two supporting elements, each of said supporting crosspiece comprising a support hole and each of said uprights having one end formed as a pin, said pin being insertable in said support hole of said supporting crosspiece, when said panel is mounted to said working plate.

Claim 7

A collapsible table according to claim 1, wherein said two uprights are substantially perpendicular to said lengthened portion and said crosspiece has a section substantially rectangular, said recess being defined by a U-shaped slot formed in each of said supporting elements.

Claim 8

A collapsible table comprising a working plate including a working surface and a bottom surface opposite to said working surface, two supporting plates each including two supporting surfaces for being connected with said bottom surface of said working plate, fixing means for removably fixing said supporting surfaces to said bottom surface, and a crosspiece member for interconnecting said supporting plates with said bottom surface, said crosspiece including a portion for contacting said bottom surface and two legs substantially perpendicular to said portion, each of said supporting plates further comprising engagement means for removably engaging one of said legs with one corresponding of said supporting plates between said two supporting surfaces and for bearing said portion of said crosspiece against said bottom surface of said working plate when said fixing means fix said supporting surfaces to said bottom surface.

Claim 9

A collapsible table comprising a working plate including a working surface and a bottom surface opposite to said working surface, two supporting plates each including two supporting surfaces for being connected with said bottom surface of said working plate, fixing means for removably fixing said supporting surfaces to said bottom surface, and a crosspiece member for interconnecting said supporting plates with said bottom surface, said crosspiece including a portion for contacting said bottom surface and two legs substantially perpendicular to said portion, each of said supporting plates further comprising engagement means for removably engaging one of said legs with one corresponding of said supporting plates between said two supporting surfaces and for bearing said portion of said crosspiece against said bottom surface of said working plate when said fixing means fix said supporting surfaces to said bottom surface.

Claim 10

A table according to claim 7, wherein said engagement means comprise housing parts of said crosspiece in recesses defined by parts of said supporting plates adapted to cooperate with said crosspiece.

Claim 11

A table according to claim 8, wherein each of said supporting plates comprises two interconnected sheet-metal walls, said recess being formed in one of said walls and wherein at one end of said two sheet-metal walls is fixed a section, located in a zone of the supporting plate distant from said bottom surface, and in which a hole is formed, a free end of each of said legs being arranged to engage said hole when said supporting plate is fixed to said bottom surface of said table.
