Abstract

A work table is disclosed having three end-to-end abutted sections joined by adjustable longitudinal bars for forming a rigid table from one or more of the respective sections. Four sets of adjustable bars extend longitudinally of the table and fit varying lengths of the table comprising from 1 to 3 sections of the abutted table members. The bars extend in parallel to the longitudinal length of the table, provide rigidity to the respective table sections as well as extend between the respective sections when one or more leaves are joined. Cross X-type legs are provided with a variable pivot. The variable pivots enables the crossover point of the legs to be varied so that the table may be disposed at various heights and inclinations about its longitudinal length. The legs are provided at their upper end with U-sectioned channels having locking wing nuts for keying at selected locations to the longitudinal bars. The legs at their lower end include parallel extending shoe members to impart a longitudinal rigidity as well as a side-by-side rigidity to the supported work surface of the table. The table when disassembled provides for convenient storage and shipment in a small contained package. Provision is made for the mounting of a quilting rack.

Claims

1. An adjustable table comprising in combination;

first and second table leaf members, each said table leaf member including;

a membrane having a flat working surface;

a plurality of transverse and a plurality of longitudinal gussets attached to the back side of said membrane to form reinforcement for said membrane whereby said membrane is stiffened into a table leaf member having an upwardly disposed working surface;

a plurality of pipes for supporting said table leaf members at said gussets and extending between said gussets to join said table leaf members into a unitary upwardly disposed table;

said plurality of transverse gussets defining respective aligned circular holes for snugly receiving and surrounding said pipes between said plurality of transverse gussets with said table leaf members registered one to another whereby said pipes are fastened to said table leaf members and cause said table leaf members to be fastened and registered one to another;

locking means extending between said table leaf members for drawing said table leaf members over said pipes into snug side-by-side engagement at adjacent edges of said leaf members;

two pairs of legs members, each said pair of leg members including;

first and second leg members with each leg member having an elongate longitudinal member having an upper end and a lower end;

a member for fastening each said leg to said pipes including a normal affixed U-sectioned channel member at the upper end of each of said leg member;

a normally affixed shoe member affixed to the lower end of said leg member parallel to said U-sectioned channel member, said shoe member extending beyond said leg to transversely support said leg at least one side thereof;

said U-sectioned channel member dimensioned to received said table leaf member at one of said pipes;

means for clamping said pipes to said U-sectioned channel members and;

means for pivotally mounting said leg pairs together whereby said pairs of leg members pivotally and rigidly support said table in a cross-based disposition.

2. The invention of claim 1 and wherein said clamping means includes a wing nut threaded to said a side of said U-sectioned member wedging said pipe in said U-sectioned members.

3. The invention of claim 1 and wherein said table includes three leaf members.

4. The invention of claim 1 and wherein said legs can be pivotally joined at variant locations thereon.
