Abstract
Abstract A work table for carrying tools thereon (e.g. a power saw) which is rollably transportable between different locations and collapsible in a manner which facilitates loading of the work table onto the the bed of a truck. The legs of the work table are pivotally attached thereto and moveable between an upright position and a collapsed horizontal position generally beneath the horizontal top surface of the work table. A first pair of casters are attached to the front legs of the table and a second pair of casters are attached to a frame extension member which is movable between a coplanar position substantially beneath the top surface and a position extending horizontally outward from an end thereof; the first and second pairs of casters being generally coplanar when the work table is in its collapsed position so as to allow rollable movement of the carrier on the first and second pairs of casters.

Claim 1
Independent Claim
280 words
A portable collapsible work table, comprising: a. a generally rectangular frame having a substantially horizontal top surface carried thereby suitable for securing a tool thereto, said support frame having oppositely disposed first and second sides and first and second ends; b. a first pair of legs pivotally mounted to said support frame adjacent said first end of said support frame; c. a second pair of legs pivotally mounted to said support frame adjacent said second end of said support frame; d. guide means attached to said first and second sides of said support frame; e. frame extension means carried by said guide means and moveable between a first generally horizontal position substantially beneath said horizontal surface and a second position extending horizontally outward from said first end of said support frame; f. a wheel rollably attached to each leg of said first pair of legs; g. wheel means rollably attached to said frame extension means and extending downwardly therefrom to a position generally coplanar with said wheels connected to said first pair of legs when said legs are in said second position; h. a first and second strut member eAch having a first end attached to a different one of said first pair of legs, a second end attached to said support frame, and a pivotable break point between said first and second legs; and i. first and second cable means each having a first end fixed to said support frame adjacent said first end thereof and a second end fixed to a different one of said first and second strut members for moving said struts at said pivotable break point causing said legs to pivot to said second position.
Claim 2
Dependent Claim
280 words
A portable collapsible work table, comprising: a. a generally rectangular frame having a substantially horizontal top surface carried thereby suitable for securing a tool thereto, said support frame having oppositely disposed first and second sides and first and second ends; b. a first pair of legs pivotally mounted to said support frame adjacent said first end of said support frame; c. a second pair of legs pivotally mounted to said support frame adjacent said second end of said support frame; d. guide means attached to said first and second sides of said support frame; e. frame extension means carried by said guide means and moveable between a first generally horizontal position substantially beneath said horizontal surface and a second position extending horizontally outward from said first end of said support frame; f. a wheel rollably attached to each leg of said first pair of legs; g. wheel means rollably attached to said frame extension means and extending downwardly therefrom to a position generally coplanar with said wheels connected to said first pair of legs when said legs are in said second position; h. a first and second strut member eAch having a first end attached to a different one of said first pair of legs, a second end attached to said support frame, and a pivotable break point between said first and second legs; and i. first and second cable means each having a first end fixed to said support frame adjacent said first end thereof and a second end fixed to a different one of said first and second strut members for moving said struts at said pivotable break point causing said legs to pivot to said second position.
Claim 3
Dependent Claim
68 words
The work table of claim 1 including guide means wherein: a. said guide means are attached to said support frame beneath said top surface; and b. said frame extension means is carried by said guide means and moveable therealong between a first position having a substantial portion thereof beneath said top surface and a second position having a substantial portion thereof extending horizontally outward from said top surface.
Claim 4
Dependent Claim
53 words
The work table of claim 2 wherein: a. said support frame has a generally rectangular shape in a plane parallel to said horizontal top surface including oppositely disposed first and second ends; and b. said frame extension means extends outwardly from said first end of said rectangular-shaped support frame in said second position.
Claim 5
Dependent Claim
41 words
