Abstract
Abstract A portable work or display table comprising a case having a bottom wall and side walls which mutually define a generally rectangular compartment, a cover being hinged to one of the side walls and closing the compartment. The bottom wall has a pair of elongated spaced, parallel openings formed therein respectively communicating with the compartment. First and second pairs of leg members are provided with means for pivotally mounting the leg members of each pair respectively adjacent their upper ends on a wall of the case, each pair of leg members being respectively pivotally mounted adjacent opposite ends of respective ones of the openings so that each pair of leg members is pivotally movable through the respective opening between a stored position in the compartment with one leg of the pair substantially closing the respective opening and being generally flush with the bottom wall, and an extended position for supporting the case as a table.

A portable work or display table comprising a case having a bottom wall and side walls mutually defining a generally rectangular compartment, a cover hinged to one of said side walls for closing said compartment, said bottom wall having a pair of elongated, spaced, parallel slots formed therein respectively communicating with said compartment and respectively parallel with and adjacent opposite ones of side wall, first and second pairs of leg members each having upper and lower ends, means for pivotally mounting said first pair of leg members respectively adjacent their upper ends on one of said opposite side walls, the legs of said first pair being respectively pivotally mounted adjacent opposite ends of the respective one slot, means for pivotally mounting the second pair of leg members respectively adjacent their upper ends on the other of said opposite side walls, the legs of said second pair being respectively pivotally mounted adjacent opposite ends of the other slot, the leg members of each pair being pivotally movable through the respective slot between a stored position in said compartment with one leg of the pair substantially closing the respective slot and being generally flush with said bottom wall, and an extended position for supporting said case as a table, the leg members of each pair in the stored position thereof extending in opposite directions and being in parallel, vertically overlapped relation with respect to said cover and bottom wall, said mounting means for each said leg member comprising a pin slidably received in a slot in the respective one of said opposite side walls, each of said last-named slots being generally perpendicular to said bottom wall and having lower and upper ends, each of said pins being adjacent said lower end of the respective last-named slot in the stored position and adjacent the upper end in the extended position of the respective leg member, said case having four parallel, vertical extending openings formed therein, said openings being respectively adjacent the ends of said first-named slots, the upper end of each said last-named slot extending into a respective opening, said upper ends of each of said leg members in the extended position thereof being received in a respective opening and being held thereby against collapse.
Claim 2
Dependent Claim
372 words
A portable work or display table comprising a case having a bottom wall and side walls mutually defining a generally rectangular compartment, a cover hinged to one of said side walls for closing said compartment, said bottom wall having a pair of elongated, spaced, parallel slots formed therein respectively communicating with said compartment and respectively parallel with and adjacent opposite ones of side wall, first and second pairs of leg members each having upper and lower ends, means for pivotally mounting said first pair of leg members respectively adjacent their upper ends on one of said opposite side walls, the legs of said first pair being respectively pivotally mounted adjacent opposite ends of the respective one slot, means for pivotally mounting the second pair of leg members respectively adjacent their upper ends on the other of said opposite side walls, the legs of said second pair being respectively pivotally mounted adjacent opposite ends of the other slot, the leg members of each pair being pivotally movable through the respective slot between a stored position in said compartment with one leg of the pair substantially closing the respective slot and being generally flush with said bottom wall, and an extended position for supporting said case as a table, the leg members of each pair in the stored position thereof extending in opposite directions and being in parallel, vertically overlapped relation with respect to said cover and bottom wall, said mounting means for each said leg member comprising a pin slidably received in a slot in the respective one of said opposite side walls, each of said last-named slots being generally perpendicular to said bottom wall and having lower and upper ends, each of said pins being adjacent said lower end of the respective last-named slot in the stored position and adjacent the upper end in the extended position of the respective leg member, said case having four parallel, vertical extending openings formed therein, said openings being respectively adjacent the ends of said first-named slots, the upper end of each said last-named slot extending into a respective opening, said upper ends of each of said leg members in the extended position thereof being received in a respective opening and being held thereby against collapse.
Claim 3
Dependent Claim
