Abstract
A folding table wherein a top, pivotally coupled to a pair of tubular legs, is also connected by struts to slide members which move within the legs. Latch mechanisms, which are also positioned within the legs, cooperate with the slide members to lock the tabletop in the raised position and a cam-cam follower arrangement couples the latches to the slide members for the purpose of limiting the degree of motion of the top upon initial unlatching. The table is also characterized by a base including retractable casters which are operated by the slide members.
Claims13
A folding table comprising:
- a pair of spaced apart legs, said legs being oriented generally vertically and being substantially parallel to one another, said legs each including a tubular member, said tubular members being provided with elongated slots, the slots in said legs being in facing relationship;
- tabletop means;
- base means, said base means being affixed to said legs adjacent the lower ends thereof, said base means including a pair of substantially parallel U-shaped members, each of said base means U-shaped members being affixed intermediate its length to the lower end of a tubular member of one of said legs, the openings of said U-shaped base means members facing downwardly, said base means further including a rigid foot extending downwardly from each end of each of said U-shaped members;
- a plurality of casters;
- a bar mounted within each of said base means U-shaped members, said bars being oriented generally parallelly with said U-shaped members and having said casters affixed thereto;
- a connecting rod extending upwardly from each of said bars into the tubular members of said legs;
- slide means movable within each of said legs, said slide means each including a projection, said slide means contacting the upper ends of said connecting rods when said tabletop means is moved to the stored position whereby said bars and the casters affixed thereto are urged downwardly to thereby raise said feet from the surface on which the table is supported;
- a pivot pin affixed to each of said slide means, said pivot pins respectively extending through and moving along said facing slots in the tubular members of said legs;
- means joining said tabletop means to said legs, said joining means including at least a first strut extending between each of said pivot pins and said tabletop means, said struts being pivotally attached to said pins and tabletop means whereby said tabletop means may pivot between stored and use positions with movement of said slide means;
- and
- latch means pivotally mounted within each of said legs, said latch means cooperating with said slide means projections to lock said slide means in a first position commensurate with said tabletop means being in the use position.

- means joining said tabletop means to said legs, said joining means including a pivot connection whereby said tabletop means may pivot between stored and use positions;
- base means, said base means being affixed to said legs adjacent the lower ends thereof;
- a plurality of casters;
- caster support means, said caster support means being movable with respect to said base means to raise and lower said casters with respect thereto;
- slide means movable within each of said legs, said slide means cooperating with said caster support means to cause movement thereof, said slide means each including a lock member;
- latch means pivotally mounted within each of said legs, said latch means cooperating with said slide means locking members to lock said slide means in a first position commensurate with said tabletop means being in the use position;
- and
- means for limiting the pivotal movement of said tabletop means upon disengagement of said slide means locking members from said latch means, said motion limiting means including pivotal linkage means extending between said latch means and said slide means.
