Disclosed is a foldable table whose table plate may be readily and easily folded down with a single operation of a knob and restored back to its horizontal position simply by lifting up the table plate as a natural motion of bringing the table plate to such a position through the use of a pair of cams mounted on a table plate bracket. One of the cams keeps the table plate in its horizontal position by engaging a stopper pin fixed from a support while the other cam releasably engages the first cam to the engaged state.

A support surface movable between two positions, comprising: means for movably supporting said support surface between two positions; an engagement pin fixedly mounted upon said means supporting said support surface; a first latching member pivotably mounted upon said support surface, and including first and second notched portions, said first notched portion being engageable with said engagement pin so as to retain said support surface in a first one of said two positions; a second latching member, fixedly secured directly upon a shaft rotatably mounted within said support surface, having a projection engageable with said second notched portion of said first latching member whereby said second latching member is disposed in a locked position so as to retain said first latching member in engagement with said engagement pin; spring-biasing means for interconnecting said first and second latching members together; and manually accessible lever means, fixedly connected directly to said shaft upon which said second latching member is fixedly secured, for rotating said shaft and said second latching member from said locked position to a release position so as to permit said first latching member to be disengaged from said engagement pin under the influence of said spring-biasing means whereby said support surface is able to be moved from said first one of said two positions to a second one of said two positions.
