A foldable frame support device for supporting a top plate used for furniture, includes two support braces disposed to prop releasably and respectively two support legs in a straddling position. Each support brace includes a spring-biased locking lever with a locking end to snap an anchoring end of a respective strut member. The strut member has a pivot end connected pivotally to a respective support leg so as to be swingable to permit placement of the support leg in a folded position upon actuating the locking lever to release the anchoring end of the strut member.

1. A foldable frame support device for supporting a top plate used for furniture, said device comprising:a pair of support legs spaced apart from each other in a longitudinal direction, each of said support legs having a top end formed with a pivot shaft which extends in a transverse direction transverse to the longitudinal direction and which has front and rear end segments opposite to each other in the transverse direction, each of said support legs further. having a bottom end adapted to be placed on a ground surface, and an intermediate portion disposed between said top and bottom ends; a pair of side rods extending in the longitudinal direction and spaced apart from each other in the transverse direction, each of said side rods having two opposite ends connected pivotally and respectively to a respective pair of said front and rear end segments of said pivot shafts about first and second axes which are parallel to each other, such that said support legs are turnable relative to said side rods about the first and second axes between a folded position, where said bottom ends of said support legs are closer to said side rods, and a straddling position, where said bottom ends of said support legs are remote from said side rods; and a pair of support braces disposed to prop releasably and respectively said support legs in the straddling position, each of said support braces including a cross shaft extending.in the transverse direction and disposed inboard to said pivot shaft of the respective one of said support legs in the longitudinal direction, said cross shaft having two connected ends connected respectively to said side rods, and an intermediate segment disposed therebetween, an anchored member having an upper secured portion secured on said intermediate segment of said cross shaft, and a lower anchored portion extending downwardly from said upper secured portion and away from said cross shaft to terminate at a lower wall, said lower wall defining an anchored concavity which extends toward said upper secured portion, a strut member having a pivot end pivotally connected to said intermediate portion of a respective one of said support legs, and an anchoring end disposed opposite to said pivot end and swingable relative to said intermediate portion about a third axis parallel to the first axis between an engaged position, where said anchoring end engages said anchored concavity so as to prop the respective one of said support legs in the straddling position, and a disengaged position, where said anchoring end disengages from said anchored concavity so as to permit placement of the respective one of said support legs in the folded position, a locking lever extending in the longitudinal direction, and having a fulcrum connected pivotally to said anchored member about a pivot axis in the transverse direction, a locking end disposed at one side of said fulcrum and extending in said anchoring concavity to snap said anchoring end when said anchoring end is in the engaged position, and an actuated end disposed at the other side of said fulcrum and turnable about the pivot axis between a first position, where said locking end snaps said anchoring end, and a second position, where said locking end releases said anchoring end, and a biasing member disposed to bias said actuated end to the first position.
