ABSTRACT:
A table leg locking mechanism that secures the legs of a table into operative position when a retaining member of the locking mechanism is engaged, with said retaining member normally being biased into this engaging disposition through the agency of a spring; the locking mechanism includes a cross bar that secures to the table leg(s), a pair of housings having the cross bar pivotally mounted therethrough, with one of said housings incorporating a pair of sleeves, one of the sleeves being rigidly secured internally to the housing, and the other sleeve being rigidly fixed to the cross bar. The retaining member includes a wedging member(s) projecting from one of the sleeves, with a complementary groove(s) provided in the other sleeve, whereby the pivoting of the leg into its operative position allows the wedging member to become wedged within the groove for fixing the table leg into a supportive position.
