Abstract:
An extensible table (10) has one or more pivotal leaves (11) movable between an upper use position and a lower storage position. Each leaf is pivotally supported by a pair of hinges each of which includes a journal (34) which is connected to the pivotal leaf and is received within a journal block (30) formed in the frame of the table. One hinge of each pair is a positioning hinge and the journal thereof has first and second recesses corresponding to the use position and the storage position, respectively. A locking pin (42) disposed in an aperture extending transversely through the journal block of each positioning hinge and engages one of the recesses in the journal when the pivotal leaf is in one position and engages the other of the recesses when the leaf is in the other of its positions. The locking pin also has a recess formed in its shaft which can be oriented to initially register with one of the recesses on the journal to thereupon permit pivotal movement of the end leaf. The journal is secured in the journal bearing by a retaining clip ( 38) in aligned circumferential grooves in the journal and journal block.
