  • Patent number: 4261266
    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.

  • Patent number: 4109589
    Abstract: A glass top table has pivotally supported end leaves mounted between spaced side frames for movement between an inwardly projecting storage position and an outwardly projecting use position. Each side frame has an upper frame member and a pair of legs projecting downwardly from opposite ends of its upper frame member. A glass table top extends laterally between the upper frame members and is located above the end leaves in their storage position and in alignment therewith in the use position. Each end leaf includes a peripheral rectangular frame which is elongated in a lateral direction and a glass leaf secured to the rectangular frame. A pair of support frame members extend laterally between the upper members of the side frames and are located adjacent the end leaf frames in the storage position thereof so as to provide an aesthetically appealing appearance.

  • Patent number: 3974782
    Abstract: An extendable table of the disclosure includes an extendable frame having laterally spaced slide assemblies extending between opposite ends thereof so as to be capable of supporting table tops of different lengths. Each slide assembly includes a pair of hollow female beams projecting from opposite ends of the frame and having open ends that receive the opposite ends of a male support member which aligns and slidably interconnects the beams with each other in cooperation with an improved pad arrangement. The support member is maintained within the beams by certain pads of the arrangement that include securement portions extending downwardly through securement openings in the open ends of the beams for welding to the bottom walls of the beams. The support member is positioned in a spaced relationship with respect to the cross-sections of the beams to permit sliding movement therebetween despite variance in the size of these components along their axial lengths.
