  • Patent number: 5970538
    Abstract: A pantographic support control mechanism (10) for use with furniture includes one or more pantographic linkages (16). The or each linkage (16) is mounted between a forward end (104) and a rearward end (26, 106). Extension of the linkage(s) (16) causes relative movement of the forward and rearward ends (104) (26, 106) away from each other whereas contraction of the linkage(s) (16) causes relative movement of the forward and rearward ends (104) (26, 106) towards each other. One or more support means (14) are pivotally mounted with respect to and at or near respectively one or more of the pantographic linkages (16). One or more corresponding urging means (12) are arranged to act between a pantographic linkage (16) and a respective support means (14) in a manner such that extension of the or each linkage (16) causes the or each urging means (12) to respectively act on its respective support means (14) to cause it to pivot from an inoperative position to an operative position.

Each of the pairs of support links comprises a support leg which adjustably connects the front and rear frame plates. A plurality of arms are connected to the upper end of the support links and a plurality of mounting plates are positioned upon the support arms for receiving a mattress or other bed surface. The frame plates can be provided with rollers for facilitating movement of the bed and a stopper can be provided for preventing movement of the rollers. If desired, the mounting plates can be placed upon rather than connected to the arms and can be formed so that the widths of adjacent pairs of the plates increase in the longitudinal direction of the bed.
