Legrest Or Footrest Interconnected To Move Relative To Bottom And Concurrent With Bottom Or Back Patents (Class 297/68)
  • Patent number: 6945596
    Abstract: A reclining chair, which has a back and a footrest both angularly displaceable relative to a seat simultaneously, is equipped with an adjusting mechanism, which includes a shaft, a pedal secured to one end of the shaft, a pushing member secured to the other end of the shaft, a fixed pin, and a locking rod; the locking rod is pivoted to the back at an upper end, and is right opposite the pushing member at a lower portion; the locking rod has engaging gaps on a rear edge for selective engagement with the pin; a spring is used for biasing the locking rod such that the locking rod can normally engage the pin at the gaps; thus, the footrest can be adjusted together with the back when the pedal is depressed for making the pushing member push the locking rod forwards such that the locking rod disengages the pin.

  • Patent number: 6855098
    Abstract: An exercise and rehabilitation chair includes a framework having lower frame members, pivotal front legs, and elongate rear legs. The chair includes a seat assembly having a seat bottom and seat back and upper arms, each upper arm being pivotally coupled at one end to a generally upstanding support arm and at an opposed end to a front leg. Bearing housings pivotally connect corresponding support arms and rear legs and establish a fulcrum about which the seat assembly may rotate. The bearing housings may be slidably positioned longitudinally along corresponding support arms and rear legs using pin fasteners or, alternatively, using motorized gear assemblies. The displacement of the fulcrum relative to a user's hips is adjustable for regulating the resistance of chair operation. A foot assembly is pivotally coupled to the front legs. All pivotal connections correspond anatomically to a user's joints for low joint stress and low-resistance exercise.

  • Patent number: 6089652
    Abstract: A fish fighting apparatus for assisting an angler in the capture of large hooked fish. The fish fighting apparatus includes a rotational platform that attaches to a fish fighting chair for use by an angler in pulling a hooked fish into a boat using a fishing rod. The platform includes a base having a top surface and a bottom surface and an attachment plate which attaches said platform to the deck of the boat. The base is rotatably connected to the attachment plate via the bottom surface of the base. The base can be rotated substantially independent of the pull on the fishing rod since the position of the point of rotation of the chair attached to the platform is offset from the point of rotation of the base of the platform. An accessory attachment bar is mounted to the attachment plate and a vertical chair support member is pivotally fastened to the accessory attachment bar allowing a slidable seat to pivot back and forth.

  • Patent number: 6070935
    Abstract: A piece of furniture has a generally stationary main part, an actuator in the main part, and a movable part that is pivotal on the main part generally about an axis. An actuating assembly for the movable part has an elongated one-piece operating bar formed of a single piece of tubing having a central portion extending along the axis and a pair of U-shaped end portions each having an inner arm forming a continuation of a respective outer end of the central portion and an outer arm extending across the axis, projecting radially therefrom, and provided with mounting formations. The portions and arms all are generally coplanar. Pivot pins fixed on the main part engage through the outer arms at the axis for pivoting of the operating bar on the main frame about the axis. Respective fittings secured to the mounting formations of the outer arms are connected to the movable part and a crank arm fixed on the central portion and extending radially therefrom is operatively connected to the actuator in the main part.

  • Patent number: 5800009
    Abstract: A reclining chair, including a leg-rest-operated reciprocating latch for releasably retaining the leg rest. The leg rest linkage is retracted when the occupant applies force to the leg rest in a generally rearward direction until the parts of the latch engage one another to retain the leg rest in the retracted position. The latch is released by a second, momentary application of force in the same direction, enabling the leg rest to move to an extended position. An occupant-weight-actuated lock member prevents the latch from being released unless the chair is occupied by a person weighing more than a minimum amount. The lock member includes an adjustment device by which the minimum occupant weight required to permit operation of the chair can be varied.
