Patent number: 4906045Abstract: A chair control for a pedestal chair having a knee-tilt seat. An elastomeric torsion spring is offset rearwardly from the tilting axis of the seat. The seat and torsion spring are operatively connected by a cam surface and a cam follower which effectively reduce the restoring force exerted by the torsion spring against the seat as the rearward tilt of the seat increases. A mechanism to adjust the initial restoring torque of the torsion spring provides a large angular twist of the torsion spring with a minimum linear movement of the mechanism. The chair control provides the chair seat with a less than conventional seat angle relative to the horizontal when the chair is unoccupied. A mechanism is provided to enable the occupant to adjust the chair seat to a more conventional seat angle in its unoccupied condition.Type: GrantFiled: March 20, 1989Date of Patent: March 6, 1990Assignee: The Shaw-Walker CompanyInventor: William K. Hofman

Patent number: 4904018Abstract: A foldable seat device having diagonal side legs for support of a flexible sheet seat along its rearward and forward portions; and although legs extending from the rearward portion of the seat are conventionally continuous to their feet, the legs extending from the forward portion of the seat are of two discrete and non-connected portions.Of those legs, the adjacent ends of the lower rearward leg portion, and of the upper forward leg portion, are pivotally connected to the other legs at spaced points therealong; and those unconnected leg portions are pivotally movable independently of one another, permitting a seat-open condition of the seat even though the rear seat-feet may be then retracted to permit a support of the seat in a partially folded condition which permits a use of the seat while the device is leaning against a tree for user comfort.Type: GrantFiled: October 20, 1988Date of Patent: February 27, 1990Inventor: Noah W.

Patent number: 4904020Abstract: A chair comprises a seat (6), a back (7) and a frame (2, 3, 4, 5). In order to give the user a comfortable opportunity to change his position during the use of the chair, the positions of both the chair (6) and the back (7) are readjustable with respect to the frame. The angular position of the seat is readjustable from a first position to a more backward inclined position and the back (7) is readjustable from a first position to a more backwardly inclined position.

Patent number: 4898103Abstract: A desk has a vertically adjustable top and at least one vertical guide member movable upwardly and downwardly on a support or frame. A spring leg is disposed between the frame and vertically adjustable desk components. The spring leg is pivoted at one end to a guide member and its other end is braced against a curved rail. The braced end is movable on the rail and lockable in positions corresponding to accommodate various loads on the desk top. The curve of the rail is chosen so that in any position of the braced spring end, the vertical components of force acting on the guide member are equal, at least in two opposite end positions of the desk top. This results in equilibrium in each vertical position for every load on the desk top, after the spring leg has been adjusted.Type: GrantFiled: June 15, 1988Date of Patent: February 6, 1990Assignees: Willy Fleischer, Metallwarenfabrik GmbH & Co.

Patent number: 4887537Abstract: A storage container such as a bin or tank is received on a pallet having a shock isolation arrangement which will reduce damage to the container and the goods contained therein. The pallet is formed with a hollow square frame having rolled or otherwise formed edges arranged to retain rubber-like hose sections which engage the container sides adjacent each container corner and absorb horizontal plane shock as well as some vertical plane shock. Once the rubber hose sections are inserted in the pallet frame while the container is in position thereon, the sections will hold the frame and the container together so that they may be transported as a unitary assembly. The rubber-like hoses will continue to isolate the container from impacts transmitted to the pallet in typical handling operations. The assembly may be readily moved by a forklift or other similar equipment.Type: GrantFiled: February 4, 1985Date of Patent: December 19, 1989Assignee: General Motors CorporationInventor: George E.
