    Patent number: 5615765
    Abstract: A container for the reception of objects, and especially a spectacles case, is proposed, having two mutually opposing, circular-segment-shaped half-shells for the creation of a hollow body.

  • Synchronous adjusting device for office chairs or the like
    Patent number: 5366274
    Abstract: A synchronous adjusting device for a chair is provided where the restoring movement of a back part is effected as a function of the weight of the user, a restoring moment occurring with the increase in inclination of the backrest. For this purpose, the back part is mounted rotatably relative to the seat part at a distance in height. The leaning force of the user at the back leaning point is counteracted by a restoring force in the lower region of the back part as a result of the articulated connection between the seat part and the back part.

  • Synchronous adjusting device for office chairs or the like
    Patent number: 5251958
    Abstract: A synchronous adjusting device is proposed as a chair mechanism for office chairs, seat furniture or the like, which is constructed extremely simply and with few mechanical components and which, if appropriate, can do without additional force accumulators. At the same time, the restoring movement of the back part will take place as a function of the weight of the user, a restoring moment occurring with the increase in inclination of the backrest. For this, the back part (7) is mounted rotatably relative to the seat part (5) at a distance in height. The leaning force (9) of the user at the back leaning point (10) is counteracted by a restoring force in the lower region of the back part as a result of the articulated connection between the seat part and the back part (7).

  • Chairs
    Patent number: 4130263
    Abstract: A pedestal stool is disclosed having a base carrying a stem on which a seat portion is supported.The base includes a sand-filled, bulbous, ground-engaging bag or sack to enable the stool to be tilted at any angle and held at that angle by virtue of the change in shape of the sack in response to the resultant flow of sand which produces a new equilibrium position for the stool.
