Abstract
An improved gliding chair system for use in residential and commercial applications which provides facilitated gliding movement over non-smooth surfaces, such as carpets, without the need for area chair mats. Lever assemblies attached to the chairs legs automatically distribute the weight of the chair and its user as desired to a greater number of support locations, and in cooperation with various gliding devices, imparts a facilitated gliding action on such surfaces.
Claims13
An improved gliding chair system comprising:
- elevated sitting means for receiving a user's body;
- chair support means attached to and cooperating with the lower end of said sitting means for providing support and means for mobility to said gliding chair system,
- said chair support means comprising a plurality of extended leg members,
- said chair support means further comprising one or more double-action lever means rotatably connected for movement in a vertical plane at a fulcrum point located a desired distance along one or more of said plurality of extended leg members respectively,
- each of said lever means maintained in a fixed protruding position relative to said leg member so as to be in substantial alignment with said respective leg member whereby rotative movement of said lever means relative to said respective leg member in a substantially horizontal plane is precluded,
- each of said one or more double-action lever means having outer gliding means attached by glide attachment means proximate to a first end of said lever means and inner gliding means cooperating with a second end of said lever means, and
- each of said one or more double-action lever means rotating about said fulcrum connection in said extended leg member so as to distribute the weight of said user's body and said chair system through both said inner and outer gliding means, thereby reducing the force exerted by said user and chair at any one point on a surface and facilitating the gliding of said chair over said surface.

- each of said one or more double-action lever means rotating about said fulcrum connection in said extended leg member so as to distribute the weight of said user's body and said chair system through both said inner and outer gliding means, thereby reducing the force extended by said user and chair at any one point on a surface and facilitating the gliding of said chair over said surface;
- said inner gliding means comprising a common master glide attached to said chair support means so as to telescope downwardly therefrom;
- said master glide having a substantially discshaped curvilinear lower surface;
- said master glide having an upper surface extending radially to a position directly below said second ends of said one or more lever means respectively;
- and
- said one or more lever means collectively distributing a portion of said chair and user weight through said respective second ends to said common master glide which, in turn, telescopes downwardly to distribute said weight to said surface.
