Wall proximity chairs and hardware therefor

Abstract

This invention adds a stabilizing system to the chair disclosed in our copending application Ser. No. 618,954, filed Oct. 2, 1975, and minimizes swaying side to side, and thereby maintaining the rigidity of the chair. The stabilizing system comprises a pair of paralleled base plates attached to front and rear cross-rails supported on the floor. Arm mounting members are attached to the left and right side arms of the chair, respectively. Friction reducing buttons on said arm mounting members movably contact said base plates. At least one of said buttons is adjustable to ensure retaining said chair against swaying sideways. A button at each side of the chair, is attached to one link of the arm rest suspension linkage, to slidably contact another link of the suspension linkage, to also aid in preventing side sway of the chair. The cross-rails extend beyond the base plates and beyond the inner surfaces of the side arms of the chair. The cross-rails can extend to the outer surfaces of the side arms, with supporting pads or glides mounted on the ends of the rails to increase stability of the chair, particularly against tilting sideways if excessive weight is imposed on one side of the chair. The rear cross-rail is vertical while the front cross-rail is horizontal, thereby giving rigidity to the parallel base plates. The base plates are supported on the cross-rails and the rest of the chair is supported on the base plates. Parts of the base plates are pushed out where the buttons contact the base plates in the upright position of the chair, for increased rigidity in said upright position. Coil springs are employed to help ensure keeping the leg rest retracted in upright position of the chair.
