Appl. No.:

6/869190

Inventors:

David L. Rowland - New York NY

International Classification:

A47C 304

US Classification:

297239

Abstract:

A stacking armchair having two symmetrical front frame members, each having a bottom rail portion, a front leg portions, and a seat side rail portion, a rear connecting member connecting together the rear ends of the side frame portion, a front brace across the front leg portions. All these are made from thin rod stock. The rear of each bottom rail portion has a turned-up generally vertical terminal portion, and the rear connecting member extends out beyond the seat side rail portions. Two rear leg members are made of rod stock greater in thickness, strength, and stiffness than the rod stock from which the front frame members are made. The rear leg members are butt-welded at their lower ends to the tops of the terminal portions and are also welded to the ends of the rear connecting member. A seat is secured to the side rail portions and to the rear connecting member, and a back is secured to upper portions of the rear leg members. At its upper end each rear leg member is bent to provide a short, straight, outwardly extending horizontal portion and then bent again to provide an arm-support portion parallel to the side rail portion but outboard from it.

Appl. No.:

International Classification:

US Classification:

297445

Abstract:

A seat-back unit for a chair utilizes pre-flexed sheets of sinuous spring wire material connected to relatively rigid side support members which afford flexibility, but provide a frame for the unit. The two L-shaped side support members are held apart by a rigid cross stretcher member positioned in the seat portion, near the back. The seat-back unit is connected to a chair frame at only four points in a "cradling" arrangement, by means of a pair of hooks extending back from the tops of the relatively rigid members, received in slots of the chair frame, and by bolted connections of the relatively rigid members at the front of the seat portion to the chair frame. The seat-back unit, and particularly the relatively rigid frame members, are put into a pre-stressed condition as the seat portion is connected to the chair frame. Covering material, which may be removable, is positioned over the seat-back unit. A simple chair frame structure is preferably used, with an X-shaped bracing configuration at the bottom and four upright legs.

Inventors:

David L. Rowland - New York NY

International Classification:

A47C 304

US Classification:

297239

Abstract:

A stacking chair and a metal chair frame therefor. One frame member has an U-shaped, horizontal portion and a pair of vertical front legs. The horizontal portion comprises a lateral rear portion and horizontal side portions that lie generally parallel to each other, but diverge somewhat from rear to front. Each of two flanged frame juncture members has a horizontal top and a pair of vertical side flanges; the top has a pair of horizontal edges and each side has a pair of vertical edges. One horizontal edge and two vertical edges of each are welded to the frame side portions adjacent the rear lateral portion. Rear legs with integral back-support portions are welded to the other horizontal and vertical edges, so that they are spaced apart from each other farther than are the front legs. The rear legs may be two separate members or there may be a single continuous member including both legs and joined at the top. A seat (preferably non-rigid, resilient) bridges and is secured to the frame side portions and urges them toward a truly parallel relationship, and a similar back bridges and is secured to the back-support portions and, if they diverge, urges them toward a truly parallel relationship.
