摘要:
The specification discloses a chair having a seat, back and wire rod frame. The frame includes five wire rods and a stretcher welded together to provide an integral seat support, leg assembly and back support. Three of the five rods are welded together in endwise abutment to provide the frame with a continuous, uninterrupted appearance. The two wire rods at the rear extend upwardly forming rear legs, then diverge inwardly along the rear of the seat. They meet and extend upwardly together, rigidly joined to form an upright portion. The rods then diverge outwardly and upwardly to provide a U-shaped back support. The seat includes downwardly depending tabs at either side which mate with flanges on the sides of the seat support portion of the frame. The front of the seat comprises a lip which curls over a front rod of the seat support. The chair rests on four glides, all of which have fastening intelligence such that the chairs of this invention can be ganged together. The glides on one runner have facing fastening intelligence while those on the other runner have fastening intelligence facing away from one another, such that fore and aft and lateral movements of joined chairs are eliminated.
