61 Pull rod-type foldable chair structure US10175649 2002-06-19 US06669281B1 2003-12-30 Tsung-Chieh Huang
Pull rod-type foldable chair structure. A pull rod is telescopically inserted in the top end of the rear chair leg and pivotally connected with the front chair leg. When folding or unfolding the rear chair leg, the pull rod provides a pneumatic buffing effect. Two J-shaped lateral support boards are previously mounted on inner sides of the chair frame, whereby the seat can be directly assembled with the support boards by insertion. The back is assembled with the upper end of the front chair leg by engaging members. Therefore, the chair frame, the seat and the back can be quickly assembled. The transverse beam of the chair leg is equipped with elastic ground-contacting blocks. Therefore, the chair can be used on any floorboard made of any material such as wooden, plastic and stone floorboards. The ground-contacting block will not scrape the floorboard and the chair can be more stably placed on the ground.
62 Slide rail-type metal foldable chair US10175632 2002-06-19 US20030234562A1 2003-12-25 Tsung-Chieh Huang
Slide rail-type metal foldable chair. The front chair leg is pivotally connected with outer side of the rear chair leg at a pivot point. The inner side of the front chair leg is formed with a slide rail. A slide rail washer is laid on the opening of the slide rail. A slide magazine is up and down slidably disposed in the slide rail of the front chair leg. The bottom end of the slide magazine is formed with a fitting hole. A rear pivot shaft of the seat for pivotally connecting with the front chair leg is fitted through the fitting hole and located therein. The inner wall of top end of the rear chair leg is formed with a pivot hole. The front pivot shaft of the seat is fitted through the pivot hole and located therein by a retainer ring. Therefore, the pivoted sections of the seat and the front and rear chair legs are all hidden and only the pivot point of the front and rear chair legs is exposed. The foldable chair is light and can be easily operated. The foldable chair can be folded into a plane state without clamping a user's hand.
63 Gate-fold chair US266523 1999-03-11 US6015185A 2000-01-18 Steven A. Buono
A folding chair with increased stability having side legs comprising rear portions pivotably connected to lower portions of the rear legs and extending at an acute angle from the rear legs toward the curved portions, and forward portions extending at an acute angle from the curved portions. The seat rotates about a seat rod, and the side legs pivot about the rear legs at a point near the bottom of the rear legs, to provide a chair that in folded position is relatively flat for ease of storage and transportation, and that in unfolded position provides a more stable chair.

A folding chair includes two front legs (10, 12) which are rigidly connected at their lower ends with rearwardly oriented supporting arms (14, 16). Arm rests (24, 26) are pivotally connected with the upper ends of the legs (10, 12), and a seat plate (18) is pivotally attached at a lower point of the legs. The rear ends of the seat plate (18) and of the arm rests (24, 26) are connected by means of struts (38, 40) which are articulated on both sides. The upper ends of the legs (10, 12), the arm rests (24, 26), the rear struts (38, 40) and the seat plate (18) form a parallelogram assembly on either side of the chair so as to make it possible to fold the folding chair together into an essentially vertical position by raising the back rest.
