Creation instructions (2). The front and back legs of the folding chair are in a cross-pivot connection and are pivotally connected by a support frame and a connecting plate. A pivot hole is provided at the front end of the support frame. ， 中 = Suppose there is a long oval through hole, a gap is opened behind the long oval through hole: and the connecting plate is provided with a pivot hole at each of the front and rear ends, and a convex rod is provided on the middle side to connect the plate pivot Connected to the long oval through hole of the support frame, so that = can move in the oval through hole, the front end of the support frame is pivotally connected to the upper end of the rear leg, and the rear end of the connecting plate is pivotally connected to the middle of the front leg, when folded When the chair is unfolded, the convex bar on the side of the connecting plate is inserted into the gap of the support frame and hooked to prevent the I seat cushion from turning up due to improper sitting posture, avoiding the danger of f < embodiment > ° In order to make your reviewing committee understand the creation, the rest of this article will introduce the content of this creation and the functional benefits it can achieve in detail with the illustrations. As shown in the third figure below, this creation is about a kind of conversion. Improved chair structure, especially the safety of an expandable folding chair The front legs 21 and rear legs 2 2 of the chair are pivoted in a cross-connected manner, and the upper ends of the rear legs 2 2 are pivotally connected by the support frame 2 3 and the connecting plate 2 4, and then pivotally connected to the front. The middle of the support leg 2 1 'makes the front support leg 21 and the rear support leg 2 2 foldable. It is further characterized by: a pivot hole 2 31 is provided at the front end of the support frame 2 3, and A long oval through hole 232, a gap 2 3 3 is opened behind the long oval through hole 2 3 2 and a connecting hole 2 4 1 and 2 4 2 are provided at each of the front and rear ends of the connecting plate 2 4 in the middle A convex rod 2 4 3 'on the side is provided with a pivot hole 2 4 at the front end of the connecting plate 2 4. A rivet 3 1 is riveted to the long oval through hole 2 3 2 of the support frame 2 3 so that The rivet 3 1 can be moved in the oval through hole 2 3 2, the front end of the support frame 2 3 is pivoted to M263845 4. Creation instructions (3) The hole 2 3 1 is riveted to the upper end of the rear leg 2 2 by rivet 3 2 The through hole 2 2 1 is provided, and the pivot hole 2 4 2 at the rear end of the connecting plate 24 is also riveted to the through hole 211 in the middle of the front leg 21 with rivets 3 3. After the seat cushion 40 is installed on the supporting frame 23, please refer to the fourth and fifth figures, open the front feet 11 and the rear feet 12, and press down the seat cushion 40 to make the connection plate The convex rod 243 on the side 24 is inserted into the notch 2 3 3 of the support frame 23 and hooked to prevent the seat cushion 4 from turning up and down due to improper sitting posture to avoid danger. When the convex bar 24 3 on the side of the quick-connecting plate 2 4 is to be inserted into the notch 2 3 3 of the support frame 2 3, the rivet 31 riveted by the pivot hole 241 at the front end of the connecting plate 24 is within the notch 2 3 3 of the support frame 23 With a small amount of displacement, the convex rod 2 4 3 can be smoothly inserted into the notch 2 3 3. The notches 2 3 3 on the supporting frame 2 3 are hook-shaped, and the hook-shaped notches 233 are used to catch the convex rod 243. To sum up, the folding chair structure of this creation is particularly useful for the establishment of a new type of patent. It has not been disclosed before the application, and I would like to ask the Bureau to make a clear observation. The specific embodiments are only the more commonly used embodiments.
