New description: 【New technical field of the invention】 This creation is about the design of a folding chair frame with improved structure and spacing expansion device for the back of the frame, and the folding of the chair on the forefoot. The vesti has a [previous technique] to connect the two folding chairs. The back-profile 'back plate body a has an arc-shaped body surface ί in the 'eye wheel 1 (the figure is not $, the back plate body A upper edge table, combined with the inner edge of the upper portion of the soft frame B, so that the back face faces folded Relying on the forefoot, the side Ai is quite thin, and the screw (3) has a long-term screwing force. The m is again, which may cause the entire backboard to be placed on the front leg of the female B. The spacing is often overlapped into an early arrangement, but to retain The appropriate fingerboard for the seat is t. The manufacturer has improved the above problem and the iron bar 3 is placed on the bilateral side of the mother Zhangjiao 5® chair. A ring is set separately for the above: The iron rod D of the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The folding chairs can be neatly arranged in a plurality of columns. Although this together, the folding and ίί丰 can be arranged in an irregular manner, but since each folding chair needs to be connected in a limited 'Special benefit two (four) to take the deletion I often feel the space M341462 f new content] <The technical problem of the 2 solution is not solved. The problem is that the combination structure of the improved folding chair back panel enables the back panel to be firmly bonded to the inner edge of the front leg. The second problem solved is to improve the fastening device of the folding chair of the type, ^ : 重 重 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠 折叠The technical means of solving the problem ❿ 赤 为 为 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Therefore, after forming a solid Z bracket on the surface of the forefoot, a plurality of locks are placed on the back frame of the back frame = ' and the screw is screwed down to the upper edge of the seat back. The expansion is larger than the front end surface, each side; J is; = two, the surface and the two sides, the rear end faces are arranged by the chair and the cymbal at the same intersection angle.

"The effect on the prior art" between the back of the chair and the front domain Set the simple back frame, simply let the duck directly wear the lock M341462. When the upper edge of the moon can be used, it may cause the upper edge of the back of the chair to be deformed. ^ ^ Increase the locking area, so that it can be shot on the Wei Wei chair. ^ The expansion provided by this creation The spacing device is combined. The viewer's vision will not be hindered.

The main body 6 has a front end surface 61, a rear end surface 62, and a second surface 63, 64. The rear end surface 62 is larger than the front end surface 61, and each side surface 63. The rear end face 62 is inclined obliquely toward the rhythm end face 61' between the two side faces 63, 64 to form an angle α (see the eleventh figure). There is a card edge 631 on the side 63, and a hole 632 is formed under the card edge 631. The hole 632 is provided with a locking component 65. The locking component 65 includes a plug 651 which is disposed through the hole 632. And a sleeve 652 disposed on the plug 651 for increasing the locking area, and a nut 653 for screwing on the plug 651; opening on the side 64: the button hole 641 has a necking The end, so the buttonhole 641 _ is approximately an inverted embossed shape.

When assembling, the buckle hole 7 of the plate body 7 on the front leg of a folding chair is made so that the head of the plug 651 slides first/the neck end of the 71, and the head of the plug 651 is the edge plate body 7 of the buckled hole 71. The broadcast, private 2 off the board 7. Then, the hole 632 of the body 6 is correspondingly fitted to the plug 651, and the card edge 631 of the second holding η S i protrudes into the button hole 71 and is clamped to the back of the plate body 7 and the front leg frame 653. The surface of the body 6 attached to the inner side of the hole 632 is loosely fitted until it abuts against the spacer 652, so that the end surface of the plug 651 abuts against the side of the fixed body 6 to prevent the body 6 from being rotationally displaced. The second f is passed through the buttonhole 64 of the body 6 and slides into the love of the buttonhole (4) to fix the other side of the body 6. According to the above embodiment, the side surface 63' of the second expansion charging device 9 can be connected to the side of the side 64' of the second folding chair. The performance makes the number of positions to be transposed and the multiple folding chairs are connected, and the angle is not in the picture. The picture has the front and rear two rows of folding chairs, mentioned in the front section, because the back of the M341462 folding chair There are two folding chairs connected to each other, in two types of trajectories. The number of expansion spacing devices 9 are connected, and the 俾 arrangement forms an arc to look ahead, the field of view is the same as the audience sitting in the middle position; Control the number of folding chairs in front and back, so that the front and back rows are folded b, '9' so that the front row of viewers will not block the view of the rear audience. This writer is only to explain the better implementation of this creation. For example, it is not an attempt to restrict the form of Guanyin. Therefore, any modification or change made under the same creative spirit should still be included in the protection of this creative intention.
