Description
The utility model relates to a kind of faldstool, particularly can fold and the double folded formula chair of seat board upset.
The faldstool of selling on the existing market has two kinds, and a kind of is radial type, and another kind is a chute-type.The radial type joint-stool is to utilize stamping parts, is connected by rivet or screw, forms the linkage of radial type, realizes the folding of chair and seat board upset.But this chair is because number of spare parts is many, and stamping parts rigidity is low, and stamping parts and rivet or screw are in use stressed big, easily causes distortion and wearing and tearing, uses inefficacy person more for a long time.The chute-type folding seat is made up of preceding pipe, back of the body pipe, seat board, seat bar and axle etc., open an elongated slot at back of the body pipe middle part towards seat board one side, the seat rod end head that is fixed in the seat board is inserted in this groove, when seat board is swayed, drive seat bar upper and lower slip and back of the body pipe, preceding pipe in this groove and sway, realize the folding of chair and seat board upset.The back of the body pipe sidewall of groove bottom limits seat bar position, and supports chair when user mode, seat board and human body or other weight of heavy.Though this folding seat number of spare parts is few, but owing to the overall aesthetic that has destroyed chair at back of the body pipe middle part cutting elongated groove, and cause the psychological sense of insecurity of user, become the obstacle that chair is sold, simultaneously, rigidity, the intensity of back of the body pipe also descend, the fluting operation is many, and efficient is low, because of fluting residues in the burr of groove edge and the ripple of formation, make the folding and seat board upset inconvenience of chair, and may block.
It is few that the purpose of this utility model provides a kind of number of spare parts that relatively connects the formula folding seat, avoids chute-type folding seat cutting elongated groove on back of the body pipe, keeps the complete of back of the body pipe, enhances productivity the joint-stool of good looking appearance.
Task of the present utility model is finished like this: on left and right two back of the body pipes slide block that slides along back of the body tube outer surface is arranged respectively, slide block has a hole towards seat board one side, seat rod end head is inserted in this hole, the seat bar is connected on the seat board, when seat board is swayed, be connected in seat bar on the seat board drive slide block along the upper and lower slip of back of the body tube outer surface and before pipe, back of the body pipe sway, realize the folding of chair and seat board upset.The back of the body pipe outer wall of slide block below has limited block or back of the body pipe that step is arranged, and when chair is user mode, withstands the weight of objects such as slide block and supporting slide block, seat board, human body.Slide block along the hole wall in the hole that back of the body tube outer surface slides be sealing or otch arranged.Slide block is on the hole wall in the hole of sliding along back of the body tube outer surface or on the protuberance of hole wall towards the hole of seat board one side, the hole wall in this hole be sealing or otch arranged, this hole and hole along the slip of back of the body tube outer surface be communicate or do not communicate.Be to reduce the wearing and tearing of slide block and back of the body pipe, at slide block along adding the lining of soft material or carry out surface treatment in the hole that back of the body tube outer surface slides.When with slide block double as decoration, there is pattern on its surface or the decoration plating coating is arranged.Seat rod end head also can not be to be inserted in slide block in the hole of seat board one side, but is connected towards seat board one side with slide block with rivet or screw.
The utility model is not owing to there is more hinged part, prolonged service life, noting be used in back of the body pipe goes up fluting and has kept the complete of back of the body pipe, intensity, rigidity have been improved, increased aesthetic feeling, slide block easily guarantees with the quality of fit of back of the body pipe, seat bar, makes the folding of chair and seat board upset convenient, slide block can adopt die casting or moulding, the production efficiency height.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is the front view that the utility model is folded state.
Fig. 2 is the amplification profile of Fig. 1 along the A-A line.
