Abstract
The invention discloses a folding chair structure with no cross bars, which comprises a first inverse-U shape piece as a front leg mechanism, a second inverse-U shape piece as a back leg mechanism, as well as a chair board, wherein the top of the second inverse-U shape piece is pivoted with a front connector and is fixed in the forepart of the chair board through the front connector; the middle or upper middle parts of two front legs of the first inverse-U shape piece are pivoted with a back connector respectively; two back connectors are in sliding connection with two side edges of the chair board respectively in order to ensure that the chair board can turn over and change position around the two front legs when sliding relative to the back connectors; and the middle parts of two back legs of the second inverse-U shape piece are correspondingly pivoted with the lower middle parts of the two front legs of the first inverse-U shape piece in order to ensure that no cross bars need to be connected between the two front legs and the two back legs. The structure has the advantages of ensuring the stable support of chair legs in the folding chair structure for the chair board, realizing due application effect, reducing material consumption, saving processing procedures and reducing the production cost of folding chairs, thereby improving the competitiveness of the folding chair structure on the market.
Description
Technical field
The present invention relates to a kind of folding seat, particularly relate to a kind of folding chair structure that need not cross bar.
Background technology
Chair is one of furniture commodity of the most normal use in our daily life, in family room, or in the unit orderly room, plan or all kinds of public place are such as in cinema, library, conference hall, the train/places such as automobile waiting room, people can both see the shadow that uses it, and it and people's life is closely related.Chair of a great variety from structure, has fixedly chair, folding seat, chair lift or the like; From function, be useful on the office chair of work, study, the massage armchair that the therapeutic massage function is provided, the usefulness that is suitable for eating dining chair, be suitable for special-purpose chair of conference chair that meeting uses and cinema, train/automobile waiting room or the like.
Folding seat is a kind of of chair; because it has folding characteristic; can be used as chair when opening uses; the smaller volume of chair when folding; can be easy to carry and store; therefore; be widely used in various occasion; this folding seat of prior art generally includes two forelegs; two back legs; a chair plate; a backboard; about medium position of two forelegs or middle part position on the upper side are articulated with the postmedian position on the relative edge, both sides of chair plate respectively; the chair plate can be overturn around the pivoting point with foreleg; the top of back leg is articulated with the middle and upper part of foreleg and constitutes and can strut into lambdoid structure; wherein; the pivot points of back leg and foreleg is higher than the pivot points of foreleg and chair plate; then be articulated between back leg and the chair plate by a connection piece; the chair plate also can be overturn with respect to back leg; this connector also is provided with location structure usually; make the chair plate when user mode, can not produce rotary movement; backboard then normally is fixed between the top of two forelegs; the chair of this structure; when chair struts and is used; be subjected to the user to be sitting in the effect that the chair plate produces pressure; two forelegs and two back legs very easily shift to both sides; cause the instability of chair leg; therefore; usually need install cross bar additional between two forelegs and between two back legs; during connection; normally two cross bars are welded on respectively between two forelegs and two back legs between, the folding seat of this structure is owing to need to use cross bar; both materials of having used more; increased the manufacturing procedure of welding again, made the cost of manufacture of folding seat higher, influenced the competitiveness of folding seat in market.
