Detailed description of the invention

Be below that specific embodiment of the utility model is also further described the technical solution of the utility model by reference to the accompanying drawings, but the utility model is not limited to these embodiment.

The utility model provides a kind of folding seat, as shown in Figures 1 to 9, at least comprises chair foreleg 1, back post 8, seat plate 4 and hinged chair foreleg 1 and back post 8, makes the two relatively turnable articulated structure.

Certainly, in order to have more comfortableness, the folding seat of the present embodiment also comprise be fixedly installed in chair foreleg 1 top backboard 7, be fixedly installed in the handrail 6 at chair foreleg 1 middle part and with the opposing backrest protective board 5 of handrail 6, and be fixedly installed in the pedal 3 of chair foreleg 1 bottom.

In addition, said structure can be made with plank, also can adopt other materials.As shown in Figure 1 and Figure 2, chair foreleg 1 is two rods, and two rod bottoms connect by foreleg stationary pipes 2.Back post 8 is " Contraband " font of a bend pipe composition.

Inventive point of the present utility model is, a kind of new articulated structure is provided, make hinged more firm, longer service life, its concrete structure is as shown in Fig. 3, Fig. 4, Fig. 5.

Articulated structure at least comprises thimble plug 11, shell fragment 12, reinforcing chip 13 and button panel 14, thimble plug 11 can be the cannula tip being directly shaped in the back post 8 downward perforates in top, also can be the cover tube components being set on back post 8 tops, if adopt the latter can avoid casing failure and need to change whole back post.

Thimble plug 11 can be directly and chair foreleg 1 hinged by the bearing pin of level, for fear of chair foreleg 1, because of long-term stressed damage, preferably, articulated structure also comprises back leg Connection Block 9, back leg Connection Block 9 is fixedly mounted on chair foreleg 1 by screw.Bearing pin, through back leg Connection Block 9 and thimble plug 11, make thimble plug 11 and back post 8 to rotate and to fold with respect to chair foreleg 1 around bearing pin, and force and deformation can be delivered on back leg Connection Block 9 instead of chair foreleg 1, can avoid the replacing of overall chair.Preferably, as shown in Figure 2 and Figure 3, back leg Connection Block 9 is covered with trim 10, attractive in appearance to strengthen.

Back leg Connection Block 9 is positioned at a side of thimble plug 11, and the opposite side of thimble plug 11 is provided with reinforcing chip 13 and button panel 14, and shell fragment 12 is contained in thimble plug 11.Wherein, shell fragment 12 comprises elastic portion and projection, and thimble plug 11 has hole on a side sidewall of reinforcing chip 13, and position corresponding on reinforcing chip 13 is also provided with through hole.As shown in Figure 4, the elastic portion of shell fragment 12 is positioned at thimble plug 11, and under the effect of elastic force, promotes the hole of projection from thimble plug 11 sidewalls and stretch out, and extend in the through hole of reinforcing chip 13.Now, back post 9 is angled with respect to chair foreleg 1, in opened condition, and spacing by this projection, cannot rotate.Whole folding seat as shown in Figure 8.Preferably, the elastic portion of shell fragment 12 is V-structure, the hole that it snaps in thimble plug 11 and promotes projection and stretch out thimble plug 11 sidewalls.

Reinforcing chip 13 is fixed by screws on button panel 14, and button panel 14 covers on reinforcing chip 13, and is fixed on back leg Connection Block 9 by screw, thereby is relatively fixed on chair foreleg 1.On button panel 14, be provided with a button corresponding to the position of through hole on reinforcing chip 13, this button can extend in aforementioned through-hole after pressed by external force, thereby the projection that promotes shell fragment 12 leaves through hole and is retracted in thimble plug 11, as shown in Figure 5, now thimble plug 11 can rotate and fold around bearing pin together with back post 8.

Further, in order to show that back post 8 relatively rotates superimposed angle, on the sidewall of back leg Connection Block 9, be provided with angle of rotation indicator collet at thimble plug 11.Accordingly, on back leg Connection Block 9, offer arc chute, this arc chute is taking aforementioned bearing pin central point as the center of circle, and the distance taking angle of rotation indicator collet to this bearing pin is radius, and angle of rotation indicator collet is positioned at arc chute., by checking angle of rotation indicator collet, can know whether this folding seat folds, as shown in Figure 6.When angle of rotation indicator collet as shown in Figure 7, now the chair foreleg 1 of folding seat and back post 8 merge, and can stand, folding seat as shown in Figure 9.

Further, for fear of the excessive and wearing and tearing back leg Connection Block 9 of back post 8 angles of rotation, on back leg Connection Block 9, be also provided with to described back post 8 projections, the limited block that stops it to be rotated further.

Adopt folding seat of the present utility model, snap in the through hole of reinforcing chip 13 locate by the projection of shell fragment 12, folding seat is firm open mode; In the time that needs fold this chair, press the button on button panel 14, projection is returned in thimble plug 11, folding seat foldable one-tenth can standing state.This state changes to be realized by elastic force, instead of existing frictional force, can not wear and tear to chair foreleg and the back post of hinged place, thus the life-span of having improved folding seat, and state is more firm.

Above-mentioned these situations, all belong to the claimed scope of the utility model, are not limited in above-described embodiment.The utility model person of ordinary skill in the field can do various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
