Abstract

The utility model discloses a folding chair. The folding chair comprises a seat support, a leg support, and a supporting block which movably connects the seat support with the leg support; the seat support comprises two front supporting rods and at least one backrest rod; the leg support comprises at least three leg supporting rods; inserting holes in which rods of the seat support and leg rods of the leg support can be inserted are formed in the supporting block; the rods of the seat support and leg support are integrally connected with the supporting block through elastic ropes. According to the folding chair, the supporting block with the inserting holes are in match with the rods of the seat support and the leg support, so that the folding chair is formed; the rods and the supporting block can be connected by the elastic ropes to be folded and stored, and therefore, the folding chair is small in folding size, and easy to carry and store.

Description

A kind of folding seat

Technical field

The utility model is about a kind of folding seat, refers to especially a kind of simple in structurely, and easy folding seat is received in exhibition.

Background technology

Folding seat has Foldable and portable feature, and it is not only applicable to the use in open air and interim place, is also the Emergency use article of household indispensability.Mostly traditional folding seat is that by folding rack, supporting cloth cover forms, and the folding rack of formation is to coordinate a plurality of module compositions by many poles, therefore folds volume larger, cannot preferably embody the feature of light portable, easy-to-collection.

Utility model content

The purpose of this utility model be to provide a kind of simple in structure, to fold volume compacter, the folding seat of more portable and collection.

For achieving the above object, solution of the present utility model is:

A folding seat, wherein: a back-up block that comprises a seat bracket, a chair foot support and flexible connection seat bracket and chair foot support; This seat bracket comprises two front support rods and at least one back pole; This chair foot support comprises at least three foot levers; On this back-up block, establish respectively the jack for each rod member of seat bracket and each foot lever plant of chair foot support, each rod member of seat bracket and chair foot support links together by elastic threads and back-up block.

Described back-up block is a cylinder block, on it, ora terminalis forms oblique surface, under cylinder block, ora terminalis also forms lower oblique surface, is the radial formation outside oblique jack that makes progress at upper oblique surface place, is the radial formation inside oblique jack that makes progress at lower oblique surface place.

The center of described back-up block is an axis hole, and each oblique jack therewith axis hole connects.

The front support rod of described seat bracket and back pole consist of more piece rod member.

Each foot lever of described chair foot support adopts more piece rod member to form.

The described front support rod consisting of more piece rod member, back pole are or/and a foot lever is realized cooperation by connecting rod, and one end of each connecting rod is fixed in a rod member, and the other end and adjacent rod member are pivot bush unit relation.

Adopt after such scheme, the back-up block of the utility model by having a jack is to coordinate each rod member of seat bracket and chair foot support can form a folding seat, and can realize folding of each rod member of folding seat and back-up block by the connection of elastic threads, reach that to fold volume compacter, the function of more portable and collection.

The specific embodiment

As shown in Figures 1 to 4, the utility model has disclosed a kind of folding seat, the back-up block 3 that it comprises a seat bracket 1, a chair foot support 2 and is flexibly connected seat bracket 1 and chair foot support 2, on back-up block 3, establish respectively the jack for seat bracket 1 each rod member and 2 each foot levers plants of chair foot support, seat bracket 1 links together by elastic threads 4 and back-up block 3 with each rod member of chair foot support 2, and is combined with seat support cloth cover 5 on seat bracket 1.

Described seat bracket 1 comprises two front support rods 11 and at least one back pole, and this embodiment arranges two back poles 12;

Described chair foot support 2 comprises at least three foot levers 21;

Coordinate shown in Fig. 3 A, 3B, described back-up block 3 is a cylinder block, on it, ora terminalis forms oblique surface 31, under cylinder block, ora terminalis also forms lower oblique surface 32, at upper oblique surface 31 places, be the radial formation outside oblique jack 311 that makes progress and plant and coordinate for each rod member of seat bracket 1, at lower oblique surface 32 places, be radial formation and make progress that to take 5 holes in inside oblique jack 321(figure be example); The center of this back-up block 3 is an axis hole 33, and each oblique jack 311,321 therewith axis hole 33 connects, and with this, facilitates stretching of elastic threads 4 to put with fixing.

During combination, in the foot lever 21 of two front support rods 11, two back poles 12 and the chair foot support 2 of seat bracket 1, wear respectively elastic threads 4, and in the oblique jack 311,321 that coordinates through each rod member again of each elastic threads 4 to link together with back-up block 3.

When chair uses, only seat bracket 1 and each rod member of chair foot support 2 need be inserted in the oblique jack 321,322 of back-up block 3, otherwise the folding chair period of the day from 11 p.m. to 1 a.m, only seat bracket 1 and each rod member of chair foot support 2 need be extracted from the oblique jack 321,322 of back-up block 3, owing to being limited to the effect of elastic threads 4, making each parts be unlikely to depart from, and can realize the compactest folding, reach minimum folding volume, to facilitate collection and to carry.

Again as shown in Figure 4, the front support rod of seat bracket 1 11 can consist of more piece rod member with back pole 12, and the end of each rod member can form necking down and be beneficial to socket each other, the length after so can further shortening rod member and folding, and order more reasonable fold.During use, the binding force of pine oil to each rod member, shakes each rod member, under the resilient force of epistasis rope 4, chair frame easily can be launched.

The above-mentioned front support rod consisting of more piece rod member 11 is or/and back pole 12 also can be realized and being coordinated by connecting rod 13, and one end of each connecting rod 13 is fixed in a rod member, and the other end and adjacent rod member are pivot bush unit relation.

Certainly, each foot lever 21 of chair foot support 2 also can adopt more piece rod member to form.

For improving the support degree of chair foot rest 2, its foot lever 21 also can arrange four or five, only the oblique jack 321 of back-up block 3 need be set to corresponding with foot lever 21 quantity.

To sum up, the utility model can form a folding seat by having the back-up block 3 of jack 311,321 with cooperation seat bracket 1 and each rod member of chair foot support 2, and can realize folding of each rod member of folding seat and back-up block 3 by the connection of elastic threads 4, reach that to fold volume compacter, the function of more portable and collection.
