Description

A kind of support for folding chair

Technical field

The utility model is about a kind of folding seat, refers to a kind of support for folding chair especially.

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 supporting cloth cover by folding rack is formed, the folding rack formed is that many poles coordinate multiple module composition, utilize folding rack to launch and coordinate the restriction of cloth cover and form the chair of stationary state, namely it possesses the two states launched with folding, but the state complying with seat when user uses is fixed, and cannot have multi-functional use as normal chair, and it folds volume comparatively greatly, preferably cannot embody the feature of light portable, easy-to-collection.

Therefore, the design people has just invented one, and to fold volume compacter, simple, light, the more portable folding seat with collection of structure.Coordinate shown in Fig. 1, this folding seat coordinates each rod member 2 ' of seat bracket and chair foot support can form a folding seat primarily of the Connection Block 1 ' with jack, and each rod member 2 ' and the connection of Connection Block 1 ' can be realized each rod member 2 ' of folding seat and folding of Connection Block 1 ' and not loose function by elastic threads; This Connection Block 1 ' is by the upper bracket 11 ' of mutual pivot joint and undersetting 12 ', realizes with this relation forming mutual flexible rotating between chair foot support that seat bracket that upper bracket 11 ' coordinates coordinates relative to undersetting 12 '.

But at least there is following shortcoming in use and wait to improve in above-mentioned folding seat:

First, connected by Connection Block between chair foot support and seat bracket, during expansion, chair foot support and seat bracket are by Connection Block radiated entends outward, namely little state wide up and down in the middle of being formed, therefore, the weight on seat support all has Connection Block to bear, user need keep center of gravity placed in the middle when being seated at seat support, if lean to too backward, turn over after easily making folding seat, during left and right deviation, also easily cause this folding seat to turn on one's side, therefore the support strength of folding seat has to be strengthened.

Secondly, chair foot support and be connected by elastic drag rope between seat bracket with Connection Block, when folding, needs each rod member to extract from the jack of Connection Block one by one, at the jack each rod member one_to_one corresponding being inserted Connection Block during use, folding like this, to launch efficiency quite low.

Utility model content

It is large that the purpose of this utility model is to provide a kind of support strength, convenient folding, efficiently support for folding chair.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of support for folding chair, comprise the seat bracket with two front bars and two back poles and the chair foot support having four foot levers, the center pillar also comprising chair bar Connection Block, foot lever Connection Block and be located between chair bar Connection Block and foot lever Connection Block, foot lever Connection Block is located at the top of chair bar Connection Block, seat bracket is articulated on chair bar Connection Block, chair foot support is articulated on foot lever Connection Block, and each rod member of the corresponding chair foot support of each rod member of seat bracket is be crisscross arranged up and down, and in the mutual pivot joint of infall.

Described chair bar Connection Block and foot lever Connection Block are all in cross structure, and corresponding up and down, and form four driving rods and four pivot connected slots respectively.

What each rod member of described seat bracket was evenly distributed is articulated on the driving rod of each pivot connected slot the same side of chair bar Connection Block, and on the equally distributed driving rod being articulated in each pivot connected slot opposite side of each foot lever Connection Block of each rod member of chair foot support, make each rod member of the corresponding chair foot support of each rod member of seat bracket in interlocking up and down.

Two front support rod being of described seat bracket are articulated in and are positioned on the same pivot connected slot inwall of chair bar Connection Block, and two back poles of seat bracket are articulated on the pivot connected slot outer wall relative with two front bar pivot connected slots; And chair foot support and two foot levers of two front support rod the same sides are articulated on foot lever Connection Block and the corresponding pivot connected slot outer wall of front bar pivot connected slot, other two foot levers are articulated on the inwall of another pivot connected slot relative with this pivot connected slot, and each rod member of the corresponding chair foot support of each rod member of seat bracket is in being crisscross arranged up and down.

The below of described chair bar Connection Block arrange one in the middle part of foot lever.

Described center pillar is be arranged at the outer tube below foot lever Connection Block, the top of described chair bar Connection Block arrange one can coordinate with center pillar in pipe.

The infall of each rod member of the corresponding chair foot support of each rod member of described seat bracket arranges backing plate respectively at relative side.

After adopting such scheme, a kind of support for folding chair of the utility model is by foot lever Connection Block setting up and down and chair bar Connection Block, make be articulated in each foot lever of foot lever Connection Block and be articulated in each chair bar of chair bar Connection Block in being crisscross arranged up and down, so greatly increase the integrated support intensity of folding seat, turn over after effectively can avoiding making due to deviation of gravity center folding seat produce or turn on one's side, increasing the security used.And each rod member is mutual pivot joint arranges, make this support for folding chair launch or folding time, all only need pull out or inwardly press any two rod members, other rod members can follow action, so easily realize launching and folding, convenient and quick.
