Description

Bench seat with split back

The utility model relates to a kind of seat, particularly a kind of bench seat with split back.

The form of present chair is a lot, the fixed seat big and that can not amount to that takes up space is arranged, support and the folding folding seat of seat cushion part are arranged, but its folding or shoveing get out, there is band can hang the seat of writing table that props up, shows institute in addition, row's chair that use in big meeting-place for reception room and classroom use, the seat cushion of row's chair partly is hubbed on the supporting leg, so it can lift and puts.

Therefore though the version difference of above seat, outside function was distinguished to some extent, its effect all was identical, and single, i.e. therefore conversion and change its function of use mutually also just can not enlarge the scope of application and reduce acquisition expenses.

Another major defect is because each critical piece of existing seat can not at will need the conversion combination temporarily or by use, so, before dispatching from the factory, assembled and finished, therefore, depositing before dispatch from the factory, the transportation when dispatching from the factory, the stock after the applying unit or put all exist take up space big, the landed cost height, the problem that breakage rate is high.

A deficiency is exactly that serviceability is also more single because it can not conversion chair kind again.

The purpose of this utility model just is to restrain the above-mentioned shortcoming and defect of existing prior art, and a kind of each critical piece flexible combination and can change chair kind and function of use relatively is provided, detachable and be convenient to the reduced space of Rapid Combination in handling process, save the bench seat with split back of trucking expenses.

The purpose of this utility model is to realize by following technical scheme:

On the hypomere of the ancon link of two symmetries, offer with foot rest mutually sleeve the lug hole and plug in the dovetail groove of embedding mutually with handrail, backrest is fixed on the upper lateral of ancon link by screw, seat cushion is inserted by the raised line of its both sides and is embedded in the hypomere slot of two links, the cushion rack that is inserted in from the inboard the link lug hole is arranged in the seat cushion bottom, constitute a chair with foot rest by combinations thereof.Then can become the table-arm chair that the student writes down use as clipboard on pegging graft on handrail top, change foot rest single legs and feet frame of pulley into, can become and be fit to the office chair that office uses, place horizontal foot rest in the chair cushion bottom, then the row's of can be changed into chair.

Therefore: remarkable result of the present utility model is:

The 1st: because its each parts can be at the applying unit ease of assembly, therefore, its parts can be deposited separately before dispatching from the factory and needn't assemble and deposit, not only reduced and taken up space, and, help the reduction of cost of transportation, and can reduce the breakage rate in the integral body carrying.

The the 2nd: because it can carry out conversion as required and be used in combination,, and reach the many usefulness of a chair, both improved the scope of application of seat, can reduce acquisition expenses relatively again promptly by the plus-minus parts.

The 3rd: it is strong to have the parts symmetry, assembles characteristics fast and easily.
