Description

The collapsible ladder chair

The utility model relates to a kind of collapsible chair that is transformed into ladder.

Foldable chair has a variety ofly in the prior art, but the collapsible chair that is transformed into ladder is rarely found, and general folding seat all is to design for folding and unfolding is convenient, is not multiduty functional mapping.The CN90224538 patent disclosure a kind of Collapsible ladder chair, it is made up of front and back support and upper, middle and lower three ply board, the item end of front and back support and the rear portion employing activity of top plate connect, and la m is fixed on the after-poppet with axle, and last la m can overturn around coupling spindle separately, lower plywood can constitute around the axle upset that is fixed on the fore-stock, it is with can using as chair and ladder conversion, but it is structural and bad, and volume is big, poor practicability can not really be used as chair is convenient.

The purpose of this utility model provides the strong multifunction chair of a kind of applicability, and a kind of collapsible chair that is transformed into ladder promptly is provided.

Technical solution of the present utility model is, by the chair frame, on the basis of the basic structure of the chair that seat board constitutes, first half in the seat board bottom of chair is provided with a up-small and down-big triangular supports, the latter half of chair frame hinge-coupled of the inner top side portion of this triangular supports and seat board bottom, the common support body that constitutes under the seat board, form seat, the rear portion of seat board and chair frame hinge hinge-coupled, seat board can upwards be dug, after the chair frame at seat board rear portion is turned over the turnback angle around the hinge of itself and three supports, the upper surface of the upper surface of chair frame and A-frame is overlapping under the seat board, chair is placed on the A-frame, land the upper end of the seat postero dorsal arm of chair frame, and the lower end of chair frame forms ladder up.
