Abstract

A folding ladderchair is composed of a back of chair, armrests, back legs of chair, hinges, front legs of chair, a two-stage ladder, a one-stage ladder, lower sections of back legs and through beams. When used as chair, the back legs of chair are extended upward to form the back of chair, and the side frames of the back of chair are extended forward to form the armrests, and the front end of each armrest is coincident with the front legs of chair which are used as the central support of the ladders. Each back leg under the back of chair is divided into two sections, and the very lower section forms the lower section of back leg which is also used as the front support leg of the one-stage ladder, and the front legs of chair are also used the back support legs of the two-stage ladder. Two through beams are arranged between the front support legs of the one-stage ladder and the back support legs of the two-stage ladder, and the one-stage ladder and the two-stage ladder are arranged on the through beams. The inner sides of the upper ends of the front legs are symmetrically provided with hinges which connect the two-stage ladder and a three-stage ladder. The utility model combines ladders and chairs, thereby increasing the functions of use of furniture and providing convenience to the domestic ascending operations which need ladders.

Description

A kind of collapsible ladder chair

Technical field: the utility model relates to furniture, relates in particular to a kind of collapsible ladder chair.

Background technology:, be the furniture commonly used of family as the chair of furniture.Also be the furniture of using always for ladder in the family, but current chairs and ladder, all be the single furniture of effect, and have the single chair of effect at home can be common occurrence, but it then is unlikely preparing that at home the single ladder of effect is arranged, because can increase a lot of troubles to family like that.

The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of collapsible ladder chair is provided, and the function of chair and the function of ladder are united two into one, and folding up promptly becomes chair, and inverted expansion promptly becomes a ladder.The function of using as chair is identical with the chair of prior art, when using as ladder after counter-rotating launches, can satisfy the general needs of ascending a height in the family room.

Summary of the invention: a kind of collapsible ladder chair described in the utility model includes the chair back, handrail, back post, hinge, chair foreleg, secondary ladder, one-level ladder, back post hypomere and through beam and forms.As the chair state time, extend upward by back post and to form the chair back, frame by chair back both sides extends forward, be provided with handrail, when using as chair here is handrail, as two very important strong points, match with the front end and the chair foreleg of handrail when counter-rotating is used as ladder, the chair foreleg is promptly as the intermediate supports of ladder.By the downward chair leg of the chair back, divide to do two sections, nethermost one section promptly as the back post hypomere, said back post hypomere is again as the front leg strut of one-level ladder, the chair foreleg is again as the rear support leg of secondary ladder.Between the rear support leg of the front leg strut of one-level ladder and secondary ladder, be provided with two through beams, the length of said through beam, be equivalent to one-level ladder or secondary ladder two times, that is to say, on the through beam between the rear support leg of the front leg strut of one-level ladder and secondary ladder, be provided with one-level ladder and secondary ladder.Inboard, upper end at the chair foreleg is symmetrically arranged with hinge, by two hinges of symmetry secondary ladder and three grades of ladders is linked together.The height of the chair foreleg and the chair back about equally, like this when using as ladder, three grades of ladders and level Four ladder can keep the normal step state with one-level ladder and secondary ladder.

Use a kind of collapsible ladder chair technology described in the utility model, the feasible collapsible ladder chair that uses as chair at ordinary times, under the state that uses as chair, promptly can be used as a small-sized level Four ladder after counter-rotating launches uses, can satisfy the demand that general family uses ladder, and do not need to acquire specially the ladder of a special use again, increased the function of use of furniture, for needing to provide convenience in the family with some ascend operations of ladder.A kind of collapsible ladder chair described in the utility model can adopt wood materials to make, and also can adopt bamboo and timber material to make, and perhaps also can adopt metallic material to make.Generally speaking, as long as the intensity of material therefor can guarantee the intensity of collapsible ladder chair described in the utility model, the actual material that uses can be unrestricted.
