Description

Chair used folding bed

The utility model relates to a kind of chair used folding bed.

Foldable bed group kind is very various, probably only be left " camp bed " at the early stage goods that can see on the market at present, its be simple with the metal pipe frame collocation canvas that can amount to or nylon cloth to constitute the bed of a deployable or folding, certainly also there is manufacturer to be made into folding bed than firm, it is the pivot joint design of adopting the M type, as Taiwan patent announcement number No. 335651 " the improvement structure of folding bed ", deployable one-tenth bed group when using, when not using, then directly folded, but this series products only can provide simple bed group function, and can't use as seat, so its practical value is not high.

Based on the demand in market and the popularization of relevant manufacturer, divan surely belongs to the another kind of pattern of folding bed, it can be used as the bed group upon deployment, then can be used as sofa after folding uses, this is to belong to novel design, but this type of the design mainly be for household use be main, so after folding, all be the sofa moulding of unidirectional seat pattern, leave promptly very rare its practical space of family.

The current folding bed that in the ward of various big hospital, can see another pattern mostly, it mainly is the usefulness that dosses night for the family members that accompany disease, but in the daytime then folding become a seat, this type of design is to adopt three-bend bedstead, the bed group that is the plane during expansion, and be to make wherein being two bedsteads that inverted V-shape articulates and erectting to form the chair back when folding, and another bedstead keeps level, to constitute a unidirectional seat, this kind folding bed monoenergetic is enough in the use of bed group, also can be used as simultaneously seat uses, its practical value is higher, but it is subject to the restriction on its structural design, its folding becomes promptly can't go behind the seat volume of folding Cheng Gengxiao again, so cause the puzzlement in collection or the transportation, it is subjected to the structural limitations of foot rest again, also cumbersome when mobile, obviously it still has in addition improved necessity, it only can be as unidirectional seat after folding in addition, if in the space and needs that utilize and when wishing can bidirectional seat be arranged, it promptly can't meet required, so that the structure of existing this type of folding bed there is no is perfect.

Main purpose of the present utility model is to provide a kind of chair used folding bed of diverse practicality, it can be launched into the bed of plane pattern, also frame in two can be erect and form bidirectional seat, or only one-sided end frame is kept flat and become general unidirectional seat, and help collection or transportation.

The purpose of this utility model is to realize like this, a kind of chair used folding bed, be characterized in: this folding bed is that a kind of bedstead is four-folding and adopts the W type to articulate the folding bed of configuration, it is to be articulated by frame among two ends frame and two to form, be provided with the end cabinet base in end frame end below, being articulated with middle seat between end frame and middle frame combines, and is articulated by brace between frame in two, and the while is extended cabinet base in below the brace between frame in two.

Described chair used folding bed is characterized in: middle frame side is provided with cramp, and end frame side is provided with the button of buckleing that matches.

Described chair used folding bed is characterized in: the seat side is provided with cramp in one, and the seat side is provided with the button button that matches in another.

Described chair used folding bed is characterized in: middle seat below is provided with roller.

Described chair used folding bed is characterized in: the body of rod inboard of described end frame end is pivoted with the end cabinet base, and is articulated with connecting rod on the end cabinet base, and the end in addition of this connecting rod then is articulated on the pivoted pole of middle seat.

Described chair used folding bed is characterized in: end seat and middle frame are the both sides of seat in being hubbed on respectively, and middle seat upper limb centre is provided with the catch that an end that can be blocked in end frame or middle frame when end frame or middle frame launch horizontal is located.

Described chair used folding bed is characterized in: an inboard position by central authorities is respectively equipped with a cross bar in two, and is connected with a pull bar between this two cross bar and middle cabinet base respectively, and the two ends of this two pull bar are pivot joint between cabinet base respectively and during the cross bar of seat reaches in one.

Described chair used folding bed is characterized in: seat is provided with a jacking block by the edge of seat in another in one.

The utility model compared with the prior art advantage and good effect is very obvious, it is that a kind of bedstead is four-folding and adopts the W type to articulate the folding bed of configuration, that is it is to be articulated by frame among two ends frame and two to form, the bed of its deployable one-tenth plane pattern, also frame in two can be erect and form bidirectional seat, or only one-sided end frame is kept flat and become general unidirectional seat, and can provide diverse practicality.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
