Abstract

The utility model relates to a multi-purpose folding chair belonging to the improvement on a common folding chair. The aim of the utility model is to overcome the single function of the common folding chair for obtaining the purpose of one chair with multiple functions. The multi-purpose folding chair is characterized in that a pin pole is clamped with different curved concaves of a long slot to complete the deformation from a chair to a table or a simple bed. The utility model has multiple functions, is convenient in carrying, and is particularly suitable for outdoor operation, such as geological exploration, art design, etc.

Description

Multiple purpose folding chair

Collapsible multi-functional chair belongs to daily life tools.

Current have many kinds of folding seat, as Winter-summer dual purpose folding seat, sofa-type folding seat etc., all only has the function of making chair.

The open air of aspects such as geological prospecting, art designing's art, engineering construction (or open-air) operation, the needs for satisfying drawing, measuring, write down, have a rest need carry articles for use such as table, chair, bed, and are very inconvenient.The purpose of this utility model is to overcome the unicity of existing common folding seat function, realizes that a chair uses more.Both satisfied the seat needs of fixed-sites such as family, meeting room, club, more satisfied outdoor study needs easy to carry.

The primary structure of collapsible multi-functional chair is: 2 of seat board 1 and backup plates are by hinge-coupled; Channel 3 has elongated slot, and a side of groove is arc concave, and channel is fixed on the back side of backup plate; Preceding support middle-end is fixed with Xiao Zhu 5 by hinge-coupled for 4 of seat board and preceding supports, and tail end has elongated slot; Curved rod 6 upper ends are fixed with Xiao Zhu 7, insert in the elongated slot of channel, and the lower end is fixed with Xiao Zhu 8, support in the elongated slot of tail end before inserting; Front leg strut 9 and curved rod middle-end are by hinge-coupled, and front leg strut has elongated slot, and a side of groove is arc concave, in the Xiao Zhu insertion groove of preceding support middle-end.After the shape of chair is determined, when the Xiao Zhu of the Xiao Zhu of support and curved rod blocks with certain arc concave of front leg strut elongated slot and channel elongated slot one side respectively before making, get final product solid shape.As shown in Figure 1.Form in the process of simplified desk by chair at collapsible multi-functional chair, preceding support, front leg strut and curved rod maintain static, seat board rotates counterclockwise, driving backup plate is fulcrum with the Xiao Zhu on the curved rod, not only seesaw, but also rotatablely move, when thinking that formed table shape meets the demands, certain arc concave of channel elongated slot one side and the Xiao Zhu of curved rod upper end are blocked, get final product solid shape.Shown in position A among Fig. 2.In like manner, formed by chair in the process of desk, seat board can form the multiple different gradient with backup plate, to adapt to the needs of some industry (as drawing).When thinking that the shape that forms meets the demands, certain arc concave of channel elongated slot one side and the Xiao Zhu of curved rod upper end are blocked and solid shape.Shown in position B among Fig. 2.Form by chair in the process of simple and easy bed (half bed) at collapsible multi-functional chair, compound motion is done in preceding support, except that doing the rectilinear motion by the Xiao Zhu control of curved rod, also the Xiao Zhu with curved rod is a fulcrum, do and be rotated counterclockwise motion, make seat board move downward, simultaneously, the Xiao Zhu of preceding support makes that also front leg strut closes up to curved rod.Wherein, when above-mentioned motion acquires a certain degree, seat board can not rotate again, and preceding support then drives seat board and moves to the backup plate plate, reaches the shape of desired bed.At this moment, the Xiao Zhu of the Xiao Zhu of preceding support and curved rod upper end blocks with certain arc concave of a side of the elongated slot of the elongated slot of front leg strut and channel respectively, makes the fixed in shape of bed (half bed).As shown in Figure 3.

That collapsible multi-functional chair can be made into is single seat, double seat etc.

Two collapsible multi-functional chairs are used: as two equal shapes is chair, promptly can be used for talks; As a shape is chair, and another shape is a simplified desk, promptly can be used for writing; As two equal shapes of chair is that seat board and backup plate are tending towards on the straight line, can form a simple and easy bed.

Link joint is adopted in many places of the present invention, thus flexibly folding, can make the tables and chairs bed as required and use, bring great convenience for the operator that goes out.

Claims

1, but a kind of deformation is the collapsible multi-functional chair of desk or bed, is made up of seat board 1, backup plate 2, preceding support 4, curved rod 6 and front leg strut 9, it is characterized in that:

Fix a channel 3 on a, the backup plate 2, and the tail end of channel 3, front leg strut 9 and preceding support 4 has elongated slot,

B, seat board 1 and preceding support 4, front leg strut 9 and curved rod 6 middle-ends are by hinge-coupled.

2,, it is characterized in that said elongated slot one side is certain arc concave according to the said collapsible multi-functional chair of claim 1.
