Abstract

The utility model provides a folding chair with scissors type feet, comprising every bisymmetry front and rear chair feet(1, 2) and a back frame rod(12). The utility model is characterized in that two groups of symmetrical chair feet with scissors type feet(6) are formed, after the front and rear chair feet(1 2) are hinged through regulation(3) and selection of angle; at least two regulation holes(8) are respectively arranged at the crossed point of the front and rear chair feet. The utility model has the advantages of low cost, good stability, the regulation of the height of the chair frame and the inclination of the chair back frame, gathering and folding ability, and convenient use.

Description

Scissor foot type folding chair

Technical field:

The utility model relates to a kind of folding chair, particularly be a kind of scissor foot type folding chair.

Background technology:

Existing commercially available folding chair, because of the reason of structural approach, poor stability, constructional variant is big, so it highly all is changeless, can not satisfy the demand of different height users to chair height.

The utility model content:

The purpose of this utility model is in order to provide a kind of simple in structure, and cost is low, good stability, and chair height and chair back rack gradient are adjustable, and also can make things convenient for the scissor foot type folding chair of folding.

The utility model scissor foot type folding chair comprises the forward and backward foot (1,2) and the back-frame rod (12) of each two symmetry, it is characterized in that forward and backward chair foot (1,2) and back-frame rod (12) pass through regulating part (3) after the apolegamy angle is hinged, the scissor typed chair foot (6) that is two groups of symmetries, and have respectively at infall and to be no less than two adjustment holes (8).

Above-mentioned chair front foot (1) upper end is disjunctor with chair back hack lever (12) and is hinged.

Above-mentioned chair metapedes (2) upper end is hinged by tender with chair frame support member 7 lower ends, and its upper end is hinged by tender with chair plate connector.

Above-mentioned regulating part (3) is fastening with nut by each corresponding adjustment hole (8) of forward and backward chair foot (1,2) middle part, is the scissor typed chair foot (6) of two groups of symmetries.

Rear chair foot (14) upper end of above-mentioned another through prolonging, it is hinged to pass through articulated elements with the same mode of chair frame support member (7) and arrow shaped chute support member (13) and chair plate connector (9).

Above-mentioned scissor typed chair foot (6) can be regulated between 50 °-65 ° at the infall pin joint angle α 1 at middle part.

Above-mentioned scissor typed chair foot (6) is at 1=58 ° of optimum efficiency of middle part infall pin joint angle α, and is comfortable.

Referring to Fig. 1-Fig. 2, the utility model by forward and backward chair foot (1,2) with regulating part (3) after the apolegamy angle is hinged, be the scissor typed chair foot (6) of two groups of symmetries, and good stability, the user is sitting on the utility model scissor foot type folding chair, so comfortable sense is arranged, has firm real again.

The utility model is simple in structure, but chair frame height and back of the body frame gradient are adjustable, can strengthen health, and the sitting posture structure is comfortable, and cost is low, but convenient folding again reduces and takes up an area of the space.

The specific embodiment:

Embodiment 1:

Referring to Fig. 1--Fig. 2, chair foot 1 before two symmetries, rear chair foot 2, regulating part 3 passes the corresponding adjustment hole that a plurality of adjustment holes 8 of forward and backward chair foot 1,2 on infall are complementary, and is fastening with nut.After forward and backward chair foot 1,2 and connecting rod 4,5 are hinged, the scissor typed chair foot 6 that is two groups of symmetries, chair frame support member 7 lower ends and rear chair foot 2 upper ends are hinged by tender, the chair plate connector 9 of chair frame support member 7 upper ends and two symmetries is hinged by tender, chair plate 10 is fastening by tender after being hinged with chair plate connector 9, and the corresponding position of the back-frame rod 12 of chair back plate 11 and two symmetries is hinged by tender.

Embodiment 2:

Referring to Fig. 1-Tu, 3 present embodiments 2 basic with embodiment 1 with, do not exist together be through prolonging rear chair foot 14 upper ends directly and arrow shaped chute support member (13) and chair plate connector (9) to pass through tender simultaneously hinged.

Embodiment 3:

Referring to Fig. 1--Fig. 4, embodiment 3 basic with implement 1,2 with, not existing together is that forward and backward chair foot 1,2 middle parts have only an adjustment hole by regulating part 3, the hinged scissor typed chair foot 6 that is can be regulated between 55 °-59 ° at middle part infall pin joint angle α 1.

Claims

1, scissor foot type folding chair, the preceding rear chair foot (1,2) and the chair back hack lever (12) that comprise each two symmetry, it is characterized in that forward and backward chair foot (1,2) by regulating part (3) through match angle hinged be the scissor typed chair foot (6) of two groups of symmetries and have respectively at its infall be no less than two adjustment holes (8).

2, scissor foot type folding chair according to claim 1 is characterized in that linearly disjunctor hinge of preceding chair foot (1) upper end and chair back rack (12).

3, scissor foot type folding chair according to claim 1 is characterized in that rear chair foot (2) upper end and chair frame support member 7 lower ends are hinged by tender, and its upper end is hinged by tender again with chair plate connector (9).

4, scissor foot type folding chair according to claim 1 is characterized in that regulating part (3) passes each corresponding adjustment hole (8) of forward and backward chair foot (1,2) middle part with the fastening scissor typed chair foot (6) that is two groups of symmetries of nut.
