Abstract

The utility model discloses an improved chair, which comprises a seat, wherein a left armrest and a right armrest are symmetrically arranged at two transverse ends of the seat; the left and right armrests comprise armrest surfaces and armrest rods; and one end of each armrest rod is fixedly connected with the lower part of the corresponding armrest surface, while the other end of the armrest rod is fixedly connected with the seat. The improved chair is characterized in that each armrest rod consists of an armrest rod upper section and an armrest rod lower section; one end of the armrest rod upper section is fixedly connected with the lower part of the armrest surface, at least a pair of a first bulge and a second bulge provided with a circumferential included angle of 180 DEG and arranged on the same cross section is arranged at the other end of the armrest rod upper section, and the first bulge and the second bulge can be elastically retractable in the horizontal direction; and one end of the armrest rod lower section is fixedly connected with the seat, a groove for the armrest rod upper section to penetrate through is arranged in the axial direction of the armrest rod lower section at the other end of the armrest rod lower section, and perforations for the first bulge and the second bulge to simultaneously penetrate out of the armrest rod lower section are arranged from top to bottom at an interval on the inner surface of the groove. In the improved chair provided by the utility model, the armrest positions can be adjusted at will.

Description

A kind of improved chair

Technical field

The utility model relates to a kind of chair, relates in particular to a kind of improved chair.

Background technology

Usually, people quite a few time is seated in daily life.Therefore the comfort level of chair is particularly important.At present, common armrests height and position are changeless, so people can't adjust the position of armrests according to the needs of self, are easy to cause hand tired and influence people's normal life under the true situation of abnormal sitting posture if be in for a long time.

The utility model content

Technical problem to be solved in the utility model provides the improved chair of a kind of adjustable armrest position.

For realizing above purpose, the technical scheme that the utility model adopted is: a kind of improved chair, comprise seat, be symmetrically arranged with left and right handrail at the horizontal two ends of seat, this left and right handrail comprises handrail face and bar, one end of bar is fixedlyed connected with the bottom of handrail face, and the other end of bar is fixedlyed connected with described seat, it is characterized in that: described bar is made up of bar epimere and bar hypomere; One end of described bar epimere is fixedlyed connected with the bottom of handrail face, the other end of bar epimere is provided with at least one pair of circumferential angle to be 180 degree and to be positioned at first on same cross section projection and second projection, and this first protruding and second projection is elastic telescopic in the horizontal direction; One end of described bar hypomere is fixedlyed connected with seat, the other end of described bar hypomere is provided with the groove that penetrates for the bar epimere along the axial direction of bar hypomere, and the inner surface of this groove being provided with of interval from top to bottom supplies first projection and second projection to pass the perforation of bar hypomere simultaneously.

The end face of described first projection and second projection is sphere.

One end of described bar hypomere is fixedlyed connected with seat by an installed part.

Compared with prior art, the beneficial effects of the utility model are:

1. because a kind of improved chair of the present utility model, to be provided with at least one pair of circumferential angle be 180 degree and be positioned at the projection of first on the same cross section and second projection at the bar epimere, and this first protruding and second projection is elastic telescopic in the horizontal direction; The axial direction along the bar hypomere of bar hypomere one end is provided with the groove that penetrates for the bar epimere, and the inner surface of this groove being provided with of interval from top to bottom supplies first projection and second projection to pass the perforation of bar hypomere simultaneously.The user can be according to the position of position adjustments bar epimere in groove of perforation during use, and the bar epimere is fixed by first projection and second protruding the cooperation with perforation, thereby realize the position adjustments of armrests, so the utility model adjustable armrest position.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Among the figure: seat 10, left and right handrail 11, handrail face 12, bar 13, bar epimere 13a, bar hypomere 13b, the first protruding 14a, the second protruding 14b, perforation 15, installed part 16.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further details

Referring to shown in Figure 1, a kind of improved chair comprises circular or square seat 10, is symmetrically arranged with left and right handrail 11 at seat 10 horizontal two ends, this left and right handrail 11 comprises handrail face 12 and bar 13, and bar 13 is made up of bar epimere 13a and bar hypomere.

The end of bar epimere 13a is fixedlyed connected with the bottom of handrail face 12, the other end of bar epimere 13a is provided with at least one pair of circumferential angle to be 180 degree and to be positioned at the first protruding 14a and the second protruding 14b on the same cross section, and this first protruding 14a and the second protruding 14b be elastic telescopic in the horizontal direction.

One end 13b of bar hypomere is fixedlyed connected with seat 10 by installed part 16, the other end of bar hypomere 13b is provided with the groove (not shown) that penetrates for bar epimere 13a along the axial direction of bar hypomere 13b, and the inner surface of this groove being provided with of interval from top to bottom supplies the first protruding 14a and the second protruding 14b to pass the perforation 15 of bar hypomere simultaneously.

The end face of the preferred first protruding 14a and the second protruding 14b is sphere.

The user can be according to the position of position adjustments bar epimere 13a in groove of perforation 15 during use, and cooperate with perforation 15 by the first protruding 14a and the second protruding 14b bar epimere 13a is fixed, thereby realize the position adjustments of armrests, so the utility model adjustable armrest position.
