The armrest comprises a support seat and a holding plate, wherein, the support seat and the holding plate are respectively provided with a circular hole; a pin is threaded through the circular holes to make the support seat and the holding plate connected; an elastic fixing device is arranged between the support seat and the holding plate; an included angle can be formed by the axis of the circular hole on the holding plate and the central axis of the holding plate. As the central line of the circular hole on the holding plate forms the included angle with the central line of the holding plate, the holding plate can be inclined after turning over; accordingly, many chairs which are folded can be conveniently stacked together, and the utility model has the advantages of convenience and practicability.

Description

Turnover armrests

Technical field

The utility model relates to the parts of chair, especially the handrail of chair.

Background technology

The chair that uses in the daily life, mixing handrail can make us sitting more comfortablely, but the chair of Armrest normally can not folded stack be put together, take very much the place, especially in the city of chi soil cun gold, no matter be in office or room, a kind of chair people that not only sat comfortablely but also saved the Armrest in space pursue for a long time, and this just presses for a kind of suitable armrests that is contained on the joint-stool.

Summary of the invention

The purpose of this utility model just provides a kind of suitable turnover armrests that is contained on the folding seat, loads onto the chair of this handrail and can pile up after folding and deposit the saving space together.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: this armrests, and comprise bearing and hold up plate, bearing and hold up plate to be equipped with circular hole, a pin passes circular hole to be made bearing and holds up plate to be connected; Bearing and hold up elastic fixing device is housed between the plate.The described axis of holding up circular hole on the plate with hold up the plate central axis to have angle.

Armrests of the present utility model holds up plate to go to bearing top in use, because the bounce effect of shell fragment makes and holds up plate and bearing to fix in the elastic fixing device.When chair does not use, be rotating shaft with the pin, firmly holding up the plate upset, hold up plate to go to the side of bearing, still, make and hold up plate and bearing to be fixed owing to the effect of shell fragment bounce.Owing to hold up the center line of circular hole on the plate to become angle with holding up the plate center line, so tilt after holding up the plate upset, the chair after being convenient to several folded is piled up together.

Fig. 8 is that two folding seat that adopt the utility model to make handrail are piled up schematic diagram together.

The specific embodiment

The structure of bearing 1 such as Fig. 1, Fig. 2, shown in Figure 3, there are two boss 11 bearing 1 top, and there are two concentric circular holes 111 at boss 11 centers, and supply and marketing 2 is passed; The top of boss 11 is a plane 112, and lateral surface also is a plane 113.The striped place, below of bearing 1 is used for assigning on the chair frame.

As Fig. 4, shown in Figure 5, hold up plate 3 belows that two boss 31 are also arranged, there are two concentric circular holes 311 at boss 31 centers, and supply and marketing 2 is passed.One groove 32 is arranged between two boss 31, and ammunition feed sheet 4 is placed wherein.The center line of two circular holes 311 and the center line of holding up plate 3 α that has angle.

During assembling, earlier shell fragment 4 is positioned in the groove 32, then pin 2 is passed bearing circular hole 111 and holds up plate circular hole 311, fixing getting final product.Shell fragment 4 can be selected shapes such as " U " type, " C " type or " O " type for use.Certainly, groove 32 also can be located on the bearing 1, and the shell fragment 4 that is placed in one is held up plate 3 to be fixed, and reason is the same, should be to fall within the protection domain of the present utility model equally.

As shown in Figure 6, when handrail used, holding up plate 3 to go to the top of bearing 1, the plane 112 at bearing top contacted with the below of flexure strip 4.Because the elastic force of shell fragment 4 makes and holds up plate 3 and bearing 1 fixing firmly, above staff rode over, it was fixed holding up plate.When not in use, pin and hold up plate 3, shell fragment 4 is compressed distortion, gets final product holding up plate 3 to turn to outward on the side plane 113 of bearing 1, as shown in Figure 7.Also be because the effect of the bounce of shell fragment 4 makes and holds up plate 3 steadily to be fixed on the bearing 1, can not rock.Owing to hold up the center line of the circular hole on the plate and hold up the plate center line to have angle, therefore hold up plate to tilt after the upset.So when the folding seat that this handrail has been installed more than two and two was piled up together, as shown in Figure 8, each handrail oblique arrangement does not hinder before and after not understanding mutually, can save the space widely, and was very practical.
