Abstract
The utility model relates to a supporting frame for chair arm rests, which comprises an arc-shaped supporting frame body of which the cross section is elliptic, wherein the upper end of the arc-shaped supporting frame body is a flat end plane with slight gradient, and the lower end is a vertical end plane; the upper end of the arc-shaped supporting frame body is provided with the arm rests for connecting with screw holes, and the lower end is provided with a chair frame for connecting the screw holes; the arc-shaped supporting frame body is provided with a long slot of which the direction is identical with the arc-shaped direction of the arc-shaped supporting frame body; the long slot is provided with a long sleeve which is embedded in the long sleeve, and both edges of the long sleeve are jointed. When the utility model adjusts the incline of a backrest, connecting bolts slide along the long slot and are tightly locked; when the backrest forms a slightly wrapping state on a seat cushion, the backrest can tilt a certain angle, and an arc-shaped slideway can make free and smooth motion; the utility model accords with the design of humanization.
Description
Technical field:
The utility model relates to a kind of parts of seat, particularly the armrest support.
Background technology:
The seat of prior art has seat base, support, cushion, the handrail of backrest, the two side faces that handrail is installed on cushion and backrest is connected by the connector (for example gas bar) of cushion bottom, perhaps directly use handrail and armrest support and connect cushion and backrest, its weak point is: as the words that connect with the gas bar, the connecting elements complexity, production cost is higher, connect as direct application handrail and armrest support, the inclination of cushion and backrest is the stiff perk of straight line to people when lying facing upward, it is dumb to move, and stick up very highly, and cause both feet to break away from ground and feel very ill, can not play the purpose that the short time has a rest.
The utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, and production cost is low, and passes through cambered way when backrest inclination, and cushion keeps little state that sticks up, and the armrest support of comfortable rest of short time is provided for people.
The technical scheme of the utility model armrest support, comprise the arc support body, the upper end is the planar end surface of gradient slightly, the lower end is a perpendicular end surface, the upper end is provided with handrail and connects screw, the lower end is provided with the chair frame and connects screw, and described arc support body has the elongated slot identical with the arcuate directions of arc support body.Described elongated slot is provided with the embedding of long cover phase.Described long cover both sides are involutory.The cross section of described arc support body is oval.
The beneficial effect of the utility model armrest support is: the upper end of arc support body is connected with handrail, and the lower end is connected with the chair frame, penetrates the connecting bolt that is connected with cushion in the elongated slot.Connecting bolt slides along elongated slot and locks then when adjusting backrest inclination.When being formed on cushion and slightly sticking up state, backrest tiltable certain angle, and the cambered way motion freely, smooth and easy, meet human oriented design, can change slightly to reach at existing armrest support and face upward the purpose of lying, reduce production cost, enhance one's market competitiveness.
Description of drawings:
Fig. 1 is the front view of the utility model armrest frame;
Fig. 2 is the profile of Fig. 1 along the A-A tangent plane;
Fig. 3 is that Fig. 1 C is to view;
Fig. 4 is that Figure 1B is to view.
The specific embodiment:
Fig. 1, Fig. 2, the described armrest support of Fig. 3, Fig. 4, comprise arc support body 1, the upper end is the planar end surface of gradient slightly, the lower end is a perpendicular end surface, the upper end is provided with handrail and connects screw 4, the lower end is provided with the chair frame and connects screw 5, and its arc support body has the elongated slot 3 identical with the arcuate directions of arc support body 1.Its elongated slot 3 is provided with the 2 phase embeddings of long cover.Its long cover 2 both sides are involutory.The cross section of its arc support body 1 is oval.
During installation, the front end of the upper end end face fixed armrest of arc support body 1, the rear end of handrail and backrest flexibly connect, and the chair frame is fixed in the lower surface of arc support body 1, penetrates in the elongated slot 3 and the cushion connecting bolt.Unclamp connecting bolt during use, the inclination backrest becomes proper angle, screws connecting bolt then and gets final product.
