Abstract

A supporting structure for a chair, the supporting structure is a seat, a back support or a headrest. A nylon mesh is fixed on the annular upper surface of an inwardly projecting flange of the frame, and then the plastic-injection-molded engaging layer is integrally formed on the exterior surface of the frame, enabling the mesh to be firmly fixed on the frame. The elasticity of the mesh provides a comfortable and adequate support for the user's buttocks, back and head, providing comfortable seating and preventing muscle soreness. Further, the heat caused by the user's body can be vented off via the apertures of the mesh, so that the user will feel cool when sitting on or leaning against the supporting structure.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a supporting structure for a chair, and more particularly to a supporting structure for a chair that comprises a frame and a nylon mesh fixed on the frame. The elasticity of the mesh provides a comfortable and adequate support for the user's buttocks, back and head, providing comfortable seating and preventing muscle soreness. And the user will feel cool when sitting on or leaning against the supporting structure since the mesh is breathable.
  • 2. Description of the Prior Art
  • A conventional chair 100 (as shown in FIG. 1) comprises a seat 102 disposed on a leg 101, a back support 103 fixed at the rear side of the seat 102, and a headrest on the top of the back support 103. The seat 102, the back support 103 and the headrest 104 serve to support user's buttocks, back and head. However, the seat 102, the back support 103 and the headrest 104 are made of foam material and are too soft to provide adequate support, which is likely to cause muscle soreness. Further, the foam material-made seat 102, the back support 103 and the headrest 104 are not breathable, so the user will uncomfortable.
  • The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
    • SUMMARY OF THE INVENTION
  • The primary objective of the present invention is to provide a supporting structure for a chair, the support structure is a seat, a back support or a headrest. A nylon mesh is fixed on the annular flange of the frame, and then the plastic-injection-molded annular engaging portion is integrally formed on the outer periphery of the frame, enabling the mesh to be firmly fixed on the frame. The elasticity of the mesh provides a comfortable and adequate support for the user's buttocks, back and head, providing comfortable seating and preventing muscle soreness. Further, the heat caused by the user's body can be vented off via the apertures of the mesh, so that the user will feel cool when sitting on or leaning against the supporting structure.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 shows a conventional supporting structure for a swivel chair;
  • FIG. 2 shows a supporting structure for a chair in accordance with the present invention;
  • FIG. 3 is an exploded view of showing the frame and the mesh of the supporting structure for a chair in accordance with the present invention;
  • FIG. 4 is an enlarged view of a part of the mesh;
  • FIG. 5 is a cross sectional view of the frame and the mesh of the supporting structure for a chair in accordance with the present invention; and
  • FIG. 6 is a cross sectional view of the supporting structure for a chair in accordance with the present invention.
    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • The present invention will be more clear from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
  • Referring to FIGS. 2 and 3, a supporting structure 20 for a chair 10 in accordance with the present invention is a seat 20A, a back support 20B or a headrest 20C. The supporting structure 20 is provided with a frame 21, an annular flange 22 formed on the inner periphery of the frame 21, and a nylon mesh 23 (as shown in FIG. 5) is fixed to the top of the annular flange 22. The mesh 23 is formed with a plurality of apertures 24 (as shown FIG. 4). A plastic-injection-molded annular engaging portion 25 is integrally formed on the outer periphery of the frame 21 and enables the mesh 23 to be firmly fixed on the frame 21, as shown FIG. 6.
  • When the user sits on or leans against the mesh 23, the elasticity and the tension of the mesh 23 is used to absorb the impact force (or the load) caused by the user's buttocks, back and head, providing comfortable seating. Further, the apertures 24 make the mesh 23 breathable and the heat caused by the user's body can be vented off via the apertures 24, providing a cooling effect.
  • Therefore, the present invention has the following advantages as compared to the prior art:
  • The support structure 20 is a seat 20A, a back support 20B or a headrest 20C. The nylon mesh 23 is fixed on the annular flange 22 of the frame 21, and then the plastic-injection-molded annular engaging portion 25 is integrally formed on the outer periphery of the frame 21, enabling the mesh 23 to be firmly fixed on the frame 21. The elasticity of the mesh 23 provides a comfortable and adequate support for the user's buttocks, back and head, providing comfortable seating and preventing muscle soreness. Further, the heat caused by the user's body can be vented off via the apertures 24, so that the user will feel cool.
  • While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
