Supporting structure for a chair
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.

Claims
1. A supporting structure for a chair comprising: a frame, forming
an outer periphery of said supporting structure, having an inwardly
projecting flange with an annular upper surface; a mesh fixed at an
outer periphery thereof to said annular upper surface of said
flange, a plurality of apertures being formed in the mesh; and an
engaging layer, integrally formed on the mesh-covered upper annular
surface and on an exterior surface of the frame, thereby firmly
fixing the mesh to the frame.
2. The supporting structure for a chair as claimed in claim 1,
wherein the supporting structure is a seat.
3. The supporting structure for a chair as claimed in claim 1,
wherein the supporting structure is a back support.
4. The supporting structure for a chair as claimed in claim 1,
wherein the supporting structure is a headrest.
5. The supporting structure for a chair as claimed in claim 1,
wherein the mesh is made of nylon.
6. The supporting structure for a chair as claimed in claim 1,
wherein said engaging layer is an injection-molded plastic layer
covering the mesh-covered upper annular surface and the exterior
surface of the frame, thereby firmly fixing the mesh to the frame.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] 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.
[0003] 2. Description of the Prior Art
[0004] 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.
[0005] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages.
SUMMARY OF THE INVENTION
[0006] 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] 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.
[0014] 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.
[0015] 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.
[0016] Therefore, the present invention has the following
advantages as compared to the prior art:
[0017] 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.
[0018] 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.
