Structure of a mesh supporting frame of a mesh chair and assembly of the mesh chair

Abstract

A mesh chair includes a mesh supporting frame, and a mesh positioned over and joined on the mesh supporting frame; the mesh supporting frame has several joining post portions spaced apart on a loop-shaped side thereof; the mesh is stretched to a tense state and joined on the mesh supporting frame with the joining post portions of the frame being passed through the openings on the periphery thereof; afterwards, a wrapping layer is formed over and around the joint between the mesh and the mesh supporting frame by injection molding to join the mesh and the mesh supporting frame together; thus, the mesh is firmly joined on the mesh supporting frame, having such a tension and elasticity as to provide supporting force to a sitter on the mesh chair.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an assembly structure of a mesh and a mesh supporting frame of a mesh chair, more particularly one, which allows the mesh to be joined on the mesh supporting frame in a tense state; in assembly, the mesh supporting frame has joining post portions thereon, and the mesh is joined on the frame with the joining post portions being passed through openings of its periphery, and a wrapping layer is formed over the joint by injection molding.[0003]2. Brief Description of the Prior Art[0004]People's demand for high quality products is increasing with heightening of living standard. For instance, besides being comfortable and designed according to ergonomics, chairs have to have a unique and novel appearance to attract consumers. A wide variety of chairs are available to meet people's need, e.g. stools, ottomans, office chairs, and leisure chairs. Mesh chairs are very comfortable and getting popul...

AI Technical Summary

Benefits of technology

[0014]A mesh chair in accordance with an embodiment of the present invention includes a mesh supporting frame, a mesh, and a wrapping layer firmly joining the mesh and the mesh supporting frame together. The mesh supporting frame has several joining post portions spaced apart on a loop-shaped side thereof, and the mesh is stretched to a very tense state and joined on the mesh supporting frame with the joining post portions of the frame being passed through openings on the periphery thereof. Afterwards, injection molding is carried out to form the wrapping layer over and around the joint between the mesh and the mesh supporting frame; thus, the mesh is firmly joined on the frame, having relatively great tension and elasticity as to provide sufficient supporting force and comfort to a sitter on the mesh chair.

Problems solved by technology

However, the first one of the above-mentioned chair backs has a drawback: the pressing strip can't firmly fix the cushion to the frame, and in turn the cushion can become loose after having been used a certain length of time.

And, the second one of the above-mentioned chair backs has a similar drawback: the periphery of the mesh is prone to move relative to the frames owing to the sitter's weight.

Consequently, the mesh will lose its tension, and become less comfortable after having been used for a certain length of time.

However, such chair seat / back takes relatively much time to assemble.

Consequently, the above-mentioned chairs aren't suitable for mass production.

However, they are found to have the following drawbacks: the mesh isn't in a sufficiently stretched state when injection molding is being carried out to form the wrapping layer.

Consequently, the mesh doesn't have enough tension and strength for allowing a sitter to be supported thereon comfortably.

However, it is relatively difficult to firmly join the mesh to the frame with high frequency wave hot-press method because the frame has an ergonomically curved shape.

Moreover, such a high frequency wave hot-press method consumes relatively much energy, and the mesh can be deformed by heat.

And, because the mesh and the frame are made of different materials, it is difficult to make both firmly joined together with heat of high frequency wave.
