A chair seat includes a lower loop-shaped member, an auxiliary mesh, a loop-shaped pad part, and an upper mesh; the lower loop-shaped member encircles a first space; the auxiliary mesh is positioned over the first space and the lower loop-shaped member, and securely connected to the lower loop-shaped member at an edge; the loop-shaped pad part encircles a second space, and is secured over the lower loop-shaped member with the second space being right above the first space; the upper mesh is positioned over the second space and the loop-shaped pad part, and securely joined to a lower side of the lower loop-shaped member at an edge; the seat is positioned on top of and joined to a loop-shaped portion of a main unit of a chair at the lower loop-shaped member thereof so that the auxiliary mesh will help the upper mesh bear the sitter's body weight.
The present invention relates to a mesh seat of a chair, more particularly one, which is structured in such a way as to have more strength and be more comfortable to sit on.
A chair seat should be soft to be comfortable to sit on according to most people. Referring to FIG. 5, a conventional chair seat 3 includes a foam member 31, a lower plate 32, and a covering cloth 33. The foam member 31 is positioned over the lower plate 32, and both the foam member 31 and the lower plate 32 are wrapped in the covering cloth 33. The seat 3 is joined to a main unit 4 of a chair; thus, the chair has a soft seat. However, because air can't easily travel through foam, heat will accumulate at the seat 3, and the sitter will feel hot and uncomfortable at the buttock after having been seated on the chair for a period of time.
To overcome the above problem, another conventional chair seat 5 is provided as shown in FIG. 6, which includes a loop-shaped part 51, and a mesh 52. The mesh 52 is stretched to have a certain tension, and securely joined to the loop-shaped part 51 at an edge thereof so as to cover a space encircled by the loop-shaped part 51; thus, air can easily travel through the seat 5. And, the seat 5 is positioned on and securely joined to a main unit 6 of a chair.
However, the conventional mesh seat still has the following disadvantages:
1. The loop-shaped part has certain hardness such that the mesh, which is stretched to have certain tension, won't cause the loop-shaped part to change shape. Consequently, when a person is seated on the seat, he/she will feel discomfort owing to contact with the loop-shaped part.
2. Because the seat has single mesh with limited strength, the mesh will change shape after having been used for a period of time, and it is prone to break if a heavy person is seated on the seat.
It is a main object of the invention to provide a double-mesh seat of a chair to overcome the above-mentioned problems.
The double-mesh seat of the present invention includes a lower loop-shaped member, an auxiliary mesh, a loop-shaped pad part, and an upper mesh. The lower loop-shaped member encircles a first space. The auxiliary mesh is positioned over the first space and the lower loop-shaped member, and securely connected to the lower loop-shaped member at the edge. The loop-shaped pad part encircles a second space, and is secured over the lower loop-shaped member with the second space being right above the first space. The upper mesh is positioned over the second space and the loop-shaped pad part, and securely joined to a lower side of the lower loop-shaped member. The seat is positioned on top of and joined to a loop-shaped portion of a main unit of the chair at the lower loop-shaped member. Thus, the auxiliary mesh will help the upper mesh bear the sitter's body weight.
FIG. 1 is an exploded perspective view of the double-mesh seat and the main part of a chair according to the present invention,
FIG. 2 is a perspective view of the double-mesh seat and the main part in the present invention,
FIG. 3 is a sectional view of the double-mesh seat of the invention,
FIG. 4 is a partial sectional view of the chair according to the present invention,
FIG. 5 is a view of the first conventional chair seat, and
FIG. 6 is a view of the second conventional chair seat.
Referring to FIG. 1, a preferred embodiment 1 of a double-mesh seat of a chair includes a lower loop-shaped member 11, an auxiliary mesh 12, a loop-shaped pad part 13, and an upper mesh 14.
The lower loop-shaped member 11 encircles a space 110, and has several connecting holes 111 on a lower side thereof.
The auxiliary mesh 12 is positioned over the space 110 and the lower loop-shaped member 11, and securely connected to a lower side of the lower loop-shaped member 11 at an edge thereof.
The loop-shaped pad part 13 is made of soft materials such as foam to be comfortable to sit on, and it encircles a space 131. The loop-shaped pad part 13 is positioned over the lower loop-shaped member 11 with the space 131 being right above the space 110.
The upper mesh 14 is positioned over the space 131 and the loop-shaped pad part 13, and securely joined to a lower side of the lower loop-shaped member 11 at an edge thereof.
Referring to FIGS. 1 to 4, the double-mesh seat 1 is securely joined to a main unit 2 of the chair after it is assembled, which main unit 2 has a loop-shaped portion, which encircles a space 21, and has several connecting holes 22; the double-mesh seat 1 is positioned over the space 21 and the loop-shaped portion of the main unit 2, and screws are passed through the connecting holes 22 of the main unit 2 and into the connecting holes 111 of the lower loop-shaped member 11.
Thus, a space is provided under the double-mesh seat for receiving the buttock of a sitter, which is encircled by the double-mesh seat 1 and the main unit 2. And, if a heavy person is seated on the chair, the auxiliary mesh 12 will help the upper mesh 14 bear the body weight of the sitter.
From the above description, it can be easily seen that the present invention has the following advantages when compared with the conventional seats described in Background:
1. The double-mesh seat has a loop-shaped pad part 13 on top of the lower loop-shaped member 11 therefore it is more comfortable to sit on.
2. The double-mesh seat has the auxiliary mesh to help the upper mesh bear the weight of the sitter. Therefore, the upper mesh will have longer service life.
3. Air can travel through the seat easily because the seat has the upper mesh and the auxiliary mesh secured over the space encircled by the loop-shaped parts.
1. A double-mesh seat of a chair, comprising a lower annular member, the lower annular member encircling a first space;
an auxiliary mesh, the auxiliary mesh being positioned over the first space and the lower annular member, and securely connected to a lower side of the lower annular member adjacent an edge thereof;
