STRUCTURE OF COMBINING MESH SEAT WITH CHAIR FRAME}

The present invention relates to a mesh seat chair and a structure for coupling the seat to the chair frame. The present invention is a technology that can be easily secured by assembling the mesh sheet to the seat frame of the mesh chair by separating and accommodating the separated frame on both sides of the mesh seat.

A chair made of mesh (mesh) material with a back or seat plate is generally called a mesh chair. The mesh chair is a chair loved by hot summers or our country's summer season due to its good ventilation.

Until now, mesh chairs have been formed using a square or a round pipe to form a seat frame of a back plate or a seat plate (hereinafter referred to as a seat and a seat) in a circle, oval or rectangle, and then stitched with a mesh cloth. To make a sheet, and the sheet thus made is assembled by assembling a screw or the like to the seat support frame of the chair.

However, this method has to go through the process of welding, etc. in the fabrication of the frame, and the stitching must be carried out while the mesh cloth on the frame is pulled tightly, so that the workability is bad and the defect rate is high, and when the tension is loosened, it is difficult to repair it again. There is a problem.

In addition, the Registered Patent Publication (Registration No. 10-794225, Registered by Jan. 2008, Jang Kwan-young, Patent Holder Duoback Korea, hereinafter referred to as the 'Patent of Cheong Gwan Yong') issued by the Korean Intellectual Property Office The structure of the seat cushion unit and the seat frame is disclosed. The invention also relates to the bending of a pipe having a certain length having a circular or elliptical cross section by a bending device so as to have appropriate bends in accordance with the required shape of the seat. And both ends are joined by welding or the like, and the above conventional frame is used.

The invention for the vas deferens also takes a method of fixing the end of the mesh to the gap of these supports using the inner and outer pipe-like support, but a circular ring-shaped elastic member for the separate fixing and securing elasticity (symbols of the above specification; There is a problem in that the production cost is high because the number of parts using 12) and the elastic material is used to secure the tension (the above line and Figures 2 to 5).

The present inventors have developed the present invention to solve the above problems.

An object of the present invention is to provide a mesh sheet and its coupling structure by a sheet frame that does not require welding, such as welding.

Still another object of the present invention is to provide a mesh sheet and a coupling structure thereof that are easy to assemble and repair while easily securing tension.

Still another object of the present invention is to provide a mesh sheet and a coupling structure thereof, which reduces assembly labor and manufacturing cost with a small number of parts.

Another object of the present invention is to provide a mesh sheet of various shapes with the above purpose.

The first to third objects are mesh seat meshes, wherein the mesh seats 10 and 30 are screwed to the seat receptacles 1 and 3 formed by opposing seat support frames 12 and 14 as described in claim 1. In the sheet bonding structure, the mesh sheets 10 and 30 have both sides of the mesh sheet coupled to a second coupling portion coupled to the other side 14 'opposite to the first coupling portion coupled to one side 12' of the seat frame. Separately formed in, the first and second coupling parts are basically achieved by separately receiving the first coupling frame 12 and the second coupling frame 14, respectively.

In addition, the structure of claim 2, that is, in addition to the first, the second coupling portion, the third, fourth coupling portion and the third, the fourth coupling frame formed in the remaining opposite sides to further accommodate the tension can be secured in all directions have.

The assembly hole (h) for fitting the coupling frame to the coupling portion is formed at one end of each coupling portion, but if the mounting portion (s') is formed on the side so that the coupling frame can be seated after the coupling operation during assembly work Since the frame does not fall out, the workability is improved, and when used, the mesh cloth is prevented from coming off and the tension is secured.

When the shape of each coupling frame is curved, the last problem can be achieved.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in Figure 1, the embodiment of the present invention made the frame of the chair with a pipe, the seat receiving portion (1, 3) for accommodating the mesh sheet (10, 30) was formed on the back and seat.

The seat accommodating part (1,3) is a female threaded coupling hole (5) penetrating the inner side from the outside of the sheet support frame (12 ', 14') so that the mesh sheet according to the present invention can be screwed with a sheet coupling frame ( 12, 14) (the support of the shape shown in the present specification is also referred to as a 'combination frame' for convenience) is formed at a position corresponding to the through hole 15 for screwing.

Next, looking at the mesh sheet of the present invention, by folding both ends of the mesh sheet in a direction parallel to the left and right sides so that the coupling frame (12, 14) can be inserted into the left and right sides of the mesh sheet, the mesh sheet coupling frame receiving portion ( 1, 3, and the mesh frame is completed by inserting the coupling frame (12, 14), the screw coupling hole (5 ') is formed in the receiving portion (1, 3).

When the mesh sheet is completed, the mesh sheet is aligned with the seat receiving portions 1 and 3 and assembled to the seat support frames 12 'and 14' using the screws 5, until the tension is reached as much as desired. Tighten to complete the assembly.

Therefore, as shown in Figure 1, the width (A ') of the mesh sheet should be made slightly smaller than the inner width (A) of the sheet receiving portion to ensure the tension.

When forming the assembling holes of the coupling frame (12,14) as shown in Figure 2, but only part of the side contacting the seat support frame (12 ', 14') to form a seating portion (s'), when assembled, the mesh cloth is peeled off during use Can prevent losing.

3 further forms the third and fourth coupling parts 122 and 124 to secure tension in all directions, and further uses the third and fourth coupling frames 22 and 24 to support the third and fourth sheet support frames ( 22 'and 24' are shown.

4 illustrates a method of completing a mesh sheet by stitching a mesh end by enclosing a joining frame, rather than a method of inserting a joining frame to form a joining groove formed in advance, in which case the joining frames 12 and 14. It can be fully enclosed, so that the working frame does not move out of the coupling part without moving out of the working part, thereby improving workability.

In the present embodiment, only the shape of the mesh sheets 10 and 30 are rectangular, but may be various shapes such as circular or elliptical. In this case, the sheet supporting frames 12 'and 14' and the coupling frames 12 and 14 may be assembled by bending the same shape into a desired shape.

In addition, in the present embodiment, although the shape of the support and the coupling frame of the sheet using a square pipe, it is also possible to use a round or oval, of course.

In addition, in the present embodiment, since the user is seated properly seated in the chair is a seat coupling structure that combines only the left and right, it is not a commonly used lattice pattern used a structure having a strong tensile force in one direction.

Therefore, when making a sheet with a pulled structure from all directions, it is possible to use a general lattice pattern, but any may be used.

The example described above is a representative embodiment of the present invention, it is obvious that those skilled in the art can be freely modified within the equivalent range, it is also natural that these ranges fall within the scope of the present invention.
