Abstract

(57) [Summary] [Purpose] A chair that is lightweight and has cushioning and breathability. [Structure] A plurality of glass fibers 6 are hung over a front and rear joint frame 4 of a chair at a predetermined interval to form a seat portion 10, and a plurality of glass fibers 7 are hung at a back frame 5 at a predetermined interval. By passing it over, the backrest portion 11 is formed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a chair which is used for furniture or office work and is suitable as an interior article.

[0002]

[Prior Art]

 Conventional chairs used for furniture and the like require cushioning properties. Therefore, a cushion spring such as an S spring is stretched over the frame, and a cushion pad with elasticity is attached to this cushion spring. , Its seat and back were constructed. Alternatively, cushioning properties are provided by packing cushioning materials inside the backrest and seat.

[0003]

[Problems to be solved by the device]

 Since the chair of the conventional structure uses cushioning as its design point, the structure is complicated and it is not possible to reduce the weight, and assembly is also troublesome. In addition, although the cushion pad has a cushioning property, its breathability is poor, and the body part in contact with the cushion pad during use for a long period of time was distorted or sweated, which caused discomfort.

The present invention has been made in consideration of the above circumstances, has a simple structure and can be reduced in weight, is easy to assemble, is excellent in design, and has sufficient cushioning property and breathability. The purpose is to provide a chair.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is characterized in that at least the seat portion and the backrest portion are constructed by tensioning a plurality of glass fibers, and a predetermined distance is maintained between the glass fibers. I am trying.

[0006]

[Action]

 Glass fibers are used as various industrial materials such as electrical insulating materials and heat insulating materials, and have appropriate flexibility and mechanical strength despite their light weight. The seat portion and the backrest portion, which are formed by tensioning the glass fibers at a predetermined interval, have sufficient cushioning properties, breathability, and a comfortable sitting feeling. Moreover, the weight of the chair as a whole can be reduced.

【Example】

 FIG. 1 shows an embodiment of the present invention, in which a main frame is composed of a support frame 1 that abuts on a floor surface and four leg frames 2 that stand upright from the bent portions and end portions of the support frame 1. Is configured. Each of the two front leg frames 2 is bent inward and then hangs downward, and its lower ends are connected to each other by a front joint frame 3. Further, the two front leg frames 2 and the two rear leg frames 2 are connected to each other by parallel front and rear joint frames 4 which are slanted downward toward the rear. The support frame 1, the leg frame 2, the front joint frame 3, and the front and rear joint frames 4 are made of stainless steel or the like and are made of a lightweight and rust-resistant metal. Further, each of these frames 1, 2, 3 and 4 has a rectangular cross section, which provides safety and aesthetics. In the figure, reference numeral 5 denotes a back frame that connects the inner front / rear joint frame 4 and the rear leg frame 2 and is formed of the same material and the same shape as the frames 1, 2, 3, and 4. In the illustrated example, the back frame 5 is provided so as to be inclined rearward.

In addition to such a configuration, a plurality of glass fibers 6 and 7 are stretched over the seat portion 10 and the backrest portion 11, respectively. The glass fiber 6 of the seat portion 10 is hung in parallel between the inner front and rear joint frames 4, and the glass fiber 7 of the backrest portion 11 is hung between the back frames 5. The glass fibers 6 and 7 are stretched over the respective frames 4 and 5 while maintaining a predetermined space between the glass fibers 6 and 7, so that the seat portion 10 and the backrest portion 11 are breathable. Has been granted. The distance between the glass fibers 6 and 7 is selected so that the cushioning property is not impaired, moderate flexibility is imparted when seated, and strength that can withstand use is imparted.

FIG. 2 shows a state in which the glass fiber 6 is suspended in the seat portion 10, and the glass fiber 7 in the backrest portion 11 is also suspended in the same configuration. The glass fiber 6 in the seat portion 10 is formed with an insertion hole 8 corresponding to the front and rear joint frame 4 inside, and the glass fiber 6 is inserted into the insertion hole 8 so that both ends of the glass fiber 6 contact the inner surface 4a of the front and rear joint frame 4. By doing so, it becomes a crossover state. When a load at the time of sitting is applied in this suspended state, the load is bent as shown by a broken line, and this bending gives cushioning properties at the time of sitting. In such a bent state, since the glass fiber 6 itself has a certain degree of strength, both ends thereof do not come out of the front and rear joint frame 4. Therefore, the glass fiber 6 can be bridged simply by inserting both ends into the insertion holes 8 of the front and rear joint frame 4, and no special processing or treatment is required to prevent the glass fiber from coming off. Therefore, there is a merit that the assembly is extremely easy. Further, since a plurality of glass fibers 6 are stretched at a predetermined interval, the seating load is distributed to the plurality of glass fibers 6 and is not locally concentrated on a specific glass fiber. There are no defects or breaks. Further, since the distance between the glass fibers 6 and 7 has a predetermined distance, the seat portion 10 and the backrest portion 11 are provided with breathability, and the feeling of sitting is also comfortable.

By stretching the glass fibers 6 and 7 on the seat portion 10 and the backrest portion 11 as described above, the lightweight properties of the glass fibers 6 and 7 are imparted to the chair, and the entire chair can be made lightweight. At the same time, the straight line feeling of the glass fibers 6 and 7 improves the aesthetics, and it is possible to make a functional chair with excellent design.

In FIG. 1, reference numeral 9 denotes a glass fiber stretched on the armrest portion. The glass fiber 9 of the armrest portion facilitates a sitting posture, but the glass fiber 9 is optional. If it is not necessary, it may be omitted.

[0012]

[Effect of the device]

 According to the present invention, the glass fiber is stretched to form the seat portion and the backrest portion of the chair, and the predetermined distance is maintained between the glass fibers. Therefore, the weight of the entire chair can be reduced. Assembling itself is easy, and yet cushioning and breathability are sufficiently imparted, and it is possible to provide a new chair that has a novel design and is unprecedented.
