Description

Detailed Description of the Invention

[0001]

[Industrial field of application] The present invention relates to a cushion used for a chair or a chaise lounge during a sports field appearance battle.

[0002]

2. Description of the Related Art Conventionally, when a chair is dirty, it is neat to sit in a clean and firm chair with a handkerchief or to lay a newspaper. Even if I brought a cushion, it was dirty and it was a burden to bring and take it home.

[0003]

The above-mentioned methods have the following drawbacks. 1) There was nothing to wipe even if the chair was dirty. When I wiped it with a handkerchief, I was troubled by the location of the dirty handkerchief. 2) My body (especially my buttocks) hurt when I sat in a hard chair for a long time. 3) There was a problem that trousers were stained with printing ink when laid with newspaper. 4) In winter or in the case of light rain, if you sit in a chair you want to sit for a long time, your body may get cold or get wet.

[0004]

As a result of intensive research to solve the above problems, the present invention has been achieved. That is, the present invention has a nonwoven fabric or natural fiber on at least one side and a soft side on the other side. It is made of polyurethane foam sheet or cotton and has a space between them.
In a cushion with at least two layers, the periphery is sewn except for the entrance (the part where the hand can enter). In a cushion with at least two layers, the periphery is sewn except the entrance (the part where the hand can enter). Then, the surrounding sewn cushion is turned upside down, and a hand-removing cord is provided at the entrance (free entry / exit) so that even in the case of light rain, a cushion with at least two layers can be attached to the necessary part around the seat. With a cushion sewn with a synthetic resin film that can hold any height, put your hands through the entrance that is made up of two or more layers, wipe the dirt on the chair with the non-woven fabric or natural fiber woven surface, and lower the dirt removal part. Use soft polyurethane foam or cotton surface as the seat, and use the two-layer space as a bag and put empty cans, newspapers, and lunch boxes in the trash, or in the case of light rain, Rainwater prevention film simultaneously sewing machine sewing to the main site, connected by a body tie, is a multi-purpose cushion to prevent the penetration of rain water into the pants.

The present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a cushion of the present invention. For example, a non-woven fabric 1 is placed on a soft polyurethane sheet 2 having a predetermined length, and a folded back cut side end 9 is sewn with a sewing machine 6. FIG. 2 is a perspective view of a cushion of the present invention, which is obtained by turning over FIG. What is turned upside down is that two to four sewing end portions occupy the volume and the volume becomes three-dimensional, which is effective in expanding the volume of the bag body. Apart from that, if the sewing part of the sewing machine is visible, the product value is inferior.

FIG. 3 is a perspective view of a double-layer cushion having a soft polyurethane foam sheet 2 for the front portion (display portion, seat portion) 5 and a nonwoven fabric for the back portion 5a (not shown) of the present invention.
It is the cushion which turned inside out. By turning the inside out, the sewing sewing end 6a contributes to the expansion of the space of the bag K. The non-woven fabric forming the back surface is one in which a hand is put in from the entrance to wipe off dirt on the non-woven fabric surface in order to prevent soiling of chairs and the like. You can add color by drawing your favorite letters and pictures on the surface 5.
The display is changed depending on the opponent of the stadium such as "Hibiki Rokko Oroshi" and "GO GO Tigers". The entrance portion 8 leaves a portion where sewing machine sewing 6 is not performed in only one direction, but the bag portion K has a sports newspaper, a player table,
If it is cold in winter, insert a disposable body warmer to prevent the cold.

FIG. 4 is a perspective view of a cushion C having a three-layer structure. There are two bag portions K having a three-layer structure, and different types of bags can be inserted. FIG. 5 shows a cushion having a four-layer structure, which has three bag portions K, and three types can be inserted. A four-layer cushion is made by placing a non-woven fabric 1 of the same shape on a flexible polyurethane foam sheet 2, folding it back at half the length, and sewing the cut-side end 9 except for the inlet 8 with a sewing machine. Then, insert a hand from the entrance and turn it over to make a four-layer cushion.

6 and 7 show another example of the cushion of the present invention.
For example, in the case of a cushion on a baseball field, FIG. 6 is a plan view of the shape of a baseball, and FIG. 7 is a cushion shaped like a home base. FIG. 8 is an example of a cushion in a rugby field or an American football ball field.

FIG. 9 shows an example of the cushion of the present invention, which is used during a light rain. A rainwater waterproof film 7 is placed on the sewing part 6 of the seat part 5 (display part, front part), and the rainwater waterproof film 7 is sewn on the sewing machine and stands upright at right angles to the chair along the body when raining lightly, and rainwater waterproof. A body tie 3a is provided at the end 7a of the film to tie the body. Then, the seat portion 5 is subjected to a water repellent treatment to prevent rainwater from penetrating from the back surface portion 5a (not shown).

10 and 11 show an example of a composite structure of the soft polyurethane sheet 2 used in the present invention. In FIG. 10, natural fibers 1a are bonded or flame-processed (frame laminated) on one side of the soft polyurethane sheet 2. In FIG. 11, natural fibers are bonded or flame-processed (frame laminating) on both surfaces of the flexible polyurethane foam 2. The natural fibers used in the present invention are preferably cotton, hemp, rayon, suf, etc., and hydrophilic ones.

FIG. 12 and FIG. 13 show a cotton 2a like natural fiber gauze, and one or both sides of which are sewn with a sewing machine to form a cotton sheet.

[0012]

[Function] A bag-shaped one having a two-layer structure to a four-layer structure is sewn in three directions in a sewing direction, a hand is put in from the entrance, and the non-woven fabric or natural fiber surface is used to clean the chair. The seat part (sewn with gauze etc.) functions as a cushion.

[0013]

EFFECTS OF THE INVENTION At least one layer is a non-woven fabric or a natural fiber, and the other layer is a cushion made of soft polyurethane foam sheet or cotton, which is finished in three directions by sewing, but not sewing. Put your hand in through the entrance, remove the dirt from the non-woven fabric (natural fiber), and sit with one soft polyurethane foam (cotton surface) side as the seating surface. When you no longer need it, you can use it as a seat aid, and when it is no longer needed, you can take an empty can back to the bag. In addition, since a rainwater prevention film is sewn on the sewing machine sewing part on the seat surface, when light rain falls, the rainwater prevention film is brought into close contact with the body and the body is tied with the string at the end,
It has become possible to prevent rain from seeping through the chair.
