Description

[Detailed Description of the Invention] The present invention relates to a sponge body used as the inside of a seat cushion or cushion, which improves air permeability and allows adjustment of flexibility.

Sponges have already been used as the filling for seat cushions or cushions, but in the past, the edges of a plate-shaped sponge body of an appropriate size and thickness were cut off to give it a rounded edge. Although some methods include wrapping it in a thin sponge sheet, the sponge itself is still used as is.

Therefore, the flexibility of the anastomosis used as a seat cushion or cushion is determined by the flexibility of the sponge, which cannot be changed.

Furthermore, since the air inside the sponge has difficulty escaping, it tends to trap warm air, making it unsuitable for warm seasons.

In this case, a cut is made in a plate-shaped sponge body from its circumferential surface in a direction parallel to its width direction. The sponge body and the insert body are provided with holes penetrating them in the thickness direction, and the holes adjust the flexibility of the entire contents and improve breathability. It is characterized by making it possible to make the sponge body smooth and rounding the edges of the sponge body, and to reduce the labor required for processing the sponge body.

To explain the contents of the seat cushion and cushion of this proposal with reference to the embodiment shown in the drawings, 1 is a plate-shaped sponge body made of synthetic resin or rubber, and a cut 3 is provided from the circumferential surface in a direction parallel to the width direction of the sponge body 1. A portion of the sponge body 1 is divided into two in the thickness direction.

In this example, since the sponge body is rectangular, the cut 3 is formed in a portion excluding both ends of the - side, and is provided in a penetrating manner from the - side to the opposite side.

However, the cut 3 may be provided in a bottomed shape from one side to near the opposite side, or may be provided in a state that penetrates each of the four sides.

When the sponge body 1 is circular, cuts 3 are provided in an appropriate range on its circumferential surface.

Reference numeral 4 denotes a flexible insert such as a sponge, cotton, etc., which is inserted approximately in the center of the sponge body 1 which has been divided at the cut 3, and this is because it gives bulge to both the front and back sides of the sponge. , the center part of the sponge body 1 is thickened,
It is suitable to make the peripheral part thin, but when using a plate-shaped sponge, it is also possible to use one with the same thickness throughout, and in this case also, the peripheral part of the sponge that is the insert body 4 is strong. Since the sponge body 1 is pressurized and becomes thinner, both the front and back surfaces thereof become curved surfaces.

When using a sponge as the insert 4, it may be a plate or a chip, and in the case of a chip, it may be used by putting it in a bag.

Reference numeral 2 denotes a hole that penetrates both the sponge body 1 and the insert body 4 and is provided over almost the entire surface thereof.

The contents of this seat cushion, etc. are placed in the side of the futon made of cloth or other materials, and holes 2 are provided therethrough almost entirely in the thickness direction.

Therefore, if the density of the pores 2 is made high or the diameter of the pores 2 is made large, the elasticity of the sponge body 1 will be reduced and it will feel soft. Since the hardness of the sponge body 1 is close to its original hardness, it is possible to use the sponge body 1 with the same hardness to penetrate the contents with different hardness by simply changing the holes 2. It is possible to easily move between cushions of different sizes.

By providing the holes 2 in the hard sponge body 1, it can be made soft, so that its restoring force after pressurization has the same restoring force that the sponge body 1 originally had, and has a long life. Reduces deformation due to repeated use.

Since the holes 2 are provided to penetrate the sponge body 1 in its thickness direction, air inside the sponge body 1 or the insert body 4 will flow through the holes 2 no matter which side of the sponge body 1 is used facing upward. It flows out of the seat cushion etc. through it, or vice versa.

That is, the air inside the sponge body 1 circulates in and out of the seat cushion, etc., and heat is not easily trapped, so it can be comfortably used even in the warm season.

The contents of this seat cushion etc. are made by cutting the plate-shaped sponge body 1 into 3.
Since the insert 4 made of sponge or other material is placed inside the tube or bag, the overall hardness can be changed by selecting the material of the insert 4, depending on the application. You can explore the contents according to your needs.

Then, the cut 3 of the cylindrical or bag-shaped sponge body 1 is
The insert 4 is inserted over almost the entire length of the opening, and the insert 4 expands the sponge body 1 and puts its surface under tension, making it possible to round the edges of the sponge body 1. You can make the contents look nice.

Since the sponge body 1 has a cylindrical or bag-like shape with cuts 3 made therein, it requires less effort than gluing the ends of two sponge plates together, and also eliminates problems such as peeling. It is possible to explore the contents with great strength.

Furthermore, since it is impossible for the insert 4 to move within the sponge body 1, deformation can be prevented and the usability can be improved.
