Description

[Detailed Description of the Invention] The present invention relates to a deformable sheet.

Conventionally, commercially available seats have been kept in a fixed shape, and when used by users of various body shapes, the seat may not adapt to the body shape or adapt to the resting position the user wants to take each time. However, the drawback was that it was not possible to get sufficient rest. Also, some sheets are filled with air, which can be deformed to some extent,
The state of deformation was unstable, making it impossible for the user to maintain a stable posture, and likewise not being able to take sufficient rest.

In this invention, by configuring a seat by storing a large number of elastic granular Styrofoam inside a bag made of a flexible material into a spherical shape, when a user sits on the seat, the seat is By configuring it so that it can transform into a state that fits the sitting posture of the user, it adapts to the resting position that the user wants to take, and stably maintains that posture, allowing for sufficient rest, and also has excellent heat retention. The aim is to provide sheets.

The embodiment of the present invention will be explained in detail based on the drawings.
A indicates a sheet, and the sheet A is composed of a large number of elastic granular Styrofoam 2 stored in a spherical bag 1 made of a flexible material. When the user 3 is seated on the seat, the seat A can be deformed to suit the sitting position of the user 3.

The bag body 1 may be formed of a flexible material such as natural leather, synthetic leather, etc., and the bag body 1 has a circular bottom skin 4, six elongated circumferential skins, and a circular upper skin. It is composed of leather 6, and its sewing condition is as follows.
The proximal ends of the circumferential skins 5 are sewn to the peripheral edge of the bottom skin 4, the circumferential skins 5 are arranged in a radial manner around the bottom skin 4, and the circumferential skins 5 adjacent to each other are The opposing longitudinal edges 5' are sewn together, and the tip of each circumferential skin 5 is sewn to the circumferential edge of the upper skin 6 to maintain the overall shape in a spherical shape. Further, a fastener 8 is provided at a desired position of the bag 1, so that the polystyrene foam 2 to be stored in the bag 1 can be taken in and out.

The styrofoam 2 has a diameter of around 10 mm, and the amount stored in the bag 1 is limited to about 2/3 of the maximum storage capacity of the bag 1, so that the entire seat A can accommodate the user 3 in the sitting position. It can be formed according to the requirements.

In addition, the Styrofoam 2 is stored in a net 7 that has almost the same shape as the bag 1, and then stored inside the bag 1 to prevent the Styrofoam 2 from coming out of the bag 1 even if the bag 1 is damaged. There is. At this time, if the size of the mesh of the net 7 is made slightly smaller than the diameter of the styrofoam 2, the styrofoam 2 can be connected to the net 7.
The Styrofoam 2 is caught in the mesh of the net 7, and the Styrofoam 2 is laid down along the inner circumferential surface of the net 7. Other Styrofoam 2 slides on the surface of the Styrofoam 2 in this laid state, and the flow is extremely smooth. The packed Styrofoam 2 is in a fixed state, and after other Styrofoam is embedded between the Styrofoam and flows, some Styrofoam remains in the recess and can exert a cushioning effect.

The present invention is not limited to the above-mentioned embodiment in forming the bag body 1, and may be formed in other ways, such as by sewing two gourd-shaped skins together, similar to the skins of official baseball balls. It may be hot.

The embodiment of the present invention is constructed as described above, and when the user sits on the seat A in a desired posture, the Styrofoam 2 flows within the bag body 1, and the seat A is placed in any posture of the user 3. The device can be deformed to fit the user's back and maintain the desired posture of the user. Also, Styrofoam 2
Since it has elasticity, it has a cushioning effect, and when pressure is applied when the user 3 is sitting, it deforms and becomes difficult to flow. does not deform and maintains a stable sitting posture.

Moreover, the foamed polystyrene 2 can maintain sufficient heat insulation effect and maintain excellent heat retention. Furthermore, by coloring the circumferential skin 5 in a different color, a colorful design can be achieved.

According to the present invention, by configuring a seat by storing a large number of elastic granular Styrofoam inside a spherical bag made of a flexible material, when a user sits on the seat, the seat remains in the same position. Since it is configured so that it can be deformed to fit the user's sitting posture, it adapts to the resting position the user wants to take, and it maintains its sister position stably, allowing for sufficient rest, as well as excellent heat retention. play.

Furthermore, in the present invention, since the Styrofoam is housed in a net that has approximately the same shape as the bag, it is possible to reliably prevent the Styrofoam from scattering outside the bag even if the bag is damaged.

In addition, since the size of the mesh of the net was made slightly smaller than the diameter of the Styrofoam, the Styrofoam was caught in the mesh of the net, and the Styrofoam was laid along the inner circumferential surface of the net, and the surface of the Styrofoam in this laid state was The styrofoam glides on and allows for extremely smooth flow. Therefore, the sheet can be smoothly deformed.

In this way, by storing the Styrofoam net with a small mesh inside the bag, the fluidity of the Styrofoam is improved, and the shape is easily adapted to the human body. Other foamed polystyrene is embedded in the cushion, and a certain amount of foamed polystyrene remains in the area after it has flowed, making it possible to support the cushioning effect even in areas that are depressed by the weight of a person.
