Description

  The present invention relates to a cushion.

  2. Description of the Related Art Conventionally, as a cushion used for sitting or the like, a cushion material inserted between front and back fabrics is known. By sitting on the upper surface of this cushion, the lower body of the seated person is prevented from touching the floor directly so that cold air from the floor can be blocked.

  However, in the conventional cushion, only the body part of the part where the lower body is in contact with the surface of the cushion can be kept warm. It was necessary to cover with.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a cushion having higher heat retention than a conventional cushion.

  In order to solve the above-mentioned problem, the device of claim 1 has a main body part and a cover part, and a part of the outer edge part of the main body part and a part of the outer edge part of the cover part are sewn together, A space is formed between the main body and the cover, and the space communicates with the outside through the opening.

  The device according to claim 2 is characterized in that, in the device according to claim 1, the outer edge portion of the main body portion is sewn into contact with the outer edge portion of the cover portion in more than half of the circumferential direction.

  According to the present invention, a space is formed between the main body portion and the cover portion, and this space is communicated with the outside through the opening portion. By being inserted so as to be positioned inside, it is possible to keep warm so as to wrap and cover the part of the inserted body, and it is possible to improve the warmth as compared with the conventional cushion.

The perspective view of the cushion of this invention. The side view of FIG. The longitudinal cross-sectional view of the state which lifted the opening side of the cover part. The perspective view which shows an example of the use condition of the cushion of FIG. The perspective view which shows the other example of the use condition of the cushion of FIG.

  The form for implementing this invention is demonstrated based on figures.

  The cushion 1 of the present invention includes a perfect circle main body 2 and a perfect circle cover 3. The shapes of the main body 2 and the cover 3 are not limited to a perfect circle as shown in the figure, and can be formed in an arbitrary shape such as an ellipse or a square.

  The main body 2 is composed of an outer cloth 2a constituting the outer surface thereof and a cushion material 2b filled in the outer cloth 2a. The cover part 3 is comprised by the outer fabric 3a which comprises the outer surface, and the cushion material 3b with which this outer fabric 3a was filled.

  A part of the outer edge 2c of the main body 2 in the circumferential direction and a part of the outer edge 3c of the cover 3 in the circumferential direction are sewn together. It is preferable that the outer edge portion 3c of the cover portion 3 is sewn into contact with the outer edge portion 2c of the main body portion 2 in more than half of the circumferential direction of the outer edge portion 2c. Thereby, a space 4 is formed between the main body 2 and the cover 3, and the space 4 communicates with the outside through the opening 5.

  The outer cloths 2a and 3a of the main body part 2 and the cover part 3 can be made of any cloth. As the cloth of the outer cloth 2a, 3a at least where the user touches, a cloth having high heat retention is preferable.

  Arbitrary members such as cotton and polyurethane foam can be used as the cushion materials 2b and 3b of the main body 2 and the cover 3, but polyurethane foam is used in this embodiment.

  The cushion 1 can be used by the user by inserting a portion of the body to be warmed, for example, the entire lower body as shown in FIG. 4 into the space 4 from the opening 5. When the user inserts the lower half of the body or the like into the space 4 at the half or more of the outer edge of the main body 2 in the circumferential direction, when the user inserts the lower body or the like into the space 4, the clearance between the space 4 and the outside is reduced. It can be made small and heat retention can be improved.

  Moreover, since the lower body of the user can be covered so as to be wrapped by the main body 2 and the cover 3, the contact area between the cushion 1 and the user can be increased as compared with the conventional cushion, and heat insulation is achieved. Can increase the sex. Further, when the lower body or the like is inserted into the space 4, the space 4 communicates with the outside only by the opening 5, so that the gap between the space 4 and the outside can be reduced and the heat retaining property can be improved.

  In addition, when the heat retaining property is not so required, as shown in FIG. 5, the user can lie down or sit on the upper portion of the cover portion 4 and use it.

  Further, since polyurethane foam is used as the cushioning materials 2b and 3b, the cushion 1 has a high form-retaining property, and the cushion 1 can be leaned against a wall or the like and leaned against it to be used as a backrest. ing.
