Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric cushion in which a cushion sheet in which a heating element that generates heat by energization is embedded is covered with a bag-like outer material.

[0002]

2. Description of the Related Art Electric cushions that can warm the body when sitting down are widely used in homes and offices. As this electric cushion, a cushion sheet of an appropriate shape and size is formed of urethane foam or the like, a heating element that generates heat by energization is buried inside the cushion sheet, and the outer periphery thereof is covered with a cloth bag outer material. There is something. The electric cushion has a structure in which the bag-like outer material covering the cushion sheet is completely closed.

[0003]

According to the electric cushion described above, the bag-like outer material covering the cushion sheet is completely closed.
For example, if the bag-shaped outer material becomes dirty or torn, the bag-shaped outer material cannot be removed from the cushion sheet for washing or repair. For this reason, when trying to protect the electric cushion from dirt and damage, there is a problem that a protective cover for covering and protecting the electric cushion must be made at home.

It is an object of the present invention to provide an electric cushion in which a cushion sheet is covered with a bag-like outer material, and the bag-like outer material is removed from the cushion sheet to enable washing and repair of the bag-like outer material. It is in.

Another object of the present invention is to provide an electric cushion with a cushion sheet covered with a bag-like outer material, and a bag-like outer material or a protective cover of a fixed-size cushion that is commercially available as bedding. , Which can be used as a bag-shaped outer material of a cushion sheet.

[0006]

In order to achieve the above-mentioned object, according to the first aspect of the present invention, there is provided an electric machine in which a cushion sheet in which a heating element which generates heat by energization is embedded is covered with a bag-shaped outer material. In a cushion, the bag-shaped outer material includes:
An opening having an opening / closing means enabling attachment / detachment to / from the cushion sheet is provided.

[0007] With this configuration, the bag-shaped outer material can be easily removed and attached from the cushion sheet. If the bag-shaped outer material becomes dirty or torn, the bag-shaped outer material is removed from the cushion sheet and washed. Can be repaired or repaired.

According to a second aspect of the present invention, the cushion sheet according to the first aspect is adapted to a bag-like outer material of a fixed-size cushion, which is commercially available as bedding, and the shape and size of the bag-like outer material can be attached. It is characterized in that it is formed at the same time.

[0009] With such a configuration, when the bag-like outer material covering the cushion sheet is soiled or torn, the bag-like surface material and the protective cover of a fixed-size cushion are commercially available as bedding. It can be used as a bag-shaped outer material of the cushion sheet, and a protective cover of a fixed-size cushion, which is commercially available as bedding,
It can be mounted as a protective cover of an electric cushion on the bag-like outer material covering the cushion sheet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an electric cushion according to the present invention will be described. In the drawings, reference numeral 1 denotes a cushion sheet in which a heating element 2 that generates heat by energization is embedded. In the present embodiment, the cushion sheet 1 is formed of urethane foam, but is not limited to this. In addition, the shape of the cushion sheet 1
In this example, in this example, the size and the size of the bag-shaped dressing are set according to the size of the bag-shaped dressing of a standard-size cushion that is commercially available as bedding.

[0011] Also. In the heating element 2 buried inside the cushion sheet 1 and generating heat by energization,
In this example, a nichrome wire is used. However, the present invention is not limited to this. For example, a planar heating element (PTC heater) using a positive temperature coefficient ink layer is also used as the heating element 2. 3 is a power cord.

Reference numeral 4 denotes a bag-like outer material covering the cushion sheet 1. The bag-shaped outer material 4 has an opening 5 through which the cushion sheet 1 can be inserted into and removed from the bag-shaped outer material 4. In this example, the opening 5 is provided on the side of the bag-shaped outer material 4, but may be provided on the front side or the back side. The opening 5 has opening / closing means 6 for opening and closing the opening 5. In this example, a zipper is used as the opening / closing means 6, but the opening / closing means 6 is not limited to this, and may be a button or a hook-and-loop fastener.

With this construction, the bag-shaped outer material 4 can be attached to and detached from the cushion sheet 1 by opening the opening 5 provided in the bag-shaped outer material 4, and putting the cushion sheet 1 into and out of the bag-shaped outer material 4. By doing so, when the bag-shaped outer material 4 is soiled or torn, the bag-shaped outer material 4 can be removed from the cushion sheet 1 for washing or repair.

The shape and size of the cushion sheet 1 are adjusted to the size of a bag-shaped outer material of a fixed-size cushion, which is commercially available as bedding, and the shape and size of the bag-shaped outer material are attachable. When the bag-shaped outer material 4 covering the cushion sheet 1 is dirty or torn, the bag-shaped outer material or protective cover of a standard-size cushion is commercially available as bedding. (Not shown) can be used as a bag-shaped outer material of the cushion sheet 1, and a protective cover of a fixed-size cushion is commercially available as bedding.
Can be attached as a protective cover of the electric cushion on the bag-like outer material 4 covering the cover.

[0015]

As described above, according to the electric cushion of the present invention, the bag-like outer material covering the cushion sheet has
Since the opening having the opening / closing means that enables attachment / detachment to / from the cushion sheet is provided, the bag-like outer material can be easily removed and attached from the cushion sheet, and the bag-like outer material becomes dirty or torn. In such a case, the bag-like outer material can be removed from the cushion sheet for washing or repair. Then, the cushion sheet is fitted to the bag-shaped outer material of a fixed-size cushion, which is commercially available as bedding, and is formed into a shape and size that can be attached to the bag-shaped outer material, whereby the cushion bedding is commercially available as the bedding. Can be used as the bag-shaped outer material of the cushion sheet, and the cushion-shaped cover of the fixed-size cushion that is commercially available as bedding. There is an effect that it can be attached as a protective cover of the electric cushion on the bag-like outer material covering the cover.
