Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an electric heating sheet that has an improved structure for attaching the main body of the heating sheet to bedding.

[Technical background of the invention]

For example, an electric bed blanket that is placed on top of a futon is generally used with a heat generating sheet body removably covered by a cloth bag-like cover. However, this poses a problem in that when the user turns over while sleeping, the heat generating sheet body becomes lopsided within the cover. Therefore, in recent years, a device has been proposed in which a string fixed to the heat generating sheet body and a string fixed to the inside of the cover are fastened together to fix the heat generating sheet body to the cover.

[Problems with background technology]

However, even with the above-described configuration, both the strings of the heat generating sheet body and the cover may come undone during use, causing the heat generating sheet body to become lopsided within the cover due to turning over during sleep, or the strings may not come undone. In both cases, since the cover was not fixed to the mattress, there was a problem in that the main body of the heat-generating sheet could shift along with the cover, causing it to shift to one side.

[Purpose of invention]

An object of the present invention is to provide an electric heating sheet that can securely fix the heat generating sheet body together with the cover to bedding and prevent the heat generating sheet body and the cover from shifting.

[Summary of the idea]

In the present invention, strip members are provided on both sides of the heat generating sheet body, through holes are formed on both sides of a cover removably attached to the heat generating sheet body to cover the heat generating sheet body, and the strip members are inserted into the through holes of the cover. It is characterized in that both the heat generating sheet main body and the cover are fixed to the bedding by the strip members by guiding it outward through the heating sheet and winding it under the bedding and fixing it.

[Example of idea]

An embodiment in which the present invention is applied to a so-called electric bed blanket will be described below with reference to FIGS. 1 to 4. First, in FIGS. 1 and 2, reference numeral 1 denotes a substantially rectangular heating sheet main body, which has flexible heating wires 2 arranged in a meandering manner inside. Reference numeral 3 designates four strip members, which are band-shaped and have flexibility, and one end of which is sewn to each side of the long side of the heat generating sheet body 1, two each. There is. 4 is a cloth cover,
This has a substantially rectangular bag shape, houses the heat generating sheet main body 1 therein, and is removably attached to the heat generating sheet main body 1 to cover the heat generating sheet main body 1. On both sides of the long side of this cover 4, there are holes 5 that penetrate vertically at four places corresponding to the strip members 3 of the heat generating sheet main body 1.
a and a hole 5 that communicates this hole 5a with the inside of the cover 4.
A through-hole 5 is formed, and furthermore, an insertion hole 6 is formed on the outer side of each through-hole 5 and extends vertically through the through-hole 5 (see FIG. 3). The other end of the strip member 3 of the heat generating sheet body 1 is guided upwardly and outwardly from inside the cover 4 through the through hole 5 of the cover 4, and is further inserted into the through hole 6 from above to below. . On the other hand, in FIG. 4, reference numeral 7 indicates a mattress serving as bedding, and a heat generating sheet main body 1 covered with a cover 4 is placed on the top surface of this mattress. Then, the four strip members 3 inserted through the insertion holes 6 of the cover 4 and extended are inserted under the mattress 7 so as to be wrapped around the mattress 7 in a taut state, and the mattress 7 is attached to the floor surface etc. It is fixed in such a way that it is pressed down.

According to the above configuration, even if the user turns over on the mattress 7 during use, since the strip members 3 are fixed to the mattress 7 side, there is no risk of the heat generating sheet main body 1 shifting. Further, since the cover 4 is also pressed and fixed to the mattress 7 via the heat generating sheet body 1 and the strip members 3, there is no risk of it shifting when the user turns over in bed. In addition, when sleeping, the weight of the person acts on the strip members 3 through the mattress 7 and the pressing force becomes even stronger, so the strip members 3 are securely fixed and prevent the heat generating sheet body 1 and the cover 4 from shifting. can be prevented. This prevents the heating sheet main body from shifting and wrinkling when the user turns and turns, which would damage the internal heating wires, which is the case in the prior art.

In this embodiment, the other ends of the strip members 3 are pressed against the bottom surface of the mattress 7, but the present invention is not limited to this, and the strip members 3 are fastened to each other on the bottom surface of the mattress 7. You can. Further, as shown in FIGS. 5 and 6, fixing devices 8 such as so-called magic tape are provided on both sides of the cover 4 and the strip member 3 in the vicinity of the through hole 5, and the fixing devices 8 are used to secure the strip member 3. 3 may be fixed to the side of the cover 4 and then wrapped around the mattress 7.

[Effect of idea]

As described above, the present invention provides strip members on both sides of the heat generating sheet body, and also forms through holes on both sides of a cover removably attached to the heat generating sheet body to cover the strip members. It is characterized by a structure in which the heat-generating sheet body and the cover are guided outward through the through-holes of the cover, and then wrapped around and fixed to the underside of the bedding. This has the effect of being able to be fixed and prevent the heat generating sheet main body and cover from shifting and shifting even when, for example, one turns over in bed.
