Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to beds, and more particularly to beds that keep the bed warm.

[0002]

[Prior art]

 Conventionally, beds have been known to be adaptable to various uses such as sleeping for sleeping, emergency for carrying a suddenly ill person or an injured person, and work for easily getting in and out of a lower portion of a vehicle. There are some that are equipped with various mechanisms according to their respective applications. For example, beds for sleeping are provided with a cushion formed by embedding a metal spring in an elastic material such as sponge, and for emergency use, a cushion made of only an elastic material such as sponge is used as a plate. Beds are known that are arranged on the body and have legs provided with moving means such as casters under the body and elevating means for moving the plate body up and down with respect to the floor surface. Beds are known that are provided with moving means such as casters at the lower part of the bed.

However, although this conventional bed, in particular, an emergency bed and a work bed is mainly used outdoors or in a large factory exposed to cold air such as at night or in the winter, the bed itself does not respond to the cold air. No heating means.

Therefore, when the emergency bed is used, the body of a suddenly ill person or an injured person carried by the emergency bed is wrapped with a blanket, or when the work bed is used, the work bed is used outdoors. Workers wear heavy clothing, and in large factories, the number of heaters installed around is increased to reduce cold air.

However, in a method of carrying a body of a suddenly ill person or an injured person in a blanket when using an emergency bed, it is difficult for the injured person to maintain the body temperature because of a sudden decrease in body temperature due to whole-body burn or heavy bleeding. Moreover, when the body of the injured person is wet with rain or snow, the injured person's physical strength is exhausted, and death may result. In addition, the method in which the worker wears thick clothes when using the work bed has a drawback that he / she may get stuck and cause an accident, and the method of increasing the number of heating appliances not only significantly increases the utility cost but also actually There is a problem that if the temperature inside the factory is raised, the risk of causing an accident such as ignition of combustible materials such as thinner and gasoline will increase.

Further, when the work bed is used to enter the lower part of the vehicle for work, various electric appliances such as electric repair tools and work lights are often used. Has to pull multiple extension cords from a distant power source, which has the disadvantage of obstructing the work bed.

[0007]

[Problems to be solved by the device]

 The present invention is intended to solve the drawbacks of the conventional technique, and the purpose thereof is to avoid the need for the user to wear thick clothes when using the bed in the cold, such as at night or in the winter, and to avoid the surroundings. The purpose of the present invention is to provide a bed that can warm the user's body lying on the bed without having to increase the heating equipment in the bed, and a bed equipped with a power source for appliances used around the bed.

[0008]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned object, and its gist is that it is provided with a planar heating element and a heat storage material for storing heat generated by the planar heating element in a sleeping portion. It is in the dead.

Another aspect of the present invention resides in the above-mentioned bed, further comprising an outlet for obtaining power to the planar heating element.

As the sheet heating element used here, for example, a heating element in which a metal wire such as a nichrome wire is arranged so as to flow electric current, a copper paste, a silver paste, a nickel paste, an aluminum paste, carbon black, etc. A sheet on which a pattern-printed conductive paste or the like is printed, a sheet in which a resin in which carbon black is kneaded is impregnated into a cloth, a mixed paper sheet containing carbon fibers and pulp, a sheet in which the mixed paper sheet is impregnated with a resin, and an electric current is applied. It can be selected from a conductive metal foil body, a conductive paste, a carbon fiber-containing sheet heating sheet provided with a magnetic material, etc., but particularly stable temperature characteristics and mechanical strength, It is preferable to use a sheet heating element including a magnet material for at least a part of the carbon fiber-containing sheet heating sheet provided with a conductive metal foil for electricity and / or a conductive paste. preferable.

Further, the heat storage material can be constituted by laminating a plate of a metal or a light alloy such as aluminum with a polymer material such as wood, polyethylene, polypropylene, polyester or ENVI, or a metal powder. It can also be formed into a plate by mixing it with a polymer material, and can also be formed by depositing metal such as aluminum on a cloth by plating vapor deposition, or by adhering or applying powder such as ceramics by a method such as screen printing. You can also

[Action]

 In the bed of the present invention, heat is generated by the sheet heating element, and the heat is stored in the heat storage material to keep the bed warm. By providing the planar heating element with an outlet that has obtained power, the plurality of electric appliances used around the bed are collectively supplied with electricity.
