  The invention described in Patent Document 1 is a mattress with a built-in coil spring, where the position of the mattress is harder than the other part as necessary, that is, the body is more difficult to sink than the other part, This part is designed so that the user's back and buttocks lying on the mattress can sink in the correct posture, making it difficult to sink as necessary. However, the bed of the present invention only proposes a method for locally adjusting the elastic force of the coil spring.

  In the invention described in Patent Document 2, a plurality of liquid-tight bags are arranged on the upper surface of a lower surface material composed of a frame using urethane foam and the like, a waterproof liner and a lower cover, and water or gel-like material is placed inside the bag. It is related with the improvement of the bed which accommodated fluid substances, such as. The present invention also provides a user whose body weight is dispersed and the bed is easily moved.

  However, the inventions described in Patent Documents 1 and 2 use a small amount of heat to slightly reduce the body temperature by slightly heating the foot or slightly cooling the shoulder near the neck. It does not suggest a simple device to adjust and make the human body lying on the bed comfortable.

  The present invention eliminates the drawbacks of the prior art described above, and does not give any deformation to the bed structure, and uses a temperature control sheet having a simple structure to control the temperature of the so-called “head cold / foot heat”. The object is to provide a bed that enables the method.

  In order to achieve the above object, a mattress body for a bed according to the present invention is configured as follows.

1. In a mattress body formed by laminating a temperature control sheet on at least one surface of a mattress constituting a bed, the temperature control sheet is filled with a planar heating element having PTC characteristics and a heat storage material stacked thereon. This is a bed mattress body that is formed of the heat storage material sheet and is used by positioning the temperature control sheet on the head side or the foot side in relation to room temperature.

2. The heating element constituting the temperature control sheet is a planar heating element having a PTC characteristic, and the heating part is formed as an aggregate of strips by cutting a thin space between two electrode wires. It is characterized by that.

3. The heat storage material sheet constituting the temperature adjusting sheet is characterized in that it is filled with a heat storage material that changes its phase to a liquid state by heating and is subdivided into a number of sachets.

4). The temperature control sheet is characterized in that it is configured by combining a heat storage material having a characteristic that is easily maintained at a temperature of about 32 ° C. ± 1 ° C. and a planar heating element having a PTC function.

5. A temperature control sheet composed of a heat storage material sheet filled with a heating element and a heat storage material laminated thereon is arranged on both sides of the mattress to form a three-layer structure, and wrapping all of these members with a finishing material It is characterized by the construction.

  In the present invention, the temperature control sheet formed by laminating the heating element and the sheet-shaped heat storage material is arranged on one or both sides of the mattress to form the mattress body of the bed. Place on the foot side, energize the heating element of this temperature control sheet to sufficiently store heat in the heat storage material, and transfer a large amount of heat from the heat storage material to the feet, especially the ankle, for comfortable heating in a short time Do.

  And in the summer, the cold air is stored in the temperature adjustment sheet by cooling the room, and when the sleeping position is put on the bed, the temperature adjustment sheet comes in contact from the neck to the shoulder, and it feels comfortable as `` cool '' The user can easily fall into a sleep state.

  In general, mattresses prevent mattresses caused by a decrease in elastic force due to fatigue caused by burdening some coil springs. The mattress life is improved by turning the mattress upside down and turning it upside down. The operation is extended.

  Therefore, in order to cope with the reversing operation of the mattress, the entire temperature regulation sheet is placed in the bag with the mattress being placed on the top and bottom of the mattress, so that the bed can be adjusted in the above-described manner. Life expectancy can be achieved.

  Briefly explaining the basic principle of the present invention, the body temperature of a human body when sleeping using a quilt is about 30 ° C. for an adult. This sleeping state is the state in which the heat radiation from the body is the most reduced. Therefore, if there is a heat source that can be heated to about 2 ° C. to 3 ° C. with respect to this body temperature, it feels warm, and conversely, a predetermined temperature range with respect to body temperature In other words, if there is a cooling source with a temperature as low as 32 ° C. ± 1 ° C., it can be felt cold. The present invention has been obtained based on the knowledge that a person can feel comfortably by a slight temperature difference (± 1 ° C.) with respect to the body temperature. That is, a comfortable bed is to be constructed by using a slight amount of heat when a person sleeps.

  FIG. 1 is a perspective view showing a main part (the illustration of a frame part is omitted) of a bed 3 in which temperature control sheets 2 are arranged on both front and back surfaces of a mattress 1 used in a normal bed.

  The temperature adjustment sheet 2 is configured by arranging a temperature adjustment body 4 between a plurality of cushion sheets 3 and 3 having heat retention properties. The mattress 1 and the temperature control sheet 2 are arranged on one or both sides of the mattress 1 and the whole is wrapped with a bag-like finishing material (adjusted at a bed manufacturing factory) and can be handled in the same manner as a normal bed. It is configured to be able to.

  FIG. 2 is an enlarged cross-sectional view of the main part of the bed 3 shown in FIG. 1, and the temperature control sheet 2 is a temperature control body between cushion sheets 3 and 3 made of foamed urethane having a thickness of about 30 mm. 4 is arranged, and the upper surface is covered with a cloth finishing material 5 described below, and the lower surface is covered with a moisture-proof sheet 6 to form a thin mattress or thick blanket.

  FIG. 3 shows a cross-sectional view of the temperature control sheet 2, in which the temperature control body 4 is wrapped with a cushion sheet 3 made of urethane foam, a finishing material 6 is disposed on the upper surface side, and a waterproof sheet 6 is disposed on the lower surface side. As a whole, a laminated sheet is formed.

  FIG. 4 is a plan view showing the main part of the temperature control sheet 2. The temperature control body 4 is disposed in a portion where a foot is placed in winter and is disposed in a portion where a head is placed in summer. Is. The dimensions are related to the dimensions of the mattress 1 to be used. For example, the temperature control body 4 has a width A of about 500 mm and a length B of about 900 mm (single bed) and 1800 mm (double bed). It is a size that can be placed from the shoulder to the back of the person.

  This temperature control sheet 2 is composed of a planar heating element 8 having PTC characteristics and a latent heat type heat storage material 9. The planar heating element 8 uses a planar heating element (product name: plastic heat) for floor heating manufactured and sold by Misato Co., Ltd. (Satte City, Saitama Prefecture) to which the present inventor belongs. Among these planar heating elements, a flexible heating element (sudder heater: a narrow heating element arranged in parallel between two electrodes) makes the user feel irritated It is better not to give a sense of discomfort.

  In addition, as shown in FIG. 5, the heat storage material forms a bag body with a heat-resistant and electrically insulating sheet, and has a melting point of 31 ° C. to 33 ° C. (32 ° C. ± 1 ° C.) inside. The heat storage material 10 is accommodated and formed into a mat shape, which is divided into small bags b as shown in FIG. As this heat storage material, it is preferable to use a material having a melting temperature within the above-mentioned range among sodium sulfate decahydrate (Na2SO4 · 10H2O).

  The temperature range takes into account the temperature difference between soft and cold in the body temperature of adult men and women, and it feels as described above by a slight temperature difference (about 1 ° C) centered on 32 ° C. It is.

As described above, the heat storage sheet 10 is divided into a plurality of small rooms by partitioning the heat storage sheet 9 into a small bag shape (performing ultrasonic bonding or the like from the top of the bag body) to form a small bag b. And since the heat storage material 10 which is in a liquid state by a slight heating is confined in the sachet b, the sachet 10 has a soft feeling of elasticity due to the confined liquid, which is a pillow. Comfortable cushioning will be given even under the shoulder, under the shoulder, or under the foot. Considering the amount of latent heat possessed by the heat storage material 10 and the state of heat that the human body feels comfortable, the amount is preferably in the range of 1.5 to ² kg / m ² .

  FIG. 6A shows a cross-sectional shape of the mattress body 13 of the completed bed. The mattress body 13 is provided with the temperature control sheets 2 shown in FIGS. 2 to 4 on the top and bottom and both sides of a mattress 1 having a normal structure. And the whole is put in the cloth-made cosmetic bag 12 (finishing material), and is integrated.

  The reason why the temperature control sheets 2 are arranged on the upper and lower surfaces and both surfaces of the mattress 1 as described above is as follows. That is, the mattress 1 has a large number of coil springs installed therein, and when the weight of the human body is added to the same position, the elastic force gradually decreases due to a metal fatigue phenomenon, and a portion that sinks deeply occurs. . Therefore, in order to avoid this phenomenon, a maintenance method is generally adopted in which the position of the front and rear is rearranged after a predetermined period of use of the mattress has passed, and then the mattress 1 is inverted and further the position is changed back and forth. The present invention is to cope with this maintenance method. Therefore, the temperature control sheet 2 only needs to be disposed on one side of the mattress 1 when the top and bottom are not reversed.

  According to the present invention, since the temperature control sheet 2 is disposed on the part where the foot is placed in winter, the planar heating element 8 built in the temperature control sheet 2 for several hours before using the bed. By energizing (FIG. 3) and applying sufficient heat to the heat storage material 9 to store the heat, it is possible to quickly heat the foot with a sufficient amount of heat at the beginning of sleep.

  In summer, when a user lies on the mattress body 13, the temperature control sheet 2 is positioned from the neck to the shoulder. As described above, since the heat storage material 9 is maintained at a room temperature or lower, the heat absorption by the heat storage material 9 gives a cool feeling during the summer, and the user can sleep comfortably.

  In FIG. 6, 14 is an electric operation part provided at the end of the mattress 1, and this electric operation part 14 includes a power switch, a power switch indicator lamp (light emitting diode), a timer (about 4 to 10 hours), There are temperature setting switches and emergency indicator lights for selecting strong, medium and weak. In addition, the method of connecting the power cord to the outlet connected with the electrode of the sheet heating element 8 uses an electromagnet for the purpose of facilitating the rotation and reversing operation of the mat portion 13 and preventing a leakage accident. preferable.
