[Prior art]

  A plastic sheet with many convex protrusions on the surface that form an independent air chamber. After the sheet (also simply referred to as a projection sheet) and the elastic foam sheet are superposed, a round bar Futon in which a plurality of single cores wound in a shape are connected in parallel The core material for use has already been proposed by the present inventor as an excellent health promoting effect. (Jitsuko Sho 50-17706). This futon core is made by the massage effect. Although it is excellent in improving health, it feels a little cold in winter when used all year round. It was tactile and could not be said to have sufficient heat retention. Also, the futon core is static It is easy to take up dust, so dust and dirt easily adhere to it to keep the futon clean. Was difficult.

[0003]   In order to improve the heat retention and the chargeability of the above futon core material, a part of the core core is made of gold. Futon in which a metal-deposited film or a core body provided with a metal foil is wrapped in a futon bag. Is also proposed by the present inventor (Japanese Utility Model Publication No. 1-15391, etc.). But This futon is still sufficient in terms of heat retention and touch when actually used. I couldn't say.

[0008]   The present invention will be described in detail with reference to the accompanying drawings.   FIG. 1 and FIG. 2 respectively show an embodiment of a single core used for the futon of the present invention. It is a cross-sectional view and a vertical sectional view shown.

[0009]   In FIGS. 1 and 2, the core unit 1 includes a mandrel 2, a projection sheet 3, and a projection sheet. Far-infrared reflecting material 4 provided at one end of 3 with a desired width, and the back of the projection sheet 3. And a layered body composed of elastic foam sheets 5 that are provided so as to overlap almost the entire surface. Has been. The projection sheet 3 has a large number of independent air chambers 6 on its surface, So that the air chamber 6 of the projecting sheet 3 projects outward, so that the air space 6 around the mandrel 2 is overlapped. Is also wrapped around. The far-infrared reflecting material 4 extends over the outermost layer of the single core 1 over almost half the circumference. It is arranged. The outer edge 7 of the laminated body is fixed by a fixing means 8 such as a pressure sensitive tape. At least temporarily fixed.

[0010]   The mandrel 2 has rigidity such as wood, metal and plastic material. A rod or a pipe made of a hard material or a rubber material having elasticity is used. The shape of the mandrel 2 may be cylindrical, cylindrical or prismatic. In general, single core It is desirable to be able to sufficiently reinforce the body 1 and at the same time be lightweight, and use a hollow pipe. Is advantageous. Specifically, polyethylene, polypropylene, polyvinyl chloride Pipes made of hard plastic such as Nil or ABS resin, and light such as aluminum A pipe made of metal is preferred.

[0011]   The dimensions of the mandrel 2 can be variously changed according to the purpose. For example, of mandrel 2 The length may be the same as the length of the single core 1, but as shown in FIG. It is preferably slightly shorter than the length of the body 1. This will remove the mandrel from the core alone. Suitable for storing futons on both ends of the core, and for convenient futon spreading. The degree of cushioning can be imparted. Cushion part 9 without the mandrel 2 Is generally in the range of 1 to 60 mm, and the diameter of the mandrel 2 is generally 5 to 50 mm. The range is mm.

[0012]   The projection sheet 3 is a plastic sheet having a large number of convex projections formed of independent air chambers on its surface. A sticky sheet, which is described in, for example, Japanese Utility Model Publication No. 50-17706. The plastic film with a large number of protrusions and the flat plastic Laminated sheet made of plastic obtained by fusing or adhering the film Is preferred.

As the plastic film forming the protrusion sheet 3, for example, a thermoplastic resin such as polyethylene, polypropylene, polyvinyl chloride, polyester, or polyamide is used. This plastic film may be subjected to a suitable surface treatment for reducing air permeability, or may be laminated with another film having low air permeability. The thickness of the plastic film is in the range of about 30-300 μm. The size of the convex projection of the projection sheet 3 is not particularly defined, but the height of the projection is generally in the range of about 3 to 20 mm, preferably in the range of 5 to 15 mm. The bottom area of the protrusions is in the range of about 0.03 to ³ cm ² , preferably 0.1 to ² cm ² .

[0014]   The far-infrared reflector 4 is made of a metal having a high heat ray reflectance and a high thermal conductivity. Vapor-deposited metal films and metal foils are used. Preferably aluminum vapor deposition Film and aluminum foil. Copper, gold and their metals Vapor-deposited films such as gold, and foils of these metals can also be used. Far infrared The line-reflecting material 4 is simply placed on the end of the back surface of the projection sheet 3 with an appropriate width so as to be overlapped with each other. However, it is preferable that the end of the back surface of the projection sheet 3 is previously attached with an adhesive or the like. Stick them together. As a result, the creeping property of the end portion of the protruding sheet 3 is improved, and Air in the standing air chamber 6 is less likely to escape, and handling is easier. Change In addition, the surface of the projection sheet 3 having the convex projection is reflected by far infrared rays such as a metal vapor deposition film. It may be formed of the material 4. Specifically, the surface having convex protrusions is made of aluminum or the like. It can be formed by a method such as vapor deposition of metal.

[0015]   The far-infrared reflector 4 provided on the single core 1 reflects far-infrared rays from the human body. Both keep the temperature uniform, which improves the heat retention. In addition, the projection sheet 3 is not charged. The core unit 1 acts so as to prevent dust and dirt from adhering thereto. further , Even if the projection sheet 3 slides, no rustling noise is produced.

[0016]   As the elastic foam sheet 5, foam rubber, foam polyurethane, foam polybutadiene Foamed elastomers such as resins are preferably used. These are ordinary open-cell type Alternatively, it may be a closed cell type. Also, polyethylene foam sheet Plastic such as polyvinyl chloride foam sheet, polystyrene foam sheet, Soft foam sheets can also be used. The elastic foam sheet 5 is located on a part of the back surface. The projection sheet 3 provided with the infrared reflecting material 4 is overlaid on almost the entire back surface. This In this case, it is not generally necessary to perform a special joining process between the two, but if desired, it is possible. The two may be joined together by means such as an adhesive or heat fusion.

[0017]   The multilayer body composed of the projection sheet 3, the far infrared ray reflecting material 4 and the elastic foam sheet 5 is The mandrel 2 is used as a winding core so that the air chamber 6 of the protruding sheet 3 is on the outside. It is wrapped in layers. In this case, between the mandrel 2 and the protruding sheet 3 of each layer Since the elastic foam sheet 5 having cushioning property and large friction is interposed, the mandrel is It is possible to wrap both sheets around the circumference of 2 substantially and securely. Therefore, the dimensional stability of the formed core simplex 1 can be significantly improved. Also , Inside the core unit 1, air gaps in which air can freely flow in and out are largely excluded. Therefore, it is possible to prevent excessive temporary deformation and permanent deformation of the core unit 1 itself. It These advantages are further enhanced by the mandrel 2 being reinforced.

[0018]   Needless to say, the projection shield provided with the far-infrared reflecting material 4 on the back surface and / or part of the front surface. The elastic foam sheet 5 is superposed on the surface of the air bag 6 having the air chamber 6 5 is on the inside and the back surface of the projection sheet 3 or the far infrared reflecting material 4 is on the outside. It is also possible to wind these around the mandrel 2.
