FIG. 2 shows the electric heater 2. In the figure, 3 is a lead wire, 4 is a waterproof switch with a thermostat, and 5 is a connection terminal.

By the way, the electric heater 2 is constructed by wiring an asbestos-coated electric resistance wire 8 on the inside of a base sheet formed by stacking a linen cloth 6 and a cotton cloth 7 as shown in FIG. A soft resin waterproof coating 9 is applied on top of it, and the mechanical strength (pulling, twisting, compression, etc.) when operating the handle while grasping it with the hand in actual use
Is not taken into consideration, and the asbestos-coated electric resistance wire 8 easily moves or breaks. Further, there are problems that the asbestos-coated electric resistance wire 8 is felt by the hand and is difficult to operate, and that heat escapes to the steering wheel to prevent quick heating.

Further, there is a method for processing a heating element unit as shown in FIGS. 12 to 14, but the purpose of this processing method is to heat and melt the synthetic resin sheet 24 and the cloth 25 merely for the purpose of fixing the heating wire 27. There is something.

This is basically different from the object of the present invention, and there is a problem that the resin sheet 24 and the cloth 25 become a major obstacle to the function of quickly transmitting the heat from the heating wire 27.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned conventional problems, and improves the mechanical strength and thermal conductivity of an electric heating wire and a heating unit having the electric heating wire. The purpose of the present invention is to obtain a vehicle handle that can be operated with various handles.

According to the present invention, in a vehicle handle having an electrothermal heat generating unit provided on the outer periphery of a handle, a heat insulating member is provided on the outer periphery of a core body via a synthetic resin member to form a handle body, and The sheet-shaped heat generating unit and the outer cover are sequentially stacked, and the heat generating unit is formed by sequentially stacking and sequentially fixing a metal layer, a heat-fusible resin layer, a heating element, and a metal layer from the handle body toward the outer cover. Characterized by
Since the resin coating member is provided on the inner surface of the metal layer to fix the heating wire, and the heating element is configured by resin tubing on the heating wire, the assembly of the heating unit becomes stable by the above configuration, and The surface is soaked by the metal layer and the rapid heating property is improved, and heat can be prevented from escaping to the handle body by the heat insulating material.

In FIG. 4, reference numeral 10 denotes a handlebar body of the automobile,
As shown in FIG. 5, the handle body 10 includes a core 11 made of metal and a synthetic resin member 12 molded on the outer periphery thereof.
And the heat insulating material 13 adhered to the outer periphery thereof. As shown in FIG. 6, a sheet-shaped heat generating unit 14 is attached to the outer periphery of the handle body 10, and an outer cover 15 is attached to the outer periphery of the heat generating unit 14. As shown in FIG. 7 and FIG. 8, the sheet-shaped heat generating unit 14 includes a metal layer (aluminum foil or the like) 16 made of a metal layer and a heating element 17 fixed to the inner surface of the metal layer 16. The inner surface of the layer 16 is coated with a low melting point soft resin material such as polyethylene, and the heating element 17 has a high melting point soft resin such as heat resistant vinyl chloride resin, silicon resin or fluorine resin outside the heating wire 20 as shown in FIG. An inner skin 21 made of a material is provided, and a heat melting resin layer having a melting point lower than that of the inner skin 21, for example, an outer skin 22 made of polyethylene resin is provided on the outer side thereof. The heating element 17 heats the outer skin 22 and is welded to the inner surface of the metal layer 16 coated with the low melting point soft resin material.

Although the outer skin structure of the heating element 17 is a double tubing structure in the embodiment, only the inner outer skin 21 may be used as long as heat welding can be completed. Furthermore, when the adhesion between the metal layer 16 and the heating element 17 is mechanically insufficient, it is also necessary to reinforce the metal layer 16 with a metal layer (such as aluminum foil) 18. In the embodiment, the metal layer 16, the heating element 17, and the metal layer 18
In order to heat-bond the and, a low-melting heat-meltable resin layer (polyethylene or the like) 19 is used to fix them.

Further, the heating unit 14 finishes the surface of the metal layer 16 to be smooth, and processes the surface of the metal layer 18 so as to leave the convex portion of the heating element 17.

The handle body 10 has a thin synthetic resin member 12 molded for easy grip. Also,
In order to endure the twisting force and the pulling force when operating the handle, some adhesive is used between each layer of the heat insulating material 13, the heat generating unit 14, the outer skin 15, etc. to partially fix or receive the maximum force. The portion may be reinforced with a binding yarn or the like, or the whole may be strongly tightened with the binding yarn 23 used for the outer cover 15. Further, between the pitches of the wired heating elements 17, a foamed resin such as urethane or a vinyl chloride resin containing carbon or other silicone resin having good thermal conductivity and having a hardness such that the heating elements 17 do not float on the surface, It is preferable that the heating element 17 does not float on the surface of the outer skin 15. Further, as shown in FIGS. 10 and 11, the heating element 17 may be any zigzag wiring in the circumferential direction of the handle body or along the circumference. Further, as shown in FIG. 15, the heating element 17 may be partially arranged instead of the entire handle.
