Description

  The present invention relates to a grip member with an electric heater used for a grip of a motorcycle, a snowmobile or the like.

  A synthetic rubber grip of a handle of a motorcycle, a snowmobile, or the like used in a cold region may have a built-in heating wire that warms the grip as shown in Patent Document 1, for example. In this case, it is known that a heating wire is spirally wound in a groove of a synthetic resin core, and then the periphery is molded and covered with synthetic rubber.

US Pat. No. 4,990,753

  However, in the grip member of Patent Document 1, since the heating wire is wound in the groove, the surface is not flat. There is a problem that it is necessary to mold the synthetic rubber thickly so that the uneven shape is not transmitted to the surface of the synthetic rubber, and it is difficult to transmit heat from the electric heater wire to the hand.

  The objective of this invention is providing the grip member with an electric heater which eliminates the above-mentioned problem, makes the surface of the core main body at the time of attaching a heater flat, and can make conduction efficiency favorable.

  In order to achieve the above-mentioned object, the technical feature of the grip member with an electric heater according to the present invention is that a spiral flat groove portion having a predetermined width is formed on the surface of a synthetic resin core body made of a cylindrical body. In the groove portion, a plate-like metal conductive plate having the same width as that of the flat groove portion is embedded, and a current is passed through the metal conductive plate to generate heat.

  According to the grip member with an electric heater according to the present invention, it is possible to easily mold the synthetic rubber by flattening the surface of the core body by disposing the metal conductive plate in the flat groove portion engraved in a spiral shape. It is easy to transmit the calorific value to the hand.

The present invention will be described in detail based on the illustrated embodiments.
FIG. 1 is a perspective view of an embodiment, and a core body 1 that is a skeleton member of a grip is formed into a cylindrical shape by a synthetic resin material, for example, and a ring-shaped portion 2 is provided at the base end of the core body 1. The guide portion 3 is formed in the shape portion 2 to support a power supply line to be described later. A spiral flat groove portion 4 is formed on the outer surface of the core body 1. In addition, the core main body 1 may combine two semicylindrical members into one cylindrical member.

  In the longitudinal direction of the core body 1, a feed line lead-in groove 5 for wiring a feed line for supplying electricity to a metal conductive plate, which will be described later, is formed deeper than the flat groove portion 4, and other than the flat groove portion 4 of the core body 1. A large number of holes 6 are formed in this portion.

  The guide portion 3 is provided with an electric wire guide groove 7, and the electric wire guide groove 7 is formed in a U shape around the direction changing portion 8. Further, on the outer surface of the direction changing portion 8, an anti-slip ridge 9 is provided in the longitudinal direction of the core body 1.

  FIG. 2 shows a perspective view of a state in which a band-shaped metal conductive plate 11 is embedded along the flat groove portion 4, and this metal conductive plate 11 is obtained by processing, for example, a SUS (stainless steel) plate having a thickness of about 30 μm into a band shape. It is embedded in the flat groove portion 4 and is fixed to the core body 1 at both ends. In this fixing, the pin 12 protruding from the core body is inserted into the hole provided in the metal guide plate 11, and the head of the pin 12 is melted by heat after the insertion.

  A feed line 13 having two core wires from the outside is laid in the feed line drawing groove 5 of the guide portion 3, and one of the two core wires is a metal conductor plate in the vicinity of the ring-shaped portion 2. 11 is connected by soldering or the like. Further, the power supply line 13b having the other core wire is extended long, and before the metal conductive plate 11 is embedded in the flat groove portion 4, it is drawn into the power supply line drawing groove 5, and the metal conductive plate 11 is attached to the end thereof. After that, it is soldered to the end portion of the metal conductive plate 11.

  The feed line 13 is inserted into the feed line drawing groove 5 and is turned around the direction changing portion 8 and pulled back 180 degrees in the original direction. Therefore, even if a pulling force or the like is applied to the feed line 13 from the outside, the feed line 13 is supplied. The electric wire 13 is not pulled out due to the presence of the protrusion 9 or the like.

  FIG. 3 shows a longitudinal sectional view of the core body 1 on which the metal conductive plate 11 is disposed, in a state where the synthetic rubber 21 is molded by injection molding and the inner and outer surfaces are covered. At this time, the synthetic rubber 21 is well molded on the inner and outer surfaces through the hole 6, has an electrical insulating function, the outer surface becomes a grip, and the inner surface becomes a non-slip when attached to the handle pipe. .

  The grip member manufactured in this way is used by being attached to a handle pipe of a motorcycle or the like. When a current is passed through the metal conductive plate 11 through the feeder line 13, the metal conductive plate 11 generates heat, and the user's hand is warm.

It is a perspective view of a core body. It is a perspective view of the state where the electric heater was spirally wound around the core body. It is a longitudinal cross-sectional view of a state where synthetic rubber is molded on the core body.
