Description

  The present invention relates to a handle grip member with an electric heater used for grips of motorcycles, snowmobiles, and the like.

  Synthetic rubber grips for handles of motorcycles, snowmobiles, etc. used in cold regions or the like may incorporate an electric heater that warms the grip as shown in Patent Document 1, for example. In this electric heater, a sheet-like electric heating element in which a power supply line is electrically connected by soldering or welding is attached to the surface of a cylindrical synthetic resin core, and the periphery is made of synthetic rubber together with the core. Molded and covered.

  FIG. 2 is a perspective view showing a main part of a conventional grip member for a handle with an electric heater by the present applicant. A core body 1 serving as a skeleton member of a grip is formed into a cylindrical shape by a synthetic resin material, for example. A ring-shaped portion 2 is provided at the base end of 1. The ring-shaped portion 2 is formed with a drawing guide portion 4 that supports the power supply line 3, and the drawing guide portion 4 is provided with a guide groove 5. An electric heater 6 made of a metal foil is attached to the outer surface of the core body 1 through a power supply line 3.

  Then, synthetic rubber is introduced from the direction of the arrow into a mold (not shown) disposed on the inner and outer surfaces of the assembled core body 1 and electric heater 6, and the synthetic rubber is molded and covered by injection molding.

Japanese Patent Laid-Open No. 2006-76317

  However, in the above-mentioned handle grip member, the synthetic rubber flows into the guide groove 5 of the electric heater 6 and the power supply line 3 at the time of injection molding, so that the power supply line 3 itself is caused by the inflow pressure of the rubber from the drawing guide portion 4. There is a possibility that the outer side may come off or pressure may be applied to the connecting portion of the feeder 3 to the heater 6 to break the connecting portion.

  Therefore, it is necessary to provide separate parts for protection, and so-called short shots that weaken the molding pressure are likely to occur, and the productivity such as defect rate and yield is increased while taking complicated structure and labor. It ’s a bad problem.

  An object of the present invention is to provide a grip member for a handle with an electric heater that eliminates the above-described problems and does not cause a displacement in a power supply line due to an inflow pressure of synthetic rubber.

  In order to achieve the above object, a handle grip member with an electric heater according to the present invention has an electric heating element attached to the surface of a core body made of a cylindrical or semi-cylindrical body, and the longitudinal length of the core body of the electric heating element. In a grip member in which a feed line is connected to the direction end, a feed guide part for the feed line is formed at the end in the longitudinal direction, and a synthetic rubber for electrical insulation is molded, the draw guide part is formed of the synthetic rubber. The inflow side is opened, and a wall portion is provided on the opposite side.

  According to the handle member for a handle with an electric heater according to the present invention, by providing a wall portion on the opposite side of the guide portion for feeding the synthetic rubber, the feed wire is disconnected due to the inflow pressure, or the connection portion is broken. The risk of this can be greatly reduced, and the production yield can be improved.

The present invention will be described in detail based on the embodiment shown in FIG.
FIG. 1 is a perspective view of a main part of a handle grip member with an electric heater according to the present embodiment. A core body 11 serving as a skeleton member of a grip is formed into a cylindrical shape by a synthetic resin material, for example. A ring-shaped portion 12 is provided at the proximal end, and a pull-out guide portion 14 that supports the feeder 13 is formed in the ring-shaped portion 12.

  A guide groove 15 is provided in the drawer guide portion 14, and this guide groove 15 is formed in a U shape around the direction changing member 16, and the side into which the synthetic rubber flows is opened, and the flow of the synthetic rubber is on the opposite side. A wall portion 17 is provided for blocking the dam. In addition, an electric heater 18 is bonded to the outer surface of the core body 11 via a power supply line 13.

  After fixing the electric heater 18 on the core body 11, the feeder 13 is inserted into the pull-out guide portion 14, turned around the direction changing member 16, and pulled back 180 degrees in the original direction.

  Synthetic rubber is introduced from the direction of the arrow into the inner and outer surfaces of the core main body 11, the feeder 13 and the electric heater 18 assembled in this way, and the synthetic rubber is molded and covered by injection molding.

  The drawer guide portion 14 is opened on the side into which the synthetic rubber is introduced, and the wall portion 17 is provided on the opposite side. Therefore, even when the synthetic rubber flows into the guide groove 15, the feeder 13 is connected to the guide groove 15. There is no risk of being pushed out or causing displacement. On the contrary, the feeder 13 is firmly fixed in the guide groove 15 by the inflow pressure of the synthetic rubber.

It is a principal part perspective view of the grip member which pulled in the electric power feeding line in an Example. It is a principal part perspective view of the grip member which pulled in the conventional feeder.
