This kind of corner pole is composed of a telescopic pole consisting of a plurality of pipes with different diameters. When not in use, it is shortened by a driving device to avoid breakage etc. and can be stored in the bumper There is something. In addition, this type of corner pole incorporates a light source inside the pole and turns on the light source so that the pole can be easily visually recognized even at night.

[0003] Such an electric telescopic corner pole is disclosed in, for example, Japanese Utility Model Application Laid-Open No. 60-193612 (hereinafter referred to as Prior Art 1) and Japanese Utility Model Application Laid-Open No. 6-75893 (hereinafter referred to as Prior Art 2). Something was done.
The corner pole disclosed in Prior Art 1 has a structure in which a drive cord pushes or pulls a drive cord in a length direction to extend and retract the pole.

[0004] The drive cord is an electric wire whose core wire is insulated and covered with a synthetic resin, and teeth are engraved in a rack shape on the surface of the covering material, and a pinion is meshed with the teeth. Therefore, when the pinion is rotated by the drive motor, the drive cord can move in the length direction to extend or shorten the pole.

[0005] Power is supplied to the light source using a drive cord. That is, the core wire of the drive cord is connected to the anode terminal of the light source, a connection member made of a conductive material is connected to the power source, and the connection terminal is connected to the terminal of the core wire (the end opposite to the light source) corresponding to this connection member.

Reference numeral 1 denotes a cylindrical member made of a conductive material, through which the other end of the insulating cord 3A is inserted. A contact piece 64 is fixed to the outer peripheral surface of the fixed contact member 61 by a set screw 65. The contact piece 64 is electrically connected to an anode terminal of a power source (battery, not shown) via an external cord 66 (see FIG. 1). The core wire 3a of the insulation cord 3A-
The other end of 1 forms an uncoated portion H by removing the coating material 3a-2, and the movable contact member 62 is movably mounted on the uncoated portion H. The movable contact member 62 is formed in a cylindrical body by a conductive material, and the inner diameter is set smaller than the outer diameter of the coating material 3a-2. For this reason, the movable contact member 62 is made of the coating material 3a-
It does not move to the part covered by 2. Also, a ring 6 made of a conductive material is attached to the other end of the core wire 3a-1.

To extend the pole 2, the drive motor 3
4, the gear 42 is rotated clockwise in FIG. As a result, the drive cord 3 is sent from the case 35 to the pole storage cylinder 50 side, and pushes up the pole 2. Therefore, the pole 2 extends and projects above the bumper 58. When the drive cord 3 moves, the movable contact member 62 also moves integrally with the drive cord 3, so that the fixed contact member 6 immediately before the pole 2 almost completely projects.
1 to compress the compression coil spring 63. Therefore, the switch means 33 switches to the ON state. FIG.
Indicates this state. This allows the current from the battery to
External code 66-fixed contact member 61-movable contact member 62
-Compression coil spring 63-Ring 67-Core wire 3a-1-Terminal member 19-Compression coil spring 18-Terminal member 28-Lead terminal 29-Resistance 21-Lead 27-Supply to anode terminal 25 via conductive plate 22 and light source 6 is turned on.

In order to shorten the pole 2 and store it in the bumper 58, the drive cord 34 may be driven in the opposite direction to retract the drive cord 3 into the cylinder 60.
As a result, the pole 2 is shortened and stored in the pole storage cylinder 50. Further, the movable contact member 62 is
As a result, the switch 33 is turned off and the light source 6 is turned off.

In the motorized telescopic corner pole 1 having such a structure, the drive section 4 and the pole storage section 5 are formed separately, and the drive section 4 is rotatable with respect to the pole storage section 5 and is detachable. When the drive unit 4 is mounted upside down with respect to the pole storage unit 5, the position of the drive unit 4 with respect to the pole storage unit 5 is changed from the position indicated by the solid line in FIG. Can be shifted to the position indicated by. Therefore, the degree of freedom of attachment to the bumper 58 is increased, and attachment to various bumpers is possible.

In the above-described embodiment, an example has been described in which the driving section 4 is mounted horizontally on the pole storage section 5. However, the present invention is not limited to this, and the driving section 4 may be mounted vertically. Further, the concave portions 47 and 48 and the convex portions 54 and 55
