[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractable automobile corner pole which is attached to a corner portion of an automobile so that a driver of the automobile can check the width of the automobile.

[0002]

2. Description of the Related Art Conventionally, a corner pole for an automobile of this type uses an expandable telescopic pole having a light emitting element such as a light emitting diode attached to the upper end thereof, and pushes out a drive cord passing through the inside of the multistage pole. By doing so, the entire pole is extended, and on the contrary, the drive cord is pulled in to reduce the scale. Further, as a means for supplying power to the light emitting body, a pole itself composed of an electric wire passing through the inside of the drive cord and a conductive metal tube is used.

A top assembly including a light emitter and a top lens covering the light emitter is mounted on the uppermost pole, and inside the pole, electric power is supplied to electrically connect the electric wire passing through the inside of the drive cord to the light emitter. The mechanism is incorporated.

[0004]

However, in the above-mentioned conventional example, since water enters the top assembly from below the multi-stage pole due to evaporation or the like and easily becomes water droplets due to temperature change, electrical components are corroded in the top assembly. Doing so or adversely affecting the optical system.

For this reason, in the past, countermeasures using grease or the like have been taken, but sufficient effects have not been obtained. SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to provide a corner pole for an automobile, in which a sealing member is used to prevent the water that has entered the pole from entering the top assembly.

[0006]

SUMMARY OF THE INVENTION To achieve the above object, an automobile corner pole according to the present invention is a top assembly including a retractable multi-stage pole and a light emitter attached to the upper end of the multi-stage pole. A corner pole for an automobile having a drive cord in which an electric wire for driving the multistage pole is inserted in the multistage pole, in a corner pole for an automobile, between a metal sleeve provided around the top assembly and the drive cord. It is characterized in that a substantially cylindrical seal member made of an elastic material is arranged in the.

[0007]

The vehicle corner pole having the above structure is
A seal member seals the space between the drive cord and the metal sleeve that holds the top assembly to prevent moisture and the like from entering the top assembly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the illustrated embodiments.

FIG. 1 is a sectional view of the embodiment, and FIG. 2 is a perspective view showing a state in which the top assembly A is removed from the multistage pole B. The top assembly A includes a light-emitting body 1 such as a light-emitting diode, an inner lens 2 made of a transparent synthetic resin, which is arranged above the light-emitting body 1 and has a plurality of notches 2a formed on the outer periphery thereof
A transparent synthetic resin top lens 3 that wraps the outside of the light emitter 1 and the inner lens 2, a lens cap 4 screwed onto the upper end thereof, an earth metal 5 to which one terminal 1a of the light emitter 1 is connected, and this earth metal 5 The insulator sleeve 6 located below, the insulator sleeve 6 and the top lens 3
A metal sleeve 7, which is provided around the lower part of the
It has a conductive spring 8 which is built in the insulator sleeve 6 and presses the earth metal 5.

The terminal 1b on the other side of the light emitting body 1 is wound around a half groove along the groove on the outer circumference of the top lens 3 and is in contact with the metal sleeve 7. The metal sleeve 7 and the top lens 3 and the metal sleeve 7 and the insulator sleeve 6 can be fixed by an adhesive method or the like.
It is easy to punch and stop several points like P1 and P2.

On the other hand, the lower portion of the insulator sleeve 6 is incorporated inside the uppermost pole 9 of the multi-stage pole B, and the cord stopper metal 11 fixed to the tip of the drive cord 10 is inside the insulating sleeve 6 below. It enters and is in elastic contact with the conductive spring 8. Drive code 1
The tip of the wire 12 that passes through the inside of
1 is electrically connected to the light emitting body 1 through the conductive spring 8 and the ground metal 5.

At the bottom of the insulating sleeve 6, a substantially cylindrical seal member 13 made of an elastic body having a circumferential annular groove 13a on its lower surface is provided to seal between the metal sleeve 7 and the drive cord 10. And is fixed by a stopper 14 having a circumferential projection 14a.
Here, the width of the protrusion 14a is formed wider than the width of the annular groove 13a, and the annular groove 13a is expanded by fitting the protrusion 14a into the annular groove 13a so that the degree of sealing between the metal sleeve 7 and the drive cord 10 is increased. It will be further strengthened.

In FIG. 2, the multi-stage pole B shows a case of four stages, the uppermost stage pole 9 is followed by the second stage pole 1.
The fifth and third stage poles 16 and the fourth stage pole 17 are connected. Further, the top assembly A is fixed to the uppermost pole 9 by adhesion or the like, and the top assembly A is integrated with the uppermost pole 9 and enters the inside of the second-stage pole 15.

With this structure, when the multi-stage pole B is scaled down, the air in the pole is compressed and the insulator sleeve is passed through the inner and outer contact surfaces of the stopper 14 and the seal member 13. Although it tries to enter the inside of 6, it is strongly sealed by the seal member 13 and is prevented from entering, and the invasion of moisture is also prevented at the same time.

[0015]

As described above, in the vehicle corner pole according to the present invention, the sealing member is provided below the insulating sleeve incorporating the power feeding mechanism to prevent moisture from entering into the top assembly together with air. Therefore, it is possible to prevent the light emitting body and the power feeding mechanism from being corroded and the top lens from being adversely affected by the moisture.
