Abstract

(57) [Summary] [Purpose] To prevent moisture from entering the top assembly of the corner pole. [Structure] A seal member 13 is arranged between a metal sleeve 7 and a drive cord 10 of a top assembly A, and a stopper 14 having a protrusion 14a is attached to a lower portion thereof to attach the seal member 13.
4a is inserted into the annular groove 13a provided in the seal member 13, and the seal member 13 is expanded. When the multi-stage pole is scaled down, the air containing water therein is compressed and tends to be jetted from the inner and outer circumferences of the stopper 14 and the seal member 13, but since it is sealed by the seal member 13,
Water is prevented from entering the top assembly A.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a retractable vehicle corner pole that is attached to a corner portion of a vehicle so that a driver of the vehicle can check the vehicle width.

[0002]

[Prior Art]

 Conventionally, this type of corner pole for automobiles uses an expandable telescopic pole with an emitter such as a light emitting diode attached to the upper end, and by pushing out the drive cord that passes through the interior of the multistage pole, the entire pole Is extended and the drive cord is pulled in the opposite direction to reduce the scale. The pole itself, which consists of an electric wire and a conductive metal tube that runs inside the drive cord, is used as a means of supplying power to the light emitter.

A top assembly including a light emitting body and a top lens covering the light emitting body is attached to an uppermost pole, and inside the pole, a power supply for electrically connecting the electric wire passing through the inside of the drive cord and the light emitting body. The mechanism is incorporated.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional example, 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. Or give.

For this reason, in the past, measures using grease or the like have been taken, but sufficient effects have not been obtained. An object of the present invention is to solve the above-mentioned 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]

[Means for Solving the Problems]

 A corner pole for an automobile according to the present invention for achieving the above-mentioned object comprises an expandable telescopic multi-stage pole and a top assembly including a light emitting body attached to the upper end of the multi-stage pole. Is a corner pole for automobiles that has a built-in drive cord that inserts an electric wire for driving the multi-stage pole, and has a substantially cylindrical shape made of an elastic material between the metal sleeve provided around the top assembly and the drive cord. The seal member is arranged.

[0007]

[Action]

 In the vehicle corner pole having the above structure, the drive cord and the metal sleeve holding the top assembly are sealed with a seal member to prevent moisture and the like from entering the top assembly.

[0008]

【Example】

 The present invention will be described in detail with reference to the illustrated embodiment.

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 detached from the multistage pole B. The top assembly A is a light emitting body 1 such as a light emitting diode, an inner lens 2 made of a transparent synthetic resin which is disposed above the light emitting body 1 and has a plurality of cuts 2a formed on the outer periphery thereof, and a transparent synthetic body which surrounds the light emitting body 1 and the outer side of the inner lens 2. Top lens 3 made of resin, lens cap 4 screwed into the upper end thereof, earth metal 5 to which one terminal 1a of light emitting body 1 is connected, insulator sleeve 6 located under this earth metal 5, insulator sleeve 6 6 and the top lens 3 are provided with a metal sleeve 7 which is provided around the lower part of the top lens 3 and connects them, and a conductive spring 8 which is installed inside the insulator sleeve 6 and presses the ground metal 5.

The terminal 1 b on the other side of the light emitting body 1 is wound around a half groove along the concave groove on the outer periphery 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, but as shown in the figure, from the outside of the metal sleeve 7, P1, It is easy to punch and stop several points like 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. The tip of the electric wire 12 passing through the inside of the drive cord 10 is electrically connected to the cord stopper metal 11, and is connected to the light emitting body 1 via the conductive spring 8 and the earth metal 5.

In addition, a substantially cylindrical seal member 13 made of an elastic material having a circumferential annular groove 13 a on the lower surface of the insulating sleeve 6 seals between the metal sleeve 7 and the drive cord 10. And is fixed by a stopper 14 having a circumferential protrusion 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 sealing degree between the metal sleeve 7 and the drive cord 10 is increased. It will be further strengthened.

Note that, in FIG. 2, the multi-stage pole B shows a case of four stages, and the second stage pole 15, the third stage pole 16, and the fourth stage pole 17 are connected following the uppermost stage pole 9. 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 configuration, 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 intrusion of moisture is also prevented at the same time.

[0015]

[Effect of the device]

 As described above, in the vehicle corner pole according to the present invention, the sealing member is provided below the insulating sleeve in which the power feeding mechanism is incorporated, and moisture is prevented from entering into the top assembly together with the air, and the light is emitted by the moisture. The body and power supply mechanism will not be corroded and the top lens will not be adversely affected.
