Description

[Detailed description of the invention] [Industrial application field] This invention is installed in a car so that the width of the car can be checked from the driver's seat. This invention relates to a multi-pole type automobile width indicator light that can be expanded and contracted.

[Prior Art] For beginners in car driving or those driving unfamiliar car models, the outside of the car body cannot be seen from the driver's seat, so when driving in and out of a garage or driving in a narrow alley, etc. It may be necessary to install a bar-shaped vehicle width indicator light at the front of the vehicle.

Such vehicle width indicator lights have already been put into practical use, such as those that are mounted on the bumper of a car in an upright position, and those that can be folded down when not in use so that they do not get in the way when being washed at a car wash. , or a double pole type that can be expanded and contracted by hand.

In addition, in order to be able to use it at night, some models are equipped with indicator lamps such as electric lights or light emitting diodes at the tip, but the vehicle width indicator light is a multi-pole type that can be extended and retracted, and it can be accessed from the driver's seat. If it were to be controlled remotely, it would be extremely difficult to transmit power to this indicator lamp, making the structure considerably more complicated, making it more likely that the power transmission system would fail, or making it difficult to replace the pole if it was damaged. This causes problems such as:

[Purpose of the invention] The purpose of the invention is to enable power to be transmitted to the indicator lamp by a relatively simple means in a multi-pole vehicle width indicator light equipped with an indicator lamp at the tip, and to control its expansion and contraction operation. To provide an easy-to-handle automobile width indicator light that can be automatically operated by remote control from the driver's seat.

[Summary of the invention] The gist of the invention to achieve the above objectives is as follows:
An annular storage chamber is provided around the rotating drum, which is driven by a motor that can rotate forward and backward through a clutch mechanism and a speed reduction mechanism, and is flexible and has a thin rod shape with a core wire inserted inside to supply power to the indicator lamp. A drive cord made of a synthetic resin is stored in a wound state in the annular storage chamber, and the drive cord is passed through a retractable multi-pole having the indicator lamp connected to the core wire at the tip thereof. The vehicle width indicator light is configured such that the multiple poles are expanded and contracted by extending and retracting the drive cord, the vehicle width indicator light having a mounting mechanism for the indicator lamp that does not transmit rotation of the tip of the multiple poles to the drive cord, As a power supply mechanism to the lamp, a power supply is connected to a rubbed conductive plate fixed to the inside of a drum cover made of an insulator that covers the rotating drum, and a slide provided on the rotating drum side is connected to the rubbed conductive plate. The vehicle width indicator light is characterized in that the sliding contact piece and the core wire are electrically connected by contacting the sliding contact piece with the core wire.

This drive cord 17 is made of a flexible thin rod-shaped synthetic resin, into which a core wire 18 for power supply is inserted, and the drive cord 17 is fed out from the cord entrance 19 by forward and reverse rotation of the rotating drum 14. Alternatively, it is wound up in the annular storage chamber 16 to drive a multiple pole 20 that can be expanded and contracted by stacking a plurality of poles.

A multi-pole 20 attached to an appropriate location such as the bumper of an automobile is connected to the cord entrance/exit 19 via a bent pipe 21, and the drive cord 17 is connected to the bent pipe 21.

As illustrated in FIGS. 5 and 6, an indicator lamp 51 (23 in FIG. 1) is provided at the upper end of the top pole 22 via a base metal 50, and power is supplied to the indicator lamp 51. A core wire 18 passing through the inside of the drive cord 17 is used as the electric wire. When replacing the indicator lamp 51, etc., when twisting the lamp cover 52 (25 in Fig. 1) screwed onto the base metal 50 and the indicator lamp 51, it is necessary to prevent rotational force from being transmitted to the internal drive cord 17. It is necessary to.

In the example shown in FIG. 5, a free slide portion 55 is formed between the outer surface of the drive cord 17 and the inner surface of the base metal 50 between the stopper ring 53 that stops the tip of the drive cord 17 and the auxiliary ring 54.

In the example shown in FIG. 6, the tip of the core wire 18 is joined to a stopper 60 attached to the end of the drive cord 17, the stopper 60 is received by an insulator 61 fitted inside the base metal 50, and the stopper 60 is received by the base metal 50. An example is shown in which a contact metal 63 for power supply is held down by an insulator 62 press-fitted into the inside of the cap 50, and a power supply spring 64 is interposed between the contact metal 63 and the stopper 60. In the case of FIG. 6 as well, when the lamp cover 52 is twisted, the stopper 60 sandwiched between the insulators 61 and 62 rotates to prevent rotational force from being transmitted to the drive cord 17. It's getting old.

It flows through the conductive plate 31 to be rubbed, the slide contact piece 34 rubbed thereon, the stopper 35, the conductive plate 36, and the stopper 37 to the core wire 18, and is supplied to the indicator lamp 51. However, the core wire 18 of the drive cord 17 housed on the rotating side and the power supply lead wire 3 on the drum cover 30 side, which is the fixed side,
In addition to this, various other modifications can be made to the power supply means for connecting 3. For example, a conductive ring as the conductive plate 31 to be rubbed is fixed to the inner surface of the side wall of the drum cover 30, and a slide contact piece 34 that rubs against this
may be attached to the outer peripheral surface of the rotating drum 14.

If the multi-pole 20 is damaged,
It would be necessary to replace the entire multiple pole 20 from the fixture 48. In order to make it easy to attach this device to, for example, an automobile bumper, a U-shaped elongated hole 70 is provided at the connection part of the bent pipe 21 to the cord inlet/outlet 19, as shown in FIG. It is desirable that the side screws 71 shown in the figure be fitted to create a structure in which the bent pipe 21 can swing depending on the surrounding situation.

FIG. 1 shows the state when the multi-pole 20 is completely retracted and not in use. In this case, the top of the lamp cover 25 at the tip is only slightly exposed from the car body 44. The multiple poles 20 do not get in the way at times.

To use this vehicle width indicator, press the switch from the driver's seat to display the indicator lamp 51 (2 in Fig. 1).
3) lights up, and the DC motor 2 is driven to drive the rotating drum 14 through the clutch mechanism and deceleration mechanism.
rotates, and the drive cord 17 housed in the annular storage chamber 16 is drawn out to push up and extend the multiple poles 20. Further, when the DC motor 2 is reversed, the drive cord 17 is wound up in the annular storage chamber 16, and the multiple poles 20 are contracted and stored in the state shown in FIG.

The indicator lamp 51 may be turned on, for example, in conjunction with the lighting of a small lamp of a car, but it must be turned off when the multi-pole 20 is contracted. Therefore, drive code 17
A conductive stopper 37 attached to one end of the
moves as the drive cord 17 is extended and retracted, comes into contact with the conductive plate 36 when extended, and leaves the conductive plate 36 when retracted. By doing so, the indicator lamp 5
1 will definitely be turned off when the drive code 17 is retracted.

[Effects of the invention] As explained above, although the vehicle width indicator lamp according to the invention is a flexible multi-pole type, it is possible to reliably transmit power to the indicator lamp at the tip. Moreover, the expansion and contraction operations can be performed automatically by remote control from the driver's seat. Furthermore, when the multi-pole supporting the indicator lamp is damaged, the entire multi-pole section can be easily replaced. Furthermore, when replacing the indicator lamp, even if the lamp cover is twisted, the rotational force is not applied to the drive cord, so the drive cord and the core wire inside it can be safely protected.
