Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge which enables wiring in a hinged door or the like.

[0002]

2. Description of the Related Art For example, in a van type automobile 1 as shown in FIG. 3, electrical components such as a high-mount stop lamp for preventing a rear-end collision and a rear wiper are mounted on a rear door 2.

In this case, some electric wiring is required between the rear door 2 connected with the hinge 3 and the vehicle body 4.

Conventionally, the electric wiring is provided with an exposed wiring inside a door portion hinged, or a connector is arranged on each of the door portion and the vehicle body side, and the wiring is mutually connected by the connector simultaneously with closing the door. Means such as coupling to enable power supply have been employed.

[0005]

However, according to the former means in the prior art, troubles are caused by the opening / closing operation of a door that rotates approximately 270 degrees or damage caused by contact during cargo handling performed in the open state. There was a problem that occurrence was unavoidable.

According to the latter means, the connection and disconnection of the wiring are performed intermittently with the opening and closing of the door.
Problems such as generation of inrush current, leakage, and short circuit have occurred.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a door wiring hinge for performing safe and reliable wiring even in a door part where opening and closing operations are frequently performed.

[0008]

According to the present invention, a hinge pin formed by two hollow pipes has one end fixed to a post and the other end fixed to a post.
Penetrate the upper and lower post hinge pieces, and
The door-side hinge piece is inserted into the cylinder part of the door-side hinge piece disposed between the post-side hinge pieces , facing each other via an appropriate gap, and communicates with the gap of the door- side hinge piece. A door-side wiring lead-out passage is provided.

[0009]

In the present invention, an electric wire is inserted through the hinge pin formed by two hollow pipes. Inserted through said electric wire, the gap provided between the hinge pin in the door side hinge piece, de communicating with the gap portion
It is wired to the door via the a-side wiring lead-out passage.

Therefore, even when the hinge piece is rotated about the hinge pin, no excessive load is applied to the wiring.

Therefore, even when the door-side hinge piece is rotated about the hinge pin, no excessive load is applied to the wiring.

FIG. 1 is a perspective view showing an embodiment of the present invention.

In FIG. 1, reference numeral 2 denotes a rear door, and reference numeral 5 denotes a rear post of the vehicle body.

The door wiring hinge 6 includes a door hinge piece 7 fixed to the rear door 2, a rear post hinge piece 8 fixed to the rear post 5, and a door hinge piece 7 connected to the rear post side. And a hinge pin 9 pivotally attached to the hinge piece 8.

The hinge pin 9 is composed of two hollow pipes, one ends of which are fixed to the rear post 5, respectively. The other ends 11, 11 of the two hinges 9, 9 are respectively connected to the rear posts arranged vertically.
Through the hinge pieces 8, 8, and further into the rear post side heat sink.
Door-side hinge piece 7 disposed between the flange pieces 8, 8
Are inserted into each other from above and below via an appropriate gap S.

As shown in FIG. 2, which is a cross-sectional plan view at the center in FIG. 1, a lateral hole communicating with the gap S provided in the cylindrical portion 12 is formed in the cylindrical portion 12 of the door side hinge piece 7. 15 are drilled. The lateral hole 15 is a door-side wiring lead-out passage 15 for passing an electric wire to the door side . At the end of the door-side wiring lead-out passage 15, a wiring cover 17 for covering the lead-out electric wire is provided with an appropriate length.

In the drawings, reference numerals 18 and 19 denote connectors, respectively, and reference numeral 20 denotes the rear post-side hinge piece 8.
And fixing flanges for fixing the hinge pins 9, 9 inserted into the pin insertion holes 13, 13, respectively.

In the hinge of the present invention configured as described above, the wiring from the rear post 5 side is spirally inserted into the hinge pins 9 and 9, and the wiring from the gap S to the door side wiring. It is guided to the rear door 2 side through the wiring cover 17 through the lead-out passage 15. Therefore,
Even if the rear door 2 is fully opened to 270 degrees, no extra burden is applied to the wiring.

Since the upper and lower hinge pins 9, 9 are formed by hollow pipes as described above, a large number of electric wires can be passed therethrough, and more power can be supplied by one hinge.

[0020]

According to the present invention, since there is almost no load on the wiring due to opening and closing of the door, there is an effect that the wiring of the door portion hinged is performed safely and reliably.
