Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a defogger glass for anti-fogging and defrosting that rises and falls on a rear window or side window of a vehicle. More specifically, the present invention relates to a wiring structure of a power supply wire that connects to a defogger printed wire attached to a window glass or a defogger tungsten wire embedded in an intermediate film portion of a laminated glass to supply power.

[Prior Art] In order to prevent damage to the defogger print line when the window glass is raised and lowered, the present applicant has developed an automobile door that automatically separates the lip of the weather strip from the glass surface when the window glass is raised and lowered. (Japanese Patent Application Laid-open No. 58-128921).

[Problems to be Solved by the Invention] However, even with the above automobile door, the power supply position of the defogger print wire on the window glass surface changes greatly between when the window glass is fully closed and when it is fully opened. In this case, the power supply wire had to be allowed to slacken in a narrow space on the inner panel side of the door that accommodates the window glass either when it is fully closed or fully opened.

For this reason, when the window glass is raised and lowered, the power supply wire tends to come into contact with the window regulator mechanism for raising and lowering the window glass, resulting in wire breakage and damage to the insulation coating. Furthermore, when the door was closed, the power supply wire was struck against the inner panel, which could lead to poor connection at the connection section.

The purpose of the present invention is to improve the above points,
It is an object of the present invention to provide a wiring structure for a power supply wire of a heating wire for a defogger that does not cause disconnection, damage to insulation coating, or poor connection even when a window glass is raised and lowered or a door is opened and closed.

[Means for Solving the Problems] The present invention provides a deformable wire guide that is attached to the window glass, and is provided with a deformable wire guide between the lower end of the window glass that moves up and down and the wind regulator arm that moves up and down the window glass. The present invention is characterized in that the power supply wire of the heating wire for the defogger is deformed in accordance with the deformation of the wire guide so that it does not hang down inside the vehicle body.

[Example] Next, an example of the present invention will be described in detail based on the drawings.

As shown in the first embodiment shown in FIG. 1, an X-arm type window regulator 12 is provided on the inner panel within the side door body 10. Main arm 13 and sub arm 1 of this regulator 12
One end of each of the sub-arms 14 is connected to the glass bottom channel 15, and one end of the sub-arm 14 is connected to the guide channel 17.
They are each slidably provided. A fan-shaped gear 18 is fixed to the other end of this main arm 13,
It meshes with a pinion 19 that is rotated by a regulator handle (not shown). glass bottom channel 1
A window glass 20 is mounted on top of the window 5. On the inner surface of this window glass 20, a horizontally linear heat ray print 21 for a defogger is attached.

The characteristic configuration of this embodiment is that a bracket 22 is attached to the lower left end of the window glass 20, and a telescopic wire guide 24 is provided between the bracket 22 and the sub-arm 14, and the hot wire print 2
A power supply wire 25 that connects to the wire guide 1 and supplies power passes through the wire guide 24 and connects to the wire guide 24.
It is fixed at both ends.

That is, as shown in FIG. 2, the wire guide 24 includes an outer cylindrical body 26 and an inner cylindrical body 27 loosely inserted into the outer cylindrical body.
and a coil spring 28 installed inside both cylindrical bodies. One end 26a of this outer cylindrical body 26 is pivotally attached to the bracket 22. Also, the base end 2 of the inner cylinder body 27
7a is pivotally connected to the sub-arm 14. Outer cylinder body 26
and the length of the inner cylindrical body 27 when the window glass 20 is in the half-opened state as shown in FIG.
As shown in the figure, the bracket 22 and sub-arm 14 when the window glass 20 is fully closed or fully opened.
Selected according to the interval. The wire 25
As shown in the figure, when the inner and outer cylinders 27, 26 reach their maximum length, the base end 27a and one end 2
6a, each is fixed with screws 29 and 30, attached to the sub-arm 14, and connected to a power supply system (not shown).

In such a configuration, when the pinion 19 is rotated by a regulator handle (not shown), the fan-shaped gear 18 is rotated, and the window glass 20 is raised and lowered by sliding of the arms 13 and 14. The two-dot chain line in FIG. 1 shows the state when the window glass 20 is fully opened. Here, the wire guide 24 freely expands and contracts due to the elastic force of the coil spring 28, and as shown in FIG. Loosen the wire 25. Thereby, the wire 25 does not hang down inside the side door body 10 due to the rise and fall of the window glass 20.

4 to 6 show a second embodiment of the present invention. The characteristic structure of the second embodiment is that the wire guide 24 has a single tubular body 32 and a screw 29 that passes through this tubular body 32 and has one end attached to a proximal end 32a of this tubular body.
and a coil spring 28 whose other end is pivotally connected to the bracket 22, and the wire 25
passes through this tubular body 32 and is held along the coil spring 28 by a tape 33.
As shown in FIG. 6, the coil spring 28 is formed in a straight line on the side where the bracket 22 is attached. The coil spring 28 is attached by forming its tip 28a into a C-shape, inserting it into the slit 22a of the bracket 22, aligning it with the hole 22b, and then inserting the pin 34 into the hole 22b. Further, the wire 25 is fixed by screws 29 and tape 33 in a state where the coil spring 28 is at its maximum extension when the window glass 20 is partially closed.

With such a configuration, when the window glass 20 is raised or lowered, the coil spring 28 shown in FIG. 6 contracts,
In response to this contraction, the wire 25 loosens within the tube body 32. Thereby, the wire 25 does not hang down inside the side door body 10 due to the rise and fall of the window glass 20.

7 to 9 show a third embodiment of the present invention. The characteristic structure of the third embodiment is that the wire guide 24 is made of a highly elastic steel wire 36, one end 36a of this steel wire 36 is pivotally connected to the sub-arm 14, and the other end 36b is connected to the bracket 2.

It is attached by 3. The steel wire 36 is attached to the other end 3 in the same way as the coil spring in the previous embodiment.
6b is formed into a C-shape, and is inserted into the slit 22a of the bracket 22, aligned with the hole 22b, and then the pin 34 is inserted into the hole 22b (FIG. 8). Further, one end 36a of the steel wire 36 is inserted into a hole in the arm 14, and is held by a holding plate 37 to prevent it from rising (FIG. 9). This steel wire 36 has a length corresponding to the maximum distance between the bracket 22 and the hole in the arm 14 when the window glass 20 is half opened.

With such a configuration, when the window glass 20 is moved up and down, the steel wire 36 is extended, and the wire is bent in accordance with this extension. Thereby, the wire 25 does not hang down inside the side door body 10 due to the rise and fall of the window glass 20.

In the above example, the window glass of the side door of the vehicle was shown as an example, but the rising and falling window glass of the rear door that can be opened and closed is not limited to door glass, but also the rising and falling window glass of the rear quarter window, etc. Of course, it can also be applied to

Further, although an example of hot wire printing has been shown as a heating wire for a defogger, a tungsten wire embedded in the interlayer film of a laminated glass may also be used, and the wire is not limited to a heating wire but can also be used as an antenna wire for a vehicle communication device.

[Effects of the Invention] As described above, according to the present invention, a deformable wire guide is provided between the lower end of the window glass that moves up and down and the wind regulator arm that moves up and down the window glass, and By configuring the power supply wire of the attached defogger heating wire to deform in accordance with the deformation of this wire guide, the wire will not be damaged inside the vehicle even if the window glass rises or the door is forcefully closed. It is possible to electrically reliably supply power to the heating wire without any trouble.
