BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire type window regulator device.

[0002]

2. Description of the Related Art Conventionally, as a window regulator device for raising and lowering a window panel of an automobile, for example, Japanese Society of Automotive Engineers, New Edition of Automobile Engineering Handbook, No. 6
As shown in the knitting and vehicle bodies I-14 and 15, there is known a wire type type in which the operation is controlled by a wire.

As shown in FIG. 6, a wire type window regulator device is provided on a base plate 101 which can be mounted on a vehicle body side, and has a driving portion 105 to which a drum 103 is fixed, and a guide rail having upper and lower guide portions 107. A member 109, a pair of upper and lower flexible outer tubes 111 each having one end mounted on the base plate 101 and the other end mounted on the upper and lower guides 107 on the guide rail member 109 side, and the drum 103 And a carrier plate 115 connected to the wire 113 and moved up and down along the guide rail member 109 by being pulled by the wire 113. The carrier plate 115 has a window panel 118 And has a mounted structure.

[0004]

As described above, the wire 113 for pulling and controlling the carrier plate 115 is fed out of the drum 103, and then passes through the outer tube 111 and is routed along the guide rail member 109. It has become.

In this case, since the wire 113 and the outer tube 111 are flexible, even if a slight deviation occurs in the mounting position of the driving portion 105, the deviation is absorbed and the operation is not adversely affected. , Drive unit 10 according to the vehicle type
When the mounting position of the fifth unit 5 is moved closer to the guide rail member 109 or is mounted at a position distant from the guide rail member 109, the driving unit 1
The positional relationship between the wire 05 and the guide rail member 109 is greatly collapsed, which causes a problem that the wiring state of the wire 113 is deteriorated.

At this time, the terminal portion 1 of the outer tube 111
17 has an impossible shape with respect to the mounting portion 119 of the base plate 101, so that the sliding resistance between the wire 113 and the outer tube 111 is increased, and the durable life of the wire is significantly shortened. Problems such as heavy steering operation occur.

Accordingly, an object of the present invention is to provide a wire type window regulator device capable of suppressing the sliding resistance of a wire without being affected by the mounting position of a drive unit.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a drive unit having a base plate which can be mounted on a vehicle body and a forward / reversely rotating drum provided on a base plate, and a guide unit provided above and below. A guide rail member, one end portion is attached to the base plate, and the other end portion is a pair of upper and lower flexible outer tubes attached to upper and lower guide portions on the guide rail member side, respectively. A wire that is routed along the guide rail member through the outer tube, and a carrier plate that is connected to the wire and that moves up and down along the guide rail member by traction by the wire; A mounting portion that forms a mounting region along an arc line having a center substantially at the dispensing point is provided, and the terminal portion of the outer tube is attached to the mounting portion. It is detachably mounted in an appropriate position.

[0009]

In this wire type window regulator device, the end portion of the outer tube is mounted at an optimum position with respect to the mounting portion of the base plate in accordance with the mounting position of the driving portion, so that a reasonable wire is provided. Can be routed. Therefore, a large sliding resistance does not act during the operation of the wire, and a smooth operating state can be obtained.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a wire-type window regulator device which is assembled in an inner space of a door (not shown).

The window regulator device 1 includes a guide rail member 3, a carrier plate 5 that can move up and down along the guide rail member 3, a wire 7 that moves the carrier plate 5 up and down, and a driving unit that controls the pulling of the wire 7. 9
It is composed of

The guide rail member 3 includes right and left rail portions 1 which rise from both sides of the rail body and are formed in a curled shape.
The upper and lower ends of the door are provided with guide portions 13 and 13 for guiding the wire 7, respectively, and are provided on the inner panel (not shown) of the door via a bracket 14. To be mounted.

The carrier plate 5 includes left and right mounting portions 15 to which the window panel 20 is mounted, and a wire locking and holding portion 17 provided at a substantially central portion to which the wires 7 are connected.
And is slidably attached to the rail portion 11 of the guide rail member 3.

The drive section 9 is provided with a drive shaft 23 and a drum 25 mounted on the drive shaft 23 on a base plate 21 having a mounting hole 19 for mounting to an inner panel (not shown) of the door. . The carrier plate 5 is provided on the drum 25 along the guide rail member 3.
Is wound around the wire 7. On the other hand, the drive shaft 23 is supplied with forward rotation or reverse rotation by a manual handle or a drive motor, and when one of the wires 7 is fed when the drum 25 rotates forward or backward. With the other rolled in, the traction control of the carrier plate 5 upward or downward can be performed.

The base plate 21 is provided with a first mounting portion 27 and a second mounting portion 27, respectively.
One end 31 of a flexible outer tube 29 is attached to each mounting portion 27. The other end portion 33 of the outer tube 29 is fitted and fixed to the upper and lower guide portions 13 on the guide rail member 3 side. Each mounting part 27
One end 31 of outer tube 29 attached to
Are a pair of opposed flange portions 31a, 31a, and an engagement groove 31b between the flange portions 31a and 31a.
And a shape consisting of

The first and second mounting portions 27 are provided on the drum 2
5 is provided along the arc line w from substantially the center of the feeding point p, and a specific example is shown in FIGS.

That is, the mounting portion 27 is formed in a shape of an elongated long hole 35 along a circular arc on a rising wall 37 that rises from the base plate 21, and the area of the long hole 35 is an attachment area. I have. The diameter of the elongated hole 35 is smaller than the flange portion 31a of the one end portion 31 of the outer tube 29, and slightly larger than the engagement groove 31b, so that the engagement groove 31b can be fitted to the elongated hole 35. It has become. Further, at one end of the elongated hole 35, an insertion hole 37 having a diameter larger than the diameter of the flange portion 31a of the terminal portion 31 of the outer tube 29 is continuously provided. 31 can be inserted. The upper and lower edges of the elongated hole 35 serving as the mounting portion 27 are provided with convex portions 39 for positioning the outer tube terminal portion, and the insertion hole 37 provided on one side of the elongated hole 35 has a terminal. Part 3
An elastically deformable blind plug 41 for preventing the 1 from coming off is detachably fitted.

In the window regulator device 1 configured as described above, for example, when the mounting position of the drive unit 9 is changed according to the type of vehicle, the terminal portion 31 of the outer tube 29 is connected as shown by a chain line in FIG. Each mounting part 27, 27
By selecting the mounting position and mounting the wire 3, it is possible to perform the reasonable routing of the wire 3.

Therefore, if the drum 25 is rotated forward or backward to control the pulling of the wire 7, the carrier plate 5 moves up and down along the guide rail member 3. In this case, no excessive sliding resistance acts on the wire 7, and a smooth operating state can be obtained.

The mounting portion 27 does not necessarily need to have a long hole shape. For example, as shown in FIG. 6, the mounting portion 27 may be formed in a notched groove shape having an open upper portion, and a plurality of notched grooves may be provided.

[0022]

As described above, according to the wire type window regulator device of the present invention, the sliding resistance of the wire can be reduced without being affected by the mounting position of the drive unit. As a result, the durability life of the wire is greatly extended, and the operability can be improved.
