Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a wire type window regulator that drives a window glass of an automobile to open and close by transferring a wire.

[Prior art and its problems]

Generally, a wire type window regulator is constructed as shown in FIG. In the figure, reference numeral 31 is a guide rail, which is attached in the vertical direction of the automobile door 40. The guide rail 31 has wire guides 32 and 33 at its upper and lower ends and slidably supports a carrier plate 34. Further, the base plate 2 is attached at a position separated from the guide rail 31, and the rotary drum 11 which is rotated by the motor 12 is arranged on the base plate 2. Then, the wire 35 is wound around the rotary drum 11, and both ends of the wire 35 are bridged over the wire guides 32 and 33 and are coupled to the carrier plate 34.

By the way, the wire 3 between the base plate 2 and the wire guide 32, and between the base plate 2 and the wire guide 33.
5 passes through outer tubes 36, 37 having a certain degree of rigidity capable of maintaining an assembled state, and both ends of each outer tube 36, 37 are fixed to the upper and lower ends of the base plate 2 and the guide rail 31 by tube holders 52, 53. , 54, 55.

Conventionally, a tube holder 5 fixed to the base plate 2
Reference numerals 2 and 53 were made of synthetic resin in the shape shown in FIG. 7, and one end thereof was fixed to the end edge portion of the base plate 2 in a cantilever manner as shown in FIG. For this reason, the wire 35, which is slackened when the window regulator is fully closed and fully opened, and the outer tubes 36 and 37 are tensioned. There is a problem that the stress is concentrated and the tube holders 52 and 53 are cracked. Further, since the tips of the tube holders 52 and 53 project from the base plate 2, there is also a problem that an external impact is easily applied.

[Means for solving problems]

The present invention is intended to provide a wire type window regulator which solves the problems existing in the above-mentioned conventional techniques, and is achieved by a window regulator 1 shown below.

That is, according to the present invention, a wire is wound around a rotary drum arranged on a base plate, and both ends of the wire are connected to a carrier plate supporting a window glass through a tube holder fixed to the base plate and an outer tube held by the tube holder. In the wire type window regulator 1, the tube holder 7 (same for the 8 side) is formed into a tubular shape having a large diameter flange portion 7b at one end and a clasp attachment portion 7c at the other end, and a base plate. 2 is provided with a pair of support portions 3i, 3o each having a support hole 5i, 5o formed by bending a part at a right angle and facing each other in the wire direction, and inserting the tube holder 7 into the support hole 5i, 5o. It is characterized in that the clasp 13 is attached and fixed to the clasp attachment portion 7c.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view showing a main part of a wire type window regulator according to the present invention, FIG. 2 is a partial sectional view taken along the line AA in FIG. 1, and FIG. 3 is a vertical sectional view taken along a circle B in FIG. Figures and 4 are the same B
It is an exploded perspective view showing a part of part.

First, a main part configuration of the window regulator 1 according to the present invention will be described.

Reference numeral 2 is a base plate, and a rotatable drum 11 is provided on the base plate 2. A motor 12 is arranged on the base plate 2, and the rotation output of the motor 12 is transmitted to the rotary drum 1 via a speed reduction mechanism and a buffer mechanism.
1 is transmitted.

On the other hand, at the upper edge and the lower edge of the base plate 2, supporting portions 3o and 4o bent at right angles are formed.
Support holes 5o and 6o having split grooves (see FIG. 4S) in o
To form. On the other hand, the second support portions 3i, 4i facing the support portions 3o, 4o are provided by bending at right angles on the base plate surface located inside the support portions 3o, 4o.
In this case, each of the support portions 3i and 4i may be formed, for example, in a U-shaped notch on the surface of the base plate 2 and the piece cut out inward may be bent. Support holes 5i and 6i having split grooves S are also formed in the support portions 3i and 4i (see FIG. 4). Therefore, the straight line connecting the centers of the support holes 5o and 5i becomes the tangent line of the rotating drum 11, and similarly the support holes 6o and 6i are formed.
A straight line connecting the centers of the two also becomes a tangent to the rotary drum 11.

The tube holders 7 and 8 are fixed to the support portions 3o and 3i and the support portions 4o and 4i, respectively. Tube holder 7
Is integrally molded with a synthetic resin into a cylindrical shape, and is provided with a holder main body 7a to be inserted into the support hole 5o, a flange portion 7b having a diameter larger than that of the main body 7a is provided at one end, and the main body 7a is provided at the other end. A clasp attaching portion 7c having a smaller diameter than that of the clasp attaching portion 7c to be inserted into the support hole 5i is provided. A ring groove 14 for mounting a clasp (for example, E ring) 13 is formed on the outer periphery of the clasp attachment portion 7c. Further, a through hole 7k is provided inside the tube holder 7. The vicinity of the attachment portion 7c is formed to have a relatively small diameter through a step. The coil spring 15 is inserted into the through hole 7k, and the outer tube 36 is further inserted through the spring retainer 16. The other tube holder 8 is exactly the same.

The other parts of the window regulator 1 are the fifth
The configuration is the same as that already described with reference to the drawing.

Therefore, the support portions 3i, 3o, 4i, and 4o can be easily integrally formed at the same time when the base plate 2 is formed (press forming, etc.), and the support holes 5o and 5i of the support portions 3o and 3i are formed.
If the tube holder 5 is inserted into i and the stopper 13 is attached to the ring groove 14 in the completely inserted state, it can be easily assembled and fixed.

Further, according to the configuration of the embodiment, the tube holder is supported on both sides of the tube holder, so that the tube holder can have sufficient strength to withstand concentrated stress due to tension of the wire. Moreover, since the tube holder is fixed within the surface of the base plate, it does not needlessly project to the outside and is also protected externally.

Although the embodiments have been described in detail above, the present invention is not limited to such embodiments. For example, the case where a hole is formed in the support part and the support part is inserted is shown.
A notch having a shape may be provided, and the notch may be inserted from the direction perpendicular to the axis. In addition, the detailed configuration, shape, quantity and the like can be arbitrarily changed and implemented without departing from the scope of the present invention.

[Effect of device]

As described above, the wire type window regulator according to the present invention is provided with a tubular tube holder having a large-diameter collar portion at one end and a clasp attachment portion at the other end, and a part of the base plate. Providing a support part that is bent at a right angle and has a pair of support holes facing each other in the wire direction, inserts the tube holder into each support hole, and mounts a clasp on the clasp attachment part to fix it. Therefore, the following remarkable effects are obtained.

The mechanical strength of the tube holder can be significantly increased, and cracking does not occur due to stress concentration at the time of fully closing or fully opening, and thus the durability can be dramatically improved.

Assembly can be performed with one touch, is extremely simple, and since the tube holder can be securely and firmly fixed, further improvement in durability and reliability can be achieved.
