Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a regulator for raising and lowering a window glass of a vehicle, and more particularly to a drive wire holding mechanism for the regulator.

[0002]

2. Description of the Related Art In a conventional vehicle, an actual flat tire 2-39 is used.
As illustrated in Japanese Patent No. 088, one cable is position-regulated by a cable holder attached to a guide rail of a power window regulator, and upper and lower cables are connected to each other at an intermediate portion thereof. , When the window glass starts to descend due to the drive of the motor and the restraint around the window glass is released, the cable extending between the winding drum and the guide rail swings significantly. The intermediate portion of the cable interferes with the portion of, and there is a problem that abnormal noise is generated or abrasion is caused.

In order to suppress the above vibration of the cable, it may be possible to hold the middle portion of the cable on the door panel with a clip. In this case, the clip is always inserted accurately into the through hole on the door panel side. As such, the power window regulator will be assembled with the cable loosely inserted into the clip. Therefore, when the power window regulator is attached to the vehicle door panel, the clip descends along the cable due to its own weight and is located near the winding drum. Since it is necessary to lift the clip along the cable to the position of the door panel through hole while groping inside, the workability of installing the power window regulator is significantly deteriorated.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to suppress vibration of a drive wire in a window glass regulator of a vehicle, and at the same time, to easily attach the window glass regulator to the vehicle.

[0005]

In order to achieve this object, a window glass regulator according to the present invention comprises:
A drive wire, a winding drum of the drive wire, a support member connected to the drive wire and connected to the window glass side, a guide member for guiding the support member in the up-and-down direction of the window glass, and a vehicle body side. It has a clip that is frictionally engaged with the outer peripheral surface of the drive wire that is attached and extends between the winding drum and the guide member, and that is relatively displaceable in the longitudinal direction of the drive wire.

[0006]

Therefore, when the window glass regulator is mounted on the vehicle, the clip that frictionally engages with the outer peripheral surface of the drive wire extending between the winding drum and the guide member vibrates the drive wire as the window glass moves up and down. If the clip is frictionally engaged at a proper position of the drive wire extending between the winding drum and the guide member when the window glass regulator is assembled, the window glass regulator can be mounted on the vehicle. At that time, it is not necessary to manually operate the clip, and it is possible to easily prevent the workability from being impaired, and the initial vibration of the drive wire after the window glass regulator is attached causes the clip that is frictionally engaged with the drive wire to be driven. Appropriate position by appropriately displacing in the longitudinal direction of the wire Automatically adjusted, it is possible to effectively exhibit the vibration suppressing action of the drive wire.

[0007]

Embodiments of the present invention shown in the drawings will be described below.
The same parts will be described with the same reference numerals. In FIG. 1, a power window glass regulator 1 includes a motor 2, a winding drum 3 that is connected to the motor 2 and is rotated by driving the motor 2, and a drive wire 4 that is biased by the rotation of the winding drum 3. , A guide rail 5 and a carrier plate 6 that holds the guide rail 5 and is guided in the longitudinal direction of the guide rail 5,
Is composed of an outer cable 7 and 8 extending between the winding drum 3 and the guide rail 5 and an inner cable 9 inserted through the outer cable 7 and 8. The inner cable 9 is wound around the winding drum 3 and It is hung on a pulley 10 pivotally supported on the upper end of the guide rail 5, extends into the guide rail 5, and is connected to a carrier plate 6. In addition, at the almost middle position of the outer cable 7,
A clip 11 integrally formed of nylon, polyacetal, or the like is attached to the outer peripheral surface of the outer cable 7.

The clip 11 has a thin-walled portion 12 at the top thereof, as shown in the enlarged view of FIG.
3 and left and right arms 14, 15 and a skirt portion 16 and an approximately semi-cylindrical overlapping portion 17, 18 formed at one end of each arm 14, 15, respectively.
Ribs 19 are formed on the outer sides of the respective arms, a notch 20 is provided on the upper edge of the arm 14, and a hook 23 including an arm 21 and an inclined head 22 is provided on the upper edge of the arm 15. ing. Further, the overlapping portion 17 is formed with an upper locking portion 24 and a downward recess 25 that are elastically bendable up and down, while the overlapping portion 18 is a lower locking portion that is elastically bendable up and down. 26 and an upward protrusion 27 are formed.

Therefore, in the state where the drive wire 4 is arranged in the wire holding portion 13, the bending elasticity given to the wire holding portion 13 by the thin portion 12 is utilized to make the clip 11
When the left and right arms 14 and 15 that have expanded are brought close to each other, when the inclined head 22 of the hook 23 comes into contact with the end edge of the notch 20, the arm 21 elastically bends in the substantially front-back direction of FIG. While the inclined head 22 passes through the notch 20 and the arm 21 fits into the notch 20, the lower end edge of the overlapping portion 17 is moved by the relative elastic deformation of the tips of the arms 14 and 15 in the vertical direction in FIG. The protrusion 27 of the overlapping portion 18 is displaced along the inclined surface, and when the protrusion 27 gets over the protrusion 27, the protrusion 27 is fitted into the recess 25 in the vertical direction of FIG.
By overlapping 7 and 18 to form a substantially cylindrical shape,
Assembled as shown in FIG. 3, the drive wire 4 is held in the wire holding portion 13.

At this time, as well shown in FIG. 4, due to the elasticity of the outer peripheral surface of the outer cable 7 and the elasticity of the inner surface of the wire holding portion 13 due to the thin portion 12, the drive wire 4 is placed inside the wire holding portion 13. Since the clip 11 is elastically sandwiched, the clip 11 is frictionally engaged with the drive wire 4 with an appropriate strength, and the mounting position of the clip 11 is not easily displaced due to transportation of the power window glass regulator 1 or the like. Although a gap 28 is formed between both side surfaces of the drive wire 4 and the inner surface of the wire holding portion 13,
This void may not be generated.

When the power window glass regulator 1 assembled as described above is mounted in the door panel of a vehicle, the motor 2 and the winding drum 3 are integrated.
After fixing the guide rail 5 and the guide rail 5 to predetermined positions on the inner surface of the door panel with screws or the like, the holder attached to the lower end of the door window glass and the carrier plate 6 are connected with screws or the like. As shown in FIG. 5, a through hole 3 formed in the door panel 30 corresponding to a substantially intermediate position of the outer cable 7.
When the overlapping overlapping portions 17 and 18 of the clip 11 are pushed into the clip 1, the upper engaging portion 24 and the lower engaging portion 26 of the overlapping portions 17 and 18 can be elastically bent up and down. The clip 11 is attached to the door panel 30 by passing through the through hole 31, and the edges of the left and right skirt portions 16 contact the door panel 30.
It is possible to prevent the falling of.

When the power window glass regulator 1 is mounted in the door panel of the vehicle as described above, the winding drum 3 is rotated by the drive of the motor 2 and the inner cable 9 of the drive wire 4 is pulled and the inner cable 9 is pulled.
By raising and lowering the carrier plate 6 connected to the guide rail 5 along the guide rail 5, the door window glass can be opened and closed up and down as in the case of the conventional device, but the drive wire 4 is located at a substantially intermediate position of the outer cable 7. Since it is held by the clip 11 in the above, the swing of the drive wire 4 accompanying the opening and closing of the door window glass is effectively suppressed,
Therefore, it is possible to reliably prevent the drive wire 4 from interfering with the door window glass and causing abnormal noise or abrasion.

When the power window glass regulator 1 is assembled, since the clip 11 is engaged with the drive wire 4 at a substantially intermediate position of the outer cable 7, when the power window glass regulator 1 is mounted in the vehicle door panel. Has no need to search for the clip 11 in a narrow door panel, and the clip 11 can be fixed to the door panel 30 at a position as it is or in the vicinity thereof.
Power window glass regulator 1 even if 1 is used
There is no obstacle to the installation of the.

Further, when the power window glass regulator 1 is mounted in the door panel of the vehicle, the wire holding portion 13 of the clip 11 engaged with the drive wire 4 and the door panel 3 due to a vehicle assembly error or the like.
Even if the position of the through hole 31 of 0 does not exactly match,
The outer peripheral surface of the drive wire 4 and the inner surface of the wire holding portion 13 are frictionally engaged with each other, and a gap 28 is formed between both side surfaces of the drive wire 4 and the inner surface of the wire holding portion 13. Since the drive wire 4 easily shakes toward the clip, the wire holding portion 13 slightly slides in the longitudinal direction of the drive wire 4 due to the shake behavior of the drive wire 4 accompanying the initial opening and closing of the door window glass, and the clip 11 It is possible to automatically and easily adjust the holding position of the drive wire 4 by means of, so that the deflection suppressing action of the drive wire 4 by the clip 11 can always be most effective.

The left and right arms 14 and 1 of the clip 11 are also
5 is engaged with the notch 20 by the hook 23 and the recess 25 of the overlapping portion 17 with the protrusion 27 of the overlapping portion 18, so that the closed state of FIG. Since the drive wire 4 can be frictionally engaged with the drive wire 4 and the notch 20 and the hook 23 are provided relatively close to the wire holding part 13, the frictional engaging force of the drive wire 4 in the wire holding part 13 is increased. Since the notches 20 and the hooks 23 can be accurately regulated, the left and right arms 1 of the clip 11 can be used for transportation of the assembled power window glass regulator 1.
It is surely prevented that the clips 4 and 15 are opened and the clip 11 is disengaged from the drive wire 4, or the engagement position of the clip 11 with respect to the drive wire 4 is deviated, which is very safe in practical use.

Further, the notches 20 and the hooks 23 on the left and right arms 14 and 15 are engaged with each other, and the recess 2 of the overlapping portion 17 is formed.
5 and the engagement of the protrusion 27 of the overlapping portion 18 refer to FIG.
Therefore, it is necessary to disengage the respective engaging portions in the front, rear, upper, and lower directions when opening the left and right arms 14 and 15, and the protrusion 27 and the recess 25 are used. The disengagement sections 17, 18 to disengage
When the left and right arms 14 and 15 are relatively expanded in the vertical direction, the relative displacement of the left and right arms 14 and 15 in the vertical direction is caused by the hook 23 contacting the bottom of the notch 20 and the upper surface of the rib 19. Restrained, notch 20 and rib 19
Since the engagement between the hook and the hook 23 functions as a kind of stopper against the vertical displacement of the arms 14 and 15, it is difficult to open the left and right arms 14 and 15 from these surfaces, and the closed state is easily maintained. There is an advantage that the frictional engagement action of the clip 11 holding the drive wire 4 can be exhibited more reliably.

Next, in the embodiment of FIG. 6, a space 4 surrounded by a thin wall is formed in the wall surface of the wire holding portion 13 of the clip 11.
0 is formed so that the elasticity of the inner surface of the wire holding portion 13 becomes relatively large, and the left and right arms 14 and 15 of the clip 11 are closed as shown in the drawing, and the wire holding portion 13 is provided with a drive wire. 4 is held, the drive wire 4 is elastically sandwiched in the wire holding portion 13 by the elasticity of the outer peripheral surface of the outer cable 7 and the elasticity of the inner surface of the wire holding portion 13 due to the void 40, and the clip 11 is As a result of frictionally engaging the drive wire 4 with an appropriate strength, the clip 11 can also achieve the same effect as that of the above embodiment.

Further, in the embodiment of FIG. 7, the projection 50 is formed on the inner peripheral surface of the wire holding portion 13 of the clip 11,
The left and right arms of the clip 11 are closed as shown,
When the drive wire 4 is held in the wire holding portion 13,
The projection 50 sandwiches the outer peripheral surface of the drive wire 4 so that the sliding between the two becomes relatively good, and the frictional engagement force of the drive wire 4 by the wire holding portion 13 can be finely adjusted. It is possible to obtain the same operational effect as in the above case.

In each of the above embodiments, the clip is frictionally engaged with the drive wire extending between the winding drum of the power window glass regulator and the upper end of the guide rail, but the clip is frictionally engaged. The frictional engagement position of the clip with respect to the drive wire may be appropriately shifted according to the vibration mode of the drive wire accompanying the raising and lowering of the window, and when the window glass is lowered, the drive extending between the winding drum and the lower end of the guide rail is extended. When the window glass approaches the wire and the vibrating drive wire may come into contact with the window glass, it goes without saying that the clip may be frictionally engaged with the drive wire at this portion. In addition, even if the same configuration as that of each of the above-described embodiments is added to the manual window glass regulator, In which it is possible to obtain the same effects as.

[0020]

In the window glass regulator according to the present invention, when mounted on a vehicle, the drive wire between the winding drum and the guide member is locked by the clip, and the vibration thereof can be reliably suppressed. On the other hand, frictional engagement of the clip with the drive wire at an appropriate position facilitates the work of attaching the window glass regulator to the vehicle, and the initial vibration of the drive wire after attachment of the window glass regulator causes the drive wire to move. The frictionally engaged clip displaces in the longitudinal direction of the drive wire and is automatically adjusted to the appropriate position, so that the vibration suppression effect of the drive wire is always exerted effectively and the interference between the window glass and the drive wire. Can be reliably prevented.
