Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement in the connection structure between a window glass and a window regulator in an automobile.

[Conventional technology]

Conventionally, the connection structure between the window glass and the wind regulator in a wire-type wind regulator is to fix a glass holder to the lower end of the window glass, and tighten the lower end of the glass holder and the carrier plate on the wind regulator side with bolts and nuts. were connected by. Note that the carrier plate has resin holding members attached to various parts thereof, and the grooves or locking parts formed in the holding members are engaged with the edges of the rails arranged in the vertical direction. It is a device that slides, and is raised and lowered by circulating the wire in the vertical direction.

[Problem that the invention attempts to solve]

By the way, in this conventional coupling structure, the rail and carrier plate engage with each other with almost no play,
Further, since the carrier plate and the window glass are also connected in a completely fixed state, the following problem arises.

That is, as shown in FIG. 2, the front and rear edges of the window glass 3 slide while being guided by the front guide member 22 and the rear guide member 21 that integrates the door sash part 21a and the guide part 21b. A clearance of several millimeters is provided between the window glasses to ensure smooth sliding. However, structural conditions such as when the parallelism of the guide member itself is out of order, when the rail and guide member are not parallel, and when the rail is gently curved when viewed from the front, as well as actual manufacturing errors and assembly Due to installation errors, changes over time due to use, etc., the window glass may shift beyond the above-mentioned clearance.

In the end, such deviation of the window glass impairs the followability and operational feel during opening/closing operations, causes unnecessary abnormal noises and malfunctions, and causes the windshield 3 to move against the rear guide member 21. If only a portion of the gear is in contact with the other gear, the so-called stuck phenomenon occurs due to friction, which causes gear-shifting movement and discontinuous noise.

[Means for solving problems]

The purpose of the present invention is to provide a joint structure for a wind regulator and a window glass that solves the problems existing in the prior art described above.
This is achieved by the bonding structure shown below.

That is, the coupling structure M according to the present invention connects the carrier plate 2 of the wind regulator 1 and the window glass 3 by a pair of rotatable link members 4 and 5 that are spaced apart from each other and are substantially parallel to each other. At this time, according to an optimal embodiment, at least one of the link members 4 and 5 is connected to the carrier plate 2 or the window glass 3 so that the position can be adjusted, and the upper part of each link member 4 and 5 is tilted rearward at a predetermined angle. , so that the entire surface of the window glass 3 is brought into contact with the guide member 21 on the side to which it is pressed by its own weight.

[Effect]

Next, the operation of the present invention will be explained.

The coupling structure M according to the present invention allows the windshield 3 to
In particular, the rear edge portion can be brought into full contact with the rear guide member 21. Furthermore, since the window glass 3 can move substantially parallel to the carrier plate 2, positional errors that exist in the rear guide member 21 that occur during manufacturing, assembly, etc. can be absorbed. Furthermore, by appropriately selecting the inclination angles of the link members 4 and 5, the window glass 3 comes into contact with the rear guide member 21 with an appropriate pressing force due to its own weight, and is stably held.

〔Example〕

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

Fig. 1 is a front view showing a coupling structure between a wind regulator and a window glass according to the present invention, Fig. 2 is an inner configuration diagram of the entire automobile door including the coupling structure, and Fig. 3 is A--A in Fig. 1. The A-line sectional view and FIG. 4 are front views of the connection position adjustment section in the same connection structure.

First, in order to clarify the present invention, the general structure and function of the entire wind regulator 1 will be explained with reference to FIG.

20 is a car door. The window regulator 1 is disposed on the inner surface 24 of the main body of the door 20, and a front guide member 22 and a rear guide member 21 are disposed in front and behind the door 20, respectively. In addition,
The rear guide member 21 has an upper half extending upward from the inner surface 24 of the main body to form a door sash portion 21a, and a lower half thereof forming a guide portion 21b.
Further, the rear guide member 21 and the front guide member 22 are parallel to each other, and their upper sides are inclined rearward at a predetermined angle. Then, the window glass 3 is connected to each guide member 2.
It is slidably held in guide grooves formed at 1 and 22.

On the other hand, the wind regulator 1 is provided with a guide rail 6 parallel to the guide members 21 and 22, and the carrier plate 2 is slidably mounted on this rail 6 by a holding block 26 (see Fig. 1). In addition, wire guides 27 and 28 such as pulleys are provided at the upper and lower ends of the guide rail 6. Further, the inner surface 24 of the main body in front of the guide rail 6 is provided with a rotating drum 29 that is rotated by an operating section. Then, the rotating drum 2
9. The carrier plate 2 is fixed to a wire 30 spanned between the wire guides 27 and 28, and the carrier plate 2 is configured to be raised or lowered by rotating a rotating drum 29.

The carrier plate 2 and the lower end of the window glass 3 are coupled by a coupling structure M according to the present invention.

Next, regarding the bonding structure M according to the present invention, the first
This will be explained with reference to FIGS. 3 and 4.

First, two spaced apart locations on the front and rear of the carrier plate 2 and two spaced apart locations on the front and back of the window glass 3 are connected by link members 4 and 5 having the same length and arranged substantially parallel to each other. Thereby, the window glass 3 can be moved parallel to the carrier plate 2. Each of the link members 4, 5 is formed of, for example, an elongated plate, and the upper and lower ends of each of the link members 4, 5 are rotatably attached to the carrier plate 2 and the window glass 3 via rotation shafts 11, respectively. In this case, in order to make the link members 4 and 5 as long as possible, it is desirable that the connection position with respect to the carrier plate 2 be selected on the lower side.

Moreover, the window glass 3 and the link member 4 or 5
As shown in FIGS. 3 and 4, one of the two is connected via a connection position adjustment part P that can arbitrarily change the connection position. That is, a long hole 7 in the longitudinal horizontal direction is formed in the window glass 3, and a collar 9 is attached to the long hole 7, which is positioned and fixed by tightening and loosening a nut 8. The collar 9 has a flange portion 9a formed at one end and a threaded portion 9b formed at the other end. A support pin 10, which is caulked at one end, is inserted into the collar 9 and the link member 4, and the collar 9 and the link member 4 are rotatably connected. Due to such an adjustment part P, during assembly, the rear edge of the window glass 3 can be completely brought into contact with the rear guide member 21 over the entire range, so that it slides smoothly.

Further, the link members 4 and 5 in the attached state of the window glass 3, the window regulator 1, and the door 20 are inclined at a predetermined angle α with respect to the guide rail 6. Note that the selection of this angle α is important.
That is, in the present invention, since the window glass 3 is set in a displaced state, the rear guide member 21 is in this state.
It is necessary for the window glass 3 to be stably held by its own weight, and on the other hand, when the window glass 3 is displaced in the front-rear direction, it is necessary to suppress the displacement in the vertical direction. Therefore, for example, if the length of the link members 4 and 5 is set to 60 mm and the upper side is selected at an angle α that tilts backward by approximately 5 degrees, the vertical displacement of the window glass 3 is 5.23 mm while the horizontal displacement is 5.23 mm. 0.23mm for optimal results.
It was also confirmed that good results could be obtained if the angle α was within a range of about 5 to 10 degrees.

Although the embodiments have been described in detail above, the present invention is not limited to these embodiments.
For example, the adjusting portion P may have a different structure and may be provided at any other connecting portion. In addition, although the window glass 3 and the link members 4 and 5 were directly connected,
It may also be of a type in which another member is interposed in between.
Other changes may be made in the detailed structure, shape, arrangement, material, quantity, etc., without departing from the gist of the present invention.

[Effect of idea]

As described above, since the wind regulator and window glass coupling structure according to the present invention connects the window glass and the carrier plate by a pair of spaced link members, the following effects can be obtained.

Windshield guide members and guide rails, including door sashes, may be subject to structural conditions, manufacturing errors,
Even if the window glass is in a biased position due to assembly errors, changes over time, etc., the window glass can also be displaced (translated) accordingly, so that the bias can be absorbed. Therefore, it is possible to dramatically improve followability and operational feel when opening and closing the window glass.

Since the entire mechanism is not strained, it is possible to prevent failures and improve durability, thereby achieving improved reliability and longer life.

According to the optimal embodiment, the connection position of the link member is variably set, and the rear edge of the windshield and the guide member are placed in a parallel relationship, so the entire range of the rear edge is in contact with the guide member, eliminating the so-called stuck phenomenon. , prevention of abnormal noise and smoother sliding are guaranteed.
