Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a vehicle window which is fixed to a vertical movement mechanism for a vehicle window glass and which is moved up and down in accordance with the operation of the vertical movement mechanism while holding the window glass. This invention relates to improvements to glass holders.

As shown in Fig. 1, this type of conventionally used vehicle window glass holder a has a U-groove c that can hold the lower edge of the window glass b, and a guide tube d fixed to the vehicle body or door, through which the guide tube d is inserted. The guide tube insertion hole e is guided and transferred by the guide tube d.
Furthermore, this holder a is used by being fixed to a guide channel g provided in a window glass drive mechanism f, and the window glass b is now placed in the U groove c of this window glass holder a. Insert and fix the lower edge of , further fix this holder a to the guide channel of the window glass drive mechanism f,
If the window glass drive mechanism f is operated after inserting the guide tube d into the guide tube insertion hole e,
Holder a, which is integrated with window glass b, is guided by guide tube d and moves up and down, whereby window glass b
The door is opened and closed. A slider integral with the holder a and having a spherical tip is provided on the inner surface of the guide tube insertion hole e so as to be in contact with the guide tube d.

However, the window glass holder a of the above conventional structure
is fixed to the guide channel g and is made of hard resin to support the guide, and the slider provided integrally with the window glass holder a is also hard. In addition, play occurs between the slider and the guide tube due to dimensional accuracy. Therefore, noise is generated due to vibrations and the like. Also, if the slider is made soft to absorb backlash, the slider and guide tube d
Due to the increased sliding resistance, the window glass holder a cannot slide smoothly against the guide tube d.
There was a problem in that the force needed to lift and lower the window glass increased.

The present invention has been made to solve these problems, and aims to prevent play between the guide tube and the slider and to allow the window glass holder to slide smoothly with respect to the guide tube. The purpose is

In order to achieve the above object, the present invention includes a hard slider with a spherical tip that contacts the guide tube on the inner surface of the guide tube insertion hole, and a soft buffer material that biases the slider toward the guide tube. Because it is hard, contact resistance with the guide tube is reduced,
In addition, the soft cushioning material absorbs play between the guide tube and the slider.

The present invention will be described below in a first embodiment shown in FIGS. 2 to 8.
This will be explained in detail based on examples.

1 is a window glass holder, and the main structure of this holder 1 is a holder body 2 molded from a hard synthetic resin. The holder body 2
is a U-groove 3 formed in a U-shaped side surface, an arm portion 4 extending from the outer surface of this U-groove 3, and a vertical line perpendicular to the extending direction of this arm portion 4 in this arm portion 4. The guide tube insertion hole 5 has a formed guide tube insertion hole 5, and a through hole 6 that penetrates toward the side surface of the guide tube insertion hole 5 is bored in the inner bottom of the U groove 3. . A slider 7 is installed in this through hole 6.
As shown in FIG. 5, it is made of hard synthetic resin and has a spherical tip and a protrusion 8 for fitting on its outer periphery. A cushioning material 10 made of a cylindrical soft material is in a compressed state in the space of the through hole closed by the rear end of the slider 7 and the glass (not shown) inserted into the U groove 3. Established in Next, 13 is a mounting screw whose head is embedded in the wall surface forming the U groove 3 of the holder body, and the head 14 of this mounting screw 13 is shown in FIGS. 7 and 8. As shown, a stepped portion 15 and notched recesses 16 are formed at regular intervals in the circumferential direction. 17 is a protrusion for reducing the contact surface with the guide tube 18 inserted into the guide tube insertion hole 5; 19 is formed on the inner surface of the U groove 3;
This is a protruding strip to prevent the adhesive filled in the U-groove 3 from spilling out.

To attach the holder 1 completed in this way to the guide channel of the window glass drive mechanism (not shown), insert the mounting screw into the mounting hole (not shown) provided in the guide channel and tighten it. This fixes the holder to the window glass drive mechanism.

According to this embodiment, since the slider 7 is hard, the contact resistance with the guide tube 18 is reduced, and the guide tube 18 and the slider 7 slide smoothly. Moreover, the soft buffer material 10 urges the slider 7 toward the guide tube, and absorbs play between the slider 7 and the guide tube. Therefore, this hard slider 7
The soft cushioning material 10 allows the window glass holder 1 to slide smoothly with respect to the guide tube without any play.

Further, the head 14 of the mounting screw 13 embedded in the holder of this embodiment has a large number of notches 16 provided in the circumferential direction, so that the mounting screw 13 can be firmly prevented from being rotated. Combined and head 1
Since the mounting screw 13 is firmly connected in the axial direction by the stepped portion 15 provided in the holder 1, the mounting screw 13 can be attached to the holder body 2 without loosening. This has the effect of being able to be firmly and reliably fixed to the glass drive mechanism.

Next, a second embodiment will be described based on FIGS. 9 to 12. The structure different from the first embodiment is that the slider 7a and the buffer material 10a are fixed to the holder 1 using rivets. The rest of the configuration is the same as the first embodiment, so the explanation will be omitted.

First, in the inner bottom of the U groove 3 of the holder 1, there is a stepped through hole 6 that penetrates toward the side surface of the guide tube insertion hole 5.
A is drilled. A slider 7a is installed in this stepped through hole 6a, and as shown in FIG. 10, this slider 7a has a spherical tip and a protrusion 8 for fitting on its outer periphery.
It is made of hard synthetic resin and further has a center hole 9. A stud 20 is fitted into the center hole 9, and as shown in FIG.
and a flange portion 22 that is engaged with the stepped portion 6a' of the stepped through hole 6a are integrally formed.
Reference numeral 10a denotes a buffer material interposed between the slider 7a and the stud 20 shown in FIG.
It has a through hole 11 through which the protrusion 21 is loosely fitted.

Next, when installing the slider 7a, the opening of the center hole 9 of the slider 7a is directed toward the U-groove 3, and the protrusion 8 of the slider 7a is
The stepped through hole 6a is fitted so that the portion a is located within the inner circumferential surface of the stepped through hole 6a. Next, apply the cushioning material 10a from the U groove 3 side.
Insert the protrusion 21 of the stud 20 into the center hole 9 of the slider through the intervening
When the slider 7a is inserted until it is positioned in the stepped portion 6a' of the stepped through hole 6a, the slider 7a is slightly bulged outward by the pressing force of the protrusion 21 of the stud 20, and the protrusion 8a
is in close contact with the inner peripheral surface of the stepped through hole 6a, and the slider 7
a is fixed to the holder body 2, and the circular tip of the slider 7a projects into the guide tube insertion hole 5.

Therefore, in this embodiment, in addition to the effects achieved in the first embodiment, the slider 7a and the buffer material 10a are
0, the slider 7a is fixed to the holder 1 by pressure, so when the holder is sub-assembled and transported, the slider 7a
Also, there is an effect that the cushioning material 10a is unlikely to fall off.

According to the vehicle window glass holder of the present invention,
Since the backlash due to dimensional accuracy and aging is absorbed by the cushioning material, there is virtually no backlash, and since the slider is hard, the holder slides smoothly against the guide tube, increasing the operating force for raising and lowering the window glass. Furthermore, it does not generate noise due to vibration.
