Description

[Detailed Description of the Invention] This invention relates to a glass guide device in a glass lifting device for an automobile door.

As a conventional glass guide structure for an automobile door, for example, as shown in FIG. 1, the front and rear edges of the door glass 50 are engaged with the lower sashes 3 and 4 arranged in parallel inside the door sash 1 and the door panel 2, and the door glass 50 is moved up and down (not shown). There is a structure in which the glass that is raised and lowered by a mechanism is guided by a satshu.

However, in the above-mentioned glass guide structure, when the door glass 54 is placed under the door glass 54, the rear edge of the glass is moved by the glass run rubber 6 disposed in the recess 1a inside the door sash 1 as shown in the cross-sectional view of FIG. However, the front beveled edge 5a of the door glass is about to come off the door sash 1.

For this reason, especially when driving at high speeds, the pressure on the outside of the door glass becomes much more negative than that inside the car, and the door glass is sucked out of the car. This makes it difficult for the glass to enter the glass run rubber 6, making it difficult to close the door glass.

There were drawbacks such as increased wind noise due to the gap between the edge of the glass and the lid.

This idea was made by focusing on the above-mentioned drawbacks, and a sliding piece that can be engaged with the inside of the door glass is fixed to the part of the door glass that is always engaged with the door opening. By sliding the glass to guide the glass, and attaching a glass run rubber along the inner edge of the door sash than the sliding piece,
The purpose is to minimize the amount of displacement of a door glass due to negative pressure outside the vehicle even when driving at high speed.

Embodiments of this invention will be described below based on the drawings.

FIG. 4 shows a door glass to which the present invention is applied, and shows suitable portions of the door glass 5 that are always engaged with the door-side satush,
For example, as shown in FIG. 4, slide pieces 8 made of synthetic resin or the like are fixed to the upper rear edge, lower rear edge, and lower front edge of the door glass 5, respectively.

That is, this slide piece 8 has a substantially rectangular cross section as shown in FIG. 5, and is provided with a groove 8a having the same width as the thickness of the glass. They are put together and fixed with adhesive or the like.

This slide piece 8 is slidably engaged in the engagement recess 1a inside the door sash 1 as shown in FIG.

Also, the door sash 1 is located inside the slide piece 8 mentioned above.
A glass run rubber 9, 9 is attached to the end portions 1b'' and lbg of the door sash 1, respectively, and the glass run rubber 9 is attached to the engaging portion 9a of the door sash 1.
and a lip 9 protruding into the recess 1a of the satush.
b, and this lip 9b is in contact with the door glass 1.

In addition, 10 is a door weather strip arranged and fixed along the outside of the door sash 1.

In this way, in this invention, the door glass 5 is guided by the sliding pieces 8 fixed to appropriate locations on the door glass 5 moving around inside the sash.

As explained above, the glass guide device according to this invention is applied to an automobile door with a sash having a glass lifting device, and is capable of engaging with a recess inside the sash at a portion of the door glass that is always engaged with the sash. Since the sliding piece is fixed and a glass run rubber is attached along the inner edge of the sliding piece of the satsume, even if the outside of the glass becomes considerably negative pressure than the inside of the car when driving at high speed, The sliding piece described above makes the amount of displacement of the door glass in the outward direction of the vehicle extremely small, so when the glass is raised, the upper edge and beveled edge of the glass are smoothly engaged with the glass run rubber, ensuring reliable operation even when driving at high speeds. The door glass can be closed, which has the effect of not increasing wind noise.
