Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a launch channel that is attached to a door sash, and particularly to a launch channel that includes a pair of lip portions that sandwich a door glass.

(Prior Art) A door glass is attached to a door sash on a door panel of a vehicle via a launch channel.
This door glass is moved vertically by a suitable window regulator, supported at a desired height by a door sash, and a launch channel fills the gap between it and the door sash to prevent noise generation due to the vibration of the door glass. Preventing.

Normally, the launch channel is formed from a single approximately belt-shaped flexible material, which is bent to form a pair of vertical lines that slide against both ends of the door glass 1, as shown in FIG. It is divided into a section 2 and an upper end section 3 that connects both vertical sections. Furthermore, the launch channel has a uniform cross-sectional shape, and is shaped to fit into the door sash 4 having a U-shaped cross section and to sandwich the side edge of the door glass 1, as shown in FIG.

(Problem that the invention aims to solve) By the way, when the door glass is at the lowest position, there is no problem if both upper corners of the door glass are held between the launch channel, but if they are separated downwards, the window reg. When the door glass is raised by the urator, the following problems occur. That is, if both upper corners of the door glass 1 form a right angle as shown in FIG. 6, and the longitudinal direction of the vertical part 2 of the launch channel is arranged parallel to the vertical direction of the door glass, A pair of lip parts 5 whose upper edges at both upper corners of the door glass 1 are located at the lower ends of the vertical part 2 (see FIG. 4).
The door glass contacts the lip end C of the door in a surface contact state, and the smooth lifting of the door glass is obstructed.

The purpose of the present invention is to provide a launch channel that allows the door glass to rise smoothly.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention supports a door glass having an outer shape in which both upper corners form right angles, and supports the door glass in a slidable manner with respect to the up-and-down direction of the door glass. a central sliding contact portion that is attached to the door sash with its longitudinal direction parallel to the door sash and that slides into contact with the side end surface of the door glass to prevent the door glass from shifting in the lateral direction along the glass surface; A pair of side pieces that extend from both ends of the contact portion in the lateral direction along the glass surface and come into contact with both the front and back glass surfaces of the door glass to prevent the door glass from shifting in the glass thickness direction. and a pair of lip portions extending toward the central sliding contact portion from the root portions formed by the tips of the both side pieces, and the lip ends of which abut each other so as to be able to come and go elastically. Particularly, the cut surface of the lower end of the launch channel is formed at an angle of inclination with the lip end side being above the root side.

(Function) Since the cut surface of the lower end of this launch channel is formed at an angle of inclination with the lip end side upwards from the root side, the rising door glass will first
It makes point contact with the base side of the pair of lip parts and presses the contact part, thereby acting to push open both lip ends, thereby facilitating the subsequent lifting of the door glass.

(Example) FIG. 1 shows a launch channel as an example of the present invention. This launch channel is attached to the door sash shown in Fig. 6, and its shape is the same as that shown in Fig. 5 except for the lower ends of both vertical parts 2, so the same parts are given the same symbols here. The redundant explanation will be omitted.

The launch channel according to the present invention shown in FIG. 1 has a uniform cross-sectional shape in the longitudinal direction. That is, the second
As clearly shown in the figure, there is a central sliding contact part 7 that makes sliding contact with the side end surface of the door glass 1 and restricts the movement of the door glass in the lateral direction Y along the glass surface, and A pair of side pieces 5, 5 that extend in the lateral direction Y, sandwich both the front and back glass surfaces of the door glass 1, and restrict movement in the glass thickness direction X, and the tips of these side pieces. It is formed of a pair of elastically deformable lip portions 6, 6, which extend from the root portion a formed by the grooves toward the central sliding contact portion, and whose tip lip ends c abut against each other.

The lower ends of both vertical portions 2, 2 of such a launch channel are cut along a cutting surface that maintains an inclination angle θ (approximately 30° to 60°) with the horizontal plane. Therefore, at the lower end, the pair of side pieces 5, 5 have a tip side thereof,
That is, the ends of both lip parts 6, 6 facing the root part a are at the lowest position, and the central sliding contact part 7 on the lip end c side is maintained at the highest position. In particular, at the lower ends of the pair of lip parts 6, 6, both root parts a, a, which are the distal ends of the side pieces 5, are separated from each other by keeping a distance b, and the lip ends c, which are the distal ends of the lip parts 6, That is, the positions closest to the central sliding contact portion 7 are in contact with each other.
However, when the door glass 1 is held between the lip parts 6, 6, they can be elastically deformed so that the lip ends c sides are separated by the thickness of the glass.

With respect to such a launch channel, when the door glass 1 guided by the launch channel is at the lowest position (the position shown by the solid line in Figure 1), both upper corners of the door glass and both lower ends of the vertical portion 2 are Assume that they are far apart.

When the door glass 1 rises and first reaches the bases a, a of the lip portions 6, 6 (the position indicated by the broken line in FIG. 1), at that time, as shown in FIG. The upper edges of both upper corners of the glass 1 fit between the two root portions a, a, and then come into point contact with the lip portions 6, 6. Subsequently, when the door glass 1 rises, the contact area of both upper corners of the door glass 1 increases along the cut surfaces of both lip parts 6, 6, and at the same time, both lip parts 6, 6 touch both the front and back glass. The lip ends c, which were in contact with each other, are pushed apart by the glass thickness t.

Therefore, when the door glass 1 is raised to the position shown by the two-dot chain line in FIG. (See Figure 3b), the door glass 1 can smoothly deform from contact with the lip part 6 at the lower end of the launch channel to fitting, and the door glass can be moved up and down smoothly. Channel cutting is also easy, and increases in processing costs can be easily suppressed.

In the above-mentioned place, both vertical parts 2 of the launch channel
The lower end of the door glass 1 is fitted into the rising door glass 1 at the same time, but instead of this, in the case where one of the vertical parts 2 always fits and holds one side edge of the door glass 1, only the other side can be fitted into the lower end of the door glass 1. The lower end may be formed in the shape shown in the figure.

(Effects of the invention) The launch channel of the present invention can smoothly insert and raise the door glass that rises from a position away from the lower end, and can smoothly perform the raising operation of the door glass. It also improves the durability of the launch channel itself.
