Abstract

PURPOSE:To improve the door glass guiding performance by cutting the corner at the lower edge of a lip at the opened edge of a corner piece glass run aslantly in the larger angle than the inclination angle of the front edge of a glass and setting the top contact position of the door glass onto the guide groove bottom. CONSTITUTION:The corner part 60b at the lower edge part 60a of the outer side lip 60 of a corner piece glass run 50 is cut aslantly in an inclination angle betalarger than the inclination angle alpha of the front edge 4a of a door glass 4, and the top contact position Q of the door glass 4 is set on the groove bottom part 8a side of the guide groove 8 of the corner piece glass run 50. With such constitution, the span (l) from the groove bottom 8a of the rear edge 60c at the lower edge part of the outer side lip 60 is reduced, and the rigidity for bending increases. With such constitution, the smooth rising and lowering of the door glass is permitted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a corner piece glass run that is attached to a corner piece provided at the front end of the door waist portion of a front door of an automobile.

Conventional technology As shown in Fig. 4, in an automobile, the front door 1
At the 4IT end of the door waist part 2, there is a door mirror l (not shown).
It is known to be provided with a corner piece 3 for attachment.

A corner piece glass run is usually attached to this corner piece 3 to guide the front edge of the door glass 4 up and down and seal it, but in the case of a satsuri-less type automobile, it is installed as shown in Fig. 5. (-) There is a corner bead glass run 5 integrally formed from the oblique front edge to the rear edge of the corner piece 3. -11222
It is disclosed in the publication No.

As such corner piece grass run 5 will be explained with reference to FIG.
Outer 11111 lip 6 and inner tall lip 7
This forms the kite groove 8 of the door glass 4.

The lower end portions 6a and 7aH of the outer lip 6 and the inner lip 7 are formed to diverge toward each other so that the door glass 4 can be moved up and down smoothly. The spread dimensions, etc. are set so that it can be guided reliably when ascending.

Problems to be Solved by the Invention When the upper end portion of the door glass 4 that rises is located at the lower end central portion A of the outer lip 6 and the inner lip 7 as shown in FIG. However, in some cases, for example, the lower end 6a of the outer lip 6 is bent inward as shown by the broken line, and the upper end of the door glass 4 is on the outer side. lip 6
Position Bl offset to the outside of the vehicle from the lower end 6a: If the door glass 41 rises in some cases, the door glass 4
It has been pointed out that it rides up to the outside position @C of the outer lip 6 and comes off.

This phenomenon of the door glass 4 coming off is mainly caused by the swing of the door glass 4 in the vehicle width direction when the door glass 4 is fully opened. The inner lip 7 may come off toward the passenger compartment, but since the door glass 41 is curved to follow the shape of the side surface of the vehicle, the rear end 6b of the outer lip 6 is removed when the door glass 4 is raised. Because of this, the outer lip 6 often comes off on the outside of the vehicle.

Further, when the door glass 4 is raised, the first contact position P of the corner piece glass run 5, which the front R4m of the door glass 4(') comes into contact with first, is on the outer side which is away from the groove bottom 8 & of the kite groove 8 by a span L in the front-rear direction. Since this is the rear end 6b of the lip 6, when the rear end 6b of the outer lip 6 is bent inward when the door glass 4 is lowered, the amount of deflection becomes large and the stiffness is weak, causing the door to Even if the glass 4 is slightly shaken, the door glass 4 is likely to come off due to poor guidance when the door glass 4 is raised.

Therefore, the present invention provides a corner piece glass run that can reliably guide the door glass even when the door glass is shaking in the vehicle width direction.

Means for Solving the Problems] - The corner portion of the lower end of at least the outer lip of the book side lip and the inch side lip formed on the opening edge of the narrow piece glass run is set at an angle greater than the inclination angle of the leading edge of the door crow. The corner piece is cut out diagonally, and the position where the door glass fits is set at the bottom of the groove of the corner piece glass run.

When the door glass is raised from the fully open position, the corner piece glass run is moved from the door glass end contact position set at the groove bottom extension of the lower end of the outer lip to the outer lip and inch side of the corner piece glass run. The lips are guided.

Therefore, even if the door glass is tilted upward in the vehicle width direction, the position where the door glass tip touches is on the groove bottom side of the corner piece glass run, and the lower end of the outer lip is deflected toward the guide groove side. 1t is less than t, and the door glass is prevented from coming off due to internal defects.

EMBODIMENT MU Below, an embodiment of the present invention will be described in detail with reference to the drawings, with the same reference numerals substituting the same parts as the conventional structure.

In FIGS. 1 to 3, a guide ss'v for the door glass 4 is formed at the rear part 50a of the corner piece glass run 50 by an outer side lip 7 and an inner side lip 7.

Corner portion 60 of the lower part 60ai of the outer lip 60
b is obliquely cut out at an angle β larger than the inclination angle α of the front edge 4a of the door glass 4, and the groove bottom 8 & It is set on the side.

Therefore, as shown in figure fjIlc3, the outer (II
The span t of the rear end 60a of the lower end of the IJ knob ω from the groove bottom 8a is shortened, and the rigidity against bending is increased, and the above-mentioned rear part 60C of the actor side lip 60 is bent toward the passenger compartment side.
〈Even if it were to bend, the bending force would be small.

According to the above embodiment structure, the corner portion Sob of the lower end portion 60a of the outer lip 60 which is normally easily bent to the outside of the vehicle interior.
fl notch, and the span t from the groove bottom 8a of the guide groove 8 to the rear end 60C of the lower edge of the upper outer lip is short, so if the rear end 60C is bent toward the single chamber side. Even if the door glass 4 swings toward the outside of the vehicle, the door glass 4 will not cause poor guidance and will not come off.

In this way, the rising door glass 4 is smoothly guided by the obliquely cut outer lip 60 and the inner (III lug 7).

In the above embodiment, the corner portion 60b of the lower end 60a of the outer lip 60 is notched, but the door glass 4
If the inner lip 7 tends to come off toward the passenger compartment side, the lower end of the inner lip 7 can be cut out in a diagonal manner in the same way as the outer lip 60.

Effects of the Invention According to the present invention, at least the corner portion of the lower end of the outer lip of the outer lip and the inner lip formed at the opening edge of the corner piece glass run is connected to the front edge of the door glass. The corner bead is notched diagonally at an angle greater than the inclination angle and is set at the bottom of the corner bead glass run groove where it touches the front of the door glass, so the lower end of the outer lip or the lower ends of each of the outer lip and the inch lip. This has great practical effects in that it reliably prevents poor guidance of the door glass due to bending, and allows the door glass to be smoothly guided up and down and sealed.
