DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass run-type molded part structure on which a door glass of an entrance door of an automobile slides.

[0002]

2. Description of the Related Art In the drawings, a symbol is used in which one of the median lines from the apex angle of an isosceles triangle is painted, and the painted side represents a molded part, and the non-painted side is extrusion molded. Part. Conventionally, as shown in FIGS. 1 to 3, the door frame 2 is mounted along an inside of a door frame 2 provided in an upper half portion of a door 1, and seals a space between a door glass 5 that moves up and down and the door frame 2. In the vertical part, the glass run 20, which guides the vertical edge 5a of the door glass 5 from both sides thereof,
30 is attached. More specifically, the glass runs 20 and 30 are provided with seal lips which elastically contact with both ends of the opening of the groove-shaped bases 21 and 31 fitted to the retainer 3 inside the door frame 2 with the door glass 5 interposed therebetween. 22, 23, 32 and 33 are protruded.

The glass runs 20 and 30 are mostly formed of extruded products, but L-shaped products are arranged and joined at corners where a vertical portion and a horizontal portion intersect. The extruded product is obtained by co-extruding a synthetic resin on the surface of rubber, and the surface of the synthetic resin is roughened by blasting.
Low sliding resistance and high durability.

[0004] On the other hand, since the corner portion made of a molded product is made of a synthetic resin to which no treatment is applied,
As compared with the extruded product, the sliding resistance against the door glass 5 is high, the abrasion is easy, the durability is poor, and the groove bottom wears while repeating the friction with the ascending and descending door glass 5, and the door glass 5
This raises a problem that a regulator (not shown) built in the door 1 may malfunction.

[0005]

The problem to be solved is that the structure of the conventional glass run type molded product is such that the corner portion is easily worn as compared with the extruded product, and the friction with the ascending and descending door glass 5 is repeated. The groove bottom 34 wears and hinders the ascending and descending of the door glass 5, so that a regulator built in the door 1 causes a malfunction, and the present invention has solved the above problem and has excellent durability. A glass run structure is provided.

[0006]

Means for Solving the Problems As shown in FIG. 1, FIG. 2 and FIG.
Seal lips 22, 23, 42, and 43 are provided at both ends of the opening portions of the opening portions 1 and 41 so as to elastically contact with the door glass 5 therebetween.
And a glass run attached along the inside of the door frame 2 provided in the upper half of the door 1 to seal between the door glass 5 and the door frame 2 moving up and down. Has a groove-shaped base 4 of a molding corner portion F which is continuous with the extrusion vertical portion E.
A glass sliding member 46 is affixed to the bottom 44 of the first groove.
Moreover, at the boundary G between the extruded vertical portion E and the molded corner portion F, the glass sliding member 46 is formed along with the groove bottom 44 of the molded corner portion F by the base 2 of the extruded vertical portion E.
The groove 45 is slightly depressed 45 with respect to one groove bottom 24 and gradually rises up to the height of the groove bottom 24 of the extruded vertical portion E as the boundary G is separated.

According to the present invention, the glass sliding member 46 which is affixed to the groove bottom 44 of the molding corner F and is continuous with the extrusion vertical portion E is provided at the boundary G at the groove bottom of the extrusion vertical portion E. 24, when the door glass 5 rises, the upper corner 5 of the door glass 5
b does not catch on the lower end of the glass sliding member 46, and the glass sliding member 46 does not peel off.

Further, the upper corner angle 5b of the door glass 5, which continues to rise, gradually comes into contact with the glass sliding member 46 which gradually rises to the height of the groove bottom of the extruded vertical portion E as leaving the boundary G. , Edge 5a of door glass 5
However, since it slides on the glass sliding member 46 having a remarkably low coefficient of friction and excellent wear resistance, the frictional resistance is small, and even when the door glass 5 is repeatedly moved up and down, the glass sliding member 46 does not wear. Very few. Therefore, even if the door glass 5 is used for a long period of time, the door glass 5 is prevented from moving up and down,
The built-in regulator does not malfunction.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1, 2 and 4.
2 is a door frame provided in the upper half of the door 1;
Reference numeral 0 denotes a glass run for sealing between the ascending and descending door glass 5 and the door frame 2, and seal lips 22, 23, 42 sandwiching the door glass 5 at both ends of the opening of the groove-like bases 21, 41 and elastically contacting the same. , 43 are projected. The groove-shaped base 41 is fitted to the retainer 3 attached along the inside of the door frame 2.

The corner structure of the molded product will be described. The groove bottom 44 of the molded corner portion F which is continuous with the extruded vertical portion E is formed at the boundary G between the extruded vertical portion E and the molded corner portion F. It is formed so as to be depressed 45 with respect to the groove bottom 24 of the formed vertical portion E, and to gradually rise to the height of the groove bottom 24 of the extruded vertical portion E as the boundary G is separated. Further, a glass sliding member 46 is attached to the groove bottom 44 of the molding corner portion F, and the surface of the glass sliding member 46 is slightly depressed at the boundary G from the groove bottom 24 of the extrusion vertical portion E. doing.

The operation will be described below. The glass sliding member 46 attached to the groove bottom 44 of the molding corner F is formed.
However, at the boundary G between the extruded vertical portion E and the molded corner portion F, a slight depression 45 is made with respect to the groove bottom 24 of the extruded vertical portion E, so that when the door glass 5 comes up Since the upper corner 5b of the door glass 5 does not catch on the lower end of the glass sliding member 46, the glass sliding member 46 does not peel off.

Further, the upper corner angle 5b of the door glass 5, which continues to rise, is gradually reduced to the height of the groove bottom 24 of the extruded vertical portion E as it moves away from the boundary G. And the vertical edge 5a slides on the glass sliding member 46 having a remarkably low coefficient of friction and excellent wear resistance, so that the frictional resistance is small and even if the door glass 5 is repeatedly moved up and down. , Its wear is extremely low. Therefore, even if the glass sliding member 4 is used for a long time,
6 prevents the door glass 5 from moving up and down, so that a regulator (not shown) built in the door 1 does not malfunction. Examples of the glass sliding member 46 include ultra-high molecular weight polyethylene tape, polyolefin resin tape, special polyolefin resin tape, and Teflon tape, among which ultra high molecular weight polyethylene tape is preferable or limited to these. is not.

[0013]

Since the present invention is configured as described above, the glass sliding member 46 affixed to the groove bottom 44 of the molding corner F is not peeled off by the ascending door glass 5. Further, since the glass sliding member 46 has a remarkably low coefficient of friction and excellent wear resistance, even if the vertical edge 5b of the door glass 5 slides on the glass sliding member 46 repeatedly, the vertical movement is extremely high. Smooth and extremely low wear. Therefore, even if the door glass 5 is used for a long period of time, it does not hinder the raising and lowering of the door glass 5, whereby the regulator built in the door 2 does not malfunction.
