Abstract

PURPOSE:To improve durability by preventing large friction from being generated in an internal part bottom surface of a glass run. CONSTITUTION:A holder 7 is fixed to an edge part in a longitudinal direction of a door glass 5, and a roller 8 possible to come into contact with an inside bottom surface of a glass run 2 is rotatabiy supported to this holder 7 so as to prevent large friction from being generated in the inside bottom surface of the glass run 2 even when the door glass 5 is tilted to move at its lift time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door glass guide structure.

[0002]

2. Description of the Related Art As a vehicle door glass guide structure,
Conventionally, a device as shown in FIGS. 15 and 16 has been devised.

In this guide structure, a glass run 2 made of rubber is mounted inside a door sash 1.
The inner lip 3 and the outer lip 4 guide the vertical movement of the door glass 5. A low-friction material 6 having excellent slidability is applied to or adhered to the inner bottom surface of the glass run 2, and the edge surface of the peripheral edge of the low-friction material 6 covers the low-friction material 6 when the door glass 5 moves up and down. It is designed to slide. This similar structure is shown, for example, in Japanese Utility Model Publication No. 62-6883.

[0004]

However, in this conventional guide structure, when the door glass 5 tilts as shown by the chain double-dashed line in FIG. Since the inner bottom surface of the glass run 2 is strongly contacted, there is a problem that the low friction material 6 is easily worn over time.

Therefore, the present invention is intended to provide a vehicle door glass guide structure having high durability and capable of always smoothly operating.

[0006]

As a means for solving the above-mentioned problems, the present invention provides a vehicle door glass guide structure for guiding a door glass by means of a glass run mounted inside a door sash. A rotating body that can come into contact with the inner bottom surface of the glass run is provided in the section.

[0007]

Since the edge portion of the door glass contacts the inner bottom surface of the glass run through the rotating body, even if the door glass tilts during the lifting operation, the friction generated on the inner bottom surface of the glass run is small.

[0008]

EXAMPLE An example of the present invention will be described below with reference to FIGS. The same parts as those of the conventional one shown in FIGS. 15 and 16 are designated by the same reference numerals.

First, the first embodiment will be described.

1 to 4, reference numeral 5 denotes a vehicle door glass, and resin holders 7 are integrally fixed to the front and rear longitudinal edges of the door glass 5 by means such as adhesion. .. The holder 7 is formed by bending in a step shape from the base portion to the tip portion, and a vertical groove 9 for accommodating the roller 8 is provided at the tip portion. Then, the pair of vertical walls 1 forming the vertical groove 9 of the holder 7
Support holes 11 and slits 12 are provided in the vertical positions 0 and 10 at predetermined intervals in the vertical direction, and the shaft 13 of the roller 8 is fitted into the support holes 11 through the slits 12 as shown in FIG.

Reference numeral 1 denotes a door sash having a U-shaped cross section. Inside the door sash 1, a glass run 2 made of rubber is mounted. The glass run 2 has an inner lip 3 and an outer lip 4 extending from the ends of a pair of side walls, and the inner lip 3 is lifted when the door glass 5 is moved up and down.
And the outer lip 4 are the vertical walls 10 and 10 of the holder 7.
The door glass 5 is elastically contacted with the door glass 5 to guide the door glass 5 to a predetermined position, and at the same time, the door glass 5 and the door sash 1 are reliably sealed. Also, grass run 2
The roller 8 comes into contact with a portion of the inner bottom surface of the roller corresponding to the vertical edge of the door glass 5.

In the case of this guide structure, since the longitudinal edge of the door glass 5 contacts the inner bottom surface of the glass run 2 through the plurality of rollers 8, the friction with the inner bottom surface becomes extremely small, and when the hoist is moved up and down. Even if the door glass 5 tilts to locally increase the pressure contact load against the inner bottom surface, the glass run 2 is less likely to deteriorate.
Further, in the case of this embodiment, since the holder 7 is formed by bending it in a step shape from the base portion to the tip portion, the door glass 5
Can be made substantially flush with the outer wall of the door sash 1, and the flush surface of the vehicle body can be realized.

Next, a second embodiment of the present invention will be described with reference to FIGS.

In this embodiment, only the arrangement of rollers is different from that of the first embodiment, and the construction of the other parts is the same as that of the first embodiment. That is, in the case of this embodiment, the rollers 8 which come into contact with the inner bottom surface of the grass run 2 are arranged at the upper and lower corners of the holder 7, respectively, and the rollers 8 contacting the outer side walls of the grass run 2 are provided at the intermediate portions thereof. A roller 18 is provided in contact therewith. The roller 8 has a function of reducing friction against the inner bottom surface of the Guslan 2 like the first embodiment, and the roller 18 has a function of suppressing an increase in contact pressure between the holder 7 and the outer lip 4. Have.

Generally, since the outer surface of the vehicle body is curved,
When the door glass 5 is moved up and down, the holder 7 strongly pushes the outer lip 4 side, and the contact pressure between the holder 7 and the outer lip 4 rises. However, in the case of this embodiment,
Since the roller 18 is arranged in the holder 7 and the strong contact between the holder 7 and the outer lip 4 is avoided by the action of the roller 18, it is possible to obtain a smoother raising / lowering operation of the door glass 5, and the glass run. The durability of 2 is also improved.

Next, the third, fourth and fifth embodiments of the present invention will be described.

In the third embodiment, as shown in FIGS. 8 and 9, balls 20 are provided at the upper and lower ends of the holder 7 in place of the rollers 8, and each ball 20 has a claw 21 formed integrally with the holder 7. It is rotatably supported by and comes into contact with the inner bottom surface of the grass run. As a modification of this,
As shown in 0, attach the holders 7a and 7b that support the sphere 20.
It is also conceivable that the holders 7a and 7b are divided into two parts and fixed to the upper and lower ends of the door glass 5.

In the fourth embodiment, as shown in FIGS. 11 and 12, a plurality of spheres 2 are provided on the holder 7 at predetermined intervals in the vertical direction.
2 is provided, and each sphere 22 is rotatably supported by a spherical groove 23 formed in the holder 7, and abuts on the inner bottom surface of the grass run.

In addition, the fifth embodiment is a further improvement of the fourth embodiment. As shown in FIGS. 13 and 14, not only the inner bottom surface of the glass run 2 but also the side wall on the outer side of the vehicle and the inner side of the vehicle as shown in FIGS. It also comes into contact with the side wall of the.

In any of these embodiments, the door glass 5 comes into contact with the inner bottom surface of the glass run 2 through the sphere 20 or 22 as a rotating body, so that when the door glass 5 moves up and down, the inner bottom surface of the glass run 2 is moved. There is no big friction between and.

[0021]

As described above, according to the present invention, a rotating body capable of contacting the inner bottom surface of the glass run is provided at the edge of the door glass so that the inner bottom surface of the glass run is large even if the door glass tilts during the lifting operation. Since no friction occurs, the durability is greatly improved compared to the conventional one.
