Abstract

PROBLEM TO BE SOLVED: To eliminate a necessity of counterboring of a sash and a weather strip by forming a weather strip mounting part of a main sash into a channel part having a substantially U-shaped cross section to store a head part of a screw member. SOLUTION: A channel part 4 having a substantially U-shaped cross section is formed on a top face of a main sash 1, and outward flanges 5 are extended at both ends of the channel part, respectively. An L-shaped bracket 7 is provided at an upper end of a partition sash 6 to fix the partition sash 6 on the main sash 1 by passing a round screw 10 into a hole 8 thereof and a hole 9 of the main sash 1. Then, locking parts 12, 12 of a door side weather strip 11 are engaged with the flange parts 5 of the channel part 4 to mount them. Consequently, it is unnecessary to form counterboring for avoiding the interference with a head part of a screw member in the main sash 1 and the door side weather strip 11.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash structure for a motor vehicle, and more particularly to a structure in which a main sash is screwed to an upper end of a partition sash.

[0002]

2. Description of the Related Art An L-shaped bracket is provided at an upper end of a partition sash on a side door of an automobile, and the bracket is fixed to a main sash from above by a countersunk screw.
Some main sashes have a weatherstrip on the upper surface and a seal between the body sash and the body opening.
-43433).

[0003]

By the way, in order to ensure the water-tightness and air-tightness of the weather strip, it is necessary that the back surface of the base portion be in close contact with the upper surface of the main sash. For this reason, in this conventional example, a counterbore is formed in the countersunk screw insertion hole of the main sash, and the head of the countersunk screw is flush with the upper surface of the main sash. On the other hand, when a round screw is used, a counterbore must be provided on the weather strip side in order to avoid interference with the head.

Further, if water is discharged into the parting gap between the weather strip and the glass run at the time of car washing, water may enter the gap between the base portion of the weather strip and the main sash, and may flow out into the vehicle compartment if the amount of penetration is large. There is.

The present invention has been made in view of the above circumstances, and has as its object to provide a sash structure of an automobile which does not require a counterbore to be formed on a sash or a weatherstrip and has no risk of car wash water entering a passenger compartment. Aim.

[0006]

According to the present invention, there is provided a structure in which a mainsash is screwed to an upper end of a partition sash and a weather strip is mounted on an upper surface of the main sash. The weatherstrip of the main sash is formed in a channel portion having a substantially U-shaped cross section to accommodate the head of the screw member.

A flange may be extended outward at each of both ends of the channel portion, and locking portions may be integrally formed at both ends of the weather strip so as to wind the flange.

[0008]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows the inside of a dotted frame B of FIG. In the figure, reference numeral 1 denotes a main sash formed by press-molding a plate material, and has a hollow portion 2 and a glass run locking groove 3. A channel portion 4 having a substantially U-shaped cross section is formed on the upper surface of the main sash 1, and both ends of the channel portion have outwardly extending flanges 5 extending therefrom.

Reference numeral 6 denotes a partition sash, on the upper end of which an L-shaped bracket 7 is provided. A round screw 10 is inserted into the hole 8 of the bracket 7 and the hole 9 of the main sash 1.
Partition sash 6 through the main sash 1
Then, the locking portions 12, 12 of the door side weather strip 11 are engaged with the flange 5 of the channel portion 4, and the door side weather strip 10 is mounted on the channel portion 4. The glass run lock groove 3 of the main sash 1 has a glass run 13 as shown in FIG.
The body side weather strip 15 is in close contact with the side wall of the hollow portion 2 while the engaging portion 14 is engaged. Also, the door side weather strip 11 has its seal lips 11a, 11a in close contact with the vehicle body opening.

In this embodiment, the portion of the main sash 1 on which the door side weather strip 11 is to be crowned is formed in the channel portion 4 having a substantially U-shaped cross section to accommodate the head of the round screw 10. It is not necessary to form a counterbore in the main sash 1 and the door side weather strip 11 to avoid interference with the screw member head.

Further, the flanges 5, 5 of the channel portion 4
Locking portions 12, 1 of the door side weather strip 11
Since the two are engaged, the assembling work is easy and the holding strength is high.

Further, even if water is discharged into the parting gap P between the door side weather strip 11 and the glass run 13 during car washing, water that has entered the channel portion 4 from this gap P passes through the channel portion 4 to form the main sash 1. Since the water is guided to the lower side, even if the amount of intruded water is large, there is no possibility that the water will flow out into the vehicle interior.

[0014]

According to the present invention, since the head of the screw member is housed in the channel portion of the main sash, a counterbore is formed in the main sash or the weather strip to avoid interference with the head of the screw member. You don't have to.

Further, even if water is discharged into the parting gap between the weather strip and the glass run during car washing, the water that has entered the channel from this gap is guided to the lower side of the main sash through the channel, so that the amount of water that has entered Even if the amount is large, there is no possibility that the gas will flow into the vehicle interior.
