Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a roof ventilation system for an automobile that is placed on the roof and ventilates the interior of the vehicle.

[Problems that conventional technology and ideas try to solve]

Ventilators of this type are well known in various configurations as intake or exhaust types, but they only perform their original function of ventilation. on the other hand,
An opening at the rear of an automobile body is usually equipped with a rear glass, but fixing around the opening relies exclusively on special fixing means using weather strips or moldings. When using such a weather strip, it is necessary to have a shape that includes a recess that engages with the body around the glass and the opening.
Further, when a molding is used, a spacer and a retainer for holding down the glass are required inside the molding, and the molding itself must be fixed to the body. That is, all of them have a weather strip or molding structure around the entire circumference of Liliglass, which requires a corresponding amount of cost.

In view of this point, it is an object of the present invention to provide an automobile roof ventilation system that also has a function of suppressing the rear window.

[Means for solving problems]

In order to achieve this objective, the present invention forms the bottom surface of the roof ventilation device to correspond to the shape of the surface extending from the rear part of the roof to the upper end of the rear glass attached to the body opening for the rear glass, and also The rear portion of the bottom surface was screwed to the upper peripheral body portion of the body opening through a screw through hole formed in the upper end of the rear glass.

[Effect]

The roof ventilation device performs a normal vehicle interior ventilation function on the roof, and the rear portion of the bottom portion of the device is fastened to hold the upper end of the rear glass in the upper peripheral body portion of the body opening to hold the rear glass in a predetermined position.

[Example of idea]

In FIG. 1, reference numeral 10 denotes a roof ventilation device consisting of a duct, which has an exhaust opening 11 at its rear, and this duct is formed in a shape corresponding to the shape extending from the rear of the roof 1 of the automobile to the rear of the body 1b. ,
A curved portion 12 is provided at the rear. Inside, there are vents 13 symmetrically on both sides into the passenger compartment, and exhaust guides 14 to 1 that guide the exhaust air while avoiding rainwater intrusion.
6. A drain hole 17 and a screw through hole 18 are provided. Of the screw through holes 18, nuts 18a are installed in two on the front side, and bolts 18b are installed in the two on the rear side.

On the other hand, the rear panel 1a of the roof 1 is provided with corresponding screw through holes 21 and ventilation holes 22. Further, as shown in FIG. 2, a rear header 1c is joined to the roof rear panel 1a, and furthermore, one end of the rear header 1c supports the molded ceiling plate 2, and the other end of the rear glass 4 is attached to the body opening 3 at the rear of the body. A glass retainer 1d extending toward the inner surface of the body opening 3 and having a width corresponding to the width of the body opening 3 is bonded to the glass retainer 1d. Therefore, the bottom surface of the above-mentioned curved portion 12 is connected to the glass retainer 1 which becomes the body portion around the upper part of the body opening 3.
It is formed in a surface shape that follows the rear glass 4 that is in contact with d. The molded ceiling plate 2 is provided with an indoor ventilation opening 5 having a plurality of slits.

When assembling the roof ventilation system 10 and the rear glass 4, the rear glass 4 is fixed to the body recess 7 around the body opening 3 using an adhesive 8. The periphery 4a of this rear glass is subjected to a black ceramic surface treatment to hide the adhesive portion, and a screw through hole 4b corresponding to the screw through hole 18 is formed in the upper part. Next, the roof ventilation system 10 is placed at a predetermined position at the rear of the roof 1 (the position indicated by the two-dot chain line in FIG. 1a) via the seal 25. and,
As shown in FIG. 2, the two screw holes 18 on the front side are screwed with bolts 18e from inside the vehicle interior, and the two screws on the rear side are screwed through the screw through holes 4b of the rear glass 4 with nuts 18f from the opening 11 through spacers 18g. Stop. As a result, the roof ventilation system 10
is mounted on the roof 1, and the rear glass 4 is pushed into the body recess 7 by the bolt 18b, securely held by the bolt itself, and also pushed in through the seal 25 at the rear end of the bottom surface. The cover 9 is fixed to the glass retainer 1d for the sake of appearance.

As shown in FIG. 3, around the rear glass 4, a pad 24 is engaged with the concave part to hide the gap with the body concave part 7, so that when it is attached to the body opening 3, the outer circumferential inner surface of the pad 24 is upward and downward. It is also conceivable to have it rest on the left and right bodies. In this case, since the pad 24 does not need to be involved in holding down the rear glass 4, it can be simply attached to the rear glass 4. Further, as shown in FIG. 4, L-shaped stoppers 26 are provided on the body surface at the lower end of the body opening 3, for example, at two locations in the left and right directions, in order to facilitate attachment of the rear glass 4 to the body opening 3. It is also conceivable to have it locked. In addition, various modifications can be made to the bottom structure of the roof ventilation system 10 that constitutes the restraint for the rear glass 4 and the corresponding structure of the rear part of the body. The invention also applies to air-supply roof ventilation systems or to the maintenance of an approximately vertical rear window, in that the rear part of the roof ventilation system is provided with a corresponding shape.

[Effect of idea]

As described above, according to the present invention, in an automobile equipped with a roof ventilation device, the rear window can be held down to the body at the rear bottom surface thereof, and a dedicated holding structure is not required, which is advantageous in terms of cost.
Moreover, since the bottom surface is used, the appearance is not spoiled. The design is also new.
