Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for preventing a windshield provided in a sillless door of an automobile from being sucked out to the outside of the vehicle body due to negative pressure.

(Prior Art) When a vehicle travels, the front surface receives air pressure, and some portions of the vehicle, such as the side surfaces, are in a negative pressure state. For this reason, there is a problem in that the side doors, especially the window glass, are sucked out by this negative pressure, causing the seal to break between the door and the vehicle body, resulting in wind noise. For this reason, as disclosed in Utility Model Application Publication No. 57-138779, for example, a holder piece is placed on the upper edge of the side opening of the vehicle body to which the door is attached, which restrains the suction movement of the door sash, to solve the above problem. Suggestions are made to address this.

However, in this case, the holder piece must be attached separately, which increases the number of parts and installation man-hours, which is undesirable.Furthermore, since the holder piece protrudes outward, it is not desirable to reduce air resistance, improve appearance, etc. It is also unfavorable in terms of flash surfing.

On the other hand, recently, suspensionless doors are often used, especially in hard-top cars.
In this case as well, measures to prevent the windshield from being drawn out are necessary. In particular, in order to achieve the above-mentioned flash surface, the window glass needs to be placed near the outer surface of the vehicle body, and measures to prevent the windshield from sucking out are even more necessary.

(Purpose of the invention) In view of these circumstances, the present invention has been developed to provide a window that can prevent the window glass from being sucked out of a sillless door with a relatively simple structure, has excellent assembly workability, and can be used as a flat surface. The object of the present invention is to provide a glass suction prevention device.

(Structure of the invention) The windshield suction prevention device of the present invention comprises: a windshield which is movable up and down on a sashless door that covers an opening of the vehicle body so as to open and close; a weather strip that the peripheral edge of the windshield comes into contact with and seals the interior and exterior of the vehicle interior; a mounting base that extends toward the vehicle body and whose inner end is fitted into a retainer member attached to the vehicle body; and a hard member that is fixed to the mounting base and provided outside the vehicle interior to restrict movement of the window glass toward the outside of the vehicle interior. It is composed of a lip part and a seal part which is disposed inward of the vehicle interior from the hard lip part and comes into contact with the peripheral edge of the window glass when the window glass is raised. and a connecting portion that connects the legs, and a core bar having a U-shaped cross section is embedded in the mounting base. When the retainer member is fitted, the leg portion is fitted into the groove, and the leg portion is fitted into the retainer member at a position where the surface of the connecting portion and the surface of the vehicle body are substantially flush with each other, and The fixation to the mounting base is characterized in that the surface of the connecting portion of the mounting base and the surface of the hard lip are substantially flush with each other.

(Effects of the invention) According to the invention, the weather strip is attached to the vehicle body by fitting the mounting base between the retainer member and the vehicle body from outside the vehicle body. It is very easy to install and has good workability. Furthermore, when the windshield is closed and the peripheral edge of the windshield is brought into contact with the seal, the hard lip is placed outward from the seal. This prevents the windshield from moving, prevents the windshield from being sucked out, prevents seal breakage, and eliminates wind noise. Further, by arranging this hard lip portion along the outer surface of the vehicle body, a flash surface can be achieved.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 2 is a front view of an automobile 1 having a windshield suction prevention device according to the present invention. A weather door 2 having a windshield 3 that can be raised and lowered up and down is installed to cover the side opening of the vehicle body, and when the windshield 3 is raised, it comes into contact with the upper and front edges of the windshield 3 to seal the inside and outside of the vehicle interior. A strip 10 is attached to the vehicle body.

FIG. 1 is a cross-sectional view of this portion along arrow A-A. The ends of the roof panel 5 and the ends of the roof rails 6 are joined to form a roof side closed cross section, and a retainer extends in the front and rear of the vehicle body on the obliquely downwardly facing flat part 5a of the roof panel 5 forming this closed cross section. The inner end of the member 4 is fixed by sput welding or screwing. This retainer member 4 has a predetermined interval between a flat part 5a of the roof panel 5 and a parallel flat stepped part 5b, extends outward from the vehicle body, and has a weather strip within this predetermined interval. The leg portion 11a of the mounting base 11 of No. 10 is inserted into the leg portion 11a.

The weather strip 10 includes a leg portion 11a that is inserted within the predetermined interval, and a base portion 1 that is integrated with the leg portion 11a and wraps around the retainer member.
1b, and this mounting base 1.
a hard lip part 12 that is molded integrally with the roof panel 1 and extends along the outer surface of the roof panel 5; and a seal support that is molded integrally with the mounting base 11 and is arranged parallel to the hard lip part 12 on the inside of the vehicle body from the hard lip part 12. 14, and a seal portion 13 which is disposed between the hard lip portion 12 and the seal support portion 14 and comes into contact with the peripheral edge of the window glass 3 when it is raised, and has a reinforcing core bar 15. A seal part 13 made of soft rubber (foamed rubber) is integrally formed by double extrusion molding on a mounting base 11, a hard lip part 12, and a seal support part 14 which are integrally molded from hard rubber or soft plastic. For this reason, the weather strip 10 is designed such that the leg portion 11a of the mounting base 11 is inserted between the retainer member 4 and the planar stepped portion 5b, and the retainer member 4 is sandwiched between the leg portion 11a and the base portion 11b. It can be attached to the car body by simply doing so, making it extremely easy to install. Furthermore, when the roof panel 5 is attached to the vehicle body in this manner, the hard lip portion 12 extends along the outer surface of the vehicle body, so that the vehicle body can be made into a flat surface.

On the other hand, the hard lip portion 1 on which the seal portion 13 is arranged
When the window glass 3 is raised, the upper edge of the window glass 3 is inserted between the seal support part 14 and the seal support part 14, and the upper edge of the window glass 3 comes into contact with the seal part 13, sealing the inside and outside of the vehicle interior. . As shown in the figure, when the window glass 3 is in contact with the seal part 13, the window glass 3 moves in the direction of arrow B in response to the opening and closing of the door 2, and can be opened and closed. Since the suction direction of the window glass 3 due to the negative pressure is perpendicular to the glass surface as shown by arrow C, the movement of the window glass 3 in the suction direction is prevented by the hard lip portion 12. Therefore, the windshield 3 is prevented from being sucked out, the seal is not broken, and the generation of wind noise in this area can be suppressed. In this embodiment, the seal portion 1 is provided between the seal support portion 14 made of hard rubber or the like and the hard lip portion 12.
3 is arranged, so when the window glass 3 comes into contact with the sealing part 13, the supporting part 14 and the lip part 1
2 to increase the sealing pressure at the abutting portion.

In addition, in this figure, the window glass 3' indicated by a two-dot chain line indicates the position when the window glass is raised without the weather strip 10, and this is actually the position of the window glass 3' shown in the seal portion 13 of the weather strip 10. They come into contact with each other and are pushed outward from the vehicle body, reaching the position shown by the solid line 3.

FIG. 3 is a cross-sectional view showing a different embodiment of the present invention, and this figure also shows a cross section taken along the arrow A--A in FIG. Note that parts that are the same as those in FIG. 2 are given the same numbers and their explanations will be omitted.

The retainer member 4, whose inner end is fixed to the flat part 5a of the roof panel 5, extends outward from the vehicle body with a predetermined distance from the flat stepped part of the roof panel 5, as in the case of FIG. However, this predetermined interval is set wider than the interval in the case of FIG. Therefore, when the weather strip 10 is attached from the outside of the vehicle body with the retainer member 4 sandwiched between the leg portion 11a and the base portion 11b forming the mounting base 11 of the weather strip 10, the leg portion 11
A certain distance still remains between the a-plane step portions 5b. Within this fixed interval, the leg 16 of the drip molding 16
b is inserted and the drip molding 16 is attached. Further, a stepped portion 5c for receiving the outer side portion 9a of the drip molding 16 is formed at the lower part of the outer surface of the roof panel 5, and the leg portion 9b is inserted between the leg portion 11a of the mounting base 11 and the flat stepped portion. When the outside part 9a of the drip molding 16 is
It is designed to fit inside and create a flat surface surface on the outside of the car body.

As described above, according to the present invention, the windshield can be prevented from being sucked out by the weather strip, thereby preventing the generation of wind noise, and the installation work of the weather strip is easy. It is also possible to create a TsushiyusurfS.
