Description

[Detailed Description of the Invention] The present invention relates to a stopper for stopping a vehicle door glass from moving outward during high-speed driving.

Conventionally, in a hard-top vehicle 1 as shown in FIG. 1, the door 2 is a so-called sashless door without a sash. And the door 2
When the door glass 3 is closed, the vehicle body opening 4 for attaching the door glass 3 and the door 2 is opened.
The seal between the door and door is provided by a door weather strip 5 as shown in FIG. This door weather strip 5 is fitted into a retainer 6 having a substantially U-shaped cross section attached to the vehicle body opening 4, and includes a hollow main lip 5a and a main lip 5a.
A hollow outer lip 5b is provided which projects outward from the upper end of the door glass 3 when the door glass 3 comes into contact with the door glass. By the way, the tip of this outer lip 5b hangs downward due to the pressing force of the door glass 3, and this prevents the upper end of the door glass 3 from slightly protruding when the door glass 3 is sucked outward during high-speed driving. It is designed to prevent this. By preventing the door glass 3 from popping out in this manner, it is possible to prevent a seal failure occurring at the upper end of the door glass 3 and wind noise caused by this seal failure during driving. However, as mentioned above, prevention of the door glass 3 from flying out is achieved only by the outer lip 5b, but in addition to the outer lip 5b, a stopper that actively prevents the door glass 3 from flying out is used. You can achieve your goals more reliably.

In view of the conventional situation, the present invention provides a door glass stopper on the door weather strip that can reliably prevent the door glass from being sucked out during driving without causing any hindrance when the door is opened or closed. This is what I did.

That is, the stopper of the present invention has one end formed with a fixed part fixed to the retainer, the other end covered approximately along the outer shape of the outer lip, and the tip of the stopper formed with the inner part of the outer lip. A covering part is formed with a bent part whose side faces face upward from below and whose tip is located at the base of the outer lip, and is approximately horizontally parallel to the contact part between the bent part of the covering part and the door glass. A bent portion is formed in the midsection at the same position, and is located below the direction of the door glass pop-out load during driving that acts on the contact portion between the bent portion and the door glass, and
At least the covering portion is made of a highly rigid member.

With the above-described structure, in the vehicle door glass stopper of the present invention, when the door glass interferes with the bent part when opening/closing the door, the bent part rotates upward about the bent part. , allowing passage through the door glass. By the way, when the door glass passes through with the rotation of this bent part, the outer lip is deformed by the tip of the bent part, but this deformation of the outer lip is easily achieved by the large load applied when opening and closing the door. Ru.

On the other hand, when a pop-out load is applied to the door glass during driving, the bent portion is located on the lower side with respect to the direction of the pop-out load that acts on the contact portion between the door glass and the bent portion. The bent portion is about to be rotated upward around the bent portion,
The tip of the bent portion is brought into contact with the base of the outer lip. However, since the bent portion is provided in the midsection at approximately the same position in the horizontal direction as the contact portion between the bent portion of the covering portion and the door glass, most of the door glass protrusion load is applied to the bent portion. It acts to bend in the direction of the bend. However,
Since the covering portion is formed of a material with high rigidity, the bending portion also has high rigidity, and the pop-out load is supported by the bending portion with high rigidity, thereby preventing the door glass from moving outward. Ru.

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

In FIG. 3, reference numeral 6 denotes a retainer attached to the periphery of an opening in the vehicle body (not shown). There is.

Reference numeral 5 denotes a door weather strip that is fitted and attached to the retainer 6. The door weather strip 5 has a base portion 5c fitted into and engaged with the bulging portion 6a of the retainer 6, and the base portion 5c A hollow main lip 5a is protruded from the main lip 5a, and the upper end of the door glass 3 comes into contact with the main lip 5a, thereby creating a seal between the door glass 3 and the vehicle body opening.

Further, an outer lip 5b is formed on the outer side of the main lip 5a, and projects outward and downward from the upper end of the door glass 3 when the door glass 3 is closed. 3 is designed to prevent it from flying outward due to negative pressure generated during high-speed driving.

In this manner, by preventing the door glass 3 from popping out by the outer lip 5b, it is possible to prevent seal failures and wind noises caused by the seal failures during driving.

Here, as shown in FIG. 4, the outer lip 5b has a fixing part 11 fixed to the retainer 6 at one end (upper end in the figure), and a fixing part 11 fixed to the retainer 6 at the other end. A stopper 10 is provided with a covering portion 12 that is covered substantially along the shape.

Further, the entire stopper 10 from the fixing part 11 to the covering part 12 is made of a highly rigid member such as a hard synthetic resin.

The fixing portion 11 is formed into a bifurcated clip shape so as to sandwich the outer end of the retainer 6.

Further, a bent portion 12a is provided at the tip of the covering portion 12, and the bending portion 12a extends from the bottom to the top of the inside (left side in the figure) side of the vehicle interior, and the tip thereof is located at the base of the outer lip 5b. 12, the bent portion 1 is located in the midsection at approximately the same position in the horizontal direction as the contact portion between the bent portion 12a and the door glass 3.
3 is formed. This bending part 13 is constructed by forming a groove 13a inside the covering part 12 to make it a thin part, so that the tip of the covering part 12 can be easily bent in the direction of the outer lip 5b.

The bent portion 13 may be formed by connecting the fixed portion 11 and the distal end of the covering portion 12 with a hinge 13b as shown in FIG. 5, and the hinge 13b may be used as the bent portion 13. The fixed part 11 and the covering part 12 may be connected by an elastic member 13c made of soft rubber or synthetic resin, and this elastic member 13c may be used as the bent part 13.

On the other hand, when opening and closing the door with the door glass 3 raised, the upper end of the door glass 3 normally draws a trajectory P as shown in FIG. That is, when closing the door, the upper end of the door glass 3 is lifted upwards just before it is completely closed, and when opening the door, it moves in the opposite direction along substantially the same trajectory P as when closing the door. I'm starting to do that.

Further, when the door is closed and the upper end of the door glass 3 is sandwiched between the main lip 5a and the outer lip 5b, the tip of the bent portion 12a contacts and is locked to the upper end of the door glass 3. It's getting old. The bent portion 13 is disposed below the direction of the door glass protrusion load F during driving which acts on the contact portion between the bent portion 12a and the door glass 3.

Therefore, in the stopper 10 of the present invention, when opening and closing the door with the door glass 3 raised, the inside side of the bent portion 12a of the covering portion 12 is arranged under the outer lip 5b. The upper end of the door glass 3 is located below the trajectory P, and the upper end of the door glass 3 interferes with the bent portion 12a. However, when the door glass 3 interferes with the bent portion 12a during opening and closing of the door, the bent portion 12a moves toward the outer lip 5b (upward) around the bent portion 13 provided in the midsection of the covering portion 12. It rotates to allow the door glass 3 to pass through. At this time,
Although the tip of the bent portion 12a presses the outer lip 5b, the outer lip 5b is easily changed by a large force when opening and closing the door, so that the door glass 3 can pass through.

On the other hand, when driving with the door glass 3 raised, a pop-out load F acts on the contact area between the door glass 3 and the bent portion 12a due to the negative pressure generated during high-speed driving. Since the bent portion 13 is located on the lower side with respect to the orientation direction of the pop-out load F, the bent portion 12a tends to be rotated in the direction of the outer lip 5b around the bent portion 13 in the same way as when opening and closing the door described above. The tip of the bent portion 12a is brought into contact with the base portion of the outer lip 5b, which has relatively high rigidity. At this time, since the bent portion 13 is provided in the midsection at approximately the same position in the horizontal direction as the contact portion between the bent portion 12a of the covering portion 12 and the door glass 3, most of the pop-out load F of the door glass 3 is absorbed by the bent portion 13. acts to bend the bent portion 12a in the direction of the bent portion 13. However, since the stopper 10 is made of a member with high rigidity, the bending portion 12a also has high rigidity, and the pop-out load F is supported by the bending portion 12a with high rigidity. Coupled with the fact that the tip of the curved portion 12a comes into contact with the base of the outer lip 5b, outward movement of the door glass 3 is reliably prevented.

Therefore, the effect of preventing the outward movement of the door glass 3 only by the outer lip 5b is greatly improved, and seal failures, wind noise, etc. that occur when the door glass 3 moves are reliably prevented.

The stoppers 10 are formed to have an appropriate length and are bonded to a plurality of optimal locations to prevent the door glass 3 from moving.

As explained above, the present invention allows the bending portion of the highly rigid stopper to support the pop-out load that acts on the door glass during driving, thereby reliably preventing the door glass from being sucked out.

Additionally, even if the top edge of the door glass interferes with the stopper when the door is opened and closed, the large force applied when opening and closing the door deforms the outer lip and rotates the bent part, allowing the door glass to pass through. .

Therefore, the vehicle door glass stopper of the present invention is advantageous in that it allows the door to be opened and closed while reliably preventing the door glass from moving outward during driving, thereby preventing seal failure and wind noise. It has a great effect.
