Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass side weather strip which is attached to one glass and elastically contacts one of the other glasses to seal between the two glasses.

[0002]

2. Description of the Related Art Conventionally, a glass-side weather strip which is attached to one glass and elastically contacts one of the other glasses and seals between the two glasses is, for example, a front glass and a rear glass of a car having no center pillar. It is used to seal with the side glass. A glass side weatherstrip is attached to the rear side glass to make elastic contact with the front side glass, thereby sealing between the two glasses.

As the glass-side weather strip used for this, one having a cross-sectional shape shown in FIGS. 6A and 7A is generally used. In the glass side weather strip W1 shown in FIG. 6A, a base 30 attached to the front end of the rear side glass 2, an extension 40 extending from the base 30 to the vehicle interior side of the front side glass 1, And a lip portion 50 that extends from the front end of the extension portion 40 to the outside of the vehicle cabin. In the sealed state in which the glass side weather strip W1 elastically contacts the front side glass 1,
As shown in FIG. 6B, the distal end portion 80 of the lip portion 50 is configured to elastically contact the front glass 1. In addition,
Reference numerals 60 and 70 in FIGS. 6A and 6B denote core metals disposed in the glass-side weather strip W1. In the glass side weather strip W1 shown in FIG. 6, since the front end portion 80 is in elastic contact with the front side glass 1 as described above, as shown in FIG. When receiving a water pressure P by a high-pressure car wash or the like in a state of sealing between the glass 2, the pressure is applied between the extending portion 40 and the lip portion 50, and as a result, the elasticity between the front glass 1 and the lip portion 50 is generated. Since the contact force is strengthened, there is an advantage that it is difficult for water to enter the vehicle interior even when receiving such a water pressure P. However, due to variations in the relative positions of the front glass 1 and the rear glass 2 due to an assembling error or the like, the leading end 80 of the lip 50
When the rear end portion of the front glass 1 is located forward (left side in the figure), the water pressure P is applied to the outer side of the front end portion 80 (downward in the figure), and the lip portion 50 is located in the vehicle interior side (see FIG. (Upward), the seal may be broken such that the lip portion 50 comes off the front glass 1, and water may enter the vehicle interior.

In the glass side weather strip W2 shown in FIG. 7 (a), a base 31 attached to the front end of the rear glass 2 and an extension extending from the base 31 to the inside of the front glass 1 in the vehicle compartment. It has an installation portion 41 and a lip portion 51 that extends from the front end of the extension portion 41 to the outside of the vehicle compartment and extends to the base portion 31. In the sealed state in which the glass-side weather strip W2 elastically contacts the front-side glass 1, the structure becomes as shown in FIG. 7B, and the lip portion 51 elastically contacts the front-side glass 1 in a wide range, that is, a surface sealing structure. ing. Reference numerals 61 and 71 in FIGS. 7A and 7B denote a core metal provided in the glass-side weather strip W2. Since the glass side weather strip W2 shown in FIG. 7 has the surface sealing structure as described above, even if the front side glass 1 is largely displaced in the forward direction as compared with the glass side weather strip W1 shown in FIG. It has the advantage of being sealable. However, in the sealed state shown in FIG. 7B, when the water pressure P is applied by the high-pressure car wash or the like, the pressure is applied between the front glass 1 and the lip portion 51.
Is bent to form a gap, and water easily enters the vehicle interior.

[0005] Assuming that these two glass-side weather strip structures are combined, an actual H6-53244 has an h-shaped base fitted to the rear glass, and extends from the base to the interior side of the front glass. A glass side weather strip having an extended portion to be extended, a small lip folded back from a front end of the extended portion, and a large arc-shaped large lip branching from a base of the small lip and extending toward a base is disclosed.
According to this, when receiving the water pressure P, the large lip bends and a gap is formed between the large lip and the front glass, but the small lip is in elastic contact with the front glass, so that water flowing into the vehicle cabin is prevented. Intrusion can be prevented.

[Problems to be solved by the invention]

However, the glass-side weather strip disclosed in Japanese Utility Model Laid-Open Publication No. 6-53244 has a complicated cross-sectional shape, that is, unless two lips, a small lip and a large lip, are extended from the front end of the extended portion. Because it does not become
There is a problem that the thickness increases. For this reason, in the state of being in elastic contact with the front glass, it protrudes to the vehicle interior side more than the conventional glass weather strips W1 and W2 shown in FIGS.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems. According to the first aspect of the present invention, there is provided a glass-side weatherstrip which is one of two adjacent glass panels for partitioning between indoor and outdoor. A base portion attached to the end portion, an extension portion extending from the base portion to the indoor side of the other glass, a second portion extending back from the extension portion to the outside of the glass, and a tip portion elastically contacting the other glass. It is characterized in that it has one lip portion and a second lip portion that is folded back from the extending portion above the first lip portion to the outside of the room to extend to the base portion and elastically contacts the other glass.

According to this, the tip of the first lip resiliently contacts the other glass to reliably seal the inside and outside of the room. The second lip portion above the first lip portion has its outdoor surface elastically contacting the other glass to seal between the two glasses.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a convertible car. A regulator device 12 is attached to a door 16 which is openably and closably attached to a side portion of the vehicle, and a front glass 1 is attached to the regulator device 12 via a connecting portion 14. The front glass 1 is shown in FIG. It can be moved up and down between a closed state in which the interior and exterior of the vehicle are partitioned and an open state stored inside the door 16. The regulator device 13 attached to the vehicle body behind the opening of the door 16
The rear-side glass 2 is attached to the vehicle through a connecting portion 15, and the rear-side glass 2 is also movable up and down between a closed state that partitions the inside and outside of the vehicle compartment shown in FIG. 1 and an open state that is stored inside the vehicle body. ing. The front glass 1 and the rear glass 2 are located adjacent to each other. A glass-side weather strip GW is attached to the front end of the rear-side glass 2 and moves up and down together with the rear-side glass 2. When the rear-side glass 2 is closed, the rear-side glass 2 can be elastically contacted with the front-side glass 1. Is stored inside the vehicle body together with the rear glass 2. A foldable vinyl hood device 18 forming the roof of the passenger compartment is attached to the vehicle body at its rear end, and the hood device 18 is closed and the hood device 18 is closed as shown in FIG. To open and close with an open state stored in a storage unit (not shown) behind the vehicle compartment.
A pillar weather strip PW is attached to a pillar 17 located in the front of the passenger compartment, and in a state where the front glass 1 is raised and the door 16 is closed, the pillar weather strip PW elastically contacts the front glass 1 and the pillar 1
7 and the front glass 1 are sealed. Further, the side weather strip SW is attached to the hood device 18, and the hood device 18 and the respective glasses 1 and 2 are closed in a state where the door 16 is closed and the front glass 1 and the rear glass 2 are raised and closed. Seal between

Next, the detailed structure of the glass-side weather strip GW is shown in FIGS. FIG. 2 is a perspective view of the entire glass-side weather strip GW. The glass-side weather strip GW is fitted to the rear-side glass 2 at the base 3 and is bonded thereto. An extended portion 4 is provided from the base portion 3 and extends in the vehicle interior direction of the front glass 1 and in the vehicle forward direction. A first lip portion 5a that is folded from the front end of the extended portion 4 to the vehicle exterior side has a range I. (FIG. 3A). In addition, 6 and 7 are metal cores arranged in the glass side weather strip GW.

Further, the glass side weather strip GW in the upper portion J located above the range I is a sectional view (B-
As shown in FIG. 4A, a second lip portion 5 b is provided, which is folded from the front end of the extension portion 4 to the outside of the vehicle compartment and extends to the base 3. A space 10 is formed between the second lip portion 5b and the extension portion 4, and a drain hole 11 is formed at a lower end thereof. The shape of the connecting portion (upper end of the range I) between the first lip portion 5a and the second lip portion 5b is such that the second lip portion 5b is tapered as shown in FIG. And the space 10 disappears. At this time, the first lip portion 5a is gradually formed.

Next, the operation of this embodiment will be described. First, the hood device 18, the front glass 1, the rear glass 2
1 is closed from the state in which all of them are opened, the hood device 18 is pulled out from the storage portion at the rear of the passenger compartment and fixed to the state in FIG. 1, and then the regulator device 13 is operated. When the rear glass 2 is lifted up and closed, the upper end of the glass-side weather strip GW rises as the rear glass 2 rises.
W and upper part J of glass side weather strip GW
The side weatherstrip SW is bent by the extension portion 4 of the above, and both weatherstrips GW and SW are brought into close contact with each other. As a result, the glass-side weather strip GW and the rear-side glass 2 are arranged outside the cabin of the side weather strip SW. When the door 16 is thereafter closed and the front glass 1 is raised and closed, the glass weather strip GW and the side weather strip SW bend, and the front glass 1 is disposed outside the cabin of the side weather strip SW. Here, the rear end of the front glass 1 resiliently contacts the front end portion 8 of the first lip portion 5a in the range I, and has a shape shown in FIG. In the upper part J, the upper part of the rear end of the front glass 1 is the second lip part 5.
As shown in FIG. 4B, the space 10 is reduced by elastic contact with the vehicle exterior surface 9 of FIG.

Now, a description will be given below of a case where a water pressure P is applied by a high-pressure car wash or the like in the above-described state (FIG. 1). In the range I, water penetrates between the extending portion 4 and the first lip portion 5a, and strongly presses the first lip portion 5a against the front glass 1 by the water pressure P. When the upper portion J receives the water pressure P, the second lip portion 5b and the extending portion 4 try to move toward the vehicle interior by the same pressure, but are supported by the reaction force of the side weather strip SW. That is, since the portion of the range I has the structure having the first lip portion 5a, it is possible to reliably prevent water from entering the vehicle interior. Also,
The upper portion J receives the force supported by the side weather strip SW to prevent water from entering. Furthermore, in the upper portion J where the relative position between the front glass 1 and the rear glass 2 is large, even if the front glass 1 is largely displaced in the forward direction, the second lip portion 5b is kept on the front glass 1.
And can seal the space between the front glass 1 and the rear glass 2 to prevent water from entering the passenger compartment due to the water pressure P of a high-pressure car wash and the like, and to disperse the relative position between the two glasses. Can prevent the seal from breaking.

Further, as shown in FIGS. 3 (a) and 4 (a), the first and second lip portions 5a and 5b which are in elastic contact with the front glass 1 have a simple shape, so that the glass weather strip is provided. The GW can be made thinner, and the protrusion toward the vehicle cabin side can be made smaller to improve the appearance.

In the above-described embodiment, an open car is described as an embodiment of the present invention. However, the present invention is not limited to this, and a pillarless hardtop car or a front door glass mainly includes a triangular window. A car divided into two parts of the window,
The present invention can be applied to all glass-side weather strips that directly seal glass and glass, such as a car in which a rear hatch is divided and opened to the left and right, a train window, a building window, and the like.

Although the glass weather strip GW is attached to the front end of the rear glass 2, it may be attached to the front glass to make elastic contact with the rear glass.

Further, the entire range I of the glass-side weather strip GW is shown as the first lip portion 5a whose front end portion 8 is elastically provided on the front glass 1, but a part of the range I, for example, a belt line. The overlapping part is the second lip part 5
A lip of another structure such as b may be used.

In addition, although the second lip 5b is connected to the base 3, the second lip 5b may be extended to the base 3 and may not be connected to the base 3.

[0019]

As described above, according to the glass side weather strip according to the present invention, when the water pressure of the high-pressure car wash is applied between the first lip portion and the extension portion, the first lip portion is caused by the water pressure. It is strongly pressed against the other glass to improve the sealing effect. In addition, since a second lip portion extending from the tip of the extending portion to the base portion is provided at an upper portion of the glass where relative displacement between the two glasses is likely to be large, the above-mentioned displacement can be absorbed and sealed securely. is there. In addition, since the first and second lip portions resiliently contacting the other glass have a simple shape, they can be made less protruding toward the indoor side to improve the appearance.
