Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing structure for a mounting portion of a weather strip retainer provided around a door of an automobile, particularly a hard top type vehicle.

[0002]

2. Description of the Related Art FIGS. 3 to 5 show a structure around a door of a conventional hard top type vehicle, in which a body side weather strip 10 (hereinafter, simply referred to as a weather strip) is provided at a substantially upper peripheral edge of a vehicle body opening 1. The weather strip 10 is attached to the door window panel 13
The periphery of the vehicle is closely contacted to seal the inside and outside of the vehicle.

The weather strip 10 is fitted and held on a retainer 2 which is formed by superposing an upper wall 4 of a holder portion 3 having a substantially channel-shaped cross section at the peripheral edge of a vehicle body opening 1 and fastening and fixing the same with screws 15 or the like. A hollow seal lip 11 with which the peripheral edge of the door window panel 13 is in close contact,
A decorative lip 12 is formed integrally with the welt 14 that decorates the vehicle body opening-side peripheral edge of the vehicle body opening portion 1 so that the tip portion is in close contact with and hides the portion where the retainer 2 is disposed.

The retainer 2 has a side wall 5 of the holder portion 3.
Followed by the inner flare portion 6 and the outer flare portion 7
And a glass holder 8 provided with an end rubber 8a at the end of the flare portion 7 on the outer side. The glass holder 8 extends in the front-rear direction. The vibration of the panel 13 and the suction phenomenon of the door window panel 13 to the outside of the vehicle are prevented.

A drip molding 9 having an end rubber 9a at the end is joined to the flare portion 7 on the outer side in the front-rear direction, and the dart molding 9 is used to part the retainer 2 and the roof panel 16. I try to cover up.

Then, a compression type sealing material 17, which is generally called an EPTSEAL, is arranged on the shoulder portion 4a on the vehicle outer side of the upper wall 4 of the holder portion 3 with a double-sided adhesive tape 18, and the sealing material is placed. 17 is compressed between the shoulder portion 4a and the peripheral edge portion 1a of the vehicle body opening portion 1 to seal the mounting portion of the retainer 2.

This similar structure is, for example, in Japanese Utility Model Laid-Open No. 63-58.
No. 023 publication.

[0008]

The sealing material 17 is long and is peeled off from the release paper (not shown) of the double-sided tape 18 attached to one side surface thereof, and is gradually pushed from the front end side or the rear end side of the shoulder portion 4a. Since it is pasted with, it takes a lot of man-hours and is disadvantageous in terms of cost.

Further, as described above, since the long sealing material 17 is pasted on the shoulder portion 4a from the end side by hand, the sealing material 17 is likely to be wavy, protruding, or stretched.
Finally, the sealing material 17 may be excessively protruded from the end portion of the shoulder portion 4a, or conversely, the length may be insufficient, so that it is difficult to stably and properly adhere the sealing material 17 and the sealing performance may be deteriorated. There is.

Further, since the sealing material 17 is adhered to the shoulder portion 4a with the double-sided tape 18, the sealing material 17 is liable to be peeled off due to a catch or the like when the retainer 2 is carried out or carried in, and the positional deviation is likely to occur. If the retainer 2 is assembled to the vehicle body side without noticing it, there is a problem that a seal failure occurs.

Therefore, the present invention provides a sealing structure for a weatherstrip retainer mounting portion, which can reduce the cost by eliminating the work of bonding the sealing material and can further improve the sealing performance.

[0012]

According to a first aspect of the present invention, a retainer is formed by superposing and fastening and fixing an upper wall of a holder portion having a substantially channel-shaped cross section at an opening edge portion of a vehicle body. In a structure in which a weather strip in close contact with the above is fitted and held, a sealing member is provided at an appropriate height from a shoulder portion on the vehicle outer side of the holder upper wall to an upper portion of the side wall, and further outside the side wall. It is characterized in that the peripheral surface on the retainer center side of the sealing member is formed as an inclined surface having an appropriate inclination angle to the outside of the vehicle while being protruded and integrally molded.

A second aspect of the present invention is characterized in that the seal member according to the first aspect is formed into a hollow lip shape having a substantially semicircular cross section.

According to a third aspect of the present invention, the seal member according to the second aspect is provided with a slit communicating with the hollow portion on an inclined surface of a portion of the sealing member which is disposed at least at the curved portion of the opening edge of the vehicle body. It is characterized by that.

[0015]

According to the present invention, since the seal member is integrally formed with the shoulder portion on the vehicle outer side of the upper wall of the holder portion of the retainer, the conventional sticking operation of the seal material is unnecessary, and the cost can be obtained advantageously. Of course, the seal member is integrally molded from the shoulder portion of the holder portion to the upper portion of the side wall so as to protrude beyond the side wall to the vehicle outer side, and the peripheral surface on the retainer center side is inclined to the vehicle outer side at an appropriate inclination angle. Since the retainer is fastened and fixed to the opening edge of the vehicle body, when the seal member is compressed between the shoulder portion and the opening edge portion of the vehicle body, the sealing member protrudes to the outside of the vehicle. Due to the compression deformation of the seal member and the protrusion to the outside of the vehicle, the variation in the seal gap between the vehicle body opening edge portion and the shoulder portion is absorbed and the gap between the vehicle body opening edge portion and the shoulder portion tends to be absorbed. A substantially constant seal reaction force in the front-back direction Interposed it, it is possible to improve the sealability of the retainer mounting portion.

Further, since the seal member is formed integrally with the shoulder portion of the holder, even if the seal member is caught in the retainer during carry-out and carry-in, the seal member does not come off from the retainer and a stable mounting state is maintained. As a result, it is possible to prevent defective sealing when the retainer is assembled to the vehicle body.

According to the second aspect, since the seal member is formed in the shape of a hollow lip having a substantially semicircular cross section, when the retainer is fastened and fixed to the opening edge of the vehicle body, the seal member tends to protrude to the outside of the vehicle. The property is promoted, and the variation in the seal gap between the vehicle body opening edge portion and the shoulder portion can be absorbed more satisfactorily.

According to the third aspect of the invention, since a slit communicating with the hollow portion is formed on the inclined surface forming the peripheral surface of the hollow lip-shaped seal member on the retainer center side, the curved portion of the vehicle body opening edge portion is formed. In this case, the seal member can be flexibly deformed to the outside of the vehicle, and the conformability of the shape of the seal member can be improved in the front-rear direction of the opening edge portion of the vehicle body to improve the sealability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings by assigning the same reference numerals to the same parts as those in the conventional structure.

In FIGS. 1 to 3, a retainer 2 is superposed on the peripheral wall of the upper half of the vehicle body opening 1, and an upper wall 4 of a holder portion 3 having a substantially channel-shaped cross section is superposed and fastened by screws 15 or the like. The retainer 2 is fitted and held with a weather strip 10 that closely contacts the door window panel 13 and seals the inside and outside of the vehicle.

A glass holder 8 for holding a door window panel 13 is provided in the flare portion 7 on the outer side of the retainer 2 so as to extend along the front-rear direction, and the glass holder 8 vibrates the door window panel 13 when the vehicle is running. Then, the phenomenon of sucking out the door window panel 13 to the outside of the vehicle is prevented.

Further, a drip molding 9 is joined to the flare portion 7 on the outer side in the front-rear direction so that the parting portion of the retainer 2 and the roof panel 16 is concealed by the drip molding 9.

The upper wall 4 of the holder portion 3 of the retainer 2 is made of an elastic material such as vinyl chloride resin having excellent flexibility and weather resistance, from the shoulder portion 4a on the vehicle exterior side to the upper portion of the side wall 5. The sealing member 21 is formed by extrusion molding at an appropriate height.

The seal member 21 is integrally molded by wrapping around from the upper surface of the shoulder portion 4a to the upper portion of the side wall 5 up to a proper position indicated by a and protruding further outward from the side wall 5 by the side indicated by b. It is integrally molded with the amount of protrusion.

Further, the peripheral surface of the seal member 21 on the retainer center side is formed as an inclined surface with an appropriate inclination angle θ toward the outside of the vehicle, and is formed between the peripheral edge portion 1a of the vehicle body opening 1 and the shoulder portion 4a. When it is compressed by, it flexes and deforms to the outside of the vehicle so that it easily sticks out.

In this embodiment, the sealing member 21
Is formed into a hollow lip shape having a substantially semicircular cross section.

Further, a plurality of slits 22 communicating with the hollow portion are formed in the front-rear direction in the molding base portion of the inclined surface on the retainer center side of the hollow lip-shaped seal member 21 at an appropriate height.

The slits 22 are provided especially at the front and rear portions of the vehicle body opening edge portion corresponding to the curved corner portions C, F, C, R, but there may be a plurality of slits provided over the entire length.

According to the above-described structure of the embodiment, when the upper wall 4 of the holder portion 3 of the retainer 2 is overlapped with the peripheral edge portion 1a of the vehicle body opening portion 1 and the center portion of the upper wall 4 is fastened and fixed by the screw 15. The seal member 21 provided on the upper wall 4 is integrally molded from the shoulder portion 4a on the outer side of the vehicle to the upper side of the side wall 5 so as to protrude further toward the outer side of the vehicle than the side wall 5. Since the peripheral surface is formed as an inclined surface having an appropriate tilt angle θ to the outside of the vehicle, when the sealing member 21 is compressed between the peripheral edge portion 1a and the shoulder portion 4a, the sealing member 21 is moved to the outside of the vehicle. Due to the compressive deformation of the seal member 21 and the protruding action to the outside of the vehicle, the sealing member 21 absorbs the variation in the seal gap δ set between the peripheral edge portion 1a and the shoulder portion 4a, and these peripheral edge portions 1a. Between the shoulder and the shoulder By interposing with force, the sealability of the mounting portion of the retainer 2 can be improved.

More specifically, since the retainer 2 is long, it tends to inevitably twist, and the dimensional tolerance of the retainer 2 and the peripheral edge portion 1a of the vehicle body opening 1 or the retainer 2 The retainer center part may be screwed in at multiple places due to an error in assembling the peripheral part 1a of
In the case where the seal gap δ is fastened and fixed by means of No. 5, the seal gap δ inevitably varies in the front-back direction. In the small portion, the protrusion of the seal member 21 to the outside of the vehicle becomes large, and the seal reaction force can be made substantially constant over the entire length of the retainer 2.

Particularly in the present embodiment, the seal member 21
Is formed in the shape of a hollow lip having a substantially semicircular cross section, the tendency of the seal member 21 to protrude to the outside of the vehicle is promoted, and the seal gap between the peripheral edge portion 1a of the vehicle body opening 1 and the shoulder portion 4a is increased. The variation in δ can be absorbed more satisfactorily.

Further, since the slit 22 communicating with the hollow portion is formed in the molding base of the inclined surface forming the peripheral surface on the retainer center side of the hollow lip-shaped seal member 21, the front and rear of the opening edge of the vehicle body are formed. Curved corners C and F of
The seal member 21 can be flexibly deformed to the outside of the vehicle at the C and R portions, and the conformability of the shape of the seal member can be improved in the front-rear direction around the periphery of the vehicle body opening to further enhance the sealability. it can.

Although the seal member 21 is formed to have a substantially semicircular cross section in the above-described embodiment, the cross sectional shape is not limited to this, and may be any shape as long as it can be easily deformed to the outside of the vehicle.

Further, the seal member 21 may be formed in a hollow shape or may be formed of sponge rubber to be solid.

[0035]

As described above, according to the present invention, the following effects can be obtained.

According to the first aspect of the present invention, since the seal member is integrally formed with the shoulder portion on the vehicle outer side of the upper wall of the holder portion of the retainer, the conventional sticking work of the seal material is unnecessary, and the cost can be obtained advantageously. Of course, this seal member is integrally molded from the shoulder of the upper wall of the holder part to the upper part of the side wall so as to project outward from the side wall to the outside of the vehicle and the peripheral surface of the retainer center side to the outside of the vehicle at an appropriate inclination angle. To form an inclined surface with
When compressed between the vehicle body opening edge portion and the shoulder portion, it is flexibly deformed to the outside of the vehicle so as to easily protrude. It is possible to absorb the variation in the seal gap between the retainer and the portion, and to make the seal reaction force substantially constant over the entire length of the retainer to improve the sealability of the retainer mounting portion.

Further, in the portion where the seal gap is small, the amount of protrusion of the seal member to the outside of the vehicle is large, and displacement of the retainer toward the center of the vehicle body opening can be avoided, so that the weather strip and the door window panel are in close contact with each other. The state can be made substantially uniform over the entire circumference, and the sealing property of this portion can be improved.

Further, since the seal member is integrally formed on the shoulder portion of the upper wall of the holder portion as described above, the retainer will not be peeled off from the retainer even if the seal member is caught at the time of carrying in or carrying in the retainer. Since the stable mounting state can be maintained, a seal failure will not be induced when the retainer is assembled to the vehicle body.

According to the second aspect, since the seal member is formed in the shape of a hollow lip having a substantially semicircular cross section, when the retainer is fastened and fixed to the opening edge of the vehicle body, the seal member tends to protrude to the outside of the vehicle. The property is promoted, and the variation in the seal gap between the vehicle body opening edge portion and the shoulder portion can be absorbed more satisfactorily.

According to the third aspect, since the slit communicating with the hollow portion is formed on the inclined surface forming the peripheral surface on the retainer center side of the hollow lip-shaped seal member, the curved portion of the vehicle body opening edge portion is formed. In this case, the seal member can be flexibly deformed to the outer side of the vehicle, and the conformability of the shape of the seal member can be improved in the front-rear direction of the opening edge portion of the vehicle body to further improve the sealability.
