Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a weather stripping structure for a retractable roof for a vehicle, and in particular, to a weather stripping structure for a retractable roof of a vehicle, and particularly for weather stripping for sealing on the peripheral edge of a glass or resin glued panel.
Regarding structure.

Recently, glass and resin materials with excellent lighting are being used for retractable roof panels for vehicles. As shown in FIGS. 1 and 2, this type of roof panel 3 is fitted into a roof opening 4 provided in a heavy-duty roof panel 2, and is connected via a guide rail and a lid panel drive mechanism (not shown). It can slide and tilt. A frame-shaped retainer 5 is attached to the periphery of the lid spring 3 to maintain the rigidity of the lid panel 3 and to be used by the lid panel drive mechanism, and a frame-shaped retainer 5 is attached to the periphery of the roof opening when the lid panel 3 is closed. A weather strip W is attached to seal between the two. Conventionally, this type of weather
As shown in FIG. 2, the strip W includes a mounting base 7 in which a fitting groove 8 is formed along the longitudinal direction of the weather strip W in order to be inserted and fixed into the mounting franchise of the retainer 5, and a mounting base 7 on the inside thereof. A pair of bottom holding lips 8, 10 extending from the upper and lower ends of the wall in the ice direction f and mounted to cover the peripheral edge of the lid panel 3, and a lid panel 3 formed protruding from the outer wall of the mounting base 7. and a seal portion 11 that elastically seals between the roof panel 2 and the edge of the roof opening 4 when the roof panel 2 is closed. To fix this weather strip W, first use a jig to attach the weather strip to the periphery of the lid panel 3.
Attach the retaining lips 8 and 10 of the strip W, then place the retainer 5 on the lower surface of the peripheral edge of the lid panel 3 with the adhesive S applied, and insert the mounting flange 6 into the fitting groove 8 of the mounting base 7. This is done by Reference numeral 12 is fitted along the inner peripheral edge of the retainer 5, and the upper end is connected to the lid panel 3.
This is a dam rubber that comes into contact with the F side of the rubber to prevent the adhesive S from flowing out.

However, the weather protection of such retractable roofs for vehicles is
In the strip special issue structure, Weatherstrip W
The lint panel 3 was provided with a fitting groove 8 corresponding to the shape of the mounting flange 6 of the retainer 5, and the mounting structure was such that the lint panel 3 was simply inserted by covering the mounting flange 6 from above.
During sliding or tilting operations, the lower end 13 of the mounting base 7 of the weatherstrip W may curl up due to the sliding resistance of the seal portion 11 generated between the opening edge and the mounting base 7, or the mounting base 7 may close to the mounting flange of the retainer 5. In addition, the sealing effect of the weather strip W is uncertain, such as the weather strip W floating up and getting bent when the lid panel 3 is opened and closed, and the weather strip W getting caught when opening and closing the lid panel 3, making it impossible to operate smoothly. There was a problem. Further, there is a problem in that the lower end portion 13 of the weather strip W is curled or raised, resulting in a deterioration in appearance quality.

The present invention has been made by focusing on the above-mentioned problems in the prior art, and its purpose is to improve the sealing of weather strips by preventing the lower end of the weather strip from turning over, bittering, lifting, etc. The reason lies in the fact that it has made it possible to secure sex easily. And this invention is.

The gist is that the base of the weather strip is adhesively fixed to the mounting flange of the retainer.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

FIG. 3 shows a first embodiment of a weather pump structure according to the present invention. Weather related to this example
In the strip W, a fitting groove 8 that is inserted into the mounting flange 6 of the retainer 5 is formed along the longitudinal direction of the mounting base 7 as in the conventional case, and a pair of fitting grooves 8 are formed along the longitudinal direction of the mounting base 7 on the inner and outer peripheral walls of the mounting base 7. The upper and lower holding lips θ, 10 and the seal portion 11 are formed respectively, but unlike the conventional case, the fitting groove 8 is
Among the peripheral walls forming the groove, a groove 16 as an adhesive reservoir is formed in the outer peripheral wall 15 of the groove that faces the outer surface 14 of the mounting flange 6, and the F end 1 of the outer peripheral wall 15 of the groove is formed.
3 slightly extending inward to keep the lower edge of the groove 16 cold.

Therefore, according to this embodiment, the weather strip W is first applied to the peripheral edge of the lint panel 3 using a jig (not shown).
After installing the upper and lower holding lips 8 and 10 and determining the mounting position of the weather strip W, adhesive S is applied to the groove 16. Then, with adhesive S applied, retainer 5
is placed on the lower surface of the outer peripheral edge of the lid panel 3, and the mounting flange 6 of the retainer 5 is inserted into the fitting groove 8. In this case, the groove outer periphery ji 15 is adhesively fixed to the outer surface 14 of the retainer 5 through the coating 4j L and adhesive S in the groove 16, and the lower end 13 of the groove outer peripheral wall 15 is attached to the mounting flange 6. The adhesive S is prevented from leaking by contacting the rising base 17 of the adhesive S. As a result, the end of the mounting base 7 of the weatherstrip W does not curl up even against the sliding resistance of the seal portion 11 that occurs when the lid panel 3 slides or tilts, unlike the conventional method. As such, there is no risk of deterioration of sealing performance and problems when the Rad Panel 3 is operated. As a means of applying 711 the adhesive S into the groove 16, after attaching the weather strip W to the retainer 5, turn over the lower end 13 of the base 7 of the weather strip W and glue it inside the groove 16. Agent S can also be applied.

Figures 4 and 5 show a second embodiment of the present invention, which prevents the weather strip W from turning over and getting hit, and improves workability when installing the weather strip W. This is what I did. That is, in this embodiment, a plurality of through holes 18 are provided in the mounting flange 6 of the retainer 5 along the longitudinal direction, and the adhesive S applied to the retainer 5 passes through the through holes 18 to the groove 16 of the weather trip W. It is designed so that it flows into the interior.

Therefore, according to this embodiment, when the weather strip W is attached to the peripheral edge of the lid panel 3 and the retainer 5 is fitted and fixed from below, the mounting flange 6 of the retainer 5 is attached to the weather strip W. As the retainer 5 is inserted into the fitting groove 8, the adhesive S applied to the retainer 5 in a slightly larger amount is pushed and flows into the groove 18 from the through hole 18, and through the adhesive S that has flowed into the groove 16. Thus, the groove outer peripheral wall 15 and the outer surface 14 of the mounting flange 6 can be adhesively fixed. It should be noted that the shape and number of through holes 18 are not limited to those in the above embodiment, and can of course be changed as appropriate.

FIG. 8 shows a third embodiment of the present invention, in which the lower end extension 13' of the weather strip W covers the lower part of the retainer 5. In this embodiment, a groove 1 ft' as an adhesive reservoir is provided on the inner wall of the extension 13', and a through hole 1B' for adhesive leakage is provided at a position near the mounting flange of the retainer 5 corresponding to the groove 18'. It has been established.

Therefore, in this embodiment, the adhesive S applied to the retainer 5 side flows into the groove 16' from the through hole 18' when the retainer 5 is removed, and this adhesive S adhesively fixes the lower end extension 13' to the retainer 5. This can prevent the extension portion 13' from curling up.

Furthermore, - the concave groove in the above embodiment is a weather strip W.
It is not necessary to provide the concave groove 16 over the entire length of the groove 16, and when bonding is performed partially in the first embodiment, the groove 16 may be provided partially, and in the case of the second and third embodiments, the groove 16 may be provided partially. ,
Gate structure 18.18 corresponding to through hole 18.18'
' may be provided. Further, in the above embodiment, a groove is formed on one side of the circumferential wall of the groove part of the fitting groove 8 and filled with the adhesive S, but a groove is also formed on the other side circumferential wall to remove the flange 6.
By adhesively fixing it to the inner surface of the sheet, it is possible to improve the effect of preventing it from turning up. Furthermore, a pore that communicates with the outside may be provided below the groove, and excess adhesive in the groove may flow out from the pore and be wiped off. Furthermore, instead of separately providing a groove as an adhesive reservoir as in the above embodiment, adhesive may be applied thinly to the circumferential wall of the vortex portion for bonding. Also, the outer edge of the cooled panel and the retaining lip 9. ]O may be filled with an adhesive to fix the retaining lips 8, 10 to the peripheral edge of the lid panel 3.

As explained above, according to the weatherstrip mounting structure according to the present invention, the additional issue part of the weatherstrip and the retainer are fixed with adhesive without complicating the conventional mounting work. To ensure that the lower end of the weather strip is securely fixed, and to reliably prevent the weather strip end from curling up or floating, which could occur when the lid panel slides, etc., as in the past. I can do it.
