The present invention relates to a weather strip in which a pad of a sealing material is inserted into the molded part.

  FIG. 1 shows an open top car, and FIG. 2 shows the details of part a in FIG. 1. The open top car includes a middle roof panel 1 and a roof panel 2, and each panel 1 and 2 is individually provided. The deck cover 3 can be opened and closed to be stored in the tonneau. Each of the panels 1 and 2 is provided with weather strips 4 and 5 which are elastically contacted with the door glass 6 and seal between the door glass 6 and when the panels 1 and 2 are closed as shown in the figure. As shown in FIG. 2, the molded portions 4a and 5a at the ends of the weather strips 4 and 5 are connected in a state where the inclined surfaces are overlapped with each other. In the figure, the triangle mark indicates the mold forming part on the side of the blacked-out part, and the extruded part on the side of the non-painted part. The same applies to the following drawings.

As is the case with the weather strip of a hard top car, the weather strips 4 and 5 of the open top car have a weather strip hollow seal in order to increase the sealing reaction force with the door glass 6 and improve the sealing performance. A pad of sealing material made of sponge rubber or solid rubber may be inserted into the part. In many cases, such pad insertion is partially inserted into a required portion such as a molded portion in order to reduce costs. Patent Document 1 below describes a weather strip for a hard-top car that is attached to a door opening edge of a vehicle body and has a pad inserted into an end portion and a molded part of a corner.

  There are various types of molded parts at the end of the weather strip, such as those in which the shape of the end is inclined as shown in FIG. 2 and those that are perpendicular to the longitudinal direction. Regardless of the shape of the end of the molded part, the pad is often cut directly in the direction perpendicular to the longitudinal direction, and the end of the pad is inclined as shown in FIG. When the mold molding parts 4a and 5a shown in FIG. 2 are pushed and inserted through the core take-out hole 10, as shown in FIG. 3, the door glass includes a part where the pad 7 of the mold molding part 5a is inserted and a part where there is no pad. The reaction force of the weather strip was different when the seal was sealed, and there was a dislike that the sealing performance deteriorated in the portion where the reaction force without the pad was low.

  An object of the present invention is to provide a weather strip having improved sealing performance of a molded part into which a pad is inserted.

The invention according to claim 1 is attached to a door opening edge of a car body of a hard top vehicle or a roof side of an open top vehicle, and weatherstrips 4, 5 that elastically contact the door glass 6 and seal between the door glass 6 are sealed. In the weather strips 4 and 5 in which the pad 21 is inserted in order to increase the surface pressure with the door glass 6 in at least the end molding portions 4a and 5a out of the total length of the weather strip. parts 4a, 5a forms a by end surface is closed by an end wall 13 edge shape is tapered, the pad 21, a tapered shape in which the end face shape of the end corresponding to the edge shape of the molded part 4a, 5a the molded part 4a forms an, in 5a, the pad 21 is loaded to the terminal and said pad 21 is left and the other end which can be seen through the central core extraction hole 10 and the one end Referred shaped to form a substantially symmetrical shape of the tapered, characterized in that it is formed by different in shape by the rotation orientation in plan view.

Pad of the present invention, the pad end also to name the same tapered when one end which forms a shape corresponding to the edge shape of the molded part, ie the edge shape of the molded part, for example, tapered shape.

An example of the other end of the pad having a different shape depending on the direction of the rotational direction in plan view is a taper. For example, when the end shape of the mold forming portion is tapered, one end of the pad is tapered, but when the other end of the pad is also tapered, the cross-sectional shape of the pad may be a parallelogram or a substantially parallelogram. Examples include a shape and a symmetrical trapezoidal shape or a substantially trapezoidal shape. The cross-sectional shape of the pad may be solid or hollow.

  As the material of the pad, solid rubber or sponge rubber is used as in the conventional pad, but other materials can be used.

According to the first aspect of the invention, since the pad is loaded up to the end of the mold forming portion at the end of the weather strip, there is little change in the reaction force of the weather strip when the door glass is sealed, and at the end of the mold forming portion. It is possible to improve the sealing performance. In addition, as is the case with the molded portions 4a and 5a shown in FIG. 2, when the end surface of the molded portion is closed, the inserted pad cannot be seen from the end surface of the molded portion. For such a molded part, the pad is inserted by being pushed into the molded part from the core extraction hole of the molded part, but whether the inserted pad is inserted in the proper direction in the rotational direction, that is, the end face of the pad It is not possible to confirm whether or not the shape is inserted in a state that matches the shape of the end portion of the molded part.

On the other hand, as in the pad of the present invention, when both ends are formed in a left-right symmetric or substantially left-right symmetric taper shape and the other end is formed in a different shape depending on the direction of the rotation direction in plan view, By looking at the shape of the other end of the pad through the centering hole, it is possible to check whether the pad is inserted properly, that is, whether the pad is inserted in a predetermined proper direction. The pad can be loaded in an appropriate direction by adjusting the shape of the other end of the pad so as to have a required direction by rotating the pad through the center extraction hole. Further, the change in reaction force at both ends of the pad can be reduced.

  4 and 5 show a portion corresponding to FIG. 3 of the weather strip 5 attached to the roof side of the roof panel 2 of the open top vehicle shown in FIG. 1, and FIG. 6 shows a line AA in FIG. 6 shows a cross section of a mold forming portion 5a shown in FIG. 6, which is attached to a retainer 8 attached to the roof side, and is formed continuously from the attachment base portion of the extrusion forming portion 5b, and the attachment base portion. 9, a hollow seal portion 11 that elastically contacts the window glass 6 and seals between the window glass 6, and a covering lip 12 that covers the retainer 8, and the end wall 13 that closes the end face is inclined downward. An inclined taper shape is formed, and an angled attachment portion 14 is integrally formed at the end. The vertical portion 14a of the mounting portion 14 is fixed to the end of the roof panel with a set screw. In the figure, reference numeral 15 denotes a screw hole indicating a set screw. The structure described above is the same as the structure of the mold forming portion 5a of the conventional weather strip 5 shown in FIGS. 2 and 3, and there is no change.

The weather strip shown in FIGS. 4 and 5 is different from the weather strip portion shown in FIG. 3 in that the end of the weather strip shown in FIG. A hollow pad 18 made of solid rubber or sponge rubber having a taper shape inclined in the same direction as the end wall 13a of 5a and displaying a circle mark 19 as a display means on its peripheral surface, 4 and 5 in which the one end of the pad formed in a tapered shape is joined to the end wall 13 of the mold forming part 5a when 18 is inserted into the hollow seal part 11 of the mold forming part 5a in a predetermined proper direction. The circle mark 19 is displayed at a position where it can be seen from the center core take-out hole 10 when inserted in the state shown.

According to the weather strip , the pad 18 is loaded up to the end of the mold forming part 5a, so that the reaction force change when sealed against the door glass is small compared to the conventional structure shown in FIG. The sealing performance at the terminal can be improved, and when the pad 18 is inserted into the hollow seal portion through the core extraction hole 10, the pad 18 is pushed by being pushed so that the mark 19 can be seen through the center extraction hole 10. 4 and the like can be inserted in a predetermined appropriate direction.

Weather strip embodiment of the present invention, as shown in FIG. 7, but using the pad 21 formed at both ends symmetrically shaped tapered instead of above the pad 18.

  In the present embodiment, there is little change in reaction force at both ends of the inserted pad 21, the sealing performance can be further improved, and whether or not the inserted pad 21 is inserted in a predetermined appropriate direction is determined. The effect that it can confirm by seeing the taper shape of a pad other end from the core extraction hole 10 is produced.

  In still another embodiment, both ends of the pad are tapered and have a bilaterally symmetric shape, and as a display means, for example, the above-mentioned ◯ mark is displayed, and the direction of the taper of the pad end through the center extraction hole Whether or not the pad is inserted can be determined from either of the circle mark and the circle mark.

  The pad of each of the above embodiments is inserted into the mold forming portion of the weather strip that is attached to the roof side of the roof panel of the open top vehicle. In the weather strip 4 that is attached to the roof side of the middle roof panel, Can also be inserted in the same way into the molded part 4a, and also inserted into the molded part integrally formed at the end of the weather strip attached to the door opening edge of the car body of the hardtop car. The same effect can be produced.
