Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a molded portion of a weatherstrip of a hard top vehicle.

[0002]

[Prior art]

 Description will be made with reference to FIGS. 1 to 5. In the figure, the symbol with one of the median lines from the apex angle of the isosceles triangle filled in is used.The filled side represents the mold forming part, and the non-filled side represents the extruded part. . Conventionally, for example, the following has been used as the mold forming part of the end of the weather strip that is attached to the waist line of the center pillar part of a hard top car. In FIG. 3, reference numerals 31 and 31 are base portions fitted respectively to a pair of retainers of front and rear symmetrical center pillars (not shown), and 32 and 32 are end surfaces of the door glasses 21 and 21 when the front and rear doors 20 and 20 are closed. And a hollow seal portion which is elastically contacted with the inner surface, respectively, which are integrally connected to the base portions 31 and 31 respectively, in order to compensate for the hardness difference from the weather strip extrusion molding portion 40 shown in FIG. The pad thickness is increased, the pad 70 is inserted, and as shown in FIG. 4, the tongue-shaped projection 80 is projected from the base 31 side toward the seal surface. Reference numerals 43 and 44 in FIG. 5 are bridges that increase the sealing pressure of the hollow seal portions 42 and 42 in front of and behind the weather strip extrusion molding portion 40. For the former, the hollow portion is divided into three from the outside to the inside. Bridges 43, 43, one end of which is connected to the front and rear portions of the base 41, and the other end of which is connected to the inner surface of the door glass 21, 21. The latter is a long bridge that extends forward and backward. It consists of only 44. 39 is a central mall part.

However, in the molded portion of the weather strip of the above conventional hard-top vehicle, the one with an increased wall thickness has rough skin, and the one with the pad 70 inserted as shown in FIG. 3 has a large number of parts and assembly steps. In addition, as shown in FIG. 4, the tongue-shaped projection 80 is provided, and the object to be molded such as rubber injected at the time of molding does not knead and becomes shorter than the set dimension (short or Is a broken state), and there is a problem that it breaks and affects productivity. Further, if a load difference occurs at the connecting portion between the weather strip extrusion molding portion 40 and the weather strip type molding portion 30, the sealing load may change, which may deteriorate the sealing property such as water leakage.

[0004]

[Problems to be solved by the device]

 The problem to be solved is that the die-molded portion of the weather strip of the above conventional hard-top vehicle has a hardness difference between the weather strip extruded portion 40 and the sealing surface, and in order to secure the sealing property, the The one with increased thickness has rough skin, the one with the pad 70 inserted increases the number of parts and the assembling process, and the one with the tongue-shaped projection 80 has the object to be molded such as rubber injected at the time of molding. It means that the product does not rotate and becomes shorter than the set size (shorts) or breaks, affecting productivity.

[0005]

[Means for Solving the Problems]

 This will be described with reference to FIGS. 1 and 5 to 8. According to the present invention, in the weather strip type molding part 50 of a hard top vehicle, a moving push piece 56 is provided on the back surface of the sealing surface of the hollow seal part 52 toward the base part 51 and the hollow part of the base part 51 is hollow. A fixed pressing piece 57 is provided on the surface of the seal portion 52 side so as to project toward the sealing surface, the door 20 is closed, and the hollow glass 52 is deformed by pressing the door glass 21. , 57 are abutted against each other, or the tips of both pressing pieces 56, 57 are brought into contact with the opposite surfaces to increase the sealing pressure of the hollow seal portion 52.

[0006]

【Example】

 Examples will be described. Reference numerals 20 and 20 are front and rear doors, 21 and 21 are door glasses attached to the front and rear doors 20 and 20, and 50 is a molding portion of a center pillar end portion of a weather strip of the present invention. And is configured as follows. That is, 51 and 51 are respectively fitted to a pair of front and rear retainers (not shown), and 52 and 52 are the end surfaces and inner surfaces of the door glasses 21 and 21 when the front and rear doors 20 and 20 are closed. Hollow seal portions that are elastically contacted with each other are integrally connected to the base portions 51 and 51, respectively, and both have a thin sealing surface to prevent rough skin. Reference numeral 56 designates a pressing piece projecting toward the base portion 51 on the back surface of the sealing surface of each hollow seal portion 52, and 57 projects on the surface facing the hollow seal portion 52 of the base portion 51 toward the seal surface. It is a push piece that has been installed, in which the door 20 is closed and the door glass 21 is pushed to deform the hollow seal portion 52, but the push pieces 56 and 57 are butted together or, as shown in FIG. The tips of the pressing pieces 56 and 57 are brought into contact with the base portion or the back surface of the sealing surface to increase the sealing pressure of the hollow seal portion 52. More specifically, it is preferable that the lengths of the pressing pieces 56 and 57 are set to a gap of about 2 to 3 mm in the non-contact state with glass.

The operation will be described. Even if the wall thickness of the sealing surface of the hollow seal portion 52 is reduced, the door 20 is closed and pushed by the door glass 21 to deform the hollow seal portion 52. The hollow seals of the weather strip extruded part 40 are made by abutting 57 with each other to increase the sealing pressure of the hollow seal part 52 (although it is necessary to slightly adjust the length and thickness of the pressing pieces 56, 57). Since the difference in hardness from the sealing surface of the portion 42 is eliminated, the quality is stable, the number of parts is small, and the number of assembling steps and the manufacturing cost are reduced.

[0008]

[Effect of device]

 Since the present invention is configured as described above, there is almost no difference in hardness between the sealing surfaces of the weather strip type molding portion 50 and the weather strip extrusion molding portion 40 of the hollow sealing portions, and the sealing performance is improved. The number of parts is reduced, and therefore the assembly man-hours and manufacturing costs are reduced.
