Description

[Detailed Description of the Invention] The present invention relates to an improvement of a synthetic resin fastener that is continuously fixed to the periphery of a window opening of an automobile in order to attach a molding to the periphery of a shield glass of an automobile.

As shown in FIG. 1A, a normal fastener 1 of this type has a lip portion 3 continuously curved toward the back surface on the upper edge of its long strip-shaped base 2, and a lip portion 3 curved toward the surface on the lower edge. A mounting piece 4 curved in a U-shape is continuously formed, and the strip base 2 is fixed to a panel 7 defining the periphery of a window opening of an automobile via double-sided adhesive tape 8. The molding 5 is attached to the periphery of the shield glass G by locking a clip 6 that holds the molding 5 between the mounting pieces 4.

However, the shape of the periphery of the window opening of a car is
As shown in FIG. B, especially the corner portion 9c located at the boundary between the upper portion 9a and both side portions 9b has an extremely curved shape.
As shown in FIG. 2, straight fastener parts 1a and 1b corresponding to the straight parts of the upper part 9a and both side parts 9b, and curved fastener parts 1c corresponding to the curved shape of the corner part 9c are divided, respectively. It adopted a configuration in which it was molded separately.

For this reason, in the case of conventional split fasteners, it goes without saying that a connecting means 10 is required to connect the ends of the straight fastener part and the curved fastener part, but a separate fixing operation to the panel 7 is also required. This not only increases the number of man-hours, but also
Even if the two are connected by the connecting means 10, a step or the like will occur at the joint between the straight fastener part and the curved fastener part, which will cause the problem that the locking state of the clip 6 holding the molding 5 will become unstable. had.

From this, when the fastener 1 is integrally molded in a straight line and is actually fixed to the panel 7, it is necessary to
A method of forcibly bending the corner portion 9c to match the curved shape of the corner portion 9c may be considered, but in this method, as shown in FIGS. 3A and 3B, However, at the forced bending point 1d of the fastener 1, the lip portion 3 is lifted up into a wavy state as shown in Figures A and C, so the appearance is significantly impaired. , it is said that it is not suitable for practical implementation.

Therefore, an improved split fastener disclosed in Japanese Utility Model Application Publication No. 58-39309 has been proposed.

Although not specifically shown in the drawings, this improved type of split fastener includes integrally molding only the upper part of the band-like base including the lip part on one of the split straight fastener parts, and extends the extended part to the other part. The fastener is arranged so as to butt against the end face of the straight fastener part, and to follow the curved shape of the corner of the window opening periphery.

Therefore, since such an improved split fastener places the flexible extension part at the curved corner part, there is no need to worry about wrinkles or undulations occurring in the lip part itself. This is causing problems.

That is, when fixing a fastener to a panel defining the periphery of a window opening, it is necessary to determine the fixing position of the fastener, and therefore, as shown in FIG. The band-shaped base 2 is fixed to the panel 7 by bringing it into contact with the panel 7 and determining the positional relationship between both 2 and 7. However, as mentioned above, the extension part of the improved split fastener is fixed to the panel 7. Since there is no lower part of the band-like base that performs a positioning function, the only way to fix this extended portion is to rely on the intuition of the operator.

For this reason, in the case of improved split fasteners,
Not only does the work of fixing the fastener become extremely complicated, but if the extension portion is misaligned, the appearance will be significantly impaired.

In addition, it is also required to butt this extended portion against the end face of the other linear fastener section, which further increases the complexity of the work and also Due to misalignment, etc., the butting condition becomes poor and the appearance is also impaired.
Furthermore, even if the extended portion is accurately butted against the end face of the other linear fastener section, an unnecessary seam line will be created at this butted portion, similar to the above-mentioned split fastener section. , it cannot be denied that the appearance is impaired.

Furthermore, even if the extended portion is fixed to the panel using double-sided adhesive tape, since only a small portion of the extended portion is fixed, the fixed state will naturally weaken and if an unexpected external force is applied, the lip portion may shift. There is also a good chance that it will move or float.

Therefore, the present invention was developed to effectively solve various problems of conventional fasteners, including the improved type of split fasteners. Assuming a synthetic resin fastener that is integrally molded in a straight line, it has a band-shaped base to be fixed, a lip part is formed on the upper edge of the band-shaped base, and a mounting piece is formed on the lower edge of the band-shaped base. , Cut out only the mounting piece located at a location corresponding to the curved corner of the periphery of the window opening of the automobile, and match the band-like base and lip portion at the location where the mounting piece is cut out to match the curved shape of the corner. A configuration was adopted in which the belt-shaped base was previously heat-formed into a curved shape, and the band-shaped base, which had been given the curved shape by the heat-forming, was adhesively fixed while its lower edge was in continuous contact with the bottom surface of the window opening periphery.

Hereinafter, the present invention will be described in detail based on an illustrated embodiment. Basically, the fastener 11 according to the embodiment is a panel that defines the periphery of a window opening via a double-sided adhesive tape, as shown in the figure. 7, a lip portion 13 is continuously formed on the upper edge of the strip base 12, and a mounting piece 14 curved in a U-shape is continuously formed on the lower edge of the strip base 12, so that the entire body is straight. Although it is based on a structure that is integrally molded into a shape, its features include the following points.

That is, in this embodiment, Fig. 4 A, B, and C
As shown in FIG.
4, and remove the strip base 12 and lip portion 13 at the location 11d where the mounting piece 14 is cut out.
Using a molding device or the like, the long strip base 12 is heated and formed into a curved shape that matches the curved shape of the corner portion 9c, and the lower edge thereof is attached to the panel 7. The panel 7 is configured to be continuously fixed along the panel 7 that defines the periphery of the window opening while being in continuous contact with the bottom surface of the window opening.

Therefore, unlike the fastener 11 according to this embodiment, which is forcibly bent, the fastener 11 has a curved corner portion 9c.
Since the portion 11d corresponding to the corner portion 9c is bent in advance including the lip portion 13, the corner portion 9c
There is no need to worry about the lip portion 13 at the corresponding location 11d lifting up into a wavy state or causing wrinkles, and at the corresponding location 11d, the band-shaped base 12 to be bent is formed on both sides over the entire back surface. Since it is securely fixed to the panel 7 via the adhesive tape, the lip portion 13 located on the curved corner portion 9c side is always maintained in a stable state like the lip portion 13 on the straight portion side. Even if an unexpected external force or the like is applied, there is no fear that the lip part 13 itself will be inadvertently shifted, moved, or lifted up, which will spoil the appearance.

Moreover, in this embodiment, unlike the above-mentioned improved split fastener, only the mounting piece portion 14 is cut out at the location 11d corresponding to the curved corner portion 9c, thereby achieving a positioning function when fixing. Since a configuration is adopted in which the band-shaped base 12 is left as it is, the lower end edge of the band-shaped base 12 is positioned with a positioning means not only in the straight part of the window opening periphery but also in the curved corner part 9c. Since the band-shaped base 12 can be continuously adhesively fixed while the lower edge of the band-shaped base 12 is brought into contact with the bottom surface of the panel 7, the fixing work becomes extremely easy, and the fastener 11 is It is now possible to always fix the product in a constant, ideal position.
Unlike the improved split fastener, there is no need to worry about the appearance being spoiled due to misalignment at the curved corner.

Furthermore, since this embodiment is based on a long straight fastener, it goes without saying that the fixing work is easier, but unnecessary seam lines due to butting are avoided, as is the case with split fasteners. There is no need to worry about it occurring.

In this embodiment, the reason why only the mounting piece 14 at the location 11d corresponding to the curved corner portion 9c is cut out is to facilitate the bending process of the band-shaped base 12 and the lip portion 13.

As described above, the present invention employs the above-mentioned configuration, and when fixing a fastener to the periphery of a window opening of an automobile, a band-shaped base that has been given a curved shape for a corner by heat molding in advance is used, and the lower end edge of the fastener is attached to a window opening. Since it is only necessary to fix the fastener while continuously contacting the bottom surface of the periphery of the window opening, work efficiency can be greatly improved, and the fastener can be kept constant not only on the straight part of the periphery of the window opening but also on the curved corner part. This means that it can be fixed in an ideal position, and there is no need to worry about the appearance being damaged.

In addition, in the case of the present invention, there is no exposed seam or waving at the lip part as in the conventional case.
From this point of view, the appearance is also very good.
