Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a fastener used for attaching a decorative molding to the periphery of, for example, a shield glass of an automobile.

"Prior Art" As a conventional fastener of this type, there are those shown in, for example, Japanese Utility Model Application Publication No. 18812/1983 or Japanese Utility Model Application Publication No. 50816/1989.

Each of these conventional fasteners is basically integrally molded from a synthetic resin material, and has a U-shaped gripping piece integrally formed on one side of a strip-shaped base, and the gripping piece has a A gap is formed between the inner surface and the surface of the band-shaped base body into which an engaging arm provided by the molding or a clip that holds the molding from the back side is inserted, and the engaging arm is engaged at an appropriate position on the inner surface of the free end side of the gripping piece. A locking part that engages with the joint part is formed, and the back side of the band-shaped base is fixed to the mounting step part of the body panel that defines the window frame of the automobile via double-sided adhesive tape, and the glass is fixed. After adhering and fixing to the body panel via the dumb rubber and adhesive, the engaging arm on the molding side is inserted into the gap between the gripping piece and the strip base, and the engaging part of the engaging arm is attached to the gripping piece. The molding is attached to the periphery of the glass by engaging with the locking part of the part.

``Problem that the invention aims to solve'' Since conventional fasteners are integrally molded from synthetic resin, they only require one processing step, which is advantageous in terms of manufacturing. Since it is only formed integrally by curving to one side of the band-shaped base, it forms a gap in which the insertion arm is engaged, so even if the engagement part of the engagement arm is engaged with the engagement part of the band-shaped base, it is not possible to As a result, it is undeniable that the gripping force on the intruding arm will naturally become weaker.

As a result, when an unexpected external force is applied, the free end side of the gripping piece sometimes opens, causing the engagement part of the molding side engaging arm to engage with the locking part of the opened gripping piece. There is a strong possibility that it may come off and cause a defect in the mounting condition of the molding.

Therefore, as shown in Japanese Patent Application Laid-Open No. 114615/1983, in view of the problems of the above-mentioned integrally molded fastener,
There has also been provided a fastener in which a strip-shaped base body and a gripping piece are separately molded.

Although the fastener of the separate molding die is not specifically shown, the strip-shaped base side is molded as a long body as in the past, but the part corresponding to the gripping piece is molded as a single block-shaped clip body. The block-shaped clip bodies are fixed to the band-shaped base body at regular intervals.

Therefore, this separately molded fastener is required to have a fixing structure for fixing each block-shaped clip to the strip-shaped base. Since the fastener is composed of a single block-shaped clip body, it is necessary to attach a complicated fixing structure to the band-shaped base body and the clip body, which has the problem of unnecessarily increasing the size of the fastener itself, and the presence of the clip body. Even if it is possible to reliably grip the engaging arm on the molding side in some places, it is not possible to grip the engaging arm in places where the clip body is not present.
If the number of clips used is small, there is a problem in that the mounting state of the molding becomes unstable.

Therefore, in order to eliminate the instability of the molding installation state, a large number of clip bodies must be used. Since the work becomes extremely difficult, new problems arise from the viewpoint of workability.

Also, normally, the mounting steps of the body panel that define the window frame of an automobile are given a predetermined curved shape on the upper side and side side. If the clip body corresponding to the gripping piece is molded into a single block and the block-shaped clip body is fixed to the band-shaped base body, as in a molded fastener, the fastener Since the flexibility required for the fastener itself is significantly reduced, it is no longer possible to follow the curved mounting step of the body panel, and there is a good chance that the fastener itself will not be properly fixed.

``Means for Solving the Problems'' Therefore, the mounting fastener of the present invention was developed to effectively solve the problems of the separately molded mold, and it A strip-shaped base fixed to the mounting step of the panel and a gripping piece that cooperates with the strip-shaped base to grip the engagement arm on the molding side are separately molded into elongated bodies of desired dimensions. For the base body, a convex strip is formed in a continuous manner in the longitudinal direction approximately at the center thereof, and the back surface side is empty, and for the gripping piece, the central part in the width direction is curved in shape and protrudes outward. A locking portion is formed on the inner surface of the upper free end to engage the engaging portion of the molding side engaging arm, and the central portion of the curved gripping piece is fixed to the convex strip of the strip-shaped base via a fixing means. When this happens, a space is defined between the upper inner surface of the gripping piece and the corresponding surface of the band-shaped base body to allow the insertion of the molding-side engaging arm, and the lower end of the gripping piece comes into contact with the corresponding surface of the band-shaped base body. It was adopted.

``Function'' Accordingly, in the present invention, by simply fixing the widthwise central portion of the gripping piece to the protruding strip of the band-like base body through the fixing means, the long band-like base body and the gripping piece can be easily integrated. In addition, since the fixing means is accommodated in the hollow space on the back surface of the protruding strip formed on the strip-shaped substrate side, this greatly contributes to miniaturization of the fastener itself.

Furthermore, since the elongated gripping piece has a curved shape with its widthwise central portion protruding outward, when it is fixed to the strip-shaped base, the lower end elastically abuts on the corresponding surface of the strip-shaped base. The reaction force makes it possible to narrow the opening of the cavity defined between the inner surface of the upper free end where the locking part is formed and the corresponding surface of the strip base. It becomes possible to strengthen the gripping force on the engaging arm, and
In this state, it is possible to reliably grip the engaging arm on the molding side at any location on the fastener.

"Examples" Hereinafter, the present invention will be described in detail based on each example illustrating the present invention. In addition, each of the examples described below,
The belt-shaped base body and the gripping piece, which work together to grip the engagement arm on the molding side, are separately molded as long bodies of desired dimensions, but the difference is that the gripping piece is fixed to the belt-shaped base body. The fixing means have been changed respectively.

First, as shown in FIG. 1, the fastener according to the first embodiment includes a strip-shaped base 1 fixed to a mounting step of a body panel defining a window frame via a double-sided adhesive tape; The gripping pieces 2, which cooperate with each other to grip the insertion arm of the molding or the clip holding the molding, are separately molded from a synthetic resin material as elongated bodies having the same desired length.

As shown in the figure, for the former band-shaped substrate 1, a convex strip 3 is continuously formed in the longitudinal direction approximately at the center of the surface thereof, protruding like a protuberance and having a hollow portion 4 on the back surface side. The structure is such that perforations 5 are formed in the strip 3 at regular intervals.

On the other hand, the latter gripping piece 2 is formed into a curved shape in which the central part 2a in the width direction protrudes outward in the longitudinal section, and has a pin hole 6a on the inner surface of the central part 2a. The piece parts 6 are formed at regular intervals, and a locking part 7 for engaging the engaging part of the engaging arm is integrally formed on the inner surface of the upper free end side, and the lower end part is formed on the inner surface of the strip-shaped base body 1. The structure is such that it comes into elastic contact with the corresponding surface.

Therefore, as shown in FIG. 2A, the engaging piece 6 on the gripping piece 2 side is inserted into the hollow space 4 on the back surface of the protruding strip 3 through the corresponding perforation 5 on the strip base 1 side, and each of the engaging pieces is inserted. Inlet part 6
By fitting the lock pin 9 into the pin hole 6a, the elongated strip-shaped base 1 and the gripping piece 2 can be easily fixed. A space 8 is defined between the upper inner surface of 2 and the corresponding surface of the strip base 1 to allow the engagement of the molding side engagement arm. Since it has a curved shape and its lower end is brought into contact with the corresponding surface of the strip base 1, the void 8 at the free end side opening where the locking part 7 is formed is naturally smaller than other parts. will be narrowed down.

In addition, in this fixed state, the fixing means for fixing the strip base 1 and the gripping piece 2 is accommodated in the hollow space 4 on the back surface of the protrusion 3 formed on the strip base 1 side, so the fastener itself can be miniaturized. It will also be able to contribute greatly.

Therefore, when attaching the molding M to the periphery of the glass G via the clip 14 using the fastener of the first embodiment, first, as described above, the long strip-shaped base 1 and the gripping piece 2 are attached. Once the back side of the strip base 1 is fixed to the mounting step Pa of the body panel P that defines the window frame of the automobile via the double-sided adhesive tape 10, the rest is as follows.
As in the past, the glass G is adhesively fixed to the body panel P via the dam rubber 12 and the adhesive 11, and the engaging arm 15 of the clip 14 is connected to the gripping piece 2 and the strip-shaped base 1.
When the engaging portion 15a of the engaging arm 15 is engaged with the locking portion 7 of the gripping piece 2, the second
As shown in FIG. B, the molding M is attached to the periphery of the glass G.

Moreover, in the installation state of this molding M,
The elongated gripping piece 2 exhibiting a curved shape has an abutting action on the strip-shaped base 1 at the lower end, and the clip 14
While actively pressing the engaging arm 15 of the engaging arm 15 toward the band-shaped base 1 side, the engaging part 15 of the engaging arm 15 is attached to the engaging part 7 of the engaging arm 15.
a is engaged, this reaction force strengthens the gripping force on the engaging arm 15, ensuring a reliable gripping state, and even if an unexpected external force is applied to the molding M. This prevents the free end of the gripping piece 2 from opening inadvertently.

Moreover, since the gripping piece 2 that cooperates with the band-shaped base 1 to grip the engagement arm 15 of the clip 14 is formed as a long body with the same dimensions as the band-shaped base 1,
It becomes possible to grip the engagement arm 15 with the strip base 1 and the gripping piece 2 at any location, and from this point of view as well, it is ensured that the molding M is always reliably and stably attached to the periphery of the glass G. That will happen.

Furthermore, if the fastener is composed of the strip-shaped base 1 and the gripping piece 2 which are molded separately, in this embodiment, both 1 and 2 are molded as elongated bodies, so the fastener is formed first. Compared to the separately molded type fastener described above, the fastener itself can sufficiently exhibit the flexibility required, and can also sufficiently follow the curved mounting step Pa of the body panel P.
The secure fixation of the fastener itself is also guaranteed.

In this embodiment, the molding M is attached indirectly via the clip 14, but it goes without saying that the same effect can be achieved even when a molding M that is directly provided with an engaging arm is attached.

As shown in FIG. 3A, the fastener according to the second embodiment has a plurality of holes 21 formed in the central part 2a of the curved gripping piece 2 made of resin and corresponding to each of the perforations 5 formed in the convex strip 3 of the strip-like base body 1. The holding piece 2 and the strip-like base body 1 are integrally fixed by forming only the holding piece 2 and the belt-shaped base body 1 by aligning each hole 21 with the perforation 5 of the protruding strip 3 and fixing it with a rivet 22 as shown in FIG. This is what was done.

As shown in FIG. 4A, the fastener according to the third embodiment has protrusions 23 integrally formed at regular intervals on the inner surface of the central part 2a of the curved gripping piece 2 made of resin, and each protrusion 23 is formed into a convex strip. 3 from the corresponding perforation 5 to the cavity 4
The gripping piece 2 and the strip-like base body 1 are integrally fixed by melting 24 the tip of each protrusion 23 as shown in FIG. 2B. In this embodiment, a separate spacer 25 is interposed as shown in FIG.
It is also optional depending on the implementation.

As shown in FIG. 6A, the fastener according to the fourth embodiment includes a fixing piece 2 made of synthetic resin and having a plurality of protrusions 26a that are inserted into the perforation 5 of the protrusion 3 from the back side.
6 is separately molded, and the inner surface of the central portion 2a of the resin curved gripping piece 2 is simply welded by ultrasonic welding or the like to each protrusion 26a of the fixing piece 26 projecting outward from each perforation 5 as shown in FIG. Thus, both 1 and 2 are integrally fixed.

The fastener according to the fifth embodiment differs from the above-mentioned embodiments in that the curved gripping piece 2 is formed of a metal plate, and as shown in FIG. While the arms 28 are integrally formed, a pair of perforations 5 into which the bent arms 28 are inserted are formed in the convex strips 3 of the band-shaped base 1, and each fold of the gripping piece 2 is formed as shown in FIGS. The curved arm 28 is connected to the corresponding perforation 5 of the protrusion 3.
The metal curved gripping piece 2 is inserted into the hollow part 4 by bending each bending arm 28 outward.
The belt-like substrate 1 made of resin is integrally fixed to the belt-like base body 1 made of resin. In addition, even in such an example,
It is also optional, depending on the implementation, to bend the bending arm 28 outward with a spacer 29 as shown in FIGS. 8A and 8B.

The manner in which the molding M is attached to the periphery of the glass G using the fastener having the fixing means shown in each of the above embodiments is the same as in the first embodiment.

"Effects of the invention" As described above, although the present invention is based on the premise of a separately molded fastener, by adopting the above-mentioned new structure, it is possible to By fixing the central part of the gripping piece using a fixing means, the long strip-shaped base body and the gripping piece can be easily integrated, so the work of fixing them is much easier compared to the conventional separate molding type. This is greatly simplified, and the fixing means fits within the space on the back surface of the protrusion formed on the strip-shaped base, thereby greatly contributing to downsizing of the fastener itself.

Moreover, the elongated gripping piece has a curved shape with its widthwise central part protruding outward.
When fixing to the strip-shaped base, the lower end comes into contact with the corresponding surface of the strip-shaped base, and the reaction force causes the opening of the air defined between the inner surface of the upper free end forming the locking part and the corresponding surface of the strip-shaped base. This makes it possible to strengthen the gripping force on the engaging arm on the molding side, and in this state, the fastener can be tightened at any point on the molding side. Since it becomes possible to grasp the engaging arm, in any case, a reliable and stable mounting state of the molding is ensured.

Furthermore, although the fastener of the present invention is composed of a strip-shaped base and a gripping piece that are molded separately, since both of these are molded as elongated bodies, the fastener itself can sufficiently exhibit the flexibility required. This ensures that the fastener itself is securely fixed by following the curved mounting steps of the body panel.
