Description

[Detailed Description of the Invention] "Industrial field of application" The present invention is applied to a curved corner portion of a window frame of an automobile, particularly when a decorative glass molding is attached along the periphery of the windshield glass of the automobile. The present invention relates to an improvement of a dedicated fastener used for attaching a glass molding.

"Prior Art" When attaching a glass molding along the periphery of a windshield glass, a resin fastener that is usually fixed to a vehicle body panel that defines a window frame of an automobile is generally used. The basic structure of is a U-shaped structure in which a lip piece that comes into contact with the bent curved surface of the panel is integrally formed on the upper end of the strip-shaped base, and a locking claw that locks the molding leg is provided on the lower end of the strip-shaped base. The locking strips are integrally formed so as to stand up.

However, especially when a glass molding is attached to a curved corner portion of a window frame, a dedicated fastener such as shown in Japanese Utility Model Laid-Open No. 60-54620 is used, and the dedicated fastener is a window frame. While notching the part of the locking strip corresponding to the curved corner part of, over a certain range,
A configuration is adopted in which the strip-shaped base body corresponding to the cutout region is bent into a curved shape that matches the corner shape of the window frame.

Therefore, when such a dedicated fastener is used, at least the portion corresponding to the corner of the window frame has no locking strip for locking the leg on the molding side, and moreover, with respect to this corresponding portion. Has a curved shape that matches the shape of the corner portion in advance, so that the strip-shaped base body of the fastener can be reliably fixed to the panel surface while easily following the shape of the window frame corner portion.

However, in this dedicated fastener, the structure in which the locking strips corresponding to the window frame corners are cut out is effective in that the belt-shaped base is fixed following the shape of the window frame corners. However, in the cutout area of the locking strip, the leg on the molding side cannot be locked by the locking claw of the locking strip. Side corners are not locked to the locking claws of the locking strips, so the corners of the molding are inadvertently lifted from the fastener, or unnecessary between the corners of the molding and the panel surface. However, there is a problem in that a large gap is generated and the appearance is significantly impaired.

For this reason, the applicant has already provided the improved fastener of Japanese Utility Model Laid-Open No. Sho 63-18193.

Although not specifically shown, the improved fastener is formed into a shape that matches the curved shape of the corner of the window frame on the premise of the fastener structure as it is, and has a locking claw on the surface facing the belt-shaped base. Even if a corner piece member integrally formed is provided, and the corner piece member is mounted between the cutout areas of the locking strips, even if the corner portion of the window frame is attached, the leg portion on the glass molding side is By engaging with the locking claws of the corner piece member, it is possible to prevent the molding from being inadvertently lifted up or a gap from being formed between the molding and the panel surface, thereby preventing the appearance from being impaired. There is.

"Problems to be solved by the invention" However, in this improved type fastener, since the corner piece member must be molded separately from the fastener body, the processed surface naturally becomes difficult. However, especially in actual use, apart from the work of fixing the strip-shaped base body of the fastener body to the vehicle body panel surface via the double-sided adhesive tape, a corner piece member is provided in the notch area of the locking strip of the fastener body. Since the work for mounting is required separately, there is a problem that the mounting work becomes very difficult.

Further, when the corner piece member is mounted in the cutout area of the fastener body, a pair of connecting leg pieces provided at both ends of the corner piece member is simply fitted between the strip-shaped base body and the locking strip piece. Therefore, when handling the fastener body or when inserting the legs on the molding side, there is a sufficient risk that the corner piece member may be displaced or fall out.
From this point as well, workability is regarded as a problem.

"Means for Solving the Problem" The present invention has been developed to effectively solve such a conventional problem, and provides a belt-shaped substrate fixed to a panel defining an automobile window frame. , Assuming a resin fastener integrally formed with a locking strip having a locking claw for locking the leg portion on the glass molding side, exhibiting a curved shape that matches the curved shape of the window frame corner portion, and A fastener main body having a shape in which a portion of the locking strip corresponding to the corner portion is cut out in advance is formed, and a locking claw is provided between the cut-out regions of the locking strip of the fastener main body to match the curved shape. The locking strips in the shape of
A configuration is adopted in which a portion having a bottom wall and a portion not having a bottom wall are alternately provided to the consecutively provided locking strip portions.

According to the "action", in the present invention, the strip-shaped base body is fixed to the panel surface defining the window frame, and the strip-shaped base body and the locking strip piece and the locking strip piece portions that are continuously provided from the rear side. , Just by inserting the legs on the glass molding side, even when installing the corner of the window frame,
Since the legs on the molding side can be locked to the locking claws on the locking strips, this locking causes the molding to inadvertently lift up from the corners, giving the appearance a good appearance. No worries about harm.

Moreover, according to the present invention, since the corner piece member and the like separately molded from the fastener body are not necessary at all, not only the improvement in processing can be expected in comparison with the conventional one, but the corner piece member is attached to the fastener body. Since the work to do it is completely unnecessary, the improvement of the work of attaching the glass molding can be expected greatly.

Moreover, in the present invention, since the locking strip portion is integrally connected to the notch area of the fastener body by insert molding, only the strip-shaped base body of the fastener body is fixed to the panel via the double-sided adhesive tape. Needless to say, this is especially the case when handling the fastener body or when inserting the legs on the molding side, as in the conventional case, where the locking strips are inadvertently displaced from the cutout area. No more worrying about falling out.

[Examples] Hereinafter, the present invention will be described in detail with reference to an illustrated example. The corner mounting fastener according to the example is also an integrally molded product of synthetic resin, and as shown in the figure, an automobile window frame is formed. A lip piece 3 that comes into contact with the folded curved surface of the panel is integrally formed on the upper end of the strip-shaped base 2 that is fixed to the panel to be formed, and a leg on the glass molding side is locked to the lower end of the strip-shaped base 2. It is premised that the locking strip 5 having the locking claw 4 is integrally raised.

In this embodiment, first, as shown in FIG.
Using a normal molding die (not shown), the portion of the strip-shaped substrate 2 corresponding to the window frame corner portion has a curved shape that matches the curved shape of the corner portion, and corresponds to the window frame corner portion. The fastener main body 1 having a form in which the locking strip 5 is cut out 6 in advance is molded. It should be noted that when the fastener body 1 is molded, as shown in the drawing, it is optional to form a slit 7 in the curved portion of the strip-shaped substrate 2 to promote bending.

Next, in the present embodiment, as shown in FIG. 2, the engagement between the cutout areas 6 of the locking strip 5 in the fastener body 1 is performed by insert molding using another molding die (not shown). A locking strip portion 9 having a shape that matches the curved shape of the corner portion and has a stop claw 8 is integrally provided afterward so that the locking strip 5 and the locking strip 5 are attached to the curved strip base body 2. It is characterized in that the locking strip portion 9 is continuously formed.

In this embodiment, when the locking strips 9 are continuously provided, as shown in FIGS. 3A and 3B, a portion having the bottom wall 10 and a portion not having the bottom wall 10 are alternately defined to form a bottom portion. The structure is such that the locking claws 8 for locking the legs on the molding side are formed only on the inner surface of the locking strip portion 9 that does not have the wall 10, but the present invention is restrained by this. Alternatively, the locking claw 8 may be formed to be continuous with the locking claw 4 of the locking strip 5 over the entire area.
It is optional depending on the implementation.

Therefore, using the fastener with the above configuration, the glass molding
In the case where 11 is attached to a corner portion of an automobile window frame, the strip-shaped substrate 2 is fixed to the surface of the panel 13 defining the window frame via the double-sided adhesive tape 12 as in the conventional case.

Then, regarding such fixation, at least the portion of the strip-shaped base body 2 corresponding to the window frame corner portion and the locking strip portion 9 have a shape that matches the curved shape of the corner portion. While easily following the shape of the corner,
The fastener can be securely fixed to the panel 13 surface in an ideal state.

Further, in such an operation, due to the existence of the portion having the bottom wall 10 provided on the locking strip portion 9, the bottom wall 10 is connected to the bottom wall on the side of the locking strip 5 and serves as a reference surface. Since the strip-shaped base body 2 of the fastener body 1 can be evenly fixed to the surface of the panel 13 while being brought into contact with the bottom portion of the panel 13, it is possible to ensure that the fastener is always fixed in the correct position even at the corner portion. Due to the presence of the part without the wall 10,
For example, even if there is some dimensional error between the curved shapes of the fastener body 1 side and the locking strip portion 9 side, this error is elastically absorbed at the portion not having the bottom wall 10 and the fastener is It is also possible to ensure that it adheres itself to the corners of the window frame very well.

Therefore, in the present embodiment, for example, when the locking strip piece 9 is continuously provided in the notch region 6, the clasp also has
There is no concern about wrinkles on the fastener side.

Therefore, this time, between the belt-shaped base 2, the locking strip 5 and the locking strip 9, the leg portion integrally provided on the glass molding 11 is provided.
When the leg 11a or a separate leg portion (not shown) is inserted, as shown in FIG. 4, the leg portion 11a of the molding 11 is not limited to the locking claws 4 of the locking strip 5 but also the locking strip piece. Since the locking claw 8 on the 9 side is also locked, the glass molding 11 can be reliably attached to the corner portion of the window frame with the state along the peripheral edge of the windshield glass G. .

Therefore, in the attached state using the fastener of the present embodiment, the glass molding 11 is also provided at the corner portion of the window frame.
Since the leg portion 11a of the mold 11 is surely locked to the locking claw 8 of the locking strip piece 9 that is continuously provided later, the molding 11 is inadvertently lifted from the fastener, and the molding 11 and the panel 13 surface are There is no need to worry about an undesired gap between the and, and the appearance will not be significantly impaired.Fix the fasteners with the double-sided adhesive tape 12, and insert the legs 11a of the molding 11 to install. Since the work is completed, workability is greatly improved compared to the conventional one.

Further, not only when the strip-shaped base body 2 of the fastener body 1 is fixed to the surface of the panel 13, but also when the leg portions 11a of the molding 11 are inserted, the locking strip portions 9 are continuously formed by insert molding. There is absolutely no concern that the locking strip portion 9 will be displaced or fall out within the cutout area 6.

It should be noted that in the structure in which the locking strip portions 9 are continuously provided by insert molding between the cutout regions 6 of the locking strip 5, it is undeniable that more or less connection lines are generated at these continuous locations, but the connection lines are It only occurs on the side of the locking strip 5 hidden by the molding 11 and never on the side of the strip-shaped substrate 2 including the lip piece 3 exposed to the outside, so that there is no concern that the presence of the connection line impairs the appearance. .

[Advantages of the Invention] As described above, the present invention adopts the above-described configuration, and does not force the use of an independent member such as a corner piece that is molded separately from the fastener body as in the conventional case, but the window frame corner. Since the legs on the molding side can be locked to the locking claws on the locking strips when the parts are attached, the moldings are inadvertently lifted up from the corners of the window frame and look No more worrying about damaging

In addition, in the present invention, since the locking strips are integrally connected to the notch area of the fastener body by insert molding, even if they are fixed to the panel side, the corners can be removed from the corners as usual. Without attaching the piece member to the notch area, it is only necessary to fix only the strip-shaped base body of the fastener body to the panel via the double-sided adhesive tape, which makes the work well, and when handling the fastener body. There is no need to worry about the locking strips accidentally shifting or falling off when the legs on the molding side are inserted.

Moreover, since the locking strip portion is alternately provided with the portion having the bottom wall and the portion not having the bottom wall, the panel serving as a reference surface is formed by connecting the bottom wall to the bottom wall on the side of the locking strip. While contacting the bottom of the, the fastener body can be uniformly fixed to the panel surface, and even if there is some dimensional error in the curved shape of the fastener body side and the locking strip portion side, This error can be elastically absorbed at a portion having no bottom wall, and the fastener itself can be extremely well followed and fixed to the corner portion of the window frame. From this point as well, improvement in workability is greatly promoted.
