Abstract

PURPOSE:To firmly fix a decorative member to the peripheral edge of a glass plane to eliminate the phenomenon of sound generation, by providing a holding member composed of a locking means for securing a decorative member and a sound absorbing member utilizing a tongue piece part at the terminal end of the holding member. CONSTITUTION:A holding member 15 is composed of a thin-wall base plate part 16, a tongue piece part 17, ridge pieces 18 and a tail end part 19. When a decorative member 10 is forced to be inserted into a sealant adhesive 23 with its locking part 14 at its front end being directed inward, and simultaneously, one end of locking pieces 13, 13 is engaged with the end peripheral face 22a of a glass pane 22 while the other end thereof is engaged with the ridge pieces 18 so that the decorative member 10 is held in a space 25. Due to such a fitness that the locking pieces 13, 13 are inclined outward, the decorative member 10 offers no projecting phenomenon while the molding part 11 thereof is pressed against the outer surface of the tongue part 17. Further, since the tongue part 17 is made of soft materials to prevent any gap from being formed, thereby it is possible to prevent air stream.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a holding structure for a window molding that is attached for decoration to the periphery of a window frame of a vehicle body.

[Technical background of the invention]

Generally, a window molding is attached to the periphery of a window frame of an automobile body via a fastener in order to cover the gap between the glass and the vehicle body.

For example, as disclosed in Utility Model Application Publication No. 53-72324,
The figure shows an example of this, in which a glass 7 is adhered to the periphery of the window frame of the car body using an adhesive 6, and then a long main body 2 is attached to the surface of the car body panel corresponding to the periphery of the glass using an adhesive tape 4, and then a clip is attached. This is a configuration in which the molding 1 is attached via a support 3.

However, in such a configuration, the tip 2a of the main body 2 and the molding 1
Due to the gap between the contacts 6, a high-pitched sound was generated when the car was running at high speed, resulting in a so-called whistling phenomenon.

Further, in this configuration, the molding 1 is attached using three parts, the main body 2 and the support body 3, which requires a large number of assembly steps and is undeniably expensive.

On the other hand, Japanese Patent Application Laid-Open No. 56-79019 reduces the number of parts as shown in FIG. It has been proposed to fix the lip 4' and the anchor part 3 of the leg 2 by configuring the lip 4'.

However, with this configuration, since the lip 4' protrudes toward the inner surface, a problem arises in the adhesion effect, and the fixing of the wind molding 1 itself lacks stability.

JP-A-56-157614 solves these drawbacks by attaching a molding 1 having a locking piece 2 as shown in FIG. 6 to a retaining projection 4' of a tape 3' attached with double-sided adhesive tape.
or by tilting the peripheral edge 6 of the glass 5; l) By bringing the locking piece 2 into contact with the glass 5, an effect of preventing removal is obtained; This was to fix it.

However, even with this configuration, a so-called whistling phenomenon occurs during high-speed operation due to the gap between the edge of the molding 1 and the tape tip 3a', which causes discomfort to the driver.

[Purpose of the invention]

The present invention was devised in view of the above-mentioned drawbacks, and an object of the present invention is to provide an automobile window molding holding structure that has good adhesion and is capable of controlling generated noise.

[Structure of the invention]

In order to achieve such an object, the present invention comprises a decorative body and a holding body, and the holding body has a locking means for fixing the decorative body in a predetermined position, and a raised tongue at the end. A piece part is provided.

[Embodiments of the invention]

The invention will be described in detail below based on embodiments shown in the accompanying drawings.

FIG. 1 shows an embodiment of the present invention, and a decorative body 10 constituting a shielded molding according to this embodiment is as shown in FIG. taJ.
A molded part made of synthetic resin has a molding part 11 having the same wall thickness and a curved shape, a leg part 12 vertically connected from the center of the inner surface of the molding part 11, and the upper and lower surfaces of the leg part 12. There are a plurality of locking pieces 13, 13 curvedly inclined in the direction of the molding part 11, and a triangular stop part 14 with a pointed tip at the end of the leg part 12. Become.

On the other hand, Figure tb+ shows a holder 16 made of the same synthetic resin material.
, the holder 16 includes a thin base plate 16 having a constant width and an elongated shape, a tongue piece 17 connected to the front end of the base plate 16 in an inclined manner, A plurality of protruding strips 18 serving as locking means are formed on one side of the base plate part 16 at the same width intervals in the length direction, and an end whose arm is bent in the same direction as the other terminal protruding strip 18 of the base plate part 16. It is composed of a tail section 19.

Note that 2o is a double-sided adhesive tape for bonding the substrate portion 16 to the panel surface 21.

FIGS. 2 to 3 are diagrams for explaining the operation. First, a long holding body 15 is molded using an extrusion molding machine, and then cut to a predetermined length around the periphery of an automobile window frame.

A double-sided adhesive tape 20 is adhered to the back surface of the cut holder 15, and the entire circumference is adhered to a panel 21 at the periphery of the window frame.

After this adhesion, apply 1ikN of sealant adhesive 23 uniformly attached to the inner periphery of the glass 22 until the panel rises.
Press it and glue it to the window frame.

The sealant adhesive 23 flows to some extent until it hardens, and the flowed part comes into contact with the end and tail portions 19 of the substrate portion 16, and assists the adhesive force of the adhesive tape 20 on the substrate portion 16 itself via the curved end and tail portions 19. It will be fixed immovably.

Note that 24 is a dumb rubber.

As a result, a constant space 25 is formed between the glass 22 and the holder 15 around the entire circumference.

FIG. 3 is an explanatory view of the decorative body 1o inserted into the space 25. When the decorative body 1o is forcibly inserted with the stop portion 14 at the tip inward against the sealant adhesive 23, the locking piece 13. 1
3 is fitted to the end circumferential surface 22a of the glass 22 and the other to the protruding strip 18, thereby attaching the decorative body 1o to the space 25.

As shown in the figure, the decorative body 1o has locking pieces 13, 13...
At the same time, the outward protrusion phenomenon caused by the outward inclination of the fitting is eliminated, and at the same time, the molding part 11 presses into contact with the surface of the tongue part 17, and the tongue part 17 becomes a soft body. Because of this, an elastic contact force is generated between the molding part 11 and the molding part 11, so that no gap is generated and air circulation can be prevented, and the air flow from the housing can be directed toward the molding part 11. can.

〔Effect of the invention〕

As described above, the automobile window molding holding structure according to the present invention includes a decorative body that increases the distance between the glass periphery fixed to the car body window frame and the car body, and a holder bonded to the car body surface at the window frame periphery. Furthermore, the holder is configured to include a locking means for fixing the decorative body in a predetermined position and a soundproofing means using a tongue piece of the terminal, so that the decorative body can be immovably attached to the periphery of the glass. The tongue piece part 17 was able to be fixed to the
Due to the existence of this, it was possible to eliminate the whistling phenomenon, that is, the vocalization phenomenon even during high-speed driving.

Further, the fixing of the decorative body can be easily completed by simply pressing and inserting the decorative body, and even when disassembling the decorative body for repair or the like, it can be removed without requiring relatively many man-hours, which is useful for mass production.
