Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to the peripheral edge of a window frame for a vehicle, and attempts to cover the outer peripheral edge of the window glass adhered to the window frame with a decorative molding. Regarding the molding holding mechanism for holding and fixing the molding,
In particular, this invention relates to a holding structure that can be applied to window frames in which the outer peripheral edges of the left and right sides of a vehicle window frame are not of uniform height, but gradually increase in height toward the bottom. .

``Prior Art'' Generally, a fastener 2 made of rubber, synthetic resin, etc. is adhered to the outer peripheral edge 1a of a vehicle window frame 1 using double-sided adhesive tape 3, as shown in FIG. By engaging a desired plurality of clips 5... in the groove 4 and locking the molding 6 to the molding holding portion 5a of the clip,
A window glass 8 adhered to the inner circumferential plane portion 1b of the vehicle window frame 1 with an adhesive 7, and the fastener 2
The molding 6 is used to close and cover the space between the board part 2a and the board part 2a.
(see publication).

However, the outer peripheral edge 1a of the vehicle window frame 1 is normally formed at a uniform height over the entire circumference of the frame 1, so in such a case, If a fastener having a uniform height in the longitudinal direction is used, continuous extrusion molding of such a fastener is easy and mass production is possible.

``Problem to be Solved by the Invention'' However, when using the wiper, it is necessary to prevent the rainwater wiped outward by the wiper from scattering as water droplets to the side of the car and obstructing the visibility of the side window. In addition, during high-speed operation, the air flow becomes smooth toward the ceiling along the shield glass, and due to requests such as trying to prevent an increase in air resistance as much as possible, the outer peripheral side as shown in Figure 1 is The height of the edge portion 1a from the inner circumferential plane portion 1b is on the left and right sides of the window frame 1, and the height gradually changes along the lengthwise direction, e.g., increasing from the top to the bottom. The third mall as Mall 6
As clearly shown in the figure (b), a structure whose height gradually increases along the longitudinal direction is sometimes used.

Therefore, when the outer circumferential edge 1a is formed at a non-uniform height as described above, instead of using a fastener of uniform height, the fastener is made to match the height of the outer circumferential edge 1a as shown in FIG. It is conceivable to adopt one in which the height is gradually changed in the direction.

However, such a fastener 2' cannot be formed as a continuous band-like body as in the case of uniform height, and it is necessary to form each fastener with a predetermined taper and a predetermined length. This makes it impossible to provide a molding holding structure suitable for the window frame 1 at a low cost.

It is an object of the present invention to provide a holding mechanism that can solve the above-mentioned problems.

``Example'' The present invention will be described in detail with reference to Examples shown in FIG. Unlike the aforementioned fastener 2', the fastener 2 is formed to have a uniform height, and the height is
The inner peripheral plane part of the outer peripheral side edge part at the upper end of the tapered outer peripheral side edge part 1a that is upright and curved from the inner peripheral flat part 1b to which the window glass 8 of the vehicle window frame 1 is bonded. The fastener 2 has its base plate 2a aligned with the height W of the lower end 1c, and the fastener 2 is attached with double-sided adhesive tape along the front edge 1a' of the outer peripheral edge 1a on the outside of the vehicle. 3 to the ipsilateral edge 1a.

Here, in the fastener 2, a locking groove 4 is formed between a bent part 2b which is bent back from the tip edge of the base plate part 2a and the base part 2a, and 2c in the figure is a curved part 2b. A locking protrusion protruding into the groove 4 from the inner surface of the portion 2b is shown.

Next, in the locking groove 4 of the fastener 2 bonded as described above, a desired plurality of different types are formed so that both the height and the width gradually increase from the upper side to the lower side. The dimensions of the clips 5, 15, 25, 35... are A ₁ ,

Here, A, B, and C in Figure 5 are A _{1 and C} in Figure 4, respectively.
The cross section at A ₃ and A ₄ is shown, and the clips 25 and 35 engaged at A ₃ and A ₄ are as follows:
Stable support arms 25c, 35c are provided to protrude from the center portions of the molding locking portions 25a, 35a toward the inner peripheral plane portion 1b.

Next, in the case of the fastener 12 shown in FIG. 6, an engaging protrusion 9 is provided protruding from the curved portion 12b toward the inner circumferential plane portion 1b, and the fastener 12 is attached to the outer circumferential edge 1a. In order to bond the above, only the upper engaging protrusion 9, where the height of the separating portion 1d is small and the engaging protrusion 9 and the inner circumferential plane portion 1b will collide with each other during adhesion, is prepared in advance. Cut out the bent part 12b of the fastener 12 as shown in the figure.
In the spaced apart portion 1d between the inner peripheral plane portion 1b and the inner peripheral plane portion 1b,
The engagement protrusion 9 is left only on the lower side, which is large enough to accommodate the engagement protrusion 9.

As shown in FIG. 6, at the A ₃ and A ₄ positions, auxiliary engagers 10 and 10' having heights corresponding to the heights of the separating portions 1d at those positions are provided.
