JPS6387310A - Holder for automobile windshield pane - Google Patents

Abstract

PURPOSE:To aim at facilitating the insertion of a windshield pane and at stabilizing the support thereof, by forming a tapered groove in the upper edge section of the opening of a U-like groove in which the lower edge part of the windshield pane is adapted to be fitted, and by forming saw tooth-like concave and convex parts in the inner surfaces of the U-like groove. CONSTITUTION:An automobile windshield pane 1 is bonded at its lower edge by means of an adhesive 9 to a U-like groove 8 formed in the upper section of a holder 7 coupling between the windshield pane 1 and an elevating device for the latter. In this arrangement, a tapered surface 8a is formed in each upper edge part of the opening of the U-like groove so that the space between the tapered surfaces 8a is widened outward. Further, vertical V-like grooves 8a are successively formed in each inner surface of the U-like groove 8 so that a saw tooth-like concave and convex part 8c is formed in each inner surface of the U-like groove 8. The concave and convex parts 8c are made into contact with both surfaces of the windshield pane 1, and the adhesive 9 is filled in the V-like grooves 8b. With this arrangement, when the windshield pane 1 is inserted into the holder 7, the tapered surfaces 8a serve as a guide facilitating the introduction of the windshield pane 1, and the concave and convex parts 8 may supports the both surfaces of the windshield pane 1, stably over a wide range thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a holder that connects an automobile window glass and a lifting device that moves the window glass up and down.

[Prior Art] A conventional automobile window glass holder will be explained based on FIGS. 5 to 7.

FIG. 5 is a schematic diagram of a windowpane 1 of an automobile (not shown) and a lifting device 2 for moving the windowpane 1 up and down. In FIG. The main arm consists of a driving arm 4a and a driven arm 4b which are pivotally connected to each other by a bin 3, and a horizontal guide channel 6 which is loosely fitted and supported by rollers 5, 5 which are pivotally connected to the upper ends of both arms 4a and 4b. 4a and the driven arm 4b by appropriate driving means (
This is a well-known structure in which the guide channel 6 is rotated about the bin 3 by a screw (not shown), thereby moving the guide channel 6 up and down while keeping it in a horizontal state. This elevating device 2 and the window glass 1 are connected by a holder 7 made of synthetic resin. The holder 7 has a U-groove 8 formed in its upper part, and an adhesive 9 is applied to the U-groove 8 to fit and adhere to the lower edge of the window glass 1. On the other hand, a mounting plate 10 is vertically installed at the bottom of the holder 7, and a bolt 12 inserted from the guide channel 6 of the lifting device 2 is screwed into a nut 11 embedded in the mounting plate IO to connect the two together. are doing.

However, in the holder 7 described above, there is a problem in the bonding strength between the synthetic resin that is the material of the holder 7 and the adhesive, so in order to solve this problem, thin irregularities are formed on the inner surface of the U groove 8. Japanese Utility Model Publication No. 53-25931 discloses a structure in which the surface is not roughened and protrusions 8' are formed at both ends of the U-groove 8 to prevent the adhesive 9 from extruding.

[Problems to be Solved by the Invention] According to the above-mentioned prior art, (a) the adhesive 9 is attached to the inner surface of the holder 7 by the convex strip 8';
Since the space in which the coating is applied is wide, the window glass 1 is supported only by the protruding strips 8', and there is a problem that the window glass 1 cannot be stably held.

(b) Since the contact surface of the convex strip 8' with the window glass l is a flat surface, the frictional resistance when inserting the window glass 1 into the holder 7 is large, so that the window glass 1 does not fit into the U groove 8 of the holder 7.
is difficult to fit.

(c) Although fine irregularities are formed in the U-groove 8 to improve bonding with the adhesive 9, it is still insufficient because the contact area between the adhesive 9 and the U-groove 8 is small.

It had the following problems.

[Means for Solving the Problems] Therefore, the present invention forms a taper 8a that widens outward on the upper edge of the opening of the U-groove 8 of the holder 7, and also forms a taper 8a on the inner surface of the U-groove 8 in the vertical direction. The V-shaped grooves 8b, 8b, .
c, 8c are brought into contact with one surface of the window glass, and the V-shaped groove 8b.

8b... is filled with adhesive 9.

[The taper 8a formed at the upper edge of the opening of the U-groove 8 of the working co-holder 7 acts as a guide, making it easier to insert the window glass 1, and the uneven surfaces 8c, 8c on the inner surface of the U-groove 8 are serrated. The contact portion with the window glass 1 is a line contact of the chevron-shaped top, which reduces frictional resistance and facilitates insertion of the window glass 1.

In addition, since the serrated uneven surfaces 8c and 8c support one side of the window glass over a wide range, the stability of the window glass l is high.
Furthermore, since the adhesive 9 is filled in the V-shaped grooves 8b, 8b, . . . , the contact area between the adhesive 9 and the U-groove 8 can be increased, and a sufficient bonding force can be obtained.

[Example] Figures 1 to 4 show an example of the present invention.
As mentioned above, the holder 7 has a U groove 8. Taper 8a on the upper edge of the opening + V-shaped groove 8b, 8b..., uneven surface 8c,
8c and a mounting plate 1O, the whole is made of synthetic resin material such as polyacetal mixed with glass fiber and adhesive 9.
It is made of a material that has improved bonding properties. On both sides of the lower end of the U-groove 8, protruding step portions 8d and 8cl are provided to form a recessed portion 8e, and by filling the recessed portion 8e with adhesive 9, the lower edge of the window glass 1 is also bonded. I have to.

The mounting plate 10 installed vertically at the bottom of the holder 7 has an oak)-1
1 is buried, but the nut 11 has a cylindrical body 13 protruding from the surface facing the guide channel 6, and the cylindrical body 13
The upper surface of the mounting plate 10 is made to be the same as or slightly protrude from the surface of the mounting plate 10 to prevent the mounting plate 10 from being crushed by tightening with the bolts 12.

When inserting the window glass l into the holder 7, an appropriate amount of adhesive 9 (urethane) is first filled into the V-shaped grooves 8b, 8b, . . . of the uneven surfaces 8c, 8c.

Next, the window glass 1 is inserted from the upper edge of the opening of the U groove 8 of the holder 7. At this time, the taper 8a allows the window glass 1 to be inserted easily, and the uneven surfaces 8c, 8c have chevron-shaped tops that allow the window glass 1 to be inserted easily. Since it is supported in a line-contact manner, it is easy to slip and can be pushed in easily.

[Effects of the Invention] As explained above, according to the holder 7 of the present invention, the window glass 1 can be easily inserted due to the taper 8a on the upper edge of the opening formed in the U-groove 8 and the serrated uneven surfaces 8c, 8c. And it can be done quickly.

In addition, since the adhesive 9 is filled in the V-shaped grooves 8b, 8b, etc., the contact area between the adhesive 9 and the inner surface of the U-groove 8 increases, and the bonding force increases. Since the window glass 1 is supported by the entire U groove 8 by the uneven surfaces 8c, 8c, the window glass can be kept stably, and the window glass 1 can be held stably and reliably for a long period of time. .
