Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated glass obtained by superposing an outer glass and an inner glass with an intermediate film interposed therebetween and having a fitting for mounting to other members.

[0002]

2. Description of the Related Art DPG (Dot Point Glaz) in which holes are made in a glass plate and attached to a body or the like with bolts and nuts
The laminated glass used in the ing method is equipped with a fitting made of a fitting nut and a fitting bolt. Conventional examples of this mounting bracket are shown in FIGS.

A laminated glass having a mounting member shown in FIG. 4 is laminated by interposing an intermediate film 103 made of a thermoplastic resin such as a polyvinyl butyral (PVB) film between an outer glass 101 and an inner glass 102 and joining them by roll-to-roll bonding. Glass 100 is manufactured, and this laminated glass 100 is manufactured.
A hole 102a is formed in the inner glass 102 of the
The resin spacer 105 is fitted into a and the outer glass 1
01 also has a hole 101a, and a head 106a of a fitting bolt 106 penetrating the resin spacer 105 is held in the hole 101a through a retaining member 104, and a fitting nut 107 is screwed into the fitting bolt 106 from the indoor side. are doing.

In the laminated glass having the fitting shown in FIG. 5, a large diameter hole 109 is provided in the outer glass 101 of the laminated glass manufactured by roll matching, and the head 106a of the fitting bolt 106 is sealed in the large diameter hole 109. It is inserted through the material 110, and the shaft portion 106b is inserted into the inner glass 102.
And a fitting nut 107 is screwed into the fitting bolt 106 from the indoor side.

In the laminated glass having the mounting bracket shown in FIG. 6, a hole 102a for holding the head portion 106a of the fitting bolt 106 is formed in the inner glass 102, and this hole 1
02a holds the head portion 106a of the fitting bolt 106 via a retaining member 111, and a fitting nut 107 is screwed onto the thread portion of the fitting bolt 106.

[0006]

However, the above-mentioned conventional example has the following problems. In the laminated glass shown in FIGS. 4 and 5, the laminated glass is manufactured by roll-matching, so that it is a condition that a part of the fitting is not projected from the glass when the roll-matching is performed. As a result, after manufacturing the laminated glass, it is necessary to make holes in the outer glass or the inner glass with an accurate depth, and the work is troublesome. In order to make it uniform, it is necessary to work through the intermediate film at the hole.

On the other hand, in the laminated glass shown in FIG. 6, since the laminated glass is manufactured by a method of placing it in a vacuum bag and heating it in an autoclave, it does not matter if a part of the fitting is projected from the glass in advance. Inferior in mass productivity, and pressure is not applied around the bolts, making it difficult for bubbles to escape.

[0008]

In order to solve the above-mentioned problems, the present invention is a laminated glass obtained by superposing an outer glass and an inner glass through an intermediate film, which is equipped with a mounting bracket. The fitting is composed of a fitting nut that is fitted into the hole formed in the inner glass and a fitting bolt that is screwed into the fitting nut from the inside, and the fitting nut has a rotation that prevents co-rotation when the fitting bolt is screwed. Forming a stop hole,
The fitting bolt was formed with a jig insertion hole extending to the attachment portion and the rotation stop hole.

Here, the jig insertion hole may be formed so as to axially penetrate the fitting portion of the fitting bolt.

[0010]

A fitting nut is fitted in advance on the inner glass, and in this state, the inner glass and the outer glass are joined together by roll alignment through the intermediate film. Then, after manufacturing the laminated glass, a fitting bolt is screwed into the fitting nut while preventing both of them from turning together to complete a fitting, and the fitting is fixed to the body or the like through the fitting.

0 and the fastener 60 are used. The hexagon wrench 50 has a shaft portion 50a having a diameter slightly smaller than the jig insertion hole 30h, a hexagonal column portion 50b engageable with the hexagonal hole 10d formed at the tip of the shaft portion 50a, and a rear end of the shaft portion 50a. The holding part 50c is provided. Further, the fastener 60 is a protrusion 60 corresponding to the small holes 30f and 30g of the fitting bolt 30.
For example, it is a fork (not shown) having a and 60b formed at one end.

First, the inner glass 2 is pre-drilled, a bush 20 is fitted into this hole, the fitting nut 10 is attached to the inner glass 2 through this bush 20, and polyvinyl butyral (PV) is placed on the outer glass 3.
B) The inner glass 2 is polymerized by roll alignment on the intermediate film 4 such as a film (see FIG. 2A).

Next, the fitting bolt 30 is screwed into the fitting nut 10. At that time, the jig insertion hole 3
The shaft portion 50a of the hexagon wrench 50 is inserted through 0h, and the hexagonal column portion 50b at the tip thereof is inserted into the fitting nut 10.

Thereafter, the projection 60 formed on the fastener 60
a and 60b are small holes 30f of the fitting bolt 30,
The fitting bolt 30 is fastened and fixed by rotating the fastener 60 while engaging the hexagonal column portion 50b with the hexagonal column portion 50b (see FIG. 2C).

FIG. 3 is a cross-sectional view showing a state in which a mounting bracket is attached to the laminated glass, and shows a state in which the hexagon wrench and the fastener used for mounting are removed from the mounting bracket after the completion of tightening in FIG. . With such a configuration, the laminated glass can be fixed to the body or the like via the mounting metal fitting (mounting portion 30b).

[0020]

The present invention has the following effects due to the above configuration. Claim 1 is a laminated glass obtained by superposing an outer glass and an inner glass via an intermediate film, and is provided with a fitting, wherein the fitting is fitted in a hole formed in the inner glass. And a fitting bolt that is screwed into the fitting nut from the inside.A rotation stop hole is formed in the fitting nut to prevent co-rotation when the fitting bolt is screwed, and the fitting bolt has a mounting portion and the rotation stop. Since the jig insertion hole that reaches the hole is formed, the fitting nut that constitutes the mounting bracket does not protrude from the glass and it is possible to perform roll alignment, and after the laminated glass is manufactured, punching processing and hollowing the interlayer film of the hole part are possible. It becomes unnecessary. Therefore, mass production is possible, and there is no risk of water leakage because the bolt head is not exposed to the outside.

According to a second aspect of the present invention, since the jig insertion hole is formed so as to penetrate in the axial direction of the fitting portion of the fitting bolt, the jig is engaged with the rotation stopping hole through the hole, whereby the fitting accompanying tightening of the fitting bolt is performed. Rotation of the nut is prevented and bolts can be tightened easily and reliably.
