Description

[Detailed Description of the Invention] This invention relates to a glass plate fixing device for fixing a glass plate to a frame in a buffered and waterproof condition.

In the conventional glass plate fixing device, as shown in FIG.
For example, it is fixed to the plate-shaped frame 3 that constitutes the housing.

That is, the rubber bushing 2 is inserted so that the inner peripheral edge of the frame 3 is inserted into the groove formed on the outer periphery of the rubber bushing 2.
is attached to the frame 3, and the rubber bushing 2 is deformed and acidified so that the concave groove formed at the top of the inner surface of the rubber bushing 2 is reduced, so that the glass plate 1 is inserted into the groove formed on the inner circumference of the rubber bushing 2. The glass plate 1 is held so that the outer peripheral edge is inserted, and an attached bushing 2a is inserted into the recess of the rubber bushing 2 to prevent its reduction and deformation, thereby fixing the glass plate 1. That's what I do.

However, in the glass plate fixing device configured as described above, the outer surface side portion of the rubber bushing 2 protrudes from the glass plate 1, so when an object should be placed in close contact with the outer surface of the glass plate 1. In this case, the size of the object is restricted to be smaller than the exposed outer surface of the glass plate 1, and when the outer surface of the glass plate 1 is used as a work surface, the protruding portion of the rubber bushing 2 may become an obstacle. There were drawbacks.

The object of this invention is to provide a glass plate fixing device which can fix a glass plate to a frame without leaving any part protruding from the outer surface of the glass plate, while eliminating the above-mentioned drawbacks.

An embodiment of this invention will be described below with reference to the drawings.

In this invention, as shown in FIG. 2, a rubber ring 4 is elastically fitted onto the outer peripheral surface of the glass plate 1.

That is, the inner diameter of the rubber ring 4 is made slightly smaller than the outer diameter of the glass plate 1, and the rubber ring 4 is expanded and attached to the outer peripheral surface of the glass plate 1 by its elasticity.

It is preferable that the rubber ring 4 is provided with a protruding edge 4a that is brought into close contact with the inner peripheral edge of the glass plate 1.

On the other hand, the inner circumferential surface of the frame 3 to which the glass plate 1 is to be fixed is bored from the inner side along the inner circumferential edge, and a rubber ring support part 3a with a predetermined thickness remains on the outer surface side. A stepped portion 6 is formed, and the rubber ring 4 is positioned within this stepped portion 6.

Here, the depth of the stepped portion 6 in the thickness direction is slightly smaller than the thickness of the rubber ring 4.

Then, an inner peripheral portion of a ring-shaped metal plate 5 fixed on the inner surface of the frame body 3 with a screw 7 is brought into contact with an exposed surface of the rubber ring 4 facing in the same direction as the inner surface of the frame body 3, Tighten the screws 7 to close and fix the metal plate 5 to the frame 3, and at the same time, tighten the metal plate 5 and the bottom surface of the step 6, that is, the rubber ring holding portion 3a of the frame 3 remaining due to the formation of the step 6. The rubber ring 4 is pressed between the inner surface and the inner surface.

Since this invention has the above structure, the glass plate 1 is not only held by the rubber ring 4 due to its elasticity, but also the tip of the rubber ring 4 is held thick by the rubber ring holding part 3a and the ring-shaped metal plate 5. Since the glass is held in the horizontal direction, its inner circumferential surface is deformed inwardly and its outer circumferential surface is displaced outwardly, and the outer circumferential surface is in contact with the inner circumferential surface of the stepped portion 6. The plate 1 is held very firmly by the rubber ring 4, and a waterproof effect is reliably obtained.

Of course, since the rubber ring 4 is the only thing that directly holds the glass plate 1, it is supported in a sufficiently buffered state.

These effects are further enhanced by the protruding edge 4a of the rubber ring 4.

Furthermore, according to this invention, since there is no protrusion on the outer surface of the glass plate 1, the outer surface of the glass plate 1 can be made to match the outer surface level of the frame 3 to form a large flat surface. It is possible to place an object larger than the glass plate 1 so that the required part is in close contact with the outer surface of the glass plate 1, and there is no obstacle to using the flat surface including the glass plate 1 as a work surface. , the required work can be done efficiently.

As described above, according to this invention, the glass plate can be fixed to the frame body with an extremely simple structure without any objects protruding from its outer surface, and the glass plate can be firmly fixed using the rubber ring. It can be retained and has great effects such as complete waterproofing.
