Abstract

PROBLEM TO BE SOLVED: To surely prevent a holding frame from falling from the circumferential edge of a glass panel by a small amount of an adhesive, without damaging the appearance of the glass panel on which the holding frame is mounted. SOLUTION: Contacting pieces 6 that contact elastically, entirely a circumferential edge serially from the thickness direction are provided on a holding frame B furnished with a groove into which the circumferential edge of a glass panel A is fitted entirely, in the direction of contact in accordance with the surface and the reverse of the circumferential edge. And an adhesive E adhering the circumferential edge to the holding frame B is filled into the groove side rather than the contacting pieces 6 so that filled portions and non-filled portions may be formed along the groove.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding frame provided with a concave groove into which a peripheral portion of a glass panel is fitted over the entire periphery. The present invention relates to a glass panel holding structure in which contact pieces elastically contacting with each other protrude in the contact direction in correspondence with the front and back surfaces of the peripheral portion.

[0002]

2. Description of the Related Art In the above-mentioned structure for holding a glass panel, a holding frame is mounted around the entire periphery of the glass panel so that the glass panel can be mounted on a sash or the like without rattling. In addition, a contact piece that elastically adheres to the peripheral portion is provided to prevent water from entering between the peripheral portion and the holding frame.

[0003] Conventionally, in order to prevent the holding frame from dropping off from the peripheral edge, the holding frame and the peripheral edge are not integrally fixed but the end of the holding frame into which the peripheral edge is fitted. The falling off is prevented by adhering each other and connecting the holding frame body whose peripheral edge is fitted over the entire circumference in a series of rings, but the holding frame body is handled during handling such as carrying work. However, there is a disadvantage that the holding frame body is likely to come off from the peripheral edge portion due to deformation or displacement.

Therefore, in order to solve this drawback, as shown in FIG. 7, the holding frame B and the peripheral portion of the glass panel A are bonded to prevent the holding frame B from falling off from the peripheral portion. There has been proposed a glass panel holding structure as described above.

[0005] In this holding structure, a contact piece 6 elastically closely contacting the peripheral portion from the thickness direction over the entire periphery in a continuous manner is provided so as to correspond to each of the front and back surfaces of the peripheral portion. 6
The holding frame B and the peripheral portion are bonded to each other with an adhesive E that is continuously filled over the entire periphery of the peripheral portion between the peripheral portion on the concave groove portion 4 side and the holding frame B.

[0006]

When the holding frame B and the peripheral edge of the glass panel A are bonded as described above, the holding frame B is hard to be detached from the peripheral edge, but the entire circumference of the peripheral edge is prevented. Since the adhesive E is filled as shown in FIG. 7A, not only a large amount of the adhesive E is required but also the adhesive E
If the filling amount is too large, as shown in FIG. 7B, the excess adhesive E protrudes from between the contact piece 6 and the peripheral portion,
The appearance of the glass panel A to which the holding frame B is attached may be impaired.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and does not impair the appearance of a glass panel on which a holding frame is mounted, and uses a smaller amount of adhesive than in the past, and uses a holding frame from the peripheral edge thereof. An object of the present invention is to reliably prevent the body from falling off.

[0008]

The feature of the glass panel holding structure according to the present invention resides in that the peripheral edge and the holding frame are arranged closer to the concave groove than the close contact piece and to the concave groove. Along with an adhesive filled so as to form a filled portion and a non-filled portion along.

That is, an adhesive-filled portion and a non-filled portion are formed on the concave groove side of the close contact piece, and the peripheral portion of the glass panel is filled with the adhesive filled while the amount of the adhesive filled is reduced. In particular, as the periphery of the glass panel is fitted into the filling portion, the adhesive of the filling portion spreads to the non-filling portion side, and the adhesive is elastically bonded to the elastic piece and the glass. There is no danger of protruding from between the periphery of the panel.

Therefore, it is possible to reliably prevent the holding frame from falling off from the peripheral edge thereof with a smaller amount of adhesive than before, without impairing the appearance of the glass panel on which the holding frame is mounted.

If a drain hole is formed at a position corresponding to the concave groove of the holding frame, if the adhesive is filled while avoiding the position where the drain hole is formed, the adhesive may be formed inside the concave groove. Even if water invades, the water is easy to come out of the drain hole,
It is possible to prevent a situation in which the appearance is impaired by a mold or the like that has propagated due to the water staying inside the concave portion, or the holding frame is damaged at an early stage.

[0012] The characteristic structure of the holding structure of the glass panel according to the present invention is characterized in that the adhesive is provided at least in the concave groove at the corner of the holding frame body bent along the plate surface of the glass panel. The point is that it is filled.

That is, when the holding frame expands and contracts due to a change in temperature, at the corners bent along the plate surface of the glass panel, the holding frames press and pull against each other with respect to the peripheral edge of the glass panel. The relative displacement is repeated, and as a result, the degree of adhesion between the peripheral portion and the contact piece is easily loosened, but at least, the adhesive is filled in the concave groove portion of such a corner portion, and the peripheral portion and the holding frame body are To prevent relative displacement between the peripheral portion and the holding frame, so that the degree of adhesion between the peripheral portion and the contact piece is not easily loosened.

Accordingly, at the corners bent along the plate surface of the glass panel, it is difficult for water to enter the inside of the concave groove portion, and the appearance of a mold or the like propagated due to the water entering the inside of the concave groove portion. Can be prevented or the holding frame can be damaged at an early stage.

According to a third aspect of the present invention, there is provided a glass panel holding structure, wherein the contact pieces are spaced from each other in a circumferential direction with respect to the peripheral edge portion and in a depth direction of the concave groove portion. A first elastic piece and a second elastic piece that are elastically in contact with each other with a gap therebetween, and the adhesive is provided between the first elastic piece and the second elastic piece in a depth of the concave groove portion. The point is that it is filled further inward than the second elastic piece provided on the side.

That is, when a single elastic piece is provided as a close contact piece and the adhesive is filled on the concave groove side of the elastic piece,
The deformation range of the elastic piece may be restricted by the hardened or solidified adhesive, and it may not be possible to effectively prevent water from entering the inside of the concave groove portion. The pieces are arranged side by side with an interval, and the adhesive is filled on the concave groove side than the second elastic piece, so even if the deformation range of the second elastic piece is regulated by the hardened or solidified adhesive, The first elastic piece whose deformation range is not restricted can ensure close contact with the peripheral portion.

Therefore, water can be effectively prevented from entering the inside of the concave portion over the entire periphery of the peripheral portion of the glass panel.
