Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in multi-layer glass in which a film-like material is interposed between the glasses.

2. Description of the Related Art Double-layer glass is known in which a transparent heat ray reflecting plate or film is interposed between a pair of glasses that are spaced apart from each other to provide a heat insulating effect. By the way, in such double-layer glass, especially those using a film-like material such as a transparent heat ray reflective film, it is necessary to fix the edges of the film-like material between the glass sheets, but conventionally, glass is assembled into a multi-layered glass. Because the film was attached using a method such as clamping it at the same time as it was attached, it was not possible to stretch it sufficiently, and wrinkles were likely to occur on the surface of the film. It was hot.

The present invention aims to eliminate such drawbacks, and its purpose is to improve the appearance of double-layered glass in which a film-like material is interposed between the glasses, especially by preventing wrinkles in the film-like material. Furthermore, it is an object of the present invention to provide double-layer glass that can improve marketability.

In order to achieve the above object, the present invention involves attaching a film-like material to a rod-shaped support frame with a U-shaped cross section, extending uniformly in the vertical and horizontal directions, and attaching this support frame to a rod-shaped support frame with a U-shaped cross section. It is fitted into a positioning shape formed on a spacer member for glass bonding interposed therebetween, and the direction of this fitting is the direction in which the film-like body is stretched;
In addition, the end portion of the film-like body is assembled so as to be sandwiched between the support frame body and the spacer member, so that uniform stretching tension can be applied to the end portion of the film-like body so that the film-like body can be stretched. It is characterized by the following.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. First, a first embodiment of the present invention will be described with reference to FIG. This figure shows a cross-sectional view of the main parts of double-layer glass.

It is assumed that the double-layer glass indicated by the reference numeral 1 in the figure is, for example, rectangular as a whole and is window glass for a building. This double-layer glass 1 has a pair of glass plates 2 and 3 on both sides separated by a predetermined width and facing each other in parallel planes. A spacer member 4 is interposed at the end between each glass plate 2 and 3 slightly inside the end of the glass, and a sealing material 5 is further filled from the outside of the spacer member 4 to the end of the glass. As shown in FIG. 1, the spacer member 4 includes a horizontal lower surface 4a, inclined surfaces 4b and 4c that are inclined upward from both sides thereof, and side surfaces 4d and 4e that are perpendicular upward from both ends of these inclined surfaces 4b and 4c and contact each glass surface. This side 4d, 4
Bend inward from e, one horizontal upper half surface 4f, the other slightly upwardly inclined upper half surface 4g, and fold each inner end of this upper half surface 4f and upper inclined half surface 4g downward at approximately the center between the glasses. End abutment surface 4 that bends and abuts
h, 4i. Therefore, the upper half surface 4f
A step surface 4j is formed between the step surface 4j, the upper half surface 4f, and the inner surface of the glass 2, and a recess formed by the step surface 4j, the upper half surface 4f, and the inner surface of the glass 2 becomes a positioning shape portion 6 of the support frame described later.

On the other hand, reference numeral 7 denotes a support frame which has a U-shaped cross section opening inward, and whose dimensions, shape, etc. are selected so that the whole fits into the positioning shaped part 6, and is formed by bending a plate-like member.

Further, 8 is a film-like material, for example, a transparent heat ray reflective film made of a polyester film and a transparent heat ray reflective layer (for example, manufactured by Toray Industries, Inc. under the trade name "Lumisola" or manufactured by Sumitomo Three M, etc.).
Use the product name “Scotchitaint” etc.). The film-like body 8 is cut to be somewhat larger than the outer shape of the support frame 7. Then, it is applied to the side surface of the support frame 7 in a state where it is stretched uniformly in the vertical and horizontal directions to eliminate wrinkles, etc., that is, while maintaining its flatness, and further, more than half of the outer surface of the support frame 7 is pasted. The support frame 7 and the spacer member 4 are adhered to cover each other to strengthen the adhesion, and metal contact between the support frame 7 and the spacer member 4 is avoided to prevent abnormal noises that may occur during use. Note that silicone, epoxy, etc. can be used as the adhesive used for pasting.

Then, the support frame 7 to which the film-like body 8 is attached is fitted into the positioning shape portion 6 of the spacer member 4, and the film-like body 8 is placed approximately in the center between each glass plate 2, 3 as shown in FIG. A double-layer glass 1 is obtained.

Further, since the support frame 7 is formed in a U-shape, the interior thereof is filled with a sound absorbing material 9 such as glass wool or elastic foam (vinyl chloride foam, etc.) as shown in FIG.

As described above, in the first embodiment, the film-like body 8 is adhered to the support frame 7 in advance while maintaining a uniform plane,
By simply fitting the frame 7 into the spacer member 4, positioning is performed at the same time, and it can be easily assembled, has an excellent appearance, and has a sound insulation effect.

Next, a second embodiment of the present invention will be described with reference to FIG. This figure shows a cross-sectional view of the main parts of double-glazed glass.

The double glazed unit, indicated by the reference numeral 20 in the figure, is constructed by assembling glass plates 23 and 24 to a main body 21 with a sealant 22, and the glass plates are spaced apart by a predetermined width and face each other in parallel planes as in FIG. 1. A spacer member 25 is interposed between each of the glass plates 23 and 24, and this spacer member 25 is an integrally molded product made of a synthetic resin material, and a positioning portion 26 protruding from its upper surface with a rectangular cross section is also integrally molded. It has been done. This shaped portion 26 is formed biased to one side, and one side is located at the center of the spacer member 25.

On the other hand, 27 is a support frame which has the same function as the support frame 7 but has a different shape. In other words, it is formed into a U-shaped cross section, but opens outward. and,
The shape, dimensions, etc. of this opening portion are selected so that it fits into the positioning shape portion 26.

Reference numeral 28 denotes a film-like body which is first attached to the side of the support frame 27 as in the first embodiment, and then the second
As shown in the figure, it is pasted along the inner wall surface of the opening of the support frame 27 for a predetermined length.

Then, when the support frame 27 to which the film-like body 28 is attached is fitted into the positioning shape part 26 of the spacer member 25 (or the positioning shape part 26 is fitted into the support frame 27), as shown in FIG. A double-glazed glass 20 like this is obtained.

As described above, the present invention can be similarly applied to double-layered glass (included in double-layered glass in general concept). In addition, the second
In the embodiment, parts such as materials whose explanations are omitted can be implemented in the same manner as in the first embodiment, and the same effects as in the first embodiment can be obtained.

In addition, in the embodiments, arbitrary changes in the shapes of the space members, support frames, positioning shapes, etc., detailed configurations, etc., without departing from the gist of the present invention are permitted within the scope of the present invention.

As described above, the double-layer glass according to the present invention is obtained by preparing a support frame that fits into a space member interposed between a pair of glass plates, and pasting a uniformly stretched film-like body to this support frame. By assembling the film, it is easy to eliminate wrinkles, etc. from the film-like body, and it is possible to improve the appearance and, by extension, the marketability.

Moreover, at the same time, it is easy to assemble, and it is possible to improve the assemblability, and by selecting the shape of the support frame, etc., it is possible to add a sound absorbing material without impairing the appearance, and it is possible to improve the sound insulation effect.
