Consisting of an adhesive tape having
The width of the protective tape covering the outer edge of the glass plate is 1 to 10 m
m.

[0007] For example, Japanese Patent Application Laid-Open No. 4-55349 discloses that the outermost portions of two outermost glass plates are coated with a metal thin film in a multi-layered glass, and the outermost portions are formed along the outer peripheral portions of the glass plates. A double glazing in which a flexible metal strip is brazed together to both metal films is described.

Further, for example, Japanese Utility Model Application No. 59-113106.
No. (No. 61-30040), a plurality of glass plates are opposed at regular intervals by spacers arranged between the ends, and each glass plate is sealed by a sealing material filled between the glass plates outside the spacers. A double-layer glass in which a glass plate is hermetically bonded, an end of the glass plate is housed in a bead having a substantially U-shaped cross section, and the bead and the glass plate are bonded to a body by a sealing material, The bead is a synthetic resin molded product in which flanges made of a hard material are formed at the upper ends on both sides of a U-shaped main body made of a soft material by body molding, respectively.
The connection is performed by adhesion or fusion, and the main body is inserted into the sash, and each flange is attached to the sash by engaging the flange with the flange of the sash opening edge, so that the whole can be handled as a body. It is disclosed that attachment to a sash can be performed with a simple construction that simply requires fitting the end portion into the sash.

Further, for example, Japanese Patent Application Laid-Open No. 7-71170 discloses a channel-shaped reinforcing material capable of surrounding the periphery of a double-glazed glass, and an internal soft material provided on the inner side surface of the reinforcing material facing the double-glazed glass. And a multi-layer glass with an attachment in which an attachment made of an external soft material provided on the outer surface engaging with the sash is attached to the peripheral edge portion, and the external soft material is related to a tip edge of a mounting opening of the sash. The stopper is provided, and the reinforcing material can be metal or synthetic resin, etc., usually aluminum, steel, stainless steel, etc., most preferably aluminum, and further as an internal soft material and an external soft material.

The upper part including the wing-shaped arm is made of a soft synthetic resin material, and the part excluding the upper part is made of a semi-rigid or hard synthetic resin material. Have been described.

Further, for example, Japanese Patent Application Laid-Open No. Hei 2-26118
No. 6 describes a method for manufacturing a glass window with a frame in which a synthetic resin frame is molded around the periphery of a double glazing by pressing a softened synthetic resin immediately after extrusion molding.

As a method for directly extruding a frame in a double-glazed glass with a resin frame, for example, Japanese Patent Application Laid-Open No. 6-321
585, JP-A-7-17748, JP-A-7-17
No. 291678 is known.

[0014]

For example, the edge protector for double glazing described in Japanese Utility Model Publication No. Sho 63-747 has an excellent effect on places where pressure such as water pressure is applied, particularly on aquarium tanks. Even if it brings
Normal window glass has excessive performance and is difficult to adopt from the viewpoint of cost and the like.

Further, for example, in the case of a double-glazed frame described in Japanese Utility Model Publication No. 60-28780, it is difficult to obtain flexibility in a U-shaped cross section, a precise size and shape of the frame are required, and workability is not always required. It is difficult to say that it can be performed simply and efficiently.

Further, for example, a sealing material for double-glazing described in JP-A-60-250084,
No. 9908 (Japanese Utility Model Application Laid-Open No. 3-101793), the tape that can be adhered to the double-glazed glass described in the microfilm, especially for large-area and heavy-weight double-glazed glass, prevents breakage during transportation and handling. Or sealing performance,
And it is hard to say that it is sufficient for the performance of preventing slippage between the glass plates.

For example, in the case of a flexible metal band or a metal thin film in a double glazing described in JP-A-4-55349, for example, the metal band and the metal thin film cannot be said to be inexpensive in terms of material cost. It is difficult to say that it is necessarily preferable as a sealing member for double-glazing because it needs to be brazed.

Further, for example, Japanese Utility Model Application No. 59-113106.
No. (No. 61-30040), a bead having a substantially U-shaped cross section in the double glazing described in the microfilm,
For example, even if it is a synthetic resin molded product in which a flange made of a hard material is formed at the upper end on both sides of a U-shaped main body made of a soft material by a body molding, especially in a large area or heavy weight double glazing, The soft material is easily damaged by the two glass plates and easily develops the deformation and deterioration due to the load, and is not necessarily sufficiently durable. However, it cannot be said that the sealing can be performed smoothly with good sealing properties, and the strength of the joint between the soft material and the hard material is not always sufficient.

Further, for example, in the attachment in the double-glazed glass with an attachment described in Japanese Patent Application Laid-Open No. 7-71170, a soft material is provided on the inner and outer surfaces of the reinforcing material. There is a surface that cannot be said to be a mechanical seal, and the external soft material is not sufficiently strong in strength due to the action of a shearing force, and it is necessary to increase the contact area.

Further, for example, in the attachment for double glazing described in Japanese Patent Application Laid-Open No. 7-259443, the cushioning member is formed of a synthetic resin material such as semi-rigid or rigid polyvinyl chloride, and the bead member has a wing-shaped arm portion. The upper part including is made of a soft synthetic resin material, and the part excluding the upper part is made of a semi-rigid or hard synthetic resin material. The incorporation force at the interface with is not always sufficient.

Further, for example, Japanese Patent Application Laid-Open No. Hei 2-26118
No. 6 discloses that the synthetic resin frame being softened immediately after heating or immediately after extrusion molding is press-bonded to form the synthetic resin frame around the periphery of the double-glazed glass. Even if the adhesiveness to the double-glazed glass is good and the sealing property is simply improved, it is difficult to achieve both the protection of the edge portion of the double-glazed glass and the efficiency of the assembling work, and at the same time to sufficiently improve it.

Further, for example, Japanese Patent Application Laid-Open No. Hei 6-3215
No. 85, JP-A-7-17748, JP-A-7-291678, and the like, a direct-body extrusion molding method of a frame in a double-glazed glass with a resin frame is performed by protecting an edge portion of the double-glazed glass and incorporating the same. Although there is a possibility that both efficiency can be improved and sufficient improvement can be achieved at the same time, it is not always possible to say that sufficient improvement and sufficient economy are required.

In any of the above, after the Grechan was attached to the peripheral edge of the double-glazed glass sheet, there was a risk of deformation such as lifting near the center of the linear portion. Further, for example, in the bead material in the double-layer glass structure described in Japanese Utility Model Application Laid-Open No. 7-15989, a bead material is fixed and arranged in advance on the exposed peripheral edge of the glass plate. A hard bead portion provided with a fitting protrusion to be fitted and covered on the peripheral surface of the double-glazed glass, and a portion of the hard bead portion which covers the exposed peripheral portion of each glass plate. It is formed with a soft bead part to be provided, and a hard bead part is fitted or only a soft bead part with a hollow part on the-side is not necessarily sufficiently simplified. It is hard to say that the Grechan structure. Further, when trying to press-fit the fitting protrusion of the bead material into the fitting groove provided in the spacer described in this publication, the adhesive between the peripheral portion of the glass plate and the side of the spacer is not completely solidified. If the bead material is to be mounted at this stage, the position of the spacer is shifted from a predetermined position, so that there is a problem that the bead material cannot be mounted until the adhesive is solidified.

[0024]

[0030]

BEST MODE FOR CARRYING OUT THE INVENTION In a Grechan used to surround a peripheral surface and an end surface of a glass plate, a laminated glass, or a double-glazed glass, a cross section of the Grechan is approximately 1 mm from the inner bottom surface of the substantially U-shaped main body. The above-mentioned square or cylindrical projection is vertically provided, and a constricted (constricted) portion, a concave portion, a through hole, or the like is provided on the intermediate portion or the bottom surface side for retaining the projection, or the tip is anchored. (Ikari) -shaped retaining part was provided.

In surrounding the above-mentioned Grechan around the outer periphery of the double-glazed glass, a spacer is adhered to the peripheral edge of the double-glazed glass, and a secondary sealing material is filled between the outer peripheral side of the spacer and the glass plate. Before the next sealing material is solidified, the Grechan is surrounded by the outer peripheral portion of the double-glazed glass, and a protrusion provided on the inner bottom of the cross-section substantially U-shaped main body of the Grechan is embedded in the secondary sealing material, and the sealing is performed. When the material is solidified, the solidified secondary sealing material exists around the constricted portion of the projection, so that the fitted Grechan does not come off and float.

With respect to a hard or semi-hard U-shaped cross-section main body surrounding the peripheral surface and the end surface of the glass plate, laminated glass or double-glazed glass, the peripheral surface and the end surface of the glass are subjected to an external pressure such as an impact. Hard or semi-hard material and U-shaped cross-section that have a function and strength that at least have hardness to withstand and protect against water and moisture such as water and external force and moisture, and elasticity to sandwich the peripheral surface and end surface of the glass. It consists of the thickness, dimensions and shape of the main body.

Next, regarding the semi-rigid or soft substantially U-shaped seal section provided at both ends on the opening side of the U-shaped main body section, not only the sealing performance with the glass outer surface but also the sash A semi-rigid or soft material having a function and strength that at least has sealing properties and locking properties at the opening edge flange of the sash when attaching various types of glass, and the thickness, dimensions and shape of a substantially U-shaped cross-section sealing portion Consists of

Further, the hard or semi-rigid U-shaped cross-section main body and the semi-rigid or soft cross-section substantially U-shaped seal portion individually and synergistically exhibit their functions. -In order to exert the strength and to have the strength, the substantially U-shaped seal portion is softer than the substantially U-shaped main body portion, and the substantially U-shaped main body portion and the substantially U-shaped seal portion are used. The part facing is formed with at least two types of materials by means of solidification molding, for example, co-extrusion molding, and furthermore, at the solidification part, a convex shape is formed on the surface of the substantially U-shaped sealing section. A concave portion is provided on the surface of the main body portion having a substantially U-shaped cross section, and the convex portion is fitted in a sandwiching manner so as to be wrapped by the concave portion to form a body.

In particular, in the integrated portion, the convex portion on the surface of the substantially U-shaped cross-section sealing portion is fitted and sandwiched so as to be wrapped by the concave portion on the surface of the substantially U-shaped cross section main body. By doing so, the bending or tensile strength in the body-forming part and the repetition strength thereof are provided, and the stress is dispersed not in a simple plane-body but in an inclined volume-body in the body-forming part. In this manner, the seal portion having a substantially U-shaped section can be protected by the distal end of the substantially U-shaped cross-section of the body portion as much as possible.

Further, the soft U-shaped seal portion having a substantially U-shaped cross section has a tongue-like portion for sealing and a flange portion at both U-shaped tip regions corresponding to the inner surface, and a U-shaped central back region corresponding to the outer surface. The tongue-shaped portion and the flange portion to appropriately develop a fitting force to the glass, thereby providing a sealing property. At the same time as having a holding property at the same time, when attaching a double-glazed glass with Grechan to a sash, at the same time as providing a sealing property by aligning with the sash opening edge flange by the protruding piece-shaped portion and the groove-shaped portion, The tongue-like portion and the flange further exert a pressing force against the glass surface due to the action force of providing the locking property and the aligning and locking with the sash opening edge flange, so that the sealing is performed. It can be assumed to have also to balance potentially be allowed to increase sexual and retention as appropriate.

Also, the tongue-shaped portion is disposed above the integrated portion of the substantially U-shaped seal portion in cross section, so that the tongue-shaped portion and the flange portion are formed in a suction cup shape. The reason for this is that, by forming and acting on the sash, the sealing and holding properties are further exhibited, and when the sash is attached to the sash, the protrusion and the groove make the sash more effective.

Further, by providing a hard or semi-rigid or soft protruding portion on the inner side surface of the hard or semi-rigid substantially U-shaped cross-section main body, the sealing property against glass surface and the impact resistance are improved. In some cases, it is preferable to appropriately arrange them in a rib shape on the side surface side and a rail shape on the end surface side.

Further, by arranging a through hole at the center bottom of the main body having a substantially U-shaped cross section, it can also serve for draining, for example. Further, since the above-mentioned Grechan is provided around the entire periphery or a part of the double-glazing so as to surround the peripheral surface and the end surface of the double-glazing, the mounting operation of the Grechan is extremely simple and at the site. In addition to eliminating complicated operations, the glass is double-glazed with Grechan, especially its movement, transportation, storage, installation work on the sash, etc. is extremely simple and efficient, and the glass is protected and damaged. The present invention is safer and has a remarkable effect in the double glazing having a larger weight and a larger area.

It goes without saying that tempered glass, glass with increased strength, bent glass, glass with various functional films, colored glass and the like can be used as the double-glazed glass. Further, it goes without saying that the glass may be inorganic, organic or a combination thereof.

According to the glazing for double glazing of the present invention and the mounting structure thereof, at least the cross section has a substantially U-shaped main body section and a substantially U-shaped cross section sealing section made of a specific material. The main body portion having a substantially U-shaped section and a substantially U-shaped section.
In the body-shaped seal part, the convex part in the body part is fitted in a sandwich shape so as to be wrapped by the concave part to form a body, so that the body part is slanted and volumetric. As a result, Grechan itself is made to have extremely excellent bending and tensile strength.

Furthermore, long-term durability is provided, and when attached to the glass, particularly a double-layer glass, the work can be performed simply and efficiently, and the holding power thereof can be made sufficient.

Further, a retaining portion is provided on a protruding portion which is suspended from an inner bottom surface of the main body of the Grechan in a substantially U-shaped cross section, and the surrounding of the Grechan to the outer peripheral portion of the multilayer glass is defined by the outer periphery of the multilayer glass. Before solidification of the secondary seal material to be filled in, the protrusion of Grechan is embedded in the secondary seal material so that the secondary seal material is solidified, and the secondary seal material around the retaining portion of the protrusion portion Is solidified, so that the fitted Grechan does not come off and float.

Furthermore, protection of damage resistance and the like and protection of water resistance and the like at the peripheral surface side and the end face of the glass, which are the respective roles of the substantially U-shaped cross-section main body and the substantially U-shaped cross-section seal, are extremely important. Therefore, even if the double-glazed glass with Grechan increases in weight and area, it can be easily moved, transported, or stored. In addition, handling is extremely excellent, such that the work of attaching to the sash can be smoothly and smoothly fitted with the main body portion having a substantially U-shaped cross section. In addition, the increased strength and durability, as well as the high watertightness and the high mounting force, are useful for maintaining the quality of the double glazing, especially for a long term.
