Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double glazing to be mounted on a window opening of a vehicle or a building, and more particularly to a double glazing with beads which can be easily and quickly mounted on a sash.

[0002]

2. Description of the Related Art In order to enable simple and quick assembly on a sash constituting a frame such as a window opening, a double-glazing unit in which a fitting member made of a synthetic resin is previously attached to the periphery of a glass plate. There is used a multi-layer glass with a bead in which a bead of a synthetic resin member is directly formed integrally with a glass plate constituting the multi-layer glass.

FIG. 16 is an external view of such a multi-layer glass with beads. Beads 2 made of a resin member are continuously and integrally mounted on the peripheral edges of both surfaces of the multi-layer glass 1. Such a bead 2 can be continuously mounted as one bead along the four sides of the glass plate while being extruded using a resin material extruder (for example, JP-A-9-207188). ). In this case, the bead on both sides can be directly bonded onto the glass surface while simultaneously forming the beads on both sides along the peripheral edge of both surfaces of the double-glazed glass to which the adhesive has been applied in advance. A bead mounting operation can be performed.

When the bead 2 is integrally formed with the double-glazed glass 1 by using such an extruder, one corner of a glass plate constituting the double-glazed glass 1 is set as a starting point 2a along four sides as indicated by arrows. The bead 2 is formed continuously, and the end point 2b is joined to the start point 2a by returning to the first corner. Thereby, the joint 1 between the start point 2a and the end point 2b of the bead 2
3 is formed.

[0005]

However, if the seam 13 is formed at the corner as in the bead 2 of FIG. 16 described above, it takes much time and effort to complete the finishing process, and even if the finishing is performed with much effort, The appearance did not improve so much and the merchantability was impaired.

When the bead 2 is continuously formed on the periphery of the double-glazed glass, as shown in FIG. 15, the bead swells outward at a right-angled corner 2c, causing poor bonding between the bead and the glass plate. In some cases, a shape defect occurred.

[0007] In addition, a soft bead such as a vinyl chloride resin is used for such a bead so that the bead can be easily assembled to the sash and the fitting property with the sash is improved. For this reason, although the glass edge around the entire periphery of the multilayer glass is covered with beads, the glass edge is not sufficiently protected because the material is a soft resin. In other words, if the glass edge hits a concrete floor or wall during transportation or assembly, the glass edge may be chipped, and the corners may be inadvertently hit and damaged.

Further, as shown in FIG. 13, the sash shoji 6 to be assembled to the double-glazed glass 5 with beads is usually assembled in a cross-girder shape. In this case, as shown in FIG. 14 showing a cross section in the EE direction of FIG. 13, the distance d2 between the sash engaging portions 2d of the front and back beads 2 is the groove width d of the sash shoji 6.
Greater than 1. At the corner 2c in FIG. 15, the sash engaging portion 2d of the bead 2 is bent in an arc shape to form a vertical wall. Therefore, when assembling the sash to the corner 2c from the vertical and horizontal directions, the frame (stile) tip 6a of the sash shoji 6 in FIG. 14 is in a state of crushing the vertical wall of the sash engaging portion 2d of the bead 2 from the vertical and horizontal directions. And the bead is deformed, and the corner is not settled properly.

The present invention has been made in consideration of the above-mentioned prior art, and eliminates the trouble of finishing a seam at a corner, improves the appearance, enhances design and commerciality, and enhances protection of a glass corner portion. An object of the present invention is to provide a double-glazed glass with a bead that prevents damage to the glass and improves the fit of a corner when a sash is mounted.

[0010]

In order to achieve the above object, according to the present invention, there is provided a multi-layer glass with a bead in which a glass edge at a peripheral portion including all corners of a glass plate constituting the multi-layer glass is covered with a resin member. In the above, the resin member is composed of two or more different members, the first member is a resin member provided at least at one corner of the glass plate,
The second member is a resin member provided on a peripheral portion of a glass plate including a side portion of the glass plate and not provided with the first member.

According to this structure, since the bead at the corner portion is formed as the first member different from the second member at the side portion, the appearance of the corner portion can be improved to enhance the design and the commerciality. Further, since a separate component having high hardness can be easily formed, the protection strength of the corner can be increased.

In a preferred configuration example, the second resin member is
A continuous body formed by continuously covering four sides and the remaining three corners of the glass plate with one corner as a starting point, and joining the starting point and the ending point with the corner of the starting point as an ending point. The first member is a resin member that joins a start point and an end point of the second member. According to this configuration, since the first member is attached to the corner of the joint between the start point and the end point of the second member that is continuously formed along the periphery of the glass, the work for finishing the joint is omitted and the appearance is reduced. Is improved, and the design and commercial properties are enhanced.

[0013] In a further preferred configuration example, the first member is provided at all corners of the double glazing.

According to this configuration, all four corners are protected by the first member having high strength.

In a further preferred configuration, the first member is made of a material having a higher hardness than the second member.

According to this configuration, the hardness of the first member provided at the corner portion is larger than that of the second member provided at each side of the glass periphery, thereby protecting the glass edge at the corner portion.

In a further preferred configuration, the height of the upper surface of the first member from the glass surface is lower than the height of the sash engagement portion of the second member.

According to this configuration, since the upper surface of the first member at the corner portion is lower than the sash engaging portion of the second member, the upper surface of the first member is deformed by being hooked on the frame end of the sash when the sash is assembled. The sash can be mounted smoothly from the vertical and horizontal directions at the corner, and the fit of the corner can be improved.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a corner portion of the double-glazed glass with beads according to the embodiment of the present invention. FIGS. 2, 3 and 4 are a side view and a top view, respectively, as seen from directions B, A and D in FIG. FIG. 5 is a cross-sectional view taken along the line CC of FIG.

As shown in these figures, corner parts 3 are attached to the corners of the double-glazed glass 1. As shown in FIG. 5, the double-glazed glass 1 is obtained by bonding two glass plates 1a and 1b together with a sealing material 7 bonded through a spacer 8 therebetween. The corner component 3 is joined to the glass surface via an adhesive 4. The corner part 3 is composed of a pedestal portion 3a that covers the glass edge 1f of the multilayer glass 1 and a sash fitting portion 3b whose height from the glass surface (height in a direction perpendicular to the glass surface) is increased. Is done.

The pedestal portion 3a is formed of a hard type, for example, a hard vinyl chloride resin having an HRC hardness of 100 degrees or more, and the sash fitting portion 3b is formed of a soft type, for example, a soft vinyl chloride resin having an HsA hardness of 60 degrees. . In this case, the soft sash fitting portion 3b can be integrally formed with the pedestal portion 3a by a molding method of foaming in the hard pedestal portion 3a. The hardness and the material are not limited to the above examples.

Also, the shape is not limited to the above example, and the soft resin member of the sash fitting portion may be formed by forming the hard member and the soft member as separate members instead of the configuration in which the soft resin member is foamed inside the hard member. Alternatively, the whole may be formed of a hard member, and the inside of the sash fitting portion 3b may be hollowed out to be softened as shown in a bead 2 in FIGS. Good.

As described above, the glass edge portion is covered with the hard pedestal portion 3a and the sash fitting portion is formed of a soft material, thereby protecting the glass edge at the corner portion without hindering the sash assembling operation. Can be strengthened.

This corner part 3 is formed, for example, by the aforementioned FIG.
The start point and the end point of the continuous bead 2 shown in FIG. FIG.
FIG. 7 is a perspective view of the state before the corner component 3 is mounted on such a corner, and FIGS. 7 and 8 are side views as seen from the direction B and the direction A in FIG. 6, respectively.

At the time of integrally forming the bead 2 on the multi-layer glass,
From the state where the start end and the end end intersect, FIGS.
As shown in FIG. 8, each of the start end and end end is cut at right angles to the longitudinal direction of the bead to remove the bead at the corner. The above-mentioned corner part 3 shown in FIG. 5 is joined with the adhesive 4 on the glass surface of the corner from which the bead has been removed. As shown in FIG. 9, the connection surfaces between the corner component 3 and the bead 2 can be joined and integrated with each other by an adhesive 4 as needed to improve airtightness and watertightness.

As described above, such corner parts 3 may be provided only at one corner where the start point and the end point of the continuous bead 2 are joined, or may be provided at all four corners. By providing them at all four corners, the glass edges of the corners are all covered with hard corner parts, thereby preventing damage such as chipping of the glass. Also, as in the case where beads are continuously formed and bent at right angles at corners,
It is possible to reliably cover all corners with the resin member without causing the beads at the corners to bulge outward and cause poor joint and poor shape.

The upper surface 3c of the corner part 3 is shown in FIG.
As shown in FIG. 2, the height of the sash engagement portion 2d of the bead 2 from the glass surface is lower than the height of the sash engagement portion 2d.
(See FIG. 14), the sash can be smoothly fitted without being deformed.

FIG. 10 is a sectional view of a corner portion according to another embodiment of the present invention. In this embodiment, the double glazing 1
The base 3a of hard resin covering the glass edge 1f of each of the glass plates 1a and 1b is formed by integrating resin members on both sides so as to wrap the ends of the double-glazed glass 1 from both sides. With such a configuration in which the corner parts on both sides of the double-glazed glass are integrated, the work of attaching the corner part 3 to the double-glazed glass corner is facilitated, the workability is improved, and the glass edge portion is sufficiently protected.

[0029] Such a corner part made of a composite molded product of different materials can be mass-produced at low cost by using an injection molding machine and a mold. The connection position between the corner part 3 and the bead 2 may be slightly outside the intersection Z inside the orthogonal bead 2 as shown in FIG. 11, or may be a position coincident with the intersection Z. Good. S in FIG. 11 indicates a connection line between the corner part 3 and the bead 2.

FIG. 12 shows still another embodiment of the present invention. In this embodiment, a corner component 30 that covers only the corner glass edge is attached as a separate component with a hard resin material only for the purpose of protecting the glass edge. Such corner components 30 protect the glass edge.

[0031]

As described above, in the present invention, at least one corner of the double glazing with beads is provided.
Since the corner parts are assembled as separate members,
The corners can be reliably covered with a resin member.For example, by attaching corner parts to the joints of beads that are integrally molded into a double-glazed glass, the finishing process of the joints is simplified and the appearance is improved. The appearance is improved, and the design and commercial properties are improved. In addition, since a separate component having high hardness can be easily formed, forming the corner component with a hard material can increase the protection strength of the corner of the double-glazed glass. Further, if the sash fitting portion of the corner part is formed of a soft member, the fitting property with the sash is not impaired.

In addition, by forming the upper surface of the corner component lower than the height of the sash engagement portion of the bead, the upper portion of the corner component is not deformed by the sash frame tips from the vertical and horizontal directions when the sash is assembled. The sash can be fitted smoothly, and the corner parts can be easily accommodated.
