Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a buffer and water / airtight bead mounted on a peripheral portion of a glass panel and a glass panel mounted with the bead.

[0002]

2. Description of the Related Art Generally, in a sash or the like, when a glass is attached to a frame or a frame of a shoji, a bead, which is also called a packing or a glazing channel, is attached to a peripheral portion of a glass panel for cushioning and water / airtightness. It This bead is disclosed in, for example, Japanese Utility Model Publication No. 52-145946.
Japanese Utility Model Publication No. 48-144956, Japanese Utility Model Publication No. 3-1281.
As described in Japanese Patent Laid-Open No. 88, etc., it is formed in a long shape with a substantially groove-shaped cross section, and is attached by being wound while being fitted around the peripheral edge of the glass panel. In this case, in order to secure water / airtightness, it is preferable that the ends of the beads are bonded to each other with an adhesive or the like.

FIG. 13 shows a glass panel 1 having a bead 2 mounted on the periphery thereof. In this glass panel 1, the ends of the beads are cut at an angle of approximately 45 degrees so that the ends of the beads 2 are joined at the corners, and the cut end faces 15 are shown in FIG. 13 (a). It is tightly joined with an adhesive or the like. It should be noted that the place where the ends of the bead 2 are joined is not limited to the corner, but may be a straight part, in which case the end of the bead is cut at a right angle to the longitudinal direction.

[0004]

However, in the above bead or glass panel, when the ends of the bead 2 are joined together with, for example, an adhesive, it is necessary to apply the adhesive along the cut end surface 15. There was a problem that joining work was time-consuming. In addition, since sufficient joining strength cannot be obtained by joining the cut end surfaces 15 to each other, there is a problem that the joining portion is easily peeled off due to impact or external force when a frame is assembled. If the bead shrinks due to heat shrinkage or aging due to peeling of the bonded portion, a gap s is generated between the cut end faces 15 as shown in FIG. It also doesn't look good.

Therefore, an object of the present invention is to provide a bead and a glass panel which can improve the workability when joining the ends of the bead and the joining strength.

[0006]

In order to achieve the above object, the invention according to claim 1 of the present invention provides a tongue piece portion at one end portion for joining the end portions of the bead. It is characterized in that the tongue piece is joined to the other end.

The invention according to claim 2 is characterized in that, in order to join the ends of the bead, the joining face material is joined across both ends.

In the invention according to claim 3, a bead is attached to the peripheral edge of the glass panel, and a tongue piece is provided at one end in order to join the ends of the bead to each other. It is characterized in that it is joined to the other end.

The invention according to claim 4 is characterized in that a bead is attached to the peripheral portion of the glass panel, and in order to join the ends of the bead, a joining face material is joined across both ends. And

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 is a glass panel mounted on a frame of a shoji such as a window sash or a terrace sash, and a bead 2 is mounted on the peripheral edge of the glass panel 1. The glass panel 1 is made of a multi-layer glass in which a pair of plate glasses 3 are laminated with a square frame-shaped spacer 4 interposed therebetween as shown in FIGS. 7 to 8. It is preferable that the spacer 4 is formed in a hollow shape and filled with a desiccant in order to prevent fogging due to moisture inside the double glazing.

The bead 2 has a cross section having a bottom portion 5 abutting against the end surface of the glass panel 1 and both side portions 7 rising from both sides of the bottom portion 5 and forming a groove 6 for accommodating the edge of the glass panel 1. It has a substantially bead-shaped hard bead body 8 which is continuous and long. A soft collar portion (also referred to as a flange portion) 9 is integrally provided on the upper edge portions of both side portions 7 of the bead body 8, and the collar portion 9 is formed on the inner peripheral surface of the frame 10 and the surface of the glass panel 1. It is constructed so as to straddle and seal between them. In addition, it is preferable that drain holes 11 are formed in the bottom portion 5 of the bead 2 located on the lower side of the glass panel 1 at appropriate intervals in the longitudinal direction.

Inside the both side parts 7, a soft extending part 12 is formed extending obliquely downward from the upper edge part thereof, and extends over the extending part 12 and the inner edge part of the collar part 9. The width adjusting plate portion 13 having a laminated structure is provided so as to be peelable. That is, the bead 2 can be adapted even if the thickness t of the glass panel 1 is large by appropriately peeling and removing the width adjusting plate portion 13. The bead body 8
Is formed of a rigid resin, preferably rigid vinyl chloride,
The collar portion 9, the extending portion 12 and the width adjusting plate 13 are made of a soft resin, preferably soft vinyl chloride.

The opening width wa between the collar portions 9 including the width adjusting plate 13 is preferably about the same as the thickness t of the glass panel 1 from the viewpoint of the mountability to the glass panel 1. On the other hand, the frame 10 is composed of, for example, an upper frame, a lower frame, and left and right vertical frames made of an extruded profile of aluminum alloy,
It is constructed so that it can be assembled in a rectangular shape with screws. On the inner circumference of the frame 10, the peripheral edge of the glass panel 1 is provided with beads 2.
A glass mounting groove 14 for fitting through is provided. Immediately below the flange portion 9 and outside the upper edges of both side portions 7 of the bead body 8, engagement grooves 15 that engage with the edges of the glass mounting groove 14 of the frame 10 are formed.

In both sides 7 of the bead body 8, the width wb on the bottom 5 side is smaller than the opening width wc of the glass mounting groove 14, and the width wd on the upper edge side is the opening width w of the glass mounting groove 14.
It is preferable that it is formed in a taper shape that widens toward the end so as to be larger than c from the viewpoint of the mountability to the frame 10.
Further, with the above-mentioned shape, the bead body 8 is attached to the glass mounting groove 1
When fitted in 4, the width between the upper edge portions of the both side portions 7 of the bead body 8 is narrowed, and the glass panel 1 can be sandwiched and securely fixed via the collar portion 9 and the extending portion 12.

As shown in FIG. 1, the beads 2 are divided beads 2A continuously attached to one side edge and an upper edge of the glass panel 1, and the other side edge and a lower side of the glass panel 1. It is divided into two parts, that is, a divided bead 2B which is continuously attached to the edge portion. It is difficult to continuously and stably extrude a long hard bead 2 to be used for a glass panel 1 having a long peripheral edge (about 6 to 8 m) like a shoji on a terrace sash by an extruder. Therefore, if the bead 2 is divided into two or more parts and manufactured as described above, a bead having a stable shape and quality can be easily obtained.

Since the divided beads 2A and 2B have symmetrical shapes, one of the divided beads 2A will be described in detail. As shown in FIG. 2, the split bead 2A has cut end faces 15 cut at a cutting angle α of about 45 degrees located at the corners of the glass panel 1 at both ends in the longitudinal direction, and a glass is cut at a substantially middle part. In order to form a corner portion located at a corner portion of the panel 1, a cutout portion 17 is provided so as to have a cutout end surface 16 at an opening angle β of about 90 degrees, leaving a bottom portion 5.

As a result, the divided bead 2 has two bead portions 2a and 2b which are continuously fitted and mounted on the adjacent side edge portion and upper edge portion or the side edge portion and lower edge portion of the glass panel 1.
A is obtained. The cutting angle α is set to an angle slightly smaller than 45 degrees, and the opening angle β is set to an angle slightly smaller than 90 degrees in order to improve the adhesion between the cut end surfaces 15 and the cutout end surfaces 16 that face each other. Is preferably provided.

At one end of the divided bead 2A,
A planar tongue piece portion 18 formed by extending a part of the bottom portion 5 which is a part of the tongue piece portion 18 is provided.
Is joined to the ends of the other split bead 2B that is abutted at the corners as shown in FIG. 3, so that the ends of the adjacent split beads 2A and 2B are joined together. In this case, the tongue piece portion 18 of one of the divided beads 2A or 2B is bent and joined so as to overlap with the outer surface of the bottom portion 5 which is the corresponding surface of the end of the other divided bead 2B or 2A by surface contact.

As a method for joining the tongue pieces 18, for example, adhesion with an adhesive is preferable, but welding with heat, chemicals or the like may be used. As the adhesive, for example, a vinyl chloride-based adhesive (including an instant adhesive) is preferable. in this case,
An adhesive may be applied to the adhesive surface (inner surface) of the tongue piece portion 18 and attached to the outer surface of the bottom portion 5 of the other split bead.

When the tongue pieces 18 are joined by thermal welding, for example, a welding machine 26 having a plurality of protrusions 25 as shown in FIG. 5 is used and the welding is performed as shown in FIG.
In this case, in order not to damage the spacers 4 and the like of the glass panel 1, the insertion depth of the protrusion 25 is larger than the thickness of the bottom portion 5 of the bead body 8 plus the thickness of the tongue portion 18. It is preferable to make it small. The welding work can be easily performed with the bead 2 mounted on the glass panel 1, so that the productivity is good.

When an adhesive is used as the joining means of the tongue piece 18, the tongue piece 18 is easily peeled off until the adhesive is solidified. Therefore, as a temporary fixing to prevent this, as shown in FIG.
It is preferable that the adhesive tape 20 be attached so as to cover the entire joint portion 19 including the tongue portion 18 as shown in FIG. In this case, as the adhesive tape 20, a tape having a width that can cover the outer surface of the bead body 8 is used, and the notches 21 are formed on both sides thereof so that the entire bonding portion 19 can be attached from the outside. preferable. As a result, it is possible to prevent the initial peeling of the tongue piece portion 18 due to the adhesion, and
It is possible to further improve the watertightness and airtightness between the cut end faces 15 that are in close contact with each other.

In order to obtain the glass panel 1 constructed as described above, first, the two divided beads 2A and 2B formed as shown in FIG. 2 are fitted to the peripheral portion of the glass panel 1 as shown in FIG. Mounting. Next, in a state where the cut end surfaces 15 of the divided beads 2A and 2B adjacent to each other at the corner portion are in close contact with each other, the tongue piece portion 18 formed at one end of one divided bead 2A or 2B is connected to the other divided bead 2B. Alternatively, it may be joined to the outer surface of the bottom portion 5 at the end of 2A with, for example, an adhesive.

As a result, the glass panel 1 having the bead 2 endlessly attached to the peripheral portion thereof can be obtained. After joining the tongue pieces 18, in some cases, an adhesive tape 20 may be attached so as to cover the joining portion 19 as shown in FIG.
Alternatively, the cut end surfaces 15 of the divided beads 2A and 2B or the cut end surfaces 16 may be joined with an adhesive.

The bead 2 is mounted in a factory, for example, but since the bead main body 8 is hard and has a substantially groove-shaped cross-section that widens toward the end, it can be performed quickly and efficiently unlike a soft bead that easily bends. . The glass panel 1 is
Since the bead 2 having the hard bead body 8 is preliminarily attached over the entire length of the peripheral portion, the peripheral portion is protected, so that the bead 2 is safe and easy to carry, store and handle.

When a shoji such as a sash is assembled using the glass panel 1, the glass panel 1 is inserted through the beads 2.
The upper frame, the lower frame, and the left and right vertical frames may be assembled to the four sides by fitting the glass mounting grooves 14 to each other, and then the frame 10 may be assembled. Such an assembling work is performed in, for example, a builder, but the beads 2 are attached to the glass panel 1 in advance, and both side portions 7 of the bead body 8 are formed in a taper shape which is wide at the end and hard and smooth. Since it can be fitted into the glass mounting groove 14 of the frame 10, the assembling work can be performed quickly and easily, and the workability can be improved.

As described above, according to the bead 2 and the glass panel 1, in order to join the ends of the bead 2 mounted on the peripheral edge of the glass panel 1, the tongue piece 18 is provided at one end. Since the tongue piece portion 18 is provided and joined to the other end portion, the end portions of the bead 2 can be joined very easily and reliably with a simple structure.
It is possible to improve workability and joint strength. That is, when the ends of the bead 2 are joined to each other, only the tongue piece portion 18 provided at one end needs to be joined to the other end by, for example, an adhesive, so that the entire cut end face 15 is covered. Unlike the conventional adhesive coating method, the joining work can be easily performed, and the workability, work efficiency and productivity can be improved.

Further, since the tongue piece portion 18 can secure a joining area which is sufficiently larger than the joining of the cut end surfaces 15, the joining tongue portion 18 can obtain sufficient joining strength. Therefore, even when an impact, an external force, or the like is applied to the joint portion 19 of the bead 2 when the frame 10 is assembled, the joint portion 19 is not likely to separate. Further, even when the bead 2 shrinks due to heat shrinkage or aging, it is possible to prevent the formation of the gap between the cut end faces 15, so that the water / airtightness does not deteriorate and the appearance does not deteriorate.

Further, by covering the entire joint portion 19 including the tongue piece portion 18 with the adhesive tape 20, it is possible to prevent the tongue piece portion 18 from peeling off due to the adhesion, and to cut the pieces to face each other. Water / airtightness between the end faces 15 can be further improved. Moreover, since the bead 2 is divided into a plurality of pieces, stable extrusion molding can be performed, and the bead 2 can be easily applied to a glass panel having a long peripheral edge.
