When such a bead is fitted and mounted on the peripheral portion of the glass panel, in order to secure the water and airtightness by connecting the seal portion in the circumferential direction of the glass panel, for example, as shown in FIG. Preferably, the ends of the beads 3 are cut at an angle of about 45 degrees so that the ends of the beads 3 are joined at the corners, and the cut end faces 25 are preferably bonded together with an adhesive or the like.

[0003]

However, as described above, in the beaded glass panel in which the bead is mounted around the glass panel or in the door in which the beaded glass panel is mounted, the cut end faces 25 of the bead are connected to each other. Since the beads are tightly joined with an adhesive, etc., the thermal expansion and contraction of the beads cannot be tolerated or absorbed.If the beads contract due to thermal contraction or aging, stress concentrates on the joints of the beads, As shown in FIG. 7 (b), the joint between the cut end faces 25 is peeled off to generate a gap s, which causes a problem that water and airtightness are reduced and appearance is deteriorated.

It is an object of the present invention to provide a beat-equipped panel and door which can allow thermal expansion and contraction of the bead while ensuring water and airtightness, and have a good appearance.

[0005]

In order to achieve the above object, a beaded panel according to the present invention has a corner piece having a substantially groove-shaped cross section at each corner of the panel and extending along the corner. And a bead having a substantially groove-shaped cross section is fitted and mounted on each side between the corner pieces of the panel, and a panel and a frame to which the panel is mounted are provided on upper edges of both sides of the corner piece and the bead. And a seal portion for sealing the space between the bead and the seal portion of the corner piece is extended by an appropriate length to cover the seal portion of the bead.

In the door according to the second aspect, a corner piece having a substantially groove-shaped cross-section along the corner is fitted and mounted in each corner of the panel, and a cross-section is generally formed in each side between the corner pieces of the panel. A groove-shaped bead is fitted and mounted, and a seal portion for sealing between a panel and a frame to which the panel is attached is formed on both upper edges of the corner piece and the bead. A beaded panel which is appropriately extended to cover the bead seal portion is formed, and the beaded panel is attached to a frame.
