DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

A window hole 3 is formed in the door body 2, and the above-mentioned mounting frame 4 is omitted from the periphery of the window hole 3.

A frame bead 12 is mounted on the periphery of the window hole 3. The frame bead 12 is made of a synthetic resin, for example, soft vinyl chloride, and is a rod-shaped material. The frame bead 12 has a length corresponding to the peripheral length of the window hole 3, and is bent along the window hole 3. I will put it on. After the frame bead 12 is mounted, the window glass 6 is fitted, the holding bead 13 is fitted to the frame bead 12, and the window glass 6 is clamped between the frame bead 12 and the holding bead 13. The holding bead 13 is the frame bead 1
2 and a rod-shaped material made of synthetic resin.
Has a length corresponding to the frame bead 12 and is fitted while being bent along the holding bead 13.

The frame bead 12 will be described with reference to FIG.

FIG. 2 shows a cross-sectional shape of the frame bead 12, in which a glass plate holding ridge 14 is formed upward at the center, and a sealing tongue piece 15 is provided at an upper end of the glass plate holding ridge 14.
Is hanging. Horizontally extending shoulders 16 are formed at the base end of the glass plate holding projections 14, and fitting grooves 17 are formed on both sides of the shoulders 16. Downward hooks 18 and 19 are formed on both inner side walls of the fitting groove 17, and the fitting groove 1 is formed.
Further, a mounting groove 21 into which the front panel 20 of the door body 2 is inserted is formed outside the door 7. The glass plate holding projections 14
Is hollow at the bottom.

The holding bead 13 will be described with reference to FIG.

FIG. 3 shows a sectional shape of the holding bead 13.
A fitting portion 22 that can be fitted into the fitting groove 17 is formed in a lower portion, and the downward hook ridge 1 is formed on both outer surfaces of the fitting portion 22.
Upward hook grooves 23, 24 that mesh with 8, 19 are formed. The fitting portion 22 has a hollow shape so as to increase the amount of deformation in the thickness direction. At the upper part of the holding bead 13, a seal part 25 which also serves to hold the window glass 6 is formed. The seal portion 25 is inclined, and a seal tongue piece 26 is formed at an upper end of the seal portion 25, and a lower end of the seal portion 25 projects outward of the fitting portion 22.

Next, a procedure for assembling the window glass 6 will be described.

While the front panel 20 is inserted into the mounting groove 21 of the frame bead 12, the frame bead 12 is
Attach to the periphery of. The window glass 6 is fitted from both sides of the glass plate holding projection 14. The holding bead 13 is fitted over the entire length of the frame bead 12 while the fitting portion 22 is fitted into the fitting groove 17 in a state where the inner side surface of the window glass 6 is in contact with the sealing tongue piece 26. To wear.

When the fitting portion 22 is fitted into the fitting groove 17, the downward hook ridges 18, 19 and the upward hook groove 2 are formed.
The engagement of the fitting grooves 17 of the fitting portion 22 is reliably maintained. The upper end of the seal portion 25 contacts the outer surface of the window glass 6, and the lower end of the seal portion 25 contacts the inner peripheral surface of the holding bead 13.
Accordingly, by fitting the fitting portion 22 into the fitting groove 17, a sufficient pressure contact force of the sealing tongue piece 26 at the upper end of the sealing portion 25 to the window glass 6 can be obtained.

The window glass 6 is sandwiched between the glass plate holding ridges 14 and the sealing portion 25, and the window glass 6
Are sealed by the sealing tongue pieces 15 and 26. Further, as described above, since the seal portion 25 is integral and has no slope, and is further inclined, the seal portion 25 is excellent in aesthetic appearance and hardly accumulates dust.

When the window glass 6 is broken, the holding bead 13 is pulled out, the broken glass is removed, and the above-mentioned glass loading operation is performed, and the replacement operation is easy.

In the above embodiment, the structure for holding the window glass of the double glass window has been described. However, in FIG. 2, one fitting groove 17 is omitted, and the glass plate holding projection 1 on the omitted side is omitted.
Needless to say, if the sealing tongue piece 15 at the upper end of the window 4 is omitted, it can be implemented as a structure for holding a window glass of a single glass window.

Further, although the above embodiment has been described with reference to a round window, it is needless to say that the present invention can be applied to a square window.

[0023]

According to the present invention, as described above, the following excellent effects are exhibited.

Since the mounting frame on the door body side can be omitted and the number of parts is greatly reduced, the manufacturing cost is reduced.

The assembling operation is completed by attaching the frame bead to the door body and fitting the holding bead to the frame bead. The number of working steps is extremely small, and there is no troublesome work such as screwing and sealing work. The performance is greatly improved.

The appearance is improved because no screws are used,
In addition, since it is a synthetic resin molding, the shape can be freely selected, for example, the corner portion is formed into an R shape or the inclined surface of the seal portion is formed as a curved surface, so that the design value can be increased.

Since the seal portion has no discontinuous portion and is inclined, dust hardly accumulates and cleaning is easy.
