Each frame main body 20 has a glass fitting groove n continuously formed in the longitudinal direction and having the same expected width as the thickness of the peripheral end of a glass plate n, which will be described later. The protruding piece 2] is provided to protrude in a direction opposite to the opening side of the knobblast fitting groove B, and a lip groove is formed on the outdoor side surface of the protruding piece 21 by locking pieces 24, 24 whose tips are bent in the direction of each other. 5 are formed continuously in the longitudinal direction. Each frame material 17, 18.

A welding material 26 such as butyl rubber or silicon is embedded in the inner bottom of the glass fitting groove n of 19, and the frame is assembled in a rectangular shape so that each glass plate fitting groove n is on the inner circumferential side and each protrusion 21 is on the indoor side. Then, the peripheral edge of the glass plate n is located in the glass plate fitting groove part n.
A glass frame body C is constructed by being fitted therein.

The upper frame material 17 and the left and right vertical frame materials 18 , 18 , or the lower frame material 19 and the left and right vertical frame materials 18 , 18 are temporarily fixed until the adhesive 26 exerts adhesive strength, and then the frame materials 17 , 18 , 19 are fixed together.
They are connected by corner connectors to prevent them from shifting. As each corner connector, a member made of synthetic resin as shown in Figures 1-4 can be used. That is, the cross section is the same as that of the lip grooves 5 of the frame members 17, 18, and 19, and the lip grooves 5 are tightly press-fitted, and the corner airtight cushioning material is continuous to the width center of the interior side surface. It is an L-shaped member with a protrusion formed thereon. Only the lip groove 5 of the vertical frame member 18 is extended vertically, and the locking pieces 24 on the side members 17 and 19 are slightly notched from the ends. Upper and lower horizontal frame members 17, 1
The end portions of the corner connectors γ are aligned with the lip grooves 5 of the vertical frame member 18, and each end of the corner connector γ is fitted into the continuous vertical and horizontal lip grooves 5, 25 for connection. Corner connector 27

An airtight cushioning material 29 is fitted in the lip groove 5 of 19 other than the portion where the corner connector 27 is fitted. As the airtight cushioning material 29, materials such as synthetic rubber and mohair can be used.

At the tip of the protruding piece 21 of the upper frame member 17, a locking piece U is slightly extended to form an abutting piece 30 that protrudes to the outside of the room. Contact piece (
9) The tip is slightly higher than the tip of the airtight cushioning material 29, and protrudes so as to be flush with the rear of the protrusion of the corner connector 27.

Projection piece 2 of lower frame material 19] Bearing part 31 with a C-shaped cross section at the tip
is formed, the bearing part 31 is placed on the shaft part 16 of the lower stile 8, and the glass frame C can be tilted inwards around the pivot part made up of the shaft part 16 and the bearing part 31.

The upper end of the glass frame C is fixed by a fixing means. As the fixing means, bolts 32 are used as shown in Fig. 1, and the member is fixed to the upper stile 6 of the shoji A with the bolt 32 passing horizontally through the upper frame 17 of the glass frame C from the indoor side. Alternatively, the glass frame C is fixed by screwing into a female screw portion provided on the upper stile.

When the glass frame C is attached to the shoji A as described above, the airtight cushioning material 29 attached to the protrusions 21 of the upper and lower frame members 17 and 19 of the glass frame C is inside the upper and lower frames 6 and 80 of the shoji A. The airtight cushioning material 29 of the left and right frame members 18, 18 abuts against the protrusions 11, 11 of the left and right vertical frames 7, 7. At the corner portion of the glass frame C where the airtight cushioning material 29 is not attached, the protrusion of the corner connector r comes into contact with the stile 6.8 or the protrusion 11 to maintain airtightness. Also, the upper frame material 17
When the contact piece I at the tip of the projection piece 21 comes into contact with the upper frame 6 and is fixed with the bolt 32, the airtight cushioning material 29 is not crushed more than necessary. The airtight cushioning material 29 protrudes toward the outside of the room from a protruding piece that protrudes toward the indoor side of the expected width, and the airtightness cushioning material 29 is thicker than the expected width of the glass frame C (does not protrude, and is attached to the frames 6, 7, etc.). The glass frame C can be neatly accommodated within the expected width of 8.

In addition, the airtight cushioning material 29 attached to the protruding piece of the lower frame material 19 is close to the shaft support, so that when the glass frame C is closed, the airtightness cushioning material 29 comes into accurate contact, improving airtightness. , deformation of the pivot parts 16 and 31 of the glass frame C is also less likely to occur.

Although this invention has the above-described configuration, as shown in FIG.
The locking pieces 24 on the side of the horizontal frame members 17 and 19 are slightly rounded at the ends, and a portion slightly away from the tip is cut out, and the other locking piece 24 is cut out a predetermined length slightly from the end. This vertical frame material 18
The T-shaped corner connectors may be fitted into the lip grooves 5 of the upper and lower frame members 17 and 19 through the notches of the locking pieces 24.

In addition, as shown in Figure 6 and Figure 7, the frame material 17°18,
The protrusions 34, 34 are projected from the left and right side walls in directions facing each other into the glass fitting groove section 19, and the adhesive 26 is pushed up to the protrusions 34, 34, between the glass plate fitting groove Tasoko wall and the protrusions 34 p 34. The end portion of the corner connector, which is an L-shaped metal fitting, may be inserted into the connector.

A pressure contact portion 35, 35 is formed in the corner connecting portion n by bending a portion slightly away from the tip and protruding from one side.

Therefore, according to this embodiment, the mounting groove 5 of the airtight cushioning material 29
Since the glass fitting groove and the glass fitting groove are formed separately, the airtight buffer ring can be fitted continuously without cutting at the corner, and the corner connector r can also be made into a simple shape.

In addition, the shaft portion 16 is not limited to the above embodiments, and the shaft portion 16 is connected to the glass frame C1.
The bearing portion 31 may be provided on the stile or frame side to constitute a pivot portion.

Furthermore, the present invention can be widely applied to doors, windows, etc.

〔Effect of the invention〕

The present invention has the above configuration and can obtain the following effects.

■ The glass frame has a rectangular frame material that has a glass fitting groove with the same expected width as the thickness of the peripheral edge of the glass plate, and the glass plate is fitted into it, so the expected width of the glass frame is the minimum. The expected width of frames and window frames can also be reduced.

O Since the upper and lower frame members and the vertical frame members are connected using corner connectors, it is possible to prevent the frame members from shifting and to temporarily secure them until the adhesive material exerts its adhesive strength.

If the conventional method of installing the glass frame is done in a sliding manner, it is necessary to form a groove with a width slightly larger than the expected width of the glass frame before installation, which increases the expected width of the frame or frame. Width is also required, but if the pivot point between the glass frame and the sash can be made to fold inward as in the present invention, the storage area of the glass frame can be minimized, and the expected width of the stile or frame can also be reduced. can.

■ An airtight buffer is attached to the protrusion of the glass frame, so
The airtight cushioning material contacts the stile or frame to maintain airtightness and prevent rattling of the glass frame.
