BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, a door 5 is attached to a door frame 4 in which an upper frame 1, a lower frame 2 and left and right vertical frames 3 are formed into a rectangular frame. This door 5 connects the upper and lower frames 6 and 7 to the left and right vertical frames 8
The frame body 9 is abutted and connected to the frame body 9 and the panel body 10 is mounted in the frame body 9. One vertical frame 3 and one vertical frame 8 are connected by a hinge 11, and a handle 12 is attached to the other vertical frame 8.

The upper frame 6, the lower frame 7, and the vertical frame 8 are shown in FIGS.
As shown in FIG.
The attachments 14 are fitted and attached to each other and fixed with screws, and the attachments form a mounting frame. The attachment 14 has an L-shape with a lateral piece 15 facing out-of-plane and an inward piece 16 serving as a door stop. The horizontal piece 15
And a pair of projecting pieces 17 are integrally provided on the inwardly facing piece 16, and an airtight material mounting portion 18 is provided on the inward piece 16.
An airtight material 19 is attached to 8.

As shown in FIGS. 2 and 3, the panel body 10 has a panel 24 mounted in a frame body 23 in which an upper horizontal member 20, a lower horizontal member 21, and left and right vertical members 22 are formed into a rectangular frame. . One of the vertical members 22 (the handle 1
Pins 26 are attached to the upper and lower parts of the outer surface of the vertical member 22) facing the vertical frame 8 to which the 2 is attached via brackets 25, and the pin 26 at the upper portion is a horizontal piece 15 of the attachment 14 attached to the upper frame 6. Is rotatably supported in the out-of-plane direction and is movable in the in-plane direction, and the lower pin 26 is rotatably supported in the in-plane direction by the lateral piece 15 of the attachment 14 attached to the lower frame 7. I am doing it.

As shown in FIG. 2, a guide block 27 is attached to the lower surface of the lower horizontal member 21 near one of the vertical frames 8, and the guide block 27 is attached to the horizontal piece 15 of the attachment 14 attached to the lower frame 7. The panel body 10 is positioned in the vertical direction by contacting with it, and is supported so as to move smoothly in the in-plane direction and the out-of-plane direction. The lower pin 26 is in contact with the bottom surface 13a of the inward recess 13 of the lower frame 7 to support the panel body 10.

Next, details of the support portion of the pin 26 will be described. As shown in FIGS. 4 and 5, the upper and lower portions of the vertical members 22 are cut and removed leaving the outer vertical plates 22a, and the upper horizontal members 20,
The ends of the lower horizontal member 21 are abutted against the remaining outer vertical plate 22a and are connected by screws 28 screwed into the screw holes 20a and 21a. The screw 28 also serves to attach the bracket 25.

An elongated hole 30 is formed in the lateral piece 15 of the upper and lower attachments 14 attached to the upper and lower frames 6 and 7 in the in-plane direction, and a pin 26 slides in the elongated hole 30. It is inserted freely. The longitudinal frame 22 side of the elongated hole 30 is inclined toward one side in the out-of-plane direction. One end of an arm 32 is rotatably supported in the out-of-plane direction by a screw 31 screwed to the upper horizontal piece 20b of the upper horizontal member 20 and the lower horizontal piece 21b of the lower horizontal member 21, respectively. Screws 33 inserted into the ends are screwed into the lateral pieces 15 of the attachment 14 and are rotatably supported in the out-of-plane direction.

Therefore, when the panel body 10 is rotated in the out-of-plane direction in the direction of the arrow a, the arm 32 swings in the out-of-plane direction around the screw 33 and the screw 31 screwed into the panel body 10 is removed. Since it moves along the circular arc locus b, the pin 26
While sliding in the in-plane direction along the long hole 30, the panel body 1
0 rotates in the direction of arrow a.

The vertical member 22 and the vertical frame 8 on the side opposite to the pin 26.
A thumb-turn type lock 40 for locking the panel body 10 is attached to the lock body 40. The lock 40 can be locked and unlocked by a knob 41 on the indoor side.

Next, the operation of opening the panel body 10 will be described. As shown in FIG. 6, when the panel body 10 is closed, the pins 26 are located at the slanting portions of the elongated holes 30.
Moves toward the inward piece 16 of the attachment 14 and presses against the airtight material 19, so that the watertightness between the panel body 10 and the attachment 14 is improved.

When the knob 41 of the lock 40 is unlocked by rotating and the panel body 10 is rotated in the direction of arrow a, the arm 32 swings and the pin 26 slides along the slot 30 as described above. While the panel body 10 is rotating, the pin 26 becomes a linear portion of the slot 30 as shown in FIG.

As a result, the panel body 10 moves in a direction away from the inward piece 16 of the attachment 14 in the out-of-plane direction, and the panel body 10 is separated from the airtight member 19, so that one vertical member 22 of the panel body 10 is attached. It smoothly rotates without interfering with the inwardly facing piece 16 of 14 and the airtight material 19.

When the panel body 10 is further rotated in the direction of arrow a from the above-mentioned state, the pin 26 is rotated while sliding along the elongated hole 30 and the panel body 10 is moved in the in-plane direction as shown in FIG. Move and open 90 degrees. In this way, the panel body 1
0 opens by rotating while moving in the in-plane direction, that is, it opens in a sliding manner.

Therefore, when the panel body 10 is opened 90 degrees, it does not interfere with the handle 12. For example, as shown in FIGS. 1 and 8, when the handle 12 projects toward the panel body 12 and the pin 26 is located on the opposite side of the handle body 12, the handle 12 and the panel body 10 interfere with each other and cannot be opened. . Further, if the panel body 10 is supported by a pin that does not move in the in-plane direction, when the panel body 10 is opened approximately 45 degrees, the panel body 10 interferes with the handle 12 and the opening angle is small, making it difficult for people to enter and leave.

The attachment 1 is attached to each frame of the frame assembly 9.
4, the panel body 10 is mounted in the attachment 14, and the panel body 10 is pressed against the inward piece 16 (door stop) of the attachment 14 via the airtight material 19. Each frame can be the same as each frame of the normal door frame assembly, and the appearance as a door is the same as a normal door.

Further, since the attachment 14 is a separate body for each of the upper and lower sides and the left and right sides, the elongated hole 30 can be easily processed.

[0025]

According to the first aspect of the invention, the inside of the frame assembly can be released by opening the panel assembly. As a result, by making the door a hinged door attached to the door frame, the panel body is opened from the inside of the frame assembly in an emergency when the door frame is deformed due to an earthquake or the like and interferes with the door and the door cannot be opened. It is a hinged door that allows people to come and go.

Further, since the fulcrum of rotation of the panel body is close to one of the vertical frames to which the handle is attached, the panel body can be opened without interfering with the handle even when the handle projects toward the panel body.

According to the second aspect of the invention, since the panel body is rotated and opened while moving toward the other vertical frame, the opening angle of the panel body can be increased even when the handle is projected toward the panel body. . This allows a person to smoothly enter and leave the inside of the frame assembly in an emergency.

According to the third aspect of the present invention, the frame assembly can be made to be similar to a normal door frame assembly, and the appearance of the door can be made to be similar to a normal door, and the panel body can be attached to the door stop of each attachment. It can be in contact with and closed.
