BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the framed door 1 of the present invention will be described in more detail based on examples. FIG. 1 is a front view showing an embodiment of the framed door 1 of the present invention, showing a state viewed from the outside of the room. In addition, FIG. 2 shows AA of FIG.
FIG. 3 is a sectional view taken along line BB in FIG.

The framed door 1 according to the present embodiment is a hinged door type door installed at a front door, and a substantially frame-shaped door frame 10 is fixed to a concrete frame forming a wall. 1
A substantially rectangular plate-shaped door body 2 is hung at one side end of 0 through hinges 3 and 3. The door frame 10 includes two vertical frames 13,
14 are vertically arranged apart from each other, and the upper and lower horizontal frames 11, 12 are arranged so as to bridge the upper and lower ends thereof.
Is installed horizontally.

The door body 2 of the present embodiment is a metallic flush door, and one end side thereof has at least two upper and lower portions.
The individual hinges 3 and 3 are attached, and the hinges 3 and 3 are hung and installed on the vertical frame (the vertical frame on the hanging side) via the hinges 3 and 3.
Due to the hinge 3, the door body 2 becomes a hinged door that can be opened and closed in the front-rear direction.

Two locks, a first lock 4 and a second lock 30, are attached to the door body 2. The first box lock 4 is built in the center of the door body 2 at the end on the door tip side in the vertical direction. The box lock 4 includes a box body 20, and the box body 20
The latch 21 and the dead bolt 6 are configured to be able to project from the door end side end surface of the. The box lock 4 is attached to the door body 2 and then the lever 2 installed on the front and back surfaces of the door body 2.
The forward / backward movement of the latch 21 can be operated by using a knob 2 or a knob.

The latch 21 has a substantially triangular cross section,
It is constantly urged so as to project from the end surface of the box body 20 on the door end side, and the latch 21 is provided with the box body 2 against the urging force.
It can be pushed back to the 0 side. Also, this latch 2
1 can be stored on the side of the box body 20 by pushing down the lever 22.

The levers 22 are installed on the front surface and the back surface of the door body 2, and are normally stationary in a horizontal state. Usually, the latch 21 projects toward the door end side by the urging force. When attempting to close the door body 2, the door end side vertical frame 13
The latch 21 comes into contact with, but since the contact surface is inclined, the door body 2 is closed while the latch 21 is pushed into the box body 20.

When the door body 2 is completely closed, the latch 21 projects from the door tip 2a by the urging force and projects into the recess 13a formed on the side surface of the door tip side vertical frame 13.
As a result, the door body 2 is in a state in which it cannot be freely opened and closed.

When the door main body 2 is opened, if the lever 22 is rotated in the lowering direction, the door tip 2 is interlocked with this operation.
Since the latch 21 protruding from a is stored in the box body 20, the door body 2 can be opened.

On the other hand, the dead bolt 6 has a rod shape having a substantially rectangular cross section, and can be moved forward and backward from the end face of the box body 20 on the door end side. The dead bolt 6 can be moved by the key operation of the cylinder lock 5 installed in the box body 20.

When the key is turned to lock the door body 2 with the door body 2 closed, the dead bolt 6 projects from the door tip 2a, and inside the first recess 13b formed on the side surface of the door tip side vertical frame 13. The tip part rushes into. Therefore, even if the lever 22 is rotated to open the door, the dead bolt 6 cannot be opened because the dead bolt 6 contacts the inside of the first recess 13b. If the user wants to unlock the key, he or she may insert the key into the cylinder lock 5 and rotate the key in the opposite direction. As a result, the dead bolt 6 is housed inside the box body 20, and the door body 2 can be opened by operating the lever 22.

The second box lock 30 is also attached to the door body 2 like the first box lock 4. In this embodiment, as shown in FIG. 1, the second box lock 30 is built in slightly on the door tip side of the center of the door body 2 in the left-right direction and slightly above the center of the door in the up-down direction (may be on the lower side). To be done. This box lock 30 is a box 3
2, the box 32 is provided with rods 33 and 34 that can move forward and backward in the vertical direction.

The rods 33 and 34 are in the shape of a vertically elongated round bar, and can be moved by the key operation of the cylinder lock 31.
Further, the rods 33 and 34 are passed through a pipe 35 arranged inside the door body 2, and are configured to be able to project from the upper and lower end surfaces of the door body 2.

When the key is turned to lock the door body 2 in the closed state, the two rods 33 and 34 are locked by using a cam mechanism, a link mechanism, a gear or the like built in the box 32. It can move vertically outside. Along with this, the tip end portions of the rods 33 and 34 project from the upper and lower end surfaces of the door body 2, and the tip end portions thereof are projected into the respective second recessed portions 11a and 12a formed in the upper and lower horizontal frames 11 and 12.

As a result, even if the lever 22 is rotated to open the door, the two rods 33 and 34 are not moved to the second position.
It cannot be opened by coming into contact with the inside of the recesses 11a and 12a. If the user wants to unlock the key, he or she may insert the key into the cylinder lock 31 and rotate the key in the opposite direction. As a result, the rods 33 and 34 are housed inside the door body 2, and the door body 2 can be opened by operating the lever 22.

As shown in FIG. 3, the second recesses 11a and 12a are shaped such that their widths have seismic resistance gaps X and X on the left and right sides of the rods 33 and 34, respectively. The size of the gap X is set appropriately, but in the present embodiment, for example, X = about 14 mm. This is to enable the door to be opened and closed without difficulty even when the door body 2 or the door frame 10 is deformed due to an earthquake or the like. By providing the gap X only in the surface direction, it is possible to provide earthquake resistance without affecting the door locking effect.

By the way, in the above embodiment, it is described that the door is locked / unlocked by the key operation from the outside of the room. However, from the indoor side, the thumb turn is rotated to lock / unlock the door. Of course, it is also good.

As described above, the framed door 1 of the present invention
Is a difficult structure for thieves to enter. In other words, the door body 2 is fixed to the door frame 10 on all four sides with the hinge 3, the dead bolt 6, and the rods 33 and 34. As a result, even if the door tip 2a alone is pry open with a bar or the like, the door does not open, and it takes time to pry open the upper and lower parts of the door, and the thief gives up.

Further, since the upper and lower rods 33 and 34 can be locked by one cylinder, the key operation can be performed at two places, even though the one door 3 is locked. Further, the seismic resistance required for the entrance door is increased by making the second recesses 11a, 12a in which the respective tip portions of the upper and lower rods 33, 34 are arranged, so that even if the door is deformed, And the second
Earthquake resistance is ensured by preventing the recesses 11a and 12a from interfering with each other.

The crime prevention door with a frame according to the present invention is not limited to the structure of the above-mentioned embodiment, but can be modified appropriately. For example, in the case of a cylinder lock having a structure that is not picked, one key hole may be used to lock in three directions.
