(N) In addition to the one-way transmission mechanism, the sliding piece and the elevating member are connected via a direction changing mechanism that changes the moving direction into a right angle, and the notch and the engaging groove match each other. As a result, the elevating member is displaced to the unlocked position.

(Operation) The operation of the emergency entry window of the present invention configured as described above is as follows.

During normal operation (when there is no fire), when opening a closed window shoji for ventilation or cleaning, open and close the window shoji by operating the lock handle provided on the indoor side of the window shoji. Do.

This opening and closing work is the same as in the case of an ordinary window. That is, at this time, the movement of the elevating member is not transmitted to the other member, that is, the horizontal frame or the sliding piece provided on the horizontal frame, by the action of the one-way transmission mechanism. The opening with does not match. For this reason, the window shovel remains in a state where the opening is limited by the connecting arm.

Also, in the event of a fire, when opening a closed window shoji from the outdoors, the drive mechanism provided on the outdoor side of the window is operated, and the sliding piece is moved along the other member to create a notch. And the openings of the engaging groove and the engaging groove are matched.

As a result, when the window screen is rotated from the closing direction to the opening direction, the engagement shaft provided at the end of the connecting arm can be detached from the other member to the rear side in the rotation direction of the window screen. .

At the same time, the movement of the sliding piece is transmitted to the elevating member via the direction changing mechanism and the one-way transmission mechanism, and like the case of operating the locking handle, the window sliding door is unlocked and the window sliding door can be opened. It will be in a state.

When the window screen is rotated in the opening direction from this state, the engagement groove at the end of the connecting arm is disengaged from the other member, and the window screen is opened greatly without the opening of the connecting arm being restricted. Can be done.

(Embodiment) Next, the present invention will be described in more detail by explaining the embodiment shown in FIGS.

As shown in FIG. 10, the emergency entry window of the present invention includes a window frame 1 composed of upper and lower horizontal frames 5 and 5 and left and right vertical frames 3 and 3.
The window screen 2 is fixed inside the window opening and the window screen 2 is built inside the window frame 1. The window shoji 2 is composed of upper and lower horizontal frames 6 and 6 and left and right vertical frames 4 and 4 that surrounds the glass 7 around four sides. Then, one vertical frame (left side in FIG. 10) that constitutes the window shoji 2 and one vertical frame 3 that constitutes the window frame 1 are provided with a pivot mechanism as shown in FIG. The windows can be opened and closed freely by connecting with each other.

The pivoting mechanism is one in which the tip end of the supporting arm 8 whose base end is pivotally supported by the horizontal frame 5 by the vertical axis is pivotally supported by the other vertical axis on the upper and lower ends of the vertical frame 4 of the window shoji 2. . When opening the window shoji 2, the window shoji 2 has the vertical frame 4 separated from the vertical frame 3,
It is pushed out to the outdoor side (upper side in Figs. 1 and 5).

The horizontal groove 5 (one member) forming the lower side of the window frame 1 having the window shovel 2 built therein as described above is provided with a loose groove member 9 as shown in FIG. It is fixed in all directions.

The loose groove member 9 formed by bending a metal plate is
Along the lengthwise direction (left-right direction in FIG. 3), the play groove 10

The engaging shaft 16 has a size that allows it to enter, and when the engaging shaft 16 enters the notch 18, the tip of the connecting arm 15 is pivotally supported on the intermediate portion of the horizontal frame 6. I am doing it.

A sliding piece 19 is provided between the upper surface of the bracket 17 and the lower surface of the horizontal frame 6 so that the sliding piece 19 can be freely moved in the longitudinal direction of the horizontal frame 6. The sliding piece 19 is formed with a horizontally long L-shaped engagement groove 20. The engagement shaft 16 can be freely inserted into the engagement groove 20, and the engagement groove 20 opens to the indoor side similarly to the cutout 18. The engaging groove 16 supported at the tip of the connecting arm 15 can be pulled out indoors from the bracket 17 fixed to the horizontal frame 6 when the openings of the notch 18 and the engaging groove 20 are aligned. . On the other hand, as shown in FIG. 2, when the opening of the notch 18 and the opening of the engaging groove 20 do not coincide with each other, the engaging shaft 16 has the notch 18
It remains trapped in the back of the. In this way, when the engagement shaft 16 is confined in the depth of the notch 18, the tip of the connecting arm 15 is pivotally supported by the bracket 17 fixed to the lower surface of the horizontal frame 6, and the window shovel 2 The opening degree of is limited by the connecting arm 15.

On the other hand, among the vertical frames 4 and 4 constituting the window shoji 2, the outer peripheral side surface of the vertical frame 4 on the side not pivotally supported by the window frame 1 is provided on the indoor side of the vertical frame 4, for example, FIG. An elevating member 22 that can be moved up and down by a locking handle 21 as shown in FIG. Then, the lifting member 22 and the sliding piece 19 are
One-way transmission mechanism 23, direction conversion mechanism 24, transmission rod 25
It is connected via a and 25b.

The one-way transmission mechanism 23 in this does not transmit the movement of the lifting member 22 by the locking handle 21 to the sliding piece 19,
It is for transmitting the movement of 9 to the elevating member 22, and is configured as shown in FIGS.

That is, the clutch plate 28 is provided on the outer peripheral side surface of the vertical frame 4 at a position overlapping the lower end of the elevating member 22. The clutch plate 28 includes guide pins 26, 26 and the guide hole 2.
By engaging with 7, 27, it is only possible to move up and down. The upper end of the transmission rod 25a is connected to the clutch plate 28. The pin 29 protruding from the inner peripheral side surface of the intermediate portion of the clutch plate 28 is loosely fitted in a long hole 30 formed in the lower end of the elevating member 22 and extending in the vertical direction.
This pin 29 moves to the lower end of the long hole 30 when the window shovel 2 is in the locked state based on the operation of the locking handle 21, and the window shovel 2 is also moved based on the operation of the locking handle 21. In the unlocked state, this long hole 30
The position at which the pin 29 and the long hole 30 are provided and the length thereof are determined so that the pin 29 and the long hole 30 can be moved to the upper end of the.

Therefore, based on the operation of the locking handle 21, the lifting member 2
When the roller 34 and the abutment piece 35, which will be described later, are engaged and disengaged, the pin 29 only moves between the upper end portion and the lower end portion of the elongated hole 30, and this movement is transmitted. Two
It is not transmitted to 5a.

On the other hand, when the transmission rod 25a is pulled downward from the state in which the pin 29 is located at the lower end of the elongated hole 30 in the locked state based on the operation of the locking handle 21, the pin 29 is moved to the above-mentioned state. It moves downward while being in contact with the lower end of the long hole 30. Therefore, the lifting member 22
Is pulled downward, the roller 34 moves below the abutment piece 35, and the locked state of the window shoji is released regardless of the locking handle 21.

In addition, the transmission rod 25a whose upper end is connected to the clutch plate 28 and moves in the vertical direction, and the transmission rod 25b whose one end is connected to the sliding piece 19 and moves in the horizontal direction are mutually moved by the direction changing mechanism 24. Are connected. The direction changing mechanism 24 changes the moving direction into a right angle. For example, as shown in FIG. 7, in a hollow casing 31 bent at a right angle in an intermediate portion,
It is configured by inserting a transmission material having rigidity and flexibility such as a spring material. Therefore, the transmission rod 25b moves horizontally as the transmission rod 25a moves up and down.

Further, as shown in FIG. 1, a side arm 32 having its base end fixed to the middle portion of the transmission rod 25b is provided to the outside of the outside through a horizontally long through hole (not shown) formed in the outside surface of the side frame 6. And a drive mechanism for opening the window shovel 2 from the outdoor side in an emergency in the front end together with the side arm 32.
The handle 33 is fixed.

In the emergency entry window of the present invention configured as described above,
At normal times (when there is no fire), when opening the window shutter 2 in the closed state for ventilation or cleaning, the window shutter 2
By operating the lock handle 21 provided on the indoor side, the window shovel 2 is opened and closed.

This opening / closing work is the same as in the case of a normal window, and after the window shovel 2 is moved to the inside of the window frame 1, the locking handle 21
Rotate to the locked state. By rotating the locking handle 21 to the locked state, as shown in FIGS. 7 to 8, the roller 34 provided on the elevating member 22 is attached to the abutment piece 35 fixed to the inner peripheral side surface of the vertical frame 3, Engage to ride up. As a result of this engagement, the window screen 2 is prevented from moving in the opening direction, and at the same time, the inner side surface of each of the frames 4 and 6 is fixed to the window frame 1.
It is pressed against the packing attached to the window so that the inside and outside of the window screen 2 is kept airtight.

When opening the window shoji 2, the lock handle 21 is rotated in the opposite direction to lower the elevating member 22 slightly from the state shown in FIGS. 7 to 8, and the roller 34 and the abutment piece 35 are separated. Is disengaged so that the window screen 2 can be opened.

In this way, when the normal opening and closing work is performed, the pin 29 is only displaced between the upper and lower ends of the elongated hole 30. Therefore, the movement of the elevating member 22 causes the one-way transmission mechanism 23 to move.
Is not transmitted to the sliding piece 19 provided on the horizontal frame 6.

In other words, even when the elevating member 22 moves up and down based on the operation of the locking handle 21, the one-way transmission mechanism 2
The pin 29, which is fixed to the clutch plate 28 that constitutes No. 3, only moves up and down inside the elongated hole 30 provided at the lower end of the elevating member 22. As a result, the movement of the lifting member 22 is not transmitted to the clutch plate 28.

Therefore, the sliding piece 19 connected to the clutch plate 28 (via the transmission rod 25a, the direction changing mechanism 24, and the transmission rod 25b) does not move, and the opening of the engagement groove 20 formed in the sliding piece 19 is formed. The opening of the notch 18 formed in the bracket 17 does not match. Therefore, the window shoji 2 is connected to the connecting arm 1.
The opening degree remains limited by 5.

Further, when the window shovel 2 in the closed state is to be opened from the outdoors in the event of a fire, the handle 33, which is provided on the outdoor side of the window shovel 2, and constitutes a drive mechanism is moved as shown by an arrow X in FIG. Let Along with this movement, the sliding piece 19 moves along the horizontal frame 6 that constitutes the window shoji 2, and is fixed to the opening of the engaging groove 20 formed in the sliding piece 19 and the lower surface of the horizontal frame 6. The opening of the notch 18 formed in the bracket 17 of the above corresponds to the opening of the notch 18.

As a result, the engagement shaft 16 provided at the tip of the connecting arm 15 is
It can be freely dropped from the horizontal frame 6 to the indoor side of the window shoji 2.

At the same time, the horizontal movement of the sliding piece 19 is transmitted to the elevating member 22 via the transmission rod 25b, the direction conversion mechanism 24, the transmission rod 25a, and the one-way transmission mechanism 23.

That is, when the transmission rod 25a descends as the sliding piece 19 moves, the pin 29 fixed to the clutch plate 28 connected to the upper end of the transmission rod 25a and the long hole formed at the lower end of the elevating member 22. By the abutment with the lower edge of 30, the lifting member 22
Goes down. Therefore, similarly to the case where the locking handle 21 is operated, the roller 34 provided on the elevating member 22 is disengaged downward from the abutting piece 35 fixed to the vertical frame 4. As a result, the window screen 2 is unlocked, and the window screen 2 can be opened.

When the window screen 2 is rotated from this state in the opening direction, the engagement groove 16 provided at the tip of the connecting arm 15 comes out from the notch 18 of the bracket 17 fixed to the horizontal frame 6, and the window screen 2
Can be largely opened without the opening being restricted by the connecting arm 15.

The clutch plate 28 of the one-way transmission mechanism 23 and the lifting member 2
The pin 29 and the long hole 30 fixed to or formed on
The pins 29 are provided on the members opposite to each other in the illustrated example, and are locked when locked.
Can also be configured to exist at the upper end of the slot 30. Further, since the locking mechanism is configured, the vertical frame 3 and the lifting member 22
The roller 34 and the abutting piece 35 provided in the and can also be provided in members opposite to the illustrated example.

Furthermore, even if the parts where each member is provided are reversed between the frame and the frame,
It can be configured similarly.

(Effect of the device) Since the emergency entrance window of the present invention is configured and operates as described above, even when a glass panel with wire mesh is used, it enters indoors without using a special device. It becomes possible to do. As a result, when used as an entrance for fire fighting, there is no need to waste significant time for digestion activities.
It is possible to carry out effective fire fighting and rescue activities.
