It is defined that the window frame 2, the second window frame 3, and the lock lever 4 are in the unlocked state. In this figure, the second window frame 3 is in a slightly opened state. However, regardless of whether the window frames 2 and 3 are actually opened, if the lock lever 4 is at the position shown in FIG. Since the window frames 2 and 3 can be opened, it is defined that the lock is released even if the window frames 2 and 3 are not open.

As described above, the window lock automatic opening device according to the present invention includes an inner frame portion indicated by reference numeral W1 in FIG.
In the space formed between the outer frame portion indicated by reference sign W2,
The apparatus is characterized in that the window lock automatic opening device (hereinafter, sometimes simply referred to as an opening device) is provided. The size of the space is indicated by oblique lines. The opening device may be arranged in any part of this space, but it is preferable to use the space near the lock lever 4.
By arranging the opening device in such a space portion, the opening device does not protrude inside the window glass or outside the window frame, and the view as the window is not spoiled. Further, since the opening device is not exposed to the outside, there is no hindrance when the rescue squad enters the room.

Next, the characteristic structure of the window lock automatic opening device used for the window frame unit according to the present invention will be described. First, a transmission member connected to a lock member for manually switching the window frame between a locked state and an unlocked state, and a transmission member for transmitting a driving force to the transmission member, The transmission member is configured to be movable from a first position not engaged with the transmitted member to a second position engaged with the transmitted member, and the first window is moved in the step of moving the second position. It is characterized in that the frame is automatically switched from the locked state to the unlocked state. According to this configuration, when the transmitting member is at the first position, the transmitting member is not engaged with the transmitted member connected to the locking member. Therefore, in this state, the locking member is in the free state, and the locking member is manually moved. The window frame can be manually switched between a locked state and an unlocked state. Then, when the transmission member is moved from the first position to the second position using an appropriate driving means such as a motor, the transmission member and the transmitted member are engaged, thereby moving the lock member and locking the window frame. It automatically switches from the state to the unlocked state. As described above, the window lock automatic opening device can be realized by a simple combination of the transmitting member and the transmitted member.
When the window lock is automatically opened, the rescue squad can open the window from the outside so that rescue operations can be performed.

Further, the second window frame is slid with respect to the first window frame to open the window, and the second window frame does not slide with respect to the first window frame. A window release mechanism capable of switching between an operation state and an operation state is further provided, and in a step after the transmission member has moved to the second position, the window release mechanism can be switched from the non-operation state to the operation state. preferable. According to this configuration, the window frame is automatically switched from the locked state to the unlocked state by the movement of the transmission member, and the window is actually opened. As a result, the rescue squad from outside can immediately identify the room where the person to be rescued lives, so that the rescue operation can be performed without delay.

[0010] An example of the configuration of the window release mechanism includes a cam member having a cam groove formed therein.
A configuration in which a pin member attached to the window frame is engaged may be considered. This can be achieved with a simple configuration of a cam groove and a pin.

[0011] More preferably, said transmission member is provided with said second member.
The position is further configured to be movable from a position to a third position that does not engage with the transmitted member, at which the window release mechanism is switched to the inactive state. According to this, the window frame is brought into the unlocked state by the movement of the transmission member, and after the window is opened, the transmission member is further moved to the third position. In this state, since the window release mechanism is inactive, the window can be fully opened manually after the transmission member opens the window by a predetermined amount (for example, half open). The windows are opened so that the rescue squad can smoothly carry out rescue operations, so the amount of opening by the window opening mechanism does not necessarily have to be fully open.

A control unit is provided for returning the transmission member from the third position to the first position via the second position after a predetermined time has elapsed from the arrival at the third position. Is preferred. According to this configuration, once the window is opened, the window is returned to the original locked state again after a predetermined time has elapsed. This predetermined time is
It is set in consideration of the time when rescue squads are likely to come. As described above, when the window is opened by mistake when returning to the original state, there is a risk that a thief may enter if the window is left open. Therefore, it is preferable to return to the original state in order to avoid such a danger.

As an example of the structure of the transmitting member and the transmitted member,
The transmitted member is a gear, and the transmission member includes a gear forming portion in which a rack gear is formed, and a non-gear forming portion in which a rack gear is not formed, and when the transmitting member is located at the first position. The gear of the transmitted member and the non-gear portion of the transmission member face each other. As described above, the configuration uses the gears, and the configuration can be simplified.

As a configuration for activating the window lock automatic opening device, after the window lock automatic opening device is attached to the space, a cover member for shielding the space is provided, and the window lock automatic opening is provided. The apparatus includes a motor for driving the transmission member, and a control unit for controlling the driving of the motor.The cover member is formed with a hole for passing a signal from a remote controller,
The motor may be configured to be activated by the signal. In this configuration, since the space is shielded by the cover member, not only the window is viewed from the outside of the building, but also the appearance viewed from the inside of the room is not impaired.
Further, it is sufficient to make a hole in the cover member so as to receive a signal from the remote controller, and the appearance can be finished to be the same as that of a normal window while incorporating a window lock automatic opening device.

The pin 22 a of the first switch 22 is pressed at the end of the rack gear 13 of the driving body 12. That is, the first switch 22 is turned on, whereby the control unit 30 can recognize that the driver 12 is at the first position. The remote control receiver 32 constantly monitors a signal (infrared light) from the remote controller 33 (Step # 10 in the flowchart), and upon receiving the signal, starts the drive motor 17 (Step # 12). When the motor 17 is started, the ball screw 18 rotates and the driving body 12
Starts moving in the direction of arrow B in FIG. Then, the first switch 22 is turned off. As the driving body 12 is moved, the rack gear 13 and the driven gear 11 come into engagement with each other, as shown in FIG. 3, thereby rotating the driven gear 11 counterclockwise. Therefore, the lock lever 4 is also integrally rotated counterclockwise (arrow A in FIG. 3). FIG. 3 shows a process of shifting from the locked state to the unlocked state.
Is defined as being in the second position.

When the driven gear 11 makes a half turn, the lock lever 4 also makes a half turn, and the state shifts completely to the unlocked state. At this time, the engagement between the rack gear 13 and the driven gear 11 has already been released. Subsequently, when the driving body 12 moves, the pin 26 is guided to the cam groove 25 this time. The pin 26 is forcibly moved by the action portion 25b of the cam groove 25 as shown in FIG.
(Arrow C in FIG. 1 (b)). Pin 2
Since 6 is integral with the second window frame 3, the second window frame 3 is also moved and the window is opened. The opening amount of the window is determined by the length of the action portion 25b. In the present embodiment, the opening amount is set to a half opening of about 10 cm.

As the driving body 12 is moved, the end pushes the second switch 23 as shown in FIG. 4, and the switch is switched from off to on. When this is detected by the control unit 30 (step # 14), the motor 17 is stopped (step # 14).
16). In this state, the window is half-open as shown in FIG. 1 (b), and the rescue squad that has arrived can further open the window and enter the room to perform rescue activities. Incidentally, as shown in FIG. 4, the pin 26 is detached from the cam groove 25 (non-operating state), so that the window frame can be opened smoothly.

Next, when the motor 17 stops, the timer circuit 31 starts operating and starts counting a predetermined time (step # 18). This predetermined time is set to a time at which the rescue squad will rush, and is, for example, 10 minutes. When the predetermined time has elapsed, the motor 17 is started (step # 20). The motor 17 is rotated in a direction opposite to the case of step # 12. Then, the driving body 1
The step 2 follows the reverse process, closes the second window frame 3 from the half-open state, and then returns the lock lever 4 to the original locked state. When the first switch 22 is turned on (Step # 22), the motor 17 is stopped (Step # 22).
