It is a figure which shows one embodiment of the internal structure of the crescent applying and unlocking device of the present invention. It is a figure which shows one embodiment of the motivation provision means which comprises the crescent application and unlocking tool of this invention. It is a figure which shows an example of the existing conventional crescent.

The crescent application / unlocking device according to the present invention comprises a rotatable handle pushing piece that contacts and pushes the handle of the crescent, a driving means for rotationally driving the same, and a motive for operating the driving means in an emergency or the like. Motivating means for giving and a housing for housing them. Details will be described below.

FIG. 1 is a view showing an embodiment of a crescent applying / unlocking device according to the present invention.
1-A is intended specifically for unlocking, and 1-B is intended for both locking and unlocking. Here, a rotatable handle push piece 110 that contacts and pushes the crescent handle and a housing 120 that houses the handle push piece 110 are shown.
Inside the housing 120, there are built in a driving means for rotationally driving the handle pushing piece 110 and a motivating means for giving a motivation for operating the driving means in an emergency or the like. Of course, these may be configured to be visible from the outside of the housing 120 or may be external.
In 1-A, the housing 120 has a screw hole 130 and a mounting tool 130 such as a screw to be attached later to the pulling-up cage, and the outer surface of the housing 120 is opened to form an opening 140. From there, a crescent hook comes out and can be fitted into the hook receiver.
The handle pushing piece 110 is rotatable around the rotation shaft 150. In addition, in this figure, although the guide groove 160 along the case where the handle pushing piece 110 rotates is shown, it does not stick to this. The handle pushing piece 110 has a groove 111 on the side where the crescent handle is pushed. A handle is fitted into the groove 111, but the groove 111 may not be provided as long as the handle can be pushed by the handle pushing piece 110.
In 1-B, the direction of the groove 111 of the handle pushing piece 110 is different from 1-A.
Since the opening direction of the groove 111 is perpendicular to the rotation direction of the handle pushing piece 110, in this case, the handle fitted in the groove 111 is in both directions of rotation of the handle pushing piece 110, that is, both locking and unlocking directions. Can move. On the other hand, in 1-A, only one of them, in particular, unlocking is possible.

FIG. 2 is a view showing an embodiment of a state in which the crescent applying / unlocking device of the present invention is attached to an existing crescent.
At 2-A, the crescent handle 210, the crescent hook 220, and the hook receiver 230 are shown. As described above, the hook receiving member 230 is attached to an upright stand on the outdoor side.
The handle 210 and the crescent hanging piece 220 are set so as to be taken into the casing 120, and the casing 120 is attached to a vertical shaft on the inside of the mounting chamber by a fixture 130. The state 1-A is a locked state, and the hook piece 220 is fitted in the fitting groove 231 of the hook receiving member 230.
From this state, when the handle pressing piece 110 rotates clockwise when necessary, the handle 210 is pushed, so the handle 210 also rotates, and the hooking piece 220 is also removed from the fitting groove 231 and unlocked.

In 2-B, it is better that the rotation axis of the handle 210 and the rotation axis of the handle pushing piece 110 are on the same straight line (same axis state) so that the above operation is easy. In this way, it is possible to keep the handle 210 and the handle pushing piece 110 in close contact from the beginning to the end of the rotation.
If the axes are different, only part of them will touch and push. Further, in the same axis state, it is necessary to arrange the space between the handle pressing piece 110 and its rotating shaft with a gap so as not to interfere with the handle 210 and the hanging piece 220. For this purpose, the handle pressing piece It is necessary that 110 bends in front of the hanging piece 220 and extends to the outside of the hanging piece 220 and extends to the position of the same axis.
This is why the section from the handle pushing piece 110 to its rotating shaft is bent as shown in the figure.

FIG. 3 is a view showing another embodiment of the crescent applying / unlocking device of the present invention.
The same can be said for 1-A and 1-B in FIG. 1, but taking the case of 1-A as an example, if only the changed part is used, in 3-A, the side of the guide groove 160 attached to the flange is cut and opened. It is what. If it becomes like this, it will be easy to construct at the time of attachment.
In 3-B, a protective rod 310 is provided so as to hide the handle pushing piece 110 from the housing 120. Even if the protective rod 310 is not provided, the portion of the housing 120 with the attachment 130 is located between the outer side and the handle pushing piece 110 so as to hide it. When there is the protective rod 310, it is difficult to further turn the handle pushing piece 110 from the outside. Therefore, it is difficult to turn the handle 210 as a matter of course. Note that the protective casing 310 and the casing 120 shown in the figure constitute a shield that shields the handle pushing piece from the outside.

FIG. 4 is a diagram showing an embodiment of the internal structure of the crescent applying / unlocking device of the present invention.
FIGS. 1 to 3 explain the drive means for rotationally driving the handle pushing piece 110 and the motivating means for providing the motivation for operating the drive means in an emergency or the like, which are the structures of the crescent application / unlocking device. There wasn't. This is explained here.
Any example may be used, but first, the drive means will be described by taking the handle pushing piece 110 shown in 2-B of FIG. 2 as an example. In 4-A, the stop pin fitted to the rotating shaft is pulled out by driving the motor, and the rotating shaft is unlocked by urging of the spring. In 4-B, the rotation of the motor is transmitted by a gear and opened. This is the case for locking.
First, in 4-A, the illustrated state is a locked state. It is assumed that unlocking is performed from this state. The rotating shaft 410 that rotates the handle pushing piece 110 is biased to rotate in the unlocking direction by a first biasing means 420 such as a spring. For this reason, one end of the biasing means 420 is fixed to the rotating shaft 410 and the other end is fixed to the housing 120 side. Further, the rotation shaft 410 is provided with a stop hole 430.
A slide body 440 having a stop pin 441 that fits in the stop hole 430 is slidably supported by a slide base 450 fixed to the housing 120. The slide body 440 has a plane gear 460, and a gear 480 that transmits rotation from the motor 470 is engaged with this. Note that the gear 480 is notched so that it contacts the plane gear 460 by about 1/4, and the others do not contact. The slide body 440 is urged against the slide base 450 by a second urging means 490 such as a spring so as to be pushed toward the rotating shaft 410.
In the locked state, the pin 441 fits into the stop hole 430 (in the drawing, it is drawn so as not to be easily understood but is fitted in the locked state), and the handle pushing piece 110 is pressed so as not to unlock. It has been. From such a state, when an instruction to rotate the motor 470 is given from a motivating means for giving a motivation for operating a driving means (not shown), the slide body 440 rotates to move the pin 441 out of the stop hole 430. As a result, the rotating shaft 410 urged by the urging means 420, and thus the handle pushing piece 110, and as a result, the handle rotates in the unlocking direction and enters the unlocked state. Since the gear 480 is cut out of 3/4 so as to contact the plane gear 460 by about 1/4, the contact is lost immediately, the rotation of the motor is not transmitted, and the slide body 440 is not restrained. The second urging means 490 moves the pin 441 toward the rotating shaft 410 and comes into contact therewith.
Since the rotation of the motor 470 may be stopped in this state, it may be stopped when the pin 441 comes out of the stop hole 430, stopped when the pin 441 returns again, or the rotation of the motor is stopped by one rotation using a pulse motor. If it does in this way, according to the strength of the 1st biasing means 420, it can rotate instantaneously and can be unlocked. The degree of notch is not limited to 3/4 but can be changed as necessary as a design matter. Of course, other means for transmitting rotation from the motor can be used. In this example, since the biasing force by the first biasing means 420 is the unlocking direction, once the unlocking is performed, the handle is pushed by hand unless the handle and therefore the handle pushing piece 110 are returned to the locking side manually. The piece 110 is on the unlocking side.
Of course, if the pin 441 is driven by other mechanical means, it can be performed not only by the electric drive by the motor.

In 4-B, the gear 480 transmits the rotation from the motor 470 in contact with the gear 431 attached to the rotary shaft 430 with the handle pushing piece 110. The transmission between the gear 480 and the motor 470 may be a direct connection or via a plurality of gears. The motor 470 is driven to rotate when required by a command from the motivating means. As a result, the rotating shaft 430, and thus the handle pushing piece 110, is rotated via the gear 431, and a handle (not shown) is rotated to be unlocked. Since the gear 480 is the same as the case of 4-A and about 3/4 is missing, when the rotational force is not transmitted, only the handle pushing piece 110 is returned to the locking direction by the third urging means 421. In the return state at that time, the stop pin 432 attached to the rotating shaft 430 hits the blocking plate 433 fixed to the housing 120 and stops. The position corresponds to the locking position.
The handle is unlocked without returning. In order to stop the motor 470 by detecting the rotation of the rotating shaft 430, the rotating shaft 430 is provided with a permanent magnet 434, and the sensing position is provided with a magnetic sensor 435 and the like. Therefore, when the rotating shaft 430 rotates 90 degrees or more, the motor 470 stops rotating, and at the same time, the handle pushing piece 110 moves to a return operation. Such an operation is a simple operation, but may be performed via a control device. In that case, it is natural that the rotation detection can be omitted and the necessary rotation can be instructed from the control device. In addition, although 4-A and 4-B used electric rotation operation like motor drive, when performing electric operation, naturally the power supply which drives these is naturally required.

In addition, it can also be performed only by mechanical operation, not electrical operation. For example, in the case of 4-A, the rotation operation of the handle pushing piece 110 in the unlocking direction can be performed by the urging of the first urging means 420, so that the operation of pulling out the pin 441 from the retaining hole 430 is mechanically performed. For example, other driving means such as a motor and gears can be eliminated. For that purpose, in order to pull out the pin 441, it is only necessary to feel the vibration and pull out the pin 441. For example, with a pendulum that resonates with vibrations, this gives a movement that moves in one direction like a ratchet, tells this as a pull-out action of the pin 441, thereby causing the pin 441 to come off, By pulling and dropping the weight by the moving operation, means such as allowing the pin 441 to come out by dropping the weight is possible. In this case, the motivating means is from the moving operation for performing the pin 441 to the means for feeling the vibration. Further, if the rotary shaft 430 is pulled and rotated with the string connected to the weight due to the fall of the weight, it is natural that the electric drive can be made unnecessary even in 4-B, and various forms can be taken.

Although the motivating means has been described in the above description, this will be described in detail with reference to FIG.
FIG. 5 is a view showing an embodiment of the motivating means constituting the crescent applying / unlocking device of the present invention.
Since the driving means 5100 is a means for rotating the handle pushing piece 110 in the locking or unlocking direction, the first biasing means 420 for biasing the rotary shaft 430 described so far to the motor 470 or a pin The extracting means 441 corresponds to this. A means for giving a motivation for moving these driving means 5100 is a motivation giving means 5200, and the motivation giving means 5200 captures an emergency alarm or processes for outputting a drive signal for driving a driving means by capturing a vibration. There are means to perform, that is, (1) by electrical sense, or (2) mechanical motivation means by mechanical sense described in the previous paragraph. In special cases, (3) it can be driven manually.
First, according to (1) electrical sense, the wireless receiving means 5212 receives emergency disaster information such as the occurrence of an earthquake or receives a broadcast wave via an antenna 5211. This is received by the control means 5213 to drive the drive means 5100. Note that the driving unit 5100 can be driven by the remote controller 5214 via the infrared receiving unit 5215 and the control unit 5213.
Emergency disaster information such as the occurrence of an earthquake informs the extent and time of the earthquake by the P wave of the earthquake, so it is convenient to be able to complete the unlocking process before the actual S wave of the earthquake arrives. Good.
(2) The mechanical motivating means based on the mechanical sense has been described in the previous paragraph and will be omitted.

In the above description, a rotating motor is taken as an example of the driving means. However, if a linear motor or an electromagnet that moves the rod is used, a gear or the like is not necessary to remove the pin.
Various actuators can generally be used.

Since the crescent application / unlocking device of the present invention is configured as described above, it can be retrofitted around the existing crescent and the crescent handle can be forcibly rotated and applied / unlocked. The crescent in the above state can be applied and unlocked, particularly in the event of an emergency, making it possible to contribute to prevention of confinement and breakage of the window glass, which is advantageous and has great industrial applicability.
