Description

[Detailed description of the invention] [Purpose of the invention] "Industrial application field" This invention relates to a locking device for a window having a sliding shoji, such as a single-sliding window, a double-sliding window, and a sliding window.

``Prior Art'' Conventionally, windows in club rooms where a large number of people are accommodated and used for gatherings, which are equipped with normal single-swing windows, double-sliding windows, or lower-down windows, have locking devices that can be opened and closed by any number of people from within the room. If this is done, a large number of people may open the window and fall through the window due to negligence or their own will. Also, these days, many people use air conditioning, so it is better not to open the windows except in emergencies, and if they are opened, there may be problems due to the internal temperature control equipment, so conventional locking devices are not suitable. Since any number of people can unlock the door, it is possible to leave the window open and forget to leave it open, wasting air conditioning or disrupting the internal equipment, and the security is not sufficient to prevent theft.

This invention solves the above-mentioned problems with windows equipped with sliding shoji such as single sliding windows, double sliding windows, and hanging windows, which are always closed and cannot be opened by normal means. The purpose of this invention is to provide a locking device that can open all or a large number of windows at once in case of an emergency.

[Structure of the idea]

This device includes a latch device in which a latch and a receiver engage with each other when the sliding shoji is closed, and the latch is immovably locked from the receiver side, and a means is provided for releasing the locking by remote control. In this type of locking device, the receiver is fixed to the hard frame of the external sliding shoji and has a notch groove, and the notch groove is inserted from the opening to the opening so that the latch is pushed back when opening the internal or external sliding shoji. When the sliding shoji is closed, the latch is attached to the rigid member on the inside side along the stile of the sliding shoji with the external receiving part, and is attached to the notch groove of the receiving part. It has a spring that biases the latch in the forward direction, and an arm end that engages with a locking part provided on the side of the latch, and the base side that holds the latch in the forward position is a pivot. a spring provided so that the end of the arm urges the arm toward the latch; a link with one end connected to the middle of the arm and the other end connected to a movable piece of a solenoid; The latching device is connected to a solenoid along the rigid member, and the remote release means is a locking device which is a control device wired to the solenoid of the latching device.

[Effect]

Normally, the latch and the receiver are engaged, and even if you try to move the shoji from the movable sliding shoji side in the direction of opening the window, the latch is urged toward the receiver by the spring and engages, so that the latch does not move. The locking part and the arm end are engaged, and the latch cannot be removed from the receiver. When the solenoid is energized, the arm is pulled and disengaged from the latch, allowing the latch to be released.

``Example'' FIG. 1 is a front view of a continuous window seen from the inside.
The opening frames 1 assembled on four sides are partitioned by mullions 2, and furthermore, the spaces between each mullion 2 and between the mullions 2 and the rigid frames of the opening frame 1 are partitioned by middle crosspieces 3, respectively. The lower compartment partitioned off by the middle crosspiece 3 serves as a glass-fitting part 4.
The upper compartment partitioned by the middle crosspiece 3 has the upper frame of the opening frame 1 and the middle crosspiece 3 connected by a mullion 5, and has a glass fitting part 6 and a glass fitting part on the inside side of the opening frame 1. A single sliding shoji 7 is provided on the outside side of the opening frame 1 so that the portions other than 6 can be opened and closed. 8 is a locking device fixed to the mullion.

FIG. 2 is a front view of the locking device 8 with the cover removed (same direction as in FIG. 1), FIG. 3 is a left side view of FIG. 2, and FIG. 4 is a plan view of FIG. FIG. 5 is a plan view of the latch, and FIG. 6 is a side view of the latch.

A receiver 10 is fixed to a matching frame 9 of a single sliding shoji 7. The receiver 10 has a V-shaped notch groove 11.
is provided, and one corner is provided with a cam chamfer 13 to provide a pushing action for the latch 12.

A latch device 14 is provided on the side of the matching mullion 5. The latch device 14 has a pin 17 implanted in a bracket 16 fixed to a case 15 with a cover 15a fixed to the holding mullion 5, which is inserted into the elongated hole 1 of the latch 12.
8, and the latch 12 is inserted into the notch groove 1 of the receiver.
It is designed to be able to advance and retreat in the expected direction toward 1. The notch groove 11 of the receiver is arranged at least on the left side of the opposing groove of the notch groove 11 in FIG. The other side is gently sloping. The tip of the latch 12 has a V-shaped notch groove 11
One end of the elongated hole 18 and one of the pins 17 are in contact with each other with a slight gap between them when the latch 12 is in its advanced position, with the latch 12 being restricted from moving forward. A tension spring 21 is provided, one end of which is engaged with a pin 19 implanted in the latch 12, and the other end of which is engaged with a pin 20 fixed to the case 15. One side of the latch 12 is stepped, and this step serves as a locking portion 22. An arm 23 having an arm end that engages and disengages from the locking portion 22 is pivotally connected to the bracket 16 by a pin 24 at its base, and one end of a torsion spring 25 inserted into the pin 24 is locked to the bracket 16 side.
The other end is locked to the arm 23, and the arm 23 is biased so that the arm end faces the latch 12. A pin 28 implanted at one end of a link 27 is loosely fitted into a long hole 26 provided in the middle of the arm 23.
The other end of the link 27 is pivotally connected to a movable piece of a solenoid 29. The link 27 is slidably fitted into the round hole 16a of the bracket 16, and does not apply side thrust to the movable piece of the solenoid 29. However, if the inclination angle of the link 27 is small due to design, the round hole 16a
There is no need to provide guidance.

For example, the solenoid 29 receives a signal emitted from a smoke heat sensitive sensor such as a fire alarm.
It is wired to a control device (not shown) that drives the.

A knob 31 is fixed to the end of the arm 23. The cover 15a of the case 15 is made of metal and has an opening 32 so that the knob 31 can be operated from the outside, and a transparent acrylic plate 33 is fitted into the opening 32 with adhesive or the like.

Each figure shows the state in which the single sliding shoji 7 is locked. In this state, the latch 12 is urged toward the receiver 10 by the tension spring 21, and the latch 12 is pushed toward the notch groove 11 of the receiver.
The end of the arm 23, which is biased by the torsion spring 25, is engaged with the locking portion 22 of the latch 12, and the movable piece of the solenoid 29 is pulled up via the link 27. ing. Solenoid 29 is in a de-energized state. Therefore, when trying to open the single sliding shoji 7, the notch groove 11 of the receiver 10
tries to retract the latch 12, but the end of the arm 23 is engaged with the locking part 22 of the latch, so the latch 1
2 is not allowed to retreat and it is impossible to open the single sliding shoji 7.

When the solenoid 29 is energized via the control device by a signal from a smoke and heat sensitive sensor such as a fire alarm, its movable piece is retracted and pulls the arm 23 via the link 27. At this time, when the link 27 is tilted, a side thrust is applied, but since the link 27 is guided by the round hole 16a, the link 27 does not tilt, and the movable piece of the solenoid 29 is not broken. Since the link 27 moves the arm end in a direction away from the latch 12 against the torsion spring 25 biasing the arm 23 via the pin 28, the locking portion 22 between the arm end and the latch is disengaged. When the single sliding shoji 7 is pulled in this state, the notch groove 11 of the receiver 10 moves the latch 12 backward against the tension spring 21 that urges the latch.
Since it is removed from the notch groove 11, the single sliding shoji 7 can be moved. The latch 12 has temporarily retreated toward the latch device 14 due to the movement of the single sliding shoji 7, but once it passes the receiver 10, it is moved forward by the tension spring 21, and the end of the elongated hole 18 comes into contact with one of the pins 17, causing the stopper to close. and stops.

When the emergency situation ends and the single sliding shoji 7 is closed, the end of the latch 12 comes into contact with the cam chamfer 13 of the receiver, and the tension spring 21 is activated by the cam chamfer 13 and the slope of the end of the latch 12.
is pushed toward the latching device 14 against the The end of the latch 12 passes over the receiver 10 and is advanced by the tension spring 21 to engage the notch groove 11 of the receiver. Thereupon, the power supply to the solenoid 29 from the control device (not shown) is cut off. When the solenoid 29 is deenergized, the torsion spring 25 rotates the arm 23 in the direction in which the arm end faces the latch 12 , the arm end engages with the locking part 22 of the latch, and the solenoid 29 is movable via the link 27 . The piece will be in a pulled up state.

In case of an emergency, the acrylic plate 33 of each window can be broken to reveal the knob 31. When the knob 31 is pushed down, the arm 23 is pushed down around the pin 24 against the torsion spring 25, and the end of the arm separates from the locking part 22 of the latch, so that the single sliding shoji 7 can be opened. In this case, when you open the single sliding shoji 7, the latch 1
2 moves forward, and the arm 23 moves its end toward the latch 12 by the torsion spring 25 and engages with the locking part 22 of the latch, so that the latch 12 cannot return. Therefore, when each window is opened, the solenoid 29 is energized to keep the arm 23 in a downwardly rotated state before closing.

In the embodiment, a continuous window has been described in which the inside side is a fitting part and the outside side is a single sliding shoji, but it may also be provided so that it can be locked between the open end side hard frame of the mullion 2 and the single sliding shoji 7. Generally, when the sliding shoji is closed, the stile of the sliding shoji on the outside and the mullion and jamb along the stile (windows with horizontal sliding shoji such as single sliding windows and sliding windows) It is installed between members such as the middle crosspiece, upper and lower crosspieces (upper and lower windows), etc.

Although the embodiment describes the application to a single sliding window, it can also be applied to a sliding window, a sliding window, etc., and is generally applicable when a sliding shoji screen is provided.

[Effect of idea]

This device includes a latch device in which a latch and a receiver engage with each other when the sliding shoji is closed, and the latch is immovably locked from the receiver side, and a means is provided for releasing the locking by remote control. Since the locking device is constructed as described above, the window cannot be opened all the time, so it is less likely that a person will fall, and there will be no need to open the window unnecessarily and damage the air conditioning. Also, in case of an emergency, the entire window can be opened, but even if the shoji side is biased in the opening direction from the closed position, the spring biases the latch toward the receiver. , the latch moves forward so that the latch and the receiver engage and move the shoji in the direction of closing, or the latch is urged in the forward direction by the spring force, so the latch's latch and the arm end are not pushed strongly. The force of the solenoid allows the arm end and the locking part to be easily disengaged, which has the effect of ensuring that the window opens. In this embodiment, individual windows can be opened by each person in case of an emergency.
