Description

[Detailed Description of the Invention] The present invention relates to a locking device that can remotely check the locked state of a sliding door using a crescent lock, prevent forgetting to lock the door, and improve the safety and crime prevention of a house.

Conventionally, crescent locks have been equipped with identification pieces that protrude when the lock is locked to confirm the locked state, but this requires a lot of effort as it requires going around each lock one by one and checking visually. If you forget to check other things, it becomes unsafe.

This invention is based on the use of an operating piece that moves up and down with the rotation of the crescent lock.
The object of the present invention is to provide a locking device that can remotely confirm the locked state of a door provided in an opening such as a window and improve crime prevention and safety.One embodiment of the present invention will be described below with reference to the drawings.

In the figure, the locking device 1 of the present invention is a sliding door 2.
A first switch S1 operated by an operating piece 6 linked to a crescent lock 5 attached to the side of one door frame 3, and a second switch S2 operated by a protruding piece 13 of the other door frame 4 are connected in series. The device indicates that the lock is locked by the connected display device 9, and the first and second
The switches S1 and S2 are attached to a door opening frame 7 provided on the wall of the house. The sliding door 2 has the one door frame 3 and the other door frame 4 located on the indoor side, and the upper ends of the door frames 3 and 4 are provided on the frame material 21 above the door opening frame 7. Slide the sliding groove 22 back and forth. The door frames 3 and 4 are made by arranging frame members 23 having a substantially Japanese-shaped cross section in a rectangular shape, and a glass plate 24 is filled in the groove portion in front of the frame members 23 by grooves provided on opposing surfaces. The vertical frame members 23a, 2 are fitted using watertight material, and in the closed state, the adjacent vertical frame members 23a, 2
3b has L-shaped draining pieces 11, 1 on their facing surfaces that drain water by fitting into each other.
2, while the outer vertical frame member 23 of the door frame 4
d has the protruding piece 1 facing outward at its upper end.
3 is installed protrudingly.

The crescent lock 5 is pivoted on the outer surface of a box body 29 attached to the side surface of the vertical frame member 23a, and its rotation reduces the radius length and gradually increases the height of the locking wall 3.
0, and by engaging with the hook portion 33 at the tip of the receiving metal fitting 32 provided on the vertical frame member 23b, the door frame 3,
4 can be pulled in while pushing in the opposite direction. An arm 39 is attached to the protruding end of the support shaft inside the box, and the arm 39 connects the connecting rod 41 to the operating piece 6, which is loosely inserted into the groove at the rear of the vertical frame member 23a so as to be movable up and down. connected via. In addition, the vertical frame material 23a
A vertically continuous slit is provided on the side surface of the box body 29, and the connecting rod 41 tip and the actuating piece 6 are provided in the box body 29.
An elongated hole 43 is drilled through which a pin 42 connecting the crescent lock 5 slides, so that when the crescent lock 5 is rotated and locked, the actuating piece 6 can be raised. The actuating piece 6 is made of a long channel member, and when the crescent lock 5 is in the unlocked state, its tip is approximately aligned with the upper frame member 23c, and therefore, when the crescent lock 5 is rotated, the upper frame member 23c is aligned. Frame material 23
protrudes from c.

The first and second switches S1 and S2 are limit switches, for example, and the first switch S
1 is an insertion hole 51 provided in the sliding groove 22 of the door opening frame 7
Its operating end is exposed, and it is housed and fixed in a recess provided in the wall. The insertion hole 51 is opened at a position above the actuating piece 6 when one door frame 3 is in the closed state, and the first switch S1 is activated when the actuating piece 6 is raised.
The operation can be detected by contact, and the rotation of the crescent lock 5 can be detected. The second switch S2 is a vertical frame member 25 of the door opening frame 7 facing the protruding piece 13.
is attached to the back of the frame, and its operating end is connected to the vertical frame member 2
The protrusion 13 provided in the main body 5 faces a through hole 26 through which the protrusion 13 can be inserted, and is pressed by the protrusion 13 entering from the through hole 26 to operate.

The display device 9 is, for example, a pilot lamp, and as shown in FIG. 3, the display device 9 is a pilot lamp, and as shown in FIG. They are connected in series.

However, the locking device 1 of the present invention has a crescent lock 5.
The actuating piece 6 can rise only when the door frame 3 is rotated, and the actuating piece 6 passes through the insertion hole 51 only when the door frame 3 is in the closed position.
is detected. Furthermore, the second switch S2 is set to the door frame 4.
Detects the closing of the first and second switches S.
1. S2 is connected in series to the display device 9, so that the display device 9 lights up only when all the sliding doors 2 are locked, so that the locked status of the sliding doors 2 can be confirmed at a glance from a remote location. can.

As mentioned above, the locking device of the present invention has an operating piece that moves up and down in conjunction with the crescent lock, and an indicator that operates by a protruding piece, and can prevent forgetting to lock the lock, and has a crime prevention effect and safety. improve.

Further, the actuating piece is connected to an arm provided on the support shaft of the crescent lock via a connecting rod, so that operation of the actuating piece is ensured. Furthermore, the actuating piece is provided on one door frame with the crescent lock and the lug on the other door frame, so that the indicator is only illuminated when both door frames are correctly closed and the crescent lock is locked. This ensures that the door frame is locked. Furthermore, since the first and second switches are used and connected in series, the possibility of malfunction due to switch failure is reduced. The locking device of the present invention can be modified in various ways, such as by using a reed switch that detects the approach of the operating piece.
