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 status, 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.
An actuating piece 6 is connected to a crescent lock 5 attached to one side of the door frame 3, and the actuating piece 6 is connected to an indicator 9 provided on the door opening frame 7 to indicate the rotation of the crescent lock 5. At the same time, the water draining piece 1 of the other door frame 4 is applied to the door frame 3.
A lock fitting 16 that can be brought into contact with 2 is attached.
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. The sliding groove 22 is slid in the front-rear direction parallel to the door opening frame 7. The door frames 3 and 4 are formed by rectangularly arranging a frame material 23 having a substantially Japanese-shaped cross section, and a glass plate 24 is filled in the groove of the frame material 23 through a groove provided on the opposing surfaces. Vertical frame members 2 are fitted using watertight material and are adjacent in the closed state.
3a and 23b have an L-shaped draining piece 11 with bent pieces 27a and 27b provided at the tips of base pieces 26a and 26b that are perpendicular to the faces on the opposite sides,
12 is provided protrudingly, and when the door frames 3 and 4 are in the closed state,
Water is drained by fitting the bent pieces 27a and 27b into each other.

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 within the box body 29, and the arm 39 is attached to the connecting rod 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. 41. In addition, the vertical frame material 23
A vertically continuous slit is provided on the side surface of a, and an elongated hole 43 is bored in the box body 29, into which a pin 42 that connects the tip of the connecting rod 41 and the actuating piece 6 slides. When rotating and locking, 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 lock fitting 16 includes a pressing piece 47 that is horizontally slidably supported by the base piece 26a, and a pressing piece 47 that is slidably supported horizontally by the base piece 26a.
L-shaped locking piece 4 provided integrally and at right angles to the
6, and the locking piece 46 is connected to the hole 48 of the box body 29.
It is inserted into the box body 29 through. Also, the actuating piece 6
In this example, an engaging portion 37 consisting of a notch hole is formed, and the locking piece 46 is engaged with the engaging portion 37 by moving forward, so that the upper and lower portions of the actuating piece 6 restrain movement. Further, the pressing piece 47 has a contact piece 49 at its protruding end, and protrudes toward the bent piece 27b of the draining piece 12 of the other door frame 4. Further, the lock fitting 16 is biased forward by a spring 50 inserted into the pressing piece 47 so that the locking piece 46 locks into the engaging portion 37. Therefore, the locking piece 46 is normally urged forward and restrains the actuating piece 6, but when the piece 49 is pressed by the bent piece 27b, the locking piece 46 moves back and can release the restraint. .

The switch S is, for example, a limit switch, and has its operating end exposed through an insertion hole 51 provided in the sliding groove 22 of the door opening frame 7, and 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 switch S detects the operation when the actuating piece 6 rises and comes into contact with it, and the crescent lock 5 rotates. can be detected.

The indicator 9 is, for example, a pilot lamp, and as shown in FIG. 3, is connected in series to each switch S of a plurality of sliding doors 2 to which the locking device 1 of the present invention is employed.

However, in the locking device 1 of the present invention, when the door frames 3 and 4 are in the open state, the locking piece 46 of the lock fitting 16 engages with the engaging portion 37 and locks the actuating piece 6, thus locking the crescent lock. In order to prevent rotation of the crescent lock 5, the receiving metal fitting 32 is separated from the crescent lock 5.
The crescent lock 5 is prevented from rotating in the released position. Note that only in the closed state where the contact piece 49 is in contact with the bent piece 27b, the locking piece 46 is
Lifting of the actuating piece 6 is permitted. The switch S detects the rise of the operating piece 6 as described above, and the indicator 9 lights up only when all the sliding doors 2 are closed, so that the locked status of all the sliding doors 2 can be seen at a glance from a remote location. You can check it.

As mentioned above, the locking device of the present invention has an actuating piece that moves up and down in conjunction with the crescent lock, and the indicator can only be activated when both door frames are securely closed by the lock fittings, and as a result, the locking device is activated. This prevents forgetting to lock the sliding door, improves the crime prevention effect, and prevents the indicator from operating in the unlocked state, making it possible to visually confirm whether the sliding door is locked reliably and safely.

In addition, in the locking device of the present invention, the actuating piece is formed to move downward by the rotation of the crescent lock, and the actuating piece is formed using a small piece located only at the upper end of the door frame, and the arm is flexible. It can also be configured to be linked using wires,
Furthermore, 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 an operating piece instead of a micro switch.
