Description

[Detailed description of the invention] The present invention relates to a locking device that is attached to the opening/closing door of a building, and more specifically, the solenoid in the lock box opens and closes the contacts of the micro switch and the reed switch at the same time as the door is locked. The present invention relates to a lock device that transmits a lock state confirmation signal and activates a confirmation device such as a melody generator.

The lock attached to the opening/closing door is not just long enough to close the door dry, but also has the function of permanently closing the door so that it cannot be opened or closed freely from the outside.

To activate this book-closing function, you usually lock and unlock the door from inside the room using the thumb button. When going out, the door is locked from the outside with a key, the dead bolt is protruded, and the door is permanently closed. However, it is often the case that people forget to lock the door when going out or going to bed, and this can lead to illegal entry by third parties, which is not desirable from a crime prevention perspective.

Therefore, in the locking device of the present invention, the plunger of the solenoid moves at the same time as the locking operation for final closing, and the tip of the plunger presses the lever of the micro switch to open and close the micro switch contact, and sends a signal confirming the final closing. This is a lock device that not only makes a call, but also closes the contacts of the reed switch to operate the melody generator and play a melody.

Therefore, according to the locking device of the present invention, a melody is always played when the lock is fully closed, so it has become customary to listen to the melody, and if the lock is neglected, the melody will naturally be played. As a result, I immediately realized that I had forgotten to close and lock the door.

The lock device according to the present invention will be explained in detail below based on the drawings.

FIG. 1 is a perspective view showing the lock 1 attached to the side end of the door 2. As shown in FIG.

The lock 1 is composed of a lock box 3 and a front 4, which contain a dead drive mechanism and a latch drive mechanism.
Front 4 has dead bolt 5 and latch bolt 6
each stands out independently. Further, a thumb tongue (not shown) is provided on the side surface of the lock box 3, and a key insertion opening 51 and a lever handle 61 are provided on the opposite surface. The dead bolt 5 is locked and unlocked by rotating the thumb tongue or by inserting and rotating the key into the key insertion slot 51, and if the dead bolt 5 is pulled into the lock box in advance, the lever handle 6
By turning 1, the door can be opened and closed freely, resulting in an empty closed state.

FIG. 2 shows the internal structure of the lock box 3 through a longitudinal section, in order to explain the structure of the lock according to the present invention in more detail. According to this structure,
In order to drive the dead bolt 5, a key receiving shaft 52 provided in the lock box 3, a locking bar 53 which is pivotally supported to the lock box 3 via a pivot 56, and this locking bar 53 and a driving bar 54 are connected by a pin 55. ing. Further, the dead bolt 5 may be driven by rotation of the lever handle 61. That is, the rotation of the lever handle shaft 62 is controlled by the locking plate 5 via the pushing bar 63.
7 to drive the dead bolt 5 connected to the tip of the locking plate 57.

At this time, the latch bolt 6 is pulled into the lock box 3 by the arm 59 provided below the locking plate 57.

On the other hand, inside the lock box 3, a solenoid 8, a micro switch 9, and a reed switch 10 are arranged at appropriate locations. When the solenoid 8 is energized, the plunger 81 is attracted into the coil 82. This plunger 81 is provided with a guide pin 81a at one end, and the locking bar 5
It is slidably engaged in the long slide groove 53a provided in the slider 3.

The other end of the plunger 81 is made up of a magnet/pressing part 83 with a magnet 94 at its tip.As will be described later, when locking the dead bolt, the lever 91 of the micro switch 9 is pressed to turn it on, and the reed switch is turned on in the vicinity of the magnet 94. 10
Turn it on. In addition, in order to bundle the lead wires 11, 11, . . . of the solenoid 8, micro switch 9, reed switch 10, the wiring board 1
2 is provided.

Next, the locked state of the lock 1 according to the present invention will be explained with reference to FIG.

In the state shown in FIG. 2, by rotating the thumb tongue on the indoor side or inserting the key from the key insertion port 51 and rotating it, the key is inserted through the drive bar 54 and pin 55 as shown in FIG. axis 56
The locking bar 53 rotates in the direction of the arrow with the axis of rotation to lock the locking plate 57.

Therefore, the dead bolt 5 protrudes further from the front 4 surface, and since the locking plate 57 is locked to the tip of the locking bar 53, it is no longer possible to retreat into the lock box. When the locking bar 53 operates as described above, the plunger 81 itself is pushed out in the direction of the arrow (toward the left in the figure) while sliding the guide pin 81a of the plunger 81 upward in the long slide groove 53a.

Then, the magnet/pressing section 83 turns on the micro switch 9 and the reed switch 10.

On the other hand, when locking electrically, solenoid 8
When the coil 82 is energized by applying electricity, the guide pin 81a provided at one end of the plunger 81 and the long slide groove 53a of the locking bar 53 are engaged, so the locking bar 53 moves in the direction of the arrow about the pivot shaft 56. , locks with locking plate 57. Similarly to the above, the magnet/pressing portion 83 provided at the other end of the plunger 81 turns on the micro switch 9 and the reed switch 10.

Whether it is manual operation using a thumb button or key, or electric operation using a solenoid 8, a magnet/pushing part 83 provided at the other end of the plunger 81 is used.
presses the lever 91 of the microswitch 9, thereby opening and closing the contacts of the microswitch 9. The signal from the opening and closing of this switch indicates the fully closed state, so-called dead bolt 5.
This is a signal to confirm the locked state. Furthermore, as the magnet 94 provided in the magnet/pressing portion 83 provided at the other end of the plunger 81 approaches the reed switch 10, the magnet 9
A magnetic field will be formed between the reed switch 4 and the reed switch 10. The formation of this magnetic field causes the contacts of reed switch 10 to close. Therefore, when the reed switch contact is closed, a current flows to a melody generating device (not shown) and the melody generating device (not shown) is activated, and a melody is played.

This melody generator is composed of speakers, CMOS, etc., and operates with a voltage of about 1.5v to 15v, so a normal battery is used as the power source. Although it is possible to store the speaker inside a lock box or an opening/closing door, the acoustic effect will be significant if the speaker is attached to the outside of the door.

As described above, in the locking device of the present invention, when the lock is locked, the tip of the plunger of the solenoid presses the lever of the microswitch, opens and closes the microswitch contact, and sends a locking confirmation signal. The reed switch contact is closed, and current flows through the closed contact to the melody generator, causing the melody to be played. Therefore, you will always hear this melody when the door is locked. Therefore, if this melody is not played, the person who locks the lock should immediately confirm that the locking mechanism is not working yet.
This makes it possible to prevent people from forgetting to lock the lock, and ultimately the lock device becomes extremely practical from a crime prevention perspective.
