TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lock receiver that issues an alarm without opening the door when a force exceeding a certain level is applied to the lock receiver when the door is opened.
[0002]
[Prior art]
The technology to detect the opening of the door locked by the conventional technology is to provide a lock confirmation switch and a door open / close confirmation switch on the lock body, and to open the door when the door open switch is turned on while the lock switch is on. It is just what you judge.
[0003]
[Problems to be solved by the invention]
In the related art, when the lock key or the thumb turn is turned while the door is opened and the dead bolt is protruded, the lock switch of the lock is turned on, and the door open switch of the lock is turned on because the door is open. In other words, it is determined that the copier is opened even when the original copier is not opened.
Further, when the copier is opened in a locked state, the copier opening is successful, and the door opening signal transmitted after the door is opened is determined to be the copier opening, so that the security effect is small. Even if you receive an alert after the Koji is opened, when the guards arrive at the scene, the thief will have finished work and returned.
If you open the door, you will be warned before the door is opened, and the lock will be strong until the door is opened. No thief keeps trying to open the stomach when the alarm sounds, knowing when to open the stomach successfully.
[0004]
[Means for Solving the Problems]
The method of judging the opening is based on sensing how much force is applied between the lock receiver and the dead bolt in the direction in which the door opens. What senses this is a bumper combined with the receiving hole of the lock receiver. When the bumper is crushed, bent, or slid, it is determined that the bumper is opened. It is a mechanism that the bumper or deadbolt operates the switch to know the open state of the bumper. Even if the bumper is crushed or bent, the strength of the lock receiver is made higher, so there is no damage to the lock receiver, and an alarm can be issued without opening the door.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Description will be made based on the drawings. The cross sections of the door and frame are painted black for easy viewing. FIG. 2 is a perspective view in which an opening alarm lock receiver is attached to a frame. FIG. 1 is a perspective view in which the door is closed and locked on the frame. FIG. 3 is a cross-sectional view taken along the line AA in FIG. 1. A is a normal state, B is an open state, the bumper (14) is bent, and the pusher (22) of the alarm switch (21) is pressed to turn on the alarm switch. Is shown. In this state, the lock receiving body (17) is not damaged, and can withstand the opening of the stiffness even after this.
When the thief starts to open the locked door, when the alarm bell sounds and the light turns on, it is impossible to continue the open operation without knowing when the open operation will be completed. When the bell rings, you need to escape before the guards run. I can't keep working on the opening while worrying while the bell is ringing. Even if the bell rings, the door does not open, which can serve the purpose of crime prevention.
[0006]
FIG. 4 is a perspective view from the rear of the torsion cover (18) of the squeezing alarm lock receiver, with one side thereof being removed so that the inside can be seen. “A” is a set of an alarm locking alarm receiver. B is a view in which the squeezing strike (11) with the bumper (14) is separated from the lock receiving body (17). The bumper may be attached to the lock receiving body, or may be provided on a strike for opening as shown in the figure and combined with the lock receiving body. FIG. 6 shows a modification in which the bumper (40) is provided on the lock receiving body (38). FIG. 7 shows a modification in which the bumper (46) is provided on the toro cover (44).
FIG. 9 is a view in which an opening strike (59) slides, and FIG. 10 illustrates a sliding mechanism. The mechanism is divided into the lock receiving body (58) and the squeezing strike (59) and screwed to the frame and attached. When pressure is applied in the opening direction of the door, the slide is provided in the screw hole (68) of the stiffening strike. The screw is inserted into the groove (69), and the strike for opening the edge slides against the lock receiver.
FIGS. 1, 5, 6, and 7 show a case where the bumper presses the pusher of the opening alarm switch, and FIGS. 8 and 9 show a case where the dead bolt presses the pusher. If the pusher is pushed with a deadbolt, the pushing force will be lost if the pressure for opening the cohesion disappears, and the alarm transmission will stop.
[0007]
In addition, when a switch for locking confirmation is additionally mounted on the lock opening alarm lock receiver, a lock confirmation switch (23) may be additionally mounted in the lock receiver as shown in FIGS. The lock confirmation switch is a conventional technology with a conventional switch strike. When the lock is locked, the switch provided on the back of the lock receiver is pressed by the dead bolt, and the switch is turned on to emit a signal. Locking and unlocking are determined by whether the dead bolt (19) is in the receiving hole of the lock receiver. By adding a switch, it is possible to obtain confirmation of unlocking and confirmation of opening of the cogs from a single lock receiver.
FIG. 12 illustrates a lock receiver according to claim 2 which has a battery and a buzzer in addition to an alarm switch for opening the cog. The battery and the buzzer need only be integrated with the lock receiver, and may be assembled above, below, or beside the lock receiver. You have the opportunity to open it once a year or not, and you don't have to worry about battery drain.
The reason why a battery or buzzer is not incorporated in a conventional switch strike that takes a signal from a lock receiver is not seen because of a switch that knows a locked state or an unlocked state. The lock is always in the locked state or the unlocked state, and since the state is always continued, the battery is quickly consumed, so it is impossible to use the battery as the power supply.
The alarm opening alarm lock holder having the battery (75) and the buzzer (76) according to the second aspect works only when the ironing is opened. Therefore, if the ironing is not opened, the battery may be changed once every two to three years. In addition, since there is no need for wiring, it can be used in place of an existing lock receiver, which is very useful. Although it is possible to output a signal to the outside, even if it does not output, the thief thinks that the signal may have gone to the outside if the alarm sounds, gives up opening the koji and escapes, which is very high crime prevention.
If the battery is opened, the buzzer continues to sound until the battery runs out, so it is necessary to remove the lock receiver and replace the battery. If the lock receiver is replaced without removing the lock receiver, the battery case needs to be provided at a different position from the lock receiver, and a frame and a wall need to be processed.
[0008]
【The invention's effect】
In the conventional koji opening signal and the door opening signal, when opening the koji of a door locked by a thief, an alarm sounds after the koji opening is successful and the door is opened. Therefore, it is possible for a thief to quickly search the room and escape.
When the thief starts to open the door of the door to which the door opening alarm lock receiver of the present invention is attached, an alarm sounds when the bumper is bent. At that time, the lock receiver itself was not damaged. The thief can not continue to open the Koji while the alarm is sounding and gives up opening and runs away. Therefore, the security effect is great.
To recover a bent bumper, use a pair of pliers to bend the bumper back, or simply open the strike and replace only the strike with a new one.

Description by tablet type.
Locks include a permanent lock having only a deadbolt, an unlockable empty lock having only a latchbolt, and a general entrance lock having a deadbolt and a latchbolt. As a special example, there is one in which a latch bolt is fixed and serves as a dead bolt.
The KOJI open alarm lock receiver is not used for empty locks that cannot be locked.
Used for dead bolts and those that function as fixed dead bolts.
If a lock has a dead bolt and a latch bolt, a lock receiver provided with a bumper for both is used. The reason is that if a bumper is not provided for the latch bolt, the latch bolt is first broken in a normal latch bolt receiving hole when the coping is opened. If the width of the latch bolt receiving hole is set to be large, the backlash of the door becomes large at the time of normal closing.
