Abstract
ANTITHEFT APPARATUS
ABSTRACT OF THE DISCLOSURE
An antitheft apparatus has a control unit, a locking device, a lock, a vibration detector, a microswitch, a loud speaker, and a remote control. The locking device, having a solenoid which has an actuating rod at one end thereof, and a transmission rod connected between the actuating rod and a lock, allows the lock to be opened only if the solenoid thereof is actuated. The remote control is allowed to emit a door opening command to the control unit which in turn actuates the solenoid of the locking device and opens the lock. The microswitch is engaged to the actuating rod thus when the actuating rod retracts, the microswitch will respond to generate a door opening signal to the control unit. The control unit determines to actuate the loud speaker to alarm if the door opening is not from the command from the remote con-trol.

1 means 2, a lock 3, a vibration detector 4, a loud 2 speaker 5, and a remote control 6. The control unit 1 3 comprises a microprocessor, a radio receiver, and an 4 alarming circuit. The locking means 2 is used to control the lock 3. The vibration detector 4 is used to detect 6 the vibration from the door or window to which the lock 7 3 is attached. The alarming circuit of the control unit 8 1 is electrically connected to the loud speaker 5 for 9 actuating the latter to emit alarming sound when a thief invades. The remote control 6 is allowed to set 11 the whole antitheft apparatus in a guarding status 12 where the vibrating detector 4 is actuated and a 13 guarding program inside the control unit 1 is actuated 14 to serve as a commander for the sequential operation.
When the owner of the house goes out, he merely sets 16 the antitheft apparatus to the guarding status by 17 operating on the remote control 6, therefore the 18 vibration d~tector 4 starts to detect vibrations from 19 any invading action from a thief and causes the loud speaker 5 to emit alarming sound. When the owner comes 21 home, he merely operates an opening key (not shown) of 22 the remote control 6 causing the control unit 1 to 23 enable the locking means 2 to set the lock 3 to an 24 unlocked status.
Referring to Fig. 2, the locking means 2 and the 26 vibration detector 4 are installed inside a housing 10.

1 reciprocate for one cycle in the longitudinal direction 2 thereof and a transmission rod 13 connected to the 3 actuating rod 12 at the end thereof. The housing 10 has 4 a slot 100 allowing the transmission rod 13 to pass therethrough. Normally the actuating rod 12 of the 6 solenoid 11 is in a first position as shown in Figs. 2 7 and 3. However, when the solenoid 11 is actuated the 8 actuating rod 12 thereof will be retracted to a second 9 position as shown in Fig. 4. A microswitch 14 is engaged to the transmission rod 13 and controlled by 11 the latter. Normally the actuating rod 12 of the sole-12 noid 11 is in the first position. However, when the 13 solenoid 11 is actuated by the control unit 1, the 14 actuating rod 12 thereof is retracted, which in turn pulls the transmission rod 13 in a direction to the 16 solenoid 11, thereby releasing the first lock 20 as 17 shown in Fig. 4. When the transmission rod 13 is pulled 18 in a leftward direction, the microswitch 14 is 19 actuated, therefore a door opening signal is sent to the control unit l. After the control unit 1 receives 21 the door opening signal it will check whether the door 22 opening is caused by the remote control signal, if 23 positive, the guarding program of the control unit 1 24 will not actuate the alarming circuit thereof, if negative the guarding program of the control unit l 26 will actuate the alarming circuit thereof to enable the 27 loud speaker 5 to emit alarming sound.

3 The left side of Fig. 3 illustrates a schematic 4 plane view of a conventional first lock 20 which is the so-called rim lock. The first lock 20 comprises a 6 casing 200, a sliding rod 21 allowed to slide therein, 7 a socket 22 fixed to the casing 200 allowing the 8 sliding rod 21 to slide therethrough, a spring 23 9 having a first end fixed on the sliding rod 21 and a second end facing against the constant socket 22, and a 11 bolt 24 connected to one end of the sliding rod 21.
12 Normally, the bolt 24 protrudes out of the casing 200 13 of the first lock 20 as shown in Fig. 3. The bolt 24 14 will retract when it is hit by a force from outside such as when a person is closing the door, or when the 16 solenoid 11 is actuated thus pulling the transmission 17 rod 13 and the sliding rod 21 to a direction thereto 18 and causing the lock 20 to be in unlocked status.
19 The locking means 2 is also allowed to connect to a second lock 40 which is the so-called cylinder lock 21 as shown in Fig. 5. The second lock 40 has a button 22 401 to control the locked status of the lock 40, such 23 as the depressed one in Fig. 5 illustrating the lock 40 24 is in locked status. The connection between the housing 10 and the lock 40 is shown in Fig. 6, with the lock 40 26 being in an end view of Fig. 5. An external transmis-27 sion bar 402 is attached to the switching point of the 28 lock 40 and allows the lock 40 to be opened therefrom.
