[0021]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0022]
As shown in FIG. 1, the remote control lock in this form includes a remote control lock body 10 and a wireless remote control 50.
[0023]
The remote control lock body 10 has a shape in which a locking portion 12 is provided on a main body case 11, and a display panel 43 is provided on the exposed portion of the hook portion 12 b of the locking portion 12 on the outdoor side, as will be described later. It has been.
[0024]
The main body case 11 is made of a partially transparent plastic. Inside the case 11, as shown in FIG. 2, a bolt 14, an actuator 15, a sensor switch 16, a pressure detecting means 17 and an alarm generating means 18 thereof. (FIGS. 3 and 4) and a circuit board 19 and a battery B are incorporated.
[0025]
The bolt 14 is accommodated in the guide hole and is supported so as to freely advance and retract. A rack gear is formed on the side of the bolt 14, and this rack gear faces a slit provided in the guide hole. Further, the pinion gear 20 of the actuator 15 meshes with the rack gear of the bolt 14 through this slit.
[0026]
That is, the actuator 15 has a configuration in which a reduction mechanism is provided in the motor M, and a clutch is provided in the reduction mechanism.
[0027]
The speed reduction mechanism is a combination of a worm gear, a spur gear, and a pinion gear. When the motor M rotates, the rotation is transmitted in the order of worm gear → spur gear → clutch → pinion gear 20 so that the speed can be reduced.
[0028]
The clutch is a friction clutch using a member such as a rubber plate, and when a predetermined rotational force is applied to the pinion gear 20, the clutch can slide to rotate the pinion gear 20. Even when the actuator 15 does not operate, it can be unlocked by pulling down the pull-down rod S of FIG.
[0029]
In this embodiment, the sensor switch 16 has two micro switches engaged with the projecting piece 21 attached to the bolt 14 so that the position of the bolt 14 can be detected (top dead center and bottom dead center). Each switch output is connected to a microcomputer 30 to be described later.
[0030]
As shown in FIG. 3A, the pressure detecting means 17 uses a spring 22 and a switch (for example, a micro switch) 23, and the spring 22 is, for example, as shown in FIG. , One is hung on the shaft and arranged on the side of the bolt 14, and the other is provided with a switch 23 so that the switch 23 operates when the spring 22 is bent as indicated by the arrow due to the pressure of the bolt 14. It is.
[0031]
This switch is connected to the alarm generating means 18 as shown in FIG. The alarm generating means 18 is composed of an off-delay timer (or a one-shot trigger circuit or the like), a buzzer driving circuit, and a buzzer. When the switch is turned on even for a moment, the off-delay timer is activated to operate for a predetermined time. A buzzer sounds, and these circuits are provided on a circuit board 19 described below.
[0032]
As shown in FIG. 4, the circuit board 19 is composed of a main board MB and a sub board SB. In addition to the alarm generating means 18 described above, the main board MB includes a driving means 31, an informing means 32, a first board. The voltage detection means 33, the second voltage detection means 34, the power supply means 35, the ID identification means 36, and the buzzer drive circuit 37 are provided. Further, the sub board SB includes a circuit of the wireless reception unit 38 that needs to be adjusted.
[0033]
Specifically, the main board MB realizes the above respective means (circuits) by connecting an interface circuit to a microcomputer (one-chip microcomputer with a halt and timer function) 30.
[0034]
For example, the drive circuit 31 is a circuit in which a forward / reverse circuit using transistor bridge connection is connected to the microcomputer 30 via a drive IC, and the motor M of the actuator 15 is forward / reversely rotated by the output of the microcomputer 30.
[0035]
In this embodiment, the notification means 32 is an LED connected to the microcomputer 30 via a current limiting resistor, and can be turned on and off directly by the output of the microcomputer 30.
[0036]
The first voltage detection means 33 uses a power supply voltage monitoring IC having a predetermined reference voltage, here 2.6 V, and is connected to the microcomputer 30 to connect the voltage of the battery B. When the voltage falls below the reference voltage of 2.6 V, a detection signal is input to the microcomputer 30.
[0037]
The second voltage detection means 34 uses an IC for power supply voltage monitoring with a reference voltage of 2.4V. When the voltage of the battery B falls below the reference voltage 2.4V, a detection signal is sent to the microcomputer 30. Output.
[0038]
Here, the reason why the reference voltage of the second voltage detecting means 34 is set to the voltage 2.4 V is that it is set in accordance with the minimum driving voltage of the motor M for accommodating the bolt 14, and the characteristics of the motor M, etc. Is appropriately determined.
[0039]
The power supply means 35 intermittently supplies power from the battery B to the wireless receiving means 18 of the sub-board SB, which will be described later, and the microcomputer 30 controls on / off of the switching transistor connected to the battery B. By doing so, the power supply to the wireless receiving means 18 is controlled. Thus, the wireless receiver 18 is operated intermittently without always being in a standby state, thereby suppressing the consumption of the battery B.
[0040]
In this embodiment, the ID identification means 36 is composed of a ROM memory 36a connected to the microcomputer 30 and a setting dip switch 36b, and an ID code is stored in the ROM memory 36a. When an address is set by the setting dip switch 36b, the microcomputer 30 reads the ID code of the set ROM memory 36a and identifies the wireless remote controller 50 based on the ID code. .
[0041]
Reference numeral 37 in the figure denotes a buzzer drive circuit that emits a confirmation sound or issues an alarm when an abnormality occurs.
[0042]
On the other hand, as shown in FIG. 5 (a), the locking portion 12 is a hook-like one that is hung on the upper portion of the door, and is composed of a main body attaching portion 12a, a hook portion 12b, a connecting plate 12c, and a stopper piece 12d. Thus, an adjuster mechanism that can adjust the opening of the hook in accordance with the thickness of the door is provided.
[0043]
That is, as shown in FIG. 5A, the main body attaching portion 12a is formed by forming a protrusion 12e at the L-shaped tip, and is inverted L-shaped and attached to the back surface of the main body case 11 by screws or the like. Further, two long holes 12f for engagement formed in a C-shape are provided in the L-shaped bent portion.
[0044]
The hook portion 12b is formed by forming a notch 12g at the tip of an L-shaped plate so as to be fitted to the protrusion 12e of the main body attachment portion 12a. The hook portion 12b has an inverted L shape and protrudes from the main body attachment portion 12a. It is designed to match. Two long holes 12f for engagement are also provided in a C-shape in the L-shaped bent portion of the hook portion, and when it is abutted as shown in FIG. It is adapted to face the engaging long hole 12f.
[0045]
As shown in FIG. 5B, the connecting plate 12c is a pair of plate-like members, and each connecting plate 12c has a part of a symmetrical side cut obliquely. Each connection plate 12c is provided with two protrusions (bosses) b in a line, and the distance between the two protrusions b is determined by the two members when the main body mounting portion 12a and the hook portion 12b are brought into contact with each other. The interval between the long holes 12f for engaging 12a and 12b is the same.
[0046]
The stopper piece 12d has a trapezoidal shape, and its size is a connection formed when two connecting plates 12c are attached to the main body attaching portion 12a and the hook portion 12b as shown in FIG. 5 (b). The size fits into the cut portion of the plate 12c.
[0047]
Therefore, the main body attaching portion 12a and the hook portion 12b are abutted at the upper portion of the door, and the two plates 12a and 12b are fitted with the projections b of the connecting plates (left and right) 12c fitted into the long holes 12f. If the stopper piece 12d is attached to the cut portion of the connecting plate 12c formed by the plate 12c with, for example, a double-sided tape, the connecting plate 12c can be moved, so that it can be attached without using screws.
[0048]
At this time, if the position of the long hole 12f into which the projection b of the connecting plate 12c is fitted is changed between “a” to “b” as shown in FIG. 5A, for example, the connection between the main body attachment portion 12a and the hook portion 12b. Since the interval can be changed, it is possible to cope with thick doors (moving from “I” to “B” as the door thickness increases). For example, when the thickness of the door is 30 mm, the protrusion of the connecting plate may be fitted at the position “A”, and when the thickness is 40 mm, the hook opening can be widened by fitting at the position “B”. By providing such an adjuster mechanism, the hook opening can be freely adjusted according to the thickness of the door.
[0049]
The hook portion 12b is provided with an emergency unlocking receptacle connector 40 as shown in FIG. As shown in FIG. 6, the receptacle connector 40 is provided on a display panel 43 that indicates a locked / unlocked state of a lock provided on the hook portion 12 b. The display panel 43 is provided with monitor lamps (LEDs) 41 and 42 for unlocking and locking in a horizontal row, and a receptacle connector 40 is provided in the middle of the monitor lamps 41 and 42. The connector 40 and the monitor lamps 41 and 42 are usually covered with a transparent plastic plate cover, and the connector 40 is used by breaking the cover. Incidentally, the monitor lamps 41 and 42 are red (unlocked) and yellow (locked).
[0050]
The connector 40 and the monitor lamps 41 and 42 are connected to the main body 1 with a cable. Here, a flat cable is used for this cable, which is introduced into the main body case through the back side of the locking portion 12.
[0051]
The receptacle connector 40 is of a jack type having a switch function for switching circuits, and is connected between the amplification circuit and the waveform shaping circuit of the main body sub-board SB as shown in FIG. As shown in FIG. 7, the radio reception means 38 of the sub board SB is composed of a tuning detection circuit, an amplification circuit, and a waveform shaping circuit. The tuning detection circuit detects a transmission signal from the radio remote controller 50, and By amplifying the detection signal by the amplifier circuit and inputting it to the waveform shaping circuit, an ID code signal (pulse train signal) as will be described later is input to the main board MB.
[0052]
Therefore, as described later, when the plug 51 of the wireless remote controller 50 is inserted into the jack 40, the connection between the amplifier circuit and the waveform shaping circuit is switched, and the waveform shaping circuit and the plug 51 are connected.
[0053]
In addition, the locking portion 12 of the main body 10 is provided with a slip stopper 12h (see FIGS. 9B and 9C). In this embodiment, the slip stopper 12h uses a double-sided tape (which does not leave an adhesive mark), and is attached to the "U" shape with the openings facing upward on the back surfaces of the main body attaching portion 12a and the hook portion 12b. By providing the slip stopper 12h between the door and the door 10 in this way, the main body 10 hung on the door is prevented from sliding left and right by a shock such as opening and closing of the door, or jumping upward and falling off.
In this embodiment, a double-sided tape is used for the slip stopper 12h, but the present invention is not limited to this. In addition to this, a rubber plate, a resin sheet with a large friction, or a protrusion or a rough surface formed directly on the locking portion 12 may be used. Further, since these slip stoppers 12h may be provided between the doors, they may be provided on the door side.
[0054]
On the other hand, as shown in FIG. 8, the wireless remote controller 50 includes a retractable plug 51, and includes a wireless transmission means 52, a microcomputer 53, an unlocking / locking switch means 54, and a pulse output means 55. ing.
[0055]
The wireless transmission means 52 is composed of, for example, an amplitude modulation circuit using a transistor, and an ID code output is output as a modulation signal from the microcomputer 53 to the transistor of the amplitude modulation circuit.
[0056]
The unlocking / locking switch means 54 is a switch circuit for locking and unlocking composed of switches and resistors. By pressing the unlocking / locking switch 54 connected to the microcomputer 53 as shown in the figure, The computer 53 outputs an unlock signal and a lock signal.
[0057]
At this time, the switch circuit 54 is connected to the base circuit of the transistor Tr1 connected in series between the battery B and the circuit as shown in the figure, and only when one of the switches 54 is pressed, the transistor Tr1 is connected. Operates and supplies power to other circuits.
[0058]
Further, an IC 56 for holding power is provided in parallel with the switch circuit 54. The IC 56 is connected to the microcomputer 53 and turns off the switching transistor Tr1 by a stop signal output from the microcomputer 53 after transmission is completed. It is like that. By doing so, power is supplied only when the remote controller 50 is operated, so that wasteful consumption of the battery B is suppressed, and long-term use is possible.
[0059]
The microcomputer 53 has a built-in ROM and is programmed to store the ID code in this memory. Although not shown, when the ID code is loaded from the code input terminal, it can be set in the built-in ROM memory.
[0060]
On the other hand, the plug 51 is a two-pole single-head type in this embodiment, and is connected to the microcomputer 53 in parallel with the wireless transmission means 52 via the pulse output means 55 provided as a buffer as shown in FIG. Thus, the ID code from the microcomputer 53 can be output directly (without passing through radio waves). The plug 51 is connected to a knob provided on the side surface of the case, and can be stored in the case or extended from the case by sliding the knob.
[0061]
This configuration is configured as described above, and this remote-control type lock is attached to the upper part of the door with the lock body 10 on the indoor side of the door.
[0062]
That is, as shown in FIG. 9A, the main body attaching portion 12a and the hook portion 12b of the main body locking portion 12 are fitted to the upper portion of the door, and the projecting portion 12e and the notch 12g of the main body attaching portion 12a and the hook portion 12b are provided. Match. At that time, as shown in FIGS. 9B and 9C, the main body attaching portion 12a and the hook portion 12b are fixed to the door with a slip stopper 12h. Then, the projections b of the connecting plates (left and right) are fitted into the long holes 12f of both the members 12a and 12b, and the two connecting plates 12c are attached. Further, the stopper piece 12d is attached to the cut portion of the two connecting plates 12c attached in this way with a double-sided tape or the like as shown in FIG. 9 (d). Then, the connecting plate 12c can be fixed without moving.
[0063]
At this time, when the door is thick, the main body attaching portion 12a and the hook portion 12b are spaced apart and fitted to the upper portion of the door. And the connection board 12c is attached to the long hole 12f of both the members 12a and 12b. At this time, since the long holes 12f are provided in a “C” shape, the long holes 12f are fitted in places where the distance between the long holes 12f and the distance between the projections b of the connecting plate 12c coincide. After that, if the stopper piece 12d is fitted to the back of the cut portion (because it can be fitted to the back by forming the trapezoidal shape), the connecting plate 12c can be prevented from moving. Therefore, if the connecting plate 12c is attached and fixed with a double-sided tape, the attachment is completed.
[0064]
Since such an adjuster mechanism is provided, it can be easily attached to doors of different thicknesses. At that time, since the fixing method using the stopper piece 12d is adopted, it can be easily attached without using a screw, so that it can be used with peace of mind in rental housing.
[0065]
On the other hand, when the main body 10 can be attached to the inside of the door in this way, as shown in FIG. 10, the receiving seat 60 is attached to the door collar corresponding to the bolt 14 of the remote control lock main body 10. Here, it has been described that the receiving seat 60 is attached to the door of the main body 10, but the present invention is not limited to this, and the receiving seat 60 may be attached first.
At this time, the ID codes of the remote control lock body 10 and the attached remote control 50 are the same, and the remote control 50 can only be operated.
[0066]
In the lock body 10 attached to the door in this manner, the power supply means 35 supplies power only to the wireless reception means at a predetermined interval, while the microcomputer 30 operates only the built-in timer and performs all remaining circuits. In the hold state, a signal from the wireless remote controller 50 is awaited and received.
[0067]
In this state, when the locking switch 54 of the wireless remote controller 50 is pressed, the microcomputer 53 of the wireless remote controller 50 detects it and transmits an ID code.
[0068]
In this form, for example, as shown in FIG. 11, this ID code is composed of a 7-digit code signal with 4 bits as one digit, and an ID for identification up to the sixth digit consisting of all 7 digits. As a signal, a mode signal such as opening / closing is output at the seventh digit. Further, by providing a 10-bit synchronization signal before and after the 7-digit code signal, the time of “1” of the 10-bit synchronization signal is measured, and then the time per bit is calculated. Even if the pulse width varies with temperature or voltage, the signal can be searched.
[0069]
Therefore, the main body 10 that has received the ID code detects the position of the bolt 14 with the sensor switch 16, and when detecting that the bolt 14 is in the open state, the actuator 15 is activated by the drive circuit 31 and locked from the sensor switch 16. The bolt 14 is moved until a condition is detected. At this time, the yellow LED 41 indicating the locked state is lit on the display panel 43 indicating the unlocked / locked state of the hook portion 12b.
[0070]
On the other hand, when the unlocking switch 54 of the wireless remote controller 50 is pressed, the bolt 14 is moved until the unlocking state is detected by the sensor switch 16. At this time, the red LED 42 indicating the unlocked state is lit on the display panel 43.
[0071]
Thus, since the unlocking / locking operation is performed by the wireless remote controller 50, a keyhole is not required. Therefore, it cannot be unlocked using a tool from the outside, and it can counter picking. Moreover, since it can be opened and closed with one touch, it does not take time to lock and unlock.
[0072]
Further, when a pressure is applied to the bolt 14 so as to forcefully open the door with a bar or the like, the switch 23 of the pressure detecting means 17 is activated to sound the buzzer of the alarm means 18, so that an alarm can be issued to the surroundings. Moreover, even if it tries to remove it by lifting it, it will not come in contact with the kite, so it is possible to make an attempt to enter.
[0073]
By the way, since the main body and the remote controller are wirelessly connected, it becomes impossible to unlock when the wireless state is poor or when the transmission means of the remote controller 50 is malfunctioning. In such an emergency, the cover of the transparent plastic plate of the display panel 43 is broken to expose the connector 40. Next, the plug 51 housed in the remote controller 50 is taken out, the plug 51 is inserted into the exposed connector 40 as shown in FIG. 12, and the unlocking switch 54 is pushed. Then, since the ID signal is transmitted to the circuit in the main body via the plug 51, it can be unlocked. Therefore, even in the case of wireless trouble, it can be unlocked without breaking the door, thus eliminating the weaknesses of the wireless remote control.
[0074]
【The invention's effect】
According to the present invention configured as described above, it is possible to cope with an unlocking action using a bar or the like, thereby improving the crime prevention performance and solving a trouble using radio. In addition, it can be easily attached to the door with a single touch, and its attachment strength is high.
