DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cylinder lock which is attached to a door of a house or a vehicle, for example, a front door, and locks the door. In particular, the invention relates to a cylinder lock capable of preventing damage due to picking and a notification using the cylinder lock. apparatus,
The present invention relates to an alarm device and an output device.

[0002]

2. Description of the Related Art In order to prevent damage such as theft, a cylinder lock is attached to a door of an apartment or a safe, for example. The cylinder lock has a structure in which the rotation of the inner cylinder is restricted by a plurality of upper pins and lower pins, and the shape of the key is determined by the combination of the lengths of the lower pins. There is an advantage that it can be manufactured.

[0003] However, recently, theft damage due to picking has been reported on televisions and newspapers. Picking is a process in which the lower pin is pushed up by a special tool while applying tension to the inner cylinder in the unlocking direction, and the boundary between the upper pin and the lower pin is changed to the boundary between the inner cylinder and the outer cylinder (this is generally referred to as a shear line).
ar line). ), And by sequentially performing this for each lower pin, the act of rotating the inner cylinder and unlocking it. Whether or not the boundary between the upper pin and the lower pin comes to the boundary between the inner cylinder and the outer cylinder is determined by the feel of the finger when the outer peripheral surface of the lower pin touches the outer cylinder.

[0004] There is a pin cylinder lock using an anti-picking pin which is currently on the market in order to prevent picking damage. 9A and 9B are views for explaining an example of the anti-picking pin. FIG. 9A is a cross-sectional view of a main part of the cylinder lock in a locked state, FIG. 9B is a cross-sectional view of a picked state, FIG. (C) is a perspective view of the upper pin.
In the drawing, 1 is an outer cylinder, 1a is a cutout, 2 is an inner cylinder, 2a is a keyhole, 3 is an anti-picking pin, 3a is a flange, 4 is a lower pin, and 5 is a spring.

[0005] This cylinder lock is characterized by the shape of the upper pin, and the anti-picking pin 3 is used as the upper pin. As shown in FIG. 9C, the anti-picking pin 3 has a mushroom shape having a flange 3a formed at the tip. In the locked state shown in FIG. 9A, the anti-picking pin 3, which is the upper pin, penetrates to the inner cylinder 2 in the same manner as a normal cylinder lock.
Is prevented from rotating. When the lower pin 4 is pushed up while applying power to the inner cylinder 2 in this locked state, FIG.
As shown in (B), the flange of the anti-picking pin 3 is caught by the notch 1 a provided at the boundary of the outer cylinder 1. If the rotation force applied to the inner cylinder 2 is loosened to remove it, the other upper pin that has already been pushed up falls.

FIG. 10 is a view for explaining an example of a cylinder lock using the above-described anti-picking pin.
FIG. 10A is an axial sectional view of the locked state, and FIG.
10B is a top view, FIG. 10C is a front view, and FIG.
Is a sectional view in the axial direction with a key inserted. In the figure,
Parts similar to those in FIG. 9 are denoted by the same reference numerals, and description thereof is omitted. 6 is an upper pin, 7 is a click ball, 7a is a spring, 8 is a key, 9 is a pinhole cover, and 10 is a shear line.

In this example, the anti-picking pins 3 are used as four upper pins out of six pins. As the other two sets, that is, the uppermost pin 6 at the forefront and the rearmost part, an ordinary columnar pin is used. As shown in FIG. 10A, in the locked state where the key is not inserted, the anti-picking pin 3 and the upper pin 6 penetrate the inner cylinder 2 and
Is prevented from rotating. FIG. 10D with key 8 inserted
In the condition (1), the boundary between the anti-picking pin 3 and the lower pin 4 below the anti-picking pin 3 and the boundary between the upper pin 6 and the lower pin 4 coincide with the shear line, and the inner cylinder 2 can be rotated.

[0008] By providing a large number of such anti-picking pins, picking becomes difficult. However, it is hard to say that the picking technique will be improved if the picking technique is improved. Further, since the picking is performed by the above-described method and almost no trace remains, there is a problem that it is often unclear whether or not the lock has been opened by the picking.

[0009]

FIG. 1 is a view for explaining a first embodiment of a cylinder lock according to the present invention.
FIG. 1B is an axial sectional view in a state where a normal key is inserted, FIG. 1C is an axial sectional view in a state where picking is performed, FIG.
FIG. 1D is a side view of the sensing pin and the lower pin, and FIG. 1E is a sectional view of the sensing pin and the lower pin. In the figure, the same parts as those in FIGS. 9 and 10 are denoted by the same reference numerals. 11 is a sensing pin, 11
a is a sensing portion, 11b is a cylinder portion, 11c is a spring accommodating groove portion, 12 is a lower pin, 12a is a reduced diameter portion, 13 is a sensing switch, 14 is a sensing switch holding plate, 15 is a tape wire,
Reference numeral 16 denotes a special tool.

In this embodiment, for the upper pin,
A normal cylindrical upper pin 6 is used at the forefront, four anti-picking pins 3 described with reference to FIGS. 9 and 10 are used, and a sensing pin 11 is used at the last. Therefore, six sets of upper pins and lower pins are provided. However, the combination, the number of sets, and the position may be arbitrary. Of course, the total number of sets is not limited to six as in this embodiment. Alternatively, the anti-picking pin 3 may be replaced with a normal cylindrical upper pin 6 without using the same. Also, as described in the second embodiment,
The number of sets using the sensing pins is not limited to one, and a plurality of sets may be used.

The sensing pin 11 activates the sensing switch at the rear portion, and is selected to have a predetermined length for actuating the sensing switch 13 when the sensing pin 11 moves a predetermined distance from the locked position. FIGS. 1D and 1E show an example of the structure.
Will be described. In this example, the sensing pin 11 is composed of two members. The tip of the sensing unit 11a is the lower pin 1
2, and the rear end is the predetermined length described above to activate the sensing switch. The sensing unit 11a is a cylinder unit 1
1b. The cylindrical portion 11b is formed with a spring accommodation groove 11c that can accommodate the tip of the spring 5 at the upper part. However, the spring accommodating groove 11c is not always necessary, and without the spring accommodating groove 11c, as shown in FIG. 10, the upper end surface of the cylindrical portion 11b is made flat, and the sensing portion 11a is projected to the center. In this way, the tip of the spring 5 may be abutted. The length of the upper end of the sensing portion 11a protruding from the upper end surface of the cylindrical portion 11b is selected, and when the upper end surface of the cylindrical portion 11b abuts on the pinhole cover 9 by picking, the sensing portion 11a Is the sensing switch 1
If the value of d (FIG. 1D) is selected so as not to exceed the limit of the operating stroke, the advantage that the sensing switch having the operating limit is not damaged can be provided. Can be. Sensing part 11a and cylinder part 1
As for 1b, these may be formed integrally, but if they are formed separately, only by replacing the sensing part,
The picking sensing position can be selected. Also,
The forming process of the spring accommodating groove 11c is easy.

In this embodiment, both ends of the anti-picking pin 3 and the upper pin 6 have the ends of the spring 5 on the side facing the spring 5 so as to provide the same action as the spring accommodating groove of the cylindrical portion 11b. A hole that can be inserted is provided. However, as with the sensing pin 11, a flat surface may be used without providing a hole on the end surface facing the spring 5. .

As for the lower pin, as for the set of the anti-picking pin 3 and the upper pin 6, a normal cylindrical lower pin 4 having the same outer diameter up to the upper surface is used.
The lower pin 12 having the upper portion reduced in diameter to form a step was used as the lower pin to be combined. As shown in FIGS. 1D and 1E, a reduced diameter portion 12a having a smaller outer diameter is formed on the side of the lower pin 12 which is in contact with the sensing pin 11. Since the reduced diameter portion is formed on the lower pin 12, the tactile sensation at the time of picking is delayed, so that the possibility of lifting the lower pin until the sensing switch is pressed increases the possibility of operating the sensing switch 13. Is increasing. Also,
Since the upper portion of the lower pin has a stepped shape, it also has an action as an anti-picking pin. Therefore, lower pin 4
Instead, a lower pin 12 having a reduced diameter portion may be used.

The click ball 7 is pressed by a spring 7a and is engaged with a hole formed in the inner cylinder 2. When the rotating power is loosened during the picking while the rotating power is applied to the inner cylinder 2, the inner cylinder 2 has a role of returning the inner cylinder 2 to a normal state (the original state), thereby making it difficult to perform the picking.

The sensing of picking will be described. FIG.
In the normal locked state shown in FIG.
Is not in the position to activate the sensing switch 13. When the normal key 8 is inserted, as shown in FIG. 1 (B), the lower pin of each set is pushed up by the key 8, the upper pins are moved in the same manner, and the upper and lower pins of all the sets are moved. Is aligned with the shear line 10, and the inner cylinder 2 can be rotated.
Depending on the normal insertion of the key 8, the position of the sensing pin 11 is the position of the shear line 10, and the sensing pin 11 does not operate the sensing switch 13 at a moving distance to this position.

When picking is performed, as shown in FIG. 1C, the sensing pin 11 may be moved further upward beyond the shear line 10. By this movement, the upper portion of the sensing pin 11 passes through the hole formed in the pinhole cover 9 to activate the sensing switch 13, so that the sensing switch 13 can generate a sensing signal. In using the cylinder lock, usually only the normal key 8 is inserted. Therefore, it can be said that actuation of the sensing switch 13 is abnormal, and this signal can be used to detect an abnormality such as picking.

FIGS. 2A and 2B are views for explaining an example of mounting of the sensing switch. FIG. 2A is a top view and FIG. 2B is a side view. In the figure, the same parts as those in FIG. Reference numeral 15 denotes a tape electric wire. In this example, a tape wire 15 is connected to the sensing switch 13, and the sensing switch 13 is attached to the outer cylinder 1. A stepped groove is engraved at an appropriate position in the outer cylinder 1 so that the sensing switch can be accommodated. A pinhole cover 9 is inserted into the stepped groove, and the operation of the sensing switch 13 is inserted into a switch hole provided in the pinhole cover 9. The sensing switch 13 is fixed by dropping a part and inserting a sensing switch holding plate 14 above the part.

FIG. 3 is an axial sectional view of a locked state for explaining a second embodiment of the cylinder lock according to the present invention. In the figure, the same parts as those in FIG. 17 is a spacer.

In this embodiment, two sets using the sensing pins 11 are provided. Therefore, the sensing switches 13 are also provided at two locations corresponding to the sensing pins 11. In this embodiment, since the sensing switch holding plate 14 is commonly used for the two sensing switches 13, the spacer 17 is inserted to fill the step of the tape wire 10. In this case, the sensing switch signal may be serial data or parallel data.

In the above-described embodiment, the structure in which the pair of the upper pin and the lower pin is located on the upper surface of the inner cylinder 2 is provided. The pair of the upper pin and the lower pin is located on the side surface of the inner cylinder 2. You may do so. Further, it may be located on both the side surface and the upper surface. The location where the set of the upper pin and the lower pin is located may be anywhere on the inner cylinder peripheral surface.

FIG. 4 is an axial sectional view of a locked state for explaining a third embodiment of the cylinder lock according to the present invention. In the figure, the same parts as those in FIGS. 1 and 3 are denoted by the same reference numerals, and description thereof will be omitted. 18 is an operation member.

In the first and second embodiments, the sensing switch 13 is directly operated at the rear end of the sensing pin 11 to sense the movement of the sensing pin 11 over a predetermined distance. In the embodiment, the operating member 18 is brought into contact with the rear end of the sensing pin 11, the operating member 18 is moved by the movement of the sensing pin 11, and the sensing switch 13 is operated by the movement of the sensing pin 11 by a predetermined distance or more. I tried to make it. Although two sets using the sensing pins 11 are provided,
One set may be used, or three or more sets may be used. In addition, although a normal cylindrical pin is used as the sensing pin 11, an anti-picking pin may be used. In short, it is only necessary that the operating member 18 can be moved. The lower pin facing the sensing pin 11 does not have the reduced diameter portion described above, but uses a lower pin 4 having a columnar upper portion. However, the reduced diameter portion described with reference to FIGS. The formed lower pin 12 may be used.

The operating member 18 is moved by gravity to the sensing pin 11.
When the cylinder that accommodates the upper pin is formed in the outer cylinder 1 in the direction in which it is placed on the rear end, the operating member 18 is always placed on the rear end of the sensing pin 11 without any problem. In the case where is formed laterally or downward, it is preferable that a spring is also arranged on the actuating member 18 so as to bias it toward the rear end of the sensing pin.

Further, switch means is used as sensor means for detecting the movement of the sensing pin. The switch means is not limited to a switch having mechanical contacts such as a micro switch, and it goes without saying that a sensing switch means such as a proximity switch or a photoelectric switch can be used. The sensor means is not limited to the switch means. In short, the sensor means only needs to detect the movement of the sensing pin within a predetermined distance and obtain a signal output. In addition, the movement of a predetermined distance is used to include a movement exceeding a predetermined distance.

FIG. 5 is a block diagram for explaining an example of signal processing of a cylinder lock according to the present invention. In the figure, 13
Is a sensing switch, 15 is a tape wire, 20 is a transmitter, 2
1 is an input unit, 22 is a counter unit, 23 is a timer unit, 2
4 is a transmitting unit, 25 is a transmitting unit, 26 is a power supply, 27 is a power switch, 28 is a display unit, 30 is a receiver, 31 is a receiving unit,
32 is a signal generation unit, 33 is an output unit, 34 is a display unit, 35
Denotes a power supply unit.

In this example, it is assumed that the transmitter 20 is installed near the cylinder lock of the door on which the cylinder lock is installed, and that the receiver 30 is installed in a room near the door. However, the present invention is not necessarily limited to this, and an appropriate configuration such as integrating the transmitter 20 and the receiver 30 is possible.

The above-described sensing switch 13 is connected to the input unit 21 of the transmitter 20 via the tape wire 15.
When a switch using a mechanical contact such as a micro switch is used as the sensing switch 13, the sensing switch 13
From the side, only the contacts are connected to the tape wire 15, power is supplied to the input unit 21, and a sensing signal based on the ON / OFF of the switch is output from the input unit 21. When a proximity switch, a photoelectric switch, or the like is used as the sensing switch 13, the input unit 21
5, the power supply voltage is sent to the sensing switch 13 side, and the sensing signal is sent from the sensing switch 13 side to the input unit 21.

In this example, the output signal output from the input unit 21 is a signal which becomes 1 only while the sensing pin operates the sensing switch, and becomes 0 when the sensing switch is not operated. When a signal is input a predetermined number of times (for example, three times) within a predetermined time (for example, two seconds) from the first signal input, the counter unit 22 outputs a signal indicating an abnormality. It is generated and transmitted from the transmitting unit 25. The transmission is preferably a radio signal such as radio waves or infrared rays, and the transmission signal may be a one-shot signal or a continuous signal. For a continuous signal, turn the power switch 27
The output of the abnormal signal may be canceled by setting F. Further, an alarm buzzer or the like may be provided in the transmitter 20. The power source 26 of the transmitter 20 preferably uses a battery.
The display unit 28 notifies of a drop in the power supply voltage, and also displays a power-on state. It is preferable to use display by LED or LCD.

As described in the second embodiment, when two or more sensing switches are used, the signal from one sensing switch is input within a predetermined time and then the other sensing switch is used within a predetermined time. This makes it possible to perform more complicated control such as outputting an abnormal signal when no signal is input, which is advantageous in preventing malfunction. Further, the lower pin does not need to have a stepped shape, and can have the same shape as other lower pins.

The receiver 30 receives the signal from the transmitter 25 of the transmitter 20 at the receiver 31. The signal generation unit 32
Based on the received signal, a signal suitable for notification, alarm, and the like is generated and output from the output unit 33. The power supply unit 35 uses a commercial power supply in this example. The display unit 34 displays a power-on state. An alarm buzzer or the like may be provided in the receiver 30. In addition, it is possible to make a notification or an alarm based on an output signal from the receiver 30.

FIG. 6 is a schematic configuration diagram for explaining an example of a type in which a security buzzer sounds due to an abnormal signal.
6A is a cross-sectional view near the door, and FIG. In the figure, 40 is a cylinder lock, 41 is a thumb turn, 42 is a lever handle, 43 is a door, and 44 is a control panel with a security buzzer.

The control panel 44 with a security buzzer is attached to the door 43 so as to straddle the board of the thumb turn 41 on the indoor side of the cylinder lock 40. If it is attached at the time of manufacturing the door 43, it is preferable to incorporate it into a part of the door 43. However, if it is attached later, it may be attached by a method such as bonding with a double-sided adhesive tape or the like. In the example using the tape wire described above, the cylinder lock 40 is connected to the control panel 44 with a security buzzer by a tape wire. As the control panel 44 with a security buzzer, the same one as the transmitter 20 described in FIG. 5 can be used, and a buzzer as a warning device built in the transmitter 20 can be sounded. Transmitter 24, transmitter 2 in transmitter 20
5 may be omitted. However, when the soundproofing performance of the door 43 is high, there is a problem that the sound cannot be heard outside. Therefore, the transmission unit 24 and the transmission unit 25 may use the transmission to the receiver together. Note that the alarm device is not limited to a buzzer, and another alarm device that emits sound, light, or the like may be used.

FIG. 7 shows a case where an abnormal signal is sent to an automatic reporting device,
7 (A) is a cross-sectional view near the door, FIG. 7 (B) is an installation view on the indoor side, and FIG. 7 (C) is a view on the receiving side. It is a schematic block diagram. In the figure, 20 is a transmitter, 30 is a receiver, 45 is an automatic notification device, 46 is a buzzer, and 47 is a mobile phone.

The door side is the same as that described with reference to FIG. 6, except that a transmitter 20 is attached to the door. As the transmitter 20 and the receiver 30, those described with reference to FIG. 5 are used. The output of the receiver 30 is sent to the automatic reporting device 45
Is input to The automatic notification device 45 can take in abnormal signals from, for example, eight locations, and when an abnormal signal is input, sounds a buzzer 46 as an alarm device, and inputs a mobile phone number that has been input in advance, for example, a security company. To a mobile phone number, and send a message notifying the abnormality by voice or mail. The call may be transmitted not only to the mobile phone but also to a commercial line or a dedicated line. Receiver 30
May be attached to the indoor side, and only the indoor alarm may be provided by switching between going out and staying at home. As described above, the alarm device is not limited to the buzzer.

FIG. 8 is a view for explaining an example of a type in which a chime is sounded by transmitting to the intercom master unit. FIG. 8 (A) is a cross-sectional view near the door, and FIG. FIG. 8C is a schematic configuration diagram on the receiving side. In the figure,
The same parts as those in FIG. 7 are denoted by the same reference numerals, and description thereof will be omitted. 48 is an intercom master unit, and 49 is a door phone slave unit.

The output of the receiver 30 is output to the intercom master 4
8 is input. The intercom master unit 48 sounds a pre-recorded sound from an external speaker of the intercom slave unit 49, sounds a chime sound, or sounds an entrance chime. Anyone trying to open the lock by picking will escape, noticed thereby. Other alarm devices may be activated.

[0048]

As is apparent from the above description, according to the present invention, it is possible to eliminate the problem that no trace is left and it is unclear whether picking has been performed. It is possible to interlock with a notification device or an alarm device by a sensing signal, and to provide a notification or a threat.
