Description

  The present invention relates to a cylinder lock having a specific function. The present invention also relates to an electric lock system using a cylinder lock having a specific function.

There are many families and businesses in apartment buildings and tenant buildings. In multiple dwelling houses and tenant buildings, the front door is a shared part of each household and each company.
The front door must be locked for crime prevention. On the other hand, in apartment houses and tenant buildings, it is desirable that each resident can freely lock and unlock the front entrance.
For this reason, in apartment houses and tenant buildings, for example, a card-type electric lock system as disclosed in Patent Document 1 may be introduced.
The card-type electric lock system is a combination of an electric lock and a card reader. The electric lock is a device that physically locks the entrance door, and is built in the entrance door or door frame.
The card reader reads card information and is attached to the entrance door or the vicinity of the entrance door.
In the card-type electric lock system, when the user exposes the card to the card reader, the electric lock is unlocked and the entrance door can be opened.

In recent years, there are apartment houses that introduce an electric lock system called a keyless system.
The keyless type electric lock system is a combination of an electric lock and a wireless receiver. In the keyless electric lock system, transmitters such as remote controllers that transmit weak radio waves are distributed to residents. When the user with the transmitter approaches the entrance, the receiver receives the radio wave transmitted by the transmitter, and makes the electric lock unlockable. When the user operates a predetermined switch or touches a predetermined place, the electric lock is unlocked and the entrance door can be opened.

FIG. 9 shows an example of an entrance door employing a conventional electric lock system.
In the electric lock system 100 of the prior art, there is a door frame 102 that holds a door 101, and a card reader 105 or the like is attached to the door frame. In the electric lock system 100 of the prior art, the card reader 105 and the like are members different from the door handle 106 and the key holes 103 and 104 into which the keys are inserted, and are physically separated from the key holes 103 and 104 and the like. A card reader 105 or the like was attached.

The push button switch 47 is a switch for unlocking the lock (the lock bodies 17a and 17b).

In the present embodiment, the decorative member 31 is mounted on the cylinder body 30 a, and the tip portion of the inner cylinder 35 of the cylinder body 30 a is exposed from the opening 43 of the lid member 40.
Further, there is a space between the cylinder body 30a and the lid member 40 of the decorative member 31, and the substrate 45 is built in the space. The push button switch 47 provided on the substrate 45 is in a position directly behind the movable piece 42 of the lid member 40, and the push button switch 47 is operated by pushing the movable piece 42.

  The substrate 45 has a signal line 49, and the signal line 49 passes through the decorative member 31 and is drawn out to the back side of the decorative member 31.

Next, the lock unit 7 with a card function will be described.
As shown in FIG. 6, the lock unit 7 with a card function also has a thumb turn 18b in the lock body 17b, and a cylinder lock 50 with a card function is provided in place of the cylinder lock 20 with a keyless function.
The lock body 17b is the same as the above-described lock body 17a, and detailed description thereof is omitted. The thumb turn 18b is also the same as the thumb turn 18a, and detailed description thereof is omitted.

As shown in FIGS. 7 and 8, the cylinder lock 50 with a card function has a cylinder body 30 b and a decorative member 51 like the cylinder lock 20 with a keyless function.
The cylinder body 30b of the cylinder lock 50 with a card function is the same as the cylinder body 30a of the cylinder lock 20 with a keyless function.

Since the decorative member 51 has substantially the same structure as that described above, the same reference numerals are assigned to the common members, and duplicate descriptions are omitted.
The lid member 52 employed in the decorative member 51 is a single circular member having an opening 43.

In the cylinder lock 50 with a card function of the present embodiment, an electronic device is incorporated in the decorative member 51. Specifically, a substrate 55 is built in the decorative member 51.
The substrate 55 is an electronic device having a function related to a condition for unlocking the lock unit 6 with a keyless function and the lock unit 7 with a card function.
The board 55 of the cylinder lock 50 with a card function has a card reader 56. The substrate 55 is provided with an IC 58 for ID analysis.
The card reader 56 communicates with a card 66 held by a resident and reads information written on the card 66. The ID analysis IC 58 analyzes the received signal and determines whether or not it is appropriate.

In the entrance door 1 of the present embodiment, a lock unit 6 with a keyless function is attached on top of a push-pull lock unit 5, and a lock unit 7 with a card function is attached thereunder.
The lock unit 6 with a keyless function and the lock unit 7 with a card function are connected to a control device (not shown).
The lock bodies 17a and 17b of the lock unit 6 with a keyless function and the lock unit 7 with a card function can be unlocked with a key. The lock bodies 17a and 17b of the lock unit 6 with a keyless function and the lock unit 7 with a card function can both be locked and unlocked by an electric signal.

That is, the front door 1 of the present embodiment can be brought into an unlockable state by three methods: a method of using a key, a method of carrying a transmitter (remote controller), and a method of holding a card.
That is, the lock bodies 17a and 17b of the lock unit 6 with a keyless function and the lock unit 7 with a card function can be unlocked by inserting a key (not shown) into the cylinder bodies 30a and 30b and turning the key. . The latch can be rotated by pushing or pulling the push-pull handle 11, and the door body 3 can be opened by pushing or pulling the push-pull handle 11.

In addition, a transmitter (remote controller) 65 and a card 66 are distributed to residents.
The transmitter 65 constantly transmits weak radio waves.
When the user approaches the entrance door 1 with the transmitter 65 in a pocket or a bag, the wireless receiver 46 of the substrate 45 disposed in the decorative member 31 of the lock unit 6 with the keyless function is moved from the transmitter 65. Receive outgoing radio waves. Then, the IC 48 for ID analysis analyzes the signal and determines whether or not it contains a signal that meets a predetermined condition.
If the received signal includes a signal that matches a predetermined condition, the information is transmitted to a control device (not shown), and an unlocking preparation state is set.
Then, when the user presses the movable piece 42 of the lid member 40 and the push button switch 47 is turned on, the lock unit 17a, 17b of the lock unit 6 with a keyless function and the lock unit 7 with a card function is brought from a control device not shown. An unlock signal is sent. Both the keyless function-equipped lock unit 6 and the card function-equipped lock unit 7 are both unlocked. The latch can be rotated by pushing or pulling the push-pull handle 11, and the door body 3 can be opened by pushing or pulling the push-pull handle 11.

The card 66 has a built-in chip for storing information. When the user takes out the card 66 from a pocket or the like and holds it over the decorative member 51 of the lock unit 7 with card function, the card reader 56 of the substrate 55 arranged in the decorative member 51 communicates with the IC chip of the card 66. Then, the IC 58 for ID analysis analyzes the signal and determines whether or not it contains a signal that meets a predetermined condition.
If the received signal includes a signal that matches a predetermined condition, the information is transmitted to a control device (not shown). Furthermore, an unlocking signal is transmitted from the control device to the lock bodies 17a and 17b of the lock unit 6 with a keyless function and the lock unit 7 with a card function. And the lock unit 6 with a keyless function and the lock unit 7 with a card function will be in an unlocked state. The latch can be rotated by pushing or pulling the push-pull handle 11, and the door body 3 can be opened by pushing or pulling the push-pull handle 11.
