Definitions

• the present invention relates to an electronic lock device, comprising a motor lock and an electronic circuit, adapted to be mounted on an existing mechanical lock and to lock or unlock the mechanical lock in response to a signal from a signal device
• An alternative is to simply share one key. As long as all visits can be scheduled 100% this is a possibility, but in practice there are a lot of emergency calls (an elderly or disabled person needing immediate aid) or trading shifts etc. This means that the caregivers must meet up and exchange keys and each shift must return to the head office to return the keys so they can be used by the next shift. This is very ineffective, yet is actually the solution that is used in many places.
• a third alternative is to use a so called A-key, meaning that a master key is made that may gain access to all the homes of the people needing care. This is an efficient solution, yet has two major drawbacks; if a key is lost all locks of all homes must be changed.
• the traditional access control systems rely on wired data communication to update who has access where and when, which is not practical when dealing with many geographically distributed locations. Furthermore the traditional access control systems replace the existing locking system of the location. Generally this is done with a magnetic lock, which has the disadvantage of greatly lowering the security rating of the door. If security is an important factor, then often the door itself is replaced with one specifically designed for the access control system. This requires a lot of changes to the location where the access control system is to be installed; installing the data communication cables, changing or replacing the door.
• This key must be an electronic key, which is for more expensive than a purely mechanical key, and runs on battery.
• the unlocking device may e.g. be a Smartphone with a GPRS connection to a server.
• the unlocking device communicates with the electronic lock using some form of RF, e.g. Bluetooth.

• the present invention relates to an electronic lock device, comprising a motor lock and an electronic circuit, adapted to be mounted on an existing mechanical lock and to lock or unlock the mechanical lock in response to a signal from an unlocking device, wherein the electronic lock device comprises a coupling adapted to ensure that the mechanical lock can be operated manually at all times, wherein the coupling is a disc coupling.
• the electronic lock device provides safety for the users as the door can be opened at all times, even at failure of power, e.g. due to fire or other events.
• the electronic lock device is adapted to be mounted on only one side of a door. The electronic lock device will only be visible on the side of the door on which it is mounted and not visible on the other side of the door. Thus, the electronic lock may be invisible from the outside and yet allow the use of e.g. an FID tag for unlocking and locking the door (using the RFID reader through the door "plate")
• the electronic lock may be combined with other electronic lock devices and operated as a traditional access control system.
• the individual locations may receive updates regarding who may obtain access and when in realtime and where the location can transmit events back to the central server in real-time using wired data communication, or the GSM network to create a virtual wired network.
• the electronic lock is installed, operated for a period on a door and removed without leaving any visible marks on the door.
• the electronic lock device is adapted to be mounted on a door without permanent mounting means, such as nails or screws, but e.g. with a special designed metal attachment or double adhesive tape. The electronic lock device can then be dismounted without requiring plaster or paint to restore the door.
• the electronic lock device may support other control or sensor devices via the electronic circuits RF communication line (Bluetooth or ISM) and transmit it to the electronic lock server to gain a more complete view of the locations status.
• the electronic lock device is adapted for parallel manual operation of the mechanical lock. Consequently, in this embodiment the mechanical lock can be operated manually on a daily use basis without causing any damage to the electronic lock device.
• the embodiment allows for parallel operation of the existing mechanical lock, i.e. the existing lock may be used without any change in procedure both from the inside and the outside, while the online electronic lock may be used in parallel to unlock or lock the same mechanical lock.
• the unlocking device or device for unlocking the electronic lock device is selected from the group comprising RFID, NFC (Near-Field Communication), keypads, smart phones, phone-call, DTMF, and SMS.

• the electronic lock device according to the invention may be adapted to lock or unlock an electronic lock, automatic door, gate or boom, and the invention provides lock solutions for numerous applications.
• the invention also comprises an embodiment wherein the electronic lock device is integrated with an automatic door opener, a smoke alarm, a fire alarm, or a panic button.
• This embodiment is highly useful, e.g. in the homes of elderly people, in schools or other public buildings.

• the major problem with this is the requirements to the unlocking device. It needs to maintain two data channels (GPRS and Bluetooth), and cache and transmit events back to the server. This drains the batteries relatively fast, causing entry to be prohibited.
• the unlocking device itself (the Smartphone) is also much more expensive than a purely mechanical key or even an electronic key (e.g. Ruko CLIQ), and require some level of technical understanding to operate.
• Having the unlocking device contain the data channel to the server furthermore prevents the system to send events while the unlocking device is out of reach, and any errors that may occur (or other occurrences of interests, like battery low) cannot be sent to the server until the someone is standing in front of the door with an unlocking device, and if the occurrence is battery low, then this can be a big problem.
• the existing lock devices also suffer from a safety aspect. As they are designed to operate in parallel with the existing solution they must allow for the door to be operated by means of a mechanical key (from the outside) and thumb-turn (from the inside). This is attempted solved by enabling or disabling the electronic lock, so that it is only engaged when needed.
• the present invention solves these aforementioned problems by moving the authentication functionality to the electronic lock and making it online by the use of a GSM modem. This allows for the unlocking device to be greatly simplified and may e.g. be an RFID tag, a
• Bluetooth signal (with no need for a GPRS connection), a simple matrix keypad (wired or wireless), etc. This allows the system to be used by someone without a Smartphone with a special application installed.
• the online electronic lock Since the online electronic lock is mounted inside the residence or area, it is possible to improve GSM reception by simply attaching a better GSM antenna or using a GSM antenna relaying station if needed.
• the online ability also ensures that any events that occur (access granted, unauthorized access attempted, error, etc) may be transmitted instantly, just like the online electronic lock may obtain updated access permissions (who may enter where and when) instantly, meaning that a lost unlocking device may be cancelled immediately, and no "timeout" of the access permission is required.
• Another difference in the online electronic lock is that since it is online it is possible to remotely control the door, which means that if someone have forgotten their key, or a doctor or other emergency personnel need access to a patients home, it is possible to remotely unlock the door. This principle is well known from high end cars in the USA, where a central service can unlock the doors and override the car ignition.
• a disc coupling is characterised by being able to glide if too much force is applied. This means that if the mechanical lock is operated manually at the same time as the online electronic lock is operating the motor lock then the discs of the disc coupling will simply glide against each other and the lock may be operated manually both from the inside or the outside. As the disc coupling is electromagnetic and engaged when power is applied then the system will instantly disengage in case of a power failure, no matter when it occurs, and there is no way the motor may be left in an engaged state no matter how unfortunate the timing of the power failure may be. This is naturally of little importance, as the disc coupling may always be forced, yet it is an extra safety feature. In order to support unchanged manual operations of the mechanical lock it is imperative that the motor lock operates easily enough to allow the existing spring in a close lock (Dk:
• the online electronic lock also support extensions with other functionality like a smoke detector, emergency call system, heart monitor, etc.
• the GSM modem allows for remote update of the firmware, thereby allowing modifications to the running code without gaining access to the physical unit. This is not possible if it is the unlocking device that has the data communication channel.
• the integration with a fire and smoke detector also allows for automatically unlocking the door in case of a fire. This will allow not only emergency personnel, but also a helpful neighbour or passer-by, to enter and aid anyone inside, which might be an elderly or disabled person.
• the online electronic lock may be used in a configuration where the motor lock is not installed at all and the electronic circuit instead controls a magnet lock, an automatic door opener, a gate or boom, etc.
• This has the advantage that the same unlocking device may be used regardless of whether the location to access is already fitted with an electronic lock, as the electronic circuit may simply control the existing electronic lock.
• the online electronic lock consists of a motor lock and an electronic circuit.
• the motor lock may be seen in figure 3 and in Table 1 is given a description of the individual parts of the motor lock.

• the thumb turn adapter may be replaced to fit different mechanical lock types.
• the shown thumb turn adapter is used with a Thumb turn extender (used with ASSA Rim & mortice locks - DK: Indskukken lasekasse).
• the electromagnetic coils of the disc coupling used to generate the magnetic field which draws the front disc coupling plate (7) to the back disc coupling plate (11).
• the force of this magnetic field along with the surface of the coupling discs determine the torque required before the discs will glide against each other.
• the base of the housing This is responsible for holding the inner components, which includes any force exerted by the inner components which is not directed at the mechanical lock (undesirable force leak) - some degree of force leak is unavoidable and manifests as friction.
• the motor holder This is responsible for affixing the motor to the base of the housing (22) and ensure that the motor shaft and disc coupling is correctly aligned with the front part of the disc coupling, pinion wheel shaft and pinion wheel.
• a diagram of the electronic circuit may be seen in figure 4, and the individual parts of the circuit are labelled on the figure.
• the indicated RJ45 is the connection between the motor lock and the electronic circuit, and contains wiring for the power to the disc coupling (labelled “clutch”) and the power to the motor, as well as power and communication to an optional RFID reader, as may be seen mounted in figure 5.
• the mounting of the online electronic lock consists of installing the motor lock on the door's mechanical lock, drawing the wire across the door inside a metal brace and plugging in the electronic circuit.
• figure 5 may be seen an actual installation of the invention.
• the electronic circuit is in a separate housing than the motor lock, yet this is not a requirement.
• the motor lock and electronic circuit is in the same housing it is merely the power supply for the electronic circuit that is drawn across the door in the metal brace.
• Table 2 - Components of the online electronic lock The installation of the online electronic lock is performed as shown in figure 6. Here it may be seen that a steel attachment is used to attach the online electronic lock to the door. This attachment is designed, as previously mentioned, to leave no visible marks on the door, so that the online electronic lock may be taken down without leaving marks on the door.
• Figure 6 shows the installation of the online electronic lock.
• lock types and though it is not possible to adapter which may support them all, it is possible with a relatively small assortment of attachments to support the most common types, and as new types are discovered the attachments may simply be modified or a new attachment developed to support the new lock type.
• the thumb turn adapter is used to adapt the motor lock to the given mechanical lock type.
• Several mechanical locks make use of a small flat piece of iron to connect the mechanical lock to the thumb turn adapter, and this is therefore the most common thumb turn adapter type.
• An alternative is where the existing thumb turn adapter may not be removed, and here a different thumb turn adapter is used. Both of these examples are shown in figure 7.
