2. Description of related Art

Many access control panels currently available have the option of continuously monitoring the load resistance of their inputs/outputs to the access point, for example, whether the door lock control is open or closed. The system is intended to allow the access control panel to identify whether an access point has been tampered with, when switched on or off with a resistance value set in the system. Monitoring the resistive load is typically implemented on the load panel. However, the wire operation is typically not monitored between the load panel and the door position switch, and the current location of the resistor network, i.e., close to the access panel, makes the line susceptible to tampering or cutting the line or shorting the circuit.

Detailed Description

In describing embodiments of the present invention, reference will be made herein to the accompanying drawings in which like numerals represent like features of the invention. The present invention is directed to an electronic door lock system in which the electronic components within the lock are electronically connected to an external unit, such as an access control panel, located outside the lock. Such electronic components may be sensors located inside the door lock body, and may be contact switches, magnetically operated reed switches, hall effect sensors, and/or other types of sensors. Such sensors may be positioned to signal the position of the mechanical assembly within the lock and/or door. The sensor may be used to indicate whether the door lock is in a locked or unlocked state. Which may indicate whether the latch bolt is extended or retracted or whether the door to which the lock is mounted is opened or closed. It may monitor the position of the deadbolt, rotation of the handle, or signal whether the lock has performed other functions. The connection from the lock to the access control panel is typically through wires from the wiring harness to the access control panel.

The electronic door lock system may be configured to monitor load resistance according to a customized and installed resistive network circuit configuration by allowing an external device to allow tamper detection, such as an access control panel, which is typically installed in a wire near the access control panel. The configuration of the resistor network circuit will indicate the status of the device, e.g., whether the door lock control is open or closed, based on the set resistance value.

The access control panel may continuously monitor the load resistance of its inputs/outputs to the access point, such as electronic door locks and/or sensors in or on the door. The system allows the access control panel to identify whether the access point has been tampered with, when turned on or off by a resistance value set in the system, and monitoring of the resistive load is typically done at the load panel. Typically, the electrical wiring between the load panel and the door position switch is not monitored. To prevent the possibility of tampering, the system of the present invention avoids placing the resistor network close to the load panel, which would make the circuit susceptible to tampering, cutting or shortening the circuit, by placing the wire termination resistors as close as possible to the contact point (mechanical switch or reed switch). The closer the resistive network is to the contact point, the less likely the monitoring will fail. The safest place is to integrate the resistor into the lock body.

The present invention provides enhanced security against tampering or breaking access controls by having a load resistor located on or associated with the locking mechanism, which would reduce the ability to tamper with the line. Access control manufacturers have created a variety of resistor networks for their unique systems, most commonly one thousand ohms (1K Ω) (gates closed) to two thousand ohms (2K Ω) (gates open), which are used in over fifty percent (50%) applications. In this solution, the load resistance will become infinite ohms (∞ Ω) if the line is cut, or will drop to zero ohms (0 Ω) if the circuit is shorted. The present invention allows for the design option capability of an integrated printed circuit board that will incorporate this capability to render the access control panel, which continuously monitors the status of the locking function with a set resistance value, and which can be easily adapted to accommodate any access control manufacturer's unique resistance network.

Fig. 1-5 show an embodiment of the present invention in which a configurable circuit board with an embedded resistive network is closed by an electronic connector key that engages the electronic door lock body. Referring to fig. 1, an electronic connector key 20 according to the present invention is provided for connecting selected electronic components installed in an electronic door lock 10. The electronic connector key 20 includes a connector key housing 22 shaped to be inserted and installed into the electronic door lock 10.

Connector key housing 22 may be made up of two halves 24, 26 (see fig. 4) that surround configurable circuitry 30. In the illustrated embodiment, one end of the configurable circuit 30 is a card edge connector, forming a lock side key connector 32. In the connector key housing 22, configurable circuitry 30 connects between a plurality of connection points along a card edge connector 32 and wires forming a cable 34.

The connector

key housing halves

24, 26 have

bore sections

33a, 33b, respectively, which when combined form a bore around the cable 34 in a press-fit manner. The cable 34 may form part of an external electrical wiring harness and lead to the external unit 90, and the cable may send and/or receive electronic signals communicated between the electronic components in the electronic door lock 10 and the external unit. The cable 34 may be secured to the mortise lock by a plurality of cable clamps, such as cable clamps 48, 50, and 52. The cable may enable the electronic door lock to communicate with the external unit, and the external unit may be located remotely from the electronic door lock, for example in an otherwise conventional access control panel, for monitoring a load resistance between the external unit and the electronic door lock.

In fig. 2, the cover of the mortise lock has been removed to show the components, sensors and actuators within the lock and to better illustrate how the electronic connector keys of the present invention engage the mortise lock. Fig. 2 shows an electrical connector key 20 inserted into a corresponding opening 12 in the lower right hand corner of the mortise lock 10. As further shown in fig. 3, each

half

24, 26 of connector key housing 22 is provided with notches or

recesses

44a, 44b that collectively form recess 44, and

ramp surfaces

46a, 46b that collectively form ramp 46. When the electrical connector key 20 is inserted into the opening 12, the ramp surface 46 contacts and slides under the bolt 14 inside the mortise lock 10. When the recess 44 reaches the bolt 14, the electrical connector key 20 may snap into the desired position and the bolt may removably lock the recess. When inserted and installed within the mortise lock body, the electronic connector key is shaped such that the rear portion of the connector key housing does not extend beyond the edge of the mortise lock body. The wires in the electrical cable 34 exiting the electrical connector key 20 may be directly connected to an external unit 90 (fig. 1), such as an access control panel, or may be attached to an intermediate electrical connector.

Further, the card edge connector forms a lock-side key connector 32 that can engage the lock connector 47 when the electrical connector key 20 is inserted. The connector 47 has a plurality of individual connectors that are compatible with a plurality of connection points along the card edge of the lock side key connector 32, respectively. The separate connection between connector 47 and lock side key connector 32 electrically connects circuit board 30 of connector key 20 to electronic components such as a reed switch sensor 92a that detects movement of locking tab 76 driven into and out of lock by motor 74, which engages the spindle of spindle hub 42 by being integrated with or mounted to locking tab 76 by a magnet (not shown), and a reed switch 92b that detects the position of spindle hub 42 by being mounted thereto by magnet 70. Connector 47 or some other type of electrical connection may be used for the electronics to detect the position of these and various other mechanical components within mortise lock 10. By configuring the electrical connections provided on configurable circuit board 30, the various wires within cable 34 may be connected or disconnected.

Referring to fig. 4 and 5, the key configuration may be accomplished simply by connecting or disconnecting wires 36 in cable 34 to corresponding pads 38 on circuit board 30. Alternatively, circuit board traces (not shown) interconnecting various components on the circuit board 30 may be omitted or added to achieve the desired configuration. In addition, the circuit board 30 may be provided with various cross-connects, or additional electronic components to achieve the desired configuration.

Additional electronic components may be mounted to the circuit board 30 to identify to circuitry in the lock and/or external unit what type of electronic connector key has been installed and/or to signal that a valid and authorized electronic connector key has been installed, and/or to generate a desired load resistance that may be monitored by the external unit to determine its status. In the embodiment shown in fig. 4 and 5, an electronic component in the form of a resistor 40 has been embedded in the circuit board 30, the resistor providing the desired load resistance, which can be monitored by an external unit. These line termination resistances may be used alone or configured to achieve a desired load resistance by omitting or adding electrical connections therebetween. The particular embedded circuit board configuration may be adapted to be compatible with any access control manufacturer's particular resistor network. By having the resistor network in the integrated circuit 30 within the lock body in this manner, it reduces the likelihood of tampering with the wiring without removing the mortise lock cover plate and connector key housing 22 to access the circuit board 30. Different circuit boards, including different embedded resistor networks, may be used to implement different desired connections or wires, which may be selectively connected to provide desired interconnections.

Fig. 6-9 depict another embodiment of the present invention in which the resistor network is embedded in a configurable circuit that is enclosed in a circuit housing mounted near the electronic lock body and electronically interconnected with the electronic door lock. Referring to fig. 6 and 7, a configurable circuit housing 60 is mounted adjacent to the electronic door lock body and is interconnected with the electronic door lock 10' by internal wiring harnesses 62, 64. The inner wire bundles 62, 64 may be secured to the latch by a plurality of cable clamps, such as cable clamps 68, 70, 72, 74, 76, and 78. The cable 34 'passes through the external unit 90 and the cable may send and/or receive signals that are communicated between the electronic components of the electronic door lock 10' and the external unit. Cable 34' may be secured to configurable circuit housing 60 by a plurality of cable clamps, such as cable clamps 80, 82, and 84.

Referring to fig. 8 and 9, configurable circuit 30 ' is mounted in circuit housing 60 and is electrically interconnected with the electronic components in mortise lock 10 ' by wires 36 '. Configurable circuit board 30 'may be the same as circuit board 30 or may be differently configured to meet the customer's particular needs. Internal wiring harnesses 62, 64, 66 electrically interconnect configurable circuit 30' to the electronic components within the mortise lock. By configuring the electrical connections provided on configurable circuit board 30', the different wires within cable 34 may be connected or disconnected. The configuration may be accomplished simply by connecting or disconnecting the wires 36 'in the cable 34' to the corresponding pads 38 'on the circuit board 30'. Alternatively, circuit board traces (not shown) on the circuit board 30' may be omitted or added to achieve the configuration. In addition, the circuit board 30' may be provided with various cross-connects, or additional electronic components to achieve the configuration.

Additional electronic components may be mounted on the circuit board 30' to identify to the lock and/or external unit what type of electronic connector key has been installed and/or to signal that a valid and authorized electronic connector key has been installed, or to generate a desired load resistance that may be monitored by the external unit to determine status. In the embodiment shown in fig. 8 and 9, a resistor 40 'has been embedded in the circuit board 30', which may optionally be configured as before to provide a desired load resistance that may be monitored by an external unit to determine changes in the resistance value created for one or more particular electronic components. By directly associating and locating the resistive network at the locking mechanism, rather than on the access control panel, it reduces the likelihood of tampering with the lines connecting the external unit to the electronic components.

The present invention also provides an improved method of determining access point tampering. Enhanced security against tampering or breach of access control may be achieved between the load panel and the access point by integrating a resistive network within the electronic door lock body, or a resistive network directly associated and located at and near the locking mechanism, and then monitoring the load resistance within or near the electronic lock body to determine the state of the system at the external unit.

Accordingly, the present invention accomplishes one or more of the above objects. It can reduce the likelihood that the line between the access control panel and the door access point and the electronic door lock is susceptible to tampering, cutting or shortening the monitoring circuit. It may provide an improved integrated lock body system to prevent tampering between the load panel and the access point. It may provide enhanced security against tampering or breach of access control by having a load resistor on the lock body. It may also reduce and reduce installation time and labor costs of the electronic door lock system.

While the present invention has been described in detail with reference to specific embodiments thereof, it will be apparent to those skilled in the art from the foregoing description that various alternatives, modifications, and variations can be made. It is therefore to be understood that the appended claims are intended to embrace any such alternatives, modifications and variations as falling within the true scope and spirit of the present invention.
