Abstract

An electronic door lock mounts to a door and includes an inner side and an outer side. The electronic door lock is operable to control access to an access controlled area positioned adjacent the inner side of the door. The electronic door lock includes an outer base connected to the outer side of the door, an inner base connected to the inner side of the door, a locking mechanism coupled to the door and movable between a locked position and an unlocked position in response to a control signal, and a control circuit disposed within the inner base and operable to generate the control signal in response to an input credential. An attachment interface is at least partially formed as part of the outer base. Each of a plurality of different types of credential readers is selectively attachable and removable from the attachment interface when the outer base is attached to the door to electrically connect a selected one of the plurality of different types of credential readers to the control circuit to provide the input. A communication module is connected to the control circuit, and the communication module is operable to communicate with a device that is separate from the electronic door lock.

Claims19

Dependent claims

An electronic door lock that mounts to a door, the door including an inner side and an outer side and the electronic door lock operable to control access to an access controlled area positioned adjacent the inner side of the door, the electronic door lock comprising:

an outer base connected to the outer side of the door;
an inner base connected to the inner side of the door;
a locking mechanism coupled to the door and movable between a locked position and an unlocked position in response to a control signal;
a control circuit disposed within the inner base and operable to generate the control signal in response to an input credential;
an attachment interface at least partially formed as part of the outer base;
a plurality of different types of credential readers each selectively attachable and removable from the attachment interface when the outer base is attached to the door to electrically connect a selected one of the plurality of different types of credential readers to the control circuit to provide the input, each of the credential readers being fully supported by the outer base when attached to the attachment interface;
a communication module connected to the control circuit, the communication module operable to communicate with a device that is separate from the electronic door lock;
a first anti-tamper wall positioned between the attachment interface and the locking mechanism to inhibit access to the locking mechanism from the attachment interface;
and
a second anti-tamper wall positioned between the first anti-tamper wall and the locking mechanism to inhibit access to the locking mechanism.

7 more elements

an outer base connected to and supported by the outer side;
an inner base supported by the inner side;
a locking mechanism coupled to the door and moveable between a locked position and an unlocked position;
a control circuit disposed within the inner base and configured to selectively move the locking mechanism between the locked position and the unlocked position to control access to the access controlled area;
an attachment interface coupled to the outer base and including a mounting portion and a first connector that extends from the mounting portion, the first connector in electrical communication with the control circuit;
a first anti-tamper wall positioned between the attachment interface and the locking mechanism to inhibit access to the locking mechanism from the attachment interface;
a second anti-tamper wall positioned between the first anti-tamper wall and the locking mechanism to inhibit access to the locking mechanism;
an outer escutcheon supported by at least one of the outer base and the door, the outer escutcheon positioned to substantially cover the outer base and including an aperture positioned adjacent the attachment interface to expose the attachment interface;
and
a credential reader that includes a surface sized and shaped to generally correspond to the mounting portion and a second connector configured to mate with the first connector, the credential reader removably mountable to the attachment interface to electrically connect the credential reader to the control circuit, such that when the credential reader is mounted to the attachment interface, the outer base fully supports the credential reader and when the credential reader is not mounted to the attachment interface, the outer base remains connected to the outer side of the door.

7 more elements

a locking mechanism coupled to the door and moveable between a locked position and an unlocked position;
an attachment interface coupled to the outer side and including a mounting portion;
one of a keypad, proximity detector, proximity detector with built-in keypad, magnetic stripe reader, magnetic stripe reader with built-in keypad, and biometric reader, each of the keypad, proximity detector, proximity detector with built-in keypad, magnetic stripe reader, magnetic stripe reader with built-in keypad, and biometric reader removably mountable to the mounting portion such that the attachment interface fully supports the one of the keypad, proximity detector, proximity detector with built-in keypad, magnetic stripe reader, magnetic stripe reader with built-in keypad, and biometric reader;
a control circuit coupled to the door and configured to selectively move the locking mechanism between the locked position and the unlocked position to control access to the access controlled area, the control circuit including software or firmware operable to receive an input from each one of the keypad, proximity detector, proximity detector with built-in keypad, magnetic stripe reader, magnetic stripe reader with built-in keypad, and biometric reader;
an outer base supported by the outer side, wherein the attachment interface is coupled to the outer base, and further including a first anti-tamper wall positioned between the attachment interface and the locking mechanism to inhibit access to the locking mechanism from the attachment interface;
and
a second anti-tamper wall positioned between the first anti-tamper wall and the locking mechanism to inhibit access to the locking mechanism.
