Abstract

A door lock assembly for operating an electronic door lock module to lock and unlock a door. The door lock assembly comprises a housing extending along a central longitudinal axis from a first end to a second end, the housing comprising a peripheral wall which extends from the first end to the second end and is radially spaced around the central longitudinal axis. An interface is configured to connect the door lock assembly to the electronic door lock module for operating a lock bolt. A primary locking arrangement for locking and unlocking the door comprises a keypad for inputting information to operate the electronic door lock, and the door lock assembly comprises a secondary locking arrangement for locking and unlocking the door. At least a portion of the peripheral wall is arcuate and curves around the central longitudinal axis of the housing, and the keypad is provided on the peripheral wall and curves around the central longitudinal axis of the housing.

2 . A door lock assembly according to claim 1 , in which the keypad is provided on an upper side of the housing.

3 . A door lock assembly according to claim 1 , in which the keypad faces generally upward in use.

4 . A door lock assembly according to claim 1 , in which the keypad extends around an upper part of the circumference of the peripheral wall.

5 . A door lock assembly according to claim 1 , in which the arcuate portion of the peripheral wall comprises an arcuate surface which curves around the central longitudinal axis.

6 . A door lock assembly according to claim 5 , in which a plane of the keypad is coextensive with at least part of the arcuate surface.

7 . A door lock assembly according to claim 1 , in which the keypad comprises a plurality of keys which are arranged to extend radially around the central longitudinal axis.

8 . A door lock assembly according to claim 1 , in which the housing has a generally frustoconical shape.

9 . A door lock assembly according to claim 1 , in which the first end of the housing is arranged, in use, to locate adjacent to a surface of a door.

10 . A door lock assembly according to claim 9 , in which the housing is arranged, in use, to protrude away from the door and the protruding housing enables a user to place a palm of their hand over the second end of the housing and for their fingers to operate the keypad.

11 . A door lock assembly according to claim 1 , in which the secondary locking mechanism comprises a key lock mechanism.

12 . A door lock assembly according to claim 11 , in which the key lock mechanism comprises a cylinder lock.

13 . A door lock assembly according to claim 1 , comprising a mounting plate arranged to locate between the door and the electronic door lock on an opposite side of the door to the lock assembly in use.

14 . A door lock assembly according to claim 13 , in which the mounting plate comprises a recess for receiving the Bluetooth antenna.

15 . A door lock assembly according to claim 1 , comprising a radio-frequency window aperture to allow radio-frequency signals to pass into and out of the housing.

16 . A door lock assembly according to claim 15 , in which the radio-frequency window aperture is closed by a window panel comprising a radiotransparent material and the window panel substantially seals the radio-frequency window aperture to prevent ingress of fluids.

17 . A door lock assembly according to claim 1 , wherein the door lock assembly comprises the electronic door lock and the lock bolt.

18 . A door comprising a door lock assembly according to claim 1 .

19 . A method of installing on a door a door lock assembly for operating an electronic door lock module to lock and unlock the door, the door lock assembly comprising:

a housing extending along a central longitudinal axis from a first end to a second end, the housing comprising a peripheral wall which extends from the first end to the second end and is radially spaced around the central longitudinal axis;

an interface configured to connect the door lock assembly to the electronic door lock module for operating a lock bolt;

a primary locking arrangement for locking and unlocking the door, the primary locking arrangement comprising a keypad for inputting information to operate the electronic door lock;
