Electronic lock control and sensor module for a wireless system

A retrofit assembly for a cylindrical door lock of the type having an opening spindle for controlling a latch bolt of the door lock and having a latching spindle coaxial with the opening spindle which controls a lock mechanism of the door lock when rotated relative to the opening spindle, the retrofit assembly comprising:

• an electronically controllable actuating member couplable to the latching spindle and adapted to be positioned on the cylindrical door lock such that the opening spindle is engageable with an inner door knob of the cylindrical door lock;
• wherein the actuating member rotates the latching spindle relative to the opening spindle when an appropriate electronic signal is received by the actuating member, the rotation causing the lock mechanism to go into an unlocked or a locked state, wherein the actuating member includes a first collar dimensioned to freely rotate around the opening spindle and a second collar which is keyed to fit around the opening spindle.

• wherein the actuating member rotates the latching spindle relative to the opening spindle when an appropriate electronic signal is received by the actuating member, the rotation causing the lock mechanism to go into an unlocked or a locked state, wherein the actuating member includes a sleeve positioned around the latching spindle and located between the opening spindle and the latching spindle, the sleeve having an arm for driving the rotation of the sleeve.

A method for retrofitting a cylindrical door lock of the type having a latching spindle which controls a lock mechanism of the cylindrical door lock when rotated relative to an opening spindle of the cylindrical door lock, the method comprising:

• installing an electronically controllable actuating member on the latching spindle so that the opening spindle includes an exposed end for engaging with an inner door knob, wherein the actuating member rotates the latching spindle relative to the opening spindle when an appropriate electronic signal is received by the actuating member which causes the lock mechanism to go into an unlocked or a locked state, wherein installing includes slide fitting a first collar around the opening spindle, wherein the first collar includes a keyed hole dimensioned to couple the first collar with the opening spindle, wherein installing further includes slide fitting a second collar around the opening spindle, the second collar including a hole which is dimensioned so that the second collar freely rotates around the opening spindle, the second collar including an adapter member which couples with the latching spindle to rotate the latching spindle.

• installing an electronically controllable actuating member on the latching spindle so that the opening spindle includes an exposed end for engaging with an inner door knob, wherein the actuating member rotates the latching spindle relative to the opening spindle when an appropriate electronic signal is received by the actuating member which causes the lock mechanism to go into an unlocked or a locked state, wherein installing includes slide fitting a sleeve around the latching spindle so that it is positioned between the latching spindle and the opening spindle.

A lock system comprising:

• a cylindrical door lock of the type having an opening spindle for controlling a latch bolt of the door lock and having a latching spindle coaxial with the opening spindle which controls a lock mechanism of the door lock when rotated relative to the opening spindle, wherein the latching spindle is rotatable by a manually operated key from a first side of the door lock and by a manual operated locking member on a second side of the door lock;
• and
• an electrically controlled actuator assembly mountable to the cylindrical door lock to electrically control the rotation of the latching spindle relative to the opening spindle, wherein the electrically controlled actuator assembly is positioned such that it does not interfere with operation of the manually operated key or the manual operated locking member.
