US 2007/0176437 A1 · ELECTRONIC ACCESS CONTROL HANDLE SET FOR A DOOR LOCK

Abstract

The present invention provides for a handle set for a lock with a latch, the handle set having an authentication circuit and actuator in the interior handle that allow access to authenticated transponders. The present invention also provides a device and method for transmitting a rotational movement and force in an electronic lock, wherein the transmission takes place in a coupled state and not in a decoupled state and wherein the transmission of force does not damage an actuator that requires little energy to change between the coupled and decoupled states. The handle set can include a coupling cartridge that can be easily handed. The electronic lock can be retrofitted in installed mortise locks and used with cylindrical locks. The electronic lock can include a security feature that prohibits the electronic lock from changing between the coupled and decoupled states.

Claims26

Dependent claims

In a handle set for a lock with a latch, the handle set being for a door that is between an interior handle and an exterior handle of the handle set, the door having a central plane, the improvement wherein:

a coupling apparatus selectively couples the exterior handle to the latch, the coupling apparatus including an actuator and being activated by a non-contact signal from a transponder;
and
an authenticator circuit authenticates the signal from the transponder and controls the actuator;
wherein the authenticator circuit and the actuator are positioned on an interior side of the central plane of the door and at least partially housed in the interior handle.

1 more element

Electronic door locking and lever assembly comprising:

an exterior handle and an interior handle positioned on opposite sides of a door, the exterior and interior handles linked with a coupling apparatus to actuate a latch member for opening the door from the inside and the outside, respectively, the coupling apparatus comprising a drive and a take-off, the take-off comprising a latch actuator to actuate the latch member;
an access control device which in response to an authorized wireless signal from an authorization device actuates the coupling apparatus so that the coupling apparatus can be changed between a coupled and decoupled state;
and
a coupling element which is linked to the take-off and the interior handle,
wherein when the coupling apparatus is in a coupled state, the drive is coupled to the take-off wherein a movement of the exterior handle can be transmitted from the drive to the take-off to actuate the latch member to open the door;
wherein when the coupling apparatus is in a decoupled state, the drive is decoupled from the take-off so that a movement of the exterior handle does not operate the take-off to actuate the latch member to open the door;
wherein when the interior handle is moved, the movement is transmitted to the coupling element which moves the take-off so that the latch member can be operated when the coupling apparatus is in a coupled or decoupled state;
wherein the drive is coupled to the take-off by at least one camming block that transmits torque from the drive to the take-off when the camming block is blocked by a blocking element in the coupled state, and the blocking element is moved out of the way of the camming block in the decoupled state so that the camming block does not exert torque between the drive and the take-off.
