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. A coupling cartridge of an electronic lock can easily be 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.

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, wherein:

a coupling apparatus selectively couples the exterior handle to the latch, the coupling apparatus being activated by a non-contact signal from a transponder;
an authenticator circuit authenticates the signal from the transponder and controls an 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,
wherein the coupling apparatus comprises a force transfer member and an outer coupling member, wherein the force transfer member and outer coupling member are coupled via camming blocks in such a manner that a movement of the force transfer member causes a movement of the camming blocks, wherein said movement of the force transfer member is not transferred through the camming blocks to the outer coupling member in a decoupled state and is transferred through the camming blocks to the outer coupling member in a coupled state,
wherein a blocking element can be positioned between the camming blocks in the coupled state, the blocking element preventing the camming blocks from giving way and thus coupling the force transfer member with the outer coupling member in the coupled state, and wherein the blocking element moves out of the way of the camming blocks in the decoupled state,
further comprising a security apparatus that prevents the blocking element from being moved in the presence of an externally applied magnetic field,
wherein said security apparatus comprises a movable security arm which is caused to actively pivot to a secure position when an external magnetic field is applied, wherein the blocking element cannot be moved between the camming blocks when said security arm has been moved in said secure position such that the lock cannot change from a decoupled to a coupled state.

4 more elements

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,
further comprising a security apparatus that prevents the blocking element from being moved in the presence of an externally applied magnetic field,
wherein said security apparatus comprises a movable security arm which is caused to actively pivot to a secure position when an external magnetic field is applied, wherein the blocking element cannot be moved between the camming blocks when said security arm has been moved in said secure position such that the lock cannot change from a decoupled to a coupled state.
