US 2023/0265683 A1 · LOCK DEVICE WITH A CLUTCH

Abstract

A clutch includes an outer box and an intermediate member pivotably connected to the outer box. The intermediate member is coupled with an outer handle to pivot therewith. A torsion spring is disposed between the intermediate member and the outer box and biases the intermediate member to an initial position. A coupling member is pivotably mounted between the intermediate member and the outer box and is operatively connected to a first latch of a latch device of a lock device. When the coupling member and the intermediate member are jointly pivotable, pivotal movement of the outer handle causes the first latch to move from the latching position or the unlatching position. When the coupling member is not jointly pivotable with the intermediate member, pivotal movement of the outer handle is incapable of causing movement of the first latch. A lock device with the clutch is also disclosed.

Dependent claims

A lock device comprising:

a latch device including a first latch movable between a latching position and an unlatching position;
an outer escutcheon to an outer side of the latch device;
an outer handle pivotably mounted to an outer side of the outer escutcheon;
and
a clutch disposed on the outer side of the latch device and located on an inner side of the outer escutcheon, wherein the clutch includes a pivotable intermediate member coupled to the outer handle to pivot therewith, wherein the clutch further includes a coupling member operatively coupled to the first latch, wherein the coupling member is configured to or not to jointly pivot with the intermediate member, wherein when the coupling member and the intermediate member are jointly pivotable, pivotal movement of the outer handle causes the first latch to move from the latching position or the unlatching position, and wherein when the coupling member is not jointly pivotable with the intermediate member, pivotal movement of the outer handle is incapable of causing movement of the first latch.

2 more elements

The lock device as claimed in claim 10, further comprising an inner operating device mounted to another side of the latch device, wherein the latch device further includes a second latch, wherein the inner operating device includes a main board and a sensor electrically connected to the main board, wherein the inner operating device further includes an inner operating knob operatively connected to the second latch, wherein the inner operating knob is configured to activate the sensor, wherein rotation of the inner operating knob causes movement of the second latch between an extended position and a retracted position, wherein when the second latch is in the extended position, the sensor is in one of an activated state and a non-activated state, and the driving device is not operable, such that the clutch member is incapable of moving from the disengagement position to the engagement position, and wherein when the second latch is in the retraced position, the sensor is in another of the activated state and the non-activated state, and the driving device is operable, such that the clutch member is movable from the disengagement position to the engagement position.

A clutch adapted to be mounted to an outer side of a latch device of a lock device and configured to be operatively connected to an outer operating device of the lock device, with the clutch comprises:

an outer box;
an intermediate member pivotably connected to the outer box, wherein the intermediate member is configured to couple with an outer handle of the outer operating device to pivot therewith;
a torsion spring disposed between the intermediate member and the outer box, wherein the torsion spring biases the intermediate member to an initial position, and
a coupling member pivotably mounted between the intermediate member and the outer box, wherein the coupling member is configured to be operatively connected to a first latch of the latch device, wherein the coupling member is configured to control the intermediate member to or not to pivot jointly with the intermediate member, wherein when the coupling member and the intermediate member are jointly pivotable, pivotal movement of the outer handle causes the first latch to move from the latching position or the unlatching position, and wherein when the coupling member is not jointly pivotable with the intermediate member, pivotal movement of the outer handle is incapable of causing movement of the first latch.
