Abstract
An electric door lock includes a latching unit, and first and second rotatable members. The latching unit is movable between latching and unlatching positions.
The first rotatable member is provided with a first protrusion, and is rotatable between first and second angular positions corresponding to the latching and unlatching positions of the latching unit. The second rotatable member is provided with a second protrusion, and is rotatable in a first rotational direction such that the second protrusion pushes the first protrusion so as to move the first rotatable member from the first angular position to the second angular position, and in a second rotational direction such that the second protrusion pushes the first protrusion so as to move the first rotatable member from the second angular position back to the first angular position.
The first rotatable member is provided with a first protrusion, and is rotatable between first and second angular positions corresponding to the latching and unlatching positions of the latching unit. The second rotatable member is provided with a second protrusion, and is rotatable in a first rotational direction such that the second protrusion pushes the first protrusion so as to move the first rotatable member from the first angular position to the second angular position, and in a second rotational direction such that the second protrusion pushes the first protrusion so as to move the first rotatable member from the second angular position back to the first angular position.
Claims (10)
1. An electric door lock, comprising:
an internal lock housing formed with a handle mounting hole, and defining an accommodating space;
a latching unit movable between latching and unlatching positions;
a manual operating member mounted rotatably on said internal lock housing, extending into said accommodating space through said handle mounting hole, and coupled to said latching unit, said manual operating member being rotatable relative to said internal lock housing between a first angular position so as to dispose said latching unit at the latching position, and a second angular position so as to dispose said latching unit at the unlatching position;
a first rotatable member disposed in said accommodating space in said internal lock housing, coupled to said manual operating member so as to be co-rotatable therewith between the first and second angular positions, and provided with a first protrusion;
a second rotatable member disposed in said accommodating space in said internal lock housing, mounted rotatably on said internal lock housing, and provided with a second protrusion, said second rotatable member being rotatable relative to said internal lock housing in a first rotational direction such that said second protrusion pushes said first protrusion so as to move said first rotatable member from the first angular position to the second angular position, and in a second rotational direction opposite to the first rotational direction such that said second protrusion pushes said first protrusion so as to move said first rotatable member from the second angular position back to the first angular position; and an electric driving unit mounted in said accommodating space in said internal lock housing and operable so as to drive rotation of said second rotatable member.
an internal lock housing formed with a handle mounting hole, and defining an accommodating space;
a latching unit movable between latching and unlatching positions;
a manual operating member mounted rotatably on said internal lock housing, extending into said accommodating space through said handle mounting hole, and coupled to said latching unit, said manual operating member being rotatable relative to said internal lock housing between a first angular position so as to dispose said latching unit at the latching position, and a second angular position so as to dispose said latching unit at the unlatching position;
a first rotatable member disposed in said accommodating space in said internal lock housing, coupled to said manual operating member so as to be co-rotatable therewith between the first and second angular positions, and provided with a first protrusion;
a second rotatable member disposed in said accommodating space in said internal lock housing, mounted rotatably on said internal lock housing, and provided with a second protrusion, said second rotatable member being rotatable relative to said internal lock housing in a first rotational direction such that said second protrusion pushes said first protrusion so as to move said first rotatable member from the first angular position to the second angular position, and in a second rotational direction opposite to the first rotational direction such that said second protrusion pushes said first protrusion so as to move said first rotatable member from the second angular position back to the first angular position; and an electric driving unit mounted in said accommodating space in said internal lock housing and operable so as to drive rotation of said second rotatable member.
2. The electric door lock as claimed in Claim 1, wherein said first rotatable member includes a ring portion that is sleeved securely on said manual operating member so as to be co-rotatable therewith between the first and second angular positions, said first protrusion extending radially and outwardly from said ring portion of said first rotatable member.
3. The electric door lock as claimed in Claim 2, wherein said ring portion of said first rotatable member is formed with a pair of diametrically disposed engaging recesses, said manual operating member having a pair of axially extending arms, each of which engages a respective one of said engaging recesses in said ring portion of said first rotatable member.
4. The electric door lock as claimed in Claim 1, wherein said second rotatable member is disposed around said manual operating member, and is in the form of a gear, said second protrusion protruding axially from said gear toward said first rotatable member.
5. The electric door lock as claimed in Claim 1, wherein said first protrusion is made from a resilient material and has a rounded portion.
6. The electric door lock as claimed in Claim 1, wherein said second protrusion has a substantially trapezoidal shape.
7. The electric door lock as claimed in Claim 1, further comprising:
an external lock housing; and a lock member mounted on said external lock housing, extending into said external lock housing, and coupled to said latching unit, said lock member being operable so as to move said latching unit between the latching and unlatching positions.
an external lock housing; and a lock member mounted on said external lock housing, extending into said external lock housing, and coupled to said latching unit, said lock member being operable so as to move said latching unit between the latching and unlatching positions.
8. The electric door lock as claimed in Claim 7, further comprising an external handle unit mounted on said external lock housing, and operable so as to rotate relative to said external lock housing, said external handle unit being associated operably with said latching unit such that operation of said external handle unit is enabled when said latching unit is disposed at the unlatching position, and such that operation of said external handle unit is disabled when said latching unit is disposed at the latching position.
9. The electric door lock as claimed in Claim 1, further comprising a switching unit for deactivating said electric driving unit when said first rotatable member has been moved from one of the first and second angular positions to the other of the first and second angular positions.
10. The electric door lock as claimed in Claim 9, wherein said switching unit includes a sensing element that is coupled electrically to said electric driving unit and that is operable so as to deactivate said electric driving unit when actuated, a first actuator that is provided on said first rotatable member, and that actuates said sensing element when said first rotatable member is disposed at the second angular position, and a second actuator that is provided on said first rotatable member, and that actuates said sensing element when said first rotatable member is disposed at the first angular position.
