Abstract

A combination door latch and deadbolt assembly that has first and second configurations for use with a door having a deadbolt aperture and a latchbolt aperture spaced by either a first vertical distance or a second vertical distance. The second vertical distance is less than the first vertical distance. In the first configuration, an insert slide is connected to an interconnect slide for vertical movement with the interconnect slide and the interconnect slide is operably connected to a deadbolt assembly via the insert slide. The insert slide and interconnect slide are movable vertically to move a deadbolt from an extended position to a retracted position in response to movement of an interior actuator from a first position to a second position. In the second configuration, the interconnect slide is operably connected to the deadbolt assembly without the insert slide.

Dependent claims

A combination door latch and deadbolt assembly for use with a door having a deadbolt aperture and a latchbolt aperture that extend through the door, the latchbolt aperture spaced from the deadbolt aperture by a vertical distance, the assembly comprising:

a deadbolt assembly including a deadbolt movable between an extended position and a retracted position;
a latchbolt assembly including a latchbolt movable between an extended position and a retracted position;
an interior assembly including an actuator manually movable from a first position to a second position to move the latchbolt from the extended position to the refracted position;
an interconnect slide;
and
an insert slide configured to be removably coupled to the interconnect slide;
the combination door latch and deadbolt assembly having first and second configurations, the first configuration being used when the door has the latchbolt aperture spaced from the deadbolt aperture by a first vertical distance, and the second configuration being used when the door has the latchbolt aperture spaced from the deadbolt aperture by a second vertical distance less than the first vertical distance,
wherein, in the first configuration, the insert slide is connected to the interconnect slide for vertical movement with the interconnect slide and the interconnect slide is operably connected to the deadbolt assembly via the insert slide, the interconnect slide and the insert slide are movable vertically from a first position to a second position to move the deadbolt from the extended position to the refracted position in response to movement of the actuator from the first position to the second position, and
wherein, in the second configuration, the insert slide is not connected to the interconnect slide for vertical movement with the interconnect slide and the interconnect slide is operably connected to the deadbolt assembly, and the interconnect slide is movable vertically from a first position to a second position to move the deadbolt from the extended position to the retracted position in response to movement of the actuator from the first position to the second position.

6 more elements

a deadbolt assembly including a deadbolt movable between an extended position and a retracted position;
a latchbolt assembly including a latchbolt movable between an extended position and a retracted position;
an interior assembly including an actuator manually movable from a first position to a second position to move the latchbolt from the extended position to the refracted position;
a thumb turn actuator manually operable to move the deadbolt between the retracted position and the extended position;
an interior escutcheon including an elongated thumb turn aperture for the thumb turn actuator,
the combination door latch and deadbolt assembly having first and second configurations, the first configuration being used when the door has the latchbolt aperture spaced from the deadbolt aperture by a first vertical distance, and the second configuration being used when the door has the latchbolt aperture spaced from the deadbolt aperture by a second vertical distance less than the first vertical distance, and
wherein the elongated thumb turn aperture has a length sufficient to permit the thumb turn actuator to extend through the thumb turn aperture when the thumb turn actuator is located at a first vertical position in response to the assembly being configured for use in the first configuration and to permit the thumb turn actuator to extend through the thumb turn aperture when the thumb turn actuator is located at a second vertical position in response to the assembly being configured for use in the second configuration.

4 more elements

a deadbolt assembly including a deadbolt movable between an extended position and a retracted position;
a latchbolt assembly including a latchbolt movable between an extended position and a retracted position;
an interior actuator manually movable from a first position to a second position to move the latchbolt from the extended position to the retracted position;
an interconnect slide movable vertically to move the deadbolt from the extended position to the retracted position in response to movement of the interior actuator from the first position to the second position;
and
a base plate configured to be coupled to the door and the interconnect slide coupled to the base plate such that the base plate guides vertical movement of the interconnect slide;
the combination door latch and deadbolt assembly having first and second configurations, the first configuration being used when the door has the latchbolt aperture spaced from the deadbolt aperture by a first vertical distance, and the second configuration being used when the door has the latchbolt aperture spaced from the deadbolt aperture by a second vertical distance less than the first vertical distance,
wherein the interior actuator is in a first fixed position relative to the base plate when the assembly is in the first configuration, and
wherein the interior actuator is in a second fixed position relative to the base plate vertically spaced from the first fixed position when the assembly is in the second configuration.
