Abstract
A door entry system includes control means for controlling operation of the door entry system and a deadbolt assembly that is operable to selectively lock a door. The deadbolt assembly includes: a first bolt member movable between an extended and a retracted position; switch means arranged on said first bolt member, the switch means conveying a signal to the control means to move said first bolt member between the extended and retracted positions when the switch means is activated; and, driving means for selectively moving the first bolt member between the extended and retracted positions.
Claims28
A door entry system comprising:
- control means for controlling operation of the door entry system;
- and,
- a deadbolt assembly that is operable to selectively lock a door, said deadbolt assembly including:
- a first bolt member movable between an extended position and a retracted position;
- a switch mounted to said first bolt member, said switch conveying a signal to the control means to move said first bolt member between the extended and retracted positions when said switch is activated, and
- driving means for selectively moving the first bolt member between the extended and retracted positions.

- control means for controlling operation of the door entry system;
- a deadbolt assembly that is operable to selectively lock a door, said deadbolt assembly including:
- a bolt member movable between an extended position and a retracted position;
- switch means arranged on said bolt member, said switch means conveying a signal to the control means to move said bolt member between the extended and retracted positions when said switch means is activated;
- and,
- driving means for selectively moving the bolt member between the extended and retracted positions;
- and,
- a deadbolt receiving assembly that selectively receives the bolt member, said deadbolt receiving assembly including:
- a receiving region that receives said bolt member when the bolt member is in the extended position, said dead bolt receiving region not receiving the bolt member when the bolt member is in the retracted position;
- and,
- a bolt section that is selectively extendable into and retractable from the receiving region, said bolt section being extended to activate said switch means on the bolt member.

A door entry system comprising:
- control means for controlling operation of the door entry system;
- a deadbolt assembly that is operable to selectively lock a door, said deadbolt assembly including:
- a first bolt member movable between an extended position and a retracted position;
- a switch, said switch conveying a signal to the control means to move said first bolt member between the extended and retracted positions when said switch is activated;
- and,
- driving means for selectively moving the first bolt member between the extended and retracted positions;
- and,
- a second bolt member that is selectively engaged with and disengaged from the first bolt member such that when engaged the first and second bolt members move in unison with one another and when disengaged the first and second bolt members are independently movable with respect to one another.

A door entry system comprising:
- a deadbolt assembly that is operable to selectively lock a door, said deadbolt assembly including first and second members that are selectively engaged with and disengaged from one another such that when engaged they move in unison with one another and when disengaged they are independently movable with respect to one another;
- drive means coupled to the second member such that the first member is selectively movable by the drive means between extended and retracted positions when the first and second members are engaged with one another and the first member is not movable by the drive means between the extended and retracted positions when the first and second members are disengaged from one another;
- and,
- control means for controlling the drive means.

3 more elements
A door entry system comprising:
- a deadbolt member movable between an extended and a retracted position;
- switch means arranged in or on the deadbolt member, said switch means generating a signal to effect movement of said deadbolt member to the extended or retracted position when said switch means is activated;
- motor means for moving the dead bolt member between the extended and retracted positions;
- a deadbolt bolt lever body housing means dimensioned to receive said deadbolt member when in its extended position, said deadbolt bolt lever body housing means including therein a second movable bolt section engagable with said switch means to activate said switch means.

A door entry system comprising:
- control means for controlling operation of the door entry system;
- a deadbolt assembly that is operable to selectively lock a door, said deadbolt assembly including:
- a bolt member movable between an extended position and a retracted position;
- trigger means mounted to the bolt member, said trigger means conveying a signal to the control means to move said bolt member between the extended and retracted positions when said trigger means is triggered;
- and,
- driving means for selectively moving the bolt member between the extended and retracted positions;
- and,
- a deadbolt receiving assembly arranged opposite the deadbolt assembly, said deadbolt receiving assembly including:
- a receiving region that receives said bolt member when the bolt member is in the extended position thereby locking the door, said deadbolt receiving region not receiving the bolt member when the bolt member is in the retracted position thereby not locking the door;
- and,
- activation means for selectively triggering the trigger means.
