  • Patent number: 12227967
    Abstract: An exemplary catch assembly is configured for installation into a spindle, and generally includes a holder, a first catch, a second catch, and a bias mechanism. The holder is configured for mounting within the spindle. The first catch is mounted for movement relative to the holder between a first projected position and a first depressed position. The second catch is mounted for movement relative to the holder between a second projected position and a second depressed position. The bias mechanism biases the first catch toward the first projected position and biasing the second catch toward the second projected position.

  • Patent number: 8555685
    Abstract: An electrically controlled door lock device with a lockset with an inside handle, an outside handle, a spring loaded continuous spindle, biased to maintained a lockset's latch in a projected position and connecting the lockset and the outside handle, a first half and a second half of a clutch connecting the continuous spindle and the inside handle with a spring maintaining the second half of the clutch in predetermined position relative to the first half of the clutch. There is also a mechanical means blocking the first half of the clutch from rotation and electromechanical means controlling the blocking means, the mechanical means built into the second half of the clutch, allowing the second half of the clutch a predetermined degree of free rotation before it engages with the first half of the clutch, the mechanical means built into second half of the clutch, mechanically inhibiting the blocking means.

  • Patent number: 7207199
    Abstract: A deadbolt mechanism including a lock out mechanism that functions to disable the operation of the deadbolt from at least one side of the deadbolt mechanism. The deadbolt mechanism includes a deadbolt, key cylinder, housing, turn knob and a shaft that connects the key cylinder and turn knob. To place the deadbolt mechanism in lock out mode, the turn knob is moved to the locked positioned and then pulled outward away from the door. By pulling the knob outward, the shaft engages a portion of the housing which prevents rotation of the shaft and thereby prevents movement of the deadbolt from the locked position.

  • Patent number: 6553799
    Abstract: A push button door locking mechanism including a push button mounted on a push button carrier housed within an inside spindle of a door lock assembly, a main retractor co-rotatingly attached to the spindle, and an inner cam aligned axially with the push button carrier. The inner cam has a flange portion extending substantially perpendicularly from a driver bar portion of the inner cam. The locking mechanism also includes a locking catch assembly having a first end and a second end. The first end includes a head portion formed to matingly engage the push button carrier. The second end is coupled to a locking wing. The locking catch assembly has a locked position wherein the locking wing matingly engages the flange preventing rotation of the flange with respect to the main retractor and an unlocked position allowing rotation of the flange with respect to the main retractor.

  • Patent number: 6122946
    Abstract: Latch assemblies are disclosed including a latch bolt mounted on a casing for relative movement between an extended latching position and a retracted release position, a first actuator operable from the inner side of the assembly to cause movement of the latch bolt to the release position, a lock operable from the inner side of the assembly to adopt an active condition thus render the first actuator inoperable, a second actuator operable from an outer side of the assembly to cause movement of the latch bolt to the release position, and a lock release responsive to operation of the second actuator to render the lock inactive.

  • Patent number: 5865050
    Abstract: A locking cover for a dead bolt lock assembly that permits a user to put it in one of three positions: neutral, locked and unlocked. The cover in the neutral position permits the operation of the bolt lock assembly normally. The other positions limit the rotational travel of the actuating shaft to one quarter of a turn. The actuating shaft is rotated by turning the locking cover that includes a central tubular cylinder for selective engagement with the actuating shaft. A pin mounted on the interior of the cover is receivable within one of three holes on an annular base plate that limits the rotation of the actuating shaft.

  • Patent number: 4255953
    Abstract: One part of a key-in-knob lock set functions in a normal manner such that when the lock set is unlocked, either the outside or inside knob can be manipulated to open the door by withdrawing the latch bolt from a normal spring latch extended position. When, instead, the lock set is locked, the latch bolt is extended an exceptionally long distance into the frame to a dead bolt position. Extension and retraction of the latch bolt to and from dead bolt position is accomplished by manipulation of a main cam through the agency of a key in the outside knob or a turn button on the inside knob.For withdrawing the latch bolt from the normal spring latch extended position an escutcheon housing for the outside knob or a corresponding escutcheon housing for the inside knob serves, by moving transversely of the axis of rotation of the knob, to rotate a radially extending finger on the spindle which, acting through the main cam, withdraws the latch bolt.

  • Patent number: 4031725
    Abstract: A dead bolt type door lock including a combined dead bolt member and latch which engages a common locking recess in a door jamb around a door in which the lock is mounted. The door lock utilizes a standard keyed lock assembly in combination with a latch fitted in sliding relationship within a channel shaped dead bolt member so that when the dead bolt member is retracted into the door the latch functions in a conventional manner and when the dead bolt is extended over the latch into the door jamb opening the door is secured against the normal techniques of unauthorized entry commonly accomplished by the use of credit cards and the like. The lock includes linkage and latch assemblies for manipulating and holding the latch and dead bolt sleeve at the various operating positions at which the lock is locked and released. The dead bolt sleeve is selectively operable from both the interior and exterior sides of the door.
