Condition Indicators Patents (Class 70/432)
  • Patent number: 10125522
    Abstract: A lockset is actuable by pivoting a handle about a longitudinal axis of the lockset by rotating the handle and by pivoting the handle about an axis transverse to the lockset axis, such as by pushing or pulling. The lockset includes an inside handle and an outside handle, each associated with an independent mechanism, each of which can independently actuate the lockset. A locking mechanism prevents actuation of a first one of the independent handle mechanisms without affecting operation of the other handle mechanism. Upon actuation of the other handle mechanism, a retractor engages a surface of the locking mechanism and removes it from engagement with the first locking mechanism. An adjustment ring has a first configuration that centers the lockset in a door having a first standard thickness and a second configuration that centers the lockset in a door having a second standard thickness.

  • Patent number: 8881558
    Abstract: A lock for luggage, travelcases, briefcases and the like that can be unlocked by setting a combination using a combination mechanism of the lock, and, alternatively, by using a key in a key mechanism of the lock. An indicator of the lock moves to signal when the lock has been unlocked by use of the key mechanism. In some embodiments the indicator can only be reset after the lock has been unlocked using the combination mechanism. In some embodiments the indicator is automatically reset when the lock is unlocked using the combination mechanism. In some embodiments the lock is a padlock that has a shackle defined, at least in part, by a flexible cable.

    Abstract: A door lock indicator and method for use by occupants in an interior space to confirm if a lock of a door handle of a door is in a locked or an unlocked position. An inside handle of the door handle must always be free to open the door for immediate exit. When a locking mechanism is in a first position, the locking mechanism aligns with an indicator mechanism to provide an indication that the door handle is in the unlocked position. When the locking mechanism is in a second position, the locking mechanism does not align with the indicator mechanism to provide an indication that the door handle is the locked position.

  • Patent number: 7866195
    Abstract: A door lock indicator device is disclosed. The door lock indicator device can include a rotatable portion, a lock status display, and a switch (e.g., a button). The rotatable portion can define an opening shaped to receive a key blade. The door lock indicator device can be installed on a face of a door lock with the opening aligned with a keyhole of the door lock. Rotating a key blade within a keyway of the door lock can cause the rotatable portion to rotate with the door lock's cylinder. The lock status display can include a first indicator light and a second indicator light. Activating the switch can cause the lock status display to indicate a direction of a most recent rotation of the rotatable portion and/or a locked or unlocked status of the associated door lock.

  • Patent number: 7805969
    Abstract: A multiple dial lock includes reset dials rotatable around a lock shaft. Each reset dial must be at a specific angular position for a user to unlock the lock or reset the combination. Each reset dial has a magnet. A master key includes sensors, each in communication with one signal. Each of the signals indicates to a user that a respective magnet is adjacent a respective sensor, thus assisting a user in recovering a lost combination. A rotary lock includes a dial which rotates a drive cam, which in turn rotates several wheels to their unlocking positions. One magnet for each wheel is provided on the drive cam. Each magnet communicates with one sensor provided on a master key, which also includes signals, indicating that a respective magnet is adjacent a respective sensor, thus assisting a user in recovering a lost combination.

  • Patent number: 7770421
    Abstract: A padlock comprising a housing, a shackle, a lock mechanism and a movable block. The shackle is mounted on the housing and has a first end formed with a shaft portion movably mounted in the housing, and a second end formed with a locking portion moved with the shaft portion and extended outward from the housing. The lock mechanism is mounted on the housing, and includes a lock core and a limit knob. The lock core is mounted in the housing, and the limit knob is located outside the housing and movable by the lock core so as to engage or disengage with the locking portion of the shackle. The movable block is connected to the limit knob of the lock mechanism so that the movable block can be moved to an indication position by operating the lock core of the lock mechanism.

  • Patent number: 7765840
    Abstract: By providing a single housing and shackle assembly constructed for enabling the shackle to be opened and/or closed using either a rotatable dial combination construction or a key activating tumbler construction, with the movement of the shackle being controlled by a trigger member, an effective, easily produced, padlock is achieved which incorporates two separate and independent locking systems formed in a single padlock. In addition, the trigger member and shackle each incorporate uniquely constructed, cooperating surfaces, each of which comprise a grooved zone or concave curved zone which is positioned directly adjacent a cooperating convexly curved zone. By employing these two curved surfaces on both the shackle and trigger member, the controlled pivotal movement of the shackle is realized.

  • Patent number: 7647797
    Abstract: A programmable electronic lock with a closing tongue is actuated with an actuating mechanism formed by a mobile knob acting as a button joined to the closing tongue. Actuation of the mobile knob generates a movement of the closing tongue and closure of the lock. Recovery of the mobile knob to its initial position generates an opening of the lock. Furthermore, an electronics board is activated with a transponder key and controls operation of the lock by deactivating and subsequently activating a blocking mechanism formed by a motor that actuates a punch via a gear mechanism. When the punch is in a blocking position it is located against the actuating mechanism. When the punch is in an unblocking position, it is separated from the actuating mechanism and allows the movement of the closing tongue by unblocking the actuating mechanism.
