Abstract: A status indicator for a locking mechanism may include a status indicator face, a status indicator plate, a cam coupling, and a locking mechanism coupler. The status indicator face and status indicator plate may be at least partially moveable relative to one another. The locking mechanism coupler may have a greater rotational range of motion than the cam coupling. The status indicator face may indicate the state of a locking mechanism and may have a viewing angle greater than or equal to 180 degrees.

Abstract: An indicator lock has a rotatable indicator which rotates with the depression of a button on the other side of the lock which is used to simultaneously cause a door to be locked and rotate the indicator. This is accomplished by way of a shaft which rotationally moves with the the locking button. The locking button is pressed inwards and rotates as it is pressed inwards due to a channel which is diagonally disposed relative to the direction the button is pressed. A pin extending out from a shaft of the button is in the diagonal channel and a spring adds tension to push the button and display back to the unlocked configuration. This tension is overcome when the button is pressed and the pin enters into a section of the channel which is parallel to the shaft and direction of button press.

Abstract: A door latch assembly configured to be used in an aircraft lavatory door. The door latch assembly includes a housing that includes a housing interior, a switch member operatively associated with the housing that is rotatable between a first position and a second position, and a locking bolt that is movable linearly between an unlocked position and a locked position. Rotation of the switch member from the first position to the second position moves the locking bolt from the unlocked position to the locked position.

Abstract: A latch mechanism is provided that includes a housing, a cap, and at least one indicator. The cap may include a central axis and may be mounted for selective rotational movement relative to the housing about the central axis between a latched position and an unlatched position. The at least one indicator may be interposed between the cap and the housing, such that the cap is in covering relationship to at least a portion of the at least one indicator. The at least one indicator may also be mounted for radial movement outwardly from the central axis relative to the cap as the cap is rotated from the latched position to the unlatched position such that the cap is no longer in covering relationship to the portion of the at least one indicator.

Abstract: A latch includes a first locking bolt, where a first extended position of the first locking bolt defines a first locked condition and a first retracted position defines a first unlocked condition. The latch also includes a second locking bolt, where a second extended position of the second locking bolt defines a second locked condition and a second retracted position defines a second unlocked condition. A biasing member operatively connects to the first locking bolt to bias the first locking bolt in the first extended position. A lever pivotally connects to the housing and operatively connects to the first locking bolt such that movement of the lever from a closed position to an opened position causes at least the first locking bolt to move from the first extended position to the first retracted position. A locking indicator is provided in associated with the second locking bolt.

Abstract: An exit device having a dogging mechanism assembly for providing a visual indication of the state or position of at least certain components of the exit device, such as, for example, a latch, drive rod, and/or a hook bracket. The dogging mechanism assembly includes a displaceable arm actuator mechanism that is coupled to the hook bracket, the hook bracket being adapted to lockingly engage the drive rod. The actuator arm mechanism is adapted to displace an indicator mechanism at least from a first indicator position to a second indicator position as the actuator arm mechanism is displaced to at least one of a first position and a second position. The indicator mechanism has one or more indicators that provide a visual indication of a state or position of a component of the exit device when the indicator mechanism is in at least one of a first and second indicator position.

Abstract: An apparatus for a cylindrical deadbolt assembly indicates whether the deadbolt is locked or unlocked. The apparatus comprises a trim piece, such as an escutcheon or collar, configured to be mounted on the inside face of a door, a dial mounted on an inside surface of the trim piece, and a cam. The trim piece comprises one or more windows for displaying information from the dial. The dial is operative to travel between first and second positions to provide a first indication when the deadbolt is locked and a second indication when the deadbolt is unlocked. The cylinder tail piece turns the cam to move the dial between its first and second positions.

Abstract: A handle assembly and related methods for actuating a mechanism such as a disconnect switch.

Abstract: A stall structure includes a door mounted between two pilasters. The stall also includes an occupancy indicator. The occupancy indicator is engaged by the action of closing the door so that the occupancy indicator changes from indicating the stall as vacant to indicating the stall as occupied. The indicator may include a display having a VACANT indicator and an OCCUPIED indicator. An engagement element may engage the stall structure as the door is closed and move the display from the VACANT indicating position to the OCCUPIED indicating position.

Abstract: A lock assembly is disclosed that is operable to mechanically lock a moveable structure to a fixed structure. An escutcheon assembly having an indicator plate movable between a first position and a second position is operable to indicate a locked and unlocked configuration respectively of the lock assembly. A status indicator located proximate a front face and a pair of opposing side faces on the indicator plate to indicate a locked or unlocked status is visible across a 180 degree viewing angle.

Abstract: A communication system including a fluid-operated calling device mounted in a first location in a building, and a fluid-operated indicator mounted in a second location in a building and in fluid communication with the fluid-operated calling device, wherein actuation of the fluid-operated calling device causes the fluid-operated indicator to provide an indication that the fluid-operated calling device has been actuated. A fluid-operated lock may be mounted near the fluid-operated calling device and in fluid communication with a fluid-operated actuator, wherein actuation of the fluid-operated actuator causes opening of the fluid-operated lock.

Abstract: An apparatus for automatically opening a swinging restroom door is provided. The apparatus comprises an actuator, a control unit, and a power assisted drive mechanism that can be connected to an existing door closing mechanism. The actuator comprises a proximity sensor and further comprises a series of iconic symbols corresponding to predetermined proximity zones. The control unit is in electronic communication with the actuator with which signals are exchanged. The power assisted drive mechanism is in electronic communication with the control unit and can be connected to an existing door closing mechanism wherein the actions of the door closing mechanism are reversed and the door is opened.

Abstract: An electric sign is arranged to afford a readily observable visual indication of the condition of an establishment such as a retail establishment having an entrance door provided with a lock and wherein the sign includes a visual device for indicating a condition of the establishment such as "closed" or "open" together with a switch for energizing the visual device, and a control mechanism actuated in coordination with locking and unlocking of the establishment door for selectively controlling the control mechanism for energizing the visual device.

Abstract: An improved price display system for a multi-level merchandising machine in which the prices of articles at the respective levels are electronically displayed individually at locations immediately adjacent to the levels. Both the prices and the displays can be changed in a rapid and expeditious manner from a station within the machine cabinet. In addition, both the mode of operation and the compartment size of a level can be displayed and changed. The system may be provided with a timer for automatically changing all prices at a predetermined time. The system employs a small number of conductors to control a large number of displays.
