Claims24
An apparatus lockable by a locking device having a lock head selectively changeable between an unlocked first orientation and a locked second orientation, the apparatus comprising:
- a housing having an access door permitting access to a removable component located within an interior of the housing, the access door movable between a closed position and an open position;
- a slot extending through the housing, the slot sized and located to receive the lock head of the locking device when the lock head exhibits the first orientation and to retain the lock head when the lock head exhibits the second orientation;
- and
- a latch assembly disposed in the housing and spring biased to maintain the access door in the closed position when the lock head exhibits the second orientation and is positioned within the slot, and to permit the access door to be opened when the lock head exhibits the first orientation and is positioned within the slot.
An apparatus lockable by a removable locking device having a lock head selectively changeable between an unlocked first orientation and a locked second orientation, the apparatus comprising:
- a housing including an access door permitting access to a removable component located substantially within a cavity interior to the housing, the access door movable between a closed position and an open position;
- a slot extending through the housing, the slot sized and located to receive the lock head of the removable locking device when the lock head exhibits the first orientation and to retain the lock head when the lock head exhibits the second orientation;
- a latch spring biased to a first position to engage the access door and maintain the access door in the closed position when the lock head exhibits the second orientation, the latch movable to a second position that permits the access door to be opened when the lock head exhibits the first orientation;
- and
- a stop element disposed on the latch, the stop element to engage the lock head and to maintain the latch in the first position when the lock head exhibits the second orientation, and to allow the latch to be moved to the second position when the lock head is positioned in the slot and exhibits the first orientation.
A projector lockable by a locking device having a lock head selectively changeable between an unlocked first orientation and a locked second orientation, the projector comprising:
- a housing including an access door situated on a first side of the housing permitting access to an interior of the housing, the access door movable between a closed position and an open position;
- a lamp assembly disposed within the housing adjacent the access door;
- a slot extending through a second side of the housing, the slot sized and located to receive the lock head of the locking device when the lock head exhibits the first orientation and to retain the lock head when the lock head exhibits the second orientation;
- a latch spring biased to a first position to engage the access door and maintain the access door in the closed position when the lock head exhibits the second orientation, the latch movable along the second side of the housing to a second position that permits the access door to be opened when the lock head exhibits the first orientation;
- and
- a stop element disposed on the latch, the stop element to engage the lock head and to maintain the latch in the first position when the lock head exhibits the second orientation.
A projector lockable by a removable locking device having a lock head selectively changeable between an unlocked position and a locked position, the projector comprising:
- a housing including an interior and an access feature providing access to the interior;
- an opening extending through the housing, the opening being configured to receive the lock head of the removable locking device when the lock head is in the unlocked position, and to retain the lock head when the lock head is in the locked position;
- a latch assembly movably coupled to the interior of the housing, wherein the latch assembly includes a retaining element that is spring biased to a latched position to be joined with a complementary retaining element on the access feature when the lock head is in the locked position, and to be disengaged from the complementary retaining element on the access feature when the latch assembly is in an unlatched position, and wherein the latch assembly is movable from the latched position to the unlatched position when the lock head is disposed within the opening and positioned in the unlocked position.
An apparatus lockable by a locking device having a lock head selectively changeable between an unlocked first orientation and a locked second orientation, the apparatus comprising:
- a housing having an access door permitting access to a cavity within the housing;
- a lens assembly substantially disposed within the housing;
- a lamp assembly substantially disposed within the housing, wherein the access door permits access to the lamp assembly within the housing;
- a slot extending through the housing, the slot sized and located to receive the lock head of the locking device and to retain the lock head when the lock head exhibits the locked orientation;
- and
- a latch assembly disposed in the housing and spring biased to maintain the access door in a closed position when the lock head exhibits the locked second orientation and is positioned within the slot, and to permit the access door to be opened when the lock head exhibits the first orientation and is positioned within the slot.
