Abstract:
A gun lock comprising:a housing dimensioned and configured to releasibly engage a trigger guard of a gun, the housing having a trigger jam window, at least one thumb wheel window, and at least one notch defined therein; a keyed cylinder slidingly disposed within the housing and translatable between a first unlocked position and a second locked position, the keyed cylinder comprising: a push end that extends outward from the notch in the housing; at least one key extending from the keyed cylinder; and at least one extension extending from the keyed cylinder; at least one thumb wheel pin disposed within the housing at a point proximate to the thumb wheel window; at least one thumb wheel having a peripheral edge and a key notch defined therein, wherein the thumb wheel is rotatingly disposed on the thumb wheel pin such that the peripheral edge of the thumb wheel extends through the thumb wheel window, and further wherein the key notch is dimensioned and configured to matingly engage the key of the keyed cylinder when the thumb wheel is rotated to a predetermined position, and; a trigger jam support disposed within the housing at a point proximate to the trigger jam window; a trigger jam assembly comprising: a trigger jam having pivot shaft defined therein, werein the pivot shaft rotatingly engages the trigger jam support such that the trigger jam extends from the trigger jam window and is movable between a first unlocked position wherein the trigger jam is removed from a trigger of the gun, and a second locked position wherein the trigger jam is urged against the trigger of the gun; and wherein the trigger jam has a slotted lock pin cavity defined therein and further comprises a lock pin slidingly disposed within the lock pin cavity, the lock pin being movable between a first unlocked position in which the lock pin will pass freely through the trigger jam window, and a second locked position in which the lock pin abuts the housing at point within the housing and wherein when in the locked position the lock pin arrests movement of the trigger jam from the locked position; wherein when the thumb wheel is rotated to the predetermined position, the key of the keyed cylinder is able to matingly engage the key notch of the thumb wheel such that the keyed cylinder can be translated from the locked position to the unlocked position by pushing or pulling on the push end of the keyed cylinder, and further wherein when the keyed cylinder is translated from the locked position to the unlocked position, the extension extending from the keyed cylinder is urged against the lock pin such that the lock pin is moved from the locked position to the unlocked position, thereby allowing the lock pin to pass through the trigger jam window and the trigger jam to rotate about the pivot shaft from the locked position to the unlocked position.
