Abstract

A portable gun box for safely storing at least one of a variety of loaded and unloaded firearms. The gun box includes a child-resistant latching mechanism positioned inside the gun box. In turn, the latching mechanism has a slideable first latching arm; a slidable second latching arm adapted to engage and disengage the first latching arm; a catch attached to the second latching arm to engage a hook on the lid of the gun box when the gun box is closed and to disengage that hook when the gun box is open; and a guide bracket attached to the gun box and substantially surrounding the catch to prevent the hook from disengaging the catch unless the first latching arm and the second latching arm are disengaged. The gun box also includes structure positioned outside the gun box, and penetrating to inside the gun box to engage the latching mechanism and allow the latching mechanism to be operated from outside the gun box, and resilient linings for pushing open the lid of the gun box when the latching mechanism is released.

An improved portable gun box for safely sorting at least one of a variety of loaded and unloaded firearms and of the type having a back, a front, first and second sides, a bottom, a plurality of feet outside said gun box on said bottom to support said gun box, a lid hingedly attached to said back for opening and closing said gun box, and a hook affixed to and projecting downward from said lid inside said gun box, wherein the improvement comprises a child-resistant latching mechanism positioned on the inside of said bottom of said gun boxy and including:

a first latching arm slidably engaging said bottom of said gun box, said first latching arm having a projecting end,
a second latching arm slidably engaging said bottom of said gun box, said second latching arm having an end with a notch which engages said projecting end of said first latching arm when said latching mechanism is in a closed position,
a first foot of said plurality of feet projecting into the inside of said gun box through said bottom of said gun box and engaging said first latching arm for transmitting a sliding motion of said first foot to said first latching arm;
a second foot of said plurality of feet projecting into the inside of said gun box through said bottom of said gun box and engaging said second latching arm for transmitting a sliding motion of said second foot to said second latching arm;
a vertical catch attached to said second latching arm and having a slot near its top, said slot engaging said hook projecting downward from said lid of said gun box when said gun box is closed;
and
a U-shaped guide bracket attached to said front of said gun box and substantially surrounding said vertical catch, said guide bracket preventing said hook from disengaging said slot in said vertical catch unless said first latching arm and said second latching arm are disengaged.
