Today’s invention is a domestic storage/display case for anything which one thinks of as valuable. This would be in the form of a wall safe with the ability to display the contents behind an armoured glass window -when the safe door is opened.
In the event of a fire alarm, or some other reason for a fast evacuation, this unit would seal its door and be expelled, by eg a strong spring, out of the house and through the wall -guided by a rail to which it is secured by a strong cable lock.
Activated by the fire alarm, this allows precious items to be rapidly moved to a place of safety, removing the temptation to save material things instead of getting the hell out.
