Protective device for instruments and locking of aircraft controls

DETAILED DESCRIPTION It is a primary object of the invention to provide a single device which both locks the aircraft controls and prevents theft of the aircraft instruments, thus solving the problems outlined above and overcoming the defects and disadvantages of the prior art devices.
It is another important object of the invention to provide a protective device which is of simple construction, easy and inexpensive to fabricate, easy to install and is readily removable.
Yet another important object of the invention is to provide a protective device, having the above described characteristics, which include a cover plate for mounting directly adjacent and in front of the instrument panel, said cover plate having mounting and locking means which cooperate with the control column of the aircraft and which clamp the control column against movements which would permit unauthorized takeoff and flight.
These and other objects of the invention are achieved in a preferred embodiment by provision of a generally flat plate which is positioned immediately adjacent and in front of the aircraft instrument panel, and locked in such position by a pair of complementary clamping blocks which grip the control column of the aircraft and are secured by a padlock, at least one of the blocks being rigidly affixed to the cover plate.
The invention will be better understood and objects other than those set forth above will become apparent from reading the following detailed description thereof.
Such description presenting a preferred embodiment of the invention which is illustrated in the annexed drawings.
