A security apparatus for attaching a portable unit to be protected to a supporting surface. The security apparatus includes a normally deactivated passive locking unit, which is activated by an electronic key unit, which is portable and moved adjacent to the passive locking unit to power it. The key unit includes a device for coupling electromagnetically the key and the locking units to transmit electrical power therebetween. A magnet is concealed within the security device to activate the electronic key, only when it is placed in the proper position relative thereto. Additionally, a mechanical arrangement for a locking pin is employed to further provide a level of sophistication before the actual unlocking of the device occurs.

A security apparatus for attaching a unit to be protected to a supporting surface, comprising: frame means including an upstanding pivot leg and an upstanding housing leg for securing the unit to the supporting surface, said frame means having elongated openable means for permitting the unit to be received therein or removed therefrom by an authorized user; said openable means including a bar having a locking end securable to said housing leg and a pivoting end pivotally mounted to said pivot leg of said frame means for surrounding a portion of the unit, wherein said bar is pivoted to an opened position for receiving or removing the unit into or out of said frame means and to a closed position for securing the unit within said frame means; said openable means further including a mounting pin, having a top portion, said pin being disposed near said bar pivoting end to facilitate pivotal movement of said bar about said pivot leg; locking means for securing said bar in said closed position to help prevent the unit from being removed from said frame means by an unauthorized user; said locking means including a removable locking pin, having a locking pin imperforate top portion and a lower shaft portion, said shaft portion being held releasably to prevent pivotal motion of said bar; said locking pin imperforate top portion being complementary shaped and substantially similar in appearance to said mounting pin top portion to conceal the true function of said locking pin for security purposes; said imperforate top portion further helping to prevent a tool from withdrawing said locking pin from said recess opening in said locking end of said locking bar when said locking pin is held releasably within said recess opening; said locking means further including pin retaining means for securing releasably said shaft within said locking means to hold said bar in said closed position; said upstanding housing leg having a cavity therein for confining and concealing substantially said locking means from view and for receiving said shaft portion of said locking pin to permit only the top portion thereof to be exposed to view so that an unauthorized person would not be aware that the locking pin can be removed to unlock said openable means; means for controlling said retaining means to free said shaft therefrom for permitting the removal of said shaft from said cavity and the pivoting of said bar to said opened position; said locking bar having means defining an opening for receiving completely said top portion of said locking pin to prevent said locking pin from being removed from the opening when the locking pin is retained in a locked position by said pin retaining means; said locking bar further having means defining a small smooth shaft receiving opening in communication with said top receiving recess opening to receive said lower shaft portion of said locking pin to enable said shaft portion to extend into said cavity; and means for urging said locking pin axially outwardly out of said cavity to back said locking pin at least partially out of said upper recess opening in said bar to permit said locking pin to be completely withdrawn from said cavity manually by an authorized user without the aid of a tool, to free said locking bar to permit said locking pin to be moved pivotally about said pivoting end.
