Safety mounting device

Claim 1

A safety mounting device comprising a housing having a longitudinal axis; a first movable member mounted within said housing for sliding movement along said longitudinal axis; a second movable member mounted within said housing between said first movable member and a stop member, said second movable member being mounted within said housing for sliding movement along said longitudinal axis, for rotation about said longitudinal axis and for tilting movement with respect to said longitudinal axis; biasing means for biasing said first movable member against said second movable member to sandwich said second movable member between said first movable member and a stop member; and switch means having an on position and an off position and operable by said first movable member, in one position of said first movable member along said longitudinal axis said switch means being in one of its two positions, in other positions of said first movable member along said longitudinal axis said switch means being in the other of its two positions; said first and second movable members contacting each other by means of a cam surface and a cam follower surface such that rotation of said second movable member about said longitudinal axis from a home position wherein said first movable member is in its said one position displaces said first movable member by cam surface-cam follower action to said other positions thereof, said first movable member also being movable from said one position thereof to said other positions thereof by virtue of movement of said second movable member along said longitudinal axis toward said first movable member and by virtue of tilting of said second movable member relative to said longitudinal axis.
