ELECTRICALLY OPERATED LOCK

摘要

An electrically operated lock comprising a housing (50), a mechanical member (55) supported adjacent to said housing (50) and movable relative thereto, a locking member (72; 218) movable into and out of an operative position in which it engages with the mechanical member (55) to prevent the movement of said mechanical member as aforesaid, and an electrically actuated mechanism (70; 210) for moving the locking member (72; 218) into and out of its operative position. More particularly, the system comprises a magnet (213) supported within said housing, an electrical coil (214) supported for movement within the field of said magnet (213), a first spring (215) mechanically coupled to said coil for movement therewith between two stable positions, and a second spring (217) coupled to said first spring for movement therewith and coupled to the locking member (72; 218) to move the locking member into and out of its operative position in engagement with said mechanical member (55) as said first spring moves between its two stable positions.
