Magnetic switch with auto-release function
First Claim
1. A magnetic switch installed in hinged first member and second member of a lifting cover type article for locking the hinged first member and second member when the hinged first member and second member are closed together, the magnetic switch comprising:
- a fixed unit fixedly mounted in a front end edge of the second member of said lifting cover type article, said fixed unit comprising at least one magnetic device;
a movable unit mounted in a front end edge of the first member of said lifting cover type article;
said movable unit comprising a driven rod arranged in parallel and movable relative to the front end edge of the first member of said lifting cover type article, a holder member fixedly mounted on said driven rod movable with said driven rod relative to the first member of said lifting cover type article between a first position and a second position, at least one magnetic device mounted in said holder member and adapted to attract the at least one magnetic device of said fixed unit when said holder member is in said first position and to repulse the at least one magnetic device of said fixed unit when said holder member is in said second position, spring means mounted on said driven rod and connected between a part of said driven rod and a part of the first member of said lifting cover type article to support said holder member in said first position, and a key extending out of the front end edge of the first member of said lifting cover type article for operation by the user to move said driven rod relative to the front end edge of the first member of said lifting cover type article against the spring power of said spring means and to further move said holder member from said first position to said second position.

Abstract
A magnetic switch is disclosed to include a first magnetic device affixed to a second member of a lifting cover type of a article, a driven rod slidably mounted in a first member of the lifting cover type of the article that is hinged to the second member, a holder member mounted on the driven rod and holding a second magnetic device for attracting the first magnetic device to keep the fist member and the second member in the closed position, a spring member that imparts a pressure to the driven rod to hold the holder member in such a position that the second magnetic device attracts the first magnetic device, and a key extending out of the first member of the lifting cover type of the article for operation by hand to move the driven rod to the position where the second magnetic device repulses the first magnetic device to force the second member away from the first member.

1. A magnetic switch installed in hinged first member and second member of a lifting cover type article for locking the hinged first member and second member when the hinged first member and second member are closed together, the magnetic switch comprising:
-
a fixed unit fixedly mounted in a front end edge of the second member of said lifting cover type article, said fixed unit comprising at least one magnetic device; a movable unit mounted in a front end edge of the first member of said lifting cover type article;
said movable unit comprising a driven rod arranged in parallel and movable relative to the front end edge of the first member of said lifting cover type article, a holder member fixedly mounted on said driven rod movable with said driven rod relative to the first member of said lifting cover type article between a first position and a second position, at least one magnetic device mounted in said holder member and adapted to attract the at least one magnetic device of said fixed unit when said holder member is in said first position and to repulse the at least one magnetic device of said fixed unit when said holder member is in said second position, spring means mounted on said driven rod and connected between a part of said driven rod and a part of the first member of said lifting cover type article to support said holder member in said first position, and a key extending out of the front end edge of the first member of said lifting cover type article for operation by the user to move said driven rod relative to the front end edge of the first member of said lifting cover type article against the spring power of said spring means and to further move said holder member from said first position to said second position. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A magnetic switch installed in hinged first member and second member of a lifting cover type article for locking the hinged first member and second member when the hinged first member and second member are closed together, the magnetic switch comprising:
-
a fixed unit fixedly mounted in a front end edge of the second member of said lifting cover type article, said fixed unit comprising at least one magnetic device; a movable unit mounted in a front end edge of the first member of said lifting cover type article;
said movable unit comprising a driven rod arranged in parallel and movable relative to the front end edge of the first member of said lifting cover type article, a holder member pivoted to the first member of said lifting cover type article and rotatable by said driven rod through 180°
between a first position and a second position when said driven rod is moved relative to the first member of said lifting cover type article, a magnetic device mounted in said holder member and adapted to attract the at least one magnetic device of said fixed unit when said holder member is in said first position and to repulse the at least one magnetic device of said fixed unit when said holder member is in said second position, spring means mounted on said driven rod and connected between a part of said driven rod and a part of the first member of said lifting cover type article to support said driven rod in the position where said holder member is in said first position, and a key extending out of the front end edge of the first member of said lifting cover type article for operation by the user to move said driven rod relative to the front end edge of the first member of said lifting cover type article against the spring power of said spring means and to further move said holder member from said first position to said second position. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
