Abstract:
1. A magnetic coupling apparatus comprising: at least one shaft member of circular cross section, the shaft member defining a base and a tip at opposite ends thereof, an entire length of said shaft member defined between said ends, and at least one recess circumferentially encircling a portion of said shaft member; a lock housing defining an opening extending through opposite sides of said housing, a bore extending perpendicular to, and in communication with, said opening, said opening adapted for receiving said entire length of said shaft member; an interengagement member carried within said bore and adapted for slideably engaging with said at least one recess, a magnetic key slideably engagable with said lock housing to encircle an external portion of said lock housing, said interengagement member responsive to a magnetic force applied by said key effecting the interengagement member to move from an engaged position to a disengaged position; whereby when said interengagement member is in said engaged position, said interengagement member is slidingly engaged in said recess, locking said shaft member to prevent removal of said shaft member from said housing while allowing said shaft member to rotate with respect to said housing, and whereby when said interengagement member is in said disengaged position, said interengagement member is removed from said recess allowing removal of said shaft member from said housing in an axial direction of said shaft member.
