Device for temporary mechanical attachment of an object to a support and rapid ejection of the object from the support

A mechanism for attaching, separating and ejecting an object having an internal elongated recess therein, said mechanism comprising:

• a receptacle having a longitudinal axis and a reduced body portion along said longitudinal axis at one end of said receptacle, said receptacle further having a male centering segment complementary with said reduced body portion of said receptacle, said male centering segment of said receptacle being mounted for slidable engagement with one end of said internal elongated recess of said object;
• a fragile coupling coaxially disposed with said longitudinal axis and interposed said male centering segment and said object;
• an annular end member having one end attached to said fragile coupling and an external diametral surface;
• means for mounting said external diametral surface to said internal elongated recess of said object;
• and
• an ejector rod slidably mounted to said receptacle in a direction along said longitudinal axis, said ejector rod having one end contiguous said receptacle and an oppositely disposed end extending from said receptacle, said oppositely disposed end of said ejector rod being substantially coaxial with said fragile coupling and said annular end member, said oppositely disposed end of said ejector rod further being mounted for slidable engagement with an oppositely disposed end of said internal elongated recess of said object;
• whereby when said object is mounted to said annular end member said male centering segment and said oppositely disposed end of said ejector rod of said receptacle slidably engage said internal elongated recess of said object to guide said object after said fragile coupling is separated and said object is ejected from said receptacle.
