Cage in computer equipment for locking peripheral equipment therewithin using hooked lockpins

A cage with a rectangular opening at a surface of a piece of computing equipment;

• said cage for having inserted therewithin a piece of peripheral equipment with a rectangular front plate, with respective first and second sides parallel to each other and perpendicular to said rectangular front plate, and with a first guide rail located along said first side thereof, said first guide rail having a circular hole of a prescribed diameter therethrough along the extent thereof at a first prescribed distance from said rectangular front plate;
• said rectangular opening having a perimeter comprised of a set of equal-length first and second edges oppositely disposed respective to each other and a set of equal-length third and fourth edges oppositely disposed respective to each other, said first and second edges being of sufficient length to admit the first and second sides of said piece of peripheral equipment in respective proximity thereto, said third and fourth edges being of such length that said rectangular front plate fills at least a portion of said rectangular opening between its said first and second edges;
• said cage being of such construction as to permit said piece of peripheral equipment being secured thereto using a first hooked locking pin, said first hooked locking pin having a substantially cylindrical shank portion of a diameter somewhat less than said prescribed diameter and having a hooked portion at substantially a right angle to its said respective shank portion;
• said cage comprising:
• first and second sides of said cage parallel to each other and perpendicular to said surface of said piece of computing equipment at said first and second edges respectively of said rectangular opening in said surface of said piece of computing equipment;
• a first lead rail located along said first side of said cage tier engaging with said first guide rail of said piece of peripheral equipment and extending perpendicularly from said first edge of said rectangular opening in said surface of said piece of computing equipment, said first lead rail having a circular hole of said prescribed diameter therethrough along the extent thereof at substantially said first prescribed distance from said first edge of said rectangular opening;
• a third side of said cage, perpendicular to said first and second sides of said cage, and extending between said first and second sides of said cage, said third side of said cage having a first circular hole of said prescribed diameter therethrough located such that a first perpendicular axis through its center extends through the center of said hole through said first lead rail and defines a first locus for the insertion of said shank portion of said first hooked locking pin;
• and
• a first hooked catch located near said first circular hole of said prescribed diameter through said third side of said cage, said first hooked catch having its hook opening towards said third side of said cage, said first hooked catch thereby being disposed for capturing said hooked portion of said first hooked locking pin when forced thereagainst after said piece of peripheral equipment is inserted into said cage, said shank portion of said first hooked locking pin is inserted through said first hole through said third side of said cage and said holes in said first guide rail and said first lead rail aligned therewith along said first locus, and said hooked portion of said first hooked locking pin is pivoted on said shank portion of said first hooked locking pin so as to engage with said first hooked catch.
