Double locking snap hook

A snap hook, comprising:

• a base including a handle portion and a hock portion;
• a bolt having a longitudinal axis and movably mounted within a first opening in said handle portion;
• a first spring, interconnected between said bolt and said handle portion, and operable to urge said bolt axially along said first opening, outward from said handle portion, across a gap defined by said hook portion, and into an aligned opening in a far end of said hook portion;
• a latch movably mounted to said handle portion, wherein said latch includes a pin which extends transverse to said longitudinal axis and is movable along a second opening in said handle portion, wherein said second opening extends generally transversely into said first opening, and said pin is movable across a juncture defined between said first opening and said second opening;
• and
• a second spring, interconnected between said latch and said handle portion, and operable to urge said pin along said second opening, through the juncture, and into a notch in said bolt when said bolt occupies said aligned opening in said far end of said hook portion, whereby a user must overcome forces exerted by said second spring and said first spring in order to remove said bolt from said far end of said hook.

A snap hook, comprising:

• a base including a handle portion and a hook portion;
• a bolt having a longitudinal axis and movably mounted within a first opening in said handle portion;
• a first means, mounted on said base, for biasing said bolt toward a closed position relative to said hook portion;
• a second means, mounted on said base, for selectively preventing movement of said bolt out of said closed position, wherein said second means includes a pin mounted within a second opening in said handle portion and movable between a first position, outside both said first opening and a notch in said bolt, and a second position, inside both said first opening and said notch in said bolt.

A snap hook, comprising:

• a base including a handle portion and a hook portion, wherein a T-shaped opening in the handle portion includes aligned first and second segments and an orthogonal third segment;
• a bolt having a longitudinal axis and movably mounted within said first and second segments;
• a first means, mounted on said base, for biasing said bolt toward a closed position relative to said hook portion, wherein said first means includes a helical coil spring disposed inside one of said first and second segments and compressed between said handle portion and said bolt;
• and
• a second means, mounted on said base, for selectively preventing movement of said bolt out of said closed position, wherein said second means includes a pin mounted inside said third segment and movable along said third segment and into engagement with a notch in said bolt.

A snap hook, comprising:

• a bolt having a longitudinal axis and movably mounted to said handle portion;
• a first spring, interconnected between said bolt and said handle portion, and operable to urge said bolt axially outward from said handle portion, across a gap defined by said hook portion, and into an opening in a far end of said hook portion;
• a latch movably mounted to said handle portion, wherein said latch has side walls disposed outside opposite sides of said handle portion and a pin interconnected between said side walls;
• and
• a second spring, disposed between said side walls on said latch, interconnected between said latch and said handle portion, and operable to urge said pin into engagement with said bolt when said bolt occupies said opening in said far end of said hook portion, whereby a user must overcome forces exerted by said second spring and said first spring in order to remove said bolt from said far end of said hook.
