Abstract:
1. A two-part, magnetically-secured climbing or rigging block, comprising: a) a first block having a first body comprising at least a rear surface having a first central opening disposed therein, a left side surface perpendicular to the rear surface and a right side surface substantially parallel to said left side surface; b) a sheave disposed proximate a lower end of said first body, said sheave being rotatably connected to an axle, said axle being disposed between said right side surface and said left side surface and substantially perpendicular thereto; c) a first magnet having a predetermined pole disposed flush with said rear surface and proximate an upper end of said first body; d) a second magnet having a pole opposite said predetermined pole of said first magnet flush with said rear surface and disposed proximate a lower end of first body; e) a first nose cone having a first portion and a second portion adjacent thereto, said nose cone having a major axis, said first portion being disposed within said first body at a upper end thereof, said second portion extending beyond an upper end of said first body with a portion of said second portion facing away from said first body; f) a second block portion having a second body comprising at least a second rear surface having a second central opening disposed therein, said second central opening being smaller than said first central opening, a second left side surface perpendicular to the second rear surface and a second right side surface substantially parallel to said second left side surface; g) a second sheave disposed proximate a lower end of said second body, said second sheave being rotatably connected to a second axle, said second axle being disposed between said second right side surface and said second left side surface and substantially perpendicular thereto; h) a third magnet having a pole opposite said predetermined polarity of said first magnet flush with said second rear surface and proximate an upper end of said second body; i) a fourth magnet having a pole opposite said predetermined pole of said third magnet flush with said second rear surface and disposed proximate a lower end of said second body; j) a second nose cone having a third portion and a fourth portion adjacent thereto, said nose cone having a major axis, said third portion being disposed within said second body at an upper end thereof, said fourth portion extending beyond an upper end of said second body with a portion of said fourth portion facing away from said second body; and k) a sling rope having a first end permanently attached to at least one of said first body and through said first nose cone and a second end permanently attached to at least one of said second body and through said second nose cone.
