ABSTRACT:
Apparatus is described for climbing a sailboat mast or other vertical structure. The apparatus includes a track which extends upward along the mast and a pair of climbing devices which are usable by an operator to raise himself up along the track. Each of the climbing devices includes a carriage which is mounted on the track for sliding movement therealong and a lever bar pivotally mounted to the carriage for locking the device at any selected location along the track. The locking action is obtained by the application of downward force on the locking lever causing an end of the same to frictionally engage the track. One of the locking levers is adapted to receive the feet of an operator, whereas the other is adapted for hand grasping. The apparatus is used by the operator engaging his feet and hands with the foot and hand devices respectively and then climbing the mast by alternately sliding the foot and hand devices upward along the track.
