Propeller guard

Abstract

A propeller guard including an elongated and flexible foam block that can be folded near its center so as to engage and cover the leading edge, tip, and trailing edge of a propeller blade. A tie is secured to the foam block for selectively holding the foam block in a folded condition upon the propeller blade such that the leading edge, tip, and trailing edge of the propeller blade is retained within a channel in the block. The tie includes a belt with opposed, first and second ends. A ring is secured to the first end of the belt. A first fastening portion is secured to the top of the belt between the first end and the second end. A second fastening portion, adapted to mate with, and releasably adhere to, the first fastening portion, is secured to the top of the belt between the first fastening portion and the second end.

1 . A propeller guard, comprising:
 an elongated and flexible foam block being adapted to fold proximate the center thereof so as to engage and cover the leading edge, tip, and trailing edge of a propeller blade, and said foam block having a channel therein for receiving the leading edge, tip, and trailing edge of the propeller;   a tie being secured to said block for selectively holding said block in a folded condition upon the propeller blade such that the leading edge, tip, and trailing edge of the propeller blade is retained in said channel, said tie including:
 a belt having a first end and a second end opposite said first end; 
 a ring being affixed to said first end of said belt; 
   a first fastening portion being secured to the top of said belt between said first end and said second end; and,   a second fastening portion, adapted to mate with, and releasably adhere to, said first fastening portion, secured to the top of said belt between said first fastening portion and said second end.   
   
   
       2 . A propeller guard, comprising:
 an elongated and flexible foam block being adapted to fold proximate the center thereof so as to engage and cover the leading edge, tip, and trailing edge of a propeller blade, and said foam block including:
 a pair of opposed side walls; and, 
 a crosspiece connecting said side walls together such that a channel is formed between said side walls, said channel being adapted to receive the leading edge, tip, and trailing edge of the propeller, and said crosspiece having opposite ends and a pair of slots, each of said slots passing through a respective one of said opposite ends; and, 
   a tie being secured to said block for selectively holding said block in a folded condition upon the propeller blade such that the leading edge, tip, and trailing edge of the propeller blade is retained in said channel, said tie including:
 a belt extending through said slots in said block, and said belt having a first end and a second end opposite said first end; 
 a ring being affixed to said first end of said belt; 
   a first fastening portion being secured to the top of said belt between said first end and said second end; and,   a second fastening portion, adapted to mate with, and releasably adhere to, said first fastening portion, secured to the top of said belt between said first fastening portion and said second end.   
   
   
       3 . A propeller guard, comprising:
 an elongated and flexible foam block being adapted to fold proximate the center thereof so as to engage and cover the leading edge, tip, and trailing edge of a propeller blade, and said foam block being U-shaped in cross section so as to define an interior channel for receiving the leading edge, tip, and trailing edge of the propeller;   a tie being secured to said foam block for selectively holding said block in a folded condition upon the propeller blade such that the leading edge, tip, and trailing edge of the propeller blade is retained in said channel, said tie including:
 a belt having a first end and a second end opposite said first end; 
 a ring being affixed to said first end of said belt; 
   a first fastening portion being secured to the top of said belt between said first end and said second end, and said first fastening portion having a dense mat of small uncut loops; and,   a second fastening portion being secured to the top of said belt between said first fastening portion and said second end, and said second fastening portion having a plurality of hooks being releasably fastenable with said loops of said first fastening portion.
