Abstract
A spring loaded rope winder having a centrifugal brake mechanism incorporated in the reel of the rope winder with the effect of slowing the winding-up of rope onto the reel.
Claims5
A pet rope winder comprising:
- a case;
- a reel rotatably accommodated in said case and supported by a shaft provided in said case, said reel comprising a basic body having peripheral edges and first and second flanges provided on said peripheral edges of said basic body, said flanges extending radially from said basic body;
- a spring energizing said reel in a rope windup direction;
- a brake piece radially and slidingly positioned on an external face of at least one of said first and second flanges of said reel, whereby said brake piece slides outward from said basic body upon application of a centrifugal force effected when a rope is wound up and whereby said brake piece slidingly contacts an internal peripheral wall of said case, said internal peripheral wall being substantially parallel to said shaft of said case;
- and
- means for holding said brake piece, said holding means positioned on an external face of said flange and comprising a surrounding wall forming a pocket section having an opening opposite the internal peripheral wall of the case for slidingly accommodating the brake piece.

- a spring energizing said reel in a rope windup direction;
- a brake piece radially and slidingly positioned on an external face of at least on of said first and second flanges of said reel, whereby said brake piece slides outward from said basic body upon application of a centrifugal force effected when a rope is wound up and whereby said brake piece slidingly contacts an inner peripheral wall of said case, said inner peripheral wall being substantially parallel to said shaft of said case;
- and
- means for holding said brake piece, said holding means positioned on the external face of the flange and comprising a projection for engagement which engages a groove for engagement provided at a substantially central position of the brake piece and slidingly holds the brake piece and ribs which are positioned on the external face of said flange on both sides of the brake piece and guides sliding movement of the brake piece.
