Apparatus for preventing backlash of spool used in baitcasting reel
Disclosed is an apparatus for preventing backlash of a spool used in a baitcasting reel, in which the number of brake shoes can be optionally adjusted. The position of the shoe is selected between protruded guides of a shoe holder so as to apply braking force, so that the backlash of the spool is precisely controlled, without decreasing the carry distance of casting.
1. An apparatus for preventing backlash of a spool used in a baitcasting reel, the apparatus comprising:
a shoe holder including an opening formed at a center of the holder, through which a shaft of the spool passes, at least two pairs of protruded guides formed radially from the opening and having stop bosses symmetrically formed inside the pair of the protruded guides, and a hole formed between the pair of protruded guides;
at least two shoes having a body inserted between the pair of the protruded guides, a stop boss symmetrically formed at both outer surfaces of the body to abut against the stop bosses of the shoe holder, a protruded frictional portion formed at a front of the shoe, a knob formed at a rear of the shoe, and a hole formed at a center of the shoe;
a spring interposed between the hole of the shoe holder and the hole of the shoe to urge the shoe against the spool shaft;
a shoe supporting plate, fixed to the shoe holder by fastening a screw into a hreaded hole of the shoe holder, for preventing components from being released from the shoe holder, and having a hole through which the shaft of the spool passes and at least two rectangular slots through which the knob of the shoe passes; and
a braking ring mounted to an inner body to be contacted with the frictional portion of the shoe protruded from the shoe holder.
2. The apparatus as claimed in claim 1 , wherein the spring comprises a resilient rubber or an inverted U-shaped leaf spring.
3. The apparatus as claimed in claim 1 , wherein the shoe supporting plate is made of a nonmagnetic material.
