Biased cuff assembly

A biased cuff assembly comprising:

• a cuff having a first arcuate section hingedly coupled to a second arcuate section;
• a hinge coupling said first arcuate section to said second arcuate section;
• a slit extending through said first arcuate section, a free end of said second arcuate section being insertable into said slit and engageable to said first arcuate section forming a closed loop configured for securing said cuff to an extremity of a person;
• a sheath pivotally coupled to said first arcuate section of said cuff, said sheath having a longitudinal slot, said first arcuate section of said cuff being positioned in said slot, said sheath having an arcuate edge extending into an opening of said loop when said sheath is in a retracted position wherein said arcuate edge of said sheath is configured to contact the extremity extending through said loop, said sheath being pivotally coupled to said hinge coupling said first arcutate section of said cuff to said second arcuate section of said cuff;
• a biasing member coupled to said first arcuate section of said cuff, said biasing member being positioned to bias said sheath to pivot outwardly away from said opening of said loop, said biasing member being a torsion spring;
• a stopper coupled to and extending from said arcuate edge of said sheath into said opening of said loop wherein said stopper is positioned to abut said first arcuate section of said cuff when said sheath is biased into a fully extended position;
• a locking pin slidably coupled to said first arcuate section of said cuff, said locking pin being slidable between a first position and a second position;
• and
• a curved locking slot extending through said first arcuate section, said locking pin being positioned in said locking slot, said locking slot having a first end section and a second end section, said first end section being laterally offset from said second end section such that said sheath is secured in said fully extended position when said locking pin is positioned in said first end section and said sheath is positioned in a fully retracted position when said locking pin is positioned in said second end section of said slot.
