185 words
A quick fastener for a roller skate comprising: a band adapted to be affixed to the roller skate; said band being provided on one face with transverse saw-teeth; a substantially U-shaped rigid support member adapted to be affixed to one side of the roller skate in operative relationship relative to the band; and a spring pawl being outwardly exposed and operatively affixed to the substantially U-shaped support and including an active end biased toward the substantially U-shaped support for engaging the transverse saw-teeth of said band; said spring pawl further including a knurled part displaceable relative to said active part and being manually engageable for displacing said active part away from said substantially U-shaped support; wherein when said band is disposed between the substantially U-shaped support and the spring pawl said active end automatically engages the transverse saw-teeth and said band is lockingly engaged relative to said U-shaped support and upon manually biasing said active end of said spring pawl away from said substantially U-shaped support said active end disengages from said band to permit the release of said band from said substantially U-shaped support.
Claim 2
