Skate with length adjustment mechanism

Abstract

A skate comprises a sole plate including an elongate groove through either downward extended wall, and a boot assembly including a heel portion and a toe portion including a rear elongate slot on either side, two fasteners inserted through heel portion and slots for coupling toe and heel portions together and for permitting slots to slide about fasteners within a distance defined by a length of slot, two opposite elongate projections on a bottom each having a length equal to that of slot, a fastening member for securing toe portion and sole plate, and a lever hinged to fastening device. Lever is outwardly pivoted to unfasten fastening member prior to pulling toe portion, and in response slots slide the same about fasteners, thereby moving toe portion relative to sole plate for adjusting the skate length.

What is claimed is:  
     
         1 . A skate comprising: 
 a sole plate including two opposite walls downward extended from front sides and an elongate groove through either wall; and    a boot assembly including a heel portion having a hole on either side and a toe portion including a rear elongate slot on either side, two fasteners inserted through the holes and the slots for coupling the toe portion and the heel portion together and for permitting the slots to slide about the fasteners within a distance defined by a length of the slot, two opposite elongate projections on a bottom each having a length equal to that of the slot, two transverse apertures through the projections, a fastening member driven through the apertures and the grooves and secured to one of the projections, and a lever hinged to the fastening device;    wherein in an adjustment of a length of the skate, the lever is outwardly pivoted to unfasten the fastening member prior to pulling the toe portion either forward or rearward, in response the slots slide either forward or rearward about the fasteners, thereby moving the toe portion with respect to the sole plate, and fasten the fastening member by inwardly pivoting the lever until being stopped the other projection.    
     
     
         2 . The skate of  claim 1 , wherein the skate is mounted with a plurality of wheels.  
     
     
         3 . The skate of  claim 2 , wherein the wheels are tandem.  
     
     
         4 . The skate of  claim 1 , further comprising a tendon guard having two lower side holes with the fasteners secured therein.  
     
     
         5 . The skate of  claim 1 , further comprising an open channel on an outer side of the other projection and a stop in the channel for fastening the lever when the lever is urged against the other projection.  
     
     
         6 . The skate of  claim 1 , further comprising a nut-like member having a peripheral flange for securing the fastening member to one projection.  
     
     
         7 . The skate of  claim 1 , wherein the sole plate further comprises a first toothed section on either wall and the toe portion further comprises a second toothed section on either projection meshed with the first toothed section.
