Skate blade locking mechanism

Abstract

A skate having a locking mechanism for attaching a blade to front and rear pedestals of a support housing incorporated into a boot. The blade has forward and rear projecting lock arm portions which seat within mating recesses configured within each of the front and rear pedestals of the skate blade housing. A cam lock subassembly is incorporated into an interior of either of the front or rear pedestals in communication with its mating recess and includes a cam locking surface which is biased to seat against a blade locking surface of rear projecting lock arm portion. A cam lock release button projects from the pedestal which, upon depressing, unseats the cam locking surface from the blade locking surface to facilitate downward motion of the skate blade, with successive unseating of the forward lock arm portion detaching the skate blade from the housing.

The skate according to  claim 4 , further comprising the inner body of the cam lock subassembly having a lowermost cam lock pivot feature seated within a circular pocket shaped surface defining in part the interior and integrating a reverse angled cam lock leaf spring seated against a communicating rear support surface of the selected pedestal for biasing the cam locking surface against the blade locking surface. 
     
     
         6 . The skate according to  claim 5 , further comprising a collapsible slot configured in the lowermost cam lock pivot feature for facilitating pinching of split sections of said pivot feature for seating within said circular pocket shaped surface. 
     
     
         7 . The skate according to  claim 2 , said rear lock arm portion further comprising a base and an angled outer leg defining the blade locking surface. 
     
     
         8 . The skate according to  claim 1 , further comprising said support housing being constructed of a casted or injection molded material including at least one of a metal or polymer. 
     
     
         9 . The skate according to  claim 1 , further comprising said cam lock subassembly being constructed of a stamped, metal casted, or injection molded material not limited to a semi-rigid polymer or spring steel. 
     
     
         10 . A skate having a locking mechanism for attaching a blade to front and rear pedestals of a support housing incorporated into a boot, comprising:
 the blade having forward and rear projecting lock arm portions which seat within mating recesses configured within each of the front and rear pedestals of the skate blade housing; and   a cam lock subassembly incorporated into an interior of rear pedestal in communication with the mating recess;   a cam lock subassembly including a cam locking surface which is biased to seat against a blade locking surface of the rear lock arm portion seated within the selected pedestal; and   said cam lock subassembly further including a cam lock release button projecting from the rear pedestal which, upon depressing, unseating the cam locking surface from the blade locking surface to facilitate downward motion of the skate blade, with successive unseating of the other selected lock arm portion from the other selected pedestal detaching the skate blade from the housing.   
     
     
         11 . The skate according to  claim 10 , further comprising each of said forward and rear lock arm portions extending in opposite upward angled directions, said mating recesses extending in downwardly and inwardly angled directions. 
     
     
         12 . The skate according to  claim 10 , the cam lock subassembly further comprising an actuation arm extending from the cam lock release button and communicating with a cam lock release arm incorporated into an inner body of the cam lock subassembly defining the cam locking surface. 
     
     
         13 . The skate according to  claim 12 , further comprising the inner body of the cam lock subassembly having a lowermost cam lock pivot feature seated within a circular pocket shaped surface defining in part the interior and integrating a reverse angled cam lock leaf spring seated against a communicating rear support surface of the selected pedestal for biasing the cam locking surface against the blade locking surface. 
     
     
         14 . The skate according to  claim 13 , further comprising a collapsible slot configured in the lowermost cam lock pivot feature for facilitating pinching of split sections of said pivot feature for seating within said circular pocket shaped surface. 
     
     
         15 . The skate according to  claim 13 , said rear lock arm portion further comprising a base and an angled outer leg defining the blade locking surface. 
     
     
         16 . The skate according to  claim 10 , further comprising said support housing being constructed of a casted or injection molded material including at least one of a metal or polymer. 
     
     
         17 . The skate according to  claim 10 , further comprising said cam lock subassembly being constructed of a stamped, metal casted, or injection molded material not limited to a semi-rigid polymer or spring steel.
