  • the heel 4 and the toe 5 of the skate blade holder 3 generally are hollow.
  • a heating arrangement 8 in the form of a resistance heating member 100 is arranged to heat the skate blade 2 such that the heat reduces the coefficient of friction of the blade 2 on an ice surface.
  • the heating arrangement 8 has a heat control circuit board 9 mounted on the top edge of the blade and a battery 14 and battery control circuit board 14A in the hollow heel tower 4 of the holder 3.
  • the circuit has a thermistor 12 which controls the temperature of the blade by controlling current to the resistance heating member 100.
  • the blade temperature is maintained just above freezing at a temperature of the order of 2 to 10 degrees Celsius and preferably of the order of 4 to 6 degrees, in many cases where the player is off the ice for a short break as in regular shifts in a hockey game, the temperature of the box or other rest area is often sufficiently high that the heater is turned off during the break period off the ice and only turns back on when the player or skater is back on the ice for a sufficient period to cool the blade down to the temperature below the set temperature. This ensures that the heater is used only when required on the ice and the battery power is not wasted when the player is off the ice. This arrangement avoids the use of motion sensors or other timing devices to control the heat application.
  • an accelerometer that will detect motion to trigger the heating circuit.
  • the holder 3 defines an elongated bottom section 15 which extends along the full length of the holder and defines along a center thereof a slot 16 for receiving the blade.

  • the holder Between the hollow towers, the holder includes a U-shaped area 17 defining a top edge 18 which is the top edge of the solid part of the body on which the bottom member 15 is formed.
  • the top surface 18 curves upwardly at the forward end to form a wall 21 which is the rear wall of the front tower 5.
  • the top 18 at its rear curves upwardly to form an upward and forwardly extending portion 18B which forms the front wall of the rear tower 4.
  • the front tower 5 thus has a rear end at the rear end of the flange 6 which overlies the surface 18 and symmetrically a forward end of the flange 6A of the tower 4 also overlies the surface 18.
  • the front tower 5 has a front wall 21 which extends downwardly to a forward end 22 of the member 15.
  • the rear tower 4 has a rear wall 23 which extends downwardly to a rear end 24 of the member 15.
  • the wall extending upwardly from the member 15 to the base of the towers includes side ribs which extend upwardly and rearwardly as indicated at 25 and 25A together with downwardly extending ribs 26 which connect from the inclined ribs 25 and 25A to the bottom end 15 to provide an attractive appearance.
  • the member 15 defines a slot 16 in its bottom surface with the slot 16 extending upwardly to an upper end 27 and defining two side walls 28 and 29 of the slot.
  • the slot extends only partly across the width of the member 15 so that two shoulders 30 and 31 are formed at the bottom of the member 15 on either side of the slot 16.
  • This slot provides a receptacle for the blade so that the blade may be inserted into this slot and pulled up into the slot to be held in fixed position on the bottom of the member 15 and held against side to side movement by engagement between the blade and the slot.
  • the blade 2 includes a steel blade portion 32 and an over-molded portion 33 of a plastics material.
  • the over-moulded portion is moulded onto the sides of the steel blade 32 and across the top edge of the steel blade 32 so as to form a structural member rigidly and permanently attached to the steel blade and extending out to each side of the steel blade.
  • the steel blade 32 engages into the over-molded plastics portion 33 so that it is held in place within that plastics portion.
  • the plastics portion 33 includes a projecting element 34 with sides 35 and 36 which engage into the slot 16.
  • the over-molded portion 33 inciudes top shoulders 37 and 38 which engage against the shoulders 30 and 31 of the bottom surface of the member 15.
  • the steel blade 32 includes a top edge 40 which has a complex shape for engagement into the over-molded plastics portion 33.
  • the steel blade 32 has a bottom edge 41 which forms the skate blade edge of a conventional shape with slightly upwardly curved front and rear portions 41 A and 41 B.
  • the complex upper edge 40 of the steel blade portion is shaped to define a series of hooks which engage into the over-molded plastics portion 33 to maintain permanent engagement therewith.
  • a front hook 42 at the forwardmost end of the steel blade and this is received just behind the front edge 43 of the over-molded plastics piece so that it is embedded in the plastics piece and acts to retain the blade within that plastics piece.
  • there is a rear hook 44 which engages into the plastics piece just in front of the rear edge 45 of the over-molded plastics piece.
  • the steel blade further includes upwardly projecting element 46 in the center section under the surface 18 which projects into the area at the heating element 8.

  • the hook member 55 has a rear surface 57 which extends upwardly and rearwardiy so as to butt against a correspondingly inclined surface of the receptacle 56. It will be appreciated therefore that rearward pulling action on the blade member 2 wilt cause the inclined surfaces to pull the blade upwardly into the siot 16 so as to force the shoulders of the blade against the shoulders at the base of the member 15.
  • the rearward pulling action on the blade is provided by a rear mounting member 58 of the blade.
  • the rear mounting member 58 also projects upwardly through the over-molded plastics member 33 to provide an upwardly extending portion above that member.

  • the nut has a cylindrical outer surface which is contained within the cylindrical bearing surface 62 allowing this pivotal action to accommodate slight inaccuracies in the positioning of the blade relative to the holder.
  • the rear wall 23 of the rear tower 4 has a recessed hole 63 for receiving a screw 64.
  • the screw has a head which engages against a base of the recessed hole so that the screw can engage into the nut and by turning the screw the nut is pulled upwardly and rearwardly as the screw head butts against the shoulders on either side of the hole.
  • the turning of the screw 64 acts to pull the blade upwardly and rearwardly along the slot 16 so as to pull the rear part of the blade into the slot and so as to pull the blade rearwardly along the slot to force the front mounting portion 55 into the receptacle 56.
  • the blade can be mounted on the holder by releasing the screw and by removing the projecting portion of the moulded plastics portion 33 from the slot by pulling the blade downwardly.
  • the blade can be reinserted by simply inserting the blade approximately into its required position thus sliding the front member 55 into the receptacle 56 whereupon the screw and be inserted into the nut and the blade pulled up into place both longitudinally and upwardly.
  • the sides of the portion 33 within the slot are slightly tapered and the side walls of the slot itself are slightly tapered so as to provide a friction fit between the plastics parts as the blade is pulled upwardly.
  • the blade is pulled upwardly until the shoulders engage between the shoulders on the side of the plastics portion 33 and the shoulders at the base of the member 15.
  • the bottom edge 41 of the blade curves upwardly and forwardly at the front end 41 A and curves upwardly and rearwardly at the rear end 41 B.
  • the over-molded portion 33 similarly is curved upwardly at the forward end at 33A and is curved upwardly at the rearward end as indicated at 33B.
  • the bottom edge of the member 15 also curves upwardly and forwardly at the forward end indicated at 15A and upwardly and rearwardly at the rearward end indicated at 15B. in this way the blade and the over-moided portion 33 fit effectively into the slot 16 of the member 15 along the full length of the blade.
  • that part of the over-molded portion 33 which projects above the top edge of the blade 40 in the region of the front curved section 33A has the sides of the over-molded portion 33 castellated as indicated at 33C to provide a series of upstanding slots 33D in the sides.
  • the siots 33D are provided in each side of the over-molded portion and extend down to a depth between the slots approximately equal to the width the blade. These slots are thus formed in the plastic part above the top edge of the blade and extend downwardly to the top edge of the blade.
  • These castellated slots have been found to allow the mounting of the blade into the slot 16 in a manner which reduces vibration of the blade during vigorous stopping actions by the skater. They also add to the stiffness of the blade without adding too much weight.
  • the towers 4 and 5 are arranged to extend upwardly to a position to engage the bottom of a conventional skate boot.
