Definitions

  • This invention relates to ice skates, and in particular to an improved skate blade and skate blade support.
  • Reinforcement would also provide better force transfer between the ice and the skate boot, via the attachments between the boot and the front and rear portions of the blade holder. Reduced weight in skates, without sacrificing performance, is an ongoing goal in the industry. Generally, reducing the weight of the skate blade itself has not been considered to be a viable option, since it was assumed that this would reduce the required stiffness to an undesirable degree.
  • one aspect of the invention provides a rigid reinforcement member extending longitudinally along the at least the neck portion of the blade holder, to reduce stress and improve force transfer.
  • the skate blade assembly of the first aspect of the invention has an elongated blade holder having a front portion for attachment beneath the toe area of the skate boot, a rear portion for attachment beneath the heel area of the skate boot, and an integral neck portion between the front and rear portions.
  • the blade holder has a longitudinal slot running along the bottom thereof to receive a blade or "runner", which is secured in the slot.
  • At least one rigid reinforcement member runs along at least the neck portion, within the slot and above the runner, the slot being enlarged at the location of the reinforcement member(s) in order to accommodate the member(s).
  • the reinforcement member is in one piece, including an upper web portion and an integral channel with a cross-section in the form of inverted U-shape beneath the upper web portion.
  • the arms of the U-shape run alongside the runner, one on either side of the runner, and the base of the U-shape lies against the top of the runner and follows the shape thereof.
  • the rigid reinforcement member is of a reinforced plastic composite material, although a metal could also be used.
  • a second aspect of the invention relates to a skate and skate blade assembly where the runner has a plurality of cutouts, spaced longitudinally along the runner, thereby reducing the weight of the runner significantly, i.e. typically by about 41 grams. That is a significant weight reduction, representing about a 30 percent reduction in the weight of the runner, and about a 4 percent reduction in the overall weight of the skate.
  • the cutouts preferably are arranged in a central area between a solid upper area of the runner and a solid lower area of the runner, extending a substantial portion of the overall length of the runner, in such a fashion that the remaining metal in the central area leaves a truss-like structure between the upper and lower areas, the truss-like structure serving to retain most of the rigidity of the runner.
  • the runner with the suitably-configured cutouts was not significantly less stiff than a conventional solid runner, so that it could be used without necessarily using the reinforced blade holder aspect of the invention.
  • the reinforced blade holder could be used without necessarily using a runner with cutouts, although the optimum blade assembly has the reinforcement, and uses the runner with cutouts.
  • Fig. 1 is an exploded perspective view of the blade assembly, showing a conventional blade holder and runner, with the reinforcement insert of the first aspect of the invention
  • Fig. 2 is a side view of the assembled blade assembly, with a skate boot shown in phantom lines;
  • Fig. 3 is a side perspective view of the assembled blade assembly;
  • Fig. 4 is a side cross-sectional view of the assembled blade assembly
  • Fig. 5 is a cross-section of the blade assembly at 5-5 in Fig. 4
  • Fig. 6 is a cross-section of the blade assembly at 6-6 in Fig. 4
  • Fig. 7 is a cross-section of the blade assembly at 7-7 in Fig. 4.
  • Fig. 8 is an exploded perspective view of the blade assembly, showing a conventional blade holder and runner, with a blade or runner which is provided with suitably-configured cutout areas;
  • Fig. 9 is a side cross-sectional view of the assembled blade assembly of Fig. 8;
  • Fig. 10 is a cross-section of the blade assembly at 10-10 in Fig. 9;
  • Fig. 1 1 is a cross-section of the blade assembly at 1 1-1 1 in Fig. 9;
  • Fig. 12 is a cross-section of the blade assembly at 12-12 in Fig. 9; and
  • Fig. 13 is a side view of an alternative embodiment of the runner.
  • the skate blade assembly 1 is part of a typical skate 2, which also includes a boot 3.
  • the blade assembly includes an elongated blade holder 4 having a front portion 5 with a front pad 6 for attachment beneath the toe area of the boot, a rear portion 7 with a rear pad 8 for attachment beneath the heel area of the skate boot, and an integral neck portion 9 between the front and rear portions.
  • a blade or "runner” 10 is secured in a longitudinal slot 11 running along the bottom of the blade holder, by pins 12 which are pulled upwardly by nuts 13 which contact collars 14.
  • the pins have rounded, flattened heads 23 which fit into appropriately dimensioned rounded slots 24 in the runner.
  • At least one rigid reinforcement member 15 runs along at least the neck portion, within the slot and above the runner, the slot being enlarged at the location of the reinforcement member(s) in order to accommodate the member(s).
  • the reinforcement member is in one piece, including an upper web portion 16 and an integral channel 17 with a cross-section in the form of inverted U-shape beneath the upper web portion.
  • the arms of the U-shape run alongside the runner, one on either side of the runner, and the base of the U- shape lies against the top of the runner and follows the shape thereof, the runner being accommodated within the slot 18.
  • the reinforced blade holder allows the runner itself to be slightly less rigid.
  • the runner therefore can be reduced in weight, for example by a plurality of cutouts 26. This reduces the overall weight of the blade assembly as well, since more weight is removed from the runner than is added by the reinforcement member.
  • the rigid reinforcement member is of a reinforced plastic composite material, such as an epoxy / graphite fiber mix, although a metal could also be used.
  • the reinforcement member provides the desired greater rigidity along the neck portion of the blade holder, thereby reducing the stress on the blade holder. As mentioned previously, this is desirable because the plastic of the blade holder, typically of Zytel (trademark) nylon, is more brittle when under stress.
  • the reinforcement member reduces the stress, and also provides better force transfer between the ice and the skate boot, via the attachments at the front and rear pads between the boot and the blade holder.
  • the reinforcement insert could extend for the whole length or substantially the whole length of the blade holder, not just along the neck portion.
  • the second aspect of the invention relates to the runner being reduced in weight relative to conventional solid runners, by virtue of the cutouts 26.
  • the cutouts are arranged in a central area between a solid upper area
  • the cutouts are triangular, each successive triangle being inverted relative to its predecessor, so that there are ribs 32 between the cutouts, each successive rib angling in an opposite direction, i.e. one forwardly and the next one rearwardly.
  • An alternative is shown in Fig. 1 1 , in which successive semi-circular cutouts of the same orientation could have curved triangular cutouts between them, in effect leaving curved ribs 32, themselves having a semi-circular look. Other similar shapes are clearly conceivable. It should be clear that although the optimum blade assembly has the reinforcement, and uses the runner with cutouts, the reinforcement in itself is advantageous, and can be used without the cutouts, although the advantages of reduced weight may not be realized.
  • cutouts may be used with the reinforcement, although increased stiffness may then not be realized.
  • the invention has been described with particular reference to preferred and alternative embodiments. Various modifications can be made, of course, without departing from the spirit of the invention, and such modifications are intended to be within the scope of the following claims whether or not expressly described in the above text or illustrated in the accompanying drawings.
  • the invention provides an improved ice skate blade and ice skate blade assembly.

Abstract

Un élément de renfort rigide (15) s'étend dans le sens de la longueur d'une partie de col (9) du support de lame de patin (4), afin de réduire les contraintes et d'améliorer le transfert des forces. Le support de lame comporte une fente longitudinale (11) sur toute sa partie inférieure, dans laquelle est logée une lame (10) fixée dans la fente. Au moins un élément de renfort rigide s'étend sur au moins toute la partie de col, à l'intérieur de la fente et au-dessus de la lame, la fente s'élargissant au niveau de l'élément de renfort afin de le loger. De préférence, l'élément de renfort est constitué d'une seule pièce, comprenant une partie de bande supérieure (16) et un canal intégré (17) présentant une section transversale en forme de U inversé au-dessous de la partie de bande supérieure. Les branches du U inversé s'étendent le long de la lame, une de chaque côté de celle-ci, et la base est en appui contre la partie supérieure de la lame et en épouse la forme. De préférence l'élément de renfort se compose d'une matière plastique composite, bien qu'on pourrait également utiliser du métal. La rigidité accrue du support de lame permet d'utiliser une lame plus légère, par exemple une lame ajourée (26). Ces découpes sont situées dans une zone centrale entre une zone supérieure massive et une zone inférieure massive de la lame, de sorte que le métal restant dans la zone centrale forme une structure de ferme à jambes de force entre les zones supérieure et inférieure, cette structure conservant une grande partie de la rigidité de la lame.
