Definitions
- This invention relates to ice skates, and in particular to an improved skate blade and skate blade support.
- a blade holder which is secured to the skate boot, has a longitudinal slot into which the blade or "runner" is installed.
- US-A-3 212 786 relates to a skate with a reinforcing member, comprising the characteristics of preamble of claim 1.
- the invention provides an ice skate blade assembly according to claim 1.
- 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.
- 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 28 of the runner and a solid lower area 30 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 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.
- 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.
- the cutouts may be used with the reinforcement, although increased stiffness may then not be realized.
- the invention provides an improved ice skate blade and ice skate blade assembly.
