Ice skate blade and assembly
Abstract
The present invention relates to an ice skate blade holder and
blade assembly which comprises a blade holder and a blade, wherein
said skate blade holder includes two pin holes respectively located
at the bottom of the front and rear aspects of said blade holder.
The blade is secured with the blade holder by pins and nuts
extending through said pin holes. The blade has an upper and a
lower portion which are adhered to each other by glue. The lower
portion of the blade provided with great wear-resistant and rigid
material has an elongated protrusion extending along upside. The
upper portion of the blade provided with lighter aluminum material
includes an accommodated slot extending along the bottom thereof
and two round slots respectively located at the upper edge
thereof.

Description
BACKGROUND OF THE PRESENT INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an ice skate blade
assembly, more particularly to a blade comprising a upper portion
and a lower portion thereof, wherein the lower portion of the blade
includes highly wear-resistant and rigid material, and the upper
portion of the blade composed with lighter aluminum material, so as
to contribute to a blade with lighter material and better
wear-resistance.
[0003] 2. Description of Related Invention
[0004] Referring to FIG. 3 of the drawing, a conventional skate
blade which is initially in the module of one embodiment increases
the weight of the blade and inflexibility for the user. As for FIG.
4 of the drawing, the U.S. Pat. No. 6,761,363 issued on Jul. 13,
2004 to Richard J. Fask et al, an improvement structure of the
blade is described, wherein the structure comprises a blade with
replacing part of the rigid material with lighter plastic material
in order to reduce the weight of the blade and keep the rigidity of
the lower part of the blade. However, the method of material
replacement still suffers from some disadvantages as follows.
[0005] Firstly, the lighter plastic material referring to polymeric
resin with worse wear-resistance contributes to less practicability
of the blade because the surface of the plastic material of the
blade is more brittle when under artificial process of maintenance,
more particularly, under high speed friction against the ground
surface.
[0006] Secondly, with the characteristic of stiffness but brittle,
the polymeric-resin plastic material directly or indirectly effects
the practicability of the blade when under strong impact against
the ground because of the large movement made by the user during
competition or performance.
[0007] Thirdly, the plastic material is easily affected by the
extremely cold or hot weather so as to destroy the particle
structure and shorten the life span of the blade.
[0008] Fourthly, the nature of the plastic material doesn't fit the
eco-awareness issue for its non-recyclable property which is not
composed of natural chemical material.
SUMMARY OF THE PRESENT INVENTION
[0009] In view of the foregoing disadvantages, the present
invention relates to an ice skate and skate blade assembly, wherein
the blade of the preferred embodiment is divided into an upper and
a lower portion. More particularly, the lower portion of the blade
is manufactured with greater wear-resistant and rigid material, and
the upper portion of the blade is composed of lighter aluminum
material. With such improvement, the blade would permit the overall
weight reduction and maintain the highly wear-resistance as well.
Preferably, by providing the upper portion of the blade with
lighter and rigider aluminum material, it contributes to the
advantages as follows.
[0010] Firstly, the upper portion of the blade could be reduced in
weight and probability of damage when under friction stress
accordingly. Secondly, the flexibility and the tractility nature of
the aluminum material protect the blade from being easily damaged
when under powerful impact against the ground surface and extremely
weather change. Thirdly, the recyclable aluminum provided by metal
material is totally in accordance with the eco-awareness concept so
as to reduce the waste of social costs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] Referring to FIGS. 1, 2, 2-1 of the drawings, the present
invention includes a blade holder (10), a blade (20), wherein the
blade holder (10) is secured with the blade (20) by pins (30) and
nuts (31) extending through the holes positioned respectively at
the bottom of the front and rear portion of the blade holder (10).
The blade (20) includes an upper portion of the blade (21) and a
lower portion of the blade (22) adhered to each other by glue which
is tolerant to heat and cold, preferably not easily falling apart.
The lower portion of the blade (22) is able to accommodate to the
friction stress by providing it with the wear-resistant and great
rigid material. An elongated protrusion (221) which is thinner
extends along upside the lower portion of the blade (22). The
purpose of reducing the overall weight is permitted by providing
the upper portion of the blade (21) with lighter aluminum material.
At the bottom of the upper portion of the blade (21) is positioned
with an accommodated slot (211). The head of the pins (30) suitably
fit into round slots (212) which are respectively equipped on two
upsides of the upper portion of the blade (21).
[0017] The accommodated slot (211) positioned along the bottom of
the upper portion of the blade (21) is engaged with the elongated
protrusion (221) extending along upside the lower portion of the
blade (21) so as to provide a lighter and greater wear-resistant
blade (20). The blade holder (10) is secured with the blade (20) by
the head of pins (30) suitably fitting into the round slot (212)
and locked with the nuts (31).
