Description
BACKGROUND OF THE INVENTION
This invention relates generally to athletic protective devices,
and more particularly to a device to protect hockey players from
foot injury by a flying puck and the like.
Not too long ago, serious hockey activity was, for the most part,
restricted to cold winter climates, as evidenced by the fact that
almost all National Hockey League and most good other professional,
semi-professional league and college hockey players came from
Canada, only a few coming from northern states like Minnesota. This
was because natural ice is available continuously for several
months of the year. Hard natural ice in areas farther south is
available only a relatively few days during the entire winter.
However, with the advent of artificial ice rinks, hockey ice is
available nearly all year around, in municipal rinks and rinks
operated as businesses for profit, often under the name of a
professional star. As a result, participation in amateur hockey, on
an organized basis, has experienced a tremendous upswing,
particularly in the United States.
In addition to expansion of the National Hockey League and greater
college participation, more and more high schools are adding hockey
to their athletic program. Further, numerous well-organized hockey
leagues are in operation for children of all ages. The fact is that
many artificial rinks are in use all day and on into the late night
and early morning, and there are waiting lists for league use.
Being a game of flying hard pucks, swinging hard sticks and steel
skate blades, the probability of injury is considerable, including
serious injury to the ankle or foot. Even professional hockey
players, using the best lined or padded hockey skates available,
suffer disabling foot and ankle injuries due to blows or
penetration of the skate shoe. It is difficult to estimate how many
such injuries are sustained in amateur hockey, where unlined or
unpadded skates are common, but any such injury, particulary to
children, should be avoided, if possible.
Another problem is that where an amateur goalie is not using
special goalie skates, it is possible, as it sometimes does, for
the puck to pass through the space between the skate shoe and the
blade.
SUMMARY OF THE INVENTION
The invention is directed to the elimination of foot and ankle
injuries of the type referred to above, and, with a simple
modification, converts any hockey skate into the equivalent of a
goalie skate.
Accordingly, an object of the invention is to provide a device for
preventing foot and ankle injuries to hockey players.
Another object of the invention is to provide such a device that
may be purchased in the proper size at the same time that the
skates are purchased or anytime.
Another object of the invention is to provide such a device that is
inexpensive to manufacture, easy to attach or remove and durable in
use.
Still another object of the invention is to provide such a device
that does not detract from the appearance of the hockey or other
skate and that does not limit or in any way interfere with the
necessary freedoms of movement of the hockey player.
A further object of the invention is to provide such a device that
is lightweight, but considerably more resistant to indentation or
penetration than leather or other material from which skate shoes
are made.
These and other objects and advantages of the invention will become
more apparent by reference to the following specification and the
appended drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, wherein like reference numerals are
applied to like elements in the various views, and specifically to
FIGS. 1-4, 10 is a hockey type skate shown in broken lines for
purposes of illustrating application of the invention. The skate
10, which is not a goalie skate, as anyone will recognize, includes
(a) the leather ankle-high shoe portion 12 formed to provide a sole
14, a toe 16, an instep 18 and a heel 20 and (b) the blade portion
22 formed to provide the blade 24 and the blade spacing and
attaching members 24a, 24b and 24c.
The shoe is usually made of leather so as to be relatively soft and
pliable and to substantially conform to the shape of the foot and
ankle when the shoe laces 27 are properly tightened. Being
relatively pliable and tightly fitted on the foot, the leather is
subject to indentation upon receiving a sharp blow, and the force
of the blow is transmitted directly to the foot, causing varying
degrees of injury.
A degree of pliability in a skate shoe is necessary in order to
allow certain freedom of movement in the ankle, but the pliability
that allows the movement also allows the indentation and
injury.
There is available an ankle support insert for hockey skates, but
since it is fitted over the foot before insertion thereof into the
skate, for side-to-side support to prevent weak ankle inward or,
more frequently, outward, as opposed to the desired verticle,
positioning of the blades, it is bulky and, to varying degrees, it
interferes with proper tightening, freedom of movement and blood
circulation in the foot.
As seen in FIGS. 1-4, the invention comprises a guard 26,
preferably made from a tough and relatively hard, indentation and
puncture-proof plastic material, molded to substantially conform to
the shape of the shoe. The device should be moisture non-absorbent,
resistant to cracking at freezing temperatures and thin-walled so
as to be lightweight. Even though the invention can be practiced
employing various materials, various successful embodiments of the
invention have been made by using such materials as an
acrylonitrile-butadiene-styrene copolymer, polypropylene, and
polycarbonate resin. The preferred material is LEXAN-500 which is a
General Electric Corp. trademark for thermoplastic carbonate-linked
polymers produced by reacting bisphenol A and phosgene. The
characteristics of such LEXAN-500 are further described in a
General Electric Corporation publication entitled LEXAN 500 and
bearing a number CDC-532, 11-70 (5M).
As shown, the guard 26 has a toe portion 28 fitting over and
protecting the toe 16 of the shoe, which, incidentally, is the
first portion of a hockey skate to get defaced, often severely, by
skate blades.
Extending rearwardly from the toe portion 28 is an integral side
portion 30 terminating at the other end in a heel portion 32, the
side 30 also having at the bottom thereof an instep portion 34.
Adjacent the toe 28 is an outwardly offset or bulging portion 36 to
accommodate the portion of the shoe fitting the ball of the foot
and the shoe construction at the toe 16.
At the bottom of the guard, all around the toe 28, along the instep
34 and back to the heel 32, is an inwardly extending lip or flange
38 which is of a size and shape so as not to interfere with the
means (usually plates at the top of elements 24a, 24b and 24c
riveted to the shoe sole 14) attaching the blade 22 to the
shoe.
The guard 26 can, of course, be molded in any color, or
combinations of colors, and finish, and in specific sizes and
shapes to fit all makes of skates.
For use, the guard 26 is merely fitted on the skate 10, as shown in
FIG. 1, and secured semi-permanently or permanently, as by
stapling, moisture-proof cementing or otherwise suitably attaching
the flange 38 to the portion of the sole 14 engaged thereby.
Since the shoe toe 16 is completely enclosed by the toe 28 of the
guard 26 so as to anchor the guard in position and since the guard
is attached along the length of the flange 38, no other attaching
means is required. That is, the guard 26 is secured to rigid
portions of the shoe so that freedom of movement is in no way
affected. Also, since the guard 26 is on the outside of the shoe,
it does not in any way adversely affect shoe fit. In fact, as far
as the skater is concerned, he doesn't even know the guard is in
place, except that he will not feel a blow from a flying puck to
the extent he would if the guard were not there.
In FIGS. 5-7, strips 40 or any other desired form of material
similar to pressure-sensative type weather stripping material are
applied to the inner surface of the guard 26. Thus, when the guard
26 is fitted on the shoe, it will be spaced therefrom to provide
additional protection.
In FIG. 8, the flange 38 is formed with an integral tab 42 of
suitable size, shape and location to block the opening between the
blade 22, the sole 14 and the members 24a and 24b, to prevent
passage of the puck therethrough, and thereby converting the usual
hockey skate to the equivalent of a goalie's skate, which is made
to close such openings.
In FIGS. 1-7, the guard 26 covers and protects the toe and only the
instep side of the skate. However, a hockey defenseman, in
particular, would benefit from protection at the outside, rather
than the instep side, of the skate.
FIG. 9 illustrates how the invention is adapted to alternatively
protect either only the outside of the skate, or both sides of the
skate. In FIG. 9, the guard 27 has, in addition to the toe 28 and
the instep side 30, an integral outside portion 44, also having the
flange 38 and terminating in a heel portion 32. Since the heel
portions 32 of the sides 30 and 44 are not joined, the guard 26 is
just as easily assembled on the shoe as the guard 26 having only
the instep side 30. Means 48, may, however, be provided to connect
the heel portions 32 for additional support.
Alternatively, as shown in FIG. 9, the guard may be formed so as to
have only the toe 28 and the outside portion 44, and with a tab 42,
if desired, as would be the case if guard 27 were severed at the
line 46.
It will be noted, in the preferred embodiment of the invention
shown in FIG. 1, that the edge 47 is positioned so that it does not
interfere with manipulation of the shoe laces 27.
A particular hockey player might, for example, desire one outside
guard and one instep guard, or one one-sided guard and one
two-sided guard.
While several preferred embodiments of the invention have been
illustrated and described, in such clear and concise terms as to
enable one skilled in the art to practice the same, it will be
apparent that certain modifications may be made within the scope of
the appended claims.
