LEG PAD FOR A HOCKEY PLAYER
Field of the invention
The present invention relates to a leg pad for a hockey player. The leg pad
provides
adequate protection and flexion in the ankle region of the player.
Background of the invention
In recent years, sporting equipment has been evolving to accommodate the need
for
increased protection. Due to the competitive and aggressive nature of some
sports,
it has been an objective of sports equipment makers to improve protective gear
all
the while permitting flexibility and comfort for the player. However, in many
cases,
an increase in protection can lead to a decrease in maneuverability due to the
rigidity of the protective material.
Conventional hockey leg pads generally comprise two protective portions. One
portion is located in the knee region and the other portion generally protects
the shin
region. However, depending on the length of the shin protecting region, the
ankle
may not be adequately protected. In cases where the shin protecting region
substantially overlaps the ankle, the player may exhibit discomfort while
moving and
skating due to the obstructive nature of the rigid protective material at the
bottom
part of the leg pad. More specifically, the player may experience a limited
range of
motion in occurrences that require flexing the player's ankle. On the other
hand,
should the player need a greater range of motion in the ankle region, the
player may
use a shorter leg pad, but a part of the ankle or forefoot may then be
exposed.
There is therefore a need for a hockey leg pad providing adequate protection
in the
ankle region and having an upper shell and a lower shell is movable relative
to the
upper shell. According to one feature, a band interconnects the lower shell to
the
upper shell such that the lower shell is movable between a first position and
a
1
CA 02931819 2016-05-31
second position in response to flexion of the ankle. The bottom part of the
upper
shell and the top part of the lower shell may overlap when the lower shell is
in the
first position.
Summary of the invention
According to one aspect of the present invention, there is provided a leg pad
for a
hockey player. The leg pad extends along a longitudinal axis and comprises an
upper portion, a bottom portion and a band. The upper portion has a knee cap
for
covering a knee joint of the player. The bottom portion has an upper shell for
covering a substantial part of a shin of the hockey player and a lower shell
for at
least partially covering the shin and ankle of the hockey player. The band
extends
along part of a periphery of the upper shell and part of a periphery of the
lower shell.
The band interconnects the upper shell and the lower shell to one another
wherein
the lower shell is movable relative to the upper shell between a first
position and a
second position in response to flexion of the ankle.
According to another aspect of the present invention, there is provided a leg
pad for
a hockey player. The leg pad extends along a longitudinal axis and comprises
an
upper portion, a bottom portion and a band. The upper portion comprises a knee
cap for covering a knee joint of the player. The bottom portion has an upper
shell for
covering a substantial part of a shin of the hockey player and a lower shell
for at
least partially covering the shin and ankle of the hockey player. The band
extends
along part of a periphery of the upper shell and part of a periphery of the
lower shell.
The band interconnects the lower shell to the upper shell such that the lower
shell is
movable between a first position and a second position in response to flexion
of the
ankle. The upper shell and the lower shell overlap when the lower shell is in
the first
position.

shin of the wearer and a lower protective section for at least partially
covering a
lower part of the shin and an ankle of the wearer. The upper and lower
protective
sections are connected to one another such that the lower protective section
is
movable relative to the upper protective section between an extended position
and a
flexed position in response to flexion of the ankle. When the hockey leg pad
is worn
by the wearer carrying out a skating stride, a bottom edge of the lower
protective
section is configured for at least partially covering the ankle of the wearer
in both the
extended position and the flexed position.

CA 02931819 2016-05-31
With reference to Figures 1 and 2, there is shown a non-limiting example of a
leg
pad 10 in accordance with the invention. The leg pad 10 extends along a
longitudinal
axis A-A and comprises an upper portion 12, a bottom portion 14, a liner 16
and a
band 18. The upper portion 12 comprises a knee cap 20 for protecting the knee
of a
player's leg. The bottom portion 14 comprises an upper shell 22 and a lower
shell
24.
With reference to Figures 3A and 313, the upper shell 22 and the lower shell
24 are
shown in more detail. The upper shell 22 has an outer side 26 and an inner
side 28,
the outer side 26 being opposed to the inner side 28. The lower shell 24 has
an
outer side 30 and an inner side 32, the outer side 30 being opposed to the
inner side
32.
The upper shell 22 also comprises a top edge 38, a bottom edge 40, a left edge
42
and a right edge 44 and the lower shell 24 also comprises a top edge 48, a
bottom
edge 50, a left edge 52 and a right edge 54. The upper shell 22 substantially
protects the shin portion of a player's leg and the lower shell 24
substantially
protects the ankle portion of a player's leg. More specifically, the lower
shell 24
covers the lower front part of the player's ankle and may also cover the
player's
forefoot.
The upper and lower shells 22, 24 may be made of a rigid plastic material for
providing adequate protection in case of impact with a stick, a puck, or
collisions with
another player for example. It is known in the art that hockey leg shells can
be
made of NYLON, polycarbonate materials, thermoplastics, thermosetting resins,
polyethylene, high density polyethylene (HDPE), polypropylene or any other
suitable
material. In one embodiment, the upper shell 22 and the lower shell 24 may be
formed of the same material. In another embodiment, the upper shell 22 and the
lower shell 24 may be formed of different materials. In yet another embodiment
the
upper shell 22 and the lower shell 24 may each comprise a combination of at
least
5
CA 02931819 2016-05-31
two materials. The upper and lower shells 22, 24 may be manufactured or shaped
via any method that is known in the art. For example, the upper and lower
shells 22,
24 may be molded or thermoformed.
The liner 16 is mounted under the upper and lower shells 22, 24 and is adapted
to
be disposed between the upper and lower shells 22, 24 and the player's shin
and
ankle. The liner 16 may be made of any suitable material or composition or
materials
that provide the degree of cushioning and protection that is desired. The
liner 16
may be made of a soft material such as foam, polyethylene, low density
polyethylene (LDPE) or any other suitable material. The liner 16 may also be
made
of foam material covered by layers of woven synthetic yarn, such as closed
cell foam
of ethylene vinyl acetate covered by a mesh outer layer of a woven synthetic
material such as polyester. Such materials would conform itself to the anatomy
of
the player and may dampen any blows that might occur on the upper shell 22 or
lower shell 24. The liner 16 may also be slightly oversized with respect to
the upper
and lower shells 22, 24 such that the liner 16 may further envelop and protect
areas
of the player that are not substantially covered by the upper and lower shells
22, 24.
It is understood that the liner 16 may be omitted if the upper and lower
shells 22, 24
are made, for example, of a rigid outer layer and a soft inner layer affixed
to the rigid
outer layer.
The band 18 extends along part of a periphery of the upper shell 22 and part
of a
periphery of the lower shell 24, the band 18 interconnecting the upper shell
22 and
the lower shell 24 to one another. In one embodiment, the band 18 extends
along
the entire periphery of the assembled upper shell 22 and lower shell 24. In
another
embodiment, the band 18 may extend along a portion of the peripheries of the
upper
shell 22 and lower shell 24.
The band 18 may be a strip of fabric such as a woven stretchable fabric. The
band
18 may also be a braiding.
6
CA 02931819 2016-05-31
The band 18 may have a width large enough to cover at least partially the
outer and
inner sides and edges of the upper and lower shells 22, 24. As shown in
Figures 4A
and 4B, the band 18 is wide enough to cover a portion of the outer and inner
sides
26, 28 and the left and right edges 42, 44 of the upper shell 22 and a portion
of the
outer and inner sides 30, 32 and the left, right and bottom edges 52, 54, 50
of the
lower shell 24. Moreover, as best shown in Figures 4A, 5A and 5B, the bottom
edge
40 of the upper shell 22 and the top edge 48 of the lower shell 24 are free of
the
band 18 such that these edges may move relative to one another.
The leg pad 10 may comprise a stitching line 56 passing through the band 18
and
the upper shell 22 and passing through the band 18 and the lower shell 24 in
order
to affix the band 18 to the upper and lower shells 22, 24 such that the band
18
interconnects the upper shell 22 and the lower shell 24 to one another.
It is however understood that the affixation of the band 18 to the upper shell
22 and
the lower shell 24 is not limited to such stitching. For example, in another
embodiment, the band 18 may be affixed to the upper shell 22 and the lower
shell 24
via an adhesive or any other affixing means known in the art.
Furthermore, the band 18 may be attached to the peripheries of the upper shell
22
and the lower shell 24 such that the band 18 biases the lower shell 24 towards
the
first position. Such a bias would avoid that the lower shell 24 undesirably
remain in
the second position even after the player has extended his/her foot.
The leg pad 10 may also comprise a stitching line 58 passing through the band
18
and the upper shell 22 and liner 16 and passing through the band 18 and the
lower
shell 24 and liner 16 in order to affix the assembled upper shell 22 and lower
shell
24 to the liner 16 such that the band 18 also interconnects the upper and
lower
shells 22, 24 to the liner 16.

CA 02931819 2016-05-31
In either case, the lower shell 24 is movable relative to the upper shell 22
in
response to a flexion motion of the player's ankle. As best shown in Figures
5A, 5B,
6A and 6B, the movement induced by the flexion movement of the player's ankle
will
cause the lower shell 24 to move from a first position to a second position.
As best
shown in Figures 5A and 6A, when the lower shell 24 is in the first position,
the lower
shell 24 may be in an extended position where it extends generally parallel to
the
longitudinal axis A-A of the leg pad such that the upper and lower shells 22,
24 are
generally straight or rectilinear. As best shown in Figures 5B and 6B, when
the lower
shell 24 moves from the first position to the second position in response to
the
flexion motion of the player's angle, the lower shell 24 then pivots about a
pivot
region P and defines an angle 0 relative to the longitudinal axis A-A of the
leg pad.
Hence, in the second position, the lower shell 24 may be in a retracted or
angled
position where it extends along an axis that defines an angle B relative to
the
longitudinal axis A-A. In one embodiment, the angle 0 relative to the
longitudinal
axis may be up to 10 . In another embodiment, the angle 0 relative to the
longitudinal axis may be up to 15 . It is understood that the movement of the
lower
shell 24 relative to the upper shell 22 may be a combination of a pivotable
movement and a slight translation movement that is allowed, for example, by
the
stretchability of the band 18 (see the band 18 in the pivot region P).
As shown in Figure 6A, when the lower shell 24 is in the first position, the
upper and
lower shells 22, 24 are positioned relative to one another to avoid a gap
therebetween. More particularly, in the first position, there is a first
overlap between
the bottom edge 40 of the upper shell 22 and the top edge 48 of the lower
shell 24.
In the first position, the first overlap, when measured along the longitudinal
axis A-A,
may be between 2mm and 12mm. In another embodiment, this first overlap may be
between 5mm and 1 Onnm. When the lower shell 24 is in the second position, as
shown in Figure 6B, there is a second overlap between the bottom edge 40 of
the
upper shell 22 and the top edge 48 of the lower shell 24, the second overlap
being
greater than the first overlap. In the second position, the second overlap,
when
measured along the longitudinal axis A-A, may be between 5mm and 20nnm. In
8
CA 02931819 2016-05-31
another embodiment, this second overlap may be between 15mm and 20mm. As
best shown in Figures 5A, 5B, 6A and 6B, the bottom edge 40 of the upper shell
22
overlaps the top edge 48 of the lower shell 24 in order to avoid a gap when
the lower
shell 24 moves from the second position to the first position.
As best shown in Figures 4B and 7, the leg pad 10 may comprise a strap 60
which
connects the upper shell 22 and the lower shell 24. The strap 60 may be
connected
to the inner sides 28, 32 of the upper and lower shells 22, 24. The strap 60
may
restrict the top edge 48 of the lower shell 24 from moving over the bottom
edge 40 of
the upper shell 22. The strap 60 may also ensure that the lower shell 24
remains
generally parallel to the longitudinal axis A-A of the leg pad 10 when
pressure is
applied on the lower shell for moving/pivoting the lower shell 24 inwardly
(for
example, in a direction towards a player's ankle).
Although various embodiments have been illustrated, this was for the purpose
of
describing, but not limiting, the invention. Various changes, modifications
