LEG GUARD
Abstract
A leg guard for use by hockey players includes a relatively
rigid shin piece and a knee cap, both of which are connected
together and backed by a padding material. A flap connects with the
lower end of the shin piece, and that flap may either be folded
backwardly across the lower end of the shin piece and into the
interior of the leg guard, or else it may be extended and caught
under the tongue of the skate shoe to provide additional protection
for the player's instep. The padding behind the knee cap retains an
auxiliary pad which wraps around the player's leg at the knee, and
that auxiliary pad affords added protection for the fibro cartilage
and helps protect the medial collateral ligaments by stabilizing
the medial and lateral condyles when impacts are received at the
knee.

Description
BACKGROUND OF THE INVENTION
This invention relates in general to athletic protective equipment
and more particularly to leg guards for athletic contests.
It is common practice to protect the legs, and particularly the
shins of the athletes such as ice hockey players with leg guards
which extend from the vicinity of the knees to the ankles. These
leg guards are normally held in place merely by the heavy knit
stockings worn over them, and since ice hockey is a rigorous sport
involving considerable body contact, the leg guards tend to shift
out of place. Consequently, hockey players are constantly adjusting
their leg guards. Moreover, leg guards of current design do not
provide protection for the player's insteps, which in ice hockey
are often struck by opposing player sticks. Also, leg guards of
current design do not provide any additional protection for the
vulnerable fibro cartilage and anterior ligament of the knee. If
these are injured the hockey player may be disabled for weeks.
SUMMARY OF THE INVENTION
One of the principal objects of the present invention is to provide
a leg guard which is comfortable and allows the wearer sufficient
freedom of movement to participate in rigorous athletic contests
such as ice hockey. Another object is to provide a leg guard which
remains in place, even during rigorous athletic contests involving
considerable body contact. A further object is to provide a leg
guard which is light in weight, simple in construction, and easy to
manufacture. An additional object is to provide a leg guard which
provides protection for the player's instep. Still another object
is to provide a leg guard which affords adequate protection for the
vulnerable fibro cartilage of the knee. These and other objects and
advantages will become apparent hereinafter.
The present invention is embodied in a leg guard having a
relatively rigid shin piece and a flexible end flap at the lower
end of the shin piece. The flap is connected with the shin piece in
such a manner that it may either be folded into the interior of the
leg guard or else extended as a continuation of the shin piece. The
invention also resides in a leg guard having auxiliary padding
along the front and sides of the knee to provide additional padding
for the fibro cartilage and anterior ligament of the knee. The
invention also consists in the parts and in the arrangements and
combinations of parts hereinafter described and claimed.

DETAILED DESCRIPTION
Referring now to the drawings, 2 designates a leg guard including
(FIG. 1) a curved thin piece 4 and a cup-shaped knee cap 6, both of
which are molded or otherwise formed from a relatively rigid
plastic material such as polyethelene. Preferably the polyethelene
has multitudes of minute air cells blown into it to improve its
flexibility and its shock absorbing characteristics. Such a
polyethelene material is available from the Rawlings Sporting Goods
Company of St. Louis, and is marketed by them under the trademarks
ARMOR-FLEX. The shin piece 4 is shaped to wrap around and generally
conform to the contour of the user's shin. The knee cap 6 is
contoured to form a pocket for the knee, and has a pair of
corrugations a and b at the center thereof. The corrugation a is
actually surrounded by the corrugation b, and the two in
combination impart a stepped configuration to the forward surface
of the knee cap 6. Since the thickness of the knee cap 6 does not
change through the corrugations a and b, the corrugations a and b
create a stepped pocket on the opposite side of the knee cap, that
is the side presented toward the user's knee. The corrugations a
and b protect the patella and the patellor ligaments from impacts
so that they are not so easily injured.
Disposed behind the shin piece 4 is a backing piece 7 (FIG. 4)
which in turn is backed by a padding material 8. The backing piece
7 is for the most part spaced from the shin piece 4, but the two
abut adjacent to the side margins of the shin piece 4 where the
shin piece 4, the backing piece 7, and the padding material 8 are
all secured together by a run of stitching 10 which follows but is
set slightly inwardly from the peripheral margin of the shin piece
4. The padding material 8 and backing piece 7 are further connected
by an adhesive. The padding material 8 continues beyond the side
margins of the shin piece 4 in the formation of side flaps 12, but
the lower margin of the padding material 8 terminates prior to the
curved lower margin of the shin piece 4 and the run of stitching 10
does not extend along that margin.
The knee cap 6 is likewise attached to the padding material 8,
being secured thereto by a run of stitching 16 which extends
completely around the knee cap adjacent to its peripheral margin.
The padding material 8 furthermore extends entirely across the
inner face of the knee cap 6 and continues outwardly beyond its
upper and side edges in the provision of an upper flap 18 and side
flaps 20. At its center the knee cap 4 is embossed outwardly
slightly due to the presence of the corrugations a and b therein
and contained within the pocket formed on the opposite side of this
embossment is an additional pad 21 (FIG. 7) which is held in place
by an adhesive.
The portion of the padding material 8 which extends between the
shin piece 4 and the knee cap 6 constitutes a connecting segment
22, and the connecting segment 22 has side flaps 23 extending from
it, those side flaps being interposed between the side flaps 12
extending from the shin piece 4 and the side flaps 20 which project
beyond the knee cap 6.
The padding material 8 is quite flexible and is preferably formed
from a foamed plastic composition such as polyvinyl chloride.
The connecting segment 22 is further protected by an additional
layer of armor 24 (FIG. 1) which is disposed between the upper
margin of the shin piece 4 and the lower margin of the knee cap 6,
and that armor includes a plastic strip and padding encased in a
leather covering 26. The covering 26 extends upwardly and
downwardly from the armor 24 and is captured in the runs of
stitching 10 and 16. The side edges of the leather covering 26 are
further attached to the connecting segment 22 of the padding
material 8 along runs of stitching 28.
The lower edge of the shin piece 4 is completely covered by a thin
piece of leather covered padding 30 (FIGS. 2-4) which is folded
over upon itself along a fold line 32 in the formation of front and
rear segments 34 and 36, and those segments are stitched together
along their sides by runs of stitching 38 so as to form a pocket
into which the lower end of the shin piece 4 is fitted. The leather
cover on the folded padding 30 is presented away from the
underlying shin piece 4, and the padding 30 is secured to the shin
piece 4 by a center rivet 39 which passes through only the front
segment 34 and the lower end of the shin piece 4 and by a pair of
end rivets 39 which pass through both the segments 34 and 36 and
are set slightly inwardly from the side margins of the shin piece
4. The lower margin of the padding 30 is of course the fold line 32
and it is located below the lower margin of the shin piece 4.
The padding 30 has a lower end flap 40 connected to it such that
the flap 40 may either be extended beyond the padding 30 without
doubling back upon itself (FIGS. 2-4) or else folded backwardly
across the fold line 32 into the interior or the leg guard 2 (FIGS.
5 and 6). In particular, the flap 40, like the padding 30, is
formed from leather covered padding material with the leather
covering presented forwardly. It includes an attaching portion 42
(FIGS. 2 and 4) having an arcuate upper edge and that portion is
secured to the outer segment 34 of the folded padding 30 along an
arcuate run of stitching 44 which is located slightly inwardly from
that arcuate upper margin. At the end of the run of stitching 44
the side margin of the lower flap 40 flares outwardly and
thereafter turns back inwardly so as to form a tongue 46. The flap
40 at the juncture of its attaching portion and tongue 46 is also
connected to the folded padding 30 along another run of stitching
48 which passes through the padding 30 at the fold line 32 therein.
The run of stitching 48 is substantially straight and is located
slightly to the forward side of the fold line 32.
Finally, the portion of the padding material 8 which is located
behind the knee cap 6 is provided with a pair of parallel slits 50
(FIGS. 5 and 7) which extend vertically and are disposed closer to
the lower portion of the run of stitching 16 than to the upper
portion of that run. The slits 50 retain an auxiliary pad 52 which
consists of generally circular end portions 54 which are connected
by a narrow connecting portion 56. The connecting portion 56 is
extended through the slits 50 with most of it presented between the
padding and the knee cap 6, while the generally circular end
portions 54 are presented along the inside or rear faces of the
side flaps 20. In this connection, it should be noted that the end
portions 54 are located generally at the bottom of the knee cap 6
so that when the leg guard 2 is fitted to the user's leg the end
portions 54 will be disposed generally to the side of the knee
joint. The auxiliary pad 52 is formed from the same type of padding
material as the padding 8, but it is slightly thicker. Preferably,
the auxiliary pad 52 is inserted through the slits 50 before the
padding material 8 is stitched to the knee cap 6 along the run of
stitching 16.
In use the leg guard 2 is placed against the player's leg with the
knee cap 6 in front of his knee and the shin piece 4 in front of
his shin. The side flaps 12, 20 and 23 will accordingly extend
along the sides of the player's leg, while the generally circular
end portions 54 of the auxiliary pad 52 will be located to the
sides of the knee joint in the leg. After the leg guard is so
emplaced, the player pulls a heavy knit stocking over the entire
leg guard 2 to hold it in the previously described position.
The player has an option as to the dispostion of the lower flap 40
in use. First he may fold it into the interior of the leg guard 2
and tuck its free end between the backing piece 7 and the shin
piece 4 (FIGS. 5 and 6), in which case it will fold across the fold
line 32 and overlie the rear segment 36 of the padding 30 as well
as the lower end of the padding material 8. In that position the
flap 40 affords extra protection for the lower portion of the
player's shin. In the alternative, the player may allow the flap 40
to extend beyond the fold line 32 as a flexible continuation of the
shin piece 4 (FIGS. 2-4). In that case, the flap 40 can and should
be tucked into the upper portion of the player's skate. When fitted
into the player's skate, the flap 40 secures the entire lower end
of the leg guard 2 and prevents it from shifting out of position,
even during vigorous skating or checking as is often encountered in
ice hockey matches. The flap 40 also provides additional protection
for the player's instep when tucked into the skate.
Since the flap 40 is stitched to only the front segment 34 and fold
line 32 of the folded padding 30, and not to the rear segment 36,
the flap 40 may be extended without doubling back upon itself and
thereby creating an uncomfortable ridge or protrusion behind the
rear segment 36 as is true in leg guards of current manufacture.
Nevertheless, the flap 40 may still be folded inwardly to provide
additional padding at the lower interior end of the shin piece
4.
Inasmuch as the generally circular end portions 54 of the auxiliary
pad 52 are positioned at the side of the knee joint in the leg,
they provide additional padding for the fibro cartilage and they
help protect the medial collateral ligaments of the knee, both of
which are quite vulnerable from the sides of the knee joint. This
is a very important area for protection, since an injury to the
fibro cartilage or medial collateral ligaments could disable a
hockey player for weeks.
This invention is intended to cover all changes and modifications
of the example of the invention herein chosen for purposes of the
disclosure which do not constitute departures from the spirit and
scope of the invention.
