A protective leg guard having a removable insert for orienting the leg guard on a leg. The protective leg guard includes a protective knee portion having an inner surface generally contoured to substantially overlay the knee. A removable insert is adapted to fit between the knee portion of the leg guard and the knee when the leg guard is worn. The removable insert may be placed in a plurality positions on the inner surface of the knee portion and cooperates with the knee to maintain the leg guard in alignment on the front of the leg.
Description
TECHNICAL FIELD
This invention relates in general to protective leg guards for athletes and more particularly to a removable insert adapted to be fitted between the knee and the inside of the leg guard for providing mounting stability at the leg guard to the athlete and for cushioning the knee.
BACKGROUND OF THE INVENTION
Padded leg guards such, as those utilized by baseball catchers are known in the athletic equipment industry. Typically, these known leg guards include multiple rigid portions of a hardened material configured to conform to the shape of an athlete's leg. The rigid portions are secured together in a manner to permit movement of the leg without obstructing the leg's range of motion.
The inside surface of these known leg guards are typically concave-shaped to conform to the anterior surface of the leg. The inside surface is also typically lined with a padding material for the comfort of the athlete as well as for extra protection. The padding material extends over the inner surface of each rigid portion in substantially a uniform manner. These known leg guards also include a plurality of straps for securing the leg guard to the athlete's leg. The straps extend from one side of the leg guard, extend around the back of the athlete's leg, and then are secured to the opposite side of the leg guard.
However, these known leg guards often become misaligned on the front of the athlete's leg, thereby leaving a portion of the front of the athlete's leg exposed. These known leg guards easily become misaligned during the constant movement of the catcher because the athlete's leg and the inner surface of the leg guard are rounded. This allows the leg guard to rotate to one side of the leg while wearing the leg guard. Also, the leg guard is allowed to rotate when the portion of the leg guard over the athlete's knee is not held closely against the knee. In such case, the gap between the knee and the leg guard is often created by the athlete's bending at the knees.
Some known knee braces have been adapted to include padding. For example, in U.S. Pat. No. 4,116, 236 to Albert, an elastic knee brace which includes a resilient pad disposed between the knee brace and the kneecap is disclosed. The resilient pad overlays the kneecap and variably positions itself with the kneecap when the opening in the knee brace is misaligned with the kneecap. Albert concentrates on maintaining padding around the knee to maintain the localization of pressure and protection of the injured knee even when the brace is misaligned. The resilient pad is mounted within a pocket of the sleeve and permitted to float and align itself with the knee when the knee brace is not properly aligned with the kneecap. Consequently, Albert's pad does not facilitate the proper alignment of the knee brace with the kneecap while the knee brace is being worn.
Accordingly, there is a need for a leg guard capable of continuously protecting the athlete's leg by maintaining the leg guard in proper alignment against the anterior portion of the athlete's leg without compromising the athlete's mobility and flexibility.
SUMMARY OF THE INVENTION
The present invention solves the above-identified problems by providing a removable insert adapted to overlay the athlete's knee. The removable insert cooperates with the knee to continuously orient the leg guard in the proper position on the front of the athlete's leg.
Generally described, the protective leg guard of the present invention includes a rigid knee portion having an inner surface generally contoured to substantially overlay the knee. A removable insert is adapted to fit between the knee portion and the knee when the leg guard is worn. The removable insert is further adapted to be placed in a multitude of positions on the inner surface of the knee portion to substantially overlay the knee. The removable insert cooperates with the knee to maintain the leg guard in alignment on the leg.
The foregoing has broadly outlined some of the more pertinent aspects and features of the present invention. These should be construed to be merely illustrative of some of the more prominent features and applications of the invention. Other beneficial results can be obtained by applying the disclosed information in a different manner or by modifying the disclosed embodiments. Accordingly, other aspects and a more comprehensive understanding of the invention may be obtained by referring to the detailed description of the exemplary embodiments taken in conjunction with the accompanying drawings, in addition to the scope of the invention defined by the claims.

DESCRIPTION OF A PREFERRED EMBODIMENT
Referring now to the drawings in which like numerals indicate like elements throughout the several views,
FIG. 1
illustrates an exemplary embodiment of a leg guard
10
of the present invention. The leg guard
10
may be a baseball catcher's leg guard, a goalie's leg guard, a leg guard for some other type of athletic event, or for other activities requiring protection of the leg including the thigh, knee, shin, ankle and/or foot. However, the leg guard
10
shown in
FIGS. 1-3
illustrates the present invention in the form of a baseball catcher's leg guard.
As best shown in
FIGS. 1-3
, the leg guard
10
includes a rigid outer knee portion
12
, a rigid and elongated outer shin portion
14
, a rigid outer ankle and foot portion
16
, a first rigid outer thigh portion
18
and a second rigid outer thigh portion
20
for overlying the leg. Other embodiments of the leg guard
10
of the present invention may include only the knee and shin portions
12
and
14
of the leg guard
10
. The knee portion
12
, shin portion
14
, ankle and foot portion
16
, and thigh portions
18
and
20
are molded from polyethylene or any other hard material suitable for providing protection from impacts to the leg.
The knee portion
12
, shin portion
14
, ankle portion
16
, and thigh portions
18
and
20
each have a padded backing
24
extending substantially over the entire back surface of each of the rigid portions
12
,
14
,
16
,
18
, and
20
. The rigid portions are attached to one another with fasteners, straps or by any other means suitable for attaching the portions together without compromising the user's flexibility or mobility. The rigid portions
12
,
14
,
16
,
18
,
20
and padded backing
24
cooperate together to conform the leg guard
10
to the athlete's leg. The padded backing
24
may be a soft dense foam known in the industry or any other material suitable for providing additional protection between each of the rigid portions
12
,
14
,
16
,.
18
and
20
of the leg guard
10
and the leg while also allowing some degree of comfort for the athlete while wearing the leg guard
10
.
The leg guard
10
may include a plurality of elongated flexible members such as straps
30
with hook fasteners
32
for fastening the leg guard
10
to the leg by extending from rivets
34
on one side of the leg guard
10
, around the back of the leg, and hooking with the hook fasteners
32
to D-rings
36
or other suitable loop fasteners. Preferably, the straps
30
are adjustable to accommodate different sizes of legs.
Still referring to
FIGS. 1-3
, the present invention includes a knee receptacle
40
sized to fit between the knee portion
12
of the leg guard
10
and the knee while the leg guard
10
is worn. Knee receptacle may be an integral component of leg guard
10
, or it may be an independent insert. The knee receptacle is preferably made of the same material as the padded backing
24
described above. However, other cushioning materials may be substituted which are capable of filling a space, giving shape, and to protect against injury. The knee receptacle
40
is preferably annular or unshaped, but may be shaped in an alternative manner suitable for overlaying the knee.
FIG. 4
illustrates one embodiment of the insert
40
of the present invention. The insert
40
is annular having side walls
41
of a predetermined height defining a central cavity
44
for receiving the knee. A pair of opposing cut-out portions
50
extends through the outer edge portion
48
of the insert
40
and into the central cavity
44
. The cut-out portions
50
preferably having a length greater than a width and are aligned lengthwise with one another to partially define fold line
52
extending the full height of the insert
40
. When the insert
40
is placed over the knee, the fold line
52
allows the insert
40
to fold somewhat to allow the insert
40
to more completely overlay and conform to the knee.
As best shown in
FIG. 5
, the insert
40
may also include a second central cavity
54
disposed on the back side opposite the first central cavity. A second pair of cut-out portions
56
may also be included to oppose cut-out portions
50
so that the front and back of the insert are mirror images enabling a catcher to quickly place the insert in position. Preferably, the insert
40
is made up of multiple layers of padding. For example, the cavity
44
may be one layer of padding and the outer edge portion
48
may be made up of at least two portions of padding over the top of each other to provide the greater thickness when compared to the padding of cavity
44
. In this case, the insert
40
is three layers of padding. The padding of the cavity
44
is preferably thinner than any single layer of the outer edge portion
48
.
Referring back to
FIGS. 1-3
, the insert
40
is sized to remain on an inner surface
60
within the confines of the knee portion
12
. When the leg guard
10
is worn, a gap or void may form between the knee portion
12
and the knee. The insert
40
may assume any number of positions within the knee portion
12
to fill this gap. Because the insert
40
overlays the knee and fills any void created between the knee and the knee portion
12
of the leg guard, the insert
40
is continuously urged by the knee against the inner surface
60
of the knee portion
12
which results in the leg guard
10
maintaining the proper alignment on the front anterior portion of the leg while the leg guard is worn.
The removable inserts
40
,
70
are preferably detachably secured to the inner surface
60
of the knee portion
12
of the leg guard
10
. When the removable inserts are secured to the leg guard, they function as an extension of the leg guard which receives the catcher's knee. When the knee is received within the central cavity of the insert, preferably no clearance exists between the knee and the side walls. Thus with the insert fixed in position with the leg guard, the leg guard is anchored with respect to the catcher's knee preventing the leg guard from twisting out of position to allow variable positioning in the knee portion
12
by removing the insert from one position and then reattaching the insert in another position on the inner surface
60
. To detachably secure either of the inserts
40
,
70
to the inner surface
60
, hook and loop fasteners
74
may be utilized as shown in FIG.
5
. The hook and loop fasteners
74
may be attached along the outer edge portion
48
on one side of the insert
70
. Alternatively, the second central cavity
54
on the back of insert
40
may be shallower than the first central cavity
44
on the front of the insert so that hook and loop fasteners
74
may be attached to the back of the insert
40
to engage the inner surface
60
. Preferably, the padding
24
on the inner surface
60
is suitable for securing the inserts
40
,
70
with the hook and loop fasteners
74
.
Alternatively, each one of the inserts
40
,
70
may be positioned between the knee and the knee portion
12
while the leg guard
10
is worn such that the combination of the catcher's knee and the elastic urging of the leg straps maintain the inserts in place through compressive forces. Consequently, the inserts
40
,
70
are free of any means for fixed attachment to the inner surface
60
of the knee portion
12
, but the leg guard
10
is maintained in the desired position on the front anterior portion of the leg because the inserts are immobile and anchored with respect to the catcher's knees.
To allow the inserts
40
,
70
to free-float, an elongated flexible member such as a strap
78
secures the inserts
40
,
70
to the leg guard
10
. In
FIG. 6
, the insert
70
includes a strap
78
looped back over itself to form a loop for receiving one of the straps
30
used for securing the leg guard
10
to the leg. The looped strap
78
allows the insert
70
to move up and down along the length of one of the straps
30
when the insert
70
is not between the knee and the knee portion
12
of the leg guard
10
. The length of the strap
78
is preferably long enough to define a loop sufficient to extend out from between the leg guard
10
and the leg.
Although the use of the inserts
40
,
70
described above constitute an inventive leg guard
10
as described above, the combination of inserts
40
,
70
as described above also constitute an inventive kit of inserts for use with leg guards. In one embodiment, the kit of inserts includes the insert
40
together with the insert
70
as described above. Either of the inserts
40
,
70
may optionally include hook and loop fasteners
74
for detachably securing the inserts
40
,
70
to the inner surface
60
of the knee portion
12
of the leg guard
10
or the strap
78
for allowing the inserts
40
,
70
to free-float as described above.
FIG. 6
illustrates an alternative embodiment of a removable insert
70
for overlaying the knee. The insert
70
also includes the outer edge portion
48
. However, the outer edge portion
48
of the insert
70
defines an opening
72
through the insert
70
for receiving the knee. The insert
70
is also foldable at fold line
52
.
FIG. 7
best illustrates cut-out portions
50
and
56
in the insert
70
which partially define fold line
52
.
