Athletic shield
Abstract
A single brace extends upwardly from beneath the shoe to the
thigh where it extends into a pocket in the trousers of the wearer.
The brace has a ball bearing joint in line with the knee joint of
the wearer. The lower member of the brace is made in two parts
which overlap and are rigidly secured together as by screws in
selected matching holes which provide for extension or contraction
of the brace to accommodate different length legs. Protective
padding is provided on the brace at the ankle and thigh.

Claims
I claim:
1. An athletic shield constituting a brace adapted to extend
vertically from the foot to the thigh along the outside of the leg
of an athlete, comprising a lower segment, means to secure said
lower segment rigidly to the shoe of the athlete, a central
segment, means adjustably securing said central segment to said
lower segment to accommodate different length legs of athletes, an
upper segment, a pivotal knee joint between said upper segment and
said central segment adapted to be disposed axially in line with
the knee joint of the athlete, the upper end of said upper section
being free for telescoping confinement in a pocket of the trousers
of the athlete, and said brace being substantially free of leg
constricting attachments which might interfere with the circulation
of blood in the leg of the athlete.
2. The shield of claim 1 in which an arm extends at right angles to
said lower segment for positioning beneath the insole of the shoe
of the athlete, and said first named securing means are adapted to
secure said arm to the insole of the shoe.
3. The shield of claim 1 in which said adjustable securing means
between said lower segment and said central segment of said brace
comprises an overlapping of the ends of said segments with a series
of correspondingly spaced matching holes, and screws disposed
selectively in said holes to provide for adjustment of the heighth
of said pivotal knee joint from the ground to fit the athlete.
4. The shield of claim 1 in which said pivotal knee joint comprises
an overlapping of the adjacent ends of said central segment and
said upper segment, a ball bearing disposed between the overlapping
segments, and means securing said overlapping segments, and means
securing said overlapping segments axially of said ballbearing to
confine the latter therebetween.
5. The shield of claim 1 and thick padding means secured upon the
inside of said lower segment in the region of the shoe and ankle of
the athlete and upon the inside of said upper segment in the region
of the thigh of the athlete to prevent chafing of the leg of the
athlete and retain the central segment spaced laterally from the
knee of the athlete.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an athletic shield for protecting the
ankle and knee of an athlete such as a football or hockey
player.
2. Description of the Prior Art
Heretofore, braces have been provided for the knee, but in every
instance in which applicant is informed the two hinged members are
secured to the leg by a tight band or the like which tends to
interfere with the circulation of blood to and from the lower leg
and foot of the wearer, and used primarily after injury has
occurred.
The same is generally true of ankle braces heretofore employed.
SUMMARY OF THE INVENTION
In carrying out the present invention both the ankle and knee are
protected from lateral and medial bending forces, without
interfering with the normal action of the leg or with the blood
circulation.
For this purpose applicant avoids the use of leg bands in securing
his brace in place.
The brace of the present invention is securely rigidly to the shoe
at its lower end and is telescopingly secured in a pocket in the
trousers above the knee at its upper end.
The brace is constructed of three parts, the lower end part
extending from the sole of the shoe upwardly past the ankle and
along the calf of the lower leg of the wearer, the central part
adjustably overlapping the lower part and rigidly secured thereto
at selected locations to accommodate the length of the lower leg of
the wearer, and the upper part being pivoted at its lower end to
the upper end of the central part as by a ball bearing joint
disposed in axial alignment with the axis of the knee joint of the
wearer, and said upper part extending upwardly to be telescopingly
received in a pocket in the trouser of the wearer at the thigh.
Suitable padding is provided between the brace and the ankle of the
wearer and between the upper part and the thigh of the wearer to
prevent possible abrasion of the leg and to cushion lateral and
medial thrust of the wearer in action.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying drawing illustrates the best mode presently
contemplated for carrying out the invention.
In the drawing:
FIG. 1 is a side elevation of an athlete shown wearing a brace as
provided by the present invention;
FIG. 2 is an enlarged side elevation of the brace and showing in
dark lines several pivotal positions of the upper part;
FIG. 3 is a front elevation of the brace;
FIG. 4 is an enlarged detail of the knee joint and length
adjustment with parts broken away and sectioned;
FIG. 5 is an enlarged detail section showing the pocket of the
wearer's trousers telescoping the upper end of the brace; and
FIG. 6 is an enlarged detail axial section of the knee joint of the
brace.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The athletic shield of the present invention constitutes a brace
comprising in general three members or segments, the lower segment
1, central segment 2 and upper segment 3.
The lower segment 1 is in the form of a rigid strip of suitable
width and thickness adapted to extend from ground level to near the
upper level of the calf of the lower leg of a wearer.
The lower end of segment 1 is formed at right angles to the segment
to provide an arm 4 extending beneath the shoe 5 of the wearer just
in front of the heel 6, as shown in FIGS. 1 and 3. Suitable
fastening means such as screws 7 secure the arm 4 to the sole of
the shoe 5 at the instep.
The upper end of segment 1 has a plurality of vertically spaced
holes 8 therein, preferably threaded to receive screws 9 which
fasten the central segment 2 to segment 1 in selected matching
holes 10 in the central segment to provide for adjustable extension
and contraction of the length of the brace to accommodate wearers
having different leg lengths from the knee to the ground.
For this purpose central segment 2 is constructed as a straight
rigid strip of approximately the same width and thickness as
segment 1 and has a pair of holes 10 spaced vertically along its
lower end to match given holes 8 for adjustment purposes.
The upper end of central segment 2 is connected to the lower end of
upper segment 3 by a suitable pivotal means 11 shown as a ball
bearing pivot in detail in FIG. 6.
The segment 3 is constructed as a rigid strip generally of the same
width and thickness as segments 1 and 2.
The upper end of segment 3 is free to extend through a metal eye 12
into a pocket 13 in the trouser leg 14 of the wearer for suitable
telescoping movement in the pocket.
Chafing of the leg is prevented by thick padding 15 between the
lower segment 1 and the shoe and buckle of the wearer, and thick
padding 16 between the upper segment 3 and the thigh of the
wearer.
The pads 15 and 16 tend to hold the central segment 2 and joint 11
away from the knee of the wearer.
The brace does not interfere with the normal knee action required
of an athlete.
Also, the brace has no bands which restrict circulation of blood in
the leg of the wearer and it protects the ankle against
twisting.
The segments 1, 2 and 3 may be constructed of any suitably stiff
material such as a light weight aluminum alloy or an acrylic
resin.
Various modes of carrying out the invention are contemplated within
the scope of the following claims particularly pointing out and
distinctly claiming the subject matter which is regarded as the
invention.
