Description
BACKGROUND OF THE INVENTION
This invention relates to a protective shoe adapted to be worn on
the foot in the arts and sports of karate, tae kwon do, kong fu,
kick boxing, etc.
The art of karate, in particular, is a method developed in Japan
for defending oneself without the use of weapons by striking
sensitive areas on an attacker's body with the hands, elbows, knees
or feet. During training in the art and in organized competition,
the use of the feet can become badly bruised from extensive use
thereof. The present invention provides a novel shoe adapted to
prevent injury to the foot and to other persons engaging in the
art.
SUMMARY OF THE INVENTION
It is an object of this invention to provide a novel protective
shoe for use in the above sports, which is designed to protect the
foot of the wearer and which can be easily slipped on or off the
wearer's foot.
Another object of this invention is to provide a novel protective
shoe of simplified construction, relatively inexpensive and which
will obviate injuries to the foot of the wearer and to other
persons while engaging in the various sports mentioned.
Generally, the protective shoe of the invention comprises an open
soled casing of soft resilient material shaped to conform generally
to the foot. Straps are provided for retaining the shoe on the
foot.
Other features and advantages of the invention will become apparent
from the following description of a specific embodiment of the
protective shoe taken in connection with the drawings.
DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of one embodiment of the protective
shoe of the invention;
FIG. 2 is a partial perspective view of the shoe of FIG. 1 showing
permanent-type straps for retaining the shoe on the wearer's
foot;
FIG. 3 is a plan side view of the protective shoe of FIG. 1 being
worn on a wearer's foot;
FIG. 4 is a bottom view of the protective shoe;
FIG. 5 is a perspective view of a second embodiment of the
protective shoe of the invention; and
FIG. 6 is a bottom view of the shoe shown in FIG. 5.
DETAILED DESCRIPTION OF THE INVENTION
The protective shoe embodied in FIGS. 1-4 of the drawings comprises
a device 10 generally conforming in shape to the upper part of a
foot. The device is molded as one piece from a soft resilient
material 10a such as a plastic or rubber foam. During the molding
of the device, surface 10b of the foam material is heated thereby
fusing the surface to produce a tough surface or casing. This
provides a continuous outer tough casing which prevents tearing of
the foam during use. Alternatively, the surface can be toughened by
dipping or applying a coating of a suitable plastic material to
provide the outer casing. The device has an opening 11 into which
the foot of the wearer can be inserted to permit wearing of the
shoe. The bottom 12 of the shoe is open and thereby the sole of the
foot of the wearer of the shoe contacts the floor or ground. This
is in keeping with the various sports mentioned whereby the foot is
used in the contact sports.
The shoe is retained on the foot of the wearer by means of straps
12a and 13. As shown, the straps provided are permanently connected
to the shoe by passing the ends through a strip of material 14
secured to the top of the casing. The strip 14 has slitted holes 15
and 16 which extend through the casing. The ends 17 and 18 of the
straps are passed through the slits and are secured to the
underside of the top of the casing. One purpose of the strip 14 is
to prevent tearing of the casing from tension of the straps.
The straps 12a and 13 are provided with means for detachably
securing the shoe on the foot. As shown, velcro material 19 and 20
can be provided on the free ends of the straps. A felt material 21
and 22 is provided on the straps along the portion which crosses
the top of the casing. When the shoe is put on the foot, the strap
ends 19 and 20 can be brought in contact with surfaces 21 and 22
which retain the strap ends. Adjustment of the straps to the
comfort of the wearer is therefore provided.
Although, straps have been shown using velcro material, it is
understood that other strap arrangements can be used. The straps
can be provided with snaps, laces, and the like for securing the
shoe on the wearer's foot. Thus, as shown in FIG 2, elastic straps
23 and 24 can be provided which are permanently secured to a strip
material 25 secured to the casing.
The casing 10 comprising the soft resilient material can be used as
such. However, as previously stated, to provide a greater
permanence to the casing, the surface thereof can be treated by
various means to toughen it without lessening the resilient
character of the casing. The casing can also be covered with a
fabric material stitched around the surfaces of the casing.
FIGS. 5 and 6 illustrates another embodiment of the protective shoe
of the invention. The shoe indicated generally by the numeral 30
comprises an open bottomed casing 10 similar in construction and
material as the one shown in FIGS. 1-4. The casing is provided with
a plurality of holes 31 for the purpose of providing ventilation.
The casing also is designed to have a portion 32 thereof extend
upwardly for the purpose of covering and protecting the ankle of
the wearer of the shoe.
The shoe is worn on the foot and retained thereon by passing the
big toe through a round strap 33 retained in a hole 34. A second
round strap 33a in hole 34a is provided through which the little
toe can be inserted. A strap 35 is provided which passes through a
series of holes 36, 37, 38 and 39 and is adapted to pass around the
bottom of the foot. When the shoe 30 is on the foot, the ends of
strap 35 can be adjusted and tied together to fit the comfort of
the wearer. Casing 10 is provided with a slitted portion 40 which
permits flexibility of the casing to fit larger or smaller
feet.
Although strap 35 is shown as one that can be tied, it is within
the concept of the invention that elastic straps and straps with
velcro material, as previously described, can be used in place
thereof.
In use, the protective shoe permits the use of the foot as a weapon
in the sports mentioned, without bruising the foot, or causing
serious harm to other persons engaging in the sports.
Although the shoe has been particularly described for use in the
art of karate, it is also contemplated that the shoe can be worn by
contestants in many types of sports such as kick boxing, etc.,
wherein it is not intended to injure the contestants, and wherein
injury to the foot is prevented.
From the foregoing description, one skilled in the art can easily
ascertain the essential characteristics of this invention, and
without departing from the spirit and scope thereof, can make
various changes and modifications of the invention to adapt it to
various usages and conditions.
