Description
BACKGROUND OF THE INVENTION
The game of street hockey has become extremely popular in recent
months due to its demand by athletes who enjoy the sport and the
advancement in design of the street hockey sticks, balls, nets,
etc., used by the players. The ability of this equipment to
withstand the wear encountered on hard-rough surfaces, has been a
major contributing factor in the widespread appeal for the
sport.
It is therefore the purpose of the present invention to provide
very efficient and effective protective padding, designed to
protect the leg in areas including the knee, shin, and ankle. The
ankle being of noticeable interest, whereas protective pads
available on the market today are not designed with this protection
feature, the reason being the design for their use in ice hockey
where ankle protection is provided by the skates worn by the
player. It should also be noted that the present invention will
provide a material capable of resisting abrasive wear encountered
on hard-rough surfaces, while at the same time protecting the
physical parts of the body in the area in which it is worn as well
as the clothing worn in that area.
It is therefore the purpose of the present invention to provide a
protective padding designed for a specific use; to receive and
minimize the blows encountered in street hockey, blows which occur
in areas not governed by protective equipment available on the
market today.
SUMMARY OF THE INVENTION
Two layers of plastic material are prepared and mechanically
secured together. There is an outer layer and an inner layer. The
outer layer is of a harder, flexible, but self sustaining plastic
shaped to adjust to the leg and having means for securing it about
the ankle, leg, and knee. The outer (forward) sheet of plastic is
provided with outstanding protuberances which are hollow and which
absorb blows without injury to the wearer.
A soft foam layer of plastic of the same shape is secured to the
outer layer, the foam layer being the inner sheet of two sheets or
layers, and is applied directly to the body of the wearer providing
for complete comfort and protection for the knee, leg, and
ankle.
The means for connecting the two layers of material together are
inexpensive molded plastic devices which snap into position quickly
and easily securing the layers together and also acting as
anchoring means for snapping on new and improved plastic buckles to
which tapes are adjustably attached for securing the pad to the
leg.

PREFERRED EMBODIMENT OF THE INVENTION
FIG. 1 illustrates the outer of the two layers or sheets that
comprise the padding, and this is generally indicated by the
reference numeral 8. This layer is of molded plastic and comprises
a rounded or bulged out knee portion at 10 to which are integrally
attached lateral wings 12 and a leg or shin portion which is of
semi-cylindrical nature at 14. The portion 14 has lateral wings 16,
16 at the sides thereof and extends into the ankle portion 18 which
is in extension thereof. The wings 20, 20 are not attached to the
ankle portion 18 which must bend forwardly over the ankle and part
of the foot when the device is applied to the leg but nevertheless
it is provided with wings 20, 20 which are however integrally
attached to wings 16, 16 and extend therefrom in a dependant
relation.
The inner foamed layer of material is flat and generally indicated
at 22 and it will be seen that the edges of the outer layer 8 are
bent up to form a rim as at 24 in FIG. 6 to protect the edge 26 of
the foamed rubber layer, preventing the latter from tearing, when
taken into consideration with respect to the mechanical fasteners
30 to be described.
These mechanical snap fasteners each comprise a flat head 32
pressed into the foam material 22 and a shank 34 which extends
through both layers 22 and 8. The shank 34 terminates in a
frusto-conical head 36 and is longer than the combined thicknesses
of the two layers 8 and 22, see FIGS. 5 and 7.
A plastic ring 38 which has a through opening 40 and an interior
inwardly extending shoulder 42 therein snaps behind the
frusto-conical head 36 as shown in FIG. 5 to secure the two layers
quickly and easily together. Ring 38 also has an outstanding rim or
bead 44 at its opposite end and this is used to snap the buckles 46
to the padding.
Each buckle 46 is provided with a central opening having relatively
inwardly enlarged or tapered interior 48 which snaps under the rims
44 of the rings 38 as shown in FIG. 7 thus securing the buckle
thereto. Four buckles are arranged on the pad in the positions
indicated in FIGS. 1 and 2 so that the knee portion 10 is securely
fastened about the knee projecting outwardly to protect the same
and the patella, the wings 16, 16 protecting the leg and the wings
at 20, 20 protecting the ankle.
Each buckle 46 also has openings 50 for the tapes 52 and teeth 54
to adjustably hold the tapes as desired. There are two buckles on
each tape for attachment of the pad to the leg by bending the wings
about the leg and passing the straps behind the leg, then snapping
the tapes on at the desired adjustment.
The front sheet of plastic 8 is provided with outstanding
protuberances as shown at 56 and 58, see particularly FIG. 3. These
protuberances 56 are relatively large and will protect the ankle
bones and the protuberances 58 which extend throughout the entire
sheet 8 form resilient protective hollow portions increasing
greatly the protective qualities of the padding as also do the
transverse protuberances 60 which are on cylindrical surfaces. The
knee area has protective formations also, the foam layer 22 in the
area of the patella has a cross-cut to allow the patella to project
in the protuberance at 10. These protuberances form impact reducing
means as they give under blows but spring back to original
shape.
This padding is strapped about the leg, the wings 12 covering the
sides of the knees, wings 16 protecting the sides and at least
partly the rear of the legs as well as the shins, and the wings 20
covering the ankle bones which project into the molded plastic
protuberances 56. With one buckle 46 of each of the four straps 52
snapped onto a ring 38 at either edge of plastic sheet 8 (right
side thereof as shown in FIG. 1) the other, loose buckle, is passed
behind the leg pulling the wings 12, 16, and 20 into place by
bending them adjacent the edges of the central portions 10 and 14.
The loose buckles are then snapped onto the rings 38 at the
opposite edge of plastic sheet 8, and the entire device is securely
in its protective position with central portion 18 bending out
somewhat over the front portion of the ankle and top of the
foot.
