Description
BACKGROUND OF INVENTION
Helmets used in wrestling are essentially ear protectors, designed
to cover and protect the ears against injury. These helmets are
generally constructed of a pair of ear guards, one for each ear of
the wearer, with the guards being interconnected by suitable
straps.
Examples of this type of helmet are shown in the prior art U.S.
Pats. to Keen No. 2,898,596 of Aug. 11, 1959 and Roberts No.
2,886,818 of May 19, 1959.
Such prior types of wrestling helmets have been characterized by
being relatively bulky, with a number of straps, particularly
including a forehead strap, wherein the helmet may be grasped
during the wrestling activity and twisted upon the wearer's head.
Forehead straps particularly, tend to apply heavy pressures upon
the sinus area of the head causing headaches and the like after
wrestling activities.
Thus, there has been a need for a lower profile helmet, that is,
one which is not bulky but lays close to the head, with a minimum
number of straps and supports to avoid the possibility of the
helmet being grasped during the wrestling activity and particularly
eliminating the problems caused by forehead straps which have been
required in the past in order to keep the relatively bulky helmets
on the wearer's head and prevent relative movement therewith.
SUMMARY OF INVENTION
The invention herein contemplates forming a wrestling helmet out of
two guards or parts, each identically formed, but mirror images,
made of thin, relatively stiff but somewhat flexible plastic
material. Each of the guards are roughly inverted triangular in
shape with outwardly bulged ear-receiving cup portions surrounded
by flanges which abut the head around the ears and with each having
an integral upper strap half and rear strap half, the two
corresponding strap halves being adjustably interconnected for size
adjustment. The lower corners of the guards are interconnected by a
chinstrap, preferably utilizing a chin cup of the type disclosed in
my prior application, Ser. No. 878,159 filed Nov. 19, 1969.
Preferably, the chinstrap is connected by snap fasteners to the
guard halves with the fasteners located in recessed portions or
sockets so as to avoid catching or grasping unintentionally. The
ear receiving cups are provided with a padding which protects the
ears against blows and in addition covers and protects the opposite
ends of the chinstrap.
Broadly, the invention herein contemplates a three strap connection
for the approximately triangular shaped guards, with one strap
being located around the base of the skull, the second over the top
of the head but rearwardly of the forehead and the third along the
point of the wearer's chin. With this type of connection, the
helmet is tightly held in place, resisting twisting, and moreover
there are no exposed portions to grasp during the wrestling
activity.
Thus, an object of this invention is to provide a low profile,
nonbulky ear protecting helmet out of thin sheet material, with the
three-strap connection to the head and particularly with the
avoidance of a strap across the forehead, and with protective
padding for the ears to avoid injury due to blows thereto.
These and other objects and advantages of this invention will
become apparent upon reading the following description, of which
the attached drawings form a part.

DETAILED DESCRIPTION
FIG. 1 illustrates a wrestling helmet 10 formed of two identical
but mirror image, roughly inverted triangular-shaped guards 11,
each having outwardly bowed ear cups 12 surrounded by marginal
flanges 13.
The guards are each made out of thin, relatively stiff but somewhat
flexible sheet plastic, such as a suitable polyvinyl or
polyethylene material which resiliently flexes but which remains
relatively stiff and self-sustaining in the absence of
pressure.
Integral with the upper corners of the guards are upper strap
members 15 and rear strap members 16, provided with either rows of
holes 17 or male snap fastener halves 18 so that the corresponding
pairs of upper and rear strap members may be fastened together by
snap fastening the snap fastener halves into preselected holes for
size adjustment to thereby provide an adjustable rear strap 19 and
an upper strap 20.
The rear strap passes around the rear of the head, at the base of
the skull, and the upper strap goes over the upper portion of the
head, rearwardly of the forehead.
To protect against accidental disengagement of the snap fastener
halves 18 from the respective holes 17, thin, flat, tubular sleeves
21 and 22 respectively may be closely and slidably fitted over the
upper and rear straps to cover and protect the snap fastener halves
as shown in FIG. 2.
The lower portion of the ear cups 12 are depressed to form
depressed sockets 24 whose bases are coplanar with the guards'
marginal flanges 13. Above each socket is a depressed downwardly
opening short groove 25 provided with a slot 26 in its base. The
purpose of this construction will be described later.
In addition, a hole 27 is formed in the base of each socket (see
FIG. 3).
Each ear cup is provided with a pad 28 to protect against impact.
Each pad is formed of a pair of thin sheets 29 of flexible plastic
material, between which is positioned a thick, resilient foam pad
or sheet 30. The thin sheets are squeezed together and heat sealed
along the pad peripheral edge 31 and in addition are squeezed
together and heat sealed along a continuous inner line 32, spaced
inwardly of the peripheral edge to thereby form an outer padding
bulge 33 and an inner central padding portion 34.
Transverse seal lines 35 are also formed by squeezing together the
outer sheets 29 and heat sealing them at spaced lines extending
between the peripheral edge 31 and inner line 32. Darts or notches
36 are provided in the edge along these transverse seal lines
35.
In addition, lower transverse seal lines 37 are formed in the same
manner (see FIG. 7).
A number of holes 38 are pierced through the pad and the edges
defining the holes are squeezed together and heat sealed to form
countersinks 39 on each of the opposite faces of the pad.
Preferably, the heat sealing is accomplished by squeezing the
sheets 29 towards each other so that they are joined in a plane
centrally located between the two opposite faces of the pad so that
the pad is thereby reversible with either face being suitable for
facing against the wearer's ear.
The pads are positioned within the ear cups 12 and are so sized as
to not overlap or cover the marginal flange 13 which thereby
contacts the wearer's head for better gripping against the
head.
To fasten the pads to the cups, each cup is provided with holes 40
corresponding in location to the holes 38 in the pads and the sheet
area around the holes 40 are countersunk to form inwardly,
conically shaped depressions 41.
Rivets 42 are inserted through the aligned holes 38 and 40 and
their heads are recessed in the respective countersinks.
At the lower corners of the guards, conventional snap fastener
halves 45 are mounted by means of stud or rivet head portions 46
formed thereon and extending through the holes 27 and through lower
holes 47 in the adjacent pad (see FIG. 5).
As can be seen, the pad is divided into a number of bulged or
puffed sections by the heat-sealing line and each of these sections
is ventilated by one or more air holes 48.
The lower corners of the guards are interconnected by a chinstrap
50, preferably also made of plastic material similar to or
identical to that used for the guards. A snap fastener half 51 is
secured to one end of the chinstrap (see FIG. 5) and a slidable
buckle 52, having a snap fastener half 53 is slidably mounted upon
the opposite end of the strap (see FIG. 6). When the respective
snap fastener halves are joined, they are substantially recessed
below the outermost surface of the guards to avoid accidental
grasping or disengagement.
To insure against accidental disengagement even further, the free
opposite ends 54 and 55 respectively of the chinstrap are tucked
into the slots 26 formed in the grooves 25.
Preferably, the chinstrap should pass around and be engaged with
the point of the wearer's chin. Thus, preferably a chin cup 56, as
disclosed in my above-mentioned application for patent, may be
used, this being in the form of a thin plastic cup having slots 57
at its opposite ends for receiving the strap and with the strap 50
preferably being slit along its length and between its opposite
ends so that the slit formed sections 58 are arranged at the
horizontal edges of the cup.
In operation, the wearer unsnaps the snap fastener half 51, places
the helmet upon his head in the manner illustrated in FIG. 1, and
then replaces the snap fastener. Adjustments as to size may be made
by adjusting the position of the buckle 52 and adjusting the upper
and rear strap lengths by moving the snap fastener halves into
preselected holes to give the correct strap length.
As can be seen, the helmet here closely conforms to the wearer's
head and being made of thin plastic sheet material, without any
exposed graspable surfaces or edges, is almost impossible to
dislodge or twist during the strenuous wrestling activities. The
plastic sheet material is relatively slippery to the touch so that
there is low friction and therefore no great danger of the helmet
frictionally holding on to any adjacent object like the floor mat
or the opponent's clothing or the like.
