Description
BACKGROUND OF THE INVENTION
This invention relates in general to protective equipment and more
particularly to helmets.
Insofar as sporting activities are concerned ice hockey ranks as
one of the more hazardous, and this may be attributed to a number
of related factors. For example, the ice surface on which ice
hockey is played is hard and is difficult to maintain an upright
position on if one's balance or footing is disturbed. Moreover, the
game involves considerable body contact in the form of checking
which on occasion can cause a player to loose his footing and fall
to the ice. The checking can also send a player at high speeds into
the sideboards surrounding the rink. Furthermore the puck is
propelled at high speeds across the rink by sticks which are often
swung with considerable force in close proximity to other players.
The cranium is a particularly vulnerable portion of the body and
when struck in the proper place and with sufficient force, the
body's nervous system can be permanently injured. Since the cranium
and likewise the nervous system are susceptible to injury during
falls to the ice and crashes into the sideboards or by high-speed
pucks or the sticks which propel them, it is indeed important to
protect the cranium during the course of a hockey match.
Heretofore, helmets have been devised for protecting the skulls of
hockey players, and some of these helmets are adjustable to
accommodate varying head sizes. However, the range of adjustment on
such helmets is quite limited and thus the elements fit only a few
head sizes properly. Moreover, many helmets of current manufacture
are cumbersome and become uncomfortable after a short time in
use.
SUMMARY OF THE INVENTION
One of the principal objects of the present invention is to provide
a protective helmet which may be adjusted to fit a wide range of
head sizes. Another object is to provide a helmet of the type
stated which comfortably fits the user's head. A further object is
to provide a helmet which is light in weight and affords ample
ventilation to the scalp for dissipating perspiration generated
during vigorous activity. An additional object is to provide a
protective helmet which can withstand forces of extremely large
magnitude. Still another object is to provide a helmet of the type
stated which is ideally suited for use by ice hockey players. These
and other objects and advantages will become apparent
hereinafter.
The present invention is embodied in a helmet including a backpiece
and crownpiece. The former extends from the vicinity of the
wearer's temples backwardly around the back of the wearer's head,
while the latter has a foreportion extending across the wearer's
forehead and upper protective means extending from the foreportion
generally over the wearer's skull. The crownpiece is attached to
the backpiece at the lateral ends of the foreportion and at the
rear end of the upper protective means. The invention also consists
in the parts and in the arrangements and combinations of parts
hereinafter described and claimed.

DETAILED DESCRIPTION
Referring now to the drawings, 2 designates a protective helmet
which is designed primarily for use by those who participate in ice
hockey matches. Broadly speaking, the helmet 2 includes a
crownpiece 4 and a backpiece 6 which are formed from a relatively
rigid material having a limited amount of flexibility. Both have
padded interior surfaces. When connected together the backpiece 6
and crownpiece 4 form a skull cavity which fits the user's head and
more particularly his cranium. The means for attaching the
crownpiece 4 to the backpiece permits adjustment of one relative to
the other so that both the depth of and the the length of the skull
cavity can be altered.
More specifically, the backpiece 6 is preferably molded from
polyethylene plastic having a thickness of approximately one-eighth
inch. The backpiece 6 extends (FIGS. 1, 3 and 6) from the wearer's
temples backwardly around the entire back of his head. It has a
generally horizontal upper margin 10 which is located below the top
or crown of the wearer's cranium, and a lower margin 12 which along
the back of the wearer's head is also horizontal and is located
above the upper end of the wearer's neck. Along the sides of the
backpiece 6 the lower margins 12 curve upwardly and then downwardly
again in the provision of ear cutouts 14. Forwardly from the
cutouts 14 the backpiece 6 has temple sections 16 which extend
downwardly along the wearer's temples and terminate close to the
upper ends of the cheek bones.
Near the forward ends of its upper margin 10, the backpiece 6 is
provided with a plurality of closely spaced apertures 18 (FIGS. 5
and 6) which extend downwardly and rearwardly through the temple
sections 16 in lines oblique to the horizontal upper margin 10. The
rearmost aperture 18 in each line is disposed generally above and
slightly forwardly from the center of the ear cutout 14 on the
corresponding side of the backpiece 6, while the forwardmost
aperture 18 is located adjacent to the upper margin 10 at the point
where that margin turns downwardly to form the corresponding temple
section 16. Similarly, at the very center of the backpiece 6, that
is at its rearmost portion thereof, another line of spaced
apertures 20 (FIGS. 2, 5 and 6) extends vertically between the
horizontal upper margin 10 and the horizontal segment of the lower
margin 12.
The inside face of the portion of the backpiece 6 located above the
horizontal segment of the lower margin 12, which is the portion
extending across the back of the head, has several strips of
padding 22 (FIGS. 5 and 6) attached to it. The strips of padding 22
extend vertically and the two center strips are spaced apart at the
apertures 20 so that the entire line of apertures 20 is exposed
between them. Beyond the strips of padding 22 triangularly shaped
side pads 24 are attached to the innerface of the backpiece 6. The
forward margins of each side pad 24 follow the rear margin of the
adjacent ear cutout 14, and where the margin of that cutout 14
turns forwardly and downwardly the forward margin of the pad 24
continues upwardly along the rear side of the adjacent line of
apertures 18. The inner faces of the temple section 16 also have
temple pads 26 secured to them and the upper margins of those pads
26 are located below the lines of apertures 18. Consequently, the
apertures 18 on each side of the backpiece 6 are exposed between
the pads 24 and 26.
The padding 22 and the pads 24 and 26 are preferably formed from a
foamed vinyl composition such as polyvinyl chloride and are
attached to the inner face of the backpiece 6 by a suitable
adhesive.
The crownpiece 4 similarly is approximately one-eighth inch thick
and preferably molded from polyethylene plastic. It includes a
foreportion 30 which extends across and shields the
wearer'forehead. Beyond the forehead the foreportion 30 merges into
a pair of rearwardly extending wings 32 (FIGS. 1, 4 and 6) which
extend across the forward end of the backpiece 6, overlying the
upper end of the temple sections 16 thereon. Each wing 32 is
secured to the backpiece 6 it overlies by a bolt 34 which extends
through one of the apertures 18. As will be noted hereinafter the
particular aperture 18 selected depends on the size of the user's
head. Each bolt 34 threads into a nut 36 positioned against the
inner face of the temple section 16 on backpiece 6.
In addition to the foreportion 30 the crownpiece 4 includes upper
protective means in the form of a pair of rearwardly extending
bands 38 (FIG. 4 which extend across the wearer's cranium from the
foreportion 30 to the center or rear of the backpiece 6. In
particular, the bands 38 at their forward ends merge into the
foreportion 30 and in effect form an integral rearward continuation
thereof. As the bands 38 extend rearwardly they converge and at the
rear of the skull they merge into a common connecting segment 40
(FIG. 3) which extends downwardly across the rearwardly presented
face of the back piece 6. The connecting segment 40 is attached to
the backpiece 6 above the horizontal portion of the lower margin 12
thereon by means of a bolt 42 which extends through that segment
and into one of the vertically spaced apertures 20 in the backpiece
6. Again the particular aperture 20 selected depends on the size of
the wearer's head. The bolt 42 threads into a nut 44 positioned
behind the selected aperture 20 and against the inwardly presented
face of the backpiece 6. The bands 38 are reinforced by
longitudinally extending ribs 46 formed integral thereto.
The inner face of the foreportion 30 has a series of vertically
extending pads 48 (FIG. 5) attached to it, likewise the inner or
downwardly presented surfaces on the bands 38 have pads 50 secured
to them, and those pads terminate prior to the connecting segment
40. The pads 48 and 50 are also preferably formed from a foamed
vinyl composition and are adhesively secured to the crownpiece
4.
Thus, the strips of padding 22, the side pads 24, and the temple
pads 26 on the backpiece 6, and the pads 48 on the crownpiece 4
form a row of padding which completely surrounds and absorbs blows
directed against the side of the wearer's head, whereas the pads 50
on the crownpiece 4 extend over and absorb blows directed against
the top of the head.
The helmet 2 is held in place by a chin strap 52 (shown only in
FIG. 1) which includes two segments each of which is Y-shaped. Each
segment is furthermore attached to one side of the backpiece 6
adjacent to each end of the ear cutout 14 therein.
The helmet 2 fits a wide range of head sizes and is adjusted to the
proper size by a trial or error procedure. In particular, the
helmet 2 is shipped in assembled form with the bolts 34 extending
through corresponding apertures 18 in the two oblique lines of
apertures 18, and with the bolt 42 positioned in one of the
apertures 20. If the skull cavity in helmet 2 is too small, it may
be enlarged by placing the bolts 34 in apertures 18 located further
forwardly and the bolt 42 in a higher aperture 20. Conversely, to
decrease the size of the cavity 8 and make the helmet 2 suitable
for smaller head sizes the bolts 34 should be placed in apertures
18 located further to the rear in the backpiece 6 and the bolt 42
should be inserted in a lower aperture 20.
It is possible to provide a modified helmet 60 (FIG. 7) which is
very similar to the helmet 2. The helmet 60 includes a crownpiece
62 and a backpiece 64, the latter of which is practically identical
to the backpiece 6. However, the crownpiece 4, while having a
foreportion 66 and bands 68 extending rearwardly therefrom to a
common connecting segment 70, has wings 72 formed by convex and
concave margins which intersect at a point instead of generally
parallel margins which intersect at an arc as is true of the wings
32 on the helmet 2. Moreover, the lower margin of the foreportion
66 extends across the forehead in an upwardly directed arch and not
horizontally across it as does the lower margin on the foreportion
30. The inwardly presented surfaces of the crownpiece 62 and
backpiece 64 have padding attached to them.
In the helmet 60 the wings 72 have the shape of the distinctive
Michigan-type wing. The helmet 60 is otherwise the same as the
helmet 62 and serves the same purpose.
The helmets 2 and 60 because of the wide range of adjustment
provided need only be manufactured and warehoused in a single size.
They are furthermore light in weight and each is easy to put on and
remove. The void between the various pads is thin and likewise the
spaces between and to the side of the bands 38 and 68 afford
considerable ventilation. Thus, the helmets 2 and 60 are ideally
suited for use by ice hockey players.
This invention is intended to cover all changes and modifications
of the example of the invention herein chosen for purposes of the
disclosure which do not constitute departures from the spirit and
scope of the invention.
