LAMINATED HELMET
Abstract
The specification discloses a head covering in the form of a
helmet of unique construction adapted for wear indoors by persons
of either sex during leisure time or while sleeping. The helmet is
multi-layered, with an outer layer of lambs wool, long-haired fur
or other similar heat insulating material and an inner layer of
woven fabric. The helmet is constructed so as to be supported at
each side on the bridge of the wearer's ears and in front on the
wearer's brow so as to provide an air space between the crown of
the wearer's head and the inside of the helmet. The rear portion of
the helmet has an essentially inverted V-shaped opening for
ventilation of the space above the wearer's head within the helmet
by ambient air. The two extremities of the rear portion of the
helmet are held snugly to the back of the wearer's neck by an
adjustable strap of elastic material connecting them. Additional
tie strings sewn to the rear extremities of the helmet serve, when
tied, to insure clearance between the rear portion of the helmet
and the head of the wearer, notwithstanding variations in the
wearer's head size.

Claims
What I claim is:
1. A helmet comprising a relatively stiff crown portion and a rear
portion conforming generally to the contour of the human head and
consisting of laminate material, the crown portion having a frontal
edge adapted to seat low on the brow of the wearer and to arch
forwardly away therefrom and having at each side an ear bridge -
supported side edge that extends in a substantially straight
horizontal line backwardly from the frontal edge, said crown having
a vertical height such that the ear bridge-supported side edges are
adapted to support the crown portion in an elevated position
providing a space within the crown portion above the top of the
head of the wearer, the said rear portion having a generally
inverted V-opening extending into said crown portion via which
ambient air may enter and circulate within the said space within
said crown portion while on the head of a wearer, and tensioning
means extending across said V-shaped opening and adapted to rest on
the back of the neck of the wearer to secure the helmet in
position.
2. A helmet according to claim 1, wherein said laminate material
comprises an outer layer selected from a group of materials
consisting of lambs wool, fur and leather and an inner layer of
woven fabric.
3. A helmet according to claim 1, wherein said laminate material
comprises an outer layer of leather, an inner layer of woven fabric
and an intermediate layer of foam plastic.
Description
This invention relates to a head covering in the form of a helmet
adapted especially for indoor wear by persons of either sex during
leisure time or while sleeping.
It is believed by some that a warm moist environment is conducive
to stimulation of hair growth on the human body. That belief is
enhanced by the apparent fact that peoples inhabiting warm humid
areas in the world commonly have a more luxuriant growth of hair,
especially on their heads, than do people inhabiting temperature or
cold areas.
On the premise, therefore, that production of a warm and moist
environment for humans occupying temperature or cold areas in the
world would be beneficial for growth of hair, it is an object of
this invention to provide a helmet uniquely constructed to enable
persons so inclined to realize these conditions in a simple
inexpensive manner and with little or no inconvenience to
themselves.
It is an additional object of the invention to provide a helmet of
the aforesaid type constructed and designed for use by persons of
different head sizes yet contacting the brow and sides of the head
in a manner to provide for ventilation of a space between the head
of the wearer and the helmet through an opening at the rear of the
helmet.
The above objects, and other objects of the invention which will
become apparent in the subsequent description thereof, are attained
by the embodiments of the invention depicted in the accompanying
drawings, wherein:
FIG. 1 is a side view of the head of a person wearing the helmet
constituting the invention, showing in partial section the manner
of application of the helmet to the head of the wearer and details
of construction;
FIG. 2 is a front view, partially in section, showing further
details of construction and design of the helmet shown in FIG.
1;
FIG. 3 is a rear view, showing other details of the helmet,
particularly the rear ventilation opening; and
FIG. 4 is a side view of the head of a person wearing a helmet of
modified construction.
Referring to the drawings, the embodiment of a helmet 10 shown
therein is of multi-layered construction comprising an outer
covering or layer 11 of thick material such as lambs wool or fur
relatively stiff in nature and capable of insulating against
radiation of heat from the head of the wearer, and an inner lining
12 of suitable woven fabric, such as rayon or cotton, sewn or
otherwise secured along the outline or border to the inside of the
layer 11. A modified embodiment, shown in FIG. 4, comprises an
outer covering or layer 13 of leather, plastic or closely woven
fabric, an intermediate layer 14 of porous material such as foam
plastic, foam rubber, hair or vegetable fiber, and a lining 15 of
woven fabric such as cotton. Since the two embodiments are
otherwise similar in construction and design, it will be understood
that further description of the embodiment of FIG. 1 applies also
to the embodiment of FIG. 4.
In general, both embodiments of the helmet conform generally to
contour of the human head, due allowance being made for some
variation in the size of the head. The entire upper portion of the
head including the scalp area of hair growth is surrounded. At the
front of the helmet is a brow contacting portion which is
preferably arched as shown in FIG. 2, the contact line or area on
the brow varying in position from 1/2 to 3/4 of an inch above the
eyebrows of the wearer. At each side of the head, the helmet
outline is substantially a straight line from the brow-contacting
portion so as to rest on the bridge of the ears to the head, the
ears being completely outside the confines of the helmet. By thus
resting on the brow and the ear bridges the helmet is supported so
as to provide a ventilation space 16 between the head of the wearer
and the inside surface of the helmet. The relative stiffness of the
helmet itself serves to retain the crown of the helmet in spaced
relation to the head of the wearer. The amount of the space will
vary from 1/2 to 1 inch depending on the size and contour of the
wearer's head, as well as the amount of hair on the wearer's
scalp.
As will be seen in FIG. 3, the back of the helmet extends
downwardly to approximately the top of the neck of the wearer, and
is provided with an opening 17 which is essentially of inverted
V-shape. The two extremities of the helmet on opposite sides of the
opening 17 are connected by tensioning means such as an adjustable
elastic band 18 which causes the extremity of the helmet to snugly
fit the neck of the wearer. In addition to the elastic band 18,
each of the rear extremities of the helmet may have sewn thereto a
string 19 of suitable material, such as suede, the two strings when
drawn together and tied as shown, assisting in retaining the helmet
in position on the head so as to maintain clearance between the
rear portion of the helmet and the head of the wearer,
notwithstanding differences in physical measurements of the
wearer.
It will be understood therefore, that the opening 17 at the back of
the helmet is held in spaced relation to the back of the head of
the wearer, thereby providing for free flow of ambient air into and
out of the space 16 between the crown of the head of the wearer and
the inside of the helmet. Excessive build-up of heat in the space
16 is thus prevented and an even temperature corresponding
substantially to body temperature is maintained, due to containment
by the helmet of body heat radiated from the scalp.
In use, the helmet may be worn while the wearer is relaxing
indoors, such as when reading or watching television programs. It
may also be worn overnight while the wearer is sleeping, provided
precaution is taken not to lie so as to block the opening 17.
While I have illustrated and described a present preferred
embodiment of the invention, it will be understood the invention
may be otherwise variously practiced within the scope of the
following claims.
