maintained in said raised inoperative position.
Description
BACKGROUND OF THE INVENTION
The present invention relates to a protective face shield primarily
for policemen who in the pursuit of their normal duties are
confronted and fired upon often without warning at close range with
small caliber hand guns. Heretofore, no face shields which can be
readily attached and detached from a helmet have been developed to
afford the wearer the degree of protection to the face and head as
needed.
SUMMARY OF THE INVENTION
Bullet wounds to the face and head are extremely painful and are
often fatal. In order to prevent such injuries a face shield must
stop a lead bullet up to size .38 caliber when fired from a hand
gun at a distance of one foot. The face shield must not shatter as
flying fragments would be dangerous to the eyes and facial tissue.
To be effective the face shield must also provide excellent
visibility in various climatic conditions. In addition, such a face
shield must be readily attachable to and detachable from the
helmet.
Accordingly, it is an object of the present invention to provide a
protective face shield that remains optically clear at all times,
can be quickly attached to or detached from a helmet and most
importantly will stop caliber bullets fired from hand guns at close
range. The shield extends from the forehead portion of the helmet
rearwardly to the side portions of the helmet, depends therefrom to
a position adjacent the chin of the wearer, and consequently
substantially completely covers the wearer's face.
It is another object of the invention to provide a means for
pivoting the face shield upward to a position overlying the top
portion of the helmet so that the face shield is out of the way
when, for example, the wearer wishes to talk to another person.
A still further object of the invention is to provide a face shield
which will withstand and deflect high impact blows from clubs,
bricks, bottles and other similar objects often encountered by law
enforcement officers during a riot.
Other objects will be apparent from the following description taken
in connection with the accompanying drawings, in which:
FIG. 1 is a pictorial exploded view of one embodiment of the bullet
proof shield assembly of this invention and a supporting helmet
therefor;
FIG. 2 is a side elevation view of the helmet of FIG. 1,
illustrating the transparent bullet proof face shield in lowered
operative position substantially completely covering the face of
the wearer;

FIG. 9 is a side elevation of the helmet of FIG. 8 illustrating the
face shield in lowered operative position;
FIG. 10 is a side elevation of the helmet of FIG. 8, illustrating
the face shield in the raised position;
FIG. 11 is a fragmentary sectional view taken along the line 11--11
of FIG. 8; and
FIG. 12 is a fragmentary sectional view taken along the line 12--12
of FIG. 8.
Referring to the drawings, FIG. 1 illustrates a helmet assembly 10
adapted to be worn by a motorcycle patrolman, foot patrolman or the
like, although the invention is not limited thereto.
The helmet 10 per se does not form a part of the present invention,
although it is desirable that it too be of bullet proof
construction so as to further add to the protection of the
wearer.
The transparent bullet proof face shield assembly, indicated
generally at 14, is curved to conform to the general shape of the
forehead portion 13 of the helmet 10. The bullet proof face shield
consists of two transparent plastic panels 26 and 28 (FIG. 7) held
in spaced relationship by a spacer 30 of the same material as the
panels. The panels are preferably formed of a high impact resistant
polycarbonate known as LEXAN. The panels and spacer are joined
together with an adhesive so as to provide a liquid tight dead air
space 27 between the panels. The preformed curved panels 26 and 28
are assembled in a metal mounting frame 24 which is of channel
shape in cross section.
The dead air space 27 between the outer panel 26 and the inner
panel 28 assures a fog free face shield during cold weather.
However, the primary function of the spacer 30 is to provide a
space between the panels into which the outer panel 26 can flex
inwardly upon the initial impact of a bullet. The panel 26 can then
flex back after the bullet has mushroomed upon impact with the
inner panel 28 and thereby trap the spent bullet between the panels
in the event the outer panel is pierced. Mounting brackets 16 are
attached to each side of the bullet proof face shield near the aft
top edges for engagement with corresponding fastening pins 18
mounted on opposite sides of the helmet 10.
In the lowered operative position of the shield 14, the edge frame
24 on the aft edges of the face shield 14 engage generally Z-shaped
brackets 22 (FIGS. 4 and 7) attached to each side of the helmet 10
with friction action so as to remain engaged therewith until
intentionally dislodged.
To position the bullet proof face shield 14 so as to remain in the
raised position illustrated in FIG. 3, the face shield is grasped
at the center lower edge, pivoted upward until the bracket 16 is in
a horizontal position, and then pushed toward the helmet for
brackets 16 to engage the end slots 42 therein with pins 40 which
project from the helmet as shown in FIG. 6.
The face shield 14 is quickly removable from the helmet 10.
Starting with the face shield in the raised position shown in FIG.
3, it is moved straight forward until the pins 18 are at the rear
of the slots 44, and then lifting the face shield straight
upward.
In the modified bullet proof face shield 14a, illustrated in FIGS.
8, 9, 10, 11 and 12, the supporting frame for the spaced panels is
comprised of a steel rod 48 covered with plastisol. Compound curved
outer panel 56, inner panel 58 and spacer 60 are bonded together to
form a liquid tight dead air space 59 between the panels. The
transparent bullet proof face shield is positioned within the steel
frame 48 and secured in place with a shaped thin metal moulding 50
that surrounds the frame 48.
Spring steel clips 52 attached to each side of the helmet retain
the face shield when it is in the lowered operative position.
The modified face shield 14a is mounted on the helmet 10 like the
shield 14 is mounted, as described above.
It is to be understood that while face shields 14 and 14a are shown
with two panels each, it is within the purview of this invention to
incorporate additional panels in the shields.
