Protective glove
Abstract
A protective glove intended for use by law enforcement officers
and the like having in its preferred embodiment a thumbless
hand-shaped leather outer glove side, a similarly hand-shaped
leather inner glove side having a thumb, the two glove sides being
sewn together along their aligned edges (using a joinder strip in
the finger areas) to form a hollow leather glove shell. A
protective insert sandwich comprising an outer layer of lead-filled
vinyl, two intermediate layers of metal wire mesh and two inner
layers of foam cushion is positioned next to the outer glove side.
A hollow inner lining of smooth fabric is inserted into the hollow
leather glove shell between the two foam cushion layers and the
inner glove side. The resulting glove provides considerable
protection against heavy blows, sharp objects and other instruments
which would normally damage the wearer's hand and fingers. The
glove also has considerable weight which enables the wearer to
strike an assailant with an effective blow.

Description
BACKGROUND OF THE INVENTION
In the past, there have been many developments in the field of
protective clothing for military and law enforcement personnel.
Specifically, armored garments have gained widespread acceptance.
Some portions of the body are easier to protect than others. Those
body portions which are not involved in much movement (e.g. the
torso) are suited to being protected with relatively heavy and
inflexible armored garments. On the other hand, those body portions
which are involved in substantial movement (e.g. the arms and legs)
require considerably lighter and more flexible armored garments.
The heavier the protective garment, the greater its protective
capability, and the more it hinders the mobility of the wearer.
Obviously, the design of any protective garment involves a
compromise between levels of protection and mobility.
This invention relates to a protective glove which is specifically
designed for use by police officers involved in riot control
activities. Prior protective gloves have included layers of fabric
and/or metal padding which are usually sewn between the outer and
inner shells of the glove. These gloves have typically been bulky,
heavy, stiff and awkward to use, with the result that they seldom
were used. Also, despite their weight, most of these gloves
provided inadequate protection against sharp objects such as knives
or ice picks. Examples of such prior gloves are shown in U.S. Pat.
Nos. 2,657,391; 2,737,597; 2,864,091; 3,108,285; and 3,258,782.
It is an object of this invention to provide a protective glove
which has both offensive and defensive capabilities. By offensive,
it is meant a glove which has sufficient weight in a suitable
location to permit the wearer to strike his assailant with a heavy
blow. By defensive, it is meant a glove which has sufficient armor
in suitable locations to protect the wearer from injury from a wide
variety of sharp and heavy weapons.
It is another object of this invention to provide a protective
glove which is comfortable to wear, which is relatively flexible,
which is relatively light-weight, which is similar in outward
appearance to a conventional glove, which is relatively inexpensive
to manufacture, which will retain its shape after extended use, and
which, if cut by a sharp knife, will not fall apart or permit its
armored portions to become detached from the rest of the glove.
SUMMARY OF THE INVENTION
The protective glove of this invention has a protective armored
insert which protects the entire outer or back portion of the hand
as well as the backs of the fingers. The glove is quite flexible
and has the general appearance of a conventional glove. The weight
of the protective insert is evenly distributed across the back
portion of the hand and is fixed in that even distribution. The
glove has a hollow outer shell and a hollow inner lining in the
manner of a conventional glove. A protective insert is encapsulated
between the two hollow elements so as to protect the outer portions
of the hand and fingers. The protective insert includes a
metal-filled plastic layer, two wire mesh layers and two foam
cushion layers. These layers are loosely held together and several
layers are sewn to the outer glove side at the cuff. Therefore, the
protective insert has considerable freedom to slide relative to the
outer glove shell when the wearer's hand is made into a fist. This
feature greatly increases the glove's flexibility.
DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of the protective glove of this
invention; and
FIG. 2 is an exploded view of the various layers forming the
protective glove of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 shows the complete glove 10 which, in all outward respects,
closely resembles a conventional glove. Glove 10 can be made in
various lengths extending to the wrist or extending as much as
eight inches above the wrist.
Glove 10 has a thumb-less hand-shaped outer glove side 12 and a
correspondingly shaped inner glove side 14. Both glove sides are
preferably made of leather or other animal hide, but can also be
made of other natural or synthetic materials. The inner glove side
14 is sewn to a thumb 15 and the fingers of the two glove sides are
sewn to a joinder strip 16 in the conventional square or box finger
construction with all sewn seams hidden by assembling and stitching
the glove inside out and then turning the glove outside in to
conceal and protect the threads during use. The box finger
construction is preferred because it provides excellent finger
flexibility and also provides considerable space for the
encapsulating of the protective armored insert next to the flat
outer glove side 12. An elastic strip is sewn to the inner surface
of inner glove side 14 at the cuff to keep the cuff snug. FIG. 1
shows the completed sewn hollow leather outer glove shell.
It will be understood that other glove constructions could be used.
For example, the joinder strip 16 could be extended around the
entire glove. Also, the outer glove shell could be made of
synthetic material and molded in one piece. The important point is
that a hollow outer glove shell is required.
A hollow inner lining 18, which is shaped like the hollow outer
glove shell, but which is slightly smaller than the outer shell, is
inserted into the outer hollow outer glove shell and is affixed
thereto by a stitched hem 20. FIG. 2 shows the inner portion of the
lining (and its sewn thumb) which is positioned against the inner
glove side 14, and also shows the outer portion of the lining which
is positioned against the protective insert. When assembled, the
inner and outer portions of the inner lining 18 are sewn together
around their aligned peripheries (with the addition of a joinder
strip and a thumb), or the lining could alternatively be a single
piece.
Preferably, inner lining 18 is made of a sueded nylon fabric which
is pleasant to touch and which permits ease of hand insertion and
removal. Obviously, other fabrics could be substituted.
What has thus far been described is a conventional glove having an
outer shell and an inner lining affixed thereto. What will
hereafter be described is the protective armored insert which
changes the character of the glove to one which has offensive and
defensive capabilities.
The protective insert comprises a number of layers including at
least three different types of material which serve three different
purposes. FIG. 2 shows the preferred embodiment of the protective
insert which includes five material layers.
The layer which is positioned directly against outer glove side 12
is a metal-containing plastic material layer 22. Layer 22 is shaped
like a thumb-less hand and extends approximately eleven inches from
the fingertip portion of the outer glove shell up to the cuff
portion of the shell. Therefore, layer 22 protects the entire back
of the fingers and the hand. Layer 22 is flat, relatively flexible
and has a solid sheet form. Preferably, layer 22 is a lead
particle-filled vinyl plastisol elastomer which has even heavy
weight distribution, great structural and tensile strength, high
density, great tear strength, and great resilience.
Layer 22 spreads, absorbs and protects against impacts and shocking
blows by yielding, absorbing, and then elastically returning to its
original shape. It is also very tough and resists penetration by
sharp objects. When the metal particles used are lead, the glove
has the added feature of not transmitting ionizing radiation to the
wearer's hand. This could be useful in the event a suspect were
being inspected in an X-ray apparatus. Also, of course, lead is a
very heavy metal and has considerable shocking power when the glove
is used as an offensive weapon.
Positioned next to the metal-filled plastic layer 22 is the top
layer 24 of metal wire mesh material. This wire mesh layer is
generally rectangular and is approximately six inches long. Layer
24 extends from the upper finger portion of the glove up to the
cuff portion. Therefore, it protects the back of the hand against
the penetration and/or cutting action of a knife or other sharp
instrument. It also has a cushioning effect. Layer 24 is flat, and
is quite flexible along its longitudinal axis. Preferably, layer 24
is a knitted, stainless steel wire mesh which has high strength and
has high resistance to cutting or tearing.
Positioned next to top wire mesh layer 24 is an essentially
identical bottom layer 26 of metal wire mesh material. Preferably,
the two wire mesh layers are formed from a cylinder which is
flattened into a rectangular two layered sandwich. FIG. 2 shows
this flattened cylinder, and top layer 24 is broken away in the
drawing to better illustrate the underlying bottom layer 26.
Positioned next to the bottom metal wire mesh layer 26 is the top
cushioning material layer 28. This cushioning layer, like the wire
mesh layers, is rectangular. Top cushioning layer 28 is
approximately seven inches long and extends from the upper finger
portion of the glove to the cuff portion slightly beyond the wire
mesh layers. Therefore, cushioning layer 28 cushions the back of
the hand against shocking blows and also is designed to cushion and
to withstand the abrasive nature of the wire mesh material against
which it bears.
Top cushioning material layer 28 is flat, flexible, and has a sheet
form. Preferably, layer 28 is composed of a number of thin sheets
of semi-rigid ethyl cellulose closed cell foam which are adhered
together and which strongly resists compression collapse.
Positioned next to the top cushioning layer 28 is the bottom
cushioning material layer 30. This cushioning layer is similar to
top cushioning layer 28 except that it preferably extends
approximately eleven inches from the fingertip portion of the outer
glove shell up to the cuff portion.
The inner lining 18 is fastened at its fingertips to both bottom
cushioning layer 30 and the metal-filled plastic material layer 22.
This helps to prevent the inner lining from being pulled out of the
glove shell when the wearer's hand is removed from the glove. The
plastic material layer 22, the two cushioning layers 28 and 30 and
the outer (i.e. upper) portion of inner lining 18 are inserted
under the turned back hem 20 of outer glove side 12, and all of the
foregoing are stitched together along the hem.
The five layers 22, 24, 26, 28 and 30 form the preferred embodiment
of the protective insert which effectively protects the outside of
the fingers and hand of the wearer. These five layers are not all
fastened to each other and are stitched to outer glove side 12 only
at the cuff which prevents lateral displacement while allowing
longitudinal sliding of the protective insert relative to the outer
glove side 12. This feature permits the wearer to more easily make
a fist or grip an object despite the presence of the protective
insert next to the outer glove side.
It will be appreciated that a fully functional protective glove can
be fabricated with a protective insert containing three layers 22,
24 and 30. However, the two additional layers 26 and 28 greatly
increase effectiveness of the protective glove.
In constructing the preferred embodiment of the glove 10, the first
step is to form the outer glove shell by the reverse stitching
method described previously. Simultaneously, the inner lining 18 is
formed either by the reverse stitching method or by a simple sewing
operation.
At the same time, the protective insert is formed and preassembled.
The wire mesh cylinder is flattened to form mesh layers 24 and 26.
The two cushioning layers 28 and 30 are placed together and are
positioned against the bottom wire mesh layer 26. This preassembles
four of the five layers.
The lead-filled vinyl layer 22 is formed by first mixing very fine
particle size lead powder with semi-viscous vinyl plastisol
elastomer. After achieving a thorough mixture, the liquid is cast
to shape in a heated mold, or is cast into sheet form in a heated
mold, or calendered, and is then die cut to shape. The heating
produces a rubber-like elastomeric solid product. After cooling,
the lead-filled vinyl layer 22 is positioned next to the top wire
mesh layer 24.
The next step is to attach together the aligned fingertips of the
inner lining 18, the bottom cushioning layer 30 and, optionally,
the lead-filled vinyl layer 22. Then, the assembler places his hand
into inner lining 18 and inserts the inner lining and the five
layer protective insert into the hollow outer glove shell so that
the protective insert is located between the inner lining and the
outer glove side 12.
Finally, the cuff edges of the hollow outer shell are folded back
over the edges of the hollow inner lining 18, the cushioning layers
28 and 30, and vinyl layer 22, to form a hem 20 which is stitched
around the cuff portion. This stitching fastens these layers to the
cuff and also encapsulates the wire mesh layers 24 and 26 between
the upper finger portion of the hollow outer glove shell and the
cuff portion thereof. The glove is thus completely assembled.
It will now be seen that the preferred embodiment has many
advantages over prior art gloves. It protects the entire backs of
the fingers as well as the back of the hand, while still providing
the wearer with great flexibility of hand and finger movement. This
is a considerable achievement. Also, the glove is quite
conventional in appearance because of the flatness of the
protective insert. It has a desired heavy weight, but the weight is
so evenly distributed that it is not burdensome to the wearer.
The glove provides significant protection against heavy blows,
against pointed sharp instruments, against knives, against hot or
cold objects, and against ionizing radiation. The protective insert
is very dense and is not displaceable within the glove despite the
occurrence of repeated heavy blows. Even if the outer glove side is
cut, the protective insert will not likely become detached and
cannot disintegrate.
The glove has excellent balance and feel, is extremely durable, and
can be manufactured relatively easily at a relatively low cost. The
lead-filled vinyl layer 22 is particularly important because it
provides the offensive capability as well as the defensive
capability to the wearer. It also protects the wearer's fingers
(because of its intricate shape) as well as his hand, yet does not
impede the mobility of the wearer's hand and finger movement. The
glove is highly resistant to virtually all types of hand weapon
attacks and is capable of being used offensively with great effect.
It is a superior protective glove to all prior gloves known to the
inventor.
The above description obviously suggests many possible variations
and modifications of this invention which would not depart from its
spirit and scope. It should be understood, therefore, that the
invention is not limited in its application to the details of
structure specifically described or illustrated and that within the
scope of the appended claims, it may be practiced otherwise than as
specifically described or illustrated.
