ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to stabproof and bulletproof jackets. In particular, the present invention relates to a stabproof and bulletproof panel, which is constructed in such a way that a plurality of stabproof panels for protecting the body of a user from bladed weapons, such as a knife, a machete, a stiletto and switch-blade, are attached to the front surface of a bulletproof panel for protecting the body from the bullets of firearms, such as a pistol and a rifle, thereby allowing the panel to have both stabproof and bulletproof functions.
2. Description of the Prior Art
In general, a bulletproof jacket for protecting the body from bullets is basically comprised of a garment, a bulletproof panel, and a panel covering. In general, a stabproof jacket is basically comprised of a garment, a stabproof panel, and a plate covering. The bulletproof panel, which is the principal element of a bulletproof jacket, is generally manufactured in conformity with a standard (NIJ STANDARD-0101.03) for testing bulletproof jackets established by the National Institute of Justice (NIJ), U.S. Department of Justice. It is generally tested by a test organization affiliated with the NIJ, such as H. P. White Laboratory Inc. to determine whether a bulletproof panel has been manufactured in conformity with these standards or not.
A variety of stabproof jackets and a variety of stoneproof jackets are manufactured to protect the body from bladed weapons, such as a knife, a machete, a stiletto and switch-blade. Korean Utility Model Publication No. 91-5180 discloses a stoneproof vest, in which many folds of carbon fiber cloths are interposed between outer and inner covers, and a protective panel formed by bonding two protective fabrics
10
to the upper and lower surfaces of a rubber plate
11
or fiber reinforced plastic plate is inserted into a space between each neighboring carbon fiber cloths. This stoneproof vest is easily manufactured, is easily bent, and allows a wearer to be moved. However, this stoneproof vest causes the movement of the body to be inconvenient owing to the weight of rubber plates, and this inconvenience is increased owing to the weight of protective fabrics attached to the rubber plates. Korean Utility Model Unexamined Publication No. 91-009505, as shown in
FIG. 2
, discloses a protective vest, in which a vest body “A” having neck and arm openings
23
and
24
and reinforcing strips
25
is formed by two protective plates
21
and
22
, a woven stretch fabric is attached to the lower end of the vest body “A”, and a plurality of protective pieces are attached to the woven stretch fabric while being overlapped at their edges. The prior art protective vest can protect the body of a user from the sharp blade of a bladed weapon when the sharp blade is brought into contact with the large protective plates
21
and
22
of the vest body “A”. However, the small protective pieces
27
are attached to the woven stretch fabric
26
, so two neighboring protective pieces
27
are widened to form a space therebetween and the sharp blade slips on the protective pieces
27
into the space when the sharp blade is brought into contact with the small protective pieces
27
, thereby allowing the shape blade to pierce into the body and the body to be damaged. Additionally, when the sharp blade is upwardly brought into contact with the stretch fabric, the sharp blade pierces into the body and seriously damages the body while the small protective pieces
27
are raised up.
There are disclosed a variety of stabproof panels for protecting the body from the blade of a bladed weapon and a variety of bulletproof panels for protecting the body from bullets fired from a firearm. The stabproof panels can protect the body from the sharp-edged blade of a bladed weapon, but cannot protect the body from bullets rapidly projected from a firearm. On the other hand, the bulletproof panels can protect the body from bullets rapidly projected from a firearm, but cannot protect the body from the sharp-edged blade of a bladed weapon and. However, there is not disclosed a stabproof and bulletproof jacket for both protecting the body from both the sharp-edged blade of a bladed weapon and bullets rapidly projected from a firearm. Accordingly, one of the stabproof jacket and the bulletproof jacket is utilized separately from the other in accordance with circumstances or purposes. As a result, when a firearm and a bladed weapon are simultaneously used, its user is jeopardized while performing his duty.
In order to solve the problems, the assignee of the present patent application filed Korean Pat. Appln. No. 1999-0007174. This patent application discloses a bulletproof panel for bulletproof jackets, which is manufactured in conformity with a standard (NIJ STANDARD-0101.03) for testing bulletproof jackets established by the NIJ, U.S. Department of Justice which is certified by a test organization affiliated with the NIJ, such as H. P. White Factory Inc. as shown in table 1. As shown in
FIG. 4
, the assignee of the present patent application discloses a bulletproof panel for bulletproof jackets, which is comprised of a front plate
45
, a plurality of high density polyethylene films
44
stacked with one on top of another for dispersing impact energy, and a rear plate
46
formed by sewing together a plurality of aromatic polyamide woven fabrics
46
for minimizing frictional heat and deformation, the front plate
45
consisting of a plurality of aromatic polyamide woven fabrics
41
, a felt
50
formed by forcibly inserting thin aromatic polyamide fibers or high density polyethylene fibers and a shock-absorbing member
51
into a scrim
52
woven in the form of a net using aromatic polyamide fibers or high density polyethylene yarn, and a plurality of aromatic polyamide woven fabrics
43
.
