Indicating target employing foil sheet
Abstract
A target for firearms comprising a metal foil sheet with a
conventional target pattern printed thereon. The foil may be
mounted in spaced relation to a backup sheet of highly contrasting
color by means of a transparent frame. When struck by a firearm
projectile, a substantially larger-than-projectile-size hole is
produced in the metal foil target, thus revealing an area of the
contrasting backup sheet. The projectile makes only a conventional
size hole in the backup sheet which has congruent target lines
thereon for precise scoring. The point of impact thus appears on
the target as a relatively large area of color which can easily be
seen at target range distances.

0.025 mm thick.
7. The target of claim 1 wherein said backup sheet has a target
pattern thereon, said targer pattern being congruent with said
target pattern on said metal foil sheet.
8. The target of claim 1 wherein said metal foil sheet is about

Description
BACKGROUND
1. Field of the Invention
This invention relates to a firearms target especially suitable for
use with small or hand held firearms. The target provides a high
visibility indication of the point of projectile impact on the
target.
2. Description of the Prior Art
Common firearms targets comprise generally a sheet of paper having
the usual concentric circles and bullseye printed thereon. When
puncture by a speeding bullet, a slightly smaller-than-bullet-sized
hole is produced in the paper sheet. At conventional target range
distances the location of the hole is very difficult to determine
because of its small size and lack of contrast with the rest of the
target. This lack of hole visibility is especially pronounced when
using rounds of small diameter, e.g., 0.22 inch.
Some improvement has been made with the advent of indicating
targets. These have included one comprising a stretched rubber
membrane which, when punctured, revealed a contrastingly colored
backing sheet. Another type used a resiliently deformable material
mounted behind an inelastic paper target sheet. A third type relied
upon the action of fluid released by projectile puncture of a
capsule. Other types used further relatively complex schemes. While
providing improved visibility vis-a-vis the simple paper target,
these prior art indicating targets suffered from the drawbacks of
high cost due to expensive materials or complex assembly
requirements, or they were difficult to mass produce, again
resulting in high cost. Also, their reliability and point of impact
visibility was less then desirable. As a result, no relatively
inexpensive, reliable, high visibility indicating targets are yet
available, to the best of my knowledge.
The present invention overcomes the drawbacks of the prior art
indicating targets by employing a construction which can be
duplicated substantially entirely by processes currently in use in
the printing industry. It is therefore extremely inexpensive to
produce, yet produces a very high contrast indication of the point
of bullet impact in a reliable manner.
Accordingly, several objects of the present invention are to
provide an indicating target which overcomes the drawbacks of prior
art indicating targets, which is inexpensive to produce, which is
amenable to mass production techniques, which is reliable in
operation, and which provides a high contrast indication of the
point of bullet impact. Additional objects and advantages will
become apparent from the ensuing description thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The indicating target according to the invention (FIG. 1) comprises
a transparent (plastic) frame 10, a metal foil sheet 12, preferably
of aluminum, having a conventional target pattern printed thereon,
and a contrasting backup sheet 14, preferably comprising a
brightly-colored paper sheet having a target pattern printed on the
front surface thereof which is congruent with the target pattern
printed on foil sheet 12. Foil sheet 12 is thus mounted in a flat
upright position; the part of sheet 12 having the target pattern
thereon, i.e., the part of sheet 12 other than the edges thereof,
is spaced from or free of all other parts of the target assembly so
that substantially any portion of sheet 12 may be torn and freely
displaced from the rest of sheet 12 by a projectile's (bullet's)
impact, as explained infra. Preferably the front surface of backup
sheet 14 is dyed or printed bright red or orange in fluorescent
colors to provide maximum contrast with foil sheet 12. Means to
suspend the target frame are provided by mounting tab 16 which is
suitably affixed to frame 10.
Frame 10 is preferably formed of a transparent plastic such as
methyl methacrylate (sold under the marks Lucite and Plexiglass) in
order to allow ambient light to illuminate backup sheet 14. However
wire or celluloid box frames are also suitable, especially where
cost is an important factor. Foil sheet 12 and backup sheet are
preferably affixed to the front and rear sides, respectively, of
frame 10 by adhesive, but stapling, tacking, taping or other
suitable means may be used. The preferred dimensions of target
sheet 12 and backup sheet 14 preferably conform to the National
Rifle Association standard target sizes for the various range
distances and calibers and the spacing between sheets 12 and 14
should be about 1/4 the width of sheets 12 and 14. For example, for
use in a 50 foot small bore rifle range, the target should be 9 by
7 inches and sheets 12 and 14 should be 1.75 inches apart.
While certain specific features of the invention have been shown
and discussed in the above preferred embodiment, various omissions,
substitutions, and changes in the form and details of the device
illustrated and in their operation may be made within the scope of
the invention.
For example, the target pattern may be omitted from the backup
indicator sheet 14.
In another modification the backup sheet 14 may be omitted,
especially if ambient or background light is sufficient to show
through the holes made in the metal foil to provide adequate
viewing contrast.
In another modification frame 10 may be opaque (e.g., wood or
cardboard), and backup sheet 14 translucent (but still of a bright
high contrast color) such that light from the surroundings behind
the target will pass therethrough and thus illuminate the
brightly-colored surface thereof.
While the complete target assembly is preferably sold as a
disposable unit, frame 10 can alternatively comprise a
semi-permanent unit which can be used with replaceable sheets 12
and 14 until it (frame 10) no longer is serviceable (due to bullet
impact damage).
OPERATION OF THE PREFERRED EMBODIMENT
The invention takes advantage of the fact that certain metal foils
(e.g., 0.025 mm thick aluminum) have been found to form a
substantially larger-than-projectile-size hole when struck by a
rapidly moving (about 300 meters per second) projectile. Cf.
commonly used paper targets which form a hole which is actually
smaller than the projectile size. In the metal foil sheet 12 of the
invention a hole 20 (FIG. 2) formed by a bullet typically assumes a
hexagonal shape shown, with the foil from the hole tearing and
folding around to the rear side of the foil sheet 12 as indicated
in FIG. 3. The projectile also produces a
smaller-than-projectile-size hole 22 in backup sheet 14. Since
frame 10 is transparent, ambient light passes through the exposed
frame, illuminating the brightly-colored backup sheet 14.
The net result is that a larger-than-projectile caliber, high
contrast, point of impact indication is produced. This indication
has been found to be highly visible at normal target range
distances. Since backup sheet 14 also contains target lines, the
precise point of projectile impact 22 can still be determined for
scoring purposes.
While the above description contains many specificities, these
should not be construed as limitations upon the scope of the
invention but merely as an exemplification of several preferred
embodiments thereof. The true scope of the invention is indicated
by the subject matter of the appended claims and their legal
equivalents.
