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.

KNDX'CATING TARGET EMPLOYING FOIL SHEET 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.

DRAWINGS FIG. 1 is an isometric cutaway view of a target assem bly according to the invention.

FIG. 2 shows a portion of the target illustrating the effect of a bullet impact.

FIG. 3 is a rear view of the front layer of the portion shown in FIG. 2.

DESCRIPTION OF THE PREFERRED EMBODIMENT The indicating target according to the invention (FIG. 1) comprises a transparent (plastic) frame 10, ametal foil sheet 12, preferably of aluminum, having a conventional target pattern printed thereon, and acontrasting 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 onfoil sheet 12.Foil sheet 12 is thus mounted in a flat upright position; the part ofsheet 12 having the target pattern thereon, i.e., the part ofsheet 12 other than the edges thereof, is spaced from or free of all other parts of the target assembly so that substantially any portion ofsheet 12 may be torn and freely displaced from the rest ofsheet 12 by a projectiles (bullets) impact, as explained infra. Preferably the front surface ofbackup sheet 14 is dyed or printed bright red or orange in fluorescent colors to provide maximum contrast withfoil sheet 12. Means to suspend the target frame are provided by mountingtab 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 illuminatebackup 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, re spectively, of frame 10 by adhesive, but stapling, tacking, taping or other suitable means may be used. The preferred dimensions oftarget sheet 12 andbackup sheet 14 preferably conform to the National Rifle Association standard target sizes for the various range distances and calibers and the spacing betweensheets 12 and 14 should be about A the width ofsheets 12 and 14. For example, for use in a 50 foot small bore rifle range, the target should be 9 by 7 inches andsheets 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 thebackup indicator sheet 14.

In another modification thebackup 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), andbackup 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 brightlycolored 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 withreplaceable 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 themetal foil sheet 12 of the invention a hole 2t) (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 thefoil sheet 12 as indicated in FIG. 3. The projectile also produces a smaller-than-projectile-size hole 22 inbackup sheet 14. Since frame 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. Sincebackup sheet 14 also contains target lines, the precise point ofprojectile 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.
