Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the field of sport-shooting targets. In particular, the present invention is concerned with a frangible, biodegradable and non-toxic shooting target having a body and an internal cavity containing a flowable colorant that expands and spreads upon breakage of the body by a projectile.

2. Description of the Prior Art

Conventional target practice with firearms involves the use of stationary paper targets or skeet, also known as clay pigeons. Because paper targets are generally uninteresting, many sport-shooters substitute other objects such as beverage cans, bottles or other breakable targets. The destruction of these objects when used for target practice is not only dangerous to the shooter because of the risk of flying debris, but the debris is also detrimental to the environment as well as the wildlife that inhabits the particular area.

Skeet is typically mechanically thrown into the air to allow shooters to aim at the skeet and to provide a more realistic practice environment for hunting birds and the like. Once hit, the skeet will shatter and the remains will scatter throughout the surrounding environment. Skeet is typically formed of asphalt pitch which is a toxic and non-biodegradable material and therefore harmful to the environment. Accordingly, a biodegradable stationary or skeet-like target that will not harm the environment and is relatively easy to manufacture is needed.

There is also a need in the sport of skeet-shooting for a target that provides visual confirmation when hit during both shooting practice and competition and is particularly beneficial to home viewers during televised competitions.

SUMMARY OF THE INVENTION

The present invention solves the prior art problems discussed above and provides a distinct advance in the state of the art. In particular, the advanced target system hereof provides a frangible, biodegradable and non-toxic target that is easily manufactured and provides visual confirmation when hit by a projectile.

A first preferred embodiment of the biodegradable target of the present invention includes a body (typically spherical) defining an internal cavity and containing a quantity of a spreadable display material that expands when the body of the target breaks upon impact with a projectile such as a bullet. The preferred target also includes a mounting portion configured to receive a support member, such as a rod or hanger, for stationary positioning of the target. More particularly, the preferred target body is composed of respective quantities of sugar, water and corn syrup.

A second preferred embodiment of the biodegradable target of the present invention includes a generally disc-shaped target body including a sidewall and a bottom wall. The sidewall and bottom wall cooperatively define an internal cavity containing a quantity of display material that expands upon breakage of the target by a projectile. The preferred target is made from a sugar composition. A method of making the target of the present invention is also provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 4, a first embodiment of [0016] target 10 is disclosed. Target 10 includes a body 12 and a mounting portion 14. Body 12 is generally spherically-shaped and presents a sidewall 16 having an outer surface 18 and inner surface 20. Sidewall 18 defines an internal cavity 22 and has a thickness of 0.25 inches which is sufficient to withstand user handling yet break upon impact by a projectile 24 shot from a rifle or pistol at a range of 10-100 yards. It will be appreciated that the thickness of sidewall 18 may vary according to the user's preferences, the range at which the target is being placed, the type of firearm and the type of projectile used. Outer surface 18 presents an outer diameter of from about 1 to 4 inches and inner surface 20 presents an inner diameter of from about 1.5 to 3.5 inches. Mounting portion 14 is generally cylindrical and radially extends from outer surface 18 of sidewall 16. Mounting portion 14 presents an outer surface 26 and an annular generally flat face 28. Outer surface 26 has a diameter smaller than outer surface 18 preferably from about ⅝ to ¾ inches. Bore 30 radially extends from face 28 through mounting portion 14 toward but not through sidewall 18. Bore 30 is configured to receive a support member 32 for positioning target 10 in a stationary manner. The preferred support member 32 may be rod or the like which may be inserted into the ground for positioning target 10. Another preferred support member 32 may be a string or the like having opposed ends wherein one end is coupled with a resilient body configured to be received within bore 30 and the other end is coupled with a hanging member such as a hook to be placed over a tree branch or the like for hanging target 10 at a desired height. Internal cavity 22 is configured to receive a display material 34 therein. Display material 34 may be a powder, liquid or gel capable of expanding and providing a visual marker when body 12 is broken by projectile 24 as shown in FIG. 3. The preferred display material 34 is a flour or other flowable colorant.
Target [0017] 10 is preferably comprised of 75 to 80% by volume of sugar. Any type of edible sugar may be used to provide the preferred composition of the body. In addition to the sugar, preferred components of the body composition include corn syrup, and water. Preferred corn syrup content ranges are from about 15 to 20% by volume and water, preferably distilled water, comprises from about 5 to 10% by volume.
The [0018] preferred target 10 may be formed by molding the preferred mixture of sugar, water, and corn syrup to form a plurality of body segments and preferably two segments. Display material 34 is added to one of the body segments so that, when body segments are joined, display material 34 is contained within internal cavity 22. The body segments may be joined using an adhesive or the like.
In use, a shooter inserts support member [0019] 23 into bore 30 and positions target 10 in the desired location at a desired height. Upon discharge of a firearm, projectile 24 enters and breaks sidewall 18, as shown in FIG. 2, thereby releasing display material 34 which expands and confirms that target 10 has been successfully hit by projectile 24 as shown in FIG. 3. Cross-hairs or other target-identifying designs may be printed on outer surface 18 of target 10 to aid the user in aiming at target 10 for maximum impact.
Referring now to FIGS. 5 and 6, a second embodiment of the present invention is disclosed. A [0020] skeet 36 is provided having the generally disc shape customary in skeet or clay pigeons. Skeet 36 includes a sidewall 38 and a cap 40. Sidewall 38 has a preferred thickness of 0.1 inches and includes a bottom rim 42 and an integral depending annular rim 44. Bottom rim 42 has a preferred diameter of four inches as is customary for skeet or clay pigeons. It will be appreciated, however, that the thickness of sidewall 38 as well as the diameter of bottom rim 42 may vary according to the user's preferences, the type of mechanical skeet-tosser, the type of firearm being used, and the type of projectile used. Annular rim 44 extends radially upwardly from sidewall 38 and presents an outer diameter of two inches. Annular rim 44 cooperatively engages cap 40 to define an internal cavity 46. Internal cavity 46 is configured to receive a display material 48 therein. Display material 48 may be a powder, liquid or gel capable of expanding and providing a visual marker when skeet 36 is broken by a projectile. The preferred display material 48 is flour or other flowable colorant. The preferred total weight of display material 48 is 3 grams and the preferred weight of skeet 36 is 95 grams.
[0021] Skeet 36 is preferably comprised of sugar. The preferred composition contains from about 90 to 95% tableting dextrose and from about 5 to 10% maltose. The preferred skeet 36 may be formed by compression molding the preferred sugar mixture to form sidewall 38 and cap 40. Display material 48 is added to the inner surface of annular rim 44 so that, when annular rim 44 and cap 40 are joined, display material 48 is contained within internal cavity 46. Annular rim 44 and cap 40 may be joined using an adhesive or the like.
In use, [0022] skeet 36 is thrown into the air as a target for a shooter. Upon discharge of the shooter's firearm, a projectile enters and breaks skeet 36 thereby releasing display material 48 which expands and confirms that skeet 36 has been successfully hit by the projectile.
Having described the invention in detail, those skilled in the art will appreciate that other embodiments may be made of the invention without departing from the spirit of the invention described herein. For instance, many different target shapes may be used. Therefore, it is not intended that the scope of the invention be limited to the specific and preferred embodiments illustrated and described herein. Rather, it is intended that the scope of the invention be determined by the appended claims and their equivalents. [0023]
