Abstract
ABSTRACT OF THE DISCLOSURE
The present invention provides an arrow-like projectile which is launched through an overhand throwing action. The projectile includes a weighted head, an elongated shaft, a rear empennage and a launcher receiving member towards the rear of the shaft. The launcher receiving member is arranged to receive a hand launcher in a manner such that the launcher pulls the projectile forwardly and draws the rear empennage downwardly during the overhand throwing action of the projectile.

Description
1 ~7 ____________________.__ The present invention relates to a hand launched projectile having an arrow-like configuration. The projectile which is launched through an overhand throwing action may be used as a toy or as a form of sport where the projectile is thrown at a target for determining marksmanship.
BACKGROUND OF T~E INVENTION
________________ There are presently available a number of different types of arrangements which are used for launching an arrow or an arrow-like member. The most common arrangement is the standard bow and arrow. A cross-bow which is more rare than the bow and arrow is another example of this type of arrangement.
Both of the examples given above rely upon the use of a launching mechanism which must be quite substantial in order to produce effective results. Accordingly the cost of even a fairly reasonable bow is generally more than that which can be afforded by most children as a toy item. The same is true of a cross-how which is more expensive still than a standard bow. Furthermore~ both the bow and the cross-bow are subject to damage incurring further expenses when parts have to be replaced. In addition, both of these items are extremely dangerous in the hands of a child.
SUMMARY OF _~E_PRESENT_IN_EN_ION
The present invention provides an arrow-like projectile adapted for use with a launcher for launching the projectile through an overhand throwing action rather than a mechanical laullching action. The projectile ï~76~
1 comprises a weishted head, an elongated shaft, a rear empennage and launcher receiving means towards the rear of the shaft. The launcher receiving means is arranged to receive a loop forming portion on the launcher such that the projectile is pulled forwardly and the rear empennage drawn downwardly during the throwing action and such that the launcher receiving means automatically releases the loop forming portion of the launcher after completing the throwing action.
The launcher itself need not be complicated whatsoever and may typically be in the form of a simple piece of rope or the like which unexpectedly produces extremely long flights of the projectile. However, unlike the prior art arrangements the cost of the system is kept extremely low with the launcher itself being readily replaceable. Furthermore since the launching is accomplished through a throwing action the projectile is not subject to premature launchings and therefore much safer than a bow and arrow.

DETAILED DESCRIPTION ACCORDING TO TEIE PREFERRED EMBODIMENTS
____________________ ____________ ____________ __________ As shown in Figure 1, a preferred embodiment of a hand launched projectile comprises an elongated shaft 3 provided near its forward tip 7 with a weighted portion 5 and near its rear end with a empennage or tail section 9. Located slightly in front of the rear empennage is a groove 11 directly in the shaft 3 of the projectile.
This groove is adapted to receive a piece of string or cord 13 which is looped upon itself at 15 without being tied into a knot as shown in Figure 2.
In order to prepare the projectile for launching a string 13 is wound once in the groove 11 and extended taughtly towards the front of the projectile thereby drawing the loop tightly into the groove. When the projectile is actually launched the string is held as shown in Figure 3 in the hand that is used to throw the projectile which is positioned on the shaft slightly behind the weighted portion 5. As the projectile is launched through an overhand throwing action the hand is released from the shaft while the string 13 remains tight while it pulls forwardly on the shaft in the groove and ~7~
1 draws the rear section of the projectile downwardly.
This in turn raises the forward tip while the projectile is whipped along its flight path by the string. Since the string is not actually tied into a knot it automatically releases from groove 11 with the completion of the overhand throwing action.
Figure 4 shows the flight path FPl of the projectile when it is simply launched without the use of string 13.
It will be seen that this particular flight path begins to decend as soon as the throwing action is completed.
However, as shown in Figure 5, when the projectile is launched by means of string 13 looped into the groove to the rear of the projectile a flight path FP2 is established. This flight path through the downward drawing action of the tail, begins to climb immediately upon launching and only falls off as gravity overcomes the accelleration of the projectile.
The distances over which the projectile as shown in Figure 3 can be ]aunched, are amazing. Furthermore after a number of uses the accuracy with which the projectile can be launched is easily controlled. Accordingly the projectile can be used with a target or the like in accuracy competitions. It may also be used simply as a toy thrown between children in which case the forward tip 7 of the projectile would be provided with some type of a blunt and preferrably softened surface.
Figure 6 shows a somewhat modified projectile 21 from that shown in Figure 1. Projectile 21 comprises an elongated shaft 23 having a weight 25 near its forward end 27 and a rear empennage 29. Located slightly 1 forwardly of the rear empennage is a rearwardly projecting barb 31 which is adpated to receive a loop 35 of a piece of string or cord 33. Unlike the earlier arrangement loop 35 may be tied as indicated at 36 to maintain the shape of the loop.
The launching of projectile 21 is essentially the same as the launching described above with respect to projectile 3 except that the permanent loop 35 is fitted over barb 31 rather than around the shaft. The cord which is inelastic in nature for controlling the accuracy of the throw pulls the projectile forward at the barb 31. The loop which stays on the barb until the throwing action is completed pivots or flexes relative to the taut portion of the cord in order to provide the downward drawing of the rear empennage while the projectile is being pulled fowardly. The rearward sloping of the barb ensures that the loop 35 even through it is knotted at 36 automatically releases from the projectile without affecting its accelleration during the launching.
It should be noted that unlike a standard arrow the projectile of the present invention is not launched from the extreme rear end of the projectile. According to the present invention the launcher receivig means, although located towards the rear of the shaft, is away from the end of the projectile~ The launcher receiving means is preferrably positioned such that the projectile is tipped to about a 45 degree angle when thrown to provide maximum flight. If the launcher receiving means were located at the end of the projectile it would simply flop straight upwardly at launching rather than taking off on an 1~76~
1 extended flight pattern.
As wi]~ be seen from the description above, both the projectile and the entire system of the present invention is extremely simple in nature and do not require complicated operating parts. Furthermore, it is safe to use with little or no change of an accidental launching as is the case with prior art structures.
It is to be appreciated that other launching means such as a bar or stick with a pivotal loop at one end could equally as well be used with either of the arrangements shown in Figures 1 and 6 for launching of the projectile. Therefore, although various preferred embodiments of the invention have been described herein in detail it will be appreciated by those skilled in the art that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.
