Description




BACKGROUND OF THE INVENTION




This invention relates to a slingshot and, more particularly, to a slingshot body for use with an elastic member in slinging a projectile.




Slingshots have been used for many years. Normally, a user of the slingshot wraps a pouch around a projectile, overcomes the resistance caused by elastic members connected to the arms of a forked portion of the body and moves the pouch into a projectile launching position. Unless the user holds the forked portion exactly perpendicular to a projectile release point, the elastic members may apply unequal forces to the pouch. In which event, the projectile will not fly as true a course as the user desires. Further, after the projectile is released, the user may change his or her grip on the slingshot body that will effect the positioning of the forked portion relative to the release point and result in a lack of repeatability in using the slingshot. In order to eliminate these problems, an improved slingshot body is provided for use by a slingshot user.




Accordingly, it is an object of the present invention to provide a slingshot body for use with an elastic member in slinging a projectile. Since the slingshot body has a fork portion pivotally connected to a gripping portion, the fork portion is disposed perpendicular to a user's arm and equal force is applied to the pouch supporting the projectile and thereby improve the flight of the projectile toward the target.




BRIEF SUMMARY OF THE INVENTION




In accordance with the present invention, there is provided a slingshot body for use with an elastic member in slinging a projectile. A fork portion to which the elastic member is to be attached and a gripping portion to be grasped by a user of the slingshot body are provided. Mounting apparatus pivotally connects the fork portion and the gripping portion to one another to allow movement of the gripping portion within the user's hand without effecting the force applied on each side of the pouch by the elastic members.




Further, in accordance with the present invention, there is provided a slingshot body for use with an elastic member in slinging a projectile. A fork portion to which the elastic member is to be attached and a gripping portion to be grasped by a user of the slingshot body are provided. Pivotal connecting apparatus is then used to pivotally connect the elastic member to said fork portion.




Further, in accordance with the present invention, there is provided a slingshot body for use with an elastic member in slinging a projectile. A fork portion to which the elastic member is to be attached and a gripping portion to be grasped by a user of the slingshot body are provided. A stabilizing member is used to inhibit undesired movement of said fork portion.

As shown in

FIGS. 4 and 5

, when slingshot


10


is used, a user inserts his or her hand through wrist support


38


and grasps gripping portion


20


in a conventional manner. A projectile is then positioned in pouch


18


in a conventional manner and pouch


18


moved to a launching position, as indicated in solid outline. Should gripping portion


20


or pouch


18


be at a different launching position or point, as indicated in dotted outline, than previous launching positions, fork portion


44


of slingshot


10


rotates to align pouch


18


to be equidistant from arms


48


and


50


. By this rotation into alignment, the launch point of pouch


18


is equidistant from arms


48


and


50


and the force provided by elastic members


14


and


16


should be equal. Thus, each projectile thrown from slingshot


10


should pass through the point where elongate axis


37


crosses pivotal axis


59


to, thereby, provide enhanced performance for the user through better repeatability of shots.




Moreover, the projectile should pass through the point where elongate axis


37


crosses pivotal axis


59


when slingshot


10


is held by the user in a generally vertical or upright position with a sight being used mounted on third mounting bracket


84


or when slingshot


10


is rotated 90° in a generally horizontal position with a sight being used mounted on first or second mounting brackets


60


and


68


, respectively.




Further, by constructing slingshot body


10


with elongate axis


37


and pivotal axis


59


and these axes are in the same plane, arms


48


and


50


of fork portion


44


will be perpendicular to the launch point of pouch


18


when a user of slingshot


10


moves pouch


18


into a launch position, as shown in

FIGS. 4 and 5

.
