ABSTRACT:
A slingshot device for accurate shooting of a projectile having an elongated stationary support channel having forward and rearward portions. A movable carriage is slidably engaged by the stationary support channel and movable between an extended, forward cocked position and a retracted rearward holding position. A locking device is mounted on the forward portion of the elongated stationary support channel to releasably lock the carriage in the extended, forward cocked position. An elongated elastic band has opposite ends mounted in vertically spaced relation on the carriage. A pouch for releasably retaining the projectile is positioned at a midpoint of the elastic band device. A trigger is mounted on the stationary support channel and movable between an engagement position in releasable engagement with the pouch of the elastic band device, and a release position. Upon movement of the carriage to the forward cocked position, the elastic band is substantially stretched such that when the trigger is released, the elastic band is operative to propel a projectile in the pouch forwardly.
The slingshot apparatus may also include a sighting device mounted above the departure path of line of departure of the projectile. The sighting device may have a plurality of sighting apertures to accommodate different target distances.
