An enhanced sight marker apparatus for slingshots, bows, and other projectile launching devices includes a support block with a trough for mounting and retaining an elongated, fluorescent optical fiber. The trough is deep enough to receive a substantial portion of the fluorescent optical fiber for support while leaving some portion of the peripheral surface of the optical fiber unshielded by the support block for exposure to ambient electromagnetic radiation, and the support block also leaves at least one end of the fluorescent optical fiber exposed and visible so that light transmitted in the core of the optical can be propagated from the exposed end to a user's eye.

Enhanced sight marker apparatus

A sling shot includes a basic Y-shaped frame including a handle, two upstanding yoke branches, and two elastic sling straps extending between a respective yoke branch and a pouch for receiving a projectile to be propelled. The upper end of each yoke branch is provided with a connector member rotatably connected thereto, the rotation of each connector member preferably limited to about 180 degrees. Each connector member includes an elongated prong to receive an elastic strap. When the elastic straps are stretched rearward, the connector members will rotate so that the elongated prongs are in line with their respective elastic straps. When the elastic straps are released to propel a projectile, the forward movement will cause the connector members to pivot so that the elongated prongs will remain in line with the ends of their respective elastic straps, thus preventing the elastic straps from going into twists or kinks. Each connector member may also include a strut with a sight bead which is visible in the sight window when the straps are pulled rearward, to assist in aiming.

Pivotal sling strap connectors and sights for slingshots

A folding, wrist braced slingshot having a yolk, a hand grip that stores and dispenses ammunition for use and elastic members connected to said yolk. A wrist brace is frictionally, detachably and pivotably mounted to the hand grip near the base thereof. A pivotable closure means is provided the bottom of the hand grip. The closure swivels to dispense ammunition stored within the hand grip. The yolk comprises a forked portion and a doubled over stem portion wherein the inside base of the stem portion contains a slot and the hand grip contains an inwardly projecting member positioned within said stem portion so that the end thereof fits in said slot.
