  • Patent number: 5803067
    Abstract: 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.
