ABSTRACT:
A folding slingshot having a yolk, a hand grip and elastic members connected to said yolk. A wrist brace is frictionally, detachably and pivotably mounted to the hand grip near the base thereof. Said wrist brace comprises a pair of longitudinal members diverging rearwardly from the hand grip and spaced apart to receive the wrist between them and an end member integral with said longitudinal members engageable with the user's wrist. A groove is on each side of said handle near the base thereof for receipt of end portions of said longitudinal members. A protruding stop member on said hand grip overhanges each of said grooves and prevents further rotation of said wrist brace. A cam area on said hand grip below each of said grooves containing two spaced apart cam surfaces; said end portions of the longitudinal members encountering said cam surface upon rotation toward said grooves, thereby spreading slightly said longitudinal members so that after passing over said cam surfaces said end portions of the longitudinal members snap into said grooves and rest against said respective stop members to lock said wrist brace in shooting position.
