Foldable basketball shooting device

Abstract

The present invention relates to a foldable basketball shooting device which comprises a backboard, a hoop, foldable frame structures, a pair of side fabric guards and a fabric bottom. The backboard is composed of four pivotally connected rectangular boards, two upright frame bars in the back and a hoop engaged in the front thereof. The foldable frame structures include side frame bars, upper supporting legs, first, second and lower supporting legs accompanied with collapsible joints and crossed connecting joint members wherein said side frame bars, upper supporting legs, first, second and third pair of lower supporting legs are respectively in different length. The side fabric guards are respectively extending upwardly from the side frame bars and inclining correspondingly toward two side edges of the backboard for preventing basketballs from dropping off. Catching returned basketballs is provided with said fabric bottom mounted to the side frame bars.

1 . A foldable basketball shooting device, comprising: a backboard, a hoop, foldable frame structures, a fabric bottom and a pair of side fabric guard, wherein said backboard is composed of four rectangular foldable boards having two upright frame bars installed at the back and said hoop mounted to the front thereof; said foldable frame structures includes two pairs of side frame bars, three pairs of upper supporting legs, first pair of lower supporting legs, second pair of lower supporting legs and third pair of lower supporting legs accompanied first pair of collapsible joints, second pair of collapsible joint, third pair of collapsible joints and three crossed connecting joint members wherein said side frame bars, upper supporting legs, first, second and third pair of lower supporting legs are in different length; said pair of side fabric guards are extending upwardly and inclining from the distal to proximal end of said pairs of side frame bars correspondingly to two side edges of said backboard for preventing basketballs from dropping off; and said fabric bottom is mounted between said pairs of side frame bars for catching returned basketballs. 
   
   
       2 . A foldable basketball shooting device, as recited in  claim 1 , wherein said two pairs of side frame bars are pivotally connected with each other by said second pair of collapsible joints, said first, second and third pair of upper supporting legs are pivotally mounted to said frame bars respectively against said first, second and third pair of collapsible joints, said first pair of lower supporting legs is shorter than said second pair of supporting legs which are shorter than said third pair of supporting legs in sequent; first pair of intra-leg foldable joints are pivotally installed on the relative middle position of said second pair of lower supporting legs respectively; second pair of intra-leg foldable joints are pivotally installed on the relative middle position of said third pair of lower supporting legs respectively; and three crossed connecting joint members are relatively engaged between said first, second and third pair of lower supporting legs. 
   
   
       3 . A foldable basketball shooting device, as recited in  claim 1 , wherein said crossed connecting joint is composed of two connecting plates which respectively have pin holes correspondingly located at the crossed section thereof and pivotally engaged with each other. 
   
   
       4 . A foldable basketball shooting device, as recited in  claim 1 , wherein said third pair of collapsible joints permits the head portion thereof pivotally folded laterally.
