An angularly adjustable rebound apparatus for athletic training. A generally rectangular front frame carries a rebound net and is spring-mounted on a similar back frame. Behind the back frame a rigid support base presents generally triangular opposite sides, each having a horizontal bottom side rail, a front side rail extending up from the front end of the corresponding bottom side rail, and a diagonal side rail extending down from the upper end of the front side rail to the rear end of the bottom side rail. Each bottom side rail has top openings at intervals along its length for receiving a locking pin on a corresponding slider. Each slider carries the socket of a ball-and-socket joint which connects the slider to the rear end of a rigid rod which is pivotally connected at its front end to the lower end of the back frame.

1. A rebound apparatus comprising: a support base having a pair of rigid, laterally spaced, opposite, upwardly extending side members; frame means extending between said side members at the front of said support base and pivotally mounted on the upper ends of said side members; means for selectively adjusting the fore-and-aft position of the lower end of said frame means with respect to said support base; and a rebound member on said frame means; said frame means comprising a rear frame horizontally pivoted at the top to said support base, a front frame positioned in front of said rear frame and carrying said rebound member, and springs engaged between said front and rear frames and permitting rearward displacement of said front frame toward said rear frame in response to an impact on said rebound member; said support base comprising a pair of rigid, laterally spaced, opposite, bottom members extending rearward respectively from the lower ends of said side members, each of said bottom members having a plurality of openings spaced apart along its length rearward; and said means for adjusting said frame means comprising a pair of sliders slidably adjustable respectively along said bottom members and a locking member on each slider selectively insertable into said openings in said bottom member, a pair of rigid members respectively extending forward from said sliders and pivotally coupled to said rear frame at its lower end, and a respective ball-and-socket joint connecting the rear end of each said rigid member to the corresponding slider. 2. A rebound apparatus according to claim 1 wherein: said support base has opposite triangular sides having said side members at the front extending up from the front ends of said bottom members and diagonal members respectively extending from the upper ends of said side members to the rear ends of said bottom members, a front bottom member extending between the front ends of said bottom members, and a rear bottom member extending between the rear ends of said bottom members. 3. A rebound apparatus comprising: a support base having a pair of rigid, laterally spaced, opposite, upwardly extending side members; frame means extending between said side members at the front of said support base and pivotally mounted on the upper ends of said side members; means for selectively adjusting the fore-and-aft position of the lower end of said frame means with respect to said support base; and a rebound member on said frame means; said support base comprising a pair of rigid, laterally spaced, opposite, bottom members extending rearward respectively from the lower ends of said side members, each of said bottom members having a plurality of openings spaced apart along its length rearward; and said means for adjusting said frame means comprising a pair of sliders slidably adjustable respectively along said bottom members and a locking member on each slider selectively insertable into said openings in said bottom member, a pair of rigid members respectively extending forward from said sliders and pivotally coupled to said frame means at its lower end, and a respective ball-and-socket joint connecting the rear end of each said rigid member to the corresponding slider. 4. A rebound apparatus comprising: a support base having a pair of rigid, laterally spaced, opposite, upwardly extending side members; frame means extending between said side members at the front of said support base and pivotally mounted on the upper ends of said side members; means for selectively adjusting the fore-and-aft position of the lower end of said frame means with respect to said support base; and a rebound member on said frame means; said support base having opposite triangular sides having said side members at the front, a pair of rigid, laterally spaced, opposite, bottom members extending rearward respectively from the lower ends of said side members and each having a plurality of openings spaced apart along its length rearward, diagonal members respectively extending from the upper ends of said side members rearward and downward to the rear ends of said bottom members, a front bottom member extending between the front ends of said bottom members, and a rear bottom member extending between the rear ends of said bottom members; and said means for adjusting said frame means comprising a pair of sliders slidably adjustable respectively along said bottom members and a locking member on each slider selectively insertable into said openings in said bottom member, a pair of rigid members respectively extending forward from said sliders and pivotally coupled to said frame means at its lower end, and a respective ball-and-socket joint connecting the rear end of each said rigid member to the corresponding slider. 5. A rebound apparatus comprising: a support base having a pair of laterally spaced, opposite sides each having a horizontal bottom side rail, a front side rail extending up from the front end of the bottom side rail and a diagonal side rail extending between the top of the front side rail and the rear end of the corresponding bottom side rail, each bottom side rail having a plurality of openings spaced apart along its length, said support base also having a bottom front rail extending horizontally between the front ends of said bottom side rails, and a bottom back rail extending horizontally between the rear ends of said bottom side rails; a rear frame having opposite side members spaced apart laterally to fit inside said front side rails of the support base and pivotally connected at their upper ends to the upper ends of said front side rails of the support base; a front frame positioned in front of said rear frame; coil springs engaged under compression between said front and rear frames; guides on said rear frame and tongue and roller units on said front frame riding on said guides for helping to support said front frame; a rebound member carried by said front frame; a pair of sliders slidably adjustable respectively along said bottom side rails; a pair of locking pins respectively mounted on said sliders and selectively insertable into said openings in said bottom side rails to lock said sliders in place thereon; a pair of sockets respectively connected to said sliders and located laterally outward from the respective bottom side rails of the support base; and a pair of rigid rods respectively connected pivotally to the lower ends of said side members of the rear frame and each having a ball seated in the socket on that side of the support base. 6. A rebound apparatus according to claim 5 wherein: said rebound member is a flexible and resilient screen extending across said front frame. 7. A rebound apparatus according to claim 6 and further comprising: means for selectively adjusting the compression of said springs between said front and rear frames. 8. A rebound apparatus comprising: a support base having a pair of rigid, laterally spaced, opposite, upwardly extending side members; frame means extending between said side members at the front of said support base and pivotally mounted on the upper ends of said side members; means for selectively adjusting the fore-and-aft position of the lower end of said frame means with respect to said support base; and a rebound member on said frame means; said support base comprising a pair of rigid, laterally spaced, opposite, bottom members extending rearward respectively from the lower ends of said side members, each of said bottom members having a plurality of recesses spaced apart along its length rearward; and said means for adjusting said frame means comprising a pair of sliders slidably adjustable respectively along said bottom members and a lock member on each slider selectively insertable into said recesses in said bottom member, and a pair of rigid members pivotally coupled respectively to said sliders and extending forward from said sliders and pivotally coupled to said frame means at its lower end.
