ABSTRACT:
The soccer training apparatus consists of a rebounding wall which is about four by eight feet. The wall in turn is yieldably mounted on a rectangular support frame, which frame may be mounted on a usual field sled or any suitable base. Two support rollers are mounted below the wall to track along the support sled, or shelf, if preferred. Tension control of the rebounding surface is accomplished by six control bolts which are ball and socket mounted on the reverse or back side of the rebounding wall and pass through enlarged apertures in the support frame. Suitable compressible springs are mounted about the control bolts and positioned between the rebounding wall and the support frame. The final control of the rebounding surface is accomplished by manually adjustable nuts threaded on the protruding ends of the control bolts. The ends of the control bolts are attached to the back of the rebounding wall in sockets secured thereto, which permit a few degrees of canting or tilting that can occur when the ball strikes the surface at various angles and positions.
In addition, two or more practice walls can be joined together, in flexible relation to each other, by passing a pair of bolts through two adjacent spaced apart frames with a yieldable spacer sleeve about each of the bolts.
