The support assembly 83 includes opposed leg support assemblies 91 and tray member 93 mounted between the post assemblies 81. Each leg support assembly 91 includes a support leg 94 secured to adjacent lower ends of the post member 86 by bolts 96. The outer ends of each support leg 94 has a suction cup 97 connected thereto for anchoring purposes. The tray member 93 is connected by bolt members 98 and support braces 99 to the lower post members 86. The tray member 93 is adapted to receive a weight such as a sandbag 101 as shown in FIG. 6 to provide additional reaction weight during usage.

The connector means 69 as shown in FIGS. 12 and 13 includes a support arm 103 secured to the post member 84; a brake assembly 104 mounted above the respective connector discs 76; and a bolt member 106 and a wing nut 108 to anchor in an adjusted position. The brake assembly 104 includes a pair of washer members 110 and a pair of brake members 112, each having a central hole 114 to receive the bolt member 106 therethrough. The washer members 110 are preferably constructed of a brake lining type material to retard movement of the backstop means 66 when in the clamped condition of FIG. 12.

The support arm 103 is of an L-shape having a square hole 116 to receive a square head section 118 of the bolt member 106 to prevent rotation of the bolt member 106 on rotation of the wing nut 108 during adjustment. The support members 84 are provided with opposed, aligned holes 120 to receive the bolt member 106 therethrough.

In the use and operation of the embodiment of the collapsible return apparatus 16 as shown in FIGS. 6 and 7, it is assembled as shown in FIG. 6 with the sandbag 101 placed thereupon. It is seen that the backstop means 66 is connected by the panel support assembly 71 so as to be rotatable from the lower position to the second higher playing position as discussed in the first embodiment.

In the other embodiment being the collapsible return apparatus 18 as shown in FIGS. 8, 9, 10, and 11, the identical backstop means 66 and connector means 69 is utilized but having the pivotal frame assembly 78 being collapsible as shown in FIG. 11.

More particularly, the pivotal frame assembly 78 includes opposed pairs of leg assemblies 122 pivotally connected to the respective ones of the support post members 86; outer ends of the leg assemblies 122 interconnected by tray members 124; and transverse tube members 125 interconnecting opposed post members 86. Each leg assembly 122 includes a leg member 126 pivotally connected by a bolt member 127 to the post member 86; a. suction cup 131 mounted on the end of each leg member 126; and an intermediate portion of each leg member 126 secured by a linkage assembly 133 to the adjacent support post member 86.

Each linkage assembly 133 includes pivotally connected first and

second link members

135 and 136 movable from the usage condition of FIG. 10 to the storage or non-usage condition of FIG. 11.

The use and operation of the collapsible return apparatus 18 is substantially identical to that of the previously described return apparatus 16 except having the pivotal frame assembly 78. The backstop means 66 is pivotal through the connector means 69 to various inclined positions for different usages.

All of the projectile return apparatuses and embodiments of this invention have been described as utilized by basketball or baseball players; however, it is obvious that the same can be used by tennis players, soccer players, etc. to practice fielding, throwing, reflexes, endurance, and the like.

As apparent from the foregoing description of preferred embodiments of the projectile return apparatus, a relatively simple and inexpensive means has been provided which is readily attachable to a given surface so as to provide an economical and effective means of developing and testing a players relative skill. The projectile return apparatus eliminates a great deal of time consuming tedious work involved in practicing various game plays which results in the ability of a single player to practice by himself thereby allowing each to proceed at his own pace required to improve. Additionally, the return apparatus of this invention provides a means for repeatedly practicing a given maneuver by a basketball player whereas it is a proven fact that repeated practice results in a tremendous increase in the players relative skill as the maneuver becomes substantially automatic.
