Abstract
Abstract A backstop return panel is spaced forwardly from a rearwardly inclined, telescopic, support post by two pair of side braces. Each pair of side braces is secured to respective opposite ends of a shaft which in turn is mounted to the support post for pivotal movement about a horizontal axis by a releasable clamp. The support post is mounted to an X-shaped base. Each foot of the base is telescopic and has mounted at its outer end a flanged suction cup with a hole at the midpoint of the flange, and a suction cup release device comprising a pivoted roller.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
241 words
An improved projectile return apparatus comprising; a. a backstop means having a return panel member connected to a panel support assembly, b. a base frame means having attachment means to be releasably connected to a support surface and held against lateral movement, c. said base frame means including a support post assembly and extended in a plane at an angle relative to the support surface, d. means adjustably connecting said backstop means to said base frame means whereby said return panel member may be adjusted horizontally and vertically to return a projectile thrown against said panel member at a desired angle and direction, e. said support post assembly including a main upright post member extended in a rearwardly inclined plane and having a clamp assembly at the upper end thereof engagable with said connecting means, f. said connecting means including first and second telescoping tube members having the upper end of said first tube member secured through a clamp connector assembly to said backstop means and the lower end of said second tube member telescopingly received within said post mEmber and secured in an adjusted position by said clamp assembly, g. said panel support assembly having pairs of cooperating side brace mtmbers, each pair of said side brace members secured to respective opposite ends of a common support shaft, and h. said clamp connector assembly mounted about said support shaft to anchor same in an adjusted position about a horizontal axis.

Claim 3
Dependent Claim
137 words
An improved projectile return aparatus as described in claim 1, wherein; a. said base frame means having a base support assembly secured as by an anchor assembly to said support post assembly, b. said base support assembly including a plurality of telescoping leg assemblies having their inner ends secured to said anchor assembly and the outer ends secured to support cup members operable to contact and grasp the support surface to provide lateral and vertical stability, c. said support cup members having respective holes in outer flanges to initially contact and subsequently release from the support surface for ease of disconnection for movement to a different location, and d. said telescoping leg assemblies having release means connected to outer ends thereof movable to engage the support surface to release respective ones of said support cup members therefrom.
Claim 4
Dependent Claim
152 words
An improved projectile return apparatus comprising; a. a backstop means having a return panel member connected to a panel support assembly, b. a base frame means having attachment means to be releasably connected to a support surface and held against lateral movement, c. said base frame means including a support post assembly and extended in a plane at an angle relative to the support surface, d. means adjustably connecting said backstop means to said base frame means whereby said return panel member may be adjusted horizontally and vertically to return a projectile thrown against said panel member at a desired angle and direction, and e. said base frame means including telescoping leg assemblies with the outer ends having support cup members and having releasable roller assemblies pivotally connected to outer ends of said telescoping leg assemblies movable to engage the support surface to release respective ones of said support cup members therefrom.
