## Abstract

Apparatus to accept, hold and release a basketball in game playing situations requiring a "jump ball". The primary components of the apparatus are: a suspension frame; a telescoping elevator unit carried beneath the frame; a basketball accepting, holding and releasing mechanism carried coaxially within the elevator unit; a hoist mechanism for the elevator unit; and, an electrical system for actuating ball release and the hoist mechanism and for signalling the operative condition of the apparatus.

## Claims

### Claim 1

Apparatus for use above a playing court for the game of basketball, comprising: a suspension frame adapted to be secured to a ceiling or structural support above the court; a telescoping elevator unit suspended beneath said frame and having a plurality of coaxially interfitting segments including an outer segment and an inner segment, said outer segment having an upper end adapted to be secured to said frame; a basketball mechanism carried coaxially of said elevator unit inner segment and having arcuately moving paddles to accept and hold a basketball, said paddles being interconnected by a motion linkage to a linkage actuator for selective movement to drop a held basketball toward the playing court; a hoist mechanism mounted on said frame and having a cable trained down and through said elevator unit, the free end of said cable being connected to said basketball mechanism; and, an electrical system to selectively energize said hoist mechanism to raise or lower said elevator unit by movement of said basketball mechanism, and to selectively energize said linkage actuator of said basketball mechanism.

### Claim 2 (depends on 1)

Apparatus according to claim 1, wherein: said suspension frame has channels for securing to a ceiling or structural support, a bottom plate carried by said channels for suspension mounting said elevator unit, a base extending between said channels for mounting said hoist mechanism, and a junction box mounted on a channel for interconnection of said electrical system with a remote power source.

### Claim 3 (depends on 1)

Apparatus according to claim 1, wherein: said elevator unit segments are cylindrical and said outer and inner segments are interconnected by at least one medial segment.

### Claim 4 (depends on 1)

Apparatus according to claim 1, wherein: said elevator unit segments are cylindrical; and the primary axial component of said basketball mechanism is a cylindrical segment having a cross-plate with an outer diameter slightly less than the body diameter of said elevator unit inner segment, there being two said arcuately moving paddles pivotally mounted by fulcrum brackets secured on the inner face of said cylindrical segment and having an upwardly projecting lever, each said paddle lever being pivotally connected to a common motion linkage block, said linkage block being connected to said motion actuator carried by said cylindrical segment crossplate.
