Abstract
An apparatus for teaching a person a technique for striking a volleyball. The apparatus has a chute with first and second side walls for directing volleyball toward a pivotable arm attached to the chute. A passage in the arm connects a cone thereon with a source of vacuum while the weight of a valve on the arm positions the arm in a vertical position. An indexing member sequentially retains volleyballs in the chute and sequentially presents a volleyball to the cone. An input acts to release a lock on the indexing member and thereafter allow a volleyball to roll from the chute toward the cone where the vacuum sucks the volleyball onto the cone. The weight of the volleyball causes the arm to pivot from the vertical position and rotate the volleyball to a position for a player to spike the volleyball.
Claims14
An apparatus for allowing a person to practice spiking a volleyball comprising:
- a support;
- a chute having parallel first and second side walls that are connected to a base that is attached to said support, said first side wall having a first end and second end with a first inwardly projecting member extending from said first end, said second side wall having a third end and a fourth end with a second inwardly projecting member extending from said third end;
- an arm having a body with a passage that extends from a first end and a second end including a collar that surrounds said first and second inwardly projecting members to connect said passage with a corresponding passage in at least one of said first and second side walls, said collar in surrounding said first and second inwardly projection members allowing said body to pivot about said first and second inwardly projection members;
- a cone secured to the first end of said body;
- a valve attached to the second end of said body, said valve having sufficient weight such that at rest said arm is located in a substantially vertical position with respect to said base;
- a source of vacuum connected to said body for drawing air through said passage from the surrounding environment by way of said cone and valve;
- indexing means for retaining a volleyball in said chute;
- and
- actuation means for allowing a volleyball to move from said indexing means toward the first end of said chute and onto said cone such that said vacuum pulls on and holds said volleyball on said cone, said cone with a volleyball attached thereto having a greater weight than said valve and as a result said arm pivots on said first and second inwardly projections and said volleyball is moved from the position of rest for said arm to a position where a player may spike the volleyball.
