Volleyball spiking training device
A volleyball spike training system comprises a ball holder and an optional net. The training holder comprises a wheeled chassis supporting a vertical stanchion projecting upwardly that supports a hopper and a ball feeding apparatus. The stanchion includes a crank system for vertically adjusting telescoped stanchion segments. Balls dropping from the hopper travel by gravity down an inclined ramp at the top of the frame towards a discharge throat. Balls travelling down the ramp are indexed by a Z-shaped lever that serially separates them. A pair of downwardly projecting hands, one fixed and one pivoted, receive dropping balls and temporarily hold them for shooting. The pivoting hand controls the indexing lever to jam successive balls when the device is loaded. When a ball is shot and removed from between the feed hands, another ball is freed by the indexing lever to automatically drop into a shooting position between the hands.
1. A training device for teaching the spiking of balls, the device comprising:
a chassis adapted to be disposed upon a playing surface;
a support stanchion extending vertically upwardly from said chassis;
a hopper for receiving balls, the hopper supported by said stanchion and comprising a ball output passageway;
a ball discharge throat spaced apart from said hopper;
an inclined feeding ramp for receiving balls from said hopper and guiding them towards said discharge throat;
a pair of hands for temporarily holding balls dropping through said discharge throat until the ball is stricken; and,
an automatic indexing system for establishing one-at-a-time ball travel through said discharge throat in response to movement of at least one of said hands.
2. The training device of claim 1 wherein at least one hand is pivotally displaceable.
3. The training device of claim 2 wherein the indexing system is moved by said displaceable hand when a ball is loaded for spiking.
4. The training device of claim 2 wherein said indexing system moves to a ball restraining position preventing balls from passing through said throat when a ball to be spiked is positioned between said hands.
5. The training device of claim 4 wherein said indexing system comprises a weight for automatically moving the indexing system to allow a subsequent ball to drop through said throat after a spike, and wherein movement of said indexing system moves said displaceable hand.
6. The training device of claim 4 wherein said indexing system comprises at least one pivoted Z-shaped lever mechanically coupled to said displaceable hand.
7. The training device of claim 6 wherein each Z-shaped indexing lever comprises a bottom segment to which said displaceable hand is mounted, an integral intermediate segment, and an integral, upper segment projecting towards said throat from said intermediate segment for contacting balls.
8. The training device of claim 5 wherein said indexing system is secured to a hinge proximate said throat.
9. The training device of claim 1 wherein said stanchion comprises a telescoping section, and the device comprises a rotatable crank for adjusting the length of said stanchion.
10. A volleyball training device for teaching the spiking of balls, the device comprising:
a chassis adapted to be disposed upon a playing surface;
an adjustable support stanchion extending vertically upwardly from said chassis;
a hopper for receiving balls, the hopper supported by said stanchion and comprising a ball output passageway;
an inclined feeding ramp for receiving balls from said hopper output passageway; a ball discharge throat spaced apart from said hopper towards which balls on said ramp move;
a pair of hands for temporarily holding balls dropping through said discharge throat until the ball is stricken, wherein at least one hand is pivotally displaceable; and,
an automatic indexing system for establishing one-at-a-time ball travel through said discharge throat in response to movement of at least one of said hands.
11. The training device of claim 10 wherein the indexing system is moved by said displaceable hand when a ball is loaded for spiking towards a position to block a subsequent ball from dropping through said discharge throat.
12. The training device of claim 11 wherein said indexing system comprises a weight for automatically moving the indexing system out of the way to allow a subsequent ball on said ramp to drop through said throat after a spike, and wherein said movement of said indexing system moves said displaceable hand.
13. The training device of claim 12 wherein said indexing system comprises at least one pivoted Z-shaped lever mechanically coupled to said displaceable hand.
14. The training device of claim 12 wherein the indexing system comprises at least one indexing lever comprising a bottom segment to which said displaceable hand is mounted, an integral intermediate segment, and an integral, upper segment projecting towards said throat from said intermediate segment for contacting balls.
15. The training device of claim 14 wherein said indexing system is secured to a hinge proximate said throat.
16. A volleyball training device for teaching the spiking of balls, the device comprising:
a chassis adapted to be disposed upon a playing surface;
an adjustable support stanchion extending vertically upwardly from said chassis;
a hopper for receiving balls, the hopper supported by said stanchion and comprising a ball output passageway;
an inclined feeding ramp for receiving balls from said hopper output passageway; a ball discharge throat spaced apart from said hopper towards which balls on said ramp move;
a pair of hands for temporarily holding balls dropping through said discharge throat until the ball is stricken, wherein at least one hand is pivotally displaceable; and,
an automatic indexing system for establishing one-at-a-time ball travel through said discharge throat in response to movement of at least one of said hands, the indexing system comprising at least one indexing lever comprising a bottom segment to which said displaceable hand is mounted, an integral intermediate segment, and an integral, upper segment projecting towards said throat from said intermediate segment for contacting balls.
17. The training device of claim 16 wherein the indexing system is moved by said displaceable hand when a ball is loaded for spiking towards a position to block a subsequent ball from dropping through said discharge throat, and wherein said indexing system comprises a weight for automatically moving the indexing system out of the way to allow a subsequent ball on said ramp to drop through said throat after a spike, and wherein said last mentioned movement of said indexing system moves said displaceable hand.
18. The training device of claim 17 wherein said indexing system is secured to a hinge proximate said throat.
19. The training device of claim 16 wherein said indexing system comprises at least one pivoted Z-shaped lever mechanically coupled to said displaceable hand.
20. The training device of claim 16 wherein said stanchion comprises a telescoping section, and the device comprises a rotatable crank for adjusting the length of said stanchion by moving said telescoping section.
