| Abstract: |
A batting practice device is disclosed which is a tubular elastomeric cylinder closed at both ends and having a mounting tube down the center with a bore capable of receiving a rope or other tension suspension member. A valve is provided for filling the interior portion of the closed end cylinder to a depth of 30% to 70% of the volume with a fluid such as water. The method contemplates providing a batter with such a structure, and repetitively swinging a bat against the subject device to simulate the resistance rebound effect of striking a ball.

First Claim:
Show all 4 claims |
What is claimed is:
1. A batting practice device comprising, in combination,
- an elastomeric tubular cylinder closed at both ends,
- a mounting tube concentric with said cylinder and sealed in fluid tight relationship at its lower end to define a rope bore therein of a non-interrupted nature from end to end of the cylinder,
- a filling means at the upper end of said cylinder for the injection of fluid and retention of said fluid,
- a single flexible tension member inserted in the rope bore and extending upwardly to a support, and terminating at a securing element at the lower end,
- said cylinder containing non-gaseous fluid to a level between 30%-70% of the volume capacity of the closed end cylinder for providing sufficient inertia to present to a bat striking against said cylinder the resistive forces of simulating striking a ball,
- said tension member proportioned so that the cylinder is horizontally opposed to a major portion of the strike zone of a batter,
- said support and tension member aligned so that the cylinder is vertically opposed to a major portion of the strike zone of a batter relative to an imaginary home plate,
- whereby the device substantially occupies airspace defining a strike-zone.
