Abstract

Abstract Improved batting tee apparatus useful in teaching the fundamentals of hitting a baseball properly. The tee includes a base that is supported on a member which simulates, or is ''''home plate.'''' Tubes extend upwardly from the base and are in telescoping relation for height adjustment. A rubber ball support is connected to the uppermost tube and is adapted to support a baseball. The tee apparatus may be shifted at will to various locations relative to home plate to simulate high, low, inside or outside pitches and, as a safety measure, may be easily and quickly removed from the home plate area when a runner on third base attempts to score a run. The upwardly extending tubes comprise first and second tubes wherein the upper end of the first tube is provided with an inner bushing for receiving the lower end of the second tube. The second tube is held in the first tube by a thumb screw which extends through the first tube and bushing and abuts the lower end of the second tube. The upper end of the second tube is provided with a tubular ball support. The ball support is provided with a series of spaced apart grooves to enhance frictional engagement with the second tube when telescopically inserted therein.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 232 words
An improved batting tee comprising: a base member adapted to rest upon a surface and free of attachment thereto, said base member having gently rounded edges about its periphery to minimize injury to a person in the event of upset thereof, and having an upstanding tubular socket thereon, a first upstanding tube having its lower end received in said socket and detachably secured therein, a tubular bushing affixed within said tube adjacent the upper end thereof, said bushing providing an aperture of lesser internal diameter than said tube, a second upstanding tube telescopingly received within said first tube and slidably engaged with said bushing, said second tube having enlarged means at the lower end thereof to prevent upward movement of said second tube past said bushing, thumbscrew means releasably locking said tubes in adjusted telescoped position, and, an upright ball support comprising a solid rod of resilient material having a ball-receiving pocket at its upper end, a tapered lower end for frictional insertion into said second tube, said ball support adjacent said tapered lower end thereof being provided with a plurality of peripheral grooves therein to enhance frictional engagement of the ball support with said second tube when inserted therein, an outwardly extending flange thereon adjacent said lower end and having a diameter greater than that of said second tube for limiting the insertion of said ball support into said second tube.
Claim 2
Dependent Claim 232 words
An improved batting tee comprising: a base member adapted to rest upon a surface and free of attachment thereto, said base member having gently rounded edges about its periphery to minimize injury to a person in the event of upset thereof, and having an upstanding tubular socket thereon, a first upstanding tube having its lower end received in said socket and detachably secured therein, a tubular bushing affixed within said tube adjacent the upper end thereof, said bushing providing an aperture of lesser internal diameter than said tube, a second upstanding tube telescopingly received within said first tube and slidably engaged with said bushing, said second tube having enlarged means at the lower end thereof to prevent upward movement of said second tube past said bushing, thumbscrew means releasably locking said tubes in adjusted telescoped position, and, an upright ball support comprising a solid rod of resilient material having a ball-receiving pocket at its upper end, a tapered lower end for frictional insertion into said second tube, said ball support adjacent said tapered lower end thereof being provided with a plurality of peripheral grooves therein to enhance frictional engagement of the ball support with said second tube when inserted therein, an outwardly extending flange thereon adjacent said lower end and having a diameter greater than that of said second tube for limiting the insertion of said ball support into said second tube.
Claim 3
Dependent Claim 40 words
The improved batting tee of claim 1 wherein said base member is further provided with a plurality of apertures therein to reduce the weight thereof the edges of said apertures being gently rounded so as to eliminate sharp edges therefrom.
