Abstract

Abstract A batting practice device for aiding a batsman to perfect a level swing includes a pair of elongated, vertically spaced, inclined tubular arms resiliently mounted at their inner ends on a mounting plate. The arms provide an unobstructed substantially horizontal target area for passage of a bat therebetween during a practice swing. An adjustment assembly is also provided for raising and lowering the mounting plate to vary the height of the arms relative to the strike zone.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 94 words
A batting practice device, comprising: a mounting plate; a pair of elongated arms resiliently mounted at their inner ends on said plate and projecting outwardly therefrom, said resilient mounting includes spring means between the inner end of each of said elongated arms and said mounting plate, said elongated arms being spaced apart and parallel to one another and disposed at an upward inclination from said mounting plate to form an unobstructed target area for passage of a bat therebetween during a practice swing; and means for releasably securing said plate to a supporting structure.
Claim 2
Dependent Claim 94 words
A batting practice device, comprising: a mounting plate; a pair of elongated arms resiliently mounted at their inner ends on said plate and projecting outwardly therefrom, said resilient mounting includes spring means between the inner end of each of said elongated arms and said mounting plate, said elongated arms being spaced apart and parallel to one another and disposed at an upward inclination from said mounting plate to form an unobstructed target area for passage of a bat therebetween during a practice swing; and means for releasably securing said plate to a supporting structure.
Claim 3
Dependent Claim 52 words
The batting practice device of claim 1, wherein said spring means if a coil spring affixed at one end to said mounting plate and having an inner diameter substantially identical to the outer diameter of said elongated arm for receiving the inner end of said elongated arm in a press fit arrangement.
Claim 4
Dependent Claim 37 words
The batting practice device of claim 1, wherein said elongated arms are tubular in shape and are comprised of a resilient plastic material so as not to be permanently deformed upon being accidentally struck by a bat.
Claim 5
Dependent Claim 32 words
The batting device of claim 1, further including indicia means on said elongated arms to provide assistance to a batter in aligning the hitting portion of a bat within the target area.
Claim 6
Dependent Claim 153 words
A batting practice device, comprising: a mounting plate; a pair of elongated arms resiliently mounted at their inner ends on said plate and projecting outwardly therefrom, said elongated arms being spaced apart and parallel to one another and disposed at an upward inclination from said mounting plate to form an unobstructed target area for passage of a bat therebetween during a practice swing; and mean for releasably securing said plate to a supporting structure, said securing means includes an adjustment means for raising and lowering said mounting plate on said securing means, and said adjustment means includes a bracket member having a channel formed therein running along its length, said channel having a longitudinal axis substantially perpendicular to the ground, a key member associated with said mounting plate and slidably received within said channel, and means cooperating with said key member for locking said plate in the desired position on said bracket member.
Claim 7
Dependent Claim 153 words
A batting practice device, comprising: a mounting plate; a pair of elongated arms resiliently mounted at their inner ends on said plate and projecting outwardly therefrom, said elongated arms being spaced apart and parallel to one another and disposed at an upward inclination from said mounting plate to form an unobstructed target area for passage of a bat therebetween during a practice swing; and mean for releasably securing said plate to a supporting structure, said securing means includes an adjustment means for raising and lowering said mounting plate on said securing means, and said adjustment means includes a bracket member having a channel formed therein running along its length, said channel having a longitudinal axis substantially perpendicular to the ground, a key member associated with said mounting plate and slidably received within said channel, and means cooperating with said key member for locking said plate in the desired position on said bracket member.
Claim 8
Dependent Claim 39 words
The batting practice device of claim 5, wherein said bracket member includes a pair of opposite inwardly directed flanges forming a T-shaped channel, said flanges overlapping the edges of said key member to provide a sliding bearing surface therefor.
Claim 9
Dependent Claim 59 words
The batting practice device of claim 6, wherein said key member includes a threaded shank portion projecting from said channel, said mounting plate includes a hole for receiving said shank portion, and said locking means includes a wing nut threadedly engaged on said shank portion so that when turned down thereon said plate is secured to said bracket member.
