Abstract
Abstract A tennis training device includes a rod secured vertically above the tennis court net and having three successive length sections demarked by different colors to guide a tennis player regarding the height of the ball as it passes over the net. The rod is preferably three feet long and each section is one foot in length. Support for the rod is achieved by an extension rod connected end-to-end with the marked rod and inserted through plural interstices of the net. An extension rod may be secured to the top of the marked rod to suspend an apertured target member used for practicing serves. One of the marked/support rods may be provided with two pairs of apertures which cooperate with respective support pins to secure the rod to a chain link fence.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
118 words
A tennis training apparatus comprising: a standard tennis net of the type having interwoven members and multiple interstices between said interwoven members, said net being tautly supported at its ends to extend across a playing area; an elongated rod having first and second ends, said rod being inserted through plural vertically aligned interstices of said net with said first end abutting the ground to support the rod by means of the net and the ground in a vertical orientation, said rod having an upper length portion extending entirely above said net and terminating at said second end; wherein said upper length portion is subdivided into a plurality of successive length segments, each length segment having a different color.
Claim 2
Dependent Claim
118 words
A tennis training apparatus comprising: a standard tennis net of the type having interwoven members and multiple interstices between said interwoven members, said net being tautly supported at its ends to extend across a playing area; an elongated rod having first and second ends, said rod being inserted through plural vertically aligned interstices of said net with said first end abutting the ground to support the rod by means of the net and the ground in a vertical orientation, said rod having an upper length portion extending entirely above said net and terminating at said second end; wherein said upper length portion is subdivided into a plurality of successive length segments, each length segment having a different color.
Claim 3
Dependent Claim
37 words
The tennis training apparatus according to claim 1 wherein said upper length portion is approximately three feet long, and wherein said plurality of length segments are three in number, each length segment being approximately one foot long.
Claim 4
Dependent Claim
51 words
The tennis training apparatus according to claim 1 wherein said rod has two separable length sections, a first section corresponding to said upper length portion, and a second section serving as a support portion, said apparatus further comprising coupling means for securing said first and second sections together in end-to-end orientation.
Claim 5
Dependent Claim
79 words
The tennis training apparatus according to claim 1 further comprising: an extension rod having first and second ends; means securing said first end of said extension rod to said second end of said elongated rod such that the extension rod extends radially outward and away from said elongated rod; a target member having an aperture defined therein which is larger than a standard tennis ball; and means suspending said target member from said first end of said extension rod.
Claim 6
Dependent Claim
31 words
The tennis training apparatus according to claim 4 further comprising means for selectively adjusting the height at which said apertured member is suspended from said first end of said extension rod.
Claim 7
Dependent Claim
41 words
The tennis training apparatus according to claim 4 further comprising means securing said target member to said elongated rod for preventing rotation of said target member about a vertical axis and thereby assuring that the target member faces a specified direction.
Claim 8
Dependent Claim
53 words
The tennis training apparatus according to claim 1 wherein said elongated rod is selectively removable from said net and repositionable at multiple positions along said net by interweaving the elongated rod through other vertically aligned interstices of said net so as to rest said first end of said elongated rod on the ground.
