Abstract
Abstract A vertical leap measuring apparatus and method is illustrated including a series of vertically spaced electric pressure-sensitive switches and a device for recording an indication reflecting height reached both from a standing position and subsequently from a vertical leap, wherein the difference between the two indications of height reached is calculated to determine the height of the vertical leap.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
97 words
Apparatus for measuring the height of a vertical leap comprising: a series of vertically spaced pressure-sensitive switches; means for first recording an indication reflecting a height reached by a person upwardly extending one hand and engaging one of said pressure-sensitive switches from a standing position and subsequently recording a height from said person's upwardly extending hand engaging another one of said switches during a vertical leap; and electrical measurement means coupled to said means for recording adjacent said pressure-sensitive switches to calculate the difference between said indications so as to measure the height of the vertical leap.
Claim 2
Dependent Claim
97 words
Apparatus for measuring the height of a vertical leap comprising: a series of vertically spaced pressure-sensitive switches; means for first recording an indication reflecting a height reached by a person upwardly extending one hand and engaging one of said pressure-sensitive switches from a standing position and subsequently recording a height from said person's upwardly extending hand engaging another one of said switches during a vertical leap; and electrical measurement means coupled to said means for recording adjacent said pressure-sensitive switches to calculate the difference between said indications so as to measure the height of the vertical leap.
Claim 3
Dependent Claim
22 words
The apparatus set forth in claim 1 wherein said switches include vertically spaced indicia marking the respective pressure-sensitive portions of said switches.
Claim 4
Dependent Claim
29 words
The apparatus set forth in claim 1 wherein said means for recording an indication reflecting the height reached includes a digital display for displaying said calculated vertical leap measurement.
Claim 5
Dependent Claim
16 words
The apparatus set forth in claim 1 including means for mounting said measuring apparatus comprising brackets.
Claim 6
Independent Claim
108 words
A method of measuring the height of a vertical leap comprising the steps of: mounting vertically a series of pressure-sensitive switches; recording engagement of one of said switches by a person's upwardly extended hand from a standing position so as to produce a first indication of height reached; recording engagement of another one of said switches by said person's upwardly extended hand during a vertical leap so as to produce a second indication of height reached; and electrically calculating the difference between said first and said second indications so as to determine the height of the vertical leap so as to measure the height of the vertical leap.
Claim 7
Independent Claim
108 words
A method of measuring the height of a vertical leap comprising the steps of: mounting vertically a series of pressure-sensitive switches; recording engagement of one of said switches by a person's upwardly extended hand from a standing position so as to produce a first indication of height reached; recording engagement of another one of said switches by said person's upwardly extended hand during a vertical leap so as to produce a second indication of height reached; and electrically calculating the difference between said first and said second indications so as to determine the height of the vertical leap so as to measure the height of the vertical leap.
