Abstract
Abstract Heart pulse rate is measured by use of a pair of handle grips (12), (14) for a bicycle handle (16), and the like, one of which grips (12) provides a conductive contact (22), (23) between one of the hands of a user of the apparatus and an associated end of the handlebar. The other of the hand grips (14) includes a pair of contacts (32), (34) arranged for being simultaneously engaged by the other hand of the user of the device, with a further contact (30) being disposed for electrical connection to an end of the handlebar associated with the other of the hand grips. In this manner, the handlebar serves to complete a circuit through the user's body and enables a pulse monitoring apparatus (26) preferably provided on one of the hand grips (14) to detect and display the pulse rate of the user of the apparatus.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
182 words
A heart pulse monitoring apparatus for attachment to the handlebar of an exercising device for measurement of the pulse rate of a user, comprising: a first hand grip for attachment to one end of the handlebar of a bicycle or stationary exercise device and having first means for completing an electrical circuit from a hand of said user when gripping said first hand grip to a conductive part of said handlebar; a second hand grip including a second means for electrically contacting the other end of said handlebar, said second means being electrically isolated from the other hand of said user when gripping said second hand grip, third and fourth means disposed upon said second hand grip in spaced apart relationship and adapted to electrically engage said other hand of said user when gripping said second hand grip; and signal monitoring means electrically coupled to said second, third and fourth means for measuring electric pulses created in the body of said user whose hands are holding said first and second hand grips and for indicating the heart pulse rate of such body.
Claim 2
Dependent Claim
182 words
A heart pulse monitoring apparatus for attachment to the handlebar of an exercising device for measurement of the pulse rate of a user, comprising: a first hand grip for attachment to one end of the handlebar of a bicycle or stationary exercise device and having first means for completing an electrical circuit from a hand of said user when gripping said first hand grip to a conductive part of said handlebar; a second hand grip including a second means for electrically contacting the other end of said handlebar, said second means being electrically isolated from the other hand of said user when gripping said second hand grip, third and fourth means disposed upon said second hand grip in spaced apart relationship and adapted to electrically engage said other hand of said user when gripping said second hand grip; and signal monitoring means electrically coupled to said second, third and fourth means for measuring electric pulses created in the body of said user whose hands are holding said first and second hand grips and for indicating the heart pulse rate of such body.
Claim 3
Dependent Claim
30 words
A heart pulse monitoring apparatus as recited in claim 1 wherein said third and fourth means are spaced apart metallic bands circumscribing the external surface of said second hand grip.
Claim 4
Dependent Claim
26 words
A heart pulse monitoring apparatus as recited in claim 1 wherein said second hand grip includes means forming a housing for containing said signal monitoring means.
Claim 5
Dependent Claim
35 words
A heart pulse monitoring apparatus as recited in claim 3 wherein said signal monitoring means includes a digital display indicator and said housing includes a window formed therein through which said indicator may be viewed.
Claim 6
Dependent Claim
46 words
A heart pulse monitoring apparatus as recited in claims 1, 2, 3 or 4 wherein said signal monitoring means includes means for detecting the R-waves generated by the body whose hands are holding said first and second hand grips and for generating electrical pulses corresponding thereto.
Claim 7
Dependent Claim
41 words
A heart pulse monitoring apparatus as recited in claim 5 wherein said signal monitoring means further includes means for determining the number of said electrical pulses generated per a predetermined unit of time and for generating a rate signal corresponding thereto.
Claim 8
Dependent Claim
35 words
A heart pulse monitoring apparatus as recited in claim 6 wherein said signal monitoring means further includes a signal conversion means for converting said rate signal into an electrical signal suitable for driving an indicator.
Claim 9
Dependent Claim
59 words
A heart pulse monitoring apparatus as recited in claim 6 wherein said means for determining includes a clock for generating clock pulses, a counter, and a gate responsive to said electrical pulses and operative to enable said counter to count the number of clock pulses occurring between a predetermined number of said electrical pulses and develop said rate signal.
Claim 10
Dependent Claim
35 words
A heart pulse monitoring apparatus as recited in claim 8 wherein said signal monitoring means further includes a signal conversion means for converting said rate signal into an electrical signal suitable for driving an indicator.
Claim 11
Dependent Claim
21 words
A heart pulse monitoring apparatus as recited in claim 9 wherein said signal monitoring means further includes a self-contained power supply.
