Abstract
Abstract A pair of generally parallel spaced plastic arms are pivoted to each other at their central portions by interleaved pairs of tabs having a pivot pin extending therethrough. A light coil spring on the pivot pin biases one pair of opposite ends of the arms into light engagement for clipping them on to an ear lobe. The one pair of opposite ends have a pair of hollow bosses formed thereon, with heart beat sensors positioned in each boss. Electric wires connected to the sensors extend therefrom along the arms through channels formed in the arms. The pivot pin has heads formed at its opposite ends. Apertures are formed in these heads and an elongated strip of plastic material has its opposite ends positioned in the apertures so that the remainder of the strip of material comprises an open loop for hanging the arms off the ear of the lobe to which the arms are clipped. The strip of material has a friction fit in the apertures so the size of the loop can be adjusted by selectively pulling the ends of the strip through the apertures.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
239 words
An ear lobe clip with heart beat sensor means therein, comprising a pair of equal length plastic material pivot arms, said pair of arms facing each other in spaced and generally parallel relationship, said pair of arms having a pivotal connection with each other at their respective central portions for pivotal movement of each of their two pairs of opposite ends towards and away from each other, a spring at said pivotal connection, said spring being operative to bias one of said pair of opposite ends into light engagement with each other for clipping said one pair of opposite ends on to an ear lobe, heart beat sensor means at each of said one pair of opposite ends, wires electrically connected to each of said sensor means and extending along said arms and out therefrom at the other pair of opposite ends of said arms, adjustable means for hanging said arms off the ear of the lobe to which said arms are clipped, said adjustable means comprising a pair of apertures formed on said arms, a flexible strip of plastic material, opposite ends of said strip extending into said apertures whereby the remainder of said strip comprises an open loop for hanging said arms on said ear, and said strip opposite ends having a friction fit in said apertures to pull said opposite strip ends in either direction through said apertures to adjustably set the size of said loop.
Claim 2
Dependent Claim
239 words
An ear lobe clip with heart beat sensor means therein, comprising a pair of equal length plastic material pivot arms, said pair of arms facing each other in spaced and generally parallel relationship, said pair of arms having a pivotal connection with each other at their respective central portions for pivotal movement of each of their two pairs of opposite ends towards and away from each other, a spring at said pivotal connection, said spring being operative to bias one of said pair of opposite ends into light engagement with each other for clipping said one pair of opposite ends on to an ear lobe, heart beat sensor means at each of said one pair of opposite ends, wires electrically connected to each of said sensor means and extending along said arms and out therefrom at the other pair of opposite ends of said arms, adjustable means for hanging said arms off the ear of the lobe to which said arms are clipped, said adjustable means comprising a pair of apertures formed on said arms, a flexible strip of plastic material, opposite ends of said strip extending into said apertures whereby the remainder of said strip comprises an open loop for hanging said arms on said ear, and said strip opposite ends having a friction fit in said apertures to pull said opposite strip ends in either direction through said apertures to adjustably set the size of said loop.
Claim 3
Dependent Claim
141 words
In an ear lope clip with heartbeat sensor means as in claim 1, said pivotal connection comprising a pair of integral spaced tabs on the central portion of each of said arms, said pairs of tabs being interleaved with each other and pivot pin means extending therethrough, a pair of integral hollow bosses formed at said one pair of opposite ends, said sensor means being positioned in said bosses, lengthwise extending channels formed in the opposite inner facing sides of said arms, said channels being in communication with the interior of said bosses and said wires extending from said sensor means along said arms in said channels, and said spring being coiled about said pivot pin means and having its opposite ends bearing against said other pair of opposite ends to bias said one pair of opposite ends towards each other.
Claim 4
Dependent Claim
73 words
In an ear lobe clip with heartbeat sensor means as in claim 2, said pivot pin means having a head formed at opposite ends thereof, said apertures being formed in said heads, and said flexible strip of plastic material comprising an elongated small diameter hollow plastic tube, and the outer dimension of said hollow tube being slightly oversize with respect to the size of said apertures to provide an adjustable friction fit therein.
