Abstract
Abstract Optical record disc handling apparatus for avoiding contamination of optical disc surfaces. A U-shaped handle supports on a first extending leg a centering post approximately midway between an inside edge of the supporting leg and the optical disc center. A remaining extending leg supports a pivotal gripping member which may be operated by the index finger. The pivotal gripping member is pivotal between a disc grasping position and disc releasing position. The centering post is advantageously spring loaded in the axial direction to permit a slight downward force to be applied to a centering hub in the disc storage package. The device is capable of being manufactured by standard injection molding techniques which are simple and economical.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
An apparatus for handling a circular record disc without contaminating a surface thereof comprising: a U-shaped handle having a first hand gripping section for grasping, and first and second extending legs spaced apart at a distance greater than a diameter of said circular record disc; a centering post supported approximately midway between said extending legs, said centering post having an outside diameter tapered for inserting in a centrally located hole in said record disc; and a displaceable grasping member displaceably connected to said first leg having an end which is displaceable from a first open position to a second closed position with respect to said second leg for grasping in cooperation with said second leg the circumference of said record disc when said centering post is received in said record disc hole.
Claim 2
Independent Claim
132 words
An apparatus for handling a circular record disc without contaminating a surface thereof comprising: a U-shaped handle having a first hand gripping section for grasping, and first and second extending legs spaced apart at a distance greater than a diameter of said circular record disc; a centering post supported approximately midway between said extending legs, said centering post having an outside diameter tapered for inserting in a centrally located hole in said record disc; and a displaceable grasping member displaceably connected to said first leg having an end which is displaceable from a first open position to a second closed position with respect to said second leg for grasping in cooperation with said second leg the circumference of said record disc when said centering post is received in said record disc hole.
Claim 3
Dependent Claim
19 words
The apparatus of claim 1 wherein said grasping member includes at an opposite end thereof a finger operable extension.
Claim 4
Dependent Claim
23 words
The apparatus of claim 1 wherein said second leg and grasping member include a felt surface for enhancing grasping of said record disc.
Claim 5
Dependent Claim
14 words
The apparatus of claim 1 wherein said centering post is supported for axial displacement.
Claim 6
Independent Claim
140 words
An apparatus for handling a circular record disc without contaminating a surface thereof comprising: a U-shaped handle having a longitudinal gripping section and first and second perpendicularly extending legs, said second leg including a lateral support arm extending towards said first leg; a centering post supported parallel to said second leg by said lateral support arm, said centering post having a tapered end for insertion into a centering hole of said record disc, the distance between said center post and a facing edge of said second leg being substantially the radius of said record disc; and, a grasping member pivotally connected to said first leg for pivotal movement with respect to said second leg, whereby said record disc may be grasped between said second leg edge and said grapsing member when said centering post is received in said record disc.
Claim 7
Independent Claim
140 words
An apparatus for handling a circular record disc without contaminating a surface thereof comprising: a U-shaped handle having a longitudinal gripping section and first and second perpendicularly extending legs, said second leg including a lateral support arm extending towards said first leg; a centering post supported parallel to said second leg by said lateral support arm, said centering post having a tapered end for insertion into a centering hole of said record disc, the distance between said center post and a facing edge of said second leg being substantially the radius of said record disc; and, a grasping member pivotally connected to said first leg for pivotal movement with respect to said second leg, whereby said record disc may be grasped between said second leg edge and said grapsing member when said centering post is received in said record disc.
Claim 8
Dependent Claim
12 words
The apparatus of claim 5 wherein said centering post is axially displaceable.
Claim 9
Dependent Claim
21 words
The apparatus of claim 5 wherein said centering post is supported to said lateral support arm by means of a spring.
Claim 10
Dependent Claim
30 words
The apparatus of claim 5 wherein said grasping member includes a finger operable extension extending towards said longitudinal gripping section for receiving an index finger to pivot said grasping member.
