Abstract
Abstract A circular disk including an elongated narrow slot or window is rotatably supported in a frame, in a generally vertical plane, with the disk being selectively rotatable to position the diametral window at any desired orientation. A mechanism is provided for producing a target which traverses the window at the rear face of the disk so that the user, viewing the disk from its front face, will follow a reciprocating target. In one form, a second concentric disk having an oval pattern disposed on only one half of the disk is rotated relatively to produce the reciprocating target through the window. In another form an endless belt, having runs parallel to the elongated window, carries a target member back and forth across the window. A second target carried on the rotating member behind the window disk, is a rotating target member which is visible at the periphery of the window disk. For binocular convergence exercises, a third target is secured to the frame with a fourth target being connected to the third target in adjustable spaced relation on a connecting flexible cord.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
184 words
Eye exercising apparatus comprising frame means defining a generally vertical front wall; a first rotor assembly mounted for rotation on said frame about an axis perpendicular to said front wall; said first rotor assembly including a disk disposed generally in the plane of said front wall; said disk being opaque and having a diametral window; means mounted at the rear of said disk movable relative thereto for producing a reciprocating target movable to and fro across said disk window, and being visible through said window from the front face of said disk; a second rotor assembly mounted for rotation on said frame at the rear of said first rotor assembly and about the same rotational axis; said second rotor assembly including means for producing a target rotatable generally in the plane of said disk adjacent to its periphery, and being visible from the front face of said disk; means for selectively rotating said first rotor assembly to position said diametral window at a selected orientation relative to said frame; means for driving said reciprocating target means; and means for driving said second rotor assembly.
Claim 2
Dependent Claim
184 words
Eye exercising apparatus comprising frame means defining a generally vertical front wall; a first rotor assembly mounted for rotation on said frame about an axis perpendicular to said front wall; said first rotor assembly including a disk disposed generally in the plane of said front wall; said disk being opaque and having a diametral window; means mounted at the rear of said disk movable relative thereto for producing a reciprocating target movable to and fro across said disk window, and being visible through said window from the front face of said disk; a second rotor assembly mounted for rotation on said frame at the rear of said first rotor assembly and about the same rotational axis; said second rotor assembly including means for producing a target rotatable generally in the plane of said disk adjacent to its periphery, and being visible from the front face of said disk; means for selectively rotating said first rotor assembly to position said diametral window at a selected orientation relative to said frame; means for driving said reciprocating target means; and means for driving said second rotor assembly.
Claim 3
Dependent Claim
54 words
Apparatus as set forth in claim 1 said reciprocating target means comprising a second disk mounted for rotation relative to said first disk and having an oval pattern on the front face thereof visible through said disk window to produce said reciprocating target; said oval pattern occupying only one half of said second disk.
Claim 4
Dependent Claim
85 words
Apparatus as set forth in claim 1 said reciprocating target means comprising first and second target pulleys mounted for rotation on said disk about axes perpendicular thereto, and being disposed on said disk adjacent to the ends of said diametral window; an endless belt carried on said pulleys having its runs parallel to and disposed on opposite sides of said diametral window; a target member mounted on said belt and overlying said window, to be carried by said belt in confronting relation with said window.
Claim 5
Dependent Claim
63 words
Apparatus as set forth in claim 3 said first rotor assembly having a hollow shaft journaled in said frame for supporting said assembly; a concentric shaft extending through said hollow shaft and non-rotatably carrying a drive pulley; belt means coupling said drive pulley and one of said target pulleys; and means coupling said concentric shaft to first drive means mounted on said frame.
Claim 6
Dependent Claim
35 words
Apparatus as set forth in claim 4 said second rotor assembly being mounted for rotation on said first rotor assembly; and means coupling said second rotor assembly to second drive means mounted on said frame.
Claim 7
Dependent Claim
16 words
Apparatus as set forth in claim 5 said first and second drive means comprising electric motors.
Claim 8
Dependent Claim
39 words
Apparatus as set forth in claim 1 said frame and said first rotor assembly disk defining an annular window adjacent to the periphery of said disk through which said rotating target is visible from the front of said device.
Claim 9
Dependent Claim
65 words
Apparatus as set forth in claim 7 said frame front wall defining a circular opening; said first rotor assembly disk being circular and opaque, and being of a diameter to define an annular space between said disk and said front wall; said annular space defining said annular window exposing said rotating target; and said second rotor assembly including a target member visible through said slot.
Claim 10
Dependent Claim
36 words
Apparatus as set forth in claim 2 said second disc having a target member fixed thereon adjacent to its periphery, exposed to view adjacent to the periphery of said first disk to provide said rotating target.
Claim 11
Dependent Claim
28 words
Apparatus as set forth in claim 1 said first rotor disk including a translucent peripheral margin; and said rotating target being exposed to view through said translucent margin.
Claim 12
Dependent Claim
53 words
Apparatus as set forth in claim 1 said frame means rotatively supporting first and second rotor assembly disks in closely spaced, generally vertical planes about a common rotative axis; means for latching said first disk in selected rotational positions in said frame; said second disk having said oval pattern visible through said window.
Claim 13
Dependent Claim
64 words
Apparatus as set forth in claim 1 a fixed target mounted on said frame; a spaced target connected to said fixed target by means of a flexible connector; and means for adjusting the position of said sighting target on said connector, to select the distance between the fixed and spaced targets, and the distance between the spaced target and the eye of the user.
Claim 14
Dependent Claim
25 words
Apparatus as set forth in claim 12 said fixed sighting target including a magnet, whereby said fixed target is magnetically secured to the device frame.
