Abstract
Abstract An exercise apparatus for aerobic conditioning of a person having a flexible rod over which the person must jump in accordance with a rhythmic cadence. A variable speed control device controls the speed of movement of the rod. A light beam may be utilized to replace the flexible rod. The user jumps onto a shock absorbing medium to reduce the shock to the exoskeleton system.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
148 words
An exercise apparatus for aerobic conditioning of a person comprising: a rod having opposite ends, the rod creating a barrier over which the person must jump; a variable speed motor; a motor controller operatively connected to the variable speed motor for controlling the motor speed; a mechanical linkage connecting the motor to one end of the rod, the motor and mechanical linkage causing the rod to reciprocate across a jump zone defined by the area beneath the rod as it reciprocates, the motor controller varying the motor speed and the speed of reciprocation of the rod with the person jumping over the rod in a rhythmic cadance which corresponds to the timing interval of the reciprocation of the rod as it moves back and forth across the jump zone; and a light source associated with the rod which can be seen by the person regardless of ambient light.
Claim 2
Dependent Claim
148 words
An exercise apparatus for aerobic conditioning of a person comprising: a rod having opposite ends, the rod creating a barrier over which the person must jump; a variable speed motor; a motor controller operatively connected to the variable speed motor for controlling the motor speed; a mechanical linkage connecting the motor to one end of the rod, the motor and mechanical linkage causing the rod to reciprocate across a jump zone defined by the area beneath the rod as it reciprocates, the motor controller varying the motor speed and the speed of reciprocation of the rod with the person jumping over the rod in a rhythmic cadance which corresponds to the timing interval of the reciprocation of the rod as it moves back and forth across the jump zone; and a light source associated with the rod which can be seen by the person regardless of ambient light.
Claim 3
Dependent Claim
27 words
The apparatus of claim 1 and further comprising a jump pad positioned beneath the rod and in the jump zone on which the person stands and jumps.
Claim 4
Dependent Claim
16 words
The apparatus of claim 2 and further comprising a housing which contains the variable speed control.
Claim 5
Dependent Claim
26 words
The apparatus of claim 1 wherein the motor and mechanical linkage causes the rod to reciprocate back and forth in an arc across the jump zone.
Claim 6
Dependent Claim
30 words
The apparatus of claim 1 wherein the light source is a light at the other end of the rod which can be seen by the person regardless of ambient light.
Claim 7
Dependent Claim
24 words
The apparatus of claim 1 wherein the light source is a luminescent rod which can be seen by the person regardless of ambient light.
Claim 8
Dependent Claim
12 words
The apparatus of claim 1 wherein the rod is a flexible rod.
Claim 9
Dependent Claim
37 words
The apparatus of claim 1 and further comprising a timer device to control the time during which the motor will be energized and in turn the length of time the person will be jumping over the rod.
Claim 10
Dependent Claim
89 words
An exercise apparatus for aerobic conditioning comprising: a flexible rod creating a barrier over which a person must jump; a variable speed motor; control means connected to the motor for controlling the speed of the motor; linkage means operatively connecting the flexible rod to the variable speed motor; and pivot means fixing the flexible rod so that the rod can move in an arc about the pivot means, the arc defining a jump zone, whereby the person jumps over the flexible rod as it moves across the jump zone.
Claim 11
Dependent Claim
89 words
An exercise apparatus for aerobic conditioning comprising: a flexible rod creating a barrier over which a person must jump; a variable speed motor; control means connected to the motor for controlling the speed of the motor; linkage means operatively connecting the flexible rod to the variable speed motor; and pivot means fixing the flexible rod so that the rod can move in an arc about the pivot means, the arc defining a jump zone, whereby the person jumps over the flexible rod as it moves across the jump zone.
Claim 12
Dependent Claim
22 words
The apparatus of claim 9 wherein the motor and linkage cause the rod to reciprocate back and forth across the jump zone.
Claim 13
Dependent Claim
97 words
An exercise apparatus for aerobic conditioning comprising: a flexible rod creating a barrier over which a person must jump; a linear variable speed motor, the motor reciprocating up and back across a predetermined area; a jump zone defined by the path of the flexible rod as it moves up and back across the predetermined area; control means connected to the motor for controlling the speed of the motor; and coupling means for connecting the flexible rod to the linear variable speed motor, whereby the person jumps over the flexible rod as it moves across the jump zone.
Claim 14
Dependent Claim
97 words
An exercise apparatus for aerobic conditioning comprising: a flexible rod creating a barrier over which a person must jump; a linear variable speed motor, the motor reciprocating up and back across a predetermined area; a jump zone defined by the path of the flexible rod as it moves up and back across the predetermined area; control means connected to the motor for controlling the speed of the motor; and coupling means for connecting the flexible rod to the linear variable speed motor, whereby the person jumps over the flexible rod as it moves across the jump zone.
Claim 15
Dependent Claim
22 words
The apparatus of claim 11 and further comprising a timer device to control the time during which the motor will be energized.
Claim 16
Dependent Claim
91 words
An exercise apparatus for aerobic conditioning comprising: a reciprocating impact striking means for creating a barrier over which a person must jump; a jump zone defined by the area beneath the impact striking means as it reciprocates, the person jumping over the impact striking means and staying in the jump zone; a variable speed motor connected to the impact striking means; and a variable timing control device for establishing timing intervals, whereby in each timing interval the person jumps over the impact striking means each time it passes beneath the person.
Claim 17
Dependent Claim
91 words
An exercise apparatus for aerobic conditioning comprising: a reciprocating impact striking means for creating a barrier over which a person must jump; a jump zone defined by the area beneath the impact striking means as it reciprocates, the person jumping over the impact striking means and staying in the jump zone; a variable speed motor connected to the impact striking means; and a variable timing control device for establishing timing intervals, whereby in each timing interval the person jumps over the impact striking means each time it passes beneath the person.
