Abstract
Abstract A double acting exerciser has a tubular body; a first compressible resilient member disposed within the tubular body and prevented from passing from the first end thereof by a holding member; a rod member having an abutting member on its first end which abuts against the first end of the first resilient member, the second end of the first resilient member abutting against the holding member; the rod member having a second resilient member about it, having a cap member for the second end of the tubular body about it and also affixed to the second end of the body member; the rod member having a handle member affixed at or near its second end; the tubular body having a second handle member affixed at or near its first end. In a presently preferred mode, the tubular body has a base member fixable to its first end. The exerciser is useful to carry out an extraordinary number and kind of body exercising and building exercises.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
222 words
A double acting exerciser suited for exercising of the human body comprising: (a) a tubular body having a first holding member on its first end; (b) a first compressible resilient member disposed within the tubular body and prevented from passing from the first end thereof by the first holding member; (c) a rod member having an abutting member on its first end which abuts against the first end of the first resilient member within the tubular body; (d) a second compressible resilient member positioned in an annulus between the rod member and the tubular body; (e) a second holding member positioned about the rod member and affixed to the second end of the tubular body such as to permit reciprocating motion in two directions of the rod member therethrough and to prevent movement of the second compressible resilient member beyond the second end of the tubular body; (f) a first elongated handle member adapted for gripping by a human hand affixed at or near the second end of the rod member; (g) a second elongated handle member affixed at or near the first end of the tubular body; such that movement of the handles together and movement of the handles apart both result in a stroke of suitable length and of suitable resistance in both directions for exercising of the human body.
Claim 2
Dependent Claim
222 words
A double acting exerciser suited for exercising of the human body comprising: (a) a tubular body having a first holding member on its first end; (b) a first compressible resilient member disposed within the tubular body and prevented from passing from the first end thereof by the first holding member; (c) a rod member having an abutting member on its first end which abuts against the first end of the first resilient member within the tubular body; (d) a second compressible resilient member positioned in an annulus between the rod member and the tubular body; (e) a second holding member positioned about the rod member and affixed to the second end of the tubular body such as to permit reciprocating motion in two directions of the rod member therethrough and to prevent movement of the second compressible resilient member beyond the second end of the tubular body; (f) a first elongated handle member adapted for gripping by a human hand affixed at or near the second end of the rod member; (g) a second elongated handle member affixed at or near the first end of the tubular body; such that movement of the handles together and movement of the handles apart both result in a stroke of suitable length and of suitable resistance in both directions for exercising of the human body.
Claim 3
Dependent Claim
91 words
The exerciser of claim 1 wherein a base member having a generally flattened surface is fixable to the first end of the tubular body with its axes of flattening generally perpendicular to the long axis of the tubular body, and of suitable dimensions of flattening for positioning of human feet thereon; and wherein the axis of elongation of both the first elongated handle member and the second elongated handle member intersect the long axis of the rod member and the long axis of the tubular body at a substantially right angle.
Claim 4
Dependent Claim
28 words
The exerciser of claim 2 wherein the first handle member is suitable for gripping with both hands, with one hand grip on each side of the rod member.
Claim 5
Dependent Claim
119 words
The exerciser of claim 1 wherein the tubular body is cylindrical, the first compressible resilient member comprises a coil spring, the second compressible resilient member comprises a coil spring, the second compressible resilient member is positioned about the rod member, the second holding member is a cap for the tubular body having a centered hole through which the rod member passes, the first and second elongated handle members project from the long axis of the tubular member in the same direction, the axis of elongation of the first handle member and the axis of elongation of the second handle member are both at a right angle to the long axis of both the tubular member and the rod member.
Claim 6
Dependent Claim
53 words
The exerciser of claim 4 wherein a generally flattened base member suitable for standing upon is fixable to the first end of the tubular body with its axes of flattening generally perpendicular to the long axis of the tubular body, and of suitable dimensions along its axes of flattening for positioning human feet.
Claim 7
Dependent Claim
33 words
The exerciser of claim 5 wherein the first and second compressible resilient members comprise a selection of interchangable coil springs of varying stiffness and the cap is readily detachable from the tubular body.
Claim 8
Dependent Claim
76 words
The exerciser of claim 6 wherein a plurality of coil springs comprise the first compressible resilient member, a plurality of coil springs comprise the second compressible resilient member, a selection of coil springs of varying stiffness is provided for adjusting the compressibility of the exerciser to match the strength of the user, and the cap has female threads matable with male threads on the second end of the tubular body for easy interchange of the springs.
Claim 9
Dependent Claim
28 words
The exerciser of claim 7 wherein the first handle member comprises opposed handles suitable for gripping with both hands when the users feet are planted on the base.
Claim 10
Dependent Claim
