Abstract
Abstract An energy converting exercise device comprising a housing and a shaft extending therethrough for frictionally resisted axial movement of the shaft relative to the housing. The housing includes adjustable braking means to allow the user to vary the level of resistance to such relative axial movement, and operatively associated with the shaft are readout means to indicate to the user in units of applied force the instantaneous level of resistance effective as he moves the shaft axially relative to the housing.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
93 words
An exerciser device comprising an elongate cylindrical housing; a shaft slidably mounted in said housing and extending therethrough, said shaft and said housing being substantially coaxial; bushing means adjacent each of the ends of said housing to support said shaft in spaced relationship to the wall of said housing; and adjustable means in operative relationship to said housing for selctively applying a force against said shaft in a direction substantially normal to the axis thereof, whereby the degree of frictional resistance to movement of said shaft relative to said housing may be varied.
Claim 2
Dependent Claim
93 words
An exerciser device comprising an elongate cylindrical housing; a shaft slidably mounted in said housing and extending therethrough, said shaft and said housing being substantially coaxial; bushing means adjacent each of the ends of said housing to support said shaft in spaced relationship to the wall of said housing; and adjustable means in operative relationship to said housing for selctively applying a force against said shaft in a direction substantially normal to the axis thereof, whereby the degree of frictional resistance to movement of said shaft relative to said housing may be varied.
Claim 3
Dependent Claim
25 words
The device of claim 1 wherein said adjustable means includes a collar on said shaft adapted to accept said force for transfer to said shaft.
Claim 4
Dependent Claim
19 words
The device of claim 1 wherein said adjustable means includes rotatable means threadedly engaging the wall of said housing.
Claim 5
Dependent Claim
18 words
The device of claim 3 in which yielding means are interposed between said rotatable means and said shaft.
Claim 6
Dependent Claim
41 words
The device of claim 1 wherein said housing includes means depended therefrom and adapted to accept a driving force at an effective point of application eccentric from said shaft, said driving force tending to move said housing relative to said shaft.
Claim 7
Dependent Claim
43 words
The device of claim 5 in which the plane defined by the axis of said shaft and the effective point of application of said driving force is substantially normal to the direction of the force applied to said shaft by said adjustable means.
Claim 8
Dependent Claim
26 words
The device of claim 1 wherein said shaft includes means depended therefrom adapted to accept a force tending to move said shaft relative to said housing.
Claim 9
Dependent Claim
46 words
The device of claim 1 wherein said housing and said shaft include means depended therefrom and adapted respectively to accept equal and opposite forces whereby said housing and said shaft may be moved relative to each other by the application of such equal and opposite forces.
Claim 10
Dependent Claim
13 words
The device of claim 8 in which said depended means are hand grips.
Claim 11
Dependent Claim
23 words
The device of claim 8 in which said depended means are yokes adapted to engage the limbs of a person employing the exerciser.
Claim 12
Dependent Claim
62 words
An exerciser device comprising a shaft; a housing slidably mounted on said shaft, said housing including means for selectively varying the degree of frictional engagement between said shaft and said housing; and applied force indicating means operatively associated with said shaft whereby the level of a force tending to cause axial movement of said shaft relative to said housing may be observed.
Claim 13
Dependent Claim
62 words
An exerciser device comprising a shaft; a housing slidably mounted on said shaft, said housing including means for selectively varying the degree of frictional engagement between said shaft and said housing; and applied force indicating means operatively associated with said shaft whereby the level of a force tending to cause axial movement of said shaft relative to said housing may be observed.
Claim 14
Dependent Claim
86 words
The device of claim 11 in which said force indicating means includes an elongate housing mounted on said shaft and adapted for free axial movement relative thereto; a stop collar fixedly attached to said shaft; and yielding means disposed between said stop collar and said elongate housing whereby axial displacement of said shaft is resisted by said yielding means to a degree substantially commensurate with the level of a force applied to said elongate housing tending to move said elongate housing axially relative to said shaft.
Claim 15
Dependent Claim
90 words
The device of claim 11 in which said applied force indicating means includes abutment means unitary with said shaft; a tubular housing slidably mounted on said shaft; yielding means interposed between said abutment means and said tubular housing; a collar fixedly attached to said shaft in telescoping relationship to said tubular housing; and at least one scale on said tubular housing arranged and graduated so as to register by reference to a point on said collar the amount of force causing said yielding means to deflect to a given extent.
Claim 16
Dependent Claim
54 words
The device of claim 11 in which said housing includes means depended therefrom for application of a force substantially parallel to the axis of said shaft; and in which said applied force indicating means includes means depended therefrom for application of a force substantially equal and opposite to said force applied to said housing.
