Abstract
Abstract A muscle stretching apparatus for stretching the lower body muscles of a person straddling two hinged body-support platforms. A motor-driven extension tube connects at each end to the platform and contracts or expands the angle between the platforms while straddled by a person. The apparatus includes cycling capabilities, angle measurement means and timer means.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
146 words
A muscle stretching apparatus for stretching the lower body muscles of a user when in a straddling or lying position, said apparatus comprising: (a) two body-support platforms connected end-to-end at an angle and arranged such that a user lies or sits on top sides of both platforms; (b) a motor-driven extension tube connected at each end to undersides of the respective body-support platforms and adapted to contract or expand the angle between the platforms with respect to each other while being occupied by a user; (c) control means for causing contraction or expansion of the motor-driven extension tube; and (d) angle measurement means connected to the respective body-support platforms for permitting the user to determine the angle between the respective platforms before and after expansion or contraction thereof, whereby upon expansion or contraction of the angle between the platforms, the user's muscles are stretched or relaxed.
Claim 2
Dependent Claim
146 words
A muscle stretching apparatus for stretching the lower body muscles of a user when in a straddling or lying position, said apparatus comprising: (a) two body-support platforms connected end-to-end at an angle and arranged such that a user lies or sits on top sides of both platforms; (b) a motor-driven extension tube connected at each end to undersides of the respective body-support platforms and adapted to contract or expand the angle between the platforms with respect to each other while being occupied by a user; (c) control means for causing contraction or expansion of the motor-driven extension tube; and (d) angle measurement means connected to the respective body-support platforms for permitting the user to determine the angle between the respective platforms before and after expansion or contraction thereof, whereby upon expansion or contraction of the angle between the platforms, the user's muscles are stretched or relaxed.
Claim 3
Dependent Claim
92 words
Apparatus according to claim 1, wherein said angle measurement means comprises a rotary resistor attached to the underside of one body-support platform and having a first connection rod connected at one end thereof, said first connection rod being attached at the opposite end thereof to a second connection rod at one end thereof, said second connection rod being secured at the opposite end thereof to the underside of the second body-support platform, said first connection rod being arranged to rotate said rotary resistor when the angle between the respective platforms is changed.
Claim 4
Dependent Claim
20 words
Apparatus according to claim 1, further comprising a control stick which activates expansion and contraction of said motor-driven extension tube.
Claim 5
Dependent Claim
25 words
Apparatus according to claim 1, further comprising timer means for permitting measurement of the amount of time the angle between said body-support platforms remains constant.
Claim 6
Dependent Claim
25 words
Apparatus according to claim 1, further comprising means for emitting an audio signal at the end of a predetermined time period the angle remains constant.
Claim 7
Dependent Claim
24 words
Apparatus according to claim 1, further comprising handle means for support of a user and connected to at least one of said body-support platforms.
Claim 8
Dependent Claim
19 words
Apparatus according to claim 1, further comprising display means permitting display of measurements determined by said angle measurement means.
Claim 9
Dependent Claim
29 words
Apparatus according to claim 1, further comprising means mounted on the lowermost portions of said body-support platforms permitting said body-support platforms to move across a floor or other surface.
