Abstract
Abstract A device for stretching of an anatomical portion of the human body, thereafter holding such body portion in a stretched position for a period of time and thereafter returning such body portion to its original, unstretched position is disclosed. A horizontal base platform is provided with a generally vertical support member. The generally vertical support member is freely movable in a first direction with respect to the base platform member but is restricted from movement in a second direction opposite the first direction. Thus, the user of the device may position the subject anatomical body part in contact with the generally vertical support member and thereafter move the support member in the first direction until such time as the subject body part is optimally or maximally stretched. Thereafter the support member will hold the subject body part in the stretched position until such time as the user releases a uni-directional mechanism which permits the support member to move in the second direction opposite the first direction, thereby permitting the subject body part to return to its original, unstretched position. The support member is restricted substantially between a generally vertical position and locked positions forming an acute angle with the horizontal base.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
243 words
An exercise device for stretching an anatomical portion of the human body, said device comprising: a generally horizontal base platform sized to support the legs of a user thereon in a generally contiguous orientation; a back rest pivotally attached to said base platform for pivotal movement substantially restricted between a generally vertical orientation relative said base platform to pivotal orientations forming an acute angle to said base platform; a uni-directional ratchet mechanism cooperating with said base platform and said backrest for permiting pivotal movement of said backrest in a first direction toward said base platform while prohibiting pivotal movement of said backrest in a second direction opposite said first direction; a pair of armrests pivotally attached to said backrest and extending outwardly therefrom in a plane generally parallel to said base platform; a handgrip mounted to each of said pair of armrests adapted to be grasped in the hands of a user; and actuation means positioned adjacent at least one of said handgrips to selectively disengage said uni-directional ratchet mechanism, said uni-directional ratchet mechanism enabling the user to pivotally move said backrest in said first direction to stretch an anatomical portion of the user's body to a desired position, and thereafter, hold said body portion in such stretched position until such time as said uni-directional ratchet mechanism is disengaged by manipulation of the actuation means, thereby permitting the user to return said backrest to its generally vertical orientation thereby relaxing said body portion.
Claim 2
Dependent Claim
243 words
An exercise device for stretching an anatomical portion of the human body, said device comprising: a generally horizontal base platform sized to support the legs of a user thereon in a generally contiguous orientation; a back rest pivotally attached to said base platform for pivotal movement substantially restricted between a generally vertical orientation relative said base platform to pivotal orientations forming an acute angle to said base platform; a uni-directional ratchet mechanism cooperating with said base platform and said backrest for permiting pivotal movement of said backrest in a first direction toward said base platform while prohibiting pivotal movement of said backrest in a second direction opposite said first direction; a pair of armrests pivotally attached to said backrest and extending outwardly therefrom in a plane generally parallel to said base platform; a handgrip mounted to each of said pair of armrests adapted to be grasped in the hands of a user; and actuation means positioned adjacent at least one of said handgrips to selectively disengage said uni-directional ratchet mechanism, said uni-directional ratchet mechanism enabling the user to pivotally move said backrest in said first direction to stretch an anatomical portion of the user's body to a desired position, and thereafter, hold said body portion in such stretched position until such time as said uni-directional ratchet mechanism is disengaged by manipulation of the actuation means, thereby permitting the user to return said backrest to its generally vertical orientation thereby relaxing said body portion.
Claim 3
Dependent Claim
27 words
The device of claim 1 including means for adjusting the position of said handgrips relative to said armrests so as to accomodate users of varying body size.
Claim 4
Dependent Claim
23 words
The device of claim 2 further comprising an elongate support member extending between each of said pair of armrests and said base platform.
Claim 5
Dependent Claim
66 words
The device of claim 3 wherein said uni-directional ratchet mechanism is mounted on said base platform member adjacent to at least one of said support members, said uni-directional ratchet mechanism comprising an arcuate ratchet surface having a series of ratchet teeth and a pawl pivotally attached to said at least one support member, said pawl being downwardly biased so as to frictionally engage the ratchet teeth.
Claim 6
Dependent Claim
83 words
The device of claim 4 wherein the teeth of said arcuate ratchet surface are cammed in a first forward direction so as to permit said pawl to frictionally glide over the surfaces of said teeth, thereby permitting said support member to bend forward in said first direction, said pawl being further adapted to directly frictionally engage the opposite sides of said cammed teeth, thereby preventing reverse movement of the device until such time as said pawl is removed from contact with said teeth.
Claim 7
Dependent Claim
49 words
The device of claim 5 wherein said pawl is operatively connected to said actuation means such that manipulation of said actuation means results in retraction of said pawl from frictional contact with said ratchet teeth, thereby permitting movement of said device in said second direction opposite said first direction.
