Abstract
Abstract The disclosure describes a physiotherapeutic self-exerciser which enables a patient to apply himself traction to the muscles or tendons of his feet; the exerciser includes a sabot to which the patient's foot is attached and a pair of levers which are manually engageable by the patient; the patient gradually applies his weight to the levers connected to the sabot, thereby exerting an upward tension of the sabot, and the latter, combined with the flexing of the patient's knee, exerts a predetermined traction on the tendon or muscle to be treated.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
181 words
A physiotherapeutic self-exerciser to enable a patient to apply himself traction to the muscles or tendons of his foot comprising: a base; a sabot pivotably mounted relative to said base, said sabot adapted to fixedly receive the foot of the patient, said sabot having a toe end and an ankle end; support means for supporting said self-exerciser, and associated with said base; lever means mounted to said support means and being articulatable relative to said support, said lever means having one end actuatable by the patient so that the latter may use his weight to articulate said lever means; and tie means connecting the other end of said lever means to said toe end of said lever means whereby the patient, by gradually applying his weight to the lever means, exerts a tension of the sabot, said tension exerting traction to the foot muscle or tendon to be treated; said lever means consisting essentially of a pair of levers in scissor-like arrangement, each lever having one end manually engageable by the patient and the other end connected to said tie means.
Claim 2
Dependent Claim
181 words
A physiotherapeutic self-exerciser to enable a patient to apply himself traction to the muscles or tendons of his foot comprising: a base; a sabot pivotably mounted relative to said base, said sabot adapted to fixedly receive the foot of the patient, said sabot having a toe end and an ankle end; support means for supporting said self-exerciser, and associated with said base; lever means mounted to said support means and being articulatable relative to said support, said lever means having one end actuatable by the patient so that the latter may use his weight to articulate said lever means; and tie means connecting the other end of said lever means to said toe end of said lever means whereby the patient, by gradually applying his weight to the lever means, exerts a tension of the sabot, said tension exerting traction to the foot muscle or tendon to be treated; said lever means consisting essentially of a pair of levers in scissor-like arrangement, each lever having one end manually engageable by the patient and the other end connected to said tie means.
Claim 3
Dependent Claim
36 words
A self-exerciser as defined in claim 1, further comprising limiting means mounted at the toe end of the sabot engaging the patient's leg to prevent the ankle from exceeding a prescribed angle of rotation during exercising.
Claim 4
Dependent Claim
46 words
A self-exerciser as defined in claim 2, wherein said limiting means comprise an arc-shaped member having one end fixedly mounted to the toe end of said sabot and the opposite upper end adapted to contact the patient's leg; said member consisting of two telescopically engaged parts.
Claim 5
Dependent Claim
36 words
A self-exerciser as defined in claim 3, means for adjusting the relative position of said parts to one another to provide various angles of rotation of the ankle; one of said parts displaying a scale thereon.
Claim 6
Dependent Claim
20 words
A self-exerciser as defined in claim 1, comprising means for measuring the traction exerted on the patients tendons during exercising.
Claim 7
Dependent Claim
58 words
A self-exerciser as defined in claim 5, wherein said measuring means include a cantilevered beam attached to the toe end of the sabot; said tie means having the lower end thereof attached to said beam; a dial; and means on said beam for registering on said dial the displacement of said beam when said lever means is activated
Claim 8
Dependent Claim
177 words
A physiotherapeutic self-exerciser to enable a patient to apply himself traction to the muscles or tendons of his foot comprising: a base; a sabot pivotably mounted relative to said base, said sabot adapted to fixedly receive the foot of the patient, said sabot having a toe end and an ankle end; support means for supporting said self-exerciser, and associated with said base; lever means mounted to said support means and being articulatable relative to said support, and lever means having one end actuatable by the patient so that the latter may use his weight to articulate said lever means; and tie means connecting the other end of said lever means to said toe end of said lever means whereby the patient, by gradually applying his weight to the lever means, exerts a tension of the sabot, said tension exerting traction to the foot muscle or tendon to be treated; and limiting means mounted at the toe end of the sabot engaging the patient's leg to prevent the ankle from exceeding a prescribed angle of rotation during exercising.
Claim 9
Dependent Claim
177 words
A physiotherapeutic self-exerciser to enable a patient to apply himself traction to the muscles or tendons of his foot comprising: a base; a sabot pivotably mounted relative to said base, said sabot adapted to fixedly receive the foot of the patient, said sabot having a toe end and an ankle end; support means for supporting said self-exerciser, and associated with said base; lever means mounted to said support means and being articulatable relative to said support, and lever means having one end actuatable by the patient so that the latter may use his weight to articulate said lever means; and tie means connecting the other end of said lever means to said toe end of said lever means whereby the patient, by gradually applying his weight to the lever means, exerts a tension of the sabot, said tension exerting traction to the foot muscle or tendon to be treated; and limiting means mounted at the toe end of the sabot engaging the patient's leg to prevent the ankle from exceeding a prescribed angle of rotation during exercising.
Claim 10
Dependent Claim
30 words
A self-exerciser as defined in claim 1 or 7, further comprising means on said sabot for adjusting the connection of said tie means to said toe end of said sabot.
Claim 11
Dependent Claim
37 words
A self-exerciser as defined in claim 1 or 7, wherein said support means include a horizontally extending pivot disposed adjacent the ankle end of said sabot and in substantially vertical alignment with the ankle of the patient.

A self-exerciser as defined in claims 1 and 7, further comprising fastening means secured to said sabot for solidly attaching the foot of the patient to the sabot.
Claim 13
Dependent Claim
46 words
A self-exerciser as defined in claim 7 wherein said limiting means comprise an arc-shaped member having one end fixedly mounted to the toe end of said sabot and the opposite upper end adapted to contact the patient's leg; said member consisting of two telescopically engaged parts.
Claim 14
Dependent Claim
36 words
A self-exerciser as defined in claim 11, means for adjusting the relative position of said parts to one another to provide various angles of rotation of the ankle; one of said parts displaying a scale thereon.
Claim 15
Dependent Claim
