Abstract

Abstract A posture training device includes in a mechanical-electrical embodiment thereof, an electrically conductive plate divided into two contact zones and slidable upon a support base of one housing section of the device. One end of the plate is operatively connected to a body harness cable extending around the longitudinal axis of the body from the pubis to the scapula, while the other end of the plate is electrically connected to spring-biased cable winding mechanisms. The two zones of the plate are separated and electrically insulated from each other by a predetermined gap which extends along the plate with a predetermined curvature or rectilinearly at a constant slope, and another slidable plate, having a contact member disposed therein, is similarly provided within another housing section with a harness cable at one end thereof, which cable extends laterally about the chest area of the patient, and is operatively, electrically connected to a spring-biased cable winding mechanism at the other end thereof through means of the contact member. The electricaly conductive plate and contact member of the second plate serve as a single-pole, double-throw switch and common contact member respectively, and the relative movement of both plates, as defined by the contact member and the zones of the electrically conductive plate, serve to open or close a signal emitting circuit so as to accurately indicate the assumption of a proper or improper postural position or condition by the patient, independent of the respiration of the patient. In another, electronic embodiment of the invention, in lieu of the sliding plates of the aforenoted embodiment, rotary potentiometers are utilized, the generated voltages of which serve to indicate the length or lengthening, or movement, of the cables secured thereto in a manner similar to the securing of the same to the sliding plates, and through means of a trim resistor, which serves a similar function as that of the sloped gap of the zoned plate, the voltages are differentially and then comparatively amplified and supplied to the signal emitting circuit.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 215 words
A posture training device to be worn by a person so as to improve the person's posture, comprising: first harness cable means disposed about the longitudinal axis of the torso of the person and having a length which is variable depending upon a change in the posture of said person and/or a change in the underlying curvature of the spinal column, as well as upon a change in the degree of respiration of said person; second harness cable means disposed transversely about the upper torso of said person and having a length which is variable depending upon a change in the degree of respiration of said person; signal emitting means for emitting a signal when said person assumes a poor postural condition or position so as to indicate to said person the assumption of said condition or position; electrical control means operatively connected to said first and second harness means for controlling an electrical circuit including said signal means; and means for correlating the changes in length of said first and second cable means such that said electrical control means will activate or deactivate said signal means only when the change in length in said first cable is due to a change in the posture and/or underlying curvature of the spinal column of said person.
Claim 2
Dependent Claim 215 words
A posture training device to be worn by a person so as to improve the person's posture, comprising: first harness cable means disposed about the longitudinal axis of the torso of the person and having a length which is variable depending upon a change in the posture of said person and/or a change in the underlying curvature of the spinal column, as well as upon a change in the degree of respiration of said person; second harness cable means disposed transversely about the upper torso of said person and having a length which is variable depending upon a change in the degree of respiration of said person; signal emitting means for emitting a signal when said person assumes a poor postural condition or position so as to indicate to said person the assumption of said condition or position; electrical control means operatively connected to said first and second harness means for controlling an electrical circuit including said signal means; and means for correlating the changes in length of said first and second cable means such that said electrical control means will activate or deactivate said signal means only when the change in length in said first cable is due to a change in the posture and/or underlying curvature of the spinal column of said person.
Claim 3
Dependent Claim 62 words
A posture training device as set forth in claim 1, wherein said electrical control means comprises: an electrically conductive plate, having two separate contact zones insulated from each other by a gap, operatively connected to said first harness cable; and a contact member operatively connected to said second harness cable; said plate and contact member establishing a single-pole, double throw switch assembly.
Claim 4
Dependent Claim 88 words
A posture training as set forth in claim 2, wherein: said plate is slidably disposed in the longitudinal direction upon a first section of a housing of said device; and said contact member is slidably disposed in the transverse direction upon a second section of said housing which is adapted to mate with said first section; whereby the sliding movements of said plate and contact member determine the relative disposition of said contact member relative to said contact zones of said plate so as to control said circuit.
Claim 5
Dependent Claim 44 words
A posture training device as set forth in claim 1, further comprising: spring biasing means operatively connected to said first and second cable means, whereby said lengths of said first and second cables are rendered variable against the biasing forces of said spring means.
