Abstract

Abstract The apparatus is for testing the human body in a variety of positions, ranging from the vertical to the supine, while exercising on an ergometer; and can also be used for angular positioning of other biomedical devices. It includes a floor plate and a hinged plate upon which to fix the ergometer, a back rest and a head rest attached at right angles to said hinged plate and behind the seat of the ergometer, dual hydraulic cylinders for raising and lowering the hinged plate through 90* by means of a self contained hydraulic system, with valve means for control and positive stops on the apparatus to prevent over travel. Tests can be made with the subject positioned on the seat of the ergometer, through the various angles, with a substantially normal body attitude relative to said seat and ergometer.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 170 words
In a tilting table for an ergometer and other biomedical devices, designed to test the human body in a variety of positions from vertical to supine, of the character described, the combination comprising: a floor plate providing a base; a hinged plate pivotally connected to said floor plate and movable through a predetermined angle; positive stop means integral with said hinged plate limiting its angular travel; biomedical testing means mounted on said hinged plate operable by a test subject; cradling means for said test subject mounted on said hinged plate disposed to maintain substantially the position of the body of said subject while being tested, other than the angularity imparted by the test itself, while said subject operates said testing means; power means tilting said hinged plate through an angular course of travel such as to move the body attitude of the test subject from the vertical to the supine; and actuating means for said power means to selectively control the tilting movement of said hinged plate during a test.
Claim 2
Dependent Claim 170 words
In a tilting table for an ergometer and other biomedical devices, designed to test the human body in a variety of positions from vertical to supine, of the character described, the combination comprising: a floor plate providing a base; a hinged plate pivotally connected to said floor plate and movable through a predetermined angle; positive stop means integral with said hinged plate limiting its angular travel; biomedical testing means mounted on said hinged plate operable by a test subject; cradling means for said test subject mounted on said hinged plate disposed to maintain substantially the position of the body of said subject while being tested, other than the angularity imparted by the test itself, while said subject operates said testing means; power means tilting said hinged plate through an angular course of travel such as to move the body attitude of the test subject from the vertical to the supine; and actuating means for said power means to selectively control the tilting movement of said hinged plate during a test.
Claim 3
Dependent Claim 37 words
Apparatus of the character described in claim 1, wherein said hinged plate comprises an elongated stand hinged at one end to said floor plate and movable to describe an arc of 90* relative to said floor plate.
Claim 4
Dependent Claim 44 words
Apparatus of the character described in claim 1, wherein said stop means on said hinged plate comprises a vertically disposed flange at the pivotal end of said plate having an occluding edge relative to said floor plate restricting angular travel of said hinged plate.
Claim 5
Dependent Claim 63 words
Apparatus of the character described in claim 1, wherein said biomedical testing means comprises an ergometer with a stand and handlebars mounted on said hinged plate; pedals on said ergometer supporting the feet of a test subject; a seat connected to said stand supporting said subject with said handlebars while operating said ergometer; and read out instrumentation connected to said subject and ergometer.
Claim 6
Dependent Claim 134 words
Apparatus of the character described in claim 1, wherein said cradling means comprises: a saddle seat projecting between the thighs affixed to said hinged plate; a bar support for the hands integral therewith; a frame projecting substantially at right angles from the pivotal end of said hinged plate and rearwardly of said seat; a padded back rest of resilient material supported by said frame, yieldably contouring itself to the body of said test subject; a head rest affixed to said back rest in raised contour supporting the head and nesting the shoulders; said back and head rest cooperating to index a test subject on said seat such as to maintain said body position in substantially the same relative attitude thereto, through all degrees of angularity imparted to said hinged plate, from vertical to supine.
Claim 7
Dependent Claim 51 words
Apparatus of the character described in claim 1, wherein said power means comprises a hydraulic piston and cylinder system operably connected between said floor plate and hinged plate assembly such as to pivotally urge said hinged plate in reciprocal movement from flush position to one at right angles thereto when actuated.
Claim 8
Dependent Claim 50 words
Apparatus of the character described in claim 1, wherein said actuating means comprises a manually operated two-way switch mounted in juxtaposition to said cradling means such as to be operable by one hand of said test subject while maintaining the remainder of the body of said subject in test mode.
Claim 9
Dependent Claim 29 words
Apparatus of the character described in claim 1, wherein said actuating means comprises a remote control switch for said power means operable by one other than said test subject.
Claim 10
Dependent Claim 35 words
Apparatus of the character described in claim 1, wherein said actuating means comprises a remote control automatically programmed switch for said power means operable to program said tilting mechanism through a predetermined cycle of movement.
