7 Claims. 1
Our invention relates to exercising machines and included in the ob ects of our invention are:
First, to proxide an exercising machine in the form of a table and including means for restraining of the upper portion of the patients body while applying a predetermined tension to the feet of the patient. Second, to provide an exercising machine whereby the patient himself or an attendant may relax, extend, manipulate, side bend and help to establish the normal range of motion of the lower dorsal, lumbar and sacral areas of the spinal column for the purpose of helping the rehabilitation of the muscular and neurological structures of these areas and to help relieve spasms of these areas which may have been caused by disease, trauma or fatigue.
Third, to provide an exercising machine of this class wherein the degree of exercise afforded may be readily controlled or limited, if desired, so as to be maintained within the capabilities of the patient.
With the above and other objects in view as may appear hereinafter, reference is directed to the accompanying drawings in which:
Figure 1 is a top or plan view of our exercising machine.
Figure 2 is a fragmentary side view thereof.
Figure 3 is a transverse sectional view through 3-3 of Figure 1.
Figure 4 is a transverse sectional view through 4-4 of Figure 1.
Figure 5 is a transverse sectional view through 5-5 of Figure 1.
Figure 6 is a fragmentary, longitudinal sectional view through 3-5 of Figure 1.
Figure 7 is a sectional view through 1-! of Figure 6.
Our exercising machine includes table I having a padded surface and supported fromasubframe 2 of similar area by means ofvertical spacers 3. The sub-frame rests on :legs 4.
Near the head end of the table, there is provided, at each side, longitudinally extending guide bars 5 to which are adjustably secured, by fastening means 6, a pair of arm restraining members 1 adapted to engage under the arms of a patient to restrict longitudinal movement of the patient toward the foot end of the table.
The table I is provided with a rectangular aperture in which is set a back supporting and exercising panel 8. Thepanel 3 is mounted on aninner box frame 9, guided within an outer box frame I0, suitably secured to cross members forming a part of thesub-frame 2. The inner box frame is capable of vertical sliding movement. To accomplish this, a drive shaft II extends through the outer box frame and terminates at the sides of thesub-frame 2. A second or countershaft I2 is also supported in the outer box frame. This construction is best shown in Figures 3, Sand 7. The drive shaft and countershaft are provided with mating gears I3 and I4.
2 The gears are provided with lever arms I5, having rollers I6 which engage elevator bars I I, secured in theinner box frame 9. Rotation of the drive shaft I I causes the lever arms I5 to raise the inner box frame. The inner box frame and panel lower by gravity.
The extremities of the drive shaft II are provided with upwardly directed handle levers I8, terminating in handles I9 directed outwardly from the table. The handles are so located that they may be grasped by a patient lying on the table.
The table I is also provided with a circular opening in which is set apelvis exercising panel 20, capable of pivoting movement. The pelvis exercisingpanel 2|] is mounted on anunder frame 2| having a central pivot pin 22 and supported on a suitableball bearing structure 23.Struts 24 are secured to the under frame 2I and extended from the foot end from the table I between the table and itssub-frame 2. The extremities of the struts are connected by a cross bar. In addition, the struts are provided with aroller carriage 26 which rides on the end member of the sub-frame, this member having a radius of curvature centered at thepelvis exercising panel 20. The projecting extremities of thestruts 24 are provided with vertically disposedguide brackets 21 which form tracks on which slide a series ofweights 28. Each set of weights is connected by a cable 29 which passes over a pulley 30 at the upper extremity of thecorresponding guide bracket 21 and is attached to a boot 3 I, adapted to receive a foot of a patient.
Secured under the table I, are a pair of bar crank levers 32, having arms withrollers 33 at their extremities, engageable with thestructs 24. Thebar cranks 32 are provided withfulcrum pivots 34, separated by a cross bar forming a part of thesub-frame 2. The remaining arm of each bar crank lever is joined to a connectingrod 35 which, in turn, is secured to alever arm 33, having asleeve 31 adapted to journal an end of the drive shaft I I. Each sleeve, in turn, is journaled in a bearing 38, secured to thesub-frame 2. Eachsleeve 37 is provided with ahandle arm 33 which extends upwardly adjacent a corresponding handle arm I8. The upper extremities of thehandle arms 39 are provided with inturned handles 4|].
Operation of our exercising machine is as follows: The patient lies on the table in a supine position. Theboots 3| are fastened over the feet of the patient. The patient is so positioned that the pelvic region is centered on thepanel 26. The arm restraining members 6 are'positioned to engage under the arms of the patient so as to restrain the patient against movement towards the foot of the table. Theweights 23 are arranged in units so that one or more weights may be applied to provide the desired degree of tension on the boots. By reason of the fact that thepulleys 33 are above the level of the table, the patients feet are raised slightly. The patient or attendant can then operate the handles 46 to pivot the exercise panel and to move the extremities of the struts, including the boots and weight members, from side to side. Also the patient or attendant can operate the handles I9 to raise and lower the back position and exercising panel 8.
Thus, by means of handles [9 or 40, the patient and attendant may relax, extend, manipulate, side bend and help to establish the normal range of motion of the lower dorsal, lumbar and sacral areas of the spinal column to help rehabilitate the muscular and neurological structures of these areas, and to release spasms of the above mentioned areas which may have been caused by disease, trauma or fatigue.
Having fully described our invention, it is to be understood that we do not wish to be limited to the details herein set forth, but our invention is of the full scope of the appended claims.
