The essential concept of this invention involves a pair of superimposed elements each mounting a hand grip and relatively shiftable longitudinal of each other against a normally-reacting pressure.

Basically, a physiotherapeutic exerciser embodying the foregoing concept comprises a pair of superimposed elements interconnected by one or more extension springs.

In the one adaptation, herein shown in FIGS. 1, 2, 3, 5 and 9, the elements are telescoping outer and

inner tubes

16 and 17 embracing an extension spring 18. In the other adaptation, herein shown in FIGS. 10, 11 and 12, the elements are in the form of

fiat bars

19 and 20 with a pair of exteriorly-arranged extension springs 21 and 22.

The detail structure of these two adaptations will be taken up in the above order.

In the one adaptation, the

telescoping tubes

16 and 17 have blocks 23 and 24 fixed in the opposite ends by suitable pairs of fasteners 25 and 26, respectively, which as herein shown also

anchor hand grips

27 and 28 to the opposite ends of the

respective tubes

16 and 17. The outer ends of the

tubes

16 and 17 are closed by the

caps

29 and 30. The lengths of these

tubes

16 and 17 are such that in their spring-retracted relationship the

hand grips

27 and 28 are spaced apart about 24 inches.

The spring 18 has its opposite ends anchored to the opposed inner ends of the blocks 23 and 2.4 by

pins

31 and 32 disposed radially of the

tubes

16 and 17 and extending through the conventional loop ends of the spring 18.

The inner tube 17 has a peripheral slot 33 extending nearly the full length thereof. A pin 34, fixed adjacent the outer end of the outer tube 16, rides in the slot 33 to keep the tubes from turning and to limit their outward extension.

The

hand grips

27 and 28 herein are shown as sections of tubing with one end portion of each flattened to provide arcuate-

shaped extension

36 and 37 whereby the hand grips are anchored to the respective tubes by the fasteners 25 and 26. Preferably a sleeve 38, of suitable flexible, friction material, embraces each of the

hand grips

27 and 28.

A modification of the adaptation shown in FIGS. 1, 2 and 3 is illustrated in FIGS. 59. This provides for positioning the exerciser over the shoulder of a patient to permit concentrating the exertion of one arm and hand. Such a modification involves an arcuate-sh-aped tubular part '39, as a substitute for the hand grip 27, and an accessory pad 41, both of which are slidably supported on the outer tube 16.

The part 39 is of arcuate form approximating that of the upper rear portion of the human shoulder. The upper end of the part 39 terminates in a split ring 42 with a wing-nut fastener 43 for clamping the part 39 at a desired point on the tube 16. Preferably, this arcuate part 39 mounts a cushion 41) of a contour such as shown in FIG. 6.

The accessory pad 41 is of rectangular contour and has an integrated ring 44 embracing the tube 16. The inner diameter of the ring 44 is enough larger than the outside diameter of the tube 16 so that a slight angling of the pad 41 to the axis of the tube 16 fixes the position of the pad 41 on the tube 16 so long as pressure is applied to maintain such angled disposition.

By use of such arcuate-shaped part 39 and the accessory pad 41 it is possible to position the exerciser over the shoulder of a patient somewhat as shown in FIG. 9. This so disposes the exerciser forward of the patients body as to permit the exercising of the one arm and. hand.

If and when desired a supplemental cushion 45, such as shown in FIG. 8, may be set over the rearward face of the accessory pad 41 to contact the front area of the patients shoulder. Such a cushion 45 here is shown with a pair of springs 46 (FIG. 8) for embracively positioning the cushion on the pad 41, as shown in FIG. 9.

The exerciser of the adaptation shown in FIGS. 1 through 9 may be used in two different ways. One of these J ways affords a yielding resistance to the repeated pulling of the two hands and arms of a patient outwardly away from each other and allowing the spring 18 to pull the hands and arms inwardly toward each other. The second way affords a yielding resistance to the pushing of one hand and arm outwardly from the corresponding shoulder and allowing retraction by the spring 18 to pull the hand and arm back toward the body.

For the way of using the one modification (FIGS. 1-4) it is only necessary for the patient to grip the

sleevecovered hand grips

27 and 28 and pull them outwardly from each other against the resistance of the spring 18. Upon releasing such outward pull the spring 18 will retract the

hand grips

27 and 28 inwardly to the full limit permitted by the collapsing of the spring 18. Such repeated pulling of the

hand grips

27 and 28 away from each other, with the intermittent releasing of such pull, will cause the desired exertion of the patients muscles to effect an improved condition for the patient.

For the way of using other modification (FIGS. -9) the padded arcuate part 39 is adjusted to the desired position on the tube 16 and secured in place by the wing nut 43. This padded part 39 then is placed against the back of the patients shoulder. The accessory 41 then is pulled rearwardly on the tube 16 to press against the front part of the patients shoulder. This positi-oning of the accessory 41 so angles the ring 44 to the tube 16 as to ensure the retained positioning of the accessory against the patients shoulder.

With the exerciser so positioned, the hand grip 28 is grasped by the patients one hand and the arm is extended forwardly against the action of the spring 18. Upon relaxing such outthrust of the arm the spring 18 will draw the hand grip 28 back toward the patients body. The repeated extending and retracting of the one arm will secure the result for that arm comparable to that resulting from the use of both hands and arms in repeated pulling the hand grips outwardly and releasing them, as above described.

In the other adaptation (FIGS. -15) the

bars

19 and 20, with integrated hand grips 47 and 48, are formed with longitudinal registering slots 49 through which extend pairs of spring-tensioned fasteners 51 for slidably retaining the bars superimposed on a supporting member 52 and biased outwardly by a pair of

springs

53 and 54. These springs serve to dispose the hand grips 47 and 48 away from each other a predetermined distance, approximately 24 inches. This makes it possible for a patient to acquire the exercising of the hands and arms by pushing the hand grips inwardly against the action of these

springs

53 and 54. In order to make possible this pushing inwardly of the hand grips 47 and 48, it is necessary for one of the bars, for example bar 20, to be formed with an opening 55 (FIGS. 11 and adjacent the junction of the hand grip 48 to allow the end of the other bar 19 to move outwardly beyond the junction of the hand grip 48 with the bar 20.

Sleeves 56 of molded friction material, are set over the hand grips 47 and 48 to afford a larger and more comfortable area for the contact of the hands during the use of the exerciser.

The fasteners 51, as best shown in FIG. 13, are the conventional-headed bolts 57 with wing-nuts 58. Between each of the nuts 58 and the member 52 is a spring 59. The adjustment of the two nuts 58 tension the springs 59, to supplement that of the

springs

53 and 54, so as to determine the degree of resistance to which the patient is to be subjected in the use of the exerciser of this adaptation.

Each of the springs 53 and S4 is encased in a pair of axially-opposed sections of

tubing

60 and 61. The opposite ends of each pair of tube sections are flattened to provide pads 62 apertured for the reception of screws 63 to anchor the tube sections, one each to the supporting member 52 and the other to the bar 19 or respectively.

Such tube sections

60 and 61 serve to protect the patient or parts of the clothing from being pinched or caught in the retracting springs 53 and 54, as might be the case if these springs were exposed through their entire length. The looped ends 64 of these

springs

53 and 54 are secured to the

respective bars

19 and 20 and to the supporting member 52 (FIG. 14).

The use of the exerciser of the adaptation of FIGS. 10-15 is as follows:

The fasteners 51 have the wing nuts 58 adjusted to effect tensioning of the springs 59 (FIG. 13) to an amount needed to provide the desired resistance to pressures the patient is expected to exert in pushing the hand grips 47 and 48 toward each other. The hand grips 47 and 48, being held apart by the retracted springs 53-54, the patient grips the sleeve-covered hand grips 47 and 48 and pushes them inwardly against the increasing resistance of the springs 53-54, to whatever amount of distance may appear practical for the patients needs. Upon relaxing the push of the hands inwardly the springs 53-54 will urge the hand grips 47 and 48 outwardly away from each other as shown in FIGS. 11-12. Such repeated pushing of the hand grips 47 and 48 inwardly and releasing them will cause the desired exertion of the patients muscles to effect an improved condition for the patient.
