1 THERAPEUTIC DEVICE Filed Nov. 21, 1957 3 Sheets-Sheet 5 INVENTOR. NICOLA DELIA ATTORNEYS Unite 1 This invention relates in general to physical therapy devices, and relates more specifically'to a support device adapted to be selectively adjusted for positioning 'the limbs at the most favorable'heightfand angle with respect to a mattress surface for rest therapy. I

It is well known that mere rest in a sitting or prone position is often unsatisfactory to relieve the muscular tension and fatigue, or to rest the'he'art; Rest and relaxation with the lowerlimbs elevated is often recommended for general health tone, relaxation, and for the relief of blood pressure from exhausted limb muscles.

However, proper rest and the full value of elevating the limbs are not readily possible by the use of makeshift padding, or the practice of lying on the floor withthe limbs on a piece of furniture. The angle and height thus obtained are not proper, and quite often blood circulation is hampered. The results thus obtained are often worse than valueless; often the condition is aggravated.

Therefore, the principal object of this invention is to provide a leg support device having a means to cradle each leg at a selected height and angle above a mattress.

Another object of this invention is to provide a base support attachable to a mattress, with two leg supporting cradles angularly and elevationally mounted thereabove.

And another object of this invention is to provide a pivoted support of each leg cradle in the area of 'the ankle.

Other objects and a fuller understanding of the invention may be had by referring to the following description and claims, taken in conjunction withthe accompanying drawing, in which:

Figure 1 is a perspective view of the preferred embodiment of this invention witha bed and mattress indicated in phantom outline;

Figure 2 is a section taken along line 2-2 of Figure l to indicate the elevational adjustment characteristics'of one pivotal support; i

Figure 3 is a section taken along line 3--3 of Figure 1;

Figure 4 is a section taken along line 4--4 of Figure 1; and, i

Figure 5 is a side view of the apparatus, one position shown in full outline and another selected position of elevation shown in phantom outline.-

Reference is made to the figures of the drawings to illustrate what applicant believesto'be a practical and preferred embodiment of the invention; Others may likely change details but will find that the provisions of both elevation and angular tilting control are a novel and useful improvement in this type of therapeutic device. This control will provide unusual relief from fatigue and other types of lower limb ailments.

This apparatus embodies an attachment anchor portion which is indicated generally by the reference character 10. A superstructure 20 is held in an elevated and tilted position above the anchor portion in the novel manner of this invention, which will be more fully explained hereinafter.

States Patent Generally, the superstructure 20 is elevated by means of an elevator rack device 30 about an adjustable heigh ti pivot 35.

More specifically, the attachment anchor portion 10 embodies a U-shaped framework of strap members "11] and a liner 12. This U-shaped portion, as best illustrated in the Figures 1 and 5, is designed to fit upon a conventional bed mattress. Quite obviously, an exact fit between the mattress and the U-shaped member is not essential,

as it is desirable that this anchor portion 10 remain as In order to aid in the positioning and maintenance of stabil-. ity, a resilient member 13, preferably a spring, is provided to loop from the top wall portion of the U-shaped clip to the bottom wall portion thereof around the edge of the Furthermore, as best I stable in itsp'o'sition upon the mattress as practical.

mattress as illustrated in Figure 1. shown in Figure 2, a'threaded screw clamp 14 is carried by the top wall'of the U-shaped member in order to provide a tight clamp to' grip upon the top surface of'an associated mattress.

For further stability, a first and second footboard engagement member 15 and 16 is carried by the end wall of the U-shaped member. These footboard engagement members each have an arm 17 extending from the end wall in a direction to reach a footboard of a bed carrying the mattress to which the anchor member is engaged. Each arm 17 has a downwardly opening clip portion 18 toengage upon a bed footboard in order to provide stability for the anchor member.

The superstructure consists of two leg-cast shaped shields 21 with footed bottom ends 22 and interior pad-i ding to engage and support the human limbs.

It is quite important 'to the proper functioning and support of this invention to support the shields 21 properly upon the elevator rack device 30 and to be able to adjust the entire apparatus to a proper height. However, height I alone is not suflicient. Infinite angular adjustment within the range of the apparatus has been found to be exceedingly desirable. carried by the top wall of the attachment anchor portion 10 and is provided with a threaded wing nut 37. The, wing nut is thereby vertically adjustable on the stud to any vertical position within the range of the threads provided on the stud. A yoke 38 is provided with a central opening as best illustrated in Figure 2 to seat down over the stud 36 upon the wing nut 37 and therefore be sup- The opening in I ported at any selected elevator height. the yoke 38 is sufficiently large to allow a locking adjustment of this yoke and the supported superstructure shields 21.

In order to provide readily adjustable height support to the ankle area of the superstructure, the elevator rack directly under the ankle area of the shields 21. This location is quite essential to the proper support of the superstructure. Proper tilting adjustment cannot be obtained if this support is placed otherwise.

Inorder to pivotally connect the arm 31 under the super structure shields 21, ball and socket joint 32 is provided substantially as shown in Figure 4. A rack 33 is vertically adjustable by means of a manually operated pinion 34 as best suggested in Figure 3 of the drawings.

From the foregoing description it will be observed that the invention resides in an improved device for supporting the lower limbs in a selected position of elevation and angular relationship with respect to a bed mattress, and comprises generally an attachment anchor portion for attachment to a bed mattress for establishing a foundation support with respect to a bed and mattress, with a leg supporting superstructure held above the attachment anchor portion by means of a position control device To this end a threaded stud 36 is 3 essentially supporting the leg supporting superstructure upon the anchor portion.

Although the invention has been described inits preferred form with a certain degree of particularity it is understood that the present disclosure of the preferred form has been made only by Way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to Without departing from the spirit and the scope of the invention as hereinafter claimed.

I claim:
