Abstract
A limb supporting device for reclining persons has a tri-segments pillow having a volumetrically predominate and apexial central-segment flanked by hingedly associated lower secondary-segments for uprightly stabilizing the limb supporting device upon a bed-like reclining surface. An elongate girth strap gives selectable contour and resiliency to the pillow central-segment according to the limb cradling needs of specific reclining persons.

Description
Background of the Invention
For persons reclining upon a sleeping bed or other substantially horizontal reclining surface, it is sometimes desireable to support the arm or leg body limb in a secure horizontal position but elevated slightly above the reclining surface. For example, victims of arm or leg trauma, the bedridden chronically subjected to bedsores, persons suffering from poor veinal circulation, as well as sufferers of various other maladies, are advised or instinctively desire to securely maintain the afflicted arm or leg some small distance above the bed-like reclining surface. Although conventional pillows as underlying props do provide a measure of relief, they lack sufficient lateral support for the afflicted arm or leg; moreover, an arbitrarily selected conventional pillow has a built-in constant resiliency which may not be suitable for the afflicted person's particular needs.
Object of the Invention
It is accordingly the general objective of the present invention to provide for reclining persons a limb supporting device that comfortably supports the afflicted limb reliably laterally securely and together with a selectable degree of resiliency that are not attainable with conventional pillows or with other prior art devices.
General Statement of the Invention
With the aforementioned general objective in view, and together with other ancillary and specific objectives which will become more apparent as this description proceeds, the limb supporting device concept of the present invention generally comprises a multi-segments resiliently-compressible pillow having an apexial and volumetrically predominate central-segment for cradling a reclining person's limb and also having secondary-segments respectively hingedly flanking lower portions of the central-segment and for stabilizing the limb supporting device upon a reclining surface, and an elongate girth strap attached to the pillow and adapted to constrictably controllably surround the central-segment to effect a selectable downwardly concave cradle-like contour and a selectable resiliency for the central-segment and to thereby provide a customizeable underlying support for the person's limb.

Detailed Description of the Drawing
The limb supporting device concept of the present invention generally comprises a multi-segments, resiliently-compressible (11) pillow (10) having an apexial and volumetrically predominate central-segment (15) having a longitudinal upper-edge (13) for supporting a reclining person's limb (e.g. leg L) above the horizontal reclining surface (RS) and also having secondary-segments (16A, 16B) hingedly (17A, 17B) flanking lower portions of the central-segment and collectively providing a horizontal longitudinal lower-edge (14) for stabilizing the device upon such reclining surface, and further comprises girth strap means (20) adapted to controllably constrictably surround the pillow central-segment (15) to thereby provide a cradle-like limb support of selectable resiliency as suggested by FIG. 4A.
A flexible shell 12, such as fabric material, surroundably encloses resiliently compressible filling material 11 into a pillow form 10 having generally parallel, horizontal and directionally longitudinal edges 13 and 14. In directions substantially perpendicular to pillow horizontal lower-edge 14, flexible shell 12 is horizontally and directionally transversly linearly joined together (e.g. by stitched lines 17A, 17B) to subdivide pillow 10 into three resiliently-compressible (11) segments, namely: an apexial and volumetrically predominate central-segment 15 having its lower portion flanked by hingedly associated (17A, 17B) secondary-segments 16A and 16B. Accordingly, the longitudinally extending upper-edge 13 of and having a finite-length is wholly defined by the apex or horizontal upper extremity of central-segment 15, and the longitudinally extending lower-edge 14 of pillow 10 is jointly defined by the collective lower extremities of pillow segments 15, 16A, and 16B. Moreover, pillow central-segment 15 has a pair of inclined and downwardly convergent side edges including:
(a) a left-edge 18A extending from the leftward terminus of pillow upper-edge 13 to the leftward hinged connection 17A, said left-edge 18A physically contacting pillow leftward secondary-segment 16A; and
(b) a right-edge 18B extending from the rightward terminus of pillow upper-edge 13 to the rightward hinged connection 17B, said right-edge 18B physically contacting pillow rightward secondary-segment 16B.
As clearly indicated in the drawing figures and in the foregoing text, the widthwise extending (i.e. FIG. 3) secondary-segments 16A and 16B serve to stably uprightly support the device (9) upon a reclining surface (RS).
Lambswool or other soft resiliently-compressible apron 19 might be stitched or otherwise topically applied at the apex of central-segment 15.
Elongate girth strap means (e.g. 20), for perpendicularly intersecting eges 13 and 14 and for controllably constrictably surrounding the central-segment (15), is attached to the device pillow portion. Herein, flexible fabric girth strap 20 has a regular narrow width between its terminal ends 22 and 28, and its first-end 22 is attached (as by stitching line 21) to a lower portion of pillow central-segment 15. As seen in FIG. 4A, girth strap 20 is significantly narrower than the finite-length of upper-edge 13; moreover, girth strap 20 is recessible within apron 19. Adjacent its terminal ends, girth strap 20 is provided with fastener means (e.g. VELCRO type fasteners 23 and 29) so that the girth strap means can be employed to controllably constrictably surround central-segment 15. Accordingly (and as alluded to in FIG. 4A), with regard to central-segment 15, the girth strap means is adapted to effect a selectable degree of upper-edge concavity (e.g. along 13) for stably cradling a horizontally extending body limb (e.g. leg L) and also a selectable degree of pillow resiliency beneath the cradled limb.
A pillow case provided of launderable or disposable material might be employed to removably encase the controllably constrictable and multi-compartments limb supporting device (e.g. 9). Moreover, the aforementioned topical apron (19) might be alternatively carried by such removable pillow case rather than by the pillow central-segment.
From the foregoing, the construction and operation of the limb supporting device concept will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
