Primary Examiner-Casmir A. Nunberg [57] ABSTRACT An apparatus for suspending and supporting a cover [111 3,798,685 Mar. 26, 1974 over a medical stretcher. The apparatus comprises an assembly which includes: a horizontal cross member which has two ends; a first vertical leg which has two ends, with one end pivotally, and releasably, connected to one end of the horizontal bar, and with the other end of the first vertical leg 'releasably engaged to one of the two parallel poles of the stretcher; a second vertical leg which has two ends, with one end pivotally, and releasably, connected to the other end of the horizontal bar, and with the other end of the second vertical leg releasably engaged to the other of the two parallel poles of the stretcher. The assembly, when used with the stretcher, forms an inverted U in a transverse position over the stretcher, and thereby suspends and supports a cover over the stretcher and the patient thereon. A plurality of these assemblies, when used with suitable spaces, such as connecting rods, may be used to form an integrated unit of the desired length to support and suspend a cover in the shape of an inhalation therapy-type canopy over a stretcher and over a patient.

12 Claims, 4 Drawing Figures PATENTEU IIAR 26 I974 SHEET 1 [IF 2 COVER SUPPORT ASSEMBLY BACKGROUND OF *THE INVENTION This invention relates to a support for a cover and, more particularly, to a cover support assembly, and to a cover support assembly system, adapted in preferred embodiments for use with a conventional medical stretcher.

As a preliminary matter, it is to be noted and to be remembered that the word cover, as used heretofore and hereinafter, is intended to be broadly used and to mean anything which is, or can be, used to cover the occupier of a reclining apparatus, such as a stretcher or litter, a cot, or a bed. A cover may constitute or include, by way of illustration, linens (such as bed sheets), blankets, and even, for example, a cover in the shape of an inhalation therapy-type canopy.

Cover supports, and cover support assemblies, are not per se novel. The state-of-the-art has progressed slowly, with some notable advancements being made during wars and other armed conflicts with regard to adaptations for specialized uses. Known cover supports, and cover support assemblies, in specific embodiments for a particular adaptation have, generally speaking, served the very specialized purpose intended.

However, it is fair and accurate to say that there is no cover support, or cover support assembly, which is multi-purpose. The prior art, and our analysis and experience, clearly establish that the cover support, or cover support assembly, which is urgently needed and which is not presently available, should be multipurpose, as previsouly stated, and in addition should be articulated, compact, collapsible (i.e., foldable) and expandable (i.e., unfoldable), lightweight, portable, and, of course, inexpensive to manufacture, simple, and reliable.

We have invented such a cover support, or such a cover support assembly, and in addition a cover support assembly system. Thereby, we have achieved a goal long sought in the art; we have fulfilled a current urgent need; and, most importantly, we have, as a result, significantly. advanced the state-of-the-art.

As a matter of convenience, and in the interest of brevity, our invention, and the fundamental features thereof, will be shown and described with regard to preferred embodiments, as adapted for use with a medical stretcher. The need for such adaptions of our invention in the medical art is particularly urgent. It is emphasized, however, that such adaptations are solely by way of illustration, and are not-in any manner by reason of any limitation. As a related matter, it is to be remembered that the conventional medical stretcher comprises a bed" portion, usually made of canvas and referred to as the canvas, and a supporting frame which includes two identical poles, also sometimes referred to as bars or shafts," in parallel spaced relationship to each other. As is well known, medical stretchers, or stretchers" as they are more often referred to, are usually used to carry or to transport a sick, injured, or otherwise disabled person.

In addition to what has already been said hereinabove with regard to the cover support art, it is important to known, and to state herein, that it is usual, and most often necessary, to cover the sick, injured, or otherwise disabled person who is being carried or transported on a medical stretcher. The covering of the patient may be to protect, to provide warmth, or at least to provide privacy to the patient. Unfortunately, many patients, such as those having sever burns, amputations, and wounds, frequently cannot tolerate the weight, the tension, or the friction caused by the cover, even as light as a bed sheet, when the cover is in physical contact with the afflicted portions of the patients body,

Therefore, there has been, and there still is, a continuing, genuine and critical need for a cover support for a medical stretcher, wherein the cover used may be suspended and supported over the patients body, i.e., the cover does not physically touch the afflicted portions of the patientss body. In addition, there is a pressing need for a support for a canopy-type cover which must be used with a medical stretcher to provide necessary inhalation therapy, such as oxygen and humidification, to a patient on the medical stretcher.

SUMMARY OF THE INVENTION This invention pertains to a cover support assembly, and to a cover support assembly system, for use with a reclining apparatus, such as a medical stretcher.

Therefore, the principal object of this invention is to provide an assembly and an assembly system which will support and suspend different types of covers, such as linen bed sheet or a canopy, over the occupier of different types-of reclining apparatus, such as a stretcher or a litter, a cot, a bed, or the like, and therefore is multipurpose.

Other equally important objects are that the cover support assembly and the cover support assembly be articulated, compact, collapsible (i.e., foldable) and expandable (i.e., unfoldable), lightweight, portable, and, of course, be inexpensive to manu-facture, simple, and reliable.

These objects, and related objects, of this invention will become readily apparent after a consideration of the description of our invention and reference to the drawings. I

With reference to FIG. 3, therein is shown, in a prospective view, another preferred embodiment 100 of our invention in use with a conventional medical stretcher (also shown in FIG. 1) and in use with an inhalation therapy canopy-type cover 200. Our preferred embodiment 100 is a cover support assembly system for use with, and for releasable engagement with, a medical stretcher (10, FIGS. 1 and 3) such as previously described herein and which includes a bed portion 11. (FIGS. 1 and 3) and a supporting frame which, in turn, includes two identical carrying side poles, a first pole 12 (FIGS. 1 and 3) and a second pole 13 (FIG. 1 and 3), which are in parallel spaced relationship and which are, essentially, cylindrical in shape. Our preferred embodiment 100 is structured and configurated for use ideally with a canopy-type cover, such as inhalation therapy canopy 200, and it l00suspends and supports cover 200 over the medical stretcher 10 (FIGS. 1 and 3), and over a patient (not shown) on the stretcher, in a transverse position over the stretcher and over the patient thereon.

Still with reference to FIG. 3, our cover support assembly system 100 includes: a plurality of identical cover support assemblies such as 30 (FIGS. 1, 2 and 3) and 130; and, means for releasably connecting the plurality of identical cover support assemblies, such as 30 and 130, in parallel spaced relationship, whereby an integrated (or combined or connected) unit of the desired length is formed, substantially in the shape of an inverted and elongated U, or an inverted U shaped tunnel-like frame, in a transverse position over the medical stretcher 10 (FIGS. 1 and 3) and, of course, over the patient (not shown) on the stretcher; and the cover, such as canopy-type 200, is suspended and is supported over the stretcher (and over the patient).

Again with reference to FIG. 3, each of the identical cover support assemblies, such as 30 (FIGS. 1, 2 and 3) and 130, comprises the components already shown and described with regard to the structure of our preferred embodiment 30 (FIGS. 1 and 2). Therefore, no useful purpose would be served by reiterating those components and their interconnection and their interaction. Accordingly, no such description is given here, and the reader is respectfully referred back to our description of preferred embodiment 30. However, it is believed appropriate, for illustrative purposes to state that clasp 161 is identical to clasp 61 (FIGS. 1 and 3), that vertical leg 141 is identical to vertical leg 41 (FIGS. 1 and 3), that horizontal cross member 131 is identical to horizontal cross member 31 (FIGS. 1 and 3), that vertical leg 151 is identical to vertical leg 51 (FIGS. 1 and 3), and that clasp 162 is identical to clasp 62 (FIGS. 1 and 3).

Further with reference to FIG. 3, the said means for releasably connecting a plurality of said identical cover support assemblies, such as 30 and 130, in parallel spaced relationship, may include a plurality of spacers, such as 310 and 320, each of which is, as a matter of convenience and preference, but need not be, a (or in the form of a) connecting rod, as shown in FIG. 3. The releasable connecting rods 310 and 320 are, of course, of equal length.

With reference to FIG. 4, therein is shown, a side elevation view of a conventional medical stretcher 10, such as already shown in and described with reference to FIGS. 1 and 3, with a patient 20 reclining thereon. Also shown is our second preferred embodiment 100 of our invention, previously shown in and described with reference to FIG. 3, which in use with the stretcher and which is suspending and supporting a cover (i.e., the linen bed sheet previously shown in FIG. 1) over the patient 20 in a transverse position over the stretcher l0 and over the patient 20 on the stretcher.

FIG. 4 shows another adaptation of our second preferred embodiment 100. A repetition of a description of embodiment is not believed necessary, and the use of preferred embodiment 100 is as explained above and is an illustrated.

MODE OF OPERATION OF THE PREFERRED EMBODIMENTS The mode of operation of each of our preferred embodiments 30 (FIGS. 1 and 2) and 100 (FIGS. 3 and 4), may be easily and rapidly ascertained by a person of ordinary skill in the art from the hereinabove descriptions of the preferred embodiments, coupled with an examination of our FlGS. 1-4, herein. A detailed description of said operation is, therefore, not believed necessary. It is sufficient to state that the particular embodiment is snapped onto the poles of the stretcher for use; that the cover is then drapped over and suspended on the horizontal cross member(s); that, by that step, the cover supports the cover over the stretcher and the patient thereon. The procedure is reversed to discontinue the use of the particular embodiment, including unsnapping the clasps from their respective stretcher poles and, if desired, folding the particular embodiment.

it is clearly evident that our invention, and the two preferred embodiments shown and described herein, attains all of the objects desired, as set forth in the sum mary of the invention. Therefore, we do not believe that it is necessary again to set forth those objects, and other objects related thereto, and to show how each and every object, and others, specifically are achieved by our invention..However, we believe it important to state that, in addition to the basic structural novelty of our invention, and of the two preferred embodiments shown and described herein, our invention also attains new, useful, and unobvious results. For example, our invention is multi-purpose, both as to type of cover usable therewith and as to type of reclining apparatus with which it may be used. This multi-purpose feature is clearly unlike any prior art device or apparatus. While there have been shown and described the fundamental features of our invention, as applied to two preferred embodiments and as adapted for a particular use and purpose, it is to be understood that various substitutions, omissions, additions, and adaptations can be made by those of ordinary skill in the art, without departing from the spirit of our invention. For example: the clasps, such as 61 and 62, may be pivotally, and releasably, mounted to their respective vertical legs, such as 41 and 51; and, the vertical legs, such as 41 and 51, may be hingedly, rather than pivotally, connected to horizontal cross member 31. Additionally, our invention can be used, or can be adapted for use, with any type of reclining apparatus, other than a medical stretcher, such as a bed.
