Description:

This invention relates to floatable stretchers and more particularly to such structures for use as litters to provide a ready means for transporting the injured or wounded on water in the same stretcher on which they are carried on land.

Heretofore, great loss of life has been experienced due to the difficulties of moving wounded and injured through or across bodies of water where boats could not be taken or were inaccessible. While some of these bodies of water could be traversed by stretcher bearers, it was impossible in many cases to handle wounded and injured stretcher cases, especially those seriously injured.

An object.of this invention is to provide a floatable stretcher structure which is compact and readily carried when disassembled, and which may be easily and quickly assembled and inflated in the field.

Another object of the invention is to provide 2o collapsible readily inflatable stretcher floats adapted to be quickly and safely assembled in position oh a regular stretcher so as to form a floatable stretcher which may be readily carried over land or floated over water. Further and more specific objects, features and advantages of the invention will more fully appear from the detailed description given below taken in connection with the accompanying drawings which form a part of this specification, and in which: Fig. 1 is a perspective view of an embodiment of the invention showing a floatable or buoyant stretcher ready for use; Fig. 2 is a plan view of one of the floats shown in Fig. 1 in inflated condition, with certain details of the ends omitted for the sake of clarity; Figs. 3 and 4 are respectively opposite end views of the structure shown in Fig. 2 and illustrate the structural end features; Fig. 5 is a view similar to Fig. 4, but showing the bladder flap open; Fig. 6 is a bottom view of the structure of Fig. 2; Figs. 7, 8 and 9 are respectively top and end views of a modified form of float utilizing two bladders instead of one as in Fig. 2; Fig. 10 is a somewhat enlarged view showing an alternative manner of attaching the floats to the ends of the stretcher shown in Fig. 1; Figs. 11, 12 and 13 are perspecive views show- 60 ing the manner in which the floats are packed when collapsed and the steps of removal and inflation; nhd Fig. 14 shows a somewhat modified form of stretcher with a float attached thereto. as Referring more particularly to Fig. 1: I desig nates in general a stretcher of conventional type provided with spaced apart longitudinally ex tending relatively rigid members, such as woodei side pieces 2-3 serving to support a canvas o the like member 4 serving as a carrying platforn secured to the side pieces, as by having oppo sitely disposed tubular margipal edges throug] which the side pieces 2-3 extend so as to ex pose handle ends of the side pieces. Legs 5and 7-8 are rigidly secured to the respective sid pieces 2-3 and in the present embodiment ar of stirrup shape. The pairs of legs 5-- ant 6-8 are provided with suitable jointed spreader (not shown) to maintain side pieces in spacec relation while permitting the stretcher to be col lapsed, in the manner well understood. Detach able collapsible pneumatic floats designated ii general as 9 and 10, are fastened in place ad jacent respectively opposite ends of the stretche in the manner to be more particularly describe following.

The floats 9 and 10 are each constructed an arranged as follows: A flexible casing II (Fig! 2-6) is provided by a tubular body member I (in the present embodiment formed by a seat 13) to the opposite ends of which are sewed sut stantially circular disc ends 14-15 so as to de fine a substantially cylindrical casing. The cas ing body is provided with axially spaced rein forced areas by means of patches 16-17 whic are secured thereto as by sewing. These patch( are preferably on the outside, but may be on th inside if desired, and extend around the casin to an extent to engage the stretcher body adje cent the side pieces 2-3 as well as the adjacer legs such as 5-8; thus preventing detriment! wear of the casing by chafing. One end of t1 casing is provided with a restricted slit openir (Fig. 5) I8 for insertion therethrough of a pnei matic bladder 19 (Fig. 2) whose inflation tut 20 extends through a suitable tongue and is ai cessible through said slit 18. A closure flap i is secured along one edge to the end 15 and provided with a snap fastener at its free end fb releasable attachment in closed position (Fig. 4 A canvas or the like flexible strap 22 has one ei strongly secured, as by stitching, to the end adjacent its diameter and its other end is pre erably provided with a buckle or the like fastel ing element 23 (Fig. 13) for ready engageme: with the free end of a cooperating similar stri 24 whose other end is similarly secured to tl casing end 15; thus providing a strap girth e tending longitudinally of said float for engag ment transversely of the stretcher, either through the stirrup legs, such as 5-8 (Fig. 1) or completely around the body (Figs. 10 and 14). Similar straps 26-26 have their corresponding ends firmly secured to the end 15, preferably extending transverse the straps 24, and their free ends are adapted to be fastened together, as by a buckle 21, to facilitate fastening the straps to the adjacent sides of the stretcher, such as to a leg such as 5 of the stretcher (Fig. 10) or to a leg such as 5' of the modified form of stretcher (Fig. 14), or to a handle (Fig. 1). The other casing end 14 is similarly provided with like straps 28-29 (Fig. 3) for securing the other end of the float to an opposite leg (Figs. 10 and 14) such as 7, or a stretcher handle (Fig. 1).

From the foregoing, it will be seen that the floats may be securely and quickly fastened In their respective positions on the stretcher body in such a manner as to prevent any possibility of accidental displacement thereon or therefrom, such as might result in serious detriment or fatality to the person being carried on the stretcher. It is further noted that the same float is adapted for use with different, types of stretchers, such for example as the U. S. Army litter (Figs. 1 and 10) or the British Uitter (Fig. 14).

In Figs. 7-9 inclusive, I have shown a modified form of float which in general is similar to the float previously described, except that in this latter embodiment the casing, which is designated in its entirety as II', is provided with a transversely extending bulkhead 30 serving to divide the same into two cells which respectively contain separate pneumatic bladders, such as 31-32. Each of the opposite casing ends is provided with a restricted slit opening and closure flap, for access to the filling tubes of the separate bladders, in all respects like that previously described in connection with the embodiment of Figs. 4-5.

Two floats in collapsed condition are normally carried in a bag, such as 33 (Fig. 11), preferably with a spare bladder, and the entire package )weighs only approximately seven pounds. A float may be readily removed (Fig. 12) and easily inflated (Fig. 13),. after which the inflation tube is closed, the closure flap shut and the float secured to the stretcher body as shnwn in wi 10I .fter the floats are secured in position (Fig. 1), patient may be readily transported over land n the usual manner until a body of water is eached, at which time the stretcher with the atient on it may be readily floated across the ody of water, and the transportation alternately verland and water is thus made possible. The neumatic floats also serve as efficient supporting ushions for the stretcher body.

Having thus described m' invention with paricularity, with reference to the preferred emodiment of the same, and having referred to ertain modifications thereof, it will be obvious o those skilled in the art, after understanding ay invention, that other changes and modificaions may be made therein without departing rom the spirit or scope of my invention and I im in the appended claims to cover such hanges and modifications as are within the cope of the invention.
