EMERGENCY STRETCHER CONTRIVANCE FOR USE on SKI TOURS Filed April 28, 1958 Theodo Ina/m 1 Patented June 11, 1940 PATENT OFFICE EMERGENCY STRETOHER ooNrmv ncE- i FOR USE ON SKI 'ro Rs Theodor Insam, Kitzbuhel, Germany,assignr to Degenhard Graf von Wurmbrand-Stuppach,

Vienna, Germany I Application April 28, 1938, Serial No. 204,86

Thisinvention relates to emergency stretchers, more particularly for usehlo n skiing expeditions,

of the' type in which the stretcher proper is b adapted to be mounted on a pair of skis serving as runners to form a sledge for the purpose of transporting injured persons over snow-covered country; The emergency stretcheraccording to my invention is composed of a specially designed knapsack of the type to be carried on the back and commonly known as a rucksack, two poles 0011-,

stituting longitudinal carrying members, and two transverse spreading members, and is adapted to bevclampedto a pair of skis by means of suitable bridgingmembers.

L Ehe rucksack, which serves in the extended condition for thesupporting of the injured personto be transported, consists of an elongated bag open at both ends, and of which the lower portionis adapted to berolled or wrapped around the. transverse members and bridging members after these two sets of members have been folded yup together to form a U-shaped unit. For this purpose the clamping devices provided at the ends of the bridging members are furnished with specially fitted protecting caps or pouches which are connected together by means of a strap or band adapted to bear against the small of the back when the emergency stretcher is being carried and thus to distribute the load. The emergency stretcher according to themvention is easily and rapidly folded up and unfolded. Its weight and bulk do not exceed greatly those of a normal rucksack, so that when car+ ried on a skiing tour, even over long distances, it entails a hardly noticeable additional load. A form of construction embodying the invention isshown, by way of example, in the accominvention.

panying drawing, in which:

the length of the contrivance according to the Fig.2 is a plan view of the same.

Referring to the drawing, the skis I serving as runners are coupled together for example by means of two U-shaped bridging members 2 of such cross-sectional shape as to resist bending, e. g.; L. or T-shapedcross-section, and made for, instance of iron or preferablyof lightmetal. At

able relatively to each other and provided with Fig. 1 is an elevation looking in the direction of In Austria March 12, 1938 p 2 Claims. (01. 280-12) gripping elements 4, I bent over at right angles, the plate 6 being for example longitudinally guided in keeping means 5 on the other plate 3. On one of the two plates, e, g., on the plate 6,

. the nut 8. screwing in of the screw l3 causes the gripping elements 4, l pertaining to the .two

plates 3, B to be drawn together and pressed An addiagainst the narrow sides of the skis. tional clamping action against the ski may then be exerted by tightening up the screw 9.

To the bridging members 2 there are clamped the likewise substantially U-shaped transverse strutmembers l4, for example as shown in Figs. 1 and 2 by means of detachable wing screws. IS. The limbs] l5 intended for the reception of the longitudinal carrying members are equipped with slots I! through which for example a second pair of skis It may be passed to serve as longitudinal members. It will be clear that narrow battens of any kind, ski sticks, or the like may alternatively be used for this purpose. At the ends of the limbs I5 there are further provided engaging apertures 19 for the attachment of straps or the like. Instead of wing screws "3 for connecting the members M and 2 together there may alternatively be used hinges, in which case the assembling of the stretcher for use merely necessitates hinging up of the transverse members [4 and may therefore be effected more rapidly than with the previously described form of construction.

Bayonet-joints may also if desired be provided for the same purpose.

The emergency stretcher sledge contrivance according to the invention also has the advantage of making it unnecessary to lift the'injured person off the stretcher and to transfer him into an ambulance vehicle, a procedure. which is often exceedingly painful and troublesome, since, after slackening the screws I6 or disengaging the hinges or bayonet-joints used in place of these screws, the stretcher proper, together with its load, may be lifted bodily 01? the improvised sledge frame consisting of the parts I and 2, If

. the members 2 and M are indissolubly connected together the clamping devices may be loosened and detached from the skis constituting the runners of the sledge, by slackening of the screws 9 and [3.

To form the hammock for the supporting of the injured person there is used a specially designed rucksack which consists of a sack or bag open at both ends and adapted to be unfolded or extended to the required length of the stretcher. After unrolling, the body of the rucksack is simply passed over the longitudinal carrying members of the stretcher, and then constitutes a slightly sagging resilient hammock 20, while the longitudinal carrying members l8 consisting for example of skis support the injured person effectively at the sides, so that no strapping down of the injured person on to the stretcher is necessary. The hammock 20 has cutaway portions 2! intermediate its ends.

For the purpose of packing up the emergency stretcher contrivance for transport the bridging members 2 and the transverse strut members I l are adapted to be folded up to form a U-shaped unit.

Finally, the emergency stretcher contrivance according to the invention may alsoybe used as a reclining chair, for which purpose skis and skisticks are used to form a frame and the unrolled rucksack to form a hammock.

I claim: 7 1. An emergency stretcher contrivance comsaid screw and firmly mounted on the said plate 6 there bears a pressing up screw l3 pertaining to the plate 3 and adapted to exert a pressing action in a direction parallel to the plane of the,

said plate.

2/111 an emergency stretcher, an inverted U- 5 shape-dbridging member, a pair of clamping plates carried by each end of said member, the plates of a pair being slidable relatively to one another and each having a bar gripper, oneof said plates being slotted, a nut member secured to the other of said plates and projecting through said slot, a clampingscrew passing through said nut for engaging a bar held by said grippers, and

a pressure screw carried by the slotted plate and 2a engaging the sideof said nut.
