1 Claim.

The device forming the subject matter of this application is adapted to be used for carrying an invalid or injured person from the intermediate portion of a bar supported on the shoulders of two porters.

The invention aims to improve a novel construction in the back-rest strap and in the seat support, novel means being provided for assembling these instrumentalities with each other, releasably, and with the intermediate portion of the bar, releasably.

Within the scope of what is claimed, the structure described and shown may be changed, without departing from the spirit of the invention. This application is a substitute for application Ser. No. 546,241, filed July 24, 1944, which has become abandoned.

In the accompanying drawings:

Fig. 1 shows in perspective, an invalid carrier constructed in accordance with the invention;

Fig. 2 is an elevation wherein the back-rest appears in elevation;

Fig. 3 is an elevation wherein the back-rest is viewed edge-wise;

Figs. 4 and 5 are elevations showing a modification in the seat support.

In putting the invention into practice, there is provided a carrying bar I, which may be made of fir or any other light and strong material. Throughout the major portion of its length, the carrying bar i may be of rectangular cross section, but it is tapered in its end portions, to provide reduced handles 2. A U-bolt 3 is mounted in the carrying bar I, midway between the ends of the bar, and with the U-bolt, a releasable connector, for example, a snap hook d, is pivotally assembled.

The numeral 5 marks a ring, preferably made of metal, and detachably assembled with the connector or snap 4. The ring 5 serves two purposes. It serves to bring together at a single point, the constituent parts of a sling, to be described hereinafter: and it affords a centralized lifting point for the sling.

The sling, designated by the letter S is a composite structure. It includes a back rest, in the form of a flexible strap 6, preferably of uniform width from end to end, and made of cloth, if desired. For purposes of adjustment as to length, the back rest 6 is a two-strap structure, its constituent members having their inner ends adjust- 1 Number The seat support, forming part of the sling S, is marked by the numeral 9, and preferably is a flexible strap, which may be made of cloth. The seat support 9 preferably is somewhat wider in its intermediate portion than at its ends, for the comfort of the patient being carried, the seat support tapering towards its opposite ends, so that those ends may be formed into permanent loops l0, retaining, pivotally, snaps H, adapted to be engaged with the ring 5, forwardly of the snaps B on the back rest 6. The seat support 9 extends under the thighs or buttocks of the patient.

In the modification shown in Figs. 4 and 5 parts hereinbefore described have been designated by numerals already used, with the suffix a.

In this form of the invention, the seat support 9a is provided with buckles [2, which enable the seat support to be adjusted as to length.

The bolt constitutes an anchor. Through the instrumentality of the detachable connection afforded by the snap hook t, the invalid may be seated in a chair, the bar I being detached, and

An invalid carrier sling comprising a rigid car-- rier bar, handles at the ends of the carrier bar, a

. U-bolt secured to the carrier bar at a point intermediate the ends of the carrier bar, a snap hook secured to said U-bolt, a connecting ring secured to the snap hook, a strap-like seat support having snap hooks at its ends, the ends of the strap-like seat support being brought together and the snap hooks thereof snapped into said ring, and a flexible strap-like back rest, hooks at the ends of the back rest, the hooks of the back rest being brought together and secured to said ring, connecting the back rest to said ring.
