(cl. 12s-94) l 3 Claims.

This invention relates to arm slings.

One object of the invention is to provide an arm sling of improved construction such that the sling can be easily mounted and comfortably worn.

Her-etofore slings for fractured or sprained arms have been haphazard affairs, improvised of such materials as happened to be available, and hence untidy and only partially efficient. Generally, the ends of the sling were tied together by a large knot at the back of the neck, causing an uncomfortable pressure, and disarrangement Such knots were inaccessible to the wearer and could be tied only by an attendant.

It is therefore an object of the invention to provide a sling which can be tied or adjusted by the wearer to suit his needs day by day, if

necessary, and further, to furnish such slings made in different colors to afford the wearer an opportunity of selecting a sling that shall conform or harmonize with his garments; and further, to provide a cushioning neck pad on the sling band.

Frequently an arm is most comfortable or heals best if held in a particular position at an angle to the horizontal. There has been no pro- 'vision for this in the slings heretofore used, and

in any case they tended to shift so that any special provisions made could not be relied upon.

It is therefore another object of the invention to provide a sling having improved means for convenient angular adjustment to suit the arm.

Oftentimes the sling tends to shift along the arm, necessitating readjustment. And of course the hand is exposed in cold weather.

I therefore provide a further improvement comprising a glove attached to the sling in such a manner that the glove is applied to the hand coincident with the placing of the arm in the sling, and the glove serving to prevent the sling from slipping from its desired position along .the arm.

Occasionally the arm may be subjected to impact which may cause considerable pain in a fractured arm. While the bandage may afford considerable protection, it may often be so thin as to be incapable of properly cushioning the arm.

Another object of the invention is therefore to furnish a sling having improved pressure distributing means such as spaced stiffener strips which shall not interfere with transverse flexibility and which shall permit the sling to be light and compact.

A further object of the invention is to provide a sling which shall be simple and convenient lin use, inexpensive in quantity production, adapted to be made in very few or only two sizes, to meet the needs of adults and children, and durable, reliable and eicient in use.

Other objects and advantages of the invention will become'apparent as the specification proceeds.

Withv the aforesaid objects in view, the invention consists in the novel combinations and-arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated in the annexed drawing, wherein like parts are designated by the same reference characters throughout the several views.

In the drawing:

The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined in one and the same structure, but, useful devices may be produced embodying less thanthe whole.

It will be obvious to those skilled in the art to which the invention appertains, that the same may be incorporated in several different constructions. The accompanying drawing, therefore, issubmitted merely as showing the preferred exemplication of the invention.

Referring in detail to the drawing, I0 denotes a sling embodying the invention. The same may be made of any suitable material such as cloth, rubber or other flexible or composition materials, which are preferably colored to harmonize with the clothing or uniform of thewearer. The sling may include an arm support or body section I l of any suitable shape and formed of one or more plies of material I2, I3. This body section is of suliicient size to embrace the arm and extend approximately from the elbow to the wrist. To one end of the body section Il is secured a band structure I4 which may be integral with the body section or suitably connected thereto. This band structure is of sufiicient length to engage around the back of the wearers neck and extend down to the other end of the body section at which it may be detachably or adjustably connected to thus avoid the formation of an uncomfortable knot or securement means at the neck of the wearer. structure I4 may also consist of a plurality of plies l5, I6 of material like those of the body section. Where it engages around the back of the neck, a cushioning means I1 may be provided which may comprise a sheet of material i8 enclosing any soft padding i9. A fastening means 20 at the remote end of the band i4 may include one or more series of spaced fastener elements such as tapes 2l detachably engageable with one or more companion fastener elements such as ring or loop elements 22 secured to the free end of the body section H. Thus adjustment to suit any desired angular position of the arm is easily obtained. Within the latter and extending transversely of the sling are a plurality of stiffener members 23 made of wood or composition material and serving to afford better` support to the arm and particularly to cushion and distribute accidental impacts.

The structure thus far described may be cheap- P ly made on a quantity production basis by securing or stitching together the different plies of fabric, as by an overseaming stitch 2li, after suitably positioning the tapes 2l, loops 22, and stiffeners 23 so that all of these are secured in one operation. If desired, the padding i8 may also be placed between the plies l5, i6. If the member I8 is employed it may be secured by the stitching 24, and then closed at its cross ends by conventional stitching at 25. Similarly stitching at 2S may form pockets for the stiffeners 23 to prevent them from shifting. Reenforcing tacking may be applied where necessary, as at the fastener elements.

Connected to the body section H is a glove 21 intended to protect the hand from cold and to position the body section of the sling against accidental shifting. The glove may be of any Well known type and only one part of the opening thereof is secured to the sling, permanently Aor detachably. The detachable arrangement is preferable to permit selection of gloves of different sizes, and therefore, I utilize any feasible connecting means, such as snap fasteners 28,

which leave the opening of the glove unobstructed so that the hand may be inserted into the glove coincident with the placing of the arm in the sling.

In use, the sling may be adjusted to the wearer by suiiicient take-up on the tapes 2! which are threaded through the loops 22 and secured by suitable knots as at 29. In so fastening the tapes 2|, adjustment may also be made for any desred angularity of the arm, and hence the take-up on the different tapes may be different. The wearer places his arm in the body section Il, whose reenforcements 23 serve to protect it by distributing any jarring impact. In mounting the sling, the hand is simultaneously inserted into the glove 27 to keep it warm in cold weather and to x the sling against shifting along the arm. The wearer may conveniently carry the weight of his arm in the sling because the band I4 is smooth and is cushioned by the neck pad I1.

The band In Fig. 5 is shown a modified sling having a body portion 3| from one end of which extends a band 32 having a cushioning neck pad 33 and terminating in a plurality of tapes 34. Companion tapes 35 are secured to the free end of the body portion for knotting with the respective tapes to obtain the adjustments for length and angularity. This sling 3U is in these respects like that at IIJ but omits certain features of the latter and hence is much more simple and cheap to manufacture.

In Fig. 6 is shown a sling 36 illustrating another modification of the invention. The same may include a body section 31 having at one end a band 33 having a neck pad 38a and carrying a buckle 39 which is adapted to be adjustably fixed therealong in any suitable manner. This buckle may suitably engage a companion fastener element 40 at the other end of the sling. Preferably the buckle 39 may have an eye portion 4l into which tongue 42 of the fastener 40 may be conveniently detachably engaged by the use of a single hand of the wearer. While vthe buckle 33 alfords adjustment for length, there may be adjusting means 43 for angularity. This may include a plurality of tapes adjustably knotted or secured as at 44, and converging from the body 3l to which they are secured to the band element 45 to which the fastener 40 is secured. Hence when once the tapes 43 have been adjusted they need not be disturbed in operating the fastener means 4l, 42. This sling 32 may be regarded as incorporating therein the other features of the sling l0, including the reenforcements 23, and the glove 2'! and it may consist of one or more plies, whose raw edges may be finished by an oVer-seaming stitch as in the sling l0.

It will be noted that the sling 36 may be used in the same manner and for the same purposes as the sling l0 except that it possesses the additional advantage that once its tapes have been adjusted for angularity they need not be disturbecl, and the wearer may put on and take off the sling with the single available hand, as by engagement and disengagement of the tongue 42 in the eye 4l of the adjusted buckle 39.

In Figs. 7 and 8 is shown a further modification including a sling 36a which may be exactly like sling 36 except that the buckle structure is different. Thus sling 35a may comprise a buckle having a loop portion 46, one side of which is passed through the loop 45, and the other side of which forms a pintle 46a for the ears 41 of a plate 48 carrying a serrated tooth portion 49. The part 48 is readily operated by hand to cause pivotal motion of the buckle so that the band 38 passed therethrough is gripped by the serrated tooth part 49. This buckle can be easily opened by merely tilting the plate 48 to the position shown. By the use of this buckle, the wearer may instantly adjust the length of the sling so as to support his arm at any desired elevation.

I claim:
