turning to the drawings , fig1 a shows a splint 10 which is being used to provide lateral and vertical support to an injured index finger f . the splint 10 is formed from a base strip 11 which is bent into a desired curvature according to the bend required for proper healing of the finger f . extending upwardly from the far edge of strip 11 at a right angle are individual projections 12 - 1 through 12 - 6 . the finger f is cushioned on the strip 11 by a pad 13 . details of the splint 10 are shown in fig1 b . the strip 11 is bent to form a convex surface 11 - c . at one edge 11 - e are projections 12 - 1 through 12 - 6 which are general perpendicular to the surface 11 - c . each projection is separated at its base from an adjoining projection by a gap g - 1 . to permit the strip 11 to be bent into a desired configuration without interference between projections , each gap g - 1 extends into the surface 11 - c so that there is no material between adjoining projections at the surface 11 - c . because of the convex bend of the surface 11 - c , the projections diverge from the surface so that the gaps at the tips are wider than at the bases . as indicated by fig1 b , the pad 13 that is used to cushion the finger f is applied to the convex surface 11 - c . the pad 13 is desirably of foam or sponge rubber with an adhesive layer 13 - a that engages the convex surface 11 - c . a splint extension 20 in accordance with the invention is shown in fig2 . the extension 20 can easily be severed to form a strip 11 of desired size by the use of the grooves or notches 21 in the outer strip surface 21 - s . as can be seen in fig2 the projections 22 - 1 through 22 - n are separated from one another by a gap g which is of uniform width from one projection to the adjoining projection , when the strip 21 is in its unbent form . to facilitate the bending , no side metal is left between projections . thus gap g extends through the surface 21 - s of the strip 21 as well as between the adjoining projections . in some cases it may be desirable to provide further relief of material between adjoining projections by the use of an indentation at each such position in the strip 21 . as indicated , the strip 21 is gripped for a desired length and bent a number of times in the direction indicated by the arrows a and b to effect a separation of the excess material from the part that is desired . fig3 illustrates a splint 30 that has been proportioned to a desired length can be bent readily to assure a concave surface 31 - c for engagement with a member . in the case of fig3 the gap g between adjoining projections , e . g ., 12 - 2 and 12 - 3 , is wider at the bases than at the tips . in fact , depending upon the extent of bending there is no gap at the tips of the projections which overlap as shown in fig3 . fig4 shows a type of pad 13 that is used in conjunction with the strip to provide a desired cushioning effect . since it is advantageous for the pad 13 to adhere to the bent surface of the strips 11 and 31 , the pad includes a removable release sheet 13 - 3 which is peeled from the pad when the latter is to be positioned on the strip . it will be apparent that the length of the pad 13 depends upon the length of the strip , as well as upon the extent of the desired cushioning . in some situations it is desirable for the pad to extend beyond the edges of the strip to provide additional cushioning . in the embodiment of fig5 the splint 50 has elongated projections 52 - 1 through 52 - 6 which are bent over the finger f to provide additional support . in various tested embodiments of the invention , the splints 10 , 30 and 50 and the splint extension 20 were of sheet aluminum . it will be appreciated that other flexible metallic and non - metallic materials which are able to hold a prescribed contour as a result of bending may also be employed . moreover , while various aspects of the invention have been set forth by the drawings and specification , it is to be understood that the foregoing detailed description is for illustration only and that various changes in parts , as well as the substitution of equivalent constituents for those shown and described may be made without departing from the spirit and scope of the invention as set forth in the appended claims .
splinting of members , particularly injured or broken fingers , using a flexible strip with individual , perpendicular projections along one edge . the strip can be bent into a desired non - planar shape with the edge projections providing lateral support without disturbing the bendability of the strip .
