SHIELDS 'FOR CORNS AND THE LIKE Filed Nov. 8, 1957 INVENTOR, lmmgyis/no nfiorr;

Y 0 in United St The object of the invention is to provide improvements in shields for corns, growths of various sort and other such diseased conditions, hereinafter referred to by the and compressible protective shield of this general type,

generic term corns, particularly but not exclusively limited to those occurring upon the human toe or finger, this application being a continuation-in-part of applications bearing the respective Serial Nos. 464,419, 521,120 and 610,970, all now abandoned.

Another object is to provide a shield of this general class, that can be operatively attached to a toe or finger without the use of an adhesive of any sort, and which can be both attached to and detached from such digit without destruction or substantially permanent deformation of the shields as originally formed, and which shield can therefore be used and reused two or more times, especially as when no medicament is received and present, and the shield is required to and does function merely as a protective device.

A further object is to provide in one form a shield that comprises an elongated disk, tab, or strip, of an ultra-soft, yielding and preferably elastic material such as, but by no means limited to, foam latex, cotton and similar materials in the fiber category, each of which is capable of protecting a diseased or inflamed area without abrading or otherwise injuring the same in the slightest degree, said disk or the like being provided in each of its opposite end areas with a preferably transversely extending slit or abbreviated partial severance, from which little or preferably no material is removed, and so related as to provide between them a sufiicient area or space capable of completely covering and protecting the corn. Whenthe improved shield is formed of foam latex or the like, it may be considered advantageous to incorporate in the mass a suitable soft reinforcing fiber of high tensile strength and resistant to deterioration, such as can result from extreme atmospheric and temperature conditions.

A still further object is to provide a shield of this character in which the slits or partial severances are of suflicient distance from the opposite ends of the disk, that such end portions naturally project in opposite directions and in any case lie flat and closely against the opposite and usually the under surface of the toe or other digit, after the central portion of the disk has been bent or rounded into such shape as is representedby an inverted U, so that its central portion overlies the affected area of the digit, and the slits or partial severances being distended sufficiently for spaced portions of a digit to pass through them.

And a still further object resulting from the employment of slits, as distinguished from apertures from which suflicient material has heretofore been actually removed to pass spaced portion of the toe or other digit, is to provide a product which has been proved to hold its predetermined initial shape during ordinary handling, storage and transport, and which when removed after a given period of use will tend to and in fact does almost invariably resume its initial shape, as originally produced preferably by reciprocatory dies or rolls, and thereby Which is characterized substantially centrally by two or more intersecting slits or partial severances providing an X or star arrangement of highly flexible cars, which ears when positioned over a corn of similar enlargement are readily adapted to flex outwardly, or transversely of the general plane of the adjacent portions of the shield, in order to thereby accommodate themselves in angular position and compressed thickness to the depth, length, width and possibly other details of the shape and size of the enlargement, the presence and characteristics of such ears being independent of the position and method of attachment of the shield to the digit, though their combined presence in a shield contribute towards a degree of efficiency heretofore unattained, as evidenced by long and widely proved clinical research and practical usage.

With the objects thus briefly stated, the invention comprises further details of construction, which are hereinafter brought out in the following description, when read in conjunction withthe accompanying drawings, in which Fig. l.is a plan view of a preferred form of the invention, showing one of the initially and normally fully closed terminal arcuate slits slightly distended, as its adjacent free end portion is pulled longitudinally away from its central portion, as afirst step in passing a toe or other digit through it; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is a plan view of a slightly modified form in which, instead of fully closed slits, narrow crescent-shaped transverse end apertures are provided, which are to be individually distended further when necessary to insert spaced portions of the toe or finger through them; Fig. 4 is a section on the line 44 of Fig. 3; Fig. 5 is a top plan view of an improved disk after it has been extended and rounded into a substantially inverted U-shape for attachment to a toe as shown; and Fig. 6 is a side elevation of the same, in which the corner of the central portion is provided with an aperture, the corresponding central portions of the preferred forms being provided ,with intersecting slits, that provide deflectable angular tongues, that can yield transversely of their common plane so as'to better conform to the surface of the corn or other enlargement beneath it and thereby eliminate whatever pressure might otherwise be applied to such surface. At this point it should be noted that it is difficult to correctly illustrate a product of this nature, which by reason of its elasticity, compressibility and general softness does not have its exact initial thickness preserved at all times, as unequal and unanticipated pressures and tensions may be applied during the ordinary application, use and wearing of the product.

Referring to Figs. 1 and 2, a disk of any desired shape is cut from a sheet or layer of a very soft material such as but not limited to foam latex, cotton, or the like, said disk being reinforced if desired and embodying any suitable outline, but here shown as having a central body portion 1, having rounded end edges 2, which may be and preferably are connected by generally parallel or but slightly convexly curved side edges 3, said end and side edges being also preferably cut in scalloped or sawtooth form, so as to permit their relatively freely projecting portions 4 to spread laterally, as they are compressed by the pressures to which they are normally subjected, when worn and covered by either or both a stocking and a shoe or slipper.

Each of the end portions 5 of said disk is provided with a generally transversely extending arcuate slit 6, of preferably crescent shape, and from which preferably no material is removed as in the case of an ordinary aperture, and which maybe easily distended or widenedto provide an actual opening. Such a slit in its initial form and closed condition is shown as positioned in the right hand end of said disk, while the corresponding slit 7 in the left hand area is shown after having been slightly opened by the manual separation of the adjacent end portion from the central body portion 1 of said disk, and which slightly opened condition may be temporarily expanded to form a generally crescent-shaped or even a circular aperture for the reception of a toe or finger, said adjacent end portion automatically returning when released to its initially closed normal position, as a result of the elasticity of the material of which it is made.

It should be especially noted that the marginal end portions 5 are of such transverse extent longitudinally of the disk as a whole, that when deflected so as to be positioned upon the opposite and usually lower or under surface of a toe they lie flat and closely against said surface (see Fig. 6) as distinguished from otherwise tending to stand upon their edges and thereby cause more unnatural localized pressure than is desirable, and which is substantially entirely avoidable when lying fiat and at the same time is formed from ultrasoft, and yielding material such as above mentioned. This preferred form may also, if desired, be provided with a pair of intersecting, centrally positioned, crossed slits 9, that together provide outwardly yieldable tongues 10, that adequately protect but readily yield so as to conform to the surface of a corn of the like and relieve possible pressure thereon, while said tongues may initially terminate centrally in a small, central aperture 12, that serves both as an aid towards breathing by the affected area and also eliminates the otherwise sharply angular terminals of said tongues, which might tend to fray if the radially inner portions of such tongues were characterized by angles of 90 degrees or less.

Referring to Figs. 3 to 6, parts similar to those shown in Figs. 1 and 2 are likewise similarly numbered. However, in this form the product is provided with a pair of narrow crescent-shaped aperturesll in lieu of the transverse arcuate slits 6 above described, while the end portions 5 are of substantially greater width than was previously considered advisable, as such wider end portions easily lie flat against the opposite side of the toe, as shown in Fig. 6 and hereinbefore described, and regardless of which of the ultra-soft substances is used, and whether reinforced as by ramie or similar fiber, the compressed flat end portions are so completely compressible as to be practically undetectable.

In Fig. 6 the body portion is shown as being provided with a fully cutout central aperture 13 for those who prefer it in lieu of the intersecting slits 9 ofthe forms first described.

Having thus described my invention, what I claim and desire to protect by Letters Patent of the United States ls:
