llllllllil v Patented Jan. 19, 1943 UNITED sTATEs PATENT 'OFFICE RESUJENT INSERT-INSU COMBINATION Meyer Margolin, Elgin, Ill. Applltilln Febl'lil'y 3, 1941, Serial N0. 377,948 l 2 Claims. 36-3) Mv invention relates to a novel resilient shoe insole and more particularly my invention relates to a novel combination of insole, outsole 4and filler, which combination is adapted to provide increased foot comfort in that a softer and more resilient cushion is provided for the foot and increased breathing and ventilation effected.
One form of my invention which I shall describe more specically hereinafter is adapted to be employed in that type of shoe in which the insole is formed by splitting oil' a layer of leather from the outsole. 'I'he insole may be split from the outsole to provide a thin insole and a relatively thicker outsole, or the cleavage may be so effected as to provide a raised portion or island on the top or upper side of the outsole with a corresponding dished out concavity on the lower side of the insole. This raised portion or island may be so cut that the dished out concavity in the insole extends through the thickness of the insole and forms an opening in the center forepart thereof.
It is also within the purview of my invention to provide a metatarsal support element which is formed integrally with the filler and disposed in the proper position thereon.
'I'he advantages of the constructions as outlined above are manifold. First, I provide for a greatly increased exibility in4 the outsole-in sole combination and this flexibility is greatest in the center of the forepart of the insole whereA such flexibility is'desired. Second by my construction I provide for greatly increased resilience and softness of step for the shoe employing this.
construction and this resilience and softness is greatest at the ball portion vof the foot which is adapted to take the impact of the foot in walk? ing. The resilience tapers down from this ball portion to the peripheral portion'of the filler where the iillerapproaches'a feather edge thinness. Third, my construction provides for increased ventilation and breathing in these lshoes of the so-called one piece sole type. v
This application is a continuation in part oi' I my copendmg application serial No. 306,778, med
Nov. 30, 1939, for Novel insole and outersole combination.
It is the object of my invention to provide a nvel resilient comb ation of'outsoie, insole and i1 er.
It is a further object of my invention to provide a novel nller for a so-called one-piece sole.
These and further objects of my invention will become apparent from a consideration of the 65 whic 45 the shoe.
drawing and the specific description thereof I which here follows:
Figure 1 is a central longitudinal cross section of a form of my invention.
Figure 2 is a. topplan view of the form of my invention shown'in Figure 1.
Figure 3 is a transverse cross section along the line |3-I3 of Figurev 2. A f
Figure 4 is a central longitudinal cross section of another modified form of my invention.
Figure 5 is a central longitudinal cross section of another modified form of my invention.
Figure 6 is a top plan view of the modified form of my invention shown in Figure 5.
In Figure 1 I show a construction by means of which I provide increased shoe comfort. An outsole 60 and an insole 6| which has been split from the outsole so that an island or raised portion l2 ls provided in the center forepart of the outsole.
2o are joined after the upper M is lasted to the insole 6| in the usual manner. A resilient pad I! is secured to the insole BI by stitching Il and 61. I may provide on the resilient pad an integral '25 provided with grooves 10 and perforations 1|-,
30 ther provide perforations 18 in the insole Il by means of which perforations I achieve two new and unexpected results. First, the insole' is rendered more exible and secondly I provide increased breathing properties for the shoe in that thicknesses I may make adjustments in the shoe A .as desired. Thus. I may provide a snugger nt for the perforations in the resilient pad have great so nexibiiity imparted thereby. ,Y Figure 2 is a planA view of this resilient padinsole construction showing the relative position of the components of the assembly.
However, the resilient pad and the perforations therein together with the pex'i'orations in the insole directly below and matching In mure 4 I show an ummm 'utsoiein issecured tothe insole I ll after the upper 12 has been lasted to the insole |1I. superimposed upon the insole |1| is a rilient pad |13 having perforations |14. In the insole |1| are located periorations 15 which are positioned to constitute extension of periorations |14 and provide air pockets of increased volume. Perforations 15 also make for greater exibility and lightness ot the insole. In addition to the peri'orations |14 in the resilient pad, I may also provide grooves 11 and combination grooves and perforations 18. A molded metatarsal arch support 88 may also be provided on the resilient pad and the resilient pad may be secured to the insole |1| by any suitable means such as cement or stitching or the resilient pad |13 may be adapted to merely lie in frictional engagement with the insole |1| In Figure I show a resilient pad 82 which is adapted to act both as a means for increased ventilation, breathing and resilience and also as a size pad if desired in that by varying the thickness of the pad 82 various volumetric ad- Justments can be made within the shoe. The resilient pad 82 has periorations B3 which are adapted to coact with and lie superimposed over corresponding perforations 84 in the resilient insert 85 which is secured to the insole 88 by ,stitching 81. Certain periorations 88 in the rescribed. may be secured to the underlying insole or composite insole in any desired manner.
The combination oi' periorations in the resilient pad and the underlying -insole or insert are of particular importance because this construction enhances the ventilation and breathing which is in part resilient and by means oi soient pad sz are adapted to ne in communlcation with the combination perforations and grooves in the insert 85. In other instances I may provide combination perforations and grooves 92 in the resilient pad which are in communication with combination perforations and grooves 83 in the insert. The outsole 85 is secured to the insole 8B after the upper 88 has been lasted to the insole.
I may further provide in the resilient pad 82 a molded metatarsal arch support 81 having periorations 58 therein and in the insert 85 I may also provide a metatarsal arch support |58 hav- -perforations |01 in the insole 88 to provide air pockets oi increased volume for better ventilation and breathing of the shoe and also to increase the flexibility o! the insole.
It is to be understood that the resilient pad adapted to produce increased breathing, resil-` ience and foot comfort, above r dewhich increased volume is provided so that added breathing and coolness is obtained in the shoe in addition tothe enhanced ilexibility of the construction.
In the foregoing I have given a number of speciiic examples of my invention. Various modiiications and modined i'orms of the constructions here shown may be utilized to obtain the new and unexpected results set forth and will be obvioustothose skilledintheart. Iintendtherefore to be limited not by the specinc description here set forth but only by the claims hereto appended. Y
