which extend through openings in the insole and in the underlying layer, which downwardly depending lugs may protrude beyond the under'- lying layer so as to rest upon the outersole.
In shoe making, it is extremely desirable that the insole of the shoe be extremely flexible and elements in the flexible and breathing insole combination of my invention.
Referring now more specifically to'the drawing, in Figure 1 I lshow a layer I0 which is molded from `rubber or cellular rubber such as sponge or closed cell rubber. Downwardly depending from lthe underside of the layer I are it is further desirable that ventilation and breath'- ing be effected within the shoe construction so that foot comfort is enhanced.
I have now provided a novel construction by means of which the desirable insole flexibility and the desirable forced breathing effects may be obtained by a combination of resilient layers and insole. l
It is the object of my invention to provide a novel combination comprising an insole which has been rendered more flexible by openings died therethrough and aoverlying layer formed, for example, of resilient rubber material, which overlying layer carries downwardly depending lugs', which extend through the openings in the insole and throughcorresponding openings in an underlying resilient layer formed, for example, of rubber to form a laminated frictionally adhering construction characterized by flexibility and forcedA breathing properties. I
It is a, further object of my invention to provide 'a novel combination of insole, overlying layer and underlying layer, with downwardly depending lugs from the overlying layer which extend through and beyond the underlying resilient layer so that such lugs rest upon the outersole of the shoe to increasethe resilience of the construction and to obtain enhanced forced breathing effects. A
It is a further object of my invention to provide metatarsal support by means of an integrally formed metatarsal support resiliently'. maintained in the above construction.
These and further objects vof my invention will be apparent from a consideration of the drawing taken in connection with the specific description which here follows.`
Figure 1 is a plan view of the three component elements of my invention.
YFigure 2 is a cross section taken along the line 2;-2 off`Figurel,.showing the assembly of these lugs II as shown in the cut away portion of the layer I0,- and shown in dotted lines'at I2, I3, I and I5.' 'I'hese downwardly depending lugs may be variously spaced and located in accordance with the frictional adhesion of the parts or the breathing effects desired. Mounted or integrally formed on the layer I0 is a metatarsal support I6 through which extend perforations I1. Perforations I8 in the main body of the layer I0 afford' transmission of the air through the compositestructure and facilitate the transmission of the forced breathing effects of the construction'to the interior of the shoe. On the bottom of the layer III, I provide grooves 20, and 2| which may be open ended or may have terminating walls 22; 23, 25 and 2l, as shown, which terminating l walls enhance the breathing effects. Located in the groove 2J are perforations .21 which transmit air directly from the groove 2| to the interior of the shoe.
A second element of my combination is the insole 30 which has openings 3| for the reception of the downwardly depending lugs II, and I may further pi'vide various other perforations 32 and Y 33 whichl facilitate the transmission of air from the`construction to the shoe interior. These p erforations further increase the flexibilityK of the insole which'is a desirable feature.
' A third component element of my construction comprises an underlying layer In of resilient material'which'carries on its upper surface grooves 4I, 42, etc., and through which extend perforations 43, M, for the transmission of air. The action of the grooves 4I and 42 is similar to that of the grooves 20 and 2l above, namely the grooves increase the iie'xibility of the layers and also cause a, forced breathing upon flexing of the construction in normal shoe use. Groove 42 may contain perforations- 45 which directly transmit air from the-grooves to the undersurface of the layer to provide circulation thereof.
ditional breathing functions by the air spaces i and 52. It will be noted from this drawing that the lugs I I extend through and beyond the lower layer 40 and rest upon the outsole -53 shown in dotted line.
These air spaces upon compression iorce air up through perforations and 21 to the shoe interior.
In the normal usage of the shoe, the pressure of the foot on this combination of insole and overlying and underlying layers compresses the grooves and air spaces developed therein, and when the combination is iiexed in the act oi.' walking the grooves and the air spaces are further compressed and decompressed to enhance the circulation of air therethrough. To additionally secure the parts, I may provide stitching 51 which extends about and adjacent the periphery of the lamination.
By means of this construction free ilowing passage oi the air through the periorations 43, 32 and i8 or the periorations located in the grooves 42, 2| and the corresponding periorations 33 in the insole is afforded. This air is developed through the compression and iiexing of the shoe.
This application is in part a continuation of my co-pending application Serial No. 306,778, illed Nov. 30, 1939, for Novel insole and outersole combination, and the modifications shown therein of the resilient layer may be employed in the present construction.
The central portion, generally denoted as on the layer I0 and 6| on the layer Il is preferably thicker than the peripheral lap portion I3 and 64 of the layers I0 and I0 respectively, and the lap portion may comprise in lieu oi the abrupt laps here shown a gradually diminishing lap 4 which diminishes from the thickness of the cen- J tral portion 60 and 6| to a feather edge.
ing and an underlying layer of resilient material with the insole positioned therebetween I obtain o not only increased resilience and breathing properties, but I also protect the life and flexibility of the insole from the deterioration which normally results from the penetration ofA foot perspiration or dampness thereto. As is known in this art, an insole that has over a period oi.' time been subjected to dampness and drying out loses its resilience and becomes hard and dry. In this condition its flexibility is lost to a substantial extent and, in fact, a certain curling of the insole may occur. B y the protective overlying and underlying resilient layer of rubber-like material which I employ and by the forced breathing which I eect in the construction, I eliminate such difiiculties and maintain the insole in its original flexible and resilient state over an extended period of time.
It is to be understood that the constructions vshown and described above are given by way of lugs downwardly depending from said overlying resilient layer, openings through said insole and said underlying resilient layer, said lugs extending into said openings, periorations extending 5 through said overlyingresilient layer and said underlying resilient layer ior transmission oi air therethrough.
