June 21, 1966 R. LINTON 3,
VENTILATED SHOE Filed Dec. 25, 1963 INVENTOR ROSCOE Ll NTON BY-%7Z/ ATTORNEYS United States Patent 16 Claims. 01. 36-3) This invention relates to a ventilated shoe.
It is an object of the invention to provide a practical shoe having air vents below the wearers foot.
The invention is illustrated by way of example in the accompanying drawings in which:
FIGURE 1 is a perspective view of a shoe;
FIGURE 2 is an enlarged sectional view of part of the shoe, taken along the line 22 of FIGURE 1;
FIGURE 3 is an enlarged perspective view of the shoe of FIGURE 1 with parts broken away and pulled apart to reveal the construction.
The shoe illustrated in the drawings has a rubber or leather outsole l, a heel 2, a composition midsole 3, an interior liner or insole 4 (having three layers more fully described'below), and an upper 6. The upper has a finishing strip 6a stitched around its top edge. A tongue 6b forms part of the upper. At the rear of the shoe is a heel strap 8, and between the insole 4 and the midsole 3 is the usual metal supporting shank 9. The midsole 3 is cemented against the outsole 1, and the insole 4 against the midsole 3, the bottom edge 6c of the upper (FIGURE 2) being cemented above the midsole between the latter and the peripheral edge of the insole.
The midsole 3 has in its under surface a plurality of parallel linear slots 3a. extending transversely -of the shoe from one edge to the other. Because the upper is fixed above the midsole, the ends of these slots are not blocked by the upper, but rather are visible at either side of the shoe. The midsole 3 has a smooth upper surface save for a plurality of spaced apart circular holes 3b extending downwardly through the midsole, the diameter of each hole being large enough for each hole to intercept more than one of the slots 3a. Thus, the sole structure consisting of the outsole l and midsole 3 provides a plurality of passages with inlets (at the ends of the slots 3a) along the edges of the sole structure, and with outlets in the top surface of the midsole 3.
The insole 4 also has a smooth top surface save for a plurality of spaced apart circular holes 4a extending downwardly through the insole, and several of the holes 4a register with holes 3b. Thus air can pass into and out of the shoe, beneath the wearers foot, through the holes 4a and 3b and the slots 3a. Small arrows in FIGURE 3 indicate air flowing into the shoe.
The insole has a bottom layer 4b of reconstituted leather which renders the insole sufficiently stiff that it does not I deform downwardly to any serious extent into the midsole holes 3b and become bedded therein. Above the relatively stiff layer 412 is a soft, compressible middle layer 4c of latex foam, preferably about A inch to /s inch thick. This layer provides a cushion of resilient material that alternately compresses and expands as the weight of thewearer shifts to and from it, to cause alternate inflow and expulsion of air into and from the interior of the shoe through the holes 4a and 3b and the slots 3a. Above the middle layer 4c is a top layer 4d of English kip, the kip extending at the edges downwardly around the edges of the layer 4c and under the bottom layer 4b, as at 4e. The holes 4a should be of small transverse dimensions so that the top surface of the liner 4 feels smooth and is comfortable to the foot; preferably, there fore, the h0les 4a should not exceed about A; inch in diameter.
3,256,621 Patented June 21, 1966 The midsole holes 3b are of larger diameter than the holes 4a, but the holes 4a are more closely spaced than the holes 3b; this arrangement ensures that when the insole is laid onto the midsole several of the holes 4a and 3b will be in registration. In laying the insole the latter can if necessary be shifted slightly with respect to the midsole so that at least about a dozen of the smaller diameter holes 4a are aligned with larger ones 3b. The holes 3b are preferably about inch in diameter, but if they are much larger the insole 4 may, in
localized areas above the holes 3b, deform substantially into the holes 3b and cause the insole to feel irregular and uncomfortable to the foot. The purpose of the stiff lower layer 4b of the insole, resting on the generally smooth upper surface of the midsole, is to provide a firm base on which the cushioning layer 40 can pump air into and out of the shoe.
The ventilating holes and passages of the shoe are provided in the fore part of the shoe, where the foot tends to perspire the most. Holes 4a are provided through the insole rearwardly from the fore part of the shoe to increase the cushioning action of the insole and thus increase the amount of air that is pumped into and out of the shoe as the wearer walks. It is preferred to have none of the larger holes 3b directly below the ball of the foot, for in this area there is great downward pressure on the insole, and such pressure might deform the insole into holes in the midsole. The holes 3b are preferably spaced inwardly from the peripheral edges of the midsole, and cement is preferably applied along only the edges of the top surface of the midsole so that it does not run down the holes 3b and clog the slots 3a.
The slots 3a' are provided in the under surface of the midsole, because if placed in the top surface they would render the surface less smooth, and they would also be more easily clogged with cement. The slots 3a are preferably narrow to impede entry of foreign matter, but they can be fairly close to one another to provide numerous air passages. Slots about inch wide and 4 inch deep have been found to be satisfactory, with their center lines or axes about inch apart. Being above the outsole 1, the slots 3a are spaced upwardly from the bottom surface of the shoe by the full outside thickness, so that dirt and water will not ordinarily enter them in serious amounts. It is an easy matter to cut the slots 3a and to punch the holes 3b and 4a with inexpensive and readily available machinery, so that the manufacture of the shoe illustrated in the drawings does not present any serious problems. It will be obvious that the construction may be varied from the one specifically illustrated. For example, a Goodyear welt or stitchdown construction could be used to secure the upper above the midsole, the materials mentioned herein could easily be varied, and the shapes and arrangement of the ventilating holes and passages may be varied within the scope of the subjoined claims.
