ATTORNEYS United States Patent 3,313,048 CUSHION SHOE William A. Beisner, Waupuh, Wis., assignor to Mid-States Shoe Co., Milwaukee, Wis. Filed Apr. 14, 1964, Ser. No. 359,714 1 Claim. (Cl. 36-17) This invention relates to comfort and physical wellbeing, especially of the human foot.
The invention more particularly relates to an improved shoe having a combination of features adapted to promote enhanced comfort not only after the shoe is broken in but beginning with its initial wearing, whereby fatigue and disorder resulting from the wearer being on his feet for long periods of time will be minimized.
Footwear has been designed for many years with the object of comfort and durability, various features having been employed for such purpose. However, despite the advances that have been made and the recognition of the desirability of various features, the combining of the several features into a highly attractive, durable shoe having outstanding comfort characteristics has not heretofore been achieved to the desired extent.
Accordingly, it is an object of the present invention to provide a shoe of superior appearance and durability in which various features contributing to improved comfort are combined in a novel manner.
A further object is to produce a shoe of superior appearance having an insole adapted to conform more nearly to the sole of the foot including the arch, having improved cushioning of a character designed to remain in place instead of shifting over a period of time and and in which the heel is firmly secured without the possibility of any nails or portions thereof protruding.
These and other objects of the invention will become apparent from the following description in conjunction with the accompanying drawing, in which:
FIG. 1 is an elevation with a portion in section of a shoe made in accordance with the present invention;
FIG. 2, a plan view of the insole;
FIG. 3, a section on the line 33 of FIG. 2; and,
FIGS. 4, and 6, enlarged sections on the lines 4-4, 55 and 66 of FIG. 1.
Briefly stated the shoe of the present invention includes a relatively thick, supple insole having an integral portion beveled and extending across and up into the arch portion, but not attached to such arch portion, a rib channel cemented around the bottom of the insole, a welt sewed through the upper and the rib around the entire periphery, the insole overlying the joint between the welt, the upper and the rib, thereby providing a continuous, smooth integral pad on which the foot rests, absent any lines of demarcation, sewing or nails, an air porous resilient cushion which breathes positioned within the boundaries of the rib, a metal shank positioned beneath the cushion, a plate positioned beneath the heel portion, the outsole positioned over the plate, the shank, the cushion and the periphery of the connected welt, upper and rib, said outsole sewed to said welt, and a heel having a core connected to the heel portion of the outsole by barbed n-ails which are driven in with the heads up to the core and the points penetrating the outsole and up to the plate, said plate preventing any identations in the heel which might cause discomfort to the wearers heel.
With further reference to the drawing, the shoe in accordance with the present invention has a relatively thick, flexible bend leather insole 10, having a bottom portion 11 and an arch portion or lateral extension 12 extending upwardly in free contacting relation with the adjacent wall of the shoe upper (FIG. 5). The insole is preferably relatively thick, the bottom portion about 4 /2 irons, and
3,313,048 Patented Apr. 11, 1967 the arch portion beveled and tapered to reduced thickness.
In manufacturing the shoe the bottom portion of the insole is coated with a permanent bond cement of the heat activated type. An angular rib 13 of thin flexible material, such as fabric, having a relatively wide inner side portion 14 and a relatively shorter downwardly extending or outer side portion 15 is attached with the use of heat to the bottom portion of the insole around its rim. The portion 14 of the rib extends inwardly of the insole a substantial distance such as one-half inch, whereas the portion 15 ex tends outwardly a much smaller distance such as oneeighth inch.
The insole is then tacked to the bottom of the last (not shown) and the upper 16, the lining 17 and the counter 18 at the heel portion are temporarily tacked to the bottom of the insole. Then the upper is stretched over and pulled tight to the last and stapled to the rib. The heel and toe are formed and held in place by conventional means, the heel being sewed and the toe being secured by a monofilament wire (not shown).
A leather welt 20 is then attached by stitching 21 to the rib 13, the welt extending around the entire shoe.
The tacks holding the insole to the last are removed and the shoe bottom is then trimmed to remove excess material and the seam is rubbed to flatten the bottom.
Then the bottom of the insole which is exposed is cemented and cushion 23 is placed in the cavity within the rib 13, such cushion extending to cover the space within such rib and connected to the insole by the cement.
The cushion is of a resilient material such as foam rubber having minute air pockets so that it breathes. Due to the cementing of the insole bottom to the rib and to the cushion, it will be seen that the cushion is held in position with respect to the upper and the insole and cannot shift. In particular, it cannot move forward as occurs with cork fillers of the type commonly used.
An elongated stiffening shank 25 of outwardlyflaired shallow channel section (FIG. 5), ordinarily of steel, is next positioned in the arch portion of the sole on the outer side of the cushion 23 with the outwardly fiaired edge portions of the channel section substantially embedded therein. Then a plate 26 (see FIG. 6) is attached by cement over the nailing area of the heel seat portion of the shoe. The plate is of a relatively hard or n'gid fiber of a character suflicient to resist the penetration of a nail. A layer of cork 27 may be positioned between the cushion 23 and the plate 26 at the heel seat.
The welt is then cemented and the outsole 28 is laid to the bottom of the shoe, after which surplus outsole and Welting are trimmed and the outsole then further secured by stitches 24 to the welt around the entire shoe, thereby eliminating any nailing of the outsole to the shoe. After further shaping the heel structure 29 is attached.
The heelstructure 29 (noting FIGS. 1 and 6) comprises a lower wear-resisting portion 30, preferably of rubber, having a flat-bottomed recess in its upper surface extending over its major extent with a flat core member 31, preferably formed of relatively hard wood, filling the recess and disposed flush with the top surface of the lower heel portion 30. The upper. heel portion which may also be of rubber and having a relatively large central aperture (FIG. 6) overlies and is in intimate contact with the upper surface of the lower heel portion 30 and its core 31, the upper heel portion having bearing contact with the shoe outsole 28. Heel 29 is connected by barbed nails 32 which are pushed through the rubber and driven through the flat core member 31 with their heads up to and prevented from further movement by the core 31, the barbs penetrating and being imbedded in the outsole 28. The nails 32 are of a length such that with their heads against the core member, as shown, their points just reach the plate 26 in order to provide maximum holding attachment to the outsole. The plate 26 resists any penetration from the nails which might produce a protrusion within the heel portion of the shoe upper. Accordingly, it is not necessary to provide for clinching the points of the nails as in conventional practice. 7 The shoe is then finished up in the conventional manner to provide an article of attractive appearance.
Accordingly, it will be seen that the insole of the shoe provides a cushion without any nails or sewing exposed and that the main portion of the bottom thereof is supported on a cushion attached thereto which breathes with the action of the foot, the shoe being welted around its entire periphery, eliminating any nails for attaching the sole and improving the apperance, the shoe being flexible due to the suppleness of the components including the insole, the cushion and the rib, and the heel being attached in such a manner that the nails cannot produce protuberances, whereby the entire sole of the foot is re' ceived in a conforming flexible insole without any nails, stitching, seams or overlapping of material. The extension or arch portion of the insole conforms to the arch,
of the foot but is not attached to the adjacent lining of the arch portion of the shoe, thereby permitting adjustment of the insole arch portion to the bottom of the foot.
It will be obvious to one skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is illustrated in the drawing and described in the specification, but only as indicated in the accompanying claim.
What is claimed is:
A shoe having an upper including sole, arch, heel and counter portions and comprising in combination:
a pliable relatively thick insole of uniform thickness throughout its entirety extending the full length of the shoe and disposed in intimate peripheral contact with the lower extremity of said shoe upper,
