Feb. 18, 1958 SHOE Filed May 14, 1956 INVENTOR v v /rl /'l l/ ATTORNEYS United States Patent SHOE William R. Eberhart, Atlanta, Ga.
Application May 14, 1956, Serial No. 584,808
1 Claim. (Cl. 36-2.5)
The present invention relates to shoes, and more particularly to a shoe which is constructed to prevent sliding movement of the foot therein.
The primary object of the invention is to provide a shoe with means to engage the heel to prevent forward sliding movement of the foot in the shoe.
Another object of the invention is to provide a shoe of the class described above in which the device for preventing sliding movement of the foot within the shoe has no effect upon the comfort of the shoe or the support characteristics thereof.
A still further object of the invention is to provide a shoe constructed in accordance with the invention which is inexpensive to manufacture, comfortable to wear, and durable in service.
Other objects and advantages will become apparent in the following speciiication when considered in the light of the attached drawings, in which:
Figure 1 is a top plan view of the inner sole of a shoe constructed in accordance with the invention.
Figure 2 is a longitudinal cross-section taken along 'the line 2-2 of Figure l, looking in the direction of the arrows.
Figure 3 is a plan view of an insole of another type shoe showing the invention applied thereto.
Figure 4 is a longitudinal cross-section taken along the line 4-4 of Figure 3, looking in the direction of the arrows.
Figure 5 is a plan view of an element of the invention.
Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference numeral i-ndicates generally a mans shoe of the type having a sole 11, an insole 12, and an upper 13. A rectangular block 14 formed of cork, semi-hard rubber, or other suitable material extends transversely of the shoe 10 resting on the insole 12, as illustrated in Figure 2. The rectangular block 14 has its outer upper edges bevelled to eliminate sharp corners.
The block 14 is secured tor the insole 12 by cement or other suitable means (not shown). An elastic strap 15 is secured to the upper surface of the Iblock 14 intermediate its ends and has its forward end 16 secured to the insole 12 by cement or any other suitable means. The rear end 17 of the elastic strap 15 is secured to the insole 12 adjacent the rear of the shoe 10 by cement or any other suitable means.
A flexible soft sponge-like rubber sheet 18 is positioned over the strap 15 and extends from side to side of the shoe 10 terminating at its rear end 19 adjacent the rear of the shoe 10 and at its front end 20 forwardly of the front end of the resilient strap 15.
A sock lining 21 is positioned over the insole 12 at the front of the shoe 10 and extends over the sheet 18 to the rear of the shoe 10. The sock lining 21 has the central portion thereof cut out as at 22 to provide the sheet 18 70 with an exposed surface 23.
Referring now to Figures 3 and 4, the invention is shown applied to a ladys shoe 10a of the type having a relatively high heel 24. The shoe 10a has a sole 11a, an insole 12a, an upper 13a, all constructed conventionally. A block 14 identical to the block 14 illustrated in Figures 1 and 2 is positioned against the insole 12a forwardly of the heel 24. A resilient strap 15 has its forward end portion 16 secured to the insole 12a and its rear end 17 likewise secured to the insole 12a by any suitable means such as cement or the like.
A flexible resilient rubber sponge-like sheet 18 extends from the rear of the shoe 10a over the resilient strap 15 to a point forwardly of the forward end 16 of the resilient strap 15.
A sock lining 21a extends from the forward end of the shoe 10a in contact with the insole 12a overlying the sheet 18 to the rear of the shoe 10a. The central portion of the sock lining 21a overlying the sheet 18 is cut out as at 22a to permit the surface 23 of the sheet 1S to be exposed, as best shown in Figure 3.
It should be understood that in applying the blocks 14, elastic straps 15, sheets 18, and sock linings 21 and 21a to mens shoes 10 and womens shoes 10a the sizes of these element will vary in proportion to the size of the shoe. In applying the block 14 to the shoe, the resilient strap 15 is first secured to the block 14 and then stretched to its ultimate position where it is cemented to the insole 12 or 12a providing a resilient support for the foot.
The sheet 18 having its exposed surface 23 in contact with the foot or the sock of the wearer will tend to pro- Vide traction to prevent the slipping of the foot yforward in the shoe while the block 14 which projects upwardly just forward of the heel of the wearer will act as a stop to prevent the heel from sliding forward and hence will prevent the foot from sliding forward in the shoe.
'Ihe use of the present invention in a conventional shoe structure will provide the wearer with highly increased comfort since the jamming of the toes into the forward portion of the shoe will be eliminated and the shoe will lit the wearers foot in accordance with the design of the shoe.
Having thus described the preferred embodiment of the invention, it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the scope of the appended claim.
What is claimed is:
A shoe comprising a sole, an upper secured to said sole, an insole secured to said sole and having a forward portion, an arch portion, and a heel portion, a transversely extending block secured to the upper side of said insole at the extreme rear of said arch portion closely adjacent to said heel portion, a resilient flexible strap overlying and engaging said block and secured at its opposite ends to said insole at the rear of said heel portion and at the forward edge of said arch portion respectively with said strap vertically spaced from said insole adjacent said block, and a resilient cushion panel overlying said strap and said block.
