Application December 5, 1947, Serial N 0. 789,993 9 My invention relates to shoes and more particularly to shoes provided with specially constructed soles.

2 Claims. (01. 36-25) The object of my invention is to provide a shoe I having a sole consisting of sections extending transversely of the shoe.

Another object of the invention is to provide a shoe having a sole consisting of sections extending transversely of the shoe and being connected hingedly with each other.

A further object of the invention is to provide a shoe having transversely extending, hingedly connected sole sections which are made from wood, metal, plastic or any other suitable strong and wear resisting material.

Other objects of the invention may appear in the following specification describing my invention with reference to the accompanying drawings illustrating a preferred embodiment of my invention. Y

It is however to be understood, that my invention is not to be limited and restricted to the exact construction and combination of parts described in the specification and shown in the;;;., drawings, but that such changes and modifica- 25 tions can be made which fall Within the scope of the claims appended hereto.

In the drawings:

Figure 1 is a side elevational view of a shoe according to my invention.

Figure 2 is a sectional view taken on line 2-2 in Figure 1.

Figure 3 is a vertical longitudinal sectional view of the shoe shown in Figure 1.

Figure 4 is a bottom plan view of Figure 1.

Figure 5 is a sectional view taken on line 5-5 in Figure 3, and

Figure 6 is a sectional detail view taken on line 6'6 in Figure 2.

central portion I8 supporting the arch of the foot and a rear portion l9 supporting the heel of the foot. Between the front-portion i1 and the middle portion [8 and between the middle por tion i8 and the rear portion i9 the inner sole I5 is provided with zones of reduced thickness as indicated at and 2| respectively to increase the flexibility of the sole, and these zones extend transversely of the inner sole.

' The rim portion 22 of the upper structure III is bent outwardly to form a-flange resting on the circumferential portion 23 of the inner sole [5. A connecting member has a channel shaped cross section and is formed to extend around the toe portion of the shoe back to the flexing zone 20 of the inner sole. Another connecting member 25 of similar construction is arranged at the heel end of the shoe and extends forwardly to the flexing zone 2| of the inner sole i5. On each side of the shoe a connecting member 28 having a channel-shaped cross section extends between the flexing zones 20 and 2| of the inner sole 15.

The superimposed rim portions 22 and 23 of the upper structure I0 and the inner sole l5 re-' spectively are located inside the connectin members between the flanges thereof.

The sole of the shoe according to my invention is preferably made from wood, metal, plastic or 0 any other suitable Wear resisting material and Referring now in detail to the drawings the 40 shoe accordin to my invention has an upper structure in of conventional design or construction and made from any desired and suitable material, such as leather, canvas or the like.

The shoe can be fastened to the foot of a wearsupporting the toes and the ball of the foot, a 56 consists of a toe supporting portion 21, an arch supporting portion 28 and a heel supporting portion 29.

The arch supporting sole portion 28 extends between the two flexing zones 20 and 2| respectively of the inner sole I 5, the toe supporting portion 21 is arranged in front of the arch supporting portion and the heel supporting portion 29 in the rear thereof.

A plurality of screws 38 extends through the several connecting members 24, 25, and 26, and the superimposed rim portions 22 and 23 of the upper structure I9 and the inner sole [5 and into the respective sole portions 21, 28 and 29 firmly connecting the several parts forming the shoe.

The several sole portions 21, 28 and 29 are connected hingedly with each other.

On the inner ends of the toe and heel portions 21 and 29 respectively of the sole a bracket 3! having a channel-shaped cross section is fastened. Each bracket 3i has a top and a bottom flange 32 extending transversely of the sole portion and set into recesses in the sole portions provided for this purpose, so that the upper and lower Each bracket 33 on the arch supporting sole portion 28 has on its longitudinal center a pair;

of outwardly extending, spaced apart lugs 36 and on each lateral end a bifurcated laterallyand' outwardly extending arm 31.

Each bracket 3| has an inwardly extending.

lug 38 located between the-oppositelylocated.

pair of lugs 36 and on each of" its lateral ends an inwardly extending lug 39 arranged 1in-the;,.

arranged directly underneath the flexing zones of.

the inner soles, and since the connecting. members are divided right above the hinge connections a comfortable, easily flexible shoe is provided.

Having describedmy invention 1 claimas new and; desire to secureby Letters Patent:

1-. A shoe comprisingan upper: having a flexible; inner-sole,. an outer-sole underlying said inner-sole and secured-thereto, saidouter-sole comprising a pair of end sections arra-nged. in endrto-end spaced relationwith respect. to each other,, an intermediate section. interposed in the space between said end sections and having each of itsends pivotally. connected to the. adjacent end of. said end sections, saidendandiintermediateesections beings of the. same. height and. fabricated of inflexible. material and a padding coextensive with and secured to said inner-sole, said padding having transversely-extending areas of reduced cross-section overlying the pivotally connected ends of said sections offering reduced resistance to flexing or" said inner-sole in the regions of said pivotally connected ends of said sections as the latter are moved relative to each other.

' 2'. A, shoe comprisinganupper having a flexible inner-sole; an outer sole underlying said inner-sole and secured thereto, said outer-sole comprising a pair of end sections arranged in end-to-end spaced relation with respect to each other; an intermediate section interposed in the space between said end sections, hinge means extending between the facing ends of said end and intermediate sections and connected thereto, said hinge means comprising interlocking lugs carried by the facing ends of said end and intermediate sections and a pin extending through said interlocking lugs, anda padding ac-extensive with and secured to said. inner-sole, said padding having transversely extending areas oi reduced cross-section overlying the pivotally connected ends of said section's offering reduced resistance to the flexing of said inner-sole in the. region of said pivotally connected ends of said sections as the latter are moved'relative to each other.
