J. SCHALLER May 29,. 1934r ORTHOPEDIC sHoE Filed DSC). 24, 1930 f2/zing fc/Liner Patented May 29, 1934 UNITED STATES PATENTS OFFICE Application December 24, 1930, Serial No. 504,461 In Germany January 4, 1930 C 1 Claim.
The orthopedic boots and shoes of well known construction get a step-face of an anatomic and plastic character by means of recessed portions and increased portions within the inner sole which are obtained by cutting them out or by intermediate piles or layers.
The present invention relates to orthopedic boots and shoes and it is the principal object of my invention to provide recesses and increased portions within the step-face or within the sole by means of layers.
Another object of the invention is the provision of layers Within the sole having recessed portions with sloping edges.
A still further object of the invention is the provision of intermediate layers for the purpose of vaulting the middle foot bones.
These and other objects and advantages of my invention will become more fully `known as the description thereof proceeds, and will then be specifically pointed out in the appended claim.
In the accompanying drawing forming a material part of this disclosure:-
Fig. 1 is a view from beneath of the sole with the layers one upon another, partly in section,
Fig. 2 is a section on the line II-II, Fig. 1,
Fig. 3 is a section on the line III-III, Fig. 1,
Fig. 4 is a section on the line IV-IV, Fig. 1.
Referring to Fig. 1 of the drawing, it will be seen that the sole consists of two or a plural number of layers cub and the inner sole c. From the layers the necessary recessed portions d ac- (ci. 31a- 71) e are provided for the purpose of raising the middle foot bones.
After having finished these layers, the inner sole c is positioned, to lie over the respective recessed portions upon the supporting pieces and 50 by means of a pressure operation is made to conform to them. ,Y
The recessed portions or cavities d are sloped on the edges within the separate layers vso that y smooth surfaces on meinner sole are obtained. 55 Such a shoe fixed with supbUlffiigdpeues-and sloping edges for passages is relatively solid and permits the quickest possible manufacturing because the pressing of the inner sole can be made in a sole operating procedure. fm
It will be clear that changes may be made in the general arrangement and in the construction of the minor details of my invention such as fall within the scope of the appended clairnwithout departing from the spirit thereof.
Having thus described my invention, what I claim as new and desire to secure-byr Letters Patent isz- In an orthopedic shoe' including an inner sole having raised portions and depressions formed 80 therein to conform to the formation of the sole of a foot, comprising below said inner sole two layers preferably of equal thickness throughout and each having bevelled-edge recesses for the formation of raised parts and depressions to supwg/ port and to form the raised portions and depressions of the inner sole, and bevelled edge supporting portions or inserts adapted to bulge the insole to support the anterior metatarsal arch cording to the desired anatomic-plastic form of 0f the foot, 90
the step-face are taken out. Supporting portions JOHANNES SCHALLER.
