9 Claims.

Our invention relates to a shoe construction and more particularly to an improved arch supporting device for curing foot ailments including prevention and correction of a large number of various disabilities and weaknesses commonly referred to as fallen arches.

In one method of prevention and cure of fallen arches, an upwardly extending dome is placed at the bottom of the shoe in a position centrally located in the longitudinal and transverse directions relative to the metatarsal arch of the wearer. When the heel is placed upon the ground the device affords the navicular bone, the first, second and third cuneiform and cuboid bones a considerable measure of support by cantilever action. When the Weight is transferred toward the front part of the foot, the toe is brought into supporting relation with the ground at which time both the tarsus and the metatarsus are supported by beam action, the primary support from the arch being through the dome.

In accordance with the present invention an improved arch support structure for providing this action is achieved by use of a lengthy plate extending along the bottom of the shoe from the heel to a point where the dome is desired. This plate is provided with a centrally disposed notch at the forward edge thereof together with an opening near the foot of the notch to receive a cooperating support member. The support member is provided with a backwardly extending tongue to be received in the notch and a downwardly extending tongue to enter the opening and fix the position of the support member relative to the plate. A cushion of rubber or similar material is pressed underneath the forward edge of the support member which is bent back for the purpose and extends backwardly thereover to form a cushion for the dome over the parts.

It is accordingly a general object of the present invention to provide an improved shoe having an arch support for the prevention and cure of the maladies commonly referred to as fallen arches.

Another object of the present invention is to provide an improved shoe having an arch support for the prevention and cure of the maladies commonly referred to as fallen arches and in which the separate cooperating parts are held in fixed relation relative to each other.

Yet another object of the present invention is to provide an improved shoe having an arch support having a dome for the prevention and cure of fallenarches and in which the dome is pro- 2 vided with a suitable cushion for the support of the wearer with a maximum degree of comfort.

Still another object of the present invention is to provide an improved arch support that is read ily assembled to provide resistance to downward flexure but which is free to execute limited upward flexural movements and has no tendency the following description taken in connection with the accompanying drawings.

On the drawings:

Figure 1 is a phantom view showing a shoe equipped with the structure of the present invention and showing that structure in axial cross section;

Figure 2 is a top plan view of the structure of the present invention;

Figure 3 is an enlarged View of the end portion of the plate portion of the present invention showing the notch and opening provided to engage cooperating parts of the support member;

Figure 4 is a top plan View of the support portion of the structure; and

Figures 5 and 6 are cross sectional views through axes 5 and 6, respectively, of Figures 3 and 4.

As shown on the drawings:

Referring to the phantom view of Figure l, the foot of the wearer is shown at F and the shoe indicated at S. The latter comprises a heel portion H from which the heel of the wearer is supported above the supporting surface and a toe portion T which supports the toe of the wearer at a closer point to the supporting surface. An outsole l0 extends along the bottom of the shoe to form a wearing surface for the bottom thereof.

The plate l2 rests upon the outsole portion III of the shoe S and extends from the heel H forwardly to a point centrally located relative to the metatarsal arch of the foot F. A support plate member Mv is located at the forward end of the plate l2 and the cushion l5 rests upon the upper surface ofthis plate to provide a resilient dome to support the foot of the wearer at a" point centrally disposed longitudinally and trans versely relative to the metatarsal arch. An insole I8 is located between the plate I2, the cushion I6 and the foot F to provide a neat appearance and to give the wearer further protection against any edges in the plate I2 or the cushion It.

The general structure of the plate I2 will best be understood by reference to the top plan View of Figure 2. -As is evident from this figure, the plate I2 is provided with a plurality of holes I8 to accommodate nails or other devices to attach the plate to the shoe. A plurality of longitudinally extending ribs 20, 22, and 2d are pressed into the plate to provide added rigidity in the horizontal direction. At the front end, the plate I2 is notched as shown in Figure 3; the notch being of generally square shape as indicated at it; with bottom portion 28. Turneddown edge portions 30 of plate I2 are positioned in alignment with the notch and form a support for the two side tongues formed thereby. The structure of these portions will further be evident from the side viewof'Figure'fi.

In-addition to the foregoing elements; the plate I2 is provided with a'rectangular opening 32 centrally disposed relativeto the :axis thereof at a point close to the bottom-28 of notch This opening receives a corresponding downwardly extending tongue in member I ito prevent shift of the latter.

.Thestructure of the support member I i is best seen in the top planview of Figure-2 which shows itiin cooperating relationship with the plate I2 and the top and cross sectional views of Figures 4 and 6 which show thismember and the cushion I6. As will be evident from these figures, the member I4 is provided with a rearwardly extendingtongue 34 of transverse dimension'slightly less-than that of the notch 28 to be received therein as indicatedwinFigureQ. As will be apparent from the cross sectional view of Figure 6, this tongue is of substantially :flat shape and has atits rear end a downwardly extending tongue 35, this lattertongue being of lateral dimension to fit in the opening 32 provided in the forward end of the plate I2.

The support member l l is further provided with two depressed portions fifi'adjacent the root of tongue "34 and which lieunderneath and inside the turned down edge portionsflil at the forward end of the plate- I2, thus providing support for member :14 against downward fiexure relative to plate I2.

On its forward end, the support member It comes down to a fiat-portion 38,- Figure 6, which isbent back upon itself in the upward direction to wrap around the forward edge of the cushion I6 as indicated at 4!). This portion is pressed down tightly overthecushion Iii-to hold'that cushion securely relative to the other portions of the mechanism.

The cushion I6 is of resiliently deformable material such as rubber composition to rest over member I4 and forms a domewith the desired degree ofresistance to-flexure. It is of generally semi-circular shapewwith the forward edge shaped to be gripped by the forward edge 4b of member ii.- andextending backwardly over the member I l. Preferabl the cushion I6 is of relatively soft resilient material, such as soft rubber, although harder materials suchasrelatively harder rubher-may be used ifless resilience is desired.

- -ln the assembled; 'position'the' support member Ill-islocated with its tongue portion tdextending backwardlyinto :the notchzii of plate I2 andwith its ed e portions 36 passing underneat the edge portions 30 of the plate l2 as shown in Figure 2. The downwardly extending tongue 35 is dropped into the opening 32 of the plate I2, thereby forming a tongue and opening connection which holds member It in fixed position relative to the plate I2 and opposes relative shifting thereof. The plate I2 is then fastened to the sole II] by driving nails through openings I8 or similar means, the entire unit covered with cement (42, Figure 1) and the insole I8 attached. The cushion I6 then extends upwardly over the support member I l to form the resiliently deformable dome directly under the metatarsal arch of the wearer.

The downwardly extending tongue 35 and the backwardly extending tongue 36 of member I4 fix the position of that member against shifting relative to the plate I2. Member I l and plate I2 further oppose downward flexure because of the engagements between the overhan ing edges of tongue 34 and the portions of plate l2 immediately thereunder and the engagements between the edges 35 of member Id and the forwardly extending tongues ill of plate I2. However, there is no opposition to limited upward fiexure of the plate I2 relative to member I4, and thus there'is no tendency to create noise as the walking takes place.

While we have shown a particular embodiment of our invention, it will of course be understood that we do not wish to be limited thereto since many modifications both in the elements disclosed and their cooperative structure may be made Without departing from the spirit and scope of our invention. We, of course, contemplate by the appended claims to cover allsuch modifications and alternative constructions as fall within the true spiritandscope of our-invention.
