URBAN URBANY BY July 17, 1962 3,044,190 u. URBANY INFLATABLE SOLE AND HEEL STRUCTURE WITH REPLACEABLE TREAD PORTIONS Filed Dec. 18, 1959 2 Sheets-Sheet 2 52 82 Fig. 5

INVENTOR.

URBAN URBANY ilnite The present invention relates generally to footwear and more particularly to inflatable sole and heel structure with replaceabletread portions.

The primary object of this invention is to provide a foot supporting structure for a shoe or boot, specifically the sole and heel thereof, incorporating air inflatable cushion chambers and easily replaceable tread portions.

Another object of this invention is to provide sole and heel structure in which the cushion chambers are inflated through simple self-sealing valves integral with the structure.

A further object of this invention is to provide sole and heel structure in which the tread portions are held in place magnetically and are automatically located and aligned in proper position.

Finally, it is an object to provide sole and heel structure of the aforementioned character which is simple, safe and convenient to use and which will give generally elficient and durable service.

With these and other objects definitely in view, this invention consists in the novel construction, combination and arrangement of elements and portions, as will be hereinafter fully described in the specification, particularly pointed out in the claim, and illustrated in the drawings which form a material part of this disclosure, and in which:

FIGURE 1 is an exploded perspective view, cut away, of a heel structure;

FIGURE 2 is a sectional view taken on the line 2-2 of FIGURE 1;

FIG. 3 is a sectional view taken FIGURE 2;

FIGURE 4 is a top plan view of a sole structure; and

FIGURE 5 is a sectional view taken onthe line 55 of FIGURE 4.

Similar characters of reference indicate similar or identical elements and portions throughout the specification and throughout the views of the drawings.

Referring now to FIGURES 1-3 of the drawings, the base element of the heel is made of two parts, a heel base 12 and a lower heel portion 14- shaped in the manner of a conventional heel. The heel base 12 has a large cavity 16 in the underside thereof, leaving a depending, peripheral wall 18, While the lower heel portion 14 has a large cavity defined in part by a bottom wall 20 with an upstanding, peripheral wall 22, said walls having confronting faces of corresponding size and shape and said lifts being secured together in sealed relation by cement ing or otherwise bonding said confronting faces of the walls. To facilitate assembly, the wall 22 has a plurality of small sockets 24, the wall 18 having a plurality of correspondingly dimensioned and positioned raised portions 26, which fit into said sockets and align the top and bottom lifts of the heel. The air chamber 27 thus formed in the heel 10 is inflated through a small valve 28 fixed in the front, generally flat wall 30, the valve illustrated being a readily available type made of rubber or similar resilient material and having an opening "32 in which are two spaced diaphragms 34 and 36, the space between the diaphragms being filled with an air drying sealing fluid 38. Inflation is accomplished by means of -a thin probe attached to an air hose 42, the probe being forced through the diaphragms 34 and 36, as indicated in broken line in FIGURE 2. When the probe 46 is withdrawn, the

partially on the line 3-3 of btates atent small holes close and are sealed by the fluid 38. This type of valve is simple and especially suitable for the purpose, but it should be understood that other valves may be used if so desired.

The base element of the heel 10 is preferably made from substantially resilient material to obtain maximum cushioning effect and good wearing qualities are ensured by the use of a replaceable wear lift 44 of suitable wear resistant material, such as hard rubber or leather. The top surface of the wear lift 44 is provided with an endless raised rib 46 spaced slightly inwardly from the outer edge, the lower surface of the bottom lift 14 having a correspondingly dimensioned and positioned groove 48, so that the tread portion fits accurately into place on the base element of the heel. To simplify replacement of the tread portion 44' when necessary, the bottom wall 20 of the base element of the heel or more specifically of the lower heel portion 14 is impregnated with magnetic material 50 adjacent the lower face thereof, and the tread portion or wear lift 44 has its upper part impregnated with magnetic material 52, so that the tread portion is strongly attracted to the heel and held securely in place during normal use. When displaced accidentally, the tread portion 44 is easily fitted back into place.

Similar structure may also be applied to a sole 6%, as illustrated in FIGURES 4 and 5, said sole comprising an upper sole portion 62 and a lower sole portion 64. The upper sole portion 62 has a cavity 66 surrounded by a depending peripheral Wall 68, while the lower sole portion 64 has a cavity defined in part by a. bottom wall 70 and an upstanding peripheral wall 72, the wall 72 having sockets 74 and the wall 63 having a correspondingly dimensioned and positioned protuberant portion 76 for alignment, as previously described. The air chamber 77 in the sole is fitted with a valve '78, similar to the valve 28, in the rear section of the composite wall comprised of the Walls 68 and 72.

Attached to the underside of the bottom Wall 79 is a replaceable wear sole portion 80, having a raised rib 82 which seats in a corresponding groove 84 in the bottom wall 79, said bottom wall 7d being impregnated with magnetic material 50 and said tread portion also containing magnetic material 52.

The sole and heel can be attached to a conventional shoe or boot upper in any suitable manner to provide a comfortable cushioning effect and the pressure in the air chambers 27 and '77 can be changed as necessary to suit the wearer. Due to the replaceable tread portion, the wear on the cushioned sole and heel structure is minimized.

The operation of this invention will be clearly comprehended from a consideration of the foregoing description of the mechanical details thereof, taken in connection with the drawings and the above recited objects. It will be obvious that all said objects are amply achieved by this invention.

It is understood that minor variations from the form of the invention disclosed herein may be made without departure from the spirit and scope of the invention, and that the specification and drawings are to be considered as merely illustrative rather than limiting.

I claim:

The combination in a shoe having a sole portion and a heel portion: each said portion having a base element; at least one of said base elements having an air chamber defined on the lower side thereof by a bottom wall; said bottom wall being impregnated with magnetic material; and a wear surface having the upper part thereof impregnated with magnetic material and thereby removably secured to said bottom wall.
