Filed Apr. 10, 1962, Ser. No. 186,401 12 Claims. ((Zl. 36-25) The present invention generally relates to a novel and improved shoe construction and more particularly to a shoe construction having detachable components such as the uppers and heel whereby such components may be interchanged with other components thereby enabling the appearance characteristics of the shoe to be altered by interchanging the components thereof with other components having different appearance characteristics.
Generally, a relatively large wardrobe of shoes must be retained by women in order that the appearance characteristics of their shoes be compatible with the remainder of their clothing. This requires a considerable expenditure and also presents a problem in properly storing the shoes when they are not being used. Accordingly, it is one of the essential features of the present invention to provide a shoe construction having detachable uppers which may be easily detached from the sole of the shoe so that other uppers having diiferent appearance characteristics may be attached to the sole thus changing the appearance characteristics of the shoe and enabling the shoe to be adapted in appearance characteristics so that it is compatible with a particular article of wearing apparel. Also, it is a further essential feature of the present invention to provide a detachable heel construction whereby other heels may be connected to the sole for enabling the heel to be changed in appearance characteristics to not only be compatible with another garment or wearing apparel but also compatible with the uppers attached to the shoe.
Still another important object of the present invention is to provide a shoe construction in accordance with the preceding objects having a novel means for securely attaching the uppers and the heels but yet enabling easy removal and replacement of the components.
Another feature of the present invention resides in a novel manner of placing a metal shank in the portion of the sole which supports the arch region of the foot.
Still another important object of the present invention is to provide a shoe construction having detachable components in accordance with the preceding objects which enables the fastener means to be completely hidden and orientated in such a manner that a subtsantially completely smooth surface is provided for engagement with the foot whereby an inner sole placed in the shoe will completely eliminate any possible discomfort to the wearer of the shoe.
The present invention may be adapted to various types of shoes, sandals, slippers or any other type of footwear including a shoe of the type generally designated as a thong shoe which has a thong extending downwardly between certain of the adjacent toes on the foot of the wearer.
With all of the objects being accomplished, the structure of the present invention is still quite simple, easy to use, effective for its particular purposes and generally inexpensive to manufacture.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 11 is a sectional view taken generally along section line 11-11 of FIGURE 10; and
FIGURE 12 is an exploded perspective view of the construction of FIGURE 10.
Referring now specifically to the drawings, the numeral 10 generally designates the shoe of the present invention which generally includes a shoe sole 12 and an upper 14 together with a heel 16. The sole 12 includes an outer sole or outsole 18 and an inner sole 20. The outer sole 18 may be of any suitable configuration and construction and may be of any suitable material compatible with present day shoe construction. The outer sole may be of one-piece construction or may be laminated depending upon the desires of a particular manufacturer. Regardless of how the outer sole is constructed, it is provided with a peripheral recess 22 around the outer edge thereof. Mounted in the recess 22 is a fastening strip generally designated by numeral 24. The fastening strip has the outer edge thereof generally flush with the outer peripheral edge of the outer sole 18 and has the top surface thereof spaced slightly below the central portion 26 of the outer sole which has a planar surface 28 disposed in a plane above the upper edge portion of the strip 24.
The fastening strip 24 includes a bottom flange 30 that engages the bottom of the recess 22 and is secured thereto in any suitable manner such as by bonding, stapling, nailing, stitching or the like. At the outer edge of the flange 30, there is an upstanding outer edge flange 32 and at the upper edge of the upstanding flange 32 is an inwardly extending flange 34 paralleling the flange 30 thus defining a generally U-shaped strip as illustrated in FIGURE 3 with the legs of the U-shaped strip being parallel and substantially horizontally disposed. As illustrated in FIGURES 2 and 3, the upper flange 34 is slightly shorter than the bottom flange 36 thus defining a peripheral space 36 between the flange 34 of the strip 24 and the inner edge of the recess 22 for a purpose described hereinafter.
The flange 34 of the fastener strip 24 is provided with a plurality of keyhole shaped notches 38 each of which includes a substantially circular inner portion 44) and d verging edge portions 42 communicating with the inner edge of the flange 34 and with a portion of the periphery of the opening 40 which defines less than one-half of the periphery of the opening 40 thus defining a restricted entrance throat 44 for-the circular opening 40. As illuss,154,see
' 3 trated in FIGURE 2, the notches 58 are equally spaced peripherally of the sole 12 except that the toe portion thereof, the notches may be omitted since the toe portion or" the uppers is usually omitted. 1
The uppers 14 include any suitable arrangement of flexible straps as constructed of any suitable material and of any suitable color and appearance characteristics. The bottom edge of the strap as is cut generally to conform to the periphery of the inner edge of the recess 22; and each strap 46 is provided with a pair of headed fasteners 48 which have a circular flange Stl on the outer surface thereof which is spaced from but disposed closely adjacent to the outer surface of the strap as. The inner end of the fastener 48 is also provided with a circular flange 52 embedded or partially embedded in the material of the strap 46 thus defining a flush arrangement with the inner surface of the strap l6 as illustrated in FIG- URE 3.
When the straps 46 are assembled with the soles, the outer ends of the fasteners 48 are inserted into the area defined by the periphery of the recess 22 and the inner edge of the flange 34 in alignment with the notches 38. Thus, the dimension of the divergent surfaces 42 combined with the space 36 defined between the inner periphery of the recess 22 and the edge of the flange 34 provides sufficient room for passage of the headed or flanged end fill of the fastener 45 after which the fastener 48 may be moved outwardly. The circular portion of the fastener 43 will snap' through the restricted throat 4 and thus engage with the circular opening as so that force is necessary to move the fastener into or out of the notches 38. The thickness of the straps 46 is such that when it is orientated on top of the flange 34, the upper surface of the inner end portion of the straps 46 will be substantially flush with the upper surface of the sole as illustrated in FlGURE 3 thereby providing a flush surface for engagement by the inner sole Ell.
The various components may be constructed of any suitable lightweight and long lasting materials. If desired, the entire sole may be constructed of a plastic and in this event, the fastening strip may become an integral part thereof. When it is desired to disassemble the uppers, it is only necessary to move the ends of the straps 46 inwardly thus disconnecting the fasteners after which other uppers may be assembled with the sole in an obvious manner.
The heel construction 16 is of any suitable construction and the main body of the heel is designated by reference numeral 54. The top face of the heel conforms with the bottom surface of the outer sole 18 in the conventional manner but the heel has a vertically extending recess 56 therein in the form of a bore terminating in an enlarged spherical recess 58 at the inner end of the bore 56 for receiving a fastener generally designated by the numeral 60. FIGURE 5 illustrates the construction of the fastener which includes a tapered head as, a short threaded shank portion 64 and a plurality of longitudinally extending fingers or tines 6o terminating in a partial circular lower end 68. When the fingers 66 are in collapsed condition,
they define substantially a cylindrical member generally conforming with the configuration of the bore 56. The circular portions 63 are sutficiently flexible that they may be compressed and passed downwardly through the bore 56 and then expand outwardly into the spherical recess 58 as illustrated in FIGURE 4 whereby the fingers are at all times maintained under tension so that the natural resiliency of the fingers will securely fasten the heel 16 to the sole 18. The threads 64 are engaged with the periphery of an opening 70 in the sole 1% for securely retaining the fastener in place and serving as an anchor for the fastener. Inasmuch as the lower ends of the fingers engaging the spherical surface serve to cam or urge the heel and sole towards each other, the top face of the heel will be snugly and securely engaged with the bottom surface of the outer sole at all times thereby providing a rigid and secure connection between the heel and the sole and at the same time permitting removal of the heel for replacement thereof with other types of heels having different color characteristics, appearance characteristics, length or the like.
FIGURE 6 illustratesan arrangement in which a thong i2 is employed and in this construction, a socket or recess 74 is formed in the top surface of the sole '76 and the bottom end of the thong 72 is provided with a circular flange or disk '73 which is received in the wider portion of the recess "7 which is undercut and formed into a keyhole configuration after which the circular plate or disk 7% may be moved forwardly and interlocked with the narrow end of keyhole slot or recess 7'4 thereby securely and detachably locking the thong to the sole '76. In this construction, the inner sole till will be provided with an aperture permitting passage of the lower end of the thong through the inner sole for engagement with the fastening recess in the sole 76.
Thus, there has been provided a shoe construction with a rigid strip orientated around the edge of the sole and disposed in a recess therein with the top of the strip being disposed slightly below the surface of the sole so that when the uppers are attached to the strip, the uppers and the sole will be substantially flush. The uppers have a projecting fastener for en agement with keyhole notches or slots formed in the strip thus enabling quick and easy detachment of the uppers. Also, the heel may be easily detached and interchanged with other heels and the fastener construction of the present invention enables it to be employed with various types of shoes including the thong type.
A metal shank 82 is disposed in a longitudinal recess 84 in the outer sole 18 and is retained therein by a filler 86 of any suitable material such as a hardenable material which enables flexibility of this area of the shoe but also provides adequate support for the arch portion of a foot. This metal strap or shank 82 is curved to conform with the sole and provides adequate support for this region of the shoe. Also, the strip is constructed of a material capable of bending during normal walking operation but still retaining its shape and structural characteristics when in a normal condition. Also, the strip may be omitted along the side edges of the arch supporting portion of the shoe since in many instances, the uppers have no straps or other materials in this area. This also would enable the shoe to flex in a completely normal manner during walking.
Referring now specifically to FIGURES 7-9 of the drawings, the numeral 90 generally designates another form of heel connection between the sole 92 and the heel 94 which has a recess 95 in the attaching face thereof. Connected to the attaching face of the heel is a plate 98 of metallic construction which may be secured to the heel by any suitable means such as a plurality ofnails 100 or the like. The central portion of the plate 8 is provided with a slot 102 in the form of a cruciform which has four radially extending arms orientated in perpendicular relation to each other for receiving a similarly shaped projection 10 tcarried by a shank 166 extending through the sole 92. The shank 106 is threaded for a portion of its lentgh and the projection 104 is spaced slightly below the bottom surface of the heel 92 so that the radially extending arms of the cruciform projection 104 may be inserted through the slots and then rotated to a locked position. The upper end of the shank 106 is provided with a head we having a kerf or slot thereacross for receiving a suitable implement for turning the shank to lock the projection 1.04 to the plate 98. The kerf or slot is designated by numeral 116 and suitable indicia is provided on the top surface of the sole 92 as indicated by numeral 112 for indicating the open and locked position of the projection thus enabling the projection to be orientated properly for detaching the heel or locking the heel to the sole. The headed end of the shank 106 may be received in a slight countersink or recess 114 so that the inner sole 116 provides a smooth interior surface for engagement by the heel portion of the foot. This type of interlocking support or connection between the heel and the sole provides a rigid connection and one which will effectively lock the heel in place.
FIGURES -12 illustrate another form of connecting means for the heel generally designated by numeral 120 in which the sole 122 has a recess 124 in the top surface thereof and the heel 126 has a plate 128 attached to the attaching face thereof by virtue of nails 130 or similar equivalent fasteners. The plate 128 has a pair of upwardly extending bendable tangs 132 struck out from the forward and rear edges of the plate thus leaving slots 134. The tangs or lugs 132 extend upwardly through slots 136 formed in the sole 122 and also extend upwardly through slots 138 in a retaining bar 140. The retaining bar 140 is attached to the sole by virtue of any suitable fastener such as a rivet type fastener 142 extending through apertures 144 in the outer ends of the retaining bar 140. Slidable on the retaining bar 140 is a pair of loop shaped retainers 146 which slide over and retain the bendable tangs, lugs or tabs in superimposed relation to the retaining bar 140 after the tangs 132 are received in the slots 138 and bent inwardly toward each other in the position illustrated in FIGURES l0 and 11 thus forming retaining means for securing the heel in position on the sole. In this construction, the inner sole 148 also provides a smooth surface for engagement by the heel portion of the foot. The insole in the several forms of the invention may be attached to the outer sole in any suitable manner.
It is pointed out that any number of bendable tabs or tangs may be provided for example two as illustrated or four tabs may be used. Any type of locking interconnecting may be provided between the bendable tabs. If desired, rather than using the bendable tabs, tabs of a rigid nature may be employed with the tabs being hingedly connected to the plate carried by the attaching face of the heel.
In addition to the above, it is pointed out that the bore in the construction of the heel illustrated in FIGURE 4 may be filled with a self-sealing rubber or plastic material. Also, the self sealing rubber is placed on top of the sole at the heel portion and between the heel and sole to provide a seal, which will produce somewhat of a vacuum when the elements are assembled thus producing a solid connection between the components. The retaining bar 140 may be attached as illustrated or left free of the sole thus facilitating the manufacture of the heel assembly. When the sole is constructed of plastic it may be constructed in such a manner that the shank is actually molded into the sole during the molding procedure.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
