Cl. 362.5 30 Claims ABSTRACT OF THE DISCLOSURE Footwear upper section detachably attached to the sole, slidable, resilient, and adjustable features, attaching structure, attaching and covering sole layer, with resilient characteristics.

My invention pertains to footwear and to parts thereof, including sole and upper sections, and means for imparting adjustability so as to afford improvements in fit and appearance as well as to provide convenience and adaptability in use. The present application is a continuation of my co-pending applications, Ser. Nos. 601,217 and 601,216, filed Dec. 12, 1966. The present application is a continuation-in-part of my applications as follows: Ser. No. 601,215, filed Dec. 12, 1966; Ser. Nos. 56 2,0511, 562,056, and 562,053, filed June 13, 1966; Ser.

No. 679,887 filed Aug. 23, 1957.

In accordance with the invention, these general objectives are obtained by providing an article of footwear in which the relative positions of sole and upper portions are variable. Sliding movement, resilient means, connecting sections which are variable in length, and detachable connections are employed.

The features of my invention apply to footwear of every kind. Details, such as the construction of the sole, can vary. For instance, a sole may have a single layer in some footwear while in other footwear a sole may consist of an outersole, innersole, shank tuck, and heel tuck all cemented together. My invention applies to all types.

The term resilient, as used herein, pertains to any type of resilient element, including elastic fabrics and metal and plastic springs and their functional equivalents.

In the accompanying drawings, there are shown illustrative embodiments of the invention from which these and other of its objectives, novel features, and advantages will be apparent.

FIGURE 17 shows a fragmentary top view of the sole of FIGURE 15 with a rear section of upper detachably attached, and a fragmentary view of the rear of a cover section with the top layer turned back to disclose the attaching part,

FIGURE 18 shows a perspective view of the upper section and cover section of FIGURE 17 with a connection between the attaching parts of each.

The shoe illustrated by FIGURES 1 and 2 consists of a generally indicated sole 20 to which a heel 2-1 and avamp 22 are attached. The sole 20 is shown as including ashank tuck 23 extending from the rear of the shoe to the front of the shank and an additional layer orshank tuck 24 and hassockets 25 and 26, the former in the shank area and the latter in the heel area. Thesocket 25 has an elongated, forwardly openingslot 25A and thesocket 26 has an elongated, rearwardly openingslot 26A. Theshank tuck 23 is a customary shank stiffening layer which, in the old shoe making processes, is usually cemented to the remainder of the inner sole assembly, and attached before lasting, while theshank tuck 24 would ordinarily be attached as by cementing, together with thesockets 25 and 26, after the shoe has been lasted. In newer procedures, as in string-lasting, the entire innersole assembly would be cemented into the shoe after lasting.

A rear part upper assembly consists of aheel section 27 having a closedbottom 28 to the undersurface of the forward margin of which is secured, as by cementing, asection 29 of elastic webbing or goring. Aforward tab section 30 of inelastic material, attached to the front margin of the goringsection 29, is provided with a downwardly disposedstud 31 for attachment to thesocket 25. Afiller layer 32, secured to the undersurface of thebottom 28 of theupper section 27 in abutting relation to the rear edge of the goringsection 29, has a downwardly disposedstud 33 for attachment to thesocket 26.

It will be noted that the rear part upper assembly is shown as so dimensioned that the goringsection 29 yieldably maintains thestuds 31 and 33 against the closed ends of thesocket slots 25A and 26A, respectively, while enabling theheel section 27 to have a substantial range of sliding movement relatively to the heel section of the sole rearwardly from its position of rest, theslot 26A being so designed and so dimensioned in length as to permit theheel section 27 to slide while still held in attachment to thesocket 26. The rearward sliding is particularly advantageous when the foot is getting into or out of the shoe.

Thesockets 25 and 26 havemarginal flanges 25B and 26B, respectively, anchored by the coveringlayer 24. The coveringlayer 24 hasapertures 34 and 35 dimensioned to expose the full lengths of thesocket slots 25A and 25B, respectively, and to provide space forwardly of their open ends to facilitate the entry of the appropriate one of the studs. Ifapertures 34 and 35 were dimensioned so as to terminate flush with the open ends of theslots 25A and 26A, respectively, the attachment would be a non-detachable type. Detachability is a convenience, but not a necessary feature of the invention.

The shoe illustrated by FIGURES 4 and has a generally indicated sole 36 provided with aheel 37 and avamp 38. The sole 36 includes ashank tuck 39 and an additional layer ofshank tuck 40 and has asocket 41 in its shank area and a pair ofsockets 42 and 43 in itsheel area. Thesocket 41 has a forwardly opening,elongated slot 41A, thesocket 42 has a rearwardly openingelongated slot 42A, and thesocket 43 which is spaced'rearwardly of thesocket 42, has a forwardly openingslot 43A, also elongated.

A rear part upper assembly, see also FIGURE 9, consists of aheel section 44 having an inturnedbottom flange 45 divided at the rear by anotch 46. A length ofelastic tape 47 is attached to the undersurface of each front end of theflange 45 with thetape 47 extending forwardly and inwardly towards each other and secured in converging relationship, to aconnector 48. Abuckle 49, the details of which may best be seen in FIGURE 11, is dimensioned for entry into theslot 41A and includes ahook 50 extending downwardly and to each side- Thebuckle 49 is shown as having an integral crossed barredsection 51. A forwardly extending ribbon ortape 52 is attached to theconnector 48 and is threaded through thebuckle 49 to permit its effective length to be adjusted as desired and the ribbon or tape to be locked in. place. Other types of length-adjusting buckles may be used.-'A transverseelastic strip 45A interconnects theflanges 45 adjacent thenotch 46 and is provided with a downwardly disposedstud 53 for slidable entry into thesocket 43. The elastic strip facilitates pressing down the stud when attaching to a socket. It is not necessary, however, that the strip be elastic.

When thehook 50 is caught within thesocket 41 and thestud 53 has been entered in thesocket 43, the heelupper section 44 has a substantial range of sliding movement relatively to the heel area of the sole 36 rearwardly from its position of rest against the resilient opposition of theelastic tapes 47. In FIGURES 4 and 5, the attachingstud 53 is shown to be centrally located lengthwise in theslot 43A. This position of rest can be varied by adjusting the length oftape 52. The closed rear end of thesocket 43 serves, as would the closed portion of the sole at that rear end, to prevent the attaching stud or hook from being accidentally pushed out of the socket rearwardly by the foot.

Thesockets 41 and 42 are of the type illustrated in FIGURE 12, and their anchoring flanges, and the end wall of each socket extending downwardly below the plane of the anchoring flanges, are indicated by the suffix addition B and C, respectively. The socket 43.is of a similar type except that its end wall does not extend downwardly so far. Thestud 53 is shallow to avoid interference with heel nails. Each socket is seated in an aperture in thetuck 40 and is anchored by the engagement of thetuck 40 with its flanges, which are resting on thetuck 39. The aperture for thesocket 41 is indicated at 54 and that for thesocket 42 and 55. Thetuck 40 is provided with registeringapertures 56 and 57 and the apertures provide space to permit access to the open ends of each socket slot.

A cover member includes a section ofinelastic ma terial 58 secured to the fore part of the sole 36, aheel section 58A also of inelastic material, and an intermediate section ofelastic goring 59. The forward edge of theelastic section 59 is secured, as by cementing, to the undersurface of thesection 58 and the rearward edge of theelastic section 59 is secured to theheel section 58A. ATape 60 and atransverse strip 61 are interposed and anchored between the rear edge of theelastic section 59 and the forward edge of theheel section 58A. Thetape 60 is connected to thebuckle 62 which will not be further detailed as it is identical to that shown in FIGURE 11. In order to provide additional depth for the downwardly extending parts of thebuckles 51 and 62, thetuck 39 is provided withapertures 63 and 64 to accommodate them, and thetuck 40 has slightlylonger apertures 65 and 66 overlying theapertures 63 and 64, respectively. In addition, afiller layer 67, secured to the undersurface of thesection 59 has a tape-accommodatingaperture 68.

After theheel section 44 is attached the hook part of thebuckle 62 of the cover member is caught in thesocket 42, exposed within theheel section 44, after the effective length of thetape 60 has been suitably adjusted. This enables the lengthwise portion of theheel section 58A of the cover layer to be adjustable. When the adjustment results in an elastic tension strong enough to exert a flexing pull on the sole, it helps to minimize any upward strain by the foot on the heelupper section 44. Since thetape 60 at the rear attaching end of the cover member is narrow and is separated at the attaching position from the wider covering part, visibility and ease of attachability are facilitated, as is the use of a desirable type of narrow adjusting buckle and the attaining of a desirable amount of adjusting range. In addition, it enables thesocket 42 and thebuckle 62 to be depressed sufliciently to avoid being felt by the foot, without distorting the wider covering part.

In the embodiment of the invention illustrated by FIGURE 8, a fragment of the sole is indicated at 69 as is a fragment of avamp 70. The rear part upper assembly may be identical, except as hereinafter noted, to that shown in FIGURE 9 but its corresponding parts are distinguished by the suflix addition A.

The heelupper section 44A has astrap 71 pivotably connected to each of its sides bystuds 72 and eachstrap 71 includes an elastic section 71A connecting it to a tape 71B looped through abuckle 73 to enable its effective length to be adjusted as desired and having astud 74 at its other end which may be snapped into asocket 75 with which each side of thevamp 70 is provided or into a loop 76 attached to the sole 69, one on each side thereof. The position and construction of the elastic section as shown is not intended to limit the elastic section to the particular construction or position shown.

The rear upper assembly shown in FIGURE 10 is generally similar to that shown in FIGURE 9. The heel section 77 has a cut out bottom 78 providing a largecentral aperture 79. The rear portion of the bottom 78 is provided with a dependingstud 80. Anelastic section 81 is secured to the front of the bottom 78 centrally thereof and is connected to thebuckle 82 by a length oftape 83. Thebuckle 82 may be identical to thebuckle 49 so that it is not here detailed.

While the position of rest of the heel part upper section, in the embodiment of the invention illustrated by FIGURES 4 and 5 may be varied by varying the eflective length of thetape 52, in the case of the embodiment of the invention illustrated by FIGURES l and 2, the socket arrangement shown in FIGURE 13 may be used. In that arrangement, two alignedsockets 84 and 85 are employed with the open end of theslot 84A disposed towards but spaced from the open end of theslot 85A. The sockets are of the same type as thesockets 41 and 42, and their flanges and end walls are distinguished by the suflix additions B and C. Thesocket 85 is shown as having stop bars 86, which, when transferred into thesocket 84, provide means for changing the position of the rest of a heel upper section attached thereto. When the stop bars are used insocket 26 of FIGURE 1, theelastic sections 29 would enable theheel section 27 to have a more rearward position of rest.

In place of or in addition to the use of elastic fabric metal or plastic springs may be used for resiliency. For example, thesocket 87 shown in FIGURE 14 may be used in the embodiment of the invention illustrated by FIGURES 4 and 5 in place of thesocket 41. Thesocket 87 is of a type similar to thesockets 25, 41, and 42, in FIGURE 14, the slot, attaching flanges, and end wall are distinguished by the suffix additions A, B, and C as in the case of the other sockets. The socket '87 houses acompression spring 88 engageable by thehook 50.

The features herein pertaining to positional variability, slidability, and resilient resistance to rearward sliding are applicable even though details of construction may vary, and location of attachments to sole or upper may vary in any direction.

FIGURE shows a plan view and FIGURE 16 a sectioned view of a rearsole portion 89 with afront socket 90 and arear socket 91. Theflanges 92 ofsocket 90 and theflanges 93 ofsocket 91 are shown each held down byheel tuck 94. FIGURE 17 shows the sole portion '89 with a rear section of upper 95 attached thereto, and the rear part of acover section 96 with thetop layer 97 turned back to disclose the attachingpart 98; and FIGURE 18 shows theupper section 95 partially sectioned to disclose aconnection 99 between thebuckle 100 of attachingpart 98 of thecover section 96 and attachingpart 101 of theupper section 95. Theconnection 99 may be elastic or inelastic.

Added thicknesses are shown in rectangular form at 102 and 103 of FIGURES 15 and 17, although the shape may vary and they need not be confined to the particular area shown. The added thicknesses are preferably strips attached to the sole portion, although the manner of having added thickness in the area may vary. The purpose of the added thickness is to offset the top bulge created by theflanges 92 and 93, which permits a rocking or in stability of thesole portion 104 ofupper section 95. Added thickness could also be used in the rear adjacent toflange 105. The added thicknesses may be of resilient material such as foam or sponge rubber or polyurethane foam rising somewhat higher than the bulge resulting from the thickness of the flanges. Thus when pressed down when the rear section of upper is attached to the sole, this provides a desirable snugging effect.

It will be seen in FIGURES l7 and 18 that there is anaperture 106 insole portion 104 with a forward connectingwidth 107 between theside portions 108 and 109 of thesole portion 104 at the forward position where thesole portion 104 tapers thinner. In FIGURES l7 and 18, theribbon 110 of the attachingpart 98 is shown to depress the connecting width at the position in front of theaperture 106. This helps to resist sideways sliding. When the top 97 of the coveringpart 96 is in place it adds additional firmness against sliding.

Details may vary. For instance, while FIGURE 5 shows theribbon 60 of the attaching part as attached directly to the rear end of the elastic section, it may also be attached indirectly as by being attached to the covering section rearwardly of the elastic section.

From the foregoing it will be apparent that my invention provides footwear in which heel upper sections may have a range of sliding movement rearwardly from a position of rest with attendant advantages and that the invention also provides for a wide range of adjustments ensuring the full realization of those advantages.
