Definitions

  • girth is substantially the same as the girth of the wearer's foot, girth being the transverse circumference around the foot, typically measured at the ball waist and instep of the foot.
  • foot girth dimensions vary over a range of up to two inches for each length size while most popular price shoes now come in only one width per length, to allow marketing of the maximum number of styles with the minimum inventory, for end users who apparently value style and price over the virtues of fit and comfort.
  • the prior art has dealt mainly with visible means of girth adjustment such as laces, adjustment straps, and the like, most of which usually do not provide adjustment at the ball of the foot. Nor are such adjustment means useful in the many popular nonadjustable shoe styles, such as boots, slip-ons, loafers, womens' pumps, flats, and so forth.
  • the prior art has also neglected the children's field, where self-adjusting girth would allow a shoe to better fit the growing foot, aswell as facilitate the wearing of new slip-on styles that the child would not have to tie or otherwise adjust.
  • Adjustable girth footwear is not new, as shoes having this capability are disclosed, for example, in my U.S. Patent Nos. 3,404,468; 3,541,708 and 3,686,777. These prior shoes have a nonstretchable upper with longitudinally extending lower edge margins at least in the forepart of the shoe turned in toward one another and being free of the direct connection to the sole element.
  • At least one of those edge margins in the forepart of the shoe is connected by way of stretchable elastic sheet material extending under the wearer's foot to the middle of the sole element or to the other edge margin.
  • those edge margins are connected via the elastic material to the edges of the sole element. Both embodiments provide automatic adjustment of the shoe girth to suit the wearer's foot.
  • the elastic sheet material tends to lost its elasticity due to exposure to sun, ozone, ageing and wear so that the girth adjustment capability of such shoes tends to become degraded over time.
  • the elastic material being a relatively thin sheet of stretch nylon, located right at the sole of the shoe, soils easily and is prone to being cut, worn and punctured by contact with curbs, stones and other objects thereby allowing water to penetrate into the shoe.
  • such an exterior stretch material is quite expensive so that shoes of this type would tend not to be competitively priced.
  • Patent 3,442,031 Another technique for adjusting the girth of the shoe by adjusting the elevation of the foot within the shoe is disclosed in Patent 3,442,031.
  • a plural-layer auxiliary sole is inserted into the shoe between the insole and sock lining thereby reducing the amount of upper material that extends above the surface that supports the foot.
  • Each of the layers is of such a thickness as to change the girth of the shoe forepart by one standard width.
  • adjusting shoe girth in this fashion by elevating the foot within the shoe means that a person's feet may be supported at different heights. This is undesirable because it has been found that a foot height difference of as little as three sixteenths of an inch is sufficient to cause permanent injury to a person's back or legs.
  • a shoe capable of accommodating and fitting different foot widths.
  • the shoe comprises a shoe upper having side members; a foot support surface extending between lower edge margins of the shoe upper side members for supporting a foot inserted in the shoe; a sole assembly having a heel portion, a toe portion and a midportion between said heel and toe portions and comprising an insole assembly characterized in that: the shoe upper side members are deformable; the insole assembly comprises a platform member and a sole member having two side margins; said shoe upper side members being fixedly and non-elastically attached to the respective opposite side margins of the sole member, at least one side member of said sole member being disposed in such a manner so as to permit slidable movement relative to the platform member; and being laterally deformable at least at the midportion to permit vertical movement of the corresponding one of said shoe upper side members relative to said foot support surface so as to allow adjustment of the girth of the shoe to accommodate the girth of a foot supported on said support surface.
  • a shoe capable of accommodating different foot widths.
  • the shoe comprises a shoe upper; a sole element having a heel portion, a toe portion and a midportion between said heel and toe portions; a means for attaching said upper side portions to opposite sides of said sole element midportion; a foot support surface disposed inside the shoe in a position to contact the underside of a foot inserted into the shoe; characterized in that: the shoe upper has vertically movable side portions; said sole element being deformable at least at about its midportion and cooperating with at least one upper side portion to permit vertical movement of at least one of said upper side portions relative to said foot support surface so as to permit the adjustment of the girth of the shoe to accommodate the birth of a foot supported on said surface; and a means for permitting deformation of the sole element without causing any substantial change of the contour of the foot support surface or movement thereof.
  • Figs. 1-3 show a shoe 10 which includes a flexible upper 12 having a vamp 14 and a plug 16 joined by stitching to form a seam 18 around the forepart of the shoe, with a cuff 22 being provided around the top edge of the back part of the shoe upper 12.
  • the lower edge margins 14 a of vamp 14 are turned in as shown in Fig. 3 and preferably, although not necessarily, a laterally extensible sock lining or filler 24 extends between those margins 14 a .
  • the upper 12 is stitched, cemented or otherwise secured to a flexible unit sole assembly 26.
  • a floating insole 27 positioned above filler 24 and the shoe upper margins 14 a is a floating insole 27.
  • the insole extends the entire interior length and width of the shoe, but is not attached to the shoe upper.
  • Unit sole assembly 26 comprises a foundation or platform 28 which includes a thin, relatively flexible upper layer 28 a made of polypropylene or the like and a relatively flexible lower layer 28 b consisting, for example, of conventional E.V.A. material.
  • Snugly surrounding platform 28 is a flexible molded rubber or plastic unit sole 32.
  • the unit sole has a substantially flat bottom surface 32 a , a pair of gently rounded side walls 32 b and an in-turned marginal top surface 32 c that extends all around the unit sole assembly 26.
  • a peripheral recess 33 is provided in the upper surface of platform section 28 a to provide clearance for the unit sole top surface 32 c .
  • the in-turned marginal top surface 32 c of the unit sole is secured the in-turned edge margin 14 a of the shoe upper by stitching 36.
  • the shoe upper 12 and unit sole 32 are made of materials which can be cemented together either directly or by way of intervening strips of sheet material (not shown), cement may be used to secure those parts together.
  • the connections between the upper marginal edges 14 a and the unit sole top surface 32 c at least at the forepart of the shoe particularly in the ball area thereof are non-stretchable, non-elastic connections that do not create undesirable gaping between the upper 12 and the sole assembly 26 at the sides of the shoe.
  • those stitches or connections 36 are spaced inward from the side edges of the unit sole assembly 26 at least in the forepart of the shoe, a distance of preferably approximately one centimeter, for reasons that will become apparent.
  • unit sole assembly 26 is deformable laterally in that top surface 32 c of sole element 32 on at least one side, and preferably both sides, of sole assembly 26 is free to slide laterally relative to platform section 28 a between a minimum girth position illustrated in Fig. 3 and an enlarged girth position shown in Fig. 4.
  • the outward movements of the element top surface 32 c achieve a rolling action with the unit sole element side walls 32 b as shown by the arrows X in Fig. 4 so that there is little apparent change in the outward appearance of the unit sole assembly 26.
  • Such lateral motion of the sole element top surface 32 c also allows upward movements of the lower side margins 14 b of vamp 14 relative to the innersole 27 that contacts and, along with assembly 26, supports the wearer's foot. These movements, shown by the arrows X in Fig. 4, can be considerable and can increase the girth of the shoe by as much as four standard shoe width sizes, as from women's size AAA to B or from men's size C to EE. Conversely, inward sliding movements of the unit sole's top surface 32 c produces corresponding rolling actions in the opposite directions, of the unit sole side walls 32 b and downward movements of the side margins of the vamp attached to the unit sole element.
  • the filler panel 24 does not necessarily contribute to any significant extent to the girth adjustment capability of the shoe 10.
  • the means comprises a pair of thin elongated stiffener plates 42 positioned at opposite sides of sole element top wall 32 c in the waist area of the shoe. Plates 42 extend along, and follow the contours of, the marginal wall 32 c .
  • Each plate 42 has an integral laterally extending tab 42 a that extends towards the longitudinal centerline of the shoe.
  • a thin circular cam plate 46 Positioned below plates 42 and their tabs 42 a is a thin circular cam plate 46, which has a central pin or axle 48 which is rotatably mounted to platform section 28 a .
  • the upper end of the pin 48 is accessible from inside the shoe through an aperture 50 (Fig. 2) in the filler panel 24 and that end is preferably slotted to facilitate turning the cam plate 46 by a coin or screwdriver.
  • access to the opposite end of the axle may be provided at the underside of the shoe.
  • a pair of follower pins 52 project from tabs 42 a and engage in oppositely directed spiral cam slots 54 in cam plate 46.
  • cam plate 46 When cam plate 46 is rotated in one direction, i.e. counterclockwise in Fig. 2, those pin-in-slot engagements cause the stiffener plates 42 to be spread apart so that the opposite sides of the unit sole element top wall 32 c are moved apart to their positions of maximum girth adjustment shown in Figs. 4.
  • the cam plate 46 is rotated in the opposite direction, i.e. clockwise, the camming action of the plate 46 draws the two stiffener plates 42 toward one another to their minimum girth adjustment positions shown in Fig. 3.
  • Conventional detent means may be provided to retain plate 46 in its various positions of adjustment.
  • the upper wall 32 c of the sole element 32 is sufficiently stiff in the lengthwise direction for there to be minimal relative longitudinal motion of the stiffener plates 42 when the cam plate 46 is turned.
  • transverse slots 56 FIG. 5
  • registering grooves 57 in the top of section 28 b to receive pins 52 and limit those movements to lateral ones.
  • top wall 32 c moves correspondingly, the lateral motion of the wall being proportional along the shoe so as not to unduly "crowd" the wearer's foot at the different points along its length. Since there is minimal or no movement of the sole element top surface 32 c at the toe and heel portions of the shoe, direct connections may be made between the sole element top wall 32 c and the platform 28 at those locations, as indicated at 58 in Figs. 2.
  • the foot is inserted into the shoe pre-set at its widest girth as in Figs. 2 and 4. If the shoe at that setting is too wide, the cam plate 46 is turned clockwise as necessary thereby drawing the stiffener plates 42 and the opposite sides of the sole element top surface 32 c closer together. This results in vertically downward components of motion of the lower side margins of 14 a vamp 14 relative to the innersole 27 and the underlying platform 28 which support the wearer's foot so that the upper comfortably fits the girth of the foot.
  • the girth of the shoe 10 can be adjusted to provide an optimal fit to that wearer's foot without affecting the height of the foot within the shoe or above the ground.
  • Figs. 6 - 8 illustrate a shoe 60 similar to shoe 10 having a somewhat different unit sole assembly which allows automatic girth adjustment.
  • the shoe upper 12 is substantially the same as the one in shoe 10.
  • the in-turned lower edge margins 12 a of the upper 12 are connected non-elastically to a unit sole assembly shown generally at 62.
  • Assembly 62 includes a platform 64 made of flexible, resilient, somewhat compressible material such as cellular E.V.A. plastic. While the undersurface 64 a of platform 64 is generally flat, between heel breast and toe the platform undersurface is provided with upwardly curved side margins 64 b which extend to the substantially vertical side edges 64 c of the platform.
  • a marginal recess 65 is present in the upper surface of platform 64 all around the perimeter of the platform to provide clearance for the margins of the unit sole assembly 62 and of the shoe upper 12, to which said unit sole margins are attached.
  • unit sole assembly 62 includes a flexible, resilient unit sole element 66 which engages snugly around platform 64.
  • the sole element has a bottom surface 66 a , a side wall 66 b and an in-turned marginal top surface 66 c which underlies the edge margin 12 a of the shoe upper.
  • the marginal top surface 66 c of unit sole element 66 is secured to the marginal edge 12 a of the shoe upper 12 by stitching 68 or other suitable means.
  • a stiffener frame 72 secured to the top surface 66 c at the underside thereof is a stiffener frame 72 which preferably extends all around the shoe.
  • the stiffener frame 72 is thin, (e.g. .040 inch) and somewhat flexible and made of a strong, crack-resistant material such as polypropylene.
  • the stiffener frame has a series of slits and/or notches 74 distributed around the frame creating a similar distribution of living hinges 76 which allow the sides of the frame 72 to flex laterally, i.e. toward and away from one another.
  • the slits or notches 74 and hinges 76 are strategically placed to allow controlled transverse movements of the different lengthwise segments of the frame to achieve proportional motion of the frame sides along the shoe to allow not only for infinitely variable and continual adjustments for the girth of each foot, but also for the different relationships between ball and instep girths of that foot.
  • the frame functions to control girth adjustment proportions so that at any particular girth adjustment, the shoe has girth measurements at least along the midportion of the shoe similar to those of a conventional fixed girth shoe of the nearest fixed girth.
  • the lower edge 66 d of the sole element 66 has a relatively sharp corner.
  • the upper edge 66 e of that element is rounded.
  • unit sole assembly 62 is biased to this minimum girth condition by at least one spring 82 stretched between a pair of rivets or pins 84 mounted to opposite sides of stiffener frame 72, preferably in the waist area of the shoe. If needed, a shallow transverse slot or channel 86 may be formed in the top wall of platform 64 to provide clearance for the the spring.
  • the shoe at its minimum girth adjustment shown in Fig. 8 may be lasted to fit, for example, a foot having a men's size C width.
  • Sufficient compliance is built into the sock lining or filler panel 24 to accommodate the lateral movements of the upper edge margins 12 a and, since the innersole 27 has no direct connection to the shoe upper, that member does not interfere with the accommodation of the shoe to that larger girth foot.
  • the marginal top surface 66 c of sole unit element 66 is prevented from pulling out of recess 65 by the stretch limit of the panel 24 or other suitable limiting member that may be incorporated into the shoe.
  • Figs. 6 to 8 may be modified to provide a manual adjustment of shoe girth simply by substituting for the spring 82, means for manually controlling the spacing between the opposite sides of stiffer frame 72 such as the camming mechanism present in shoe 10 described above.
  • the invention can also be incorporated into shoes of various styles and with various other sole assembly constructions.
  • Fig. 9 illustrates the ball area cross section of a loafer type of shoe 90 wherein the connection of the shoe upper to the sole element is by way of a thin, flexible, preferably integrally molded, inwardly extending marginal top flap 102, extending from the top edge of the sole element.
  • Shoe 90 has an upper 12 which is essentially the same as that of shoes 10 and 60 and a sole assembly 92 that is somewhat different from the other sole embodiments in that it includes a preferably molded unit sole element 94.
  • the unit sole element is molded or otherwise formed with a marginal recess 96 extending around its upper surface which provides a seat for the marginal top flap 102, as well as for a stiffener frame 98 which is similar to stiffener frame 72 described above in connection with Figs. 6 - 8.
  • Flap 102 is folded inward over frame 98 and secured between the upper edge margin 12 a and stiffener frame 98 by stitching or cement 104 which is spaced inward from the sides of sole element 94.
  • the opposite sides of stiffener frame 98 and of flap 102 are movable laterally in recess 96 toward and away from one another just as described above in connection with shoe 60 in Figs. 6 - 8 between positions of minimum girth adjustment shown in solid lines in Fig. 9 and positions of maximum girth adjustment shown in phantom in that figure.
  • shoe 90 can provide automatic girth adjustment.
  • a manual girth adjustment mechanism similar to the one in shoe 10 may be incorporated into shoe 90 so that the girth of that shoe can be adjusted manually to suit the particular wearer's foot.
  • Fig. 10 illustrates the ball area cross section of yet another shoe 110 incorporating my invention.
  • This shoe shown in a girth enlarged condition, has a shoe upper 12 which is essentially the same as the ones in the other shoe constructions described above and a unit sole assembly 112 which includes a platform 114.
  • the platform has a generally flat bottom surface 114 a and opposite sides 114 b , at least in the midportion of the shoe, which slant upwardly-inwardly, and finally, a marginal recess 115 which extends all around said platform.
  • Wrapped around platform 114 is a unit sole element 116 that is made of a rugged, flexible, non-extensible material such as one of the many unit sole materials now in use.
  • Sole element 116 is secured to platform 114 and to a stiffener frame 122 positioned in recess 115 by means of a flexible, non-stretchable, distortion preventing means such as binding strip 118. More particularly, a lower edge margin 118 a of strip 118 is sandwiched between platform surface 114 a and the upper surface of sole element 116, with cement being placed on both sides of the strip margin so that the strip margin becomes firmly secured between the platform and the sole element. The upper edge margin 118 b of strip 118 is wrapped around the sides of platform 114 and turned inwardly and cemented or otherwise fastened to the top surface of stiffener frame 122, positioned on platform recess 115.
  • This frame may be identical to frame 72 described above.
  • edge margins of sole element 116 extend up around the sides of platform 114 and strip 118 and are turned inward on top of the strip margin 118 b thereby forming the rounded sidewall 116 b and in-turned top surface 116 c of the sole element. That top surface 116 c is then preferably cemented or otherwise secured at 126 between the shoe upper edge margins 12 a and the strip margin 118 b .
  • stiffener frame 122 and of the sole element top wall 116 c are slidable laterally in recess 115 between a position of maximum girth adjustment shown in solid lines in Fig. 10 and a position of minimum girth adjustment indicated in phantom in that figure. In the latter position the opposite sides of the stiffener frame 122 abut the inner wall of recess 115 and the strip sides 118 c lie flush against the bevelled side wall 114 b of platform 114 as shown in phantom in Fig. 10.
  • the sole assembly may be urged toward this minimum adjustment condition by a spring similar to spring 82 stretched between the opposite sides of stiffener frame 122 to provide automatic girth adjustment.
  • a camming mechanism similar to the one in shoe 10 may be incorporated into the sole assembly if a manual girth adjustment capability is desired. If the foot inserted into shoe 110 calls for a wider girth than the minimum girth of the shoe, the opposite sides of the stiffener frame 122 must be spread apart as described above in connection with the other shoe embodiments.
  • the distortion preventing means that is, the inextensible strip 118, prevent the opposite sides of the stiffener member 122 and the sole element edge margins 116 c from sliding out of recess 115 beyond their positions shown in solid lines in Fig. 10. Just as important, the strip 118 prevents the unit sole assembly 112 from having excessive unsightly differences in apparent side thickness along its length.
  • the distortion preventing means could also comprise parallel monofilaments or the like, disposed between the stiffener member 22 and the lower edge of the platform 114 and/or sole element 116.
  • shoe 132 has an upper 134 attached to a unit sole assembly 136.
  • the sole assembly comprises an interior platform or foundation member 138 made of a suitable flexible material such as cellular E.V.A. plastic. Wrapped around the platform member is a preferably molded unit sole element 142 similar to unit sole element 116 described above in connection with Fig. 10.
  • the unit sole element has a relatively flat bottom surface 142 a , upturned side walls 142 b and an in-turned marginal top surface 142 c which is secured by cement or stitching at 144 to the in-turned lower edge margin 134 a of the shoe upper 134.
  • a marginal recess 146 is provided in the upper surface of platform member 138 to accommodate the marginal connections between the shoe upper and the sole element.
  • Assembly 148 extends the full length and width of the last bottom of the shoe and comprises a thin flexible support member 152 made of polypropylene or like material. Covering that member is a lining 154 of "Cambrelle" brand or similar fabric. Also positioned under the support member 152 is a stiffener frame 156 similar to frame 72 described above and a spring (not shown) similar to spring 82 is stretched between the opposite sides of frame 156.
  • the lining 154 is larger than support member 152 and its edge margin 154 a is wrapped around the edge of support member 152 and turned inward under stiffener frame 156 where is secured by cement or other similar means as indicated by the extensions of the cement or stitching lines 144.
  • the insole assembly 148 would be assembled outside the shoe and then cemented in place.
  • Shoe 132 when off the foot remains at its position of minimum girth adjustment wherein the edges of the shoe upper margin 134 a and sole element margin 142 c , as well as stiffener frame 156, abut the inner wall of recess 146, and the side walls 142 b of sole element 142 engage snugly around the sides of platform member 138. If the shoe is worn on a foot requiring a girth larger than the shoe's minimum girth, the opposite sides of the sole element's top surface 142 c slide outwardly while their outer edges and side walls 142 b roll downwardly as indicated by the arrows D in Fig. 11 in the same manner as the similar sole elements in the Figs. 3 and 10 shoe constructions described above.
  • That transverse sliding and rolling action allows concomitant vertical movements of the shoe upper side margins 134 b , as shown by the arrows E in Fig. 11, to increase the amount of upper material above the insole assembly 148 by just the right amount to accommodate that wider foot.
  • the lining 154 unfolds or unrolls around the edge of support member 152 so that the lining still covers the bottom of the shoe interior even when the shoe is in its position of maximum girth adjustment shown in Fig. 11.
  • the transverse sliding and rolling action of the sides of the insole is similar to that of the unit soles's sides as they adjust together to accommodate the girth of the wearer's foot. It should be noted that this type of insole construction could be used in most of the other embodiments disclosed in this application.
  • Figs. 13 - 33 relate to a means in a shoe for deforming the sole element in the forepart of the shoe relative to the shoe support surface which contacts the underside of the wearer's foot to permit upward movements of at least one side margin of the upper to accommodate the girth of the wearer's foot.
  • shoe 200 includes a flexible upper 222 having a vamp 223 and a plug 224 which are typically joined by stitching to form a seam 226 around the forepart of the shoe 200, with a cuff 228 being provided around the top edge of the back part of the shoe upper.
  • Shoe 200 also has a sock lining 236 stitched to the lowermost marginal edges of upper 222.
  • the upper is, in turn, stitched or otherwise secured to a flexible sole element 230.
  • the upper is stitched to the upstanding walls 232 of a cupmolded sole element or unit sole at the uppermost edges thereof.
  • footbed assembly 234 Positioned in shoe 200 above the sock lining 236 is a footbed assembly 234.
  • This assembly includes a relatively stiff footbed or insert 240 consisting of a relatively thick slab of high density polypropylene or like material.
  • a sheet or layer 238 of a thin tough flexible material such as high density polyethylene.
  • a conforming innersole 246 extending the full width of the shoe and from the toe to the heel thereof may be disposed on the upper surface of footbed 240.
  • the upper surface of the footbed assembly 234 may be contoured orthopedically as shown to be somewhat higher on the inside heel breast and arch area as compared with the corresponding outside area and to have a somewhat concave curvature in the heel portion thereof to comfortably accommodate and center the heel of the wearer's foot. It may also have contours forward of the heel area to better support and position the foot in the shoe in that area.
  • the underside of footbed 240 or insert is contoured at one and preferably both bottom side edge margins 248 thereof to allow limited controlled vertical deformation of the side edge margins 230 a of the sole element 230 in the critical fitting area toeward of the heel breastline, i.e. the line defined by the usual position of the forward face of a usual heel element.
  • the underside of footbed 240 is flat in the heel area of the bed as shown in Fig. 17, it has a chamfer on at least one and preferably both sides thereof each of which extends longitudinally from the heel breast forward towards the toe portion of the footbed as best seen in Fig. 16.
  • the footbed also has a more extensive arcuate bottom chamber between ball and instep, to accommodate a spring to be described.
  • the contours or profiles of those chamfers may be different from one another and they both vary along the length of the footbed 240 as shown in Figs. 17 - 19 leaving gaps of varying widths between the footbed edge margins 248 and the sheet or layer 238 at the underside of bed 240.
  • those gaps are filled with compressible resilient foam materials 250 to exclude foreign material from those spaces as well as to help urge the shoe continually to its minimum girth adjustment.
  • a series of transverse grooves 260 may be included in the underside of footbed 240 in the ball area thereof. These grooves facilitate bending of assembly 234 together with shoe 200 when the wearer of the shoe is walking. If desired, these grooves may also be filled with compressible resilient foam material to exclude dirt therefrom.
  • footbed assembly 234 is positioned in shoe 200 as shown in Figs. 13 and 14.
  • that assembly is not attached physically either to the shoe upper 222 including sock lining 236 or to the sole element 230.
  • Sole element 230, or at least the edge margins 230 a thereof underlying the contoured edge margins 248 of footbed 240, are flexible and upwardly deformable allowing an upward flexing of the sole element edge margins 230 a toward footbed edge margins 248 from a minimum girth condition shown in Fig. 14 wherein sole element 230 is flat, to a condition depicted in Fig. 15 wherein the edge margins of sole element 230 are deformed or deflected upwards to a maximum girth condition.
  • edge margins 230 a are greater than the slight upward curling that sometimes occurs at the edge margins of an ordinary shoe sole due to normal flexing of the shoe when worn.
  • This deformation of sole elements 230 results in an upward component of motion of the side margins of vamp 223 and sole sidewalls 232, relative to the surface of the innersole 246 which contacts the underside of the wearer's foot.
  • These movements shown by the arrows in Fig. 15, are appreciable and can increase the girth of the shoe by as much as four standard shoe width sized, as from women's size AAA to B or from men's size C to EE.
  • the preferred biasing means include a generally trapezoidal leaf spring 254.
  • the spring fits into transverse channels 256 (Figs. 13 and 19) disposed in the underside of footbed 240.
  • the spring is formed so that in its natural unstressed state, it has the shape of an arch.
  • spring 254 is incorporated into the footbed assembly 234, it is sandwiched between footbed 240 and sheet 238 and flattened to some extent as shown in Fig. 19.
  • a mechanism may be incorporated into the footbed assembly for controlling that adjustment manually as depicted in Figs. 20 and 21.
  • a drum 255 is rotatably mounted in footbed or insert 240 and spring 254 at the center of those parts.
  • the lower end of drum 255 is accessible and carriers a slot 259 which permits the drum to be rotated manually by a screwdriver or the like through the bottom of the footbed assembly 234.
  • a pair of cables 257A and 257B have corresponding first ends wound in opposite directions around the drum. The opposite end segments of the cables pass through grommets 258 mounted in footbed 240 adjacent to the side edges thereof.
  • Figs. 22 and 23 illustrate a shoe 500 whose girth can be set manually by positively controlling the spacing between the edge margins of the footbed and the edge margins of the sole element.
  • This shoe includes an upper shown generally at 502 with a vamp 506 having a continuous portion 524 extending under the foot and attached by stitching 507 or the like to a flexible resilient sole element 508.
  • a footbed assembly 510 Located inside the shoe is a footbed assembly 510 composed of a footbed 512 which may be provided with a sock lining 514 at its upper surface.
  • the footbed 512 is similar to footbed 240 described above in that it extends the entire length of the shoe and has undersurface edge margins 516 which may be similar to the margins 248 in the Fig. 13 shoe, although without the springaccommodating transverse channels 56 therein.
  • Each shim strip 520 is co-extensive with the edge margin of footbed 512 and it is generally tapered or wedge-shaped in cross section, as best seen in Fig. 22.
  • the edge margins 516 are preferably also contoured along their lengths.
  • sole element 508 is maintained in a substantially flat undeformed condition as shown in Fig. 22, with the shoe adjusted thereby for minimum girth or shoe width size.
  • one or more of the shim strips 520 is removed from at least one and preferably both sides of the shoe thereby providing clearance between the footbed edge margins 516 and the underlying vamp margins. Accordingly, the edge margins 508 a of the sole element are permitted to deform or deflect upwardly toward the footbed margins 516. This allows concomitant upward movements of the lower side margins of the vamp 506 relative to innersole 514 on which the foot is supported as shown by arrows S in Fig. 23 thereby increasing the girth of the shoe to accommodate that larger width foot.
  • the sole element 508, being resilient, can exert a gentle downward pull on the vamp to assure that the shoe fits snugly on the foot.
  • the shim strips 520 may be adhered to the underside of the footbed 512 in which case they may be stripped away when it is necessary to increase the size of the shoe.
  • the number of strips present at each side of the shoe or in the two shoes of a pair at any given time may be the same or different depending upon the needs and desires of the particular wearer. Since the foot is always primarily supported by the platform assembly, the number of strips in the shoe has no effect on the elevation of the foot within the shoe or above the ground. It is also quite feasible to form shim strips of varying wedge angles and profiles as the edge margins of separate insole members arranged to be positioned under the footbed assembly 510. In both cases, the shim strips positively control the upward deformation or displacement of the edge margins of the sole element and thus the upward movements of the vamp side margins to accommodate the shoe to the particular wearer's foot girth.
  • Figs. 24 to 27 illustrate a shoe construction somewhat similar to the one just described and which provides for automatic rather than manual adjustment of the shoe girth.
  • Shoe 549 has an upper 560 whose vamp 562 also extends under the wearer's foot and is attached directly to a flexible sole element 569 by stitching, cement or other suitable means.
  • a footbed assembly shown generally at 550 is positioned inside the shoe. Like assembly 510, it includes a relatively stiff footbed 552 and a thin sock lining 576 covering the upper surface of that member. Also, the underside of footbed 552 has edge margins 554 which are contoured in more or less the same manner as the similar footbed described above in connection with the Figs. 13 and 22 shoes.
  • the means for adjusting the shoe girth is not incorporated into the footbed assembly 550. Rather, it is present in the sole element 569. More particularly, a transverse pocket or recess 574 is formed in the sole element 569 in the ball area of that element. Positioned in recess 574 is a spring assembly 558. As best seen in Figs. 25A and 25B, spring assembly 558 comprises a relatively long thin highly flexible generally trapezoidal spring member 570 and a shorter thicker stiffer similarly shaped spring member 572. Spring member 570 in its unstressed state is bowed or arched as shown in phantom in Fig. 25B, while spring member 572 is normally flat.
  • spring member 572 When spring member 572 is positioned under spring member 570 and the two springs are secured together by rivets 573 as shown, the spring member 570 is forced by the its stiffer mate to assume a more or less straight flat configuration as shown in solid lines in Fig. 25B.
  • spring member 570 is pre-loaded and designed to have a favorable spring rate, e.g. of about 0.6 lb. per longitudinal inch of spring dimension, when its ends are deflected upward only slightly from their flat solid line positions, e.g. to the upper position shown in phantom in Fig. 25B.
  • a spring so "preloaded” will therefore have a spring rate such that the spring and with it, the sole and the upper elements exert comfortable gentle pressure on those feet within its design girth range.
  • both the spring assembly and the sole element remain essentially flat so that there is appreciable clearance between the contoured edge margins 554 of footbed 552 and the underlying vamp margins on sole margins 569 a .
  • the shoe depicted in Fig. 24 reposes a condition of minimum girth so that it may fit, for example, a men's size C foot width.
  • the sole edge margins 569 a are free to flex upwards relative to the edge margins 554 of footbed 552 and in opposition to the urging of spring member 570. This permits an upward displacement of the lower side margins of vamp 562 in the direction of arrows T in Fig. 26 by just the right amount to accommodate the increased girth of that larger foot, all as described above in connection with the Figs. 13 and 22 shoes.
  • a spring assembly similar to assembly 558 may be incorporated into the shoe insole rather than outsole element.
  • Fig. 27 to 30 illustrate still another mechanism for adjusting shoe girth manually.
  • the shoe comprises and upper 630 including a vamp 634 having in-turned lower edge margins cemented, stitched or otherwise secured to an outsole element 632.
  • a footbed assembly 600 is positioned in the shoe. This assembly comprises a footbed 602 having contoured side margins 604 on the underside thereof, as described above for the other similar footbeds.
  • a pair of transversely movable, relatively rigid struts 606 are positioned in a recess 607 in the underside of member 602. These are pivotally connected to that member by a pair of heel pivot pins 608 and a pair of toe pivot pins 610 so that the struts extend along the forepart of footbed 602.
  • Each strut 606 has a transverse cut 612 midway along its length, terminating in a "living" hinge 614 adjacent to its inner edge as shown in Fig. 27 which permits the struts 606 to bend or flex laterally outward as indicated by the arrows "O" in that figure.
  • a rotatable cam plate 616 having a pair of spiral cam slots 618 cut therein, is positioned in a clearance space in the underside of the footbed 602 above struts 606 in the waist area of the shoe as best seen in Figs. 27 and 28.
  • cam follower pins 620 mounted to struts 606 are in following engagement with the two cam slots 618 in the cam plate 616.
  • the cam plate 616 is secured to a post 622 rotatively mounted to the footbed 602. As shown in Fig. 28, a slot 624 formed in the upper end of post 622 is accessible through an aperture in sock lining 626 on footbed 602 in order to rotate the cam plate 616.
  • the toe pivot pins 610 extend through slightly elongated openings 628 in the toe end of each of the struts 606. After the footbed assembly 600 is placed in a shoe, as shown in Figs. 28 and 29, these elongated openings 628 allow longitudinal movements of the forward ends of the struts 606 with respect to the platform 602 as would occur during the walking cycle.
  • the footbed 602 of assembly 600 is wrapped about its bottom and side edges by a thin flexible sheet 636 of polypropylene or like material, which may be lasted over the marginal upper surface of the footbed 602 as shown.
  • the sock lining 626 is then positioned on member 602 with an opening in the insole 626 in alignment with the upper end of the post 622.
  • This position of the struts 606 may allow the shoe to accommodate say, a men's "EE" foot width.
  • the struts 606 provide a stiff shield against any appreciable upward flexing of the sole element edge margins 632 a so that minimal or no upward movements of the shoe upper side margins occur.
  • This minimum girth setting of the cam plate may accommodate the shoe to a foot of, say, men's size C width with intermediate settings of the cam plate 616 achieving infinitely variable shoe girth values within the designed girth range limits of the shoe, which, in this case, are men's C and EE.
  • Figs. 31 to 33 illustrate still another shoe construction that provides automatic girth adjustment by deforming the shoe sole element.
  • the sole element is simply expanded laterally or transversely preferably at least one-eighth inch and, usually up to, as much as three-eighths inch depending on the amount of girth adjustment required.
  • This shoe like the others, includes an upper 708 having a vamp 712 with in-turned lower edge margins 714 secured by stitching 716 or the like to the side edge margins of a sole element 700.
  • the securement of the camp to the sole element at 716 would preferably be set in approximately one centimeter from the corresponding side edge of the sole element 700.
  • Attached to the opposite edges of vamp margins 714 is a filler sheet 717 of laterally deformable material.
  • a floating insole 718 is provided inside the shoe.
  • the top and bottom faces of the sole element Prior to attaching sole element 700 to the upper, the top and bottom faces of the sole element are slitted or micro-siped to provide a series of longitudinal slits 704 extending partially through the sole element, with the slits in the two faces being staggered as shown. These slits 704 are confined to the forepart of the shoe sole element 700.
  • the bottom face of the sole element 700 may also be provided with a series of shallow transverse grooves 706. These transverse grooves do not contribute to the invention and may be included simply for traction or aesthetic reasons.
  • Sole element 700 by virtue of slits 704, is elastically deformable or expansible laterally between a minimum width condition shown in Fig. 32 to a maximum width condition illustrated in Fig. 33.
  • This expanding deformation of the sole element outward produces a concomitant upward motion of the side margins of the vamp 712 as shown by the arrows z in Fig. 33.
  • These upward movements of the vamp relative to the insole 718 that contacts the underside of the foot increase the girth of that shoe so that the shoe can accept a foot of corresponding increased girth, all as described above in connection with the other shoe embodiments.
  • the natural resilience of the stretched sole element 200 tends to urge the sides of the upper inwardly and downwardly thus assuring a snug fit on the wearer's foot.
  • FIG. 33 Other laterally extensible sole constructions can be envisioned, such as one consisting of a molded rubber matrix or wavy pattern filled with foam rubber, which will extend at least oneeighth inch to allow the requisite girth adjustment.
  • the sole can be formed initially with open V-shaped slits or grooves as in Fig. 33 in which case the sole would be compressible laterally one-eighth inch or more to the condition shown in Fig. 32. This compression would allow downward movements of the side margins of vamp 712 to achieve girth adjustment in the opposite sense.
  • the specific shoe girth would be adjusted manually, say, by a drum and cable mechanism similar to the one in Fig. 20 that controls the spacing of the edge margins of the sole element.
