Definitions

  • insole inserts A commercially successful approach to girth adjustment by varying the thickness of insole inserts is currently being used in shoes sold by Toddler's University, of Westport, CT, and others. In this approach, usually three separate insoles of differing thicknesses are provided with each shoe for insertion therein.
  • the inserts may be used to adjust the girth of the shoe since each insert occupies a different volume in the shoe, particularly in the critical fitting regions of ball waist and instep.
  • the inserts are designed and designated as N, M and W, (i.e. narrow, medium and wide) and usually represent three consecutive standard width increments.
  • the above approach has been only modestly successful. It has certain inherent limitations to which the improvements of the present invention are addressed.
  • the above approach requires the use of multiple inserts which must be removed and exchanged by the wearer to achieve girth adjustment.
  • the insert arrangement only allows for adjustment to certain predetermined girths and does not permit the preferred infinitely variable girth adjustment, nor does it permit such girth adjustment while the shoe is on the foot for maximum ease and accuracy.
  • U.S.S.N. 07/441,978, filed 11/28/89 of this inventor discloses a ramp system that adjusts the shoe girth by insole edge thickness variation only, which may have limited market acceptance due to the market's general preference for a conventional approach, whereby the central portions of the insole are transversely flat under the foot and of constant height above the walking surface.
  • Another object is to provide girth adjustment means which is adjustable while on the wearer's foot.
  • the present invention is directed to a shoe having an insole assembly disposed therein, which contains a means to vary the thickness of the assembly at least at the mid-portion of the shoe.
  • the thickness varying means is an integral part of the assembly rather than removable elements or inserts which must be exchanged to effect thickness adjustment.
  • the insole assembly extends substantially across the width of the shoe at least at the mid-portion and preferably along the entire length of the shoe cavity. As the thickness is varied, the fitting height between the top of the insole assembly and the inner surface of the upper within the shoe cavity decreases particularly in the mid-portion of the shoe, thereby decreasing the girth of the shoe in this critical fitting area.
  • the means to vary the thickness of the insole assembly generally comprises at least one and preferably two movable members such as movable ramps which are disposed in a portion of the insole assembly.
  • the movable members extend across substan ⁇ tially the entire width of the insole assembly.
  • the movable members may be moved forward toward the toe of the shoe, thereby increasing the thickness of the assembly in the midportion of the shoe across substantially the entire width of the shoe cavity. Since the movable members extend across the width of the assembly the transverse contour of the assembly remains substantially flat no matter the position of the movable members.
  • any suitable mechanism may be employed to move the movable members, it is presently preferred to employ a cable mechanism comprising one or more cables connected to the movable members and a rotatable member which is also connected to the cables. Rotation of the rotatable member moves the movable members forward or rearward depending on the direction it is turned.
  • the rotatable member is preferably disposed in the heel of the shoe and extends through the heel at its breast so that adjustment can be made by the wearer without removing the insole assembly from the shoe or the shoe from the foot.
  • the insole assembly generally comprises an expandable bladder which may be adjusted to increase and decrease the fitting height.
  • a removable insole assembly may be employed which requires removal of the assembly to effect adjustment.
  • Fig. 1 is a side-elevational cross-sectional view of a shoe of the present invention adjusted to its maximum girth.
  • Fig. 2 is a plan view of the insole assembly and bottom details of the shoe of Fig. 1, taken along line 2-2 thereof.
  • Fig. 3 is a side elevational cross-sectional view of a shoe of the present invention adjusted to its minimum girth.
  • Fig. 4 is a plan view of the insole assembly and bottom details of the shoe of Fig. 3 taken along line 4-4 thereof.
  • Fig. 5 is a transverse cross-sectional view of the shoe of Fig. 1, taken on line 5-5 thereof.
  • Fig. 6 is a transverse cross-sectional view of the shoe of Fig. 3, taken on line 6-6 thereof.
  • Fig. 7 is a plan view of a removable insole assembly of this invention.
  • Fig. 8 is a transverse cross-sectional view of the insole assembly of Fig. 7, taken at the heel portion thereof on line 8-8.
  • Fig. 9 is a transverse cross-sectional view of the insole assembly of Fig. 7, taken in the ball area thereof on line 9-9.
  • Fig. 10 is a side sectional view of the insole assembly of Fig. 1 , taken on line 10-10 thereof.
  • Fig. 11 is a side-elevational cross-sectional view of another shoe of the present invention.
  • Fig. 12 is a plan view of the insole assembly of the shoe of Fig. 11.
  • shoe 20 generally comprises an upper 22 having a plug 26 attached at a sewn seam 28 to a vamp 30.
  • the seam 28 extends substantially around the forepart and mid-portion of the upper 22 which in turn is secured by cement adhesive and/or stitching 32 or by other conventional means to a unitsole 34.
  • the upper 22 may be made of any of the conventional upper materials, including leather, fabric and the like.
  • Unitsole 34 can be molded of conventional rubber and/or plastic materials, or can alternatively be a conventional assembly of molded and/or sheet materials.
  • the insole assembly 36 is disposed along the bottom of the shoe cavity 24 adjacent the top surface of the bottom of vamp 30 and unitsole 34.
  • the insole assembly extends substantially along the entire length of the shoe cavity from the heel portion H, through the midportion M and toe portion T, and across substantially the entire width of the cavity 24. While this is the preferred design, the insole assembly need not extend across substantially the entire inside width of the shoe at the toe and heel portions but merely in the mid-portion.
  • the insole assembly generally comprises a base member 38 and a top member 40 attached to the base member preferably by stitching 42, along the peripheral edges of the two members so as to form a cavity therebetween.
  • the base member 38 is made from a relatively firm material such as board materials available from Texan, Inc. of Russell, MA and others.
  • the top member is preferably made from a stretchable material such as Spandura, , a heavy-duty nylon spandex material available from H. Warshaw and Sons, Inc. , New York, New York. Contained within the cavity formed between members 38 and 40 is a fixed position heel spacer 46 and movable ramps 48.
  • the spacer 46 and ramps 48 are preferably made from a relatively firm but flexible cellular plastic foam such as ethylene-vinyl acetate copolymer, available from Monarch Rubber Co. of Baltimore, MD and others. While two ramps 48 are shown in this embodiment one or multiple ramps such as 3, 4 or more may be employed, including opposing ramps and ramp array (not shown) .
  • the ramps preferably vary in thickness, gradually decreasing in thickness in the direction towards the toe of the shoe.
  • the insole assembly also includes adjustment mechanism comprising a rotatable thumbwheel 50 which is attached to cables 54 which cables are attached to ramps 48; the operation of which is described hereinafter.
  • a coin slot 60 can be used to control the adjustment means.
  • the insole assembly preferably includes a removable insole or cushion 44 disposed on the top surface of the top member 40 of the insole assembly. Cushion 44 is unattached, although temporary attachment may be achieved by means such as adhesive means, Velcro fasteners and the like. The cushion 44 is removable for its cleaning and the cleaning of the shoe cavity 24 as well. It is preferably made from a relatively firm but cushioned material such as a plastic foam material laminated on its top surface to a fabric or leather sheet material.
  • the adjustment mechanism generally comprises cables 54 a-d, which are fixed to and wound around cable drum 52.
  • cables 54 As the radial positioning of drum 52 is adjusted by turning thumbwheel 50, cable 54, fastened to ramps 48 and rivets 62, moves through eyelets 64 and 66 (in the base 38) in such a way as to move both ramps simultaneously in the same direction, in a manner similar to the cable-activated parallel rules commonly used on drafting boards.
  • insole assembly 36 together with a portion of the vamp 30 form a cavity in which cables 54 are free to move to permit adjustment of the ramps 48.
  • Girth adjustment is achieved by the movement of the ramps 48.
  • the fitting height d is at its maximum value.
  • the girth of the shoe is at its greatest value.
  • the fitting height d gradually decreases as the thickness in the mid-portion increases until the ramps arrive at their forward most position as best shown in Figs. 3 and 4.
  • the fitting height d' and girth are at their minimum values.
  • the fitting height and girth may be infinitely adjusted between these extremes merely by positioning the ramps 48 accordingly.
  • a removable insole assembly 70 is shown.
  • the only differences between this assembly and assembly 36 of Figs. 1-6 is the replacement of thumbwheel 50 with a turning coin slot 60.
  • Fig. 8 shows the heel portion of the assembly 70 showing the coin slot 60 flush with the bottom assembly to facilitate a smooth fit in the shoe cavity.
  • the assembly is not adjustable when the foot is in the shoe since coin slot 60 does not extend outside of the shoe.
  • Fig. 9 shows a transverse cross-sectional view of the assembly 70 at the ball portion of the foot with ramps 48 moved to their most forward position.
  • Fig. 10 shows a longitudinal side elevational view of the assembly of Fig. 7 showing again the ramps 48 in their most forward position.
  • an expandable bladder is employed to increase the thickness of the insole assembly particularly in the mid-portion of the shoe.
  • the insole assembly 80 generally comprises an expandable bladder 82, which extends throughout the mid portion into the toe portion of the shoe and a removable insole or cushion 84 disposed directly above the bladder 82.
  • the bladder 82 contains a pump/valve assembly 86 which extends through the sole 88 of the shoe 20 adjacent the breast of the heel so as to be easily accessible to the wearer to make the girth adjustment while at the same time being protected from undue abrasion during use of the shoe.
  • Fig. 11 shows the shoe at about its minimum girth with a maximum amount of air in the bladder 82.
  • the pump/valve assembly is used to adjust the amount of air in the bladder, thereby adjusting the thickness of the insole assembly and thereby the girth of the shoe.
  • the bladder may be made from any suitable material which is air impervious such as a urethane film.
  • the pump/valve assembly portion of the bladder may be any of the conventional two-way pump and valve assemblies known and used in the art. Particularly preferred pump/valve bladder assemblies are similar to those currently being used for different purposes in sneakers sold and marketed by Reebok Corp. of Stockton, MA. and LA Gear of Los Angeles, CA. While air bladders are presently preferred, bladders which employ other gases, gels or fluids may be used instead of air bladders to achieve the same result.
