Definitions

  • the present invention concerns an insole designed to incorporate both a toe puff and a heel counter, particularly suitable for use in the manufacture of sports shoes.
  • Insoles designed in various styles and materials are well known for being formed as a special flat element which during assembly of a shoe is attached to a counter which provides reinforcement to a heel and to a toe puff at the front to stiffen the point of a shoe. This is particularly so in the case of sports shoes such as sports shoes and mountaineering shoes.
  • a ski boot having an inner boot formed in one piece with a boxed-in toe puff and a raised rear leg portion or quarter and which is formed by injection moulding a plastic material.
  • the inner boot is designed exclusively for use inside a ski boot shell, and for imparting rigidity thereto, and has formed thereon protrusions which penetrate openings formed in the shell for holding the inner boot in position.
  • ski boot for FR-A-2,119,653 solved the problems of how to hold an inner boot in a correct position within a ski boot shell, and how to realize a stiff inner boot for imparting rigidity to the shell, this known type of inner boot could not readily be applied to any other type of footwear, because the protrusions which allow attachment of the inner boot to the shell by penetrating the shell can only be used with a shell having the necessary openings formed therein, and its characteristics of rigidity may be unsuitable for other types of footwear.
  • BE-A-384,248 discloses an insole having a thicker outer region and a thinner central region for obtaining a stiffer outer region and a more flexible central region.
  • stiffness characteristics of this insole may be ideal for one type of footwear, they may be completely unsuitable for another type of footwear, thus compelling the footwear manufacturer to stock a number of different types of insoles according to the different stiffness characteristics of each different type of footwear produced.
  • Prior patent BE-A-384,249 deals with the technical problem of how to impart an anotomic shape to an insole, to increase the surface area of contact between a wearers foot and the upper surface of the insole, and to this end, proposes the use of a metal strip or leaf spring embedded within the thickness of the structure of the insole. While this solution thus provides a means of imparting an antomic form to an insole, as well as a certain degree of rigidity, a footwear manufacturer would still have to compulsorily stock a number of different types of insoles having different characteristics of flexibility according to the different stiffness characteristics of each different type of footwear produced.
  • an aim of the present invention is to provide an insole which can be readily and easily adapted for use in different types of footwear.
  • an object of the invention is to provide an insole which can be easily and rapidly adapted for imparting specific characteristics to footwear for special uses such as different types of sports footwear.
  • Another object of the invention is to provide an insole which simplifies footwear manufacture and which allows a footwear manufacturer to stock only one type of insole, which can then be easily and rapidly adapted as required for use in the different types of footwear.
  • a further object of the invention is to provide an insole which can be installed in a footwear item in such a way that it permits the attachment of accessories to the footwear item.
  • a not least object of the invention is to provide an economically advantageous one-piece insole including all the necessary parts which will simplify assembly and production of the eventual shoe or footwear, and which permits production of such footwear by utilizing standard equipment in the footwear industry.
  • a still further object of the invention is to provide a method of manufacturing an insole which can be easily and rapidly adapted for imparting specific characteristics to footwear for special uses such as different types of sports footwear.
  • an insole comprising at least one substantially flat element, a boxed-in toe puff formed at a front portion of said substantially flat element, a heel counter formed at a central back part of the heel portion of said flat element, and connecting edges laterally delimiting said flat element, interconnecting said toe puff and said heel counter and being connected to the upper surface of said flat element, said flat element, said boxed-in toe puff, said heel counter, and said connecting edges being contemporaneously formed by injection moulding a plastic material, characterized in that said insole further comprises selected support means, connected to said flat element and being adapted for selectively imparting to at least a portion of said substantially flat element a desired degree of stiffness according to the type of footwear in which said insole is to be used.
  • an insole comprising the step of:
  • the insole is also formed with varying degrees of thickness for the obtainment of different degrees of local stiffness, as well as channels in its upper surface for stitching and a channel in its lower surface for housing either an entire supporting strip or a part thereof.
  • a preferred embodiment of the insole of the invention comprises a flat element, which is anatomically formed so as to resemble the underside of a foot, at the front of which a boxed in toe puff 2 is integrally formed and at the back of which a heel counter 3 is integrally formed.
  • the heel counter 3 is formed as a raised edge at the central back part of the heel.
  • the insole element 1 On the upper surface of the insole element 1 there are two grooves or channels 4 adjacent the side edges. These reduce the insole thickness and are designed to contain some assembly stitching when the rest of the shoe, namely the upper and sole are attached to the insole. In this way the stitching stays beneath the level of the upper surface of the insole and therefore no discomfort is caused to the wearer of the shoe.
  • the toe puff 2 has a plurality of flexing cuts 5 along its free edge enabling it to adapt itself as the shoe bends during walking.
  • a side connecting edge 6 is provided which can either be lower or higher as shown by the dotted line 7.
  • the insole element 1 has a flexible and deformable central region 8 which is not as thick as the side or edge regions.
  • the lower surface of the insole element 1 has a longitudinal channel 9 for receiving a stiff metal supporting strip or leaf spring 10 of the same size as the channel 9 which is attached by rivets passing through the respective holes 11 on the strip 10 and 12 on the insole.
  • the channel 9 may receive a portion 13 which is partially cut out of a larger supporting strip 14. This sort of strip 14 is additionally held in place by rivets passing through holes 15 in the strip 14 and corresponding holes 16 in the insole 1.
  • the strip 14 in this case extends rearwardly and at its end is formed as a hook 19 which will project from the assembled shoe.
  • the insole In use the insole is assembled with an upper 17 and a sole 18 and these are attached together by stitching etc. to form a shoe, as illustrated in Fig. 5.
  • the insole has the desired stiffness and local deformability suitable for the use to which the shoe is to be put. It maintains its shape and does not alter the product in any way. Its shape is very important because with the toe puff and heel counter integrally formed it simplifies manufacture of the shoes. Moreover, the orthopaedic and functional characteristics of the product are improved.
  • the stitching which is necessary for attachment of the sole, upper and insole is contained in the channels 14 which prevent the thread from being ruined or from causing discomfort to the foot.
  • insoles with metal supporting strips of different sizes and forms allows for shoes with specific characteristics for special uses.
  • the insole of the invention is particularly suitable for use in making sports footwear such as snow shoes and mountaineering boots.
