Abstract
Description
- 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 the heel and to a toe puff at the front to stiffen the point of the shoe. This is particularly so in the case of sports shoes such as snow shoes and mountaineering boots. Usually different materials are used for different parts of this assembly because the stiffness of various parts of the shoe must be different. During assembly various parts have to be connected to each other by stitching and/or by adhesive. Very often the stitching projects from the insole surface and this can be uncomfortable for the person wearing the shoe.
- An object of this invention is to provide an economical one-piece insole including all the necessary parts which will simplify assembly and production of the eventual shoe, which can be produced by utilizing standard equipment in the footwear industry.
- With this object in view, the present invention provides an insole formed in one piece with a boxed-in toe puff, a raised edge heel counter, by injection moulding of plastics material.
- Preferably, 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.
- The invention will be described further, by way of example, with reference to the accompanying drawings, in which:
- Fig. 1 is a perspective view of a preferred embodiment of an insole according to the invention;
- Fig. 2 is a longitudinal section according to line II-II in Fig. 1;
- Fig. 3 is an upside down view of the insole shown in Fig. 1 and the supporting strips which can be attached thereto;
- Fig. 4 is a section according to line IV-IV in Fig. 3; and
- Fig. 5 is a partial section of an assembled shoe incorporating the insole shown in Figs. 1 to 4.
- With reference to the drawings, 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 aheel counter 3 is integrally formed. Theheel counter 3 is formed as a raised edge at the central back part of the heel. - These three parts, namely the
insole element 1, thetoe puff 2 and theheel counter 3 are formed in one piece by a conventional method of injecting plastics material into an appropriate mould. - On the upper surface of the
insole element 1 there are two grooves orchannels 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 offlexing cuts 5 along its free edge enabling it to adapt itself as the shoe bends during walking. - Between the
toe puff 2 and the heel counter 3 aside connecting edge 6 is provided which can either be lower or higher as shown by thedotted line 7. - The
insole element 1 has a flexible and deformablecentral region 8 which is not as thick as the side or edge regions. - By appropriate selection of the thickness over the entire insole, varying deformability can be obtained thus making some parts more flexible and other parts stronger and stiffer.
- The lower surface of the
insole element 1 has alongitudinal channel 9 for receiving a stiff metal supporting strip orleaf spring 10 of the same size as thechannel 9 which is attached by rivets passing through therespective holes 11 on thestrip channel 9 may receive a portion 13 which is partially cut out of a larger supportingstrip 14. This sort ofstrip 14 is additionally held in place by rivets passing throughholes 15 in thestrip 14 and correspondingholes 16 in theinsole 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. - 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. - The combination of such insoles with metal supporting strips of different sizes and forms allows for shoes with specific characteristics for special uses. Indeed, the insole of the invention is particularly suitable for use in making sports footwear such as snow shoes and mountaineering boots.
- It will of course be understood that the foregoing is illustrative and not limitative of the scope of the invention and variations are possible within the scope of the claims.
