Description

    RELATED APPLICATIONS
  • This application claims the benefit of U.S. Provisional Application Ser. No. 61/873,421, filed Sept. 4, 2013.
  • BACKGROUND OF THE INVENTION
  • Smart footwear is defined as footwear having embedded mechanical and electrical systems for performing various functions. Embedded systems may be located anywhere on the shoe, but it is desirable, both for function and aesthetic reasons, that the embedded system be hidden in the insole of the shoe. Typical examples of such systems include energy harvesting devices, footwear-embedded GPS devices and step-logging (pressure sensing) devices. Devices hidden in the insole of the shoe require support material for the embedded device to prevent damage from impacts from the user's foot and from moisture that may be present within the shoe.
  • Off-the-shelf after-market insoles are frequently made to be cut-to-fit. A range of sizes will be marked on the insole so that the user can cut the toe end of the insole to personalize the size. However, optimal fitting depends on user precision, and the insole can easily be ruined by user error, rendering the entire system unusable. For an insole without an embedded system, two insoles are typically offered for purchase in one package, or the user can buy another insole for a relatively low cost if the insole is ruined by user error.
  • Insoles for smart footwear, however, have a much higher expected cost and cannot be repurchased as easily. Other problems related to embedded systems within insoles include added wear on those systems from machine washing, replacement of the soft (comfort-related) materials from wear, and the high cost of customization due to aesthetic desires like color. Therefore, it is desirable to provide an insole design that addresses these deficiencies, while supporting a wide variety of embedded systems.
  • SUMMARY OF THE INVENTION
  • A novel two part insole is presented for use with any mechanical mechanism or electronic device located in the heel of an insole. The two part insole construction is designed for both stability and support of the embedded system present in smart footwear, as well as for comfort of the user, while still addressing the cut-to-fit and reusability constraints desirable for insoles.
  • The insole is provided as a two-part construction having a bottom layer and a top layer. The bottom layer is a more rigid construction and provides stability and encasing for engineered systems. The top comfort layer is detachable from the bottom layer, is customizable by material, color, and size, and consists of a softer, more flexible material for the comfort of the user. The insole layers may be attached to each other using grooves, adhesives, or detachable materials like Velcro. The toe end of the top layer of the insole may be provided with a cut-to-fit pattern for user fitting, or maybe provided pre-sized from the factory.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 shows an exploded view of the segmented insole of the present invention.
  • DETAILED DESCRIPTION OF THE INVENTION
  • Smart footwear having engineered devices embedded in the insole are best served by a two part insole where the cheaper, top comfort layer 1 of the insole can be customizable and removable, while the lower, more rigid layer 2 supports the embedded device. The present invention is a two part insole for this purpose. The system includes an upper insole layer 1 for comfort, having cut-to-fit lines on the toe end thereof for customizability, and a lower insole layer 2 for support, having a cavity 5 of variable shape for embedding mechanical and electrical systems. An attachment method between the lower support 2 and upper comfort insole layer 1 is provided. The insole may also feature treads on the base of the insole for inducing friction between the insole and the base of the shoe.
  • The smart footwear insole of the present invention is shown in FIG. 1. Top, comfort layer 1 is thin at the heel-end, becomes thicker under the arch at the arch point, and tapers to be thinner by the toe end. A notch 4 at the arch point is shaped to mate with bottom support layer 2. Cut-to-fit lines 3 are marked on comfort layer 1, such that the user can cut comfort layer 1 to their personal foot/shoe size along one of cut-to-fit lines 3.
  • Comfort layer 1 is preferably made of a soft, shock-absorbing material, such as gels, fabrics, foams, recycled material, or plastic materials common to comfort-based, standard orthotics. Support layer 2 provides stability for the user's foot, as well as support for the embedded device. It is preferably constructed of a structural material, such as hard plastics, composites, metals, foams, recycled material or any other structural material suitable for the base of an insole, and provides a step-down surface to protect any mechanical or electrical systems embedded within embedded systems cavity 5. Embedded systems cavity 5 may be of any shape depending on the design of the particular embedded system, and may include channels for antenna, wires or other parts which are required to be positioned external to the insole (not shown). In a second embodiment of the invention, support layer 2 may comprise a two-part construction defining a cavity on the interior thereof such that the embedded system is completely encased by the rigid material of support layer 2. In such cases, the two parts of support layer 2 may be attached to each other using methods similar to those used to attach the whole support layer 2 to comfort layer 1. In other embodiments, the embedded systems may be manufactured already permanently or non-permanently encased in support layer 2, ready to be joined with comfort layer 1.
  • The length of support layer 2 will preferably not exceed the length from the heel to arch point 4. Comfort layer 1 may be attached to the top side of support layer 2 using grooves, pegs, friction-inducing fixtures, adhesives or other fixtures in the materials. In the embodiment shown, two pads 6 are shown to represent a hook and loop attachment method, such as Velcro®. The strips are orthogonal to the user's foot, but other embodiments could be in any arrangement on the outward faces of support layer 2 and comfort layer 1.
  • In another embodiment, comfort layer 1 would be thicker at the heel end with a separate pocket for support layer 2. Support layer 2 would then fit into a fabric pocket to be fastened to comfort layer 1 (not shown). In this embodiment, the fabric pocket would replace the strips of attachment material 6 seen in the embodiment of FIG. 1. In yet another embodiment, comfort layer 1 may define a cavity in the heal portion thereof into which support layer 2 may be inserted (not shown).
