Internally Illuminated Footwear Component
The sole section of a shoe includes a midsole and an outsole, with the midsole being made from a translucent material. An illumination system is located inside the translucent midsole, causing the translucent midsole to be internally illuminated when the illumination system is active. Due to the translucent nature of the midsole light from the illumination system reflects internally throughout the midsole, increasing illumination. The light will also illuminate adjacent translucent components, such as the outsole if it is also made from a translucent material. Light from the illumination system can be blocked, such as by an opaque outsole or colored mold injection, and used to form an illuminated design or logo. By blacking out or covering sections of the translucent midsole, shapes and letters of visible light can be created in the negative space of the obstruction sections. This allows illuminated designs to easily be incorporated into footwear.
The present invention relates generally to a footwear component with an internal illumination system and means of displaying graphics and designs by selectively covering light from the internal illumination system.
BACKGROUND OF THE INVENTIONUsing light as an accessory to footwear is commonly employed and has been for some time. Shoes, sneakers or otherwise, have been given various arrangements of lighting systems to enhance visual appeal of the shoe, especially towards children. Often times the lights are external to the shoe, and serve as an accessory rather than an integral part of the shoe, simply lighting up the outside areas of the shoe. Generally, the lights do not internally illuminate the shoe, instead providing illumination external to the shoe.
While there are examples of footwear with internal lighting systems, current methods of lighting a shoe can still use improvement. Some solutions simply place a few lighting elements inside the shoe, perhaps in a transparent compartment. While certainly internal to the shoe, these lighting elements don't really provide internal illumination. Some products hollow out sections of shoes, where lights are placed. Sometimes these hollowed sections have components inside, which are illuminated by the lights. Other times the sections are empty, showing light along the internal walls. These examples provide some measure of internal illumination, but leave much to be desired. Generally, only small portions of the shoe are illuminated, and even then, the shoe itself is not illuminated so much as are various components and internal surfaces which are located in the illuminated section.
It is therefore an object of the present invention to provide an internally illuminated component for a shoe. It is a further object of the present invention, to provide a method of obstructing the internal illumination, to create visual designs along the external surface, of the internally illuminated component.
All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.
An internally illuminated footwear component comprises a sole section 1, an illumination system 2, and an illumination housing 3, shown in
The sole section 1 further comprises a translucent midsole 11 and translucent outsole 12, which themselves are respectively positioned in the midsole area and an outsole area. In the preferred embodiment, this sole section 1 is molded as a single translucent component, as depicted in
Though the preferred embodiment describes the present invention as being a singularly, solid molded component, that being the sole section 1, it is also possible to mold the sole section 1 as separate pieces. In such a variation, the translucent midsole 11 would be molded independently from the translucent outsole 12. The two individual components would then be connected to form the whole sole section 1. In this variation, the sole section 1 is essentially identical to that of the preferred embodiment, with the only key difference being the assembly method. The illumination system 2 and illumination housing 3 are still located in the translucent midsole 11, while the welt 6 remains atop and around the translucent midsole 11. Likewise, the bottom face of the translucent outsole 12 contains a tread pattern. Examples of this variation can be seen in
In another embodiment, the sole section 1 comprises a translucent midsole 11 and an opaque outsole 13. This embodiment shares many aspects with the preferred embodiment. Located in the translucent midsole 11 is an illumination housing 3, which itself contains an illumination system 2. The translucent midsole 11 also includes a welt 6, positioned around the top of the translucent midsole 11. The opaque outsole 13, similar to the translucent outsole 12 of the preferred embodiment, includes a tread pattern along the bottom face. The differences in this other embodiment are related to the opaque outsole 13. The opaque outsole 13 obstructs views of the internally illuminated translucent midsole 11, preventing the translucent midsole 11 from being seen from the bottom face of the footwear; as a result, only the outer side surfaces of the translucent midsole 13 is illuminated. To take advantage of this, sections of the opaque outsole 13 can be removed, allowing corresponding sections of the translucent midsole 11 to be seen through the cut areas of the opaque outsole 13. By removing specific areas, logos, designs, and other illustrations can be formed in the opaque outsole 13. Since the internally illuminated translucent midsole 11 is visible through these areas, the logos, designs, and other illustrations appear to be illuminated. There are different ways of implementing these areas, discussed later as blackout methods. An example of an opaque outsole 13 is shown in
As mentioned in the above other embodiment, the sole section 1 can be built from a single mold, or assembled from two molds. Since the translucent midsole 11 and opaque outsole 13 have different properties, a multicolor mold is needed if the sole section 1 is built from a single mold. Alternatively, if the translucent midsole 11 and opaque outsole 13 are molded individually, the two components can be connected to form the sole section 1.
In a third embodiment, seen in
In the preferred embodiment the illumination housing 3 is cut into the top of the translucent midsole 11, illustrated in
One option is to cut access holes in the lasting board prior to connecting the separately built upper to the lasting board. The access holes correspond in shape and size to the illumination housing 3. The access holes in the lasting board would be slightly larger in size than the illumination housing 3, thus allowing for easier alignment of the lasting board with the illumination housing 3 during the manufacturing process. Alternatively, the access holes can be cut from the lasting board after connecting the separately built upper to the lasting board. As with the first option, this will still result in access holes that expose the illumination housing 3, visible after removing the footbed or insole.
In other embodiments, where the translucent midsole 11 is molded separate from the outsole, the illumination housing 3 could alternatively be cut into the bottom of the translucent midsole 11, rather than the top. In this configuration, the illumination system 2 is held in place by friction as well as the outsole. Prior to connecting the outsole to the translucent midsole 11, the illumination system 2 must be placed in the illumination housing 3. After the outsole is connected to the translucent midsole 11 the illumination system 2 will no longer be accessible, unless the maker designs an outsole which is removable from the translucent midsole 11. This is in contrast to the preferred embodiment, where the illumination system 2 may be accessed from the top by removing a shoe insert.
The illumination system 2 comprises a power source 21, a plurality of electrical wires 22, and a plurality of illumination sources 23, examples of which can be seen in
A wide variety of LEDs are available and can be used to achieve different effects as part of the illumination system 2. In addition to being available in different colors, LEDs can have different brightness values and viewing angles. LEDs with narrower viewing angles can be used to provide more intense beams of light, while larger viewing angles will provide a wider, more diffuse coverage of the translucent midsole 11. LEDs with different colors and brightness can be used together to create colorful and intriguing visual displays. A large amount of combinations are possible given the variety of LEDs in terms of color and other attributes.
In all embodiments, a variety of “blackout” methods can be implemented. The blackout methods are ways of blocking light from the internally illuminated translucent midsole 11 (and translucent outsole 12, when applicable). By strategically blocking light, it is possible to incorporate designs, logos, and other embellishments with the present invention. There are six different implementations of the blackout method. Each variation of the blackout method uses a plurality of outsole design sections 131, while some also require the use of a plurality of design inserts 14. The outsole design sections 131 and design inserts 14 can take numerous forms, depending on the intended overall design. A common and simple design is a word across the sole of the footwear, such as the name of the product or brand. In this instance, the individual outsole design sections 131 and design inserts 14 are simply the letters that form the product name.
The first blackout method, shown in
The third blackout method, similar to the first blackout method, cuts a plurality of outsole design sections 131 from the outsole to define a design or illustration as illustrated in
A fourth blackout method, depicted in
Visible in
The sixth blackout method, similar to the first method, cuts the plurality of outsole design sections 131 from the opaque outsole 13. In this blackout method, the cuts are made in a stencil style, seen in
The various blackout methods can be applied anywhere along the sole section 1. It is even possible to blackout illumination from the side of the translucent midsole 11 or sole section 1, whether through a multicolor mold or by extending the opaque outsole 13 to cover parts or all of the side of the translucent midsole 11. Resultantly, designs, logos, and other arrangements could be incorporated across the sides of the sole section 1 and translucent midsole 11, an example of which can be seen in
In other embodiments the translucent midsole 11 may not be solid, but instead built with a skeleton design, resulting in a skeleton midsole. The skeleton midsole has open interior sections 111 formed by internal and external walls 113, which can be produced in various arrangements, such as those shown in
When employing a skeleton midsole there are three variations in how the illumination system 2, skeleton midsole, opaque outsole 13, and outsole design sections 131 are combined and arranged. In a first variation, the illumination system 2 is installed in the bottom of the skeleton midsole, with the outsole design sections 131 being positioned to overlap with the plurality of illumination sources 23. In a second variation, the illumination system 2 is also installed in the bottom of the skeleton midsole, but the outsole design sections 131 do not overlap the plurality of illumination sources 23. Examples of a bottom mounted illumination system 2 are shown in
In the first variation, the outsole (
In the second variation, as with the first variation, the outsole (
In the third variation, the outsole (
In addition to the mentioned embodiments there are a multitude of slight variations that could be made to the present invention. While a preferred solid midsole and a skeleton midsole have been described, the two concepts could be combined in a single design, such as in
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
