## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority from U.S. Provisional Patent Application No. 61/823,294, filed May 14, 2013, the entire contents of which are incorporated by reference herein.


TECHNICAL FIELD
The present invention relates generally to a shoe or other footwear with an automated closure mechanism which is activated without the use of the user's hands by activating the closure mechanism through an interaction between the user's foot and the sole of the shoe or footwear. The disclosed shoe and automatic closure mechanism operates through a series of motors which manipulate retractable leather, textile or other material making up said shoe. The material making up the shoe can be rolled up or otherwise retracted into the sole of the shoe, thus allowing a user to easily put on or take off the shoe without bending down to reach the height of the user's feet.
The disclosed shoe and automatic shoe closure mechanism has particular application for types of shoes that are inherently difficult to attach to a user's foot, such as formal leather shoes with rigid sides and narrow laces. Additionally, the disclosed shoe and automatic closure mechanism has application to user's who lack the motor skills required to attach a shoe to a foot, in particular, children, the elderly and individuals who have suffered injuries or illness causing immobilization or a lack of motor skills in their hands, legs, feet or back. Further, the disclosed shoe and automatic closure mechanism can particularly assist individuals with limited mobility by preventing injuries from occurring by utilizing hands-free operation of the automatic closure mechanism described herein.
Discussion of Related Art
There are a wide variety of standard attachment mechanisms for uses in different styles of shoes and other footwear. For example, laces, Velcro, leather straps, metal straps, hooks, and the like. Attempts have been made in the past to create automatic closure mechanisms for footwear with limited success, including automatic lace tightening systems and the like. However, none of the existing shoe closure mechanisms allow a user to effortlessly place their feet into the appropriate locations of the top of a sole of the shoe or footwear and automatically attach said footwear automatically without any involvement of the user's hands.
There exists a need for an automatic shoe closure system that allows a user to both properly place their foot in a shoe and attach the shoe to the user's foot securely and then later remove the same shoe without the use of the user's hands.
SUMMARY
Exemplary embodiments of the present invention provide a shoe and automatic shoe closure mechanism which allows a user to both place a shoe about their foot and securely attach and later remove said shoe in a hands-free format.

The magnets may have sufficient magnetic strength to secure panels 201, 202 and 203 about a user's foot to allow for safe walking and mobility. However, connectors 301, 302, 303, 304, 305 and 306 could be any type of connector which can automatically secure panels 201, 202 and 203 about a user's foot to allow for safe walking and mobility; such as hooks, clasps, Velcro, electromagnets, reusable adhesives, or the like, which can be used alone or in combination with magnets or similar devices.
Referring to FIG. 1, shoe 100 can be removed in both a manual and hands-free format. Panels 201, 202 and 203 may be completely retracted into sole 200 by being wound up around motors 401, 402 and 403 through the rotation of motors 401, 402 and 403 in a direction opposite to the direction used to expand panels 201, 202 and 203. Motors 401, 402 and 403 are activated in the direction to wind up panels 201, 202 and 203 through one of a plurality of mechanisms. One such mechanism is by depressing retraction button 502. Retraction button 502, shown in FIG. 1, may rests in a recessed pocket on one side of sole 200. Retraction button 502 may be placed anywhere around sole 200. The recessed pocket housing retraction button 502 may be sufficiently deep such that retraction button 502 will not be unintentionally depressed without deliberate intent on the part of the user. Retraction button 502 is sufficiently accessible, such that it can be activated by being depressed by the user's finger. However, retraction button 502 could also be operated in a hands-free format be deliberately pressing the user's shoe against a surface or object with a protrusion that is shaped and dimensioned to reach button 502 within its recessed pocket.
The winding up of panels 201, 202 and 203 around motors 401, 402 and 403 to retract the panels into sole 200, may additionally operate to automatically disconnect panels 201, 202 and 203 from each other.
Referring to FIG. 1, another method for removing shoe 100 by activating motors 401, 402 and 403 in the direction to wind up panels 201, 202 and 203 is through the use of a Smartphone software application which communicates with a wireless receiver positioned in sole 200. This embodiment facilitates hands-free removal of the shoe 100 by the user activating motors 401, 402 and 403 from a Smartphone handset, which wirelessly communicates with Shoe 100.
Referring to FIG. 1, another method for removing shoe 100 by activating motors 401, 402 and 403 in the direction to wind up panels 201, 202 and 203 is through the use of a remote control. This embodiment facilitates hands-free removal of the shoe 100 by the user activating motors 401, 402 and 403 from the remote control, which wirelessly communicates with Shoe 100. The remote control may be sufficiently small that the user could carry it with them at all times in a pocket or about their person. The remote control may be mounted on a wall or near an entranceway to a home, or in another location where a user frequently puts on or removes footwear.
Referring to FIG. 1, motors 401, 402 and 403 may each be powered by one or more batteries which is/are contained within sole 200.
Referring to FIG. 1, the battery or batteries used to power motors 401, 402 and 403 are charged by connecting a power supply through port 503.
Referring to FIG. 2, one embodiment of an article of footwear is shown with a perspective view of shoe 100 showing a view of panels 201, 202 and 203 partially extracted from sole 200 and another view of panels 201, 202 and 203 connected to each other to create an exemplary embodiment of an assembled item of footwear.
FIG. 2 is a perspective view of an exemplary embodiment of the present invention showing retraction and expansion slits for footwear panels and footwear panels in both partially and fully expanded positions; and a fully assembled shoe.
Referring to FIG. 2, shoe 100 is additionally show with slits 201a, 202a and 203a visible in sole 200. Slits 201a, 202a and 203a may allow panels 201, 202 and 203 to fully retract inside sole 200 through the rotation of motors 401, 402 and 403.
While slits 201a, 202a and 203a are shown in the sides of sole 200, similar slits may alternatively be placed on the top, outer edge of sole 200, such that panels 201, 202 and 203 would expand in an upward direction our of the sole 200. For example, the positioning of the slits 201a, 202a and 203a on the top of the sole 200 may prevent dirt, mud and other similar debris from entering the sole of the shoe. Alternatively, similarly slits could be placed at any desired angle with respect to sole 200 to guide panels 201, 202 and 203 in a desired direction upon expansion/unwinding out of sole 200. Such alternative slits may be desirable based on the use of different fabric compositions for panels 201, 202 and 203.
Referring to FIGS. 1 and 2, shoe 100 with panels 201, 202 and 203 fully retracted into sole 200, a shoe can be placed about a user's foot without the use of the user's hands by the user positioning their foot in the appropriate position with respect to sole 200 and stepping down onto expansion button 501. Upon pressing button 501, panels 201, 202 and 203 may fully expand from within sole 200 and automatically connect and associate with each other to snuggly fit around the user's foot. A user can then walk about in a normal fashion.
When a user desires to remove shoe 100 in a hands-free format, the user can re-activate motors 401, 402 and 403 to disconnect panels 201, 202 and 203 from each other and retract panels 201, 202 and 203 back into sole 200. Re-activation of motors 401, 402 and 403 may be accomplished through the use of the Smartphone application or a remote control which wirelessly communicates with motors 401, 402 and 403. Alternatively, button 502 can be depressed in either a hands-free or manual format to similarly re-activate motors 401, 402 and 403.
From the foregoing and with reference to the drawings, those skilled in the art will appreciate that certain modifications can also be made to the exemplary embodiments of the present invention without departing from the scope of the same. Therefore, the above descriptions should not be construed as limiting, but merely as exemplifications of particular embodiments.
