Description

FIELD OF THE INVENTION

The present invention relates to a hand free footwear and foot cleaning device which allows the user to clean the bottom or the sole of the footwear as well as the exterior surrounding sides of the footwear. The device can also be used to clean a user's foot. The present invention further provides for a decreased need for movement of the foot during the cleaning process. The present invention also includes the option of incorporating additional elements for the purpose of cleaning bare feet rather than just the bottoms of the footwear.

BACKGROUND OF THE INVENTION

One of the most significant issues within the footwear industry is combating the inevitable accumulation of different contaminants and debris on the exterior sides of the footwear, as well as in the exterior sole. This is especially true when the footwear is used on clay or synthetic surfaces on tennis courts. Various debris such as dirt, mud, salt, particulates, and other undesired material are collected on the exterior surface of the footwear with regular use. Such unwanted elements, over time, diminish the appearance, material, and overall structure of the footwear. The unwanted material can also be tracked into a car or house. Because of this, footwear cleaning devices have become vital in combatting the continual buildup of unwanted contaminants on exterior footwear surfaces.

To prevent such issues, innovators have created footwear-cleaning devices which allow for the user to place their foot in the device while wearing footwear and move their foot back and forth within the device's housing to clean the exterior sole and sides of the footwear.

The present invention will improve upon the above-mentioned needed areas of progress for hand free footwear cleaning device. Factors such as the amount of foot movement needed to clean the footwear, the amount of surface-area that a device can cover, and the amount of time required to complete the footwear cleaning process are addressed by the present invention. The present invention will demand significantly less movement of the foot than the current devices require. The present invention will also clean a greater surface area of the footwear than the current devices are capable of. Lastly, the present invention will decrease the amount of time required to thoroughly clean the footwear. In addition, the invention may provide a hand free activation feature, allowing the device to begin operating upon the placement of the footwear inside of the housing of the device.

SUMMARY OF THE INVENTION

The present invention relates to a hand free footwear cleaner by using a plurality of rows of sprayers as opposed to just a single row of sprayers, and a plurality of rows of rollers as opposed to just a single row of rollers, enabling a decreased amount of movement of the footwear required for the sprayers and rollers of the device to reach and interact with the exterior sole and side surfaces of the footwear. The present invention utilizes a pressure activation to initiate the spray, or it may use a sensor to activate the spray. The presence of a sensor to activate the flow of water allows for hand free operation that eliminates the transfer of bacteria and other germs that is caused by numerous users touching a control to turn on and off the flow of water of a device. The present invention also incorporates the ability to clean bare feet, by targeting sprayers towards the top of the foot in addition to the sides and sole.
