Zippered shoe sole with one or more compartments
The current invention is directed toward an item of footwear with upper and lower soles, which are removably attached to each other by a zipper, where the sole contains one or more compartments created by mating cavities formed into the mating faces of the upper and lower soles. Access to the compartment(s) is achieved through zippers and a flexible sole. A zipper is located along the fringe of the sole, separating the sole into an upper sole and a lower sole. A zipper encompassing the entire fringe of the sole allows for complete removal of the lower sole. A zipper encompassing part of the fringe combined with the flexible sole allows easy access to a compartment. The existence of a compartment is, optionally, hidden by making the zipper the same color as the sole, or by hiding the zipper under a protective sleeve.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENTThis invention was not federally sponsored.
BACKGROUND OF THE INVENTION Field of the InventionThis invention relates to footwear, and more specifically, to footwear with one or more compartments incorporated in the sole. Footwear has existed for thousands of years, but significant improvements on the design of footwear only started a couple of hundred years ago. From shoelaces to rubber soles, footwear has increased in durability, functionality, and ease of use. Shoes are now adapted to specific situations to fulfill specific needs. As people travel outside their house, there is a need to store important items on his or her person, including keys, identifications cards, credit cards, or the like.
While performing athletic activities, such as running, walking, tennis, etc., retaining these items may be difficult because carrying a bag to hold these items or placing them in a pocket would hinder an athlete's performance. Also, when traveling in areas where theft and pick pocketing is a possibility, a hidden location to store important items is highly desirable. At the same time, these items must be easily accessible for use when needed.
The prior art has several examples of attempts to resolve this problem. U.S. patent application Ser. No. 10/823,683, to Shih, discloses a sole with a zipper that attaches the sole to the shoe cover. The entire sole may be removed, and replaced by other soles. While this may allow for one shoe to adapt to many different situations, this invention does not provide compartments or areas to retain items inside of the sole itself in which things of value can be stored or hidden.
U.S. patent application Ser. No. 10/295,679, to Gross, discloses layers of soles that can be attached together by means of a zipper. One or more soles can be placed together to create varying thicknesses of a sole of an item of footwear. Though Gross discloses a sole that is split into multiple levels, there are no compartments in or between these levels. Furthermore, even if Gross did teach a compartment in between layers, Gross' preferred method of attachment, namely, two prongs coming out the upper side of each layer, would not provide the side closure that is taught by the present invention; it would be quite easy for a key left in between the layers of Gross' invention to slide out during a walk or run.
U.S. Pat. No. 5,921,008, to Ruff, discloses a compartment with a drawer contained in the heel of an item of footwear. The drawer slides in and out of the compartment freely and is secured within the heel of the shoe by an external strap which connects to the shoe by a hook-and-loop fastener. This external strap may become detached, though, during physical activity, causing the drawer to slide out and the contents of the drawer to become lost. Additionally, removing and replacing the drawer, as well as continuously checking the strap is secure, is burdensome to the wearer of the shoe. The external strap will also notify prospective pickpockets as to a possible location of valuables on the person. Finally, to create a cavity into which the drawer can slide, which is sturdy enough to withstand the weight of a 200 pound or more runner and not deform to the point where the drawer could not be removed after a run, it would be necessary to use a very strong material, such as aluminum, which is also relatively heavy when compared with the weight of the average shoe sole. In addition, the heel of the shoe is one of the major parts of the shoe where it is desirably to have considerable cushioning, to protect the heel of the foot. Putting a metal-lined drawer cavity only millimeters below the heel of the user would be counterproductive to the goal of providing a heel cushion in the shoe.
U.S. Pat. No. 6,898,875, to Ruff, discloses a compartment with a drawer contained in the heel of an item of footwear. The drawer is retained in the shoe by means of an elastic thread inside the shoe and cannot be removed from the shoe by the user. Because of the mechanical limitations of the drawer and the elastic thread used to retain the drawer, only a fraction of the entire footprint of the shoe can be used to store items. The elastic thread retaining the drawer may wear out over time and cause the drawer to hang out of the shoe. Any external protrusions from the shoe will notify prospective pickpockets as to a possible location of valuables on the person.
Thus there has existed a long-felt need for footwear where the sole contains one or more compartments that are secure, reliable, hidden, and large enough to carry multiple various items.
The current invention provides just such a solution by having an item of footwear with a sole, where the sole contains one or more compartments, comprising at least an upper portion and a lower portion. These compartments may extend to edges of the sole, limited only by necessary support for the upper portion of the sole, such that a user of the invention has adequate support for his or her feet while using the shoe. Access to the compartment(s) is achieved through zippers and a flexible sole. A zipper is located along the fringe of the sole, separating the sole into an upper sole and a lower sole. A zipper encompassing the entire fringe of the sole allows for complete removal of the lower sole. A zipper encompassing part of the fringe combined with the flexible sole allows easy access to a compartment. The existence of a compartment or compartments can be hidden by making the zipper the same color as the sole, or by hiding the zipper under a protective sleeve.
Unlike the prior art, the current invention has one or more compartments where the items contained therein are less likely to be lost. Drawers retained by hook-and-loop fastening straps can become easily dislodged from the shoe during physical activity. Elastic threads can wear out and become loose. Drawers can fall out of the compartment or, through the consistent pounding of a heavy jogger on the top of the cavity into which the drawer fits, become jammed inside the shoe. The current invention solves this problem by allowing direct access to the compartment, then sealing the compartment with a zipper. Further, a drawer, especially with a strap, is more visible to possible thieves than that of a zipper made to be the same color as the sole, especially when hidden by a protective sleeve.
Additionally, the compartments in the current invention allow for more usable space than that of a drawer. There is no need for the extra space required by a drawer with its corresponding reinforced cavity, and a fastening device. Since there is direct access to each compartment, the entire sole of the footwear can be utilized, not just the heel, resulting in additional space to store valuable items. This simpler design will also result in reduced manufacturing costs.
SUMMARY OF THE INVENTIONIt is a principal object of the invention to provide an item of footwear having compartments for storing multiple various items in the sole of the footwear.
Other objects of the invention include the following.
To provide an item of footwear having easy access to one or more compartments in the sole of the footwear.
To provide an item of footwear where the zipper between the upper sole and lower sole can be colored to either contrast with the one or more colors found in the upper and lower soles, for fashion, or to blend in with the colors found in the upper and lower soles to disguise the existence of the cavities.
To provide an item of footwear where the zipper between the two compartments can be hidden from the view of others by a covering of vulcanized rubber or some other material, which will disguise the existence of the zipper.
It is a final object of the invention to provide an item of footwear where compartments are hidden so that they do not attract the attention of possible thieves.
It should be understood that while the preferred embodiments of the invention are described in some detail herein, the present disclosure is made by way of example only and that variations and changes thereto are possible without departing from the subject matter coming within the scope of the following claims, and a reasonable equivalency thereof, which claims I regard as my invention.
