Sandal with adjustable straps and interchangeable mix and match straps and insoles
A sandal comprised of layered footwear components includes a lower base, a middle member replaceable platform which secures the straps, and an upper member replaceable insole. A hollowed out center area creates a perimeter side wall on the top of the base into which the platform is stored. A frontal (toe area) and rear (heel area) ledge crosses the toe and heel areas of the superior base horizontally. The straps are attached to a platform and secured by a present choice of a hook and loop fastener. The front and rear of the platform is eased under the front and rear ledges on the base. A midpoint lock on the platform further secures the platform to the base. A final top layer insole is secured on top of the platform and under the overlapped straps and placed into the remaining hollow area of the base hiding the shoes components. The straps and insole cooperate to form a shoe upper for receiving the foot. Platforms and insoles are interchangeable to heel, flat or wedge style bases. Exchangeably connected straps to platforms are repeatedly adjustable in horizontal and vertical directions for comfort and mix and match to create many shoe styles. Middle member platform and upper member insole may be combined and be known as the “plate”. Hook and loop fastener will remain on the underside of the plate (formerly known as the platform), and a male lock will also be located on the underside of the plate. The male lock will releaseably contact with a female lock located on the inside of the hollow area of the base. The straps will releasably connect with the hook and loop fastener on the underside of the plate and when the plate is inserted into the hollow area of the shoe base, it will hide the shoe components and the top of the plate will become a contact support for the foot and the overlapped straps will secure the foot to the base.
This continuation in part application; is based on non Provisional application Ser. No. 11/901,316 filed on Sep. 17, 2007 which is based on Provisional Application # 60/863,013 filed on Oct. 26, 2006 and Provisional Application # 60/923,948 filed on Apr. 16, 2007.
FIELD OF THE INVENTIONThe present invention relates generally to footwear and, more specifically, to a sandal with adjustable and replaceable straps and replaceable insoles which are interchangeable to a variety of shoe bases to allow aesthetic and functional changes to the shoe.
BACKGROUND OF THE INVENTIONFootwear comes in a vast variety of styles and designs to suit numerous functional and aesthetic goals. People are all individuals with variances in body parts including their feet. Foot specifications vary in width, bone structure, toe lengths, protrusions, and varying positions of instep. Feet can swell from changes in weather, excessive walking, or increased salt intake. One foot may be wider then the other. All feet are different and individuals are often uncomfortable in over the counter footwear. The present invention enables the consumer to adjust the sandal straps up or down and adjust the width of the straps as well to increase their personal comfort. Custom molded shoes can be expensive and the present invention would offer this benefit for a moderate amount of money. The ability to alter width or strap location at any time would be a benefit to most individuals.
The present invention also offers the consumer the ability to mix and match straps and insoles to customize their shoe whenever required. An ankle strap can be removed and reapplied at any chosen time. All straps are removable and replaceable to any platform. The consumer can purchase a set of new straps with or without a new platform. Having each pair of straps mounted on its own platform makes it more convenient to simply slide and lock into the base, cover with insole and go. It will maintain the consumer's personal adjustments for next time. Any platform is transferable to any style (heel, flat, or wedge) sandal of the same size. All insoles are also transferable to any style of same size sandal. A soiled insole can be replaced when needed. All of the possible variations increase the consumer ability to affordably increase their amount of foot attire.
DESCRIPTIONThe present invention provides improved footwear that overcomes many of the limitations of the prior art. A sandal according to the present invention includes a lower base (
(Alternate lock
Another variation of the platform (
Another variation to the platform (10) and insole (24), would be to permanently combine them, and insert the two as a one piece plate (37) into the hollow area (1) of said shoe base.
Preferred choice of hook and loop fastener would remain on the underside of the platform (13) (which will now be referred to as the male plate (37) to secure the straps.
A new and improved releasable lock would consist of two reciprocal pieces of molded plastic. The shoe base (female plate) (38) being one piece with the female recipient for the male plate inside of the superior hollow area of the shoe base, and the reciprocal male molded plastic plate (37).
The underside of the (male) plate (37) contains a frontal (39) protrusion which slides forward into the female reciprocal socket (40). The protrusion continues to slide until secured under a frontal ledge (41) thereby securing the frontal plate to the frontal sole plate. After the frontal plate locks into place, a middle protrusion (43) and a rear protrusion (44) on the underside of the plate is pushed down and locks into a female middle (45) and rear reciprocal plastic recess (42) on the superior rear base. The plate fills the hollow area of the superior shoe base and creates a contact support for the foot. The releaseably locked components look and function like a usual and customary shoe.
For further security a removable rear locking pin or screw may be inserted into the rear of the sole (44) entering the rear of the plate.
Substitute choices of hardware may be used in the future to releasably secure the plate (with straps) to the base.
