This application is related to US Provisional Application No. 61/089003 filed on August 14, 1008, and claims the priority of that filing date.
BACKGROUND- Field of Invention
The current invention relates to a new sandal design, featuring an adjustable strap where the strap closure or adjustment is hidden below the sole. In one example, this new design is created by making "slits" in the sole of the sandal so that the straps can come through to the bottom of the sole in front of the heel and can be tightened or loosened via a hook and loop fastener.
BACKGROUND- Prior Art
Prior art sandals typically provide either fixed straps that cannot be adjusted, or a visible adjustment means such as buckles or hook and loop fastening. This adjustment is typically provided on the top or sides of the straps above the sole.
There is a need for an adjustable but stylish sandal to enable the sandal to fit wide or narrow feet, as well as to be adjusted for comfort if the users' feet are temporarily swollen. The current invention addresses those needs with various embodiments of sandals or shoes with hidden adjustment means.
SUMMARY OF INVENTION
In one embodiment of the current invention, one or more strap of a sandal is adjustable below the sole of the sandal so that the adjustment mechanism may be hidden in order to provide an improved appearance of the shoe. The adjustment mechanism may include a hook and loop fastener, a buckle, a snap, a tying of the straps or strings.
In one embodiment of the current invention, holes are provided in either the front or the back of the shoe in order to permit straps or strings to be routed below the sole.
In one embodiment of the current invention, a wedge-shaped heel is provided so that a compartment is created in the heel wedge in order to hide and protect the strap or other adjustment mechanism. This compartment may be covered or may be left uncovered.
In one embodiment of the current invention, the upper part of the shoe is tied to the foot by routing wide straps or strings through the sole and then securing the straps or strings to each other below the sole. In one embodiment of the current embodiment, an adjustable shoe is provided for children to allow for the periodic adjustment of the size of the shoe.
In the various embodiments of the current invention, several types of fastening devices and methods may be used including buckling the straps, snaps, tying the straps, or pinning or clamping the straps.
DESCRIPTION OF FIGURES
FIG. 1 is a side view of a hook and loop fastening device for a sandal strap.
FIG. 2 is an enlarged bottom perspective view of the sandal of FIG. 1 showing the hook and loop fastening means for a sandal.
FIG. 3 is an enlarged side bottom view of the sandal of FIG. 1 showing the hook and loop fastening for the sandal.
DESCRIPTION OF EMBODIMENT - Sandal with rear strap adjustment positioned below sole
In this embodiment, a sandal 100 is provided with a first side strap 210 and a second side strap 220 as shown in FIG. 1. In this example, the sandal includes a front strap or retention element 230 which is not adjustable. The sandal includes a sole 102 and a heel 105. In this example, the hook and loop fastening means is located in an offset space adjacent to the heel. In this example, two straps 210 and 220 can be adjusted as desired with the hook and loop fastening device where one portion of the hook and loop device is provided on the first strap 210, and another portion of the hook and loop device is provided on the second strap 220. Since the adjustment means 200 is located below the sole, it is not visible. The sandal has improved fit through adjustability without compromising its appearance.
Example - Hook and loop adjustment with two straps
Figs 2 and 3 show more detail of the location of the adjustment means 200 relative to the heel of the example sandal. In this example, the first strap 210 includes a loop portion of a hook and loop fastener and the second strap 220 includes a hook portion of the fastener. The loops may be pulled to a desired length and then fastened together. The overlap of the straps is hidden below the sole.
Example - Hook and loop adjustment with a single strap
In another example, the two straps 210 and 220 may be portions of a single strap where one end the strap is fixed relative to the sole, and the other end of the strap can be adjusted with a buckle, a hook and loop device, or other adjustment device. One way to provide a single strap adjustment is to provide one portion of the hook and loop device on the end top portion of the strap, and to provide the other portion of the hook and loop device on the bottom top portion of the strap, such that the strap can be wrapped over a bar and fastened to itself. Example - Hook and loop adiustment with a multiple straps
In this example, more than two straps may be provided on the upper portion of the shoe, and the straps may be adjusted and fastened below the sole.
DESCRIPTION OF EMBODIMENT - Sandal with front strap adjustment positioned below sole
In one embodiment of the current invention, holes are provided in either the front or the back of the shoe in order to permit straps are ties to be routed below the sole.
DESCRIPTION OF EMBODIMENT - Sandal with hidden adjustment compartment
In one embodiment the current invention, a wedge-shaped heel is provided so that a compartment is created in the heel wedge in order to hide and protect the strap in the adjustment mechanism. This compartment may be covered or may be left uncovered.
DESCRIPTION OF EMBODIMENT - shoe with ties
In one embodiment of the current invention, the upper part of a shoe is tied to the foot by routing wide straps or strings through the sole and then securing the straps or strings to each other by tying them together.
DESCRIPTION OF EMBODIMENT - adjustable size shoe
In one embodiment of the current embodiment, an adjustable shoe is provided for children to permit the periodic adjustment of the size of the shoe as a child's foot grows. This approach is also useful for modifying the size of adult shoes as the adult's weight changes or has a swelling of a foot.
DESCRIPTION OF EMBODIMENT - removing excess strap
In this embodiment, the end portion of the straps are provided with markings or sections to permit excess strap to be cut and removed. For instance, in the case of a hook and loop fastener, the end portion may be sewn crosswise in several sections so that the strap may be cut just outside of one section. By sewing across the strap, the remaining portion is less likely to unravel. When using snaps, multiple snaps may be utilized with sections sewn in between to allow cutting with scissors.
