Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Application No. 62/360,506 filed on Jul. 11, 2016, which is incorporated in its entirety herein by reference.

FIELD OF THE INVENTION

The present invention relates to improved sandals, and in particular, to an improved sandal to provide greater support and comfort for the wearer.

BACKGROUND OF THE INVENTION

Footwear refers to garments worn on the feet, primarily for protection against the environment and for fashion. Many different styles and mindsets regarding footwear have existed over many centuries and across many cultures. Some ancient cultures such as the Egyptians, Hindu and Greeks did not regard footwear as an essential garment and often went barefoot, though the Egyptians and Hindus were known to occasionally don ornamental footwear, such as a sole-less sandal known as a “Cleopatra.” Other cultures, such as the Romans, considered footwear as visual signs of social and economic status and power, while going about barefoot was an indicator of poverty on the level of slaves and peasants.
Sandals are an open type of outdoor footwear, consisting of a sole held to the wearer's foot by straps passing over the instep and occasionally over the ankle. Sandals may take many different forms but the common understanding is that a sandal leaves a large portion of the upper foot exposed, particularly the toes. Conventional foot sandals ordinarily include a platform with straps extending across the platform and permanently secured within the platform structure. The foot is then slipped into the strap so as to provide a means of holding the foot to the platform. Sandals have been very popular for many years, and are widely used indoors and outdoors, usually in warmer weather and climates.

SUMMARY OF THE INVENTION

According to another embodiment of the present invention, there is disclosed an improved sandal to provide greater support and comfort for a foot of a wearer. The improved sandal includes a strap having first and second ends secured to a sole formed of at least one layer. Two or more thongs are attached at a first end to the strap between the first and second ends. The two or more thongs are attached at a second end to the sole.

The flip-flop sandal is typically designed for convenience and easy access in the application of inserting or removing the flip-flop footwear article on or off of the human foot. This is accomplished by inserting the forefoot portion of the human foot into the forefoot cover of the flip-flop wherein the forefoot cover of the flip-flop secures the forefoot portion of the user's foot to the forefoot section of the flip-flop's sole or foot bed. This as a result allows the heel portion of the user's foot to operate freely from the heel section of the flip-flop's sole. It is this design feature of the flip-flop that s great for convenience and leisure wearing.
The improved sandal 10 is designed to provide greater support and comfort for the wearer 12. Generally, the traditional flip-flop sandal incorporates a strap that holds the sandal on a wearer's foot 12 a, wherein the strap extends from the sole and is positioned so that fits between the first and second toes of the wearer. However, this design often leads to discomfort to the wearer. The improved sandal 10 is novel in that the strap 14 fits between several pairs of the wearer's toes and more securely holds the sandals to the wearer's foot. This is a safety feature and an improvement of the prior art sandals which tended to flop around leading to the wearer tripping and potentially hurting themselves. Another feature is that the improved sandal 10, while providing the comfort of prior art sandals, is better secured to the wearer's feet and is more attractive.
FIG. 1 illustrates a front three dimensional view of the improved sandal 10, having a strap 14 and sole 16 formed as is common in flip-flop sandals. The sole 16 may be made of a middle base layer known as the midsole 20, an upper surface layer known as the foot bed 22 and a bottom layer or outsole 24, as seen in FIG. 2. The foot bed 22 may be formed from rubber, leather, synthetic fabrics, or other materials that are known to the art. The midsole 20, foot bed 22, and outsole 24 may be constructed from the same material or a more durable material such as ethyl vinyl acetate (EVA), rubber, vulcanized rubber, polyurethane, dual density SSR, or any other material known to the art for sole construction. The upper surface layer or foot bed 22 may be adhered into or onto the middle base layer or midsole 20, and the midsole may be adhered into or onto the bottom layer or outsole 24.
The method of construction of the sole of the improved sandal 10 may vary depending on the design and various methods that are known within the art of flip-flop and sandal manufacturing. The upper surface layer or foot bed 22 of the improved sandal 10 may be formed so as to best fit the contours of the human foot. The foot bed 22 may be formed from the same or material as the midsole 20 or the outsole 24. In various embodiments of the present invention, the foot bed 22 may be altered or changed according to user comfort issues. Alternatively, the sole 16 may be one solid unit. In any of the above embodiments, the sole 16 may be made with any material and by any process known to the art.
As seen in FIGS. 1 and 3, the strap 14 includes two portions 14 c and 14 d which are attached to each other at one end 14 e and 14 f. The opposite ends 14 a and 14 b which are connected at one end to the intersection of the ends 14 e and 14 f of portions 14 c and 14 d, respectively, and at the opposite end 14 a and 14 b are secured to the sole 16 as described hereinafter. The strap 14 has at least first and second thongs 26 and 27 which are connected at one end 26 a and 27 a to the intersection of the ends 14 e and 14 f of portions 14 c and 14 d, respectively. The opposite ends 26 b and 27 b of the first and second thongs 26 and 27, respectively, are secured to the sole 16 as described hereinafter.
The first and second thongs 26 and 27 are positioned so that first thong 26 fits between the first and second toes 12 b and 12 c of the wearer, and second thong 27 fits between the second and third toes 12 c and 12 d of the wearer 12. Although there are two thongs 26 and 27 illustrated in the present embodiment, there may be up to two additional thongs to secure the other toes of the wearer.
As seen in FIG. 2, each of the first and second thongs 26 and 27 have post base 28 and 29, respectively, which are disposed in openings 31 and 33 extending from the foot bed 22, through the midsole 20 to the outsole 24. The ends of the first and second thongs 26 and 27 are formed into circular post base 26 a and 27 a which are secured in openings 31 a and 33 a formed in the outer facing side 24 of the sole 16. The openings 31 a and 33 a are larger in diameter than openings 31 and 33 so that the two thongs 26 and 27 remain secured to the sole 16. The strap 14 and the thongs 26 and 27 may be integrally formed. Alternatively, strap 14 and the thongs 26 and 27 may be suitably attached and fixed in any desired fashion.
FIG. 2 illustrates the manner in which the strap 14 is attached to the sole 16. Each of the first and second thongs 26 and 27 has a post base 28 and 29, respectively embedded in the sole 16. Further, first and second ends 14 a and 14 b of the strap 14 has a post base 32 a and 32 b similar to post base 28 and 29, secured in the openings 37 and 39 which are larger in diameter than openings 41 and 43 extending from the foot bed 22, through the mid sole 20 to the outsole 24 so that the two straps sections 14 c and 14 d lain secured to the sole 16.
FIG. 4 illustrates the improved sandal 10 in use on a wearer's foot 12 a. As illustrated, the thong 26 a is lodged between the first and second toes 12 b and 12 c of the wearer, and thong 26 b fits between the second and third toes 12 c and 12 d of the wearer 12. As previously mentioned, the improved sandal 10 may have additional thongs (not shown) to fit between the other toes of the wearer's foot 12 a, such as third and fourth toes 12 d and 12 e, respectively.
Although the invention has been shown and described with respect to a certain preferred embodiment or embodiments, certain equivalent alterations and modifications will occur to others skilled in the art upon the reading and understanding of this specification and the annexed drawings. In particular regard to the various functions performed by the above described components (assemblies, devices, etc.) the terms (including a reference to a “means”) used to describe such components are intended to correspond, unless otherwise indicated, to any component which performs the specified function of the described component (i.e., that is functionally equivalent), even though not structurally equivalent to the disclosed structure which performs the function in the herein illustrated exemplary embodiments of the invention.
