The present invention relates to footwear and more particularly to a reusable pedicure protection system, that, prevents damage to injured, painted or treated toenails. It consists of an insert and a shoe with a certain shape and size. The insert, which is comprised of a cover and base, can be worn with or without shoes. The described shoe differs from a standard shoe, as it consists of an expandable toe box area that accommodates the insert. When the shoe is not in its expanded form, it has the size and fit of a standard shoe, and therefore can be worn like a standard or regular shoe. The user of the footwear or device (insert with or without the shoe), has the freedom to walk about indoors or the outdoors while their toenails are drying. The device is particularly useful when flip-flops or any other footwear that permit toenails to be exposed cannot be worn. The device prevents physical contact between the toenails with any other surface. The device is especially useful when obtaining a pedicure and the necessary time required for toenail drying is not available or when protecting damaged or medically treated toes.
People frequent manicure and pedicure salons as part of their beauty regimen, often having their nails painted as part of the treatment. After the application of nail polish, considerable time is typically spent under the nail dryer to ensure that the polish dries and doesn't smudge when the nails come into contact with other objects. For a pedicure, the toenail dryer reduces the likelihood of smudging or damage when the toenails come into physical contact with shoes or other objects. When the dryer, however, is not used for the required amount of time an appropriate means is necessary to maintain the integrity of the treatment after leaving the salon. People who do their toenails at home also face a similar challenge of protecting their pedicure from smudging. Some options to protect treated toenails or damaged toes are available, however, these have significant disadvantages. These options include:
As a solution to the challenges mentioned above, devices have been proposed to address the issue of wearing closed toe shoes without smudging painted or treated toenails. Some examples include U.S. Pat. No. 7,296,367 B2 to Kipnes; U.S. Pat. No. 7,134,225 B2 to Ashton; U.S. Pat. No. 7,421,807 B2 to Condie; U.S. Pat. No. 7,681,332 B2 to Allen, US Patent Publication US 2010/0263237 A1 to Cuellar, and U.S. Pat. No. 5,946,823 to Yates. They are all variants of a design concept for a shoe with a removable toe covering which in theory never touches the user's toes. These structures have certain disadvantages such as:
In the area of shoe inserts, other proposed devices appear to address pedicure protection and medical foot problems, including but not limited to post operative recovery, correction of toe alignment, and bunions. However, they lack the structural elements that would make them suitable as an insert that prevents smudging of toenail polish applied on the user's toe. One such example is the insert device disclosed in U.S. Pat. No. 4,745,927 to Pecorella, used for toe alignment, which consists of just a base and no cover. The Pecorella insert provides no protection for the toenails and given that the base consist of a semi-rigid material, there isn't an obvious means of attaching, to the insert, a cover with a more rigid structure that can open and close for multiple cycles. Even if a cover were added to this device, there is no structural element, which would prevent the cover from touching the user's toenails. Another problematic component of this structure is the strap around the large toe that keeps the toe in contact with the base. Due to the shape of the base under and around the anchored big toe, which includes a narrower width at the toenail (distal end of phalanx) than at the big toe's knuckle (joint of the distal and proximal phalanx) and the slit in the base on the inner side of the large toe, the strap may easily slip up the toe and onto the toenail. This movement of the toe strap may not be of concern if the device is used as a toe straightener, however, it could smudge the toenail polish.
Another device is a variant of a toe covering apparatus, US Patent Publication US2003/0213149 A1 to Woods. The Woods' device is an external attachment to an open toe surgical boot, made to protect the wearer's toes. It is specifically designed for use with an open toe boot, where there is no limit to the size of the space cavity created around the toes. The Woods device is not designed to be used as an insert in a closed type of shoe and therefore is not constructed to allow the wearer's foot to slip into and out of a shoe. In Woods' device, the toecap can be a molded shape, with a cover, base and sides. The cover and base cannot be physically separated from each other as there is no hinge joint and, in fact, the cover and base are designed and shaped as a one piece mold. The toecap is removed as a whole, that is, both the cover and base act as one piece, since there is no hinge or living hinge between the cover and the base. A living hinge is a thin flexible hinge made of the same materials as the two ridge pieces it connects. The living hinge is typically thinned or cut to allow the pieces to bend along the line of the hinge. In iteration, the toe covering is a flat shape, which can be folded into a shape with a top, bottom, and sides, attached to each other by interlocking flaps. For a flat shape capable of bending and to stay in the folded position, the material would necessarily need to be quite soft and malleable. Hence, with application of pressure the desired shaped cannot be maintained. The combined application of pressure and the absence of a support structure to reinforce the space between the toe and the cover would result in the cover coming into contact with the surface of the toes, and thus making it ineffective as a pedicure protector. The molded version cannot open and close and the flat version cannot maintain a rigid shape. In the flat version, the area where it bends is not a living hinge, the material bends because it is soft and flexible.
Additionally, in the Woods' device, the sides as well as the top and base are an integral component of the insert. The sides of the toe cover, especially when made from a molded inflexible material, can cause friction where the outer sides of the big toe, and the smallest toe meet the sides of the toe cover, leading to discomfort. This would especially be enhanced if the user has corns, bunions or any affliction that causes swelling or protrusion along the sides.
The same or similar limitation exists with Cuellar (US2010/0263237 A1), which consists of a rigid toecap that encapsulates the toes on the top, the front and the sides. While there may be a space cavity between the top of the toes and the cover, there isn't one specified for the sides of the foot. Friction between the outer sides of the first and last toe is also more likely due to the existence of separators between the toes, which spread the toes further apart.
Cuellar's device also details an external removable protective cover, which is attached to the shoe by an arch shaped band containing magnets. A detachable covering can be lost and render the shoe useless as a pedicure protector. The band across the instep as described in Cuellar is specified to maintain a non adjustable arched shape, which coincides with the shape of the toe covering and 1) therefore must be made of rigid material and 2) would not change with the size of the user's instep or foot in general, posing a problem with the fit. This differs from the elastic band across the instep for the device outlined in this application, because it is made of elastic and therefore adjusts with the user's foot. The rigid band in Cuellar also has a different structure and use to the one described in this application. Cuellar's device is rigid and keeps the cover attached to the shoe, while the device in this application contains a soft and flexible elastic band that adjusts to the wearer's foot size and keeps the cover closed.
Tornetta U.S. Ser. No. 13/196,473 describes a device to protect pedicures, in which there is a main body and cover that are totally and separately detachable. The important characteristics of Tornetta's device are that: (i) the device covers the front, top and the sides of the foot; (ii) the upper surface (cover) and main body (base), are attached by a plurality of extrusion edges found in both the surface and main body and that correspond to each other; and (iii) loop separators that stabilize the toes to the main body, and have elastic properties. One limitation of this device is that the foot is encased within the protector with a rigid cover. Therefore, depending on the width of the user's foot, if too wide, would result in friction between the outer sides of the big toe and the smallest toe and the surface. Another limitation is that the surface is totally detachable and removable and can easily be misplaced. The other important limitation is that while the loop separators may have elastic properties, there is no means of adjusting the tension, which would be problematic in maintaining the proper toe positioning.
Another footwear device detailed as a shoe but also with an insert version is described in Heid US2009/0113759 A1, which details therapeutic footwear for repositioning of the great toe and/or spreading the wearer's toes. The Heid device appears to be for certain therapeutic purposes and is not designed to protect the toes from contacting other surfaces, the insert version consists of only a base, and not a cover. Inserts comprised of just a base can easily fit into conventional footwear, which would be the case for the Heid device. For an insert with a rigid cover, the space provided around the toe area of the shoe must be adequate, which in a conventional shoe, isn't the case. One cannot therefore simply add a rigid covering to Heid's device, for example as seen in the Woods' device. Heid's device is described as a shoe itself and not an insert. The idea of adding a cover to the Heid insert is not described or disclosed. Rather, the cover described is part of the shoe and not a part of the insert itself.
In light of the limitations and disadvantages mentioned in the previous patents:
(a) One object of the invention is to provide a device that protects the user's toes from physical contact with other surfaces thus protecting damaged or treated toes.
(b) Another object of the invention is to provide a pedicure protection system that allows the user to wear shoes shortly after a pedicure without damage to painted or treated toenails.
(c) Yet another object of the invention is to provide a pedicure protection system that is worn directly on the foot and enables the user to walk about comfortably, both indoors and outdoors.
(d) A further object of the invention is to provide a pedicure protection system comprised of an insert, which gives the user the flexibility to wear a variety of weather appropriate shoes or no shoes at all.
(e) A yet further object of the invention is to provide a pedicure protection system that limits movement of the toes thereby preventing contact with the device's surface when the user is in motion.
(f) Another further object of the invention is to provide a pedicure protection system that can be easily cleaned.
(g) A yet another further object of the invention is to provide a pedicure protection system that can be made in a variety of sizes and out of material that is durable yet comfortable on the skin.
Other advantages of the invention will become apparent from the ensuing description and accompanying drawings. In accordance with one embodiment, the pedicure protection device is composed of an insert that encompasses and is worn directly on the forefoot. The insert is composed of two pieces that may be connected by a hinge. The cover is designed to open and close at the hinge without touching the toenails. Straps that run across the big toe, the adjacent second toe and the elastic band over the instep, anchor the foot to the base and allow the user to walk comfortably. The curved shape of the cover 13 above the toenails creates a cavity separating the toes from the cover. A protruding separator extends upwards between the big toe and the adjacent second toe to support the cover against downward pressures. This helps to maintain the space cavity between the toenails and the cover. The elastic band across the instep also serves to keep the cover closed. The material used to make the cover and base will be thin due to the limited space in a shoe, but rigid so that it maintains its shape. As this device is not a part of or attached to a shoe, the user can optionally wear the device as a shoe insert, or walk around comfortably without shoes. It can be worn either with regular shoes with the necessary space in the toe cavity, or with the shoes with an expandable toe box.

Described herein is a foot device designed to protect injured, painted or treated toenails from damage through contact with other objects. The device is comprised of an insert covering the foot from the toes to the ball of the foot. That is, the length of the device or insert is from the toes to near the level, or the beginning, of the arch of the foot. In this specification, another name for the beginning of the foot arch is also known as the instep of the foot.
The embodiment, as illustrated in
The cover 10, is rigid and molded into a curved shape 38 that creates a cavity,
In this embodiment, as shown in
In
In the preferred embodiments the device has a toe separator 18 is located between the big toe and the adjacent second toe that exceeds the height of each of the user's toes. In other embodiments, toe separators can be placed between some or all of the toes or there may be no separators (
In many of the embodiments, the left and right edges of the base contain two holes, slits or apertures 19 that allows the passage of an elastic band 20. These slits, apertures or openings completely penetrate the base and allow the elastic band to pass through for anchoring the device. The elastic band helps to keep the cover closed and the device secured to the user's foot. The band can be made of material other than elastic, can be adjustable and may also consist as a continuous piece of material (that is, as one continuous band encompassing the device). For this type of embodiment, on either side of the cover are cutouts creating two protruding edges or tabs or anchoring flaps 14. The band 20 is placed under the protruding edges or tabs as shown in
In an alternative embodiment, the device may have no elastic band, 20 and the cover may be kept closed through a system of attachments between the cover and base, including but not limited, to Velcro material as shown
Although the insert can be used with any shoe, the shoe as seen in
In use, this pedicure protection system is provided in pairs, and is designed to be worn on the left and right foot. Although the following description and illustrations are directed primarily to the right foot pedicure protection system, it should be understood that the discussion is equally relevant to the left foot pedicure protection system. The purpose of the embodiments is to act as a protection device, that is placed on the foot before, during or after the application of toenail polish or toe treatment. The insert device is a separate entity from the shoe, and can be worn in a variety of shoes to protect a pedicure treatment from smudging or undoing any type of toe treatment.
During the pedicure process, the user wears the device, such as the embodiment illustrated in
In the diagrammatic or schematic view of the preferred embodiment as shown in
After toenail polish is applied, the user can also place their feet under the nail dryer while wearing the device. The hinge 12 or other type of attachment pivotally allows the cover to bend back far enough so that the foot can fit under a dryer unencumbered. The heat resistant plastic allows the user to sit under the dryer without the device getting too hot and causing skin discomfort. After the pedicure, the user can close the cover and secure the device to the foot with the band 20, for this particular embodiment, and can walk around with the device. Alternatively, the user may decide to use shoes and they can then protect their pedicure by wearing the device as shown in the embodiment of
The design of this footwear or device provides the user with a pedicure protection device that can be worn interchangeably with any shoes and at any point during the treatment. The disclosed invention is not limited to the specific embodiments described, as many other forms or type of embodiments are possible with the device or combination of insert and shoe.
