Description

RELATED APPLICATIONS

The present patent application claims the benefit of U.S. Provisional Application No. 62/560,098, filed Sep. 18, 2017, entitled “NEW ORTHOTIC DEVICE”, and further related to U.S. patent application Ser. No. 15/611,565, entitled OPTIONAL TWO PIECE SUPRA MALLEOLAR AND ANKLE FOOT ORTHOSIS SYSTEM AND METHOD THEREFOR, filed Jun. 1, 2017 both of which are incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present application generally relates to orthotic devices, and, more particularly, to a foot orthotic device having a detachable strap, the detachable strap allowing varus and/or valgus control of the mid-foot.

BACKGROUND

Foot orthotic devices are devices that may be placed within a shoe or other footwear to support a wearer's feet. Foot orthotic devices may be designed to correct an abnormal or irregular walking pattern, by altering slightly the angles at which the foot strikes a walking or running surface.
Orthotic devices typically consist of a shell that extends across all or a portion of the length of a shoe's insole. The shell may be used to support various parts of the wearer's foot such as, but not limited to the wearer's heel, arch, metatarsal area, and toes.
Most orthotics are formed of one or more layers of material having a uniform thickness the entire length thereof. Because known orthotic devices are typically formed with a uniform thickness, they do not provide enough support for portions of a foot requiring greater orthotic thickness. Further, known orthotic devices do not allow for the wearer to have varus and/or valgus control of the midfoot.
Therefore, it would be desirable to provide a device and method that overcomes the above. The orthotic devices do not allow for the wearer to have varus and/or valgus control of the midfoot.

BRIEF DESCRIPTION OF THE DRAWINGS

The present application is further detailed with respect to the following drawings. These figures are not intended to limit the scope of the present invention but rather illustrate certain attributes thereof.

FIG. 1 is a perspective view of an exemplary foot orthotic device according to one aspect of the present application; and

FIG. 2 is bottom view of the exemplary foot orthotic device of FIG. 1 with the strap removed and placed to the side in accordance with one aspect of the present application.

DESCRIPTION OF THE APPLICATION

The description set forth below in connection with the appended drawings is intended as a description of presently preferred embodiments of the disclosure and is not intended to represent the only forms in which the present disclosure can be constructed and/or utilized. The description sets forth the functions and the sequence of steps for constructing and operating the disclosure in connection with the illustrated embodiments. It is to be understood, however, that the same or equivalent functions and sequences can be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of this disclosure.
Embodiments of the exemplary foot orthotic device may be configured to enhance control of the midfoot of the wearer. The foot orthotic device may have a detachable strap which may provide varus and/or valgus control of the midfoot of the wearer.
Referring now to FIG. 1-FIG. 2 a foot orthotic device 10 (hereinafter device 10) may be shown. The device 10 may be formed of a customizable insole 12. The insole 12 may be customized to conform to a shape of a user's foot 30. A length of the insole 12 can be dependent on foot size and may extend from the user's heel 32 towards the front 34 of the foot 30.
The insole 12 may include a base layer 14 and an upper layer 16. The base layer 14 may extend from the back of the heel 32 of the user's foot past the arch 36 of the foot 30. The base layer 14 may be molded to conform to the bottom of the foot 30. The base layer 14 may be used to control the subtalar joint and foot biomechanics of the user. In general, the base layer 14 may be formed from a thin, firm material. For example, subortholen, polypropylene, copolymer, and carbon graphite composites may be used to form the base layer. The material forming the base layer 14 may be heated to allow the material to be malleable. Once heated, the base layer may be molded to conform to a shape of the bottom of the user's foot 30. Alternatively, the material forming the base layer 14 may be milled or formed via a 3D printer to conform to a shape of the bottom of the user's foot 30.
The base layer 14 may have a heel cup 18 formed on one end thereof. The heel cup 18 may be used to keep the heel 32 and hence the foot 30 from moving side to side. The heel cup 18 may further be used to elevate one side of the heel 32 to correct foot posture and gait. A medial longitudinal arch area 20 may be formed extending from the heel cup 18 along an inner side 14A of the base layer. The medial longitudinal arch area 20 may be used to support the arch 36 of the user's foot 30 and to redistribute the weight of the user to different areas to prevent excessive pressure. The medial longitudinal arch area 20 may also correct alignment issues.
A heel section 22 may be formed on a bottom section of the base layer 14 below the heel cup 18. The heel section 22 may slightly raise the area of the base layer 14 where the heel section 22 is located.
The upper layer 16 may be applied over the base layer 14. The upper layer 16 may extend past the base layer 14 to the end of the user's foot 30. The upper layer 16 may be formed of a flexible material. A foam, gel or similar material may be used for the upper layer 16. The upper layer 16 may provide a cushion to relieve any soreness, discomfort or the like in the foot 30.
The device 10 may have a strap 24. The strap 24 may be attached to the insole 12. As may be seen in FIG. 2, the strap 24 may be positioned in front of the heel section 20 and within the medial longitudinal arch area 18. In accordance with one embodiment, the strap 24 may be formed wherein a center area of the strap 24 is wider than the ends of the strap 24. This may allow for the strap 24 to have a greater surface area to secure to the bottom surface of the base layer 14.
The strap 24 may be permanently or removably attached to the bottom surface of the base layer 14. In accordance with the present embodiment shown, the strap 24 may be removably attached to a bottom surface of the base layer 14. As may be seen in FIG. 2, an attachment device 26 may be formed on bottom surface of the base layer 14. The attachment device 26 may be used to removably secure the strap 24 to the bottom surface of the base layer 14. A corresponding attachment device 28 may be formed in a center area of the strap 24. The attachment device 28 of the strap 24 may engage the attachment device 26 on the bottom surface of the base layer 14 to removably secure the strap 24 to the bottom surface of the base layer 14. In accordance with one embodiment, the attachment device 26 and the attachment device 28 may be hook and loop material or the like.
End attachment devices 29A and 29B may be formed on opposing ends of the strap 24. As may be seen in FIG. 2, the end attachments 29A and 29B may be formed on opposing side ends on the width of the strap 24. The end attachments 29A and 29B may be used to exert force to control movement of the foot 30. The straps 24 may go from medial to lateral, lateral to medial or both in order to control movement of the foot 30. The end attachments 29A and 29B may be attached in a crossing pattern over a top of the foot 30 and/or shoe of the user and below the malleoli 38 (ankle bone) of the user. The end attachments 29A and 29B may be attached in a crossing pattern such that the end attachments 29A and 29B may attached to opposing ends of the strap 24, to a shoe upon which the device 10 is placed, to soft extensions from the device or the like. The strap 24 may allow the user to have varus/valgus control of the midfoot of the user. Thus, one may exert more force either laterally, to counteract the foot 30 going in a supinatory movement outward and to the outside, or medially to counteract a pronatory movement inward and to the inside.
The foregoing description is illustrative of particular embodiments of the invention, but is not meant to be a limitation upon the practice thereof. The following claims, including all equivalents thereof, are intended to define the scope of the invention.
