Description

FIELD OF THE INVENTION

This invention relates to improved methods and apparatus concerning shoehorns.

BACKGROUND OF THE INVENTION

Shoehorns are generally used to make putting on shoes easier. Long handled shoehorns are used by persons who present with limitation of range of motion of their back, hips, knees, or even ankles, and are not able to reach their feet to put on their shoes. Known long handled shoehorns are used as an enabler which allows a person to insert his feet into his shoes without having to bend over.
Long handled shoehorns that are known and available in the market are straight with a hook handle. When using the prior art, a person with limited joint range of motion may need a separate assistance device such as a reacher to pick up his shoe to position it next to his foot. After inserting the shoehorn next to the counter of the shoe, the person needs to rock the shoehorn forward and backward slightly, while pushing his heel down, to help guide the foot as it slides into the shoe. This forward and backward movement of the shoehorn may be limited by contact with the person's calf and thigh. A person's hand or fingers may even get pinched between the person's lower leg/calf and the shoehorn as the individual pushes their heel down. The known long handled shoehorns, such as for example, as shown in U.S. Pat. No. 3,501,073 to Breithor, U.S. Design Pat. No. D508303 to Bradley, U.S. Design Pat. No. D302,490 to Denney, U.S. Design Pat. No. D427,417 to Israel, U.S. Pat. No. 7,337,933 to Klinberg, and U.S. Pat. No. 6,695,182 to Shrewsbury may be difficult to use for an individual with multiple joint restrictions, and when there is limitation of motion in a person's upper extremities, such as in their shoulders, elbows, wrist or hands in addition to limitation of motion in their lower extremities and back. This is usually the case with the elderly and persons who have undergone major orthopedic surgery involving different joints in the body. The complex limitation of their joints sometimes necessitates another person to steady the shoe while the individual tries to get their foot in the shoe.
The previous straight shoehorn devices create little space between the person's heel and the back of the person's shoe. If the shoe is tight it is usually uncomfortable using the prior art when the person's heel presses against the bottom and side edges of the shoehorn.

SUMMARY OF THE INVENTION

One or more embodiments of the present invention will enable an individual to put on their shoes without bending over. It improves the quality of life of persons with physical disability or limitation by increasing their level of independence in performing this task/activity of daily living.
One or more embodiments of the present invention provide a shoehorn which is configured to be shaped like the angle of a human ankle and may be used to hold the tongue of a shoe, such as a sneaker, in place while a person is trying to put his forefoot into the shoe. At least one embodiment of the present invention can be used as a simple tool to reach and pick up the shoe and position a shoe next to a person's foot in case the person is unable to reach for his shoe. The angled design, in one or more embodiments also does not interfere with the person's lower leg and/or calf and eliminates the need to rock the shoehorn forward and backward to make room for the persons heel as it slides into the shoe. The person is free to maneuver his heel into the shoe without getting his hand or fingers caught between his calf and the shoehorn.
