Description

BACKGROUND OF THE INVENTION

The present invention relates to limb support devices. More specifically, the present invention provides an adjustable portable foot elevator for comfortably supporting an individual's foot in an elevated position.

Many medical procedures performed on the foot, ankle, knee, or other part of the leg require long recovery periods. It is often recommended that individuals elevate the foot in a raised position during recovery. This reduces swelling of the injured area and assists with the healing process. It can be difficult to elevate a foot in a raised position with an ineffective support. For examples, some individuals utilize a stack of pillows to elevate an injured foot. However, the foot is prone to slide off of the pillows, which may cause additional injury.

Individuals with lower back pain may also benefit from maintaining their leg in a raised position. However, it can be difficult to determine an exact elevation at which to maintain the foot for optimal comfort. The exact position may change over time depending on other factors such as the location and intensity of the pain experienced. In order to address these concerns, the present invention provides a vertically adjustable portable foot elevator having a cushion with a recessed portion configured to receive the heel portion of a foot.

Devices have been disclosed in the prior art that relate to limb support devices. These include devices that have been patented that generally relate to foot and limb supports, such as U.S. Pat. No. 7,669,934, U.S. Pat. No. 8,408,652, U.S. Pat. No. 8,616,652, U.S. Pat. No. 6,935,697, and U.S. Pat. No. 6,935,992.

These prior art devices have several known drawbacks. These devices fail to provide an adjustable foot rest for supporting a single foot wherein a recessed portion of the foot rest receives the heel portion of the foot. Further, the prior art devices fail to provide a planar base having a plurality of legs extending downward therefrom. There is a need in the art for an adjustable foot elevator which is portable so that an individual may elevate the foot in different locations and sitting positions.

In light of the devices disclosed in the prior art, it is submitted that the present invention substantially diverges in design elements from the prior art and consequently it is clear that there is a need in the art for an improvement to existing foot support devices. In this regard the instant invention substantially fulfills these needs by providing an adjustable portable foot elevator.
