Description

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to a device for protecting the knees, legs, ankles, and feet of a person spending time on their knees or in a kneeling position.

2. Background of Invention

The present invention is useful to those who spend periods of time on their knees or in a kneeling position, such as tile layers or gardeners.

The device allows a user to spend greater periods of time on their knees or in a kneeling position while reducing pain, discomfort, strain and damage on the user's body from the neck down. The device accomplishes this by providing an angle and support where the leg rests and by distributing that weight along the user's legs, knee, shin, ankle, and foot more evenly than devices taught by the prior act. This increases the total surface contact of the user with the floor and the support device thereby decreasing the pressure per square inch the user experiences in contact with the floor.

The device may be in a form that is adjustable to fit persons with varying leg lengths and sizes as well as persons with different foot sizes and foot lengths.

The device may also include feet on either or both ends of the device, said feet may be made of material that reduces friction between the device and the surface the device is resting on, allowing the user of the device to freely slide around on the surface on which the device is resting without having to stand and exit the device. Additionally, the optional feet on either or both ends of the device may be of a material that will prevent the device from scratching the surface on which the device is being used.

Also, the portion of the device that receives the user's legs and shins may be made of a soft material, cushion, or pad, or may be made of a material that has been or is capable of being molded to the user's legs. This leg receiving portion of the device may be concave, rounded, or otherwise shaped or molded.

Presently, persons spending time on their knees or in a kneeling position have few options for protecting their knees, legs, ankles, and feet. These options do not adequately, protect the user's knees, legs, ankles, and feet, and are more cumbersome to use than the present invention.

It would therefore be desirable to enhance the effectiveness of devices for allowing persons to spend extended periods of time on their knees or in a kneeling position.

There remains a need for a device that reduces the strain placed on the feet, ankles, knees, back, neck, and legs of persons who spend periods of time on their knees or in a kneeling position. The present invention fulfills this objective, as well as other needs and objectives, as will be apparent from the following description of the present invention.

SUMMARY OF THE INVENTION

In accordance with one aspect of the invention, a device for protecting knees, legs, ankles, and feet is provided. The device comprises a frame made of one or more pieces of material. The pieces of the frame may be made of either a single piece or multiple pieces of material, connected to each other at their terminal ends with their connecting piece or segment.

In accordance with another aspect of the invention, the frame is bent to form and angle on the frame, which angle is between 0 degrees and 180 degrees. The degree of the angle and its location in the frame maybe made variable to provide for multiple frame geometries, allowing for a more customized fit for different users. Further, the degree of the angle maybe adjustable by the user.

In accordance with another aspect of the invention, the overall length of the frame maybe adjustable, allowing for a more customized fit for different users. Further, the device may in the user's foot.

In accordance with another aspect of the invention, the space in the interior of the frame maybe filled with a soft material, pad, or cushion, or a material capable of being molded to multiple forms to create a more customized fit for the user, or may have a pre-molded surface, or solid surface that may or may not be molded.

In accordance with yet another aspect of the invention, the frame has two or more feet surfaces that contact the working surface and which may be of a material designed to reduce friction between the device and the surface it is placed upon, allowing for easier movement of the device over the surface by the user. These feet may also be made of a material that will reduce or eliminate scratching of the surface upon which the device is used.

The present device provides for an improved method of protecting the feet, ankles, legs, back, neck, and knees of persons who spend periods of time on their knees or in a kneeling position, which overcomes the above-referenced and others.

One advantage of the present invention is that the user has less strain placed in their feet, ankles, and knees while on their knees or in a kneeling position. The device distributes the body weight of the user over the full length of the user's leg, minimizing the pressure per square inch the user feels in contact with the floor.

Still further advantages of the present invention will become apparent of those of ordinary skill in the art upon reading and understanding the following detailed description of the preferred embodiments.
