The present invention relates generally to a cover for individual outdoor stairs and relates specifically to a unique way to shape and cover the stairs in order to reduce falls.
It can be appreciated that stair treads—including heated stair treads have been available for years in different varieties. However, all these devices are based on either a horizontal slope or one that leans such that fluid flows down the stairs. None of these devices slope the tread upwards to aid in footing. Many of them are invented with the aesthetic goal of covering up older, marked stairs in order to make them appear more attractive.
U.S. Pat. No. 893,198 to Schachner discloses a non-slip stair tread consisting of a metal surface.
U.S. Pat. No. 2,205,044 to Moore discloses a stair cover for stairs on transit vehicles. This invention utilizes a nosing to cover the screws which hold the tread in place.
U.S. Pat. No. 5,357,724 to Sonoda discloses one innovative stair tread that does utilize a rubber material. However the rubber encases a metal frame and it does not slope the tread upwards. The innovation is mainly concerned with rainwater drainage.
U.S. Pat. No. 6,082,061 to Ryan discloses a stair tread that utilizes plastic around a steel frame in order to provide a specific shape in steel with the protection of a plastic outer coating.
However, all of these above-mentioned prior art references, fail to provide a device that utilizes a combination of rubber-based, non-slip surface with innovative slope in order to help reduce incidence of falls.
It is an object of the present invention to provide a stair tread cover which overcome the drawbacks of the prior art.
This new rubberized object covers stairs in order to reduce falls. Specifically, the device alters the slope of the stair; the friction on top of the stair and the shape of the stair. Visibility, and hence safety, is also improved by bright coloring on the stair edge. Together these elements help reduce stair falls while still allowing for drainage. The unit may optionally be electrically heated via internal heating elements embedded in the material.
Turning now descriptively to the drawings, in which similar reference numbers denote similar elements throughout the several views, the attached figures illustrate an innovative stair tread cover.
