Description

TECHNICAL FIELD

Exemplary embodiments of the present invention relate generally to a cove base with a channel for receiving a sealant.

BACKGROUND AND SUMMARY OF THE INVENTION

Wall base is a trim item used for decorative and functional purposes. Wall base is typically positioned at the bottom of a wall where the wall meets the floor. The wall base provides a decorative element and also serves to cover the otherwise unsightly meeting of the wall and the floor. Sometimes, the wall base is secured to the wall by nails or other fasteners. Other times, the wall base is secured to the wall by way of an adhesive. In many cases, installation of the wall base results in various size and shape gaps between the wall base and the floor. Sometimes such gaps are caused by uneven floors. Other times, such gaps appear over time as the building shifts and settles.

An improper seal between the wall base and the wall or floor can be problematic in many environments. For example, without limitation, hospitals and other medical care facilities often treat patients who may expel bodily fluids on the floor. When cleaning, excess fluids may be inadvertently forced into such gaps between the wall base and the floor or wall. The lingering presence of fluids may promote the growth and release of bacteria and other germs into the surrounding environment. A similar experience may be found with restrooms. Even in more common applications such as but not limited to a home or business, moisture may leak into such gaps resulting in mold, bacteria growth, rust, and the like.

Sometimes a sealant may be provided on or around the wall base to further secure the wall base in position and/or to seal such gaps. However, it is difficult to provide the even and consistent bead of sealant along a wall base required to maintain an aesthetically pleasing appearance and proper seal. The terms “wall base”, “cove base”, “base moulding”, “base moulding strip”, etc., are but a few of the commercial terms used for such products, which are known to those of ordinary skill in the art of building construction and are used interchangeably herein to have the same general meaning. Often times, cove bases are comprised of a flexible type material, which makes the application of a sealant particularly difficult. To further complicate matters, cove bases may comprise a shoe portion which extends away from the wall to the floor and a bottom edge which contacts the floor. The addition of such features may make application of a sealant even more difficult.

Therefore, what is needed is a cove base with a channel for receiving a sealant. The present invention is cove base with a channel for receiving a sealant.

A portion of the cove base described as an elongate base member may be configured to extend along parallel to the wall when installed. Another portion described as a shoe protrusion may extend outward from the wall at an angle from the wall when installed. The shoe protrusion may be configured to extend downward and may include a radius angle which extends away from the wall. A heel may extend from the shoe protrusion and may be configured to contact the floor. The space between the heel portion, the shoe protrusion, and the floor may define a channel for the sealant when installed. The heel portion may be substantially cylindrical in shape, though any shape and size is contemplated. The heel portion may extend towards the base.

It may be desirable to form certain pieces of the cove base separately, such as to address manufacturing complexity issues and/or simplify installation. For example, portions of the cove base may be formed by an extrusion process and rolled into a large coil for convenient transportation and installation. In exemplary embodiments, the heel portion may be selectively attachable to the base member and/or the shoe protrusion. In this manner, the heel portion may be added to the cove base, such as prior to, during, or after installation of other portions of the cove base, such as the base member and shoe protrusion which may be separately formed. The heel portion may be separately formed, such as by an extrusion processes, coiled, and transported separately, for example. In such exemplary embodiments, the heel portion may be attachable to the base member and/or the shoe protrusion by way of one or more adhesives (glue, tape, combinations thereof, or the like), press fit, snap fit, tongue and groove, slot and mating protrusion, combinations thereof, or the like. Alternatively, or additionally, connection of the heel portion to the base member and/or the shoe protrusion may be accomplished by the sealant deposited within the channel.

Further features and advantages of the devices and systems disclosed herein, as well as the structure and operation of various aspects of the present disclosure, are described in detail below with reference to the accompanying figures.
