Bathtub protector
A bathtub protector includes a layer of protective material to cover at least the upper surfaces and front surface of a bathtub, and a layer of adhesive material on a surface of the protective material for adhering the protective material to a surface of the bathtub. The bathtub protector may include a central portion, which may be delineated by markings or perforations, which can be removed from the remainder of the tub and adhered to the bottom of the tub.
This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application Ser. No. 60/730,436, filed on Oct. 26, 2005, which is hereby incorporated by reference in its entirety.
BACKGROUND OF THE INVENTIONDuring construction of buildings and homes, it is. quite common for bathtubs to become damaged by construction workers' activities. The majority of damage is specific to the deck (top surface), apron (front surface) and the flat interior of the sump (tub bottom) This damage can include scratching, chipping, defacing, and paint or drywall mortar splattering on any of the tub surfaces. Accordingly, several tub protection products have been developed. These include spray on films which coat the surface of the tub, molded plastic in the shape of a tub often used to ship tubs to jobsites, heavy-duty cardboard or plywood scaffold systems designed to sit above the tub, and leather panels designed to surround the surface and walls of the tub. Although these devices protect the bathtub, they are not satisfactory.
Spray on foams and rubbers are not easily removed and often cause more harm than good as hours of labor are needed to remove the residual product left on the tub surface after use. Molded plastic protectors do not attach securely to the tub and their thin material is easily compromised. These protectors are commonly removed by workers, leaving the tub completely exposed, or worse, they allow nails to wedge between the protector and the tub surface, resulting in expensive repairs. Cardboard protectors cannot hold up to water and are too big, bulky and heavy to ship to be used regularly. Plywood scaffold systems are too big, heavy and require too much storage space for use in most production housing construction. Waterbased liquid coatings that cure after water evaporation are designed to be used with expensive airless sprayers for optimal application. This form of protection requires a time consuming 20 mil thick deposition to be used effectively and the manufacturers caution against getting the protection wet-an unavoidable fact of construction in a bathroom. The plastic protection described in U.S. Pat. No. 5,037,363 is meant to protect the tub during shipping and tub installation at an installation site. As it does not adhere to the tub, nails and construction debris are often allowed to fall between the protection and the tub finish. The protection is also often used for purposes other than intended; such as trash disposal or for use as a toilet. In many instances the protection must be removed before the drywaller or tile installer can begin work, leaving the tub open to damage during most of the construction process. The device described in U.S. Patent Application No. 2002/0178495 uses fitted leather panels that are secured together to form a single panel surrounding the tub. This protection is costly, too bulky to easily manage on a jobsite, and must be removed if tile is to be installed. Another drawback of this type of device is that it is not easy to ship to builders and requires a large amount of storage room to hold until used. The bathtub protection and work platform device of U.S. Patent Application No. 2003/0132062 works during some stages of construction or for small remodels, but is not practical for large scale production housing construction that would have an issue with storage of the platforms. Another reason platforms are not commonly used in production housing is that the fully covered tub does not allow either plumbers and/or tiling installers to perform all the aspects of their work.
BRIEF DESCRIPTION OF THE DRAWINGS
These problems are resolved in some embodiments of the invention by the design and step-wise method of protection. In one embodiment, early in the construction process, a solid rectangular protector is adhered to the exposed top (deck) and front (apron) surfaces of a tub using adhesive laminated to the bottom side of the protector. This first function for use in early construction protects the entire outside surface of the tub and creates a flat surface above the tub that is too thin to be used as a work platform and too thin to support weight for a standing platform. This prevents anyone from standing in the tub, and prevents any construction debris from becoming lodged between the protector and the bathtub surface. The adhesive backing makes installation easy and very quick.
Later in construction, the center area of the protector is cut with a scissors, exacto or drywall knife at the printed area above the bottom (sump) of the tub and pushed down to adhere the protection to the sump. The protector may also have perforations for ease in removing the printed area easily. This functionality allows other trades, such as drywallers and tile installers to stand in the tub while keeping the water resistant and puncture resistant protection beneath his or her shoes or boots.
Once removed, the cut-out central section could also be adhered to the upper surface of a piece of plywood that can be placed on the top of the protected tub deck to create a work platform. Adhering the cut-out portion of the protector to the plywood would render the covered area more water resistant and slip resistant than exposed plywood. The plywood could however just be placed directly on the protection if desired. The attached protection around the deck edge of the tub provides a safe layer of cushioning for the plywood to prevent scratching of the top tub surface from the plywood as the worker stands and moves on it. The protection is easy to manage on jobsites as it is simple to install, is lightweight and can be rolled to a small size for easy storage and handling.
An adhesive laminate on the underside of the device (not shown) could be exposed using a removable paper backing or could come pre-exposed. The protector 10 may also comprise flanges and tabs (not shown) in combination with adhesives in order to retain the protector 10 in place. The device could come as one piece or be made in two or more pieces, such as one piece fitting the top horizontal surface of the tub and a second piece fitting the front apron. In certain embodiments, the protector 10 may be colored, and may also be printed with information. In certain embodiments, the protector 10 may have anti-slip properties on its top surface, including adhesive, ridges of plastic, bumps or a no-skid surface decal.
Various embodiments may be of many lengths and widths to fit any size bathtub, or easily cut on site to the correct size. Embodiments may be manufactured for only one use as illustrated in
As the cover is placed over the bathtub, it preferably stops short of the wall edges, thus allowing the tub installer to complete the caulking in of the tub (if applicable), and may stay in place during the installation of wall board application. It also allows the tile installer to work with the protection in place later in the construction process. This can be seen, for example in

In the second step of use of the protection system, shown in
In one embodiment, use of the device may proceed as follows: First, wipe the bathtub free of dust and dirt, and unroll the protector. Place the protector carefully at the back comer of the bathtub aligning both the back and sides of the protector to the surrounding wall enclosure(s). In certain embodiments, as discussed above, a gap such as gap 24 of
