MAGNETIZED APRON ASSEMBLY
The present invention relates generally to structures for enclosing bathing fixtures, such as bathtubs, whirlpools and showers. More particularly, it relates to an apron assembly comprising a frame member and an access panel that are held together through magnetic means.
The present invention relates generally to structures for enclosing bathing fixtures, such as bathtubs, whirlpools and showers. More particularly, it relates to a novel apron assembly that is suitable for attachment thereto.
BACKGROUND OF THE INVENTIONConventional bathtubs are provided with front panels or aprons that are not detachable. In order to make the plumbing connections for the tub after the tub is in place, access thereto must be provided through a door or opening in a wall against which the tub abuts. This same door is necessary for making repairs. Whirlpool spas and showers often have the same limitations as showers.
Aprons (also referred to herein as “apron assemblies”) for bathtubs and whirlpools are commonly used to give a finished look to a bathtub or whirlpool. They provide access, when needed, to equipment such as pumps, motors, piping and other operating equipment located behind the apron. A problem can arise when installing aprons and securing them to the bathing fixture. Traditional means that are used to install aprons include bolts and clips, and these can weaken the aprons over time and otherwise damage them. They can also make removal of apron assemblies difficult when it is necessary to gain access to the operating equipment.
Representative apron assemblies are shown in the following patents and patent publications: U.S. Pat. No. 2,528,432; U.S. Pat. No. 3,028,603; U.S. Pat. No. 5,864,898; U.S. Pat. No. 5,940,906; U.S. Pat. No. 6,363,546; U.S. Pat. No. 7,278,175; United States Patent Publication No. 2007/033,728; French Patent Application No. 2,529,070; and French Patent No. 2,614,927. The apron assemblies shown in these patents are either kept in place with clips, screws, bolts or through a “snap” fit of some kind.
It is also known in the art to use tiles to cover one or more sides of an enclosure that includes a bathtub or whirlpool. Due to the popularity of this kind of bathing equipment, various solutions have been provided over the years to provide access to the plumbing and other operating equipment to minimize if not prevent breakage of the tile enclosure. Frequently, one or a few select tiles are movably positioned against a portion of a side wall of the bathing enclosure so as to allow access to the operating equipment. The selected tiles can be attached in a variety of ways, including clips, brackets and even magnets to avoid breakage of the tiles. Representative patents and patent applications that are relevant here include the following: English Patent No. 1, 322,782; French Patent No. 795,505; French Patent No. 1,255,461; French Patent Application No. 2,354,320; French Patent Application No. 2,614,927; French Patent Application No. 2,857,397; German Patent No. 2 308 502; German Patent No. 203 04 886; German Patent No. 40 09 921; German Patent No. 31 38 153; and German Patent No. 33 02 042.
The present invention seeks to overcome some of the limitations of aprons and other enclosure types that are currently available for baths, whirlpools and showers.
SUMMARY OF THE INVENTIONIn one embodiment, the present invention provides an apron assembly for a bathing fixture that includes a tub having an outwardly extending rim. This apron assembly includes a frame member having at least two opposing open sections with a central supporting portion in between and an access panel. It is constructed and arranged to be positioned in front of a side wall of the tub. The frame member contacts the rim adjacent an upper portion of the frame member and is secured in place through regular fixation means, as known to those in the art. The access panel is sized to fit within the frame member.
Conveniently, the frame member and access panel of the apron assembly are connected through the use of magnets. These magnets may be positioned either on the outer surfaces of the frame member and access panels, or can be included within the material that is used to construct the apron assembly.
Contact between the magnetic elements need not be direct. If the magnetic field is strong enough, the access panel may be placed between the separate magnetic components.
The use of magnets in lieu of traditional mechanical means confers several advantages. First, it does not cause damage to either the frame member or the access panel. Second, the access panel can be more readily removed without risk of breakage. Third, the overall appearance of the bathtub can be improved due to the fact that the magnetic elements are concealed from view.
The particular aspects and features of the present invention will become apparent to those of ordinary skill in the art upon review of the following description of specific embodiments of the invention, in conjunction with the accompanying figures.
Embodiments of the present invention will now be described, by way of example only, with reference to the attached Figures wherein:
The novelty of the present invention resides in the positioning of one or more magnetic elements within an apron assembly. These magnets replace more traditional fixation means that are used for bathtubs, whirlpools and showers, such as bolts and clips. Advantageously, the use of magnets minimizes damage to the apron assembly and facilitates removal of the access panel for maintenance and repairs.
Turning now more particularly to
The choice of magnetic elements will depend on the material that has been chosen to make the access panel. Generally, any magnet that has the strength to keep the access panel affixed to the frame member would be acceptable. Combinations of magnets of different sizes and strengths may be selected for assembly and are within the purview of one of skill in the art. Examples include, without limitation, rare earth magnets (including Samarium Cobalt (SmCo) magnets, a second generation of rare earth magnet material), neodymium magnets (such as neodymium iron boron (NdFeB) magnets), Cast Alnico and Sintered Alnico magnets, (which are aluminum nickel-cobalt-iron alloys), and hard ferrite magnets (ceramic magnets composed of barium or strontium).
The above-described embodiments of the invention are intended to be examples only. Variations, alterations and modifications can be made to the particular embodiments described herein by those of skill in the art without departing from the scope of the invention.
