The present invention relates to decorative grab bar assemblies, particularly those suitable for use in showering areas.
Grab bars are sometimes located within or near bathtubs, shower enclosures and other plumbing fixtures such as toilets to assist persons (e.g. especially the elderly or handicapped) in entering into, sitting upon, or standing for prolonged periods at, such plumbing fixtures. Typically they are mounted on a room or enclosure wall, often directly to framing studs. See e.g. U.S. Pat. Nos. 2,242,461, 3,098,240 and 7,124,451.
Conventional grab rails are tubular and metallic, and thus are highly institutional in appearance. Some homeowners are reluctant to install them (notwithstanding their benefits) because of this. Apart from poor aesthetics, some homeowners may not want visitors to know that they need special assistance in moving relative to plumbing fixtures.
Hence, some companies have tried to incorporate grab rails into more hidden alcoves, so that they are not as immediately noticeable. See e.g. U.S. Pat. No. 5,577,275. However, these rails are typically very short and may not fully meet the need for a rail along a broader expanse of the fixture.
Further, some have tried to partially hide the rail under shields. See e.g. U.S. Pat. No. 5,377,525. However, this has led to undesirable increased costs of manufacturing, assembly and maintenance.
Also, the most traditional metallic materials for such rails can require more frequent cleaning than typical shower area walls do.
Thus, a need exists for improvements with respect to grab rail assemblies, particularly those assemblies suitable to be used in a decorative showering environment.
The present invention provides a grab bar assembly mountable along a wall. It has an elongated rail positionable on the wall, the rail having an upwardly open recess to facilitate gripping of the rail, and a frontal facade. There is also a decorative layer (e.g. decorative tiles) mounted on the frontal facade.
The wall could be a portion of a showering area. Alternatively, it could be another wall of a bathroom, or even a wall of a mud room or the like. In any event, it is particularly desirable for the wall on which the grab rail is to be mounted to be a tiled wall.
Hence, the frontal facade can be in a form of a tile holder, and the decorative layer can be in a form of a plurality of tiles positioned in the tile holder. Also, the rail can have a wall mount and a grip wall.
Most preferably the grip wall has the frontal facade and also has an upper grip section, there is a drain formed between the wall mount and the grip wall, the wall mount and grip wall are made from extruded aluminum, there is at least one drainage spacer between the wall mount and the grip wall that in part defines the drain, and there is a channel formed in the wall mount that is configured to direct fluid from the channel to the drain. There can also be a spacer between the facade and the decorative layer.
In another aspect of the invention, there can be a grab bar assembly mountable along a wall of a showering area. It has an elongated rail positionable on the wall, the rail having an upwardly open recess to facilitate gripping of the rail, wherein the rail also has a wall mount and a grip wall. There is also a drain formed between the wall mount and the grip wall to permit water entering the upwardly open recess to drain out from the upwardly open recess behind the grip wall. Preferably there is also a drainage spacer between the wall mount and the grip wall.
In yet another form of the invention there is provided an assembled showering area. It has framing, a tiled shower positioned within an area defined by the framing, a stud rail coupled to the framing, and a grab bar assembly of the above type coupled to the stud rail.
It will be appreciated that the present invention permits most of the visible surface of the rail to be made of the same material as the surrounding environment (e.g. identical tiles). Thus, grab rail assemblies of the present invention ornamentally can meld with the aesthetics of the remainder of the enclosure and do not appear institutional in nature.
Importantly, they achieve the secure gripping function without permitting water to collect long term in the rail. This helps minimize the possibility of mold development. Further, they provide a variety of alternative ornamental accessorizing options.
These advantages are achieved at reasonable cost. Hence, they can be implemented as a practical matter.
These and still other advantages of the present invention will be apparent from the detailed description and drawings. What follows is merely a preferred example embodiment of the present invention. The claims should be referenced to assess the full scope of the invention.
The example embodiment is described below in relation to a showering area 10. However, the present invention can be used with other walls such as a tiled wall of a bathroom adjacent a toilet, or a tiled mud room wall where one typically removes outdoor shoes before entering the house.
As shown in
A shower head (not shown) supplies water to the showering area 10 in the usual fashion. A floor drain 24 extends through the floor 20 to allow water to drain from the showering area 10 when the showering area 10 is in use. Tiles 26 are affixed to the walls 14, 16, 18, floor 20, and ceiling 22 in a conventional manner (e.g., mortar, mastic, resin, or similar bonding method). Alternatively, the walls 14, 16, 18, floor 20, and ceiling 22 may be fiberglass or any other suitable material and construction.
Turning next to
The stud rail 28 extends substantially horizontal with respect to the floor 20 of the showering area 10 along the left side wall 16 and the back side wall 14. The grab bar assembly 12 may be mounted on all, two adjacent, or just one of the walls 14, 16 and 18. There is also a ledge portion 32 of the support rail that can be supported, in part, by the floor 20 via legs 34.
The grab bar assembly 12 is shown mounted to the framing 30 in
The grip wall 40 is also secured to the stud rail 28 via fasteners 38. The grip wall 40 is configured to be grasped by users at a top and is also coupled to the framing 30.
The wall mount 36 and grip wall 40 are mitered at an interface formed between the back wall 14 and the left wall 16 to create a mitered joint 44 establishing a uniform transition. In the example embodiment, an end cap 46 (shown in
The end cap 46 prevents forward leakage from the rail. The end cap 46 may be covered by tile, or the end cap 46 may remain exposed. Alternatively, the end cap 46 may take on a variety of configurations to establish a smooth aesthetic transition. A bead of silicone (or the like) can be applied at the junction of the wall mount 36, grip wall 40, and the end cap 46 to prevent water from passing by the end cap 46. Additional sealing may be used to prevent water from flowing between the walls 14/16 to waterproof the mitered joint 44.
The wall mount 36 and grip wall 40 are preferably formed of extruded aluminum. However, a variety of other materials may be used.
It is of note that many of the mounting holes and openings are preferably created “on site” so that the installation of the grab bar assembly 12 can be tailored to each particular installation application. In any event, the wall mount 36 may include an upper mounting strip 48 having a plurality of openings 50 through which the fasteners 38 pass to secure the wall mount 36 to the framing 30.
A horizontal ledge 52 extends inward from the mounting strip 48 to help support and align a substrate 54 and the tiles 26 that are ultimately secured to the substrate 54. A bottom surface 58 of the wall mount includes L-shaped standoffs 35 that rest along the stud rail 28.
An upper surface 60 defines in part the J-shaped channel 42 that directs water within the grab bar assembly 12 away from the walls 14, 16 of the showering area 10. A lip 62 extends downward from the channel 42 to help direct water towards the floor drain 24. As one skilled in the art will recognize, a variety of cross-sections may be used for the wall mount 36 and the grip wall 40. For example, the wall mount 36 may not have the standoffs 35, but may instead be a boxed channel having a lower surface that rests atop the stud rail 28.
The preferred grip wall 40 includes an upper handle or grip portion 64 and a lower facade 66. The upper handle or grip portion 64 is preferably contoured to receive a user's hand. For example, as shown in
The facade 66 defines a generally C-shaped recess 72 in the form of a holder having an upper lip 73 and lower lip 71 for ultimately receiving inlays 25, such as tile, laminate, wood, metal, and the like. It is of note that the recess 72 need not have defined upper and lower bounds, but instead may merely provide a mounting surface for an inlay 25. Additionally, the depth of the recess 72 may be altered depending on the desired aesthetics of the grab bar assembly 12.
In the example embodiment, the recess 72 includes several longitudinal ribs 75 that extend the length of the grip wall 40. The ribs 75 help establish a sturdy bond between the grip wall 40 and the inlays 25.
Particularly importantly, the preferred grip rails include a structure to prevent water from the shower collecting on a long-term basis in the channel 42. The grip wall 40 is spaced apart from the wall mount 36 by a series of drainage spacers 76 that are sandwiched between a vertical portion 78 of the lip 62 and an inner surface 80 of the grip wall 40. A series of drains 82 are therefore defined between the wall mount 36 and the grip wall 40 (between the spacers) such that as water enters into the channel 42 it is directed to the drains 82 to ultimately flow to the floor drain 24.
The drainage spacers 76 are preferably extruded aluminum structures that include an opening 84 to receive a fastener 38, thereby securing it in place. The drainage spacers 76 may be produced from any suitable material (e.g., rubber, plastic, metal, ceramic, and the like), provided a substantially rigid coupling between the grip wall 40 and the wall mount 36 is achieved.
It should now be appreciated that facade 66 is configurable to receive a variety of materials that may be used to better aesthetically integrate the grab bar assembly 12 with the surrounding showering area 10. For example, if the tile 26 of most of the enclosure has a particular nature or appearance, that same tile can cover over most of the grip rail assembly. Further, this largely synchronizes the cleaning need of the grip rail assembly to that of the shower enclosure as a whole.
With particular reference to
The assembly and integration of the grab bar assembly 12 is shown best in
The grip wall 40 is then secured to the stud rail 28 via a series of fasteners 38 that extend through holes 94 formed in the recess 72. The fasteners 38 pass into the holes 94 in the grip wall 40, through the openings 84 formed in the drainage spacers 76, and through a series of openings 96 formed in the vertical portion 78 of the lip 62, to extend into the stud rail 28. Thus, the grip wall 40 helps secure the wall mount 36 to the stud rail 28, and ultimately, the framing 30.
With specific reference to
A series of inlays 25 are affixed to the facade 66 by an adhesive 55 (and the like). Given the thicknesses of the tiles 26 and any particular substrate 54, the depth of the ledge 52 and or recess 72 may be adjusted to achieve a flush appearance between the tiles 26 and the wall mount 36 to establish an integrated appearance of the grab bar assembly 12.
In order to accommodate inlays 25 having a variety of thicknesses, a plurality of spacers 81 (shown in dashed lines in
While the example embodiment described includes separate drainage spacers 76 and tile spacers 86, either or both of these structures, may be integrally formed in the wall mount 36 and/or grip wall 40. For example, the wall mount 36 or grip wall 40 may include a series of standoffs (not shown) that act as drainage spacers 76 to define the drain 82 when the wall mount 36 and grip wall 40 are coupled. In addition, the tile spacers 86 may be formed integrally with the grip wall 40 where the ultimate thickness of the substrate 54 and tiles 26 are known.
Preferred example embodiments of the present invention have been described in considerable detail. Many modifications and variations of the preferred example embodiment described will be apparent to a person of ordinary skill in the art. Therefore, the invention should not be limited to the example embodiments described.
The invention provides a grip rail assembly for installation on a wall such as a wall of a showering area, particularly where the assembly aesthetically melds with the surrounding environment and avoids collecting water within the grab rail.
