The present invention generally relates to bathtubs and bathtub/shower combinations that satisfies the needs of impaired persons who find the use of a conventional bathtub difficult, if not impossible.
Typical bathtubs have raised walls that a bather must step over, thus making access thereto difficult or impossible for many disabled bathers.
Walk-in bathtubs are becoming increasingly common in hospitals, nursing homes, and most recently private homes.
In addition to safety, the ease of entering a bathtub by way of a door additionally provides bathers independence thus enabling bathing without the assistance of another person when getting into and out of the bathtub.
Unfortunately, such bathtubs typically require more space for doors, tracks, lifts, and other components than is available in typical bathrooms. In addition, the size of such units prohibits retrofitting or installation into an existing bathroom, without removal and replacement of walls, doors, or windows.
The present invention provides for modular easy access bathing enclosure which is preferably dimensioned to be comparable to a full-size, or soak-bath type bathtub, and yet capable of being installed in a typical bathroom either as a new installation or as a retrofit.
A modular easy access bathing enclosure in accordance with the present invention generally includes a shell having a bathing area with an arcuate sidewall including an access opening extending from a shell top to an opening bottom, an arcuate sliding door is provided for enclosing the access opening, as well as gaskets for sealing and locking the door in the access opening.
In one embodiment, the door is slideable adjacent the sidewall and in another embodiment the door is slideable within the sidewall for supporting the door.
More particularly, a modular easy access bathing enclosure in accordance with the present invention generally includes a shell having a seating area and a standing area with a contiguous sidewall. The sidewall around the standing area includes an access opening extending from a top of the shell to a point proximate the standing area.
A pocket door is provided for enclosing the access opening and is movable into or adjacent to a sidewall surrounding the standing area for enabling entry into the bathing enclosure by a bather. Inflatable gaskets provide for both sealing and locking the door in the access opening.
In a preferred embodiment, the sidewall has a parabolic surface of revolution (PSR) shape around the standing area and the PSR shape extends outwardly from the standing area. This provides for more “elbow room” for a bather standing on the standing area. In this instance the pocket door also has a PSR shape and, when closing the access opening, a “teacup” shape is provided for the bather.
More particularly, a track is disposed adjacent to or within the sidewall around the standing area for supporting the door and a drain is provided at a bottom of the shell along with the drain valve.
A frame is provided for supporting the shell, and front and side panels are also provided for enclosing the frame. The front panel may be generally planar and includes a cutout for alignment with the shell access opening and in a preferred embodiment the pocket door extends outwardly from the front panel, when sealing the access opening, due to the PSR shape thereof.
This modular arrangement enables on-site assembly and importantly passage through a conventional doorway, thus eliminating the need for undesired tear-out of existing bathroom walls, doors, or windows in order to install the bathing enclosure in accordance with the present invention.
For both safety and convenience, a door handrail is disposed proximate a door top for facilitating opening and closing of the door and assistance in steadying an unstable bather. In addition, a shell handrail is provided which is disposed proximate the shell top, which includes a piston, disposed therein. The piston is connected to the door handrail for hydraulically opening and closing the door thus providing independent operation for an impaired bather lacking strength or mobility for operation of the door.
A top front panel, top side panels, and a top door panel may be provided which are attachable, respectively to the front panel, side panels, and door, for providing a showering area for the bather.
Still more particularly, the standing area may be for the most part, generally circular and the drain is disposed proximately center of the standing area. In order to provide a level standing area, a removable grate may be provided for covering the standing area. The grate enables water passage therethrough and may include a plurality of support ribs on an underside thereof for stabilizing the grate on the standing area.
In one embodiment of the present invention, some of the support ribs may be hollow and communication with holes in the grate and an air supply for causing bubbling in a water filled shell.
In addition, the seating area may be elevated from the standing area and interconnected by a seat wall enabling a seated bather to have a heel position directly below a seat edge thus facilitating standing of the bather from a seated position.
The advantages and features of the present invention will be better understood by the following description when considered in conjunction with the accompanying drawings in which:
With reference to
Importantly, the shell 14, frame 42, and panels 46, 48, 50 are all fabricated for onsite assembly and passage through a conventional doorway such as, for example, but not limited to a 34-inch wide doorway (not shown). The shell 14, frame 42, and panels 46, 48, 50 may be formed from any conventional material including but not limited to gel-coated fiberglass, or acrylics.
The modular nature of the enclosure 10 enables the use of fascias 46 of various designs to be utilized in order to match or compliment various bathroom decors. In addition, the fascias may be removed at any time to facilitate access to workings, pump lines, etc., not shown, for bath installation and repair. In addition, a separate opening 54 may be provided for maintenance or repair.
As shown in
As best shown in
The use of a pocket door 66 enables a wider access opening 32 to be utilized than would otherwise be possible with a hinged door, not shown.
A door rail 70 fixed to the pocket door 66 in any conventional manner facilitates opening and closing of the door 66. In addition, the door rail 70 provides a structural bridge across the access opening 32 when closed.
The door 66 may be manually open and closed by the rail 70; however, preferably a shell hand rail 72 is disposed in a conventional manner proximate the shell top 36 which includes a piston 76 disposed therein, see
With reference to
A conventional drain 92 with a drain valve 94, operable in any conventional manner, is disposed at a bottom 98 of the shell 14 and best seen in
Hydraulics, including water filling and draining of the enclosure 10, may be done in any conventional manner and not described herein for the sake of clarity.
To provide bubbling in the water (not shown) within the shell 14, as illustrated by air flow arrows 102 in
Referring to
With reference to
The gasket 130 is preferably hydraulic and also provides for locking of the door 66 in the access opening 32. When filled with water, the gasket 130 is effectively solid and movement is prevented between the door 66 and fillings 124, 126, 128.
With specific reference to
With reference to
The enclosure 150 is substantially identical to the enclosure 10 except that the access door 66 is supported by a track 154 between an inside wall 158 and an outside wall 160 of a sidewall 164. Alternatively, the outside wall 160 may be eliminated with the door 66 being supported adjacent the wall 164 on an outside thereof by the track 154. Further features of the enclosure 150 are identical to the features of the enclosure 10 hereinabove described.
Although there has been hereinabove described a specific modular easy access bathing enclosure in accordance with the present invention for the purpose of illustrating the manner in which the invention may be used to advantage, it should be appreciated that the invention is not limited thereto. That is, the present invention may suitably comprise, consist of, or consist essentially of the recited elements. Further, the invention illustratively disclosed herein suitably may be practiced in the absence of any element which is not specifically disclosed herein. Accordingly, any and all modifications, variations or equivalent arrangements which may occur to those skilled in the art, should be considered to be within the scope of the present invention as defined in the appended claims.
