Bell, Jr. Assistant ExaminerDonald B. Massenberg Attorney-Head & Johnson [57] ABSTRACT A bathtub affording improved safety, especially for the elderly or handicapped, including an opened top tub, the bottom of which has a seat-height horizontal portion extending from one end of the tub and a lower feet-receiving horizontal portion, one wall of the tub having a door opening extending from the top of the tub to the lower feet receiving portion of the tub bottom and the upper portion of the opening being of a width sufficient to expose part of the bottom seatheight horizontal portion, and a door pivotally supported to the tub so that, when the door is in opened position, a user may walk onto the bottom lower feet receiving portion or sit on the exposed part of the bottom seat-height horizontal portion, the door when closed permitting the tub to be filled with water to the height desired.

2 Claims, 2 Drawing Figures BATIITUB HAVING IMPROVED SAFETY FOR INFIRM OR HANDICAPPED BACKGROUND, SUMMARY, AND OBJECTS OF THE INVENTION One of the most difficult aspects of caring for an elderly, infirm, or handicapped person is that of bathing. The typical bathtub in use. today sits on the floor with vertical upstanding sidewalls. The user must step over a wall of the tub and then sit down into the tub. While the procedure is completely safe for a normal person it is extremely difficult for the. physically limited or infirm. In addition, the chance of slippage on the tub bottom while getting into and out of the tub is always a danger.

To reduce the danger inherent with the typical bathtub the provision of a door in a raised bathtub has been suggested. U.S. Pat. No. 3,066,316, L. E. Russell, inventor, issued December 4, 1962, and the references cited, illustrates this improved type of tub. The arrangement of the bathtub of this previously issued patent affords greatly improved safety over the commonly used bathtub for handicapped and infirmed. The present disclosure relates to an improvement in the bathtub of the type shown in U.S. Pat. No. 3,066,316. Particularly, the present invention provides a bathtub having a door in one sidewall thereof which permits the user to either walk directly into the tub without having to step over a sidewall or, if desirable, to sit directly into the tub. The door of the tub may then be closed and the tub filled with water to the height desired.

It is therefore a general object of this invention to provide a bathtub having improved safety for elderly, infirm, or handicapped.

.More particularly, an object of this invention is to provide a bathtub having a door therein permitting the user to step directly into the tub without having to step over a sidewall.

Another object of this invention is to provide a bathtub having a door in one sidewall thereof permitting the user to either step directly into the tub without having to step over a-sidewall or to sit directly into the tub at chair-height level.

These objects as well as more specific objects of the invention will be fulfilled by the bathtub described in the following specification and claims, taken in conjunction with the attached drawings.

DESCRIPTION OF VIEWS FIG. 1 is an isometric view of a bathtub embodying the principles of this invention, the tub having a door in one wall thereof, the door being shown in closed position.

FIG 2 is an isometric view as in FIG. 1 but showing the door in opened position.

DETAILED DESCRIPTION Referring to FIGS. 1 and 2, a bathtub embodying the principles of this invention is illustrated, it being understood that the actual appearance of a tub having the invention as a portion thereof may depart in many ways from the example illustrated. The tub is generally indicated by the numeral 10 and includes a back sidewall 12, a front sidewall 14, a first end wall 16, and a second end wall 18..The height of the walls 12-18 are greater than those of the normal bathtub and may be, as an example, approximately twice the height of the normal bathtub.

The tub bottom includes a first seat-height horizontal portion 22A extending from first end wall 16, a lower 2 feetreceiving horizontal portion 228 and a second horizontal seat-height portion 22C extending from second end wall 18. The horizontal seat-height portion 22C is connected with the horizontal feet-receiving portion 228 by a bottom vertical portion 22D. In the same manner the first horizontal seat-height portion 22A is joined to the horizontal feet-receiving portion 223 by a vertical wall 22E hidden from view in the drawings. The bottom portions 22D and 22E are described as being vertical and this expression is used in a general sense as such portions may be slightly declined from the vertical portion 22D shown in the drawings.

A door opening 20 formed in front sidewall 14 includes a lower portion 20A which extends to the bottom feet-receiving portion 22B. This enables the user of the tub to step directly onto bottom portion 228 without stepping over a sidewall. The upper portion 20B of door opening 20 is of a width sufficient to expose a part of the bottom seat-height horizontal portion 22A. This enables a user to sit directly onto a horizontal portion 22A at chair-height level.

A door 24 is configured to fully close opening 20. The door is pivotally supported to the front sidewall 14 by means of hinges 26 and is held in closed water-tight or water sealing position by means of a latch 28. The particular type or configuration of the hinges 26 and latch 28 is not a portion of this invention as these may take a variety of types and arrangements. In addition, the specific means of sealing door 24" to the door opening 20 is not a part of the invention since manyarrangements exist for effecting a leakproof seal.

At second end wall 18 plumbing fixtures are shown, indicated by the numeral 30. Such is not necessarily a part of the invention. In some plumbing arrangements the fixtures are not part of the bathtub but are located above the tub for discharging water downwardly and into the tub and either arrangement would be within the scope of this disclosure.

The invention provides an arrangement for a bathtub having advantages over other known types of tubs. With door 24 opened the user can step directly into the tub without stepping over a wall as is required in using the normal bathtub. If more convenient the user may sit directly onto seat horizontal bottom portion 22A. This is particularly important for infirm or handicapped people who must move from a wheelchair to the tub. By this arrangement the elevation of the person does not have to change in going from a wheelchair to the tub.

With the user inside the tub the door 24 can then be closed. The user may keep his feet extending downwardly into the lower feet-receiving portion provided by the lower bottom 228 or, if desired, may extend his feet directly across to be supported on the seatheight portion 22C. In the drawings the separation between the horizontal portion 22A and 22C is shown to be relatively large, however, this is a matter of design and if desired the width of the feet-receivingbottom portion 228 may be only that minimum required to enable a person to place his feet comfortably therein. If

bottom portions 22D and 22E are more vertical than illustrated the width between the horizontal portion 22A and 22C would be much less than they would appear in the figures. The existence of the downwardly extending recess provided by the lower feet-receiving horizontal bottom portion 228 will not interfere with the normal use of the tub since a person sitting in a bathtub usually has his knees raised slightly. Another advantage of the tub of this invention is thatit provides a convenient means for affording a foot bath for those who may not wish to bathe completely and is therefore highly useful to those people having foot problems requiring often foot bathing.

While the invention has been described with a certain degree of particularity it is manifest that many changes may be made in the details of construction and the arrangement of components without departing from the spirit and scope of this disclosure. is understood that this invention is not limited to the specific embodiments illustrated and described herein for purposes of exemplification, but is to be limited only by the scope of the attached claim or claims, including the full range of equivalency to which each element thereof is entitled.
