Description
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 feet- receiving
horizontal portion 22B 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
22B 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 22B 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 22B 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 many arrangements 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 22B or, if
desired, may extend his feet directly across to be supported on the
seat-height 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-receiving bottom portion 22B 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 22B 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
that it 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. It 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.
