Description
BACKGROUND OF THE INVENTION
This invention pertains to the general field of plumbing or toilet
fixtures. More particularly it pertains to devices for receiving
urine which are attached to flush toilets.
A search of the prior patent art reveals several attachments of
this general nature. The most pertinent art is believed to be in
U.S. Pat. No. 473,714 to M. Schubert, U.S. Pat. No. 2,100,774 to C.
T. dePuy et al., and U.S. Pat. No. 210,786 to T. C. Knight. All of
these represent efforts to solve the instant problem of preventing
the fouling of the toilet seat or peripheral areas. None of them
effectively prevent splashing. The Schubert and the Knight devices
are not readily adapted to a modern flush toilet. None of these
references disclose the self-rinsing or extendibility features of
the applicant's device.
SUMMARY OF THE INVENTION
The invention briefly comprises a funnel-like device adapted to be
mounted on the underside of a toilet seat and be raised and lowered
with said seat. The whole device is shaped to be positioned so that
if will fit within the rim of the toilet bowl and be substantially
out of sight when the toilet is closed. It is provided with a
funnel shaped receiver at the rising end in open communication with
a tubular duct member which follows the curvature of a side of the
seat and terminates with an outlet at a point generally below the
hinged portion of the seat and below the rim of the bowl,
preferably near the water level therein. The funnel end of the
device may te telescopically joined to the duct thus permitting
height adjustment for use by a standing person. Furthermore, either
end of the device may be shaped and positioned, with respect to the
flow of water in the bowl during flushing, so that it is
automatically rinsed.
DESCRIPTION OF THE DRAWINGS
FIG. I shows the front view of a toilet seat in raised position
with the urinal device attached. 1 indicates an easily releasable
fastener holding the funnel member 2 to the underside of the seat.
The dotted line 2' shows the funnel section in the extended
position. 3 shows means of securing the duct to the seat 5. 4 is
the telescoping section permitting extension of the funnel while
maintaining open communication to the duct 6. The duct is bent away
from the seat at 7 thus bringing the discharge opening 8 near the
water level. 11 and 12 show the beads which restrict or limit the
extension of the telescoping section 4.
FIG. II is a side elevation of the closed toilet showing the device
suspended from the seat and located inside the rim of the bowl.
Numbers 1 through 8, 11 and 12 have the same significance as in the
description of FIG. I. The toilet seat cover is at 9. 10 shows the
approximate source of water flow from the front of the rim which
may be received in the downward bulge of the funnel 2 for rinsings.
In its preferred form the terminal portion of the duct has a second
curve bringing the tip, 8 in FIG. II, to approximately parallel the
seat with the opening pointed in the direction of the stream of
water obtained during flushing with the seat down, thereby
effecting rinsing of the duct. 13 shows the approximate location of
the rear water inlet.
DETAILED DESCRIPTION
When the present toilets are used by males, there is inevitably
some splashing as the urine falls into the bowl. Even small amounts
escaping the bowl cause considerable contamination of the
surroundings with the resulting malodorous, unsanitary
condition.
The object of this invention is to provide for the elimination of
the splashing. This objective, and others, is achieved by this
invention which comprises a urine conveyer having a funnel-like
receiving end in open communication with an elongated discharge
duct adapted and curved to be mounted on the underside of a toilet
seat and substantially conforming to the curvature of either side
of the seat. The funnel or flared receiving end is adapted for
mounting under the rising portion of the seat. In this connection,
it should be noted that the funnel-like member is preferably of
off-set shape, not being circularly symetrical, in order that one
side of the funnel and the duct lie, at least approximately, in one
plane so as to fit against the underside of the seat. The discharge
duct follows the curvature of a side of the seat and terminates
with a discharge opening located below the rim of the bowl and
generally under the hinged portion of the seat. Although the
discharge end could be located below the water level, it is
preferably put above the water level to avoid being fouled by solid
waste.
The funnel and the discharge duct are positioned and curved
respectively to follow the curvature of a side of the seat and thus
are not generally in view when the seat is closed and do not
interfere with use of the toilet in the seated position. In case of
the open front or horse-shoe shaped seats the funnel is located
slightly off center as shown in FIG. I. When the seat is continuous
in the front, the funnel is preferably centered.
In addition to the non-splashing delivery of the urine to the bowl,
this invention provides for automatic rinsing of the funnel and
duct. Obviously, if the tube is not cleaned manually or otherwise,
it will develop an undesirable odor even though it is constructed
of smooth impervious plastic or ceramic. This rinsing may be
accomplished by one or both of two methods. For the more common
rear flushing toilets the discharge end of the duct may be curved
downward from the seat and then pointed toward the rear
approximately parallel with the seat so that, on flushing, with the
seat down as in FIG. II, the force of the water will reverse-flush
the duct.
In the case of the front flushing toilet the funnel end may be
located to intercept at least a portion of the water stream and be
more thoroughly rinsed when flushing with the seat down. Even with
rear flushing toilets, the funnel may be shaped and positioned to
be in close proximity with the inner surface of the bowl so as to
scoop up water during flushing, since most toilets provide a flow
of water from the rim throughout the periphery. Preferably, the
funnel is provided with a downward bulge, 2 in FIG. II which will
hold water until the seat is next raised whereupon the water will
flow through the duct when the seat is next raised.
The device of this invention may well be provided with all of these
rinsing features simultaneously. By virtue of this, the device
becomes suitable for mounting under the seat on toilets having
various bowl designs and flushing patterns and still retain the
rinsing feature. Furthermore, the conveyer may be mounted in a
corresponding manner on toilets having hinges either at the front
or the side.
As an added feature the funnel section and the duct section may be
separate pieces and telescopically joined to provide the necessary
open communication there between and to permit height adjustment of
the funnel for use. It may be telescoped at either a straight or
curved portion.
The means for adapting the conveyer to be mounted on the seat may
vary. The duct portion should not be perforated thereby. Such
fasteners may be spring clips or bands nailed, screwed, etc. to the
seat for example as shown at 3 in FIG. 1. Advantageously, the
funnel portion may be secured preferably at its upper edge, by a
releasable fastener which will keep it supported in the closed
position and permit easy extension for use. A hook and eye
arrangement would be satisfactory with either half thereof being
mounted on the edge of the funnel, for example, molded as an
integral part of the funnel member. Snap fasteners or magnetic
holders may also be used for both the duct and the funnel. Both the
funnel and the duct may have tabs, ears or fins integrally molded
thereon to facilitate mounting.
The material of construction may vary. Glass or ceramic could be
used but would require precision fitting to a given toilet. In this
respect a specific embodiment of the invention comprises the
combination of the urine conveyer herein described with the toilet
and would be considered a deluxe example of the concept. It is
preferable and more practical to construct the conveyer of a
semirigid material such as rubber, polyethylene, polyvinyl
chloride, and the like, since the device can be designed for
satisfactory mounting on most standard toilets.
As a further refinement the telescoping section may be provided
with a stop or restraining device to prevent accidental
disconnection thereof during use. Such a stop could be a nub or
ridge on the small section of the funnel positioned to engage a
mating stop mounted on the seat in a position to permit the desired
extension. Another means would be flexible restraint such as a
light chain or chord attached to the seat of the duct and to the
funnel with enough slack to permit the desired motion. Perhaps the
preferred means, shown at 11 and 12 in the figures comprises
cooperating beads mounted or moulded respectively on the outside of
the funnel tip and on the inside of the inlet end of the duct. When
the materials of construction are semi-rigid, the two parts may be
assembled after manufacture by forcing them together. If the
material is too rigid the bead on the inlet end of the duct may be
slipped over the tip of the funnel and secured, for example by
cementing or by threads after inserting the funnel.
The manner of using this invention is quite apparent from the
foregoing description. One hand is required to raise the seat while
adjusting the funnel with the other to the desired height ready for
use. While its use may be considered primarily for males it is not
limited thereto. For example, it would be useful for both sexes in
nursing homes where a patient may be ambulatory but could not rise
from a sitting position without aid. In this situation it might be
desirable to provide auxiliary means for adjusting and holding the
height of the seat. Such means could be a system of cord and
pulleys incorporating a counterweight adjusted to hold the seat in
a variety of positions. Alternately, a system of levers with weight
balancing or friction means for holding the seat may be used.
