Description
BACKGROUND OF THE INVENTION
The invention relates to the field of plumbing apparatus wherein
bidet type flushing devices have usually taken the form of special
floor mounted bowls having built-in piping for discharging the
flushing water in an upwardly directed arc which was adjustable
only to the extent afforded by regulating the force of the flowing
water under control of valves mounted on the bowl. Such apparatus,
while of a more or less deluxe type, were expensive and
necessitated an additional floor mounted bowl in a bathroom already
occupied by a similar toilet bowl. Some of these prior floor
mounted bowls did not provide for a flowing stream of water but
merely provided valves and a drain closing arrangement which
enabled the bowl to be filled with water for hand washing
operations. This was not as sanitary as the flowing stream of water
and too, was expensive and occupied additional floor space. Some
prior art devices provided hoses and apparatus for use with the
usual toilet bowl but these were unsightly in a family bathroom and
did not contribute to the desired sanitary conditions.
OBJECTS OF THE INVENTION
It is the primary purpose of this invention to combine a bidet
flushing apparatus with a standard or typical bathroom toilet bowl
installation.
The principal object of the invention is the provision of a toilet
having a hinged seat which incorporates water lines or conduits and
flushing nozzles for bidet type flushing operations under complete
control of an occupant.
An important object of the invention is to provide a toilet seat
which incorporates bidet type flushing apparatus with controls for
regulating water flow and adjusting the discharge angle of flushing
nozzles.
Another object of the invention is the provision of a toilet seat
having bidet type flushing apparatus associated therewith and
having external controls operable by an occupant to regulate the
flow of water and adjust the angular positions of discharge
nozzles.
A further object of the invention is to provide a toilet seat
having front and rear bidet type flushing nozzles with externally
actuated controls for adjusting the angular position of either or
both nozzles.
A still further object of the invention comprehends the provisions
of a toilet seat incorporating bidet type flushing apparatus
including adjustable front and rear discharge nozzles with controls
means for adjusting the nozzles individually and for regulating the
flow of water to each nozzle.
Still another object of the invention is to provide a hinged toilet
seat incorporating a bidet type flushing apparatus with associated
external controls for regulating the flow of water through front
and rear discharge nozzles and for adjusting the respective
positions of the nozzles and wherein the flushing apparatus is
operatively connected to existing plumbing facilities through a
mixing valve to maintain the water through the discharge nozzles at
an even temperature.

SUMMARY OF THE INVENTION
This invention avoids the necessity for providing a separate bidet
bowl in the average bathroom but includes this facility without
requiring any additional space for the convenience of enjoying the
sanitary bathing apparatus. This device affords all of the
advantages of a special deluxe bowl type bidet but may be simply
and easily provided in the usual bathroom arrangement without
displacing any of the standard fixtures and without affecting the
normal operation of such facilities. The invention provides a
toilet seat which is interchangeable with the standard toilet seat
and which is hingedly mounted on the usual toilet bowl in place of
the original seat. The new toilet seat incorporates bidet flushing
apparatus built into the seat and generally concealed from view in
the normal use of the toilet. The bidet apparatus includes flushing
nozzles located both front and rear of the seat adapted to direct
the flow of flushing water in the direction of the center of the
toilet bowl but which are individually adjustable to vary the angle
of the discharged stream of water from the respective nozzles.
A control panel or bracket is provided outwardly of the toilet seat
and includes means for regulating each stream of water from the
respective flushing nozzles and for varying the positions of each
nozzle. This external bracket for the controls is provided as an
included element of the new toilet seat. The bidet flushing
apparatus is adapted to be operatively connected into the regular
bathroom plumbing system for obtaining hot and cold water through a
mixing valve adapted to provide a steady flow of flushing water at
the desired temperatures without variation of the temperature.
These plumbing connections are made without affecting the normal
supply of water to the other fixtures in the bathroom.
DESCRIPTION OF PREFERRED EMBODIMENT
In the drawings a replacement toilet seat is indicated at 10 and
which includes a hinged cover 11 as shown in FIG. 1. The toilet
seat and cover are illustrated as mounted on a typical toilet bowl
13 having the usual flush tank 14. The toilet seat 10 is hingedly
mounted on the toilet bowl 13 as by hinge means 15. The toilet 13
is of a more or less standard type and is shown as being located in
a bathroom 16 containing the usual facilities including a lavatory
17 having a cabinet enclosure 18 which conceals hot and cold water
supply pipes 19 and 20 that furnish water to the mixing faucet 21
on the lavatory. The supply pipes 19 and 20 each include a
T-connection 22 and 23 respectively and water lines 24 and 25 are
operatively connected into these T-connections with shut-off valves
26 and 27 in the respective lines. The water lines 24 and 25 supply
hot and cold water through a combined check valve and mixing valve
28 which maintains the flow of water from the respective water
lines without allowing either to dominate or flow back into the
other in the event that the pressure in one or the other of the
water lines should vary. The mixing valve 28 delivers the water to
a water line 29 which is comprised of a flexible material such as
rubber or neoprene or the like for a purpose hereinafter to
appear.
The toilet seat 10, as disclosed herein, is fabricated in two
pieces comprising an upper seat forming member 30 and a lower base
member 31. The two members, when secured together by cementing or
any other suitable means, comprise the complete toilet seat 10 and
while the present disclosure utilizes a two piece seat it is
contemplated that the toilet seat may be comprised of a single seat
member incorporating all of the features of the invention. As best
shown in FIGS. 11, 12 and 13, the upper seat forming member 30 is
provided with an underside that is hollow, as at 32, while the
lower base member 31 is provided with an upwardly opening groove 33
at one side of the central seat opening and which runs continuously
from front to rear of the base member between the front and rear
nozzle locations. The base member 31 is also provided with an
upwardly opening groove which is formed in three parts 34, 35 and
36 which are continuous and run along three sides of the seat base
member. The groove portion 34 extends across the front area of the
base member while the groove portion 35 extends from the groove 34
around the side area of the base member to connect with the groove
portion 36 which extends across the back portion of the base
member. When the upper seat member 30 is mounted on the base member
31 the grooves 34, 35 and 36 become covered over so that they are
fully enclosed.
The base member 31 and the seat member 30 are both formed with an
integrated bracket member 37 and 38 respectively which complement
each other when the upper and lower seat and base members are
secured together. The groove portion 36 extends continuously
through the bracket member 37. A conduit 39 for conducting water
into the toilet seat is mounted in the groove portion 36 and this
conduit is comprised of an inner pipe section 40 and an outer pipe
section 41. The inner pipe 40 at its inner end passes through the
wall of the outer pipe and terminates in a nozzle 42 located at the
rear of the toilet seat. Where the pipe 40 passes through the wall
of the outer pipe the joint around the pipe is soldered or brazed
to avoid any possibility of leakage.
The outer pipe 41 supplies water to a nozzle 43 located at the
front of the toilet seat and for this purpose a flexible tube 44,
which may be rubber or the like, is secured onto the end of the
pipe 41 by suitable clamp means as shown in FIG. 10 and this tube
extends through the groove portion 35 around the side of the base
member and is secured at its opposite end onto a pipe section 45
also by suitable clamping means. This pipe section is mounted in
the front groove portion 34 of the base member and the front nozzle
43 is mounted in this pipe section. Thus it will be seen that the
pipe 40 supplies water to the rear nozzle 42 and the pipe 41, tube
44 and pipe 45 supply water to the front nozzle 43.
The conduit 39, tube 44 and pipe 45 are free to rotate in the
respective grooves 36, 35 and 34 and the conduit 39, containing the
inner and outer pipes 40 and 41, is rigidly secured at its outer
end to a control panel member 46 containing appropriate valving to
supply a controlled flow of water into the conduit 39 from the
supply pipe 29. The control panel 46 being rigidly mounted with
respect to the inner and outer pipes 40 and 41 it will be seen that
when the control panel is pivoted about its axis, which is
coincident with axis of these pipes, the pipes will be rotated
therewith and therefore the rear nozzle 42 will simultaneously be
tilted or inclined upwardly at the rear of the toilet seat.
Means are provided for tilting the front nozzle 43 upwardly at the
same time as the rear nozzle and by the same pivotal motion of the
control panel 46 as best shown in FIG. 13. It will be seen here
that the pipe section 45 at the front of the toilet seat in the
groove portion 34 is provided with an upwardly extending lever arm
47 while the conduit 39 located in the groove portion 36 at the
rear of the toilet seat is provided with a downwardly extending
lever arm 48. These lever arms are operatively connected by a
mechanical link member 49 which is disposed in the groove portion
33. The link 49 is flexible but is designed to function both in
compression and in tension so that when the control panel 46 is
rotated upwardly the conduit structure 39 will be similarly rotated
to pivot the lever arm 48 in a counter-clockwise direction to move
the link 48 in a forward direction under compression against the
lever arm 47 to rotate the pipe section 45 in a clockwise
direction. Thus it will be seen as the conduit 39 is rotated
counter-clockwise and the pipe section 45 is simultaneously rotated
in a clockwise direction the rear nozzle 42 will be tilted upwardly
and the front nozzle at the same time will be inclined upwardly to
the same extent. The nozzles 42 and 43 normally are biased
downwardly and are adapted to be inclined upwardly only when the
control panel 46 is pivoted upwardly when operated by an occupant
of the toilet seat. A tension spring 50 suitably anchored at 51 in
the base member 31 is connected at is opposite end to the lever arm
48 and thus exerts a force on this arm to move it clockwise and
through the link 49 pulls the lever arm 47 counter-clockwise
whereby both of the nozzles 42 and 43 are lowered to the full line
positions illustrated in FIG. 11 where they are maintained
normally.
Adjustment of the front and rear flushing nozzles upwardly and
downwardly is obtained simultaneously by the occupants actuation of
the control panel 46 but the flow of water to the respective
nozzles may be had to either the front nozzle or to the rear nozzle
or to both nozzles simultaneously. Thus it is possible to utilize
only the front nozzle for flushing purposes or the rear nozzle may
be used alone or both nozzles may be caused to flush at the same
time. Reference is now made to FIGS. 5 through 8 for a full
disclosure of the control panel and valving arrangement for
regulating the flow of water to the nozzles 42 and 43. The water
supply line 29 connects into the control panel at 52 by means of a
fitting 53 to which the line 29 is secured by suitable clamping
means. Temperature of the incoming water is adjusted under the
control of the shut off valves 26 and 27 in the hot and cold water
lines ahead of the combined check valve and mixing valve 28 so that
the water entering the control panel is of the desired temperature
as selected by the user.
From the entering point 52 the incoming water is diverted through
passages 54 and 55 to spring loaded valves 56 and 57 which
communicate respectively with the inner pipe 40 leading to the rear
nozzle 42 and with the outer pipe 41 leading to the front nozzle
43. The water passages from the respective valves are indicated at
58 to the inner pipe 40 and at 59 to the outer pipe 41. The control
valves are spring loaded normally to close and shut off the flow of
water and are adapted to be actuated for admitting water to one or
the other or to both of the pipes 40 and 41 by control levers 60
and 61 pivotally mounted on the control panel. The levers 60 and 61
are substantially identical, the lever 60 being slightly longer
than lever 61 in order to position the finger button 62 further
forward than the finger button 63 on the lever 61 so that the user
can more readily identify and operate the separate controls for the
respective nozzles.
The lever 60 actuates valve 56 directing water through nozzle 42
when opened and the lever 61 actuates valve 57 to direct water
through the front nozzle 43 when that valve is opened. The finger
button 62 for the front nozzle, as indicated, is located in front
of finger button 63 on the control panel 46 for the ready
identification of the controls for actuation of the respective
nozzles whereby the user may quickly identify the finger button 63
for directing the flow of water through the rear nozzle 42 for that
type of flushing action and just as easily identify the finger
button 62 for directing the flow of water to the front nozzle 43
for front flushing action from that nozzle. The finger buttons 62
and 63 may be actuated simultaneously for causing the water to flow
through both of the front and rear nozzles 42 and 43 at the same
time for the combined flushing action obtained in this manner.
These various flushing actions are obtained while the control panel
46 is tilted at the same time by the user to obtain the desired
angle of the flushing nozzles to direct the streams of water for
the most effective washing actions.
As best shown in FIGS. 5 and 6, the actuating levers 60 and 61 pass
through the lower end of the respective valves and then the rear
end of each lever is pivotally mounted as at 65 in a bearing member
64 provided for that purpose on the underside of the control panel
46. The actuating levers, except for the portions thereof engaged
by the user to operate the flushing action, and the valve mechanism
are normally concealed by a removable cover 66 secured in place by
a screw 67. The valves 56 and 57 are spring loaded to close in a
downward direction so that an upward pressure on the respective
finger buttons 62 and 63 opens the valve for regulating the flow of
water under the control of the user and similarly an upwardly
directed force on the control panel 46 pivots that member about its
axis and thereby changes the angle of the flushing nozzles 42 and
43 in accordance with the desires of the user.
The valves 56 and 57, being spring loaded, shut off automatically
when the finger controls 62 and 63 are released by the operator.
These valves, of course, may be released one by one or
simultaneously and when released they have the effect of shutting
off the flow of water immediately. In the usual plumbing system
this would cause the "hammering" encountered when shutting off a
faucet or other valve controlling the flow of water. However, in
the present system of plumbing connections this pounding of the
plumbing is avoided. As previously described, the line 29
connecting this bidet toilet seat to the existing water lines is
made of rubber or neoprene or the like. When the valves 56 or 57
are released to shut off the flow of water to the flushing nozzles
a build-up of pressure occurs immediately but pounding of the
plumbing is avoided by the corresponding expansion of the resilient
line 29 afforded by the material of which the line is made. This
expansion occurs instantly upon the build-up of water pressure when
the valves are shut off and effectively prevent this objectionable
pounding which otherwise would be encountered under these
conditions.
From the foregoing it can readily be seen that a bidet type
flushing device has been provided which is incorporated into a
toilet seat that can be substituted for the usual toilet seat found
in the average bathroom and which provides a front flushing nozzle
as well as a rear flushing nozzle with control means for flowing
water through either nozzle to obtain a flushing action from either
direction as a separate flushing operation or from both directions
simultaneously to provide a combined flushing operation and wherein
the angle of the flowing water may be varied during the flushing
operation by changing the angle of the discharge nozzles under the
control of the user and wherein the controls for the flushing
action and the adjustment of the angularity of the flushing nozzles
are mounted on the bidet toilet seat.
