Description
TECHNICAL FIELD
[0001] This invention relates to a type of a stoppered discharge
system which is designed for toilet reservoir and performs its
function with various water volumes.
BACKGROUND ART
[0002] Stoppered discharge systems have been used in reservoirs for
a long time. There is a need to decrease the amount of water
consumed in toilets due to reduced water sources and the methods
for fulfilling this need include for example discharge systems with
reservoirs of 3-6 liters, toilets which function with less than 6
liters of water or stoppered discharge systems. Therefore user is
able to stop the system by intervening water flow after required
amount of water is run or enough cleaning is done.
[0003] Discharge systems located in reservoir are used in different
types for each reservoir trade mark and model. In prior art, in
European patent No: EP0892117 an example of stoppered discharge
system is illustrated. In this patent, to perform full discharge or
discharge in desired amount, elements with magnetic character are
used on floating part attached to overflow tube and on the surface
in which this part is seated. System of European patent No:
EP0892117 which emphasizes on sealing character comprises complex
and expensive parts in terms of manufacturing. In European patent
No: EP1270831 a reservoir system with double discharge valve is
disclosed. In operation, main valve remains opened by the aid of
water pressure inside reservoir and second valve controls the
amount of water to be added to reservoir by means of at least one
floating part. Full discharge and partial discharge could be
provided with main valve. The object of European patent No:
EP1270831 is to perform operation with less closing noise and with
less required force.
[0004] In broadly speaking, advantages of stoppered discharge
system of the invention used in reservoir are a special formed
discharge bearing with double O-ring, a lantern having fingers
hereon which could be attached to discharge bearing and a discharge
bearing support. In virtue of these structural features,
utilization, mounting and maintenance ease could be provided with
stoppered discharge placed in reservoir due to its structure and
this could be used as a discharge with long-life.
OBJECT OF THE INVENTION
[0005] The object of this invention is to achieve a stoppered
discharge system which is easily mounted on toilet reservoirs,
robust, able to operate with various water volumes and such that a
user could discharge any amount of water he/she desired.

channels (33) located at cylindrical region (38) on discharge
bearing. Discharge bearing (1) is placed into exit channel of
reservoir from cylindrical region (38) and is also placed in lower
interior surface of reservoir due to rabbetted structure of sitting
surface (39) in discharge bearing (1). In stoppered discharge
system (A), during discharge, water in reservoir is used by passing
from water passage channel (35) into discharge channel (34). The
position of lantern (3) is fixed by engaging lantern fingers (41)
of lantern (3) shown in FIG. 6 into bearing locks (36) at both
sides of discharge bearing (1). The task of two sealing gaskets (2)
is to prevent any leaking from discharge bearing (1) in reservoir
even if all support or fixing parts of stoppered discharge system

at lower side hereof is located where two segments (11) and
discharge gasket (12) in between are placed top of each other. Two
longitudinal discharge tube corrugations (72) extending as opposed
which fit in lantern upper opening channels (44) are located in
discharge tube middle portion (77). Two longitudinal discharge tube
styrofoam corrugations (76) extending as opposed on styrofoam
engagement surface (74) formed by diameter attenuation relative to
discharge tube middle portion (77) are located between
segment-gasket sitting surface (75) and discharge tube middle
portion (77). The rabbet at which discharge tube middle portion
(77) finishes and styrofoam engagement surface (74) starts, is
styrofoam clip abutment rabbet (73) where styrofoam clip (9) shown
in FIG. 11 is fitted. The job of discharge gasket (12) attached on
discharge tube (4) is to prevent water leaking from reservoir into
toilet by fitting in rabbetted region at the interior surface of
discharge bearing (1) (shown in FIG. 2 and FIG. 4) when discharge
process is not performed. Segments (11) attached to upper and lower
sides of discharge gasket (12) are used to fix the place of
discharge gasket (12) on discharge tube (4).
[0073] Styrofoam (10) shown in FIG. 8 has a cylindrical structure
wherein discharge tube engagement opening (61) is located
throughout in the middle, and two longitudinal styrofoam channels
(62) extending as opposed, in which discharge tube styrofoam
corrugations (76) engage, are located at the interior surface of
said opening.
[0074] Discharge bearing support (8) shown in FIG. 9 has a body in
flat elongated plate form and discharge bearing support finger (81)
is located at its one end. This body has a discharge bearing
support lower region (83) formed in one-piece to the middle extent
hereof and subsequently and a discharge bearing support upper
region (85) formed in two arms which has a discharge bearing
support space (84) as a long gap in the middle hereof. Discharge
bearing support arm (82) located at the other end of discharge
bearing support (8) is conjoined with discharge bearing support
upper region (85). In mounting of stoppered discharge system (A),
discharge bearing support (8) is attached to discharge bearing
support channel (31) by discharge bearing support finger (81) and
to discharge bearing support finger engagement space (32). In
mounted state of stoppered discharge system (A), discharge bearing
support arm (82) is attached to a fixed point in the system or in
reservoir.
[0075] Pull arm (5) shown in FIG. 10 comprises a pull arm grip (94)
in a stick form, a pull arm eyelet (91) at one end of this grip in
a circular form and pull arm jaws (92) in a U-shaped form at the
other end hereof. Also, two pull arm fingers (93) facing as opposed
to each other are located at the ends of pull arm jaws (92) and at
the interior side of U-form and these fingers are attached into two
finger engagement recesses (71) at upper side of discharge tube
(4).
[0076] Styrofoam clip (9) shown in FIG. 11 is a part attached to
styrofoam clip abutment rabbet (73) on discharge tube (4) and is in
two nested rings form in which interior ring has an interrupted and
elastic structure.
[0077] Styrofoam lower plate (13) shown in FIG. 12 has a disk
shaped structure and styrofoam lower plate water passage openings
(51) are located hereon and in the middle hereof is located a
styrofoam lower plate opening (52) having two channels in which
styrofoam engagement surface (74) placed on discharge tube (4)
could be passed. Styrofoam lower plate (13) shown in FIG. 2 and
FIG. 4, in mounted state of stoppered discharge system (A), is
located on styrofoam lower plate sitting surface (30) over
discharge bearing (1) and on the portion of lantern lower rabbet
(45) facing the interior portion of lantern (3). The aim of use for
styrofoam lower plate (13) is to provide a sitting surface (1) for
styrofoam and to provide discharging of water inside the lantern
(3) in a controlled way through styrofoam lower plate water passage
openings (51) hereon. Amount of water which lifts styrofoam (10) in
the lantern (3) and controls discharge time is adjusted by
styrofoam plate water passage openings (51).
[0078] In stoppered discharge system shown in FIGS. 1-4, by means
of pull arm connection part (16), styrofoam (10) and discharge
gasket (12), located in the lantern (3) and fixed to discharge tube
(4), are also lifted when pull arm (5) and connected discharge tube
are lifted upward. During discharge, as soon as discharge gasket is
lifted up, water in the reservoir starts to discharge by passing
from water passage channel (35) into discharge channel (34).
Discharge tube (4), upon suspending in water, helps discharging of
water in the reservoir by means of styrofoam (10). During discharge
process, if the user does not intervene, water level drops inside
lantern (3) or reservoir and then water could not lift styrofoam
(10) therefore discharging process is ended after discharge channel
(34) is closed by discharge gasket (12) on the discharge tube (4).
However when the user pushes down the pull arm (5) and then
connected discharge tube (4) by means of pull arm connection part
(16), water flow could be stopped before water level drops upon
closing the discharge channel (34) by discharge gasket (12).
[0079] Preferred stoppered discharge system (A) above is not
intended to limit the protection scope of the invention. In view of
the described knowledge by the invention, all modifications on this
preferred stoppered discharge system (A) should be interpreted in
the protection scope of the invention.
