Description

TITLE OF THE INVENTION: A CONTROL SYSTEM FOR A FLUSH TANK
MECHANISM FOR RELEASING A LARGE OR SMALL RINSING VOLUME AT
THE CHOICE OF THE USER
DESCRIPTION
The present invention relates to the field of toilet appliances with flush tanks and relates in particular to a control system for a flush tank mechanism for releasing a large or a small rinsing volume, at the choice of the user, for rinsing a toilet bowl.
In order to limit the wastage of water in toilet appliances such as toilets and, consequently, the quantities of water to be re-treated, there are various control systems allowing the user to release, at their choice, a small or a large volume of water for rinsing a toilet bowl. The following patent applications disclose such control systems: the U.S. patent application US6163897A, the
European patent application EP2072696A1, the German utility model application DE29510495U1, the French patent application FR3057285A1 and the European patent application
EP2824247A1. However, such existing control systems are not very robust, are complicated to manufacture and to assemble, and expensive because of the large number of parts which compose same.
The aim of the present invention is to overcome the drawbacks of the prior art by proposing a control system for a flush tank mechanism for releasing a large or a small rinsing volume, which, compared to the prior art, is more robust, simpler to produce and less expensive.
The object of the present invention is thus a control system for a flush tank mechanism, characterized in that it comprises: a hollow cylindrical casing, the upper end of which is open and the lower end of which has a bottom comprising a bore, said casing being configured to be mounted on a flush tank cover or wall-mounted flush control panel; a large volume control button having a pressing surface under which a control rod is attached being placed axially in the casing and goes through the bore of the casing bottom, the lower end of the control rod being configured to be connected to a flushing mechanism; a small volume control button having a pressing surface under which a circular plate is attached inside the casing by means of a vertical partition, said plate comprising a bore letting through the control rod of the large volume control button; a first compression spring placed between the bottom of the casing and the underside of the plate of the small volume control button; a second compression spring placed between the upper face of the plate of the small volume control button and the underside of the pressing surface of the large volume control button, the upper face of the pressing surface of the small volume control button being level with the upper opening of the casing when the system is at rest, a stop washer being placed at the lower end of the control rod of the large volume control button for limiting the upward course of the large volume control button so that the upper face of the pressing surface of the large volume control button is level with the upper opening of the casing when the system is at rest, at least one of the underside of the pressing surface of the large volume control button and the upper face of the plate including at least one protuberance configured for abutting against the other of the underside of the pressing surface of the large volume control button and the upper face of the plate when pressing the large volume control button, so as to prevent damage to the second spring; and at least one stop placed in the casing and configured to limit the course of the plate in the casing from the rest position thereof; such that, when a user simultaneously presses the small volume and large volume control buttons, the small volume and large volume control buttons simultaneously move down into the casing until the at least one stop stops the course of the plate, the lowering of the control rod then being limited to a first distance D1 for the release of a small rinsing volume; and when a user presses only the large volume control button, the large volume control button moves down into the casing until the at least one protuberance comes into abutment, then the plate, driven in this way by the large volume control button, moves down into the casing until at least one stop stops the course of the plate, the control rod then moves down by a distance Di which, by addition to the first distance D1, makes the release of a large rinsing volume possible. “Large volume control button” means a control button for releasing a large volume of rinsing water when a user presses the button. “Small volume control button” means a control button for releasing a small volume of rinsing water (i.e. a rinsing volume smaller than the large volume) when a user presses the button.
Thus, when the user simultaneously presses on the large volume and small volume control buttons, the latter move down into the casing over a first distance (i.e. until the underside of the plate is in contact with the upper edge of the at least one stop of the casing), so that when the lower end of the control rod is connected to a flushing mechanism, the movement of the control rod over the first distance leads to the release of a small volume of rinsing water into the toilet bowl.
Otherwise, when the user presses only the large volume control button, the latter moves down into the casing until the at least one protuberance placed on one of the underside of the pressing surface of the large volume control button and the upper face of the plate comes in contact with the other of the underside of the pressing surface of the large volume control button and the upper face of the plate, and then, when the user continues to press further, the large volume control button continues its course and drives the plate along until the plate is in contact with the at least one stop of the casing. The large volume control button thus moves down over a second distance {greater than the first distance) into the casing, so that when the lower end of the control rod is connected to a flushing mechanism, the movement of the control rod over the second distance leads to the release of a large volume of rinsing water into the toilet bowl.
The second compression spring is thereby compressed only when the user presses the large volume control button alone.
The stiffness of the first and second compression springs must be sufficient for raising the two control buttons to the rest position (i.e. level with the upper opening of the casing) when the user releases their pressing.
The control system according to the present invention can thus be installed on a flushing system comprising a flush tank on which is placed a flush tank cover or wall-mounted flush control panel comprising an opening, the flushing system further comprising a flushing mechanism placed in the flush tank, the casing of the control system being inserted into an opening on the tank cover or wall-mounted control panel, and the lower end of the control rod of the control system being connected to the flushing mechanism.
Preferentially, the plate is situated substantially at mid- height in the casing when the control system is at rest.
Preferentially, the upper edge of the at least one stop in the casing is located substantially at one third of the 5 depth of the casing.
Thus, contrary to the prior art, because of the limited number of parts which compose the control system, the control system according to the present invention is more robust, simpler to manufacture and less expensive.
According to a particular feature of the invention, the control rod has a shoulder positioned in contact with the underside of the plate when the system is at rest, so that, when a user only presses on the pressing surface of the small volume control button, the plate drives the control rod until the at least one stop stops the course of the plate, the lowering of the control rod then being limited to the first distance Dl.
Thereby, when the user only presses the small volume control button, the pressing drives the lowering of the large volume control button and the course is limited by the distance between the underside of the plate and the upper edge of the at least one stop (i.e. the first distance), then when the user releases pressing of the small volume control button, the first spring pushes the assembly back to the rest position. The presence of the shoulder on the control rod thus makes the release of the small rinsing volume possible when the user only presses the small volume control button.
The pressing of the underside of the plate on the shoulder of the control rod ensures that the pressing surfaces of the two control buttons are simultaneously level with the upper opening of the casing when the system is at rest.
According to a particular feature of the invention, the at least one stop placed in the casing for limiting the lowering of the plate is at least one of: a tube section provided on the bottom of the casing or on the underside of the plate; at least one protrusion provided on the bottom of the casing or on the underside of the plate; and at least one vertical rib on the inner lateral surface of the casing, the upper end of which serves as a stop for the plate.
Indifferently, the tube section or the at least one protrusion can be placed inside the first compression spring or outside the latter.
Indifferently, the tube section or the at least one protrusion can be rigidly attached to the bottom of the casing or to the underside of the plate.
In a variant, the tube section can be an independent part forming a bowl with a bottom for receiving the first compression spring.
The tube section, the at least one protrusion or the at least one vertical rib thus limits the course of the plate in the casing, so as to prevent damage to the first compression spring.
According to a particular feature of the invention, the at least one protuberance is a protrusion with the shape of a crown section.
The height of said protrusion is substantially greater than the height of the second compression spring in the compressed position so as to prevent a crushing of said second spring.
In a known manner and advantageously, the size of the pressing surface of the large volume control button is greater than the size of the small volume control button.
Thus, the user can easily differentiate between the two control buttons.
According to a particular feature of the invention, the pressing surface of the large volume control button has a 5 size substantially equal to three quarters of the upper opening of the casing, and the pressing surface of the small volume control button has a size substantially equal to one quarter of the upper opening of the casing.
According to a particular feature of the invention, the stop washer placed at the lower end of the control rod is fastened by means of a screw and a lock nut, the diameter of the stop washer being greater than that of the bore at the bottom of the casing, the stop washer being configured for abutting against the outer surface of the bottom of the casing in the rest position of the flushing control system.
The stop washer thus limits the rise of the large volume control button when the system is at rest.
The screw is screwed axially into the lower end of the control rod, and the lock nut is screwed onto the screw for locking the washer against the lower end of the control rod, the screw and the lock nut thus allowing the length of the system to be adapted to the configuration of the flushing system.
According to a particular feature of the invention, the outer lateral surface of the casing comprises a means of fastening, such as an external thread associated with a lock nut, for fastening the casing onto a flush tank cover or a wall-mounted flush control panel.
Thus, once the casing is installed in the opening of the tank cover or of the wall-mounted control panel, the lock nut can be screwed onto the external thread of the outer lateral surface of the casing for fastening the casing to the tank cover or the wall-mounted control panel.
According to a particular feature of the invention, the lower part of the control rod has a non-circular cross- section, such as peripheral grooves, and the bore in the bottom of the casing has a cross-section matching the cross-section of the lower part of the control rod so as to prevent the rotation of the control rod in the casing.
Thus, the non-circular cross-section of the lower part of the control rod fitted into the bore with matching shape in the bottom of the casing, makes it possible to prevent the rotation of the control rod when tightening the adjustment screw at the lower end of the control rod.
In order to better illustrate the subject matter of the present invention, a preferred embodiment will be described hereinafter, as a non-limiting illustration, with reference to the enclosed drawings.
On these drawings: [Fig. 1] is a cross-sectional view of a control system for a flushing mechanism according to the present invention, in the rest position thereof; [Fig. 2] is a cross-sectional view of the control system, in the small rinsing volume position thereof; [Fig. 3] is a cross-sectional view of the control system in the large rinsing volume position thereof; [Fig. 4] is an exploded view of the control system.
Referring to Figures 1 to 4, it can be seen that a control system for a flushing mechanism 1 according to the present invention, is represented therein.
The control system 1 comprises a hollow cylindrical casing 2 wherein are placed a large volume control button 3 and a small volume control button 4.
The hollow cylindrical casing 2 has an upper opening 2a surrounded by a flange collar 2b.
An external thread 2c is formed on the outer lateral surface of the casing 2, under the flange collar 2b. A lock nut 5 can be screwed onto the external thread 2c of the casing 2, so as to allow the casing 2 to be fastened onto a flush tank cover or to a wall-mounted panel for controlling the flushing (not shown in the figures).
In practice, the casing 2 is first inserted into an opening of the tank cover or of the wall-mounted control panel until the flange collar 2b abuts against the front face of the tank cover or of the wall-mounted control panel. The lock nut 5 is then screwed onto the external thread 2c of the casing 2 until the lock nut 5 comes into abutment against the rear face of the tank cover or of the wall- mounted control panel.
The lower end of the casing 2 has a bottom 2d comprising an axial bore 2e which extends into an external tube 2f.
The large volume control button 3 has a pressing surface 6 under which a control rod 7 is fastened, which is placed axially in the casing 2 and which crosses through the bore 2e of the bottom 2d of the casing 2 and opens out from the outer tube 2f.
It should be noted that the casing 2 could also not comprise an external tube 2f, the control rod 7 then opening out directly from the bottom 2d of the casing 2, without departing from the scope of the present invention.
The control rod 7 is hollow and has a tubular upper part 7a and a grooved lower part 7b. An internal thread is formed in each of the upper 7a and lower 7b parts of the control rod 7. A threaded rod 8 is rigidly attached to the underside of the pressing surface 6 of the large volume control button 3, and the upper part 7a of the control rod 7 1s screwed onto said threaded rod 8.
The bore 2e and the outer tube 2f of the casing 2 into which the lower grooved part 7b of the control rod 7 is inserted, have a cross-section matching the cross-section of the lower grooved part 7b of the control rod 7, so as to prevent the rotation of the control rod 7 in the casing 2.
The control rod 7 also has an external collar 7c provided between the upper 7a and lower 7b parts thereof, said external collar 7c forming a shoulder on the control rod 7.
A stop washer 9 is fastened onto the lower end of the control rod 7 by means of a screw 10 and of a lock nut 11, the diameter of the stop washer 9 being greater than the diameter of the outer tube 2f of the casing 2.
In practice, the lock nut 11 is first screwed onto the screw 10, then the stop washer 9 is inserted onto the screw 10. The screw 10 is then screwed into the lower part 7b of the control rod 7, and the lock nut 11 is then screwed onto the screw 10 so as to lock the stop washer 9 against the lower end of the control rod 7, the screw 10 and the lock nut 11 thus allowing the length of the system to be adapted to the configuration of the flushing system.
As shown in Figure 1, the stop washer 9 is configured for coming into abutment against the lower end of the outer tube 2f of the casing 2 in the rest position of the flush control system 1.
The stop washer 9 thus makes it possible to limit the upward course of the large volume control button 3 so that the upper face of the pressing surface 6 of the large volume control button 3 is level with the upper opening 2a of the casing 2 when the system 1 is at rest.
The head of the screw 10 is intended for being connected to a flushing mechanism (not shown in the figures).
The small volume control button 4 has a pressing surface 12 under which is fastened, by means of an arched vertical partition 13, a substantially circular plate 14 located inside the casing 2, said plate 14 comprising a bore 14a crossed through by the upper part 7a of the control rod 7 of the large volume control button 3.
A first compression spring 15 is placed between the bottom 2d of the casing 2 and the underside of the plate 14 of the small volume control button 4.
A second compression spring 16 is placed between the upper face of the plate 14 of the small volume control button 4 and the underside of the pressing surface 6 of the large volume control button 3.
In the rest position as shown in Figure 1, the underside of the plate 14 of the small volume control button 4 is in contact with the upper face of the external collar 7c of the control rod 7, in such a way that the pressing surfaces 6 and 12 of the large volume 3 and small volume 4 control buttons are level with the upper opening 2a of the casing 2.
The plate 14 is located substantially at mid-height in the casing 2 when the control system 1 is at rest.
The upper face of the plate 14 of the small volume control button 4 comprises three protuberances 17 such as protrusions which have the same height and are configured for coming into abutment against the underside of the pressing surface 6 of the large volume control button 3 when the large volume control button 3 is pressed, so as to prevent damage to the second compression spring 16.
It should be noted that the upper face of the plate 14 could also include any number of protuberances 17, without departing from the scope of the present invention. As an example, only one protuberance 17 with the shape of a crown section could also be used, without departing from the scope of the present invention.
In a variant, the underside of the pressing surface 6 of the large volume control button 3 could also include one or more protuberances configured to come into abutment against the upper face of the plate 14 when the large volume control button 3 is pressed, without departing from the scope of the present invention.
At least one vertical rib (as an example, two in Figures 1 to 3) extending from the bottom 2d of the casing 2, is formed on the inner lateral surface of the casing 2, so that the upper end thereof forms a stop 18 for limiting the course of the plate 14 in the casing 2 from the rest position thereof, which makes it possible to prevent damage to the first compression spring 15.
The upper end of the at least one vertical rib is located substantially at one third of the depth of the casing 2.
It should be noted that the stop(s) 18 for limiting the course of the plate 14 in the casing 2, could also be made by means of a tube section provided on the bottom 2d of the casing 2 or by at least one protrusion provided on the underside of the plate 14, without departing from the scope of the present invention.
The bearing of the underside of the plate 14 on the upper face of the external collar 7c of the control rod 7 ensures that the pressing surfaces 6 and 12 of the two control buttons 3 and 4 are simultaneously level with the upper opening Za of the casing 2 when the system 1 is at rest.
The pressing surfaces 6 and 12 of the large volume 3 and the small volume 4 control buttons match each other and together obstruct the entire circular upper opening Za of the casing 2 in the rest position of the system 1 (as shown in Figure 1), the size of the pressing surface 6 of the large volume control button 3 being greater than the size 12 of the small volume control button 4.
Preferentially, the upper face of the assembly consisting of the two pressing surfaces 6 and 12 has a slightly domed shape.
As an example and in a known manner, the pressing surface 6 of the large volume control button 3 has a size substantially equal to three quarters of the upper opening 2a of the casing 2, and the pressing surface 12 of the small volume control button 4 has a size substantially equal to one quarter of the upper opening Za of the casing 2.
As shown in Figure 2, when a user presses only on the pressing surface 12 of the small volume control button 4 or simultaneously on the pressing surfaces 6 and 12 of the small volume 4 and the large volume 3 control buttons, the plate 14 (abutting against the external collar 7c of the control rod 7) drives the control rod 7 in such a way that the small volume 4 and the large volume 3 control buttons simultaneously move down into the casing 2 until the underside of the plate 14 comes into contact with the stop 18 (i.e. the upper end of the at least one vertical rib} of the casing 2, the lowering of the control rod 7 then being limited to a first distance D1 which corresponds to the distance between the underside of the plate 14 and the upper end of the at least one vertical rib when the system 1 is at rest.
When the screw 10 screwed into the lower part 7b of the control rod 7 is connected to a flushing mechanism, the lowering of the screw 10 over the first distance D1 leads to the release, by means of the flushing system, of a small volume of rinsing water into the toilet bowl of the sanitary appliance. Then, when the user releases the pressing, the first compression spring 15 pushes the assembly back into the rest position (as shown in Figure 1).
As shown in Figure 3, when the user presses only on the pressing surface 6 of the large volume control button 3, the large volume control button 3 moves down into the casing 2 until the underside of the pressing surface 6 thereof comes into abutment against the protuberances 17 provided on the upper face of the plate 14, the control rod 7 thus moving down over an intermediate distance Di which corresponds to the distance between the underside of the pressing surface 6 of the large-volume control button 3 and the upper ends of the protuberances 17 when the system 1 is at rest.
Then, when the user continues to press further the large volume control button 3, the plate 14 is driven by the pressing surface 6 of the large volume control button 3 and moves down into the casing 2 until same comes into contact with the stop 18 (i.e. the upper end of the at least one vertical rib) of the casing 2, the control rod 7 then moving down over a second distance D2=Di+D1.
When the screw 10 screwed into the lower part 7b of the control rod 7 is connected to a flushing mechanism, the lowering of the screw 10 over the second distance D2 (greater than the first distance D1) leads to the release, by means of the flushing system, of a large volume of rinsing water into the toilet bowl of the sanitary appliance. Then, when the user releases their pressing, the stiffnesses of the first and second compression springs 15 and 16 are sufficient for raising the two control buttons 3 and 4 to the rest position (i.e. level with the upper opening 2a of the casing 2).
It is understood that the particular embodiment which was just described was given as an indication, and is not limiting, and that modifications can be made thereto without departing from the present invention.
