Definitions

  • the present invention relates to a flush, with water reserve adjustable, for example and in particular for toilet bowls.
  • the present flush comprises, in accordance with the invention, additional elements, which will be described now and which allow it to not deliver, at each actuation of the zipper, only a determined portion and finely adjustable for the total mass of water contained in this tank 8.
  • a rotary drum 1 coaxial with the tank 8 and extending substantially over the entire height of this tank.
  • this drum is actually composed of two concentric tubes, or ferrules, of which an internal tube 1A and an external tube 1B which are secured by an upper disc, or common cover, 18.
  • the outer tube 1B rests in a coaxial circular groove 19 of the bottom 15 of the tank 8, this groove serving as a lower guide in rotation for the drum 1.
  • the lower part of the tube 1B has large openings 20 (see also FIG. 7A), while the inner tube 1A, shorter than the outer tube 1B, does not completely reach bottom of tank 8.
  • the diameter of the outer tube 1B is only slightly higher than that of the inner tube 1A, so as not to penalize the internal space of the drum 1.
  • the drum 1 rotates, inter alia, with the cylindrical upper portion 2C of the pull rod 2.
  • valve 2A and therefore the whole of the pull tab 2 is blocked in rotation by means of three radial rods 21 (see also Figures 10A and 10D) which are each respectively embedded (see in particular FIG. 6) in a slot, median and vertical, respective receiver 30 of three tilting stop pieces 4.
  • the three stop pieces 4 are placed 120 degrees relative to each other. They can tilt backwards, with elastic return towards the front, in the vertical plane, but they are fixed in rotation in the horizontal plane. Their role and conformation will be explained below.
  • the inner tube 1A is pierced by a few helical-shaped slots 22 for guiding a piston 3 (FIG. 1), these slots 22 being (FIG. 8A) all approximately parallel to one another. the other, to the parallelism corrections (necessary to allow the close) (these are not noticeable on this kind of drawing) and inclined relative to the axis of this tube 1A.
  • This piston 3 and its role will be explained below.
  • the tube external 1B comprises, on its external surface, two identical groups 23, 24 of grooves 25 for guiding the drum 1 in rotation.
  • the float 5 comprises (FIGS. 1 and 13A) two other pins, external and radial, 28 and 29, for indexing this float in two vertical guide rails 13 provided on the inside of the tank 8 and consequently this float is fixed in rotation and mobile only in translation vertical, we can easily understand that the vertical movement of the float will have for effect, in fact only in its descent phase as will be explained below, to do the drum 1 simultaneously.
  • FIGS. 1, 2, 5, 6, 11A, 11B, 12A to 12C we will now deal with the three tilting stop pieces 4 and elements with which they cooperate, i.e. on the one hand the valve 2A and on the other hand the piston 3.
  • tilting parts 4 are fixed to the bottom 15 and are articulated on the latter around respective horizontal axes 31. They are each supported by a return spring 32 which tends to bring them forward, that is to say towards the axis 33 of the flush.
  • Their active part is their part, or slice, before 34, that is to say that looking towards the zipper 2.
  • valve 2A constitutes the lower part of the zipper 2, which will itself be described in detail below He receives, as mentioned above, the seal 12, and its upper part 40 (FIGS. 10A and 10D) forms a annular enlargement which includes the annular notch 60.
  • the piston 3 is a solid body (FIG. 11A and 11B) which is movable in vertical translation and sliding along the central tubular part 2B of the zipper 2 but which is immobilized in rotation by the fact that its central orifice 41, by which it slides along the tubular middle part of the pull tab 2, has two flats 42, 43 respectively conjugated with two corresponding flats 44 45 (Figure 10D) of tube 2B.
  • the piston 3 has, as indicated above, a part frustoconical 38 which allows it to open the three tilting stops 4.
  • Three recesses 46 (FIG. 11A) allow free passage of water without loss of substantial charge.
  • Three radial pins 47 are introduced into the slots inclined 22 of the tube 1A, so that the rotation, in one direction or the other, of the drum 1 causes the piston 3 to rise or fall.
  • the rod 2C is integral with a washer 51, which has, on a portion of its circumference, a series of grooves formed by axial grooves 52, at number of eleven grooves in the example described here. Their role will be explained below.
  • the upper part 2C and its partially grooved washer 51 pass through a washer 6 for adjusting the volume of water, which itself passes at through the cover 11 and which is fixed to the upper flange 18 of the drum 1 by two screws 54
  • This washer 6 cooperates with a central orifice of the cover 11 to constitute the upper bearing level of the drum 1.
  • a radial pin 55 (FIG. 1) is provided in the central orifice of the washer 6. It cooperates with the grooved washer 51, in the sense that, being unable enter one of the grooves 52 (FIGS. 10B and 1) only when it is aligned vertically with it, its position in the washer 6 is adjusted so that one can therefore only lift the pull tab 2 when the two internal fingers 26, 27 (FIG. 13A) for indexing the float 5 in the external tube 1B are found respectively opposite a descending indexing groove 25B (FIG. 9A) of the outer surface of this tube.
  • the adjustment washer 6 has graduations, here from 0 to 10, which cooperate with a reference 56 of the cover 11 to adjust the volume of water discharged by the flush, for example liter per liter or even quarter liter per quarter liter.
  • a button, or handle, for handling 7 covers the part upper of rod 2C.
  • a radial nipple screw 57 enters the semicircular groove 53 of the rod 2C, which blocks this gripping button 7 in translation relative to the pull tab 2.
  • this groove 53 allows the button 7 to rotate freely, in total only about half a turn, from this zipper 2.
  • the piston rises to a height which depends on the angle of rotation of the drum 1, and therefore of the graduation chosen on the adjustment washer 6.
  • the height position maximum possible of piston 3 this position corresponding to the graduation "10" of the washer 6 and therefore at a maximum rotation thereof.
  • valve 2A then comes to open ( Figure 2) until it comes to rest on its seat maintenance in the open position which is constituted by the three aforementioned notches 36 ( Figure 12C) of the three tilting parts 4 (that the return force of the springs 32 to be brought forward, against the valve 2A, as soon as the piston 3 is raised).
  • the water is then suddenly evacuated, through the drain orifice 16, towards the toilet bowl, or to any other user device.
  • This simultaneous rotation of the cylinder 1 also causes the descent simultaneous piston 3, which is indexed by its pins 47 in the helical slots 22 of the inner tube 1A of the drum 1.
  • the float 5, and therefore the water level only went down of a height corresponding to the descent of the piston 3, and therefore proportional to the initial angle (graduation "8") of rotation of button 7.
  • the volume of water discharged by the drain port 16 is therefore also limited to a portion of the total water level of the tank 8, this portion being determined by this angle of rotation.
  • this angle corresponds to the graduation "8" and if the graduation "10" corresponds to an ascent of the piston 3 for which all of the water in the tank is evacuated when the zipper 2 is then raised, we will only have evacuated eight tenths of the total volume of water in the tank.
  • the arm 9 of the float 5 drives closing the tap 10, which closes the water supply.
  • the toilet flush is then ready for a new use, with a volume of water to be drained which will be new chosen by the user, depending on the angle he will start with turn the operating knob 7 and therefore the selected scale on the washer adjustment 6.
  • the indexing drum 1 could, instead consist of two concentric tubes 1A and 1B each provided with a index fingerprint, consisting of only one ferrule provided with a first index fingerprint, for example formed by grooves or slides, on its internal face and a second indexing imprint, too formed for example by grooves or slides, on its outer face.
