Abstract

A flushing system for a WC (toilet) cistern has two shafts (10,11) which are depressed by two tabs, one for partial flush and one for full flush. The shafts press onto tilt levers which operate the flushing system in conjunction with two floats. The shafts are coupled to the tilt levers by pivot action cams which effectively couple the two systems together when the full flush tab is pressed, and which leave the main flush mechanism open when the partial flush tab is pressed.

Description

Technical field

The invention relates to a flushing set for flushing cisterns with a float valve that can be used for both partial and full flushing, and further relates to a float cover with a main float and a valve body with a second float which is connected to the valve body and locking a device that locks the main float during the partial flush and a movable device with a first button to start the partial flush and a second button to start the full flush, as well as a first movable part effectively coupled to the first button which lifts the valve body to start the partial flush a second movable part connected by a button, the two movable parts having a pivotally mounted lever over the valve body.

BACKGROUND OF THE INVENTION

In the prior art, a flushing set of this type has become known from FR-A-2 676 480. It can be used for both partial and full flushing. For this purpose, the control device has two buttons which act together with the pivotally mounted lever. Partial flushing occurs with the first lever. The valve body is lifted. The main float in the float is locked in the float by a closing lever. In case of partial flushing the main float is not active. A second float is disposed on the valve body at approximately mid-height, which, after partial flushing, keeps the valve body in the raised position until the flushing water level drops below the second float. If the second float is above the flushing water level, the valve body no longer has a displacement and this is returned to the valve seat. In full flushing, the main float is unlocked via the connecting rod and the valve body is lifted at the same time. The main float, which is stored in the lower part of the flush tank, now works together

-2 with a second float onto the valve body and lifts it substantially until the flush tank is completely emptied. If the valve body returns to the valve seat, the main float will automatically lock again.

EP-A-0 723 050 discloses a dispensing set which is of similar design to the above-mentioned dispensing set. Here again, a locking lever is provided on the float cover, which locks the main float during partial flushing. When triggering a full flush, this lever is swiveled into an inoperative position while simultaneously lifting the valve body. During full flushing, the main float is active and a second float is also located on the valve body. However, only a second float is active in the partial flush.

DE-U-84 36 155 shows a flushing set in which either full or partial flushing can be selected. This flushing set is also provided with two floats. In the neutral position, both floats are locked by a clip. One of these floats is connected to the valve body. The float is locked in such a way that the valve body is lifted from the valve seat and thus the partial flushing is triggered. To actuate a full flush, the two shutters are lifted simultaneously with the sliding rod, with both floats acting on and lifting the valve tube. When starting a partial flush, the corresponding movable part does not lift the valve tube, as in the case of another flushing set, but only one closure is lifted. In order to raise the valve tube during partial flushing, a very large float must be used.

The flushing set described by the Applicant in DE-C-34 22 315 has become known. In this set, the movable device has a lever which rotates one of the trigger parts located above it and thus starts flushing, to interrupt flushing again rotating in the opposite direction. With this flushing set, both flushing and single button operation can be interrupted. However, this flushing set is not expected to be operated with two buttons.

EP-A-0 801 179 discloses a flushing set which is provided with two buttons and it is possible to select either partial or full flushing. To lock the main float, a lever is located on the float cover which releases the latch when the full flush is triggered, thus releasing the main float for discharge. The movement of this locking part takes place via the bridge and the pivot lever.

-3 For flushing kits, a compact arrangement is essential as far as automated assembly and cost-effective storage possible. Known flushing sets generally have many different individual components, resulting in costly assembly and expensive storage.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to provide a flushing set of the aforementioned type, characterized by a simple construction, allowing cost-effective storage of parts of small dimensions.

The task is solved according to the type of flushing set so that both levers are rotatable by means of the trigger and the trigger of the second movable part, when in the neutral position, blocks its lever to lock the main float. In the invented flushing set, the blocking does not occur on the float cover by the locking lever, but in the second movable part by means of a trigger. This trigger is also provided with a corresponding lever for the first movable part to allow rotation. Both moving parts thus have one trigger as well as one lever. Both levers are rotatably mounted and are operated by a vertically movable trigger. The two moving parts are the same and have the same bearing parts, which allows a very compact construction. Both triggers allow two-button operation, which is especially necessary for ceramic cisterns. It is essential in any case that the installation of the main float closing lever on the valve cover is omitted. The essential parts and parts are arranged above the valve body.

A particularly compact embodiment arises when, according to a further embodiment of the invention, the two movable parts are housed in a common housing. According to a further embodiment of the invention, the common cover is predominantly mounted on a support rod which is connected to the float cover at its lower end. The movable device then forms a unit with the float valve, which allows easy installation.

As already mentioned, the locking is effected by the first movable part, according to a further embodiment of the invention, only one clip is required to lock the main float, which in its simplest form constitutes a vertical rod which, at its lower end, abuts the main float.

A simple and reliable locking of the main float can be achieved in particular if, according to another embodiment of the invention, the lowering part has a head which is in a neutral position to the vertical inclined to the lever. When this trigger is depressed, the head is transverse to the stop of the power arm of the lever and rotated so that the main float is released and the valve body is lifted.

Further advantageous findings are apparent from the dependent claims, the following description and the figures. The exemplary embodiment of the invention is explained in more detail below with reference to the figures.

DETAILED DESCRIPTION OF THE INVENTION

The flushing set 1 shown in FIG. 1, consists essentially of one control device 2 and one float valve 23. The flushing assembly is mounted on the bottom of the flushing tank, not shown here, where the lower cylindrical discharge port 26 extends into an opening in the bottom of the flushing tank. The float cover 24 accommodates a valve tube 28 having at its lower end a rubber, elastic valve plate 31 which, in the position shown, closes the discharge opening, which is not visible here. For flushing, the valve body 28 is lifted and flushing water can flow through the orifice 25 of the float valve 23 into a toilet bowl (not shown). The upper opening 30 of the valve body 28 serves here as an overflow pipe.

In the float cover 24, which is open above, there is a float 27 which serves as the first and main float. Against the water displacement, the vertically positioned drawbar remains in the position shown in FIG. 1. This rod 22 is formed by a clip which, at its lower end 22b, is loosely laid on the top of the float 27. At the upper end 22a there is a rod

-522 loosely coupled by joint 12 to the double-arm lever 8 of the second movable portion 4. The position of the lever 8 shown in FIG. 1 is locked by the second trigger 6. Thus, the lever 8 cannot be rotated by the displacement of the main float 27. The locking of the lever 8 will be explained in more detail below.

The second float 29 is located on the valve tube 28 above the main float 27. The second float 29, the height of which can be adjusted, has a displacement force sufficient to allow the valve body 28 to float in a full flush tank. The float 29 may be of a plastics material whose specific gravity is less than 1, or may be an open sludge shock at the bottom. Because the float height is adjustable, different amounts of water can be used for partial flushing.

The control device 2 has two movable parts 3 and 4, which are located in a common housing and have a vertical pull rod 10 or 10, respectively. H that exceed the cover. These rods 10 and 11 are connected by a pushbutton 37, respectively. 38 as shown in FIG. 2. The cover in which the two buttons are located can be fitted from the top into the opening 41 of the flush tank cover. The ends of the rods 10 and 11 are rigidly connected by a bridge 39 to the buttons 37 and 37 respectively. 38. During assembly, the upper ends of the draw rods 10 and 11 may be introduced into flushing tanks of different heights. Arrows 42 indicate the direction in which the flushing buttons 37 and 38 move. One embodiment also applies to a trigger that is not performed manually, but automatically, or in some other way. When the button 37 is pressed, the first movable part 3 is actuated and a partial flushing is initiated. In FIG. The button 38 shown in FIG. 2 is used for full flushing. The partial flushing will be explained first and then complete.

In the case of a partial flush, the button 37 moves in the direction of the arrow 42, that is to say downwards. This movement is transmitted to the rod 10, which together with the body 40 compresses the spring 16, which is located in the housing 9. The lower end of the body 40 surrounds the hinge 14 and has a rotatable downwardly directed head 17. The body 40 forms the first with head 17 The head 40 also moves downwardly with the body 40 until it strikes the inclined surface 7b of the lever 7, while turning the lever 7 in the direction of the arrow 42 about the pivot axis 19. The impact point of the head 17 on the lever 7 is located according to FIG. Thus, when the button 37 is depressed, the head 17 touches the lever arm 7. In the said rotation of the lever 7, the rod 21 is lifted and is freely connected to the lever 7 by the joint 12. The lower end 21b of the rod 21 is connected to the bridge 32 When the rod 21 is raised, the valve body 28 is appropriately raised. Thus, the float valve 23 is opened and water can flow out of the flushing tank. In order to

When the water flows out, the valve body 28 does not immediately return to the closing position, it floats by means of the second float 29. As soon as the flushing water level reaches the bottom of the float 29, the discharge is balanced. And since there is no displacement, the valve body 28 snaps back into the closing position, as shown in FIG. 1. Such partial flushing shall consume three liters of water. The flush tank is refilled with an inlet valve (not shown) and contains about nine liters of water.

When the button 37 is no longer held after the partial flush has been triggered, the spring 16 returns the first trigger 5 to the position shown in FIG. 5. If partial flushing is to be interrupted, the button 37 must be pressed once more and the head 17 moves to the next surface 7b of the lever 7, the rod 21 thus moving against the displacement of the side float 29 to the closing position as shown in FIG. . 1. In the closed position, the water pressure on the valve plate 31 maintains the closed float valve 29 in the closed position. During partial flushing, a certain consumption of flushing water, e.g. three liters. During the partial flushing, the main float 27 remains in the position shown in FIG. 1 and, as already mentioned, is not in operation.

In full flushing, the push-button 38 moves downwards and this movement is transmitted to the drawbar 11 As in the case of a partial flushing, the guide body 40 moves downwards against the spring backward force 16. The guide body 40 forms a second trigger 6 with the head 18 This head 18 is also rotatably connected to the guide body 40 by a bridge 15. In the neutral position, the head 18 of FIG. 6 and 7 vertically inclined and contacts with its apex 18a the inclined surface 8a of the righting lever arm 8. The inclination of the position of the head 18 is determined by the corresponding inclination of the two upper abutment surfaces 18b. In the neutral position, the abutment surface 18b abuts the cover 9 under the pressure of the spring 16 on the cover 9. As already mentioned, the trigger 6 moves downward and the head 18 slides in the direction of the arrow 43 onto the surface 8a, on the lever arm 8 opposite the stop 8b ( Fig. 6). By further movement of the trigger 6, the lever 8 is rotated in the direction of the arrow 44 about the hinge 19 and thus lifts the rod 22. The lower end 22b of the rod 22 thus lifts from the main float 27 and moves its displacement against the arm 34 of the valve body 28. a carrier 13, which is arranged horizontally at the bottom and which according to FIG. 5 abuts the underside of the lever 7. The carrier 13 is firmly connected to the lever. In full flushing, the lever 8 is rotated, at the same time the lever 7 and also the rod 21 of the valve body 28 are lifted, and thus a full flushing occurs. The raised valve body 28 is lifted not only by the second float 29, but also by the main float 27. If the

- the float 29 above the flushing water level, the valve body 28 continues to float by the float 27 until the flushing tank is emptied. By pressing the button 37 again, flushing at full flushing can be interrupted at any time, as previously explained. After each flushing, the head 18 returns to the position shown in FIG. 6. To assume and maintain the inclined position of the head 18, it has a corresponding transverse stop surface 45 on its rear side. The head 18 moves back to the position shown in FIG. 1. In this position, as already mentioned, it locks the lever 8 against the displacement of the main float 27. The pivoting movement in the opposite direction is limited by the arm 46 of the drawbar 20.

The control device 2 is mounted on the upper end 20a of the draw bar 20. The cover 9 has a stop 9a at its lower end. which extends between the two ribs 20b. The movable device 2 is thus fixed loosely at the upper end 20a of the drawbar 20. During assembly, the drawbar 20 can be introduced with its upper end 20a on different flushing tanks. The corresponding buttons 37 and 38 of the control device 2 can thus be precisely positioned. Thus, it can be achieved that the buttons 37 and 38 can be precisely connected to the housing 36 with their upper side. Such assembly is necessary, in particular, for ceramic flushing tanks which, as is known, have relatively large tolerances.

Since both movable parts 3 and 4 are housed in one housing 9, a very compact and slim design can be used. The space required for the actuating device 2 is comparatively smaller than is substantially necessary, and thus the accessibility to the lower inner part of the tank is considerably improved when the cisterns are mounted. The individual parts of the movable device 3 can also be used in a flushing set which has only a button and which allows intermittent flushing.
