To facilitate access to the catcher 30 to its fitting with a toilet tablet, the invention proposes to provide between the cistern and the actuator plate 2 an intermediate frame 8, and form between the intermediate frame 8 and the actuator plate 2 movable connecting means, via which the actuator plate from an installation position closing the wall opening 4 into an opening position which opens the wall opening 4 for equipping the collecting basket (30) can be transferred.

Description

The invention generally relates to an arrangement for introducing a water treatment agent into a flushing water tank for a toilet.

In particular, the invention relates to a toilet actuation unit with an actuation plate which can be placed in front of a wall opening behind a WC, comprising at least one flush button for triggering a flush, at least one transmission element for transmitting a force exerted on the flush button to a flush valve arranged in a cistern. Further, in the cistern a partially perforated catcher or chute for receiving a water treatment agent is provided which emits its active ingredients to the surrounding rinse water. Such water treatment agents are usually acidic cleaners for toilets which serve to remove urine scale and limescale deposits and other contaminants.

The actuator plate comprises one or more actuating units, preferably buttons for triggering a flushing operation, according to the newer state of the art, preferably for a large and a small flushing volume. The wall opening or the actuating plate used in this defines a mounting plane with a coordinate system, which is defined in accordance with this invention with (x, y) coordinates. The z-axis of this coordinate system is perpendicular to this mounting plane.

Such a device is for example from the EP2226438 known. The device disclosed in this document comprises an attached at the bottom of a hinge on the wall and hinged forward folding actuator plate for a toilet, so that by opening a wall opening is released, in which designed as a toilet tab water treatment agent in a chute in the Rinsing water tank can be inserted. In the solution according to EP2226438 the access is completely covered by the flush plate. It is therefore not visible. The opening is only possible with a pivoting movement. This has the disadvantage that flush mounted flush plates in the wall do not work with this solution. Especially for small, very flat constructive actuator plates, the space for a deratig complicated mechanism is not available.

The in the DE22904649 disclosed solution not generic includes a suspended in a cistern float chamber into which a designed as a cleaning liquid water treatment agent can be filled and which emits in each regular operation of the toilet also this water treatment agent in the rinse water. In the device according to the DE29904649 it requires a flap, a lid or a plug as access to the cistern. However, this contradicts today's design requirements for a modern bathroom. On the one hand, access should be easy and, on the other hand, not visible.

Both solutions are associated with the disadvantage that access to the cistern is relatively complicated and yet only limited possible. Furthermore, both solutions are relatively maintenance-prone.

Based on this prior art, the invention is based on the object to avoid these disadvantages, at least partially, and to provide a toilet operating unit, which is stable and simple and also allows improved access to the chute.

According to the invention this object is achieved in a toilet actuator unit of the type mentioned by the features of the main claim. Advantageous further developments are laid down in the dependent claims.

In the simplest embodiment, the object is already achieved in that it comprises a arranged between the cistern and the actuator plate intermediate holder to which the actuating plate is releasably fixable by means of fixing means. These fixing means are designed according to the invention to transfer the actuating plate from a closure closing the wall opening into an opening position releasing the wall opening for equipping the collecting basket. Thus, in the open position so the entire wall opening is open, whereby access and usability over the prior art are significantly improved. To open the actuator plate must be removed only to the front and swung down, which can be done without tools.

Preferably, these fixing means are designed to allow the transfer from the closed to the open position by means of a simple pulling / rotating movement, particularly preferably without tools. In the particularly preferred embodiment, the fixing means comprise a between actuating and intermediate holder arranged in the z-direction to the mounting plane extending rotary push rod, around which the actuating plate is rotatable and a fixing element for fixing the actuating plate in the closed position.

The intermediate holder is sufficiently stable for holding the operating plate in the movement from the closed to the open position and vice versa. Preferably, the intermediate holder is inherently rigid, so by the forces occurring or the weight of the actuator plate is not twisted or bendable, which is achieved either by a suitable choice of material, eg. B. by training of metal, by the geometric design, preferably in the form of a closed profile frame or intermediate frame, more preferably in the form of a closed angle profile, or by a combination of the choice of material and the geometric design.

The intermediate holder may be fastened via fastening means in the surrounding wall opening, z. B. by means of screws or clamps. However, the attachment is particularly preferably carried out because of the easier accessibility via spacer elements on a splash guard of Spülwasserkastens, so a closure plate for closing an opening of the cistern. The function of the splash guard is to complete the cistern to the outside, so to prevent the squirting of water during filling. The detachable attachment of the splash guard on Spülwasserkasten is usually done by screw caps.

In the coordinate system of the invention, the intermediate holder and the splash guard thus extend in the z-direction parallel to the rear offset to the x, y coordinates of the mounting plane.

The fixing means between the installation position in the front operating plate and the intermediate holder arranged between the splash guard and this actuator plate preferably comprise a longer trained push / turn bar and a slightly shorter fixation rod, these two rods preferably attached at opposite ends to the back of the actuator plate and are releasably insertable in the intermediate frame.

The attachment of the intermediate frame on the splash guard is preferably carried out by means of fastening screws, particularly preferably by means of so-called corrugated screws, ie long screws, which are preferably made of plastic. These corrugated screws pull the intermediate holder into the installation position or against the wall. This attachment is advantageous over the alternative attachment of the intermediate frame to the wall by means of clips or screws, because replacement and maintenance are relatively easy. The corrugated screws are also standard components, so that you can rely on standard components of the toilet technology.

The holes in the existing / existing splash guard can be used so that you can continue to use standard components. As a rule, however, the actuating unit proposed by the invention or a kit comprising it will comprise a splash guard, the intermediate holder and an actuating plate. At least the splash guard should have a first pivot hole for receiving the rotary / push rod and another fixing hole for inserting the fixing element or the Fixierstange.

It is understood by those skilled in the art that the term 'wall' is not necessarily to be understood as a masonry wall. Rather, this term includes z. As well as a formed of connected profile frame pretext with a front planking of plasterboard on which tiles can be glued.

On the basis of the aforementioned disadvantages of the prior art and the resulting task, the invention also relates to a retrofit kit comprising a previously described actuation unit.

Further details, advantages and features of the invention can be taken from the following part of the description, in which an embodiment of the device according to the invention is explained in more detail with reference to 7 drawings. Show it:

1 a schematic side view of the toilet actuator unit installed in a wall in front of a concealed cistern;

2 a side view of the toilet operating unit without wall and concealed cistern;

3 a front perspective view of the toilet operating unit;

4 a rear view of the toilet operating unit;

5 a side perspective view of the toilet actuator with attached actuator plate;

6 a front view of the toilet actuator unit installed in a cistern and turned off actuator plate; and

7 an exploded view of the toilet actuator with its components.

Identical or equivalent parts are provided with the same reference numerals.

According to 1 the toilet operating unit essentially consists of a front side operating plate 2 , one in installation position behind the actuator plate 2 in a wall opening 4 a wall 6 or pretext arranged intermediate frame 8th , which has two horizontally spaced fixation rods 10 on a splash guard 12 is attached, with an access opening in the front of a concealed cistern 14 is closable. The wall opening 4 in the present case has the dimension of about 30 × 15 cm and is about 50 cm above the top of a wall 6 provided on the back toilet WC.

In the presentation according to 2 are the actuator plate 2 and the intermediate frame 8th better recognizable. The actuator plate 2 consists of a frame-like profile of substantially rectangular shape for insertion into a standard opening above a toilet and comprises a peripheral support flange, which in the installed position front to the edge of the opening 4 in the wall 6 rests.

The actuator plate 2 Also includes two circular receptacles of different sizes for relatively movable recording of operation buttons to trigger various flushing operations with large and small flushing. The front of the actuator plate 2 is further characterized by a in 1 shown schematically and arbitrarily designable cover plate closed, which by the in 5 protrude through the buttons shown for the operation of the cistern.

The actuator plate 2 comprises on its back, so in the z-direction extending a push / turn bar 16 with a length of about 20 cm, which in. Installation position is rotatable and longitudinally displaceable in one of the intermediate frame 8th provided insertion opening 18 at the lower end of a piece on a first short leg of the intermediate frame 8th molded and extending parallel to the mounting plane side plate 19 , In the longitudinal direction of the actuator plate 2 from the push / turn bar 16 spaced this includes a likewise projecting in the z direction fixing pin 20 which in the installed position in a fixing opening 22 in a corner plate 21 on the left side upper end of the intermediate frame 8th intervenes. By the distance from the push / turn bar 16 and the fixing pin 20 a rotational movement in the inserted position is effectively prevented. To open the actuator plate, however, only pulled off to the front and swung down, which can be done without tools.

The splash guard 12 is formed as a closure plate, with which an opening in the front of the concealed cistern 14 can be closed and which rests in the installed position with the peripheral flange on the front of this opening and by means of two spaced apart longitudinally and at the lower end of the splash guard 12 rotatably inserted fixing screws 24 . 26 in the target position is releasably fixed to the concealed cistern 14 ,

The splash guard 12 points below the fixing hole 22 a hinged at the bottom pivotally mounted on the splash guard flap 28 on which in the 2 in the open position and in the 3 is shown in the closed position, and over which an access opening for a catcher 30 to accommodate a toilet tablet is releasable, at the back of the splash guard 12 also pivotally mounted or suspended.

The 5 shows by pulling forward and turning down 90 degrees around the push / turn bar 16 from the closing pivoted to the open position actuator plate 2 , In this position is the flap 28 accessible, leaving a toilet tablet in the catcher 30 is einwerfbar.

The formed in the present case as a metal frame intermediate frame 8th is adapted to the size of the respective wall opening and has two mutually parallel, the longitudinal sides defining longitudinal leg, which are also connected to each other extending parallel, the short sides defining transverse leg to form a closed rectangular profile throughout, to form a closed profile frame. To achieve the necessary inherent rigidity is the intermediate frame 8th formed from a circumferentially closed L-profile having a central passage opening for the passage of the transfer elements of the key movement on the rinse.

The intermediate frame 8th is over two corrugated screws extending in the z-direction 32 . 34 , which consist of a cylindrical central rod, along the longitudinal direction of which equidistantly spaced-apart annular, radially projecting discs are integrally formed on the splash guard 12 attached, which predefined threaded opening for insertion or screwing this corrugated screws 32 . 34 having. Thus, by screwing in the corrugated screws 32 . 34 the intermediate frame 8th as required and precisely in its nominal position in the relationship between the splash guard 12 and the cover plate 2 adjustable by inserting the corrugated screws into the splash guard and fixing them with a 90 ° turn. In this case, different plaster or tile thicknesses can be compensated. The intermediate frame is then bolted to the corrugated screws with screws. It can also a transverse offset to the mounting plane can be compensated.

The figure shows the cross section through an excuse behind a toilet ceramics, not shown, which is fixed below the passage opening to a flushing pipe of a built-in wall Spülwasserkastens.

Within the cistern a non-illustrated flush valve is arranged, which is actuated via a pivot lever assembly. To actuate this pivoting lever arrangement in the course of a rinsing operation, an actuating button depressibly provided in the actuating plate is pressed down and thus the actuating force is transmitted via the pivot lever construction to the flushing valve, preferably by raising the flushing valve.

The front of the cistern has an access opening through which the cistern for maintenance is accessible and which is a splash guard, so a plate-like cover, which is screwed or snapped, concealable.

At the outer edge of the passage opening of the intermediate frame according to the invention is placed, which surrounds the passage opening like a frame and is presently designed as a cross-section Z-profile, so as a profile frame, a front auflegbaren on the front wall front flange, extending from this front flange to the rear horizontal flange and again has parallel to the front flange upwardly extending rear flange, wherein on the inside of the through hole is defined within the profile frame.

This profile frame is therefore placed in the present embodiment on the front edge of the wall directly behind the actuator plate. The actuator plate in turn has on its rear side in the installed position two horizontally in the installed position spaced rods, which Zug- / or. Can absorb rotational forces. One of these two horizontally aligned rods is designed as a pull / rotary rod, so that the actuator plate can be easily pulled off to the front and then turned around or turned away around this pull / turn bar up or down, for access to the chute. When weggedrehter actuator plate so the water treatment agent, preferably a kind of sink or the like, are thrown through the passage opening in the profile frame after removal of the splash guard in the preferably rotatably hinged to the splash guard chute. Then, the actuator plate is pivoted back to the rest position or installation position back to the rotary / push rod.
