First, it presents a deck 1 as a platform assigned to the discharge tank control opening recessed The cover 1 is made in the form of a frame, so which can also be called the base framework. It is formed by a section 1.1 in the form of a flange, in which a piece is molded 1.2 collar protruding on the back side. In necklace 1.2 they are molded in one piece transverse souls 1.3 that extend on the inner side in the vertical direction as well as a central soul 1.4. The transverse souls 1.3 are provided with fasteners 1.5 in the form of perforations (holes) to pass fastening screws or clip elements (no represented). Through its fasteners 1.5, the cover 1 can be fixed directly on a recessed unit.

The transverse souls 1.3 are provided, in addition, recesses (perforations) 1.6, 1.7 for accommodation of centering elements 2.6 or for interlocking tabs of interlocking 2.7 of a second deck 2. The second deck 2 it presents a section 2.2 made in the form of a bucket, in which it is molded again a section 2.1 in the form of a flange. Section 2.1 in flange shape carries the locking tabs 2.7 that can interlock in the recesses 1.7 of the first deck 1, as well as centering elements 2.6 in the form of bolts, which are inserted into the 1.6 cylindrical recesses of the cover 1. The second cover 2 is inserted from the front side into the base frame, it is that is, the first cover 1. The transverse souls 1.3 with the 1.6 cylindrical recesses of the first cover are arranged back to the front side of section 1.1 in the form of a flange in such a measure that in the mounted state the second cover 2 finish flush with the front side of section 1.1 in the form of a flange of the first cover (see figures 2 and 3).

The central core 1.4 has two openings 1.8, in which supports are interlocked (not shown), in which drive pins or similar that release a reduced wash volume or a volume of full wash. Openings 1.8 match openings 2.8 made in section 2.2 in the form of a cuvette of the second cover 2 (see figures 15 and 18).

In section 2.2 in the form of a bucket, which protrudes on the back side with respect to section 2.1 in the form of flange, four sleeves protrude on the rear side 2.3 cylindrical, which are closed at the end and have along an axial rear zone an inner diameter and a diameter reduced outside. In the sleeves 2.3 are inserted 2.11 sliding bushes, which with its rear front side seat against the inner step 2.31 of the sleeve 2.3 correspondent. In the sliding bushes 2.11 are inserted sliding rods 3.3, which are attached to control elements 3.1, 3.2 in the form of buttons.

The front ends of the rods of Sliding 3.3 are fastened in 3.4 bushes, which are provided with 3.5 supports molded into them in one piece. The 3.5 brackets are made in the form of boxes or boxes and they have two perforations 3.6 on their front side, respectively, for accommodation with positive adjustment of 3.61 interlocking elements molded on the back side of the control elements 3.1, 3.2. Between the two perforations 3.6 a hole 3.7 is provided for housing a screw of countersunk head 3.8, which is screwed into a threaded hole in the front end of the sliding rod 3.3 assigned. In addition, a spike is molded into the support 3.5 in the form of a box 3.9 in the form of a tongue, which meshes with positive adjustment behind a stop made on deck 2.

Cover 2 has perforations for it. 2.9 in the form of slots assigned to spikes 3.9, through the which spikes 3.9 with play and are linearly scrollable, serving the outer edge of the corresponding 2.9 hole as a stop for the bent end towards the outside of the spike 3.9 assigned. The perforations 2.9 in the form of slots are arranged in the zone of two opposite steps 2.10 of section 2.2 made in the form of a bucket on deck 2 (see figures 2, 7 and 16).

Thanks to the sleeves 2.3, the bushings sliding 2.11 and sliding rods 3.3, the control elements 3.1 and 3.2, with which a wash is released complete or a reduced wash, are guided linearly in the Cover 1, 2 of two parts. In addition, the control elements. 3.1, 3.2 are elastically prestressed in the direction of their position normal (starting position), respectively, by springs 3.31 helicals that rest on deck 2.

In figures 15 and 16 it can be seen that sleeves 2.3 molded in one piece in section 2.2 in the form of cuvette of the second deck 2 look a little at section 2.2 in cuvette shape, serving the projection 2.32 as well as existing centering element or as radial support for the spring 3.31 helical in question. On the opposite side, the bushings 3.4 carrying the sliding rods 3.3 of the supports 3.5 detachably connected to the control elements 3.1, 3.2 se peek inside the coil springs 3.31.

In addition, in the 3.5 supports in the form of boxes they are molded in a piece 3.10 zippers, which mesh respectively with a cogwheel, which is joined together swivel to a silicone brake 3.12. Silicone brakes 3.12 cause a delayed, smooth backward movement of the element of command 3.1, 3.2 in the form of a button assigned from the position of drive corresponding to the normal position (position of departure), causing the recoil movement by force of recoil of compressed helical springs during actuation of the control element 3.1, 3.2. Silicone brakes 3.12 with the sprockets assigned to the zippers 3.10 are housed in brackets 3.13, which can be interlocked by heels of interlocking 3.20 in recesses 2.20 in the form of windows of the cover 2.

The control elements 3.1, 3.2 have, respectively, a flat, substantially rectangular front side 3.14, 3.15, which laterally becomes a continuous peripheral core 3.16, 3.17, protruding backwards. The peripheral souls 3.16, 3.17, that is, the side surfaces of the control elements 3.1, 3.2, are made as closed surfaces (see Figures 9, 11, 14, 17 and 18). Both in the normal position and in an actuation position, the control elements 3.1, 3.2 cover with their peripheral souls 3.16, 3.18 the section 2.2 in the form of a cuvette of the cover 2, so that in particular the sliding rods 3.3, the zippers, 3.10, the silicone brakes 3.12 and the coil springs are not visible from the outside (see in particular figures 9, 11 and
14).

The two-part cover 1, 2 is provided with a frame-shaped screen 4, which is made very flat or thin and presenting a 4.1 flat front side. Laterally, the screen 4 has a small peripheral core 4.2 protruding backwards, whose depth corresponds to the thickness of section 1.1 in the form of a flange of the base frame, that is, of the First part 1 of cover 1, 2 of two parts. In the state mounted on the drive device, the narrow side of the section 1.1 flange-shaped cover 1 is therefore completely covered by screen 4.

In the embodiment shown here, the screen 4, which is preferably made of plastic or metal, It is made substantially rectangular. On his side later presents four sleeves 4.3, which are assigned to the centering elements 2.6 in the form of bolts of the second cover 2 and that can be inserted into these. In sleeves 4.3 they can screw on fixing screws (not shown) from the side rear cover 2.

The centering element drill 2.6 is staggered at the rear end, so that the drill presents there a reduced diameter (see fig. 8). The sleeves 4.3 of the screen 4 preferably have an internal thread, in which corresponding threaded bolts can be screwed on (no shown).

The maximum displacement of the elements of command 3.1, 3.2 in the direction of deck 2 is limited by the depth of their peripheral souls and the depth of the step interior in section 2.2 in the form of a cover bucket 2. As can be seen in figures 3, 9 and 11, the depth of the soul corresponding peripheral 3.16, 3.17 is sized in such so that, when the peripheral soul is seated on the step interior 2.10 of section 2.2 in the form of a bucket of cover 2, the front side of the control element 3.1, 3.2 still protrudes a little outward from the front side of the screen 4 in frame shape.

According to the invention, the two control elements 3.1, 3.2 are provided on the front side of pressing plates 5.1, 5.2, protruding laterally from the surfaces laterals defined by peripheral souls 3.16, 3.17 of the control elements 3.1, 3.2 so that in the normal position represented in figure 4 an impression is obtained as if the 5.1, 5.2 push plates will float in front of the wall or screen 4. The major 3.1 control element, with the 5.1 major pulse plate, It is planned to release a full wash, while the 3.2 minor control element, with the 5.2 minor pulse plate, is intended to release a reduced wash.

Pulse plates 5.1, 5.2 are made flat and have a maximum thickness respectively 10 mm Its thickness is preferably located in the range of 4 mm to 8 mm. The front side of the pressing plates 5.1, 5.2 It is made smooth and flat.

In the embodiment shown, the Pulse plates 5.1, 5.2 are fixed by means of a threaded joint inside in control elements 3.1 and 3.2 However, the fixation can also be done by joining by glue.

Pulse plates 5.1, 5.2 are made preferably of a glass plate or a glass plate of moon, being able to be, in particular, a plate with treated surface, for example a glass plate or a moon glass plate matt or satin and / or coated. In particular, it can be provided that the glass plate is matt from the side rear or front and behind it is attached a opaque material. Pulse plates 5.1, 5.2 can also be matted from the back or front side as glass plates of Moon. In this way the flotation impression is reinforced, since that in this way the user cannot visually detect the fixing on the back side of the glass plate or plate of moon glass in the control element 3.1 or 3.2 correspondent.

In figures 2, 4 and 7, which represent the normal position (starting position) of the control elements 3.1, 3.2, it can be seen that the pressing plates are separated one of another by a slit F and that each of the plates of pressing 5.1, 5.2 protrudes laterally with respect to the lateral surface (3.16, 3.17) of the corresponding 3.1 or 3.2 control element, the distance between the narrow sides being greater 5.11, 5.12, 5.21, 5.22 that do not limit the slit F of the pulse plate 5.1, or 5.2 corresponding and the lateral surface of the control element 3.1 or 3.2 that is assigned in its normal position that the distance between the back side of the 5.1 or 5.2 push plate and the side front 4.1 of the screen 4.

In the embodiment shown, the height and width of the total front surface defined by the two substantially rectangular 5.1 and 5.2 pulse plates (total control area) correspond to the height or width of screen 4. The diagonal d of the total front surface, which it is formed by the push plate 5.2 of the control element 3.2 and the push-button 5.1 of the control element 3.1, therefore, so much, the same measure as the diagonal of the screen 4. No However, it is also within the scope of the invention to dimension the pressing plates 5.1 and 5.2 such that the diagonal d of the total front surface defined by them (surface total command) is greater than the diagonal of screen 4.
