Description

The invention relates to a device for starting the discharge armature of a cistern according to the features specified in the introductory part of patent claim 1.

From the German model according to DE 93 16 824 U1, one such starting device is known with a housing in which a movable button is placed for activating the discharge armature of the cistern. The case is made in two parts and has an outer part of the case with one laid flange or frame on the upper side of the cistern cover. The upper part of the housing has, moreover, a mostly cylindrical body, which protrudes through the hole of the cistern cover into the interior of the cistern and has an external thread. In the interior of the cistern, there is also a lower part with a pot-shaped body, the inner thread of which is screwed to the outer thread of the cylindrical extension of the upper part. The lower part of the button and trigger housing has bearing and mounting elements for the actuation lever and, furthermore, has connecting elements of the adjustment sleeve, which houses the movable adjustment rod. The manufacture and assembly of a device of this type requires significant costs, especially if the said adjustment sleeve is connected to the lower part and the starting rod hangs. If operations are required to maintain the repair, then disassembly without difficulty is impossible, and when lifting the cistern cover, the risk of damage to the starting device and/or the entire discharge fitting cannot be ruled out.

Furthermore, an actuation device is known from the German model according to DE 91 10 092 U1 for a cistern discharge valve, which also has a button housing made of two parts. The upper part, which is mainly placed on the upper side of the cistern cover, has one guide sleeve that protrudes through the opening on the cistern cover into the interior of the cistern and has an external thread. From the inside to the outside, a nut with a thread is attached to the outer thread of the guide sleeve with a screw connection, which fixes the upper part on the lid of the cistern. A generally cylindrical rod is connected to the start button, i.e. the start button, which passes through the specified threaded sleeve. The upper part of the button bush stands at a relatively large distance above the outer upper surface of the cistern cover and is exposed to the risk of damage. The opening for the threaded bushing of the button housing provided in the lid of the cistern has a relatively small diameter and the enlargement of the part of the housing that protrudes inwards, i.e. the leading bushing with regard to the screw connection, is not possible without difficulty.

Finally, a starting device is known from the German model according to DE 92 10 440 U1, whose service button inside the cistern is connected to levers that are connected to the valve body of the discharge armature. During assembly, a solid connection should be made between the service button and the lever of the discharge armature, and for carrying out maintenance and repairs, the connection between the service button and the lever should be loosened. The lid of the cistern is placed above the body of the cistern, which can be filled with water in a known manner. The kettle is built for surface mounting and the lid with the service button is freely accessible from above. The starting device cannot be used without difficulty in a cistern that is built only for flush mounting. For flush mounting, a modified, customized version of the starting device is required, which is associated with corresponding production and installation costs.

Starting from this, the task of the invention is based on further improving the starting device, so that with a simple construction, simple assembly and disassembly can be carried out. The starting device should be able to be used without difficulty both in above-lipped and under-lipped cisterns. Furthermore, the expensive connection means between the operating button and the discharge fitting must be dispensed with.

The solution to this task is carried out according to the indicated features of patent claim 1.

The proposed starting device is characterized by a functionally reliable construction and enables universal use, both for surface-mounted and under-surface cisterns. The service button, primarily two service buttons, are located in a case made as an insert and together with it form a previously manufactured extension group. The cartridge with at least one service button is placed in the receiving part of the cover and protrudes into the inner space of the cistern, i.e. the cover. The receiving part has a purposefully inwardly directed extension in the said inner space, which is at least partially made ring-shaped. The above-mentioned extension has one recess which is larger than the thickness of the wall in the area of its opening by a previously specified factor. The receiving part and/or the extension extend from the inner surface of the cover into the predetermined depth of the inner space surrounded by the cover. The size of the inner surface of the receiving part can therefore be determined in advance according to needs, so that the insole with its outer surface sits firmly and/or mostly without airiness on the inner surface. The connection between the insert and the lid of the cistern, especially its receiving part, is built primarily as a mechanical one. Furthermore, the insert is placed primarily depending on the type of pressure fit in the receiving part of the cistern cover, whereby the surfaces of the insert, which lie on top of each other, are made with a mutually adapted overlap. The insert and/or the receiving part are purposely made of plastic, and taking into account the elasticity of that plastic, the exact fit can be determined beforehand without difficulty.

In order to enable a defined alignment of the insert after being pushed into the lid, the insert preferably has a stop, especially in the form of a flange located in the area of the outer surface of the lid.

Furthermore, the surface of the insert, which can be seen from the outside, is placed essentially flush with the outer surface of the lid. This also applies to the surface of at least one key. The insert with at least one service button must only be pressed into the receiving part as an easily exchangeable module and for carrying out maintenance or similar operations it can be removed in the opposite direction without difficulty. Although the solid connection of the insert with the receiving part and/or the cover of the cistern proved to be particularly expedient, the scope of this invention also includes wedged connections, for example with a clip or incised elements.

At least one service button is placed in the cartridge in a purposefully linearly movable manner and the cartridge contains a guide for linearly guiding the service button and/or one activation element connected to the service button. The actuating element, which is purposely designed as a bolt, is particularly firmly connected to one connecting element, the connecting part being arranged and located alone in the cistern. By pressing the service button, the activation element acts only through the force of the connection on the connecting part, through which the valve of the discharge armature is opened or closed. The connecting part can be made, for example, as a handle or a similar hinged lever on the bridge in the cistern, on which the free end of the activation element, i.e. the bolt, comes into position and which, by pressing the service button, is rotated in the required way to open or close the valve of the discharge fitting . During assembly, you only need to put the cistern cover on the cistern or connect it to it in a different way, whereby at least one service button is automatically connected to the connecting part. Hanging or making a different closing connection of the service button with the associated elements of the cistern is not necessary. The start-up device made as a separate add-on element according to the invention can be provided for cisterns of different constructions, whereby above all we want to point out above-lipped cisterns on the one hand and under-lipped cisterns on the other.

Further embodiments and special constructions of the invention are listed in the subclaims and will be explained in more detail in the following description of an exemplary embodiment.

In the following, the invention will be explained in more detail using an exemplary embodiment shown in the drawings, whereby

figure 1 shows a section of the disassembled starting device with the cistern cover,

figure 2 shows the assembled starting device from figure 1,

picture 3 shows the disassembled cover of the cistern for vertical installation together with the plaster cistern,

Figure 4 shows the disassembled horizontal cistern cover of the plaster cistern.

Figure 1 shows a cross-section of the cistern lid 2 with a wall thickness of 3 and with a receiving part 4, which is made primarily as an annular extension 5 directed into the inner space of the lid 2. Within the scope of the invention, the extension 5 does not have to be completely annular in circumference, but can have slots and/or may be partially interrupted. The receiving part 4 is used to receive the insert 6 in the opening 7 of the cover of the cistern 2, whereby this opening 7 is closed laterally, i.e. bordered on the side by the receiving element 4. As will be explained later, the cover of the cistern 2, together with the insert 6, according to figure 1, it can be placed vertically or also in a horizontal position, thus rotated by 90°. The receiving part 4 has an inner surface 8 and protrudes into the depth 9 over the inner surface 10 of the cover 2 into the inner space 11. On the inner surface 8 of the receiving part 8, the outer surface 12 of the insert 9 is adjusted in such a way that the insert can be pushed with a tight fit into the receiving part. part 4 and hold firmly. The receiving part 4 is arranged on the edge 13 of the opening of the lid 7 and protrudes from the edge 13 into the inner space 11. The lid of the cistern 2 and/or the insert 6 are purposefully made of a polymer material which, on the basis of its spring elasticity, enables a firm and locked insertion and placement of the insert 6 If, for example, the mentioned surfaces 8 and 12 are cylindrical, then the inner diameter of the inner surface 8 is smaller than the outer diameter of the outer surface 12 of the insert 6 by a previously determined value.

When assembling, the insert 6 is pushed in the direction of the arrow 14 with sufficient pressure into the receiving part 4 and thus the inner space 11, whereby no additional measures for fastening, such as screw fastening from the inside, are required. The cartridge 6 is pulled out in the direction opposite to the arrow 14, where only the appropriate force must be applied, and a tool as simple as for loosening additional screws, connecting means or the like is required. In order to allow a defined setting of the insert 12 in the lid of the water tank 2, the insert 12 has a stop 15, which is made primarily as a smaller ring flange. The limiter, i.e. the flange 15 engages first of all in the annular depression 16 of the lid of the cistern 2. The limiter 15 and the corresponding depression 16 are made and arranged primarily so that the outer surface of the insert 6 rests almost necessarily with the surface 18 of the lid of the cistern 2. For the correct adjustment of the insert 6, it contains a small support 19 which engages in the corresponding slot 20 of the receiving part 4, i.e. the lid of the cistern 2. As can be seen, the depth of the recess 16 on the flange 15 is adjusted. Regardless of the specific construction, the receiving part 4 and/or the lid of the cistern 2 has a boundary surface for the exact adjustment of the insert 6, and according to Figure 1, this boundary surface is made primarily as a recess 16 for the associated flange 15.

In the insert 6, two service buttons 21, 22 are provided for starting the rinsing, that is, for stopping it. Both buttons 21, 22 can, if necessary, be moved linearly in the insert 6 in the direction of the arrow 14 by manual activation.

The buttons 21, 22 are partially, preferably one-piece, connected to a single actuation element 24, 26, which are purposely made as a bolt and are therefore indicated as such. The insert 6 in the bottom 32 has axial guides 28, 30 for the studs 24, 26. The studs 24, 26 purposely do not have a cylindrical cross-section, but they have a polygonal cross-section and are made in accordance with the inner surface of the guides 28, 30. This enables the pivoting securing of the studs. 24, 26 and finally service keys. The elements for starting, i.e. the bolts 24, 26 protrude with their free ends over the bottom 32 into the intermediate space 11. The free ends of the bolts 24, 26 are made as notched elements 34, 36 so that the keys 21, 22 can be inserted into the corresponding bolts 24, 26 cartridge 6, whereby the notched bodies 34, 36 are pushed all the way using the guides 28, 30. The free ends of the bolts 24, 26 have at least one notch 38, 40, at least in the area of the notched elements 34, 36, which when inserted using the axial guides 28, 30 obviously enables the joint insertion of the notched elements 34, 36. If the bolts 24, 26 are pushed all the way in the manner shown, then the notched body 34, 36, made elastically enough, again occupies its shown position due to its increased diameter, i.e. the notched surface on its rear surface enable the adjustment of the service buttons 21, 22 in the insert 6.

Figure 2 shows the starting device in the assembled state, according to which the cartridge 6 is built as a module and is anchored in the receiving part 4 of the cistern cover 2. The externally visible outer surface 17 of the cartridge 6 is mainly connected to the outer surface 18 of the cistern cover 2. As long as the serviceable buttons 21, 22 are in their zero position, according to Figure 1, their outwardly directed surfaces 41, 42 are mostly connected to the outer surface of the cistern cover 2. To start the flushing process, for example, the service button 21 is pressed into the position shown, whereby the functional parts located in the inner space of the cistern are activated and are not further shown here. Schematically indicated, for example, is the connecting part 43 in the form of a lever, which is located in the cistern so that it can be rotated around an axis 44 perpendicular to the plane of the drawing. The bolts 24, 26 are not firmly connected to the connecting part, i.e. the lever 42, but the bolts 24, 26 are brought with their free ends only to rest against the lever 43 with two levers. One service button 21 is shown in the depressed position, in which the flushing procedure is initiated. At the same time, the second service button 22, which should also be shown as a stop button 22, moves out in the opposite direction from the lid of the cistern 2. Flushing can, if necessary, be interrupted by pressing the service or stop button 22 in the direction of the arrow 14.

The keys 21, 22 have side surfaces 45, 46, which abut the inner guide surface 47 of the cartridge 6 with sufficient clearance. material. Also, when pushing or pressing the buttons 21, 22 more forcefully, there is no need to fear that the above-explained bolts or driving elements, as well as their corresponding axial guiding parts, will be damaged. The cartridge 6 and the keys 21, 22 which can be moved axially in it, can be made without difficulty with a large surface, and/or according to the needs, and there is no need to adhere to the limitations of dimensioning or shaping.

Figure 3 shows in perspective the separate cover of the cistern 2 with a vertically placed cistern 48. This is a plastered cistern 48, on the front side of which a lining and/or ceramic tiles are placed in a known manner after assembly, whereby the control opening remains free, and which corresponds to the opening 49 at the upper end of the cistern 48. The opening 49 can be closed using the lid of the cistern 2, which can be removed if necessary, in order to reach the parts placed in the inner space of the cistern 48, such as the discharge fitting with valve, and the inlet valve. In the region of the opening 49 there is a connecting part, which is not shown here. On the front side of the lid of the cistern 2, both service buttons 21, 22 of the insert 6 can be seen. The outer contour of the insert 6 in this embodiment is oval, however, within the scope of this invention, the insert, as well as the service buttons 21, 22, can be of different shapes or sizes. .

Figure 4 shows a further embodiment, in which the lid of the cistern 2 is placed horizontally above the cistern 48. Between the cover of the cistern 2 and the upper side 50 of the cistern 48, a horizontal plate or lining can be placed in a known manner, which is purposely nailed. The opening 49 of the cistern 48 is located in the area of the horizontally placed upper side 50 of the cistern 48 and after removing the cover of the cistern 2 there is free access to the interior of the cistern 48.
