Description

The invention relates to a connection of a water pipe with a filling valve for a cistern according to the preamble of claim 1.

Toilet flushing cistern filling valves are designed to regulate the flow of water into the cistern as a function of a cistern fill level limit. Among other things, float valves are known in which the water flow is controlled by a float. If the level falls below a certain level, the valve opens and closes again when the setpoint level is reached.

To connect a filling valve with a water house connection rigid lines are often provided which have a thread at its end facing the filling valve. At the filling valve, a nozzle is also provided with a thread, so that the connection between the line and filling valve is made by means of a union nut. Then the water pipe is firmly fixed to the filling valve. Due to the limited space in cisterns it can therefore come to constraints or flexible hoses to torsion.

From the EP 1 457 727 B1 For connection of water pipes with sanitary fittings hoses with a nipple are known, which are inserted or screwed into a receptacle of the sanitary fitting and fastened by a clamp on the sanitary fitting.

Against this background, the object of the invention is to improve a connection of a water pipe with a filling valve and to save costs in the manufacture and assembly.

This object is achieved by a valve cartridge having the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

To achieve the object, the invention provides a connection, preferably a plug connection of a water pipe with a filling valve for a cistern. The water pipe, which may for example be a fixed pipe or a flexible hose, has at its free end a first pipe socket.

In the region of this first pipe attachment to the water pipe, a first flange or collar is formed at least partially circumferentially. The diameter and the thickness of the collar or the flange are variable. Advantageously, the flange or collar is provided in portions of the pipe socket, which are offset by 180 ° to each other. Furthermore, a second pipe socket is arranged on the filling valve, which has a second flange or collar, which is also provided at least partially encircling. According to the invention, the first and second pipe socket are pushed into each other or one above the other in the manner of a socket-nipple connection. The two flanges or collars define the insertion depth of a pipe approach in the other pipe approach and thus serve as a stop.

For axial fixation of the connector of the pipe approaches a fuse element is provided with at least two angled legs surrounding the flanges or the collars of the first and second pipe socket. The connection between the fuse element and the flanges or collars of the pipe approaches is form-fitting.

Usually, the fuse element is made in one piece. The legs are integrally formed on a base plate, which has a passage opening for the pipe socket and have an essentially L-shape. This results between the base plate and the angled end a clear leg length. This free or clear leg length of the securing element corresponds to the sum of the thickness of the flanges or the collars of the first and second pipe socket. Since the pipe connections of the water pipe and the filling valve have no thread, the connection between the water pipe and filling valve after the nesting of the free ends of the pipe connections is not yet secured or secured. Since a tight connection between the two water-bearing components must be ensured, a corresponding fuse element must be arranged. The sealing of the connection is achieved by a radial sealing element on one of the pipe approaches. With the securing element ensures that the position of the two pipe approaches is fixed in the axial direction. In this case, the two flanges or collars of the water pipe and the filling valve may have a distance or a certain amount of play to each other. Thus, the water pipe is rotatably fixed by the securing element on the filling valve.

Alternatively, the two flanges or collars of the water pipe and the filling valve can be clamped or clamped together under a certain contact pressure.

An embodiment of the invention also provides that the securing element is designed in several parts. The individual parts can be connected to each other via a hinge or a joint. Furthermore, the securing element may consist of two half-shells or two U-shaped legs, which around the pipe socket and around mesh. In the latter embodiment can thus be dispensed with the base plate with the passage opening. Accordingly, it is possible to mount the securing element only after nesting of the pipe approaches.

Advantageously, the second pipe socket of the filling valve is provided as a sleeve and the first pipe socket of the water pipe as a nipple. Accordingly, the inner diameter of the pipe socket of the filling valve is equal to or greater than the outer diameter of the free end of the first pipe socket. The flange on the second pipe socket of the filling valve is thus arranged at its outer end, while the flange or collar is positioned offset on the first pipe socket of the water pipe to its free end. The flange of the filling valve may have a larger diameter than the flange of the water pipe.

An embodiment of the invention also provides that the flange of the filling valve has a rectangular contour. Thus, the legs of the securing element may be formed parallel to each other. At the pipe extension of the water pipe, a radial sealing element or a sealing ring is also arranged, which ensures in the region of interlocking pipe approaches for sealing to the outside.

With the compound according to the invention, on the one hand, the factory processing of the water pipes and the filling valve can be reduced, since no more threads must be provided at the free ends of the components. Furthermore, the union nut, which also had to be threaded, be replaced by a simple positive locking fuse element.

Further advantages arise during assembly, since the time required for screwing the nut can be saved. The fixing or jamming of the components via the fuse element takes place within a very short time. Another advantage of the compound according to the invention is that the water pipe is still rotatably mounted in or on the filling valve after assembly. Furthermore, the securing element is rotatably mounted on the water line. This means that the water pipe is still rotated in relation to this or to the filling valve even after attachment of the securing element. The water pipe can thus be mounted twist-free and even after attachment to the filling valve can still be aligned as needed in the cistern.

Advantageously, the legs of the securing element are provided elastically or resiliently. When mounting the connector, the legs of the fuse element are spread apart after nesting of the two pipe approaches. Subsequently, the securing element is moved or brought to the end or securing position. In this position, the leg or legs of the securing element are released, so that they return to their original position. In this end position, the legs of the securing element then surround the flanges or collars of the pipe connections of the water pipe and filling valve.

By means of a tool, they can be spread open again, so that the connection between the water pipe and filling valve can be released again.

An embodiment of the invention provides that the legs of the securing element each have a locking projection at their ends. Furthermore, the second pipe socket on the side facing away from the free end of the pipe socket side of the collar or flange locking recesses may have. Advantageously, the latching hooks and locking recesses may be provided barb-shaped. Due to the pending pressure in the water line, the compound secures itself by the interlocking of locking projections and locking recesses.

According to a variant of the compound according to the invention, this can also be provided insoluble. For this purpose, another collar or stop is placed behind the detent recess. The end of the leg of the securing element is thus mounted in a groove. There is no possibility to grip with a tool behind the locking projection and spread open the legs of the fuse element.

According to the invention, the two flanges or collars of the water pipe and the filling valve are only partially or segmentally arranged on the two pipe approaches. Advantageously, the flange segments are arranged offset by 180 ° on the pipe socket, so that the securing element can include these with two legs accordingly.

The invention will be explained in more detail using an exemplary embodiment and with reference to the drawing. Equivalent elements are identified in the figures with the same reference numerals. In detail, they show:

1 and 2 show the connection of a water pipe 10 with a filling valve 20 a cistern (not shown). The water pipe 10 is by means of a fuse element 30 at the filling valve 20 fixed.

Out 3 it becomes clear that the water pipe 10 , which consists of a flexible hose, at its free end a pipe socket 11 in the form of a nipple. Also on the filling valve 20 is a pipe socket 21 molded, this as a sleeve for receiving the pipe socket 11 the water pipe 10 is provided.

For tight connection of the water pipe 10 with the filling valve 20 is also on the pipe socket 11 the water pipe 10 an annular sealing element 13 intended. To limit the insertion depth is on the pipe socket 11 the water pipe 10 an annular collar or flange 12 arranged.

Like from the 3 to 5 can be seen, is on the pipe socket 21 of the filling valve 20 also a flange 22 arranged, which has a substantially rectangular contour. For axial securing of the water pipe 10 in the filling valve 20 became a security element 30 over the two flanges 12 . 22 pushed, with his two thighs 31 the flanges 12 . 22 includes and with its latching projections 32 ensures a deadlock. At the flange 22 of the filling valve 20 are several positioning aids 23 . 24 in the form of stop lugs 23 or a rib 24 arranged the position of the fuse element 30 determine. The lower thigh 31 has a slot, so that the securing element 30 over the rib 24 can be brought exactly to the desired clamping position. The stop noses 23 determine the position of the security element 30 laterally.

The connection shown is designed as an insoluble variant.

Out 4 it becomes clear that behind the flange 22 another covenant or stop 25 at the pipe socket 21 of the filling valve 20 is provided. The distance between the flange 22 and the federal government 25 is chosen so that the angled part of the leg 31 of the fuse element 30 or its locking projection 32 fits exactly into the groove, resulting from the arrangement of the two flanges 12 . 22 results. After locking the fuse element 30 it is no longer possible to release the connection.
