EP2525003B1 - Adapter for cleaning a siphon or drainage pipe connected to a floor drainage tray, in particular a shower tray - Google Patents

Description

The invention relates to a use of an adapter in combination with a rubber bell having a suction cup for the removal of blockages in a drain, wherein the adapter has a plugged into a drain pipe socket, the lateral surface acts as a sealing surface opposite the drain pipe or is provided with a sealing ring, said the adapter has an adapter plate which projects radially beyond the pipe socket, has an opening into the pipe socket opening and is connected liquid-tight with the pipe socket, and wherein the adapter plate is designed so that the rubber bell pressure-tight or suction-tight can sit on the adapter plate and depress ,

In sanitary drain pipes or siphons of sinks, bathtubs and sinks, for example, by dirt particles, hair and other deposits blockages occur. To eliminate such blockages usually a suction cup (colloquially referred to as Pümpel) is used. A suction cup is known to consist of a rubber bell, which is usually attached to the end of a wooden rod. By the suction cup sealingly arranged on the inlet opening of the plugged drain pipe and then both positive and negative pressure is generated, blockages in the drain pipe or siphon can be eliminated. Alternatively or additionally, caustic pipe cleaning agents are also used liquid or granular form used to dissolve blockages in sanitary drainage pipes or siphons.

However, many existing sanitary floor drains, in particular gutters and shower channels are relatively long and narrow. A commercial suction cup (Pümpel) can not be effectively used in such Bodenabläufen usually because the rubber bell due to their dimensions, the inlet opening of the drain pipe or siphon does not cover sealing. Although caustic pipe cleaners may be used to remove clogs in such floor drains, these pipe cleaners are not harmless to the user due to their caustic effect, are relatively expensive, and in many cases pollute the environment.

The EP 0 233 961 A1 describes a suction cup (Pümpel) for a toilet bowl. Alternatively, the suction cup can also be used for sinks, sink drains or bathtub drains. The suction cup has a rubber bellows made of elastic, flexible rubber or plastic, to which a sealing element is attached. The sealing element can be understood as an adapter and comprises a plate and a pipe socket, which can be plugged sealingly into the outlet nozzle of the process. The rubber bellows is cylindrical and hollow.

The US 2010/0132102 A1 discloses a suction device for cleaning a sewer pipe. The device comprises a manually operable piston pump with a cylindrical pump housing and a replaceable rubber-made spout.

The US 4,238,860 discloses a device for cleaning a sewer, which has a cup-shaped, rubber-bell-like cover for connection of a pressurized water hose. In one embodiment the cover on its underside with an adapter in the form of an approximately pear-shaped hollow body having two open ends and is made of rubber. The adapter is screwed to the cover via a threaded connector.

The present invention has for its object to provide a comparatively inexpensive device and their use, can be effectively eliminated by using a suction cup blockages in a drain pipe or siphon a shower channel or narrow floor drainage channel.

This object is achieved by the use of an adapter in combination with a suction cup according to the features indicated in claim 1.

The adapter used in this case comprises a pipe socket which can be inserted into a drain neck of the floor gutter and whose lateral surface acts as a sealing surface opposite the drain neck or is provided with a sealing ring, and an adapter plate which radially projects beyond the pipe neck, has an opening opening into the pipe neck and has an opening Pipe socket is connected liquid-tight.

The pipe socket of the adapter can be inserted sealingly into the drainage socket of the floor drainage channel or shower channel on the outside of the pipe. Subsequently, the rubber bell of a commercially available suction bell (Pümpel) can be put pressure-tight or suction-tight on the adapter plate of the adapter according to the invention and depress. If necessary, the drain area will then still be supplied with additional water so that the clogged drain is flooded during the subsequent short lifting of the rubber bell. By rapid movement up and down of the Saugglockenstabes a vacuum is generated by means of the suction cup, through which a blockage can be solved in the attached to the gutter or shower drain pipe or siphon, so that the clogging causing hair and / or deposits in the direction let press a portion of the drain pipe having a larger inner diameter.

The adapter can be produced relatively inexpensively, preferably by injection molding of plastic. The core of the invention is that the adapter plate is provided on the underside with a tubular connecting piece, which is connected liquid-tight and axially adjustable with the pipe socket or connectable. The tubular connecting piece and the pipe socket together form a telescopic tube. This allows an optimal adaptation of the adapter to differently deep running gutters, especially shower channels. A different gutter depth can result from differently dimensioned gutter bodies and / or differently thick floor tiles or natural stone slabs which overlap a peripheral flange of the gutter body.
The connection piece preferably has a sealing ring at its end associated with the pipe socket. As a result, with easy to be executed axial adjustability of Connecting stub relative to the insertable into the outlet nozzle of the floor drainage channel (shower channel) pipe socket achieves a reliable sealing effect between the connection piece and pipe socket of the adapter.

An axial adjustability of the connecting piece relative to the pipe socket and a reliable sealing effect between connecting pieces and pipe socket can be advantageously realized in particular by the fact that the pipe socket of the adapter according to the invention has a sleeve-like connecting portion according to a preferred embodiment, in which an end portion of the connecting piece can be inserted.

The adapter has at the outlet nozzle of the floor drainage channel (shower channel) associated with the end of the pipe socket to an oval cross-section. The adapter is intended for particularly narrow trained floor drainage or shower channels, the drain pipe has an oval shaped cross-section to allow despite narrow channel width nonetheless a high drainage capacity of the floor drain or shower channel. The width of the oval end of the pipe socket, i. The shorter outer dimension of the oval pipe socket is for example in the range of about 4 cm to about 1.5 cm, in particular in the range of about 3 cm to about 1.5 cm.

In this context, a further embodiment of the adapter with respect to its preferred telescopic design provides that the sleeve-like connecting portion of the pipe socket and the therein insertable end portion of the connecting piece have oval cross-sections formed.

A further advantageous embodiment is in terms of narrow floor drain or shower channels, the drain pipe has an oval cross-section, in that the outlet spigot associated end of the pipe socket and the socket-like connecting portion of the pipe socket have substantially continuous in each other passing broad sides, and that the sleeve-like connecting portion the end of the pipe socket assigned to the discharge nozzle of the floor drain or shower channel projects in a stepped manner on its narrow sides. As a result, the limited space in the narrow channel optimally used to use a relatively wide pipe socket and thus a relatively high suction by means of a suction cup for cleaning the drain pipe connected to the gutter or siphon can be achieved. In order to achieve a relatively large axial adjustment range of the telescopically formed adapter, a further preferred embodiment of the invention provides that the height of the sleeve-like connecting portion is at least twice the height of the outlet nozzle of the floor drain associated end of the pipe socket.

The adapter is characterized by a high breaking strength with comparatively low weight or material consumption, if, according to a further preferred embodiment, reinforcing ribs are formed on the underside of the adapter plate.

The stability of the adapter is improved according to a further preferred embodiment, characterized in that the pipe socket has at least one transverse strut on the inside at its end which can be inserted into the outlet nozzle of the floor drainage channel. In the preferred telescopic design of the adapter according to the invention, the connection piece can also have at least one cross-bracing on the inside at its end associated with the pipe socket.

For ease of handling of the adapter, in particular for easy insertion of the pipe socket in the outlet connection of the floor drainage channel, it is favorable if, according to a further preferred embodiment of the adapter, the pipe socket has a bevelled peripheral edge at its end which can be inserted into the drainage nozzle of the floor drainage channel. Accordingly, in the preferred telescopic design of the adapter and the connecting piece at its end associated with the pipe socket have a beveled peripheral edge.

Further preferred and advantageous embodiments of the inventive use of the suction cup in combination with the adapter are specified in the appended subclaims.

The illustrated adapter 1 serves as a cleaning aid for a sanitary floor drainage channel, in particular a shower channel. The floor drainage channel has a drain neck which is substantially oval in cross-section and to which a drainage pipe and / or a siphon (odor trap) is connected (not shown).

The adapter 1 comprises a pipe socket 1.1 which can be inserted into the outlet connection of the floor drainage channel. The end of the pipe socket 1.1 assigned to the outlet nozzle of the floor drainage channel has a substantially oval cross-section. In the lateral surface of the pipe socket 1.1, a circumferential annular groove 1.11 is formed, in which an annular seal 1.12, preferably used or held a rubber-elastic O-ring is. The seal or the O-ring 1.12 protrudes with respect to the outer surface (lateral surface) of the pipe socket 1.1.

Furthermore, the adapter 1 comprises an adapter plate 1.2, which has an opening in the pipe socket 1.1 opening 1.21. The opening 1.21 is formed substantially slit-shaped. The adapter plate 1.2 may be integrally formed at the upper end of the pipe socket 1.1. In the embodiment shown in the drawing, however, the pipe socket 1.1 and the adapter plate 1.2 are formed as separate parts, wherein on the adapter plate 1.2 on the underside a tubular connecting piece 1.22 is attached, the liquid-tight and axially adjustable with the pipe socket 1.1 is connectable. The connecting piece 1.22 of the adapter plate 1.2 is inserted for this purpose in the pipe socket 1.1. The pipe socket 1.1 has a sleeve-like connecting portion 1.13, in which an end portion of 1.221 of the connecting piece 1.22 can be inserted. The sleeve-like connecting portion 1.13 of the pipe socket 1.2 and the end portion 1.221 of the connecting piece 1.22 which can be inserted therein also have essentially oval cross-sections.

The outlet spout of the floor gutter associated end of the pipe socket 1.1 and the socket-like connecting portion 1.13 of the pipe socket 1.1 have substantially infinitely merging broadsides 1.110, 1.131, while the socket-like connecting portion 1.13 the outlet nozzle of the bottom gutter associated end of the pipe socket 1.1 1.111 on its narrow sides stepped overhanging.

The height H _{1 of} the socket-like connecting portion 1.13 is at least twice the height H ₂ of the outlet nozzle of the bottom gutter associated end of the pipe socket 1.1 1.1. For example, the height H _{1 of} the sleeve-like connecting portion 1.13 can be 2.2 times to 4 times the height H ₂ of the end of the pipe outlet 1.1 associated with the outlet nozzle of the floor drainage trough.

At its end assigned to the pipe socket 1.1, the connecting piece 1.22 of the adapter plate 1.2 has a sealing ring 1.23. The sealing ring 1.23, which consists for example of a rubber-elastic O-ring, is preferably held in a circumferential annular groove 1.24, which is formed in the lateral surface of the connecting piece 1.22. The sealing ring 1.23 stands against the lateral surface of the connecting piece 1.22 something before, so that in the assembled state, a liquid-tight or suction-tight connection with the insertable into the outlet nozzle of the floor drain pipe socket 1.1 results.

The adapter plate 1.2 projects beyond the pipe socket 1.1 on the outside radially. When used as intended, the adapter 1, the adapter plate 1.2 engages over the vertical gutter walls of the floor drainage channel top side. The opening 1.21 of the adapter plate 1.2 which opens out into the pipe socket 1.1 or the connecting piece 1.22 is oval, in particular slot-shaped (cf. Fig. 4 ).

The adapter plate 1.2 is preferably formed substantially circular disk-shaped. Their diameter is in the range of 12 cm to 20 cm, preferably in the range of 14 cm to 20 cm. On its underside has the adapter plate 1.2 Reinforcement ribs 1.25 on. The reinforcing ribs 1.25 run partly crosswise. The upper side of the adapter plate 1.2 is substantially smooth, so that a suction bell (rubber bell) can be attached to the adapter plate 1.2 on the upper side in a substantially suction-tight manner.

The pipe socket 1.1 has at its insertable into the outlet nozzle of the floor drain trough end 1.14 inside a lattice-like cross bracing 1.15. Furthermore, in the Figures 2 and 3 to recognize that the outer peripheral edge 1.16 of the pipe socket 1.1 formed beveled at its plugged into the outlet nozzle of the floor drain trough end 1.14, for example, is provided with a circumferential chamfer.

The width B of the oval pipe socket 1.1, ie the shorter outer dimension of the pipe socket 1.1 is, for example, in the range of about 4 cm to about 1.5 cm, in particular in the range of about 3 cm to about 1.5 cm (see. FIGS. 4 and 6 ).

The connecting piece 1.22 of the adapter plate 1.2 has at its the pipe socket 1.1 associated end inside also a grid-shaped cross bracing 1.26.
