DESCRIPTION

Adapter for cleaning a siphonic canister or drain pipe connected to a floor drain channel, in particular to a shower channel

The invention relates to a use of an adapter in combination with a plunger that has a rubber suction cup to remove blockages in a drain, the adapter having a pipe joint that can be inserted into a drain joint, whose side surface acts as a surface sealing with respect to the drain joint or is provided with a sealing ring, the adapter presenting an adaptation plate, which protrudes radially on the outer side of the pipe joint, presenting an opening that flows into the pipe joint and being connected with the tube joint tightly to the liquids, and the adaptation plate being made in such a way that the rubber suction cup can be placed and pressed tightly to the pressure or tightly to the suction on the adaptation plate.

Obstructions can occur in sanitary sewer pipes or siphon boats, sinks and sinks, for example by dirt particles, hair and other depositions. To remove such obstructions, a plunger is usually used (colloquially also called destapacanos). As is known, a plunger consists of a rubber suction cup, which is usually placed at the end of a wooden bar. By arranging the plunger as a seal over the intake opening of the clogged drain pipe and then generating both overpressure and underpressure, blockages in the drain pipe or siphon canister can be eliminated. Alternatively or complementary, corrosive pipe cleaning agents are also used in liquid or granular form, to break up the obstructions in sanitary drainage pipes or siphonic boats.

However, many existing sanitary floor drains, in particular drainage gutters and shower gutters, are relatively long and narrow. A commercially available unclogger (destapacanos) cannot generally be used in such floor drains, since the rubber suction cup, due to its dimensions, does not tightly cover the inlet opening of the drain pipe or siphon boat Although, in order to eliminate obstructions in such floor drains, corrosive pipe cleaning agents can be used if necessary, these pipe cleaning agents are not without danger to the user due to their corrosive effect, they are relatively expensive and also in many cases involve a Charge for the environment.

EP 0 233 961 A1 describes a plunger (destapacanos) for a toilet bowl. Alternatively, the plunger can also be used for sinks, sink drains or bathtub drains. The plunger has a rubber or elastic and flexible plastic bellows, in which a sealing element is placed. The sealing element can be understood as an adapter and comprises an ace plate! as a pipe joint, which can be inserted tightly into the drain connection of the drain. The rubber bellows is cylindrical and hollow.

US 2010/0132102 A1 discloses a suction device for cleaning a sewage pipe. The device has a plunger pump that can be operated manually with a cylindrical pump housing and a replaceable nozzle, made of rubber.

Document US 4 238 860 discloses a device for cleaning a sewage pipe, which has a cup-shaped cover, of a rubber suction cup type, for connection to a flexible pressurized water pipe. In one embodiment, the cover is provided on its lower side with an adapter in the form of an approximately pear-shaped hollow body, which has two open ends and is made of rubber. The adapter is screwed through a threaded connection with the cover.

The present invention is based on the objective of indicating a comparatively economical device and its use, by means of which obstructions in a drain pipe or siphonic canister can be effectively removed from a shower gutter or narrow floor drain gutter using a plunger.

This objective is achieved by using an adapter in combination with a plunger according to the characteristics indicated in revindication 1.

The adapter used comprises a pipe joint that can be inserted into a drain joint of the floor drain channel, whose side surface acts as a sealing surface with respect to the drain joint or is provided with a sealing ring, and a plate of adaptation, which protrudes radially on the outer side of the tube joint, has an opening that leads to the tube joint and is connected to the tube joint tightly to the liquids.

The tube fitting of the adapter can be inserted tightly into the outer side of the tube in the drain connection of the floor drain channel or shower channel. Subsequently, the rubber suction cup of a plunger (destapacanos) customary in commerce can be placed and tightened in a tight manner to pressure or suction on the adapter adaptation plate according to the invention. If necessary, then supplied

even additional water to the drainage area, so that after briefly raising the rubber suction cup, the clogged drain is flooded. By means of a rapid up and down movement of the plunger bar, a sub-pressure is generated by means of the plunger, by means of which an obstruction in the drain pipe or siphonic canister connected to the drain channel or shower channel, of so that hair and / or stools that cause blockage can be pushed towards a section of the drain pipe that has a larger internal diameter.

The adapter can be produced relatively inexpensively, preferably by injection molding from plastic. The core of the invention is that the adaptation plate has to be provided on its lower side with a tubular connection joint, which is attached or can be tightly connected to the liquids and axially movable with the tube connection. The tubular connection joint and the tube joint together form a telescopic type tube. This enables an optimal adaptation of the adapter to floor drain channels configured with different depths, in particular shower channels. A different gutter depth can be obtained by gutter bodies of different dimensions and / or by natural stone tiles or slabs of different thicknesses, which overlap with a surrounding flange of the gutter body. In this regard, the connection joint preferably has a sealing ring at its end associated with the tube connection. Thus, in the case of an axial displacement capability that must be performed in a simple manner of the connection joint in relation to the pipe joint that can be inserted into the drain connection of the floor drain channel (shower channel) a reliable sealing effect is achieved between the connection splice and the adapter tube splice.

An axial displacement capacity of the connection splice in relation to the tube splice and a reliable sealing effect between the connection splice and the tube splice can be advantageously implemented in particular because the splice fitting of the adapter according to the invention presents according to a preferred configuration is a sleeve-type connection section, in which an end section of the connection joint can be inserted.

The adapter has at the end of the tube connection associated with the drain connection of the floor drain channel (shower channel) an oval shaped cross section. The adapter is intended for floor or shower drain channels configured in a particularly narrow way, whose drain connection has an oval shaped cross-section so that, despite a narrow channel width, it also allows a high drain performance of the floor or shower drain channel. The width of the oval end of the tube joint, ie the shortest outer measure of the oval tube joint is for example in the range of from about 4 cm to about 1.5 cm, in particular in the range of from about 3 cm up to approximately 1.5 cm.

In this context, an additional configuration of the adapter with respect to its preferred telescopic type configuration foresees that the sleeve-type connection section of the pipe joint and the end section that can be inserted therein of the connection joint have cross-sections configured. oval

An additional advantageous configuration consists in the narrow floor or shower drain channels, whose drain connection has an oval shaped cross-section, in which the end of the pipe joint associated with the drain connection and the connection section The sleeve type of the tube connection has essentially wide sides that pass gradually to each other, and that the sleeve-type connection section protrudes as a step of the end of the tube connection associated with the drain connection of the floor drain channel or shower on its narrow sides. In this way, the limited space in the narrow gutter can be used optimally for the insertion of a relatively wide pipe joint and thereby achieve a relatively high suction action by means of a plunger for cleaning the drain pipe or siphonic canister. connected to the gutter. In order to achieve a relatively large axial displacement range of the telescopically configured adapter, a further preferred configuration of the invention provides that the height of the sleeve-type connection section is at least twice the height of the end of the pipe joint associated with the drain connection of the floor drain channel.

The adapter is characterized by a high resistance to breakage with a comparatively reduced weight or consumption of material, when according to an additional preferred configuration on the lower side of the adapter plate reinforcement ribs are configured.

The stability of the adapter is improved according to an additional preferred configuration because the tube joint has at its end that it can be inserted into the drain joint of the floor drain channel on its inner side at least one transverse brace. In the case of the preferred telescopic configuration of the adapter according to the invention, the connection joint can also have at least one transverse brace at its associated end to the tube joint on its inner side.

For a simple handling capacity of the adapter, in particular for a simple insertion capacity of the pipe joint in the drain connection of the floor drain channel, it is favorable that according to an additional preferred configuration of the adapter the pipe joint present in its end that can be inserted into the drain joint of the floor drain channel a beveled edge edge. Therefore, in the case of the preferred telescopic configuration of the adapter, the connection joint can also have a beveled edge edge at its associated end to the tube joint.

Additional preferred and advantageous configurations of use according to the invention of the plunger in combination with the adapter are indicated in the attached dependent claims.

Next, the invention will be explained in more detail by means of drawings that represent an example of embodiment. They show:

Figure 5, the tube joint of Figure 2, in a side view; Y

Figure 6, the tube joint of Figure 2, in a bottom view.

The adapter 1 shown serves as a cleaning accessory for a sanitary floor drain channel, in particular a shower channel. The floor drain channel has an essentially oval shaped drain joint in cross section, to which a drain tube and / or a siphonic canister (toilet siphon) is connected (not shown).

The adapter 1 comprises a tube connection 1.1 that can be inserted into the drain connection of the floor drain channel. The end of the tube connection 1.1 associated with the drain connection of the floor drain channel has a cross section essentially oval shaped. A surrounding annular groove 1.11 is formed on the lateral surface of the tube joint 1.1, into which an annular seal 1.12, preferably a toric seal with rubber elasticity, is inserted or secured. The gasket or toric gasket 1.12 protrudes with respect to the outer surface (lateral surface) of the pipe joint 1.1.

Moreover, the adapter 1 comprises an adaptation plate 1.2, which has an opening 1.21 that leads to the tube connection 1.1. The opening 1.21 is essentially formed in the form of a slit. The adapter plate 1.2 may be formed in one piece at the upper end of the tube joint 1.1. However, in the exemplary embodiment shown in the drawings, the tube connection 1.1 and the adaptation plate 1.2 are configured as separate parts, a tubular connection connection 1.22 being placed in the adaptation plate 1.2 on its lower side, which It can be connected tightly to liquids and axially displaceable with tube connection 1.1. The connection junction 1.22 of the adapter plate 1.2 is inserted into the tube connection 1.1. The tube joint 1.1 has a sleeve section 1.13, in which an end section 1.221 of the connection joint 1.22 can be inserted. Also, the sleeve-type connection section 1.13 of the tube connection 1.2 and the end section 1.221 which can be inserted therein in the connection connection 1.22 have cross sections configured in an essentially oval manner.

The end of the tube connection 1.1 associated with the drain connection of the floor drain channel and the sleeve-like connection section 1.13 of the tube connection 1.1 have wide sides 1,110, 1,131 that essentially pass gradually to each other, while that the connecting section of the sleeve type 1.13 protrudes as a step of the end 1.14 of the tube connection 1.1 associated with the drain connection of the floor drain channel on its narrow sides 1,111.

The height H1 of the sleeve-type connection section 1.13 amounts to at least twice the height H2 of the end 1.14 of the pipe joint 1.1 associated with the drain connection of the floor drain channel. For example, the height H1 of the sleeve-type connection section 1.13 may be 2.2 times to 4 times the height H2 of the end 1.14 of the pipe joint 1.1 associated with the drain connection of the floor drain channel.

At its end associated with the pipe joint 1.1, the connection joint 1.22 of the adapter plate 1.2 has a sealing ring 1.23. The sealing ring 1.23, consisting for example of a toric joint with

rubber elasticity, is preferably fastened in a surrounding annular groove 1.24, which is configured on the lateral surface of the connection splice 1.22. In this regard, the sealing ring 1.23 protrudes a little with respect to the lateral surface of the connection junction 1.22, so that in the inserted state a tight connection to the liquids or tight to the suction is obtained with the tube connection 1.1 which can be inserted into the drain joint of the floor drain channel.

The adapter plate 1.2 protrudes radially on the outer side of the tube joint 1.1. In the case of an intended application of the adapter 1, the adaptation plate 1.2 extends above the upper side of the vertical gutter walls of the floor drain channel. The opening 1.21 of the adapter plate 1.2 leading to the pipe joint 1.1 or the connection joint 1.22 is oval shaped, in particular in the form of a groove (see Figure 4).

The adapter plate 1.2 is preferably configured essentially in the form of a circular disk. Its diameter is in the range of from 12 cm to 20 cm, preferably in the range of from 14 cm to 20 cm. On its lower side, the adaptation plate 1.2 has reinforcement ribs 1.25. The reinforcement ribs 1.25 run partly in a cross. The upper side of the adaptation plate 1.2 is configured essentially flat, so that a plunger (rubber suction cup) can be placed essentially in a suction tight manner in the adaptation plate 1.2 on its upper side.

The pipe joint 1.1 has at its end 1.14 that a transverse brace can be inserted into the drain side of the floor drain channel on its inner side 1.15. In addition, in Figures 2 and 3 it can be recognized that the outer edge perimeter edge 1.16 of the tube joint 1.1 at its end 1.14 that can be inserted into the drain joint of the floor drain channel is bevelled, for example It is equipped with a surrounding chamfer.

The width B of the oval tube joint 1.1, ie the shortest outer measure of the tube joint 1.1 is for example in the range of from about 4 cm to about 1.5 cm, in particular in the range of from about 3 cm to approximately 1.5 cm (see Figures 4 and 6).

The connection junction 1.22 of the adapter plate 1.2 has, at its end, associated with the tube connection 1.1 on its inner side, also a transverse brace in the form of a grid 1.26. In Figures 1 and 3 it can be recognized that at the end of the connection junction 1.22 on the outer side a bevelled perimeter edge 1.27 or surrounding chamfer 1.27 is configured.
