Description

Drain set for sinks or sinks.

The invention relates to a drain set for sinks or sinks, with a drain valve housing, a piece of drain pipe to be disposed on the bottom side of a sink or sink, which can be connected to the valve housing of drain, and a drive rod for actuating a valve body inserted in the drain valve housing, the piece of drain pipe presenting a pipe extending in the transverse direction relative to the vertical central axis, for guiding the actuator rod towards the valve body and another tubing being molded in the piece of drain pipe, which extends in the transverse direction with respect to the vertical central axis thereof and with which a drain bend is connected to liquids .

A drain set of this type is known from document CH 132550, which therefore represents the closest state of the art. The known drain set is provided in particular for washbasins and has a drain valve that can be operated by means of a linkage and a siphon housing arranged directly on the lower side of the washbasin. The part of the linkage that is in contact with the drain valve is made as a lever, which is housed by a two-part spherical joint in the siphon housing. Above the spherical linkage of the linkage, the siphon housing has a splice pipe for a drain pipe, raising the splice pipe up to keep as small as possible the difference in height between the sink outlet and the level of drain of the drain pipe.

The known drainage sets for washbasins usually have a relatively long intermediate pipe, which is connected in vertical extension below the piece of drain pipe provided with the actuating rod at the outlet end thereof and which flows into a toilet drain, with which the drain pipe itself is connected (see for example document DE 195 04 793 A1).

Drain kits whose valve bodies can be lifted from the valve seat by means of a drive linkage and which can be re-lowered to the valve seat have in principle given good results in practice. However, they have the disadvantage of considerably limiting the good use of the existing space under a sink. Today, the lower cupboards for console sinks are still provided in many cases with recesses for the toilet siphon housing. This means additional costs for the furniture builder, as well as a reduction of the space in the lower cabinet.

From document JP 7071061 a drain set for sinks is known, in which a toilet drain is arranged relatively close to the lower side of the sink to improve the possibility of using the space below the sink. The toilet siphon is formed by a cup-shaped part, to which an immersion tube appears, which together with a cover-shaped part of the toilet siphon is connected to a drain valve housing. The cover-shaped part of the toilet siphon covers the cup-shaped part and has a splice pipe for a drain pipe. However, no linkage is provided for the operation of the drain valve but a flexible wire, which is guided in a wrapper, which passes through the bottom side of the cup-shaped part, so that one end of the wire is directed inside the immersion tube. This known drain set is not suitable for a console sink robintry with drive linkage for a drain valve body.

In addition, in EP 1 873 317 A1 a relatively flat construction drain set for washbasins is proposed, which has a drain housing that must be disposed directly on the underside of the washbasin and a drain valve, the valve being provided of drainage of a drive pin, which extends downwards to the interior of the housing and at whose lower end attacks an actuating lever that passes in a sealed manner through the housing. The drain housing here has a side outlet opening, in which a horizontal drain channel is molded, oriented towards the rear side of the sink.

Document DE 102 56 844 A1 discloses a drain elbow with a fixing area fixed on the wall or on the roof of a building, as well as with an elbow area provided with a splicing device. The drain elbow is designed in particular for toilet bowls and has a liquid-tight sealing area, partly flexible, which allows a change of rear position of the elbow area with respect to the fixing area. A configuration of the drain elbow provides that the joint area comprises a spherical joint and a telescopic adjustment. The spherical joint is responsible for making changes of position, in which the central axis of the elbow zone forms an angle with respect to the central axis of the fixing area.

Document DE 203 11 666 U1 describes a shower tray element made of rigid foam with a support surface and a central drain, which has a telescopic drain, formed by a telescopic outer part and a telescopic inner part. The telescopic outer part, as well as the telescopic inner part are arranged at least partly above the support surface. In addition, the shower tray element has a recess assigned to the telescopic outer part, which leaves it radially exposed and allows access for mounting from below to the telescopic outer part. The drain part can, moreover, as usual, have a connected drain pipe, the drain pipe being connected by a spherical joint with the telescopic outer part.

The present invention has the objective of making available a drain set of the type indicated at the beginning, which also offers a better possibility of using the existing space under a washbasin, in addition to being able to be mounted simply and quickly.

This objective is achieved by a drain set with the characteristics of claim 1.

The drain set according to the invention is characterized in that the tubing provided with the drain bend is made as a spherical joint pipe, with which the drain bend is articulated, the drain bend presenting a 90 ° angled section with a radius of curvature less than 100 mm with respect to the central axis of the drain elbow and a straight, elongated pipe section, arranged below and because the piece of drain pipe has a second pipe for the alternative guidance of the drive rod towards the valve body

The two pipes, which are provided for guiding a drive rod towards the valve body, are preferably molded substantially diametrically with respect to each other in the piece of drain pipe. This configuration allows the drain elbow to be arranged on the right or left side of the piece of drain pipe. For this, the piece of drain pipe is simply rotated or placed on the bottom side of the sink such that the spherical joint pipe, with which the drain bend is connected in an articulated and liquid-tight manner, is located on the desired side, that is, on the right or on the left, seen from the front side of the console sink in question, in the piece of drain pipe. Thanks to the double embodiment of the tubing that guides the actuation rod, it is guaranteed that the actuating rod attacking in the valve body can be connected in both cases without problems with the actuating rod usually integrated in the water tap provided of a mango The tubing of the piece of drain pipe that does not house any drive rod is provided with a threaded closure.

In the drain set according to the invention, therefore, the space below the piece of drain pipe can be used advantageously to deposit objects or for subsequent assembled parts, such as drawers or the like. The toilet siphon, which is made, for example, in the form of a U-bend, which in conventional drain sets with drive linkage is arranged directly below the piece of drain pipe, can be arranged in the drain set according to the invention near the wall that carries the sink or near a rear wall of a lower cabinet. Thanks to the spherical articulation tubing and the articulated connection of the drain elbow in the piece of drain pipe, a simple and rapid adaptation of the drain set to tolerances is possible with respect to the position of the drain pipe hole on the side of the wall, so that the assembly of the drain set can be carried out correspondingly easily and quickly. The spherical joint allows, in particular, the compensation of an axial offset. Therefore, the drain set according to the invention is characterized by great flexibility in assembly.

A preferable configuration of the drain set according to the invention provides that the length of the spherical joint pipe is less than the height of the piece of drain pipe. In this way an arrangement of the drain set is achieved, which occupies especially little space.

Another preferable configuration of the drain set according to the invention provides that the spherical joint pipe is made in such a way that the drain elbow connected therewith in an articulated and liquid-tight manner can be rotated in a horizontal plane at least 15 °, preferably at minus 18º with respect to the spherical joint pipe. This configuration offers sufficient tolerance compensation with respect to the corresponding position of the drain pipe hole in the wall that carries the sink. The drain set according to the invention can therefore be connected without problems with a drain pipe hole on the wall side, which is arranged, for example, in line with the drive rod that passes through the drain pipe piece. .

Another advantageous configuration of the drain set according to the invention is characterized in that the spherical articulation tubing is realized in such a way that the drain elbow connected therewith in an articulated and liquid-tight manner can be rotated at least 180 ° in a vertical plane. This configuration allows, in particular, a turn of the drain elbow to a position, in which its elongated, straight section is directed vertically downwards. On the other hand, the drain elbow can be guided in this configuration also to a position in which the elongated, straight section extends in the horizontal direction and in the opposite direction to the actuating rod that passes through the piece of drain pipe . The arrangement indicated lastly allows, for example, the possibility of having a handle of the drive linkage or a corresponding drive element on the front side of the sink or in the area in front of the sink. In this case, if necessary, there is better access to the handle or drive element, which would be an advantage, in particular for people with physical disabilities, such as people in wheelchairs.

With respect to an embodiment of the drainage set that takes up little space, it is also advantageous that the spherical articulation tubing is molded according to another preferable configuration of the invention in the piece of drain pipe at the height or in an overlapped height area of the at least one pipe for housing the actuator rod for the valve body.

Preferred and advantageous configurations of the drain set according to the invention are indicated in the dependent claims.

forward with respect to the drive rod.

The drain set shown in the drawing is intended for console sinks (washbasins), in which the operation of the drain valve must be carried out by means of a drive link 1. Usually, a part 1.1 of such a drive linkage It is integrated in a basin feeding robineteria or in a water tap. The console washbasin 2 shown in Figure 3 is provided with a drive element 1.2, which is made separately from a feed robintry (not shown), which can be mounted for example on a wall or on a stone countertop natural that covers a lower closet.

The drain set comprises a drain valve housing 3, which is inserted from above into the drain hole made at the bottom of the washbasin (console washbasin) 2. The drain valve housing 3 has an inlet section 3.1 which it widens conically upwards, which forms a valve seat for a valve body 4 of the drain valve. The valve body 4 has a plate-shaped closure piece, in which a pin 4.1 extending downwards or something similar is fixed. Below the valve seat, the drain valve housing 3 is provided with openings 3.2, through which water can flow to the drain set, which when closed the drain valve flows to the overflow pipe integrated in the console sink.

During assembly of the drain set, the drain valve housing 3 is connected to a piece of drain pipe 5, which is placed directly on the bottom side of the console washbasin. For this purpose, the drain valve housing 3 has a circular cylindrical section with an external thread at its lower end. The piece of drain pipe 5 has a cylindrical section 5.1 with a corresponding internal thread. At the upper end of the cylindrical section 5.1, a flange 5.2 is made, which protrudes radially outward, which serves as a support surface for a seal ring.

In the drain pipe piece 5 a spherical joint pipe 5.3 is molded, which extends substantially at right angles to the vertical central axis M of the cylindrical section 5.1 of the drain pipe piece 5. With the ball joint joint 5.3 is connected a drain elbow 6 in an articulated and liquid-tight manner.

The axial length of the spherical joint pipe 5.3. is less than the height of the drain pipe piece 5. On its side opposite to the spherical articulation pipe 5.3, the drain pipe piece 5 has a section of bent tube wall 5.4 or in the form of a quarter of a ball bowl 5.4 The angled or quarter-shaped configuration of a spherical cuvette of the pipe wall section 5.4 prevents a build-up of dirt particles in the drain pipe piece 5 and contributes to a more uniform, less noisy water flow in the game Drain

To raise or lower the valve body 4 inserted in the drain valve housing 3, a drive rod 1.3 is provided. The drive rod 1.3 is made substantially straight and is guided by a tubing 5.5 molded laterally in the piece of drain pipe 5 towards the bottom side of the pin 4.1 of the valve body 4. The pipe 5.5 extends substantially at right angles with respect to the vertical central axis M of the piece of drain pipe 5 and is provided with an external thread 5.6 to screw a union nut 7 that surrounds it. The drive rod 1.3 is housed in the tubing 5.5 in a rotating and liquid-tight manner.

In addition to the pipe 5.5, the piece of drain pipe 5 has a second pipe 5.7, which can also be used as a passage for the drive rod 1.3. The two pipes 5.5, 5.7 are preferably made in the same way and are molded substantially diametrically with respect to each other in the piece of drain pipe 5. The pipes 5.5, 5.7 allow a bilateral mounting of the drive rod

1.3 in the piece of drain pipe 5.

The tubing 5.5, 5.7 that is not required for guiding the drive rod 1.3 is closed by means of a threaded plug (blind plug) 8 that can be screwed into the external thread 5.6 or 5.8 of the tubing in a liquid tight manner. The screw plug 8 is preferably provided with a gasket inside. 5.5 tubing,

5.7 are molded approximately halfway up the piece of drain pipe 5 into a piece in it. The spherical articulation tubing 5.3 is molded approximately at a height in an area of height of the pipes 5.5, 5.7 in the piece of drain pipe 5. In particular in Figures 1 and 2 it can be seen that the central axis of the pipes 5.5, 5.7 extends above the central axis of the spherical articulation tubing 5.3 which extends in the transverse direction with respect to it, the height distance of this central axis being less than the internal diameter of the corresponding tubing 5.5, 5.7.

The drain elbow 6 is formed by a bent section of 90 ° 6.1 with a radius of curvature of less than 100 mm, preferably less than 90 mm with respect to the central axis of the drain elbow 6 and an elongated, straight pipe section 6.2 continuation. The spherical articulation tubing 5.3 or the spherical articulation 6.3 is liquid tight between the piece of drain pipe 5 and the drain bend 6 is made such that the drain bend 6 is rotatable in a horizontal plane approximately 20 ° with respect to the spherical joint tubing

5.3 (see Figures 5 and 7). The turning range is marked with the double arrow D.

The drain elbow 6 connected by the spherical joint 6.3 rotatably in the piece of drain pipe 5 allows compensation of an axial offset between the drain hole of the console washbasin 2 and a drain pipe hole that is arranged in a wall that carries the console washbasin 2 or a rear wall of a lower cabinet.

In addition, this spherical joint 6.3 is made in such a way that the drain elbow 6 tightly connected to liquids with the spherical joint tubing 5.3 can be rotated at least 180 ° in the vertical plane (see Figure 8).

The drain elbow 6 is removably and fluid tightly connected to the outlet side with another drain elbow 9. The drain elbow 9 also comprises a bent section of 90 ° 9.1 and an elongated, straight pipe section 9.2 then, the radius of curvature of elbow 9.1 being in turn less than 100 mm, preferably less than 90 mm relative to the central axis M9 of the drain elbow 9. Elbow 9.1 is provided at its end with an outer thread, in the that a union nut 10 that wraps the straight section 6.2 of the drain elbow 6 is screwed. The union nut 10 tightens a seal ring that conically narrows between the outer surface of the final section 6.2 straight from the drain elbow 6 and the inner surface of a housing pipe in the elbow section 9.1 of the drain elbow 9 provided below.

The drain elbow 9 is removably connected with the toilet siphon 11. The toilet siphon 11 has a straight pipe section 11.1 and then a 180 ° elbow section 11.2 At the free end of the straight pipe section 11.1, in which The straight section 9.2 of the drain bend 9 has been inserted, an external thread is also made, in which a connecting nut 12 is screwed to tighten the seal ring.

The distance between the central axis M11.1 on the inlet side of the toilet siphon 11 and the central axis M11.2 on the exit side of the 180º angled section 11.2 corresponds to the distance between the central axis M vertical of the pipe piece of drain 5 and of the central longitudinal axis M6 of the straight pipe section 6.2 of the drain bend 6 (see Figure 1).

A drain elbow 13 is in turn connected to the outlet side of the 180 ° 11.2 elongated section. The drain elbow 13 is rotatably connected to the end of the 180 ° elongated section 11.2 by a spherical joint 13.1 liquid-tight.

The drain set according to the invention allows an improved use of space in a lower cabinet. In Figure 2, the rear wall 14 of a lower cabinet is indicated by the two dashed lines and points that extend parallel to each other. Dotted lines 15, 16 mark an upper or later limit of a possible storage space inside the lower cabinet.
