Description

TECHNICAL AREA

The present invention relates to a siphon arrangement, in particular for a shower area or a shower tray, according to the preamble of claim 1. In addition, it relates to pre-assembly of the siphon arrangement on an assembly frame.

STATE OF THE ART

Siphon arrangements for shower areas or shower trays are known from the prior art. A shower surface or a shower tray typically includes a drain opening, with a siphon serving as an odor trap being placed below the drain opening. As a rule, the siphon is placed first and then the shower surface or shower tray is arranged above the siphon.

In the case of such siphon arrangements, the positioning of the siphon is typically a challenge because the siphon is connected to a pipe network with its outlet and, on the other hand, has to be in the correct position in relation to the outflow opening. In practice, the installer has often resorted to using a large number of pipe bends, which is disadvantageous for the drainage capacity.

From the DE 20 2014 101 176 U1 , the DE 90 03 326 U1 and the EP 1 181 883 various solutions for adjusting siphon arrangements have become known. The disadvantage, however, is their limited application possibilities in terms of ease of installation.

PRESENTATION OF THE INVENTION

Proceeding from this prior art, the object of the invention is to specify a siphon arrangement which reduces the disadvantages of the prior art. A particularly preferred object is to specify a siphon arrangement which is easier to assemble.

This object is solved by the subject matter of claim 1. Accordingly, a siphon arrangement comprises a siphon element and a holding element. The siphon element comprises a bearing section and a siphon channel which has an inlet and an outlet. The holding element is used to connect the siphon element to an assembly frame. The holding element comprises a receiving section for receiving the bearing section of the siphon element and a fastening section for fastening the holding element to the mounting frame. A central axis extends through the receiving portion. The receiving section and the bearing section are designed in such a way that the siphon element can be aligned pivotably about the central axis with respect to the fixed holding element.

The arrangement permits simple assembly of the siphon element, since the siphon element can be pivoted with respect to the holding element and thus also with respect to the mounting frame, whereby the outlet can be aligned with a sewage pipe and with the outlet opening of a sanitary fitting, such as a shower surface. This eliminates the need to arrange a complex pipeline structure with multiple pipe bends.

In addition, the discharge capacity can also be increased, because the outlet can be connected to the sewage pipe without further or without a large number of pipe bends. As a result, a hydraulic loss in the corresponding line can be reduced.

The retaining element is preferably used to connect the siphon element to an assembly frame for assembly purposes. This means that the holding element holds the siphon element in a fixed position relative to the mounting frame and if the siphon element is then firmly connected to the shower surface, in particular as described below, the connection between the siphon element and the holding element becomes obsolete.

The siphon element can preferably be pivoted through a pivoting angle of at least 180°, in particular of at least 240°, particularly preferably through at least 360°.

The embodiment with the largest pivoting angle has the advantage that the siphon element can be pivoted once about its own axis in relation to the stationary holding element, which provides the greatest possible degree of installation freedom. The This means that the installer has full swivel freedom and the siphon arrangement can be used very flexibly.

The receiving section and the bearing section are preferably designed as a snap-in connection. The siphon element can be very easily connected to the bearing section and, if necessary, separated again if the installation situation makes it necessary. The locking connection is designed in such a way that the siphon element can be pivoted about the central axis relative to the holding element.

Preferably, the receiving section and the bearing section are designed in such a way that the siphon element can be aligned at right angles to the central axis within a predetermined clearance so that it can be moved relative to the stationary holding element. This means that the siphon element can be moved transversely to the central axis. As a result, assembly tolerances can be easily compensated for when aligning a drain opening of a shower surface or a shower tray with the inlet.

Preferably, the receiving section and the bearing section are designed in such a way that the siphon element can be aligned in the direction of the central axis within a predetermined clearance so as to be movable relative to the stationary holding element. As a result, the siphon element can be used on the underside of a shower surface or a shower tray, so that any difference in height can be compensated for.

Particularly preferably, the receiving section and the bearing section are designed in such a way that the siphon element can be aligned in the direction of the central axis and transversely to the central axis within a predetermined play in relation to the stationary holding element.

Starting from a neutral position, the predetermined play is preferably in the range from 0 to 6 millimeters, in particular in the range from 0 to 4 millimeters, particularly preferably in the range from 0 to 2 millimeters. The expression neutral position means the position of the siphon element with respect to the holding element, in which the siphon element lies transversely or in the direction of the central axis without the application of force.

Furthermore, the holding element comprises a ring running essentially completely around the central axis, the ring providing the receiving section or the receiving section being formed on the ring.

An essentially completely circumferential ring is understood to be a ring that extends completely or almost completely around the central axis.

Also arranged on the inside of the ring is a multiplicity of spring shackles which are arranged circumferentially, the spring shackles providing the receiving section with their free ends. This means that the siphon element is held in the ring by the spring shackles. The spring tabs are resilient.

Said spring tabs are preferably distributed evenly over the circumference of the ring, as a result of which the siphon element is held in the ring in a self-centering manner.

The receiving section is particularly preferably provided by a locking lug which is arranged on the free end of each spring clip. The detent engages in the bearing section of the siphon element.

The bearing section on the siphon element is preferably designed as a groove running around the central axis. In this case, the groove preferably completely surrounds the central axis, that is to say without an interruption.

The bearing section is preferably on the outside of the siphon, ie not inside the siphon channel.

In the region of the inlet into the siphon element, the siphon element preferably has a seal running around the inlet. The seal essentially completely surrounds the inlet and is preferably used to seal off the underside of a shower tray or a shower surface.

The siphon element preferably has at least one fastening opening which serve to accommodate a fastener for connecting the siphon element to a shower surface or shower tray. The fastening opening is preferably a threaded opening and the fastening means is preferably a screw.

In the present case, the holding element also has the advantage that the siphon element essentially remains in place if the fastening means should be loosened in the event of maintenance.

The outlet is preferably provided by an outlet pipe which runs at an angle of 91° to 98° to the central axis. In this context, essentially at right angles is to be understood as meaning that the outlet pipe runs at an angle of 90° plus/minus 8° to the central axis. The outlet pipe can therefore have a slight incline.

The bearing section is preferably arranged in the area of the inlet. The bearing section is arranged in such a way that the siphon element is arranged in the installed position, viewed from the holding element, in such a way that the outlet pipe lies below the holding element. This prevents the outlet pipe from coming up against parts of the holding element during the pivoting movement of the siphon element.

Particularly preferably, the holding element lies exclusively above a plane which is oriented at right angles to the central axis and which runs at its height through the highest extension of the outlet pipe.

An arrangement comprises an assembly frame and a siphon arrangement as described above, the assembly frame having a bearing point for supporting the holding element. The holding element is therefore mounted on the mounting frame via the bearing point and at the same time forms a receptacle for the siphon element, which is then connected to the mounting frame via the holding element.

The holding element is preferably held at the bearing point by means of a detachable snap-in connection, with the bearing point preferably being arranged fixedly on the mounting frame. The bearing point is particularly preferably an element that is firmly attached to the assembly frame, which, for example, is integrally present on the mounting frame or is welded to it.

The assembly frame is particularly preferably a frame which comprises at least three, in particular four, corners. The siphon arrangement is preferably arranged in the edge area of the frame and/or centrally between two adjacent corners. The arrangement in the edge area creates space for the installation work for the fitter.

Preferably, the arrangement also includes a shower surface, which can be positioned on the mounting frame via stops in such a way that a drain opening of the shower surface is positioned essentially over the inlet of the siphon element. Preferably, the siphon element with the inlet can be aligned within clearance relative to the outlet opening of the shower element. The expression "shower surface" means a flat shower surface or a shower tray or any other form of shower element on which a user can stand.

• in einem ersten Schritt das Montagegestell auf einem Boden positioniert wird,
• dass in einem nachfolgenden Schritt die Siphonanordnung mit dem Montagegestell verbunden wird,
• dass in einem nachfolgenden Schritt das Siphonelement bezüglich des Halteelementes bzw. des Montagegestells über eine Verschwenkbewegung ausgerichtet wird.

A method for pre-assembling an arrangement as described above is characterized in that

• in a first step, the mounting frame is positioned on a floor,
• that in a subsequent step the siphon arrangement is connected to the assembly frame,
• that in a subsequent step the siphon element is aligned with respect to the holding element or the mounting frame by means of a pivoting movement.

Subsequently, ie after the pre-assembly process, the actual assembly process can then follow, which is characterized in that after the pre-assembly process, the shower surface is placed on the assembly frame in a subsequent step; and that in a subsequent step the siphon element is fitted to the underside of the shower surface.

Further embodiments are specified in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the figure 1 a siphon arrangement 1 according to an embodiment of the present invention is shown.

The siphon arrangement 1 essentially comprises a siphon element 2 and a holding element 6. The siphon arrangement 1 is preferably used in connection with a shower surface 18 or a shower tray as a drain element, with the siphon element 2 being connected to the shower surface 18 on an underside 24 of the shower surface 18. Water can then be discharged from the shower surface 18 to a sewage system via the siphon element 2 .

The siphon element 2 has a bearing section 3 with which the siphon element 2 is connected to the holding element 6 . Next, the siphon element 2 has a Siphon channel 21 with an inlet 4 and an outlet 5. Water flows into the siphon channel 21 via the inlet 4 and then exits via the outlet 5.

The holding element 6 is used to connect the siphon element 2 to an assembly frame 7 for assembly purposes, which is explained in more detail below in connection with the attachment of the siphon element 2 to the shower surface 18 . The holding element 6 comprises a receiving section 8 for receiving the bearing section 3 of the siphon element 2 and a fastening section 9 for fastening the holding element 6 to the mounting frame 7. The connection between the siphon element 2 and the mounting frame 7 is in the Figures 4 to 6 shown in more detail while in the figure 2 the connection between siphon element 2 and holding element 6 is shown in more detail.

In the Figures 1 and 2 it is shown that a central axis M extends through the receiving section 8 . The central axis M is oriented in the vertical in the installed position.

The receiving section 8 of the holding element 6 and the bearing section 3 of the siphon element 2 are designed in such a way that the siphon element 2 can be aligned pivotably about the central axis M with respect to the fixed holding element 6 . This means that the siphon element 2 is arranged so that it can pivot relative to the stationary holding element 6 . Due to this pivotability, the outlet 6 of the siphon element 2 can be aligned before the definitive installation of a shower surface 18 lying above the siphon element 2 . In this case, the outlet 6 is aligned in such a way that a connecting line between the outlet 6 and the sewage system requires as few or no deflections as possible. Due to this simple adjustability, the siphon element can be connected to a sewage network very easily, in particular subject to the lowest possible fluidic loss between the siphon element 2 and the sewage network.

In the embodiment shown, the outlet 5 is provided on the siphon element 2 by an outlet pipe 19 . The outlet pipe 19 runs at an angle of 91° to 98° to the central axis M. The outlet pipe 19 therefore has a slight gradient in the installed position.

In the embodiment shown, the siphon element 2 can be pivoted through a pivoting angle of 360°. This means that the siphon element 2 has total pivoting freedom and this enables a simple connection to the sewage network, which has already been explained above.

In the figure 2 becomes a sectional view of the figure 1 shown. In the embodiment shown, the receiving section 8 and the bearing section 3 are designed as a snap-in connection. This means that the siphon element 2 can be snapped into place on the holding element 6 . In the embodiment shown, the retaining element 6 comprises a ring 10 that runs essentially completely around the central axis M. The spring clip 12 is formed on the ring 10 opposite the free end 13 . The spring tabs 12 protrude from the inside 11 of the ring. In the embodiment shown, a plurality of spring tabs 12 are distributed around the ring 10 at regular intervals. The bearing section 3 on the siphon element 2 is, as in the figure 2 shown, provided by a groove 22 running around the central axis M. The groove 22 also extends completely around the central axis M and is designed without an interruption, ie as a completely circumferential groove. The latching lugs 14 then engage in this groove 22 .

In the figure 3 the holding element 6 is shown on its own. The spring tabs 12 are designed to be slightly resilient, such that the siphon element 2 can be moved in a direction transverse to the central axis M relative to the stationary holding element 6, the spring tabs 12 then being elastically deformed. In other words, this means that the receiving section 8 and the bearing section 2 are designed in such a way that the siphon element 2 can be aligned at right angles to the central axis M within a predetermined play X, Y to move the stationary holding element 6 . The game is in the figure 1 drawn.

Of the figure 2 it can further be seen that the latching lug 14 does not completely fill the groove width of the groove 22 . That is, the siphon element 2 can within the Expansion of the groove width in the direction of the central axis M are movably aligned within a predetermined game Z. The height of the siphon element 2 can also be adjusted relative to the holding element 6 .

Starting from a neutral position, the clearance X, Y, Z is preferably in the range from 0 to 6 mm, in particular in the range from 0 to 4 mm, particularly preferably in the range from 0 to 2 mm.

In the embodiment shown, the fastening section 9 has two snap-in tabs 23 with which the holding element 6 can be fastened to the mounting frame 7 via a snap-in connection. The two latching tabs 23 snap into latching openings 25 on the mounting frame 7 .

In the region of the inlet 4 into the siphon element 2 , the siphon element 2 has a seal 15 running around the inlet 4 . The seal 15 seals it, as in the figure 4 is shown, a gap between the underside 24 of a shower surface 18, so that all water is supplied to the inlet 4 or the siphon channel 21.

Furthermore, the siphon element 2 has at least one fastening opening 16 . In the embodiment shown, three fastening openings 16 are distributed evenly around the circumference of the siphon element 2 . The fastening opening 16 serves to receive a fastening means 17 for connecting the siphon element 2 to the shower surface 18. The fastening opening 16 is preferably a threaded opening and the fastening means 17 is preferably a screw. The screw can be actuated from the top 31 of the shower surface 18 and the siphon element 2 is drawn within the clearance between the groove 22 and the spring clip 12 to the underside 24 of the shower surface 18 . In the process, the seal 15 is also drawn against the underside 24 .

With regard to the outlet pipe 19, the bearing section 3 of the siphon element 2 is arranged in the area of the inlet 4 in such a way that the siphon element 2 is arranged in the installed position, viewed from the holding element 6, in such a way that the outlet pipe always lies below the holding element 6. That is, the outlet pipe 19 is arranged such that this for the movement of the siphon element 2 relative to the holding element 6 is no obstacle. In other words, this means that the holding element 6 lies exclusively above a plane which is oriented at right angles to the central axis M and runs through the highest extension of the outlet pipe 19 at its height. The level is in the figure 6 marked with the reference E.

In the figures 4 and 5 an arrangement is then shown comprising a mounting frame 7 and a siphon arrangement 1 as described above. The mounting frame 7 has a bearing point 20 . The holding element 6 is mounted in this bearing point 20 . The fastening section 9 thereby engages in the bearing point 20 . The holding element 6 is held at the bearing point 20 via a detachable snap-in connection. For this purpose, the retaining element 6 has latching tabs 23 in its fastening section 9 , which are arranged in corresponding latching openings 25 on the bearing point 20 .

The bearing point 20 also has a cutout 32 in the shape of a segment of a circle, which surrounds a partial area of the ring 10 on the outside.

Furthermore, the fastening section 9 has two parallel guide edges 26 which can be pushed into guide grooves 27 on the bearing point 20 .

The mounting frame 7 is designed as a rectangle in the embodiment shown. A foot element 28 is arranged in each corner of the rectangle.

The bearing point 20 is fixed to the mounting frame 7 . The bearing point 20 is preferably an integral component or is welded to the mounting frame 7 as a separate part.

The siphon arrangement 1 or the bearing point 20 are preferably arranged centrally between two adjacent corners. However, the position can also be different and will essentially depend on how the shower surface 18 is designed.

From the sectional view of 6 it is shown that the shower surface 18 has a drainage opening 29 . In the area of the drain opening 29 are Fastening means 17 are arranged, which pull the siphon arrangement 1 against the underside 24.

The shower surface 18 can be positioned relative to the mounting frame 7 in such a way that the drain opening 29 is positioned over the inlet 4 of the siphon element 2 . The mounting frame 7 includes corresponding stops in this regard. The stops bear the reference number 30 in the figures. In the embodiment shown, there are two stops 30 on each side of the mounting frame 7 .
