Description

DESCRIPTION

siphon arrangement

technical field

The present invention relates to a siphon arrangement, in particular for a shower surface or a shower tray, according to the preamble of claim 1. Furthermore, it relates to a pre-assembly of the siphon arrangement in a mounting frame.

State of the art

Trap arrangements for shower surfaces or trays are known from the prior art. Typically, a shower surface or shower tray comprises a drain opening, whereby a siphon serving as an odor trap is placed below the drain opening. As a general rule, the siphon is placed first, and then the shower surface or shower tray is placed above the siphon.

With this type of trap arrangements, positioning of the trap is often a challenge because the trap is connected with its outlet to a pipe network and on the other hand it must be in the correct position relative to the drain opening. In practice, the installer often ends up using a large number of elbows in the pipes, which is unfavorable to drainage performance.

In DE 202014 101 176 U1, DE 90 03 326 U1 and EP 1181 883 various solutions for adjusting siphon arrangements have been disclosed. However, its limited application possibilities are a disadvantage in terms of ease of assembly.

Description of the invention

Starting from this state of the art, the invention is based on the task of providing a siphon arrangement which reduces the disadvantages of the state of the art. A particularly preferred task is to provide a siphon arrangement that is easier to assemble.

This task is solved by the object of claim 1. Accordingly, a siphon assembly comprises a siphon element and a retention element. The siphon element comprises a support section as well as a siphon channel having an inlet and an outlet. The retaining element is used to connect the siphon element to a mounting frame. The retaining element comprises a receiving section for receiving the roller section of the siphon element and a fixing section for fastening the retaining element to the mounting frame. A central shaft extends through the receiving section. The receiving section and the support section are designed in such a way that the siphon element can be aligned with the fixed retaining element so that it can pivot about the central axis.

The arrangement allows easy mounting of the siphon element, since the siphon element can rotate relative to the clamping element and thus also relative to the mounting frame, whereby the outlet can be aligned with a pipe. sewage, as well as with the outlet opening of a sanitary fixture, such as a shower surface. This eliminates the need to organize a complex piping structure with multiple bends.

Furthermore, the discharge capacity can also be increased because the outlet can be connected to the sewage pipe without further or a large number of bends in the pipe. This can reduce hydraulic losses in the corresponding pipe.

Preferably, the retaining member serves to connect the siphon member to a mounting frame for mounting purposes. That is, the retaining element holds the trap element in a fixed position with respect to the mounting frame and when the trap element is firmly connected to the shower surface, in particular as described below, the connection between the siphon element and retention element becomes obsolete.

Preferably, the siphon element is rotatable through an angle of rotation of at least 180°, in particular at least 240°, more preferably at least 360°.

The design with the largest turning angle has the advantage that the siphon element can rotate once about its own axis relative to the fixed retaining element, which provides the greatest possible degree of installation freedom. In other words, the installer has full freedom of rotation and the siphon arrangement can be used with great flexibility.

Preferably, the receiving section and the support section are designed as a snap connection. In this way, the siphon element can be very easily connected to the support section and, if necessary, separated again if the installation situation makes it necessary. The snap connection is designed in such a way that the siphon element can rotate about the central axis relative to the retaining element.

Preferably, the receiving section and the supporting section are designed in such a way that the siphon element can be movably aligned with the fixed retaining element at right angles to the central axis within a predetermined clearance. In other words, the siphon element is movable transversely to the central axis. This makes it easy to compensate for mounting tolerances when aligning the drain opening of a shower tray or shower surface with the inlet.

Preferably, the receiving section and the supporting section are designed in such a way that the siphon element can be aligned with the fixed retaining element in the direction of the central axis within a predetermined clearance. In this way, the siphon element can be brought closer to the bottom of a shower tray or shower surface to compensate for any difference in height.

Particularly preferably, the receiving section and the support section are designed in such a way that the siphon element can be movably aligned in the direction of the center axis and transversely to the center axis within a predetermined clearance with respect to the receiving element. fixed retention.

Starting from a neutral position, the predetermined clearance is preferably in the range of 0 to 6 millimeters, particularly in the range of 0 to 4 millimeters, more preferably in the range of 0 to 2 millimeters. The expression "neutral position" is understood as the position of the siphon element relative to the retaining element in which the siphon element lies transversely or in the direction of the central axis without the application of a force.

Furthermore, the retaining member comprises a substantially entirely circumferential ring about the central axis, wherein the ring provides the receiving portion or the ring has the receiving section formed therein. By substantially circumferential ring is meant a ring that extends completely or almost completely about the central axis.

Also, inside the ring, a plurality of spring plates are circumferentially arranged, whereby the spring plates provide the receiving section with their free ends. This means that the siphon element is held in the ring by the spring plates. Spring plates are designed to be elastic.

Preferably, said spring tabs are evenly distributed around the circumference of the ring, whereby the siphon element remains self-centered in the ring.

In a particularly preferred manner, the receiving section is provided with a latching tab arranged at the free end of each spring plate. The latching tab fits into the support section of the siphon element.

Preferably, the support section in the siphon element is formed as a slot running around the central axis. The groove preferably surrounds the central axis completely, ie without interruption.

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

Preferably, the siphon element has a seal that surrounds the inlet in the inlet area in the siphon element. In this case, the gasket substantially completely surrounds the inlet and preferably serves to seal against the underside of a shower tray or shower surface.

Preferably, the siphon element has at least one fixing opening serving to receive a fixing means for connecting the siphon element to a shower surface or tray. The fixing opening is preferably a threaded opening and the fixing means is preferably a screw.

In the present case, the retaining element has the additional advantage that the siphon element remains substantially in place if the fixing means loosen during maintenance.

Preferably, the outlet is provided with an outlet tube which extends at an angle of 91° to 98° with respect to the central axis. In this context, it is to be understood that the outlet pipe is substantially perpendicular and forms an angle of 90° plus/minus 8° with respect to the central axis. Therefore, the outlet tube may have a slight incline.

Preferably, the support section is arranged in the region of the entrance. The support section is arranged in such a way that the siphon element, seen from the retaining element, is arranged in such a way that the outlet pipe is below the retaining element. This prevents the outlet tube from coming into contact with parts of the retaining member during pivotal movement of the siphon member.

In a particularly preferred way, the retaining element is located exclusively on a plane oriented at right angles to the central axis and passing in its height through the highest extension of the outlet tube.

An arrangement comprises a mounting frame as well as a siphon arrangement as described above, in which the mounting frame has a support point to support the retention element. The retaining element is thus mounted to the mounting frame via the support point and at the same time forms a receptacle for the siphon element, which is connected to the mounting frame via the retaining element. Preferably, the retaining element is held in the fulcrum via a releasable snap connection, whereby the fulcrum is preferably firmly arranged in the mounting frame. Especially preferably, the support point is an element fixed to the mounting frame, which is, for example, provided integrally with the mounting frame or is welded to it.

In a particularly preferred manner, the mounting frame is a frame comprising at least three, in particular four, corners. The siphon arrangement is preferably arranged in the area of the edge of the frame and/or in the center between two adjacent corners. The arrangement in the edge area creates space for the installer for mounting work.

Preferably, the arrangement further comprises a shower surface which is positionable in the mounting frame via stops in such a way that a drain opening of the shower surface is positioned substantially above the inlet of the siphon element. Preferably, the siphon element may be aligned with the inlet within the free space relative to the drain opening of the shower element. By "shower surface" is meant a flat shower surface or a shower tray or any other form of shower element on which a user can stand.

A method for pre-assembling an arrangement according to the above description is characterized in that

In a first step, the mounting frame is placed on the ground,

in a later step, the siphon arrangement is connected to the mounting frame,

in a subsequent step, the siphon element is aligned with respect to the retaining element or the mounting frame by means of a turning movement.

Then, ie after the pre-assembly procedure, you can follow the actual assembly procedure, which is characterized in that, after the pre-assembly procedure, in a subsequent step, the shower surface is placed in the mounting frame; and in that, in a later step, the siphon element is mounted towards the bottom of the shower surface.

Other embodiments are indicated in the dependent claims.

Description of the preferred embodiments

In Fig. 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 retention element 6. The trap arrangement 1 is preferably used in connection with a shower surface 18 or a shower tray as a drainage element, the trap element 2 being connected to the shower surface 18 at a lower part 24 thereof. The water can then be drained from the shower surface 18 into a sewage network through the siphon element 2 .

The siphon element 2 has a support section 3 with which the siphon element 2 is connected to the retaining element 6. Furthermore, the siphon element 2 has a siphon channel 21 with an inlet 4 and an outlet 5. The water flows into the siphon channel 21 through the inlet 4 and then leaves it through the outlet 5.

The retaining element 6 serves to connect the siphon element 2 to a mounting frame 7 for mounting purposes, which will be explained in more detail below in connection with the fixing of the siphon element 2 to the shower surface 18. The retaining element 6 comprises a receiving section 8 for receiving the support section 3 of the siphon element 2 and a fixing section 9 for fixing the retaining element 6 to the mounting frame 7 . The connection between the siphon element 2 and the mounting frame 7 is shown in more detail in Figs. 4 to 6, while, in Fig. 2, the connection between the siphon element 2 and the mounting frame 7 is shown in more detail. the retention element 6. In Figs. 1 and 2, a central axis M is shown to extend through the receiving section 8. The central axis M is oriented vertically in the mounting position.

The receiving section 8 of the retaining element 6 and the supporting section 3 of the siphon element 2 are designed in such a way that the siphon element 2 can rotate about the central axis M relative to the fixed retaining element 6. This means that the siphon element 2 can pivot with respect to the fixed retaining element 6. This rotation allows the outlet 6 of the siphon element 2 to be aligned before the final assembly of a shower surface 18 located above the siphon element 2 . By doing so, outlet 6 is aligned in such a way that a connecting pipe between outlet 6 and the sewage network needs as few diversions as possible. Due to this simple alignment, the siphon element can be connected to a sewage network very easily, in particular with the least possible flow loss between the siphon element 2 and the sewage network.

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

In the embodiment shown, the siphon element 2 can rotate through a rotation angle of 360°. In this way, the siphon element 2 has complete freedom of rotation, which allows a simple connection to the sewage network, which has already been explained above.

In Fig. 2, a sectional view of Fig. 1 is shown. In the embodiment shown, the receiving section 8 and the supporting section 3 are designed as a snap connection. This means that the siphon element 2 can be engaged in the retaining element 6. In the embodiment shown, the retaining element 6 comprises a ring 10 which rotates substantially about the central axis M. In the embodiment shown, the receiving section 8 is provided with a latching tab 14 which is arranged at one end 13 free of a spring plate 12. The spring plate 12 is formed on the ring 10 opposite the free end 13. In this way, the spring tabs 12 protrude from the inner face 11 of the ring. In the embodiment shown, a number of spring tabs 12 are arranged at evenly spaced intervals around the ring 10. The support section 3 of the siphon element 2 is provided, as shown in Fig. 2, with a slot 22 running around from the central axis M. The slot 22 also extends from the inside of the ring. The slot 22 also extends completely around the central axis M and is formed without interruption, ie as a completely circumferential slot. The latching tabs 14 then fit into this slot 22.

In Fig. 3, the retaining element 6 is shown in an autonomous position. The spring tongues 12 are slightly elastic, so that the siphon element 2 can be displaced in the direction transverse to the central axis M with respect to the fixed retaining element 6, whereby the spring tongues 12 are elastically deformed. In other words, this means that the receiving section 8 and the supporting section 2 are formed in such a way that the siphon element 2 can movably align with the fixed retaining element 6 at right angles to the central axis M inside. of a predetermined clearance X, Y. The clearance is shown in Fig. 1.

From Fig. 2, it is further apparent that the latching tab 14 does not completely fill the width of the slot 22. That is, the siphon element 2 can be movably aligned within the extent of the width of the slot in the direction of the central axis M within a predetermined clearance Z. Therefore, the siphon element 2 can also be adjusted in height with respect to the retaining element 6.

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

In the embodiment shown, the fixing section 9 has two hooking tabs 23 with which the retaining element 6 can be fixed to the mounting frame 7 by means of a hooking connection. The two latching tabs 23 fit into the latching openings 25 of the mounting frame 7 .

In the region of the inlet 4 in the siphon element 2, the siphon element 2 has a gasket 15 surrounding the inlet 4. As shown in Fig. 4, the gasket 15 seals a gap between the bottom 24 of a shower surface 18 so that all the water reaches the inlet 4 or siphon channel 21 .

Furthermore, the siphon element 2 has at least one fixing opening 16 . In the shown embodiment, three fixing openings 16 are evenly distributed around the circumference of the siphon element 2. The fixing opening 16 serves to receive a fixing means 17 for connecting the siphon element 2 to the shower surface 18 . The fixing opening 16 is preferably a threaded opening and the fixing means 17 is preferably a thyme. The screw can be actuated from the upper side 31 of the shower surface 18 and in this way the siphon element 2 is drawn towards the lower part 24 of the shower surface 18 within the clearance between the groove 22 and the spring plate 12. This also pulls the gasket 15 towards the bottom 24.

With respect to the outlet pipe 19, the support 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, seen from the retaining element 6 in the mounting position , is arranged in such a way that the outlet tube is always below the retention element 6. That is, the outlet pipe 19 is arranged in such a way that it does not constitute an obstacle to the movement of the siphon element 2 with respect to the retaining element 6. In other words, this means that the retaining element 6 lies exclusively above a plane oriented at right angles to the central axis M and that its height passes through the highest extension of the outlet tube 19. The plane is marked with the reference E in Fig. 6.

In Figs. 4 and 5, an arrangement is shown comprising a mounting frame 7 and a siphon arrangement 1 as described above. The mounting frame 7 has a support point 20 . The retaining element 6 is mounted on this support point 20. In this case, the fixing section 9 engages with the support point 20. The retaining element 6 is held at the fulcrum 20 by a removable snap connection. For this, the retaining element 6 has hooking tabs 23 on its fixing section 9, which are arranged in the corresponding hooking openings 25 on the support point 20 .

The support point 20 also has a segment-shaped circular cutout 32 that surrounds a partial area of the ring 10 on the outside.

Furthermore, the fixing section 9 has two parallel guide edges 26 which can be inserted into the guide grooves 27 at the support point 20.

In the embodiment shown, the mounting frame 7 is formed as a rectangle. In this case, at each corner of the rectangle, a foot element 28 is provided.

The support point 20 is fixedly arranged on the mounting frame 7 . Preferably, the support point 20 is an integral part or is welded as a separate part to the mounting frame 7 .

The siphon arrangement 1 or the support point 20 is preferably arranged in the center 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 in Fig. 6, it can be seen that the shower surface 18 has a drainage opening 29 . In the area of the drainage opening 29, the fixing means 17 are arranged, which pull the siphon arrangement 1 against the lower part 24 .

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