JUNCTION BENCH AND METHOD FOR CONNECTING A DRAIN LINE OF A SANITARY APPLIANCE TO A DRAIN PIPE

Description

[0001] The present invention relates to a offset bend, a method, and a set for connecting a drain line of a sanitary article to a drainpipe. The invention is particularly useful for connecting drain lines and drainpipes (for example, in or in front of a building wall and / or a building floor) that have a horizontal and / or vertical offset.

[0002] Such a pipe offset can occur, for example, during bathroom renovations when a floor-standing toilet is replaced with a wall-hung toilet. Floor-standing toilets can have drain pipes for draining the flushing liquid, which lead vertically into a building floor, for example, and must be reused for wall-hung toilets. Wall-hung toilets are usually attached to a building wall using a mounting frame and have a drain pipe for draining the flushing liquid. The drain pipe can extend at least partially in a vertical direction and run at a closer distance to the building wall than the drain pipe of the original floor-standing toilet. Offset bends are known to bridge the resulting pipe offset between the drain pipe of the wall-hung toilet and the drain pipe of the original floor-standing toilet.When installing the offset bends, their offset must be adjusted to the cable offset. This is done by cutting the offset bends to length and then gluing them together. Such offset bends are known, for example, from DE 20 2008 009 465 U1 and DE 10 2009 048 246 A1.

[0003] If a flexure is deflected too much, it becomes unusable and must be replaced with a new one. Furthermore, curing the adhesive bonds on the flexures is time-consuming.

[0004] From CN 102561502 B, a stepped bend with the features of the preamble of claim 1 is known. This is labor-intensive due to the necessary cutting of the connecting pipe and the complex screwing of the socket joints.

[0005] The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and, in particular, to provide a stepped elbow whose offset can be reversibly adjusted with little expenditure of time. Furthermore, a method is to be provided by which the offset of a stepped elbow can be reversibly adjusted with little expenditure of time. Furthermore, a set is to be provided by which the offset of a pipe bend can be reversibly adjusted with little expenditure of time.

[0006] These objects are achieved with a spring arch and a method according to the features of the independent patent claims. Further advantageous embodiments of the invention are specified in the dependent patent claims. It should be noted that the features listed individually in the patent claims can be combined with one another in the claimed combinations and define further embodiments of the invention. Furthermore, the features listed in the patent claims are further specified and explained in the description, with further preferred embodiments of the invention being presented.

[0007] To this end, a projection bend for connecting a drain line of a sanitary article to a drain pipe having the features of claim 1 contributes.

[0008] The sanitary article, in particular a water-conducting and / or wall-mounted article, can be, for example, a toilet, a shower-WC, toilet bowl, sanitary ceramics, or a bidet. The sanitary article can be attached and / or attachable to a building wall and / or floor, for example, using a mounting frame. The mounting frame can, for example, comprise at least one metal profile and / or a cistern for holding a flushing liquid for flushing the sanitary article. After the mounting frame has been attached to the building wall and / or floor, the mounting frame can, in particular, be covered by a false wall, which comprises, for example, at least one panel and / or at least one cladding element. The at least one panel can, for example, be a plasterboard and / or the at least one cladding element can be a tile. The sanitary article can then be attached to the mounting frame.For this purpose, the mounting frame can have at least one fastening element for the sanitary article, which is designed, for example, in the manner of a metal rod or threaded rod. The mounting frame, in particular, has a plurality of fastening elements for the sanitary article, wherein the fastening elements can be arranged, in particular, at a distance from one another and / or at the same height.

[0009] The sanitary article has a drain line for draining the flushing liquid after a flushing process. The drain line can be tubular and / or designed in the manner of a drain line bend. Furthermore, the drain line can have a bend of, for example, greater than 90°. Furthermore, the drain line can have at least one horizontally extending section and / or at least one vertically extending section. Furthermore, the drain line can be attached to the mounting frame, for example, using a pipe clamp.

[0010] The drainpipe can, for example, extend at least partially through the building wall and / or the building floor. In particular, the drainpipe can have a drainpipe inlet at one longitudinal end, from which the drainpipe extends at least partially (essentially) horizontally or (essentially) vertically through the building wall and / or the building floor. In particular, the drainpipe can at least partially have a gradient of, for example, 1° (degrees) to 10°, preferably 1° to 5°, particularly preferably (essentially) 3°. The flushing liquid can be fed, in particular, to a public sewer system via the drainpipe.

[0011] The offset bend comprises a first pipe bend with an inlet nozzle and a first connecting nozzle. The offset bend or the first pipe bend can be connected to the drain line via the inlet nozzle, in particular (liquid-tight and / or gas-tight). Furthermore, the offset bend or the inlet nozzle can also be attached (in particular directly) to the mounting frame or a pipe clamp of the mounting frame. For this purpose, the offset bend or the inlet nozzle can, for example, have a circumferential collar and / or a circumferential groove. This makes it possible, in particular, to compensate for vertical pipe offsets. In addition, the offset bend or the inlet nozzle can be connected (in particular directly) to a connecting nozzle and / or a toilet connection piece. For this purpose, a seal, in particular an annular or disc-shaped seal, can be arranged in and / or on the inlet nozzle.The seal can, in particular, prevent liquids and / or gases from escaping from a gap between the inlet nozzle and the drain line. Furthermore, the inlet nozzle can extend at least partially along a, in particular straight, longitudinal axis of the inlet nozzle and / or have a round or circular cross-section. Furthermore, an inlet nozzle opening of the inlet nozzle can have a diameter of 32 mm to 315 mm. The first connecting nozzle can extend at least partially along a, in particular straight, first longitudinal axis of the connecting nozzle.

[0012] The offset bend comprises a second pipe bend with a drain nozzle and a second connecting nozzle. The offset bend or the second pipe bend can be connected, in particular (liquid-tight and / or gas-tight), to the drain pipe via the drain nozzle. For this purpose, a seal, in particular an annular seal, can be arranged in and / or on the drain nozzle and / or in and / or on the drain pipe. Furthermore, the drain nozzle can extend at least partially along a drain nozzle longitudinal axis, in particular a straight one, and / or have a round or circular cross-section. Furthermore, a drain nozzle opening of the drain nozzle can have a diameter of, for example, 32 mm (millimeters) to 315 mm. The inlet nozzle longitudinal axis of the inlet nozzle or the inlet nozzle opening runs, in particular, parallel to the drain nozzle longitudinal axis of the drain nozzle or the drain nozzle opening.The second connecting piece can extend at least partially along a, in particular straight, second connecting piece longitudinal axis.

[0013] In addition, the offset bend has at least one bracing device for bracing the first pipe bend to the second pipe bend. The at least one bracing device allows the first pipe bend and the second pipe bend to be braced together in such a way that they cannot (unintentionally and / or independently) detach from one another. Furthermore, the first pipe bend and the second pipe bend can be braced together by the at least one bracing device in such a way that the inlet nozzle and the outlet nozzle are arranged offset from one another. "Bracing" can be understood, for example, as the at least one bracing device generating a force that holds the first pipe bend in or on the second pipe bend. The force can act, in particular, parallel to the first connecting nozzle longitudinal axis and / or the second connecting nozzle longitudinal axis.The at least one clamping device enables, in particular, a reversible and / or non-destructive clamping and unclamping of the first pipe bend and the second pipe bend, in particular as frequently as desired. The at least one clamping device can, for example, be designed in the manner of a latching connection between the first pipe bend and the second pipe bend.

[0014] The offset bend has a connecting pipe which connects the first connecting piece of the first pipe bend to the second connecting piece of the second pipe bend, such that the inlet piece and the outlet piece are arranged with an offset, wherein the connecting pipe is formed according to the invention from a plurality of pipe segments. The connecting pipe connects the first connecting piece of the first pipe bend to the second connecting piece of the second pipe bend in a fluid-conducting manner, such that the inlet piece and the outlet piece are arranged with an (in particular additional and / or adapted) offset. The offset is in particular a distance between the inlet piece longitudinal axis of the inlet piece or the inlet piece opening and the outlet piece longitudinal axis of the outlet piece or the outlet piece opening. The offset can be, for example, 50 mm to 1,200 mm, preferably 60 mm to 210 mm. The connecting pipe orThe pipe segments of the connecting pipe extend in particular along a, in particular straight, longitudinal axis of the connecting pipe. Furthermore, the connecting pipe or the pipe segments of the connecting pipe can be inserted, in particular parallel to the first connecting piece longitudinal axis, into the first connecting piece of the first pipe bend and / or parallel to the second connecting piece longitudinal axis into the second connecting piece of the second pipe bend, in particular in a liquid-tight and / or gas-tight manner. As a result, the connecting pipe longitudinal axis can be aligned with the first connecting piece longitudinal axis and / or the second connecting piece longitudinal axis. The connecting pipe or the pipe segments of the connecting pipe are in particular not glued to the first connecting piece and / or second connecting piece.Instead, a seal may be arranged between the connecting pipe and the first connecting piece and / or between the connecting pipe and the second connecting piece.

[0015] According to the invention, the connecting pipe or the pipe segments of the connecting pipe can be clamped by the at least one clamping device. In particular, the connecting pipe or the pipe segments can be clamped between the first connecting piece of the first pipe bend and the second connecting piece of the second pipe bend by the at least one clamping device. With the aid of a suitable number of pipe segments, the offset of the inlet nozzle longitudinal axis and the outlet nozzle longitudinal axis can be adjusted, increased, and / or reduced. Distances or offset jumps of 10 mm increments are preferably feasible. "Clamping" can also be understood, for example, to mean that the at least one clamping device generates a force that holds the connecting pipe or the pipe segments in or on the first connecting piece and / or the second connecting piece.The force can act in particular parallel to the first connecting piece longitudinal axis, the second connecting piece longitudinal axis and / or the connecting pipe longitudinal axis. The at least one bracing device enables in particular a bracing and relaxing of the connecting pipe or a release of the connecting pipe from the first connecting piece and / or second connecting piece, in particular as frequently as desired, reversibly and / or non-destructively. As a result, in order to adjust the offset, the connecting pipe can be used and / or replaced, in particular multiple times, for example with a connecting pipe of a suitable connecting pipe length. The at least one bracing device can be designed, for example, in the manner of a snap-in connection between the connecting pipe and the first connecting piece and / or between the connecting pipe and the second connecting piece. The bracing device can be provided orbe arranged such that the connecting pipe or the at least one pipe segment can be clamped relative to the first connecting piece and / or second connecting piece, in particular by setting an at least force-locking connection.

[0016] According to the invention, the connecting pipe is formed from a plurality of pipe segments. The connecting pipe can in particular be formed from any number of pipe segments. For example, the connecting pipe can be formed from 2 to 10 pipe segments. Each pipe segment can have a pipe segment length of, for example, 10 mm to 80 mm, in particular parallel to the longitudinal axis of the connecting pipe. The individual pipe segments are in particular inserted into one another and / or not glued to one another. At least one seal can be arranged between the individual pipe segments. In order to adapt the offset between the inlet nozzle and the outlet nozzle of the offset bend to the line offset between the drain line and the drain pipe, the connecting pipe can be assembled from a suitable number of pipe segments so that the connecting pipe has the suitable connecting pipe length.The individual pipe segments can be clamped together, in particular by the at least one clamping device, so that the individual pipe segments cannot become detached from one another. The at least one clamping device enables, in particular, a reversible and / or non-destructive clamping and unclamping of the pipe segments, in particular as frequently as desired. Furthermore, the pipe segments can be connected with at least one screw, clamp, and / or sleeve.

[0017] At least two pipe segments can have different pipe segment lengths. For example, the pipe segments can have a pipe segment length of 10 mm, 20 mm, 40 mm, and / or 80 mm.

[0018] The pipe segments may have a non-circular cross-section. In particular, all pipe segments of the connecting pipe have a non-circular cross-section. Furthermore, the first connecting piece and / or second connecting piece may also have a non-circular cross-section. For example, all pipe segments, the first connecting piece, and / or the second connecting piece may have an oval cross-section. The cross-section extends, in particular, orthogonally to the first connecting piece longitudinal axis, the second connecting piece longitudinal axis, and / or the connecting pipe longitudinal axis.The pipe segments, the first connecting piece and / or the second connecting piece can have a first diameter of, for example, 40 mm to 100 mm, preferably 50 to 70 mm, particularly preferably (essentially) 60 mm, in a first direction, in particular parallel to the inlet nozzle longitudinal axis and / or outlet nozzle longitudinal axis, and / or a second diameter of, for example, 80 mm to 160 mm, preferably 100 mm to 140 mm, particularly preferably (essentially) 120 mm, in a second direction, in particular orthogonal to the inlet nozzle longitudinal axis, outlet nozzle longitudinal axis, first connecting piece longitudinal axis, second connecting piece longitudinal axis, connecting pipe longitudinal axis and / or the first direction. As a result, the first connecting piece, the second connecting piece and / or the connecting pipe can be designed to be particularly flat, so that the offset bend can be arranged in a particularly invisible manner in the building floor.

[0019] According to the invention, the at least one bracing device extends from the first pipe bend to the second pipe bend. In particular, the at least one bracing device can extend from the first connecting piece of the first pipe bend to the second connecting piece of the second pipe bend. The offset bend can in particular have two bracing devices, which can be arranged, for example, on opposite sides of the offset bend.

[0020] The at least one bracing device can comprise at least one rod-shaped element. The at least one rod-shaped element can be made at least partially of plastic and / or metal, such as stainless steel, and / or be designed in the manner of a threaded rod. The at least one rod-shaped element can, for example, have a rod diameter of 4 mm to 10 mm.

[0021] The first pipe bend and / or the second pipe bend can have at least one guide for the at least one bracing device. The first pipe bend and / or the second pipe bend can in particular each have two guides for the at least one bracing device, which can in particular be arranged on opposite sides of the offset bend. The at least one guide can be designed in the manner of a through-bore, slot, groove and / or a sleeve. Furthermore, the at least one guide can be formed integrally with the first pipe bend and / or second pipe bend. The at least one rod-shaped element of the at least one bracing device extends in particular through a first guide of the first pipe bend and a second guide of the second pipe bend.

[0022] The at least one bracing device can be fastened to the at least one guide with at least one nut. For this purpose, the at least one nut can be screwed, in particular, onto the at least one rod-shaped element. In particular, a nut can be screwed onto each longitudinal end of the rod-shaped element. By tightening the at least one nut, the bracing of the connecting tube can be increased, in particular, and / or by loosening the at least one nut, the bracing of the connecting tube can be reduced or eliminated.

[0023] Following a further aspect, a method for connecting a drain line of a sanitary article to a drain pipe according to claim 7 is also proposed.

[0024] The line offset can be determined in step a) in particular by measuring, for example, using a tape measure or folding rule. The adjustment of the offset in step c) can be carried out in particular such that the offset (essentially) corresponds to the line offset. For further details on the method, please refer in full to the description of the offset bend.

The connecting pipe 11 extends along a straight connecting pipe longitudinal axis 48 and is formed from a first pipe segment 13, second pipe segment 14, third pipe segment 15 and fourth pipe segment 49.For this purpose, the pipe segments 13, 14, 15, 49 were inserted into one another and clamped to one another and to the first pipe bend 5 and second pipe bend 8 using a first clamping device 16 and a second clamping device 17. The first clamping device 16 comprises a first rod-shaped element 22, and the second clamping device 17 comprises a second rod-shaped element 23. The rod-shaped elements 22, 23 are each designed like a threaded rod. The first rod-shaped element 22 is inserted through a first guide 24 of the first pipe bend 5 and through a second guide 25 of the second pipe bend 8, such that the first rod-shaped element 22 runs parallel to the connecting pipe longitudinal axis 48. The first rod-shaped element 22 was then secured to the guides 24, 25 using a first nut 26 and a second nut 27.Accordingly, the second rod-shaped element 23 of the second bracing device 17 is inserted through a third guide 50 of the second pipe bend 8 and a fourth guide (not visible here) of the first pipe bend 5, so that the second rod-shaped element 23 runs parallel to the connecting pipe longitudinal axis 48. The second rod-shaped element 23 was then secured to the third guide 50 of the second pipe bend 8 and the fourth guide of the first pipe bend 5 with a third nut 28 and a fourth nut (not visible here). The first guide 24 and the fourth guide (not visible here) of the first pipe bend 5 are formed integrally with the first pipe bend 5 and on opposite sides of the first pipe bend 5. Accordingly, the second guide 25 and the third guide 50 of the second pipe bend 8 are formed integrally with the second pipe bend 8 and on opposite sides of the second pipe bend 8.The connecting pipe longitudinal axis 48 of the connecting pipe 11 extends with a first connecting pipe angle 51 to the inlet nozzle 6 or the inlet nozzle longitudinal axis 46, and with a second connecting pipe angle 52 to the outlet nozzle 9 or the outlet nozzle longitudinal axis 47. The first connecting pipe angle 51 and / or the second connecting pipe angle 52 can be, for example, 90° to 110°, particularly preferably 90° or 97°. Furthermore, the inlet nozzle longitudinal axis 46 and the outlet nozzle longitudinal axis 47 can run parallel to one another. The individual components of the offset bend 1 are part of a set 30.

[0029] The Fig. 4 shows as an example the first pipe segment 13, second pipe segment 14 and fourth pipe segment 49 of the Fig. 3 shown connecting pipe 11. The first pipe segment 13 has a first pipe segment length 18 parallel to the connecting pipe longitudinal axis 48, the second pipe segment 14 has a second pipe segment length 19 and the fourth pipe segment 49 has a third pipe segment length 20.
