Description

The The invention relates to a leaflet.

One such a questionnaire is usually used to connect to a a - in particular vertically expiring - process provided toilet bowl to a horizontally offset, vertical drainpipe.

One such horizontal offset arises for example in a renovation a bathroom when an old toilet bowl is replaced by a new one Toilet bowl is replaced. Often the position is correct of the "new" toilet drain with the position of existing drainpipe do not match, so that this distance must be bridged.

To bridge the offset, the discontinuity sheet is usually formed as a double-angled (approximately Z-shaped) tube connecting the toilet drain to the drainpipe. Such a Versprungbogen is known, for example DE 94 07 525 U1 ,

In order to adapt the interlude sheet comparatively easily to different offset or jump lengths, it is sometimes provided to carry out the interleaving sheet in several parts. Such a multipart Versprungbogen is for example off US 5,819,326 A known, wherein a portion of the same is adapted immediately prior to assembly by appropriate trimming to the present installation situation.

from time to time the individual parts of the promissory sheet are present the assembly glued together for sealing purposes. It can do that There is a problem that the splice breaks - for example if load stresses on the Versprungbogen by mounting - whereby the leaflet is no longer sufficiently sealed.

Of the Invention is based on the object, a multi-part Versprungbogen specify that in the course of its installation particularly stable and permanently sealable is.

These The object is achieved by The features of claim 1. Thereafter, a Versprungbogen to Connection of a toilet bowl provided with a vertical drain provided to a horizontally offset, vertical drainage pipe, which two - connectable - angle tubes includes. In this case, each angle tube each one hand vertical connection piece for connection to the vertical outlet or to the drainpipe. On the other hand, each angle tube respectively in each case an angled to its connection piece horizontal section. The two horizontal sections are each freeiendseitig by a glued socket joint connected to each other (in one Pre-assembly state) or connected - (in the assembled state). In this case, the two angular tubes are intended inserted in such a way that the two connecting pieces in show opposite directions to each other. Total results thus a kind of Z-shape for the Versprungbogen. According to the invention at least one of the two horizontal sections in an adhesive area its surface with hollows for receiving adhesive Mistake.

The both angle tubes are in particular substantially rectangular trained, d. H. the horizontal section and the connecting piece each close approximately a right angle. Other than that However, angles can be provided. The term horizontal section is therefore to be understood in the sense that this section in the installed state also run at a certain angle to the horizontal can.

With Sleeve connection is a connection point of the two horizontal sections denotes, in which the first horizontal portion freiendseitig a Sleeve comprises, while the second horizontal section freiendseitig, essentially true to fit, can be inserted in this sleeve.

there is particularly provided that the pluggable horizontal section shortened to a certain length before assembly of the Versprungbogens which corresponds to a certain jump distance. The Jump distance is thereby by the distance of the toilet drain defined to the drainpipe. Subsequently, the pluggable Horizontal section glued in the sleeve.

Of the Adhesive area includes one intended for bonding the socket joint Surface area. Accordingly, the adhesive area includes in particular the radially outer surface area the pluggable horizontal section, the inserted state is absorbed by the sleeve. The adhesive area preferably comprises almost the entire radially outside surface the pluggable horizontal section, as - depending on the jump distance - a in each case provide another area of the horizontal section for gluing is. Alternatively or additionally, it is provided that the Sleeve radially inward - in the gluing area - with corresponding troughs for receiving adhesive is provided.

If the insertable horizontal section is glued in the socket during assembly of the Versprungbogens, so the adhesive penetrates into the troughs. After hardening of the adhesive, bulges or noses are formed on the adhesive side, forming a positive connection in the region of the depressions. Thus, the insertion tube is particularly stable received in the sleeve. Even with possibly occurring when connecting the Versprungbogen loads of the splice is thus the risk that solves the splice and thus becomes leaking, significantly reduced.

Preferably are the hollows as about punctiform indentations educated. Other embodiments, such as essentially elongated (trough-shaped) indentations are conceivable. In this case, such an elongated indentation with respect to the longitudinal direction of the horizontal section basically be aligned at any angle, however, they are preferably oriented obliquely. Also Indentations in the form of tangential circumferential grooves, in particular as closed rings, are conceivable.

Conveniently, the troughs are evenly distributed within the gluing area distributed the surface of the horizontal section.

In In a preferred arrangement, the troughs are within the bonding area in tangentially encircling rows, each uniformly over distributed the circumference of the horizontal section. The circulating rows are uniform in the longitudinal direction of the horizontal section spaced apart. Preference is given to the wells in two adjacent rows each "arranged on space".

In an advantageous embodiment of the invention the Versprungbogen further a radially externally aufzuschrumpfenden shrink tube for sealing the socket connection.

there is intended that the shrink tube after bonding the sleeve connection pushed over this and shrunk. Through the shrink tube is thus a created additional seal, even with a faulty Adhesive bond, the tightness of the Versprungbogens ensured.

The Seal the socket joint using this heat shrink tubing can basically also with a Versprungbogen without hollows be advantageous in the gluing area. The sealing of the socket connection Using the shrink tube is so far as independent Considered invention.

Around the cutting of the einzusteckenden horizontal section to facilitate a desired jump distance is advantageously provided that he in this regard with a scale is provided. In this case, the horizontal section is on shortened to a desired scale length to a desired length.

Prefers if the scale is calibrated to the span of the vault arc, so that the cutting to length - without any conversions - especially simply designed. The jump distance is determined by the distance of the Axes of the two vertical connecting pieces of the composite Given a promissory sheet.

In A further advantageous embodiment is the connecting piece for connection to the toilet drain with a tangential on its outer circumference circumferential groove, in particular for fixing a ring collar, Mistake. As a result, the Versprungbogen toilet side, for example be connected by means of a sealing collar, which in the groove intervenes.

Preferably is the promissory sheet of a polar, bondable plastic, in particular PVC (polyvinyl chloride). Other suitable materials are PBT (polybutylene terephthalate), PET (polyethylene terephthalate) or ABS (acrylonitrile-butadiene-styrene).

Prefers the two horizontal sections are flattened, in particular oval, formed, whereby the Versprungbogen for example, in the limited space below a toilet bowl well mounted is.

following an embodiment of the invention with reference to a Drawing explained in more detail. Show:

1 a promissory sheet in three-dimensional representation,

2 the promissory sheet in a side view,

3 a section III-III off 2 ,

each other corresponding parts and sizes are in all figures always provided with the same reference numerals.

1 shows in a three-dimensional representation of a Versprungbogen 1 for connecting a vertical drain of a toilet bowl to a horizontally offset, vertical drainage pipe. The promissory sheet 1 includes a first angle tube 2 (in the illustration on the left), which is assigned to the toilet bowl. Furthermore, the Versprungbogen includes 1 a second angle tube 3 , which is assigned to the drainpipe (in the illustration on the right). The angle tubes manufactured as separate components 2 . 3 are in a horizontal area 4 of the promissory sheet 1 connected to each other or (in the intended assembly state shown here) connected. The horizontal area 4 serves as intended to bridge the horizontal offset between toilet drain and drain pipe.

The drain pipe side angle tube 3 comprises a cross-sectionally round, intended down-facing drain nozzle 5 to the discharge pipe side connection of the Versprungbogens 1 , To the drain neck 5 closes at its upper end 6 approximately at right angles as a socket pipe 7 designated (intended approximately horizontally aligned) horizontal portion of the angle tube 3 at. The socket pipe 7 has a substantially oval cross section, wherein in the intended installation state, the long side of the oval is oriented horizontally and the short side of the oval vertically.

At his from the drain neck 5 opposite end 8th is the socket tube 7 with a sleeve 9 for receiving the toilet side angle tube 2 Mistake.

The toilet side angle tube 2 comprises a, in turn round in cross-section, intended upwardly facing inlet nozzle 10 , to the connection of the Versprungbogens 1 to the vertical outlet of the toilet bowl. The inlet nozzle 10 is with two spaced, radially protruding projections 11 . 12 provided by a tangential circumferential groove 13 is formed. In this groove 13 For example, an annular sealing sleeve for firmer connection of the Versprungbogens 1 be attached with the vertical drain.

Analogous to the drain pipe side angle tube 3 closes at the inlet nozzle 10 - at its lower end 14 - Again approximately at right angles, or as intended horizontally, a second, as a plug-in tube 15 designated, horizontal section on. The plug-in tube 15 is analogous to the socket tube 7 in cross section flattened oval. At his from the inlet nozzle 10 opposite end 16 is the plug-in tube 15 partly in the sleeve 9 added. This connection is as a socket connection 17 designated.

Thus the Versprungbogen 1 to different jump lengths w ( 2 ) can be adjusted, the plug-in tube 15 before plugging into the sleeve 9 shortened to a length corresponding to the present offset. To facilitate this cutting is in the longitudinal direction of the Einsteckrohres 15 a scale 18 appropriate. The individual scale parts of the scale 18 are in each case with the total interspacing width w of the interleaving arc resulting from this cutting 1 labeled. The scale 18 is thus on the distance w of the vault 1 calibrated.

The cut-to-length plug-in tube 15 is then intended end in the sleeve 9 bonded. To stabilize this adhesive bond is a plurality of wells 19 in the radially outside surface 20 of the plug-in tube 15 brought in. In these hollows 19 can penetrate the adhesive used during assembly, so that after curing of the adhesive in addition to the adhesive connection a positive connection is formed.

In the present embodiment, the troughs are 19 designed as a substantially punctiform indentations. Other embodiments, such as elongated recesses in the longitudinal and / or circumferential direction and / or oblique orientation, are alternatively conceivable as well.

The hollows 19 are - in a depending on the jump distance w optionally provided for bonding adhesive area K - in tangentially circumferential rows each uniformly over the circumference of the plug-in tube 15 distributed. In the longitudinal direction of the Einsteckrohres 15 the rows are also equally spaced so that the surface 20 in the adhesive area K evenly with hollows 19 is provided.

In 2 is the promissory sheet 1 shown in a side view. Here is on the drain neck 5 at its lower end 21 one with several circumferential, radially protruding sealing lips 22 provided rubber seal 23 postponed. Furthermore, the socket connection 17 between the sleeve pipe 7 and the plug-in tube 15 here in addition to the adhesive connection still with an externally shrunk on shrink tubing 24 Mistake. The shrink tube 24 serves to the glued socket joint 17 additionally to protect against escaping liquids, so that even with a faulty splice an additional sealing effect is given.

In 3 is the promissory sheet 1 according to 2 shown cut. Here it can be seen that the shrink tube 24 is dimensioned such that it on the one hand on the sleeve 9 protrudes and thus the Einsteckrohr 15 partially covering, whereby its sealing function is given. On the other hand, he also passes through a through the sleeve 9 formed, radially circumferential step 30 of the socket pipe 7 so that the heat shrink tubing 24 in the longitudinal direction of the Versprungbogens 1 is particularly well-fixed in position.

In 3 It can also be seen that the sleeve 9 through the stage 30 inside the socket tube 7 a stop 31 for an end edge 32 of the plug-in tube 15 forms, so that the jump distance w of the promissory sheet 1 is very precisely adjustable by the cut-to-length spigot 15 until the stop 31 in the sleeve 9 is inserted.
