The European patent EP 1 001 858 / international registration WO 1999/007494 deals with a threaded coupling adapter for garden hoses. A hose connector for a reliable and precise coupling of a garden hose with a connection with internal thread, z. B. for water systems, comprising

• - Provided a first section with an external thread for a screw with the internal thread of the system connection and
• - A second, substantially cylindrical section for hose assembly.

The first portion includes a strong ring externally threaded and fixedly mounted on a cylindrical portion of a thin metal tube and bounded in the axial direction on the cylindrical portion by first and second flanges of the thin metal tube.

The development represents a system break, since from the plant side a connection with internal thread is required; known water installations with taps always have an external thread. The development relies on the advantageous use of the light bulb with Edison socket and version; there can not be otherwise moved, otherwise the electrical contacts of the socket are uninsulated open; Similar conditions are found in electrical plugs and sockets / couplings - the live parts require isolation and inaccessibility.

According to the publications European patent EP 972,155 / American patent US 6,325,425 / international registration WO 1998/041 791 a detachable hose connection system will be presented, especially for water technology. The system consists of a fitting connection - as for a faucet - a universal housing with inlet-side female thread for fitting the fitting, a coupling piece with sealing / O-ring and a valve sealing disc containing. The counterpart - a hose end connector - also consists of the universal housing, a coupling with sealing / O-ring, a tube attachment for the hose receptacle, a pressure ring slipped over the receptacle and hose and a pressure acting on the pressure ring (and thus on the hose) , through the now discharge-side internal thread of the housing guided pressure screw. The universal housing has at its kupplungsseitigem end half snap hook or bayonet closure, so that two universal housing coupling side against each other out, by detent or rotation yield a liquid-tight detachable connection. It can also be coupled liquid-tight two hose end connector.

The pressure screw is applied on the hose side and screwed against the pressure ring in the direction of the coupling piece.

The German disclosure DE 19503 722 / European patent specification EP 726 418 reports a hose coupling with doppelgohlzylinderförmigem hose connection, wherein the inner pipe socket receives the hose and the outer pipe socket is connected at its end facing away from the coupling via a web with radially movable gripping elements with teeth and on its external thread an axially displaceable two-piece screw from screw with internal thread and hose-guiding inner sleeve receives, wherein the inner sleeve has at its end facing the coupling a conical actuating surface which acts on the cam part of the gripping elements, which in turn press the hose against the inner pipe socket.

For the purpose of hose assembly, the hose connection must be disconnected; The screw piece and the inner sleeve must be placed in the correct position over the end of the hose, the hose connection must be made and the two-piece screwed sleeve must be screwed to the pipe socket. The hose connection is constructed in several parts.

The American patent US 5,816,622 provides a kink protection for a hose connection for a water-bearing system. A known hose connector body with coupling and internal thread for connection to fittings has on the opposite side of the coupling an inner pipe socket for hose receptacle with a brass sleeve placed over it for fastening the hose. Furthermore, the coupling housing is extended as an outer pipe extension also on the opposite side of the coupling to the hose in the axial direction and provided with two diametrically opposed openings into which two manually operated latching hooks, which are part of a pulled over the hose, in the axial Direction extended sleeve of elastomeric material and which make the fastening connection between the protective sleeve and coupling housing.

The line kink protection can only be effective if the bending stiffness of the materials of garden hose and kink protection are matched, otherwise only the kinking of the hose from the end of the coupling housing or pipe socket is moved to the end of the kink protection.

Another anti-buckling solution is offered in the application US 5 181 750; here the bending elasticity of the protection by deeply engaging transversal ribs clearly.

US Pat. Nos. 5,316,348, 5,367,925, 2,009,225 and 5,572,912 disclose a tooling aid which is intended to be useful in frequently changing hose connector operations. It is assumed by a known hose connector body with coupling and internal thread for connection to known fittings, such. B. taps of water technology. According to the advantageous innovation, it is proposed to carry out the exterior of the coupling housing as an external hexagon. Furthermore, it is proposed, as it were, to put a pipe wrench over the hose, which has an internal hexagon with a suitable wrench size, which is to be pushed over the wrench size of the coupling housing. The quasi-pipe wrench, which carries the hose in its interior, is widened over its axial length in such a way that its handleability and grip are improved, which is further enhanced by additional longitudinal grooves or ribs.

The always enclosed quasi pipe wrench limits the flexibility of the water hose in the vicinity of the fitting; furthermore, the anyway tightly tightened by sealing / O-rings sealed connections anyway.

European Patent Application EP 384 516 / American patent US 5 072 971 shows a hollow cylindrical plug / coupling element for large diameter hoses, wherein the male member radially distributed on its outer wall over the circumference, has axially extending ribs and the coupling has correspondingly at these locations in the axial direction recesses for rib reception, according to the axial insertion leads a short radial rotary motion to lock the plug and coupling.

An additional mechanical lever locks connector and coupling together; The lever can also be designed for manual operation.

The European patent application EP 340 518 introduces a quick coupling, on the one hand in the supply line provides a connection for a nipple of a water device and on the other hand at the opposite end, first, a pipe socket for hose receiving and further a pipe socket with a gripping element acting on the tube when a screw is moved towards the clutch. In the central flow channel in the flow direction U-shaped Schlauchplatzsicherung - also called water stop - provided.

The Schlauchplatzsicherung is designed for a flow direction; at its pointing in the flow direction end sits the actual valve with sealing / O-ring, the tip is designed as a caries bow.

Such a quick coupling with Schlauchplatzsicherung / water stop is also the subject of the English patent application GB 2 081 409 ,

Also in this application, the Schlauchplatzsicherung is designed in its embodiment for a flow direction.

The American publication US 4,915,351 presents a hose coupling with a valve, which is pronounced as a disk-shaped diaphragm valve. The hose connection has a hollow cylindrical plunger which presses in the assembled / -ged state of the coupling against the disc-shaped, provided with opening slots membrane of the connector, this expands around the plunger and widening their slots to be flow-through openings. In the separated state, the membrane is returned to its closed state and is pressed at the present water pressure against the shoulder of the connecting part and seals.

When the hose connection is disconnected, the hose coupling seals.

The publication DE 44 33 812 presents a hose connection for connecting a - in particular - garden hose to a water device, via a connection nipple via a rotatably mounted plug-in coupling. The hose connection consists of hose fitting, hose connector body and plug-in coupling, the hose connector body between 15 ° and 75 ° angled - preferably 45 ° angled - designed to be and always guaranteed in connection with the rotatably mounted coupling a twist-and kink-free hose.

To connect a hose connection to a hose this is pushed with its end with dissolved clamping sleeve on the pipe socket. By screwing the clamping sleeve onto the thread, the gripping cams are pressed into the hose and this onto the pipe socket; the permissible clamping range is 16 mmD ... 21 mmD, also different hoses according to type, rigidity and strength can be connected.

To connect the plug-in coupling to a nipple this is inserted without actuation of the actuating sleeve in the clutch chamber - one-handed operation, while pressing the O-ring and the projection, the cam portion of the locking cam radially outwardly pivoting. The locking cams fall into the recess behind the projection; the clutch is engaged. An internal pressure, which tries to push the nipple radially outward, is absorbed by a caulking between the projection and the support surface with the interposition of the cam portion. There are no other circumferentially locking forces that affect the ease of twisting with perfect sealing. A Schlauchplatzsicherung is not shown, but can be installed in the region of the flow channel as an actuated by the nipple valve.

According to the Austrian patent AT 397 294 If a hose coupling is a three-piece hose coupling is presented, consisting of a end to be arranged on a hose socket with an outside circumferential groove, a socket receiving the coupling sleeve and an engaging in both sleeves locking member. All parts are hollow cylindrical. The coupling sleeve has, in the cross-sectional plane in which the groove is coupled with a coupled socket, slots for receiving the locking member engaging in the groove of the plug-in socket. The locking member is formed from at least two circular cross-section approximately T-shaped circular arcs, wherein the height measured in the radial direction of the central web of the approximately T-shaped cross-section in the region of the slots is greater than the measured from the groove bottom of the coupling sleeve wall thickness of the same, and the circular arcs are held together by at least one externally applied thereto annular spring member.

The design is complicated by an additional part; In any case, the captivity of the locking member must be ensured.

Such also known as quick couplings hose connector are in the American publications US 4,561,682 and US 4 591 192 to find.

In the German patent DD 22 57 56 a quick coupling with water stop for garden hoses is presented. The valve body inside the clutch stops the flow of water when the terminal is changed. Disassembly of this quick-release coupling in case of faults and replacement of wearing parts is possible without destroying the quick-release coupling thereby.

The pressure spring loaded valve body works like a check valve.

The disclosure DE 34 26 574 / European registration EP 170 042 presents a coupling as a compound of two water-bearing pipes, which presents a thread on its outer side, on its inner side a rotation and axially spaced therefrom a contact surface which widens in the direction of the free end of the coupling frusto-conical. The coupling works with a nipple, which has an anti-twist device, a union nut for connection to the external thread of the coupling and a contact surface.

The nipple has a second cooperating with the nut oblique bearing surface, so that when combined clutch, the distribution of forces is favorably received.

The disclosure DE 31 33 837 shows a connecting device, which is integrally formed on a hose coupling, a hose connection o. Ä., With a ring of pressure elements in the form of resilient cams, which are pressed by a union nut in the direction of a central pipe socket. An existing from dense inner tube and fabric outer tube, collapsible in a pressureless state flat hose is pushed onto the pipe socket and lies in a groove between two annular beads. Between the hose and the rim of pressure elements, a cylindrical elastomeric sleeve is pushed, which forms a kink protection for the hose with its projecting beyond the pipe socket frustoconical portion.

The union nut of the connection device acts on the spring cams of the pressure elements, which find their hold between the outer pipe socket and the groove between the annular beads, in the direction of the main body; Accordingly, the screwing is formed.

In the patent AT 241 212 a releasable threaded coupling is presented with the peculiarity that the hose end in the coupling can not be damaged, which occurs when the hose between two mutually rotatable conical sleeves is jammed, with large frictional forces occur, leading to cracks in the circumferential direction of the hose. The following hose coupling is recommended for the solution. A hollow cylindrical sleeve has on the device side an external thread and a hexagon for handling and in the axial extension hose side an external thread and then a conical taper. About the insertion sleeve an intermediate sleeve is screwed with an axial bore corresponding to the hose outer diameter. In the region of the axial bore, the intermediate sleeve in turn has an external thread, which receives a threaded sleeve with internal thread and in the axial extension of a loose rotatably mounted hollow cylindrical clamping sleeve is guided, whose inner diameter has a the tube to be imported similar profile. If the screw is screwed to the intermediate sleeve, the loosely mounted clamping sleeve with hose on the thickening of the sleeve is carried along in the axial direction and the hose clamped between the inner profile clamping sleeve and outer diameter / conical taper insert sleeve.

For this hose coupling Einsteck-, intermediate, screw and clamping sleeve are necessary, elaborately designed, threaded with precision turned parts.

Among the American publications US Pat. No. 4,757,768 and US Pat. No. 4,757,769 Two design patents are presented, each for a detachable garden hose coupling with external thread as plug and with internal thread as coupling.

All publications presented are only partially or not at all suitable for specific use as a hose fitting with coupling and water stop - in particular not as a hose fitting with coupling and water stop for water technology in a domestic environment or applications in the small business or trade.

The invention is therefore based on the object, a device according to the preamble of claim 1 a hose fitting with coupling and water stop - to create a hose fitting with coupling and water stop for water technology in a domestic environment or applications in the small business or industry.

This object is achieved by the characterizing features of claim 1; to advantageous embodiments, the dependent claims.

• A) bei der Schlauchverschraubung eine neue Schlauchaufnahme und Klemmvorrichtung verbunden mit Unverlierbarkeit/Lagegerechtigkeit der Druckschraube/-mutter
• B) bei der Schnellkupplung eine neue Rast- und Haltetechnik für den aufzunehmenden Stecker
• C) bei dem Wasserstopp eine neue dem Durchfluß bzw. den Strömungsverhältnissen angepaßte Formgebung – wie Profilierung – des Körpers

zur Anwendung kommen.The aim is to improve the hose fitting with coupling and water stop such that

• A) in the hose fitting a new hose receiving and clamping device connected to captive / Lagegerechtigkeit the pressure screw / nut
• B) in the quick coupling a new locking and holding technology for the male connector
• C) at the water stop a new the flow or the flow conditions adapted shaping - such as profiling - of the body

come into use.

The hose fitting consists essentially of a one-piece connection of hose receiving and coupling; The hose fitting is intended to produce the connection of a hose made of elastomeric material with a coupling piece in the form of a releasable coupling. The hose fitting is commercially available as a plastic part or as a metal part - preferably brass - with plastic inserts or as a metallized plastic part available.

To A) The embodiment of the inventive novelty provides to make the hose receptacle with hose connection so that the disadvantages are improved according to the prior art; For this purpose, it is proposed to make the hose receptacle with the hose connection in principle different. A major disadvantage of all known fittings of this type is certainly that - after the hose was plugged - a clamping device via a pressure screw / nut is usually operated by turning, which then acts firmly holding on the hose on the clamping device. For this purpose, it is necessary to separate the hose receptacle, clamping device and / or pressure screw / nut in order to attach the hose. Often also clamping device and / or pressure screw / nut must be slipped over the hose correctly before plugging. In this case, parts are lost and / or are lined up in the wrong order and / or not in the correct position.

Therefore, it is proposed according to an expression of novelty, hose fitting, clamping device and pressure screw / nut integrally designed to be unique and unmistakable. For this purpose, the hose connection has a base body, on the one hand in a hose receiving hollow cylindrical, slightly merging in the axial direction towards the coupling tube approach and on the other hand via a more external, parallel arranged hollow cylindrical pipe socket via a web a cam member with a radially pointing to the hose Gripping gearing - the clamping device - has, which is widened in the delivery state radially outward and is limited by the inner cylinder of the hollow cylindrical pressure screw / nut. On the coupling side facing the pressure screw / nut has an internal thread, according to diameter and pitch matching the external thread of the body at this point. By moving the pressure screw / nut in the axial direction facing away from the clutch, the clamping device web / cam part / gripping toothing suspended in a similar manner to a film hinge is fed radially in the direction of the hose and radially opened by counter-movement; from the longitudinal process of the pressure screw / nut is a transversal closing / opening of the clamping device, wherein by selecting the thread type - right or left hand thread - the conversion takes place rotational in longitudinal movement and the thread pitch of the longitudinal stroke per revolution or the number of revolutions is set for the closing / opening operation, which means that if a large thread pitch is selected, only a small angle of rotation is required for opening or closing and vice versa.

• – bei dünnwandigen Schläuchen zwei Zacken der Verzahnung ein Labyrinth bilden
• – bei dickwandigen Schläuchen die Zacken bei weniger Umdrehungen greifen.

Depending on the application, the hose receptacle builds extremely short, the number of parts is minimized and handling is absolutely safe and problem-free. The hose adapter is also suitable for the use of pipes. When using smooth tubes or hoses with outer fabrics, the use of a hollow cylindrical elastomeric sealing sleeve between clamping device and line is possible in order to increase the withdrawal forces or the production of a seal. Both thin-walled and thick-walled hoses can be firmly held by the clamping device; the pressure screw / nut so presses on the bead of the rear side of the gripping teeth, that

• - For thin-walled hoses, two teeth of the toothing form a labyrinth
• - In case of thick-walled hoses, the serrations engage with less turns.

To B) A further advantageous embodiment of the invention relates to the region of the coupling - in particular the receiving and securing the Coupling in the coupling. The coupling consists of a substantially hollow cylindrical body whose interior is designed so that it is also substantially hollow cylindrical, provided with a sealing / O-ring coupling piece - such. B. a tap piece, a Einstecknippel, a nipple, a double or multiple clutch, a Reduzierkupplung or a device coupling - receives and seals. The coupling is integrally connected to the hose receptacle.

The constructed according to the prior art couplings consist of a hollow cylindrical body - which is also the main body of the hose receiving - a blown over the body, also hollow cylindrical, slidable in the axial direction actuating sleeve which is biased by a spring, and at least three plastic locking cams , which are also resiliently biased against the inner wall of the actuating sleeve. The coupling piece can be coupled in the sense of a one-handed operation without moving the actuating sleeve; However, there is a risk of crushing when moving the actuating sleeve against a stop of the body in the one-handed operation. To decouple the actuating sleeve is displaced axially against the spring force in the direction of the hose receiving, whereby a support surface between locking cam and actuating sleeve is released and the cam member of the radially outwardly displaced locking cam releases the coupling piece for removal. A disadvantage for the release of the coupling piece has an effect if the hollow cylindrical, open space between the base body and actuating sleeve by soil, sand o. Ä. Polluted, whereby a radial change in position of the locking cam is not possible.

In the case of the metal version, instead of the plastic locking cams, small spring-loaded steel rounded steel pins are to be found whose position likewise changes in the radial direction when the actuating sleeve is displaced. The metal actuating sleeve is guided by means of a slot through an externally accessible grub screw. The limited functionality in case of contamination is also present here. In addition, due to the Voltaschen voltage series, no two differently metallic, electrically conductive materials should be used.

Waiving the above-mentioned disadvantages is recommended to secure the coupling in the coupling as a further advantageous embodiment, an oval-shaped plastic retaining ring special expression. The circlip is positioned in an annular gap between a Kupplungsvorder- or -einführungsteil and a coupling back - limited by the underlying hose receptacle - positionally movable; its two diametrically opposed push buttons, which are attached to the largest extent of the oval ring, are each movably fitted in the recesses of the coupling surface. The oval retaining ring - molding - has in the region of its smallest extension diametrically opposite each a V-shaped or wedge-shaped cross-sectional shape, wherein the tip of the wedge points in the direction of the front / introduction part. In this area, the V / wedge-shaped cross-section through undercut consists essentially of the legs of the wedge, to achieve an additional spring action here as well.

• a) Im Ruhe-Zustand liegt der Sicherungsring oval entspannt in dem Ringspalt zwischen dem Kupplungsvorder- oder -einführungsteil und dem Kupplungsrückteil; die Drucktasten ragen über die Griffmulden der Kupplung hinaus
• b) Wird das Kupplungsstück eingeschoben, erfolgt eine erste Berührung des Kupplungsstücks mit den Spitzen der V-/keilförmigen Querschnitte des Sicherungsrings, die inneren Schenkel des V-/keilförmigen Sicherungsrings federn zurück, der Sicherungsring wird zunächst auf zwei Seiten radial nach außen gedrückt, der ovale Sicherungsring formt sich federnd zu einem Kreisrund
• c) Ist das Kupplungsstück in Gänze eingeschoben, fällt der V-/keilförmige Querschnitt des Sicherungsrings auf Grund seiner Vorspannung in eine Vertiefung hinter einem Vorsprung des Kupplungsstücks ein, wobei sich beide Schenkel des V-/keilförmigen Querschnitts auf beiden Seiten des Rings rastend in die Vertiefung legen, der Sicherungsring nimmt wieder eine ovale Form an
• d) Durch beidseitiges Drücken der aus den Kupplungs-Griffmulden herausragenden Drucktasten des Sicherungsrings wird der ovale Ring zu einem runden, der V-/keilförmige Querschnitt des Rings bewegt sich je beidseitig aus der Vertiefung des Kupplungsstücks radial nach außen, das Kupplungsstück wird so entriegelt und kann aus der Kupplung gezogen werden.

Due to this characteristic of the locking ring, the following operating states result for the coupling piece / coupling plug-in action.

• a) In the rest state of the circlip is oval relaxed in the annular gap between the Kupplungsvorder- or -einführungsteil and the coupling back; the push buttons protrude beyond the grip recesses of the clutch
• b) If the coupling piece is inserted, a first contact of the coupling piece with the tips of the V / wedge-shaped cross sections of the locking ring, the inner legs of the V / wedge-shaped locking ring springs back, the retaining ring is first pressed on two sides radially outward, the oval circlip forms resilient to a circle
• c) If the coupling piece is fully inserted, the V / wedge-shaped cross section of the locking ring falls due to its bias in a recess behind a projection of the coupling piece, both legs of the V / wedge-shaped cross-section on both sides of the ring latching in the Place the recess, the retaining ring again assumes an oval shape
• d) By pressing on both sides of protruding from the clutch recesses pushbuttons of the circlip, the oval ring to a round, the V / wedge-shaped cross section of the ring moves on both sides of the recess of the coupling radially outward, the coupling is unlocked and can be pulled out of the coupling.

Manufacturing is either

• - The coupling - as shown above - constructed in two parts and the two coupling parts are glued together after insertion of the oval locking ring, welded or verprellt or
• - The coupling is constructed in one piece, contains an annular gap for receiving the oval locking ring, which is perhaps designed in two or more pieces and one of the two push buttons is retrofitted after inserting the ring into the coupling housing.

To C) The further advantageous embodiment of the invention is devoted to the consideration of the water stop the interior of the hose fitting. The water stop - also referred to as aquastop - is not to be confused in this application and not to equate with a Schlauchplatzsicherung where hoses are permanently connected to a fixed water installation - as typically in dishwashers and washing machines - where a strong pressure drop below a (adjustable) Threshold, such as. B. when bursting or tearing a supply hose from the tap, is detected; However, smaller hose defects, from which - often even over a longer period - water leaking, not. However, such systems equipped with electronics, microprocessor and sensor technology are now also available on the market.

The here presented water stop is also not a spring-loaded check valve, which should allow a flow or flow only in one direction, d. H. the pressure of a desired flow must overcome the spring force set against a closure flap with sealing / O-ring, and the flow is given with the flap open. If the pressure falls below that of the spring force, it presses the closure flap tightly against a stop with a sealing / O-ring. The pressure of an incipient rearward flow would add to the spring pressure on the closure flap and prevent this backflow.

The presented here water stop is like a 'boat' loose in the flow channel of the hose fitting, has a sealing / O-ring enabled sealing function and forms one of the hollow cylindrical, provided with a sealing / O-ring coupling piece - such. As a tap piece, a Einstecknippel, a nipple, a double or multiple clutch, a Reduzierkupplung or a device coupling - actuated valve to prevent unimpeded water leakage when removing the coupling piece.

The current market offers quick coupling packages consisting of a coupling, a hose connection without water stop and a hose connection with water stop (without manual). This presupposes the knowledge of the user that a hose connection to be created has to be made in the order of water tap - coupling piece - hose fitting without water stop - screwed hose connection with water stop; only then the water stop unfolds its effect depending on the plugged or unplugged coupling piece at the end of the hose connection. If the hose connection created in this way is disconnected from the tap fitting and connected end-reversed, the water stop will have no effect whatsoever. In this respect, the offer package is to be classified as disadvantageous.

According to another offer of a quick coupling package with brass or brass imitations of hose fittings - consisting of a coupling piece, a hose fitting without water stop and a hose connection with water stop (without manual) - flows through the hose connection at the 'wrong' connection of the hose fitting with water stop no water at all to the coupling / tap piece; through the 'wrong' connection, the water stop completely blocks the water supply to the hose. For the user, the condition is initially not explainable; the offer package is to be classified as disadvantageous.

A user-friendly solution would be to offer only hose fittings with water stop, so that neither the assembly nor in the subsequent application consideration must be taken of the hose connection with respect to the water stop. This is with the hose fittings after EP 340 518 or DE 80 32 468 not possible. In both cases, the water stop shows a flow profile only in one direction; in both cases, the hose fitting is only suitable for use on the hose end facing away from the faucet. Depending on the direction of water flow away from the side of the water stop is absolutely 'dull' and rather designed flow inhibiting or preventing, so that excludes a mounting or use of the water supply side hose end.

In another application, the water stop is also designed for operation in a flow direction (it is also supplied only a hose fitting with water stop in the package), but here with proper installation of the water stop on the side facing away from the faucet of the hose end (during assembly on the water stop at the faucet-facing side of the hose end ignites no effect at all) the water stop fluidly 'dull', flow-inhibiting and / or -verhindernd trained, which also - depending on the application and water pressure - from knowledge of the valve technology contributes to significant noise. In this water stop the flow profile is on the side facing away from the flow.

Excluding these significant disadvantages, it is proposed in a further advantageous embodiment of the invention to profile both sides of the water stop fluidly and always deliver the hose fittings with water stop

• - incorrect assembly of the hose fitting with / without water stop is excluded
• - The hose connections have the same ends with water stop
