Definitions
- the invention relates to an adapter coupling for connecting a hose or the like to a tap, which is equipped with a sleeve, which is used to establish the connection to the tap and has a connection for the hose.
- taps are often equipped with an attachment piece which has a standardized thread which can be screwed onto the likewise standardized thread of the water-emitting end of the water outlet of taps.
- a sleeve connected to the hose can be pushed onto this end piece, which is a kind of spigot end, to produce a pressure-tight connection.
- Such couplings consisting of the end piece and the sleeve are known and are used primarily in the field of garden irrigation.
- the tap must be equipped with a specially designed extension. Within flats or houses it is now not possible to provide the differently designed taps and water fittings with such an extension piece, since this is not only not indicated for technical reasons, but also meets with design reservations.
- a hose nozzle is known, which is equipped with a rubber or plastic cap and can be pushed onto a tap.
- the object of the invention is therefore to provide an adapter coupling which not only ensures a water-conducting and as tight a connection as possible between a tap or the like and a hose, but also withstands the usual water pressure better.
- the adapter coupling according to the invention is designed in the form of a sleeve which is provided with a connection for the hose to be connected.
- This connection can be, for example, a connector equipped with an external thread, onto which the connecting element attached to the hose with the corresponding counter thread is screwed.
- the connection can have any known per se and any shape that is suitable for connecting with a hose. In the simplest case, this connection is an olive.
- the sleeve interior of the adapter coupling according to the invention is designed such that the water-emitting end of the water outlet of the tap is received therein or is located when the adapter coupling is placed on the tap etc.
- This sleeve can also be described as a kind of funnel into which the water outlet is inserted from the open side.
- the sleeve On its free, faucet-side edge, the sleeve has an elastic sealing ring with a central opening through which the water-discharging end is inserted.
- the sealing ring prevents the water that emerges from the water outlet and enters the interior of the sleeve from the sleeve in the direction of the opening or side from which the water outlet was introduced.
- the sealing ring has a circumferential sealing collar and a NEN annular base body, from the inner region of which the sealing sleeve extends approximately in the direction of insertion. This sealing sleeve is also inclined towards the center. This sealing sleeve is approximately funnel-shaped.
- the water outlet is to be introduced so far that the water-emitting end thereof is completely led through the opening formed by the free edge of the imaging sleeve and is located in the interior of the sleeve. Due to its elasticity, the sealing sleeve then clings to the outer surface of the water outlet behind the water-releasing end and thus seals the interior of the sleeve so that the water emerging from the water outlet cannot escape to the outside again at this point.
- the sealing ring also seals the inner surface of the sleeve against this sealing ring, so that no water can escape at the interface between the inner surface of the sleeve and the sealing ring.
- the sealing ring can be attached in any way in the interior of the sleeve, for example by gluing it to the sleeve or attached to it in some other way.
- the shape of the water outlet can in principle be of any type, for example cylindrical or rod-shaped with a more or less rectangular or polygonal cross section.
- the sealing sleeve adapts to these different shapes due to its elasticity.
- the shape of the sealing ring can be any. It only has to be dimensioned in such a way that the water outlet can be pushed through the central opening of the sealing sleeve and thereby expands it from the inside to the outside.
- the ring can be circular, square or polygonal.
- the cross-sectional shape of the annular base body can also be arbitrary, for example round, square or polygonal.
- the sealing ring consists of an elastic material, such as rubber.
- the sleeve expediently has an end wall which extends from the free edge of the sleeve in the direction of the water outlet and surrounds an opening which serves to introduce the water outlet.
- this end wall runs approximately perpendicular to the direction of insertion of the water outlet and thus expediently approximately perpendicular to the longitudinal axis of the sleeve.
- the sealing ring lies in the socket interior on the inside of the end wall or is supported there.
- the end wall is firmly connected to the sleeve or to the sleeve housing and contributes to the fact that the sealing ring is held in its position and is not pushed out or flung out of the sleeve interior by the water pressure prevailing in the sleeve interior when the tap is turned on.
- the sleeve and the end wall can be made of any suitable material, for example plastic or metal. Both parts are expediently injection molded and preferably injection molded in one piece.
- a support sleeve which rests against the inner circumferential surface of the sleeve, extends from the annular base body in the direction of insertion. In this way, the seal between the inner surface of the sleeve and the sealing ring is improved.
- the thickness of the body of the sealing sleeve preferably decreases or tapers starting from its base on the annular base body in the direction of its free edge. If the water outlet is now inserted into a sealing ring provided with such a sealing collar, the expansion naturally takes place first in the vicinity of the free edge of the sealing collar, which forms or surrounds the central opening of the sealing ring. The extent of the expansion depends on it on the dimensions of the inserted water outlet. Since the sealing cuff is very thin on its free edge in relation to the cross-section or the thickness, the sealing cuff, as its name suggests, lies close to its free edge in a cuff-like or collar-like manner on the outer surface or outer contour of the water outlet and runs parallel to it. When the tap is turned on, the adjacent area of the sealing collar is pressed against the water outlet by the water pressure in the socket area and ensures a better seal.
- At least one reinforcement unit is provided radially on the outside (or in other words, inside the socket) of the sealing sleeve, which also has an outer ring area and extends from there in the direction of insertion and is inclined towards the center and forms an opening at its free edge which forms the opening of the Sealing sleeve virtually surrounds the outside.
- this reinforcement unit is a reinforcement sleeve made of an elastic, stretchable material.
- the outer ring area is formed by the annular base body of the sealing ring.
- the reinforcement sleeve is thus inclined towards the center in the direction of insertion and thus runs around the sealing sleeve radially on the outside.
- the reinforcing sleeves are then laterally spaced apart and are therefore a certain distance apart. They are also preferably increasingly inclined towards the center when viewed from the outside inwards. For example, the outermost reinforcing lamella can extend parallel in the insertion direction. The next reinforcement collar located further inside is then slightly inclined towards the insertion direction. This inclination then increases with every further internal reinforcement sleeve.
- the sealing sleeve preferably extends in the insertion direction longer than the reinforcing sleeves. These reinforcement sleeves increase the sealing pressure on the sealing sleeve and thus the seal against the water outlet.
- sealing ring is provided with the reinforcement sleeves, the sealing sleeve and / or the support sleeve, then all of these elements are preferably made in one piece from an elastic material, for example rubber.
- the sleeve together with the connection and the sealing ring with all its elements, for example sealing sleeve, support sleeve, reinforcing sleeve and annular base body, is preferably rotationally symmetrical to the longitudinal axis, this longitudinal axis in particular coinciding with the direction of insertion.
- the sleeve can be approximately funnel-shaped or bell-shaped.
- the reinforcement sleeves there is preferably an approximately annular disk-shaped, preferably annular disk-shaped, pressure distribution lamella made of an elastic material.
- the elastic material can be rubber.
- This pressure distribution lamella preferably has an approximately semicircular extension on its radially outer edge or is turned inside out and upwards. This approach comes to rest in a circumferential groove in the support sleeve which is open towards the inside and is pressed in and held there by means of a snap ring. This groove is located in that area of the support sleeve which extends beyond the reinforcement sleeves.
- a second sealing ring is available from the sealing ring, which is also equipped with an annular base body.
- a second sealing collar extends inwards from the inner region of the second base body, which, like the first sealing collar, is inclined at an angle to the direction of insertion and thus towards the center.
- the angle between the longitudinal axis or the direction of insertion and both the sealing ring and the second sealing ring is approximately 20 to 80 °.
- the annular base body of the sealing ring and the second sealing ring on the one hand and the sealing sleeves of these two sealing rings on the other are approximately parallel to one another. At least one reinforcement unit is arranged between these two sealing rings.
- the reinforcement unit or the reinforcement units of this variant are annular disk reinforcements which have an outer, circumferential and continuous ring region, from which a plurality of tab-like tongues extend radially inward. Like the sealing sleeves, these tongues are inclined approximately at an angle to the direction of insertion and thus towards the center, and are only connected to the ring area at their base. The different tongues of a washer reinforcement therefore have no connection with one another.
- the ring disk reinforcements are expediently thin disks or platelets made of a plastic material. Since the tongues are only connected to the ring area at their base, this base or this connection area represents a film hinge, so to speak.
- the free ends of the tongues of an annular disk reinforcement lie approximately on a circle which forms the opening into which the water outlet is inserted .
- Washer reinforcements available, then there are two Washer reinforcements offset in such a way that the edge line of the tongues of the first washer reinforcement comes to lie on the center line of the tongues of the second washer reinforcement.
- the tongues of the two washer reinforcements have roughly the same dimensions.
- a slide which is displaceable in the direction of the longitudinal axis of the sleeve is located at the hose connection end of the sleeve.
- This slide has a pin-like central region, which extends in the axial direction or in the direction of the longitudinal axis and from which several, for example four, arm wings extend outwards. When viewed from above in the axial direction, this slide roughly forms a cross.
- the sleeve on the outside of the connection is preferably closed by a film.
- the slide In the non-used position or in the rest position, the slide is located in the interior of the sleeve sealed off by the film. If a water outlet is inserted into the sleeve, then this water outlet stops against this slide. If the water outlet is then pushed in further, the slide is moved in the axial direction and pierces or cuts through the film.
- This film is used on the one hand to indicate that the adapter coupling has not yet been used. On the other hand, it prevents moisture from penetrating through the connection into the interior of the socket.
- the film can be made of plastic or aluminum.
- the carriage preferably has a coaxial through bore in its central region, in which an axially displaceable needle is guided.
- the connection-side end of this needle tapers and is in the rest position in the area of this carriage or within the through hole.
- the other end of the needle is designed as a type of cover or plate that closes the free opening, which is formed by the sealing sleeve or is bordered by the free edge.
- a second film is preferably arranged parallel to the film described above in such a way that a container is formed between these films and is filled with a surfactant.
- a (further) container for a surfactant in the interior of the sleeve which expediently releases this surfactant only gradually.
- This container can be, for example, a sponge or the like.
- the sealing ring and the second sealing ring which each consist of the annular base body and the associated sealing sleeve, are preferably made in one piece from an elastic material, for example rubber.
- the sealing rings are furthermore preferably essentially rotationally symmetrical to the longitudinal axis. In this case, this preferably also applies to the sleeve and its cover.
- a sliding funnel is arranged radially on the inside (or, to put it another way, on the outside of the sleeve) of the sealing ring 11, which in turn has an outer circumferential continuous ring from which a plurality of tab-like tongues extend radially inward, which are also approximately oblique are inclined towards the direction of insertion and thus towards the center and their ends lie approximately on a circle which forms the opening into which the water outlet is inserted.
- This sliding funnel expediently rests with the tongues on the sealing collar of the sealing ring and is made of plastic, which should be as smooth as possible. This sliding funnel facilitates the insertion of the water outlet.
- an adapter coupling designed in this way can be easily pushed onto and placed on a wide variety of water outlets from taps in buildings etc.
- the adapter coupling according to the invention ensures that a seal against above the water pressure in the interior of the socket is reached and the water is also transported to the desired location through the connected hose.
- the adapter coupling according to the invention is preferably connected and used with a flat tube, for example a flat fabric tube. This prevents water from flowing back into the adapter coupling and further into the water pipe if a vacuum is created there, because when vacuum is applied, the flat hose is compressed by the external pressure. This is particularly advantageous if there is a container for a surfactant in the adapter coupling so that the surfactant cannot get into the water pipe.

- Fig. 18 is a plan view of a second washer reinforcement.
- the first variant of an adapter coupling 1 according to the invention shown in side view in FIG. 1 has a bell-shaped sleeve 2, which has a connection 3 in the form of a connecting piece provided with an external thread 15 and in the interior 7 of the sleeve (see FIGS. 2 and 3) the water-emitting end 4 a water outlet 5 is inserted or inserted in the insertion direction indicated by the arrow 6.
- the actual tap or its valve is not shown.
- a conventional water hose with a threaded cap or the like can be connected in a manner known per se.
- the sleeve 2 has at its free edge 8 an end wall 10 which extends towards the center or approximately perpendicular to the direction of insertion and surrounds an opening 9 through which the water outlet 5 is inserted.
- FIGS. 2 and 3 there is a sealing ring 11 in the sleeve interior 7, which rests with its annular base body 12 on the inside of the end wall 10 and is supported there.
- a circumferential support sleeve 13 extends in the insertion direction 6 and bears against the inner lateral surface 14 of the sleeve 2 or the sleeve housing.
- a circumferential sealing collar 16 extends in the insertion direction 6, which is inclined towards the center or towards the longitudinal axis 17 and forms a kind of funnel.
- the thickness of the body of the sealing collar 16 increases from their base 18 towards their free edge 19.
- the circumferential sealing sleeve 16 is configured in a quasi-sheet form. This circumferential free edge 19 surrounds the central opening 40 or forms it.
- circumferential reinforcing sleeves 20 also extend in the insertion direction between the sealing sleeve 16 and the support sleeve 13, starting from the annular base body 12. These reinforcement sleeves 20 extend less far into the sleeve interior 7 than the support sleeve 13 and the sealing sleeve 16.
- the outer reinforcement sleeve extends approximately parallel to the direction of insertion, while the inner reinforcement sleeves are increasingly inclined towards the longitudinal axis 17.
- the thickness of the body of the reinforcing sleeves increases more or less strongly from the annular base body 12 to its free edges or remains the same.
- the annular base body 12, together with the support sleeve 13, the sealing sleeve 16 and the reinforcing sleeves 20, is made in one piece from an elastic material, for example rubber, and is rotationally symmetrical to the longitudinal axis 17 anyway.
- the reinforcement cuffs 20 are spaced apart from one another; Between them and also to the support sleeve 13 and to the sealing sleeve 16 there is therefore a certain space 21, compare in particular FIG. 4, in which the sealing ring 11 is shown enlarged.
- the water outlet 5 inserted into the opening 9 expands the funnel-shaped sealing collar 16 and also the pressure distribution lamella 22.
- the water-emitting end 4 After the water-emitting end 4 has been pushed through the funnel formed by the sealing collar 16 or the opening 40, it nestles against the outer surface and outer contour of the water outlet 5 and seals the interior of the sleeve 7, so that no water between this sealing collar 16 and the Water outlet 5 can exit through the opening 9 from the sleeve interior 7.
- the water outlet 5 is inserted, however, not only the sealing sleeve 16 but also the reinforcing sleeves 20 are widened depending on its dimensions, and the more so, the further inside they are.
- the sealing sleeve interior 7 fills and the sealing sleeve 16 is pressed against the water outlet 5 in the region of its free edge 19.
- the water also presses the pressure distribution plate 22 and this in turn on the reinforcing sleeves 20, so that the downward and also radially inward pressure on the sealing sleeve 16 is increased and the sealing effect is thus improved.
- the sealing ring 1 1 can otherwise be glued to its outer surface and in particular on the outer surface of the support sleeve 13 to the inner surface 14 of the sleeve 2 or connected in some other way to keep it stationary. However, the sealing ring can only be inserted loosely into the sleeve 2. In this case, the end wall 10 prevents this sealing ring 11 from being pushed out.
- the sleeve 2 can be divided into an approximately hollow cylindrical section and a shortened bell section. For this purpose, these two parts have a cooperating thread 25. To insert the elastic sealing ring 1 1, screw the sleeve on, insert this sealing ring 1 1 and then screw the two parts of the sleeve back together.
- a circumferential ring 37 which is in contact with the inner circumferential surface 14 and is wedge-shaped in section and thus tapers in the insertion direction, can be made of an elastic material, e.g. Rubber, connect.
- the sealing ring 11 is then virtually clamped between the end wall 10 and this ring 37.
- the ring 37 is expediently against the sleeve 2 in the area in which the thread 25 is located. The circumferential ring 37 thus also seals this thread 25.
- the sleeve 2 can also be equipped on the outside with a winding 26 which extends from its free edge 8 to the area of the transition to the connection 3, so that the sleeve 2 can better withstand the water pressure prevailing in the interior.
- the wrapping 26 is of course also subdivided. The wrapping 26 is shown in Figs. 2 and 3 only hint or area.
- the sleeve 2 is equipped with one or more pins 27 on its outer wall.
- a tape or the like can be placed around this Pin 27 and the faucet looped or otherwise connected.
- a stop device 28 with an elastically designed stop 29 is provided in the socket space 7 in the vicinity of the connection 3 in order to limit the insertion path of the water outlet 5 and to slow it down gently.
- a trigger aid lever 39 which has an inner lever arm 30 and an outer lever arm 31 and is pivotably mounted about a snap ring 33.
- This snap ring 32 is located in an inward and thus approximately perpendicular to the insertion direction 6 groove 33, which is recessed in the inner region of the annular base body 12.
- the trigger aid lever runs in the area of the outer lever arm 31 approximately parallel to the outside of the sleeve 2, then swivels inward into the sleeve space 7 through the open side of the sleeve 2, lies against the snap ring 32 and then continues in the area of the inner lever arm 30 approximately parallel to the sealing collar 16. So that the trigger aid lever 27 can take this course, a corresponding width is provided in the end wall 10 from the opening 9 and extends radially outwards, through which the trigger aid lever 29 extends.
- the inner lever arm 30 is inserted into a pocket 34 recessed in the sealing sleeve 16. As can be seen in particular from FIG. 4, there is at least one circumferential sealing lip 35 on the inside or inner lateral surface of the sealing sleeve 16.
- the second variant of the adapter coupling according to the invention shown in FIG. 11, like the first variant described above, has a sleeve 2 and a connection 3.
- An annular ring wall 10 is clipped onto the free edge 8 of the sleeve 2.
- the free edge 8 has an outwardly projecting projection 41 which is clipped behind by an inwardly projecting projection 42 of the end wall 11.
- the end wall 11 defines an annular opening 9 into which the water outlet (not shown) is to be inserted.
- the end wall 10 has a band-like region 43 which extends in the direction of the longitudinal axis 17 and an associated band-like ring region 44 which extends approximately perpendicularly to the longitudinal axis 17 and is formed in section as a flat U, the opening of which faces the interior 7 of the sleeve .
- the annular base body 12 of the sealing ring 11 is inserted, from the inner area of which a sealing collar 16 extends into the interior of the sleeve interior 7, which is inclined towards the longitudinal axis 17.
- the angle of inclination between the longitudinal axis 17 and the sealing collar 16 is advantageously 20 to 80 °.
- the sealing collar 16 surrounds with its free edge 19 a central opening 40 and forms a kind of funnel into which the water outlet (not shown) should / can be inserted.
- a second sealing ring 1 1 ' On the side of the sealing ring 1 1 inclined towards the sleeve interior 7 there is a second sealing ring 1 1 ', which, like the sealing ring 1 1 has an annular base body 12 'and a second sealing collar 16'.
- This second sealing ring 1 1 ' lies on the inside of the sealing ring 1 1 or is oriented approximately parallel to it.
- the material thickness of the second sealing ring and the second sealing collar 16 ' is somewhat less or does not taper towards their free edge 19'. However, in the vicinity of its free edge 19 ', the second sealing collar 16' has a bulge 75 or a thickening which increases the contact pressure when the sealing collar 16 'is expanded.
- the base body 12 ' is designed approximately as a groove 76 in order to facilitate the pivoting of the sealing collar 16' when it expands.
- the two ring disk reinforcements 45 and 46 each have an outer, circumferential and continuous ring area 47 and 48, which is approximately U-shaped.
- the material of these washer reinforcements is thinned, so that film hinges are formed.
- the ring disk reinforcements 45 and 46 are provided with an edge 55 (see FIGS. 17, 18), by means of which the ring disk reinforcements 45 and 46 between the free edge 8 of the sleeve 2 and the radially outer one Edge of the U-shaped band-like area 44 of the end wall 10 is clamped, see FIG. 12.
- edge 55 of the washer reinforcement 45 there are a plurality of projections 56 which, when the two washer reinforcements 45, 46 are placed one on top of the other, protrude into corresponding recesses 57 in the washer reinforcement 46.
- These projections 56 and recesses 57 are arranged such that the washer reinforcements 45 and 46 or their tongues 49 and 50 are angularly offset, so that the dividing line 54 of the washer reinforcement 45 comes to lie approximately on the radial center line of the tongues 50 of the second washer reinforcement 46 .
- the free edges 51 of the tongues 49 and 50 form an opening 78 and 79, respectively, the diameter of the opening 79 formed in this way of the second annular disk reinforcement 46 being larger than the diameter 78 of the annular disk reinforcement 45.
- the washer reinforcements 45 and 46 are flat or flake-shaped and can be made of a plastic or a thin metal sheet. These annular disk reinforcements 45 and 46 are shown in FIGS. 17 and 18 in the upper region in the non-installed and thus in the unloaded state. If these annular disk reinforcements 45 and 46 are inserted between the sealing ring 11 and the second sealing ring 11 ', then the tongues 49 and 50 are angled and assume the position shown in FIG. 12.
- the sealing collar 16 and the second sealing collar 16 ' extend radially inward beyond the two annular disk reinforcements 45 and 46 and are brought together at their free edges 19 and 19' in such a way that they enclose these annular disk reinforcements 45 and 46 in a quasi-pocket-like manner.
- the sealing sleeves 16 and 16 ' can also be formed in one piece in the region of their free edges 19 and 19' and NEN-pointing U-shaped groove 83 for receiving the side edge of the cover 72 have.
- a sliding funnel 84 (see FIG. 12) can be arranged radially on the inside of the sealing ring 11 or its annular base body 12 and the associated sealing collar 16, which has an outer circumferential continuous ring 85, from which several tab-like tongues 86 follow extend radially inward, which, like the tongues of the annular disk reinforcements 45, 46, are inclined approximately obliquely to the insertion direction 6 and thus towards the center.
- the free ends of these tongues 86 lie approximately on a circle which surrounds the opening 40 into which the water outlet is inserted.
- the ring 85 is fitted between the radially inner edge of the U-shaped end wall 10 and the annular base body 12 of the sealing ring 1 1.
- the tongues 86 are similar in shape and configuration to the tongues 49 and 50 of the washer reinforcements 45 and 46 and are only articulated at their base on the ring 85. However, the ring 85 and the tongues 86 of the sliding funnel 84 are designed somewhat thicker, so that the sliding funnel inherently maintains or maintains its funnel shape and has the shape shown in FIG. 12.
- connection 3 (see Fig. 1 1) of the sleeve 2 of this second embodiment is a tubular portion 58, inside which a carriage 60 is guided in the axial direction and thus in the direction of the longitudinal axis 17 by a certain amount.
- This carriage 60 has a pin-like central region 61 which extends in the axial direction and from which four arm wings 62 extend radially outward.
- a through bore 63 is arranged coaxially to the pin-like central region 61.
- the slide 60 has the shape of a cross when viewed in the direction of the longitudinal axis 17. This slide 60 could also be described as a rocket with two wing pairs arranged approximately perpendicular to one another, which are referred to here as arm wings 62, compare in particular FIG. 14.
- the front edge 64 of these arm wings 62 is inclined away from the perpendicular to the longitudinal axis 17 and is sharply configured, so that these front edges 64 form a type of cutting edge which are used to cut through the film 65 (see FIG. 11).
- the arm wings 62 have towards the sleeve interior 7 in the axial direction and radially outwardly extending sections 66.
- the radially outwardly projecting edge 67 of these sections 66 has the effect that the axial displaceability of the slide 60 is limited, since this edge 67 against the inner free Edge 82 of the tubular section 58 of the connection 3 comes into abutment.
- the edges 80 of these sections 66 are sharply designed so that the water flowing through is braked as little as possible.
- a needle 70 is guided in the bore 63 of the carriage 60 so as to be displaceable in the axial direction.
- the connection-side end 71 of this needle 70 is in the rest position (corresponds to the position shown in FIG. 11) in this bore 63 in the carriage 60 and is designed as a tip 71.
- the other end of this needle 70 is designed as a kind of cover 72, which closes the free opening 40, which is bordered by the free edge 19 of the sealing sleeve 16.
- This cover 72 is approximately funnel-shaped and therefore seals the inside of the sleeve 7 on the water outlet side in the rest position from the outside.
- a second film 68 is present at the connection 3, a reservoir 69 being formed between these films, which is filled with a surfactant or with a surface-active agent.
- this water outlet comes into contact with the cover 72 and pushes it out of its position in the central opening 40 in the direction of the longitudinal axis 17 towards the connection 3.
- the needle 70 then comes with its connection-side end 71 or its tip to the film 65 and then pierces it and also the second film 68, since it is longer than the bore 63.
- the needle 70 is pushed in further, it comes with its cover 72 to lie in a corresponding recess 73 in the carriage 60.
- the slide 60 is then also axially displaced in the direction of the longitudinal axis 17 in the tubular section 58 and then tears open the foils 65 and 68 further.
- the water that comes under pressure through the water outlet into the sleeve nine space 7 can no longer escape through the central opening 40, since there at least the sealing collar 16 bears against the outer surface of the water outlet.
- the water can only get past the carriage 60 between its arm wings 62 through the connection 3 into the associated water hose, not shown, and takes the surfactant originally located in the reservoir 69 between the film 65 and the second film 68 or surfactant with or solves this.
- the water extinguishing agent can also be used to fight fires that should not otherwise be extinguished with water, for example burning oils, etc.
- the described adapter coupling according to the invention can be used on practically all common and customary taps or their water outlet be put on. Due to the sealing ring, it adapts to the different water outlets and withstands the water pressure.
- a water hose equipped with an adapter coupling according to the invention can be kept ready at a suitable location and, depending on the location of the source of the fire, the next tap can be connected to this water hose using the adapter coupling according to the invention.
- all maintenance costs and any exchange of extinguishing agents are eliminated.
- the space requirement of an adapter coupling or a combination of a water hose and an associated adapter coupling is extremely small.
- Firefighting can also take place from a greater and therefore safe distance due to the targeted use of the water jet.
- a commercially available syringe or the like can be attached to the end of the water hose opposite the adapter coupling and the water jet can thus be directed to the source of the fire in the desired shape and quantity.
- the adapter coupling is not limited to a hose for fire fighting, but can also be used for other purposes in a variety of ways, for example in the gardening and handicraft sector.
