    Description: [0001] The invention relates to a hose, in particular a shower hose. Such a hose comprises an inner tube and a wound outer tube of metal surrounding the inner tube. Furthermore, such a hose comprises a connection device arranged at one end of the hose for connecting the hose to a fitting.
    A hose of this type is known for example from EP 0313 913 A2. There are within an outer sleeve, a water hose, two hoses for the promotion and output of various means and an electric cable for connection to an electronic unit arranged. At both ends of the hose are (not described in detail) multiple couplings with union nuts.
    A generic hose shows the document EP 2716 824 A2. There, a hose is disclosed with an inner tube made of an elastomeric material, in which inner tube a fluid is guided. A metal tube is helically wound around this inner tube. In order to be able to connect the hose at its ends, in particular to a fitting or the like, the hose is provided at at least one of its ends with a connection device.
    The tube known from EP 2716 824 A2 can only carry a single medium. In particular, it is not possible with this hose to transport different media simultaneously and separately from one another in the hose. However, especially in hospitals and nursing homes and in a home care of patients who suffer, for example, dementia, there is a need for hoses in which different media can be transported separately from each other.
    The invention has the object of developing a hose, in particular shower hose, of the type mentioned in that, if necessary, different means or fluids can be performed simultaneously and separately from each other through the hose, with ease of use or connectivity to the Hose ends should be guaranteed.
    The problem is solved by a hose having the features of claim 1. Advantageous further developments are defined in the dependent claims.
    According to the invention, a further inner tube is arranged inside the inner tube, preferably concentrically with respect to the inner tube. The further inner tube is connected in the region of the connection device to a connection part of the connection device, which connection part is provided and designed to hold the further inner tube in a predetermined radial position with respect to the inner tube, preferably in the mentioned concentric position. Furthermore, the connecting part, preferably centrally, an opening, which opening is formed and provided to a flow through a guided in the further inner tube medium. In addition, the connecting part in addition to said opening on at least one further opening, which further opening radially further outside than the opening is arranged and is designed to flow through a guided in the inner tube medium.
    By means of the invention, different media can be guided independently of one another in the inner tube and in the further inner tube, e.g. Water on the one hand and shampoo on the other. Both the inner tube and the further inner tube can be protected from damage by the surrounding, wound outer tube made of metal. The defined position of the inner tube with respect to the further inner tube, which is made possible by the connection part, can protect the two inner tubes against excessive wear, for example due to friction, and creates a defined space within the inner tube for guiding a further medium. It may also be possible by the separation of the inner tube and the further inner tube with a correspondingly formed wall of the further inner tube, in particular in terms of wall thickness and material, thermally decouple any guided in the inner tubes media, for example, hot water in the other inner tube and cold water in the inner tube.
    An inner diameter of the opening of the connecting part can advantageously correspond in terms of absolute value in about an inner diameter of the further inner tube to optionally provide a fluidically favorable flow space for a guided in the further inner tube medium.
    Preferably, the connecting part adjacent to the opening a plurality of, preferably circular, further openings, which are arranged around the opening. In particular, the further openings are located on an imaginary circle and preferably have approximately the same cross-section in terms of magnitude. This type of design of the connecting part can enable a particularly advantageous flow guidance of the medium guided in the inner tube in the region of the connecting part. In particular, unwanted turbulences and flow resistances can be avoided, while at the same time a circumferentially equally defined distance between an inner side of the inner tube and the further inner tube or its outer side can be defined.
    Without limiting the invention to this, a cleaning agent (for example, shampoo) or the like can be guided in the further inner tube, while water can be passed through the further openings of the connection part or through the inner tube itself, for example. The separation of the two flow spaces from each other thus allows a separate flow through the tube with two media, without it could lead to unwanted mixing of the two media.
    In another embodiment of the invention, an electrical line is passed through at least one of the further openings of the connecting part. For example, without limitation, the electrical conduit may be used to direct electrical power through the hose, for example, to drive an actuator located at another end of the hose. An electrical supply of lighting devices is possible by means of the electrical line. By guiding the electrical line through one of the further openings of the connecting part, the electrical line can be stable in position and guided in the interior of the inner tube. In particular, it is thereby virtually ruled out that the electrical line in the region of the connecting part is mechanically damaged, for example, by kinking.
    In an advantageous embodiment of the invention, the connecting part is at least partially formed as an inner fixing, in particular an inner sleeve, which inner fixing arranged in a region of a connection end of the further inner tube in the interior of the further inner tube or inserted into this.
    Preferably, the inner fixing is non-positively and / or positively held within the further inner tube. In this way, a simple type of connection between the connecting part and the further inner tube is made possible. The inner fixing element may have a sawtooth-like structure on its outer circumferential surface. In this case, the saw teeth can advantageously from a free end of the inner fixing in the direction of a radial broadening of the connecting part, in which radial broadening the at least two openings of the connecting part are arranged, have a radial slope. The term "radial slope" means that a radial extent of the inner fixing element increases from the free end of the inner fixing element in the direction of the radial broadening of the connecting part. The described sawtooth-like structure facilitates the insertion of the connecting part or the inner fixing element into the further inner tube. At the same time, an unintentional sliding out of the inner fixing element or connecting part from the further inner tube can be made more difficult or prevented by the special design of the saw teeth. Advantageously, in this type of connection to an addition of a material connection means, in particular an adhesive or Lotmittels be waived.
    Preferably, the connecting part in a region which is axially opposite the inner fixing element or the further inner tube formed as a further inner fixing, which further inner fixing element is provided and designed to connect to a further inner tube. In other words, this means that the inner fixing element and the further inner fixing element of the connecting part is formed approximately mirror-symmetrically to a plane which extends transversely with respect to a longitudinal axis of the hose and extends through a central axial region of the connecting part.
    It is thus possible to connect a further inner tube to the respective fixing element on both sides of the connecting part. This makes it possible to carry out a continuous fluid connection of the further inner tube with the additional further inner tube in a particularly simple manner.
    According to an advantageous development of the hose also includes an outer fixing element, which radially surrounds the outer fixing element in the region of a terminal end of the outer tube. The outer fixing element may in particular be designed as an outer sleeve, which is designed and provided for fixing the outer tube. Possible further properties and advantages of this embodiment will be discussed in more detail later in the description.
    Preferably, the connection device has a screw part which is arranged between the inner tube and the outer tube. On the face side, the screw part merges into a connecting flange, wherein the inner fixing element, the screw part and the outer fixing element overlap in a radial projection at least in regions, at least in pairs. The screw is intended and designed to enter by screwing a positive and / or positive connection with the outer tube. By this screwing a particularly stable and secure connection between screw and outer tube can be made. Preferably, the screw member is provided with (outer) threaded ridges, which can be screwed (from the inside) into the windings of the outer tube.
    To improve the connection of the inner tube to the connecting part or to the other components of the tube, an inner component can be inserted into the inner tube, in particular be pressed. This is preferably an inner sleeve. The inner component presses the inner tube from the inside substantially radially against the screw. As a result, the inner tube is particularly well and safely connected to the other components of the connection device or the hose. In an advantageous manner, the inner component can have a sawtooth structure or the like on an outer surface, as described for the inner fixing element and the further inner fixing element of the connecting part. By the sawtooth structure, comparable to the advantageously provided inner fixing element and the further inner fixing element of the connecting part, a connection between the inner component and the inner tube is improved or designed to be reliable.
    In an advantageous embodiment of the invention, an annular seal is provided on the end face on the connecting flange. Advantageously, the connecting part on at least one of its end faces on a preferably continuous, circular and axially projecting centering, which is provided and designed for radial positioning of the annular seal, for example by engaging in a central opening of the seal.
    In yet another further development of the hose according to the invention, the connecting part and the inner component and / or the inner component and the screw member and / or the connecting flange of the screw and the outer fixing element are each placed axially in a contact area against each other shock. Particularly preferably, a union nut radially encloses the connecting device, wherein the union nut for axial adaptation of the outer fixing to the flange of the screw and / or to an axial contact pressure of the screw to the inner component and / or to an axial contact pressure of the inner component of the Connecting part is formed and provided.
    Preferably, the union nut, for example by means of a radial projection, exerts an axial force on a preferably flange-shaped end of the outer fixing element, when the union nut is screwed to a corresponding threaded counterpart. The preferably flange-like end of the outer fixing element again exerts an axial pressure on the connecting flange of the screw part. The screw in turn pushes axially against one end of the inner component, which end is also formed flange. The inner component is finally, advantageously pressed with the flange-like end, axially against the connecting part. Thus, the union nut, for example by means of the radial projection, exert an axial holding force on the outer and inner components of the connection device when the union nut is bolted to a corresponding threaded counterpart. The outer tube, the inner tube and the further inner tube can be held by means of the axially pressed by the nut of the connection device components.
    Preferably, the inner tube and / or the further inner tube are formed in a plastic. Thus, the inner tube and / or the further inner tube can be designed to be particularly flexible.
    Further advantages and features of the invention will become apparent from the following description of exemplary embodiments with reference to the drawing. It shows:
    1 shows an inventive tube in a longitudinal section along the section line AA of Fig. 2.
    FIG. 2 shows the hose according to the invention from FIG. 1 in a cross section; FIG.
    3 shows the hose according to the invention from FIGS. 1 and 2 in an external view perpendicular to the longitudinal axis of the hose;
    4 shows the hose according to the invention in an oblique view;

    FIG. 7 shows a screw part for use in the hose according to FIGS. 1 to 4; FIG. and
    8 shows an outer fixing element for use in the tube according to FIGS. 1 to 4.
    In Fig. 1, an embodiment of an inventive hose 1 is shown in a longitudinal section along the section line AA of Fig. 2. The hose 1 comprises an outer hose 3, an inner hose 2, a further inner hose 6 and an electrical line 14. Furthermore, the hose 1 comprises in an end region 4 a connection device 5 with a connecting part 7, an inner component 18, a screw part 15, an outer one Fixing element 12 and a union nut 24th
    The outer tube 3 is formed as a winding tube with a folded profile (Agraff profile). In the context of the present invention, however, other profile shapes are possible. The outer tube 3 has in a conventional manner the function to protect the inner components of the tube 1 to the outside from damage. At the same time, due to its structure, the outer tube 3 only insignificantly affects the flexibility of the entire tube 1.
    The inner tube 2 and the further inner tube 6 are presently designed as plastic hoses. This gives the hose 1 while minimizing weight high flexibility. Both the outer tube 3 and the inner tubes 2, 6 and the electrical line 14 extend approximately parallel to each other in the direction of a longitudinal axis L of the tube 1. The outer tube 3, the inner tube 2 and the further inner tube 6 are concentric with each other with respect to the longitudinal axis L. arranged. Seen radially from the outside to the inside, the outer tube 3 surrounds the inner tubes 2, 6 and the electrical line 14. The inner tube 2 in turn encloses the electrical line 14 and the centrally arranged further inner tube 6.
    Without any restrictions, the inside diameter (inner diameter) of the further inner tube 6 is approximately half the size of the (inner) diameter of the inner tube 2. In the interior of the further inner tube 6, for example, a cleaning agent, in particular a shower or shampoo. In the inner tube 2, for example, water can be performed. The electrical lead 14 may, but is not limited to, transmit electrical power to a load, such as a lighting device or an actuator, disposed in a shower head (not shown) connected to the hose 1.
    At one of their respective ends of the outer tube 3, the inner tube 2, the further inner tube 6 and the electrical line 14 are connected to the connection device 5. An operation of the connecting device 5 and its components will be explained in more detail below.
    The connecting part 7 has a radial broadening 25 in an axially central region. Furthermore, the connecting part 7 is formed on an inner tube 6 facing the further side as an inner fixing element 7a. In this case, the inner fixing element 7a has the shape of an inner sleeve molded onto the remaining connecting part 7 with an outer peripheral surface, which outer peripheral surface has a sawtooth-like contour. The individual "saw teeth" have a radial slope from a free end 26a of the inner fixing element 7a in the direction of a radial widening 25 of the connecting part 7. The term "radial slope" means that a radial extent of the inner fixing element 7a increases from the free end 26a of the inner fixing element 7a in the direction of the radial widening 25 of the connecting part 7. The inner fixing element 7a is inserted into the interior of the further inner tube 6 or the further inner tube 6 is pushed over the inner fixing element 7a. The frictional and positive connection achieved between the further inner tube 6 and the inner fixing element 7a is effected or reinforced by the sawtooth-like contour of the outer circumferential surface of the inner fixing element 7a. A sliding down of the other inner tube 6 of the inner fixing 7a is thus almost impossible.
    On a side of the connecting part 7 opposite the further inner tube 6, the connecting part 7 has a further inner fixing element 7b, which has the same structure as the inner fixing element 7a. Only the "saw teeth" are mirrored with respect to a median plane M. The individual "saw teeth" correspondingly have a radial slope from a free end 26b of the further inner fixing element 7b in the direction of the radial broadening 25 of the connecting part 7. On the further inner fixing element 7b, an additional further inner tube 11 is pushed, whereby analogous to the connection between the further inner tube 6 and the inner fixing 7a a positive and positive connection between the additional further inner tube 11 and the further inner fixing element 7b is formed.
    The connecting part 7 has a continuous opening or an opening 8 in the axial direction, which opening or opening 8 has an approximately constant (clear) opening diameter dv. The (clear) opening diameter dv is in terms of amount approximately equal to the (inside) inside diameter of the other inner tube 6 and approximately equal to a (clear) inner diameter (not labeled) of the additional further inner tube 11. The connecting part 7 with the two inner fixing elements 7a, Thus, FIG. 7b does not represent any appreciable resistance for a medium which is guided in the interior of the additional further inner tube 11 or of the further inner tube 6. An advantage of this type of connection of the connecting part 7 with the additional further inner tube 11 or with the further inner tube 6 is that a potentially damaging effect on the materials, for example by gluing or soldering, does not take place. Also, this type of connection is particularly easy to manufacture.
    As can be seen in particular from Fig. 2, the connecting part 7 in addition to the approximately centrally disposed opening 8 - without limitation - eight further openings 8a, 8b, 8c, 8d, 8e, 8f, 8g, 8h, on an imaginary circle around the central opening 8 around in the radial widening 25 of the connecting part 7 are arranged. By way of example, the further openings 8a, 8b, 8c, 8d, 8e, 8f, 8g, 8h each have approximately the same circular cross-section in terms of amount. Through the further openings 8a, 8b, 8c, 8d, 8e, 8f, 8g, a medium, in particular water, can flow freely.
    Through the further opening 8h, the electrical line 14 is guided. The electrical line 14 is, as can be seen from Fig. 1, disposed within the inner tube 2. According to Fig. 1, the electrical line along the longitudinal axis L of the tube 1 is shown in one piece continuously. However, it is also within the scope of the invention if the electrical line 14 has corresponding coupling elements, which can be arranged in the region of the connecting device, and which can enable a multi-part of the electrical line 14.
    In the connection device 5, the inner component 18 is pressed into the inner tube 2. The inner component 18 is designed in the form of an inner sleeve and has, comparable to the inner fixing elements 7a, 7b, a sawtooth-like outer structure. By the sawtooth-like outer structure, the connection between the inner tube 2 and the inner component 18 is particularly safe and stable. At an end of the inner component 18 facing the connecting part 7, this widens radially in the form of steps to form a radial intermediate step 18b and a flange 18a. The intermediate stage 18b of the inner component 18 can serve as an axial stop for the inner tube 2. The flange 18a of the inner component 18 and the radial broadening 25 of the connecting part 7 are axially abutting each other and close radially outwardly flush. A clear cross section of the inner component 18 increases in an end region 18c or the inner component 18 opens radially outwards in the end region 18c so that the further openings 8a, 8b, 8c, 8d, 8e, 8f, 8g, 8h remain free.
    The radial widening 25 of the connecting part 7 has on an inner tube 2 axially facing away from an axially projecting annular centering web 20 which is provided and designed for radial positioning of a likewise annular seal 19. The annular seal 19 has an opening (not labeled) into which the centering web 20 engages. The seal 19 seals the hose 1 in the region of the connection device 5.
    Radially between the inner tube 2 and the outer tube 3, the screw 15 is arranged. The screw 15 has special thread ridges 17 which engage in windings of the outer tube 3 and thus connect the screw 15 with the outer tube 3 non-positively and positively. The screw member 15 has a radially widening step 15 a and continues, comparable to the inner component 18, in the connecting device in a radially expanded connecting flange 16 continues. The radial expansion takes place, as in the case of the inner component 18, stepped. The radially widening step 15a can serve as an axial stop for the outer tube 3. Axially against the connecting flange 16 of the screw 15, the annular seal 19 is placed. The connecting flange 16 and the seal 19 close radially outwardly flush. The screw 15 engages in the region of the connecting flange 16 and the radially widening step 15 a both the radial broadening 25 of the connecting part 7 and the flange 18 a of the inner component 18th
    In a region 13 of a terminal end of the outer tube 3, the outer fixing element 12 is arranged, which radially surrounds the outer tube 3 in this area. The outer fixing element 12 is designed as a sleeve and has a radial widening 12a at an end arranged in the connecting device 5. In the area of this radial widening 12 a, the outer fixing element 12 is applied axially to the connecting flange 16 of the screw part 15. The seal 19, the connection flange 16 of the screw 15 and the radial expansion 12a of the outer fixing element 12 close radially outwardly flush.
    The union nut 24, which on its side facing the outer tube 3 has a radially inwardly directed retaining projection 24a, surrounds the entire connecting device 5. In an assembled state, the union nut 24 is screwed into a corresponding threaded counterpart (not shown). The union nut 24 in the assembled state presses the outer fixing element 12 or the region of the radial widening 12a of the outer fixing element 12 axially in a contact region 23 against the connection flange 16 of the screw part 15. Thus, the outer tube 3 connected to the screw part 15 is held in the connection device 5 , The radially widening step 15a of the screw member 15 in turn is pressed indirectly by the union nut 24 in a contact region 22 in the axial direction against the flange 18a of the inner component 18. The flange 18a is, as already described above, placed in a contact region 21 axially in shock against the radial widening 25 of the connecting part 7.
    Thus, the union nut 24 in the assembled state also connects the inner tube 2 connected to the inner component 18 to the connection device 5 and to the connection part 7. The further inner tube 6 is, as described above, connected to the connection part 7 by means of its inner fixation element 7a , The same applies to the additional further inner tube 11 with respect to the further inner fixing element 7b.
    In Figs. 3 and 4 are exterior views of the hose 1 are shown, showing the hose 1 from different perspectives. In order to avoid content repetition, reference is made to the detailed description of the hose 1 with reference to FIGS. 1 and 2.
    Fig. 5 shows in an enlarged detail the connecting part 7 with the inner fixing 7a, the other inner fixing 7b and the radial widening 25. Furthermore, in Fig. 5, the centering web 20 and the central opening 8 and the other openings 8d , 8h. Good to see the sawtooth structure of the outer peripheral surface of the inner fixing 7a and the other inner fixing 7b, which can allow a particularly stable and secure connection between the other inner tube 6 and the connecting part 7.
    In Fig. 6, the inner component 18 is shown with the flange 18a, the intermediate stage 18b and the radial opening of the inner component 18 in the end portion 18c in an enlargement. Like the two inner fixing components 7a, 7b, the inner component has on its outer circumferential surface a sawtooth-like structure by means of which the inner tube 2 can be held on the inner component 18.
    Fig. 7 shows an enlarged view of the screw 15. The screw 15 has threaded ridges 17, with which it can engage in the windings of the wound outer tube 3. At one end, the screw member 15 has a radially widening step 15a and a connecting flange 16, the function of which has already been described above.
    In Fig. 8, the outer fixing member 12 is shown having the radial expansion 12a at one end.
