Description

Technical Field

[0001] The present invention relates to a hose connection having at least one hose receiving portion into which a hose end can be introduced. For example, the hose connection includes a plurality of hose receiving portions into which hose ends can be respectively introduced. Background Art

[0002] The hose ends of a plurality of hoses can be connected to one such hose connection. For example, an outlet and one or more inlets are connected, and in the inlets, for example, cold water and hot water are introduced into a mixing chamber separately from each other.

[0003] For such hose connections, different connections are known, which couple the respective hose ends to the hose receiving portions. For example, an adhesive-thread connection or a laterally insertable metal retaining plate is provided for this purpose.

[0004] However, these connections have the disadvantages that their manufacture is cumbersome, their operation is cumbersome, or they are difficult to disassemble or non-disassemblable. Summary of the Invention

[0005] Therefore, the object of the present invention is to improve the hose connection and to facilitate the connection of the hose end to the hose connection.

[0006] The solution to this task lies in particular in a hose connection having at least one hose receiving portion into which a hose end can be introduced, a clip passing through the at least one hose receiving portion in order to engage in a clip receiving portion of the hose end, wherein the clip is configured to self-retain on the at least one hose receiving portion.

[0007] For example, in one embodiment, it is provided that the at least one hose receiving portion is formed on a hose wrapping or a housing, and the clip passes through the housing in the region of the hose receiving portion, in particular through a locking opening of the housing, wherein the clip is configured to self-retain on the housing in the region of the hose receiving portion.

[0008] The present invention is based on the recognition that by using a clip, the connection of one or more hose ends to the hose connection is facilitated, the clip being configured to self-retain on the hose receiving portion or being clipable onto the hose receiving portion and at the same time passing through the hose receiving portion in such a way that the clip engages in a clip receiving portion on the hose end. For example, the clip can be detachably clipped onto the hose receiving portion. The technical effect of the described hose connection is therefore in particular to facilitate an adhesive-free connection of the hose end to the hose connection or the replacement of the hose end on the hose connection.

[0009] In another design, it is stipulated that the clip is integrally constructed. Additionally, in another design, it is stipulated that the clip is formed from an elastic material.

[0010] The elastic properties of the clip allow the clip to be form - fittingly connected to the hose receptacle or the housing. In particular, the clip can be laterally mounted on the hose receptacle or the housing such that the clip surrounds the hose receptacle or the housing. This makes the installation of the clip onto the hose receptacle or the housing and the removal from the hose receptacle or the housing easier.

[0011] In one design, it is stipulated that the clip includes at least one support surface that at least partially supports on the housing, preferably at least partially surrounds the housing.

[0012] The support surface of the clip, preferably formed from an elastic material, provides a particularly simple means to surround the housing and to self - retainingly lock or clamp the clip onto the hose receptacle or the housing.

[0013] In one design, it is stipulated that the clip includes at least one locking tab, wherein the at least one locking tab passes through at least one hose receptacle, in particular through a plurality of hose receptacles.

[0014] For example, the clip includes a plurality of locking tabs that each pass through one or more locking openings and through one or more hose receptacles. This can ensure that the hose end is reliably held in the hose receptacle. Additionally, a plurality of hose ends can thus be held in the respective hose receptacles in a simple manner by means of a single clip.

[0015] In one design, it is stipulated that the at least one locking tab projects from the at least one support surface, and / or the at least one support surface surrounds the at least one locking tab.

[0016] In this design, if the locking tab passes through or fits into the locking opening, then the support surface supports beside the locking opening and locks the clip onto the hose receptacle or the housing or imparts a firm hold of the locked clip on the hose receptacle or the housing.

[0017] In one design, it is stipulated that the clip surrounds the at least one hose receptacle over at least half of the circumference.

[0018] For this purpose, the clip can, for example, surround a plurality of hose receptacles and each partially support on the plurality of hose receptacles or the respective housing. This has the advantage that the locked clip is form - fittingly or force - fittingly connected to one or more hose receptacles or one or more housings. Thus, it is allowed to firmly hold the clip on one or more housings or one or more hose receptacles.

[0019] In one design, it is stipulated that the clip includes a plurality of locking tabs, and among them, one of the plurality of locking tabs extends beyond the other locking tabs in the longitudinal direction.

[0020] For example, the clip includes two outer locking tabs (surrounding and passing through one or more hose ends) and one longer intermediate locking tab (passing through one or more hose ends). The intermediate locking tab can pre - fix or position the hose end when the locking clip is pushed in, so that the clip can be simply placed.

[0021] In one design, it is stipulated that the clip has at least one locking device, and the at least one locking device locks the clip in at least one movement direction of the clip, preferably transversely to the hose end introduction direction.

[0022] Therefore, it can be prevented that the clip is completely loosened from the hose receiving part when the clip is pulled out from the hose receiving part.

[0023] In one design, it is stipulated that the at least one locking device acts on a recess on or in the area of the hose receiving part from the rear. This has the advantage of simplifying the installation and locking of the clip on the hose receiving part.

[0024] In one design, it is stipulated that the at least one locking device locks the clip in the locked position, and the clip does not pass through the at least one hose receiving part in the locked position.

[0025] For example, the at least one locking device is constructed in an extension of at least one corresponding locking tab. In particular, the corresponding locking device can be constructed in an extension of the corresponding outer locking tab among the plurality of locking tabs. Thereby, the clip can be held in the locked position while the hose end can be introduced into the hose receiving part. This prevents the clip from being lost when introducing or replacing the hose end. Description of the Drawings

[0035] Figure 1 shows a three-dimensional exploded view of the hose joint 1. Figure 2 shows a three-dimensional view of the hose joint in an assembled state. The same features are provided with the same reference numerals. The hose joint 1 includes a hose receiving portion 3a into which a hose end portion 4a can be introduced. The hose joint 1 further has a second hose receiving portion 3b and a third hose receiving portion 3c into which corresponding second hose end portions 4b and third hose end portions 4c can be introduced. The hose joint 1 includes a clip 6 which, in the assembled state with the hose receiving portion 3a and the clip 6, passes through the hose receiving portion 3a. Similarly, the clip 6 passes through the second hose receiving portion 3b and the third hose receiving portion 3c.

[0036] The hose receiving portions 3a, 3b, 3c are formed on corresponding first, second, and third housings 2a, 2b, 2c. The housings 2a, 2b, 3c each include at least one locking opening. In the illustrated example, the first housing 2a and the second housing 2b each include one first locking opening 5a, 5b and one second locking opening 10a, 10b.

[0037] In the assembled state, the clip 6 passes through the first housing 2a and the second housing 2b in the regions of the first hose receiving portion 3a and the second hose receiving portion 3b, in which regions the clip 6 passes through or is fitted into the locking openings 5a, 5b, 10a, 10b.

[0038] In the assembled state of the clip 6 and the hose joint 1, the clip 6 is configured to be self-retained in the regions of the hose receiving portions 3a, 3b. The clip 6 is self-retained on the first housing 2a and the second housing 2b.

[0039] Figure 3The clip 6 in the first embodiment is shown in a three-dimensional view. The clip 6 is integrally constructed. The clip 6 includes a bearing surface 7. The clip 6 includes two outer locking tabs 8a, 8b and one intermediate locking tab 8c. At least the outer locking tabs 8a, 8b project from the bearing surface 7. At least the outer locking tabs 8a, 8b are surrounded by the bearing surface 7. The locking tabs 8a, 8b, 8c are designed in an elongated shape. The intermediate locking tab 8c is longer than the outer locking tabs 8a, 8b. In other words: the intermediate locking tab 8c projects beyond the outer locking tabs 8a, 8b along the longitudinal direction of the locking tabs 8a, 8b, 8c.

[0040] The bearing surface 7 includes a first bearing surface 7a, a second bearing surface 7b and a third bearing surface 7c. The first outer locking tab 8a projects from the first bearing surface 7a or is surrounded by the first bearing surface 7a. The second outer locking tab 8b projects from the second bearing surface 7b or is surrounded by the second bearing surface 7b. The intermediate locking tab 8c is arranged between the first bearing surface 7a and the second bearing surface 7b. In the assembled state of the clip 6 and the hose connection 1, the first bearing surface 7a bears on the first housing 2a, and the second bearing surface 7b bears on the second housing 2b.

[0041] The intermediate locking tab 8c projects beyond the bearing surface 7 or the first bearing surface 7a and the second bearing surface 7b in the longitudinal direction in the illustrated example, wherein the bearing surface 7 or the first bearing surface 7a and the second bearing surface 7b have a bend in the longitudinal direction.

[0042] In the illustrated example, the intermediate locking tab 8c projects from the third bearing surface 7c or is surrounded by the third bearing surface.

[0043] As can be seen in Figure 1 and Figure 2 , the clip 6 bears on the hose connection 1 in the region of the first hose receiving portion 3a. Similarly, the clip 6 bears on the hose connection 1 in the region of the second hose receiving portion 3b. In other words: the clip 6 bears on the housings 2a, 2b in the regions of the hose receiving portions 3a, 3b.

[0044] The clip 6 surrounds the first hose receiving portion 3a and the second hose receiving portion 3b or the first housing 2a and the second housing 2b. The clip 6 or the bearing surface 7 surrounds the first hose receiving portion 3a and the second hose receiving portion 3b or the first housing 2a and the second housing 2b over more than half of the circumference of the first hose receiving portion 3a and the second hose receiving portion 3b or the first housing 2a and the second housing 2b, respectively.

[0045] The clip 6 is at least partially formed of an elastic material. The clip 6 can be introduced into the locking openings 5a, 5b, 10a, 10b in a transverse direction transverse to the introduction direction of the hose ends 3a, 3b. The clip 6 can be clamped to the housings 2a, 2b by its elastic shape. The transverse direction corresponds to the longitudinal direction of the elongate locking tabs in the assembled state.

[0046] The middle locking tab 8c can be introduced into the second locking openings 10a, 10b without the clip 6 or the support surface 7 surrounding the housings 2a, 2b. Thus, when the clip 6 is introduced into the first locking openings 5a, 5b of the housings 2a, 2b, the middle locking tab 8c is a guiding element.

[0047] In the assembled state, the outer locking tabs 8a, 8b pass through one of the first locking openings 5a, 5b in the housings 2a, 2b respectively. The middle locking tab 8c passes through the second locking openings 10a, 10b in the housings 2a, 2b. In addition, the middle locking tab passes through the third locking opening 11 in the third housing 2c in the region of the third hose receiving part 3c (see Figure 4a , Figure 4b and Figure 4c ).

[0048] The first outer locking tab 8a is snapped into the first clip receiving part 9a of the first hose end 4a in the assembled state. In the illustrated example, the first clip receiving part 9a is configured as a circumferential taper of the first hose end 4a. In the assembled state, the second outer locking tab 8b is snapped into the second clip receiving part 9b of the second hose end 4b or into the circumferential taper of the second hose end 4b. The middle locking tab 8c is also snapped into the third clip receiving part 9c of the third hose end 4c or into the circumferential taper of the third hose end 4c in the assembled state. In addition, the middle locking tab 8c is snapped into the first clip receiving part 9a and the second clip receiving part 9b respectively or into the corresponding circumferential tapers of the first hose end 4a and the second hose end 4b or into additional clip receiving parts of the first hose end 4a and the second hose end 4b in the assembled state.

[0049] Before the outer locking tabs 8a, 8b are snapped into the locking openings 5a, 5b or into the first clip receiving part 9a and the second clip receiving part 9b, the middle locking tab 8c is snapped into the first clip receiving part 9a and the second clip receiving part 9b of the hose ends 4a, 4b or into additional clip receiving parts during clip introduction. Thereby, the middle locking tab 8c can pre-fix the first hose end 4a and the second hose end 4b before the outer locking tabs 8a, 8b are snapped into the first clip receiving part 9a and the second clip receiving part 9b.

[0050] Figure 4a , Figure 4b and Figure 4c show three cross-sectional views of the hose connection 1 in a state assembled with the clip 6 and the hose ends 4a, 4b. Identical features are provided with identical reference numerals.

[0051] Figure 5 The clip 6 in the second embodiment is shown in a three-dimensional view. Identical features are provided with identical reference numerals. In addition to the features of the clip 6 described with reference to Figure 3 , the clip 6 further includes a first locking device 12a and a second locking device 12b or a first anti-pull-out device 12a and a second anti-pull-out device 12b. The locking devices 12a and 12b are respectively constructed in an extension of one of the two outer locking tabs 8a and 8b or in an extension in the longitudinal direction of one of the first support surface 7a and the second support surface 7b. The locking devices 12a and 12b are mounted on the support surface 7 or respectively on one of the first support surface 7a and the second support surface 7b. The locking devices 12a and 12b project beyond the locking tabs 8a, 8b, 8c in the longitudinal direction of the locking tabs 8a, 8b, 8c. The first locking device 12a includes a first protrusion 13a. The second locking device 12b includes a second protrusion 13b.

[0052] Figure 6a and Figure 6b show a three-dimensional view of the hose connection 1 having the clip 6 in the second embodiment. Figure 6c and Figure 6d show a cross-sectional view of the hose connection 1 having the clip 6 in the second embodiment. Identical features are provided with identical reference numerals.

[0053] As shown in Figures 6a to 6d , the first housing 2a has a side recess or a locking opening in the region of the first hose receiving portion 3a. In the assembled state of the clip 6 and the hose connection 1, the locking device 12a acts behind the side recess or engages in the locking opening of the first housing 2a. For this purpose, the first locking device 12a has a protrusion 13a corresponding to the side recess or the locking opening of the first housing 2a. Similarly, in the assembled state of the clip 6 and the hose connection 1, the locking device 12b acts behind the side recess or the locking opening of the second housing 2b. The second locking device 12b has a protrusion 13b corresponding to the side recess or the locking opening of the second housing 2b for this purpose.

[0054] As Figures 6a to 6dAs shown, the latching devices 12a, 12b latch the clip 6 in the latched position. The latching devices 12a, 12b prevent the clip 6 from being easily released from the housings 2a, 2b or from releasing itself. In the latched position, none of the locking tabs 8a, 8b, 8c engages in or passes through one of the hose receiving portions 3a, 3b, 3c of the hose fitting 1. In particular, the middle locking tab 8c does not pass through the hose receiving portions 3a and 3b. In the example shown, the latching devices 12a, 12b project beyond the locking tabs 8a, 8b, 8c in the longitudinal direction of the locking tabs 8a, 8b, 8c (in particular in the longitudinal direction transverse to the insertion direction for inserting the hose end into one of the hose receiving portions 3a, 3b). In other words: the respective projections 13a, 13b of the latching devices 12a, 12b project beyond the locking tabs 8a, 8b, 8c in the longitudinal direction of the locking tabs 8a, 8b, 8c.

[0055] In the second embodiment, the clip 6 allows the clip 6 to be positioned or locked on the housings 2a, 2b such that the clip 6 does not pass through the hose receiving portions 3a, 3b and thus the respective hose ends can be inserted into the hose receiving portions.
