Description

[0001] The invention relates to a dosing device, in particular a dosing dispenser, for dispensing fluids, in particular for dispensing soap, disinfectant, cream, lotion or the like, according to the preamble of claim 1. Furthermore, the invention relates to a method for removing and inserting a pumping device into a dosing device according to the preamble of claim 17.

[0002] Such dosing devices, also known as dispensers, can be filled with a variety of products, such as soaps (e.g., spray soaps, foam soaps, etc.), creams, disinfectants, or lotions. They are regularly used in sanitary and washroom facilities, i.e., wherever there is a need to provide soap, disinfectant, cream, or lotion according to the respective hygiene requirements. Such dosing devices have the advantage that a specific amount of, for example, soap or disinfectant can be dispensed by simply operating the pump or arm lever with the hand or elbow.

[0003] Such dosing devices typically comprise a housing or a housing base body that can be attached to a wall, for example, using a mounting device. Furthermore, such dosing devices comprise a pumping device, preferably with a dosing pump, an outlet panel protruding from the front for receiving and / or covering a pump outlet of the pumping device, and a pump actuation device, e.g., a pump or arm lever, by means of which the pumping device is operatively connected in the use position.

[0004] For reasons of hygiene and maintenance, the pumping device must be replaced regularly, which is always a relatively time-consuming and cumbersome procedure for the user.

[0005] Such a dosing device is already known from DE 10 2004 063 889 A1. In this dosing device, the pumping device can be replaced at the front. Specifically, in two embodiments, the outlet panel with the pumping device can be completely separated from the housing at the front, and in the third embodiment, the outlet panel is pivoted away about a pivot point. A design of this type, in which the outlet panel with the pump is completely removed or the outlet panel must be pivoted upwards, requires movable parts on the visible or front side. This, in addition to undesired displacement of individual parts due to improper handling, can also impair the design of the dosing devices and, for example, lead to undesirable uneven gaps.

[0006] Furthermore, EP 2 676 588 A2 discloses a dosing device having a U-shaped housing, wherein the outlet cover covers an outlet tube of a pumping device in a hood-like manner. The outlet cover has a rectangular base plate with a cutout and a hood-shaped cover arranged on a front side of the base plate, wherein rails are formed on a rear side of the base plate facing away from the front, which extend in a straight line and parallel to the mounting plate. These rails of the outlet cover are guided on correspondingly shaped guide webs of the basic structure of an actuating bracket unit, such that the outlet cover can be displaced upwards relative to the housing to create an opening for removing the pumping device. As a result, the pumping device can be removed essentially in a straight line towards the front without the dosing device having to be removed from the wall.Here, too, the same problems arise as in the previously assessed DE 10 2004 063 889 A1.

[0007] In contrast, it is the object of the present invention to provide a dosing device, in particular a dosing dispenser, for dispensing fluids, in particular for dispensing soap, disinfectant, cream, lotion or the like, which is constructed in a technically reliable manner, preferably without impairing the function or design of the dosing device, and by means of which the replacement and insertion of a pumping device can be carried out in a technically simple manner.

[0008] This object is achieved by the features of claim 1. Advantageous embodiments are the subject of the dependent claims which refer back thereto.

[0009] According to claim 1, a dosing device, in particular a dosing dispenser, for dispensing fluids, in particular for dispensing soap, disinfectant, cream, lotion, or the like, is provided. The dosing device comprises a housing base body having an outlet panel projecting from the front side thereof, relative to a use position of the dosing device, for receiving and / or covering a pump outlet of a removable pumping device. Furthermore, the dosing device comprises a pump actuating device, by means of which the pumping device is operatively connected in the use position, and a holding element coupled to the housing base body, preferably formed and / or arranged on the housing base body, to which the pumping device is detachably connected in the use position.According to the invention, the detachable connection between the pumping device and the holding element is designed such that, for removal, the pumping device can be disengaged from the holding element by a displacement movement directed rearward in the direction away from the front, so that the pumping device can then be displaced away from the holding element and removed from the dosing device by a displacement movement directed substantially downward in the vertical axis direction. Furthermore, for insertion, the pumping device can be brought into the region of the holding element by a displacement movement directed substantially upward in the vertical axis direction, so that the pumping device can then be brought into engagement with the holding element by a displacement movement directed forward in the direction of the front.

[0010] With such a solution, a pumping device can be replaced in a technically simple and functionally reliable manner, since no movable parts have to be provided on the visible or front side, so that there is no risk of unwanted displacement of individual parts due to improper handling and the design of the dosing devices cannot be impaired by, for example, undesirable uneven gap dimensions.

[0011] According to a particularly preferred embodiment, the detachable connection has at least one pump-side connecting element, to which a counter-connecting element is assigned on the holding element. Specifically, it is provided that each connecting element assigned to a counter-connecting element comes into engagement, in particular into a locking engagement, with the assigned counter-connecting element of the holding element during the forward displacement movement of the pump device towards the front, and comes out of engagement with the associated counter-connecting element of the holding element during the rearward displacement movement of the pump device away from the front. Furthermore, it is provided that the at least one pump-side connecting element is engaged by the holding element in the engaged position, thereby blocking a downward displacement movement of the pump device in the vertical axis direction.Furthermore, the at least one pump-side connecting element can be assigned to a recess on the retaining element side in the disengaged position, thereby enabling a downward displacement movement of the pump device in the vertical axis direction. Such a detachable connection with a pump-side connecting element, to which a counter-connecting element is assigned on the retaining element, enables a particularly reliable connection and detachability of the pump device and the retaining element.

[0012] For example, such a detachable connection consisting of a pump-side connecting element and a holding element-side connecting counter-element can be designed very easily as a snap-in connection, in particular as an overpressible snap-in connection, which is characterized by a high functional reliability.

[0013] According to a further preferred embodiment, the holding element can have two holding element rail regions which are opposite one another in the transverse direction, spaced apart from one another, and separated from one another by a central recess, said holding element rail regions comprising and / or forming the connecting counter-elements. According to a particularly preferred embodiment, these holding element rail regions form a sliding guide along which the pump-side connecting elements rest and / or are guided as they are moved into and out of the engagement position with the holding element-side connecting counter-element. The advantage of such a sliding guide is that the pump device, including its connecting elements, can then be brought into and out of engagement with the holding element-side connecting counter-elements in conjunction with such a sliding guide in a particularly secure manner.

[0014] According to another particularly preferred specific embodiment, the pumping device can have at least two transversely opposite pump-side projections, preferably projections forming sliding elements, as connecting elements, which protrude from the pumping device and are assigned to the holding element rail areas. Each holding element rail area has at least one preferably L-shaped wrap-around tab as a connecting counter element, which protrudes upwards from its base area in the vertical axis direction and rearwards away from the front in the longitudinal direction, which wrap-around tab engages around the respectively assigned pump-side projection in the engaged position and receives it between itself and the base area forming a support surface, preferably receiving it and releasably fixing it. With such a design, a particularly functionally reliable, releasable locking connection between the pumping device and the holding element can be achieved.Furthermore, adjoining the wraparound tab, rearwardly from the front as viewed in the longitudinal direction of the rail, is a recess on the retaining element side through which a respective pump-side projection can be passed, preferably without contact, during an upward or downward displacement movement as viewed in the vertical axis direction. Such a recess on the retaining element side, adjoining the wraparound tab, enables the upward or downward displacement movement for removing or inserting the pump device in a particularly reliable and simple manner.

[0015] Each holding element rail area can have at least two, preferably exactly two, wrap-around tabs spaced apart from one another in the longitudinal direction of the rail as holding element-side connecting counter-elements, to which a holding element-side recess is connected, viewed rearwardly from the front in the longitudinal direction of the rail. It is understood that each wrap-around tab is assigned a pump-side connecting counter-element. The provision of at least two wrap-around tabs spaced apart from one another in the longitudinal direction of the rail as holding element-side connecting counter-elements has the advantage that the pump device is then held functionally reliably and stably in the connected state with the holding element, thus providing a technically high-quality dosing device.

[0016] The retaining element can, in principle, be made of any suitable material, for example, a plastic material. However, a particularly preferred embodiment is one in which the retaining element is a sheet metal component, and the wraparound tabs are cut out of the base surface of the retaining element rail area and bent upwards.

[0017] As already mentioned several times before, the detachable connection between the pumping device and the holding element is preferably designed as a detachable locking connection, for example as an overpressible locking connection, which can only be locked or unlocked by applying a certain minimum force.

[0018] The pump actuation device can in principle also be designed in different ways, but is preferably formed by a preferably U-shaped pump lever pivotally mounted on the holding element. In conjunction with such a pump lever, it is particularly advantageous if the transversely opposite lever legs of a U-shaped pump lever, extending from the interior of the housing base body, are guided to the outside of the housing base body through a front-side slotted recess, preferably a slotted recess at least partially on the outlet panel side, which preferably limits the pivoting path. This ensures, on the one hand, easy operation of the pump lever from the outside. On the other hand, the internal part can interact with the pump device.

[0019] The retaining element is preferably secured, preferably releasably, to a rear side or to a rear region of the housing base body, relative to the use position of the dosing device. For example, the releasable securing is achieved by means of at least one screw connection.

[0020] According to a particularly preferred specific embodiment, the at least one pump-side connecting element is part of a mounting plate of the pump, to which a metering pump having the pump outlet, preferably an outlet tube as the pump outlet, is mounted. Such a mounting plate is ideally suited for forming the pump-side connecting elements. Furthermore, the metering pump can be easily and reliably mounted in such a mounting plate.

[0021] According to a particularly preferred embodiment, a suction pipe or suction hose of the dosing pump, in the use position, is inserted into a storage container that can be releasably connected to the pumping device, in particular a disposable or refillable bottle. This storage container can then be detached from the pumping device, for example, before it is removed, so that the operator can then simply grasp the pumping device to disengage it from the retaining element. The same applies analogously to the insertion process.

[0022] According to another particularly preferred embodiment, the outlet panel is designed and / or connected to the retaining element and / or the housing base body in a fixed and non-displaceable manner, in particular non-pivotable and / or non-displaceable, at least with regard to removal or replacement of the pumping device. As already mentioned above, such a measure can reliably prevent unwanted displacement of parts and negative design aspects.

[0023] The outlet baffle can fundamentally be designed in different ways, but is preferably designed as a hollow body with an inner cavity in which the pump outlet formed by an outlet tube is at least partially accommodated in the basic position. A continuous slot is provided on the underside of the outlet baffle, relative to the vertical axis, in the direction of the pumping device, through which slot the outlet tube can be displaced into or out of the inner cavity when the pumping device is displaced. With such a design, the outlet tube is well protected inside the outlet baffle, but on the other hand, the slot also ensures that the pumping device can be displaced without problems.

[0024] Particularly preferred is a configuration in which the outlet tube protrudes downward through the slot in the use position. This ensures the dispensing of a fluid in a particularly reliable manner, for example, by holding a hand under the outlet cover in the usual way.

[0025] According to another particularly preferred embodiment, the housing base body is open at least in some areas at the front, and the pumping device, in the use position, is arranged in the interior of the housing base body between transversely opposite side walls of the housing base body. This results in a substantially U-shaped configuration of the housing base body in a top view of the front. Such a housing base body has the advantage that the reservoir is clearly visible from the front. Furthermore, such a housing base body also enables easy access in connection with the removal and insertion of a pumping device.

[0026] Particularly preferably, the dosing device has a mounting bracket that allows the dosing device to be indirectly secured to a wall. Of course, direct mounting to a rear wall is also possible at any time.

[0027] A further object of the invention is to propose a method for removing and inserting a pumping device into a dosing device, in particular into a dosing device as described above, by means of which the replacement and insertion of a pumping device can be carried out in a technically simple manner.

[0028] This problem is solved with the features of claim 17.

[0029] According to claim 17, a method for removing and inserting a pumping device into a dosing device, in particular into a dosing device as described above, is proposed, in which the dosing device has a housing base body which, with respect to a use position of the dosing device, has an outlet panel protruding from the front thereof for receiving and / or covering a pump outlet of a removable pumping device. Furthermore, a pump actuating device is provided, by means of which the pumping device is operatively connected in the use position. Furthermore, a holding element is provided, which is coupled to the housing base body and is preferably formed and / or arranged on the housing base body and to which the pumping device is detachably connected in the use position.According to the invention, the detachable connection between the pumping device and the holding element is designed such that, for its removal, the pumping device is disengaged from the holding element by a displacement movement directed rearward in the direction away from the front, so that the pumping device is subsequently displaced away from the holding element by a displacement movement directed substantially downwards in the vertical axis direction and removed from the dosing device. Furthermore, it is provided that, for its insertion, the pumping device is brought into the region of the holding element by a displacement movement directed substantially upwards in the vertical axis direction, so that the pumping device is subsequently engaged with the holding element by a displacement movement directed forwards in the direction of the front.

[0030] The resulting advantages have already been explained in detail in connection with the dosing device according to the invention. To avoid repetition, reference is made to the above explanations.

[0031] The invention is described in more detail below by way of example with reference to a drawing.

[0032] They show: Fig. 1 a schematic side view of an exemplary embodiment of a dosing device according to the invention with a housing base body, Fig. 2 one of the Fig. 1 corresponding representation without the housing base, Fig. 3 an enlarged, perspective detailed view of the front of the dosing device with storage container, Fig. 4 a schematic perspective top view of the dosing device with the housing base removed, wherein the pumping device is in its use position, Fig. 5 a schematic, perspective bottom view corresponding to the Fig. 4, Fig. 6 one of the Fig. 3 corresponding representation with the reservoir removed at the beginning of the removal process of the pumping device, Fig. 7 a schematic side view of the dosing device according to the invention with the pumping device displaced backwards and downwards, Fig. 8 is a schematic, perspective and enlarged plan view showing the rearward and downward displaced state of the pumping device, Fig. 9 one of the Fig. 8 corresponding perspective bottom view, Fig. 10 is a schematic, perspective front view of the Fig. 7 to 9 shown rearward and downward shifted position of the pumping device, Fig. 11 a schematic side view of the pumping device now completely removed downwards, Fig. 12 a side view of the now completely removed pumping device, and Fig. 13 a perspective, enlarged detailed view of the removal state of the Fig. 12.

[0033] In the Fig. 1 shows schematically and by way of example an embodiment of a dosing device 1 according to the invention in a side view. This dosing device 1 has, as can be seen particularly from the enlarged, perspective front view of the Fig. 3, the housing base body 2 is U-shaped here, for example, which is open at the front 3 of the dosing device 1 and has a mounting bracket 5 on the rear 4 or can be connected to such a bracket. This mounting bracket 5 serves in the usual way, for example, for fastening the dosing device 1 to a wall (not shown here).

[0034] In the Fig. 1, the side walls or legs 6, 7 encompass a pumping device 9 or a storage container 10 on the left and right sides, while a base 8 connects the two legs 6, 7 to one another and covers or overlaps the pumping device 9 from above.

[0035] Furthermore, a U-shaped pump lever 11 is provided as a pump actuating device, which is pivotally mounted on a holding element 12 of the pump device 9 and is operatively connected to a metering pump 13 of the pump device 9 in the usual way.

[0036] An outlet aperture 14 protrudes from the front side 3 of the dosing device 1 or the housing base body 2, which serves to receive and / or cover an outlet tube 15 of the dosing pump 13 forming a pump outlet.

[0037] In the Fig. 2 is the representation of the Fig. 1 without the housing base body 2 and in the Fig. 4 is an enlarged perspective top view of the Fig. 2 without the housing base body 2 shown basic position. The Fig. 5 shows a bottom view of the Fig. 4 represents the basic position.

[0038] In this basic position, the pumping device 9 is detachably connected to the holding element 12, which is explained in more detail below: As this is particularly evident in the overview of Fig. 4 and Fig. 5, the holding element 12 has two holding element rail regions 17, 18 which are opposite one another in the transverse direction y, spaced apart from one another and separated from one another by a central recess 16 and which form a sliding guide along which a mounting plate 19 of the pumping device 9 is guided in a manner to be described, the mounting plate 19 simultaneously serving to hold the metering pump 13.

[0039] Each holding element rail region 17, 18 has at least two wrap-around tabs 20, spaced apart from one another in the longitudinal direction of the rail, as holding element-side connecting counter-elements, to which a holding element-side recess 21 is connected, viewed rearwardly in the longitudinal direction of the rail, away from the front side 3. Each of these wrap-around tabs 20, of which only one is shown on each holding element rail region 17, 18 in the example shown here, is assigned a pump-side connecting element formed by pump-side projections 22 that protrude from the mounting plate 19, viewed in the transverse direction y, and form sliding elements via which the mounting plate 19 can be slidably guided on the holding element rail regions 17, 18.

[0040] In the example shown here, two projections 22 are provided on each of the opposite sides, which are spaced apart from one another in the longitudinal direction of the rail and have a distance, with respect to the longitudinal direction of the rail, which corresponds to that of the recesses 21 on the holding element side, so that the mounting plate 19 together with its projections 22 projecting in the transverse direction y can be moved through these recesses 21 essentially without contact.

[0041] The wraparound tabs 20 are approximately L-shaped and have a shape that projects upwards and longitudinally backwards from the front side 3, which engages the respective associated pump-side projection 22 in the direction shown in the Fig. 4 and Fig. 5 and receives and releasably fixes the base surface of the retaining element rail region 17, 18, which forms a support surface. For this purpose, the connection between the projections 22 and the engagement tabs 20 is preferably designed as a releasable, for example, pressable, snap-in connection.

[0042] In the Fig. 4 and Fig. In the use position of the dosing device 1 or the pumping device 9 shown in Fig. 5, the projections 22 are thus in engagement with the wrap-around tabs 20 and the projections 22 are engaged by the holding element rail areas 17, 18 and thus by the holding element 12 in such a way that a displacement movement of the pumping device downwards (or also upwards) as seen in the vertical axis direction x is blocked.

[0043] If the pumping device 9 is to be replaced, the reservoir 10 is first removed from the pumping device 9, for example, unscrewed or pulled out of a clamp connection and removed downwards, so that a suction pipe 24 of the metering pump 13, which projects into the reservoir 10 in the use position, is free and access to the pumping device 9 or the mounting plate 19 is possible from the underside, relative to the vertical axis direction x. During this access, the pumping device 9 is then grasped at a suitable point, for example on the mounting plate 19 and / or on the suction pipe 24, and then disengaged from the gripping tabs 20 by a displacement movement directed backwards, in the direction away from the front side 3. This is done in such a way that, as shown in the Fig. 8 and Fig. 9, the projections 22 come to rest in the region of the recesses 21 and thereby a displacement movement of the pumping device 9 downwards as seen in the vertical axis direction x is released, so that the pumping device 9 together with the mounting plate 19 can be displaced downwards as seen in the vertical axis direction x, away from the holding element 12 ( Fig. 7 and Fig. 11) and can ultimately be removed from the dosing device 1 ( Fig. 12 and Fig. 13).

[0044] In order to prevent the outlet aperture 14 from blocking this downward displacement movement of the pumping device 9, as seen in the vertical axis direction x, with respect to the outlet tube 15 accommodated in the outlet aperture 14, the outlet aperture 14 has, which is particularly evident from the Fig. 5 and Fig. 9, on the underside of the outlet panel 14, relative to the vertical axis direction x, a slot 25 extending in the direction of the pumping device 9, through which the outlet tube 15 can be displaced into or out of the inner cavity of the outlet panel 14 upon displacement of the pumping device 9. In this case, the outlet tube 15 preferably protrudes in the use position, and as can be seen very well from the Fig. 6, with a tube end 26 through the slot 25 downwards.

[0045] As this is further shown in particular by the Fig. 8, the lever arms of the U-shaped pump lever 11, which are opposite in the transverse direction y, are guided from the interior of the housing base body 2 through a front-side slotted recess 27 which limits the pivoting path and which is at least partially a slotted recess on the outlet panel side, to the outside of the housing base body 2 (see also Fig. 9).

[0046] The retaining element 12 itself can be coupled to the housing base body 2 in various ways, for example, it can be integrally formed on the housing base body 2 or arranged thereon as a separate component or connected to it. The attachment can be detachable. The retaining element 12 can also be secured to the rear side 4 or to a rear region of the housing base body 2, for example, it can be screwed or locked there via a crossbar 28 of the retaining element 12, to name just one example.

[0047] It is understood that the insertion process of the pumping device 9 is carried out in reverse, although this is not shown in detail in the description of the figures. Specifically, the mounting plate 19 of the pumping device 9, including its projections 22, is threaded through the recesses 21 on the holding element side during an upward displacement movement in the vertical axis direction x. Subsequently, a displacement movement directed forward toward the front side 3, during which the projections 22 preferably slide along the holding element rail areas 17, 18, brings them into releasable locking engagement with the wraparound tabs 20.

[0048] Even if only two wrap-around tabs 20 assigned to the front recesses 21 are shown here, it is understood that corresponding wrap-around tabs 20 can also be assigned to the rear recesses 21 with respect to the front side 3, although this is not shown here for reasons of clarity.

[0049] As soon as the pumping device 9 has been fixed or locked in the basic or engagement position after insertion, the storage container 10 can be reconnected to the pumping device 9, as is shown, for example, in the Fig. 2 and Fig. 5 is shown.
