Abstract

The tap is fittable in an opening of the carrier with a pipe axis running approximately vertically to the carrier upper side. At least one operating component is provided for a water outlet valve and mixt. device. The straight pipe area is displaceably arranged in the carrier opening in a guide (12) in the direction of the pipe axis (22). It can be raised from a lower position, in which the water outlet aperture (34) is directly adjacent the level of the carrier upper side, into an upper usage position, in which the water outlet aperture is at a greater distance over the level of the carrier upper side.

Description

Conventional so-called mixer taps, e.g. B. for kitchen sinks, often have an approximately circular cylindrical housing, which is mounted with a vertical housing axis in an opening of a sink, a washbasin or a table or cover plate accommodating a built-in sink or a basin, accommodates a mixing valve cartridge or cartridge and a mostly lever-like one on top , tilting and swiveling control element for the mixing valve cartridge; in addition, a crane-like water outlet branches off from the housing and can be pivoted together with a housing part around the cylinder axis. Mixer taps with a crane-like water outlet which can be pivoted about a vertical axis and two separate and also separately attachable water valves for cold and hot water, each with an operating element, are also known.

The invention is now concerned with a mixer tap water outlet device for mounting on a horizontal, plate-like support, with a straight tube area which surrounds a water outlet line leading to a water outlet opening and can be mounted in an opening of the support with a pipe axis running approximately perpendicular to the top of the support, and with at least one control element for a water outlet valve and mixing device.

Known mixer tap water spouts of this type, although most widely used, are often found to be bothersome because they go up considerably above the support (be it a sink, a built-in sink or the cover plate of a built-under cupboard of a fitted kitchen, a bathroom fixture or the like) protrude and therefore not only interfere with handling in the area of the water outlet device (many dishes have been damaged or even destroyed by striking such a water outlet device), but z. B. also be perceived as annoying when larger objects are to be placed on the sink, the cover plate or the like. Also, such a known water outlet device may make it impossible to fully open a window behind it, i.e. H. to open this window or a window sash completely, namely whenever the window parapet is not at a level above the highest point of the water outlet device; especially behind a sink you would often like to place a window in a kitchen.

The invention was therefore based on the object to provide a water outlet device of the type mentioned above, by which the disadvantages listed above can be avoided, which is possible if, according to the invention, the straight pipe area of the water outlet device is in a firmly attachable guide in the carrier opening in the direction of its Axis slidably guided and can be raised from a lower position, in which the water outlet opening is directly adjacent to the level of the upper side of the carrier, into an upper position of use, in which the water outlet opening is located at a greater distance above the level of the upper side of the carrier.

In a water outlet device according to the invention, the part or parts which have or have the disadvantages listed above can be lowered at least to such an extent that these impairments are eliminated, and in particular the construction is designed such that this part or parts can be lowered as far as the carrier holding the water outlet device allows.

If a plate-like support is mentioned above, this naturally also includes an area of a sink or built-in sink, a built-in basin, such as a wash basin, or the like, which has an at least approximately horizontal upper side.

In the water outlet line leading to the water outlet opening, it can, as far as this runs in the straight tube region mentioned, be the channel formed by this tube region itself, but also a z. B. tubular line or two such lines (one for cold and one for hot water), which runs or run in this pipe area.

It follows from the above that the control element or the control elements does not necessarily have to be integrated into the actual water outlet device; a correspondingly flat operating element can, without having to forego the advantages of the invention, be readily arranged next to the straight tube region mentioned on the plate-like support or at another location suitable for operation.

If it is mentioned above that in the lower position of the straight tube region the water outlet opening is directly adjacent to the level of the upper side of the support, this also includes cases in which the region of the water outlet device comprising the water outlet opening is somewhat below this level - if the straight pipe area z. B. is arranged on a so-called battery bank of a sink, in its lower position the area provided with the water outlet opening of the water outlet device can also protrude somewhat into a basin of the sink adjacent to the battery bank. Also, the area of the water outlet device provided with the water outlet opening can rest on the top of the sink, e.g. B. on the top of the aforementioned battery bank.

So that the water outlet opening can be brought at least in the upper position of use of the water outlet device over various locations in the vicinity of the latter, it is advisable to design the straight tube region and its guide such that the tube region is rotatable about its tube axis in the guide.

If the straight tube section deviates from the circular shape at any point on its outer circumference (in cross section), the guide could have the shape of a flat surface, a rib extending in the vertical direction or the like; However, embodiments are preferred in which the guide surrounds the straight tube area all around, especially with regard to the desired rotatability of the straight tube area about its axis. In the case of a guide encompassing the tube area, as is particularly preferred, the guide can also be provided with an elastic seal which lies all around on the outer circumference of the straight tube area are not only prevented by the fact that water, other liquids or dirt can get down between the guide and the tube area, but with such an elastic seal can also be achieved that the water outlet device is in its upper position of use, when you lets go, either not at all or only slowly sinks and does not fall into its lower position.

However, embodiments are preferred in which the water outlet device is held in its upper position of use by a locking device, i. H. Embodiments in which a locking device is provided to hold the straight tube region in its upper position and this is designed such that the straight tube region can be lowered manually into its lower position. This locking device could, for. B. designed as a manually overcome spring latching device, easier to manufacture and more user-friendly, however, is a construction in which the locking device comprises a backdrop and a locking member cooperating with it, of which one element with respect to the support and the other element with respect to the straight tube area can be fixedly attached is. The backdrop must then only be designed so that it allows all desired movements of the straight tube area. Although the link could be provided on the straight tube area and the locking member could be arranged stationary, there are manufacturing and assembly advantages if the link is provided on the guide and the locking member is firmly connected to the straight tube area.

So that a guide with a large one for the vertically displaceable and possibly also rotatable straight tube area Guide length is available, it is recommended to design the construction so that the guide has a guide tube that can be attached to the carrier. This can then be provided at its upper end with an annular collar which can be placed against the carrier from above, in order in this way to determine the axial position of the guide tube in a simple manner. If the guide tube is provided under the ring collar with an external thread for a nut that can be tightened against the carrier from below, the guide tube can also be particularly easily secured against displacement upwards. Although the above-mentioned and against the outer circumference of the straight pipe section z. B. could also be arranged at the edge of the carrier opening, it is advisable, in the presence of a guide tube provided with the said collar, to arrange the seal in this collar and to keep it secured against axial displacement. Then it is prevented that liquids or solid dirt can penetrate from above into the gap between the guide tube and the pipe area.

As already mentioned, any desired movement of the straight tube area and thus the water outlet opening can be made possible by appropriate design of the backdrop. For a pivoting of the water outlet opening and the vertical mobility of the straight pipe area or the actual water outlet device, however, a geometrically relatively simply designed and therefore easily and inexpensively producible backdrop is sufficient, which has the shape of a groove or a slot with an upper, approximately horizontally running first backdrop area, has an approximately vertically extending second link area and a lower, again approximately horizontally running third link area, the locking member being designed as a projection engaging in the link. Depending on the length of the approximately horizontal Scenery areas can then the actual water outlet device in its upper or in its lower position to z. B. pivot 90 ° or 180 °, and the length of the approximately vertical second backdrop area determines the stroke of the water outlet device. Although the backdrop z. B. can have the shape of a lying U, a simpler shape similar to a lying U is sufficient for all requirements.

So that when the water outlet opening is pivoted, the water outlet device in its upper position of use cannot be inadvertently brought into a pivoting position from which it can sink downwards, it is recommended to design the backdrop so that the upper, first backdrop area is one Hump forms, which must be run over with the projection cooperating with the backdrop by lifting and rotating the straight tube area before the projection can be brought into the vertical second backdrop area. In order not to unnecessarily limit the pivoting angle of the water outlet device determined by the length of the upper, first link area, the hump is expediently located at the transition from the first to the second link area.

For the manufacture, but also for the assembly of the water outlet device according to the invention, it is advantageous if the straight tube area is in several parts and is formed by a straight lower tube and an upper tube that is detachably connected, in particular screwed, to it.

The actual water outlet device projects the least above the level of the upper side of the support when it can be moved in an approximately vertical direction guided straight pipe section above an approximately horizontally extending pipe section connects, even if in the place of the latter z. B. could occur a slightly bent pipe area. The straight tube area and the approximately horizontally extending tube area could meet at a particularly right angle, but it is easier for production if there is a tube bend with a relatively small radius of curvature between the straight tube area and the horizontal tube area, since then the two Have pipe sections easily produced from a single piece of pipe by bending and z. B. welding work can be avoided.

As already indicated above, one or two control elements (one for a cold water valve and one for a hot water valve) could be integrated in the straight tube region or the approximately horizontally extending tube region; such a control element could, for. B. have the shape of a rotatable around the tube axis ring, which is provided with a corrugation, one or more bumps or the like in order to rotate the ring easily and thus to open and close the associated valve. However, a so-called hose shower is often desired for water outlet devices of the type in question; then the device according to the invention is expediently designed such that a mouthpiece provided with the water outlet opening and connected to a flexible hose is inserted into the free end of the horizontal tube region, and in this case the control element is expediently not in the straight tube region or in the horizontal one Integrate pipe area or into the mouthpiece.

In particular, if, for reasons of cost-effective production, the backdrop is designed as a slot machined into the guide tube, an embodiment of the device according to the invention is recommended in which a protective and stiffening tube is attached to the guide tube, which not only prevents dirt from penetrating from the outside prevented in the backdrop, but also improved the qualities of the guide for the vertically displaceable, straight pipe area and excludes that the actual water outlet device can be moved back and forth in its upper position of use. So that the guide tube and the protective and stiffening tube do not have to be manufactured very precisely with narrow tolerances, a further improvement is achieved in that at least two elastic snap ring-like ring elements are arranged at an axial distance from one another between the guide tube and the protective tube, each of which is from Protective tube is pressed against the guide tube in the radial direction. Such a ring element is then expediently arranged at least above and below the backdrop, even better at the upper and lower ends of the protective tube, in order to seal the gap between the two tubes at its upper and lower ends.

If the operating element is not integrated into one of the parts of the actual water outlet device that can be raised and lowered, embodiments are preferred in which the operating element is part of a valve unit that can be mounted separately from the vertically displaceable parts in a horizontal, plate-like carrier, with this carrier can be the same on which the parts that can be raised and lowered are provided, or another carrier, for example a cover plate receiving a built-in sink or - which is preferred - um a second battery bank of the built-in sink. For the installation of the valve unit in a built-in sink, the valve unit according to the invention can easily be designed so that it can be inserted into a standardized, circular fitting installation opening of built-in sinks, which has a diameter of 35 mm, preferably from below and then fastened.

• ein ungefähr topfförmiges Gehäuse mit einem Kragen zum Durchgreifen einer Öffnung in dem der Ventileinheit zugeordneten Träger sowie einer nach oben weisenden Abstützschulter, welche den Fuß des Kragens umgibt;
• eine im Gehäuse angeordnete Mischventilpatrone bzw. -kartusche mit einem nach oben vorstehenden und in den Kragen hineinragenden kipp- und drehbaren Steuerzapfen;
• eine auf ein Außengewinde des Kragens aufschraubbare und gegen die Oberseite des genannten Trägers festziehbare Mutter, sowie
• einen auswechselbaren, den Kragen umfassenden und auf der Abstützschulter aufliegenden Distanzring zum Einspannen des genannten Trägers zwischen der Mutter und dem Distanzring.

For embodiments with a valve unit arranged separately from the lowerable parts of the water outlet device and provided with the operating element, it is recommended to design the latter in such a way that it comprises

• an approximately pot-shaped housing with a collar for gripping through an opening in the carrier assigned to the valve unit and an upwardly pointing support shoulder which surrounds the base of the collar;
• a mixing valve cartridge or cartridge arranged in the housing with an upwardly projecting and pivoting control pin projecting into the collar;
• a nut which can be screwed onto an external thread of the collar and tightened against the upper side of said carrier, and
• an interchangeable spacer ring which surrounds the collar and rests on the support shoulder for clamping said carrier between the nut and the spacer ring.

In this way it can be ensured by choosing a spacer ring of appropriate thickness (dimension in the direction perpendicular to the plate-like carrier) that all over the Carrier protruding areas of the valve unit regardless of the thickness of the plate-like carrier always protrude equally far above the top thereof, without any other changes to the valve unit - in this connection it must be borne in mind that the thickness (plate thickness) z. B. a built-in stainless steel sink only a fraction of the thickness of a z. B. is cast or pressed plastic built-in sink.

The advantage that the collar and control pin of the valve unit then always protrude by a predetermined amount above the top of the carrier gains particular importance if the operating element is provided with a cap that overlaps the nut (or possibly the collar), because only then is it ensured that can tilt this cap in the same way as the control pin to fully open the valve unit. It is easiest for the cap to overlap the nut or possibly the collar as much as possible in order to prevent liquids and other dirt from entering the valve unit from above as far as possible, but without impeding or limiting the tilting movement of the control pin that in constructions in which the control pin can be tilted from a rest position in which the mixing valve cartridge is closed and the control pin extends approximately vertically into an inclined position in which the mixing valve cartridge is fully open, the cap is designed such that a the nut or collar-encompassing circumferential region of the cap is shorter on the side assigned to the inclination (measured in the direction of the control pin axis) than on the opposite side, and is so short that the cap does not limit the tilting movement of the control pin.

Figure 10B

10A is a sectional view corresponding to FIG. 10A, but the operating element assumes a position in which the mixing valve cartridge is fully open.

Fig. 1 shows a carrier plate 10, in a section along a vertical plane, which lies in front of the water outlet device according to the invention, so that an opening penetrated by the latter in the form of a circular hole in the carrier plate is not recognizable. In this opening, a guide tube 12 is inserted from above, which has an annular collar 14 at its upper end, the outer diameter of which is larger than the opening in the carrier plate 10 and which rests on the latter. Below the collar 14, the guide tube 12 has an external thread 16 onto which a fastening nut 18 is screwed, with the aid of which the carrier plate 10 can be clamped between the collar 14 and the fastening nut 18. A protective tube 20 is pushed onto the guide tube 12 from below and held in a manner to be explained later.

One along a vertical, i.e. H. Pipe axis 22 extending perpendicular to the support plate 10 is displaceable in the guide tube 12 and has a water outlet crane 24 which is held pivotably about this axis, as far as this can be seen in FIG a horizontal pipe section 32, in the right end of which is inserted according to FIG. 1, a mouthpiece 36 provided with a downwardly directed water outlet opening 34, so that it can be pulled out of the pipe section 32 according to FIG. 1 to the right. This mouthpiece 36 forms a hose shower, and the shower jet formed by the escaping water was designated 40.

1 shows the water discharge crane 24 in its upper position of use, in FIG. 2 it assumes its lower position, in which the vertical pipe section 28 is complete is inserted into the guide tube 12, but a lower tube 44, which will be described later and which is attached to the lower end of the vertical tube section 28, protrudes downward from the protective tube 20.

FIGS. 3 and 4 show that the vertical pipe section 28 of the upper pipe 26 is connected to the lower pipe 44 by means of a screw connection 46 and, like a straight pipe section 48, which is formed by the lower pipe 44 together with the vertical pipe section 28, in Guide tube 12 is guided and held, namely so that the unit formed by the two tubes 26 and 44 is displaceable in the direction of the tube axis 22 and rotatable about this axis - in cross section, both the inner contour of the guide tube 12 and the outer contour of the straight tube area 48 circular. In an inner annular groove of the collar 14, an elastic sealing ring 50 is arranged, which bears against the outer circumference of the straight tube section 48 under slight prestress and not only seals the annular gap between the guide tube 12 and the straight tube section 48, but also leads to the fact that the two Tubes 26 and 44 unit formed from their upper, in the use position shown in Figures 1 and 3 can not fall freely into their lower position shown in Figures 2 and 4, but slowly slides down when this unit in its upper position of use is released is and a locking device to be described later is ineffective.

On the outer circumference of the guide tube 12, an upper annular groove 52 and a lower annular groove 54 are provided at an axial distance from one another, between which there is a link 56, which is part of the locking device mentioned and the shape has a slot machined into the guide tube 12, the course of which will be explained later. With this backdrop, a projection provided on the lower tube 44 interacts, which is a grub screw 58 which engages in this slot and which is screwed into a threaded bore 60 of the lower tube 44 and is flush with the outer circumference of the guide tube 12.

The mouthpiece 36 shown in more detail in FIG. 5 has an end region 62 that is stepped on its outer circumference and left according to FIG. 5 with a circular cylindrical ring surface 64 and an external thread 66; 5 shows, the diameter of the ring surface 64 is smaller than the outer diameter of the mouthpiece 36 to the right of the end region 62, and the external thread 66 has an outer diameter which in turn is smaller than the diameter of the ring surface 64. The end region 62 is in that 1 to 4 right end of the horizontal pipe section 32 insertable; for this purpose the latter has a circular cylindrical fit 68, the inside diameter of which corresponds to the outside diameter of the ring surface 64. A flexible hose (not shown) is screwed onto the external thread 66, which runs through the upper pipe 26 and the lower pipe 44 and via which tap water can be supplied to the mouthpiece 36, be it cold water or hot water or mixed water at the desired temperature. This then flows into an inner channel 70 of the mouthpiece 36, in the water outlet opening 34 z. B. a conventional sieve insert can be screwed in.

As can be seen in FIG. 6, the slot forming the link 56 in the guide tube 12 consists of an upper, horizontally running first slot area 56a, a vertically running second slot area 56b and a lower one, likewise horizontally running third slot area 56c, which together form a backdrop with the shape of a lying U. At the transition of the upper horizontal slot area 56a into the vertically running second slot area 56b, the horizontal upper slot area 56a forms a hump 56d, the slot forming the link 56, however, everywhere having a slot width that is the same or slightly larger than the outer diameter of the grub screw 58 The upper horizontal slot area 56a (including bumps 56d) and the lower horizontal slot area 56c each extend over a circumferential angle of the guide tube 12, which is freely selectable and can be, for example, a little more than 90 ° or a little more than 180 ° around the water discharge crane 24 (taking into account the diameter of the grub screw 58) about the pipe axis 22 by 90 ° or 180 ° (the left ends of the two slot areas 56a and 56c according to FIG. 6 cannot be seen in the drawing).

Fig. 7 with a longitudinal section through the guide tube 12 serves only the purpose of showing that in the wall of the guide tube in the region of the annular grooves 52 and 54, several elongated holes 52a and 54a are provided, which are spaced apart over the circumference of the guide tube 12 are arranged and the purpose of which will be explained below.

FIG. 8 shows the protective tube 20 shown in FIGS. 1 and 2 in a longitudinal section.

In each of the two ring grooves 52 and 54, a snap ring-like ring element 74 shown in FIGS. 9A and 9B made of an elastic material can be inserted; this has three projections 74a on its inner circumference, which then engage in the elongated holes 52a and 54a and prevent the ring elements 74 from rotating relative to the guide tube 12. The diameter of the base of the annular groove 52 or 54, the inner diameter of the protective tube 20, the outer diameter of the ring elements 74 and their inner diameter between the projections 74a are now coordinated with one another such that after the protective tube 20 has been passed over the guide tube 12 and the two ring elements 74 has been pushed, the protective tube 20 presses the guide tube 12 in the radial direction via the ring elements 74; in addition, the lower ring element 74 prevents dirt from penetrating from below into the annular gap between the protective tube 20 and the guide tube 12 and thus into the area of the link 56. For this purpose, the ring elements 74 are fastened to the guide tube 12 in such a way that their gaps 74b - as seen in the direction of the tube axis 22 - do not lie in the region of the link 56. The length of the protective tube 20 must therefore correspond at least to the axial distance between the two annular grooves 52 and 54 and is preferably somewhat larger than this distance.

As can be seen from FIGS. 3 and 4 in connection with FIG. 6, the water outlet crane 24 is always locked in its upper use position or in its lower position when the grub screw 58 is in the upper slot area 56a on the left (according to FIG. 6) from the bump 56d or in the lower slot area 56c to the left of the vertical slot area 56b. When the water discharge crane 24 is in its upper use position, the grub screw 58 can be lifted over the hump 56d and brought over the vertical slot area 56b either by slightly lifting and slightly pivoting the water discharge crane 24, thanks to the rounded flank of the hump, as shown in FIG. 6 56d the latter can also be overcome simply by pivoting the water discharge crane 24, because the left flank of the hump 56d automatically leads to the water discharge crane being raised slightly.

FIGS. 10A and 10B show a carrier plate 10 ', which can be the carrier plate 10 shown in FIGS. 1 and 2, but also another carrier plate. The carrier plate 10 'also has a particularly circular opening 100, in which a valve unit, designated as a whole by 102, is fastened. This comprises a pot-shaped housing 104, a commercially available mixing valve cartridge 106 accommodated by the latter with a control pin 108 for actuating the mixing valve cartridge, a nut 110 and an operating element 112 with a handle 114 for actuating the valve unit 102. The housing 104 has a housing lower part 104a and an upper housing part 104b, which are connected to one another via a screw connection 104c after the mixing valve cartridge 106 has been inserted into the lower housing part. The upper housing part 104b has a collar 104d which extends through the opening 104 and to which the nut 110 can be fastened by means of a screw connection 104e. Below the screw connection 104e, the collar 104d has an outer diameter which corresponds to the diameter of the opening 100, so that the valve unit 102 in the support plate 10 'cannot move under any circumstances, and thus the upper housing part 104b can be inserted into the opening 100 from below the outer diameter of the collar 104d in the area of the screw connection 104e is in no case greater than the diameter of this opening. So that the parts of the valve unit 102 protruding upward above the upper side of the carrier plate 10 ', regardless of the thickness of the carrier plate 10', always protrude upwards over the same, sits on one formed by the upper housing part 104b Support shoulder 104f an exchangeable spacer ring 116, between which and the nut 110, the carrier plate 10 'is clamped after the nut has been tightened. By using a spacer ring 116 of corresponding thickness - measured in the direction perpendicular to the plane defined by the carrier plate 10 '- the thickness of the carrier plate 10' can thus be taken into account (in the case of a thicker carrier plate, a less thick spacer ring 120 is used and vice versa), so that by choosing an appropriate spacer ring, it can be ensured that the valve unit 102 always protrudes equally far up over the top of the carrier plate 10 '.

Mixing valve cartridges of the type in question can be operated in the following way: By tilting the control pin 108 from its vertical position shown in FIG. 10A to the oblique position shown in FIG. 10B, the mixing valve cartridge can be fully opened during the tilting movement - in the vertical direction The position of the control pin is completely closed, and any mixing ratio between cold water and hot water can be set by rotating the control pin 108 about its pin axis 108a. In order to be able to effect these movements of the control pin 108, but on the other hand to prevent liquids and dirt from penetrating from above into the opening formed by the ring nut 110 and the collar 104d, the operating element 112 fastened to the control pin 108 by means of suitable screw means forms a cap 120 whose peripheral area forms a cap jacket 122 with a bevelled lower edge 124. The beveling of this lower edge means that the operating element 112 can be brought into the tilted position shown in FIG. 10B, because the lower edge region 124a on the side assigned to the inclined position is in the closed position shown in FIG. 10A the mixing valve cartridge 106 is at a greater distance from the carrier plate 10 'than the opposite lower edge region 124b. At the same time, however, the cap 120 overlaps the nut 110 in all positions of the operating element 112 to such an extent that in practice liquids, dirt and the like cannot get into the opening of the valve unit 102 formed by the nut 110 and the collar 104d.

After the attached drawing in connection with the above description of the illustrated embodiment makes the latter understandable in all details, the alternative embodiments of the device according to the invention described below will be readily understood by the person skilled in the art even without their graphic representation.

In the embodiment shown in the drawing, the backdrop 56 has an approximately C-shaped shape; So that one and the same water outlet device can be combined, for example, with built-in sinks, some of which have a sink to the right of the mounting point for the water outlet device and the others to the left of this point, the tube area corresponding to the straight tube area 48 of a modified embodiment should not only be around 90 °, but can be swiveled by approximately 180 °, it would be advantageous if this tube area could be lowered in both swivel end positions. This can be achieved in a simple manner in that the backdrop - of course in a developed form - has approximately the shape of a rectangle.
