Description

The invention relates to a sanitary water line fitting comprising a cartridge for controlling at least the amount of outflowing water, wherein the cartridge as Umschaltkartusche to release the Wasserausflusses established via different waterways and switching by rotation of a control pin of the cartridge, starting from a water outlet blocking zero position in the respective , Direction associated with a waterway direction and is placed on the control pin so that a rotatably coupled rotatable operating handle for the cartridge setting.

A sanitary water pipe fitting of the aforementioned type is known by use, in particular in the context of bathtub fittings, which have a water outlet for filling the bathtub and a shower outlet connected to a shower outlet as waterways, with a switchover between these waterways is provided. This switching is set up in known fittings in the form of a so-called Umschaltkartusche. Starting from a the water outflow blocking Zero position is released by rotation of a control pin of the cartridge in one or the other direction of rotation of the water outlet either to the bath spout or shower, wherein in each of the zero position of the cartridge outgoing direction of flow of the guided over the respective controlled water outlet water outflow is established.

In such a water line fitting, the problem arises that the water outlet blocking the zero position of the cartridge in some cartridge types can only be identified by the stopping water outflow, which is a corresponding limitation of the operating convenience.

A generic fitting is in US2009 / 0265848 disclosed.

The invention is therefore based on the object, a sanitary water supply fitting with the aforementioned generic features set up so that the zero position of the cartridge and thus the starting position of the operating handle is made recognizable.

The solution to this problem arises, including advantageous refinements and developments of the invention from the content of the claims, which are adjusted to this description.

The invention provides in its basic idea that between the cartridge and the operating handle a stop piece with at least one aligned parallel to the control pin of the cartridge, axially to the operating handle protruding and inwardly resiliently formed stop pin is interposed, at the the stop piece outside embracing inner contour of the operating handle a in the zero position of the control pin of the cartridge corresponding gripping position is associated with the stop pin receiving detent recess.

The invention has the advantage that the starting position of the operating handle according to the zero position of the cartridge is now felt by the engagement of the stop pin in the locking recesses of the operating handle. Upon rotation of the operating handle over the corresponding detent position away, the engagement of the at least one stop pin in the associated detent recess increases the resistance to further rotation of the operating handle. This snapping is also audible to the user or can be made audible by an appropriate choice of materials, so that further support the identification of the zero position of the cartridge is given. However, the corresponding latching resistance is not so large that the rotation of the operating handle out of the detent position or beyond is made difficult in an uncomfortable way, so that the ease of use is not limited.

According to one embodiment of the invention can be provided that are arranged in a symmetrical arrangement on the stop piece two opposing stop pins and on the operating handle according to two locking recesses.

Advantageously, it can be provided that on the outer circumference of the stop piece extending in the circumferential direction guide surface is formed for the current during its rotary movement operating handle.

In the known water line fittings, a so-called ECO function is further realized in the control of the leading water to the shower, in which the shower water supplied amount is determined by a correspondingly limited rotational position of the operating handle with stop position, which in addition by operation of the operating handle provided stop button this stop position of the operating handle over-turned and thus the amount of water for the shower can be further increased. According to one embodiment of the invention, it is provided to use the guide surface formed on the stop piece for the formation of this ECO function by providing that on a wegerstreckenden from the stop pin portion of the guide surface a radial projection with a stop surface for a in the operating handle resiliently arranged stop button is formed such that the further rotation of the operating handle is excluded in befindlicher in the rest position stop button by the stop surface of the survey.

This can be provided according to an embodiment of the invention that the stop button in the operating handle against spring action can be brought into a position in which the stop button overruns the survey of the stop piece and releases a further rotation of the operating handle against the stop piece.

In order to enable after the rotation of the operating handle in its end position with fully available amount of water a reverse rotation of the operating handle to the zero position, according to an embodiment of the invention, that the stop surface in the circumferential direction of the stop piece opposite surface than in the reverse rotation of the operating handle becomes effective and a run-over of the survey by the stop button enabling start bevel is formed.

The design of a water line fitting can be simplified according to an embodiment in that an attachable to the stop piece handle adapter is provided as a carrier of the associated operating handle and the at least one detent recess is formed on the inside of the handle adapter.

In the FIG. 1 illustrated tub filling battery has a cast body 10, on which in the FIG. 1 the left end of an adjustment handle 11 is arranged for the temperature selection, by means of which a arranged in the cast body 10, not shown thermostat for controlling the mixing temperature of the water is controlled. On the opposite, in FIG. 1 right side of the cast body 10, a switching cartridge 12 is provided, which in itself the functions of switching between a tub outlet 40 and a shower connection, not shown on the one hand and a quantity control for each of the two controllable waterways on the other hand, as known in the art. The switching cartridge 12 has a zero position, from which either the tub outlet 40 or the shower connection, not shown, can be controlled by turning a control pin 20 formed on the switching cartridge 12 into the two directions of rotation that are opposite from the zero position.

The switching cartridge 12 can be mounted on the cast body 10 by means of a retaining ring 13 which can be screwed to the cast body 10. On the Umschaltkartusche 12 is first a stop piece 14 can be plugged, which cooperates with a handle adapter 15 as a carrier of an operating handle 16, as will be described in detail below. The operating handle 16 can be connected to the handle adapter 15 by means of a fastening screw 18, the screw opening being to be concealed by means of a handle panel 17 to be fixed to the operating handle 16. At the operating handle 16, a stop button 19 is further arranged, as will be described below.

The aforementioned components are also out FIG. 2 more clearly and will be described below with reference to the FIGS. 3 to 7 described in detail.

As is clear from the FIGS. 3 and 4 results, the stopper 14 is first mounted on the Umschaltkartusche 12. This stop member 14 has diametrically opposed stop pins 22 which extend in a direction parallel to the control pin 20 of the Umschaltkartusche 12 arrangement of the stopper piece 14 towards the handle adapter 15 away; the stop pins 22 are designed so that they can spring radially inward. On: its circumference, the stop piece 14 has a guide surface 23 for the operating handle 16, wherein at a portion of this guide surface 23 a radially-upwardly rising Survey 24 is formed with a circumferentially oriented stop surface 25 and a circumferentially adjoining run-on slope 26. The guide surface 23 is limited in the circumferential direction in each case by end stops 27 for the rotation of the operating handle 16 relative to the stop piece 14.

As it turned out FIG. 3 shows, the control pin 20 of the switching cartridge 12 is rotated in the direction of the arrow 41 for mounting the water line fitting, so that in this position the adjustable over the Umschaltkartusche 12 waterway to the bath inlet 40 is fully open. In this position, the Umschaltkartusche 12, the stopper piece 14 is placed on the hexagon 21 of the Umschaltkartusche 12 such that the mounted on the stop piece 14 mounting mark 28 faces upwards such that the stop pins 22 of the stop piece 14 are aligned in the horizontal. The connection between the abutment piece 14 and the Umschaltkartusche 12 is made by a positive connection by engagement of the hexagon 21 of the Umschaltkartusche 12 in a correspondingly provided design of the stop piece 14.

How to continue first off FIG. 5 results, is in the out FIG. 3 resulting mounting position of Umschaltkartusche 12 and stop piece 14 below the handle adapter 15 by attaching the handle adapter 15 to the control pin 20 of the Umschaltkartusche 12 as well as mounted on the stop piece 14 projecting stop pin 22. This assembly takes place in such a way that a correspondingly provided on the handle adapter 15 mounting mark 29 is in accordance with the mounting mark 28 of the stop member 14.

As complementary FIG. 6 results are at the inner, with the stopper piece 14 engaging circumferential surface of the handle adapter 15 corresponding to each other locking recesses 31 are formed, which for locking with the projecting from the stop piece 14 stop pin 22 are set up. The otherwise sleeve-shaped handle adapter 15 is stiffened in its interior by stiffening ribs 30 which support a sleeve 33 for receiving the control pin 20 of the switching cartridge 12. At the end of the control pin 20 of the Umschaltkartusche 12 and inside the sleeve 33 of the handle adapter 15 each have a knurling 34 is formed so that when attached to the control pin 20 handle adapter 15 a rotationally fixed connection between the handle adapter 15 and the control pin 20 of the Umschaltkartusche 12 is given.

With regard to the mounting of the handle adapter 15 to the Umschaltkartusche 12 with stop piece 14 arranged thereon, it should also be noted that starting from the FIG. 5 following assembly position with the fully opened waterway to the water outlet 40 after attaching the handle adapter 15 to the control pin 20 of the Umschaltkartusche 12 a rotation of the handle adapter 15 by 90 ° counterclockwise in the direction of the zero position of the Umschaltkartusche 12 make, in the order of 90 ° twisted position = zero position the stop pin 22 of the stop piece 14 clearly felt and audibly engage in the locking recesses 31 of the handle adapter 15 so that the off FIG. 7 resulting assembly position of the handle adapter 15 sets, which corresponds to the zero position of the switching cartridge 12.

As this is not further shown, however, results from a synopsis of the drawing figures, the operating handle 16 is slid against it with spring action pivotally arranged stop button 19 on the handle adapter 15 and fixed by means of the fastening screw 18 thereto. The dimensions of stopper 14, handle adapter 15 and operating handle 16 with stop button 19 are coordinated so that the operating handle 16, the handle adapter 15 engages and runs in its rotation together with the handle adapter 15 relative to the fixed stop member 14 on the guide surface 23, wherein the arranged on the operating handle 16 stop button 19 with the in the guide surface 23 of the stop piece 14 arranged survey 24 cooperates.

As far as with reference to FIG. 3 It was noted that a rotation of the control pin 20 of the switching cartridge 12 in the clockwise direction (arrow 41) causes the flow control for the tub outlet, results in accordance with a rotation of the operating handle 16 with handle adapter 15 counterclockwise a flow control for the water supply to the shower. In this, starting from the zero position of the Umschaltkartusche 12 counterclockwise extending portion of the guide surface 23 of the stop piece 14, the survey 24 is arranged with the zeroing stop surface 25 so that upon rotation of the operating handle 16 with stop button 19 befindlicher located on the stop button 19 , radially inwardly projecting projection on the stop surface 25 of the survey 24 abuts. In this position, the amount of water supplied to the shower head is limited and can only be increased by turning the operating handle 16 over the elevation 24 until the end stop 27 formed on the stop piece 14 has been reached with full opening of the waterway. This overrun of the elevation 24 is possible because the stop button 19 is pressed against the operating handle 16 so that the protrusion formed on the stop button 19 lifts over the stop surface 25, so that the further rotation of the operating handle 16 is made possible. When turning back the operating handle 16 in the zero position of the Umschaltkartusche 12, the run-on slope 26 of the survey 24, the stop button 19 automatically over the survey 24, so that the reverse rotation of the operating handle 16 is not hindered in the zero position of the changeover cartridge 12.
