Abstract

The invention relates to a device for actuating water fittings. Of particular importance is, first of all, the kinematic arrangement which converts the pivoting movements of the water outlet about two axes into a rotation and a displacement of the flat control surfaces of the parts relative to one another. According to the invention, it is proposed for this purpose to connect a transmission part positively or permanently to both pivoting movements of the water outlet but also to couple it to at least one of the parts. Also of importance is the fact that the water outlet is connected permanently or positively, via a connecting piece, to a sealing surface of approximately hemispherical form which is surrounded by a guide housing, the connecting piece being pivotable about the pivoting axis in a slot in the guide housing. Also important is the fact that at least one driver with a clearance angle is arranged between the water outlet and the displaceable parts.

Device for actuating water fittings In the main application P 35 10 930.0 of 03/26/1985 describes devices that allow simple actuation of water fittings, especially mixer fittings, by swiveling the water outlet around one or two axes.

The present additional application extends the explanations described, by including the extremely reliable and preferred ceramic discs as Rule elements, which are protected in the context of the previous patent deregistration, but Was not mentioned and described in detail. Mainly are in the present Patent application reveals new, additional inventive ideas, as further Design of the original application are of great importance.

The kinematic arrangement is of particular importance, the pivoting movements of the water outlet (5) around two axes, in one rotation and a displacement of the planar ruled surfaces of the parts (40 and 41) relative to one another converts. According to the invention, a transmission part (39) is proposed for this purpose in a form-fitting manner or to be firmly connected to both swivel movements of the water outlet (5), but also to be coupled to at least one of the parts (40) and / or (41).

Since the movements on the one hand in space around two axes, on the other hand run in the plane as displacement and / or rotation is suggested with the transmission part (39) to use a universal joint (43), the two on top of each other vertical axes can be rotated at will.

This is at least the conversion of a spatial pivoting movement in a rotary movement in the plane of the ruled surfaces of the parts (40 and 41) possible.

In addition, one of the axes of the universal joint is proposed (43) parallel e.g. to the pivot axis (42), which determines the amount of water flowing out to be arranged, but not coinciding with this one, but with a specific one Center distance, which acts as a lever arm for moving the parts (40 and 41) to one another serves.

The storage of an approximately hemispherical sealing surface is advantageous (47) in a guide housing (45) which has a slot (48) from which a connecting piece (46) protrudes, which establishes the connection to the water outlet (5). The water outlet (5) is fixed or form-fitting over the connecting piece (46) with the sealing surface (47) and can be pivoted with these parts about the pivot axis (42).

To prevent dirt and debris from entering the slot (48) To prevent, but also for design reasons, it is advisable to completely open the slot (48), or at least partially to be closed with a cover (52) In the main application is recommended as a preferred arrangement by swiveling the water spout (5) The mixing temperature around an approximately vertical axis, i.e. the mixing ratio of To change cold and hot water, so that e.g. a position of the water outlet (5) corresponds to "cold" on the left and "hot" on the right.

The arrangement of a clearance angle (50), which is determined by drivers (49) after which rotation the actual regulation begins, allowed after Choice of the desired mixing temperature, the water outlet (5) e.g. in the most preferred Bringing the "middle position" without changing the previous setting. A change the mixing temperature is still set by briefly swiveling - "tapping" - the water outlet (5) possible to the left or right.

The installation of a traversable spring catch (51) in the area of the Pivoting angle (44), which determines the amount of water running out, is new and of great importance Importance, because it marks e.g. a "savings position" can be, in which only half the amount of water runs out. This possibility comes under the The necessary water and energy saving is of great importance. If you want one A larger amount of water is pressed a little harder and the "economy position" is passed over.

For the structural design of a water fitting according to the invention are two characteristics of particular importance as they are the dimensions and therefore the Significantly favor the simplicity of the structure.

First of all, it is possible to remove at least part of the universal joint (43) to be arranged within the hemispherical sealing surface (47). This results in a compact accommodation of the individual parts but also a protected and space-saving, that means a cost-saving solution.

The second major improvement to the overall structure is therein the main axis (53) of the water fitting is not vertical, but a little oblique placed to be arranged, namely about half the pivot angle (44) of the water outlet (5). This means first of all that the connecting piece (46) is in an end position (fully turned up) is approximately vertical and thus the temperature setting is convenient in this position can be made by pivoting about this - now also vertical - axis.

The inclination of the main axis (53) by half the swivel angle (44) but also has the effect that the slot (48) in the guide housing (45) is symmetrical, which favors the accommodation of all parts in the interior. moreover sees this inclination is very advantageous.

Fig. 1 shows an example, schematic sketch of a water fitting to explain the invention. The sketch is in no way restrictive with regard to this the execution, both the entire valve or parts of it can be according to the state the technology can be varied. As far as the function of the parts is the same as the main application the same reference numbers have been entered.

In Fig. 1, the valve body (1) as a cylindrical tube, which expires in a spherical guide housing (45). The cold and Hot water supply lines (2 and 3) overlap in Fig. 1, since they are one behind the other lie. The water outlet (5) is via a connecting piece (46) with the approximately hemispherical Sealing surface (47) connected in a form-fitting manner. The guide housing (45) has a slot (48) in which the connecting piece (46) has a pivoting movement can run around the pivot axis (42). The O-ring (70) seals elastically.

A wall (54) is provided in the hemispherical sealing surface (47), which engages around the displacement axis (60) of the universal joint (43).

The fork (57), the transmission part, is located in the cardan slot (56) (39). The fork (57) transmits all shifting and rotating movements of the universal joint (43) on the displaceable part (40). The part (41) is firmly in the holder (58) used. The holder (58) is pushed into the valve body (1) and is e.g. fixed by a screw ring (59). The O-ring (55) ensures a seal the bracket (58).

In Fig. 1, the open state of the valve is shown. In this In this case, the opening (61) in the fixed part (41) is aligned with the opening (62) in the sliding part Part (40). The water can e.g. from the supply line (2) through the openings (61), (60) and (62) in the transmission part (39) flow into the mixing space (64) and to both Sides of the wall (54) into the bore (65) of the connecting piece (46) and finally get into the water outlet (5). The O-rings (69) are important for sealing.

In Fig. 2, the valve is shown in the closed state. Of the The water outlet (5) is swiveled up and with it the connecting piece (46) which Sealing surface (47) and the wall (54). The displacement axis (60) and with it the Fork (57) with transmission part (39) and the displaceable part (40) are opposite the part (41) offset and the openings (61) and (62) are no longer aligned. Of the Water flow is closed.

The various control positions are schematically shown in FIGS. 3 to 6 the sliding parts (40) and (41) shown. To simplify the illustration are the openings (61) and (62) drawn as narrow rectangles. The openings (61 and 62) are for cold water and the openings (66 and 67) are for hot water.

Fig. 3 shows both passages open, thus lukewarm water.

Fig. 4 shows both passages closed, thus no flow.

Fig. 5 shows only the openings (61 and 62) in alignment, thus cold Water.

Fig. 6 shows only the openings (66 and 67) in alignment, thus warm Water.

The intermediate positions then correspond to the different amounts of water or the different mixing temperatures. By other shapes and positions of the openings (61 and 62) or (66 and 67), extensive optimization and adaptation is possible, as already implemented in numerous applications of ceramic disks.

In Fig. 1 and 2, the arrangement of a cover (52) is schematically shown to protect the slot (48) against contamination and foreign bodies.

In this example, the cover (52) is directly part of the water outlet (5), but it could also be designed as an intermediate piece, e.g. on the Connecting piece (46) is pushed.

The attachment of such a cover is simplified by the fact that the external shape of the fitting is a spherical surface and and therefore the cover can follow all pivoting and rotating movements.

In Fig. 1 and 2, the arrangement of a clearance angle (50) is between the water outlet (5) and the connector shown as an embodiment. The sectional drawing Fig. La shows the water outlet (5) with an inserted connector (46), which has a segment groove (68) in which the carrier (49) provided as a driver (49) The screw can be freely rotated with a clearance angle (50) before it is positively locked Connecting piece (46) takes with it.

In Fig. 2 the arrangement of a spring catch (51) is shown schematically, which is free in the area of the slot (48), but before reaching the end position the edge of the slot (48) runs up. Depending on the strength of the spring (69) you can Set the force that is necessary to override the detent. This "savings position" is new and much appreciated. This example is also to be understood only schematically and many other useful solutions are possible.

Also in Figs. 1 and 2 are the advantages of inclination of the major axis (53) can be clearly seen around half the pivoting angle (44). First of all, in Fig. 1 when the setting is fully open, the axis of the connecting piece (46) is approximately vertical and the water outlet is pivoted in an approximately horizontal plane, which is essential contributes to ease of use.

All inner parts are symmetrical to the main axis (53), in particular the slot (48), which also determines the position of the cover (52) and the O-ring (70). A host of other advantages are direct to the illustrated embodiments refer to.
