Description

[0001] The present invention relates to a frost-proof outlet fitting and an outlet housing of a fitting.

[0002] A frost-proof outlet fitting according to the preamble features of claim 1 is known from DE 20 2023 102 110.

[0003] The object of the present invention is to provide a frost-proof outlet fitting that ensures reliably correct installation.

[0004] The object of the invention is achieved by a frost-proof outlet fitting with the features of independent claim 1. Further advantageous embodiments are specified in the dependent claims and the following description.

[0005] In the present context, the term "rosette pierced" by an intermediate pipe or outlet housing preferably means that the rosette at least partially surrounds the intermediate pipe or outlet housing. Preferably, the intermediate pipe or outlet housing extends at least partially through the rosette.

[0006] The intermediate spindle is typically positioned radially away from the surrounding housing components, i.e., the intermediate tube and the housing walls of the outlet housing. A continuous annular space is usually provided, extending substantially along the entire length of the intermediate spindle. Only the free ends of the intermediate spindle, which are connected to the other parts of the outlet fitting, are typically radially clamped to connect to the spindle of the valve head on the outlet housing side or to the valve body in the area of ​​the valve housing.

[0007] This annular space serves as thermal insulation against the water-carrying inner section. The intermediate pipe typically extends beyond an exterior building wall and is directly connected to the outlet housing there. Thus, at least the section of the intermediate pipe facing the building wall is exposed to the prevailing temperature. In winter, this temperature can be significantly below 0 °C.

[0008] With regard to the necessary strength, the intermediate pipe can be made of plastic or metal. The intermediate pipe is screwed directly to the outlet housing. The intermediate pipe of the present invention also carries a rosette that projects beyond and thus covers the borehole in the building wall on the outside of the building.

[0009] The rosette of the present invention comprises at least a first rosette part and a second rosette part. The first rosette part primarily serves to cover the pipe penetration, while the second rosette part is designed for attachment to the outlet housing or the intermediate pipe.

[0010] The second rosette part is securely held in place, as it is attached to the outlet housing or the intermediate pipe. This attachment is preferably a threaded connection.

[0011] The first rosette part, however, is not attached to the outlet housing or the intermediate pipe in this manner. It is merely held in place by the second rosette part, and this holding by the second rosette part can occur in various ways. Thus, the first rosette part, which covers the pipe penetration, rests against the exterior wall of the building and is held in this position by the second rosette part.

[0012] In the prior art outlet fitting, the second rosette part is screwed against the first rosette part. To compensate for the angle of the outlet body or intermediate pipe passing through the building wall at an angle, the first and second rosette parts form curved contact areas that allow a certain degree of pivotability between them. In the solution according to the invention, the second rosette part has identically designed second contact areas on opposite end faces. As in the prior art, the second rosette part can be placed onto the intermediate pipe or outlet body and locked to it, for example, by screwing it on. Due to the identically designed contact areas, the second rosette part can be slid onto the associated pipe body that passes through the building wall, as is known in the art.However, during assembly, it is irrelevant which of the two end faces the second rosette part is placed against the first rosette part, because according to the invention, the second rosette part is identical in this respect.

[0013] For the purposes of this invention, the contact area is understood to be that part of the second rosette that, during assembly, is brought into contact with the first rosette and its first contact area. At least those surfaces on opposite end faces of the second rosette are considered identically designed second contact areas, provided they generally have the same convex curvature. The curvature in question is the convex curvature that is visible in a side view parallel to the central longitudinal axis or in a sectional view along the central longitudinal axis. It is essential that the contact areas have the same curvature in this view. It is not necessary for the second contact areas on opposite end faces of the second rosette to also be identical in the circumferential direction, although such a configuration is preferable.Further advantages, objectives, and features of the present invention are explained below with reference to exemplary embodiments, which are also illustrated in the accompanying drawing. The drawing shows: . Fig. 1 a longitudinal sectional view of a first embodiment of a frost-proof outlet fitting; Fig. 2 a schematic representation of a rosette not attached to the outer wall according to the state of the art; Fig. 3 a perspective view of a second embodiment of a frost-proof outlet fitting; Fig. 4 a schematic representation of a third embodiment of a frost-proof outlet fitting; Fig. 5 a perspective view of a rosette according to Fig. 1, Fig. 3 and Fig. 4; Fig. 6 a perspective view of a first rosette part according to Fig. 5; Fig. 7 a perspective view of a second rosette part according to Fig. 5 and Fig. 8 a side view of the second rosette part after Fig. 7.

[0014] In a first embodiment according to Fig. 1 comprises a frost-proof outlet fitting, a valve body 10, an outlet body 30, and an intermediate spindle 50 arranged between the two bodies 10 and 30, as known from EP 3 139 074 A1. The valve body 10 comprises a metallic valve seat body 12, which is essentially cylindrical and is projected at its outer circumference by a collar 14 with a polygonal cross-sectional shape. The valve seat body 12 is axially fixed in the inlet of an intermediate tube 80.

[0015] For this purpose, the intermediate tube 80, which surrounds the intermediate spindle 50, forms a single-piece widening 82 with a polygonal cross-sectional shape corresponding to the cross-sectional shape of the collar 14. The widening 82 forms an axial shoulder 84 at its inner end, against which the collar 14 abuts. On its front face, the collar 14 is fixed axially by locking means in the form of two pins 16, which are received in transverse bores 18 extending perpendicular to the longitudinal axis of the intermediate tube 80. The valve seat housing 12, thus axially fixed, is sealed against the intermediate tube 80 by means of two O-rings 20, which are inserted into grooves recessed at the inner end on the outer circumference of the valve seat housing 12.

[0016] The polygonal outer circumferential surface of the widening 82 forms a seat 83 onto which a mounting ring (not shown) with a polygonal bore can be slid. The mounting ring, the intermediate pipe 80, and the valve seat housing 12 are accordingly fixed to one another in a rotationally fixed manner and can be fixed to a building wall. The mounting ring has several mounting holes distributed around its circumference for installation on the building wall.

[0017] The valve seat housing 12 forms a valve seat 26 with an inner circumferential surface for the seating of a valve body 52. ​​The valve body 52 carries a seal 54 at its inlet end and is formed at its opposite end as a thin-walled cylinder, which forms a cylindrical receptacle for a pipe aerator cartridge 56 and an internal thread 58. This thread engages with a connecting sleeve 60, which is inserted at its end into the intermediate spindle 50 up to a collar 62 of the connecting sleeve 60 and is connected to the intermediate spindle 50 in a rotationally fixed and axially fixed manner, in particular by being pressed into it. The valve seat housing 12 is sealed against the valve body 52 by two sealing rings 55, which are held in grooves recessed in the valve body 52.Between these sealing rings 55 and the seal 54, several radially opening bores are provided on the valve body 52, forming inlets 57 that lead to the hollow intermediate spindle 50.

[0018] The outlet housing 30 has a valve head 32 with a guide sleeve 33, on which an adjusting spindle 34 is rotatably but axially fixed. This adjusting spindle 34 engages in thread with a hollow spindle 35, which is penetrated on one side by the adjusting spindle 34 and receives the intermediate spindle 50 at its end on the opposite side. The spindle 35 is sealed against the guide sleeve 33 on the side of a rotary handle 38, which is rotationally fixed to the adjusting spindle 34, by means of two O-rings 36, while being axially displaceable. On the opposite side, there is another O-ring 37, which seals the spindle 35 against an inner circumferential bore of the outlet housing 30.The spindle 35 features a clamping sleeve 39, which also serves as a centering element, acting as an end plug. This sleeve is held in the spindle 35 in threaded engagement, allowing axial displacement, and directs the flow through the spindle 35 towards the rotary handle 38. The clamping sleeve 39 includes a cylindrical segment 40, which is integrally mounted to the clamping sleeve 39 and provided with several radial bores 41. These bores align with several radial bores 42 recessed in the spindle 35, forming outlets 42. A cavity is provided between the bores 41 and 42 to allow the medium to flow through, enabling the medium to flow radially through the bores 41 and 42 even if they are not perfectly aligned.Approximately at the axial height of these bores 41, 42 there is an aerator 43 which, depending on the internal pressure, introduces air through the bores 41, 42 into the intermediate spindle 50 or is closed in the event of an overpressure of the fluid acting in the outlet housing 30, so that the fluid cannot escape through the aerator 43.

[0019] The outlet housing 30 is screwed to the outlet-side end of the intermediate pipe 80. The connection is made without sealant. A rosette 44, screwed to the intermediate pipe 80, is located approximately at the level of this connection point.

[0020] With this design, the fluid is guided through the outlet fitting, bypassing the annular space that is recessed between the intermediate spindle 50 and the intermediate tube 80. Instead, the fluid flows longitudinally through the fitting solely through the hollow interior of the intermediate spindle 50. The fluid enters the valve body 52 on the inlet side through the inlets 57, passes the non-return valve cartridge 56 and the connecting sleeve 60, flows through the hollow intermediate spindle 50, and exits radially through the radial bores 41 and the outlets 42.

[0021] At this height, the outlet housing 30 is extended by a hose fitting 45 for connecting a water hose, which is screwed into the metallic outlet housing 30 via an interposed pipe aerator 46. The outlet housing 30 has a ventilation bore 47 between the hose fitting 45 and the pipe aerator 46. In the event of backflow against the intended flow direction from a hose into the hose fitting 45, the pipe aerator 46 blocks the passage to the spindle 35, preventing the fluid from entering the intermediate spindle 50 and instead diverting it through the ventilation bore 47.

[0022] In the present embodiment, the rosette 44 comprises a first rosette part 130 for covering a pipe penetration 154 and a second rosette part 140. The second rosette part 140 is attached to the intermediate pipe 80 by being screwed together via a thread. The first rosette part 130 is held by the second rosette part 140.

[0023] A frost-proof outlet fitting is typically installed in a building of 150, as is the case in Fig. Figure 2 shows that an intermediate pipe 80, laid in a pipe penetration 154 of a building 150, is arranged with a slope so that the water can drain away outside the building. Thus, the intermediate pipe 80 is oriented at an angle to an outer wall 152, deviating from a perpendicular angle. A rosette 44, as known from the prior art and in the Fig. As shown in Figure 2, the rosette 44 is attached to the intermediate pipe 80 in such a way that, due to the slope of the intermediate pipe 80, it does not lie flush against the outer wall 152. Angular compensation is not possible with the rosette known from the prior art.

[0024] In a second embodiment according to Fig. The assembly comprises a rosette 44, which is attached to a spout housing 30, a first rosette part 130 for covering a pipe penetration 154, and a second rosette part 140 for attachment to the spout housing 30. The second rosette part 140 of the rosette 44 can be attached not only to the intermediate pipe 80 but also to the spout housing 30, as shown in the present embodiment. The second rosette part 140 is screwed to the spout housing 30 via a thread. The first rosette part 130 is held in place by the second rosette part 140.

[0025] In a third embodiment of a frost-proof outlet fitting according to Fig. In the present embodiment, an intermediate pipe 80 is installed in a pipe penetration 154 of a building 150. A rosette 44 is penetrated by the intermediate pipe 80. The rosette 44 has a first rosette part 130 for covering the pipe penetration 154 and a second rosette part 140. In the present embodiment, the second rosette part 140 is attached to the intermediate pipe 80. The first rosette part 130 is held by the second rosette part 140. The rosette 44 lies flush against an outer wall 152 of the building 150 and is connected to the intermediate pipe 80, which is oriented at an angle to the outer wall 152.

[0026] In the exemplary embodiments according to Fig. 1, Fig. 3 and Fig. 4. The first rosette part 130 is designed as a wall plate and the second rosette part 140 as a nut. The first rosette part 130 has a first contact area 132 and the second rosette part 140 a second contact area 142, as shown, for example, in the Fig. 5 to 7 are visible.

[0027] The two contact areas 132, 142 are each spherically shaped with a radius R2, R3, with the first contact area 132 being concave and the second contact area 142 being convex.

[0028] In the embodiment according to Fig. 4. The radii R2, R3 of the two contact areas 132, 142 are equal to a radius R1 of the common contact area 122. In this way, a reliable angular compensation between the two rosette parts 130, 140 and uniform friction during movement along the common contact area 122 can be achieved.

[0029] Furthermore, the first rosette part 130 has an inner diameter D2 and the second rosette part 140 has an inner diameter D1. The inner diameter D1 of the second rosette part 140 is smaller than the inner diameter D2 of the first rosette part. This allows for angular compensation between the two rosette parts 130 and 140, or between the intermediate tube 80 and the outer wall 152.

[0030] In the present embodiment, the intermediate tube 80 is aligned at an angle α deviating from 90° between the intermediate tube 80 and the outer wall 152. Due to the smaller diameter D2 of the second rosette part 140 compared to the diameter D1 of the first rosette part 130, the rosette parts 130 and 140 can move relative to each other in such a way that angular compensation is possible, allowing the first rosette part 130 to lie flush against the outer wall 152. The spherical contact areas 132 and 142 slide over one another. The angular compensation is limited, among other things, by the dimensions of the two rosette parts. The rosette parts 130 and 140 are dimensioned such that angular compensation of up to 6° is possible. The inner diameters of the contact areas 132 and 142 of the two rosette parts 130 and 140 in the embodiments according to the embodiments are also Fig. 1 and Fig. 3 are dimensioned in this way.

[0031] How Fig. As illustrated in Figure 8, the second rosette part 140 has identically curved contact areas 142 on opposite end faces, which are designed to abut the first contact area 132. The curvature in the exemplary embodiment is determined by the Fig. The radius R shown in section 8 specifies the second contact area 142 on one end face of the rosette part 140. The same applies to the opposite and Fig. 8 within the second contact area formed by the radius R 142.

[0032] This prevents the second rosette part 140, designed as a union nut, from being incorrectly aligned and connected to the intermediate pipe. The frost-proof outlet fitting according to the invention can therefore be assembled correctly with greater certainty.
