Description

The invention relates to a fastening arrangement for a fitting and a method for fastening a fitting with a fastening arrangement. The valve can on the mounting arrangement such. B. on a sanitary facility, for. B. a sink, a bathtub or the like. The fitting is in particular a mixer tap or a tap.

Faucets are usually screwed to a sink or sink. The screw connection is usually only accessible from the underside of the sink or washbasin.

The object of the present invention is to at least partially solve the problems mentioned with reference to the prior art. In particular, the attachment of a fitting should be simplified. Preferably, the attachment of the fitting to the sanitary system should be made possible from the side from which the fitting is supplied or on which it is arranged.

A fastening arrangement with the features according to patent claim 1 and a method according to patent claim 14 contribute to solving these tasks. Advantageous further developments are the subject of the dependent claims. The features listed individually in the patent claims can be combined with one another in a technologically sensible manner and can be supplemented by explanatory facts from the description and / or details from the figures, further embodiment variants of the invention being shown. A mounting arrangement for a fitting is proposed. The fastening arrangement comprises at least one housing and a first locking component and a second locking component. The locking components form a fixed connection with one another at least with respect to an axial direction. One of the locking components is arranged movably in the housing to produce the connection of the locking components with respect to the housing. At least one of the locking components has a first contact surface that is inclined with respect to a radial direction (runs perpendicular to the axial direction) for contacting a second contact surface of the other locking component, with the first contact surface (or the first locking component) being displaced relative to the second contact surface ( or the second locking component) along the radial direction, the locking components can be displaced relative to one another along the axial direction for generating or for releasing the connection.

In particular, the locking component movably arranged in the housing is arranged in a first position when the connection between the locking components is established, that is, when the fitting is connected to e.g. B. is attached to a sanitary facility. Correspondingly, the locking component movably arranged in the housing is arranged in a second position when the connection between the locking components is released, ie when the fitting can be released from the sanitary system.

In the first position, the fitting, in particular, can no longer be moved relative to the sanitary system (compared to when it is used as intended) occurring forces). This can be seen as a "locked" position.

The housing can be a housing part of the fitting or part of the sanitary system. The housing can be designed in the manner of an insert or adapter which can be used in a fitting housing.

The first contact surface extends (in the area of contacting the second contact surface) in particular at an angle of up to 20 degrees with respect to the radial direction, the angle being more than 0 degrees. As a result of the course at an angle, a wedge-shaped surface can be formed, so that when the first locking component moves along the radial direction, there is a relative movement of the two locking components along the axial direction.

The second contact surface can run parallel to the radial direction. Alternatively, it is possible that the second contact surface is also inclined with respect to the radial direction. The explanations for the first contact surface apply accordingly.

The inclination of the contact surface (s) leads, in particular, to a displacement of the contact surfaces relative to one another along the radial direction that the locking components are displaced along the axial direction. Is the first locking component z. B. fixed to the axial direction with the housing, the housing is moved together with the first locking component along the axial direction.

In particular, only the first locking component can be moved at least along the radial direction, the first locking component having the first contact surface.

In particular, the first locking component and the second locking component do not form a screw connection with one another, and are therefore not connected to one another via a thread. This includes a contact surface between the locking components, which extends at least 270 angular degrees around the axial direction, that is to say in a circumferential direction.

The second locking component is preferably a pin which extends along a first axial direction up to a first end and has a second contact surface at the first end which points in an opposite second axial direction.

In particular, the second locking component is connected to the sanitary system (but possibly to the fitting).

The second locking component is preferably connected to the sanitary installation, the first locking component being connected to the fitting. The fitting can be arranged on the sanitary system by connecting the first locking component to the second locking component.

According to a first embodiment, the fastening arrangement additionally comprises a one arranged in the housing and extending along the radial direction and rotatable relative to the housing about its own longitudinal axis Pen. The first locking component can be moved by the pin. The first locking component can be pivoted about the longitudinal axis or can only be displaced along the radial direction.

In particular, the first locking component is firmly connected to the pin, so that rotation of the pin causes the first locking component to pivot.

In particular, the pin can interact with the first locking component via a toothing, so that the first locking component can be displaced along the radial direction by rotating the pin in the housing.

According to another embodiment, the fastening arrangement additionally comprises a pin arranged in a rotationally fixed manner in the housing. The first locking component is pivotable about an axis of rotation extending along the radial direction, which is formed by the pin. The pin extends from a first pin end through a first opening of the first locking component to a second pin end.

In particular, the pin can interact with the housing via stop faces, so that rotation of the pin about the axis of rotation is prevented.

In particular, the first locking component is rotatably mounted on the pin, so that the first locking component can be pivoted relative to the pin.

The first locking component can in particular be moved between a first position and a second position, the connection being produced in the first position and the connection being released in the second position.

In particular, the fastening arrangement additionally comprises at least one spring element, the first locking component being able to be moved into the first position by a spring force of the at least one spring element.

In particular, the first locking component can thus only be pivoted against the spring force into the second position, in which the connection can be released.

The first locking component is preferably formed by two sub-components, each of which (ie each sub-component) can be moved between a first position and a second position. The at least one spring element is arranged between the sub-components, so that the spring force acts exclusively between the sub-components.

In particular, the partial components are thus pressed apart by the spring force on one side of the axis of rotation, so that the partial components are pressed together on the other side of the axis of rotation.

In particular, the first contact surfaces are formed on each sub-component, so that the connection can be established or released again by pivoting the two sub-components.

In particular, the pin extends with the second pin end into the housing and has a first thread on the second pin end. The pin can be displaced along the radial direction by screwing with a first counter thread arranged in the housing, so that the first locking component can be fixed in a first position that produces the connection.

In particular, the first locking component can therefore be arranged on the second locking component, the first locking component pivoted into the first position and fixed in this first position by screwing the pin, in particular being clamped between the pin and the housing.

In particular, the first locking component can be clamped or clamped due to the screwing between the first pin end and the housing.

In particular, the fastening arrangement additionally comprises at least one first friction plate, which is arranged in or on the housing (for example on a wall of the housing) between the housing (for example between a wall of the housing) and the first locking component. The force required to pivot the first locking component is increased by the first friction plate.

In particular, the fastening arrangement additionally comprises a second friction plate, which is arranged in the housing between the first pin end and the first locking component, one through the second friction plate force required for pivoting the first locking component is increased.

Each friction plate is particularly z. B. can be arranged or arranged via a clip element or a hook on the respective sub-component or the first locking component.

The friction plate has in particular a surface which increases the static friction between the contacting surfaces (friction plate and housing; friction plate and partial component or first locking component; friction plate and pin or first pin end).

In particular, the fastening arrangement additionally comprises a counter pin which is arranged in the housing and forms the first counter thread. The counter pin extends along the radial direction and starting from a first counter pin end into the housing and beyond the second pin end.

The execution of the first counter thread on a counter pin enables the pin in the housing to be secured against rotation, the counter pin being rotatable about the axis of rotation.

In particular, the fastening arrangement additionally comprises an outer housing, which encloses the housing in the radial direction on the outside, and a screw element (for example a screw). The counter pin has a second thread in the area of the first counter pin end. The screw element has one with the second thread cooperating second counter thread. The screw element extends through the outer housing, the screwing with the second counter thread of the counter pin and above the pin being displaceable along the radial direction, so that the first locking component can be fixed in a first position producing the connection.

The screw element is supported in relation to the radial direction, in particular on the outer housing. By screwing the screw element, the pin and, via the first pin end, the first locking component, or the partial components, or the friction plate, or the friction plates, or the locking components mentioned together, can be displaced against the housing and thereby pressed together. The first locking component can thus be fixed in a first position that creates the connection, so that the fitting is firmly connected to the sanitary installation.

In particular, when the screw element is released, the first locking component can be pivoted relative to the housing, in particular as a result of the spring force applied by the at least one spring element. In particular, the first locking component can then be shifted into a second position and back into the first position by the spring force.

A method for fastening a fitting to a wash basin is also proposed. The fastening arrangement comprises at least one housing and a first locking component and a second locking component. One of the locking components is in the housing for generation a connection of the locking components arranged movably with respect to the housing. At least one of the locking components has a first contact surface which is inclined with respect to a radial direction for contacting a second contact surface of the other locking component, the locking components being displaced relative to one another along the axial direction by moving the first contact surface relative to the second contact surface and so create the connection.

Correspondingly, a method for releasing an attachment of a fitting from a wash basin can be proposed, wherein the locking components relative to one another along the axial direction (reversed or opposite) by (reverse or opposite) displacement of the first contact surface relative to the second contact surface along the radial direction ) can be relocated and thus disconnect.

The statements relating to the fastening arrangement can in particular be transferred to the method and vice versa.

As a precaution, it should be noted that the numerals used here ("first", "second", ...) serve primarily (only) to differentiate between several similar objects, sizes or processes, in particular no dependency and / or sequence of these objects, sizes or dictate processes to each other. If a dependency and / or sequence is necessary, this is explicitly stated here or it obviously results for the person skilled in the art when studying the specifically described configuration. If a component can appear more than once ("at least one"), the description can be closed one of these components applies equally to all or part of the majority of these components, but this is not mandatory.

The Fig. 1 shows a fastening arrangement 1 for a valve 2. The fastening arrangement 1 comprises a housing 3 and a first locking component 4 and a second locking component 5. The locking components 4, 5 form a fixed connection 7 with respect to an axial direction 6. The first locking component 4 is movably arranged in the housing 3 to produce the connection 7 of the locking components 4, 5 relative to the housing 3. Both locking components 4, 5 have a first contact surface 9, which is inclined with respect to a radial direction 8 (runs perpendicular to the axial direction 6), for contacting a second contact surface 10 of the other locking components 5, 4, whereby by moving the first contact surface 9 (or the first locking component 4) relative to the second contact surface 10 (or the second locking component 5) along the radial direction 8, the locking components 4, 5 are displaceable relative to one another along the axial direction 6 for producing or for releasing the connection 7.

The second locking component 5 is a pin which extends along a first axial direction 11 to a first end 12 and on which first end 12 has a second contact surface 10 pointing in an opposite second axial direction 13. The pin, that is to say the second locking component 5, is connected to the sanitary system, that is to say the wash basin 39, the first locking component 4 being connected to the fitting 2 (for example a water tap). The fitting 2 can be arranged on the sanitary system 39 via the connection 7 of the first locking component 4 with the second locking component 5. For this purpose, the pin is screwed underneath the wash basin 39 and extends along the first axial direction 11 through a tensioning washer 38. The tensioning washer 38 arranged on the top of the wash basin 39 and the screw connection on the underside of the wash basin 39 make the pin, ie the second locking component 5, firmly connected to the sink 39.

The first locking component 5 is arranged in the housing 3 (the fitting 2), an outer housing 32 surrounding the housing 3 on an outer circumferential surface.

Fig. 2 shows part of the mounting arrangement 1 after Fig. 1 in a perspective view in an exploded view. Fig. 3 shows the part Fig. 2 in a first position 22 in a perspective view. Fig. 4 shows the part Fig. 3 in a second position 23 in a perspective view. Fig. 5 shows a detail of the part after Fig. 2 and 3rd in a perspective view. Fig. 6 shows the part Fig. 3 together with the second locking component 5 in a side view in a first position 22. Die 2 to 6 are described together below. To the explanations Fig. 1 is referred.

The fastening arrangement 1 additionally comprises a pin 16 arranged in a rotationally fixed manner in the housing 3. The first locking component 4 can be pivoted about an axis of rotation 17 which extends along the radial direction 8 and is formed by the pin 16. The pin 16 extends from a first pin end 18 through a first opening 19 of the first locking component 4 to a second pin end 20.

The pin 16 cooperates with the housing 3 via stop surfaces 40, so that rotation of the pin 16 about the axis of rotation 17 is prevented. The first locking component 4 is rotatably mounted on the pin 16, so that the first locking component 4 can be pivoted relative to the pin 16. The first locking component 4 is between a first position 22 ( Fig. 3 ) and a second position ( Fig. 4 ) movable, the connection 7 being generated in the first position 22 and the connection 7 being released in the second position 23. The fastening arrangement 1 additionally comprises a spring element 21, wherein the first locking component 4 can be moved into the first position 22 by a spring force 24 of the spring element 21. The first locking component 4 can thus only be pivoted against the spring force 24 into the second position 23, in which the connection 7 can be released.

The first locking component 4 is formed by two sub-components 25, each of which (ie each sub-component 25) can be moved between a first position 22 and a second position 23. The spring element 21 is arranged between the sub-components 25, so that the spring force 24 acts exclusively between the sub-components 25. The sub-components 25 are thus pressed apart by the spring force 24 on one side of the axis of rotation 17, so that the sub-components 25 on the other side of the Axis of rotation 17 (to create the connection 7 via the contact surfaces 9, 10; see Fig. 6 ) are squeezed together.

The pin 16 extends with the second pin end 20 along the radial direction 8 (further) into the housing 3 and has a first thread 26 on the second pin end 20. The pin 16 is screwed to a first counter thread 27 arranged in the housing 3 (see 7 to 12 ) can be displaced along the radial direction 8, so that the first locking component 4 can be fixed in a first position 22 producing the connection 7.

The first locking component 4 can be arranged on the second locking component 5, which is pivoted into the first position 22 and fixed in this first position 22 by screwing the pin 16, here by jamming between pin 16 and housing 3.

The fastening arrangement 1 additionally comprises a first friction plate 28 and a second friction plate 29, which in or on the housing 3 (here in each case on a wall of the housing 3) between the housing 3 (for example between a wall of the housing 3) and the first locking component 4 is arranged (see 7 to 12 ). The friction plates 28, 29 increase the force required to pivot the first locking component 4. Each friction plate 28, 29 is arranged on the respective sub-component 25 or the first locking component 4 via a clip element or via a hook.

The friction plates 28, 29 have a static friction between the contacting surfaces (friction plate 28, 29 and housing 3; friction plate 28, 29 and Subcomponent 25 or first locking component 4; Friction plate 28 and pin 16 or first pin end 18) increasing surface.

Fig. 7 shows part of the mounting arrangement 1 after Fig. 1 in a perspective view in section in an exploded view. Fig. 8 shows the part Fig. 7 in a perspective view in section. Fig. 9 shows the part Fig. 8 in a side view in section. Fig. 10 shows the part 8 and 9 with an outer housing 32 in a perspective view in section. Fig. 11 shows the part Fig. 10 in a side view in section. Fig. 12 shows the mounting arrangement 1 after Fig. 1 before connecting in a perspective view. The 7 to 12 are described together below. On the comments on the 2 to 6 is referred.

The fastening arrangement 1 additionally comprises a counter pin 30, which is arranged in the housing 3 and forms the first counter thread 27. The counter pin 30 extends along the radial direction 8 and starting from a first counter pin end 31 into the housing 3 as far as beyond the second pin end 20 of the pin 16. The execution of the first counter thread 27 on a counter pin 30 enables the pin 16 to be secured in or on the housing 3 against rotation, the counter pin 30 being rotatable about the axis of rotation 17.

The fastening arrangement 1 additionally comprises an outer housing 32, which includes the housing 3 in the radial direction 8 on the outside, and a screw element 33 (here a screw). The counter pin 30 has a second thread 34 in the area of the first counter pin end 31. The screw element 33 has a second counter thread 35 which interacts with the second thread 34 on. The screw element 33 extends through the outer housing 32, the screwing with the second counter thread 35 of the counter pin 30 and above the pin 16 being displaceable along the radial direction 8, so that the first locking component 4 in a first position producing the connection 7 22 can be fixed.

The screw element 33 is supported on the outer housing 32 with respect to the radial direction 8. By screwing the screw element 33, the pin 16 and, via the first pin end 18, the first locking component 4, or the subcomponents 25, or the friction plates 28, 29, or the locking components mentioned together, can be displaced against the housing 3 and thereby are pressed together. The first locking component 4 can thus be fixed in a first position 22 which produces the connection 7, so that the fitting 2 is firmly connected to the sanitary installation, here to the wash basin 39.

When the screw element 33 is loosened, the first locking component 4 can be pivoted relative to the housing 3, in particular against the spring force 24 applied by the one spring element 21. In particular, the first locking component 4 can then move into a second position 23 and back into the position by the spring force 24 first position 22 are shifted.

Fig. 13 shows a first embodiment of the fastening arrangement 1 in a perspective view in section. Fig. 14 shows the mounting arrangement 1 after Fig. 13 in a second position 23 in a side view. Fig. 15 shows the mounting arrangement 1 after Fig. 13 in a first position 22 in a side view. The 13 to 16 are described together below.

The fastening arrangement 1 comprises a housing 3 and a first locking component 4 and a second locking component 5. The locking components 4, 5 form a fixed connection 7 with respect to an axial direction 6. The first locking component 4 is movably arranged in the housing 3 to produce the connection 7 of the locking components 4, 5 relative to the housing 3. Both locking components 4, 5 have a first contact surface 9, which is inclined with respect to a radial direction 8 (runs perpendicular to the axial direction 6), for contacting a second contact surface 10 of the other locking components 5, 4, whereby by moving the first contact surface 9 (or the first locking component 4) relative to the second contact surface 10 (or the second locking component 5) along the radial direction 8, the locking components 4, 5 are displaceable relative to one another along the axial direction 6 for producing or for releasing the connection 7.

The second locking component 5 is a pin that extends along a first axial direction 11 up to a first end 12 and has a second contact surface 10 pointing in the opposite second axial direction 13 at the first end 12. The pin, that is to say the second locking component 5, is connected to the sanitary system, that is to say the wash basin 39 (not shown here), the first locking component 4 being connected to the fitting 2 (for example a water tap). The pin is e.g. B. screwed beneath the wash basin 39 and extends along the first axial direction 11 through a spring washer 38 (not shown here). Due to the clamping washer 38 arranged on the top of the wash basin 39 and the screw connection on the underside of the wash basin 39, the pin is thus the second locking component 5, firmly connected to the wash basin 39 (see, for example, Fig. 1 ). A guide element 37 arranged in the housing 3 is provided here, by means of which the armature 2 can be centered relative to the second locking component 5.

Here, the fastening arrangement 1 additionally comprises a pin 15 which is arranged in the housing 3 and extends along the radial direction 8 and can be rotated with respect to the housing 3 about its own longitudinal axis 14. The first locking component 4 can be moved by the pin 15. The first locking component 4 can be pivoted about the longitudinal axis 14. The first locking component 4 can be fixed in a second position 23 via a retaining spring 36. By rotating the pin 15, the first locking component 4 can be pivoted out of the second position 23 and into the first position 22, so that the connection 7 between the second locking component 5 (the pin) and the first locking component 4 is established.

Fig. 16 shows a second embodiment of the fastening arrangement 1 in a perspective view in section. Fig. 17 shows the mounting arrangement 1 after Fig. 16 in a second position 23 in a side view. Fig. 18 shows the mounting arrangement 1 after Fig. 16 in a first position 22 in a side view. The 16 to 18 are described together below. To the explanations 13 to 15 is referenced.

Here, the fastening arrangement 1 likewise comprises a pin 15 which is arranged in the housing 3 and extends along the radial direction 8 and can be rotated with respect to the housing 3 about its own longitudinal axis 14. The pin 15 interacts with the first locking component 4 via a toothing, so that the first locking component 4 can be displaced along the radial direction 8 by rotating the pin 15 in the housing 3. By rotating the pin 15, the first locking component 4 can be moved out of the second position 23 and into the first position 22 exclusively along the radial direction 8, so that the connection 7 between the second locking component 5 (the pin) and the first locking component 4 is made.
