Definitions

  • the present invention relates to a sanitary fitting with a cold water connection, a hot water connection and at least one water outlet.
  • the cold water connection, the hot water connection and the at least one water outlet can be formed in a fitting body in which lines are also formed which connect the cold water connection and the hot water connection with the at least one water outlet.
  • At least one receptacle can be formed in the fitting body.
  • a mixing cartridge can be arranged in the receptacle to adjust the mixing ratio of hot and cold water and, if necessary, to adjust the flow.
  • Further receptacles can also be formed, in which, for example, a switching device from a first water outlet to a second water outlet is arranged.
  • Such a sanitary fitting can be connected to a building-side pipe using a connection device.
  • the cold water connection is connected to a building-side cold water pipe by means of a first connection device and the hot water connection is connected to a building-side hot water pipe by means of a second connection device.
  • connection device each has a so-called S-connection, the structural design of which can offer helpful compensation for dimensional deviations between the connections of the building's water pipes and the water connections of the fitting.
  • Such an S-connection has a first end with which the S-connection can be connected to the building-side water pipe.
  • the S connection has a second end to which the sanitary fitting is connected, if necessary using other components.
  • the S-port extends from the first end in an axial direction, with the second end offset transversely of the first end.
  • connection arrangement comprises a clamping element, which can be displaced against a connection element by means of an expansion element. In this way, a non-positive connection is provided between the sanitary fitting and the connection device.
  • the elements of the connection arrangement are provided as separate components, so that the connection arrangement must be handled manually and separately for each line.
  • the object of the present invention is therefore to eliminate the disadvantages described with reference to the prior art and in particular to propose a sanitary fitting that can be mounted easily and in particular at a predetermined distance from a wall.
  • a sanitary fitting with the features mentioned at the outset, wherein the cold water connection and the hot water connection can each be connected to a building-side line by means of a connection device and in which at least one locking element on the sanitary fitting is movable, for example linearly displaceable, between an unlocking position and a locking position , is rotatably or pivotally mounted, wherein the sanitary fitting can be placed on the connection devices in the unlocking position and is secured against removal from the connection devices in the locking position.
  • the basic idea of the invention is that a locking element is captively mounted on the sanitary fitting in such a way that it can be moved back and forth between two positions.
  • the sanitary fitting and in particular the locking element are set up in such a way that the sanitary fitting can be placed on the connection devices already installed on the building and in an attached state the locking element can be moved into the locking position.
  • the locking element is in particular designed so that it interacts with the connection devices in the locking position, so that the sanitary fitting is securely fastened to the connection devices and therefore cannot be easily removed from the connection devices. Since the at least one locking element is mounted on the sanitary fitting, it does not have to be handled separately during installation. This simplifies the assembly process.
  • exactly one locking element is designed with which the sanitary fitting can be secured to the two connection devices at the same time.
  • the locking element is spring-biased into the locking position by means of a spring. Assembly is also simplified using such a spring preload.
  • the at least one locking element can be held in the unlocking position by means of at least one securing element, in which the sanitary fitting can be placed on the connection devices. After the fitting is placed on the connection devices, the securing element can be removed so that at least one Locking element can reach its locking position due to the spring preload.
  • the sanitary fitting can be designed such that the locking element non-positively fixes the sanitary fitting in the locking position on the connection devices.
  • the sanitary fitting and, if applicable, the connection devices are designed in such a way that the sanitary fitting is secured in the locking position in a form-fitting manner on the connection devices against removal by means of the at least one locking element.
  • This can be achieved in particular by forming a type of undercut on the connection device, which is engaged behind by the at least one locking element in the locking position. In the locking position, the locking element is arranged relative to the undercut so that the sanitary fitting cannot be removed from the connection devices.
  • Such an undercut design which is also referred to as a form-fitting design, can be formed, for example, by a circumferential groove on the connection device. In the locking position, the at least one locking element then engages in sections with an edge in the circumferential groove.
  • the locking element has a recess for each connection device, which is shaped such that the connection device can reach through the recess in the unlocking position and a Edge of the recess comes into engagement with a positive locking design on the connection device when transferred into the locking position.
  • the recess can have a first portion that is defined by a first diameter, the first diameter being so large that the locking element can be placed on the connection device.
  • the recess has a second area which is characterized by a second diameter which is smaller than the first diameter, with an edge of this second area in the locking position interacting with the positive locking design preventing the sanitary fitting from being removed from the connection devices.
  • the locking element is slidably mounted on the sanitary fitting.
  • the locking element is mounted displaceably directly on the fitting body, so that forces from the locking element can be transferred directly to the fitting body.
  • the locking element is displaceable in a direction that is predetermined by a direction from the hot water connection to the cold water connection.
  • a particularly simple actuation of the locking element is possible thanks to a linearly displaceable bearing.
  • spring preload can easily be implemented with a linearly displaceable bearing.
  • the locking element is at least partially C-shaped in cross section, with the locking element preferably having recesses in a flat main section for receiving the connection devices and being displaceably mounted on the fitting body with free end sections.
  • the locking element is both in the area of Cold water connection as well as in the area of the hot water connection on the fitting body is slidably mounted, the locking element being C-shaped in cross section precisely in these areas.
  • the free ends of the locking element engage in linear grooves formed on the fitting body, so that the direction of displacement of the locking element is predetermined by the grooves on the fitting body.
  • the recesses already described above, which accommodate the connection devices are formed in the flat and flat main section connecting the free ends.
  • the sanitary fitting comprises a housing.
  • the housing is in particular designed so that it largely covers the fitting body, with the housing coming into contact with an edge against a wall in the assembled position.
  • Control elements for operating the sanitary fitting can be passed through the housing or arranged in the housing.
  • the housing can in particular also have an opening through which the at least one water outlet of the fitting body is accessible.
  • the locking element has an actuation projection, by means of which the locking element can be actuated from outside the housing.
  • the actuating approach which is in particular formed in one piece with the locking element, extends in particular through an opening in the housing, whereby the opening can also be provided for other connecting parts or other functions. With the actuation approach, the locking element can be transferred from the locking position into the unlocking position, in particular against the spring force.
  • the locking element in the locking position covers the water outlet formed on the fitting body. This ensures that, for example, a hose of a hand shower cannot be connected to the water outlet until the locking element has been moved into the locking position.
  • a hose screwed into the water outlet secures the locking element against being transferred from the locking position to the unlocking position.
  • the invention also relates to a sanitary fitting assembly kit which, in addition to a sanitary fitting according to the invention, comprises two connection devices, the connection devices each having a positive locking design which engages behind the locking element in the locking position in order to prevent the sanitary fitting from being removed from the connection devices.
  • a form-fitting design (for example in the form of an undercut or in particular as a circumferential groove) is formed on the connection device, with which the locking element interacts in its locking position when attempting to remove the sanitary fitting from the connection devices in such a way that removal is prevented.
  • the connection device includes in particular a conventional, water-conducting S-connection or an alternative water-conducting connection element.
  • the S-connection and the water-carrying connection element have a first end with which the S-connection or the water-carrying connection element can be connected to a building-side pipe, with the S-connection or the water-carrying element extending away from the first end in an axial direction extends, wherein a second end of the S-connection or of the water-conducting connection element, onto which the sanitary fitting can be attached (if necessary using further components), is arranged offset transversely to the axial direction.
  • the form-fitting design is formed in particular on an element of the connection device, which can be brought into different positions along an axial direction of the connection device.
  • the form-fitting design is formed on a screw ring that is screwed onto the S-connection or the water-conducting connection element.
  • the screw ring is screwed from the second end onto the S connection or the water-conducting connection element.
  • a position of the form-fitting design can thus be adapted to the respective installation situation, so that the sanitary fitting and in particular a housing of the sanitary fitting rests flush against the wall after being put on, so that through the Screwed on screw ring specifies a distance between the sanitary fitting and the wall.
  • the form-fitting design is formed in one piece on the water-conducting connection element.
  • connection device can comprise a radially acting seal and an axially acting seal.
  • the radially acting seal is in particular arranged so that it is arranged directly between the connection device and the corresponding connection of the sanitary fitting when the sanitary fitting is applied to the connection devices.
  • the radially acting seal is arranged in particular in a radially circumferential groove on the connection device.
  • connection device comprises an end cap that can be screwed onto a conventional S-connection.
  • a circumferential groove is formed in a lateral surface of the end cap, in which the radially acting seal is arranged.
  • an axially acting seal is arranged between the end cap and an axial end face of the S-connection at its second end.
  • the water-conducting connection element has at its second end a groove running around its lateral surface, in which the radially acting seal is arranged.
  • the installation of an end cap can therefore be dispensed with, and consequently the axial seal can also be dispensed with in this alternative embodiment.
  • the sanitary fitting assembly kit comprises a securing element by means of which the locking element is held in the unlocking position before the sanitary fitting is placed on the connection devices.
  • the securing element is preferably arranged in an opening in the housing of the sanitary fitting, which is assigned to the water outlet of the fitting body.
  • the securing element cooperates in particular with an actuation approach formed on the locking element.
  • Sanitary fitting 1 shown comprises a fitting body 7, a housing 8 and a locking element 6.
  • the fitting body 7 forms a cold water connection 3, a hot water connection 4 and a water outlet 5.
  • the fitting body 7 forms lines which lead from the cold water connection 3 or from the hot water connection 4 to a receptacle for a single-lever mixing cartridge and from there to the water outlet 5.
  • the single-lever mixing cartridge protrudes beyond the housing 8 so that an actuating element can be operated by a user, with which both the mixed water temperature and the flow can be adjusted.
  • the locking element 6 is slidably mounted on the fitting body 7. Like in particular from the Figure 3 As can be seen, the locking element 6 is C-shaped in the area of the hot water connection 4 and the cold water connection 3, with the free end sections 6.4 of the locking element 6 engaging in corresponding recesses on the fitting body 7. In the flat and flat main section 6.3 of the locking element 6, which is formed between the end sections 6.4, there are a first recess 6.1 and a second recess 6.2. In addition, the locking element 6 has an actuation approach 6.5 (see in particular Figures 4 and 5 ), which protrudes through an opening in the housing 8.
  • connection devices 2 In the in Figures 1 to 5 In the configurations shown, the sanitary fitting 1 with its cold water connection 3 and its hot water connection 4 is each placed on a connection device 2.
  • connection devices 2 In Figure 6 are also the ones in the Figures 1 to 5 connection devices 2 shown.
  • Figure 7 shows an alternative embodiment of two connection devices 2.
  • connection device 2 shown comprises a conventional S-connection 12, which extends from a first end, with which the S-connection 12 can be attached to a building-side line, to a second end, the first end and the second end being arranged offset from one another .
  • a screw ring 13 is screwed onto the second end, which has a positive locking design 11 in the form of a circumferential groove.
  • the screw ring 13 also has a section which, when assembled, comes into contact with a wall (not shown).
  • An end cap 18 is also screwed onto the second end of the S-connection 12, which carries a radial seal 16 on its lateral surface, for which purpose the lateral surface has a circumferential groove.
  • the connection device 2 also includes an axial seal 17, which is arranged between the end cap 18 and an axial end face of the S-connection 12.
  • connection devices 2 shown differ from the connection devices 2 of the Figure 6 in that instead of a conventional S-connection, a connection element 14 is used, at the second end of which a radial seal 16 is arranged.
  • a connection element 14 is used, at the second end of which a radial seal 16 is arranged.
  • the second end of the connecting element 14, which is offset from the first end has a circumferential groove on its lateral surface in which the radial seal 16 is arranged.
  • the recesses 6.1 and 6.2 formed in the main section 6.3 of the locking element 6 have a first section, the diameter of which is chosen to be so large that the sanitary fittings in the Figures 1 and 4 shown unlocking position can be placed on the connection devices 2.
  • the screw ring 13 with the form-fitting design 11 passes through the recess assigned to it. Due to the preload provided by a spring 15, the locking element can be in the Figures 2 and 5 reach the locking position shown, in which the edge of the respective recess 6.1 and 6.2 reaches the positive locking design 11. A positive connection is thus established between the locking element 6 and the screw ring 13, so that the sanitary fitting 1 cannot be removed from the connection devices 2.
  • the locking element 6 is held in the unlocking position by a securing element 10.
  • the securing element 10 is inserted into an opening in the housing 8, the securing element 10 fixing the actuating projection 6.5 of the locking element 6 so that the locking element 6 is held in the unlocking position against the spring preload.
  • the sanitary fitting 1 can be placed on the connection devices 2 that are already connected to the building-side pipes.
  • the securing element 10 can be removed so that the locking element 6 moves in the direction of the locking position. If the sanitary fitting 1 is aligned with the connection devices 2 so that the locking element 6 can engage with the edges of the recesses 6.1 and 6.2 in the positive locking designs 11, the locking element is in the locking position.
  • the water outlet 5 on the fitting body 7 is only released when the locking element 6 is in the locking position. In this position, a hose 9 can be screwed into the water outlet 5.
