Description

The invention relates to a tool for mounting and / or dismantling a sanitary insert part, in particular a sanitary outlet nozzle.From the prior art, tools for mounting and / or dismantling sanitary insert parts, such as sanitary outlet nozzles, also called jet regulators, are known. In the assembly / disassembly known from the prior art, the sanitary insert part, which is frequently fastened with a thread in a sanitary fitting, is screwed manually to the sanitary fitting with fingers. Subsequently, a tool can be used to tighten the sanitary insert. When screwing and handling with the aid of the fingers, the sanitary insert can easily fall out of the hand for the user. Also, the necessary torque for screwing the sanitary insert firmly cannot be applied well with the fingers.The object of the invention is to improve tools for mounting and dismounting sanitary inserts. It is also an object to improve the connection of the tool and the sanitary insert.To achieve the object mentioned, the features of claim 1 are provided according to the invention. In particular, it is thus proposed according to the invention for achieving the object mentioned that the tool has latching means designed for connection to the sanitary insert part. In this way, it can be achieved, for example, that the tool can be connected to the sanitary insert part. Due to the connection, a torque or another force, for example a compressive force or a tensile force, can be transmitted from the tool to the sanitary insert part. Alternatively or additionally, it can be provided that the tool has counter-latching means for connection to the sanitary insert part. In this way, it can be achieved, for example, that the tool can be connected to the sanitary insert part. Alternatively or additionally, it can be provided that the tool has latching means and / or counter latching means designed for a releasable connection to the sanitary insert part. In this way, it can be achieved, for example, that the latching means and / or counter-latching means of the tool can be released from the sanitary insert part, in particular that the latching means and / or counter-latching means can be released again after a connection.Alternatively or additionally, it is provided that the tool has latching means and / or counter latching means designed for a captive connection to the sanitary insert part. In this way, it can be achieved, for example, that the latching means and / or counter-latching means of the tool can be connected to the sanitary insert part in such a way that they are connected to one another in a captive manner, that is to say cannot be easily separated from one another while they are connected. An undesired loosening of the connection of tool and sanitary insert can thus be prevented. The tool can be connected to the sanitary insert part, wherein the latter can then be fastened to the tool in a sanitary fitting. This can be helpful in particular during mounting / dismounting work overhead or in an inclined position. With the aid of the tool, a captive connection can be produced between the tool and the sanitary insert, so that the sanitary insert does not have to be screwed with the hands and fingers into the sanitary outlet fitting during assembly / disassembly, but can be screwed in with the tool. Thus, the sanitary insert part can no longer fall out of the hand. The tool also offers the fingers an advantageous engagement surface compared to the sanitary insert part. The tool can thus be connected to the sanitary insert part, wherein the tool carries the sanitary insert part. The captive connection results in the sanitary insert part being easier to install. Faulty screwing-in of the sanitary insert part and resulting defects on the jet regulator or the fitting can thus be prevented. After the sanitary insert is screwed firmly with the tool, the tool can be detached from the sanitary insert. For dismantling the sanitary insert, the tool is connected to the sanitary insert, it then being possible for the latter to be released by a screwing movement.A captive connection can be characterized, for example, by the fact that a minimum pull-out force is required to release the connection. For example, the captive connection can have a release force which initially increases with increasing distance and falls, for example suddenly falls, starting from a certain distance and / or when the connection is released, which can be very small.In an advantageous embodiment, it can be provided that the tool has a drive section. In this way, it can be achieved, for example, that the drive section is configured for the transmission of force and can transmit a torque. In particular, the drive section can have a wall. In this way, it can be achieved, for example, that the drive section can be hollow and the force transmission takes place via the wall. In particular, the drive section can have a cross-sectional contour that remains the same along its course. In this way, different geometries of the drive section can be possible, which can have a positive effect on the stability of the tool. The drive section can in particular be cylindrically shaped. In this way, it can be achieved, for example, that the drive section of the tool can be attached to a cylindrically shaped sanitary insert part. Alternatively, the driving portion may be polygonally shaped. In this way, it can be achieved, for example, that the drive section can be attached to a correspondingly polygonally shaped sanitary insert part. This can lead to the torque from the drive section being able to be transmitted advantageously effectively and efficiently to the sanitary insert part. Alternatively or additionally, it can be provided that the latching means is arranged on one side of the drive section. In this way, it can be achieved, for example, that the latching means of the tool can cooperate with a counter latching means of the sanitary insert part in order to produce a connection. Alternatively or additionally, it can be provided that the counter-latching means is arranged on one side of the drive section. In this way, it can be achieved, for example, that the counter-latching means of the tool can cooperate with a latching means of the sanitary insert part in order to produce a connection on the side of the drive section. In particular, it can be provided that the latching means and / or counter-latching means is arranged on a circulation of the drive section. In this way, it can be achieved, for example, that the latching means and / or counter-latching means can be connected particularly easily to the sanitary insert part.Alternatively or additionally, to achieve the object mentioned, the features of the subordinate claim 3 directed to a sanitary insert part are provided according to the invention. To achieve the object, a sanitary insert part is thus proposed, characterized in that the sanitary insert part has latching means designed to be connected to a mating latching means of a tool. In this way, it can be achieved, for example, that the sanitary insert part and the tool can be connected to one another. Due to the connection, a torque or another force, for example a pressure or a tension, can be transmitted from the tool to the sanitary insert part. In particular, it is provided that the sanitary insert part is a sanitary outlet mouthpiece. Alternatively or additionally, it is provided that the sanitary insert part has counter-latching means designed to be connected to a latching means of a tool. In this way, it can be achieved, for example, that the sanitary insert part and the tool can be connected to one another. Alternatively or additionally, it can be provided that the sanitary insert part has latching means and / or counter-latching means designed to be releasably connected to a latching means and / or counter-latching means of the tool. In this way, it can be achieved, for example, that the connection of sanitary insert part and tool can be released. This is necessary, for example, after the mounting of the sanitary insert part in a sanitary fitting. Alternatively or additionally, it can be provided that the sanitary insert part has latching means and / or counter-latching means designed to be connected to a latching means and / or counter-latching means of the tool in a captive manner. In this way, it can be achieved, for example, that sanitary insert part and the tool can be connected in a captive manner. This is advantageous for assembly because the sanitary insert part can be more easily connected to a sanitary fitting when it is previously fastened to the tool. In particular, it is provided that the sanitary insert part has latching means and / or counter-latching means designed to be connected to a latching means or counter-latching means of a tool according to claim 1, preferably in a releasable and / or captive manner. In this way, it can be achieved, for example, that latching means and counter-latching means are configured to correspond to one another, i.e. interact in a fitting manner.Alternatively or additionally, to achieve the object mentioned, the features of the subordinate claim 4 directed to a set of a tool and a sanitary insert part are provided according to the invention. To achieve the object, a set of a tool and a sanitary insert is thus proposed, wherein the tool is configured for mounting the sanitary insert, characterized in that the tool for mounting can be connected to the sanitary insert in a captive manner. In this way, it can be achieved, for example, that a sanitary insert can be connected to the tool in a captive manner. This is helpful during assembly, in particular during assembly in an inclined position or overhead, since the sanitary insert part can thus not be unintentionally separated from the tool. In particular, it can be provided that the sanitary insert part is a sanitary outlet mouthpiece. Alternatively or additionally, it can be provided that the tool is configured for dismantling the sanitary insert part and is characterized in that it can be connected to the sanitary insert part in a captive manner for dismantling. In this way, it can be achieved, for example, that a sanitary insert can be connected to the tool in a captive manner. This is helpful during disassembly, in particular during disassembly in an inclined position or overhead, since the sanitary insert part can thus not be unintentionally separated from the tool.In a preferred embodiment, it can be provided that the captive connection of tool and sanitary insert is effected by means of a positive fit. As a result, it can be achieved, for example, that the form-fitting connection blocks a relative movement of latching means and counter-latching means (and vice versa). In particular, the form-fitting connection can be a snap-fit connection. The latching element / counter-latching element deforms and enters into a releasable and / or captive connection with a corresponding counter-latching element / latching element. Alternatively or additionally, it can be provided that the captive connection of tool and sanitary insert is effected by means of a force fit. In this way, it can be achieved, for example, that the captive connection is achieved by high frictional forces between the latching element and the counter-latching element. In particular, the force-fit connection can be an interference fit. By means of a pressure force, the latching element / counter-latching element is pressed into a corresponding receptacle, wherein the receptacle is somewhat too small, or the latching element / counter-latching element is somewhat too large. The latching element / counter-latching element is thereby elastically deformed and high frictional forces between the latching element / counter-latching element and the receptacle lead to a connection that is secure against loss. By means of a tensile force, i.e. a pulling of the tool on the sanitary insert part, the positive fit and / or the frictional fit can be canceled.For mounting and / or dismantling a sanitary insert with the tool, it is proposed that the tool is connected to the sanitary insert in such a way that it cannot be lost for mounting. As a result, for example, a method for mounting a sanitary insert part with a tool can be achieved, characterized in that the tool is connected to the sanitary insert part in such a way that it cannot be lost for mounting purposes. It is advantageous here that the sanitary insert part, when connected to the tool, cannot be lost. However, it is connected to the tool in a captive manner. For mounting, the tool can be connected to the sanitary insert in a captive manner, wherein the sanitary insert is then arranged on the tool and can be fastened by means of the latter to a sanitary fitting. Alternatively or additionally, it can be provided that the tool is connected to the sanitary insert part in such a way that it cannot be lost for disassembly. In this way, it can be achieved, for example, that the sanitary insert part is secured to the tool in a captive manner during disassembly. During disassembly, for example unscrewing of the sanitary insert from a sanitary fitting, the sanitary insert is always securely connected to the tool and cannot be lost if the connection of the sanitary insert and the sanitary fitting is released.A preferred application of the invention provides that a connection of tool and sanitary insert is effected by means of positive locking. As a result, for example, a particularly stable and captive connection can be created, in which an undesired release of the connection is prevented. In particular, it is provided that the form fit is a snap fit. Snap connections represent a structurally simple type of a form-fit connection. Alternatively or additionally, it can be provided that the connection of tool and sanitary insert part is effected by means of frictional connection. A frictional connection due to friction between the latching element and the counter-latching element represents a structurally simple and captive fastening which is nevertheless releasable. In particular, the force-fit connection can be an interference fit. This can allow, for example, a simple and captive connection of the latching element and the counter-latching element. The connection can be released by a tensile force on the tool.A preferred application of the invention provides that a force is applied for releasing the tool from the sanitary insert part which is greater than the weight force of the tool. It can be achieved hereby, for example, that the tool can be released from the sanitary insert part when the force is greater than the weight force of the tool. In particular, it is provided that, for releasing the tool from the sanitary insert part, a tensile force is applied which is greater than the weight force of the tool. In this way, it can be achieved, for example, that the tool can be released from the sanitary insert part by a drawing. However, the connection of the sanitary insert part and the tool is not disconnected until the tensile force is higher than the weight force of the tool. Thus, unintentional detachment is prevented.The tool is made of plastic, which has the advantage that it is less hard than (stainless) steel or chrome plated applications of sanitary fittings and therefore cannot scratch them.In the case of aerated sanitary inserts, dirt and lime deposits can occur in the air intake region. These can be removed with the tool when the air intake openings are engaged with the latching means / counter latching means of the tool. Thus, an advantageous and uncomplicated removal of dirt can be carried out with the tool, which improves the function of the sanitary insert and extends its service life. In one embodiment of the invention, it can therefore be provided that the tool can be used to engage in the suction openings. Thus, the individual key webs can free the air intake region from dirt and lime deposits.The invention will now be described in more detail with reference to exemplary embodiments, but is not limited to the exemplary embodiments.

The tool 1 has a driving portion 7 which is cylindrically shaped. The latching means 4 is arranged on a circumferential path 8 of a side 9 of the drive section 7. On a side 10 of the tool 1 opposite the drive section 7, the tool 1 has a handle 11. the handle 11 serves for manual gripping and for transmitting a torque to the sanitary insert part 2. In the side view (FIG. 2 ), a thread 12 of the sanitary insert part 2 is shown. The sanitary insert part 2 can be screwed with the tool 1 into a sanitary fitting (not shown).In the exemplary embodiments shown, the drive section 7 has a wall. The drive section has a constant cross-sectional contour along its course. In the exemplary embodiments shown, the drive section is cylindrically shaped. In an embodiment not shown, the driving portion is polygonally shaped.FIG. 3 shows the latching means 4 of the tool 1, which interacts with the counter latching means 5 of the sanitary insert part 2 and enters into a releasable and captive, positive snap-fit connection 13. FIG. 4 shows the tool 1 without a sanitary insert part 2, In order to enable the positive snap connection 13 to take place, the latching means 4 are pressed into receptacles of the sanitary insert part 2. Conversely, the counter-latching means 5 of the sanitary insert part 2 are pressed into receptacles 17 of the tool 1. The latching noses 14 of the latching means 4 of the tool 1 are pressed against the counter latching noses 15 of the counter latching means 5 of the sanitary insert part 2. Latching means 4 and counter latching means 5 are elastically deformed by being compressed and thus latching into one another. The connection 6 can be released again by a tensile force 16.The sanitary insert part 2 has counter-latching means 5 in order to be connected to the latching means 4 of the tool 1 in a releasable and captive manner. In the sense of the patent specification, it is obvious that, depending on the way in which the locking means 4 and the counter-locking means 5 are viewed, the locking means 4 and the counter-locking means 5 are also arranged in the opposite direction on the tool 1 and the sanitary insert part 2. The figures show a set of tool 1 and sanitary insert part 2, wherein the sanitary insert part 2 is a sanitary outlet mouthpiece 3. The tool 1 is configured to mount and disassemble the sanitary insert 2. For this purpose, it can be connected to the sanitary insert part 2 in a captive manner. The captive connection 6 is effected by means of a positive fit and / or a non-positive fit. A positive connection 19 is shown in FIGS. 1 to 4 and 13 to 22. Here, the captive connection 6 is effected by a snap connection 13, i.e. a snap connection, wherein the latching nose 14 of the tool 1 is elastically deformed. The latching nose 14 then latches with the sanitary insert part 2 and creates a captive connection 6, which can be released, however, by a tensile force. This tensile force will initially increase with increasing distance during the elastic deformation of the latching nose 14 and then when the tensile force is removed.The resulting compound 6 is released and suddenly dropped off.The captive connection 6 of tool 1 and sanitary insert 2 is additionally or alternatively effected by frictional connection. A force-fit connection 20 is shown in FIGS. 5 to 12. Here, the frictional connection is realized by an interference fit 21. In the case of a frictional connection, a minimum force is required to overcome static friction, which drops abruptly when changing over to a sliding friction.Receptacles 17 on the drive section 7 of the tool 1 for the counter-locking means 5 of the sanitary insert part are designed to be somewhat smaller than the counter-locking means 5 of the sanitary insert part 2. the counter-locking means 5 can be pressed into the receptacles 17 by a pressure force 18, whereby the force-locking connection 20 is effected by an interference fit 21.A method for mounting the sanitary insert part 2 with the tool 1, wherein the tool 1 is connected to the sanitary insert part 2 for mounting in a captive manner, comprises the following steps. The tool 1 is connected to the sanitary insert part 2 by a compressive force 18. For this purpose, both parts are preferably held in the hands of a user. The latching means 4 / counter latching means 5 are inserted into corresponding receptacles 17. After the connection, the sanitary insert part 2 is connected to the tool 1 in a captive manner and can be moved therewith. The tool 1 and the sanitary insert 2 are then attached to an outlet of a sanitary fitting and screwed firmly. The latching means 4 and counter latching means 5 allow a force transmission from tool 1 to sanitary insert part 2.A method for disassembling the sanitary insert 2 with the tool 1, wherein the tool 1 is undetachably connected to the sanitary insert 2 for mounting, comprises the following steps. The tool 1 is connected by a compressive force 18 to the sanitary insert part 2, which is located in the outlet of a sanitary fitting. After the connection, the sanitary insert part 2 is connected to the tool 1 in a captive manner and can be moved therewith. By means of a rotational movement, the sanitary insert part 2 can be unscrewed from the sanitary fitting.During assembly and disassembly, the connection of tool 1 and sanitary insert part 2 takes place by positive locking and / or frictional locking. In order to release the tool 1 from the sanitary insert part 2, a tensile force 16 must be applied which is greater than the weight force of the tool 1.The tool 1 has a crown structure 22, which serves to transmit the torque from the tool 1 to the sanitary insert part 2. Where the latching means 4 and the counter latching means 5 are in contact on the crown structure 22, the torque can be transmitted. The latching means 4 and the receptacles 17 of the tool 1 are part of the crown structure 22, and the drive section 7 of the tool 1 is of hollow design. In an embodiment which is not shown, the drive section 7 is solid.A tool 1 and a method for mounting and / or dismantling a sanitary insert part 2, in particular a sanitary outlet nozzle 3, are proposed, characterized in that the tool 1 has latching means 4 and / or counter latching means 5 for a preferably releasable and / or captive connection 6 to the sanitary insert part 2.List of reference characters1 Tool 2 Sanitary insert part 3 Sanitary outlet mouthpiece 4 Latching means 5 Counter-latching means 6 Connection 7 Drive section 8 Circulation 9 Side 10 Opposite side 11 Handle 12 Thread 13 Snap connection 14 Latching lugs 15 Counter-latching lugs 16 Tensile force 17 Receptacles 18 Compressive force 19 Positive connection 20 Force-locking connection 21 Interference fit 22 Crown structure
