Definitions
- the present invention relates to a self-closing rotary control element and a water valve with a corresponding self-closing rotary control element.
- water fittings that have a base, an outlet and at least one rotating Bares actuator for opening and closing a water path in the water fitting.
- hot water fittings are known, via which water can be dispensed at a temperature above 80°C, in particular even about 100°C.
- Such hot water fittings are used in particular for hotplates, so that the cooking and cooking of food can be carried out particularly quickly and hygienically.
- the focus is on protection against scalding.
- the hot water fitting is unintentionally operated or that the supply of hot water is not interrupted in good time.
- the object of the present invention is to at least partially alleviate the problems described with reference to the prior art.
- a self-closing rotary actuator should be specified for a water fitting, which should only allow a waterway to be released with the help of complex movement and/or handling sequences.
- the focus here is on a type of child safety device that is intended to make the actuation of the water fitting more difficult.
- a self-closing rotary control element for a water fitting which has at least one gripping sleeve, which includes an outer part and a base part.
- the base part can be connected to a rotatable actuator of the water fitting.
- the outer part has at least one opening in which a spring-loaded push button can be positioned in a closed position.
- This spring-loaded push button can be connected to a rotary locking mechanism.
- a torsion spring is also provided, which causes an actuating force towards the closed position when the grip is adjusted.
- the rotary control element specified here can be designed in particular in the manner of a (water) faucet handle.
- the rotary control element comprises a plurality of parts which are optionally arranged essentially or at least in sections concentrically with one another and which can be adjusted in rotation together and/or in relation to one another.
- Self-closing means that these parts, in particular, rotate back to a so-called closed position (stable end position) after one rotation due to an actuating force generated by a torsion spring (internal) in relation to one another or in cooperation with a part that is firmly attached to a water fitting (stationary). .
- the gripping sleeve can in particular be a substantially cylindrical component which is provided with a cap on the end where appropriate.
- the outer surface which can optionally also have a surface structure for better handling, can be formed with a single outer part.
- the outer part preferably represents the outer peripheral surface of the gripping sleeve.
- the outer part has in particular a (radial) opening which is preferably designed to be round. It is possible for the outer part to have a plurality of openings, but the configuration in which the outer part has exactly one single opening in which the push button is positioned is preferred.
- the outer part can be made of metal and/or plastic.
- a base part is provided on the inside in the outer part or at least partially covered by it.
- the base part can be made of plastic and/or metal.
- the base part can be connected to a rotatable actuator of the water fitting, for example by means of a screw connection.
- the base part can, for example, have a recess on the face side, through which a screw can be fastened to the head of a rotatable actuator of the water fitting.
- the inner contour of the base part can essentially correspond to the outer contour of the actuator.
- the inside of the base forms a non-positive and/or positive connection with the actuator of the water fitting. In this way it can be achieved that when the base part is adjusted via the gripping sleeve, the actuator is rotated at the same time.
- the base part can also have a shape that implements a bearing for the spring-loaded push button. It is possible, with a spring supported on the base part, to press the pressure button against the outer part or into the opening of the outer part.
- the push button can interact with a rotary locking mechanism, so that in particular the rotary locking mechanism can be activated in a closed position of the rotary control element or of the actuator fixed thereto.
- the rotary locking mechanism is preferably without an external influence, such as. B. by pressing the push button in a (stable) locking position, so that rotation of the outer part relative to the base part is blocked without further ado. If this rotary locking mechanism is deactivated and there is a relative movement between the outer part and the base part, a rotary control element takes care of this integrated torsion spring to ensure that an actuating force is built up, which counteracts this adjustment movement, i.e.
- the outer part and base part are moved again (relative to one another) so that the rotary locking mechanism is activated again.
- the self-closing rotary element therefore requires two movement sequences, namely pressing the push button against the spring force and twisting the outer part also against a spring force, so that it is difficult for children to operate the fitting.
- these spring preloads ensure that if the rotary control element is released, it automatically moves back into its (safe and stable) closed position.
- the rotary actuator may have a first rotary limiter at the closed position and a second rotary limiter at an open position, the rotary locking mechanism being engageable at the first rotary limiter in the closed position.
- the rotation limiter extends into the angular range from the first rotation limiter in the closed position to the second rotation limiter in the open position. It is preferred here for the second rotation limiter to be designed as a non-stationary limiter, for example a stop is, so here the rotary control element does not remain independently, in particular without the intervention of a user.
- the rotary locking mechanism on the first rotary limiter assumes a stable position in the closed position, by engaging the twist-lock mechanism.
- a locked state is present in particular when components of the rotary control element are in positive engagement with one another, ie a mere displacement or rotation of the components relative to one another is prevented.
- first rotation limiter and the second rotation limiter be provided on an inner part that can rest on the inside of the base part and set a relative rotation of the base part and inner part of at least 40 angular degrees and a maximum of 180 angular degrees.
- the inner part can also be provided, at least in sections, in the manner of a sleeve. It is possible for the inner part to abut immediately internally against a portion of the base part where the base part may define a gap or slot through which a part of the rotary locking mechanism positioned on or outside of the base part can pass through and with can interact with the inner part underneath.
- the inner part can form the first rotation limiter (e.g. in the form of a recess) and the second rotation limiter (e.g. in the form of a protruding stop surface). It is possible that the first rotation limiter and the second rotation limiter are formed integrally with the inner part. In particular, it is possible to provide the inner part in a stationary manner on a housing part of the actuator or water fitting that cannot be rotated, so that the inner part is held stationary in the water fitting and the outer part and/or base part can rotate around it.
- the rotation of the base part relative to the inner part is preferably limited, specifically here in the range from 40 angular degrees to 180 angular degrees. The limitation of the relative rotation can be adjusted by the spatial position of the rotation limiters in relation to one another.
- a guide surface is provided between the first rotation limiter and the second rotation limiter, which are preferably arranged on a common circumferential line around the inner part, on which a part of the rotary locking mechanism is guided during relative rotation.
- the set relative rotation range is very particularly preferably in the range from 60 to 110 angular degrees, in particular approximately 90 angular degrees.
- the rotary locking mechanism comprises a displaceable and/or pivotable latch which can be actuated by moving the push button and which can be releasably locked in a latch recess.
- the bolt can be pivoted about an axis that is defined by bearing points in the base part. It is thus possible for the bolt to be spring-loaded on one side of the axis from the inside to the outside and thus stand or be locked on the opposite side of the axis with a bolt recess in the form of a grip.
- the push button can be provided above the spring-loaded section of the bolt, so that when it is pressed or pressed against the spring-loaded section of the bolt, the section of the bolt opposite the axis is removed from the bolt recess and is thus released. It is preferred that the latch recess is formed in the inner part.
- the push button and the bolt of the rotary locking mechanism can be actuated by a single compression spring.
- the compression spring ensures that the bolt is pressed with a spaced section in a latching position or a bolt recess and at the same time the push button is pressed into the opening of the outer part of the gripping sleeve.
- a water fitting which comprises a water pipe which is provided with a rotatable actuator for opening and closing the water pipe as required.
- the actuator is designed with a self-closing rotary actuator disclosed herein.
- the torsion spring is connected on the one hand to the base part and on the other hand to an abutment on the water fitting.
- the water fitting described here is in particular a so-called hot water fitting, ie the water line is connected to a heat source which can provide water at a temperature of more than 80°C, in particular approx. 100°C.
- the actuator in particular a mechanical rotary valve, can open and/or close the cross-section of the water line in the area of the water fitting, depending on the position of the actuator.
- the closed position of the self-closing rotary element corresponds to the closed position of the water pipe. It is also preferred that the open position of the self-closing rotary control element corresponds to the flow position of the water line. Consequently, the travel of the rotatable actuator can substantially match the maximum predetermined relative rotation of the base portion and the inner portion of the self-closing rotary member.
- the self-closing rotary control element is connected directly or indirectly to a rotatable element of the actuator, for example via a screw connection on the face side.
- the torsion spring is arranged on the one hand on the base part and is supported in a stationary manner on an abutment on the water fitting.
- the abutment can be formed immedi applicable to the water fitting, but it is also possible that the abutment is provided on a component that is stationary, d. H. in particular is not positioned in a rotational and adjustable manner in relation to the water fitting in the water fitting.
- the abutment it is possible for the abutment to be designed with an inner part of the self-closing rotary control element, with the inner part being fixed in place on the water fitting.
- an inner part can be provided which is connected to a fixed section of the actuator GeHouseab, wherein the torsion spring between the inner part and the base part is ver clamped.
- the voltage preferably has a minimum value when the relative rotation of the base part and the inner part is in the closed position. It is also preferred that in any other position of the inner part and the base part relative to one another, the torsion spring exerts a greater actuating force, which again acts towards the closed position.
- the actuator has a blind pivoting range of at least 20 angular degrees.
- the self-closing rotary control element does not yet release an opening in the water pipe of the water fitting over an angular pivoting range of at least 20 angular degrees.
- a pivoting range or a rotation must first be carried out without water flowing. It can thus be ensured that hot water is not already dispensed as a result of accidental, short or minor adjustment paths of the rotary control element.
- the blind pivoting range thus covers the first pivoting range after leaving the closed position. If the blind pivoting range is reached or exceeded, a pub is actually released in the water pipe, with this opening being able to grow closed until the maximum pivoting range of the rotary control element is reached.
- a self-closing rotary actuator of the type disclosed here is proposed for an actuating element of a hot water pipe of a water fitting and to make it difficult for children to operate it.
- the explanations for the self-closing rotary control element can also be used to characterize the water fitting and/or the use of the rotary control element, and vice versa.

- Fig. 5 a water fitting with a self-closing rotary control element.
- Fig. 1 shows a water fitting 2, which regularly has a cast body as a base body that can be positioned on a washbasin, a cooking table or the like, as can be seen from the circumferential socket or collar below.
- a water line 17 can be carried out, which in the present case is in the manner of a hot water line, ie is set up to deliver water at a temperature above 80°C.
- the outlet of the water fitting 2 is attached above and is not illustrated here for the sake of simplicity.
- a mixer cartridge can also be provided which, for example, lines via a single-lever mixer, not shown on the right, through separate water lines, allows the delivery of cold or mixed water.
- a self-closing rotary control element 1 is provided for opening and closing the water pipe 17 , which actuates the rotary control element 6 inside the water fitting 2 .
- the rotatable actuator 6 is positioned in a stationary manner in the water fitting 2 and has a rotating pin on the front side, which is connected to the gripping sleeve S via a screw connection. In other words, it is fundamentally possible, by rotating the gripping sleeve S, to also rotate the rotatable actuator 6 located inside.
- the self-closing rotary control element 1 has an outer gripping sleeve S, which can consist of several components.
- this includes an outer part 4, which forms the outer peripheral surface in the manner of a sleeve and z. B. can be corrugated to ensure a better feel for the operation of the rotary control element 1.
- the outer part 4 can be closed by a cap on the end face. It is possible for the end cap to be in positive engagement with the outer part, but materially bonded connections are also possible, for example.
- the outer part 4 has an opening 7 in the upper area, in which a spring-loaded push button 8 is arranged.
- the push button 8 is pressed from the inside with a single compression spring 16 against the inner surface of the outer part 4 so that the push button 8 essentially completely closes the opening 7 .
- a sliding or pivotable bolt 14 is shown, which is moved if the pressure button 8 against the bias of the compression spring 16 is pressed.
- the compression spring 16 is mounted in a base part 5 lying on the inside. When you press the pushbutton fes 8, it can be moved toward the base part 5, if necessary, until it touches it or comes to rest there. It is possible that the latch 14 interacts with (different) areas of the base part 5 both in the non-depressed position and in the engaged position of the push button 8 .
- the outer part 4 and the base part 5 can be rotated together relative to an inner part 13 which is fixed directly to an outer, stationary housing part of the actuator 6 . occurs Such a relative rotation, then the torsion spring 10 ensures that an actuating force S is generated, which builds up a return adjustment or counterforce, so that the grip sleeve S is constantly moved back into the closed position G when released.
- a base part 5 is shown, on or on which the spring-loaded push button 8 is mounted. Also provided here is a bolt 14 that can be pivoted about an axis and has a section that extends radially between the push button 8 and the base part 5 . On the opposite side relative to the pivot axis, the bolt 14 has a kind of hook or grid that can interact with a first rotation limiter 11, which is shaped like a bolt recess 15 in the inner part 13 located further inside or adjoining it. For this purpose, the base part 5 has an opening. So if the push button 8 is not pressed, the bolt 14 is locked in the underlying bolt recess 15 (Ge closed position G).
- Fig. 3 shows that the bolt 14 can not only extend in the circumferential direction of the base part 5 or is positioned in a receptacle provided for this purpose, but also axially thereto, in which case the individual compression spring 16 is adjacent to the opening towards the inner part 13 between a portion of the bolt 14 and the base part 5 is positioned.
- the push button 8 is mounted in the base part 5 in such a way that it is positioned on this part of the bolt 14 under which the compression spring 16 is located. This enables the push button 8 and the bolt 14 of the rotary locking mechanism 9 to be actuated by an individual compression spring 16 .
- first rotation limiter 11 and the second rotation limiter 12 in the circumferential direction defines the maximum pivoting range of the grip sleeve, which is preferably in the range from 40 angular degrees to 180 angular degrees.
- the inner part 13 is shaped in such a way that the bolt 14 is locked in the closed position G illustrated here is and can be pivoted against the spring force of the individual compression spring 16 and then in the circumferential direction by Rich up to the second rotation limiter 12 in the inner part 13 is displaceable. If this adjusting movement is carried out by an operator, the torsion spring 10 attached indirectly to the housing section 19 in the abutment 18 (here in the inner part 13) is simultaneously further tensioned, so that an adjusting force S is generated in this way, which causes the rotary actuator 1 to close automatically. when the grip sleeve is released again.
- the other abutment 18 of the torsion spring 10 can be provided in the base part 5, which is not provided here for illustration purposes.
- a hot water faucet 2 which has a single-lever mixer on one side and a self-closing rotary control element 1 on the opposite side.
- the operation is carried out in such a way that first the spring-loaded push button 8 must be pressed radially inwards, so that it is moved, starting from the opening 7 of the outer part 4, into the inner areas. Then, a rotation movement is allowed because the rotation lock mechanism 9 is thus released. If the rotation is then carried out starting from the closed position G, a blind pivoting range 20 initially follows for at least 20 angular degrees, preferably between 20 and 30 angular degrees. During this adjustment path or this rotation, the rotatable actuator does not yet open the water pipe.
- the opening of the water pipe starts only after this blind swivel range 20 has been exceeded up to the open position ung O. As long as the grip sleeve 3 is actively held in this open position, hot water will continue to be dispensed. If the grip sleeve 3 released, the actuating force generated by the integrated torsion spring 10 causes the turning handle to return to the closed position G.
- a self-closing rotary control element for a water fitting was thus specified, which only allows a water path to be released with the aid of complex movement and/or handling sequences. This can be used as an effective child safety device, making it difficult to operate the water fitting.
