Description

[0001] The invention relates to a rod-mountable holder comprising a holding body designed for attachment to a rod, which can in particular be a holder for a sanitary hand shower. In the latter case, the holding body can be mounted on a hand shower rod in a movable or fixed manner.

[0002] Various conventional rod-mountable, ie designed and configured for mounting on a rod, holders of this type, in particular in the form of hand shower holders, are disclosed, for example, in the patent specifications EP 0 965 699 B1, DE 23 42 613 B2, EP 2 703 569 B1, EP 0 733 747 B1 and US 8,448,270 B2 as well as the published patent applications DE 103 03 169 A1, EP 1 921 214 A1, WO 2011 / 088763 A1 and DE 10 2010 063 968 A1.

[0003] In a widely used type of such holder, the holding body is designed for displaceable attachment to a rod and has a rod through-opening for the rod, wherein the holder further comprises a clamping unit movable between a clamping position and a release position, which, when the holding body is attached to the rod, in the release position allows a displacement of the holding body along the rod and in the clamping position exerts a clamping force which blocks a displacement of the holding body along the rod, and an operating unit for user-operated movement of the clamping unit between its clamping position and its release position. Thus, a user can, if necessary, by appropriately operating the operating unit, the holder, which e.g.when used as a hand shower holder, has suitable means for holding a hand shower, preferably detachably, from its clamping position on the rod, moving it along the rod and returning it to its clamping position on the rod at the new rod position.

[0004] German Patent Application DE 10 2015 226 624 A1 discloses such a handheld shower holder, in which the clamping unit is formed by two clamping jaws that can be elastically expanded from a clamping gap-reducing clamping position to a clamping gap-increasing sliding position. These clamping jaws at least partially encompass the support rod and define a clamping gap between them. A wedge element of the operating unit can extend displaceably into the clamping gap. The clamping jaws can be pretensioned into the clamping position by means of an elastic element or, alternatively, can be inherently elastic or resilient.

[0005] Another such hand shower holder is disclosed in patent JP 4-879034 B2. In this hand shower holder, the clamping unit comprises a helical compression spring, which, in a constricted state, provides the clamping position of the clamping unit. In a contrastingly expanded state, into which it can be moved by axial compression, it provides the release position of the clamping unit. For axial compression of the helical compression spring, the associated operating unit has two axially spaced sliding blocks, which the user can move toward each other in the axial direction using associated lever-shaped handles.

[0006] Hand shower holders of the type mentioned above are already in use in various ways and can be mounted on a hand shower rod. The holder body of said holder comprises a rod holding part that can be mounted displaceably or non-displaceably on the hand shower rod, a shower holding part for holding the hand shower, and a rotary coupling by means of which the shower holding part is coupled to the rod holding part so that it can rotate relative to the latter at least in a first direction of rotation, and optionally additionally in a second direction of rotation opposite to the first. The rod holding part can, for example, have a rod feed-through opening through which the rod extends when the holder is mounted. The shower holding part can, for example, have a receptacle for removably receiving the hand shower, specifically a hand shower body thereof or a hand shower hose connected to the hand shower.The shower head holder can be rotated by the user if necessary in order to reorient the hand shower attached to it.

[0007] The invention is based on the technical problem of providing a rod-mountable holder of the type mentioned at the outset, which offers advantages over conventional holders with regard to functionality, ease of use and / or manufacturing effort.

[0008] The invention solves this problem by providing a rod-mountable holder with the features of claim 1 or 9. Advantageous further developments are specified in the subclaims.

[0009] According to the invention, the rod-mountable holder comprises a holding body configured for slidable attachment to a rod, having a rod passage for the rod, a clamping unit movable between a clamping position and a release position, which is formed by a wrap spring unit that wraps around the rod passage opening and, when the holding body is attached to the rod, allows displacement of the holding body along the rod in the release position and exerts a clamping force in the clamping position that blocks displacement of the holding body along the rod, and an operating unit for user-actuated movement of the clamping unit or wrap spring unit between its clamping position and its release position. The wrap spring unit comprises a wrap spring that wraps around the rod passage opening over more than 360°.The respective wrap spring can be moved at both ends by the operating unit between a constricting state, which provides the clamping position of the clamping unit, and an expanding state, which provides the release position of the clamping unit. For this purpose, the operating unit preferably interacts with one or both ends of the wrap spring. The operating unit acts on one or both ends of the respective wrap spring to move it from its constricting to its expanding state, thereby causing a spreading movement of the ends of the respective wrap spring with a main directional component tangential to the respective wrap spring.

[0010] The tangential direction refers to the direction tangential to the wrap / circumferential direction of the wrap spring, while the radial direction refers to the direction perpendicular to this direction, transverse to the longitudinal center axis of the wrap spring. The term "main direction component" refers to the fact that the actual direction of the push-button or wrap spring movement in question does not necessarily correspond exactly to this radial or tangential direction; however, the directional component of the movement in this direction is greater than in the direction perpendicular to it. The wrap spring in question can be spread open by operating the control unit in order to release or at least reduce its clamping force, thereby moving it from its clamped position to its released position.

[0011] The bracket equipped with this clamping unit requires comparatively little manufacturing effort and possesses very favorable functional properties with regard to its releasably clamped fixation to a rail. It is particularly suitable as a bracket for a sanitary hand shower or a corresponding hand shower body on a hand shower rail, e.g., in a shower room, where it can be used in the usual way to hold the hand shower body in a height-adjustable manner or, in the case of corresponding side showers, to slide it along a horizontal hand shower rail. The special clamping unit in the form of a wrap spring unit enables, on the one hand, a secure fixation of the bracket to the rail in its clamped position and, on the other hand, a sufficiently smooth movement of the bracket along the rail in its release position.

[0012] The wrap spring unit offers many degrees of freedom to adjust the clamping behavior of this clamping unit, both in the clamping position and in the release position, in the best possible way for the respective application. This includes, for example, the selection of the wrap angle, i.e. over how many degrees or in how many turns / coils the wrap spring unit wraps around the rod feedthrough opening, the selection of the spring material for the one or more wrap springs, the selection of the number of wrap springs arranged next to each other, the selection of the diameter of the coils / coils as well as the cross-sectional area and cross-sectional shape of a spring material used for the respective wrap spring. If required, the wrap spring unit can, for example,be designed in such a way that in the release position it still provides a slight clamping force that can be easily overcome by the user, so that the holder on a vertical pole does not accidentally fall down when the user actuates the control unit to release the clamp. In addition, such a suitable design of the wrap spring unit can easily ensure that the force required by the user to move the holder changes only slightly depending on the surface condition of the pole, e.g. dry, damp or oily. By using leg spring units with different winding diameters, the holder can also be adapted to different diameters of the pole to be passed through without great effort.

[0013] Due to the design with the wrap spring that wraps around the rod bushing over more than 360°, the clamping force acting on the rod is distributed relatively evenly over the entire rod circumference, which can also have a positive effect on the clamping behavior.

[0014] In a further development of the invention, the wrap spring unit comprises a plurality of wrap springs arranged next to one another in the longitudinal axis direction of the rod feedthrough opening, each of which wraps around the rod feedthrough opening by more than 180°. In this embodiment with a plurality of wrap springs arranged next to one another in the longitudinal axis direction of the rod feedthrough opening, the clamping force in the clamping position as well as an optionally remaining, slight clamping force in the release position can be adjusted or changed as desired by selecting an appropriate number of wrap springs. The arrangement of the plurality of wrap springs also increases functional reliability and failure safety, since the intended clamping function can still be adequately ensured by the remaining wrap spring(s), e.g. in the event of a wrap spring breaking.In corresponding implementations, the wrap spring unit comprises a combination of several wrap springs arranged next to one another in the longitudinal axis direction of the rod passage opening, of which one or more or even all wrap springs wrap around the rod passage opening over more than 360°.

[0015] In a further development of the invention, the multiple wrap springs arranged side by side in the longitudinal axis of the rod passage opening are in contact with each other, thus forming a wrap spring assembly. This can offer structural and functional advantages.

[0016] In a further development of the invention, the wrap spring unit comprises a wrap spring that wraps around the rod passage opening by more than 720°, i.e., this wrap spring surrounds the rod passage opening in two or more turns or coils. This can also offer structural and functional advantages. For example, this wrap spring can then be made of weaker wire material and still provide a comparable clamping force to a wrap spring made of stronger wire material that only wraps around the rod passage opening by up to 360° or in any case in fewer than two turns.If the wrap spring in the usual helical spring form wraps around the rod feedthrough opening in more turns, this also widens the possible contact surface between the wrap spring unit and the rod passed through the opening, which can also be advantageous for the clamping behavior of the clamping unit.

[0017] In a further development of the invention, the two ends of the respective wrap spring are located on the same side with respect to the rod feedthrough opening. This can facilitate or simplify the coupling of the wrap spring unit to the control unit, especially when the control unit interacts with the ends of the wrap spring unit.

[0018] In a further development of the invention, the constricting state of the respective wrap spring is its initial state, to which the wrap spring automatically returns from the expanded state through its own elasticity. This means that the wrap spring unit is pre-tensioned into its clamping position. Using the control unit, the user can move the wrap spring unit into the release position, and after this actuation by the user, the wrap spring unit can automatically return to its clamping position.

[0019] In a further development of the invention, the operating unit is a push-button unit with a push button acting on the wrap spring unit. This provides a convenient operating experience for the user in certain applications. For example, the user can safely operate the operating unit with just one finger and, if necessary, grasp the holder with the remaining fingers and move it along the rod.

[0020] In one embodiment of this operating variant, the push button is movably arranged with a radial main directional component relative to the respective wrap spring, and an associated push button-toggle coupling or push button guide ensures that the movement of the push button in this direction is translated into the spreading movement of the ends of the respective wrap spring with a tangential main directional component relative to the respective wrap spring. In this embodiment, the respective wrap spring can therefore be spread open by actuating the push button, which, as usual, is a transverse actuating movement, in order to release or at least reduce its clamping force.

[0021] In an alternative development of the invention, the operating unit is a rotary knob unit with a rotary knob acting on the wrap spring unit. This design can also be advantageous for corresponding applications and, if necessary, enable one-handed operation of the holder. It can be constructed comparatively compactly, even if a longer actuation path is required to move the wrap spring unit from the clamped position to the release position, since the actuation path in this case is determined by the angle of rotation of the rotary knob and the angle of rotation generally does not need to increase the size. With a longer actuation path, the actuation force required to overcome the clamping force of the wrap spring unit can be reduced if necessary.Depending on requirements, the rotary knob variant can be designed so that the rotary knob can only be turned in one direction of rotation or alternatively in one direction and in the opposite direction of rotation in order to move the clamping unit into its release position.

[0022] In one embodiment of this operating variant, the rotary knob is arranged to be movable around a rotational axis with a radial main directional component relative to the respective wrap spring. An associated rotary knob guide ensures that the rotary movement of the rotary knob is translated into the spreading movement of the ends of the respective wrap spring with a tangential main directional component relative to the respective wrap spring. Thus, in this case, turning the rotary knob can in turn spread the wrap spring, thereby moving the wrap spring unit from its clamping position to its release position.

[0023] In a further development of the invention, the holder includes an open, elastic clamping sleeve which defines the rod feedthrough opening. The wrap spring unit wraps around the clamping sleeve. Because the clamping sleeve is open and elastic, it can contract and thereby press on the rod through which it is passed when the wrap spring unit moves into its constricting state. With the clamping sleeve, the clamping force of the wrap spring unit can be transferred very evenly to the rod if necessary due to the associated increase in the contact area with the rod. In addition, it can be used to avoid direct contact between the one or more wrap springs and the rod if necessary, so that, for example, when choosing the material for the wrap spring unit, no consideration needs to be given to the material or surface of the rod.By using clamping sleeves with different diameters, it is possible to easily adapt to different diameters of the rod to be passed through if necessary.

[0024] According to a further aspect, the invention relates to a rod-mountable holder which is designed for use with a sanitary hand shower and for this purpose has a corresponding holding body for attachment to a hand shower rod. The holding body comprises a rod holding part which can be mounted on the hand shower rod, a shower holding part for holding the hand shower and a rotary coupling by means of which the shower holding part is rotatably coupled to the rod holding part relative thereto at least in a first direction of rotation, optionally additionally in a second direction of rotation opposite to the first. The rod holding part allows the hand shower, i.e. a corresponding hand shower body, to be held displaceably or non-displaceably on the hand shower rod as required.The rotary coupling comprises a wrap spring unit which wraps around a coupling socket formed on the rod holding part, providing a torsional resistance force over more than 180°, and is rotationally coupled to the shower holding part.

[0025] This specific rotary coupling implements a functionally advantageous, rotatable connection of the shower head holder to the rod holder in a structurally simple manner. The manufacturing effort for the coupling socket on the rod holder and for the wrap spring unit can be kept to a minimum, and the wrap spring unit, which wraps around the coupling socket over more than 180°, allows the torsional resistance force—that is, the force that the rotary coupling, via the wrap spring unit, applies to counteracting rotation of the shower head holder on the rod holder—to be provided in the desired manner and magnitude.

[0026] Analogous to the wrap spring unit for the clamping unit mentioned above, there are again many degrees of freedom for setting the desired size or strength of the torsional resistance force for the respective application.As already mentioned, this concerns, among other things, the cross-sectional thickness and cross-sectional shape of a spring wire material used for the wrap spring unit, the winding diameter and the number of turns of the wrap spring unit wrapping around the coupling socket, wherein here too the wrap spring unit can consist of a single wrap spring or of several wrap springs, preferably arranged next to one another in a longitudinal axis direction of the coupling socket, wherein in the latter case each wrap spring can wrap around the coupling socket by more than 180° or alternatively one, several or all wrap springs wrap around the coupling socket by a maximum of 180° such that the wrap spring unit formed by the several wrap springs wraps around the coupling socket over a total of more than 180°.

[0027] Depending on the application, the twist coupling can be designed accordingly by means of a corresponding design of the wrap spring unit so that it only allows the shower head holder to rotate relative to the bar holder in the first direction of rotation or, alternatively, in the opposite second direction of rotation. In the latter case, the wrap spring unit can be designed, as required, so that an approximately equal torsional resistance force is achieved for both directions of rotation or, alternatively, a higher torsional resistance force is achieved for one direction of rotation than for the other. This particularly includes the frequently desired application in which the shower head holder can be rotated relatively easily in one direction and more difficultly in the other direction, i.e.In this case, the torsional resistance force or synonymously the torsional moment is provided by the wrap spring unit for the two directions of rotation in significantly different sizes or strengths.

[0028] In a further development of the invention, the wrap spring unit is formed by a wrap spring that wraps around the coupling piece over more than 360° between a first and a second spring end. This wrap spring is coupled to the shower head holder at only one of its two ends in a rotationally fixed manner in both directions of rotation, or alternatively, it is coupled to the shower head holder at one end only in the first direction of rotation and at the other end only in the second direction of rotation. This represents advantageous implementations of the coupling of the wrap spring unit to the shower head holder, adapted to the respective requirements.

[0029] In the variant in which one spring end is coupled to the shower head holder in both directions of rotation, the other spring end is preferably free, and the wrap spring is pulled along, contracting slightly when the shower head holder is rotated in one direction, and expanding slightly when rotated in the other direction. Depending on how the wrap spring is wound around the coupling socket, the wrap spring rotates with the shower head holder, generally providing a higher torsional resistance in the tightening direction of rotation than in the expanding direction of rotation, which, as mentioned above, is desirable in many cases.Alternatively, the design can be selected in such a way that the wrap spring blocks in the closing direction, either because it is fixed to the rod holding part with its other spring end or because it blocks due to frictional engagement with the coupling socket, although its other spring end is free.

[0030] If the wrap spring is coupled to the shower head holder at both ends in one or the other direction of rotation, it can be driven symmetrically with the shower head holder in both directions of rotation, e.g. by slightly expanding in each case, whereby a variant with the same torsional moment, ie the same torsional resistance force, can be realized for both directions of rotation if required.

[0031] In a further development of the invention, the rod holder has a rod through-hole, and the wrap spring unit for the rotary coupling of the shower head holder and the rod holder is arranged with a spring longitudinal axis running perpendicular to a longitudinal axis of the rod through-hole. This enables a structural design of the holder that is advantageous in many cases.

[0032] In a further development of the invention, the aspects of the specific rotary coupling between the shower head holder and the rod holder and the specific clamping unit for the releasable clamping of the holder body to the rod are combined, i.e. the holder has the features of both one of claims 1 to 8 and the features of one of claims 9 to 10. Accordingly, the functional and design properties and advantages mentioned above in relation to these aspects are combined in this holder according to the invention. This combined holder can also be constructed comparatively compactly. It can be reliably clamped to a rod and moved along the rod by user-actuated release of the clamp. The shower head holder, if necessary with the hand shower body held to it, can be easily rotated relative to the rod holder, with which the holder is held clamped to the rod.

[0033] Advantageous embodiments of the invention are illustrated in the drawings. These and other embodiments of the invention are explained in more detail below.

[0034] The Fig. 1 to 10 and 14, includes a holding body 1 that is configured for displaceable attachment to a rod and has a rod through-opening 2 for the rod. The holding body is shown mounted on a rod 3, which may be, for example, a handheld shower rod, i.e., a rod intended for arranging a sanitary handheld shower. Furthermore, the holding body includes a clamping unit 4 that is movable between a clamping position and a release position. When the holding body 1 is attached to the rod 3, in the release position, this clamping unit allows displacement of the holding body 1 along the rod 3 and, in the clamping position, exerts a clamping force that blocks displacement of the holding body 1 along the rod 3. For user-actuated movement of the clamping unit 4 between its clamping position and its release position, the holding body includes an operating unit 5.

[0035] The clamping unit 4 is formed by a wrap spring unit 6 that wraps around the rod passage opening 2. In the embodiment according to the Fig. 1 to 6 and 14, the wrap spring unit 6 includes a wrap spring 7 which wraps around the rod passage opening 2 over more than 360°, wherein the wrap spring 7 is movable by the operating unit 5 between a narrowing state providing the clamping position of the clamping unit 4 and an expanding state providing the release position of the clamping unit 4.

[0036] The wrap spring 7 therefore wraps itself around the rod passage opening 2 by more than one complete winding or turn, whereby the clamping force can act along the entire circumference of the rod passage opening 2 and thus along the entire circumference of the rod 3. Optionally, the wrap spring 7 wraps itself around the rod passage opening 2 by more than 720°, ie over more than two windings / turns. In the examples shown, the Fig. 1 to 6 and 14, it wraps around the rod passage opening 2 over more than two and slightly less than three full turns / coils. With a larger wrap angle or a larger number of turns / coils of the wrap spring 7 around the rod passage opening 2, the effective contact area for the clamping force can be increased if necessary, or a weaker spring material can be used for the wrap spring 7 to achieve the same required clamping force.

[0037] The wrap spring ends with two ends 7a, 7b, which in corresponding designs, as in the example shown, are located on the same side with respect to the rod passage opening 2, in the Fig. 1 to 4 of the left side of the rod passage opening 2.

[0038] In corresponding versions, as in the examples shown, the Fig. 1 to 10 and 14, the narrowing state of the wrap spring unit 6 or the wrap spring 7 is an initial state thereof, into which the wrap spring 7 automatically returns from the expanding state in a self-elastic manner.

[0039] In corresponding embodiments, the operating unit 5 is as shown in the examples of Fig. 1 to 9 and 14 a push-button operating unit or short push-button unit 8 with a push button 8a acting on the wrap spring unit 6. In alternative embodiments, the operating unit 5 is as in the example shown by Fig. 10 a rotary knob operating unit or briefly rotary knob unit 9 with a rotary knob 9a acting on the wrap spring unit 6.

[0040] In the push-button variant, the push-button 8a is arranged to be movable in corresponding designs, as in the example shown, with a radial main direction component Tk relative to the wrap spring 7. Specifically, if necessary, as in the example shown, the transverse movement of the push-button 8a can be parallel to the radial direction of the wrap spring 7, which in turn is perpendicular to the longitudinal center axis of the helical spring-shaped wrap spring 7.

[0041] In the execution according to the Fig. 1 to 9, a push-button guide 10, as a coupling means between the push-button unit 8 and the wrap spring unit 6, translates the transverse movement of the push-button 8a into a spreading movement of the ends 7a, 7b of the wrap spring 7, wherein the spreading movement of the wrap spring ends 7a, 7b occurs with a tangential main directional component with respect to the wrap spring 7. The tangential direction is perpendicular to the radial direction and to the longitudinal center axis of the wrap spring 7. For this purpose, the push-button guide 10 can, for example, include an inclined surface guide track on the push-button 8a, along which the wrap spring ends 7a, 7b slide.

[0042] Optionally, the push button unit 8 further comprises a return spring 11 to effect or assist in returning the push button 8a to its original position. In the example shown, the push button 8a is pressed by the user in the direction into the holding body 1, whereby it spreads the wrap spring 7 via the push button guide 10. The wrap spring 7 is thereby moved from its constricting state, which clamps the holding body 1 to the rod 3, to its expanding state, in which it allows the holding body 1 to be moved along the rod 3. When released, the push button 8a returns to its original position under the action of the return spring 11 and possibly a supporting effect of the wrap spring 7, which is inherently elastically pretensioned to its constricting initial state, so that the wrap spring 7 can once again assume its constricting clamping position.

[0043] In the rotary knob variant according to Fig. 10, the rotary knob 9a is rotated about a rotation axis D A arranged to be rotatable, which has a radial main direction component Dk with respect to the wrap spring 7. Preferably, the direction of the rotation axis D A parallel to the radial direction of the wrap spring 7. The direction of the rotation axis D AIn the rotary knob variant, for example, it can be parallel to the transverse direction of movement of the push button 8a of the push button variant. A rotary knob guide translates the rotary movement of the rotary knob 9a into a spreading movement of the wrap spring ends 7a, 7b, by which the latter spread with a main directional component tangential to the wrap spring 7, i.e. the wrap spring spreading movement corresponds to the spreading movement of the wrap spring 7 explained above for the push button variant. Any suitable implementation can be used for the rotary knob guide, as is familiar to those skilled in the art, which therefore needs not be shown or explained further here. For example, the rotary knob 9a can have an inclined surface guide track extending in the circumferential direction, along which the wrap spring ends 7a, 7b slide.

[0044] In the aforementioned embodiments, the operating unit 5 acts on both ends 7a, 7b of the wrap spring 7 to place it in its expanded, spread state. In alternative embodiments, the operating unit 5 acts only on one end of the wrap spring 7, while the other leg spring end is held stationary, e.g., at a corresponding attachment point of the holding body 1. In these alternative embodiments, the two leg spring ends 7a, 7b can be located on the same side or on different sides of the rod passage opening 2.

[0045] In corresponding embodiments, the holder includes, as in the examples shown, the Fig. 1 to 10 and 14, an open, elastic clamping sleeve 12 defining the rod passage opening 2, around which the wrap spring unit 6 or the wrap spring 7 wraps. Since the clamping sleeve 12 is open, i.e., has a circumferential gap 12a, it can follow the narrowing or widening movement of the wrap spring unit 6 around the rod passage opening 2 when the wrap spring unit 6 or wrap spring 7 wrapping around the clamping sleeve 12 narrows to form a clamping connection or widens to release the clamping connection. In this case, the clamping sleeve 12 transfers the clamping force of the wrap spring unit 6 to the rod 3 in the rod passage opening 2. The wrap spring unit 6 then does not need to come into contact with the rod 3. The clamping sleeve 12 is made of a suitable elastic plastic or metal material and fits around the rod 3 with contact.In alternative designs, the wrap spring unit 6 wraps directly around the rod 3 with contact without the clamping sleeve 12 inserted between them.

[0046] In corresponding embodiments, the holding body 1 has, as shown, a cylindrical shape with a longitudinal axis direction L S the rod passage opening 2 vertical cylinder longitudinal axis.

[0047] The Fig. 7 to 9 illustrate a rod-mountable bracket that can be used in any of the above-mentioned Fig. 1 to 6 and 14, the only difference being an alternative design of the wrap spring unit 6. Furthermore, reference can be made to the above explanations of the corresponding embodiments, which apply to the variant of the Fig. 7 to 9 apply accordingly.

[0048] Specifically, the wrap spring unit 6 in the embodiment of the Fig. 7 to 9 several, in a longitudinal axis direction L SThe rod passage opening 2 has wrap springs 71, 72, 73 arranged next to one another, each of which wraps around the rod passage opening 2 by more than 180°, wherein the respective wrap spring 71, 72, 73 can be moved by the operating unit 5 between a constricting state providing the clamping position of the clamping unit 4 and an expanding state providing the release position of the clamping unit 4. Preferably, as in the example shown, the plurality of wrap springs 71, 72, 73 abut one another with touching contact and thus form a wrap spring assembly. In the example shown, the wrap spring assembly consists of the three wrap springs 71, 72, 73; in alternative embodiments, it consists of two or four or more individual wrap springs.Such a realization of the wrap spring unit 6 from several wrap springs can increase the reliability in that if one of the wrap springs breaks, the remaining, still intact wrap springs can take over or continue to ensure the clamping function.

[0049] In the example shown, each of the wrap springs 71, 72, 73 wraps around the rod passage opening 2 over an angle of approximately 310° to 320°, in alternative embodiments over an angle between 180° and 310° or over an angle of more than 320°. In particular, in alternative embodiments, at least one of the wrap springs can wrap around the rod passage opening 2 over more than 360°. In the example shown, the wrap springs 71, 72, 73 are each arranged next to one another with their two spring ends 7a, 7b synchronously, i.e. in the same position in the circumferential direction. This generally simplifies the spreading of the wrap springs 71, 72, 73 by the operating unit 5. In alternative embodiments, at least two of the wrap springs are arranged with spring ends offset from one another in the circumferential direction. This can be done, for example, if required.be used to wrap the rod passage opening 2 around the entire circumference of the opening by the wrap spring unit 6, even if each of the wrap springs forming the wrap spring unit 6 or the wrap spring package only wraps around the rod passage opening 2 by less than 360°.

[0050] The user-operated movement of the clamping unit 4 formed by this wrap spring unit 6 by the plurality of individual wrap springs 71, 72, 73 between its clamping position and its release position is carried out by the operating unit 5 in the push-button variant or the rotary knob variant in the same way as explained above for the wrap spring unit 6 formed by the wrap spring 7. By pressing the push-button 8a of the push-button unit 8 or turning the rotary knob 9a of the rotary knob unit 9, the wrap springs 71, 72, 73 are moved together from their constricting state to their expanding state, wherein the constricting state is preferably again an initial state of the respective wrap spring 71, 72, 73, to which it automatically returns from the expanding state due to its own elasticity. By releasing the push-button 8a orIn this case, by turning the rotary knob 9a back or further, the wrap spring assembly of the wrap springs 71, 72, 73 returns to the narrowing clamping state.

[0051] The Fig. 11 to 13 illustrate a rod-mountable holder for a sanitary hand shower, the holder comprising a holding body 1' for attachment to a hand shower rod 3' and the Fig. 11 to 13 show the holder or the holding body 1' in the mounted state on the hand shower rod 3'. The holding body 1' includes a rod holding part 1a mountable on the hand shower rod 3', a shower holding part 1b for holding the hand shower, and a rotary coupling 1c, by which the shower holding part 1b is coupled to the rod holding part 1a so as to be rotatable relative thereto in a first direction of rotation DR1 and / or in a second direction of rotation DR2 opposite to the first. The two opposite directions of rotation DR1, DR2 can in particular be clockwise or counterclockwise rotations about a rotation axis which, when the holder 1' is mounted on the rod 3', runs perpendicular to a longitudinal axis of the rod 3'.

[0052] In the Fig. 12 and Fig. 13, with the shower head holder 1b omitted, it can be seen that the rotary coupling 1c includes a wrap spring unit 13 which wraps around a coupling socket 14 formed on the rod holder 1a, providing a torsional resistance force for the torsional movement of the shower head holder 1b relative to the rod holder 1a over more than 180°, and is rotationally coupled to the shower head holder 1b. Furthermore, the rotary coupling 1c is designed in a conventional manner (which will therefore not be explained further here) such that the shower head holder 1b is rotatably held on the rod holder 1a. Specifically, the rotary coupling 1c can be designed such that the rotation of the shower head holder 1b relative to the rod holder 1a can be achieved continuously as required, or alternatively with traversable locking steps.The twisting resistance force counteracts a twisting movement exerted by the user on the shower holder part 1b with a desired resistance that can be overcome by the user and secures the shower holder part in its current rotational position against undesired automatic twisting, for example due to the weight of a hand shower held by the shower holder part.

[0053] In advantageous embodiments, the wrap spring unit 13 is formed, as in the example shown, by a wrap spring 15 that wraps around the coupling socket 14 between a first spring end 15a and a second spring end 15b over more than 360°. Depending on requirements and application, the wrap spring 15 is coupled to the shower head holder part 1b in a rotationally fixed manner at only one of its two spring ends 15a, 15b in both directions of rotation DR1, DR2, or alternatively, it is coupled to the shower head holder part 1b in a rotationally fixed manner at the first spring end 15a only in one of the two opposite directions of rotation and at the second spring end 15b only in the other of the two opposite directions of rotation. Fig. 12, a round wire material is used for the wrap spring 15. The Fig. The variant shown in Figure 13 differs from the one in Fig. 12 in that a square wire material is used for the wrap spring 15.

[0054] In advantageous embodiments, the rod holding part 1a has a rod passage opening 2, and the wrap spring unit 13 is provided with a perpendicular to a longitudinal axis direction L S the rod passage opening 2 extending spring longitudinal axis L F The spring longitudinal axis L F In advantageous embodiments of the holder, the wrap spring unit 13 coincides with the axis of rotation about which the shower holder part 1b can be rotated in the first and / or second direction of rotation DR1, DR2 relative to the rod holder part 1a, or runs parallel and offset thereto.

[0055] In the example shown, the wrap spring 15 is only rotationally fixedly coupled to the shower head holder 1b at the first spring end 15a, which is axially angled for this purpose, in both directions of rotation DR1, DR2, while its other, second spring end 15b is free. For the rotationally fixed coupling of the first spring end 15a, the shower head holder 1b has a conventional receptacle (not shown in detail here), into which the first spring end 15a is inserted in such a way that it is driven by the rotational movement of the shower head holder 1b in both directions of rotation DR1, DR2. In one of the two directions of rotation, the wrap spring 15 is thereby driven by contracting slightly; when rotated in the opposite direction, it is driven by expanding slightly. Thus, in the contracting direction of rotation, it bears slightly more against the coupling socket 14 around which it wraps than in the expanding direction of rotation.

[0056] The movement of the wrap spring 15 in the tightening direction of rotation generally results in a somewhat higher frictional resistance for the rotation of the wrap spring 15 around the coupling socket 14 compared to the expanding direction of rotation, and a somewhat higher torsional moment of the wrap spring 15, which overall leads to a somewhat higher torsional resistance force of the wrap spring 15 on the shower head holder 1b compared to the rotation of the wrap spring 15 in the expanding direction of rotation. This results in an asymmetrical torsional resistance force, which is desirable in many cases and is noticeably greater when the shower head holder 1b is rotated in one direction of rotation than when it is rotated in the other direction.

[0057] Depending on the requirements and application, the rotary coupling 1c is designed such that the wrap spring unit 13 or the wrap spring 15 on the coupling socket 14 does not close or tighten in a blocking manner when rotated in the closing direction, but rather rotates with the shower head holder 1b after a short closing stroke. In alternative designs, the wrap spring unit 13 or the wrap spring 15 can lock in the closing direction, which then prevents the shower head holder 1b from being rotated further in the closing direction.

[0058] In alternative embodiments not shown, the shower head holder 1b engages the wrap spring unit 13 or the wrap spring 15 at one spring end in one direction of rotation and at the other spring end in the other direction of rotation. For this purpose, the two spring ends 15a, 15b are rotationally coupled to the shower head holder 1b in one of the two opposite directions of rotation DR1, DR2, while remaining free in the other direction of rotation. This can be achieved, for example, by corresponding stops on the shower head holder 1b, which strike the facing spring end 15a, 15b in only one of the two directions of rotation DR1, DR2 and engage it in the respective direction of rotation.

[0059] The Fig. The bracket with the holding body 1' explained in Figures 11 to 13 is designed in corresponding versions for displaceable or alternatively non-displaceable attachment to the rod 3'. In the implementation with the holding body 1' displaceably attachable to the rod 3', the holding body 1' can be identical to the holding body 1 of the Fig. 1 to 10 and 14. The holding body 1' then accordingly contains the clamping unit 4 in the form of the wrap spring unit 6 as well as the operating unit 5. In other words, the holding body 1 in this case contains the rod holding part 1a, the shower holding part 1b and the rotary coupling 1c with the associated wrap spring unit 13. In this case, the rod holding part 1a has the rod feedthrough opening 2, through which the rod 3 extends when the holding body 1 is mounted, along which the holding body 1 can be moved.

[0060] In other words, in this advantageous implementation of the holder according to the invention, the aspect of the longitudinal displacement of the holder or its holding body along a rod and its releasable fixability to the rod by the associated clamping wrap spring unit 6 and the aspect of the mounting of a sanitary hand shower on a rod by means of the holding body with rod holding part and relative rotatable shower holding part using the rotary coupling having the associated wrap spring unit 13 are combined. Fig. 1 to 14, this optional combination implementation of the invention is represented by the fact that those components which can be implemented identically or are at least functionally equivalent are marked with the same reference numerals, both for the embodiment variants according to the Fig. 1 to 10 and 14 as well as for the variants according to the Fig. 11 to 13.

[0061] In corresponding versions of this combination variant, the operating unit 5 is arranged on the rod holder 1a, as shown, and in alternative versions, on the shower holder 1b. Specifically, in corresponding versions, the operating unit 5 and the shower holder 1b are arranged on opposite sides of the holder body 1, 1' with respect to the rod feedthrough opening 2, which optimizes operating comfort for the user in many applications and favors a compact design of the holder body 1, 1', e.g., in a cylindrical shape.

[0062] To hold the hand shower, the shower holder part 1b has a suitable hand shower holder, which in corresponding designs, as in the example shown, can be a conventional conical hand shower holder 16. The hand shower or, specifically, a hand shower body, e.g., with a handle body section or a connection section for a water-supplying hand shower hose, can be inserted into this hand shower holder 16 from the wider conical end. The section of the hand shower that interacts with the conical hand shower holder 16 can alternatively also be formed by a correspondingly conical connection section of a hand shower hose, to which a hand shower body is connected.

[0063] Fig. 14 illustrates a variant of the mounting of the Fig. 1 to 9, which differs from this in the coupling of the control unit 5 to the wrap spring unit 6. Instead of the rotary knob guide 10, the variant of Fig. 14, the operating unit 5 is connected to the spring ends 7a, 7b of the wrap spring 7 via a toggle lever coupling 17 in order to expand the wrap spring 7 as desired by the pressing movement of the push button 8a. For this purpose, the toggle lever coupling 17 includes a toggle lever arm 18, 19 for each of the two spring ends 7a, 7b, each of which bears against the associated spring end 7a, 7b with one end region 18a, 19a, while their other end 18b, 19b is supported on an associated support section 20, 21 of the holding body 1. The two toggle lever arms 18, 19 are rotatably fixed to one another at their second ends 18b, 19b, forming an associated toggle lever joint.

[0064] A pressure web 22 formed on an inner side of the push button 8a presses against the knee joint, i.e. against the two second ends 18b, 19b of the two toggle lever arms 18, 19, when the push button 8a is pressed by the user in the direction into the holding body 1, whereby the toggle lever arms 18, 19, which are arranged with their longitudinal axes oblique to the transverse actuation direction of the push button 8a, move transversely with their rotationally coupled second ends 18b, 19b, so that the toggle lever arms 18, 19 experience an opposite rotation, by means of which the wrap spring 7 is spread out at its ends 7a, 7b as desired.

[0065] After the push button 8a is released by the user, the push button 8a is moved again in the direction out of the, for example, cylindrical holding body 1, wherein this return movement again takes place automatically under the action of a return spring (not shown here) and / or under the action of the wrap spring 7 pre-tensioned in the direction of the non-spread-open state of its spring ends 7a, 7b.

[0066] As already briefly mentioned above, the bracket can also be Fig. 14 shall be designed so that they are compatible with the bracket in accordance with Fig. 11 to 13 is identical or has additional features. Conversely, the mounting of the Fig. 11 to 13 additionally the features of the mounting of Fig. 14.

[0067] As the embodiments shown and explained above make clear, the invention provides a rod-mountable holder which can be mounted in a very advantageous manner in a slidable and releasably clamped manner on a rod and / or is suitable for attaching a sanitary hand shower to a hand shower rod.
