    Spacer with adjustable length
    The subject invention deals with a device for adjusting the length of a spacer element, comprising an adjusting key and a rotating element, the adjusting key having at least one magnet and the rotating element having at least one counter magnet, the at least one magnet and the at least one counter magnet being arranged around the transmission to enable the rotary movement of the adjusting key on the rotary element by the interaction of the magnet and the counter magnet, and wherein the rotary element is designed as a driver for an actuator of the spacer element, the length of the spacer element in the direction by rotating the actuator with the rotary element in a first direction the axial axis of rotation can be enlarged and the length of the spacer element can be reduced in the direction of the axial axis of rotation by rotating the actuator with the rotary element in a second direction. Furthermore, the present invention relates to a height-adjustable floor element for a damp room device with at least one device according to the invention and a template for positioning an adjustment key.
    Adjusting screws are often used to change or fix a position of an element, for example a cover. The inclination of a base plate, e.g. a shower tray, must be adjustable so that a level adjustment, e.g. for the drainage of shower water. One way of fixing the base plate would of course be to pre-adjust the spacers, whereupon the base plate is inserted by placing it on the spacers. However, this method requires a precise adjustment of the spacers before placing the base plate, which is tedious and time-consuming. If, as usual, four spacers, i.e. one per corner of a rectangular base plate, so if the adjustment is inaccurate, the base plate can easily wobble. Even if wobbling could be avoided due to the precise adjustment, it might be necessary to adjust the inclination of the shower base afterwards, for example to enable the optimal drainage of shower water. It is often common to use more than four spacers due to the desired stable positioning of a base plate. In particular, three spacers are not sufficient, since the base plate can rock or bend in the edge areas under load. In the solution just described, the base plate would also have to be removed for each (new) adjustment of the spacers. Simply removing a stuck base plate itself often proves to be difficult. In addition, removing the base plate, subsequent readjustments and reinserting the base plate means a lot of effort due to unnecessary repetitive work steps.

    If you now want to access the set screws from the outside, gaps, cracks and the like naturally arise on the surface of the element. It is therefore desirable to avoid visible adjustment screws, particularly in the area of hygiene, since the formation of gaps, cracks, etc. enables dirt and bacteria to accumulate on the element and the tightness of the element to be adjusted, i.e. the base plate, is often not guaranteed can be. A smooth, homogeneous surface of the base plate would therefore be desirable.
    US 9,190,198 B2 discloses a device for fixing screws as rotating elements, wherein a magnetic adjusting key is used to fix magnetic screws through a non-magnetic cover. This makes it possible to fix screws without creating gaps caused by the screws that are visible from the outside. However, this only enables fixation and no adjustment of a cover, which may be useful in the field of electronic devices, but is unsatisfactory for the assembly of a base plate. The distance between the magnets of the adjusting key and the screws is not constant. AT 518 276 B1 discloses a device for adjusting the length of a spacer element, by means of an adjusting key which acts on a rotary element via a magnetic force and makes it possible to change the length of the spacer element by turning the adjusting key. No direct contact between the adjusting key and the rotating element is required, so that the length can also be adjusted through non-magnetic substances, for example a plate, located between the adjusting key and the rotating element. However, it cannot be ruled out that the length of the spacer element is adjusted, in particular reduced, after an adjustment, in particular by pressure on the spacer element.
    It is therefore the object of the present invention to provide a device which enables a fixed length of a spacer element to be set securely.
    This object is achieved according to the invention in that a blocking element is provided which can be brought from a locking position into an unlocking position, wherein in the locking position the actuator is prevented from rotating at least in the second direction and / or the first direction and in the unlocking position a rotation of the Actuator in the second direction and / or the first direction is enabled. This can prevent the length of the spacer element from being inadvertently adjusted. Twisting the actuator in the second direction would mean reducing the length, twisting the actuator in the first direction would increase the length. For example, depending on the design, the blocking element provided, if it is in the locking position, can reduce and / or increase the length of the spacer element / 24 2 '
    AT-3982 AT can be prevented. The blocking element can be designed in any way, provided that it can be brought into the locking position and unlocking position described above.
    The rotary element is advantageously connected to the actuator via a positive connection, thereby ensuring the transmission of the rotary movement from the rotary element to the actuator. The positive connection can be formed, for example, by a groove and an associated tongue. The groove or the tongue can of course each be located on the actuator or the rotating element.
    The blocking element can be embodied by depressions and / or elevations running in the radial direction on the rotary element, an engagement element also being provided on the spacer element and the blocking element being in engagement with the engagement element in the locking position. Of course, this means that in the unlocked position, the blocking element is not in engagement with the engagement element. The engaging element can be fixed in place on a component of the spacer element in order to prevent rotation of the actuator in the first and / or second direction by the engagement of the engaging element with the blocking element. “Fixed” here means that the engaging element is not rotated with the rotating element. The engagement element can also be formed from one or more elevations or depressions, which are in engagement in the locked position with at least part of the blocking element.
    In addition, the spacer element can have a threaded sleeve with an internal thread, which is screwed onto an external thread of the actuator, whereby the thread position of the internal thread and external thread changes the length of the spacer element. Of course, it is also conceivable to provide the threaded sleeve with an external thread and the actuator with an internal thread, but this complicates the construction of the spacer element. The internal thread and / or the external thread can of course be provided with a stop which prevents the threaded sleeve, e.g. is erroneously unscrewed from the actuator.
    The engagement element is advantageously attached to the threaded sleeve. Of course, this only makes sense if the threaded sleeve is stationary, ie it does not rotate with the rotating element. In the locking position, the engagement of the engagement element with the blocking element can prevent the actuator from rotating in the first and / or second direction. It is particularly advantageous here if the engagement element is formed from one or more elevations or depressions. The threaded sleeve can furthermore have an opening on an upper side facing the adjusting key into which the rotating element is inserted. This is particularly advantageous if there is a positive connection between the rotary element and the actuator and the actuator has an external thread / 24 3 '
    AT-3982 AT. The threaded sleeve can be made as one part or also in several parts, preferably in two parts.
    The blocking element can be formed by saw teeth running on the rotating element in the radial direction with flanks rising in the tangential direction. Since the first direction and the second direction are considered to be tangential, depending on the orientation of the saw teeth, with a suitable design of the engagement element, rotation in the locking position in the first direction or the second direction can thus be prevented.
    If the flanks of the saw teeth are rising in the second direction, then in the locking position the actuator can be rotated in the second direction, i.e. shortening the length of the spacer can be prevented.
    If the flanks of the saw teeth are designed to rise in the first direction, then in the locking position the actuator can be rotated in the first direction, i.e. an extension of the length of the spacer can be prevented.
    Advantageously, the blocking element can be brought into the locking position by the action of an axial force on the rotary element and brought into the unlocking position by the action of an axial counterforce that counteracts the force.
    Earth's gravity can serve as a force and the counterforce can be generated by a magnetic field between the at least one magnet and the at least one counter magnet. It would of course also be conceivable to generate the force, for example by means of a spring element, and to generate the counterforce by means of the magnetic field, etc. If gravity is not intended as a force, then a non-perpendicular alignment of the spacer element is also possible.
    Advantageously, the rotary element can be moved axially by the action of the force or counterforce in the spacer element in order to bring the blocking element into the locking position or unlocking position. This is particularly advantageous if the rotary element is connected to the actuator via a tongue and groove connection and the threaded sleeve has an opening on the upper side facing the adjusting key, into which the rotary element is inserted. In this embodiment, the rotating element can be moved axially in the threaded sleeve by the action of the force or counterforce.
    Furthermore, the threaded sleeve can have at least one mounting element to which a height-adjustable plate can be attached, so that the plate between the at least
    -45/24
    AT-3982 AT a mounting element and adjusting key is attached. The plate can be attached to the mounting elements, for example by means of screws or bolts or an adhesive. The threaded sleeve is thus held in a stationary position, which is particularly advantageous if the engagement element is attached to the threaded sleeve, since the engagement element is thus also held in a stationary position. The height-adjustable plate can thus cause a constant distance between the adjusting key and the threaded sleeve. If the actuator is axially displaceable in the spacer element to bring the actuator together with the blocking element into the locking position or into the unlocking position and if gravity is used as the force and the magnetic force is used as a counterforce, it must of course be ensured that the actuator together with the blocking element when the Adjusting key can be brought from the locking position into the unlocking position by means of the magnetic force. As soon as the adjustment key is no longer applied, the magnetic force between the magnets and the counter magnets no longer acts, the actuator is displaced axially as a force due to the gravity of the earth, whereby the blocking element falls into the locking position and is then in engagement with the engagement element. In this position, depending on the configuration, it is not possible to rotate the actuator in the first and / or second direction. In this embodiment, special attention must be paid to the position and strength of the magnets and countermangets, as well as the play of the blocking element between the locking position and the unlocking position, in order to enable “actuation” of the blocking element. It is not only necessary to select the thickness of the plate (and the position of the magnets on the adjusting key and the counter magnets on the rotating element) so that a magnetic field is sufficient between the counter magnets of the actuator and the magnets of the adjusting key to transmit the rotary movement , but also be ensured that the magnetic distance between the magnets of the actuator and the adjusting key in the locking position allows the magnetic field to act and consequently bring the blocking element into the unlocking position.
    The actuator is advantageously mounted on a compensating foot. This allows the actuator to tilt and take a vertical position on uneven floors. In addition, the leveling foot can provide sound insulation, i.e. to enable the sound connection of the spacer element, or a plate attached to the mounting elements, if necessary, and the substrate. This decoupling can also be carried out by a decoupling element made of a suitable material, such as felt, rubber, foam, etc., attached to the compensating foot.

    The device described can be used in any area that requires contactlessly adjustable elements. In particular, a height-adjustable floor element for a moisture-proof device, preferably a floor plate of a shower tray, can have at least one device for height adjustment described above, the height of the floor element attached between the adjustment key and driver being adjustable by turning the adjustment key. This makes it possible to adjust the height of the floor element using an adjusting key without visible gaps, cracks, etc. being visible by screws or the like. It is also possible to adjust the inclination of the floor element, for example by using several devices for height adjustment at several points on the floor element, preferably at the corners. Of course, one side of the floor element could also be mounted and devices for height adjustment could be attached on the opposite side of the floor element in order to adjust the inclination of the floor element. Of course, no great pressure should be exerted on the base element during the adjustment, so that the length of the spacer element can be adjusted without contact. In particular, an embodiment of the blocking element by saw teeth running on the rotary element in the radial direction with flanks rising in the second direction can be advantageous when used with a base element. After assembly, the blocking element located in the locking position can in particular be prevented from shortening the assembly element and thus lowering the base element.
    Templates can be provided to make it easier to position the adjusting key on an actuator that is generally not visible from the outside. The template thus serves to position the adjustment key, a plate being provided between the actuator and the adjustment key. This has a recess and positioning means. The template is designed such that when the template is positioned on the plate and the adjustment key in the recess, due to the interaction of the positioning means and the plate, the adjustment key is at the position of the actuator on the opposite side of the plate. The positioning means can be provided, for example, by the edge of the template. The edge of the template can interact with the plate by pushing the edge of the template onto the edge of the plate. Alternatively, a e.g. optical marking on or on the plate, which enables positioning of the template or even the adjustment key itself. The template and / or the adjusting key can advantageously be both removable from the plate and also firmly connected to the plate. The adjusting key can of course also be moved over the base plate until the magnets of the adjusting key build up a magnetic field with the counter magnets of the rotating element and the adjusting key engages, so to speak.

    1 shows an embodiment of a preferred embodiment of the device 10 according to the invention. An adjusting key 1 is provided with four magnets M1, the magnets M1 advantageously being designed as neodymium magnets. The magnets M1 can, for example, be inserted into a recess provided in the setting key 1, glued or also cast into the setting key 1. The adjustment key 1 can have a handle that can be made entirely or partially of plastic, for example. The handle makes it easier to turn the adjusting key 1. To strengthen the magnetic field of the magnets M1, a reinforcement bridge 11 made of ferromagnetic material can be attached along at least two magnets M1. In this embodiment, a reinforcement bridge 11 is provided for a pair of magnets M1, which forms a magnetic yoke.
    Furthermore, a spacer 3 is provided, which consists of a rotating element 2, a threaded sleeve 4, an actuator 6 and optionally a compensating foot 5. The rotating element 2 also has a pair of counter magnets M2. A rotary movement of the adjusting key 1 is transmitted via the magnetic coupling between the magnets M1 of the adjusting key 1 and counter magnets M2 of the rotating element 2, whereby the rotating element 2 represents a driver. For this purpose, the magnets M1 and counter magnets M2 must of course be suitably positioned in the adjusting key 1 and in the rotating element 2.
    The threaded sleeve 4 has on the side facing the adjusting key 1 an opening 40 into which the rotating element 2 can be inserted. Furthermore, the threaded sleeve 4 is provided with an internal thread 42 and mounting elements 41. The actuator 6 has a / 24 7 '
    AT-3982 AT to the external thread 61 matched to the internal thread 42. As a result, the length of the actuator 6 together with the screwed-on threaded sleeve 4 can be adjusted via the thread position, whereby the length d of the spacer element 3 can also be adjusted. In order to change the thread position, the actuator 6 is rotated, which is done by transmitting the rotary movement from the adjusting key 1 to the rotary element 2 and subsequently from the rotary element 2 to the actuator 6. This transmission of the rotary movement from the rotary element 2 to the actuator is advantageously carried out via a positive connection, here via a groove 22 on the rotary element 2 and a suitable spring 62 inserted into the groove 22 on the actuator 6. Of course, the groove 22 could also be on the actuator 6 and the spring 62 on the rotating element 2 or another type of positive connection, such as a profiled shaft / hub or the like can be provided. The positive connection is of course intended to enable a relative movement between the actuator 6 and the rotary element 2.
    By turning the actuator 6 with the rotating element 2 in a first direction A, the length d of the spacer element 3 is increased in the direction of the axial axis of rotation. Analogously, the length of the spacer element 3 is reduced in the direction of the axial axis of rotation by rotating the actuator 6 with the rotary element 2 in a second direction B. The axis of rotation is shown in dash-dotted lines in the figures
    According to the invention, a blocking element 23 is provided in the spacer element 3, which can be brought from a locking position V into an unlocking position E, wherein in the locking position V rotation of the actuator 6 in the second direction B and / or in the first direction A is prevented and in the Unlocking position E a rotation of the actuator 6 in the second direction B and / or the first direction A is made possible.
    In the illustrated embodiment, the blocking element 23 is formed by axial recesses or elevations running on the rotary element 2 in the radial direction (here saw teeth running in the radial direction on the rotary element 2 with flanks 230 rising in the second direction B) in order to achieve the locking position V in the Prevent rotation of the actuator 6 in one direction (here the second direction B). For this purpose, the blocking element 23 is in the locking position V with the engagement element 43 (here two axially projecting ramp elements rising in the first direction A, which is provided here diametrically on the threaded sleeve 4). This prevents the length d of the spacer element 3 from being shortened in the locking position V by locking the second direction B. The engagement element 43 can of course also be designed in other shapes, for example in a rectangular shape or as a trapezoid. The engagement element 43 must of course always be designed in such a way that it can interact with the blocking element 23 in a suitable manner.
    / 24 8 '
    AT-3982 AT
    The blocking element 23 can be brought into the locking position V by the action of an axial force F on the rotating element 2 and can be brought into the unlocking position E by the action of an axial counterforce F 'counteracting the force F. The counterforce F ″ must of course be greater than the force F if the two forces act simultaneously. In the illustrated embodiment, the earth's gravity serves as the force F, the counterforce F 'being generated by the magnetic field between the at least one magnet M1 and the at least one counter magnet M2. If the adjusting key 1 for setting the spacer element 3 is put on, the magnet M1 and the counter magnet M2 act together and thus generate the counterforce F ″ with which the rotating element 2 is lifted and the unlocking position E is brought. The spacing element 3 can thus be adjusted when the adjustment key 1 is attached. After adjustment, the adjustment key 1 is removed, with the result that the counterforce F 'disappears and the acting force F (here the earth's gravity) brings the rotary element 2 into the locking position V. A further adjustment of the spacer 3 is no longer possible. The rotary element 2 can thus be moved axially by the action of the force F or counterforce F 'in order to bring the blocking element 23 into the locking position V or unlocking position E. As a result of the interaction of the spacer 3 and the adjusting key 1, an automatic unlocking or locking can also be achieved when using the spacer 3, which is particularly advantageous for the function of the spacer 3.
    The compensating foot 5 attached to the side of the actuator 6 facing away from the adjusting key 1 serves to support the spacer element 3 in order to enable a vertical position of the spacer element 6 on a non-horizontal floor, the compensating foot 5 being optional. In order to enable a decoupling of the sound connection from the spacer element 3, or a plate 9 attached to the mounting elements 41 to the underlying surface, the compensating foot 5 can also be coated with a decoupling element 51 made of felt, rubber, foam, etc., or also entirely be made of such a material.
    2 a and b show a cross section or an oblique view of the device 10 with the blocking element 23 in the locking position V. The spacing element 3 has a variable length d in the direction of the dash-dotted axis of rotation. The adjusting key 1 (not shown) is not placed on the spacing element 3 or at least so far away that a magnet spacing I between the magnets M1 and the counter-magnet M2 is so large that there is not a sufficient magnetic field around the blocking element 23, which here on the rotating element 2 is appropriate to bring into the unlocking position E. The counter magnets M2 of the rotating element 2 are not visible in this illustration, but the reinforcing bridges 11 are visible. The blocking element 23 (here in the form of a sawtooth)

    AT-3982 AT nen with flanks 230 rising in the second direction B) is in the predominant locking position V with the engagement element 43 (in FIGS. 2a, b, as well as in FIGS. 3a, b, only one in the first direction A for the sake of clarity) rising ramp shown) engages and prevents rotation of the actuator 2 here in the first direction A. This is the case because gravity acts as a force F on the actuator 2. A rotary movement of the rotating element 2 in the first direction A could otherwise also be carried out without attaching the adjusting key 1 via the positive connection, e.g. in the form of a groove 22 and a spring 62 (the latter not visible here), are transferred to the actuator 6, whereby the length d of the spacer 3 is changed. A rotation of the actuator 2 in the second direction B would be more possible in this embodiment, the actuator 2 and threaded sleeve 4 acting like a ratchet. In order to block rotation in the second direction B and instead enable rotation in the first direction, the orientation of the sawtooth-like blocking elements 23 and the ramp-shaped engagement element 43 would have to be reversed. In order to prevent rotation in both directions A and B, blocking elements 23 would be conceivable, for example, as rectangular radial recesses, possibly with trapezoidally beveled sides, on the actuator 2 with a suitable engagement element 43.
    3a and b show a cross section or an oblique view of the device 10 in the unlocking position E. The adjusting key 1 is positioned here at a distance a from the rotary element 2, the generally constant distance a being indicated by a plate 9 (only indicated here) is caused. The counter magnets M2 of the rotating element 2 are not visible in this illustration, but the reinforcing bridges 21 are visible. By acting the magnetic force as counter force F 'between the magnets M1 and the counter magnets M2, the actuator 2 is pulled in the direction of the setting key 1. The magnets M1 of the adjusting key 1 are positioned in this unlocking position E at a magnetic distance I from the counter magnets M2 of the rotating element 2. This magnetic distance I results from the structural nature of the adjusting key 1 and the rotating element 2, i.e. the positioning of the magnets M1 and counter magnets M2, as well as the distance a of the adjusting key 1 from the rotating element 2, or spacing element 3. Of course, the magnets M1 of the adjusting key 1, or the counter magnets M2 of the rotating element 2, are advantageously to be attached in such a way that the magnetic distance I to be kept low, ideally directly at the edge of the adjusting key or the rotating element 2, with which the magnetic distance I corresponds approximately to the distance a. When using neodyn magnets, with four magnets M1 in the setting key 1 and four counter magnets M2 on the rotating element 2, a maximum magnetic distance I of 5 mm must be provided in order to enable the rotary movement to be transmitted. The distance can also be increased in the case of a stronger or a larger number of magnets M1, M2. Since the blocking element 23 is not in engagement with the engaging element 43, a rotary movement of the adjusting key 1 can therefore be caused by the magnets M1 of the adjusting key
    AT-3982 AT seis 1 can be transferred to the magnets M2 of the rotating element 2. The resulting rotary movement of the rotating element 2 is in turn via the positive connection, e.g. in the form of a groove 22 and a spring 62 (not visible here), transferred to the actuator 6. Since the actuator 6 has an external thread 61 onto which a threaded sleeve 4 with an internal thread 41 is screwed, the rotation of the actuator 6 changes the extension of the actuator 6 and the threaded sleeve 4, which also changes the length d of the spacer 3 yes and others the actuator 6 and the threaded sleeve 4 includes changes. However, the distance a and the magnetic distance I remain constant, i.e. the effect of the magnets M1 and counter magnets M2 is the same over the entire adjustment range.
    4 shows an assembled spacer element 3, the threaded sleeve 4 being connected to a plate 9 via assembly elements 41. The plate 9 is thus located between the spacer 3 and the adjusting key 1. The thickness of the plate 9 thus determines the distance a between the adjusting key 1 and the spacing element 3, which subsequently determines the magnet spacing I (in addition to the positioning of the magnets M1 in the adjusting key 1 and the counter magnet in the spacer 3). The rotary movement transmitted to the spacer 3 by the adjusting key 1 changes the length d of the spacer as described above, whereby the height of the plate 9 can be adjusted. 3 shows a template 12 for positioning the setting key 1 at the position of the actuator 6 on the opposite side of the plate 9. The template 12 has a recess for the positioning of the adjusting key 1, the template edge serves as a positioning means. When the template 12 is positioned on the plate 9 and the adjusting key 1 in the recess, the adjusting key 1 is brought to the desired position by the interaction of the positioning means (ie the edge of the template) and the plate 9. The interaction of the positioning means and the plate 9 takes place in this case by a flush application of the positioning means (the edge of the template) to the edge of the plate 9.
    5 shows a shower tray with a floor element 13, which consists of a (floor) plate 9 and four devices 10 according to the invention at the corners of the plate 9. By means of four spacer elements 3 and adjusting key 1, the latter being brought into the correct position by means of templates 21, the height of the plate 9 can be adjusted at four points, whereby any inclination of the plate 9 is set within the adjustment range of the length d of the device 10 can be removed without removing the plate 9. Any gaps, crevices, etc. are avoided by visible screws, which is good for hygiene, especially in wet areas, since no dirt and bacteria can collect in these gaps, crevices, etc. In addition, a tightness of the floor element is guaranteed.

    In order to additionally prevent the spacer element 3 from moving independently or unintentionally, the thread consisting of the internal thread 42 and the external thread 61 can preferably be designed to be self-locking. This means that the friction within the thread is so high that it is not caused by external load on the spacer element 3 or a base element 13, e.g. due to a user climbing on it rotates and thus adjusts the length d of the device 10. In this way, the base element 13 would possibly change the preset and desired position, that is, lower it. This friction in the thread can e.g. by a small thread pitch or by large flank surfaces of the thread, e.g. can be achieved with a trapezoidal thread, as exemplified in the figures. An additional friction can also be generated between the threaded sleeve 4 and the actuator 6, or e.g. a liquid screw lock slide can be applied in the thread. This screw locking slide must be applied by the fitter prior to assembly and, after a defined time, glues the internal thread 41 to the external thread 61.
    The compensating foot 5 can have a positive connection, e.g. 1, with the actuator 6 - of course the actuator 6 must have a suitable recess - so that the compensating foot 5 rotates with the actuator 6. This can prevent an undesirable adjustment of the length d of the device 10, since the actuator 6 can only be rotated when the compensating foot 5 also rotates, which can be ruled out when the spacer element 3 is loaded due to the friction between the compensating foot 5 and the ground.
