Description

Technical Field

[0001] This invention relates to a fastening device for bathroom components to be hung, and more particularly to a fastening device for toilet seats to be hung on a wall. Background Technology

[0002] To install toilets, fastening systems have traditionally had to be operated under difficult and ergonomic conditions. This, for example, requires the installer to at least partially climb under the toilet seat. Furthermore, systems typically used for installation are inherently fragile, often pre-secured or initially tightened, and may break during final installation, rendering the installation kit unusable as intended. An exemplary system is described here in which screw elements are not screwed into the ceramic body or toilet seat, but rather clamped relative to the bathroom mounting element like a flange (interlocking screw connection). This system contains significantly more components than a conventional interlocking screw connection, allowing the clamping force required for such applications to be applied at a 90° angle rather than axially. Additionally, this system is used to pre-secure the toilet to a support pin on the bathroom mounting element. Summary of the Invention

[0003] Therefore, the object of the present invention is to at least partially solve the problems described with reference to the prior art. In particular, a fixing device for a bathroom component to be suspended, especially a toilet seat, is proposed, which enables convenient, quick and / or secure fastening of the bathroom component to a retaining bolt that works in conjunction with the wall.

[0004] These objectives are achieved using the fastening device and method for mounting bathroom fixtures to be suspended on a wall, as described in the independent claims. It should be noted that the features individually listed in the dependent claims can be combined with each other in any technically meaningful manner and define other embodiments of the invention. Furthermore, the features described in the patent claims are described and explained in more detail in the specification, wherein other preferred embodiments of the invention are presented.

[0005] A fastening device for bathroom fixtures to be suspended facilitates these purposes, and the fastening device comprises at least two components:

[0006] - At least one adapter pin, configured to receive or include a retaining plug for a bathroom component at a first end, and also having a widened retaining protrusion at a second end; and

[0007] - At least one rotatable protrusion retaining device, the protrusion retaining device being configured to receive and lock the retaining protrusion of the adapter pin.

[0008] The fastening device proposed herein is in particular a kit consisting of two separate components: at least one adapter pin and at least one protrusion retaining device. Typically, the fastening device for exactly one retaining pin also comprises only exactly one separate adapter pin and a separate protrusion retaining device. Here, the adapter pin and / or protrusion retaining device are implemented such that they are able to withstand installation forces and / or forces generated during the use of the bathroom component.

[0009] The adapter pin is preferably an elongated member having a circumferential surface and two opposing ends. Preferably, the end referred to herein as the first end is designed to receive or include a retaining plug for the bathroom component. For the case where the adapter pin includes a retaining plug, a one-piece implementation can be chosen. More preferably, the adapter pin includes a receiving portion for the retaining plug at the first end, particularly extending from the end side of the first end, such that this end section of the adapter pin can at least partially surround or clamp the retaining plug. For example, it is possible to screw the retaining plug onto or tighten it into the adapter pin. Appropriate threads can be provided for this purpose. Preferably, the retaining plug is received in the first end of the adapter pin in such a way that the retaining plug and the adapter pin are arranged aligned with each other along a direction referred to herein as the mounting axis. Therefore, in the installed state, the adapter pin can be considered as an extension for the retaining plug.

[0010] Then, the adapter pin can be designed to taper gradually after the receiving area for retaining the pin, i.e., at a certain distance from the first end, and then widen again towards the second end. Specifically, a widened retaining protrusion / retaining disc is provided at the second end. The retaining protrusion can be implemented in the form of a disc-shaped pin head, which is also widened in the circumferential direction of the adapter pin. However, this is not absolutely necessary. In particular, viewed from the second end of the adapter pin, the widened retaining protrusion forms a side recess. This side recess is specifically designed to cooperate with a rotatable protrusion retaining device.

[0011] Therefore, the protrusion retaining device is configured to receive and lock the retaining protrusion of the adapter pin. In other words, this specifically means that the protrusion retaining device forms a cavity or similar structure into which the retaining protrusion of the adapter pin can be inserted. Preferably, the protrusion retaining device is designed such that the retaining protrusion of the adapter pin can only enter the cavity when the adapter pin and the protrusion retaining device are in a precisely predetermined relative position. The protrusion retaining device is implemented to be rotatable, wherein the axis of rotation of the protrusion retaining device is oriented, in particular, perpendicular to the mounting axis of the adapter pin. Thus, it is particularly possible that the adapter pin can first be partially inserted into and received in the protrusion retaining device in a predetermined position, and then the extension movement of the adapter pin from the protrusion retaining device is prevented by rotational movement. This is preferably prevented by form-locking. The adapter pin is particularly considered to be "locked" when it can no longer be guided out of the protrusion retaining device along the mounting axis (by translational movement only).

[0012] It is particularly preferred that at least one adapter pin and at least one protrusion retaining device are made of metal or a material equivalent in mechanical properties. Therefore, the adapter pin and protrusion retaining device are specifically configured to bear the load that may occur on the bathroom component to be suspended, especially the toilet seat.

[0013] Preferably, at least one adapter pin and at least one protrusion retaining device form a bayonet-type connection mechanism. This specifically means that the adapter pin can be first inserted into the protrusion retaining device in a predetermined position relative to the protrusion retaining device, and then, by rotating the protrusion retaining device, form-locking and / or force-locking is achieved, preventing the adapter pin from moving backward out of the protrusion retaining device. For this purpose, the protrusion retaining device can have an internal profile through which the adapter pin, especially the widened retaining protrusion, is locked. It is also possible that the bayonet-type connection mechanism is designed such that the precise relative positioning of the widened retaining protrusion occupies the interior of the protrusion retaining device. Therefore, the bayonet-type connection mechanism can also be used, in particular, to secure a bathroom component relative to a wall in such a way that, when the protrusion retaining device is twisted, the widened retaining protrusion moves further into the internal region of the protrusion retaining device, and thus the bathroom component is moved closer to the wall via the retaining protrusion. In particular, this bayonet-type connection mechanism is an establishable and repeatedly releaseable mechanical connection between the adapter pin and the protrusion retaining device.

[0014] Furthermore, it is proposed that at least one adapter pin and at least one protrusion retaining device are received in at least one mounting sleeve having a mounting axis in such a way that at least one adapter pin can be inserted along the mounting axis and at least one protrusion retaining device can rotate about a rotation axis perpendicular to the mounting axis.

[0015] The mounting sleeve is preferably configured such that it fully or almost fully receives at least one adapter pin and at least one protrusion retaining device. Specifically, the mounting sleeve extends generally parallel to or coaxial with the adapter pin. The mounting sleeve can be designed to be open at both end regions, for example, via holes. Similarly, the mounting sleeve has a first end through which the adapter pin (if desired, together with a retaining pin) can be inserted. The protrusion retaining device is positioned away from this first end, particularly near the opposing second end. It is possible that the protrusion retaining device can be radially inserted into the mounting sleeve, wherein, if desired, its re-emergence from the mounting sleeve is achieved solely through form-locking with the adapter pin. The protrusion retaining device can, if desired, be radially exposed beyond the circumference of the mounting sleeve, for example, to facilitate the connection of a tool for achieving rotational movement. Therefore, the mounting sleeve can be provided with a radial notch through which the protrusion retaining device can be inserted into an internal region of the mounting sleeve. Mounting sleeves can be constructed as a single piece or in multiple pieces, for example, consisting of 2, 3, 4, or 5 (sleeve-shaped parts that can be screwed together if needed). In the case of multi-piece mounting sleeves, the distance can be adjusted correctly or bridging can be flexible.

[0016] Preferably, at least one mounting sleeve is designed as a two-piece sleeve, wherein the first mounting sleeve portion is at least partially received and lockable into the second mounting sleeve portion. Specifically, the adapter pin (only) contacts the first mounting sleeve portion (directly), and the protrusion retaining device (only) contacts the second mounting sleeve portion (directly). Providing a two-piece mounting sleeve allows the relative positioning of the first and second mounting sleeve portions to be adjustable. For example, this can be used to adjust the relative positioning of the adapter pin and the protrusion retaining device for pre-installation positioning. In particular, these mounting sleeve portions may collectively be constructed with a threaded section through which the relative positioning can be precisely adjusted and locked.

[0017] The mounting sleeve, or rather the mounting sleeve portion, is preferably made entirely of plastic.

[0018] Furthermore, it is proposed that the first and second mounting sleeve portions each have outwardly projecting clamping flanges. The clamping flanges are preferably implemented circumferentially. In particular, the two opposing clamping flanges are used to secure components extending between the clamping flanges or to secure the mounting sleeve there in a precise mating manner. Specifically, the clamping flanges are used in conjunction with the bathroom component to quickly and easily fasten the mounting sleeve into or onto the bathroom component. Preferably, the two clamping flanges are arranged on the end sides of the first and second mounting sleeve portions.

[0019] Furthermore, it is proposed that at least one protrusion retaining device includes at least one locking lug, which can be operatively connected to at least one mounting sleeve, thereby at least impeding the opening movement of the protrusion retaining device. In particular, at least one locking lug is formed of metal, while the mounting sleeve is made of plastic.

[0020] It is possible that the protrusion retainer has multiple rib-like locking lugs on its circumferential surface, which, when the overall assembly is secured, or the toilet seat is firmly fixed to the wall, cooperate with the material near the notch in the mounting sleeve, for example. The locking lugs then serve, if necessary, only in the secured condition, to increase friction relative to the mounting sleeve. Alternatively or additionally, a reverse profile may be provided close to the mounting sleeve, wherein the locking lugs located at the bottom of the protrusion retainer cooperate with this reverse profile. The resulting resistance also prevents the opening of the protrusion retainer, i.e., the rotation of the protrusion retainer. The design of the (multiple) locking lugs preferably prevents unwanted opening movements, for example, during subsequent operation of the bathroom fixture.

[0021] According to another aspect, a bathroom component, particularly a toilet seat, is proposed having at least one through-channel for retaining a plug and at least one additional notch leading to the through-channel, wherein at least one fastening device of the type described herein can be arranged in the through-channel such that at least one protruding retaining device can be rotated via the notch. The bathroom component may be formed of ceramic, mineral casting, metal, plastic, or similar materials.

[0022] In particular, the bathroom component is designed such that the passageway is substantially perpendicular to the wall of the area behind the bathroom component. Preferably, the notch extends from the upper side of the bathroom component (in the installed state) to the passageway. The axis of rotation of the fastening device, especially the protrusion retainer, is now arranged such that the protrusion retainer can be rotated through the notch using conventional tools such as screwdrivers, Allen wrenches, etc. Therefore, the axis of the notch and the axis of rotation of the protrusion retainer are substantially parallel and coaxial. With suitable installation and / or tools (e.g., ball-headed Allen wrenches), a certain degree of deviation in the axis position is also permissible; for example, deviations of up to approximately 45° in the axis position can be compensated for if necessary, regardless of whether the system is skewed or whether this angle is caused by an offset.

[0023] More preferably, the notch is provided for securing functional components. Therefore, for example, the notch may be provided for securing additional bathroom fixtures, fittings, closures, covers, etc. In particular, this method avoids the need for additional notches solely for operating fastening devices.

[0024] On another front, a fastening device of the type described herein is proposed for the permanent and precisely positioned mounting of ceramic sanitary ware components to a wall. Preferred ceramic sanitary ware components include toilet seats, bidets, etc. In particular, this application allows for installation from only one direction, i.e., especially from above or below, thus providing the installer with an ergonomically convenient working position.

[0025] According to another aspect, a method for mounting suspended bathroom components to a wall using fastening devices, particularly those already described herein, is explained. The mounting method includes at least the following steps:

[0026] a) Tension (at least) two-piece mounting sleeves onto the shoulder of the bathroom component near the through-channel of the bathroom component, which is used to secure the retaining bolt to the wall.

[0027] b) When the adapter pin and retaining bolt exist as separate components, connect the adapter pin to the retaining bolt.

[0028] c) Insert the adapter pin into the mounting sleeve.

[0029] d) The widened retaining protrusion of the adapter pin is locked by a retaining device arranged in the mounting sleeve with a rotatable protrusion.

[0030] The above description of the fixing device can also be used to characterize the installation method described here. Refer there for the statements made therein, and they may be quoted in full.

[0031] The steps listed here will be performed in roughly the predetermined order a) to d), wherein these steps may overlap at least temporarily if necessary.

[0032] Bathroom fixtures suspended in this manner possess at least some of the aforementioned advantages and are therefore particularly preferred.

[0033] The tensioning achieved in step a) is particularly accomplished by adjusting the relative positioning of the two-piece mounting sleeves, for example, in conjunction with the aforementioned clamping flange. It is evident that the retaining bolt need not be directly or indirectly fixed to the wall; it is also possible that the retaining bolt is part of the mounting frame or mounting wall.

[0034] Connecting the adapter pin to the retaining bolt according to step b) specifically includes screwing the retaining bolt into the adapter pin. If the adapter pin and retaining bolt are implemented as a single piece, step b) can be omitted.

[0035] In step c), the adapter pin is preferably inserted into the mounting sleeve until its retaining protrusion is received inside the protrusion retaining device, which is also disposed in the mounting sleeve.

[0036] The widened retaining protrusion of the lock according to step d) is achieved, in particular, by twisting the protrusion retaining device about a rotation axis perpendicular to the mounting axis. The lock is preferably releasable.

[0037] In summary, the solution described here cleverly utilizes existing holes for installing toilet seats. Specifically, it allows the toilet seat to be supported against the wall from above, eliminating the need to crawl under the toilet.

[0038] First, screw the adapter pin onto the retaining pin. Then, or simultaneously, insert the mounting sleeve into the toilet's mounting hole or through-hole. The protrusion retainer can be inserted into a correspondingly provided lateral hole or notch in the mounting sleeve and axially oriented with the receiving portion of the widened retaining protrusion for the adapter pin. By screwing the adapter pin onto the retaining pin, the adapter pin is positioned to the correct length. The ceramic component, especially the toilet seat, can then be pushed onto the adapter pin, which is inserted into the mounting sleeve located there, along with the protrusion retainer. By turning the protrusion retainer with, for example, a commercially available screwdriver, the protrusion retainer applies the necessary clamping force to the adapter pin. During the clamping process, for example, a grooved locking lug on the circumference or outer side of the protrusion retainer can be embedded in the surface of the mounting sleeve, thereby preventing the protrusion retainer from loosening. Attached Figure Description

[0039] The solutions and their technical applications presented herein are explained in more detail below with reference to the accompanying drawings. It should be noted that the invention should not be limited to the embodiments shown. In particular, unless otherwise expressly stated, certain aspects of the subject matter explained in or in conjunction with the drawings can be extracted and combined with other parts and / or knowledge derived from other drawings and / or this specification.

[0040] Specifically, exemplarily and schematically:

[0041] Figure 1 : Shows a perspective view of the fastening device;

[0042] Figure 2 : Shows the fastening device installed in the suspended bathroom component;

[0043] Figure 3 This illustrates the integration of fastening devices into bathroom components.

[0044] Figure 4 : Showing a cross-sectional view through the fastening device; and

[0045] Figure 5 Example of an adapter pin is shown, which is implemented with a retainer in a one-piece configuration. Detailed Implementation

[0046] Figure 1 A perspective view is shown of a fixing device 1 for a bathroom component 2 to be suspended, and in particular, an adapter pin 3 is shown, which (in the still open position) is partially received by a rotatable protrusion retaining device 8.

[0047] The adapter pin 3 is configured to receive a retaining bolt 5 for the bathroom component at its first end 4. Specifically, the adapter pin 3 is widened in the region of the first end 4 and, for example, has an internally located threaded section for receiving the retaining bolt 5. Conversely, a widened retaining protrusion 7 is provided at the second end 6. Since the adapter pin 3 and the retaining bolt 5 are used together to mount the bathroom component 2 to the wall, they are implemented coaxially with the mounting axis 10. Therefore, securing or fastening is achieved along a fastening movement 26 parallel to the mounting axis 10.

[0048] The second end 6, particularly the widened retaining protrusion 7 utilizing the adapter pin 3, is received by a rotatable protrusion retaining device 8. The protrusion retaining device 8 is rotatable about a rotation axis 11 oriented perpendicular to the mounting axis 10. One direction of rotation results in a locking movement 21, and the opposite direction of rotation causes an opening movement 22 of the protrusion retaining device 8. In one section or at the midpoint relative to the rotation axis 11, the protrusion retaining device 8 is provided with a tool interface, for example, for receiving an Allen wrench.

[0049] The protrusion retaining device 8 also includes a recess 23 through which the second end 6 of the adapter pin 3, together with the retaining protrusion 7, can be laterally inserted into the protrusion retaining device 8. A gap 24 is constructed adjacent to the recess 23 such that, during the locking movement 21, the gap includes the widened retaining protrusion 7 and thus engages. The gap 24 preferably extends (only) partially in the circumferential direction of the protrusion retaining device 8 and is then limited by a stop. An internal contour 25 may also be provided to implement a tightening movement 26 simultaneously with the locking movement 21 or the opening movement 22.

[0050] In addition, the protrusion retaining device 8 has grooved locking lugs 16 designed on its outer surface. When the fastening device is in the clamped state, these locking lugs can be used to cooperate with adjacent components, especially mounting sleeves.

[0051] Figure 2 A fastening device 1 built into the bathroom component 2 is shown. For this purpose, the bathroom component 2 has a shoulder 20, in which a through channel 17 is provided. A retaining bolt 5 to be fastened to the wall 28 extends at least partially through the through channel 17, and the bathroom component 2 is tensioned relative to the wall 28 by means of the retaining bolt 5.

[0052] The adapter pin 3 is screwed onto the retaining bolt 5 by means of thread 27, thereby aligning them with each other along the mounting axis 10. Opposite to the thread 27 at the other end, the adapter pin 3 is provided with a widened retaining protrusion 7.

[0053] A two-piece mounting sleeve 9 is provided in the through channel 17 of the bathroom component 2. The mounting sleeve 9 has a first mounting sleeve portion 12 and a second mounting sleeve portion 13. The first mounting sleeve portion 12 has an external thread 27 at its (left) end, which is used to fix the first mounting sleeve portion into the second mounting sleeve portion 13. A first clamping flange 14 is provided at the opposite (right) end of the first mounting sleeve portion 12. The second mounting sleeve portion 13 also has a second clamping flange 15 in the area of ​​the thread 27. The relative positioning of the first clamping flange 14 and the second clamping flange 15 can be adjusted via the thread 27 between the first mounting sleeve portion 12 and the second mounting sleeve portion 13, thereby securing the two clamping flanges 14, 15 to the shoulder 20 of the bathroom component 2. Therefore, a rough pre-installation of the mounting sleeve 9 in the bathroom component 2 can be achieved.

[0054] The protrusion retaining device 8 is inserted into a lateral or radial notch 29 in the second mounting sleeve portion 13. Preferably, this arrangement allows the axis of rotation 11 of the protrusion retaining device 8 to extend through an additional notch 18 in the bathroom component 2. A locking lug 16, which provides locking or centering, may be provided on the underside of the protrusion retaining device 8. When the bathroom component 2, with its integrated mounting sleeve 9 and protrusion retaining device 8, is fitted over the adapter pin 3 along with the retaining bolt 5, the widened retaining protrusion 7 engages with the protrusion retaining device 8. By rotating the protrusion retaining device 8, the protrusion retaining device 8 surrounds the retaining protrusion 7, thereby locking the retaining protrusion and applying tension. In this way, the bathroom component 2 can move towards the wall 28 and can be tensioned relative to the wall.

[0055] Figure 3 A cross-section through a bathroom component 2 in the form of a toilet seat is shown, where the relative position of the fastening device 1 and the bathroom component 2 should be clarified again. A through channel 17 for receiving a retaining plug or mounting sleeve 9 is provided at the rear and along the mounting axis 10. The mounting sleeve 9, possibly implemented in a two-piece configuration, can be pre-fixed to a shoulder 20 of the bathroom component 2, which in particular forms the through channel 17. The protrusion retaining device 8 is then oriented along its axis of rotation 11, preferably such that the protrusion retaining device is accessible or operable through an additional notch 18. This notch 18 can, for example, be provided for securing another functional component 19, such as the toilet seat in this case.

[0056] If already used Figure 2 As shown, a safety device can be provided in the mounting sleeve, especially in the second mounting sleeve portion 13, which prevents accidental opening movement of the protrusion retaining device 8. Figure 4 The mounting sleeve is shown in partial cross-section here, where a groove (in the form of a reverse profile) is arranged internally (i.e., not visible from the outside of the mounting sleeve) to cooperate with the locking lug 16. The groove has a structured profile 25, which ensures that it always provides locking positioning for the locking lug 16 and thus prevents movement toward the open position.

[0057] In addition to the functions mentioned above, it also has another advantage: when the tool receiving part is installed with the tool receiving part pointing downwards, the protrusion retaining device 8 prevents it from falling off by two locking caps formed in the mounting sleeve 9.

[0058] Figure 5 The case where the adapter pin 3 includes the retaining bolt 5 is explained, thus allowing for a one-piece implementation. In other words, the retaining bolt 5 is directly molded onto the first end 4 of the adapter pin 3 from the same material. Other aspects are explained above.
