Description

[0001] The present invention relates to a rosette for pipe clamps with hanger bolts, comprising or consisting of a rosette body having a through-opening, wherein the through-opening at least partially has an internal thread that can be screwed onto the thread of the hanger bolt. The present invention also relates to a set comprising a pipe clamp with hanger bolts and a rosette according to the invention, as well as the use of a rosette according to the invention for fastening to the hanger bolt of a pipe clamp.

[0002] Pipe clamps with hanger bolts are widely used fastening elements, particularly in plumbing, heating, and air conditioning systems, to secure pipes to walls or ceilings. A pipe clamp usually consists of a metal bracket that encloses the pipe and can be secured with a screw connection. Fastening to the wall is typically done using hanger bolts, which are screwed into the masonry and usually secured with dowels.

[0003] Despite their proven functionality, pipe clamps with hanger bolts pose several aesthetic and technical problems. After installation, a visible drill hole often remains around the hanger bolt. This is often perceived as visually disturbing, especially in visible areas such as bathrooms or living rooms. This is especially the case when parts of the plaster break away when drilling the holes required for fastening, which cannot always be avoided even with careful work.

[0004] Particularly in older buildings, there is often the problem that the masonry is no longer stable enough or is made of porous materials or has different structures in different places. This can lead to anchors not holding well, which causes the hanger bolt to wobble or come loose. Even with professional installation, the hanger bolt may not be fully seated in the wall, especially in hollow spaces or brittle plaster. This causes the pipe clamp to lose load-bearing capacity and stability, which is particularly problematic for heavier pipes. In humid environments, e.g. in bathrooms, or when exposed to corrosive substances, e.g. in industrial plants, a loose hanger bolt can corrode more quickly. Especially with pipe clamps installed outdoors, water or dirt can penetrate through the exposed drill holes, which can cause long-term damage to the masonry.

[0005] The object of the present invention was to find a way to completely or at least partially eliminate the disadvantages of pipe clamps with hanger bolts described above.

[0006] This object was achieved by a rosette for pipe clamps with hanger bolts comprising or consisting of a rosette body which has a through-opening, wherein the through-opening has at least partially an internal thread which can be screwed onto the thread of the hanger bolt, or the through-opening has a holding means which holds positively or non-positively on the thread of the hanger bolt.

[0007] Pipe clamps with hanger bolts are typically used to securely attach pipes to walls, ceilings, or other solid surfaces. Installation involves several steps, which may vary slightly depending on the wall material and pipe type. First, a hole is drilled into the wall at the desired location. After cleaning the drill hole, a dowel is inserted into the hole. A hanger bolt, which has a dowel thread (wood thread) on one end and a metric thread (machine thread) on the other, is then screwed into the dowel using its dowel thread. The pipe clamp is then attached to the metric thread, which secures the pipe.

[0008] Before attaching the pipe clamp, a rosette according to the invention can be screwed onto the metric thread of the hanger bolt and turned downward until the rosette body is flush with the wall. Our own investigations have shown that using the rosettes according to the invention can generally completely cover the drilled holes. Furthermore, at least part of the hanger bolt is enclosed by the rosette and thus shielded from environmental influences, which can reduce or prevent corrosion of the bolt.

[0009] By choosing the appropriate hanger bolt length, it's even possible to enclose the entire hanger bolt within the rosette. This not only prevents corrosion of the hanger bolt and reduces the penetration of water or other substances into the wall, but has also been shown to create an aesthetically pleasing finish.

[0010] Surprisingly, it has also been shown that by tightening rosettes according to the invention, the stability of the hanger bolt screwed into the masonry can be improved, since shearing forces can be diverted into the masonry via the rosette resting on the masonry.

[0011] In addition to fastening the rosette to the hanger bolt by means of an internal thread that can be screwed onto the thread of the hanger bolt, it is preferred according to the invention if the through-opening has a holding means that holds positively or non-positively on the thread of the hanger bolt. In this case, the through-opening is designed such that it enables the rosette to be held on the thread of the hanger bolt. A rosette according to the invention is preferred, wherein the holding means is an elastic constriction. The elastic constriction can, for example, be a rubber lip or an area made of an elastomer and reduce the diameter of the constriction to such an extent that it corresponds to the diameter of the hanger bolt or is slightly larger or slightly smaller (preferably smaller) than this. This makes it possible to slide the rosette onto the hanger bolt without having to screw it onto the thread.This can save a significant amount of time. It can also improve the seal between the rosette and the hanger bolt.

[0012] According to the invention, it is also possible for the holding means to comprise a mechanical clamping or locking element that clamps the rosette onto the thread of the hanger bolt. For example, the holding means can have a spring-loaded push button or a similar actuating mechanism with which the rosette can be selectively released or fixed. By pressing the push button, the clamping effect can be released and the rosette can be moved or removed from the hanger bolt; by releasing it, it is securely held on the thread again. Such a holding means enables simple and tool-free assembly and disassembly of the rosette.

[0013] A rosette according to the invention is preferred which has a rubber seal on the side facing the masonry. A rubber seal further improves the seal between the masonry and the rosette and can compensate for unevenness in the masonry. The rubber seal can be a flat seal with a through-hole for the hanger bolts, which is either loosely inserted or connected to the rosette (for example by gluing). A corresponding rosette according to the invention is preferred, wherein the rubber seal has a thickness in the range of 1 to 50 mm, more preferably in the range of 2 to 40 mm, particularly preferably in the range of 3 to 30 mm.

[0014] A rosette according to the invention is preferred, wherein the rosette body is substantially a cylinder, substantially a cylinder with a conical collar or substantially a truncated cone and the through opening runs along the cylinder axis.

[0015] The chosen shape ensures even force distribution and a stable contact surface against the wall. A conical collar or truncated cone, in particular, facilitates installation and allows for good adaptation to different wall surfaces.

[0016] A rosette according to the invention is preferred, wherein the ratio of the height (h) of the cylinder or truncated cone to the mean diameter (d) of the cylinder or truncated cone is greater than 1 (h / d > 1), preferably greater than 1.5, more preferably greater than 2, more preferably greater than 3.

[0017] A larger height-to-diameter ratio provides better coverage of the hanger bolt and the drilled hole. Additionally, a taller rosette provides greater stability by further reducing the risk of tilting or wobbling of the hanger bolt.

[0018] A rosette according to the invention is preferred, wherein the ratio of the maximum diameter of the cylinder or truncated cone (d_max) to the height (h) of the cylinder or truncated cone is in the range from 0.8:1 to 1.2:1, preferably in the range from 0.9:1 to 1.1:1, more preferably in the range from 0.95:1 to 1.05:1, more preferably about 1:1.

[0019] A nearly balanced diameter-to-height ratio ensures a harmonious and compact design that is neither too protruding nor too narrow. This achieves an optimal combination of stability, appearance, and functionality.

[0020] A rosette according to the invention is preferred, wherein the maximum diameter of the cylinder or truncated cone (d_max) is in the range from 10 mm to 60 mm, preferably in the range from 15 mm to 50 mm, more preferably in the range from 20 mm to 40 mm, more preferably about 30 mm.

[0021] A rosette according to the invention is preferred, wherein the height (h) of the cylinder or truncated cone is in the range from 5 mm to 50 mm, preferably in the range from 7 mm to 30 mm, more preferably in the range from 10 mm to 20 mm, more preferably about 15 mm.

[0022] A rosette according to the invention is preferred, wherein the cylinder or truncated cone is rotationally symmetrical along its cylindrical axis. This rotational symmetry ensures that any rotation around this axis by any angle results in a shape that is congruent with the initial position.

[0023] The rotational symmetry allows the rosette to be rotated freely, simplifying installation. Furthermore, the symmetrical shape ensures even force distribution, improving stability.

[0024] Plastic is lightweight, corrosion-resistant, and inexpensive to produce. It also allows for easy processing and can be modified to meet specific requirements (e.g., conductive, impact-resistant).

[0025] A rosette according to the invention is preferred, wherein the rosette body consists entirely or at least predominantly of plastic.

[0026] A rosette according to the invention is preferred, wherein the plastic is selected from the group consisting of polyvinyl chloride (PVC), polypropylene (PP), acrylonitrile butadiene styrene (ABS), polyamide (PA), polyoxymethylene (POM), polycarbonate (PC), polyetheretherketone (PEEK), polytetrafluoroethylene (PTFE), high density polyethylene (HDPE), polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), styrene acrylonitrile (SAN), polybutylene terephthalate (PBT), polyphenylene sulfide (PPS) and acrylonitrile styrene acrylate (ASA).

[0027] By selecting the right material, the rosette can be adapted to different requirements, such as high temperature resistance (PEEK, PTFE, ASA), impact resistance (PC, ABS, ASA) or chemical resistance (PP, PVC, POM, ASA).

[0028] A rosette according to the invention is preferred, wherein the plastic is mixed with conductive fillers such as carbon fibers, graphite, carbon black, metallic particles or conductive polymers.

[0029] The rosette can therefore dissipate static charges or conduct electrical currents, which is advantageous in ESD-sensitive areas or potentially explosive environments.

[0030] A rosette according to the invention is preferred, wherein the surface of the rosette is provided with a conductive coating in order to ensure targeted electrical dissipation.

[0031] A conductive coating offers a cost-effective alternative to continuous conductive material and can be applied in a targeted manner to prevent electrostatic discharge or to provide electrical shielding.

[0032] A rosette according to the invention is preferred, wherein the rosette body consists of a material which is either statically dissipative or electrically conductive, wherein the specific electrical resistance of the material is in a range of 10 4 Ω·cm to 10 -2 Ω·cm.

[0033] Due to this controlled electrical resistance, the rosette can serve as ESD protection or as part of an electrical contact system, depending on the application.

[0034] A rosette according to the invention is preferred, wherein the rosette body is colored or painted yellow, brown, red, green, blue, orange, gray, black or violet.

[0035] The coloring of the rosette can serve functional or safety-related purposes, for example for better visual integration into the environment.

[0036] A rosette according to the invention is preferred, wherein the internal thread is a fine thread, preferably a metric thread in the nominal size 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm or 12 mm.

[0037] According to the invention, the internal thread is preferably a deformable thread which enables the screwing on of dirty, brittle or damaged threads.

[0038] A fine thread allows for more precise adjustment of the rosette and ensures a firm and secure connection to the hanger bolt.

[0039] A rosette according to the invention is preferred, wherein the internal thread is incorporated into the rosette body, in particular a) by thread cutting or thread forming into the plastic body or b) by inserting a metal nut with an internal thread, which is firmly anchored in the rosette body.

[0040] A threaded structure cut directly into the plastic is cost-effective and lightweight, while an incorporated metal nut offers greater mechanical strength and prevents overtightening of the thread.

[0041] A rosette according to the invention is preferred, wherein the diameter of the rosette decreases from the wall to the pipe clamp, in particular in a conical shape, wherein the larger diameter faces the wall.

[0042] A conical shape allows for better adaptation to the wall and ensures easier installation of the rosette. It also creates a harmonious visual integration into the overall appearance of the installation.

[0043] A rosette according to the invention is preferred, wherein the internal thread is arranged in the upper part of the rosette so that it is located in the area directed towards the pipe clamp.

[0044] The placement of the thread in the upper area of the rosette ensures that the load transfer is optimally distributed and a stable connection between the pipe clamp and the hanger bolt is guaranteed.

[0045] A rosette according to the invention is preferably characterized by a machine-readable code, in particular a QR code, applied to the outer surface of the rosette body. The code can be applied, for example, by gluing or printing on the rosette. Alternatively, the machine-readable code can be embossed directly into the rosette or—if the rosette is produced using a 3D printing process—printed on it.

[0046] Embossing or printing the code offers the advantage of high weather resistance and ensures readability throughout the entire lifespan of the rosette. In contrast, adhesive or printed codes can become illegible over time due to environmental influences.

[0047] The machine-readable code is preferably colored black to create a clear contrast with the light-colored rosette. Ideally, it is positioned on a specially designed, flat surface of the rosette body. This design ensures that the code is reliably machine-readable regardless of the installation position.

[0048] The machine-readable code either directly encodes user- and object-specific information about the associated piping system or contains a reference (e.g., a URL link) to a digital information platform that can be accessed by scanning the code. Examples of encoded or digitally stored information include: • Information on the type of pipe used and the medium (e.g. drinking water, heating water, condensate), and / or • location-related information, such as the location of barriers, and / or • technical details of the installed piping system, and / or • a digital logbook with information on maintenance and repair measures, and / or • Owner, operator or inspection data.

[0049] The use of an inventive rosette with a machine-readable code enables unique identification of each line unit. The digital linking of relevant data creates significant advantages in terms of maintenance, documentation, and operational and planning reliability.

[0050] In a preferred embodiment, the rosette is available both with and without a machine-readable code. If a version with a code is selected, this code preferably refers to a digital information platform whose maintenance, care, and availability are ensured separately. For this variant, it is advantageous if the customer chooses a subscription model or a flat-rate fee for the provision and maintenance of the digital content.

[0051] Furthermore, it is preferred that the provider offer a separate commissioning or configuration service for the initial activation of the machine-readable code and the setup of the digital content. This may include, in particular, the assignment of object-specific information, the structuring of the data content, and the connection to a digital management system.

[0052] This optional service extension provides users with not only the mechanical functionality of the rosette, but also digital documentation and management of piping information. This significantly expands the rosette's application possibilities, particularly in technical building management, maintenance coordination, and system history tracking.

[0053] A further aspect of the present invention relates to a set consisting of or comprising a) a rosette according to one of claims 1 to 15 and b) a hanger bolt and / or a pipe clamp. A set is preferred, wherein the set additionally contains a dowel.

[0054] The set, consisting of a rosette, hanger bolt and / or pipe clamp, and, if necessary, a dowel, offers numerous practical, aesthetic, technical, and economic advantages by enabling a faster, more stable, and more aesthetically pleasing fastening solution. It minimizes mismatches, increases the service life of the fastening, and simplifies installation, especially in older buildings or challenging environments.
