Description

[0001] The embodiments described herein relate to pipe clamping devices, particularly exhaust pipe clamping devices for vehicles such as automobiles or motorcycles, pipe clamping assemblies, and methods for providing positional stability during the clamping of pipe clamping devices and pipe clamping assemblies.

[0002] Pipe clamping devices, especially exhaust pipe clamping devices, can be used in various situations where pipes need to be connected and / or secured, such as in vehicle or automotive applications, marine applications, industrial applications, and / or HVAC (heating, ventilation, and air conditioning) applications.

[0003] For example, exhaust pipe clamps can be used in automotive exhaust systems to connect and secure various components of the system, such as mufflers, catalytic converters, and tailpipes. In these applications, exhaust pipe clamps may need to withstand high temperatures and be exposed to road salt, moisture, and other environmental factors. Additionally, exhaust pipe clamps may need to be able to handle drive-related vibrations and stresses, as well as the thermal expansion and contraction of exhaust system components.

[0004] Exhaust pipe clamping devices can also be used in industrial applications, such as power plants. This can include securing exhaust chimneys to engines or turbines and connecting pipes and other components within the exhaust system itself. In these applications, exhaust pipe clamping devices may need to withstand high temperatures and vibrations, and they may also need to resist corrosion and other types of abrasion.

[0005] In marine applications, exhaust pipe clamps are used to connect and secure various components of exhaust systems, such as manifolds, mufflers, and tailpipes. In these applications, exhaust pipe clamps may need to withstand exposure to saltwater and other harsh marine environments, as well as vibrations and stresses associated with operating vessels or ships. In some cases, marine exhaust pipe clamps may also need to be designed to meet specific regulatory requirements related to emissions and pollution.

[0006] In HVAC applications, exhaust duct clamps can be used to connect and secure ductwork and other components within the ductwork network and exhaust system. This can include connecting exhaust ducts to ventilation fans and connecting other components within the ductwork network and system itself. In these applications, exhaust duct clamps may need to be able to withstand the air pressures and other stresses associated with operating the HVAC system, and they may also need to be designed to meet specific regulatory requirements related to air quality and ventilation.

[0007] However, there are several limitations and potential problems with pipe clamping devices.

[0008] One potential issue is friction. Friction can be significant because it can affect the clamping force and stability of the connection. Overtightening the annular structure of a pipe clamp can increase friction and cause premature failure of the clamp. Similarly, if components of the pipe clamp, such as bolts, nuts, and washers, are not properly positioned, they may fail to provide a secure and stable connection, potentially leading to safety hazards and mechanical problems. Friction can also affect the torque required to tighten or secure the pipe clamp.

[0009] Another important issue may relate to the alignment of pipes and pipe clamps. Proper alignment is crucial for ensuring a proper fit and preventing leaks. If the pipe is not properly aligned with the pipe clamp, stress may be generated in the connection, leading to clamp failure. The temperature of the exhaust gas can also affect the clamping force and stability of the connection; therefore, it is important to select pipe clamps designed to withstand the specific temperature range of the exhaust system.

[0010] For a connection to be both safe and effective, proper installation, alignment, and tightening / secured not only of the pipes and pipe clamps relative to each other, but also of the components of the pipe clamps, is crucial before and during tightening. Proper installation, alignment, and tightening / securedness must also be ensured at high temperatures, such as above 600°C, and at low temperatures, such as below -20°C, and especially along the entire diameter of the pipe clamps.

[0011] Another problem may arise from lateral forces acting on the pipe clamping device. In some applications, the exhaust system may be subjected to lateral forces, side forces, and / or radial forces, such as those encountered during cornering or sudden lane changes. The pipe clamping device should withstand such forces and maintain the alignment of the exhaust system components, preferably always maintaining the alignment of the exhaust system components.

[0012] Furthermore, equal and / or uniform distribution of forces acting on or around the pipe is advantageous, as this helps prevent damage to the pipe and pipe clamps, thereby preventing leaks and / or ensuring a tight seal. For example, some clamps have rubber linings that help absorb vibrations and distribute forces evenly around the pipe.

[0013] International patent application WO 2014 / 071950 A1 describes an exhaust pipe strip clamping device with a flange having reinforcing ribs, wherein fastening devices in the form of bolts and nuts are provided.

[0014] International patent application WO 2006 / 055966 A2 describes a strip clamping device having a strip and nut and bolt fasteners, wherein the head of the bolt has a convex structure that interacts with the flange.

[0015] US Patent Application US 2005 / 0029813 A1 describes a pipe clamping device including a bolt and two hinged portions, the hinged portions being configured as hinged bolts or hinged sleeves.

[0016] Therefore, it is beneficial to provide an improved pipe clamping device, particularly an exhaust pipe clamping device, to prevent, reduce and / or counteract limitations of friction, force distribution, alignment and / or position.

[0017] The subject matter of this invention is defined in the independent claims, while the preferred embodiments of the invention are defined in the dependent claims.

[0018] One aspect of the invention relates to a pipe clamping device comprising: an annular structure configured to receive at least one pipe; the annular structure including a first flange element disposed at one end of the annular structure and a second flange element disposed at the other end of the annular structure; and at least two separate alignment elements configured to be disposed on a fastener for form-fitting engagement with the first flange element and the second flange element, respectively, wherein one of the at least two separate alignment elements has a generally spherical flange engagement shape.

[0019] Another aspect of the invention, which can be combined with any aspect and / or embodiment described herein, relates to a pipe clamping device comprising an annular structure configured to receive at least one pipe; the annular structure comprising a first flange element disposed at one end of the annular structure and a second flange element disposed at the other end of the annular structure; wherein the first flange element and the second flange element comprise respective support structures that extend toward each other and overlap each other, particularly at least partially overlapping each other.

[0020] Another aspect of the invention, which can be combined with any aspect and / or embodiment described herein, relates to a pipe clamping device comprising: an annular structure configured to receive at least one pipe; wherein the annular structure includes at least one fixing structure configured to engage with a protruding edge of the at least one pipe.

[0021] The present invention also relates to a pipe clamping assembly comprising: one or more pipe clamping devices according to the aspects and / or embodiments described herein, and fasteners mounted to a first flange element and a second flange element.

[0022] The present invention also relates to a method for providing positional stability of one or more components during the fastening of one or more components, said one or more components including one or more pipe clamping devices or pipe clamping assemblies according to the aspects and / or embodiments described herein.

[0023] As mentioned above, according to one aspect of the invention, there is a pipe clamping device comprising an annular structure configured to receive at least one pipe.

[0024] A “ring structure” can be understood as an element that can be annular, circular, and / or ring-shaped and can, for example, surround, enclose, enclose, and / or engage with (e.g., engage around) the outer surface of a pipe. The ring structure can have a width, for example, about 0.5 cm to 3.5 cm, particularly 1 cm to 2.5 cm, preferably about 2 cm, in the axial or extending direction of the pipe, and a thickness of about 0.5 mm to 2 mm, particularly 1 mm to 2 mm, preferably about 1 mm. However, other dimensions are possible, depending on the size of the pipe to be received. For example, the ring structure can be made of metal, including, for example, steel composites—including polymers. The ring structure can be formed as a hollow shaft, or, for example, a strip or strip element, or a bent sheet / plate of metal. For example, the pipe can be an exhaust pipe for a vehicle such as a car or motorcycle.

[0025] The annular structure may include a first flange element disposed at one end of the annular structure and a second flange element disposed at the other end of the annular structure. The first and second flange elements may be integrally formed with or separately from the annular structure. The pipe clamping device may also include at least two separate alignment elements configured to be disposed on a fastener to engage with the first and second flange elements in a form-fitting manner, respectively.

[0026] The flange can be, for example, a projecting plate, edge, or collar, and is configured to provide a connection point, for example, for joining two components together. The first and second flange elements can include corresponding holes configured to receive fasteners, wherein the diameter of the holes is larger than the diameter of the fastener. This may result in gaps, such as voids, to allow the fasteners to move more freely during tightening, and thus, for example, lead to improved alignment / positioning and / or reduced friction during tightening. The holes of the first and second flange elements can be coaxially aligned with corresponding holes of at least two separate alignment elements. For example, the fastener can be a bolt or screw, etc.

[0027] A “separate alignment element” can be understood as an element that can be used to engage with one or more components and / or surfaces of one or more components, for example, to: i) accurately, properly and / or precisely ensure the alignment, positioning and / or orientation of these one or more components and / or surfaces; ii) prevent or reduce misalignment, accidental movement / anglement, displacement and / or friction of these one or more components and / or surfaces. Two separate alignment elements according to the embodiments described herein can also allow for a more uniform distribution of forces, for example, around a pipe, during fastening. The reference to “separate” alignment elements can be understood to emphasize that the alignment element is manufactured separately from, for example, other components of the pipe clamping device, i.e., the alignment element is not manufactured integrally with them.

[0028] One of the at least two individual alignment elements may have a generally spherical flange engagement shape. One of the at least two individual alignment elements may be a washer, particularly a spherical washer.

[0029] "Approximately spherical" can be understood as: the flange engagement shape having a curvature very similar to, for example, that of a sphere, a segment of a sphere, a spherical segment, a half-sphere, or a hemisphere, and / or the flange engagement shape having a spherical cross-section. For example, at least one of the individual alignment elements, or both of the other alignment elements, can be a washer with a planar-convex shape, for example, spherically curved on one side along the direction of the flange element (e.g., the flange engagement shape), while on the other side, for example, the opposite side, it is, for example, substantially flat (or planar). Such a washer can be referred to as a spherical washer.

[0030] The other of the two alignment elements can be another washer with a generally spherical flange engagement shape, such as another spherical washer. The other of the two alignment elements can also be a nut, particularly a barrel nut or barrel-shaped nut, wherein, in particular, the nut has a generally cylindrical flange engagement shape. For a barrel nut, it can be threaded, wherein the thread can be perpendicular to the length of the nut. Other shapes of the nut are also possible. In particular, the nut can be a metric thread type with a cylindrical external shape (e.g., barrel-shaped), which can be held in place (when tightened) by means of a mating cylindrical flange from a clamping device.

[0031] For example, alignment elements can be made of metal, such as steel or synthetic materials, including polymers.

[0032] A generally spherical flange engagement shape allows for a larger contact area between the alignment element and the flange element, ensuring a more uniform distribution of force and reducing friction and / or localized stress concentration. With fewer friction points, a much lower torque is required to maintain circumferential tightening force, for example, between the clamping device, the annular structure, and / or the pipe. This further allows for the use of smaller bolts, resulting in lighter pipe clamping devices. Additionally, the curvature of the spherical shape helps align the alignment element with the flange, thus facilitating, for example, precise positioning, orientation, and / or prevention of misalignment, accidental movement / anglement, or displacement of the individual components of the pipe clamping device and / or the pipe clamping device as a whole during installation or operation. This spherical engagement further contributes to, for example, enhancing the stability and rigidity of the connection and reducing the likelihood of movement, vibration, and / or loosening during installation or operation.

[0033] The first flange element and the second flange element may each include a mating portion to receive the at least two individual alignment elements, respectively. Each mating portion may have a shape corresponding to the corresponding flange engagement shape of the at least two individual alignment elements. The mating portions of the first flange element and the second flange element may be bent, particularly concavely, in a direction toward each other. For example, one mating portion may be concavely bent, for example, inwardly, in a direction toward the other mating portion, to receive an alignment element with a convex shape. These aspects may also be applied to the other mating portion. At least one mating portion may have a generally spherical shape. Additionally, both mating portions in the mating portions may have a generally spherical shape. The other mating portion in the mating portions may have a generally cylindrical shape, for example, to receive a barrel nut. Other shapes are also possible.

[0034] The idea that a mating portion has a shape “corresponding” to a flange engagement shape can be understood as meaning that the shape of the mating portion and the flange engagement shape match, customize, adapt, and / or complement each other, for example, in terms of their form, curvature, or shape. For example, a mating portion that abuts, contacts, is oriented to, or engages with a flange engagement shape is formed, adapted, and / or profiled to match, fit, and / or conform to the shape or curvature of the alignment element. For example, if the flange engagement shape (generally spherical) of the individual alignment element is convex or planar-convex, for example, curved outwards in a direction toward the mating portion of the flange element, the corresponding shape of the mating portion of the flange element may also be generally spherical and / or concavely bent or flexed, for example, curved inwards in a direction away from the flange engagement shape, for example, to engage or receive the flange engagement shape. Other shapes, such as cylindrical and / or barrel-shaped shapes, are also possible (see below).

[0035] A first flange element and a second flange element may be arranged between the at least two individual alignment elements. Specifically, the at least two individual alignment elements may engage with the first flange element and the second flange element from opposite sides, respectively. This allows for the prevention or reduction of misalignment, accidental movement / anglement, displacement, and / or reduced friction from both sides on the pipe clamping device, and allows for, for example, maintaining alignment, positioning, and / or orientation during tightening. In this way, the force around the annular structure can also be distributed more evenly. With fewer friction points, a much lower torque is required to maintain circumferential tightening force, for example, between the clamping device, the annular structure, and / or the pipe. This further allows for the use of smaller bolts, resulting in a lighter pipe clamping device.

[0036] According to another aspect of the invention, which can be combined with any aspect and / or embodiment described herein, a pipe clamping device is provided, the pipe clamping device comprising an annular structure configured to receive at least one pipe; the annular structure includes a first flange element disposed at one end of the annular structure and a second flange element disposed at the other end of the annular structure; wherein the first flange element and the second flange element may include corresponding support structures that extend toward each other and overlap each other, particularly at least partially overlapping each other.

[0037] "Support structure" can be understood as a frame, structure, construction, and / or element that provides stability, strength, fixation, and / or support for a pipe clamping device, for example. Support structures can be used to reduce and / or prevent unintentional movement or displacement and / or counteract, for example, lateral / radial forces acting on the pipe clamping device.

[0038] The support structure can be integrally formed with the first flange element, the second flange element, and / or the annular structure, for example, integrally formed as a single piece. For example, the first support structure can be formed by the first flange element, and the second support structure can be formed by the second flange element.

[0039] Each support structure may include at least two lateral segments that can be connected to a base segment. At least two lateral segments of one of the first or second flange elements extend in a direction toward the other of the first or second flange element. The at least two lateral segments of each support structure may, for example, be arranged and connected in a manner substantially perpendicular to the base segment. For example, the lateral segments may project away from the base segment and / or the lateral segments may form substantially right angles or near right angles relative to the base segment. The at least two lateral segments of each respective support structure may extend parallel to each other, for example, maintaining an equal distance or being spaced apart along their length, to create an opening or receiving space between them. For example, when viewed from above (see below), each support structure may be U-shaped, for example, generally U-shaped, wherein the base segment forms the bottom line of the U, and the lateral segments form the vertical lines of the U.

[0040] Additionally, at least two lateral sections of a support structure may taper towards another support structure. For example, the width and / or height of the lateral sections may decrease; for instance, the width and / or height may become smaller or narrower as the lateral sections approach each other. For example, the lateral sections may be triangular or wedge-shaped. This can allow for easier access to components of the pipe clamping device and / or allow for reduced material costs.

[0041] The lateral segments of each support structure may be spaced apart, thereby defining openings or receiving spaces between them. For example, depending on the size of the pipe clamping device and / or the pipe, example spacing may range from 0.5 cm to 4 cm, more particularly from 1 cm to 3 cm, or larger / smaller. The size of the opening or receiving space of one support structure may be larger than the size of the receiving space of the other support structure. For example, one support structure may have larger lateral segments spaced further apart than the lateral segments of the other support structure, resulting in a larger opening. Thus, for example, with respect to the opening thus formed, it can be said that one support structure is larger than the other. The larger opening or receiving space of the support structure may be configured to at least partially surround, enclose, receive, enclose, and / or seal off the other support structure, particularly in the direction toward the other support structure. For example, a larger support structure, such as a lateral segment of the larger support structure, may extend beyond a smaller support structure, such as a lateral segment of the smaller support structure, to enclose the lateral segment of the smaller support structure within the boundary of the lateral segment of the larger support structure, for example, to enclose the lateral segment of the smaller support structure within an opening defined between the lateral segments of the larger support structure.

[0042] Furthermore, when this aspect is combined with the foregoing aspects of the present invention, for example, a corresponding base segment of the corresponding support structure may correspond to a corresponding engagement portion of the corresponding flange element. In such embodiments, these terms may be used interchangeably, or the engagement portion may be located within the base segment.

[0043] According to another aspect of the invention, which may be combined with any aspect and / or embodiment described herein, there is a pipe clamping device comprising an annular structure configured to receive at least one pipe; wherein the annular structure includes at least one fixing structure configured to engage with a protruding edge of the at least one pipe.

[0044] The at least one fixing structure may be integrally formed with the annular structure, particularly integrally formed at the circumferential portion of the annular structure. The at least one fixing structure may include a straight section and a bent section, the straight section extending along the axial direction of the at least one pipe, and the bent section extending substantially perpendicular to the axial direction of the at least one pipe, wherein, in particular, the fixing structure is substantially hook-shaped.

[0045] A “fixing structure” can be a structure, component, and / or element that provides / enhances the stability and fixation of the pipe clamping device, secures the position of the clamping device on one or more pipes and / or prevents movement and / or separation of the pipes, and / or allows for effective clamping and secure fastening to, for example, at least one of the pipes. For example, when two pipes are connected end-to-end, at least partial overlap may occur, wherein one pipe surrounds, encloses, and / or receives the other pipe, which may result in, for example, protruding, bulging, or projecting edges from the ends of the outer pipes.

[0046] The fixing structure, for example due to its hook shape, can engage with the protruding edge to stabilize, maintain, reinforce, fix, secure, and / or retain the position of the pipe clamping device, for example, on at least one pipe. In this way, axial forces / movements acting on the pipe clamping device, for example, in the axial direction of the pipe, can also be counteracted.

[0047] The pipe clamping device described herein can be an exhaust pipe clamping device, wherein, in particular, the first flange element and the second flange element can be integrally formed with the annular structure.

[0048] The pipe clamping device disclosed herein may be a self-aligning pipe clamping device, for example, that aligns itself during clamping, or that aligns itself using one or more of the features described above. Attached Figure Description

[0062] Referring now to various embodiments of the present disclosure, examples of which are illustrated in the figures. In the following description of the figures, the same reference numerals refer to the same parts. Generally, only differences with respect to the various embodiments are described. Each example is provided by way of illustration and is not intended to limit the scope of the disclosure. Furthermore, features of a part illustrated or described as one embodiment can be used in or in combination with other embodiments to produce another embodiment. This description is intended to include these modifications and variations.

[0063] Figures 1A to 1G A pipe clamping device 100 according to some embodiments described herein is shown. It should be noted that... Figures 1A to 1G The pipe clamping device 100 shown does not represent a single embodiment, but rather multiple embodiments. In particular, it is explicitly emphasized that it is not... Figures 1A to 1G Each and every element / feature shown is necessary / required for each embodiment derived from these figures. Conversely, only Figures 1A to 1G Certain features and / or selected elements / components may be used to form one or more embodiments, independent of the other features shown. In this case, those other features may be optional and irrelevant to the corresponding embodiment. For example, Figures 1A to 1G The set of features shown can form the first embodiment, and Figures 1A to 1G The other set of features shown can form a second embodiment different from the first embodiment. The first and second embodiments can also be combined to form yet another embodiment. Figures 1A to 1G A third embodiment may also be shown, which may be independent of other embodiments or may be combined with the first and / or second embodiments, etc. Figures 1A to 1G Elements / components not explicitly mentioned as belonging to a particular implementation should be considered optional.

[0064] Figures 1A to 1G A first embodiment of a pipe clamping device 100 is shown, which includes an annular structure 102 that can be configured, for example, to receive at least one pipe (not shown) in the axial direction 104 of the pipe. Figure 1B In the cross-sectional view, that is, along Figure 1A As can be seen in direction AA, the annular structure 102 may have a shape that substantially corresponds to the shape of at least one conduit to be received, for example, in this case, the shape is circular, annular, and / or ring-shaped. Therefore, the annular structure 102 may be formed, for example, a hollow shaft, or a strip or ribbon element, or a bent metal sheet / plate. The conduit (not shown) may be, for example, an exhaust pipe of a vehicle such as a car or motorcycle.

[0065] As in Figure 1B As can be seen, the annular structure 102 may include a first flange element 106 disposed at one end of the annular structure 102 and a second flange element 108 disposed at the other end of the annular structure 102. Figure 1B As shown, flange elements 106, 108 can be integrally formed with the annular structure 102, for example, integrally formed as a single piece. However, flange elements 106, 108 can be manufactured / produced separately from the annular structure 102, and, for example, attached to the annular structure 102 in a later stage. Flange elements 106, 108 may also include holes, for example openings, to receive fasteners 114 such as bolts or screws.

[0066] According to the first embodiment, the pipe clamping device 100 may further include at least two separate alignment elements 110, 112, which are configured to be arranged on the fastener 114 to engage with the first flange element 106 and the second flange element 108, for example, in a form-fit manner.

[0067] The first flange element 106 and the second flange element 108 may be arranged between the at least two individual alignment elements 110, 112. The at least two individual alignment elements 110, 112 may engage with the first flange element 106 and the second flange element 108 from opposite sides, respectively. For example, as in... Figure 1B As can be seen, the at least two individual alignment elements 110, 112 may include a first alignment element 110, which may be disposed, for example, between the head of the fastener 114 and the first flange element 106, for example, engaging with the first flange element 106, such as on its outer surface. A second alignment element 112 may be disposed, for example, at the end of the fastener 114, for example, engaging with the second flange element 108, such as on its outer surface. The individual alignment elements 110, 112 and... Figures 1A to 1E The other components shown are manufactured separately, that is, not as part of the main components.

[0068] According to the first embodiment, one of the at least two individual alignment elements may have a generally spherical flange engagement shape. (As per...) Figure 1B (Cross-section view along line AA) and Figures 1C to 1D As can be seen, the washer 110 may be a spherical washer 100 and / or the washer may have a planar-convex shape, for example, the planar-convex shape being spherically curved on one side along the direction of a flange, such as the first flange element 106 (e.g., flange engagement shape), while on the other side, such as the opposite side, it is, for example, generally flat (or planar).

[0069] The generally spherical flange engagement shape allows for a larger contact area between the alignment element and the flange, ensuring a more uniform distribution of forces and reducing localized stress concentrations. Additionally, the curvature of the spherical shape aids in aligning the alignment element with the flange, thereby promoting precise positioning, orientation, and / or preventing misalignment, accidental movement / anglement, or displacement, for example, during installation or operation. This spherical engagement helps enhance the stability and rigidity of the connection and reduces the likelihood of movement, vibration, and / or loosening. Furthermore, forces can be distributed more evenly around, for example, the annular structure 102.

[0070] According to a first embodiment, the first flange element 106 and the second flange element 108 may each include corresponding engagement portions 106', 108' for receiving the at least two individual alignment elements 110, 112, respectively, wherein each engagement portion 106', 108' may have a shape corresponding to the corresponding flange engagement shape of the at least two individual alignment elements 110, 112. The engagement portion 106' of the first flange element 106 and the engagement portion 108' of the second flange element 108 may be bent, particularly concavely, in a direction toward each other. For example, the engagement portion 106' may be concavely bent, for example, inwardly, in a direction toward the other engagement portion 108'. At least one engagement portion 106', 108' may have a generally spherical shape. In addition, both engagement portions 106', 108' may have a generally spherical shape.

[0071] The engagement portions 106', 108' that abut, contact, or are oriented to, and / or engage with the corresponding flange engagement shapes (e.g., the flange engagement shapes of the corresponding alignment elements 110, 112) are formed, adapted, and / or profiled to match, fit, and / or conform to the shape or curvature of the corresponding alignment element. For example, as in Figure 1B As can be seen, the flange engagement shape of the individual alignment element 110 is depicted as convex or planar-convex, for example, curved outward in a direction toward the engagement portion 106' of the first flange element 106, for example, generally spherical. Then, the corresponding shape of the engagement portion 106' of the first flange element 106 can also be generally spherical and concave, for example, curved inward in a direction away from the flange engagement shape, for example, to engage or receive the flange engagement shape of the alignment element 110. The above applies to the flange engagement shape of the alignment element 112 and the engagement portion 108' of the second flange element 108.

[0072] For example, as in Figure 1B middle Figure 1DAs can be seen, the individual first alignment element 110 can be, for example, a spherical washer 110 having a generally spherical flange engagement shape, and as in Figure 1E Ideally, the second alignment element 112 can be a cylindrical nut 112, such as a round or barrel-shaped nut, wherein the cylindrical nut 112 can have a generally cylindrical flange engagement shape. For the second alignment element, the engagement portion 108' can have a generally cylindrical shape, for example, to receive a cylindrical or barrel-shaped nut 112. Other shapes of the nut 112 are also possible. For the cylindrical or barrel-shaped nut 112, it can be threaded, wherein the thread can be perpendicular to the length of the nut 112. In particular, the cylindrical or barrel-shaped nut can be a metric threaded nut with a cylindrical external shape (e.g., barrel-shaped), such as... Figure 1H As shown in the perspective view, it can be held in place (during tightening) for example by using mating cylindrical flanges from the clamping device, such as in... Figures 1D to 1G This can be seen in [the image / video]. It should be noted that, as [the image / video]... Figure 1F The 12 mm and 13.5 mm dimensions shown are merely examples; other dimensions can also be envisioned. However, the following will combine... Figures 2A to 2D To explain, the second alignment element 112 can also be another washer 112 having a generally spherical flange engagement shape, such as another spherical washer 112. In other words, Figures 1A to 1G The second alignment element 112 shown is not limited to a cylindrical nut. Instead, the second alignment element can be another spherical washer, or even a nut.

[0073] As in Figures 1A to 1G As further seen, each engagement portion 106', 108' has a shape corresponding to the corresponding flange engagement shape of the at least two individual alignment elements 110, 112. For example, the engagement portion 106' of the first flange element 106 may have a generally spherical shape, for example, to engage with a spherical washer 110, and / or the engagement portion 108' of the second flange element 108 may have a generally cylindrical shape, for example, to engage with a cylindrical nut 112.

[0074] The first flange element 106 and the second flange element 108 may include corresponding holes configured to receive the fastener 114, wherein the diameter of the holes is larger than the diameter of the fastener 114. This may result in gaps, such as voids, to allow the fastener to move more freely during tightening, and thus lead to improved alignment / positioning and / or reduced friction, for example, during tightening.

[0075] like Figures 1A to 1GAs shown, the first flange element 106 and the second flange element 108 can be arranged between the at least two individual alignment elements 110, 112. Specifically, the at least two individual alignment elements 110, 112 can engage with the first flange element 106 and the second flange element 108 from opposite sides, respectively. This allows for prevention or reduction of misalignment, accidental movement / anglement, displacement, and / or reduced friction from both sides on the pipe clamping device 100, and allows for maintaining alignment, positioning, and / or orientation, for example, during tightening; particularly due to the generally spherical flange engagement shape. With reduced friction points, a much lower torque is required to maintain circumferential tightening force, for example, between the clamping device, the annular structure, and / or the pipe. This further allows for the use of smaller bolts, resulting in a lighter pipe clamping device.

[0076] Figures 1A to 1G A second embodiment of the pipe clamping device 100 is shown, which can be combined with any other embodiment and / or aspect described herein, such as the first embodiment above or one or more embodiments below.

[0077] The pipe clamping device 100 according to the second embodiment, which can be combined with any aspect and / or implementation described herein, relates to a pipe clamping device including an annular structure 102 configured to receive at least one pipe (not shown). For example, in... Figures 1A to 1B As can be seen, the annular structure 102 includes a first flange element 106 disposed at one end of the annular structure 102 and a second flange element 108 disposed at the other end of the annular structure 102. Figures 1C to 1G As shown, the first flange element 106 and the second flange element 108 may include corresponding support structures that extend toward each other and overlap, for example, at a point, location, or overlap 120, particularly at least partially overlapping each other. The support structures 116, 118 can be used to reduce and / or prevent unintentional movement, displacement, and / or counteract, for example, lateral / radial forces acting on a pipe clamping device. Figures 1C to 1E As shown, the support structures 116 and 118 can be integrally formed with the first flange element 106 and the second flange element 108 and / or the annular structure 102, for example, integrally formed as a single piece. For example, the first support structure 116 can be formed by the first flange element 106, and the second support structure 118 can be formed by the second flange element 108.

[0078] like Figures 1F to 1GAs shown, each support structure 116, 118 may include at least two lateral segments 116A to 116B, 118A to 118B, which may be integrally or in one piece connected to the base segments 116C, 118C, for example. The at least two lateral segments 116A to 116B of the first flange element 106 extend in a direction toward the second flange element 108, for example toward the lateral segments 118A to 118B of the second flange element 108. The at least two lateral segments 116A to 116B, 118A to 118B, may be integrally connected, for example, and substantially perpendicular to the base segments 116C, 118C. For example, lateral segments 116A to 116B, 118A to 118B may protrude away from base segments 116C, 118C and / or lateral segments 116A to 116B, 118A to 118B may be formed approximately at right angles or near right angles relative to base segments 116C, 118C. The at least two lateral segments 116A to 116B, 118A to 118B may extend parallel to each other, for example, maintaining equal spacing along their length, to form openings 116D, 118D or receiving spaces 116D, 118D between them. For example, when as in Figures 1F to 1G When viewed from the top, each support structure can be in the shape of a "U", for example, roughly U-shaped, wherein the base segments 116C and 118C form the bottom line of the "U", and the lateral segments 116A to 116B and 118A to 118B form the vertical line of the "U".

[0079] As mentioned above, the lateral segments 116A to 116B and 118A to 118B of each support structure 116, 118 may be spaced apart, for example, thereby defining openings or receiving spaces 116D, 118D between them. The size of the opening 116D, 118D or receiving space 116D, 118D of one support structure 116, 118 may be larger than the size of the opening 116D, 118D or receiving space 116D, 118D of the other support structure 116, 118. For example, support structure 118 may have lateral segments 118A to 118B that are spaced further apart than the lateral segments 116A to 116B of support structure 116, thereby creating a larger opening 118D. However, support structure 116 may also be formed to have a larger opening 116D. For example, due to the larger size of the opening 118D, the opening 118D or receiving space 118D of the support structure 118 can be configured to at least partially surround, enclose, and / or seal another support structure 116, such as the lateral segments 116A and 116B of the other support structure 116, for example, at a point, location, or overlap 120, particularly in the direction toward the support structure 116. Therefore, the lateral segments 118A to 118B can extend beyond the lateral segments 116A to 116B to enclose the lateral segments 116A to 116B within the boundaries of the lateral segments 118A to 118B, for example, within the opening 118D of the lateral segments 118A to 118B defined between the lateral segments 118A to 118B. However, the overlap 120 can be smaller or larger, for example, depending on the manner in which the pipe clamping device 100 is fastened at / on a pipe. Preferably, the lateral section should be at least sized such that, for example, once the pipe clamping device is attached, secured, fastened, installed, arranged, stabilized and / or positioned on at least one pipe, there is at least partial overlap.

[0080] In addition, such as Figures 1C to 1EAs shown in more detail, the at least two lateral sections 116A to 116B, 118A to 118B may be tapered and / or inclined. For example, one support structure 116, 118 may be tapered and / or inclined in a direction toward the other support structure 116, 118, for example, in directions 116E, 118E. This tapering / inclination allows the flanges to be aligned and positioned such that the bolts can be relieved of stress from (other) non-axial forces. Additionally, due to the flange design, there may be additional pressure downwards from the flange to the pipe (e.g., on the radial portion of the flange), thus providing a better seal between the clamping device and the pipe. For example, the width and / or height of the lateral sections 116A to 116B may be reduced, for example, the width and / or height becoming smaller or narrower as the lateral sections 116A to 116B approach each other. For example, the lateral sections 116A to 116B, 118A to 118B may be at least partially triangular or wedge-shaped. This can make the components of the pipe clamping device more accessible and / or allow for reduced material costs.

[0081] It should be noted that the second embodiment focuses on the flange elements 106 and 108, and more specifically, on the support structures 116 and 118 formed by the flange elements 106 and 108. Therefore, Figures 1A to 1G The remaining elements / features shown, such as those described in conjunction with the first embodiment and / or other elements / features not explicitly mentioned, may be optional. However, these elements / features may also be combined, for example, with the first embodiment and / or the following embodiments to form yet another embodiment.

[0082] Figures 1A to 1G A third embodiment of the pipe clamping device 100 is shown, which can be combined with any other embodiment and / or aspect described herein, such as the first and / or second embodiments above, or one or more embodiments below.

[0083] According to a third embodiment, a pipe clamping device 100 includes an annular structure 102 that causes to receive at least one pipe (not shown); wherein the annular structure 102 includes at least one fixing structure 122 configured to engage with a protruding edge of the at least one pipe (not shown).

[0084] The at least one fixing structure 122 may be integrally formed with the annular structure 102, particularly at the circumferential portion of the annular structure 102. The at least one fixing structure 122 may include a straight section 122A extending along the axial direction 104 of the at least one pipe and a bent section 122B extending substantially perpendicular to the axial direction 104 of the at least one pipe, wherein, in particular, the fixing structure is substantially hook-shaped.

[0085] The fixing structure 122 provides / enhances the stability and fixation of the pipe clamping device 100, for example, fixing the position of the pipe clamping device 100 on one or more pipes and / or preventing the pipes from moving and / or separating, and / or allowing effective clamping and secure fastening to, for example, the at least one pipe. For example, when two pipes are connected end to end, at least partial overlap can be produced, wherein one pipe surrounds, encloses and / or receives the other pipe, which can create, for example, protruding, projecting, or extending edges from the ends of the outer pipes.

[0086] The fixing structure 122, for example due to its hook shape, can engage with the protruding edge to stabilize, maintain, reinforce, fix, secure, and / or retain the pipe clamping device 100 in position, for example, on the at least one pipe. In this way, axial forces / movements acting on the pipe clamping device, for example, in the axial direction of the pipe, can also be counteracted.

[0087] It should be noted that the third embodiment focuses on the fixing structure 122 formed on the annular structure 102. Therefore, Figures 1A to 1G The remaining elements / features shown, such as those described in conjunction with the first and / or second embodiments, and / or other elements / features not explicitly mentioned, may be optional. However, these elements / features may also be combined with the third embodiment to form yet another embodiment.

[0088] Figures 2A to 2D Another embodiment of the pipe clamping device 100 is shown. Specifically, for example, this embodiment corresponds to the above when the individual first alignment element 110 can be, for example, a spherical washer 110 having a generally spherical flange engagement shape, and the second alignment element 112 can also be another washer 112 having a generally spherical flange engagement shape, for example, another spherical washer 112. Figures 1A to 1G The first implementation method mentioned.

[0089] It should be noted that, Figures 2A to 2D In the embodiments shown, the support structures 116, 118 formed by flange elements 106, 108, and / or, for example, the fixing structures formed on, at, and / or formed by the annular structure 102, are not shown, as in the second or third embodiments discussed above. However, this should not be construed as meaning that the above content cannot be related to... Figures 2A to 2D The pipe clamping device shown is combined. Conversely, with regard to... Figures 1A to 1G The features related to the discussed implementation methods can each be associated with... Figures 2A to 2D The embodiments shown are, for example, combined individually or in combination, to form yet another embodiment.

[0090] Figures 2A to 2D A pipe clamping device 100 is shown, which includes an annular structure 102 that can be configured, for example, to receive at least one pipe (not shown) in the axial direction 104 of the pipe. Figures 2C to 2D As can be seen, the annular structure 102 may have a shape that substantially corresponds to the shape of the at least one conduit to be received, for example, in this case, the shape is circular, annular, and / or ring-shaped. Therefore, the annular structure 102 may be formed, for example, a hollow shaft, or a strip or ribbon element, or a bent metal sheet / plate. The conduit (not shown) may be, for example, an exhaust pipe of a vehicle such as a car or motorcycle.

[0091] As in Figure 2B In the cross-sectional view, that is, along Figure 2A As can be seen in the direction DD, the annular structure 102 may include a first flange element 106 disposed at one end of the annular structure 102 and a second flange element 108 disposed at the other end of the annular structure 102. Figure 2B As shown, flange elements 106, 108 can be integrally formed with the annular structure 102, for example, integrally formed as a single piece. However, flange elements 106, 108 can be manufactured / produced separately from the annular structure 102 and, for example, attached to the annular structure 102. Flange elements 106, 108 may also include holes, for example, openings, to receive fasteners 114 such as bolts or screws.

[0092] The pipe clamping device 100 may also include at least two separate alignment elements 110, 112 configured to be arranged on the fastener 114 to engage, for example, the first flange element 106 and the second flange element 108 in a form-fit manner.

[0093] The first flange element 106 and the second flange element 108 may be arranged between at least two separate alignment elements 110, 112. The at least two separate alignment elements 110, 112 may engage with the first flange element 106 and the second flange element 108 from opposite sides, respectively. For example, as in... Figure 2B As can be seen, the at least two individual alignment elements 110, 112 may include a first alignment element 110, which may be disposed, for example, between the head of the fastener 114 and the first flange element 106, for example, to engage with the first flange element 106, for example, on its outer surface. A second alignment element 112 may be disposed, for example, at the end of the fastener 114, for example, to engage with the second flange element 108, for example, on its outer surface. Individual alignment elements 110, 112 and... Figures 2A to 2D The other components shown are manufactured separately, that is, not as part of the main components.

[0094] One of the at least two individual alignment elements may have a generally spherical flange engagement shape. For example, by... Figure 2B (Cross-section view along the DD line) and Figures 2C to 2D As can be seen, the washer 110 may be a spherical washer 100 and / or the washer may have a planar-convex shape, for example, it is spherically curved on one side along the direction of a flange, such as the first flange element 106 (e.g., flange engagement shape), while on the other side, such as the opposite side, it is, for example, generally flat (or planar).

[0095] The generally spherical flange engagement shape allows for a larger contact area between the alignment element and the flange, ensuring a more even distribution of forces and reducing localized stress concentrations. Additionally, the curvature of the spherical shape helps align the alignment element with the flange, thus facilitating precise positioning, orientation, and / or preventing misalignment, accidental movement / anglement, or displacement, for example, during installation or operation. This spherical engagement helps enhance the stability and rigidity of the connection and reduces the likelihood of movement, vibration, and / or loosening.

[0096] According to a first embodiment, the first flange element 106 and the second flange element 108 may each include corresponding engagement portions 106', 108' for receiving the at least two individual alignment elements 110, 112, respectively. Each engagement portion 106', 108' may have a shape corresponding to the corresponding flange engagement shape of the at least two individual alignment elements 110, 112, for example, a generally spherical shape. The engagement portion 106' of the first flange element 106 and the engagement portion 108' of the second flange element 108 may be bent, particularly concavely, in a direction toward each other. For example, the engagement portion 106' may be concavely bent, for example, inwardly, in a direction toward the other engagement portion 108'.

[0097] As in Figures 2A to 2D As can be seen, the individual first alignment element 110 may be, for example, a spherical washer 110 having a generally spherical flange engagement shape, and the second alignment element 112 may also be a spherical washer 112 having a generally spherical flange engagement shape. A nut 113 may be provided, for example, to transmit force and, for example, to fasten, secure, attach, stabilize, and / or mount the pipe clamping device 100 onto, for example, at least one of the pipes.

[0098] The first flange element 106 and the second flange element 108 may include corresponding holes configured to receive the fastener 114, wherein the diameter of the holes is larger than the diameter of the fastener 114. This may result in gaps, such as voids, to allow the fastener to move more freely during tightening, and thus lead to improved alignment / positioning and / or reduced friction, for example, during tightening.

[0099] like Figures 2A to 2D As shown, the first flange element 106 and the second flange element 108 can be arranged between the at least two individual alignment elements 110, 112. Specifically, the at least two individual alignment elements 110, 112 can engage with the first flange element 106 and the second flange element 108 from opposite sides, respectively. This allows for prevention or reduction of misalignment, accidental movement / anglement, displacement, and / or reduced friction from both sides of the pipe clamping device 100, and allows for, for example, maintaining alignment, positioning, and / or orientation during tightening; particularly due to the generally spherical flange engagement shape. This can also help to distribute forces, such as clamping forces, more evenly around, for example, the annular structure and / or the pipe. For example, with reduced friction points, a much lower torque is required to maintain circumferential tightening force, for example, between the clamping device, the annular structure, and / or the pipe. This further allows for the use of smaller bolts, resulting in a lighter pipe clamping device.
