Description

[0001] The present invention relates to a mounting unit for a flagpole, comprising a base unit for anchoring in the ground, which extends along a central axis, a receiving unit for receiving the flagpole, and a guide unit with at least one pivoting unit for pivoting the receiving unit in a direction transverse to the central axis to assist in erecting and lowering the flagpole. The invention further relates to a flagpole system and a method for erecting a flagpole system.

[0002] Various brackets, and especially tilting brackets, for flagpoles are known from the prior art. These brackets primarily consist of a mounting plate and a ground anchor. The ground anchor is embedded in a foundation. It has a mounting plate that extends across the ground perpendicular to the vertically oriented center axis of the erected flagpole. The mounting plate also has a mounting plate. When erecting the flagpole, the mounting plate of the mounting plate is positioned on the mounting plate of the ground anchor. The plates can then be connected with several screws distributed around the circumference. To facilitate erection of the flagpole, both plates can have eyelets along their edges, which can be aligned with each other using a bolt.

[0003] To erect the flagpole, the mounting bracket is swiveled, and the horizontal flagpole is threaded onto it. The flagpole is then raised using the bracket. The eyelets provide support and prevent the mounting plates from shifting relative to each other as the long flagpole is raised. At least two people are required for erection to ensure proper guidance from all sides while raising the flagpole and to support each other. Furthermore, at least one person must secure the erected flagpole against tipping while the second person screws the mounting bracket to the ground anchor. It is crucial that both people do not obstruct each other.This is the main reason why the costs for mounting such a bracket and erecting a flagpole with such a bracket represent a significant portion of the total costs for manufacturing and operating such a flagpole system. These total costs include not only the costs for mounting the bracket, but also the labor costs for erecting the flagpole and the costs for manufacturing the bracket itself. Additional costs may also be included in the total costs.

[0004] It is therefore the object of the present invention to provide a mounting unit for a flagpole, a flagpole system and a method for erecting it, which has lower overall costs than the mountings known from the prior art.

[0005] The problem is solved by a mounting unit with the features of claim 1, a flagpole system with the features of claim 11, and a method for erecting a flagpole of a flagpole system with the features of claim 12. Preferred embodiments are the subject of the dependent claims. Further properties and features will become apparent from the general description and the description of the exemplary embodiment.

[0006] The mounting unit according to the invention for a flagpole comprises: a ground unit for fixing in a ground, which extends along a central axis, in particular a substantially vertical one; and a receiving unit for receiving the flagpole; and a guide unit with at least one joint unit for pivoting the receiving unit in a direction transverse to the central axis to assist in erecting and lowering the flagpole.

[0007] The joint unit can be accommodated inside the flagpole. Preferably, the joint unit is arranged and designed such that it can be accommodated inside the flagpole. Advantageously, the joint unit can be accommodated inside the flagpole when it is erected.

[0008] The invention has many advantages. A significant advantage is that the joint unit can be accommodated within the flagpole, meaning that the joint unit can be positioned inside the flagpole during erection. This allows the forces acting on the flagpole during raising and lowering to be advantageously transferred to the ground unit. A force transmission via a screw connection between the mounting unit and the ground anchor is no longer necessary. Simultaneously, the joint unit can assist a person in raising the flagpole and guide its movement. Once erected, the flagpole, held in the mounting unit, can be lowered so that it encloses the joint unit, which is then contained within the flagpole.Simultaneously, the joint unit is centrally located in the area of ​​the base unit's central axis, ensuring that the forces exerted during flagpole erection are reliably absorbed and transferred by the mounting unit. Furthermore, the pivoting of the joint unit can be limited or locked by its connection within the flagpole. Advantageously, only a single person is required to erect a flagpole using the mounting unit according to the invention. Additionally, the centrally located joint unit allows for material savings, as the large and heavy mounting plates are no longer necessary. This results in significantly lower overall costs compared to such mountings known from the prior art. Because no mounting plates are required, essentially only the flagpole is visible when erected.The mounting unit is therefore also secure against vandalism, since parts such as the joint unit are not accessible when the flagpole is erected.

[0009] In particular, the flagpole is at least partially hollow. Advantageously, this allows the joint unit to be accommodated within the flagpole. Specifically, the at least partially hollow flagpole is designed as a profile mast. Preferably, the profile mast can be designed as a profile with one or more chambers, preferably hollow chambers. Alternatively, the hollow flagpole can advantageously also be designed as a tubular flagpole, preferably as a round tube or the like. A further alternative is that the flagpole can include a hollow section or, preferably, a tall adapter in which the joint unit can be accommodated. Preferably, the joint unit is designed as a single-axis fork joint. Advantageously, the single-axis fork joint is pivotable about a pivot axis transverse to the central axis with a corresponding pivoting direction transverse to the central axis.Advantageously, pivoting perpendicular to the pivoting direction is not possible and is prevented by the geometry of the joint. Advantageously, the single-axis fork joint allows forces acting perpendicular to a pivoting direction to be transmitted directly through the joint unit into the base unit. This effectively prevents the flagpole from tipping perpendicular to the pivoting direction, especially during erection. The centrally located joint unit also results in a short lever arm for the forces acting on the flagpole, allowing these forces to be safely and effectively transferred through the joint unit into the base unit. This results in a significantly higher static load-bearing capacity compared to existing, prior art mountings. During erection, the flagpole is guided, specifically by positive force.

[0010] The guide unit preferably comprises a linear guide unit. In particular, the linear guide unit is arranged between the joint unit and the receiving unit. The receiving unit, especially with the flagpole it holds, is displaceable relative to the joint unit and the base unit, particularly along a linear axis of movement. In particular, there is a positive-locking connection between the linear guide unit and the flagpole it holds. Advantageously, the linear guide unit enables guided displacement of the flagpole relative to the joint unit and the base unit. Advantageously, the linear guide unit comprises a first guide element and a second guide element, wherein the second guide element can be received on the first guide element, particularly by a positive-locking connection. Advantageously, the first guide element can be designed as an elongated slot.In particular, the second guide element can comprise a connecting unit. Preferably, the second guide element is designed as a bolt, especially as a threaded bolt with a nut for positive engagement with the first guide element. Advantageously, the receiving unit is slidably mounted and, in particular, supported on the linear guide unit. Advantageously, the first guide element, designed as an elongated hole, allows the erected flagpole to be lowered in a controlled manner so that the joint unit can be received inside the flagpole. Advantageously, the guide unit enables guidance, in particular positive guidance, of the movement. The guide unit, comprising in particular the joint unit and the linear guide unit, can therefore also be referred to as a positive guidance unit.

[0011] Advantageously, the receiving unit can include a receiving element, particularly in the form of a sleeve or the like, onto which the flagpole can be precisely positioned. In particular, the flagpole can be slid and / or attached to the receiving element. Preferably, the receiving element has several compensating elements that compensate for tolerances between the flagpole and the receiving element so that the flagpole can be attached to the receiving unit with little or no play. Preferably, the compensating element is designed as a ring attached to the receiving element. Advantageously, the compensating elements are made of a plastic, particularly polyoxymethylene. Advantageously, the receiving unit can be lowered, particularly in an upright position, so that the joint unit and / or at least parts of the base unit are contained within the receiving unit and, in particular, within the flagpole.Advantageously, the recording unit enables the recording and dissipation of the forces of the flagpole during its movement, especially when erecting or laying it down.

[0012] In particular, the joint unit and base unit can be accommodated at least partially within the mounting unit. Advantageously, forces introduced into the flagpole can thus be directly transferred to the base unit. Preferably, the diameter of at least part of the base unit and / or the joint unit is smaller than the inner diameter of the mounting unit, and especially of the flagpole, so that the base unit can also be partially accommodated within the flagpole. Advantageously, this relieves the load on the guide unit, at least in the erected state, allowing for the use of thinner materials and reducing manufacturing costs.

[0013] Preferably, the articulated unit has a stop position in which at least one movement of the receiving unit is locked. In the stop position, the receiving unit, and in particular one flag axis of the received flagpole, extends essentially in the direction of the central axis. Advantageously, the stop position allows the received flagpole to be first erected by a single person and then lowered in a controlled manner, so that the articulated unit, and in particular a part of the base unit, can be received into the flagpole.

[0014] Advantageously, in the stop position, movement of the receiving unit, and in particular the linear guide unit, is locked. Specifically, the stop position can be set when the receiving unit is pivoted beyond a position in which the flag axis is parallel to the central axis during the erection of the flagpole. In other words, the receiving unit, and in particular the flagpole, is pivoted beyond a vertical alignment of the flag axis to reach the stop position. In the stop position, the flag axis has an angle to the central axis of between 2 degrees and 15 degrees, particularly between 3 degrees and 10 degrees, and preferably in the range of approximately 5 degrees. In the stop position, the joint unit is also preferably locked and cannot be pivoted further along the pivot direction for erection.

[0015] Advantageously, the stop position defines a defined holding point during erection. A person erecting the flagpole can hold it in the stop position, particularly before lowering it by the linear guide unit. This makes erection even more convenient. From the stop position, a person can pivot the flagpole back from the stop position so that the flag axis is essentially parallel, and especially coaxial, with the central axis of the base unit. In this position, a receiving unit guided by a linear guide unit is movable again. The receiving unit, especially along with the flagpole, can then be advantageously lowered by the linear guide unit so that the steering unit and, in particular, the base unit can be accommodated within the receiving unit and, especially, within the flagpole.The stop position of the joint unit advantageously allows the process of setting up and laying down to be divided into different defined sections, making setting up and laying down even more convenient for a single person.

[0016] The base unit advantageously includes a mounting stop. Preferably, the mounting stop defines a level up to which the base unit is recessed within the ground, such that an upper end of the base unit and also the joint unit protrude from the ground, particularly a foundation. In particular, the mounting stop is located at a distance of at least 100 mm to 500 mm from the joint unit. Preferably, the mounting stop is located at a distance of at least 200 mm to 300 mm, and particularly preferably approximately 250 mm from the joint unit. Advantageously, the distance is chosen such that the forces from the flagpole can be permanently and reliably transferred to the base unit. Furthermore, a person lowering the flagpole only needs to lift the flagpole itself by this distance to then lower it. A height of approximately 250 mm has proven particularly advantageous in this regard.In particular, the distance between the mounting stop and the joint unit can generally be up to 10 percent or even 20 percent of the length of the flagpole.

[0017] In particular, a locking unit for securing the erected flagpole is included. Specifically, the locking unit comprises a threaded bolt and nut, as well as an opening on the flagpole and on the mounting unit. Advantageously, the locking unit secures the erected flagpole to the mounting unit in such a way that it cannot be pulled upwards, particularly by vertical winds acting on a flag, or similar forces. Specifically, the flagpole is secured in the lowered position, in which the joint unit and, in particular, a part of the base unit are housed within the flagpole.

[0018] The base unit preferably comprises a base sleeve and an insert. Preferably, the insert can be inserted into the base sleeve. In particular, the insert is designed as a tube, preferably as an inner support tube. In particular, the insert is connected to the joint unit, preferably directly. The base unit most preferably includes an alignment unit. In particular, the alignment unit allows adjustment of the orientation of the insert about the central axis, preferably of the joint unit, and especially preferably of the pivoting direction of the joint unit relative to the base sleeve. The orientation can be set in increments between 5 degrees and 45 degrees, preferably between 10 degrees and 30 degrees, and most preferably in 15 degrees.This is particularly helpful when erecting and lowering the flagpole, especially when space is limited at the installation site, particularly if trees, buildings, or similar obstructions block the erection or lowering direction. Furthermore, the alignment unit allows for the alignment of the base unit's central axis. Ideally, the alignment unit includes alignment elements for this purpose. Alternatively, the base unit can be a single piece and fixed directly into the ground. This option is particularly cost-effective.

[0019] In particular, an adapter unit is included. Advantageously, the adapter unit serves to compensate for any play between the receiving element of the receiving unit and the insert of the base unit. Advantageously, the adapter unit at least partially encloses the insert. In particular, the adapter unit comprises at least one adapter element. In particular, the adapter element is designed as a tubular element. Preferably, the adapter unit is made at least partially of an elastic, compliant material, preferably polyoxymethylene (POM). Advantageously, the adapter unit is arranged at least partially between the base unit, in particular the insert, and the receiving unit, in particular the compensating element. Advantageously, the adapter unit is designed such that at least the adapter element is compressed between the base unit and the receiving unit in the erected position of the mounting unit.In its intended use, the adapter unit preferably fills the gap between the insert and the receiving element, creating a play-free, positive-locking connection between the ground sleeve and the receiving element. The advantage of using an adapter unit is that the compensating unit can be designed to accommodate and / or compensate for manufacturing tolerances in the steel tubes, thus preventing excessive play in the system, which could cause the flagpole to sway. Furthermore, a compensating unit made of polyoxymethylene offers significant advantages when erecting and lowering the flagpole due to its much lower friction. This ensures even safer and faster assembly and / or disassembly of the flagpole.

[0020] Further advantageous developments and properties result from the overall general description and from the description of the exemplary embodiment.

[0021] The flagpole system according to the invention comprises a previously described mounting unit and a flagpole, which in particular is received at least at the mounting unit.

[0022] The flagpole system according to the invention also has many advantages. A significant advantage of the flagpole system is that, due to the central arrangement of the joint unit and, in particular, the forced guidance provided by the guide unit, it can be erected and lowered by a single person. This significantly reduces the overall costs compared to solutions known from the prior art. Further advantageous developments and properties of the flagpole system will become apparent from the general description and the description of the exemplary embodiment.

[0023] The inventive method for erecting a flagpole of a previously described flagpole system by a single person comprises at least the following method steps: In particular, moving the articulated unit into a pivoted position, especially by pivoting the receiving unit transversely to the central axis, preferably by an angle of 90 degrees or more to the central axis; and threading the horizontal flagpole onto the receiving unit, and in particular securing the flagpole, preferably to a linear guide unit; and erecting the flagpole by one person by pivoting the articulated unit, and in particular the flagpole received on the receiving unit; and lowering the flagpole so that the articulated unit, and in particular the base unit partially, are received inside the flagpole, and preferably inside the receiving unit; and in particular securing the flagpole in the erected position by a locking unit.

[0024] In particular, the articulated unit is moved into a stop position during the erection process. Specifically, the receiving unit, and especially the flagpole, are moved beyond a vertical position into this stop position during erection, thus preventing any movement of the receiving unit with the flagpole, and especially any linear guide unit connected to it. Subsequently, the receiving unit, especially with the flagpole, can be lowered from the stop position into the erected position in a controlled manner by pivoting it back, i.e., pivoting it back against the direction of pivoting during erection. Specifically, this pivoting back occurs through a small angle, as described above.

[0025] The method according to the invention also has many advantages. A significant advantage of the method is that it can be carried out by a single person. The movement of the flagpole is guided by the control unit, allowing a single person to erect the flagpole comfortably.

The same reference numerals are used for identical or similar parts and for parts with identical or similar functions.

[0027] It is not necessary for a holding device and / or a flagpole system and / or a method according to the invention to have all the features described below. It is also possible for a holding device and / or a flagpole system and / or a method according to the invention to have only individual features of the embodiment described below.

[0028] Fig. 1 Figure 1 shows a schematic perspective view of a mounting unit 100 according to the invention in a pivoted position V of a joint unit 31 and a receiving unit 2 for receiving the flagpole 101. The mounting unit 100 comprises a base unit 1 for fastening in a ground 103. The base unit 1 extends along a substantially vertical central axis 17. A receiving unit 2 for receiving the flagpole 101 is also provided. The flagpole 101 is tubular in this case. The receiving unit 2 comprises a receiving element 21, which is designed as a sleeve 21 and has compensating elements 22 made of polyoxymethylene (POM), which are designed as rings 22 and are received on the sleeve 21.

[0029] Furthermore, a guide unit 3 is provided. The guide unit 3 comprises the joint unit 31 and also a linear guide unit 32. The joint unit 32 enables the receiving unit 2 to pivot in a pivoting direction transverse to the central axis 17 to assist in erecting and lowering the flagpole 101.

[0030] The joint unit 31 is designed and arranged here such that it can be accommodated within the tubular flagpole 101. The central arrangement of the joint unit 31 advantageously allows the forces exerted during the erection and lowering of the flagpole 101 to be transferred through the joint unit 31 into the base unit 1. Here, the joint unit 31 is further designed as a single-axis fork joint 31, thus providing a defined pivoting direction. Tilting perpendicular to the pivoting direction is prevented by the positive guidance provided.

[0031] Here the linear guide unit 32 is arranged within the receiving unit 2, so that the receiving unit 2 is movable and displaceable relative to the joint unit 32 and the base unit 1.

[0032] The base unit 1 comprises a base sleeve 15, an insert 14 held in the base sleeve 15, and an alignment unit 16 for aligning the pivot direction of the joint unit 32 to align the position of the central axis 17 of the base unit 1. The base unit 1 also includes an installation stop 11, which is arranged at a distance 18 of approximately 250 millimeters from the joint unit 32. Accordingly, the insert of the base unit 1 protrudes from the base 103.

[0033] Fig. 2 Figure 1 shows a schematic perspective view of the mounting unit 100 according to the invention with the joint unit 32 in pivoted position V with a flagpole 101 positioned thereon. The flagpole 101 extends along a flag axis 1011 and has an inner diameter 1012. The inner diameter 1012 of the flagpole 101 is larger than the outer diameter 23 of the receiving unit 2 and has a diameter 12 of the base unit and a diameter 33 of the joint unit 31.

[0034] Fig. 3 Figure 1 shows a schematic perspective view of the mounting unit 100 according to the invention with the flagpole 101 mounted in a pivoted position V. The flagpole 101 is positively connected to the mounting unit 100 by a connecting unit 34 of the linear guide unit 32, which is designed here as a screw connection.

[0035] Fig. 4 Figure 1 shows a schematic perspective view of the mounting unit 100 according to the invention in a stop position AS of the joint unit 32. By moving the single-axis joint unit 31 in the pivoting direction, the flagpole 101 can be erected. In stop position AS, movement of the receiving unit 2 is blocked, so that the receiving unit 2 cannot be lowered by the linear guide unit 32. In stop position AS, there is a small angle of approximately 5 degrees between the central axis 17 and the flag axis 1011. From this stop position AS, the flagpole 101 can be lowered in a controlled manner into an erected position A by pivoting back, so that the joint unit 31 and part of the base unit 1 are contained within the flagpole 101.For this purpose, the diameter 12 of a receptable part of the ground unit 1 is smaller than the inner diameter 1012 of the flagpole 101 and the inner diameter 24 of the receiving unit 2. Alternatively, the flagpole 101 can also be laid down.

[0036] Fig. 5 Figure 1 shows a schematic perspective view of the mounting unit 100 according to the invention during the lowering of the flagpole 101 into the erected position A. After being raised, the flagpole 101 is lowered by the guide unit 2 by pivoting back from the stop position AS. During this process, the joint unit 31 and part of the base unit 1 are accommodated within the flagpole 101 and within the receiving unit 2. Advantageously, forces introduced into the flagpole 101 can then be directly transferred to the base unit 1. The receiving unit 2 and the base unit 1 do not need to be screwed together via plates, so that the mounting unit 100 has a diameter that essentially corresponds to the diameter of the flagpole 101.

[0037] Fig. 6 Figure 1 shows a schematic perspective view of the mounting unit 100 according to the invention, wherein the flagpole 101 is secured in the erected position A by a locking unit 4. The locking unit 4 comprises a threaded bolt 41 designed as a screw 41 and a nut 42. The screw is guided through a bore passing through the flagpole 101 and the mounting unit 100 and secured with the nut, so that the flagpole 101 can no longer move relative to the mounting unit 100.

[0038] Fig. 7 Figure 1 shows a schematic perspective detail view of the base unit 1, including a base sleeve 15, an insert 14, and an alignment unit 16. The base sleeve 15 can be mounted in a base 103. The insert 14 is received in the base sleeve 15. Part of the alignment unit 16 serves to align the base unit 1 relative to the joint unit 32. The lugs of the alignment unit 16 engage in a corresponding contour in the base sleeve, allowing for adjustment of the angular position of the insert 14 and the alignment of the pivot direction of the joint unit 32 relative to the base unit 1. Furthermore, the alignment unit 16 includes an alignment ring as an alignment element. The alignment ring allows for the alignment of the central axis 17 of the base unit 1, which is defined by the insert 14.

[0039] Fig. 8 Figure 1 shows another schematic perspective view of the ground sleeve 15 with part of the alignment unit 16 from below. The inserted star-shaped contour, into which the lugs on the insert 14 of the alignment unit 16 can engage, is visible here. The orientation of the insert 14 can be adjusted in 45-degree increments. This also allows for adjustment of the pivot direction of the joint unit 31.

[0040] Fig.9 Figure 1 shows another schematic perspective view of part of the alignment unit 16. Here, the alignment ring for aligning the central axis 17 of the base unit 1 is shown in detail. Alignment of the central axis 17 is achieved by screws that define the position of the insert 14 and thus the central axis 17 of the base unit 1. The alignment of the central axis 17 is particularly relevant because it also influences the alignment of the flag axis 1011.

[0041] Fig.10 shows another schematic perspective view of the mounting unit 100 with the joint unit 31 in pivoted position V.

[0042] Fig. 11 Figure 1 shows a schematic perspective detail view of the linear guide unit 32 and the receiving unit 2. The linear guide unit 32 extends from the depicted lower part of the joint unit 31. The guide unit 32 includes an elongated hole. The receiving unit 2 can be mounted on the linear guide unit 32 of the guide unit 3. A connecting unit 34 allows the flagpole 101 to be connected to the receiving unit 2 and the linear guide unit 32 (see figure 3). Fig. 12

[0043] Fig. 12 Figure 1 shows a schematic perspective view of a mounting unit 100 in its erected position A, where the flagpole 101 is not attached to the mounting unit 2. The mounting unit 2 is connected to the linear guide unit 32 by the connecting unit 34.

[0044] Fig. 13 Figure 1 shows a schematic perspective view of a flagpole system 102 in its erected position A, with the base unit 1 fixed in the ground 103. Due to the positive guidance of the guide unit 2, the mounting unit 100 has a small diameter, which here is smaller than the outer diameter of the flagpole 101. Base plates extending over the ground 103, as known from the prior art, are no longer necessary. This also significantly minimizes the risk of injury. The mounting unit 100 and the flagpole system 102 according to the invention have many advantages over the prior art: In particular, the mounting unit 100 enables safer erection and lowering of the flagpole system 102. This is advantageously facilitated by the possibility of arranging the joint unit 32 inside the flagpole 101.This is further advantageously facilitated by the guidance, preferably forced guidance, of the movement of the flagpole 101 during erection and / or lowering. It is advantageous that erection and / or lowering can be carried out by a single person. Furthermore, it is advantageous that the orientation of the flagpole, and thus in particular the direction of rotation, can be adjusted by the alignment unit 16, preferably in 45-degree increments, especially after the ground sleeve 15 has been firmly mounted in the ground 103, preferably embedded in concrete. Furthermore, it is advantageous that when the flagpole 101 is erected, only the flagpole 101 itself and, if anything, a small part of the ground unit 1 are visible, and in particular, no mounting plates are present. This results in a particularly aesthetically pleasing appearance for the flagpole system 102.Furthermore, a joint unit 32 integrated within the flagpole 101 is particularly well protected against damage, especially vandalism. Moreover, a mounting unit 100 and a flagpole system 102 according to the invention have lower overall costs. Fig. 14 Figure 1 shows a schematic perspective sectional view of another embodiment of a holding unit 100 according to the invention. In the sectional view, the receiving element 21 of the receiving unit 2 is located vertically above the insert 14 of the base unit 1 for lowering. An adapter unit 19 is also present. The adapter unit 19 is attached to the insert 14 of the base unit 1. The adapter unit 19 comprises a tubular element made of polyoxymethylene (POM). The adapter unit 19 is attached to the insert 14. In the erected position A, the adapter unit 19 is located between the insert 14 and the receiving element 21 of the receiving unit 2. The receiving element 21 surrounds the adapter unit 19.In its intended use, the adapter unit 19 can fill the gap between the insert 14 and the receiving element 21 in such a way that a play-free, force-fit connection exists between the ground sleeve 15 and the receiving element 21. The receiving element 21 and the ground sleeve 15 are each made of hot-dip galvanized steel. This improves force transmission between the ground sleeve 15 and the receiving element 21. Fig. 15 Figure 1 shows a schematic sectional view of a further embodiment of the mounting unit 100 according to the invention. The mounting unit 100 is shown here in the same position as in Figure 2. Fig. 14The adapter unit 19 is screwed to the base sleeve 15. The adapter unit 19 has an outer diameter 191, which essentially corresponds to the inner diameter 24 of the receiving element 21. In an advantageous embodiment, the outer diameter 191 of the adapter unit 19 attached to the insert 14 is slightly larger, for example by a few tenths of a millimeter, particularly at temperatures of approximately 20 degrees Celsius. Advantageously, this results in a small temperature-dependent clearance between the compensating element 21 and the insert 14 over a wide temperature range, which is common, especially in Central Europe.
