MOTION RECORDING PROFILE

Description

[0001] The present invention relates to a motion-absorbing profile for attachment to a joint formed between two components. The joint can, in particular, be an expansion joint, which, in order to prevent stress cracks, provides a means of compensating for the unavoidable, material-dependent expansion and contraction of the respective components due to thermal influences. Such joints are particularly necessary in connection with building openings, such as doors or windows. In these areas, the additional challenge lies in the fact that different materials adjoin each other, whose thermal behavior differs due to their different coefficients of thermal expansion.

[0002] A motion detection profile with the features of the preamble of claim 1 is known from US 5,799,456 A. Another motion detection profile, the elements of which are partially magnetically coupled to one another, is disclosed, for example, in CN 201 539 022 U. Furthermore, US 2009 / 0211191 A1 describes how a cover plate can be covered with materials such as carpet, fabric, tiles, wood, or combinations thereof to adapt to adjacent surfaces.

[0003] To achieve the visually appealing impression of a seamless surface while simultaneously preventing the penetration of moisture and foreign matter into the joint, it is advisable to cover the joint. Such a cover can be provided or attached to profiles that may already be installed in the joint area for other purposes. Plaster profiles or facade profiles are examples of suitable construction profiles. Expansion joint profiles can be specifically designed for installation at an expansion joint. Furthermore, reveal connection profiles are also frequently installed in the area of ​​a joint. In principle, however, any profile that can be used to cover a joint, in addition to its other functions, is suitable.

[0004] A particular difficulty arises when covering a joint if it is an expansion joint or if its width changes for other reasons. In the case of a profile bridging the joint, the profile must be able to accommodate the relative movement of the two components forming the joint. The profile itself must therefore possess a certain degree of flexibility or otherwise allow for this movement. The same applies to the joint covering provided by the profile or additionally provided on the profile, especially if the profile and, ideally, also the covering, are to be plastered or otherwise finished in a way that restricts the flexibility or movement of the covering.

[0005] It is an object of the invention to provide a profile that is designed for attachment to a joint formed between two components and, in particular, is designed to accommodate movements of the two components relative to each other, and offers a simple and reliable way of covering the joint, which in particular does not preclude plastering of the profile, preferably including the cover.

[0006] The problem is solved by a motion recording profile with the features of claim 1. Advantageous embodiments of the invention will become apparent from the dependent claims, the present description and the figures.

[0007] The movement absorption profile is designed for installation in a joint formed between two building components. This can be any type of construction profile that allows for movement absorption. In particular, it can be an expansion joint profile or a reveal connection profile. The movement absorption profile comprises a first profile strip designed for attachment to one of the two building components, and a second profile strip designed for attachment to the other. Specifically, the profile strips can have structures designed for attachment to each respective component, such as contact surfaces and edges, as well as openings for fasteners like screws, nails, staples, and the like, and for plaster.

[0008] The motion-absorbing profile further comprises a central section that connects the profile strips and is flexible enough to allow movement relative to each other. The central section, or at least a profile segment of the central section, is preferably designed to be positioned within the joint. The central section preferably connects the two profile strips in that it is connected to both the first and the second profile strip, preferably mechanically, and in particular firmly. Here, "connection" refers not merely to contact between two connected elements, but to a cohesive bond that can be, for example, form-fit, force-fit, or material-fit, and is preferably permanent.The fact that the central area is flexible means, in particular, that it can be significantly and reversibly deformed by forces such as those occurring during the expected movements of the components, without being damaged. This deformability can also be elastic, which can be useful, for example, with regard to sealing the joint.

[0009] The flexibility of the central section connecting the two profile strips allows them to move, at least to a limited extent, relative to each other. It is advantageous if the central section permits at least those relative movements of the profile strips that occur, in particular, due to thermal expansion between the components on which the motion-absorbing profile is mounted. Thus, the relative movements to be permitted are primarily translations and possibly also to some degree of torsion, but generally not rotations.

[0010] Furthermore, the motion-absorbing profile includes a cover strip for concealing the central area and thus, in particular, also for covering the joint into which the central area can advantageously be inserted. It is preferred that the cover strip is arranged such that it completely covers the central area, essentially regardless of the relative position of the two profile strips during their movement, especially when viewed from the outside into the joint parallel to the joint.

[0011] The first and second profile strips, as well as the cover strip, have a particularly elongated structure with at least a substantially constant cross-section. Extending longitudinally perpendicular to the cross-sectional plane, the strips can reach a length of several meters, e.g., 2 m, and can be cut to a desired length or extended by joining several profiles together.

[0012] The cover strip is coupled, or at least connectable, to the first and second profile strips, with the coupling being dependent, in particular, on the current position of the cover strip. The possible movement of the cover strip between different positions is explained below. Preferably, the motion-absorbing profile is designed such that, during normal use, the cover strip is not merely connectable, but always coupled, to at least one of the two profile strips. The respective coupling serves, in particular, to hold the cover strip securely to the profile strip(s) and can, for example, be mechanical.

[0013] However, according to the invention, at least the coupling of the cover strip with the second profile strip is a magnetic coupling. In other words, the cover strip and the second profile strip are designed to be magnetically coupled to each other, whereby this coupling does not necessarily have to be permanent.

[0014] The advantage of magnetic coupling lies particularly in its ability to provide a hold comparable to mechanical coupling while being easily reversible, especially since it can be repeatedly detached and reattached with virtually no wear. Furthermore, magnetic coupling, particularly in the direction perpendicular to the effective attraction of the magnetic elements involved, allows for movement, especially sliding movement, of the coupled elements. The magnetic coupling can be maintained up to a certain degree of movement. Therefore, because the cover strip is magnetically coupled or can be coupled to the second profile strip, the cover strip and the second profile strip can move relative to each other in a corresponding manner to compensate for relative movements of the components forming the joint, without breaking the coupling.In this way, the cover strip can be coupled to both profile strips and always arranged to cover the central area, even though the two profile strips also move relative to each other due to relative movements of the components.

[0015] The connection (permanent connection or coupling capability) of the cover strip to the first profile strip can also be magnetic. Therefore, the cover strip can be held purely magnetically to the two profile strips and rest, so to speak, "floating" magnetically on the profile strips, which are movable relative to each other.

[0016] According to a preferred embodiment, however, the cover strip is mechanically coupled to the first profile strip, for example, by being mechanically hinged to the first profile strip or otherwise mechanically fixed to it. In principle, the cover strip and the first profile strip can also be formed as a single unit, in which case the cover strip is preferably formed by that section of this single-piece element which extends across the joint and, in particular, conceals the central area to the outside. In this way, at least a large part of the joint can advantageously not only be concealed but preferably also plastered over.Since it is sufficient for movement compensation if one of the connections between the cover strip and the two profile strips allows for a corresponding movement, it is advantageous to design the other connection mechanically in order to increase the overall safety and reliability of the cover strip's arrangement on the profile strips. This is because, unlike with two magnetic connections, if at least one mechanical connection is provided, the cover strip cannot so easily detach completely from the profile strips.

[0017] For the aforementioned magnetic coupling, the cover strip and the second profile strip can each have a magnetic element, so that the cover strip is magnetically coupled or can be coupled to the second profile strip by the magnetic interaction of the two magnetic elements. The magnetic element of the second profile strip is, for example, a magnetic strip, i.e., a permanent magnet in strip form, wherein the magnetic strip preferably extends over the entire longitudinal extent of the profile strip. Alternatively to a magnetic strip, several separate, preferably flat, permanent magnets can also be arranged over the longitudinal extent of the profile strip, in particular distributed at a regular rate.The magnetic element of the cover strip is, for example, a strip of sheet steel or a strip of another magnetizable material, in particular a ferromagnetic or ferrimagnetic material, which preferably extends over the entire longitudinal extent of the cover strip. A magnetizable foil can also be provided instead of a magnetizable strip. The arrangement can also be reversed, so that the cover strip has the permanent magnetic element and the second profile strip has at least a magnetizable magnetic element. Furthermore, a permanent magnetic element can be provided on both the cover strip and the second profile strip.

[0018] In principle, the magnetic element can also be integrated into the second profile strip and / or the cover strip. In particular, the cover strip can be made of a material that is itself magnetizable. For example, the cover strip can comprise a hybrid material consisting of a plastic and magnetizable metal components. If the second profile strip then incorporates a permanent magnet as its magnetic element, this magnet can directly attract the cover strip for magnetic coupling.

[0019] Furthermore, it is preferred if the magnetic element of the second profile strip and / or the magnetic element of the cover strip is / are encased. The encasement can be made of, for example, a plastic material. This provides corrosion protection for the magnetic elements. The encasement can also be in the form of a coating, particularly a plastic coating. Alternatively, the encasement can be designed as a shell, e.g., an elongated sleeve, in which the respective magnetic element is received, e.g., inserted.

[0020] Preferably, the magnetic element of the second profile strip is arranged on a projection of the second profile strip that extends beyond the central area. This allows the cover strip to be supported more centrally and therefore more stably than if the magnetic coupling were located laterally to the central area.

[0021] According to an advantageous embodiment, the magnetic coupling between the cover strip and the second profile strip is such that the cover strip, when magnetically coupled to the second profile strip, can be moved relative to the second profile strip while maintaining the magnetic coupling.

[0022] In other words, the cover strip can be moved, at least to a limited extent, without breaking the magnetic coupling. This can be achieved, in particular, by aligning the magnetic coupling appropriately with a relative movement of the two profile strips permitted by the flexible central area, so that the second profile strip can move, in particular slide, not only relative to the first profile strip, but also relative to the cover strip, while remaining magnetically coupled to it.

[0023] The motion-absorbing profile can have a longitudinal extent that corresponds, in particular, to the respective longitudinal extents of the two profile strips and the cover strip, wherein the motion-absorbing profile is designed to be attached to the joint with its longitudinal extent aligned parallel to the joint. According to an advantageous embodiment, when the cover strip is magnetically coupled to the second profile strip, it rests against the second profile strip along an interface that is aligned parallel to the longitudinal extent of the motion-absorbing profile. The cover strip does not necessarily have to be in direct contact with the second profile strip. Preferably, however, the aforementioned magnetic elements of the cover strip and the second profile strip are in direct contact with each other when the cover strip is magnetically coupled to the second profile strip.The cover strip and the profile strip can advantageously be displaced relative to each other along the aforementioned interface, in particular sliding along one another. Therefore, the aforementioned arrangement, with the interface aligned parallel to its longitudinal extent, allows displacements of the second profile strip relative to the first profile strip and relative to the cover strip in the direction of the longitudinal extent. Such an embodiment is therefore particularly advantageous when relative movements of the two components forming the joint are expected in a direction parallel to the joint.

[0024] According to a further advantageous embodiment, at least one of the profile strips has a contact surface designed to rest against one of the two components when the profile strip is attached to that component. When magnetically coupled to the second profile strip, the cover strip rests against the second profile strip along an interface that is aligned parallel to this contact surface. The contact surface of each profile strip rests against the respective component, particularly outside the joint. Preferably, both profile strips each have such a contact surface, and these contact surfaces are preferably aligned parallel to each other, particularly lying in the same plane, so that the aforementioned interface is then parallel to both contact surfaces.Such an orientation of the interface allows movements of the second profile strip relative to the first profile strip and to the cover strip, which occur parallel to the contact surface(s). These movements correspond in particular to relative movements of the components forming the joint towards or away from each other, thereby narrowing or widening the joint.

[0025] With a view to achieving the greatest possible mobility, it is particularly preferred if the interface is aligned both parallel to the longitudinal extent of the motion-absorbing profile and parallel to the contact surface(s) of the profile strips.

[0026] Both the profile strips and the cover strip can each have a surface designed to be plastered. It is particularly preferred that a surface of the first profile strip, a surface of the second profile strip, and a surface of the cover strip are all designed to be plastered. These surfaces are preferably located on the side of each strip that faces away from the respective building components when the movement-absorbing profile is installed. In particular, the surface of each profile strip can be positioned opposite the contact surface of the profile strip, where it rests against the building component when installed. To ensure good plastering adhesion, the surfaces have a specially designed structure that provides good adhesion for the plaster.For example, the surface of the cover strip can be provided with a plaster base tape, e.g., glued or coated. In addition, a screed edge for plastering can be formed on the cover strip, particularly at its end facing the second profile strip, or even on both sides.

[0027] According to the invention, the first profile strip and the second profile strip are not only indirectly connected to each other via the magnetic coupling of the cover strip to the second profile strip and through the central area, but are also coupled or connectable to each other in a further manner, in particular directly, wherein this further coupling is magnetic. The two profile strips can be magnetically coupled in a similar or corresponding manner to that described above for the magnetic coupling of the cover strip to the second profile strip with reference to various embodiments. In particular, one of the two profile strips can have a magnetic element, in particular a magnetic strip, and the other can have a magnetic element, in particular a strip of sheet steel, by whose magnetic interaction the two profile strips are magnetically coupled or connectable.The magnetic elements can each be encased, for example, with a plastic coating to protect against corrosion. An interface between the profile strips, across which the magnetic coupling of the two profile strips occurs, is preferably aligned parallel to a longitudinal extension of the motion-receiving profile and / or parallel to one or more contact surfaces of the profile strips. Furthermore, it is preferred that the two profile strips can be displaced relative to each other along the interface, in particular that they can slide along one another.

[0028] According to an advantageous embodiment, the cover strip is movable between a concealed position, in which it is magnetically coupled to the second profile strip and covers the central area, and an open position, in which it is decoupled from the second profile strip, so that the central area is at least partially accessible. This mobility of the cover strip is preferably retained even when the motion-absorbing profile is mounted. To be movable in this way, the cover strip can, for example, be hinged or pivotally mounted on the first profile strip. Alternatively or additionally, the cover strip itself can be deformable, in particular bendable, foldable, or hinged in a preferably defined manner. In principle, by moving the cover strip into the open position, the central area can be completely exposed, for example, if the cover strip can be opened by 90° or more.However, it is also possible for the open position to differ from the covered position by a significantly smaller angle, for example, by approximately 30° or less. Even then, the central area between the cover strip and the second profile strip can still be sufficiently accessible to, for example, remove foreign objects that have penetrated the joint or the central area, carry out maintenance work, or even lay cables in the joint.

[0029] In this context, it is further preferred that the cover strip has a longitudinal groove, in particular a V-shaped cross-section, and is bendable, foldable, or hinged circumferentially around a valley of the longitudinal groove, especially around the apex of the V-shape, between the covered position and the open position. Overlaps of these movement possibilities are also conceivable. The cross-section is preferably essentially constant over the entire longitudinal extent of the cover strip. One or both of the upper edges of the longitudinal groove, which laterally delimits the longitudinal groove, can project beyond the surface of the cover strip and thereby form edges or at least boundaries for plastering the movement-absorbing profile. In particular, the surface of the cover strip can thus have an edge on both sides between the longitudinal groove and the end of the cover strip pointing towards the second profile strip, facilitating plastering.

[0030] By bending, folding, and / or folding, the cover strip can be moved, particularly between the covered and open positions. Since these movements occur around the valley of the longitudinal groove, the groove is narrowed in each case. In this way, the longitudinal groove can provide the necessary space for movement from the covered to the open position in a defined manner. This is particularly important when the movement-absorbing profile, including the cover strip, is to be plastered, in which case essentially only the longitudinal groove needs to remain free of plaster, while the entire rest of the profile can be plastered. If, on the other hand, the cover strip were hinged to the first profile strip or were simply bent open without the longitudinal groove, the plaster applied there could crack or at least be loosened and damaged. This can be prevented by providing the longitudinal groove.In this way, for example, a wall with an expansion joint, to which the movement absorption profile is attached, can be plastered almost continuously, with the exception of a narrow gap defined by the longitudinal joint, so that the desired impression of an essentially seamless surface is achieved.

[0031] To simplify plastering, it is further preferred that the movement-absorbing profile includes a wedge element designed to be inserted into the longitudinal groove to prevent plaster from penetrating the groove during plastering. Furthermore, the wedge element inserted into the longitudinal groove can also block the cover strip, at least during installation in the cover position. The wedge element preferably comprises a section with a cross-section corresponding to that of the longitudinal groove, so that the longitudinal groove is at least substantially completely filled by the inserted wedge element.

[0032] Retaining elements can be provided, for example at the upper edges of the longitudinal groove and / or at corresponding points on the wedge element itself, to secure the inserted wedge element in the longitudinal groove against unintentional displacement. These can be, for example, constrictions made of soft PVC that extend along a longitudinal line on both sides of the longitudinal groove and hold the inserted wedge element in place by friction. The retaining elements are preferably designed to counteract the gravitational forces acting on the wedge element, but can be overcome manually so that the wedge element can be easily removed from the longitudinal groove after the movement-absorbing profile has been finished. For this purpose, a projection can be formed on the wedge element, allowing it to be pulled out of the longitudinal groove.

[0033] According to a further advantageous embodiment, the central section comprises a profile segment made of a flexible material, in particular soft PVC, which is bent circumferentially around its longitudinal extent, so that it has a U-shape in cross-section. The cross-section is preferably constant at least substantially over the entire longitudinal extent of the motion-absorbing profile. When the central section, in particular the aforementioned profile segment of the central section, is inserted into the joint between the components to which the motion-absorbing profile is attached, the cross-section of the profile segment may also be deformed as a result of being inserted into the joint, preferably retaining at least substantially a U-shape.The U-shape is oriented such that its legs abut each of the other two profile strips or directly against each of the two components forming the joint, and the open side of the U-shape faces the cover strip that covers it. In this way, the interior of the U-shape can be accessed from the outside, particularly by moving the cover strip into the aforementioned open position.

[0034] Furthermore, it is advantageous if the central section projects with a coupling section in the direction of a longitudinal extension of the motion-absorbing profile beyond the profile strips and the cover strip, and is designed to be coupled to the central section of another similar motion-absorbing profile arranged adjacent to the motion-absorbing profile. The motion-absorbing profile is mounted, in particular, with its longitudinal extension parallel to the joint. The coupling section can then project within the joint beyond the remaining motion-absorbing profile to interact with another motion-absorbing profile adjacent in the direction of its longitudinal extension. In principle, the central section can have a coupling section on each side. Preferably, however, a coupling section is provided on only one side.The coupling of the two longitudinally adjacent motion detection profiles can be achieved, in particular, by inserting the coupling section of the central area of ​​one motion detection profile into an interior area of ​​the central area, specifically an interior space of a U-shaped profile section of the central area, of the other motion detection profile. In this way, a continuous channel can be created across several motion detection profiles, extending through the central area of ​​each profile.

[0035] Expansion joints on vertical surfaces, such as walls, typically run vertically (although horizontal or diagonally oriented expansion joints are also possible). In such cases, the movement absorption profiles are preferably installed so that the coupling section protrudes downwards and can thus be inserted from above into the central area of ​​the movement absorption profile below. This prevents any moisture that might flow through the resulting channel from escaping at the joints, instead reliably directing it into the next lower movement absorption profile.

[0036] According to an advantageous further development, the coupling section has a U-shape in cross-section, the legs of which shorten with increasing distance from the rest of the motion-absorbing profile. Simultaneously, the radius of the U-shape can decrease, so that the coupling section tapers conically. However, this is not strictly necessary. Due to the flexibility of the central area, the coupling section with its shortening legs can also simply be bent into a corresponding conical shape. This conical shape of the coupling section then allows it to be inserted into the U-shape of the profile section of the central area of ​​the next identical motion-absorbing profile.

[0037] The invention will be further explained below by way of example only, with reference to the figures. Fig. 1 shows a schematic cross-sectional view of an embodiment of a motion recording profile that is not part of the claimed invention. Fig. 2 shows a schematic cross-sectional view of another embodiment of a motion recording profile that is not part of the claimed invention.

Fig. 5 shows the embodiment shown in Fig. 1 The embodiment shown, which is not part of the claimed invention, is depicted in a schematic perspective view. Fig. 6 shows the embodiment shown in Fig. 1The embodiment shown, which is not part of the claimed invention, is shown in a schematic side view. Figures 7 and 8 show embodiments of the motion-absorbing profile according to the invention in the form of plaster sealing strips in schematic cross-sectional views. Figures 9 to 12 show further embodiments of a motion-absorbing profile, which is not part of the claimed invention, in the form of ceiling sliding bearings in perspective schematic cross-sectional views.

[0038] The in Fig. 1 The motion detection profile 11 shown comprises a first profile strip 13, a second profile strip 15, a flexible central section 17, and a cover strip 19. The motion detection profile 11 is designed to be installed on a surface between two components 43 (only in the Figs. 7 and 8The joint formed (as shown) is arranged such that the two profile strips 13, 15 each bear against a surface 21 of one of the respective components 43 and the central section 17 is received in the joint. The joint can be slightly narrower than the elastic central section 17 shown in its relaxed state, so that the central section 17 is compressed in the horizontal direction (relative to the orientation shown).

[0039] While the profile strips 13, 15 and the cover strip 19 are essentially rigid, the central section 17 connecting the two profile strips is made of flexible soft PVC, allowing the profile strips 13, 15 to move relative to each other and thus accommodate relative movements of the components 43 forming the joint. The profile strips 13, 15 are particularly movable horizontally (relative to the orientation shown) towards and away from each other. In principle, they can also be displaced, at least to a limited extent, relative to each other parallel to the longitudinal extent of the movement-absorbing profile 11 (perpendicular to the plane of the image) and thus to the longitudinal extent of the joint.

[0040] The cover strip 19 is on the one hand (in the Figs. 1 to 4(each on the left) mechanically coupled to the first profile strip 13 and (further to the right) magnetically coupled, or at least connectable, to the second profile strip 15. While the mechanical coupling to the first profile strip 13 is permanent, the magnetic coupling to the second profile strip 15 can be released and re-established, depending on the position of the cover strip 19. Fig. 1 The cover strip 19 is in its covered position, in which it is magnetically coupled to the second profile strip 15 and covers the central area 17. From this covered position, the cover strip 19 can be moved into an open position, which is Fig. 3 shown, whereby Fig. 3 otherwise the Fig. 1This corresponds completely. In this open position, the cover strip 19 is folded out by approximately 30° compared to the cover position, so that it is magnetically decoupled from the second profile strip 15 and the central area between the cover strip 19 and the second profile strip 15 is at least partially accessible from the outside. In order to be movable in this way, the cover strip 19 is in the Fig. 1 , 3 , 5 and 6 In the shown, unclaimed embodiment, the first profile strip 13 is pivotably mounted.

[0041] The magnetic coupling of the cover strip 19 with the second profile strip 15 is effected by cooperating magnetic elements 23, 25. One of these elements is designed as a magnetic strip 23 and is arranged on a projection 27 of the second profile strip 15 that extends beyond the central region 17. The other of these elements is designed as a steel strip 25, which is arranged on the underside of the cover strip 19 and extends over a large part of the underside. The contact area of ​​the two magnetic elements 23, 25 defines an interface that is aligned parallel to the contact surfaces 21 of the two profile strips 13, 15 and parallel to the longitudinal extent of the motion-absorbing profile. The magnetic coupling of the cover strip 19 with the second profile strip 15 occurs across this interface.During a movement of the profile strips 13, 15 parallel to the interface, particularly as a result of a corresponding movement of the two components 43 to which the profile strips 13, 15 are attached, the magnetic elements 23, 25 can be displaced relative to each other in a corresponding manner without breaking the magnetic coupling. In this respect, the steel sheet strip 25 forms a sliding plate for the magnetic strip 23.

[0042] The upward-facing surfaces of the two profile strips 13, 15 and the cover strip 19 shown in the figures are designed to be plastered. For this purpose, the surfaces of the profile strips 13, 15 are structured in a manner typical for plaster profiles and, in particular, have openings through which plaster can pass. In addition, a reinforcing mesh 29 can be attached to each of the profile strips 13, 15, which is only in Fig. 5The surface of the cover strip 19 is specially provided with a plaster base strip, which allows plaster to adhere to the cover strip 19. Furthermore, the cover strip 19 has a drip edge 31 at its free end facing the second profile strip 15, which can be used for plastering and defines the height to which the movement absorption profile 11 is plastered.

[0043] In the Fig. 2 and 4 An alternative, unclaimed embodiment of a motion recording profile 11 is shown. This embodiment largely corresponds to the one in Fig. 1The embodiment shown differs in that the cover strip 19 of the motion-absorbing profile 11 is rigidly connected to the first profile strip 13 and has a longitudinal groove 33 that extends over the entire longitudinal extent of the cover strip 19 and recesses the cover strip 19 in the direction of the central area 17 covered by the cover strip 19. The longitudinal groove 33 has a substantially V-shaped cross-section and is located adjacent to the first profile strip 13. The legs of the longitudinal groove 33 project partially beyond the surface of the cover strip 19 to the same extent as the edge 31. In this way, further reference points are defined for the height to which the motion-absorbing profile 11 is plastered.

[0044] In this unclaimed embodiment according to the Fig. 2 and 4The cover strip 19 is not movable relative to the first profile strip 13 by being pivotable about the connection to the first profile strip 13, but rather by being bendable in the circumferential direction about a valley region 35 of the longitudinal groove 33, which is essentially defined by the lower apex of the V-shape, between the covered position and the open position. For this purpose, the valley region 35 is designed to be flexible. This allows the cover strip 19 to be folded out of the Fig. 2 the shown cover position into an open position, which is, for example, the one in Fig. 4The position shown can correspond to the actual position. Depending on the specific dimensions of the longitudinal groove 33, the cover strip 19 can be opened further or less in the open position compared to the covered position. In the example shown, the open position differs from the covered position by an angle of approximately 15°. However, the angle can also be, for example, up to approximately 20° or up to approximately 30°.

[0045] The motion-receiving profile 11 can have a wedge element 37 which is designed to be inserted into the longitudinal groove 33 in the covering position of the cover strip 19 with a section designed complementary to the longitudinal groove 33, so that the longitudinal groove 33 is completely filled (cf. Fig. 2This prevents plaster from entering the longitudinal groove 33 when the movement-absorbing profile 11 is plastered, which would impair or block the movement of the cover strip 19 between the covered position and the open position. The wedge element 37 has a projection 39 by which the wedge element 37 can be gripped, in particular to easily pull the wedge element 37 out of the longitudinal groove 33 after plastering.

[0046] The central section 17 is essentially formed by a U-shaped profile segment, with each leg of the U-shape firmly connected to one of the profile strips 13, 15. The profile segment, which can, for example, comprise flexible PVC, is flexible enough to be used in joints of varying widths and to adapt to changes in the expansion of the joint into which it is inserted. The U-shaped cross-section of the central section 17 generally allows the interior of the U-shape to be used, for example, for conduits, provided that this does not impair the expansion possibilities of the components 43 forming the joint. Furthermore, it can be advantageous if the interior is accessible for inspection, for example, in the event of damage. Additionally, particularly when the movement-absorbing profile 11 is arranged vertically, moisture, such as condensation, can drain away through this interior space.

[0047] As in the perspective representation of the Fig. 5 and the side view of the Fig. 6 As can be seen, the central section 17, with a coupling section 41, projects on one side in the longitudinal direction via the profile strips 13, 15 and the cover strip 19. The coupling section 41 seamlessly connects to the rest of the central section 17 in terms of its cross-section and therefore also has a U-shape. However, as is particularly evident in Fig. 6It can be seen that the legs of the U-shape become continuously linear with increasing distance from the rest of the motion-receiving profile 11. In this way, the coupling section 41 can be deformed due to its flexibility in such a way that the U-shape has a radius that decreases with increasing distance from the rest of the motion-receiving profile 11 and the coupling section 41 consequently has essentially the shape of a (fully open) lateral surface of a truncated cone, i.e., it tapers conically.

[0048] In this deformed state, the coupling section 41 can be inserted into the interior of a central area 17 of another similar motion-absorbing profile 11, where it advantageously expands again to the extent possible. In this way, a reliable transition between the central areas of flush-mounted motion-absorbing profiles 11 can be achieved. The motion-absorbing profiles 11 are advantageously oriented such that the coupling section 41 projects downwards and is therefore inserted from above into the central area 17 of the next lower motion-absorbing profile 11, so that no moisture can escape downwards at the transition between the motion-absorbing profiles 11.

[0049] How Fig. 5As shown, the reinforcing mesh 29 can project beyond the profile strips 13, 15 and the cover strip 19 in a similar manner to the coupling section 41. This results in an overlap of the reinforcing mesh 29 of adjacent movement-absorbing profiles 11. By jointly plastering the overlapping reinforcing mesh 29, the movement-absorbing profiles 11 are reliably fixed relative to each other.

[0050] Regarding the Figs. 5 and 6 It should also be noted that the motion recording profile 11 is shown in abbreviated form and preferably has a longitudinal extent that exceeds the width of the motion recording profile 11 by a factor of several. For example, the length can be at least about ten times the width. The length can be on the order of meters and be, for example, about 2 m or more, while the width is on the order of decimeters and is, for example, less than about 30 cm, e.g., about 20 cm.

[0051] In the Figs. 7 and 8 The embodiments of a motion-absorbing profile 11 shown in the invention are so-called plaster sealing strips, which are used, for example, to create permanently tight connections between different components 43. These can be, in particular, connections between a window or door profile and the surrounding reveal. In this respect, the motion-absorbing profile 11 can be designed as a reveal connection profile. This applies in particular to the [missing information] Fig. 8 The embodiment shown according to the invention, in which the second profile strip 15 is attached to a component 43 that is not to be plastered (in Fig. 8 left), such as a window or door profile, is attached and the first profile strip 13 is attached to another component 43 to be plastered (in Fig. 8(right) is attached. The first profile strip 13 with its contact surface 21 rests against the component 43 and is designed to be at least partially covered by plaster 45, just like the component 43. The component 43 to be plastered can be, for example, masonry or part of an external thermal insulation composite system.

[0052] Conversely, the first profile strip 13 could also be used for fastening to a component 43 that is not to be plastered, in particular according to the one in Fig. 8 the second profile strip 15 shown, and for this purpose the second profile strip 15 is designed for attachment to a component 43 to be plastered, in particular according to the Fig. 8 The first profile strip 13 shown is formed. Fig. 7A further embodiment of the invention is shown, in which both the first profile strip 13 and the second profile strip 15 are designed for attachment to a component 43 to be plastered and each has a contact surface 21 as well as surfaces oriented opposite to the contact surface 21, which are designed to be plastered. Furthermore, a further embodiment of the invention is conceivable in which both profile strips 13, 15 are each designed in the manner of the Fig. 8 The second profile strip 15 shown is designed for attachment to a component 43 that is not to be plastered.

[0053] The in Figs. 7 and 8The embodiments of the invention shown have in common that the first profile strip 13 and the second profile strip 15 are connected by a central area 17, which is designed as foam. The foam holds the profile strips 13, 15 together, but is at the same time flexible enough to allow a limited relative movement of the profile strips 13, 15 to each other in order to compensate for expansion movements of the components 43. In addition, an additional sealing element 47 is provided, which connects the profile strips 13, 15 in order to seal the joint more reliably than is possible with the foam 17, at least against the ingress of rain or moisture in general. Fig. 8In the embodiment shown according to the invention, the second profile strip 15 is also attached to the respective component 43 via a similar foam. This connection can also include additional sealants suitable for improving the sealing.

[0054] An outwardly directed leg of the essentially Y-shaped cross-section of the first profile strip 13, which largely bridges the joint, forms a cover strip 19, which is located in the Figs. 7 and 8 The embodiments of the invention shown are formed integrally with the first profile strip 13. Figs. 7 and 8The plaster 45 extends only to the joint between the components 43, into which the movement-absorbing profile 11 is inserted. However, it is generally possible to also plaster the outwardly facing (in the figures: upwards) surface of the cover strip 19. For this purpose, the surface of the cover strip 19 can be specially designed, in particular provided with a plaster base strip.

[0055] The cover strip 19 has a magnetic strip as a magnetic element 25, which attracts a magnetic element 23 in the form of a sliding plate provided on the second profile strip 15. In this way, the cover strip 19 and the second profile strip 15 are magnetically coupled to each other, but in such a way that the coupling can be reversibly released and re-established and the cover strip 19 and the second profile strip 15 are movable relative to each other at least parallel to an interface between the magnetic elements 23, 25.

[0056] In addition to this magnetic coupling of the cover strip 19 with the second profile strip 15, and in addition to the connection of the two profile strips 13, 15 via the central area 17, a further direct magnetic coupling of the two profile strips 13, 15 is provided, which in its nature essentially corresponds to the magnetic coupling of the cover strip 19 with the second profile strip 15. For this purpose, the first profile strip 13 has a further magnetic element 51 and the second profile strip 15 has a further magnetic element 49, one of which is designed as a magnetic strip and the other as a magnetically attracted sheet metal strip, in particular a steel sheet strip.The interface between the magnetic elements 49, 51 of this additional magnetic coupling is aligned parallel to the interface between the magnetic elements 23, 25 of the magnetic coupling of the cover strip 19 with the second profile strip 15, so that a corresponding mobility of the two profile strips 13, 15 relative to each other is permitted even with the additional magnetic coupling.

[0057] The in the Figs. 9 to 12The illustrated embodiments of the movement-absorbing profiles 11, which are not according to the invention, can be used in particular as ceiling sliding bearings, for example, in the area of ​​the transition between a concrete ceiling and a masonry structure supporting the concrete ceiling, to absorb relative movements between the components resulting from their differing expansion. Such a movement-absorbing profile 11 can be used in particular at joints between parts of an external thermal insulation composite system (ETICS) that extends across the aforementioned transition. The joint between the components is generally horizontally oriented and is typically largely filled by an insulating strip 53. However, the outside of the joint should be covered as much as possible to prevent the ingress of foreign matter or moisture, especially rain, and should be at least largely plasterable so that the joint is as inconspicuous as possible.

[0058] The usable ones, in the Figs. 9 to 12 The motion-absorbing profiles 11 shown each have a first profile strip 13 and a second profile strip 15, which are arranged on opposite sides of the insulation strip 53. Preferably, the insulation strip 53 is glued to one of the two profile strips 13, 15. In order to mechanically connect the two profile strips 13, 15 directly to each other, a central area 17 is also provided in each case, which is located in the Figs. 9 to 12 is trained differently.

[0059] At the in Fig. 9 In the illustrated, unclaimed embodiment, the central region 17 is designed as a membrane, the material of which is, in particular, flexible PVC. The central region 17 of the in Fig. 10The illustrated, unclaimed embodiment comprises two lamellae provided on the first profile strip 13, between which a further lamella provided on the second profile strip 15 is inserted. The lamellae of the first profile strip 13 are preferably made of flexible PVC, while the lamella of the second profile strip 15 is preferably made of rigid PVC. In principle, the lamellae can also be arranged in the opposite order on the first and second profile strips 13 and 15. Furthermore, more than the aforementioned lamellae can be provided on the two profile strips 13 and 15, with the respective number preferably differing by at most one. The interlocking lamellae preferably force-fit the first profile strip 13 and the second profile strip 15 together.

[0060] At the in Fig. 11In the illustrated, unclaimed embodiment, the first profile strip 13 and the second profile strip 15 are connected by a central section 17 designed as a further flat strip, which is pivotally coupled to the two profile strips 13 and 15. The pivotal coupling can, for example, be achieved by means of a strand of flexible PVC. The central section 17 of the Fig. 12 The illustrated, unclaimed embodiment is formed by two spirally bent end sections of the two profile strips 13, 15, which interlock. This interlocking structure provides a positive connection between the profile strips 13, 15, while allowing movement of the profile strips 13, 15 relative to each other, particularly about a central axis of the structure.

[0061] In the Figs. 11 and 12In the unclaimed embodiments shown, in addition to the central area 17, a joint sealing tape 55 is arranged between the first profile strip 13 and the second profile strip 15 to specifically seal the profile strips 13 and 15 against each other. The joint sealing tape 55 can, in particular, be a so-called compression tape, which is pre-compressed and expands automatically after installation to fill the available space and thereby create a particularly reliable seal. Such a joint sealing tape 55 can also be used in principle in the embodiments shown in Figs. 9 and 10 The embodiments shown, which are not claimed, are additionally provided.

[0062] The two profile strips 13, 15 each have a contact surface 21 with which they can abut against respective building components 43, e.g., elements of an external thermal insulation composite system. The contact surface of at least the first profile strip 13 has several openings through which plaster 45 can penetrate when plastering the building components 43. This ensures that the respective profile strip 13, 15 is reliably attached to the respective building component 43.

[0063] Furthermore, in all four in the Figs. 9 to 12In the illustrated, unclaimed embodiments, a cover strip 19 is provided which is mechanically pivotally coupled to the first profile strip 13. The coupling is achieved via a strand of flexible PVC that connects the cover strip 19 to the profile strip 13 and, due to its elasticity, acts as a hinge. However, other types of mechanical coupling are also conceivable. Due to the pivotal coupling with the first profile strip 13, the cover strip 19 is positioned between an open position, in which it provides access to the joint or the central area 17, and the area enclosed in the Figs. 9 to 12The respective cover positions shown are movable. In the cover position, the cover strip 19 is coupled not only to the first profile strip 13, but also to the second profile strip 15, with the coupling to the second profile strip 15 being magnetic. This coupling is based on the magnetic interaction between a magnetic element 23 arranged on the second profile strip 15 and a further magnetic element 25 arranged on the cover strip 19. The magnetic element 23 of the second profile strip 15 is designed as a magnetic strip, while the magnetic element 25 of the cover strip 19 is designed as a magnetically attracted sliding plate.

[0064] The surfaces of the first profile strip 13, the second profile strip 15, and the cover strip 19, which point away from the respective component 43 and opposite the contact surfaces 21, are specially designed to be plastered. Furthermore, a free end of the cover strip 19 is angled relative to the rest of the cover strip 19 and thus projects forward in such a way as to form a screed edge 31 for plastering. In order to obtain a defined finish for the plaster 45 to be applied to the side of the second profile strip 15, and advantageously also to prevent the plaster 45 from reaching the magnetic element 23 or even the central area 17, a plaster edge 57 projecting from the second profile strip 15 can also be provided, which is arranged particularly in the area between the cover strip 19 and the second profile strip 15.
