Prior art

[0002] Positioning devices for drywall construction, which can be attached to the underside of metal profiles using a magnet, are known from the prior art. These devices allow the position of the metal profile to be aligned using a laser level. For this purpose, markings are arranged on the broad sides of these positioning devices, which are designed, for example, as laser targets.

[0003] Known laser targets have an L-shape, so that only two broad surfaces of the long leg of the L, pointing away from each other, serve as a target surface for the usually rotating laser beam of commercially available laser leveling devices.

[0009] WO 2008 / 119583 A1 discloses a marking device with an L-shaped structure consisting of a mounting section and a projection section arranged at right angles to each other. The mounting section has a flat contact surface with an adhesive layer for detachable attachment to an object, while the projection section projects at right angles from the object. Summary of the invention

[0010] The invention is based on the objective of further developing known positioning devices for fastening metal profiles to a supporting structure for drywall construction in a way that is advantageous for practical use by means of a laser leveling device.

[0011] The problem is solved by the invention specified in the claims, wherein the dependent claims not only represent advantageous further developments of the device specified in claim 1, but are also independent solutions to the problem.

[0012] First and essentially, a positioning device is provided with a base body that has an end plate with a face designed to establish a magnetic connection to the metal profile. A side plate is arranged perpendicular to the end plate, having a side surface on which a first scale is arranged. The first scale can, for example, include measuring lines extending over the entire side surface and / or only partially across the side surface. The measuring lines can, for example, be 31363N1PCT drg / drag / ha 14 October 2025 The laser targets are arranged on the broad side surface. Furthermore, according to the invention, at least one narrow plate is provided, arranged perpendicular to the broad side plate and perpendicular to the end plate. A second scale is arranged on at least one of the broad side surfaces of the narrow plate, which also has one or more measuring lines that can be used to align the positioning device using a laser level. The measuring lines arranged on the broad side surfaces of the broad side plate and the narrow plate can extend over the entire width of the broad side surface or only over a portion of it. It is also possible for only some of the measuring lines, all of the measuring lines, or none of the measuring lines to extend over the entire broad side surface. The measuring lines can each run in a common horizontal plane with one or more measuring lines of the first scale.The measurement lines of the first and second scales can also merge into one another.

[0013] Due to this narrow plate and the markings arranged on it, an additional target surface is available for the laser beam of the laser level, especially the rotating laser beam. This allows the laser level to be positioned at almost any location within the room where the metal profiles are to be attached to the ceiling, as one of the two scales can be targeted or struck by the laser beam from any direction in the room. The device has a lightweight design with minimal mass.

[0014] In a first embodiment of the invention, the narrow plate can be arranged centrally between the wide edge edges of the wide side plate and centrally between the narrow edge edges of the end plate. This gives the base body a T-shape in cross-section. The measuring lines of the second scale can be arranged vertically one above the other. Each measuring line 31363N1PCT drg / drag / ha 14 October 2025 It can be arranged within a common horizontal plane with one or more measurement lines of the second scale. The measurement lines of the first and second scales run at right angles to each other.

[0015] Preferably, measuring lines can be arranged on both broad surfaces of the narrow plate and the broad side plate. In this way, at least four different target surfaces are available for the laser level.

[0016] The end plate of the positioning device can accommodate one or more magnets, which allow the device to be attached, in particular, to the underside of a metal profile. The magnets can, for example, be inserted into recesses or openings in the end plate. Alternatively, the entire surface of the end plate can be made of a magnetic material or have a magnetic coating. The broad faces of, for example, two disc-shaped magnets can be flush with the end plate. The magnets can be clamped in the openings of the end plate. Alternatively, the entire surface of the end plate can be made of a magnetic material or have a magnetic coating. The broad faces of, for example, two disc-shaped magnets can be flush with the end plate.The broad surfaces of the magnet can also be arranged offset from the front surface of the end plate.

[0017] In a second embodiment of the invention, the narrow panel can be arranged adjoining a broad edge of the broad panel. A broad edge of the narrow panel can connect to the broad edge of the broad panel, forming a vertex line. This leads to 31363N1PCT drg / drag / ha 14 October 2025 to an L-shaped base body of the positioning device. The edge edges of the wide-side plate and the narrow plate extending along the apex line can be longer than the edge edges of the wide-side plate and the narrow plate extending perpendicular to it. The wide-side plate and the narrow plate thus each have a rectangular shape.

[0018] In a further embodiment of the invention, a broad edge of a narrow plate can be connected to each of the two broad edges of the broad side plate, so that the base body has a U-shaped cross-section. The broad edges of the broad side plate and the narrow plates can be connected to each other, forming a vertex line. The measuring lines of the first and second scales can be connected to each other in the region of the vertex line.

[0019] The measuring lines of the first and second scales can preferably run parallel to the edge edges of the end face. However, additional measuring lines can also be provided that run parallel to the broad edges of the narrow or broad side plate.

[0020] The first scale can have a first measuring line extending over the entire length of the broadside plate and a second measuring line arranged perpendicular to it, extending over the entire width of the broadside plate. The first and second measuring lines can intersect at a point located in the center of the broadside plate. One or more circular measuring lines can run around the point of intersection in a target-like pattern. The circular measuring lines can be arranged coaxially with each other. 31363N1PCT drg / drag / ha October 14, 2025

[0021] The plates forming the base body of the positioning device, i.e., the end plate, the side plate, and the one or more narrow plates, preferably have the same material thickness. The material thickness of the plates can be less than 15%, in particular less than 10% or 5%, of the width of the end plate.

[0022] The panels can preferably be made of a rigid material, especially plastic. The panels can be made, for example, of a clear, translucent, or opaque material.

[0023] Furthermore, an adapter element may be provided. The adapter element may have a first flat side and a second flat side facing away from the first flat side. A connecting element, particularly nail-shaped, for connecting to a profile, especially a wooden profile, to be attached to a supporting structure for drywall construction may be assigned to the first flat side. The nail-shaped connecting element may, in particular, project beyond the end face 5 in a direction facing away from the side panel. The adapter element is preferably plate-shaped. In particular, the first flat side and the second flat side may be arranged parallel to each other.

[0024] The second flat side of the adapter element can be equipped with a ferromagnetic element for magnetic connection to the magnet, thus creating a simple and detachable connection between the adapter element and the base body. The adapter element can be made of plastic.

[0025] Alternatively, the adapter element can be made of a ferromagnetic material. 31363N1PCT drg / drag / ha 14 October 2025

[0026] The connecting element itself can be made of a ferromagnetic material, making the connecting element suitable not only for connection with the profile but also for connection with the magnet.

[0027] In a preferred embodiment, the base body can be formed in two parts. In particular, the base body can comprise a first base body element and a second base body element that is detachably connected or connectable to the first base body element. The two base body elements are preferably connected or connectable to each other along a dividing plane, which is arranged, in particular, parallel to the broad side plate. A recess or opening for the magnet is preferably arranged in the end plate, wherein the magnet is held in the end plate by a form-fit and / or force-fit in a connected state of the base body elements, and the magnet can be removed from and / or inserted into the recess in a separated state of the two base body elements.

[0028] The magnet can be interchangeable with a connecting element, particularly a nail-shaped one, for connecting to a profile to be attached to a supporting structure (1) for drywall construction. In this way, the magnet, as a magnetic connecting element with ferromagnetic materials, can be exchanged for a nail-shaped connecting element for connecting to a flexible profile, such as a wooden profile.

[0029] It is also possible that the magnet has a first end with a nail-shaped connecting extension for attaching to a profile to a drywall support structure, and a second end, facing away from the first, with a flat side. The magnet is then 31363N1PCT drg / drag / ha 14 October 2025 The end plate can be attached in such a way that the flat side is for magnetic connection with a metal profile to be attached to a drywall support structure, or the nail-shaped connecting extension is for connection with a profile to be attached to a drywall support structure. It is then easily possible to adapt the positioning device for attachment to profiles made of different materials.

[0030] According to a further embodiment, the end plate can have a through-opening for the passage of a screw or nail for connection to a profile, in particular a wooden profile, to be attached to a supporting structure for drywall construction. The through-opening can extend in the main direction of the broad side plate.

[0031] According to a further embodiment, two connecting parts can be provided for connection to a flexible, in particular band-shaped, attachment element. At least one of the two connecting parts can be detachably connected or connectable to the attachment element. If one connecting part is detachably connected or connectable to the attachment element, the other attachment element is preferably permanently connected to the attachment element, i.e., only detachable by destruction. The attachment element is specifically designed to detachably fasten the positioning device to the metal profile.

[0032] Each connecting element is preferably associated with a narrow plate (13, 13'), particularly in the upper third associated with the end plate, preferably a quarter, more preferably a fifth, more preferably a tenth, of the narrow plate and / or directly in the area of ​​the end plate. 31363N1PCT drg / drag / ha 14 October 2025

[0033] A reflective film can be applied to the base body, particularly the broadsides, to improve the visibility of a laser beam. The reflective film can be white, resulting in particularly good visibility regardless of the laser color used. Alternatively or additionally, the reflective film can also be a different color or be multicolored. The reflective film can be printed with a design, particularly lines, and / or have at least one marking to facilitate precise positioning on the base body or the broadside(s). Alternatively or additionally, the first and / or second scale can be applied to the reflective film. Brief description of the drawings

Description of the embodiments

[0035] Figure 1 shows an example of a support structure 1 for drywall construction 1, attached to a ceiling 24. A positioning device 3 is provided to align the position of a metal profile 2, which is to be attached to the support structure 1, using a laser level 23. The positioning device 3 is detachably attached to the underside of the metal profile 2. The positioning device 3 and the laser 23 can assume any relative position (see Figures 2 and 3). The laser 23 is preferably a rotary laser with a rotating prism that deflects the laser beam by 90°, thus creating a reference plane. The reference plane is shown here in an example horizontal orientation.

[0036] In Figures 1 and 2, the positioning device 3 is shown in an exemplary first rotational position relative to the laser 23, in which the laser beams strike a broadside plate 7 of the positioning device 3 head-on. A first scale 9, 10, 11, 11', 12, comprising various measuring lines, is arranged on a broadside surface 8 of the broadside plate 7. The position of the metal profile 2 is aligned by aligning one or more measuring lines along the reference plane generated by the laser 23. 31363N1PCT drg / drag / ha October 14, 2025

[0037] According to the invention, in addition to the broad side plate 7 and an end plate 5 arranged perpendicular to it, at least one narrow plate 13, 13' is provided, arranged perpendicular to the broad side plate 7 and perpendicular to the end plate 5. A second scale 15, which also comprises several markings, is arranged on a broad side surface 14 of the narrow plate 13, 13'.

[0038] Figures 1 to 6 show a first embodiment of the positioning device 3 according to the invention, in which the narrow plate 13 is arranged centrally between the broad edge edges 16, 16' of the broad side plate 7 and centrally between the narrow edge edges 17, 17' of the end plate 5. If the positioning device 3 assumes a rotational position, as shown by way of example in Figure 3, in which the laser beams emitted by the laser 23 strike not only the broad side plate 7 but also the narrow plate 13, 13', the alignment of the position of the metal profile 2 can be carried out both on the basis of the first scale 9, 10, 11, 11', 12 arranged on the broad side surface 8 of the broad side plate 7, and on the basis of the scale on the broad side surface 14 of the narrow plate 13, 13'.Due to the additional projection surface provided by the narrow plate 13, 13' perpendicular to the broad side surface 8 of the broad side plate 7, the alignment of the position of the metal profile 2 is possible independently of the relative position of the positioning device 3 and the laser 23 in space. Therefore, it is not necessary to change the position of the laser 23 in space and / or the position of the positioning device 3 in order to target one of the two scales.

[0039] As shown in Figure 4, magnets 22 are arranged in the end plate 5 of the positioning device 3 for the detachable attachment of the positioning device 3 to the metal profile 2. Two magnets 22, each mounted in a recess 32 of the end plate 5, are shown as an example (see also Figure 6). However, fewer or more magnets 22 can also be used in the end plate 5. 31363N1PCT drg / drag / ha October 14, 2025 The magnets 22 can be arranged in the openings in a clamping fit. They can be inserted into the opening from the concave side of the end plate 5, which is opposite the end face 6. A projection can extend from the end face 6 into the opening, against which the magnet is supported. Other magnetic means can also be provided, such as a magnetic film that extends partially or over the entire end face 6 of the end plate 5. In addition, non-magnetic fastening means can also be provided to attach the positioning device 3, in particular to the underside of the metal profile 2.

[0040] Figure 5 shows a frontal view of the broadside surface 8 of the rectangular broadside panel 7. Various measuring lines of the first scale 9, 10, 11, 11', 12 are arranged on the broadside surface 8 of the broadside panel 7. A first vertical measuring line 10 extends over the entire length of the broadside panel 7. Perpendicular to the first measuring line 10, a second horizontal measuring line 12 is arranged, extending over the entire width of the broadside panel 7. The first measuring line 10 and the second measuring line 12 intersect at a point of intersection located in the center of the measuring panel 7. Two circular measuring lines 11, 11' are arranged coaxially around the point of intersection. In addition, a plurality of measuring lines 9 running parallel to the second measuring line 12 are provided, each extending over less than a quarter of the width of the broadside panel 7.The measuring lines 9 shown in Figure 5 extend, by way of example, from the broad edge edges 16, 16' of the broad side panel 7 over approximately one-sixth of the width of the broad side panel 7. An end of the measuring lines 9 pointing away from the broad edge edges 16, 16' is spaced apart from the radially outermost circular measuring line 11. Two of these measuring lines 9 are arranged in a common horizontal plane, each adjoining one of the two broad edge edges 16, 16'. 31363N1PCT drg / drag / ha October 14, 2025.

[0041] As shown in Figure 6, the second scale 15 arranged on the broad side 14 of the narrow plate 13 comprises a plurality of parallel measuring lines that extend essentially across the entire width of the narrow plate 13. Not shown is the broad side opposite the broad side 14 of the narrow plate 13 shown in Figure 6, which also comprises a second scale 15 with a plurality of parallel measuring lines. The second scale 15 can also have measuring lines extending across the entire length or only a portion of the length of the narrow plate 13. The second scale 15 can also have crosshair-shaped measuring lines.

[0042] Figures 7 and 8 show a second embodiment of the positioning device 3 according to the invention. The narrow plate 13 is arranged on one of the broad edge edges 16 of the broad side plate 7, with a broad edge edge 18 of the narrow plate 13 being connected to the broad edge edge 16 of the broad side plate 7 by forming a vertex line 19. This results, as can be seen in Figure 8, in an L-shaped cross-section of the positioning device 3. The edge edges 16, 18 of the broad side plate 7 and the narrow plate 13 extending along the vertex line 19 are longer than the edge edges 20, 20', 21, 21' of the broad side plate 7 and the narrow plate 13 extending transversely to them.

[0043] The measuring lines of the second scale 15 are connected to the measuring lines 9, 12, which extend over the entire width or only a portion of the width of the side panel 7, in the area of ​​the vertex line 19. This allows the alignment of the metal profile 2 in a rotational position of the positioning device 3, as shown in Figure 3, to be carried out simultaneously along interconnected measuring lines of the first scale 9, 12 and the second scale 15. 31363N1PCT drg / drag / ha October 14, 2025

[0044] Figure 9 shows a third embodiment of the invention. The positioning device 3 comprises two narrow plates 13, 13', each of which connects with one of the wide edge edges 18, 18' to one of the wide edge edges 16, 16' of the wide side plate 7, forming a vertex line 19, 19'. This gives the positioning device 3 a U-shaped cross-section.

[0045] As in the second embodiment, the measuring lines of the first scale 9, 12 are connected to the measuring lines of the second scale 15 in the region of the vertex lines 19, 19'. The positioning device 3 thus forms a hollow body open on one of its broad sides.

[0046] The broad side plate 7, the end plate 5, and the narrow plates 13, 13' preferably have the same material thickness. The material thickness of the plates is preferably less than 10% of the width of the broad side plate. The end face 6 of the end plate 5 is smaller than the broad side face 14 of the narrow plate 13 and smaller than the broad side face 8 of the broad side plate 7, wherein the broad side face 14 of the narrow plate 13 is smaller than the broad side face 8 of the broad side plate 7.

[0047] Figures 10 and 11 show a further embodiment of the invention. In this embodiment, the positioning device 3 has an adapter element 25 for connection to the base body 4, in particular the end plate 5. The adapter element 25 is preferably magnetically connectable to the base body 4, as will be explained below.

[0048] The adapter element 25 is preferably plate-shaped. The adapter element 25 preferably has a first flat side 26 and a second flat side 27 facing away from the first flat side 26. The two flat sides 26, 27 are preferably arranged parallel to each other. 31363N1PCT drg / drag / ha 14 October 2025 The extent of the flat sides 26, 27 can correspond at least essentially to the extent of the end plate 5 or end surface 6.

[0049] The adapter element 25 has at least one connecting element 28, in particular nail-shaped, for connecting to a profile, in particular a wooden profile 29, to be attached to a supporting structure 1 for drywall construction. The connecting element 28 is preferably associated with the first flat side 26. In the embodiment shown in Figs. 10 and 11, the adapter element 25 has two connecting elements 28. The connecting element 28 can be pressed into the profile, in particular a wooden profile 29, by applying a compressive force to establish a connection with it. To release the connection, the adapter element 25, together with the connecting element 28, can simply be pulled off the profile 29 in the opposite direction.

[0050] As shown in Fig. 11, a ferromagnetic element 30 can be assigned to the second flat side 27 for connection with the magnets 22. In this way, the adapter element 25 can be connected to and detached from the base body 4 in a particularly simple manner.

[0051] Alternatively, the connecting element 28 can also be made of a ferromagnetic material. In this case, a separate ferromagnetic element 30 is not necessary to establish a magnetic connection between the base body 4 and the adapter element 25. The connecting element 28 is then designed as a multifunctional part, which, in addition to connecting to the profile 29, is also designed to connect the adapter element 25 to the base body 4. 31363N1PCT drg / drag / ha October 14, 2025

[0052] Figures 12 and 13 show a further embodiment of the invention. As Figures 12 and 13 show, the base body 4 can be formed in two parts. The base body 4 can have a first base body element 4' and a second base body element 4''.

[0053] The two basic body elements 4', 4'' can be detachably connected or connectable to one another. The two basic body elements 4', 4'' can be connected or connectable to one another along a parting plane T. The parting plane T can, in particular, be arranged parallel to the broad side plate 7 and / or broad side surface 8. The connection between the basic body elements 4', 4'' can, in particular, be effected by means of snap-fit ​​connection elements 31, which are designed to form a detachable connection between the two basic body elements 4', 4''.

[0054] The parting line T can divide the recess 32 in the middle.

[0055] As further shown in Figs. 12 and 13, the end plate 5 has a recess 32 for each magnet 22. In the connected state of the base body elements 4', 4'' shown in Fig. 12, the magnets are held in the end plate 5, in particular the recess 32, by a form-fit and / or force-fit. In the separated state of the two base body elements 4', 4'' shown in Fig. 13, the magnets can be removed from the recess 31 or inserted into the recess 32.

[0056] The magnet 22 can be interchangeable with a nail-shaped connecting element 28, as shown in Fig. 13. It is then possible, after separating the two base body elements 4', 4'' from each other, to remove the magnet 22 and replace it with a nail-shaped connecting element 28. 31363N1PCT drg / drag / ha 14 October 2025 Insert the recess 32. After connecting the two base body elements 4', 4'', the positioning device 3 can then be reliably attached to a wooden profile 29. The interchangeability of the magnet 22 with the nail-shaped connecting element 28 allows for a particularly wide and diverse range of applications for the positioning device 3.
