[0002] Set of devices for passing lines, pipes and / or cables through a building component

[0003] Technical area

[0004] The invention relates to a set of devices comprising a plurality of devices for passing lines, pipes and / or cables through building components, such as building walls, building ceilings and the like, and measures for preventing the passage of fire gases and smoke through such devices.

[0005] Technical background

[0006] During installation, it is common for several lines, pipes, and / or cables to be divided into bundles, which are then routed through individual fixtures and sections of the building. Depending on the specific application, the quantities of lines, pipes, and / or cables to be routed through the building sections vary in both number and size, making it difficult to achieve optimal loading of the available fixtures.

[0007] It is known from practice to combine several identically designed devices in a mounting flange or frame.

[0008] Because only one size of fixture can be arranged in a frame, some applications may not be optimally loaded when installed, which can lead to undesirably low loads for individual fixtures and potentially undesirable sealing. Furthermore, some applications may require an undesirably large mounting cross-section due to the uniform size of the fixtures.

[0009] The object of the present invention is to provide a set of devices for passing lines, pipes and / or cables through a part of a building, with which an optimized loading level with a high level of sealing can be achieved in a simple manner for various applications.

[0010] Disclosure of the invention

[0011] This object is achieved by the set of devices comprising at least two devices for passing lines, pipes and / or cables through a building part according to claim 1.

[0012] Further embodiments are specified in the dependent claims.

[0013] According to one aspect of the invention, a set of devices is provided, comprising at least two devices for leading lines, pipes and / or cables through a building part, each having a housing with a housing wall, wherein the housing has an axial passage channel which is delimited by the housing wall and runs in the longitudinal direction and which has an opening at each of the opposite ends, wherein the devices have a length in the longitudinal direction and each have a rectangular cross-section arranged perpendicular to the longitudinal direction and having a width in a transverse direction and a height in a vertical direction, wherein a first device has a first width, a first height and a first length and a second device has a second width, a second height and a second length.

[0014] According to the invention, it is provided that a ratio of the height of the second device to the height of the first device is n1 / x1, where n1 and x1 are from the set of natural numbers and are not identical, and / or a ratio of the width of the second device to the width of the first device is n2 / x2, where n2 and x2 are from the set of natural numbers and are not identical, and where the at least two devices are detachably connectable to one another.

[0015] The proposed solution has the advantage that, by providing fixtures with different cross-sections, an optimized loading level with a correspondingly high level of sealing can be easily achieved for the respective application. Furthermore, due to the different sizes of the fixture set, the total installation cross-section required for an application can be easily reduced compared to a design with identical fixtures.

[0016] The dimensions of the devices are selected in particular in such a way that different devices can be fitted into a frame or mounting flange with a defined height and a possibly variably adjustable width and essentially completely fill a receiving space or an internal cross-section of the frame in the assembled state.

[0017] In an advantageous embodiment of a set of devices according to the invention, it is provided that a ratio of the second height H2 to the first height H1 is 1 / 1, 1 / 2, 1 / 3, 1 / 4 or 2 / 3, and / or that a ratio of the second width B2 to the first width B1 is 1 / 1, 1 / 2, 1 / 3, 1 / 4 or 2 / 3. This makes it easy to fully utilize a feedthrough cross-section of a frame and, at the same time, provide devices of different sizes for the respective applications.

[0018] It is particularly advantageous if the set of devices includes at least a third device with a length, a width and a height, wherein a ratio of the third height to the height of the first device or to the height of the second device is 1 / 1, 1 / 2, 1 / 3, 1 / 4 or 2 / 3. Alternatively or additionally to this, at least a third device with a length, a width and a height can be provided, wherein a ratio of the width of the third device to the width of the first device or to the width of the second device is 1 / 1, 1 / 2, 1 / 3, 1 / 4 or 2 / 3. Any desired number of devices can be provided, wherein at least two, but also three or more different dimensions can be provided. The greater the number of devices with different dimensions, the easier it is to achieve a cross-sectional area optimized for the respective application.

[0019] In an advantageous embodiment of a set of devices, at least one device has a square cross-section. For example, two devices with different square cross-sections can be used, with the height and width of the smaller device preferably being 1 / 3 or 2 / 3 of the height and width of a larger device.

[0020] Alternatively, devices with a rectangular cross-section can also be used, whereby a ratio of a width to a height of a device can in principle be selected as desired and the one or more further devices have a height to width ratio adapted thereto.

[0021] Particularly preferably, the lengths of the devices of the set of devices are substantially identical.

[0022] In order to enable easy attachment of the devices to a wall or ceiling, the set of devices can have a frame which is intended for attachment to a wall or ceiling and which defines a receiving space or internal cross-section intended for loading, in which at least two devices can be arranged. The frame can, for example, have a height corresponding to a device or, in particular, a multiple of the height of a device in the set of devices, for example, twice or three times the height of a device. The frame is particularly preferably adjustable, so that, in particular, a width of the internal cross-section exposed by the frame can be adjusted. Alternatively or additionally, a height of the cross-section exposed by the frame for the arrangement of devices can also be adjustable.

[0023] In an advantageous embodiment of a set of devices according to the invention, it is provided that the at least two devices each have at least one connecting region for interconnection, wherein at least one separate connecting element is provided by means of which the at least two devices can be detachably connected to one another in the connecting regions. This enables a simple and reversible connection of two devices. Preferably, all devices in the set can be connected to one another using identically constructed connecting elements.

[0024] In a structurally simple embodiment of the invention, the separate connecting element can be connected to the two devices in a clip-like manner. Preferably, the separate connecting element assumes a locked state when connected to two connecting areas of two different devices, thus reliably protecting it against accidental release. It can be provided that the separate connecting element, when connected to two devices, is connected to the connecting area of ​​the respective device, which has an undercut.

[0025] In an advantageous embodiment of the invention, the separate connecting element has a central receiving area, which is provided for jointly enclosing a wall area of ​​a first device and a wall area of ​​a second device. The receiving area has a thickness that essentially corresponds to twice the wall thickness of the devices.

[0026] To ensure a secure connection of the connecting element to two devices, the separate connecting element can have two legs, one leg of the separate connecting element being designed to lock with one device and the other leg of the separate connecting element being designed to lock with another device. During a connection process of the connecting element to two devices, the two legs of the connecting element are prestressed perpendicular to an insertion direction of the connecting element in order to lock with end regions of the legs behind wall regions of the respective devices in a fully inserted state. In the fully inserted state, the connecting element returns to its non-prestressed or unprestressed shape. As a result, the connecting element is held on the devices against movement counter to the insertion direction.

[0027] In an advantageous embodiment of the device set, unwanted detachment of the separate connecting element is prevented by the separate connecting element having at least one region that can be actuated by means of a tool to detach the separate connecting element from the devices. The separate connecting element preferably has a substantially W-shaped cross-section, and the separate connecting element is preferably made of spring steel.

[0028] To enable advantageous connection of the device, the connecting regions of the devices can have a defined distance from a side surface, a surface, a bottom surface, a front surface, and / or a rear surface of the device. In this way, even devices with different dimensions can be connected to one another such that, in the connected state, at least one surface of one device is aligned with at least one surface of the other device.

[0029] Preferably, the devices each have at least one first connecting region, wherein in a state in which two devices are connected to one another via an interaction of at least one separate connecting element with the first connecting regions, a surface and / or a lower surface of the devices are arranged in alignment with one another.

[0030] Preferably, the devices have second connecting regions, wherein in a state in which two devices are connected to one another via an interaction of at least one separate connecting element with the second connecting regions, at least one side surface of the devices is arranged in alignment with one another.

[0031] In an advantageous embodiment of a set of devices according to the invention, the devices can have third connecting regions, wherein in a state in which two devices are connected to one another via the interaction of at least one separate connecting element with the third connecting regions, two devices are arranged one behind the other in the longitudinal direction. In this way, in particular two devices with essentially identical cross-sections can be connected to one another and a passage with an increased length can be achieved. A length in the longitudinal direction of the two devices connected to one another in this way can differ from one another. In an advantageous embodiment of the invention, the separate connecting elements are designed to connect the devices via the first connecting regions and the second connecting regions and / or the third connecting regions.This means that a single type of connecting element is sufficient to connect different devices in different areas.

[0032] Further advantages will become apparent from the following description of the figures. The figures illustrate exemplary embodiments of the present invention. The figures, the description, and the claims contain numerous features in combination. Those skilled in the art will also expediently consider the features individually and combine them into useful further combinations.

[0048] Description of embodiments

[0049] Fig. 1 to Fig. 3 show a device 1 for routing one or more lines, pipes, cables, or the like, such as power lines, water lines, gas lines, and the like, through a building part, such as a building wall, a ceiling, and a floor. The device 1 does not require manual opening or closing to route lines or the like through the device 1. Rather, they can be routed through the device 1 without any further measures.

[0050] The device 1 is designed in the present case with two parts 3, 4, each having a substantially U-shaped cross-section, which can be detachably arranged on one another as shown in Fig. 1. The first part 3 and the second part 4 are designed essentially identically to one another. When the parts 3, 4 are connected to one another, the device 1 forms an axial passage channel 6 running in the longitudinal direction L, extending from a first axial end 10 to a second axial end 11 and having, at least in the region of the ends 10, 11, an opening 12, 13 for lines or the like.

[0051] In alternative designs, the device can also be designed in one piece.

[0052] The device 1 has a housing 8 with a housing wall 9, wherein the housing wall forms the axial passage 6 and delimits an interior space 14 of the device 1. The housing 8 in the present case has a substantially rectangular cross-section which, in the assembled state of the device 1, is formed by four walls 16, 17, 18. A first wall 16 lies opposite a second wall 17 and extends in a plane spanned by the longitudinal direction L and a transverse direction Q. The further walls 18, each formed from a wall section of the first part 3 and a wall section of the second part 4, are in turn opposite one another and connect the walls 16 and 17. The further walls 18 extend in a plane spanned by a vertical direction H and the transverse direction Q.

[0053] The longitudinal direction L, the vertical direction H, and the transverse direction Q are each perpendicular to one another. A cross-section of the device 1 is defined by an extension of the device 1 in the vertical direction H and an extension of the device 1 in the transverse direction Q.

[0054] The device 1 has a length L1 in the longitudinal direction L, a width B1 in the transverse direction Q, and a height H1 in the vertical direction H, with each part 3, 4 here having a height corresponding to half the height H1. The ratio of the width B1 to the height H1 is generally freely selectable, with the width B1 in this case being approximately twice the height H1. Accordingly, the device 1 has a rectangular cross-section.

[0055] Since the first part 3 and the second part 4 are essentially comparable to one another, the first part 3 shown in isolation in Fig. 3 will be described below as representative of the second part 4.

[0056] The first part 3 has a first sealing device 22, which here is designed with a plate-shaped foam element 23. The plate-shaped foam element 23 is bent transversely to the longitudinal direction L, so that a first end region 24 of the plate-shaped foam element 23 and a second end region 25 of the plate-shaped foam element 23, opposite the first end region 24, are each arranged in the region of the first wall 16. For this purpose, a holding device designed as a retaining clip 27 or 28 is provided, by means of which the end regions 24 and 25 of the foam element 23 are fixed to the first wall 16. A central region 26 of the foam element 23, arranged between the end regions 24 and 25, extends, in the assembled state of the device 1, from the first wall 16 in the direction of the second wall 17 into the interior space 14.

[0057] In addition to the embodiment shown with a curved plate-shaped foam element, it can also be provided that an already pre-formed foam element is used, which can, for example, have a comparable curved shape to the foam element 23 or can be trapezoidal.

[0058] In the present case, two intumescent elements 37, 38 are connected to the first wall 16 in an extension region 30 of the foam element 23 in the longitudinal direction L between the end regions 24 and 25. These elements are intended to ensure the closure of the interior space 14 in the event of a fire. Alternatively or additionally, further intumescent elements can also be arranged, for example, in the axial end regions 10, 11 of the device 1.

[0059] In the present case, the extension region 30 of the foam element 23 of the first part 3 in the longitudinal direction L corresponds to an extension region 30 of the foam element 23 of the second part 4, so that the common extension region 30 in the longitudinal direction L corresponds to the individual extension regions 30.

[0060] In alternative embodiments, the extension areas of the foam elements of the individual parts can differ from one another, whereby a common extension area is defined by an intersection of the extension areas of the individual foam elements in the longitudinal direction L.

[0061] As can be seen in simplified form in Fig. 1 to Fig. 3, in the region of the axial ends 10, 11 of the device 1, two sealing arrangements 32, 33, 34, 35 are provided, which here each form a sealing plane perpendicular to the longitudinal direction L and which are each designed with a plurality of immediately adjacent, elongated sealing elements 26.

[0062] The sealing elements 26 in this case have a substantially circular cross-section, are flexible and elastic, and have a longitudinal extension that is many times greater than the cross-section of the sealing elements 26. The sealing elements 26 are designed here as elastic lamellae with a plastic fiber made of polypropylene or polyethylene, but in alternative designs they can also be designed as brushes, bristles, strips, bands, hose elements, or the like, and can comprise other materials, such as metal, rubber, biological materials, or the like.

[0063] The sealing elements 26 can also be made of woven fabric, scrim, or paper materials that are flexible, can adhere well to the outer surface of a line or the like guided through the device 1, and, if possible, exert an elastic force on the outer surface to ensure the most tight seal possible in the area around the outer surface of the line. The sealing elements 26 can also comprise an intumescent material and, for example, be coated with an intumescent material or enclose an intumescent material, and in particular, comprise a paper provided with an intumescent material.

[0064] The sealing elements 26 of the first sealing arrangement 32 run perpendicular to the sealing elements 26 of the second sealing arrangement 33. The sealing elements 26 of the third sealing arrangement 34 and the fourth sealing arrangement 35, which are arranged in the region of the second axial end 11 of the device 1, are designed analogously.

[0065] If a line 2, a pipe, a cable or the like is guided through the device 1, the sealing elements 26 of the sealing arrangements 32, 33, 34, 35 are bent in such a way that they rest against a jacket surface 5 of a line 2 guided through the device 1 and thereby seal against the passage of fire gases and smoke and also achieve a certain degree of opacity.

[0066] Furthermore, Fig. 1 to Fig. 3 show a third sealing device 40, a fifth sealing device 42, a seventh sealing device 44, and a ninth sealing device 46, each arranged on the first sealing device 22. Similarly, a fourth sealing device 41, a sixth sealing device 43, an eighth sealing device 45, and a tenth sealing device 47 are arranged on a second sealing device 31 arranged on the second part 4. All sealing devices 40 to 47 are arranged entirely within the common extension area 30.

[0067] In the following, the sealing devices 40, 42, 44, 46 assigned to Part 3 are described as representative of the sealing devices 41, 43, 45, 47 assigned to Part 4.

[0068] In the present case, the sealing devices 40, 42, 44, 46 each have a plurality of sealing elements 48, which can be designed in a manner comparable to the sealing elements 36. The sealing elements 48 are preferably designed as the bristles of a brush, wherein the bristles 48 of the brush have a common longitudinal direction, particularly when the device 1 is unloaded. In the present case, the longitudinal direction of the bristles is not perpendicular to the longitudinal direction L of the device 1, but rather forms an angle 50° with a transverse plane Q extending transversely to the longitudinal direction L, which angle can be, for example, between 0° and 45°, for example approximately 30°.

[0069] The bristles 48 of the brushes are each arranged on a holding element 52, by means of which the brushes are arranged, in particular glued, directly on the first foam element 23. In the present case, the third sealing device 40 and the fifth sealing device 42 are arranged on a side of the central region 26 of the foam element 23 facing the first opening 12 of the device 1, and the seventh sealing device 44 and the ninth sealing device 46 are arranged on a side of the central region 26 of the foam element 23 facing the second opening 13 of the device 1. The length of the sealing elements 48 of the fifth sealing device 42 and the seventh sealing device 44, which are arranged closer to the central region 26 of the foam element 23 than the third sealing device 40 and the ninth sealing device 46, is shorter than the length of the sealing elements 48 of the third sealing device 40 and the ninth sealing device 46.

[0070] The sealing elements 48 of the interacting sealing devices 40 to 47 of the first part 3 and the second part 4 engage with each other in a comb-like manner when the unloaded device 1 is assembled. In alternative embodiments, it can also be provided that the end regions of the sealing elements of the interacting sealing devices are flush with each other when the device 1 is unloaded.

[0071] As can be seen in more detail in Fig. 1, when the device 1 is unloaded, the sealing elements 48 of the sealing devices 40 to 47 interact with each other in a comb-like manner. Furthermore, the central regions 26 of the foam elements 23 abut one another over a certain extent in the longitudinal direction L of the device 1, so that good gas tightness is achieved when the device 1 is unloaded.

[0072] In the loaded state according to Fig. 3, in addition to the sealing arrangements 32 to 35, the area of ​​the foam elements 23 and the area of ​​the sealing devices 40 to 47 also seals off the line 2 guided through the device 1 and gas passage is reliably prevented or gas passage is greatly reduced.

[0073] Fig. 4 shows a set of devices 50, which in this case is designed with four devices 1, 52, 53, 54. The set of devices 50 here also has a frame 56 or wall flange, wherein the devices 1, 52, 53, 54 can be arranged in an internal cross-section 58 or receiving space defined by the frame 56. The internal cross-section 58 of the frame 56 can be flexibly adjusted if necessary, so that, for example, a width 60 of the internal cross-section 58 in the transverse direction Q and / or a height 62 of the internal cross-section 58 in the vertical direction H can be variably adjusted. At least two differently dimensioned devices 1, 52, 53, 54 can be arranged in the internal cross-section 58 of the frame 56.

[0074] In particular, two frames 56 are provided in order to be able to arrange the devices 1, 52, 53, 54 in a simple manner on both sides of a building part, in particular a wall or a ceiling.

[0075] According to the embodiment according to Fig. 4, the set of devices 50 comprises three differently dimensioned devices 1, 52, 53 and 54, wherein the devices 53 and 54 have the same cross-section.

[0076] In this case, the device 52 has a height H2 in the vertical direction that corresponds to the height H1 of the device 1. A width B2 of the device 52 corresponds in this case to half the width B1 of the device 1, whereby the width B2 can in principle assume any value that differs from the width B1 of the device 1. The length L2 of the device 52 is in this case essentially identical to the length L1 of the device 1.

[0077] The devices 53, 54 have a length L3, which also corresponds to the length L1 of the device 1. A width B3 of the devices 53, 54 corresponds in this case to the width B2 of the device 52 and thus corresponds to half the width B1 of the device 1. A height H3 of the devices 53, 54 corresponds in this case to half the height H1 of the device 1 or half the height H2 of the device 52. An arrangement of the two devices 53 and 54 one above the other in the vertical direction H thus has a height H1 or H2 corresponding to that of the devices 1 and 52.

[0078] Particularly preferably, the set of devices comprises devices whose heights H1 substantially correspond to an integer divisor of the height 62 of the inner cross section 58, so that an arrangement of a corresponding number of devices one above the other in the vertical direction H fills the entire height 62 of the inner cross section 58.

[0079] In addition to fixtures with a rectangular cross-section, fixtures with a square cross-section can also be used in the fixture set. Particularly preferred cross-sectional ratios of fixtures in a fixture set are listed in the following tables:

[0080] Table 1

[0081] Table 2

[0082] In principle, the set of devices can also consist of only two devices of different dimensions, each of which differs in its design. Furthermore, the set of devices can also consist of a larger number of devices of different dimensions.

[0083] A number of fixtures with the same dimensions can also be freely selected, so that, for example, all fixtures have different dimensions or dimensions. Any number of fixtures with the same dimensions can be freely selected, so that each fixture can be used once, twice, three times, or more times.

[0084] In addition to the arrangement of various devices 1, 52, 53, 54 next to one another in the transverse direction Q and / or vertical direction H, it can also be provided that various devices 1, 52, 53, 54 are arranged one behind the other in the longitudinal direction L. In this case, devices with a substantially identical cross-section are used. In Fig. 6, for example, the arrangement of two devices 1 and 55 one behind the other in the longitudinal direction L is shown, with device 55 essentially corresponding to device 1.

[0085] Alternatively, it can also be provided that the device 55 essentially corresponds to the structure of the device 1, but has a length L4 that differs from the length L1. The length L4 can, for example, correspond to half the length L1. In principle, the length L4 of the device 55 can assume any value relative to the length L1 of the device 1.

[0086] The devices 1, 52, 53, 54, 55 each have two transversely facing side surfaces 78 and 79, each of which borders on a surface 80 and a bottom surface 81.

[0087] In the present case, each device 1, 52, 53, 54, 55 has first connecting regions 72, second connecting regions 74, and third connecting regions 76, wherein two devices 1, 52, 53, 54, 55 can be detachably connected to one another via connecting elements 70 described in more detail later. The first connecting regions 72 are provided for connecting two devices 1, 52, 53, 54, 55 in the transverse direction Q through interaction by means of one or more connecting elements 70. Via the second connecting regions 74, two devices 1, 52, 53, 54, 55 can be connected to one another in the vertical direction H by means of one or more connecting elements 70. Finally, two devices 1, 52, 53, 54, 55 can be releasably connected to one another in the longitudinal direction L via an interaction of at least one connecting element with the third connecting regions 76.

[0088] The devices 1, 52, 53, 54, 55 can each have one or more, in particular two or preferably four, connecting regions 72, 74, 76, via which two devices 1, 52, 53, 54, 55 can be detachably connected to one another in the transverse direction Q, in the vertical direction H or in the longitudinal direction L by means of one or more connecting elements 70.

[0089] In the present case, it is provided that similar devices 1, 52, 53, 54, 55 and also differently dimensioned devices 1, 52, 53, 54, 55 can be detachably connected to one another in the transverse direction Q, in the vertical direction H and in the longitudinal direction L by means of identically designed connecting elements 70, wherein devices 1, 52, 53, 54, 55 to be connected to one another in the longitudinal direction L in particular have a substantially identical cross-section.

[0090] In order to connect two devices 1, 52, 53, 54, 55 in the transverse direction Q, the devices 1, 52, 53, 54, 55 each have, in the present case, two first connecting regions 72 in a transition region of a side surface 78 or 79 to the surface 80 and to the lower surface 81, so that each device has, in the present case, eight first connecting regions 72. A distance 73 from the first connecting regions 72 assigned to the first axial end 10 from the first axial end 10 and a distance 73 from the first connecting regions 72 assigned to the second axial end 11 from the second axial end 11 is, in the present case, essentially identical for all first connecting regions 72 and, in the present case, also essentially identical for all devices 1, 52, 53, 54, 55.

[0091] As can be seen in more detail in Fig. 4, for example, device 1 and device 52 can be detachably connected to one another via four connecting elements 70, each of which interacts with corresponding first connecting regions 72. Two connecting elements 70 interact with devices 1 and 52 in the region of surfaces 80, and two connecting elements 70 interact with devices 1 and 52 in the region of lower surfaces 81. When connected to one another, surfaces 80 and lower surfaces 81 of devices 1 and 52 are arranged substantially flush with one another.

[0092] In order to connect two devices 1, 52, 53, 54, 55 in the vertical direction H, the devices 1, 52, 53, 54, 55 each have, in the present case, two second connecting regions 74 in a transition region of a side surface 78 or 79 to the surface 80 and to the lower surface 81, so that each device 1, 52, 53, 54, 55 has, in the present case, eight first connecting regions 74. A distance 75 from the first axial end 10 of the second connecting regions 74 assigned to the first axial end 10 and a distance 75 from the second connecting regions 74 assigned to the second axial end 11 and the second axial end 11 is, in the present case, essentially identical for all second connecting regions 74 and, in the present case, also essentially identical for all devices 1, 52, 53, 54, 55.

[0093] The first connecting regions 72 and the second connecting regions 74 are each formed by material recesses in the housing wall 9 of the devices 1, 52, 53, 54, 55, wherein the first connecting regions 72 and the second connecting regions 74 are formed by identical material recesses and are thus arranged in identical regions of the devices 1, 52, 53, 54, 55.

[0094] As can be seen in more detail in Fig. 4, for example, the device 53 and the device 54 can be detachably connected to one another via four connecting elements 70, each of which interacts with corresponding second connecting regions 74. Two connecting elements 70 interact with the devices 53 and 54 in the region of each side surface 78 and 79. In the connected state, the side surfaces 78 and 79 of the devices 53 and 54 are arranged substantially flush with one another.

[0095] In order to connect two devices 1, 52, 53, 54, 55 to one another in the longitudinal direction L, as can be seen, for example, in Fig. 6, eight third connecting regions 76 are provided in the region of each axial end 10 or 11. Two third connecting regions 76 are arranged in a transition region between a side surface 78 or 79, the surface 80 or the lower surface 81, and a front surface 82 or a rear surface 83 of the device 1, 52, 53, 54, 55. Two devices 1, 52, 53, 54, 55 connected to one another in the longitudinal direction L have, in particular, a substantially identical cross-section, wherein, in particular, all third connecting regions 76 are provided at identical positions.

[0096] The third connecting regions 76 are also comparable to the first connecting regions 72 and the second connecting regions 74 and are each formed by material recesses in the housing wall 9 of the devices 1, 52, 53, 54, 55.

[0097] The connecting element 70 shown in isolation in Fig. 8 and Fig. 9 has a W-shaped cross-section. Each lateral leg 84 or 85 is resiliently connected to a central, U-shaped cross-sectional area 86, which forms a receiving area 89. The legs 84, 85 each form an angle 68, for example, approximately 20°, with a central axis 67 of the connecting element 70. The central U-shaped area 86 forms a recess 87 with a width 88.

[0098] Fig. 10 and Fig. 11 show, in a highly simplified example, a first connecting region 72 of device 1 and a first connecting region 72 of device 52, via which devices 1 and 52 can be detachably connected to one another in the transverse direction Q. It can be seen that, with appropriate alignment of devices 1 and 52 to one another, devices 1 and 52 form an insertion opening 90 for connecting element 70, through which connecting element 70, starting from the intermediate state in Fig. 8, can be inserted in an insertion direction 92 completely in the longitudinal direction L into the region of devices 1 and 52. In the state connecting devices 1 and 52 to one another according to Fig. 11, the U-shaped region 86 of connecting element 70 comprises a first wall region 94 of device 1 and a first wall region 95 of device 52.The legs 84 and 85 are pre-tensioned during the insertion process and relax during the fully inserted process such that the legs 84 and 85 prevent movement of the connecting element 70 counter to the insertion direction 92 by means of a corresponding undercut in the walls of the devices 1 and 52. Thus, when connected to the devices 1 and 52, the connecting element 70 does not protrude beyond an outer surface of the devices 1 and 52.

[0099] In the state shown in Fig. 11, the connecting element 70 is shown in a locked state in which the devices 1 and 52 are connected to each other by the connecting element 70 and an unintentional release of the connecting element 70 is reliably prevented.

[0100] The connecting element 70 has a recess 69 in the region of each leg 84 and 85, via which the connecting element 70 can be transferred, for example by engagement of a tool, from the locked state according to Fig. 11 into a state in which the connecting element 70 can be released from the devices 1 and 52 opposite to the insertion direction 90.

[0101] The devices 1 and 52 can be connected to further devices 1, 52, 53, 54, 55 via connecting elements 70 in the vertical direction H via the second wall regions 97 and 98 shown in Fig. 10 and Fig. 11, wherein a connecting element 70 for this purpose is in engagement with the respective devices 1, 52, 53, 54, 55 in the insertion direction 100.
