Furthermore, the conventional channel arrangement is only accessible from one side. There is therefore a need for a kit for a channel arrangement and for a channel arrangement which is provided by such a kit, the

Channel arrangement is inexpensive to manufacture and can be flexibly adapted to the requirements of a laboratory. According to a first aspect, embodiments provide a kit for assembling a channel arrangement of a laboratory device, in particular for assembling one Channel arrangement for supply and / or disposal lines of a laboratory facility ready. The kit has: a multiplicity of wall elements which can be detachably connected to one another to form a channel which, in at least one cross section perpendicular to a channel axis of the channel, has a peripheral opening. The wall elements each form a peripheral section of an outer contour of the cross section. The kit also has a stiffening element, which can be arranged so that the

Stiffening element connects two neighboring elements of the plurality of wall elements, which, viewed in the circumferential direction, are each arranged adjacent to the circumferential opening. The kit also has a cover element which, if the arrangement of the neighboring elements and the stiffening element is unchanged, can be brought into engagement with the neighboring elements in a separable manner so that the covering element connects the two neighboring elements to one another and is arranged on the outside relative to at least part of the stiffening element. When the cover element is separated, the stiffening element stiffens the opening on the circumference to prevent the channel from widening in the circumferential direction.

Embodiment.

FIG. 1A shows a channel arrangement 1 for a laboratory, for example for a chemical, analytical and / or physical laboratory. The channel arrangement 1 provides a channel 2 which serves as a media channel, ie the channel 2 is used to accommodate supply and / or disposal lines for laboratory media. Laboratory media can be, for example: Liquids such as chemicals, water, waste water, gases, such as nitrogen or oxygen, compressed air, exhaust air, vacuum, data, voltage and / or current.

The channel arrangement 1 is composed of elements of a kit, which in the exemplary embodiment shown can be connected to one another without screws by the

Elements of the kit are connected using snap-in connections. However, other screwless connections are also conceivable. The snap connections enable quick assembly, disassembly and maintenance. However, it is also conceivable that the

Channel arrangement 1 has one or more screw connections.

The channel 2 is closed in the cross section shown in the circumferential direction. It is conceivable that the channel 2 has one or more openings outside the cross section shown. An outer contour of the cross section is rectangular. The rectangular outer contour is rounded at the corners. Alternatively, the corners can have a phase or be pointed. Each side of the rectangular outer contour is covered by one

Wall element of the kit is formed. Each of these wall elements is seen in

Circumferential direction of the channel, at opposite end sections each with an adjacent wall element in engagement, that is, in adjacent contact.

Seen in cross section perpendicular to the channel axis, a width b and / or a height h of the channel can have a value which is equal to or greater than 75 millimeters or equal to or greater than 100 millimeters. The width b and / or the height h can be equal to or less than 200 millimeters or equal to or less than 150 millimeters.

A stiffening element 3 is arranged in an interior of the channel 2. The

Stiffening element 3, as seen in the circumferential direction of the channel 2, engages with an adjacent element 4, 5 of the kit at opposite end sections. Furthermore, the channel arrangement 1 has a cover element 6, which is relative to at least one Part of the stiffening element 3 is arranged on the outside. An inner peripheral surface of the cover element 6 faces the stiffening element 3. The

Stiffening element 3 can, seen along the channel axis, offset relative to

Cover element 6 may be arranged. This makes it possible for the cover element 6 on the outside to only a part (in particular an axial section) of the

Stiffening element 3 is arranged.

The cover element 6, as seen in the circumferential direction of the channel 2, is also on

opposite end portions each with one of the neighboring elements 4, 5 in engagement. In other words, the stiffening element 3 and the cover element 6, viewed in the circumferential direction, jointly have the adjacent elements 4 and 5 as adjacent wall elements, with which the stiffening element 3 and the cover element 6 are respectively engaged.

The cover element 6 is designed so that this with a fixed arrangement of

Neighboring elements 4, 5 and the stiffening element 3 can be brought into engagement with the two neighboring elements 4 and 5 in a separable manner. Therefore, the cover element 6 acts as a releasably attachable cover for the channel 2. By separating the cover element 6, there is a peripheral opening in a cross section perpendicular to the channel axis, which does not have the stiffening element. This circumferential opening is identified in FIG. 1B with the reference symbol 72. FIG. 1B shows channel 2 with the cover element separated. The channel 2 is accessible from the outside through the circumferential opening 72, for example to carry out maintenance work on media lines inside the channel 2.

The engagement between the stiffening element 3 and the neighboring elements 4, 5 is designed such that when the cover element 6 is separated, the circumferential opening 72 is stiffened against widening of the channel 2 in the circumferential direction. In other words, an expansion of the peripheral opening 72, which is caused by the separation of the Cover element 6 results prevented. This is achieved by positive connections between the stiffening element 3 and the neighboring elements 4, 5. Therefore, the stiffening element 3 enables the construction of a channel 2, the outer contour of which, viewed in the circumferential direction, is composed of four or more elements.

In particular, the stiffening element 3 makes it possible to provide a channel without using a one-piece U-profile, by means of which three sides of the outer contour are held in a stable position relative to one another when the channel is opened on the circumference.

Avoiding a U-profile leads to lower costs of the channel arrangement, since the production of a U-profile is associated with comparatively high costs. In addition, the production of openings in the U-profile is more expensive.

FIG. 1B shows a further stiffening element 7, which, relative to the stiffening element 3, is spaced axially relative to the channel axis of the channel 2. Each of the stiffening elements 3 and 7 each has one or more fixing sections 8. With the help of the fixing sections 8, components in the interior of the channel 2, such as supply and / or disposal lines, can be fixed relative to the channel arrangement 1.

In other words, the stiffening elements 3 and 7 function not only to stiffen the channel arrangement 1, but also to fix components within the channel 2.

In the exemplary embodiment shown, the axial positions of the stiffening elements 3 and 7 can be selected continuously. This enables the axial position of the

Stiffening elements 3 and 7 can be flexibly adapted to the requirements of the respective laboratory. For example, the axial spacing of the stiffening elements can be chosen to be large in axial regions of the channel 2, in which frequent access must be carried out due to maintenance work. Furthermore, stiffening elements with a small axial distance can be arranged in areas in which supply and / or disposal lines in the interior of the channel 2 have to be fixed as rigidly as possible. The stepless axial arrangement of the stiffening elements 3 and 7 is made possible in particular in an efficient manner that both the stiffening elements 3 and 7 and the neighboring elements 4 and 5 are each designed as a profile, the profile axis of which extends parallel to the channel axis. However, embodiments are also conceivable in which the axial position of the stiffening elements 3 and 7 can only be changed in predefined steps.

The duct arrangement 1 shown in FIG. 1A has a wall element 9 which is arranged opposite the cover element 6 and which can also be designed as a cover, i.e. which is selectively engageable with the wall elements 4 and 5 so that the wall element 9 connects the neighboring elements 4 and 5. The neighboring element 9 therefore functions like the cover element 6 as a separable cover (i.e. as a second cover element). To stiffen channel 1 when the

Wall element 9, the channel 2 has a stiffening element 10 which - like the stiffening element 3 - engages with the neighboring elements 4 and 5, so that the stiffening element 10 connects the neighboring elements 4 and 5. The stiffening element 10 serves to stiffen the channel against widening of a circumferential opening in the circumferential direction, the circumferential opening resulting from a separation of the wall element 9 (i.e. the second cover element) from the rest of the duct 2.

It has been shown that this enables the channel arrangement 1 to be used much more flexibly within a laboratory device, since this means the channel 2 of two

opposite sides is accessible. For example, channel 2 can thereby be arranged in the middle of a double work station. This is a significant advantage over conventional channel arrangements, which have a U-profile and a cover, which serves to cover the U-profile. Such a conventional channel arrangement is only accessible from one side and is therefore comparatively inflexible in use. FIG. 2 shows an individual perspective view of the stiffening element 3.

Seen along the channel axis of the channel 2 is an axial extent a of

Stiffening element 3 is less than an axial extension of the cover element 6.

In particular, the axial extent a of the stiffening element is less than half or less than a third, or less than a quarter of the axial extent of the cover element 6. This makes it possible that when the cover element 6 is separated from the rest of the channel 2, the peripheral opening 72 ( shown in Figure 1B) of the channel 2, which allows access to an interior of the channel 2, for example, to carry out maintenance work on the media lines, which are located inside the channel.

As shown in FIG. 2, the stiffening element 3 has two engagement sections 11 and 12, which, viewed in the circumferential direction, relative to the channel axis

opposite end portions of the stiffening element 3 are arranged. The engaging sections 11 and 12 are connected to one another via a connecting section 14, which is at least partially flat, in particular flat. The flat connection section 14 has an inner flat side, which the

Channel axis is facing and facing away from the cover member 6. Furthermore, the flat connecting section 14 has an outer flat side which faces away from the channel axis and faces the cover element 6. The fixing sections 8 protrude outward and in a direction away from the connecting section 14

Cover element 6.

The engagement sections 11 and 12 are each designed such that an engagement of the engagement sections 11 and 12 with corresponding engagement sections, which are provided in the neighboring elements 4 and 5, creates a connection between the

Neighboring elements 4 and 5 are provided, which, seen in a cross section perpendicular to the channel axis, leads to a fixed orientation between the neighboring elements 4 and 5. This causes the stiffening element 3 when separated, as in

arranged cover element 6 stiffening the outer contour of the channel 2.

The engagement section 11 has a projection 15 which, as shown in FIGS. 1A and 1B, projects into a corresponding recess 73 in the wall element 4. The projection 15 and the recess 73 are each designed as a profile section. The projection 15 has a first contact surface 23 with which the stiffening element 3 is in contact with the neighboring element 4. Furthermore, the engagement section 11 has a second contact surface 24, with which the engagement section 11 is also in contact with the neighboring element 4. The contact surfaces 23 and 24 each run parallel to

Channel axis and are inclined relative to each other. An angle of inclination a between the

Contact surfaces 23 and 24, measured in a plane perpendicular to the channel axis, is greater than 5 degrees or greater than 10 degrees or greater than 20 degrees. The angle of inclination can be less than 90 degrees or less than 60 degrees. The angle of inclination can be designed in such a way that it leads to an improvement in the fit between the stiffening element 3 and the neighboring element 4.

Through the contact surfaces 23 and 24, the stiffening element 3, seen in cross section perpendicular to the channel axis, can be connected in an orientation-fixed manner to the adjacent wall element 4, a stop being formed by the inclination between the contact surfaces 23 when the projection 15 is inserted into the corresponding recess 73 becomes.

The projection 15 extends in a direction away from the cover element 6. In particular, the projection 15 extends perpendicularly or substantially perpendicularly to a plane of the peripheral opening. This facilitates the arrangement of the stiffening element 3 from the outside. The engagement section 11 also has a latching section which is designed to engage with a corresponding counter-latching section of the neighboring element 4. The latching section, viewed in the circumferential direction, is arranged closer to the circumferential direction center M of the stiffening element 3 than the projection 15. The latching section has a latching arm 16 which projects in a direction away from the cover element 6 and which has a latching nose 17 at a free end section having. However, it is also conceivable for the counter-latching section of the neighboring element 4 to have a latching arm with a latching lug which is designed for latching engagement with the latching section of the engagement section 11.

It has been shown that this design of the engaging section 11 enables simple mounting of the stiffening element 3 in the channel arrangement 1 with the cover element 6 separated. In particular, the stiffening element 3 can thereby be brought into engagement with the neighboring element 4 by movement along a direction substantially perpendicular to the plane of the peripheral opening.

In the exemplary embodiment shown, the engagement sections 11 and 12 are designed symmetrically with respect to a central plane which runs through the circumferential direction center M of the stiffening element 3. However, they are also asymmetrical to each other

Engagement sections 11 and 12 conceivable.

FIG. 3 shows a single view of one of the neighboring elements 4, 5, which are of identical design in the exemplary embodiment shown. However, it is conceivable that the

Neighboring elements 4, 5 are designed differently. The neighboring element 4, 5 has two engagement sections 34, 35 which, viewed in the circumferential direction, are arranged on opposite end sections of the neighboring element 4, 5. The engagement sections 34 and 35 are each for engagement with a corresponding engagement section of the

Stiffening element 3 and for engagement with a corresponding one

Engagement section of the cover member 6 is formed. Each of the engaging portions 34 and 35 has a recess 36, 37. The recesses 36, 37 are each formed as a groove, which extend along the channel axis and which each

are formed corresponding to the projection 15 of the engagement portion 11 of the stiffening element 3.

As is also shown in FIG. 3, the neighboring elements 4, 5 have two grooves 40 and 41 on an outer side, which extend along the channel axis. For each of these grooves 40, 41, a depth direction of the respective groove runs essentially along the circumferential direction (i.e. along the side of the square outer contour, which is represented by the neighboring element 4, 5). The grooves 40, 41 are arranged so that together they form a T-groove. As will be described below with reference to Figures 10A and 10B, the grooves 40 and 41 allow the attachment of

Extension components of the channel arrangement 1. As a result, the channel 2 can simultaneously serve as a carrier for these extension components. In the same way, two grooves 42, 43 are likewise arranged in an inner side of the adjacent elements 4, 5, which also extend along the channel axis and whose depth direction likewise runs essentially along the circumferential direction. The grooves 42, 43 also form a T-groove and allow components to be fastened inside the channel 2.

Figure 4 is an individual perspective view of the cover element 6. Das

Cover element 6, viewed in the circumferential direction, has an engaging portion 44, 45 on opposite end portions for engaging with corresponding portions 38, 39 (shown in FIG. 3) of engaging portions 4 and 35 of FIG

Neighboring elements 4, 5. The engaging section 44 is designed to engage with one of the neighboring elements 4, 5. To effect the locking engagement, the

Engagement section 44 on a locking arm 55. The engagement section 45 arranged on the opposite end section is designed for non-latching engagement with one of the neighboring elements 4, 5. To separate the cover element 6 from the rest of the channel, the locking engagement, which is brought about with the aid of the engagement section 44, is released, the non-latching engagement, which is brought about with the aid of the engagement section 45, performs a hinge function. As shown in FIG. 3, the subsections 38 and 39 of the engagement sections 34 and 35 are shown in FIG

Neighboring elements 4, 5 are formed identically at both opposite end sections. Each of these sections 38 and 39 is therefore designed both for latching engagement and for non-latching engagement. FIG. 5 shows a channel arrangement 1 a according to a second exemplary embodiment. The channel arrangement 1 a of the second exemplary embodiment has components which are analogous to components of the first exemplary embodiment illustrated in the preceding figures, but are not necessarily identical. To simplify the illustration, the components of the second exemplary embodiment are therefore provided with similar reference symbols, which, however, have the accompanying symbol "a".

As with the channel arrangement 1 (shown in Figures 1A and 1B) of the first

Embodiment, the channel arrangement la of the second embodiment can also be assembled using a kit. The channel arrangement la has the cover elements 6a and 9a, which are identical to the cover elements 6 and 9 of the first

Embodiment are formed. The channel arrangement la has the

Stiffening elements 3a and 10a and the wall elements 4a and 5b, which

are different from the stiffening elements and wall elements of the channel arrangement of the first exemplary embodiment.

FIG. 6 shows an individual illustration of the stiffening element 3 a. Of the

Engagement section 11 A has a recess 30a for receiving one

corresponding projection of the neighboring element 4a. The recess 30a is on one End portion of a leg 31a arranged, which protrudes relative to the connecting portion 14a, in a direction away from the cover member 6a. Contact surfaces 32a and 34a are formed on opposite inner surfaces of the recess 30a, which engage with corresponding corresponding contact surfaces of the neighboring element 4a and which, seen in a cross section perpendicular to the channel axis, form an orientation-fixed connection between the neighboring element 4a and the

Stiffening element 3 a effect.

The opposite engagement portion 12a is mirror-symmetrical relative to a plane through the circumferential direction center M of the stiffening element 3a. However, it is also conceivable that the engagement sections 11a, 12a deviate from mirror symmetry.

The recess 30a opens in a direction towards the cover element 6a. A

The depth direction of the recess 30a extends perpendicularly or substantially perpendicularly to a plane of the peripheral opening. As a result, the

Recess 30a with a corresponding projection of the neighboring element 4a, the stiffening element 3a with a separated cover element 6a (shown in FIG. 5) are prevented from being separated from the rest of the channel arrangement la through the circumferential through opening. This makes it possible to fasten the channel arrangement 1 a to a wall using a plurality of stiffening elements when the cover element 6 a is separated, the stiffening elements each being fastened to the wall using fastening means (such as screws).

FIG. 7 shows a channel arrangement 1b according to a third exemplary embodiment. The channel arrangement 1b of the third exemplary embodiment has components which are components of the first and second shown in the preceding figures

Exemplary embodiments are analogous, but are not necessarily identical. To simplify the In the illustration, the components of the second exemplary embodiment are therefore provided with similar reference numerals, which, however, have the accompanying symbol "b".

The components of the channel arrangement 1b are combined to form a double channel which, in addition to a first channel 2b, has a second channel 49b running parallel thereto. The kit provides instructions for the formation of the double channel

Partition wall element 50b, which is arranged between an interior of the channel 2 and an interior of the channel 49b.

Stiffening elements 10b, 51b are arranged in each of the channels 2b and 49b on the inside of the channel of the intermediate wall element 50b. Furthermore, stiffening elements 3b and 52b are arranged on the inside of the channel to cover elements 6b and 55b. The

Stiffening elements 3b, 10b, 51b and 52b are each identical to the stiffening element 3, which was described with reference to FIG. 2. However, it is also conceivable that the stiffening elements 3b, 10b, 51b and 52b correspond to the

Stiffening element 3 a of the second embodiment are formed.

The cover elements 55b and 6b are identical to the cover element 6 of the first

Embodiment formed, which was described with reference to Figure 4. The neighboring elements 4b and 5b, which are identical to the neighboring elements 4 and 5 of the first, are arranged in the circumferential direction adjacent to the cover elements 6b, to the intermediate wall element 50b, and to the stiffening elements 3b and 10b

Embodiment are formed, which was described with reference to Figure 3.

In the circumferential direction adjacent to the cover element 55b, the intermediate wall element 50b, and to the stiffening elements 51b and 52b, the neighboring elements 53b and 54b are arranged, which are also identical to the neighboring elements 4 and 5 of the first

Embodiment are formed. By using the cover elements 6b and 55b as well as the stiffening elements 3b and 52b arranged on the inside of the channel to these cover elements, the

Channel arrangement 1b can be opened from both sides in order to gain access to both the interior of the first channel 2b and the interior of the second channel 49b. Like in

As will be explained in more detail below, the intermediate wall element 50b functions as an optionally separable cover element both for the first channel 2b and for the second channel 49b. The stiffening elements 10b and 51b then act to reinforce the circumference against expansion of the respective channel in the circumferential direction when the cover element 50b is separated from the respective channel.

FIG. 8 shows a schematic and perspective individual representation of the intermediate wall element 50b. The intermediate wall element 50b, viewed in the circumferential direction of one of the channels 2b or 49b, has one at opposite end sections

Engagement section 51b, 52b. Each of the engaging portions 51b and 52b has two portions (i.e., portions 53b, 54b, 55b and 56b).

The engagement section 51b has the section 53b, which is designed for locking engagement with a neighboring element of the second channel 49b (shown in FIG. 7), and the section 54b, which is designed for non-latching engagement with a neighboring element of the first channel 2b. The engagement section 52b has the section 56b, which is designed for non-latching engagement with a neighboring element of the second channel 49b, and the section 55b, which is designed for latching engagement with a neighboring element of the first channel 2b.

The sections 53b, 54b, 55b and 56b are arranged in such a way that the intermediate wall element 50b provides a section with a non-latching engagement and a section with a latching engagement for each of the channels 2b, 49b. The intermediate wall element 50b has a central axis A (shown in Figures 7 and 8), which by a

Circumferential direction center of the intermediate wall element 50b extends, and around which the sections 53b, 54b, 55b and 56b are formed axisymmetrically. However, arrangements of the sections 53b, 54b, 55b and 56b are also conceivable, which are not axially symmetrical about the central axis M.

The sections 53b, 54b, 55b and 56b make it possible, for example, to gain access to the second channel 49b of the double channel shown in FIG. 7 conveniently in the middle by releasing the locking engagement of the section 53b, for example by an attack with a tool between the wall elements 4 and 53. The intermediate wall element 50b remains fixed relative to the second channel 2b. Alternatively, for an access to the first channel 2b on the opposite side, the latching engagement of the section 55b can be released, the intermediate wall element 50b remaining fixed relative to the second channel 49b.

FIG. 9 shows the channel arrangement 1 of the first exemplary embodiment (likewise shown in FIGS. 1A and 1B) in a state in which the engagement section 44, the

Cover element 6, which is designed to engage with the neighboring element 4, has been released. This makes visible the sealing element 58, which, viewed relative to the channel axis, is arranged between an outer peripheral surface of the stiffening element 3 and an inner peripheral surface of the cover element 6. Furthermore, the sealing element 59 is visible, which is arranged between an outer circumferential surface of the stiffening element 7 and an inner circumferential surface of the cover element 6. Each of the sealing elements 58 and 59 extends, in relation to the channel axis, in the circumferential direction, specifically from a center of the circumferential direction of the corresponding stiffening element 3, 7 in both circumferential directions. The sealing elements 58 and 59 are designed to be elastic and flat. In the configuration of the channel construction arrangement 1, as shown in FIG. 9, the stiffening elements 3 and 57 project in the axial direction beyond both axial ends of the cover element 6, on which the opposite axial boundary edges 62, 63 of the cover element 6 are arranged. Therefore, seen in the axial direction, the cover element 6 overlaps only part of the stiffening element 3 and only part of the stiffening element 57. The stiffening elements 3 and 57 therefore axially partially overlap with the

Cover element 6, as well as with axially adjacent cover elements, which are not shown in FIG. 9. The sealing elements 58 and 59 therefore serve to seal transitions between the cover element 6 and the cover elements adjacent in the axial direction.

As can be seen in FIG. 9, the channel arrangement 1 also has a sealing element 60 which is arranged between the covering element 6 and the neighboring element 4, the covering element 6 and the neighboring element 4 each having sealing surfaces for the sealing element 60. In particular, a groove 64 is provided in the neighboring element 4, in which the sealing element 60 is at least partially received. In the same way is a

Sealing element 61 is provided between the cover element 6 and the neighboring element 5, the sealing element 61 being at least partially received in a groove 65 of the neighboring element 5. The sealing elements 60 and 61 extend parallel to the channel axis. The sealing elements 58 and 59 are each sealingly engaged with both sealing elements 60 and 61. Therefore, the sealing elements 58, 59, 60 and 61 can provide a circumferential seal for the cover element 6 for everyone in the axial direction and in

Circumferential direction of adjacent wall elements.

FIG. 10A shows a schematic perspective view of the channel arrangement 1b shown in FIG. 7 according to a third exemplary embodiment, wherein

Lighting components 66b and 67b on the neighboring elements 4b and 5b of the Channel assembly lb are attached. The lighting components 66b and 67b are connected to the neighboring elements 4b and 5b by means of the neighboring elements 4b and 5b

provided grooves 40b attached, the depth direction of which extends in the circumferential direction. The grooves 40b in the neighboring elements 4b and 4b were explained in more detail above with reference to FIG. 3. In the arrangement shown in Figure 10A, the

Direction of depth of the groove 40 is aligned vertically, so that the lighting components 66b and 67b can be hung on the grooves 40 with the aid of engagement sections 68b which correspond to the grooves and which is designed as a hook. The engaging portion 68b is held in the groove 40b by gravity. This fastening of the lighting components 66b and 67b to the neighboring elements 4b and 5b of the channel arrangement 1b enables the lighting components 66b and 67b to be easily separated from the rest of the channel arrangement 1b in order, for example, to gain access to the interior of the channels 2b and 49b.

The duct arrangement 1b shown in FIG. 10A can be attached to a support structure, such as

For example, a part of a building, such as a ceiling of a laboratory, in particular hanging, to be attached, on the one hand to guide laboratory media in the channels 2b and 49b, and on the other hand to provide efficient lighting for the laboratory. It is conceivable that the support structure is formed by a wall. The attachment can take place, for example, via one or more fastening elements, not shown, with the aid of which the

Neighboring elements 53b and / or 54b are connected to the support structure. An alternative embodiment for fastening to a support structure is the fourth exemplary embodiment explained below, in which the neighboring elements are designed differently.

The modular construction of the cable arrangement 1b from the described components makes it possible to selectively expand the first and second channels 2b and 49b with a third or fourth channel in a vertical direction upwards or downwards, or only a single channel, such as, for example Channel 2b. Furthermore, the Channels 2b and 49b are individually accessible, for example, by opening the cover element 6b, the resulting opening on the circumference using the

Stiffening element 3b is stabilized. After the lighting components 66b and 67b have been released from engagement with the neighboring elements 4b and 5b, the

Double channel (as has been described with reference to FIGS. 7 and 8) can be opened at the location of the intermediate wall element 50b, for example in order to gain access to the upper channel 49b.

This provides a modular channel system that can be used for different

Laboratory requirements can be adapted and which allows easy assembly and maintenance. In addition, the channels serve as supports for laboratory lighting. Like in

As described below, other adaptations are possible as an alternative to lighting.

FIG. 10B shows the channel arrangement 1b, in which the double channel is one

Extension duct component 69b has been expanded, which together with the neighboring elements 5b and 54b forms a third duct 70b. The configuration of the channel arrangement 1b shown in FIG. 10B can also advantageously be attached to a support structure, such as on the ceiling of a laboratory, in particular hanging.

The third channel 70b is designed in such a way that it can also serve to receive supply and / or disposal lines. The add-on duct component 69b likewise has an engagement section 68b which is designed in the form of a hook and engages in the groove 40b of the adjacent element 5b. As a result, the add-on duct component 69b can easily be separated from the neighboring element 5b, for example in order to obtain access to the second duct 49b in the region of the intermediate element 50b. The add-on duct component 69b has a wall section 71b, which is arranged at an angle to a straight line to the neighboring element 5b. One or more openings can be arranged in the wall section 71b (not shown in FIG. 10B), through which withdrawal and / or receiving fittings extend, which serve for removing and / or receiving media, their supply and / or disposal lines through the Channels 2b and 49b are performed.

The add-on duct component 69B also has a second engagement section 146b in order to connect the add-on duct component 69b to a support structure, which is provided, for example, by a ceiling or by a wall. The connection can be made, for example, with the aid of fastening elements, as described below for the fourth exemplary embodiment with reference to FIG. 11A.

The add-on duct component 69b furthermore has a groove or T-groove 115b on a rectilinear section 116b of the outer contour of the duct 70b, with the

Section 116b extends parallel to the rectilinear section of the outer contour of the channel 2b, which is formed by the neighboring element 5b. The groove or T-groove is arranged on an outside relative to the channel 70b. With the aid of the groove or T-groove 115b, further components, such as, for example, can be attached to the mounting channel component 69b

Illumination component 66b (shown in Figure 10A) can be attached.

FIG. 11A shows a channel arrangement 1c according to a fourth exemplary embodiment. The channel arrangement 1c of the fourth exemplary embodiment has components which are components of the first to third shown in the preceding figures

Exemplary embodiments are analogous, but are not necessarily identical. To simplify the illustration, the components of the fourth exemplary embodiment are therefore provided with similar reference numerals, which, however, have the accompanying character "c". The channel arrangement 1c of the fourth exemplary embodiment has two neighboring elements 74c and 75c, which are each arranged on the circumferential side adjacent to the covering element 6c, so that the covering element 6c connects the neighboring elements 74c and 75c to one another in the circumferential direction. The cover element 6c is designed as a cover for the channel arrangement 1c, so that, with the arrangement of the adjacent elements 74c and 75c and the stiffening element 3c unchanged, the cover element 6c can be optionally separated with the

Neighboring elements 74c and 75c can be brought into engagement. The stiffening element 3c connects the two neighboring elements 74c and 75c to one another, the cover element 6c

is arranged on the outside relative to at least part of the stiffening element 3 c.

The neighboring elements 74c and 75c are, seen relative to the channel axis of FIG

Channel arrangement lc arranged opposite to each other and form parallel sections of the outer cross section of the channel arrangement lc arranged parallel to each other. The neighboring elements 74c and 75c each have an engagement section 112c and 113c, respectively, for engagement with corresponding engagement sections of the cover element 6c and the stiffening element 3c. Furthermore, each of the wall elements 74c and 75c has a further engagement section 76c or 77c at an end section opposite the engagement section 112c or 113c, viewed in the circumferential direction. With the aid of the further engagement sections 76c and 77c, the adjacent elements 74c and 75c can each be connected to at least one fastening element 78c or 79c for fastening the channel arrangement 1c to a support structure. The supporting structure can be provided, for example, by a building element, such as a wall or a ceiling. In the exemplary embodiment of the channel arrangement 1c shown, the fastening elements 78c and 79c each have a first fastening section 80c and 81c, which is designed as a thread. The fastening elements 78c and 79c can be connected to the supporting structure with the aid of the threads. Each of the fastening sections 80c and 81c each has a longitudinal axis which extends perpendicular to the straight section of the outer cross section which is formed by the cover element 6c. The fastening elements 78c and 79c each have a second fastening section 84c or 85c, by means of which the respective fastening element 78c or 79c can be connected to the engagement section 76c or 77c of the neighboring element 74c or 75c. The second fastening sections 84c and 85c are each designed as a clamping device for clamping fastening to the corresponding neighboring element 74c or 75c. For this purpose, each of the second fastening sections 84c or 85c each has a nut 82c or 83c, which is in engagement with the thread 80c or 81c of the respective fastening element 78c or 79c. With the help of the nut 82c or 83c, a clamping force can be generated for the clamping fastening of the respective fastening element 78c or 79c to the corresponding neighboring element 74c or 75c.

The neighboring elements 74c and 75c of the channel arrangement lc of the fourth exemplary embodiment each have an engagement section 87c and 86c, respectively. Each of the engagement sections 87c and 86c is designed to be able to be brought into engagement with an engagement section 11c or 12c of a stiffening element 10c, so that the stiffening element 10c

Connects neighboring elements 74c and 75c. The stiffening element 10c is identical to the stiffening element 3c. However, it is also conceivable that the stiffening elements 3 c and 10 c are designed differently.

The engagement sections 87c and 86c are located on one side of the adjacent elements 74c and 75c relative to a center M or M _{2 of} the adjacent elements measured in the circumferential direction

Engagement sections 76c and 77c. The channel arrangement 1c is thus stiffened in an area near the cover element 6c with the aid of the stiffening element 3c and in an area near the engagement sections 76c and 77c with the aid of the stiffening element 10c.

As shown in FIG. 11A, the channel arrangement 1c is towards the supporting structure

open on the circumference. However, it is also conceivable for the channel arrangement 1c to be designed in this way is that the channel arrangement lc is covered by a further cover element and / or by a further stiffening element on the side toward the support structure, so that the channel arrangement lc is closed on the circumference, at least in sections, along the channel axis.

FIG. 11B shows an expansion of the channel 96c of the channel arrangement 1c shown in FIG. 11A, so that two channels 96c and 97c which run parallel to one another are formed. The expanded configuration shown in FIG. 11B can be produced essentially with the same components as the configuration shown in FIG. 11A. With a kit that has a comparatively small number of components, different configurations of a channel arrangement with a different number of channels can be provided.

As shown in FIG. 11B, the channel arrangement 1c has a second channel 97c in addition to the channel 96c. The channels 96c and 97c run parallel to one another and, viewed in a direction parallel to a channel-side surface of the support structure (such as a ceiling surface), are arranged next to one another. With the help of the engaging portions 85c, 84c and 98c of the neighboring elements 75c, 74c and 100c, the neighboring elements 75c, 74c and 100c can be connected to fastening elements, as shown in FIG. 11A as

Fasteners 78c and 79c are shown. To simplify the illustration, these fastening elements are not shown in FIG. 11B.

Adjacent to the neighboring element 74d of the channel 96c is a neighboring element 5c of the channel 97c, which is identical to the one in the exemplary embodiment shown

Neighboring element 5 of the first exemplary embodiment (shown in FIG. 3) is formed. The neighboring element 5c therefore has no fastening section for fastening to the supporting structure, as is the case with the neighboring elements 74c, 75c and 100c. The neighboring elements 5c and 74c are connected to one another with the aid of a connecting element 99c connected, which engages in grooves or T-grooves, each of which

Neighboring elements 74c and 5c are provided. The connecting element 99c can have a double T shape, for example.

The channel 97c has the neighboring element 100c, which, relative to the channel axis of the channel 97c, is arranged opposite and parallel to the neighboring element 5c and which, in the exemplary embodiment shown, is identical to the neighboring elements 74c and 75c. However, it is also conceivable that the neighboring element 100c has a different configuration to the neighboring elements 74c and 75c.

The channel 97c is covered on a side facing away from the supporting structure by a cover element 101c, which is identical to the cover element 6c of the channel 96c.

The cover element 101c is on the outside relative to at least part of the

Stiffening element 102c of the channel 97c arranged, wherein the stiffening elements 102c and 3c of the channels 96c and 97c are identical. It has been shown that in the cross section shown in FIG. 11B, the channel 97c is no further

Must have stiffening element, since the stiffening elements 3c, 10c and 102c already provide sufficient stiffening of the orientations of the neighboring elements 100c, 74c, 75c and the cover elements 6c and 101c relative to one another.

FIG. 11c shows a further configuration of the channel arrangement 1c, in which, in addition to the channel 96c, a channel 103c running parallel thereto is provided, which is not separately fastened to the support structure (as in the case of channel 97c in the configuration of FIG. 11b). The channel 103c is formed with the aid of neighboring elements 111c and 5c, which are fastened adjacent to the neighboring element 74c with the aid of fastening elements 105c and 99c.

Each of the neighboring elements 74c, 5c and 111c each has a groove or T-groove, in which one of the fastening elements 105c or 99c engages. For example, the Fastening elements 105c and 99c, as shown in FIG. 11c, are each designed as double T elements in order to engage in T grooves of the neighboring elements fastened to one another. However, other forms of embodiment are also conceivable. The neighboring element 74c has an engagement section 112c, with the aid of which the neighboring element 74c can be fastened to the supporting structure.

The neighboring elements 111c and 5c are identical to one another and are also identical to the neighboring element 5 of the first exemplary embodiment, which was described in detail above with reference to FIG. 3. The neighboring elements 111c and 5c together form a rectilinear section of an outer contour of the channel 103c. The neighboring elements 111c and 5c are adjacent to one another, as seen in the circumferential direction of the channel 103c, without being directly connected to one another.

The channel 103c has a cover element 109c which runs parallel to the cover element 6c of the channel 96c and which, viewed in the circumferential direction of the channel 103c, connects the neighboring element 111c to a further neighboring element 110c. The

Neighboring element 110c is identical to neighboring elements 111c and 5c. The neighboring elements 111c and 110c are further connected to one another by a stiffening element 107c, the cover element 109c being arranged on the outside relatively of at least part of the stiffening element 107c.

The channel 103c also has a cover element 108c, which is designed in an angled shape so that, viewed along the circumferential direction of the channel 103c, it can be brought into engagement with the neighboring element 5c on the one hand, as well as with the neighboring element 110c. As a result, the outer contour of the channel 103c is replaced by three

Neighbor elements, namely the neighboring elements 5c, 111c and 110c, and by the

Cover elements 109c and 108c are formed. One or more of the cover elements 6c, 108c and 109c can be made transparent. As a result, one or both channels 96c, 103c can act as lighting.

FIG. 12A shows part of a channel arrangement according to a fifth

Embodiment. The channel arrangement of the fifth embodiment has

Components which are analogous to components of the first to fourth exemplary embodiments illustrated in the preceding figures, but are not necessarily identical. To simplify the illustration, these components of the fifth exemplary embodiment are therefore provided with similar reference symbols, which, however, have the accompanying symbol "d".

The channel arrangement 1d of the fifth exemplary embodiment has the neighboring elements 4d and 5d, which are each designed such that the stiffening element 3d can be brought into engagement in two different orientations relative to the neighboring elements 4d and 5d, the stiffening element 3d in each of the two orientations

Connects neighboring elements 4d and 5d. In the exemplary embodiment shown, the stiffening element 3d is identical to the stiffening element 3 of the first

Embodiment trained. However, there are other configurations of the

Stiffening element 3d conceivable. A first of the two orientations is shown in FIG. 12A. The second orientation corresponds to the orientation of the stiffening element 3 of the first exemplary embodiment shown in FIG. 1A.

When comparing the two orientations, the outside of the stiffening element 3d (seen relative to the channel axis) is interchanged with the inside of the stiffening element 3d. In order to connect the stiffening element 3d to the neighboring elements 4d and 5d in such a way that the stiffening element 3d in the second orientation (which is shown in FIG. 12A) is realistically arranged to the neighboring elements 4d and 5d, the stiffening element becomes 3d is moved from the inside to the outside by a movement, so that the engagement sections 11d and 12d of the stiffening element 3d are brought into engagement with the corresponding engagement sections which are provided on the neighboring elements 4d and 5d.

The protrusion 15d attached to each of the engaging portions 11d and 12d of the

Stiffening element 3d is provided so that the projection 15 can be brought into engagement with the corresponding engagement sections of the neighboring elements 4d and 5d in both orientations of the stiffening element 3d. In the first orientation (corresponding to the orientation of the stiffening element 3 of the first embodiment shown in FIG. 1A), the projection 15 causes a positive stop for movements of the stiffening element 3d towards the interior of the channel. In the second orientation (as shown in FIG. 12A), the projection 15 causes a positive stop for movements of the stiffening element 3d outwards.

The second orientation of the stiffening element 3d shown in FIG. 12A relative to the neighboring elements 4d and 5d with the positive stop for movements to the outside has the advantage that with the aid of the stiffening element 3d the channel arrangement of the fifth exemplary embodiment is attached to a support structure, such as, for example, to a support structure Wall or ceiling, can be attached. This is described in detail below with reference to Figures 12B and 12C.

FIGS. 12A and 12B show the channel arrangement 1d in a state in which it is fastened to a support structure 88d by means of the stiffening element 3d. With the exception of the neighboring elements 4d and 5d and the stiffening element 3d, the others are

Components of the channel arrangement 1d of the fifth exemplary embodiment are not shown in order to simplify the illustration. The connecting section 14d of the stiffening element 3d has one or more

Openings through each of which one or more fastening elements 89d, such as fastening screws, protrude. One or more are between the stiffening element 3d and the flat channel-side surface 91d of the support structure 88d

Spacers 90d arranged. Each of the spacers 90d can be one or more

Have openings, wherein through each of the openings one or more of the

Fasteners 89d protrude.

The spacers 90d are each designed in such a way that when the channel arrangement ld is fastened, the end sections of the neighboring elements 4d and 5d, seen in the circumferential direction, are pressed against the surface 91d of the support structure 88d. As a result, the neighboring elements 4d and 5d are each clamped between the surface 91d of the support structure 88d and the stiffening element 3d. As can be seen in FIGS. 12B and 12C, no cover element is arranged between the stiffening element 3d and the surface 91d of the support structure 88d.

As shown in detail in FIG. 12D, the connection between the stiffening element 3d and the neighboring element 4d is achieved by the engagement between the contact surface 23d of the projection 15 of the engagement section 11d of the stiffening element 3d and a corresponding contact surface 76d of the neighboring element 4d, and by the locking engagement between the locking portion of the end portion 1 ld of

Stiffening element 3d and the neighboring element 4d causes. The engagement between the engagement section 12d (shown in FIG. 12A) of the stiffening element 3d and the neighboring element 5d is identical. However, it is also conceivable that

different configurations are provided. It was therefore shown that the kits according to the shown
