Description

  The present invention relates to a media channel (media path structure; Medienkanal) for a laboratory system, and more specifically, a media cell (medium for supplying and / or removing laboratory media to and from a laboratory workplace). Medlenzelle), media column (media column; Mediensaure), suspended media boom (media side arm; Medienampel) or media station (media base: Medienstation).

  The flexibility and mobility of laboratory systems in the laboratory, such as the availability of laboratory media such as water, drainage, gas, compressed air, vacuum generation and power connections where needed Is guaranteed. For this purpose, the media cells, media columns, suspended media booms have so-called media channels, in which the supply and disposal of laboratory media connected to the supply and disposal facilities in the building. There is a pipeline.

  The media cell can be in the form of a cell that is brought to the wall and has a laboratory workbench in front, and must be a stand-alone cell for a laboratory workbench or a double workbench. Or it can take the form of a table top cell. Media cells supply mountings and sockets designed specifically for the media and are used as various storage systems. A media cell can have several media panels with various components. Laboratory media is received from the media panel, and the laboratory media may be removed via the media panel to a processing facility installed in the building.

  In a media column suspended from a laboratory ceiling, the media channel extends vertically through the media column.

  The suspended media boom has a number of raster cells, and the suspended media boom can be provided with appropriate media panels on both sides, like a media column. The media panel is arranged in a horizontal direction and usually extends over several laboratory benches that are mainly mobile.

  In the professional world, a media station is attached to a laboratory workplace and connected by cables and pipelines to a corresponding supply and disposal system installed in the building to supply and supply media directly. It is seen as a system for removing.

  In all these laboratory systems, the modular structure serves as a major part, since significant cost savings can already be achieved at the design stage.

  Conventional media channels for use in the laboratory system described above are produced by the method of side frames arranged at a distance from each other, as disclosed in, for example, Patent Documents 1 and 2. Depending on the height of the room system, the media channels are connected to each other by one or more cross beams. There is a clamping device on the cross beam, and raised flanges related to the media panel can be inserted into them and clamped. Cables and pipelines are provided to remove and supply media vertically through holes provided in the cross beams or horizontally between adjacent cross beams.

  The drawback with this is that the media channels, media columns, suspended media booms or uniform media channels throughout the media station have a relatively shallow depth. As a result of this, electrical connections that require a relatively deep depth structure, in particular compared to, for example, gas fittings, protrude from the media channel and / or media panel over a certain length. Further, upgrading conventional media channels using additional components (eg, device holders, support members for reagents, stand holders, etc.) is limited. In addition, the exact same media channel cannot be used for different laboratory systems because the configuration requirements of the media channel differ from the structural requirements of the suspended media boom. This results in more design, manufacturing and assembly costs.

  U.S. Patent No. 6,057,089 discloses a media cell having a wall-shaped, vertically aligned installation element, which is installed above the laboratory table worktop height using an installation pipeline and distribution connections. It is installed. The installation pipeline and distribution connection are arranged within the frame side profile on the narrow side facing the worktop, and there are closed compartments and / or panels. In this media cell, panels that can be fixed or pivoted are arranged alternately, and they are attached to the side panel by screws.

  From patent document 4, a duct board having an essentially box-shaped duct is known. The duct has a knot, and several sections extend in different directions from the knot.

  Other media channels of the same type are described in US Pat.

EP0800865A2 DE19614370C1 DE10154128A1 DE3739815A1 US5212915A US4544214A

  Therefore, its modular structure has been improved in terms of handling, versatility, upgradeability and cost efficiency compared to traditional media channels, making the media channel for laboratory systems suitable for mass production. It is an object of the present invention to provide.

  This is accomplished through media channels for laboratory systems for supplying and / or removing laboratory media to the laboratory workplace, in particular media cells, media columns, suspended media booms or media stations. Is done. The media channel has profile elements arranged in the longitudinal direction, along the longitudinal axis, ducts for laboratory media cables and pipelines and at least one panel in the form of a blank panel Or supply and / or removal side, together with at least one panel provided with at least one attachment that is functionally specified for the supply and / or removal of laboratory media. Thereby, the panel is removably fixed to the profile element by means of a connection element provided on the supply and / or removal side, the profile element and the connection element being configured as an integral and folded metal component The

  The profile element of the media channel according to the present invention fulfills two functions. On the one hand, it provides a duct for laboratory media. The structural space acquired by the cross beams in the conventional media channel can therefore be fully utilized for media supply and removal, which has advantages in terms of achieving space savings. On the other hand, the profile element already has the necessary connection elements for fixing the media panel. In addition, since it is a metal fold and the connection element to the media panel is already part of the profile element, it can also be manufactured cost-effectively and easily assembled in the laboratory . The media channel is available for a variety of laboratory systems, which results in a significant reduction in manufacturing and assembly costs.

  Preferably, the connecting element provides a non-constrained connection, particularly preferably a clamping or constraining connection, particularly preferably a snap type or swallow (Schwalbenschwanz) that secures the panel on the profile element ) Provide type.

  Preferably, the connecting element is elastic.

  According to a preferred embodiment of the invention, the connecting element extends essentially over the entire length of the profile element.

  According to a more preferred embodiment of the invention, the profile has an outer rail defined by the undercut, so that the upgradeability of the media channel with additional components is improved.

  Preferably, the rail essentially extends over the entire length of the profile element.

  Preferably, the profile element defines two ducts extending in the longitudinal direction.

  Particularly preferably, the profile element is tapered in cross section. This creates a wider space inside the media channel, which is particularly advantageous in the case of electrical connections. At the same time, the use of worktops is not limited when using this type of media channel for laboratory benches.

  In addition, on the wider side of the profile element seen in cross-section, the storage panel can be applied by non-constrained fastening means. This storage panel can be used as a storage surface for various laboratory facilities, further increasing the versatility of the media channel.

  Preferably, some panels can be fixed to the profile element in a modular fashion. This modular assembly principle allows the media channel to be attached to the panel required by the user and has the advantage that various tests can be performed such that different laboratory media are used in the exact same laboratory system.

  According to a more preferred embodiment of the invention, the panel can be attached to the profile element without gaps. This prevents the entry of fluids and foreign objects into the media channel.

  In particular, these panels may be provided with devices for supplying and / or removing water, drainage, gas, compressed air, electricity, light, as well as connections for vacuum generation and electrical data processing.

  According to a more preferred embodiment of the invention, the media channel includes a support structure that allows the profile element to be secured to the wall or ceiling, or that can be fitted to the profile element on both sides thereof. In this way, almost similarly designed media channels can be used in media cells, media columns, suspended media booms or media stations, and for laboratory builders as well as laboratory equipment manufacturers. This is an advantage from an economic point of view.

  Preferably, the support structure allows a raster-like attachment of the profile element to the support structure. This means that laboratory personnel can move the media channel in the horizontal and / or vertical direction as needed, and in the laboratory, the media channel and / or media attachment It means it can be used where it is needed.

  Also preferably there is an opening between the profile element and the support structure. Through the opening are cables and pipelines for supplying and / or removing laboratory media. In particular, in the case of electrical connection requiring a larger installation depth, the hollow space of the support structure can be used for the electrical connection cable through the opening.

  Preferably, the media channel meets the IP 44 and IP 54 protection classification requirements that are valid on the filing date. In this way, for a long period of time, the operation of the media channel is guaranteed against the ingress of moisture and dust (foreign matter). In particular, the media channel guarantees contact protection against foreign objects with a diameter> 1 mm, as well as complete protection against dust accumulation. In addition, it guarantees sufficient protection against spray water.

  Various embodiments of the present invention will now be described by way of example only with reference to the accompanying drawings.

FIG. 16 is a perspective view of the clamping device shown in FIG. 15.

  FIG. 1 shows a perspective view of a media channel 1 according to the invention with a panel 2 mounted modularly on the media supply and / or removal side. Depending on the purpose of its use, for example in a media cell, media column, suspended media boom or media station, the media channel can be arranged vertically or horizontally. If the media cable and pipeline of the building laboratory enter the media channel 1 from above or below, the lateral ends of the media channel 1 are each closed by the side panel 9. In the case where the media channel 1 being used in the media cell serves as a storage surface for laboratory instruments, a further panel 6 is provided at the top of the media channel.

  Media channel 1 described below meets the requirements of protection classification IP 44 and IP 54 that are valid on the filing date. In addition, components that are visible and / or exposed from the outside of the media channel are preferably provided with a high quality powder coating. Through the powder coating, the media channel is ideally protected against environmental conditions in the laboratory. Since each panel is mounted without tools, they can be quickly and easily adapted to changing laboratory conditions.

  Each embodiment of the media channel shown in FIG. 1 will be described later by the method of FIGS.

  FIG. 2 shows a perspective view of a suspended media boom having a support structure 20 for mounting to the ceiling. The support structure 20 has support columns 22 such as two rasters. Here, depending on the length of the support column 22, the support column is stabilized by means of one or more transverse beams 26. The lower end of the support column 22 is attached to the media channel 1 on both sides.

  In the example shown in a very simplified form in FIG. 2, the two media channels 1 are only provided with blank panels. Since both media channels 1 are tapered in cross-section, the panels are tilted with respect to a support column 22 which is vertical. This is the case, for example, when the panel is equipped with a device for tapping laboratory media that is a connection for generating water, drainage, gas, compressed air, electric light, or vacuum and for data processing. Make handling easier. If further required, each media channel 1 can be attached to a support projection 24, although with different dimensions. In the example shown in FIG. 2, each support protrusion 24 in the horizontal direction is connected to a storage partition 29. Media supply from the building to each media channel 1 is through a vertical shaft 28.

  FIG. 3 shows a very simplified form of a media cell containing a dual laboratory workbench. Both laboratory worktables 30 each have a laboratory worktop 32. The laboratory worktops 32 are adjacent to each other with no gaps in the region of the support structure 20a for the media channel 1. The support structure 20a has two side supports 22a that are slightly separated from each other so as to essentially correspond to the width of the laboratory worktop 32. These laboratory worktops 32 are standing on the laboratory floor so as to be level. The length of the side support 22a is set so that the media channel 1 extending between the side supports 22a is arranged approximately at the chest level of laboratory personnel. However, a raster-like design of the side support 22a allows various settings of the height of each media channel 1. In the case of the media cell shown in FIG. 3, the supply and removal of laboratory media to and from the building takes place through shaft 28a. Even if not explicitly shown in FIG. 3, those skilled in the art will recognize that the media cell can be supplemented with other media channels and / or other laboratory equipment.

  FIG. 4 shows a double side media column attached to the ceiling or a protruding part of the building from the ceiling by means of the support structure 20b. In the example of the media column shown in FIG. 4 in a very simplified form, the support structure 20b has a horizontal support rail 23b that is connected to each side support post 22b. Depending on the required spatial spacing for the media channels 1, both support posts 22b can be moved along the support rails 23b. After the required space is obtained between the two media channels, they can be connected to each other via a storage panel 29b. As shown in FIG. 4, the cross-section of the two media channels is conical (tapered), so that each media channel 1 provided with a laboratory media supply and / or removal device is more It becomes easy to approach easily.

  FIG. 5 shows a rear perspective view of a media channel 1 according to the present invention having a support structure 50. As shown in detail in FIGS. 6A and 6B, the media channel includes a profile element 100. A modular panel 2 can be attached to the profile element 100 in a schlussig and kraftschlussig manner. The upper side of the profile element 100 is closed by the storage panel 6.

  In addition to the profile element 100, the media channel shown in FIG. 5 also has a support structure 50 for mounting to a wall. The fixing to the wall is performed via a fixing flange 54 protruding in the transverse inner direction. At the bottom, the support structure has a base plate 52 that is rigidly fixed to a fixing flange 54. An opening 59 is disposed between the profile element 100 and the support structure 50. This means that in addition to the interior of the profile element 100, the internal space defined by the support structure 50 can be utilized for the supply and / or removal of laboratory media.

  The support structure 50 has vertical struts 58 that are spaced apart from each other in the horizontal direction. A profile element 100 can be attached to the vertical column 58. The raster-like design of the support structure 50 allows a high level of versatility for securing the profile element 100 to the support member 50. The support structure 50 has one or more pedestals 56 arranged at a distance from each other in the horizontal direction. The pedestal 56 functions as a support / base for a storage panel (not shown) for closing the top of the support structure 50.

  FIG. 6A shows a front perspective view of the profile element 100 shown in FIG. 5 with an enlarged detail view of the circled area of the profile element 100. The front side in FIG. 6A will be referred to as the supply and / or removal side of the profile element 100 in the following.

  The intermediate base 110 extending in the longitudinal direction of the profile element 100 divides its profile (profile) into two ducts 102 and 104 for media supply and / or removal. For example, the duct 104 can be used for thin tubes / pipes for vacuum generation or for electrical and data cables. On the other hand, the duct 102 can be used for water, drainage or gas pipelines. In the intermediate base 110, the openings 112 are arranged at regular intervals in the length direction of the profile element 100. The opening 112 connects the duct 102 and the duct 104. The column 106 extending in the vertical direction in FIG. 6A is for fixing the profile element 100 to the wall or the support structure 50 shown in FIG. On the back side of the profile element 100, there is a flange 108 that protrudes in the vertical direction from the intermediate base 110 and is continuous in the longitudinal direction. The flange 108 functions as a holding base for the storage panel 6 shown in FIG. On the supply and / or removal side of the profile element 100, connecting elements 121 (FIG. 6A), 125 (FIG. 6B) are arranged for fixing the panel 2. The enlarged views in FIGS. 6A and 6B show the detailed structure of the connection elements 121 and 125.

  The connecting element 121 is formed by an S-shaped part 122 and an L-shaped part 120. Since both parts 122 and 120 are pre-tensioned, when introducing the components to be clamped, the flanges 3 of the respective panels 2 (FIG. 7) projecting sideways more specifically from the panel surface are introduced. When doing so, the two parts 122, 120 spread apart and come into contact with and clamp the relevant components to be clamped. The function of the connecting element 121 is similar to that of a spring clip. On the bottom side, the profile element 100 has a base 114 that is adjacent to the rail 117 formed by the two undercuts 116, 118 and projects to the inside of the profile element. On the wall side, the base 114 is connected to two vertical struts 106. The purpose of use of the rail 117 is described with reference to FIGS.

  FIG. 6B shows the profile element shown in FIG. 6, but this time is a perspective view from the back. The encircled area is shown in detail in the enlarged view and shows the structural design of the connecting element 125. The connecting element shown in FIG. 6A within the upper portion of the profile element 100 and shown as a lateral boundary on the supply and / or removal side of the duct 104 forms a portion 124 that forms a sharp angle with the L-shaped portion 126. And is formed by. As in the case of the connecting element 121, since the two parts are pre-tensioned, these functions are also similar to the functions of the spring clip.

  The portion 130 functions as a holding platform for the storage panel 6 shown in FIGS. Portion 130 is surrounded by a double wall to increase bending stiffness. The portion 130 prevents deformation when a positive restraining force is applied to the support panel. The adjacent portion 124 is an intermediate base 110 and has an opening 112, as already described in connection with FIG. 6A. The intermediate base is connected to the vertical column 106.

  The profile element 100 shown in FIGS. 6A and 6B is designed as a folded metal component and is therefore integral. Therefore, it is suitable for mass production. In this respect it should be pointed out that the profile element can also be made of plastic components exhibiting the required bending stiffness.

  FIG. 7 shows a perspective view of the panel 2 with flanges 3, 4 and 5 projecting at an angle of 90 ° at the ends. The flange portions 2 and 4 are clamping portions for insertion into the connection elements 121 and 125. The flange portion 5 functions as protection for preventing intrusion of fluid or foreign matter into the closed media channel 1 shown in FIG. The panel in FIG. 7 is shown without a device for media supply and / or removal. The function specific panel 2 will be described later with reference to FIGS.

  FIG. 8 shows a cross-sectional view of the storage panel 6, and the storage panel 6 can be inserted into the portions 108 and 130 shown in FIGS. 6A and 6B in an unconstrained manner. The storage panel 6 has two joined portions 7, 8 that can be non-restrictively connected to the portions 108, 120 as shown in FIG. The cross section of the engaging portion 8 is L-shaped, while the cross section of the engaging portion 7 is V-shaped.

  FIG. 9 shows a cross-sectional view of the media channel. The media channel includes a profile element 100 and a panel 2a with a water attachment 2a '. The supply pipeline 2 a ″ to the water mounting portion 2 a ′ initially passes through the support structure 50 and is oriented across the duct 102 to the water mounting portion 2 a ′. Storage panel 6 is assumed to be at the top of profile element 100 and is used as a storage surface for laboratory equipment when media channels are used in the media cell. Two ducts 102, 104 are also clearly shown.

  The profile element 100 is fixed to the support structure 50. The interior of the support structure 50 can be utilized in addition to the ducts 102, 104 for water supply and removal. Under the profile element 100, there is a screen 46 on which a sink 42 is installed, and a drainage channel 44 of the sink 42 also passes through the inside of the support structure 50.

  The upper end of the screen 46 shown in FIG. 9 passes through a recess such as a slit shown in FIG. 5 and provided in the base 114 (FIG. 6A).

  Both screen 46 and panel 2a meet the requirements of protection classifications IP 44 and IP 54 to prevent ingress of fluids and foreign objects into the media channel and support structure.

  FIG. 10 shows a further example of a panel 2b with a socket 2b '. In order to prevent the ingress of fluid and avoid a short circuit, the appliance is housed in a sealed casing 2 b ′ arranged in the duct 102. The duct 104 further includes media cables and pipelines, only schematically shown here, for media supply and / or removal. The upper side of the profile element 100 is also closed by the storage panel 6.

  The panels 2a and 2b shown in FIGS. 9 and 10 are equipped with a water mounting portion 2a 'and an electric socket 2b' as examples. Depending on requirements, each panel corresponds to a different laboratory media (for example water, drainage, gas, compressed air, electricity, light, together with connections for vacuum generation and connections for electrical data processing) The device can of course be equipped.

  11 to 15 show an example of the use of the rail 117 shown in FIG. 6A. 11-14, the profile element 100 is attached to a rail 20c, such as a raster, purely by way of example. The profile element 100 can of course be fixed relative to differently designed support structures. The upper side of the profile element 100 is closed by the storage panel 6. On that side, ie on the supply and / or removal side of the profile element 100, each panel 2 is arranged. A screen 46 is arranged below each panel 2 and above the worktop 32.

  Various additional components can be removably secured in the rail 117 by means of the clamping device shown in FIGS. These additional components include a pipette holder in FIG. 11, a storage surface 70 in addition to the storage panel 6 in FIG. 12, a so-called drip board 80 for various laboratory vessels in FIG. 13, and a monitor in FIG. For example, it includes a monitor holder 90 for mounting a flat screen, and in FIG. 15, an intermediate wall for preventing water droplets.

  The clamping device 200 will be described in more detail with reference to FIGS. The clamping device 200 includes a clamping shoe 206 along with a clamping tab 204. The clamping tab 204 can be moved relative to the clamping shoe 206 within the rail 117 by means of a star knob 202. In order to clamp the clamping shoe in the rail 117, the star knob 202 is turned clockwise. As a result, the portion on the screw of the star knob comes into contact with the undercut portion 116, while one clamping tab 204 and the adjacent portion of the other clamping shoe 206 are pressed against the undercut portion 118. The The clamping shoe 206 is provided with a clamping adapter suitably designed to mount the monitor holder 90, drip board 80, storage surface 70, pipette holder 60 or other additional components required in the laboratory. can do.

  The media channels described above are not limited to the shapes shown. For example, the media channel, and more specifically the profile element of the media channel, can be designed in a checkerboard fashion so that the corresponding panel can be connected to the profile element.

  The conical and linear cross-section at the top of the media channel provides more room, especially for electrical installation elements, so that they are housed in a moisture-proof sealed casing for short-circuit prevention purposes be able to. At the same time, when using the media channel in the media cell, the tapered side of the media channel ensures that the complete surface area of the worktop is available for experimentation. However, to achieve these two objectives, other cross-sectional shapes, such as a convex shape in a conical state, are conceivable.

  Furthermore, the connecting element is not limited to an elastic clamping device. Those skilled in the art will appreciate that other constraining and non-constraining connection methods can be used to achieve the same effect (ie, simple removable fixation). These examples are snap-type, swallowtail, and can be fixed with magnets.
