Definitions
- the invention relates to a device for guiding elongated strands, such as cables, hoses or the like, through an opening in a panel, for example the wall of a switch cabinet or the like, according to the type defined in more detail in the preamble of claim 1.
- the device itself comprises a divided frame, which comprises a substantially U-shaped lower frame part and a frame cover.
- U-shaped refers to the fact that this U, which is formed by a base and two outer legs, often also has intermediate webs which are connected or connectable to the base parallel to the two legs of the U inside the U are.
- the frame cover can essentially have the same shape as the frame base, as is the case, for example, in the documents mentioned.
- frame covers are also conceivable which close the U as a substantially flat cover.
- Elastic grommets are then inserted into the chambers of the frame, which typically have a hole or several holes for accommodating cables exhibit. These elastic grommets are often slotted, so that the opening in the elastic grommet intended to accommodate the cable, the hose or the like is connected to one of the side edges via a slot, so that pre-assembled cables with plugs that are already fitted, hoses with plugs that are already fitted Hose couplings and the like can be inserted into the grommets that can be folded up for this purpose.
- the spout Due to the elasticity of the spout, it can then be closed accordingly around the elongate strand and pushed into the chamber, in which it typically sits in a form-fitting and sealing manner and, when the lid is installed, sealing both with the walls of the chamber or the frame and with the elongated strand is pressed. This ensures a very good seal and at the same time strain relief for the strand.
- this structure of the device is preassembled with the frame, the grommets and the inserted elongate strands.
- dummy grommets can also be inserted as grommets without an opening in order to be able to cover a large number of applications with as few frame sizes as possible.
- the chambers can accommodate grommets of different sizes, for example to be able to guide a cable or several cables or strands through a grommet or the like. All of this results essentially from the prior art mentioned above.
- the lower frame part and the frame cover are then screwed together or, in the case of the last-mentioned prior art, clipped together.
- This assembly is then mounted to a panel or wall of a control cabinet via screws, typically with a gasket placed in between.
- the frame then sits sealingly around an opening in the plate and thus ensures that the elongate strands can be introduced tightly and without strain into an installation space enclosed by the plate, for example the control cabinet already mentioned several times.
- the plate is typically made from a correspondingly thin material, for example sheet metal.
- For attachment using The usual screws shown in the prior art must therefore be kept on the opposite side of the plate, ie the side facing away from the assembled frame, a nut, possibly with appropriate washers, which makes assembly of the frame relatively complicated.
- the object of the present invention is now to specify an improved device according to the preamble of claim 1, which in particular avoids the disadvantages mentioned.
- the devices for fastening the frame to the plate in the area of the frame are no longer designed as bores for receiving screws. Rather, these are inventively designed with hooks for attaching the frame in the opening of the plate or in mounting holes in the plate. At least one of the hooks is part of a connecting link element or is moved indirectly by such a connecting link element, which can be moved relative to the frame via at least one fastening element transversely to the running direction of the received elongated strands.
- One or preferably two link elements are thus formed in the frame and interact with one or preferably also two other hooks by the hooks moving relative to one another.
- the fastening element allows the at least one link element to be moved with the hook transversely to the running direction of the received strands.
- the hook connected to the link element can be moved via this one attachment element per link element, typically two attachment elements for a typical frame size. It can move towards at least one fixed hook or away from it, depending on the type of actuation of the fastening element, ie a loosening or fastening in the plane transverse to the running direction of the received elongate strands.
- the frame can be fixed in the opening of the panel by bracing the hooks with the panel without having to be accessible from the opposite side of the panel, as is typically the case in the prior art.
- Transverse to the running direction of the picked up elongate strands can on the one hand mean parallel to the plate, i.e. at an angle of approximately 90° to the running direction of the picked up elongate strands, or can also be at an angle to it, i.e. for example at 60° to the running direction of the picked up elongate strands , as long as at least one component of this transverse direction has a motion component along the plate.
- the link element can thus be moved directly along the plate or more or less obliquely away from it or towards it along the plate.
- the other hooks can also be movable or preferably stationary.
- a movement in the transverse direction is conceivable as well as - alternatively or additionally - a mobility parallel to the running direction of the inserted strands, for example to influence the height of the hooks above the frame or this via another screw from the front side of the To be able to loosen or tighten the frame if necessary. This allows tolerances in the frame and in particular in the plate or the opening to be compensated.
- all the hooks to be able to move relative to one another and/or relative to the frame as part of link elements or indirectly through link elements. For example, two link elements could be moved towards or away from each other simultaneously when screwing by a fastening element in the form of a screw with a left-hand thread at one end and a right-hand thread at the other end.
- a very favorable variant of the device according to the invention can provide that the fastening element can be releasably connected to the link element.
- this can be realized via the screw/thread or threaded rod/thread combination, i.e. in such a way that the fastening element is designed as a screw or comprises a threaded rod which at least indirectly interacts with a thread of the connecting link element.
- clipping or latching a connection via a bayonet lock
- a connection that can be made and released by turning in which, unlike with a thread, there is a relatively small angle of rotation of less than 360°, preferably less than 200° enough, or something like that.
- the element used for the connection can be supported in its mode of operation by a spring or resilient parts of the elements.
- the fastening element is designed as a tensioning element or has one.
- the fastening element for fastening the cover and for simultaneously moving the link element can therefore be a tensioning element.
- Lever clamps, toggle clamps or the like are conceivable here.
- the tensioning element can also be combined with a threaded rod, so that this is screwed into the connecting link element and the same is moved over part of its path transversely to the direction of travel of the elongated strands, after which tensioning of the tensioning element covers the rest of the way to securely fix the hook of the link element and the cover is put back.
- the clamping element can be designed as an eccentric clamping lever.
- An alternative to this can also be a different type of detachable attachment, for example between a rod and the link element or a projection of the link element and the tensioning element.
- the frame for example the lower frame part, has at least one recess for the connecting link element on its rear side facing the plate in the assembled state.
- the link element can be pushed into this recess transversely to the running direction of the inserted elongate strands or clipped in the running direction of the inserted elongate strands.
- the link element can then be moved in the recess transversely to the direction of travel of the inserted elongated strands, for example along the longest axis of the respective leg of a part of the frame, via the fastening element, eg in the form of a thread/screw combination.
- This allows the distance to the other, eg in the plane of the plate stationary, hooks to be changed, so that the frame can be hooked over the hooks, for example in the opening itself or in holes next to the opening, which are the case with conventional structures have been used so far, can be braced.
- the possibility of inserting the hooks into these holes and tightening the frame in the holes is advantageous for retrofitting existing systems with the new devices, since these also have other advantages in addition to simple assembly and disassembly in accordance with the following configurations from one side of the plate.
- the link element can be moved via the fastening element, which is accessible from a front side facing away from the panel in the assembled state of the frame.
- the connecting link element can preferably have a thread which is accessible from a front side which faces away from the plate in the mounted state of the frame and which forms part of the thread/screw combination.
- the required screw or threaded rod, which in particular can also be part of a tensioning element, is therefore accessible from the front.
- the central axis of the thread is formed obliquely to the running direction of the inserted strands and obliquely to a central plane of the plate around the opening.
- the central axis of the thread and thus the central axis of the screw can therefore be arranged at an angle in this particularly favorable embodiment. This makes extremely good accessibility possible, for example by means of a cordless screwdriver, even when the frame is mounted on the plate or when the frame is mounted on the plate.
- this sloping arrangement of the screw enables a very simple structure of the connecting link element in the recess, since it slides easily and efficiently transverse to the running direction of the cable in its recess due to the sloping engagement of the screw and thereby reliably holds the frame in the opening or the mounting holes of the plate tense.
- the recess for the link element is designed in the respective part of the frame such that the link element moves transversely to the running direction of the inserted elongated strands at an angle to the plane of the plate. Such a movement obliquely to the plane of the plate, preferably obliquely away from the plate, can have some advantages.
- the friction in the structure can be minimized, in particular in a combination of the oblique thread and preferably an aligned alignment of the movement on the one hand and of the thread on the other hand.
- the hook is moved towards the material of the plate on the one hand and on the other hand in the plane towards the edge of the opening or the bore in the plate. So, in addition to the direction of movement along the plate, it has a further movement component perpendicular to the plate.
- the frame can now be easily and securely fixed in an opening via the fastening element and the link element.
- the frame can be equipped with cables and grommets and closed.
- the frame parts can be clipped or screwed together in a conventional manner.
- the frame is then attached to the opening in the manner described by moving at least one link element with its hook relative to another hook.
- An extraordinarily favorable development of the device according to the invention can additionally provide that the fastening element and a receptacle for the fastening element in the frame are designed in such a way that the fastening element interacting with the link element connects the frame cover to the frame lower part and the link element with its hook transversely moved to the running direction of the inserted elongate strands relative to at least one of the other hooks.
- this structure which can be realized, for example, with the screw positioned diagonally opposite the plate or with a tensioning element as the fastening element, both the fastening of the frame to the plate and the fastening of the frame cover to the frame lower part and thus the pressing of the inserted grommets can be achieved easily realized with the elongated strands.
- both the secure and reliable closing of the cover and the Attachment of the frame to the plate can be realized.
- Something similar would also be conceivable, for example, with two L-shaped frame parts, so that the frame cover and the frame lower part are each of the same design and the screws are therefore diagonally offset from one another.
- Two U-shaped frame parts could also be used here.
- the attachment for example in the form of a screw connection, can be easily tightened or loosened using a cordless screwdriver.
- clamping elements such as clamping levers, this could even be implemented without tools. This makes it possible to completely assemble the frame, including the inserted grommets and strands, with just two fastening elements, and this with good accessibility of the fasteners at an angle to the plate and the direction of travel of the elongate strands.
- the frame parts each have a recess for one of the movable connecting link elements in their section facing the respective other frame part.
- This can then preferably be movable along the axis of at least one leg of the respective frame part or at an angle thereto.
- the sections of the frame facing away from the respective other frame part can have the additional, e.g. stationary, hooks.
- both a movable and a stationary hook are arranged on each of the legs.
- a further stationary hook can be provided centrally, for example in a base or cover area of one of the frame parts.
- the further hooks can be formed by connecting link elements which are introduced into recesses in the frame parts and do not move appreciably transversely to the running direction of the strands inserted.
- the quasi-stationary hooks can thus be implemented simply and efficiently using the same connecting link elements that are also used to design the movable hooks. Nevertheless, a certain tolerance compensation is possible through minimal movements.
- This can be correspondingly favorable, for example, in the case of link elements and hooks produced by die casting.
- such elements made of die-cast zinc or die-cast aluminum, which have a relatively higher stability than those made of Have plastic are introduced into a frame otherwise made of plastic or a fiber-reinforced plastic
- connecting link elements themselves from plastic, preferably a fiber-reinforced plastic, or to realize them as sheet metal parts by stamping and forming.
- production by machining, for example from a metal would also be conceivable.
- the additional hooks are designed in one piece and fixed in place with one or the respective frame part, e.g. be realized as part of this lower frame part.
- the design can be realized with a fiber-reinforced plastic or with a previously inserted insert made of a stronger plastic material, metal or the like when the frame is produced by injection molding.
- Such an insert would also fall under the concept of one-piece in the sense of the invention, since such an insert is permanently and firmly connected to the frame after production because it is inextricably encapsulated by the material of the frame and thus in the sense of the present description is considered integral.
- the slope of the central axis of the thread can preferably be arranged at an angle of approximately 20 to 60° to the plane of the plate.
- Such an angle of preferably a little less than 45° ensures reliable movement of the link element transversely to the running direction of the cable when screwing.
- reliable pressing of the grommets and reliable pressing of the frame cover onto the frame base and/or vice versa can also be achieved through an angle of more than 30°.
- sealing elements are arranged between the frame cover and the lower frame part of the frame, for example injected seals made of an elastomeric material, or also labyrinth seals made of the material , from which the cover and the frame are made anyway.
- the hooks themselves can have engagement surfaces for contacting the plate in the assembled state of the frame, which are aligned obliquely to the plane of the plate.
- Such contact surfaces of the hooks running obliquely to the plane of the panel in which case an incline of, for example, 10 to 20° can be useful here, allows reliable mounting of the frame on panels with a certain variation in thickness.
- the plates which are typically designed as sheet metal in machine controls or switch cabinets, have thicknesses in the order of magnitude of 1.5 to 3 mm, for example.
- the thickness is never exact due to a coating or the like, so that the incline of the contact surfaces and a corresponding movement when tightening the screws and moving the connecting link elements that is a little further or less far can achieve an adjustment to this thickness, so that independently from the exact thickness of the panel, a very reliable and stable attachment of the frame to the panel is possible.
- This sloping contact surface is particularly crucial when the movement of the link element is parallel to the plane of the plate.
- this embodiment variant can be helpful, but is not absolutely necessary. Therefore, according to a favorable further development of the device according to the invention, it can also be provided that at least one of the hooks has an engagement surface running essentially parallel to the plane of the plate.
- this design can also be sufficient. In particular with small dimensions of the hook, even better attachment can be achieved in this way since, unlike with an inclined contact surface, the risk of the hook slipping off the material of the panel is minimized.
- seals are also formed between the frame and the panel around the aperture or around the bores to seal the structure from the environment Structure which can react easily and efficiently to different plate thicknesses and surface textures of the plate, so that the device can be safely and reliably mounted on the plate and reliably fastened and sealed in relation to it in almost all cases occurring in practice.
- the frame part can have two legs and at least one intermediate web between the two outer legs, so that at least two or more chambers for receiving the grommets are formed.
- This structure would also be analogously conceivable for a frame with two L-shaped frame parts, each of the frame parts then having one of the legs and at least one intermediate web.
- the dividers could also be realized in half in the respective frame parts and would then be added to the complete divider during assembly in the center of the frame.
- This structure with intermediate webs which is known in principle from the prior art, can also be correspondingly implemented in the frame of the device. It can, according to a very favorable development of this idea be provided that one of the frame parts, in particular the frame cover, is screwed in the region of the at least one intermediate web or at least one of the intermediate webs to the respective other frame part, in particular the lower frame part. This can be done both via a link element with or without a hook and also via a thread introduced directly into the intermediate web, either in the material of the intermediate web or in a threaded sleeve introduced in the intermediate web.
- this additional screw is also inclined both to the running direction of the inserted elongated strands and to the plane of the plate, preferably at approximately the same angle as the screws for actuating the link elements and in particular also for fastening the frame parts to one another, i.e. for closing the frame .

- FIG. 1 A three-dimensional view of the device 1 can be seen in the illustration in FIG. It consists essentially of a frame 2, in which several grommets 3 are accommodated.
- the eight grommets in the exemplary embodiment shown here are made of elastic material and each have a central opening through which an elongate strand 4 can be inserted.
- the elongate strands 4 are indicated here in sections as cables.
- the device 1 could just as easily be used to feed through hoses or the like. Different openings can also be implemented in the grommets 3 for different types of cables, so that the round cross-sectional shape of the cables shown here is to be understood purely as an example.
- Each of the spouts 3 has a slot 5 on the side, which connects the opening in the center of the spout 3 to the outer edge. This allows the grommet 3 to be opened up so that longer cables can also be inserted without having to thread the grommet over the cable.
- prefabricated cables with plugs or corresponding hoses for example with welded-on hose termination elements or the like, can also be introduced in this way.
- these grommets are then inserted into chambers 6 of the frame 2, which can be seen in FIG. 3, and are held in the frame 2 with a form fit.
- the frame 2 consists of a lower frame part 2.1 and a frame cover 2.2.
- the lower frame part is essentially U-shaped here and has a base part 2.3 and two lateral outer legs 2.4, 2.5.
- the base 2.3 forms the U-shaped basic structure of the frame 2 with the legs 2.4 and 2.5.
- This frame 2 with the grommets 3 is then fitted around an opening 7 in a plate 8, this opening 7 being indicated in two different ways in the representation of FIG. 2 as an example.
- a sealing element 9 is also arranged between the plate 8 and the frame 2 in order to seal the structure accordingly, so that the opening 7 through the attached frame 2 and the sealed chambers 6 in the frame 2 via the grommets 3 and the inserted cables are correspondingly tightly closed becomes.
- grommets 3 of other sizes are also conceivable.
- a grommet the size of four individual grommets could be introduced here.
- this may have a larger opening for a thick cable, pipe or the like, or may have multiple openings within a single grommet.
- these openings are preferably each individually connected to the edge of the spout 3 via a slit 5 accordingly. This is as far as known from the state of the art and can be used here analogously to this state of the art.
- grommets 3 without a hole and slot 5 can also be used.
- Such blind grommets or also conventional grommets which have been provided with a blind plug instead of the cable, then merely seal the structure without an elongate strand 4 being passed through them.
- a smaller number of five cables or the like could also be introduced and up to three more cables could be retrofitted if necessary.
- the plate 8 is typically a sheet metal plate, which represents the wall of a machine controller or a switch cabinet or the like. It is typically a few millimeters thick and the frame 2 is attached to it as previously described.
- a central opening 7 for the cable is known, as can be seen on the left in FIG.
- typically four bores 10 are distributed around the opening 7, through which the frame 2 is correspondingly fastened in the embodiment according to the prior art with screws and nuts arranged on the other side of the plate 8.
- This construction of the opening 7 with the bores 10, as can be seen on the left in the illustration in FIG. 2, can also be used for the device 1 according to the invention.
- the slightly larger opening 7 shown on the right in the illustration in FIG. 2 on the plate 8 can be used correspondingly without the bores 10 .
- both the attachment of the cover 2.2 on the frame base 2.1 and the attachment of the frame 2 in the opening 7 or the holes 10 can be achieved with only two screws 11 as fasteners.
- screws 11 which are arranged, for example, at an angle of about 40° obliquely to the plane of the plate 8
- both the attachment of the Frame 2 on the plate 8 done in the manner described in more detail later and the cover 2.2 can be firmly connected to the frame base 2.1.
- the forces required here only slightly exceed the forces required for the conventional structure, since the force for pressing the cover and the force for attachment to the plate 8 add vectorially due to the inclined position of the screws 11, so that the resulting force in the direction of the screws 11 is smaller than the sum of the previously required forces.
- hooks 13, 14 are designed in such a way that at least one of the hooks, here the hook 13, as indicated by the double arrow, can move along the plane of the plate 8, ie transversely to the running direction of the strands 4 inserted. This movement is achieved in that the hook 13 is part of a link element 15 shown in FIG.
- the detailed arrangement of this structure can be better seen in the view from the rear of the frame 2 in FIG.
- the cover 2.2 of the frame 2 is shown in the unassembled state.
- Two link elements 15 are located in two recesses 17 of the two legs 2.4 and 2.5 of the lower frame part 2.1.
- the link elements 15 with the movable hooks 13 sit in the recesses 17, which are designed in such a way that the link elements 15 can be clipped in, for example, from the rear of the frame 2, but then sit captively in the recesses 17 after clipping, and in particular in the direction the back can no longer be pushed out of these.
- the recesses 17 are also so large that the link elements 15 can be moved along the longest axis of the legs 2.4 and 2.5 in order to be able to realize the movement of the movable hook 13 already shown in FIG.
- the screws 11 introduced at an angle in the cover 2.2 of the frame 2 now pass through openings 18 in the area of the link elements and can be screwed into the thread 16 .
- a funnel-shaped guide 19 is mounted in front of the thread 16 in the connecting link element 15, as can be seen in the illustration in FIG.
- the cover 2.2 is then pressed onto the lower frame part 2.1 on the one hand and the link element 15 in the respective leg 2.4, 2.5 is then pulled in the direction of the cover 2.2 and thus in the direction of the edge of the opening 7 or the bores 10 on the other.
- the other hooks 14 are here, for example, arranged in a stationary manner in relation to the lower frame part 2.1, so that the movement of the movable hooks 13 fix the frame 2 to the plate 8 accordingly when the screws 11 are tightened.
- the general mobility of the link element 15 in the recess 17 also allows tolerance compensation.
- FIGS. 7 and 8 the structure shown in FIG. 6 can be seen again in a side view and in a sectional view through one of the legs 2.4.
- the hooks 13 and also the hooks 14 have an engagement surface 21, which is provided with a reference number in FIGS.
- This contact surface 21 with an inclination of about 10 to 20° relative to the plane of the plate 8 causes different material thicknesses of the plate 8 to be compensated and that the frame 2 can be reliably fixed to plates 8 of different thicknesses.
- the hooks 13, 14 also have an insertion bevel 22, so that they can be inserted more easily into bores 10, particularly when mounting, because in particular the movable link element 15 may be correspondingly in the recess 17 during insertion due to the insertion bevel 22 moved to simplify assembly.
- the hooks 13, 14 are positioned in the opening 7 or the bores 10, they are moved away from each other again by tightening the screws 11 through a movement of the movable link elements 15 in the recesses 17 and thus brace themselves with the plate 8, whereby the inclined contact surface 21 on the one hand the frame 2 is pulled in the direction of the plate 8 and on the other hand different material thicknesses of the plate 8 can be compensated.
- the connecting link elements 15 with the movable hooks 13 in the illustrations of FIGS. 6 and 8 are largely shown in their end positions in the assembled state. In the position shown here before the actual assembly, these would in practice lie further down in Figure 6 and further to the left in Figure 8 in the recess 17 and would only be clamped into the corresponding position by tightening the screw 11, whereby on the one hand the frame 2 reliably attached to the plate 8 and the frame cover 2.2 is reliably attached to the frame base 2.1 and the grommets 3, which are not shown here, are pressed into the frame 2 with the inserted strands 4.
- the structure as shown in FIGS. 6 to 8 has the advantage that the use of connecting link elements 15 means that the same components can be used both for the movable hooks 13 and for the additional hooks 14 .
- the frame 2 is made of plastic, for example, then, depending on the plastic material, the stability of the link elements 15 and the hooks 13, 14 may not be sufficient, so that, for example, link elements 15 made of die-cast, for example zinc or die-cast aluminum, can be used.
- link elements 15 made of die-cast for example zinc or die-cast aluminum
- the use of a sheet metal element or a plastic part provided with a corresponding reinforcement, for example a fiber reinforcement would be fundamentally conceivable.
- the other hooks 14 can also be connected directly to the lower frame part 2.1 in a non-movable and stationary manner or can be formed in one piece with it.
- This embodiment variant is shown again in the representation of FIGS. 9 and 10 analogous to the representation in FIGS.
- the hooks 14, which are arranged here in a fixed position relative to the frame 2 are formed directly from the material of the legs 2.4 and 2.5.
- the movable hooks 13 are in turn formed in the link elements 15 and act in the above described way.
- the structure essentially shows a part of the leg 2.4 of the lower frame part 2.1.
- the recess 17 is designed obliquely, preferably approximately at the angle obliquely with respect to the plane of the plate, in which the thread 16 is also oblique.
- This angle can be, for example, 20 to 60°, preferably 30 to 45° relative to the plane of the plate.
- the link element 15 is moved by the screw 11, not shown here, in the thread 16, as shown by the double arrow, together with its hook 13 obliquely to the plate level and transverse to the running direction L of the inserted elongated strands. This leads into in practice that the friction between the gate element 15 and the material surrounding the recess 17 can be reduced.
- a movement component of the hook 13 can be achieved both in the plane of the plate 8 and perpendicularly thereto. This also makes it easier to fasten the frame 2 if there is a sharp-edged opening in the plate 8, since the hook 13 no longer generates a force component in the direction L of the elongated strands 4 that are later inserted, not only through the incline of its contact surface 21, but also through a component of movement running perpendicularly to the plane of the plate 8 , which stems from the oblique movement of the link element 15 . For this reason, and as is indicated in the illustration in FIG. 11, the sloping contact surface 21 can be dispensed with.
- the attack surface is here formed parallel to the plane of the plate 8 and is therefore denoted by 21 1 to distinguish it.
- the recess 17 can be designed in such a way that the recess is so large in the area shown on the left in FIG. 12 that the link element 15 can be inserted can be. It can then be moved accordingly on an inclined plane, which only has a slot designated 23, through which the hook 13 protrudes and along the slot 23 transversely to the direction L of the inserted strands 4, and at an angle of here, for example, approx. 30 ° to the plate 8 level, can be moved.
- the sloping contact surface 21 As an alternative to the varied contact surface 211 , the sloping contact surface 21, as shown in the previously described figures, would of course also be conceivable here in order to generate another force component in addition to the movement component of the link element 15 and the hook 13 through the sloping contact surface 21 component to achieve in the direction L of the inserted strands 4.
- an alternative structure of the frame 2 can now be seen analogously to the representation in FIG. 3, but without the plate 8 being shown again.
- the cover 2.2 of the frame 2 and the lower frame part 2.1 are realized here with a part of the same size in each case, which forms the chambers 6 for receiving the spouts 3 (not shown here).
- the frame 2 is divided here approximately in the middle into two U-shaped frame parts.
- FIG. 14 an embodiment can also be seen which is also conceivable in all of the exemplary embodiments that have already been explained and are still shown.
- the frame 2 is fastened in the opening 7 of the plate 8 here via the screws 11, the link elements 15 and hooks 13, 14.
- the two frame parts 2.1 and 2.2 are connected via a screw connection 28 that is indicated.
- two screws are arranged in the area of two of the intermediate webs 2.6, 2.8.
- the closed frame 2 provided with cables 4 and grommets 3 is then fixed in the opening 7 of the plate 8 by means of the screws 11 and the hooks 13, 12.
- FIG. 15 A further alternative of the device 1, again in a representation analogous to that in FIG. 3, is shown in FIG.
- the structure there largely corresponds to the structure shown in FIG. 3, so that the parts designated and described there are not described again, but only be provided with the same reference number.
- these clamping elements 24 are designed specifically as eccentric clamping levers.
- the clamping element 24 consists of the actual eccentric lever 25, a clamping element 26, which can be moved towards or away from the eccentric lever 25, and a rod 27, which can be seen in FIG then screwed into the thread 16 of the gate element 15.
- the link element 15 can already be moved a certain distance by screwing in the threaded rod 27, for example to roughly secure the structure in the opening 7 of the plate 8 so that it does not fall out can.
- the tensioning element 26 is then pressed in the direction of the bevel 12 or moved relative to the rod 27 .
- the link element 15 is moved a further distance transversely to the running direction L of the strands 4 that have been inserted.
- the frame cover 2.2 is braced against the frame base 2.1 and at the same time the entire frame 2 is permanently fixed in the opening 7 of the plate 8 via the hooks 13, 14.
- the rod 27 can also be releasably connected to the gate element in a different manner.
- a hook at the end of the rod 27 would be conceivable, which can hook onto the link element 15 after the rod 27 has been inserted through a hole in the link element 15 .
- a connection by clipping, latching, by means of a bayonet lock, a rotary lock or the like is also conceivable.
- the rod 27 could also be a part of the link element 15 or be realized in one piece with it and accordingly be releasably connected to the eccentric lever 25 .
- clamping element 24 in the form of a clamping element 24 with rod 27 and eccentric lever 25, which enables the device 1 to be operated without tools
- other clamping elements 24 would also be conceivable, which could be operated with or without tools, for example lever clamps, toggle clamps, turnbuckles or the like.
