Opfindelsen vedrører et montagebeslag til brug ved montering af byggeblokke i forudbestemt dybde i et kabinet opbygget med systemhul forsynede bæreskinner, hvor montagebeslagene forbinder bæreskinnerne.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a mounting bracket for use in mounting building blocks of predetermined depth in a housing constructed with system-hollowed support rails, wherein the mounting brackets connect the support rails.

Elektriske fordelingsanlæg til industriel brug opbygges hyppigt i kabinetter, hvor strømskinner og kabler til til- og afgang er anbragt bagest (inderst) i kabinettet, og de til fordeling, afbrydning og beskyttelse beregnede komponenter er an-10 bragt nærmere de låger, som beskytter mod berøring og støv. Boltesamlinger er hyppige i traditionelle kabinetter, idet de både vandret og lodret, er opbygget med bæreskinner, hvorpå der er fastgjort montagebeslag. Et kabinet, som er opbygget af en forramme og en bagramme, kan have sådanne montagebeslag til 15 forbindelse mellem rammerne, og disse montagebeslag kan atter bære skinner mellem sig, på hvilke der enten kan være anbragt byggeblokke eller komponenter, eller der kan være anbragt bæreplader for grupper af sådanne. Som det vil være indlysende, kræver sådanne opbygninger et stort antal boltesamlinger, og 20 det er til løsning af en del af dette problem foreslået at anvende skinner med systemhuller sammen med særlige beslag dansk fremlæggelsesskrift nr. 149.904. Boltesamlinger er tidskrævende og dermed dyre at bruge ved såvel nymontage som ændringer. Især ved ændringer af styre- og beskytte!seskompo-25 nenter i takt med den løbende udvikling på området medfører boltesamlinger store afbrydelser i strømforsyningen.Electrical distribution systems for industrial use are frequently built up in enclosures where power rails and cables for entry and exit are located at the back (innermost) of the enclosure, and the components intended for distribution, disconnection and protection are placed closer to the doors which protect against touch and dust. Bolt joints are frequent in traditional enclosures in that they are built up horizontally and vertically with support rails on which mounting brackets are attached. A housing constructed of a front frame and a rear frame may have such mounting brackets for connection between the frames, and these mounting brackets may again carry rails between them, on which either building blocks or components may be mounted, or supporting plates may be mounted for groups of such. As will be obvious, such structures require a large number of bolt assemblies, and it is proposed to use rails with system holes in conjunction with special fittings Danish Patent Publication No. 149,904 to solve part of this problem. Bolt joints are time-consuming and therefore expensive to use with both new assembly and alterations. Especially with changes in control and protection components in step with the ongoing development in the field, bolt assemblies cause major interruptions in the power supply.

Det er opfindelsens formål at tilvejebringe et montagebeslag, som med hensyn til monteringstid er en forbedring i forhold 30 til hidtil kendt teknik. Dette opnås ved, at montagebeslaget ifølge opfindelsen er ejendommeligt ved, at der er udformet indklappelige møtrikker ud i ét med montagebeslagene på positioner, som svarer til almindelige byggeblokkes monteringsdybder.It is an object of the invention to provide a mounting bracket which, in terms of mounting time, is an improvement over prior art. This is achieved by the fact that the mounting bracket according to the invention is peculiar in that collapsible nuts are designed in combination with the mounting brackets at positions corresponding to the mounting depths of ordinary building blocks.

Herved opnås, at montøren hurtigt kan montere byggeblokke i en ønsket monteringsdybde uden brug af løse møtrikker, idet denThis ensures that the installer can quickly mount building blocks at a desired mounting depth without the use of loose nuts, as

2 pågældende indklappelige møtrik blot klappes ind og monteringen hertil let kan foregå ved hjælp af skruetrækkere med magnetisk klinge til fastholdelse af en bolt eller skrue, som føres i indgreb med den indklappede møtrik.2, the collapsible nut in question is simply folded in and its mounting can easily be carried out by means of screwdrivers with magnetic blade for holding a bolt or screw which is engaged with the collapsed nut.

Opfindelsen vil blive nærmere beskrevet under henvisning til tegningen, hvor fig. 1 viser to bæreskinner med et montagebeslag ifølge op-10 findelsen anbragt, fig. 2 viser den ene ende af et montagebeslag ifølge opfindelsen, hvorved især den særlige udførelse af en indgrebsklo kan ses, og 15 fig. 3 viser den ene ende af et montagebeslag med indklappet møtrik og ledekegle ifølge krav 2.The invention will be described in more detail with reference to the drawing, in which fig. 1 shows two support rails with a mounting bracket according to the invention arranged; FIG. 2 shows one end of a mounting bracket according to the invention, whereby in particular the particular embodiment of an engagement claw can be seen; and FIG. 3 shows one end of a mounting bracket with collapsed nut and guide cone according to claim 2.

I fig. 1 ses en bæreskinne 1 fra forrammen til et elektrisk 20 fordelingsanlæg udformet som et kabinet og en bæreskinne 2, som hører til bagrammen. Begge bæreskinner er opbygget som rektangulære rør med systemhuller 3 i alle kanter. Af overskuelighedsgrunde er kun de systemhuller vist, som kan benyttes med det på figuren viste montagebeslag 4 med den oriente-25 ring, som er givet på tegningen. Montagebeslaget 4 er vist overskåret med indklappelige møtrikker 5 og 5n anbragt i dybderne dl og dn fra forkanten. Brugen af beslaget er følgende:In FIG. 1 shows a support rail 1 from the front frame of an electrical distribution system designed as a housing and a support rail 2 belonging to the rear frame. Both support rails are constructed as rectangular tubes with system holes 3 on all edges. For reasons of clarity, only those system holes are shown which can be used with the mounting bracket 4 shown in the figure with the orientation given in the drawing. The mounting bracket 4 is shown cut with foldable nuts 5 and 5n located at the depths dl and dn from the leading edge. The use of the bracket is as follows:

Der benyttes altid to beslag, ét i højre og ét i venstre side af kabinettet (det på fig. 1 viste er anbragt i venstre side).Two fittings are always used, one on the right and one on the left side of the cabinet (the one shown in Fig. 1 is located on the left side).

30 Beslagene anbringes i højder, som svarer til den montageplade, som skal anbringes mellem beslagene eller således, at den hjælpebæreskinne, som skal anbringes derimellem parallelt med forrammen, bliver vandret. Dersom der benyttes montageplade, vil det være nødvendigt med fire montagebeslag. Indgrebsklø-35 erne 6 og 7 er blot flige, som er bukket vinkelret på beslagets plan, og som kan nå ind i systemhullerne. Derved er det opnået, at beslagene er ens for venstre og højre side, idet de 330 The brackets are placed at heights corresponding to the mounting plate to be placed between the brackets or so that the auxiliary support rail to be placed therebetween parallel to the front frame is horizontal. If a mounting plate is used, four mounting brackets will be required. The engagement pins 6 and 7 are merely tabs which are bent perpendicular to the plane of the bracket and which can reach into the system holes. In this way it is achieved that the fittings are the same for the left and right sides, the 3

blot kan vendes. Efter indklapning af de møtrikker, som svarer til den ønskede dybde, kan skruer gennem huller i hjælpebære-skinner eller montageplade etablere forbindelse mellem disse og montagebeslagene, hvorved udtrækning af montagebeslagene af 5 hullerne 3 umuliggøres.can only be reversed. After folding in the nuts corresponding to the desired depth, screws through holes in auxiliary support rails or mounting plate can establish a connection between these and the mounting brackets, thereby extracting the mounting brackets of the 5 holes 3.

Hvor udførelsesformen, der er vist i fig. 1, har fire ens indgrebskløer, er der i fig. 2 vist en udførelsesform, hvor de øverste kløer 6 er ens og de nederste 7 også er indbyrdes ens.Where the embodiment shown in FIG. 1, has four identical engagement claws; 2 shows an embodiment in which the upper claws 6 are the same and the lower 7 are also mutually identical.

10 I samme afbildning ville udførelsesformen, der er vist i fig.In the same view, the embodiment shown in FIG.

1 svare til kløer 7 såvel oppe som nede. Montagebeslaget vist i fig. 2 benyttes noget anderledes, idet det skal holdes skråt, således at kloerne 6 kan hægtes ind i hullerne 3 først, hvorefter de svagt krummede og derved noget fjedrende kløer 7 kan 15 presses ind i de nedenunder beliggende huller. Det er herved opnået, at montagebeslaget før den endelige montering med montageplade bliver ufølsom overfor mekaniske påvirkninger, selv sådanne, som ville forsøge at trække det ud af indgreb. En simpel modifikation er at udforme kloerne 7, så en del ved 20 fjedring går i indgreb med indersiden af bæreskinnen 1; derved vil det være nødvendigt med værktøj til presning af kloen 7 i en retning, så dette indgreb udløses, dersom det ønskes at fjerne montagebeslaget 4 fra sin position. Ligeledes i fig. 2 er vist den indklappelige møtrik 5, som bringes i korrekt po-25 sition ved indklapning om den lodrette akse 8. Der opnås ved montage en formindskelse af kraften, dersom der langs aksen 8 er sørget for svækkelse af pladetykkelsen t ved prægning eller direkte fjernelse af materiale.1 correspond to claws 7 both up and down. The mounting bracket shown in FIG. 2 is used somewhat differently in that it has to be held obliquely so that the claws 6 can be inserted into the holes 3 first, after which the slightly curved and thereby somewhat resilient claws 7 can be pressed into the holes located below. It is hereby achieved that the mounting bracket before the final mounting with the mounting plate becomes insensitive to mechanical stresses, even those which would attempt to pull it out of engagement. A simple modification is to design the claws 7 so that a portion at 20 resiliently engages the inside of the support rail 1; thereby, tools will be needed to press the claw 7 in one direction so that this engagement is triggered if it is desired to remove the mounting bracket 4 from its position. Also in FIG. 2, the collapsible nut 5 is shown, which is brought into the correct position by folding about the vertical axis 8. A reduction of the force is obtained when the plate thickness t is reduced by embossing or direct removal along the axis 8. of material.

30 I fig. 3 er vist en udførelsesform for opfindelsen, hvor en møtrik er vist i indklappet tilstand, så en ledekegle 9 formet ved prægning i pladematerialet i samme operation som udstansningen af den C-formede figur tydeligt ses. Praksis har vist, at en sådan ledekegle i høj grad simplificerer montagen af en 35 montageplade på montagebeslagene, idet det blot er nødvendigt at anbringe en skrue på en skruetrækker med magnetisk klinge eller en krydskærvsskruetrækker, hvorefter den i én operation ved drejning kan monteres og spændes.In FIG. 3, an embodiment of the invention is shown in which a nut is shown in the folded state, so that a guide cone 9 formed by embossing in the sheet material in the same operation as the punching of the C-shaped figure is clearly seen. Practice has shown that such a guide cone greatly simplifies the mounting of a mounting plate on the mounting brackets, since it is only necessary to apply a screw to a screwdriver with magnetic blade or a cross-screwdriver, whereupon it can be mounted and tightened in one operation. .
