Description

Die Frage der Raumersparnis und der Übersichtlichkeit hat immer mehr zur Bevorzugung der sogenannten Profilinstrumente mit rechteckiger Grund- oder Befestigungsplatte geführt. Es handelt sich häufig darum, eine größere Anzahl solcher Profilinstrumente unmittelbar nebeneinander oder untereinander anzuordnen, wobei wegen des unmittelbaren Vergleichs der Zeigerausschlage benachbarter Instrumente die Zwischenräume zwischen den einzelnen Instrumenten möglichst ganz vermieden werden sollen. Es ist andererseits aus Gründen einer rationellen Anfertigung kaum zu vermeiden, daß die Höhen der einzelnen Grundplatten . oder Frontrahmen etwas voneinander abweichen, so daß es mißlich ist, die für die Befestigung dieser Instrumente erforderlichen Bohrungen in die Schalttafel nach einer festen Schablone mit Mindestabständen vorzusehen. Es muß vielmehr ein Spielraum vorhanden sein, welcher erlaubt, die nachträglich entstehenden Lücken durch Aneinanderschieben der Instrumente auszufüllen, oder bei einem Austausch der Instrumente auf die etwas größere Platzbeanspruchung Rücksicht zu nehmen.The question of saving space and clarity has more and more to be preferred the so-called profile instruments with a rectangular base or mounting plate guided. It is often a question of a larger number of such profile instruments to be arranged directly next to one another or one below the other, with the pointer deflections due to the direct comparison neighboring instruments, the gaps between the individual instruments should be avoided as far as possible should. On the other hand, for reasons of rational production, it can hardly be avoided that the heights of the individual base plates. or front frames differ slightly from each other, so that it is inconvenient to have the necessary for fastening these instruments Drill holes in the control panel according to a fixed template with minimum clearances. Rather, there must be room to maneuver, which allows the gaps that arise subsequently to be pushed together of the instruments, or if the instruments are exchanged, the somewhat larger space requirement To be considerate.

Es kommt ferner hinzu, daß es in vielen Fällen unerwünscht ist, Instrumente, z. B. sogenannte Kesselschilder, auf diese Schalttafeln von der Rückseite aus zu befestigen, abgesehen davon, daß in diesem Falle zwei Personen notwendig wären. Sind gar zwei Reihen von Instrumenten dicht aneinandergerückt, so bleibt in der Mitte kein genügender Platz mehr für die Handhabung der Befestigungsorgane von der Rückseite aus.In addition, in many cases it is undesirable to use instruments, e.g. B. so-called boiler plates, to be attached to these control panels from the rear, apart from the fact that in this case two people would be necessary. Are actually two If rows of instruments are placed close together, there is no sufficient one in the middle More space for handling the fasteners from the rear.

Durch die Erfindung wird diesen Fordernissen Rechnung getragen. Es werden dabei Hohlschienen benutzt, wie sie zur Herstellung von Gerippen zum Zusammenbau von Sicherungen bereits bekannt sind. Derartige Schienen werden aber nicht wie in dem bekannten Fall zu Rahmen vereinigt, sondern lose, ohne besondere Befestigung und ohne daß sie untereinander λ-erbunden sein müßten, auf der Rückseite der Schalttafel angeordnet, so daß die Schienen selbst und die in ihr gelagerten Muttern oder Schraubenköpfe nachträglich verschoben werden können, um die damit befestigten Geräte auszurichten.The invention takes these requirements into account. It will while using hollow rails, as they are for the production of frameworks for assembly of backups are already known. Such rails will not be like in that known case united to a frame, but loosely, without special fastening and without that they would have to be λ-linked to one another, arranged on the back of the switchboard, so that the rails themselves and the nuts or screw heads stored in them subsequently can be moved to align the attached devices.

In der Zeichnung sind einige Ausführungsbeispiele dargestellt. Abb. 1 zeigt eine Schalttafel, in der links eine Reihe rechteckiger Meßgeräte, deren Grundplattenhöhe mit h bezeichnet ist, untereinander angeordnet sind, wenn die rechteckigen Geräte für versenkten Einbau bestimmt sind. Die Schienen S1 und s., liegen hinter der Schalttafel, ohne den Ausbruch für die in die Schalttafel versenkten Geräte zu verdecken. Für jede Meßgerätreihe ist ein Schienenpaar J1 und J2 erforderlich, wie dies Abb. 2a und 2b zeigen.Some exemplary embodiments are shown in the drawing. Fig. 1 shows a control panel in which on the left a row of rectangular measuring devices, the base plate height of which is designated by h , are arranged one below the other if the rectangular devices are intended for recessed installation. The rails S 1 and s., Are located behind the control panel without covering the cut-out for the devices sunk into the control panel. A pair of rails J 1 and J 2 is required for each row of measuring devices, as shown in Figs. 2a and 2b.

Zweckmäßig ist es, wie Abb. 3 und 4 zeigen, die Mutter m als auf oder in der Schienen verschiebbares Organ auszubilden, und zwar in Form eines Rechteckes, dessen Bewegung durch eine Blattfeder/ gehemmt wird. Die Löcher I in der Schiene sind erheblich größer als der Durchmesser der Schraube, damit die etwa durchtretende Schraube einen Spielraum findet. Desgleichen sind die Schalttafellöcher für die Befestigungsbolzen größer als der Bolzendurchmesser, damit ein Abstellen der Geräte überhaupt möglich ist.It is expedient, as shown in FIGS. 3 and 4, to design the nut m as an organ that can be displaced on or in the rails, namely in the form of a rectangle, the movement of which is inhibited by a leaf spring /. The holes I in the rail are considerably larger than the diameter of the screw, so that the screw that may pass through has room for play. Likewise, the control panel holes for the fastening bolts are larger than the bolt diameter so that the devices can be parked at all.
