Abstract

1. A rectangular lamp frame consisting of two transverse and two longitudinal walls (1, 1') which have an identical profile with an essentially C-shaped cross-section and edge strips (14, 15) which are inwardly bent and which together with the inner side of a transverse of longitudinal wall, as the case may be, form guide grooves (11, 12), which have opening angles (alpha, beta) of less than 90 degrees measured in relation to a straight reference line (G) passing through the openings of the guide grooves, with corner connectors (2) for connecting the longitudinal and transverse walls (1, 1') to coupling walls (21, 22) which run at right angles to one another and which are inserted into the guide grooves (11, 12) of the longitudinal and transverse walls (1, 1') by means of their upper and lower edge strips (221, 222), characterised in that each corner connector is an integral, angularly rigid, shaped part, and which has a stop rib (20) which projects at the outer side of the shaped part, which makes an angle of 45 degrees with each coupling wall (21, 22), and against which abut the dividing surfaces (10, 10') of adjacent longitudinal and transverse walls, which are cut at 45 degrees ; and that from the end regions of each longitudinal or transverse wall, respective connecting lugs (13, 13') project into the underlying coupling wall (21, 22) of the corner connector (2).

Description

Die Erfindung betrifft einen rechteckigen Leuchtenrahmen gemäss Oberbegriff von Anspruch 1.The invention relates to a rectangular lamp frame according to the preamble of claim 1.

Ein derartiger, aus der DE-A-1589253 bekannter Leuchtenrahmen besteht aus zwei identischen Längs- und zwei identischen Querwänden mit gleichem Querschnitt; vorzugsweise sind diese Teile mit 45°-Schnitten von einem Strangpressprofil abgetrennt.Such a lamp frame known from DE-A-1589253 consists of two identical longitudinal and two identical transverse walls with the same cross-section; these parts are preferably separated from an extruded profile with 45 ° cuts.

Längs- und Querwände sind an jeder Ecke mit Hilfe eines Eckverbinders zusammengehalten, zu dem zwei Winkelbleche gehören, die in entsprechende Führungsnuten der Längs- und Querwände eingesteckt sind. Eines dieser Winkelbleche verläuft parallel zu den nach aussen gekehrten Längs- und Querwänden und das andere in einer quer dazu verlaufenden Ebene; da das zuletzt genannte für die Winkelsteifigkeit verantwortlich ist, muss es eine entsprechende Breite haben, so dass auch der Rahmen in der Horizontalebene eine entsprechend grosse Breite aufweisen muss.Longitudinal and transverse walls are held together at each corner with the aid of a corner connector, to which two angle plates belong, which are inserted into corresponding guide grooves in the longitudinal and transverse walls. One of these angle plates runs parallel to the longitudinal and transverse walls facing outwards and the other in a plane running transversely to it; since the latter is responsible for the angular rigidity, it must have a corresponding width, so that the frame must also have a correspondingly large width in the horizontal plane.

Der Erfindung liegt die Aufgabe zugrunde, eine einfache Verbindung der Quer- und Längswände eines Leuchtenrahmens mit geringer horizontaler Tiefe zu schaffen, wobei die Ecken fugen- und stossfrei sein sollen.The invention has for its object to provide a simple connection of the transverse and longitudinal walls of a lamp frame with a small horizontal depth, the corners should be free of joints and joints.

Die erfindungsgemässe Lösung dieser Aufgabe ist bei einem Leuchtenrahmen der eingangs genannten Art durch die im Anspruch 1 angegebenen Merkmale gekennzeichnet.The inventive solution to this problem is characterized in a luminaire frame of the type mentioned by the features specified in claim 1.

Von besonderer Bedeutung bei der Erfindung ist die Anschlagrippe jedes Eckverbinders, die nach aussen absteht und unter 45°, bezogen auf die beiden Kupplungswände, verläuft: Durch diese Anschlagrippe, die zwischen benachbarten Längs- und Querwänden liegt, sind deren Endpositionen eindeutig definiert. Ohne eine derartige Anschlagrippe würde dagegen die Position der einen Wand beim Einschieben der anderen infolge der aufeinandergleitenden, unter 45° verlaufenden Trennflächen verändert werden. Im ungünstigsten Falle könnte dabei die Eckkante der einen Wand um einen der Wandstärke der anderen Wandung entsprechenden Betrag über die Kante der anderen Wandung hinausragen.Of particular importance in the invention is the stop rib of each corner connector, which protrudes outwards and runs at 45 °, in relation to the two coupling walls: this stop rib, which lies between adjacent longitudinal and transverse walls, clearly defines their end positions. Without such a stop rib, on the other hand, the position of one wall would be changed when the other was pushed in as a result of the separating surfaces sliding on one another at 45 °. In the worst case, the corner edge of one wall could protrude beyond the edge of the other wall by an amount corresponding to the wall thickness of the other wall.

Die Verbindung der Längs- und Querwände durch Zusammenstecken ist so einfach, dass sie vom Endverbraucher vorgenommen werden kann; das gilt zumindest für diejenige Ausführungsform, bei der Verbindungslappen der Wandungen in entsprechende Ausnehmungen in den Eckverbindern einschnappen und die Teile so gegen ein Auseinanderziehen sichern. Vorteilhaft ist es jedoch, Eckverbinder ohne Ausnehmungen zu verwenden und die Verbindungslappen der Wandungen mit entsprechendem Druck in das Material des Eckverbinders einzudrücken: In diesem Fall lassen sich Spalte an den Ecken auch bei grossen Toleranzen vermeiden.The connection of the longitudinal and transverse walls by plugging them together is so simple that it can be done by the end user; this applies at least to the embodiment in which the connecting tabs of the walls snap into corresponding recesses in the corner connectors and thus secure the parts against pulling apart. However, it is advantageous to use corner connectors without recesses and to press the connecting tabs of the walls with appropriate pressure into the material of the corner connector: In this case, gaps at the corners can be avoided even with large tolerances.

Die Erfindung wird anhand eines in den Figuren dargestellten Ausführungsbeispieles näher erläutert; es zeigen

  • Fig. 1 einen Eckverbinder in Draufsicht (Pfeilrichtung in Fig. 2),
  • Fig. 2 eine Seitenansicht des Eckverbinders gesehen in Richtung des Pfeiles II in Fig. 1,
  • Fig. eine Draufsicht entsprechend Fig. 1 auf einen Eckverbinder mit daraufgesteckten, abgeschnittenen Längs- und Querwänden,
  • Fig. 4 einen Schnitt entlang Linie IV-IV in Fig. 3 und
  • Fig. 5 eine vergrösserte Darstellung des Bereiches V in Fig. 4.
The invention is explained in more detail using an exemplary embodiment shown in the figures; show it
  • 1 is a corner connector in plan view (arrow direction in Fig. 2),
  • 2 is a side view of the corner connector seen in the direction of arrow II in Fig. 1,
  • 1 is a plan view corresponding to FIG. 1 on a corner connector with cut, cut longitudinal and transverse walls,
  • Fig. 4 is a section along line IV-IV in Fig. 3 and
  • 5 is an enlarged view of area V in FIG. 4.

Der aus Kunststoff bestehende Eckverbinder 2 hat zwei rechtwinklig zueinander verlaufende Kupplungswände 21, 22 mit oberen Randstreifen 211, 221 und unteren Randstreifen 212, 222. Im Eckbereich, wo die beiden Kupplungswände 21, 22 aufeinandertreffen, verläuft unter 45° - bezogen auf jede der beiden Kupplungswände - eine Anschlagrippe 20, deren Aussenkante denselben Verlauf hat wie die Aussenflächen der zu verbindenden Längs- und Querwände, mit denen sie bündig abschliesst. Ferner sind auf der Aussenseite jeder Kupplungswand Aussparungen 210, 220 und im unteren Randbereich auf der Innenseite Druckleisten 213, 223 angeordnet.The plastic corner connector 2 has two mutually perpendicular coupling walls 21, 22 with upper edge strips 211, 221 and lower edge strips 212, 222. In the corner area, where the two coupling walls 21, 22 meet, runs at 45 ° - in relation to each of the two Coupling walls - a stop rib 20, the outer edge of which has the same course as the outer surfaces of the longitudinal and transverse walls to be connected, with which it ends flush. Furthermore, recesses 210, 220 are arranged on the outside of each coupling wall and pressure strips 213, 223 are arranged on the inside in the lower edge region.

Längswand 1 und Querwand 1' (Fig. 3) sind Abschnitte eines identischen Profiles mit im wesentlichen C-förmigem Querschnitt und nach innen umgelegten Randstreifen 14, 15, die mit der Innenseite der Quer- bzw. Längswand je eine Führungsnut 11, 12 bilden, die einen Öffnungswinkel a, ß kleiner 90° gegen eine durch die Öffnungen der Führungsnuten 11, 12 gelegte Bezugsgerade G aufweist; vorzugsweise werden diese Öffnungswinkel möglichst klein gewählt.Longitudinal wall 1 and transverse wall 1 '(FIG. 3) are sections of an identical profile with an essentially C-shaped cross section and inwardly folded edge strips 14, 15 which each form a guide groove 11, 12 with the inside of the transverse or longitudinal wall, which has an opening angle α, β of less than 90 ° against a reference line G through the openings of the guide grooves 11, 12; these opening angles are preferably chosen to be as small as possible.

Die Form der Kupplungswände 21, 22 des Eckverbinders entspricht hier genau dem Verlauf des Profiles von Längs- und Querwandung, so dass diese Längs- und Querwandungen - wie in Fig. 4 dargestellt - satt auf der Aussenfläche der Kupplungswände 21,22 aufliegen. Die Randstreifen 14, 15 der Kupplungswände stecken dabei in den Führungsnuten 11 und 12. Eventuelle Toleranzen werden durch die Druckleisten 213, 223 ausgeglichen, die sich beim Zusammenstecken von Quer-und Längswandungen einerseits und Eckverbinder andererseits verformen.The shape of the coupling walls 21, 22 of the corner connector corresponds exactly to the profile of the longitudinal and transverse walls, so that these longitudinal and transverse walls - as shown in FIG. 4 - rest snugly on the outer surface of the coupling walls 21, 22. The edge strips 14, 15 of the coupling walls are inserted in the guide grooves 11 and 12. Any tolerances are compensated for by the pressure strips 213, 223, which deform on the one hand and the corner connectors on the other when the transverse and longitudinal walls are put together.

Die in Fig. 3 dargestellte Endlage der Längs-und Querwände 1, 1', bezoger. auf den Eckverbinder 2 und seine Anschlagrippe 20, ist durch die in Aussparungen 210, 220 des Eckverbinders einschnappenden Verbindungslappen 13, '3' gesichert.The end position of the longitudinal and transverse walls 1, 1 'shown in FIG. on the corner connector 2 and its stop rib 20, is secured by the connecting tabs 13, '3' which snap into recesses 210, 220 of the corner connector.
