Beschreibung:Description:

Die Neuerung bezieht sich auf einen Abdeckrahmen für Lautsprecherboxen mit Stoffbespannung.The innovation relates to a cover frame for loudspeaker boxes with fabric covering.

Es sind Winkelrahmen für diese Zwecke aus Kunststoff-, Blech- und Holzprofilen bekannt, welche zur Lautsprecherabdeckung mit Stoff bespannt sind. Abhängig von Materialstärke und Abgrenzfläche dieser Winkelrahmen ergeben sich meßbare Reflexe und Irritationen im Ton an diesen Abstrahlflächen, welche unerwünscht sind. Andererseits benötigt man vorallem für größere Lautsprecherboxen entsprechende Randprofile, um eine genügende Stabilität zu erhalten.There are angle frames for these purposes made of plastic, sheet metal and wood profiles known, which are covered with fabric to cover the loudspeakers. Depending on the material thickness and the interface This angular frame results in measurable reflections and irritations in the sound on these radiating surfaces, which are undesirable. on the other hand you need appropriate edge profiles especially for larger loudspeaker boxes in order to obtain sufficient stability.

Aufgabe der Neurung ist es einen Abdeckrahmen für Lautsprecherboxen mit Stoffbespannung zu schaffen, bei welchen keine solche Reflexe und Irritationen auftreten.The task of the innovation is a cover frame for loudspeaker boxes to create with fabric covering, in which no such Reflexes and irritations occur.

Der Abdeckrahmen für Lautsprecherboxen mit Stoffbespannung kennzeichnet sich gemäß der Neuerung hierzu durch einen vorzugsweise abgeflachten Winkelrahmen bestehend aus gelochten (Blech-) Streife: insbes. mit lochfreien Rändern, über welche die Bespannung läuft. Hierdurch wird eine randseitige Abstrahlfläche für de.n Ton vermieden. The cover frame for loudspeaker boxes with fabric covers indicates According to the innovation, a preferably flattened angle frame consisting of perforated (sheet metal) strips: especially with perforated edges over which the covering runs. This avoids an edge-side radiation surface for the tone.

Eine bevorzugte Ausbildung eines Abdeckrahmens gemäß der NeuerungA preferred embodiment of a cover frame according to the innovation

ist beispielsweise in der Zeichnung dargestellt sowie nachfolgend beschrieben und zwar zeigen:is shown for example in the drawing and described below, namely show:

F i g . 1 einen pespecktivischen Einblick in einen Winkelrahmen mit Stoffbespannung undF i g. 1 a pespectivic view of an angled frame with fabric covering and

F i g . 2 einen Querschnitt durch diesen Winkelrahmen.F i g. 2 shows a cross section through this angle frame.

Wie aus der Zeichnung ersichtlich ist, wird der Abde<-krahm<=n durch einen abgeflachten Winkel aus einem gelochten Blechstreifen 1 gebildet mit lochfreien Rändern 2 und 3 über welche die Stoffbespannung 5 läuft. Hierbei stehen die lochfreien, beidseitigen, schmalen Ränder 2,3 rechtwinklig zueinander, wie dies aus Fig. 2 ersichtlich wird, und die unter 135° zur Bildung des Winkelrahmens dazwischenliegende breitere Abflachung 1 ist feingelocht, sogen, deutsche Lochung.As can be seen from the drawing, the Abde <-krahm <= n formed by a flattened angle from a perforated sheet metal strip 1 with perforated edges 2 and 3 over which the Fabric covering 5 is running. The hole-free, double-sided, narrow edges 2,3 at right angles to each other, as can be seen from Fig. 2, and the under 135 ° to form the angular frame The wider flat area 1 in between is finely perforated, so-called German perforation.

Schließlich ist, wie dies vorallem aus Fig. 1 ersichtlich wird, der abgeflachte Winkelrahmen 1-3 mit innenseitig über Eck verlaufenden Blechbändern 4,6 zur Versteifung ausgerüstet, welche gleichzeitig zur Befestigung am Lautsprechergehäuse dienen, z.B. mittels Steck- oder Schraubbolzenverbindung, wie dies hier nicht besonders dargestellt ist.Finally, as can be seen above all from FIG. 1, the flattened angle frame 1-3 with the corner frame on the inside Sheet metal bands 4.6 equipped for stiffening, which also serve to attach to the loudspeaker housing, e.g. by means of a plug or screw bolt connection, as is not particularly shown here.
