Description
Vorrichtung zur Befestigung einer Filterscheibe an Einern Frontrahmen eines FernsehempfangsgerätesDevice for attaching a filter disc to a front frame of a television receiver
Die Neuerung betrifft eine Vorrichtung zum Befestigen einer Filterscheibe an einem Frontrahmen eines Fernsehempfangsgerätes .The innovation relates to a device for attaching a filter disk to a front frame of a television receiver .
Eur Erhöhung des Kontrastes eines Fernsehbildes ist es bekannt, Filterscheiben vor der Bildröhre anzuordnen und diese an dem Frontrahmen mittels Spannverbinder zu befestigen. Die bekannten Filtarscheiben weisen Durchgangsbohrungen auf, in die Schrauben einsetzbar sind, welche in Gewindebohrungen in dem Frontrahmen eingeschraubt werden. Bei anderen Spannverbindern wird eine exne Schnellverschlußschraube in Form eines Drehknebelverschlusses in eine entsprechende Durchgangsöffnung in der Filterscheibe und in eine kongruente in dem Frontrahnien eingesetzt.It is an increase in the contrast of a television picture known to arrange filter disks in front of the picture tube and these to the front frame by means of tension connectors attach. The known filter disks have through holes into which screws can be inserted, which are screwed into threaded holes in the front frame. With other tension connectors a exne quick release screw in the form of a rotary toggle fastener into a corresponding passage opening in the filter disc and into a congruent one in the Front framing used.
Der Neuerung liegt die Aufgabe zugrunde/ einen Spannverbinder in Form eines Drehknebelverschlusses so auszubilden und an einer Stelle am Frontrahmen vorzusehen, daß ein sicherer Halt der Filterscheibe gewährleistet ist, ohne daß in dieser Durchgangsöffnungen vorgesehen werden müssen. Außerdem soll gewährleistet sein, daß die Befestigungsöffnungen in dem Frontrahmen auch bei abgenommener Filterscheibe nicht dominierend hervortreten.The innovation is based on the task / a tension connector in the form of a rotary toggle fastener to be designed and provided at one point on the front frame that a secure hold of the filter disc is guaranteed without having to provide through openings in this. Also should be guaranteed that the mounting openings in the front frame even with the filter screen removed do not emerge dominantly.
Die Aufgabe wird neuerungsgemäß nach der im Anspruch 1 wiedergegebenen technischen Lehre gelöst.According to the innovation, the object is achieved according to the claim 1 reproduced technical teaching solved.
Vorteilhafte Weiterbildungen der Neuerung sind Gegenstand der Unteransprüche.Advantageous further developments of the innovation are the subject of the subclaims.
Durch die Verlagerung des Befestigungspunktes des Drehknebelspannverbinders in die diagonale Verlängerung zu der Filterscheibe is;t es möglich, ohne Durchgangsbohrungen in der Filterscheibe diese zu befestigen. Ferner ist ein leichtes Entfernen der Filterscheibe gewährleistet, ebenso ein leichtes nachträgliches Anbringen derselben.By moving the fastening point of the rotary toggle clamp connector into the diagonal extension to the filter disc, it is possible to close the filter disc without through-holes attach. Furthermore, easy removal of the filter disk is ensured, as is easy subsequent attachment of the same.
Die Neuerung wird nachfolgend anhand des in den Fig. 1 und 2 dargestellten Ausführungsbeispiels näher erläutert.The innovation is explained in more detail below with reference to the exemplary embodiment shown in FIGS. 1 and 2 explained.
Auf den Frontrahmen 1 eines Fernsehempfangsgerätes ist eine Filterscheibe 2 aufgelegt. Entlang den Seitenkanten der Filterscheibe sind im Ausführungsbeispiel Nuten 3 in dem Frontrahmen eingearbeitet. In diagonaler Verlängerung der Scheibenecken ist eine Durchgangsbohrung 4 vorgesehen, in die jeweils zwei in die Nuten eingeschnittene Langlöcher 5 und 6 einmünden. In die so gebildete Durchgangsöffnung kann der neuerungsgemäß ausgebildete Drehknebelspannverbinder 7, der aus einem Bolzen 8 mit einem Zapfen 9, der am unteren Ende angesetzt ist, besteht, eingefügt werden. Das Oberteil des Drehknebelspannverbinders 7 besteht aus einer nahezu quadratisch ausgebildeten Druckplatte 10, in deren einer Ecke der Bolzen 8 befestigt ist. Zweckmäßigerweise ist der Zapfen 9 in diagonaler Richtung der Druckplatte 10 angeordnet. Dies ist aber nicht unbedingt notwendig. Der Zwischenraum zwischen der Druckplatte 10 und dem Zapfen 9 ist so bemessen, daß beim üntergreifen der Frontrahmenwandung eineA filter disk 2 is placed on the front frame 1 of a television receiver. Along the side edges of the filter disk, grooves 3 are incorporated in the front frame in the exemplary embodiment. In diagonal Extension of the disc corners is provided with a through hole 4, in each of which two in the grooves incised elongated holes 5 and 6 open. According to the innovation, the through opening formed in this way can be inserted into the through opening trained rotary toggle connector 7, which consists of a bolt 8 with a pin 9, which is attached to the lower end is, consists, to be inserted. The upper part of the rotary toggle clamp connector 7 consists of a almost square shaped pressure plate 10, in one corner of which the bolt 8 is attached. Appropriately the pin 9 is arranged in the diagonal direction of the pressure plate 10. But this is not the case indispensable. The space between the pressure plate 10 and the pin 9 is dimensioned so that when reaching under the front frame wall a
Druckkraft auf die Oberfläche der Filterscheibe 2 ausgeübt wird. Der Drehknebelspannverbinder wird mit dem Bolzen 8 und dem Zapfen 9 in die entsprechende Öffnung eingesetzt und durch Drehen/ wie aus Fig. 2 ersichtlich, in die Verriegelungsposition geschwenkt. Dabei greift die Druckfläche des Zapfens 9 unter diePressure force is exerted on the surface of the filter disc 2. The rotary toggle connector comes with the bolt 8 and the pin 9 are inserted into the corresponding opening and by turning / as in FIG. 2 can be seen pivoted into the locking position. The pressure surface of the pin 9 engages under the
