Description

Die Erfindung betrifft eine Vorrichtung zur neigbaren Lagerung einer Lautsprecherbox auf einer Stange, gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device for tiltably mounting a loudspeaker box on a rod, according to the preamble of claim 1.

Eine derartige Vorrichtung ist aus der DE 203 16 984 U1 bekannt.Such a device is known from DE 203 16 984 U1 known.

Lautsprecherboxen werden bei musikalischen Darbietungen, insbesondere bei vielen Zuhörern, oft auf Stativen erhöht angeordnet, so dass der Schall über die Köpfe der Zuhörer hinweg abgestrahlt wird. Dazu wird die Lautsprecherbox mit Hilfe einer geeigneten Aufnahmevorrichtung auf eine Stange bzw. ein Rohr des Stativs aufgesetzt. Häufig ist jedoch eine Neigung der Lautsprecherbox gewünscht, wozu eine geeignete Vorrichtung zur neigbaren Lagerung an einer Lautsprecherbox erforderlich ist.Loudspeakers are often elevated on tripods during musical performances, especially among many listeners, so that the sound is radiated over the listeners' heads. For this purpose, the speaker is placed on a rod or a tube of the tripod with the aid of a suitable receiving device. Frequently, however, an inclination of the speaker is desired, including a suitable device for tiltable storage on a speaker is required.

Durch DE 200 10 582 U1 ist ein Lautsprechersystem bekannt geworden, bei dem zur Befestigung des Lautsprechergehäuses an einer Stange in der Bodenwand des Lautsprechergehäuses mindestens zwei Aufnahmen für das obere Ende der Stange mit voneinander verschiedenen Neigungswinkeln vorgesehen sind. Dadurch ist jedoch die Anzahl der Neigungswinkel auf wenige Winkel beschränkt.By DE 200 10 582 U1 a speaker system has become known in which are provided for fixing the speaker housing to a rod in the bottom wall of the speaker housing at least two receptacles for the upper end of the rod with mutually different angles of inclination. As a result, however, the number of inclination angles is limited to a few angles.

EP 0 022 759 zeigt eine Konsole zur neigbaren Lagerung einer Lautsprecherbox. Eine Anbringung der Anordnung auf einer Stange ist jedoch nicht möglich und der Neigungswinkels lässt sich nicht leicht und problemlos ändern, da die Konstruktion bei jeder derartigen Änderung ein Lösen und Wiederbefestigen von Sicherungselementen (Flügelmuttern) erfordert, um Stabilität des Systems zu gewährleisten. EP 0 022 759 shows a console for tiltable mounting a speaker. Attachment of the assembly to a pole is not possible, however, and the angle of inclination is not easily and easily changed since the design requires loosening and reassembly of securing elements (wing nuts) to ensure stability of the system in any such change.

Aufgabe der vorliegenden Erfindung ist es, eine Neigung der Lautsprecherbox mit einer Vielzahl von Winkelstellungen zu ermöglichen, also eine feine Abstufung eines relativ großen Verstellbereichs.Object of the present invention is to tilt the speaker with a variety of angular positions allow, so a fine gradation of a relatively large adjustment.

Diese Aufgabe wird erfindungsgemäße dadurch gelöst,

  • dass eine zur Aufnahme eines Endbereichs der Stange ausgebildete Hülse mit einem geschlossenen Kopfteil versehen ist,
  • dass ein zur Befestigung an der Lautsprecherbox ausgebildetes Aufnahmeteil eine längliche als Führung für die Hülse ausgebildete Öffnung und von der Öffnung beabstandet ein Lager aufweist, in dem die Hülse mit dem Kopfteil schwenkbar gelagert ist und
  • dass im Bereich der Öffnung mindestens eine Rastvorrichtung für die Hülse vorgesehen ist.
This object is achieved according to the invention,
  • in that a sleeve designed to receive an end region of the rod is provided with a closed head part,
  • in that a receiving part designed to be fastened to the loudspeaker box has an elongate opening formed as a guide for the sleeve and spaced apart from the opening, in which the sleeve is pivotally mounted with the head part and
  • that at least one locking device for the sleeve is provided in the region of the opening.

Die erfindungsgemäße Vorrichtung hat gegenüber dem bekannten Lautsprechersystem ferner den Vorteil, dass die Lautsprecherbox zu einer Änderung des Neigungswinkels nicht von der Stange abgehoben werden muss. Es ist lediglich eine Entlastung erforderlich, wobei nach der Änderung des Neigungswinkels kein wiederholtes Aufstecken auf die Stange erforderlich ist.The device according to the invention also has the advantage over the known loudspeaker system that the loudspeaker box does not have to be lifted off the bar to change the angle of inclination. It is only a relief required, after the change of the angle of inclination no repeated attachment to the rod is required.

Je nach Ausbildung der Rastvorrichtung im Einzelnen ist eine feine Abstufung des Neigungswinkels möglich. Die erfindungsgemäße Vorrichtung hat ferner den Vorteil, dass der Drehpunkt im Inneren des Lautsprechers liegt, was einer Kippneigung der Lautsprecherbox bei stärker werdender Neigung entgegenwirkt. Außerdem sind keine wesentlich über das Gehäuse der Lautsprecherbox hinausstehenden Teile erforderlich, was bei häufigem Transport der Lautsprecherbox vorteilhaft ist.Depending on the design of the locking device in detail, a fine gradation of the angle of inclination is possible. The device according to the invention also has the advantage that the pivot point is located inside the loudspeaker, which counteracts a tilting tendency of the loudspeaker box when the inclination increases. In addition, no essential parts beyond the housing of the speaker are required parts, which is advantageous for frequent transport of the speaker.

Eine vorteilhafte Ausgestaltung der erfindungsgemäßen Vorrichtung besteht darin, dass zwischen dem Lager und dem Kopfteil ein elastisches Element wirksam und derart ausgelegt ist, dass bei der Belastung des Aufnahmeteils mit der Lautsprecherbox die Rastvorrichtung wirksam wird. Dabei ist vorzugsweise vorgesehen, dass die Rastvorrichtung von zwei parallel zu den Längsseiten der Öffnung kreisbogenförmig verlaufenden Zahnreihen gebildet wird, welche mit Zähnen an Vorsprüngen in Wirkverbindung stehen, die seitlich aus dem offenen Endbereich der Hülse hervorstehen.An advantageous embodiment of the device according to the invention is that between the bearing and the head part, an elastic element is effective and designed such that when the loading of the receiving part with the speaker, the locking device is effective. It is preferably provided that the locking device is formed by two parallel to the longitudinal sides of the opening circular arc-extending rows of teeth, which are operatively connected to projections on projections which protrude laterally from the open end of the sleeve.

Diese Ausgestaltung zeichnet sich dadurch aus, dass keinerlei Manipulationen zur Fixierung der Lautsprecherbox in der einzustellenden Neigung erforderlich sind. Es kann also auch beispielsweise nicht vergessen werden, eine zur Fixierung vorgesehene Schraube anzuziehen.This embodiment is characterized by the fact that no manipulations are required for fixing the loudspeaker box in the inclination to be set. It can therefore not be forgotten, for example, to put on a screw provided for fixation.

Die erfindungsgemäße Vorrichtung kann auch derart ausgestaltet sein, dass die Vorsprünge in kreisbogenförmige Hinterschneidungen der Öffnung eingreifen, welche die Hülse bei fehlender Belastung durch die Lautsprecherbox halten. Mit diesen Maßnahmen wird einerseits sichergestellt, dass die Hülse ohne Belastung durch die Lautsprecherbox nicht aus dem Aufnahmeteil herausfällt. Im Übrigen können die Teile der erfindungsgemäßen Vorrichtung in einfacher Weise aus Kunststoff gespritzt werden. Durch entsprechende Anschrägungen der Vorsprünge bei genügender Elastizität der Teile kann bei der Herstellung die Hülse mit einem geeigneten Werkzeug in das Aufnahmeteil gepresst werden, so dass die Vorsprünge hinter den Hinterschneidungen verrasten.The device according to the invention can also be configured such that the projections engage in arc-shaped undercuts of the opening, which hold the sleeve in the absence of stress through the speaker. On the one hand, these measures ensure that the sleeve does not fall out of the receiving part without being stressed by the loudspeaker box. Incidentally, the parts of the device according to the invention can be injected in a simple manner of plastic. By appropriate chamfers of the projections with sufficient elasticity of the parts, the sleeve can be pressed with a suitable tool in the receiving part during manufacture, so that the projections engage behind the undercuts.

Eine weitere vorteilhafte Ausgestaltung besteht darin, dass die Hinterschneidungen durch eine Verzahnung als weitere Rastvorrichtung ausgebildet sind. Damit wird die Hülse auch bei fehlender Belastung in der einmal gewählten Stellung gehalten. Wird diese Ausgestaltung derart ausgebildet, dass die Rastpunkte der weiteren Rastvorrichtung und der Rastvorrichtung sich jeweils gegenüber stehen, hat dies den Vorteil, dass beim Aufsetzen der Lautsprecherbox auf das Stativ nach dem Loslassen des Lautsprechers die gleiche Winkelstellung eingenommen wird wie während des Aufsetzens.A further advantageous embodiment is that the undercuts are formed by a toothing as a further locking device. Thus, the sleeve is held even in the absence of stress in the once selected position. If this embodiment is designed such that the latching points of the further latching device and the latching device are in each case opposite, this has the advantage that the same angular position is assumed when placing the speaker on the tripod after releasing the speaker as during placement.

Eine besonders sichere seitliche Führung der Hülse wird bei einer Weiterbildung der Erfindung dadurch ermöglicht, dass die Hülse im Bereich des Kopfteils zwei seitlich hervorstehende Zapfen aufweist, welche in Nuten eingreifen, welche sich an gegenüberliegenden Seiten des Aufnahmeteils zwischen der Öffnung und dem Lager erstrecken.A particularly secure lateral guidance of the sleeve is made possible in a development of the invention in that the sleeve in the region of the head part has two laterally projecting pins which engage in grooves which extend on opposite sides of the receiving part between the opening and the bearing.

Zur Aufnahme der durch das Gewicht der Lautsprecherboxen auf das Gelenk wirkenden Kraft kann bei dieser Weiterbildung vorgesehen sein, dass die Hülse am Kopfteil mindestens einen halbzylinderförmigen Körper aufweist, der bei Belastung des Aufnahmeteils mit der Lautsprecherbox in mindestens einer Lagerhalbschale im Aufnahmeteil schwenkbar gelagert ist. Bei mittig angeordnetem elastischen Element ist zu beiden Seiten je ein halbzylinderförmiger Körper vorgesehen.To accommodate the force acting on the joint by the weight of the loudspeakers on the joint, it can be provided in this development that the sleeve has at least one semi-cylindrical body on the head part, which is mounted in a load-bearing manner on the receiving part with the loudspeaker box in at least one bearing half-shell in the receiving part. When centrally arranged elastic element is provided on both sides depending on a semi-cylindrical body.

Eine einfache Montagemöglichkeit des Aufnahmeteils an der Lautsprecherbox ist dadurch gegeben, dass das Aufnahmeteil mit einem die Öffnung umschließenden Flansch zur Befestigung an der Lautsprecherbox versehen ist.A simple mounting option of the receiving part of the speaker is given by the fact that the receiving part is provided with a flange surrounding the opening for attachment to the speaker.

Die Stange bzw. das Rohr des Stativs wird beim Aufsetzen des Lautsprechers in die Hülse 1 bis zum Anschlag 4 eingeschoben. Im Kopfteil 3 befindet sich eine Aussparung 5 zur Aufnahme eines federnden Elementes, das - wie in Fig. 1 dargestellt - durch einen Gummikörper 6 oder durch eine geeignete Feder gebildet werden kann.The in the Figures 1 and 2 illustrated sleeve 1 consists of a hollow cylindrical part 2, to which a hemispherical head part 3 is connected. The rod or the tube of the tripod is inserted when placing the speaker in the sleeve 1 to the stop 4. In the head part 3 is a recess 5 for receiving a resilient element, which - as in Fig. 1 represented - can be formed by a rubber body 6 or by a suitable spring.

Am offenen Ende der Hülse 1 sind in entgegengesetzter Richtung zwei Vorsprünge 7, 8 vorgesehen, die in Richtung auf das Kopfteil jeweils drei Rastzähne 9 und in entgegengesetzter Richtung einen Rastzahn 10 aufweisen. Die Öffnung der Hülse 1 ist mit einer Phase 11 versehen, um das Aufsetzen auf das Stativ zu erleichtern.At the open end of the sleeve 1, two projections 7, 8 are provided in the opposite direction, each having three locking teeth 9 and in the opposite direction a locking tooth 10 in the direction of the head part. The opening of the sleeve 1 is provided with a phase 11 to facilitate placement on the tripod.

Zur besseren Erkennbarkeit des Verlaufs des Hohlraums des Aufnahmeteils 12 wurden in Fig. 3 an sich nicht sichtbare Kanten, deren Darstellung bei der Rechner unterstützten Entwicklung derartige Teile Voraussetzung ist, belassen. Zur Befestigung des Aufnahmeteils 12 in der Lautsprecherbox ist ein Flansch 13 mit Senklöchern vorgesehen. Eine Öffnung 14 bildet zusammen mit kreisbogenförmigen Nuten 15 (nur eine davon ist in Fig. 5 sichtbar) eine Führung für die Vorsprünge 7, 8 (Fig. 1, Fig. 2) der Hülse 1. Das Kopfteil 3 der Hülse 1 bildet zusammen mit dem unteren Bereich 16 des Aufnahmeteils 12 ein Gelenk, so dass die Hülse in dem von der Öffnung 14 vorgegebenen Winkel geschwenkt werden kann. Parallel zu den Längsrändern der Öffnung 14 verlaufen kreisbogenförmig zwei Zahnreihen 16, 17.To better detect the course of the cavity of the receiving part 12 were in Fig. 3 not visible in itself Edges whose representation is a prerequisite for computer-assisted development of such parts. For fixing the receiving part 12 in the speaker a flange 13 is provided with countersunk holes. An opening 14 forms together with circular-arc grooves 15 (only one of which is in Fig. 5 visible) a guide for the projections 7, 8 ( Fig. 1, Fig. 2 ) of the sleeve 1.

Bei Belastung der Vorrichtung mit dem Gewicht der Lautsprecherbox wird das federnde Element zusammengedrückt, so dass eine Verrastung der Rastzähne 9 mit den Rastzähnen 20, 21 erfolgt. Somit wird der Neigungswinkel der Lautsprecherbox ohne weitere Manipulationen fixiert.If the device is not loaded, the resilient element 6 presses the projections 7, 8 against the upper edges 18 (undercuts) of the grooves 15, wherein the locking teeth 9 engage in corresponding recesses 19. When the device is loaded with the weight of the loudspeaker box, the resilient element is compressed, so that latching of the latching teeth 9 with the latching teeth 20, 21 takes place. Thus, the inclination angle of the speaker is fixed without further manipulation.

Bei dem in den Figuren 7 bis 10 dargestellten Ausführungsbeispiel wird eine Führung und Lagerung der Hülse 1' in dem Aufnahmeteil 12' dadurch erreicht, dass am Kopfteil 3' der Hülse 1' zwei Zapfen 24, 25 vorgesehen sind, die beim Einsetzen der Hülse 1' in das Aufnahmeteil 12' und bei der Bewegung der Hülse 1' infolge der Be- bzw. Entlastung durch die Lautsprecherbox in Nuten 26, 27 im Aufnahmeteil 12' gleiten. Dadurch wird sowohl im be- als auch im entlasteten Zustand eine sichere seitliche Führung der Hülse 1' im Bereich des Kopfteils 3' gewährleistet. Als Gelenk dienen bei dem Ausführungsbeispiel nach den Figuren 7 bis 10 zwei halbzylinderförmige Körper 28, 29, die in entsprechende Lagerhalbschalen 30, 31 im Aufnahmeteil 12' eingreifen.
