Description
Die Erfindung bezieht sich auf eine Rohrschelle zum Befestigen von Hängescheinwerfern.The The invention relates to a pipe clamp for attaching suspended projectiles.
Bei
einer aus DIN 15560 Teil 25, Bild 10 bekannten Rohrschelle zum Befestigen
von Hängescheinwerfern
ist ein etwa C-förmiger
Tragbügel
vorgesehen, dessen oberer, gekrümmter
Abschnitt zum Einhängen
an einem Tragrohr oder einem Gitterstab eines Gittemägers vorgesehen
ist. Der untere, etwa horizontale Abschnitt des Tragbügels ist
mit einer Hülse
verbunden, in welche ein Befestigungszapfen des Hängescheinwerfers
eingesteckt und mittels einer Feststellschraube arretiert wird.
An dem vertikalen Abschnitt des Tragbügels ist ein einarmiger Schließhebel gelenkig
befestigt, dessen gekrümmte Vorderseite
zur zangenartigen Anlage gegen das Tragrohr bzw. den Gitterstab
bewegt werden kann mit Hilfe einer Feststellschraube, die eine Schraubbohrung
des Tragbügels
durchsetzt und an einem nockenartigen Vorsprung auf der Rückseite
des Schließhebels
angreift. Eine ähnliche
Konstruktion für
eine Rohrschelle zum Befestigen von Hängescheinwerfern ist auch aus
der
Die Montage der vorstehend genannten Rohrschellen nach dem Stand der Technik erfordert eine Bedienung mit beiden Händen, da der Schließhebel nach Entfernen der Feststellschraube manuell in seine Offenstellung bewegt werden muss, bevor der Tragbügel mit seinem oberen, gekrümmten Abschnitt von dem Tragrohr oder Traggitter abgenommen werden kann. Ein weiterer Nachteil der bekannten Rohrschellen ist der Aufbau des Tragbügels aus parallelen Platten, welche durch Stege miteinander verbunden sind. Der Schließbügel bewegt sich dabei in dem Raum zwischen den parallelen Platten. Infolge dieses plattenförmigen Aufbaus besitzt der Tragbügel an seinem oberen, gekrümmten Abschnitt eine relativ geringe Auflagefläche auf dem Tragrohr oder Traggitter. Bei höheren Traglasten oder bei zu großer Klemmung des Schließhebels besteht die Gefahr, dass das Tragrohr oder Traggitter durch zu hohe Flächenpressungen beschädigt wird.The Assembly of the above-mentioned pipe clamps according to the prior Technique requires operation with both hands, as the lock lever after Remove the locking screw manually moved to its open position must be before the mounting bracket with its upper, curved Section can be removed from the support tube or support grid. Another disadvantage of the known pipe clamps is the structure of the carrying handle from parallel plates, which are interconnected by webs are. The striker moves doing so in the space between the parallel plates. As a result this plate-shaped Construction has the mounting bracket at its upper, curved Section a relatively small contact surface on the support tube or support grid. At higher Payloads or too big clamping of the closing lever there is a risk that the support tube or support grid by too high surface pressures damaged becomes.
Aus
der
Die Aufgabe der Erfindung besteht demgegenüber darin, bei einer Rohrschelle der eingangs erwähnten Art eine Montage mit nur einer Hand zu ermöglichen. Ferner wird angestrebt, Beschädigungen des Tragrohrs oder Traggitters mit Sicherheit zu verhindern.The The object of the invention is in contrast, in a pipe clamp the aforementioned Type to allow assembly with one hand. It is also sought Damage to the To prevent support tube or support grid with security.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.These The object is achieved by the characterizing features of claim 1 solved.
Vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Rohrschelle ergeben sich aus den Unteransprüchen.advantageous Embodiments and developments of the pipe clamp according to the invention emerge from the dependent claims.
