Scharnierter Schachtdeckel mit ÖffnungshilfeHinged manhole cover with opening aid

Die Neuerung betrifft Schachtdeckel, die in Scharnieren aufklappbar gelagert sind und eine Öffnungshilfe in Form einer beim Schließen eine Kraft in Öffnungsrichtung speichernden Feder aufweisen. Die Feder ist vorzugsweise als sog. Gasdruckfeder ausgebildet, wie sie zB bei Kofferraumdeckeln oder Heckklappen von PKW eingesetzt werden.The innovation concerns manhole covers that are hinged and have an opening aid in the form of a spring that stores a force in the opening direction when closed. The spring is preferably designed as a so-called gas pressure spring, such as those used in trunk lids or tailgates of cars.

Bei Schachtdeckeln besteht die Schwierigkeit, die das öffnen unterstützende Speicherkraft richtig einzustellen. Ist sie falsch eingestellt, dann ist die Kraft entweder zu klein, so daß der Deckel mit zu hohem Kraftaufwand hochgeklappt werden muß, oder zu groß mit der Folge, daß sich der Deckel nur mit Druck schließen läßt. Durch häufiges öffnen kann die Kraft naachlassen.With manhole covers, it is difficult to correctly set the storage force that supports opening. If it is set incorrectly, the force is either too small, meaning that the cover has to be folded up with too much force, or too large, meaning that the cover can only be closed with pressure. The force can decrease if the cover is opened frequently.

Der Wunsch, die Öffnungshilfekraft richtig einstellen und auch nachjustieren zu können, wird neuerungsgemäß dadurch erfüllt, daß mindestens eines der Lager, in denen die Öffnungshilfe angelenkt ist, etwa in Richtung des Wirksamw er-The desire to be able to correctly set and also readjust the opening aid force is now fulfilled by the fact that at least one of the bearings in which the opening aid is hinged is positioned approximately in the direction of the effective force.

dens der Kraft einstellbar ist. Konstruktiv wird diese Neuerung durch eine Gabel, in der der Lagerbolzen gelagert ist, und durch eine mit der Gabel verbundene Gewindestange verwirklicht, die ihr Gegenlager in einem Bock hat. Als Verstelleinrichtung fungieren*Mutter und Kontermutter auf der Gewindestange. Um die Gabel und die Gewindestange vor Biegekräften zu bewahren, wird in Ausgestaltung der vorbeschriebenen Konstruktion vorgeschlagen, den Lagerbolzen beidseitig über die Gabelteile zu verlängern und dort in Richtung der Gewindestange verlaufenden Längsschlitzen zu führen. Sofern die Öffnungshilfe als Schwenklager schon eine Gabel, d.h. eine Doppelöse besitzt, enthält die Gewindestange nur eine einfache Lageröse. Als Führungsteil kann auch ein mit der Gewindestange verbundener Querstab dienen. Ferner ist es denkbar, als Lager einen U-förmigen Schuh zu verwenden, der in Längsführungen verstellbar befestigt ist. Das einstellbare Lager liegt vorzugsweise an der Unterseite des Schachtdeckels, so daß es bei geöffnetem Deckel bequem verstellt werden kann.dense of the force. In terms of construction, this innovation is implemented by a fork in which the bearing bolt is mounted, and by a threaded rod connected to the fork, which has its counter bearing in a bracket. The adjustment device is a nut and lock nut on the threaded rod. In order to protect the fork and the threaded rod from bending forces, it is proposed in the design described above to extend the bearing bolt on both sides over the fork parts and to guide it there in the direction of the threaded rod through longitudinal slots. If the opening aid already has a fork as a swivel bearing, i.e. a double eyelet, the threaded rod only contains a single bearing eyelet. A crossbar connected to the threaded rod can also serve as a guide part. It is also conceivable to use a U-shaped shoe as a bearing, which is adjustably attached in longitudinal guides. The adjustable bearing is preferably located on the underside of the manhole cover so that it can be easily adjusted when the cover is open.
