Abstract

Überkopftor (1) mit einer Gewichtsausgleichseinrichtung unter Verwendung von Schraubenzugfedern (14), die zwischen einem Seiten­ holm (4) der Zarge (3) und einem Schwenkhebel (5) angeordnet sind, der seinerseits an der Zarge drehbar gelagert und an dem Torblatt angelenkt ist, das im übrigen in horizontalen Führungsschie­ nen über Rollen (10) verschiebbar gelagert ist. Zum Zwecke der Sicherung vor abgeschleuderten Federteilen bei Federbruch sind diese Federn von ein- oder zweiteiligen Schutzelementen (18) durchgriffen, und zwar derart, daß eine formschlüssige Ver­ bindung des Schutzelements entsteht. Overhead gate (1) with a weight compensation device under Use of coil springs (14) between one side spar (4) of the frame (3) and a pivot lever (5) are arranged, the in turn rotatably mounted on the frame and on the door leaf is articulated, the rest in horizontal guide rail NEN is slidably mounted on rollers (10). For the purpose of Protection against spring parts thrown off if the spring breaks are these springs of one or two-part protective elements (18) penetrated, in such a way that a positive Ver bond of the protective element arises.
