Abstract: Gegenstand der Erfindung ist ein Türantrieb für eine Kraftfahrzeugtür oder Kraftfahrzeugklappe, der mit einem elektromotorischen Antrieb (2), einem dem Antrieb (2) nachgeschalteten Getriebe (3), und mit einem Kraftübertragungselement (4) ausgerüstet ist. Das Kraftübertragungselement (4) ist mit einem Flügel (1) der Kraftfahrzeugtür oder Kraftfahrzeugklappe wirkverbunden. Dabei sind ein Abtriebselement (3) des Getriebes (3) und das Kraftübertragungselement (4) durch eine Verzahnung (5, 6) mit Spielausgleich gekoppelt. Erfindungsgemäß sind das Abtriebselement (3) und/oder das Kraftübertragungselement (4) zum Spielausgleich nicht nur verschiebbar, sondern nach dem Spielausgleich dauerhaft fixierbar ausgebildet.

Abstract: Disclosed is a hopper car gate assembly including a frame configured for attachment to a hopper car body. The frame defines an opening and includes a beam, wherein the beam has a slot formed therein. A stop plate is removably attached to the beam to selectively obstruct the slot. The assembly has a door supported by the frame. A stop block is attached to the door, wherein the stop block is located on the door such that when the door is inserted into the frame the stop block is aligned with the slot. With the stop plate attached to the beam, the stop block engages with the stop plate to define an open position and prevent further movement of the door in the open direction. With the stop plate detached from the beam, the stop block passes through the slot to allow removal of the door from the frame.

Abstract: The present invention relates to a device (4) for closing a door (1 ) which is rotatably constrained to a relative anchoring structure (2) and movable between a closing position and a maximum opening position, said anchoring structure (2) being either a fixed structure or a further door. Said device (4) comprises: a first fixing element (5) fixable, in use, to the door (1 ) or to the anchoring structure (2) of the door (1 ); a second fixing element (6) fixable, in use, to the anchoring structure (2) of the door (1 ) or to the door (1 ); at least one elastic flexible element (11 ) which performs, due to its configuration, an elastic function when it is subjected to bending; fixing means (12) by which said at least one elastic flexible element (11 ) is fixed to said second fixing element (6); and engaging means (14) by which said at least one elastic flexible element (11 ) remains engaged to said first fixing element (5) during the relative motion between said first (5) and said second fixing element (6), which is caused by said door (1 ) moving between said closing position and said maximum opening position and between said maximum opening position and said closing position. In the configuration assumed by the device (4) when the door (1 ) is at least partially open, said at least one elastic flexible element (11 ) is subjected to bending and tending to automatically move said door (1 ) to said closing position.
