Claims (3)

1. Klappmechanismus für Fahrräder, der im wesentlichen ein oberes Rahmenrohr (2), ein inneres Rohr (3) und eine Schubstange (41) umfaßt, wo­ bei das obere Rahmenrohr (2) in einen ersten Abschnitt (21) und einen zweiten Abschnitt (22) unterteilt ist, wovon die aneinander anliegenden Enden jeweils mit einem Flansch (211, 221) versehen sind, um einen Drehpunkt zu bilden, wobei die beiden Abschnitte (21, 22) um diesen Drehpunkt als Zentrum um­ geklappt werden können, dadurch gekennzeichnet, daß
der erste Abschnitt (21) des oberen Rahmenrohrs (2) das innere Rohr (3), eine am äußeren Umfang des ersten Abschnitts (21) vorgesehene Fallklinke sowie die Schubstange (41), die in die Fallklinke (212) eindringt, um sie mit dem inneren Rohr (3) zu verbinden, so daß sich die Schubstange (41) in die Fallklinke (212) bewegt, umfaßt,
das innere Rohr (3) im ersten Abschnitt (21) des oberen Rahmenrohrs (2) in den Verbindungsabschnitt zwischen den ersten und zweiten Abschnitten (21, 22) des oberen Rahmenrohrs (2) vorsteht und
ein Zusammenklappen der beiden Abschnitte (21, 22) dann, wenn durch sie das innere Rohr (3) verläuft, verhindert wird, so daß die Strukturfestigkeit des Klappmechanismus im ausgeklappten Zustand erhöht ist.1. folding mechanism for bicycles, which essentially comprises an upper frame tube ( 2 ), an inner tube ( 3 ) and a push rod ( 41 ), where the upper frame tube ( 2 ) in a first section ( 21 ) and a second section ( 22 ) is divided, of which the abutting ends are each provided with a flange ( 211 , 221 ) to form a fulcrum, the two sections ( 21 , 22 ) being able to be folded around this fulcrum as the center, characterized in that that
the first portion ( 21 ) of the upper frame tube ( 2 ), the inner tube ( 3 ), a drop pawl provided on the outer periphery of the first portion ( 21 ), and the push rod ( 41 ) penetrating into the drop pawl ( 212 ) to be carried with it connect the inner tube ( 3 ) so that the push rod ( 41 ) moves into the drop pawl ( 212 ),
