Abstract

Die Erfindung betrifft eine ausziehbare Scherentreppe mit mindestens einem Abstützpunkt zur Abstützung im Bereich einer Öffnung, insbesondere Dachboden- oder Wandöffnung, mit zwei parallel und in einem Abstand zueinander angeordneten, zwischen sich Trittstufen aufweisenden Scherenholmen, von denen jeder mehrere, in Reihe angeordnete Scherenelemente aufweist, die jeweils zwei gekreuzte Scherenschenkel besitzen, welche in ihrem Kreuzungspunkt relativ zueinander schwenkbar verbunden sind und die an ihren Enden mit den Scherenschenkeln eines vor- und/oder nachgeordneten Scherenelements in Verbindungspunkten schwenkbar verbunden sind, wobei zumindest eine als Trittoberstufe definierte Trittstufe -in ausgezogener Stellung der Scherentreppeoberhalb des Abstützpunkts liegt, die sich dadurch auszeichnet, daß ein unterhalb der Trittoberstufe (15') liegender Scherenschenkel (11';11'';12';12'') mindestens eines der Scherenholme (9) einen Fortsatz (20) aufweist, der an seinem dem Scherenschenkel (11';11'';12';12'') abgewandten freien Endbereich (19) den Abstützpunkt (18) aufweist.

Figure 00000001
The invention relates to an extendable scissor staircase with at least one support point for support in the area of an opening, in particular an attic or wall opening, with two scissor bars which are arranged in parallel and at a distance from one another and have treads between them, each of which has a plurality of scissor elements arranged in series. which each have two crossed scissor legs, which are pivotally connected at their crossing point relative to one another and which are pivotally connected at their ends to the scissor legs of an upstream and / or downstream scissor element in connection points, with at least one step defined as the upper step - in the extended position of the Scissor stairs above the support point, which is characterized in that a scissor leg (11 ';11'';12'; 12 '') below the step (15 ') has at least one of the scissor bars (9) with an extension (20), the one on his scissors kel (11 ';11'';12'; 12 '') facing away from the free end region (19) has the support point (18).
