Description
In ein Bockgerüst verwandelbare Trittleiter mit Laufbrett. Die Erfindung betrifft eine Trittleiter,, deren Einzelleitern auseinandergenommen werden können und dann mit einem auf die Sprossen zu legenden Laufbrett zu einem Bockgerüst hergerichtet werden können.Stepladder with walking board that can be transformed into a trestle. The invention relates to a stepladder whose individual ladders can be dismantled and then prepared to a trestle frame with a running board to be placed on the rungs can be.
Gegenüber bekannten derartigen Vorrichtungen zeichnet sich die Neuerung dadurch aus, daß die sämtlichen oder auch nur die oberen Sprossen der Leitern und das Laufbrett mit Ausklinkungen versehen sind, die so ineinamderfassen, dä.ß sowohl in der Längsrichtung als auch in der Querrichtung des Laufbrettes eine unverrückbare Verbindung zwischen Laufbrett und Leitern hergestellt wird, so daß mit Benutzung der bekannten Haltestangen feste Dreieckverbände hergestellt werden und somit ein festes Standgerüst ohne Benutzung besonderer Verschraubungen oder sonstiger Hilfsmittel erzielt wird.Compared to known devices of this type, the innovation stands out characterized in that all or only the upper rungs of the ladders and the running board are provided with notches which interlock so that both in the longitudinal direction as well as in the transverse direction of the running board an immovable one Connection between running board and ladders is made so that with use of the well-known handrails solid triangular braces are made and thus a Fixed scaffolding without the use of special screw connections or other aids is achieved.
In der Zeichnung ist die Erfindung dargestellt, und zwar zeigt: Abb. i die Trittleiter in Seitenansicht, Abb. z dieselbe in Vorderansicht, Abb. 3 die zerlegte Trittleiter mit dem Laufbrett als Standgerüst und Abb. q. eine Aufsicht auf das Laufbrett. Die Einzelleitern a werden durch eine Schraubspindel b, die durch die Seitenbeschläge c geführt wird, zur Trittleiter (Abb. i und a) vereinigt. Bei der Verwendung der Einzelleitern a als Stützleitern für das Standgerüst wird die Spindel b entfernt und das Laufbrett d so auf ein Paar der mit Ausschnitten e versehenen Sprossen f gelegt, daß das Laufbrett d mit seinen Ausklinkungen g über die Sprossen .faßt, so daß eine feste, unverrückbare Verbindung zwischen Laufbrett d und Stützleitern a geschaffen ist. Die an dem Laufbrett d angelenkten Haltestangen lt werden dann mit ihren Hakenenden in an. den Sprossen i angebrachte Ösen k eingehakt, bilden infolgedessen zwei Dreieckverbände und sichern dadurch die Standfestigkeit des Gerüstes.The invention is shown in the drawing, namely: Fig. I the stepladder in a side view, Fig. Z the same in a front view, Fig. 3 the dismantled stepladder with the running board as a stand and Fig. Q. a supervision of the running board. The individual ladders a are combined to form the step ladder (Fig. I and a) by means of a screw spindle b, which is guided through the side fittings c. When using the individual ladders a as support ladders for the stand frame, the spindle b is removed and the running board d placed on a pair of the rungs f provided with cutouts e that the running board d with its notches g .fasst over the rungs, so that a firm, immovable connection between the running board d and support ladders a is created. The holding rods lt hinged to the running board d are then connected with their hook ends in. The loops k attached to the rungs i , consequently form two triangular connections and thereby ensure the stability of the scaffolding.
