KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei den bisher bekannten Klappstielen für Geräte sind die Stielteile an der Klappstelle zylindrisch ausgebildet und durch 'eine Tülle versteift worden, die an der Klappstelle durch Schrauben, Nocken, Haken, Nut und Stift u.. dgl. gehalten werden mußte. Abgesehen von den Verletzungen, die hervorstehende, teilweise scharfkantige Befestigungsmittel herbeiführen können, liegt ein Nachteil dieserIn the previously known folding handles for devices, the handle parts are at the folding point Cylindrical design and stiffened by 'a spout, which at the folding point through Screws, cams, hooks, groove and pin and the like had to be kept. Apart from that from the injuries, the protruding, partly sharp-edged fasteners can bring about is a disadvantage of this

ίο Ausführungen in der Empfindlichkeit gegen jede Verschmutzung, die die Benutzung erschwert oder gar unmöglich macht.ίο versions in sensitivity to any pollution that makes it difficult or even impossible to use.

Bei zylindrischer Ausbildung von Schaft und Tülle wird aber auch nicht vermiedenIn the case of a cylindrical design of the shaft and nozzle, however, this is also not avoided

ig werden können, daß zwischen beiden ein wenn auch geringfügiger Luftspalt bleibt, der eine beim Arbeiten sehr hinderliche Beweglichkeit der beiden Teile gegeneinander zur Folge hat. Diese Art der Befestigung muß völlig versagen, wenn die Stielteile aus Holz hergestellt und infolge von Feuchtigkeit gequollen oder durch Hitze zusammengetrocknet sind.There can be an if between the two even a slight air gap remains, which makes mobility very difficult when working of the two parts against each other. This type of fastening must fail completely, if the handle parts are made of wood and swollen as a result of moisture or have dried out from the heat.

Die geschilderten Nachteile werden vermieden, wenn die Tülle sowie die zugehörigen Stielteile an der" Klappstelle schwach kegelförmig zueinander passend ausgebildet werden. Es wird alsdann ohne jedes weitere Befestigungsmittel eine Versteifung- der Klappstelle dadurch erfolgen können, daß die Tülle auf den Kegel hinauf gedreht wird. Bei kegeliger Ausbildung der Stielteile wird dabei immer eine Stelle gefunden werden können, an der die Tülle prall sitzt und durch Reibung festgehalten wird, gleichviel, ob die Klappstelle verschmutzt, durch Feuchtigkeit gequollen oder infolge Hitze zusammengetrocknet ist.The disadvantages outlined are avoided if the grommet and the associated Handle parts are formed slightly conical to each other at the "folding point. It is then without any further fastening means a stiffening of the folding point can be done in that the spout is turned up on the cone. at conical design of the stem parts will always be able to find a place, on which the spout sits tightly and is held in place by friction, regardless of whether the Folded area dirty, swollen from moisture or dried up as a result of heat is.

In Fig·, ι bedeuten a, b die Teile eines ^Stieles, die in Richtung der Pfeile d, e vermittels des Gelenks c aufgeklappt werden können. Sobald sie, wie in Fig.. 3 dargestellt, übereinander stehen,' fällt die lose auf b befindliche volle oder auch ausgesparte Tülle f über das Gelenk und kann dort, wenn Tülle und Stiel schwach kegelig zueinander' passend ausgebildet sind, durch Reibung gehalten werden. Die. Gelenkverbindung selbst kann · beliebiger Art sein, beispielsweise mit mittlerer Gelenkzunge, wie in Fig\ 5 und 6 dargestellt. . .In Fig ·, ι a, b denote the parts of a ^ stem, which can be opened in the direction of arrows d, e by means of the joint c . As soon as they are on top of each other, as shown in Fig. 3, 'the full or recessed spout f located loosely on b falls over the joint and can be held there by friction if the spout and handle are slightly conical to each other' . The. The articulated connection itself can be of any type, for example with a central articulated tongue, as shown in FIGS. 5 and 6. . .
