Befestigungsvorrichtung für Lettersprossen, Werkzeugstiele o. dgl.Fastening device for letter bars, tool handles or the like. Zusatz zum Patent 693 555 Eine Verbesserung der Befestigungsvorrichtung für Leitersprossen, Werkzeugstiele 0. dgl., welche aus einem Keilmantel mit nach seiner Spitze hin sich verjüngendem Hohlraum bestellt, in den ein Keilkern leintreibbar ist, wird dadurch erreicht, daß der Keilmantel aus einem einzigen, nachträglich zusammengebogenen Stück besteht und daß zur Begrenzung der Einschlagtiefe der Keilmantel an seinem äußeren Ende mit seitlichen Vorsprüngen versehen ist. Addendum to Patent 693 555 An improvement in the fastening device for ladder rungs, tool handles 0 its tip ordered a tapering cavity into which a wedge core can be driven is achieved in that the wedge casing from a single, subsequently bent piece and that to limit the depth of impact of the wedge jacket is provided with lateral projections at its outer end. Ein Ausführungsbeispiel ist auf der Zeichnung dargestellt, und zwar zeigt Fig. 1 den Keilmantel a vor dem Zusammenbiegen in Draufsicht, Fig. 2 die Draufsicht des zusammengebogenen Keilmantels, Fig. 3 dessen Seitenansicht, Fig. 4 die in eine Leitersprosse eingetriebene Vorrichtung. An embodiment is shown in the drawing, namely Fig. 1 shows the wedge jacket a before bending together in plan view, Fig. 2 shows the plan view of the bent-together wedge jacket, Fig. 3 its side view, Fig. 4 in a Ladder rung driven device. Wie man aus den Fig. I bis 3 erkennen kann, läßt sich der - Keilinantel aus einem einzigen Stück, z. B. einem Stanz- oder Preßstück herstellen, das zusammengebogen wird, wobei Vorsprünge i' gebildet werden. Diese Vorsprünge verhindern das zu tiefe Eindringen des Keilmanteis beim Einschlagen desselben oder beim Eintreiben des Keilkerns e. Der Keilkernle ist unmittelbar hinter der Spitze im Längsschnitt mit Vertiefungenf versehen, in welche die nach innen gedrückten Zungen k des Keilmantels a fassen. As can be seen from FIGS. I to 3, the - wedge surface from a single piece, e.g. B. produce a stamped or pressed piece that is bent together is formed, thereby forming projections i '. These protrusions prevent it from being too deep Penetration of the wedge when it is hammered in or when the wedge core is driven in e. The wedge kernel is immediately behind the tip in a longitudinal section with indentations provided, in which the inwardly pressed tongues k of the wedge jacket grasp a. Diese Zungen k können beim Pressen bzw.These tongues k can be used when pressing or Ausstanzen des Keilmantels in einem Arbeitsgang nach innen durchgedrückt werden.Punching out the wedge casing in one operation will. Mit c sind innere Kerbschnitte bezeichnet, die das Auseinandergehen der Keilspitze m bei dem Eintreiben des Keilkerns e verhüten. With c internal notch cuts are designated, which diverge prevent the wedge tip m when driving in the wedge core e. Als Werkstoff kommt im allgemeinen Metall- bzw. Stahlblech in Frage, doch ist die Verwendung anderer geeigneter Werkstoffe nicht ausgeschiossen. As a material, sheet metal or sheet steel is generally used, however, the use of other suitable materials is not ruled out. P A T E N T A N S P R Ü C H E : I. Befestigungsvorrichtung für Leitersprossen, Werkzeugstiele o. dgl. nach Patent 693 555, dadurch gekennzeichnet, daß der Keilmantel (a) aus einem einzigen, nachträglich zusammengebog,enen Stück besteht und daß die Verjüngung des vom Keilmantel (a) eingeschlossenen Hohlraums (b) durch von außen her eingedrückte Zungen (k) gebildet ist. P A T E N T A N S P R Ü C H E: I. Fixing device for ladder rungs, Tool handles or the like according to Patent 693 555, characterized in that the wedge casing (a) consists of a single piece that was subsequently bent together and that the Tapering of the cavity (b) enclosed by the wedge casing (a) through from the outside pressed tongues (k) is formed. 2. Befestigun!gsvorrichtung nach Anspruch I, dadurch gekennzeichnet, daß der Keilmantel (a) an seinem äußeren Ende seitliche Vorsprünge (1) aufweist. 2. Fastening device according to claim I, characterized in that that the wedge casing (a) has lateral projections (1) at its outer end.
