Abstract

The staples are contained in bar form in a magazine (2) and are moved towards the ejector-duct (3) by a spring-guided slide-piece. The tension spring is deflected by a deflector part which has a bearing block (5) containing a bearing spring (6) with an axle part (7). The spring leg (8) protrudes from the axle part and is formed by two parallel cantilevered arms. The free ends of the spring leg rest against the ejector blade and press the blade against the inner surface (9) of the end plate (10).

Description

Die Erfindung betrifft einen Handhefter mit lose aufge­ hängtem Stoßmesser zum Ausstoßen von Heftklammern, die stabförmig magaziniert auf einem Magazin geführt und über einen federgeführten Klammerschieber zum Ausstoß­ kanal verschiebbar sind, wobei die Zugfeder über einem einen Lagerbock zugeordneten Umlenkteil umlenkbar geführt ist.The invention relates to a stapler with loose hanging knife for ejecting staples guided in a rod-shaped magazine and via a spring-guided clamp slide for ejection are slidable, the tension spring over a a bearing block associated deflection deflectable is led.

Bei Handheftern der aufgezeigten Gattung müssen die jeweiligen Stoßmesser so positioniert sein, daß unter­ schiedlich breite Drähte von Heftklammern im Funktions­ betrieb immer an der Innenfläche einer Magazinstirn­ platte beaufschlagt werden. Hierbei muß das Spiel des Stoßmessers zwischen der Außenführung des Magazins und der Innenfläche der Magazinstirnplatte so groß sein, daß das Stoßmesser einwandfrei und leicht bewegbar ist.For staplers of the type shown, the each knife be positioned so that under different widths of staples in function always operated on the inside surface of a magazine front plate are applied. Here, the game of Butt knife between the outer guide of the magazine and the inside surface of the magazine faceplate should be so large that the knife is flawless and easy to move.

Bekannterweise sind bereits Stoßmesser so abgewinkelt, daß das Stoßmesser immer an der Innenfläche der Maga­ zinstirnplatte anliegt. Zur Erreichung dieser Vorgabe müssen die erforderlichen Abmessungen exakt eingehalten werden, was durch Materialunterschiede in der Härte und der Stärke nur bedingt erreichbar ist. Es ist auch bekannt, die Stoßmesser über zusätzliche Bauteile, z. B. Federn, so im Aufhängebereich zu führen, daß das Stoßmesser in Richtung zur Stirnplatte gedrückt wird. Hierzu müssen die Zusatzteile teilweise mit erheblichem Aufwand montiert werden.As is known, butt knives are already angled so that the knife is always on the inner surface of the Maga Interesting faceplate. To achieve this target  the required dimensions must be adhered to exactly be what due to material differences in hardness and the strength is only partially achievable. It is also known, the impact knives about additional components, e.g. B. springs, in the suspension area so that the Butt knife is pressed towards the face plate. To do this, the additional parts must be considerably Effort.

Der Erfindung liegt die Aufgabe zugrunde, das lose aufgehängte Stoßmesser mit einfachen Mitteln so zu positionieren, daß es unabhängig von der Breite des Steges der zur Anwendung kommenden Heftklammern immer an der Innenflä­ che der Magazinstirnplatte anliegt und dadurch immer nur eine Heftklammer beaufschlag- und abscherbar ist.The invention has for its object that loose suspended knives with simple means position it regardless of the width of the web Use coming staples always on the inner surface surface of the magazine faceplate and therefore always only one staple can be applied and sheared off.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß im Lagerbock eine Lagerfeder angeordnet ist, wobei die Lagerfeder mit einem Achsteil im Lagerbock führbar angeordnet sein kann. In Ausgestaltung der Erfindung weist die Lagerfeder ein elastisches Federbein auf, das vom Achsteil auskragend angeordnet ist. Vorteilhafter­ weise ist das Federbein durch zwei parallelverlaufende Kragarme gebildet. Die Zugfeder kann: auf dem Achsteil der Lagerfeder umlenkbar geführt sein.This object is achieved in that a bearing spring is arranged in the bearing block, the Bearing spring can be guided in the bearing block with an axle part can be arranged. In an embodiment of the invention the bearing spring has an elastic strut that is arranged cantilevered from the axle part. More advantageous the strut is wise due to two parallel ends Cantilever arms formed. The tension spring can: on the axle the bearing spring can be guided deflectably.

Ein Ausführungsbeispiel der Erfindung ist in der Zeich­ nung dargestellt und wird nachfolgend näher beschrie­ ben. Es zeigen:An embodiment of the invention is in the drawing shown and will be described in more detail below ben. Show it:

Fig. 1 einen Vertikalschnitt durch einen Handhefter im Bereich des Stoßmessers; 1 is a vertical section through a hand stapler in the area of the butt diameter.

Fig. 2 eine Draufsicht auf einen Handhefter im Bereich des Stoßmessers; Figure 2 is a plan view of a hand stapler in the area of the butt diameter.

Fig. 3 eine Lagerfeder in der Seitenansicht und Fig. 3 is a bearing spring in side view

Fig. 4 eine Lagerfeder in der Draufsicht. Fig. 4 is a bearing spring in plan view.

Bekannterweise ist das Stoßmesser 1 lose im Oberteil 11 des Handhefters aufgehängt. Die stabförmig magazinier­ ten Heftklammern sind auf einem Magazin 2 geführt und über einen federgeführten Klammerschieber zum Ausstoß­ kanal 3 verschiebbar. Eine Lagerfeder 6 ist mit einem Achsteil 7 im Lagerbock 5 beweglich geführt, wobei die Lagerfeder 6 ein vom Achsteil 7 auskragendes elasti­ sches Federbein 8 aufweist. Wie Fig. 4 zeigt, besitzt das Federbein 8 zwei parallelverlaufende Kragarme.As is known, the butt knife 1 is loosely suspended in the upper part 11 of the hand stapler. The rod-shaped magazinier th staples are guided on a magazine 2 and can be moved via a spring-guided clamp slide to the discharge channel 3 . A bearing spring 6 is movably guided with an axle part 7 in the bearing block 5 , the bearing spring 6 having an elastic strut 8 projecting from the axle part 7 . As shown in FIG. 4, the strut 8 has two parallel extension arms.

Erfindungswesentlich ist, daß die Zugfeder 4 auf dem Achsteil 7 der Lagerfeder 6 umlenkbar geführt ist. Nach Fig. 1 liegen die freien Enden des Federbeins 8 am Stoßmesser 1 an und drücken damit das Stoßmesser 1 gegen die Innenfläche 9 der Stirnplatte 10.It is essential to the invention that the tension spring 4 is guided in a deflectable manner on the axle part 7 of the bearing spring 6 . According to FIG. 1, the free ends of the shock absorber 8 rest on the butt knife 1 and thus press the butt knife 1 against the inner surface 9 of the end plate 10 .
