Brieföffner aus Holz haben üblicherweise den Nachteil, daß ihre Schneide durch die Beanspruchung beim Auftrennen von Briefumschlägen leicht schartig wird. Zum Öffnen von Standardbriefen mit einer gefalzten Verschlußlasche bedarf es keiner messerscharfen Schneide; dieser Falz läßt sich mit einer hinreichend verjüngten Kante sauber trennen. Trotzdem verfügt Holz nicht über genügend Festigkeit und Härte, den Belastungen durch die Kerbwirkung standzuhalten. Die Erfindung nach Schutzanspruch 1 ermöglicht es, die Stabilität der schneidenden Kante durch die Integration einer Verstärkung in den Holzkörper zu erhöhen. Die Verstärkungseinlage gewinnt dadurch nicht die Eigenständigkeit einer Klinge, so daß die optischen und haptischen Gestaltungsmöglichkeiten des Holzes für den gesamten Korpus des Brieföffners erhalten bleiben. Die Verstärkungseinlage läßt sich als zierendes aber nicht prägendes Element nutzen.Letter openers made of wood usually have the disadvantage that their blades become slightly jagged due to the stress of opening envelopes. A razor-sharp blade is not required to open standard letters with a folded flap; this fold can be cleanly separated with a sufficiently tapered edge. Nevertheless, wood does not have enough strength and hardness to withstand the stresses caused by the notch effect. The invention according to claim 1 makes it possible to increase the stability of the cutting edge by integrating a reinforcement into the wooden body. The reinforcement insert does not gain the independence of a blade, so that the optical and tactile design options of the wood are retained for the entire body of the letter opener. The reinforcement insert can be used as a decorative but not a defining element.
Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt:The drawing shows an embodiment of the invention:
Zwischen den hölzernen Korpushälften (1) eines Brieföffners ist eine dünne Platte aus einem Verstärkungsmaterial (2) eingeklebt.A thin plate made of a reinforcing material (2) is glued between the wooden body halves (1) of a letter opener.
Die flächen-symmetrische Formgebung des Brieföffners läßt diese Platte im Griffbereich nur in der Draufsicht (Fig. 2) als feine Linie erscheinen. An den Stellen, an denen der Korpus schneidenartig verjüngt ist, tritt die Platte in der Seitenansicht (Fig. 1) konturverstärkend flächig hervor und bildet gleichzeitig die Schneidkante.The surface-symmetrical shape of the letter opener means that this plate in the handle area only appears as a fine line when viewed from above (Fig. 2). At the points where the body is tapered like a cutting edge, the plate protrudes in a flat shape when viewed from the side (Fig. 1), reinforcing the contour and simultaneously forming the cutting edge.
Für den Holzkorpus des Brieföffners bleibt damit die Gestaltungsfreiheit erhalten.This means that the design freedom for the wooden body of the letter opener is retained.
