Description
FeIo - Werkzeugfabrik Holland-Letz GmbH D - 35279 Neustadt/Hessen Griff aus KunststoffFeIo - Werkzeugfabrik Holland-Letz GmbH D - 35279 Neustadt/Hessen Handle made of plastic
Die Neuerung betrifft die Gestaltung eines im Spritzgießverfahren aus zwei Materialien hergestellten Griffes aus Kunststoff.The innovation concerns the design of a plastic handle made from two materials using the injection molding process.
Griffe aus zwei Kunststoffen werden üblicherweise in der Weise hergestellt, daß ein Kerngriff aus einem Hartkunststoff gespritzt wird, und auf den Kerngriff in einer zweiten Spritzgießschicht ein Mantel oder Felder aus Weichkunststoff (Elastomerkunststoff) mit anderer Farbe als die des Kerngriffes aufgespritzt werden.Handles made of two plastics are usually manufactured by injection-molding a core handle made of a hard plastic, and then in a second injection-molding layer a jacket or panels made of soft plastic (elastomer plastic) of a different color to that of the core handle are injected onto the core handle.
Da bei Elastomerkunststoffen die Haftung von Druckfarben sehr schlecht ist, wird angestrebt, in einer Zone der Griffoberfläche den Kerngriff nicht mit einem Mantel aus Elastomer zu umhüllen. Unter dem Gesichtspunkt, eine gute Haptik des Griffes zu erzielen und hohe Drehmomente übertragen zu können, bietet sich der Griffhals als nicht ummantelte Zone an. Hier liegen die Fingerspitzen an, sie drehen den Griff beim schnellen Schrauben mit niedrigem Drehmoment.Since the adhesion of printing inks to elastomer plastics is very poor, the aim is not to cover the core handle with an elastomer coating in one area of the handle surface. From the point of view of achieving a good feel for the handle and being able to transmit high torques, the handle neck is a suitable area that is not coated. This is where the fingertips rest, turning the handle when screwing quickly with low torque.
Ist der Griffhals aus einem wenig rutschfesten Hartkunststoff, ist der Benutzer gezwungen dort eine große Haltekraft aufzubringen, um eine Kraft in Längsrichtung, gegen ein Herausrutschen der Werkzeugspitze, aufzubringen. Um diese zur Ermüdung führende Haltekraft zu reduzieren, sind seit langem trichterförmig ausgebildete Griffhälse bekannt.If the handle neck is made of a hard plastic that is not very slip-resistant, the user is forced to apply a large amount of holding force to prevent the tool tip from slipping out. Funnel-shaped handle necks have long been known to reduce this holding force, which leads to fatigue.
Die vorliegende Neuerung sieht einen Ring aus Weichkunststoff vor, der den Griffhals abschließt und ein Überrutschen der Finger, bzw. die Notwendigkeit einer hohen Haltekraft verhindert.The present innovation provides a ring made of soft plastic that closes the handle neck and prevents the fingers from slipping or the need for a high holding force.
Weiterhin wird angestrebt, den Anguß für den Weichmantel an eine Stelle des Griffes zu legen, wo es einerseits möglich ist, den Angußkanal in die Form-Trennebene zu legen, was den Anguß technisch sehr einfach macht, andererseits ein am Griff verbleibender kleiner Angußnippel jedoch nicht stört. Eine solche Stelle ist die Stirnseite des Griffkopfes, oder ein kurzer, axialer Ansatz an der Stirnseite, oder der Umfangsbereich des Griffkopfes.Furthermore, the aim is to place the sprue for the soft coating at a point on the handle where it is possible to place the sprue channel in the mold parting plane, which makes the sprue technically very simple, but at the same time a small sprue nipple remaining on the handle does not cause any problems. One such point is the front side of the handle head, or a short, axial extension on the front side, or the peripheral area of the handle head.
Die Verbindung vom Angußbereich am Griffkopf zu dem ummantelten Bereich des Griffes wird über Verbindungsstege oder- Kanäle hergestellt, die durch die nicht ummantelte Zone des Griffhalses verlaufen.The connection from the sprue area on the handle head to the coated area of the handle is made via connecting bars or channels that run through the non-coated zone of the handle neck.
