Description

Schnäpper Die Erfindung betrifft einen Schnäpper mit einer in einer Gabel gelagerten Rolle und mit einem die Gabel aufnehmenden und führenden Gehäuse und kennzeichnet sich dadurch, daß die aus einem elastischen Kunststoff bestehende Gabel mit Achsstummeln in die Rolle eingreift.Snap The invention relates to a snap with one in one Fork mounted role and with a housing receiving and guiding the fork and is characterized in that it consists of an elastic plastic Fork engages with stub axles in the role.

Es ist bereits ein Schnäpper mit einer in einer Gabel gelagerten Rolle und mit einem die Gabel aufnehmenden und führenden Gehäuse bekannt, bei dem in flache Metallstreifen Löcher eingestanzt sind, wobei die Metallstreifen zu der Gabel zusammengebogen werden. Diese Löcher bilden dann die Lager für Wellenstummel an der Gabel.It is already a catch with a roller mounted in a fork and known with a housing receiving and guiding the fork, in which in flat Metal strip holes are punched, the metal strips being bent together to form the fork will. These holes then form the bearings for the stub shafts on the fork.

Ziel der Erfindung ist die Schaffung einer Anordnung, die sich in besonders einfacher Weise aus Kunststoff herstellen läßt. Die Herstellung aus Kunststoff stößt deshalb auf Schwierigkeiten, weil immer solche Formkonstruktionen gewählt werden müssen, bei denen die Kerne und Formen einfach abziehbar sind. Bei einer Metallrolle bereitet es keine Schwierigkeiten, sie mit einstückigen Wellenstummeln zu versehen, während beim Gießen einer solchen Rolle aus Kunststoff zwangläufig eine Formteilung in diametraler Ebene vorhanden sein müßte, die jedoch einen unerwünschten Grat entstehen läßt, der anschließend in einem besonderen Arbeitsvorgang wieder beseitigt werden muß.The aim of the invention is to create an arrangement that is in can be produced in a particularly simple manner from plastic. Manufacture from plastic therefore runs into difficulties because such form constructions are always chosen where the cores and molds can be easily peeled off. At a It is not difficult for metal rollers to have them with one-piece shaft stubs to be provided, while inevitably when casting such a plastic roll a shape division in a diametrical plane would have to be present, which, however, is undesirable Burr can arise, which is then restored in a special process must be eliminated.

Beim Erfindungsgegenstand läßt sich die gesamte Konstruktion in einem Zug formen, wobei der Formarbeiter selbst die einzelnen Teile zusammensetzen kann, während der nächste Formling entsteht.When the subject of the invention, the entire construction can be in one Form the train, whereby the form worker can assemble the individual parts himself, while the next molding is being made.

Die Zeichnung zeigt in einer einzigen Figur einen Schnitt durch einen erfindungsgemäß ausgebildeten Schnäpper.The drawing shows a section through a single figure catch designed according to the invention.

Der erfindungsgemäße Schnäpper besteht im wesentlichen vollständig aus nachgiebigem Kunststoff und ist im Spritzgußverfahren hergestellt. Man erkennt aus der Zeichnung die Gabel l aus Kunststoff, die zwischen den Gabelschenkeln 2 eine Kunststoffrolle 3 aufnimmt, die auf gegenüberliegende, an den Gabelschenkeln 2 angeformte Achsstummel 4 aufgesetzt ist. Die Gabel t ist in einem aus Kunststoff bestehenden Gehäuse 5 verschiebbar, welches einen mit ihm einstückigen Flansch 6 aufweist, der mit Schraublöchern 7 zur Befestigung des Schnäppers an der Kantenfläche einer Tür versehen ist. Dabei steht die Achse der Rolle 3 senkrecht.The catch according to the invention is essentially complete made of flexible plastic and is manufactured by injection molding. One recognises from the drawing the fork l made of plastic, which between the fork legs 2 a plastic roller 3 receives the on opposite, on the fork legs 2 molded stub axles 4 is attached. The fork t is made of plastic existing housing 5, which has an integral flange 6 has, the screw holes 7 for attaching the catch on the edge surface a door is provided. The axis of the roller 3 is vertical.
