Title (EN) COMPONENT COMPRISING SCREW BOSS AND METHOD FOR CONNECTING A COMPONENT
(FR) PIÈCE ÉQUIPÉE D'UN BOSSAGE POUR VIS ET PROCÉDÉ D'ASSEMBLAGE D'UNE PIÈCE
(DE) BAUTEIL MIT SCHRAUMDOM UND VERFAHREN ZUM VERBINDEN EINES BAUTEILS
Abstract:
(EN) The invention relates to a component (1) comprising a screw boss (2) for receiving a screw (3), the screw boss (2) typically protruding out of the component (1) and being connected to the component (1) in such a way that together they form a single component. Said screw boss (2) comprises a cavity (5) surrounded by a wall (4) which is open towards the insertion side (6) of the screw (3). The screw boss (2) has reinforcements (7) between which there is a partial weakening (8) of the wall (4). As a result of said weakening (8), the wall (4) of the screw boss (2) is yielding and can be displaced. The wall (4) is also substantially thinner than those of conventional screw bosses and can therefore give. As a result, the non-threaded screws can be used for both foamed injection-moulded parts and compact injection-moulded parts.
(FR) L'invention concerne une pièce (1) équipée d'un bossage pour vis (2) conçu pour accueillir une vis (3), le bossage pour vis (2) faisant saillie, de manière caractéristique, hors de la pièce (1) et étant relié de manière monobloc à cette pièce (1). Ce bossage pour vis (2) comporte une cavité (5) entourée d'une paroi (4) et ouverte vers le côté d'introduction (6) de la vis (3). Ledit bossage pour vis (2) comporte des renforcements (7) entre lesquels la paroi (4) présente un affaiblissement (8) partiel. Cet affaiblissement (8) rend la paroi (4) du bossage pour vis (2) déformable et elle peut ainsi être déplacée. Cette paroi (4) est aussi sensiblement plus fine que la paroi des bossages pour vis classiques et peut ainsi fléchir. Ainsi, les vis ne formant pas de filet pour des pièces moulées par injection et expansées peuvent aussi être utilisées pour des pièces moulées par injection compactes.
(DE) Ein erfindungsgemäßes Bauteil (1) weist einen Schraubdom (2) zur Aufnahme einer Schraube (3) auf, wobei der Schraubdom (2) typischerweise aus dem Bauteil (1) herausragt und einstückig mit dem Bauteil (1) verbunden ist. Dieser Schraubdom (2) weist einen von einer Wandung (4) umgebenen Hohlraum (5) auf, der zur Einführseite (6) der Schraube (3) geöffnet ist. Der Schraubdom (2) weist Versteifungen (7) auf, zwischen denen eine partielle Schwächung (8) der Wandung (4) vorliegt. Durch diese Schwächung (8) wird die Wandung (4) des Schraubdoms (2) nachgiebig und kann verdrängt werden. Die Wandung (4) ist also wesentlich dünner als bei herkömmlichen Schraubdomen und kann somit nachgeben. Wodurch die nicht-gewindefurchenden Schrauben für geschäumte Spritzgussteile auch für Kompaktspritzgussteile anwendbar werden.
