Title
(EN) AXIALLY CENTRED QUARTER-TURN FASTENING DEVICE
(FR) DISPOSITIF DE FIXATION DE TYPE QUART DE TOUR AXIALEMENT CENTRE
Abstract
(EN)
The present invention relates to a quarter-turn fastening device (1) for fastening a part (2) to a support, the fastening device (1) comprising: a head (11) supporting the part (2), the head (11) being intended to abut a first surface of the support; a holding foot (12) connected to the head (11) and extending along a main axis (A), the holding foot (12) being configured to extend axially into an opening in the support, the opening having a peripheral edge, in order to arrange the fastening device (1) in an insertion position having a first angular orientation, the holding foot (12) comprising at least one flexible retaining tab (13) to abut a second surface of the support when the fastening device (1) is moved angularly from the insertion position to a locking position having a second angular orientation. The flexible tab (13) is equipped with a lug (15) for filling the space between the holding foot (12) and the edge of the opening and thus recentre the fastening device (1) in the opening when the fastening device (1) is moved angularly from the insertion position to the locking position.
(FR)
La présente invention concerne un dispositif de fixation (1), du type quart de tour, d'une pièce (2) à un support, le dispositif de fixation (1) comprenant : une tête (11) portant la pièce (2), la tête (11) étant destinée à prendre appui sur une première face du support; un pied de maintien (12) relié à la tête (11) et s'étendant selon un axe principal (A), le pied de maintien (12) étant configuré pour pénétrer axialement dans une ouverture du support, l'ouverture présentant un bord périphérique, pour ainsi disposer le dispositif de fixation (1) dans une position d'insertion présentant une première orientation angulaire, le pied de maintien (12) comportant au moins une languette flexible de retenue (13) pour prendre appui sur une deuxième face du support lorsque le dispositif de fixation (1) est déplacé angulairement de la position d'insertion à une position de verrouillage présentant une deuxième orientation angulaire. La languette flexible (13) porte un ergot (15) pour combler l'espace susceptible d'exister entre le pied de maintien (12) et le bord de l'ouverture et ainsi recentrer le dispositif de fixation (1) dans l'ouverture lorsque le dispositif de fixation (1) est déplacé angulairement de la position d'insertion à la position de verrouillage.
