Title
(EN) EARMUFF
(FR) PROTECTEUR D'OREILLES
Abstract
(EN)
An earmuff assembly comprising two earmuffs (10) each provided with a respective sealing ring (12). A fork-shaped member (14) is pivotally connected on the one hand - at the end of each fork leg - to a corresponding earmuff (10) and on the other hand - centrally - to a resilient headstrap unit (16) at its other end. When the earmuff assembly is not in use, the earmuffs (10) can be collapsed towards one another beneath the headstrap (22) of the headstrap unit (16), for self-locking through the medium of the spring force in the headstrap (22). The connection between a fork-shaped member (14) and the headstrap unit (16) is effected through the medium of pivot hooks (28) provided on respective ends of the headstrap unit (16) or on the central part of the fork-shaped member (14) and intended for gripping coaction with one or more corresponding pivot pins (26) on the central part of the fork-shaped member (14) or on respective ends of the headstrap unit (16). The pivot hooks (28) can only be engaged with and released from the pivot pins (26) when the fork-shaped member (14) and the headstrap unit (16) are in a mutually predetermined position in which the earmuffs (10) are unattached in relation to the fork-shaped members (14). This position is latched by the earmuffs (14) subsequent to mounting the same.
(FR)
Ensemble protecteur d'oreilles qui comprend deux protecteurs d'oreilles (10) comportant chacun un anneau obturateur (12). Un élément en forme de fourche (14) est relié pivotant, d'un côté, au niveau de l'extrémité de chaque branche de la fourche, au protecteur d'oreille correspondant (10) et, de l'autre côté, au centre, à une unité serre-tête élastique (16) au niveau de son autre extrémité. Quand l'ensemble protecteur d'oreilles n'est pas utilisé, les protecteurs (10) peuvent être repliés l'un vers l'autre sous le serre-tête (22) de l'unité serre-tête (16), afin d'être autoverrouillés par la tension de ressort contenue dans le serre-tête (22). La liaison entre un élément en forme de fourche (14) et l'unité serre-tête (16) se fait par l'intermédiaire de crochets pivotants (28) disposés sur les extrémités respectives de l'unité serre-tête (16) ou sur la partie centrale de l'élément en forme de fourche (14), et prévus pour agripper ensemble un ou plusieurs tourillons (26) disposés sur la partie centrale de l'élément en forme de fourche (14) ou sur les extrémités respectives de l'unité serre-tête (16). Les crochets pivotants (28) ne peuvent s'engager dans les tourillons (26) et en être libérés que lorsque l'élément en forme de fourche (14) et l'unité serre-tête (16) sont l'un par rapport à l'autre dans une position prédéterminée, dans laquelle les protecteurs d'oreilles (10) sont libres par rapport aux éléments en forme de fourche (14). Cette position est verrouillée par les protecteurs d'oreilles (14) suite à leur montage.
