CA 2352799

A simple and compact hinge structure pivotally and detachably fixes a lid (110) to a housing (101). The hinge structure has a shaft (111) provided for the housing and a bearing unit (107) provided for the lid. The bearing unit has a shaft-attaching/detaching opening (175) for attaching or detaching the shaft in the axial direction. The bearing unit further includes a first bearing (171) for receiving one portion of the peripheral surface of the shaft and a second bearing (173) for receiving another portion of the peripheral surface of the shaft. The space between the first bearing and the second bearing becomes narrower as it is closer to the shaft-attaching/detaching opening. The second bearing is formed of a leaf spring (174). With this arrangement, even if an excessive force is applied to the lid or the housing, it is possible to prevent both the elements from being destroyed.

L'invention concerne une structure articulée simple et compacte permettant de fixer pivotant et amovible un couvercle sur un boîtier. La structure articulée comporte une tige destinée au boîtier et une unité d'appui destinée au couvercle. L'unité d'appui comporte une ouverture de fixation/libération de la tige destinée à la fixation ou à la libération de la tige dans le sens axial. L'unité d'appui comprend également un premier support destiné à recevoir une partie de la surface périphérique de la tige et un second support destiné à recevoir une autre partie de la surface périphérique de la tige. Le premier support et le second support sont en vis-à-vis. L'espace entre le premier support et le second support rétrécit à mesure que l'on se rapproche de l'ouverture de fixation/libération de la tige. Le second support est constitué d'un ressort à lames. Grâce à cette configuration, même en cas d'application d'une force excessive sur le couvercle ou le boîtier, la destruction de ces deux éléments peut être évitée.
