Abstract:
1. A catching device between a first structure and a second structure which can move with respect to each other, comprising a bolt which is pivotally mounted to the first structure, said bolt being adapted to be engaged, when appropriate, with a retaining means provided on the second structure, wherein said bolt includes a lever end, an elastic return means mounted between the first structure and the lever end tending to bring the bolt back to a retracted position; and a corresponding stop means on the second structure being adapted to contact the lever end and maintain the catching device in a taut state when the second structure is in the proximity of the first structure, said taut state being determined such that, when the first structure is rapidly spaced apart from the second structure causing a rapid release of the stop mean, said bolt, returning toward its retracted position under the action of the elastic return mean, and said retaining means engage with each other, thus limiting the relative spacing between the first structure and the second structure, and, on the other hand, when the spacing is slow, causing a gradual and relatively slow release of the stop mean, said bolt, returning in the same way toward its retracted position, and said retaining means remain separated, thereby allowing complete opening between the first structure and the second structure.
