Abstract (en)
[origin: EP0026740A1] 1. Screwed crown, rotatable around its axis relative to a housing (5), particularly for time-measuring devices, comprising a crown body (1) and a threaded part (8, 28) not rigidly connected with the crown body and permanently screwed with a counter-threading (7, 27), of which the crown body (1) is rigidly connected to a setting or winding shaft (3), and in which, in the screwed condition, a gasket acting as a pressure gasket (10, 25) is compressed by the threaded part (8, 28), the crown being fastened to a sleeve (4, 5) rigidly connected to the housing (5), characterized in that the threaded part (8, 28), in loose condition, may be made active or inactive by an axial displacement relatively to the crown body (1) and in that the threaded part (8, 28), when active, may be displaced axially with respect to the housing and/or to the crown body by a rotation of the crown body in one or the other direction, for loading or unloading the pressure gasket (10, 25) in the crown.
