Title (EN) DEVICE CONTAINING A FORCE-IMPARTING MEANS AND EQUIPPED WITH SAFETY MEANS
(FR) DISPOSITIF DE COMMUNICATION DE FORCES MUNI D'UN DISPOSITIF DE SURETE
Abstract:
(EN) A spring-containing device comprises a housing including a removable end plate (2). A plurality of screw-threaded tie rods (7) have nuts (10) holding the end plate (2) in assembly with the housing. A safety plate (13) is disposed within the housing against the end plate (2) and clear of a movable spring-retaining plate (8) at its closest approach to the end plate (2). The safety plate (13) is fast on a shaft (15) rotatable in the end plate (2) and adapted (at 18) to be turned from outside. The safety plate (13) has recesses (15) in its peripheral edge (14) through which recesses (15) respective tie rods (7) can pass. The tie rods (7) have recesses (19) which can receive the unrelieved edge (14) of the safety plate (13) when in a certain angular position and thus prevent longitudinal relative movement between the safety plate (13) and the tie rods (7).
(FR) Un dispositif à ressort comporte un boîtier comprenant une plaque terminale détachable (2). Une pluralité de tirants filetés (7) possèdent des écrous (10) servant à garder la plaque terminale (2) solidaire du boîtier. Une plaque de sûreté (13) est disposée à l'intérieur du boîtier et contre la plaque terminale (2) de sorte qu'elle ne gêne pas une plaque amovible de retenue du ressort (8) lorsqu'elle se trouve dans sa position la plus proche de la plaque terminale (2). La plaque de sûreté (13) est solidaire d'un arbre (15) qui peut tourner dans la plaque terminale (2) et qui est adapté (18) pour être tourné à partir de l'extérieur. Cette plaque de sûreté (13) possède des évidements (15) périphériques permettant le pasage de tirants (7) respectifs. Les tirants (7) possèdent des évidements (19) aptes à recevoir le bord non dépouillé (14) de la plaque de sûreté (13) lorsqu'ils se trouvent dans une position angulaire particulière afin d'empêcher un déplacement relatif longitudinal entre la plaque de sûreté (13) et les tirants (7).
