Title: BRAKING SPRING DEVICE
Abstract:
A braking spring device comprises an elastic means (3), a guide means (5) and a carriage means (7) provided with a connection (8) for a tie-rod or a transmission for the connection to a hatch, a door or a hinge. The carriage means (7) is slidable along the guide means (5) between a retracted condition (R) and an extended condition. The elastic means (3) is connected between the guide means (5) and the carriage means (7), and transmits to the latter its own elastic force directed towards the retracted condition (R). The device (1) further comprises at least one drag means (9) which is connected to the carriage means (7) and which frictionally slides along a respective sliding wall (11) of the guide means (5).
