Abstract (en)
[origin: EP0754830A1] An arm which is pivoted relative to the door frame, has one end connected to the door panel and the other to a balancer with a strap (10a) and spring(s) (10b) anchored to a fixed point. The balancer comprises a housing (12) fixed to the door frame, having two parallel side flanges in the shape of half discs and a support (13) connected to the pivoted arm. The support is equipped with a pivoted anchor (15) which interacts by friction or penetration with the flanges and is connected e.g. with the balancer strap. During normal operation of the balancer the anchor is in a raised position and makes no contact with the housing (12), while in the event of the balancer spring breaking it engages with the flanges and locks the door, preventing it from dropping under its own weight and causing possible injury.
