Abstract:
1. A lifting device adapted to be mounted in an openable structure for assisting in opening a first member of the structure relative to a second member of the structure, comprising a biased slide shoe adapted to be slidable with respect to the second or first member of said structure so as to change a position of said slide shoe, a lifting arm having two ends, one end adapted to be pivotally connected with the first or second member of the structure and the other end associated with said slide shoe, and a braking device comprising at least one brake shoe slidable on a respective brake face of said lifting device, said braking device modulating a force resulting from the bias on said biased slide shoe in variation of said position of said slide shoe, characterized by further comprising an adjusting device adapted to adjust said modulation of said force when said lifting device is in a mounted position on said openable structure, said adjusting device comprising a manipulation member, which when manipulated by a user activates said adjusting device to adjust a brake force of said brake shoe exerted on said brake face independently from said position of said slide shoe.
