Lifting device adapted to be mounted in an openable structure

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, said slide shoe being biased by means of a spring arrangement,
• 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 abutment member with a slide face abutting a corresponding slide face of said brake shoe, at least one of said slide faces being inclined with respect to a sliding direction of said slide shoe,
• one of said abutment member and said brake shoe being connected to said spring arrangement, and the other being axially fixed in relation to said slide shoe or in relation to that of said first and second members with respect to which said biased slide shoe is adapted to be slidable such that movement of said slide shoe in relation to said first or second member of said structure causes said slide face of said abutment member to slide on said slide face of said brake shoe providing a wedging effect between said brake shoe and said abutment member, which modulates a brake force of said brake shoe exerted on said brake face dependent on a position of said slide shoe with respect to said second or first member of said structure.
