LIFTING DEVICE
First Claim
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, comprisinga biased slide shoe adapted to be slidable with respect to the second or first member of said structure,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, anda 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 a magnitude of said force,characterized by further comprisingan adjusting device adapted to adjust when said lifting device is in a mounted position on said openable structure said modulation of said force, 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 in a given position of said brake shoe.

Abstract
The lifting device comprises a biased slide shoe adapted to be slidable with respect to a member of an openable structure, a lifting arm having two ends, one end adapted to be pivotally connected with a 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 the force resulting from the bias on said biased slide shoe. An adjusting device is adapted to adjust said progressive modulation of said force resulting from the bias on said biased slide shoe, and comprises 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 in a given position of said brake shoe.

15. 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, 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 a magnitude of said force, 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 adapted to be 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.
