Technical Examples

The invention relates to a lifting apparatus for a two-leaf folding flap or folding door which can be pivoted about horizontal axes, consisting of a two-arm lever which is pivotably supported about a horizontal pivot axis on a side carcass part and whose longer arm is hinged to the lower leaf of the folding flap or folding door and of a pressure element whose one end is pivotably connected to the carcass part and whose other end is connected to the lever. In accordance with the invention, the longer lever arm of the two-arm lever is hingedly and displaceably connected to the lower leaf. Furthermore, the relative movement between the hinge point of the lever and the lower leaf is braked by a spring or friction force.
