The balcony system includes a balcony unit adapted to project from the building opening, a counterforce unit adapted to compensate for forces applied to the balcony unit, and a first connecting element connecting the balcony unit and the counterforce unit. The counterforce unit comprises a base unit, a top unit on the base unit, and a second connecting element. The base unit is configured for stationary installation with respect to the building structure, such as for stationary installation on a floor of the building structure. The first connecting element connects the balcony unit and the top unit. The second connecting element connects the top unit and the base unit. The top unit is movable relative to the base unit. ## Claims ### Claim at position 1 1-15. (canceled) ### Claim 16 A balcony system for use with a building opening of a building structure, the balcony system comprising: a balcony unit adapted to project out of the building opening; a counterforce unit adapted to compensate for forces acting on the balcony unit; and a first connecting element connecting the balcony unit and the counterforce unit, wherein the counterforce unit comprises a base unit, a top unit and a second connecting element, wherein the base unit is adapted for stationary installation with respect to the building structure, such as for stationary installation on a floor of the building structure, and wherein the first connecting element connects the balcony unit and the top unit, and the second connecting element connects the top unit and the base unit, wherein the top unit is movable relative to the base unit. ### Claim 17 (depends on 16) The balcony system of claim 16, wherein the second connecting element comprises a rail on the underside of the top unit. ### Claim 18 (depends on 16) The balcony system according to claim 16, wherein the first connecting element connects the balcony unit and the top unit in a first connecting region by a first rail system. ### Claim 19 (depends on 18) The balcony system of claim 18, wherein the first rail system comprises a first rail on the underside of the balcony unit and comprises two spaced apart roller units disposed on the top of the top unit, the rollers of which engage the first rail on the underside of the balcony unit. ### Claim 20 (depends on 16) The balcony system of claim 16, wherein the second connecting element connects the top unit and the base unit in a second connecting region by a second rail system, wherein the second rail system comprises a rail on the underside of the top unit. ### Claim 21 (depends on 20) The balcony system of claim 20, wherein the second rail system comprises two spaced apart roller units disposed on the top of the base unit, the rollers of which engage the rail on the underside of the top unit. ### Claim 22 (depends on 16) The balcony system according to claim 16, wherein the balcony unit is movable relative to the top unit by the first connecting element. ### Claim 23 (depends on 16) The balcony system according to claim 16, wherein the counterforce unit comprises a counterweight for compensating at least a major part of the forces acting on the balcony unit, the counterweight being arranged in the top unit. ### Claim 24 (depends on 16) The balcony system according to claim 16, wherein the top unit comprises a support element adapted for force transmission to the building structure before, during and after relative movement between the top unit and the base unit that is stationary with respect to the building structure. ### Claim 25 (depends on 24) The balcony system of claim 24, wherein the support element comprises a roller. ### Claim 26 (depends on 16) The balcony system according to claim 16, wherein the top unit is configured as a linearly movable clamped beam. ### Claim 27 (depends on 16) The balcony system according to claim 16, wherein the top unit is configured as a linearly movable clamped beam supported at the front end. ### Claim 28 (depends on 16) The balcony system according to claim 16, wherein the base unit comprises a basic module, wherein the basic module is arranged to absorb forces exerted by the balcony system and to transmit them to the floor of the building structure. ### Claim 29 (depends on 16) The balcony system according to claim 16, wherein the base unit comprises a basic module and a structural module, wherein the basic module is arranged to absorb forces exerted by the balcony system and to transmit them to at least one of the floor of the building structure and the structural module. ### Claim 30 (depends on 29) The balcony system of claim 29, wherein the structural module is configured to compensate for at least one of floor unevenness and floor inclinations of the floor of the building structure, and to distribute forces exerted by the balcony system over a floor area of the floor of the building structure, wherein the structural module comprises at least one component from the group consisting of a floor plate, a beam and a base. ### Claim 31 (depends on 16) The balcony system of claim 16, wherein the base unit comprises an add-on module, wherein the add-on module is adapted for stationary installation with respect to the building structure, and wherein the add-on module makes the base unit a piece of furniture. ### Claim 32 (depends on 16) The balcony system according to claim 16, wherein the height of the counterforce unit is at least a parapet height of a parapet of the building opening, wherein the height of the base unit is greater than the height of the top unit. ### Claim 33 (depends on 16) The balcony system according to claim 16, wherein the balcony system has at least one of the following properties: a) the balcony system is a statically closed system; b) the counterforce unit is set up to compensate for forces acting on the balcony unit without interfering with the building structure; (c) the balcony system is essentially building structure non-invasive. ### Claim 34 Use of a balcony system as a temporary balcony for a building opening, such as a window, the balcony system comprising: a balcony unit adapted to project out of the building opening; a counterforce unit adapted to compensate for forces acting on the balcony unit; and a first connecting element connecting the balcony unit and the counterforce unit, wherein the counterforce unit comprises a base unit, a top unit and a second connecting element, wherein the base unit is adapted for stationary installation with respect to the building structure, such as for stationary installation on a floor of the building structure, and wherein the first connecting element connects the balcony unit and the top unit, and the second connecting element connects the top unit and the base unit, wherein the top unit is movable relative to the base unit. ### Claim 35 A method for setting up a temporary balcony, comprising: setting up a balcony system in a building structure having a building opening, wherein the balcony system comprises: a balcony unit adapted to project out of the building opening; a counterforce unit adapted to compensate for forces acting on the balcony unit; and a first connecting element connecting the balcony unit and the counterforce unit, wherein the counterforce unit comprises a base unit, a top unit and a second connecting element, wherein the first connecting element connects the balcony unit and the top unit, and the second connecting element connects the top unit and the base unit, wherein setting up the balcony system comprises setting up the base unit of the balcony system stationary with respect to the building structure; moving the top unit relative to the base unit so that the balcony unit connected to the top unit is moved in front of the building opening; and moving the balcony unit relative to the top unit so that the balcony unit protrudes from the building opening.
