Definitions

  • Embodiments of the present invention relate to a balcony system, more particularly to a balcony system with a counterforce unit, typically a counterweight unit. Furthermore, some embodiments relate to a temporary balcony system, wherein the balcony system additionally provides the functionality of a piece of furniture. Further embodiments relate to the use of such balcony systems as temporary balconies for building openings, for example for windows, and to methods for setting up a temporary balcony.
  • Temporary balconies are known to provide apartments without a conventional balcony with an outdoor balcony area.

  • This balcony system comprises a balcony unit which is designed to protrude from the building opening, a counterforce unit which is designed to compensate for forces acting on the balcony unit without interfering with the building structure, and a connecting element which connects the balcony unit and the counterforce unit.
  • Figs. 14-17 show one from EP 2 649 249 B1 known, mobile balcony system 100 ⁇ , which is located in a building structure 1, e.g. the room of an apartment.
  • the balcony system 100' stands on the floor of the building structure.
  • the balcony system 100' is compacted.
  • the balcony unit 110' of the balcony system 100' is dismantled, whereby Fig. 14 the floor 112' is located on top of the counterforce unit 120' and is connected to it by a connecting element 130' in the form of a rail system 132'.

  • a temporary balcony can be provided using the well-known balcony system.
  • assembly may require strength and care on the part of the user, particularly when moving the mobile balcony system and when positioning and aligning it in front of the window. It may be difficult for a single person to move the mobile balcony system through the room and find a stable, wobble-free position for use as a temporary balcony, particularly if the floor is still somewhat uneven. Careless movement of the mobile balcony system could also result in damage to the building wall by ramming. Careless, slanted alignment could, for example, damage the window if the balcony unit tilts during assembly or dismantling. Moving the mobile balcony system can also lead to increased wear and tear on the floor.
  • the mobile balcony system could be pushed to places in the building structure that are not structurally designed for this load, which would pose a risk to life and limb.
  • this mobile balcony system can be transformed into a piece of furniture, but the design freedom regarding the type, shape, weight and function of the piece of furniture is limited by its function as a mobile balcony system.

  • the second connecting element can for this purpose comprise, for example, a rail on the underside of the attachment unit.
  • Another embodiment involves using a balcony system described herein as a temporary balcony for a building opening, typically a window.
  • a method for setting up a temporary balcony comprises setting up a balcony system described herein in a building structure having a building opening, wherein setting up the balcony system comprises setting up the base unit of the balcony system in a fixed position with respect to the building structure.
  • the method further comprises moving the attachment unit relative to the base unit so that the balcony unit connected to the attachment unit is moved in front of the building opening, and moving the balcony unit relative to the attachment unit so that the balcony unit protrudes from the building opening.
  • statically closed system or equivalently “statically self-contained system” used herein means that such a system is capable of free standing, i.e. it only needs the floor on which it stands to at least support its own weight forces. to compensate.
  • a statically closed balcony system can typically compensate not only its own weight without tipping over, but also the weight of a load (up to a specified maximum load) and possibly also forces acting from the side.
  • statically closed system does not exclude the possibility that such a system, although in principle capable of free standing, can nevertheless transfer forces to the building structure at places other than its base, e.g. by means of pressure devices such as in EP 2 649 249 B1 described.
  • statically closed system does not necessarily have to be free-standing, but must have the ability to do so.
  • non-interference with the building structure means that a corresponding system that does not interfere with the building structure is intended and set up for a connection to a building structure that does not entail any interference with the building structure.
  • An interference with the building structure occurs in particular when the system comprises screws, bolts, nails, anchors or similar brackets that penetrate the building structure in order to connect the system to the building structure, or that are intended to do so.
  • a permanent connection to the building structure e.g. by welding or gluing or similar measures, also entails an interference with the building structure, and a system that is permanently connected to the building structure is not to be regarded as non-interference with the building structure.
  • pressing devices e.g. stamps, that only press against the building structure, e.g. laterally against the building opening, and are released after use, are not regarded as interfering with the building structure.
  • a system is "essentially structurally free” if it intervenes in the building structure with at most one or more statically insignificant parts.
  • the one or more parts are statically insignificant if they cannot, alone or in combination, support the dead weight of the system; in the case of a balcony system, they may not support the dead weight and a specified maximum load that may result from safety regulations.

According to some embodiments, the balcony system is essentially free of building structure intervention or even free of building structure intervention. According to further embodiments, the balcony system is statically closed and essentially free of building structure intervention. According to some embodiments, the balcony system is a temporary, statically closed and/or building structure-free balcony system.
  • the balcony system can be free-standing. A free-standing balcony system essentially transfers no forces to the building structure outside of its base. Only an insignificant force transfer takes place if it has no supporting function. A free-standing balcony system can, for example, contact parts of the building structure other than its base purely by touching, e.g. the wall in front of a window or the window sill, without statically activating them.

  • the base unit can be designed to assume a flat state and a high state.
  • the height of the base unit in the high state together with the height of the part of the attachment unit sitting on the base unit, can form an operating height of the counterforce unit that corresponds at least to the parapet height of the building opening, i.e., for example, at least 60 cm or at least 90 cm high.
  • the height of the base unit in the high state can be more than 60%, more than 70%, more than 80% or even more than 90% of the total operating height of the counterforce unit.
  • the height of the base unit in the high state can thus essentially compensate for the parapet height of the building opening.
  • the height of the base unit in the flat state together with the height of the part of the attachment unit sitting on the base unit, can form a basic height of the counterforce unit.
  • the base height of the counterforce unit can be less than 60 cm, less than 50 cm or even less than 40 cm.
  • the height of the base unit when flat can be less than 50 cm, less than 40 cm or even less than 30 cm.
  • a height-adjustable base unit can comprise a lifting system.
  • the lifting system can be configured to move the base unit from the flat state to the raised state and vice versa.
  • the lifting system can be mechanical, electromechanical, hydraulic or a combination thereof.
  • the lifting system can comprise a scissor lift.
  • the scissor lift can comprise a base plate.
  • the base plate can correspond to the base plate of the static module or be a part thereof.
  • the scissor lift can comprise a cover plate.
  • the scissor lift can have one, two or more scissors.
  • the scissor or scissors of the scissor lift can be located between the base plate and the cover plate and connected to them.
  • the top of the cover plate can form the top of the base unit.
  • the scissor lift can be manually or electrically operated.
  • Figs. 18 and 19 show an embodiment of the balcony system 100, which has a height-adjustable base unit 220.
  • Fig. 18 the height-adjustable base unit 220 in the flat state and the counterforce unit 120 in the basic state
  • Fig. 19 the height-adjustable base unit 200 in the raised state and correspondingly the counterforce unit 120 in the operating state.
  • the height-adjustable base unit 220 comprises a scissor lift 251, which has a base plate 253, a cover plate 255, a first scissor 257 and a second scissor 259.
  • the attachment unit 225 does not have its own support element in this embodiment. Instead, the balcony system comprises a static module, which comprises an attachment element 428.
  • the attachment element 428 comprises a body 429 and a connecting piece 427.
  • the attachment element 428 is fixed to the building opening 10 and extends vertically, so that the height of the attachment element 428 is equal to the height of the base unit 220 in the raised state.
  • the attachment element 428 is thus dimensioned such that the attachment unit 225 rests on the attachment element 428 when extended and can rest on it.
  • the connecting piece 427 ensures that the attachment unit 225 slides on the attachment element 428 and can connect both parts to one another in a force-fitting manner, whereby the connection can be released.
  • a connecting piece of the attachment element can consist of one or more elements from the group: rollers, bolts, latches, screws and clamps.
  • the connecting piece 427 comprises a pair of rollers 426 onto which the attachment unit 225 can slide and a bolt 425 which releasably connects the attachment unit 225 and the attachment element 428.
  • the combination of the pair of rollers 426 and the bolt 425 connects the attachment unit 225 and the attachment element 428 in a force-flush manner.
  • the pair of rollers 426 is designed to be foldable, so that when folded, as in Fig. 18 shown, is subject to less contamination, while at the same time the surface of the mounting element 428 can serve as a storage surface or the like.
