Definitions

  • the present invention relates to a partition system for use in halls, such as sports halls.
  • the acoustics in sport halls is known to give rise to complaints from users, especially from people who must work in such halls, such as trainers and teachers.
  • To improve the acoustic characteristics of sports halls it is known to cover the walls, ceiling and floor with panels of sound absorbing material.
  • the invention relates to an acoustic partition system, comprising a partition carrier, at least one pair of partition screens comprising sound absorbing material, that are interconnected at a predetermined distance and arranged on the partition carrier and motorized moving means for simultaneously moving the partition screens with respect to the partition carrier.
  • EP1174063 describes a partition curtain for use in halls, such as sports halls, comprising a curtain carrier, at least one pair of curtain sheets comprising sound absorbing material, that are interconnected at a predetermined mutual distance and arranged on the curtain carrier and motorized moving means for simultaneously moving the curtain sheets with respect to the curtain carrier.
  • a layer of sound absorbing material is arranged on the outside of the curtain sheets.
  • the invention has for its object to provide a partition system with improved sound isolation and improved sound absorption. More specifically the invention has for its object to provide a partition system that can full fill the noise standards for sports halls that are formulated as directives by several institutions, such as NOC NSF and ISA/Kiwa.
  • the partition system comprises two or more chambers defined between the partition screens and the partition screens are interconnected by a series of strips essentially extending over the width of the partition screens.
  • the strips are preferably made of sound isolating material.
  • the strips effectively define the chambers between the partition screens in which sound waves are attenuated.
  • the chambers are acoustic chambers wherein sound waves are effectively attenuated.
  • the chambers allow use of different partition screen materials with different acoustic characteristics for different chambers, thus providing an instrument for detailed sound control. Applicant expects the partition system to have high sound absorbing ability, particularly with respect to mid- and low frequency sounds.
  • the partition screens are interconnected by a series of the strips spaced apart in height direction of the partition system.
  • the strips or vanes offer a better sound control by forming a barrier for sound travel in height direction of the partition system.
  • the chambers allow use of different partition screen materials with different acoustic characteristics in height direction of the partition system, thus providing an instrument for detailed sound control.
  • each partition screen comprises a series of alternated screen panels and folding areas.
  • the predefined folding areas allow for a controlled folding of the screen panels during lifting of the partition system. This results in a compact package of screen panels in the opened position and a relatively shallow partition system in the closed position.
  • the strips are connected at the folding areas.
  • one or more of the screen panels comprise plates of sound absorbing material.
  • the plates enhance the stiffness of the screen panels and contribute to controlled folding of the partition system.
  • the moving means comprise pairs of pull bands that run parallel to the partition screens through the strips outside the centre of the strips.
  • the features of this embodiment force adjacent screen panels to fold onto each other.
  • the distance between the partition screens enlarges in the direction towards the partition carrier. This can be achieved by enlarging the width of the strips in the direction towards the partition carrier. Consequently, adjacent screen panels are urged to fold onto each other.
  • the partition system according to the invention comprises two or more partition modules, wherein each partition module is provided with module connecting means for releasably connecting partition modules at connecting areas.
  • the partition modules of this preferred embodiment can be prefabricated and interconnected in the sports hall. Consequently, mounting time is considerably reduced.
  • Each partition module can be separately replaced for maintenance or repair which advantageously is cost saving.
  • the partition modules allow for a wide variety of possibilities for composing the optimal acoustic characteristics of the partition system.
  • the partition system according to the invention further comprises strip connecting means for releasably connecting the strips to the partition screens.
  • the strips of this preferred embodiment can be prefabricated and interconnected in the sports hall. Thereby mounting time is considerably reduced. Each strip can be separately replaced for maintenance or repair which advantageously is cost saving. Each strip can be optimized to contribute to sound reduction. Preferably the strips are connected at the connecting areas.
  • the module and/or strip connecting means are zippers.
  • the zippers are reliable connecting means and can function as folding areas to contribute to the controlled lifting and folding of the partition system.
  • each partition module comprises at least one pair of partition screens interconnected by at least one strip.
  • each partition screen of a partition module comprises two screen panels alternated by a folding area.
  • the panels of each module fold onto each other and adjacent folded modules fold onto each other.
