Abstract
Description
- 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.
- Most sports halls are provided with one or more partition systems to divide the sports hall into smaller sections. Unfortunately, the acoustic characteristics deteriorate significantly, as soon as the partition systems are closed. Particularly, when a middle part of the hall is closed with partition systems at two sides, a considerable reverberation time combined with flutter-echoes is observed in the middle part of the hall.
- 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. In the known partition curtain 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.
- This object is achieved by the partition system described above, wherein 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. In addition, 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.
- In a first preferred embodiment 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.
- According to an elegant preferred embodiment of a partition system according to the invention 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. Preferably the strips are connected at the folding areas.
- According to a further elaboration of the elegant preferred embodiment 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.
- According to an even further elaboration of the elegant preferred embodiment 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.
- In an additional or alternative even further elaboration of the elegant preferred embodiment 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.
- In an efficient preferred embodiment 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. In addition thereto the partition modules allow for a wide variety of possibilities for composing the optimal acoustic characteristics of the partition system.
- According to another efficient preferred embodiment the partition system according to the invention further comprises strip connecting means for releasably connecting the strips to the partition screens. The same advantages apply as for the partition modules: 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.
- Preferably 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.
- In an optimized preferred embodiment each partition module comprises at least one pair of partition screens interconnected by at least one strip.
- In a practical preferred embodiment each partition screen of a partition module comprises two screen panels alternated by a folding area. Advantageously the panels of each module fold onto each other and adjacent folded modules fold onto each other.
- The invention further relates to a method of assembling a partition system according to the invention, comprising the steps of:
- a) Selecting a first partition module with specific acoustic characteristics;
- b) Selecting a second partition module with specific acoustic characteristics; and
- c) Releasably connecting the second partition module to the first partition module to form the partition screens;
- d) Optionally selecting a subsequent partition module with specific acoustic characteristics;
- e) Releasably connecting the subsequent partition module to the partition screens; and
- f) Optionally repeating steps d) and e) until the partition screens are finished;
- g) Arranging the partition screens on the partition carrier.

Figure 3 schematically shows the twolowest modules 10 of thepartition system 1 in more detail.Figure 3A schematically shows a detailed section offigure 3 .Figure 3B schematically shows a variant of the detailed section offigure 3A . - The partition screen of the
partition module 10 comprises twopanels 3 connected by a folding area. In the embodiment offigure 3A eachpanel 3 comprises several layers: anouter layer 31, aninner layer 32 and anintermediate layer 33 in between. Preferably theouter layer 31 is made of sound isolating material, for instance artificial leather. Preferably theouter layer 31 is made of reinforced material. Preferably theinner layer 32 is made of gauze screen. Preferably theintermediate layer 33 comprises plate like sound absorbing material, like PE or mineral wool. Thefolding area 4 is formed by attaching theouter layer 31 and theinner layer 32 together, preferably by stitching. At both outer ends of the partition module 10 (parts of)zippers 5 are present. The embodiment offigure 3B differs over the embodiment offigure 3A in that it lacks theinner layer 32. Instead thelayer 33 of sound absorbing material is fastened to theouter layer 31. Preferably thelayer 33 of sound absorbing material is directly attached to theouter layer 31, for example by bonding or gluing. Thefolding area 4 is formed at theouter layer 31, more specifically in areas of theouter layer 31 to which nolayer 33 is attached. - Several types of
modules 10 with different acoustic characteristics can be made based on the information disclosed herein. For instance, perforations can be provided in one or more of thepanels 3 in amodule 10. As another example the characteristics of theintermediate layer 32 of eachpanel 3 can be changed. Optionally theintermediate layer 32 can be omitted in one or more of the panels in a module. A tailor-madepartition system 1 can be constructed by a person skilled in the art out of any combination ofpartition modules 10. -
Figure 4 schematically shows a preferred embodiment of a strip orvane 6. Many types of materials are suitable for use in the strips. For instance, the same material that is used for theouter layer 31 of thepanels 3 can be used for the strips. Preferably the material of the strips is a substantially closed material. The length ofstrip 6 is substantially equal to the width of thepartition screen 2. Thestrip 6 is provided with strip connection means 26 along one or both longitudinal sides. Preferably the strip connection means 26 enable releasable connection of thestrip 6 to thepartition screen 2. In the preferred embodiment the strip connection means 26 comprise zippers. -
