Definitions

  • the present invention is comprised in the technical field of transportable and reusable acoustic screens.
  • Japanese patent application JP-2006342592-A describes a system made in the form of a framing that can be assembled and disassembled, comprising vertical posts joined together by stringers and cross members between which acoustic screening panels are arranged.
  • the assembly and disassembly of this system which is not height-adjustable, is relatively complex and requires considerable time.
  • German patent application DE-19652871-A describes an acoustic screen applicable to noisy machinery, streets and railroad tracks. It consists of inflatable elements that can be inflated with a gas or filled with a liquid to form an acoustic barrier.
  • the inflatable elements can be assembled with one another to give the assembly the desired shape to insulate the room or the source of noise. Beside the fact that this system is not height-adjustable, folding the hydraulic elements after being deflated is laborious. Furthermore, when inflating, these elements may be rendered useless if they experience mechanical damages that result in air or liquid leaks.
  • Japanese patent application JP-2000248655-A describes an insulating wall system applicable to the inside of buildings under construction. It is also inflatable and adjustable by expansion and contraction of the elements forming it.
  • the insulating wall also incorporates an also inflatable roof and is adjusted to the inside of the building under construction.
  • It is also modular and can be combined with insulating walls. Since it is adjusted to the walls and to the ceiling of the building under construction, not only does it acoustically insulate but it also prevents the transmission of the noise inside the building. The easy assembly and disassembly is also advantageous.
  • This system which is exclusively intended for indoor acoustic insulation suffers from the same drawbacks as German patent application DE-19652871-A .
  • German patent application DE-2948248-A describes an acoustic screen consisting of a folding base which serves as support for a frame and which in turn secures the acoustic insulation unit formed by cassette elements.
  • the screen of the invention is modular and can be combined by means of flexible attachments with other units to cover the desired area under construction or in residential areas.
  • the assembly and transport are simplified since said base is folding, the frame and therefore the acoustic insulation unit is neither height-adjustable nor folding, so it is a drawback in terms of height and the space required for its storage and transport.
  • German utility model DE-29711222-U describes an indoor screen or door which, although it serves as acoustic insulation, also acts as an access door for a room. It can move horizontally and can be wound at one of the sides.
  • the windable door is formed by slats which are unwound, guided by horizontal rails to the end of the profile formed by the frame, where the end of the windable door is hooked. Although it has some similarity with the invention, it is neither transportable, nor folding, nor height-adjustable.
  • DE-3910988-A1 , GB-2380218-A , US-5460462-A , DE-102004033962-A1 and US 2001/006591-A1 disclose free-standing acoustic screening systems comprising a container box and an acoustic screen vertically guided by two vertical side guides anchored to respective side parts of the container box guiding acoustic screen when extending from a lower position in which it is housed in the container box, to an upper position.
  • the object of the present invention is to overcome the drawbacks of the state of the art described above by means of a free-standing acoustic screening system comprising a base, an acoustic screen and side profiles for the acoustic screen, wherein the base is a container box, the acoustic screen is vertically extendable from a lower position in which it is housed in the container box to an upper position, and the side profiles are two vertical side guides anchored to respective side parts of the container box in which the acoustic screen is guided in its movements between said lower position and said upper position characterized in that it comprises a ridge board comprising a vertical plate coupled at the top portion to said side guides and in which ridge board at least one side wing that can be unfolded towards a horizontal plane is articulated.
  • the acoustic screen can be made of a material with acoustic insulation capacity that can integrate a transparent or translucent material to allow light in and/or to prevent the effects of a boxed-in feeling for people and/or to allow the screened acoustic source to remain visible.
  • the acoustic screen is windable about a winding shaft.
  • the acoustic screen can be formed by horizontal rows of windable slats and joined together like a blind extending between said side guides, by a flexible material windable around a winding shaft, or by rows of strips in a staggered arrangement joined together by means of horizontal shafts, at least one of said horizontal shafts being able to be guided in said side guides in the latter case.
  • the container box can be provided with an upper cover with a groove extending between said side guides and sized to allow the passage of the acoustic screen.
  • the winding shaft can suitably be connected to a winding mechanism for winding the acoustic screen when the latter drops from its upper position to its lower position.
  • the side guides can comprise respective C-shaped curved upper sections performing the function of an acoustic ridge board.
  • the acoustic screen is formed by horizontal rows of folding slats articulated to one another by means of horizontal shafts guided in said side guides and by means of respective second horizontal shafts shorter than the first horizontal shafts and which are not guided in the side guides, such that two folding slats articulated to one another by means of one of the second horizontal shafts are arranged between every two of the first horizontal shafts.
  • the acoustic screen is formed by horizontal rows of folding slats articulated to one another like a bellows by means of horizontal shafts guided in said side guides and by means of respective second horizontal shafts shorter than the first horizontal shafts and which are not guided in the side guides.
  • Each first horizontal shaft is coupled to a first side slat and to a second side slat, whereas two first folding side slats and two second folding side slats articulated to one another respectively by means of one of the second horizontal shafts are arranged between every two of the first horizontal shafts.
  • the container box can comprise an upper cover with a passage opening extending between said side guides and sized to allow the passage of the acoustic screen.
  • the container box can furthermore be provided with at least one hatch cover blocking the passage opening and is articulated to said upper cover such that it is pushed upwards by each folding slat, which moves towards said upper position of the acoustic screen.
  • the acoustic screen can be coupled to an upper horizontal securing bar that can be immobilized at least at one height and preferably at different heights in said side guides by means of an anchoring system.
  • This anchoring system can be comprised by bolts traversing respective holes in the side guides and entering respective cavities in the ends of the securing bar.
  • the system comprises an additional acoustic screen with some or all of the features of one of the embodiments of the invention defined above in this specification.
  • the ridge board can comprise at least one side wing that can be unfolded towards one side of the vertical plate and at least one side wing that can be unfolded towards the other side of the vertical plate.
  • the ridge board contributes to the acoustic screening and preferably at least one of its wings is coupled to the vertical plate by means of supporting elements which allows regulating the degree of inclination of the wing with respect to the vertical plate.
  • at least one of the side wings can comprise an articulation such that they can be regulated.
  • the container box can be coupled to side or axial counterweights and/or comprise respective side compartments to house a counterweight material and/or respective axial compartments for housing such counterweight material.
  • the counterweight material can be sand, water, construction material, gravel, etc.
  • the container can have an upper hatch system for filling the compartments and a lower or side hatch system facilitating their subsequent unloading.
  • the container box comprises coupling means for coupling it with at least another container of an acoustic screening system with the features indicated above in this specification.
  • the screening system can be easily transported, assembled and disassembled while at the same time it is effective for mitigating the noise from construction work, public entertainment events, etc.
  • the system Due to its free-standing capacity (not requiring foundation), the system is ideal for urban settings, and the possibility of modifying its height allows assuring its efficacy without requiring excessive approximation to the source of noise which may interfere in the operation thereof, and in the case of construction areas, have an effect on safety aspects. Its fast assembly and disassembly allow it to be adapted to the movements of sources of noise with a short duration.
  • Figure 1 shows a general embodiment of the free-standing acoustic screening system in which the latter comprises a container box -1-, an acoustic screen -2- vertically extendable from a lower position in which it is housed in the container box -1- to an upper position (shown in Figures 1-3 ) and two vertical side guides -3- anchored to respective side parts of the container box -1- in which the acoustic screen -2- is guided in its movement from the lower position to the upper position.
