Definitions

  • the subject of this invention is a mosquito-net with net-guiding chain driving device for net with horizontal sliding.
  • the invention finds particular even if not exclusive application in the field of components and accessories for frames, as mosquito-nets for preventing insects from entering inside conventionally inhabited places, for example houses and offices.
  • the mosquito-nets can be usually put into two categories.
  • a second, indicated as mosquito-net in assembly kits, is that much more common on the market.
  • roller shutter box of the type generally given by a profile or extruded aluminium bar, on the inside of which is coaxially inserted the mosquito-net roller.
  • the roller may also include one corresponding preloaded return spring.
  • the ends of the roller shutter box they are normally closed by suitable plates, or better heads, which are supplied in two versions, fixed or with counter-plates or caps which are adjustable.
  • a shielding device comprising a foldable shield having a base side, a left-hand side and a right side, the shield extending longitudinally between a left-hand frame element extending upwards and a right-hand frame element extending upwards, longitudinally movable the one with respect to the other in order to open the foldable shield, the apparatus including moreover a top guide element extending longitudinally and an base guide element extending longitudinally, each guide element being flexible and bent in a cross direction adjacently to one of the left-hand and right-hand frame elements so as to present a free end that moves downwards and upwards as regards one of said left-hand and right-hand frame elements when the shield is opened or closed, each guide element having flexing elasticity determining an elastic return force, characterised in that the free ends of each guide element slides along one of said left-hand or right-hand frame elements, in that the other end of each guide element is fixed to the other one of the left-hand and right-hand frame elements, and in
  • EP 999335 (Metaco ) describes a shielding device including:
  • a flexible guide structure made up of a number of rigid units pivotably connected one after another by means of pins.
  • the guide structure engaged in a slidable way along a fixed section, presents an end fixed on the movable stanchion and an end section sliding and guided along a shaped prolongation of the section.
  • the guide structure therefore maintains a rectilinear development in the section extracted from the fixed stanchion, and flexes at the input opening in the stanchion to be housed and extracted from the same in accordance with the opening and closing movements of the curtain.
  • the represented screen solutions all aim to contain, if not apparently eliminate, the visual impact of horizontal and parallel guides that are usually placed along the horizontal levels that delimit, on the upper and lower part the architectonic opening to be closed with said protective screen.
  • the represented solutions are not able to minimize in an effective way the sizes of guides where present, with an aesthetic aspect that results in conclusion little acceptable.
  • the mechanisms are not particularly efficient in allowing for smooth screen movement, thus not guaranteeing linear sliding and the correct tension of the net.
  • the illustrated solutions seem constructively complex, not easily manufacturable also due to the presence of a large number of codes that complicate warehouse management.
  • the aim of this invention is also to avoid the above-mentioned drawbacks.
  • a first and unquestionable value as regards the conventional mosquito-nets, consists in the fact that the mosquito-net does not have a lower guide, and in any case, for particularly wide openings, can provide also a guide but that however has an extremely contained thickness. Under the practical profile, when the mosquito-net is not pulled out, that is, the net is wound on the corresponding roller, it is not visible or significantly visible, along the lower plane of the architectonic opening to be closed, any element that can be little aesthetically acceptable and obstacle to the free transit of people and things.
  • the prevision of the roller, inside the roller shutter box allows for a persistent yet light tension on the net, which, when pulled out offers greater guarantee of effectiveness against intruding insects, and simultaneously the tenseness remains uniform and particularly resisting to the deformations also with insistent pressure on the surface of same, e.g. because of a faster air circulation
  • the movement of the handlebar is smooth and easy requiring only slight effort from the user.
  • One more aim is that the assembly and vice-versa of the mosquito-net is more effective and noticeably comfortable, the roller shutter box is contained dimensionally, favouring housing in the narrow seats and as a whole with less visual impact.
  • the mosquito-net 1 a, 1b, 1c, and 1 d includes a lateral and vertical roller shutter box 10, on the inside of which there is a roller and a relative net or screen, with a first end joined to the said roller and around which it is wound to be turned exiting sideways from said roller shutter box 10.
  • the roller in one case, has a helical charging spring, that is fixed with one end to said roller, in such a way that, turning the net, the roller also turns involving the charging by twisting of the helical spring, not illustrated, and the consequent tension of the net.
  • a fixed horizontal upper guide 20 with two ends 200, 201, respectively right and left, is joined to the vertical roller shutter box 10, along which a vertical handlebar 30 is longitudinally movable, in and out, that is perpendicular to said fixed guide 20.
  • a first end 400 of the net guiding chain 40 is fixed which consists of a series of rigid modules 41, reciprocally hinged, where the length of the net guiding chain 40 is at least equal to the width of the opening to be closed by means of the installation of the mosquito-net 1a, 1b, 1 c, and 1 d.
  • the second end 401 of the net-guiding chain 40 slides in a controlled way inside the handlebar 30 that is substantially hollow. More particularly, the second end of the net is engaged to the handlebar 30.
  • the first end is engaged to the roller of the roller shutter box 10, in such a way that moving the handlebar 30 the contextual winding-unwinding for distending the net and the sliding inside the handlebar 30 of the net-guiding chain 40 takes place.
  • the lower border longitudinally remains inside the profile of the modules 41 of the net-guiding chain 40.
  • the driving movement of the net-guiding chain 40 is controlled by a device essentially made up by two ropes
  • the first 50a has its end 500a engaged at the end 201 of the fixed guide 20 and by means of a pulley 60 hinged at the upper end 31 of the handlebar 30 transmitted along the handlebar 30 to be fixed with the head 501 a to the head module 41 of the net-guiding chain 40.
  • the rope 51 a is engaged with the end 510a to the end 200 of the fixed guide 20, at the opposite side with respect to the first 50a and transmitted by means of the pulley 61 hinged at the upper end 31 of the handlebar 30 downwards, along the handlebar 30.
  • a second driving device solution of the net-guiding chain 40 of the type with two ropes 50b and 51 b is shown. More particularly, it comprises essentially of a rope 50b that is with the end 500b engaged at the end 201 of the fixed guide 20 and transmitted by means of a pulley 60 hinged at the upper end 31 of the handlebar 30, downwards, along the said handlebar 30 to be fixed with the head 501 b to the head module 41 of the net guiding chain 40.
  • the second rope 51 b is engaged with the head 510b at the upper end 31 of the handlebar 30 to horizontally protract along the fixed guide 20 until it intercepts the gear-wheel 70 placed at the end of the roller or a part of the same contained inside the roller shutter box 10.
  • the rope 51 b is characterised by ball-like elements 520, that engage the gear-wheel 70, in such a way as to prevent sliding, by overcoming the resistance to the rotation that is exercised by the helical spring, not illustrated, that cooperates with the roller placed in the roller shutter box 10.
  • the head 511 b of the second rope 51 b that originates from the gear-wheel 70 is transmitted by means of the pulley 61, hinged at the upper end of the handlebar 30, downwards along the handlebar 30, in order to be transmitted upwards by means of the pulley 62 that is hinged below at the handlebar 30, and then again transmitted downwards turning around the pulley 63 joined to the head module 41 of the net-driving chain to finally be fixed in the lowerside 32 of the handlebar 30.
  • the mosquito-net 1 c shown in figure 3 is configured as a third driving device solution of the net guiding chain 40. It is a mono-rope device 50c whose head 500c is engaged at the end 201 of the fixed guide 20 and transmitted by means of the pulley 60 hinged at the upper end 31 of the handlebar 30, downwards, along said handlebar 30, to engage at the lower end 32 a gear-wheel 80 that transmits the rope 50c upwards along the handlebar 30.
  • the rope portion 50c that originates from the gear-wheel 80 is then sent along the fixed guide 20, by means of the pulley 61 hinged at the end upper 31 of the handlebar 30, so that the second head 501 c fixes at the end 200 of the fixed guide 20.
  • the movement of the handlebar 30 on the horizontal-plane involves the rotation in one or in the other way of the gear-wheel 80, which peripherally assures on the upper and countershaped profile of the net guiding chain 40, determining its deposition and vice-versa. Also in that case, so as to avoid the sliding of the rope 50c, at least one portion of the same is made of elements 520 which are able to engage said gear-wheel 80.
  • the mosquito-net 1 d of figure 4 relates to a fourth driving device solution of the net guiding chain 40. Also in this case, it is a mono-rope device 50d whose head 500d is engaged at the upper end 31 of the handlebar 30 and transmitted by means of the pulley 64 hinged at the end 201 of the fixed guide 20, along said handlebar 30. More particularly the rope 50d, that originates from the pulley 64 is sent towards an additional pulley 60 hinged at the upper end 31 of the handlebar 30 that provides for the transmission of the rope 50d towards the lower end 32 of the handlebar 30, where it engages a gear-wheel 80 also of the reduction type.
  • the gear-wheel 80 transmits the rope 50d upwards, along the handlebar 30 to turn around the pulley 61, hinged at the upper end 31 of the handlebar 30. From the pulley 61, the rope 50d protracts along the fixed guide 20, until the end 200, where it intercepts the gear-wheel 70 positioned at the end of the roller or a part of the same contained inside the roller shutter box 10 like for mosquito-net solution 1d, and then with the head 501 d that turns around the gear-wheel 70 to be transmitted to the end 31 of the handlebar 30 where it is fixed.
  • At least one part of the rope 50d is characterised by elements 520 that engage the gear-wheel 70, in such a way as to prevent the sliding, by overcoming the resistance to the rotation that is exercised by the helical spring, not illustrated, and that cooperates with the roller placed in the roller shutter box 10. Also in this case, the movement of the handlebar 30 on the horizontal-plane involves the rotation of the gear-wheel 80 in one or in another way, which peripherally assures on the upper and countershaped profile of the net guiding chain 40, determining its deposition and vice-versa.
