IMPROVED DOUBLE ROLLER COVER DEVICE FOR COVERING LAUNDRY HANGING OUT TO DRY.

Description

DESCRIPTION in support of a patent application for MODEL OF UTILITY titled: “Improved double roller blind device for the cover of the laundry hung out to dry” in the name of: CARBONARA Giovanni ------- This innovation concerns a device improved double roller cover for coverage of laundry hanging out to dry. This innovation fits into the field of products whose purpose is to protect the laundry, hung out to dry, from damage due to pheno- atmospheric conditions such as excessive rain and sunshine goes, but also from other damages such as those caused by pollution, i.e. by the deposition of dust and dirt on laundry hanging out to dry. Some types of di- are already known on the market devices that serve to protect laundry from damage listed. For example, there is a commercially available sheet roller blind that can be stretched out to cover the part top of a drying rack where the laundry is hung out dry. In particular, this product is made up of from a waterproof sheet rolled up to form a roll- it, which is mounted on one of the side arms of the- the drying rack and unrolled so that the waterproof sheet meabile covers the top of the drying rack. The free end of the cloth is hooked to the arm- lateral side opposite to the one on which it was mounted rolled up. After use, the cloth is rolled up again around the roller, which is dismantled from the drying rack and put away waiting for the next one use. This type of product has several limitations due to the fact that, once spread out to cover the pan- ni, the cloth appears to be particularly exposed to possible gusts of wind and can wrap itself up same or move, leaving the laundry uncovered, or even come unhooked and fall, with the possibility to cause damage. On the other hand, if the sheet is fixed more securely to the arms of the clothesline, the effect of the wind could cause a tear, or even the complete rupture of the cloth. Furthermore, this type of product covers the hole- to only above, failing to prevent that the laundry hung out to dry on the outermost side of the drying rack is exposed to rain or ray solar diaction. To ensure greater protection of the cover coverage for damage caused by the effect of the wind, as well as ensuring better protection from agents atmospheric and polluting effects of laundry hung out on the side more external than the drying rack, it was proposed secondly I am applying for patent for utility model No. RM2005U000135 in the name of the same applicant, a di- device for covering laundry hung out to dry on a drying rack, which includes a first sheet and a second sheet, wrapped around at least one roller spring, housed on a support frame, called first sheet can be unrolled from said roller spring, called spring roller consequently rolling and causing the unfolding of said second sheet, det- the first cloth and the second cloth can be said to be faces around the same spring roller, or each around a roller, at least one of which is a spring roller, said rollers being connected by a motion transmission system, and in which said te- The laio consists of a casing, inside the which is housed said at least one roller around the which the two cloths are wrapped around, and which can be fixed to the drying rack by means of a duct insertion of a clothesline wire that passes through knows the said frame for its entire length, or through two rings screwed to opposite ends of the said frame, or through two shaped hooks for stable coupling with the opposite arms of the- the clothesline, or through two cable ties wrap around a clothesline wire. The problem with this type of solution is that lies in the fact of having to create a frame that com- necessarily takes a casing, with functions not only for covering the rolled up sheets, but also and so- mainly structural, since it is directly involved in countering the couple that comes to generate between the two ends of the device when unrolling the sheet. Furthermore, in the embodiments that provide for hooking up to the outermost wire of the clothesline, this solution sacrifices the space otherwise available of the last wire of the clothesline for ag- needs device hook. The purpose of this innovation is to provide a device to cover the laundry hung out to dry to dry that is able not only to solve the problems mentioned, but also that it is simple and functional national, with low production costs. It is therefore the specific subject of this innovation a laundry cover device laid out to dry on a drying rack, which includes an upper cloth and a lower cloth, wrapped around no to the same spring roller or two rollers connected in rotation to each other, called upper sheet being able to be unrolled by said spring roller, said spring roller consequently rolling and causing the unfolding of said lower sheet, which includes a support structure of said spring roller, co- constituted by two lateral arms, transverse to each other to the said spring roller, each of which is equipped with an open slit on one side for insertion onto at least one clothesline thread. Preferably, according to the innovation, said side arms feature an angled structure, consisting of a portion for attachment to said wires of a drying rack and a supporting portion of said spring roller. More preferably, according to this inno- vation, said attachment portion has a shape of U, being divided into an upper semi-portion and a lower semi-portion, between which is defined said crack. Furthermore, according to innovation, preferably said support portion has a housing for said spring roller in raised position respect- to the plane passing through said slit. Optionally, always according to this inno- vation, said covering device comprises ul- previously a covering casing of said al- minus a spring-loaded roller, open on one side. This innovation will now be described, illustrative but not limiting title, according to a its preferred form of implementation, with particular reference to the figures of the attached drawings, in which - Figure 1 shows a perspective view of a lateral portion of the bu-covering device laid out to dry according to this innovation tion, in closed position, - figure 2 shows a sectional view of the same so device shown in figure 1, still in posi- closed action, and - Figure 3 shows a perspective view of the same device shown in figure 1, in position open on a drying rack. Referring to the figures, it is shown co- me the covering device 10 according to this innovation consists of a frame, in particular re, in the embodiment shown is constituted with a right side arm 11 and a left side arm 12 left lateral (not shown), between which is dispo- I have a spring roller 12, on which are wound in- together an upper sheet 13 and a lower sheet 14. Preferably, both sheets are made of waterproof material. In cases, like the one in the figure, where around the spring roller 12 has an open casing 15 on one side, when the sheets 13, 14 are completely wrapped around the spring roller 12, of each sheet only one edge is directly reachable that is out- comes out of the 15th wrapper. In particular, the edge of each sheet can be stiffened by one or more rigid splints, in the figures a rigid splint is shown 16 for the upper sheet 13, but being possible to foresee to install one or more rigid splints also for the lower sheet 14. The function of these splints is not only that of keeping both sheets 13, 14 stretched out, but also, as we will see below, that of assi- ensure the correct positioning of the sheets themselves. Furthermore, with regard to the cloth in particular top 13, the function of the splint 16 is also the handle for unrolling the sheet. Both side arms 11 of the device of coverage 10 shown in the figures present a angled structure, consisting of a portion of ag- hook 18 to the wires of a clothesline and a portion of support 19 of the spring roller 12. The portion of the ag- hook 18 has a U-shape, that is, it is divided into an upper semi-portion 18' and an in- semi-portion less than 18”, between which a gap is defined narrow and essentially straight. The terminal part The end of the slit is closed with a zip tie removable closure 20, which embraces the ends of the two semi-portions 18', 18” of the portion of ag- hook 18 of each arm 11 of the device. The support portion 19 has a housing for the spring roller 12. To use the cover device 10 is It is necessary to position it properly beforehand you. This is done by removing the locking strap removable 20 and by forking the two arms 11 of the device positive on the outermost wires 21 of the drying rack, in particular by sliding said transversely outermost wires 21 of the drying rack inside the- the gap defined between the two semi-portions 18', 18” of the attachment portion 18 of each arm 11 of the device. Once the device is positioned 10 cover on the drying rack, applies again the removable closing band 20 on the ends of the two semi-portions 18', 18” of the por- coupling 18 of each arm 11, in this way to ensure the correct sealing of the device 10. When positioning the device 10 it is necessary make sure that the support portion 19 of the roller spring 12 is in a higher position than that of the coupling portion 18 and, consequently, of the threads 21. It should be noted that the application of the device 10 cover on the drying rack not compromising you, if not to a negligible extent, the usability of the 21 wires of the clothesline, not even those of- exactly what is needed for the hookup. After having hung one or more garments on the lines 21 of the drying rack, the sheets 13, 14 are arranged cover. To do this, pull the flap of the upper cloth 13, enough to pass over the wires 21 of the drying rack and cover them. Unrolling the cloth upper 13 causes the spring roller to rotate and the simultaneous unrolling of the lower sheet 14, the which extends downwards, due to its effect same weight, that is, the weight of ballast or battens i- properly housed. In this way, while the cloth upper 13 forms a substantially o- protection horizontal that covers the top of the ste- yes on the drying rack, the lower sheet 14 forms a vertical protection that covers them frontally. Note that the angled shape of the side arms- rali 11 of the covering device 10 allows to keep the spring roller 12 in the raised position with respect to the plane on which the wires 21 of the drying rack, to allow for unfolding of the upper sheet 13 above the wires 21 of the clothes horse toio at a height sufficient not to interfere with the 22 clothes pegs used to secure the laundry to the threads themselves. According to an alternative embodiment, the two sheets 13, 14 can be wrapped around two separate rollers, connected to each other through motion transmission mechanisms, in such a way that the rotation of the upper cloth roller 13, ti- by the user, causes the rotation and unrolling to the upper canvas roller 14. This solution It also allows you to adjust the relative rotation of the two rollers, acting on the transmission ratio, and then adjust the amount of the lower sheet 14 which extends downwards as a result of the extraction of the upper sheet 13, which is arranged above the drying rack. For example, it is possible to provide a mechanism for changing the ratio of transmission that allows, in the event that the indu- clothes spread out on the clothesline are larger in size greater than the transverse ones of the drying rack, to increase the gear ratio so that as a result of the extraction of a certain upper portion of the cloth 13 is extracted a port- larger portion of lower sheet 14. The top sheet 13 must be secured in so as to remain in the lying position. This objective tive can be achieved in several ways. For example, the 16 slats on the outermost edge of the upper sheet re 13 can be made with magnetic material tico, so as to be attracted by a meticulous railing tallica to which the drying rack may have been preceded applied. Optionally, taking into account that the drying racks are not always applied to the rin- rings, on the slats 16 there may be some hooks, which ensure the grip on the railing or, in lack of other supports, to the innermost thread of the drying rack. The preferred solution according to this in- novation provides that on the edge of the upper cloth 13 there are a plurality of slats 16, free of articulate among themselves, so that they can adapt to the different profiles of the different railings. The use of multiple 16 independent magnetic rods It also allows you to modulate the grip force of the upper sheet 13 to the railing. This measure it is necessary to preserve the integrity of the telo 13. In fact, the adjustment of the fixing force the cloth test allows, in case the wind subject the sheet 13 to stresses that could damage it, to establish a stress limit beyond which the magnetic force of attraction which ensures the fixing is exceeded, causing the unhooking of the sheet 13 from the railing and the restart rolling up both sheets 13, 14 on the spring roller the 12. Furthermore, the integrity of the sheet 13 is protected through proper calibration of the spring spring roller 12, which takes into account the material with which the upper sheet 13 is made of. As a consequence of normal wind gusts, or other stresses not excessive actions that tend to pull the cloth up- upper 13, the spring roller 12 will allow the unrolling lament of an additional portion of the upper cloth 13, which is then rewound onto the spring roller 12 not as soon as the solicitation stops. The covering device 10 according to the pre- feel innovation allows you to protect your laundry on two sides (in some cases even three sides), of be permanently installed on the drying rack, to be stretched out with just one simple movement, rewind, avoiding tearing in case of stress excessive wind loads, to cushion the effect of gusts of wind avoiding generating noises due to the stress on the sheet, of rem- always keep it correctly stretched without twisting. yes due to the wind, to avoid the possibility of unhooking and falling of the device. Furthermore, through small adjustments, the covering device 10 according to the present innovation can also be used as needed as an awning. In fact, by coupling the slats 16, 17 of the two sheets 13, 14, so that the edges of sheets 13, 14 are joined, it is possible to ti- move sheets 13, 14 towards the wall or towards the ceiling. to the overlying one, on which they will have previously been suitable anchoring systems are provided, even if gnetic. Furthermore, the device according to this in- novation allows you to avoid sacrificing the last one clothesline wire for hanging needs device, but also to avoid having to interrupt it pears or detach and then reattach for the assembly. More importantly, the device of the This innovation allows to avoid the wrapping outside of the spring roller, which with this solution becomes useless (however non-structural and with func- (simple covering of the sheet), as the couple that is created between the two ends of the device tive is guaranteed by the constraint that the arms can exercise on the wires. Finally, the spring roller (and then the upper sheet) is placed in position raised above the level of the clothesline wires, and consequently the clothes pegs are not an obstacle to the correct unrolling of the top sheet. This innovation has been described at ti- illustrative, but not limiting, purpose, according to its preferred forms of implementation, but it is to be understood that changes and / or modifications may be made by experts in the field without however leaving the relative scope of protection, as defined by the claims attached.
