    Manual and portable device for winding and dehydrating flat hoses. Field of the Invention
    The present invention belongs to any field that uses flat hoses, such as the field of civil engineering, the field of maritime engineering or the field of aerial engineering; and more specifically to any field that uses flat fire hoses for firefighting practices and firefighting, such as industry in general (industries, commercial businesses, public spaces) or transport sectors such as: maritime industry (on board ships in fishing and recreational vessels and in port facilities), the air industry (fire services and airport facilities) and road and rail transport. Background of the invention
    At present, flat hoses have great utility in all productive sectors of society, due to their rapid operation of use and the little space they occupy for storage. Specifically, flat fire hoses identify a type of flexible pipe that is used to transport pressurized water from the water supply to the place where it must be discharged to extinguish a fire or cooling in an abnormal heat source, either to do a fire training exercise or to quell a real fire, and it is performed by a fire department or firefighting personnel trained in a facility.
    The collection of flat hoses is done manually after use, with several manual winding and dehydrating techniques.
    Two of the most used techniques consist of:
    a) Perform the winding and at the same time emptying the water that is inside the flat hose (dehydrated), starting from half its length towards the ends of the flat hose, where the fittings are located. This winding technique is usually used primarily to wind flat hoses, and in particular flat fire or small diameter fire hoses.
    b) Perform the winding and dehydration of the flat hose, starting from tulle fitting (end) until the hose can be rolled up to the other fitting (the other end). Specifically, this technique is often used to wind flat supply or large diameter fire hoses.
    Note that once the flat hoses have been used they have fluid inside (water in the case of flat fire hoses), so to empty the hose (dehydrate the hose) you have to depressurize the fluid supply (close the water supply in the case of flat fire hoses), loosen the connection fittings of the flat hose and proceed to bending it on itself so that the fluid (water in the case of flat fire hoses) comes out of its interior ( dehydrated). In any case, and for any of the two techniques described, at least two people are normally needed and the work is uncomfortable, manual and slow. In addition, for manual winding it is necessary to be trained and it takes an average time of five minutes to wind up each section of flat hose, either supply hoses (large diameter) or attack hoses (small diameter).
    Specific. the winding of a flat fire hose is vital to act effectively and promptly before a fire, since when they unfold, the hoses must be able to connect to each other through their fittings, without getting entangled and flowing the water easily inside, and everything (its unfolding and use) must be produced in a comfortable, fast, efficient and simple way.
    In addition, sometimes being able to arrange, during a fire (in an industrial, commercial, on a ship or in a port, airport or railway installation) the hoses that have been used in the suffocation of a spotlight in a fire and move them To reinforce and extinguish another open focus, it depends on its winding and the speed with which these hoses can be moved. This can have an impact on saving people and evacuating them before a fire and managing to protect and save the facility itself from the flames or lose it before the fire.
    As already mentioned, flat fire hoses have two categories with respect to their diameter and use. What are they:
    -  Supply hoses or also called large diameter, measure between 2.5 inches and 5 inches (6.35 centimeters and 12.7 centimeters) in diameter and are used as supply lines that connect to fixed hydrants or pump trucks of supply. When these hoses are loaded (pressurized with water) they are very heavy to move (they need at least five people to drag them) and are difficult to bend for proper stowage.
    -  Attack or small diameter hoses. which have a diameter between inch and 2.5 inches (2.5 centimeters and 6.35 centimeters). These hoses are the ones used as attack lines, they are also known as hand lines. At its end is where the spear or python is placed to quell fires or thermal bulbs. They retain their flexibility when loaded and are easily managed by a team of two or three firefighters as they move through the interior spaces of a building, vessel or fishing or recreational vessel, port installation, airport installation road transport and in rail transport devices.
    As for the size (length) of the flat fire hoses by international rules standards, nominally referred to the American Fire Regulations (NFPA Standards 1961, 2007 edition) the sections of flat fire hoses are 60 feet (18 feet) , 30 meters). But at present, depending on its manufacturing location, this length varies between 15 meters to 30 meters (50 feet to 100 feet), so that it can be easily manipulated and at the same time replaced easily, quickly, efficiently and easily. .
    The document "US2014 / 0374528A1 Power-assist fire hose reel", presents a reel that needs a base to pivot and wind the hose, and the driving force of the reel can be produced by an electro-mechanical device (a battery drill) or annexing an annex system formed by a rod for manual winding. The system is designed to work together and does not present immediate portability.
    The document "US06925692 Hose storage apparatus", presents a cart equipped with wheels for portability, in which the hoses are introduced, and by means of a crank fitted in a drum it is rolled up. This ingenuity presents a notable problem of immediate use of flat fire hoses, since its bending around a drum does not make its launch feasible for subsequent installation of fittings, easily and quickly, characteristics that must be assembled to A correct action before the fire.
    Therefore, and in view of the state of the art, it can be concluded that current winding systems for flat hoses, and in particular flat fire hoses, do not allow winding and dehydration independently, portable and fast. either of the two forms of winding for said hoses, which are used in the industry in general (industries, commercial businesses, public spaces); and in the transport sectors such as: the maritime industry (on board ships, in fishing and recreational vessels and in port facilities), the air industry (fire services and airport facilities), and road transport and by rail.
    Specifically, the systems described have limitations in some of the winding parameters or are designed for specific and static industrial systems, not for winding in case of eventualities (emergencies) in the event of fire intervention or for the performance of usual practices in fire matter by civil fire departments. Military, ship crews or operators of port facilities, air installations and do not do it comfortably, quickly, efficiently and easily. Summary of the Invention
    The present invention seeks to solve the aforementioned drawbacks by means of a manual and portable device for winding and dehydrating flat hoses, preferably flat fire hoses, comprising:
    -  a rod configured so that, during operation of the device, it rotates on the base of the rod, such that said rod base has a spherical machined shape, and acts as the axis of rotation of the entire device, where the rod has at least three sections, a) a lower section between the base of the rod and a lower bending point, whose axis - main axis - is vertical during the use of the device, such that during the use of the device the user grabs with one of its hands this lower section at the top; b) an upper section between the upper part of the rod and an upper bending point, whose axis is parallel to the main axis, such that the upper and lower bending points do not coincide, and such that during the use of the device the user grab this upper leg with your remaining hand; and c) at least one intermediate section between the upper and lower bending points, configured so that during the use of the device, the user can freely rotate the device for winding a flat hose without tripping over any part of its body;

    or two teeth, and such that in the case that the device comprises more teeth, these are not used although they allow the user to clamp the flat hose with less effort: then, the user grasps the upper part of the inner section with one hand. the rod holding the hand -and the arm-, and on the other hand, grasps the upper section with the remaining hand, moving the hand and arm circularly so that in this upper section a manual driving force is produced.
    In a possible embodiment, the rod has three sections: the lower section, the upper section and a single intermediate section whose axis has an angle between 19 and 25 degrees with respect to the main axis.
    In a possible embodiment, the rod is compact and has no joining pieces for use, presenting bends at the bending points, such that said bends are made during the manufacturing process, in order to guarantee its structural rigidity.

    In this text, the term "comprises" and its variants should not be understood in an exclusive sense. that is, these terms are not intended to exclude other technical characteristics, additives, components or steps.
    In addition, the terms "approximately", "substantially", "around", "ones", etc. should be understood as indicating values close to those terms accompanying them, since calculation or measurement errors result impossible to get those values with total accuracy.
    In addition, in the context of the present invention, flameproof material is understood as that material that is not capable of causing sparks or thermal source when used.
    In addition, in the context of the present invention, fittings are understood to mean metal or composite elements that have flat hoses at their ends so that they can be spliced (lengthen the length of the hose). In addition, flat hoses when they are complete, that is, with a fitting at each end, are also known as racoradas hoses. The fittings have the characteristic of being symmetrical, that is, that any fitting connects with any other of its kind. In this way, the most commonly used hose fittings nationally and internationally, such as the Barcelona model fitting, fit the same diameter fittings and the NH fitting. NFPA USA (mainly used in fire fighting systems in the USA) do so with all of the same diameter. The present invention works with any type of fitting, since the work of winding and dehydrating is independent of the type of fitting or joining system of flat hoses.
    The characteristics of the device of the invention, as well as the advantages derived therefrom, may be better understood with the following description, made with reference to the drawings listed above.
    The following preferred embodiments are provided by way of illustration. and are not intended to be limiting of the present invention. In addition, the present invention covers all possible combinations of particular and preferred embodiments indicated herein. For those skilled in the art, other objects, advantages and features of the invention will be derived partly from the description and partly from the practice of the invention.
    Next, the manual and portable device of the invention for winding and dehydrating flat hoses is described, in a straight, fast, efficient and simple manner, according to the scheme thereof of Figure 1. The device is configured to fit all flat hoses, such as flat-line supply fire hoses or large diameter calls measuring between 2.5 and 5 inches (6.35 centimeters and 12.7 centimeters) in diameter; and the flat hoses of attack fire or small diameter, which have a diameter between 1 inch and 2.5 inches (2.5 centimeters and 6.35 centimeters).
    The device 10 comprises a rod 11 configured so that, during the operation of the device 10, it rotates on its base 11D and acts as the axis of rotation of the whole assembly, performing the winding and dehydration of the flat hoses. The base of the rod 11D has a spherical machined shape that allows it to rotate without difficulty.
    The configuration of the rod 11 has at least three sections, such that there is a) a lower section 11A between the base of the rod 11D and a lower bending point 11E, whose axis (main axis) is vertical during the use of the device 10, and such that during the use of the device 10 the user grasps with one of his hands this lower section 11A by its upper part: b) an upper section 11B comprised between the upper part of the rod 11 and an upper bending point 11F , whose axis is parallel to the main axis, such that the upper 11F and lower 11E bending points do not coincide, and such that during use of the device 10 the user grasps this upper section 11B with his remaining hand; and c) at least one intermediate section 11C between the upper 11F and lower 11E bending points, configured so that during use of the device 10, the user can freely rotate the device 10 for winding a flat hose without tripping over any part from his body. Thus, during operation of the device 10 of the invention, the user keeps the hand (and arm) that grabs the lower section 11A fixed, by circularly moving the hand (and the arm) that grabs the upper section 11B, such that in this upper section 11B a manual driving force is produced.
    Preferably, and as shown in Figure 1, the rod 11 has three sections: the lower section 11A, the upper section 11B and a single intermediate section 11C whose axis has an angle preferably between 19 and 25 degrees with respect to the main axis .
    Preferably, the rod 11 is compact and has no joining pieces for its use, presenting bends at the points defined above 11E, 11F, such that the bends are made during the manufacturing process, in order to guarantee their structural rigidity.
    In a possible embodiment, the material of the rod 11 is metallic and flameproof, in this case being preferably alloyed with bronze at its origin. In another possible embodiment, the material of the rod 11 is plastic or composite material such that its rigidity and minimum torsion are guaranteed during the work of winding and dehydration (when the tractor 10 has more tractor load).
    Preferably, the rod 11 comprises two handles 12A, 12B configured to hold the device 10 in order to perform the winding maneuvers with the hoses manually, the first handle 12A is located at the top of the lower section 11A, just before of the lower bend (11E), while the second handle 12B is located at the top of the rod 11; the longitudinal axes of the handles 12A, 12B being therefore parallel to the main axis of the rod 11. In addition, both handles 12A, 12B are preferably rotatable and ergonomically adaptable to any type of hand, even wearing firefighter equipment gloves, being preferably non-slip and insulating material preferably constructed with plastic material.
    As Figure 2 shows, the device further comprises at least two teeth 23, preferably two, in the lower part of the lower section 21A of the rod, such that the teeth 23 are equidistant from the rod, and such that the teeth 23 have a separation of 360º / number of teeth from each other, considering the axis of rotation as the axis of rotation.
    The teeth 23 can be made of cast iron or added by welding or glued to the rod. In any of the cases, the tooth 23 joins the rod perpendicularly and in turn has a curved 23A towards the base of the rod 21D whose angle is between 75 ° and 95 °. In one possible embodiment, the bending 23A of each tooth 23 has an angle of 90 °, such that the teeth 23 and the rod are parallel to each other. In addition, to be able to perform the winding in a comfortable, fast, efficient and simple way, it is necessary that there is a measurement gap between the base of the rod 21D and the base of the tooth 230 of at least 1 centimeter, preferably two centimeters.
    The base of the teeth 230, preferably has a rounded shape (blunt), so as not to damage the hoses during winding and dehydration. These teeth 23 allow, by design, to adapt to wind different types of flat hoses, for example, with diameters of 1 inch (2.5 centimeters) or 5 inches (12.7 centimeters). In any case, a person skilled in the art will understand that the use of hoses of different diameter will depend on the length of the teeth 23 between their bent 23A and their base 230, for example in the case of flat hoses with a diameter of 2.5 centimeters. (12.7 centimeters) it might be appropriate to work with tooth lengths of 6 centimeters (15 centimeters).
    The material of the teeth 13, 23 is of the same constructive characteristics as the rest of the rod 11, being able to be made of metal alloyed with bronze so that they are non-slip, or of plastic, or composite material, but always guaranteeing their torsional rigidity to function as Comfortable, fast, efficient and simple way.
    Figures 3, 4 and 5 show different views of the device by winding a flat hose 34, 44, 54. The teeth 33, 43, 53, configured to wind the flat hoses 34, 44, 54, allow winding from one end of the flat hose 34, 44, 54, one of the fittings acting as origin (Barcelona model fitting. or NR NFPA USA model. or any other type of connecting hose or bypass of flat hoses 34, 44, 54) of the flat hose 34, 44, 54 (this mode of winding is normally used in the supply hoses or also called large diameter) or, from half the length of the flat hose 34, 44, 54, to finish winding and dehydration with the fittings on the periphery of the flat hose 34, 44, 54 rolled up (this winding mode is normally used in attack hoses or also called small diameter).
    The use of the device 10 of the invention during its operation is as follows: the user places the device 10 such that the flat hose 34, 44, 54 is imprisoned by means of the base of the rod 11D, 21D and one or two teeth 13 , 23, 33, 43, 53 (in the case that the device 10 comprises more teeth 13, 23, 33, 43, 53, these a priori will not be used; however, there are three or four teeth 13, 23, 33, 43, 53 allows the user to clamp the flat hose 34, 44, 54 with less effort). Then. the user grabs the upper part of the lower section 11A, 21A, 41A of the rod 11, 41 (if necessary, by its handle 12A, 32A, 42A) with one hand holding the hand (and arm), and by on the other hand, grasp the upper section 11B, 31B, 41B with the remaining hand (if applicable, by its handle 12B, 32B, 42B), moving the hand (and arm) circularly so that in this upper section 11B, 31B , 41B a manual driving force is produced. The axes of the lower sections 11A, 21A, 41A and upper sections 11B, 31B, 41B must be vertical. Thus. The device 10 of the invention allows winding and dehydration of flat hoses 34, 44, 54 in a comfortable, fast, efficient and simple manner.
