Definitions
- the present invention relates to devices for delivering a fluid, liquid or gaseous, with different distances from the fluid source.
- the invention refers to an extensible device for delivering a fluid, for instance waterworks water, for the domestic irrigation or in greenhouse, or in connection to a hydro-polishing machine for washing or for domestic and industrial cleaning.
- a fluid for instance waterworks water
- a hydro-polishing machine for washing or for domestic and industrial cleaning.
- the device also allows the deliver of gaseous fluid such as compressed air.
- the main drawback of the known means consists in their reduced ergonomics and practicality caused by their encumbrance and weight and also by the fact that the hoses of the known means have the tendency to twist, blocking the passage and interrupting the liquid flow and causing the delivery interruption.
- a further drawback consists in the fact that the hoses of the known means generally do not withstand for long time the hydrostatics pressure of the waterworks and therefore the liquid flow in pressure can not be interrupted in correspondence of the dispenser end but it must be interrupted by means of a faucet connected to the opposite end, otherwise hose bursts and uncontrolled losses of liquid, harmful and expensive, may happen.
- Another drawback consists in the difficulty and the time needed for storing the known means whose hose must be picked in free coils or wound around a coiler; this latter partially makes easier the retraction of the hose but increases the encumbrance and the general weight of the known means.
- the main object of the present invention is to propose an extensible device to deliver a fluid that is extremely easy and comfortable to be used, of small encumbrance and weight and therefore ergonomic.
- a further object is to propose a device that does not cause interruptions of the fluid flow and the job because of folding, narrowings or similar.
- Another object is to propose a device withstanding for indefinite time pressures up to over 10 bar and therefore also allowing the flow interruption at the delivery end of the device even during the non-operating periods and also preventing uncontrolled losses of fluid in case of cut or bursts of the same device.
- Further object is to propose a device that can be stored in orderly coils, of very small dimensions when not extended and that has a pleasant aesthetical aspect.
- FIG. 1 shows a schematic axonometric view of the device object of the present invention to including a fitting in a connection condition with a liquid source;
- FIG. 1 shows longitudinal section views of a fitting body of the device of figure 1, having respective variants of the valve means and the connections of the device, in which some parts have been removed for better underlining the others;
- figures 8 and 9 show partial section side views of respective variants of the device of figure 1 ;
- figure 10 shows a top view of a variant of the device of figure 1 ;
- FIG. 11 A and 1 IB show respectively a side view and a top view of a variant of the device in a retract and extended conditions
- the figures 12A and 12B show corresponding views of a variant of the device of the figures 11 A and 1 IB.
- numeral 1 indicates the extensible device for delivering a fluid including a coiled hose 2 in plastic material.
- the coiled hose 2 is made of at least one among the following materials: Polyamide PalO or Nylon 6, Polyamide Pall, Pal2 or Rilsan, Polyurethane, Polyethylene, Polypropylene PP, Polyester and Poly vinyl Chloride PVC.
- the coiled hose 2 can be realized with the coextrusion technique having two concentric layers both made with said plastic materials.
- the hose 2 can be realized including a layer of composite material containing strengthening fibers, for instance fiberglass or synthetic fibers; the hose 2 can further be knitted-reinforced.
- the hose 2 has a spiral helical shape, that means with coils of equal diameter hold in a thigh cylindrical surface configuration. In absence of solicitations, the hose preserves or takes back the spiral helical shape because of the elasticity and the memory of said material.
- the coils of the hose 2 are extended and stretched out when the two ends of the hose 2 are spread apart.
- the coiled hose 2 has, for instance, an inside diameter between 5 and 13 mm, an outside diameter between 7 and 15 mm and a wall thickness between 0,5 and 1,5 mm.
- the preferred dimensions of the inside and outside diameters of the hose 2 are respectively about 6 mm and 8 mm or 12 mm and 14 mm.
- Said coiled hose 2 is fit to withstand inner pressures even higher than 10 bar.
- a first fitting 3 is fixed to an end of the hose 2 for a source of liquid in pressure, for instance a faucet or an intake connected to the public waterworks or to a pressure reservoir containing for instance a liquid solution for treatments or detergent.
- the other end of the hose 2 has a second fitting 4 for instance for an adjustable flow dispenser 5 for delivering the source liquid.
- the fittings, first 3 and second 4 are of quick clutch type used in the hoses for manual irrigation. It is also provided that the fittings, first 3 and second 4, can be fixed or semi-fixed type with plastic hoses such as those used in the watering plants or in the waterworks.
- the first fitting 3 includes a removable connection 24 having a threaded portion for sources like faucets or connections with threaded intake.
- the second fitting 4 has a device of the type so-called water-stop, known and not shown, fit to interrupt the liquid flow in correspondence of a removal condition of the dispenser 5.
- the fittings, first 3 and second 4 include each a body 7 having a clutch portion 25 for the hose 2.
- the clutch portion 25 has a longitudinal hole 12 for a duct 31 of the liquid flow F flowing from the liquid source to the dispenser.
- Valve means 6 are associated to the first fitting 3 for stopping the liquid flow F when overcome a predetermined threshold.
- the valve means 6 include a rod 15 sliding in the duct 31 and having in correspondence of its ends a first head 11 and a second head 26 mating respectively stop means first 13 and second 28 carried out in correspondence of the end of the duct 31.
- the valve means 6 include elastic means 9, consisting for instance in a conical helical spring, positioned between the first head 11 and a stop housing 10 of an end of the elastic means 9 so working in compression.
- the housing 10 is carried out downstream the first stop 13 with respect to the flow F.
- the heads, first 11 and second 26, prevent the unthreading of the rod 15 from the duct 31 and the first head 11 realizes a hydraulic seal when mating the first stop means 13.
- the first head 11 can have a gasket for the watertight seal.
- the second head 26 has sealing means 29, for instance an annular gasket, in order to prevent the backflow when these latter mate the second stop means 28.
- the shape of the second head 26 advantageously realizes a liquid check valve whose presence, obligatory by law in several countries, is always advantageous in order to avoid, for instance, the eddy of contaminated water into the waterworks.
- the connection between each end portion of the coiled hose 2 and the relative fittings first 3 and second 4 is realized by means of the insertion of the clutch portion 25 into the respective end portion of the coiled hose 2.
- Said end portion is inserted into a tubular element 33 fit to increase the total thickness of the end portion of the hose 2 for allowing its blocking in the usual quick fittings for manual irrigation that are standardized for hose having a thickness greater than the thickness of the coiled hose 2.
- the tubular element 33 can have the same length of the clutch portion 25 or can be, for instance, up to 10 times longer. In this last case the tubular element 33 also protects and strengthens the hose 2 in proximity of the fittings first 3 and second 4. It is provided that the tubular element 33 has at least a cylindrical portion and a portion tapered with thickness progressively decreasing with the distance from the fitting.
- the operation provides that, after the connection of the device 1 to the liquid source, for instance a faucet or the high-pressure connector of an hydro-polishing machine, the user operates the dispenser regulating manually the direction and the flow rate of the spout.
- the liquid source for instance a faucet or the high-pressure connector of an hydro-polishing machine
- a tubular block mean 30 having unthreading mean 32 consisting of, for instance, annular nicks, in order to prevent the unthreading of the block mean 30 from the end of the hose 2 and the unthreading of this latter from the fitting first 3 and second 4.
- unthreading mean 32 consisting of, for instance, annular nicks
- an end of the hose 2 is connected to the respective fitting first 3 and second 4 according to the variant joint of figure 3 and the other end is connected in the way shown in figure 2.
- the variant of figure 4 refers to a valve mean in which the compression of the elastic means 9 is adjustable in order to vary the intervention threshold of the valve means 6.
- the housing 10 consists of a flat side of a tubular cylindrical mean 40 externally threaded for the fixing to a corresponding threaded portion 14 of the hole 12.
- the rod 15 pass through the tubular mean 40 which has internally a set of longitudinal slots 16 engaged by the rod 15, having for instance cross-shaped section.
- the first head 11 has a slot 17 for tools, for instance screwdrivers or setscrew wrenches.
- the rotation of the first head 11 by means of a tool causes, in sequence, the rotation of the rod 15, the rotation of the tubular mean 40 and therefore, due to the threaded connection with the hole 12, the axial translation of the housing 10 by varying the compression of the elastic means 9 and, therefore, by varying the force applied to the first head 11.
- the first head 11 of each variant can have a longitudinal through hole 18 of small diameter fit to exhaust the pressure differences between the faces upstream and downstream the first head 11 in correspondence of an almost hydrostatics condition in order to avoid the stall of the valve means 6.
- the presence of the through hole 18 does not allow the total arrest of a flow caused by the shearing of the hose 2 but reduces said flow at extremely low and controlled levels.
- the variants of the device 1 shown in the figures 8 and 9, provide a cylindrical shaped container 20 to contain at least a part of the coiled hose 2.
- the container 20 has an opening 21 and at least a hole 22 for the liquid supply duct.
- the container 20 of figure 8 has a jointed connection 23 for the wall fixing designed to allow the container orientation in the directions of the outlet and the inlet of the coiled hose 2 and has a wide invitation of the opening 21 fit to facilitate the entry and the exit of the hose 2 avoiding the jam of the coils against the opening.
- the container 20 of figure 9 is underground-type, and is fit to contain completely at least the hose 2 and the dispenser 5 and has a cover to be trampled closing the opening 21 ; the hose 2 is connected to a underground waterworks 41.
- the coils of this latter at first are arranged in a conical shape then are stretched designing a curved line, for instance as shown in the figures 11B and 12B.
- the ends of the hose 2 have a first fitting 3 and a second fitting 4 fixed to the hose 2 by means of unthreading elements.
- the fittings, first 3 and second 4 have threaded portions respectively female, for instance for a source of liquid or pressure gas, and male for instance for a liquid dispenser or for a pneumatic tool.
- the device variant shown in the figures 11 A and 1 IB differs from the variant of figure 10 because the coils of the hose 2, in correspondence of a retract condition (in absence of solicitations), are plain and arranged on two parallel and adjacent surfaces in such a way that the ends of the hose 2 are in correspondence of the coils of bigger diameter and the two groups of coils are joined in proximity of their center.
- the coils of this latter are approximately shaped as a couple of cones joined at their vertex, as schematically shown in figure 1 IB.
- the coils of the hose 2 in correspondence of a retract condition (in absence of solicitations), are plain and arranged on two parallel and adjacent surfaces in such a way that the ends of the hose 2 are in correspondence of the coils center and the two groups of coils are joined in correspondence of the coils of bigger diameter.
- the coils of this latter are approximately shaped as a couple of cones joined at their bases, as schematically shown in the figure 12B.
- the plain coils of the hose 2 of the device according to the preceding variants can have more than two parallel plans.
- the main advantage of the present invention is to provide an extensible device to deliver a fluid, extremely easy and comfortable to use, having small dimensions and weight and therefore ergonomic; a device that do not cause the interruptions of the liquid flow because of foldings, narro wings and twistings or similar.
- a further advantage is to provide a device withstanding for indefinite time pressures up to over 10 bar and therefore also allowing the flow interruption by closing the delivery end of the device even during the non-operating periods and also preventing uncontrolled losses of liquid in case of cut or bursts of the same device.
- Further advantage is to provide a device which can be retract in coils into a container and which has small dimensions when is not extended; a device having a pleasant aesthetical aspect and a fast assemblage, a safe and hygienic operation and a long duration.
