The invention relates to a water jet device for recreational purposes, for example of the fountain type or the like.
Known from the prior art are such devices with cascading water jets forming in particular a curtain of water. Such a device usually comprises several water outlets distributed along one direction, for example along a tube which may be rectilinear, so that the set of jets forms said curtain of water.
A form of water jet device can give pleasure to users, not only visual or auditory (from the sound of falling water), but also to cool off, with it being possible for users to position themselves as illustrated in
However, in the usual devices of this type, the jets JET (reference in
The invention improves the situation.
It proposes a water jet kit for recreational purposes, comprising:
Thus, in such an embodiment, said retaining beams are replaced by a (hollow) column which conveys the water from a collection tank to an outlet tank by means of the cooperation of the pump with this column. This column is advantageously made of a material that is rigid in order to support the outlet tank, and translucent in order to blend with the curtain of water generated by the flow of water from the outlet tank. The column thus has the following functions:
supporting the outlet tank,
conveying water to this tank,
while being inconspicuous to an observer.
The invention relates in particular to a kit which combines an outlet tank and a collection tank with at least one water column. As will be seen below, it is then possible to fit together several successive outlet tanks and in a homologous manner several collection tanks, therefore in association with several respective translucent rigid columns, with a sufficient number of columns to support the number of water outlet tanks once fitted together.
Each supply column may be fixed (for example fitted together, for example snap-fitted or “clipped” hereinafter) at its lower end to the collection tank and at its upper end to the water outlet tank. The pump, which allows the water collected in the water collection tank to be conveyed to the outlet tank through the column, is directly connected to the supply column. The outlet tanks are able to be fitted together (by clipping into place or other means), for example by a connection between a tubing protuberance and a cavity respectively positioned on two outlet tanks (as illustrated at the top of
As illustrated at the bottom of
Alternatively, a threading may be provided in the openings 7, for screwing the column ends therein.
In the embodiment shown by way of example in
For example, when the collection tanks are rectangular and straight as shown in
Furthermore, the collection tanks are, at least in an upper portion, of a deformable rigid material making it possible to clip them to each other. However, a more flexible material may be used for the lower portion of the collection tank (the underside of the reservoir 12 as illustrated in
For example, this flexible material can be chosen so that it floats on water, to allow its use in a swimming pool for example, enabling the kit to float on water and use the water from the pool as its water supply.
Regarding the water outlet tank, this tank may comprise a plurality of water outlet nozzles positioned on the lower surface of the water outlet tank and in a same plane. The nozzles may be equidistant from each other and distributed over the entire surface in order to obtain a curtain of water, or distributed over only part of the lower surface of the tank, for example to allow a user to pass underneath the tank without being sprayed.
The nozzles may be holes drilled in the thickness of the material of the water outlet tank to allow water to flow continuously to the outlet tank, or in another embodiment for example, the water outlet tank may be fitted with connected nozzles making it possible to obtain different forms of jets (typically in jets forming segments, dashes, or drops).
The outlet tank and the collection tank are of homologous shapes (straight rectangular but alternatively may be polygonal, angular, straight or curved).
Furthermore, as illustrated in
Thus, in one embodiment of the invention, the kit comprises at least first and second outlet tanks, the first outlet tank comprising a cavity on a first side face, and the second outlet tank comprising, on a first side face, a tubing protuberance suitable for being housed in the cavity of the first outlet tank.
In one embodiment of the invention, the kit may further comprise at least a third outlet tank, intermediate between the first and the second outlet tank, comprising:
In one embodiment of the invention, the first side face is opposite to the second side face.
Such an embodiment may require several water supply columns in order to maintain the water outlet tanks at their height, the outlet tanks thus being stable in order to obtain a flow without disruptions.
The tubing of a first tank can be housed in the cavity of a second outlet tank of the same or different shape, making it possible to create kits of original shapes such as heart-shaped for example (in a manner similar to the shapes of the water collection tanks illustrated in
In one embodiment of the invention, the third outlet tank comprises, in addition to the first and second side faces, at least a third side face comprising one element among:
A cavity is mounted on a first face of the outlet tank, this first face being opposite to a second face where for example a tubing protuberance is mounted. This arrangement allows “end-to-end” assembly between a plurality of water outlet tanks, the cavity of one outlet tank receiving the protuberance of another outlet tank.
In one embodiment, a third side face of an outlet tank may comprise a protuberance or a cavity and allow connecting a fourth outlet tank. The third outlet tank can then be triangular in shape, for example, making it possible to create intersecting water curtains when water flows through the various water outlet tanks.
The outlet tanks may be x-shaped, angular, or have a general “V” shape, to implement the preferred shapes.
In one embodiment of the invention, one among the first and second water outlet tanks comprises, on a second side face opposite to the first side face, a partition for closing off the outlet tank.
For example, a rectangular outlet tank may be arranged at only one of these side faces to receive a second outlet tank at one of these ends and to close off the assembly line of tanks at a second end opposite to the first. “Close off” is understood to mean stopping the flow of water within the tanks.
Special shapes for these outlet tanks can be provided, such as a pointed shape or a horn shape for example.
The outlet tanks are preferably rigid to allow containing the water higher up, before it flows through the nozzles.
The tanks (outlet or collection) may have a straight parallelepiped shape (in the shape of a rectangle when viewed from above, as illustrated in
It will thus be understood that the assembly of tanks two by two generates a continuous line as illustrated in
Alternatively, a singularity may be provided in the line created by the assembly of tanks (such as the heart illustrated in
The tubing protuberance of the outlet tank and of the collection tank may be hollow, in order to allow the water injected by the supply column to be distributed among the various assembled tanks. Alternatively, the non-functional pipes can be plugged with a stopper (for example of rubber) in the event that no second tank is assembled to this face of the collection tank.
For sealing concerns between the various tanks (here we mean between two water collection tanks or two water outlet tanks) a flexible gasket (typically rubber) can be provided and placed between the two tanks.
The water supply column, made of a rigid and translucent or transparent material to support the water outlet tank (typically a polymer for example of plexiglass, glass, or other), here is straight and of the same shape as the jets in order to blend with the jets coming from the outlet tank. The column can be placed for example at the center of the tanks or alternatively at least two columns can be provided at the respective sides of the water collection tank.
The column may comprise several column elements, fitting together (by threading or by clipping), in order to increase the height of the water outlet tank relative to the water collection tank.
Alternatively, a threading system may be provided for assembling two column elements or one column element to one of the tanks, the column comprising an internal thread at a first end and an external thread at a second end. The external thread of a first column element is able to screw into the internal thread of a second column element.
The pump is connected to the column in order to suck water from the collection tank and inject it into the supply column. The injected water enters the water outlet tank and flows through the nozzles, for example in straight jets directed towards the water collection tanks. The pump may be directly positioned in the reservoir 12, making it possible to render it invisible to the user's eyes. This embodiment optionally allows water to circulate in a closed cycle. The reservoir of the collection tank can be pre-filled with water by the user, the water being in constant circulation without an external supply. The pump itself can be powered electrically by a connection to the grid or alternatively by photovoltaic modules, particularly in an application in an outside environment.
Alternatively, an external water supply to the tanks may be provided (for example in an outdoor environment such as a garden, where the user can use a garden hose) and connected to the water collection tank at one of the openings. This circulation, with an external water supply, allows a continuous water supply when external elements such as wind can disrupt the direction of the water jets and create water loss.
The water collection tanks may further have a curved shape with the curvature as shown in
Thus, in such an embodiment, said third intermediate collection tank, at least, is shaped to be higher relative to at least one among the first and second tanks (which are on the sides) in order to generate a passage with no water flowing under this third tank. Such an embodiment is advantageous for devices of the ornamental fountain type, but also for carrying out, for example, maintenance work on pre-existing fountains (city or other), this passage then allowing workers to test the water jets and to move under them without being sprayed. Thus, in such a case, the third intermediate tank (or successive intermediate tanks) can be shaped to create this passage, and for example can be curved along its length for this purpose, as illustrated in
The water outlet tanks may alternatively be equipped, for example, with presence sensors making it possible to cut off the flow of water when the user stands in front of the curtain of water.
It should be noted that a collection tank may comprise, as illustrated in
The protuberance and the cavity being positioned at the level of the reservoirs of the collection tanks (here meaning the lower portion of the water collection tanks), allowing the flow of water between the various tanks connected by this third side face, the protuberance being hollow.
Such an embodiment typically makes it possible to enlarge the water collection surface (especially outdoors in windy conditions).
In one embodiment of the invention, at least one among the first and second water collection tanks comprises, on a second side face opposite to the first side face, a partition for closing off the water collection tank.
In one embodiment of the invention, the supply column is created from a plurality of segments comprising:
The various column elements fit into each other in order to increase the height of the water outlet tank relative to the water collection tank, and therefore to adapt to the environment where the kit is installed.
In one embodiment of the invention, the supply column comprises at least a third segment, intermediate between the first and second segment, comprising:
In one embodiment of the invention, the kit further comprises:
The pressure gauge may be placed in the water outlet tank or at the outlet of the supply column, making it possible to measure the pressure of the water arriving from the supply column or in the outlet tank. If the pressure in the water outlet tank, measured by the pressure gauge, is lower than a defined threshold (this threshold can be defined so as to obtain a continuous flow of water for example), the flow regulator increases the flow of water by controlling the water supply connected to the water collection tank so as to return to the minimum threshold.
In one embodiment of the invention, the flow regulator is configured to cut off the supply of water to the nozzles cyclically, and to cause a cyclically interrupted jet to exit each nozzle.
In an alternative or complementary embodiment, the kit comprises, at each nozzle outlet of the outlet tank, at least one outwardly opening valve, hinged and urged inward by a spring.
The water outlet comprises a multitude of nozzles allowing water to flow through. The nozzles are composed of several valves connected by a hinge to the outlet tank on the external face of the valves and of the outlet tank. The nozzle valves are also attached to the tank by a spring placed on the underside of each valve and attached to the internal face of the tank. The water pressure in the outlet tank enables the valves to open during the flow of water (the nozzles being in the open position), the valves returning to their initial position (i.e. nozzle in the closed position) when the water pressure becomes insufficient, thus creating jets of water interrupted by cycles, forming segments or drops.
Thus, in this embodiment, the flow regulator is formed by said valves, in cooperation with the water infeed, and:
In one embodiment of the invention, the kit comprises an anemometer to identify the wind direction and force and then increase the water flow rate.
In a less sophisticated embodiment, the device may simply comprise at least one sensor for detecting the presence of wind and at least cyclically interrupting the water jet according to the force of the wind, into successive water segments or drops.
More generally, a sensor for detecting an air displacement (due to wind, or, for example, simply inside a room due to turning on a fan or other cause) may be provided, and if the force of the detected air displacement is greater than a threshold, the operation of the pump can be completely cut off to eliminate the risk, for example, of spraying users near or under the fountain.
Other features, details and advantages will be apparent from reading the detailed description below, and from analyzing the accompanying drawings, in which:
In particular, the column 3 comprises a lower end suitable for insertion by force into the opening 7 of the collection tank 1, preferably all the way to a tubing 40 of larger diameter 40 connected to the pump 4. For example, the opening 7 and the outlet tubing 40 of the pump 4 can be of a diameter greater than that of the column 3 or the column 3 may comprise an external recess to be fitted through the opening 7 all the way to the tubing 40. The pump 4 comprises another tubing leading to the bottom of the reservoir 12 in order to suck in water from the bottom of the reservoir and reinject it into the outlet tubing 40 receiving the column 3. In addition, an upper end of the column 3 can be inserted by force into an opening 8 of the water outlet tank in order to supply it with water. For example, this second upper end may comprise an external recess for insertion into the opening 8 of the outlet tank 2.
In the example of
The water outlet tank 2 comprises a plurality of nozzles 5 on its lower face, generating a curtain of water when the water flows through the nozzles 5, the column 3 blending in with this curtain (being transparent or translucent). The nozzles are distributed over the entire surface of the lower face of the outlet tank 2, equidistant from one another. In a variant, the nozzles may be distributed only along an edge of the tank 2, close to a side partition, or even on a side partition and not on the lower face so as to give a dome effect to the curtain of water falling from the outlet tank 2.
The water, falling from the outlet tank 2, reaches the trough 18 of the water collection tank 1, and here this trough 18 has at least one hole 6 in its lower face in order to collect the water from the trough into the underlying reservoir 12. Such an embodiment makes it possible to filter from the water any debris or dust which could land in the trough 18. Furthermore, the reservoir 12 contains the pump 4 placed at the inlet of the column 3, leaving the pump invisible to the user's eyes.
The kit is supplied with water by filling the reservoir 12 beforehand or by connecting an additional water infeed, for example via one of the openings 6 of the water collection tank 1 for example, using for example a garden hose when the kit is placed outdoors.
The upper face of the outlet tank 2 is closed off. The outlet tank 2 may further comprise at least one plug 11 making it possible to close off the tubing protuberances in the event that no assembly with another outlet tank is performed.
Referring now to
The column 3 may be composed of several column elements, as illustrated in
The first column element is inserted at a first end into the central collection tank 1 (in the center of the tank in the example shown here) and at a second end into a second column element. Several column elements can be assembled together and a last column element is inserted into an opening of the outlet tank 2. The assembly of column elements allows water to be conveyed from the opening 7 of the collection tank 1 to the opening 8 of the outlet tank.
In the embodiment where the water infeed is not activated (as illustrated in
Of course, the invention is not limited to the embodiments presented above by way of example, but extends to other variants.
For example, there can be multiple shapes created by assembling the kit.
The elements may be fitted together by different means other than those described above (cooperation between protuberance-cavity, internal-external recesses, threading, etc.)
