DETAILLED DESCRIPTION OF THE INVENTION

[027] As iUustrated in Figures 1 to 14, there is provfrJed a device iF for enahhng multiple use of a water stream from a personal water craft (PWC) 50, such as an water exhaust. The objective of the device 10 is to enable a user to selectively use the pressurized water provided by the water stream for operating the PWC only 10, the personal propulsion device (or any other water operated external device) only (not shown) or both of these devices simultaneously.

[028] The device comprises a hub 12, at least one valve 14, a control unit 16 having a user interface 18, a first conduit 20, a second conduit 22, a floating jacket (not shown) and support members 24. The hub 12 is in fluid communicaUon with the water exhaust of the PWC 50, the bucket 30 of the PWC and the personal propulsion device (not shown) such as the one rJescribed in IJS patent 7. 258. 301. Though, a person skilled in the art would appreciate that the device 10 can operate with any water operable device (and not necessary a personal propulsion device).

[029] The hub 12 is substantially in the form of a hollow body having a longitudinal axis extending along a first extremity to a second extremity of the hub 12. The body is preferably made of a solid plastic material, such as P\IC. The huh 12 has an inlet port 32, two outlet ports 34 and 36 and a wall 38. The wall has a bottom: portion, an upper portion and side portions. The inlet port 32 s essentially an opening at a first extremity of the hub 12 and extending in height from the inlet port bottom edge at the bottom portion of the wail 38 to the inlet port upper edge at the upper portion of the wall 38, and in width along its side edges at the side portions of the wall 38. The first outlet port 34 is essentially an opening at a second extremity of the hub 12 opposite the first extremity and extending in height from the first outlet port bottom edge at the bottom portion of the wall 38 to the first outlet port upper edge at the upper portion of the wall 38 and in width along its side edges at the side portions of the wall 38. The height of the inlet port 32 is smaller than the height of the first outlet port 34. The upper portion of the wall 38 extends substantially parallel to the longitudinal axis from the inlet port 32 upper edge to the first outlet port upper edge. The bottom portion of the wall 38 is inclined and projects downwardly at a given angle from the inlet port bottom edge to the first outlet port bottom edge.

[030] The inlet port 32 of the hub 12 is in fluid communication with the water exhaust of the PWC 50. The inlet port 32 is therefore configured to be coupled to the water exhaust of the PWC 50. The type of configuration depends on the type of the PWC 50. For example, fixing members 40 can extend from the edges of the inlet port 32 and be configured to be coupled to the water exhaust of the PWC 50. The inlet port 32 can be coupled directly to the water exhaust of the PWC 50 or through an intermediate tube (not shown). However the first option is preferred to avoid water leakage and/or decrease in the water pressure.

(0313 The first outlet port 34 of the hub 12 is in fluid communication with the personal propulsion device (not shown). The first outlet port 34 is configured to be removably coupled to a first conduit 20 for directing the first flow of water towards the personal propulsion device. The first conduit 20 is therefore configured to be removably coupled to the first outlet port 34 at one end and to the personal propulsion device at a second end. The first conduit 20 is also configured to extend substantially symmetrically along both sides of the PWC 50 between the stern and the bow of the PWC 50. The first conduit 20 is therefore divided in two branches close to the outlet port at the stem of the PWC 50 where the first branch extends along a first side of the PWC 50 and the second branch extends along a second side of the PWC 50 substantially symmetrically to the first branch, and both branches join again in proximity of the bow of the PWC 50. The first conduit 20 has a first ring having a first end configured to be coupled to the first outlet port 34 and a second end through which the two branches diverge. The second ring is configured to receive the two branches from one end and to be coupled at a second end (directly or through the intermediate of an independent hose) to the personal propulsion device. Though, other configurations can be provided.

(032] This configuration of the first conduit 20 permits the first flow of water to be dMded Into two separate flows of water, each one being directed through one of the branches in such a manner that the mass of the water is shared substantially equally between the two branches at each side of the PWC 50 between the bow and the stem. This permits securing a weight balance at both extremities of the PWC to avoid over flipping of the latter when the personal propulsion device is In operation.

(0333 The first conduit 20 can be a fire hose type of conduit or any other type of suitable configuration and dimensions for carrying a water flow of a sufficient mass and pressure to operate the personal propulsion device, preferably of a flexible material. The first conduit 20 is preferably configured to float over the water when it is either empty or full of water. It can for example be enrobed with a floating material, such as foam or polyester, at its outer edge. There can also be provided a jacket made of a floating material, such as foam or polyester, independent of the first it conduit to receive the latter and permit it to float over the water.

(034] There is also provided support members 24 for supporting the first conduit 20 and the jacket to the PWC 50. The support members 24 have a first part configured to be fixed to the PWC and a second part configured to receive the first conduit and the jacket. The first part can have the form of leg extensions of an adjustable length configured to be fixed (for example bolted) to the PWC and to adjustably extend outwardly at a desired distance. The second part can have the form of a removable collar or ring of adjustable dimensions configured to be removably coupled to the extension legs for supporting the first conduit 20 and the jacket.

(035] The second outlet port 36 of the hub 12 is in fluid communication with the bucket 30 of the PWC 50. The second outlet port 36 is configured to be removably coupled to a bended tube 22 in fluid communication with the bucket 30 of the PWC 50. The bended tube 22 has a shape of a half circle (or a C) having a downwardly Inclined portion, a bottom portion and an upwardly inclined portion and is configured to be removably coupled to the second outlet port 36 at Its downwardly inclined portion end and to the PWC bucket 30 at its upwardly inclined portion end. The bended tube is preferably made of a solid plastic material, such as PVC. The second flow of water is directed downwardly through the second outlet port inside the downwardly inclined portion of the bended tube 22 and then oriented towards the bucket of the PWC through the bottom portion and upwardly inclined portion of the bended tube 22. The bottom portion of the bended tube would be under the water during operation.

(0361 The bucket 30 is configured to permit the first flow of water to be directed rearwardly in a forward driving position of the PWC and to direct the first flow of water in a forward direction In a reverse driving position of the PWC 50. For purpose of clarity, the term 0operation" or "operating the PWC" referred to in this description is referred to putting the PWC 50 in a driving position (forward or reverse driving position).

(0371 In an alternative embodiment, the bonded tube 22 can be configured to receive a reversed tube extension between its downwardly and upwardly inclined portion ends to outlet the first flow of water In a forward direction for a reverse driving position of the PWC 50. A valve can be located at the junction between the reversed tube extension and the main bended tube 22 to selectively direct the first flow of water according to a selection made by the operator on whether to operate the PWC in a forward or reverse driving position. If the selection is for a forward driving position, the valve will direct the first flow of water towards the end of the bendS tube (the upwardly inclined portion end). If the selection to operate the PWC 50 in a reverse position, the valve will direct the first flow of water inside the reversed tube extension. A reverse bucket will not be necessary in this case.

(0381 When the inlet port 32 of the hub 12 is coupled to the exhaust tube of the PWC, the pressurized water stream from the PWC is propelled in a first direction along the longitudinal axis from the inlet port towards the first outlet port. A first flow of water can therefore be directed inside the first outlet port 34. A second flow of water can also be directed along a second direction inside the second outlet port 36 when this is submerged with water. The second outlet port 36 being positioned at the inclined bottom portion of the wall 38, the second direction projects substantially downwardly opposite the first direction. This configuration permits biasing the higher pressure of water towards the first outlet port 34 when both the first and second outlet ports are opened, permithng therefore the operation of the personal propulsion device with a higher water power than the PWC. The latter can still operate simultaneously with the personal propulsion device at a decreased power.

(039) The device also comprises at least one valve 14 configured to be connected to a control unit 16 for controlling the first and second flows of water. The valves 14 can be positioned at different locations. In a first configuration, a first valve is positioned between the first outlet port 34 and the first conduit 20 first end for controlling the first flow of water, and a second valve Is positioned between the second outlet port 36 and the second conduit 22 first end for controlling the second flow of water. Alternatively, the second valve can be positioned at the second conduit (bended tube) 22 at the bottom portion between the downwardly inclined portion and the upwardly Inclined portion of the bended tube 22. Also1 the first valve can be replaced by two valves positioned respectIvely at each branch of the first conduit at each side of the PWC. These should preferably be positioned symmetrical with respect to each other and to the longitudinal median axis of the PWC to sustain a balance in the water mass inside the two branches of the conduit.

AlternatIvely to these configurations, a three port valve can be positioned inside the hub 12 for controlling the first and second flows of water.

(040] A control unit 16 is provided and configured to be connected to the valves and to the electrical power source of the PWC through waterproof electrical wiring. The control unit 16 is configured to enable a user to select an option among operating the PWC only, operating the second device only, or operating both the PWC and the second device at the same time. The control unit sends electrical signals to the valves 14 for controlling the first and second flows of water based on the user's selection.

(041] The control unit 16 orders the valves to close the second flow of water and open the first flow of water when the selected option is to operate the personal propulsion device only, to close the first flow of water and open the second flow of water when the selected option is to operate the PWC only, and to open both the first and second flows of water when the selected option is to operate both the PWC and the personal propulsion device simultaneously.

(042] The control unit 16 is also configured to enable a user to variably regulate the first and second flows of water and therefore to variably control the distribution of water power between the personal propulsion device and the PWG when both are to operate simultaneously. The control unit can therefore control the degree of opening and closure of the valves 14 (partial opening and closure) as a function of the desired distribution of power between the devices.

(043] The control unit 16 comprises a user interlace 18 enabling a user to select different options for controlling the PWC and the personal propulsion device. The user interlace can for example comprise electrical switches where each switch has a suitable electrical configuration and connection to the valves.

[044] The method of operating the device is as follow: coupling the hub 12 to the water exhaust of the PWC 50; coupling the first conduit 20 to the first outlet port 34 and to the personal propulsion device; coupling the second conduit 22 to the second outlet port 36 and to the bucket 30 of the PWC; turning on the engine of the PWC and regulating the power of the PWC for enabling the pump of the PWC to generate a desired water stream intensity; using the first water flow directed through the first outlet port 34 to operate the external device; using the second flow of water directed through the second outlet port 36 to operate the PWC; and controlling the first and second flows of water for selectively operating the PWC only, the external device only, or both the PWC and the external device simultaneously. The intensity of the water stream and therefore the intensity of the first and second flows of water can be regulated by regulating the power of the PWC engine.

(045] While the present Invention has been described in details and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various additions, omissions and modifications can be made without departing from the spirit and scope thereof.
