Description

WATER BIKE

D E S C R I P C I O N

SECTOR OF THE TECHNIQUE

The present invention relates to an aquatic bicycle, whose evident purpose is to provide a device that allows to move on an aquatic medium.

The object of the invention is to provide a water bicycle with a lightweight and compact structure, extremely stable, safe and with high buoyancy, structure that allows a self-upright of the device before a fall or the like, both longitudinally and transversally.

BACKGROUND OF THE INVENTION

Numerous recreational devices of similar configuration to that of a bicycle are known, whose structure has been duly adapted to make possible its displacement on water.

In this sense, utility model U201800001 can be cited, in which a water bicycle with a pedaling system assisted by an electric motor is described, comprising two helmets joined by a frame, sitting on a platform, and in which the The vehicle is propelled by manual pedaling with connection to an electric motor, so that the frame where the frame or main body of the bicycle is seated has the pedals associated with a transmission that operates a propeller on the bottom, so that said transmission is assisted by an electric motor.

Although this type of devices fulfill the function for which they have been foreseen, the helmets that participate in it offer a large friction surface between them and the water, which drastically limits the speeds at which the device can move.

Trying to obviate this problem, aquatic bikes are known that in replacement of the classic floats or helmets include a pair of transverse hydro-wings or "hydrofoils" , which emerge from a vertical arm, adopting an inverted "T" configuration on the frame or main frame of the vehicle.

Although the use of this type of technology drastically reduces friction with water and consequently reaches higher speeds, the inverted "T" configuration of these hydro-wings means that these vehicles must be handled with great skill, given that the The stability that they offer is precarious, being very insecure and presenting a low buoyancy when the bicycle does not move at a minimum speed from which the hydro-wings begin to be effective.

Moreover, this type of devices before a fall do not tend to adopt an upright position, which complicates the maneuvers when re-mounted on the device.

EXPLANATION OF THE INVENTION

The aquatic bicycle that is recommended solves in a fully satisfactory way the problems previously exposed, based on a simple but effective solution that gives it greater buoyancy, stability, safety and self-righting.

For this, and more specifically, the bicycle of the invention is constituted from a main frame or frame, in which the main elements will be established in this type of devices, such as a seat, handlebar, and a mechanism of pedaling, which could be optionally assisted by an electric motor, with its corresponding rechargeable battery.

Well, according to the essence of the invention, it has been foreseen that from the front and rear of the frame emerge respective hydro-wings, which extend obliquely from both sides of the frame in a downward direction, to be finished inferiorly in a section horizontal and common, so that each of the two hydrofoils participating in the bicycle adopt a closed and symmetrical trajectory with respect to a plane imaginary of vertical and longitudinal symmetry to the frame, in which a Inner water flow to the hydro-wings that causes greater stability of the device.

The pedaling mechanism will be associated with an electric power system for a jet or waterjet turbine that will be established in the middle zone of the horizontal section of the rear hydrofoil.

The use of turbines instead of propellers allows the device to be used from the shore, with a minimum draft, without risk of damaging the propulsion mechanism. Also, as such the propeller by jet or "waterjet", with its main rotating element encapsulated in its nozzle, prevents possible damage to both the person who handles the bicycle, and other bathers who may be reached accidentally, thus preventing it from being caused sharp wounds of consideration.

The bike thus described could incorporate in its frame, in its antero-superior zone a display or interface in which to visualize different data of interest, such as speed, distance traveled, autonomy of the battery, etc.

The special structuring and configuration of the bicycle, together with the buoyancy of the hydro-wings, makes the bicycle tend to self-up when it is submerged in the water, both longitudinally and transversally, which considerably facilitates the lifting maneuvers and start-up, even in the event of a fall.

It only remains to note finally that the hydro-wings could be articulated with respect to the main frame of the bicycle, including blocking means, in order to confer on the assembly a folding and / or rapid disarticulated character of the assembly that causes the device to present a minimum volumetric occupation in inoperative situation, facilitating transport and storage.

From this structuring, the following advantages are derived:

• Any voluminous element, or static flotation tire, is dispensed with.

• Presents a structure with greater benefits from the point of view of safety, buoyancy and stability.

• Offers the ability to start from the resting position, without the need for an initial impulse from a dock or jetty.

• It allows to start the movement, both from a position afloat, as from the shore of the beach, lake, river, marsh, etc.

• The bicycle tends to self-curl both longitudinally and transversally when it is afloat in the water, due to its special structuring of sealed volumes and its exprofeso distribution of weights.

• It has an articulated character, which facilitates its transport and assembly.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures, it can be observed how the aquatic bicycle of the invention is constituted from a main frame (1) or frame, in which the main elements will be established in this type of devices, such as a seat ( 2), handlebar (3), and a pedaling mechanism (4), where the pedaling mechanism will be optionally associated with an electric motor, with its corresponding rechargeable battery to facilitate the user's pedaling.

From the front and rear of the frame emerge respective hydro-wings (5) and (6), which extend obliquely from both sides of the frame (1) in a downward direction, to be finished inferiorly in a horizontal and common section (7) and (8), so that each of the two hydro-wings participating in the bicycle adopt a closed and symmetrical trajectory with respect to a plane imaginary of vertical and longitudinal symmetry to the frame (1).

The pedaling mechanism (4) feeds a jet propulsion turbine (9) that will be established in the middle zone of the horizontal section (8) of the rear hydrofoil (6).

In its antero-superior zone (10) it is possible to incorporate a display or interface in which to visualize different data of interest.

As shown in figures 6 and 7, the special structuring and configuration of the bicycle, makes it self-correct when it is submerged in water, both longitudinally and transversally. The most important weights of the set are the turbine (9) and the pedaling mechanism (4), so that the resulting vector of weights P of the bicycle will have its point of application in the line that joins both elements. The zone of greater buoyancy or push E will be established in the anterior middle area of the frame (1).

In this way, the vector of the weight P is aligned at the moment of staying afloat with the point of application of the push vector E, which will approach the anterior middle area of the frame which has a widened configuration.

As seen in figures 6 and 7 in correspondence with the area of maximum buoyancy or thrust E and weight P a pair of self-upright of the bicycle is established when it is submerged.

From this structuring, two modes of start of the march are foreseen, either from the shore, or from a position afloat.

When it comes to starting the march from a afloat position, as has been said before, the water bicycle stays afloat on its own by means of its balanced distribution of watertight volumes, as shown in figure 7. This allows easy access, grip to the handlebar and reposition on the bicycle as shown in figure 8, so that this immediately by the own weight of the cyclist acquires the relevant inclination so that the thrust of the turbine is adequate to guide the flow of water towards the hydro-wings, in the optimal direction and angle of attack, to achieve the greatest vertical lift thrust.

It is then, when when starting the pedaling, the turbine drives the set, acquiring speed of advance and emerging due to the lift effect generated by the hydro-wings.

Finally, once the maximum emersion process has been carried out, the bicycle is supported above the surface, as long as the necessary pedaling is maintained so that the propulsion turbine provides the assembly with the minimum lift speed.

At the same time, and as has been said before, the use of a jet propulsion turbine, unlike a conventional propeller, allows us, among other advantages, to start walking, while the bicycle remains stably on the shore, thus favoring easy access, in addition to avoiding injuries to both the person who handles the bicycle, and other people who may be accidentally wound up.

In this way, by simply starting the pedaling, the turbine propels the system and the hydro-wings provide the lift, to raise the assembly again, on the surface.
