Description

Rowing or paddle sports training propeller

TECHNIQUE SECTOR

This application refers to a propeller for carrying out overspeed training in water sports where the athlete himself is the one who propels the boat such as canoeing (canoe/kayak), rowing, paddle-surfing.

STATE OF THE ART

Water sports such as canoeing (canoe/kayak), rowing, paddle surfing... demand, like other cyclical sports (athletic speed races, cycling.), a type of training known as overspeed .

This type of training seeks to produce adaptations in the neuromuscular system to improve force production at high speeds. On the other hand, due to the principle of training specificity, the training conditions should be as similar as possible to those of the competition.

For all these reasons, it is an objective sought over many years in these sports to find a way to externally propel the boats to work at competition speeds (without being constantly in peak form) or even, at speeds higher than those of the competition.

Although there have been alternative methods to the one presented here to do it, such as paddling/paddling behind a motorboat, paddling in team boats, use of air turbines, they have not been satisfactory since:

- They produce imbalances to the athlete (paleo after motor)

- They do not reproduce the specific movements of paddling / rowing (team boats)

- on very rough and little e cen ur nas e are

All of this has prompted the development of the present propellant of which the applicant is not aware of any device similar to the invention.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a training propeller for rowing or shovel sports. Its different variants solve the problems outlined.

The invention provides a hydrodynamic design that houses an electric motor that does not interfere with the athlete's training technique. It is fixed in the upper part of the boat, out of contact with the water, so that it does not produce friction losses. In addition, its size and mass is very small.

In short, what it is about is a kind of outboard electric motor for boats that is easy to install, light in weight and, once disassembled, does not affect the conditions of the boat.

The training propeller for this type of sports, applicable to boats, comprises a fixture, configured to be placed on an accessible surface of the boat. That is, a surface that is not found in the water under normal conditions of use. It will generally be a horizontal surface. A support is detachably connected to this fixing, which is finished off with a handle for a hydrodynamic submersible leg at the end of which an electric motor with a propulsion propeller is located. The leg will be vertical or with a small inclination with respect to the vertical.

In a preferred embodiment, the leg is longitudinally movable and lockable in the handle.

In the most preferred embodiment, the fixing comprises a triangular base configured to be fixed to the boat, and a rectangular plate with gray hair from here to years. Support has a space that corresponds to the shape and dimensions of the fixing so that they can be coupled without vibration. By having a certain "point" for the vertex of the triangular base and for the chamfers, it is possible to center both elements well and the final position is very stable. The removable connection can be, for example, by means of a support screw that can be inserted into a threaded hole in the fixing.

In order to reduce the aerodynamic and hydrodynamic effect, the fixation and the support are elongated and their respective longitudinal axes are coplanar with the longitudinal axis of the leg. That is, the extensions of the longitudinal axes of the fixation and the support are parallel and intersect with the longitudinal axis of the leg.

Other variants are appreciated in the rest of the report.

MODES OF CARRYING OUT THE INVENTION

An embodiment of the invention is briefly described below, as an illustrative and non-limiting example thereof.

Proposer mosra or in area zac n e agura compren e un ac n (1) configured to be placed on an accessible surface of the boat. This fixing (1) will remain fixed to the boat at all times, and for this reason it is small in size and weight. It can be fixed, for example, with a high-strength adhesive.

The next element is a mobile support (2), detachable from the fastening (1), and which is finished off with a handle (3) for a submersible leg (4) whose end includes an electric motor (5). The motor (5) is connected to propellers (not shown). Both the motor (5) and the propellers are commercially available, so they do not require further explanation. The power of the engine will depend on the size of the boat and the skills of the athlete, as well as the type of propeller (size and number of blades) provided. It will generally be of the "brushless" type. A watertight box (6) will contain the battery and the electronics. The box (6) can be fixed by conical supports and screws, all waterproof, at a certain distance from the fixing (1). In this case, a cable will be connected to a socket (41) at the end of the leg (4) to carry electricity to the motor (5).

An ignition and power regulation control will be connected to the engine (5), for example, through the leg (4) and will remain accessible to the crew. The system can be wireless, with a receiver at the top of the leg (4) connected to the motor. Power to the motor (5) will be from the battery. Commands can be sent from a remote control (not pictured) or from a panel on the front of the rower. Both can be sent wirelessly or wired.

The leg (4) is generally vertical and has a hydrodynamic profile to affect the behavior of the boat as little as possible. The leg (4) is movable longitudinally on the handle (3) to regulate the depth at which the motor (5) is inserted depending on the boat model. A tightening screw, pin or other system locks the leg (4) in the desired position.

acn is shown in ea e in a gure. They comprise a triangular handle (11) topped with a plate (12). The plate (12) is approximately rectangular, but with chamfered edges to facilitate the introduction of the fixing (1) in the support (2). The support (2) will be inserted from an edge of the triangular base (11), coinciding with the chamfered edges of the plate (12).

The fixing (1) and the support (2) are elongated (width much less than the length) and their respective longitudinal axes are coplanar with the longitudinal axis of the leg (4). It can be seen in figure 1 that it allows the propeller assembly to be essentially flat, and does not include a type of lateral protrusion. For example, no type of rudder is required since the crew members will steer with their oars.

The support (2) has a space (21) corresponding to the shape and dimensions of the fastening (1), and a screw (22) that must be able to be inserted into a threaded hole (13) of the fastening.

Given the use of the propellant, all electrical and electronic equipment will be protected from moisture and the ingress of water.
