Equipment and method for enhancing rowing motion

The present invention relates to a rowing motion facilitating method according to claim 1 and to a rowing motion facilitating device according to claim 2. The apparatus is preferably an oar with an actuator.

10 Various mechanical solutions are known in the art for reinforcing the force generated during a rowing movement in an oar. These have a number of drawbacks, including, for example, they do not produce a constant force on the oar or the desired force at each rowing movement.

The rowing motion enhancement apparatus according to the invention is an oar equipped with an actuator, preferably an electric motor or a hydraulic actuator, which functions in the same way as a power steering vehicle. The rower uses a powered oar just like a traditional oar, except that the powered oar provides extra power for rowing and felting.

20

Further, when rowing with an actuator, the force exerted by the rower is measured from the oar so that the greater the force exerted by the rower, the greater the auxiliary power of the actuator increases.

In the following, the invention will be explained in detail with reference to Fig. 1, which schematically illustrates an oar with an actuator, in this case an electric motor.

The rower holds his hand on the handle 2 of the oar 1, which has an indicator measuring the rowing force 30. During the soaking, the detector in the handle measures the instantaneous rowing power which it transmits for information to the actuator, preferably to the motor controller 3. The motor controller 3 further controls the motor 4. For example, a conventional brushed or brushing DC 111152 motor is suitable. The rotational motion of the motor is transmitted through the gearbox 5 to the oar 1 and produces a force which strengthens the movement parallel to the rowing motion. The motor and its controller are powered by a power supply 6, which is preferably operated by a battery or the like.

5

The principle of operating an oar with an actuator was described above. Alternative implementations include integrating the actuator-mounted oar mechatronics with either the oar or the boat. Another option is to use mechatronics that is detached from the boat or oar.

10 It can then be attached to a boat or oar.

The invention may vary within the scope of the following claims.

Claims (2)

3, 111152 1. Methods for förstärkning av roddrörelsen, kännetecknad därav, att i methodsen a wet roddarens roddkraft och enligt mätningsdatan styrs actuatorn som förstärker roddrörelsen och vidare förorsakas i aran momenten som förstärker 20 rörelsen. A method for amplifying a rowing motion, characterized in that the method measures the rowing power of the rower and, based on the measurement data, controls an actuator for reinforcing 5 rowing motion and further provides a moment for reinforcing the rowing motion. Apparatus for amplifying rowing motion, characterized in that the apparatus comprises a sensor for measuring rowing force located in the paddle portion of the paddle (part of the paddle towards the rower 10), from which measurement data is further directed to the paddle control motor and auxiliary torque motor. 15 Patent Claims 2.
