Definitions

  • a rowing machine with a frame and sliding seat is a well-known type and is commonly found, for example, in the US 4,396,188
  • the frame has two support legs that stand firmly on a base.
  • the braking device creates a certain resistance that must be overcome when pulling the oar handle.
  • the trainee rolls backward on the sliding seat, supporting themselves with their feet on a footrest that is firmly attached to the frame.
  • the trainee rolls toward the bow of an imaginary rowing boat.
  • a second phase follows in the rowing cycle, in which the trainee rolls back toward the stern of the imaginary rowing boat on the sliding seat and returns the oar handle to the starting position.
  • the next rowing cycle then begins with the two phases of pull and recovery. Due to the fixed frame with the footrest firmly mounted on it, the US 4,396,188 will be the focus of The trainee is moved back and forth in the main rowing direction during the rowing cycle and in the opposite direction.
  • a rowing machine in which the frame is not fixed, but rather mounted on a sliding mechanism that allows it to move along the main rowing direction.
  • the frame and the footplate which is fixed to it, move back and forth.
  • Two slightly tensioned elastic cords prevent the sliding mechanism from running undamped against end stops during rowing.
  • the sliding mechanism is designed to provide a more natural rowing feel. Essentially, the center of gravity of the user, or rather the center of gravity of the system consisting of the frame, braking device, and user, remains virtually unchanged in the same position throughout the rowing cycle.
  • the invention is therefore based on the objective of providing a rowing machine that replicates real rowing on water as closely as possible.
  • an actuating device is provided to supply an actuating force by which the movement of the footplate can be decelerated or accelerated to simulate the propulsive force and resistance of a (virtual) rowing boat on water.
  • the movement of the footplate is relative to a fixed, stationary surface that does not change during rowing on the rowing machine.
  • the user on the rowing machine supports themselves with their feet on the footplate. During free-running, they can pull the footplate towards themselves with their feet using optional foot or shoe straps.
  • the actuating force thus allows the movement of the footplate to be selectively decelerated and/or accelerated in the main rowing direction or in the opposite direction.
  • the footrest In a rowing boat, the footrest is firmly attached to the hull. Therefore, the speed of the footrest in a rowing boat is directly proportional to the boat's speed. The speed of the rowing boat is always the same at any given time. However, the speed of the rower, who sits in the rowing boat and rolls back and forth while rowing, differs significantly from the boat's speed.
  • the invention is based on the understanding that the speed of a rowing boat on the water depends—in addition to the shift in the center of gravity of the rower or crew (primarily caused by the forward and backward movement of the sliding seat)—on the boat's propulsive force and the boat's resistance force, and that while the boat's speed is not constant throughout the rowing cycle, the speed at the beginning of the cycle corresponds to the speed at the end.
  • the influence of the boat's propulsive force and the boat's resistance force on the boat's speed is replicated by the actuating force acting on the footplate of the rowing machine.
  • the propulsive force of a boat is the force that, during rowing, is transferred from the water to the hull and/or the rower through the oars or sculls.
  • the boat's resistance force is primarily due to the friction between the hull's outer surface and the water.
  • the boat's resistance force is proportional to the square of the boat's speed relative to the (still) water, or—viewed in the main rowing direction—to the square of the difference between the boat's speed and the water's speed.
  • the boat's propulsive force acts in the main direction of rudder movement and generally contributes to the boat's acceleration
  • the boat's resistance force acts against this direction and decelerates the boat.
  • These two forces are superimposed by the rower's shift in their center of gravity. or the rowing crew relative to the rowing boat.
  • a backward rolling motion of the rower towards the stern during the recovery phase leads to an acceleration of the rowing boat, which reduces or possibly exceeds the braking effect of friction against the boat's outer hull during the recovery phase.
  • the boat speed i.e., in the phase of the rowing cycle in which the system consisting of the rowing boat and rower is actively propelled, the boat speed generally increases.
  • the force curve has a first zero point, a second zero point, and a maximum located between these zero points.
  • the force increases monotonically from the first zero point to the maximum and then decreases monotonically to the second zero point.
  • the maximum force can be between 100 and 500 N, preferably between 150 and 250 N.
  • the actuating force is consistently less than zero.
  • the actuating force is less than zero until it reaches the first zero point of the subsequent stroke. After reaching the second zero point of the stroke, the actuating force is again zero. When the actuating force is greater than zero, it acts in the main rudder direction.
  • the force F H is preferably based on a force curve measured on a rowing boat, which can then be used as a basis for the rowing machine.
  • the resistance of the braking device must be adjusted so that the resulting force curve when rowing on the rowing machine corresponds at least approximately to the force curve measured on the rowing boat.
  • the correction factor KF is an optional factor that can be greater than zero, less than zero, or equal to zero.
  • the correction factor can be a constant or a variable that depends on the angle ⁇ or another influencing factor.
  • the correction factor can depend on the acceleration of the footplate.
  • the footplate can be slidably mounted on the frame, with the adjusting mechanism being associated with the footplate.
  • the adjusting force acts directly on the footplate.
  • the frame is fixed to the ground and does not move during rowing on the rowing machine.
  • the position of the braking device is fixed, meaning its center of gravity remains at a stationary point.
  • the braking device can be attached to the frame, which is firmly fixed to the ground. The footplate is therefore mounted so that it can slide relative to the stationary braking device.
  • the center of gravity of the The braking device should be considered stationary, even if the position of smaller parts such as pulleys etc. may change during rowing on the rowing machine.
  • the footplate and the braking device form a movable unit.
  • the footplate and the braking device can only be moved back and forth as a single block.
  • Such a movable block is disclosed, for example, in the EP 0 376 403 B1 and the US 5,382,210 .
  • the footplate can be rigidly connected to the frame, with a sliding mechanism providing the frame being slidably mounted along the main rudder direction and also in the opposite direction.
  • the adjusting device is integrated into the sliding mechanism. Since the frame and the footplate are rigidly connected, there is no relative velocity between the footplate and the frame in the main rudder direction.
  • the movement of the footplate corresponds to the movement of the frame.
  • the footplate moves relative to the frame.
  • the footplate is slidably mounted relative to a fixed point or a fixed base in the main rudder direction (and in the opposite direction).
  • the sled assembly can have a fixed frame and a sliding sled that serves to hold one of the frame's support legs.
  • two sled assemblies can be used, one sled assembly for each support leg.
  • the frame can be designed such that the sliding area of the carriage, viewed in the main rudder direction, is at least 80 cm or at least 100 cm long. Tests and calculations have shown that a sliding area with a length of 120 cm is sufficient to simulate rowing on water with ordinary forces and accelerations in the rowing machine according to the invention.
  • the actuating device can include a drive.
  • the drive comprises an electric machine that can preferably operate as both a generator and a motor during a rowing cycle.
  • An electric machine thus makes it possible to provide an actuating force that, depending on requirements, either brakes the frame (in generator mode) or drives it (in motor mode).
  • the actuating device can have traction elements by which the preferably stationary drive is connected to the carriage or the footplate. It is also possible for the drive to be arranged on the carriage or the footplate and thus move with it.
  • the drive mechanism can include a brake that slows the movement of the footplate/frame in the main rudder direction and/or in the opposite direction.
  • the braking force is adjustable and varies during a rudder cycle.
  • it can be a disc brake with a brake disc and brake shoes, where the brake shoes are pressed against the brake disc with an adjustable force.
  • the drive mechanism can include a rotating drive wheel that engages with a pulley for the traction element.
  • the drive wheel rotates, the traction element pulls on the carriage and moves it accordingly.
  • the traction element pulls on the footplate and moves it accordingly.
  • the drive mechanism does not necessarily need to include means that positively amplify the movement of the footplate in one direction.
  • the drive comprises a brake and is free of a motor that delivers positive torque.
  • the drive mechanism ensures that a resistance/braking force opposes the foot force, which can vary during the pull phase.
  • the braking force acts in the main rudder direction; that is, during the pull, the brake slows the movement of the footplate in the opposite direction to the main rudder direction.
  • the brake also slows the movement of the footplate.
  • the drive mechanism comprising only a brake and no motor, has the sole function of selectively braking or slowing the movement of the footplate caused by the oar's back-and-forth motion.
  • the traction element has an upper run and a lower run, with the upper run preferably being connected to the footplate/slide.
  • the upper run preferably extends between two spaced-apart deflection pulleys, at least one of which is driven by the drive.
  • the upper and lower runs make it possible to pull the slide or footplate towards the driven deflection pulley or, alternatively, to pull it away from the driven deflection pulley via the other deflection pulley.
  • the actuator determines the boat's propulsion force as a function of an operating characteristic of the braking device.
  • this operating characteristic could be the oar work that occurs or is performed during the braking process.
  • the operating characteristic could be a curve of the resistance force that must be overcome when moving the oar handle.
  • the boat's propulsion force could also be a curve that preferably depends on a rudder angle or a
  • the oar position depends on the oar handle (at the forward reversal point, the oar position is preferably set to 0 cm).
  • the actuating force can also include an additional component that takes into account the inertial force of a fictitious boat weight and/or a fictitious rowing crew. This allows the actuating force to further simulate the user sitting on the rowing machine in a (virtual) rowing boat with several rowers who roll back and forth during a rowing cycle, thus influencing the boat speed or the speed at which the frame or footplate moves. In this way, the rowing machine can replicate the rowing action of a larger boat with multiple rowers.
  • the component described here can be found in the optional correction factor KF described above.
  • the frame 10 has a display 12.
  • the rower 3 can read different data from the display 12, for example the stroke rate (number of rowing cycles per minute), the rowing time, the rowing power in watts and/or a calculated (fictitious) value for the rowed distance.
  • the frame 10 further comprises a first support leg 13 and a second support leg 14.
  • the first support leg 13 rests against a slide 51 of a first slide assembly 50.
  • the slide assembly 50 in addition to the slide 51, has a frame 52 on which, or in which, the slide 51 is slidably mounted.
  • the frame 52 rests firmly on the floor of a training room, rowing cellar, or the like, and is aligned with the frame 10 of the rowing machine 1 such that the sliding seat 20 and the slide 51 are slidably mounted in the same direction, namely along the main rowing direction 2.
  • a further slide assembly 60 is provided for the second support leg 14, which, like the slide assembly 50, has a fixed frame 62 and a sliding slide 61.
  • the further sled construction 60 is also aligned with respect to the frame 10 of the rowing machine 1 and the sled construction 50 in such a way that the frame 10 of the rowing machine 1 can be moved in the main rowing direction 2.
  • the carriage assembly 50 is associated with an actuating device 70, which serves to provide an actuating force with which the movement of the carriage 51, and thus the movement of the entire system, consisting of rowing machine 1 and rower 3, can be influenced.
  • the other carriage assembly 60 is not associated with an actuating device.
  • the carriage 61 should be able to move virtually without resistance relative to the stationary frame 62.
  • the actuating device 70 has, in addition to the motor 71 designed as an electric motor, a belt-shaped, rotating traction element 76.
  • An upper run 77 of the traction element 76 is divided into two parts, with the carriage 51 arranged between the two parts 77a, 77b of the upper run 77.

  • the rudder main direction 2 is between two pulleys 78, 79.
  • Pulley 78 engages with a drive wheel 80 of the electric motor 71. When the drive wheel 80 rotates, pulley 78 also rotates.
  • a lower run 81 of the traction element 76 extends continuously between pulleys 78, 79.
  • the traction element 76 can have a profile that engages in a correspondingly shaped profile on the outer circumference of the deflection pulleys 78, 79.
  • the underside can also be smooth, so that there is only a frictional connection between the traction element 76 and the deflection pulley 78. Accordingly, the traction element 76 must then be under tension so that a torque can be transmitted from the pulley 78 to the traction element 76.
  • the drive wheel 80 is in the representation of the Figure 3 As the pulley rotates clockwise (see arrow 82), the deflection pulley 78 rotates counterclockwise, whereby the upper run 77 pulls the carriage 51 towards the electric motor 71. To position the carriage 51 in the representation of the Figure 3 To move to the right, the drive gear 80 must rotate counterclockwise. This places a particular tensile load on the lower run 81.
  • the return roll is slowed by bracing the feet against the footrest 11. This force acting on the footrest 11 significantly decelerates the boat.
  • the direction of the rolling motion of the sliding seat reverses.
  • the influence of the rolling motion on the boat speed is also very high at the beginning of the first pull, as the rower now extends their legs and exerts corresponding pressure on the footrest 11.
  • the boat's resistance force and the boat's propulsive force are in equilibrium. Accordingly, the curve V ⁇ sub> AW ⁇ /sub> has a slope of zero (the acceleration due to the boat's propulsive force and the boat's resistance force is zero). Only when the oar blades encounter significant counter-pressure in the second pull, The speed profile V AW increases significantly, i.e., in this phase the boat's propulsive force is significantly greater than the boat's resistance force.
  • the footplate 11 and the brake device 40 are parts of a movable unit that can move back and forth in the main rudder direction 2 and in the opposite direction.
  • the drive 71 is also said to be part of the movable unit and moves with the footplate 11.
