Device to balance application of force
View Patent ↗A training device may include a left-side actuator to receive a user's left-sided force at a proximate end thereof; a right-side actuator to receive a user's right-sided force at a proximate end thereof; and a fulcrum that may be attached equidistant to a distal end of the left-side actuator and a distal end of the right-side actuator, to facilitate equal application of force from the user on the left actuator and the right actuator.
1. An adjunct training device, comprising:
a main frame configured to detachably mount on to a rowing machine having a seat, a left foot pedal, and a right foot pedal;
a fulcrum attached to a backside of the main frame;
a main lever that is centrally and pivotally connected to the fulcrum;
a laterally-disposed left-side actuator, including:
a proximate end configured to receive a user's left-sided force applied by the user sitting on the seat to the left foot pedal, and
a distal end attached to a left end of the main lever; and
a laterally-disposed right-side actuator, including:
a proximate end configured to receive a user's right-sided force applied by the user sitting on the seat to the right pedal, and
a distal end attached to a right end of the main lever,
wherein the main lever is configured to pivot on the fulcrum in response to unequal application of the user's left-sided force on the left side actuator and the user's right-sided force on the right side actuator, the pivoting of the main lever longitudinally moving each of the left-side actuator and the right-side actuator relative to the main frame, the longitudinal moving of the left-side actuator and the right-side actuator configured to facilitate an equal application of force from the user on the left side actuator and the right side actuator.
2. The adjunct training device of claim 1 , wherein the main frame includes:
a left-side plate having a rail disposed on an exterior side thereof along which the left-side actuator longitudinally glides; and
a right-side plate having a rail disposed on an exterior side thereof along which the right-side actuator longitudinally glides, the exterior of the left-side plate and the exterior of the right-side plate facing in opposite directions,
wherein the rail of the left-side plate and the rail of the right-side plate are symmetrically aligned and in parallel to each other.
3. The adjunct training device of claim 2 , wherein the left-side plate and the right-side plate are disposed between the left-side actuator and the right-side actuator.
4. The adjunct training device of claim 1 , wherein the fulcrum is further configured to facilitate an equal application of force from the user's left sided force on the left side actuator and the user's right sided force on the right side actuator by pivoting the main lever to move each of the left side actuator and the right side actuator, the moving of each of the left side actuator and the right side actuator configured to provide leverage to counter-balance the user's left sided force applied to the left side actuator and the user's right sided force applied to the right side actuator.
5. The adjunct training device of claim 1 , wherein when mounted to the rowing machine, the pivoting of the main lever is configured to move one of the left-side actuator and the right-side actuator away from the user sitting on the seat and to move the other one of the left-side actuator and the right-side actuator closer to the user sitting on the seat.
6. The adjunct training device of claim 1 , wherein the pivoting of the main lever includes moving one of the left pedal and the right pedal in a distal direction and moving the other one of the left pedal and the right pedal in a proximate direction.
7. The adjunct training device of claim 1 , further comprising:
damping arms that are configured to:
connect the main lever to the main frame, and
provide resistance to the pivoting of the main lever on the fulcrum.
8. The adjunct training device of claim 1 , wherein the pivoting of the main lever includes:
longitudinally moving one of the left-side actuator and the right-side actuator in a proximate direction relative to the seat of the rowing machine, and
longitudinally moving the other one of the left-side actuator and the right-side actuator in a distal direction relative to the seat of the rowing machine, the distal direction being opposite to the proximate direction.
9. The adjunct training device of claim 1 , wherein the pivoting of the main lever includes moving one of the left pedal and the right pedal in a distal direction relative to the seat and moving the other one of the left pedal and the right pedal in a proximate direction relative to the seat.
10. The adjunct training device of claim 1 , wherein the fulcrum is further configured to facilitate an adjustment due to an unequal stronger application of force on either of the left side actuator or the right side actuator, respectively, by pivoting the main lever to force the other of the right side actuator or the left side actuator, respectively, towards the user.
