Arrangement and method for adjusting load in training equipment
The invention concerns an arrangement for adjusting load in training equipment. The arrangement comprises a load unit, an elongated guideway along which the load unit is arranged to move, a locking device with which the load unit is secured into a position corresponding the desired load of the training equipment, and a connector with which the guideway is pivotally connected to the training equipment via a fulcrum. The guideway is connected both to the moving arm and to a frame of the training equipment via the fulcrum. The invention further concerns a method for adjusting load in training equipment.
1. An arrangement for adjusting load in training equipment comprising at least one moving arm pivotably connected to a frame, the arrangement comprising a fulcrum having a first side and a second side, wherein the first side and the second side are defined on opposite sides of the frame, at least one load unit, an elongated guideway extending to either side of the fulcrum and along which the load unit is arranged to move, a locking device with which the load unit is secured into a locking position corresponding to a desired load of the training equipment, and a connector with which the guideway is pivotally connected to the training equipment via the fulcrum, the guideway being connected both to the moving arm and to a frame of the training equipment via the fulcrum, wherein the load unit is movable along the guideway to a locking position in which a center of gravity of the load unit is on the first side of the fulcrum and to a locking position in which the center of gravity of the load unit is on the second side of the fulcrum.
2. The arrangement according to claim 1 , wherein the load unit comprises a monolithic weight, at least one actuator with which the load unit is moved along the guideway, and a cover.
3. The arrangement according claim 1 , wherein the locking device is arranged directly onto the load unit.
4. The arrangement according to claim 1 , wherein the locking device comprises a gripping part for manually moving the load unit along the guideway, an arm arranged to extend inside the load unit through a cover, an attaching element with which the arm is attached pivotably to the cover, and an end part at the end of the arm, the end part attachable into a counterpart of a plurality of counterparts arranged on the guideway.
5. The arrangement according to claim 4 , wherein the end part and the counterpart form a form-lock when the load unit is secured into a position.
6. The arrangement according to claim 4 , wherein the counterparts are a series of pre-determined locking positions corresponding to the desired load of the training equipment unit.
7. The arrangement according to claim 4 , wherein the locking device is spring-loaded so that the end part is automatically secured into one counterpart in case the locking device is unintentionally set into a position between two adjacent counterparts.
8. The arrangement of claim 1 , wherein the guideway is pivotably connected to the frame at the fulcrum directly by the connector.
9. The arrangement of claim 1 , wherein the guideway and the moving arm share the same fulcrum.
10. A method for adjusting load in training equipment comprising at least one moving arm pivotably connected to a frame, a fulcrum having a first side and a second side, wherein the first side and the second side are defined on opposite sides of the frame, at least one load unit, an elongated guideway extending to either side of the fulcrum through which the guideway and the moving arm are connected to the frame and along which the load unit is arranged to move, a locking device with which the load unit is secured into a locking position corresponding to a desired load of the training equipment, and a connector with which the guideway is connected pivotally to the training equipment via the fulcrum, wherein the load unit is moved on the guideway to a locking position in which a center of gravity of the load unit is on the first side of the fulcrum and to a locking position in which the center of gravity of the load unit is on the second side of the fulcrum.
11. The method according to claim 10 , wherein the load unit is secured to one of a plurality of pre-determined locking positions arranged onto the guideway to adjust the load in stepwise manner within the pre-determined locking positions.
