Abstract: An exercise assisting device comprises steps, a step driving means, and a movable range variation means. The steps are provided for bearing the user's feet, respectively. The step driving means is configured to move the steps so as to provide the exercise to the feet on the steps. The movable range variation means is configured to expand a movable range of the steps according to weight applied to the steps, whereby an additional movable range is added to the movable range, said movable range is determined by the step driving means. The movable range variation means is configured to generate resistive force when the steps are located in the additional movable range. The movable range variation means is configured to apply the resistive force to the steps such that the resistive force cancels the weight applied to the steps.

Abstract: An exercise aiding apparatus has: a step (2) on which user's foot can be placed; a step driving means (5) for causing the step (2) to move, and causing thereby the foot placed on the step to exercise; and a motion allowable zone modifying means for expanding a motion allowable range of the steps (2) established by the step driving means in accordance with a load acting on the step (2). The motion allowable range of the step (2) is expanded when the user intentionally increases the load acting on the step (2).

Abstract: In a signal processor 18, a calculation unit 181 calculates a center point of a load applied to a left-footrest on the basis of partial loads detected by left foot load sensors 160 and 161, and calculates a center point of a load applied to a right-footrest on the basis of partial loads detected by right foot load sensors 170 and 171. A judgment unit 183 measures a deviation between each of the center points calculated by the calculation unit 181 and the center point indicated by ideal characteristic curve stored in a storage unit 182. The judgment unit 183 determines a normal exercise when the both deviations are less than a predetermined threshold (5% of a distance from an original point to the center point indicated by the ideal characteristic curve). The judgment unit 183 determines an abnormal exercise when at least one of the deviations is not less than the predetermined threshold. A control unit 180 counts the number of times the deviation is not less than the predetermined threshold.

Abstract: A riding mower comprises a raising and lowering mechanism (30, 33, 100), the raising and lowering control lever (27), and a PTO mechanism (17a, 17b) operated by a clutch lever (29). When the raising and lowering mechanism (30, 33, 100) reaches a predetermined height, a operatively connecting mechanism (5) transmits, to the raising and lowering control lever (27), a return-to-neutral displacement for returning the raising and lowering control lever (27) to the neutral position, and transmits, to the clutch lever (29), a disengaging displacement for returning the clutch lever (29) to the disengage position. A first adjusting operation member (55a) adjusts a triggering displacement at which the raising and lowering displacement is transmitted to the raising and lowering control lever (27) as the return-to-neutral displacement.

Abstract: A housing 1 is provided with a left foot support 2a and a right foot support 2b respectively for mounting user's left foot and right foot. The left foot support 2a and the right foot support 2b are respectively driven to move along a rail which defines a travel path. The housing 1 is provided with a motor 31 having an output shaft 31a which generates a rotary motion which is distributed into two routes by a worm gear 32a and two worm wheels 32b. Rotary motions of each of the worm wheels 32b are respectively transmitted to the left foot support 2a and the right foot support 2b by a crank rod 38, thereby the rotary motions of each of the worm wheels 32b act as driving forces which respectively reciprocate the left foot support 2a and the right foot support 2b. Accordingly, this configuration makes it possible to provide an exercise assisting device being configured to stimulate leg muscles by only one driving force for generation of the driving forces.
