Japanese Patent JP2013500083
Kind Code:
A
Abstract:
An adjustable inertial exercise device has an elongate member with first and second threaded portions with opposite-handed threads. First and second nuts, each having at least one radial flange, are respectively rotatably engaged with the first and second threaded portions of the elongate member. A sleeve is slidably mounted over the first and second nuts. The sleeve has an internal bore with first and second bearings and at least one longitudinal groove slidably engaged with the radial flanges of the first and second nuts. Elastic resistance elements interface between the first and second nuts and the first and second bearings. Rotation of the elongate member relative to the sleeve one direction causes the nuts to move apart from one another compress the resistance elements. Rotation of the elongate member relative to the sleeve in the opposite direction causes the nuts to move toward one another and expand the resistance elements.
