Title:
ROPE FOR ROPE SKIPPING
Document Type and Number:
Japanese Patent JPS6173674
Kind Code:
A
Abstract:
A jumping rope for exercising including resiliently flexible handles for adjustably altering the moment of force imposed upon the user by the swinging rope. The jump rope construction includes evenly extended handles at each end thereof. The interval between the extended handles and a ball bearing assembly within which the rope is secured comprises a resilient member which will vary the torsional force along its longitudinal axis. The rope is joined to the handle section by a ball bearing assembly which is recessed from the handle shoulder. The handle section adjacent the rope is a terminal coupling and has a tapered cross-section at the shoulder thereof to reduce the friction between the rope and the shoulder of the handle section. The opposite end of the receiving handle section is joined to a mating extension which resiliently bends along its longitudinal axis and can be easily gripped by the user. The flexiblity of the resilient member is in response to the rate of rotation of the rope and thereby changing the effective distance between the user's hand and the point at which the force of the swinging rope will be applied to the handle.
