Exercise apparatus

Abstract

Exercise apparatus including a guide and a sliding member slidably mounted to the guide, the sliding member including an operating member for allowing a user to apply first and second operating forces to the sliding member to thereby selectively slide the sliding member in respective first and second directions and a resistance mechanism for generating respective first and second resistive forces when the sliding member is moved in the first and second directions.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to an exercise apparatus and method of exercising using an exercise apparatus, and more particularly to exercise apparatus for providing variable resistance to movement.DESCRIPTION OF THE PRIOR ART[0002]The reference in this specification to any prior publication (or information derived from it), or to any matter which is known, is not, and should not be taken as an acknowledgment or admission or any form of suggestion that the prior publication (or information derived from it) or known matter forms part of the common general knowledge in the field of endeavour to which this specification relates.[0003]Numerous health benefits of exercises resulted in popularity of exercise devices, which can be used at use's convenience, including in private homes and specialised gyms. Most common types of resistance exercise equipment include upright and recumbent bikes, elliptical trainers, rowers, steppers and strength equipment. The...

AI Technical Summary

Benefits of technology

[0080]Typically the tube of the slide member includes at least two slots and respective bolts with nuts for at least one sliding brake, allowing changing position of at least one sliding brake inside the tube along the slots, allowing varying the distance between brakes; wherein the shorter distance between brakes results in jamming action between brakes and the guide rail, and resultant higher constant resistance to movement of slide member along the guide rail in both directions and vice verse; wherein the shorter distance between brakes increases mechanical advantage in the lever action during exercise stroke due shorter load arm of the lever and vice verse.

Problems solved by technology

These devices are usually heavy, bulky and expensive that is, at least in part, due to complex brake systems used in these devices.

Hydraulic resistance systems have considerable size and weight, and their resistance cannot be easily regulated.

Weight based equipment utilises force of gravity but is awkward and unsafe to use without supervision.

These properties of existing resistance systems significantly limit design of new exercise devices and new applications of existing exercise devices.

For example, existing miniature exercise devices, e.g. mini steppers and bikes, have significantly limited capabilities and are awkward to use, where miniaturization results in short distance of resisted movement (working distance).

Short working distance makes exercises confined only to small muscle groups and, therefore, not efficient.

Even standard bicycles do not provide resistance for full range of human leg extension, allowing only about 30 cm of resisted movement.

In addition, all bicycle-like devices have non-linear trajectory of resisted movements due to platform revolution and no resistance for leg flexion, e.g. no hamstring muscles load.

Other limitations of existing exercise devices are non-physiological resistance profiles, rigid regulation of resistance and non-linear trajectory of resistance movements.

Such devices do not allow the user to work at his or her maximum capabilities during that portion of movement in which the user has higher strength capabilities because muscle torque is maximal in the middle of contraction and drops towards the full muscle contraction.
