Abstract
An equilibrium training device mainly comprises a chassis, a crank component, a pedal and a revolving inertia auxiliary roller set. When the user stands on the pedal for rotary equilibrium training, the belt and the first/second rollers of the revolving inertia auxiliary roller set are pulled together in tune with the rotation of the flywheel, so the swinging uncertainty of the pedal in revolution could be eliminated, such that the pedal could swing smoothly via the inertia of its swinging path, thus avoiding falls due to loss of equilibrium and improving greatly the security, convenience and practicability.

- 1. Field of the Invention
- The present invention relates generally to a equilibrium training device, and more particularly to an innovative one which is designed to remove uncertain swinging of the pedal during inertia action of the swinging pedal.
- 2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
- With the change of living patterns of the general public, their time and willingness for regular outdoor activities declines accordingly. For this reason, a variety of indoor fitness equipment, such as commonly-used treadmills, rowing machines or equilibrium training devices, have been developed to simulate various outdoor sports. The present invention is intended to explore how to make a breakthrough progress based on conventional equilibrium training mechanisms.
- An equilibrium training device is exclusively used for equilibrium training, for example, when simulating surfing. A conventional equilibrium training device generally comprises a chassis, pedal set over the chassis and a linking mechanism set between the chassis and pedal. With use of the linking mechanism, the pedal could swing in a manner that the users could stand on the pedal to train their equilibrium sense in tune with the controlled swinging of the pedal. Yet, as the swinging of the pedal of conventional equilibrium training device is controlled by the equilibrium action of the users, the swinging path is free of inertia and the swinging motion is of uncertainty. Moreover, given poorer equilibrium sense of the users, it is very difficult to control the standing behavior on the pedal, leading to possible falls or even injury. Also, the users may depress their willingness, resulting in lower practicability and value.
- Thus, to overcome the aforementioned problems of the prior art, it would be an advancement if the art to provide an improved structure that can significantly improve the efficacy.
- Therefore, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
- Based on the unique structure of the present invention wherein the “equilibrium training device” mainly comprises a chassis, a crank component, a pedal and a revolving inertia auxiliary roller set, when the user stands on the pedal for rotary equilibrium training, the belt and the first/second rollers of the revolving inertia auxiliary roller set are pulled together in tune with the rotation of the flywheel, so the swinging uncertainty of the pedal in revolution could be eliminated, such that the pedal could swing smoothly via the inertia of its swinging path, thus avoiding falls due to loss of equilibrium and improving greatly the security, convenience and practicability.

FIGS. 1-4 depict preferred embodiments of an equilibrium training device of the present invention, which, however, are provided for only explanatory objective for patent claims. - Said
equilibrium training device 05 comprises achassis 10, defined into a preset seating pattern to form at least a plurality ofseating portions 11. Apin joint portion 12 is additionally arranged on the preset location of thechassis 10. - A
crank component 20 is provided and comprises of afirst coupling portion 21 and asecond coupling portion 22 in displaced configuration. Of which, thefirst coupling portion 21 is pivoted onto thepin joint portion 12 of thechassis 10, such that thesecond coupling portion 22 could swing by taking thefirst coupling portion 21 as the rotary pivot. - A
pedal 30 is pivoted onto thesecond coupling portion 22 of thecrank component 20. Based on the connection between thesecond coupling portion 22 and thepedal 30, thepedal 30 can swing in a transverse circular revolution by at least taking thefirst coupling portion 21 as the rotary pivot (indicated by arrow L1 inFIG. 4 ), or thepedal 30 can swing in an autorotation motion by at least taking thesecond coupling portion 22 as the rotary pivot. - A revolving inertia
auxiliary roller set 40 is set between thechassis 10 andpedal 30, comprising of at least afirst roller 41, asecond roller 42, aflywheel 43 and abelt 44 wound between the first andsecond rollers first roller 41 and thefirst coupling portion 21 of thecrank component 20 are assembled coaxially (e.g. by welding), such that thefirst roller 41 could rotate synchronously with the revolution of thepedal 30. Of which, thesecond roller 42 is pivoted onto thechassis 10 at one side of thefirst roller 41, while theflywheel 43 and thesecond roller 41 are assembled coaxially. When thefirst roller 41 is rotated, thebelt 44 is linked with thesecond roller 42 andflywheel 43, so thebelt 44 and the first/second rollers flywheel 43, and the swinging path of thepedal 30 is of inertia. - Based on above-specified structure, when the user stands on the
pedal 30 to train their equilibrium sense (i.e. the swinging of thepedal 30 is controlled by the equilibrium motion of the human body), thebelt 44 and the first/second rollers auxiliary roller set 40 are pulled together in tune with the rotation of theflywheel 43, so the swinging uncertainty of thepedal 30 in revolution could be eliminated, such that thepedal 30 could swing smoothly via the inertia of its swinging path. Furthermore, the user with poorer equilibrium could easily control the pedal for training, avoiding possible injury from fall down due to loss of equilibrium, and also meeting the training demands of various users with improved security, convenience and practical value. - Referring to

Or, referring toFIGS. 5 and 6 , the axial direction of thesecond coupling portion 22 is oblique in relation to the ground level, so thepedal 30 is obliquely assembled in relation to thesecond coupling portion 22. Of which, when the axial direction of thesecond coupling portion 22 is oblique in relation to the ground level, thepedal 30 could swing in multiple directions in revolution or autorotation by the linking of thesecond coupling portion 22 and the pedal 30 (indicated by arrow L2 inFIG. 6 ). - Referring to
FIGS. 2 and 3 , at least an elasticauxiliary member 50 is set between thepedal 30 andchassis 10. Both ends of said elasticauxiliary member 50 are separately linked to thechassis 10 andpedal 30, allowing to limit thepedal 30 for only proper autorotation. During revolution of thepedal 30, the swinging stability and security of thepedal 30 could be improved by the auxiliary pulling action of the elasticauxiliary member 50. Further, the elasticauxiliary member 50 is preferably implemented by or not limited to either of elastic rope, spring or elastic rod. - Referring to
FIG. 7 , asoft gasket 60 is covered onto the surface of thepedal 30. Saidsoft gasket 60 is made of rubber, silica gel or soft plastics, or even latex or leather, etc. In addition,massage bulges 61 can be set on the surface of thesoft gasket 60, generating a massage effect when the user stands on thepedal 30 for equilibrium training. On the other hand, thepedal 30 of the present invention could be designed into an arced pattern, so that when thepedal 30 swings in a transverse circular revolution, the users are allowed for surfing-like equilibrium training activities, so as to improve the diversification in operation.
