Benefits of technology

The present invention is a pneumatic ab wheel that adjusts friction against a surface by adjusting pneumatic pressure. The wheel is filled with gas to form a pneumatic pressure, and when the pressure is adjusted, the frictional force between the wheel and the surface is changed. The wheel has holding sections that are sleeved by grips, and the grips have anti-slip regions. The rotation assembly has a first pivotal connection member and a second pivotal connection member assembled with the first pivotal connection member. The wheel also has an air hole through which the pneumatic pressure in the wheel is adjusted. The technical effects of the invention include adjustable friction and impedance levels for different training progress.

Problems solved by technology

However, in the above conventional ab wheels, either the elastic member or the spring rolling film is configured with a predetermined elastic force and then installed in the wheel, in a way that the elastic force of the ab wheel cannot be adjusted according to user preference or exercise intensity and progress.
Further, when used for an extended period of time, fatigue of the elastic member or the spring rolling film may be resulted, gradually failing the expected fitness function of the ab wheel.

Embodiment Construction

[0022]Details and technical contents of the present invention are given with the accompanying drawings below.

[0023]As shown in FIG. 1, FIG. 2 and FIG. 3, a pneumatic ab wheel 10 of the present invention, operable to be rolled on a surface (not shown, may be the ground, a wall surface, or any surface on which rolling can be performed) for a user to carry out a fitness exercise, includes a shaft 20, a rotation assembly 30 and a wheel 40.

[0024]The shaft 20 comprises a middle section 21, and two holding sections 22 respectively extending from the middle section 21 and towards opposite directions. Each of the holding sections 22 is sleeved by a grip 23 for hands of the user to hold onto. Each of the grips 23 is provided with an anti-slip region 231 for preventing the hands of the user from slipping off the grips 23.

[0025]The rotation assembly 30 is provided around the middle section 21 of the shaft 20 and between the two grips 23. The rotation assembly 30 is operable to perform a rotatio...

Abstract

A pneumatic ab wheel includes shaft having a middle section and two holding sections, a rotation assembly pivotally connected to the middle section of the shaft and performing a rotational movement on the shaft, and a wheel provided around the rotation assembly to drive the rotation assembly to perform the rotational movement on the shaft and to roll on a surface while in contact with the surface so as to generate a frictional force. The wheel is filled therein with at least one gas to form a pneumatic pressure in the wheel. When the pneumatic pressure in the wheel is adjusted, the frictional force between the wheel and the surface is changed.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a pneumatic ab wheel, and particularly to a pneumatic ab wheel that changes friction against a surface by adjusting a pneumatic pressure.BACKGROUND OF THE INVENTION[0002]An ab wheel is a common type of household exercise equipment, and allows a user to perform back-and-forth rolling movements on the ground to achieve a fitness effect.[0003]For example, a common ab wheel is as the Taiwan Patent No. M513713 disclosing a restoring abdominal muscle exercise machine. The restoring abdominal muscle exercise machine includes: a wheel, having therein an accommodating space and pivotally disposed on an axis, wherein at least one elastic member is provided around an inner wall of the accommodating space; and two grips, respectively provided at two ends of the axis, operable to be held by a user. When the wheel rotates clockwise, the elastic member is compressed to cause the wheel to rotate counterclockwise.[0004]For another example,...
