Description

FIELD OF INVENTION

The present invention relates generally to physical training machines, and in particular, versatile exercise machines structured for exercising the abdominal muscles a user.

BACKGROUND

With the growing awareness of health problems caused by lack of exercises, popularity of exercise machines, such as stationary bicycles, treadmills, rowing machines, step climbing machines, etc., has been continuously increasing. Typically, these machines are designed to focus movements of certain parts of the body. For example, abdomen machines may be structured to induce body exercises to strengthen abdominal muscles. Existing abdomen machines, however, are usually designed based on variations of sit-up exercises. Effective abdominal exercises may require a combination of movements involving muscles in different parts of the body including waist, legs, etc. Although there are also many exercise machines practical for exercising different parts of the body, these multipurpose exercise machines are usually heavy and expensive devices.
Therefore, traditional abdomen machines are not versatile, effective and economic.

SUMMARY OF THE DESCRIPTION

An exercise machine applicable for strengthening a user's abdominal muscles can include a swivel joint assembly having a collar post perpendicularly coupled with a transverse bar in a rotatable manner around the transverse bar, a base assembly, a seat assembly, handle bar assembly and a leg support assembly to allow a user seated on the seat assembly to cause movement of the seat assembly for muscle exercises. The base assembly can have a front base frame and a rear base frame pivotally coupled with each other via the transverse bar of the swivel joint assembly. The seat assembly may be rotationally attached to a top end of the collar post. In one embodiment, the collar post may provide an axial channel to allow rotational movement of the seat assembly around the axial channel. The leg support assembly may be detachably affixed to either the front base frame or the seat assembly to allow the seat assembly to move together with the leg support assembly or separately from the leg support assembly. The handle bars may be detachably affixed to either the seat assembly or the base assembly to allow the seat assembly to move together with the handle assembly or separately from the handle assembly.
Other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

In one embodiment, front base frame 135 and rear base frame 137 may be attached pivotally via transverse bar 143, for example, via T connectors 141, 139. Collar post 145 may be perpendicularly coupled with transverse bar 143 in a rotatable manner around transverse bar 143. Seat assembly 101 may be rotatably coupled over the top end of collar post 145 via a swivel joint mechanism to allow seat assembly 101 to rotate around an axis longitudinally along collar post 145. As a result, seat assembly 101 can rotate in a three dimensional manner around at least two perpendicular axes, a first one along collar post 145 and a second one along transverse bar 143. Other joint structures allowing three dimension movements may be applicable for coupling seat assembly 101 and based assembly 105.
In certain embodiments, leg support assembly 103 may include upper section 151 extendably coupled with lower section 153 at a lower end of upper section 151. Lower section 153 can have a series of longitudinally spaced apertures 157 to selectively engage upper section 151 at one of the apertures via a locking mechanism of adjustment knob 117. Thus, the longitudinal length of leg support assembly 103 may be adjustable via adjustment knob 117. Leg support assembly 103 may be affixed at an upper end of upper section 151 to either seat assembly 101 via locking bracket 121 or front base frame 135 via locking bracket 119.
