P/00/009A Section 29 AUSTRALIA Patents Act 1990 INNOVATION PATENT SPECIFICATION Invention Title: TWISTING EXERCISER Applicant: Wei-Teh Ho The invention is described in the following statement: 1 7019 TWISTING EXERCISER BACKGROUND OF THE INVENTION 1. Field of the Invention: The present invention relates to physical exercising 5 apparatus and more particularly, to a twisting exerciser. 2. Description of the Related Art: An unbalanced diet has an adverse effect upon health. Nowadays, people do more care about their health. In consequence, many exercising apparatus are recreated to fit 10 different exercising requirements. Few leg-twisting exercisers are commercially available. Commercial leg-twisting exercisers are commonly heavy and expensive, not suitable for home use. Further, because different users have different body sizes. A fixed size of physical exerciser cannot fit all users. 15 SUMMARY OF THE INVENTION The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a twisting exerciser, which is practical for a twisting exercise to train the muscles of the legs, waist, abdomen and 20 arms. It is another object of the present invention to provide a twisting exerciser, which is collapsible to reduce space occupation when not in use. To achieve these and other objects of the present 2 invention, a twisting exerciser comprises a base, which has an arched track arranged along the periphery thereof, a stem extended from the front side thereof and a stop block protruded from the convex top wall thereof at each of the two distal ends 5 of the arched track, a plurality of foot members detachably affixed to the front side of the base for supporting said base on a flat surface in a tilted position, a pivot located on the center of the convex top wall of the base, two swivel arms each having a front end pivotally connected to the pivot and a rear end 10 provided a top knee pad and a bottom roller that is coupled to the arched track of the base, and a handlebar that has one end detachably fastened to the stem of the base and the other end provided with two grips. Further, each swivel arm has an eye lug on the middle. 15 Further, a connection rod is selectively used for joining the swivel arms for synchronous movement along the arched track of the base. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a twisting exerciser in 20 accordance with the present invention. FIG. 2 is a side view of the twisting exerciser in accordance with the present invention. FIG. 3 is an exploded view of the twisting exerciser in 3 accordance with the present invention. FIG. 4 is another exploded view of the twisting exerciser in accordance with the present invention (the handlebar excluded). 5 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIGS. 1-4, a twisting exerciser in accordance with the present invention is shown comprising foot members 1 and 5, a base 2, two swivel arms 3 and a handlebar 4. 10 The base 2 is shaped like a dome, having an arched track 20 arranged along the periphery thereof and a stop block 200 protruded from the convex top wall thereof at the front side of each of the two distal ends of the arched track 20. The foot members 1 and 5 are detachably affixed to the front side of the 15 base 2 to support the base 2 on the floor in a tilted position. The swivel arms 3 are respectively pivotally connected to the center of the convex top wall of the base 2 with a pivot 22, each having a knee pad 30 located on the free end thereof and a roller 31 pivotally mounted on the bottom side of the free end 20 beneath the knee pad 30 and coupled to the arched track 20 of the base 2. Further, a stem 21 extends from the front side of the base 2 for the mounting of the handlebar 4, which has two grips 40 at the front side thereof. Further, each swivel arm 3 4 has an eye lug 32 on the middle. A connection rod 33 is detachably fastened to the eye lugs 32 of the swivel arms 3 to join the swivel arms 3 for synchronous movement along the arched track 20 of the base 2. 5 During operation, the foot members 1 and 5 are placed on the floor to support the base 2 in a tilted position, and then the handlebar 4 is attached to the stem 21. At this time, the user can rest the knees on the knee pads 30 and holds the grips 40 with the hands, and then twist the legs, the waist and the 10 abdomen to turn the swivel arms 3 back and forth about the pivot 22 in reversed directions and along the arched track 20. Further, the stop blocks 200 limit the moving range of the swivel arms 3 on the arched track 20. Repeating this exercising manner, the muscles of the legs, waist, abdomen and arms are 15 trained. Further, the user can fasten the connection rod 33 to the eye lugs 32 of the swivel arms 3 to join the swivel arms 3 for synchronous movement along the arched track 20 of the base 2. When not in use, the foot members 1 and 5 and the 20 handlebar 4 can be detached from the base 2 to reduce space occupation. Although a particular embodiment of the invention has been described in detail for purposes of illustration, various 5 modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims. 5 6
