Multifunctional kinetic mechanism
A multifunctional kinetic mechanism includes a base including a slant tube, a counterweight unit including a joint shaft rotatably connected to the slant tube of the base, a barbell shaft having a first end piece connected to the joint shaft and a second end piece opposite to the first end piece and a counterweight attached to the second end piece of the barbell shaft, and an operating unit including a main frame, a sleeve located at a front side of the main frame and sleeved onto the second end piece of the barbell shaft, two grips respectively pivotally mounted at an opposing rear side of the main frame and two shoulder cushion pads mounted at a bottom side of the main frame between the sleeve and the two grips. Thus, a user can operate the operating unit to move the barbell shaft to train different muscle groups.
1. A multifunctional kinetic mechanism, comprising:
a base comprising a slant tube coupled to the base at a fixed acute angle relative to a horizontal support surface upon which the base is configured to be positioned;
a counterweight unit comprising a joint shaft pivotable about a horizontal axis, a barbell shaft and a counterweight, said joint shaft being detachably connected to said slant tube of said base, said barbell shaft comprising a first end piece and an opposing second end piece, said first end piece being detachably connected to said joint shaft, said counterweight being detachably attached to said second end piece of said barbell shaft; and
an operating unit comprising a main frame, a sleeve, two opposing grips and two opposing shoulder cushion pads, said sleeve being mounted at a front side of said main frame and detachably sleeved onto said second end piece of said barbell shaft, said two grips being respectively pivotally mounted at an opposing rear side of said main frame, said two shoulder cushion pads being respectively mounted at a bottom side of said main frame between said sleeve and said two grips.
2. The multifunctional kinetic mechanism as claimed in claim 1 , wherein said joint shaft comprises a first joint member rotatably inserted into said slant tube of said base, and a second joint member vertically pivotally connected to said first joint member; said first end piece of said barbell shaft is plugged into said second joint member.
3. The multifunctional kinetic mechanism as claimed in claim 1 , wherein said second end piece of said barbell shaft comprises a flange; said counterweight is attached onto said second end piece of said barbell shaft and stopped at said flange.
4. The multifunctional kinetic mechanism as claimed in claim 1 , wherein said operating unit further comprises two auxiliary handlebars disposed at two opposite sides relative to said sleeve and respectively connected with respective one ends thereof to the said bottom side of said main frame.
5. The multifunctional kinetic mechanism as claimed in claim 1 , wherein said counterweight unit further comprises an accessory rack disposed around said base, said accessory rack comprising an upright rod for supporting said operating unit, a horizontal bar for supporting said counterweight, and a support bar for supporting said barbell shaft.
