Multifunctional Fitness Apparatus

Abstract

A multifunctional fitness apparatus contains: a base including a rolling disc and a rotating disc; a first guide rail set; a seat connected with the base and including two connecting shafts; a second guide rail set and a third guide rail set connecting with the two shafts axially; a first pedal set and a second pedal set coupling with the second guide rail set and the third guide rail set; and the first pedal set including a first post, a first handle, and a first roller; the second pedal set including a second post, a second handle, and a second roller. Thereby, the user holds the first handle and the second handle by two hands and kneels, sits, or stands on the first pedal set and the second pedal set to exercise.

What is claimed is: 
     
         1 . A multifunctional fitness apparatus comprising:
 a base including a rolling disc disposed on an upper side thereof and a rotating disc arranged on the rolling disc, wherein the rotating disc allows rotating in a clockwise direction and in an anti-clockwise direction so that a user kneels, sits, or stands on the rotating disc to exercise;   a first guide rail set;   a seat connected with the base by ways of the first guide set and including two connecting shafts;   a second guide rail set and a third guide rail set, the two shafts axially connecting with the second guide rail set and the third guide rail set;   a first pedal set and a second pedal set, the second guide rail set and the third guide rail set coupling with the first pedal set and the second pedal set; and   the first pedal set including a first post mounted on a free end thereof, a first handle fitted on the first post, and a first roller fixed on a bottom surface of the free end thereof;   the second pedal set including a second post mounted on a free end thereof, a second handle fitted on the second post, and a second roller fixed on a bottom surface of the free end thereof; such that the user holds the first handle and the second handle by two hands and kneels, sits, or stands on the first pedal set and the second pedal set to exercise.   
     
     
         2 . The multifunctional fitness apparatus as claimed in  claim 1 , wherein the base also includes a fixing member fixed thereon, and the fixing member has a rotary knob secured on a bottom end thereof and connecting with the base so as to drive a crank and a connection stem by which a fixed stem is driven to position the rotating disc. 
     
     
         3 . The multifunctional fitness apparatus as claimed in  claim 1 , wherein the first post allows expending and retracting to adjustably change its height. 
     
     
         4 . The multifunctional fitness apparatus as claimed in  claim 1 , wherein the first guide rail set includes two first rails, a first rod, and a first positioning mechanism; the two first rails are mounted in the base, and each first rail has a plurality of orifices defined thereon and spaced apart from each other equidistantly; one end of the first rod is fixed to the seat, the first rod slides between the two first guide rails; the first positioning mechanism is mounted on a free end of the first rod and has two first balls extending out of one of the plurality of orifices, a first conical projection pushed by a first spring to keep its first largest segment abutting against the two first balls, a unlock button for driving a first peg by which the first conical projection is driven to move and press the first spring, and the first conical projection further moves toward a first smallest segment to unlock the two first balls so that the two first balls retract inwardly to adjust a position of the seat and the first rod, thereafter the unlock button is released so that the first spring is biased against the first conical projection back to an original position, such that the two first balls position one of the plurality of orifices, thus fixing the seat. 
     
     
         5 . The multifunctional fitness apparatus as claimed in  claim 1 , wherein the second guide set includes two second rails and a second rod; and the third guide set includes two third rails and a third rod; each of the two second rails and the two third rails has a plurality of holes defined thereon and spaced apart from each other equidistantly; one end of the second rod is fixed to a front end of a first pedal, and one end of the third rod is fixed to a front end of a second pedal, two front ends of the first pedal and the second pedal are axially connected with the two connecting shafts of the seat; the second rod and the third rod slide between the two second rails and the two third guide rail; two second positioning mechanisms are disposed on two free ends of the second rod and the third rod, and each second positioning mechanism has two second balls extend out of one of the plurality of holes, a second conical projection pushed by a second spring to keep its second largest segment biasing against the two second balls, and a unlocking loop for driving a second peg to move the second conical projection and to push the second spring, such that the second conical projection moves toward a second smallest segment to unlock the two second balls so that the two second balls retract inwardly to adjust a position of the first pedal set, the second pedal set, the second rod, and the third rod, thereafter the unlocking loop is released so that the second spring pushes the second conical projection back to an original position, hence the two second balls position one of the plurality of holes so to fix the first pedal set and the second pedal set. 
     
     
         6 . The multifunctional fitness apparatus as claimed in  claim 1 , wherein the first post is set at least three heights based on the user's low posture, sitting posture, and standing posture in exercise. 
     
     
         7 . The multifunctional fitness apparatus as claimed in  claim 1 , wherein the first post and the second post include a plurality of counterweight block disposed thereon to match with a damping effect, thus increasing exercise result.
