Definitions

  • the present invention relates to a treadling exercise machine. More particularly, the present invention relates to a treadling exercise machine which has a simplified structure.
  • a conventional treadling exercise machine has a one-way oil cylinder. Since a piston rod of the one-way oil cylinder cannot return to an original position of the piston rod after the piston rod is extended, a plurality of additional elements are required in order to force the piston rod returns to its original position.
  • An object of the present invention is to provide a treadling exercise machine which has an oil cylinder having a piston rod that can return to an original position of the piston rod after the piston rod is extended.
  • a first treadling exercise machine comprises a main frame 3, a first treadle plate 4, a second treadle plate 4', two connection seats 6, a first fixed seat 5, a second fixed seat 5', a first oil cylinder 1, and a second oil cylinder 1'.
  • the first oil cylinder 1 has a hollow main body 22, a piston 18 inserted in the hollow main body 22, a chamber 25 defined by the piston 18 and the hollow main body 22, a spring 12 disposed in the chamber 25, a piston rod 21 inserted in the hollow main body 22, an oil return aperture 11 formed in the piston 18, an oil throttle plate 17 disposed on the piston 18 to cover the oil return aperture 11, an oil throttle seat 16 disposed on the piston 18, a spring receiving seat 15 disposed on the oil throttle seat 16, and a nut 14 disposed on the spring receiving seat 15.
  • the hollow main body 22 has a distal end 24.
  • An oil seal 20 is disposed in the distal end 24 of the hollow main body 22.
  • a guide cushion 19 is disposed on the oil seal 20.
  • the piston rod 21 passes through the oil seal 20 and the guide cushion 19.
  • a proximal end of the piston rod 21 passes through the piston 18, the oil throttle seat 16, and the spring receiving seat 15.
  • the nut 14 fastens the proximal end of the piston rod 21.
  • a positioning rod 26 is disposed on a proximal end of the hollow main body 22.
  • a movable rod 27 is disposed on a distal end of the piston rod 21.
  • the hollow main body 22 contains a hydraulic oil 13.
  • the structure of the second oil cylinder 1' is the same as the structure of the first oil cylinder 1.
  • the second oil cylinder 1' comprises a piston shaft 21'.
  • connection seats 6 are disposed on a bottom of the main frame 3.
  • the first treadle plate 4 and the second treadle plate 4' are disposed on an upper portion of the main frame 3.
  • the first fixed seat 5 is disposed on the first treadle plate 4.
  • the second fixed seat 5' is disposed on the second treadle plate 4'.
  • connection seats 6 are connected to the respective first oil cylinder 1 and the respective second oil cylinder 1'.
  • the piston rod 21 is connected to the first fixed seat 5.
  • the piston shaft 21' is connected to the second fixed seat 5'.
  • An oil passage 10 is formed between the piston 18 and the oil throttle plate 17.
  • the first fixed seat 5 has a first through slot 50.
  • the second fixed seat 5' has a second through slot 50'.
  • a first positioning seat 7 replaces the first fixed seat 5.
  • a second positioning seat 7' replaces the second fixed seat 5'.
  • the first positioning seat 7 has two oblong apertures 71 and a through aperture 70.
  • the structure of the second positioning seat 7' is the same as the structure of the first positioning seat 7.
  • connection mount 8 replaces the connection seat 6.
  • connection mount 8 replaces the connection seat 6 and a positioning seat 7 replaces the fixed seat 5.
  • a fixed mount 90 replaces the connection seat 6.
  • the fixed mount 90 has two lateral arms 901, two round holes 900, and two positioning rods 902.
  • a fixed mount 90 replaces the connection seat 6 and a positioning seat 7 replaces the fixed seat 5.
  • a fixed mount 90 replaces the connection seat 6 and a connection block 91 disposed on the main frame 3.
  • the connection block 91 has two oblong holes 910 receiving a shaft 911.
  • a U-shaped seat 914 clamps the shaft 911.
  • the shaft 911 has a threaded aperture 912.
  • the U-shaped seat 914 has a threaded hole 915 matching the threaded aperture 912 of the shaft 911.
  • the U-shaped seat 914 is connected to an end of the movable rod 27.
  • An adjustment screw rod 913 fastens the shaft 911 and the U-shaped seat 914 together via the threaded aperture 912 of the shaft 911 and the threaded hole 915 of the U-shaped seat 914.
  • a C-shaped cushion 916 surrounds the adjustment screw rod 913.
