Definitions

  • the invention relates to a treadmill, more particularly to a treadmill with an automatically foldable treadbase.
  • Treadmills are indoor exercising equipments preferred by many users.
  • conventional treadmills are difficult to store and occupy much space because of their irregular shapes and bulky sizes.
  • treadbases are difficult to manually lift to the folded state and may cause back strain or other injury.
  • Heavy treadbases are also hazardous when released from the folded state as they will rapidly fall and could injure the user.
  • the object of the present invention is to provide a treadbase that can be folded and unfolded automatically.
  • a treadmill comprises a base frame, a treadbase, a support bar unit, and a drive unit.
  • the base frame has front and rear frame ends.
  • the treadbase has front and rear base ends, and includes a treading member disposed above the base frame.
  • the support bar unit has a first bar portion pivoted to the treading member, and a second bar portion pivoted to the base frame.
  • the drive unit includes power unit mounted on the base frame, and a telescopic arm that has a front arm end coupled to the treadbase and a rear arm end connected to the power unit.
  • the drive motor is operable so as to extend forward or retract rearward the front arm end of the telescopic arm. Rearward retraction of the front arm end results in movement of the front base end toward the rear frame end and in upward folding movement of the treadbase.
  • FIG. 1 is a perspective view of the first preferred embodiment of a treadmill according to the present invention.
  • FIG. 2 is a perspective view of the first preferred embodiment with a treadbase in an upright folded state
  • FIG. 3 is a perspective view of the second preferred embodiment of a treadmill according to the present invention.
  • FIG. 4 is a schematic side view of the second preferred embodiment with a treadbase in an inclined unfolded state
  • FIG. 5 is a schematic side view of the second preferred embodiment with the treadbase in a horizontal unfolded state
  • FIG. 6 is a schematic side view of the second preferred embodiment with the treadbase in an upright folded state
  • FIG. 7 is a perspective view of the third preferred embodiment of a treadmill according to the present invention.
  • the first preferred embodiment of a treadmill according to the present invention is shown to include a base frame 1 , a treadbase 2 , a support bar unit 4 , and a drive unit 3 .
  • the base frame 1 has front and rear frame ends 114 , 113 , and includes left and right frame portions 11 and a connecting frame portion 12 that interconnects the left and right frame portions 11 at the rear frame end 113 .
  • Each of the left and right frame portions 11 has an inner surface 112 formed with a slide rail 111 that extends from the front frame end 114 toward the rear frame end 113 .
  • An upright prop 14 for mounting a control panel has a lower end portion secured to the base frame 1 at the front frame end 114 .
  • the treadbase 2 includes a treading member 20 that has left and right base portions 21 , 22 and connecting base portions 23 , 24 that interconnect the left and right base portions 21 , 22 and that serve as front and rear base ends of the treadbase 2 .
  • the treading member 20 is disposed above the base frame 1 .
  • the connecting base portion 23 is provided with rollers 34 that are coupled slidably and respectively to the slide rails 111 .
  • the support bar unit 4 includes left and right bars 41 adjacent to a respective one of the left and right frame portions 11 of the base frame 1 .
  • Each of the left and right bars 41 has a first bar portion 412 that is connected pivotally to a respective one of the left and right base portions 21 , 22 , and a second bar portion 411 that is connected pivotally to the connecting frame portion 12 of the base frame 1 .
  • the drive unit 3 includes a drive motor 33 and a telescopic arm.
  • the drive motor 33 is mounted pivotally on the connecting frame portion 12 of the base frame 1 .
  • the telescopic arm includes an internally threaded sleeve tube 31 and a screw rod 32 .
  • the sleeve tube 31 has one end which serves as a front arm end 311 of the telescopic arm and which is connected pivotally to the connecting base portion 23 of the treading member 20 .
  • the screw rod 32 is inserted threadedly and telescopically into the sleeve tube 31 and has one end that serves as a rear arm end 312 of the telescopic arm and that is connected to and driven rotatably by the drive motor 33 .
  • the drive motor 33 is operated so as to rotate axially the screw rod 32 in a clockwise direction, which causes the screw rod 32 to thread into the sleeve tube 31 .
  • This results in rearward retraction of the front arm end 311 relative to the connecting frame portion 12 .
  • This pulls the connecting base portion 23 and causes the rollers 34 to slide along the slide rails 111 toward the rear frame end 113 of the base frame 1 .
  • the treadbase 2 rotates about a pivot axis (A), which results in upward folding movement of the rear base end of the treadbase 2 , until the treadbase 2 reaches an upright folded state, as best shown in FIG. 2.
  • FIGS. 3 and 4 illustrate the second preferred embodiment of a treadmill according to the present invention.
  • the treadbase 2 of this embodiment further includes a lifting frame member 25 .
  • the lifting frame member 25 includes a pair of lifting bards 251 , each having a first frame portion 2511 and a second frame portion 2512 , and a first crossbar 253 that interconnects the second frame portions 2512 of the lifting bars 251 .
  • the first frame portions 2511 of the lifting bars 251 of the lifting frame member 25 are pivoted to the left and right base portions 21 , 22 of the treading member 20 , respectively.
  • first crossbar 253 of the lifting frame member 25 which serves as the front base end of the treadbase 2 in this embodiment, is provided with the rollers 34 for coupling slidably to the slide rails 111 of the base frame 1 .
  • the first crossbar 253 is thus movable between the front and rear frame ends 114 , 113 of the base frame 1 .
  • the front arm end 311 of the telescopic arm is connected pivotally to the first crossbar 253 of the lifting frame member 25 .
  • the treadmill further comprises a releasable fastening unit 26 for fastening immovably and selectively the lifting frame member 25 to the treading member 20 .
  • the fastening unit 26 has a first fastening lug 261 provided on the treading member 20 , a second fastening lug 262 provided on the first crossbar 253 of the lifting frame member 25 , a fastening screw 263 , and a nut 264 .
  • the fastening screw 263 and the nut 264 can be used to fasten together the lugs 261 , 262 , thereby fastening immovably the first crossbar 253 of the lifting frame member 25 to the treading member 20 .
  • the drive motor 33 can be operated so as to rotate the screw rod 32 for rearward retraction or forward extension of the front arm end 311 of the telescopic arm. This, in turn, results in sliding movement of the rollers 34 along the slide rails 111 to raise or lower the treading member 20 relative to the base frame 1 .
  • the inclination of the treadbase 2 can be varied automatically in this embodiment to suit the user's requirements.
  • FIG. 7 illustrates the third preferred embodiment of a treadmill according to the present invention.
  • the lifting frame member 25 further includes a second crossbar 254 that interconnects the left and right lifting bars 251 and that is parallel to the first crossbar 253 .
  • the front arm end 311 of the telescopic arm is connected pivotally to the second crossbar 254 of the lifting frame member 25 . Since the operation of this embodiment is similar to that described hereinabove in connection with the second preferred embodiment, a detailed description of the same will be dispensed with herein for the sake of brevity.
  • the treadmill of this invention includes a treadbase 2 that can be folded and unfolded using the drive motor 3 .
  • the inclination of the treadbase 2 can also be varied using the same motor in the second and third embodiments of this invention. Accordingly, the user can fold, unfold, and vary the inclination of the treadbase 2 of the treadmill without undue physical strain.
  • the telescopic arm and the drive motor 33 cooperate to prevent rapid falling of the treadbase 2 during an unfolding operation, thereby making the treadmill of this invention safer to use as compared with conventional treadmills.
