Definitions

  • the present invention relates to a rope type folding mechanism for an exercise treadmill.
  • a frame of conventional treadmills (for example disclosed in US 5,674,453 and US 6,033,347) is designed to be foldable in order to reduce the occupied space and to facilitate the movement thereof.
  • these products have to include an auxiliary lifting member (like a pneumatic or oil-pressurised cylinder) behind the frame in order to prevent the frame from an unexpected collapse endangering the operator or the other around. Accordingly, the whole design and use show much inconvenience.
  • a folding device for a treadmill for example, is disclosed in US 5,746,682. Upon separation of the handle frame of this folding device a retractable pressure bar is released from compressed condition and becomes movable and extensible. With gravity of the drive motor located beneath the rear end of the treadmill body the treadmill body turns upward and, simultaneously, the handle frame is caused to fold to the surface of the treadmill body.
  • this conventional design doesn't fit the old or the disable in waist or lower limbs because they have much difficulty in bending down to perform the folding movement.
  • the object is solved according to the features of claim 1.
  • the frame can be folded to the top at an automatic locking position by means of rope wheels, strong ropes and corresponding pivots for achieving a full safety for operators and people around.
  • a preferred embodiment of the present invention mainly includes a U-shaped handrail 10, two supporting arms 20, a frame 30, a front support 40, a motorised assembly 50 and a rear treading plate 60.
  • the frame 30 has a platform 31, whereby the front and rear ends of said platform 31 are fitted with a front and rear roller 32, 33 between which a treadmill walking belt 34 circles.
  • the rear roller 33 of the frame 30 is positioned on horizontal parts 21 of the supporting arms 20 by means of a first pivot 35.
  • the motorised assembly 50 comprises a motor 51, a belt 52, a driven wheel 53 and a protection cover 54.
  • the motor 51 is fixed behind the horizontal parts 21 of the supporting arms 20 by means of a fastening member.
  • the belt 52 extends between a power output shaft 56 and the driven wheel 53 while the rear roller 33 is driven by the driven wheel 53 for a rotational movement of the treadmill walking belt 34.
  • Each end of the U-shaped handrail 10 is provided with a rope wheel 11 whose shaft 12 is pivotably mounted on the extension part 22 at the top of each of the supporting arms 20. Thereafter, a strong rope 70 is fixed at one side of the rope wheel 11 and pulled downward to the bottom 36 of the frame 30.
  • the rope wheel 11 is also rotated to pull the strong rope 70 upward.
  • the frame 30 is raised up to the top by means that the rear roller 33 is turned around the first pivot 35.
  • the frame 30 can be folded up for storage or unfolded for exercise operation only by moving the U-shaped handrail 10. Meanwhile, when the U-shaped handrail 10 is moved up to the top (see FIG. 3), the handrail 10 is considerably turned to the other side of the frame 30 in a hung state at a locked angle. Therefore, the frame 30 won't be unexpectedly collapsed even in case of being moved.
  • the frame 30 can only be lowered by moving the U-shaped handrail 10 in proper operation steps so that the safety is more ensured.
  • the strong rope 70 can be substituted by any equivalent components.
