    • DETAILED DESCRIPTION OF THE INVENTION
  • As shown in FIG., a treadmill of the preferred embodiment of the present invention comprises:
  • A main member 10 includes a base 12 and a deck 34. The base 12 has a U-shaped main frame 14 and a transverse frame 16 connected to the main frame 14. The main frame 14 is provided with two stands 18 and two wheels 20 on a bottom thereof and two pivot bases 22 on a top thereof. Each of the pivot bases 22 has a U-shaped plate with an opening 24 and three bores 26, 28 and 30 (seeing FIG. 6). The main frame 14 is provided with a hook 32. The deck 34 has its front side fixed to the base 12. The deck 34 is provided with a running belt 36 to be driven by a motor (not shown).
  • Two handle bars 38 have ends pivoted on the pivot bases 22 respectively. The handle bars 38 are rotated along an axial direction d between a first position (shown in FIG. 2 and FIG. 3) and a second position (shown in FIG. 4 and FIG. 5). The handle bars 38 also are turned between an extended position (shown in FIG. 2, FIG. 3 and FIG. 4) and a folded position (shown in FIG. 5). We define an extended status of the handle bars 39 (FIG. 2) when they are at the extended position and the first position and a folded status (FIG. 5) when they are at the folded position and the second position. Each of the handle bars 38 has an arched portion 40 for user to hold when they are at the extended status. Each of the handle bars 38 has a connector 42 at free ends thereof.
  • As shown in FIG. 6, each of the handle bars 38 has two holes 44 at opposite sides and a bore 46 and a threaded bore 48 above the holes 44. Two bolts 50 are inserted through the pivot bases 22 and the holes 44 of the handle bars 38, and then are screwed into the deck 34, such that the handle bars 38 can be rotated between the first position and the second position and turned between the extended position and the folded position. Each of the handle bars 38 is provided with a lock 52, as shown in FIG. 7, which has a button 54 and a U-shaped spring portion 56. The locks 52 are received in the handle bars 39 respectively with the spring portions 56 against the handle bars 39 and the distal ends of the buttons 54 extruded out of the handle bars 39 via the bores 46. When the handle bars 39 are moved to the extended position and rotated to the first position or the second position, the buttons 54 are engaged with the bores 26 or 28 respectively to position the handle bars 38. When the handle bars 38 are moved to the extended position and rotated to the first position (the handle bars 38 are at the extended status), the threaded bores 48 of the handle bars 38 is aligned with the bores 28 of the pivot bases 22 respectively, such that user may screw bolts 58 into the bores 28 and the threaded bores 48 respectively to fix the handle bars 38 at the extended status.
  • A panel 60 has a screen, switches and buttons (not shown) thereon and has a circuit board (not shown) therein. The screen, switches and buttons are electrically connected to the circuit board, such that user can control the treadmill running by setting the switches and buttons and see some information on the screen. As shown in FIG. 8, the panel 60 has two holes (only show one of which in FIG. 8) at a back. The connectors 42 of the handle bars 38 can be inserted into the holes 62 and fixed by bolts to fix the panel 60 to the distal ends of the handle bars 38. A wire 66 is received in the handle bar 38 with opposite ends extruded out of the handle bar 38 via the opposite ends of the handle bar 38. The circuit board in the panel has a wire 72 to be electrically connected to the wire 66 via a plug 68 and a socket 70. The other end of the wire 66 is electrically connected to a circuit board (not shown) in the deck 34 that is electrically connected to the motor, such that user can control the motor by setting the switches and buttons on the panel 60.
  • FIG. 2 shows the handle bars 38 at the extended status and the panel 60 fixed on the handle bars 38. To fold the treadmill of the present invention, the panel 60 is disassembled and looses the bolts 50 first (FIG. 3). Next, rotate the handle bars 38 to the second position (FIG. 4), and then turn the handle bars 38 to the folded position and hook the handle bars 38 by the hooks 32 (FIG. 5). After above step, the treadmill of the present invention is at the folded status. When the handle bars 38 are turned to the folded positions, seeing FIG. 9, the ends of the handle bares 38 enter the openings 24 of the pivot bases 22 respectively. In practice, the handle bars 38 are moved to the second position and the folded position simultaneously. User may extend the handle bars from the folded status to the extended status by the reverse steps.
  • In conclusion, to extend and fold the treadmill of the present invention, user has to move the handle bars rather than the deck, such that children and women can afford the job. In addition, the deck of the treadmill of the present invention always lies on the ground when it is at extended status and at folded status, so that the treadmill has no risk of tip.
  • In above preferred embodiment, the treadmill is a motorized treadmill. The handle bars of the present invention may be applied to non-motorized treadmill also, which does not have the motor. Some of the non-motorized treadmill may not have the panel
