Description
- The present invention is related to an ascending/descending and folding structure for running exerciser. The inclination of the running board can be electrically adjusted and the running board can be electrically folded. In the case that there is no power supply, a user can directly manually turn the running board upward and fold the running board.
- FIG. 13 shows a conventional running exerciser including a
base seat 50 and a runningboard frame 51 pivotally mounted on thebase seat 50. Opposite caster supports 52 are pivotally mounted on rear end of the runningboard frame 51. A linkingmechanism 53 is drivingly connected between the caster supports 52 and thebase seat 50. The linkingmechanism 53 via amotor 531 is pivotally mounted on thebase seat 50. Themotor 531 serves to drive a threadedrod 532. - The
motor 531 drives the threadedrod 532 to operate the caster supports 52 at rear end of the runningboard frame 51 and thus change the inclination thereof. When a user desires to fold 25 the runningboard frame 51 to reduce the occupied room, the user must manually turn the runningboard frame 51 upward as shown in FIG. 14. The runningboard frame 51 is quite heavy so that such procedure is very unsuitable for those having insufficient strength, such as an old man and a rehabilitated patient. - FIG. 15 shows another type of running exerciser in which a driving motor (not shown) is mounted on the
base seat 60 for driving the running belt to revolve. A folding unit is disposed under the runningboard frame 61. The folding unit includes amotor 62 for driving a threadedrod 621 to rotate. In addition, an inclination unit is provided for driving the runningboard frame 61 to adjust the inclination. The inclination unit has another motor (not shown) mounted on thebase seat 60. The motor drives atelescopic rod 63 which is linked with the caster supports 64 under the runningboard frame 61. Accordingly, the inclination of the runningboard frame 61 can be adjusted. - The above structure is able to electrically adjust the inclination of the running board frame and fold the running board frame as shown in FIG. 16. The structure includes two motors respectively for driving the caster supports64 to change the inclination of the running
board frame 61 and for folding the runningboard frame 61. In addition, the structure further includes a motor for driving the running belt. Therefore, the structure totally has three motors so that the cost for the structure is high. Moreover, the structure further includes reducing gear case, threaded rod, etc. so that the structure is relatively complicated. Furthermore, such structure lacks function of manual folding. In case there is no power supply, the user will be unable to fold the running board frame and the running exerciser will occupy much room. - FIG. 17 shows still another type of conventional running exerciser in which a
motor 72 is disposed on a pivot section of the runningboard 70 and therail 71. Themotor 72 serves to drive a threadedrod 73 to rotate. One end of the threadedrod 73 is pivotally connected with apivot point 74. When the threadedrod 73 is driven by themotor 72, the threadedrod 73 pushes thepivot point 74 to fold the runningboard 70. - The above structure includes one
single motor 72 for driving the runningboard 70 to electrically fold the same as shown in FIG. 18. Moreover, in case there is no power supply, the runningboard 70 can be manually folded. However, the force arm for themotor 72 to drive the threadedrod 73 is shorter, while the force arm from the runningboard 70 to thepivot point 74 is longer. Therefore, the load between themotor 72 and the threadedrod 73 is greater and themotor 72 is likely to damage. Furthermore, it is necessary to use amotor 72 with greater power so that the cost is relatively high. In addition, there is little space below the runningboard 70. In the case that a larger motor is used, the space will be insufficient to receive the motor. Also, such structure is unable to electrically change the inclination of the running board. An additional motor is required for achieving such function. This also increases the cost. - It is therefore a primary object of the present invention to provide an ascending/descending and folding structure for running exerciser. The running board frame is connected with a linking mechanism and driven thereby. A telescopic tube assembly of a supporting device is telescoped so as to move the caster support back and forth for adjusting the inclination of the running board. By means of rotating a threaded rod, a long sleeve of the linking mechanism is telescoped into a short sleeve, whereby the running board frame is turned upward. Therefore, the running board can be electrically folded. In the case that there is no power supply, a user can directly manually turn the running board upward and fold the running board.

- Please refer to FIGS.1 to 4. The ascending/descending and folding structure for running exerciser of the present invention includes a
base seat 10 and a runningboard frame 20 pivotally mounted on thebase seat 10. The runningboard frame 20 is connected with a supportingdevice 30 which is drivingly connected with a linkingmechanism 40, whereby the runningboard frame 20 can be inclined by different angles. - The
base seat 10 is substantially rectangular. Twoupright frames 11 are respectively disposed on two sides of thebase seat 10. Anupright column 12 is fitted in eachupright frame 11. Arail 14 having acontroller 13 is connected between the twoupright columns 12. - The running
board frame 20 is a rectangular frame body composed of four beam members connected with each other. The front end of the runningboard frame 20 is pivotally mounted between the twoupright frames 11 of thebase seat 10. Afirst hinge 21 is fixed on the runningboard frame 20. A runningboard 22 is disposed on the runningboard frame 20. A runningbelt 23 is wound on the runningboard 22 and driven by afirst motor 24 to revolve on the runningboard 22. - The
linking mechanism 40 includes a supportingdevice 30 and a power telescopic rod. The supportingdevice 30 has two opposite caster supports 31 which are respectively pivotally mounted on the runningboard frame 20 in predetermined opposite positions. Afirst beam 32 is connected between the two caster supports 31. Asecond hinge 33 is fixed on thefirst beam 32. Twocasters 34 are respectively mounted under the bottoms of the two caster supports 31. One of the caster supports 31 is further connected with atelescopic tube assembly 35. One end of aninner tube 351 of thetelescopic tube assembly 35 is fixed on thecaster support 31. One end of anouter tube 352 of thetelescopic tube assembly 35 is pivotally mounted on thebase seat 10. Thetelescopic tube assembly 35, thebase seat 10, thecaster support 31 and the runningboard frame 20 form a four-link mechanism A. The length of theinner tube 351 telescoped into theouter tube 352 is changeable so as to change the angle of thecaster support 31, whereby the inclination of the runningboard frame 20 can be adjusted. - In this embodiment, the power telescopic rod via a
second motor 41 is pivotally mounted on thefirst hinge 21 of the runningboard frame 20. Thesecond motor 41 has a threadedrod 42 fitted in ashort sleeve 43 connected with thesecond motor 41. Along sleeve 44 is fitted in theshort sleeve 43. A locatingblock 441 is disposed at one end of thelong sleeve 44. The locatingblock 441 has aninner thread 442 in which the threadedrod 42 is screwed. The other end of thelong sleeve 44 is pivotally mounted on thesecond hinge 33 of thefirst beam 32. By means of rotating the threadedrod 42 of thesecond motor 41, thelong sleeve 44 can move within theshort sleeve 43 so as to ascend or descend the runningboard frame 20. - Please refer to FIGS. 5 and 6. A user can press a press button (not shown) on the
controller 13 to make thefirst motor 24 drive the runningbelt 23 to revolve on the runningboard 22. The user can run and exercise on the runningbelt 23. In addition, by means of pressing an inclination adjusting button on thecontroller 13, thesecond motor 41 is powered to drive the threadedrod 42 to rotate. The threadedrod 42 drives the locatingblock 441 of thelong sleeve 44 and makes thelong sleeve 44 move toward theshort sleeve 43. At the same time, thefirst beam 32 of the supportingdevice 30 is driven to pivot thecaster support 31. At this time, theinner tube 351 of thetelescopic tube assembly 35 is telescoped into theouter tube 352 so as to change the inclination of the runningboard 22 on the runningboard frame 20. After the runningboard 22 reaches a position of a desired inclination, the user stops pressing the press button and the electric adjustment of inclination of the runningboard 22 is completed. - Please refer to FIGS.7 to 9. After the user completes the running exercise, the user can press a running board folding button on the
controller 13 to make thesecond motor 41 drive the threadedrod 42. The threadedrod 42 is rotated to drive the locatingblock 441 of thelong sleeve 44 and make thelong sleeve 44 move toward theshort sleeve 43. At the same time, thefirst beam 32 of the supportingdevice 30 is driven to pivot thecaster support 31. At this time, theinner tube 351 of thetelescopic tube assembly 35 is entirely telescoped into theouter tube 352 so that the angle of thecaster support 31 cannot be further changed. Under such circumstance, the runningboard frame 20, thebase seat 10, thetelescopic rod 30 and thecaster support 31 form a parallel four-link mechanism. By means of rotating the threadedrod 42 of thesecond motor 41, thelong sleeve 44 is further telescoped into theshort sleeve 43. The runningboard frame 20 is turned upward about the pivot point of the upright frames 11 of thebase seat 10 until the runningboard frame 20 and thebase seat 10 contain a 90 degree angle. At this time, the electric folding of the runningboard 22 is completed. Thereafter, the threadedrod 42 of thesecond motor 41 is fixed so that thelong sleeve 44 is truly pulled and located to prevent the runningboard frame 20 from falling down. - Referring to FIGS.10 to 12, in the case that there is no power supply and the user desires to fold the running
board 22, the user can directly use his/her hands to turn the rear end of the runningboard frame 20 upward about the pivot section of the runningboard frame 20 and thebase seat 10. With a 90 degree angle contained between the runningboard frame 20 and thebase seat 10, a locatingbolt 36 is passed through thetelescopic tube assembly 35 to lock theinner tube 351 with theouter tube 352 without telescoping. At this time, the runningboard frame 20 is fixed in a folded state. Accordingly, in the case that there is no power supply, a user can still conveniently manually fold the running board. - In conclusion, in the ascending/descending and folding structure for running exerciser of the present invention, the running board frame is connected with a linking mechanism and driven thereby. A telescopic tube assembly of a supporting device is telescoped so as to move the caster support back and forth for adjusting the inclination of the running board. By means of rotating a threaded rod, a long sleeve of the linking mechanism is telescoped into a short sleeve, whereby the running board frame is turned upward. Therefore, the running board can be electrically folded. In the case that there is no power supply, a user can directly manually turn the running board upward and fold the running board.
- The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
