Abstract
An adjustable rock arm of a climbing treadmill, including a swinging unit including a rock arm and an oil cylinder. A rear end of the rock arm via a shaft is pivotally connected with the upright support. The oil cylinder is disposed under the rock arm. By means of a fixing bracket, an upper end of the oil cylinder is connected with the rock arm. A lower end of the oil cylinder via a fixing member is fixed on an upright support. The oil cylinder is restorable and adjustable in tension and pulling force so as to provide different resistance against the rock arm for exercising a user's arms to different extent.
Description
- The present invention is related to a climbing treadmill, and more particularly to an adjustable rock arm of a climbing treadmill. The slope of the climbing treadmill is adjustable and the resistance against the rock arm is also adjustable in accordance with the slope and the natural swinging arch of a user's arms for exercising the arms to different extent.

FIG. 6 shows a conventional treadmill including amainframe 61, aframe body 62, afront support 63 and arear support 64. An electronic control instrument is disposed on themainframe 61. Twohandles bars 66 are mounted on two sides of themainframe 61. Theframe body 62 is looped with a running belt which revolves around theframe body 62. In addition, tworock arm assemblies 67 are respectively pivotally mounted on twopivot shafts 68 of front side of themainframe 61 near upper end thereof. The tworock arm assemblies 67 have the same structure. Eachrock arm assembly 67 includes arotary bar 69 and aholding rock arm 70 having a holding end. One end of therotary bar 69 is pivotally connected with a corresponding pivot shaft of themainframe 61, while the other end of therotary bar 69 is pivotally connected with one end of the holding rock arm 60. A cord-likeresilient member 71 is additionally disposed between therotary bar 69 and the bottom of theframe body 62 for providing a certain resistance against theholding rock arm 70. According to the above structure, a user cannot easily operate the treadmill and it is inconvenient to adjust the resistance. Moreover, the cord-likeresilient member 71 tends to be clogged by an alien article. This will lead to malfunction of the treadmill. Furthermore, the structure of the treadmill is complicated and hard to manufacture or assemble. - It is therefore a primary object of the present invention to provide an adjustable rock arm of a climbing treadmill. The slope of the climbing treadmill is adjustable and the resistance against the rock arm is also adjustable in accordance with the slope and the natural swinging arch of a user's arms for exercising the arms to different extent.
- According to the above object, the adjustable rock arm of the climbing treadmill of the present invention includes a swinging unit including a rock arm and an oil cylinder. A rear end of the rock arm via a shaft is pivotally connected with the upright support. The oil cylinder is disposed under the rock arm. By means of a fixing jacket, an upper end of the oil cylinder is connected with the rock arm. A lower end of the oil cylinder via a fixing member is fixed on an upright support.
- The present invention can be best understood through the following description and accompanying drawings wherein:
-
FIG. 1 is a perspective assembled view of the present invention; -
FIG. 2 is a side view of the present invention; -
FIG. 3 is a sectional view showing the operation of the oil cylinder of the present invention in one state; -
FIG. 4 is a sectional view showing the operation of the oil cylinder of the present invention in another state; -
FIG. 5 is a side view showing the operation of the present invention; and -
FIG. 6 is a side view of a conventional treadmill. - Please refer to FIGS. 1 to 5. The adjustable rock arm of the climbing treadmill of the present invention includes a fixed frame body 1 and two
upright supports 2 respectively upward extending from two sides of the fixed frame body 1. Twohandle bars 3 and an electronic instrument 4 are mounted on theupright supports 2. A swingingunit 5 is disposed on eachupright support 2. A supportingframe 11 is mounted on the fixed frame body 1 and a swingingframe 12 is connected with the supportingframe 11. An electriccirculating belt assembly 13 is mounted on the swingingframe 12. An electrictelescopic actuator 14 is disposed under the swingingframe 12 for adjusting the elevation and slope of the swingingframe 12 in accordance with different trainings. - Each swinging
unit 5 includes arock arm 51 and anoil cylinder 52. A rear end of therock arm 51 via ashaft 53 is pivotally connected with a lateral side of theupright support 2. Theoil cylinder 52 is an exercise-used one and disposed under therock arm 51. By means of afixing bracket 54, the upper end of theoil cylinder 52 is connected with therock arm 51. The lower end of theoil cylinder 52 via afixing member 55 is fixed on theupright support 2. Referring toFIG. 3 , apiston rod 521 and apiston 522 are disposed in theoil cylinder 52. When restoringspring 521 is pulled and extended, thepiston 522 is driven to move upward. At this time, a part of the oil will flow out of theinner oil tube 525 and a part of the oil will flow through theoil hole 526 of thepiston 522 and thehole 527 of the bottom of theinner oil tube 525 out of theinner oil tube 525. Accordingly, the oil can be released in two directions so as to save the strength of an operator. - Referring to
FIG. 4 , after restoringspring 521 is released from the pulling force, restoringspring 521 is retracted. At this time, therestoring spring 53 exerts a reverse force onto restoringspring 521 so that restoringspring 521 tends to restore to its initial position. The pressure in theinner oil tube 525 is reduced so that a part of the oil outside theinner oil tube 525 is sucked back through theoil outlet 528, while a part of the oil will flow through theoil hole 526 of thepiston 522 back into theinner oil tube 525. Accordingly, restoringspring 521 can automatically retrieve to its initial position without manually pressingback restoring spring 521. The operator can temporarily rest at this buffering moment so as to avoid injury during exercise. By means of a regulatingtuner 54 of theoil cylinder 52, the amount of the oil can be controlled to set different amount of tension and pulling force for exercising the operator's arms. - The operator can stand on the electric circulating
belt assembly 13 with both hands holding therock arms 51. The operator can tread the circulatingbelt assembly 13 and cooperatively swing therock arms 51 with both hands. By means of theoil cylinders 52, therock arms 51 can automatically restore. In addition, the tension and pulling force can be adjusted for training the operator's arms. The elevation of the circulatingbelt assembly 13 can be adjusted to form different slopes for different trainings. - 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.
