Abstract
An Exerciser including a main body and at least one cord reel rotatably disposed on the main body. A pull cord is wound around the cord reel. The cord reel is equipped with a restoring mechanism for driving the cord reel to wind back the pulled out pull cord. The cord reel is connected with a shaft which is further connected with a one-way mechanism. Only when the pull cord is pulled to rotate the cord reel, the one-way mechanism one-way drives a resistance wheel which creates a resistance for achieving exercising effect. The main body is equipped with a friction adjustment device for adjusting the resistance against the resistance wheel so as to vary the extent to which a user is exercised.
Description
- A present invention is related to an exerciser, and more particularly to a pull cord exerciser in which a cord reel is equipped with a restoring mechanism for driving the cord reel to wind back the pulled out pull cord. The cord reel is connected with a shaft which is further connected with a one-way mechanism. Only when the pull cord is pulled to rotate the cord reel, the one-way mechanism one-way drives a resistance mechanism which creates a resistance for achieving exercising effect.
- A conventional pull cord exerciser is generally mounted on a large-size combinational exerciser. The pull cord is wound through a pulley assembly to drive a weight block. A gravitational force of the weight block serves as a resistance against the pulling force so as to achieve an exercising effect.
- After a user pulls the pull cord to a limit position, the user must gradually reduce the pulling force, permitting the weight block to descend. Accordingly, in the backward travel of the pull cord, the user still needs to exert a considerable force against the gravitational force of the weight block. Otherwise, the weight block will abruptly acceleratively drop down to injure the user, especially in the case that the user is a beginner.
- In some simple-type pull cord exercisers, the pull cord is made of elastic material. The pull cord's own resilient force serves as the resistance against the pulling force for achieving exercising effect.
- The stronger the resilient force of the pull cord is, the better the exercising effect is. However, the strong elastic pull cord will exert a great backward force onto the user. Therefore, after pulling and tensioning the pull cord, the user needs to exert a considerably great force to resist against the backward resilient force of the pull cord. Otherwise, the user may get hurt.
- It is therefore a primary object of the present invention to provide an exerciser including a main body and at least one cord reel rotatably disposed on the main body. A pull cord is wound around the cord reel. The cord reel is connected with a shaft which is further connected with a one-way mechanism. The one-way mechanism is connected with a resistance mechanism. Only when the pull cord is pulled by a user to rotate the cord reel, the one-way mechanism one-way drives the resistance mechanism which creates a resistance for achieving exercising effect. The cord reel is equipped with a restoring mechanism for driving the cord reel to wind back the pulled out pull cord. Therefore, the user is protected from getting hurt during the backward travel of the pull cord.
- It is a further object of the present invention to provide the above exerciser in which the main body is equipped with a friction adjustment device for adjusting the resistance against the resistance wheel. By means of turning an adjustment bolt, the frictional force exerted by a frictional belt against the frictional wheel can be changed so as to vary the extent to which a user is exercised.
- 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 sectional view taken along line II-II of FIG. 1;
- FIG. 3 shows the arrangement of the coiled spring in the cord reel of the present invention;

- FIG. 9 shows the use of the present invention in another state.
- Please refer to FIGS.1 to 6. The exerciser of the present invention includes a
main body 1 and twostep boards 11 laterally extending from two sides of themain body 1. One end of eachstep board 11 distal from themain body 1 has agrip section 12. Twocord reels 13 are rotatably disposed on themain body 1 via twoshafts 16. Apull cord 14 is wound around eachcord reel 13. Thecord reel 13 is recessed and formed with areceiving space 131 in which acoiled spring 15 is disposed. The coiledspring 15 has anouter end 151 and aninner end 152. Theouter end 151 is hooked with thecord reel 13, while theinner end 152 is hooked on apin member 17 passing through themain body 1 near theshaft 16. Theshaft 16 is connected with a one-way mechanism 18. In this embodiment, the one-way mechanism 18 is a one-way bearing 18. When thepull cord 14 drives thecord reel 13 to rotate, the one-way bearing 18 one-way drives a resistance mechanism. In this embodiment, the resistance mechanism is africtional wheel 19. - The
main body 1 is equipped with afriction adjustment device 2 corresponding to thefrictional wheel 19. Thefriction adjustment device 2 has africtional belt 21 wound around the twofrictional wheels 19. Two ends of thefrictional belt 21 are fixed on amovable seat 22 fitted on aslide block 23. Theslide block 23 has twoprojecting sections 231 inserted in aslide slot 101 of themain body 1. Anadjustment bolt 24 is screwed in theslide block 23. Aspring 25 is disposed between theslide block 23 and themovable seat 22. By means of turning theadjustment bolt 24, theslide block 23 is driven and moved to push thespring 25 against themovable seat 22 so as to change the driving force exerted by themovable seat 22 onto thefrictional belt 21. Accordingly, the frictional force exerted by thefrictional belt 21 against thefrictional wheels 19 is changed so as to change the frictional resistance against thefrictional wheels 19 is changeable. - The
main body 1 is equipped with aguide mechanism 3 corresponding to eachpull cord 14. Theguide mechanism 3 includes arotary seat 31 pivotally disposed on themain body 1 and freely rotatable. Therotary seat 31 has an axial throughhole 32 through which thepull cord 14 is passed. One end of thepull cord 14 extending out of therotary seat 31 is connected with ahandle 141. An end of the throughhole 32 from which thepull cord 14 extending out is defined as anoutlet end 321. Apulley 33 is rotatably disposed on therotary seat 31 at theoutlet end 321 of the throughhole 32. Apin member 34 is passed through therotary seat 31 near thepulley 33. A gap is defined between thepulley 33 and thepin member 34, just permitting thepull cord 14 to pass therethrough. Accordingly, thepull cord 14 is restricted by thepin member 34 and wound on thepulley 33. When thepull cord 14 is pulled out or wound in, therotary seat 31 is rotatable along with thepull cord 14. Moreover, thepulley 33 serves to guide thepull cord 14 to reduce the resistance against the travel of thepull cord 14. - Referring to FIG. 7, in use, a user can step on the
step boards 11 and hold thehandles 141 of thepull cords 14 with both hands. When the user pulls thepull cords 14 to drive thecord reels 13 to rotate, thecoiled springs 15 are wound tight. At this time, the one-way bearing 18 on theshaft 16 will drive thefrictional wheel 19 to rotate. Thefrictional belt 21 abuts against thefrictional wheel 19 so that when the user pulls thepull cord 14, it is necessary for the user to exert a force against the frictional force between thefrictional wheel 19 and thefrictional belt 21. Accordingly, an exercising effect is achieved. When the user no more exerts the pulling force, the restoring force of the coiledspring 15 will drive thecord reel 13 to wind thepull cord 14. Thecoiled spring 15 is designed simply for pulling back thepull cord 14 so that thecoiled spring 15 can have lower torque so as to avoid load on the user. When thecord reel 13 winds thepull cord 14, theshaft 16 is idle-off the one-way bearing 18 without driving thefrictional wheel 19. Therefore, when thepull cord 14 is pulled back, the user only needs to slightly exert a force against the restoring force of the coiledspring 15. Therefore, the user is protected from getting hurt during the backward travel of the pull cord. - As necessary, the user can turn the
adjustment bolt 14 to adjust the position of theslide block 23 so as to change the pushing force exerted by theslide block 23 onto thespring 25. Accordingly, the pushing force exerted by thespring 25 onto themovable seat 22 is changeable. The greater the pushing force is, the tighter themovable seat 22 pulls thefrictional belt 21. Therefore, thefrictional belt 21 will abut against thefrictional wheel 19 by greater force. As a result, a greater resistance is created to exercise the user to a greater extent. When it is desired to minify the frictional resistance, theadjustment bolt 14 is turned in reverse direction. - The gap defined between the
pulley 33 and thepin member 34, just permits thepull cord 14 to pass therethrough, whereby thepull cord 14 is restricted by thepin member 34 and kept wound on thepulley 33. Therefore, when thepull cord 14 is pulled out or wound in, therotary seat 31 is rotatable along with thepull cord 14. Moreover, thepulley 33 serves to rotationally guide thepull cord 14 so that the resistance against the movement of thepull cord 14 is reduced. Therefore, thepull cord 14 can, be pulled out by the user in any direction. - Alternatively, a user can hold the
grip sections 12 of themain body 1 with both hands and step on thehandles 141 of thepull cords 14 as shown in FIG. 9. Under such circumstance, the user can use his/her both feet to pull thepull cords 14 for exercising the feet. - In conclusion, when a user pulls the
pull cords 14 to drive and rotate thecord reels 13, the one-way bearings 18 drive thefrictional wheels 19 to achieve an exercising effect. Thecoiled spring 15 of thecord reel 13 serves to drive thecord reel 13 to wind back thepull cord 14 and the user is protected from getting hurt in backward travel of thepull cord 14. Furthermore, by means of turning theadjustment bolt 24 of thefriction adjustment device 2, the user can change the frictional force between thefrictional belt 21 and thefrictional wheel 19 so as to change the exercising extent. - 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.
