Description
- 1. Field of the Invention
- This invention relates to an exerciser, more particularly to an exerciser with an adjustable resistance providing member.
- 2. Description of the Related Art
- Conventional exercisers,,such as weight stack exercisers, are too heavy for transport. Moreover, many conventional stretching exercisers can only provide fitness on one part of the body, such as the arm or leg.
- Therefore, the object of the present invention is to provide an exerciser that is relatively light and simple and that can provide fitness on many parts of the body.
- According to the present invention, there is provided an exerciser that comprises: a supporting frame having a base with opposite front and rear ends, and an upright post that extends upright from the front end and that has a top end; a lever having a pivot end that is pivoted to the top end of the upright post so as to permit rotation of the lever relative to the supporting frame, and a free end that is opposite to the pivot end, the lever extending from the upright post in a first transverse direction relative to the upright post; a resistance providing member interconnecting the supporting frame and the lever so as to provide resistance to rotation of the lever; a pulley mechanism including an upper pulley unit mounted rotatably on the free end of the lever and including at least an upper pulley, and a lower pulley unit mounted rotatably on the supporting frame, disposed below and aligned with the upper pulley unit, and including at least a lower pulley; and a string having a free end, and a fixed end that is fixed to the supporting frame. The string extends upwardly from the fixed end to the upper pulley, passes over the upper pulley, extends downwardly from the upper pulley to the lower pulley, and then passes under the lower pulley so as to permit rotation of the lever when the free end of the string is pulled away from the pulley mechanism.

- FIGS.1 to 4 illustrate the preferred embodiment of an exerciser according to the present invention. The exerciser includes: a supporting frame 10 having a base 11 with opposite front and rear ends 111, 112, and an upright frame part 12 that includes two parallel upright posts 121 extending upright from the front end 111 of the base 11 and respectively having top ends; a lever 19 having a pivot end 190 that is pivoted to the top end of one of the upright posts 121 so as to permit rotation of the lever 19 relative to the supporting frame 10, and a free end 191 that is opposite to the pivot end 190, the lever 19 extending from said one of the upright posts 121 in a first transverse direction relative to the upright posts 121 toward the other of the upright posts 121; a resistance providing member 20 disposed between the upright posts 121 and interconnecting the front end 111 of the base 11 of the supporting frame 10 and the lever 19 so as to provide resistance to rotation of the lever 19; a pulley mechanism including an upper pulley unit 3 mounted rotatably on the free end 191 of the lever 19 and including a pair of first and second upper pulleys 31, 32, a lower pulley unit 4 mounted rotatably on the front end 111 of the base 11 of the supporting frame 10, disposed below and aligned with the upper pulley unit 3, and including a pair of first and second lower pulleys 41, 42, a side pulley 5 mounted rotatably on the front end 111 of the base 11 and disposed adjacent to and aligned with the second lower pulley 42 in the first transverse direction, and a front pulley 6 mounted rotatably on the rear end 112 of the base 11 and aligned with the side pulley 5 in a second transverse direction that is transverse to the first transverse direction and the upright posts 121; and a string 7 having a free end 71, and a fixed end 72 that is fixed to the supporting frame 10. The
string 7 extends upwardly from the fixedend 72 to the firstupper pulley 31, passes over the firstupper pulley 31, extends downwardly from the firstupper pulley 31 to the firstlower pulley 41, passes under the firstlower pulley 41, extends upwardly from the firstlower pulley 41 to the secondupper pulley 32, passes over the secondupper pulley 32, extends downwardly from the secondupper pulley 32 to the secondlower pulley 42, passes under the secondlower pulley 42, extends laterally from the secondlower pulley 42 to theside pulley 5 in the first transverse direction, passes by theside pulley 5, extends laterally from theside pulley 5 to thefront pulley 6 in the second transverse direction, and then passes under thefront pulley 6. Accordingly, thelever 19 is rotated upon pulling thefree end 71 of thestring 7 away from thefront pulley 6 of the pulley mechanism. Astopper 22 is fixed to thefree end 71 of thestring 7. A pair of foot steps 18 are mounted on thefront end 112 of thebase 11. - In this preferred embodiment, the
resistance providing member 20 is a hydraulically operated device, and includes ahydraulic cylinder 202 that is pivoted to thefront end 111 of thebase 11, and apiston 201 that telescopically extends into thehydraulic cylinder 202 and that has apivot end 2011 connected to thelever 19. Alternatively, theresistance providing member 20 can be a spring for providing resistance to rotation of thelever 19. - The
lever 19 is formed with a plurality ofpositioning holes 193 that are aligned along the length of thelever 19. Theresistance providing member 20 further includes acoupler 2012 and a pin 2013 (see FIG. 4). Thecoupler 2012 is in the form of a U-shaped plate that has two opposingarms 2014 which are disposed at two opposite sides of thelever 19. Thepivot end 2011 of thepiston 201 is pivoted to the opposingarms 2014. Thepin 2013 extends through the opposingarms 2014 and a selected one of the positioning holes 193 in thelever 19 so as to position thepivot end 2011 of thepiston 201 at the selected one of the positioning holes 193 and so as to adjust the resistance provided by theresistance providing member 20 to rotation of thelever 19. The resistance is largest for thepositioning hole 193 closest to the free end 191 of thelever 19. - FIGS.5 to 7 illustrate operation states of the exerciser of this invention during exercising with both hands of the user. The
free end 71 of thestring 7 is connected to achain 23 through thestopper 22. A grippingmember 232, which is in the form of a handle, is provided on thechain 23. In FIGS. 5 and 6, thestring 7 is pulled upwardly from a lower position shown in FIG. 7 by the user to rotate thelever 19 downwardly, which, in turn, results in movement of thepiston 201 into thehydraulic cylinder 202. - FIG. 8 illustrates an operation state of the exerciser of this invention during exercising with one leg of the user. The
handle 232 shown in FIG. 5 is replaced by abelt 242 that can be sleeved on the leg of the user. - FIGS. 9 and 10 illustrate operation states of the exerciser of this invention during exercising of the waist of the user. The
handle 232 shown in FIG. 5 is replaced by astrap 25 that can be sleeved on the waist of the user. - With the invention thus explained, it is apparent that various modifications and variations can be made without departing from the spirit of the present invention. It is therefore intended that the invention be limited only as recited in the appended claims.
