Description

    FIELD OF THE INVENTION
  • The present invention relates to a treading exerciser, and more particularly, to a treading exerciser with changeable treading traces and a method for controlling the resistance of the treading exerciser.
    • BACKGROUND OF THE INVENTION
  • The conventional treading exerciser is disclosed in FIG. 8 and generally comprises an axle 70 and two first link units 7 are respectively and pivotably connected to the two ends of the axle 70. Each of the first link units 7 has a crank 71, a board 72 and a pivotal rod 73. A pedal 74 is connected on the top of the board 72 so that the user's foot is positioned in the pedal 74 when operating the treading exerciser. Each of the pedals 74 is connected with a second link unit 8 which is pivotably connected to the base of the treading exerciser. When the user treads the pedals 74, the cranks 71 are pivotable about the axle 70 so that the boards 72 are moved up and down. The pedals 74 are driven by the second link units 8 and move the boards 72 back and forth. The pedals 74 move along two respective oval traces.
  • However, the number of the links of the first and second link units 7, 8 is not plenty enough so that the degrees of freedom for the pedals 74 are restricted. In other words, the trace provided by the conventional treading exerciser is fixed and does not meet the practical needs of different users because different users have different distances between the two legs.
  • The present invention intends to provide a treading exerciser which provides changeable treading traces.
    • SUMMARY OF THE INVENTION
  • The present invention relates to a treading exerciser and comprises a base having a front end and a rear end. A first rotary unit and a second rotary unit are respectively connected to the base. The base further has a first pivot and a second pivot connected thereto. The first rotary unit and the second rotary unit are located on the front end of the base.

A second resistance device 33 is connected to the frame 13 so as to provide resistance to the second driving wheel 32.
  • A first link unit 4 comprises multiple links and a first transmission link 42, a first pivotal link 43 and a first connection link 44. The first link unit 4 has a first end thereof connected to the first rotary unit 2 and a second end of the first link unit 4 is connected to the first crank 24. The first crank 24 is connected between the first axle 21 and the first transmission link 42, wherein the first crank 24 is rotatable about the first axle 21, and the first transmission link 42 is pivotably connected to the first crank 24. As shown in FIG. 3, the first connection link 44 has one end fixed to the first connection portion 45 and a pedal 6 is connected adjacent to the first connection portion 45. The first pivotal link 43 is an A-shaped link having a joint end and two distal ends, wherein a first pivotal portion 431 is located at the joint end which is located at the mediate portion of the first pivotal link 43. The first pivotal portion 431 is pivotably connected to the first pivot 131 on the frame 13 of the base 1. The two distal ends of the first pivotal link 43 are respectively and pivotably connected to the first transmission link 42 and the first connection link 44. When the user treads the pedal 6, the first connection link 44 pivots the first pivotal link 43 which pivots about the first pivot 131. The first transmission link 42 pushes the first crank 24 to rotate the first axle 21 so that the first link unit 4 performs the back-and-forth action.
  • A second link unit 5 comprises multiple links and has a first end thereof connected to the second rotary unit 3 and a second end of the second link unit 5 is connected to first connection portion 45 of the first link unit 4. The second link unit 5 comprises a second transmission link 52, a second pivotal link 53, and a second connection link 54. The second crank 34 is connected between the second transmission link 52 and the second axle 31. The second crank 34 is rotatable about the second axle 31. The second pivotal link 53 is an S-shaped link and has a second pivotal portion 531 located at the mediate portion thereof and the second pivotal portion 531 is pivotably connected to a second pivot 132 which is formed on each one of two ends of a U-shaped part which is connected to the base 1. One end of the second pivotal link 53 is pivotably connected to the second transmission link 52 and the other end of the second pivotal link 53 is pivotably connected to the top end of the second connection link 54. The bottom end of the second connection link 54 is pivotably connected to the first connection portion 45 of the first connection link 44 as shown in FIG. 3. When the user treads the pedal 6, the first connection link 44 moves up and down to drive the second connection link 54, and the second pivotal link 53 pivots about the second pivot 132. The second transmission link 52 pushes the second crank 34 to rotate the second axle 31 so that the second link unit 5 performs the up-and-down action.
  • It is noted that the first connection link 44 of the first link unit 4 is pivotably connected to the second connection link 54 of the second link unit 5 by the first connection portion 45, so that the first link unit 4 and the second link unit 5 affect to each other. As shown in FIGS. 4 and 5, when the user treads the pedals 6, the pedals 6 each are moved along the trace T1 as shown in the drawing by the cooperation of the first and second link units 4, 5, and the trace T1 is similar to the trace of the user's feet when jogging. The shown trace T1 is the maximum travel of the pedal 6. Nevertheless, the different users have different paces so that the trace of the pedal 6 changes according to the different paces. As shown in FIG. 6, the trace T2 shows that the pedal 6 is moved down before the maximum distance of the tract T1 is reached, the first connection link 44 is pivoted about the first pivotal link 43, so that the trace T2 differs from the trace T1. In other words, the present invention allows different users to have their own operation modes according to different paces, and the users perform as they are jogging without restriction of the fixed trace of the pedals as described in the conventional treading exerciser.
  • FIG. 7 shows the second embodiment of the present invention, wherein the travel distance of the first link unit 4 is changed by changing the length of any of the links of the first link unit 4. In this embodiment, taken the first transmission link 42 as an example, the first transmission link 42 is composed of an outer tube 42 and an inner tube 42B which is movably inserted into the outer tube 42. A positioning member 42C is connected to the outer tube 42A so as to position the inner tube 42B relative to the outer tube 42A, such that the length of the first transmission link 42 is adjusted and the travel of the first link unit 4 is therefore adjusted as well. Alternatively, by changing any of the pivotal positions of two links of the first link unit 4 can also adjust the travel of the first link unit 4. Taken the first pivotal link 43 as an example, by changing the pivotal positions 43A, 43B between the first transmission link 42 and the first pivotal link 43, the travel of the first link unit 4 is adjusted.
  • Similarly, by changing any of the links of the second link unit 5, the travel distance of the second link unit 5 is changed. In this embodiment, taken the second transmission link 52 as an example, the second transmission link 52 is composed of an outer tube 52 and an inner tube 52B which is movably inserted into the outer tube 52. A positioning member 52C is connected to the outer tube 52A so as to position the inner tube 52B relative to the outer tube 52A, such that the length of the second transmission link 52 is adjusted and the travel of the second link unit 5 is therefore adjusted as well. Alternatively, by changing any of the pivotal positions of two links of the second link unit 5 can also adjust the travel of the second link unit 5. Taken the second pivotal link 53 as an example, by changing the pivotal positions 53A, 53B between the second transmission link 52 and the second pivotal link 53, the travel of the second link unit 5 is adjusted.
  • The present invention further provides a method for controlling resistance of the treading exerciser, wherein the first driving wheel 22 of the first rotary unit 2 is connected to the first transmission wheel 25 by a belt, and the first transmission wheel 25 is connected to the first resistance device 23 by another belt. Similarly, the second driving wheel 32 of the second rotary unit 3 is connected to the second transmission wheel 35 by a belt, and the second transmission wheel 35 is connected to the second resistance device 33 by another belt. By this arrangement, the first resistance device 23 and the second resistance device 33 can be simultaneously or individually adjusted so as to provide different level of resistance to the users. The first resistance device 23 and the second resistance device 33 can be electro-magnetic resistance devices which use electro-magnetic members to generate magnetic force which is transformed into resistance. When the first resistance unit 23 provides the maximum resistance, the first rotary unit 2 cannot rotate due to the maximum resistance, only the second link unit 5 is pivoted about the second pivot 132 to perform up-and-down action, this mode simulates climbing action. On the contrary, when the second resistance unit 33 provides the maximum resistance, the second rotary unit 3 cannot rotate due to the maximum resistance, only the first link unit 4 is pivoted about the first pivot 131 to perform back-and-forth action, this mode simulates skiing or elliptical action. The resistance provided by the first resistance device 23 can be adjusted not to be larger than that by the second resistance device 33, so as to perform different actions to meet different requirements of the users.
  • While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
