Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
Referring to the drawings, and initially to FIGS. 1 and 3-5, a stepping exerciser 1 in accordance with the present invention comprises a base 10 including an upright support 11 extended upwardly from the front portion 12 of the base 10, two posts 13 also extended upwardly from the front portion 12 of the base 10 and disposed or arranged or located on the two side portions of the upright support 11, a stationary frame or support 14 extended upwardly from the middle portion 15 of the base 10 and disposed or arranged or located behind the upright support 11, and one or more, such as two studs 16 extended upwardly from the rear portion 17 of the base 10.
One or more, such as two pairs of foot supports 20, 21 each has a lower portion rotatably or pivotally secured to the base 10 and/or the studs 16 with a pivot axle 22, which is parallel to a longitudinal axis 80 of the base 10 (
As best shown in
As shown in FIGS. 1 and 3-4, two levers 30 each include a lower or front portion 31 rotatably or pivotally secured to the base 10 and/or the posts 13 with a pivot pin 32 for allowing the levers 30 to be pivoted or rotated up and down relative to the base 10, two bars 33 each include one end portion 34 rotatably or pivotally secured to the upright support 11 of the base 10 with a pivot rod 35, and each include a handle 36 extended upwardly therefrom for supporting the upper portion of the user, and each include the other end portion 37 pivotally coupled to a link 38 which is then pivotally coupled to the middle portion 39 of the lever 30 for allowing the levers 30 to be moved or rotated or pivoted up and down relative to the base 10 by the handles 36 and the links 38. It is preferable that a linking means or device 40 is further provided for coupling or linking the levers 30 together.
For example, the linking means or device 40 includes an arm 41 having a center or middle portion rotatably or pivotally coupled or secured to the upright support 11 of the base 10 with a pivot pole 42 (
The levers 30 each include an upper or rear portion 45 rotatably or pivotally coupled or secured to the extensions 28 that are extended from the foot supports 20, 21 or the foot pedals 25 or the frames 27 of the foot pedals 25 with linking members 46 (
A spindle 50 is rotatably supported on the base 10, such as on the stationary support 14 that is extended upwardly from the middle portion 15 of the base 10. A weight or follower 51 and two or more (such as two) pulleys or rotary members 52 are secured on the spindle 50 and rotated in concert with the spindle 50, to increase a moment of inertia of the spindle 50. A flywheel or wheel 53 may further be provided and rotatably supported on the front portion 12 of the base 10 and coupled to the follower 51 with a coupler member 54 (
A brake or retarding device 55, such as an electromagnetic retarding device 55 may further be provided and disposed beside the wheel 53, for applying a resistive force against the wheel 53 and thus the follower 51 and the spindle 50. One or more, such as two belts or resilient or actuating members 56 may further be provided and have one end secured to and engaged onto or around the rotary members 52 respectively for rotating the rotary members 52 and thus the spindle 50 and the follower 51 when the actuating members 56 are unwound from the rotary members 52. The other ends of the resilient or actuating members 56 are then coupled to the upper or rear portions 45 of the levers 30 with fasteners or pegs 47 for allowing the actuating members 56 to be selectively pulled and unwound from the rotary members 52 by the levers 30 respectively. The wheel 53 and the follower 51 may apply a resistive force against the rotational movement of the spindle 50.
It is to be noted that the rotary members 52 are disposed on the spindle 50 with conventional unidirectional bearings (not shown) or the like, and arranged to allow the spindle 50 to be rotated or driven in an active direction by the rotary members 52, and to be rotated freely relative to the rotary members 52 in a reverse direction, and thus to allow the spindle 50 to be rotated or driven in the active direction continuously by the levers 30 and/or the handles 36 alternatively. The retarding device 55 may also be provided to apply the resistive force to resist the movement or the operation of the handles 36 and the rotational movement of the spindle 50 and the follower 51 and the wheel 53. The extensions 28 of the foot supports 20, 21 and the foot pedals 25 may also be pivotally coupled or secured to the other ends of the resilient or actuating members 56 directly with the linking members 46 or indirectly with the levers 30 for allowing the resilient or actuating members 56 to be selectively pulled and unwound from the rotary members 52 by the foot pedal 25 and/or the foot supports 20, 21 respectively when the foot pedals 25 are stepped relative to the base 10 by the users.
Similarly, the spindle 50 may also be rotated or driven continuously by the foot pedals 25, and the rotary members 52 may also be rotated or driven by the handles 36 with the bars 33 and the links 38 and the levers 30 such that the spindle 50 may be continuously rotated or driven by the foot pedals 25 and the handles 22 alternatively, and the retarding device 55 and the resilient or actuating members 56 may also apply a resistive force against the rotational movement of the spindle 50 and thus the swinging movement of the handles 36, and thus the stepping operation of the foot pedals 25 and the foot supports 20 or 21 respectively, and thus for allowing the users to exercise or to train the upper muscle groups and/or the lower muscle groups of the users.
The extensions 28 extended from the foot supports 20 or 21 and the linking members 46 and/or the levers 30 and the actuating members 56 may thus be used or formed or acted as a coupling means or device for coupling the foot pedals 25 or the foot supports 20 or 21 to the spindle 50, to allow the spindle 50 to be rotated or driven continuously by the foot pedals 25 or the foot supports 20 or 21. In addition, the actuating members 56 and the levers 30 and the links 38 and the bars 33 and the handles 36 may thus be used or formed or acted as a connecting means or device for connecting the handles 36 to the spindle 50, and thus to allow the spindle 50 to be rotated or driven continuously by the handles 36. The typical stepping exercisers may not be used to rotate or to drive a spindle continuously by the handles 36 and the foot pedals 25 or the foot supports 20 or 21.
Accordingly, the stepping exerciser in accordance with the present invention includes a weight or flywheel rotatable or drivable or actuatable by either or both the handles and the foot supports of the stepping exerciser, to provide a resistive force against the stepping exerciser, and includes a handle selectively actuatable or operatable by the users, and includes a spindle to be rotated or driven by both the foot pedals and the handles.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
