1. Field of the Invention
The present invention relates to a stepping exerciser, and more particularly to a stepping exerciser having a weight or flywheel rotatable or drivable by the stepping exerciser, to provide a resistive force against the stepping exerciser.
2. Description of the Prior Art
Typical stepping exercisers comprise a pair of foot supports or foot pedals pivotally or rotatably attached on a base, and movable up and down, for conducting up and down stepping exercises. Normally, the foot supports or foot pedals may be moved up and down only, and may not be moved laterally and outwardly relative to the users.
U.S. Pat. No. 5,518,470 to Piaget et al., and U.S. Pat. No. 6,595,899 to Liang disclose two further typical stepping exercisers each comprising a pair of foot supports or foot pedals pivotally or rotatably attached on a base, and movable laterally and outwardly relative to the base and the users, for conducting other types of exercises, such as mountain climbing exercises, snow skiing exercises, etc.
However, the foot supports or foot pedals of the typical stepping exercisers may not be used to rotate or to drive a weight or a flywheel. In addition, the typical stepping exercisers have no handles to be moved or operated by the users to train the upper muscle groups of the users.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional stepping exercisers.
The primary objective of the present invention is to provide a stepping exerciser including a weight or flywheel rotatable or drivable by the stepping exerciser, to provide a resistive force against the stepping exerciser.
The other objective of the present invention is to provide a stepping exerciser including a handle selectively actuatable or operatable by the users.
The further objective of the present invention is to provide a stepping exerciser including a spindle to be rotated or driven by both the foot pedals and the handles.
In accordance with one aspect of the invention, there is provided a stepping exerciser comprising a base, a spindle rotatably supported on the base, a pair of foot pedals rotatably supported on the base, and arranged to be moved up and down and stepped by a user, a coupling device for coupling the foot pedals to the spindle, to drive and to rotate the spindle, a pair of handles rotatably supported on the base, and arranged to be rotated by the user, and a connecting device for connecting the handles to the spindle, to drive and to rotate the spindle, and thus to allow the spindle to be rotated continuously by the handles and the foot pedals alternatively.
The coupling device includes two arms extended from the spindle, and pivotally coupled to the foot pedals with links. The foot pedals each includes an extension extended therefrom and pivotally coupled to the links, to allow the spindle to be rotated and driven continuously by the foot pedals.
The connecting device includes two rotary members attached onto the spindle, and two cables coupled between the rotary members and the handles. The base includes at least two pulleys rotatably disposed thereon, for engaging with the cables respectively, to allow the spindle to be rotated and driven continuously by the handles.
The base includes two posts extended upwardly therefrom to support the pulleys thereon respectively, and each of the posts includes a bracket disposed thereon, to rotatably support the pulleys thereon respectively. The base includes a hand grip secured between the posts, for supporting an upper portion of the user.
The rotary members each includes a spring member engaged thereon, and coupled between the rotary members and the base, to apply a resistive force against a rotational movement of the rotary members and the spindle. The spindle includes a follower secured thereon and rotated in concert with the spindle to increase a moment of inertia of the spindle.
The base includes a wheel rotatably disposed thereon and coupled to the follower, to apply a resistive force against the follower and the spindle. The base includes a retarding device provided thereon and disposed for applying a resistive force against the wheel.
The base includes two pairs of levers rotatably secured thereon, and pivotally coupled to the foot pedals, to form a parallelogrammic structure to stably support the foot pedal. The levers each includes an upper portion having a tube laterally extended therefrom, for rotatably securing the foot pedals thereto with pivot rods. The foot pedal each includes a frame attached to the bottom portion thereof, for rotatably securing to the tubes or the levers with the pivot rods respectively.
The base includes two studs extended upwardly therefrom, the levers are rotatably secured to the base and the studs with pivot axles, the pivot axles are parallel to a longitudinal axis of the base, to allow the levers to be moved sidewise and outwardly relative to the base. The tubes of the foot pedals are also preferably parallel to the longitudinal axis of the base.
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
Each of the handles 22 includes a coupler 24 disposed or secured thereon, to attach or to secure one end of a rope or cable 25 which may be engaged over the pulley 21, for allowing the cables 25 to be smoothly pulled by the handles 22 when the handles 22 are rotated relative to the bracket 20 and the posts 11 respectively. The base 1 may further include one or more wheels or pulleys 26 rotatably disposed or attached thereon, for engaging with the cables 25, or for allowing the cables 25 to be engaged onto or around the pulleys 26 respectively. The base 1 further includes two studs 13 extended upwardly from the rear portion 10 thereof.
One or more, such as two pairs of levers 30, 31 each has a lower portion rotatably or pivotally secured to the base 1 and/or the studs 13 with a pivot axle 32, which is parallel to a longitudinal axis A of the base 1 (
For example, the foot pedal 35 each includes a frame 37 attached to bottom thereof, for rotatably or pivotally securing to the tubes 34 or the levers 30, 31 with the pivot rods 36, for allowing the foot pedal 35 also to be moved or rotated laterally or sidewise and outwardly relative to the base 1, best shown in
A spindle 40 is rotatably supported on the base 1 with one or more columns 14 that are extended upwardly from the base 1. A weight or follower 41 and two or more, such as four rotary members 42 are secured on the spindle 40 and rotated in concert with the spindle 40, to increase a moment of inertia of the spindle 40. A flywheel or wheel 43 may further be provided and rotatably supported on the front portion 15 of the base 1 and coupled to the follower 41 with a coupler member 44 (
A brake or retarding device 45, such as an electromagnetic retarding device 45 may further be provided and disposed beside the wheel 43, for applying a resistive force against the wheel 43 and thus the follower 41 and the spindle 40. One or more, such as four resilient or spring members 46 may further be provided and have one end secured to and engaged onto or around the rotary members 42 respectively, and the other end engaged or secured to such as the base 1, to further apply a resistive force against the rotational movement of the rotary members 42 and thus the spindle 40 and the follower 41.
The cables 25 are engaged onto or around the pulleys 26 respectively, and are then engaged around two of the rotary members 42, for allowing the rotary members 42 and thus the spindle 40 and the follower 41 to be rotated or driven by the handles 22 when the handles 22 are rotated relative to the bracket 20 and the posts 11 by the users, such that the handles 22 may be operated against the retarding device 45 and the resilient or spring members 46, in order to exercise or to train the upper muscle groups of the users.
It is to be noted that the rotary members 42 are disposed on the spindle 40 with conventional unidirectional bearings (not shown) or the like, and arranged to allow the spindle 40 to be rotated or driven in an active direction by the rotary members 42, and to be rotated freely relative to the rotary members 42 in a reverse direction, and thus to allow the spindle 40 to be rotated or driven in the active direction continuously by the handles 22 alternatively. The retarding device 45 may also be provided to apply the resistive force against the handles 22 via the spindle 40 and the follower 41 and the wheel 43.
The spindle 40 further includes two arms 47 extended therefrom or coupled thereto, and pivotally coupled to the extensions 38 that are extended from the levers 30 or 31 respectively, with such as links 48, best shown in
In operation, the spindle 40 may be rotated or driven continuously by the foot pedals 35, and the rotary members 42 may also be rotated or driven by the handles 22 via the cables 25, such that the spindle 40 may be continuously rotated or driven by the foot pedals 35 and the handles 22 alternatively. The follower 41 and the wheel 43 may apply a resistive force against the spindle 40, and the resilient or spring members 46 may also be provided to apply a resistive force against the spindle 40.
The arms 47 extended from the spindle 40 and the extensions 38 extended from the levers 30 or 31 and the links 48 may thus be used or formed as a coupling means or device for coupling the foot pedals 35 to the spindle 40, to allow the spindle 40 to be rotated or driven continuously by the foot pedals 35. In addition, the rotary members 42 attached onto the spindle 40 and the cables 25 may thus be used or formed as a connecting means or device for connecting the handles 22 to the spindle 40, and thus to allow the spindle 40 to be rotated or driven continuously by the handles 22.
As shown in
Accordingly, the stepping exerciser in accordance with the present invention includes a weight or flywheel rotatable or drivable by 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.
