It is to be noted that the pivotal coupling of the connectingmember 32 between thehandle 20 and thefoot support 30 may maintain the relative coupling of thecoupling device 40 between thearm 24 of thehandle 20 and thefoot support 30 and may maintain thearm 24 of thehandle 20 at the forwardly or outwardly extended position relative to thebase 10, to allow thearm 24 of thehandle 20 and thefront portion 31 of thefoot support 30 to be moved forwardly and rearwardly and upwardly and downwardly in the curved moving stroke relative to theupright support 11 of thebase 10, and to prevent thearm 24 of thehandle 20 from being dependent downwardly relative to theupright support 11 of thebase 10. It is preferable that the connectingmember 32 is disposed beside and parallel to thefoot support 30. However, it is to be noted that thefoot support 30 may further include an opening (not shown) formed or provided in thefront portion 31 thereof for slidably receiving theother end 34 of the connectingmember 32. - A pair of or two
cranks 50 are rotatably attached or secured to anupright post 13 that is extended upwardly from therear portion 14 of thebase 10 with anaxle 15, and thecranks 50 each include apivot rod 51 provided or attached thereto or extended outwardly therefrom and spaced away from or distal to theaxle 15 for pivotally coupling to therear portion 36 of thefoot support 30 withlinks 52 and for allowing therear portions 36 of the foot supports 30 to be rotated and swung relative to theupright post 13 of thebase 10 in a cycling and/or reciprocating action, and thus for allowing the foot supports 30 to be moved relative to thebase 10 in an elliptical moving stroke. The foot supports 30 each include afoot pedal 37 provided thereon for supporting the feet of the users and for allowing thefoot pedal 37 to be stepped or moved or operated in the elliptical moving stroke by the users. The one ends 33 of the connectingmembers 32 may be pivotally coupled to thefoot pedals 37 which may be pivotally coupled to the foot supports 30 withpivot poles 38 that are provided on themiddle portions 39 of the foot supports 30. - A rotary member or pulley or
wheel 60 is attached or secured to theaxle 15 and moved or rotated in concert with theaxle 15 and thecranks 50, another wheel or pulley orrotary member 61 is rotatably attached to theupright post 13 or the middle orrear portion 14 of thebase 10 with ashaft 62, and therotary member 61 or theshaft 62 is coupled to thewheel 60 with acoupling device 63 which may be selected from such as a sprocket-and-chain coupling device or a gearing coupling device (not shown), or abelt 63 for allowing therotary member 61 to be rotated or driven by thewheel 60 and thecranks 50. Therotary member 61, thewheel 60 and theshaft 62 are coupled together to form a resistive means or device for applying a resistive force or for resisting the rotational movement of thewheel 60 and theaxle 15 and thecranks 50. However, the other resistive device, such as the hydraulic or pneumatic resistive devices (not shown), or the magnetic retarding devices (not shown) may also be used to apply the resistive force against thewheel 60 and theaxle 15 and thecranks 50. - The
cranks 50 each include twocrank segments 53 and arod 54 secured between thecrank segments 53 for allowing thecrank segments 53 to be arranged parallel to each other but offset from each other. Two connecting means ordevices 70 may further be provided and pivotally coupled between the foot supports 30 and thecranks 50 for determining the movement of the foot supports 30 and/or for adjusting the foot supports 30 to different moving strokes. The connecting means ordevices 70 each include alever 71 having anupper end 72 pivotally coupled to theupright post 13 or therear portion 14 of thebase 10 with apivot shaft 16, and having alower end 73 pivotally coupled to the foot supports 30, such as themiddle portion 39 of the foot supports 30 withbeams 74, and having amiddle portion 75 pivotally coupled to thecranks 50, such as therods 54 of thecranks 50 withpivot bars 55. - For example, the
levers 71 each include one ormore orifices 76 formed therein, such as formed in themiddle portion 75 thereof and communicating with each other, and afastener 77 may force thepivot bars 55 to selectively engage with either of theorifices 76 of thelevers 71 and to adjustably secure thepivot bars 55 to thelevers 71 at the selected or different positions, and thus for adjustably securing thelevers 71 to thecranks 50, and thus for indirectly and adjustably securing thefoot support 30 to thecranks 50. It is to be noted that thepivot bars 55 may adjustably secure thelevers 71 to thecranks 50 such that the movement of thefoot support 30 relative to theupright post 13 of thebase 10 may be suitably adjusted and such that the moving stroke of thefoot support 30 relative to thebase 10 may also be suitably adjusted. - It is to be noted that the example of the coupling of the
front portions 31 of the foot supports 30 to thebase 10 has been disclosed and filed in a co-pending patent application, however, thefront portions 31 of thefoot supports 30 may also be coupled to the front portion of thebase 10 with curved tracks (not shown), downwardly dependent or swing arms (not shown), or rotary members or pulleys or wheels or rollers (not shown) or other coupling devices (not shown) which may pivotally couple and support the front portions of the foot supports 30 to the front portion of thebase 10 or may allow thefront portions 31 of the foot supports 30 to be moved in a cycling or forward and rearward reciprocating action relative to the front portion of thebase 10. - The present invention is to provide a pivotal coupling of the connecting means or
devices 70 between the foot supports 30 and thecranks 50 to maintain the relative coupling of the connecting means ordevices 70 and thelink 52 between thecranks 50 and thefoot support 30, for determining the movement of the foot supports 30 and/or for allowing therear portions 36 of the foot supports 30 to be moved relative to thebase 10 in an elliptical moving path (FIGS. 6-8 ), and/or for adjusting the foot supports 30 to different moving strokes. The typical stationary exercisers failed to provide the foot supports that include a rear portion moveable relative to the base 10 in an elliptical moving path, and also failed to provide the foot supports that may be adjusted to different moving strokes relative to thebase 10. - Accordingly, the stationary exerciser in accordance with the present invention includes an improved structure for allowing the front portion of the stationary exerciser to be in different moving strokes, and for allowing the rear portion of the stationary exerciser to be adjusted to different moving strokes.
- 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.
