Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a stationary exerciser, and more particularly to a stationary exerciser including an improved structure adjustable to different moving stroke for different users or according to the users' requirement.
  • 2. Description of the Prior Art
  • Typical stationary exercisers comprise a pair of foot supports or foot pedals including one end pivotally or rotatably attached or coupled to a base support with a pair of cranks, and including the other end slidably engaged on and supported by a pair of trails or tracks.
  • For example, U.S. Pat. No. 5,352,169 to Eschenbach discloses one of the typical exercise machines also comprising a base support including two rotatable cranks pivotally or rotatably attached or coupled to one end of two elongate pedals by crank pins, and the elongate pedals each include the other end slidably engaged on and supported by a trail or track.
  • However, the trails or tracks are stationarily disposed or supported on the base support and may not be adjust to different angular positions relative to the base support, such that the elongate pedals of the typical exercise machines may not be adjusted to different moving strokes.
  • U.S. Pat. No. 5,772,558 to Rodgers, Jr. discloses another apparatus also comprising two reciprocating members including one end pivotally or rotatably attached or coupled to a base with cranks and a pulley, and including the other end slidably engaged on and supported by rollers or slidably engaged with the lower portion of a frame.
  • However, similarly, the lower portion of the frame is also stationarily disposed or supported on the base and may not be adjusted or moved or tilted to different angular positions relative to the base such that the reciprocating members of the typical stationary exercise apparatus also may not be adjusted to different moving strokes.
  • U.S. Pat. No. 5,846,166 to Kuo discloses a further typical stepping exercise machine also comprising two foot supports including one end pivotally attached or coupled to a pair of handles respectively, and including the other end slidably engaged on and supported by a pair of tracks.
  • However, similarly, the tracks are also stationarily disposed or supported on the base and may not be adjust to different angular positions relative to the base such that the foot supports of the typical stationary exercise apparatus also may not be adjusted to different moving strokes.
  • The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional stationary exercisers or machines.

  • Two foot supports 30 each include a first end or front portion 31 pivotally or rotatably attached or coupled to the eccentric shafts 23 for allowing the front portions 31 of the foot supports 30 to be moved cyclically or circularly in reciprocating action relative to the base 10 by the wheel 21 and/or the eccentric shafts 23, and each include one or more rollers 32 rotatably attached the second end or the rear portion 33 of the respective foot supports 30 for slidably engaging with the rails 15, and each include a foot pedal 34 pivotally attached or supported on the foot support 30 with a pivot pin 35 for allowing the foot pedals 34 or the foot supports 30 to be moved in an elliptical moving path or moving stroke relative to the base 10.
  • Two handles 40 each include a middle portion 41 pivotally or rotatably attached or coupled to the post 11 or the base 10 with a pivot rod 42 (FIG. 2), and each include a hand grip 43 provided on top thereof for being held or grasped by the users, and each include a lower portion 44 pivotally attached or coupled to the foot support 30 with a lever 45, for allowing the handles 40 to be pivotally coupled to the foot support 30 with the lever 45. The above-described structure is typical and will not be described in further details. The levers 45 may include a rear end or a free end 46 bent relative to the lever 45 and acted or operated as a pivot rod 46 which is pivotally or rotatably attached or coupled to the foot pedal 34 and offset from the pivot pin 35 for allowing the foot pedal 34 to be rotated or tilted relative to the foot support 30 with the lever 45 and/or by the handles 40. The levers 45 and the foot pedals 34 may be formed or acted or operated as a coupling means or device for pivotally coupling the handles 40 to the foot supports 30.
  • The stationary exerciser 1 in accordance with the present invention further includes an actuating or adjusting or tilting means or device 5 for tilting or adjusting the rails 15 relative to the base 10 to different angular positions (FIGS. 3-6), and thus for adjusting the foot supports 30 and/or the foot pedals 34 to different moving strokes relative to the base 10. For example, the rails 15 are pivotally or rotatably attached or coupled to the rear portion 16 of the base 10 with an axle 17 for allowing the rails 15 to be pivoted or rotated or adjusted relative to the base 10 to different angular positions and for allowing the rails 15 to be tilted or adjusted relative to the base 10 to different angular positions with or by the tilting device 5.
  • As shown in FIGS. 2 and 5, the rails 15 each may include two rods 18 disposed or arranged parallel to each other and having a middle portion coupled or secured together with a link 19 for forming an elongate and stable structure and for slidably engaging with the rollers 32 that are provided on the rear portion 33 of the foot supports 30. The tilting means or device 5 includes one or more (such as two) arms 50 having one end or front end or first end 51 pivotally or rotatably attached or coupled to the base 10 with a pivot pin 52 and having the other end or rear end or second end 53 (FIGS. 5, 6) movable up and down relative to the base 10. A threaded member or bolt 54 is rotatably attached or secured to the base 10 and coupled to a driving device 55, such as a motor 55 which may rotate the bolt 54 relative to the base 10.
  • A follower 56 is threaded or engaged with the threaded member or bolt 54 and is pivotally coupled to the other or second end 53 of the arm 50 with another pivot pin 57, and the follower 56 is movable or adjustable along the threaded member or bolt 54 when the threaded member or bolt 54 is rotated or driven by the motor 55 such that the arm 50 may be pivoted or rotated or tilted relative to the base 10 by the motor 55 and the bolt 54 and the follower 56. A coupler 60 is straddled or coupled or secured to or between the rails 15 for securing or coupling the rails 15 together, and includes a bracket or seat 61 extended or provided on top thereof for pivotally coupling to the middle portion 58 of the arm 50 with a bar 62 which is pivotally coupled to the middle portion 58 of the arm 50 with a further pivot pin 59. The coupler 60 and/or the seat 61 and/or the bar 62 and/or the arms 50 and/or the follower 56 may be formed or acted or operated as a connecting means or device for pivotally connecting the motor 55 and/or the bolt 54 to the rails 15.
  • In operation, as shown in FIGS. 5 and 6, when the bolt 54 is rotated or driven by the motor 55, the follower 56 may be moved or adjusted along the bolt 54 in order to pivot or rotate or tilt or adjust the arm 50 relative to the base 10 to different angular positions as shown in FIGS. 3 and 4, such that the movement of the rollers 32 of the foot supports 30 along the rails 15 may be adjusted, and such that the foot pedals 34 or the foot supports 30 may be moved or adjusted to different elliptical moving paths or moving strokes relative to the base 10. It is to be noted that the typical stationary exercise devices or machines failed to provide a rail that may be pivoted or rotated or tilted or adjusted relative to the base 10 to different angular positions.
  • Accordingly, the stationary exerciser in accordance with the present invention includes an improved structure adjustable to different moving stroke according to the users' requirement for allowing the users to conduct the stepping or walking exercise with different or suitable 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.
