[0001] 1. Field of the Invention
[0002] The present invention relates to an exerciser, and more particularly to an exerciser having a tiltable seat support and having an adjustable resistive device.
[0003] 2. Description of the Prior Art
[0004] Various kinds of typical exercisers have been developed for simulating cycle exercising, and include a resistive device for applying a resistive force against the foot pedals or the like. Some of the exercisers may include a resistive device that may be changed to different resistive forces. However, a complicated configuration or a number of parts or elements are required for applying the resistive force to the foot pedals or the like and for adjusting to different resistive forces, and may not be easily manufactured and assembled.
[0005] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional exercisers.
[0006] The primary objective of the present invention is to provide an exerciser including a tiltable seat support for simulating the upward climbing and/or the down hill riding exercising.
[0007] The other objective of the present invention is to provide an exerciser including an adjustable resistive device for applying different resistive forces against the foot pedal devices or the like.
[0008] The further objective of the present invention is to provide an exerciser including an adjustable resistive device for applying a greater resistive force against the foot pedal devices or the like while simulating the upward climbing exercising, and/or for applying a less resistive force against the foot pedal devices or the like while simulating the down hill riding exercising.
[0009] In accordance with one aspect of the invention, there is provided an exerciser comprising a base, a post including a lower portion pivotally secured on the base with a pivot axle, for allowing the post to move either forward or rearward to simulate a down hill riding exercising or an upward climbing exercising, a seat cushion supported on the post, and means for rotating the post forward and rearward about the pivot axle, to simulate the down hill riding exercising and the upward climbing exercising.
[0010] A barrel is further provided and secured to the post for supporting the seat cushion. The seat cushion includes a seat tube secured in the barrel, for supporting the seat cushion on the barrel of the post.
[0011] The post includes a rearward extended shank, the barrel is secured on the shank. The post includes a handle for supporting an upper portion of a user.
[0012] The rotating means includes a lever having a first end pivotally secured to the post, and having a second end, and means for actuating the second end of the lever to rotate the post about the pivot axle.
[0013] The actuating means includes a spindle rotatably supported on the base, means for coupling the spindle to the second end of the lever, and means for forcing the spindle to actuate the second end of the lever to rotate the post about the pivot axle.
[0014] The forcing means includes a pair of cranks secured to the spindle, and a pair of foot supports secured to the cranks for rotating the spindle. The coupling means includes a gear transmission coupled between the spindle and the second end of the lever.
[0015] The gear transmission includes a pinion secured on the spindle and rotated in concert with the spindle, a gear rotatably supported on the base with a pivot shaft and coupled to the pinion, the second end of the lever is rotatably secured to the gear and offset from the pivot shaft. The gear transmission further includes at least one pair of pinion and gear rotatably supported on the base with a pivot rod and engaged with the gear and the pinion respectively.
[0016] The base includes a base frame disposed thereon for supporting the gear transmission. The lower portion of the post is rotatably secured on the base frame with the pivot axle.
[0017] A device is further provided for applying a resistive force or an changeable resistive force against the post. The resistive force applying means includes a flywheel rotatably supported on the base, and a resistive strap partially engaged over the flywheel and having a first end secured to the base and a second end secured to the post, for allowing the resistive strap to be released from and to be further forced against the flywheel when the post is rotated forward and rearward about the pivot axle to simulate the down hill riding exercising and the upward climbing exercising.
[0018] Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.

[0022]
[0023] Referring to the drawings, and initially to FIGS.
[0024] A weight or a paddle wheel, or a flywheel
[0025] A gearing transmission
[0026] A seat support
[0027] The post
[0028] A resistive device, such as a resistive strap
[0029] It is to be noted that the typical exercisers include a seat post
[0030] Accordingly, the exerciser in accordance with the present invention includes a tiltable seat support for simulating the upward climbing and/or the down hill riding exercising, and including an adjustable resistive device for applying different resistive forces against the foot pedal devices or the like. The adjustable resistive device may apply a greater resistive force against the foot pedal devices or the like while simulating the upward climbing exercising, and/or for applying a less resistive force against the foot pedal devices or the like while simulating the down hill riding exercising.
[0031] 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.
