BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to an exerciser, and more particularly to an exerciser
having an adjustable seat for being easily adjusted by users.
2. Description of the Prior Art
[0002] Various kinds of typical exercisers, such as cycle exercisers have been developed
and comprise a seat disposed thereon for supporting users. For allowing the users
to be comfortably supported on the seat, various kinds of typical cushioning devices
have been provided to cushion the seat, and thus to cushion the users.
[0003] For example, U.S. Patent No. 6,089,656 to Hals discloses one of the typical cycle
exercisers comprising a seat pivotally disposed or supported thereon with a parallelogrammic
structure for supporting users, and a spring-biasing cushioning device disposed in
the parallelogrammic structure for cushioning the seat and thus the users.
[0004] However, the parallelogrammic structure may not be solidly secured to the seat or
to the other supporting bases, such that the seat may not be solidly secured to the
supporting bases, and such that the users may not be stably supported on the supporting
bases with the parallelogrammic structure.
[0005] The applicant has developed another typical cycle exerciser which has been allowed
and issued as U.S. Patent No. 6,565,487 to Kuo, and which also comprises a seat pivotally
disposed or supported thereon with a parallelogrammic structure for supporting users,
and a lock rod for locking the parallelogrammic structure to the supporting bases
at any selected heights or positions.
[0006] However, when it is required to adjust the parallelogrammic structure to the supporting
bases at the selected heights or positions, the users have to move away from the seat,
and then have to actuate the lock rod and to move or adjust the parallelogrammic structure
relative to the supporting bases to the required or selected heights or positions,
and then to release the lock rod, to allow the lock rod to lock the parallelogrammic
structure to the supporting bases at the required or selected heights or positions.
[0007] The cited typical cycle exercisers have no support devices to solidly support the
parallelogrammic structure relative to the supporting bases at the required or selected
heights or positions, and have no adjusting device for allowing the users to easily
and readily adjust the parallelogrammic structure relative to the supporting bases
to any required or selected heights or positions.
[0008] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages
of the conventional cycle exercisers.
