Abstract:
A multipurpose exercising apparatus adapted to provide various exercising postures in order to exercise different muscle groups of the human body, one muscle group at a time, the apparatus comprising:a rack, said rack comprising a main rod member linearly extending in a direction designated as X-axis direction, and at least one stand fastened to said main rod member and adapted to support said main rod member above a floor; a mattress unit, said mattress unit comprising a back mattress, a seat mattress, an adjustment mechanism, and a coupling mechanism, said back mattress and said seat mattress pivotally connected to each other, said adjustment mechanism adjusts tilting of said back mattress from said seat mattress any angle between said back mattress and said seat mattress, said coupling mechanism fastened to said seat mattress at a bottom side thereof and coupled to the main rod member of said rack to enable said mattress unit to be moved on said rack in the X-axis and fixable in selected positions along the main rod member; a damping unit mounted on said rack, said damping unit comprising a first actuating bar, a linking mechanism, and a damping force source device for providing resistance force, said linking mechanism having two opposite ends respectively coupled to said first actuating bar and said damping force source device adapted to enable the user to change positions of said first actuating bar with respect to said damping force source device and to receive a damping force when a force is applied to said first actuating bar; said coupling mechanism comprises a rotating mechanism for enabling said mattress unit to be rotated to a desired direction; said linking mechanism comprises a link and a connector, wherein said connector is pivotally connected to said rack, said link having one end thereof coupled to said first actuating bar, and an opposite end thereof pivotally connected to said connector, wherein a relative position of said link with respect to said connector can be changed to change position of said first actuating bar; and said damping force source device has one end thereof coupled to said rack, and an opposite end thereof coupled to said linking mechanism, such that upon actuation of force on said actuating bar, said damping force source device resists rotational motion of said connector.
