Claim Text:
1. An integral vertical stepper, comprising: a main vertical structure comprising two parallel rectangular profiles that are configured to support at least 120 kg and the two parallel rectangular profiles are linked together by a bridge arranged at a top potion thereof; a vertical rectangular profile; a first bent tube arranged horizontally to form a front base of the integral vertical stepper, the first bent tube being fixed to a bottom part of the parallel rectangular profiles; a second bent tube arranged horizontally to form a rear base of the integral vertical stepper, the second bent tube being fixed to a bottom part of the vertical rectangular profile; a mechanical system; a pedal system; a C-shaped part comprising triangular faces arranged on a front face of the vertical rectangular profile, the C-shaped part being attached to a center square profile with a rotatable rod that is configured to lock the integral vertical stepper in an operative configuration and to ensure maximum safety of the integral vertical stepper structure; a second square profile that houses the square profile to form a telescopic rod; three wheels housed in the bridge to guide two parallel poles passing through the top face of the bridge with an upwards and downwards movement; two square profiles each placed on each side of the integral vertical stepper, the two square profiles configured to be coupled to the parallel poles, and to form a telescopic mechanism providing five levels of extension, the telescopic mechanism configured to achieve an ideal length and a required height for a user when performing the upwards and downwards movements associated with the integral vertical stepper; a tubular part horizontally arranged on each top face of the square profiles and configured as a handle support; the pedal system comprising two pedal bases and two pedals, each pedal base configured to receive one of the two pedals, two C-shaped supports arranged and configured to each hold one of two pedal based and one of the two pedals of the pedal system; two sets of three wheels, each arranged on each C-shaped support to engage sides of each one of the two parallel rectangular profiles such that said parallel rectangular profiles act as rails; the mechanical system comprises a plastic pulley with diameter between 9.5 cm and 10.2 cm, the plastic pulley comprises a channel or throat having a series of grooves radially disposed to hold a metal wire coated with a plastic layer, the mechanical system being fixed such the plastic pulley is connected to a C-shaped part with triangular faces, the C-shaped part arranged in a center in a front inner part of the integral vertical stepper and the plastic pulley being fixed to an L-shaped extension such that the plastic pulley is arranged between the two parallel rectangular profiles and the vertical rectangular profile; two inserts each having a threaded tip arranged on a rear face of the two C-shaped supports; and two steel connectors placed on each end of the inserts with the threaded tip configured to connect to each pedal on each end of the coated metallic wire such that a weight of the user applied to the pedals generates tension on the coated metal wire to generate movement in conjunction with the plastic pulley together with the mechanical system of the integral vertical stepper, and said mechanical system together with the pedal system is configured as a system, wherein a force exerted by the user on the pedals affects inversely and directly proportional on the mechanical system causing elements and parts of the mechanical system to displace in a uniform and coordinated way, including the two parallel poles along with the two square profiles attached to the C-shaped support.
