Stepper with wave type vibrator

Stepper with wave type vibrator description/claims

1. Field of the Invention

The present invention relates, in general, to steppers with wave type vibrators and, more particularly, to a motorized stepper with a wave type vibrator, which enables a user to aerobically exercise his/her feet or other parts requiring training to strengthen the parts or reduce the body fat thereof, using both the strong wave type vibrating motion of a step board and an improved multi-level control system, thus promoting an improvement in the base metabolic rate of the user's body and realizing effective body fat reduction and effective increase in muscular power.

2. Description of the Related Art

Generally, a variety of exercise machines or health machines may be provided in homes and health clubs. Thus, users can exercise using desired machines to harden and strengthen their bodies.

Conventional exercise machines or health machines are classified into two types: hand-operated machines, which are manually operated by users' power while the users exercise using the machines; and automatic machines, which are automatically operated using automatic mechanisms to reduce body fat and relax or contract the muscles of users and thus give exercise effects to the users.

In recent years, a variety of steppers, which are classified as automatic exercise machines, have been proposed to provide vibrating motions or shaking motions to users, thus reducing body fat or relaxing muscles and, further, relieving users' fatigue and thereby providing exercise effects to the users.

However, conventional steppers typically use small capacity motors and simple rotating links, so that the conventional steppers are problematic in that they have only a short life expectancy, and provide only weak and simple vibrating motions. Particularly, in the related art, the steppers have been studied and designed to realize only body fat reduction and hardening of users' muscles, so that the conventional steppers cannot realize a large variety of wave type vibrating motions or improved vibrating cycles. Further, the conventional steppers are not equipped with additional functions, demanded by users searching for healthy lifestyles. Thus, an exercise machine, which has a wave type vibrator and realizes multiple functions and can provide improved exercise effects, is demanded.

Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, and an object of the present invention is to provide a motorized stepper with a wave type vibrator, which enables a user to aerobically exercise his/her feet or other parts requiring training to strengthen the parts or reduce the body fat thereof, using both the strong wave type vibrating motion of a step board and an improved multi-level control system, thus promoting an improvement in the base metabolic rate of the user's body and realizing effective body fat reduction and effective increase in muscle power.

In order to achieve the above object, the present invention provides a motorized stepper, which is used by a user to reduce body fat or increase muscular power using a vibrating unit, the stepper comprising: a stepper frame, comprising a box-shaped stand which is open on part of an upper surface thereof, with a depression defined in the stand; a central column securely standing on a predetermined portion of the upper surface of the stand, with a perforated receiver provided in an outer circumferential surface of the central column at a predetermined location; and a handle arm extending outwards from each of the left and right sides of the central column at a first end thereof and being secured to an associated portion on the upper surface of the stand at a second end thereof; a drive unit, comprising a step board installed in the depression of the stand, with a plurality of acupressure protrusions and a far-infrared lamp provided on the upper surface of the step board; a drive motor mounted to the upper surface of a bottom wall of the step board and implemented as a brushless motor (BLDC motor); a drive belt wrapped around an output shaft of the drive motor to be rotated in conjunction with the output shaft of the drive motor; a driven pulley connected to the output shaft of the drive motor by the drive belt wrapped around the driven pulley; a rotating shaft rotated in conjunction with the driven pulley and divided into left and right shaft parts based on the driven pulley; and a vibrating bracket having an actuating link to be actuated in conjunction with the rotation of the rotating shaft; and a control unit, comprising a course setting unit for commanding the drive unit to execute four different vibrating motions and controlling power supply for the drive unit; and a far-infrared lamp controller for controlling a preset temperature and a preset operating time for the far-infrared lamp of the step board.

In the stepper, the stepper frame may further comprise: a power lamp provided on the outer circumferential surface of the central column at a predetermined location.

In the stepper, the handle arm of the stepper frame may be provided with a heating wire to heat the handle arm to the preset temperature and to be turned on or off under the control of the control unit.

In the stepper, the step board of the drive unit may be provided with a protective depression and a transparent window for protecting the far-infrared lamp.

In the stepper, the control unit may further comprise both an automatic power-saving controller and a heating wire temperature controller.

The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description when taken in conjunction with the accompanying drawings, in which:
