Thus, the need for improvement still exists.
- It is therefore one object of the invention to provide a folding step exerciser comprising a main frame for placement on a surface and comprising a brace interconnecting a front end and a rear end and a pair of handlebars extending from a top end of the brace; a transmission device comprising two coaxial drive shafts disposed on both sides of the brace respectively, a first rotating shaft disposed below the drive shafts, a first wheel coaxial with the first rotating shaft, a first belt for linking the drive shafts and the first wheel, a second wheel coaxial with the first rotating shaft, a connection rotating shaft disposed between and driven by the drive shafts, a third wheel disposed between the drive shafts adjacent to the connection rotating shaft, a second belt for linking the second wheel and the third wheel, a roller for guiding the second belt, and a flywheel operatively connected to the connection rotating shaft; two length adjustable pedals disposed on both sides of the main frame respectively, each length adjustable pedal having one end pivotably secured to a front portion of the main frame; a pulley disposed below the transmission device; a main belt for linking the pulley, the drive shafts, and the pedals; a magnetic damping device comprising a knob on the main frame, a damping member spaced from and partially put on the flywheel, the damping member including a magnetic member for attracting the flywheel, and a rope interconnecting the knob and the damping member; a sensor disposed in close proximity to one of the length adjustable pedals for sensing a pedaling motion of one of the length adjustable pedals; and a numeric display mounted between the handlebars for displaying a count of the pedaling motion of one of the length adjustable pedals sensed by the sensor; wherein a turning of the knob either decreases or increases a rotating speed of the flywheel; and wherein the pedaling motion of the length adjustable pedals rotates the drive shafts via the main belt so as to activate the transmission device which in turn rotate the connection rotating shaft, the first wheel, the first rotating shaft, the second wheel, the third wheel, and the flywheel sequentially.
- The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
-
FIG. 1 is a side elevation of a folding step exerciser according to the invention; -
FIG. 2 is a perspective view of the folding step exerciser with guard frame removed; -
FIG. 3 is a side elevation of theFIG. 2 ; -
FIG. 4 is a front view of a lower portion ofFIG. 2 ; -
FIG. 5 schematically depicts operation of the transmission assembly of the transmission device; -
FIG. 6 is a side elevation showing the folded step exerciser; -
FIG. 7 is a side elevation showing a woman using the folding step exerciser for exercise; -
FIG. 8 shows a lower portion ofFIG. 3 for illustrating length adjustment of the tube; and -
FIG. 9 is a perspective view of a conventional step exerciser. - Referring to
FIGS. 1 to 8 , a folding step exerciser in accordance with the invention comprises the following components as discussed in detail below. - A
main frame 1, atransmission device 2, apedal assembly 3, apulley 4, amain belt 5, amagnetic damping device 6, and anumeric display 7 are provided. Themain frame 1 is rested on the ground and comprises abrace 12 interconnecting a front end and a rear end, a pair ofhandlebars 11 extending from a top end of thebrace 12, and aguard frame 13 for shrouding thetransmission device 2. - The
transmission device 2 comprises adrive shaft assembly 21 disposed on two sides of thebrace 12 and including twocoaxial drive shafts 211 disposed on two sides of thebrace 12 respectively, atransmission assembly 22 disposed between thedrive shafts 211 and including a first rotatingshaft 221 disposed below thedrive shafts 211, afirst wheel 224 coaxial with the first rotatingshaft 221, afirst belt 227 for mechanically linking thedrive shafts 211 and thefirst wheel 224, asecond wheel 223 coaxial with the first rotatingshaft 221, aconnection rotating shaft 225 disposed between and driven by thedrive shafts 211, athird wheel 222 disposed between thedrive shafts 211 adjacent to theconnection rotating shaft 225, asecond belt 226 for mechanically linking thesecond wheel 223 and thethird wheel 222, aroller 229 for guiding thesecond belt 226, and aflywheel 228 operatively connected to theconnection rotating shaft 225. - The
pedal assembly 3 comprises twofoot plates 30 disposed on both sides of themain frame 1 respectively. Eachfoot plate 30 is pivotably secured to a front portion of themain frame 1 by atube 31 having a length can be adjusted by fastening or unfastening athumb screw 32. The greater of the length of thetube 31 the greater of the pedal cycle and vice versa. - The
pulley 4 is disposed below thetransmission device 2. Themain belt 5 links thepulley 4, thedrive shafts 211, and thetubes 31. Themagnetic damping device 6 comprises aknob 61 on themain frame 1, adamping member 62 spaced from and partially put on theflywheel 228 and including amagnetic member 621 for attracting theflywheel 228, and arope 63 interconnecting theknob 61 and thedamping member 62. Thus, for example, a clockwise turning of theknob 61 can increase a distance between themagnetic member 621 and theflywheel 228 so that a resistance for rotating theflywheel 228 can be decreased (i.e., theflywheel 228 may increase rotating speed). To the contrary, a counterclockwise turning of theknob 61 can decrease the distance between themagnetic member 621 and theflywheel 228 so that the resistance for rotating theflywheel 228 can be increased (i.e., theflywheel 228 may decrease rotating speed). Asensor 71 is disposed in close proximity to thetube 31 so that a pedaling motion of thefoot plate 30 can be sensed and counted. The count is further displayed on thenumeric display 7 between thehandlebars 11 for user viewing. - The operation of the folding step exerciser is detailed below. A use may pedal for exercise by stepping on the
foot plates 30 upward and downward in a cyclic manner. And in turn, thedrive shafts 211 may rotate via themain belt 5. Further, thetransmission device 2 may activate to rotate theconnection rotating shaft 225, thefirst wheel 224, the firstrotating shaft 221, thesecond wheel 223, thethird wheel 222, and theflywheel 228 in sequence. - While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
