As Fig. 1, the preferred embodiment of the utility model elliptical exercise machine is to include a support 1, to lead assembly 2, two pendulous devices 3, an adjusting device 4 and two and step on luggage and put 5.
This support 1 has one for being placed in a surface-supported bracing frame 11, reaches the dashboard bracket 12 of a vertically-arranged at these bracing frame 11 1 front ends.
This is led assembly 2 and has a flywheel 21, a rotating shaft 20 and two cranks 22.This flywheel 21 is arranged on the position of contiguous bracing frame one rear end, and this rotating shaft 20 is to run through flywheel 21, and this two crank 22 is affixed with rotating shaft 20 ends that pass flywheel 21 both sides.
This pendulous device 3 has a bar 31, a connecting rod 32, a motion guide rod 33 and a moving member 34 of mutual pivot knot respectively.Respectively this bar 31 is to form the pivot knot at one first pivot I place with middle part and dashboard bracket 12 and arranged on left and right sides respectively.Respectively this connecting rod 32 is with a rear end 321 and crank 22 pivots knot.Respectively this motion guide rod 33 is and connecting rod 32 1 front ends 322 and bar 31 1 lower ends 311 pivots knot, the state that makes connecting rod 32 front ends 322 keep down and hang.Respectively this moving member 34 is a ball roller at present embodiment, is to be hubbed on the position that connecting rod 32 front ends 322 hang downwards, and slides against on the plane.Making bar 31 is rotating shaft with first pivot I, see through motion guide rod 33 drivening rods 32 front ends 322 with moving member 34 along the plane forward and backward sliding, make the forward and backward stably swing of connecting rod 32.
This adjusting device 4 have one be fixed on motor 41, on support 1 bracing frame 11 be fixed on dashboard bracket 12 locating rack 42, an adjustment rack 43 and one with motor 41, adjustment rack 43 link extensible member 44.This locating rack 42 has two along prolonging the guide rod 421 that dashboard bracket 12 length directions extend and be positioned at dashboard bracket 12 and arranged on left and right sides.This adjustment rack 43 has more two perforations 431 that pass for guide rods 421, makes the adjustment rack 43 can be along guide rod 421 upper and lower displacements.This extensible member 44 has a sleeve 441 that is fixed on the adjustment rack 43, and one screws togather this sleeve 441 and connects the screw rod 442 of motor 41.
This is stepped on luggage and puts 5 and have a swing arm 51 of mutual pivot knot and a pedal shaft 52, part 53, an assembly pulley 54 and a pedal 55 respectively.Respectively this swing arm 51 is to form the pivot knot at one second pivot II place with a upper end 511 and adjustment rack 43 and arranged on left and right sides respectively.This pedal shaft 52 has an end 521 that extends to connecting rod 32 tops.Respectively this part 53 has an axostylus axostyle 531 and an assembly pulley respectively, this axostylus axostyle 531 is pivots and passes this bar 31 lower ends 311, this assembly pulley have one with the fixed framework 532 of axostylus axostyle 531 traversing through end, and two hub settings 532 of frameworks and with the sliding rollers 533 that close of swing arm 51.This assembly pulley 54 have one with the fixed framework 541 of pedal shaft 52 1 ends 521, and two hub settings 541 of frameworks and with the connecting rod 32 sliding rollers 542 that close.This pedal 55 is to be separately fixed on the pedal shaft 52.
Ginseng Fig. 2, Fig. 3, the stroke that swings when user's desire amplification motion, need only rotate with motor 41 drive screws 442, just can be when screw rod 442 screws togather at sleeve 441, drop-down adjustment rack 43 along the guide rod 421 of locating rack 42 to bottom offset, and this swing arm 51 can descend simultaneously second pivot II along the roller 533 of axle parts 53 with adjustment rack 43 downward slippages, dwindles the distance with a part 53.At this moment, because when the bar 31 of this pendulous device 3 and connecting rod 32, motion guide rod 33 forward and backward swinging, be to have the fixing amplitude of oscillation with crank 22 interlocks, therefore, this part 53 also immobilizes with the amplitude of oscillation L1 that pendulous device 3 swings are produced, so, when axle spare 53 is positioned at the position of contiguous second pivot II, the amplitude of oscillation L2 of this swing arm 51 can be exaggerated, and has the bigger amplitude that swings.
Whereby, the user stand on the pedal 55, hold bar 31, and to pedal shaft 52 bestow one forward, during backward skid force, just can make bar 31 is rotating shaft with first pivot I, see through motion guide rod 33 drivening rods 32 front ends 322 with moving member 34 along the plane forward and backward sliding, make connecting rod 32 with fixing angle and amplitude of fluctuation is forward and backward stably swings.Simultaneously, this swing arm 51 can be rotating shaft with second pivot II, drives pedal shaft 52 with bigger forward and backward the swinging of the stroke that swings, and makes pedal shaft 52 in the process of swinging, and slides against on the connecting rod 32 with roller 542.At this moment, because connecting rod 32 rear ends 321 are to be circular motion with crank 22, and pedal shaft 52 1 ends 521 are with roller 542 linearly motion on connecting rod 32, can make the pedal 55 that is arranged on the pedal shaft 52 be the elliptical orbit motion, make this user who stand on the pedal 55 can follow a bigger elliptical orbit motion.
Consult Fig. 5, Fig. 6, the stroke that swings when the user desires to dwindle motion, need only activate the motor 41 of adjusting device 4 equally by the instrument board on the dashboard bracket 12 (figure does not show), motor 41 drive screws 442 are rotated, just can be when sleeve 441 be soaring along screw rod 442, elect adjustment rack 43 along the guide rod 421 of locating rack 42 to top offset, and this swing arm 51 can be along the roller 5322 of axle parts 53 with adjustment rack 43 upwards slippages, make second pivot II rising simultaneously, prolong distance with axle part 53.At this moment, because the bar 31 of this pendulous device 3 is during with, motion guide rod 33 connecting rods 32 forward and backward swinging, be to have the fixing amplitude of oscillation with crank 22 interlocks, therefore, this part 53 also immobilizes with the amplitude of oscillation L1 that pendulous device 3 swing is produced, so, when axle spare 53 during away from second pivot II, the amplitude of oscillation L2 of this swing arm 51 can dwindle, and has the less amplitude that swings.
Whereby, the user stand on the pedal 55, hold bar 31, and to pedal shaft 52 bestow one forward, during backward skid force, just can make bar 31 is rotating shaft with first pivot I, see through motion guide rod 33 drivening rods 32 front ends 322 with moving member 34 along the plane forward and backward sliding, make connecting rod 32 with fixing angle and amplitude of fluctuation is forward and backward stably swings.And this swing arm 51 can be rotating shaft and under the situation that is subject to a part 53 with second pivot II, drives pedal shaft 52 with less forward and backward the swinging of the amplitude that swings, and makes pedal shaft 52 in the process of swinging, and slides against on the connecting rod 32 with roller 542.At this moment, because connecting rod 32 rear ends 321 are to be circular motion with crank 22, and pedal shaft 52 1 ends 521 are with roller 542 linearly motion on connecting rod 32, can make the pedal 55 that is arranged on the pedal shaft 52 be the elliptical orbit motion, make this user who stand on the pedal 55 can follow a less elliptical orbit motion.
