Abstract

The invention relates to a micro-stepping exercise bicycle belonging to the field of bicycles. The front end of a linear frame without a seat is connected with a direction lever, and the other end of the linear frame is connected with a rear wheel shaft to form a body frame; a body is not provided with a seat, and the riding posture is stand-up stepping; the inner part of a main gear comprises two unilateral clutch bearings which are respectively connected with a left front shaft and a right front shaft to enable the main gear to be capable of moving in a stepping mode; a spacing outer ring is matched with a spacing inner baffle to limit the motion amplitude of a pedal; the pedal is combined with a half instep fixing plate to fix the instep, and the design of the half instep fixing plate enables a user to get off the exercise bicycle conveniently and safely; bearing outer rings at two ends of the shaft are respectively fixed on a bearing groove of the linear frame without a seat; the main gear and a center shaft gear are meshed mutually to drive a chain wheel on each shaft to drive a rear wheel forwards through a chain; and multiple shafts are matched to reduce the volume of the gear and the chain wheel on each shaft, thereby reducing the volume of the body. The technical method reduces the manufacturing cost, the body is light and has small volume, the user can get off the bicycle more conveniently in an emergency, and the invention achieves the purposes of entertainment, riding instead of walking and safe exercise.

Description

Miniature Treadlemill

Affiliated technical field

The present invention relates to a kind of miniature step bicycle of can body-building and riding instead of walk.

Background technology

At present, the standard bicycle contour structures mainly connects front and back wheel by vehicle frame, drives main combination by stretcher, pedal shaft, chain wheel, thereby makes bicycle to overtake by the both feet chain wheels that 360 degree motions drive on the pedal shafts that treadle.But standard bicycle scrunches effort, and vehicle body is heavy, and is inconvenient up and down, gymnastics is not strong, and motion of foot has certain motion dead angle under steam.

Summary of the invention

In order to overcome motion dead angle in the standard bicycle, scrunch effort, to drive inconvenience etc., the invention provides a kind of miniature stepping type body-building vehicle, it has not only solved the dead angle when standard bicycle drives, can also utilize people's self body weight to be converted into driving power fully, change the lighter driver of convenience of contour structures volume simultaneously and driven.

The technical solution adopted for the present invention to solve the technical problems is: the front end that yi word pattern does not have seat coach frame 20 combines with direction lever 28, and the rear end combines with hind axle 30, more than constitutes the main body frame of body-building vehicle.Main gear 1, left side one-way clutch bearing 23, right one-way Engaging-and-disengaging bearing 24, left front axle 2, mutually combining of front right axle 11 make both feet stepping type motion up and down; The amplitude that making the motion of marking time that mutually combines that spacing outer back-up ring 12, spacing interior retaining 13, yi word pattern do not have seat coach frame 20, left front axle 2, front right axle 11 is controlled in 90 degree; The combination of stretcher 8, half instep adapter plate 9, torsion spring 26, up-down adjustment point 27 can make stretcher together lift with both feet; Both feet scrunch stretcher 8 rotates left front axle 2, front right axle 11, main gear 1, thereby drive the mass motion of axis 5, middle shaft gear 14, axis sprocket wheel 4, rear axle 18, rear axle minor sprocket 19, rear axle hinge wheel 6, hind axle sprocket wheel 21, drive forwards thereby reach trailing wheel 22; The multiaxis routing motion of left front axle 2, front right axle 11, axis 5, rear axle 18, hind axle 30 has dwindled gear and the sprocket wheel volume ratio on the axle, and the vehicle frame volume is also diminished thereupon; Adopt yi word pattern not have seat coach frame both hands and hold direction lever, both feet stand in body erect on the stretcher, and both legs are rotated or lifted the back simultaneously with sinking naturally downwards of health inertia, thereby have not had to sit the weight and volume that bar and seat have reduced body-building vehicle.

The invention has the beneficial effects as follows, can make the comparatively light safe driving bicycle of human body.

Specific implementation method

Below in conjunction with accompanying drawing implementation method of the present invention is further specified.

The front end that yi word pattern does not have seat coach frame 20 combines with direction lever 28, and direction lever connects front-wheel 29; The rear end combines 30 with hind axle, and hind axle connects trailing wheel 22, more than constitutes the body-building vehicle main body frame.

The outer ring that left side one-way clutch bearing 23 and 24, two one-way clutch bearings of right one-way Engaging-and-disengaging bearing are equipped with in main gear 1 inside is separately fixed at main gear 1 by repacking; Two one-way clutch bearing cones are fixed with the inside end of left front axle 2 front right axle 11 respectively by repacking; Axle bearing 3, spacing interior retaining 13, stretcher connecting rod 7 before the outside end of left front axle front right axle passes respectively in order; Spacing outer back-up ring 12 is fixed on yi word pattern according to the size of retaining 13 in spacing by screw hole 25 not to be had on the seat coach frame 20.Be made up of middle shaft gear 14 and axis sprocket wheel 4 on the axis 5, the two ends of axis combine with bottom bracket bearing 15 inner rings respectively.Be made up of rear axle minor sprocket 19 and rear axle hinge wheel 6 on the rear axle 18, the rear axle two ends combine with back axle bearing 17 inner rings.Form by hind axle sprocket wheel 21, trailing wheel 22 on the hind axle 30.

About yi word pattern does not have the seat coach frame and is divided into two 20, the outside race at each two ends is separately fixed at yi word pattern vehicle frame in-to-in front axle bearing groove 31, bottom bracket bearing groove 32, rear axle bearing groove 33, hind axle bearing groove 34.When all drive parts and are installed in yi word pattern and do not have the seat coach frame,, fix by screw or other modes two merging about vehicle frame.

Installed half instep adapter plate, 9, half instep adapter plates 9 on the stretcher 8 additional and manufactured according to human body instep structure, the effect of half instep adapter plate is in order to get off conveniently; Stretcher 8 and the half instep adapter plate 9 effect control pin by torsion spring 26 stand in the elasticity on the stretcher; Elasticity up and down by up-down adjustment point 27 adjustings half instep adapter plate 9.

More than the combination of each part when making stretcher 8 mark time motion up and down, retaining 13 rotates in 90 ° of angles with the left front axle 2 of the engagement limits of spacing outer back-up ring 12, front right axle 11 in spacing, effect by left side one-way clutch bearing 23 and right one-way Engaging-and-disengaging bearing 24 makes main gear 1 rotate shaft gear 14 in the also interlock to a direction, thereby makes the sprocket wheel on axis 5, rear axle 18, the hind axle 30 drive the effect that trailing wheels 22 drive forwards by axis and rear axle chain 16, rear axle and hind axle chain 10.
