Description

Body-building apparatus with oval track

The utility model relates to body-building apparatus, and the places such as front yard, school, office, independent social center for the elderly of being in of more clearly saying so make the body-building apparatus with oval track of flywheel rotation so as to body-building with the hand-held handlebar pedal pedal of stance.

The body-building apparatus with oval track structure in past is very complicated, and three cranks are arranged.No. 86215621 patent applications in Taiwan come to this.Simultaneously, the resistance during the pedal pedal is non-adjustable.That is to say that except pick up speed, body builder's work done or its amount of exercise can not arbitrarily be adjusted.And because the height of its handlebar can not be regulated, again to hold the push-and-pull of handlebar increased force will, fixedly the height of handlebar is to considerable people and improper during body-building, and the body builder can not arbitrarily heighten and turn down, and adaptability is relatively poor.

The purpose of this utility model is to overcome above-mentioned shortcoming and defect, provides a kind of simple in structure, good looking appearance, and safe and reliable, pedal power and amount of exercise can arbitrarily be adjusted, and not only are applicable to young and middle-aged people but also are applicable to old person's body-building; The height of handlebar also can be regulated, thereby applicable to the people's of different statures different requirements, adapts to wide body-building apparatus with oval track.

In order to achieve the above object, the utility model by base, be connected in frame, rack-mounted chain flywheel transmission mechanism on the base, be installed in the handle mechanism of frame front end and be installed in the crank axle of chain flywheel transmission mechanism and the free bearing of handle mechanism lower end between the pedal linkage constituted.Frame by the rear bearing, the end that are fixed on column on the base, are fixed on the column upper end be welded on that the last strut of the arc of column upper end, the front axle that is welded on the strut other end are in the charge of, an end is welded on that the other end on the base is welded on that front axle is in the charge of fall L shaped centre have the axis bolster about two upright struts form.Chain flywheel transmission mechanism by be installed in integral type crank axle in the rear bearing, be installed in sprocket wheel on the crank axle, be installed in about on two axis bolsters axis, be installed in pipe spreader on the axis, be fixed on flywheel on the pipe spreader and minor sprocket, installation and be engaged on chain on sprocket wheel and the minor sprocket, be fixed on the protective cover that is positioned at chain flywheel both sides on the frame and form.Handle mechanism by be installed in the front axle of front axle in being in the charge of, be installed in the front axle two ends about two axle sleeves, be welded on the lower end band free bearing on the axle sleeve two sleeve pipes, two handles and the grip thereof that are fastened in two sleeve pipes be installed formed.The pedal linkage by two pedal shafts that are installed in the crank two ends, be installed in two pedal axle sleeves, an end on two pedal shafts be welded on pedal shaft put the other end be hinged on the free bearing of sleeve pipe of handle mechanism about two connecting rods, be installed on the connecting rod about two pedals formed.This structure has only a crank, greatly simplifies.The protective cover of chain flywheel both sides was both attractive in appearance, can guarantee safety again, and was very reliable.

Be with around a friction on the wheel rim of flywheel.The upper end of friction band is with securing member or buckle the knot sheet and be fixed on the strut middle and upper part, and the lower end is installed in one and is fixed on can regulating of strut lower end and rubs and be with on the adjuster of the length on the wheel rim.

Adjuster can be by the nut seat of the band inner groove that is fixed on the strut bottom, be installed in the nut that has turret head or outer rim annular knurl round end that can rotate around it in the inner groove of nut seat and can not deviate from, pass the expansion screw that the hole on the strut is installed in the nut constitutes.The lower end of expansion screw has the transverse holes that the friction band can be passed.The side of transverse holes has screw.A holding screw that the friction band can be fixed in the transverse holes is installed in the screw.

After friction band two ends all are fixed, screw nut with hand or instrument, make it to press or gently be pressed on the wheel of flywheel thereby just can make the expansion screw lifting drive the friction band, also just increase or reduced to order about the resistance that flywheel rotates, so regulated at will body builder's amount of exercise.

The sleeve pipe of handle mechanism upper end also can plug-in mounting the lining of a belt length hole or elongated slot, wears concentric screw before back, sleeve pipe upper end is with holes, and the handle bottom has the height adjustment hole.The height adjustment hole that adjustment screw is passed the slotted hole of hole, lining of sleeve pipe front or elongated slot, handle successively is fastened on the screw of sleeve pipe back.

Unclamp and back out adjustment screw, handle is evacuated to suitable height, again expansion screw is inserted new height adjustment hole and tighten again, just regulated the height of handle.Very convenient.

During body-building, the people stands on the pedal, and the grip cover pushes hard and pulls handle, and pin is firmly pedaled pedal, pedal just successively drivening rod, pedal shaft, crank axle, sprocket wheel, chain drive the flywheel rotation at last, reach the purpose of body building.This moment, the movement locus of pedal was an ellipse.

Task of the present utility model comes to this and finishes.

But the resistance of the utility model pedal footboard drives flywheel, the height of handlebar be regulated at will all, and the requirement when not carrying out different gestures body-building to adapt to different physical orders in the same year of different statures or same people adapts to wide.Not only be applicable to young and middle-aged people, and be applicable to old person.Simple in structure, good looking appearance, safe and reliable.It can be widely used in the places such as family, office, school, gymnasium, independent social center for the elderly.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further to describe.

Fig. 1 is the surface structure schematic diagram of the utility model embodiment 1.
