Abstract

An improved fan fitness cycle consists of a base, a fan damping mechanism, a trampling drive mechanism, a grip and a seat. The fan damping mechanism includes a brake disc with small diameter, a plurality of fixed flake levers axially extending from both sides of the brake disc and a damping control mechanism. The utility model, with simplified process of production and low cost, can save much cost of low noise brake filament band, stabilize the brake disc and minimize the noise from braking with fast speed.

Description

Improved fan exercycle

The utility model relates to a kind of fitness equipment, relates in particular to the stable not beat of brake of a kind of cost that can significantly save low noise brake silk ribbon portion, brake disc, the noiseless improved fan exercycle of braking at a high speed.

Shown in Figure 1, for commonly using the front view of fan exercycle.Its primary structure comprises that a support 91, a pair of handle 92, a pair of interlock cross bar 931, a seat 93, a stampeding section 94, a front-wheel 95 and link the chain 96 of this stampeding section 94 and this front-wheel 95.Wherein, front-wheel 95 is that the wheel frame of employing Regular Bicycle is main, be provided with tens or how radial thin bar 951 on it approximately, several 951 on the thin bars of being separated by are provided with a blade 952, when running up, can produce the windage that is directly proportional with rotating speed, reach the effect of body-building with this front-wheel 95 of box lunch, but, but exist front-wheel 95 assembling cumbersome and can't increase the shortcoming of resistance.

Fig. 2 is the schematic perspective view that another kind is commonly used the fan exercycle.Also comprise on the structure that a support 91, a pair of handle 92, a pair of interlock cross bar 931, a seat 93, a stampeding section 94, a plastic cement front-wheel 97 and link the chain (not shown) of this stampeding section 94 and this plastic cement front-wheel 97.Yet this plastic cement front-wheel 97 comprises the inner vanes 972 and a pair of ventilation over cap 973 of an outer edge 971, several and this outer edge 971 one ejection formations again.Like this, can control the controller 99 of these brake silk ribbon 98 elasticities by a brake silk ribbon 98 and, then the length of this brake silk ribbon 98 must be walked around more than outer edge 971 half-turns of this front-wheel 97.

When rotating at a high speed because all rotations at a high speed of outer edge 971, several pieces inner vanes 971 and a pair of ventilation over cap 973 of this plastic cement front-wheel 97, in case other people brothers run into accidentally, will be injured, very dangerous.Simultaneously, because inner vanes 971 is in an enclosure space, the windage during rotation limited (be commonly called as and eat) less than wind, thus exist windage little, the shortcoming of body-building effect difference.

Again, the external diameter of supposing this plastic cement front-wheel 97 is 40 centimeters, and then the length of half circumference of these brake silk ribbon 98 these plastic cement front-wheels 9 of contact is (3.1416 * 40)/2=62.8 centimetre.So this brake silk ribbon 98 is wanted 62.8 centimeters long at least, because the brake silk ribbon is very expensive, so cost is high.

Secondly, the plastic cement front-wheel 97 of this plastic cement system is when running up, if these brake silk ribbon 98 tensions, torsion is very big, can make whole plastic cement front-wheel 97 produce beat.

In addition, because outer edge 971 surface metals of plastic cement front-wheel 97 are coarse, and be difficult for bearing concentrated immense pressure, therefore, in fact can add the smooth steel disc (not shown) of a slice, two ends lock with two screw (not shown) again, yet, this two screw forms protuberance, one side meeting scratch brake silk ribbon 98, the irritating noise in the time of can causing high speed rotating on the other hand.

Therefore, the utmost point is waited to develop new product and is commonly used the above-mentioned shortcoming that the fan exercycle exists with solution.

Main purpose of the present utility model is, a kind of improved fan exercycle is provided, and can significantly save the cost of low noise brake silk ribbon portion, and the stable not beat of the brake of brake disc.

To shown in Figure 6, the utility model comprises that a pedestal 10, a fan damping mechanism 20, trample driving mechanism 30, leader 40 and a seat 50 as Fig. 3.

This pedestal 10 has a first half 11 and one latter half of 12, the precalculated position of this first half 11 be pivoted a fan damping mechanism 20 and a pair of upwardly extending handle 40, this precalculated position of latter half of 12 are pivoted and one trample a driving mechanism 30 and a upwardly extending seat 50.

This fan damping mechanism 20 has the follower 22 that a driven axle 21 and is fixed in this driven axle.

This trample driving mechanism 30 have a driving shaft 31, be fixed in this driving shaft 31 driving wheel 32, a pair ofly walk around the actuated element of this driving wheel 32 and this follower 22, in order to drive 20 rotations of fan damping mechanism by this extended tread portion 33 in driving shaft 31 both sides and one.

Fan damping mechanism 20 of the present utility model comprises:

One is fixed in the brake disc 60 of this driven axle, and the outer rim of this brake disc 60 is provided with a continuous smooth groove 61, and the radius of this brake disc 60 is defined as first radius R 1.

Several are respectively by the radially extended substantially vanes fixed bar 70 in these brake disc 60 both sides, the vanes fixed bar 70 of this two side is symmetry each other, each vanes fixed bar 70 is provided with a windage blade 71, the outermost end of this fixed bar 70 is defined as second radius R 2 to the distance of this driven axle 22, and this second radius R 2 equals more than four times of first radius.

One damping control apparatus 80, comprise that the ribbon element 81 and of this brake disc 60 of a pile warp can adjust the controlling element 82 of the elasticity of this ribbon element 81, on this ribbon element 81, be provided with the brake silk ribbon portion 83 of a low noise, in order to strain at or to loosen this brake disc 60 to produce suitable resistance.This controlling element 82 is a located by prior art, so do not give unnecessary details.

Certainly, in the utility model, connect a pair of retainer ring 72 on the outer end of these several vanes fixed bars 70.This metal retainer ring 72 can respectively be strengthened the structure of vanes fixed bar 70 on the one hand, and the rotary inertia in the time of also can increasing rotation allows the trample sense of user when running up stablize smooth.
