Description
The present invention relates to a kind of bicycle locomotory apparatus, particularly relate to a kind of directly the driving and hinder the control wheel to carry out the single-axle bicycle type sports apparatus of bicycle motion with the single shaft type of drive.
The common bicycle locomotory apparatus overwhelming majority is to be the structure that twin shaft drives at present, promptly as shown in Figure 1.Promptly this bicycle locomotory apparatus is to trample the function of first rotating shaft 2 to drive a big belt pulley 3 rotations through foot pedals 1 earlier, and then via small belt pulley 6 places of a binding belt 4 with transmission of power to the second rotating shaft 5 places of this big belt pulley 3, because this small belt pulley 6 is to be combined into one with a resistance control wheel 7 through an one-way clutch apparatus (not shown), so when this foot pedals 1 forward is trampled, this resistance control is taken turns 7 and can be the function that forward rotates synchronously, and the resistance control device (not shown) that cooperation is established in addition hinders the effect that the control bicycle moves to reach; Otherwise when this foot pedals 1 reverse trampling, it can form the phenomenon that idle running is trampled through the effect of this one-way clutch apparatus.
No doubt this kind bicycle locomotory apparatus commonly used can reach the effect of bicycle motion really, but because it is except being provided with the indispensable resistance control wheel of a resistance control bicycle locomotory apparatus institute, it still is provided with a big belt pulley in addition, and this big belt pulley still must could be controlled the wheel place with transmission of power to this resistance with a binding belt, so it is except constructing comparatively complexity, it also can cause the waste situation in man-hour on assembling operation; Even adding of these members also can form the high phenomenon of manufacturing cost, thus how effectively to save the flow process and the man-hour of manufacturing operation, and effectively reduce production cost of products, be to become very important problem of dealer.
Though also there is the dealer to develop a kind of single axis foot treadmill exercising machine of convenient type, but therefore plant the function that exercising machine also can't provide reverse idle running, that is to say, no matter this kind exercising machine is just changeing or is reversing the rotational resistance that all presents same degree, so it also can't cooperate common people's issuable reverse phenomenon of trampling in the process of trampling, so plant the bicycle locomotory apparatus that structure also can't really be applied to hinder the control formula.
In view of this, the inventor is with its experience of being engaged in the sports equipment design for many years and making, and the active research improvement is created a kind of single-axle bicycle type sports apparatus thereby grind.
Goal of the invention of the present invention, provide a kind of single-axle bicycle type sports apparatus, make structure, to simplify the locomotorial unitary construction of resistance control bicycle greatly through this resistance control wheel of single shaft transmission, thereby when effectively saving the locomotorial worker of this bicycle, and reach the effect that reduces cost of goods manufactured.
A kind of single-axle bicycle type sports apparatus is made up of a support body, a resistance control wheel, a unidirectional drive device, a rotating shaft and two rotating shaft fixtures, it is characterized in that:
This support body is made of a bracing frame that is respectively equipped with seat cushion and handle in the appropriate position, in addition the appropriate position of this bracing frame also is respectively equipped with two symmetrical lugs, and on this two lug and be respectively equipped with and have proper width and the corresponding rotating shaft groove that bridges;
This resistance control wheel is to be provided with the disk that connects central duct by a central part to be constituted, and this central duct is except being provided with a hole slot that can set firmly for bearing in its front end place, and its rear end also further extends back and forms the coaxial hollow circuit cylinder of a tool suitable length;
This unidirectional drive device is to be made of a hollow unit body that can be set in this hollow circuit cylinder outside, this unidirectional drive device is except being can drive simultaneously this resistance control wheel rotation when just changeing, and it then is to be the idling structure that can't drive this resistance control wheel backwards rotation when reversing;
This rotating shaft is except being circular pin by suitable external diameter of a tool and suitable length is constituted, the appropriate position of this circular pin also is provided with a coaxial connector, when making this rotating shaft pass the central duct of this unidirectional drive device and resistance control wheel with an end cover of its circular pin, but this coaxial connector of mat and this rotating shaft and this unidirectional drive device are combined into one; In addition this circular pin bridges the groove except the sleeve pipe that is nested with suitable length in its two ends respectively makes the rotating shaft of crossing over the set lug of this support body, and its appropriate position, outside also is respectively equipped with external thread part and can sets firmly therebetween fixed groove for foot pedals;
These two rotating shaft fixtures are made of a hollow short column that is arranged with bearing, this hollow short column and be provided with the hole that several vertically run through its wall body in addition, these two rotating shaft fixtures are covered therebetween for this rotating shaft terminal with its set bearing respectively, and the inboard that makes this bearing is when contacting with the outer end of this sleeve pipe, can several screws of further mat run through the set hole of this rotating shaft fixture and this rotating shaft fixture is locked in the outside of the set lug of this support body, on the set external thread part of this rotating shaft terminal, lock hold-doun nut subsequently, and establish foot pedals respectively at this fixed groove place lock, can form a single-axle bicycle type sports apparatus.
Single-axle bicycle type sports apparatus of the present invention, be that direct mat foot pedals is rotated to drive rotating shaft, and then the set coaxial connector of mat is to order about the function that the unidirectional drive device carries out forward drive or reverse idle running to this resistance control wheel, thereby make this resistance control wheel be able to cooperate with ad hoc resistance control device, reach the motion effect of resistance control bicycle, so the present invention has following advantage: except can simplifying the locomotorial unitary construction of bicycle greatly, also can reach the effect of effective reduction production cost because of the economization of partial component.
