    Mountain bike
    The present invention relates to a bicycle, and in particular, to increase the driving force to be widely supplied as a mountain bike.
    In the conventional bicycle, only the rear wheels connected to the chain by the pedal of the pedal are driven to rotate with the pedal effort, and the driving force is transmitted. This is the rear wheel driving method in which most of the driving force is dependent on the pedal force of the pedal. The transmission is attached separately.
    In addition, only the rear wheels are driven by receiving pedal pedal force, which inevitably leads to a low propulsion force, which requires a lot of human body energy as a mountain bike which mainly relies on greater driving energy, that is, a stronger driving force. There was a need for a bicycle that could provide.
    Accordingly, a number of bicycles capable of simultaneously driving the front and rear wheels have been devised in the past, but most of them are rear wheels that drive the pedals, such as Korean Utility Model Publication Nos. 85-6629 and 94-3004. In addition, the front wheel was configured to be interlocked with the rotary handle, and by operating the steering wheel by rotating, the practical difficulties such as steering operation was almost absent.
    In addition, the rotational force of the rear wheels driven by the pedals of the pedals is transmitted to the front wheels by using the flexible shafts, and the front wheels are interlocked. The bicycle is not driven by being transmitted to the front and rear wheels at the same time. Instead, the front wheel is driven by the power transmission means using the flexible shaft. Therefore, the operability according to the power transmission is uncertain. It was difficult to expect its effectiveness.
    Therefore, in the present invention, by adopting the front and rear wheel simultaneous driving method, instead of the conventional rear wheel driving method, the pedal energy of the pedal acts simultaneously on the front and rear wheels, thereby maximizing the driving energy and requiring a strong driving force (that is, driving force). Primarily mountain bikes, they are widely available.

    Before and after the frame 2, the front and rear wheels 3 and 4 are respectively provided, and the rear wheels 4 are provided with chain sprockets 7 and chains 12 having pedals 9 and 9 'built on the pedal shaft 8. In the conventional bicycle 1 configuration, in which the rear wheels 4 are driven by the pedaling force of the pedals 9 and 9 ',
    The present invention connects the chain sprocket 7 and the front and rear wheels 3 and 4 of the pedal shaft 8 to which the pedals 9 and 9 'are coupled to the chain 12 of the pedals 9 and 9'. Maximizing the driving force by simultaneously acting on the front and rear wheels (3,4), so that the driving force to rotate them,
    Hereinafter, the configuration of the present invention will be described in more detail.
    Chain gears 10 and 11 are laid out on the front wheels 3 and rear wheels 4 and 6 of the rotating shafts 5 and 6 of the bicycle 1, and the chain gears 10 and 11 of the front and rear wheels 3 and 4, respectively. ) Is connected to the chain 12 on the caterpillar so as to interlock with the chain sprocket 7 arranged on the pedals 9 and 9 '.
    That is, the chain gear 11 of the rear wheel 4 side rotation shaft 6 is connected to the chain sprocket 7 on which the pedals 9 and 9 'are arranged, and the chain 12 coupled to the chain sprocket 7. ) Is extended and connected to the chain gear 10 on the front wheel (3) axis of rotation (5), in order to connect the chain 12 from the chain sprocket (7) to the front wheel (3) to adjust the direction of the front wheel (3) On the rotating shaft 5 of the front wheel 3, the chain 12 connected to the front wheel 3 is connected to the front wheel 3 via the upper and lower guide gears 13 and 14 below the steering frame 15 on which the front wheel 12 is installed. Connect with the chain gear (10).
    The lower guide gears 13 and 14 of the steering frame 12 for connecting the chain 12 from the chain sprocket 7 to the chain gear 10 side of the front wheel 3 to perform power transmission are provided with the installation frame ( 16) is installed directly below the steering frame 15 so that the chain 12 does not interfere with the steering of the front wheels 3, and the steering wheel 17 operates when the front wheels 3 are steered up and down. The chain 12 connected to the chain gear 10 of the front wheel 3 via the guide gears 13 and 14 causes a slight torsional phenomenon. This torsional phenomenon is inevitable during steering operation. In this case, in order to allow sufficient power transmission, it is preferable to employ the chain 12 with a relatively flexible structure.
    On the other hand, on the chain sprocket 7 which is connected to the front and rear wheels 3 and 4 to provide the pedaling force of the pedals 9 and 9 ', the chain sprocket 7 is driven by driving the pedals 9 and 9'. Tension adjusting means 30 and 40 are installed as shown in FIGS. 4A and 4B so that rotational force can be smoothly transmitted to the front and rear wheels 3 and 4.
    First, the chain 12 is connected to the chain sprocket 7 and the rear wheel 4 so that the chain 12 may be connected to the chain gear 11 and the chain sprocket 7 of the rear wheel 4 under tension. The adjustment gear 31 coupled to the 12 is to tension adjustment as the spring 32 and the adjustment nut (33).
    That is, the supporter 34 which engages the adjusting gear 31 on the lower chain 12 of the chain sprocket 7 connected to the chain gear 11 of the rear wheel 4, and the tension gear 31 is built up. The upper side of the spring 32 is elastically supported upward and the spring 32 is elastically coupled to the supporter 34 upper threaded rod 35 is coupled to the adjustment nut 33 as the adjustment nut 33 By adjusting the spring 32 so that the adjustment gear 31 is raised and lowered, the chain 12 of the chain sprocket 7 and the rear wheel 4 are tensioned by pressing downward on the chain 12 connected to the control gear 31. Smooth power transmission is achieved between the chain gears (11).
    In addition, a tension adjusting device 40 is also installed on the chain 12 side where the chain sprocket 7 and the chain gear 10 of the front wheel 3 are connected to the chain 12 side connected to the rear wheel 4. In addition to the tension control device 30 is installed, the chain 12 on the endless track connected to the front and rear wheels (3, 4) to maintain a tension in the upper and lower sides of the chain sprocket (7) to ensure a smooth power transmission As,
    The tension adjusting device 40 on the side of the chain sprocket 7 connected to the front wheel 3 is the upper side of the chain 12 connected to the chain gear 10 of the chain sprocket 7 and the front wheel 3, namely, The chain 12 on the chain sprocket 7 side chain 12, which is connected to the chain gear 10 of the front wheel 3 via the chain sprocket 7 and the steering frame 15, the upper guide gear 13. ) Is installed downward so that the control gear 41 is pushed down, and the lifting rod 42 in which the adjustment gear 41 is built is inserted into a fixed tube 43 fixed on the vehicle body frame 2 to allow the slide lifting operation. The spring 44 is elastically coupled to the inside of the fixing pipe 43 in which the elevating rod 42 is installed, and the adjusting bolt 45 is screwed to the upper end of the fixing pipe 43, according to the tightening degree of the adjusting bolt 45. By adjusting the elasticity of the 44, the degree of tension of the chain 12 which is pushed down on the adjusting gear 41 by the elastic force of the spring 43 is adjusted, The jackets 7 and the tension control between the chain (12) to occur.
    In addition, the chain gears 10 and 11 are connected to the front and rear wheels 3 and 4 connected to the chain sprockets 7 for transmitting the pedaling force of the pedals 9 and 9 'to the front and rear wheels 3 and 4, respectively. Since it is built up, the front and rear wheels 3 and 4, on which the chain gears 10 and 11 are built, are installed on both sides of the rotating shafts 5 and 6 on which the chain gears 10 and 11 are built. In consideration of the overall balance of (1), it is most preferable. If the front and rear chain gears 10 and 11 are installed on both sides of the rotary shafts 5 and 6, in which the front and rear chain gears 10 and 11 are arranged, The front and rear wheels 3 and 4 have a plurality of four wheels, respectively, but the front and rear wheels 3 and 4 must have four wheels with a plurality of front and rear wheels 3 and 4, respectively. If not, if the entire center of the bicycle (1) can maintain the balance, it is natural that it can also be carried out in a two-wheel configuration as conventional.
    In addition, in the present invention, it is very natural that various kinds of shifting means are provided on the front and rear wheels 3 and 4 to enable shifting, and the configuration of such shifting means and the shifting means are provided on the bicycle 1. The mounting structure adopted to allow shifting is also general, and specific implementation thereof is omitted.
    The chain 12 connecting the chain sprocket 7 and the chain gears 10 and 11 of the front and rear wheels 3 and 4 may be replaced by various equivalent means as well as a general chain.
    According to the present invention configured as described above, the driving force of the pedals 9 and 9 'is simultaneously transmitted to the front and rear wheels 3 and 4 so that the bicycle 1 can obtain the driving force by driving the front and rear wheels 3 and 4. When the chain sprocket 7 is rotated by the pedaling force of the pedals 9 and 9 ', the chain gears 10 and 11 of the front and rear wheels 3 and 4 connected to the chain sprocket 7 and the chain 12 are rotated. ), The front and rear wheels 3 and 4, in which the chain gears 10 and 11 are laid, are rotated at the same time to have a strong driving force.
    That is, when the chain sprocket 7 is rotated by the driving of the pedals 9 and 9 ′, the rear wheel 4 is driven by the chain 12 adjusted in a tension state by the chain sprocket 7 and the tension control device 30. The side chain gear 11 rotates, and the rear wheel 4 rotates.
    In addition, since the chain 12 connected to the rear wheel 4 is connected to the front wheel 3 in an endless track, it is again via the chain sprocket 7 and the tension control device 40 so that smooth power transmission is achieved. One chain 12 and the other side chain 12 thereof are connected to the chain gear 10 of the front wheel 3 via the guide gears 13 and 14 below the steering frame 15, so that the chain sprocket 7 The rotational force acts simultaneously on the front and rear wheels 3 and 4 to simultaneously drive the front and rear wheels 3 and 4.
    On the other hand, when the steering wheel 17 is operated while the bicycle 1 is driven by the driving of the front and rear wheels 3 and 4, the steering frame 17 is operated due to the steering wheel 17. 15) will be angularly moved to the front wheel 3, so that the chain 12 connected between the steering wheel 17 lower guide gears 13 and 14 and the chain gear 10 of the front wheel 3 is twisted slightly. This phenomenon will occur, but in this case, since the guide gears 13 and 14 are installed directly below the steering wheel 17 and above the front wheels 3, the guide gears 13 and 14 do not interfere with the angle of the front wheels 3 by the steering operation. will be.
    In addition, each tension control device is installed on the upper and lower sides of the chain sprocket 7 and coupled to the chain 12 to which the chain sprocket 7 and the front and rear wheels 3 and 4 chain gears 10 and 11 are connected. 30, 40 is to facilitate the smooth power transmission by tensioning the connection state of the entire chain 12 around the chain sprocket (7) to provide a smooth running power at all times.
    As described above, the present invention is a practically valuable mountain bike that requires a strong driving force (propulsion force) by pursuing maximization of driving energy by allowing the front and rear wheels 3 and 4 to be driven simultaneously in a relatively simple configuration. In particular, the driving of the front and rear wheels (3, 4) is very excellent, and the driving energy of the bicycle can be promoted very efficiently, and the kinetic energy of the human body As it is delivered directly to achieve a sufficient amount of exercise, the present invention can achieve various advantages and effects in addition to the above.
