According to Fig. 2 to Fig. 5, the bicycle possessing lifting foot pedal of phenomenon is rewinded in utilization according to the present invention, comprising: vehicle frame 100, forms the basic framework of bicycle, is provided with front-wheel, trailing wheel and seat cushion; Major axis crank shaft 200, described vehicle frame is fixed in force, is alternately pressed the external force of stretcher, be elevated, produce power simultaneously with described force for benchmark by rider; Amplifying drive division 300, being connected to the pulley being arranged on described major axis crank the tip of the axis, for amplifying the power produced by rider's externally applied forces; Lifting drive division 400, by making the S. A. being connected to described trailing wheel rotate towards positive dirction at the power of described amplification drive division through amplifying, thus makes bicycle advance; Rewind transformation component 500, while rewinding S. A. by the power making described S. A. rotate in the opposite direction, lift the stretcher of the one end being arranged on described crank shaft, and by backward gear, the opposite spin of described S. A. is transformed to positive dirction rotation, thus bicycle is advanced.
As shown in Figure 2, described vehicle frame 100 forms the basic framework of bicycle, and is fixedly installed trailing wheel, seat cushion and handlebar, is fixed with front-wheel at handlebar, forms the vehicle frame that can maintain the global shape of bicycle thus.
Preferably, near the center shaft being provided with the trailing wheel 110 of lifting drive division of described vehicle frame 100, be combined with plate shape directing plate 150, described force 260 or pulley 310 etc. can be set at described directing plate.
As shown in Figures 2 to 4, described major axis crank shaft 200, comprising: clavate axle 210,220, extends to the rear side of front-wheel from described trailing wheel; Stretcher 230,240, is arranged at described the tip of the axis, and rider applies external force with pin pressing.
Described axle is made up of left axle 210 and right axle 220, left axle 210 with described vehicle frame for benchmark is positioned at the left side of rider, right axle 220 is positioned at the right side of rider, described stretcher is made up of left side stretcher 230 and right side footrest 240, left side stretcher is arranged at described left the tip of the axis, and right side footrest is arranged at described right the tip of the axis.
The directing plate 150 being arranged on described vehicle frame is fixed in the force 260 of described left axle 210 and right axle 220, be formed with clearance line 160 at described directing plate 150, the pulley 310 being connected to described left axle and right axle by the external force of alternately pressing stretcher with described force for benchmark is elevated.
Thus, with in the past by rotate produce power bicycle compared with, power can be produced by means of only the action down pressing described major axis crank shaft 200, the S. A. being arranged at described lifting drive division is made to rewind in the process of original state at the stretcher pressing opposition side, while axle carries out rising, stretcher rises, thus rider can be continuously applied the external force of pressing stretcher.
As mentioned above, correspondingly due to described left axle 210 and right axle 220 non rotating carry out oscilaltion to produce power, therefore, compared with existing position in order to make stretcher come back to again to apply external force and bicycle that crank shaft need rotate completely, unrestricted when forming the length of crank shaft.In the past, the length of described major axis crank shaft 200 only had 160 to 230mm, but the increasing length of crank shaft is added to 600 to 1200mm.
As mentioned above, by increasing the length of crank shaft 200, and make the distance be fixed between the force 260 of directing plate 150 and stretcher 230,240 be longer than the spacing of described force 260 and pulley 310, thus, even if the power putting on described stretcher 230,240 is very little, also described amplification drive division 300 and lifting drive division 400 will can be sent energetically to.
As shown in Figure 2, be formed at described left axle 210 and right axle 220 and formed at predetermined intervals and the length adjustment groove 250 formed by multiple groove, thus, the length combining left side stretcher 230 and right side footrest 240 can be adjusted.
Therefore, when playing more energetically, be formed at the length adjustment groove 150 close to the end of described left axle 210 and right axle 220 in conjunction with stretcher 230,240, thus increase the entire length of major axis crank shaft, when wanting to play little power, be formed at the end length adjustment groove 150 at a distance from described left axle 210 and right axle 220 in conjunction with stretcher to reduce the entire length of major axis crank shaft.
The described major axis crank shaft 200 of formation described above, be that reference connection rises along the clearance line 160 being formed in directing plate by from stretcher 230,240 externally applied forces in the pulley 310 of the other end of described major axis crank shaft to be fixed on the force 260 of directing plate 150, the external force putting on described stretcher passed to simultaneously and amplify drive division and lifting drive division.
Described amplification drive division 300, comprising: one, with top sheave 310, is incorporated into the other end of described major axis crank shaft 200; Fixing drum 330, is fixed on the S. A. be connected with the center shaft of trailing wheel, and rotates together with described S. A.; Power transfering part 320, by described pulley is elevated transmission of power give described fixing drum.
As shown in Figures 7 and 8, described pulley 310 is interconnected with the fixed link 312 of top sheave by being jointly connected to one, and the lifting along with described major axis crank shaft 200 is moved together.
Described power transfering part 320 is preferably made up of steel cable or chain etc., and described power transfering part is arranged via described pulley 310 and fixing drum 330, thus, fixing drum 330 can be made to rotate with the lifting of top sheave 310 along with described one.
Now, by the power transfering part 320 of described steel cable or chain etc., the bracket 322 arranged on described directing plate 150 is fixed in one end, the other end is fixed on fixing drum 330, along with the lifting of described pulley, when distance between pulley 310 and fixing drum 330 becomes far away, fixing drum 330 can be made to rotate and produce rotary power.
Namely, form the steel cable of described power transfering part 320 or chain and can't help external force and stretch, therefore, when when described pulley 310 rises, distance between pulley and fixing drum is outlying, described steel cable 320 or chain are drawn, and make fixing drum 330 rotate, by the rotation of described fixing drum simultaneously, S. A. 410 also together rotates, and produces the rotational force of pivoting rear wheel.
The quantity of the described pulley of preferred correspondence 310 forms described fixing drum 330, and as illustrated in the schematic views of figures 7 and 8, when described pulley 310 is towards when being horizontally arranged with 2, described fixing drum 330 is also towards horizontally set 2.
In order to increase the displacement produced by externally applied forces during rider's step pedal, described amplification drive division 300 adjusts wiring ratio by increasing and decreasing the quantity of described pulley 310 and fixing drum 330, thus amplifies or lower the power passing to S. A..
As illustrated in the schematic views of figures 7 and 8, pulley 310 and fixing drum 330 are respectively arranged with 2, at each pulley 310 by connecting each fixing drum 330 respectively by the power transfering part 320 of steel cable or chain etc., thus, whenever 2 pulleys 310 rise one time time, the steel cable 320 be interconnected between pulley and fixing drum extends, and displacement is increased to 4 times, thus, the degree of rotation of S. A. can more be increased.
Namely, as shown in Figure 9, when described amplification drive division 300 is made up of a pulley 310 and a fixing drum 330, if pulley 310 rises and distance between pulley and fixing drum is outlying, then the displacement of the power transfering parts 320 such as the steel cable produced due to the movement of described pulley or chain all occur in from the distance of one end to pulley of being fixed on bracket and from described pulley to the distance of fixing drum.
When the miles of relative movement of described pulley is set to 1, the displacement produced at power transfering part is 2, therefore, is passed to S. A. on the whole with the wiring of 2:1 than by rotational force, thus, by the power that puts on stretcher with the state transfer of more amplifying than the power passing to pulley to S. A..
And, as illustrated in the schematic views of figures 7 and 8, when pulley 310 and fixing drum 330 are formed by 2 respectively, if pulley rises and distance between pulley and fixing drum separates, then from the distance of one end to the first pulley of being fixed on bracket, from the first pulley to the distance of the first fixing drum, from the first fixing drum to the distance of the second pulley and the displacement that steel cable or chain all occur from the second pulley to the distance of the second fixing drum.
Foot-operated will be arranged at the stretcher of one end of described major axis crank shaft and the distance of two pulley movements that produces when being set to 1 respectively, total miles of relative movement of the pulley directly produced when stepping on a stretcher becomes 2, but become 4 in the net slip that power transfering part produces at 2 fixing drums, therefore, on the whole with the wiring of 4:2 than rotational force is passed to S. A..
Equally, as shown in Figure 10, when pulley 310 and fixing drum 330 are formed by 3 respectively, S. A. is passed to than by rotational force on the whole with the wiring of 6:3, as shown in figure 11, when pulley 310 and fixing drum 330 are formed by 4, on the whole with the wiring of 8:4 than rotational force is passed to S. A..
Therefore, described pulley 310 is provided with n (n is natural number) towards transverse direction, described fixing drum 330 is arranged at the bottom of described pulley towards transverse direction, be provided with n, along with described n pulley rises, the displacement produced at power transfering part becomes 2n doubly, and pass to S. A. after amplifying power with the winding ratio of 2n:n, therefore, when only pressing a stretcher, also the displacement forming the steel cable of power transfering part or chain etc. can be strengthened, thus, the rotational force being passed to S. A. can be increased.Namely increase the rotation number of S. A. by once rolling of stretcher, and can obtain and rotate faster.Make by once rotating, fixing drum can rotate repeatedly, and the total length of the power transfering part be made up of described steel cable or chain etc. needs elongated.
As illustrated in the schematic views of figures 7 and 8, described lifting drive division 400, comprising: S. A. 410, is fixed with described fixing drum 330, together rotates with the fixing drum 330 being undertaken rotating by the displacement produced at power transfering part 320; General gear 420, is connected to the center shaft of described trailing wheel, and is connected to described S. A. by bearing, receives rotational force and trailing wheel is rotated; Sprocket wheel 430, is connected to described S. A., adjusts in the mode producing power while only rotating towards a direction.
Now, described general gear 420 is gears that the rotational force of S. A. 410 by carrying out positive dirction rotation makes trailing wheel advance, the mode that described general gear is meshed with multiple wheel word combines, by the rotational force of the S. A. transmitted by described bearing be meshed rotate while, the center shaft of trailing wheel is rotated, described general gear is identical with normally used gear, therefore, and detailed.
Preferably, the S. A. 410 in the left side and right side that are formed at described trailing wheel 110 runs through the center shaft of described trailing wheel and is interconnected, and described S. A. is rotated together along the hand of rotation of described fixing drum 330.
As mentioned above, by being formed in the mode that the S. A. 410 in the left side and right side that are formed at trailing wheel is rotated together towards the hand of rotation of fixing drum, be pressed according to major axis crank shaft 200, repeatedly towards positive dirction and opposite spin, thus, not apply external force, the axle of the side namely do not pressed by rider rises.Now, in order to prevent the rotational force of the S. A. occurred in the side not applying described external force from passing to trailing wheel, trailing wheel being rotated, possessing sprocket wheel 430 in the front end of bearing 440.
Describedly rewind power transfering part 320 that transformation component 500 is configured to be made up of described steel cable or chain and be wound in described fixing drum 330 in the opposite direction and make when alternately pressing described stretcher 230,240, S. A. 410 is positive dirction and opposite spin repeatedly, comprise backward gear 500 further, be connected with the center shaft of trailing wheel, be arranged at the side of described trailing wheel 110, receive after carrying out the rotational force of the S. A. 410 of opposite spin and be transformed to positive dirction rotation, and be passed to bearing 440.
Now, backward gear 500 causes the side of opposite spin when being and being arranged at pressing stretcher, and the opposite spin of S. A. 410 is transformed to the positive dirction rotation that bicycle can be made to advance, thus the gear that trailing wheel is advanced, the mode that described backward gear is meshed with multiple wheel word combines, and combines with the center shaft of described trailing wheel.Described backward gear is not limited to particular types, can use the backward gear opposite spin of S. A. being transformed to the various forms that positive dirction rotates.
As mentioned above, when being fixed on the fixing drum winding power transfering part 320 such as steel cable or chain of S. A. 410, coiling direction is mutually contrary, pulley 310 is rotated by the rolling of stretcher and rises, and during motive force transfer part, fixing drum 330 is mutually contrary with S. A. 410 hand of rotation, thus, when pressing left side stretcher 230, while S. A. 410 carries out positive dirction rotation, right side footrest 240 rises, and when pressing right side footrest 240, S. A. 410 carries out opposite spin and while getting back to original position, left side stretcher 230 rises again, thus rider alternately can press stretcher.
As shown in Figure 6, S. A. 410 in specialized range repeatedly positive dirction rotate and opposite spin keep original position, but, the rotational force produced when positive dirction rotation and opposite spin can be used in the advance of trailing wheel by general gear 420 and backward gear 500, therefore, not only crank shaft is formed as longer, and, bicycle stably advancing drive can be made.
Figure 12 is the constructional drawing of other embodiments illustrated according to amplification drive division of the present invention.
With reference to Figure 12, described amplification drive division, comprising: linear gear 610, is elevated by pressing each stretcher; Circular gear 620, between described each linear gear, and is meshed with described each linear gear, makes the straight-line motion of the lifting by described linear gear be converted to rotary motion; Adapter shaft 630, connects the mutual of described circular gear.
Described linear gear 610 is connected to and forms the left axle of major axis crank shaft and each rearward end of right axle, when pressing left side stretcher, while the linear gear 610 in left side being arranged at the left side of trailing wheel rises centered by force, left side circular gear 620 is rotated, make the center shaft of the trailing wheel being connected to left side circular gear 620 rotate thereupon, when pressing right side footrest, while the linear gear 610 in right side being arranged at the right side of trailing wheel rises centered by force, right side circular gear 620 is rotated, the center shaft of the trailing wheel then making gear 610 linear with right side be connected rotates.
Now, the rotation of described left side circular gear 620 makes S. A. 630 positive dirction rotate, therefore, by the general gear forming lifting drive division, trailing wheel is advanced, the rotation of described right side circular gear 620 makes adapter shaft 630 opposite spin, by the backward gear forming described lifting unit, trailing wheel is advanced, thus bicycle advance by the power pressing stretcher.
The advance of trailing wheel when described adapter shaft 630 positive dirction rotates and the advancing drive of trailing wheel during opposite spin with utilize above-mentioned steel cable or chain that adapter shaft 630 positive dirction is rotated or opposite spin time identical, therefore, detailed.
As mentioned above, described amplification drive division, comprising: linear gear 610, is elevated by moving up and down of major axis crank shaft; Circular gear 620, is meshed with described linear gear and produces rotary motion; And adapter shaft 630, be interconnected between described circular gear, rotate by the rotational force produced at circular gear, also be interconnected when described amplification drive division is formed as mentioned above, the adapter shaft 630 of positive dirction rotation and opposite spin is carried out by alternate repetition, when pressing side stretcher, opposite side stretcher rises, thus rider can continuous drive stretcher.
As shown in figure 12, the top of described linear gear 610 is connected to rider by being applied the end of the major axis crank shaft 200 of external force by the power transfering part 320 of steel cable or chain etc., described power transfering part is formed in the mode of top sheave 310 and fixing drum 330 to reel one, thus, as mentioned above, the displacement produced by rider's externally applied forces can be increased.Now, by increasing the quantity of described pulley and fixing drum, increase the displacement of linear gear, thus, with once driving and can producing larger power, this is identical with the situation of above-mentioned amplification drive division, therefore detailed.
Unlike this, also can form as follows, namely directly connect described linear gear at the other end of described major axis crank shaft 200, described linear gear is directly risen by the power of step pedal, and produces the displacement that trailing wheel is rotated.
Below illustrate that the utilization of the present invention formed as mentioned above is rewinded phenomenon and possesses the effect of the bicycle of lifting foot pedal.
When rider's pressing is arranged at the left side stretcher 230 of one end of the major axis crank shaft 200 of more than length 600mm, to be fixed on the force 260 of directing plate 150 for benchmark, the pulley 310 being arranged at the other end of major axis crank shaft rises mobile.Now, rider applies the left side stretcher 230 of power, is positioned at the position away from pulley when major axis crank shaft being benchmark with force, and therefore, the principle of general lever, even if apply little power, also can embody energetically in pulley 310 side.
One is horizontally arranged with top sheave 310 in the other end court of described major axis crank shaft, directing plate 150 and fixing drum 330 are fixed in the two ends of each pulley 310, owing to pulley being wound with the power transfering part 320 such as steel cable or chain with specified length, therefore, the power transfering parts such as steel cable 320 are pulled to top along with the rising of pulley 310, make fixing drum 330 rotate simultaneously.
Now, described pulley 310 and fixing drum 330 mutually correspondence are provided with multiple, are connected, therefore between described pulley and fixing drum by steel cable 320 etc., according to set pulley and fixing quantity of rousing, the power transfering parts such as steel cable 320 are drawn with the wiring of 2:1,4:2,6:3 or 8:4 ratio, thus, only step on the net slip that a time stretcher also can be increased in power transfering part generation, therefore, larger rotational force can be obtained.
As mentioned above, rotational force for rotating fixing drum 330 makes the S. A. 410 being fixed with fixing drum rotate, the rotation of described S. A. 410, and the general gear 420 making to be connected to the center shaft of trailing wheel by the bearing 440 be connected with S. A. rotates, thus, trailing wheel can be driven to advance.
The power transfering parts such as described steel cable 320 be arranged on described trailing wheel left side fixing drum on coiling direction opposite sense be wound in be arranged on right side fixing drum, when described S. A. 410 along with the decline of described left side stretcher 230 carry out positive dirction rotate time, while the fixing drum being arranged at right side reels the power transfering parts such as steel cable, distance between pulley and fixing drum reduces, thus the right side footrest 240 being arranged at the front end of major axis crank shaft rises.
Then, if rider presses right side footrest 240, then with force 260 for benchmark, the pulley 310 being arranged at the other end of major axis crank shaft rises mobile.Now, the right side footrest 240 that rider applies power is also the position that benchmark is in away from pulley with force on major axis crank shaft, therefore, can realize larger power in pulley side.
Thus, if while the pulley 310 being arranged at the right side of described trailing wheel rises, toward the power transfering part 320 such as pull-up steel cable, then the power transfering part 320 that fixing drum 330 is fixed in one end is drawn, and fixes drum 330 thus and rotates.Now, the coiling direction being arranged at the power transfering part 320 on the right side of described trailing wheel is contrary with the coiling direction of the power transfering part in the left side being arranged at trailing wheel, and therefore, fixing drum 330 carries out opposite spin, with this, the S. A. 410 being fixed with fixing drum also carries out opposite spin.
By the S. A. 410 of opposite spin described above, while the power transfering parts such as steel cable 320 are wound in the fixing drum 330 in the left side being arranged on trailing wheel, the distance between pulley and fixing drum shortens, thus left side stretcher 230 rises.
The opposite spin of the S. A. 410 produced when pressing described right side footrest 240 is transformed to the center shaft being transferred to trailing wheel after positive dirction rotates by the backward gear 500 being arranged at the right side of described trailing wheel, thus can make trailing wheel advancing drive.
So, positive dirction by S. A. rotates and opposite spin, while left side stretcher 230 and right side footrest 240 are alternately elevated, rider can apply external force continuously, and the opposite spin of S. A. 410 is not only used in the rising of stretcher, and, carry out advancing drive by backward gear 500, therefore, can lower and be lost to outside power, and, can advancing drive be realized.
The present invention can realize in the past because the problem of the structure of bicycle is difficult to the problem of the crank shaft forming more than length 600mm, therefore, the principle of lever is more positively applicable to the driving of bicycle, also can produces more rotational force with few power, thus can easily realize running at high speed.
Apply the distance between the stretcher of power and force due to rider and produced the difference of the distance between the pulley of the power that bicycle is advanced and force by pedal force large, thus occur to conjugate the problem reduced, now, by towards transverse direction arrangement and winding one compensates reducing of displacement with the displacement increase of the power transfering parts such as the steel cable of top sheave and fixing drum, thus, being lost of power when can lower rider's step pedal by bike, can run at high speed simultaneously.
Above, with reference to the accompanying drawings of technological thought of the present invention, but these are casehistory the preferred embodiments of the present invention, do not limit the present invention.And, concerning carrying out various distortion those skilled in the art in the invention within the scope of technological thought of the present invention and imitation is self-evident.
