Abstract
A folding bicycle includes a folding mechanism that permits the folding bicycle in its extended state to be folded at an intermediate region between a front wheel and a rear wheel. The folding bicycle is folded by the folding mechanism such that the front wheel is brought to a position at one side of the rear wheel. An axle shift mechanism permits a axle of the rear wheel to be shifted to a position toward the intermediate region. A chain-holding mechanism holds a sprocket chain at a predetermined position when the axle is shifted to the position toward the intermediate region by the axle shift mechanism, to thereby release engagement between a rear wheel-side sprocket and the sprocket chain.
Description
- 1. Field of the Invention
- This invention relates to a folding bicycle constructed in a manner foldable about a central portion of a body thereof.
- 2. Description of the Related Art
- A
bicycle 71 shown in FIG. 12 is among folding bicycles of the above-mentioned type as the related art. Thebicycle 71 includes aframe 74 rotatably supporting afront wheel 2 and arear wheel 3, adrive mechanism 6 for driving thebicycle 71, arack 75 secured above therear wheel 3, asteering section 77 linked to thefront wheel 2, aseat section 8 secured to a central portion of theframe 74, and akick stand 79 that allows thebicycle 71 in its extended state to stand by itself and is capable of supporting thebicycle 71 in its folded state. Theframe 74 is comprised of afront fork 11 connected to thesteering section 77 and having thefront wheel 2 secured thereto via anaxle 2 a, asteering head 12 holding thefront fork 11 and thesteering section 77 in a rotatable manner, adown tube 13, afolding mechanism 14 for folding thebicycle 71, arear arm 85 connected to thedown tube 13 via thefolding mechanism 14 and having therear wheel 3 secured thereto via anaxle 3 a, aseat tube 86 extending upward from therear arm 85, for having theseat section 8 secured thereto such that theseat section 8 can be moved vertically, a seat stay 87 connecting between the rear end portion of therear arm 85 and the upper end portion of theseat tube 86, and astay 88 having therack 75 secured thereto. - The
drive mechanism 6 includes a pedal-side sprocket 33 to which are attachedpedals respective cranks side sprocket 35 which is rotated via asprocket chain 34 as the pedal-side sprocket 33 rotates. Thesteering section 77 is comprised of astem 95 connected to an upper end of thefront fork 11 within thesteering head 12 and ahandle bar 96 secured to the upper end of thestem 95. Further, theseat section 8 is comprised of aseat post 51 secured to theseat tube 86 such that theseat post 51 can be moved vertically therein, and asaddle 53 secured to the upper end of theseat post 51 via a saddle angle-adjusting mechanism 52. - The
bicycle 71 is folded through the following procedure. First, as shown in FIG. 13, theseat post 51 is pushed down into theseat tube 86 such that it is received therein. Then, after thehandle bar 96 is turned downward to a position where each of the opposite ends thereof looks as if suspended from the upper end of thestem 95, thesteering section 77 in this state and thefront fork 11 having thefront wheel 2 secured thereto are turned around. At this time, thefront wheel 2 is shifted toward thefolding mechanism 14 by a distance which is twice longer than a front fork offset. Subsequently, thebicycle 71 in this state is folded by and about thefolding mechanism 14 at the central portion of thebicycle 71. As a result, thefront wheel 2 is positioned at the left side of the rear wheel 3 (as viewed from the rear of the bicycle 71), whereby the length of thebicycle 71 is reduced approximately by half in comparison with the whole length of thebicycle 71 in its extended state. Thereafter, by placing the front andrear wheels kick stand 79 on the ground, with thekick stand 79 kicked backward as shown in FIG. 14, thebicycle 71 in its folded state stands in a state supported by the front andrear wheels kick stand 79. - However, the
above bicycle 71 suffers from the following problems: As described above, thebicycle 71 is folded by and about thefolding mechanism 14 at the central portion of thebicycle 71, so that the length of thebicycle 71 is reduced approximately by half in comparison with the whole length of thebicycle 71 in its extended state. However, the distance from theaxle 2 a to thefolding mechanism 14 and the distance from theaxle 3 a to thefolding mechanism 14 are each longer than the radius of thefront wheel 2 and that of therear wheel 3, and hence thedown tube 13 and therear arm 85 project considerably far from the front andrear wheels bicycle 71. If the distance between the twoaxles respective axles 2 a 3 a and thefolding mechanism 14, running stability of thebicycle 71 is degraded due to the reduction of the distance between theaxles axles respective wheels folding mechanism 14 in the folded state while maintaining the running stability of thebicycle 71 in the extended state, reduction of the size of thebicycle 71 in its folded state (hereinafter also referred to as “the foldedbicycle 71”) is difficult. - Another problem occurs with the folded
bicycle 71 when it is carried. If a user tries to move the foldedbicycle 71 by rotating thewheels rear wheel 3 causes rotation of the rear wheel-side sprocket 35, whereby the pedal-side sprocket 33 is rotated via thesprocket chain 34. As a result, thepedal 32 attached to thecrank 91 a is brought into abutment with thefront wheel 2 or thedown tube 13. This abutment inhibits the rotation of the rear wheel-side sprocket 35, and hence it becomes impossible to rotate therear wheel 3. Consequently, the user has to carry the foldedbicycle 71 e.g. by holding theseat tube 86 by hand and lifting thewhole bicycle 71. - Still another problem is as follows: In the
bicycle 71, thehandle bar 96 is turned with respect to thestem 95 for reduction of the size of thebicycle 71 in its folded state. However, even when thehandle bar 96 is turned downward, the length from thesteering head 12 to the upper end of thestem 95 is not reduced, and, what is more, the opposite ends of thehandle bar 96 largely project leftward and rightward, respectively, from the foldedbicycle 71. This also makes it difficult to reduce the size of thebicycle 71 in its folded state. Further, thepedals bicycle 71, which also makes it difficult to reduce the size of the foldedbicycle 71. - Moreover, as shown in FIG. 15, when the
bicycle 71 is folded, thefront wheel 2 and therear wheel 3 are not in a state held in parallel with each other. Therefore, in moving forward or backward the foldedbicycle 71 with thewheels rear wheels bicycle 71 straight in the direction of reverse rotation of therear wheel 3 e.g. by pushing theseat tube 86, the resistance to rotation of thefront wheel 2 is increased, which makes it difficult to carry thebicycle 71 in a state of thewheels - In addition, there is another problem that when the
bicycle 71 is folded, the user has to carry baggage which was placed on therack 75 during running of thebicycle 71, apart from thebicycle 71. More specifically, in the state of thebicycle 71 being folded, therack 75 is inclined at a large angle with respect to the ground GL as shown in FIG. 14, so that if the baggage is left on therack 75, the baggage can fall off therack 75 due to its own weight. Therefore, it is hard to carry thebicycle 71 with the baggage placed on therack 75, and hence the user has to carry thebicycle 71 by one hand while carrying the baggage by the other hand, which is very troublesome and laborious. - It is an object of the invention to provide a folding bicycle that is reduced in size in its folded state while maintaining the running stability in its extended state and easy to carry in its folded state.
- It is another object of the invention to provide a folding bicycle that can be carried with baggage loaded thereon.
- To attain the above objects, the present invention provides a folding bicycle including a front wheel, a rear wheel having an axle, a rear wheel-side sprocket connected to the rear wheel, a sprocket chain for being engaged with the rear wheel-side sprocket, and a folding mechanism permitting the folding bicycle in an extended state to be folded at an intermediate region between the front wheel and the rear wheel, wherein the folding bicycle is folded by the folding mechanism such that the front wheel is brought to a position at one side of the rear wheel.
- The folding bicycle according to the invention is characterized by comprising an axle shift mechanism permitting the axle of the rear wheel to be shifted to a position toward the intermediate region, and a chain-holding mechanism that holds the sprocket chain at a predetermined position when the axle is shifted to the position toward the intermediate region by the axle shift mechanism, to thereby release engagement between the rear wheel-side sprocket and the sprocket chain.
- According to this folding bicycle, since the bicycle is provided with the axle shift mechanism that permits an axle of the rear wheel to be shifted toward the intermediate region, it is possible to increase the distance between the two axles in the extended state of the bicycle, thereby securing the running stability of the bicycle, and at the same time it is possible to reduce the distance between the two axles in the folded state of the bicycle, thereby reducing the size of the folded bicycle. Further, in the folded state of the bicycle, the chain-holding mechanism holds the sprocket chain at the predetermined position when the axle is shifted toward the intermediate region by the axle shift mechanism, thereby releasing engagement between the rear wheel-side sprocket and the sprocket chain, so that it is possible to prevent the rear wheel-side sprocket from being rotated with rotation of the rear wheel, thereby allowing the folding bicycle to be moved by rotation of the wheels.
- Preferably, the folding bicycle includes a front wheel-securing mechanism that rotatably secures the front wheel in a folded state of the folding bicycle, such that lines of intersection where a plane of rotation of the front wheel defined as an imaginary geometrical plane which contains a diameter of the front wheel and to which a rotational axis of the front wheel is perpendicular, and a plane of rotation of the rear wheel defined as an imaginary geometrical plane which contains a diameter of the rear wheel and to which a rotational axis of the rear wheel is perpendicular intersect with a ground plane defined as an imaginary geometrical plane corresponding to an arbitrary surface on which the front wheel and the rear wheel are supported are substantially parallel to each other.
- According to this preferred embodiment, the front wheel-securing mechanism rotatably secures the front wheel in the folded state of the bicycle, such that lines of intersection where planes of rotation of the respective front and rear wheels intersect with the ground plane are substantially parallel to each other, so that when the folding bicycle in the folded state is moved by rotation of the wheels, the front and rear wheels rotate smoothly, thereby making it easy to move the folding bicycle.
- Preferably, the folding bicycle includes an auxiliary wheel arranged in the vicinity of the folding mechanism such that the auxiliary wheel can be placed on a ground together with the front wheel and the rear wheel in the folded state of the folding bicycle, a rack arranged above the rear wheel, and a rack retainer mechanism that holds the rack generally horizontal with respect to a ground plane on which the front and rear wheels are placed, both in the extended state and in a folded state of the folding bicycle.
- According to this preferred embodiment, by holding the rack horizontal by means of the rack retainer mechanism, it is possible to move the bicycle in the folded state with baggage placed on the rack by rotation of the front and rear wheels and the auxiliary wheel. Thus, the bicycle in the folded state can be used as a cart.
- Preferably, the folding bicycle includes a kick stand arranged in the vicinity of the folding mechanism such that the kick stand can support the folding bicycle in a folded state thereof when the kick stand is in a predetermined position, and a seat post, and when the front wheel, the rear wheel, and the kick stand are placed on a ground in the folded state of the folding bicycle, the seat post is generally perpendicular to a plane of the ground.
- According to this preferred embodiment, when the bicycle in the folded state is supported by the kick stand, the seat post is generally perpendicular to the ground plane, so that simply by adjusting a saddle such that it is held in a horizontal position with respect to the ground plane, it is possible to use the folded bicycle as a chair.
- Preferably, the folding bicycle includes a pair of pedals, a pair of pedal cranks connected to the pedals, respectively, one of the pair of pedals projecting from a corresponding one of the pair of pedal cranks in a direction away from the one side of the rear wheel in a folded state of the folding bicycle, and a crank-turning mechanism that permits the one of the pair of pedal cranks to be turned in a manner such that the one of the pair of pedals projects toward the one side of the rear wheel.
- According to this preferred embodiment, the crank-turning mechanism makes it possible to turn one of the pedal cranks such that the left and right pedals project in the same direction. Therefore, it is possible to reduce the width of the bicycle in the folded state, whereby the size of the folding bicycle can be further reduced in its folded state.
- Preferably, the folding bicycle includes a handle system having a telescopic column portion, and an extended portion connected to an upper end of the telescopic column portion such that the extended portion can be fixed at a desired stem angle and that the extended portion can be rotated about an axis extending in a direction of extension of the extended portion.
- According to this preferred embodiment, the bicycle is provided with the telescopically and rotatable handle system. Therefore, it is possible to make the bicycle in its folded state more compact, whereby the size of the folding bicycle can be reduced in its folded state.

In the following description of a folding bicycle according to the preferred embodiment, component parts and elements similar to those of the
bicycle 71 according to the related art described hereinbefore are designated by identical reference numerals, and detailed description thereof is omitted. - Referring first to FIG. 1, there is shown the
folding bicycle 1 which is comprised of afront wheel 2, arear wheel 3, aframe 4, arack 5, adrive mechanism 6, asteering section 7, aseat section 8, and akick stand 9. Thefront wheel 2 and therear wheel 3 are secured to theframe 4 viarespective axles frame 4. Theframe 4 is comprised of afront fork 11, asteering head 12, adown tube 13, afolding mechanism 14, arear arm 15, and aseat tube 16. Thefront fork 11 has thefront wheel 2 secured thereto via theaxle 2 a and has an upper end thereof connected to thesteering section 7. Further, thefront fork 11 has afender 21 secured thereto. Attached to thefender 21 is alocking mechanism 22 corresponding to a front wheel-securing mechanism of the invention. Thelocking mechanism 22 is brought into engagement with therack 5 when thebicycle 1 is folded, to thereby rotatably secure thefront wheel 2 to a side of therear wheel 3, such that lines of intersection where planes of rotation of the respective front andrear wheels head 12 is fixedly attached to one end of thedown tube 13, for rotatably supporting thefront fork 11 and thesteering section 7. Thefolding mechanism 14 foldably connects thedown tube 13 and therear arm 15 to each other. - The
rear arm 15 is formed to have a V shape as viewed from above. Theseat tube 16 has a lower end portion thereof fixed to a narrow-width portion of therear arm 15 in a manner sandwiched by the forks of therear arm 15, while therear wheel 3 is fitted in a wide-width portion of therear arm 15 via theaxle 3 a. Therear arm 15 is formed with a pair of slits 24 (through the respective forks) for receiving therear axle 3 a therethrough. Theslits 24 allow therear axle 3 a to be shifted from a position shown in FIG. 2A, where it is fixed during running of thebicycle 1, to a position shown in FIG. 2B, where it is fixed when thebicycle 1 is folded. In this embodiment, theslits 24 and theaxle 3 a form an axle shift mechanism of the invention. Further, as shown in FIG. 1, therear arm 15 is integrally formed with a pair ofstays 15 a each extending upward from above a corresponding one of theslits 24, for supporting therack 5 in a pivotally movable manner, and theseat tube 16 has astay 15 b joined to a lower end thereof in a manner projecting downward, for having thekick stand 9 attached thereto. Further, mounted to a lower portion of therear arm 15 close to thefolding mechanism 14 is anauxiliary wheel 17. Theseat tube 16 has astay 16 a joined thereto for having therack 5 connected to thestay 16 a, and ametal fixture 60 mounted thereto for fixing theseat section 8, and is fixedly secured to therear arm 15, as described above. As shown in FIG. 3, thestay 16 a has an end portion to which is attached ametal hook 25 corresponding to a rack retainer mechanism of the invention. Themetal hook 25 is bolted to thestay 16 a in a manner pivotally movable about apivot 25 a. Themetal hook 25 cooperates with thestay 16 a to maintain therack 5 in a generally horizontal position with respect to the ground plane on which the front andrear wheels bicycle 1 and in the folded state of the same. - As shown in FIGS. 2A, 2B, the
rack 5 is comprised ofplates 5 a located at the respective opposite sides of therear wheel 3 and formed with through holes, respectively, through which theaxle 3 a extends, acarrier portion 5 d secured to theplates 5 a via pairs ofstays portions 5 e for connecting therack 5 to thestays 15 a of therear arm 15 in a rotatable manner, andcrossbars rack 5 in a state caught between thestay 16 a of theseat tube 16 and themetal hook 25. When thecrossbar 5 f is caught between thestay 16 a and themetal hook 25 as shown in FIG. 2A, theaxle 3 a is shifted to the rear ends of therespective slits 24 of therear arm 15. As a result, the distance between theaxle 3 a and thefolding mechanism 14, i.e. the distance between theaxles bicycle 1 is maintained. On the other hand, when therack 5 is rotated about the connectingportions 5 e in the direction indicated by an arrow A in FIG. 2A until thecrossbar 5 g is caught between thestay 16 a and themetal hook 25 as shown in FIG. 2B, theaxle 3 a is shifted to the front ends of therespective slits 24. As a result, the distance between theaxle 3 a and thefolding mechanism 14 is shortened, whereby the total length of thebicycle 1 in the folded state is reduced. Further, in thebicycle 1, in the state of thecrossbar stay 16 a and themetal hook 25 as shown in FIG. 2A or 2B, thestay 5 c functions similarly to the seat stay 87 of theframe 74 of thebicycle 71. - As shown in FIG. 1, the
drive mechanism 6 is comprised ofcranks bicycle 1 and havingpedals 32 attached to respective ends thereof, a pedal-side sprocket 33 having thecranks side sprocket 35 connected to therear wheel 3, for being driven for rotation via thesprocket chain 34. The rear wheel-side sprocket 35 is secured to therear wheel 3 by a so-called free mechanism for transmitting only torque applied via thesprocket chain 34 to drive thebicycle 1 forward, to therear wheel 3. As shown in FIGS. 4A, 4B, the crank 31 b is connected to the pedal-side sprocket 33 in a state fixed to abase member 37 by fixingbolts bolts base member 37 cooperatively constitute a crank-folding mechanism of the invention. When thebicycle 1 is extended, the crank 31 b is shifted to a position indicated by dotted lines in FIG. 4A. On the other hand, in folding thebicycle 1, the crank 31 b is pivotally moved about the fixingbolt 38 a in the direction indicated by an arrow B in the figure. In this state, the pedal 32 attached to the crank 31 a and the pedal 32 attached to the crank 31 b project in the same direction, whereby the size of thebicycle 1 in its folded state (hereinafter also referred to as “the foldedbicycle 1”) is reduced. - As shown in FIGS. 5A, 5B, arranged in the vicinity of the rear wheel-
side sprocket 35 is a chain-holdingmechanism 27 for releasing engagement between the rear wheel-side sprocket 35 and thesprocket chain 34 by holding thesprocket chain 34 at a predetermined position when thebicycle 1 is folded. The chain-holdingmechanism 27 includes anarm 28 which has apulley 28 a attached to an end thereof and is connected to one of theplates 5 a of therack 5 in a manner pivotally movable about apivot 28 b, and anarm 29 which has apulley 29 a attached to an end thereof and is connected to the one of theplates 5 a in a manner pivotally movable about apivot 29 b. In the chain-holdingmechanism 27, when theaxle 3 a is shifted to the rear ends of theslits 24 as shown in 5A, thepulleys sprocket chain 34. On the other hand, when theaxle 3 a is shifted to the front ends of theslits 24, thearms respective pins rear arm 15 and loosely fitted throughgrooves 28 d, 29 d formed in thearms arms respective pivots side sprocket 35 shifted together with theaxle 3 a is disengaged from thesprocket chain 34 by thepulleys sprocket chain 34 by the above motion, and thesprocket chain 34 is held in engagement with thepulleys side sprocket 33. - Referring again to FIG. 1, the
steering section 7 is comprised of astem 44 having its lower end connected to thefront fork 11 within the steeringhead 12 and a drop bar-type handle bar 45 secured to thestem 44. As shown in FIG. 6A, thestem 44 is comprised of anundertube 41, anupper post 42, and anextension beam 43. Theundertube 41, which cooperates with theupper post 42 to form a column portion of the invention, is comprised ofpipes folding mechanism 41 b. Theupper post 42 is held by theundertube 41 in a vertically movable manner. Theextension beam 43 corresponding to an extended portion of the invention is secured to theupper post 42 such that the stem angle of theextension beam 43 with respect to theupper post 42 can be set as desired. Theextension beam 43 is comprised of abase portion 43 a, alower metal retainer 43 b, anupper metal retainer 43 c, and ashaft 43 d extending from thebase portion 43 a. Theupper metal retainer 43 c is bolted to thelower metal retainer 43 b, whereby thehandle bar 45 is fixedly held between the twometal retainers extension beam 43 is constructed, as shown in FIG. 6B, such that when a fixingbolt 43 e for tightening the lower andupper metal retainers metal retainers base portion 43 a in directions indicated by a double-headed arrow D in the figure, and in this state thehandle bar 45 is held between the twometal retainers handle bar 45 can be rotated about theshaft 43 d. - Next, the method of using the
bicycle 1 will be described with reference to FIGS. 1, 6B, and 7 to 11. - This
bicycle 1 is capable of being placed in the extended state for running, as shown FIG. 1, in a first folded state for use as a cart, as shown in FIG. 8, or in a second folded state for storage, as shown in FIG. 10. - First, for running, each part or section of the folded
bicycle 1 is extended, and then thekick stand 9 is kicked backward off the ground GL, whereby thefront wheel 2 and therear wheel 3 are brought into contact with the ground GL. In this state, since theaxle 3 a of therear wheel 3 is positioned at the rear ends of theslits 24, there is maintained a sufficient distance between the twoaxles bicycle 1. - On the other hand, to fold the
folding bicycle 1 into the first folded state for use as a cart, first, as shown in FIG. 7, therack 5 is pivotally moved about the connectingportions 5 e to shift theaxle 3 a to the front ends of theslits 24 and place thecrossbar 5 g in the state caught between thestay 16 a and themetal hook 25. In this state, the distance between theaxle 3 a and thefolding mechanism 14 is shorter than when thebicycle 1 is in its extended state. Further, the chain-holdingmechanism 27 holds thesprocket chain 34 at the predetermined position to thereby release engagement between the rear wheel-side sprocket 35 and thesprocket chain 34, so that thedrive mechanism 6 is inhibited from being driven for rotation with rotation of therear wheel 3. Then, theseat section 8 is pushed into theseat tube 16 while rotating theseat section 8 until theseat post 51 is received in theseat tube 16. Next, the crank 31 b is rotated about the fixingbolt 38 a. At this time, thepedal 32 on the crank 31 b which projected rightward as viewed from the rear of thebicycle 1 is caused to project leftward, i.e. in the direction in which thepedal 32 on thecrank 31 a projects. Then, thefront wheel 2, thefront fork 11, and thesteering section 7 are all turned around. At this time, the distance between theaxle 2 a and thefolding mechanism 14 is reduced by a distance which is twice as long as a front fork offset, compared with that in the extended state of thebicycle 1. - In the process of folding the
bicycle 1 completely, thebicycle 1 is folded by means of thefolding mechanism 14, whereby thefront wheel 2 is shifted to a position at the left side of the rear wheel 3 (only therear wheel 3 is shown in FIG. 8). Further, thekick stand 9 is kicked toward therear wheel 3 to thereby cause theauxiliary wheel 17 to place on the ground. Then, thecarrier portion 5 d of therack 5 is caught by thelocking mechanism 22 fixedly attached to thefender 21, whereby thefront wheel 2 is fixed to therear wheel 3. Thus, thebicycle 1 is placed in the first folded state. In this state, thebicycle 1 is supported by thefront wheel 2, therear wheel 3, and theauxiliary wheel 17, with theseat tube 16 disposed generally perpendicularly with respect to the ground GL and thecarrier portion 5 d of therack 5 disposed generally horizontally with respect to the same. Therefore, therack 5 is not inclined even in the folded state of the bicycle, so that it is possible to move thebicycle 1 with the baggage on therack 5. Further, as shown in FIG. 9, thelocking mechanism 22 holds thefront wheel 2 such that the lines of intersection where the planes of rotation of the respective front andrear wheels bicycle 1 in its folded state is moved straight, therear wheel 3 and thefront wheel 2 perform smooth rotation. Moreover, since thesprocket chain 34 disengaged from the rear wheel-side sprocket 35 is held by the chain-holdingmechanism 27, thepedal 32 is inhibited from being rotated with rotation of therear wheel 3, whereby contact or abutment between the pedal 32 and theframe 4 is prevented. As a result, differently from thebicycle 71 of the related art, thebicycle 1 can be easily moved without any need to be lifted. - Further, when the
bicycle 1 is put away or stored, theupper post 42 is pushed into theundertube 41 of thesteering section 7, and the upper part of the extension beam 43 (lower andupper metal retainers pipe 41 c is folded by means of thefolding mechanism 41 b. As a result, thebicycle 1 is placed in the second folded state as shown in FIG. 10. Thereafter, when thekick stand 9 is kicked forward, thebicycle 1 is supported by the front andrear wheels kick stand 9, with theauxiliary wheel 17 slightly off the ground GL. In this state, theseat tube 16 is disposed generally perpendicularly with respect to the ground GL. Therefore, if the position of thesaddle 53 is adjusted by the saddle angle-adjustingmechanism 52 such that thesaddle 53 extends horizontal, it is possible to sit on thesaddle 53, i.e. to use thebicycle 1 in its folded state as a chair. In this case, the height of thesaddle 53 can be set as desired by a height-adjustingbolt 54 appearing in FIG. 10. - As described above, the present invention makes it possible to reduce the size of
bicycle 1 in its folded state while maintaining the running stability of the same in its extended state. As shown in FIG. 11, aspace 1 a occupied by the foldedbicycle 1 is much smaller than aspace 71 a occupied by the foldedbicycle 71, which is shown by dotted lines in the figure. Therefore, thebicycle 1 can be easily put away in a storeroom, a trunk of a vehicle or the like, and also easily carted about. Further, since the foldedbicycle 1 can be used as a cart or a chair, so that when the user is traveling with thebicycle 1, he can easily carry baggage on the foldedbicycle 1 or take a rest sitting on the same. - It should be noted that the present invention is not limited to the above embodiment, but the construction thereof can be modified as required. For example, although in the embodiment, the
frame 4 does not have a top tube or a seat stay, the framework of the folding bicycle according to the invention is not limited to that shown in the embodiment. Further, although in the above embodiment, thesprocket chain 34 is held by thearms rear wheel 3, it is possible to hold thesprocket chain 34 by means of thearm 28 and the derailleur by using the derailleur in place of thearm 29. - It is further understood by those skilled in the art that the foregoing is a preferred embodiment of the invention, and that various changes and modifications may be made without departing from the spirit and scope thereof.
