Description of the Invention (4) and the rear axle 43 are supported by a front fork 16 and a main frame on the side of the rear wheel, respectively, by means of a cantilever support structure. twenty three. That is, in the embodiment of the present invention, the front fork 16 and the main frame 23 each form a branch. In this embodiment, the front fork 16 and the main frame 23 are respectively disposed on the left and right sides of the bicycle body. The structure of the frame connecting portion 50 of the present invention will be described below. The front frame 21 is generally formed by a hollow member having a cross-sectional shape of a longitudinally long circular shape. The front end portion of the front frame 21 is integrated with the front tube 14 and the rear end portion is provided with a flange 51. On the other hand, the cross-sectional shape of the carriage 22 is also a vertical oblong shape having a shape substantially the same as that of the front frame 21 described above, and is formed of a hollow member. A flange 52 is formed at a front end portion thereof. However, the front frame 21 and the carriage 22 are not necessarily hollow bodies. The cross-sectional shape is not limited to an oblong shape. The above-mentioned pair of flanges 51 and 52 are stably joined by their mating surfaces, and are hinged (not shown) on one side of the flanges so as to be able to bend freely at 180 degrees. A well-known coupling 53 such as a screw or a nut is provided on the other side of the hinge portion. In this case, for example, a screw fixed with a butterfly nut on one side of the flange 52 can be fixed, and a cut groove on the other flange 51 can be used to lock the screw. A simple coupling device constitutes the frame connection portion 50. However, in the illustrated embodiment, front wheels FW and rear wheels RW use wheels with different diameters. In this case, the heights of the axles 45 and 43 of the two wheels must be different. However, in the present invention, the angle between the abutting surface of the flanges 51 and 52 and the straight line connecting the axles 45 and 43 is perpendicular, and It has the advantages as described later. In addition, the reason will be described in detail later. The position of the facing surfaces of the flanges 51 and 52, that is, the length of the front frame 21, is relative to the support guide 60 of the main frame 23. 7 (Please read the back Please fill in this page again for the matters needing attention)-• 5 This paper size is applicable to Chinese National Standard (CNS) Λ4 specification (210X297mm) Printed by A7 _______B7 __ of the consumer cooperation of the Central Standards Bureau of the Ministry of Economic Affairs, 5.

That is, the carriage 22 surrounded by these inner parts can be strongly held only by the pressing operation of the top inner parts 63 from the upper and lower end faces and the left and right sides. The carriage lock represented by the symbol 65 in FIG. 5 and FIG. 6 has a structure generally known as a cam lock lever attached, and is rotatably supported by the cam shaft 68. By the lever of the carriage lock 65 in FIG. 5, When the front end is pulled up, the cam surface will retreat from the inner side surface of the sliding frame body portion 61, that is, the combination of the inner parts is released by allowing the top inner part 63 to move upward to release the lock of the carriage 22. Note that reference numeral 69 in Fig. 5 is a stopper of the carriage 22. Although detailed description is omitted, it can be slid up and down appropriately in a groove below the stopper shown in the figure. FIG. 7 and FIG. 8 show the clamping mechanism 70 which is a characteristic part of the present invention in detail. It has a novel structure in which the handle post 12 is slid up and down relative to the front fork shaft 15 by using the front clamp 17. The front cylindrical shaft 77 of the front fork shaft 15 is fixed, and the other side is a square cylindrical portion 78 for inserting and inserting the handle post 12 into a slidable position. A handle post lock 18 is provided at the middle thereof to clamp from left and right. The entire front clip 17 has a first locking effect. Therefore, it is possible to constitute the first means for restricting the relative movement and rotation selection of the handle post 12 and the front fork shaft 15 to a movable state or an impossible state. The structure of the handle post lock 18 itself shown in FIG. 8 is, for example, a well-known combination such as a screw and a butterfly nut, or screwing a rod screw into a screw hole provided in the front clip 17 itself. In addition, the front clip 17 before the front cylindrical tube 77 and the front _ 9 This paper size applies Chinese National Standard (CNS) M specifications (21〇 × 297297mm) (Please read the precautions on the back before filling this page) Order- Printed by the Consumers 'Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. 5. Description of the Invention (^) The fork shaft 15' may be formed with a structure that restricts rotation by, for example, fine teeth. Regarding the clamp mechanism 70 of the most important characteristic part of the present invention, the sliding lock structure of the handle post 12 in particular is described as follows. In the longitudinal hole portion 75 provided in an appropriate position below the handle post 12 in FIGS. 7 and 8, The lower front end portion of the locking projection piece 74 projects more outward than the longitudinal hole 75, and the spring base portion 73 is used to fix the locking projection piece 74 that can be pressed into the longitudinal hole 75 to the handle post 12. Above the inside of the longitudinal hole. Therefore, the handle post 12 at the normal illustrated position is supported by the upper end edge of the square cylindrical portion 78 behind the front clamp π by the abutment of the lower end face of the locking projection 74 fixed by the spring base 73, so that it can be prevented The sliding of the handle post 12 relative to the front clip 17. On the other hand, the locking pin 72 is driven into the lower end portion of the handle post 12, and the protruding portions on one or both sides thereof are fitted into the slits 71 and 71 provided in the lower portion of the rear cylindrical portion 78 and inserted from below. Therefore, by abutting the locking pin 72 on the terminal portion above the slits 71 and 71, the handle post 12 can be prevented from being pulled out upward. In the normal handle position, each member is fixed in the state shown in FIG. 7 and FIG. 8, that is, the locking projection 74 protrudes to the middle portion of the longitudinal hole 75, and the lower end surface thereof abuts the rear cylindrical portion. At the upper end edge of 78, the locking pin 72 is engaged in the slits 71 and 71, and the upward movement and the rotational movement are restricted, and the lever pin lock 18 is used for coupling. As a result, the relative position and rotation of the handle post 12 and the fork shaft 15 can be easily and reliably locked. The relative angles between the locking pin 72 and the slit 71 and the handle post 12 or the clamp mechanism 70 need not be limited to those shown in the drawings. That is, the mounting positions of the locking pin 72 and the slit 71 can be selected in other circumferential directions. In the clip mechanism 70 thus constituted, as long as the handle support lock 18 is non-knot 10 ---:-: --- ----------------------- ^, / ί, / (Please 4--read the notes on 1 side and fill in this page) This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) Printed by the staff of the Central Standards Bureau of the Ministry of Economic Affairs Λ7 B7 V. Description of the invention ( g) the closed state (unlocked), the combination of the handle post 12 of the rear cylindrical portion is released, and only the operation of pressing the head of the locking tab 74 into the long hole 75 with a fingertip, The engagement between the front end surface and the upper end edge portion of the rear cylindrical portion 78 can be released, and the handle post 12 can be slid and dropped freely in the rear cylindrical portion 78. In the state, it can be simply fixed by turning the handle post lock 18. More importantly, in the state where the handle 11 is turned at an arbitrary amount in the unlocked state, since the handle can be fixed at any inclination angle by the rotation fixing of the handle post lock 18, it is extremely convenient for the entire bicycle to be folded down. Fig. 9 shows a state in which the sliding scale of the folding bicycle according to the present invention is once reduced. That is, in order to explain the operation which is very easy to handle in the push running state of the first form of the bicycle of the present invention, first, the bicycle of the present invention in the state of FIG. 4 has a carriage 22 and a main frame 23, especially a support guide. Each member of the lead portion 60 is set to a normal running state shown in FIG. 5. Here, if the front end of the lock lever of the carriage lock 65 in FIG. 5 is pulled upward and rotated around the cam shaft 68, the cam surface of the lock lever rotates, and the sliding frame body 61 from FIG. 6 is rotated. The inner side of the upper part is retracted upward. In this way, the top inner piece 63 can be moved upward relative to the bottom inner piece 62, and by the inclined surfaces 67, 67 of each side end of the top inner piece 63 and the bottom inner piece 62, and the inclined surfaces of the side inner pieces 64, 64 66, 66 slide, so that the side inner parts 64, 64 can leave left and right. In this state, by pressing the frame stopper 69 in FIG. 5 into the engaging groove (unsigned) below it, the carriage 22 is pushed to the rear relative to the main frame 23 to slide to the position shown in FIG. 9. status.

The frame 22 is fixed to the sliding frame body 61 at its foremost position. In this state, the positions of the flanges 51 and 52 of the connecting portion of the front frame 21 and the carriage 22 are designed to be located on the front and rear wheels. The middle of each of the axles 43 and 45 is appropriate. As is clear from the state of FIG. 9 described above, according to the present invention, the bicycle after the previous scale reduction can be used directly in the push walking state, especially because its wheelbase becomes very short, and it can be conveniently small even in a crowd. Excellent maneuverability on turns. In addition, such a state is quite close, so it is not only convenient to store, but also convenient to carry. Figs. 10 and 11 are a side view and a plan view showing a folded state of a secondary scale of a bicycle according to the present invention. By further folding the frame from the middle from the state shown in FIG. 9, the front and rear wheels FW and RW are slightly aligned with their axle portions 45 and 43, and the full length of the seat cushion portion 30 is reduced to the center of the fixed shaft 36 Fold it forward, and turn the handle portion 10 with the handle post 12 partially shortened, and then turn the handle 11 so that the long axis direction is slightly consistent with the frame direction. Specifically, in the once-expanded bicycle in the state shown in FIG. 9, the couplings 53 of the flanges 51 and 52 of the connection portion between the front frame 21 and the carriage 22 are loosened. In more detail, when the other side of the hinge (not shown) of the connecting portion on one side is combined with a screw or a nut, for example, it is loosened, for example, a slit is opened from the engagement of the flange on the other side When the screw or the like is unscrewed, the hinge portion at the connection point of the one side of the two flanges is bent at 180 degrees. At the time of this bending, because the abutting surfaces of the above-mentioned flanges 51 and 52 intersect perpendicularly in the state shown in FIG. 4 before and after the connection 12 square feet > ^ applicable ^ Chinese National Standard YCNS) Λ4 specifications (210X297 male f) (Please read first (Notes on the back then fill out this page)
