The present invention is more particularly related to a bicycle or similar vehicle which can be easily manually switched between an upright operation mode and a dense disassembly position. [Previous Technology] Today, bicycles are widely used and accepted as a means of transportation. The design and construction of bicycles has been carried out in the past, and the same will be the future: long-term progress. Today's example of the oblique # -type bicycle, reveals the U.S. Patent No. 08 / 226,898, which was established on the 13th of May, and is currently the U.S. Patent No. 5,486,015, and the U.S. No. Exclusive patent No. 8 / 572,239, now US Patent No. 5,823,554, both of which are incorporated herein by reference in their entirety. In the early development, the steering and power functions of standard bicycles were controlled by the front wheels. System < The steering device includes a handlebar attached to a steering column of tens of thousands and is used as a tool for the operator to control the steering of the vehicle. Therefore, the handlebar / steering support device is used to rotate the front wheels. Any manual rotation of the handlebar causes the same front wheel angle rotation. When in motion, the early systems basically provided driving power from the legs of the rider directly to the front wheels. Therefore, the drive system usually includes a foot pedal that the rider can reach. A pedal is laterally outward and placed on each outside of the vehicle. The connecting element is used to rigidly attach the pedal to the front wheel, for example, at the corresponding end. Although early direct drive systems were still effective for some limited purposes, 84670.doc 200418682 has various disadvantages. For example, the average operator cannot physically turn the front wheel assembly through the foot pedal in order to reach a higher speed (ie, more than 15 miles per hour) (revolutions per minute). In addition, even when this direct drive system is used with large diameter front wheels (such as 5 feet), high-speed travel cannot be achieved. Another disadvantage that was a feature of early direct drive systems was due to the rigid connection of the front axle to the foot pedal. This connection requires the pedal to rotate around the steering axis of the vehicle when the front wheels are turned. This feature makes it extremely inconvenient for the operator to steer the vehicle. Subsequent design efforts to allow an increase in maximum vehicle speed without the use of large-diameter front wheels eventually led to the introduction of gears into the vehicle drive system. The result is a significant increase in the maximum speed of the bicycle. The developed sprocket gears and various sprocket gear systems additionally allow the pedals to be fixed to the vehicle frame instead of the front axle. In this way, the problems caused by the pedal rotation during the steering can be avoided. The biggest success is the rapid progress in the development of various bicycle operating systems through the use of chain gears. On the + day, developers continue these achievements to produce new and / or improved gears and gear units that meet various predetermined needs and goals. In the past, the era has seen countless changes in bicycle design and various additions and improvements. Today's standard bicycles generally include a metal frame mounted on two iron wire spoke wheels arranged one behind the other, a pad, a handlebar for steering, and a pedal for driving the vehicle. Large: points Today, the bicycle structure is a steering action performed by the front wheels, and the driving (power) of the vehicle is provided by the rear wheels. The full length of such devices tends to exceed 5 sighs. Vehicle weight is reduced by more or less 84670.doc -6- 200418682 by using materials such as Shaoxing or fiber-reinforced resin. The weight of this material is 10 tellurium. The treadmill structure can be obtained as low as irrespective of the wide use of the bicycle as a high-altitude vehicle. What is the wide access of the vehicle? Knights always encounter problems when they reach their destination. For example, there may not be adequate facilities for bicycles at the destination. Unfortunately, when bicycles are temporarily parked and cherished, they are often burglars and / or targets. Another problem—the problem is the use of the bicycle only during or behind a limited period of travel. In this case, the use of bicycles = existence ', especially the largest and / or heavy bicycles, will always be more expensive. For example, for a knight, it may be necessary to temporarily carry a bicycle on a different transportation vehicle (such as a bus, temple, train, airplane, etc.). * There are only suitable tools that can reach a specific expected location. In order to increase the number of vehicles by mass transportation, the knight expects the future demand of using a bicycle after arriving at the location. It is not only inconvenient to hold a conventionally known conventional footwall cart, but also includes vehicles constructed from extremely light materials. This is a major problem due to the length of the body. The standard body length is usually equal to or greater than the average height of a person. Therefore, just because of the vehicle's space occupation: problems can be prevented ’either by preventing the rider from carrying it everywhere, or by storing it safely when not in use (such as when in the workplace). Development efforts to reduce the length and width of vehicle carrying forms have been upgraded to bike designs that include various folding issues. Although the known folding 2 bicycle design ’shows many differences from the performance of standard bicycles, they continue to use the basic steering and power drive system of ordinary bicycles. So far, the reduction of the carrying shape obtained by the known folding bicycle 84670.doc 200418682 ::: small (volume) has not been proven to be sufficient to increase its general acceptance and access to operation-standard bicycles, power (power ) Must be applied by knight leg: vehicle pedal. -In general, this-operating force extends in the generally vertical direction. As a result, knights often use a mounted position to facilitate this force. The usual position taken by the knights tends to make the total vehicle / knight height greater than the team. As a result, the large frontal cross-sectional area of the knight's body was exposed and became a source of resistance. This known type of bicycle design reduces the area of the front section exposed by the rider compared to those encountered by more standard bicycle structures. Such ‘vehicles are known as reclining bicycles. The design of the oblique # bicycle allows the rider to take the position of the towel during the operation of the vehicle. The lean-cut treadmill has been a superior design for riders to maintain current short-range speed records. Regardless of its success, reclining bicycles equipped with standard front-wheel steering and rear-wheel drive require a long drive chain placed under the rider. Unfortunately, this: The drive chain is a potential source of resistance because it tends to increase the height of the vehicle, and therefore increase the area of the front section. According to basic theory and physics, when the direction of the force applied to an object: straight to the direction of movement, there is no transfer of energy (momentum). If there is no energy / kinematic transfer, the object remains in its previous state, such as immobile or a certain linear motion. Computationally speaking, energy transfer can be represented by force vector, motion vector, and its forming angle "cosine product". When the force and motion vector form a right angle, the product is zero because the cosine of the right angle is zero. When power and motion are parallel, the most efficient energy transfer is achieved. 84670.doc 200418682 J. All commercial bicycles traditionally use a circular cranked light pedal for riders. When equipped with a circular crank, the thrust generated by the rider on the safety bicycle: the thrust generated by the rider will be effective when the pedal is located in front of the pedal axis and the double pedal is used with a parallel pedal. It is about a half of the rotation period. Since effective power transfer = the most difficult in minute rotation cycles, any momentum gained may < miss. For —slant # bicycles, the most efficient power shift is difficult to obtain, but the overall efficiency of the pedal cycle is the same. From the description, T is used to ascertain the various advances in the design and construction of the bicycle. According to various embodiments, a human-powered ground vehicle may be provided.

The following discussion of the preferred embodiment of the present invention will naturally be used as an example only. Therefore, 'this discussion is by no means meant to limit the scope of the invention, the application of the invention, or the use of the invention. Referring first to FIG. 1, a preferred embodiment of a human-powered ground transportation vehicle 10 is shown in a side view and a front view. The vehicle 10 is equipped with two wheels. One of the wheels 12 is placed at 84670.doc -15-200418682 and the number of wheels is 14 million. This—the universal type of vehicle, is well known (also can be cited in this article) as a bicycle. The bicycle 10 in FIG. 1 is described in a fully upright operating mode. The reference letter L indicates a distance of approximately 1 foot along the longitudinal axis of the vehicle. This length is used for general purposes only and is not meant to be limiting. It should be understood that the present invention is anticipating the various sizes, shapes, and dimensions of a vehicle constructed in accordance with the meaning of this document. The schematic bicycle 10 includes a number of basic accessories, such as a frame 16 that spans the distance between the wheels 12, 14; a seat 18 for the rider to ride; a handle 20 for steering; and a pedal 22 for driving the vehicle. And 24 (on the right and left respectively). With regard to vehicle steering, the present invention employs a device for manually turning the front wheels 14 by means of a handle 20 and a steering column 34 as required. With regard to vehicle driving, the foot force applied to the pedals 22, 24 according to the teachings of the present invention is transmitted to the front wheels 4 through a gear system and a chain arrangement. The vehicle 10 is different from a bicycle in design, structural configuration, and operation. For example, as mentioned earlier, most of today's bicycles are steered by wheels placed in the front, and the drive (force) of the vehicle is provided by wheels placed in the rear. On the other hand, various embodiments of the vehicle 10 may cause both steering and driving to be effected via the front wheels 14 at the same time. Another difference between the bicycle 10 and the ordinary bicycle is the interval relationship between the positions of the pedals 22 and 24 relative to the seat 18. From the picture! It can be confirmed that the knight applies a force suitable for operating the bicycle 10 along a path extending from the area adjacent to the seat 18: Γ to the areas of pedals 2, 2, and 4. Since the various embodiments can be provided with the pedals 22, 24 at a position along the frame 16 taking the front area, this force follows a diagonal line toward the lower front end of the vehicle. Therefore, the direction of this operating force 84670.doc -16- 200418682 ’has a substantial horizontal component. Because of & during the operation of a vehicle constructed in accordance with various embodiments, the left riding posture is lowered to reduce the overall height. This position of the knight can help reduce resistance. This is in sharp contrast to prior art bicycles that basically had a foot pedal at the bottom of the rider. As mentioned earlier, this type of bicycle requires vertical operating force, which tends to place the rider in an upright, high-resistance operating position. The unique design of the present invention is to provide a component configuration which not only distinguishes the bicycle 10 from most commonly known bicycle structures in the structure, but also strives to transform the bicycle 10 between its upright operating form and its densely folded form. 'Reduce the possibility of causing various inconveniences. It is to be expected that certain important structural characteristics and various advantages of the present invention will be apparent from the discussion and description presented above. Such characteristics and advantages will become clearer when studying the physical materials and reading various additional comments in addition to the suggestions presented below, and further priority of the present invention will be easy to recognize and understand. The frame 16 shown in the embodiment of FIG. 1 is composed of a plurality of divided and distinguished frame sub-members or regions. In particular, the frame 16 (as shown) includes a front area 26 placed in front of the vehicle 10, a rear area 10 or the rear area 28, and a middle area along the vehicle. The intermediary intermediate regions 30 are arranged across the spatial distance separating the front and rear regions (26 and 28). The regions (26, 28, and 30) can act as a single frame once the regions are properly aligned sequentially (ie, before, after, after, and after one), as described in more detail later, and joined appropriately. Individual areas (26, 28, and 30) of the frame body 16 can be uniquely adapted as components for supporting specific vehicle-related accessories. In addition, each zone, 84670.doc 200418682 28 and 30) is deliberately shaped to achieve and / or allow for desired results and goals, and one of those points is usually not related to the vehicle frame. The structure of Figure 1 can be exemplified as most of the frame areas (26, 28, and 30), which express this consideration through design, construction, and through a specific structural configuration. As shown in FIG. 1, the front area 26 of the frame 16 can be used to support the foot pedals 22-24 and related structures. As also shown, each individual pedal 22 is connected to one of the ends of the respective crank arms or levers 33 and 35 (on the right and left sides, respectively). Such a connection is expected to have a form that allows the pedal to rotate. The connection of the pedals can be obtained by inserting a short pivot lever that extends from each pedal (22, 24) into an individual socket formed in the outer end area of each crank arm. Then, each of the crank arms 33, 5 is connected to perform a full angular motion around a different mandrel 36. The crank arm can be connected to the frame connection point 36 (only one of which can be seen in the diagram). The connection method is the connection between each pedal and the crank arm, and it can swing forward and backward around its individual mandrel 36. The mandrel 36 for each crank arm can be placed adjacent to the foremost area of the vehicle, and can pass laterally through the side surface of the other frame Shao position 26. The pedal can be traversed through the crank levers 33, 35 Connected to the first gear 8G, the crank rod is connected to the roller clutches 37, 38 or a device that can transmit the clockwise pedal rotation to the first gear. The movement of the reciprocating pedal arm is limited to a range of 40 degrees from the center position. The central position is generally vertical to the ground. The direction of pedal movement and the direction of force application are generally parallel to each other, which allows high-efficiency (greater than dove) power transmission. The levers 33, 35 may include at least an offset element, which is offset by The rear direction of the vehicle. The deflection element can be a spring. For example, the deflection element can generate a resistance of about 3 to about 5 pounds. At least the pressure is ~ ~. The pressure is 84670.doc -18- 200418682 The cups 33 and 35 can move at the same time. Towards the front of the vehicle When the lever ", the vehicle 35 moves Wan 'to the vehicle drive wheels 14 may be rotatably push the front of the vehicle. The roller clutches 37 and 38 allow the levers 33 and 35 to move to the rear of the vehicle without disturbing or hindering the vehicle from moving, or rarely disturbing or hindering the vehicle from moving forward. 0 = Duplex pedal allows the rider to propel the vehicle without Substantially changes the foot of the knight. Unlike the difference between the maximum and minimum foot height, which is the round material of the crank outer diameter (between 12 and ㈣), the reciprocating pedal allows the difference between the maximum and minimum height to be less than 5 忖. In prior art installations, the reclining bicycle rider who forced the short wheel base outside with a large crank took a lying down position. The reciprocating pedal design allows the rider to take almost any desired sitting position. One or more bearings, such as balls, rollers, or hybrids, can be used to fix the rotation axis of the gear pedal. Two bearings separated by a distance greater than 丨 inches can reduce the bending stress caused by uneven load due to the action of the pedal. Two bearings separated by the maximum applicable distance can be used to minimize the stress related to bending resistance. The front area 26 provides additional support for certain other accessories, which may include:-a gear system constituting the # sub-vehicle drive system; connection elements that cooperate with the vehicle's steering column configuration 34; and% contact the middle frame in the front frame area A connection element is added to the area of the area 30 with an intersection. Fig. 4 depicts the transmission elements of the reciprocating pedal assembly, which includes pedals 22, 24 and crank levers 33, 35. In order to obtain higher power transmission efficiency, a reciprocating pedal assembly can be used instead of a circular pedal assembly. In order to cause the one-way rotation of the first gear 80, the roller clutches 37, 38 (on the right 84670.doc -19-200418682 and left respectively) are used to ensure that the first gear 80 will only be viewed clockwise and on the left side of the vehicle. ) Rotation, so that the vehicle can be pushed 4 forward by the forward movement of the crank levers 33, 35. At the same time, when the crank levers 3, 3, 5 are moved back to the rear of the vehicle, there is little or no continuous obstruction to the forward movement of the vehicle. The roller clutch used in this article can be built into the sprocket, wheel, or wheel bearing assembly, which allows the wheel or pedal assembly to rotate freely in the _ direction, and @ when in the other direction against-the gear or wheel moves. For example, a pedal assembly including two pedals, a crank shaft and a sprocket can generate power when moving in one direction by locking the crank shaft facing the sprocket, and the crank shaft can freely rotate in the opposite direction . The first gear 80 engages the second gear 90, which will only rotate in the counterclockwise direction. The second gear 90 is fixedly connected to the first gear 86, so that the second gear 90 and the first sprocket 86 rotate together. With the pedal placed below the rotation axis%, the power stroke is clockwise.胄 轮 啮 # can be-reverse rotation direction, square π so that the two gears 8 0, 9 0 are the most necessary components to change the rotation direction. All subsequent power transmission configurations can be obtained with a chain. Keep the direction of rotation. The outer diameter of the first gear 80 can be larger than the outer diameter of the second gear, which can achieve a higher wheel rotation rate. The middle area 30 of the frame body 16 can be connected to the Kewan area 26 at an upper point 40 and at a lower point 42. The connection point 40 and the heart are arranged along the area where the two frame areas 26 30 meet at the position 忒. Although any suitable connection means may be used, the present invention contemplates that one of the connection points 40, 42 may utilize a frame-turn connection element to allow the -frame region to rotate relative to the other. The mandrel for this rotation can be placed at the connection point 40. The rotating frame shaft is placed at the connection point 40, which can provide a very efficient structure in order to obtain a close-fitting shape in the period when the bicycle 10 is folded. With this configuration, when one frame area is folded around other frame areas, the frame area (26, 30) is obtained. < substantial overlap. If the rotation point 40 becomes a potential source of structural problems in the frame 16, it may be desirable to build an area that is reasonably enlarged as much as possible to enhance the strength of the frame. The above structural characteristics and configuration help provide a structure that can achieve the smallest vehicle folding size. As shown in the embodiment of FIG. 1, the seat 8 is supported by a part of the frame 6. Although the seat 18 may be connected along the top side of the middle region 30 (as shown in the figure), it is expected that in some cases, the seat 18 may be connected to the top of the rear frame region 28 in some cases. Any known connector device known to the skilled artisan may be used to effectively connect the seats 8 along the frame 16. This article looks forward to a standard configuration that uses a rod that has one end fastened to the seat and the other end fixed to the socket of the vehicle frame. Such a connecting element can also provide a socket device, which can be used to adjust the seat position between various predetermined positions. Middle Zone 30 < The top side can have openings of the same pitch for the connection of the seats, so that the seats can be connected to the openings of different groups and placed at the most suitable position for the foot length of the rider. The seat know * 18 can also be used as a carrying case. The lower part 18 of the seat Η and the upper position 18b of the seat 18 can be connected by a hinge 21. The lower part may include rollers 141, 142 for moving the folded container over the laying surface, and fixed and retractable rods for connecting the seat to the middle area of the frame. Rollers 200 may be included in the seat / carrying case as needed, alternatively, or in addition to one or more rollers 141, 142, while further moving the folded vehicle 10 over a section such as a paved section Or unpaved area. The upper part 18b 84670.doc -21-200418682 may include a money surface i43 connected to the front end of the upper part m by a hinge 144, and a back pad 145 adapted to be rotatable to the position shown in the figure. In the folded configuration, the back pad 145 can be rotated around the mandrel 146 to make it flush and / or temporarily connected to the seat surface 143, or the ㈣ 145 can be removed and placed in at least part of at least the upper portion 18b and the lower portion 18a of-within the composition to grab inside. Under operating conditions, the space behind the back pad 145 can be used as the storage space 154. The hinge 148 can be installed to provide easy access to the wildlife area 154 via the storage cover 147. From the side, there are triangular ridges below and above the carrying case. This option: the shape, can make the carrying box such as a full length of about 9 inches, will not add the height of the middle area of the knight mount during the operation mode. The carrying case may have a handle for easy use. The handle can be placed in the carrying case, making it easy and convenient to roll the carrying case on the floor. The rear frame area 28 follows the rear vehicle area and contains appropriate structural supports that can hold the rear wheels 12. In particular, the rear area 28 provides a device structure suitable for supporting the rear wheel 12. Therefore, the rear wheel 12 can be installed to freely rotate around its center wheel pump 13. According to this embodiment ', the rear wheel 12 can follow the front wheel 14 at any time during travel. Silly area 28 can also contain ,,,-, < · Shock support 枉 50. Individual ends of the shock-absorbing struts 50 can be rigidly connected at the axle 51, and connected to the upper portion of the rear area 54, and at the same time connected to the wheel coupling block 55 at the axle 52. The wheel connection block 55 can also be connected at the wheel 53 after the connection is rigid; the lower part of the area 28. The through hole 叼 in the middle area 30 and the through hole 48 in the rear [domain 28] can be used to fasten the two areas. A sliding element 4 is used to fasten the through-hole 叼 and "fasten 84670.doc -22-200418682 when the two areas are rotated to the operating configuration. Once the bicycle 10 is folded, the rear area 28 can be further adapted to achieve the best results. Rotation in the form of tightness. This rotation can be performed around the axis 46 of the vertical alignment, which allows the rear area 28 to swing laterally outward and around. In the various embodiments shown in FIG. The single full-length sweep (that is, starting from one extreme point and continuing until reaching the other extreme point) is rotated at an angle of about 180 degrees. In this way, the rear area 28 can be swept over a sufficient angular distance to reach a relatively large angle. The best final position is adjacent to the general vertical plane of the middle region 30 'and is substantially parallel to the middle region 30. This structure also helps to ensure that the smallest vehicle folding size is obtained. In addition, referring to Figure 2, the middle region 30 and the rear region are shown Details of various embodiments of 28. One side of the element connecting the middle region 30 and the rear region 28 can contain two double hinge joints 46, 47. The other side can include a sliding element 48 The π moving element 48 is suitably activated by a locking pin 49 that can rotate around the spindle 46. The locking pin 49 is usually locked in its lower position, except during the folding or unfolding process of the vehicle. The sliding element 48 and the crank lever 49 are provided with teeth Teeth to obtain the position of a crank lever. The sliding element can be operated to engage the hinges 5 丨, 52 'which can rotate around the mandrels 53, 54 located at the rear 30 of the middle area of the frame. It can be shaped into the following area 55. -The frame can be made of steel, inscriptions, alloys, or fiber-reinforced plastic resins. 16. Of course, any other material familiar to those skilled in the art can be used as the frame structure. .Slip bolts or other suitable elements can be used to fasten and maintain the vehicle frame area in the deployed form according to various embodiments. Similarly, a properly folded positioning latch at point 65 can be used to fasten and Keep the vehicle in its folded form. 84670.doc -23-200418682 A general folding bicycle 10 that reduces its overall length and full height can be implemented as follows. First, any element used to interlock the areas with each other. In order to cause the first folding, the rear area 28 of the frame can be rotated to the left relative to its related vertical axis, so that the rear area 28 and the middle area 30 of the frame can finally be mutually related. Parallel. The second fold can be obtained by rotating the front frame area 26 relative to its related horizontal axis, so that it substantially overlaps with the middle area 30 of the frame. Seat 18, foot pedals 22, 24 and handle 20 , Can be transferred from the individual operating position to the storage position. The bicycle 10 'can be easily carried and / or stored away (such as on passenger trains, buses, vans, airplanes or other public transportation) Under the seat of the tool). The folded vehicle 10 can be stored in a cargo box composed of the upper part 1 讣 of the seat 18 and the lower part 18a. According to various embodiments, the front steering strut 34 may include front wheels 14 (including front tires), drive chains 102 and 103, handlebars 20, and other control devices such as brakes and gear shifting elements not specifically shown. The steering column 34 may be connected to the front frame region 26 by two (or more) bearings such as an upper bearing and a lower bearing. The width of the front frame area 26 is sufficiently reduced along the area adjacent to the steering column 34 to appropriately accommodate the steering column 34. The steering column 3 4 can be folded in the upper position. Special folding and unfolding actions can be modified to meet different needs based on the height of the knight and / or any other special preferences. Steering pillar < The top part may include a top plate 62 having a rear hinge shaft 76, a front hinge shaft 76, a front hinge 79, a rear hinge 78, an upright post 69, and handles 67 and 68 (right and left hands). The rear hinge 78 and the upright post 69 may be permanently connected at the mandrel 70. 84670.doc -24- 200418682. The top plate 62 may be at the mandrels 76 and 73, respectively, to permanently connect the front and rear hinges. The rear hinge contains three axes 70, 71 and 72. The upright strut contains two axes 70, 71. In the folded position, all components are at the same level as the outer handles 67, 68, the upright posts 69 on the inner side of the handle, the front hinge 79, the rear hinge 78, and the middle top block 62. According to various embodiments in the assembled form shown in FIG. 6, the front hinge 79 rotates around the mandrel 76, and the rear hinge 78 rotates around the mandrel 73, so that the mandrels 91, 71, and 72 are aligned and locked with each other. The handle can be turned outwards. The steering column. 34 can rotate relative to the front frame region 26 along the rotation axis extending beyond the center of the upper bearing 63 and the center of the lower bearing 64. Angular rotation can reach the limit. For example, angular rotation can be limited to less than about 35 degrees. Unexpected Cavaliers will suffer significant inconvenience due to reasonable restrictions Figure 3 shows what is generally indicated by reference number 59. The connecting rod structure of the vehicle 10. The connecting rod 59 may be arranged along the wheel 14 and the bearings 63 and 64. The “connecting rod” can be constructed and arranged in the form of a large chain around the drive system chain. As described in the above, “The construction and swinging of the connecting rod 59 can provide the appropriate structural strength with the minimum folding vehicle width. It is hoped that it can be arranged at the wheel 14-the ratchet device or the roller away from the "Yi" can cause the accidental rotation of the I tire, which will not cause the unexpected driving of the chain iQ3. Any known arrangement that the skilled person may consider appropriate is It can be used for this purpose. In general, known bicycles are equipped with pedals. Some known bicycles are equipped with pedals. The pedals are placed in the front, with feet placed below the knight, The front can be used in accordance with various embodiments in this 84670.doc -25-200418682 text because it allows the knight to be in a lower position with a reduced overall high yield. The footboards 22, 24 shown in Figure 1 are suitable to surround A mandrel placed in front of the steering column 34 rotates. The reciprocating action pedal that sweeps forward and backward is more preferred than the well-known conventional rotary pedal because it reduces the need to lift the foot. However, the rotary pedal can coexist with the essence of the present invention. The pedal according to the present invention is separated from each other by a sufficient distance (crossing the longitudinal centerline of the bicycle) to allow unimpeded rotation of the front wheels. Human (foot) force is applied to the pedal 22 , 24, which causes the individual crank arms 33, 35 fixed relative to the front frame area 26 to rotate around the mandrel 36. The crank arms ^, 35 are arranged in a mechanical communication with the gears, in response to the crank action and slander The guide gear 80 rotates. According to various embodiments, the power stroke occurs in a clockwise direction. In order to make the gear 80 rotate to follow the direction of the power stroke, an appropriate one-way ratchet or roller clutch configuration can be adopted to allow only gear 80 Move clockwise. The ratchet or roller clutch configuration allows each pedal to engage with the drive mechanism when the pedal is only pushed forward. During the return stroke, the pedal will slide freely relative to the drive gear. In this configuration, manpower can be transferred to the front wheel 14 by moving the pedals 22 and 24 forward and backward along the arc-shaped fan. Those skilled in the art deem it appropriate Known ratcheting arrangements can be used in the present invention to achieve this goal. Now it is described to ensure that the desired reciprocating action acts on the power pedal 22. The " structure. Once one pedal is pushed forward, the other The pedal can be retracted, moved forward, or stopped at the position desired by the knight. This _ reciprocating pedal action can be performed at the same time.-Once the pedal 22 is pushed forward 'the final crank pinch action, induces gear 84670.doc -26 -200418682, using two = Γ wheel 80 and gear 9 ° are in mechanical communication. = Gear 90 rotates in response to the action of gear 8. Tooth 1: Cooperative configuration, make gear 9. Rotation is in the counterclockwise direction. Then = The gear 90 and the chain are directly mechanically aligned and rotated by the action of the wheel 90. 'Round 9. And the sprocket 86 can be configured to rotate counterclockwise. The gear 90 and the sprocket 86 are fixed. When the gear 90 rotates, the sprocket δ6 also rotates in the same direction. The gear used is preferably made of a high-strength material such as steel. Any other material deemed appropriate by the skilled person may be used in the construction of the gear. According to various embodiments, the intermediary power transmission assembly may be as shown in Figs. 4 and 7, including a universal joint connector. According to the various embodiments of FIGS. 4 and 7, the intermediate power transmission assembly includes a gear ⑽ with an internal sprocket 107, which is connected to the second through a universal joint connection of an internal-ring member 1 () 8 and the second The key wheel ⑵ is mechanically connected. Gear 106 is connected and is powered by the gear 86 of the power input assembly in motion through the chain 101 and the sprocket 107. The sprocket 122 communicates with the rotatable sprocket 74 of the front wheel via the key bar 102. The universal joint connector shown in Figure 7 can be directly or indirectly connected to the foot pedal, providing power input. The gear 106 can be fixedly positioned for rotation within the front frame portion. 1 Mounted on the frame 26 < The large through-hole bearing 125 contacts the gear 106 and prevents the gear from moving relative to the housing except for the rotational movement. The large through-hole bearing allows rotational movement of the gear 106 about the rotation shaft 128. An inner ring convex part 126 of a bearing 125 is parked in a corresponding groove and recess 127 formed on the outer surface of the gear 106, while preventing the gear 106 from moving laterally and longitudinally relative to the vehicle frame. The shaft 84670.doc -27- 200418682 can be mounted on the frame portion 26 in any way, such as by screws, adhesives, friction fits or narrow brackets. 'The gear 106 includes a sprocket 107, which has a built-in chain 101, and at the same time can transmit power from the gear% to the gear. The gear 106 has a circular tube shape, and has a hollow central part with a built-in member. And the universal joint connector 2 which is a part of the invention may be a universal joint in the figure, although other universal joint connectors may be considered in the field of various embodiments. The universal joint connector 105 shown in FIG. 7 includes a gear 106, a ring member 108, and a sprocket 122 rotatable on the wheel axle 120. When the rider applies the vehicle in a straight forward direction, the axle 120 of the sprocket 122 rotates around the rotation axis 128 in cooperation with the gear 106, and the sprocket 122 rotates in a plane parallel to the rotation plane of the front wheel. Therefore, when the chain 102 transmits power from the sprocket 122 to the sprocket μ of the front wheel, no torque is introduced to the chain 102. During the turning movement of the vehicle, the wheel axle 120 rotates around a rotation axis staggered relative to the rotation axis 128, but the sprocket ι22 continues to rotate in a plane parallel to the rotation plane of the front wheel, and no torque is introduced into the chain 102 again. According to various embodiments, at least one sprocket or at least one sprocket assembly may include or may be replaced by a derailer system having a plurality of sprocket wheels for adjusting the degree of impedance required to rotate the driving wheels of a human ground vehicle. The derailment system may include at least two sprocket wheels that are fixedly connected to each other, and one or more smaller sprocket wheels, metal wires, offset devices, adjustable chain tensioners, and / or suitable for moving a chain from a sprocket wheel. Assembly piece to the guide of another sprocket. Human-powered ground vehicles may contain more than one derailer system. For example, in a sprocket assembly containing a derailer system, the sprocket 122 may be replaced or may additionally include a plurality of 84670.doc -28-200418682 sprockets. The derailer system can be mounted on the wheels 14. Derailment systems can replace sprocket 74. The front parts of the vehicle 58 and 59 or rigid arms are rigidly attached to the front wheel axle (not shown) in a manner that allows the front wheel to rotate on the wheel axle. The axle 120 of the sprocket 122 is rigidly attached to the forks 58 and 59 on the opposite side or the same side of the sprocket 122 so that the axle 120 can rotate. When the steering column 34 rotates around a rotation axis, the front forks 58 and 59 also rotate around the same mandrel due to their rigid connection with the steering column. Similarly, the axle 120 and the sprocket 122 also rotate around the same mandrel when the steering column 34 rotates due to the connection between the split members 58, 59 and the axle 120. The right yoke 59 and the left yoke 58 of the steering column 34 may include spring damping columns 92, 93 (right and left). The front wheels can be attached to the wheel connection blocks %% (right and left). The end of the shock strut can be attached to the shape and the wheel connection block (59 to 95, 58 to 96). The positioning of the chain 103 enables the vertical movement of the wheel 14 and the shock-absorbing pillar without interfering with the rotational movement of the chain 103, the sprocket 74, or the sprocket 220 that is rotatably fixed to the wheel 14. The universal joint connector can function as follows. The gear 106 may have two convex bearings 109, 110 'which are integrally formed with each other, or may be separately mounted on the surface of the inner ring of the gear. The bearing can also be introduced into the through hole that extends from the outer surface of the gear 106 into its inner surface and is fixed by welding, friction fit, adhesive or other methods. The bearings 109, 110 may protrude from the inner wall surface of the gear 106 into the recesses or core holes 129, 130 passing through the outer wall surface of the annular member 108, respectively. Although the embodiment ^ has a core hole for receiving the bearings 109 and 110, it should be understood that it is possible to use a recess instead of a through hole to build the bearing. 84670.doc -29- 200418682 The key wheel 122 and its axle 120 may be considered as a part of the intermediate power transmission assembly, which may also include a ring member ⑽ and a gear 根据 according to various embodiments. The sprocket m transmits power from the intermediary power transmission assembly to the key wheel 74 through the chain 1G2. The sprocket 122 may be driven by the wheel sleeve 120, the wheel # 12 may be driven by the convex member or bearing 、, 113, the convex member or bearing 112, 113 may be driven by the ring member ⑽, and the ring member 108 may be driven by the gear 106. Therefore, when mechanical power is supplied to the power input assembly, the power is transmitted to the front wheels via the intermediary power transmission assembly. The sprocket 122 can be rigidly connected with the wheel shaft 120 ° to rotate therewith. The wheel shaft 120 can be rigidly connected with the convex part or the bearings 112 and 113. When the bearings 112 and 113 rotate around the wheel shaft 120 and the rotation shaft, the transmission rotation moves to the wheel shaft 120, and then the transmission rotation moves to the sprocket 122 »as shown in the figure. As shown, the wheel axle 120 can be equipped with an enlarged portion 121 having a cylindrical opening through which a sufficiently large diameter is passed for built-in bearings ι2, 113. According to this embodiment, the bearings 112 and 113 are each made of a single cylindrical metal block or metal rod such as steel. The rods constituting the bearings 112 and 113 have an outer diameter which is only slightly smaller than the diameter of the round-shaped opening through hole 121. Therefore, a snug fit of the bar member in the opening is provided. Then, the rods can be welded in the openings to fix them, or they can be bonded, frictionally fitted or deformed by other means. A fixing screw can also be used to fix the rod in the opening, as long as a rigid connection between the bearings 112, U3 and the axle 120 is obtained. If the fitting of the rod in the mouth is extremely tight, it does not need to be welded or the rod is continuously tightened. Alternatively, if the bearings i 2 and 1 Π are directly welded to the axle 120 or are integrally formed with it or other rigidly connected axles, the enlarged portion of the axle may not be required. The rotation of the bearings 112 and 113 may be driven by the rotation of the ring member 108, which is then driven by the rotation of the gear 106. The bearings 112 and 113 can be respectively placed in the recesses or core holes 132 and 133 of the ring member 108 in 84670.doc -30-200418682. Although the various embodiments show reference numerals 132, 133 for through holes that completely penetrate the wall surface of the ring member 108, it should be understood that recesses may be used instead of through holes to incorporate bearings. The relationship between the bearings 112 and 113 and the core holes 132 and 133 respectively allows the bearing to be confined in the core hole, but it can be kept sufficiently loose in the core hole to allow the pivotal movement of the bearing. The bearings 112, 113 and the axle 120 may be allowed to pivot about a mandrel defined as passing through the center of the bearings 112 and 113 simultaneously and substantially perpendicular to the axle ω20. Similarly, the bearings 1 09 and 1 10 may be confined within the core holes 1 29 and 130, respectively, but remain sufficiently loose to allow the pivotal movement of the ring member 108 on the bearing. Therefore, the annular member i can be allowed to pivot about a mandrel defined as passing through the centers of the bearings 109, 110 simultaneously and through the centers of the core holes 129, 130. As a result, even if there is an oblique relationship between them during the rotation, the universal joint connector can allow sufficient effective transmission force from the motion force input assembly to the front wheels. According to various embodiments, the core holes 129, 130, 132, and 133 can be much larger than the bearings 109, 110, 112, and 113, respectively, and sleeve bearings, bushings, needle roller bearings, or other anti-wear devices can be configured Between the bearing and the core hole. In various embodiments, the diameter of the axle 120 may be larger than the diameter of the bearings 112, 113, which may allow more power in less effort than when the diameter of the axle 120 is smaller than the diameter of the bearings 2 and 113. If the bearings 112, n3 are configured to extend over a single bar, a larger diameter wheel axle 120 may also be necessary. To construct a universal joint connection, one method of assembly involves providing more than one-piece ring members such as two semi-circular pieces. The ring member 108 may include two semicircular members 1440 and 141 fixed with screws 142. If the bearings 109, 110 8467〇.d〇c -31- 200418682 are pressed across the wall surface of the gear 106 and directly enter the core holes 29, 130, respectively, the ring members need not be divided into semi-circular pieces. However, one or more detachable areas of the ring member 'may allow the bearings 112, U3 to enter the core holes 132, 133, respectively. 0 If the bearings 112, 11 3 are configured as a single rod extending beyond the opening at the position 12 1 'You can insert the axle 120 into the annular member 108 without disassembling the annular member, and then insert the rod into the central hole 132, the opening at the axle portion ι21, and the central hole 133. If the bearings 109 and no are pushed over the internal hole of the gear 106, they can also be inserted into their respective internal holes without disassembling the ring member i08. Therefore, the ring member 108 can be provided as a single piece without assembly or disassembly. It is understood that the two-wheeled and three-wheeled embodiments can be constructed using various embodiments. The above-mentioned vehicle frame region can be obtained by processing aluminum materials (such as blocks) into the above-mentioned shape. It is of course desirable to construct the vehicle of the present invention using a low-cost production technique suitable for the selected material. Casting, forging, forging and / or welding are considered to be appropriate production techniques. Forging may be suitable for use in the present invention (structure elements.

The gear 90 is fixed to the sprocket 86, so that when the gear 90 rotates, the sprocket 86 also rotates in the same direction. The chain wheel can pass 84670.doc -32- 200418682 from- The wheel rim and one or more sprocket wheels 199 are drivingly connected to the rear wheel i2. The key wheel 86 and / or the sprocket wheel 199 may be replaced by a derailer system having, for example, more than one sprocket wheel, a chain guide and a Adjustable chain tensioner. When the wheel 12 or the axle 13 is rotated in ~ directions, it may have a ratchet device that does not allow power to be transmitted ^ or ^, but when it is rotated in the other direction, it may allow power Teleport Such as the free-wheel runner mechanism. Figure 9 is a perspective view of the folded vehicle. The vehicle frame has been forwarded along the mandrel to the front of the vehicle and at the same time folded along the mandrel 54 toward the rear of the vehicle. When the vehicle frame completely surrounds the mandrel When the 40 is folded, the spindles 42 and 65 are aligned.
