Description

1277560 发明, INSTRUCTION DESCRIPTION: TECHNICAL FIELD The present invention relates to a human ground transportation vehicle having two or more wheels such as a bicycle and the like. More particularly, the present invention relates to a bicycle or the like that can be easily manually converted between a vertical operating mode and a densely disassembled position. [Prior Art] Today, bicycles are widely used as transportation vehicles and are well received. The design and construction of bicycles have been carried out in large numbers in the past, and the future will be further evolved in the long run. Today's example of a reclining bicycle reveals US Patent Application No. 08/226,898 filed on April 13, 1994, now US Patent No. 5,486,015, and US No. 5, filed on December 13, 1995. Patent Application Serial No. 8/572,239, the entire disclosure of which is hereby incorporated by reference in its entirety in its entirety in its entirety in its entirety in its entirety in its entirety. In the early development, the steering and power functions of the standard footrest car were performed with the front wheels. The steering system of the system includes a handle that is attached to a steering column and acts as a tool for the operator to control the steering of the vehicle. Therefore, the handle/turning strut device is used to rotate the front wheel. Any manual rotation of the handle causes the same front wheel angle to rotate. During exercise, the early system basically supplied the driving force from the leg of the knight to the front wheel. Therefore, the drive system typically includes a pedal that the rider can reach. A pedal is placed laterally outwardly on each of the outer sides of the vehicle. The connecting element is used to rigidly attach to the pedal at the corresponding end of the front wheel axle. Although early direct drive systems were still effective for some limited purposes, 84670.doc 1277560 has various drawbacks. For example, the general operator is physically unable to rotate the front wheel assembly via the foot pedal in order to achieve a higher speed (i.e., greater than 15 mph) (revolutions per minute). In addition, even when this direct drive system is used with a large diameter front wheel (such as 5 turns), high speed travel is not possible. Another disadvantage of the early direct drive system features was due to the rigid connection of the front axle to the foot pedal. This connection requires the pedal to rotate about the steering axis of the vehicle when the front wheel is turned. This feature makes it extremely inconvenient for the operator to maneuver the vehicle. In order to increase the maximum speed of the valley, it is not necessary to use the subsequent design of the large-diameter front wheel, which eventually leads to the introduction of the gear into the vehicle drive system device. As a result, the maximum rate of the bicycle has been greatly increased. The developed sprocket and various sprocket systems additionally allow the foot pedal to be fixed to the vehicle frame rather than the front axle. In this way, it is possible to avoid problems caused by the pedal rotation during the steering process. The greatest success has been the rapid development of the use of the sprocket in a variety of bicycle operating systems. Today, developers continue to achieve these new and/or improved gears and gears that meet a variety of predetermined needs and objectives. In the past era, there have been numerous changes and improvements in the design of bicycles. Today's standard bicycles generally include a metal frame mounted on two front and rear iron wire spoke wheels, a mat, a handle for steering, and a pedal for driving the vehicle. Most of today's bicycle structures are made for the steering action by the front wheel, while the drive (power) of the vehicle is provided by the rear wheel. The full length of such devices tends to exceed 5 呎. The weight of the vehicle can be reduced to a minimum or less by using, for example, aluminum or fiber reinforced resin or more than 84670.doc 1277560. The weight of the bicycle is 10 pounds. No matter whether the bicycle is used as a vehicle for a high degree of purpose, it is widely used. Secondly, the Cavaliers always encounter problems when they arrive at their destination. There may be no suitable facilities for the bicycle at the destination of the wall. ^ The car is temporarily placed and the target is taken care of. The other encounters are thieves and/or wild, Q4 is only for a limited period of travel: use bicycles for a limited period of time. In this case, the pedal car is in the 'especially the largest and/or heavy-duty bicycles, and will always be a fork s. For a knight, it may have to be temporarily different: on the vehicle. (such as buses, vans, trains, airplanes, etc.) carrying bicycles. *The only suitable tool to reach a specific expected location may be increased for the purpose of transporting the vehicle for the loan, but the Cavaliers expect to use the future demand of the bicycle behind the arrival point. It is not only inconvenient to carry a conventional bicycle known to the present, but also includes vehicles built with extremely light materials. This is the main, because of the length of the body and many problems. The length of the body is usually equal to or greater than the average person's body. Therefore, it is only due to the space occupied by the vehicle: the problem can be prevented, or the knight can be prevented from being carried everywhere, or it can be safely stored when not in use (such as when in the workplace). Efforts to reduce the length and width of vehicle-borne forms have been enhanced to include bicycle designs with various folding issues. While the known folding bike design exhibits many differences from the performance of the standard bicycle, it continues to use the basic steering and power drive for the standard bicycle. Up to now, the reduction in the size (volume) of the carrier shape obtained by known folding bicycles has not been proven to enhance its general acceptance and acceptance. In order to operate a bicycle, power (power) must be applied to the vehicle pedal by the legs of the rider. Generally, this operating force extends in a vertical direction of a large body. Therefore, the Cavaliers usually use the mount position to facilitate the application of this force. The usual position taken by the Cavaliers tends to make the total vehicle/knight height greater than 4 inches. As a result, the larger frontal cross-sectional area of the knight's body is exposed and becomes a source of resistance. The design of the bicycle has been reduced, and the cross-sectional area of the front side exposed by the Cavaliers is reduced compared to those encountered in the bicycle system of the more standard type. Such vehicles are known as reclining bicycles. The design of the reclining bicycle allows the knight to take a recline position during vehicle operation. The reclining bicycle has been designed for the rider to maintain the current short-distance rate recording. Regardless of its success, a reclining bicycle with standard front wheel steering and rear-wheel drive requires a long drive chain placed under the knight. Unfortunately, such drive chains are a potential source of resistance because they tend to increase the height of the vehicle while increasing the front cross-sectional area. According to basic theory and physics, there is no transfer of energy (momentum) when the direction of force applied to an object is perpendicular to the direction of movement. If there is no energy/moving K shift, the object remains in its previous state, such as moving or a certain straight, 'spring motion. Computationally, the energy transfer can be expressed by the force vector, the motion vector, and the cosine product of its forming angle. When the force and motion vectors form a right angle & the cosine of the right angle is zero and the product is zero. When the forces and movements are parallel, the most efficient energy transfer can be achieved. 84670.doc 1277560 In fact, all commercial bicycles are misunderstood, and the system is used. When the circular crank is configured, the thrust generated by the knight's straight position on the safety bicycle will move the pedal position. If the m μ scented board is used and the parallel pedal moves S, the rider can use the double pedal. Ancient gu gu. Rotating π to effectively shift the pedal force for crank rotation and time, about one of the rotation cycles of Qiu Ba / Gu Niu Niu due to the effective power transfer part of the knife rotation cycle is the most difficult, because of the clever ^ LG Shi He The lack of momentum may be lost. For a slanting type of W supervisor, take the 曰 叻 叻. Take the efficient power transfer position, and get the same, but the overall efficiency of the pedal cycle is the same. From the above, you can know the expectation Various obstacles in bicycle design and construction. According to various embodiments, a human ground vehicle may be provided.

The following discussion of the preferred embodiment of the invention will naturally be used as an example only. Therefore, the discussion is not intended to limit the scope of the invention, the application of the invention, or the use of the invention. Referring first to Figure 1, a further preferred embodiment of a human ground transportation vehicle 1 is shown in a side elevational view. The vehicle 10 is equipped with two wheels, one of which is placed behind the other wheel 14 of 84670.doc -15-1277560. This is a universal type of vehicle that is well known (and can be cited in this article) as a bicycle. The bicycle 1 of Figure 1 is described in a fully upright operational form. The reference letter 'L' indicates the approximate distance along the longitudinal axis of the vehicle. This length is for illustrative purposes only and is not meant to be limiting. It is to be understood that the invention is based on the precise construction of the vehicle. Various sizes, shapes, and various dimensions. The illustrated bicycle 10 includes a plurality of basic accessories, such as: a frame 16 that spans the distance between the wheels 12, 14; a seat for the rider to ride 18; a steering handle: a handle 20; And the vehicle-driven pedals 22 and 24 (on the right and left sides, respectively). In short, with respect to vehicle steering, the present invention employs a device for manually rotating the front wheel 14 by means of the handle 20 and the steering column 34 as needed. With respect to vehicle drive, in accordance with the teachings of the present invention, the foot forces applied to the pedals and turns are transmitted to the front wheels 14 via a gear system and chain configuration. The vehicle 10 is distinct in design, configuration, and operation from the bicycle. As mentioned above, most of today's bicycles are turned by the front; &lt; wheels are completed, and the driving (force) of the vehicle is provided via the wheels placed at the rear. On the other hand, the vehicle 10 Various embodiments can simultaneously cause both steering and driving to be effected via the front wheels 14. The difference between the bicycle 10 and the general bicycle is the relationship between the positions of the pedals 22, 24 relative to the position of the seat 18. A force is applied to the area of the pedals 22, 24 from a path extending from the area of the seat 18. The pedals 22 can be disposed at a position along the foremost region of the frame 16 due to various embodiments. 24, therefore, this force is directed toward the front end of the vehicle along the diagonal line. Therefore, this operating force 84670.doc -16 - 1277560 <universal direction' has a substantial horizontal component. Because &amp; During operation of the vehicle constructed in various embodiments, the riding left posture is lowered with a reduced total orientation. This position of the knight can assist in reducing the resistance. This is basically the same as having the pedal on the bottom of the mount knight. The technical bicycle is sharply contrasted. As described earlier, such a bicycle requires a vertical operating force, which tends to place the knight in an upright high resistance operating position. It is intended to provide a component arrangement that not only distinguishes the bicycle 10 from most of the well-known bicycle configurations on the knot, but also reduces the number of bicycles 10 in the process of switching between the upright operation mode and its dense folding form. Various inconvenient possibilities. It is apparent that certain important structural features and advantages of the present invention are apparent from the discussion and description set forth above. When the study is presented below, the detailed description of the body and the reading of various additional comments are provided. Such features and advantages will be more apparent, and further preferred embodiments of the present invention will be readily appreciated and appreciated. The frame 16 outlined in the embodiment of Figure 1 is comprised of a plurality of separate and distinct frame sub-components or regions. In particular, the frame 16 (as shown) includes a front area 26 disposed at the front end of the vehicle 10, a rear side of the vehicle 10, or a rear area 28 of the Ozaki, and an intermediary along the middle of the vehicle 10. The intermediate region 30 spans a spatial distance separating the front and rear regions (26 and 28). Once the alignment regions (i.e., the previous one) are properly sequenced as described in more detail later, the regions (26, 28, and 3) can function as a single frame. The individual regions (26, 28, and 30) of the frame 16 are uniquely adapted to function as components for supporting vehicle-specific accessories. In addition, each region (26, 84670.doc -17-1277560 28 and 30) is purposely shaped to achieve and/or tolerate desired outcomes and goals, some of which are generally independent of the vehicle frame. The structure of Figure 1 can be exemplified as a plurality of frame regions (26, 28, and 30) that are characterized by design, construction, and configuration through a particular structure. The front region 26 of the frame 16 can be used to support the footboards 22, 24 and associated structures as shown in FIG. As also shown, each of the individual pedals 22 is coupled to one of the individual crank arms or levers 33 and 35 (on the right and left sides, respectively). Such a connection desires a form that allows the pedal to rotate. The pedal connection can be obtained by inserting a short pivoting rod that extends from each pedal (22, 24) into an individual socket formed in the outer end region of each crank arm. Next, the other ends of each of the crank arms 33, 3 are connected to make a full angular motion around a different mandrel. The crank arms can be coupled to the frame attachment points 36 (only one of which can be seen in the side view of Figure j) in a manner that each pedal is coupled to the crank arms and can be pivoted about its individual mandrels 36 in a front-to-back fashion. The mandrel 3 6 ' for each crank arm can be placed adjacent to the foremost region of the vehicle while laterally traversing the side surface of the front frame portion 26. The pedals can be coupled via a crank lever 33, 35 to a first gear 8 〇 which is coupled to the roller clutches 37, 38 or means for transmitting a clockwise pedal to the first gear. The movement of the reciprocating pedal arm is limited to 40 degrees from the center position. The central position is substantially vertical to the ground. The direction of pedal movement is substantially parallel to the direction of application of force, allowing for high efficiency (greater than 7〇%) of power transmission. The lever members 33, 35 may include at least one biasing member that biases the lever member in the rearward direction of the vehicle. The offset element can be a spring. For example, the offset element can generate a pressure of about 3 to about 5 pounds against at least one of the rods 33, 35. 84670.doc -18 - 1277560 0 rods 3 3, 3 5 can simultaneously be a jie a front w=r In front. When the levers 33, 35 are moved toward the car, the vehicle is pushed forward. Moving the lever members 33, 35 toward the vehicle (four) side will interfere. Or the father of the father interferes with or hinders the forward movement of the vehicle... The double board allows the knight to propel the vehicle but uses a substantial changer Shao Nandu. The difference between the maximum and minimum height of the foot is the circle of the outer diameter of the crank (between 12 and 15 )), and the Xuan's 曰 曰 y y motion pedal is different, the reciprocating pedal capacity = the minimum height The difference between the two is less than clever. In the prior art device, the slanting slanting of the short-wheel base is a reclining posture. The reciprocating pedal design allows the knight to take almost any desired sitting position. Or a mixture of the four (four) bearing, π to fix the rotating shaft of the gear pedal. Two bearings separated by a distance greater than w, can reduce the bending resistance caused by the uneven load due to the pedal action. The maximum applicable distance-separated bearing 'can be used to minimize the stress associated with bending. The front area 26 additionally provides support for certain other accessories, which may include: - a gear train that forms part of the vehicle drive system; a connecting element of the vehicle swivel arrangement 34; and a connecting element at an area where the front block body area % contacts the intermediate frame area 30. The transmission component of the reciprocating pedal assembly includes pedals 22, 24 and crank levers 33, 35. In order to achieve a higher power transmission effect, a reciprocating pedal assembly can be used instead of the circular pedal assembly. One-way rotation of the first gear 80, roller clutches 37, 38 (on the right side 84670.doc -19-1277560 and on the left side, respectively) are used to ensure that the first gear 8 〇 will only be in the clockwise direction (viewed from the left side of the vehicle) Rotation, so that the vehicle can be magically pushed by the forward movement of the crank levers 33, 35, and when the crank levers 3 3, 35 are moved back toward the rear of the vehicle, there is little or no continuous hindrance to the forward movement of the vehicle. The roller clutch can be built into a sprocket, wheel or wheel bearing assembly that allows the rut or add-on assembly to freely rotate in one direction while countering the gear or wheel movement in the other direction. For example, a pedal assembly including two pedals, a crankshaft, and a sprocket can generate power when moving in a direction by locking the crankshaft toward the sprocket, and the crankshaft can freely rotate in the opposite direction. One tooth The second gear 90 is engaged with the second gear 90, which will rotate only in the counterclockwise direction. The first gear 9 is fixedly coupled to the first gear 86, and the second gear 卯 is rotated together with the first sprocket 86. The pedal below %, the power stroke is in the clockwise direction. The gear money can be - the effective direction of the reverse rotation is 4, so that the two gears 8〇, 9〇 are the minimum components needed to change the direction of rotation. All subsequent power The transmission configuration can be obtained by using a chain, which can maintain the rotation direction. The outer diameter of the first gear 8 can be larger than the outer diameter of the second gear, and the higher the rotation rate of the wheel can be achieved. The middle portion of the frame 16 is 3〇, The front region 26 can be joined at an upper point 4 〇 and at a lower point 42. The connection point 4Q, like the two frame regions 26, 30, is arranged at the area where they meet. Although any suitable connecting means can be employed, the present invention desirably connects the points 4G, 42 - a frame-turning connection element can be utilized to allow the frame area to rotate relative to the other area. The mandrel for this L rotation can be placed in contact. The rotating frame shaft is placed at the joint point 4〇, which provides an extremely efficient structure in order to obtain a close-knit 84670.doc -20-1277560 state when the bicycle 10 is folded. With this configuration, a substantial overlap between the frame regions (26, 3) can be obtained when a frame region is folded around the other frame regions. If the point of rotation 40 is a potential source of structural problems within the frame 16, it may be desirable to construct an area that is as reasonably enlarged as possible to enhance the strength of the frame. The structural features and configurations described above assist in providing a structure that allows for the folding size of a small vehicle. As shown in the embodiment of Fig. 1, the seat cymbal 8 is supported by a portion of the frame cymbal 6. While the seat 18 can be coupled along the top side of the intermediate region 3 (as shown), it is contemplated herein that in some instances, the seat 18 can be attached to the top end of the rear block region 28. Any known connector device that is deemed appropriate by the skilled artisan can be used to effectively connect the seat 18 along the frame 16. One type of configuration that is expected in this paper is to use a rod that is fastened to the seat at one end and to the socket of the vehicle frame at the other end. Such a connecting element can also provide a socket arrangement that can be used to adjust the seat position between various predetermined positions. The top side of the intermediate portion 30 can have the same spacing opening for the attachment of the seat so that the seat can be connected to different sets of openings while being placed in a position most suitable for the length of the knight's foot. The seat pine 18 can also be used as a carrier. The lower portion 18a of the seat 18 and the upper portion 18b of the seat 18 can be connected by a hinge 21. The lower portion may include rollers 141, 142 for moving the folded carrier over the paving surface, and fixed and telescopic rods for attaching the seat; hr to the intermediate portion of the frame. Roller 200 may be placed in the seat/carriage, as needed, or in addition to or in addition to one or more rollers 141, 142, while further moving the plucked vehicle ίο over a piece of Laying or unpaved areas.

In the operating condition, the space behind the back pad 145 can be used as the storage space 154. The hinge 148 can be mounted to provide easy storage of the storage area 154 via the storage cover 147. From the side view, the lower and upper parts of the cargo box have a triangular shape. This selected shape allows the load box to be, for example, about 9 inches in length, without adding the height of the middle portion of the knight mount during the operational state. The carrier can have a handle for ease of use. The handle can be placed in the cargo compartment, making it easy and convenient to roll the cargo compartment on the ground. The rear frame body region 28 includes a suitable structural bracket following the rear vehicle region, which can store the rear wheel 12. In particular, the rear region 28 provides a device structure that is adapted to support the rear wheel 12. Therefore, the rear wheel 12 can be freely rotated about its central axle 13 by being mounted. According to such an embodiment, the rear wheel 12 can follow the front wheel 14 at any time during travel. The rear region 28 can also include a damping strut 5G having a - first end and a second end. The individual ends of the shock absorbing strut 5' can be connected at the axle 51 to form a rigid connection "upper portion of the rear area 54" while the wheel joint block 55 is connected at the axle 52. The wheel connection block 55 can also be joined at the lower portion of the rear region 28 after the rigid connection at the axle 53. A through hole located in the intermediate portion 3 () and a through hole 48' located in the rear region 28 can be used to fasten the connection of the two regions. A sliding element (4) is used to tighten the through material (10) when the two fields are rotated to the operation (4). 84670.doc • 22- 1277560 After the bicycle 10 is folded, the rear area 28 can be further adapted to rotate in the form of the best σ degree. This rotation can be made about the axis 46 of the vertical alignment which allows the rear region 28 to sway laterally outward and around. In the various embodiments of FIG. 1, the single full length caused by the rear region 28 is laborious (ie, starting from an extreme point, continuing until reaching the other extreme point), rotating at an angle of about 180. Degree angle. Thus, the rear region 28 can sweep a sufficient angular distance to reach a preferred final position that abuts the intermediate region 30 while generally paralleling the generally vertical plane of the intermediate region 3〇. This structure also assists in ensuring the smallest vehicle fold size. Referring additionally to Figure 2, various embodiments of the intermediate region 3〇 and the rear region 28 are shown. The component side connecting the intermediate portion 30 to the rear region 28 may include two double articulated joints 46, 47. The other side may include a sliding member 48. The sliding member 48 is adapted to be activated by a locking pin 49 that is rotatable about the mandrel 46. The lock pin 49 is normally locked in its lower position unless the vehicle is folded or deployed. The sliding member 48 and the crank lever 49 are provided with teeth for obtaining a tightened crank lever position. The sliding element is operable to engage the hinges 51, 52 that are rotatable about the mandrels 53, 54 located rearward of the intermediate portion 30 of the frame. The rear region 28 can be shaped as a lower map region 55. It is expected that steel, aluminum, alloy or fiber reinforced plastic resin can be used. Of course, any other material that is considered suitable by the skilled person can be used as a frame structure. Non-slip bolts or other suitable components may be used to secure and maintain the vehicle frame area for deployment in accordance with various embodiments. Similarly, a suitably folded positioning latch at point 65 can be used to secure and maintain the vehicle in its folded configuration. 84670.doc •23- !277560 A general folding bike that reduces its full length and full height can be executed as follows. First, any component used to interlock the zones with each other is released from the compacted form. In order to cause the first folding, the rear region 28 of the frame can be rotated to the left with respect to its associated vertical axis, so that the rear region 28 and the intermediate region 3 of the frame are finally parallel to each other. The second fold can be obtained by rotating the front frame region 26 relative to its associated horizontal axis such that it substantially overlaps the frame intermediate region 30. The seat 18, the footrests 22, 24, and the handle 20 can be transferred from a single operational position to a storage position. It has been folded and the bicycle is 1 〇, which can be conveniently carried and/or stored (such as placed in a passenger train, bus, van, airplane or other mass transit seat). The folded vehicle 10 can be stored in a carrier formed by the upper portion of the seat 18 and the lower portion 18a. According to various embodiments, the front steering strut 34 can include front wheels 14 (including the front tires), drive chains 102 and 103, handles 2, and other control devices such as brake and gear shifting elements that are not specifically shown. The steering column 34 can be connected to the front frame area by two (or more) bearings such as an upper bearing and a lower bearing. The width of the front frame region 26 is substantially reduced along the area adjacent the steering column 34 to properly accommodate the steering struts. The steering column 34 is adapted to be overlaid on top of it. Special folding and unfolding can be modified to meet different needs based on the height of the knight and/or any other particular preferences. The top of the steering column, the _ hole six crepe keys, such as the hinge shaft 76, the front hinge 79, the rear hinge 78, the standing pillars _ hand grips 67 and 68 (right hand and left hand). The rear hinge 78 is permanently connected to the upright post 84670.doc -24-1277560 at the mandrel 70. The top plate 62 can be permanently attached to the front and rear hinges at the mandrels 76 and 73, respectively. The rear hinge includes three axes 70, 71 and 72. The upright support comprises two axes 70, 71. In the folded position, all of the elements are at the same level as the outer handles 67, 68, the upright posts 69 on the inside of the handle, the front hinge 79, the rear hinge 78, and the top block 62 in the middle. According to various embodiments of the assembled configuration shown in Figure 6, the front hinge 79 rotates about the mandrel 76 and the rear hinge 78 rotates about the mandrel 73 such that the mandrels 91, 71 and 72 are aligned and locked to each other. The handle can be rotated outwards. The steering column 34 is rotatable relative to the front frame region % along a rotational axis that extends beyond the center of the upper bearing 63 and the center of the lower bearing 64. Angular rotation can be limited. For example, the angular rotation can be limited to less than about 35 degrees. Unexpected Cavaliers will suffer significant inconvenience due to reasonable restrictions. Figure 3 is not generally indicated by reference number 59. In the vehicle 〇 linkage structure. The link 59 can be arranged along the wheel 14 as well as the bearing 63 and the material. The connecting rods may be constructed and arranged generally in the form of a drive train, chain 1 () 2 as described above. The construction and swing of the link 59 provides the appropriate structural strength with a minimum folded vehicle width. Looking forward, the clutch, the pedal of the front tire. It can be arranged at the wheel 14

Used to achieve this purpose. Arranging a ratchet device or roller at 4 will not cause the chain 103 to be unintended. Any known arrangement can be

pedal. Some known bicycle devices, &lt;foot pedals. The pedal placed in front, with the foot placed below the %, having a position generally placed in front of the knight can be used in accordance with various embodiments for this 84670.doc -25-1277560 text because it allows the knight to be lower The position has a reduced total height. The foot pedals 22, 24 shown in Fig. 1 are adapted to rotate about a mandrel placed in front of the steering column 34. The reciprocating pedals that are swept back and forth are more preferred than the conventionally used rotary pedals because they reduce the need to lift the foot H. However, the rotary pedal can coexist with the essence of the present invention. According to the pedal of the present invention, a sufficient distance (crossing the longitudinal centerline of the bicycle) is separated from each other to allow the front wheel to rotate unimpeded. A human (foot) force is applied to the pedals 22, 24 which cause the individual crank arms 33 to be fixed relative to the front frame region 26 to be rotated about 14%. The crank arms μ, 35 are arranged in mechanical communication with the gears to induce rotation of the gear 80 in response to the cranking action. According to various embodiments, the power stroke occurs in a clockwise direction. In order to rotate the gear 8〇 following the power (four) direction, the configuration of the one-way ratchet or roller clutch can be used to allow the ratchet or roller clutch configuration to be used only for the universal movement of the wheel, which can be tolerated when the pedal is only When pushing forward, each foot pedal is connected to the drive mechanism. In the middle pedal will slide freely relative to the drive gear. By this configuration, it is transferred to the second use: the pedals 22, 24 are moved in front of and behind the circular traveling fan. == Any known ratcheting phrase that is suitable for the skilled person to consider is applicable to the present invention to achieve this goal. Now explain the structure to ensure the period of 24...1:: for the power pedal 22, the knight wants (4);: (4) the board can be used when the pedal 22 is pushed forward, the final crank arm 33 moves, the lure Gear 84670.doc -26- 1277560 8〇 rotates in the clockwise direction. The gear 8G and the gear 9G are mechanically coupled to each other to induce the gear 9G to rotate in response to the action of the gear 8 。. The gear sun gear 90 is cooperatively configured to rotate the gear (10) in the counterclockwise direction. Next, the gear 90 and the sprocket 86 are in direct mechanical communication arrangement for inducing the sprocket 86 to rotate in response to the action of the gear 90. The wheel 9 and the key wheel % can be configured such that the sprocket 1G7 rotates in the counterclockwise direction. Gear % and: Wheel % can be fixed and when the gear 90 rotates, the sprocket 86 also rotates in the same direction. The gear used in the present invention is preferably made of a high strength material such as steel. Any other material that is considered suitable by the skilled artisan can be used in the gear construction. According to various embodiments, an intermediate power transmission assembly, as shown and described, includes a universal joint connector. According to various embodiments of Figures 4 and 7, the intermediate power transmission assembly includes a gear 1 〇 6 including a sprocket 1 〇 7 by a universal joint nipple and a second including an annular member 108 The sprocket 122 is in mechanical communication. The gears 106 are in communication and are powered by the gears 86 of the moving power input assembly by the chain 1〇1 and the sprocket 1〇7. The sprocket 122 is in communication and is powered by a chain 102 to the rotatable sprocket 74 of the front wheel. The universal joint connector shown in Figure 7 can be connected directly or indirectly to the foot pedal to provide a power input. Gear 106 can be fixedly positioned for rotation within front frame portion 26. A large through-hole bearing 丨 25 mounted on the frame 26 contacts the gear 丨〇 6 and prevents movement of the gear relative to the frame except for the rotational movement. The large through-hole bearing allows rotational movement of the gear 106 about the axis of rotation 128. The inner ring projection 126' of a bearing ι25 is parked in the corresponding groove and recess 127 formed on the outer surface of the gear 1〇6 while preventing lateral and longitudinal movement of the gear 106 relative to the vehicle frame. Axis 84670.doc -27- 1277560 The carrier 125 can be mounted to the frame portion 26 by any of a variety of means, such as by screws, 糸, adhesives, friction fits, or narrow brackets. The gear 106 includes a sprocket 1〇7 which has a built-in chain 1〇1 and is capable of transmitting power from the gear to the gear 1〇6. The gear 106 is in the shape of a circular tube having a hollow central portion in which a ring member 108 is built to form a partial universal joint connector. While other universal joint connectors&apos; may be considered in the field of various embodiments, the universal joints illustrated may be employed. The universal joint connector 1 〇 5 shown in Fig. 7 includes a gear yoke 6, an annular member 108, and a sprocket 122 rotatable on the axle 120. When the knight applies the vehicle in a straight forward direction, the axle 120 of the sprocket 122 rotates with the gear 106 about the rotational axis 128, and the sprocket 122 rotates in a plane parallel to the plane of rotation of the front wheel. Therefore, when the chain 102 transmits power from the sprocket 122 to the sprocket 74 of the front wheel, no torque is introduced into the chain 102. During the rotational movement of the vehicle, the axle 120 rotates about a rotational axis that is offset relative to the rotational axis 128, but the sprocket 122 continues to rotate in a plane parallel to the plane of rotation of the front wheel, which again is not torqued into the chain 102. According to various embodiments, at least one sprocket or at least one sprocket assembly may or may be replaced by a derailer system having a plurality of sprocket wheels for adjusting the degree of impedance required to rotate the human vehicle ground drive wheel. The derailer system can include at least two sprocket wheels that are fixedly coupled to one another, and one or more smaller sprocket wheels, metal wires, offset devices, adjustable chain tensioners, and/or a chain that can be moved from a sprocket The assembly of the guide to the other sprocket. A human ground vehicle can contain more than one derailer system. For example, in a sprocket assembly incorporating a derailer system, the sprocket 122 can be replaced or can additionally include a plurality of 84670.doc • 28-1277560 sprockets. The derailer system can be mounted to the wheel 14. The derailer system can replace the sprocket 74. The vehicle is preceded by the members 58 and 59 or the rigid arms that are rigidly attached to the front wheel axle (not shown) in such a manner that the front wheels are rotated on the axle. The axle 120 of the sprocket 122 is rigidly attached to the forks 58 and 59 on either the opposite side or the same side of the sprocket 122 in a manner that allows the axle 120 to rotate. As the steering strut 34 rotates about a rotational axis, the front resilience members 58 and 59 also rotate about the same mandrel due to their rigid connection to the steering strut. Similarly, the axle 12 and the sprocket 122 also rotate about the same mandrel as the steering strut 34 rotates due to the connection between the fork members 58, 59 and the axle 12 . The right and left 59 and the left and right forks 58 of the steering column 34 may include spring absorbing strut 92, 93 (right and left). The front wheels can be attached to wheel connection blocks 95, 96 (right and left). The end of the shock absorbing strut can be attached to the fork and the wheel connection block (59 to 95, 5 8 to 96). The positioning of the chain 1〇3 allows vertical movement of the wheel 14 and the shock absorbing strut without disturbing the rotational movement of the chain 1〇3, the sprocket 74 or the sprocket 220 rotatably fixed to the wheel 14. The universal joint connector can function as follows. The gear 1〇6 may have two inner convex bearings 109, 11〇 which are integrally formed with each other or otherwise mounted on the inner ring surface of the gear. The bearing can also be introduced into the through hole of the outer surface of the gear 1〇6 and protruded into the inner surface thereof and fixed by welding, honing, adhesive or other methods. The bearings 109, 11 〇 can extend from the inner wall surfaces of the gears 1 〇 6 into the recesses or core holes 129, 13 穿过 through the outer wall surface of the annular member 108, respectively. Although the embodiment may have a core hole for receiving the bearings 1 〇 9 and 110, it may be appreciated that a recess may be employed instead of the through hole to have a built-in bearing. 84670.doc -29- 1277560 The key wheel 122 and its axle 120 are contemplated as part of an intermediate power transmission assembly that may also include an annular member 108 and a gear 106 in accordance with various embodiments. The sprocket 122 transmits power to the sprocket 74 from the intermediate power transmission assembly by the chain 1〇2. The sprocket 122 can be driven by the axle 120, the axle 120 can be driven by the projections or bearings 112, 113, the projections or bearings 112, 113 can be driven by the annular member 1 〇 8 and the annular member 108 can be driven by the gear 1 〇 6. Therefore, when mechanical force is supplied to the power input assembly, power is transmitted to the front wheels via the intermediate power transmission assembly. The sprocket 12 2 can be rigidly coupled to the axle 12 俾 to rotate therewith. The axle 12 is rigidly connected to the projections or bearings 112, 113. When the bearings 112 and 113 rotate about the axis of rotation of the axle 12, their transmission rotationally moves to the axle 12, and then the transmission rotates to the sprocket 122. As shown, the axle 120 can be provided with an enlarged portion 121 having a cylindrical opening therethrough for a sufficiently large diameter to incorporate bearings 112, 113. According to this embodiment, the bearings 112 and u 3 are each made of a single cylindrical metal block or metal bar such as steel. The rods constituting the bearings 112, 113 have an outer diameter which is only slightly smaller than the diameter of the cylindrical opening portion 121. Therefore, a suitable fit of the rod within the opening is provided. The rods can then be welded in the opening to secure them, or they can be bonded or deformed by other bonds. A retaining screw can be used to secure the rod within the opening as long as the rigid connection of the bearing 112, ι 3 to the axle 120 is achieved. If the rod is tightly fitted in the mouth, it does not need to be welded or otherwise fastened to the rod. Alternatively, if the bearings ι 2 and 113 are directly welded to the axle 12 , or integrally formed therewith, or if the other foot is rigidly coupled to the axle, the enlarged portion of the axle may not be required. The rotation of the bearings 112 and 113 can be driven by the rotation of the ring member 1〇8, and the connection f is driven by the rotation of the gear 106. The bearings 112 and 113 can be placed in the pockets or bores 132, (1) of the ring member 1G8 of 84670.doc -30-1227560, respectively. While the various embodiments show reference numerals 132, 133 indicating through-holes that completely traverse the wall of the annular member 1 〇 8, it is understood that the recess can be used in place of the through-hole to incorporate a bearing. The relationship between the bearings 112, 113 and the core holes 132, 133, respectively, allows the bearing to be confined within the bore, but can remain sufficiently loose within the bore to permit pivotal movement of the bearing. The bearings 112, 113 and the axle 12 〇 can be allowed to pivot about a mandrel that is defined to simultaneously pass through the centers of the bearings 112 and 113 and substantially perpendicular to the axle 12 〇 and the mandrel. Similarly, the bearings 1〇9, 11〇 can be defined within the bore 129 130, respectively, but remain loose enough to permit pivotal movement of the ring member 108 on the bearing. Thus, the annular member 108 can be allowed to pivot about a mandrel defined to simultaneously traverse the center of the bearings 109, 11 and pass through the center of the core holes 129, 13 . As a result, even though there is an oblique relationship therebetween during the rotation, the universal joint connector allows sufficient effective transmission force to be transmitted from the motion input assembly to the front wheel. According to various embodiments, the core holes 129, 130, 132, 133 may be much larger than the bearings 109, 110, 112, 113, respectively, and the sleeve bearing, the lining, the needle roller bearing or other anti-wear device may be configured Between the bearing and the heart hole. In various embodiments, the axle 12〇 diameter may be greater than the diameter of the bearings 112, U3. When the axle 12 diameter is smaller than the diameter of the bearings 112, 11 3, more power may be tolerated in less product. If the bearings 112, U3 are configured as a single bar that extends over the wheel, it may also be necessary to have a larger diameter axle 120. In order to construct a universal joint connector, an assembly method involves providing more than one annular member such as two semi-circular members. The annular member 108 can include two semicircular members 140, 141 that are secured by screws 142. If the bearings 1〇9, 110 8467〇.d〇c -31 - 1277560 are pressed through the wall of the gear 106 and directly enter the core holes 129, 130, respectively, the annular member may not necessarily be divided into semi-circular members. However, one or more detachable regions of the annular member may allow the bearings 112, 113 to enter the bores 132, 133, respectively. 0 If the bearings 112, 113 are configured to extend over a single rod at the location 121, then The wheel shaft 120 can be inserted into the ring member 1 without disassembling the ring member, then the rod member can be inserted into the core hole 32, the opening at the wheel portion 丨2丨, and the hole 133 can be inserted. If the bearing 1〇9, u〇 is pushed over the inner hole of the gear 1〇6, it can also be inserted into its individual core hole without disassembling the annular member 1〇8. Therefore, the annular member 1〇8 can be provided as a A single piece that needs to be assembled or disassembled. It should be understood that both the two-wheel and three-wheel embodiments can be constructed using various embodiments. The above-mentioned "vehicle frame area can be known by processing the inscription material (such as a block piece) in a kilogram. It is of course desirable to construct a vehicle of the present invention using a low cost production technique suitable for the selected materials. Casting, forging, forging, and/or welding are all considered appropriate production techniques. Forging may be suitable for this month &lt; plastic structural components.
