Abstract

The present invention relates to a dual riding and driving tricycle in juxtaposing link, particularly to one that can be pedaled by two riders in side-by-side coordination so that the riders and the tricycle will incline integrally without tumbling or overturning. At least one articulation mechanism is disposed between a primary bicycle body and an auxiliary bicycle body, wherein the articulation mechanism serves in synergy an articulation parallelogram and a resilient tension mechanism counteracts the deformation of the articulation mechanism to maintain equilibrium. A front wheel and a rear wheel of the primary bicycle body and an auxiliary wheel of the auxiliary bicycle body form a triangular area, and the riders' center of gravity of the dual riding and driving tricycle is within the triangular area, which keeps the riders and the tricycle stable without any possibility of tumbling.

201004835 六、發明說明：【發明所屬之技術領域】本發明係關於一種腳踏車，詳言之，係關於一種並聯式腳踏車。【先前技術】腳踏車是一種相當普遍大眾化的人力式交通工具。取所皆知雙輪腳踏車在靜止時，是完全不穩定的，必須靠乘騎者的腳來維持平衡。由於物體本身的慣性，當腳踏車轉彎; ® 時，慣性使得車趙依照原來的方向行進，若重心過高、車速過快或轉弩太急，即使摩擦力足夠提供轉弩時所需的向心力’但是轉弩時對質心所產生的力矩，也會使得車體旋轉而翻倒。而雙輪腳踏車行進轉弩時，可藉由人體與車體的傾斜，以產生反方向的力矩，來減少由摩擦力所造成向外翻倒的力矩。基於此種原理及現象，雙人腳踏車自然就比三輪或四輪車輛行駛時更為穩定。目前，已有一種並騎式腳踏 ^ 車，但該種腳踏車為單一車體，在車體上設置前、後串聯式的座椅’以供雙人協力乘騎。另外，亦有以固定杆將兩個獨立車链聯結’以達到平行並騎的效果，但此種以固定 • 杆聯結方式完成的雙車體屬於速度頗慢的幼童學步車，僅能供幼兒學步使用。若是採用可較快速乘騎的腳踏車且利用固定杆將二平行並列的腳踏車相聯結，在遭遇路面高低不平或是轉彎時均無法讓聯結車體保持穩定，更有可能導致翻覆的危險。 140423.doc 201004835 因此’有必要提供一創新且富有進步性之並聯式腳踏車，以解決上述問題。【發明内容】本發明提供一種並聯式腳踏車，其包括：一主車體、一副車艘及至少一關節式機構。該主車體具有一主車架本艘、一前輪、一後輪及一腳踏機構，該前輪及該後輪相隔一距離樞設於該主車架本體，該腳踏機構用以驅動該前輪或該後輪。該副車體具有一副車架本體及一副輪，該副輪樞設於該副車架本體。該關節式機構具有一第一端、一第二端及至少二連桿，該第一端及該第二端分別連結該主車架本體及該副車架本髏，該等連桿實質上平行地連接於該第一端與該第二端之間，該第一端、該第二端及該等連桿構成一可活動之四邊形。综觀本發明之並聯式腳踏車，其係可相互平行並列騎乘且能各自單獨踩踏，並藉著該關節式機構連結該主車髋及副車體，不僅提供平行並騎腳踏車的休閒娛樂效果，更提供了行進時更穩定且不會翻倒車體的使用優點，此外，因該副車體之結構精簡’故可減少成本並容易進行維護。再者’該關節式機構即可再精簡化而降低成本，以符合經濟效益。【實施方式】201004835 VI. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a bicycle, and more particularly to a parallel bicycle. [Prior Art] A bicycle is a very popular humanized vehicle. It is well known that a two-wheeled bicycle is completely unstable when it is at rest, and it must be balanced by the rider's foot. Due to the inertia of the object itself, when the bicycle turns; ®, the inertia makes the car Zhao travel in the original direction. If the center of gravity is too high, the speed is too fast or the speed is too fast, even if the friction is enough to provide the centripetal force required for turning. However, the moment generated by the centroid when turning, will also cause the car body to rotate and fall over. When the two-wheeled bicycle travels and turns, the human body and the body can be tilted to generate a torque in the opposite direction to reduce the moment of tipping over caused by the frictional force. Based on this principle and phenomenon, a tandem bicycle is naturally more stable than a three- or four-wheeled vehicle. At present, there is a type of riding bicycle, but this type of bicycle is a single body, and the front and rear series seats are arranged on the vehicle body for the two people to ride together. In addition, there are also two independent chains that are connected by a fixed rod to achieve parallel and riding effects. However, the double body that is completed by the fixed rod connection is a slow-moving young toddler. For toddlers to use. If a bicycle that can ride faster is used and the two parallel parallel bicycles are connected by a fixed rod, the joint body cannot be stabilized when encountering unevenness or turning, which is more likely to cause overturning. 140423.doc 201004835 Therefore, it is necessary to provide an innovative and progressive parallel bicycle to solve the above problems. SUMMARY OF THE INVENTION The present invention provides a parallel bicycle that includes a main body, a sub-vehicle, and at least one articulated mechanism. The main body has a main frame, a front wheel, a rear wheel and a footrest mechanism, and the front wheel and the rear wheel are pivotally disposed on the main frame body at a distance, the pedal mechanism is used to drive the Front wheel or the rear wheel. The sub-body has a frame body and a pair of wheels, and the sub-wheel is pivotally disposed on the sub-frame body. The joint mechanism has a first end, a second end and at least two links, the first end and the second end respectively connecting the main frame body and the sub-frame body, the links are substantially Connected in parallel between the first end and the second end, the first end, the second end and the links form a movable quadrilateral. Looking at the parallel bicycle of the present invention, which can be parallel and juxtaposed in parallel with each other and can be stepped on by each other, and the main vehicle hip and the sub-body are connected by the joint mechanism, which not only provides parallel and cycling entertainment effects. It also provides the advantage of being more stable when traveling and does not overturn the vehicle body. In addition, because the structure of the sub-body is simplified, the cost can be reduced and maintenance can be easily performed. Furthermore, the articulated mechanism can be simplified and reduced in cost to be economical. [Embodiment]
