    • A removable bicycle beam for adapting a bicycle frame for engagement with a vehicle-mounted bicycle rack. The beam includes a pair of securing mechanisms disposed on opposite ends of a central body. Each securing mechanism includes a fixed arm fixedly secured to the central body and a pivoting arm pivotally secured to the central body. Each arm includes a gripping portion extending outwardly from the central body that cooperates with the gripping portion of the other arm to releasably encircle and engage a component of the bicycle, such as the handle bar stem or the seat post. The pivoting arm and fixed arm lie in a substantially horizontal plane when in a closed position, and the pivoting arm is movable in the horizontal plane toward and away from the fixed arm. Each pivoting arm can be locked in a closed, engaged position by one of a pair of releasable latch mechanisms disposed within the central body and engagable with the pivoting arms. The central body is formed of a pair of telescopically mounted tubes that enable the beam to shift the securing mechanisms with respect to one another in order to accommodate bicycles having various lengths between the handle bar stem and the seat post.
    • 一种用于适配自行车车架以与车载自行车架接合的可拆卸自行车梁。 梁包括设置在中心体的相对端上的一对固定机构。 每个固定机构包括固定在中心体上的固定臂和枢转地固定在中心体上的枢转臂。 每个臂包括从中心体向外延伸的抓握部分,其与另一臂的抓握部分配合以可释放地环绕并接合自行车的部件,例如手柄杆杆或座杆。 当处于关闭位置时,枢转臂和固定臂位于基本上水平的平面中,并且枢转臂可在水平面中朝向和远离固定臂移动。 每个枢转臂可以通过设置在中心体内并与枢转臂接合的一对可释放的闩锁机构中的一个锁定在闭合的接合位置。 中心体由一对可伸缩安装的管形成,使得梁能够相对于彼此移动固定机构,以便容纳在把手杆杆和座椅柱之间具有各种长度的自行车。

    • A vehicle with a pedal drive, such as a bicycle, tricycle or moped, includes a frame. A pedal drive is rotatably mounted on the frame and includes a driving gear. A wheel is rotatably mounted on the frame and a driven gear is jointly rotatable with the wheel and includes driven gear teeth. An endless toothed belt is trained about and interconnects the driving and driven gears and includes transmission gear teeth. The driven gear teeth of the driven gear are slightly reduced with respect to driven gear teeth which would correspond to the transmission gear teeth of the endless toothed belt. The frame includes a pedal shaft bearing, a saddle tube extending upwardly and slightly rearwardly from the pedal shaft bearing, a lower frontward frame tube extending upwardly at at an inclination frontwardly from the pedal shaft bearing, a steering sleeve secured to an upper end of the lower frontward frame tube, and a connecting structure extending between the steering sleeve and the saddle tube upwardly of the lower frontward frame tube. A reinforcing beam extends between respective lower regions of the saddle tube and of the lower frontward frame tube and has a first and a second end connected to the saddle tube and to the lower frontward frame tube, respectively, by respective insertion sleeves.
    • 具有踏板驱动器的车辆,例如自行车,三轮车或轻便摩托车,包括一个框架。 踏板驱动器可旋转地安装在框架上并且包括驱动齿轮。 轮子可旋转地安装在框架上,从动齿轮与车轮共同旋转并包括从动齿轮齿。 无齿齿形皮带训练有关驱动齿轮和从动齿轮的互连,并包括传动齿轮齿。 从动齿轮的从动齿轮齿相对于对应于无端齿形带的传动齿轮齿的从动齿轮齿稍微减小。 框架包括踏板轴轴承,从踏板轴承向上向稍微向后延伸的鞍形管,从踏板轴轴承向前倾斜向上延伸的下部前框架管,固定到踏板轴承的上端的转向套筒 下侧框架管,以及在下侧框架管的上方在转向套筒和鞍形管之间延伸的连接结构。 加强梁在鞍形管和下部前框架管的相应的下部区域之间延伸,并且分别具有通过相应的插入套筒连接到鞍状管和下部前侧框架管的第一端和第二端。
