    • The seating arrangement of the present invention comprises a series of hingedly connected rigid platforms with a series of folding seats affixed to selected platforms. Beneath each series of folding seats are a series of hingedly connected folding panels connected to front and rear support frames. When collapsing the seating arrangement for storage, the seats are folded to their closed position and the folding panels fold inwardly, pulling the front and rear frames towards each other. The folding panels may be simultaneously folded by utilizing a member connecting one or more of these folding panels. Additionally, means may be provided for facilitating the collapsing of the seating arrangement from its use position to its compact, folded configuration.
    • 本发明的座椅装置包括一系列铰接连接的刚性平台,其具有固定到所选平台的一系列折叠座。 每个系列折叠座椅下面都有一系列连接到前后支撑框架的铰接式折叠板。 当塌陷座位装置进行存放时,座椅被折叠到其关闭位置,并且折叠面板向内折叠,将前框架和后框架朝向彼此拉动。 可以通过利用连接这些折叠面板中的一个或多个的构件来同时折叠折叠面板。 另外,可以提供用于促进座椅装置从其使用位置到其紧凑的折叠构造的折叠的装置。

    • This invention relates to an improved lever driven bicycle including a shifting mechanism for controlling a drive ratio between the oscillating lever and the drive wheel. The drive lever arrangement may be located about the front or rear wheels of the bicycle and, when about the rear wheel, may include a sole lever or dual levers. The drive lever arrangement includes a drive lever, a force applicator, a shifting mechanism, and a force converter which together transform the oscillating displacement of the lever to a rotation of the drive wheel. The shifting mechanism includes a slide block located about the lever which engages with the drive lever upon downward motion of the drive lever and controllably slides along the drive lever upon upward motion of the drive lever. The position of the slide block corresponds to a drive ratio between the drive lever and the drive wheel.
    • 本发明涉及一种改进的杠杆驱动自行车,其包括用于控制摆动杆和驱动轮之间的驱动比的换档机构。 驱动杆装置可以围绕自行车的前轮或后轮定位,并且当围绕后轮时可以包括底杆或双杠杆。 驱动杆装置包括驱动杆,力施加器,换档机构和力转换器,它们一起将杠杆的摆动位移转换成驱动轮的旋转。 换档机构包括位于杠杆附近的滑动块,当驱动杆向下运动时与该驱动杆接合,并且在驱动杆向上运动时可沿着驱动杆滑动。 滑动块的位置对应于驱动杆和驱动轮之间的驱动比。
