    • The invention relates to a bottom bracket assembly (1) of a bicycle, comprising a shaft (2) having an axis (X-X) extending along a longitudinal direction, a pair of crank arms (30, 40), each one associated with a respective end portion (3, 4) of said shaft (2), a pair of bearings (31, 41) adapted to support said shaft (2) in rotation with respect to a housing box (10) of the bottom bracket assembly (1) provided in a bicycle frame, adjustment means (8) for adjusting the axial position of at least one crank arm of said pair of crank arms (30, 40) with respect to said pair of bearings (31, 41). The adjustment means (8) are axially arranged between said at least one crank arm of said pair of crank arms (30, 40) and a respective bearing of said pair of bearings (31, 41) and comprise a first service ring nut (8a) in axial abutment with said respective bearing (31, 41), a second service ring nut (8b) coupled with said first service ring nut (8a) and in axial abutment with said at least one crank arm of said pair of crank arms (30, 40), and means (8c) for blocking the axial position of said second service ring nut (8b) with respect to said first service ring nut (8a). The first service ring nut (8a) comprises an external threading (8a1) and the second service ring nut (8b) comprises an internal threading (8b1) engaged with said external threading (8a1).
    • 本发明涉及一种自行车的中轴组件(1),包括具有沿着纵向方向延伸的轴线(XX)的轴(2),一对曲柄臂(30,40),每个曲柄臂分别与相应的曲柄臂 所述轴(2)的端部(3,4),适于支撑所述轴(2)相对于所述中轴组件(1)的壳体箱(10)旋转的一对轴承(31,41) 设置在自行车车架中的用于调节所述一对曲柄臂(30,40)中的至少一个曲柄臂相对于所述一对轴承(31,41)的轴向位置的调节装置(8)。 调节装置(8)轴向布置在所述一对曲柄臂(30,40)的所述至少一个曲柄臂与所述一对轴承(31,41)的相应轴承之间并且包括第一维修环形螺母(8a )与所述相应轴承(31,41)轴向邻接;第二服务环形螺母(8b),其与所述第一服务环形螺母(8a)联接并且与所述一对曲柄臂中的所述至少一个曲柄臂轴向邻接 和用于阻止所述第二服务环形螺母(8b)相对于所述第一服务环形螺母(8a)的轴向位置的装置(8c)。 第一服务环形螺母(8a)包括外螺纹(8a1),并且第二服务环形螺母(8b)包括与所述外螺纹(8a1)接合的内螺纹(8b1)。

    • Described herein is a bike including a frame member linking the front and rear wheel(s) made up of a first forward section or sections extending from the front wheel(s) and a second rear section or sections extending from the rear wheel(s). The section endings mate about a lockable connection assembly that is also in communication with a seat-post connected to the seat. The frame sections pivot about a connection assembly axis in a direction perpendicular to the bike frame and the seat-post is able to be moved independent of the frame sections. A key advantage of the above bike is the high range of height adjustability allowing the bike to be used by range of different sized users. Height adjustment is also very easy and may be done toolessly. Further, maintaining the seat in a desired riding alignment independent of frame movement is important otherwise the rider position will change relative to the handlebars leading in extreme cases to falls from the bike. Use of gas assisted injection moulding in bike manufacture is also described.
    • 本文描述了一种自行车,其包括框架构件,该框架构件连接由第一前部或多个从前轮延伸的部分和从后轮延伸的第二后部或多个部分组成的前轮和后轮, 。 部分末端与可锁定连接组件相关联,所述可锁定连接组件还与连接到座椅的座椅柱连通。 框架部分在垂直于自行车框架的方向上围绕连接组件轴线枢转,并且座柱能够独立于框架部分移动。 上述自行车的一个关键优势是高度可调节性的范围,使得自行车可以被不同规模的用户使用。 高度调整也很容易,可能会做得太过分。 此外,将座椅保持在与框架移动无关的期望的骑行对准中是重要的,否则骑乘者位置将相对于在极端情况下导致自行车掉下的车把变化。 还描述了在自行车制造中使用气体辅助注射成型。
