摘要： The forks of a bicycle receive an axle having threaded ends. A tube surrounds the axle and carries ball bearings on which a wheel housing is rotatable with a space between the tube and the housing. Specially shaped seals engage the wheel housing and the tube between the ball bearings to keep lubricant out of the space between the seals. A special lever lock on one end of the axle cooperates with a nut on the other end of the axle to draw together the parts engaged with the axle, the tube and the housing.

摘要： A caliper brake for wide-tire mountain bicycles. Each caliper arm is pivotally mounted to a stationary pivot post of the bicycle frame via a cylindrical bushing to which the arm is press fitted. A return spring is retained around the pivot post in a normally stationary portion enabling purposeful adjustment. A brake shoe holder is mounted on one end of the caliper arm, and a roller-mounting post is secured to the other end. A cam roller is mounted rotatably on the roller mounting post by a low-friction bearing and has a circumferential groove engaging a cammed edge of a cam plate, to which a brake-actuating cable is secured. The brake shoe holder is preferably asymmetrical and is mounted for adjustment lengthwise of the caliper arm and for rotation around it and is also made adjustable as to the spacing from the caliper arm and as to the rotational position around an axis perpendicular to that arm.
摘要翻译： 用于宽轮山地自行车的卡钳制动器。 每个卡钳臂通过圆柱形衬套枢转地安装到自行车车架的固定枢轴柱上，臂被压配到该套筒上。 复位弹簧被保持在枢轴柱周围的正常静止部分中，从而能够进行有目的的调整。 制动蹄架安装在卡钳臂的一端，并且一个滚轮安装柱固定到另一端。 凸轮滚子通过低摩擦轴承可旋转地安装在滚子安装柱上，并且具有接合凸轮板的凸轮边缘的周向槽，制动器致动缆线固定到该凸轮板上。 制动蹄架优选地是不对称的并且被安装用于沿卡钳臂的纵向调节并且围绕其旋转，并且还可以调整到与卡钳臂的间隔以及围绕垂直于该臂的轴线的旋转位置。

摘要： A bicycle seat post for supporting a saddle on a bicycle frame. A tube cap is secured to the upper end of a tube and provides a cylindrical-segment upper surface. There is a generally cylindrical concentric inner surface, and an oversize upward passage through both surfaces. A cylindrical swivel pin is in engagement with the inner surface. The saddle has a rigid frame that is to be clamped between upper and lower clamp members. The lower clamp member has an upper clamping surface and a lower cylindrical-segment surface in engagement with the cylindrical upper surface of the tube cap. The upper clamp member has a lower clamping surface and a threaded vertical opening. The assembly is held together by a single bolt, preferably extending up from the bottom of the tube cap, through a diametric opening in the swivel pin, through an opening through the lower clamp member, and into the threaded opening of the upper clamp member, tightening all the members together and to the saddle. Simple rotational adjustment of the saddle is thereby afforded while retaining the saddle in its proper fore-and-aft alignment. Superior strength and ease of adjustment is also obtained.
摘要翻译： 一种用于在自行车车架上支撑鞍座的自行车座椅支柱。 管帽固定在管的上端，并提供圆柱形的上表面。 有一个大致圆柱形的同心内表面和一个向上通过两个表面的向上通道。 圆柱形旋转销与内表面接合。 鞍座具有被夹紧在上下夹具之间的刚性框架。 下夹紧构件具有与管帽的圆柱形上表面接合的上夹紧表面和下圆柱形段表面。 上夹紧构件具有下夹紧表面和螺纹垂直开口。 组件通过单个螺栓保持在一起，优选地从管帽的底部向上延伸通过旋转销中的直径开口，穿过下部夹紧构件的开口，并进入上部夹紧构件的螺纹开口， 将所有成员紧固在一起并连接到鞍座上。 由此可以提供鞍座的简单的旋转调节，同时将鞍座保持在其适当的前后对齐中。 也获得了优异的强度和便于调整。
