摘要： A bicycle crank arm has an internal flange with a plurality of mounting holes for receiving mounting fasteners. The internal flange allows the crank arm to be wider, which lends it to being cast out of a light alloy, such as magnesium or aluminum, producing a stronger and more rigid crank arm of reduced weight. Also, the mounting fasteners and the internal flange are hidden from sight, enhancing the appearance of the crank arm.
摘要翻译：自行车曲柄臂具有内部凸缘，其具有用于接收安装紧固件的多个安装孔。内部法兰允许曲柄臂更宽，从而使其摆放在诸如镁或铝之类的轻质合金中，从而产生更坚固和更刚性的减轻重量的曲柄臂。此外，安装紧固件和内部凸缘被隐藏，增加了曲柄臂的外观。

摘要： A chain engagement slot for bicycle sprockets, which enables a bicycle chain to be shifted from a smaller sprocket to a larger sprocket mounted next to it on a common cluster body. The chain partly enters the chain engagement slot, causing sufficient contact between the chain and the next sprocket tooth to enable the chain to be seated on the larger sprocket.

摘要： A two-piece crankshaft for a bicycle having a chain drive. One crank arm is welded to one end of a tubular, cylindrical spindle having a spline at its other end. The other crank arm is welded to an internally-splined boss which engages the splined end of the spindle. A pinch bolt secures the splined arm. A sprocket mounting pad having a threaded central mounting hole is welded intermediate the ends of one of the crank arms. A conventional bicycle sprocket having a central hole and a radially located driving slot slips onto the crankshaft spindle, abutts the mounting pad, and is secured to it by a bolt. The spindle is mounted in ball bearings inserted in bearing bores of the bicycle frame, and spacers are disposed between the crank arms and the bearings to position the two arms away from the frame.

摘要： An outboard ball bearing support for a bicycle pedal having a pedal spindle with an open, tubular outboard end. A shoulder bushing inserts into the open end of the pedal spindle. A drawbolt member having a head portion slips through the ball bearing's inner race, passes through the shoulder bushing, and engages internal threads in the pedal spindle near its inboard end. The drawbolt secures the bearing inner race and the shoulder bushing to the open end of the pedal spindle.

摘要： A bicycle workstand is mounted to a support structure, such as a wall or post. The workstand includes a handlebar support, which has two spaced-apart, concave-upward nests for supporting the bicycle's handlebars, and a saddle engagement means, mounted above, which positions the bicycle saddle in close proximity to the support structure. Thus, the bicycle is mounted vertically with its wheels extending out from the support structure, with the front wheel above the floor, free to turn, and with the center of the rear wheel at about eye level. The bicycle workstand can also serve as an economical storage rack.

摘要： A headset for bicycle having external forks. The headset allows the use of small standard sealed radial ball bearings, and allows for easy fork replacement by removing and replacing only two screws. Ball bearings with outer and inner races are inserted into bearing bores of the head tube of a bicycle frame. A pair of internally threaded bushings insert through the bearing inner races and are drawn together by a stud. Fasteners, such as screws, insert through mounting holes in spaced-apart mounting brackets of the external forks and engage the two bushings to secure the forks to the headset.

摘要： A bearing seal device seals the end of a ball bearing mechanism having an inner race engaging a cylindrical shaft, a plurality of balls, and an outer race. A flat elastic sealing ring abutts the inner race, which is inset, and bears against a sealing surface of the outer race. A circumferential seal engages and forms a seal on the shaft and abutts and forms a seal with the sealing ring. A bias means presses the circumferential seal against the sealing ring, which is deformed into a cup shape, and forms a seal with the sealing surface of the outer race.
