Abstract: A journal for a frame fork of a bicycle including a sleeve engaged on the frame fork and a bearing engaged in an upper portion and a lower portion respectively, the frame fork including an outer thread formed on an upper end, a member threadedly engaged on the upper end of the frame fork and pressing against one of the bearings, and a cut laterally formed in the member such that the member is separated into two portions, a bolt engaged in an aperture formed in the member and perpendicular to the cut for coupling the two portions together.

Abstract: A journal including a lower cap engaged on an end portion of a head tube of a bicycle, the lower cap having an annular recess, a bearing engaged in the annular recess of the lower cap, an upper cap threadedly engaged on the upper portion of the front fork and engaged on the bearing so that the front fork is rotatable relative to the head tube, and a compression nut threadedly engaged above the upper cap so that the upper cap can be stably retained in place.

Abstract: A bicycle hub includes a pair of sleeves rotatably supported on an axle, and a dust cap having a cylindrical portion engaged on each of the sleeves. An outer peripheral surface of one sleeve is curved, and an inner peripheral surface of a cylindrical portion of a dust cap is curved and is rotatably engaged with the curved outer peripheral surface of the sleeve so that the axle is rotatable about the dust cap by engagement between the curved outer peripheral surface of the sleeve and the curved inner peripheral surface of the cylindrical portion.

Abstract: A coupling for securing a handlebar to a bicycle frame that carries a bowl through which a standpipe is received, the bowl including a bore formed in a center for receiving the standpipe and a hole communicated with the bore, two members received in the hole and in contact with the standpipe, a bolt extended through one of the members and threadedly engaged with the other member so that the members can be clamped together by the bolt and so that the standpipe can be fixed in place by the members.

Abstract: A stop washer for a brake unit of a bicycle is generally a disc with a center hole. A stop is fixed on the disc and extends in a plane perpendicular to the disc. A brake unit of a conventional bicycle includes a pair of brake devices being respectively pivoted to two frame bars of a frame fork of the bicycle. The brake device includes a brake arm with a brake shoe. The brake arms are actuated by a cable. The stop washer is disposed on a pivot axle of the brake device such that the stop extends across a rotational plane of the brake arm for limiting the rotation of the brake arm.

Abstract: A coupling for securing a handlebar to a bicycle frame, the coupling includes a compression nut and a bowl. An inner thread is formed in an upper end of the compression nut. A sealing ring has an outer thread formed on a lower end. The sealing ring is secured in place by a threaded engagement between the sealing ring and the compression nut when the handlebar standpipe is inserted through the sealing ring into the compression nut.

Abstract: A journal for a frame fork of a bicycle includes an upper cap and a lower cap with two or more balls rotatably received between the upper cap and the lower cap. The upper cap and the lower cap are cylindrical shaped. An inner thread is formed at an upper half of the upper cap and a track surface is formed in an inner surface of a lower half of the upper cap. An annular flange is formed on an outer surface of the lower cap and an inclined and curved surface is formed at an upper and outer edge of the lower cap such that the balls are receivable between the inclined surface of the lower cap and the track surface of the upper cap. A sealing ring is seated above the flange for preventing water or dust from entering the journal.

Abstract: The present invention relates to a quick adjusting device for bicycle cables, and especially to a device having a substantially S-shaped base which cooperates with a cam, a worm and a worm gear to adjust a bicycle brake cable. Two plates formed on the bottom of the base to define an area. A wheel is slidably mounted on the cam. The worm gear and the wheel, together, clamp the brake cable. The brake cable is driven and adjusted by the worm gear and the wheel by inserting a hexagon wrench into a hexagonal slotted head of the worm and turning. A pulley is rotatably received in an area of the base for adjusting the relative position of the left side and the right side brake arms.

Abstract: A bracket bearing axle applied to a bicycle having two grooves for two snapping rings to be mounted on, and a raised ring with an arced surface to the exterior thereof. Two roller bearings are provided on the bearing axle, and a segmented tube which is flexible is provided between the two roller bearings. A pedal spindle receives the bracket bearing axle and the segmented tube with a bearing retainer threaded on one terminal side and a retaining element threaded on the other terminal side. A plurality of ball bearings are disposed between the bearing retainer and arced surface to resist the abrasion face caused by the rotation of the bearing axle. A water cap and an O-ring are provided on the bearing retainer and retarding element, respectively, to prevent water and dust from entering the bracket bearing axle device.

Abstract: An improved bicycle bottom axle cup assembly comprising a five way pipe, an axle, two cups, two ball bearings, an adjustable connector, a lock ring and a packing ring, and constructed in such way that it can be assembled without any five way pipe and adjusted to meet the need of bottom axles of different lengths.
