摘要:
A fishing gear maintenance cost estimation system uses a fishing gear maintenance cost estimation program to estimate cost of maintenance of fishing gear. The fishing gear maintenance cost estimation system has an information acceptance component, a replacement part determination component, a cost computation component and a display. The information acceptance component accepts estimation basis information including product information and condition information. The product information is information for identifying a product name of fishing gear. The condition information is information for identifying condition of the fishing gear. The replacement part determination component determines a part which must be replaced on the basis of the estimation basis information. The cost computation component computes the overhaul cost including the cost of the part. The display displays the overhaul cost.

A bicycle antitheft device includes an antitheft mechanism switchable between an antitheft state and a release state, wherein the antitheft mechanism includes a first member that moves relative to a second member to move the bicycle forward and backward. A movement controlling mechanism hinders the first member from moving relative to the second member when the antitheft mechanism is in the antitheft state, and a selection mechanism is provided for selecting one of the antitheft state and the release state. Alternatively, the antitheft mechanism may include a sound generator for generating a sound when the first member moves relative to the second member and the antitheft mechanism is in the antitheft state. The movement controlling mechanism and the sound generator may be combined into a single antitheft mechanism. The movement controlling mechanism and/or sound generator may be installed inside of an internal transmission such as a hub or crank transmission, or they could be installed inside a handlebar control for the transmission.

A quick release apparatus for a bicycle for pulling and fixing a drawbar having a cam follower formed at one end thereof. The apparatus includes a housing for contacting a bicycle frame, and a rotary cam supported in the housing to be rotatable about an axis substantially perpendicular to the drawbar. The rotary cam is rotatable by a cam lever to contact the cam follower to pull the drawbar toward the housing. The rotary cam and cam lever are interconnected through a coupling device disposed at one side of the housing. The coupling device includes a first coupling for restraining a relative rotation between the rotary cam and the cam lever, and a second coupling for restraining a relative movement in a direction of the axis between the rotary cam and the cam lever.

A rotatable handgrip for a twist-grip shift control device includes a rotatable member and a flexible grip disposed over the rotatable member. One or more spaces are defined between an inner peripheral surface of the grip and an outer peripheral surface of the rotatable member so that the grip bends radially inwardly in response to pressure from a hand part (palm, finger, thumb, etc.) so as to generally conform to the hand part. The space may be formed by a recess formed on the inner peripheral surface of the grip, on the outer peripheral surface of the rotatable member, a combination of recesses on the grip and the rotatable member, or through some other structure.

A bicycle shift control device for controlling a gear shifter via a gear shift cable includes a winding member supported for rotation around an axis for winding the gear shift cable, a first control member for rotating the winding member in a first direction, and a second control member mounted concentrically with the axis. The winding member rotates in a second direction opposite the first direction in response to movement of the second control member in the direction of the axis.

A hub mechanism attachable to a bicycle frame includes a hub spindle having contact portions for contacting the frame to be fixed to the frame. The hub spindle includes small diameter portions disposed in axially opposite end regions thereof, respectively, and a large diameter portion disposed between the small diameter portions and having a substantially larger diameter than the small diameter portions. The hub mechanism further includes a hub rotatably supported by the hub spindle, and a bearing mechanism disposed between the hub spindle and the hub for allowing rotation of the hub relative to the hub spindle. The bearing mechanism includes a pair of ball bearings disposed on the small diameter portions of the hub spindle, respectively, and receivers disposed between the ball bearings and the hub spindle for receiving the ball bearings, respectively. Each of the receivers includes an extension extending to the large diameter portion of the hub spindle and engaging a periphery of the large diameter portion.
