摘要:
A wrist watch (101) to which an engagement structure of the present invention is applied includes a recessed body (105) connected to a band (107), and a watch (103) having a projected body (141) formed on the rear side of a display portion (102), the projected body having an outer perimeter wall portion capable of fitting in an inner perimeter wall portion (117) of the recessed body (105). The inner perimeter wall portion has a wall surface formed by joining circles with their centers at a second reference axis (121) and with their diameters larger as the centers are shifted to the side of the watch portion. The outer perimeter wall portion has a wall surface formed by joining circles with their centers at a first reference axis (120) and with their diameters smaller as the centers are shifted to the side of the recessed body (105). A recessed portion provided at the outer perimeter wall portion is engaged with a projected portion provided at the inner perimeter wall portion, and the watch (103) and the recessed body (105) are disengaged by relatively rotating around the reference axis (120, 121).
摘要:
Bar-shaped temples (9a) and (9b) extending backwardly are affixed on both sides of spherical lens (1). Ear hooks (11a, 11b) made of a resilient material are fitted slidably to each of temples (9a, 9b). Ear hooks (11a, 11b) are fixed to arbitrary positions relative to temples (9a, 9b) by its resilient characteristic.

An apparatus for attachment of bicycle parts (30) in accordance with the present invention includes: a first attachment part (1) attached to component parts of a bicycle and having a flat projected piece (20); a second attachment part (3) having a fitting portion (21) slidable with respect to the projected piece and provided for attaching the first attachment part by using the fitting portion and for fixing bicycle parts thereon; and a cord (25) connected through the vicinity of the fitting portion of the second attachment part to the bicycle parts. When the projected piece and the fitting portion are engaged with each other, a portion of the cord is pressed by a tip end of the projected piece, thereby increasing a strength in cord fitting.
摘要:
A running data display unit (1) for a bicycle calculates running data such as running speed, running distance, average speed, maximum speed etc. of a bicycle, based on pulse signals from a revolution detecting portion (3). This calculation is performed by a microcomputer incorporated in the display unit. The running data obtained by the calculation are displayed in a digital form on a liquid crystal display panel (15). The liquid crystal panel (15) also makes display of a pulse mark (26). The display of the pulse mark (26) turns on and off alternately at the rise of the pulse applied normally from the revolution detecting portion (3). As a result, by the display of the pulse mark (26), the rider of the bicycle can ascertain normal operation of the display unit (1), particularly normal operation of the revolution detecting portion (3).

This calculation is performed by a microcomputer incorporated in the display unit. The running data obtained by the calculation are displayed in a digital form on a liquid crystal display panel (15). If the running data displayed on the panel (15) is the running distance, the running distance is represented as a numerical value including five figures at maximum. The running distance not attaining 1000 km (or miles) is represented down to two decimal places and when the running distance attains 1000 km (or miles), the manners of display is automatically by the microcomputer (30) changed so that display is made down to only one decimal place.
