There can be obtained a handlebar stem ensuring that a speed indicator provides a readily observable indication and in addition thereto capable of achieving a reduction in size and weight. A handlebar stem (10) attaching a bicycle's handlebar includes a rod (21) attaching the handlebar stem to the bicycle; a speed indicator (3) receiving a signal from a speed sensor to display speed; and an indicator housing (1) located at a front protrusion (6) extending in a forward direction to traverse the rod to house the speed indicator, the indicator housing, as seen along the rod, overlapping or being adjacent to the rod.

There is provided a bicycle head lamp employing an LED having high energy efficiency to be capable of provide sufficiently increased illuminance at a center position a predetermined distance ahead and also satisfying a predetermined distribution of light. A head lamp (10) attached to a bicycle includes a casing (31), a plurality of adjacently arranged LEDs (1-5), and a lens (11-15) arranged closer to an opening for each LED.

An attaching equipment (25) consists of a bracket (1) and a spacer (3) which is slidable in bracket (1). When a band (21b) formed of an elastic body is inserted through band inserting slit (5) of bracket (1) and band inserting slit (7) of spacer (3) and the band is let off, spacer (3) moves because of the tension of band (21b), whereby blade-like portions (29, 31) formed at end portions of band inserting slits (5, 7) pinch the band (21b), preventing falling of the band out of the band inserting slits (5, 7). When a force is applied to spacer (3) so as to align band inserting slits (5) and (7) with each other, band (21b) is allowed to freely move in band inserting slits (5, 7).

In a lamp body (25) to which a switch knob (3) is attached, an opening (19) corresponding to the switch knob (3) is formed. Opening (19) has opposing sidewalls (20a, 20b), and on each of the sidewalls, three grooves (21a, 21b) are provided. On one surface of a knob body (27) of the switch knob (3), a pair of projecting pieces (31a, 31b) are provided spaced from each other by such a distance that allows the projecting pieces to be in contact with the sidewalls (20a, 20b) of the opening (19), and at each of the projecting pieces, a beam portion (33a, 33b) is formed. On each of the beam portions (33a, 33b), a projection (35a, 35b) is provided on the outer surface, and stable engagement with the vertical groove (21a, 21b) is realized.
摘要:
A light emitting apparatus for a bicycle includes a pulse generator (IC,C₁,R₁,R₂) for generating pulses having a predetermined period and a predetermined duty cycle, a light emitter (L) for emitting light when a voltage is applied, and a voltage applying apparatus (10) for applying a voltage to the light emitting apparatus in response to the generated pulses, and the pulse generator (IC,C₁,R₁,R₂) generates pulses which allows the light emitted from the light emitter (L) to be visually recognized as light continuously emitted, by a person. Namely, the voltage is applied intermittently to the light emitter (L), such that the light emission by the light emitter (L) can be visually recognized as light continuously emitted. Therefore, by the light emitting apparatus for the bicycle, brighter light can be emitted and power consumption by the circuit as a whole can be reduced, as compared with the prior art.
