Abstract: A side reflector assembly is provided for mounting on a spoked wheel such as a bicycle. The assembly includes a plate-like reflector means and a cylindrical connector or coupler means to be coaxially fitted in the reflector means. The reflector means is provided at the center portion of its front face with a bottomed round aperture. The aperture is provided in the leading edge of the periphery thereof with a pair of notches for receiving a wheel spoke, and on the inner wall thereof adjacent to said notches with thicker wall portions. The reflector means is modified to have a set of three apertures on both sides thereof to accommodate different spoke arrangements.

Abstract: A multi-purpose, particularly antitheft-purpose, device for attachment and detachment of electric appliances to a bicycle, etc. is comprised of a casing and a bracket. The casing is designed to have therein one or more electric appliances, for example, a clock, or an electronic meter for determining a variety of functions including speed and distances. The casing is provided in appropriate portions with a pair of opposed grooves in which a pair of resilient contacts are slidingly inserted. The casing is also formed with a locking plate having therein an locking opening. The bracket, which is designed to be clamped onto the handle bar pipe, is composed of a main part and a subpart which are pivotally secured at one end to each other. The bracket has a pair of inserts to be slidingly inserted into the said grooves in the casing. The inserts each have on the sliding side a pair of contacts to be connected with wiring and engaged with the first mentioned contacts.

Abstract: This invention embodies a side reflector assembly adapted to be mounted on the spokes of a bicycle wheel or the like, such assembly including two slim elongated bodies bonded together. Each body has a front reflective surface comprised of at least a first planar surface and a second roof-like surface having two inclined planar sections symmetrical to the longitudinal axis of the assembly. Bolt and nut means are provided for clamping the assembly onto the wheel spokes.
