BRIEF SUMMARY OF THE INVENTION

An objective of the present invention is to provide an illuminating device mounted to a middle of a pair of glasses and adjustable in illuminating angle.

An illuminating device for a pair of glasses includes an illumination control device, a housing, a coupling seat, and a positioning mechanism. The illumination control device is received in the housing and includes a lamp emitting light beams out of the housing. The coupling seat includes first and second pivotal portions. The housing is pivotably coupled with the first and second pivotal portions, so that the housing is pivotable relative to the coupling seat. The coupling seat further includes a coupling section adapted to be coupled to a middle of the pair of glasses. The positioning mechanism retains the housing in a desired angular position relative to the coupling seat, adjusting an illuminating angle of the lamp.

The present invention will become clearer in light of the following detailed description of an illustrative embodiment of this invention described in connection with the drawings.

DETAILED DESCRIPTION OF THE INVENTION

An illuminating device of a first embodiment according to the preferred teachings of the present invention is shown inFIGS. 1-6of the drawings and mounted to a middle of a pair of glasses5. In the most preferred form shown, the illuminating device is mounted to the middle of a frame of the pair of glasses5. The illuminating device includes an illumination control device1, a housing2, a coupling seat3, and a positioning mechanism. The illumination control device1includes a circuit board11, two lamps12such as light-emitting diodes, and a switch13. A battery unit and control components are mounted on the circuit board11and electrically connected to the lights12. The switch13controls on/off of the lights12that emit light beams out of the housing2.

The housing2includes a cover21and a bottom board22mounted to a bottom of the cover21. The cover21includes a compartment211receiving the circuit board11. The cover21further includes two grooves212for receiving the lamps12. Furthermore, the cover21includes an opening213in a top side thereof for receiving the switch13. Further, the cover21includes a chamber214in each of two sides thereof. Further, the cover21includes a plurality of fixing holes215. The bottom board22includes two grooves221. One of the grooves211of the cover21and one of the grooves221of the bottom board22together define a groove securely holding the lamps12. The bottom board22further includes a plurality of fixing holes222. Fasteners are extended through the fixing holes215and222to fix the cover21and the bottom board22together. The bottom board22further includes two slots223extending inward from an end edge thereof and aligned with the chambers214of the cover21.

The coupling seat3includes two protrusions31on two sides thereof. Each protrusion31is extended through an open end of one of the slots223into one of the chambers214. Each protrusion31includes a pivotal portion32having a width larger than a width of the protrusion31and than a width of the slots223. Each pivotal portion32includes circular cross sections and received in one of the chambers214of the cover21, so that the coupling seat3will not disengage from the housing2. Furthermore, the housing2is pivotable relative to the coupling seat3due to provision of the pivotal portions32. The coupling seat3further includes a coupling section33having a coupling hole for coupling with the middle of the frame of the pair of glasses5by a fastener.

The positioning mechanism in the first embodiment includes two elastic elements4respectively received in the chambers214of the cover21. Each elastic element4includes a first end pressing against a wall of one of the chambers214and a second end pressing against one of the pivotal portions32. Thus, a suitable coupling tightness is provided between the coupling seat3and the cover21by the elastic elements4.

Since the illuminating device is mounted to the middle of the frame of the pair of glasses5, the lamps12illuminate a central area in front of the pair of glasses5. The elastic elements4and the pivotal portions32are hidden in the housing2, providing an aesthetically pleasing effect. The housing2can be manually pivoted relative to the coupling seat3to a desired angular position (FIG. 6) to provide desired illuminating effect. After adjustment, each elastic element4presses against the wall of one of the chambers214and one of the pivotal portions32to retain the housing2in the desired angular position. Thus, the lamps2can provide concentrated crosslight to a precise location in front of the pair of glasses5, and the illuminating angles of the lamps2can be adjusted.

FIGS. 7 and 8illustrate a second embodiment of the present invention, wherein the cover (now designated61) of the housing (now designated6) includes a pin hole612in each of two sides thereof and in communication with one of the chambers214. Furthermore, the bottom board (now designated62) includes two teeth621. Furthermore, each pivotal portion (now designated71) of the coupling seat (now designated7) includes a plurality of annularly spaced teeth72on an inner face thereof and selectively engaged with one of the teeth621to position the housing6. Each pivotal portion71further includes a pivot hole73extending from the inner face through an outer face of the pivotal portion71. A pin613is extended through each of the pivot holes612into the pivot hole713of one of the pivotal portions71, allowing the house6to pivot relative to the coupling seat7until a desired angular position is reached. The teeth72and621provide a reliable retaining effect for the housing6.

FIG. 9shows a third embodiment modified from the second embodiment, wherein each chamber (now designated81) of the housing (now designated8) includes a tooth811for selectively engaging with the teeth72of one of the pivotal portions71of the coupling seat7to retain the housing8in a desired angular position relative to the coupling seat7.

FIG. 10illustrates a fourth embodiment modified from the first embodiment, wherein the housing90does not include chambers214. Each elastic element4includes a first end pressing against an outer side of the housing90and a second end pressing against one of the pivotal portions (now designated911) of the coupling seat (now designated91). A desired positioning effect is provided for the housing90even though the elastic elements4are exposed.

The illuminating device1can include only one lamp12, and housing2can include only one compartment214in a desired location. Furthermore, the bottom board22can include only one slot223. Further, the housing2can be pivotably coupled to the coupling seat3by other arrangements.
