Optical projection time-piece attachment for spectacles or combination thereof

Claim 2

Optical projection time-piece attachment for spectacles or sunglasses comprising: (a) a miniature housing with mounting and securing means for attachment to a pair of spectacles or sunglasses frame such that the normal field of vision is not obstructed, (b) micro electronic circuitry means to generate electrical time of day functions, (c) electric light emitting display panel means to display time of day using said electrical time of day functions, (d) lens means to project an image of said display, said display panel and said lens disposed in said housing such that said display image is generally projected outward approximately at an angle of 45 degrees in a direction relative to a diametrical line of one viewing surface of the spectacles or sunglasses, (e) a clear reflective window means to intercept and partially reflect said projected display image back towards the eye of the spectacles or sunglasses wearer so as to produce a virtual image of said time display superimposed on the normal field of view when said display is illuminated, (f) convenient means to adjust and focus said display image, (g) means for supplying electric power to said micro electronic circuitry and said electric light emitting display, (h) readily accessible press button switch means to activate said electric light emitting display when required, (i) further miniature switch means to set said electrical time of day functions.

Claim 3

Optical projection time-piece attachment for spectacles or sunglasses as claimed in claim 1 wherein said light emitting display further comprises either numeric or linear graphical type readout to represent time of day.

Claim 4

Optical projection time-piece attachment for spectacles or sunglasses as claimed in claim 1 wherein said clear reflective window is a thin optically transparent sheet which protrudes from said housing to stand in parallel with and in front of one viewing surface of the spectacles or sunglasses when the time-piece is attached.

Claim 5

Optical projection time-piece attachment for spectacles or sunglasses as claimed in claim 1 wherein said convenient focusing adjustment further comprises a miniature thumbwheel mechanically coupled to adjust the position of said display panel relative to said lens.

Claim 6

Head up time display spectacles or sunglasses comprising: (a) micro electronic circuitry means to generate electrical time of day functions built into a spectacles or suglasses frame, (b) electric light emitting display panel means to display time of day using said electrical time of day functions mounted within a compartment built into the rim of the spectacles or sunglasses frame, (c) said compartment holding said electric light emitting display panel additionally containing a miniature lens means to project an image of said display, Said display panel and said lens disposed such that said display image is projected generally outward approximately at an angle of 45 degrees in a direction relative to a diametrical line of one viewing surface of the spectacles or sunglasses, (d) a clear reflective window means to intercept and partially reflect said projected display image back towards the eye of the spectacles or sunglasses wearer so as to produce a virtual image of said time display superimposed in the normal field of view when said display is illuminated, (e) convenient means to adjust and focus said display image, (f) means for supplying electric power to said micro electronic circuitry and said electric light emitting display, (g) readily accessible press button switch means to activate said electric light emitting display when required, (h) further miniature switch means to set said electrical time of day functions.

Claim 7

Head up time display spectacles or sunglasses comprising: (a) micro electronic circuitry means to generate electrical time of day functions built into a spectacles or suglasses frame, (b) electric light emitting display panel means to display time of day using said electrical time of day functions mounted within a compartment built into the rim of the spectacles or sunglasses frame, (c) said compartment holding said electric light emitting display panel additionally containing a miniature lens means to project an image of said display, Said display panel and said lens disposed such that said display image is projected generally outward approximately at an angle of 45 degrees in a direction relative to a diametrical line of one viewing surface of the spectacles or sunglasses, (d) a clear reflective window means to intercept and partially reflect said projected display image back towards the eye of the spectacles or sunglasses wearer so as to produce a virtual image of said time display superimposed in the normal field of view when said display is illuminated, (e) convenient means to adjust and focus said display image, (f) means for supplying electric power to said micro electronic circuitry and said electric light emitting display, (g) readily accessible press button switch means to activate said electric light emitting display when required, (h) further miniature switch means to set said electrical time of day functions.

Claim 8

Head up time display spectacles or sunglasses as claimed in claim 5 wherein said light emitting display further comprises either numeric or linear graphical type readout to represent time of day.

Claim 9

Head up time display spectacles or sunglasses as claimed in claim 5 wherein said clear reflective window is a thin optically transparent sheet mounted on to the spectacles or sunglasses frame to protrude and stand parallel with and in front of one viewing surface of the spectacles or sunglasses.

Claim 10

Head up time display spectacles or sunglasses as claimed in claim 5 wherein said convenient focussing adjustment further comprises a miniature thumbwheel mechanically coupled to adjust the position of said display panel relative to said lens.
