Abstract
Abstract Shoes having illuminated portions thereof. An e.m.f. source is preferably disposed within a cavity in a platform sole of a shoe, and a light bulb and means for operatively connecting and disconnecting the light bulb from the source of e.m.f. are preferably disposed within a cavity in a transparent heel. The means for operatively connecting and disconnecting the light bulb from the e.m.f. source may include a tilt switch, a threeposition manually actuated switch, and a recharging switch when the e.m.f. source is rechargeable.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
156 words
A shoe comprising: a. a sole, b. an upper, c. a heel, d. a source of e.m.f., e. a light bulb adapted to be operatively connected to said e.m.f. source, f. a circuit operatively connecting said source of e.m.f. and said light bulb, g. means for selectively connecting and disconnecting said e.m.f. source from said light bulb dependent upon the relative orientation of said shoe, said means including a tilt switch disposed within said circuit operatively connecting said source of e.m.f. and said light bulb, and h. means for selectively connecting and disconnecting said tilt switch from said circuit operatively connecting said source of e.m.f. and said light bulb, said means including a manually actuated switch having a first position thereof wherein said tilt switch is inserted in said circuit and a second position thereof wherein said tilt switch is not inserted in said circuit and said source of e.m.f. and said light bulb are disconnected.
Claim 2
Dependent Claim
156 words
A shoe comprising: a. a sole, b. an upper, c. a heel, d. a source of e.m.f., e. a light bulb adapted to be operatively connected to said e.m.f. source, f. a circuit operatively connecting said source of e.m.f. and said light bulb, g. means for selectively connecting and disconnecting said e.m.f. source from said light bulb dependent upon the relative orientation of said shoe, said means including a tilt switch disposed within said circuit operatively connecting said source of e.m.f. and said light bulb, and h. means for selectively connecting and disconnecting said tilt switch from said circuit operatively connecting said source of e.m.f. and said light bulb, said means including a manually actuated switch having a first position thereof wherein said tilt switch is inserted in said circuit and a second position thereof wherein said tilt switch is not inserted in said circuit and said source of e.m.f. and said light bulb are disconnected.
Claim 3
Dependent Claim
64 words
A shoe as recited in claim 1 further comprising means for allowing continuous operative connection of said e.m.f. source and said light bulb, said means comprising said manually actuated switch, said switch having a third position thereof wherein said tilt switch is not inserted in said circuit but where continuous connection between said e.m.f. source and said light bulb by said circuit is provided.
