Abstract
Abstract A safety illuminated shoe includes a plurality of illuminators secured on a printed circuit board having a flip-flap trigger switch mounted on the printed circuit board and electrically connected between two poles of a power source of batteries packed under the printed circuit board for supporting the printed circuit board, whereby upon treading of the shoe to close two contacts of the flip-flap trigger switch, the illuminators will be lit up for a predetermined time period as controlled by an integrated circuit built on the printed circuit board, and since the two contacts of the flip-flap switch are normally restored by its self resilience and can then be separated each other to prevent unexpected power consumption of the batteries.

A safety illuminated shoe comprising: a shoe (1) having a transparent holder (3) secured in a rear recess in a heel of the shoe; and an illuminating means (2) detachably embedded in an inner socket (31) of the transparent holder (3) having a plurality of illuminator clips (32) circumferentially formed on the holder (3) for holding a plurality of illuminators (26) of the illuminating means (2), said illuminating means being covered by an insole (12) inside an upper of the shoe; said illuminating means (2) including: a housing (21), a printed circuit board (22) secured in an upper portion of the housing (21), a flip-flap trigger switch (23) mounted on the printed circuit board (22), a plurality of batteries (24) secured on the printed circuit board (22), an integrated circuit (25) and a plurality of said illuminators (26) secured on the printed circuit board (22) with the integrated circuit (25) for timing control of illumination of the illuminators (26) when actuating the flip-flap trigger switch (23); the improvement which comprises: said flip-flap trigger switch (23) of the illuminating means (2) including: a base flange (230) secured on the printed circuit board (22), an upper disk portion (231) made of electrically conductive material and connected with the base flange (230) by a shallow conical wall (232) generally formed as truncated cone shape with the shallow conical wall (232) protruding and tapered upwardly from the base flange (230) to be connected with the upper disk portion (231) generally horizontally flattened, a first leading wire (233) connected between the upper disk portion (231) and a first pole of the batteries (24) which are secured under the printed circuit board (22) for supporting the printed circuit board, a lower contactor plate (234) secured on the printed circuit board (22) and positioned under the upper disk portion (231) and electrically connected to a second pole of the batteries (24) by a second leading wire (235), whereby upon depression of the upper disk portion (231) as trodden by a user's foot on the insole (12) of the shoe to close the upper disk portion (231) with the lower contactor plate (234), the illuminators (26) will be powered and lit on by the batteries (24) for safety illumination through the transparent holder (3) fixed in the heel (11) of the shoe (1).
