DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1, a first preferred embodiment of a shoe having light emitting function includes a sole 1, a light emitting device 2, and a shoe body 3.
The sole 1 is joined to a heel 11 at a rear end portion thereof. Both the sole 1 and the heel 11 are preferably transparent, and they have to be at least translucent. The heel 11 has a holding room 111 therein. And, the sole 1 has a through hole right above the holding room 111 of the heel 11. The heel 11 has a holding tunnel 112 under and communicating with the holding room 111. Furthermore, the sole 1 has a lengthways-extending holding groove 12 on the upper side thereof, which holding groove 12 communicates with the holding room 111 of the heel 11, and the sole 1 has several locating grooves 13 on the upper side thereof, which extend sideways from the holding groove 12.
The light emitting device 2 includes a battery holder 21, several batteries 22 held in the battery holder 21, cords 23, several light emitting elements 24 such as light emitting diodes, and a control circuit 25 (FIG. 2). The light emitting elements 24 are connected to the cords 23. The control circuit 25 includes a control IC, resistors, and a switch 251, and the control circuit 25 is electrically connected to the batteries 22 and the cords 23 for controlling the light emitting elements 24; the switch 251 is used for switching the control circuit 25 on, and for switching the control circuit 25 off, and it can be a vibration switch or a sliding switch.
The shoe body 3 has a through hole 31 on a rear end portion thereof, a covering part 32 for the through hole 31, and a pressing member 33 fitted in the through hole 31. The covering part 32 has an aperture 321 while the pressing member 33 has an aperture 331. The apertures 321 and 331 will face each other, and form a passage when the pressing member 33 is fitted in position, and when the covering part 32 is closed. And, an insulating plate 34 is used for cutting off the power supply to the light emitting elements 24, plus for preventing electricity leakage, which insulating plate 34 will disconnect the batteries 22 of the light emitting device 2 when passed through the apertures 321 and 331 of the covering part 32 and the pressing member 33, and passed between two adjacent ones of the batteries 32.
In assembly, the battery holder 21 is positioned in the holding room 111 of the heel 11, and the cords 23 are positioned in the holding groove 12 of the sole 1 and the holding tunnel 112 of the heel 11, and the light emitting elements 24 are respectively positioned in the locating grooves 13 of the sole 1 and the holding tunnel 112 of the heel 11. Then, the holding groove 12 and the locating grooves 13 are filled with glue so that the cords 23 and the light emitting elements 24 are fixed. And, the shoe body 3 is joined to the sole 1 with the pressing member 33 thereof being pressed against and fixing the batteries 22 held in the holding room 111 of the heel 11. Therefore, the user is allowed to change batteries after the covering part 32 of the shoe body 3 is opened, and the pressing member 33 removed.
Thus, the control circuit 25 will be switched on, and make the light emitting elements 24 emit light in a certain manner, e.g. to keep shining, and to flash repeatedly, when the wearer of the shoe is walking, running or dancing.
Because the sole 1 will become thinner gradually through use, the cords 23 and the light emitting elements 24 in the grooves 12 and 13 will be exposed to outside and left unprotected after the shoe is used for a certain length of time. Referring to FIG. 5, the sole 1 is formed with strengthening protrusions 14 on the lower side thereof, which are right under the holding groove 12 and the locating grooves 13; thus, the cords 23 and the light emitting elements 24 won't be exposed to outside even after the shoe is used for a long time.
Referring to FIGS. 6 and 7, alternatively, the light emitting device 2 is equipped with an EL plate 24 used for producing light, which is stuck on an upper side of the sole 1, and connected to the cords 23; thus, the shoe will shine when the EL plate 24 is powered.
Referring to FIG. 8, alternatively, the light emitting device 2 is equipped with an EL sheet 24 used for producing light, which is stuck on an outer side of the shoe body 3, and connected to the cords 23; thus, the shoe will shine when the EL sheet 24 is powered.
From the above description, it can be easily understood that the shoe of the present invention will shine to look more attractive while serving it major functions, and consumers have additional choices.
