DETAILED DESCRIPTION

(12) The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

(13) Referring to FIGS. 4-8, an antistatic shoe with a conductive member in accordance with the preferred embodiment of the invention comprises: a sole 40, the conductive member 50 and an insole 60.

(14) The sole 40 is made of an electrically conductive material, and includes a top surface 41 and a bottom surface 42. The bottom surface 42 is provided for stamping on the ground. The sole 40 has a front end 43 and a rear end 44.

(15) The conductive member 50 is disposed on the top surface 41, and includes: a body 51, and a first conductive portion 52, a resistor 53, and a second conductive portion 54 disposed on the body 51. The body 51 has a first surface 511, and an opposite second surface 512 attached to the top surface 41. The first conductive portion 52 is disposed on the first surface 511, the resistor 53 is disposed on the first surface 511 and connected to the first conductive portion 52, so that the resistor 53 is electrically connected to the first conductive portion 52. The second conductive portion 54 is connected to the first surface 511 and the second surface 512. The second conductive portion 54 penetrates or surrounds the body 51, so that the second conductive portion 54 is exposed on the first surface 511 and the second surface 512. The second conductive portion 54 on the first surface 511 is electrically connected to the resistor 53 and the sole 40.

(16) Preferably, the conductive member 50 is disposed at the front end 43 or the rear end 44.

(17) The insole 60 is mounted on the sole 40, the conductive member 50 is sandwiched between the insole 60 and the sole 40, and the first surface 511 of the conductive member 50 is attached to the insole 60. The insole 60 has a conductive portion 61 made of an electrically conductive material and provided for contacting the human body, and the conductive portion 61 is electrically connected to the first conductive portion 52. The conductive portion 61 is disposed in an offset manner to the second conductive portion 54.

(18) What mentioned above are the structural configurations of the present invention and their connection relations, and the use of the present invention is described as follows:

(19) Referring to FIGS. 4-8, when the user steps on the insole 60 and comes into contact with the conductive portion 61, and charges accumulated in the user's body are conducted to the first conductive portion 52 through the conductive portion 61. Charges are conducted to the sole 40 through the resistor 53 and the second conductive portion 54, so that the charges accumulated in the user's body are finally transmitted to the ground.

(20) Since the conductive portion 61 is arranged in an offset manner with respect to the second conductive portion 54 and the resistor 53, which allows the charges in the user's body to pass through the first conductive portion 52, the resistor 53, and the second conductive portion 54 sequentially. Therefore, the present invention not only has a simple structure to reduce manufacturing cost, but also enables the charges accumulated in the user's body to be stably conducted through the regulation of the resistor 53, thereby preventing the damage to electronic components or occurrence of sparks or discomfort caused by instantaneous and massive release of the charges accumulated in the user's body.

(21) Referring to FIGS. 9-11, in another preferred embodiment of the present invention, an insulating member 70 is further provided between the insole 60 and the conductive member 50, and is made of a non-conductive material. The insulating member 70 covers the second conductive portion 54 and the resistor 53, so that the second conductive portion 54 and the resistor 53 do not come into contact with the conductive portion 61.

(22) The insulating member 70 can block the second conductive portion 54 and the resistor 53 from contacting the conductive portion 61, thereby preventing electric connection of the second conductive portion 54 and the resistor 53 with the conductive portion 61, so as to ensure that the accumulated electric charges in the user's body can be transmitted sequentially through the conductive portion 61, the first conductive portion 52, the resistor 53, the second conductive portion 54 and the sole 40. When the charges are finally transmitted to the ground through the resistor 53, since the resistor 53 allows only a relatively small amount of charges to pass through, during the charge release process, the regulation of the resistor 53 allows the charges to be transmitted smoothly, thereby preventing the damage to electronic components or occurrence of sparks or discomfort caused by instantaneous and massive release of the charges accumulated in the user's body.

(23) More preferably, the insulating member 70 covers the second conductive portion 54 and the resistor 53 to prevent electric connection of the second conductive portion 54 and the resistor 53 to the conductive portion 61. During manufacturing, the second conductive portion 54 and the resistor 53 do not need to be specifically disposed in an offset or staggered manner with respect to the conductive portion 61 since the insulating member 70 can disconnect the second conductive portion 54 and the resistor 53 from the conductive portion 61, so as to ensure that the accumulated electric charges in the user's body can be transmitted sequentially through the conductive portion 61, the first conductive portion 52, the resistor 53, the second conductive portion 54 and the sole 40.

(24) More preferably, in the foregoing two embodiments, the resistor 53 is a surface mount device and has a resistance of 1 M to 10 M, thereby reducing the current through the resistor 53 and preventing the damage to electronic components or occurrence of sparks or discomfort caused by instantaneous and massive release of the charges accumulated in the user's body.

(25) The conductive member 50 of the present invention has a simple structure since it is only provided with the body 51, the first conductive portion 52, the resistor 53, and the second conductive portion 54. Besides, the offset arrangement of the resistor 53 and the second conductive portion 54 with respect to the conductive portion 61 allows the electric charges to be transmitted sequentially through the conductive portion 61, the first conductive portion 52, the resistor 53, the second conductive portion 54 and the sole 40, thereby preventing static electricity, and further preventing the damage to electronic components or occurrence of sparks or discomfort caused by instantaneous and massive release of the charges accumulated in the user's body.

(26) In another embodiment, the insulating member 70 prevents electric connection of the second conductive portion 54 and the resistor 53 to the conductive portion 61, so as to ensure that the accumulated electric charges in the user's body can be transmitted sequentially through the conductive portion 61, the first conductive portion 52, the resistor 53, the second conductive portion 54 and the sole 40.

(27) While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
