DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to FIGS. 1 to 3. The present invention includes a slipproof pad main body 1, a tread body 2 and a light source 4. The slipproof pad main body 1 is made from an elastic transparent material. Multiple slipproof bosses 15 are arranged along a periphery of the slipproof pad main body 1. The center of the top face of the slipproof pad main body 1 is formed with a receiving space 11. A bottom side of the periphery of the receiving space 11 is formed with multiple locating mortises 111. An inner annular rib 12 is disposed at the center of the receiving space 11 to define an internal cell room 121 in which a cell 3 can be accommodated. Two opposite side passages 13 extend from the periphery of the annular rib 12 in reverse directions. The two side passages 13 respectively communicate with two lateral chambers 14. An adjoining section of each side passage 13 adjacent to the lateral chamber 14 is formed with a split 131. Two sides of a middle section of the lateral chamber 14 are respectively formed with two channels 141. Two light sources 4 (such as light-emitting diodes) are disposed in the lateral chambers 14 of the slipproof pad main body 1. Each light source 4 has an annular flange 41 inserted and located in the channel 141. A bottom of the light source 4 has a positive conductive section 42 and a negative conductive section 43 respectively extending to two sides of the positive electrode 31 and negative electrode 32 of the cell 3. The tread body 2 is also made from elastic transparent material. A protruding press section 22 is disposed at the center of one side of the tread body 2 corresponding to the cell room 121 of the slipproof pad main body 1. The tread body 2 is formed with a peripheral wall 21 around the press section 22 corresponding to the receiving space 11 of the slipproof pad main body 1. Multiple tenons 211 are formed on outer periphery of the peripheral wall 21 respectively corresponding to the locating mortises 111 of the receiving space 11. Two opposite sides of the peripheral wall 21 are respectively formed with two arced recesses 23. A lateral cover 24 outward extends from a portion of the peripheral wall 21 beside each arced recess 23. Two lateral projections 241 protrude from two sides of a middle section of each lateral cover 24.
When assembled, at least one slipproof pad main body 1 is disposed on a slide board 5 (or ski board). The tread body 2 is fitted in the receiving space 11 of the slipproof pad main body 1 to cover the receiving space 11. The tenons 211 are inlaid and located in the locating mortises 111. At this time, the lateral covers 24 cover the side chambers 14 with the lateral projections 241 inserted in the channels 141 so as to locate the light sources 4. The arced recesses 23 of the tread body 2 are inserted in the splits 131 of the slipproof pad main body 1 to restrict the positive conductive sections 42 and the negative conductive sections 43 of the light sources 4 within the arced recesses 23. The press section 22 of the tread body 2 is positioned right above the cell room 121 (the cell 3) of the slipproof pad main body 1.
FIG. 4 is a sectional assembled view of the first embodiment of the present invention. Also referring to FIGS. 5 and 6, when an external force is not applied to the tread body 2, the periphery of the tread body 2 abuts against the periphery of the opening of the receiving space 11 of the slipproof pad main body 1. Under such circumstance, the press section 22 is suspended and the positive conductive sections 42 of the light sources 4 are spaced from the positive electrode 31 of the cell 3 by a certain distance. When a user steps and stands on the tread body 2, due to the weight, the press section 22 of the tread body 2 is depressed to press down the positive conductive sections 42. At this time, the positive conductive sections 42 contact with the positive electrode 31 of the cell 3. The negative conductive sections 43 originally contact with the negative electrode 32 so that the light sources 4 are electrically connected with the cell 3 to emit light through the slipproof pad main body 1 and the tread body 2 to outer side. Accordingly, in a dim environment, a warning effect or local illuminating effect can be achieved.
FIG. 7 is a perspective exploded view of a second embodiment of the present invention. Also referring to FIG. 8, the center of the slipproof pad main body 1 is formed with a receiving space 101. A controlling circuit board 16 is disposed on the bottom side of the receiving space 101. At least two arced walls are formed on the center of the controlling circuit board 16 to define a cell room 161 in which a cell 3 can be accommodated. A negative electrode conductive plate 162 is disposed in the cell room 161 for contacting with the negative electrode 32 of the cell 3. A bottom side of the periphery of the receiving space 101 is formed with multiple locating mortises 111. In addition, two lateral chambers 14 are formed on two sides of the receiving space 101 as in the first embodiment. Multiple slipproof bosses 15 are arranged along a periphery of the slipproof pad main body 1 as in the first embodiment. Two light sources 4 are arranged in the lateral chambers 14. The positive conductive sections 42 of the light sources 4 extend to a position beside the positive electrode 31 of the cell 3. The negative conductive sections 43 are directly soldered on the contacts of the controlling circuit board 16, which contacts are electrically connected to the negative electrode conductive plate 162. The tread body 2 is identical to that of the first embodiment. The tread body 2 is fitted in the receiving space 101 as in the first embodiment.
In a natural state, that is, when an external force is not applied to the tread body 2, the press section 22 is suspended and the positive conductive sections 42 of the light sources 4 are spaced from the positive electrode 31 of the cell 3 by a certain distance. When a user steps and stands on the tread body 2, due to the weight, the press section 22 of the tread body 2 is depressed to press down the positive conductive sections 42 of the light sources 4. At this time, the positive conductive sections 42 contact with the positive electrode 31 of the cell 3. The negative conductive sections 43 are electrically connected with the circuit board 16 so as to form a controlling circuit. Accordingly, the light sources 4 will emit light through the slipproof pad main body 1 and the tread body 2 to outer side.
By means of the controlling circuit board 16, multiple light sources 4 with different colors can be turned on to emit different colors of light. Alternatively, one single light source 4 can emit different colors of light. Accordingly, different colors of light can be periodically emitted to achieve a flickering effect.
FIG. 9 shows still another embodiment of the present invention, in which the slipproof pad main body 6 and the tread body 60 are identical to the slipproof pad main body 1 and the tread body 2 of the first embodiment. The only difference between the two embodiments is that they have different appearances. The slipproof pad main body 6 has waved section 65 along the periphery for achieving slipproof effect as the slipproof bosses 15.
FIG. 10 shows still another embodiment of the present invention, in which the slipproof pad main body 7 is formed with a central receiving space in which a cell is accommodated. A tread body 70 is fitted in the receiving space. Two lateral receiving spaces 72 are defined by multiple protective petals 71 on two opposite sides of the slipproof pad main body 7. An inner transparent shade 73 is disposed in each lateral receiving space 72. A light source is accommodated in the inner shade 73. Two conductive sections of the light source extend to a position beside the cell under the tread body 70. When the tread body 70 is pressed, the light source is electrically connected with the cell to emit light through the inner shade 73. The protective petals 71 serve to provide a slipproof effect.
The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
