DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1, an illuminating device 3 in accordance with the present invention is attached to a sunshade 1 that generally comprises a post 11, a rib-mounting member 12 on top of the post 11, a plurality of ribs 15 each having an end pivotally connected to the rib-mounting member 12, a runner 13 slidably mounted to the post 11, a plurality of stretchers 16 each having a first end pivotally connected to the runner 13 and a second end pivotally connected to an intermediate portion of an associated one of the ribs 15. A reel 14 is provided to the post 11 for unfolding and folding the sunshade 1. A stop 19 is mounted on the post 11 and located above the runner 13 for preventing further upward movement of the runner 13 after the sunshade 1 is unfolded. A base 17 is mounted to a lower end of the post 11 for providing a stable support.
Still referring to FIG. 1 and further to FIGS. 2 through 4, the illuminating device 3 in accordance with the present invention includes at least one light unit 31 (eight in this embodiment) mounted in the runner 13. In the illustrated embodiment, the runner 13 comprises a runner body 131 and a cover 18 mounted on top of the runner body 131. The runner body 131 includes a through-hole 132 through which the post 11 extends. The runner body 131 further includes at least one compartment 133 (eight in this embodiment) for accommodating an associated light unit 31. The cover 18 includes a through-hole 181 through which the post 11 extends. The cover 18 further includes a plurality of notches 182 for accommodating and allowing pivotal movements of lower ends of the stretchers 16. The cover 18 may be fixed on the runner body 131 by extending fasteners (such as screws, not labeled) through screw holes 134 in the runner body 131 into the cover 18.
Still referring to FIGS. 2 and 3, each light unit 31 includes a light module 311 and a connector 312. Two common wires 32 are provided for electric connection with a power source. Each connector 312 is electrically connected to the common wires 32 by wires 313. Each common wire 32 includes an end electrically connected to each connector 312, and another connector 321 is mounted on the other end of each common wire 32, which will be described later. Each light module 311 includes at least one lighting element 314 (three light-emitting diodes in this embodiment, see FIG. 3). Alternatively, each light module 311 is a single lighting element of any type. Each light module 311 is removably mounted in an associated compartment 133 by any conventional method to allow replacement when desired.
Referring to FIGS. 1, 2, and 4, in the illustrated embodiment, the power source may be a solar energy device 2 comprising a solar energy receiver 21. The solar energy receiver 21 includes a base 23 mounted on top of the rib-mounting member 12 and a transparent cover 22 mounted on the base 23. The rib-mounting member 12 includes a body 121 with a plurality of notches 123 for accommodating and allowing pivotal movements of rib ends of the ribs 15. A coupling seat 122 is provided on top of the base 23 and includes a through-hole 124 in communication with the longitudinal hole 111 of the post 11. Further, positioning slots 125 are defined in a perimeter wall of the coupling seat 122. In the illustrated embodiment, a cover 127 is mounted on top of the body 121 and the coupling seat 122 is formed on top of the cover 127.
The base 23 of the solar energy receiver 21 includes a groove 231 in an underside thereof for receiving the coupling seat 122, with positioning members (not shown) formed on a perimeter wall delimiting the groove 231 being engaged with the positioning slots 125, thereby fixing the solar energy receiver 21 on the coupling seat 122. At least one photoelectric plate 221 and at least one solar cell 233 (three in this embodiment) are mounted between the base 23 and the cover 22. Solar energy is received by the photoelectric plate 221 and transformed into electricity that is stored in the solar cells 233.
As illustrated in FIGS. 2 and 4, two wires 25 are provided and each includes a conductive pin 251 on an upper end thereof and a conductive pin 191 on a lower end 252 thereof. The conductive pins 251 are electrically connected to the solar cells 233. The wires 25 extend through the hole 124 of the coupling seat 122 into the longitudinal hole 111 of the post 11, with the lower ends 252 of the wires 25 extending into the stop 19 and with the conductive pins 191 being located outside the stop 19.
Still referring to FIGS. 2 and 4, two conductive pins 322 are provided and each extends through the cover 18, with an upper end of each conductive pin 322 being located outside the cover 18 and with a lower end of each conductive pin 322 being electrically coupled to an associated connector 321. All of the lighting modules 311 are turned on when the conductive pins 322 come into contact with the conductive pins 191.
When the runner 13 is moved upward for unfolding the sunshade 1, the runner 13 is stopped by the stop 19, with the conductive pins 322 being in contact with the conductive pins 191, as shown in FIGS. 5 and 6. Electricity from the solar cell 233 is supplied to the illuminating device 3 via the wires 25 and 32. and the light elements 314 are lit to provide illumination. When the runner 13 is moved downward, the light elements 314 are turned off, as the conductive pins 322 are disengaged from the conductive pins 191, as shown in FIGS. 3 and 4. Thus, the light modules 311 are automatically turned off when the sunshade 1 is not in use.
The illuminating device 3 is mounted in the runner 13 and thus not exposed. In other words, damage to the lighting elements 314 and the wires 32. 313, and 25 are less likely to occur. Further, the illuminating device 3 has a simple structure and thus allows easy assembling. Further, in a case that the sunshade 1 is mounted adjacent to a table 4 (FIG. 1), the illuminating effect provided by the illuminating device 3 on the runner 13 for the table 4 is better than that mounted on the ribs 15.
Referring to FIGS. 6 and 7, the runner body 131 of the runner 13 may further include a battery-mounting portion 135 for accommodating a battery unit 33 having at least one cell 331 electrically connected to one of the light module 311 for supplying electricity when the solar energy device 2 could not provide sufficient electricity or malfunctions.
FIG. 8 illustrates an alternative arrangement of the illuminating device 3. In this arrangement, the illuminating device 3 is mounted in the rib-mounting member 12 instead of the runner 13. Similar to the arrangement shown in FIGS. 1 through 7, the rib-mounting member 12 includes a plurality of compartments (not shown) for receiving the light modules 31 of the illuminating device 3. Each light unit 31 includes a light module 311 that is electrically connected to the wires 25. Two conductive pins 322 are mounted on the cover 18 of the runner 13 electrically connected with each other via a wire 320. Each wire 25 has a conductive pin 251 on an upper end thereof for electrical connection with the solar energy receiver 21 and a conductive pin 191 on a lower end thereof. Detailed description of the structure of the illuminating device 3 is not given to avoid redundancy. Similar to the arrangement shown in FIGS. 1 through 7, the lighting elements 314 are turned on when the conductive pins 322 come into contact with the conductive pins 191 and the lighting elements 314 are turned off when the conductive pins 322 are disengaged from the conductive pins 191. Further, similar to the arrangement shown in FIGS. 1 through 7, a battery unit 33 may be mounted to the mounting portion 135 of the runner 13 and include at least one cell 331 for supplying electricity when the solar energy device 2 could not provide sufficient electricity or malfunctions.
Although the invention has been explained in relation to specific embodiments, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention as hereinafter claimed.
