    DETAILED DESCRIPTION OF THE INVENTION
    As shown in FIG. 1, a coupling device of the first preferred embodiment of the present invention is used to couple a retractable shading member 100 to a frame. The coupling device has two coupling modules 20 and a frame.
    The frame has two parallel rails 10. As shown in FIG. 2, each rail 10 has a slot 12 and an engaging member 14. In an embodiment, the engaging member 14 is a rack beside the slot 12. The slot 12 and the engaging member 14 in one rail are aligned with the slot 12 and the engaging member 14 on the other rail 10.
    The coupling modules 20 are mounted on a top and a bottom of the shading member 100. As shown in FIG. 3 and FIG. 4, each coupling module 20 has a main member 21, a shaft 22, two positioning members 23, four reinforced plates 24, two pushing members 25, and two controlling members 26.
    The main members 21 are two rectangular tubular members to be connected to the top and the bottom of the shading member 100. Each main member 21 has two guiding slots 211 on a front side and adjacent to opposite ends thereof. As shown in FIG. 4, the guiding slot 211 has a first end 211A and a second end 211B at opposite ends. The guiding slot 211 is an L-shaped slot having a horizontal section and a vertical section. The first end 211A is on a top of the vertical section, and the second end 211B is on a right of the horizontal section (FIG. 3). The main member 21 further has an opening 212 on each end thereof and a protrusion 213 beside the opening 212. A flexible member 214 engages the protrusion 213. The flexible member 214 is an arched steel wire, and of course, it could be any kind of flexible member.
    The shaft 22 is received in the main member 21 for free rotation. In an embodiment, the shaft 22 is has a hexagonal cross section, and it could be triangular, tetragonal, or any shape other than round.
    Each positioning member 23 has a recess 231 which fits the shaft 22. The positioning member 23 has a flange 232 around an end where the recess 231 is provided and a gear 233 on the other end. The gear 233 has an inclined face S on teeth thereof. The shaft 22 is inserted into the recess 231 of the positioning member 23, and the gear 233 extends out of the main member 21 via the opening 212. The positioning member 23 is able to move inwards and outwards relative to the shaft 22.
    The reinforced plates 24 are made of a rigid material, and are provided in the main member 21. Two of the reinforced plates 24 press one of the positioning members 23 on a top and a bottom thereof, and the other two reinforced plates 24 press the other positioning member 23 in the same way. The reinforced plates 24 provide the positioning members 23 with friction to increase the precision of positioning and stability of the positioning members 23.
    In this embodiment, the pushing members 25 are two springs received in the recesses 231 of the positioning members 23 respectively. The pushing members 25 are between bottoms of the recesses 231 and the shaft 22 to urge the positioning members 23 outwards.
    Each controlling member 2 6 has a ring 2 61 and an operating plate 262. The operating plate 262 is outside of the main member 21, and the ring 2 61 is connected to the operating plate 262 through the guiding slots 211. The ring 261 fits the corresponding positioning member 23 and against the flange 232. A user may move the operating plate 262 between a first position (the controlling member 26 is moved to the first end 211A of the guiding slot 211, FIG. 5) and a second position (the controlling member 26 is moved to the second end 21 IB of the guiding slot 211, FIG. 3) . When the controlling member 26 is moved to the first position, as shown in FIG. 5, the ring 2 61 moves the positioning member 23 inwards. The controlling member 2 6 will be held at the first position because of the vertical section of the guiding slot 211. While the controlling member 26 leaves the vertical section of the guiding slot 211, the pushing member 25 will move the positioning member 23 as well as the controlling member 26 outwards until the controlling member 26 arrives at the second position. In the second position, as shown in FIG. 3, the gear 233 extends out of the main member 21 through the opening 212. The pushing member 25 keeps urging the positioning member 23 to hold the controlling member 26 at the second position.
    As shown in FIG. 6, before the shading member 100 is mounted to the frame, the shading member 100 is retracted so that the user holds both the main members 21, and the controlling members 26 are moved to the first position to receive the gears 233 in the main member 21. Next, the protrusions 213 of the main members 21 engage with the corresponding slots 12 of the rails 10. The flexible members 214 now will urge bottoms of the slots 12 to stabilize the main members 21. The flexible members 214 will hold the engagements of the protrusions 213 and the slots 12 as well. At this time, the gears 233 are disengaged with the racks 14. Next, as shown in FIG. 7, the operating plates 262 are moved off the vertical sections of the guiding slots 211, and the pushing members 25 will take over to move the controlling members 26 to the second positions. At this time, the gears 233 are moved out of the main members 21 to engage the corresponding racks 14. There are four gears 233 engaging two racks 14 which make the shading member 100 firmly mounted on the rails 10 and able to move on the rails 10.
    After that, the user may move the main members 21 up or down to extend or retract the shading member 100 (FIGS. 2 and 6) . The frame may be mounted on a window or a door, or the frame is a frame of a window or a door. If the user wants to take shading member 100 off the frame, he/she only has to move the operating plates 2 62 from the second positions to the first position. The gears 233 are moved back into the main members 21, and the shading member 100 may be taken off in a reverse steps.
    The shaft 22 makes the gears 233 at the opposite ends thereof rotate simultaneously. Therefore, the main member 21 will keep horizontal when it is moving on the rails. It may provide the main member 21 a smooth movement on the coupling modules 20.
    The reinforced plates 24 increase the strength of the main member 21, and keep the positioning members 23 in position while they are rotating. They are helpful to the movement of the main member 21 as well.
    The inclined faces S of the gears 233 make the engagement of the gears 233 and the racks 14 easier and faster.
    In conclusion, the cover device of the present invention may provide the window or the door all the functions as described in the background. It further makes the shading member to be assembled and disassembled in an easy way.
    FIG. 8 shows a coupling device of the second preferred embodiment of the present invention, which is similar to the first preferred embodiment, except that guiding slots are on a top or a bottom of the main member 31. Opposite sidewalls of the guiding slot form a pair of tracks 312. The controlling member 32 has a base and a protrusion on the base. The base is wider than the protrusion and the guiding slot, and the guiding slot is slightly wider than the protrusion. The base is under the guiding slot and against the main member 31. The protrusion is in the guiding slot and guided by the tracks 312. The controlling member 32 is operable to move the positioning member 33 as described above.
    To summarize, the invention relates to a coupling device of a shading member, which device includes a frame and two coupling modules. Each coupling module includes a main member fixed to a top or a bottom of the shading member, two positioning members connected to the main member, and two controlling members connected to the positioning members. The positioning members are received in the main member, each of which has a gear to engage a rack of the frame. The positioning members are movable by moving the controlling members to make the gears engage or disengage the racks. As a result, the shading member is able to be assembled or disassembled in an easy way.
    The shading members may also be slats, a valance, or other equivalent members. The coupling member may be a rack, a chain, or other equivalent members. Each main member may only need one set of the movable positioning member and the controlling member only. It will have the same function.
    It must be pointed out that the embodiments described above are only some preferred embodiments of the present invention. All equivalent structures which employ the concepts disclosed in this specification and the appended claims should fall within the scope of the present invention.
