    DETAILED DESCRIPTION OF THE INVENTION
    As shown in FIG. 1 to FIG. 3, a covering device 100 of an opening of a building of the preferred embodiment of the present invention includes two rails 10, a shading member 20, and two coupling modules 30. The rails 10 are parallel and mounted on a frame 200. The shading member 20, which is a shading blanket in the present invention, is set between the rails 10. The coupling modules 30 are connected to a top and a bottom of the shading member 20, and each coupling module 30 has opposite ends engaging the rails 10. The structures for engagement of each of the coupling module 30 and the rail 10 are the same, so we only describe one set of them in the following.
    The rail 10 has a rack thereon on a first side 10a and a second side 10b which is opposite to the first side 10a.
    As shown in FIG. 4 to FIG. 8, the coupling module 30 has a main member 32, two coupling members 34, and two adjusting units 36. The main member 32 has an elongated tubular member 321 and two lids 322 engaging the tubular member 321 at opposite ends thereof. The tubular member 321 has an L-shaped slot 321a. Each lid 322 has two first bores 322a and a second bore 322b. The main member 32 is between the rails 10 and connected to the shading member 20.
    A shaft 38 is received in the tubular member 321, and two ends of the shaft 38 pass through the second bores 322b of the lids 322. The coupling members 34 are two gears connected to the opposite ends of the shaft 38, which means the coupling members 34 are left out of the main member 32 and are free to rotate. The coupling member 34 has teeth to engage the rack on the first side 10a of the rail 10. The teeth of the gear form a front stop face 34a of the coupling members 34. The shaft 30 makes the coupling members 34 simultaneously rotate that the coupling module 30 may move up and down smoothly.
    The adjusting units 36 are provided on opposite ends of the main member 32, each of which has a stop member 361, a guiding shaft 362, a spring 363, a connecting member 364, and a switching plate 365. The stop member 361 has two protrusions 361a at an end thereof. The protrusions 361a respectively are inserted into the first bores 322a of the lid 322. Each protrusion 361a has a rear stop face 361b. The stop member 361 further has a recess 361c (FIG. 6).
    The guiding shaft 362 has an end fixed to the tubular member 321, and the other end inserted into the recess 361c. The spring 363 is received in the recess 361c of the stop member 361, and is between the guiding shaft 362 and the bottom of the recess 361c, so that the stop member 361 is urged by the spring 363 to make the protrusion 361a normally extends out of the lid 322 via the first bores 322a.
    The connecting member 364 is connected to the stop member 361 and the switching plate 365. In an embodiment, the connecting member 364 is a U-shaped member. The stop member 361 is fit to a turned portion of the connecting member 364, therefore the connecting member 364 is able to rotate relative to the stop member 361. The stop member 361 has a flange 361d around the recess 361c against an edge 364a of the connecting member 364. The switching plate 365 is set outside the tubular member 321, and the connecting member 364 is connected to the switching plate 365 through the slot 321a. Therefore, a user may move the switching plate 365 in the L-shaped slot 321a to move the stop member 361.
    As shown in FIG. 4 and FIG. 5, in a normal condition, the stop member 361 is urged by the spring 363 to move to a first position PI, in which the protrusions 361a extend out of the lid 322 via the first bores 322a. At the first position, the rear stop face 361b of the protrusion 361a faces the front stop face 34a of the coupling member 34 to form a holding space therebetween. While the stop member 361 is moved to the first position PI, the rail 10 is in the holding space to make the teeth of the coupling member 34 unable to disengage the rack of the rail 10, and allow the coupling module 30 to move on the rail 10.
    As shown in FIG. 7 and FIG. 8, while the user moves the switching plate 365 to the left, and then moves upwards to the opposite end of the L-shaped slot 321a, the protrusions 361a now are moved to a second position P2, and are held right there. In this position, the protrusions 361a are off the rail 10, and the teeth of the coupling member 34 is able to disengage the rack of the rail 10. As a result, the shading member 20 may be taken off from the rails 10 if all the stop members 361 are moved to the second positions P2 .
    In conclusion, the user only has to move the switching plate 365 to assemble or disassemble the shading member 20. No tool is needed.
    In an embodiment, there is only one adjusting unit 36 in the coupling module 30. In other words, one end of the main member 32 has a movable protrusion like above, and the other end of the main member 32 has a fixed protrusion. User may assemble or disassemble the shading member 20 by moving the switching plate 365. Besides, the lids 322 are not a necessary element in the present invention. The coupling module 30 may still work without the lid. In an embodiment, the shading member 20 is provided with one coupling module 30 at one end, and the other end of the shading member 20 is fixed. The shading member 2 0 may be extended and folded by moving the coupling module 30.
    To summarize, the present invention relates to a covering device of an opening of a building, including two parallel rails, a shading member, a main member, and two adjusting units. Each rail has a first side and a second side. The main member is between the rails and is connected to an end of the shading member. The main member has two coupling members to engage the rails at the first sides thereof. The adjusting unit has a stop member to be moved between a first position and a second position. The stop member touches the second side of the rail while the stop member is moved to the first position, and is off the second side of the rail while the stop member is moved to the second position.
    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.
