Take a window covering for example, the 10 common type window covering has two sliding or hinged sashes. In this type of window covering, the sashes take some space of the window. It is bad for ventilation. Another type of window covering is similar to a casement window, having two hinged sashes, one of which is pivoted on the frame, and the other one of which is slidably engaged with a rail. 15 Move the sliding sash will fold the sashes, and the folded sashes are vertical to the rail. It provides a large window opening when a user opens the sashes. However, people may run into the vertical sashes accidently when the sashes are opened. An improved window covering provides a warp rail, with which a user may move the folded sashes off the window and attach them to the wall beside the 20 window. It is easy to understand that the warp rail is expensive and is difficult to manufacture. Furthermore, the warp rail makes the sashes move in a strange way. It is not good looking. SUMMARY OF THE INVENTION 25 The primary objective of the present invention is to provide a covering of a 2 building's opening, with which people will have less chance to run into the sashes when the sashes are opened. According to the objective of the present invention, a rail module of a covering of a building's opening, including a fixed first rail, a second rail, a first 5 restricting member, and a pulley assembly. The fixed first rail has a locking slot. The second rail is turned between a first position and a second position. The second rail is connected to the first rail when the second rail is turned to the first position, and the second rail is separated from the first rail when the second rail is turned to the second position. The first restricting member is movably provided on the second rail and has a 10 contacting portion and a protrusion at opposite sides thereof. The protrusion engages the locking slot of the first rail when the second rail is turned to the first position. The pulley assembly is able to move in the first rail and the second rail when the second rail is turned to the first position. The pulley assembly has a driving portion in association with the contacting portion of the first restricting member. 15 The driving portion of the pulley assembly touches the contacting portion of the first restricting member to move the first restricting member and disengage the protrusion of the first restricting member with the locking slot of the first rail when the pulley assembly is moved to the second rail, so that the second rail is able to be turned to the second position. 20 Therefore, the hanger of the present invention provides the coverings to be moved totally off the building opening and attached to a wall besides the opening, while the rails of the present invention are straight.

However, the drawings are 25 illustrative only but not used to limit the present invention. 4 FIGS. from FIG. I to FIG. 6 show a covering of a building's opening of the embodiment of the present invention, in which the building's opening is a window, and the covering includes a frame 100, a rail module, and two sash members. Each sash member has two sashes 101, 102. These two sash members are symmetrical. So, only 5 the left sash member is described hereafter. The frame 100 is mounted in the window, and the rail module is fixed to a top section of the frame 100. The first sash (so called first movable member) 101 is pivoted on the frame 100 by a pin 105 for rotation only. The first sash 101 is hinged with the second sash 102 by a hinge 106 (FIG.7 and FIG. 9). The second sash (so 10 called second movable member) 102 is engaged with the rail module to slide and rotate. The second sash 102 has a top side 102a. The rail module includes a first rail 10 and a second rail 20. The rail module further has a fixed member 30, a pulley member 40, a base 50, a first restricting member 60, a first flexible member 70, a second restricting member 80, and a second 15 flexible member 90 for each sash member. The first rail 10 is straight, and is fixed to the frame 100. The sashes 101, 102 are under the first rail 10. The first rail 10 has a locking slot 12 adjacent to a left ends thereof The second rail 20 is next to one end of the first rail 10. The second rail 20 is 20 pivoted on the frame 100 to be turned between a first position P1 and a second position P2. An end of the second rail 20 is connected to the end of the first rail 10 to form a single straight rail when the second rail 20 is at the first position P1. The second rail 20 has a top plate 22 and two side plates 24 at opposite edges of the top plate 22. The top plate 22 has a transverse slot 221, and the transverse slot 221 is vertical to the second 25 rail 20 and has an end open at the side plate 24. 5 The fixed member 30 is a plate fixed to the frame 100, and is above the top plate 22 of the second rail 20. The fixed member 30 has a protrusion 32 in association with the first rail 10. As shown in FIG. 5 and FIG. 6, the pulley assembly 40 has a thread rod 41, a 5 carrier 42, a plurality of pulleys 43, a front wheel 44, and a rear wheel 45. The thread rod 41 is on the top side 102a of the second sash 102. The carrier 42 is a rectangular-like block, having a top side 42a and a bottom side 42b, a left side 42c, a right side, a front side 42d, and a rear side 42e. The top side 42a is opposite to the bottom side 42b, and the rest sides are between the top side 42a and the bottom side 10 42b. The right side is opposite to the left side 42c, but is not shown the drawings. The rear side 42d is opposite to the front side 42e, and they are between the right side and the left side 42c. The carrier 42 is provided with a thread hole 421 extending from the top side 42a to the bottom side 42b. The thread rod 41 is screwed into the thread hole 421 to connect the carrier 42 to the second sash 102, so the carrier 42 is able to turn 15 related to the second sash 102. The pulleys 43 are provided on the right side and the left side 42c of the carrier 42, and engage the first rail 10 so that the pulley assembly 40 is able to move in the first rail 10 and move to the second rail 20 while the second rail 20 is turned to the first position Pl. The front wheel 44 and the rear wheel 45 are provided on the top side 42a of the carrier 42, and they respectively have a portion 20 beyond front side 42d and the rear side 42e of the carrier 42. The beyond portions of the front wheel 44 and the rear wheel 45 form a driving portion 44a and a stop portion 45a. The pin 105 of the first sash 101 is pivoted on the base 50, and a portion of the base 50 is in the second rail 20 so that the base 50 moves with the second rail 20. 25 The base 50 has a rod 52 received in the second rail 20, and the rod 52 is pointed along 6 the second rail 20. The first restricting member 60 is movably received in the second rail 20. The first restricting member 60 has an elongated body with an elongated slot 62. The elongated slot 62 is open at an end of the body to form an opening end. The rod 52 of 5 the base 50 enters the elongated slot 62 of the first restricting member 60 via the opening end. The first restricting member 60 further has contacting portion 64 on a lateral side of the body and adjacent the opening end of the elongated slot 62. The contacting portion 64 is a hook-like member. On the opposite end of the body, the first restricting member 60 has a protrusion 66. 10 In an embodiment, the first flexible member 70 is a spring, having opposite ends engaging the rod 52 of the base 50 and urging an inner end of the elongated slot 62 of the first restricting member 60 to urge the first restricting member 60. While the second rail 20 is at the first position P1 the protrusion 66 passes through the second rail 20 and enters the locking slot 12 of the first rail 10 (FIG. 2). 15 The second restricting member 80 has an elongated plate 81 received in the transverse slot 221 of the second rail 20. The elongated plate 81 has a pressing portion 811 and a rod 812 at opposite ends. The elongated plate 81 further has a block 82 and a stop rod 83 at a top thereof. The stop rod 83 is closer to the frame 100 than the block 82. Both the block 82 and the stop rod 83 press the top plate 22 of the second rail 20 so 20 that the second restricting member 80 moves with the second rail 20 and is limited by the transverse slot 221. The stop rod 83 touches the protrusion 32 of the fixed member 30, and the pressing portion 811 touches the frame 100 when the second rail 20 is turned to the first position Pl. The elongated plate 81 is provided with a stop plate 84 at a bottom thereof and a stop block 85 beside the rod 812. The stop block 85 is 25 received in the second rail 20, and the stop plate 84 is closer to the frame 100 than the 7 stop block 85. In an embodiment, the second flexible member 90 is a spring, having opposite ends engaging the rod 812 of the second restricting member 80 and urging an interior side of the side plate 24 of the second rail 20. The second flexible member 90 5 urges the second restricting member 80 out of the transverse slot 221 of the second rail 20. FIG. 7 shows the sashes 101, 102 in an expanding condition to close the window. As shown in FIG. 2, in the expanding condition, the second rail 20 is at the first position P1 and is connected to the first rail 10. At this time, the first restricting 10 member 60 is urged by the first flexible member 70 to have the protrusion 66 passing through a space between the pressing portion 811 and the stop plate 84 of the second restricting member 80, and engaging the locking slot 12 of the first rail 10. As a result, the second rail 20 is secured to the first rail 10. As shown in FIG. 7, while the second sash 102 is drawn to the left, the 15 pulley assembly 40 moves in the first rail 10 and toward the second rail 20, and it will turn the sashes 101, 102. Finally, the sashes 101, 102 fold up and are vertical to the first rail 10 and the second rail 20. At this time, the pulley assembly 40 moves into the second rail 20, and the driving portion 44a of the pulley assembly 40 touches the contacting portion 64 of the first restricting member 60 and pushes the first restricting 20 member 60 and make the protrusion 66 out of the locking slot 12 of the first rail 10 (FIG. 8). The protrusion 66 leaves the space between the pressing portion 811 and the stop plate 84 as well. As shown in FIG. 9 and FIG. 10, the user then turns the folded sashes 101, 102 to the left. It will turn the second rail 20 to the second position P2 from the first 25 position P1 and separate the second rail 20 from the first rail 10 at the same time. At 8 this time, the stop rod 83 leaves the protrusion 32 of the fixed member 30, and the second restricting member 80 is moved by the second flexible member 90 to move the pressing portion 811 out of the transverse slot 221. At the same time, it will move the stop plate 84 and the stop block 85 in the same direction. As shown in FIG. 10, after 5 the second rail 20 leaves the first rail 10, the stop portion 45a of the pulley assembly 40 is stopped by the stop block 85 of the second restricting member 80, and the protrusion 66 of the first restricting member 60 is stopped by the stop plate 84 of the second restricting member 80, so that the pulley assembly 40 and the first restricting member 60 will never escape from the second rail 20 even when the sashes 101, 102 are turned 10 in a reverse way. As a result, the user may turn the sashes 101, 102 for another ninety degrees, and attach the sashes 101, 102 to a wall of the building, as shown in FIG. 9. It is obvious that the sashes 101, 102 move totally off the window that may provide the maximum window opening space when the window is opened. In addition, the sashes 15 101, 102 are attached to the wall beside the window so that people will not run into them. On the contrary, when the user wants to close the window, he/she just moves the sashes 101, 102 in a reverse way. The second rail 20 will be turned to the first position P1 and reengages the first rail 10 when the sashes 101, 102 are turned back. At this time, the stop rod 83 of the second restricting member 80 touches the protrusion 32 of 20 the fixed member 30, and the pressing portion 811 presses the frame 100. It may compress the second flexible member 90 and move the second restricting member 80 into the second rail to move the second restricting member 80 back to the position when the second rail 20 is not separated. In practice, it may move the second restricting member 80 by the touching of the top rod 83 and the protrusion 32, or the 25 pressing portion 811 and the frame 100 only. Now, the pulley assembly 40 may be 9 freely move back to the first rail 10 and the sashes 101 and 102 back to the expanding condition, as shown in FIG. 1. It is noted that both the first rail 10 and the second rail 20 are straight in the present invention to achieve the same result of a conventional warped rail, so that the 5 present invention is cheaper and easier to manufacture. In above embodiment, it discloses a window covering with two sash members, and each sash member has two hinged sashes. The present invention may be applied in a covering having one sash member with two sashes, or a sash member having more than two sashes. 10 The description above is only a few preferred embodiments of the present invention. The concept of the present invention may be incorporated in, except for window, door, any type of the covering which shades an opening of a building. The equivalence of the present invention is still in the scope of claim construction of the present invention. 15 10
