1. Field of the Invention
The present invention relates to a covering, and more particularly to a covering of a building's opening.
2. Description of the Related Art
A covering for an opening of a building, such as sashes for a window or doors for an entrance, has various types. Take a window covering for example, the 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.
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 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.
The primary objective of the present invention is to provide a covering of a 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 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 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.
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.
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.
The detailed description and technical contents of the present invention will be explained with reference to the accompanying drawings. However, the drawings are illustrative only but not used to limit the present invention.
FIGS. from
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 (
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 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 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 rail 20 and has an end open at the side plate 24.
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
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. The base 50 has a rod 52 received in the second rail 20, and the rod 52 is pointed along 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 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.
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 (
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 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 P1. 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 received in the second rail 20, and the stop plate 84 is closer to the frame 100 than the 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 urges the second restricting member 80 out of the transverse slot 221 of the second rail 20.
As shown in
As shown in
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
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 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.
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.
