1. Field of the Invention
The present invention relates generally to a covering of a building's opening, and more particularly to a detachable hanger of a covering of a building's opening.
2. Description of the Related Art
A covering for an opening of a building, such as window or door, has various types. Take a window covering for example, the common type of the window covering has two sliding or hinged sashes. In this type of window covering, the sashes take some space of the window opening. It is bad for ventilation.
Another 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. Slide the sash will fold the sashes. In this window covering, the rail is straight, and the sash can't be moved when the folded sashes fold up. A new window covering provides a warp rail, with which the folded sashes are moved off the window and attached 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 detachable hanger for a covering of a building's opening, which provides an easy way to engage and disengage the covering with a straight rail.
According to the objective of the present invention, a hanger for a covering of an opening of a building to detachably engage the covering with a rail on a sidewall of the opening, and the hanger includes a pulley assembly, which has a base and a plurality of pulleys mounted on the base for rotation, wherein the pulleys engage the rail so that the pulley assembly moves in the rail. The pulley assembly engages the covering to allow the covering to move in the rail, and the pulley assembly disengages the covering while the covering rotates for a predetermined angle.
In an embodiment, the hanger further includes restricting assembly to be moved between a first position and a second position. The restricting assembly holds an engagement of the rod and the slot when the restricting assembly is moved to the first position, and the restricting assembly is moved to the second position to allow the rod to disengage the slot while the covering rotates for the predetermined angle.
In an embodiment, a rod and a slot serve the engagement of the pulley assembly and the covering. The slot has a lateral opening, and the rod only leaves the slot via the lateral opening to disengage the pulley assembly and the covering.
In an embodiment, the restricting assembly is provided with a driving portion, which is driven by another covering to move the restricting assembly to the second position while the covering rotates for the predetermined angle.
In an embodiment, a biasing member is provided to temporarily fix the pulley assembly to the rail while the covering rotates for the predetermined angle.
Therefore, the hanger of the present invention may be incorporated in a straight rail, and make the sashes totally move off the window opening.
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.

The top section 12a and the bottom section 12b are connected through ribs, and therefore, a space S is formed between the top section 12a and the bottom section 12b. The pulleys 14 are mounted on the top section 12a for free rotation. The pulleys 14 engage the rail 102 so that the base 12 is able to move in the rail 102.
The engaging assembly 20 includes a slot 22 and a rod 24. The slot 22 is provided on the bottom section 12b of the base 12. The slot 22 is open at a top and a bottom of the bottom section 12b and has a lateral opening 22a at a lateral side of the bottom section 12b. The rod 24 is vertical and has an end fixed to the top side 105a of the sash frame 105. In an embodiment, the rod 24 is a bolt screwed into a thread hole on the sash frame 105 and engaging the slot 22, and a head of the rod 24 is in the space S, as shown in
The restricting assembly 30 has a supporting member 32, a switch 34, and an elastic member 36.
The supporting member 32 is a rectangular frame and is fixed to the top of the bottom section 12b of the base 12 through two blots 38, and therefore the supporting member 32 is in the space S. As shown in
The switch 34 movably engages the supporting member 32. The switch 34 has two parallel arms 34a, a base 34c connected to ends of the arms 34a, a protrusion 34d on the base 34c opposite to the arms 34a, and a hook 34e connected to the base 34c at the same side with the protrusion 34d. The base 34c is received within the recess of the supporting member 32 to be moved between the front stop portion 32a and the rear stop portion 32b. The arms 34a pass through the openings 33 and has distal ends extending out of the openings 33 to form an driving portion 34b. The hook 34e passes through the passageway to have a hook portion out of the supporting member 32.
In an embodiment, the elastic member 36 is a compression spring, having a first end 36a urging the front stop portion 32a and a second end 36b engaging the protrusion 34d of the switch 34 so that the elastic member 36 will be compressed while the switch 34 is forced toward the front stop portion 32a, and the elastic member 36 will return the switch 34 while the force is gone.

The pulley assembly 40 has a base 42 and a plurality of pulleys 44 mounted on the base 42 for free rotation. The pulleys 44 engage a rail 201 on the window covering 200 so that the base 42 is able to move in the rail 201.
The engaging assembly 50 has a slot 52 and a rod 54. The slot 52 is provided on a sash frame 203 of the sash 202. In an embodiment, the sash frame 203 is provided with a recess at a corner thereof, and a lid 204 is fixed to the sash frame 203 to cover the recess. The lid 204 has a top portion 204a and a lateral portion 204b on a top edge and a lateral edge of the sash frame 203. The lid 204 further has a side portion 204c, which is vertical to both the top portion 204a and the lateral portion 204b, on a front side of the sash frame 203. The slot 52 is a curved slot extending on the top portion 204a of the lid 204. The slot 52 extends to the lateral portion 204b to form a lateral opening 52a thereon. The rod 54 has an end fixed to the base 42 and an opposite end engaging the slot 52, as shown in
The restricting assembly 60 has a switch 62 and an elastic member 64, both of which are provided in recess of the sash frame 203 of the sash 202 and is under the lid 204. The switch 62 has a stop portion 62a and a driving portion 62b on opposite sides. The driving portion 62b extends out of the sash frame 203 via the side portion 204c. The switch 62 further has a bore 62c and an inclined face 62d on the stop portion 62a. The inclined face 62d faces the opening 52a. The elastic member 64, which can be a compression spring as well, has an end urging an inner side of the sash frame 203 and an opposite end entering the bore 62c to urge the switch 62 outwardly.
Similar to the first preferred embodiment, when the sashes 202, 205 expand to close the window covering 200, the rod 54 is restricted by the stop portion 62a of the switch 62 and stays in the slot 52. We define it that the switch 62 is in a first position.
While one moves the sash 202 toward the sash 205, the hinged sashes 202, 205 rotate, and the driving portion 62b of the switch 62 will touch sash 205 while the sashes 202, 205 are parallel and vertical to the rail 201. At this time, the switch 62 will be moved to a second position, in which the elastic member 64 is compressed, and the stop portion 62a leaves the slot 52 open to free the rod 54, as shown in
Next, one moves the sashes 202, 205 to make them rotate along a pin 205a. At this time, the rod 54 will leave the slot 52 via the opening 52a to disengage the hanger 2 with the sash 202 (
On the contrary, the sashes 202, 205 may be moved back in a reverse way to make the rod 54 enter the slot 52 via the opening 52a that may reengage the sash 202 with the rail 201 again. As a result, the sashes 202, 205 may move in the rail 201 to close the window covering 200.
