1. Field of the Invention
The present invention relates to a window covering and, more particularly, to a magnetically attractive shade.
2. Description of the Related Art
A conventional roman shade comprises a headrail, a shade cloth mounted on and extended from the headrail, a plurality of transverse rods mounted on the shade cloth, and a lift cord extended through the shade cloth and secured to the bottom of the shade cloth to move the shade cloth upward and downward. When the lift cord is pulled, the transverse rods are driven and moved to roll or expand the shade cloth. Thus, the shade cloth is lifted and folded by the lift cord to allow passage of the solar rays and is lowered and expanded by the lift cord to provide a shading effect. However, when the shade cloth is fully expanded, the solar rays cannot penetrate the shade cloth so that the indoor light is too weak, and when the shade cloth is fully folded, the solar rays are directly projected into the indoor so that the indoor light is too strong. In addition, the shade cloth has a constant light permeability, so that the shade cloth provides a single shading effect without changing the indoor viewing effect and cannot satisfy the user's different requirements. Further, when the shade cloth is fully folded, the indoor condition is exposed to the ambient environment, so that the conventional roman shade cannot prevent a person from peeping outdoors, thereby decreasing the privacy of the house. Further, the lift cord depends from a side of the roman shade so that the lift cord is easily tangled with a child's neck, thereby causing danger to the child. Further, the lift cord protrudes outwardly from the roman shade and is swayed or deflected easily due to a wind blowing, thereby decreasing the aesthetic quality of the roman shade.
The primary objective of the present invention is to provide a magnetically attractive shade that can regulate the shading effect and the indoor brightness.
In accordance with the present invention, there is provided a shade comprising a main unit and a plurality of magnetic members mounted on the main unit. The main unit includes a shade cloth member and a plurality of transverse bars mounted on the shade cloth member. The shade cloth member is provided with a first tubular portion and a second tubular portion. The shade cloth member is divided into a first shading portion and a second shading portion which are defined by the first tubular portion and the second tubular portion. The second shading portion is divided into a plurality of movable shading pieces which are juxtaposed to each other. Each of the movable shading pieces is provided with a plurality of transverse mounting sleeves so that each of the movable shading pieces .presents a multi-stage state. The transverse bars are mounted in the second tubular portion and the mounting sleeves of the movable shading pieces. The magnetic members are mounted in the transverse bars and are magnetically attracted by each other.
Preferably, the first tubular portion, the second tubular portion and each of the mounting sleeves are formed by rolling the shade cloth member.
Preferably, each of the magnetic members has a profile corresponding to that of each of the transverse bars.
Preferably, each of the transverse bars has two opposite ends each provided with an end cap, and each of the magnetic members has two opposite ends each secured by the end cap.
Preferably, each of the magnetic members is a strong magnet.
Preferably, each of the magnetic members has a length the same as that of each of the transverse bars.
Preferably, the movable shading pieces are defined by a plurality of longitudinal slits each of which extends from a bottom of the second shading portion to the second tubular portion.
Preferably, each of the transverse bars has a hollow interior and has a top face provided with a recessed arcuate positioning portion.
Preferably, the first tubular portion is located at a top of the shade cloth member, and the second tubular portion is located between the first tubular portion and a central position of the shade cloth member.
Preferably, the first shading portion is located between the first tubular portion and the second tubular portion, and the second shading portion is located under the second tubular portion.
According to the primary advantage of the present invention, the second shading portion can regulate the incident sunlight passing through the shade cloth member by expanding, partially folding or fully folding each of the movable shading pieces so as to freely adjust the shading effect of the shade cloth member, thereby facilitating the user changing the indoor brightness, and thereby providing a comfortable sensation to the user.
According to another advantage of the present invention, the user only needs to move the transverse bars to connect or separate the magnetic members so as to fold or expand each of the movable shading pieces so that each of the movable shading pieces is expanded and folded easily and conveniently, thereby facilitating the user expanding or folding the shade.
According to a further advantage of the present invention, the arrangements of the movable shading pieces can be changed arbitrarily so that the user can freely regulate the shading effect of the shade cloth member according to the environmental conditions.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
