MAGNETICALLY ATTRACTIVE SHADE ASSEMBLY
The present invention relates to a window (or door) covering and, more particularly, to a magnetically attractive shade assembly.
A conventional roman shade comprises a headrail, a shading member mounted on and extended from the headrail, a plurality of transverse rods mounted on the shading member, and a lift cord extended through the shading member and secured to the bottom of the shading member to move the shading member upward and downward. When the lift cord is pulled, the transverse rods are driven and moved to roll or expand the shading member. Thus, the shading member 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, the lift cord depends from a side of the roman shade so that the lift cord is easily tangled with a child’s neck during playing, thereby causing danger to the child. In addition, when the shading member is fully expanded, the solar rays cannot penetrate the shading member so that the indoor light is too weak, and when the shading member is fully folded, the solar rays directly irradiate the indoor room so that the indoor light is too strong.
The primary objective of the present invention is to provide a magnetically attractive shade assembly that has a lower cost of production, is operated easily and conveniently, and is used safely.
In accordance with the present invention, there is provided a magnetically attractive shade assembly comprising a shading unit, a connecting unit, a weight pole, a plurality of magnetic units and a metallic unit.
The shading unit includes a shade cloth member and a plurality of transverse mounting sleeves mounted on the shade cloth member. The shade cloth member of the shading unit has a top end provided with a first tubular portion and a bottom end provided with a second tubular portion. Each of the first tubular portion and the second tubular portion of the shade cloth member is formed by encircling and sewing the shade cloth member and has two open ends. Each of the mounting sleeves has a closed first side and an open second side. The connecting unit includes a bonding strap secured on the first tubular portion of the shade cloth member. The weight pole is mounted in the second tubular portion of the shade cloth member. The magnetic units are mounted in the mounting sleeves of the shading unit. The metallic unit is an elongate metallic bar mounted in one of the mounting sleeves of the shading unit. The metallic unit is magnetically attracted by the magnetic units so as to fold the shading unit.

Each of the first tubular portion 11 and the second tubular portion of the shade cloth member 10 is formed by encircling and sewing the shade cloth member 10 and has two open ends.
The mounting sleeves 13 are arranged in an upright manner. Each of the mounting sleeves 13 is selected from cloth material and is sewn on the shade cloth member 10. Each of the mounting sleeves 13 has a closed first side and an open second side.
The connecting unit 2 includes a bonding strap 21 secured on the first tubular portion 11 of the shade cloth member 10 by sewing. Preferably, the bonding strap 21 is a Velcro closure.
The weight pole 3 is mounted in the second tubular portion 12 of the shade cloth member 10 and has a length smaller than or equal to a width of the second tubular portion 12 of the shade cloth member 10. The weight pole 3 is inserted through the two open ends of the second tubular portion 12 into the second tubular portion 12 of the shade cloth member 10. Preferably, the weight pole 3 is selected from plastic, metallic or wood material.
The magnetic units 4 are mounted in the mounting sleeves 13 of the shading unit 1.
The metallic unit 5 is an elongate metallic bar mounted in one of the mounting sleeves 13 of the shading unit 1. The metallic unit 5 is magnetically attracted by the magnetic units 4 so as to fold the shading unit 1.
In the preferred embodiment of the present invention, the metallic unit 5 is located above the second tubular portion 12 of the shade cloth member
10, and the magnetic units 4 are located above the metallic unit 5.
In the preferred embodiment of the present invention, each of the magnetic units 4 includes an elongate pole 41 mounted in one of the mounting sleeves 13 of the shading unit 1, and at least one magnet 42 mounted in the elongate pole 41. Preferably, the magnet 42 of each of the magnetic units 4 is a strong magnet and presents various shapes. Preferably, the elongate pole 41 of each of the magnetic units 4 is made of plastic or wood material and has a length smaller than or equal to a width of each of the mounting sleeves 13 of the shading unit 1. In assembly, the elongate pole 41 of each of the magnetic units 4 is inserted through an open end of one of the mounting sleeves 13 into the one of the mounting sleeves 13 of the shading unit 1. In addition, the magnets 42 of the magnetic units 4 correspond to and align with each other so that the magnetic units 4 are magnetically attracted mutually.
As shown in FIG. 2, the elongate pole 41 is a hollow tube for receiving the magnet 42.
As shown in FIG. 3, the elongate pole 41 has a substantially
U-shaped profile for receiving the magnet 42, and a film 43 covers a periphery of the elongate pole 41 after the magnet 42 is placed into the elongate pole 41.
As shown in FIG. 4, the elongate pole 41 is a substantially C-shaped tube for receiving the magnet 42, and a film 43 covers a periphery of the elongate pole 41 after the magnet 42 is placed into the elongate pole 41.
Referring to FIGS. 5-7, the magnetically attractive shade assembly further comprises an adjusting clamp 6 secured on the metallic unit 5 to adjust the shade cloth member 10 of the shading unit 1 to a folded state or an expanded state.
In operation, when the magnetically attractive shade assembly is to be mounted on an object, such as a door, a window frame or the like, the first tubular portion 11 of the shade cloth member 10 of the shading unit 1 is mounted on a transverse pole of the object, so as to attach the shading unit 1 of the magnetically attractive shade assembly to the object. Alternatively, the bonding strap 21 of the connecting unit 2 is bonded onto a Velcro closure of the object, so as to attach the shading unit 1 of the magnetically attractive shade assembly to the object.
