BACKGROUND OF INVENTION
Field of Invention
The present invention relates to a shielding structure, and more particularly to hanging blinds.
Description of the Related Art
Usually, windows are equipped with curtains to maintain or change the lighting and shading of the windows. When the outside lighting is too strong or privacy is required, the curtains can be for change. There are many different structures and styles of curtains, such as hanging curtains, roller shutters, blinds or roman curtains, etc. But the basic purpose of curtains is nothing more than to be able to block light and to ensure privacy, it is also necessary to be able to control the appropriate light to enter the room.
For conventional vertical curtains structure, as shown in FIG. 12, the curtain structure 40 includes a support base 41; a plurality of slide rails 42 arranged side by side on the support base 41; a plurality of rail rods 43 are respectively arranged on each slide rail 42, the upper ends of these rail rods 43 are all respectively provided with two pulleys 431 mounted in the slide rails 42; a plurality of curtains 44 connected to the rail rods 43; and a pull cord 45 disposed on the support base 41 and capable of driving the rail rods 43. Furthermore, the rail rods 43 are respectively provided with a plurality of positioning blocks 432 staggered to limit the movement between the sliding bases 13.
According to the above-mentioned conventional structure, it is not difficult to find that there are still some deficiencies. The main reasons are as follows: the plurality of rail rods 43 of the conventional curtain structure 40 are respectively set on the sliding rail 42 of the support base 41 through the pulley 431, such that the number of the slide rails 42 of the support base 41 must be increased in sequence according to the number of the slide bars 43, thereby increasing the size and volume of the support base 41, which resulting in an increase in the manufacturing cost, the packaging and the assembly difficulty of installation of volume of the support base 41.
Therefore, it is desirable to provide hanging blinds to mitigate and/or obviate the aforementioned problems.

An objective of present invention is to provide a hanging blinds, which is capable of improving the above-mention problems.
In order to achieve the above mentioned objective.
Other objects, advantages, and novel features of invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
First, please refer to FIG. 1 to FIG. 6. Hanging blinds comprises an upper track 10 and a plurality of sliders 20. The upper track 10 has a first track 11 and a second track 12, and the first and second tracks 11, 12 both respectively comprising a sliding slot 111, 121 and an opening 112, 122 connected to the sliding slot 111, 121. The first and second tracks 11, 12 are parallel with each other. Each slider 20 has a guiding groove 21 and a positioning groove 22. A sliding block 23 is disposed at an end of the positioning groove 22 and enabling the slider 20 to be slidably mounted onto a guiding groove 21 of an adjacent slider 20. A stopping block 24 is mounted on a front end of the guiding groove 21. Each slider 20 being mounted onto a respective one of the sliding slots 111, 121 of the first and second tracks 11, 12. A last slider 20 on the second track 12 has at least two positioning blocks 25 at a top thereof locking with an end of the second track 12, and the sliders 20 other than the last slider 20 each has a pulley 26 slidably mounted in the sliding slots 111, 121 of the first or second tracks 11, 12. The last slider 20 on the first track 11 further has a crossing pulley 27 mounted in the sliding slot 121 of the second track 12, and the crossing pulley 27 is disposed before a pulley 26 of a first slider 20 on the second track 12.
Furthermore, the first and second tracks 11, 12 of the upper track 10 are respectively assembled in telescope manner, which provides an adjustable length.
Moreover, each slider 20 is connected to a curtain 30.
In addition, each slider 20 on the first track 12 has two pulleys 26.
Also, the first slider 20 on the first track 11 is provided with a pulling rod 28.
The actual operation of the above mentioned structure, please refer to FIGS. 3, 7, 8, and 9. The sliders 20 are mounted both on the first and second tracks 11, 12 of the upper track 10 and the upper track 10 is installed above a desired window. The bottom of each slider 20 is attached with a curtain 30 to cover the window. When a user wants to unfold the curtain 30, he or she pulls the pull rod 28 to slide the first slider 20. When the first slider 20 is pulled out, it not only slides along the sliding slot 111 of the first track 11, but also moves the sliding block 23 along the guiding groove 21 of another adjacent slider 20, so that the sliding block 23 pushes against the stopping block 24 at the front of the guiding groove 21 and then pulls out the other sliders 20. Also, the last slider 20 on the first track 11 is also slidably installed in the guiding groove 21 of the first slider 20 on the second track 12 via the sliding block 23, so that the sliders 20 on the second track 12 can be pulled out in sequence so the window is covered by the curtains 30.
Conversely, in order to collect the curtains 30 back together, please refer to FIGS. 7, 10, and 11 again. The user uses the pull rod 28 to push the first slider 20 on the first track 11 backward, the slider 20 is pushed and slides back along the first track 11 via the pulley 26, the pulley 26 pushes back an following pulley 26 to move the adjacent slider 20 and so on until the last slider 20 on the first track 11 is pushed back. Then, the crossing pulley 27 abuts the pulley 26 of the first slider 20 on the second track 12, thereby the sliders 20 on the first and second tracks 11, 12 are pushed back in order, so that all the curtains 30 are pushed back to the ends of the first and second tracks 11, 12 to be gathered together.
With the structure of the above-mentioned specific embodiment, the following benefits can be obtained: the hanging curtain structure of this present invention has a plurality of sliders evenly and respectively mounted into the first and second tracks 11, 12, and the first and second tracks 11 and 12 are set independently and arranged in parallel. The curtain structure can be adjusted by increasing or decreasing the number of slide tracks according to the size of the window. The tracks 11, 12 equally shares the weight of the sliders 20 and the curtains 30, which avoids the deformation of the upper track 10 and thereby improving the travel smoothness of the slider 20.
In addition, the last slider 20 on the first track 11 is provided with the pulley 26 and the crossing pulley 27, so that the last slider 20 is capable of sliding between the first and second tracks 11 and 12 at the same time, which helps to improve the sliding stability of the slider 20. Also, the pulley 26 of the last slider 20 on the second track 12 is pushed by the crossing pulley 27, to make linkage among the sliders 20 between the first and second tracks 11 and 12.
Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
