Abstract
Description
- The present disclosure relates to a roll-up screen, and in particular, relates to a roll-up screen that can be positioned anywhere.
- Buildings are provided with a number of windows allowing outdoor sunlight and air to enter rooms from the windows. In order to prevent outdoor mosquitoes and flying dust from entering the rooms, many windows will add another screen to prevent mosquitoes and flying dust from entering the rooms. Therefore, the use of the screens has become one of the devices that must be set up at present. Most current screens are flat structures. When the flat screens are installed on the windows, the line of sight looking out of the window will be blocked. In order to improve the problem, many people have switched to roll-up screens instead of the flat screens. With a scrolling function of the roll-up screen, when you do not use the screen, the screen can be hidden on one side of the door and window, so as to improve the problem that the flat screen can easily obstruct the view of the beautiful view from the window.

FIGs. 1 and2 , a conventional roll-upscreen 1 is disclosed, which mainly includes a roll-up unit 11, amesh screen 12 and ahandle 13. The roll-upunit 11 has at least onerotary shaft 14, and both ends of themesh screen 12 are respectively fixed to thehandle 13 and therotary shaft 14. When themesh screen 12 is to be folded, therotary shaft 14 can be rotated, and themesh screen 12 can be retracted on therotary shaft 14, so that themesh screen 12 no longer obstructs the view of the window. In addition, when themesh screen 12 is to be unfolded, thehandle 13 can be pulled away from the roll-upunit 11 to enable themesh screen 12 to be unfolded, thereby achieving the desired benefit of preventing mosquitoes from entering the room. - However, the roll-up screen can be rolled up without blocking the window and preventing mosquitoes from entering the room. It is found that when the
mesh screen 12 is unfolded, thehandle 13 cannot be randomly positioned with the position where themesh screen 12 is deployed, which is inconvenient to use. Therefore, after using themesh screen 12 of the conventional roll-up screen, it is necessary to add ahook 15 on the window (as shown by the imaginary line inFIGs. 1 and2 ). After themesh screen 12 is unfolded, abuckle 16 on thehandle 13 can be hooked on thehook 15 of the window, so that themesh screen 12 is not retracted, and thehooks 15 and the buckle not only increases the cost but also has the trouble of installation and labor. - The present disclosure mainly solves the problem of the prior art, which is that a handle cannot be arbitrarily positioned according to the position where a mesh screen is unfolded, and the structure is also costly and time consuming to install.
- An object of the present disclosure is to provide a roll-up screen, the roll-up screen includes two side frames disposed at an interval, a roller mechanism disposed between the side frames, a mesh screen configured to be wound in the roller mechanism and pulled out to expand therefrom, a handle disposed at one end of the mesh screen, and two positioning wires disposed on the side frames, wherein the two positioning wires pass through the handle, and both of the two positioning wires are provided with a screen positioning device, respectively. The tension of the two positioning wires is adjusted by the screen positioning device, so that the handle can be arbitrarily positioned between the two side frames, so that the mesh screen can be positioned anywhere.
