Description

Roll screen device

The present invention relates to a roll-screen apparatus for use in a window frame, which comprises an insect screen for blocking pests and a light-shielding film for blocking sunlight, and optionally an insect screen or a light-shielding film can be selectively used.

Conventionally, a general window is equipped with a window frame on a wall, and a window and an insect control window are installed on the window frame in a double structure, and a blind or a curtain is additionally provided in order to provide means for intercepting sunlight.

Also, in order to solve the problem of installing separate blinds or curtains, a method of incorporating blinds between the double glazed windows has been proposed. However, this technique is applied only to very expensive models, and the installation cost is excessively high. There is a problem that maintenance is difficult when the blinds provided are broken.

Meanwhile, recently, there has been proposed a system in which a window is installed in a window frame to block a pest or implement a shading function.

For example, a structure disclosed in Korean Patent Registration No. 1328268 has an insect-control net that is opened and closed by a roll system, and the insect-control net can be used as a light-shielding state in a state where the insect control net is halted as needed. However, Since the shielding function is very weak due to the shielding using an insecting net, the insecting net must be made compact in order to improve the shielding function. In addition, there is a problem that the ventilation is not properly performed when the insecting net is made dense, There is a problem that pests are infiltrated into the remaining open space.

Korean Patent Registration No. 1308759 proposes a cold weather roll screen structure which is opened and closed by a roll system. However, since this system simply opens and closes a blocking member, a separate screen net must be installed in order to simultaneously perform shading and insect blocking And there is an inconvenience that the user must replace the blocking member according to the seasonal purpose of use.
