Two-way opening and closing curtain improved structure

This creation relates to a curtain structure, and in particular to an innovative structural type designer of a two-way opening and closing curtain.

Press, usually the windows in the home or workplace will be set up with curtains (such as roller blinds, curtains, Roman blinds, venetian blinds, etc.), in addition to avoiding the light shining through the window into the room, it can prevent others from peeking from the outside. However, the conventional curtains usually control the curtain lifting by a pull rope to achieve the shielding effect, but at dusk, the sunlight will only enter the room from the bottom end of the window in a low angle mode, if the curtain is lowered to the minimum. At this point, the entire window is covered and the problem of dim and poor ventilation in the room is caused. In view of this, a manufacturer has developed a two-way opening and closing curtain to cope with it.

The end 03 is used to adjust the retracting state of the curtain body 04. However, the conventional structural type has found that the following problems still exist in the actual use experience: as shown in FIG. 1, when the user pulls the bottom end 03, When the curtain body 04 is unfolded to the lowest point, it tends to exert a downward force on the bottom end 03 due to the homeopathic or ensuring that the curtain body 04 can no longer continue to expand. However, due to the conventional activity top end 02, the curtain body 04 and the bottom end 03 In order to connect to each other, when the curtain body 04 can no longer be deployed, if the user pulls down the bottom end 03 again, the curtain body 04 is pulled and the movable top end 02 is moved downward, resulting in the fixed top seat 01 and the activity. A gap is created between the top 02 (shown as H in the figure) and the barrier effect is lost. Causing the user needs more time to adjust distress and inconvenience of the program.

Therefore, in view of the problems existing in the above-mentioned conventional two-way opening and closing curtain structure, how to develop an innovative structure that is more ideal and practical, is expected by the users, and is also related to the industry's efforts to develop breakthrough goals and directions.
