Description

  The present invention relates to a roll-up screen device that facilitates screen replacement and a screen replacement method in the device.

Conventionally, one end of the screen is fixed to a slidable movable rod on the screen frame, and the other end of the screen is fixed to a winding shaft that is rotated by a biasing force of a spring in the winding box. A winding screen device in which the screen is wound around a winding shaft is generally well known, without needing to be particularly exemplified. In this type of screen device, when the screen is torn, torn, etc., or becomes dirty due to long-term use and it is necessary to replace the screen, generally, the entire take-up shaft around which the screen is wound is replaced. Or, it was handled by replacing the entire take-up box. However, in these methods, members other than the screen that do not need to be replaced are also replaced, which is not only wasteful but also increases the cost for replacing the screen. It was.
Thus, it is possible to replace the screen by the user, but in that case, even if the existing screen can be removed from the take-up shaft, a new screen can be attached to the take-up shaft. It is necessary to attach the screen to the winding shaft so that the screen does not become wrinkles, and it is necessary to adjust the urging force of the winding spring. In this way, it was extremely difficult for the user himself to replace only the screen.

  In addition, it is possible to exchange only the screen by sending the above screen including the winding shaft or winding box to the manufacturer, but it is not only troublesome to remove the winding shaft and send it to the manufacturer. However, it has been pointed out that it takes time and money to exchange and return the screen.

On the other hand, although there is a method in which a general user can replace only the screen, in the conventional replacement method, it is necessary to remove only the screen from the installed screen device. Depending on the installation conditions of the installation location, it may be difficult to replace the screen.
That is, when removing only the screen from the existing screen device, it is necessary to remove the screen from the movable rod and the winding shaft to which the tip and the base end of the screen are fixed, respectively. It can be installed in a place under various installation conditions such as a building opening in a narrow space, and the screen is removed from the existing screen device installed in such a place. Performing in a space under limited conditions around the device is not only difficult for general users, but it can be dangerous, and it requires a lot of skill and is not always easy. It was not a method that could be replaced.
