Description

[Detailed description of the invention] This invention is a method for installing screen doors, doors, etc., which are attached to the entrance frame of back doors, entrances, etc., with an adjustable frame, by moving the adjusting frame up and down to open the empty space above the entrance frame. Insect nets and sheets can be easily stretched under tension.

The width of entrances such as back doors and entrances is almost standard, but the height varies, so if a frame is attached to a screen or door that is made to a standard, the installation must be done using a frame. There is often a void at the top.

Therefore, it is preferable to use a frame with an adjustable frame to cover the empty space.

However, in the past, there have been installation methods in which an adjustment frame is provided at the top of the frame and a shielding sheet is stretched over the adjustment frame according to the height of the entrance, but in the conventional method, the sheet is cut for each adjustment frame surface. Since the cables were stretched over the pipes, they had the disadvantage of requiring a great deal of trouble and effort to install.

The present invention eliminates the above-mentioned disadvantages and makes it possible to easily tension the sheet after operating the adjustment frame.

Now, as an example, the case where it is attached to the back door is described below with reference to the drawings.The rectangular installation with the screen door attached to the entrance frame 5 which is cut out from the pillar and the upper crosspiece is the upper surface of the upper end horizontal frame 1' of the frame 1. A groove H into which the ridge P is fitted is formed, and support frames 2' are provided opposite to each other on the left and right inner sides of the lower surface of the upper crosspiece of the entrance frame 5, and a horizontally long winding tube 4 is installed between the upper ends of these support frames. The shaft is mounted via each horizontal shaft 3 with a spiral spring S inserted inside both ends, and the lower end is attached to the outside of each support frame.The groove hole M provided at both ends of the horizontal frame 1' at the upper end of the frame 1 Insect-proof net N is inserted into the upper part of each adjustment frame 2 and is wound up and down on the winding tube 4 so as to be able to move up and down.
The drawer ends of the frame 1 are attached tightly by fitting grooves H and ridges P provided on the upper surface of the horizontal frame 1' at the upper end of the frame 1. It shows a band-shaped gap closing piece that is more effective than rubber etc. attached along the outside.

The present plan has been configured as described above, so if you want to install the present plan on the entrance frame 5, which is the back door, first install the screen door in the frame 1.
After fitting into the entrance frame 5, the adjustment frame 2 is installed between the upper end of the frame and each horizontal frame at the upper end of the entrance frame with the adjustment frame 2 reduced to the maximum extent with respect to the support frame 2'. When the support frame 2' is fixed to the entrance frame 5, the insect screen N is pulled against the helical spring S. When the drawer is pulled out and the end of the drawer is attached to the surface of the fitting groove H provided in the horizontal frame 1' at the upper end of the frame 1, the insect screen N is in a tensioned state when the push-in edge P is fitted into the fitting groove. It is stretched to

As described above, this project is installed by installing an adjustable frame with an automatic winding tube with an insect screen or sheet wound around the top of the frame, so you can move the adjustable frame up and down according to the height of the entrance and pull out the insect screen or sheet. Since it can be tightly stretched by itself, the installation of the conventional entrance frame requires the troublesome work of cutting insect screens or sheets for each cavity at the top of the frame and then stretching them. It has the advantage that it can always be stretched neatly and under tension without the risk of wrinkles or sagging, and the attachment with an adjustable frame is a simple and useful idea for the frame.
