Description

[Detailed Description of the Invention] The present invention relates to a folding screen door that can be attached to a doorway, etc. by adapting it extremely easily to the width of the doorway, etc.

Recently, there have been seen folding screen doors in which a flexible insect screen is stretched between vertical frames to form the screen main body, and runners are attached to the upper end of the screen main body at predetermined intervals.

The present invention aims to improve this folding screen door from the following viewpoints.

In other words, since the width (width between vertical pillars) of the doorway to which the folding screen door should be attached differs from house to house, pre-fabricated and sold folding screen doors can be attached to doorways with different widths. It must be possible to adapt and install it accordingly.

For this reason, with conventional folding screen doors of this type, the purchaser measures the width of the doorway, etc., and cuts the insect screen to correspond to this length.
After that, an insect screen is attached to the vertical frame using a net presser.

However, such work is troublesome, and there is a risk that the insect screen may be too loose or too tight between the vertical frames, and the insect screen may become bent or wrinkled due to too much slack between the top and bottom frames. many.

In view of the above, the present invention has been developed in such a way that one of the vertical frames 1 has a rotary cylinder 3 in its inner hollow part 2 extending from the upper part to the lower part, and is rotatable while maintaining a distance from the inner circumferential side surface 4 of the inner hollow part 2. The insect screen 6, which has one end attached to the other vertical frame 5, has its other end inserted into the internal hollow part 2 from the insertion lower extending from the upper part to the lower part of the one vertical frame 1. The main body of the screen is attached to the rotary tube 3 and wound up to a predetermined width, and one of the vertical frames 1 is provided with a device 8 for rotating the rotary tube 3, and the screen is fitted into the insertion lower. This paper proposes a folding screen door that can be used with a matching screen presser 30.

Examples of the present invention will be shown below.

The one vertical frame 1 is fixed to one vertical pillar 9 of a doorway, etc., and is composed of a connecting vertical frame part 10 and a fixing vertical frame part 11 that is fitted and connected to the vertical frame part 10. There is.

The other vertical frame 5 serves as a pull handle, and is composed of a connecting vertical frame 12 and a pull vertical frame part 13 that is fitted and connected to the connecting vertical frame 12.

Further, a centering cap 15 having a loose through hole 14 in the center is fitted and attached to the upper end of one of the vertical frames 1.

A shaft portion 17 of a rotating dial 16 loosely passes through this free through hole 14, and this rotating dial 16 is attached to a fixing screw 18.
is fixed to the upper end of the rotary cylinder 3.

The device 8 for rotating the rotary cylinder 3 is this rotary dial 1
6, and the rotary cylinder 3 is formed by a rotary dial 16.
Rotate by rotating.

Further, the rotary cylinder 3 is composed of a male part 19 and a female part 20, and the insect net 6 is attached to the rotary cylinder 3 by fitting the male part 19 and the female part 20.

In addition, in the figure, 21 is the edge of the upper and lower ends of the insect screen 6, 22 is a support frame attached to the main body of the screen at a predetermined interval, and 23 is attached to the support frame 22 and the other vertical frame 5, respectively. 24 is the rail of the runner, 25 is a shielding device attached to the rail 24 to block pests from entering through the gap between the upper end of the main screen door and the rail 24, and 26 is the vertical rail of the other vertical frame 5. The presser foot 27 is a closing magnet attached to the other vertical frame 5, and 28 is a suction plate corresponding to the closing magnet 27, which is attached to the vertical column 29.

The foldable screen door according to the present invention has the above-mentioned structure, and when it is attached to a doorway etc., the insect screen 6 wound around the rotary tube 3 is pulled out from one vertical frame 1, and the insect screen 6 is pulled out from one vertical frame 1. 1 to one vertical post 9 of a doorway etc., and the other vertical frame 5 to the other vertical post 29 of a doorway etc., then the insect screen 6 is placed between the vertical frame 1 on one side and the vertical frame 5 on the other side. The rotary tube 3 is rotated by the device 8 that rotates the rotary tube 3 until it is stretched with an appropriate tension, and the insect screen 6 is wound up.Then, the vertical presser 30 is fitted to the insertion lower, and the insect screen 6 is By fixing it to one vertical frame 1, it can correspond to the width of a doorway, etc.

In this way, the folding screen door according to the present invention can of course be attached to doorways with different widths in each house, and the means for doing so is the device 8 that rotates the rotary tube 3. Since the rotary tube 3 is rotated to wind up the insect net 6, it is extremely easy to do, and it also prevents the insect net from being too loose between the vertical frames, or too tight, or even being too loose between the top and bottom. The material can be stretched properly without wrinkles caused by the material.
