Description

[Detailed explanation of the idea] The present invention relates to a roll-up screen door.

In particular, it relates to a screen door whose opening and closing are performed in conjunction with the opening and closing of a sash.

Traditional screen doors are made by stretching a screen over a screen door frame.

Therefore, even when the window is closed, the screen door occupies half of the window frame, which not only interferes with the transparency of the window glass, but also poses a risk of damage.

The present invention is designed so that when the window is closed, it is wound around a net winding rod, and when the window is opened, it is linked with the opening movement of the window sash, so that the net is stretched by the amount that the window sash is opened.An example will be described below. .

Reference numeral 1 denotes a net winding rod, which is rotatably attached between an upper bracket 2 and a lower bracket 3, and around which a net 4 is wound.

The upper bracket 2 and the lower bracket 3 are fixed to a height-adjustable screen door fixture 5 by a fixing member 6.

The screen door defining tool 5 has grooves 8a at its upper and lower ends for inserting and fixing into the existing screen door rails 7a and 7b in the upper frame A and lower frame B,
8b.

9 is a height adjustment screw for the screen door fixture 5.

In this part, the screen door fixture 5 is connected to the upper outer female member 5a,
It is composed of a lower inner male member 5b, both of which fit into a nesting hole.

A long hole 10 is provided in the male member 5b, and is tightened with a screw 9 after adjustment.

3a (FIG. 3) is a narrow recess provided in the lower bracket 3, in which the lower part of the mesh rod 1 is pivotally supported.

11 is a thrust bearing, and 12 is a spring fixed shaft, which are fixed to the bottom of the dish-shaped recess 3a.

Reference numeral 13 is fixed by a spring to the fixed shaft 12 at one end and to a rotary table 14 supported on the spring fixed shaft 12 at the other end.

Two parallel angles 15, 15 are fixed to the upper part of the rotating table 14 and engage with a pin 16 fixed to the lower end of the wire rod 1.

The rotary table 14 is rotatably supported by a spring fixed shaft 12 at the center and a thrust bearing 11 at the periphery.

Therefore, when the winding table 1 is rotated, the rotating table 14 rotates via the pin 16 against the bias force of the spring 13.

At this time, the load applied to the rotary table is carried by a thrust bearing 11 so that the rotary table rotates smoothly.

The upper part of the mesh rod 1 is loosely fitted into an opening 17 provided in the upper bracket 2 (FIG. 5).

The net 4 is fixed to one end of the net winding rod 1, and the other end is fixed by a presser 21 to a groove 20 provided in a fixture 19 fixed to the vertical stile 18 of the sliding door, as shown in FIG.

Furthermore, 22 (Fig. 1) indicates the upper and lower screen door rails 7a and 7b.
With the notch at the end, the screen 4 is stretched between the screen rod 1 and the fixture 19 fixed to the sliding door, and between the sash rail and the screen door rail via the notch 22.

In this case, in order to make it easier for the net 4 to pass through, the notch 22 is cut out to a considerable width, creating a gap.In order to close this gap, a thin rubber seal 24 or the like can be attached to the vertical frame 23 of the window using double-sided tape or the like. Yes (Figure 7).

With the above configuration, the net 4 is wound around the net winding rod 1 when the window is closed.

When the sliding door to which the screen 4 is fixed is opened when a screen door is desired, the screen 4 is pulled against the spring 13 and the screen 4 covers the opened part of the sliding door.

On the other hand, when the sliding door is closed, the net 4 is constantly pulled by the spring 13 and is smoothly wound around the net winding rod 1.

According to the present invention as described above, (1) it can be easily attached to existing window sashes;

(2) Since the groove of the window screen rail is used, no special guide is required.

(3) Since it is easy to install and remove, it can be removed and stored when not in use during the winter.

(4) Since the net is wrapped around a net winding rod, there is no risk of the net being damaged during storage or when not in use.

(5) The screen and the edge of the screen door fixture come into contact each time the window is opened or closed, making it difficult for dust to adhere to it.

(6) Since the net winding rod can be easily removed from the bracket, when the net becomes old, it is easy to replace only the net.

(7) It is convenient because the opening and closing of the screen door is linked to the opening and closing of the window.
