Description

[Detailed explanation of the idea] The present invention relates to a screen door for a sliding entrance door.

Like window sashes, entrances are also desired to have screens for insect protection, ventilation, prevention of intrusion by dogs and cats, prevention of children jumping out, etc.

However, it was difficult to install a screen on the entrance sliding door due to its structure, and it was difficult to achieve a good appearance, so those with a screen were not commonly used.

The purpose of the present invention is to provide a screen door for an entrance sliding door that can be installed on the sliding entrance door in a good manner, does not rattle or come off, and can be easily installed on the existing sliding entrance door.

Embodiments of the present invention will be described below with reference to the drawings.

1 is the entrance sliding door, 2 is the upper frame, and 3 is the lower frame rail.

The lower frame rail 3 is fixed to a foundation 5 via anchors 4.

In the embodiment shown in FIG. 1, the rising wall 6 of the lower frame rail 3 protrudes from the finished surface 7 of the entrance dirt floor, and this rising wall 6 is used as the rail for the screen door A.

A guide member 8 is attached to the inside of the upper frame 2 with screws 9, and the upper frame 10 of the screen door A is fitted into this.

A door roller 12 provided on the lower stile 11 of the screen door A is placed on the rising wall 6.

The lower end 13a of the outer wall 13 of the lower stile 11 is in slight sliding contact with the upper surface of the lower frame rail 3.

Also, a guide flange 14 facing horizontally on the outer wall 13
is projected, and this guide flange 14 enters the gap between the lower stile 15 of the entrance sliding door 1 and the rail member 3a of the lower frame rail 3, and the tip 14a of the guide flange 14 is inserted into the protrusion 3a' of the rail member 3a. It is in slight sliding contact with the

Note that a gap may be left between the lower end 13a of the outer wall 13 and the lower frame rail 3, and between the tip 14a of the guide flange 14 and the protrusion 3a'.

As mentioned above, by using the gap between the lower stile 15 and the lower frame rail 3 of the entrance sliding door 1 as a guide groove for the guide flange 14 of the screen door lower stile 11, the screen door A can be moved in the vertical direction and the front-back direction (in the opening/closing direction). There is no wobbling in the direction perpendicular to the
Smooth opening/closing operations are possible and the screen door is prevented from coming off.

FIG. 2 shows another embodiment of the present invention, in which a sliding member 16 made of a material with a small friction coefficient such as a hard synthetic resin is attached to the lower end 13a1 of the outer wall 13 of the lower screen stile 11 and the tip 14a of the guide flange 14. 17 is attached.

One sliding member 16 is connected to the upper surface of the lower frame rail 3 and the rising wall 6.
The other sliding member 17 is in contact with the inner surface of the rail member 3a.
It is in contact with the upper surface of and the side surface of the protrusion 3a'.

This completely restricts the movement of the screen door in the vertical and longitudinal directions, and the door roller 12 accurately moves on the rising wall 6 without swinging back and forth.

Therefore, in this embodiment, the finished surface 7 of the earthen floor is the rising wall 6.
Even when the door roller 12 is constructed flush with the dirt floor, the door roller 12 can be moved smoothly without protruding into the dirt floor.

In the embodiment shown in FIG. 1, the same effect can be obtained if the lower end portion 13a and the tip portion 14a are brought into sliding contact with the lower frame rail 3 and the protruding portion 3a', respectively, but in this case, the sliding becomes somewhat worse.

As described above, according to the present invention, insect prevention, ventilation, and safety can be improved by providing a screen door on the sliding entrance door, and a guide flange is provided on the lower stile of the screen door to connect the lower stile and the lower frame of the sliding door. Since it is placed in the gap between the rails, the screen door can be opened and closed smoothly without rattling, and it is also possible to reliably prevent the screen door from coming off.

Furthermore, the bottom rail of the sliding door can be used as the rail of the screen door)
Since it can be used for both purposes, there is no need to add a special rail for the screen door, and it can be easily installed on the existing entrance sliding door, and the screen door can be installed neatly and neatly.
