JPS6017494Y2 - Satsushi entrance with screen door - Google Patents

Description

[Detailed description of the invention] This invention relates to the structure of installing a screen door in an entrance satsushi with a screen door.

The purpose is to propose a sliding door window with a screen that can be easily opened and closed.

Conventionally, some sliding windows are provided with a screen door that slides in parallel to open and close.

However, I can't find any sliding entrance windows that have a screen sliding part.

Further, when a screen door is attached to an entrance sliding window that has the same structure as a conventional sliding window and is frequently accessed and accessed, the screen door cannot be opened and closed easily.

In other words, the conventional screen door rests on the rail of the lower frame of the sash, and the upper end fits into the sliding groove of the upper frame to slide open and close. Therefore, in entrances and other areas where there is a lot of traffic, obstacles such as dirt can adhere to the rail, making it difficult to compare. This is because a lightweight screen door will be difficult to open and close easily, and in some cases may come off the sash frame.

This invention was made with attention paid to the above-mentioned problems.

The gist is a sash frame made up of upper and lower frames and left and right vertical frames in a rectangular shape, the above-mentioned upper frame of the entrance sash with a sliding door attached inside, a screen door rail on the indoor side, and an upper frame on the screen door rail. The hanging screen door 7 is slidably suspended by a door wheel attached to the upper stile of the screen door, and a sliding piece is provided on the lower stile of the screen door, and the sliding piece is provided between the indoor floor surface and the upper surface of the lower frame of the sash. It is characterized by hanging between the stepped wall and the sliding door on the indoor side.

Hereinafter, an explanation will be given with reference to an example of the illustrated entrance sliding window.

In FIGS. 1 and 2, two sliding doors 2 are attached to a sash frame 1 provided in an opening, forming a sliding door.

An upward rail 4 made of a band-shaped plate bent into a cross-sectional shape is attached to the indoor side of the upper frame 5 of the sash frame 1, and a door wheel 9 attached to the outdoor side of the upper stile 5 of the screen door 7 is mounted. It is placed.

Further, a sliding piece 11 is attached to the lower stile 10 of the screen door 7, and extends toward the outside and has a tip end shaped like an angular cross-section.

This sliding piece 11 is bent so that it can be placed along the step wall 20 between the indoor floor 18 surface and the upper surface of the sash bottom frame 5, and its tip is between the sliding door rail 19 and the step wall 20 surface. , and can slide freely along this gap.

In this invention, the rail 4 may be formed integrally with the upper frame 3, or may be formed separately from the upper frame 3 and attached thereto.

In addition, in the above-mentioned embodiment, a total of two screen door wheels are generally installed near the left and right stile.

This idea is as described above, and brings about the following effects.

Since the screen door slides while being suspended from the rail attached to the top frame of the sash, compared to the conventional screen door that slides on the rail of the bottom frame, it is more susceptible to obstructions such as dirt adhering to the rail and the rail being exposed to external force. It is unlikely to be deformed or damaged, and the screen door can be easily slid open and closed.

This is particularly effective in openings that are frequently accessed and exited, such as entrances.

Furthermore, the lower stile of the screen door is equipped with a sliding piece that hangs down between the step wall and the sliding door on the indoor side, so even if a strong wind blows while the sliding door is open for ventilation, This prevents the lower part of the top-hung screen door from swinging and causing the door roller to fall off the rail.

Further, at this time, it is not necessary to form a special guide piece on the lower frame.
