Description

[Detailed Description of the Invention] This invention relates to a screen door, and particularly relates to a screen door that can be retrofitted to a window that can be opened and closed with a shoji extending outward from the room.

It may become necessary to later attach a screen to an existing window such as a sliding window or a casement window where a shoji screen opens and closes to the outside. For windows where the shoji opens and closes to the outside, a screen must be installed on the indoor side of the window so as not to interfere with the opening and closing of the shoji. Must be possible.

This idea solves these problems all at once, and can be retrofitted to existing windows with simple installation work.
Another object of the present invention is to provide a screen door with a partially opening/closing screen portion that is inexpensive and has a good appearance.

Next, an example will be explained.

The figure shows one embodiment of the invention. Fig. 1 is a front view of the screen door according to this invention, Fig. 2 is a vertical cross-sectional view of the screen door attached to the sliding window, and Fig. 3 is the screen door with the screen door attached. FIG. 4 is a cross-sectional view of the main body, FIG. 4 is a cross-sectional view of the movable net unit, and FIG. 5 is a vertical cross-sectional view of the movable net unit in a connected state.

The retrofitted screen door according to this invention is composed of a screen door main body 1 having a movable screen portion, and upper and lower screen door frames 3 and 4.

The screen door main body 1 has a movable screen portion 2, and is fitted into screen door frames 3 and 4 attached to a frame, which will be described later. The screen door body 1 has an upper stile 11, left and right stiles 12, 13, and a lower stile 14 as a square frame, and a middle stile 15 is passed horizontally between the left and right stiles 12, 13. A net material 16 is attached to a first opening formed in a rectangular shape by a middle crosspiece 15 to form a fixed net portion. The length between the upper and lower stiles 11 and 14 is made somewhat smaller than the height between the lintel of the frame and the window sill, which will be described later, and the width between the left and right stiles 12 and 13 is the same as the length between the left and right columns.

The upper stile 11, the left and right stile 12, 13, and the lower stile 14 are all made of the same material, and a screen door mounting portion 18' having a generally T-shaped cross section is formed over the entire length of the columnar portion 18 having a generally rectangular cross section. Cage, upper stile 11, left and right stile 12, 1
3. The screen door mounting portion 18' is positioned on the inner peripheral edge formed by the lower stile 14 in a rectangular shape.

The middle frame 15 of the screen door body 1, the left and right vertical frames 12, 13,
A movable net unit 2 is attached to a second opening formed into a rectangular shape by a lower stile 14. A screen door mounting portion 18' having a substantially T-shaped cross section formed on the inner peripheral edges of the left and right vertical stiles 12, 13 and the lower stile 14 is cut out to form a screen door storage portion. Movable net unit 2
This is a member in which an upper stile 21, left and right stiles 22, 23, and a lower stile 24 are assembled into a rectangular stile and a net material 25 is stretched. The length between the upper and lower frames 21 and 24 of the movable screen unit 2 is approximately the same as the length between the opposing surfaces of the middle frame 15 and the lower frame 14 of the screen door body 1, and
The length between the three spaces is approximately the same as the length between the opposing surfaces of the left and right frames 12 and 13 of the screen door body 1.

Frames 21, 22, 23, 24 of movable net unit 2
When assembled, a connecting block 26 is housed in each joint at the corner of the square, and the joints are joined at a 45 degree angle. The connecting block 26 is a member in which two L-shaped sliding surfaces 28 are provided parallel to and symmetrically on both sides of the joint surface 27, and the joint surface 27 is connected to the left and right vertical frames 2.
The sliding surfaces 28 are tightly fitted and joined to the upper and lower frames 21 and 24 and the left and right vertical frames 22 and 23, respectively. The support bolts 51 are inserted through the holes 17 of the left and right frames 12 and 13 of the screen door body 1, pass through the surfaces of the left and right frames 12 and 13 on the side of the movable net unit 2, and protrude in directions facing each other, thereby forming a rectangular movable screen door. Connecting wall 29 serving as the outer peripheral end surface of the four circumferences of No. 2
The connecting block 26 is inserted through a hole 30 formed in the connecting block 26, and is screwed and fixed to the joint surface 27 of the connecting block 26. Joint surface 2
A female thread is cut into the hole 7, to which the movable net unit 2 is connected, and the second opening serves as a movable net portion.

The upper and lower screen door frames 3 and 4 are members for folding the screen door, and are linear members with a U-shaped cross section. The lengths of the upper and lower screen door frames 3 and 4 are made to match the spacing between the left and right pillars of the frame, which will be described later. Next, we will explain how to install the screen door.

The screen door is attached to the existing window frame 6.
The frame 6 includes a lintel 61, left and right pillars 62, 63, and a window sill 6.
4 is assembled into a square shape, with an upper frame 71 and left and right vertical frames 7.
2, 73 and a lower frame 74 are framed in a square window frame 7
is attached and an opening is formed. window frame 7
A known opening/closing body 8 such as a sliding shoji or an opening shoji is installed inside.

The upper and lower frames 3 and 4 for the screen door are fixed to the lintel 61 and the window sill 64 of this frame 6 by screwing them vertically facing each other. The screen door upper and lower frames 3 and 4 are installed on the indoor side of the window frame 7, and in positions where they do not come into contact with the handle 81 when the handle 81 is provided on the opening/closing body 8.

The screen main body 1 is folded into the upper and lower frames 3 and 4 for the screen door with the movable screen unit 2 facing downward.

The opening/closing body 8 is opened and closed by opening the movable net unit 2.

Even if the screen door can only be attached to a position where the handle 81 contacts the screen door when the opening/closing body 8 is tightened, it will not come into contact with the handle 81 when the movable screen unit 2 is opened.

This invention has the above configuration and can obtain the following effects.

The installation process is as simple as attaching a pair of support frames for installing screen doors to the existing window and fitting them into the frame.
A screen door can be added to existing sliding windows, casement windows, and other windows where shoji screens open and close to the outside.

Without using hinges, the movable screen unit is pivoted to the pair of frames within the frame by means of support bolts that are fixed to the connecting blocks of the movable screen unit, and the pivots are not visible from either the inside or the outside. The structure has a very good appearance, and by using a structure that uses connecting blocks without using hinges, this type of screen door, which tends to be expensive, can be provided at a low price. .
