Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a structure for attaching a screen to a louver window.

[Prior art] A louver window generally has a large number of slats mounted horizontally on a shaft so that they can be closed like an armor, and all the slats can be opened and closed at the same time using a connecting rod. A screen door is often fixed on the inside of the room to prevent the intrusion.

However, louver windows require a fairly wide range of rotation for the slats, so the projected dimensions of the window frame were made considerably wider than normal sash frames so that the slats would not support the screen.

However, when the thickness and width of the window frame is increased, the standard does not match that of normal sliding shoji windows or opening shoji windows, so the window frame material cannot be used as the louver window at the top of the above-mentioned multi-stage window, so sash manufacturing is required. It was somehow uneconomical in terms of management.

From the above point of view, the purpose of this invention is to prevent the louver slats from supporting the screen door even if the thickness and width of the window frame of the louver window are set to normal dimensions.

[Means for solving the problem] In order to solve the above problem, this invention
Upper and lower frames 19, 20 and left and right frames 21 of the screen door 5,
Projections 24, 25, and 26 are formed on the frame bodies 19a, 20a, and 21a to the outside of the room, respectively, and a projecting frame 27 consisting of upper and lower projecting pieces 24 and 25 and left and right projecting pieces 26 and 26 is used to protect the window frame F from insects. The screen 22 is supported by extending toward the indoor side, and the louver blade 4 is configured to pass through the window frame F and rotate into the projecting frame 27.

[Example] The drawing shows an example of this invention, and the louver window frame F is composed of upper and lower frames 1 and 2 and left and right vertical frames 3 and 3, each having the expected dimensions of a normal window frame. A large number of slats 4 are mounted on a shaft so that they can be closed like an armor, and a screen door 5 is attached to the inside of the room. It is nailed to a stand 8 and attached in a semi-external manner, a board 9 is installed for nailing, mortar 10 is applied to the outer wall, a decorative board 11 is pasted on the inside, and the slats 4 can be opened and closed at the same time by connecting rods 12. I'm starting to do that.

The upper and lower frames 1 and 2 and the vertical frame 3 have inner walls 13, 14, and 15 respectively projecting toward the inner side of the frame. Engagement pieces 16, 17, 18 for engaging with the tray plate 9 are provided at the base ends of the plates 14, 15, respectively, to protrude toward the indoor side.

The screen door 5 has upper and lower stiles 19, 20, left and right stiles 21,
An insect screen 22 is stretched over a frame with a frame 21, and each frame 19, 20, 21 has a frame body 19a, 20.
Projecting pieces 24, 25, 26 toward the outdoor side from a, 21a
A projecting frame 27 is formed by the upper and lower projecting pieces 24, 25 and the left and right projecting pieces 26, 26,
The frame bodies 19a, 20a, and 21a are formed hollow, and a mounting groove 23 for an insect screen 22 is provided inside the frame.

In addition, locking pieces 28 and 29 are provided to project upward from the tip of the protruding piece 24 of the upper stile 19 and downward from the tip of the protruding piece 25 of the lower stile 20. It is also long in shape. Furthermore, upper stile 19
and grooves 3 in each of the protrusions 24 and 25 of the lower stile 20.
0, 31 are provided, and a tight material is fitted into each groove 30, 31 to seal the gap with the window frame F. On the other hand, the protrusions 26, 26 of the left and right vertical frames 21, 21 are bent at the tip into an L-shape facing toward the outdoor side, and the bent portions are formed obliquely. As for the framework of the upper and lower frames 19, 20 and the vertical frame 21, as shown in FIG. A space 33 is provided between the tip and the tip.

Next, to install the screen door 5, hang the upper and lower hanging pieces 28 and 29 on the inner walls 13 and 14 of the upper frame 1 and the lower frame 2 using the "kendon method" of moving the screen door 5 up and down.
The tips of the projecting pieces 26, 26 of the vertical frames 21, 21 are elastically pressed against the indoor side surfaces of the inner walls 15, 15 of the vertical frames 3, 3, and furthermore, ribbed edges 34, 34 are provided on both sides of the screen door 5, and the ribbed edges 34 are pressed. It is pushed between the projecting piece 26 of the screen door 5 and the engaging piece 18 of the window frame F. As mentioned above, since there is a space 33 between the tip of the protruding piece 26 and the ends of the upper and lower frames 19, 20, the pusher edge 34 is pushed in against the elasticity of the protruding piece 26, and the screen door 5 is shifted from side to side. Can be installed in a stable manner.

[How to repurpose the lower window frame] Figure 7 shows the case where the louver window lower frame 2 is repurposed as a component of a multi-stage window. Further, the upper part is a louver window B, and the lower frame 2 is incorporated in the window P between them. That is, the blind P consists of a combination of the lower frame 2 of the louver window B, the core 41 of the approximately T-shaped cross section, and the upper frame 42 of the sliding window A. Due to the necessity of this combination, the lower frame 2 is As shown in FIG. 1, the mounting piece 43 that is nailed to the window sill 8 has been removed.

[Effects of the invention] As explained above, this invention forms projections toward the outdoor side from the stile body on the upper and lower stile and left and right stile of the screen door, respectively, and the projecting frame consisting of the upper and lower projections and the left and right projections The insect screen is supported on the window frame by extending it toward the indoor side, and the louver blades are configured so that they can pass through the window frame and rotate into the protruding frame. Therefore, the upper and lower frames and the vertical frame of the louver window frame can be used for both a single louver window and a multi-tiered louver window with the same cross-sectional shape. The economical efficiency of extrusion molding of materials can be improved.

When installing the screen door, the projecting pieces of the upper and lower frames are hung on the outdoor side of the inner wall of the window frame, while the projecting pieces of the left and right vertical frames are hung elastically on the indoor side of the inner wall, ensuring stability of installation. Of course, the upper hanging piece is longer than the lower hanging piece, so it can be easily fitted from the indoor side using the "Kendon method", and each protruding piece on the upper and lower stile can be fitted easily. A tight material is fitted to seal the space between the window frame and the window frame, effectively preventing insects from entering.
