Net screen

Abstract

To solve the problem in which: in the case of net screens attached to frames for sliding windows, when grids or louvers for preventing intruders from entering or protecting against rain are fixed to the net screens, it becomes difficult to replace the nets and impossible to move windows or shutters; and in addition, when attaching the net screens covering the entire frame from the indoor side to make it impossible to move the net screens themselves, it is difficult because there is nothing to hold onto.SOLUTION: By fitting grids and louvers inside a net screen frame and fixing them on the opposite side of the net, it becomes possible to replace the net and prevent the grids and the louvers from coming into contact with windows or shutters. In addition, by covering the entire window frame with the net screen itself, the net screen becomes immovable, preventing intruders from entering. Furthermore, by having a handle to be held around the center of the entire net screen, it becomes possible to install the same from the indoor side by holding the handle, thereby resolving the problem.SELECTED DRAWING: Figure 6

Description

[Technical field]

[0001] The present invention relates to a technology relating to a screen door that is attached to a frame for a sliding window frame installed in a building such as a house or a store. [Background technology]

[0002] This invention relates to a screen door that is attached to the frame of a sliding window installed in a building and that has an intrusion prevention grille or rain protection louvers attached to it in order to provide protection from rain and the ability to prevent intruders from entering. [Prior art documents] [Non-patent literature]

[0003] Real whole Showa 53-095550 Summary of the Invention [Problem to be solved by the invention]

[0004] When lattices or louvers are fixed to the top, bottom, left and right bars of a screen door, the screen is stretched inside the bars, so the lattices and louvers get in the way and make it difficult to replace the screen.

[0005] When bars or louvers were attached to a screen door, there was a problem that they would interfere with each other because the distance between the screen door and the window or the shutter is close.

[0006] Furthermore, with single-sided screen doors fitted with bars or louvers that are attached to conventional sliding window frames, only one side of the window frame can be used. In addition, single-sided screen doors with bars attached could not prevent intruders from entering from outside when the screen was in use, because the screen itself could easily be moved from side to side.

[0007] When installing a full screen screen that can completely cover the frame of a sliding window from inside the house, it is necessary to leave a gap between the full screen screen and the window frame so that the user can fit their hands in, and the width of the full screen screen must be reduced to accommodate this gap. This resulted in large gaps on both sides when the full screen screen was installed. Furthermore, since the window got in the way when installing the screen, it was necessary to hold the center of the screen screen. Furthermore, if the full screen screen was wide, it was difficult for one person to hold the bars on both ends. [Means for solving the problem]

[0008] Fix the lattice or louvers to the battens on the opposite side to where the netting is stretched.

[0009] To ensure that the louvers fit within the thickness of the battens as much as possible, they are fixed so that most of the louvers fit inside the battens.

[0010] A single-sided screen for sliding windows with fixed bars or louvers is converted into a full screen that can cover the entire window frame and is fixed to the window frame so that it cannot be easily removed. There is no particular method of fixing. A full screen may be divided into two parts to make installation easier.

[0011] In order to enable the full screen door to be installed from inside, handles are provided on the inside side of the screen, which are fixed to the top, bottom, left and right rails and pass through the center of the screen door. The number of handles and their angles (horizontal, vertical, etc.) can be left unspecified, and they can be removed after installation. Also, since the handles are for holding the item, they do not have to be plate-shaped, and can be made of wire or other materials. Furthermore, the attached lattice or louvers can have the same function as the handles. Effect of the Invention

[0012] The present invention is expected to provide the following effects.

[0013] By fixing the lattice or louvers to the battens on the opposite side to where the net is stretched, it is possible to replace the net as before without removing the lattice or louvers.

[0014] Because the louvers fit within the thickness of the bars, they do not interfere with windows or shutters, and they can be installed on sliding windows or window frames with shutters.

[0015] By installing a full screen that covers the entire window frame, it becomes possible to open both sides of the window and let air in through the screen from both ends. Also, since a fixed full screen cannot be moved, it prevents intruders from getting in.

[0016] The handle that can hold the center of the screen on the indoor side of the screen makes it possible to install the screen from inside the house while holding the handle. This allows the width of the screen to be closer to the width of the window frame. [Brief description of the drawings]

[0018] The screen door according to the present invention will be described in detail below with reference to the drawings.

[0019] As shown in Figure 4, 5. a full-screen screen that can cover the entire window frame in which the louvers will be installed and the sliding window will be installed is attached to 6. the window frame. 3. In order to increase the strength of the lattice and the rain protection effect of the louvers, and to ensure that they do not interfere with the screen when the shutter or window is moved, 1. Fix the lattice and louvers so that they fit inside the sash. 2. In order to allow the screen of a screen door to be replaced in the same way as before, the grille or louvers installed as shown in Figures 1 and 2 should be fixed to the side opposite the screen. In order to allow the screen to be installed from the indoor side without holding the outer frame of the full screen, a handle is attached that allows the center of the full screen to be held, as shown in Figure 6.
