Description

[Detailed Description of the Invention] The present invention relates to a surface lattice with an insect-proof net that can be attached to the entire window of a bathroom, kitchen, toilet, etc. for both crime prevention and decoration purposes.

Conventionally, a screen door is attached to the screen storage area of a sash window frame, and a screen lattice is attached to the outside of the screen door at an appropriate interval using brackets or the like to the sash window frame edge or a building wall around the sash window frame.

However, with such a screen door installation structure.

When installing a shoji door, it is necessary to leave a wide gap between the screen door and the screen lattice in order to be able to remove it, and installing the screen lattice is troublesome, and moreover, the installation can cause damage to the building walls, etc. What problems did I have?

Therefore, in recent years, various types of screen lattices with insect-proof nets have been proposed, such as the following, which integrate a screen door and a screen lattice.

1) A type of lattice that is mounted on the window frame rail, with an insect repellent screen stretched on the indoor side of the screen door frame, and a lattice built into the inside of the screen (Utility Model Application Publication No. 53-40653) ).

2) When installing a shoji on the outdoor side opening of the window frame body, a lattice mounting frame is specially prepared with wide intervals so that it can be removed, and the shoji is housed within the frame and fixed with the left and right lattices. A surface lattice in which a plurality of lattices including left and right lattices are connected by upper and lower horizontal bars (Japanese Unexamined Patent Publication No. 52-80632).

However, while the above method 1) has the advantage of being easy to install and not damaging building walls, etc., the screen door frame has a small expected width and is weak, and the lattice installed inside the screen door frame is also weak. Therefore, it is difficult to obtain sufficient strength as a planar lattice.

In addition, with the method 2), although it is possible to design a surface lattice with sufficient strength, it cannot be mounted on a regular sash because it requires a lattice mounting frame.

The present invention was devised to solve the above-mentioned conventional problems, and its purpose is to install a surface lattice regardless of whether it is an existing sash window frame or not, without the need for a special frame.
The object is to provide a surface lattice with an insect-proof screen that can be installed in the screen storage part of a sash window frame, has sufficient strength in the state of construction, and has a good appearance.

Hereinafter, the present invention will be explained with reference to an illustrative embodiment.This screen grid consists of a rectangular frame body 3 having left and right car frames 1, 1 and upper and lower horizontal frames 2, 2, and an insect screen 4 stretched on the interior side surface of the rectangular frame body 3. A lattice 5 made of hollow extruded material is attached to the outside side of the vehicle frame 1 in parallel with the vehicle frame 1, and a lattice 5 is also attached to the outside side of the vehicle frame 1 of the rectangular frame body 3.
A reinforcing strip 6 of the same shape and size is integrally provided.

The indoor side surface of this grid is of a size that can be fitted into the left-right opening of the screen door storage section on the outdoor side of the sash window frame 13.

The vehicle frame 1 has a rectangular frame body 30 with a groove-shaped cross section opening toward the indoor side, and is provided with a rope attachment groove 7 on the inner side in the direction opposite to the vehicle frame, which matches or retreats from the position of the inner surface of the web 1a.

Further, on the outer sides of the left and right vehicle frames 1, 1 in the direction in which the vehicle frames face each other, a protrusion portion 17 is provided integrally with the vehicle frame 1, and the protrusion portion 17 is formed so that its tip portion abuts against the outdoor side surface of the sash window frame 13.

In addition, the horizontal frame 2 has a mounting groove 8 that opens outward in the direction opposite to the horizontal frame, and a screw insertion groove 9 and a rope attachment groove T on the lip groove-shaped surface opening toward the indoor side of the rectangular frame 3 on the inside in the direction opposite the horizontal frame. It is equipped with

The rectangular frame body 3 connects the end of one flange of the vehicle frame 1 to the rope attachment groove 7.
The end surface 2b of the horizontal frame 2 is cut through the removed portion.
It is assembled by connecting the horizontal frame 2 to the vehicle frame 1 with screws 10 in the screw insertion groove 9, with the exterior side surface 2a facing the inner surface 1b of the other flange, and the outside side surface 2a facing the inner surface 1a of the web.

The end portion of the lattice 5 is connected to the horizontal frame 2 with screws 10 in the screw insertion grooves 9 of the rectangular frame 3.

The casing and reinforcing strips 6 are attached to this grid 5 together with the web of the car frame 1.
It has the same shape and size as.

However, the reinforcing strip 6 may be attached to the outer surface of the web as a separate body from the vehicle frame 1, and fixed by screws or the like.

In addition, if the reinforcing strips 6 have the same shape and size as the grid 5, they will look good together with the grid 5, but if the car frame 1 can be reinforced at least, the reinforcing strips 6 should have the same shape and the same size as the grid 5. Furthermore, it does not have to have a hollow cross section.

The rectangular frame 3 further has rope attachment grooves 7, 7' in which the ends of the protrusions 11 on the inner surface in the direction opposite to the horizontal frame, which constitute the rope attachment groove 7' of the horizontal frame 2, are cut off to make the inside continuous.

7. Equipped with T.

The insect net 4 has a holding rope 1 in this continuous rope attachment groove.
2, the frame is stretched over the indoor side surface of the rectangular frame 3.

This surface lattice is installed in the outdoor side part of the sash window frame 13 in a building manner by fitting the upper and lower screen door rails 14 of the sash window frame 13 into the mounting grooves 8 of the upper and lower horizontal frames 2.

At this time, as shown in FIG. 2, both the left and right sash window frames 13.
The indoor side of the rectangular frame 30 (the indoor side of the rectangular frame body 30) is fitted between the inner side ends 13a of the openings 13, 13a.

In addition, a protrusion 17 integrally provided on the outdoor side surfaces of the left and right sash window frames 13, 13 from the left and right car frames 1, 1 of the rectangular frame body 3.
The tips of the two come into contact with each other.

Then, the steady rest 1 is installed in the mounting groove 8 of the upper and lower horizontal frames 2.
5, and is externally stopped by an external stop 16 attached using the screw insertion groove 9 of the upper horizontal frame 2.

In the above configuration, grids are installed parallel to the left and right car frames at appropriate intervals on the outdoor sides of the upper and lower horizontal bars, and reinforcing strips parallel to the grids are integrally provided on the outdoor sides of the left and right car frames. The rigidity of the rectangular frame of the lattice can be increased in the vertical direction, and the upper and lower horizontal bars are provided with mounting grooves that open outward in the direction opposite to the horizontal frame, and these mounting grooves are connected to the upper and lower sides of the screen storage area of the window frame. Since it is fitted into the screen door rail, the rigidity of the rectangular frame of the screen lattice can be increased in the left and right direction.

In this way, the rigidity of the rectangular frame constituting the screen lattice is increased in both the vertical and left and right directions, making it possible to stabilize the tensioning state of the insect net on the indoor side surface of the screen lattice.

In addition, it can be installed on the left and right vehicle frames without any mounting hardware by simply fitting the rectangular frame of the surface lattice into the upper and lower screen door rails of the screen door storage area of the first trench window frame. The insect-proof screen lattice of the present invention has the advantage that it can be easily installed in the screen storage area of an existing sash window frame.

Furthermore, the insect-proof screen lattice of the present invention has a size that allows the indoor side to be fitted into the left-right opening of the screen storage section of the window frame, and the outdoor side ends of the left and right car frames of the screen lattice on the opposite side of the car frame. Since the ridge is integrally provided with a protrusion whose tip abuts against the outdoor side of the window frame, when the screen lattice is installed in the screen storage area of the window frame, the indoor side of the screen lattice can be placed inside the window frame. become,
It is possible to reduce the protrusion of the lattice and reinforcing strips from the window frame, and also to make the surface lattice fit against the window frame without wobbling. By being in contact with the exterior side of the vehicle, the space between the exterior side edges of the left and right vehicle frames of the grid on the opposite side of the vehicle frame and the exterior side of the window frame is covered by the protrusion, creating a neat and clean structure that prevents insects from entering. It is possible to create an appearance that is not heavy.
