Description

Bar for window of crimes prevention}

The present invention relates to a security window (防 犯 窓), more specifically, for a security window that can be easily fixed to a window frame while having excellent mechanical strength, good ability to suppress intrusion from the outside, and a beautiful appearance. It's about grate.

In general, the walls of various buildings are provided so that windows can be opened and closed for lighting, ventilation, and securing a clock. However, various accidents such as theft frequently occur due to intrusion from the outside through such a window. Of course, the window is provided with a locking device, but because it is made of glass relatively easy to break into the room as well as open the window in the summer, it is very easy to break in, so always careful attention is required.

Therefore, as shown in Figure 1, the so-called security window (Wp) to prevent intrusion from the outside in the window (W) may be installed together with the glass window (Wg), such a security window (Wp) instead of the glass (G) The grate B made of metal is installed on the window frame Fp to effectively block the opening of the window W even when the window Wg for ventilation is opened, for example, to make intrusion from the outside very difficult.

On the other hand, the grate (B) of the security window (Wp) is usually produced in various forms by die casting (die casting) in consideration of both the robustness to prevent intrusion and the aesthetics for the exterior of the house, but the production is difficult and expensive There is a problem.

Accordingly, in recent years, the hollow pipe made of stainless steel or titanium is cut to the required length and fixed to the window frame (Fp) on a stripe or a lattice, thereby easily forming a grate (B). The diameter of (B) is constrained, making it difficult to ensure robustness, and the simple shape of the grate (B) can adversely affect the aesthetics of the building.

In other words, the security window (Wp) is installed in the window frame (F) of the building wall in double with the glass window (Wg), the width of the window frame (F) is standardized to fit the wall thickness of the building bar, the window frame (Fp) Because the width is limited to a certain amount or less, the diameter of the grate (B) is also limited to a certain amount or less.

For example, the diameter of the grate B may be increased by increasing the width of the window frame Fp of the security window Wp, but in this case, the installation itself is difficult due to the lack of compatibility with the security window Wp that should be installed in a standardized window. In addition, there is a problem such as the need to make a new mold for the window frame (Fp) made of aluminum extrusion is not a solution.

2 schematically shows an example of a conventional pipe grate 1 for solving such a problem. It combines the copper pipe 3 having a smaller length to the outer periphery of the stainless steel pipe 2 to form a double pipe form, and the plastic fastening block 4 having the country hole 4a at both ends of the stainless steel pipe 2 is formed. Combining the interference fit method is fixed to the window frame (Fp) with a screw (5).

However, since the conventional pipe grate 1 is fixed to the stainless pipe 2 by pressing both ends of the copper pipe 3 by a rolling process, it is not only difficult to manufacture, but also at both ends of the copper pipe 3. Rolling marks remain to degrade the appearance, especially when a large external force is applied there is a fear that the screw hole 4a of the fastening block 4 made of plastic breaks.

The present invention is designed to solve the above-mentioned conventional problems, the purpose of providing a security window grate that can increase the strength of the pipe-shaped grate and can build a very solid and stable fixed state for the window frame have.
