Description

[Detailed description of the invention] [Industrial application field] The invention is a device that can be installed on the outside of windows, transoms, etc. (hereinafter simply referred to as windows) that are provided facing the outside of buildings for crime prevention. This invention relates to a mounting structure for a surface grid.

[Conventional technology]

A panel lattice is installed for security purposes, and in order to make it difficult to remove from the outside, it is attached to the frame that supports the window frame from the indoor side with nails or screws, and then the window frame is attached to the frame and nails or screws are used to secure the panel lattice. It is attached to hide the head of.

[The problem that the idea aims to solve]

If the panel grid with the conventional mounting structure is damaged, the window glass must be removed before removing the fixing nails or screws, which takes time.

From this point of view, in prefabricated houses, it is conceivable that the panel lattices may be installed at the construction site to avoid damage to the building panels, which are the building components, during the transportation process, but in that case, the window glass and window frames may also be installed. This will have to be done on-site, and once the grid has been installed, it will not be possible to install the window glass or frame from outside, so you will have to go indoors to do the work.

If you want to install a new grid on an existing house, you must first remove the existing window glass and window frame, install the grid, and then reinstall the window glass and window frame. It won't happen.

As described above, according to the prior art, the work of installing window glass and window frames must be done after the work of installing grids, and in a limited area such as on the indoor side.
To replace the grid, the window glass and window frame must also be removed, making the work complicated and inefficient.

[Purpose of invention]

Therefore, the present invention aims to simplify the work of installing and replacing the grid without impairing its original function of crime prevention.

[Structure of the idea]

That is, the screen grid according to the present invention, as shown in the figure, includes a window frame portion 1 attached to the outdoor side of the glass 11, a screen grid mounting bracket 2, a screen grid 3, a screw cover 4, and a bracket 2 on the window frame 1. Screw 2 to attach
5 and screws 33 for attaching the surface grid 3 to the bracket 2, and the bracket 2 for mounting the surface grid
The grid contacting part 21 and the window frame contacting part 22 are configured in a shape that is perpendicular to each other, and when the window frame contacting part 22 is attached to the inner surface of the window frame 1 with screws 25, there is a gap between them. A gap 27 opened toward the outside is formed, and jagged irregularities 26 are provided on the surface of the window frame abutting portion 22 facing the window frame 1 in the gap 27, and the surface lattice 3 is attached to the window frame 1. It is attached with screws 33 in contact with the surface grid abutting portion 21 of the bracket 2, and when the screws 33 are inserted into the places on the outer surface of the surface grid 3, the screws 33 are inserted. Plate 3 to the extent that the head is buried.
The screw cover 4 is configured so that the screw covering part 41 and the insertion part 42 are perpendicular to each other, the insertion part 42 is shaped to fit into the gap 27, and the jagged unevenness is formed. A jagged unevenness 43 is formed on the surface facing 26 so that the jagged unevenness 26 and 43 closely engage with each other, and the screw covering part 41 is inserted into the gap 27 so that the insertion part 42 is inserted into the gap 27. In the fitted state, the screws 33 fit into the fitting locations of the surface grid 3 recessed from the outer surface, and the inner surface of the screw covering portion 41 facing the screws 33 is located on the indoor side from the outer surface of the surface grid 3. into a shape that covers the head of the screw 25.
The present invention is characterized in that the head of the screw 25 is installed at a position where the head of the screw 25 is covered by the side surface 32 of the periphery 31 of the surface grid when the surface grid 3 is attached in contact with the surface grid abutting portion 21.

In this way, the bracket 2, the surface grid 3, and the screw cover 4 in the present invention are constructed with the above-mentioned relationship. 2 to the window frame 1, then attach the screen grid 3 to the screen grid abutment part 21 of the bracket 2 with screws 33, then press fit the insertion part 42 into the gap 27 and attach the screw cover 4, The screw covering portion 41 covers the head of the screw 33 to attach the surface grid.

To explain more specifically, in the figure, 7 is an architectural panel of the entrance unit made of aluminum sash, which is installed on the wall 6, and the window glass 11 is attached to the glass window frame 1 in parallel with the entrance door 5. ing.

Screen grid contacting part 21 of the screen grid mounting bracket 2
The window frame abutting part 22 and the window frame abutting part 22 are orthogonal to each other in an L shape, and the window frame abutting part 22 and the holding part 23 are continuous approximately in parallel. It is fixed by coming into contact with it through.

There is a step 24 between the contact part 22 and the clamping part 23, and a gap 27 is created between the clamping part 23 and the inner surface 12 in the abutting and fixed state.
5 falls into and hides in the abutting part 22 recessed from the clamping part, and therefore, the face grid 3 is fitted between the left and right clamping parts 23 and 23' without being obstructed by the head of the screw, and is screwed in by the screw 33. It is attached to the contact part 21.

The screw cover 4 has an insertion part 42 and a screw covering part 41.
are perpendicular to the L-shape, and after installing the bracket 2 and the face grid 3, apply a piece of wood or the like to the screw covering part 41 and insert the insertion part 42 into the gap 27 between the inner surface 12 and the clamping part 23. Driven into it.

[Effect of idea]

As described above, in the present invention, (1) the bracket 2 and the face grid 3 are sequentially attached from the outside of the window frame 1 to which the glass 11 is attached, and finally the head of the screw 33 that fixes the face grid 3 with the screw cover 4 is attached. There is no need to remove the glass 11 in order to attach the surface grid 3.

(2) Therefore, glass 1 is used in the construction panels of prefabricated houses.
1 is attached first and transported, and only the surface grid is attached at the construction site, thereby avoiding damage during the transportation process.

(3) Also, since the grid can be installed after installing the window glass and window frame, it is possible to install the window glass and window frame from both the indoor and outdoor sides, and there is no need to go back and forth to the indoor side to install them. The installation work can be done efficiently without any problems, and the installation of the grid on existing houses can be done easily.

(4) After installation, tighten the mounting screw 2 of bracket 2.
5 is hidden in the side wall 32 of the surface lattice 3, and the surface lattice 3
The mounting screws 33 are hidden under the screw cover 4, and the screw cover 4 is integrated with the bracket 2, so the mounting structure of the surface grid 3 is difficult to distinguish from the outside, and the screw cover 4 installed at the end is also hidden. Since it is firmly held between the window frame 1 and the bracket 2, there will be no problem in terms of crime prevention.

(5) In particular, the contact surfaces of the clamping part 23 of the bracket and the insertion part 42 of the screw cover have serrations (unevenness) 26 and 43, respectively, and since they engage, the screw cover 4 is more firmly integrated with the window frame 1. be held in place.
