Description

[Detailed description of the invention] The present invention is a foldable surface lattice in which a plurality of standers are pivotably connected to each other across the upper and lower beams, and the upper and lower frames and a pair of vertical frames are square-shaped. This relates to a structure that is attached to the front of a window frame.

As a mounting structure for this type of surface grid, one is known in which the lower lattice is connected to the lower frame with screws, and the upper lattice is connected to the upper frame with screws.

However, with this structure, the screw holes formed in the upper frame must be aligned with the screw holes formed in the upper frame to tighten the screws, and the heavy surface lattice must be swung to tighten the screws. The operation of matching the holes is very troublesome and troublesome, and the work of attaching the surface grid is troublesome and takes a long time.

The present invention was developed in view of the above circumstances, and its purpose is to provide a surface that can be fixed by clamping the upper frame between the upper frame and the fixing member, making it possible to install the surface grid easily and in a short time. The present invention is to provide a grid mounting structure.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of the surface lattice A, which is pivotally connected to a plurality of stands 3 over the upper and lower decks 1 and 2 by connecting members 4 such as rivets, as shown in FIG. The structure is such that the stand 3 can be folded in an inclined manner around each rivet 4.

Fig. 3 is a vertical cross-sectional view of the grid A installed on the window frame B, and Fig. 4 is a cross-sectional view of the same state. , 7 are framed in a rectangular shape.

The upper frame 5 is attached to the frame C, and its outdoor side is opened downward by an outdoor side wall 5a in contact with the upright inner surface 3a and a vertical wall 5'b of a bent wall 5b bent in a stepwise manner. A groove 8 is formed extending in the longitudinal direction.

The lower frame 6 is attached to the frame C, and on the outdoor side thereof, an upward step portion 6a and a mounting vertical wall 6b located below the upward step portion 6a and on the outdoor side extend in the longitudinal direction. It is formed.

The vertical frame 7 is attached to the frame C, and an outwardly bent bent piece 7a is integrally formed on the outdoor side of the vertical frame 7, and the bent piece 7a is connected to the vertical wall 5'b and the mounting vertical wall 6b. It is located further inside the room so as not to interfere with the upper deck 1 and the lower deck 2.

The upper step 1 includes a mounting piece 1a that is attached to the inner surface of the stand 3a with a rivet 4, and a bent piece 1b that fits into the groove 8 that is continuous and integrally formed on the upper part of the mounting piece 1a, Attach the bent piece 1b to the upper frame 5 with screws 9.
The upper leg 1 is connected to the upper frame 5 by being clamped and fixed in the groove 8 by a fixing member 10 which is tightened by the fixing member 10 .

The lower step 2 has a mounting piece 2a attached to the inner surface 3a of the stand with rivets 4, a horizontal piece 2b that abuts the downward step 6a, and a mounting vertical wall 6b that hangs down from the middle part of the horizontal piece 2b. The lower frame 2 is connected to the lower frame 6 by tightening and fixing the vertical piece 2c to the mounting vertical wall 6b with screws 11.

The distance between the mounting piece 2a and the vertical piece 2c is as follows:
It becomes impossible to insert a screwdriver or the like to tighten the screws 11, and the holes 12 for screwing the screws in the mounting piece 2a, which match the screws 11, are blocked by the standers 3 when the surface grid A is in the installation state shown in FIG. Moreover, when the surface lattice A is folded as shown in FIG. 2, it is formed to open to the outside.

Therefore, in order to attach the grid A to the window frame B,
First, as shown in FIG.
a, and the vertical piece 2c is brought into contact with the mounting vertical wall 6b, and the downwardly opened screw hole 13 of the vertical piece 2c is locked with the screw 11 loosely screwed into the mounting vertical wall 6b, and then a screwdriver is inserted through the hole 12. Then, screw 11 and tighten to connect the lower sill 2 to the lower frame 6.

At this time, since the stand 3 is inclined as shown by the imaginary line in FIG. 5, the hole 12 formed in the lower sill mounting piece 2a opens to the outside, and a screwdriver is inserted into the hole 12 from the outside to screw the screw 11. It is easy to operate.

Then, the surface grating A is swung upward, and the bent piece 1b of the upper arm 1 is fitted into the groove 8 of the upper frame 5, as shown in FIG. Temporarily fix. That is, the vertical piece 1'b of the bent piece 1b is brought into contact with the inner surface of the outdoor side wall 5a, the horizontal piece 1''b of the bent piece 1b is brought into contact with the vertical wall 5'b of the bent wall 5b, The upper deck 1 is temporarily fixed to the upper frame 5 by sandwiching the outdoor side wall 5a between the inner surface of the stand 3a and the vertical piece 1'b.

Then, the screws 15 are screwed into the stand 3 through the screw holes 14 of the mounting piece 1a of the upper deck 1, so that the surface lattice A is fixed in the installed state shown in FIG. 1 so as not to be able to swing.

Next, as shown in FIG. 7, the fixing member 10 is fitted into the groove 8 and fixed with screws 9, thereby connecting the upper leg 1 to the upper frame 1.

That is, the fixing member 10 is a plate-shaped body 10a that is fastened and fixed to the horizontal wall 5''b of the bending wall 5b with screws 9.
The vertical wall 5'b of the bent wall, the vertical bent piece 1'b, and the hook-shaped holding piece 10b that comes into contact with the horizontal bent piece 1''b form a substantially U-shaped cross section, and the hook-shaped holding piece 10
The bent piece 1b of the upper deck 1 is clamped and fixed in the groove 8 of the upper frame by b, thereby connecting the upper deck 1 to the upper frame 5.

Note that the fixing members 10 may be fitted to both sides of the upper deck 1 in the longitudinal direction, respectively.

FIG. 8 shows another embodiment of the upper leg connecting part, in which the fixing member 10 has a substantially U-shaped cross section with a presser piece 10c, and the fixing member 10 is connected to the concave groove 8 with a screw 9.
It is directly tightened to the back wall 8a of the upper frame so that the end vertical piece 1'b of the upper frame bent piece 1b is clamped and fixed by the presser piece 10c, and the inner surface 3a of the vertical frame is separated from the upper frame outdoor side wall 5a. .

In this way, when the surface grating A is swung upward, the upper frame 5, the stand 3, and the upper beam 1 will not interfere with each other, and the vertical bent pieces 1'b can be fitted into the grooves 8. It becomes easier.

Furthermore, when the surface grid A is in the state at the time of installation, the hole 12 formed in the mounting piece 2a of the lower sill 2 is covered with the stand 3 and does not open to the outside, so the screw 11 cannot be loosened and operated, which is preferable from the viewpoint of crime prevention. , the screw 11 cannot be visually seen from the outside, resulting in a beautiful appearance.

The present invention is as described above, and the upper frame 1 can be clamped and fixed between the concave groove 8 of the upper frame 5 and the fixing member 10 and connected to the upper frame 5. There is no need to swing the surface grid A, and the work of installing the surface grid is simple and can be done in a short time.

In addition, since the upper crosspiece 1 and the stand 3 are fixed with screws 15 after the surface lattice is installed, the surface lattice cannot be rotated and folded after installation, and the fixing member 10 must be removed from the outdoor side. Even if the upper frame 1 and the upper frame 5 are separated, the surface grid cannot be rotated and folded, and the screws 15 are difficult to loosen and operate from the outdoor side, and the screws 11 for fixing the lower frame 2 cannot be screwed together. When the stand 3 is in an upright state, that is, when both grids are attached, the holes 12 for opening the grid are blocked by the stand 3 and the screws 11 cannot be loosened, which is preferable in terms of crime prevention since the face grid cannot be removed from the outside.

In other words, since the upper rung 1 and the lower rung 2 are rotatably connected to the stand 3, if the upper rung 1 and the stand 3 are not fixed with the screws 15 after installation, the fixing member 10 can be removed and the stand This is undesirable from a security perspective because it is possible to enter the interior of the room by folding the grid and folding it into an inclined position.

Further, when the surface grid is removed for storage or transportation, it is convenient because the screws 15 can be loosened and folded.
