Description

[Detailed description of the invention] This invention relates to a structure in which a surface lattice consisting of an upper crosspiece, a lower crosspiece, and a plurality of standers is attached to the front surface of a four-sided frame framed in a rectangular shape by an upper and lower frame and a pair of vertical frames. be.

Conventionally, this type of surface lattice mounting structure includes a foldable surface lattice in which a plurality of standers are pivotally connected to the upper and lower beams so as to be swingable, and a top and bottom frame and a pair of vertical frames are used. It is known that the lower end face of each stand of a grid is attached to a four-sided frame formed in a rectangular shape by positioning it in contact with the lower frame of the four-sided frame.

However, since the face lattice is formed by cutting a long profile material to a predetermined size, the lower end surface becomes a cut surface and becomes irregular, and it is difficult to pivotally connect multiple standers to the upper and lower crosspieces. In this case, it is difficult to align the lower end surfaces of each stand at the same horizontal position.

For this reason, if the bottom end surface of the stand is positioned in contact with the bottom frame as described above and installed, the uneven bottom end surface becomes the reference surface, making it difficult to install, and also making it difficult to install while maintaining a horizontal state. It has a defect.

In addition, the part of the lower frame of the four-sided frame that the lower end surface of the stand comes into contact with is horizontal so that the grid can be installed while keeping it horizontal.
Sand, dust, rainwater, etc. tend to accumulate in this area, which is undesirable.

The present invention was developed in view of the above circumstances, and its purpose is to mount the lower crosspiece as a reference surface, to make the installation work easier, and to maintain the horizontal position when installing.
Furthermore, it is an object of the present invention to provide a surface lattice mounting structure that prevents sand, dust, rainwater, etc. from accumulating in the lower frame portion that supports the lower end face of the stand.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

Fig. 1 is a perspective view of a state in which a surface lattice is attached.Inside the four-sided frame assembly A, which is a window frame made by framing an upper frame 1, a lower frame 2, and a pair of vertical frames 3, 3 in a rectangular shape, there are multiple A shoji door B is housed therein, and a surface lattice C is attached to the outdoor side of the four-sided frame body A.

The surface lattice C has a plurality of standers 6 arranged between an upper crosspiece 4 and a lower crosspiece 5, both ends of which are rotatably connected by connecting members 7, 7 such as rivets, and each connecting member It can be folded around 7.

The upper frame 1 is attached to the frame D, and has an extension 1' integrally formed on its outdoor side, and a downwardly bent piece 1'a is integrally formed on the outdoor side of the extension 1'. A mounting piece 8 is formed.

The lower frame 2 is attached to the frame D, and an extension part 2' is integrally formed on the outdoor side of the lower frame 2. The upper position of the extension part 2' on the outdoor side becomes the lower frame mounting part 9, and the intermediate position is an extension part 2'. A vertical frame lower cover piece 10, which has a crank-shaped bent piece 2'a integrally formed thereon and forms a slope that slopes downward toward the outdoor side, is formed below the lower crosspiece mounting portion 9 and on the outdoor side. There is.

The vertical frame 3 is attached to the frame D, and an extension 3' is integrally formed on the outdoor side thereof.

The upper crosspiece 4 includes an inner piece 4a pivotally connected to the indoor side surface 6a of the stand 6 with a rivet 7, an upper piece 4b covering the upper end surface 6b of the stand 6, and an outdoor side surface 6c of the stand 6.
and the opposing outer piece 4c form a substantially downward U-shape. 4'a, screws 11 serving as fixing members are screwed together to connect and fix the upper crosspiece 4 and the extension part 1' of the upper frame 1.

The lower crosspiece 5 has rivets 7 on the side surface 6b of the standing room.
The vertical piece 5a is pivotally connected to the lower crosspiece mounting portion 9.
The horizontal piece 5b placed above forms a hook-shaped bent shape, and the horizontal piece 5b and the lower crosspiece mounting portion 9 are connected and fixed by tightening screws 12 serving as fixing members.

Therefore, in order to attach the surface lattice C to the four-sided frame assembly A, first, a plurality of standers 6 are pivotally connected with the rivets 7 across the upper and lower members 4 and 5 to form the surface lattice C. Place the horizontal piece 5b of No. 5 on the lower frame mounting part 9 of the lower frame extension part 8' to position it in the vertical direction, and connect and fix the horizontal piece 5b and the lower frame mounting part 9 by tightening the screws 12. do.

Then, the inner piece 4a of the upper frame 4 and the upper frame extension part 1'
At the same time, the swinging of the stand 6 is regulated by tightening and connecting the mounting piece 8 with the screw 11.

As described above, since the horizontal piece 5b of the lower frame 5 is placed on the lower frame mounting portion 9 of the lower frame extension 2' for vertical positioning, the lower end surfaces 6d of each stand 6 may be uneven. In addition to being able to be installed horizontally even when
When screwing together the screws 12, the surface grid C can be stably supported on the lower crosspiece mounting portion 9 via the lower crosspiece 5, which facilitates the screwing operation of the screws 12, making the installation work easier. Installation is also secure.

Further, since the stand lower cover 10 located below the stand lower end face 6d has a slope that slopes downward toward the outdoor side, rainwater etc. are difficult to accumulate on the stand lower cover 10, which is preferable.

Furthermore, the screws 12 are screwed together from the indoor side, making it difficult to unscrew them from the outdoor side, which is favorable for crime prevention.

Furthermore, since the upper frame extension 1' is shorter than the other extensions 2' and 3', the surface grid can be easily attached.

The present invention is as described above, and since the horizontal piece 5b of the lower crosspiece 5 is placed on the lower crosspiece mounting portion 9 and fixed with the screws 12, the horizontal piece 5b of the lower crosspiece 5 is used as a reference plane in the vertical direction. Can be positioned and installed, lower end surface 6d of each stand 6
Even if the screws 12 are not aligned, it can be installed while maintaining a horizontal state, and when the screws 12 are screwed together, the surface grid C can be stably placed and supported on the lower crosspiece mounting portion 9 via the lower crosspiece 5. This makes the screwing work easier, making the installation work easier and the installation more reliable.

The upper part of each stand 6 is fitted into the upper crosspiece 4, and the lower end surface 6d is located above the cover piece 10 for the lower part of the stand, so that the cut and unsightly upper and lower end surfaces of each stand 6 are not visible from the outside. looks better.

In addition, since the cover piece 10 for the lower part of the stand is inclined downward toward the outdoor side and is located below the lower crosspiece mounting part 9, rainwater etc. can be drained smoothly, and the bottom of each stand 6 is lowered. It can be installed even if the position of the end face 6d is slightly uneven.

In addition, the upper part of each stand 6 is a substantially downward U-shaped upper crosspiece 4.
and insert the inner piece 4a of the upper frame 4 into the upper frame 1.
Since it is fixed to the protruding end of the extension part 1' with a screw 11, there is no need to form a recess in the upper frame 1 into which the upper part of the stand 6 is fitted, and the shape of the upper frame 1 can be simplified.
