Description

[Detailed Description of the Invention] The present invention relates to a surface lattice that is attached to a four-sided frame such as a window frame so as to cover the opening thereof.

As a surface lattice, one in which a plurality of stands are connected across the upper and lower rails is known.

On the other hand, as the opening width of the four-sided frame increases, the grid also becomes larger and heavier, and the vertical and horizontal dimensions also become longer, making shipping and transportation of the grid cumbersome.

Therefore, it is conceivable to divide the grid into multiple parts and transport them and install them one after another at the construction site. However, if this is done, gaps etc. will be created in the joints between the grids, and the joints (i.e. , seams) can be visually observed, resulting in poor appearance.

The present invention was developed in view of the above circumstances, and its purpose is to provide a surface lattice that can be divided into a plurality of parts during transportation and whose connecting parts cannot be seen from the outside when assembled.

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

FIG. 1 is a front view of the divided surface lattice seen from the outside, in which a plurality of standers 3 are pivotally connected by connecting members 4° 4 such as rivets across the left upper crosspiece IL and the left lower crosspiece 2L. to form the left side lattice AL.

A right side lattice reduction is formed by pivotally connecting a plurality of standers 3 with rivets 4.4 over the right upper crosspiece IR and the right lower crosspiece 2R.

Note that the left and right side lattices AL, AR can be folded by swinging each stand around each rivet 4.

Right end surface 4 of the upper crosspiece IL and lower crosspiece 2L of the left side lattice AL
The 0 opening is positioned closer to the right side than the rivet 4 on the indoor wall 3'a of the stand 3' located on the membrane layer side, and is located on the right end surface 40.
There is an indoor wall 3 between the opening and the right side wall 3'b of the stand 3'.
A part of 'a (that is, a length range of Sl) is exposed.

The left end surfaces C and 2 of the upper crosspiece IR and lower crosspiece 2R of the right side lattice AL protrude to the left side of the left side wall 3''a of the stand 3'' located on the leftmost side, and the protruding portions 1'R, The length 1 of 2'R is longer than the length S□ than the distance l□ between the predetermined stands.
It's only longer.

Since it is like this, the left side lattice AL and the right side lattice AR
When these are connected and attached to the four-sided frame as shown in Fig. 2, the left upper crosspiece IL and the right upper crosspiece 1R are joined and connected on the back side of the indoor side wall 3'a of the stand 3', and the left side lower crosspiece 2L and The right lower crosspiece 2R is connected to the back side of the indoor side wall 3'a of the stand 3'.

Therefore, the connecting portion between the left and right upper crosspieces IL and IR (that is,
The connecting portion (that is, the joint) between the left and right lower crosspieces 2L and 2R is covered with the stand 3' and is not visible from the outside, which is preferable in terms of appearance.

Next, an embodiment in which the surface grid A is attached to the four-sided frame body B will be described with reference to FIGS. 5 and 6.

FIG. 5 is a vertical cross-sectional view of a state in which the surface grid A is attached to the front part of the four-sided frame assembly B, and the upper frame 5 of the four-sided frame assembly B is attached to the main frame C.
The extension part 5' is attached to and extends toward the outdoor side, and the outdoor side 5'a of the extension part 5' is bent downward to form a mounting piece 6.

The lower frame 7 is attached to the frame C and has an extension 7' extending toward the outdoor side.
A lower crosspiece mounting piece 8 is formed at the upper part of the outdoor side of the extension part 7', and a receiving piece 9 is formed at the lower part of the outdoor side.

FIG. 6 is a cross-sectional view showing the state in which the grid is attached, in which the formwork 10 of the four-sided frame assembly B is attached to the frame C, and an extension 10' is integrally formed toward the outside of the room.

The above-mentioned case 1 has a shape in which bent pieces 1b and 1b are formed on the upper and lower sides of a vertical piece 1a which is pivotally attached to the side surface 3a of the interior of the standing room with a rivet 4, and the bent pieces 1b and 1b are formed on the upper and lower sides of the vertical piece 1a.
An upward fitting groove 11 and a downward fitting groove 12 are formed between the two.

Reference numeral 13 designates an integral upper cover that is fitted and attached between the upper ends of each stand 3, and has an inner wall 13b facing the outside of the stand interior 3a, 3c on both sides of an upper wall 13a that contacts the upper end surface 3b of the stand.
- The outer wall 13c is integrally formed and has a substantially downward U-shaped cross section, and the locking pieces 14 and 15 that fit into the upward and downward fitting grooves 11 and 12 are integrally formed.

The upper cover unit 13 and the upper frame extension 5' are connected by screwing screws 16, which serve as fixing members, across the inner wall slope 13'b and the mounting piece slope 6'.

Reference numeral 17 denotes a swing regulating screw screwed between the stand 3 and the inner wall 13b of the upper cover unit 13.

On the other hand, the lower crosspiece 2 has a shape in which bent pieces 2b are formed on the upper and lower sides of a vertical piece 2a which is pivotally attached to the outside side surface 3a of the stand room with rivets 4, and the upper and lower bent pieces 2b are formed on the upper and lower sides of the vertical piece 2a.
An upward fitting groove 18 and a downward fitting groove 19 are formed between b and 2b.

Reference numeral 20 designates a lower cover that is fitted and attached between the lower ends of each stand 3, and is placed on the stand mounting wall 20a1 that abuts the lower end surface 3d of the stand, the rising wall 20b1, and the lower crosspiece mounting piece 8. It has a substantially crank-shaped cross section with a horizontal wall 20c, and locking pieces 21 and 22 that fit into the upward and downward fitting grooves 18 and 19 are integrally formed.

The lower cover integral 20 and the lower frame extension 7' are connected to the side wall 2.
0c is placed in contact with the lower crosspiece mounting piece 8, and the screws 23 serving as fixing members are screwed and tightened to connect.

Reference numeral 24 denotes a swing regulating screw screwed together between the stand 3 and the rising wall 2°b of the lower cover unit 20.

Therefore, in order to install the surface grid A, first, the upper and lower covers 13 and 20 are placed between the upper and lower parts of each stand 3, and the locking pieces 14, 15, 21, and 22 are aligned upwardly and downwardly. Slide and install from the longitudinal direction so as to fit into the fitting grooves 11, 12, 18, and 19, respectively.

As a result, the surface grid A is regulated by the upper cover integrated 13 and the lower cover integrated 20, and the installation in which the upper and lower crosspieces 1 and 2 and the stand 3 are at right angles is temporarily fixed, and the upper and lower covers integrated 13 and 20 are fixed temporarily. It will not swing unless you slide it in the longitudinal direction.

Then, the screws 17 and 24 are screwed together across the upper and lower covers 13 and 20 and the stand 3 to securely and firmly fix the surface lattice A in the above-mentioned installed state.

In this state, the horizontal wall 20c of the lower cover unit 20 is placed on the lower crosspiece mounting piece 8 and tightened with screws 23, and the inner wall 13b of the upper cover unit 13 is brought into contact with the mounting piece 6 and screwed. At step 16, the tightening is fixed and the surface grid A is attached to the upper and lower frame extensions 5' and 7' of the four-sided frame body B.

As described above, since the foldable surface grid A is temporarily fixed with the upper and lower covers 13 and 20 together so that it does not swing, the installation work can be carried out without the surface grid A swinging during installation. It becomes easier.

Note that the upper Azusa extension part 5' and the lower frame extension part 7' are shorter than the other extension parts 10' and 10' by about the width of the upper cover integral 13 and lower cover integral 20 in the indoor and outdoor directions, making it easier to install the surface lattice. This is easier, and both ends of the upper cover 13, lower cover 20, and upper and lower crosspieces 1 and 2 in the longitudinal direction are covered with a pair of left and right formwork extensions 10' and 10', which is preferable in terms of appearance.

Also, the screw 12 is now to be screwed together from the indoor side,
It is difficult to loosen and operate from the outside, which is good for crime prevention.

The present invention is as described above, and since the grid is divided into a plurality of parts, it is compact during transportation and can be assembled quickly and easily installed during construction.

Further, since the upper rail 1 and the lower rail 2 are divided at the part of the stand 3, the connecting portion is covered with the stand 3 and cannot be visually seen from the outside, which is preferable in terms of appearance.
