Description

  The present invention relates to a surface lattice that can switch an opening of a surface lattice body between an open state and a shield state. More specifically, the present invention relates to a surface lattice that is shielded by stretching a screen and opened by winding the screen. The present invention relates to an openable / shieldable surface grid.

From the viewpoint of crime prevention, it is widely practiced to provide a face grid on the window. The surface lattice is open between the lattices, but may be desired to be shielded depending on the situation.
Conventionally, when shielding between face grids, translucent plastic flat plates, corrugated sheets, etc. are attached between the face grids, but they are fixed so that an openable screen can be retrofitted. Has been proposed (Patent Document 1). However, since it is not intended to be attached to a surface grid that was originally designed for screen installation, installation is cumbersome, the screen winding device is bulky, and the workability is poor and the design properties are also low. There were problems such as damage.
In addition, a surface lattice incorporating a screen that can be opened and closed from the beginning has also been proposed (Patent Document 2), but a screen winding device is simply attached to the upper portion of the surface lattice so that the screen can be opened and closed on the surface lattice surface. Therefore, the operability and the design are not sufficiently taken into consideration, and there is no great difference from the above-described surface lattice with the screen attached.

The moving grid 3 is a sliding door mounted in the surface grid outer frame 2 so as to move in a sliding manner, and has an outer moving grid 3A positioned outside as viewed from the building side, and an inner side. The inner moving grid 3B is positioned, and is configured by connecting a grid member composed of several vertical grids 31a to 31c and upper and lower horizontal grids 32 and 33 that connect upper and lower ends thereof. .

Among the moving grids 3, the vertical grids in the inner moving grid 3 </ b> B are provided with a vertical grid 31 a constituting a screen grid 34 described below and a lock mechanism 35 described later, as shown in FIGS. 2 and 3.

On the other hand, the vertical lattices 31a to 31c in the outer moving lattice 3A are all formed by simple vertical lattices in the illustrated example, and upper and lower ends thereof are connected by upper and lower horizontal lattices 32 and 33.

  The screen grid 34 has a form generally known as a roll screen device, and a hollow winding shaft 34a for winding the screen 4 is rotatably supported inside the lattice frame. A spring serving as a drive source for winding the screen 4 is incorporated in 34a. Then, the screen 4 is wound around the winding shaft 34 a by the spring and stored in the screen lattice 34.

The moving grid 3 is attached to the left and right sides of the surface grid outer frame 2 so as to be pulled left and right, and is held as shown in FIGS. 1 to 3.

Therefore, in this state, the opening 5 of the surface lattice body 1 is open, but the screen 4 is pulled out from the screen lattice 34 by moving the movable lattice 3 to the state shown in FIGS. The opening 5 of the surface lattice body 1 is shielded by the screen 4. That is, the screen 4 is interlocked with the movement of the moving grid 3 so as to open or shield the opening 5 with the movement of the moving grid 3.

  The vertical grid 31c of the outer moving grid 3A that overlaps the screen grid 34 with the moving grid 3 held as shown in FIGS. 1 to 3 can also be configured by the screen grid 34. In this case, The tips of the screens 4 in the screen lattices 34 constituting the vertical lattice 31a in the inner moving lattice 3B and the vertical lattice 31c in the outer moving lattice 3A are fixed to each other.

Further, as can be seen from FIGS. 2, 3, 5, and 6, the lock mechanism 35 attached to the central vertical lattice 31b of the inner moving lattice 3B is formed in the vertical lattice 31b by rotating the lock operator 35a.

Openings 35c and 35c are provided at opposing portions, respectively, to which the tips of the rods 35b and 35b are locked.
The rods 35b and 35b and the openings 35c and 35c constituting the lock mechanism 35 are not limited to the positions described above, and can be arranged to face arbitrary lock positions on the outer and inner movable grids 3A and 3B. Further, any known mechanism using a link or a cam can be adopted as a mechanism for vertically moving the rods 35b and 35b in the vertical lattice 31b by rotating the lock operation element 35a.

Next, a description will be given of the configuration of a synchronous movement mechanism that moves the outer and inner moving grids 3A and 3B in a reverse direction in synchronization with each other by connecting them with a connecting member.
As shown in FIGS. 1, 4 and 7, the synchronous movement mechanism in the first embodiment connects the moving grids 3A and 3B with a connecting member composed of flexible wires 40a and 40b. Thus, it is possible to move in the opposite direction in synchronization with each other. Specifically, the same side ends (left ends and right ends) of the two moving gratings 3A and 3B are mutually connected to the wires 40a and 40b. (See FIG. 8), on the other hand, wire wrapping tools 43A and 43B are provided at substantially the center in the upper and lower horizontal frames 22 and 23 constituting the surface lattice frame 2, respectively, and these wire wrapping tools 43A and 43B. Is a diverter (roller) 44a, 44b for turning the wires 40a, 40b connected to the respective end portions of the moving grids 3A, 3B outward, and one turned by the diverter. It includes wire 40a, 40b of the outer and inner moving grating 3A, and a guide wheel 44c for guiding between 3B.

  That is, in FIG. 1, the wire 40a connected to the left end portion of the outer moving grid 3A is wound around the coaxial turner 44a on the other side through the guide wheel 44c from the turner 44a in the wire hook 43A (see FIG. 1). 7), and is connected to the left end of the inner moving grid 3B. The length of the wire 40a is such a length that the two moving gratings 3A and 3B can take the position of FIG. 1 or FIG. The other wire 40b is also opposite to the above, but is similarly stretched between the right ends of the moving grids 3A and 3B.

  FIGS. 8A to 8C schematically show different movement states of the moving grid 3 in another example of the synchronous moving mechanism that can be employed in the surface grid of the first embodiment. The mechanism connects the left and right ends of the two moving grids 3A and 3B with flexible wires 41a and 41b, respectively, as in the case of the above embodiment. Wire wrapping tools 43A and 43B are respectively provided at substantially the center in the upper and lower horizontal frames 22 and 23 constituting the wire 2, and these wire wrapping tools 43A and 43B are connected to the respective ends of the moving grids 3A and 3B. The wires 41a and 41b are configured as turning elements (rollers) 45a and 45b that guide the moving grids 3B and 3A on the opposite sides.

That is, the wire 41a connected to the right end portion of the outer moving lattice 3A is wound around the turning portion 45b via the turning portion 45a in the wire winding tool 43A and connected to the right end portion of the inner moving lattice 3B. The length of the wire 41a is such a length that the two movable gratings 3A and 3B can take the positions of (A) and (C) in FIG. The other wire 41b is also stretched in the same manner although it is opposite to the above.
8A shows a state in which the screen 4 is housed in the screen grid 34 and the openings 5 in both the moving grids 3A and 3B are opened, and FIG. 8B shows two moving grids 3A and 3A. 3B is located at the center, so that the screen 4 is stretched only on the portion where both moving grids are located. FIG. 4C shows the screen 4 stretched across the entire surface and the moving grids 3A and 3B. The state which the opening part 5 was shielded is shown.

FIGS. 9A to 9C schematically show different moving states of the moving grid 3 in another configuration example of the synchronous moving mechanism. The left ends and the right ends of the two moving grids are shown in FIG. Are wound around wire wrapping tools 43 </ b> A and 43 </ b> B provided at both corners of the upper and lower horizontal frames 22 and 23 constituting the outer lattice frame 2.
That is, the wire 42a connected to the right end of the outer moving grid 3A is wound around the turning element 46a in the wire winding tool 43A and then connected to the right end of the inner moving grid 3B. The length of the wire 42a is such a length that the two movable gratings 3A and 3B can take the positions of (A) and (C) in FIG. Further, the other wire 42b is tensioned in the same manner although it is opposite to the above.

With these configurations, the outer moving grid 3A and the inner moving grid 3B can be configured such that when one is moved, the other is moved to the opposite side in synchronization with the other.
Here, in order to facilitate the operation of the surface lattice, the wire and the wire wrapping tool constituting the synchronous movement mechanism are provided in both the upper and lower horizontal frames 22 and 23. 22 and 23 can be provided only on one of them.

Next, the operation of the surface grating of the first embodiment will be described.
As shown in FIGS. 1 to 3, in a state where the outer moving grid 3A is in contact with one vertical frame member 20 of the surface lattice outer frame 2 and the inner moving grid 3B is in contact with the other vertical frame member 21, The screen 4 is accommodated in the screen lattice 34, and the opening 5 of the surface lattice main body 1 is opened. In this state, the rods 35b built in the vertical grid 31b of the inner moving grid 3B can be passed through the respective openings 35c provided in the upper and lower horizontal frame members 22 and 23 so that both the moving grids 3 cannot be moved. .

  Next, when the window to which the face grid is attached is to be blinded, the rod 35b engaged with the opening 35c is removed from the opening 35c by the lock operator 35a, and the outside or The inner moving grids 3A and 3B are moved toward the other vertical frame member. In this case, the outer and inner moving grids 3A and 3B are synchronously moved in opposite directions by the synchronous movement mechanism, and along with this movement, the vertical grid 31a in which the tip of the screen 4 of the outer moving grid 3A is fixed. As a matter of course, the screen 4 is pulled out from the screen grid 34 in combination with the movement of the screen grid 34 of the inner moving grid 3B, and the drawn screen 4 is connected to the vertical grid 31a of the outer moving grid 3A. It is stretched between the screen lattice 34.

Then, the inner moving grid 3B is in contact with the vertical frame member 20 and the outer moving grid 3A is in contact with the vertical frame member 21, that is, the inner moving grid 3B and the outer moving grid 3A are opposite to the state described above. In the state of the pulling position, the screen 4 is stretched over the entire width of the moving grid 3 while being positioned inside the outer moving grid 3A and outside the inner moving grid 3B. Therefore, all the openings 5 that have been opened previously are shielded by the screen 4. Even in this state, the inner moving grating 3B can be fixed by operating the lock operation element 35a of the vertical grating 31b, and the outer moving grating 3A can also be fixed.
As a result, the window is provided with crime prevention by the face lattice and is completely blinded by the screen 4.

  In the above embodiment, the moving grating 3 is constituted by the outer and inner two moving gratings 3A and 3B. However, an arbitrary plurality of moving gratings can be used, and an arbitrary number of vertical gratings can be used as these moving gratings. And one or more of them can be used as a screen grid 34 in which the screen 4 is stored in a freely accessible manner. Moreover, it is not necessary to be able to shield the entire surface of the plane lattice frame 2 with the screen 4 interlocked with the movement of the moving lattice, only the main part can be opened and shielded with the screen, and the other parts can be simplified as necessary. It can also be a screen that can be manually shielded and opened.

  Further, in each of the above-described embodiments, the case where the moving gratings 3A and 3B are moved left and right has been described. However, in the present invention, the moving gratings 3A and 3B can be applied to a surface grating that is moved up and down. In this case, the plane lattice shown in the above embodiment may be simply installed with the vertical direction oriented horizontally.
