Description

[Detailed explanation of the invention] [Field of industrial application] This invention relates to a surface lattice that also serves as a shutter.
More specifically, a plurality of parallel blade plates are rotatably arranged in the frame, and the blade plates, which are opened and closed as necessary, have a light shielding function, a shielding function, and a surface lattice function. The objective is to improve a surface lattice that also serves as a shutter.

[Conventional technology]

Conventionally, most windows to which screen lattices are attached have been small, and these windows often do not have enough space to attach storm shutters. Therefore, for example, it is common practice to attach grids to windows near entrances and exits on the hallway side of apartment complexes.

[The problem that the idea aims to solve]

However, as mentioned above, these windows etc.
Since it is difficult to install storm shutters, there have been problems with light blocking and shielding properties.

[Means to solve the problem]

This idea was made with the intention of solving the above problem, and by equipping the surface lattice itself with a light-blocking and shielding function, it was possible to improve the light-blocking and shielding properties of windows where it is difficult to install shutters. A plurality of slats, which stand parallel to each other within the frame, are pivotally connected to the upper and lower window frames via pivots, and each slat is parallel to the window opening surface.
The sides of adjacent blade plates are formed so as to overlap each other, and a pinion is attached to the lower protrusion of the pivot of the blade plate, and one of the racks arranged inside and outside to hold the pinions is attached to each blade plate. This invention proposes a surface lattice that can be used as a rain door, in which the other rack is engaged with the pinion of every other slat, and the operating lever is attached to one of the two racks connected by a connecting plate. .

[Effect]

In other words, the screen lattice that doubles as a storm door of this invention can open and close the slats by operating the operating lever as necessary, and in the closed state, can block light,
This can improve shielding performance.

〔Example〕

Examples of this invention will be described below based on the drawings.

Fig. 1 is a schematic front view of a window equipped with a screen grid of this invention, and Fig. 2 is a schematic cross-sectional view thereof. The main part is composed of a plurality of vanes 2, 2... and a drive means, which will be described later, that controls the opening/closing operation of each of these vanes 2, 2.... In this case, as shown in FIGS. 3, 4, and 6, each of the blade plates 2 is located at one side of both widthwise ends of a hollow rectangular base 4 made of an extruded aluminum member, for example. It has a shape in which a mounting groove 5 for a tight material 6 is provided along it, and a pivot shaft 7 is mounted at a position eccentric from the center in the width direction. The upper and lower protrusions 7a and 7b of this pivot 7 are connected to the frame 1, respectively.
It is rotatably supported by the bearings 8 and 9 of the upper frame 1a or the lower frame 1b, and in a state where each slat 2 is parallel to the window opening surface, the sides of adjacent slats overlap each other. (See Figure 3). The tight material attachment grooves 5, 5 of the adjacent slats 2, 2 are located on opposite sides, and when the slats 2, 2... are closed, the adjacent tight materials 6, 6 are They are placed in close contact with each other to provide good light shielding and shielding. Small mouth lids 30 are attached to the upper and lower ends of the hollow portion of each blade plate, and the upper and lower protrusions 7a,
7b is molded integrally with this mouthpiece 30 from a plastic material. This small palate 30 is the base 4
It is fixed with screws to the screw holes 4a, 4a of 31
is the insertion foot for the hollow part. 32 is the small palate 3
A fin that is integrally molded with 0 and is softer than other parts, and closes the space between the upper and lower frames. In this embodiment, the hollow portion of the vane is filled with urethane foam to improve sound insulation. Note that in FIG. 3, the upper side of the figure is the outdoor side, and in FIG. 4, the left side is the outdoor side.

When the vanes 2, 2,... (The dashed line indicates the fully open state).

Although the drawing shows a case in which two adjacent slats 2, 2 are set as one set and a vertical bar 10 is provided between each set, it is not necessarily necessary to attach the vertical slats 10, and all the slats 2, 2 are arranged as a set. , 2... may be attached.

On the other hand, the driving means 3 has a pinion 11 attached to the downwardly protruding portion 7b of the pivot shaft 7, inner and outer racks 12, 12 that mesh with the pinion 11, and these two racks 12, 12 across the width of the window frame 1. It is composed of connecting plates 13, 13, . . . for simultaneous movement in directions, and an operating lever 14 attached to one of the connecting plates and protruding toward the indoor side. In this case, as shown in FIG.
The pinions 11, 11 of ... are engaged with racks 12, 12 in opposite directions, and the racks 12, 12 facing each other are placed on a connecting plate 13, as shown in FIG. Adjacent slats 2, 2 can be connected to each other by operating one of the connecting plates 13, which are connected and slidably fitted into a guide groove 15 provided in the window lower frame 1b, with the operation lever 14. However, it is possible to rotate in the opposite direction. The rack 12 does not need to be provided with tooth portions over the entire area, and the tooth portion 12a may be provided within a range that allows rotation of the pinion 11 within the opening/closing range of the blade plate 2 (fifth (see figure).

In the above-described surface lattice of the invention, if the blades 2, 2... are to be opened to provide a ventilation function, operate the operating lever 14 and move the rack 12 to the left as shown in FIG. When moved, the adjacent vanes 2, 2 rotate in opposite directions and open, and the adjacent vanes 2, 2 each open in a C shape, so that it has not only a ventilation function but also a blinding function. In addition, when closing the slats 2, 2..., operate the operating lever 14 in the opposite direction to the above and move the rack 12 to the right in FIG. The tight materials 6, 6 between the adjacent slats 2, 2 are parallel to each other.
are closely polymerized with each other. Therefore, good light shielding and shielding performance can be achieved, and the shutter functions as a shutter.
If you move the rack 12 to the left and open it so that each blade is perpendicular to the window opening (as shown by the broken lines in Figure 2), you will have a configuration that allows daylight and ventilation as a normal grid. .

As explained above, according to the planar lattice of this invention, the following effects can be obtained.

In other words, 1. It can be attached to a small window etc. where there is no space to install a shutter, and in addition to the function of a normal screen lattice, it can also be used to block light and
It can have a shielding function and a shutter function.

2. The above-mentioned light shielding and shielding functions can be performed in the closed state of the blades by a simple operation of the operating lever.

3. By leaving the slats open in the middle, they can have a blinding function and a ventilation function.

In other words, in a normal louver, etc., in which each blade rotates in the same direction, the interior is completely visible from the outside when viewed from a direction parallel to the blades, but in this invention, the inside is completely visible from the outside. This allows ventilation to occur while blocking the field of view.
