Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grill shutter formed by connecting a large number of horizontal frames and vertical frames in a grid pattern, and particularly relates to a grill shutter formed between a horizontal frame and a vertical frame. This relates to a grill shutter in which a transparent or translucent glass plate or a synthetic resin plate is fitted in the space.

[Prior Art] As is well known, grill shutters have horizontal frames made of pipes made of iron, non-ferrous metals, stainless copper, etc., which are connected by links and assembled into a grill shape, and one end of this is attached to the ceiling. It opens or closes openings in buildings by attaching it to a horizontal winding shaft, winding it up, and unwinding it.

The grille shutter has many spaces formed by the horizontal frame and the vertical frame, so it has good transparency and
Although it has excellent lighting, there are problems with airtightness, fire prevention, and crime prevention, and there are restrictions on where it can be installed.

Therefore, as seen in Japanese Utility Model Publication No. 31-14055, horizontal bars made of pipes, etc. are connected by links so that they can bend and expand, and spacing pipes are arranged between the links to keep the link spacing constant. A lattice shutter has been proposed in which a thin plate of glass or the like is fitted into sleeves formed on both sides of the link.

[Problems to be Solved by the Invention] However, since the conventional shutter is constructed by assembling the horizontal bars and links in a lattice shape with gaps, and a glass plate is fitted to the sleeve, the visibility is poor. Although they provide daylight, they are not airtight and cannot be installed in locations that require a high degree of airtightness or fire protection.

This invention was made to solve the problems of the above-mentioned conventional type, and its purpose is not only transparency and lighting, but also airtightness, fireproofing,
It is an object of the present invention to provide a grill shutter that exhibits an excellent effect in terms of crime prevention.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention comprises a grid-like structure in which a large number of horizontal frames are arranged in parallel, and a large number of vertical frames are arranged at predetermined intervals between the horizontal frames. In the connected flexible grille shutter, the horizontal frame is comprised of a pair of male-type connecting rods and female-type connecting rods that rotatably engage with each other and have U-shaped openings at opposite ends of the engaging portions. This horizontal frame is connected by a vertical frame constituted by a middle bundle having protrusions formed at the upper and lower ends into which the U-shaped openings are inserted, and having openings at both left and right ends. A transparent or translucent glass plate or synthetic resin plate is fitted into the space formed by the horizontal frame and the middle bundle.

[Examples] Hereinafter, the present invention will be specifically described based on illustrated examples.

FIG. 1 is a partially omitted front view showing one embodiment of the present invention, in which the grill shutter includes a large number of long horizontal frames 1 installed in parallel, and a large number of horizontal frames 1 connected in a grid pattern. It is composed of a glass plate 3 fitted into a space formed by a vertical frame 2.

The horizontal frame 1 is a combination of a male linking rod 11 and a female linking rod 12 that are rotatably engaged with each other in a linking manner. The details of the linking rods 11 and 12 are as shown in FIGS. 2 and 3, and the cross section as a whole is approximately U-shaped, and there are engaging elements on the non-opening side of the U-shaped member having the following correspondence relationship. and form an engaging tongue. That is, an engaging element 11a having a circular cross section is projected from the male engaging rod 11, and a curved groove 11b is formed on the lower surface thereof. On the other hand, an engaging tongue piece 12a having a C-shaped cross section is provided protruding from the female type linking rod 12, and this tongue piece fits into the curved groove 11b and slides smoothly. As an example, a screw hole 12b is formed at the base of the female connecting rod 12, and as shown in FIG. Make sure it stays in place.

U-shaped opening 1 in the linking rods 11 and 12
1d and 12d are arranged facing each other, but between them there is a middle bundle 14 that forms the vertical frame of the grill shutter, and in the part outside the middle bundle,
As shown in FIG. 3, the glass holding frame 15 is fitted.

As shown in FIG. 4A, the middle bundle 14 is a press-shaped member made of aluminum alloy and has tapered surfaces on the front and rear surfaces, and is provided at the U-shaped openings of the connecting rods 11 and 12 that constitute the horizontal frame 1 at the upper and lower ends. Projection 1 that engages with claws 11c and 12c
4a and open at both ends of the through hole 14b.
A clamping frame 13 having glass clamping grooves 13a at both ends as shown in FIG. 4A is fitted into the through hole 14b.

The middle bundle 14, which is a vertical frame with the clamping frame 13 fitted in the through hole 14b in this way, has a pair of linking rods 11,
12, and is fitted from the side into the upper and lower openings 11d and 12d of the horizontal frames 1 and 1 arranged in the vertical direction at a predetermined position, and then the glass restraining frame 15 is fitted into the upper and lower openings of the horizontal frames. . Then, the glass plate 3 with beads 16 attached to the four side edges is held between the glass holding groove 13a of the holding frame 13 fitted to the middle bundle 14 and the glass holding frame 15, and then the next middle bundle 14 is placed from the side. It is fitted between the frames 1 and 1 to sandwich the side edges of the glass plate 3. In this way, the middle bundle 14, which is the horizontal frame 1 and the vertical frame 2, is formed by the glass clamping grooves 13a, 13a of the clamping frame 13 fitted onto the middle bundles 14, 14 in sequence and the glass holding frame 15. The glass plate 3 is held in a rectangular space. Then, as shown in FIG. 8, end plates 18 are applied to both ends of the horizontal frames 1, 1 into which the glass plates 3 are fitted, and these are tightened with screws 19 to secure the entire frame together. and make it a finished product.

Incidentally, any material can be used for the glass plate 3, and when it is made of fire-resistant glass or glass with wire mesh, stronger fire resistance can be imparted.

In the grill shutter of the present invention, as described above, the connecting rods 11 and 12 forming the horizontal frame are engaged in a female shape, and as shown in FIG. Since the female linking rod 12 is configured to rotate clockwise about X, it can be rolled up and stored on the ceiling like a conventional grill shutter.

FIG. 5 shows another embodiment of the present invention, in which the shape of the female-shaped linking rods 21 and 22 constituting the horizontal frame is changed, and in the part outside the middle bundle, the shape is different from that used in the previous embodiment. The glass holding frame 15 is omitted and the U-shaped openings 21a, 2 of the linking rods 21, 22 are used.
This is an example in which the glass plate 3a is directly fitted onto the glass plate 2a via the bead 16a. Nakazuka 24 in this case
is as shown in FIG. 6, indicating that the shape itself can be set arbitrarily.

The member indicated by the reference numeral 34 in FIG. 7 is also a modified example of the middle bundle, and in either case, it can be constructed from a hollow member having voids 24b and 34b, so that the overall weight can be reduced. Become.

However, the vertical and horizontal linking rods and the middle bundle in the present invention may be made of any material;
Preferably, this is manufactured using an extruded molded material made of aluminum alloy. This is because, in addition to being lightweight, the structure of the present invention has a cross-sectional shape suitable for a press molded material.

[Effect of the invention] Since the present invention has the above configuration, it has airtightness,
It has the effect of preventing the intrusion of wind and rain. Furthermore, by making the glass plate that fits into the space formed by the horizontal and vertical frames fireproof and wire-mesh glass, it is possible to provide a shutter that is excellent in terms of fire prevention and crime prevention, making it highly versatile. There is.
