Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a shutter slat in which through-holes provided in the slat material can be easily covered with a band-shaped plate such as a net or a translucent plate.

(Prior Art) In warehouses and the like where foods such as grains are stored, there are shutters in which the upper part of the shutter is opened to ensure ventilation.

This is used not only in large-scale warehouses but also in small-scale warehouses.

Additionally, shutters with windows for daylighting have conventionally existed. This shutter has transparent plates fitted into respective through holes formed in the slat material.

(Problems to be Solved by the Invention) Since the shutter for a warehouse has an opening at the top for ventilation, pests and the like can easily enter the warehouse through this opening. Eating stored food.

They may even breed in warehouses.

There is also a method in which a net is fixed to the opening of the shutter with rivets or the like, but the work is complicated and requires a lot of man-hours, resulting in high costs.

On the other hand, in conventional shutters with transparent windows, transparent plates are manually fitted into the respective transparent holes formed in the slats. These operations were performed separately for each hole, which was troublesome and inefficient.

Therefore, an object of the present invention is to provide a shutter slat in which the through holes of the slat can be easily covered with a mesh.

(Means for solving problems).

The present invention includes the following configuration to achieve the above object.

That is, in order to insert a band-shaped plate such as a net or a translucent plate, two cuts are made in the width direction of the slat material, the part between these cuts is cut and raised to serve as a guide, and the material is straddled over the guide. Alternatively, it is characterized by having a through hole bored at a position that is out of the way.

Furthermore, by increasing the height of the slat material guide on the insertion side of the strip plate and/or widening the width on the insertion side of the strip plate, the strip plate can be easily pushed in.

It is preferable that a band-shaped plate is inserted into the guide of the slat material, and that the band-shaped plate is prevented from coming off by means of a retaining means.

Furthermore, it is preferable that the shutter slat material is used for a part of the shutter.

(effect) Next, the operation of the present invention will be described.

Push the band-shaped plate through the guide along the slat material,
By holding it, the through hole is covered with a strip plate, ensuring ventilation and lighting.

(Embodiments) Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 2 is a perspective view showing the entire shutter.

Moreover, FIG. 1, FIG. 3 - FIG. 5 are a partial back view, a longitudinal cross-sectional view, a side view, and a cross-sectional view of a shutter slat, respectively.

The shutter 10 is formed by connecting a plurality of shutter slats via interlocks.

Further, the shutter 10 is supported by rails 10a, 10a that guide the side ends of each shutter slide 1-. A storage box 10b for winding up and storing the shutter slats is provided at the top of the shutter 10.

In the shutter slat, interlocks 12a and 12b are formed on the upper and lower edges of the slat material 12 for connection.

Among the shutter slats that constitute the shutter 10,
A plurality of through holes 20 are punched out from the surface of the slat material 12 at appropriate locations.

As shown in FIG. 1, a guide is provided to partially cover the through hole 20. As shown in FIG. This guide 22 is bent and formed so as to protrude toward the back surface. That is, the guide 22 has both ends in the longitudinal direction not separated from the slat material 12, and the middle portion thereof is bent toward the back surface of the slat material 12. For this reason, the slat material 12
A space a is ensured between the back surface of the guide 22 and the guide 22, and a push-through hole 23 is formed.

A band-shaped net body 24 can be inserted into the push-through hole 23 of the guide 22 from one end side of the slat material 12 along the slat material 12 . This net body 24 is formed to have approximately the same width as the guide 22.

Furthermore, in order to facilitate insertion of the net 24, the guide 22 is formed with a high opening on the insertion side of the net 24 to form an insertion opening 23a (see FIG. 6).

Furthermore, as shown in FIG. 7, the insertion opening 23 of the guide 22
By forming the a side so that it gradually becomes wider in the width direction of the slat material 12, the mesh body 24 can be pushed in easily.

The net 24 pushed into the insertion hole 23 of the slat material 12 can be prevented from moving by being fixed with fixing means such as rivets.

In this embodiment, the mesh body 24 is pushed through the push-through holes 23 of the slat material 12, but it is also possible to push a transparent or translucent band-shaped translucent plate 26 through the penetration holes 23 of the slat material 12.
(see figure). The net body 24, the translucent plate 26, etc. are referred to as a 4iF-shaped plate.

The procedure for molding the guide 22 will be described. Two cuts are provided in the width direction of the slat material 12, and a portion sandwiched between the cuts is cut and raised to form a guide 22. Then, the through hole 20 is punched out across the guide 22. In this case, the guide 22 is cut and raised, and the through hole 2
0 can be easily drilled in one press process.

In the above embodiment, since the through hole 20 is bored so as to straddle the guide 22, the guide 22 (i.e., securely presses the F-shaped plate against the periphery of the through hole 20, and presses the band-shaped plate and the slat material together) It is difficult to create a gap between the back side of 12.

FIG. 9 is a partial rear view of the slat material showing a modification.

In this example, the guide 22 formed in the slat material 12 of the above embodiment is formed at a position slightly away from the through hole 20. This guide 22 extends 2 times in the width direction of the slat material 2.
It is formed by providing a notch in the book and cutting and raising the portion between the notches. This embodiment has only a slight difference in appearance from the above-mentioned embodiment, but is the same in terms of operation and effect.

In addition, when the net body 24 is attached to the guide 22, a cut is made in the net body 22 near the guide 22, and the cut portion (folded part 24a) is folded back to partially thicken the net body 24.

The net 24 cannot be pushed into the guide 22, and displacement of the net 24 in the left-right direction is prevented.

FIG. 10 and FIG. 11 are a front view and a side view showing a modified example.

In this example, a midway portion of the guide 22 of the above embodiment is removed. In other words, the guide piece 32a has a side cursor shape.
protrude so as to face each other from above and below, and constitute a guide 32. The guide piece 32a of this embodiment is formed by cutting and raising a part of the slat material 12, similarly to the guide 22 described above.

Further, FIG. 12 shows another embodiment, in which the guide 42 has a vertically long side cursor shape, the lower end is integrally fixed to the slat material 12, and the upper end is open. In this case as well, the guide 42 can be attached by inserting a band-like plate such as the net 24 or the translucent plate 26.
It is also possible to attach a strip plate from the upper end of the holder. Further, the same operation and effect as in the above embodiment can be achieved. The guide 42 of this embodiment is formed by cutting and raising a part of the slat material 12, similarly to the guide 22 described above.

In the above embodiment, the guides 22, 32, and 42 were formed by cutting and raising a cut in a part of the slat material 12, but the guides 22, 32, and 42 were formed by cutting and raising a part of the slat material 12. It may be fixed or formed. In this case as well, the same functions and effects as in the above embodiment can be obtained.

Furthermore, the guide may be formed so as to protrude from the front side of the slat material 12.

When the net member 24 is attached to the slat material 12 described above, it can be placed above the shutter 10 in a warehouse or the like to ensure ventilation of food items in the warehouse and prevent pests from entering.

On the other hand, when the translucent plate 26 is attached to the slat material 12, it is possible to bring in light into the building, etc., and if necessary,
It may be placed at an appropriate position on the shutter O.

Next, with reference to FIGS. 13 and 14.

An embodiment in which the net body 24 and the translucent plate 26 are attached to the slat material 12 will be described.

A net body 24 is pushed into the push-through hole 23 along the back surface of the slat material 12 and is fixed to the slat material 12 by a fixing means. Also, the translucent plate 2 is placed so as to overlap the net body 24.
7 is pushed into the push-through hole 23.

The window 27a is partially open. This translucent plate 27 is guided by the guide 22 and can slide.

FIG. 14 shows a case where the through hole 20 of the slat material 12 and the window 27a of the translucent plate 27 are aligned (ventilation possible state), and the first
FIG. 3 shows a case where the window 27a of the translucent plate 27 is shifted from the through hole 20 of the slat material 12 (closed state and daylight state).
