Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a shutter slat, and more specifically to a shutter slat that prevents damage to the surface of the lighting member and the surface of the slat when winding up the shutter. Regarding.

(Prior Art) Conventionally, shutters installed at entrances and exits of buildings are made of metal plates, and when the shutters are closed, sunlight from outside is blocked, making the interior dark.
Lighting equipment was required for indoor work. Also,
Shutters were opened and closed as needed to let light into the building, but this was cumbersome and inconvenient.

In order to solve this problem, the present inventor punched a through hole in the slat for daylighting, formed a recessed edge around the surface of the through hole, and attached a plurality of locking claws to the recessed edge of the through hole. A shutter slat with a lighting member supported through it has been proposed.
−54194).

Furthermore, there are some shutters in which a window hole for daylighting is bored across adjacent slats, and a daylighting member is installed in this window hole (Utility Model No. 54-
No. 135030). This idea, as shown in Figure 5,
A window hole is provided across any adjacent slat 1, and a window glass 3 is fitted to the inner peripheral edge of the window hole via a thick protective packing 2, and the slat 1 constituting the window hole is folded. This prevents bending. Further, each slat 1 is connected via an interlock 4 at the edge in the width direction.

(Problems to be Solved by the Invention) In the former invention of the above-mentioned conventional examples (invented by the inventor of the present invention), the lighting member fits flush with the slat surface or is recessed. If the slat surface and the lighting member are on the same surface, when the shutter is rolled up,
There is a risk that the surface of the lighting member may be scratched or scratched, which has the disadvantage of impairing the aesthetic appearance and worsening the lighting performance. On the other hand, if the lighting member is fitted by recessing from the slat surface toward the back surface, the surface of the lighting member is less likely to be rubbed or damaged, but there may be dust in the step between the slat surface and the lighting member. They have the disadvantage that they tend to accumulate dirt, impair their aesthetic appearance, and make it impossible to take in sufficient light from the outdoors.

In addition, in the latter device of the above-mentioned conventional example, the protective gasket 2 protrudes from the outer surface of the slat 1, but since the thickness of the window glass 3 is thicker than that of the slat 1, the surface of the window glass 3 extends beyond the slat 1. It protrudes slightly toward the front side of the surface. Therefore, when the shutter is rolled up on a roll and stored, the rubber protective gasket 2 is pushed and deformed by the ridges of the interlock 4, etc., and this deformation mark remains when the shutter is lowered. Sometimes I get tired.
In addition, when the shutter is wound up, the protruding edge of the interlock 4 deforms the protective gasket 2, and at the same time, the protruding edge hits or rubs against the surface of the window glass 3 or slat 1 due to vibrations caused by opening and closing the shutter. Glass 3 may be damaged. For this reason, it also has the disadvantage that the aesthetic appearance of the window glass 3 and the slat 1 surface is impaired. On the other hand, this conventional idea does not predict scratches on the surface of the window glass 3 or the slat 1 at all.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a shutter slat in which the surface of the lighting member is not damaged when the shutter is rolled up.

(Means for Solving the Problems) The present invention has been made in view of the above circumstances, and includes the following configuration.

In other words, by providing transparent holes in the slat material for lighting,
A recessed edge is formed so that the peripheral edge of the through hole is recessed toward the back surface of the slat material, and the recessed edge is made rigid and rigid so that it covers the through hole and the outer surface is flush with the outer surface of the slat material. In a shutter slat fitted and fixed with a light-transmitting resin lighting member, when the shutter is rolled up onto the outer surface of the light-transmitting member, a protruding edge such as an interlock of the slat material is placed on the outer surface of the lighting member. In order to prevent contact and damage to the outer surface of the slat material, the slat material is characterized by being integrally provided with a ridge or a row of protrusions that protrude outward from the outer surface of the slat material and extend in a direction that intersects with the ridge. do.

(effect) Next, we will discuss the effect.

When winding up the shutter, the protruding edge of the interlock or the like on the slat material hits the protrusion on the surface of the lighting member, and the protruding edge does not damage the lighting member and the surface of the slat material.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a partial perspective view of the shutter with the lighting member attached to the slat. FIG. 2 is a partial front view of the slat.

In the drawings, the general reference numeral 10 indicates a shutter, and the shutter 10 is constructed such that shutter slats 12 formed in a band shape are connected to each other in the width direction. The slat 12 has a channel-shaped cross section, and the front surface protrudes outward, while one edge in the width direction curls outward in an arc shape to form an interlock 16.
is formed. The other end edge is formed with an interlock 18 which is curled inward and has a larger diameter than the interlock 16 which is curled outward. For this reason, the shutter 10 is constructed by connecting a plurality of slats 12 in the width direction by fitting the small-diameter interlocks 16 of the slats 12 into the large-diameter interlocks 18 of the adjacent slats 12 from the longitudinal direction. .

Among the plurality of slats 12 constituting the shutter 10 described above, a second slat 12 is placed at an appropriate position.
As shown in the figure, a plurality of rectangular through holes 20 are provided in the longitudinal direction, and a flat lighting member 22 is fitted and locked into the through holes 20.

Note that a recessed edge 30 is formed at the peripheral edge of the through hole 20, and this recessed edge 30 has an L-shaped cross section, and its tip 32 faces inside the through hole 20. A slat 12 in which the lighting member 22 is fitted into the through hole 20
When the shutter 10 with the interlock 16 arranged at an appropriate position is rolled up, the protruding edge of the interlock 16 etc. will touch the lighting member 22.
A protrusion 21 extending in a direction intersecting the protrusion is integrally molded of the same material as the lighting member 22 in order to prevent it from coming into contact with the surface and causing scratches or scratches.

In the figure, the protrusions 21 are provided at both ends so as to be orthogonal to the protrusions. In addition, the protruding portion 21
is formed so as to protrude outward from the surface of the slat 12 when the lighting member 22 is fitted and locked in the through hole 20. Further, the protruding portion 21 may be provided in a direction perpendicular to the protruding edge, or may be provided in a V-shape, etc., and can also have a decorative effect.

On the other hand, a plurality of locking claws 40 are integrally provided on the periphery of the back surface of the lighting member 22 to lock the lighting member 22 to the tip 32 of the recessed edge 30. As shown in FIG. 4, this locking pawl 40 has a semi-sagittal cross section and is vertically protruded from the periphery of the back surface of the lighting member 22. As shown in FIG. The upper part of the locking pawl 40 is a pawl main body 42 having a right triangular cross section, and its slope faces outward with respect to the lighting member 22. A groove 44 having a U-shaped cross section into which the tip edge of the recessed edge 30 of the through hole 20 can fit is formed on the outside of the locking pawl 40 between the pawl main body 42 and the back surface of the lighting member 22 .

Since the present invention is configured as described above,
When fitting the lighting member 22 into the through-hole 20 of the slat 12, the lighting member 22 is supported by the recessed edge 30 of the through-hole 20 in the through-hole 20 on the front side of the slat 12;
Press the lighting member 22 toward the back surface. Then, the locking claw 40 is deformed by the elastic force of the locking claw 40, and
The tip 32 of the recessed edge 30 is fitted into the groove 44,
The lighting member 22 fits into the through hole 20 of the slat 12.
Fixed.

Note that the outer portion of the claw body 42 is inclined so that the locking claw 40 can be easily inserted into the through hole 20. Further, the material of the lighting member 22 may be a transparent or semi-transparent plastic plate, which is rigid and translucent. Also,
It may be colored appropriately.

The present invention is not limited to the above-mentioned embodiments; for example, the through holes and the lighting member are not limited to rectangular shapes, and the protrusions may not be continuous but may be arranged in a row of protrusions; in short, the lighting member It is sufficient to prevent the protruding edges of the interlock etc. from coming into contact with the surface. Furthermore, it goes without saying that many modifications can be made without departing from the spirit of the invention, such as the fitting and fixing of the lighting member to the recessed edge of the slat material without using the locking claws.

(Effects of the invention) The shutter slat of the invention is constructed as described above, and provides the following remarkable effects.

Since the ridges or rows of ridges of the lighting member protrude outward from the outer surface of the slat material, the protruding edges of the interlocks and the like of each slat do not come into contact with the surface of the lighting member when the shutter is rolled up. Therefore, the surface of the lighting member will not be rubbed or damaged.

In addition, since the projections or rows of projections of the lighting member protrude outward from the outer surface of each shutter slat, the projections of the interlock etc. do not come into direct contact with the surface of the slat material. It won't hurt anything.

In a shutter that has already been rolled up, even if there is vibration while the protruding edge of the lighting member is in contact with the protruding edge of the interlock, etc., the surface of the lighting member and slat material may be damaged.
There is no rubbing.

Since the ridges or the row of ridges on the surface of the lighting member are integrally provided, it is also effective in reinforcing the lighting member.

By making the lighting member flush with the surface of the slat without sinking down, the lighting member will not accumulate dust, spoil its aesthetic appearance, and be unable to take in sufficient light from the outdoors.
