Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shutter that can be used not only as a normal shutter but also as a blind.

[Conventional technology]

Conventionally, this type of shutter was manufactured by, for example, the
As described in Japanese Patent No. 35224, links were arranged on both sides of adjacent slats at different connection positions.

[The problem that the idea aims to solve]

However, according to the conventional method, when the slats are long, not only is there a problem in the strength of the slats in the lateral middle part, but also a pin is essential for connection by links, which requires time and effort. It was hot.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a shutter that can be used as a blind, in which the intermediate portion of a long slat can be easily reinforced, and the slats can be easily connected, that is, the shutter can be constructed easily.

[Means to solve the problem]

The present invention bends the lower part of the main body 2 toward the back side,
An appropriate number of slat bodies are formed on the lower edge thereof to form a winding part 3 that is curved toward the surface, and a locking part 4 with a downwardly hooked tip protrudes from the lower part of the back surface of the main body 2. 1, and curved in opposite directions on the front and back sides, which are tiltably engaged with the winding part 3 of the upper slat body 1 on the upper edge and with the locking part 4 of the lower slat body 1 on the lower edge. The connecting plate 5 has engaging parts 6 and 7 formed therein, and is arranged vertically so that the upper end edge of the lower slat main body 1 is overlapped with the lower end edge of the upper slat main body 1 from the same direction, The slats are successively connected by connecting plates 5 which are placed overlappingly on the back surface of each slat main body 1 at appropriate positions.

[Effect]

The appropriate number of slat bodies 1 constituting the shutter A are arranged so that the engaging parts 6 and 7 formed on the upper and lower edges of the connecting plate 5, which are placed overlappingly on the back surface of the slat body 1, are attached to the upper and lower edges. slat body 1 adjacent to
It is connected to a winding part 3 on the lower end edge and a locking part 4 formed on the back surface so as to be tiltable in order, respectively.
A shutter A is constructed by vertically disposing the lower end edge of the upper slat main body 1 and the upper end edge of the lower slat main body 1 from the same direction.

When the shutter A is suspended, the locking portions 4 of each slat body 1 tend to be close to the line connecting the winding portions 3, so that the slat bodies 1 are stacked on top of each other. becomes.

Therefore, if the shutter A is lowered and stopped when the lower end touches the floor, the same condition as above will occur, and the shutter A will be in the shielding state (A in Figures 2 and 4). .

Next, when shutter A is lowered further with its lower end touching the floor and being prevented from lowering,
Each slat main body 1 is guided by guide rails B, and in order to descend to a substantially fixed position, the winding portion 3
Even if the distance between the slat bodies 1 is narrowed, it is only slightly, and the slat body 1 is pressed by the connecting plate 5 superimposed on the back surface of the slat body 1, and together with the weight of the slat body 1, the slat body 1 tilts. As a result, each slat body 1 is opened (FIGS. 3 and 4, b).

Further, closing of the slat main body 1 and opening of the shutter A are performed by winding up the shutter A.

〔Example〕

Hereinafter, an embodiment of the present invention will be described based on the drawings. A is a shutter that can be raised and lowered, and a suitable number of horizontally long slat bodies 1 are placed between the lower edge of the upper slat body 1 and the upper edge of the lower slat body 1. The edges are stacked one on top of the other in the same direction and arranged vertically. The slat main body 1 is bent in a dogleg shape toward the back surface of the lower part of the main body 2 at the center in the vertical direction, and has a winding part 3 curved toward the surface direction at the lower edge thereof, and a lower part of the back surface of the main body 2. A locking portion 4 with a downward hook-shaped tip is formed protruding from the top. 5 is a short connecting plate having engaging parts 6 and 7 curved in opposite directions on the upper and lower edges, and the engaging part 6 on the upper edge is connected to the winding part 3 of the upper slat main body 1; The engaging portions 7 on the lower end edges are tiltably engaged with the locking portions 4 of the lower slat bodies 1, respectively, to sequentially connect the vertically adjacent slat bodies 1. The connecting plate 5 is attached to the back surface of the slat main body 1 at a proper position so as to overlap. B is a guide rail into which both ends of shutter A are fitted and guides the elevation.
A vertical groove 9 is formed in which a vibration isolator 8, which has a channel-like cross-section and has a winding part 3 of the slat body 1 projecting from both ends thereof, moves up and down. C is a storage box in which the shutter A is wrapped, and 10 is a draining material.

In the embodiment shown in the drawings, the locking portion 4 is connected to the slat body 1.
The one that is integrally formed on the back side of the is shown.
For example, as shown in FIG. 5, a member having a locking portion 4' may be fixed at a proper position on the back surface of the slat body 1.

[Effect of idea]

As mentioned above, the slat main body 1 is sequentially and freely tiltably connected by the connecting plates 5 arranged at appropriate positions on the back surface, so even if the slat main body 1 is long, the intermediate portion can be easily reinforced. In addition, the slat main body 1 can be easily connected, and by using the elongated connecting plate 5 with a window hole formed therein, various effects such as a perfect shutter A for crime prevention can be obtained.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention, and Fig. 1 is a front view, Fig. 2 is a vertical side view of the main part, Fig. 3 is a longitudinal side view when the slat is open, and Fig. 4 A is a view taken along the line X-X.
FIG. 4B is a cross-sectional view taken along the line Y--Y, and FIG. 5 is a perspective view showing another embodiment. 1 is the slat main body, 2 is the main body, 3 is the winding part, 4

Claims (1)

[Scope of utility model registration request] The lower part of the main body 2 is bent toward the back surface, and a winding part 3 curved toward the front surface is formed at the lower edge thereof, and a locking part 4 with a downwardly hook-shaped tip is connected to the lower part of the back surface of the main body 2. A suitable number of slat bodies 1 are formed protruding from the top edge of the slat body 1, and the upper edge of the slat body 1 is tiltable to the winding part 3 of the upper slat body 1, and the lower edge of the slat body 1 is tiltable to the locking part 4 of the lower slat body 1. The connecting plate 5 has engaging portions 6 and 7 curved in opposite directions to be engaged with each other. This shutter doubles as a blind and is constructed by sequentially connecting the slats by connecting plates 5 which are placed one on top of the other in the vertical direction and are placed on the back surface of each slat body 1 in an overlapping manner.
