Description

[Detailed Description of the Invention] Purpose of the Invention (Industrial Application Field) This invention relates to a shutter installed in a doorway or a window of a house, and in particular, when the shutter is opened, the slats are folded in a state of being laminated on the upper part. It relates to a folding shutter that is stored in.

(Prior Art) Conventionally, both sides of a large number of independent slats as one type of shutter are linked and supported by a link mechanism, and the slats are moved up and down by expanding and contracting the link mechanism in the guide rail, and each slat is in the same phase. There is a type in which the slat can be rotated from the horizontal direction to the vertical direction, and when the slats are opened, the slats can be folded into the storage case provided above the slats. In such a shutter, if the support position of the uppermost slat is fixed and a storage space for all the slats is secured below it, multiple slats that are located in the storage case will not be removed even when the slats are pulled down to the lowest limit. Existent and unreasonable. Therefore, the support position of the uppermost slat can be moved up and down in the storage case, and when the slat is pulled down to the lowermost limit, the uppermost slat is lowered to the vicinity of the opening of the storage case, so that it is always in the storage case. A structure that eliminates the slats that have been used has also been proposed.

(Problems to be solved by the invention) However, in the convoluted shutter as described above, when the slat is lowered to the lowest limit and is vertically rotated to the fully closed state, the opening and the uppermost stage of the storage case are closed. Since a large gap is created between the slat and the slat, rain and dust may enter the storage case and cause a failure of the shutter drive means such as a motor provided in the storage case.
There is a problem that the shutter driving means in the storage case comes into the field of view and looks bad.

Configuration of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, this invention has a link mechanism inside the guide rails located on both sides of the slat, and the upper and lower ends of the multi-slat are connected to each other. The link mechanism is supported by the link mechanism, and the link mechanism can be expanded and contracted by the driving means installed in the storage case.The slat is raised and lowered and rotated based on the expansion and contraction of the link mechanism, and the link mechanism is contracted to provide it on the upper part of the guide rail. In the folding shutter in which the slats are stacked on the storage case and can be folded, the top cover 6 that covers the opening 4a of the storage case 4 when the shutter is fully closed is provided at the upper end of the link mechanism 5.

(Operation) By the above means, the opening 4a of the storage case 4 is covered with the top cover 6 even if the slat 3 is vertically rotated.

(Embodiment) An embodiment embodying the present invention will be described below with reference to the drawings. As shown in FIG.
A pair of guide rails 2 are provided upright on both sides, and between the guide rails 2, a plurality of slats 3 are supported so as to be vertically movable and rotatable. A storage case 4 that opens downward is provided above the folding shutter 1 so that the slats 3 that are folded up can be stored.

An elevating and rotating mechanism for the slat 3 is provided in each of the guide rails 2. That is, as shown in FIGS. 4 to 6, a link mechanism 5 that is vertically expandable and contractable is disposed in the guide rail 2, and the link mechanism 5 supports a large number of slat 3 stages. As with the slats 3, both ends of a top cover 6 located between the guide rails 2 are supported on the upper end of the link mechanism 5. The top cover 6 is formed of an extruded die member having a cross-sectional shape as shown in FIG. 1, and sealing pieces 7 extending vertically along the inner side surfaces of the storage case 4 are formed on both front and rear edges, and an upper surface middle portion is formed. Has two ridges 8 extending upward. The top cover 6 has a size capable of substantially covering the opening 4a of the storage case 4 as shown in FIG.

Further, as shown in FIG. 5, the upper end of the link mechanism 5 is suspended and supported by a slide carriage 9, and the slide carriage 9 has a lower limit at a position where it abuts on a top limiter 10 fixed to an inner surface of the guide rail 2. It is supported by the guide rail 2 so as to be able to move up and down.

A sprocket 11 rotatably driven by a motor (not shown) disposed in the storage case 4 is provided at the upper end of the guide rail 2, and the sprocket 11 is supported by the guide rail 2 so as to be movable only in the vertical direction. Chain 12 is hung. A guide rail 2 is attached to one end of the chain 12.
A slide tilter 13 supported only up and down is attached to the slide tilter 13, and the link mechanism 5 is attached to the slide tilter 13.
The lower ends of are connected. Then, when the chain 12 is moved up and down based on the driving force of the motor, the slide tilter 13
Is moved up and down to expand and contract the link mechanism 5, and based on the expansion and contraction of the link mechanism 5, the slats 3 are moved up and down as shown in FIGS. 4 and 5.

Each slat 3 is rotatably supported by the link mechanism 5 and is also connected to a tilter guide 15 via a tilt arm 14, and each tilt arm 14 is supported by the tilter guide 15 so as to be movable in its longitudinal direction. The tilter guide 15 is rotatably supported by the plurality of support levers 16 with respect to the guide rail 2 and is connected to the guide rail 2 by a coil spring (not shown). It is designed to be held at the position shown in. An engagement shaft 17 connecting the lower end of the tilter guide 15 and the support lever 16 is slightly extended in the longitudinal direction to engage with the slide tilter 13. Then, when the slide tilter 13 is lowered and the engagement shaft 17 is pressed downward, the tilter guide 15 moves to the fifth position.
From the state shown in the figure to the state shown in FIG. 6, each slat 3 is rotated via the tilt arm 14 in the same phase from the horizontal direction to the vertical direction.

Now, in the folding shutter 1 configured as described above, when the link mechanism 5 is folded upward as shown in FIG. 4, each slat 3 is folded in the storage case 4 as shown in FIG. And in this state, storage case 4
The opening 4a of the is substantially covered with the slat 3 at the lowermost stage to prevent rain and dust from entering the storage case 4. When the chain 12 is driven from this state and the slide tilter 13 is lowered, the slats 3 and the top cover 6 are integrally lowered, and the upper end of the link mechanism 5 is brought into contact with the top limiter 10 and further lowered. When blocked, the link mechanism 5 is gradually extended downward, and the intervals between the slats 3 are expanded as shown in FIG. When the slide tilter 13 engages with the engagement shaft 17 to rotate the tilter guide 15, the slats 3 are rotated in the same phase from the horizontal direction to the vertical direction as shown in FIG. Fully closed.

At this time, the top cover 6 is located in the opening 4a of the storage case 4 as shown in FIG. Therefore, since the opening 4a of the storage case 4 is almost covered with the top cover 6 and rain and dust can be prevented from entering the storage case 4, a motor or the like arranged in the storage case 4 can be prevented. It is possible to prevent a failure of the driving means.

Although the dedicated top cover 6 is provided at the upper end of the link mechanism 5 in the above embodiment, the slat 3 may be supported and fixed in the horizontal direction at the upper end of the link mechanism 5. Further, this invention is not limited to one in which the upper end of the link mechanism 5 is supported so as to be able to move up and down in the storage case 4 as described above, but the top cover is implemented even if it is applied to a convoluted shutter in which the upper end of the link mechanism 5 is fixed in the storage case 4. 6. It is possible to protect the upper shutter drive means from rain and dust.

Effect of the Invention As described in detail above, this invention prevents rain and dust from entering the storage case 4 in advance in the convoluted shutter in which the slat is rotated from the horizontal direction to the vertical direction to be in the fully closed state. It is possible to prevent the drive means such as a motor provided in the storage case from breaking down due to rain or dust, and to improve the appearance by cutting off the drive means in the storage case from the field of view. Shows excellent effects.
