[Conventional technology]

As a folding storage shutter of this kind, for example, a shutter body in which a shutter material is link-connected so as to be freely folded in a bellows direction is changed to a rear side through a curved guide continuously arranged above a vertical guide, and a side provided therewith. The suspension link is suspended and supported by the storage guide via the door roller, and the escape link disengaged from the storage guide is alternately alternated to drop the shutter body by its own weight below the storage guide. The storage guide is folded and stored in a hanging manner.

[Problems to be Solved by the Invention]

In this case, the shutter box becomes unnecessary and, for example, the shutter body can be compactly folded and housed in the ceiling space. However, when the shutter material is sequentially sent out to close the folded and housed shutter body, A space for sending the shutter material is created by applying a pulling force so that the delivered shutter material draws the stored shutter material toward the curved guide side, and the shutter body approaches the curved guide. Is difficult to obtain, closing is not performed smoothly,
There is a possibility of leaving the problem that closure is impossible.

The present invention has been made in view of the above circumstances, and the problem to be solved is to prevent the folded and housed shutter body from approaching the conversion guide as much as possible, and to ensure smooth delivery when the shutter body is closed. Another object of the present invention is to provide a device for preventing the folding storage shutter from coming near.

[Means for solving the problem]

In view of the above problems, the present invention uses a curved guide that supports the shutter main body, and allows the escape hinge to bend to the front and back sides in order to accommodate the direction change and the suspended folding storage. A three-divided hinge member is used, and the shutter member is horizontally held between the lifting hinge and the three-divided central hinge member of the escape hinge while being supported under the curved guide, and the shutter member is housed. The shutter can be moved straight to the guide side, and the shutter hinge is pushed forward in the direction away from the curved guide by this shutter material until the central hinge member passes through the curved guide. As far as possible from the guide to reduce the possibility of getting closer,
Even if the pulling force is applied when the shutter body is closed, the positional relationship between them is secured as much as possible to prevent the shutter body from approaching and to eliminate the troubles such as defective or impossible delivery of the shutter body. It was done like this,
That is, according to the present invention, the shutter body in which the shutter material is hingedly foldable in a bellows shape is turned to the back side through the curved guide that supports the shutter body continuously arranged on the upper part of the vertical guide, and the shutter body is alternately alternated. The hanging hinge is suspended and supported by the storage guide following the curved guide via the side door roller provided on the hanging hinge, and the escape hinges that are not engaged with the storage guide are alternately placed on the curved guide. A folding storage shutter in which the shutter main body is dropped and escaped by passing it under the space between the storage guides after passing and is folded and stored in the storage guide in a suspended manner. The front hinge member and the rear hinge member that connect the connecting parts to each other so that they cannot be bent on the front side and are bent on the back side, and the connecting parts between them are bent to the back side. Functioning, a central hinge member that is flexibly connected to the front side and a three-divided hinge member that allows the adjacent shutter member to bend to the front and back sides, and the hanging hinge that precedes the storage guide and the trailing hinge. The hinge connection of the shutter material between the central hinge members in the above-mentioned three divisions of the escape hinge can be bent in one direction toward the front side, and the vertical guide is used to suspend the vertical guide to the next position by the hoisting means that raises the lower end of the shutter body. The pushing force of the hinge changes the direction of the escape hinge in the curved guide and presses it toward the storage guide in the state of being supported by the curved guide so that the shutter material between the preceding hanging hinge and the central hinge member is leveled. The folding hinge is characterized in that the shutter hinge can be moved straight toward the storage guide until the escape hinge passes through the curved guide.

〔Example〕

The present invention will be described in more detail with reference to the drawings shown in the following embodiments. A is a foldable storage shutter, and the foldable storage shutter A is a shutter body 1 in which a shutter member 2 is hingedly connected in a bellows-like foldable manner. A winding guide for supporting the shutter body 1 continuously arranged above the vertical guide 16 by winding means for raising the lower end thereof, in this example, by winding the wire 12 suspending the lower end.
The direction of the suspension hinge 3 is changed to the back side by means of the side end door wheel 11 provided on one of the alternating hinges 3 and the suspension hinge 3 is suspended and supported by the storage guide 18 following the curved guide 17, and the other alternate Then, the exit hinge 4, which is not engaged with the storage guide 18, passes through the curved guide 17 and then falls downward by its own weight between the storage guides 18 so that the shutter main body 1 falls and escapes, and the storage guide 18 is folded and stored in a hanging manner. The leading hinge member 5, the trailing hinge member 7, and the trailing hinge member 7 that connect the escape hinge 4 to the shutter member 2 such that the connecting portions with the shutter member 2 are not bendable on the front side and are bendable on the back side at this time. The adjacent shutter member 2 is bendable to the front and back sides by forming a three-divided hinge member by a central hinge member 6 which connects the connecting portion between these members to each other so that the back side cannot be bent and the front side is bendable. The hinge connection of the shutter 2 between the central hinge member 6 in the above-mentioned three divisions of the hanging hinge 3 preceding the storage guide 18 side and the escape hinge 4 subsequent thereto is allowed to be mountain-folded and bent to one side on the front side. When the wire 12 of the hoisting means winds up, the vertical guide 16 is lifted. The lifting force of the next lifting hinge 3 changes the direction of the escape hinge 4 in the curved guide 17 and stores it in the state of being supported by the curved guide 17 as a lower support. By pressing it toward the guide 18, the shutter material 2 between the preceding hanging hinge 3 and the central hinge member 6 is held horizontally, and the escape hinge 4 is bent by the curved guide 17.
The shutter member 2 can be moved straight toward the storage guide 18 side until it passes.

In this example, the shutter body 1 is made of aluminum extruded material and has a pair of support shafts 9 which can be connected to each other in upper and lower end portions in opposite directions.
A shutter material 2 having a bearing and a bearing 10 is used, and a hinge 3 for suspension and a hinge 4 for escape are made of aluminum extruded material, respectively.
It is hinged by and and can be folded in a bellows shape.
The hanging hinge 3 and the escape hinge 4 have the same configuration but are used in reverse so that the members are shared.

That is, these hinges 3 and 4 are formed by using a three-divided hinge member including a leading hinge member 5, a central hinge member 6 and a trailing hinge member 7 in this example, and connecting adjacent shutter members 2 to each other through these. The leading hinge member 5 has the bearing 10 and the support shaft 9 from the leading side in the same direction, the central hinge member 6 has the pair of bearings 10 in the same direction, and the trailing hinge member 7 has the pair of support shafts 9 in the opposite direction. Each of them is made of aluminum extruded material, and at this time, each support shaft 9 and the bearing 10 including the shutter material 2 are mutually connectable, and at the same time with respect to the pair of bearings 10 of the central hinge member 6. The support shaft 9 of the leading hinge member 5 and the support shaft 9 of the trailing hinge member 7 are connected so as to be symmetrical with respect to the central hinge member 6 in the longitudinal direction of the shutter body 1, and the front and rear surfaces of the central hinge member 6 are connected. Leading hinge member 5 on one side And the following hinge member 7 are set to be bendable rotated.

In this way, in this example, the hanging hinge 3 and the escape hinge 4 which are common to each other are the pair of opposite directions of the support shaft 9 and the bearing 10.
Of the above, the shutter members 2 are arranged such that the bearing 10 is on the upper side, that is, the leading side, and the support shaft 9 is on the lower side, that is, the trailing side, and in the hanging hinge 3, the front and rear surfaces of the central hinge member 6 are arranged. In the escape hinge 4, the front hinge member 5 is rotated so as to be bent toward the front side of the central hinge member 6 so as to be rotated and bent toward the rear side. Attach the support shaft 9 of the shutter member 2 to the remaining bearing 10,
The bearing 10 of the shutter member 2 is fitted and connected to the remaining support shaft 9 of the trailing hinge member 7, and the bellows-like foldable hinge connection of these shutter members 2 is performed.

Therefore, in the shutter body 1, the preceding hinge member 5,
The trailing hinge members 7 make the connecting portions with the shutter member 2 non-bendable on the front side so that they can be bent on the back side, and the central hinge member 6 makes the connecting portions with these members not bendable on the rear side and bendable on the front side. In this example, the adjacent shutter member 2 is made to be bendable by 270 °, and the relationship between the shutter member 2 and the central hinge member 6 in the preceding hanging hinge 3 and the subsequent escape hinge 4 is described below. The hinge member is designed to be mountain-foldable and bendable to one side on the front side so that the shutter member 2 can be held horizontally between the hanging hinge 3 and the central hinge member 6 in the storage guide 18. To become.

At this time, the preceding hanging hinge 3 is suspended and supported by the storage guide 18 via the side end door wheel 11, and the next hanging hinge 3 is held.
The wire 12 of the hoisting means winds up the vertical guide 16 through the side door roller 11 as well, and pushes up the shutter material 2 above it, as well as the bearing 10 of this shutter material 2 for escape. As the support shaft 9 of the trailing hinge member 7 of the hinge 4 rotates and supports it,
The shutter body 1 by the curved guide 17, that is, the shutter material 2 and the escape hinge 4 is supported between the hanging hinge 3 and the central hinge member 6 in a state of being supported below, and the shutter material 2 reaching the storage guide 18 is horizontally held. The shutter material 2
The shutter member 2 is released from its holding state after the escape hinge 4 passes through the curved guide 17 that supports the escape hinge 4 and the escape hinge 4 is lowered between the escape guides 18 while allowing the escape hinge 4 to move straight toward the accommodation guide 18. Then, the shutter body 1 falls and escapes, and the folding and storage thereof are performed.

Reference numeral 8 in the figure is used in this example so that the radius of the direction change in the shutter body 1 can be made as small as possible to make the overall configuration compact, while the folding width can be made small when storing to effectively use the ceiling space. Therefore, the shutter member 2 has a narrow width, and two shutter members 2 are used between the hanging hinge 3 and the escape hinge 4 to support the shaft 9 and the bearing.
Reference numeral 13 is an auxiliary hinge adapted to be fitted and connected to each other, 13 is a wire winding shaft, 14 is a motor, 15 is a pulley for suspending the wire 12 as a hoisting means, and 19 is a ceiling plate.

In the folding storage shutter A of the present embodiment having the above-mentioned configuration, the shutter member 2 is held horizontally and is allowed to move straight, so that the hanging hinge 3 preceded by the shutter member 2 is moved from the curved guide 17. By pressing in the separating direction, the position of the shutter body 1 is separated from the curved guide 17 to reduce the possibility of being closer, and even if the shutter body 1 receives a pulling force when it is sent out at the time of closing, It is possible to secure the positional relationship, prevent the shutter body 1 from coming closer, and prevent troubles such as defective delivery and inability due to this.

Although the illustrated example is as described above, each specific material, shape, structure and relationship of the shutter body, shutter material, vertical guide, curved guide, storage guide, suspension hinge, escape hinge Additions and the like can be modified in various ways without departing from the spirit of the invention.
