Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a component of an opening / closing device for guiding and moving an opening / closing body formed by including a sheet-like member into a pair of grooves to open and close it. According to the method of installing the opening / closing body of the opening / closing device when installing the opening / closing body, when replacing an old opening / closing body or a damaged opening / closing body with a new opening / closing body, the currently installed opening / closing body must be used for disaster prevention, etc. When performing work to replace the opening and closing body for the purpose of, or to attach the components other than the opening and closing body of the opening and closing device to the building body in advance, and then attach the opening and closing body to complete the opening and closing device It can be used when adopting various work procedures.

[0002]

BACKGROUND ART In recent years, sheet-shaped members (cloth screens) having excellent fire resistance, heat shielding properties, waterproof properties, etc. have been developed. As a result, these sheet-shaped members are formed as opening / closing devices for partitioning adjacent spaces. Devices equipped with openable and closable bodies have been adopted.

In particular, as a disaster prevention shutter for fire prevention, smoke prevention, etc., it has been customary to use a heavy shutter formed by connecting metal slats in the past. Since it is difficult to carry and handle such as mounting work, it is desirable to use an apparatus (also referred to as a sheet shutter) including the opening / closing body formed of the sheet-shaped member as described above.

[0004]

However, when the opening / closing body formed of the sheet-shaped member is used, the opening / closing body may be damaged by repeating the opening / closing operation, and the sheet-shaped member is old. It cannot be denied that there is a possibility that it will deteriorate and the intended purpose will not be achieved.
Therefore, it may be necessary to remove the opening / closing body once attached to the opening / closing device and replace it with a new opening / closing body.

Further, there are cases where it is desired to further improve the performance of the opening / closing body currently installed, or to replace it with an opening / closing body having another purpose or function.

Further, when the switchgear is attached to a building, a work procedure in which components other than the switchgear of the switchgear are attached to the building body in advance, and then the switchgear is attached to complete the switchgear. It is also possible to adopt such a work procedure, and when adopting such a work procedure, it is desired to carry out the work by a method in which the opening / closing body can be easily attached even afterward.

An object of the present invention is to provide a method for attaching an opening / closing body of an opening / closing device, which can easily and quickly attach the opening / closing body to a pair of already installed groove portions even afterward.

[0008]

According to the present invention, there is provided an opening / closing member which is arranged at a boundary position between adjacent spaces and includes a sheet-like member for partitioning these spaces, and a peripheral portion of a partition surface by the opening / closing member. And a pair of grooves for guiding the opening and closing movements of the opening and closing body by engaging and inserting both side edge portions of the opening and closing body to each other. After inserting a part of the portion into the pair of grooves, by moving this insertion portion along the pair of grooves while maintaining the insertion state, the remaining part of the both side edge parts of the opening / closing body (the remaining part (All or a part of) is sequentially inserted into the pair of groove portions.

Here, the sheet-like member may be of any kind as long as it is flexible, such as a cloth screen, vinyl sheet, urethane sheet, etc., but is used for disaster prevention purposes such as fire prevention and smoke prevention. In this case, for example, silica cloth or glass cloth sprayed or coated with a fireproof coating material or a waterproof coating material as a fireproof coating material can be preferably used. Further, the sheet-like member may be combined with a reinforcing metal wire material such as a wire mesh, and if such reinforcement is performed, the sheet is not only used for disaster prevention purposes but also in normal use. Is less likely to break and the durability of the sheet can be improved, which is effective.

Further, the opening / closing body is not limited to one that is used as a single sheet without stacking the sheet-shaped members in the thickness direction, and may be formed of, for example, a bag-shaped sheet-shaped member. Alternatively, a plurality of sheet-shaped members may be laminated in the thickness direction to form a layer.
The opening / closing body does not need to be formed by one continuous sheet-like member even when viewed two-dimensionally. For example, if the opening / closing body is an opening / closing device in which the opening / closing body moves up and down. It may be formed by connecting a plurality of sheet-like members arranged side by side in the vertical direction.), Or in a direction intersecting the opening / closing direction (for example, the opening / closing body moves up and down). If it is an opening / closing device, it means the left-right direction.), A plurality of sheet-shaped members arranged side by side may be connected to each other,
Further, it may be formed by connecting in two directions like a grid.

Further, a part of the opening / closing body may be formed with an entrance / exit (an emergency exit in the case of a disaster prevention device) through which a person or the like can come in and out with the opening / closing body closed.

The term "opening / closing body formed by including a sheet-like member" does not require that all parts of the opening / closing body are formed of sheet-like members. A metal seat plate may be provided, and a metal reinforcing member or a connecting member for connecting a sheet-like member may be provided at an intermediate position in the opening / closing direction of the opening / closing body. Also, the portion of the opening / closing body on the leading edge side in the closing direction may be formed of a sheet-shaped member, and the portion of the storage portion side may be formed of a member other than the sheet-shaped member (for example, metal slats). At least a part of the opening / closing body may be formed of a sheet-shaped member.

Further, the groove is not limited to a guide rail mounted so as to project to the space side from the surface of the body such as a wall or floor or ceiling, or a guide rail embedded in the inside of these bodies. For example, it may be a concave portion formed directly on the body.

Further, "insertion" in "inserting a part of both side edge portions of the opening / closing body into a pair of grooves" and "sequentially inserting the remaining portions of both side edge portions of the opening / closing body into a pair of grooves" , Means insertion from the opening portions (opening portions formed along the groove portions) of the pair of groove portions that are arranged to face each other,
It does not mean insertion from an opening portion formed at an end portion of the groove portion (for example, an opening portion formed at an upper end portion 45 of guide rails 41 and 42 of FIG. 2 described later).

In the present invention as described above, after a part of both side edge portions of the opening / closing body is inserted into the pair of groove portions, the inserted portions are moved along the pair of groove portions while maintaining the inserted state. Since the opening / closing body is formed to include the sheet-like member, the remaining portions of both side edge portions of the opening / closing body are naturally inserted into the pair of groove portions in a manner that they are dragged by the insertion portion. At this time, the push-insertion by the operator's hand may be assisted.

Therefore, the opening / closing member can be easily and quickly attached to the already installed pair of groove portions even afterward, so that the opening / closing member can be easily replaced. It is also possible to install work elements other than the opening / closing body among the components of the opening / closing device in advance on the building body, and then attach the opening / closing body to complete the opening / closing device. The purpose is achieved.

In the present invention, the "part of both side edge portions of the opening / closing body" which is first inserted into the pair of groove portions may be both end portions of the edge portion of the opening / closing body on the side of the storage portion (for example,
In the case of FIG. 10, which will be described later), both ends of the closing direction tip edge portion of the opening / closing body (edge portion on the side opposite to the storage portion side) may be used,
Alternatively, it may be an intermediate position in the opening / closing direction of both side edge portions (edge portions to be inserted into the pair of groove portions) of the opening / closing body, and further, each of these portions may be inserted at two or more locations together. Good (for example, in the case of FIGS. 20 and 21 described later).

However, it is preferable to do the following in terms of easier mounting work. That is, in the opening / closing body mounting method of the opening / closing device described above, the opening / closing device includes a storage portion for storing the opening / closing body, and a part of both side edge portions of the opening / closing body to be inserted into the pair of grooves is used for storing the opening / closing body. It is preferable that the attachment method is such that the movement along the pair of groove portions at both ends of the edge portion on the side of the portion is movement toward the storage portion.

Here, the storage system in the storage section may be a winding type in which the opening / closing body is wound around the winding section, or a folding type in which the opening / closing body is folded and stored (for example, as described later). In the case of FIG. 20, etc.), or may be of a slide type in which it is fed and stored as it is without being rolled or folded.

Further, when both ends of the edge portion of the opening / closing body on the side of the storage portion are inserted and moved in the direction of the storage portion, both ends of the edge portion on the side of the storage portion of the opening / closing body are moved. When inserting the parts into the pair of grooves, the end edge portion of the opening / closing body on the side of the storage part is arranged in the partition surface in a state of being inclined with respect to the pair of grooves, and then rotated in the partition surface. It is preferable (for example, in the case of FIGS. 11 and 12 described later).

Here, the phrase "the end edge portion of the opening / closing body on the side of the storage portion is disposed in the partition surface in a state where the end edge portion is inclined with respect to the pair of groove portions and then this is rotated in the partition surface" means opening and closing. After inserting either one of the two ends of the edge part of the storage part side of the body into one groove, place the entire edge part of the opening / closing part on the storage part side diagonally and place it in the partition surface. Then, subsequently, the case where the whole is rotated within the partition surface and the other end is inserted into the other groove (the case of FIGS. 11A to 11C described later, which is hereinafter referred to as case 1). ) And the end portion of the opening / closing body on the side of the storage portion of the opening / closing body by inserting one of the two end portions of the end portion of the opening / closing body on the side of the storage portion into the groove. Place the entire part in the partition surface, and then rotate this entire part in the partition surface to insert the other end into the other groove. If you (the case will be described later shown in FIG. 11 (B) and (C), hereinafter referred to as Case 2.)
After arranging the whole edge portion of the opening / closing body on the side of the storage portion in a slanted state in the partition surface, the entire end portion is rotated in the partition surface so that both ends thereof are formed into a pair of groove portions substantially simultaneously or sequentially. The case of insertion (the case of FIG. 12 described later, and hereinafter referred to as case 3) is included. That is, the cases 1 and 2 are operations in which the so-called fallow work and the rotation work are combined, and the case 3 is only the rotation work.

When such an insertion is performed, a harder part than the sheet-like member (for example, a winding part provided in the storage part and an opening / closing part) is provided at the end portion of the opening / closing body on the storage part side. Even if there is a connecting member or the like for connecting with the body, this can be easily inserted into the pair of groove portions.

Further, when inserting both ends of the edge portion of the opening / closing body on the side of the storage portion into the pair of grooves, the cases 1 to 3 described above are inserted.
It is not an insertion method involving rotation work such as, for example, if it is possible to bend or bend relatively large even if there is a harder part than the sheet-like member, insert it by bending or bending. Alternatively, if the depth of the pair of grooves is large, the pair of grooves may be inserted only by a simple sparing work without rotating work (in the case of FIG. 19 described later). However, it is preferable to use an insertion method involving a rotating operation like the cases 1 to 3 above, and by doing so, even if there is a hard portion that cannot be greatly curved or bent, it can be easily inserted. In addition, the depth of the pair of groove portions can be reduced.

Further, in the case of the winding type storage in which the storing section is provided with the winding section for winding the opening / closing body, the following two methods are available for connecting the winding section and the opening / closing body. It can be preferably adopted.

That is, as a first method, when moving both ends of the edge portion of the opening / closing body on the side of the storage portion toward the storage portion, the winding for winding the open / close body provided in the storage portion is performed. Storage of the open / close body by connecting the take-up part and the edge of the open / close body on the side of the storage part with a bendable tow tool and rotating the take-up part in this state to wind the tow tool around the take-up part. There is a method of pulling the end edge portion on the side to the position of the winding portion, then connecting the edge portion on the storage portion side of the opening / closing body and the winding portion, and removing the pulling tool.

Here, as the bendable pulling tool, for example, a cord, a band, a rope, a wire or the like can be used. Further, traction means pulling in the direction of the winding unit, and if the opening / closing body moves in the vertical direction, and if the winding unit is an opening / closing device installed above, it means lifting. The present invention is not limited to this, and for example, if the opening / closing body is an opening / closing device that moves in the left-right direction or the horizontal direction, it means pulling in the left-right direction or the horizontal direction.

When such a bendable towing tool is used, it is possible to easily connect the edge portion of the opening / closing body on the side of the storage portion to the winding portion, and the winding portion already installed. The opening / closing body can be easily and quickly attached to the portion even afterward.

As a second method, when moving both ends of the edge portion of the opening / closing body on the side of the storage portion toward the storage portion, a winding for winding the open / close body provided in the storage portion. A pulling member that can be wound around the winding unit is provided in advance in the winding unit, and the pulling member is extended from the winding unit. Then, in this state, the ends of the pulling member and the opening / closing body on the storage unit side. There is a method of connecting the edge portion and then winding the pulling member around the winding portion by rotating the winding portion.

Here, the pulling member that can be wound around the winding portion is, for example, a belt-shaped or string-shaped hanging member formed of metal or the like, a plurality of slats connected in series, or a plurality of panels. And a plurality of pipe members connected to each other by a link member, a sheet-shaped member, and the like. The pulling member differs from the pulling tool of the first method in that the pulling member forms a part of the opening / closing device without being removed while being wound by the winding unit. However, the traction member does not constitute a part of the opening / closing body that partitions the space.

When such a pulling member is used, it is possible to easily connect the end portion of the opening / closing body on the side of the storage portion and the winding portion through this pulling member, and the above-mentioned first member is used. As in the case of using the towing tool of the method of (1), the opening / closing body can be easily and quickly attached to the already installed winding section even afterward.

In particular, since the pulling member does not need to be removed after being wound up on the winding section, it is possible to mount the opening / closing body without arranging an operator near the storage section.

Further, in order to attach a retaining member for preventing both side edge portions of the opening / closing body from coming off from the pair of groove portions, the following is preferable. That is, after completing the insertion of the remaining portions of the both side edge portions of the opening / closing body into the pair of grooves, the winding section for winding the opening / closing body provided in the storage section is rotated to wind the opening / closing body. The winding part once, and then, while rotating the winding part in the reverse direction to extend the opening / closing body, a retaining member for preventing the edge portions on both sides of the opening / closing body from coming off from the pair of grooves is provided on both sides of the opening / closing body. It is preferable to attach to the edge portion.

If the retaining member is attached by such a method, it becomes possible to attach the retaining member outside the pair of groove portions, which facilitates the work.

Further, in the opening / closing body, a hard portion longer than the space between the entrances of the pair of grooves is provided at a portion other than the end edge portion of the opening / closing body on the accommodating portion side (intermediate position in the opening / closing direction or the accommodating portion). In the case of one on the opposite side edge portion), the following is preferable. That is, when inserting such a hard portion into the pair of groove portions while sequentially inserting the remaining portions of the both side edge portions of the opening / closing body into the pair of groove portions,
It is preferable to arrange the hard portion in the partition surface in a state of being inclined with respect to the pair of groove portions, and then rotate the hard portion in the partition surface.

Here, the hard portion means a portion that is harder than the sheet-like member, and serves as a connecting member when the plurality of sheet-like members are connected to each other to form an opening / closing body, or What acts as a reinforcing member, and moreover, those that serve as both a connecting member and a reinforcing member, such as a middle crosspiece in FIGS. 3 to 6 described later or its constituent parts, a seat plate or its constituent parts, etc. Is mentioned.

By inserting the hard portion in the portion other than the edge portion of the opening / closing body on the housing portion side by such a method, the above-mentioned method for inserting the edge portion of the opening / closing body on the housing portion side (case) It becomes possible to perform the work in the same procedure as 1 to 3), and the work of attaching the opening / closing body can be facilitated.

Further, in the opening / closing body mounting method of the opening / closing device described above, when the opening / closing body is formed by connecting a plurality of sheet-like members arranged side by side in the opening / closing direction to each other, The following is preferable. That is, when sequentially inserting the remaining portions of the both side edge portions of the opening / closing body into the pair of groove portions, a plurality of sheet-like members should be connected in order according to the progress of the insertion work. Preferably.

Here, "according to the progress of the insertion work" means that when the insertion work of one sheet-shaped member is mostly completed or completed, the next sheet-shaped member is connected. , Which means to continue the insertion work.

When such a split type insertion method is adopted, when an opening / closing body formed of one large sheet-shaped member is handled, or when a plurality of sheet-shaped members are connected in advance, Compared with the case of inserting all at once, the sheet-shaped members that are connected one by one are small, so that they are easy to handle and can be easily attached.

In the above, as an opening / closing device to which the opening / closing body attaching method of the present invention can be applied, a disaster prevention device for performing fireproofing or smokeproofing, such as a fireproofing or smokeproof shutter device or a smokeproof hanging curtain, is suitable. However, it is not limited to this, for example, for devices having various purposes such as sunshades, rain shelters, partitions, blindfolds, entry prevention plates, waterproof plates, for example, ordinary shutter devices, blind devices, awning devices, etc. The present invention can be applied to any opening / closing device that has an opening / closing body including a sheet-shaped member.

Further, the opening / closing device to which the opening / closing body mounting method of the present invention can be applied may be such that the moving direction of the opening / closing body is any of the vertical direction, the horizontal direction, the horizontal direction, the diagonal direction and the like.
