Description

  The present invention relates to a sealing material that closes a gap such as a large shutter or door.

  In general, an opening that is an entrance of a warehouse or a factory is provided with a shutter that can open and close the opening. In this case, since the shutter must be moved when opening and closing, it is necessary to provide a slight gap between the shutter and the opening. However, if a gap is provided between the shutter and the opening, dust, insects, and the like enter through this gap even when the shutter is closed.

  Therefore, conventionally, a configuration has been proposed in which the gap between the shutter and the opening is closed with a brush portion (seal material) to prevent entry of dust, insects, and the like (for example, Patent Document 1). reference). In the configuration of Patent Document 1, a brush portion including a plurality of bristles and a bundling portion that bundles the base ends of the plurality of bristles is disposed so as to close a gap between the shutter and the opening.

  By the way, when the opening described above is large, it is necessary to enlarge the shutter in accordance with the opening. When the shutter is made larger, the gap between the shutter and the opening becomes longer. Therefore, the length of the brush portion needs to be increased in accordance with the length of the gap.

JP 2004-156239 A

  However, if the length of the brush part of Patent Document 1 is increased, the bundling part is made of metal and cannot be bent, so that there is a problem that it takes up space during storage or transportation.

  The present invention has been made paying attention to such problems existing in the prior art. The object is to provide a sealing material that can save space even when lengthened.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.

  According to this structure, since the sealing material can be folded at the portion between the base materials in the fluff portion, it can be folded small. For this reason, it becomes possible not to take a place even if it lengthens a sealing material.

In the sealing material, it is preferable that the plurality of base materials are arranged at equal intervals.
According to this configuration, for example, when the sealing material is folded at a portion between the base materials in the fluff portion and folded in a zigzag manner, both end portions that become folds of the sealing material can be aligned. Therefore, it becomes possible to fold the sealing material neatly.

  The sealing material further includes an attachment member that is detachably attached to one end side of the fluff portion between the plurality of base materials, and the attachment member is attached to one end side of the fluff portion In the above, it is preferable to sandwich one end side of the fluff portion.

  According to this configuration, by attaching the attachment member to one end side of the fluff portion, the difference between the state of the portion corresponding to between the base materials in the fluff portion and the state of the portion corresponding to the base material in the fluff portion is determined. Can be small. Therefore, it becomes possible to make the state of the whole fluff part substantially uniform.

  The sealing material further includes a plurality of support members attached to the plurality of base materials, and the support member is formed integrally with the support portion and a support portion that slidably supports the base material, It is preferable to provide an attachment portion that can be attached to the attachment portion.

Hereinafter, one embodiment of a sealing material is described based on a drawing.
As shown in FIG. 1, the sealing material 11 is detachably attached to the brush unit 12, a long belt-like brush unit 12, a plurality (five in the present embodiment) support members 13 attached to the brush unit 12, and the brush unit 12. And a plurality of (four in this embodiment) attachment members 14 are attached.

  As shown in FIG. 2, the brush unit 12 includes a band-shaped fluff portion 15 and a plurality (five in the present embodiment) of base materials 16 joined to one end side in the short direction of the fluff portion 15. Yes. The base material 16 is made of a hard synthetic resin and is formed by extrusion molding.

  The base material 16 has a band-like shape that connects a pair of sandwiching pieces 16a joined to the fluff part 15 in a state where one end side in the short direction of the fluff part 15 is sandwiched, and base ends of the pair of sandwiching pieces 16a. Connecting portion 16b. Therefore, the base material 16 is substantially U-shaped when viewed from the longitudinal direction.

  As shown in FIG. 3, the fluff portion 15 has at least one or more of the yarns 17 made of synthetic resin multifilaments knitted in a meandering manner and the curved portions on both sides extend in parallel to each other (this embodiment). Then, two are formed by holding the synthetic resin holding yarns 18 and then cutting the central portion (cut along the arrows in FIG. 3).

  In other words, the fluff portion 15 has the base end portions (curved portion side; one end side in the short direction of the fluff portion 15) of the plurality of U-shaped yarns 17 arranged in parallel with each other. It is formed by holding together by two holding yarns 18 that extend straight and parallel to each other along the parallel direction. Therefore, the short direction in the fluff portion 15 is the direction in which the plurality of yarns 17 extend.

  And when joining the fluff part 15 and the five base materials 16 and forming the brush unit 12, as shown in FIG. 4, the base end side (holding yarn 18 side; short direction) of the fluff part 15 is shown. One end side) is inserted between the pair of sandwiching pieces 16a of the five base materials 16 respectively. As a result, the two holding yarns 18 are clamped by the pair of clamping pieces 16 a of the five base materials 16 together with the base end portions of the plurality of yarns 17 of the fluff portion 15.

  At this time, the five base materials 16 are respectively arranged at equal intervals in the longitudinal direction of the fluff portion 15 (the parallel direction of the plurality of yarns 17 constituting the fluff portion 15). Thereafter, as shown in FIG. 2, the brush unit 12 is obtained by sewing and joining the pair of sandwiching pieces 16 a of the five base materials 16 and the base end side of the fluff portion 15 with the sewing thread 19.

  As shown in FIGS. 1 and 5, the support member 13 is made of a metal such as aluminum, and the length in the longitudinal direction is set to the same length as the base material 16. The support member 13 is attached to the base material 16 of the brush unit 12 to support the base material 16, and is formed integrally with the support portion 21, and a support frame 32 (example of an attached portion described later). And an attaching portion 22 that can be attached to the housing (see FIG. 11).

  The support portion 21 includes a pair of side walls 21a that sandwich the base material 16 and a band-shaped bottom wall 21b that connects the base ends of the pair of side walls 21a. The tip portions of the pair of side walls 21a are inclined inward. Therefore, the support portion 21 has a substantially U shape when viewed from the longitudinal direction.

  In this case, the base material 16 is accommodated in the support portion 21 so as to be slidable along the longitudinal direction and not slidable in a direction intersecting the longitudinal direction. The attachment portion 22 has a belt shape and extends from one end portion in the short direction on the outer surface of the bottom wall 21b of the support portion 21 so as to form an acute angle (an angle of 45 degrees in this embodiment) with the bottom wall 21b.

  As shown in FIGS. 1 and 6, the attachment member 14 is made of synthetic resin, and is detachably attached to one end side (holding yarn 18 side) of the fluff portion 15 between the five base materials 16. . That is, the four attachment members 14 are arranged on one end side of the fluff portion 15 so as to fill four gaps between the five base materials 16 sewn by the sewing thread 19 on one end side of the fluff portion 15. Each can be detachably attached.

  The attachment member 14 has a pair of flat plate-like holding portions 14a that hold one end side of the fluff portion 15 in a state of being attached to one end side of the fluff portion 15, and a flat plate shape that connects the base ends of the pair of holding portions 14a. Connecting portion 14b. A pair of clamping part 14a inclines inside. The distance between the tip portions of the pair of sandwiching portions 14 a is slightly narrower than the thickness of one end side (holding yarn 18) of the fluff portion 15.

  When the attachment member 14 is attached to one end side of the fluff portion 15, the attachment member 14 is connected to one end of the fluff portion 15 in a state where one end side of the fluff portion 15 is placed between the tip portions of the pair of sandwiching portions 14 a. Press toward the side. Then, the pair of sandwiching portions 14a is elastically deformed so that the distance between the tip portions of the pair of sandwiching portions 14a is widened, and one end side of the fluff portion 15 is inserted between the pair of sandwiching portions 14a.

  Thereafter, the pair of sandwiched portions 14a that have been elastically deformed tries to return to the original shape by their own elastic restoring force, so that one end side of the fluff portion 15 is pinched by the pair of sandwiched portions 14a. The attachment work of the attachment member 14 to one end side of 15 is completed. In addition, what is necessary is just to pull out the attachment member 14 from the one end side of the fluff part 15 when removing the attachment member 14 attached to the one end side of the fluff part 15.

Next, the operation when the sealing material 11 is transported by truck or stored in a warehouse will be described.
When the sealing material 11 is transported by truck or stored in a warehouse, the sealing material 11 is folded so that the sealing material 11 does not take up space. When the sealing material 11 is folded, first, as shown in FIG. 7, each support member 13 is slid to a position where it does not overlap with each attachment member 14. That is, each support member 13 is slid to a position completely overlapping with each base material 16. Subsequently, each attachment member 14 is removed.

  Subsequently, as shown in FIG. 8, the sealing material 11 is folded in a zigzag manner (a zigzag fold) with a portion between the base materials 16 in the fluff portion 15 (a portion where the attachment member 14 is attached) as a fold. At this time, since the fluff part 15 has flexibility, it is easily bent. Furthermore, since each base material 16 (each support member 13) is the same length at this time, it is piled up cleanly so that both ends may be aligned.

  Therefore, since the length of the sealing material 11 can be reduced to a small length by reducing the length of the base material to about 16 minutes, it does not take up space when transported by truck or stored in a warehouse. can do.

  Incidentally, when the length of the sealing material 11 is particularly long (when the length of the sealing material 11 is 6 m or more, for example), if the sealing material 11 cannot be folded, it is placed on a truck bed or stored in a warehouse. In some cases, it takes up a lot of space, making it extremely difficult to put on a truck bed or store in a warehouse.

Next, the effect | action at the time of using the sealing material 11 is demonstrated.
Now, as shown in FIG. 10, the sealing material 11 is used by being attached to a large shutter device 30 having a height of, for example, 6 m or more. The shutter device 30 includes a pair of support frames 32 erected in parallel on a floor surface 31 at a predetermined distance, a housing 33 installed between upper ends of the pair of support frames 32, and the housing 33 and the floor surface. And a shutter 34 disposed in a space surrounded by a pair of support frames 32.

  The shutter 34 is composed of a plurality of blade plates 35 extending in a direction perpendicular to the vertical direction (vertical direction). The shutter 34 has a configuration in which the blade blades 35 adjacent to each other in the vertical direction are connected to each other so as to be rotatable, and a configuration in which the shutter 34 is expanded in a flat shape as shown in FIG. It is configured to be able to take.

  The housing 33 is formed in a bottomed rectangular box shape having an open bottom, and a cylindrical drum (not shown) is rotatably supported therein. The upper end of the shutter 34 is connected to the outer peripheral surface of the drum (not shown).

  The shutter device 30 rotates the drum (not shown) in the forward direction in the housing 33 and winds the shutter 34 on the outer peripheral surface of the drum, whereby the shutter 34 is accommodated in the housing 33. It is said. On the other hand, the shutter device 30 rotates the drum (not shown) in the reverse direction in the opened state, unwinds the shutter 34 from the outer peripheral surface of the drum, and feeds the shutter 34 downward from the inside of the housing 33. The shutter 34 is developed between the floor 31 and the closed surface.

  As shown in FIG. 11, the pair of support frames 32 are formed of a metal in a rectangular column shape, and guide grooves 36 extending along the longitudinal direction of the pair of support frames 32 are respectively formed on the inner surfaces 32 a facing each other. Is formed. Both side portions 34a of the shutter 34 are inserted into the guide grooves 36 of the pair of support frames 32, respectively.

  The shutter 34 is restricted from moving in the direction intersecting the vertical direction by the guide grooves 36 of the pair of support frames 32 when performing an opening / closing operation for opening or closing the shutter device 30. It is designed to reciprocate up and down in the state. A gap S is formed between the shutter 34 and the guide groove 36 of the pair of support frames 32.

  The sealing material 11 is used by being attached to the shutter device 30 so as to close these gaps S. When attaching the sealing material 11 to the shutter device 30, as shown in FIG. 9, the respective supporting members 13 are slid so as to close the gaps between the respective supporting members 13 with the respective attaching members 14 being attached. After that, the sealing material 11 is cut according to the height (length) of the gap S (see FIG. 11).

  Subsequently, as shown in FIGS. 10 and 11, the sealing material 11 is applied to the inner side surfaces 32 a of the pair of support frames 32 so as to close the gap S between the corner portions formed by the shutter 34 and the pair of support frames 32. Install each. In this case, the seal member 11 is fixed to the inner surface 32a of the support frame 32 by screws (not shown) so that the tip of the fluff 15 is in sliding contact with the shutter 34. At this time, since the attachment portion 22 forms an angle of 45 degrees with respect to the bottom wall 21b, the tip portion of the fluff portion 15 is in sliding contact with the shutter 34 at an angle of 45 degrees.

  And in the state which closed the shutter 34, since the clearance gap S is blocked | closed by the sealing material 11, entry of dust, an insect, etc. from the clearance gap S can be suppressed. Further, since the tip end portion of the fluff portion 15 is in sliding contact with the shutter 34 at an oblique angle of 45 degrees, the shutter 34 is compared with the case where the tip end portion of the fluff portion 15 is in sliding contact with the shutter 34 perpendicularly. The sliding resistance between the fluff portion 15 and the shutter 34 at the time of opening and closing can be reduced.

According to the embodiment detailed above, the following effects are exhibited.
(1) Since the base material 16 is arrange | positioned at intervals, the sealing material can be bent in the part between the base materials 16 in the fluff part 15. FIG. For this reason, the sealing material 11 can be made small by folding the part between the base materials 16 in the fluff part 15 into a zigzag with a crease. Therefore, even if the sealing material 11 is lengthened, it is possible to save space.

  (2) Since the sealing material 11 is arranged so that the plurality of base materials 16 are equally spaced, the sealing material is folded when zigzag is folded at a portion between the base materials 16 in the fluff portion 15. It is possible to align both end portions that become eleven folds. Therefore, the sealing material 11 can be folded neatly.

  (3) The sealing material 11 includes an attachment member 14 that is detachably attached to one end side of the fluff portion 15 between the base materials 16, and the attachment member 14 is attached to one end side of the fluff portion 15. One end side of the fuzz portion 15 is clamped. For this reason, by attaching the attachment member 14 to the one end side of the fluff part 15, the state of the part corresponding to between the base materials 16 in the fluff part 15, and the state of the part corresponding to the base material 16 in the fluff part 15 Can be reduced. Therefore, the state of the entire fluff portion 15 can be made substantially uniform. Incidentally, if the attachment member 14 is not attached to one end side of the fluff portion 15, the portion of the yarn 17 corresponding to the space between the base materials 16 in the fluff portion 15 is the portion of the yarn corresponding to the base material 16 in the fluff portion 15. Since it becomes difficult to hold | maintain in the same position compared with 17, it will become easy to make a clearance gap in the part corresponding to between the base materials 16 in the fluff part 15. FIG.

  (4) The sealing material 11 includes a plurality of support members 13 that are respectively attached to the plurality of base materials 16, and the support member 13 is formed integrally with the support portion 21 that supports the base material 16 slidably. And an attachment portion 22 that can be attached to the support frame 32. For this reason, the sealing material 11 can be easily attached to the support frame 32.
