Description

[Technical Field]

[0001] The present invention relates to a portable partition. [Background technology]

[0002] Patent Document 1 below shows a soundproof and dustproof structure using a panel unit formed by adhering a flexible tube to a flexible sheet.

[0003] This soundproof and dustproof structure has three vertically extending columns and three horizontal bars that support the columns. Air is blown into these columns and horizontal bars to form them into a cylindrical shape. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-30046 Summary of the Invention [Problem to be solved by the invention]

[0005] In the soundproof and dustproof structure of Patent Document 1, the pillars and cross bars are formed in a frame shape. When the pillars and cross bars are formed in such a frame shape, it is difficult to adjust the height and width of the panel unit.

[0006] For example, the above-mentioned Patent Document 1 describes tying the middle of the pillars with string when shortening the height of a panel unit. However, this can cause the cross bars where air is not blown and the flexible sheet attached to these cross bars and pillars to become loose, making it difficult to ensure airtightness. In other words, it is difficult to adjust the height and width while ensuring airtightness.

[0007] In consideration of the above, the present invention aims to provide a portable partition whose height and width can be adjusted while ensuring airtightness. [Means for solving the problem]

[0008] The portable partition of claim 1 comprises at least two pillar members formed of a flexible membrane body filled with air inside, a beam member formed of a flexible membrane body whose interior is connected to the interior of the pillar members and whose one end is connected to the upper end of one of the pillar members and whose other end is cantilevered and protrudes laterally beyond the upper end of the other pillar member, and a sheet that is detachably joined to the pillar members and beam members along the longitudinal direction and can suppress the scattering of dust.

[0009] The portable partition of claim 1 is formed from pillar members, beam members, and a sheet of a membrane body. The pillar members and beam members are formed by filling the interior with air. Therefore, it is lighter and easier to carry than a partition formed by attaching a sheet to steel scaffolding, etc. Also, by adjusting the air pressure, it can be held in tension between the ceiling and floor, making it easy to install. Furthermore, it can be easily carried by letting the air out.

[0010] The height of the entire partition can be adjusted by rolling up the lower end of the column member and filling it with air.Furthermore, since the other end of the beam member protrudes laterally from the column member as a cantilever, the width of the entire partition can be adjusted by rolling up this end and filling it with air.

[0011] In addition, the sheet is detachably joined to the column members and the beam members in the longitudinal direction. Therefore, if the sheet is not joined, it is easier to wrap around the lower end of a pillar member or the end of a beam member than when the sheet is joined. Also, since the sheet that is not rolled up can be placed along the floor or wall surface, it is easier to ensure airtightness.

[0012] The portable partition of claim 2 is the portable partition of claim 1, wherein a holding member that can hold the pole member in a folded state can be attached to the lower end of the pole member.

[0013] In the portable partition of claim 2, the lower ends of the pillar members can be held in a folded state, which makes it easy to adjust the height of the entire partition.

[0014] The portable partition of claim 3 is the portable partition of claim 1 or 2, wherein one end edge of the sheet that runs along the pillar member has a fastener formed thereon that can be joined to the other end edge that runs along the pillar member.

[0015] In the portable partition of claim 3, the fasteners can be joined together to allow the portable partitions to be connected and placed together.

[0016] The portable partition of claim 4 is the portable partition of claim 1, wherein the lower ends of the pillar members are folded inward so that the inner surfaces of the pillar members come into contact with each other, and can be inserted into a holding member formed in a cylindrical shape with a bottom.

[0017] In the portable partition of claim 4, the lower end of the pole member can be inserted into the cylindrical, bottomed holding member while being folded inward so that the inner circumferential surfaces of the pole member are in contact with each other. This allows the length of the pole member to be shortened.

[0018] In this case, compared to when the lower end is folded to shorten the pole member, it is easier to maintain the outer shape of the lower end of the pole member similar to the outer shape of the rest of the pole member, making it easier to insert the pole member into the holding member.

[0019] The portable partition of claim 5 is the portable partition of claim 4, wherein a hook-and-loop fastener is fixed in the vertical direction to the outer peripheral surface of the lower end of the pillar member, and a hook-and-loop fastener that is detachable from the hook-and-loop fastener is fixed in the circumferential direction to the inner peripheral surface of the holding member.

[0020] In the portable partition of claim 5, the hook-and-loop fasteners are fixed in the vertical direction to the outer peripheral surfaces of the lower ends of the pole members, so that even when the lower ends of the pole members are folded inward, the hook-and-loop fasteners tend to remain exposed on the outer peripheral surfaces of the pole members.

[0021] On the other hand, a hook-and-loop fastener is fixed to the inner peripheral surface of the holding member along the circumferential direction, so that it intersects with the hook-and-loop fastener fixed to the outer peripheral surface of the pillar member, making it easy to fix the pillar member and the holding member together.

[0022] A portable partition according to a sixth aspect of the present invention is the portable partition according to the fourth or fifth aspect of the present invention, wherein an air jack capable of lifting the pillar member is attached to the bottom of the holding member.

[0023] In the portable partition of claim 6, an air jack capable of lifting the pole member is attached to the bottom of the holding member. This allows the height of the pole to be adjusted. In other words, the height of the pole member can be adjusted while the pole member is inserted into the holding member, without having to remove the pole member from the cap material and adjust the folding length of the bottom end of the pole member. [Effects of the Invention]

[0024] The portable partition of the present invention allows adjustment of height and width while ensuring airtightness. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0026] A portable partition according to an embodiment of the present invention will be described below with reference to the drawings. Components indicated with the same reference numerals in the various drawings are the same components. However, unless otherwise specified in the specification, each component is not limited to one, and may be present in multiple numbers.

[0027] Furthermore, the description of the same components and symbols in each drawing may be omitted. Note that the present invention is not limited to the following embodiments, and may be implemented by making appropriate modifications, such as omitting components or replacing them with different components, within the scope of the object of the present invention.

[0028] In each figure, the directions indicated by arrows X and Y are directions along the horizontal plane and are perpendicular to each other. The direction indicated by arrow Z is a direction along the vertical direction (up and down). In each figure, the directions indicated by arrows X, Y, and Z are assumed to be consistent with each other.

[0029] <Portable partition> FIG. 1 shows a portable partition (hereinafter referred to as "partition") 10 according to an embodiment of the present invention. The partition 10 is a protective wall for preventing dust from scattering over a wide area during demolition work, such as building demolition. The partition 10 can also be used to prevent paint from scattering during painting work, etc. The partition 10 is formed using a sheet 20 and an air body 30.

[0030] (sheet) 2, the sheet 20 is formed in a rectangular shape with a width W1 (for example, W1 = 3810 [mm]) and a height H1 (for example, H1 = 3310 [mm]). The sheet 20 is made of, for example, PVC, and is a film that can suppress the scattering of dust, and weighs approximately 5 [kg].

[0031] Fasteners G (fasteners G1, G2, G3) are fixed to both sides of the sheet 20. The fasteners G are joining materials used to bond hook-shaped raised hook fasteners and loop-shaped raised hook fasteners together. These hook fasteners can be detachably bonded together.

[0032] In the following description, the hook-raised hook-and-loop raised hook-and-loop fasteners will not be specified as to their types, but will be referred to as fasteners G1, G2, G3, .... Furthermore, these fasteners G1, G2, G3, ... may be collectively referred to as fastener G.

[0033] The fasteners G bonded to each other are each a hook-and-loop fastener with raised hooks and a loop-and-loop fastener with raised loops. In the following description, the pair of fasteners bonded to each other may be simply referred to as fastener G.

[0034] On one side of the sheet 20 (the far side of the paper in FIG. 2), a zipper G1 is fixed along the vertical direction to one end edge 20E1 in the width direction of the sheet 20. Also, on the other side of the sheet 20 (the near side of the paper in FIG. 2), a zipper G2 is fixed along the vertical direction to the other end edge 20E2 in the width direction.

[0035] In addition, in a state where the air body 30 is joined to the sheet 20, the fasteners G1 and G2 are arranged in a direction along a pillar member 32 (see FIG. 1) described later.

[0036] A fastener G3 is fixed to the other surface of the sheet 20. The fastener G3 is a hook-and-loop fastener that can be bonded to a fastener G4 (see FIG. 3, etc.) of the air body 30, which will be described later.

[0037] The fasteners G1, G2, and G3 are arranged such that their lower ends are spaced a width H2 (e.g., H2 = 300 mm) from the lower end of the sheet 20. The upper end of the fastener G3 is spaced a width H3 (e.g., H3 = 100 mm) from the upper end of the sheet 20.

[0038] (Air body) As shown in Figure 3, the air body 30 is a bag-like structure formed of a flexible membrane filled with air. The air body 30 includes pillar members 32, beam members 34, and connecting reinforcement members 36. These pillar members 32, beam members 34, and connecting reinforcement members 36 are connected in a mutually communicating state as shown below, allowing air to pass through. The weight of the air body 30 is approximately 7 kg.

[0039] As the flexible material for forming the air body 30, various materials can be used, such as tarpaulin, PVC (polyvinyl chloride), PP (polypropylene), CSM (chlorosulfonated polyethylene), etc., in which both or one side of a fiber base material such as knitted fabric, woven fabric, or nonwoven fabric made of polyester or the like is coated with polyvinyl chloride, rubber, etc.

[0040] The pillar member 32 is a long member formed in a cylindrical (columnar) shape with a diameter of approximately 180 mm, and two pillar members are provided in the air body 30 of this embodiment. The pillar members 32 have a height H4 (for example, H4 = 3000 mm).

[0041] The height H4 is the dimension when the pressure of the air filled inside the air body 30 is equal to atmospheric pressure when no external force is applied. The height H4 is also the dimension when the membrane forming the air body 30 is not elastically deformed. The same applies to the various dimensions of the air body 30 described below.

[0042] A handle 32E is formed on each pillar member 32. The handle 32E is provided at a height H5 (for example, H5 = 1500 [mm]) from the lower end of the pillar member 32. The handles 32E are provided on opposing portions of adjacent pillar members 32. These handles 32E are arranged at an interval W3 (for example, W3 = 1500 [mm]) from each other.

[0043] The beam member 34 is a long member formed in a cylindrical (columnar) shape with a diameter of approximately 180 mm, and one end 34A is connected to the upper end of one (right side in FIG. 3) pillar member 32. The other end 34B is cantilevered and protrudes laterally from the upper end of the other (left side in FIG. 3) pillar member 32. The beam member 34 has a length W2 (for example, W2 = 3600 mm).

[0044] The pillar members 32 are joined to the ends of the beam members 34 and to the longitudinal center of the beam members 34. The number of pillar members 32 can be increased as appropriate when the length W2 of the beam members 34 is long. The pillar members 32 may be provided at intervals of approximately 1800 mm or less in the longitudinal direction of the beam members 34.

[0045] The connecting reinforcement member 36 is a long member formed in a tubular (cylindrical) shape, and both ends are connected to the pillar member 32. The connecting reinforcement member 36 is provided so that its lower end is located at a height H6 (for example, H6 = 1000 [mm]) from the lower end of the pillar member 32.

[0046] A valve 36A is provided in the connecting reinforcement member 36. By introducing air into the inside of the connecting reinforcement member 36 from the valve 36A, the connecting reinforcement member 36, the column members 32, and the beam members 34 are filled with air.

[0047] (Connecting structure between air body and seat) Fasteners G4 are fixed to the column members 32, beam members 34, and connecting reinforcement members 36 along their respective axial directions. The partition 10 shown in Fig. 1 is formed by attaching the fasteners G4 to fasteners G3 of the sheet 20 shown in Fig. 2. The sheet 20 can be attached and detached along the longitudinal direction of the column members 32 and beam members 34 by attaching and peeling off the fasteners G3 and G4.

[0048] When arranging a plurality of partitions 10 in the horizontal direction (X direction), the end edge 20E1 of a sheet 20 and the end edge 20E2 of the adjacent sheet 20 are attached together using fasteners G1 and G2.

[0049] As a result, multiple partitions 10 are connected in the horizontal direction as shown in Fig. 4. In each figure, the fasteners G1 and G2 in the bonded state and the fasteners G3 and G4 in the bonded state are shown as fasteners G.

[0050] As shown in this figure, when the partitions 10 are connected laterally, the air bodies 30 in each partition 10 are arranged spaced apart from each other. Specifically, in the air bodies 30 arranged adjacent to each other, a gap V is formed between the beam member 34 of one air body 30 (the right side in FIG. 4) and the beam member 34 of the other air body 30 (in other words, the upper end of the pillar member 32).

[0051] By forming this gap V, even if the beam members 34 of the partition 10 are arranged in a direction that intersects with each other in a planar view, as shown in Figures 5(A) and (B), interference between the beam members 34 is suppressed, making it easy to arrange the beam members 34 at any angle.

[0052] (holding member) The air body 30 can be used by inserting the lower end of the column member 32 and the cantilever end of the beam member 34 into a holding member 40 shown in FIG. 3(A).

[0053] 3(A) and 3(C), fasteners G5 are fixed to the lower end of the column member 32 and the cantilever end of the beam member 34. The fasteners G5 are fixed to three surfaces of the column member 32 and the beam member 34: the surface opposite to the surface to which the fastener G4 is fixed, and two surfaces that intersect the surface to which the fastener G4 is fixed at approximately 90°.

[0054] On the other hand, a fastener G6 is fixed to the inner circumferential surface of a cap-shaped holding member 40 formed in a cylindrical shape with a bottom. The fastener G6 is fixed along the circumferential direction of the inner circumferential surface of the holding member.

[0055] For example, the lower end of the pillar member 32 is inserted into the holding member 40 in a folded state or in a rolled state along the axial direction of the pillar member 32. This causes the fasteners G4 and G5 to be bonded to the fastener G6. This allows the pillar member 32 to be held in a folded or rolled state.

[0056] Similarly, for example, the cantilever end of the beam member 34 is inserted into the holding member 40 in a folded state or in a state where it is wound along the axial direction of the beam member 34. This causes the fasteners G4 and G5 to be bonded to the fastener G6. As a result, the beam member 34 is held in a folded or wound state.

[0057] In this way, by holding the column members 32 and the beam members 34 in a folded or rolled state, the column members 32 and the beam members 34 can be joined to the sheet 20 in a state where they are shortened to any length, as shown in Figure 6.

[0058] 3(A), the fastener G5 of the column member 32 is formed from the lower end of the column member 32 to the lower end of the connecting reinforcement member 36. The fastener G5 of the beam member 34 can be formed to any position within the range from the cantilever end of the beam member 34 to the joint of the column member 32. The column member 32 and the beam member 34 can be folded to any length within the range where the fastener G5 is formed, and inserted into the holding member 40 for use.

[0059] <Action and effect> The partition 10 according to the embodiment of the present invention is formed of an air body 30 including pillar members 32 and beam members 34 of a membrane body, and a sheet 20. The pillar members 32 and beam members 34 are formed with air filled inside.

[0060] This makes it lighter and easier to carry than partitions made by attaching sheets to steel scaffolding, etc. Furthermore, by adjusting the air pressure, it can be tensioned and held between the floor and ceiling, making it easy to install.

[0061] For example, in the state shown in Figure 7(A), the height H7 from the floor to the ceiling of the building in which the partition 10 is installed is set to be equal to or less than the height H4 (see Figure 3) of the pillar member 32. As a result, when the air body 30 is filled with air, the pillar member 32 is held in a tensioned state between the floor and the ceiling.

[0062] In this state, the sheet 20 can be easily held in place by sandwiching the lower end of the sheet 20 between the lower end of the pillar member 32 and the floor surface, and sandwiching the upper end of the sheet 20 between the beam member 34 and the ceiling.

[0063] 7(B), the lower and upper ends of the sheet 20 may not be sandwiched between the lower ends of the pillar members 32 and the floor surface, and between the beam members 34 and the ceiling. In this case, it is preferable to place a weight WT or the like at the lower end of the sheet 20 to prevent it from curling up.

[0064] Furthermore, as shown in Figure 7(C), the height of the entire partition 10 can be adjusted by bending or rolling up the lower end of the pillar member 32, and then holding the folded or rolled up state with the holding member 40 and filling it with air.

[0065] Furthermore, by releasing the air from the air body 30, the tension between the floor and ceiling is released, allowing for easy removal. Furthermore, no restoration work is required after removal. In contrast, for example, in partitions formed by attaching a sheet to the floor or ceiling with adhesive tape, the adhesive tape may need to be removed.

[0066] Furthermore, as shown in Figure 3, the air body 30 is cantilevered with the end 34B of the beam member 34 protruding laterally from the column member 32. This allows this end 34B to be folded or rolled up. Then, as shown in Figure 6, by holding the folded or rolled up state with the holding member 40 and filling it with air, the overall width of the partition can be adjusted.

[0067] Furthermore, the sheet 20 is joined to the air body 30 using fasteners G. Therefore, the sheet 20 is detachably joined to the pillar members 32 and the beam members 34 along the longitudinal direction.

[0068] As a result, if the sheet 20 is not joined, it is easier to roll the lower end of the column member 32 or the end of the beam member 34 than if the sheet 20 is joined. Also, the unrolled sheet 20 can be placed along the floor or wall of a building, making it easier to ensure airtightness.

[0069] <Other embodiments> In the above embodiment, the fasteners G1 and G2 fixed to the edge of the sheet 20 are formed by hook-and-loop fasteners, but the present invention is not limited to this. For example, these fasteners G1 and G2 may be formed by using shippers. Furthermore, when the partition 10 is used alone, these fasteners G1 and G2 may be omitted.

[0070] In addition, in the above embodiment, as shown in Figures 4 and 5, when air bodies 30 are arranged adjacent to each other, a gap V is provided between the beam member 34 of one air body 30 and the beam member 34 of the other air body 30.

[0071] However, in an embodiment of the present invention, it is not necessary to provide this gap V. For example, as shown in Figure 8(A), the beam member 34 of one air body 30 and the beam member 34 of the other air body 30 may be arranged so that they come into contact with each other. When arranged in this manner, a gap is less likely to occur between the beam member 34 and the ceiling.

[0072] Furthermore, regardless of whether or not a gap V is provided between the beam member 34 of one air body 30 and the beam member 34 of the other air body 30, these beam members 34 may be connected to each other using a connecting member 38, as shown in FIG. 8(B). By using such a connecting member 38, it is possible to prevent the beam member 34 from bending. The bending of the beam member 34 may also be prevented by placing a tension rod between the beam member 34 and the floor. It is preferable to use a hollow pillar member filled with air, like the air body 30, as the tension rod.

[0073] The connecting member 38 is formed using, for example, a hook-and-loop fastener. In this case, the connecting member 38 is attached to the fastener G5 of one beam member 34 and the fastener G7 of the other beam member 34. The fastener G7 is a hook-and-loop fastener provided for attaching the connecting member 38, and is fixed to the upper surface of the end of the beam member 34 joined to the column member 32.

[0074] By providing such a connecting member 38, the end of the cantilevered beam member 34 is fixed, thereby preventing the beam member 34 from sagging due to its own weight. This improves the airtightness of the partition 10.

[0075] In the above embodiment, as shown in FIG. 2, only the fastener G1 extending in the vertical direction is fixed to one surface of the sheet 20 (the rear side of the paper in FIG. 2), but the embodiment of the present invention is not limited to this.

[0076] For example, as shown in Figure 9, in order to connect and use partitions 10 with the length of beam member 34 shortened using retaining member 40, a fastener G8 that holds sheet 20 in a folded state may be formed on the surface of sheet 20 to which fastener G1 is fixed.

[0077] In addition, in FIG. 9, the fastener G8 is illustrated in a state in which a hook-shaped raised surface fastener and a loop-shaped raised surface fastener are combined.

[0078] In the above embodiment, as shown in Fig. 3, the fastener G4 is fixed to only one surface of the column member 32 and the beam member 34 (the surface on the far side of the paper in Fig. 3), but the embodiment of the present invention is not limited to this. For example, the fastener G4 may also be fixed to the other surface of the column member 32 and the beam member 34 (the surface on the near side of the paper in Fig. 3).

[0079] As a result, as shown in Figure 10(A), the air body 30 can be used in a state where its orientation is inverted horizontally from the state shown in Figure 1. By connecting the partition 10 shown in Figure 10(A) and the partition 10 shown in Figure 1 laterally via fasteners G1 and G2, it is possible to ensure wide spacing between the pillar members 32. This makes it easy to form, for example, an entrance or exit for work.

[0080] In addition, in the above embodiment, as shown in FIG. 3, a cylindrically shaped holding member 40 is used as a holding member for holding the column member 32 and the beam member 34 in a folded or rolled state, but the embodiment of the present invention is not limited to this.

[0081] As the holding member, for example, a belt 50 shown in Figures 11(A) to 11(D) can be used instead of or in addition to the holding member 40. As shown in Figure 11(A), the belt 50 is fixed to the lower end of at least one of the pillar member 32 and the beam member 34, for example.

[0082] 11(B) and (C), the pillar member 32 or the beam member 34 is wound up with both ends of the belt 50 protruding from the pillar member 32 or the beam member 34. Then, as shown in FIG. 11(D), when the desired length of the pillar member 32 or the beam member 34 is obtained, both ends of the belt 50 are fastened together with the buckle 52.

[0083] In this way, the fastener G5 is not necessary if the belt 50 is used. Furthermore, when the pillar member 32 and the beam member 34 are held in a wound state using the belt 50, the holding member 40 may be omitted.

[0084] Omitting the retaining member 40 reduces the amount of material used to form the partition 10. On the other hand, using the retaining member 40 adjusts the shape of the ends of the column members 32 and beam members 34 in the rolled state, thereby increasing the stability of the partition 10 when installed.

[0085] Thus, in the present invention, the holding member that holds the column member 32 and the beam member 34 in a folded or rolled state includes an embodiment that uses only the holding member 40 formed in a cylindrical shape with a bottom, an embodiment that uses only the belt 50 "instead of" the holding member 40, and an embodiment that uses the belt 50 "in addition to" the holding member 40.

[0086] In addition, in the present invention, as shown in Figures 12(A) to (C), the lower ends of the pillar members 32 can be inserted into the holding member 40 in a state where they are folded inward so that the inner surfaces of the pillar members 32 come into contact with each other.

[0087] As shown in Figure 12(A), the lower end of the pillar member 32 is closed to prevent air from leaking out of the air body 30. Therefore, as shown in Figure 12(B), by folding this closed lower end into the interior of the pillar member 32, the length of the pillar member 32 can be changed while preventing air from leaking out. Note that folding changes the amount of air that can be filled into the air body 30, so it is preferable to perform the folding before the air body 30 is completely filled with air.

[0088] Then, as shown in FIG. 12(C), by folding the pillar members 32 inward so that their inner peripheral surfaces come into contact with each other, and then inserting the lower ends of the pillar members 32 into the holding member 40, the pillar members 32 can be kept in a shortened state.

[0089] In this way, by folding the lower end of the pillar member 32 inward, it is easier to maintain the outer shape of the lower end of the pillar member 32 similar to the outer shape of the rest of the pillar member 32, compared to when the tip is folded, for example, in an accordion-like shape to shorten the pillar member 32.

[0090] This makes it easier to insert the lower end of the pillar member 32 into the holding member 40. Also, compared to the case where the belt 50 shown in Fig. 11 is used, it is easier to adjust the length of the pillar member 32. Note that this embodiment in which the length is adjusted by folding the tip inward may also be applied to the beam member 34.

[0091] 3, multiple fasteners G5 formed using hook-and-loop fasteners are fixed in the vertical direction to the outer circumferential surface of the lower end of the pillar member 32. Therefore, even if the lower end of the pillar member 32 is folded inward as shown in FIG. 6, for example, the fasteners G5 tend to remain exposed to the outer circumferential surface of the pillar member 32.

[0092] Furthermore, fastener G6, which is a hook-and-loop fastener that is detachable from fastener G5, is fixed along the circumferential direction to the inner circumferential surface of holding member 40. Therefore, fastener G6 intersects with fastener G5 fixed to the outer circumferential surface of pillar member 32. This makes it easy to fix pillar member 32 and holding member 40 together.

[0093] 13(A) to 13(C), an air jack 60 capable of lifting the pillar member 32 may be attached to the bottom of the holding member 40. When using the air jack 60, the pillar member 32 is inserted into the holding member 40 with the air jack 60 not filled with air or not filled completely with air, as shown in FIG.

[0094] Then, the air body 30 is placed between the floor and the ceiling, and as shown in Figure 13(C), a compressor hose 62 or the like is connected to an air jack 60 and air is filled in. This causes the air body 30 to be held in a tensioned state between the floor and the ceiling.

[0095] In this way, the height of the pole member 32 can be adjusted by using the air jack 60. That is, the height of the pole member 32 can be adjusted while the pole member 32 remains inserted in the holding member 40, without having to remove the pole member 32 from the holding member 40 and then adjust the folded length or retracted length of the lower end of the pole member 32.

[0096] Regardless of whether the air jack 60 is used or not, the tip of the pillar member 32 can be inserted into the holding member 40 in any of the following states: folded in an accordion-like manner, rolled up as shown in Figures 11(B) to (D), or folded up as shown in Figures 12(B) and (C). Alternatively, the tip of the pillar member 32 may be inserted into the holding member 40 in a state where it is not folded, rolled up, or folded up as shown in Figure 11(A).

[0097] In addition, in each of the above-described embodiments, holding members for holding the column members 32 and the beam members 34 are provided, but the present invention is not limited to this. For example, the partition 10 may be configured without such holding members.

[0098] Even if the retaining member is omitted from the partition 10, when the air body 30 is filled with air, the pillar member 32 is held in a tensioned state between the floor and ceiling. Because the air body 30 is formed of a flexible membrane, even if the height H7 from the floor to the ceiling of the building in which the partition 10 is installed is greater than the height H4 of the pillar member 32, the pillar member 32 expands in the vertical direction and is held in a tensioned state between the floor and ceiling.

[0099] 14, a scale 70 may be formed on the tip of the column member 32. The scale 70 is a ruler that indicates the ceiling height. The method for forming the scale 70 is arbitrary, but the following method is one example.

[0100] 14, the ceiling height is H1, and the height of the holding member 40 is H3. In the column member 32, at the position where the upper end of the holding member 40 is located, that is, at the position where the distance from the ceiling surface is H2 (H2 = H1 - H3), "H1" is written together with a horizontal line indicating the scale 70.

[0101] This makes it possible to grasp the appropriate insertion depth when inserting the pillar member 32 into the holding member 40 after folding or retracting the tip of the pillar member 32. If the insertion depth is appropriate, the pillar member 32 and the holding member 40 are fixed by fasteners G5 and G6, so the height can be maintained. [Explanation of symbols]
