The air cleaning filter 21 is provided so as to capture organic solvent gas, fine dust, and the like contained in the air discharged from the inside of the working space to the outside through the upper opening 10A and the ceiling opening 20C.

[0024] The ceiling cover 20 is provided so that a side curtain 220 (described in detail later) for covering the multiple side openings 10B can be attached and detached. The ceiling cover 20 is provided so that, when the side curtain 220 is attached to the ceiling cover 20, the ceiling cover 20 and the side curtain 220 partition the above-mentioned work space from the space in which the object to be treated is placed.

[0025] In the following, more specific configuration examples of the frame 10 and the ceiling cover 20 will be described with reference to Figs. 1 to 5.

[0026] 1 and 2, the inner space surrounded by the frame 10 has, for example, a rectangular parallelepiped shape. A first direction X is the longitudinal direction of the inner space, and a second direction Y is the lateral direction of the inner space. The length of the inner space in the first direction X is longer than the length of the inner space in the second direction Y.

[0027] 1 and 2, the frame 10 includes, for example, four columns 11, four beams 12 detachably connected to the columns 11, and one central beam 12C. Each of the four columns 11 has an equivalent configuration to the others. The four beams 12 include two relatively long long beams 12A (girders) and two relatively short short beams 12B. The central beam 12C is detachably connected to the two long beams 12A.

[0028] As shown in Figs. 1 and 2, when the frame 10 is assembled, the columns 11 are arranged along the vertical direction Z and spaced apart from each other in the first direction X or the second direction Y. Each column 11 is connected to one long beam 12A and one short beam 12B. Each long beam 12A is arranged along the first direction X and spaced apart from each other in the second direction Y. Each short beam 12B is arranged along the second direction Y and spaced apart from each other in the first direction X. The central beam 12C is arranged along the second direction Y and is located between the two short beams 12B in the first direction X.

[0029] The frame 10 shown in Fig. 1 and Fig. 2 forms two upper openings 10A1, 10A2 and four side openings 10B1-10B4 in an assembled state. Each of the two upper openings 10A1, 10A2 is formed inside the two long beams 12A and the two short beams 12B. The two upper openings 10A1, 10A2 are arranged side by side in the first direction X with the central beam 12C in between. From a different perspective, each of the two long beams 12A, the two short beams 12B, and the central beam 12C constitutes the outer peripheral edge of each of the two upper openings 10A1, 10A2.

[0030] Each of the four side openings 10B1 to 10B4 is formed below each beam 12 between two columns 11 adjacent to each other in the first direction X or the second direction Y. From a different perspective, the two long beams 12A, the two short beams 12B, and the four columns 11 constitute the outer periphery of each of the four side openings 10B1 to 10B4. The four side openings 10B1 to 10B4 include a first set of side openings 10B1 and 10B2 that open in a first direction DR1 perpendicular to the vertical direction, and a second set of side openings 10B3 and 10B4 that open in a second direction DR2 perpendicular to both the vertical direction and the first direction DR1. The side openings 10B1 are provided as the above-mentioned work openings. The side openings 10B3 are provided as the above-mentioned air supply openings.

[0031] 1 and 2, an accommodation portion 11A for accommodating one end of the long beam 12A and an accommodation portion 11B for accommodating one end of the short beam 12B are formed at the upper end of each of the multiple columns 11. Each of the accommodation portions 11A and 11B is, for example, a tubular member fixed to the outer circumferential surface of each column 11. The central axis of each of the accommodation portions 11A and 11B is, for example, along the vertical direction Z. Each of the accommodation portions 11A and 11B formed in each column 11 is positioned relative to the column 11 so as to form a central angle of 90 degrees in the circumferential direction with respect to the central axis of the column 11.

[0032] 1 and 2, the frame 10 further includes, for example, a plurality of diagonal braces 13A and 13B. Each of the plurality of diagonal braces 13A is spanned between each of the plurality of columns 11 and each of the plurality of long beams 12A in an assembled state. Each of the plurality of diagonal braces 13B is spanned between each of the plurality of columns 11 and each of the plurality of short beams 12B in an assembled state.

[0033] 1 and 2, the ceiling opening 20C formed in the ceiling cover 20 is disposed so as to overlap in the up-down direction Z with a part of the central beam 12C and parts of the two adjacent upper openings 10A sandwiching the part of the central beam 12C. A part of the air purification filter 21 is disposed on the central beam 12C. Another part of the air purification filter 21 is disposed on one of the two upper openings 10A, an upper opening 10A1, and the remaining part of the air purification filter 21 is disposed on the other upper opening 10A2.

[0034] 1 and 2, the shape and dimensions of the air purifying filter 21 are set according to the shape and dimensions of the ceiling opening 20C so that the air purifying filter 21 covers the entire ceiling opening 20C. The opening shape of the ceiling opening 20C formed in the ceiling cover 20 is, for example, rectangular. The outer shape of the air purifying filter 21 is, for example, rectangular. The opening width of the ceiling opening 20C in the first direction X is, for example, wider than the opening width of the ceiling opening 20C in the second direction Y. The width of the air purifying filter 21 in the first direction X is, for example, wider than the opening width of the air purifying filter 21 in the second direction Y.

[0035] 1 and 2, the ceiling portion 20A of the ceiling cover 20 further includes a plurality of holding portions 22 for detachably holding the air cleaning filter 21. Each of the plurality of holding portions 22 is disposed at intervals around the periphery of the ceiling opening 20C. The ceiling portion 20A has, for example, four holding portions 22 disposed at the four corners of the ceiling opening 20C, and two holding portions 22 disposed between the four holding portions 22 in the first direction X.

[0036] 1 and 2, the air cleaning filter 21 includes a plurality of held parts 23 that are detachably held by the respective holding parts 22 of the ceiling portion 20A. The plurality of held parts 23 are arranged at intervals from one another along the outer periphery of the air cleaning filter 21. The air cleaning filter 21 has, for example, four held parts 23 arranged at the four corners and two held parts 23 arranged between the four held parts 23 in the first direction X.

[0037] 1 and 2, the ceiling cover 20 is detachable from the frame 10. The ceiling cover 20 includes a plurality of mounting members 24. Each mounting member 24 is detachable from a portion of each of the pillar 11, the long beam 12A, and the short beam 12B. Preferably, the plurality of mounting members 24 includes two or more mounting members 24 detachable from the pillar 11, two or more mounting members 24 detachable from the long beam 12A, and two or more mounting members 24 detachable from the short beam 12B.

[0038] Each mounting member 24 includes, for example, a belt-shaped member 25 having a plurality of through holes 26 formed therein and having flexibility, and a string (not shown) that is passed through the plurality of through holes 26. The belt-shaped member 25 of each mounting member 24 has a longitudinal direction and a lateral direction. The longitudinal direction of the belt-shaped member 25 of each mounting member 24 is along a direction perpendicular to the extension direction of the pillar 11, long beam 12A, or short beam 12B to which the mounting member 24 is attached. The lateral direction of the belt-shaped member 25 of each mounting member 24 is along the extension direction of the pillar 11, long beam 12A, or short beam 12B to which the mounting member 24 is attached. The belt-shaped member 25 of each mounting member 24 is fastened to the frame 10 by the string, so that the ceiling cover 20 is attached to the frame 10. The state in which each mounting member 24 is fastened to the frame 10 by the string is released, so that the ceiling cover 20 can be removed from the frame 10.

[0039] As shown in FIG. 2, the ceiling cover 20 may have two first display parts 27 that indicate an area to be placed on the long beam 12A of the frame 10, and two second display parts 28 that indicate an area to be placed on the short beam 12B. The multiple mounting members 24 are arranged on each of the two first display parts 27 and the two second display parts 28. The longitudinal direction of each of the multiple mounting members 24 arranged on the two first display parts 27 is along the second direction Y. The multiple through holes 26 of each mounting member 24 arranged on the two first display parts 27 are formed at intervals in the second direction Y. The longitudinal direction of each of the multiple mounting members 24 arranged on the two second display parts 28 is along the first direction X. The multiple through holes 26 of each mounting member 24 arranged on the two first display parts 27 are formed at intervals in the first direction X.

[0040] As shown in Fig. 3, each pillar 11 is, for example, adjustable in length. Each pillar 11 has an adjustment mechanism 11C for adjusting the length of each pillar 11. The adjustment mechanism 11C may have any configuration, but may include, for example, a first tube 11D, a second tube 11E a part of which is inserted inside the first tube 11D, and a fastener 11F fixed to the first tube 11D and capable of switching between a state in which a part of the extension direction of the second tube 11E is fastened and a state in which the part is not fastened. This makes the frame 10 height adjustable.

[0041] 3, each column 11 is integrated with, for example, two diagonal braces 13A, 13B. One end of each of the diagonal braces 13A, 13B is fixed to, for example, each column 11 so that the elevation angle of each of the diagonal braces 13A, 13B can be changed. The other end of each of the diagonal braces 13A, 13B has a first engagement portion 14 that is detachably connected to each of the long beams 12A or each of the short beams 12B.

[0042] As shown in Fig. 4, the long beam 12A has two accommodated portions 15 that are accommodated in the accommodation portions 11A of each column 11. Each accommodated portion 15 is provided at both ends of the long beam 12A. Each accommodated portion 15 extends in a direction perpendicular to the center portion extending between both ends of each long beam 12A.

[0043] As shown in FIG. 4, each long beam 12A has two second engagement parts 16 for detachably fixing the first engagement parts 14 of each brace 13A, 13B. For example, the first engagement parts 14 are formed as protrusions, and the second engagement parts 16 are formed as grooves that engage with the protrusions. The second engagement parts 16 as grooves have an open end and a terminal end. The open end of each second engagement part 16 faces the nearest accommodated part 15. The terminal end of each second engagement part 16 is disposed relatively lower than the open end. Note that the second engagement parts 16 may be formed as protrusions, and the first engagement parts 14 may be formed as grooves that engage with the protrusions.

[0044] Each of the short beams 12B has a similar configuration to the long beam 12A shown in Fig. 4. Each of the short beams 12B differs from the long beam 12A shown in Fig. 4 only in the length in the extension direction.

[0045] 5, the central beam 12C has two third engagement portions 17 for detachably fixing to the long beams 12A. The third engagement portions 17 are formed, for example, as elastically deformable engagement claws.

[0046] Preferably, the material from which the ceiling covering 20 is made is flame retardant. Each member constituting the frame 10 may have any shape, but for example, has a cylindrical shape.

[0047] <Modification> The work booth assembly 100 may be switchable between a first assembly state shown in Fig. 1 and a second assembly state shown in Fig. 6. From a different perspective, in the work booth assembly 100, the frame 10 may be changeable in size of each of the upper opening 10A and the side openings 10B1, 10B2. In this case, the frame 10 includes, in addition to the two long beams 12A used in the first assembly state shown in Fig. 1, a second long beam 12D used in the second assembly state shown in Fig. 6. The second long beam 12D is longer than the long beam 12A.

[0048] As shown in FIG. 6, the ceiling cover 20 further includes a plurality of mounting members 24 that are detachably attached to each of the second long beam 12D and the short beam 12B in the second assembly state. The ceiling cover 20 may further include a third display portion 29 in addition to the two first display portions 27 and the two second display portions 28. The first display portion 27 displays an area to be placed on the long beam 12A or the second long beam 12D. The second display portion 28 displays an area to be placed on the short beam 12B in the first assembly state. The third display portion 29 displays an area to be placed on the short beam 12B in the second assembly state. The third display portion 29 is provided at a position farther away from the ceiling opening 20C than the second display portion 28. The plurality of mounting members 24 that are detachably attached to the second long beam 12D are arranged at intervals on the two first display portions 27. The multiple mounting members 24 that are detachably attached to the long beam 12A are also detachably attached to the second long beam 12D.

[0049] In such a work booth assembly 100, a first assembly state or a second assembly state is selected according to the required width of the work space in the first direction X (the opening width of the work opening), and the first assembly state or the second assembly state can be easily realized by raising the frame 10 using the long beams 12A or the second long beams 12D according to the selection.

[0050] The second long beam 12D may be foldable. Similarly, the long beam 12A may also be foldable. The long beam 12A may also be adjustable in length. The length adjustment mechanism of the long beam 12A may be the same as that of the column 11 described above. In this case, the second long beam 12D may be prepared by adjusting the length of the long beam 12A, without being prepared as a separate member from the long beam 12A.

[0051] 7, each pillar 11 may include a caster 11G. The caster 11G is fixed to each pillar 11 so as to be able to roll on the installation surface of the work booth assembly 100. The caster 11G is fixed, for example, to the lower end of each pillar 11. Preferably, the caster 11G has a locking mechanism.

[0052] The outer shape of the frame 10 may have any shape according to the working space to be formed. The outer shape of the frame 10 may be, for example, a cube or a triangular prism. The frame 10 may have three or more columns 11 and three or more beams 12. In addition, the connection structure between each column 11 and each beam 12 may have any connection structure and is not limited to the structure described above.

[0053] <Work booth configuration> As shown in FIG. 8, the work booth 200 according to this embodiment includes the work booth assembly 100 described above and a side curtain 220.

[0054] The side curtain 220 is attached to the side portion 20B of the ceiling cover 20 of the work booth assembly 100. Specifically, the upper end portion of the side curtain 220 is attached to the side portion 20B of the ceiling cover 20. The means for attaching the side curtain 220 to the side portion 20B is not particularly limited, but for example, it is adhered by an adhesive member 230 such as an adhesive tape (see Figs. 9 and 10). Preferably, the lower end portion of the side curtain 220 is adhered to the installation surface of the work booth 200.

[0055] The side curtains 220 are provided so as to cover each of the four side openings 10B1 to 10B4. In the work booth 200, the side curtains 220 form a work opening 220A and an air supply opening 220B.

[0056] Each of the work opening 220A and the air supply opening 220B can be formed, for example, by folding or cutting off a part of the side curtain 220. The open end of the work opening 220A is adhered to the peripheral edge of the part to be treated in the workpiece by an adhesive member 240 such as an adhesive tape (see FIG. 10). The open end of the air supply opening 220B is adhered to the outer circumferential surface of the blower 300 by an adhesive member 250 such as an adhesive tape (see FIG. 9).

[0057] <Example of using the work booth> As shown in Figures 9 and 10, the work booth assembly 100 and the work booth 200 are particularly suitable for a painting process in which a water-based paint is applied to a portion of a vehicle. As shown in Figures 9 and 10, the work booth 200 is used after being set up so that only the portion 400 of the vehicle to be treated is exposed from the work opening 220A into the work space. Preferably, the height of each pillar 11 is adjusted so that the lower end 20D of the side portion 20B of the ceiling cover 20 is positioned higher than the portion 400 of the object to be treated.

[0058] When a non-treatment target portion 410 (see FIG. 10) adjacent to the treatment target portion 400 is exposed within the work opening 220A, the non-treatment target portion 410 is masked, and then the work booth 200 is set as described above. For example, in the case of a painting process in which the treatment target portion 400 is a vehicle door, the window and door knob, which are the non-treatment target portion 410, are covered with a masking sheet 420, tape 430, or the like, and then the work booth 200 is set so that the work opening 220A exposes the entire treatment target portion 400 within the work space.

[0059] After the above-mentioned treatment using the work booth 200 is completed, the side curtain 220 is removed from the ceiling cover 20 of the work booth assembly 100. The used side curtain 220 is, for example, collected as waste and recycled. When the above-mentioned treatment is to be performed again using the work booth 200, an unused side curtain 220 is attached to the ceiling cover 20 of the work booth assembly 100, the work booth 200 is reassembled, and used in the same manner. In other words, in the work booth 200, only the side curtain 220 is replaced, and the work booth assembly 100 and the blower 300 can be used repeatedly.

[0060] It should be noted that repeated use of the work booth 200 as described above gradually reduces the cleaning ability of the air cleaning filter 21. The air cleaning filter 21 is detachable from the ceiling opening 20C of the ceiling cover 20, and therefore can be replaced as needed.

[0061] <Action and effect> The work booth assembly 100 includes an assemblable frame 10 and a ceiling cover 20 that covers only the upper portion of the frame 10, and the ceiling cover 20 includes an air cleaning filter 21. Furthermore, the work booth assembly 100 can form a work booth 200 by attaching a side curtain 220 to the ceiling cover 20. Therefore, according to the work booth assembly 100, a highly clean work space can be easily formed by only separately preparing the side curtain 220 and the blower 300 that introduces air from the outside of the work booth 200 to the inside. In other words, the work booth 200 can easily form a highly clean work space by only separately preparing the blower 300.

[0062] In particular, the work booth assembly 100 and the blower 300 can be used repeatedly, and a highly clean work space can be repeatedly formed by replacing only the side curtain 220. Therefore, according to the work booth assembly 100 and the work booth 200, it is possible to realize stable work quality while reducing the initial investment and running costs compared to a work room equipped with a conventional ventilation device.

[0063] Furthermore, in the work booth assembly 100, the ceiling cover 20 covers the upper opening 10A and covers only the upper portions of each of the side openings 10B. Therefore, compared to a case in which the ceiling cover 20 is provided so as to cover most or all of each of the side openings 10B, the ceiling cover 20 is less likely to be contaminated by fine dust and the like, and more stable work quality can be achieved.

[0064] In the work booth assembly 100, since the frame 10 is height adjustable, the height of each pillar 11 can be adjusted so that the lower end 20D of the side portion 20B of the ceiling cover 20 is positioned higher than the treatment target portion 400 of the workpiece. By adjusting the height of each pillar 11 as described above, the ceiling cover 20 is less likely to be contaminated by fine dust and the like, compared to a case in which the lower end 20D of the side portion 20B is directly connected to the treatment target portion 400 of the workpiece, and more stable work quality can be achieved.

[0065] The frame 10 may include three or more columns and three or more beams in the work booth assembly 100. Such a frame 10 is relatively inexpensive and relatively easy to assemble and disassemble.

[0066] In the work booth assembly 100, each pillar 11 may include a caster 11G. In this way, the installation location of the work booth assembly 100 can be easily changed. For example, when performing a plurality of treatments on different treatment target portions of the same workpiece (as a specific example, when performing treatment on both the left and right doors of a vehicle shown in FIG. 9), the treatments can be performed continuously by only moving one set of the work booth 200 and the blower 300 without moving the workpiece or preparing and setting two sets of the work booth 200 and the blower 300. As a result, the work booth assembly 100 and the work booth 200 can improve work efficiency.

[0067] As described above, the frame 10 may be capable of changing the size of the upper opening 10A. The ceiling cover 20 may be detachable from the frame 10 regardless of the size of the upper opening 10A. In this manner, as described above, it is possible to switch between the first assembly state shown in FIG. 1 and the second assembly state shown in FIG. 6 according to the width of the required work space. The width of the required work space changes according to the size of the part to be treated. Therefore, the work booth assembly 100 and the work booth 200 as described above can be applied to various treatments in which the size of the part to be treated differs.

[0068] Although the strap of the present disclosure has been described above in each embodiment, the embodiments disclosed herein are illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims, and includes all modifications within the meaning and scope of the claims. [Explanation of symbols]
