Description

Technical Field

[0001] The present invention relates to work rainwear, which is particularly suitable for use as an outer coat to be worn over work clothes with a blower fan (sometimes referred to as air-conditioned clothes).

Background Art

[0002] Generally, in air-conditioned clothes, it is common practice to install a pair of left and right blower fans in parallel at a low position around the waist (torso) or near the hem at the back of the clothing body. However, as described in Patent Document 1 for example, when an outer coat such as a raincoat (6) is worn over such air-conditioned clothes (5), a part of the outer coat (6) that is affected by the suction force of the fan (1) adheres closely to the fan (1) from the outside (front side), preventing outside air from being sucked into the clothes (5) and impairing the function of the air-conditioned clothes (5).

[0003] Therefore, in the configuration described in Patent Document 1, a spacer (100) is detachably attached to the fan (1) of the air-conditioned clothes (5) for use.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, even if the spacer (100) for air-conditioned clothing described in Patent Document 1 is attached to the fan (1) as shown in Figure 3, the outer garment (6), even if it is not work rainwear, is always larger than the air-conditioned clothing (5). As a result, the hem of the outer garment (work rainwear) (6) is subjected to the suction force of the fan (1) and is pulled towards the spacer (100) from below, potentially blocking the downward-facing air intake of the spacer (100). Even if this risk does not exist, the amount of outside air drawn in by the fan (1) will inevitably decrease, making it impossible to cool the body quickly and efficiently.

[0006] This situation occurs in exactly the same way not only with rearward-facing configurations mounted on the back of the air-conditioned garment, but also with side-facing configurations mounted on both sides / both sides of the body (the seams extending vertically between the front and back panels), as long as the pair of left and right cooling fans are located in a low position around the waist (torso) or near the hem. [Means for solving the problem]

[0007] This invention aims to solve the above problems, and in order to achieve this objective, claim 1 describes a work rainwear that is worn as an overcoat over an air-conditioned garment, in which a pair of spacers, each having a blower fan and an air intake port opening downward to the fan, are installed in parallel at a low position around the waist or hem on the back or both sides of the garment.

[0008] The front and back panels of the garment, sewn together by a vertical seam line extending along the sides of the body, are separated by a pair of nearly symmetrical side vents cut upwards from the hem to a certain depth.

[0009] The separated front panel hems are folded back continuously by a certain width from the extension of the vertical seam line, as a pair of nearly symmetrical, thickened or reinforced side back overlapping pieces.

[0010] Each of the overlapping side back pieces is designed so as not to bend or deform in a way that would block the air intake port on the spacer from the suction force of the blower fan,

[0011] Sew only the horizontal upper edge of the side back overlapping piece that has been continuously folded backward as described above, to the corresponding mid-height position on the back panel.

[0012] Subsequently, the hem portion of the bodice is used as a hanging cover and is overlapped with the side back overlapping pieces of the front bodice from the rear, and the side back overlapping pieces and the hanging cover are each detachably fastened with a pair of male and female snap buttons, thereby enabling the side vents to be opened and closed.

[0013] Furthermore, in claim 2, a pair of nearly symmetrical left and right side back overlapping pieces are attached as separate reinforcing fabric from the main body of the front panel, and their vertical edges, with dimensions corresponding to the depth of the cutouts of the side vents, are sewn to the main body of the front panel along the cutout edges of the side vents using vertical stitching.

[0014] Similarly, the horizontal upper edge of the overlapping side back piece of the reinforcing fabric is sewn to the corresponding mid-height position of the back body using horizontal stitching.

[0015] Claim 3 is to attach either a female snap button or a male snap button, which are detachable from each other, to the upper section and the other to the lower section, in two sections to the side back overlapping piece on the front body,

[0016] By reversing the top and bottom of the above pair of male and female snap buttons, with one of them (male or female) as the upper button and the other as the lower button, and attaching both to the hanging cover on the back of the garment in two rows,

[0017] The above-mentioned side back overlapping piece and the hanging cover can be detachably fastened in two stages by a pair of male and female snap buttons located at corresponding positions on the upper and lower sections of the same piece,

[0018] The above-mentioned hanging cover can be folded inward toward the front of the garment, and the hem can be kept in a folded state by detachably fastening one of the female snap buttons (either the top or bottom) with the other male snap button.

[0019] Claim 4 is characterized in that the hanging cover is an extension fabric separate from the main body of the back panel, and the horizontal upper edge of the hanging cover of the extension fabric and the corresponding lower edge of the main body of the back panel are sewn together with a horizontal sewing thread, and at the same time, the upper edges of the overlapping pieces on both sides of the front panel are also sewn together.

[0020] Claim 5 is characterized in that each of the side back polymer pieces has a three-layer structure in which a reinforcing core made of polyvinyl chloride resin or other synthetic resin is sandwiched between two layers of the same fabric as the garment body, on the front and back.

[0021] Claim 6 describes how the side back overlapping piece on the front bodice side, when viewed from the rear, is shaped into an overall rectangular or nearly isosceles trapezoidal contour shape, where the length of the cut depth dimension of the side vents is the longer vertical side, and a certain width dimension is the shorter horizontal side.

[0022] The side back overlapping piece is characterized in that at least a certain length of the upper part of the other free vertical or sloping edge, which is not a continuous folded base from the front body side or a sewn part to the front body side, is fixed and maintained in a backward-facing folded overlapping piece portion for drainage.

[0023] Furthermore, in claim 7, the upper back fabric and the lower torso fabric of the back body are sewn together such that the gap between the outer back fabric and the inner torso fabric is divided into a pair of left and right ventilation openings, by the distance between the upper edge of the torso fabric and the lower edge of the back fabric,

[0024] The upper edge portion of the body fabric that forms the upper edge of the ventilation opening is respectively folded and sewn as a rubber bag in which the caulking rubber is stored.

[0025] It is characterized in that the rubber bag can be expanded and contracted by pulling the caulking rubber so that the size and opening shape of the ventilation port can be changed and adjusted.

Effect of the Invention

[0026] According to the above configuration of the device according to claim 1, even if a pair of left and right of the blower fan and the spacer for securing the intake port that opens downward to the fan are attached to a low position near the hem of the back (rear side) or both side surfaces of the air-conditioned clothing, the hem of the work rainwear that is put on top of the air-conditioned clothing is bent and deformed so as to be attracted to the spacer by the suction force of the blower fan, and it is possible to surely prevent the intake port of the spacer from being narrowly restricted or blocked, and there is an effect that the body of the wearer can be cooled quickly and efficiently.

[0027] That is, in the use state where the work rainwear is put on top of the air-conditioned clothing with a blower fan, the side-back overlapping piece on the front body side separated by the cut of the side vents and the hanging cover on the back body side are in a positional relationship that almost corresponds to and matches the blower fan of the air-conditioned clothing, and the intake port of the spacer that opens downward to the fan is covered, and the side-back overlapping piece is reinforced or thickened, so it does not bend and deform even when receiving the suction force of the blower fan, and there is no risk of narrowing or blocking the intake port of the spacer.

[0028] In addition, the side-back overlapping piece on the front body side is reinforced or thickened, and moreover, the hanging cover on the back body side covers and overlaps the side-back overlapping piece from the rear (outer side), so it is difficult for the hem of the work rainwear to remain turned up, and there is no risk of wetting the waist of the wearer with rainwater.

[0029] Furthermore, when work rainwear is worn over air-conditioned clothing, the side back overlapping piece on the front and the hanging cover on the back can be detachably fastened with a pair of male and female snap buttons. If the wearer feels tight or restricted when the side vents are closed, the fastening can be released to keep the side vents open, which is convenient and provides a good wearing experience during work.

[0031] Hereinafter, preferred embodiments of the present invention will be described in detail based on the drawings. Figure 1 is a rear view of an air-conditioned garment (C) worn over work rainwear according to the embodiment. The air-conditioned garment (C) is made of polyester, nylon, or other synthetic fibers with low elasticity, and an elastic cord or other elastic material is sewn into its hem (11). By tightening and fitting this around the wearer's waist (torso), the air blower fan (F), described later, draws air (outside air) into the inside of the air-conditioned garment (C), preventing that air from leaking out.

[0032] In the air-conditioned garment (C) described above, a pair of left and right cooling fans (F) are attached to the lower left and right ends of the back (back) (12) around the waist (torso) or near the hem, maintaining a constant distance apart as shown in Figure 1, and facing backward in parallel. The air (outside air) drawn in by these cooling fans (F) efficiently cools the wearer's body, providing a cool and comfortable wearing experience. However, as shown in Figure 2, the pair of left and right cooling fans (F) may also be attached to the lower positions on both sides (the body sides where the front and back panels are sewn together along the vertical direction).

[0033] In any case, the air (outside air) drawn into the inside of the air-conditioned garment (C) by the blower fan (F) circulates around the wearer's back and underarms and is discharged to the outside from the collar and sleeves of the garment (C). However, in any of the air-conditioned garments (C) shown in Figures 1 and 2, when a work rain suit (M) is worn over it, a spacer (S) is attached to the blower fan (F) from the outside as shown in Figures 3 and 4, thereby ensuring that the air intake (13) to the blower fan (F) is maintained.

[0034] Figures 3-6 show an example of the preferred spacer (S), which is a lightweight product comprising a spacer body (14), an upper and lower pair (two tiers) of stretchable elastic cords (15), and a clothing snagging prevention band (16).

[0035] The spacer body (14) is made from a flat sheet of polyethylene foam, which is highly flexible and elastic, and is shaped into an approximately isosceles trapezoid or other symmetrical contour when viewed from the front. Furthermore, a pair of upper and lower rubber bands (15) are attached horizontally parallel to the spacer at an intermediate height, holding it in an arc-shaped curve that can surround the blower fan (F) from the outside when viewed from the flat / bottom surface, and its lower surface (bottom surface) opens as an air intake (13) for the blower fan (F). (R) indicates the opening width of the air intake (13). The clothing suction prevention band (16) is a flat band made of the same material as the spacer body (14) and is pivotally attached horizontally to the lower end of the spacer body (14).

[0036] As is clear from the mounting and usage state of the blower fan (F) and spacer (S) shown in Figure 7, the male screw (19) engraved on the circumferential surface of the guard body (18) inserted from the outside into the circular fan mounting opening (17) formed at the predetermined height position of the air-conditioned garment (C), and the female screw (21) on the circumferential surface of the fan body (20) screwed into the male screw (19) from the inside of the garment (C), and the flange (22) protruding from the circumferential surface of the fan body (20) In the case of a type where the blower fan (F) is sandwiched between the flange (23) protruding from the circumferential surface of the guard body (18) and the periphery of the fan mounting opening (17) in the garment (C) from both the inside and outside directions, the upper and lower pair of rubber cords (15) of the spacer (S) can be attached to the air-conditioned garment (C) together with the blower fan (F) by screw fastening the fan body (20) of the blower fan (F) to the guard body (18).

[0037] In this case, the fan body (20) has a relatively deep bowl shape because it houses a propeller (blower blades) (25) that is rotated by a motor (24), while the guard body (18) has a shallow dish or disc shape. In both cases, numerous ventilation holes (26) (27) are distributed through the intersecting longitudinal and transverse arrangement of ribs. A reinforcing sheet (not shown) may be sewn or glued to the fan mounting opening (17) in a border-like manner.

[0038] Furthermore, as shown in Figure 8, which corresponds to Figure 7, the fan body (20) with the guard body (18), which is molded as a continuous, integrated piece, is inserted from the outside into the fan mounting opening (17) of the air-conditioned garment (C). The female thread (30) engraved on the circumferential surface of a separate tightening ring (29) is screwed into the male thread (28) on the circumferential surface of the fan body (20) from the inside of the garment (C), and the flange (31) protruding from the circumferential surface of the tightening ring (29) and the fan body are fastened together. In the case of a type where the blower fan (F) is sandwiched between the flange (32) protruding from the circumferential surface of the body (20) and the periphery of the fan mounting opening (17) on the garment (C) from both the inside and outside directions, the upper and lower pair of rubber cords (15) of the spacer (S) can be attached to the air-conditioned garment (C) together with the blower fan (F) by screwing the fan body (20) with the guard body (18) and the tightening ring (29).

[0039] (33) is a gripping piece for pulling the rubber cord (15) when attaching or detaching the spacer (S) as shown in Figures 7 and 8, and is integrally extended from the middle of the rubber cord (15) in opposing vertical directions.

[0040] Furthermore, the above-mentioned spacer (S) functions as a protector that can protect the blower fan (F) from damage from the outside, and as long as an air intake port (13) with an opening width (R) (for example, about 10-12 cm) that is approximately the same as the outer diameter (diameter) of the blower fan (F) of the air-conditioned garment (C) can be secured, other configurations may be adopted in addition to those shown in Figures 3-6, and the method of attachment to the air-conditioned garment (C) and its blower fan (F) is not limited to those shown in Figures 7 and 8, as long as the spacer (S) can be attached and detached.

[0041] Next, Figures 9-23 show a basic embodiment of work rainwear (M) to be worn over the above-mentioned air-conditioned clothing (C) when performing electrical work, construction work, road construction, and various other on-site work outdoors. The garment body (34) and head hood (35) of the rainwear (M) are made of polyester, nylon, or other low-stretch synthetic fibers, just like the air-conditioned clothing (C), but the surface is treated with water repellency, while the back surface is given waterproofing by lamination or coating of polyurethane resin (PU) or polyvinyl chloride resin (PVC).

[0042] (36) is a pair of left and right front panels of the garment body (34), with a sliding fastener (37) for opening and closing extending along its central longitudinal section. (38) is a back panel consisting of an upper back fabric (38a) and a lower torso fabric (38b), with both fabrics (38a) and (38b) sewn together by a horizontal seam (39) connecting the area near both armpits on the back panel (38). (40) is a pair of left and right long sleeves, both sewn into a tubular shape by a seam (41) extending horizontally along the side of the armpit, while the pair of left and right front panels (36) and back panel (38) are sewn together by a vertical seam (42) extending along the side of the body.

[0043] Furthermore, the bases of both long sleeves (40) are sewn to the front body (36) and back body (38) by a diagonal sewing line (43) that connects the shoulder and underarm areas, connecting to the intersection of the vertical and horizontal sewing lines (42) and (41). However, in the illustrated embodiment of the rainwear (M), the vertical sewing line (42) between the front body (36) and back body (38) does not reach the hem (lower end), and a pair of nearly symmetrical side vents (V) are formed at the hem. (H) is the depth of the side vents (V) cut upward from the hem, and is dimensioned to approximately 23 cm.

[0044] Furthermore, the horizontal sewing line (41), vertical sewing line (42), and diagonal sewing line (43) are sealed from the back side by waterproof tape (not shown) that is bonded or heat-fused to them, thereby preventing rainwater from seeping through the perforations.

[0045] Then, of the front body (36) and back body (38), whose hems are separated by the cuts in the side vents (V), the side back overlapping piece (44), which is shaped into an overall rectangular or nearly isosceles trapezoidal contour as viewed from the rear as shown in Figures 13 and 17, has its vertical side (Y) sewn along the cut opening edge of the side vent (V). The vertical side (Y) of the side back overlapping piece (44) is shaped as an overall rectangular or nearly isosceles trapezoidal contour as viewed from the rear as shown in Figures 13 and 17, where the depth dimension (H) of the cuts in the side vents (V) is the longer vertical side (Y) and a certain width dimension (W) (for example, about 8 cm) is the shorter horizontal side (X).

[0046] In other words, the nearly symmetrical left and right side back overlapping pieces (44) are attached to the front body (36) as separate linings, with their respective long vertical edges (Y) sewn along the cut-out edges of the side vents (V) on the front body (36).

[0047] (45) is the longitudinal stitching thread of the side back overlapping piece (44) along the cut-out edge of the side vent (V), and in Figure 13 it is arranged in a row along a line separate from the longitudinal stitching line (42) along the side of the body, but of course it may also be sewn to the hem of the front body (36) with the longitudinal stitching thread (45) which extends the longitudinal stitching line (42) downward.

[0048] On the other hand, the horizontal upper edge portion of the side back overlapping piece (44), which is a short horizontal side (X) with a constant width dimension (W), is sewn to the corresponding mid-height position (lower torso fabric (38b)) of the back body (38) by horizontal sewing thread (46).

[0049] Furthermore, as suggested by the enlarged cross-sectional views in Figures 14-16 and the schematic cross-sectional view in Figure 18, the side back polymerized piece (44) used as the reinforcing fabric has a three-layer structure, consisting of two layers (a) and (b) of the same fabric (synthetic fibers such as polyester or nylon) as the main body of the garment (34), with a thick interlining made of polyvinyl chloride resin (PVC) or other synthetic resin sandwiched in between (c).

[0050] When the work rainwear (M) is worn over the above-mentioned air-conditioned garment (C), the positional relationship between the left and right pair of overlapping side back pieces (44) is set to substantially correspond to that of the air-conditioning garment (C)'s fan (F) and the spacer (S) attached to the fan (F). As a result, the overlapping side back pieces (44) hang down so as to face the area around the downward-opening air intake (13) of the spacer (S). Therefore, under the suction force of the air-conditioning fan (F), they bend and deform as shown in Figure 19, potentially blocking the air intake (13) of the spacer (S) to the fan (F), and even if not completely blocking it, reducing the amount of air the fan (F) can draw in.

[0051] To prevent this, the above-mentioned side back polymerized piece (44) is reinforced or thickened to prevent bending deformation. If this purpose can be achieved, the structure is not limited to the three-layer structure of the illustrated embodiment. For example, a two-layer structure in which the main fabric of the front body (36) is lined and integrated with the above-mentioned polyvinyl chloride resin, rubber, felt, leather, or other structures may be adopted.

[0052] Furthermore, the other free vertical or sloping edge of the side back overlapping piece (44), which has a rectangular or nearly isosceles trapezoidal contour shape, that is not sewn to the front body (36), is fixed and maintained in a backward-facing (outward-facing) folded overlapping piece portion (47) for drainage purposes, as shown in Figures 13 and 16, for at least a certain length of its upper portion, thereby performing a drainage function for rainwater that enters from the side of the side vent (V).

[0053] Furthermore, the hem portion of the back panel (38), separated by the cuts in the side vents (V), acts as a hanging cover (48) and overlaps the side back overlapping piece (44) of the front panel (36) from the rear (outside).

[0054] In the basic embodiment shown in Figures 9-23, the hem of the back panel (38), which forms the drape cover (48), is a separate extension fabric from the main body of the back panel (38). The horizontal upper edge of this extension fabric and the corresponding horizontal lower edge of the main body of the back panel (38) are sewn together with a horizontal sewing thread (49) parallel to the horizontal sewing line (39). The drape cover (48) as an extension fabric is made of the same fabric (synthetic fiber such as polyester or nylon) as the main body of the back panel (38).

[0055] Furthermore, the horizontal sewing thread (49) and the horizontal sewing thread (46) of the side back overlapping piece (44) are used together to sew the horizontal upper edge of the side back overlapping piece (44) to the back body (38) at the same time. However, it is also possible to use a single piece of fabric for the entire back body (38), including the drape cover (48), and especially the torso fabric (38b).

[0056] In any case, the left and right side back overlapping pieces (44) attached to the hem of the front body (36) and the hanging cover (48) on the back body (38) side that covers and overlaps them from the rear (outside) are detachably fastened together via a pair of male and female snap buttons (eyelets) (50a) (50b) that are installed in two corresponding rows, upper and lower.

[0057] In other words, as shown in the schematic cross-sectional view of Figure 20, one of the female snap buttons (50a) and male snap buttons (50b) that can engage and disengage from each other (male snap button in the example) is attached to the side back overlapping piece (44) on the front body (36) side in two rows, one above the other, while the other (female snap button in the example) is attached to the drape cover (48) on the back body (38) side in two rows, one above the other, corresponding to the position. By engaging the female snap button (50a) and the male snap button (50b), the side vent (V) can be closed, and by releasing the engagement, the side vent (V) can be opened, allowing for the use of both states.

[0058] In particular, as shown in the other schematic cross-sectional view in Figure 21, it is preferable to attach either the female snap button (50a) or the male snap button (50b) (the male snap button in the example) to the upper position and the other (the female snap button in the example) to the lower position, both in two positions to the side back overlapping piece (44) on the front body (36) side, and also to reverse this and attach either the female snap button (50a) or the male snap button (50b) (the female snap button in the example) to the upper position and the other (the male snap button in the example) to the lower position, both in two positions to the drape cover (48) on the back body (38) side.

[0059] This arrangement allows the side back overlapping piece (44) and the hanging cover (48) to be detachably locked together in two stages, upper and lower, even with this configuration. This not only allows for both closed and open states of the side vent (V), but also has the advantage of preventing the hanging cover (48) on the back body (38) side from being folded inward (inside out) as shown in Figures 22 and 23, and the pair of female snap buttons (50a) and male snap buttons (50b) on the top and bottom from being detachably locked together, thereby keeping the hanging cover (48) in a so-called hemmed, folded-over state. Furthermore, the hanging cover (48) on the back body (38) side, which is thinner than the side back overlapping piece (44) on the front body (36) side, from being sucked up by the fan (F) of the air-conditioned garment (C) and blocking the air intake (13) of the spacer (S).

[0060] In the basic embodiment shown in Figures 9-23, the side back overlapping piece (44) on the front body (36) is treated as a separate piece of fabric from the main body of the front body (36), and its vertical side (Y), which has dimensions corresponding to the cut depth (H) of the side vent (V), is sewn along the cut opening edge of the side vent (V) on the main body of the front body (36) using the vertical side sewing thread (45), while the drape cover (48) on the back body (38) is treated as a separate extension piece from the main body of the back body (38), and its water The flat upper edge is sewn to the horizontal lower edge of the back body (38) using horizontal sewing thread (49). However, as shown in the modified embodiments in Figures 24 and 25, which correspond to Figures 13 and 15, the side back overlapping piece (44) on the front body (36) side may be folded backward by a certain width dimension (W) that becomes the horizontal side (X) from the extension of the vertical sewing line (42) that extends along the side of the body, and the reinforcing interlining described above may be backed and integrated into the inside of the folded portion. Sewing only the horizontal upper edge of the folded portion with a certain width dimension (W) to a corresponding intermediate height position on the back body (38) side using horizontal sewing thread (46) is the same as in the basic embodiments in Figures 9 to 23.

[0061] In this case, the other free vertical or inclined side of the side back overlapping piece (44), which has an overall rectangular or nearly isosceles trapezoidal contour shape, that does not become a continuous folded base from the front body (36) side, is fixed and maintained in a rearward (outward) folded state for at least a certain length on its upper side as a water-draining folded overlapping piece (47), thereby performing a water-draining function for rainwater that enters from the side of the side vent (V).

[0062] In the modified embodiments shown in Figures 24 and 25, the entire back panel (38) is a single piece including the hem cover (48). However, since the other components are substantially the same as those of the basic embodiments shown in Figures 9 to 23, we will simply use the same reference numerals as in Figures 9 to 23 in Figures 24 and 25, and omit a detailed explanation.

[0063] In the work rainwear (M) according to the basic embodiment shown in Figures 9-23, the back fabric (38a) and the torso fabric (38b) of the back body (38) are sewn together by a horizontal seam line (39) connecting the area near both armpits on the back body (38). Furthermore, it is preferable to maintain the above pair of upper and lower fabrics (38a) and (38b) at a position almost directly above the horizontal seam line (39), with the back fabric (38a) on the outside and the torso fabric (38b) on the inside, as shown in Figures 26-28, and with an overlap of a distance (D) between the lower edge (u) of the back fabric (38a) and the upper edge (t) of the torso fabric (38b). This distance is a constant overlap amount (D), for example, about 7-8 cm.

[0064] Then, a certain width of the intermediate (central) portion (51) between the back fabric (38a) and the torso fabric (38b), which overlap by a certain amount (D), is sewn and closed as shown in Figures 27 and 28. The gaps between the sides, which are sewn and closed along the vertical sewing line (42) along the sides of the body, and the intermediate portion (51) are divided into a pair of left and right ventilation openings (52) that each open by a certain width (L) (for example, about 10 to 15 cm), and are arranged in a parallel state.

[0065] In this way, the pair of left and right vents (52) will function as ventilation for the work rainwear (M), and if the work rainwear (M) is worn over an air-conditioned garment (C) which has a pair of left and right blower fans (F) attached in roughly corresponding positions to the vents (52), the vents (52) can also function as air intakes for the blower fans (F). In any case, the vents (52) are concealed from view from the outside, and there is no risk of rainwater entering from above.

[0066] In particular, the upper edges (t) of the body fabric (38b) that will frame the pair of left and right ventilation holes (52) are folded and sewn together as a rubber bag (54) containing elastic (flat elastic) (53), as shown in Figures 27-29. In this case, one end of the elastic (53) and its rubber bag (54) on the middle (center) side (51) is sewn shut and fixed, while the other end of the rubber bag (54) on the side is left open so that the elastic (53) can be pulled out and operated from there.

[0067] (55) is a button sewn onto the upper edge (t) of the body fabric (38b) in a position facing the other open end of the rubber bag (54), and (56) is at least two buttonholes (slits) that are distributed at regular intervals along the length of the elastic cord (53). By pulling the elastic cord (53) out of the rubber bag (54) and reattaching the buttonholes (56) to the buttons (55), the tension of the elastic cord (53) can be adjusted, the rubber bag (54) can be stretched and contracted, and the state can be maintained.

[0068] By pulling out the elastic cord (53), the rubber bag (54) bordering the upper edge of the opening of the ventilation hole (52) is stretched, causing the torso fabric (38b) and back fabric (38a) of the body (38) to expand and bend in an arc shape in opposing inward and outward directions, thereby changing and adjusting the size (degree of opening) and shape of the ventilation hole (52). This has the advantage of allowing for an appropriate increase or decrease in the amount of ventilation for the wearer of the rainwear (M) and the amount of outside air drawn in by the fan (F) of the air-conditioned garment (C).

[0069] Furthermore, the torso fabric (38a) of the back panel (38) is folded and sewn at its upper edge (t) as a rubber pocket (54), and then, at a slightly lower height, it has a double folded section (57) as shown in the schematic cross-sectional view of Figure 28, which is folded inward once and makes a U-turn upward, and then folded inward again and makes a U-turn downward.

[0070] Moreover, the folded and overlapped lower edge portion (u) of the back fabric (38a) and the body fabric (3 The double-folded portion (57) of 8b) is crimped and integrated with a pair of drainage eyelets (58) on both sides (left and right ends) of the back body (38) and is in a superimposed state. Even when the wearer is in a working posture where their waist is higher than their head, the double-folded portion (57) prevents rainwater from entering due to backflow, and the eyelets (58) prevent rainwater from accumulating in the left and right corners of the back body (38).

[0071] It goes without saying that preferred configurations such as providing ventilation holes (52) are not limited to the work rainwear (M) according to the basic embodiment described above, but can also be adopted for the rainwear (M) according to the modified embodiment shown in Figures 24 and 25.

[0072] The work rainwear (M) of the illustrated embodiment has the above configuration, and when it is worn over the air-conditioned garment (C) with a fan (F) shown in Figures 1-4, as suggested in Figures 30 and 31, the side back overlapping piece (44) on the front body (36) side, separated by the cutouts of the side vents (V), and the hanging cover (48) on the back body (38) side are in a positional relationship that is almost in correspondence with the fan (F) of the air-conditioned garment (C), and the spacer (S) that opens downwards toward the fan (F) As it hangs down to cover the air intake (13) of the spacer (S), the side back overlapping piece (44) is reinforced or thickened, and even when subjected to the suction force of the blower fan (F), it bends and deforms so as to be drawn towards the air intake (13) of the spacer (S), so there is no risk of narrowing or restricting the air intake (13), let alone blocking it. As a result, even when wearing rainwear (M) as an overlay, the blower fan (F) of the air-conditioned garment (C) can quickly and efficiently cool the wearer's body.

[0073] When wearing the rainwear (M) as a layer, if the side back overlapping piece (44) on the front body (36) and the hanging cover (48) on the back body (38) are detachably fastened together with the pair of male and female snap buttons (50a) and (50b) respectively, and the side vents (V) are kept closed, causing a restrictive feeling for the wearer and making it difficult to work in a free posture, then, as suggested in Figures 32 and 33, the fastening of the snap buttons (50a) and (50b) can be released to open the side vents (V), thereby relieving the aforementioned feeling of restriction.

[0074] Furthermore, the side vents (V) can be opened, which is convenient because, for example, if the wearer is carrying a tool pouch (waist bag) attached to the waist belt of their trousers while performing overhead line work, they can easily insert their fingers into the open side vents (V) to take tools in and out of the tool pouch.
