Description

[Technical Field]

[0001] The present invention relates to a fan-equipped work raincoat that can be worn over fan-equipped work clothes when working in rainy weather while wearing the fan-equipped work clothes. [Background technology]

[0002] As described in paragraph 0002 of Patent Document 1 (JP 2018-12908 A), there are two types of fan-equipped workwear: non-waterproof, non-stuffy fan-equipped workwear for sunny days, and waterproof fan-equipped workwear for rainy days. While fan-equipped workwear for rainy days can be worn on sunny days, fan-equipped workwear made from non-breathable materials tends to become stuffy inside, making it particularly hot when worn on sunny days. Fan-equipped workwear made from breathable materials is expensive, and despite its high price, it is less comfortable than fan-equipped workwear for sunny days. In order to solve such problems, Patent Document 2 (Utility Model Registration No. 3225346) describes the attachment of a sieve-shaped cover part (152) to cover the rotating blade part (151) of the electric fan (15) of the work clothes (1) (fan-equipped work clothes), and the attachment of an air intake spacer (5) having a plurality of protrusions (51) facing the cover part (152) to the underside of the back of the raincoat (2) worn over the work clothes (1), thereby ensuring an air flow path (see especially paragraphs 0014, 0015, 0034 and Figures 1 and 2). In addition, Patent Document 3 (JP 2020-172899 A) describes that when a raincoat (10) is worn over clothing (1) (fan-equipped workwear) equipped with a cooling fan (5) having a fan cover (3), the thickness of the fan cover (3) protruding from the outer surface of the clothing (1) creates a space (11) between the clothing (1) and the raincoat (10), and outside air (4) can be taken in through air intakes (9) opening on the peripheral side of the fan cover (3) (see, in particular, paragraphs 0019-0020 and Figure 1).

[0003] However, the fan hood described in Patent Document 1 is detachable from the fan of the fan-equipped workwear, and is not intended to be worn as a raincoat over the fan-equipped workwear. Furthermore, the cover part (152) and air intake spacer (5) described in Patent Document 2 and the fan cover (3) described in Patent Document 3 all create a space between the fan-equipped work clothes and the raincoat, ensuring a flow path for taking in air from the bottom of the raincoat, which creates a problem in that when the bottom of the raincoat sticks to the body, it becomes difficult to take in air from the air intake of the electric fan (15) or cooling fan (5).

[0004] [Patent Document 1] JP 2018-12908 A (Patent No. 6394930 A) [Patent Document 2] Utility Model Registration No. 3225346 [Patent Document 3] Japanese Patent Application Publication No. 2020-172899 Summary of the Invention [Problem to be solved by the invention]

[0005] The first objective of the present invention is to solve these problems and provide a fan-equipped work raincoat that can reliably take in air from the air inlet of the electric fan even in situations where the bottom of the raincoat sticks to the body, and the second objective is to provide a fan-equipped work raincoat that can be adapted to various sizes and types of fan-equipped workwear. [Means for solving the problem]

[0006] The invention of claim 1 is a fan-equipped work raincoat that can be worn over fan-equipped work clothes, which have an electric fan attached to the back of the work clothes that covers the upper body to take in outside air, The raincoat itself, A ventilation area provided on the back of the raincoat body; A ventilation duct is provided which covers the entire ventilation area, has an opening below the ventilation area, and has an outer edge other than the opening attached to the front side of the raincoat body, The ventilation area can be overlapped with the air intake area of ​​the electric fan when the raincoat body is worn over the fan-equipped workwear, the ventilation duct is waterproof and bulges outward so that the ventilation area communicates with the opening; The attachment portion between the outer edge of the ventilation duct and the raincoat body is waterproofed.

[0007] The invention according to claim 2 is the fan-equipped work raincoat according to claim 1, The area of ​​the ventilation area is 2 to 5 times the area of ​​the air supply area.

[0008] The invention according to claim 3 is the fan-equipped work raincoat according to claim 1 or 2, The ventilation duct is characterized by comprising a waterproof outer layer member and a bulging member that keeps the outer layer member bulged outward. [Effects of the Invention]

[0009] The fan-equipped work raincoat of the invention according to claim 1 comprises a ventilation area provided on the back of the raincoat body, and a ventilation duct that covers the entire ventilation area, has an opening below the ventilation area, and the outer edge other than the opening is attached to the front side of the raincoat body, The ventilation area can be overlapped with the air intake area of ​​the electric fan when the raincoat is worn over the fan-equipped workwear. The ventilation duct bulges outward so that the ventilation area and the opening are in communication, so that even when the bottom of the raincoat body sticks to the body, air can be reliably taken in from the air intake port of the electric fan through the ventilation duct simply by overlapping the ventilation area with the air intake area of ​​the electric fan while wearing the fan-equipped work raincoat over the fan-equipped work clothes. In addition, the ventilation duct is waterproof, and the attachment point between the outer edge of the ventilation duct and the raincoat body is waterproofed, so even if it starts raining while working in fan-equipped work clothes for sunny weather, simply putting on the fan-equipped work raincoat will prevent rain from getting on the electric fan or rainwater from seeping in, allowing you to continue working safely without having to change into fan-equipped work clothes for rainy weather. Furthermore, it is economical because there is no need to prepare fan-equipped work clothes for rainy weather.

[0010] According to the invention of claim 2, in addition to the effects of the fan-equipped work raincoat of the invention of claim 1, the area of ​​the ventilation area is 2 to 5 times the area of ​​the air supply area, so it can be adapted to various sizes and types of fan-equipped workwear, and the ventilation area of ​​the fan-equipped work raincoat and the air supply area of ​​the electric fan can be easily overlapped.

[0011] According to the invention of claim 3, in addition to the effects of the fan-equipped work raincoat of the invention of claim 1 or 2, the ventilation duct is made up of a waterproof outer layer member and a bulging member that keeps the outer layer member bulged outward. Therefore, the ventilation duct can be created simply by making the outer layer member from a general waterproof fabric and attaching the bulging member to the exterior member.

[Figure 5] FIG. 10 is a front view of the fan-equipped work raincoat according to Example 2 with the front body part open. DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, embodiments of the present invention will be described with reference to examples. [Example]

[0014] FIG. 1 is a rear view of the fan-equipped work raincoat according to the first embodiment, and FIG. 2 is a front view of the fan-equipped work raincoat according to the first embodiment with the front body part open. The fan-equipped work raincoat of Example 1 is a raincoat that can be worn over fan-equipped work clothes, which have an electric fan attached to the back of the work clothes that covers the upper body to take in outside air, as shown in Figures 1 and 2, and has the following configuration. (1) A raincoat body 5, which is made of a waterproof material and has a back body 1, a front body 2, sleeves 3, and a collar 4 sewn together, and can be worn to keep the upper body from getting wet in the rain. (2) Two square holes 7 are provided on the left and right sides of the back body 1 so that when the raincoat body 5 is worn over the fan-equipped work clothes, the entire area where the raincoat body 5 and the air intake port of the electric fan 11 (Figure 3) come into contact (hereinafter referred to as the "air intake area 6") overlaps. The length of one side of the square hole 7 is slightly larger than the diameter of the air supply area 6. (3) Ventilation ducts 10 that completely cover the two square holes 7, have openings 8 below the holes 7, and have their outer edges 9 (thick line portions in Figure 1) other than the openings 8 attached to the front side of the raincoat body 5, with the attachment portions treated with waterproofing. The ventilation duct 10 is waterproof and is kept in an outwardly bulging state regardless of the wearer's posture or weather conditions such as wind, so that the hole 7 and the opening 8 are always in communication with each other.

[0015] FIG. 3 is a diagram showing the configuration of the ventilation duct 10 according to the first embodiment. As shown in Figure 3(a), the ventilation duct 10 of Example 1 covers the entire square hole 7 provided in the back body 1, and as shown in Figure 3(b), it has an outer layer member 12 made of the same waterproof material as the raincoat body 5 from the outside to the lower end, an inner layer member 13 made of mesh fabric that covers the inner surface of the outer layer member 12 on the inside, and a bulging member 14 between the outer layer member 12 and the inner layer member 13 that keeps the ventilation duct 10 bulging outward. The bulging member 14 is a flexible rectangular resin plate, and can be inserted or removed between the outer layer member 12 and the inner layer member 13 by opening a fastener 15 provided at the boundary between the inside of the lower end of the outer layer member 12 and the lower end of the inner layer member 13. Then, by closing the fastener 15 after inserting the bulging member 14, the bulging member 14 maintains a stable shape even when subjected to a small external force.

[0016] The configuration of the fan-equipped work raincoat of Example 1 is as described above, so when the fan-equipped work raincoat of Example 1 is worn over fan-equipped work clothes for sunny weather, the hole 7 and the air intake area of ​​the electric fan 11 can be overlapped. The ventilation duct 10 is always kept inflated outward regardless of the posture of the wearer or weather conditions such as wind, so that the outside air taken in from the opening 8 is reliably sent to the air intake port of the electric fan 11 via the ventilation duct 10 and the hole 7. Furthermore, one snap button 16 is attached to the center of the lower end of the outer layer member 12, and the other snap button 17 is attached to the center of the part of the back body 1 facing the opening 8, so that by fastening these, the opening 8 can be made smaller. Examples of cases where it is better to make the opening 8 smaller include when it is raining heavily and rainwater is easily sucked in through the opening 8, or when working in a narrow space and you want to make the opening 8 thinner. [Example]

[0017] FIG. 4 is a rear view of the fan-equipped work raincoat according to the second embodiment, and FIG. 5 is a front view of the fan-equipped work raincoat according to the second embodiment with the front body part open. 4 and 5, the fan-equipped work raincoat of Example 2 differs from the fan-equipped work raincoat of Example 2 only in that circular holes 18 having a diameter twice the diameter of the circular air supply area 6 are provided on the left and right sides of the back body 1, and large ventilation ducts 19 that can completely cover each of the two circular holes 18 are attached to the front side of the raincoat body 5. Therefore, the components other than the circular holes 18 and the large ventilation ducts 19 are assigned the same numbers in Figures 4 and 5 as in Figures 1 to 3, and detailed explanations will be omitted.

[0018] Like hole 7 in Example 1, circular hole 18 in the fan-equipped work raincoat of Example 2 can be overlapped with air intake area 6 when raincoat body 5 is worn over the fan-equipped workwear, and because the diameter of hole 18 is twice the diameter of air intake area 6, even if the position of electric fan 11 installed on the fan-equipped workwear is slightly misaligned up, down, left, or right, it is easy to overlap hole 18 with the air intake area, making it possible to provide a fan-equipped work raincoat that can be adapted to various sizes and types of fan-equipped workwear. Furthermore, since the size of the ventilation duct 19 according to the second embodiment is larger than the size of the ventilation duct 10 according to the first embodiment, the opening 8 is also larger, which has the effect of more reliably sending the outside air taken in through the opening 8 to the air intake port of the electric fan 11.

[0019] Modifications of the first and second embodiments are listed below. (Modification 1) In the first and second embodiments, holes 7 and 18 are provided in the back body 1 of the raincoat body 5, but mesh or lattice-like members may be provided in the holes 7 and 18 portions. Therefore, in the claims, "ventilation area" is used instead of "hole." (Variant 2) The length of one side of the square hole 7 in the fan-equipped work raincoat of Example 1 is slightly larger than the diameter of the air supply area 6, and the diameter of the circular hole 18 in the fan-equipped work raincoat of Example 2 is twice the diameter of the air supply area 6, but the shapes of the holes 7 and 18 are not limited to square or circular, and may be polygonal or elliptical other than square. Furthermore, the size of these holes should be such that they can be overlapped with the air intake area 6 when the raincoat main body 5 is worn over the fan-equipped work clothes, but if they are too small it will be difficult to overlap them, and if they are too large it will be difficult to maintain the ventilation ducts 10, 19 in a state where they bulge outward, and using a hard material to maintain this state will get in the way of work; therefore, the area of ​​the holes 7 (ventilation area 6) on the back body should be 2 to 5 times the area of ​​the air intake area 6 for ease of use, and 4 to 5 times the area of ​​the air intake area 6 will make it compatible with various sizes and types of fan-equipped work clothes.

[0020] (Variation 3) In the fan-equipped work raincoats of Examples 1 and 2, holes 7 and 18 overlap with air supply area 6 simply by putting raincoat body 5 over the fan-equipped work clothes, but temporary fastening members such as hook-and-loop fasteners, hooks, magnets, attachments, etc. may be provided near holes 7 and 18 to temporarily fasten the back of raincoat body 5 to the back of the fan-equipped work clothes or electric fan 11. Furthermore, a temporary fastening auxiliary member may be attached to the fan-equipped workwear to make temporary fastening easier.

[0021] (Variation 4) In the fan-equipped work raincoats according to Examples 1 and 2, the bulging member 14 can be inserted and removed between the outer layer member 12 and the inner layer member 13 by opening the zipper 15, but the zipper 15 need not be provided. Also, the bulging member 14 may be attached to the inside or outside of the outer layer member 12 by a fastening means such as adhesion, fusion, sewing, or a hook, without using the inner layer member 13, and the outer layer member 12 itself may be formed from a waterproof material with a shape that bulges outward. (Modification 5) In the fan-equipped work raincoats according to Examples 1 and 2, the opening 8 can be made smaller by fastening one 16 and the other 17 of the snap buttons, but these do not have to be. Also, instead of snap buttons, fasteners such as hook and loop fasteners, hooks, magnets, etc. may be used to make the opening 8 smaller. [Explanation of symbols]
