Description

[Technical Field]

[0001] The present invention relates to a collar gap securing device for securing a gap between the collar of a fan-equipped work suit and a worker's neck, and a cooling air circulation method for efficiently circulating outside air taken into the fan-equipped work suit as cooling air. [Background technology]

[0002] These days, many workers wear work clothes with small electric fans attached to them when working on-site in the summer. Fan-equipped work clothes are designed to cool the body by evaporating sweat and circulating outside air drawn in by a fan, which cools the sweat.

[0003] As a workwear measure to prevent heatstroke in hot weather, there is a jacket with an electric fan attached to the back that can be worn over casual clothing. When the electric fan is turned on, outside air is taken in through an air intake port on the back, causing the fabric to expand, and the taken-in air flows along the body and is released from the neck and cuffs, using the evaporative cooling effect to cool the wearer's body (see paragraph

[0003] and Figure 1 of Patent Document 1).

[0004] There is also a raincoat that is worn over work clothes equipped with an electric fan, and has a ventilation spacer that separates the work clothes from the upper surface of the shoulders or the upper surface of the sleeves of the raincoat jacket, forming a gap between them. This ventilation spacer serves as a flow path for air taken in through the air intake of the work clothes, and also prevents the raincoat jacket from sticking to the body when wet with rain (see Patent Document 2). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2018-131713 [Patent Document 2] Utility Model Registration No. 3225346 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the case of the fan-equipped workwear of Patent Document 1, if the cooling air inside the workwear does not circulate properly, the effectiveness of lowering the worker's body temperature will be reduced. For example, in actual work, workers often carry field notebooks, writing implements, mobile phones, voltage detectors, etc. in the breast pockets of their casual clothes, and they often work in cramped positions such as slouching. In such conditions, the outside air taken in as cooling air inside the fan-equipped workwear does not circulate properly, and the function of lowering body temperature will be reduced.

[0007] There are inner spacers to ensure the circulation of cooling air, but because they lack rigidity, depending on the worker's posture, they cannot form gaps to ensure the circulation of cooling air, and the chest pockets may stick tightly to the body, making it difficult for the outside air taken in by the sleeves to escape to the sleeves. Also, when performing delicate manual work while bending forward, the collar of the work clothes sticks tightly to the neck, making it difficult for the cooling air to escape through the collar.

[0008] Furthermore, the ventilation spacer in Patent Document 2 forms a flow path for air taken in through the air inlet of the workwear, but it prevents the rain-soaked raincoat jacket from sticking to the body, and the air is discharged from the outlets at the cuffs of the raincoat, not around the neck. Therefore, the air circulation path inside the raincoat is restricted, and the function of lowering body temperature is reduced.

[0009] The object of the present invention is to provide a collar gap securing device for securing an air exhaust gap between the collar of a fan-equipped work suit and the worker's neck, and a cooling air circulation method that can efficiently circulate outside air taken into the fan-equipped work suit as cooling air. [Means for solving the problem]

[0010] The collar gap securing device of the invention of claim 1 comprises a flexible electrical conduit made of synthetic resin that has rigidity and flexibility and is hung around the neck of a worker, and an air vent hole that is provided in the flexible electrical conduit and is positioned in a direction that will come into contact with the worker's neck when the flexible electrical conduit is hung around the worker's neck, and is characterized in that when the worker wears fan-equipped work clothes with the flexible electrical conduit hung around his neck, an air exhaust gap is secured between the collar of the fan-equipped work clothes and the worker's neck to allow air to escape.

[0011] A cooling air circulating method according to the invention of claim 2 comprises the steps of: attaching the collar gap securing device according to claim 1 to the neck of the worker; having the worker wear fan-equipped work clothes with the collar gap securing device attached to the worker's neck; securing an air exhaust gap for air to escape between the collar of the fan-equipped work clothes and the worker's neck using the collar gap securing device; operating the fan of the fan-equipped work clothes; drawing outside air into the fan-equipped work clothes from the fan as cooling air; discharging the cooled air taken in from the fan through the air exhaust gap; and taking some of the cooled air taken in from the fan into the flexible conduit from both ends of the flexible conduit of the collar gap securing device and discharging it from the air vent hole in the collar gap securing device in a direction that abuts against the worker's neck. [Effects of the Invention]

[0012] According to the invention of claim 1, the collar gap securing device is made of a flexible material, so it can be easily deformed to fit the worker's posture. Furthermore, when a worker wears a fan-equipped work suit with the flexible conduit hanging around their neck, an air exhaust gap is secured between the collar of the fan-equipped work suit and the worker's neck, allowing air to escape. This allows the air taken in by the fan to be exhausted through the air exhaust gap, lowering the worker's body temperature. Furthermore, some of the air taken in by the fan is drawn into the flexible conduit from both ends and is exhausted through the air vent hole in a direction that contacts the worker's neck, so the air can directly hit the worker's neck, further reducing body temperature.

[0013] According to the invention of claim 2, the collar gap securing device attached to the worker's neck ensures an air exhaust gap for air to escape between the collar of the fan-equipped workwear and the worker's neck. In this state, the fan of the fan-equipped workwear is operated, drawing in outside air as cooling air into the fan-equipped workwear, and then discharging the cooling air taken in from the fan through the air exhaust gap, thereby facilitating the circulation of cooling air and lowering the worker's body temperature.

[0014] In addition, some of the cooling air taken in by the fan is taken into the flexible conduit from both ends of the flexible conduit of the nape gap securing device and discharged from the air vent of the nape gap securing device in a direction that contacts the worker's neck, so that the cooling air directly hits the worker's nape, which is expected to have the effect of further reducing body temperature.

[0016] An embodiment of the present invention will be described below. Fig. 1 is a structural diagram of a collar gap securing device according to an embodiment of the present invention. The collar gap securing device 11 is made by processing a flexible electrical conduit 12 made of a rigid and flexible synthetic resin. The flexible electrical conduit 12 made of synthetic resin is, for example, a PF (Plastic Flexible Conduit) pipe or a CD (Combined Duct) pipe.

[0017] As shown in Figure 1, the neck gap securing device 11 is formed by cutting a flexible electrical conduit 12 made of synthetic resin to a length that can be hung around the neck of a worker and providing multiple air vent holes 13 in the flexible electrical conduit 12. Figure 1 shows a case where four air vent holes 13 are provided. The air vent holes 13 are provided so as to be positioned in a direction that will contact the worker's neck when the flexible electrical conduit 12 is hung around the worker's neck. As will be described later, the neck gap securing device 11 secures an air exhaust gap that allows air to escape between the collar of the fan-equipped work clothing and the worker's neck when the worker wears the fan-equipped work clothing with the flexible electrical conduit 12 hung around the worker's neck.

[0018] 2 is an external view showing a state in which a nape gap securing device according to an embodiment of the present invention is worn around the neck 16 of a worker. A flexible electrical conduit 12 is wrapped around the neck 16 and both sides of the chest of a worker 15 wearing plain clothes 14, and the flexible electrical conduit 12 of the nape gap securing device 11 is hung around the neck 16 of the worker 15. At this time, the flexible electrical conduit 12 is hung around the neck 16 of the worker 15 so that the air vent hole 13 of the flexible electrical conduit 12 abuts against the neck 16 of the worker 15.

[0019] With the flexible conduit 12 hung around the neck 16 of the worker 15, the worker 15 puts on the fan-equipped work suit 17 shown in FIG. 3. FIG. 3 is an external view of the fan-equipped work suit 17 as seen from the back side. As shown in FIG. 3, fans 18 are attached to the left and right sides of the back of the fan-equipped work suit 17. As will be described later, when the fans 18 are operated, outside air is drawn into the fan-equipped work suit 17 through the air intake ports of the fans 18. The power supply that drives the fans 18 is not shown, but is stored inside the fan-equipped work suit 17.

[0020] FIG. 4 is an external view showing a state in which a worker is wearing fan-equipped workwear 17 with a nape gap securing device according to an embodiment of the present invention attached to the worker's neck 16.

[0021] As shown in Figure 4, when a worker 15 wearing plain clothes 14 puts on fan-equipped workwear 17 while wearing flexible conduit 12 around the worker's neck 16, a gap is formed between the collar 19 of fan-equipped workwear 17 and the worker's neck 16 due to the flexible conduit 12. This gap is an air exhaust gap through which cooling air that is taken into fan-equipped workwear 17 from the air intake port of fan 18 when fan 18 on the back 11 of fan-equipped workwear 17 shown in Figure 3 is activated escapes.

[0022] Figure 5 is a partially cutaway external view showing the flow of cooling air through the air discharge gap between the collar 19 of the fan-equipped work suit 17 and the neck 16 of the worker 15. Figure 5 shows the flow of cooling air on the back side of the worker 15.

[0023] As shown in Figure 5, when a worker 15 wearing plain clothes 14 wraps flexible conduit 12 around his neck 16 and both sides of his chest, an air exhaust gap is formed on the back side of the worker 15 between the collar 19 of the fan-equipped work suit 17 and the neck 16 of the worker 15. Most of the cooling air inside the fan-equipped work suit 17 escapes through this air exhaust gap. That is, most of the cooling air inside the fan-equipped work suit 17 passes through the top of the flexible conduit 12 and escapes in the direction of the head of the worker 15, as indicated by arrow A, facilitating the circulation of cooling air taken in from fan 18 and lowering the worker's body temperature.

[0024] Meanwhile, part of the cooling air taken in by the fan 18 is taken into the flexible conduit 12 from both ends of the flexible conduit 12 and is discharged directly to the neck 16 of the worker 15 through the air vent 13 of the flexible conduit 12. This allows the cooling air to directly hit the worker's neck 16, which is expected to have the effect of further lowering body temperature.

[0025] Fig. 6 is a flowchart showing the steps of a cooling air circulating method according to an embodiment of the present invention. First, the nape gap securing device according to the embodiment of the present invention shown in Fig. 1 is worn around the neck (S1). That is, as shown in Fig. 2, flexible conduit 12 is wrapped around the neck 16 and both sides of the chest of worker 15 wearing plain clothes 14, and flexible conduit 12 of nape gap securing device 11 is hung around neck 16 of worker 15. At this time, flexible conduit 12 is hung around neck 16 of worker 15 so that air vent hole 13 of flexible conduit 12 abuts against neck 16 of worker 15.

[0026] Next, the worker puts on the fan-equipped work suit 17 with the nape clearance securing device attached to the worker's neck (S2). That is, as shown in Figure 4, the worker 15 puts on the fan-equipped work suit 17 with the flexible electrical conduit 12 attached to the worker's neck 16.

[0027] Then, the collar gap securing device secures an air discharge gap between the collar of the fan-equipped work suit and the worker's neck (S3). That is, when the worker 15 wears the fan-equipped work suit 17 with the flexible conduit 12 attached to the worker's neck 16, an air discharge gap through which cooling air can escape is formed between the collar 19 of the fan-equipped work suit 17 and the worker's neck 16, so the collar gap securing device 11 can secure an air discharge gap between the collar 19 of the fan-equipped work suit 17 and the worker's neck 16.

[0028] With the air exhaust gap secured in step S3, the fan of the fan-equipped work suit is operated (S4), and outside air is drawn into the fan-equipped work suit as cooling air (S5), and the cooling air drawn in from the fan is discharged through the air exhaust gap (S6).

[0029] Then, a portion of the cooling air taken in from the fan is taken into the flexible conduit from both ends of the flexible conduit of the nape gap securing device and discharged from the air vent of the nape gap securing device in a direction that contacts the worker's neck (S7).

[0030] That is, when the fan 18 of the fan-equipped work suit 17 is operated, outside air is drawn into the fan-equipped work suit 17 through the air intake port of the fan 18, and the drawn-in outside air passes through the fan-equipped work suit 17 as cooled air and is discharged from the air discharge gap secured by the collar gap securing device 11 between the collar 19 of the fan-equipped work suit 17 and the neck 16 of the worker 15.

[0031] Most of the cooling air inside the fan-equipped work suit 17 escapes through the air exhaust gap. For example, at the back of the worker 15, as shown in Figure 5, most of the cooling air inside the fan-equipped work suit 17 passes through the top of the flexible conduit 12 and escapes toward the head of the worker 15 as indicated by arrow A, allowing for easy circulation of the cooling air and lowering the worker's body temperature.

[0032] Meanwhile, part of the cooling air taken in by the fan 18 is taken into the flexible conduit 12 from both ends of the flexible conduit 12 and is discharged directly to the neck 16 of the worker 15 through the air vent 13 of the flexible conduit 12. This allows the cooling air to directly hit the worker's neck 16, which is expected to have the effect of further lowering body temperature.

[0033] Although several embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the invention and its equivalents as defined in the claims.
