Description

[Technical field]

[0001] The present invention relates to a cooling garment for cooling the body of a wearer. [Background technology]

[0002] 2. Description of the Related Art Conventionally, air-conditioned clothing and cooling clothing that cool the body by using fans and cooling agents have been proposed for the purpose of preventing heatstroke and a decrease in work efficiency of workers in hot environments.

[0003] For example, work clothes have been disclosed that have openings on both sides of the clothes, and a ventilation fan is provided facing these openings, and by driving the ventilation fan driven by a portable power source, outside air is taken into the clothes and discharged from the cuffs or around the neck to cool the clothes, allowing the wearer to work comfortably in a hot environment (Patent Document 1).

[0004] Also disclosed is a vest-type work garment made of nylon mesh material with cooling function, in which a storage pocket on the back fabric can store cooling material for cooling the back, and a storage pocket on the front fabric can store cooling material for cooling the underarms (Patent Document 2).

[0005] Furthermore, a cooling garment has been proposed in which an axial flow fan having an air intake port for taking in outside air and an air outlet port for blowing air into the garment is attached to an attachment port provided on the back of the garment, an ice pack is stored in a pocket provided above the attachment port, and the outside air blown into the garment is cooled by the ice pack, and the cooled air is circulated inside the garment and exhausted from an exhaust passage provided at the collar of the garment (Patent Document 3). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] No. 3198778 publication [Patent Document 2] Patent No. 3655835 [Patent Document 3] Patent No. 6233674 Summary of the Invention [Problem to be solved by the invention]

[0007] Conventional air-conditioned clothing and cooling clothing mainly use axial fans in which air flows from the intake to the exhaust along the fan's rotating axis. Air-conditioned clothing that has axial fans on the sides, back, etc., continuously blows strong air onto specific parts of the wearer's body, which can cause discomfort and fatigue to the wearer when worn for long periods of time. In addition, high-volume axial fans that enhance the cooling effect are noisy and can interfere with conversation, and the air-conditioned or cooled clothing can become inflated with air, interfering with work.

[0008] In conventional cooling clothing that uses ice packs and is worn inside work clothes or air-conditioned clothing, when ventilation inside the clothing is insufficient, the humidity inside the clothing increases and underwear that has become wet from sweating becomes difficult to dry, which can make the wearer feel uncomfortable.

[0009] In addition, in air-conditioned clothing that is equipped with a high-volume axial fan and uses ice packs in combination to increase the cooling effect, the cooling effect of the ice packs tends to be retained for a shorter period of time because a large amount of hot outside air is taken into the cooling clothing.

[0010] When wearing a full harness type safety belt over air-conditioned or cooled clothing, if the position of the full harness type safety belt is not taken into consideration, the weight of the accessories of the full harness type safety belt and the tightness of the belt tend to close the air flow path inside the garment, causing air to stagnate inside the garment and inhibiting the evaporation of the wearer's sweat.

[0011] Furthermore, with conventional cooling garments having pockets for containing ice packs that are sewn to a predetermined position, it was difficult to adjust the cooling area, adjust the position of the ice pack to ensure an air flow path, or adjust the relative positions of the fan and the ice pack to improve cooling efficiency. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] An embodiment of the cooling garment according to the present invention will be described with reference to Fig. 1 to Fig. 6. The present invention is not limited to the following embodiment. Of course, the following components can be omitted or added, and the shapes of the components can be modified without departing from the gist of the present invention. Note that the figures are schematic, depicting only a portion and omitting the detailed structure.

[0022] FIG. 1 is a front view of the back surface of a cooling garment according to an embodiment of the present invention, showing how it is used. The cooling garment 1 is worn inside the work clothes 60 and is provided with a cooling means for cooling the body of the wearer 50. The length of the cooling garment body 1 is such that the hem 1a is positioned above the hip bones of the wearer 50. The cooling garment 1 is composed of a rear body 3 that covers the rear side of the wearer 50, and a front body 2 that is connected to the rear body 3 and covers the front side of the wearer 50, and has armholes 32 through which the arms of the wearer 50 pass. The front body 2 is located in the placket and has a connector 4 such as a buckle that can be connected detachably.

[0023] The back body 3 is provided with a pocket section 6 consisting of a plurality of pockets. The pocket section 6 is provided in the upper center of the back body 3 and is composed of a central pocket 7 which contains a panel material 12 or ice packs 5, two upper pockets 8, 8 which partially overlap the central pocket 7 and are provided at a distance from each other at positions separated from each other by the left and right sides from the center of the back body 3, and which also contain ice packs 5, and a fan pocket 11 which is provided at a distance below the central pocket 7 and contains a small fan 20 which blows air upward. As shown in FIG. 1, a partially overlapping pocket 9 near the center and a partially overlapping pocket 10 under the arm may be provided at symmetrical positions on the left and right sides of the lower part of the back body 3.

[0024] When a panel material 12 is contained in the central pocket 7 and an ice pack 5 having a thickness of about 20 to 30 mm is contained in each of the two upper pockets 8, 8, a flow path 13 for air blown from a small fan 20 can be formed between the two upper pockets 8, 8. The air discharged upward from the small fan 20 passes through an air flow path 13 formed between the two upper pockets 8, 8 and is discharged to the outside through the collar 61 of the work clothes 60. By storing the panel material 12 in the central pocket 7, when the wearer 50 wears the cooling garment 1, wears the work clothes 60 on the outside of it, and wears the full harness type safety belt 40 on the outside of the work clothes 60, the belt 41 of the full harness type safety belt 40 and the D-ring stopper 42 located at the cross portion of the belt 41 can be supported by the panel material 12, and blockage of the flow path 13 for air blown from the small fan 20 upward toward the collar 61 of the work clothes 60 can be prevented.

[0025] When the full harness type safety belt 40 is worn on the outside of the work clothes 60 and ice packs 5 are placed in each of the upper pockets 8, 8 of the cooling garment 1, the belt 41 and D-ring stopper 42 of the full harness type safety belt 40 can be positioned so as not to overlap with the ice packs 5. As shown in Fig. 1, by placing ice packs 5 in a total of four pockets, the upper pockets 8, 8 and the lower central pockets 9, 9 on the inner surface of the cooling garment 1, the body cooling effect can be improved. When the wearer 50 does not wear the full harness type safety belt 40, the center of the back of the wearer 50 can be cooled by storing an ice pack 5 in the central pocket 7 instead of the panel material 12. Also, a structure in which neither the panel material 12 nor the ice pack 5 is stored in the central pocket 7 can be used.

[0026] As shown in FIG. 1, the cooling garment 1 is a vest worn by a person working in a high-temperature environment, and is worn inside work clothes 60 to cool the body of a wearer 50. 1, 5, and 6 show an example in which a wearer 50 wears underwear 70, wears a cooling garment 1 on the outside of the underwear, wears a work suit 60 on the outside of the underwear, and wears a full harness type safety belt 40 on the outside of the work suit 60. The wearer 50 can also wear the cooling garment 1 directly on the body without wearing underwear 70. The cooling garment 1 may be a shirt or jacket with sleeves, and a full harness type safety belt may be worn directly from the outside of the cooling garment 1 without wearing the work clothes 60.

[0027] The ice pack 5 is a roughly rectangular parallelepiped bag made of polyethylene (PE) and nylon (PA). The components of the ice pack 5 are water and a highly water-absorbent polymer, and are stored inside the bag. The ice pack 5 is stored in the pocket 6 after being frozen in a freezer. The ice pack 5 is stored in the upper pocket 8 so that the surface of the bag that contacts the body side serves as a cooling surface, and the surface that contacts the inner surface of the back body 3 serves as a heat-insulating surface. The heat-insulating surface has a thicker side portion of the bag that covers the water and the highly water-absorbent polymer than the cooling surface, ensuring heat insulation. The ice pack 5 may have a structure in which a part of the generally plate-shaped material is bent along the width direction of the body according to the posture of the body of the wearer 50, and is in close contact with the body.

[0028] FIG. 2 is a front development showing the structure of a pocket on the inner surface of a cooling garment according to one embodiment of the present invention. The main body of the cooling garment 1 is made of mesh material that is stretchable and breathable. Specifically, the garment is made of a mesh-like fabric with excellent stretchability, and anti-static thread is used for sewing. The fabric of the central pocket 7 and the pair of upper pockets 8, 8 on the left and right may be a three-dimensional mesh fabric having breathability so that the wind from the small fan 20 can pass through.

[0029] The cooling garment 1 is provided with pockets 6 capable of accommodating ice packs 5 or panel materials 12 at the upper and lower portions, symmetrically arranged on the left and right. The upper pocket portion 6 has a double pocket structure made up of a central pocket 7 sewn to the center in the width direction X of the back body 3 of the cooling garment 1 at a seam 17, and upper pockets 8, 8 arranged at least partially overlapping the central pocket 7 and provided at symmetrical positions on both sides of the center line L in the width direction of the back body 3. The upper pockets 8, 8 are made up of two upper pockets 8, 8 on the left and right sides arranged at symmetrical positions in the width direction X of the cooling garment 1, and each of the left and right upper pockets 8, 8 has a part sewn to the central pocket 7 at a seam 19 and another part sewn to the back body 3 of the cooling garment 1 at a seam 18. The lower pocket portion 6 is composed of a central pocket 9 sewn at a seam 16 toward the center in the width direction X of the cooling garment 1, and an underarm pocket 10 arranged to partially overlap the central pocket 9. The underarm pocket 10 is a pocket located under the armpit of the wearer 50 when the cooling garment 1 is worn. One part of the underarm pocket 10 is sewn to the central pocket 9 at a seam 14, and the other part is sewn to the back body 3 of the cooling garment 1 at a seam 15. Each pocket 6 is provided with closing means 31 consisting of a hook-and-loop fastener that closes the opening provided at the top in an openable and closable manner. After ice packs 5 or panel material 12 are placed in pocket 6, each opening can be detachably connected by closing means 31, preventing ice packs 5 or panel material 12 from falling out. Each pocket 6 is roughly the same size, and is sewn together so that each pocket 6 can hold ice packs 5 of the same size. Although FIG. 2 shows an embodiment in which the central pocket 7 at least partially overlaps with the two upper pockets 8, 8, the central pocket 7 and the two upper pockets 8, 8 may be of a size and arrangement in which they entirely overlap.

[0030] The panel material 12 may be a thin plate-like member made of soft resin. The panel material 12 made of soft resin is supported so as to ensure an air flow path 13 between the pocket portion 6 and the body side or underwear 70 side of the wearer 50 when it is stored in the central pocket 7, and can flexibly deform in response to the posture of the body. The soft resin is flexible, such as soft vinyl chloride or rubber sponge. As the panel material 12, it is also possible to use a material such as polycarbonate, which is less flexible than soft vinyl chloride or rubber sponge but is more capable of retaining its shape. Moreover, the panel material 12 can be formed of a honeycomb material in addition to a thin plate-like material. The honeycomb-shaped member can be constructed by forming upper and lower layers of a three-dimensional mesh fabric into a honeycomb (hexagonal) structure and connecting the upper and lower layers with a plurality of supporting threads. The panel material 12 does not easily bend due to external forces such as the belt 41 of the full harness type safety belt 40 or the D-ring fastener 42, and the like, and a flow path 13 for air blown from the small fan 20 toward the collar 61 of the work clothes 60 above can be stably secured.

[0031] FIG. 3 is an explanatory diagram showing a state in which the cooling garment provided with the small fan according to one embodiment of the present invention is used. A fan pocket 11 is attached to the back body 3, which holds a small fan 20 and has an opening at the top. The fan pocket 11 is made of a mesh material with large mesh that can take in outside air, and the small fan 20 housed in the fan pocket 11 blows air upward. 3, the fan pocket 11 is provided in the lower center portion of the rear body 3 of the cooling garment 1. It is preferable that the fan pocket 11 be provided below the central pocket 7. The fan pocket 11 is preferably made of a mesh material with larger mesh than the central pocket 7 and the upper pocket 8 so that the small fan 20 can take in air from inside the cooling garment 1. In addition, the fan pocket 11 may have a structure in which an opening is provided at a position opposite the intake port 23 or the exhaust port 24 of the centrifugal fan 22 of the small-sized fan 20 when the small-sized fan 20 is housed therein. The fan pocket 11 may have a bag- or box-like structure with an opening partially provided at the top that is large enough to blow air upwards so that the small fan 20 does not fall out of the fan pocket 11. The bag- or box-like fan pocket 11 may also have a hook-and-loop fastener that can be opened and closed to insert and remove the small fan 20. Furthermore, the fan pocket 11 may be provided at the hem portion 1a of the cooling garment 1.

[0032] 4 is an explanatory diagram showing a detailed structure of a small fan according to an embodiment of the present invention, where (a) is a front view, (b) is a side view, and (c) is a plan view. The small fan 20 includes a centrifugal fan 22 and a flat, substantially rectangular parallelepiped casing 21 that houses the centrifugal fan 22. The casing 21 is a flat, substantially rectangular parallelepiped housing that is made up of a lower end surface 21a, a flat surface 21b, and an upper end surface 21c. The casing 21 includes an inlet 23 opening in one of the flat surfaces 21b, an outlet 24 opening in the upper end surface 21c, and a front cover 25 attached at a position opposite the flat surface 21b. In the casing 21, a space for sucking air from the suction port 23 is formed between the front cover 25 and the flat surface 21b. The casing 21 and the front cover 25 are made of synthetic resin. The small fan 20 has a front cover 25 with a space between it and the centrifugal fan 22, so that when the centrifugal fan 22 comes into contact with the body or underwear 70 of the wearer 50, a space is created to take in outside air. The front cover 25 is detachably fixed to the upper part of the casing 21 by a fixing portion 26 . As the centrifugal fan 22 rotates, air Ws is sucked into the casing 21 from below or on the sides thereof via the suction port 23, and the air Wp is blown out upward from the air outlet 24. The small fan 20 can also be fixed to the fan pocket 11 by sandwiching the fan pocket 11 between the front cover 25 and the flat surface 21b of the casing 21 and inserting the fixing portion 26 between the mesh of the fan pocket 11.

[0033] The small fan 20 may be a centrifugal fan, a sirocco fan, or the like. The small fan 20 is housed in a fan pocket 11 at the bottom of the back body 3 of the cooling garment 1, and is provided below a pocket part 6 in which a cooling agent 5 or a panel material 12 is housed, so that the cooling agent 5 is located at a position where it is hit by air blown upward from a centrifugal fan 22. The small fan 20 promotes the flow of air inside the cooling garment 1, and has a flattened, roughly rectangular shape as shown in Fig. 4. The small fan 20 has a power switch 27 on the main body of the centrifugal fan 22, which functions to take in air inside the cooling garment 1 through an inlet 23 and blow air upward from an outlet 24, and is configured to be operated by receiving power from a built-in battery 29. Moreover, it is preferable that the small fan 20 is capable of promoting the evaporation of sweat from the wearer 50 cooled by the cooling agent 5, and that the strength of the wind can be adjusted in stages. The small fan 20 is portable and can be taken out of the fan pocket 11 for use. The small fan 20 can also be stored in the pocket portion 6 other than the fan pocket 11.

[0034] FIG. 5 is a plan view of the pocket portion taken along line AA of FIG. (a) to (d) show the state in which an ice pack 5 or a panel material 12 has been inserted into each pocket portion 6. After the ice pack 5 or the panel material 12 has been inserted, the openings of each pocket portion 6 can be detachably connected with a closing means 31, thereby preventing the ice pack 5 or the panel material 12 from falling out. The pocket portion 6 at the top of the cooling garment 1 has a double pocket structure consisting of a central pocket 7 sewn to the center of the cooling garment 1 in the width direction X, and two upper pockets 8, 8 arranged to partially overlap the central pocket 7 and provided at symmetrical positions on both sides of the center line L in the width direction of the back body 3. The upper pockets 8, 8 are composed of two upper pockets 8, 8 on the left and right sides arranged at symmetrical positions in the width direction X of the cooling garment 1. The back body 3 and the central pocket 7 are sewn together at a seam 17 . Each of the upper pockets 8, 8 has a portion sewn to the back body 3 at a seam 18, and another portion sewn to the central pocket 7 at a seam 19. It is preferable that antistatic thread is used for the seams 17, 18, 19 to prevent static electricity generation or build-up. 1(a) shows a state in which no panel material 12 is contained in the central pocket 7, and one ice pack 5 is contained in each of the upper pockets 8, 8, and a flow path 13 for air exhausted upward from the small fan 20 is formed between the work clothes 60 side and the wearer's underwear 70 and body side. 1(b) shows a state in which a panel material 12 is contained in the central pocket 7 and one ice pack 5 is contained in each of the upper pockets 8, 8, preventing the center of the back body 3 from entering the body and ensuring that a flow path 13 for air exhausted upward from the small fan 20 is secured between the work clothes 60 side and the underwear 70 side and body side of the wearer 50. 13(c) shows a state in which a cooling agent 5 is stored in the central pocket 7, allowing the central part of the back of the wearer 50 to be cooled. 1(d) is an example in which the central pocket 7 is placed on the outer surface of the back body 3. It shows a state in which a panel material 12 is contained in the central pocket 7 and one ice pack 5 is contained in each of the upper pockets 8, 8, which prevents the center of the back body 3 from entering the body side and reliably ensures a flow path 13 for air exhausted upward from the small fan 20 between the work clothes 60 side and the underwear 70 side and body side of the wearer 50. The ice packs 5 may be stored in both the central pocket 7 and the upper pockets 8, 8. In this way, the cooling garment 1 can change the number of ice packs 5 according to the working environment, working posture, and the like.

[0035] FIG. 6 is a plan view of the pocket portion taken along line BB of FIG. (a) and (b) show the state in which an ice pack 5 is inserted into each pocket portion 6. After the ice pack 5 is inserted, the insertion and removal openings of each pocket portion 6 can be detachably connected with a closing means 31, thereby preventing the ice pack 5 from falling out. The pocket portion 6 at the bottom of the cooling garment 1 is composed of a central pocket 9 sewn toward the center of the width direction X of the back body 3, and an underarm pocket 10 arranged to partially overlap the central pocket 9. The central pocket 9 is sewn to the back body 3 at a seam 16 . The underarm pocket 10 is a pocket located under the armpit when the wearer 50 is wearing the cooling garment 1. One portion of the underarm pocket 10 is sewn to the back body 3 at a seam 15, and the other portion is sewn to the central pocket 9 at a seam 14. 13(a) shows a state in which a cooling agent 5 is stored in a pocket 9 near the center, and the center side of the lower back of a wearer 50 can be cooled. 1(b) shows a state in which a cooling agent 5 is stored in the underarm pocket 10, allowing the underarm of a wearer 50 to be cooled. In addition, ice packs 5 may be stored in both the central pocket 9 and the underarm pocket 10, or neither the central pocket 9 nor the underarm pocket 10 may store ice packs 5. Also, the cooling garment 1 may be provided with either the central pocket 9 or the underarm pocket 10, or may have neither.

[0036] Since the pocket portion 6 for holding the ice pack 5 has a partially overlapping pocket structure, the wearer 50 can fine-tune the position of the ice pack 5 on the inner side of the cooling garment 1 by changing the pocket portion 6 for holding the ice pack 5, forming a flow path 13 for the air discharged upward from the small fan 20, and fine-tuning the position of the ice pack 5 to a position where it is hit by cool air.

[0037] The small fan 20 is equipped with an ON-OFF control unit 29 that operates the motor 33 of the small fan 20 intermittently at any of the set values ​​of temperature, humidity, time, etc. In Fig. 4, an example is shown in which the ON-OFF control unit 29 is built into the small fan 20, but a structure in which the ON-OFF control unit 29 is provided outside the small fan 20 is also possible. For example, the ON-OFF control unit 29 may be configured with an electronic circuit that turns the power ON when the temperature or humidity detected by a temperature sensor or humidity sensor (not shown) attached to the cooling garment 1 exceeds a set value, and turns the power OFF when the temperature or humidity falls below the set value. The ON-OFF control unit 29 may be built into the small fan 20, or may be provided outside the cooling garment 1 and connected to the small fan 20 by an electric cable. The set value for temperature or humidity is a temperature at which the wearer 50 wearing the cooling garment 1 can feel cool and comfortable. It is also possible to control the power supply to be switched on and off at preset time intervals.

[0038] That is, by switching the power of the small fan 20 ON and OFF at preset time intervals, the wearer 50 of the cooling garment 1 does not feel uncomfortable as when a constant amount of air is blown for a long period of time. Also, by controlling the small fan 20 to operate when the temperature or humidity of the space inside the work suit 60 reaches a set value and to stop the small fan 20 when the temperature or humidity inside the work suit 60 falls below the set value, the environment inside the cooling garment 1 for the wearer 50 can be kept always comfortable, and the battery of the small fan 20 can be made to last longer than in the case of continuous operation. The small fan 20 is prevented from causing discomfort to the wearer 50 when operated continuously for a long period of time, and the battery life can be extended.

[0039] In addition, the small fan 20 is configured with an air volume control unit 30 that can change the air volume by changing the rotation speed of the centrifugal fan 22, making it possible to change the air volume to a predetermined value at predetermined time intervals. Furthermore, feedback control is also possible so that when a temperature sensor and / or humidity sensor (not shown) installed outside or inside the small fan 20 detects a preset upper limit value, the air volume of the small fan 20 is increased via the air volume control unit 30, and when the temperature sensor and / or humidity sensor detects a preset lower limit value, the air volume of the small fan 20 is reduced. The range between the upper and lower limit values ​​of temperature or humidity is set so that the wearer 50 wearing the cooling garment 1 can feel cool and comfortable, and the air volume can be controlled to be constant within the temperature and humidity range between the upper and lower limit values.

[0040] That is, by changing the air volume of the small fan 20 at preset time intervals, the wearer 50 of the cooling garment 1 does not feel uncomfortable as when a constant air volume is blown for a long period of time. When the temperature or humidity in the space inside the work suit 60 reaches an upper limit and air blowing is required, the air volume blown from the small fan 20 is increased, and when the temperature or humidity in the work suit 60 reaches a lower limit and air blowing is not required, the air volume blown from the small fan 20 is reduced, thereby keeping the environment inside the cooling garment 1 for the wearer 50 comfortable. By using a small fan 20 with variable air volume, it is possible to suppress the decrease in the built-in battery and extend the usable time of the cooling garment 1.

[0041] As described above, according to this embodiment, the cooling garment 1 worn inside the work clothes 60 contains ice packs 5 or panel materials 12 in multiple pockets 6 provided on the back, and air supplied from the small fan 20 to the space inside the cooling garment 1 is converted into cooling air by the ice packs 5, which can be smoothly discharged to the outside of the work clothes 60 together with evaporated sweat through the air flow path 13 formed in the gap between a pair of thick upper pockets 8, 8 on the left and right sides that contain the ice packs 5, allowing the garment to be worn comfortably for long periods of time. [Industrial Applicability]

[0042] The present invention is not limited to the above-described embodiment, and various modifications can be made to the configuration without departing from the spirit and scope of the present invention. [Explanation of symbols]
