Description

clothes

The present invention relates to clothes to which a blower can be attached and detached.

There is known a clothes to which a blower can be attached and detached (see, for example, JP-A-2005-54299). In such clothes, the body of the wearer of the clothes can be cooled by the outside air being delivered into the clothes by the blower.

In the above-mentioned clothes, the air taken in from the outside by the fan cools the body while flowing between the wearer's body and the clothes and cools the body, and flows out from the air outlet part provided on the collar or the cuff. For this reason, when air leaks from a portion (hem, facing, etc.) other than the air outlet portion, the cooling effect tends to be lowered.

This invention is made in view of such a situation, and makes it a subject to provide a technique which can cool a wearer's body effectively in clothes which an air blower can attach and detach.

SUMMARY OF THE INVENTION In one aspect of the present invention, a garment is provided that includes a blower, an outer surface, and a backing attached to the outer surface. The blower has an inlet and an outlet. The outer surface is provided with a mounting portion. The air blower can be attached to the mounting portion in a state where the air inlet and the air outlet are disposed on the outer side and the lining side of the outer surface, respectively. An internal space is formed between the outer surface and the lining. Outside air delivered from the exhaust port by the driving of the blower can flow in the internal space. And when the outside air is sent out to the internal space with the air flow rate Q (cubic meter per minute: m ³ / min) by the air blower in the non-wearing state of the internal space, the air flow rate Q and the pressure P of the internal space (Pascal: Pa) and it is configured so as to satisfy the relationship of P ≧ 1.1Q ^2.

According to the clothes of the present embodiment, the outside air delivered to the internal space between the outer fabric and the lining by the blower expands the lining away from the outer fabric (that is, increases the distance between the outer fabric and the lining) A suitable internal pressure P can be obtained. This makes it easier for at least a portion of the backing to come into contact with the wearer's body (or underwear), so that the backing can absorb sweat and the sweat flowing between the outer surface and the backing can be easily evaporated. . In this case, efficient heat exchange can be performed at the contact portion between the backing and the body (or underwear) to effectively cool the wearer. The internal space has a flow rate Q and pressure P, it is more preferably configured so as to satisfy the relationship of P ≧ 1.4Q ^2, is configured so as to satisfy the relationship of P ≧ 2.0Q ² It is more preferable to be configured to satisfy the relationship of P を 満 た す 3.0Q ² . In this case, the backing can be further inflated, so that a wider area of backing can be more reliably contacted by the wearer's body.

SUMMARY OF THE INVENTION In one aspect of the present invention, a garment is provided that includes a blower, an outer surface, and a backing attached to the outer surface. The blower has an inlet and an outlet. The outer surface is provided with a mounting portion. The air blower can be attached to the mounting portion in a state where the air inlet and the air outlet are disposed on the outer side and the lining side of the outer surface, respectively. An internal space is formed between the outer surface and the lining. This clothing is such that the pressure in the internal space when outside air is delivered to the internal space by the air blower in a non-wearing state is at least 5 pascals in any air volume within the air volume range where the air blower can blow air. It is configured.

According to the garment of this aspect, the pressure of the internal space is increased to at least 5 Pascals by the outside air delivered between the outer fabric and the lining by the blower to expand the lining away from the outer fabric (that is, between the outer fabric and the lining) Increase the distance between). This makes it easier for at least a portion of the backing to come into contact with the wearer's body (or underwear), so that the backing can absorb sweat and the sweat flowing between the outer surface and the backing can be easily evaporated. . In this case, efficient heat exchange can be performed at the contact portion between the backing and the body (or underwear) to effectively cool the wearer. Note that “the range of air volume that can be blown by the air blower” in this aspect refers to a predetermined predetermined air volume when the air volume is uniform (cannot be changed), and the air volume can be changed. In the above, the range from the minimum value to the maximum value of the air volume settable by the user's operation or by the control device. Note that the minimum value is approximately 0.4 cubic meters per minute (m ³ / min) or more, and the maximum value is approximately 2.5 cubic meters per minute, taking into account the practical restrictions on the specifications of blowers that can be removed from clothes. (M ³ / min) or less. Although it depends on the sewing, it is preferable that the pressure in the internal space be about 40.4 Pascal or less. In this case, the pressure in the internal space is too high, and the lining is excessively pressed against the body of the wearer, which can prevent the wearing feeling from being impaired.

In one aspect of the present invention, the backing may include a first area and a second area having higher permeability than the first area. According to this aspect, in the lining, the outside air delivered to the internal space flows out from the second area, which has higher air permeability than the first area, in terms of the volume capable of circulating a predetermined unit area per unit time. It is easy to configure. Therefore, it becomes possible to cool a wearer's body more effectively by selectively arranging a 2nd field corresponding to a specific part of a wearer's body.

In one embodiment of the present invention, the air permeability of the first region measured by JIS L 1096-1998 6.27 air permeability A method (Frazil method) may be in the range of 1 to 50 cc / cm ² / s. The air permeability of the first region is preferably in the range of 10 to 30 cc / cm ² / s, and more preferably in the range of 15 to 25 cc / cm ² / s. According to this aspect, the external air delivered to the internal space is allowed to flow out of the second region actively to effectively cool a specific part of the body, and also to slowly flow out of the first region to allow the body to It is possible to promote heat dissipation from a wider area and to further enhance the cool feeling. By setting the air permeability of the first area within the above range, even if the lining is not in contact with the wearer's body, heat is released from the body by the outside air flowing out to the body side through the first area. Can be promoted. In particular, when the air permeability of the first region is in the range of 10 to 30 cc / cm ² / s, at least a part of the backing is in contact with the wearer's body without increasing the air flow. Since ambient air flows sufficiently to the body through the first region, it is more reliable to realize both efficient heat exchange at the contact portion between the lining and the body (or underwear) and heat dissipation from a wide area of the body. Can effectively cool the wearer's body.

In one aspect of the present invention, the second region is made of mesh fabric, and the first region may be made of woven fabric, knitted fabric or non-woven fabric other than mesh fabric. According to this aspect, it is possible to smoothly flow the outside air from the second region configured by the mesh cloth having a higher ratio of the void.

In one aspect of the present invention, the second region may be a region of the backing that corresponds to at least one of the circumference of the wearer's neck, around the base of the arm, and the chest when the garment is worn. According to this aspect, the external air is directly applied to a portion of the body where heat is absorbed and the cooling effect of the body is considered to be high (a portion where a thick blood vessel passes immediately below the skin), thereby cooling the wearer's body more effectively. can do.

In one aspect of the present invention, the edge of the backing may be attached to the outer surface in a state in which the entire edge can not be opened to the outer surface, or in a state where a portion can be opened and closed. The “non-openable state” typically refers to a state in which the entire edge is joined to the outer surface by stitching, adhesion or the like, and the “openable / closable state” typically refers to the edge A part of the part is provided with an opening, which means that the opening can be closed by means such as a button, slide fastener, hook and loop fastener or the like. According to this aspect, in the case where the air blowing is performed by the air blower, the state in which the internal space is surrounded by the outer surface and the lining is ensured, and unnecessary air leakage from the internal space is suppressed, and the internal space is more reliably The pressure of the can be maintained. In addition, it is possible to selectively discharge the outside air from an opening formed between a part of the edge and the outer surface as needed.

In one aspect of the present invention, when the clothes are worn and external air is delivered to the interior space by the blower, the pressure of the interior space is the space formed between the backing and the wearer's body. It may be configured to be higher than the pressure. According to this aspect, the backing can be inflated well.

According to one aspect of the present invention, the garment is configured such that at least a portion of the backing adheres to the wearer's body when the blower delivers ambient air to the interior space when worn. May be According to this aspect, the backing can absorb sweat, and the external air flowing between the outer surface and the backing can further enhance the effect of evaporating the sweat.

According to one aspect of the present invention, there is provided a clothes to which a blower having an inlet and an outlet can be attached and detached. The garment comprises an outer surface and a backing attached to the outer surface. The outer material has a mounting portion to which the air blower can be attached and detached with the air inlet and the air outlet disposed on the outer side and the lining side of the outer material, respectively. Between the outer surface and the lining, an internal space is formed in which the outside air delivered from the exhaust port can flow by the driving of the air blower mounted on the mounting portion. In addition, the permeability of the backing measured by JIS L 1096-1998 6.27 air permeability A method (Frazil method) is in the range of 1 to 50 cc / cm ² / s and is larger than the air permeability of the outer layer.

In the garment of this embodiment, the air permeability of the backing is set to be relatively small although it is larger than the air permeability of the outer fabric. Thereby, the external air of the internal space can be gently drained to the wearer's body side through the lining while maintaining the external air pressure of the internal space to a certain extent. Therefore, according to the garment of this embodiment, even if the lining is not in contact with the body, the heat released from the entire body is promoted by the ambient air flowing slowly from the entire lining, effectively cooling the wearer. can do. Also, when at least a portion of the backing is in contact with the wearer's body, the sweat can be absorbed by the portion and the sweat can be evaporated by the external air flowing between the outer surface and the backing. In this case, efficient heat exchange can cool the wearer effectively.

The air permeability of the backing in this embodiment is preferably in the range of 10 to 30 cc / cm ² / s, and more preferably in the range of 15 to 25 cc / cm ² / s. In addition, the lining is selectively provided with a vent having higher permeability than the upper limit of the above range (it may be an opening covered with a fabric with a higher permeability or a through hole). May be By setting the air permeability of the first area within the above range, even if the lining is not in contact with the wearer's body, heat is released from the body by the outside air flowing out to the body side through the first area. Can be promoted. In particular, when the air permeability of the first region is in the range of 10 to 30 cc / cm ² / s, at least a part of the backing is in contact with the wearer's body without increasing the air flow. Since ambient air flows sufficiently to the body through the first region, it is more reliable to realize both efficient heat exchange at the contact portion between the lining and the body (or underwear) and heat dissipation from a wide area of the body. Can effectively cool the wearer's body.

According to one aspect of the present invention, there is provided a clothes to which a blower having an inlet and an outlet can be attached and detached. The garment comprises an outer surface and a backing attached to the outer surface. The outer material has a mounting portion to which the air blower can be attached and detached with the air inlet and the air outlet disposed on the outer side and the lining side of the outer material, respectively. Between the outer surface and the lining, an internal space is formed in which the outside air delivered from the exhaust port can flow by the driving of the air blower mounted on the mounting portion. The air permeability of the lining is greater than the air permeability of the outer fabric. Further, in the lining, the area of the first region surrounded by the joint between the outer surface and the lining is larger than the area of the second region surrounded by the joint in the outer fabric.

In the clothes of this aspect, when the air permeability of the backing is set higher than the air permeability of the outer surface, the air blower is attached to the mounting portion, and when the outside air is delivered to the internal space, the outside air flows out from the lining rather than the outer surface It is easy to configure. In addition, since the area of the first region of the lining is larger than the area of the second region of the outer layer, the lining is likely to expand to the wearer's body side, and at least a part of the lining is on the wearer's body (or underwear). It becomes easy to touch. As a result, the backing is made to absorb sweat, and this perspiration is easily evaporated by the ambient air flowing between the outer surface and the backing. Also, the ambient air that has flowed through the backing can promote heat dissipation from the wearer's body. Thus, the wearer's body can be effectively cooled. In addition, since the swelling of the lining is larger than that of the outer material, for example, even when the outer material has a size along the body, the lining can be easily brought into contact with the body efficiently. In the present embodiment, the area of the first region is preferably 1.1 to 2 times the area of the second region. In this case, the lining can be effectively inflated to the body side.

In addition, the bonding | joining method of the outer_surface and lining in this aspect is not specifically limited, For example, stitching | suture and adhesion are included. The first region and the second region do not have to be joined along the entire circumference, and a portion not connected to a part of the outer periphery (an opening for communicating the internal space with the outside) is selectively provided. It may be done. Also, such openings may be occludable by means such as, for example, buttons, slide fasteners, hook and loop fasteners and the like.

As a result, the fan attachment portion 212 (front material 2) is disposed on the front side of the flange portion 87. Further, the user opens the slide fastener 302 (see FIG. 2) of the backing 3 and attaches the ring member 89 to the main body 81 through the opening 301. Specifically, the ring member 89 (cylindrical portion 891) is moved to the main body portion 81 (cylindrical portion 85) until the fan attachment portion 212 (front 2) is held by the outer flange portion 87 and the inner flange portion 893. Screw in). When the fan unit 8 is attached in this manner, the exhaust port 880 is disposed between the outer surface 2 and the backing 3 so as to face the backing 3.

Thereafter, as shown in FIG. 2, the connector 911 of the cable 91 is connected to the fan unit 8 through the opening 301, and the end on the connector 913 side is pulled out of the opening 306 for the cable 91 into the lining 3. In the present embodiment, the fan unit 8 is electrically connectable to the battery holder 96 shown in FIG. The battery holder 96 has a known configuration in which a rechargeable battery 95 as a power source of the fan unit 8 can be mounted and can be electrically connected. In addition, the battery 95 of this embodiment is a known battery which can be used as a power supply of an electric tool by being attached to various electric tools (a screwdriver, a hammer drill, etc.). From the battery holder 96, a cable 961 having a connector 962 at one end is extended. The connector 911 of the cable 91 can be connected to the connector 962.

In addition, the battery holder 96 with which the battery 95 was mounted can be accommodated in the pocket 304 (refer FIG. 2). Further, the battery holder 96 can be attached to a belt or the like by an elastic clip 963 provided on the battery holder 96.

In addition, the battery holder 96 is provided with an operation button 965 for inputting an instruction to start and stop driving of the fan unit 8 (specifically, the motor 82). In the present embodiment, the battery holder 96 is also equipped with a controller (typically, a microcomputer including a CPU) that performs drive control of the motor 82 in accordance with information input through the operation button 965. . Further, in the present embodiment, the operation button 965 can also input an instruction for adjusting the air volume of the fan unit 8. Adjustment of the air volume is performed by the controller changing the rotational speed of the motor 82 in accordance with the information input from the operation button 965. In the present embodiment, the air volume of the fan unit 8 can be adjusted in two stages of 0.8 m ³ (weak) per minute and 1.4 m ³ (strong) per minute.

Hereinafter, the relationship between the jacket 1 and the air blowing by the fan unit 8 will be described. In the present embodiment, as described above, the air inlet 860 of the fan unit 8 is disposed outside the outer fabric 2, and the air outlet 880 is disposed between the outer fabric 2 and the lining 3. When the motor 82 is driven and the fan 83 is rotated, the sucked outside air flows into the housing 84 through the air inlet 860. The inflowing outside air flows out through the exhaust port 880 in the direction crossing the front and the rotation axis A1. That is, the outside air is sent between the outer material 2 and the lining 3.

With regard to garments referred to as conventional air-permeable garments, external air flows in the space between the wearer's body and the fabric of the garment (outer for non-lined garments, lining for lined garments). The main focus is on evaporating the sweat of the person and taking away heat. Therefore, by closing the end of the clothes (for example, the jacket, the hem of the pants, the front stand, the collar, the cuffs, etc.) with fasteners or squeezing it with rubber, a space where external air can flow between the body and the fabric It is common to keep the Thereby, the ease of movement at the time of wearing and the degree of freedom of the manner of wearing are easily impaired.

On the other hand, the inventors of the present embodiment constitute the outer jacket 1 of the present embodiment, focusing on the following two points different from the conventional one. One point is that the pressure of the internal space 10 is raised above atmospheric pressure by the outside air sent between the outer fabric 2 and the lining 3 by the fan unit 8 to expand the lining 3 in a direction away from the outer fabric 2 (that is, the outer fabric 2 and Increase the distance between the backing 3), make at least a part of the backing 3 contact the wearer's body and absorb the sweat, and evaporate the sweat by the ambient air flowing between the outer fabric 2 and the backing 3 That is the point. In this case, efficient heat exchange is performed at the portion of the backing 3 in contact with the body, and the wearer can obtain a cool feeling. In addition, another point is that external air is slowly drained from the internal space 10 through a relatively wide area of the lining 3 to promote heat dissipation from the body.

Based on this point of view, the inventors have found that the pressure in the internal space 10 formed between the outer fabric 2 and the lining 3 when the fan unit 8 blows air in the non-wearing outer jacket 1 (hereinafter simply referred to as An appropriate relationship between the internal pressure and the air volume of the fan unit 8 was found.

First, it is considered that the internal pressure substantially corresponds to a force (pressure loss, air flow resistance) that impedes the flow of the outside air in the internal space 10. Pressure loss is known to be proportional to the square of air volume. Therefore, the inventors have stated that a relational expression (approximate expression) such as P = K · Q ² (K is a coefficient) can be established between the internal pressure P (Pa) and the air volume Q (m ³ / min). From the point of view, the factor K was studied intensively. The coefficient K is a predetermined (dimensionless) constant (Constant).

As a result, to identify that it is preferable coefficient K is 1.1 or more, the air volume Q and pressure P is, in the case of satisfying the relationship of P ≧ 1.1Q ^2, preferably pressure P in accordance with the air volume Q, That is, it has been found that an internal pressure P can be obtained which makes it easy to bring the backing 3 into contact with the wearer's body. When air blowing is performed with a constant air flow rate Q, the internal pressure P gradually increases until the backing 3 expands to the maximum, so the internal pressure P here corresponds to the maximum internal pressure in the air flow rate Q. The coefficient K is preferably 1.4 times or more, more preferably 2.0 times or more, and still more preferably 3.0 times or more. In other words, the air volume Q and pressure P is, it is preferable to satisfy the relationship of P ≧ 1.4Q ^2, it is more preferable to satisfy the relation P ≧ 2.0Q ^2, to satisfy the relationship of P ≧ 3.0Q ² Is more preferred.

With regard to the outer jacket 1 of the present embodiment, the inventors measure air volume using a differential pressure flowmeter and blow air from the mounting opening 211 of the outer jacket 1 suspended in the non-wearing state to the internal space 10 The Then, the internal pressure (gauge pressure (pressure based on atmospheric pressure)) at this time was measured using a pressure gauge disposed between the outer fabric 2 and the lining 3 of the lower central portion (per waist region) of the back body 21. . As a result, the internal pressure when the air flow per minute 0.86 m ³ is 6.0 Pa, the internal pressure when the air flow per minute 1.16 m ³ is 8.6Pa, the internal pressure when the air flow per minute 1.63 m ³ is The internal pressure was 13.2 Pa when the air volume was 2.16 m ^{3 /} min at 13.3 Pa, and the internal pressure was 23.7 Pa when the air volume was 2.5 6 m ^{3 /} min. This result, together with the graph of the function ^{P = 1.1Q 2, P = 1.4Q} 2, P = 2.0Q 2, P = 3.0Q 2, are plotted in diamond-shaped markers in FIG. As shown in FIG. 7, according to the jacket 1 of the present embodiment, the internal pressure P and the air volume Q is satisfied the relationship of P ≧ 3.0Q ^2, the air volume Q per minute 0.8m of the fan unit 8 It can be seen that even when set to ³ (weak), a relatively high internal pressure P can be obtained.

Furthermore, the inventors also identified the relationship between the internal pressure P and the maximum distance D between the outer fabric 2 and the backing 3 by the following procedure. First, the fan unit 8 is attached to the fan attachment portion 212, the slide fastener 231 is opened, and the outer jacket 1 in a state in which the left body and the right body are separated is spread (see FIG. 2). It was placed on a generally horizontal plane (floor) with 3 at the top. Then, air is blown by the fan unit 8, and the pressure between the outer material 2 and the lining 3 at the internal pressure P specified using the pressure gauge disposed between the outer material 2 and the lining 3 at the lower center of the back body 21 (per waist). The maximum distance D between them was measured. As a result, the maximum distance D when the internal pressure P is 0.40 Pa, 0.72 Pa, 0.90 Pa, 1.09 Pa, 1.52 Pa is 3.0 cm, 5.5 cm, 8.0 cm, 13. It was 0 cm and 16.5 cm.

From this result, when the relationship between the internal pressure P and flow rate Q satisfies the relation P ≧ 1.1Q ^2, if the air volume Q is at least every minute 0.8 m ^3, generally the maximum distance D above 5.5cm is If it is considered that the relationship between the internal pressure P and the air volume Q satisfies the relationship of P ≧ 1.4Q ² , the maximum distance of approximately 8.0 cm or more if the air volume Q is at least 0.8 m ^{3 /} min. It is believed that D is obtained. Further, when the relationship between the internal pressure P and flow rate Q satisfies the relation P ≧ 2.0Q ² is the air volume Q is the maximum distance D substantially above 5.5cm of long per minute 0.6 m ³ is obtained, air flow rate It is believed that a maximum distance D of 8.0 cm or greater can be obtained if Q is 0.7 m ³ per minute. Furthermore, when the relationship between the internal pressure P and the air volume Q satisfies the relationship of P3.03.0Q ² , if the air volume Q is 0.5 m ^{3 /} min, the maximum distance D of 5.5 cm or more is obtained, and the air volume Q It is thought that a maximum distance D of 8.0 cm or more can be obtained if the is 0.6 m ³ per minute.

If the internal pressure P is the same, the distance between the outer fabric 2 and the lining 3 when the wearer actually wears the outer jacket 1 is considered to be shorter than the maximum distance D measured as described above. If the maximum distance D is at least 5.5 cm, in the case of an adult male of average figure (height and chest), part of the lining 3 (especially the area covering the back body 21) the body of the wearer It was confirmed that it could be adhered to Furthermore, if the maximum distance D is at least 8.0 cm, a wider range of the lining 3 (especially the area covering the back body 21) can be reliably adhered to the wearer's body, and also the average adult It has been confirmed that it can also be used for wearers smaller than men (smaller in height and chest). For the jacket 1 of the embodiment, as described above, the internal pressure P and the air volume Q is satisfied the relationship of P ≧ 3.0Q ^2, the air volume Q per minute 0.8 m ³ of the fan unit 8 (weak) The internal pressure P is at least 1.92 Pa even if it is set to. Therefore, since the maximum distance D is 16.5 cm or more, it is understood that the lining 3 can be sufficiently adhered to the body of the wearer, and the body of the wearer can be effectively cooled.

Further, in the outer garment 1 of the present embodiment, the lining 3 includes the main area 31 and the exhaust area 32 having higher air permeability than the main area 31. In particular, in the present embodiment, the exhaust area 32 is made of mesh cloth and the main area 31 is twill cloth, and the air permeability of the exhaust area 32 is much higher than that of the main area 31. For this reason, the outside air sent to the internal space 10 easily flows out of the exhaust region 32 and the fluidity of the external air in the internal space 10 is also secured. Therefore, the outside air flowing out of the exhaust area 32 directly cools the neck, both armpits, the back of the base of both arms, and the chest (the dovetail and its upper part), thereby giving the wearer a feeling of coolness and heat. It can effectively cool down a trapped body. Further, the external air flowing in the internal space 10 can effectively evaporate the sweat absorbed by the backing 3. Furthermore, since the main area 31 is made of a fabric capable of maintaining the internal pressure P while allowing the outside air to pass to some extent, the main area 31 passes through the area which is not in close contact with the wearer's body. It can also give the wearer a sensation of coldness by promoting heat dissipation from the body by the ambient air.

Further, in the present embodiment, the air permeability of the outer material 2 is relatively low, so that the outside air delivered to the inner space 10 is prevented from flowing out through the outer material 2. Thus, outside air can be preferentially flowed out of the exhaust region 32 and the main region 31 while maintaining the internal pressure P satisfactorily. In addition, it is also possible to cool the arm by letting the outside air flowing out of the exhaust area 32 provided near the base of the arms on both sides and the back side pass through the sleeve 25 and flow out from the cuff. In the vicinity of the cuff of the sleeve 25, an opening for exhausting the outside air may be formed.

Furthermore, in the outer jacket 1 of the present embodiment, when the slide fastener 231 of the front body 23 is fully opened and the front is worn (that is, the chest and the abdomen are not covered by the front body 23) However, the internal pressure is well maintained. Thereby, compared with the conventional so-called ventilation clothes etc., the ease of movement at the time of wear and the freedom degree of a wearing mode can be improved. Specifically, it can be worn not only in a state in which the front of the outer jacket 1 is closed, but also in a state in which the front is open, it can be used without squeezing the hem with the drawstring 29. Thereby, a feeling of oppression at the time of wearing can also be eliminated. Furthermore, in the outer jacket 1 of the present embodiment, the area of the area surrounded by the edge (suture portion) 30 in the lining 3 is approximately 1.1 times the area of the outer fabric 2 surrounded by the edge 30. The lining 3 is more easily expanded to the body side than the outer fabric 2 which affects the appearance. Therefore, the lining 3 can be efficiently inflated to the body side to make it easy to touch the body, and the appearance of the outer jacket 1 can be kept good.

The above embodiment is merely an example, and the clothes and the blower according to the present invention are not limited to the configuration of the illustrated outerwear 1 and fan unit 8.

For example, the factors (the air permeability, the fabric weight, the density, the elongation rate, the type of fiber, the type of tissue, etc.) of the outer fabric 2 and the backing 3 are mentioned as factors that affect the coefficient K described above. Therefore, it is possible not only the illustration of the above-mentioned embodiment, but as long as coefficient K is 1.1 or more, it is possible to change surface 2 and lining 3 suitably. Below, it illustrates about the characteristic which the front material 2 and the backing 3 may possess (however, it is not limited to the following examples).

As the outer material 2, chemical fibers (for example, polyester fibers, aramid fibers, polyphenylene sulfide fibers, acrylic fibers, nylon fibers, rayon fibers, acetate fibers, polyurethane fibers, polyether ester fibers, etc.), natural fibers (cotton, wool, silk, etc.) And the like) or fabrics (fibers, knits, non-woven fabrics, etc.) containing fibers composited with these. Outer layer 2 has an air permeability measured by JIS L 1096-1998 6.27 air permeability A method (Frazil method) generally in the range of 0.01 to 40 cc / cm ² / s, preferably 0.05 to 20 cc. It is in the range of / cm ² / s, more preferably in the range of 0.05 to 10 cc / cm ² / s. In addition, as illustrated in the embodiment, it is preferable that the air permeability of the outer fabric 2 is lower than the air permeability of the lining 3 (main region 31). Moreover, in order to inflate the backing 3 with as little air flow as possible, it is preferable to set the air permeability of the outer fabric 2 to a relatively low value within the above range. The basis weight of the outer fabric 2 can be adjusted to satisfy the above-mentioned air permeability, and is usually in the range of 50 to 300 g / m ² , preferably in the range of 70 to 250 g / m ² . In addition, it is preferable that a fabric excellent in water resistance and moisture permeability is adopted for the outer fabric 2.

Also for the backing 3, as in the case of the outer fabric 2, fabrics (woven fabrics, knitted fabrics, non-woven fabrics, etc.) containing chemical fibers, natural fibers, or fibers composited with these can be adopted. The permeability of the main region 31 is usually in the range of 1 to 50 cc / cm ² / s, preferably in the range of 10 to 30 cc / cm ² / s, and more preferably 15 to 25 cc / cm ² It is in the range of / s. In order to increase the internal pressure with a flow rate as small as possible and to inflate the backing 3, it is preferable to set the air permeability of the main area 31 to a relatively low value within the above range. On the other hand, it is preferable that the air permeability is not too low in order to promote heat dissipation from the body by the outside air flowing out to the body side through the main region 31. When the air permeability of the main area 31 is in the range of 10 to 30 cc / cm ² / s, at least a part of the backing 3 is in contact with the wearer's body without increasing the air flow so much. Since the outside air flows sufficiently to the body side through the main region 31, both efficient heat exchange at the contact portion between the lining 3 and the body (or underwear) and heat dissipation from a wide area of the body are achieved more reliably. Can effectively cool the wearer's body.

The exhaust area 32 may have a higher air permeability than the main area 31, and may be made of a known woven or knitted fabric such as plain weave or twill weave other than mesh fabric, or is formed of an opening not covered by fabric. May be In this case, the opening may be formed by a part of the edge 30 of the backing 3 being attached to the outer fabric 2 in an openable / closable manner. The opening can be opened and closed by, for example, a slide fastener, a surface fastener, a snap button or the like. In addition, the exhaust area 32 does not necessarily have to be provided in all of the areas facing the wearer's neck, both armpits, the back of the base of both arms, and the chest as in the above embodiment. The exhaust area 32 may be at least one or may be omitted. When the exhaust area 32 is omitted, it is preferable to increase the air permeability of the lining 3 as compared to the case where the exhaust area 32 is provided. In this case, effective cooling can be performed by promoting heat radiation from a wide area of the body by the outside air passing through the entire backing 3 (main region 31).

Further, the area ratio of the exhaust area 32 to the main area 31 may be changed as appropriate. In addition, it is known that the greater the wind speed of the wind striking the wearer, the higher the feeling of coolness. The wind speed when the fan unit 8 blows air with the same air volume increases as the area of each exhaust area 32 decreases. Therefore, in order to effectively cool the specific region of the wearer with as little air flow as possible, it is preferable that the area ratio of the exhaust area 32 to the main area 31 and the area of each exhaust area 32 be relatively small. Furthermore, by setting the air permeability of the main area 31 within the above range, the outside air delivered to the internal space 10 is also gently discharged from the main area 31 to promote heat dissipation from a wide area of the body, and a feeling of coolness It can be raised more.

Also, the basis weight of the main region 31 is usually in the range of 30 to 150 g / m ² , preferably in the range of 40 to 120 g / m ² , and more preferably in the range of 50 to 90 g / m ² is there. It is preferable that the fabric which comprises the main area | region 31 at least among the linings 3 is excellent in water absorbency and quick-drying property.

In the above embodiment, the outer jacket 1 is an upper jacket with sleeves 25, and the lining 3 covers substantially the entire inner surface of the back body 21 and the front body 23. However, the lining 3 may be attached so as to cover only the inner surface of the back body 21 or may be attached so as to cover the inner surface of the sleeve 25 in addition to the back body 21 and the front body 23. In the relationship between the area of the area surrounded by the suture portion (the edge 30) of the outer material 2 and the lining 3 and the area of the lining 3 in the outer material 2, the area of the lining 3 is usually The area of the region may be at least 1 time, preferably 1.1 to 2 times. The method of attaching the backing 3 to the outer surface 2 is not limited to the suture, and adhesion with an adhesive, ultrasonic welding, or the like may be employed.

The garment of the present invention can also be suitably realized as, for example, a hooded upper garment, a sleeveless upper garment (so-called vest), a so-called coverall in which the upper garment and the pants are connected, or a trousers. With regard to the upper coat and the coverall, the lining 3 is preferably attached so as to cover at least a part (preferably half or more, more preferably the entire area) of the back body 21 of the outer fabric 2. The use of clothes is not particularly limited, and may be realized as work clothes, sportswear, leisure wear, fire fighting clothes, protective clothes, surgical clothes, and the like.

Here, with reference to FIG. 8 and FIG. 9, the vest | best 100 which concerns on one modification of the outerwear 1 is demonstrated. As shown in FIGS. 8 and 9, the vest 100 is provided with an outer fabric 200 and a lining 300, as with the jacket 1 (see FIG. 2). However, unlike the outerwear 1, the outer fabric 200 has only the back body 21 and the front body 23, and does not have a sleeve. In the lining 300, the entire edge 30 is sewn to the outer fabric 2 so as to cover the entire back body 21 and the entire front body 23, as in the case of the outer jacket 1. However, unlike the jacket 1, the lining 300 does not have an exhaust area 32 corresponding to the back side of the base of both arms. These exhaust areas 32 in the jacket 1 are provided for delivering the outside air into the sleeve 25, whereas in the sleeveless vest 100 the need is low. The other configuration of the vest 100 is the same as that of the jacket 1.

In addition, as mentioned above, the conventional structure which maintains the space where external air can flow between the body and the fabric by closing the end of the clothes (hems and cuffs of the jacket, etc.) with fasteners or squeezing with rubber etc. So it was difficult to achieve a sleeveless jacket like the Best 100. On the other hand, by utilizing the pressure of the internal space 10 between the backing 300 and the outer fabric 200, the body of the wearer can be effectively cooled even in the vest 100. In addition, the vest 100 can further reduce the feeling of pressure when worn and improve the ease of movement by having no sleeve.

In the following, an outer jacket 102 and a vest 104 as a further modification of the outer jacket 1, and an outer jacket 109 (all not shown) as comparative examples for the outer jacket 1, the outer jacket 102 and the vest 104 will be described.

The outer jacket 102 is configured as a front-opened long sleeve upper coat having the same configuration as the outer jacket 1 shown in FIG. That is, the outer jacket 102 has an outer surface including a back body, a front body and sleeves, and a lining including a main area and an exhaust area attached so as to cover the entire front and back body, and the fan unit 8 includes It is configured to be removable. However, the characteristics of the outer fabric of the outerwear 102 are different from those of the outer fabric 2 of the outerwear 1. Specifically, the outer fabric of the outer jacket 102 is a cotton fabric having a warp density of 120 / 2.54 cm and a weft density of 110 / 2.54 cm. Moreover, the fabric weight of the outer material is 155 g / m ² . Furthermore, the air permeability measured by JIS L 1096-1998 6.27 air permeability A method (Frazil method) is 6.9 cc / cm ² / s. The type, density, basis weight and air permeability of the backing (main area and exhaust area) of the outer jacket 102 are the same as the backing 3 of the outer jacket 1.

The vest 104 is configured as a sleeveless upper garment having the same configuration as the vest 100 shown in FIG. That is, the vest 104 includes an outer surface including a back and front body, and a lining including a main area and an exhaust area, attached so as to cover the entire front and back body, and the fan unit 8 is detachable. It is configured. A point similar to the vest 100 is that no corresponding exhaust area is provided at the back side of the base of both arms. The outer surface of the vest 104 is a polyester fabric having a thread density of 249 / 2.54 cm and a weft density of 103 / 2.54 cm. Also, the basis weight of the outer material is 103 g / m ² . Furthermore, the air permeability measured by JIS L 1096-1998 6.27 air permeability A method (Frazil method) is 0.3 cc / cm ² / s. The type, density, basis weight and air permeability of the backing (main area and exhaust area) of the vest 104 are the same as the backing 3 of the jacket 1.

The outer jacket 109 according to the comparative example is configured as a front sleeve long sleeve upper coat, and includes an outer surface including a back body, a front body and a sleeve, and a lining attached to the outer surface, and the fan unit 8 is detachable It is configured. However, the lining of the outer jacket 109 is joined to the outer surface so as to cover only the back body. The type, density, basis weight and air permeability of the outer jacket 109 are the same as those of the outer jacket 2 of the outer jacket 1. The lining of the outer jacket 109 is a polyester mesh fabric, and the air permeability thereof measured by JIS L 1096-1998 6.27 air permeability A method (Frazil method) is 170.7 cc / cm ² / s. In addition, the lining of the outer jacket 109 is entirely formed of a mesh fabric with very high air permeability, and includes a plurality of areas with different air permeability, such as the main area 31 and the exhaust area 32 of the outer jacket 1 Not in.

The inventors measure the air volume while using the differential pressure flowmeter for the outer coat 102 and the vest 104 according to the modification of the outer coat 1 and the outer coat 109 according to the comparative example as well as the outer coat 1. The air was blown to the internal space formed between the outer surface and the backing by the fan unit 8 and the internal pressure (gauge pressure) at this time was measured.

For the jacket 102, the internal pressure when the air flow per minute 0.69 m ³ is 4.4Pa, when the internal pressure is 6.3Pa when the air flow per minute 1.16 m ^3, air volume per minute 1.58 m ³ the internal pressure 9.9Pa, the internal pressure when the air flow per minute 1.94 M ³ is 15.6Pa, the internal pressure when the air flow per minute 2.35M ³ was 20.5Pa.

For the best 104, the internal pressure in the case of min 1.16 m ³ air volume is 8.2Pa, the internal pressure when the air flow per minute 1.61M ³ is 12.7Pa, air volume when the min 1.97M ³ The internal pressure was 16.1 Pa, the internal pressure was 20.0 Pa when the air volume was 2.32 m ^{3 /} min, and the internal pressure was 23.5 Pa when the air volume was 2.5 4 m ^{3 /} min.

For the jacket 109, the internal pressure when the air flow per minute 0.52 m ³ is 0.7 Pa, when the internal pressure is 1.0Pa when the air flow per minute 1.15 m ^3, air volume per minute 1.70 m ³ the internal pressure 0.6 Pa, the internal pressure when the air flow per minute 2.03M ³ is 0.5 Pa, the internal pressure when the air flow per minute 2.48M ³ was 0.2 Pa.

These results, the function ^{P = 1.1Q 2, P = 1.4Q} 2, P = 2.0Q 2, P = 3.0Q 2 graphs, and, in the measurement results together with the jacket 1 described above, FIG. 10 It is plotted on. As shown in FIG. 10, similar to the jacket 1 of the present embodiment, both for the jacket 102 and vest 104, the internal pressure P and flow rate Q satisfy the relationship of P ≧ 3.0Q ^2. From this, it can be seen that even in the jacket 102 and the vest 104, a relatively high internal pressure P can be obtained even when the air flow rate Q of the fan unit 8 is set to 0.8 m ³ (weak) per minute. Therefore, in the outer jacket 102 and the vest 104 as well as the outer jacket 1, the lining expands in the direction away from the outer layer according to the driving of the fan unit 8 to contact the wearer's body, thereby achieving efficient heat exchange. can do. In addition, the air flowing slowly through the lining can effectively promote heat dissipation from the wearer's body.

On the other hand, regarding the jacket 109 of the comparative example, the internal pressure does not increase even if the air volume is increased. More specifically, in fact the air volume range from min 0.52 m ³ the measurement was made up every minute 2.48M ^3, the internal pressure is 1 Pa at most, approximately 1 Pa or less as a whole It is flat. This is because the air permeability of the backing is as high as 170.7 cc / cm ² / s, and outside air delivered to the inner space easily passes through the backing. In addition, if the air permeability of the lining exceeds 50 cc / cm ² / s, the outside air delivered to the internal space will easily pass through the lining and it will be difficult to sufficiently increase the internal pressure as described above. The preferable upper limit of the air permeability of the backing (main region when including the main region and the exhaust region) is 50 cc / cm ² / s. As described above, in the outer jacket 109 according to the comparative example, even if air is blown by the fan unit 8, the internal pressure does not increase sufficiently, so the lining is not easily expanded in the direction away from the outer surface. In addition, outside air delivered from the fan unit 8 to the interior space can easily pass through the lining to the wearer's body in the vicinity of the exhaust port 880, so it is difficult for the outside air to flow throughout the interior space. Therefore, it is difficult for the jacket 109 to exert effects such as the jacket 1, the jacket 102, and the vest 104.

The configuration of the fan unit 8 may be changed as appropriate. For example, a smaller and higher-power brushless motor may be employed as the motor 82. The diameter of the fan 83 and the number of blades 831 may be changed. With the change, the air volume of the fan unit 8 may also change. The air volume of the fan unit 8 does not have to be adjustable in two stages. That is, the air volume of the fan unit 8 (the number of revolutions of the motor 82) may be constant, adjustable in three or more stages, or steplessly adjustable. From the viewpoint of more reliably achieving the internal pressure to fully inflate the lining 3, it is preferable that the air volume of the fan unit 8 can be set to 0.5 m ^{3 /} min or more, and 0.8 m ^{3 /} min It is more preferable that the setting can be made above. The instruction to adjust the air volume may be input through an operation member (such as a dial) other than the operation button 965, or may be disposed in an operation unit provided separately from the battery holder 96. . Further, a controller that performs drive control of the motor 82 (air volume control of the fan 83) may be disposed in the fan unit 8 instead of the battery holder 96.

The fan unit 8 may have a configuration in which a plurality of fans 83 are accommodated in one housing 84. In this case, a plurality of motors 82 may be provided corresponding to the number of fans 83. That is, the blower according to the present invention may include at least one fan, at least one motor, and at least one fan and at least one motor, and may be provided with a detachable housing on the outer surface.

Moreover, the attachment method with respect to the front material 2 of the fan unit 8 is not restricted to the example of the said embodiment. For example, one of the housing 84 (cylindrical portion 85) and the ring member 89 may be provided with a flexible locking piece, and the other may be provided with a recess in which the locking piece can be locked. In this case, the ring member 89 is fitted to the housing 84 in the direction of the rotation axis A1, and the locking piece is locked in the recess to complete the mounting. Alternatively, an L-shaped guide groove may be provided on the outer peripheral surface of the housing 84 (cylindrical portion 85), and a protrusion capable of engaging with the guide groove may be provided on the inner peripheral surface of the ring member 89. In this case, the ring member 89 is fitted to the housing 84 in the direction of the rotation axis A1 in a state where the protrusion is disposed in the guide groove, and is further rotated in the circumferential direction to complete the attachment. Further, the attachment position (fan attachment portion 212) of the fan unit 8 may be provided on the front body 23 instead of the back body 21. Further, the housing 84 may be separated into two parts in the direction of the rotation axis A2, and these two parts may be engaged in a state in which the mounting portion 212 is held.

The mounting position of the fan unit 8 and the mountable number may be changed as appropriate. For example, the fan unit 8 may be removable from the front. The number of mountable fan units 8 may be one or three or more.
