Title: Air-conditioned clothing for use with helmet

Description:
TECHNICAL FIELD 
     The present invention relates to an air-conditioned clothing for use with a helmet that can cool the body by generating an air flow approximately in parallel with the body or underwear surface and that can circulate the air inside a helmet by sending the air into the helmet when the helmet is worn. 
     BACKGROUND ART 
     Recently, there has been utilized an air-conditioned clothing which can evaporate the sweat coming out from the body by generating a large flow of outer air that is approximately in parallel with the body or underwear surface. The detail description of the principal and the structure of such air-conditioned clothing are described in the Patent Literature 1, for example. Many of those who wear such air-conditioned clothings also wear helmets. In such case, the humidity in the body area can be resolved by wearing the air-conditioned clothing but the humidity in the head area caused by wearing a helmet cannot be resolved. 
     Recently, there also has been utilized a device for adding a fanning function to a regular work helmet which fulfills the safety regulation. According to such device, a fan is attached at the outside edge of a helmet so as to send the outer air which is taken in by the fan inside the helmet through an intake pipe.

     SUMMARY OF INVENTION 
     Problem to be Solved by the Invention 
     However, such device for adding the fanning function to a work helmet has serious functional problems as described below. First, since the device is directly attached to a helmet, a large fan, in terms of weight, cannot be used. Therefore, a large amount of air cannot be sent inside the helmet and the humidity in the head area cannot be efficiently resolved. Secondly, since the intake pipe is provided in a space between the helmet and the head, the cross-section area of the intake pipe cannot be large. Therefore, the air flow rate needs to be set to a high rate to send a large amount of air inside the helmet in order to efficiently circulate the air in the helmet. However, since the power consumption is proportional to the square of the air flow rate, if the air flow rate is set to a high rate, the battery will be used up quickly. 
     The present invention was made in view of the above problems and an object is to provide an air-conditioned clothing for use with a helmet which not only resolves the humidity in the body area but also efficiently resolves the humidity in the head area of a user when the helmet is worn. 
     Means for Solving the Problem 
     To solve the object described above, the present invention is An air-conditioned clothing for use with a helmet which can be used in both circumstances when the helmet is worn and when the helmet is not worn, including: an clothing main body which at least covers an upper body of a body; one or more fans which are attached to the clothing main body and which form an air flow path between the clothing main body and the body or an underwear by taking in air from outside and forcefully generate an air flow in the air flow path; an air blow-out unit which is formed between back of a neck of a user and a back collar part of the clothing main body and which blows out the air which flows through the air flow path; a guide sheet which is continuously attached to the back collar part of the clothing main body and which guides the air which blows out from the air blow-out unit to the helmet along back of the neck and back of a head of the user; and an attachment unit which is attached to an edge part of the guide sheet and which is used to attach the guide sheet to the helmet, wherein the air is made to flow through the air flow path by the fans and the flowing air evaporates sweat coming out from the body to cool the body with a heat of evaporation and in a case where the helmet is worn, the air which blows out from the air blow-out unit is guided to the helmet by the guide sheet and taken into the helmet from an air intake which is formed between an inner edge of the helmet and the head of the user in order to circulate the air inside the helmet. 
     In the air-conditioned clothing for use with helmet according to the present invention, the air is made to flow through the air flow path by the fan and the flowing air evaporates the sweat coming out from the body and cools the body of the user due to the heat of evaporation being generated when the sweat evaporates. Further, by including the guide sheet continuously attached to the back collar part of the clothing main body, the air which blows out from the air blow-out unit can be guided to the helmet along back of the neck and back of the head of the user through inner side of the guide sheet when the helmet is worn. Therefore, the air that flows through inner side of the guide sheet can evaporate the sweat coming out from back of the neck and back of the head of the user, and back of the neck and back of the head can be cooled. Further, the air which is guided to the helmet can be efficiently taken into the helmet and the air inside the helmet can be circulated. Therefore, the humidity in the head area of the user can be sufficiently resolved. 
     Effects of Invention 
     According to the air-conditioned clothing for use with helmet of the present invention, when the helmet is worn, the air that flows through inner side of the guide sheet can evaporate the sweat coming out from back of the neck and back of the head of the user, and back of the neck and back of the head can be cooled. Further, the air which is guided to the helmet can be efficiently taken in to the helmet and the air inside the helmet can be circulated. Therefore, the humidity in the head area of the user can be sufficiently resolved.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     Hereinafter, embodiments of the invention according to the present application will be described with reference to the drawings. 
     First Embodiment 
     First, the first embodiment of the present invention will be described with reference to the drawings.  FIG. 1( a )  is a schematic back view of an air-conditioned clothing for use with a helmet according to the first embodiment of the present invention,  FIG. 1( b )  is a schematic side view of the air-conditioned clothing for use with a helmet and  FIG. 1( c )  is a partial schematic cross-sectional view of the air-conditioned clothing for use with a helmet cut along the line A-A. Further,  FIG. 2  is a view used for describing the air flow in the air-conditioned clothing for use with a helmet and  FIG. 3  is a view used for describing an air blow-out unit of the air-conditioned clothing for use with a helmet. 
     The air-conditioned clothing for use with a helmet of the first embodiment can be used in both situations when a helmet is worn and when a helmet is not worn. As shown in  FIGS. 1, 2 and 3 , the air-conditioned clothing  1  for use with a helmet includes a clothing main body  10 , two fans  20  and  20 , air outlets  30 , a power unit (not shown), a power cable (not shown), an air blow-out unit  60 , a guide sheet  70  and an attachment unit  80  for attaching the guide sheet  70  to a helmet  110 . Here,  FIG. 1  shows a state where the air-conditioned clothing  1  for use with a helmet is worn with the helmet  110  and  FIGS. 2 and 3  show states where the air-conditioned clothing  1  for use with a helmet is worn but the helmet is not worn. 
     The clothing main body  10  is made of a sheet material having very little or no breathability and is formed in a shape that can cover the upper body part and the arm parts. The bottom hem part  11  of the clothing main body  10  has an elastic member such as lubber, for example, attached thereto. In such way, the bottom hem part  11  of the cloth main body  10  is made narrow so as to fit along the body or the underwear. Further, the clothing main body  10  is provided with a zip-up fastener (not shown) as an open/close unit on the front side thereof. The zip-up fastener is used to open and close the front part of the clothing main body  10  when wearing the cloth main body  10 . 
     The fans  20  generate an air flow path between the clothing main body  10  and the body or underwear by taking in the air from outside, and forcefully generate an air flow in the air flow path. The two fans  20  and  20  are respectively attached on the left and right sides at the lower part of the clothing main body  10 . Here, as for the fans  20 , fans using propellers are used. 
     Further, the clothing main body  10  is provided with an inner pocket (not shown) for carrying a power unit inside thereof. The power unit is for supplying power to the two fans  20  and  20 . As for the power unit, a power device in which a battery is embedded is used, for example. The power unit and the two fans  20  and  20  are electrically connected by the power cable. 
     The air outlets  30  are for letting out the air which flows through the space (air flow path) between the clothing main body  10  and the body or underwear. In particular, the sleeve parts and the neck part of the clothing main body  10  function as the air outlets  30 . 
     The air-conditioned clothing  1  for use with a helmet of the first embodiment can also be used when the helmet is not worn and not only when the helmet is worn. In the case where the helmet is not worn, if the two fans  20  and  20  are made to operate after a user wears the clothing main body  10  and fastens the zip-up fastener, as shown in  FIG. 2 , the outer air is taken into the clothing main body  10  from the two fans  20  and  20 . Then, the air which is taken in flows upward through the air flow path approximately in parallel with the body and is let out from the neck part and the sleeve parts which are the air outlets  30 . While flowing through the air flow path, the air evaporates the sweat coming out from the body and lowers the temperature of the body surface due to the heat of evaporation being generated when the sweat evaporates. Therefore, in order to make the cooling function of the air-conditioned clothing for use with a helmet  1  function efficiently, it is necessary to make the resistance the air flowing through the air flow path receive at the air outlets  30  be small to allow a large amount of air flow approximately in parallel with the body. As a method to realize this, the clothing main body  10  is provided with a set of adjusting strings  13  for enlarging or narrowing the space between back of the neck of the user and the back collar part  12  of the clothing main body  10  as shown in  FIG. 3 . The ends of the adjusting strings  13  are attached to the inner surface of the back collar part  12  of the clothing main body  10 . By tying the set of adjusting strings  13  so as to appropriately adjust their lengths, the size of the opening formed between back of the neck and the back collar part  12  can be adjusted appropriately. Through this large opening, a large amount of air which flows through the air flow path can be blown upward. The opening formed between back of the neck and the back collar part  12  is one of the air outputs  30  and is also the air blow-out unit  60  of the present invention. 
     In a case where a user wears the air-conditioned clothing  1  for use with a helmet and carries out a regular task, the area of the air blow-out unit  60  is set to about 10 cm 2  by adjusting the lengths of the adjusting strings  13 . Further, the rotation rate of the two fans  20  and  20  is adjusted so as to take in the air inside the clothing main body  10  from outside at the rate about 20 litters/second. In such case, with respect to the air which is taken in through the two fans  20  and  20  at the rate about 20 litters/second, apart thereof is let out from the sleeve parts and the front neck part at the rate about 12 litters/second and the rest thereof is let out from the air blow-out unit  60  at the rate about 8 litters/second. 
     Many of those who wear such air-conditioned clothings  1  for use with a helmet also wear helmets. Therefore, if the air which blows out from the air blow-out unit  60  of the clothing main body  10  can be effectively taken into the helmet, the person who wears the air-conditioned clothing  1  for use with a helmet can be relieved from the humidity inside the helmet. Further, since the air which blows out flows along back of the neck, back of the neck and back of the head can also be cooled. Since the air-conditioned clothing  1  for use with a helmet of the first embodiment includes the guide sheet  70  and the attachment unit  80 , the air which blows upward from the air blow-out unit  60  of the clothing main body  10  can be taken in to the helmet along back of the neck. That is, the air-conditioned clothing  1  for use with a helmet is provided with a function to circulate the air inside the helmet. 
     Here, with respect to the air-conditioned clothing  1  for use with a helmet, it is designed so that the air which is taken in to the clothing main body  10  inflates the clothings main body  10 , and the air flow path is formed between the clothing main body  10  and the body or underwear due to the inflation of the clothing main body  10 . Therefore, especially in the back part of the clothing main body  10 , the air also flows through the part far from the body and such air does not contribute to evaporating the sweat coming out from the body. Thus, the air which blows out from the air blow-out unit  60  is not degraded in terms of temperature and humidity and is still sufficiently maintains an effective condition for evaporating the sweat coming out from the body. 
     The guide sheet  70  is for guiding the air which blows out from the air blow-out unit  60  into the helmet  110  by guiding the air along back of the neck and back of the head. One end of the guide sheet  70  is connected to the back collar part  12  of the clothing main body  10 . That is, the clothing main body  10  and the guide sheet  70  are formed as one. Actually, as shown in  FIG. 1 , the guide sheet  70  is in the shape of a hood of a raincoat or the like except the top part of the hood where covers the top of the head is removed. 
     On the other hand, the attachment unit  80  is attached to the edge part of the guide sheet  70 . The attachment unit  80  is for attaching the guide sheet  70  to the helmet  110 . Here, as shown in  FIGS. 2 and 3 , an elastic loop belt is used as the attachment unit  80 .  FIG. 4  is a schematic side view showing a user wearing a regular work helmet. As shown in  FIG. 4 , a regular work helmet  110  includes a flange  111 . As shown in  FIG. 1( b ) , the loop belt which is the attachment unit  80  is fit around the edge circumference  112  along the flange  111  of the helmet  110 . 
     By the way, as shown in  FIG. 4 , the written information  113  such as the name, the company name, the work content and the like of the person who wears the helmet  110  is usually shown on the outside surface of the helmet  110 . Such written information  113  is important in terms of safety during work and the like. In the first embodiment, the width of the belt which is the attachment unit  80  is made to be narrow as possible so as not to cover the written information  113 . In particular, the size of the belt which is the attachment unit  80  is designed so that the rate of the outer surface of the helmet  110  that is covered by the attachment unit  80  when the attachment unit  80  is attached to the helmet  110  be 20% of the entire surface of the helmet  110  at the most. 
     As described above, the air blow-out unit  60  is an opening formed between back of the neck of the user and the back collar part  12  of the clothing main body  10 , and the air which flows through the air flow path blows out toward the guide sheet  70  via the air blow-out unit  60 . In the first embodiment, since the clothing main body  10  and the guide sheet  70  are formed as one, although the position of the air blow-out unit  60  cannot be clearly specified, it can be considered that the air blow-out unit  60  is the part of the clothing main body  10  corresponding to back of the neck of the user in terms of definition. 
     Further, as shown in  FIG. 1 , the clothing main body  10  is provided with a loose section  14 , the section being formed so as to make this section of the clothing main body  10  loose, at the upper back part thereof along the section from the fans  20  to the air blow-out unit  60 . Here, as shown in  FIG. 1( a ) , the part where the loose section  14  is formed corresponds to the range extending in the up and down directions at the upper back part of the clothing main body  10 , that is, in the range from the center back part of the clothing main body  10  to the center part of the guide sheet  70 . In particular, the two sides of the loose section  14  are sewed onto the clothing main body  10  with five loosening strings  141 . In such way, when the outside air is taken into the clothing main body  10  by the fans  20 , the loose section  14  inflates toward outside of the clothing main body  10  by the air which is taken in. 
     Next, the using method of the air-conditioned clothing  1  for use with a helmet when the helmet  110  is worn will be described. 
     The user first wears the clothing main body  10  and then wears the helmet  110 . Thereafter, the user lifts up the guide sheet  70  of the air-conditioned clothing  1  for use with a helmet so as to cover back of the neck and back of the head, and fit the loop belt which is the attachment unit  80  around the edge circumference  112  of the helmet  110 . In such way, the user can easily attach the guide sheet  70  to the helmet  110 . 
     If the fans  20  and  20  are made to operate, the outer air is taken into the air flow path of the air-conditioned clothing  1  for use with a helmet from the fans  20  and  20  and flows toward the sleeve parts (air outlets  30 ) and the air blow-out unit  60 . In the first embodiment, since the clothing main body  10  is provided with the loose section  14  at the upper back part thereof along the section from the fans  20  to the air blow-out unit  60 , the loose section  14  inflates when the fans  20  and  20  are made to operate and a large amount of air can be gathered at this loose section  14 . That is, as shown in  FIG. 1( c ) , the loose section  14  becomes a wind guide path whose cross-section area is larger than the cross-section areas of other parts where the air flows. Therefore, the large amount of air gathered here can be guided to the air blow-out unit  60  from the loose section  14  as the wind guide path. Further, since the guide sheet  70  is connected to the back collar part  12  of the clothing main body  10 , the large amount of air that blows out from the air blow-out unit  60  can be efficiently guided to the helmet  110  along the guide sheet  70  and can be taken into the helmet  110  from the air intake  114  (see  FIG. 4 ) which is formed between the inner edge of the helmet  110  and the head of the user. In such way, by taking in the air inside the helmet  110 , the air inside the helmet  110  can be circulated. 
     Here, since the clothing main body  10  is provided with the loose section  14  at the upper back part thereof in the first embodiment, a sufficient area of the air blow-out unit  60  can be assured when the fans  20  and  20  are made to operate. Therefore, the air-conditioned clothing  1  for use with a helmet does not necessarily need to include the adjusting strings  13 . 
     With respect to the air-conditioned clothing for use with a helmet of the first embodiment, the air is made to flow through the air flow path by using the fans, the flowing air evaporates the sweat coming out from the body and the body of the user can be cooled due to the heat of evaporation being generated when the sweat evaporates. Further, since the guide sheet is continuously attached to the back collar part of the clothing main body, the air which blows out from the air blow-out unit can be guided to the helmet along back of the neck and back of the head of the user through inner side of the guide sheet. Therefore, the air which flows along inner side of the guide sheet can evaporate the sweat coming out from back of the neck and back of the head of the user, and back of the neck and back of the head can be cooled. Further, since the air guided to the helmet can be efficiently guided into the helmet to circulate the air inside the helmet, the humidity in the head area of the user can be sufficiently resolved. 
     Further, in the first embodiment, the clothing main body is provided with the loose section which is formed so as to make this part of the clothing main body loose at the upper back part thereof along the section from the fans to the air blow-out unit. Therefore, when the air is made to flow through the air flow path by the fans being operated, the loose section inflates and a large amount of air can be gathered at the loose section. Thus, the large amount of air gathered here can be guided to the air blow-out unit from the loose section, and the amount of air guided to the helmet can be increased. 
     Further, in the first embodiment, the rate of the outer surface of the helmet that is covered by the attachment unit when the attachment unit is attached to the helmet is 20% of the entire surface of the helmet at the most. Therefore, the written information such as the name, the company name and the like of the person who wears the helmet that is shown on the outer surface of the helmet can be avoided from being completely covered by the attachment unit and being unrecognizable by other workers. 
     In the first embodiment, a case where an elastic loop belt is used as the attachment unit is described. However, the attachment unit is not limited to the above described configuration and may have any other configuration as long as the attachment unit is attached around the edge circumference of the helmet and can be tightened around the edge circumference.  FIG. 5  is a schematic front view showing a modified example of the attachment unit of the air-conditioned clothing for use with a helmet according to the first embodiment. As shown in  FIG. 5 , the attachment unit  800  of the modified example includes a belt  810  which is attached at the edge part of the guide sheet  70  and which is approximately in parallel with the edge part and two sheet type fasteners (engaging units which engage with each other)  820  and  820  attached at two ends of the belt  810 . As for the belt  810 , a belt made of a transparent flexible polyvinyl chloride is used. Since the flexible polyvinyl chloride belt  810  fits with and tightly attaches to the surface of the helmet, the attachment unit  800  can be firmly attached to the helmet. Further, since the belt  810  is transparent, other workers can recognize the written information even if the belt  810  overlaps the written information when the attachment unit  800  is attached to the helmet. In such aspect, under normal circumstances, it is preferred that the attachment unit of the air-conditioned clothing for use with a helmet is transparent. 
     Further, as for the attachment unit, a unit which includes elastic strings attached to the edge part of the guide sheet and two hooks (engaging units which engage with each other) which are attached to the tips of the strings can also be used. In such case, by wrapping the strings around the edge circumference of the helmet and engaging the two hooks with each other, the guide sheet can be attached to the helmet. Further, as for the attachment unit, an elastic loop string which is attached to the edge part of the guide sheet can also be used. 
     Further, with respect to the modified example of the attachment unit shown in  FIG. 5 , the length of the belt of the attachment unit can be shortened. In such case, the sheet fasteners are to be attached at the positions on the sides of the helmet that face the sheet fasteners attached to the two ends of the belt in advance and by attaching the sheet fasteners at the ends of the belt to the sheet fasteners on the helmet, the guide sheet can be attached to the helmet. In such way, the length of the attachment unit does not necessarily need to have the length that goes around the edge circumference of the helmet. 
     Second Embodiment 
     Next, the air-conditioned clothing for use with a helmet according to the second embodiment of the present invention will be described.  FIG. 6( a )  is a schematic back view of the air-conditioned clothing for use with a helmet according to the second embodiment of the present invention,  FIG. 6( b )  is a schematic side view of the air-conditioned clothing for use with a helmet and  FIG. 6( c )  is a partial schematic cross-sectional view of the air-conditioned clothing for use with a helmet cut along the line B-B. Here, in the second embodiment, the same symbols are used for the parts having the same functions as those in the first embodiment and the description thereof is omitted. 
     As shown in  FIG. 6 , the air-conditioned clothing  1   a  for use with a helmet of the second embodiment includes the clothing main body  10 , two fans  20  and  20 , air outlets  30 , a power unit (not shown), a power cable (not shown), an air blow-out unit  60 , a guide sheet  70  and an attachment unit  80   a  for attaching the guide sheet  70  to a helmet  110 . Here, the clothing main body  10  is provided with the loose section  14   a  which is formed so as to make this part of the clothing main body  10  loose at the upper back part thereof along the section from the fans  20  to the air blow-out unit  60 . 
     The first aspect of the air-conditioned clothing  1   a  for use with a helmet of the second embodiment which differs from that of the first embodiment is that the cover unit having an approximately half sphere shape which is continuously attached to the edge part of the guide sheet  70  and which covers approximately the entire helmet when the helmet is worn is used as the attachment unit  80   a . Therefore, the attachment unit  80   a  and the guide sheet  70  as a whole form a hood. 
     As shown in  FIG. 6( b ) , the hood is provided with a hood adjusting string  91  at the edge part thereof for adjusting the size of the opening of the hood. After wearing the hood over the helmet  110 , the user pulls the hood adjusting string  91 . By appropriately pulling the hood adjusting string  91 , the hood can firmly fit the helmet  110  and the space between the helmet  110  and the hood can be made small. Therefore, since the amount of the air going out from the space between the helmet  110  and the hood can be reduced, the air which blows out from the air blow-out unit  60  can be efficiently taken in to the helmet  110 . Here, the hood adjusting string  91  can be omitted. 
     The second aspect of the air-conditioned clothing  1   a  for use with a helmet of the second embodiment which differs from that of the first embodiment is that the loose section  14   a  is formed by sewing an approximately rectangle shaped cloth  142  for making this section loose to the clothing main body  10 , the vertical length of the rectangle shaped cloth  142  being approximately the same as the vertical length of the loose section  14   a . Here, as for the material of the cloth  142  for making the section loose, a coarse mesh material is used. By forming the loose section  14   a  with the approximately rectangle shaped cloth  142  for making this section loose, the loose section  14   a  be in a continuously inflated state and the air flow path of the air-conditioned clothing  1   a  for use with a helmet will have a better appearance when seen from outside. 
     The air-conditioned clothing for use with a helmet of the second embodiment has the same effects and advantages as those of the air-conditioned clothing for use with a helmet of the first embodiment. 
     Other Embodiment 
     The present invention is not limited to the above described embodiments and various modifications can be carried out within the scope of the invention. 
     For example, in the above described embodiments, cases where the clothing main body is provided with two fans are described. However, the clothing main body may be provided with three or more fans in order to increase the amount of air which is to be taken into the helmet. Further, the clothing main body may also be provided with only one fan. 
     In the above described embodiments, cases where the clothing main body is formed in a shape which covers the upper body are described. However, the clothing main body can be formed in a shape that covers the upper body and the lower body, for example. Under normal circumstances, the clothing main body can be formed in any shape as long as it at least covers the upper body. 
     In the above described embodiments, cases where the air-conditioned clothing for use with a helmet is used when a helmet is worn are mainly described. However, it is needless to say that the air-conditioned clothing for use with a helmet of the present invention can be used even when a helmet is not worn. In such case, the air-conditioned clothing for use with a helmet can be worn in a state where its guide sheet and attachment unit are hung down from the back collar part. 
     INDUSTRIAL APPLICABILITY
