Modes for Carrying Out the Invention

[0009] [Embodiment 1] FIG. 1 is an explanatory diagram of a person wearing the air-conditioned clothing 10 seen from the back side. FIG. 2 is a view taken along arrow II in FIG. 1. FIG. 3 is an enlarged view of part III in FIG. 1. In the present embodiment, the air-conditioned clothing 10 worn by an operator engaged in electrical wiring work will be described as an example.

[0010] The air-conditioning wear 10 includes an upper garment 20, trousers 30, a blower 21, a helmet tube 22, and a trouser tube 23. The helmet tube 22 extends above the collar of the upper garment 20. The helmet tube 22 has a length reaching the head of the wearer. The trouser tube 23 extends below the hem of the upper garment 20. The blower 21 includes a first blower 211, a second blower 212, a third blower 213, and a fourth blower 214.

[0011] The upper garment 20 is an upper body of a long-sleeved work uniform having a zip fastener at the central front part. The upper garment 20 has a total of four ventilation parts near the left and right scapulas and near the left and right flanks of the wearer. The ventilation parts are openings having substantially the same shape as the intake parts of the blower 21. Each ventilation part is provided with a pocket for holding the blower 21 or a fabric for attaching a fastener provided on the blower 21, and the blower 21 is detachable.

[0012] The first blower 211 is attached to the ventilation part near the right scapula of the wearer, the second blower 212 is attached to the ventilation part near the left scapula, the third blower 213 is attached to the ventilation part near the right flank, and the fourth blower 214 is attached to the ventilation part near the left flank. When distinguishing the four ventilation parts, the ventilation part to which the first blower 211 is attached is referred to as the first ventilation part, the ventilation part to which the second blower 212 is attached is referred to as the second ventilation part, the ventilation part to which the third blower 213 is attached is referred to as the third ventilation part, and the part to which the fourth blower 214 is attached is referred to as the fourth ventilation part.

[0013] The upper garment 20 is also provided with a pocket for a battery (not shown). Each blower 21 operates by electric power supplied from a battery. Note that the battery may be provided with a switch for individually controlling the on and off of power supply to each of the four blowers 21. The battery may be provided with a button, a dial, or the like for controlling the voltage applied to the blower 21.

[0014] The trousers 30 are long trousers. The hem of the trousers 30 is accommodated inside the ankle boots type safety shoes 38. A horizontal strip-shaped net-like part 31 is provided between the knee of the wearer and the edge of the safety shoes 38. The net-like part 31 is composed of a net-like cloth with good air permeability.

[0015] In FIGS. 1 and 2, the net-like part 31 is provided so as to go around the periphery of each of the left and right lower limbs. The net-like part 31 may be provided so as to go around, for example, each of the left and right lower limbs for half a circumference. A reinforcing material may be provided on the net-like part 31, for example, in a vertical stripe shape.

[0016] A waist tool with various tools etc. attached to a thick belt is wound around the trousers 30. Note that the configurations of the tools etc. included in the waist tool are different between FIG. 1 and FIG. 2. The operator appropriately changes the configuration of the waist tool according to the daily work content.

[0017] As shown in FIG. 2, the tip of the trouser tube 23 extending from the third blower 213 is inserted into the right pocket provided at the waist of the trousers 30. Inside the right pocket, air holes formed of, for example, a net-like cloth are provided. The right pocket is an example of an insertion hole into which the tip of the trouser tube 23 can be inserted.

[0018] The trouser tube 23 passes outside the waist tool between the third blower 213 and the right pocket. Therefore, even when heavy electrical work tools etc. are included in the waist tool, there is no risk of the trouser tube 23 being crushed by the waist tool.

[0019] As shown in FIG. 3, the helmet 50 includes a headband 51, a cap body 52, and a chin strap 53. The cap body 52 is a hard shell that protects the wearer's head. A hammock (not shown) is provided inside the cap body 52. The hammock is supported by the wearer's head, and a space is secured between the cap body 52 and the wearer's head.

[0020] The headband 51 is a flat resin band with both ends attached to the hammock and exposed in a substantially U-shape from the rear of the cap body 52. The headband 51 is provided with a length adjustment mechanism (not shown). The chin strap 53 extends from the left and right sides of the cap body 52 respectively and is connected under the wearer's chin.

[0021] As shown in FIG. 3, the helmet tube 22 passes between the headband 51 and the wearer's head and extends into the cap body 52. The tip of the helmet tube 22 is preferably located between the hammock and the cap body 52. The helmet tube 22 and the headband 51 are connected by a fixture 40. Details of the structure of the fixture 40 will be described later.

[0022] FIG. 4 is an explanatory view of the upper part of the upper garment 20 seen from the inside. A first blower 211 is attached to the inner surface of the upper garment 20. In FIG. 4, the illustration of the second blower 212, the battery, and the power cable connecting the battery and the first blower is omitted. The structure of attaching the first blower 211 to the upper garment 20 is also omitted. The first blower 211 is of a centrifugal fan type and is attached to the upper garment 20 with the exhaust part facing the collar side.

[0023] One end of the helmet tube 22 is attached to the exhaust part of the first blower 211. The helmet tube 22 is a flexible tube having a flat cross-section such as an oval or an ellipse. It is desirable that the helmet tube 22 has elasticity to return to its original shape when the external force disappears even if it is temporarily crushed by an external force. Similarly, it is desirable that the helmet tube 22 has elasticity to return to its original shape when the external force disappears even if it is temporarily bent by an external force.

[0024] The helmet tube 22 may be a so-called flat tube in which a plurality of flexible tubes with circular cross-sections are fixed to each other by fusion or the like in a flat arrangement. The flat tube has the advantage of being less likely to be crushed compared to the flat tube when an external force is applied.

[0025] A coupling (not shown) is disposed between the exhaust portion of the first blower 211 and the end portion of the helmet tube 22, and the air taken in from the intake portion of the first blower 211 is configured to be sent into the helmet tube 22.

[0026] A helmet tube fixture 221 such as a hook-and-loop fastener is attached to a portion of the helmet tube 22 facing the fabric of the upper garment 20. A corresponding hook-and-loop fastener or the like is attached to the corresponding position of the upper garment 20. Therefore, when the wearer wears the upper garment 20, the helmet tube 22 naturally hangs down outside from the collar side of the upper garment 20.

[0027] Note that the helmet tube 22 may be fixed to the upper garment 20 by, for example, tying a pair of strings attached to the inner surface of the upper garment 20. The coupling that attaches the helmet tube 22 to the first blower 211 may also serve the function of the helmet tube fixture 221.

[0028] FIG. 5 is an explanatory view of the lower part of the upper garment 20 as viewed from the inside. A third blower 213 is attached to the inside of the upper garment 20. In FIG. 5, the illustration of the first blower 211, the second blower 212, the fourth blower 214, the battery, and the power cable connecting the battery and each blower 21 is omitted. The illustration of the structure for attaching the third blower 213 to the upper garment 20 is also omitted. The third blower 213 is of a centrifugal fan type and is attached to the upper garment 20 with the exhaust portion facing the hem side.

[0029] A trouser tube 23 is attached to the exhaust portion of the third blower 213. The trouser tube 23 is a flexible tube having a flat cross-section such as an oblong or elliptical shape. It is desirable that the trouser tube 23 has an elasticity to return to its original shape when the external force disappears even if it is temporarily crushed by an external force.

[0030] The trouser tube 23 may be a so-called flat tube in which a plurality of flexible tubes with circular cross-sections are fixed to each other by fusion or the like in a flat arrangement. The flat tube has the advantage of being less likely to be crushed compared to a flat tube when an external force is applied. The trouser tube 23 may be, for example, a tube with a circular or flat cross-section integrally formed with a spiral reinforcing material.

[0031] A coupling (not shown) is arranged between the exhaust part of the third blower 213 and the end of the trouser tube 23, and is configured such that the air taken in from the intake part is sent into the trouser tube 23.

[0032] At the tip of the trouser tube 23, a trouser tube fixture 231 such as a hook-and-loop fastener is attached. Inside the right pocket of the trousers 30, a paired hook-and-loop fastener or the like is attached. The person lying in bed can fix the tip of the trouser tube 23 inside the right pocket by pressing the tip of the trouser tube 23 against the inner surface of the right pocket.

[0033] Figure 6 is a perspective view of the fixture 40. Figure 7 is a view of the fixture 40 as seen in the direction of arrow VII. The fixture 40 has a tube holding part 41 and a fixing part 42 which are integrally formed. The tube holding part 41 is a substantially C-shaped columnar body with a part of one straight part of an oval removed to form an opening.

[0034] From a plane part located on the side of the tube holding part 41 opposite to the opening part, a rectangular plate-shaped pedestal part 421 projects substantially perpendicularly. One surface of the pedestal part 421 and the end surface of the tube holding part 41 form the same plane. From the end of the pedestal part 421, a substantially rectangular plate-shaped leaf spring part 422 extends obliquely towards the side surface of the tube holding part 41. The leaf spring part 422 and the tube holding part 41 are thinner than the pedestal part 421 and are more likely to undergo elastic deformation.

[0035] A substantially rectangular plate-shaped guide portion 424 extending in a direction away from the tube holding portion 41 is formed at the tip of the leaf spring portion 422. A clamping portion 423 is formed at the boundary between the leaf spring portion 422 and the guide portion 424.

[0036] FIG. 8 is an explanatory diagram for explaining the fixture 40 through which the helmet tube 22 is inserted. FIG. 8 shows a state before the fixture 40 is attached to the helmet 50. The helmet tube 22 is inserted into the tube holding portion 41. The tube holding portion 41 has a gap with the surface of the helmet tube 22 even when the helmet tube 22 is in a state of being inflated by an internal pressure, and has a dimension that allows smooth movement along the longitudinal direction of the helmet tube 22.

[0037] An outline of the usage procedure of the air-conditioning wear 10 will be described. When washing the upper garment 20 and the trousers 30, all the blowers 21 and the batteries are removed from the upper garment 20. The helmet tube 22 attached to the first blower 211 and the trouser tube 23 attached to the third blower 213 are also removed from the upper garment 20 together. The fixture 40 inserted into the helmet tube 22 is also removed.

[0038] Before wearing the air-conditioning wear 10, the wearer attaches the blower 21 and the battery to the upper garment 20. The wearer fixes the helmet tube 22 to the upper garment 20 using the helmet tube fixture 221. The wearer connects each blower 21 and the battery. Thus, the preparation for wearing is completed. Note that the above preparation may be performed by a person other than the wearer himself / herself.

[0039] The wearer wears the trousers 30, safety shoes 38, and waist tools. Since these wearing procedures have been conventionally performed, the description thereof is omitted. The wearer wears the upper garment 20 while paying attention so that the helmet tube 22 comes out outside the collar. The wearer inserts the tip of the trouser tube 23 into the right pocket of the trousers 30 and attaches the trouser tube fixture 231 to the inner surface of the right pocket.

[0040] Figure 9 is an explanatory diagram for explaining the procedure of wearing the helmet 50. In Figure 9, the illustration of the chin strap 53 is omitted, and the helmet 50 is schematically shown. The wearer attaches the fixture 40 to the helmet tube 22. Since the tube holding part 41 has a C-shaped columnar form, the wearer can easily attach the fixture 40 near the proximal end of the helmet tube 22 by inserting the helmet tube 22 through the opening part.

[0041] The wearer puts on the helmet 50 with the helmet tube 22 along the head. The wearer adjusts the helmet 50 to the correct position and connects the chin strap 53. At this stage, as described with reference to Figure 3, the tip of the helmet tube 22 is located between the hammock and the cap body 52. The fixture 40 is located near the wearer's neck muscle.

[0042] The wearer moves the fixture 40 upward and sandwiches the headband 51 between the side surface of the tube holding part 41 and the clamping part 423. At this time, due to the presence of the guide part 424, the headband 51 is smoothly inserted between the side surface of the tube holding part 41 and the clamping part 423.

[0043] The leaf spring part 422 elastically deforms in a direction in which the space between the side surface of the tube holding part 41 and the clamping part 423 is expanded. The headband 51 presses the tube holding part 41 against the wearer's head. Since the tube holding part 41 also elastically deforms to conform to the shape of the wearer's head, it is difficult to cause pain in the head. The wearer adjusts the headband 51 so that the helmet 50 is safely fixed to the head and the helmet tube 22 is not crushed by the tube holding part 41 and the wearer's own head.

[0044] The wearer moves the fixture 40 upward until the edge of the headband 51 contacts the pedestal portion 421, and then releases the hand. The headband 51 is sandwiched between the side surface of the tube holding portion 41 and the clamping portion 423, and the fixture 40 is fixed by the elasticity of the leaf spring portion 422. The length of the headband 51 is adjusted so as to be in an appropriate state with the fixture 40 attached. Thus, the wearing of the air-conditioning wear 10 is completed.

[0045] In addition, in FIG. 9, the helmet tube 22 having a length up to the vicinity of the back of the wearer's head is schematically illustrated. The helmet tube 22 may have a length up to the vicinity of the wearer's crown.

[0046] As described above, even when the internal pressure is applied to the helmet tube 22 and it is in a swollen state, there is a gap between the tube holding portion 41 and the surface of the helmet tube 22. Therefore, for example, when the wearer bends forward, the tube holding portion 41 and the helmet tube 22 automatically slide in a direction in which the exposed portion of the helmet tube 22 from the lower end of the headband 51 becomes longer.

[0047] Similarly, when the wearer looks up, the tube holding portion 41 and the helmet tube 22 automatically slide in a direction in which the exposed portion of the helmet tube 22 from the lower end of the headband 51 becomes shorter. Therefore, the helmet tube 22 is always in a state along the wearer's neck muscles and does not interfere with the wearer's movement. That is, the helmet tube 22 is held by the tube holding portion 41, and even when the wearer moves, the tip of the helmet tube 22 remains inside the helmet 50.

[0048] Next, the usage method of the air-conditioning wear 10 will be described. When it is hot, the wearer operates the power supply switch provided on the battery to start power supply to the blower 21. In the following description, the case where the wearer operates the four blowers 21 will be described as an example.

[0049] The air taken in from the intake part of the first blower 211 is supplied to the helmet tube 22. Since the first blower 211 is a centrifugal fan type suitable for generating high air pressure, air can be stably sent to the tip of the helmet tube 22. The air discharged from the tip of the helmet tube 22 passes between the cap body 52 and the wearer's head and flows out of the helmet 50. As described above, the stuffiness inside the helmet 50 is eliminated, and the wearer feels a sense of coolness on the head.

[0050] The air taken in from the intake parts of the second blower 212 and the fourth blower 214 passes between the wearer's body and the upper garment 20 and flows out through openings such as the collar, hem, and cuffs. Since the second blower 212 and the fourth blower 214 are axial fan types suitable for generating high air volume, air can be flowed around the entire upper body with a larger surface area compared to the head. The wearer also feels a sense of coolness on the upper body.

[0051] The air taken in from the intake part of the third blower 213 is supplied to the trousers tube 23. Since the third blower 213 is a centrifugal fan type suitable for generating high air pressure, air can be stably sent to the tip of the trousers tube 23. The air discharged from the tip of the trousers tube 23 enters the inside of the trousers 30 through the air hole provided inside the right pocket, passes between the wearer's lower body and the trousers 30, and flows out of the trousers 30 from the mesh part 31. The wearer also feels a sense of coolness on the lower body.

[0052] As described above, it is possible to provide the air-conditioning wear 10 that makes the wearer feel a sense of coolness throughout the body including the inside of the helmet 50 and prevents heat stroke and the like.

[0053] According to the present embodiment, it is possible to realize the air-conditioning wear 10 that gives a sense of coolness to the wearer's head using a commercially available helmet 50.

[0054] According to this embodiment, when a trouble occurs such as the helmet tube 22 getting caught somewhere during work, the helmet tube 22 is pulled out from the fixture 40 and detached, so that the air-conditioning wear 10 that can prevent the wearer from being injured can be provided.

[0055] Since the fixture 40 only sandwiches the headband 51 from below, if the helmet tube 22 is not pulled out from the fixture 40 when a trouble occurs, the fixture 40 can be detached from the headband 51, so that the air-conditioning wear 10 that can prevent the wearer from being injured can be provided.

[0056] [Modification Example 1] Since it is necessary to ensure the withstand voltage performance, the electric work helmet 50 cannot be provided with a ventilation port. However, for example, ventilation ports can be provided in helmets other than those for electric work, such as helmets for high-place work and normal work. By providing a ventilation port, for example, on the front side of the cap body 52 instead of near the top of the head corresponding to the direction in which air flows out from the tip of the helmet tube 22, the air-conditioning wear 10 that can efficiently cool the wearer's head with the air supplied from the helmet tube 22 can be provided.

[0057] [Modification Example 2] The same centrifugal fan type blower 21 as the third blower 213 may be used for the fourth blower 214, and the trouser tube 23 extending from the fourth blower 214 may be fixed to the left pocket of the trousers 30 or any pocket provided with air holes formed of a net-like cloth. For example, by fixing the trouser tube 23 to the left pocket of the trousers 30, the air-conditioning wear 10 that can make the right foot and the left foot feel the same degree of coolness can be provided. In addition, the total number of blowers 21 may be five or more, and the axial flow fan type blowers 21 for blowing air into the upper garment 20 may be increased. The type of the blower 21 attached to each ventilation part may be replaceable by the user as appropriate.

[0058] [Modification Example 3] The tube holding part 41 may be cylindrical without an opening on its side surface. The wearer can insert the tube holding part 41 from the tip of the helmet tube 22 and place the fixture 40 at an appropriate position.

[0059] [Modification Example 4] The fixture 40 and the vicinity of the base end of the helmet tube 22 may be connected by an anti-drop string. It is desirable that the anti-drop string be set to a length such that it does not sag much when the fixture 40 is fixed to the headband 51. When providing the anti-drop string, it is not necessary to remove the fixture 40 from the helmet tube 22. An air-conditioning wear 10 in which the fixture 40 does not fall off from the helmet tube 22 can be provided.

[0060] [Modification Example 5] A large-diameter retaining portion may be provided at the tip of the helmet tube 22. In order to avoid pressing on the wearer's head, it is desirable that the retaining portion be provided in a direction along the longitudinal direction of the cross-section of the helmet tube 22. The retaining portion can provide a fixture 40 that does not fall off. The retaining portion may have, for example, a thin tip and a flared rear end, and it may be easy to insert the fixture 40 from the tip, but once inserted, the fixture 40 may have a shape that is difficult to pull out.

[0061] [Modification Example 6] FIG. 10 is an explanatory diagram for explaining the air-conditioning wear 10 of Modification Example 6. The fixing portion 42 of the fixture 40 has a shape corresponding to the edge of the rear head portion of the helmet 50, and may be directly fixed to the edge of the helmet 50 instead of the headband 51. Instead of the headband 51, a helmet 50 having a member for attaching the fixture 40 may be used.

[0062] [Modification Example 7] Two centrifugal fan type blowers 21 to which the helmet tubes 22 are attached may be provided. By using two helmet tubes 22, an air-conditioning wear 10 that can effectively prevent stuffiness inside the helmet 50 even during work in hot weather can be provided.

[0063] [Modification Example 8] A fixing part such as a surface tube is provided at the tip of the helmet tube 22 and the inner surface of the cap body 52, and the tip of the helmet tube 22 may be fixed to the inner surface of the cap body 52. It is possible to provide the air-conditioning wear 10 that holds the helmet tube 22 without using the fixture 40.

[0064] [Modification Example 9] The tip of the helmet tube 22 is airtightly sealed, and a plurality of air outlet holes may be provided on the side surface near the tip. It is possible to provide the air-conditioning wear 10 that directly blows air toward the wearer's scalp to give a cooling sensation.

[0065] [Modification Example 10] The blower 21 to which the helmet tube 22 is connected is not limited to the centrifugal fan type. Any type of blower 21 capable of generating the air pressure for sending air to the tip of the helmet tube 22 can be used. Similarly, the blower 21 to which the trouser tube 23 is connected is not limited to the centrifugal fan type. Any type of blower capable of generating the air pressure for sending air to the tip of the trouser tube 23 can be used.

[0066] For example, an axial-flow fan type blower 21 in which an axial-flow fan is housed in a housing having a flow path for sending the air discharged from the exhaust side into the tube with an appropriate air pressure may be connected to the helmet tube 22 or the trouser tube 23 and used.

[0067] Even when the air pressure on the exhaust side is high, an axial-flow fan type blower 21 having a powerful motor capable of continuously blowing air by rotating the axial-flow fan at a high speed may be used. An axial-flow fan type blower 21 having a plurality of axial-flow fans arranged in series may be used.

[0068] When an axial-flow fan is used instead of the centrifugal fan, in order to prevent air from escaping from the gap between the fan and the housing toward the intake side, it is desirable that the gap between the edge of the fan and the housing is configured to be narrow.

[0069] [Modification Example 11] FIG. 11 is an explanatory diagram for explaining the air-conditioning wear 10 of Modification Example 11. In this modification example, the helmet tube 22 passes outside the headband 51. For example, the wearer uses the fixture 40 described with reference to FIG. 6 to insert the leaf spring portion 422 between his / her occipital region and the headband 51. It is more desirable that the tip of the guide portion 424 is configured to follow the shape of the wearer's occipital region.

[0070] [Modification Example 12] A tube kit combining the helmet tube 22 and the fixture 40, a commercially available air-conditioning wear, and a blower for air-conditioning wear may be combined to realize the air-conditioning wear 10 described in Embodiment 1. The tube kit may include a coupling for connecting the helmet tube 22 and the blower for air-conditioning wear.

[0071] The tube kit may include a blower 21 that can be connected to the helmet tube 22 or that has already been connected to the helmet tube 22. When the blower 21 is included in the tube kit, it is desirable that the blower 21 has a structure that can be attached to a commercially available air-conditioning wear. The tube kit may include an adapter for attaching the blower 21 to a commercially available air-conditioning wear.

[0072] The technical features (constituent elements) described in each of the embodiments and modification examples can be combined with each other, and by combining them, new technical features can be formed. The embodiments disclosed this time should be considered as illustrative in all respects and not restrictive. The scope of the present invention is shown not by the above description but by the claims, and it is intended that all modifications within the meaning and scope equivalent to the claims are included.

[0073] The independent claims and dependent claims recited in the claims can be combined with each other in any combination regardless of the citation form. Further, the claims use, but are not limited to, a form (multi-claim form) of reciting a claim that cites two or more other claims. A form of reciting a multi-claim (multi-multi-claim) that cites at least one multi-claim may also be used.
