[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 52-65654 [Patent Document 2] Japanese Utility Model Application Publication No. 52-65655 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional wearable blower, the inlet pipe is connected to the front side of the case and extends upward, so when the case is worn around a person's waist, the inlet pipe is located in front of the person and gets in the way.

[0005] To provide a wearable fan that is unlikely to get in the way of a person when worn by the person. [Means for solving the problem]

[0006] A wearable blower according to one aspect of the present invention includes a waist bag that can be worn around a person's waist, and a fan. The waist bag has a bag portion that can come into contact with the person's waist.

[0007] The bag portion is provided with an exhaust port that opens in a direction including an upward component or inward, and a mounting hole, and the inward direction is preferably the direction in which the bag portion comes into contact with a person. The mounting hole can be configured to open in a direction including at least one of a downward direction and an outward direction. The outward direction is the opposite direction to the inward direction. In this case, the fan can be fixed to the periphery of the mounting hole of the bag portion and exposed from the mounting hole, and the fan can be driven to introduce air into the bag portion and exhaust it from the exhaust port.

[0008] In the case of the wearable blower of this type, the bag portion is provided with an attachment hole that opens in a direction that includes at least one of a downward direction and an outward direction. The fan is fixed to the periphery of the attachment hole and is exposed from the attachment hole. Therefore, when the waist bag is worn around a person's waist, the fan that draws air into the bag portion does not get in the way of the person.

[0009] Alternatively, the bag section may be provided with an exhaust port that opens in a direction including an upward component or inward, and an intake port, and the intake port may be configured to open in a direction including at least one of a downward and an outward component. In this case, the fan is housed in the bag section and faces the intake port, and the fan is driven to blow air from the intake port into the bag. The air can be introduced into the compartment and exhausted through the exhaust port.

[0010] In the case of a wearable blower of this type, the bag portion is simply provided with an air intake port that opens in a direction that includes at least one of the downward and outward directions, so that when the waist bag is worn around a person's waist, the air intake port for taking in air into the bag portion does not get in the way of the person.

[0011] The mounting hole may open downward or in an oblique direction that includes a downward and outward component, in which case the fan can be configured to be exposed downward or in an oblique direction from the mounting hole.

[0012] The bag portion may have an upper portion having an inner end portion on an inward direction, and the exhaust port may be provided at the inner end portion of the upper portion.

[0013] The wearable fan of any of the above aspects may further include a reinforcing portion. The reinforcing portion may have a communication hole. The communication hole may extend through the reinforcing portion. The reinforcing portion may be fixed to the bag portion such that the communication hole communicates with the exhaust port.

[0014] When the exhaust port is provided at the inner end of the upper part of the bag part, the reinforcing part can be fixed to the inner end of the upper part and extend along the inner end. In this case, the reinforcing part may or may not have a communication hole.

[0015] The inner edge of the upper part of the bag portion may be curved in an outwardly convex arc shape. The reinforcing portion may be curved in an arc shape along the inner edge.

[0016] Any of the above-described wearable blowers may further include a battery electrically connected to the fan. The battery may be housed within the bag and positioned outwardly relative to the inner end of the upper portion. Alternatively, the battery may be housed within the bag and positioned along the inner portion.

[0017] The exhaust ports are provided at least at each end of the inner end of the upper part of the bag portion, and can be configured to be positioned on both sides of a person's waist when the waist bag is worn around the person's waist.

[0018] Any of the above exhaust ports may be in the form of a mesh. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, a first embodiment, a second embodiment, and their design variations of the present invention will be described. Note that the components of the embodiments and design variations described below can be combined with each other as long as they are not inconsistent. In addition, the materials, shapes, dimensions, numbers, arrangements, etc. constituting the components of the mounted fan in each aspect of the embodiments and design variations described below are merely examples, and the design can be changed as desired as long as the same functions can be realized. EXAMPLES

[0021] Hereinafter, the wearable fan D1 according to a first embodiment of the present invention and a number of other embodiments including a design modification thereof will be described with reference to FIGS. 1A to 6. FIGS. 1A to 3 show the wearable fan D1 of the first embodiment. FIGS. 4 to 6 show a first design modification of the wearable fan D1 of the first embodiment. FIGS. 7A to 7G show a second design modification of the wearable fan D1 of the first embodiment. The wearable fan D1 of the first embodiment and the wearable fan D1 of the second design modification have substantially the same configuration, except for the outer shape of the bag section 110 of the waist bag 100 described later. FIGS. 1A to 1C, 3, 6, and 7A show the upward direction Z, the downward direction Z', the inner direction Y, and the outer direction Y'. The downward direction Z' is the opposite direction to the upward direction Z, the inner direction Y and the outer direction Y' intersect with the upward direction Z and the downward direction Z', and the outer direction Y' is the opposite direction to the inner direction Y. The upward direction Z and the downward direction Z' are also called up-down directions.

[0022] The wearable blower D1 includes a waist bag 100 (see Figs. 1A to 7G). The waist bag 100 may be any bag that can be worn around a person's waist, and may be any of a so-called waist pouch, a hip bag, and a body bag. The waist bag 100 may have a bag portion 110 and belt portions 121 and 122. The belt portions 121 and 122 extend from both ends of the bag portion 110, and have buckles at their ends. The waist bag 100 is worn around a person's waist by bringing the bag portion 110 into contact with the person's waist, wrapping the belt portions 121 and 122 around the person's waist, and connecting the buckles of the belt portions 121 and 122. Hereinafter, for convenience of explanation, the state in which the waist bag 100 is worn around a person's waist is referred to as a "worn state."

[0023] The bag section 110 has an upper section 111, an inner section 112, and an outer section 113. The upper section 111, the inner section 112, and the outer section 113 may be made of fabric made of nylon, vinyl, and / or polyester, or a high-density woven fabric with threads woven at a high density, but are not limited thereto. One or both sides of the fabric may be coated or laminated with a resin film such as polyurethane resin (for example, thermoplastic polyurethane (TPU (Thermoplastic Polyurethane)), polyester resin, polytetrafluoroethylene resin, or the like, or may be treated with PVC (polyvinyl chloride). The upper section 111, the inner section 112, and the outer section 113 are flexible.

[0024] The tear strength of the upper portion 111 and / or the outer portion 113 may be greater than the tear strength of the inner portion 112, and the tear strength of the outer portion 113 may be approximately the same as or greater than the tear strength of the upper portion 111, but is not limited to this.

[0025] The upper side portion 111 is a portion located on the upper direction Z side of the bag portion 110. The upper side portion 111 has an inner end portion 111a on the inner direction Y side, an outer end portion 111b on the outer direction Y' side, and an intermediate portion between the inner end portion 111a and the outer end portion 111b. The inner portion 112 is a portion that is placed in contact with or along the waist of a person when worn. The inner portion 112 has an upper end portion and a lower end portion. The upper end portion of the inner portion 112 is connected to the inner end portion 111a of the upper side portion 111 by sewing or bonding, and the inner portion 112 hangs down from the inner end portion 111a of the upper side portion 111. The height position of the lower end portion of the inner portion 112 in the up-down direction is located lower than the outer end portion 111b of the upper side portion 111. The outer portion 113 connects the outer end portion 111b of the upper side portion 111 and the lower end portion of the inner portion 112. The outer portion 113 has an upper end and a lower end. The upper end of the outer portion 113 is connected to the outer end 111b of the upper portion 111 by sewing or gluing, etc. The lower end of the outer portion 113 is connected to the lower end of the inner portion 112 by sewing or gluing, etc.

[0026] The upper portion 111 can be made substantially U-shaped in plan view (see FIG. 1A and FIG. 7D). In this case, the inner end 111a may be curved in an arc shape so as to fit the waist of a person when worn, and the outer end 111b may also be curved in an arc shape. The upper end of the inner portion 112 is curved in an arc shape according to the shape of the inner end 111a of the upper portion 111, and the inner portion 112 itself is curved in an arc shape according to the shape of the inner end 111a of the upper portion 111 accordingly. The lower end of the inner portion 112 bulges out so that the center is convex in the downward direction Z'. The upper end of the outer portion 113 is curved in an arc shape along the outer end 111b of the upper portion 111, and the outer portion 113 itself is curved in an arc shape according to the shape of the outer end 111b of the upper portion 111 accordingly. The lower end of the outer portion 113 is shaped to fit the shape of the lower end of the inner portion 112. The center of the outer portion 113 is inclined downward in a first oblique direction including components of the downward direction Z' and the inner direction Y from the outer end 111b of the upper portion 111 to the lower end of the inner portion 112 (see Figs. 3, 6, and 7F to 7G). Note that both ends of the inner end 111a of the upper portion 111 may be arranged on both sides of a person's waist when worn, but this is not limited to this.

[0027] In another embodiment not shown, the upper portion 111, the inner portion 112, and the outer portion 113 may be substantially rectangular. In this case, the inner portion 112 hangs down from the inner end portion 111a in the downward direction Z', the vertical height position of the lower end portion of the inner portion 112 is located lower than the outer end portion 111b of the upper portion 111, and the outer portion 113 is inclined downward in the first oblique direction from the lower end portion of the inner portion 112 to the outer end portion 111b of the upper portion 111. The bag portion 110 further has a pair of side portions, and the side portions are configured to close both openings partitioned by the upper portion 111, the inner portion 112, and the outer portion 113.

[0028] At least one exhaust port 114 is provided in the upper portion 111 in any of the above embodiments (see Figs. 1A, 4, 7C, 7D, 7F and 7G). The at least one exhaust port 114 is preferably provided in the inner end 111a of the upper portion 111 and / or in the inner end 111a of the middle portion of the upper portion 111 in the inner direction Y so as to be located in the inner direction Y from the lower end of the front and / or back body of the person's upper garment in the worn state (see Figs. 1A, 7C, 7D, 7F and 7G). However, if the upper portion 111 is located in the inner direction Y from the lower end of the front and / or back body of the person's upper garment in the worn state, the exhaust port 114 may be provided at any position of the upper portion 111 (see Fig. 4). The at least one exhaust port 114 penetrates the upper portion 111 and is directed in a direction including a component in the upward direction Z (for example, a direction including a component in the upward direction Z, a direction including a component in the upward direction Z and the inward direction Y, Or, it is open in a direction including components of the upward direction Z and the outward direction Y'.

[0029] When the inner end 111a is curved in an arc, the at least one exhaust port 114 can extend in an arc along the inner end 111a. When the inner end 111a extends in a straight line, the at least one exhaust port 114 can extend in a straight line along the inner end 111a.

[0030] The at least one exhaust port 114 may be multiple (see FIGS. 1A, 4, 7C, 7D, 7F, and 7G). For example, the multiple exhaust ports 114 may be provided at least one on each end of the inner end 111a of the upper portion 111. The upper portion 111 is substantially U-shaped in a plan view, and when both ends of the inner end 111a of the upper portion 111 are positioned on both sides of a person's waist when worn, the exhaust ports 114 provided on both ends will also be positioned on both sides of the person's waist when worn.

[0031] In any of the above embodiments, an attachment hole 115 is provided in the center of the outer portion 113 (see Figs. 1C, 3, 6, and 7E). The attachment hole 115 is located on the downward direction Z' side of at least one exhaust port 114. The attachment hole 115 opens in a second oblique direction including components of the downward direction Z' and the outward direction Y'. This second oblique direction corresponds to the oblique direction in the claims.

[0032] The mounted blower D1 further includes a fan 200. The fan 200 includes a rotating blade 210, a motor (not shown), a housing 220, and a fixing device (not shown). The housing 220 includes a cylindrical portion, outer and inner guard portions, and a flange. The rotating blade 210 and the motor are held in the housing 220. A threaded portion is formed on the outer peripheral surface of the cylindrical portion. The outer diameter of the cylindrical portion is approximately the same as or slightly smaller than the diameter of the mounting hole 115. This cylindrical portion is inserted into the mounting hole 115. The flange extends from the outer peripheral surface of the cylindrical portion and abuts against the periphery of the mounting hole 115 of the outer portion 113 from the outside. The outer guard portion is a lattice formed to block the outer opening of the cylindrical portion. The inner guard portion is a lattice formed to block the inner opening of the cylindrical portion. The fixture is a cylinder with a threaded portion formed on its inner circumferential surface, which is screwed into the cylindrical portion of the housing 220 and abuts from the inside on the periphery of the mounting hole 115 of the outer portion 113. In this manner, the periphery of the mounting hole 115 is sandwiched between the flange and the fixture, whereby the fan 200 is fixed to the periphery of the mounting hole 115. In this fixed state, the outer guard portion and the flange are exposed from the mounting hole 115 in the second oblique direction. In this manner, the fan 200 is exposed from the mounting hole 115 in the second oblique direction. Meanwhile, the cylindrical portion of the fan 200, the rotor blades 210, the motor, and the fixture are housed in the bag portion 110.

[0033] The rotating blades 210 are connected to the rotating shaft of a motor directly or indirectly via a gear or the like, and are rotatable. When the motor of the fan 200 is driven and the rotating blades 210 rotate, air is introduced into the bag section 110 and discharged from at least one exhaust port 114. The motor is turned on / off by a switch (not shown).

[0034] The wearable blower D1 may further include a battery 300. The battery 300 is electrically connected to the fan 200, so that power is supplied from the battery 300 to the motor of the fan 200. The battery 300 is accommodated in the bag portion 110. For example, the battery 300 may be accommodated in a pocket that is in the middle of the upper portion 111 of the bag portion 110 and can be opened and closed by a line fastener 116. In this case, the battery 300 is disposed on the outer direction Y' side with respect to the inner end portion 111a of the upper portion 111 of the bag portion 110 (see FIG. 3). Alternatively, the battery 300 may be accommodated in a pocket provided on the inner surface of the inner portion 112 of the bag portion 110. In this case, the battery 300 is disposed along the inner portion 112 (see FIG. 6). The battery 300 can be omitted. In this case, an external battery can be used to drive the fan 200.

[0035] The wearable blower D1 may further include a reinforcing portion 400. The reinforcing portion 400 may be flexible or rigid. The reinforcing portion 400 is made of a resin plate, or the same fabric or high-density woven fabric as the upper portion 111 of the bag portion 110. The resin plate may be made of, for example, polyvinyl chloride (PVC), polypropylene, polyethylene, polycarbonate, polyethylene terephthalate, ethylene-vinyl acetate copolymer resin (EVA resin), ABS resin, or the like. The reinforcing portion 400 is fixed to an arbitrary location on the inner surface of the upper portion 111. For example, the reinforcing portion 400 may be configured to be fixed to the inner surface of the inner end portion 111a and extend along the inner end portion 111a. When the inner end 111a is curved in an arc shape, the reinforcing part 400 extends in an arc shape along the inner end 111a (see FIG. 1A, FIG. 2, and FIG. 7D), and when the inner end 111a extends in a straight line, the reinforcing part 400 may extend in a straight line along the inner end 111a. The reinforcing part 400 may have the same number of communication holes 410 as the exhaust ports 114 penetrating the reinforcing part 400. In this case, the reinforcing part 400 may be fixed to the inner end 111a of the upper part 111 so that the communication holes 410 communicate with the exhaust port 114, or may be fixed to a part other than the inner end 111a of the upper part 111. In FIG. 1A and FIG. 7D, the reinforcing part 400 is fixed to the inner end 111a of the upper part 111 so that the communication holes 410 communicate with the exhaust port 114, and extends in an arc shape along the inner end 111a. 7A to 7C and 7E to 7G, the reinforcing portion 400 is omitted. The reinforcing portion 400 can be omitted (see FIGS. 4 to 6). The communication hole 410 can also be omitted.

[0036] In the case of the wearable blower D1 as described above, mounting hole 115 is provided in bag portion 110 so as to open in the second oblique direction. Fan 200 is fixed to the periphery of mounting hole 115 and is exposed from mounting hole 115. Therefore, when worn, fan 200 for drawing air into bag portion 110 does not get in the way of a person.

[0037] Moreover, in the wearable blower D1, when worn, at least one exhaust port 114 is located on the inner side Y of the lower end of the front and / or back body of the person's upper garment, and is configured to blow air between the front and / or back body and the person's body. Therefore, no matter what type of upper garment the person is wearing, the wearable blower D1 can blow air between the front and / or back body and the person's body. In addition, when at least one exhaust port 114 is provided at each end of the inner end 111a of the upper part 111 and is positioned on both sides of the person's waist in the worn state, the wearable blower D1 can blow air discharged from the exhaust port 114 to the armpits of the person's body.

[0038] When the tear strength of upper portion 111 is greater than that of inner portion 112, upper portion 111 is flexible, thereby preventing at least one exhaust port 114 of upper portion 111 from being crushed and partially or completely blocked. When the tear strength of outer portion 113 is greater than that of inner portion 112, outer portion 113 can support fan 200 while softening the sensation of contact of inner portion 112 with a person.

[0039] Furthermore, when the reinforcing portion 400 is provided, the area around at least one exhaust port 114 of the upper portion 111 is reinforced by the reinforcing portion 400, so that the flexibility of the upper portion 111 can prevent the at least one exhaust port 114 from being crushed and partially or completely blocked. EXAMPLES

[0040] The following describes a second embodiment of the present invention and a number of other embodiments of the mounted fan D, including its design variations. 2 will be described with reference to Figs. 8 to 11. Figs. 8 to 11 show a wearable fan D2 of the second embodiment. The wearable fan D2 has the same configuration as the wearable fan D1, except that the configuration of the bag section 110' differs from that of the bag section 110 of the wearable fan D1. The differences will be described in detail below, and the description of the wearable fan D2 that overlaps with that of the wearable fan D1 will be omitted.

[0044] The upper portion 111 may be formed in a generally mountain-like shape that is convex toward the outward direction Y' (see FIG. 8). In this case, the inner end 111a of the upper portion 111 extends linearly, and the outer end 111b of the upper portion 111 is shaped along the ridgeline of the generally mountain-like shape. The lower end of the inner portion 112 and the lower end of the outer portion 113 bulge out so that their centers are convex in the downward direction Z' (see FIG. 9). The inner end of the bottom portion 117 is shaped along the lower end of the inner portion 112, and the outer end of the bottom portion 117 is shaped along the lower end of the outer portion 113 (see FIG. 10).

[0045] In another embodiment not shown, the upper portion 111, the inner portion 112, the outer portion 113, and the bottom portion 117 may be substantially rectangular. In this case, the inner portion 112 and the outer portion 113 hang down in the downward direction Z' from the inner end portion 111a and the outer end portion 111b of the upper portion 111, and the bottom portion 117 connects the lower end portion of the inner portion 112 and the lower end portion of the outer portion 113. The bag portion 110' further has a pair of side portions, and the side portions are configured to close the openings on both sides defined by the upper portion 111, the inner portion 112, the outer portion 113, and the bottom portion 117.

[0046] The mounting hole 115 is provided in the bottom side portion 117 (see FIG. 11) and / or the outer portion 113 of any of the above embodiments. The fan 200 is fixed to the periphery of the mounting hole 115, as described above. When the mounting hole 115 is provided in the bottom side portion 117, the fan 200 is exposed from the mounting hole 115 in the downward direction Z'. When the mounting hole 115 is provided in the outer portion 113, the fan 200 is exposed from the mounting hole 115 in the outward direction Y'.
