Description

[Technical Field]

[0001] The present invention relates to a wearable fan. [Background technology]

[0002] The following Patent Documents 1 and 2 describe conventional wearable fans. The wearable fan described in Patent Document 1 includes a ring-shaped case, an inlet pipe, a fan, and an outlet pipe. The case is a hollow annular body that can be worn around a person's waist and is provided with multiple connection holes. The inlet pipe is connected to the front side of the case. The outlet pipe is connected to one of the connection holes in the case. The fan is provided within the case. When the fan rotates, air is introduced into the case through the inlet pipe and is blown through the outlet pipe to areas where the person sweats. The wearable fan described in Patent Document 2 omits the outlet pipe from the wearable fan described in Patent Document 1, and instead uses the connection hole on the case as an exhaust port, from which air is sent between the person's skin and underwear.

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

[0008] In this type of wearable fan, the bag portion is provided with a mounting hole that opens in a direction that includes at least one of a downward and an outward direction. The fan is fixed to the periphery of the mounting hole and is exposed through the mounting 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 portion 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 component and an outward component. In this case, the fan is housed in the bag portion and faces the intake port, and when the fan is driven, air is drawn from the intake port into the bag. It is possible to configure the air to be introduced into the compartment and then discharged from the exhaust port.

[0010] In the case of a wearable blower of this type, the bag portion is simply provided with an air intake that opens in a direction that includes at least one of a downward and an outward direction component, so when the waist bag is worn around a person's waist, the air intake 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 obliquely from the mounting hole.

[0012] The bag portion may have an upper portion having an inner edge facing inward, and the exhaust port may be provided at the inner edge 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 pass through the reinforcing portion. The reinforcing portion may be fixed to the bag portion so that the communication hole communicates with the exhaust port.

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

[0015] The inner edge of the upper part of the bag portion may be curved in an arc shape that is convex outward. 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 outward from the inner edge 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 one on 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 the 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 explanation of the drawings]

[0020] Below, we will explain Example 1, Example 2, and their design variations of the present invention. Please note that the components of the examples and design variations described below can be combined with each other as long as they are not inconsistent. Furthermore, the materials, shapes, dimensions, numbers, and arrangements of the components of the wearable fan in each aspect of the examples and design variations described below are merely examples, and any design changes can be made as long as the same functions can be achieved. [Example]

[0021] A wearable fan D1 according to multiple embodiments of the present invention, including a first embodiment and its design variations, will be described below 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 variation of the wearable fan D1 of the first embodiment. FIGS. 7A to 7G show a second design variation 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 variation have substantially the same configuration, except for the outer shape of the bag portion 110 of the waist bag 100, which will be described later. FIGS. 1A to 1C, 3, 6, and 7A show an upward direction Z, a downward direction Z', an inward direction Y, and an outward direction Y'. The downward direction Z' is the opposite direction to the upward direction Z, and the inward direction Y and the outward direction Y' intersect with the upward direction Z and the downward direction Z', and the outward direction Y' is the opposite direction to the inward 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 waist pouch, a hip bag, and a body bag. The waist bag 100 may include 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. For ease of explanation, the state in which the waist bag 100 is worn around a person's waist will be referred to as the "worn state."

[0023] The bag portion 110 has an upper portion 111, an inner portion 112, and an outer portion 113. The upper portion 111, the inner portion 112, and the outer portion 113 may be made of fabric such as nylon, vinyl, and / or polyester, or a high-density woven fabric with threads woven at a high density, but are not limited to these. One or both sides of the fabric may be coated or laminated with a resin film such as polyurethane resin (e.g., thermoplastic polyurethane (TPU)), polyester resin, or polytetrafluoroethylene resin, or may be treated with PVC (polyvinyl chloride). The upper portion 111, the inner portion 112, and the outer portion 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 portion 111 is a portion located on the upward Z side of the bag portion 110. The upper portion 111 has an inner end portion 111a on the inward Y side, an outer end portion 111b on the outward 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 abuts against or is positioned 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 portion 111 by sewing or bonding, and the inner portion 112 hangs down from the inner end portion 111a of the upper portion 111. The lower end portion of the inner portion 112 is located lower in the vertical direction than the outer end portion 111b of the upper portion 111. The outer portion 113 connects the outer end portion 111b of the upper portion 111 to 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 may be substantially U-shaped in plan view (see FIGS. 1A and 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 accordingly, 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. 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 according to the shape of the outer end 111b of the upper portion 111, and accordingly, 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. 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 in the downward direction Z' and the inward 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 the person's waist when worn, but this is not limitative.

[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 in the downward direction Z' from the inner end portion 111a, 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 portion 111, and the outer portion 113 slopes 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 defined 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 of 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 a portion of the inner end 111a of the upper portion 111 and / or the inner end 111a of the middle portion of the upper portion 111 in the inward direction Y so as to be located in the inward direction Y from the lower end of the front and / or back body of the person's upper garment when worn (see FIGS. 1A, 7C, 7D, 7F, and 7G). However, if the upper portion 111 is located in the inward direction Y from the lower end of the front and / or back body of the person's upper garment when worn, the at least one 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 oriented in a direction including a component in the upward direction Z (for example, a direction including components in the upward direction Z, 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 may extend in an arc along the inner end 111a. When the inner end 111a extends linearly, the at least one exhaust port 114 may extend linearly along the inner end 111a.

[0030] The at least one exhaust port 114 may be replaced by a plurality of exhaust ports 114 (see FIGS. 1A, 4, 7C, 7D, 7F, and 7G). For example, the plurality of 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 the ends of the inner end 111a of the upper portion 111 are positioned on either side of a person's waist when worn, the exhaust ports 114 provided on these ends will also be positioned on either side 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 that includes components in the downward direction Z' and the outward direction Y'. This second oblique direction corresponds to the oblique direction in the claims.

[0032] The wearable blower D1 further includes a fan 200. The fan 200 includes a rotating impeller 210, a motor (not shown), a housing 220, and a fixture (not shown). The housing 220 includes a cylindrical portion, outer and inner guard portions, and a flange. The rotating impeller 210 and the motor are held within 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 in 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 thread formed on its inner circumferential surface, which screws into the cylindrical portion of the housing 220 and abuts from the inside against the periphery of the mounting hole 115 in the outer portion 113. In this manner, the periphery of the mounting hole 115 is sandwiched between the flange and the fixture, thereby fixing the fan 200 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 rotating blades 210, the motor, and the fixture are housed within the bag portion 110.

[0033] The rotating blades 210 are rotatably connected to the rotating shaft of the motor directly or indirectly via a gear or the like. 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 and off by a switch (not shown).

[0034] The wearable fan D1 may further include a battery 300. The battery 300 is electrically connected to the fan 200, thereby supplying power to the motor of the fan 200. The battery 300 is housed within the bag portion 110. For example, the battery 300 may be housed in a pocket that is openable and closable by a fastener 116 in the middle of the upper portion 111 of the bag portion 110. In this case, the battery 300 is disposed on the outward direction Y' side relative to the inner end 111a of the upper portion 111 of the bag portion 110 (see FIG. 3). Alternatively, the battery 300 may be housed 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 fan 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 any location on the inner surface of the upper portion 111. For example, the reinforcing portion 400 may 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 portion 400 extends in an arc shape along the inner end 111a (see FIGS. 1A, 2, and 7D). When the inner end 111a extends linearly, the reinforcing portion 400 preferably extends linearly along the inner end 111a. The reinforcing portion 400 may be configured to have the same number of communication holes 410 as the number of exhaust ports 114 penetrating the reinforcing portion 400. In this case, the reinforcing portion 400 may be fixed to the inner end 111a of the upper portion 111 so that the communication holes 410 communicate with the exhaust ports 114, or may be fixed to a portion of the upper portion 111 other than the inner end 111a. Note that in FIGS. 1A and 7D, the reinforcing portion 400 is fixed to the inner end 111a of the upper portion 111 so that the communication holes 410 communicate with the exhaust ports 114, and extends in an arc shape along the inner end 111a. 7A to 7C and 7E to 7G, the reinforcing portion 400 is not shown. 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 fan D1 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 the device is worn, fan 200, which draws air into bag portion 110, does not get in the way of a person.

[0037] Furthermore, when the wearable fan D1 is worn, at least one exhaust port 114 is located inward Y from 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 fan D1 can blow air between the front and / or back body and the person's body. Furthermore, 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 when worn, the wearable fan 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 the tear strength 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 the tear strength of inner portion 112, outer portion 113 can support fan 200 while softening the sensation of inner portion 112 coming into contact 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. [Example]

[0040] Hereinafter, a wearable fan D according to several embodiments of the present invention, including Example 2 and its design variations, will be described. 2 will be described with reference to Figures 8 to 11. Figures 8 to 11 show a wearable fan D2 of Example 2. The wearable fan D2 has the same configuration as the wearable fan D1 except that the configuration of the bag section 110' differs from the configuration 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. Note that Figure 11 also shows the upward direction Z, the downward direction Z', the inward direction Y, and the outward direction Y'.

[0041] The bag portion 110' has a bottom portion 117 in addition to the upper portion 111, inner portion 112, and outer portion 113 (see FIGS. 8 to 11). The bottom portion 117 may also be made of the above-mentioned fabric or high-density woven fabric, but is not limited to this.

[0042] The tear strength of the upper portion 111, the outer portion 113 and / or the bottom portion 117 may be greater than the tear strength of the inner portion 112, and the tear strength of the bottom portion 117 may be approximately the same as or greater than the tear strength of the upper portion 111 and / or the outer portion 113, but is not limited to this.

[0043] The upper portion 111 is a portion located on the upper Z side of the bag portion 110'. The inner portion 112 is a portion that abuts against the waist of a person when worn. The upper end of the inner portion 112 is connected to the inner end 111a of the upper portion 111 by sewing or gluing, etc., and the inner portion 112 hangs down from the inner end 111a of the upper portion 111. 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., and the outer portion 113 hangs down from the outer end 111b of the upper portion 111. The bottom portion 117 connects the lower end of the inner portion 112 to the lower end of the outer portion 113. The inner end of the bottom portion 117 is connected to the lower end of the inner portion 112 by sewing or gluing, etc. The outer end of the bottom portion 117 is connected to the lower end of the outer portion 113 by sewing or gluing, etc.

[0044] The upper portion 111 can 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 to follow the lower end of the inner portion 112, and the outer end of the bottom portion 117 is shaped to follow 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, respectively, 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, which are configured to close 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. As described above, the fan 200 is fixed to the periphery of the mounting hole 115. 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′.

[0047] Like the wearable fan D1, the wearable fan D2 may further include a battery 300 and / or a reinforcing part 400, but is not limited to this. The battery 300 and / or the reinforcing part 400 may also be omitted from the wearable fan D2.

[0048] In the case of the wearable blower D2 described above, mounting holes 115 are provided in the bag portion 110' so as to open downward Z' and / or outward Y'. The fan 200 is fixed to the periphery of the mounting holes 115 and is exposed from the mounting holes 115.

In the former case, the upper portion 111, the inner portion 112, and the outer portion 113 may be made as described above except that they are made of molded resin or the like. In the latter case, the upper portion 111, the inner portion 112, the outer portion 113, and the bottom portion 117 may be made as described above except that they are made of molded resin or the like.

[0054] Although the bag of the present invention is described as having mounting holes, it may be provided with at least one air intake port instead of the mounting holes. In this case, the air intake port should open in a direction that includes at least one of a downward and an outward direction component, and the entire fan should be housed within the bag of the present invention and positioned so as to face the at least one air intake port.

[0055] The at least one vent hole of the present invention may be provided in the inner portion of the bag portion rather than in the upper portion of the bag portion. In this case, the vent hole penetrates the inner portion and opens inward. Of course, the vent hole of the present invention may be provided in both the upper portion and the inner portion of the bag portion. Furthermore, the at least one vent hole of the present invention may be mesh-shaped. For example, the upper portion and / or part or all of the inner portion of the bag portion may be made of mesh fabric, and the mesh fabric portion may serve as the vent hole. Alternatively, the vent hole may be configured to have a through-hole penetrating the upper portion and / or inner portion of the bag portion and a mesh fabric closing the through-hole.

[0056] The reinforcing portion of the present invention may be provided not only at the inner end of the upper part of the bag portion, but also at any part of the bag portion that needs to be reinforced. The reinforcing portions may be provided on the inner and middle portions of the bag, on the inner and outer edges of the upper portion of the bag, or on the entire upper portion of the bag. The reinforcing portions may also be provided on the inner, outer and / or bottom portions of the bag instead of or in addition to the upper portion of the bag.

[0057] The waist bag of the present invention may be provided with a hook, instead of a belt part, that is connected to any of the bag parts described above and that can be hung from a belt loop or the like of a person's underwear. In this case, the hook is hung from the belt loop or the like, so that the waist bag is worn around the person's waist.

[0058] The present invention requires at least one fan. In other words, the present invention can have one or more fans. When there are multiple fans, the number of mounting holes 115 can also be multiple, depending on the number of fans 200. In this case, as described above, the fans 200 can be configured to be mounted in the mounting holes 115, respectively. Alternatively, multiple fans can be housed in the bag portion, and at least one air intake port can be provided instead of a mounting hole.

[0059] The inward direction of the present invention may be the direction in which the bag portion of the waist bag comes into contact with a person when the waist bag of the present invention is worn around the waist of the person, and the outward direction of the present invention may be the opposite direction to the inward direction of the present invention.
