Description

The present invention relates to a wearable fan.

Patent Documents 1 and 2 listed below describe conventional wearable fans. The wearable fan described in Patent Document 1 comprises 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 of the case. The outlet pipe is connected to one of the connection holes in the case. The fan is provided within the case. As the fan rotates, air is introduced into the case through the inlet pipe and then 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, allowing air to be sent from the exhaust port between the person's skin and underwear.

In the conventional wearable blowers described above, the inlet pipe is connected to the front 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.

The present invention provides a wearable fan that is less likely to get in the way when worn by a person.

One aspect of the wearable air blower of the present invention comprises 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.

The bag portion is provided with an exhaust port that opens in a direction that includes an upward component or inward, and a mounting hole. 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 that includes at least one of a downward and an outward component. The outward direction is the opposite of the inward direction. In this case, the fan is fixed to the periphery of the mounting hole in the bag portion and exposed from the mounting hole. When the fan is driven, air is introduced into the bag portion and expelled from the exhaust port.

With this type of wearable air blower, the bag portion is provided with an attachment hole that opens in a direction that includes at least one of a downward and outward direction. The fan is fixed to the periphery of this 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.

Alternatively, the bag may be provided with an exhaust port that opens in a direction that includes an upward component or an inward component, and an intake port, with the intake port opening in a direction that includes at least one of a downward component and an outward component. In this case, the fan may be housed within the bag and facing the intake port, and when driven, air is introduced into the bag from the intake port and exhausted from the exhaust port.

With a wearable air 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 the downward and outward directions. Therefore, when the waist bag is worn around a person's waist, the air intake that draws air into the bag portion does not get in the way of the person.

The mounting hole may open downward or at an angle that includes both downward and outward components. In this case, the fan can be configured to be exposed downward or at an angle from the mounting hole.

The bag portion may be configured to have an upper portion. The upper portion may have an inner end portion facing inward, and the exhaust port may be provided at the inner end portion of the upper portion.

Any of the above-described wearable blowers may be configured to further include a reinforcing portion. The reinforcing portion may be configured to have a communication hole. The communication hole may preferably pass through the reinforcing portion. The reinforcing portion may be configured to be fixed to the bag portion so that the communication hole communicates with the exhaust port.

If the exhaust port is located at the inner edge of the upper part of the bag part, the reinforcing part can 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 have a communication hole.

The inner edge of the upper part of the bag portion may be configured to be curved in an arc that convexly extends outward. The reinforcing portion may be configured to be curved in an arc along the inner edge.

Any of the wearable blowers described above may further include a battery electrically connected to the fan. The battery may be housed within the bag portion and positioned outward from the inner edge of the upper portion. Alternatively, the battery may be housed within the bag portion and positioned along the inner portion.

At least one exhaust port is provided at each end of the inner edge of the upper part of the bag, and can be configured to be positioned on both sides of a person's waist when the waist bag is worn around the waist.

Any of the above exhaust ports may be mesh-type.

The following describes 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 are possible as long as the same functions can be achieved.

The wearable fan D1 according to multiple embodiments of the present invention, including Example 1 and its design variations, will be described below with reference to Figures 1A to 6. Figures 1A to 3 show the wearable fan D1 of Example 1. Figures 4 to 6 show a first design variation of the wearable fan D1 of Example 1. Figures 7A to 7G show a second design variation of the wearable fan D1 of Example 1. The wearable fan D1 of Example 1 and the wearable fan D1 of the second design variation have substantially the same configuration, except for the external shape of the bag portion 110 of the waist bag 100, which will be described later. Figures 1A to 1C, 3, 6, and 7A show the upward direction Z, the downward direction Z', the inward direction Y, and the outward direction Y'. The downward direction Z' is the opposite direction of the upward direction Z, 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 of the inward direction Y. The upward direction Z and downward direction Z' are also called the up-down direction.

The wearable blower D1 includes a waist bag 100 (see Figures 1A to 7G). The waist bag 100 may be any bag that can be worn around a person's waist, and may be a waist pouch, hip bag, or body bag. The waist bag 100 may be configured to 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 placing the bag portion 110 in 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."

The bag portion 110 has an upper portion 111, an inner portion 112, and an outer portion 113. The upper portion 111, inner portion 112, and outer portion 113 are preferably made of fabric such as nylon, vinyl, and/or polyester, or a high-density fabric with threads woven at a high density, but are not limited to this. 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, inner portion 112, and outer portion 113 are flexible.

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

The upper portion 111 is the portion located on the upward Z side of the bag portion 110. The upper portion 111 has an inner end 111a on the inward Y side, an outer end 111b on the outward Y' side, and an intermediate portion between the inner end 111a and the outer end 111b. The inner portion 112 is the portion that abuts or is positioned along the person's waist when worn. The inner portion 112 has an upper end and a lower end. The upper end of the inner portion 112 is connected to the inner end 111a of the upper portion 111 by sewing or adhesive, and the inner portion 112 hangs down from the inner end 111a of the upper portion 111. The lower end of the inner portion 112 is located lower in the vertical direction than the outer end 111b of the upper portion 111. The outer portion 113 connects the outer end 111b of the upper portion 111 to the lower end 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. The lower end of the outer portion 113 is connected to the lower end of the inner portion 112 by sewing or gluing.

The upper portion 111 may be approximately U-shaped in plan view (see Figures 1A and 7D). In this case, the inner end 111a may be curved in an arc shape so as to fit the person's waist 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 its center is convex downward in the Z' direction. 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 match the shape of the lower end of the inner portion 112. The center of the outer portion 113 slopes downward in a first oblique direction that includes 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 Figures 3, 6, and 7F-7G). Note that both ends of the inner end 111a of the upper portion 111 may be positioned on either side of the person's waist when worn, but this is not limited to this.

In another embodiment (not shown), the upper portion 111, inner portion 112, and 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 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 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 that are configured to close both openings defined by the upper portion 111, inner portion 112, and outer portion 113.

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 of the inner end 111a so as to be located in the inward direction Y of 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 of 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 location on 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, a direction including components of the upward direction Z and the outward direction Y′.

When the inner end 111a is curved in an arc, at least one exhaust port 114 can extend in an arc along the inner end 111a. When the inner end 111a extends linearly, at least one exhaust port 114 can extend linearly along the inner end 111a.

The at least one exhaust port 114 may be replaced by multiple ports (see Figures 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 generally U-shaped in a plan view, and if 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 those ends will also be positioned on either side of the person's waist when worn.

In any of the above embodiments, an attachment hole 115 is provided in the center of the outer portion 113 (see Figures 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 defined in the claims.

The wearable blower D1 further includes a fan 200. The fan 200 has a rotating impeller 210, a motor (not shown), a housing 220, and a fixing device (not shown). The housing 220 has a cylindrical portion, outer and inner guard portions, and a flange. The rotating impeller 210 and motor are held within the housing 220. A threaded portion is formed on the outer 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. A flange extends from the outer 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 against the periphery of the mounting hole 115 in the outer portion 113 from the inside. In this way, the periphery of the mounting hole 115 is clamped 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 flange are exposed from the mounting hole 115 in the second oblique direction. In this way, 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 within the bag portion 110.

The rotating blades 210 are rotatably connected to the rotating shaft of the motor either directly or indirectly via gears or the like. When the motor of the fan 200 is driven and the rotating blades 210 rotate, air is drawn into the bag section 110 and discharged through at least one exhaust port 114. The motor is turned on and off by a switch (not shown).

The wearable blower 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 in the middle of the upper portion 111 of the bag portion 110 that can be opened and closed with a wire fastener 116. 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.

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), or ABS resin. 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, the reinforcing portion 400 extends in an arc 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 and extends in an arc along the inner end 111a so that the communication holes 410 communicate with the exhaust ports 114. The reinforcing portion 400 is not shown in Figures 7A to 7C and 7E to 7G. The reinforcing portion 400 can be omitted (see Figures 4 to 6). The communication hole 410 can also be omitted.

When using the wearable blower D1 described above, a mounting hole 115 is provided in the bag portion 110 so as to open in the second diagonal direction. The fan 200 is fixed to the periphery of this mounting hole 115 and is exposed from the mounting hole 115. Therefore, when worn, the fan 200, which draws air into the bag portion 110, does not get in the way of a person.

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 designed to blow air between the front and/or back body and the person's body. Therefore, regardless of 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 underarms of the person's body.

When the tear strength of the upper portion 111 is greater than that of the inner portion 112, the flexibility of the upper portion 111 prevents at least one exhaust port 114 in the upper portion 111 from being crushed and partially or completely blocked. When the tear strength of the outer portion 113 is greater than that of the inner portion 112, the outer portion 113 supports the fan 200 while softening the sensation of contact with the person caused by the inner portion 112.

Furthermore, when the reinforcing portion 400 is provided, the reinforcing portion 400 reinforces the area around at least one exhaust port 114 of the upper portion 111, thereby preventing the at least one exhaust port 114 from being crushed and partially or completely blocked due to the upper portion 111 being flexible.

Hereinafter, a wearable fan D according to a second embodiment of the present invention and several other embodiments including 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 portion 110' differs from the configuration of the bag portion 110 of the wearable fan D1. The differences will be described in detail below, and any explanation 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'.

In addition to the upper portion 111, inner portion 112, and outer portion 113, the bag portion 110' also has a bottom portion 117 (see Figures 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.

The tear strength of the upper portion 111, outer portion 113, and/or 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 outer portion 113, but is not limited to this.

The upper portion 111 is the portion located on the upper Z side of the bag portion 110'. The inner portion 112 is the 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.

The upper portion 111 can be formed in a generally mountain-like shape that convexes outward in the Y' direction (see Figure 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 ridge 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 downward in the Z' direction (see Figure 9). The inner end of the bottom portion 117 is shaped to conform to the lower end of the inner portion 112, and the outer end of the bottom portion 117 is shaped to conform to the lower end of the outer portion 113 (see Figure 10).

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

The mounting hole 115 is provided in the bottom 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 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'.

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

When using the wearable blower D2 described above, a mounting hole 115 is provided in the bag portion 110' so that it opens downward Z' and/or outward Y'. The fan 200 is fixed to the periphery of this mounting hole 115 and is exposed from the mounting hole 115. Therefore, when worn, the fan 200, which draws air into the bag portion 110', does not get in the way of a person.

Furthermore, when the wearable fan D2 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, allowing air to be blown 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 D2 can blow air between the front and/or back body and the person's body.

When the tear strength of the upper portion 111 is greater than that of the inner portion 112, the flexibility of the upper portion 111 prevents at least one exhaust port 114 in the upper portion 111 from being crushed and partially or completely blocked. When the tear strength of the bottom portion 117 is greater than that of the inner portion 112, the bottom portion 117 supports the fan 200 while softening the sensation of contact with the inner portion 112.

Furthermore, when the reinforcing portion 400 is provided, the reinforcing portion 400 reinforces the area around at least one exhaust port 114 of the upper portion 111, thereby preventing the upper portion 111 from being partially or completely blocked due to flexibility of the upper portion 111.

The wearable fan of the present invention is not limited to the above-described embodiment, and can be freely modified within the scope of the claims. This is described in more detail below.

The bag portion of the present invention can be constructed from rigid molded resin or the like. In this case, the bag portion can be constructed to have an upper portion 111, an inner portion 112, and an outer portion 113, or to have an upper portion 111, an inner portion 112, an outer portion 113, and a bottom portion 117. In the former case, the upper portion 111, the inner portion 112, and the outer portion 113 can be constructed as described above except that they are constructed from 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 can be constructed as described above except that they are constructed from molded resin or the like.

Although the bag portion of the present invention is described as having mounting holes, it may instead have at least one air intake port. In this case, the air intake port should open in a direction that includes at least one of the downward and outward directions, and the entire fan should be housed within the bag portion of the present invention and positioned so that it faces at least one air intake port.

At least one vent hole of the present invention may be located in the interior portion of the bag, rather than in the upper portion of the bag. In this case, the vent hole penetrates the interior portion and opens inward. Of course, the vent hole of the present invention may also be located in both the upper and interior portions of the bag. Furthermore, at least one vent hole of the present invention may be mesh-shaped.
