Description

The present invention relates to a fan device, fan-equipped clothing, and a fan body mounting fixture.

In recent years, fan-equipped clothing has come into practical use. The fan unit is attached to a flat fan mounting hole in the garment body, and the large amount of outside air taken in by the fan unit is circulated roughly parallel to the surface of the body or underwear, evaporating sweat from the body and cooling the body.

In such fan-equipped clothing, the fan unit can be attached and detached from the clothing body, for example, to clean the clothing or to replace the fan unit. A known method for attaching the fan unit's fan body to the clothing body via an attachment ring is a screw-type method (see Patent Document 1) in which male and female threads are provided on the outer wall of the fan body and the inner wall of the attachment ring, respectively, and screwed together. Another known method is a one-touch type (see Patent Document 2) in which an elastic elliptical attachment ring is pressed so as to deform the ring into a perfect circle, and then fitted onto the perfect circular fan body, and the force pressing the attachment ring is released to fix the ring in place by the restoring force.

JP 2020-139422 A JP 2019-137964 A

However, in the case of the screw type as described above, although the mounting ring is difficult to remove, it can be time-consuming to attach and remove. Also, in the case of the one-touch type, the fan body can be easily attached and removed, but when the wear body is pulled with a strong force, a force opposite to the restoring force acts on the mounting ring, which can cause it to come off.

The object of the present invention is to provide a fan device, fan-equipped clothing, and fan body attachment tool that are easy to attach and detach and in which the fan body does not easily come off the clothing body.

The following describes in detail the embodiments of the fan-equipped wear according to the present invention with reference to the drawings. However, the embodiments described below are subject to various limitations that are technically preferable for implementing the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples.

First, the overall configuration of the fan-equipped wear 100 will be described with reference to FIG.
In the following description, the fan-equipped garment 100 will be described based on the state in which it is worn by a wearer, with the front side of the wearer defined as front, the back side of the wearer defined as back, the upper side of the wearer defined as top, the lower side of the wearer defined as bottom, the right hand side of the wearer defined as right, and the left hand side of the wearer defined as left.

[Fan-equipped clothing]
The fan-equipped wear 100 comprises, for example, a wear body 210, a fan unit 1 that introduces air into the wear body 210, a power supply unit 230 that supplies power to the fan unit 1, and a connection cable 240 that connects the power supply unit 230 and the fan unit 1. The air taken into the wear body 210 by the fan unit 1 is circulated along the surface of the wearer's body or underwear, thereby evaporating sweat from the body and cooling the body with the heat of vaporization generated during evaporation.

[Clothing]
The garment body 210 is formed into a shape covering the torso and arms of the wearer, using a sheet-like member 200 that is either non-breathable or has a degree of breathability that allows it to be inflated by the introduction of air by the fan device 1. As shown in Fig. 1, the garment includes, for example, a pair of opening/closing means 211, 212, air leakage prevention means 213, an attachment hole 214, an air exhaust section 215, a power supply unit holding means 216, and a cable holding means 217.

(Opening and closing means, air leakage prevention means)
The pair of opening/closing means 211, 212 are detachable divided parts formed on the front part of the garment body 210 with linear fasteners or the like, and allow the front part of the garment body 210 to be opened and closed.
The air leakage prevention means 213 is formed by providing an elastic member such as an elastic band around the wearer's body at the bottom of the garment body 210. This prevents air in the space between the garment body 210 and the wearer's body from leaking out from the bottom of the garment body 210 to the outside.

(Mounting hole)
The attachment holes 214 are circular holes provided on the rear body of the garment body 210 at positions corresponding to the left and right sides of the wearer's waist, and have openings 201 formed in the sheet-like member 200.
The opening 201 is a hole that connects the outside with the space between the garment body 210 and the wearer's body when the fan-equipped garment 100 is worn, and the fan device 1 is attached to the opening 201 .

The positions at which the attachment holes 214 are formed are not limited to the positions described above. Specifically, the attachment holes 214 may be formed on the side or front surface of the garment body 210, for example.
Furthermore, the number of mounting holes 214 in one garment body 210 is not limited to two. A number of mounting holes 214 less than or greater than two may be formed, and a corresponding number of fan devices 1 may be attached thereto.
In addition, it is preferable that the periphery (edge) of the attachment hole 214 is reinforced. Specifically, for example, a flat ring-shaped member made of plastic or the like may be attached, or the portion of the sheet-like member 200 forming the garment body 210 around the attachment hole 214 may be folded back and sewn.

(Air exhaust section)
The air exhaust section 215 is an opening for exhausting the air introduced into the space between the wearer's body 210 and the wearer's body by the fan device 1 after circulating it along the wearer's body or underwear. Specifically, for example, the air exhaust section 215 is formed in an opening between the wearer's neck and the end of the collar of the wearer's body 210 and an opening between the wearer's arm and the end of the sleeve of the wearer's body 210.

(Power supply unit holding means, cable holding means)
The power supply unit holder 216 is a pocket-shaped holder formed on the inner surface of the garment body 210 to hold the power supply unit 230 in a position where it can supply power to the fan device 1 .
The cable holding means 217 is a ring-shaped holding means formed with an opening through which the connection cable 240 can be inserted, in order to hold the connection cable 240 on the inner surface side of the garment body 210 .

[Fan device]
As shown in FIG. 1, the fan unit 1 is attached to the garment body 210 by inserting it through the mounting hole 214, and is a device for introducing air through the mounting hole 214 into a specified space between the garment body 210 and the wearer's body, and the necessary power is supplied from the power supply unit 230 via a connection cable 240.

As shown in FIG. 2B , the fan unit 1 includes a fan body 10 that realizes the air blowing function of the fan unit 1, and a fan body attachment tool (fan attachment means) 30, which is a dedicated tool for attaching the fan body 10 to the garment body 210.
Specifically, the fan device 1 comprises a fan body 10 having a cylindrical portion 21, and a flange portion 22 that protrudes from one axial end of the cylindrical portion 21 in a direction approximately perpendicular to the axial direction of the cylindrical portion 21 and has an outer shape that is sufficiently larger than the outer shape of the mounting hole 214, and a fan body mounting fixture 30 that is attached to the fan body 10 with a sheet-like member 200 sandwiched between the flange portion 22 and the fan body mounting fixture 30 so as to cover the entire circumference of the cylindrical portion 21 from the outer periphery, thereby fixing the fan body 10 to the wear body 210.

(Fan body)
2A and 3, the fan body 10 is made up of a main body case 11, a motor (not shown) built into the main body case 11, a propeller (blades) 12 attached to the rotating shaft of the motor, and a connector (not shown) for supplying power to the motor. Although a detailed explanation is omitted, the main body case 11 is made up of two parts, an upper part and a lower part, and is formed by combining and joining these parts.
As shown in FIG. 3 , the main body case 11 includes, from the top, a first flow section 13 , a flanged tubular section 20 , and a second flow section 14 .

<First Distribution Department>
As shown in Figure 3, the first flow section 13 is composed of a central base 131 that is approximately circular when viewed from above, a plurality of first rod-shaped sections 132 extending radially from the central base 131, and a first ring-shaped section 133 centered on the central base 131.
The portion consisting of the plurality of first rod-shaped portions 132 and the first ring-shaped portions 133 has sufficient breathability, so that outside air can be taken in when the propeller 12 rotates. This portion also prevents fingers and the like from entering from the outside, and can protect fingers from the rotating propeller 12.

<Cylindrical part with flange>
As shown in FIG. 3 , the flanged tubular portion 20 is made up of a flange portion 22 formed to be continuous with the first rod-shaped portion 132 of the first flow portion 13 , and a hollow tubular portion 21 .
The cross section of the cylindrical portion 21 taken along a plane perpendicular to the central axis thereof is substantially circular. A plurality of grooves 23, which are holes, are provided on the outer surface at locations corresponding to the claws 34 described below, and a plurality of protrusions 24 are provided on locations corresponding to the cutouts 31c described below.

<Second Distribution Department>
As shown in Figure 3, the second flow section 14 consists of a plurality of second rod-shaped sections 142 and second ring-shaped sections 143, a motor fixing section 144 for fixing the motor, and a motor cover 145 attached to the underside of the motor fixing section 144.
Like the first flow section 13, the section consisting of the plurality of second rod-shaped sections 142 and the second ring-shaped sections 143 has sufficient breathability. This section also prevents fingers from entering from the outside, thereby protecting fingers from the rotating propeller 12.

Since the main body case 11 is configured in this manner, when the motor fixed to the motor fixing part 144 rotates and the propeller 12 rotates, the outside air taken in from the first circulation part 13 can be discharged from the second circulation part 14, and the outside air can be circulated in the space between the garment main body 210 and the wearer's body.

[Fan body mounting bracket]
As shown in FIGS. 4A and 4B, the fan body attachment fixture 30 includes a ring member 31, a fixing member 32, a fitting portion 33, a claw portion 34, and a ring flange portion 35.
The fan body mounting fixture 30 is preferably strong and lightweight, and is preferably made of, for example, ABS resin, but is not limited to this.

(Ring member)
The ring member 31 is composed of two divided bodies 31a, 31a. A fixing member 32 is provided at the longitudinal ends of the two divided bodies 31a, 31a, and the ends of the two divided bodies 31a, 31a are fixed to each other.

In the closed state, the ring member 31 is a generally circular member when viewed from above, having an inner surface 31b that is generally the same as or slightly larger than the shape of the outer surface of the cylindrical portion 21, and a notch 31c is provided in the inner surface 31b.
By providing the ring member 31 with the cutout portion 31c corresponding to the protrusion 24, the protrusion 24 is guided into the cutout portion 31c when the ring member 31 is attached to the fan body 10, and the ring member 31 can be more easily attached to the fan body 10. Furthermore, the engagement between the protrusion 24 and the cutout portion 31c makes it more difficult for the ring member 31 to rotate.

(Fixing member)
The fixing member 32 is provided at the ends of the two divided bodies 31a, 31a to fix the two divided bodies 31a, 31a together, and includes a first fixing member 32a and a second fixing member 32b.

<First fixing member>
The first fixing member 32a fixes the ends of the two divided bodies 31a, 31a to each other so that they can rotate around the first fixing member 32a as an axis. This allows the ring member 31 to be freely closed (see FIG. 4A) or open (see FIG. 4B). The first fixing member 32a only needs to be able to open the ring member 31 as much as possible to accommodate the fan body 10, and may be any suitable known structure such as a flag hinge.

<Second fixing member>
The second fixing member 32b is a detachable member that can fix the ring member 31 in the closed state by engaging with each other as shown in Fig. 4A. Specifically, as shown in Fig. 4B, the second fixing member 32b is a rotatable hook 32ba and a fastener 32bb, and the closed state can be achieved by rotating the hook 32ba toward the fastener 32bb to be in an engaged state, and the open state can be achieved by rotating the hook 32ba away from the fastener 32bb to release the engaged state.
The second fixing member 32b is not limited to the hook 32ba and the fastener 32bb, and any other suitable known configuration may be used.

(Fitting part)
The mating portion 33 is a pair of recessed portions 33a and protruding portions 33b provided at the ends of the two divided bodies 31a, 31a, respectively, and is configured so as to be mated with each other by inserting the protruding portion 33b into the recessed portion 33a, as shown in Figure 4A.

In the present invention, the second fixing member 32b increases the strength of the ring member 31 against external forces in the opening direction, and the fitting portion 33 increases the strength of the ring member 31 against external forces in the twisting direction. In addition, by providing the fitting portion 33, it is possible to prevent the ring member 31 from becoming misaligned when it is put into the closed state.

(claw part)
The claw portion 34 is a protrusion provided on the inner surface of the ring member 31, and is formed to fit into the groove portion 23 of the cylindrical portion 21. By providing the groove portion 23 and the claw portion 34 that fit into each other, and fitting the claw portion 34 into the groove portion 23 when attaching the fan body mounting fixture 30 to the fan body 10, it is possible to prevent the ring member 31 from rotating relative to the fan body 10.
It is preferable that the circumferential width of the claw portion 34 is approximately the same as the circumferential hole width of the groove portion 23 .

(Ring flange part)
The ring flange portion 35 is a member that protrudes from the lower end of the side surface of the fan body attachment fixture 30 in a direction approximately perpendicular to the side surface, and has an outer shape that is sufficiently larger than the outer shape of the attachment hole 214.
Since the fan body mounting fixture 30 is provided with the ring flange portion 35, when the fan body 10 is attached to the wear body 210, the ring flange portion 35 is positioned opposite the flange portion 22, thereby further increasing the fixing strength of the fan device 1.

[How to install the fan]
In order to attach the fan body 10 to the garment body 210 using the fan body attachment tool 30 as described above, the following steps (1) to (3) may be followed.
(1) The fan body 10 is inserted into the opening 201 of the mounting hole 214 from the outside of the wear body 210, and the sheet-like member 200 and the flange portion 22 are brought into contact with each other.
(2) Next, from the inside of the garment body 210, the ring member 31 is attached by changing from an open state to a closed state so as to cover the entire circumference of the tubular portion 21 from the outer periphery so that the ring flange portion 35 contacts the sheet-like member 200 and the claw portion 34 fits into the groove portion 23.
(3) Next, after the fitting portion 33 is fitted, the ring member 31 is fixed in the closed state by the second fixing member 32b.

[Effects of the Invention]
In the fan unit 1 according to this embodiment, the fan unit 1 is fixed to the garment body 210 by attaching the fan body attachment tool 30 to the fan body 10 as described above. That is, as shown in Fig. 5, the sheet-like member 200 around the opening 201 is sandwiched between the rear surface of the flange portion 22 and the ring member 31, so that the fan unit 1 can be reliably attached to the garment body 210. Also, the fan unit 1 can be attached and fixed to the garment body 210 more easily than in the case of attaching the fan unit by means of screws.

In addition, in the case of a one-touch type in which the fan is fixed by fitting an elastic elliptical ring member onto the outside, the ring member needs to be thin so that it can be easily deformed by pressure, but the present invention does not have such a restriction. Therefore, the thickness of the ring member 31 can be made arbitrary depending on the purpose.

In the case of one-touch type, it was difficult to provide a flange for pressure deformation, but the present invention does not have such a limitation. And by providing the fan body mounting fixture 30 with a ring flange portion 35 that is larger than the outer shape of the mounting hole 214, the risk of the fan unit 1 coming off can be further reduced.

[Modification]
Note that Figures 2A to 4B illustrate a ring member 31 that is approximately circular when viewed from above and is attached to a fan body 10 that is approximately circular when viewed from above, but the shapes of the fan body 10 and the ring member 31 are not limited to this and may be, for example, polygonal.

In addition, in Figure 3, the fan body 10 is illustrated in which groove portions 23 whose axial width is approximately the same as the sum of the front-to-rear width of the sheet-like member 200 (i.e., the thickness of the sheet-like member 200) and the axial width of the claw portions 34 are provided in the cylindrical portion 21 in a number corresponding to the number of claw portions 34 provided on one ring member 31 (two in Figure 3), but this is not limited to this.
6, multiple grooves 23 having different axial hole widths may be provided, which alleviates restrictions on the thickness of the garment body 210 to be worn. In other words, the garment body 210 to which the fan device 1 can be worn can be significantly expanded from thin to thick.
In this case, it is more preferable to make it easier to determine which groove 23 the claw portion 34 should be fitted into in the garment body 210 currently being used by, for example, printing a different symbol in the vicinity of each groove 23 having a different axial hole width, or coloring the vicinity of each groove 23 having a different axial hole width in a different color, as shown in Figure 6.

Further, although FIGS. 3 and 4A show the case where the groove portion 23 and the claw portion 34 are provided at approximately the center in the axial direction of the cylindrical portion 21 and the fan body mounting fixture 30, the present invention is not limited to this.
As described above, when the fan body 10 has multiple groove portions 23 with different axial hole widths, by providing the groove portions 23 and the claw portions 34 at the axial ends, etc., the fan body mounting fixture 30 can be used upside down to adjust the way in which the sheet-like member 200 and the claw portions 34 engage in the groove portions 23 according to the thickness of the sheet-like member 200.
In this case, the ring flange portion 35 may be provided not only at the lower end portion of the ring member 31 but also at the upper end portion so that approximately the same fixing strength can be ensured regardless of whether the fan body mounting fixture 30 is used on the top or bottom.

In addition, in FIG. 4B and other figures, a case is illustrated in which a first fixing member 32a and a second fixing member 32b are provided at both ends of one divided body 31a, but this is not limited thereto. As shown in FIG. 8, a second fixing member 32b may be provided at both ends of one divided body 31a, so that the divided bodies 31a, 31a can be separated.

Furthermore, while FIG. 3 illustrates a fan body 10 with two grooves 23, and FIG. 4A and FIG. 4B illustrate a ring member 31 with two claws 34, this is not limited thereto, and the fan body 10 may have fewer or more than two grooves 23 and claws 34.

Depending on the fixing strength of the fan unit 1, the ring member 31 may not have a ring flange portion 35, as shown in FIG. 7.

In this example, the shape of the tubular portion 21 has been described as being cylindrical, but it may be other shapes such as a rectangular prism, and the ring member 31 may be formed according to the shape of the tubular portion 21. Furthermore, in this example, the ring member 31 has been described as being composed of two members, but it can be modified as appropriate, for example, to be composed of three parts. Of course, other specific details of the structure can also be modified as appropriate.
