DETAILED DESCRIPTION OF THE INVENTION
[0009] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. [Electric fan configuration and usage examples] The configuration of an electric fan 1 according to an embodiment will be described with reference to Figures 1, 2A, and 2B. Figure 1 is a perspective view of the electric fan 1 according to the embodiment, as seen from the front. Figures 2A and 2B are exploded perspective views of the electric fan 1 according to the embodiment, as seen from the front and rear, respectively. In this application, the front and rear directions of the electric fan are defined as the air discharge side and the air intake side, respectively. As shown in FIGS. 1, 2A, and 2B, electric fan 1 includes case body 4 formed by assembling front case 2 and rear case 3, and fan 5 provided within case body 4.
[0010] The front case 2 has a cylindrical shape with a bottom, and an air outlet 6 is formed in the bottom 8. In this embodiment, the front case 2 has a cylindrical portion 7 and a dome-shaped bottom 8, and the air outlet 6 is formed in the bottom 8. A flange 9 is integrally formed on the end face of the cylindrical portion 7 on the opening side.
[0011] The rear case 3 has a cylindrical shape with a bottom, and an air intake port 10 is formed in the bottom portion 12. In this embodiment, the rear case 3 has a cylindrical portion 11 and a disk-shaped bottom portion 12, and the air intake port 10 is formed in the bottom portion 12. A flange 13 is integrally formed on the end surface of the cylindrical portion 11 on the bottom portion 12 side. The flange 13 constitutes a protruding portion as referred to in the present invention. In addition, a plurality of convex portions 14 that protrude radially are integrally formed along the circumferential direction of the flange 13.
[0012] 2A and 2B, the case main body 4 is constructed by aligning the opening of the front case 2 and the opening of the rear case 3, and assembling them so that the cylindrical portion 11 of the rear case 3 is detachably inserted inside the cylindrical portion 7 of the front case 2. For example, although not shown, a screw thread is formed on the outer peripheral surface of the cylindrical portion 11 of the rear case 3, and a groove is formed on the inner peripheral surface of the cylindrical portion 7 of the front case 2, so that the cylindrical portion 7 of the front case 2 and the cylindrical portion 11 of the rear case 3 are screwed together.
[0013] The fan 5 is a rotating body with multiple blades 5b provided around a shaft 5a, and is rotatably supported inside the front case 2. A motor (not shown) that serves as a drive source for rotating the fan 5 is built into the shaft 5a.
[0014] In this electric fan 1, the outer diameter R of the case body 4 is approximately 50 mm. By making the outer diameter R of the case body 4 60 mm or less, the electric fan 1 can be made small and can be attached to shirts and other items sold on the general market, improving convenience. It is also preferable that the front-to-back length (thickness) of the case body 4 be 30 mm or less. 1, 2A, and 2B are schematic diagrams for explaining the basic configuration of electric fan 1, and components not shown may be added. Since electric fan 1 needs to be connected to a battery that serves as its power source, terminal sections are provided in appropriate positions on case body 4 to connect to the terminals of a cord that connects to the battery.
[0015] FIG. 3 shows an example of a garment 200 to which the electric fan 1 is attached. FIG. 3 illustrates a long-sleeved shirt. An attachment hole 202 for attaching the electric fan 1 is formed in the flank area of the garment body 201. To attach the electric fan 1 to the attachment hole 202, the cylindrical portion 11 of the rear case 3 is inserted into the attachment hole 202 from the outside of the garment body 201, and the cylindrical portion 11 of the rear case 3 is assembled to the inside of the cylindrical portion 7 of the front case 2 inside the garment body 201. At this time, the electric fan 1 is fixed to the garment body 201 by sandwiching the area surrounding the attachment hole 202 between the end face on the opening side of the cylindrical portion 7 of the front case 2 and the flange 13 of the cylindrical portion 11 of the rear case 3. An interlining 203, which is harder than the fabric of the garment body 201, is provided in the area of the garment body 201 including the attachment hole 202, so that the electric fan 1 can be held without losing its shape.
[0016] Furthermore, by providing a flange 9 on the front case 2 and a flange 13 and a protrusion 14 on the rear case 3, it is possible to ensure a sufficient contact area with the surrounding area of the mounting hole 202. Furthermore, by providing the protrusion 14 on the rear case 3, it is possible to provide a handhold, making it easier to assemble the case main body 4. Furthermore, by making the bottom 12 of the rear case 3 flat, when the electric fan 1 is attached to the attachment hole 202, the electric fan 1 can be prevented from protruding from the garment body 201.
[0017] [Examples of clothing that can be fitted with electric fans] Next, a configuration in which the garment 200 includes the movable part 100 will be described with reference to Figures 4 and 5. Figure 4 is a schematic diagram showing the area of the garment 200 including the movable part 100, where (a) is a front view in the stored state and (b) is a side view in the pulled-out state. Figure 5 is a schematic diagram showing the area of the garment 200 including the movable part 100, where (a) is a perspective view in the stored state and (b) is a perspective view in the pulled-out state.
[0018] 3, when the attachment hole 202 is formed in the garment body 201, the electric fan 1 is positioned approximately perpendicular to the wearer's flank. In particular, in the case of a shirt or the like that is worn close to the wearer's body, the distance between the electric fan 1 and the body becomes short, and the air discharged from the air outlet 6 hits the body immediately after being discharged and is weakened, which tends to reduce the efficiency of air circulation within the garment body 201.
[0019] Therefore, the garment body 201 is provided with a movable part 100 whose angle with respect to the garment body 201 is variable. In the following, with reference to Fig. 3, a description will be given assuming that the movable part 100 is provided in the flank area of the garment body 201 (shirt) instead of the attachment hole 202. The movable part 100 is positioned so that the direction indicated by the arrow U in the figure is upward (towards the armpits of the wearer). The movable part 100 includes a flat part 101 and an elastic part 102 provided between the flat part 101 and the garment body 201 .
[0020] The flat portion 101 is a rectangular cloth part, and is connected to the garment body 201 by sewing a lower edge 101a of its periphery to the garment body 201. An opening 204 is formed in the side of the garment body 201 (see FIG. 5(b)), and the flat portion 101 can close the opening 204.
[0021] The stretchable section 102 is provided between the upper edge 101b and left and right edge sections 101c, 101d of the flat section 101 and the garment main body 201. The stretchable section 102 is composed of a substantially rectangular accordion-like stretchable cloth part 102a that spans between the upper edge 101b of the flat section 101 and the garment main body 201, and a substantially fan-shaped accordion-like stretchable cloth part 102b that spans between the left and right edge sections 101c, 101d of the flat section 101 and the garment main body 201.
[0022] The flat portion 101 is then formed with an attachment hole 103 into which the electric fan 1 is attached. The method of attaching the electric fan 1 to the attachment hole 103 is the same as the method of attaching the electric fan 1 to the attachment hole 202 described above, and therefore a description thereof will be omitted. The flat portion 101 is made of the same fabric as the garment body 201, and an interlining that is harder than the fabric of the garment body 201 is provided in the area including the attachment hole 103, so that the electric fan 1 can be held without losing its shape. Alternatively, the fabric of the flat portion 101 itself may be harder than the fabric of the garment body 201.
[0023] As shown in FIGS. 4(a) and 5(a), the movable part 100 configured as described above is put into a stored state in which the flat part 101 is flush with the garment main body 201 by contracting the stretchable part 102. Note that "flush" here means "approximately flush," including irregularities of the same order as the thickness of the flat part 101. Buttons 104 are provided on the flat part 101, and the stored state can be maintained by hooking the buttons 104 onto the garment main body 201. Note that the retention structure for maintaining the stored state is not limited to a structure using buttons 104, and may also use wire fasteners, hook-and-loop fasteners, etc.
[0024] As shown in Fig. 4(b) and Fig. 5(b), by stretching the stretchable part 102, the flat part 101 is inclined relative to the garment body 201 and assumes a drawn-out state. In the drawn-out state, the flat part 101 faces downward. Figs. 4 and 5 show a state in which the electric fan 1 is not attached, but if the electric fan 1 is attached, the drawn-out state (the flat part 101 faces downward) is maintained by its own weight. Note that a shape-retaining member made of synthetic resin or the like may be provided in an appropriate position on the movable part 100 to create a structure that can maintain the desired angle.
[0025] By providing the movable part 100 on the garment 200 in this way, the wearer can adjust the direction of the airflow by angling the electric fan 1 when it is pulled out. This prevents the air discharged from the air outlet 6 from hitting the body and being weakened immediately after being discharged, improving the efficiency of air circulation within the garment body 201. When the movable part 100 is positioned on the flank area of the garment body 201, the air can be directed directly to the wearer's armpits, ensuring coolness.
[0026] Modified examples of the movable part 100 will be described with reference to Figures 6 and 7. Figure 6 is a schematic diagram showing the area including the movable part 100 in the garment 200, where (a) is a front view in the stored state and (b) is a side view in the pulled-out state. Figure 7 is a schematic diagram showing the area including the movable part 100 in the garment 200, where (a) is a perspective view in the stored state and (b) is a perspective view in the pulled-out state. 4 and 5, the stretchable section 102 is made up of accordion-style stretchable cloth parts 102a and 102b. In contrast, in the modified example shown in Figures 6 and 7, the stretchable section 102 is made up of a substantially rectangular, planar cloth part 102c that spans the upper edge 101b of the flat section 101 and the garment body 201, and a substantially fan-shaped, planar cloth part 102d that spans the left and right edges 101c and 101d of the flat section 101 and the garment body 201. As shown in Figures 6(a) and 7(a), the stored state is achieved by folding the fabric parts 102c and 102d inward to contract the stretchable part 102. As shown in Figures 6(b) and 7(b), the pulled-out state is achieved by stretching the stretchable part 102 by pulling the fabric parts 102c and 102d.
[0027] In the embodiment, an example has been described in which the electric fan 1 is attached to the side of a long-sleeved shirt, but the type of clothing 200 and the position where the electric fan 1 is attached are not limited.
[0028] [Example of mounting fixture for electric fan] Next, referring to Figs. 8 to 10, an embodiment will be described in which a wearing device 300 for attachment to a human body includes a movable part 100. While Figs. 3 to 7 illustrate clothing 200 as an example of an object to which an electric fan embodying the present invention is attached, the present invention is not limited to this and includes the wearing device 300 for attachment to a human body. Fig. 8 shows an example of the wearing device 300 to which the electric fan 1 is attached, where (a) is a perspective view of the wearing device 300 and (b) is a diagram for explaining how to attach the electric fan to a human body. Fig. 9 is a schematic diagram showing the wearing device 300, where (a) is a front view in a retracted state and (b) is a side view in a pulled-out state. Fig. 10 is a schematic diagram showing the wearing device 300, where (a) is a rear view and (b) is a perspective view in a pulled-out state.
[0029] 9 and 10, wearing device 300 includes a cloth box-shaped wearing device main body 301. Wearing device main body 301 has a front surface 301a, a back surface 301b that faces the wearer, upper and lower surfaces 301c and 301d, and left and right surfaces 301e and 301f.
[0030] An opening 304 is formed in the front surface 301a, which is a predetermined surface of the wearing device main body 301, and a movable part 100 is provided thereon. The movable part 100 is connected to the wearing device main body 301 at a lower edge 101a of its periphery and comprises a flat part 101 that can close the opening 304, and an expandable part 102 that is provided between the wearing device main body 301 and an upper edge 101b and left and right edge parts 101c, 101d of the flat part 101. The movable part 100 has the same configuration as that described above, and a detailed description thereof will be omitted.
[0031] Furthermore, mesh material 302, which is a material that allows air to pass through, is provided on a part of rear surface 301b and upper surface 301c of wearing device main body 301. Although mesh material 302 is used, holes that allow air to pass through may be formed on rear surface 301b and upper surface 301c. Furthermore, cover parts may be provided to allow the amount of air passing through from rear surface 301b and upper surface 301c to be adjusted.
[0032] In addition, a belt insertion portion 303 is provided on the back surface 301b of the wearing tool main body 301, and as shown in FIG. 8, a belt 305 can be passed through it.
[0033] As shown in FIG. 8, the wearing device 300 constructed in this manner can be worn by wrapping the belt 305 through the belt insertion portion 303 around the body. For example, by wrapping the belt 305 around the waist and wearing an outer garment (other than EF wear), it is possible to achieve the same function as wearing EF wear. For example, as shown in FIG. 8(b), a shirt SH can be worn with the bottom of the shirt exposed to cover the wearing device 300. Alternatively, the wearing device 300 can be worn over the shirt to wear an outer garment. Note that one or more wearing devices 300 may be attached to the belt 305. Furthermore, the position of the wearing device 300 can be freely set by changing the position of the wearing device 300 relative to the belt 305.
[0034] By providing the movable part 100 to the wearing device 300 in this way, in the stored state, air discharged from the air outlet 6 of the electric fan 1 passes through the wearing device main body 301 and is discharged mainly from the back surface 301b (arrow A1 in Figure 8). In this way, the electric fan 1 can be separated from the wearer's body by the thickness of the box-shaped wearing device main body 301, preventing the air discharged from the air outlet 6 from hitting the body and being weakened immediately after being discharged, and improving the efficiency of air circulation within the garment main body.
[0035] In the extended state, air discharged from the air outlet 6 of the electric fan 1 passes through the wearing device main body 301 and is discharged mainly from the top surface 301c (arrow A2 in Figure 8). In this way, the wearer can adjust the direction of the air by angling the electric fan 1. This prevents the air discharged from the air outlet 6 from being weakened by hitting the body immediately after being discharged, improving the efficiency of air circulation within the garment main body.
[0036] Although the air is allowed to pass through the back surface 301b and the top surface 301c of the wearing device main body 301, this is not limitative. For example, when wearing the wearing device 300 inside underwear such as pants or a skirt, the air may be allowed to pass through the back surface 301b and the bottom surface 301d of the wearing device main body 301.
[0037] As described above, the convenience can be improved in a configuration in which the electric fan 1 is attached to an object to be worn (clothing 200 or wearing tool 300).
[0038] Although the present invention has been described above with reference to the embodiments, the above-described embodiments are merely examples of specific embodiments for carrying out the present invention, and the technical scope of the present invention should not be interpreted as being limited by these embodiments. In other words, the present invention can be carried out in various forms without departing from its technical concept or main features. In the embodiment, the planar portion 101 of the movable portion 100 is rectangular, but may be circular or the like. [Explanation of symbols]
