Description

The present application relates to a clothes fan, a non-slip plate member, and a rain cover for a clothes fan that are attached to clothes to obtain a feeling of coolness when working outdoors in the sunlight.

I feel a great deal of pain when I go out on a hot summer day. Especially when working outdoors in the sunlight, it is even more difficult. In the past, work clothes equipped with a fan to withstand extreme heat have been popular. However, due to the abnormally high heat in recent years, it has become necessary for ordinary people other than workers to attach a fan to their clothes.

However, conventional work clothes with a fan attached are expensive, and it is hard to say that many people can obtain them. For this reason, ordinary people have begun to attach holes to clothes by making holes having the same shape as the fans, and in recent years, fans having small size, light weight, and high output have been developed. However, if the fan is not firmly attached to the hole formed in the clothes, the fan may fall off due to hitting the clothes or pulling the clothes. Therefore, it is necessary to reinforce the periphery of the hole formed in the clothes, but this work is very time-consuming and costly. As the clothes fan of this type, for example, the techniques described in Patent Documents 1 to 3 are disclosed.

And a fan cover portion 30 which is attached to the fan main body 10 and covers the fan main body 10. Further, an annular plate-shaped non-slip plate member 40 provided with a large number of anti-slip projections 43 is interposed between the fan cover portion 30 and the cloth 61. Hereinafter, each component will be described in detail.

The fan main body 10 is attached to the mounting hole 61a formed in the cloth 61 of the garment 60, and various types can be obtained on the market. The fan body 10 has a circular plan shape, includes a motor, and has a connector 11 attached thereto via a lead wire 12. The battery, which is usually the power source of the fan body 10, is fixed to a pants band or the like. The connector 13 on the battery side is connected to the connector 11 of the fan main body 10, and the blades of the fan main body 10 are rotated by an on/off switch of the battery storage box to guide the outside air into the clothes 60 for cooling.

The motor drive power of the fan main body 10 is usually 5 to 12 volts and 0.15 to 0.30 amperes. Fans in this range can be used for 4-8 hours with a single charge of the battery. Moreover, even if it is outside of these ranges, a high power motor or a low power motor can be used depending on the application.

The fan body accommodating portion 20 is made of synthetic resin, and has a cylindrical cylindrical body 21 in which the fan body 10 is accommodated, a flange 22 that horizontally protrudes outward from one side opening of the cylindrical body 21, and a cylinder. The air suction part 23 provided in the other side opening of the body 21. The cylindrical body 21 has a size and a planar shape capable of accommodating the fan main body 10, and a screwing portion 24 made of a male screw is formed on the outer peripheral surface thereof. The flange 22 is formed in an annular plate shape, and the fan main body 10 is inserted therethrough.

On the surface of the flange 22 facing the front side surface 62 of the fabric 61, a large number of anti-slip projections 25 are provided at predetermined intervals over the entire surface. Here, the front side surface 62 of the cloth 61 refers to a surface facing the outside of the garment 60. The anti-slip protrusion 25 is formed in a conical shape having a predetermined height. However, the non-slip protrusions 25 may have other shapes such as a quadrangular pyramid and a triangular pyramid. In short, the fabric 61 is strongly pressed or bites into the fabric 61 so that the flange 22 is in the surface direction with respect to the fabric 61. Any shape may be used as long as it can prevent movement. The air suction portion 23 is formed by a large number of ribs 26 arranged radially, and the outside air passes between the ribs 26 and is taken into the fan body housing portion 20. The ribs 26 reinforce the entire structure of the fan body housing portion 20 and prevent foreign matter from being sucked into the fan body 10 to impede the rotation of the blades and damage the drive motor.

Specifically, as shown in FIG. 4( b ), the non-slip projections 25 of the flange 22 of the fan body housing portion 20 are provided in large numbers on the two large and small circles having slightly different diameters at predetermined intervals in the circumferential direction. ing. However, the anti-slip projections 25 are not limited to this arrangement.

The fan cover portion 30 has a cylindrical tubular body 31, an air blowing portion 32 provided in one opening of the tubular body 31, and a flange 33 that laterally projects from the other opening of the tubular body 31. .. The cylindrical body 31 has a threaded portion 34, which is a female screw, to which the threaded portion 24 of the fan main body storage portion 20 is screwed, and is formed on the inner peripheral surface. A large number of ribs 35 are formed in the air blowing portion 32, and the air generated in the fan body 10 is blown into the clothes 60 through the gaps between the ribs 35 of the air blowing portion 32. At the center of the air blowing portion 32, an insertion hole 36 through which the lead wire 12 from the motor of the fan body 10 is inserted is provided.

The non-slip plate member 40 is made of a synthetic resin and has an annular plate-like member having a plate thickness of, for example, about 1.5 to 2 mm, and holds the cloth 61 with the flange 22 of the fan body housing section 20. is there. The non-slip plate member 40 is provided with a large number of anti-slip projections 43 at predetermined intervals on the surface facing the back side surface 63 of the cloth 61. Here, the back side surface 63 of the cloth 61 refers to the surface facing the inside of the garment 60. It is preferable that the non-slip plate member 40 has the same shape and the same size as the flange 22 of the fan main body housing section 20. The non-slip plate member 40 is provided with an uneven finger hook 45 on its outer peripheral edge portion for easy handling.

Specifically, as shown in FIG. 4( a ), the non-slip protrusions 43 are arranged on two circles having the same diameter as the circle on which the non-slip protrusions 25 of the flange 22 of the fan body housing 20 are arranged. Many are provided at predetermined intervals in the direction. However, the anti-slip projections 43 are provided in a phase out of alignment with the anti-slip projections 25 of the flange 22 of the fan main body housing section 20. That is, the anti-slip projections 43 are provided between the many anti-slip projections 25 provided on the flange 22 of the fan main body housing portion 20, and do not overlap or interfere with the anti-slip projections 25. Thus, when the flange 22 of the fan main body housing 20 and the anti-slip plate material 40 sandwich the cloth 61, the anti-slip projections 25 and 43 press the cloth 61 so as to mesh with each other, as shown in FIG. Or cut into this.

The anti-slip protrusions 43 of the anti-slip plate member 40 are formed in a conical shape having a predetermined height, like the anti-slip protrusions 25 of the flange 22 of the fan body housing section 20. However, the non-slip protrusions 43 may have other shapes such as a quadrangular pyramid and a triangular pyramid, and in short, the cloth 61 is pressed or bites into the cloth 61 so that the non-slip plate member 40 is in the surface direction with respect to the cloth 61. Any shape may be used as long as it can prevent movement.

Next, a method of attaching the clothes fan 1 of the present embodiment configured as above to the clothes 60 will be described.
First, the cloth 61 of the garment 60 is cut into a circle at a position where the garment fan 1 is to be mounted to form a mounting hole 61a having a size corresponding to the outer diameter of the fan body 10. Next, the fan body 10 is housed inside the tubular body 21 of the fan body housing portion 20. Then, the cylinder body 21 of the fan main body 10 and the fan main body accommodating portion 20 are integrally inserted into the mounting hole 61 a of the cloth 61, and the flange 22 of the fan main body accommodating portion 20 is applied to the front side surface 62 of the cloth 61. In this state, the tubular body 21 of the fan body housing portion 20 projects to the back side of the cloth 61, and the anti-slip projections 25 of the flange 22 contact the front side surface 62 of the cloth 61.

Next, from the opposite side of the cloth 61, that is, the back surface side, with the anti-slip projections 43 facing the cloth 61, the tubular body 21 of the fan main body accommodating part 20 is inserted while being inserted into the central hole 40a of the anti-slip plate 40. The non-slip plate material 40 is applied to the back side surface 63 of the fabric 61. Next, while rotating the fan cover portion 30 by hand, the tubular body 31 of the fan body housing portion 20 is covered with the tubular body 31 of the fan body housing portion 20 while the threaded portion 34 formed of a female screw is attached to the male body of the tubular body 21 of the fan body housing portion 20. It is screwed onto the screwing portion 24 made of a screw. As a result, the clothes fan 1 is attached to the clothes 60. In this state, the cloth 61 is sandwiched between the flange 22 of the fan main body storage section 20 and the non-slip plate material 40, and the two anti-slip projections 25 and 43 press the cloth 61 or the tip of the cloth sticks into the cloth 61, thereby The fan 1 is firmly attached to the clothes 60.

Next, the operation of the clothes fan 1 of this embodiment will be described.
The clothes fan 1 includes a non-slip plate member 40. The flange 22 of the fan main body storage unit 20 and the non-slip plate member 40 sandwich the cloth 61 from both front and back sides of the garment 60, and the flange 22 of the fan main body storage unit 20. Since the non-slip plate members 40 are provided with the anti-slip protrusions 25 and 43, the anti-slip protrusions 25 and 43 strongly press the fabric 61 or cut into it. For this reason, the flange 22 of the fan body accommodating portion 20 and the non-slip plate member 40 firmly hold the cloth 61, and the slipping on the cloth 61 is prevented. This reliably prevents the clothes fan 1 from falling off the clothes 60 during use. As a result, even in the ready-made garment 60, the fan can be firmly fixed to the garment 60 by providing the circular mounting hole 61a in the garment 60 and mounting the anti-slip plate member 40, and with a simple structure. The fan can be fixed easily and inexpensively. When the circular attachment hole 61a is provided in the garment 60, it is not necessary to reinforce the periphery thereof.

By the way, the flange 22 and the anti-slip plate member 40 of the fan main body housing portion 20 are provided with anti-slip projections 25 and 43 on the surface facing the cloth 61, respectively. As shown in the drawings, the flange 22 of the fan main body housing 20 has a ring-shaped fitting concave-convex portion 27 centered on the shaft core 22a of the flange 22 on the surface facing the fabric 61, and slips. On the surface of the stopper plate member 40 facing the fabric 61, a fitting concave-convex portion 46 having a U-shaped cross section is formed in an annular shape around the axis 40b of the anti-slip plate member 40, and the fitting concave-convex portion 27 of the flange 22 is formed. It is also possible to provide the non-slip plate member 40 and the fitting concavo-convex portion 46 that fit with each other. In this case, as shown in FIG. 6(c), the flange 22 of the fan main body housing portion 20 and the non-slip plate member 40 are covered with the cloth 61 while the fitting uneven portion 27 and the fitting uneven portion 45 are fitted to each other. Since it is sandwiched, like the one shown in FIG. 4, it is possible to reliably prevent the flange 22 and the non-slip plate member 40 of the fan main body housing portion 20 from sliding on the cloth 61 along the surface.

<Second Embodiment>
Next, a clothes fan according to a second embodiment of the present invention will be described with reference to FIG.
In the clothes fan 1 of the first embodiment, the non-slip projections 25 are provided on the flange 22 of the fan body housing portion 20, but in the clothes fan 1 of the second embodiment, the anti-slip projections are provided separately. Only the point provided on the first anti-slip plate member 41 differs from the clothes fan 1 of the first embodiment.

In FIG. 7, the flange 22 of the fan body accommodating portion 20 is formed in a flat surface without any anti-slip protrusion. The anti-slip projections on the fan main body storage section 20 side are provided on the surface of the first anti-slip plate member 41, which is a separate body, on the side facing the cloth 61. The same anti-slip plate material 40 as that of the first embodiment is provided as the second anti-slip plate material 42 on the fan cover 30 side. That is, the clothes fan 1 according to the second embodiment is provided with the two first anti-slip plate members 41 and the second anti-slip plate members 42 as separate members.

Therefore, the first anti-slip plate member 41 provided with the anti-slip projections 44 is provided for the existing clothes fan in which the anti-slip projections are not provided on the fan main body storage section 20 side or the fan cover section 30 side. If the clothes fan 1 is attached to the garment 60 by using two plate members, that is, the second anti-slip plate member 42 provided with the anti-slip protrusions 43, the cloth 61 is provided with these two members, as in the first embodiment. The non-slip plate material firmly clamps the clothes fan 1 and reliably prevents the clothes fan 1 from falling off the clothes 60 during use.

<Third Embodiment>
Next, a clothes fan according to a third embodiment of the present invention will be described with reference to FIG.
A rain shield cover 50 is provided in the fan body storage section 20. As shown in FIG. 8, the rain cover 50 has a cover portion 51 that protrudes outside the fan body housing portion 20 to prevent rainwater from entering the fan body housing portion 20, and air from the outside to the fan body. An air intake portion 52 having an opening for taking in the storage portion 20. Further, the rain cover 50 has a flange mounting groove 53 formed of a concave portion along the outer periphery of the bottom portion, and the outer peripheral edge portion of the flange 22 of the fan body accommodating portion 20 is inserted and held therein. As a result, the rain cover 50 is attached to the flange 22 of the fan body housing section 20. The rain cover 50 may be attached integrally with the flange 22 of the fan main body storage section 20.

In the clothes fan 1 according to the present embodiment, the cover portion 51 has a bellows structure, and the cover portion 51 overhangs the upper half portion of the fan body housing portion 20 to cover the entire upper half portion of the fan body housing portion 20, Cut off the rainwater pouring from. Since the cover portion 51 has a bellows structure, the rain cover 50 can be made compact while being able to fold the cover portion 51 to prevent it from hitting a person or an object when the weather is other than rainy weather or snow. The appearance will be improved. However, the cover portion 51 does not necessarily have to have a bellows structure.

The rain cover 50 is made of a rubber material such as silicon rubber, various elastic materials such as soft resin and elastomer, and soft materials. Since the rain shield cover 50 projects outside the clothes 60, it is for avoiding a risk of being injured by a person hitting the clothes and preventing the rain shield cover 50 itself from being damaged. Further, since a material such as silicone rubber has adhesiveness, it has an advantage that it is difficult to slip on the surface of the fabric 61. However, the rain cover 50 may be formed of a synthetic resin or the like that maintains a constant shape.

By the way, although the anti-slip plate member and the flange 22 of the fan main body accommodating portion 20 of each of the above-described embodiments are formed in an annular plate shape, the present invention is not limited to this, and the hexagonal shape is not limited thereto. It may be formed in a square shape such as an octagon or an annular shape such as an ellipse.
