Description

The present invention relates to a portable blower that reduces heat by blowing air into the upper garment worn by the user.

Conventionally, a wearing means for attaching to a waist belt wrapped around the waist of a user's trousers is provided, and an air discharge port sent from a blower mechanism is covered with clothes (top), and air is sent into the top. Therefore, there is known a blower device that softens the heat by utilizing the heat of vaporization when sweat evaporates (see Patent Document 1).

However, in the blower device described in Patent Document 1, when the blower device is attached to a belt and the discharge port is covered with a top, the user is in a forward bending posture with the upper body tilted down. There was a risk that the hem of the upper garment would roll up and the discharge port would be exposed to the outside of the garment, and each time the discharge port had to be returned to the inside of the upper garment.

In order to solve such a problem, Patent Document 2 has a configuration in which a mounting portion mounted on the waist belt and a main body portion connected to the mounting portion via a hinge portion are provided, and the upper body is provided. The main body swings around the hinge as a fulcrum according to the movement, so that the discharge port of the blower attached to the belt is not easily exposed to the outside of the clothes even when the user is in a forward bending posture. Blowers have been proposed.

However, when the blower is attached to the waist belt, when the user crouches or bends forward, the position of the blower and the upper garment is not a little misaligned, so the discharge port is external. It was difficult to completely prevent exposure to the belt, and there was room for improvement.

Therefore, an object of the present invention is to provide a blower device in which the position of the blower device and the upper garment is unlikely to shift even if the posture of the user changes.

The present invention has been made to solve the above problems, and the blower device of the present invention has a main body portion having a discharge port and an intake port and having a blower mechanism inside.
It has a mounting portion provided on the main body portion and held on the upper body above the position of the waist belt of the user.
The discharge port of the main body is arranged inside the upper garment, and the intake port is arranged so as to be exposed below the upper garment .
The main body portion is provided with a holding portion that is rotatably configured via a hinge portion and is configured so that the hem of the user's upper garment can be sandwiched between the main body portion and the outer peripheral surface of the main body portion.
An upper frame in which the holding portion extends in a substantially arc shape extending along the outer peripheral surface of the main body portion at a position separated from the hinge portion, and left and right vertical frames extending in the axial direction from both ends of the upper frame. It is characterized by having a lower frame extending from the lower end of each of the vertical frames to the hinge portion .

In the blower device of the present invention, it is preferable that the intake port is opened in a direction inclined with respect to the axial direction of the main body portion.

According to the present invention, it is possible to provide a blower device in which the position of the blower device and the upper garment is less likely to shift even if the posture of the user changes.

It is a perspective view of the blower which is one Embodiment of this invention. It is a perspective view which looked at the blower of FIG. 1 from another angle. It is a figure which looked at the user who attached the blower of FIG. 1 from the back side. It is a side view which shows the mounting state of the blower of FIG. It is a perspective view which shows the process of attaching the blower of FIG. 1 to the attachment belt. It is a perspective view which shows the state which the blower of FIG. 1 is attached to the attachment belt.

Hereinafter, embodiments of the present invention will be illustrated and described with reference to the drawings. The blower device 1 shown in FIGS. 1 to 4 includes a main body portion 2, a mounting portion 3, and a holding portion 4, and can be detachably attached to the upper body of the user.

The main body 2 has a cylindrical shape, and has a discharge port 2a located on one side (upper side in FIG. 1) in the axial direction along the central axis C and an intake port 2b located on the other side (lower side in FIG. 1). Have. The discharge port 2a opens toward one side in the axial direction of the main body 2, and the intake port 2b opens in a direction inclined with respect to the axial direction of the main body 2.

In this example, the intake port 2b is configured to face the opposite side (outside) of the user's body when worn by the user (see FIGS. 3 and 4). The main body portion 2 has an upper straight portion 2d extending straight and a curved portion 2e connected below the straight portion 2d, a discharge port 2a is formed at the upper end of the straight portion 2d, and intake air is taken at the lower end of the curved portion 2e. The mouth 2b is formed. In this example, the central axis of the straight portion 2d is the central axis C of the main body portion 2.

A ventilation mechanism (not shown) is provided inside the main body 2. With this ventilation mechanism, the blower device 1 can take in air from the intake port 2b and send out the taken-in air from the discharge port 2a. The blower mechanism can be configured by, for example, a motor, a fan, or the like, but the specific configuration is not particularly limited. A push button type switch 2c for switching on / off of the ventilation mechanism is provided on the outer surface of the main body 2. The switch 2c is provided below the hinge portion 6. As a result, the switch 2c can be easily operated because the hem of the upper garment J is exposed below the upper garment J even when the hem of the upper garment J is sandwiched between the main body portion 2 and the holding portion 4 (see FIG. 4).

Further, a power source such as a rechargeable battery is connected to the ventilation mechanism of the main body 2. The power supply may be provided inside the main body 2 or outside the main body 2. In this example, as shown in FIG. 2, the power supply can be connected via the cable 5 arranged on the mounting portion 3 side.

The mounting portion 3 is provided on the outside of the main body portion 2 and is configured to be held by the upper body above the position of the waist belt of the user. The mounting portion 3 of this example is fixed to the outer peripheral surface of the main body portion 2 on the side opposite to the direction of the intake port 2b.

As shown in FIGS. 3 and 4, the mounting portion 3 is mounted on a mounting belt 7 wrapped around the upper body above the waist belt position, separately from the user's waist belt B. In the mounting portion 3 of this example, the left and right hook portions 3a opened downward are inserted into the inside of the mounting belt 7 from above, so that the left and right hook portions 3a are sandwiched and held inside the mounting belt 7. It is composed.

The mounting portion 3 of this example is configured to be removable from the mounting belt 7. As a result, the ventilation device 1 can be attached to and detached from the attachment belt 7 without removing the attachment belt 7 from the user's body. Although the mounting portion 3 of this example is fixed to the main body portion 2, the mounting portion 3 may be detachably configured with respect to the main body portion 2.

Here, the mounting belt 7 is composed of, for example, as shown in FIG. 5, a band-shaped base portion 7a and a band-shaped braided portion 7b woven so as to alternately pass the front surface and the back surface with respect to the base portion 7a. can do. In this case, the hook portions 3a on both the left and right sides of the mounting portion 3 are inserted into the insertion hole portion 7c formed between the base portion 7a and the braided portion 7b located on the surface side of the base portion 7a for mounting. Can be done. With such a configuration, it is possible to regulate the movement of the blower device 1 mounted on the mounting belt 7 (movement along the extending direction of the mounting belt 7). The position of the blower 1 on the mounting belt 7 can be changed by pulling out the hook portion 3a of the mounting portion 3 from the insertion hole portion 7c and inserting it into a different insertion hole portion 7c. By providing ribs or the like on the inner surface (the surface on the user's body side) of the wearing belt 7, the air permeability between the wearing belt 7 and the body is enhanced, and the separation between the upper garment J and the blower 1 is suppressed. The effect can be enhanced.

The holding means for holding the blower 1 on the upper body of the user is not limited to the wearing belt 7, and may be, for example, a harness or a belt worn by hanging on both shoulders or one of the shoulders. Alternatively, the hook portion of the mounting portion 3 is not limited to the belt-shaped member, but is provided in a mounting hole (slit-shaped or pocket-shaped) provided on the inside of the upper garment J or on the outer surface of clothing such as a vest or shirt to be worn under the upper garment J. 3a may be inserted and attached, or may be attached to the inner surface of the upper garment J or the outer surface of the garment to be worn under the upper garment J with a surface fastener. Alternatively, an arm extending upward from the fixed portion attached to the waist belt B may be provided, and the blower device 1 may be attached to the tip of the arm so that the arm is held above the waist belt B.

The holding portion 4 is configured to be rotatable with respect to the main body portion 2 via the hinge portion 6. The rotation axis of the hinge portion 6 extends on a plane orthogonal to the axis of the main body portion 2 and is located on the opposite side of the mounting portion 3.

The holding portion 4 is pivotally supported by the hinge portion 6 and is opened to a position below the hinge portion 6 (see the two-dot chain line in FIG. 4), and the hinge portion 6 is pulled up to the fulcrum and shown in FIG. It can be rotated until it is closed. In the closed state shown in FIG. 1, the holding portion 4 is arranged along the outer peripheral surface so as to cover the outer peripheral surface of the straight portion 2d of the main body portion 2 by more than half in the circumferential direction.

As shown in FIG. 1, the holding portion 4 of this example includes an upper frame 4a curved in a substantially arc shape extending along the outer peripheral surface of the main body portion 2 at a position separated from the hinge portion 6, and the upper frame 4a. It has left and right vertical frames 4b extending from both ends in the axial direction, and a lower frame 4c extending from the lower end of each vertical frame 4b to the hinge portion 6.

The holding portion 4 is configured to cover the outer peripheral surface of the straight portion 2d of the main body portion 2 from the front side to the side of the main body portion 2 over a half or more in the circumferential direction. That is, since the holding portion 4 is configured to surround the outer peripheral surface of the straight portion 2d over half a circumference or more, the upper garment has a wider range than, for example, the case where the hem of the upper garment J is sandwiched only by one side of the main body portion 2. Since J is sandwiched, the upper garment J can be strongly held, and the effect of preventing the exposure of the discharge port 2a can be enhanced.

The holding portion 4 is made of an elastically deformable material such as polyacetal resin. Further, the distance between the left and right vertical frames 4b is set to be smaller than the diameter of the main body 2, and the width of the left and right vertical frames 4b is temporarily expanded when the holding portion 4 is attached to and detached from the main body 2. It is configured as follows. Then, by fitting the holding portion 4 into the main body portion 2 (undercut engagement) in the closed state, the hem of the upper garment J can be strongly sandwiched and made difficult to come off. The material and shape of the holding portion 4 can be changed as appropriate.

When the blower 1 is attached to the user, the attachment belt 7 is attached to the upper body, and then the hook portion 3a of the attachment portion 3 is inserted into the inside of the attachment belt 7 to attach the blower 1 to the upper body of the user. Can be retained. After that, as shown by the alternate long and short dash line in FIG. 4, the holding portion 4 is opened, and the hem of the upper garment J is arranged between the main body portion 2 and the holding portion 4. Then, the holding portion 4 is pulled up and the hinge portion 6 is rotated around the fulcrum, and the holding portion 4 is pushed into the main body portion 2 until the holding portion 4 is in the closed state shown by the solid line in FIG. It can be strongly sandwiched and held between the holding portion 4 and the holding portion 4.

When the blower mechanism is driven in this state, the air taken in from the intake port 2b is sent out from the discharge port 2a to the inside of the upper garment J. When air passes along the user's body inside the upper garment J, the sweat of the body is easily vaporized, and the cooling effect when the sweat is vaporized (evaporated) can promote a decrease in body temperature. Further, by discharging the air inside the upper garment J whose humidity has increased due to the vaporization of sweat to the outside, the space inside the upper garment J becomes a comfortable environment in which the sweat is always easily vaporized.

Here, for example, a large number of waist bags and tool holders for carrying tools and tools are often passed through the waist belt B of a worker who works at a construction site or a construction site, and a blower device. When 1 is to be attached to the waist belt B, the waist bag, the tool holder, etc. must be moved to either the left or right side for use. In this case, the position of the tools may change from the original arrangement, which may impair workability. Further, for example, when a large waist bag is attached to the waist belt B directly behind the user and an attempt is made to attach the blower device 1 to the waist belt B, the blower device 1 is attached to the center of the back. I couldn't do it, so I had to put it closer to either the left or right side. Therefore, there is a possibility that the cooling effect cannot be sufficiently obtained due to the imbalance of the wind sent into the upper garment.

On the other hand, in the blower device 1 of the present embodiment, the blower device 1 can be held above the waist belt position by using a mounting belt 7 different from the waist belt B. Therefore, it is not necessary to change the positions of the waist bag and the tool holder attached to the waist belt B, and the arrangement of the tools that is easy for the operator can be maintained. Further, since the blower device 1 is located on the upper body above the waist belt B, it is possible to prevent the blower device 1 from obstructing the removal of the tool from the waist bag or the tool holder.

Further, in the blower device 1 of the present embodiment, since the blower device 1 is mounted on a mounting belt 7 different from the waist belt B, there are few restrictions on the mounting position of the blower device 1, and the position is desired. The blower 1 can be arranged. As a result, the blower 1 can be arranged on the center side of the back where the cooling effect is high, and the decrease in the cooling effect can be suppressed.

Further, in the blower device 1 of the present embodiment, since it is attached to the upper body above the waist belt position, the blower device 1 follows the movement of the upper body. Therefore, the positional deviation between the blower device 1 and the upper garment J is less likely to occur as compared with the case where the waist belt B is attached. Therefore, even if the user crouches or bends forward, the discharge port 2a is less likely to be exposed to the outside of the upper garment J, and the cooling function can be continuously exerted. Further, since the blower device 1 is arranged above the waist belt position, for example, even if the length of the upper garment J is short, the discharge port 2a side of the blower device 1 can be covered with the upper garment J with a margin.

Further, in the blower device 1 of the present embodiment, by strongly sandwiching the hem of the upper garment J with the holding portion 4, it is possible to more reliably prevent the position shift between the blower device 1 and the upper garment J. As a result, the exposure prevention effect of the discharge port 2a can be enhanced.

In particular, in the blower device 1 of the present embodiment, the upper frame 4a of the holding portion 4 sandwiches the upper garment J in the front-rear direction, and the left and right vertical frames 4b sandwich the upper garment J in the left-right direction. Therefore, in the mounted state, the hem of the upper garment J is sandwiched between the main body portion 2 and the holding portion 4 in the folded state, and the upper garment J can be strongly held.

When the blower 1 is attached to the waist belt B and the hem of the upper garment J is sandwiched between the holding portions 4, the upper garment J is pulled backward by the blower 1 when the user crouches or bends forward. This may hinder the user's operation, but there is no such risk because the blower device 1 is attached above the waist belt position.

Further, in the blower device 1 of the present embodiment, the intake port 2b is opened in a direction inclined with respect to the axial direction of the main body portion 2. This makes it possible to prevent the intake port 2b from being blocked by, for example, a tool attached to the waist belt B below the blower device 1. As a result, the air intake can be reliably performed when the blower device 1 is operated, so that the cooling function can be reliably exerted. As described above, from the viewpoint of enhancing the performance of the intake air, it is preferable that the intake port 2b faces the opposite side (outside) of the user's body in the wearing state of the user as in this example.

Although described above based on the illustrated examples, the present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the claims, for example, the main body 2. The direction of the intake port 2b may be either left or right in the mounted state, or may be upward or downward. Further, the holding portion 4 may be made of a plate-shaped or linear metal member or a composite material such as carbon fiber. Further, the holding portion 4 may be configured to be removable from the main body portion 2, and in that case, it is preferable to provide a fall prevention function by connecting the main body portion 2 and the holding portion 4 with a string or the like. The blower device 1 may be configured not to include the holding portion 4, in which case the discharge port 2a of the main body portion 2 is arranged inside the upper garment J and the intake port 2b is exposed below the upper garment. , Only the upper part of the blower device 1 is covered with the upper garment J. Further, the blower device 1 may be configured to be provided with a holding means such as a mounting belt 7 which is held on the upper body of the user and on which the blower device 1 can be attached. That is, the blower device 1 may be a blower device 1 with a holding means.
