Description

The present invention relates to the technology of clothing air blowers, and more specifically to clothing air blowers that are attached to openings in the fabric of clothing that covers at least a portion of the body.

Conventionally, there are known configurations of clothing air blowers that are attached to openings in the fabric of clothing that covers at least part of the body. This type of clothing air blower is configured as a fan unit that is arranged at multiple locations on the fabric and rotates the fan in a direction that draws outside air into the fabric while the clothing is being worn. This blows the outside air sucked into the fabric between the fabric and the body, circulating it along the surface of the body and removing the heat of evaporation from the body, cooling it.

Conventional clothing air blowers, as disclosed in Patent Documents 1 and 2, for example, have proposed a structure in which an annular mounting member is detachably attached to the cylindrical portion of the device body that houses the fan, and the mounting member is attached so as to sandwich the clothing material (the edge of the opening) between the mounting member and the flange portion of the device body. Specifically, Patent Document 1 discloses a screw-type mounting structure in which the annular mounting member is threadedly engaged with a male screw engraved on the outer peripheral surface of the cylindrical portion of the device body, while Patent Document 2 discloses an engagement-type mounting structure in which a protrusion on the mounting member engages with a recess formed on the outer peripheral surface of the device body.

However, in the configuration of the above-mentioned conventional clothing air blower, the screw-type mounting structure disclosed in Patent Document 1 requires the mounting member to be fastened by biting into the clothing fabric, which requires effort when attaching and detaching the mounting member from the device body, and it is also necessary to position the mounting direction of the device body when attaching the air blower to clothing. On the other hand, the engagement-type mounting structure disclosed in Patent Document 2 requires the projection of the mounting member to engage with the corresponding recess in the device body, which requires the mounting direction of the mounting member to be aligned with the device body when attaching it to the device body.

The present invention aims to solve the above-mentioned problems with clothing air blowers, and to provide a clothing air blower that allows the attachment member to be easily attached and detached from the device body.

The above is the problem that this invention aims to solve, and next we will explain the means for solving this problem.

That is, in claim 1, a clothing air blower attached to an opening provided in the fabric of clothing that covers at least a part of the body comprises a device main body having a fan housed inside and a flange portion protruding from one end of a cylindrical tubular portion inserted into the opening, and a locking rib portion protruding radially from the outer circumferential surface of the tubular portion at a distance from the flange portion; an annular band portion with ends, which is detachably attached to the tubular portion of the device main body and formed into a ring shape by bending both ends of an elongated body in a direction that brings them closer to each other ; and a connecting member for connecting the ends of the band portion. and an attachment member consisting of a fastening portion, and the attachment member is configured to wrap the belt around the outer circumferential surface of the tubular portion of the device body, with the belt positioned between the flange portion and the locking rib portion along the outer circumferential surface of the tubular portion, by switching from an open state in which both ends of the belt are not connected to a connected state in which both ends of the belt are connected at the connecting portion , and sandwiching the fabric between the periphery of the belt and the flange portion, and abutting the periphery of the belt on the side opposite to the side facing the flange portion against the locking rib portion .

In claim 2, the attachment member has a flexible strap portion, and when the ends of the strap portion are connected at the connecting portion, an elastic force is generated in the direction in which the ends of the strap portion expand.

In claim 3, the band portion has a stepped recess on the periphery opposite the side facing the flange portion that can engage with the locking rib portion.

In claim 4, the band portion is provided with an auxiliary protrusion that protrudes radially from the periphery on the side facing the flange portion.

In claim 5, the mounting member has a flexible connecting portion and is composed of a connecting piece disposed at one end of the belt portion and a connecting bracket disposed at the other end of the belt portion and with which the connecting piece engages.

One of the advantages of this invention is that the attachment member can be easily attached and detached from the device body.

Next, we will explain how to implement the invention. Note that in the following examples, the direction of arrow X in Figure 7 corresponds to the vertical direction (axial direction) of the blower 1.

First, the configuration of the garment 100 in which the air blower 1 of this embodiment is used will be outlined below.
1 and 2, the air blower 1 of this embodiment is configured as an air blower for clothing that is attached to an opening 3 provided in a fabric 2 of a garment 100 that covers at least a portion of the body. The garment 100 of this embodiment is formed as long-sleeved work clothing that covers the upper half of the body using the fabric 2, and is composed of the air blower 1 disposed in the opening 3 opened in the fabric 2, a power supply 4 as a driving power source for the air blower 1, and the like. When the air blower 1 is driven while the garment 100 is worn on the body, outside air is introduced into the fabric 2 and blown between the fabric 2 and the body, and the air that has entered the fabric 2 is circulated along the surface of the body, thereby cooling the body.

The fabric 2 not only serves as clothing that covers the body, but also as an air guide that guides the air generated by the air blower 1 along the surface of the body. The fabric 2 is provided with a zipper 5 as an opening and closing means on the front part 2a and an elastic drawstring 6 on the hem 2b. When the front of the fabric 2 is closed with the zipper 5, the air introduced into the fabric 2 by the air blower 1 is prevented from leaking out from the front part 2a and sleeves 2b, and is instead discharged out from the cuffs 2c and collar 2d.

Openings 3 are formed at the rear 2e of the fabric 2 in symmetrical positions below, and air blowers 1, described below, are attached to each of the left and right openings 3. By arranging the air blowers 1 at symmetrical positions on the rear 2e in this way, the air blowers 1 do not get in the way when the wearer is seated or working, and the air blowers 1 are not visible from the front, which improves the appearance. Furthermore, the air blowers 1 allow the air drawn into the fabric 2 to be distributed widely over the body before being expelled from the cuffs 2c and collar 2d.

A pocket 7 for storing the power supply unit 4 is provided on the back of the fabric 2, and in this embodiment, the pocket 7 is located on the back surface of the front portion 2a. The power supply unit 4 stored in the pocket 7 is connected to the air blower 1 attached to the opening 3 described above via a power supply cable 8 fixed to the back surface of the rear portion 2e so as to be able to supply power.

The material used for the fabric 2 is preferably one that smoothly guides the air generated by the air blower 1 along the surface of the body and prevents the air from leaking to the outside.

As shown in Figure 2, the opening 3 is a circular opening in the fabric 2 in a plan view, and the corresponding air blower 1 is attached to it. The inner diameter of the opening 3 is the same as or slightly larger than the outer diameter of the tubular portion 16 of the air blower 1, which will be described later. When attaching the air blower 1 to the opening 3, the tubular portion 16 of the device body 10 is inserted into the opening 3 from the front side of the fabric 2, and the attachment member 20 is attached to the tubular portion 16 of the device body 10 from the back side of the fabric 2, so that the fabric 2 (opening edge 3a of the opening 3) is sandwiched between the flange portion 17 of the device body 10 and the band portion 21 of the attachment member 20 (see Figure 5, etc.).

The power supply device 4 is configured as a power source supplied to the air blower 1, and is connected to the air blower 1 via a power cable 8 so that power can be supplied. The power supply device 4 has a built-in secondary battery such as an alkaline battery (not shown), a nickel-metal hydride battery, or a lithium-ion battery, and is configured so that the power supply to the air blower 1 can be controlled by a switch that turns the power supply on and off. It may also be configured so that the operation of the air blower 1 can be controlled, for example, by adjusting the air volume or using a timer.

Next, the configuration of the blower device 1 of this embodiment will be described in detail below.
3 to 10, the blower 1 of this embodiment is composed of a device main body 10 that houses a fan 12 and a motor 13 as a drive source for the fan 12, and a mounting member 20 that is detachably attached to a cylindrical portion 16 of the device main body 10. The blower 1 of this embodiment employs a wrap-type mounting structure in which a band portion 21 of the mounting member 20 is wrapped around the outer circumferential surface 16a of the cylindrical portion 16 of the device main body 1, as will be described later.

The device main body 10 is composed of a housing 11 made of a synthetic resin material. Inside the housing 11, there is a fan 12, which is a propeller fan with multiple blades, and a motor 13, which is the drive source for the fan 12. In this embodiment, the housing 11 is formed by combining two upper and lower members together, and is composed of an inlet section 14, an outlet section 15, and a cylindrical section 16 that connects the periphery of the inlet section 14 and the periphery of the outlet section 15 vertically.

The inlet section 14 is formed with a convex surface that bulges downward (toward the bottom of the paper in Figure 7), and has a number of intake-side vents 14a, 14a... that are separated radially from the center. In the device main body 10, when the fan 12 is driven to rotate, air (outside air) flows into the housing 11 through the vents 14a, 14a... of the inlet section 14.

The exhaust section 15 is formed in a dome shape that bulges upward (toward the top of the paper in Figure 7), with the periphery of the generally flat top gradually bending upward to connect to the cylindrical section 16, and multiple exhaust-side vents 15a, 15a... are opened radially from the center of the top. In the device main body 10, when the fan 12 is driven to rotate, air inside the housing 11 is exhausted to the outside of the device through each of the vents 15a, 15a... of the exhaust section 15.

The exhaust section 15 has the above-mentioned fan 12 and motor 13 arranged inside the housing 11, and a power receiving connector (not shown) that connects to the power supply cable 8 is arranged with its socket facing outward from the housing 11.

The tubular portion 16 is formed as a hollow cylinder with a circular cross section perpendicular to the central axis, and is configured so that the outer circumferential surface 16a has a constant diameter along the vertical direction. The tubular portion 16 is connected to the inlet portion 14 at one end and to the outlet portion 15 at the other end, and air flowing in through the vent 14a of the inlet portion 14 flows through the internal space of the tubular portion 16 to the vent 15a of the outlet portion 15.

The cylindrical portion 16 is provided with a flange portion 17 protruding from one end of the cylindrical portion 16, and a locking rib portion 18 protruding radially from the outer surface 16a of the cylindrical portion 16 at a distance from the flange portion 17.

The flange portion 17 is disposed at one end of the cylindrical portion 16, which is continuous with the inlet portion 14, and protrudes from the outer surface 16a of the cylindrical portion 16 in a direction perpendicular to the axial direction (radial direction), and is formed so that the thickness is approximately constant around the entire outer surface 16a (see Figure 4, etc.). The flange portion 17 abuts against the surface of the fabric 2 when the air blower 1 is attached to the opening 3 (see Figures 5 to 7, and Figure 8, etc.).

The locking rib portions 18 are arranged at one end of the tubular portion 16, which is continuous with the discharge portion 15, at a vertical distance from the flange portion 17. They protrude radially from the outer surface 16a of the tubular portion 16 and are arranged at multiple locations (four locations in this embodiment) around the outer surface 16a at equal intervals on the same plane (see Figure 4, etc.). When the blower 1 is attached to the mounting opening 3, the locking rib portions 18 abut against the band portion 21 (step recess 23) of the mounting member 20 (see Figures 5 to 7, 8(a), etc.).

The locking rib portion 18 is formed so that its protruding length from the outer peripheral surface 16a is shorter than the protruding length of the flange portion 17, and is set to a length that allows the mounting member 20 to be engaged, at least when the mounting member 20 is attached to the tubular portion 16 of the device body 10. By setting the protruding length of the locking rib portion 18 in this manner, workability is not impaired when attaching or detaching the air blower 1 to or from the opening 3, i.e., when inserting or removing the tubular portion 16 from the opening 3, or when attaching or detaching the mounting member 20 from the tubular portion 16 (see Figure 10, etc.).

The device body 10 of this embodiment is configured so that the distance between the flange portion 17 and the locking rib portion 18 is longer than the vertical length of the belt portion 21 of the attachment member 20 (described below), allowing the attachment member 20 to be securely positioned in the gap between the flange portion 17 and the locking rib portion 18. In particular, in this embodiment, the distance between the flange portion 17 and the locking rib portion 18 is longer than the vertical length from the bottom surface of the stepped recess 23 of the belt portion 21 to one end of the belt portion 21 where the auxiliary protrusion 24 is located. The distance between the flange portion 17 and the locking rib portion 18 is set appropriately depending on the vertical length of the belt portion 21 of the attachment member 20 and the thickness of the fabric 2 (opening edge 3a of the opening 3), etc.

The mounting member 20 is detachably attached to the tubular portion 16 and includes a ring-shaped band portion 21 formed from a long, circular body, and a connecting portion 22 connecting both ends 21a of the band portion 21. In this embodiment, the mounting member 20 is made of synthetic resin, with the band portion 21 and connecting portion 22 integrally formed, and the band portion 21 and connecting portion 22 are configured to be flexible (see Figures 5 to 10, etc.).

The belt portion 21 is formed from a long, plate-like body of a predetermined thickness, and is formed into a circular, end-ended ring shape in a plan view by bending both ends 21a toward each other. The upper and lower end faces of the belt portion 21 are formed as smooth, parallel surfaces. When the air blower 1 is attached to the opening 3, one end face abuts against the back surface of the fabric 2, and the other end face (the end face of the stepped recess 23) abuts against the locking rib portion 18.

The band portion 21 has a stepped recess 23 on the periphery opposite the side facing the flange portion 17 that can engage with the locking rib portion 18. The stepped recesses 23 are recessed into the periphery of the band portion 21 and are arranged at multiple equally spaced locations (four locations in this embodiment) around the periphery of the band portion 21, corresponding to the locking rib portion 18 (see Figure 4, etc.). The stepped recesses 23 abut and engage with the locking rib portion 18 when the blower 1 is attached to the opening 3 (see Figures 5 to 7, and Figure 8(a)).

The belt portion 21 is provided with auxiliary protrusions 24 that protrude radially from the periphery on the side opposite the flange portion 17. The auxiliary protrusions 24 protrude left and right from the outer surface of the belt portion 21 and are arranged at multiple locations (three locations in this embodiment) along the circumferential direction of the outer surface of the belt portion 21 at predetermined intervals on the same plane (see Figure 4, etc.). When the air blower 1 is attached to the opening 3, the auxiliary protrusions 24 abut against the back surface of the fabric 2, continuing from the belt portion 21 (see Figures 5 to 7, and Figure 8(b)).

The connecting portion 22 is composed of a connecting piece 25 disposed at one end 21a of the belt portion 21 and a connecting bracket 26 disposed at the other end 21a of the belt portion 21 and with which the connecting piece 25 engages. The connecting piece 25 is formed by bending a plate-like body into a roughly U-shape, with the curved portion 25a protruding from the end 21a of the belt portion 21 and the free end 25b not fixed to the belt portion 21, protruding from the outer surface of the belt portion 21. The connecting bracket 26 is formed in a roughly rectangular parallelepiped shape and protrudes radially from the outer surface of the belt portion 21, with a connecting hole 26a opened on the side facing the connecting piece 25, into which the curved portion 25a of the connecting piece 25 is inserted.

The connecting piece 25 of the connecting portion 22 is flexible, allowing the free end 25b to deform in a direction approaching the band portion 21 under stress load conditions. That is, when the curved portion 25a of the connecting piece 25 is inserted into the connecting hole 26a of the connecting bracket 26, the connecting piece 25 is deformed in a direction bringing the free end 25b closer to the band portion 21. Furthermore, the elastic force (restoring force) of the connecting piece 25 presses the free end 25b against the connecting bracket 26 within the connecting hole 26a, thereby engaging the connecting piece 25 and the connecting bracket 26 (see Figures 9 and 10, etc.).

In this embodiment, the mounting member 20 can be switched between a state in which both ends 21a of the band portion 21 are positioned apart (open state), and a state in which both ends 21a of the band portion 21 are closely connected at the connecting portion 22 until they nearly abut (connected state) (see Figures 9 and 10, etc.). When switched from the open state to the connected state, the band portion 21 is flexible and easily deforms in a direction that reduces its diameter under stress load conditions. In the connected state, a bending load acts on the band portion 21, causing it to elastically compress, generating an elastic force (restoring force) in a direction that expands both ends 21a.

In addition, the mounting member 20 of this embodiment is formed so that the band portion 21 is circular in plan view in either the open state or the connected state, and is formed so that at least the inner diameter of the band portion 21 is longer than the outer diameter of the tubular portion 16 of the device main body 10 described above (see Figure 10, etc.). In this embodiment, the band portion 21 is deformed in a direction that reduces its diameter in the connected state compared to the open state, so the inner diameter of the band portion 21 in the connected state is shorter than the inner diameter of the band portion 21 in the open state.

Here, a method for attaching the air blower 1 to the opening 3 of the fabric 2 will be described below.
As shown in Figures 2, 3, 11 and 12, when the blower device 1 of this embodiment is attached to the opening 3, the tubular portion 16 of the device body 10 is first inserted into the opening 3 from the surface of the fabric 2, and then pushed forward until the flange portion 17 abuts against the surface of the fabric 2, causing the discharge portion 15 and the tubular portion 16 to protrude toward the back side of the fabric 2 (see Figure 2).

Next, the attachment member 20, in an open state with both ends 21a of the belt portion 21 positioned with a gap between them, is brought close to the device main body 10 from the back side of the fabric 2, with the tubular portion 16 inserted into the opening 3 of the fabric 2, and the tubular portion 16 of the device main body 10, protruding from the back side of the fabric 2, is inserted into the space formed by the belt portion 21 (see Figures 2 and 11). At this time, the attachment member 20 is pushed forward until the belt portion 21 and auxiliary protrusions 24 abut against the back side of the fabric 2, and the belt portion 21 is positioned along the outer surface 16a of the tubular portion 16 of the device main body 10 (see Figure 12).

Then, the mounting member 20 is operated to deform the band portion 21 in a direction reducing its diameter so that both ends 21a approach each other until they substantially abut. The stepped recess 23 of the band portion 21 is aligned with the locking rib 18 of the tubular portion 16, and the curved portion 25a of the connecting piece 25 is inserted into the connecting hole 26a of the connecting bracket 26 to engage the connecting piece 25 with the connecting bracket 26. In this way, the mounting member 20 is switched from the open state to the connected state in which both ends 21a of the band portion 21 are connected by the connecting portion 22, and the band portion 21 of the mounting member 20 is attached by wrapping it around the outer circumferential surface 16a of the tubular portion 16, thereby attaching the blower 1 to the opening 3 (see Figure 3).

When the air blower 1 is attached to the opening 3 and the mounting member 20 is attached to the tubular portion 16, the fabric 2 (opening edge 3a of the opening 3) is sandwiched between the flange portion 17 of the device body 10 and the belt portion 21 and auxiliary protrusion portion 24 of the mounting member 20. Furthermore, when the mounting member 20 is connected, the stepped recess 23 of the belt portion 21 abuts and engages with the locking rib portion 18. This prevents the device body 10 from detaching from the fabric 2 (opening edge 3a of the opening 3) (see Figure 7, etc.).

In this embodiment, the air blower 1 is positioned so that the mounting member 20 cannot rotate relative to the main body 10 because the locking rib 18 engages with the stepped recess 23 of the belt 21. However, the air blower 1 itself attached to the opening 3 is not fixed in position relative to the fabric 2 (opening edge 3a of the opening 3), but is arranged to be rotatable around the axis of the main body 10.

On the other hand, removing the air blower 1 from the opening 3 in the fabric 2 can be done by reversing the procedure of the above-described attachment method. However, because the connected attachment member 20 generates an elastic force (restoring force) in the direction that causes both ends 21a of the belt portion 21 to expand, simply by pulling the connecting piece 25 out of the connecting hole 26a of the connecting bracket 26 and opening the connecting portion 22, the attachment member 20 can be immediately returned to a state in which both ends 21a of the belt portion 21 are positioned apart (open state), making it easy to remove the attachment member 20 from the tubular portion 16.

As described above, the air blower 1 of this embodiment is attached to an opening 3 provided in the fabric 2 of a garment 100 that covers at least a portion of the body, and includes an apparatus main body 10 that houses a fan 12 and has a flange portion 17 protruding from one end of a cylindrical tubular portion 16 that is inserted into the opening 3, and a locking rib portion 18 that protrudes radially from the outer circumferential surface 16a of the tubular portion 16 and is spaced apart from the flange portion 17, and a long, annular body that is detachably attached to the tubular portion 16 of the apparatus main body 10. The attachment member 20 is provided with an annular belt portion 21 with an end and a connecting portion 22 that connects the end 21a of the belt portion 21. The belt portion 21 is positioned along the outer surface 16a of the tubular portion 16 of the device main body 10, between the flange portion 17 and the locking rib portion 18, and the end 21a of the belt portion 21 is connected by the connecting portion 22, so that the fabric is sandwiched between the flange portion 17 and the attachment member 20, making it easy to attach and detach the attachment member 20 to and from the device main body 10.

In other words, the air blower 1 of this embodiment includes an attachment member 20 having an annular band 21 with an end and a connecting portion 22 connecting the ends 21a of the band 21. With the band 21 positioned between the flange 17 and the locking rib 18 along the outer circumferential surface 16a of the tubular portion 16 of the device body 10, the attachment member 20 can be switched between an open state in which both ends 21a of the band 21 are spaced apart, and a connected state in which both ends 21a of the band 21 are closely connected to the connecting portion 22 until they nearly abut. This allows the attachment of the band 21 of the attachment member 20 by wrapping it around the outer circumferential surface 16a of the tubular portion 16. Furthermore, the attachment member 20 can be easily removed from the tubular portion 16. Furthermore, since there is no need to position the device body 10 or the attachment member 20, the attachment member 20 can be easily attached and detached.

In particular, the attachment member 20 of the device main body 1 of this embodiment has a flexible strap portion 21, and when the end 21a of the strap portion 21 is connected by the connecting portion 22, an elastic force is generated in the direction in which the end 21a of the strap portion 21 expands. Therefore, simply by releasing the connecting portion 22, the attachment member 20 can be switched to an open state in which the end 21a of the strap portion 21 is positioned with a gap between them, making it easy to remove the attachment member 20.

In addition, the band portion 21 of the blower 1 of this embodiment is provided with a stepped recess 23 on the periphery opposite the side facing the flange portion 17 that can engage with the locking rib portion 18. This allows the mounting member 20 to be positioned non-rotatably relative to the device body 10 when the blower 1 is attached to the opening 3, preventing the connecting portion 22 from accidentally switching to an open state due to rotation of the mounting member 20 or damage to the connecting portion 22, etc.

In addition, the belt portion 21 of the air blower 1 of this embodiment is provided with an auxiliary protrusion 24 that protrudes radially from the periphery on the side opposite the flange portion 17. This allows the fabric 2 to be sandwiched between the flange portion 17 and the belt portion 21 and the auxiliary protrusion 24 on the mounting member 20, preventing tilting or rattling of the air blower 1 relative to the fabric 2 and allowing the air blower 1 to be attached more stably.

In addition, the mounting member 20 of the blower device 1 of this embodiment has a flexible connecting portion 22 and is composed of a connecting piece 25 arranged on one end 21a of the belt portion 21 and a connecting bracket 26 arranged on the other end 21a of the belt portion 21 and to which the connecting piece 25 engages.This means that the connecting piece 25 can be easily engaged and disengaged from the connecting bracket 26, and the mounting member 20 can be easily switched between an open state in which both ends 21a of the belt portion 21 are positioned apart, and a connected state in which both ends 21a of the belt portion 21 are connected closely together at the connecting portion 22 until they nearly abut.

The configuration of the blower 1 is not limited to the above-described embodiment, and various modifications are possible without departing from the scope of the present invention.

In other words, in the blower device 1 of the above-described embodiment, as shown in Figures 9 and 10, the band portion 21 is configured to be circular in plan view whether the mounting member 20 is in the open state or the connected state. However, it is sufficient that the mounting member 20 is configured so that at least the inner diameter of the band portion 21 is longer than the outer diameter of the tubular portion 16 of the device main body 10. For example, the band portion 21 may be configured to be approximately circular or elliptical in plan view.

In addition, in the blower device 1 of the above-described embodiment, the specific configurations of the engaging ribs 18 (four locations) provided on the tubular portion 16, the corresponding stepped recesses 23 (four locations) provided on the band portion 21 of the mounting member 20, and the auxiliary protrusions 24 (three locations) also provided on the band portion 21 have been described. However, the arrangement of the engaging ribs 18, stepped recesses 23, and auxiliary protrusions 24 is not limited to this, and any number or arrangement may be adopted in accordance with the objectives of the present invention.

In addition, in the present embodiment, the air blower 1 attached to the opening 3 is described as being configured so as not to be fixed in position relative to the fabric 2, but the attachment state of the air blower 1 is not limited to this, and it may be configured so that the attachment member 20 bites into the fabric 2 between the flange portion 17 and the attachment member 20, thereby fixing the position relative to the fabric 2 so that it cannot rotate.

In addition, in the above-described embodiment, the garment 100 is described as being configured as long-sleeved work clothing that covers the upper body using the fabric 2, but the configuration of the garment 100 is not limited to this, and it may be configured as clothing 100 that covers at least a portion of the body, and may be configured as, for example, short-sleeved clothing or a vest.
