Description

[Technical field]

[0001] The present invention relates to a technique for an air blowing device for clothing, and more particularly to an air blowing device for clothing that is attached to an opening provided in the fabric of clothing that covers at least a part of the body. [Background technology]

[0002] Conventionally, there has been known a configuration of a clothing air blower device that is attached to an opening provided in a fabric of clothing that covers at least a part of the body. This type of clothing air blower device is configured as a fan unit that is arranged at multiple locations on the fabric and rotates a fan in a direction that takes in outside air into the fabric while the clothing is being worn, thereby blowing the outside air sucked into the fabric between the fabric and the body and circulating it along the surface of the body to remove the heat of vaporization from the body and cool it.

[0003] Conventional clothing air blowing devices have been proposed, for example, in which an annular attachment member is detachably attached to a cylindrical portion of a device body that houses a fan, and the attachment member is attached so as to sandwich the clothing fabric (the edge of the opening) between the attachment member and a flange portion of the device body, as disclosed in Patent Documents 1 and 2. Specifically, Patent Document 1 discloses a screw-in type attachment structure in which the annular attachment member is screwed into a male screw threaded on the outer circumferential surface of the cylindrical portion of the device body, and Patent Document 2 discloses an engagement type attachment structure in which a protrusion of the attachment member is engaged with a recess formed on the outer circumferential surface of the device body.

[0004] However, in the above-mentioned conventional configuration of the clothing 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 mounting the mounting member to the device body and removing the mounting member from the device body, and the mounting direction of the device body needs to be positioned when attaching the blower to the clothing. On the other hand, the engagement-type mounting structure disclosed in Patent Document 2 requires the projection of the mounting member to be engaged with the corresponding recess of the device body, which requires the mounting direction of the mounting member to be aligned with the device body when mounting the mounting member to the device body.

[0015] Next, an embodiment of the invention will be described. In the following embodiment, the direction of arrow X in Fig. 7 corresponds to the up-down direction (axial direction) of blower 1.

[0016] First, the configuration of the garment 100 in which the air blower 1 of this embodiment is used will be generally described 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 part of the body. The garment 100 of this embodiment is formed as long-sleeved work clothing that covers the upper body with the fabric 2, and is configured with the air blower 1 disposed in the opening 3 opened in the fabric 2, a power supply unit 4 as a driving power source for the air blower 1, etc. 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 been introduced into the fabric 2 is circulated along the surface of the body, thereby cooling the body.

[0017] The fabric 2 not only serves as clothing that covers the body, but also as air guide means 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 at the front part 2a and a drawstring elastic 6 at the hem 2b, and is configured so that when the front of the fabric 2 is closed with the zipper 5, air flowed into the fabric 2 by the air blower 1 is prevented from leaking out from the front part 2a and sleeves 2b, and is discharged out from the cuffs 2c and collar 2d.

[0018] Openings 3 are formed at a pair of symmetrical left and right positions on the lower side of the rear part 2e of the fabric 2, and air blowers 1 (described later) are attached to the left and right openings 3, respectively. By disposing the air blowers 1 at a pair of symmetrical left and right positions on the rear part 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 look good because they cannot be seen from the front. Furthermore, the air blown into the fabric 2 by the air blowers 1 can be distributed widely over the body and then discharged from the cuffs 2c and collar 2d.

[0019] A pocket 7 for storing the power supply device 4 is provided on the back surface of the fabric 2, and in this embodiment, the pocket 7 is disposed so as to be located on the back surface of the front portion 2a. The power supply device 4 stored in the pocket 7 is connected to the blower device 1 attached to the opening 3 described above so as to be able to supply power thereto via a power supply cable 8 fixed on the back surface of the rear portion 2e.

[0020] The material of the fabric 2 is preferably one that smoothly guides the air generated by the air blower 1 along the surface of the body and does not allow the air to leak to the outside.

[0021] As shown in Fig. 2, the opening 3 is opened in a circular shape in a plan view in the fabric 2, and the corresponding air blower 1 is attached to it. The inner diameter of the opening 3 is formed to be the same as or slightly larger than the outer diameter of a tubular part 16 of the air blower 1 described later. When attaching the air blower 1 to the opening 3, the tubular part 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 part 16 of the device body 10 from the back side of the fabric 2, so that the fabric 2 (opening edge part 3a of the opening 3) is attached in a state where it is sandwiched between the flange part 17 of the device body 10 and the belt part 21 of the attachment member 20 (see Fig. 5, etc.).

[0022] 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 so as to be able to supply power via a power cable 8. The power supply device 4 has a built-in secondary battery such as an alkaline battery, nickel-metal hydride battery, or lithium-ion battery (not shown), and is configured so that the power supply to the air blower 1 can be controlled by a switch that switches the power supply to the air blower 1 on and off. The power supply device 4 may also be configured so that the operation of the air blower 1 can be controlled, for example, by adjusting the air volume or by using a timer.

[0023] Next, the configuration of the blower 1 of this embodiment will be described in detail below. 3 to 10, the blower 1 of this embodiment is composed of a device body 10 incorporating a fan 12 and a motor 13 as a drive source for the fan 12, and an attachment member 20 that is detachably attached to a cylindrical portion 16 of the device body 10. The blower 1 of this embodiment employs a wrap-around attachment structure in which a band portion 21 of the attachment member 20 is wrapped around an outer circumferential surface 16a of the cylindrical portion 16 of the device body 1, as described below.

[0024] The device main body 10 is composed of a housing 11 made of a synthetic resin material, and a fan 12 serving as a propeller fan having a plurality of blades, a motor 13 serving as a drive source for the fan 12, and the like are disposed within the housing 11. The housing 11 of this embodiment is formed by combining two upper and lower members integrally, and is composed of an inlet section 14, a discharge section 15, and a cylindrical section 16 that vertically connects the periphery of the inlet section 14 and the periphery of the discharge section 15.

[0025] Inlet section 14 is formed in a convex shape that bulges downward (downward on the paper in FIG. 7) and has a number of intake-side vent holes 14a that are defined radially from the center. In device body 10, air (outside air) flows into housing 11 from each of the vent holes 14a of inlet section 14 when fan 12 is driven to rotate.

[0026] Exhaust section 15 is formed in a dome shape bulging upward (upward on the paper in FIG. 7), with the periphery of the generally flat top portion gradually bending upward to connect to cylindrical section 16, and a large number of exhaust-side vent holes 15a... are defined radially from the center of the top portion. In device main body 10, air within housing 11 is exhausted to the outside from each of the vent holes 15a... of exhaust section 15 by driving fan 12 to rotate.

[0027] In the exhaust section 15, the above-mentioned fan 12 and motor 13 are arranged inside the housing 11, and a power receiving connector (not shown) that is connected to the power supply cable 8 is arranged with its socket facing the outside of the housing 11.

[0028] The tubular portion 16 is formed in a hollow cylindrical shape 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 ventilation hole 14a of the inlet portion 14 flows through the internal space of the tubular portion 16 to the ventilation hole 15a of the outlet portion 15.

[0029] The tubular portion 16 is provided with a flange portion 17 protruding from one end side of the tubular portion 16, and a locking rib portion 18 protruding radially from the outer circumferential surface 16a of the tubular portion 16 at a distance from the flange portion 17.

[0030] The flange portion 17 is disposed on one end side of the cylindrical portion 16 connected to the inlet portion 14, protrudes from the outer peripheral surface 16a of the cylindrical portion 16 in a direction perpendicular to the axial direction (radial direction), and is formed so as to have a substantially constant thickness all around the outer peripheral surface 16a (see FIG. 4, etc.). The flange portion 17 comes into contact with the surface of the fabric 2 when the blower 1 is attached to the opening 3 (see FIG. 5 to FIG. 7, and FIG. 8, etc.).

[0031] The locking rib portion 18 is disposed at one end side of the cylindrical portion 16 connected to the discharge portion 15 with a vertical gap from the flange portion 17, protrudes radially from the outer peripheral surface 16a of the cylindrical portion 16, and is disposed at a plurality of locations (four locations in this embodiment) along the circumferential direction of the outer peripheral surface 16a at equally spaced positions on the same plane (see FIG. 4, etc.). The locking rib portion 18 comes into contact with the belt portion 21 (step recess 23) of the mounting member 20 when the blower 1 is attached to the mounting opening 3 (see FIGS. 5 to 7, and FIG. 8(a) and others).

[0032] The locking rib portion 18 is formed so that the protruding length from the outer circumferential 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 locked at least in a state where the mounting member 20 is attached to the cylindrical 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 mounting and removing the blower device 1 to and from the opening 3, i.e., when inserting and removing the cylindrical portion 16 from the opening 3, and when attaching and removing the mounting member 20 from the cylindrical portion 16 (see FIG. 10, etc.).

[0033] The device body 10 of this embodiment is formed 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 later, and is configured so that the attachment member 20 can be reliably disposed in the space 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 formed so that it is longer than at least 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 portion 24 is disposed. The distance between the flange portion 17 and the locking rib portion 18 is appropriately set depending on the vertical length of the belt portion 21 of the attachment member 20 and the thickness of the fabric 2 (opening edge portion 3a of the opening 3), etc.

[0034] The mounting member 20 is detachably attached to the above-mentioned tubular portion 16, and is provided with a band portion 21 having an annular end formed by forming a long body into a ring shape, and a connecting portion 22 connecting both ends 21a of the band portion 21. In the mounting member 20 of this embodiment, the band portion 21 and the connecting portion 22 are integrally formed from a synthetic resin material, and the band portion 21 and the connecting portion 22 are configured to have flexibility (see Figs. 5 to 10, etc.).

[0035] The belt portion 21 is formed from a long plate-like body having a predetermined thickness, and is formed into a ring shape with ends that are circular in plan view by bending both ends 21a in a ring shape in a direction that brings them closer to each other. The belt portion 21 has upper and lower end faces that are formed as smooth surfaces that are parallel to each other, and when the 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.

[0036] The belt portion 21 is provided with a stepped recess 23 that can engage with the locking rib portion 18 on the periphery opposite to the side facing the flange portion 17. The stepped recesses 23 are recessed into the periphery of the belt portion 21 and are disposed at a plurality of locations (four locations in this embodiment) along the circumferential direction of the belt portion 21 at equal intervals in positions corresponding to the above-mentioned locking rib portion 18 (see FIG. 4, etc.). The stepped recesses 23 come into contact with and engage with the locking rib portion 18 when the blower 1 is attached to the opening 3 (see FIGS. 5 to 7, and FIG. 8(a) and others).

[0037] The belt portion 21 is provided with auxiliary projections 24 that protrude in the radial direction from the periphery of the side facing the flange portion 17. The auxiliary projections 24 protrude in the left-right direction from the outer circumferential surface of the belt portion 21, and are arranged at a predetermined interval on the same plane at multiple points (three points in this embodiment) along the circumferential direction of the outer circumferential surface of the belt portion 21 (see Fig. 4, etc.). The auxiliary projections 24 are continuous with the belt portion 21 and come into contact with the back surface of the fabric 2 when the air blower 1 is attached to the opening 3 (see Figs. 5 to 7, and Fig. 8(b)).

[0038] 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 engaged with the connecting piece 25. The connecting piece 25 is formed by bending a plate-like body into a substantially U-shape, and is provided on the outer circumferential surface of the belt portion 21 with a curved portion 25a protruding from the end 21a of the belt portion 21 and a free end 25b not fixed to the belt portion 21. The connecting bracket 26 is formed in a substantially rectangular parallelepiped shape and provided on the outer circumferential surface of the belt portion 21 in a radial direction, and has a connecting hole 26a opened on the surface facing the connecting piece 25, into which the curved portion 25a of the connecting piece 25 is inserted.

[0039] Since the connecting portion 22 has flexibility in the connecting piece 25, the free end 25b can be deformed under stress load conditions in a direction to approach the band portion 21. 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 to bring the free end 25b closer to the band portion 21, and the elastic force (restoring force) of the connecting piece 25 presses the free end 25b against the connecting bracket 26 in the connecting hole 26a, whereby the connecting piece 25 and the connecting bracket 26 are engaged with each other (see Figures 9 and 10, etc.).

[0040] The mounting member 20 of this embodiment can be switched between a state in which both ends 21a of the band portion 21 are positioned with a gap therebetween (open state) and a state in which both ends 21a of the band portion 21 are closely connected to each other at the connecting portion 22 until they substantially abut (connected state) (see Figs. 9 and 10, etc.). When the band portion 21 is switched from the open state to the connected state, it is flexible and easily deformed in a direction to reduce its diameter under stress load conditions, and in the connected state, it is elastically compressed by the action of a bending load, generating an elastic force (restoring force) in a direction in which both ends 21a expand.

[0041] Moreover, the mounting member 20 of this embodiment is formed so that the band portion 21 has a circular shape 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 FIG. 10, etc.). In this embodiment, the band portion 21 is deformed in a direction to reduce its diameter in the connected state compared to the open state, so that 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.

[0042] Here, a method for attaching the air blowing device 1 to the opening 3 of the fabric 2 will be described below. As shown in Figures 2, 3, 11 and 12, when the air blower 1 of this embodiment is attached to an opening 3, first, the tubular portion 16 of the device body 10 is inserted into the opening 3 from the surface side 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 to the back side of the fabric 2 (see Figure 2).

[0043] Next, the attachment member 20 in an open state with both ends 21a of the belt part 21 positioned with a gap therebetween is brought close to the device main body 10 with the tubular part 16 inserted into the opening 3 of the fabric 2 from the back surface of the fabric 2, and the tubular part 16 of the device main body 10 protruding from the back surface of the fabric 2 is inserted into the space formed by the belt part 21 (see Figs. 2 and 11). At this time, the attachment member 20 is pushed forward until the belt part 21 and the auxiliary protrusions 24 come into contact with the back surface of the fabric 2, and the belt part 21 is arranged along the outer circumferential surface 16a of the tubular part 16 of the device main body 10 (see Fig. 12).

[0044] Then, the mounting member 20 is operated to deform the band portion 21 in a direction of decreasing diameter so that both ends 21a approach each other until they substantially abut, and while aligning the stepped recess 23 of the band portion 21 to be positioned corresponding to the locking rib portion 18 of the tubular portion 16, 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 manner, the mounting member 20 is switched from the open state to a 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, whereby the blower 1 can be attached to the opening 3 (see FIG. 3).

[0045] When the blower device 1 is attached to the opening 3 and the mounting member 20 is attached to the tubular portion 16, the fabric 2 (the opening edge 3a of the opening 3) is sandwiched between the flange portion 17 of the device main body 10 and the belt portion 21 and auxiliary protrusion portion 24 of the mounting member 20, and when the mounting member 20 is in a connected state, the step recess 23 of the belt portion 21 abuts and engages with the locking rib portion 18, so that the device main body 10 will not detach from the fabric 2 (the opening edge 3a of the opening 3) (see Figure 7, etc.).

[0046] In the present embodiment, the step recess 23 of the belt portion 21 engages with the locking rib portion 18, so that the mounting member 20 is positioned non-rotatably relative to the device main body 10. However, the air blower 1 itself attached to the opening 3 is not fixed in position relative to the fabric 2 (the opening edge portion 3a of the opening 3), but is arranged so as to be freely rotatable around the axis of the device main body 10.

[0047] On the other hand, when removing the blower 1 from the opening 3 in the fabric 2, the procedure can be reversed from the above-mentioned mounting method; however, since the mounting member 20 in the connected state generates an elastic force (restoring force) in the direction in which both ends 21a of the belt portion 21 expand, the mounting member 20 can be immediately returned to a state in which both ends 21a of the belt portion 21 are positioned apart (open state) by simply pulling out the connecting piece 25 from the connecting hole 26a of the connecting bracket 26 and opening the connecting portion 22, so that the mounting member 20 can be easily removed from the tubular portion 16.

[0048] As described above, the air blower 1 of this embodiment is attached to an opening 3 provided in a fabric 2 of a garment 100 that covers at least a part of the body, and includes an apparatus main body 10 that houses a fan 12 therein and is provided with a flange portion 17 protruding from one end side of a cylindrical tubular portion 16 that is inserted into the opening 3 and a locking rib portion 18 that protrudes radially from an outer circumferential surface 16a of the tubular portion 16 and is spaced apart from the flange portion 17, and a long body that is formed into an annular shape and is detachably attached to the tubular portion 16 of the apparatus main body 10. The attachment member 20 comprises an annular belt portion 21 with ends, and a connecting portion 22 connecting the ends 21a of the belt portion 21, and an attachment member 20 provided with the connecting portion 22 connecting the ends 21a of the belt portion 21, with the belt portion 21 positioned between the flange portion 17 and the locking rib portion 18 along the outer circumferential surface 16a of the tubular portion 16 of the device main body 10, and the end 21a of the belt portion 21 connected by the connecting portion 22, so that the attachment member 20 is attached by sandwiching the fabric between the flange portion 17, thereby facilitating the attachment and detachment of the attachment member 20 to the device main body 10.

[0049] In other words, the air blower 1 of the present embodiment is equipped with an attachment member 20 having an annular band portion 21 with ends and a connecting portion 22 connecting the ends 21a of the band portion 21. With the band portion 21 positioned between the flange portion 17 and the locking rib portion 18 along the outer peripheral surface 16a of the tubular portion 16 of the device main body 10, the attachment member 20 can be switched between an open state in which both ends 21a of the band portion 21 are positioned with a gap therebetween, and a connected state in which both ends 21a of the band portion 21 are connected closely together until they nearly abut at the connecting portion 22. This allows the band portion 21 of the attachment member 20 to be attached by wrapping it around the outer peripheral surface 16a of the tubular portion 16, and the attachment member 20 can be easily removed from the tubular portion 16. Furthermore, since there is no need to position the device main body 10 or the attachment member 20, the attachment member 20 can be easily attached and detached.

[0050] In particular, in the mounting member 20 of the device main body 1 of this embodiment, the belt portion 21 is flexible, and when the end 21a of the belt portion 21 is connected at the connecting portion 22, an elastic force is generated in the direction in which the end 21a of the belt portion 21 expands. Therefore, by simply opening the connecting portion 22, the mounting member 20 can be switched to an open state in which the end 21a of the belt portion 21 is positioned with a gap between them, making it easy to remove the mounting member 20.

[0051] Furthermore, the band portion 21 of the blower device 1 in this embodiment is provided with a stepped recess 23 on the periphery opposite the side facing the flange portion 17, which can engage with the locking rib portion 18. Therefore, when the blower device 1 is attached to the opening 3, the mounting member 20 can be positioned relative to the device main body 10 so that it cannot rotate, and it is possible to prevent the connecting portion 22 from switching automatically to the open state due to the mounting member 20 rotating, etc., or to prevent the connecting portion 22, etc., from being damaged, etc.

[0052] In addition, the belt portion 21 of the air blower 1 in this embodiment is provided with an auxiliary protrusion 24 that protrudes radially from the periphery on the side opposite the flange portion 17, so that the fabric 2 can be clamped between the flange portion 17 and the belt portion 21 and the auxiliary protrusion 24 at the mounting member 20, preventing the air blower 1 from tilting or rattling relative to the fabric 2 and allowing the air blower 1 to be attached more stably.

[0053] In addition, the mounting member 20 of the blower device 1 in 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 with which the connecting piece 25 engages. Therefore, the connecting piece 25 can be easily engaged and disengaged with 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 with a gap between them, and a connected state in which both ends 21a of the belt portion 21 are connected closely to each other at the connecting portion 22 until they nearly abut.

[0054] 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.

[0055] That is, in the above-described embodiment of the blower 1, as shown in Figures 9 and 10, a configuration has been described in which the band portion 21 is formed to have a circular shape when viewed in a plan view whether the mounting member 20 is in the open state or the connected state. However, it is only necessary that the mounting member 20 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, and for example, the band portion 21 may be formed so as to have a substantially circular or elliptical shape when viewed in a plan view.

[0056] Furthermore, in the above-mentioned embodiment of the blower 1, the specific configurations of the engagement rib portions 18 (four locations) provided on the tubular portion 16 and the corresponding stepped recesses 23 (four locations) provided on the belt portion 21 of the mounting member 20, as well as the auxiliary protrusion portions 24 (three locations) also provided on the belt portion 21 have been described, but the arrangement of the engagement rib portions 18, stepped recesses 23 and auxiliary protrusion portions 24 is not limited to this, and any number or arrangement may be adopted in accordance with the purpose of the present invention.

[0057] Furthermore, in the embodiment of the air blower 1, the air blower 1 attached to the opening 3 is described as being configured not to be fixed in position relative to the fabric 2, but the mounting state of the air blower 1 is not limited to this, and the air blower 1 may be configured to be fixed in position relative to the fabric 2 so that it cannot rotate, by having the mounting member 20 bite into the fabric 2 between the flange portion 17 and the mounting member 20.

[0058] In addition, in the above-described embodiment, the garment 100 is described as being configured as long-sleeved work clothing covering the upper body using the fabric 2, but the configuration of the garment 100 is not limited to this, and it is sufficient that the garment 100 is configured as clothing that covers at least a portion of the body, and for example, it may be configured as short-sleeved clothing or a vest.
