Description

[Technical Field]

[0001] The present invention relates to a technique for a clothing air blower, and more particularly to a clothing air blower 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 have been known configurations of clothing air blowers attached to openings in the fabric of clothing that covers at least a portion of the body. These types of clothing air blowers are configured as fan units that are arranged at multiple locations on the fabric and rotate fans in a direction that draws outside air into the fabric while the garment is being worn, thereby blowing the outside air drawn into the fabric between the fabric and the body and circulating it along the surface of the body, removing the heat of vaporization from the body and cooling it.

[0003] Conventional clothing air blowing devices have been proposed, for example, in patent documents 1 and 2, in which an annular mounting member is detachably attached to a cylindrical portion of a device body that houses a fan, and the mounting member is attached so as to sandwich the clothing material (the edge of the opening) between the mounting member and a flange portion of the device body. Specifically, patent document 1 discloses a screw-type mounting structure in which the annular mounting member is screwed onto a male screw threaded on the outer peripheral surface of the cylindrical portion of the device body, and 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.

[0004] However, in the configuration of the conventional clothing air blower described above, the screw-type mounting structure disclosed in Patent Document 1 requires the mounting member to be fastened by biting into the clothing material, which requires effort when attaching and detaching the mounting member from the device body, and the mounting direction of the device body must be positioned before attaching the air 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 engage with the corresponding recess of the device body, which requires the mounting direction of the mounting member to be aligned with the device body before attaching the mounting member to the device body.

[0015] Next, an embodiment of the invention will be described. In the following embodiments, the direction of arrow X in Fig. 7 is the vertical direction (axial direction) of the blower 1.

[0016] 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 body with the fabric 2, and is composed of 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 flows into the fabric 2 and is blown between the fabric 2 and the body, and the air that has flowed 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 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, and is configured so that when the front of the fabric 2 is closed with the zipper 5, 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 discharged out from the cuffs 2c and collar 2d.

[0018] Openings 3 are formed at left and right symmetrical positions below the rear 2e of the fabric 2, and air blowers 1, which will be described later, are attached to each of the left and right openings 3. By arranging the air blowers 1 at left and right symmetrical positions on the rear 2e in this way, the air blowers 1 do not get in the way when the wearer is sitting or working, and the air blowers 1 look good because they cannot be seen from the front.Furthermore, the air blowers 1 allow the air to flow into the fabric 2 and be distributed widely over the body before being 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 arranged to be located on the back surface of the front part 2a. The power supply device 4 stored in the pocket 7 is connected to the air blower 1 attached to the opening 3 described above so as to be able to supply power via a power supply cable 8 fixed on the back surface of the rear part 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 prevents the air from leaking 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 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 portion 3a of the opening 3) is attached in a state where it is sandwiched between the flange portion 17 of the device body 10 and the band portion 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 via a power cable 8 so as to be able to supply power. 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 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 main body 10 that incorporates a fan 12, a motor 13 as a drive source for the fan 12, and the like, 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.

[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 multiple 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 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 in the vertical direction.

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

[0026] Exhaust section 15 is formed in a dome shape that bulges upward (upward on the paper surface in FIG. 7), with the periphery of its generally flat top gradually bending upward to connect to cylindrical section 16, and a large number of exhaust-side vent holes 15a radially extending from the center of the top are opened. In device main body 10, when fan 12 is driven to rotate, air inside housing 11 is exhausted to the outside of the device through each of the vent holes 15a in exhaust section 15.

[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 outward from the housing 11.

[0028] The cylindrical 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 diameter of the outer peripheral surface 16a is constant along the vertical direction. The cylindrical portion 16 is continuous with the inlet portion 14 at one end and with the outlet portion 15 at the other end, and air flowing in through the ventilation holes 14a of the inlet portion 14 flows through the internal space of the cylindrical portion 16 to the ventilation holes 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 peripheral 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 that is continuous with the inlet portion 14, and 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 that the thickness is approximately constant all around the outer peripheral surface 16a (see Figure 4, etc.). The flange portion 17 comes into contact with the surface of the fabric 2 when the air blower 1 is attached to the opening 3 (see Figures 5 to 7 and 8, etc.).

[0031] The locking rib portions 18 are arranged at one end of the cylindrical portion 16, which is continuous with the discharge portion 15, at a distance from the flange portion 17 in the vertical direction, and protrude radially from the outer peripheral surface 16a of the cylindrical portion 16, and are arranged 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 portions 18 come into contact with the band 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), etc.).

[0032] The locking rib portion 18 is formed so that the 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 attachment member 20 to be engaged, at least when the attachment 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 removing the attachment member 20 from the tubular 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, which will be described later, and is configured so that the attachment member 20 can be securely 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 24 is disposed. 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 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 an annular band portion 21 having ends 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 are configured so that the band portion 21 and the connecting portion 22 are flexible (see Figures 5 to 10, etc.).

[0035] The belt 21 is formed from a long, plate-like body having a predetermined thickness, and is formed into a circular, end-ended ring shape in a plan view by bending both ends 21a in a ring shape in a direction that brings them closer together. The upper and lower end faces of the belt 21 are formed as smooth surfaces that are parallel to each other, and 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 18.

[0036] The band portion 21 is provided with a stepped recess 23 on the periphery opposite to the side facing the flange portion 17, which 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 equal intervals at a plurality of locations (four locations in this embodiment) along the circumferential direction of the band portion 21, at 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)).

[0037] 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 in the left-right direction from the outer peripheral surface of the belt portion 21 and are arranged at multiple locations (three locations in this embodiment) along the circumferential direction of the outer peripheral 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 are in contact with the back surface of the fabric 2, continuing from the belt portion 21 (see Figures 5 to 7, and Figure 8(b)).

[0038] The connecting portion 22 is composed of a connecting piece 25 disposed at one end 21a of the band portion 21, and a connecting bracket 26 disposed at the other end 21a of the band portion 21 and with which the connecting piece 25 engages. The connecting piece 25 is formed by bending a plate-like body into a substantially U-shape, with a curved portion 25a protruding from the end 21a of the band portion 21 and a free end 25b not fixed to the band portion 21, and protruding from the outer circumferential surface of the band portion 21. The connecting bracket 26 is formed in a substantially rectangular parallelepiped shape and protrudes radially from the outer circumferential surface of the band portion 21, with a connecting hole 26a opened on the surface opposite the connecting piece 25, into which the curved portion 25a of the connecting piece 25 is inserted.

[0039] Since connecting portion 22 has flexibility in connecting piece 25, free end 25b can be deformed under stress load conditions in a direction that brings free end 25b closer to band portion 21. That is, when curved portion 25a of connecting piece 25 is inserted into connecting hole 26a of connecting bracket 26, connecting piece 25 is deformed in a direction that brings free end 25b closer to band portion 21, and the elastic force (restoring force) of connecting piece 25 presses free end 25b against connecting bracket 26 within connecting hole 26a, thereby engaging connecting piece 25 and connecting bracket 26 (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 apart (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 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 is easily deformed in a direction that reduces its diameter under stress load conditions, and in the connected state, a bending load acts on the band portion 21 and the band portion 21 is elastically compressed, generating an elastic force (restoring force) in a direction that expands both ends 21a.

[0041] Furthermore, 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 that reduces its diameter in the connected state compared to the open state, and therefore 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 blower device 1 of this embodiment is attached to the opening 3, the tubular portion 16 of the device main 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).

[0043] 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 Figs. 2 and 11). At this time, the attachment member 20 is pushed forward until the belt portion 21 and the auxiliary protrusions 24 abut against the back side of the fabric 2, and the belt portion 21 is positioned along the outer circumferential surface 16a of the tubular portion 16 of the device main body 10 (see Fig. 12).

[0044] Then, by operating mounting member 20, band portion 21 is deformed in a direction of reducing its diameter so that both ends 21a approach each other until they substantially abut, and while aligning it so that stepped recess 23 of band portion 21 corresponds to locking rib portion 18 of tubular portion 16, curved portion 25a of connecting piece 25 is inserted into connecting hole 26a of connecting bracket 26 to engage connecting piece 25 with connecting bracket 26. In this way, mounting member 20 is switched from the open state to a connected state in which both ends 21a of band portion 21 are connected by connecting portion 22, and by attaching band portion 21 of mounting member 20 by wrapping it around outer circumferential surface 16a of tubular portion 16, blower 1 can be attached to opening 3 (see FIG. 3).

[0045] 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 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 stepped recess 23 of the belt portion 21 abuts and engages with the locking rib portion 18, so the device main body 10 will not detach from the fabric 2 (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 (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 device 1 from the opening 3 of the fabric 2, the procedure is simply reversed from the above-mentioned attachment method. However, since the attached attachment 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 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) simply by pulling out the connecting piece 25 from the connecting hole 26a of the connecting bracket 26 and opening the connecting portion 22, and therefore the attachment 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 air blower 1 that houses a fan 12 therein and includes an air blower main body 10 that is provided with a flange 17 protruding from one end of a cylindrical tubular portion 16 that is inserted into the opening 3, and a locking rib 18 that protrudes radially from an outer circumferential surface 16a of the tubular portion 16 and is spaced apart from the flange 17, and an elongated body that is formed into a ring shape and is detachably attached to the tubular portion 16 of the air blower main body 10. The attachment member 20 comprises an end-opening annular belt portion 21 and a connecting portion 22 that connects the end 21a of the belt portion 21, and an attachment member 20 that is provided with the connecting portion 22 that connects the end 21a of the belt portion 21, and the attachment member 20 is attached so that the fabric is sandwiched between the flange portion 17 and the connecting portion 22 in a state where the belt portion 21 is arranged between the flange portion 17 and the engaging rib portion 18 along the outer peripheral surface 16a of the tubular portion 16 of the device main body 10.

[0049] In other words, the blower 1 of this embodiment is equipped with an attachment member 20 having an annular band portion 21 with an end and a connecting portion 22 that connects the ends 21a of the band portion 21.When the band portion 21 is 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 between them, and a connected state in which both ends 21a of the band portion 21 are connected closely together at the connecting portion 22 until they nearly abut.This allows the attachment of the band portion 21 of the attachment member 20 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.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, simply by 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 that can engage with the locking rib portion 18, so that the mounting member 20 can be positioned so that it cannot rotate relative to the device main body 10 when the blower device 1 is attached to the opening 3, and it is possible to prevent the connecting portion 22 from switching to an open state by itself or the connecting portion 22 from being damaged by rotation of the mounting member 20, etc.

[0052] Furthermore, 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 on 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.
