Description

Technical Field

[0006] , ,

[0007] ,

[0001] The present invention relates to a tool for introducing cooling air from a jacket with a blower fan for air conditioning to trousers, and trousers provided with such a cooling air introduction tool.

Background Art

[0002] In generally widely spread air-conditioned clothes, the blower fan is attached to and used on the jacket and not attached to the trousers, so the lower body cannot be cooled.

[0003] In this regard, Patent Document 1 discloses trousers (1) provided with a holding part (16) / accommodating part (17) of a spacer (9) that is inserted inside a jacket (2) with a blower fan (3) and secures an air circulation path communicating with the space inside the jacket (2) on the inner surface side.

[0004] This is considered to be the prior art closest to the present invention in that it forms an air circulation path from the jacket (2) to the trousers (1). ​​​​​​​​​​​​​​​​​​​​​​​​​Furthermore, a rectangular mesh spacer holder (16), as viewed from the front, is attached (sewn) to the waistband (13) and back panel (12) of the trousers (1), and a storage pocket (17) for the spacer (9) is installed in the holder (16).

[0008] Moreover, the spacer storage pocket (17) is a long, bottomed cylindrical shape in the vertical direction, and long cylindrical or semi-cylindrical spacers (9) that are also oriented vertically can be inserted into and removed from its interior. Furthermore, each of these spacers (9) is independently installed in a parallel configuration.

[0009] Therefore, even if the spacer (9) is made of a cushioning material, it will restrict or cause discomfort to the wearer's movements such as bending at the waist (working posture), and since the individual arc surfaces of the spacer (9) are in contact with the wearer's body and not in overall surface contact, it will not be able to efficiently and quickly cool the wearer's lower body.

[0010] Moreover, the number of parts required to secure an air passage from the jacket (2) to the trousers (1) is extremely large, and the assembly structure from these parts is complex and specialized. As a result, there are problems in that manufacturing costs cannot be reduced, ease of use cannot be achieved, and the versatility of the trousers (1) cannot be obtained. [Means for solving the problem]

[0011] This invention aims to improve upon such problems, and in order to achieve this objective, claim 1 describes a cooling air introduction device that is inserted and used to introduce cooling air from an air-conditioning fan-equipped jacket into the inside of trousers,

[0012] It comprises a pair of left and right ventilation members, each consisting of a flat, disc-shaped cushion pad of a certain thickness packed inside a cushion mesh bag, and a flexible, non-breathable base fabric common to both ventilation members.

[0013] The pouches of both ventilation members are joined and integrated onto the front of the base fabric in a nearly symmetrical parallel state, maintaining a certain gap for folding,

[0014] A key feature is that a pair of attachment bands, each having a detachable fastener for attaching to trousers, are integrally suspended from the back of the base fabric.

[0015] Furthermore, in claim 2, the upper ends of both attachment bands, which are joined and integrated to the back surface of the base fabric, are both positioned at a height on a virtual horizontal line that crosses the central part of both ventilation members,

[0016] When inserted and installed inside the trousers, the upper ends of both mounting bands are secured to the upper edge of the trouser opening from above, and the ventilation members and their mounting bands are positioned to sandwich the trousers from the front and back.

[0017] Furthermore, in claim 3, when the upper ends of both attachment bands, which are joined and integrated to the back of the base fabric, are inserted into the inside of the trousers and installed, they are positioned at a height that allows them to lock onto the upper edge of the opening of the trousers from above.

[0018] The lower half of both ventilation members is recessed into the inside of the trousers to a depth equal to or greater than that of the lower half, while the remaining upper half is set to protrude from the trousers toward the jacket to a height equal to or less than that of the upper half.

[0019] Furthermore, claim 4 is characterized in that the entire structure of the base fabric and the two ventilation members, to which the wrapping bag is joined and integrated on the front, is shaped to be approximately semicircular, isosceles trapezoidal, rectangular, or other symmetrical contour shapes when viewed from the front.

[0020] Furthermore, in claim 5, the upper ends of both mounting bands are sewn to the back of the base fabric,

[0021] The lower ends of both attachment bands are each fitted with snap buttons and / or hook-and-loop fasteners, respectively, which serve as fasteners that can be attached to and detached from trousers.

[0022] In addition, in claim 6, a pair of left and right handles for extracting both ventilation members inserted and installed inside the trousers are integrally projected upward from the back surface of the base fabric.

[0023] In addition, in claim 7, a locking tool that can be engaged and disengaged with the locking tool on the side of the cooling air introduction tool described in claim 1 is provided on the buttocks that are a certain distance below the waistband.

[0024] The cooling air introduction tool described in claim 1 is in a state of being inserted and installed inward by the engagement of the locking tools with each other.

Effect of the Invention

[0025] According to the configuration of the cooling air introduction tool described in claim 1, by inserting and installing it inside the trousers worn together with a jacket with a blowing fan for air conditioning, the air (for cooling) sucked by the blowing fan can be efficiently introduced from the inside of the jacket to the inside of the trousers automatically, and the lower body of the wearer can be quickly cooled.

[0026] In that case, the pair of left and right ventilation members are composed of a cushion mesh bag (a cushion cover made of mesh fabric) and a cushion pad packed in a flat plate shape with a certain thickness inside. Since the bags of both ventilation members are joined and integrated in a substantially symmetric parallel state with a certain gap for folding to the front surface (inner surface / body side of the wearer) of the base fabric without air permeability, it fits well around the waist (torso) of the wearer and forms a smooth cooling air flow path (spacer) from the inside of the jacket to the inside of the trousers automatically, and there is no risk of leakage of cooling air to the outside from the flow path.

[0027] In addition, since the trousers worn together with the above-mentioned jacket with a blowing fan also adopt the configuration of claim 7, the above-mentioned cooling air introduction tool can be quickly and easily attached or removed to the buttocks of the wearer, and it is also possible to provide general trousers that are not worn together with the jacket with a blowing fan, which has excellent mass productivity and versatility.

[Figure 9] This is a schematic enlarged cross-sectional view along line 9-9 in Figure 8. [Figure 10] This is a schematic enlarged cross-sectional view along the line 10-10 in Figure 9. [Figure 11] This is a rear view showing the garment being worn, consisting of a jacket and trousers. [Figure 12] This is a side view of Figure 11. [Modes for carrying out the invention]

[0029] Preferred embodiments of the present invention will be described in detail below based on the drawings. Figure 1 shows a jacket (A) and trousers (B) of an air-conditioned garment, with a pair of left and right blower fans (10) installed in parallel on the back of the jacket (A). In the illustrated example, both blower fans (10) are mounted at a relatively high position near the armpits on the sleeveless jacket (A), but the number and mounting position of the fans (10) can be appropriately selected, and the jacket (A) may have long sleeves or short sleeves. Note that the rotary drive motor of the blower fans (10), the battery that powers it, and the electrical wiring connecting them are not shown.

[0030] In any case, the jacket (A) is made of non-breathable polyester, nylon, or other flexible synthetic fibers, and an elastic material such as a rubber cord is attached to its hem (11). By making this part tightly fitted around the wearer's waist (torso), the cooling fan (10) draws air (cooling air) into the inside of the jacket (A), preventing it from leaking out from other parts except the collar and sleeves.

[0031] On the other hand, the trousers (B) are made of the same synthetic fibers as the top (A), and their waistband (12) is tightened around the wearer's waist (torso) by an elastic material such as a rubber band sewn into it, or by a separate non-elastic cord or belt. The example shows long trousers in the style of slacks, but they can also be shorts.

[0032] In any case, at a certain distance (Y) below the waistband (12) of the trousers (B), a fastener (14) for attaching a cooling air introduction device (C) from the upper garment (A) to the trousers (B), which will be described later, is preferably installed in parallel as a pair on the left and right, corresponding to the above-mentioned air blower (10). In the illustrated example, a female snap button is shown as the fastener (14), but a female hook-and-loop fastener may be used instead, and furthermore, the button and hook-and-loop fastener may be attached in a pair, one on top and one on the bottom, so that they can be used together.

[0033] The cooling air introduction device (C) for the trousers (B) functions as a flow channel (spacer) that distributes and introduces air (cooling air) drawn in from the jacket (A) to the inside of the trousers (B) by the fan (10) of the jacket (A). It comprises a pair of left and right ventilation members (15) in which cushion pads (15b) are packed into a flat plate of a certain thickness (T) inside a cushion mesh bag (mesh fabric cushion cover) (15a) as shown in detail in Figures 2-6, and a flexible, non-breathable base fabric (16) common to the pair of ventilation members (15). The pair of bag (15a) in which the cushion pads (15b) are packed into the ventilation members (15) are joined and integrated in a nearly symmetrical parallel state that maintains a certain gap (W) for folding toward the front (inner surface / wearer's body side) of the base fabric (16).

[0034] Furthermore, the entire cooling air introduction device (C), which consists of the two ventilation members (15) arranged in a symmetrical parallel configuration, is shaped like a symmetrical hexagonal outline, with the lower corners at both ends of a horizontally elongated rectangle (for example, long side: approximately 355 mm x short side: approximately 210 mm) as seen from the front in Figures 2 and 6, cut at an angle of approximately 45 degrees.

[0035] In this case, the cushion pad (15b) of the ventilation member (15) is made of polyethylene cushioning material, and when it is surrounded by a cushion mesh bag (mesh fabric cushion cover) (15a), the constant thickness (T) in the flat state is, for example, about 35 mm, and the mutual gap (W) between adjacent ventilation members (15) is also dimensioned to, for example, the same about 35 mm, so that it can be folded in half and made smaller along a so-called symmetrical virtual vertical center line (OO).

[0036] Furthermore, it is preferable to sew colored piping tape (17) to the periphery of each individual breathable member (15), which consists of the cushion pad (15b) and the surrounding bag (cushion cover) (15a). In the illustrated embodiment, sewing is used as the means of joining the bag (cushion cover) (15a) to the base fabric (16), but welding, adhesive, or other means may be used instead.

[0037] (18) is an attachment band for the cooling air introduction device (C) to the trousers (B), which is in the form of a tape of a certain width (e.g., about 30 mm) and length (e.g., about 95 mm), and preferably a pair of left and right upper ends that correspond to the fastener (14) on the trousers (B) side are at a height position aligned on a virtual horizontal line (LL) that crosses the central part of both ventilation members (15) as shown in Figure 6, and are both joined and integrated to the back (outer surface) of the base fabric (16) by sewing or other means.

[0038] Furthermore, at the lower ends of the two attachment bands (18) that hang down from the back of the base fabric (16), there are attached fasteners (19) that can be attached to and detached from the fastener (14) on the trousers (B). The fastener (19) on the cooling air intake device (C) side has a male-female (concave and convex) relationship with the fastener (14) on the trousers (B) side, and therefore, although the example shows a male snap button as the fastener (19), this can also be replaced with a male hook-and-loop fastener, and the button and hook-and-loop fastener can also be used together as an upper and lower pair.

[0039] In the illustrated embodiment, since the upper ends of both mounting bands (18) are sewn onto a virtual horizontal line (LL) that crosses the center of both ventilation members (15) on the back of the base fabric (16), when the ventilation members (15) of the cooling air introduction device (C) are inserted into the inside of the trousers (B) from above, and the fasteners (19) attached to both mounting bands (18) are detachably fastened to the fasteners (14) attached to the buttocks (13) of the trousers (B), as shown in Figures 7 to 10, the upper ends of both mounting bands (18) are fastened so that they straddle the upper edge of the opening of the waistband (12) of the trousers (B), and the ventilation members (15) and their mounting bands (18) sandwich the trousers (B) from the front back (inside and outside) direction.

[0040] Moreover, as suggested by Figures 11 and 12, the lower half of both ventilation members (15) is embedded in the inside of the trousers (B) by a depth (D) equal to or greater than that of the lower half, while the remaining upper half is extended outwards from the trousers (B) toward the inside of the jacket (A) by a height (H) equal to or less than that of the upper half. Furthermore, both ventilation members (15) can be bent through their adjacent gaps (W) and conform well to the wearer's waist (torso) and fit snugly to the entire surface.

[0041] As a result, the insertion and installation of the cooling air introduction device (C) into the trousers (B) is maintained in a remarkably stable state. Furthermore, the fact that the aforementioned gap (W) serves as a passage for the cooling air, combined with the fact that the base fabric (16) of both ventilation members (15) is not breathable, allows for rapid and efficient cooling of the wearer's lower body.

[0042] Furthermore, (20) is a pull tab used to pull out the ventilation member (15) of the cooling air introduction device (C), which is inserted and installed inside the trousers (B), and preferably a pair of loop-shaped detachable ends, as shown in the figure, are sewn to the upper corners of both ends of the back (outer surface) of the base fabric (16).

[0043] Since both pull tabs (20) extend upward integrally from the base fabric (16), the two ventilation members (15) can be easily and quickly removed from the inside of the trousers (B) by grasping them and pulling upward, and the cooling air introduction device (C) can be conveniently washed and dried by hanging the pull tabs (20).

[0044] Since the cooling air introduction device (C) of the illustrated embodiment has the above configuration, by inserting the cooling air introduction device (C) into the inside of the trousers (B) worn together with the air-conditioned jacket (A) equipped with a fan (10), as shown in Figures 11 and 12, the air (cooling air) drawn in by the fan (10) into the inside of the jacket (A) can be introduced into the inside of the trousers (B) in such a way that it can be distributed, thereby efficiently cooling the lower body of the wearer.

[0045] Specifically, around the time the trousers (B) are put on, the ventilation member (15) of the cooling air introduction device (C) is inserted into the inside of the trousers (B), and its pair of attachment bands (18) are secured so as to straddle the upper edge of the opening of the waistband (12), and the fasteners (male snap buttons in the illustrated example) (19) attached to the lower ends of both attachment bands (18) are fastened to the fasteners (female snap buttons in the illustrated example) (14) installed on the buttocks (13) of the trousers (B).

[0046] In this way, the ventilation member (15) of a certain thickness (T) in the cooling air introduction device (C) and its pair of attachment bands (18) on the left and right sides will be sandwiched between the trousers (B) from the front and back (inside and outside) directions, and the lower half of the ventilation member (15) will be recessed inward from the waistband (12) of the trousers (B) by a depth (D) equal to or greater than that of the lower half of the ventilation member (15), while the remaining upper half will be extended inward toward the top garment (A) by a height (H) equal to or less than that of the upper half, thereby securing a cooling airflow passage (spacer) along the vertical direction.

[0047] In this case, the ventilation member (15) consists of a flat cushion pad (15b) of a certain thickness (T), and as shown in Figures 9 and 10, it is in close contact with the waist (torso) of the trousers (B) being worn, and cooling air flows through itself and the adjacent gaps (W) between the two ventilation members (15). On the back side (outer surface / opposite side from the body) of the ventilation member (15) there is a non-breathable base fabric (16) which acts as a barrier to prevent the cooling air from leaking out.

[0048] As a result, the air (cooling air) drawn in by the blower fan (10) can be introduced efficiently and without leakage from the inside of the jacket (A) to the inside of the trousers (B), resulting in a remarkably superior cooling effect inside the trousers (B). The configuration required to achieve this effect requires only the minimum number of parts and can be easily manufactured.

[0049] Furthermore, even when used as trousers (B) to which the above-mentioned cooling air introduction device (C) is inserted and installed, it is sufficient to simply install the detachable fastener (14) attached to the mounting band (18) on the cooling air introduction device (C) side at the position of the buttocks (13) at a certain distance (Y) below the waistband (12) of the trousers (B), as shown in Figure 1. Since this does not require a complex or special specification, it can be provided without any problems as general trousers (B) that are not worn together with the jacket (A) equipped with a cooling fan (10).
