Description

The present invention relates to clothing worn by a wearer.

Conventionally, there is known clothing in which a detachable air blowing means for blowing outside air into the inside of the vest is attached, and in which an insertion hole through which a safety belt lanyard can be inserted is formed in the back of the garment (see, for example, Patent Documents 1 to 3). Such clothing has a structure that blocks the insertion hole in order to prevent air from leaking from the insertion hole when the safety belt lanyard is not inserted.

Patent No. 6545543 Patent No. 6191028 Patent No. 6793413

In conventional clothing, the structure for closing the insertion hole includes, for example, a linear fastener in the insertion hole, a pair of overlapping opening pieces attached above and below the insertion hole, and a closing piece that covers the insertion hole from the inside of the garment and has a pocket at the bottom end.

However, providing a line fastener causes problems such as the weight of the garment increasing and the cost increasing. Also, simply providing a closing piece with a pocket on the inside of the garment makes it difficult to adequately prevent air leaking from the insertion hole when the safety belt is not in use. This necessitates the need for a pair of opening pieces, which creates a problem of a complex structure and labor-intensive sewing.

The present invention was made with the above problem in mind, and aims to provide clothing that can prevent outside air sent in by a ventilation means from leaking through an insertion hole through which a lanyard is inserted, using a simple structure.

In order to achieve the above-mentioned object, the present invention is a garment in which a blowing means for blowing outside air into the inside of a vest is removably attached, the vest having an insertion hole formed therein through which a lanyard of a safety belt worn by the wearer can be inserted, a flap cloth extending downward from the insertion hole and covering the insertion hole from the outside of the vest , and an inner cloth provided inside the flap cloth and overlapping from the outside with the body part below the insertion hole, and configured to form a pocket space that is open upward between the flap cloth and the inner cloth.

As a result, the present invention can prevent outside air sent in by the air blowing means from leaking through the insertion hole through which the lanyard passes with a simple configuration.

The embodiment of the garment of the present invention will be described based on Example 1 shown in the drawings. In the following description, terms such as "up and down," "left and right," and "front and back" are used based on the wearer wearing the garment 10.

The garment 10 of Example 1 is a jacket (jumper) that can be worn by a wearer wearing a full harness type safety belt (not shown). Here, the "full harness type safety belt" has shoulder belts that are wrapped around each shoulder of the wearer, a waist belt that is wrapped around the waist, and thigh belts that are wrapped around each thigh, and each belt is connected to a lanyard at a position facing the wearer's back. The "lanyard" is the part of the safety belt that is connected detachably or integrally to the safety belt at one end and has a hook for connecting to a structure attached to the other end, which corresponds to a lifeline. The full harness type safety belt can distribute the impact load received by the wearer when falling over the entire body.

As shown in Figures 1 and 2, the garment 10 has a front part 20 that covers the front side of the wearer's torso (chest and abdomen), a back part 30 that covers the back side of the wearer's torso (back), a pair of sleeves 11, 11 that cover the wearer's arms, and a stand-up collar 12, with the front part 20 and back part 30 forming a vest.

In Example 1, the sleeves 11 are long sleeves that cover the entire arm of the wearer, but they may be short sleeves, three-quarter sleeves, five-quarter sleeves, etc., or a vest type without sleeves 11. Furthermore, the sleeves 11 may be detachable from the vest. The collar 12 may be folded back, or may not be provided. The garment 10 in Example 1 is made of fabric such as woven cloth or nonwoven fabric made of cotton or synthetic fibers. The fabric that forms the garment 10 may have any desired properties such as elasticity or flame retardancy, and the breathability can also be set as desired.

As shown in FIG. 1, the front part 20 is provided with a left front body 21 and a right front body 22 that are separated into left and right parts from the center in the width direction, a linear fastener 23 that freely opens and closes between the left front body 21 and the right front body 22, and the front parts of a pair of shoulder cloth parts 40, 41 that cover the left and right shoulders, respectively. In addition, the left front body 21 and the right front body 22 are each provided with a waist pocket 24 and a hook hanging part 25.

The waist pocket 24 is a pocket located at a position facing the waist (side) of the wearer. Here, the waist pocket 24 is formed by forming a cut in each of the left front body 21 and the right front body 22, and sewing the opening edge of a bag-shaped pocket bag (not shown) to the inside of the cut.

The hook attachment section 25 is for detachably hanging a hook attached to a lanyard connected to a full harness-type safety belt worn by the wearer of the garment 10. The hook attachment section 25 has a D-ring 25a to which the hook is attached, and a belt section 25b that attaches the D-ring 25a to the left front body section 21 or the right front body section 22. Here, the belt section 25b is folded in the middle while being inserted into the D-ring 25a, and the ends are sandwiched and sewn in the seams between the left front body section 21 or the right front body section 22 and the left and right shoulder cloth sections 40, 41, respectively.

In addition to the waist pocket 24, the front part 20 may have a chest pocket or other pockets at any position, or may not necessarily have a pocket. The front part 20 may also have a belt hole for pulling out a chest belt that connects to the shoulder belt of a safety belt, or a through hole for passing a radio cord or the like.

As shown in FIG. 2, the back section 30 includes a yoke 31 that covers the area from the neck to the shoulder blades of the wearer, the rear portions of the shoulder cloth sections 40, 41, and a back body section 32 that covers the center of the wearer's back and around the waist. Here, the back body section 32 is made up of multiple parts sewn together, and has sleeves 11 sewn on.

The rear body 32 is also formed with a pair of ventilation openings 33 to which a blower (blower means) (not shown) that blows outside air into the inside of the vest is detachably attached. The ventilation openings 33 are holes that penetrate the body fabric of the rear body 32, and the blower is inserted. The blower is fixed to the periphery of the ventilation openings 33. The rear body 32 may also be fitted with a reinforcing plate that strengthens the periphery of the ventilation openings 33, or with a closing cloth that can close the ventilation openings 33 as appropriate.

The top edge 31a of the yoke 31 is sewn to the collar 12, and the left and right side edges 31b are sewn to the shoulder cloth parts 40, 41, respectively. Also, here, gussets 31c are provided along each side edge 31b (see FIG. 6(a)). The gussets 31c are formed by pinching the yoke fabric on the front side of the garment 10 and sewing the edges of the folds.

Furthermore, as shown in FIG. 2, the lower end 31d of the yoke 31 overlaps the rear body 32 from the outside, but the lower edge of the yoke 31 is not sewn to the rear body 32. Therefore, an insertion hole 34 is formed between the yoke 31 and the rear body 32 in the back part 30 of the garment 10 (see FIG. 5). The insertion hole 34 is an opening through which the lanyard of a safety belt worn by the wearer can be inserted. The lower end 31d of the yoke 31 becomes a flap fabric that covers the insertion hole 34 from the outside of the vest.

As shown in FIG. 4, the edge 32a of the back body 32 that defines the insertion hole 34 has both sides 32b sewn to the yoke 31. This makes the width dimension W1 of the insertion hole 34 smaller than the width dimension W2 of the yoke 31. The edge 32a of the back body 32 is cut away from the position where it is sewn to the yoke 31 toward the bottom (hem) of the garment 10. The edge 32a of the back body 32 is reinforced by a facing cloth 32c.

Furthermore, as shown in Figs. 3 and 4, a breathable mesh cloth 35 is provided on the inside of the yoke 31, i.e., above the insertion hole 34. The mesh cloth 35 is a breathable fabric that is more breathable than at least the yoke 31 and the back body 32. Both side portions 35a of the mesh cloth 35 are sewn to the seam between the yoke 31 and the back body 32. In addition, the upper and lower ends 35b, 35c of the mesh cloth 35 are reinforced with piping.

As shown in FIG. 6(a), the lengthwise dimension L1 of the yoke 31 is largest in the center in the widthwise direction and gradually becomes smaller toward the left and right side edges 31b (sides in the widthwise direction). Therefore, the lower end 31d of the yoke 31 has a wedge shape that is pointed downward. This ensures that the yoke 31 has an area that covers the insertion hole 34, while preventing the lanyard inserted into the insertion hole 34 from getting caught on the yoke 31 when it is pulled left or right.

The inner cloth 36 shown in FIG. 6(b) is provided on the inside of the lower end 31d of the yoke 31, facing the insertion hole 34. Both side edges 36b and the lower edge 36c of the inner cloth 36 are sewn along the periphery of the yoke 31. As a result, a pocket space P that is open upward is formed between the yoke 31 and the inner cloth 36 (see FIGS. 7 and 8). In other words, by sewing the inner cloth 36 to the inside of the yoke 31, a pocket space P that faces the insertion hole 34 is provided on the inside of the yoke 31.

Here, the pocket space P is defined by an opening 37 defined by the upper edge 36a of the inner cloth 36. Both side portions 36d of the upper edge 36a of the inner cloth 36 are sewn to the yoke 31, and the width dimension of the opening 37 is approximately the same as the width dimension of the insertion hole 34. The upper edge 36a of the inner cloth 36 is located slightly below the lower end 35c of the mesh cloth 35.

In addition, here, the lower end 31d of the yoke 31 has a wedge shape that is pointed downward, and the lower edge 36c of the inner cloth 36 sewn along the periphery of the yoke 31 also has a wedge shape that is pointed downward. Therefore, the lower edge of the pocket space P has a wedge shape that is pointed downward, just like the yoke 31, and the width direction gradually narrows downward.

The inner cloth 36 is made of the same fabric material as the yoke 31, but has a higher rigidity than the yoke 31, for example, by attaching an adhesive interlining. The inner cloth 36 is also larger in size than the lower end 31d of the yoke 31, and has some slack relative to the lower end 31d of the yoke 31.

And because the edge 32a of the back body 32 is cut out toward the bottom of the garment 10, the upper edge 36a of the inner cloth 36 is located above the center of the edge 32a of the back body 32 (toward the collar 12), as shown in FIG. 4. As a result, the opening 37 of the pocket space P is located above the insertion hole 34.

The function of the garment 10 of Example 1 will be explained below with reference to Figures 9 and 10.

When the wearer wears the garment 10 of the first embodiment while wearing a full harness type safety belt (hereinafter simply referred to as a "safety belt"), the lanyard extending from the safety belt is passed through the insertion hole 34. The insertion hole 34 is less likely to have a large gap when the lanyard is passed through, and when outside air is blown into the garment 10 (vest) from a blower attached to the ventilation opening 33, outside air does not leak unnecessarily through the insertion hole 34. Therefore, if the line fastener 23 is pulled up, the left front body 21 and the right front body 22 are connected, and the front part 20 is closed, the garment 10 is almost sealed. This allows outside air to flow appropriately between the garment 10 and the wearer, drying the wearer's sweat and lowering body temperature.

In contrast, when the wearer puts on the garment 10 without wearing a safety belt, there is no need to pass the lanyard through the insertion hole 34. In this case, a gap is created in the back portion 30 by the insertion hole 34.

In this way, when the lanyard is not passed through the insertion hole 34, the front part 20 is closed and the blower attached to the ventilation opening 33 is driven to send outside air into the garment 10. As shown in FIG. 9, the outside air (indicated by arrow G in FIG. 9 and FIG. 10) first flows between the rear body 32 and the wearer X. As a result, the rear body 32 expands due to the outside air G, and bulges in a direction away from the wearer X.

After that, the outside air G flows along the yoke 31, and some of the outside air G heads toward the collar of the wearer X. At this time, mesh cloth 35 is provided in a position opposite the yoke 31. This allows the mesh cloth 35 to create a gap (air passage) between the yoke 31 and the wearer X, making it easier for the outside air G to pass through. In addition, gussets 31c are provided along the left and right side edges 31b of the yoke 31. This makes it easier for the yoke 31 to expand, increasing the gap between the yoke 31 and the wearer X, allowing more outside air G to flow toward the collar of the wearer X.

As shown in Figures 9 and 10, a portion of the outside air G that flows along the yoke 31 does not flow toward the collar of the wearer X, but flows toward the bottom of the garment 10. Here, an inner cloth 36 is provided on the inside of the lower end 31d of the yoke 31, forming a pocket space P. Therefore, the outside air that flows toward the bottom of the garment 10 along the yoke 31 flows into the pocket space P, inflating it. This causes the inner cloth 36 to bulge in a direction approaching the wearer X.

That is, as shown in FIG. 9, the outside air G that flows between the wearer X and the rear body 32 and the outside air G that flows into the pocket space P causes the rear body 32 and the inner cloth 36 to expand so that they come into contact with each other, and the gap created by the insertion hole 34 is closed. As a result, even if the lanyard is not passed through the insertion hole 34, leakage of outside air G from the insertion hole 34 can be suppressed. The garment 10 can then be made almost airtight.

The insertion hole 34 is simply covered from the outside of the back body 32 by the yoke 31, and there is no need for, for example, a pair of overlapping opening pieces attached around the insertion hole 34. In addition, the inner cloth 36 has both side edges 36b and the bottom edge 36c sewn to the inside of the yoke 31, making it easy to install the inner cloth 36.

In this way, the garment 10 of Example 1 can, with a simple configuration, prevent the outside air G taken in by the blower from leaking through the insertion hole 34 through which the lanyard is inserted.

In addition, in the garment 10 of Example 1, the edge 32a of the back body 32 is cut away toward the bottom of the garment 10, so that the opening 37 of the pocket space P is located above the insertion hole 34. Therefore, the lanyard inserted into the insertion hole 34 will not be inserted into the pocket space P, and the lanyard can be easily inserted.

In addition, in the garment 10 of Example 1, the rigidity of the inner cloth 36 is made higher than that of the yoke 31 by, for example, attaching an adhesive interlining to the inner cloth 36. This makes it difficult for the opening 37 of the pocket space P defined by the upper edge 36a of the inner cloth 36 to deform, and prevents the upper edge 36a of the inner cloth 36 from rolling up due to the flow of outside air G, etc., and narrowing the opening 37. This makes it easier for outside air G to be taken into the pocket space P, and allows the inner cloth 36 to inflate sufficiently. Also, by not increasing the rigidity of the yoke 31, the yoke 31 is more likely to inflate due to outside air G, making it easier for outside air G to flow into the pocket space P.

In addition, in the garment 10 of Example 1, the inner cloth 36 is larger in size than the lower end 31d of the yoke 31, and the inner cloth 36 has slack relative to the lower end 31d of the yoke 31. This makes it easier for the pocket space P to expand, making it easier for outside air G to be taken into the pocket space P.

In addition, the pocket space P has a downwardly pointed wedge shape, with the body width gradually narrowing toward the bottom. This makes it easy to introduce outside air G into the pocket space P, allowing the pocket space P to be sufficiently expanded.

The garment 10 of the present invention has been described above based on Example 1, but the specific configuration is not limited to these examples, and design changes and additions are permitted as long as they do not deviate from the gist of the invention as defined by each claim in the scope of the claims.

In the garment 10 of the first embodiment, the rigidity of the inner cloth 36 is made higher than that of the yoke 31 to improve the retention performance of the opening 37 of the pocket space P, but this is not limited to the above. For example, a reinforcing member extending in the width direction may be attached to the upper edge 36a of the inner cloth 36. The reinforcing member is made of a wire formed of a soft metal or soft synthetic resin that has shape retention performance, and is freely deformable. By attaching such a reinforcing member to the upper edge 36a of the inner cloth 36, the opening 37 of the pocket space P can be maintained in any shape, making it easier to take in outside air G into the pocket space P. For example, the reinforcing member can be attached to the inner cloth 36 by folding back the upper edge 36a of the inner cloth 36 and sandwiching the reinforcing member inside the fold.

In addition, in the garment 10 of Example 1, an example is shown in which the upper edge 36a of the inner cloth 36 is located slightly lower than the lower end 35c of the mesh cloth 35. However, this is not limited to this, and for example, the lower end 35c of the mesh cloth 35 and the upper edge 36a of the inner cloth 36 may be sewn together, and the opening 37 of the pocket space P may be closed by the mesh cloth 35, which is a breathable fabric.

By blocking the opening 37 of the pocket space P with the mesh cloth 35, it is possible to ensure that outside air can be taken into the pocket space P, while preventing the lanyard from being mistakenly inserted into the pocket space P when passing it through the insertion hole 34.

The upper edge 36a of the inner cloth 36 may be positioned higher (closer to the collar 12) than the lower end 35c of the mesh cloth 35, or the upper edge 36a of the inner cloth 36 and the lower end 35c of the mesh cloth 35 may be positioned at the same position. Even in these cases, the mesh cloth 35 can prevent the lanyard from being inserted into the pocket space P.

In addition, in Example 1, a gap is created between the yoke 31 and the rear body 32 to form the insertion hole 34, and the lower end 31d of the yoke 31 is used as a flap cloth to cover the insertion hole 34. However, this is not limited to this. For example, the back part 30 may be composed of only the rear body 32, a cut may be formed in the rear body 32 to form the insertion hole 34, and a flap cloth with a pocket space P formed above the cut may be fixed to cover the insertion hole 34. In other words, the flap cloth may be composed of a separate member from the back part 30.

In addition, in the garment 10 of Example 1, the lower end 31d of the yoke 31, which is the flap fabric, is shown as being wedge-shaped and pointed downward, but this is not limited to this. For example, the yoke may be a round type with an arc-shaped lower edge, or a box type with a square lower edge. The pocket space P may also have a curved or square lower edge. In other words, the shapes of the flap fabric and the pocket space P can be set as desired.
