Description

Upper garment

This invention relates to an upper garment that has a gusset under the armpit and has good follow-up ability even when the arm moves vigorously.

For upper clothes such as uniforms and underwear that are worn in volleyball and baseball sports, especially in sports where arms are raised and lowered vigorously, a gusset has been conventionally placed under the armpits in order to improve the ability to follow intense arm movements. Has been done.

Gusset increases the fit by making the upper garment thicker. FIG. 14 shows the base portion of the sleeve, the body line 10 is shown by a one-dot chain line, the upper clothing line 11 is shown by a solid line, and the upper clothing line 12 is shown by a dashed line when no gusset is attached. ing. As shown in FIG. 14, when the gusset is arranged in the armpit portion of the upper garment, the sickle bottom a (the most recessed portion of the armpit) of the upper garment can be raised and the sleeve length b (the range of the arrow) can be increased. Therefore, it is possible to improve the fit, it is easy to raise the arm smoothly.

By the way, as a conventional gusset shape, as shown in FIG. 15, the straight gusset 13 having a substantially constant width is arranged in a region extending from the hem through the armpit to the cuff, and is disposed in the same region. There are a spindle gusset 14 (Patent Document 1) shown in FIG. 5 and a rhombus gusset 15 arranged near the armpit as shown in FIG.

However, the conventional gusset has the following problems.

First, when attaching the gusset to the front body, back body and upper sleeve, as shown in FIG. 14, when the sickle bottom a is raised, the armpit part of the upper garment can be fitted to the body 10, and the lower sleeve Since the dimension b becomes longer, it is easy to raise the arm. However, if the bottom of the sickle a is raised too much, there is not enough room around the shoulder when the arm is lowered. Become.

The tendency becomes remarkable in the straight gusset 13 as shown in FIG.

In FIG. 14, the direction of the tightening force at the upper shoulder is indicated by an arrow c.

In the armpit, the spindle gusset 14 and the diamond-shaped gusset 15 with widened gussets allow the fabric to be removed under the armpits, so that the tightening force on the armpits is relaxed. However, there is no room for the upper shoulder, and the tightening force on the upper shoulder cannot be relaxed.

Next, when the arm is raised, a region d having a large skin stretch in the vertical direction is formed in the body side part of the body. Therefore, as shown in FIG. When approaching parallel to the line e, the stitch f hinders the stretch of the skin, and the upper garment is pulled.

This pulling is particularly problematic in the straight gusset 13 where the stitch f runs along the body side.

As described above, the conventional gusset has a problem that tightening around the shoulder is large and pulling by the stitch f is large.

Therefore, the present invention intends to provide an upper garment having a gusseted structure in which tightening around the shoulder and pulling by stitches are less likely to occur even if the sickle is raised and the arms are easily raised.

The upper garment according to the present invention is obtained by integrally suturing a front body, a back body, a sleeve, and an elongated piece of gusset extending from the armpits of the front body and the back body in the armpit and cuff directions, The gusset is composed of three blocks, a side part, a side part, and a sleeve part. The side part and the sleeve part of the gusset have both side edges formed by gentle curves or straight lines. The front part that has a front convex part and a rear convex part that are gradually curved and spreads most near the bottom of the sickle at both side edges of the front side lower part and the rear side lower part, and the front convex part and the rear convex part of this gusset are stitched together The shape of the back body and the sleeve part is characterized by having an irregular shape that does not have a dent that fits the front convex part and the rear convex part of the gusset.

Further, the upper garment according to the present invention is characterized in that the material of the gusset is a material that has a higher elastic force in the width direction than the material of the body and is difficult to bend.

Further, the upper garment according to the present invention is characterized in that the length of the gusset is longer than the length from the waist line through the armpit to the elbow line.

Further, the upper garment according to the present invention is characterized in that the length of the gusset is shorter than the length from the waist line to the elbow line through the armpit.

Further, the upper garment according to the present invention is characterized in that the gusset extends from the vicinity of the waist line to the vicinity of the elbow line through the armpit.

As described above, the present invention forms the front convex portion and the rear convex portion which are gradually curved and spread most in the vicinity of the sickle bottom on both side edges of the front side lower part and the rear side lower part of the gusset. The body part and the rear convex part act as a loose amount, and further, the shape on the body side where the front convex part and the rear convex part are stitched does not have a dent that fits the front convex part and the rear convex part of the gusset By forming it in a different shape, a force that pushes up from the gusset to the body acts, the tightening force of the upper shoulder decreases, and the gusset and the body are less likely to be pulled by stitching.

FIG. 1 is a schematic view of the upper garment 1 according to the present invention, shown in a state before the left gusset 2 is sewn.

The gusset 2 according to the present invention is composed of three blocks: a side part A, a side part B, and a sleeve part C.
The armpit B is a region d where the body's skin stretches greatly during an arm raising operation, and the front convex portion that gradually curves and spreads most near the sickle bottom 13 on both sides of the front armpit and the back armpit of the region d. 3 and the rear convex part 4 are formed. A chain line denoted by reference numeral 5 indicates a shape line of the armpit portion of the conventional straight gusset 13.
Both sides of the side part A and the sleeve part C are formed in a straight line or a strip shape having a substantially constant curvature.

As described above, the armpit B is a region d where the body's skin stretches greatly during the arm raising operation, and the border with the armpit A is the rectus abdominis muscle as shown in FIG. 2A. It is located in the chest cross section passing through the point adhering to the anterior lobe H at the top of the sheath, and the boundary with the sleeve C is located in the upper arm cross section passing through the point where the deltoid muscle I attaches to the deltoid rough surface J of the humerus.

As shown in FIG. 2B, the position of the protruding part of the armpit B, that is, the position of the apex of the front convex part 3 and the rear convex part 4, is the vicinity of the front saddle point K, that is, around the arm root. As shown in FIG. 2C, the front position is at the upper edge of the wrinkle between the trunk and the arm, and the rear position is in the vicinity of the rear saddle point L, that is, the rear surface around the root of the arm. At the top edge of the wrinkle at the border.

The width of the armpit B, that is, the width of the front and back projections 3 and 4 is 10-14% of the chest circumference at the border of the armpit A, and the apex of the front and back projections 3 and 4 At the position, 14 to 22% of the chest circumference and the boundary portion of the sleeve C are set in the range of 9 to 13% of the chest circumference, respectively.

FIG. 3 shows a left front body D, an upper sleeve E, and a left rear body F that constitute a body for sewing the left gusset 2 according to the present invention.

As shown in FIG. 3, the shape line of the armpit side armpit that sews the front convex part 3 and the rear convex part 4 of the armpit 2 of the gusset 2 according to the present invention is the front convex part 3 and the rear convex part. 4, that is, a curve having a substantially constant curvature without providing a recess 6 corresponding to the front convex part 3 and the rear convex part 4 of the gusset 2.

In the gusset 2 according to the present invention, as described above, the front convex part 3 and the rear convex part 4 in which the sides of the body are gradually curved and the sickle bottom a is most widened in the region d where the body's skin stretches greatly during arm raising operation. The shape line of the armpit side under which the front convex part 3 and the rear convex part 4 of the gusset 2 are sewn is formed into an irregular shape without the recess 6 that fits the front convex part 3 and the rear convex part 4 Is formed. As a result, a force of pushing up the gusset 2 from the gusset 2 acts, the tightening force of the upper shoulder is reduced, and it is difficult for the stitch 8 to sew the gusset 2 and the garment to be pulled. In FIG. 1, the pushing force acting on the body from the gusset 2 is schematically indicated by an arrow 7.

Experiments were carried out on how the push-up force from the gusset to the body, the tightening force of the upper shoulder, and the pulling by the stitches 8 that sew the gusset and the body change due to the difference in gusset shape. The gusset 2 has a higher push-up force on the body than the gusset structures of Comparative Examples 1 to 4 below, and has a higher effect of reducing the tightening force of the upper shoulder, and stitches 8 that sew the gusset and the body together. As a result, it was found that the clothes pull-in phenomenon caused by

Comparative Example 1 in which a comparative experiment was performed uses a straight gusset 13 having a shape shown in FIG. 4 that does not have a protruding part at the side lower part, and the front convex part 2 and the rear convex part from the gusset 2 of the present invention. 3 is excluded.

Comparative Example 2 in which a comparative experiment was performed is a spindle gusset 14 having a shape shown in FIG. The width L of the widest bottom part a of the gusset 14 of this comparative example 2 is the same as the width of the bottom part a of the front convex part 2 and the rear convex part 3 of the present invention.

Comparative Example 3 in which a comparative experiment was performed is a spindle gusset 16 having a shape that gradually expands toward the side of the armpit. As shown in FIG. 6, the width L of the sickle bottom a of the armpit is lower than that of Comparative Example 2. The area S ₁ , S ₂ of the portion that spreads outward on the basis of the shape line 5 of the straight gusset 13 that is narrow and does not have the front convex part 2 and the rear convex part 3 at the side lower part is defined as the front convex part of the gusset of the present invention. This is the same as the areas S ₁ and S _{2 of the} part 2 and the rear convex part 3.

In Comparative Example 4 in which a comparative experiment was performed, the gusset shape was the same as that of the gusset 2 according to the present invention. However, as shown in FIG. 7, the front convex portion 2 and the rear convex portion 3 of the gusset are stitched together. The front body, the upper sleeve, and the shape line of the back armpit are formed with a recess 6 that fits the front convex portion 2 and the rear convex portion 3. An alternate long and short dash line 9 in FIG. 7 indicates the shape line of the armpit of the body of the present invention.

In the comparative examples 1 to 3, the front body D, the upper sleeve E, and the back armpit F are sewn on the front side line and the rear side line of the gusset. It is in shape.

First, when the pressure applied to the upper arm portion was changed by applying a pressure sensor to the upper arm portion in relation to the arm raising angle when each upper garment was worn, the graph in FIG. 8 was measured. As shown in FIG. 4, the embodiment of the present invention is less than half the clamping pressure when the arm raising angle is 0 degree, 45 degree, 90 degree, or 180 degree as compared with the comparative example 1 of the straight gusset 13. It was possible to reduce. Moreover, when compared with Comparative Example 2 of the wide spindle gusset 14, the reduction effect was almost the same at 0 degrees and 45 degrees, but there is a large difference in the reduction effect when the arm raising angle is 90 degrees or more. occured.

Further, the gusset shape is the same as that of the present invention, but Comparative Example 4 in which a dent 6 that fits the front convex portion 2 and the rear convex portion 3 is provided on the body side is a dent 6 in the armpit portion of the body. The armhole became smaller by the amount attached, and the clearance at the top of the shoulder decreased, especially the tightening pressure when the arm raising angle was 90 degrees or less was greatly increased.

Next, when the arm raising angle is 180 degrees, a marker is attached along the stitch line f to show how the stitches (seam) between the gusset and the body affect the body skin stretch. The relative position from the position of was confirmed. As a result, as shown in the graph of FIG. 9, in the embodiment of the present invention, the angle between the curved line of the stitch line f and the skin elongation line e indicated by the vertical axis of the graph is larger than any of the comparative examples. It was confirmed that the skin elongation was not inhibited.

In the embodiment of the present invention, as shown in FIG. 10, the stitch line f is greatly curved in the region d where the skin stretch is large, and the angle θ formed by the stitch line f and the skin stretch line e is large. Does not inhibit the skin stretch, and as a result, during the arm raising operation, it is possible to alleviate the pulling and reduce the displacement. On the other hand, in the straight gusset 13, as shown in FIG. 15, the angle θ formed by the stitch line f and the skin stretch line e is small in the region d where the skin stretch is large, and the stitch line f inhibits the skin stretch.

Next, when the arm lift angle is 0 degree, the marker attached to the height of 20 cm from the hem changes how the hem shift due to pulling by stitching when the arm lift angle is 180 degrees changes. It was confirmed by how much the vertical distance shifted from the distance. The result is as shown in FIG. 12, and the embodiment of the present invention had a smaller amount of displacement than any of the comparative examples, and the amount of displacement increase of the straight gusset 13 compared to Comparative Example 1 was halved.

The material of the gusset 2 used in the embodiment of the present invention may be formed of the same material as that of the body, but if a material that has higher elasticity than the material of the body in the width direction and is difficult to bend is used, Pushing force and upper shoulder tightening force are improved.

Further, the length of the gusset 2 used in the embodiment of the present invention may be longer or shorter than the length from the waist line to the elbow line through the armpit, as shown in FIGS. 13A and 13B. Even if it extends from the vicinity of the waist line M to the vicinity of the elbow line N through the armpit, the same effect is produced. The waist line M refers to the outer peripheral line of the cross section passing through the midpoint of the lower end of the radius and the upper end of the pelvis, and the elbow line N refers to the outer peripheral line of the cross section passing through the elbow head.
In addition, although said Example demonstrated the case of a long sleeve, not only a long sleeve but a short sleeve may be sufficient.

Industrial application fields

As described above, the upper garment of the present invention can apply a push-up force from the gusset to the body, the tightening force of the upper shoulder is reduced, and the gusset and the body are less likely to be pulled by stitches. Therefore, it is particularly suitable as volleyball or baseball wear that raises and lowers arms.
