Abstract

PROBLEM TO BE SOLVED: To obtain a garment for ski jump competition enabling a player to select the garment capable of moving the center of gravity of lift force according to the player's posture and peculiarity, and further capable of increasing a flying distance by reducing a random formation of wrinkle position. SOLUTION: This garment for ski jump competition is the one-piece type one obtained by sewing and composing plural garment parts, and has back switch lines 16 and 16 formed in mutually nonparallel from about shoulder position of the back body to the waist position at right and left symmetrical positions of back center A as a symmetrical axis by sewing garment parts on back body 6. The both switch lines 16 and 16 contributes generation of lifting power and when the structure of the switching lines has distances becoming gradually narrower from the shoulder position to the waist position, the center of gravity of the lifting power shifts to the front and when the distances increases from the shoulder position to the waist position, the center of gravity of the lifting power shifts to the back.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in clothes for ski jumping competitions used for ski jumping competitions.

[0002]

2. Description of the Related Art In a ski jumping competition, since a cloth having a layered structure mainly made of a urethane resin sheet or the like is used, wrinkles of clothes to be worn become large, and a vortex of air formed behind the wrinkles. Is known to have a significant effect on flight distance. For example, in jumping clothes sewn in a flying position, a large down wrinkle is formed in the abdomen when taking a descent position, and acceleration does not increase. Wrinkles are formed, and the flight distance is not extended.

[0003] The same applies to the sleeve portion, and the occurrence of wrinkles has a significant effect on the flight distance in a ski jumping competition. The position and shape were regarded as problems. However, both the downhill posture and the flying posture are slightly different depending on the competitor, and there is a problem that the best one cannot be uniquely determined.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and enables to select clothes whose lift center of gravity has been shifted in accordance with the posture and habit of an athlete, and wrinkles. It is an object of the present invention to provide a ski jumping garment capable of extending a flight distance by suppressing occurrence of a position at random.

[0005]

That is, a garment for a ski jumping competition according to the present invention is a one-piece garment for a ski jumping competition in which a plurality of garment parts are sewn and assembled. Therefore, the gist of the present invention is to provide a structure in which the back switching lines which are formed by sewing the clothing parts of the back body and which are not parallel to each other are formed on the right and left sides of the back center with respect to the symmetry axis.

[0006] The two back switching lines, which are formed by sewing the clothing parts of the back body and become non-parallel to each other on the left and right sides of the back center with respect to the symmetry axis, contribute to the generation of the lift of the back part, and the two back switching lines. When the distance between the shoulders is gradually narrowed from the shoulder to the waist, the lift center of gravity at the time of flight moves forward, and when the distance is gradually widened from the shoulder to the waist, the structure at the time of flight The lift center of gravity moves backward.

Further, the present invention is characterized in that a structure of a sleeve-elbow switching line that crosses a sleeve tube downward and rearward at a substantially elbow of a sleeve of a garment is provided for suturing clothing parts of the sleeve. In addition, the structure of the sleeve-elbow switching line allows the airflow relating to both arms to flow rectified to the rear of the elbow to reduce the occurrence of Karman vortices, so that the flight distance can be increased.

[0008] At the time of suturing the above-mentioned garment parts, the stitching margin of the switching line is made smaller than 1 cm, the sewing thread is cut with synthetic resin thread having relatively high rigidity, and the seam is made hard, so that the rectifying effect by the switching line is achieved. Can be reliably exhibited.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a ski jumping garment according to the present invention. 1 (a) is a back view of a back-lifting center-of-gravity ski jumping garment, FIG. 1 (b) is a back view of a waist-lifting center of gravity type ski jumping garment, and FIG. 2 is a bi-ski jumping garment. FIG.

The garment for ski jumping shown in this drawing has a one-piece structure in which the outer garment 1 and the trousers garment 2 are stitched together by a waist switching line 3.
A fabric material having a layer structure mainly composed of a urethane resin sheet or the like is used. The outer garment 1 has a structure in which a front body part 5, a back body part 6, and a sleeve part 7 are stitched and divided by a raglan switching line 4, and a zipper extending from a neckline 8 is provided at the center of the front body part 5. 9 extends to the vicinity of the rise of the pants-side garment 2.

The back neck 8 (arrow A) is lowered (the two-dot chain line indicates the position of the conventional back neck) as in the front neck. Further, the sleeve portion 7 is sewn in a tubular shape by a shoulder switching line 10 configured to the cuff 11 by approaching the front body side and a sleeve switching line 12 configured from the valley position of the armhole to the cuff 11. It has a structure in which a thumb hole 13 is formed.

Further, the sleeve 7 has a sleeve elbow switching line 14 which is located substantially at the elbow of the sleeve 7 and crosses the sleeve sleeve downward and downward.
Extends from the base of the shoulder switching line 10 (arrow B) to the cuff 11 of the sleeve switching line 12 (arrow C), and a cuff opening / closing fastener 15 is provided from the cuff 11.

The back switching lines 16, 16 of the present invention are provided on the left and right sides of the back body portion 6 (dashed line D) of the back body portion 6 of the sewn clothing for ski jumping, as the axis of symmetry, and the left and right clothing parts of the back body. It is configured as non-parallel structures formed by suturing. The back switching lines 16, 16
Figure 1 for back-lifting center-of-gravity ski jumping clothing
As shown in (a), with the back center as the axis of symmetry, the space between the two lines is gradually narrowed from the shoulder to the waist on the left and right sides of the back center. In this case, as shown in FIG. 1 (b), the center of the back is a symmetrical axis, and the left and right sides are gradually widened from the shoulder to the waist.

The above-mentioned switching lines of the waist switching line 3, the raglan switching line 4, the shoulder switching line 10, the sleeve switching line 12, the sleeve elbow switching line, and the back switching line 16 are connected to each other as shown in FIG. A part having a cut edge 17 at the edge of the part is sewn with a sewing thread 18. The sewing margin of the sewn portion is about 7 mm, which is slightly narrower than the conventional sewing margin, and the sewing thread 18 is also a Tetron filament 40 /. Use a relatively hard and highly elastic material such as No. 3.

When the clothing for ski jumping competition having the above-described configuration assumes a flying posture as shown in FIG.
The lift center of gravity is displaced back and forth by the back lift center of gravity form (a) and the waist lift center of gravity form (b), which affects the jump posture of the competitor.

That is, FIG. 1 shows a structure in which both back switching lines 16, 16 gradually narrow the gap from the shoulder to the waist.
In the structure of (a), the air on the back side compressed from both sides toward the waist by the structure of the two back switching lines 16 and 16 is separated from the back surface at an early stage after entering from the shoulder. Therefore, the center of gravity of the lift moves relatively to the front position (arrow E).

FIG. 1 shows a structure in which both back switching lines 16, 16 gradually widen the interval from the shoulder to the waist.
In the structure of (b), the air on the back side diffused from both sides toward the waist by the structure of the back switching lines 16 and 16 moves along the back to the waist while entering from the shoulder. Therefore, the center of gravity of the lift moves to a relatively rear position (arrow F).

The amount of forward / backward movement of the lift center of gravity varies depending on the direction and angle of the two back switching lines 16, 16, and good results can be obtained by properly using the flight posture and physique of the competitor and the wind condition during the competition. Bring.

The sleeve elbow switching line 7 formed on the sleeve 7 is
The shoulder switching line 10 extends from the base of the sleeve (arrow B) to the cuff 11 of the sleeve switching line 12 (arrow C) so as to be located substantially at the elbow of the sleeve 7 and cross the sleeve tube downward and downward. It is configured. For this reason, the air that has entered the front side of the elbow acts to reduce the generation of Karman vortices by rectifying and flowing along the sleeve elbow switching line 14 to the rear of the elbow, which also increases the flight distance. It is.
