Hence, when the arm A is raised or rotated, sleeves 4 are prevented from dropping, and a garment body is prevented from unnecessarily largely moving. Further, a portion of the armhole 5 on a front garment body 2 side is designed to pass through a deltopectoral groove between a deltoid muscle E and a pectoralis major muscle D of the wearer, whereby the upward retainability of the sleeves and the position stability of the garment body are further improved.

Description

TECHNICAL FIELD

[0001] The present invention relates to an upper garment that is less likely to lose its shape and can provide a comfortable wear feeling even during strenuous exercise such as sports, because armhole shapes of sleeves of the upper garment are devised.

BACKGROUND ART

[0002] Up to now, upper garments that are expected to provide wear feelings improved by devising sleeve shapes are disclosed in Patent Literature 1 and Patent Literature 2.

[0003] Unfortunately, these upper garments are likely to lose their shapes and cannot provide comfortable wear feelings during strenuous exercise such as sports.

[0004] A conventional upper garment 11 used for sports shirts and the like includes a front garment body 12, a back garment body 13, and sleeves 14. The sleeves 14 and the front garment body 12 are sewn to each other through armholes 15, and the sleeves 14 and the back garment body 13 are sewn to each other through the armholes 15.

[0005] Examples of the sleeves 14 having shapes standard for the conventional upper garment 11 include a set-in sleeve illustrated in FIG. 4 to FIG. 6 and a raglan sleeve illustrated in FIG. 7 to FIG. 9.

[0006] Particularly the set-in sleeve is considered as a prototype of sleeves, and is adopted for the most items.

[0007] As illustrated in FIG. 4 to FIG. 6, the set-in sleeve is designed such that a sleeve peak point 16 of an armhole 15 passes through a shoulder tip point S.

[0008] Features of the set-in sleeve are as follows.

[0009] 1) The set-in sleeve is designed such that the wear comfort becomes best in the state where the arm is naturally lowered.

[0010] 2) The set-in sleeve has a simple structure, and thus is easily suited to every design.

[0011] Next, as illustrated in FIG. 7 to FIG. 9, the raglan sleeve is obtained by developing the set-in sleeve, and is more improved in functionality.

[0012] As illustrated in FIG. 7 to FIG. 9, the raglan sleeve is designed such that a portion of an armhole 15 on the front garment body 12 side connects a front armpit point F to the front side of a neck side point N.sub.2 and that a portion of the armhole 15 on the back garment body 13 side connects a back armpit point H to the back side of the neck side point N.sub.2. A shoulder tip portion at a sleeve peak of the raglan sleeve is rounded.

[0013] The raglan sleeve is used particularly in the case where a portion around the shoulder is desired to be seamless, and features of the raglan sleeve are as follows.

[0014] 1) The raglan sleeve follows the roundness of the shoulder tip of the human body, and the sleeve edge thereof is not significantly lowered, whereby the wear comfort and the exercise performance are considered.

[0015] 2) The armhole is wide, and this enables the arm to easily pass therethrough.

[0016] 3) Because there is no seam around the shoulder, a seam allowance is less likely to contact the skin.

[0017] Moreover, Patent Literature 3 discloses a bicycle shirt worn by cyclists and the like, in which each armhole is formed in a special shape as illustrated in FIG. 10 and FIG. 11, in order to: cause almost no unnecessary crease even at a posture at which a wearer rides on a bicycle; and reduce stresses applied to the body of the wearer such as a stiffening feeling and a twitching feeling of the shirt.

CITATION LIST

Patent Literature

[0018] Patent Literature 1: Japanese Patent Laid-Open No. 2003-129316 [0019] Patent Literature 2: Japanese Utility Model No. 3064858 [0020] Patent Literature 3: Japanese Design No. 1430374

SUMMARY OF INVENTION

Technical Problem

[0021] In the upper garment 11 such as a shirt worn for strenuous exercise such as sports, an arm A is larger in displacement than a body trunk part B when the arm is raised or rotated. Hence, each sleeve 14 that covers the arm A large in displacement needs to have a function (upward retainability) of preventing the sleeve 14 from dropping during a motion and reducing twitches caused by contact with an arm upper part. Moreover, the garment body that covers the body trunk part A small in displacement needs to have a function (position stability) of reducing twitches caused by inward/outward or frontward/backward displacement of the garment body during a motion.

[0022] As a result of measuring a change in shape of a shoulder upper part during arm raising, as illustrated in FIG. 4 to FIG. 6, the arm A and the body trunk part B are bent around trapezius muscle stop points when the shoulder is rotated outward. Then, trapezius muscle stop points b.sub.1, b.sub.2, and b.sub.3 as arm bending points move toward the neck side point N.sub.2 as the shoulder is rotated outward. In the case of an average adult man, the distances from the neck side point N.sub.2 to the trapezius muscle stop points b.sub.1, b.sub.2, and b.sub.3 are as follows: the distance from the trapezius muscle stop point b.sub.1 to the neck side point N.sub.2 in an arm lowered state is 75 mm; the distance from the trapezius muscle stop point b.sub.2 to the neck side point N.sub.2 in a state where the arm A is raised at an angle of 90.degree. as indicated by an alternate long and short dash line in FIG. 4 is 60 mm; and the distance from the trapezius muscle stop point b.sub.3 to the neck side point N.sub.2 in a state where the arm A is raised at an angle of 150.degree. as indicated by a broken line in FIG. 4 is 45 mm. In this way, as the arm A is raised from its lowered state, the trapezius muscle stop points b.sub.1, b.sub.2, and b.sub.3 move toward the neck side point N.sub.2.

[0023] Unfortunately, the conventional set-in sleeve and the conventional raglan sleeve are designed without considering the positions of the arm bending points, that is, the trapezius muscle stop points b.sub.1, b.sub.2, and b.sub.3 when the arm A is raised or rotated.

[0024] For example, as illustrated in FIG. 4 to FIG. 6, the armhole 15 of the set-in sleeve is designed to suit the shape of the arm A from the shoulder tip point S when the arm A is naturally lowered. That is, because fitness standards are placed on a static state of the human body, the sleeve drops during arm raising, and twitches are caused by contact with the arm upper part. In this regard, the upward retainability of the sleeve is not considered.

[0025] Moreover, as illustrated in FIG. 6, the armhole 15 of the set-in sleeve is located on the outer side of a border (a region in light black) between the body trunk part B small in displacement and the arm A large in displacement. Hence, when the arm A is rotated, the garment body contacts the arm A large in displacement, and the garment body thus does not fit the body trunk part B, so that even the garment body that is originally undesired to move moves unfavorably.

[0026] Meanwhile, the raglan sleeve is designed to follow the roundness of the shoulder tip of the human body to some degree, considering wear comfort. Accordingly, although not as obviously as the set-in sleeve, the sleeve edge of the raglan sleeve faces downward. Hence, the sleeve drops during arm raising, and twitches are caused by contact with the arm upper part. In this regard, the upward retainability of the sleeve is not considered.

[0027] Moreover, as illustrated in FIG. 7 to FIG. 9, the armhole 15 of the raglan sleeve is located across the border between the body trunk part B small in displacement and the arm A large in displacement. Hence, when the arm A is rotated, the sleeve 14 contacts the arm A large in displacement, and the garment body thus does not fit the body trunk part B, so that even the garment body that is originally undesired to move moves unfavorably.

[0028] Moreover, the bicycle shirt (a product of GOLDWIN INC., in which cutting design "AERO FORM" is adopted) of Patent Literature 3 is designed considering a static motion (posture retention) such that almost no unnecessary crease is caused at a posture at which a wearer rides on a bicycle and that a stiffening feeling and a twitching feeling of the shirt are prevented. When the arm is raised or rotated, the sleeve drops, and the garment body unnecessarily largely moves.

[0029] The cause for this is as follows. As illustrated in FIG. 10 and FIG. 11, the sleeve peak point 16 of the bicycle shirt of Patent Literature 3 is also located on the outer side of the trapezius muscle stop point b.sub.1 in an arm lowered state, similarly to general set-in sleeves. Hence, during a dynamic motion (a motion of raising or rotating the arm), it is difficult for the sleeve 14 to follow the motion of the arm, so that even the garment body that is originally undesired to move moves unfavorably.

[0030] In view of the above, the present invention has an object to provide an upper garment that prevents sleeves from dropping and a garment body from unnecessarily largely moving, is less likely to lose its shape, and can provide a comfortable wear feeling, even during strenuous exercise such as sports, particularly, when the arm is raised or rotated.

Solution to Problem

[0031] The present invention provides an upper garment including an armhole having a sleeve peak point that is located between: a trapezius muscle stop point on a shoulder ridge line of a wearer in an arm lowered state; and a trapezius muscle stop point on the shoulder ridge line of the wearer in an arm raised state.

[0032] As the arm is raised from its lowered state, the position of the trapezius muscle stop point on the shoulder ridge line moves toward a neck side point.

[0033] Accordingly, the sleeve peak point of the armhole is located between: the trapezius muscle stop point on the shoulder ridge line of the wearer in the arm lowered state; and the trapezius muscle stop point on the shoulder ridge line of the wearer in the arm raised state, whereby an arm bending point during arm raising and the armhole coincide with each other. Hence, when the arm is raised or rotated, sleeves can be prevented from dropping, and a garment body can be prevented from unnecessarily largely moving.

[0034] Further, a portion of the armhole on a front garment body side is designed to pass through a deltopectoral groove between a deltoid muscle and a pectoralis major muscle of the wearer. With this design, the armhole is located on a border between the arm part large in displacement and a body trunk part small in displacement. Hence, the upward retainability of the sleeves and the position stability of the garment body become excellent.

[0035] A lower portion of the armhole on the front garment body side is designed to pass through a front armpit point of the wearer, a portion of the armhole on a back garment body side is designed to pass through a scapular spine protruding part of the wearer, and a lower portion of the armhole on the back garment body side is designed to pass through a back armpit point of the wearer. With these designs, the armhole follows the border between the arm large in displacement and the body trunk part small in displacement. Hence, the upward retainability of the sleeves and the position stability of the garment body become more excellent.

[0036] Moreover, the portion of the armhole on the front garment body side is concaved so as to follow a concave of the deltopectoral groove between the deltoid muscle and the pectoralis major muscle of the wearer, whereby the wear feeling can be further improved.

Advantageous Effects of Invention

[0037] In an upper garment according to the present invention, an arm bending point during arm raising and an armhole coincide with each other. Hence, the upper garment is less likely to lose its shape and can provide a comfortable wear feeling even during strenuous exercise such as sports.

DESCRIPTION OF EMBODIMENTS

[0049] An upper garment 1 according to the present invention includes a front garment body 2, a back garment body 3, and sleeves 4. The sleeves 4 and the front garment body 2 are sewn to each other through armholes 5, and the sleeves 4 and the back garment body 3 are sewn to each other through the armholes 5.

[0050] A sleeve peak point 6 of each armhole 5 in the upper garment 1 according to the present invention is located between: a trapezius muscle stop point b.sub.1 on a shoulder ridge line L of a wearer in an arm A lowered state; and a trapezius muscle stop point b.sub.3 on the shoulder ridge line L of the wearer in an arm A raised state (indicated by a broken line in each of FIG. 1 and FIG. 2).

[0051] As the arm A is raised from its lowered state, as illustrated in FIG. 1 and FIG. 2, the position of the trapezius muscle stop point b.sub.1 on the shoulder ridge line L moves to b.sub.2 and then b.sub.3 toward a neck side point N.sub.2.

[0052] In FIG. 2, C denotes a trapezius muscle. Moreover, in FIG. 1, D denotes a pectoralis major muscle, E denotes a deltoid muscle, and a deltopectoral groove between the deltoid muscle E and the pectoralis major muscle D is hatched. In FIG. 1 to FIG. 3, S denotes a shoulder tip point, and N.sub.1 denotes a neck back center point.

[0053] In the case of an average adult man, the distances from the neck side point N.sub.2 to the trapezius muscle stop points b.sub.1, b.sub.2, and b.sub.3 are as follows: the distance to the trapezius muscle stop point b.sub.1 in the arm lowered state is 75 mm; the distance to the trapezius muscle stop point b.sub.2 in a state where the arm A is raised at an angle of 90.degree. is 60 mm; and the distance to the trapezius muscle stop point b.sub.3 in a state where the arm A is raised at an angle of 150.degree. is 45 mm. As the arm A is raised from its lowered state, the trapezius muscle stop points b.sub.1, b.sub.2, and b.sub.3 move toward the neck side point N.sub.2.

[0054] Accordingly, in the case of designing the upper garment 1 worn by the average adult man, an allowance is set such that the sleeve peak point 6 of the armhole 5 is located within a range of 45 mm to 75 mm from the shoulder tip point S toward the neck side point N.sub.2.

[0055] In this way, the sleeve peak point 6 of the armhole 5 is located between: the trapezius muscle stop point b.sub.1 on the shoulder ridge line L of the wearer in the arm A lowered state; and the trapezius muscle stop point b.sub.3 on the shoulder ridge line L of the wearer in the arm A raised state, whereby an arm bending point during arm raising and the armhole 5 coincide with each other. Hence, when the arm A is raised or rotated, the sleeves 4 can be prevented from dropping, and the front garment body 2 and the back garment body 3 can be prevented from unnecessarily largely moving.

[0056] Then, a portion of the armhole 5 on the front garment body 2 side is designed to pass through the deltopectoral groove between the deltoid muscle E and the pectoralis major muscle D of the wearer. With this design, the armhole 5 is located on a border between the arm A large in displacement and a body trunk part B small in displacement. Hence, the upward stability of the sleeves and the position stability of the garment body become excellent.

[0057] A lower portion of the armhole 5 on the front garment body 2 side is designed to pass through a front armpit point F of the wearer, a portion of the armhole 5 on the back garment body 3 side is designed to pass through a scapular spine protruding part G of the wearer, and a lower portion of the armhole 5 on the back garment body 3 side is designed to pass through a back armpit point H of the wearer. With these designs, the armhole 5 is located on the border between the arm A large in displacement and the body trunk part B small in displacement. Hence, the upward retainability of the sleeves and the position stability of the garment body become more excellent.

[0058] Moreover, as indicated by an arrow I in FIG. 3, the portion of the armhole 5 on the front garment body 2 side is concaved so as to follow a concave of the deltopectoral groove between the deltoid muscle E and the pectoralis major muscle D of the wearer, whereby the wear feeling is further improved.

[0059] In FIG. 2, the position of the trapezius muscle stop point b.sub.3 on the shoulder ridge line L of the wearer in the arm A raised state is closer to the neck back center point N.sub.1 by 11% to 17% of the distance (a half of the shoulder width) between the neck back center point N.sub.1 and the shoulder tip point S, from the trapezius muscle stop point b.sub.1 on the shoulder ridge line L of the wearer in the arm A lowered state.

[0060] Moreover, the position of the trapezius muscle stop point b.sub.3 on the shoulder ridge line L of the wearer in the arm A raised state is closer to the shoulder tip point S by 62% to 66% of the distance (a half of the shoulder width) between the neck back center point N.sub.1 and the shoulder tip point S, from the neck back center point N.sub.1.

[0061] Accordingly, the sleeve peak point 6 of the armhole 5 in the upper garment 1 according to the present invention is located closer to the neck back center point N.sub.1 by 11% to 17% from the trapezius muscle stop point b.sub.1 on the shoulder ridge line L of the wearer in the arm A lowered state.

[0062] Moreover, the position of the trapezius muscle stop point b.sub.3 on the shoulder ridge line L of the wearer in the arm A raised state, for positioning the sleeve peak point 6 of the armhole 5 in the upper garment 1 according to the present invention, may be determined to be closer to the shoulder tip point S by 62% to 66% of the distance (a half of the shoulder width) between the neck back center point N.sub.1 and the shoulder tip point S, from the neck back center point N.sub.1.

[0063] Next, Table 1 shows results of measurement whose subjects are ten adult men (average height: 170.6 cm), the measurement concerning the positions of the trapezius muscle stop points and the like. Here, the average value and the standard deviation are calculated for each parameter, and "`average value-standard deviation` to `average value+standard deviation`" is defined as the range of each parameter.

[0064] In Table 1, the measurement subjects A to J are ten adult men, whose average height is 170.6 cm.

[0065] In Table 1, the half of the shoulder width means the distance between the neck back center point N.sub.1 and the shoulder tip point S, b.sub.1 means the distance (mm) from the neck back center point N.sub.1 to the trapezius muscle stop point in the arm lowered state, b.sub.3 means the distance (mm) from the neck back center point N.sub.1 to the trapezius muscle stop point in the state where the arm is raised at the angle of 150.degree., the BP moving amount means the moving distance (mm) of the trapezius muscle stop point toward the inner side (toward the neck back center point N.sub.1) from b.sub.1 in the arm lowered state to b.sub.3 in the state where the arm is raised at 150.degree., the b.sub.3 moving ratio means the ratio (%) of the position of b.sub.3 to the half of the shoulder width (=[the position of b.sub.3/the half of the shoulder width].times.100), and the BP moving ratio means the ratio (%) of the BP moving amount to the half of the shoulder width (=[the BP moving amount/the half of shoulder width].times.100).

[0066] As described above in Table 1, the "BP moving amount" means the moving distance of the "trapezius muscle stop points b.sub.1, b.sub.2, and b.sub.3" toward the neck back center point N.sub.1 from the arm lowered state to the state where the arm is raised at 150.degree.. Accordingly, the sleeve peak point 6 is set such that the trapezius muscle stop point b.sub.3 on the shoulder ridge line L of the wearer in the arm A raised state is closer to the neck back center point N.sub.1 by 11% to 17% of the distance between the neck back center point N.sub.1 and the shoulder tip point S, from the trapezius muscle stop point b.sub.1 on the shoulder ridge line L of the wearer in the arm A lowered state. In this way, the arm bending point during arm raising and the armhole can be made coincident with each other.

[0067] Moreover, from Table 1, the "b.sub.3 position ratio" (the ratio of the "position of b.sub.3" to the "half of the shoulder width") is 62% to 66%. Here, the position of b.sub.3 means the distance between the "neck back center point N.sub.1" and the "trapezius muscle stop point" in the state where the arm is raised at 150.degree.. Accordingly, the sleeve peak point 6 is set such that the trapezius muscle stop point b.sub.3 on the shoulder ridge line L of the wearer in the arm A raised state is closer to the shoulder tip point S by 62% to 66% of the distance between the neck back center point N.sub.1 and the shoulder tip point S, from the neck back center point N.sub.1. Also in this way, the arm bending point during arm raising and the armhole can be made coincident with each other.

[0068] Note that, although Table 1 shows the results of the measurement whose subjects are adult men, it is considered that similar ratios are obtained for both the "BP moving ratio" and the "b.sub.3 position ratio" even in the case where the measurement subjects are other than adult men.
