Description

[Technical field]

[0001] The present invention relates to a pajama top worn while sleeping, and more particularly to a pajama top that makes it easy to turn over while sleeping and prevents deterioration of sleep quality. [Background technology]

[0002] It is known that people turn over in their sleep from their back to their side or from their side to their back many times. Specifically, it is said that it is ideal to turn over about 20 times in one sleep session in order to prevent excessive strain on parts of the body and to achieve a comfortable sleep. Generally, pajamas (which refers to the top of pajamas unless otherwise specified below) tend to be slightly looser than shirts worn for going out, and when lying down, the excess fabric tends to create resistance when turning over in sleep, which leads to poor sleep quality. In addition, loose pajamas tend to have sleeves and hems that roll up little by little as you move while sleeping, and once the pajamas are rolled up, they become even more of a resistance when turning over in sleep, which is thought to lead to even poorer sleep quality.

[0003] To address these problems, a technology is disclosed in Utility Model Registration No. 3183432 (Patent Document 1) that focuses on the frictional resistance between the pajamas worn and the mattress, and reduces the chance of the upper part of the pajamas getting caught on the mattress, thereby suppressing factors that prevent natural turning over in sleep. The pajama top disclosed in Patent Document 1 is a top having at least a front body portion and a back body portion, and the top is characterized in that the outer fabric of the back body portion is made of a highly slippery fabric material with a smooth surface, and that at least the back of the collar, the left shoulder portion, the right shoulder portion, the left armpit portion and the right armpit portion are sewn by a sewing means.

[0004] [Patent Document 1] Utility Model Registration No. 3183432 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the pajama top disclosed in the above-mentioned Patent Document 1 is made of an innovative fabric material, but the effect of suppressing factors that prevent turning over in sleep is not sufficient. Furthermore, pajamas with an improved armhole size (simply enlarged armholes) to reduce resistance to turning over are on the market, but these also are not sufficiently effective in suppressing factors that prevent turning over in sleep.

[0006] The present invention was developed in consideration of the above-mentioned problems of the prior art, and its purpose is to provide a pajama top to be worn while sleeping that makes it easy to turn over while sleeping and prevents a decline in sleep quality. [Means for solving the problem]

[0007] In order to achieve the above object, the pajama top of the present invention employs the following technical measures. In other words, the pajama top of the present invention is characterized in that the body fabric constituting the front body, back body and sleeves is made of woven fabric, and the ratio of shoulder width to armhole length is set to 1.1 to 1.21.

[0008] Preferably, the shoulder width is set to 55 cm or more. More preferably, when the pajama top is placed on a flat surface, a tangent line at the base of the sleeve of the sleeve cutting line extending from the shoulder to the base of the sleeve can be configured to point toward the center of the body. More preferably, the angle of intersection between a tangent to the sleeve cutting line at the base of the underarm and a vertical line is set to 5 degrees to 12 degrees.

[0009] More preferably, the ratio of the sleeve width to the cuff width may be set to 1.65 to 1.8. More preferably, the ratio of the body width to the shoulder width may be set to 0.8 to 0.93. Effect of the Invention

[0010] According to the pajama top of the present invention, it is possible to provide a pajama top that can be worn while sleeping and that makes it easier to turn over in sleep, thereby preventing a decline in the quality of sleep. [Brief description of the drawings]

[Diagram 2] 2 is a partial view (based on a paper pattern) of upper garment 100 of FIG. 1 placed on a flat surface to explain the characteristics of upper garment 100. FIG. [Diagram 3] FIG. 2 is a diagram showing standard dimensions (finished dimensions) for explaining the features of the top 100 in FIG. [Figure 4] FIG. 2 is a diagram for explaining the function and effect of the upper garment 100 of FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] A pajama top 100 according to an embodiment of the present invention will be described in detail below with reference to the drawings. As an example of such pajamas, a pajama top 100 for men (although the pajama top according to the present invention is not limited to men's) is shown in FIG. 1 (product base). Also, FIG. 2 (pattern base) is a partial view of the top 100 laid out on a plane, with FIG. 2(A) showing the front body 110, FIG. 2(B) showing an enlarged view of the area 2B shown in FIG. 2(A), and FIG. 2(C) showing the back body 120 and sleeves 130. Note that in FIG. 2, since the top 100 is symmetrical (showing the front center line FC and the back center line BC), only one half of the body is drawn (left or right). Also, whether it is a product base or a pattern base, the range of numerical limitations (described in the claims) which is the technical feature of the pajama top according to the present invention described later is satisfied.

[0013] In the following description of this top 100, the length L(1) from the shoulder tip 134 to the sleeve bottom base (synonymous with the sleeve bottom) 132 is defined as the sleeve width L(1), the length L(2) from the shoulder tip 134 to the opposite shoulder tip 134 is defined as the shoulder width L(2), the length L(3) of the cuff is defined as the cuff width L(3), the length L(4) from the sleeve bottom base 132 to the opposite sleeve bottom base 132 is defined as the body width L(4), the length (circumference) of the armhole is defined as the armhole length AH, and the waist size is defined as W. Here, the armhole length AH is the sleeve width L(1) x 2. As shown in these figures, the top 100 is composed of a front body 110, a back body 120, and sleeves 130, and the body fabric composed of the front body 110, the back body 120, and the sleeves 130 is a woven fabric.

[0014] The front body 110 and the back body 120 are sewn together in front (on the abdominal side) of the shoulder line KL of the top 100 (the back body 120 covers up to the front (abdominal side) of the shoulder). When this top 100 is placed on a flat surface, a part of the back body 120 is visible at the shoulder. This top 100 does not simply have an increased armhole length AH as described in the prior art, but has the following technical features: (A) the armhole length AH is increased in comparison with the shoulder width L(2), (B) the upper end of the armhole (shoulder tip 134) is dropped downward (a drop shoulder type in which the shoulder line KL is directed significantly downward (as shown by the outlined arrow in FIG. 1, the shoulder line KL is directed significantly downward with respect to the horizontal line HL)), (C) the body width L(4) is narrowed relative to the shoulder width L(2) and the waist dimension W is narrowed (shaped) to reduce excess fabric in the body (front body 110 and back body 120), and (D) the cuff width L(3) is narrowed relative to the sleeve width L(1) to narrow the cuffs and reduce excess fabric in the sleeve portion 130. The top 100 also includes, but is not limited to, a pocket 112 on the front body 110 .

[0015] The technical features of this top 100 will be explained in more detail below. The ratio of shoulder width L(2) to armhole length AH (sleeve width L(1) x 2) is set to 1.1 to 1.21 (1.1 or more and 1.21 or less). What should be noted here is that the armhole length AH has not simply been increased as in the past, but has been increased to a level slightly smaller than shoulder width L(2) (1 / 1.21 to 1 / 1.1) based on shoulder width L(2) (the armhole length AH does not exceed shoulder width L(2), i.e., the ratio of shoulder width L(2) to armhole length AH (sleeve width L(1) x 2) does not become less than 1).

[0016] The absolute value of this shoulder width L(2) is set to be large, at 55 cm or more. As an example, the standard dimensions (finished dimensions) of this top 100 are shown in FIG. 3. As mentioned above, the pajama top according to the present invention is not limited to men's wear, and the dimensions for women are smaller than those for men shown in FIG. 3, so the lower limit of the shoulder width L(2) of the pajama top according to the present invention is 55 cm, as mentioned above, which is smaller than the shoulder width L(2) shown in FIG. 3. The major difference is that the shoulder width of conventional women's pajama tops is about 50 cm for LL size, while the lower limit of the shoulder width L(2) of the pajama top according to the present invention is 55 cm.

[0017] 2(A) and 2(B), with the upper garment 100 placed on a flat surface, a tangent SGL at the sleeve base 132 of the sleeve carving line (synonymous with sleeve carving line) SG from the shoulder 134 to the sleeve base 132 faces the center of the body (toward the front centerline FC). More specifically, the intersection angle θ (deg) between the tangent SGL at the sleeve base 132 of the sleeve carving line SG and the vertical line VL is 5 degrees to 12 degrees (5 degrees or more and 12 degrees or less), preferably 6 degrees or more, and more preferably 7 degrees or more.

[0018] This design makes it possible to realize a drop-shoulder type upper garment 100 in which the shoulder width L(2) (its absolute value) is large, the armhole length AH (relatively to the shoulder width L(2)), and the shoulder line KL is directed significantly downward (as shown by the outlined arrow in FIG. 1, the shoulder line KL is directed significantly downward with respect to the horizontal line HL). This design also reduces the muscle mass required when turning over in sleep (test results will be described later), making it easier to turn over while sleeping and preventing a decline in sleep quality.

[0019] In addition, in this top 100, the ratio of the sleeve width L(1) to the cuff width L(3) is set to 1.65 to 1.8 (1.65 or more and 1.8 or less). As described above, the armhole length AH is increased, which inevitably increases the sleeve width L(1). However, the cuff width L(3) is gradually narrowed relative to the increased sleeve width L(1) (the ratio of the cuff width L(3) to the sleeve width L(1) is 1 / 1.8 to 1 / 1.65), and the cuff width L(3) is designed to be narrower relative to the sleeve width L(1). By reducing the excess, the main fabric of the sleeve portion 130 is prevented from clinging to the body when turning over in sleep, making it easier to turn over in sleep and preventing deterioration of sleep quality.

[0020] In addition, in this top 100, the ratio of the body width L(4) to the shoulder width L(2) is set to 0.8 to 0.93 (0.8 or more and 0.93 or less). In this way, the body width L(4) is narrowed (0.8 to 0.93) relative to the shoulder width L(2), and the design has a narrower body width L(4) relative to the shoulder width L(2). This reduces excess fabric in the body parts (front body part 110 and back body part 120) and prevents the body fabric from clinging to the body when turning over in sleep, making it easier to turn over while sleeping and preventing a decrease in sleep quality.

[0021] The effect of turning over in sleep while wearing the pajama top 100 having such a configuration will be described with reference to FIG. The test method was as follows, using this top 100 (a drop shoulder type in which not only the armhole length AH is longer than that of comparison example 2 but also the shoulder line KL is directed significantly downward (the shoulder line KL is directed significantly downward relative to the horizontal line HL as shown by the white arrow in Figure 1)) as an example, a top in which the armhole length AH was simply longer than that of a normal top as comparison example 2, and a normal top (a top in which the armhole length AH is neither longer nor a drop shoulder type) as comparison example 1.

[0022] The measurement environment was 25°C and 40% RH, and the subject first lay on his back, then slid his arms to the side over five seconds, turned over over five seconds, returned his arms to their original position over another five seconds, and then rested for another five seconds, simulating the motion of turning over. Figure 4 shows the results (integrated electromyographic values) of measuring the muscle mass of the areas required for turning over in bed (in this test, the trapezius, biceps, triceps, and pectoralis major).

[0023] In Comparative Example 2, in which the armhole length AH is increased compared to Comparative Example 1 which is a normal top, the required muscle mass for the trapezius and pectoralis major muscles is lower in Comparative Example 2 than in Comparative Example 1, but the required muscle mass for the biceps and triceps muscles is higher in Comparative Example 2 than in Comparative Example 1. In comparison with Comparative Example 2, an embodiment having an armhole length AH greater than that of Comparative Example 2 and being of a drop shoulder type requires less muscle mass for the trapezius, biceps, triceps and pectoralis major than in Comparative Example 1, and the required muscle mass for the trapezius and pectoralis major is significantly less than that of Comparative Example 2.

[0024] Based on the results of this test, it can be seen that it is possible to definitely reduce muscle mass in the areas required for turning over in bed (in this test, the trapezius, biceps, triceps, and pectoralis major muscles). As described above, the pajama top according to the present embodiment can be worn while sleeping to facilitate turning over in sleep and prevent deterioration of sleep quality. It should be noted that the embodiments disclosed herein are illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims, not the above description, and is intended to include all modifications within the meaning and scope of the claims. [Industrial Applicability]

[0025] The present invention is suitable for use as a pajama top worn while sleeping, and is particularly suitable for use as a pajama top that makes it easy to turn over while sleeping and prevents deterioration in sleep quality. [Explanation of symbols]
