Description

Technical Field

[0001] The present invention relates to a pajama top worn during sleep, and more particularly to a pajama top that can facilitate turning over during sleep and suppress deterioration of sleep quality.

Background Art

[0002] It is known that people repeatedly turn over many times during sleep, from supine to lateral, or from lateral to supine. Specifically, it is said that ideally about 20 turns over should be performed during a single sleep period, in order to prevent excessive burden on part of the body and achieve comfortable sleep. In general, pajamas (hereinafter referring to pajama tops unless otherwise specified) often have a slightly loose design compared to shirts worn for going out, and when lying down, the excess fabric tends to create resistance when turning over, which leads to deterioration of sleep quality. In addition, loose pajamas tend to have their sleeves and hems rolled up little by little due to movements during sleep, and once the pajamas are rolled up, they are more likely to create further resistance when turning over, which is thought to lead to even greater deterioration of sleep quality.

[0003] To address such problems, a technique that focuses on the frictional resistance between the worn pajamas and the mattress, and suppresses factors that hinder natural turning over by reducing the catching of the worn pajama top on the mattress, is disclosed in Utility Model Registration No. 3183432 (Patent Document 1). The pajama top disclosed in Patent Document 1 is a top having at least a front body part and a back body part, wherein the top includes a high-slip fabric member with a smooth surface on the outer fabric of the back body part, and the high-slip fabric member is characterized in that at least the back collar part, the left shoulder part, the right shoulder part, the left side part and the right side part are sewn by sewing means.

[0004] [Patent Document 1] Utility Model Registration No. 3183432 Gazette [Overview of the project] [Problems that the invention aims to solve]

[0005] However, although the pajama top disclosed in Patent Document 1 mentioned above is made of specially designed fabric, it cannot be said to be sufficiently effective in suppressing factors that hinder turning over in sleep. Furthermore, pajamas with specially designed armholes (simply made larger) to reduce resistance to turning over in sleep are on the market, but these also cannot be said to be sufficiently effective in suppressing factors that hinder turning over in sleep.

[0006] The present invention was developed in view of the above-mentioned problems of the prior art, and its purpose is to provide a pajama top to be worn while sleeping that facilitates turning over in bed and suppresses a decline in sleep quality. [Means for solving the problem]

[0007] To achieve the above objective, the pajama top according to the present invention employs the following technical means. In other words, the pajama top according to the present invention is characterized in that the main 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 can be configured to be 55 cm or more. More preferably, when the pajama top is placed on a flat surface, the tangent line at the base of the underarm seam of the armhole line, which extends from the shoulder tip to the base of the underarm seam, can be configured to point toward the center of the garment. More preferably, the angle of intersection between the tangent line of the sleeve cutout line at the base of the sleeve and the vertical line can be configured to be between 5 and 12 degrees.

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

[0010] The pajama top according to the present invention provides a pajama top that can be worn while sleeping to facilitate turning over in bed and suppress a decline in sleep quality. [Brief explanation of the drawing]

[0011] [Figure 1] This figure shows an example of a pajama top 100 according to an embodiment of the present invention, and is a diagram showing it placed on a flat surface (product base). [Figure 2] This is a partial diagram (pattern-based) of the garment 100 placed on a flat surface, illustrating the features of garment 100 shown in Figure 1. [Figure 3] This diagram shows the standard dimensions (finished dimensions) to explain the features of garment 100 in Figure 1. [Figure 4] Figure 1 is a diagram illustrating the effects of garment 100. [Modes for carrying out the invention]

[0012] The 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, (although the pajama top according to the present invention is not limited to men's wear) a men's pajama top 100 is shown in Figure 1 (product base). Figure 2 (pattern base) is a partial view of this top 100 placed on a plane, with Figure 2(A) showing the front body 110, Figure 2(B) showing an enlarged view of the area 2B shown in Figure 2(A), and Figure 2(C) showing the back body 120 and sleeve portion 130. Note that in Figure 2, since this top 100 is symmetrical, only one half of either the left or right side is shown (indicated by the front center line FC and the back center line BC). Furthermore, whether it is a product base or a pattern base, it satisfies the range of numerical limitations (described in the claims), which are the technical features of the pajama top according to the present invention, which will be described later.

[0013] In the following explanation, for this garment 100, the length L(1) from the shoulder tip 134 to the underarm base (synonymous with the sleeve bottom) 132 will be defined as the sleeve width L(1), the length L(2) from the shoulder tip 134 to the opposite shoulder tip 134 will be defined as the shoulder width L(2), the length L(3) of the cuff will be defined as the cuff width L(3), the length L(4) from the underarm base 132 to the opposite underarm base 132 will be defined as the body width L(4), the length (circumference) of the armhole will be defined as the armhole length AH, and the waist measurement will be defined as W. Here, the armhole length AH is equal to the sleeve width L(1) × 2. As shown in these figures, the garment 100 is composed of a front panel 110, a back panel 120, and sleeves 130, and the fabric of the garment, which is composed of the front panel 110, back panel 120, and sleeves 130, is a woven fabric.

[0014] The front panel 110 and the back panel 120 are sewn together in front of (towards the abdomen) the shoulder line KL of the top 100 (the back panel 120 covers the front (towards the abdomen) of the shoulder area), as shown in Figure 1. When this garment 100 is placed on a flat surface, a portion of the back panel 120 is visible at the shoulder. This garment 100 is not simply an enlarged version of the armhole length AH described in the prior art, but rather has the following technical features: (A) the armhole length AH is enlarged in comparison to the shoulder width L(2); (B) the upper end of the armhole (shoulder tip 134) is lowered (as a drop-shoulder type, with the shoulder line KL directed significantly downward (as shown by the white arrow in Figure 1, the shoulder line KL is directed significantly downward relative to the horizontal line HL); (C) the body width L(4) is narrowed relative to the shoulder width L(2) or the waist dimension W is tightened (shaped) to reduce excess fabric in the body (front panel 110 and back panel 120); and (D) the cuff width L(3) is narrowed relative to the sleeve width L(1) to make the cuff narrower and reduce excess fabric in the sleeve 130. Furthermore, although not limited to this garment 100, it may have pockets 112 on the front panel 110.

[0015] The technical features of this garment 100 will be described in more detail below. The ratio of shoulder width L(2) to armhole length AH (sleeve width L(1) × 2) is set to 1.1 to 1.21 (1.1 or more and 1.21 or less). It should be noted that, unlike conventional designs, the armhole length AH has not simply been increased, but rather, based on the shoulder width L(2), the armhole length AH has been increased to a point where it is slightly smaller than the shoulder width L(2) (1 / 1.21 to 1 / 1.1) relative to the shoulder width L(2) (i.e., the ratio of shoulder width L(2) to armhole length AH (sleeve width L(1) × 2) is never less than 1).

[0016] And, the (absolute value of this) shoulder width L(2) is set to a large value of 55 cm or more. As an example, the standard dimensions (finished dimensions) of this upper garment 100 are shown in FIG. 3. As described above, the pajama upper garment according to the present invention is not limited to men's use, and women's sizes are smaller than the men's sizes shown in FIG. 3, so the lower limit value of the shoulder width L(2) in the pajama upper garment according to the present invention is as small as 55 cm as described above, compared to the shoulder width L(2) shown in FIG. 3. This is significantly different from the conventional women's pajama upper garments, whose shoulder width is about 50 cm for LL size, in that the lower limit of the shoulder width L(2) in the pajama upper garment according to the present invention is 55 cm.

[0017] Next, as shown in FIG. 2(A) and FIG. 2(B), in a state where this upper garment 100 is placed on a flat surface, the tangent line SGL at the underarm base portion 132 of the armhole line SG (synonymous with armhole curve) extending from the shoulder tip 134 to the underarm base portion 132 is directed toward the body center (on the front center line FC side). More specifically, the intersection angle θ (deg) between the tangent line SGL at the underarm base portion 132 of the armhole 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] By designing in this manner, it is possible to realize a drop-shoulder type upper garment 100 in which the (absolute value of the) shoulder width L(2) is large, the armhole length AH is (relatively) large (based on the shoulder width L(2)), and the shoulder line KL is largely directed downward (as shown by the outlined arrow in FIG. 1, the shoulder line KL is largely directed downward relative to the horizontal line HL). By designing in this way, the muscle mass required for turning over during sleep can be reduced (test results will be described later), making it easier to turn over during sleep and suppressing deterioration in sleep quality.

[0019] Further, in this upper garment 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). With respect to the sleeve width L(1) that has been increased in this way, the cuff width L(3) is tapered so as to gradually narrow (the ratio of the final cuff width L(3) that is gradually tapered relative to the sleeve width L(1) is 1 / 1.8 to 1 / 1.65), and a design in which the cuff width L(3) is made relatively narrow relative to the sleeve width L(1) is provided, so that the fabric of the sleeve portion 130 excess is reduced, so that the main fabric of the sleeve portion 130 is prevented from clinging to the body when the wearer turns over, turning over during sleep is facilitated, and a decrease in sleep quality can be suppressed.

[0020] Further, in this upper garment 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 down to 0.8 to 0.93 relative to the shoulder width L(2), and a design in which the body width L(4) is made relatively narrow relative to the shoulder width L(2) is provided, so that the fabric excess of the body (the front body 110 and the back body 120) is reduced, the main fabric of the body is prevented from clinging to the body when the wearer turns over, turning over during sleep is facilitated, and a decrease in sleep quality can be suppressed.

[0021] The functions and effects when the wearer turns over while wearing the pajama upper garment 100 having such a configuration will be described with reference to FIG. 4. The test method was carried out as follows: this upper garment 100 (a drop shoulder type in which not only the armhole length AH is larger than that of Comparative Example 2, but also the shoulder line KL is largely directed downward (as shown by the outlined arrow in FIG. 1, the shoulder line KL is largely directed downward relative to the horizontal line HL)) was taken as an example; an upper garment in which the armhole length AH was simply made larger than that of a normal upper garment was taken as Comparative Example 2; and a normal upper garment (an upper garment whose armhole length AH is not large and which is not a drop shoulder type) was taken as Comparative Example 1.

[0022] The measurement environment was 25°C and 40% RH. The subjects first lay on their backs, slid their arms to the side over 5 seconds, rolled over over 5 seconds, returned to their backs while bringing their arms back over another 5 seconds, and then rested for another 5 seconds, repeating this simulated rolling motion. Figure 4 shows the results (integrated electromyographic values) of measuring muscle mass in the areas necessary for turning over in bed (in this test, the trapezius, biceps brachii, triceps brachii, and pectoralis major muscles).

[0023] In Comparative Example 2, which has a larger armhole length (AH) compared to Comparative Example 1, which is a standard upper garment, 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 brachii muscles is higher in Comparative Example 2 than in Comparative Example 1. Compared to Comparative Example 2, the embodiment with an even larger armhole length (AH) and a drop-shoulder design requires less muscle mass in all three muscles—trapezius, biceps brachii, triceps brachii, and pectoralis major—than Comparative Example 1, and the reduction in muscle mass for the trapezius and pectoralis major is even greater than in Comparative Example 2.

[0024] Based on these test results, it can be seen that it is possible to reliably reduce the muscle mass in the areas necessary for turning over in bed (in this test, the trapezius, biceps, triceps, and pectoralis major muscles). As described above, the pajama top according to this embodiment can be worn while sleeping to facilitate turning over in bed and suppress a decline in 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 indicated by the claims rather than by the foregoing description, and all modifications within the meaning and scope equivalent to the claims are intended to be included. [Industrial applicability]
