Description

[Technical field]

[0001] The present invention relates to a collar keeper, a manufacturing method thereof, and a collared garment equipped with the collar keeper, and in particular to a collar keeper for a collared garment that is attached to the collar of a collared garment in a folded state or in a state where the garment is hung from a hanger to maintain the shape of the collar, a manufacturing method thereof, and a collared garment equipped with the collar keeper. [Background technology]

[0002] Conventionally, collar keepers for collared clothing that are attached to the collar of a collared garment to maintain the shape of the collar have been known, for example, to have a main body made of a long, thin, flexible sheet body, as described in Patent Documents 1 and 2. In the conventional collar keepers for collared garments described in the above-mentioned Patent Documents 1 and 2, the main body is designed to be attached between the collar stand and the fold-down collar of the collar of the collared garment in a folded state. In particular, in the conventional collar keeper for collared garments described in Patent Document 2 mentioned above, multiple corrugations are provided on the lower edge of the main body, and when the main body is attached to the collar of a folded collared garment, the peaks of the waves of these multiple corrugations come into contact with the collared garment at multiple contact points, thereby dispersing the contact load and reducing the formation of contact marks on the back of the garment. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2022-16251 [Patent Document 2] JP 2022-112084 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional collar keepers for collared clothing described in Patent Documents 1 and 2 mentioned above, when the collar keepers are attached to the collar of a collared garment hanging from a hanger so that the collared garment is displayed in a store or the like, the weight of the entire collared garment causes part of the hanger to be pressed from below against the fabric of the garment above it, and the fabric pressed against this part of the hanger comes into contact with part of the collar keeper above it. As a result, part of the collar keeper is pushed upward by part of the hanger and the fabric pressed against it, and may move forward or backward through the gap between the collar stand and the turned-down collar part, or may protrude outside the gap between the collar stand and the turned-down collar part. This not only impairs the function of maintaining the shape of the collar, but also causes part of the collar keeper to be visible from the outside, marring the appearance of the displayed collared clothing item. Furthermore, with regard to the conventional collar keeper for collared clothing described in Patent Document 2 mentioned above, when it is attached to the collar of collared clothing while it is hanging from a hanger, when part of the hanger together with the fabric is pressed from below against the difference (wave height) between the multiple wave peaks and valleys on the lower edge of the collar keeper body, the greater the wave height of the waves on the collar keeper body, the greater the pressure that the part of the hanger together with the fabric will be pressed against the collar keeper, resulting in the problem that the back side of the collar keeper body will protrude downward through the gap between the collar stand part and the turned-down collar part on the back side of the collar. Therefore, in recent years, a challenge that has been demanded is how to make the collar keeper less visible from the outside of the collared garment when attached, while preventing the collar from losing its shape and keeping it stable, not only for folded collared garments but also for the collar of collared garments hanging from a hanger.

[0005] Therefore, the present invention has been made to solve the above-mentioned problems of the conventional technology and problems that have been required in recent years, and aims to provide a collar keeper that makes it difficult to see the main body from the outside of the collar of a collared garment when it is folded or hung from a hanger, prevents the collar from losing its shape, and can stably maintain the shape of the collar, a method for manufacturing the same, and a collared garment equipped with a collar keeper.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A collar keeper for a collared garment according to one embodiment of the present invention will now be described with reference to the accompanying drawings. 1 to 3 are front, side and rear views, respectively, of a collar keeper for collared garments according to the present embodiment attached to the collar of a collared garment hung on a hanger. Fig. 4 is an exploded rear view showing the collar stand and turn-up collar of the collar of a collared garment to which the collar keeper for collared garments according to the present embodiment is attached. Fig. 5A is an exploded front view showing the collar keeper for collared garments according to the present embodiment not attached to the collar of a collared garment.

[0010] First, as shown in Figures 1 to 3, a collar keeper 1 for collared clothing according to this embodiment is attached to the collar 4 of a collared garment 2, such as a dress shirt, in a folded state and hung from a hanger to maintain the shape of the collar 4. 1 to 5A, collar keeper 1 specifically has a main body 10 that is removably attached between the outer peripheral surface 6a of collar stand 6 of collar 4 of collar garment 2 and the inner peripheral surface 8a of turned-up collar 8 that is provided at the upper edge of the collar and can be folded back, thereby maintaining the collar shape by being sandwiched between collar stand 6 and turned-up collar 8. Before collar keeper 1 is attached, main body 10 is unfolded into a boomerang shape bent in the middle (roughly V-shaped in plan view), and is made of a flexible thin plate member made of resin (such as polyvinyl chloride resin). In addition, in the manufacturing method of the color keeper 1, for example, the boomerang-shaped main body 10 is formed by punching (pressing) a thin plate material using a die or the like, thereby manufacturing the color keeper 1. In addition, the main body 10 is elastically deformable so that when attached to the outer peripheral surface 6a of the collar portion 6 along the longitudinal direction, it becomes annular, and when not attached to the collar portion 6, it becomes band-like. Furthermore, as shown in FIG. 5A, the main body 10, the details of each part of which will be described later, has a shape that is approximately linearly symmetrical about a line A1 that passes through the center, and when viewed from the front side with the collar keeper 1 attached to the collar 4, it is provided with, from the center side in the left-right direction (the side of the left-right central axis A1 of the main body 10 shown in FIG. 5A) and front side to the outside and rear side in the left-right direction, a locking portion 12, a main body left side portion 14, a main body right side portion 16, a main body left rear portion 18, and a main body right rear portion 20.

First, the left front end 22 and the right front end 24 of the collar stand are provided at the front end and left-right center of the collar stand 6 of the collared garment 2 and are arranged to be overlapped with each other front to back. A collar stand button portion 32 is provided on one side of the collar stand left front end portion 22 and the collar stand right front end portion 24 (for example, the collar stand left front end portion 22 on the far side (rear side) when viewed from the front side). On the other hand, on the other side of the collar stand left front end portion 22 and the collar stand right front end portion 24 (for example, the collar stand right front end portion 24 on the near side (front side) when viewed from the front side), a collar stand button hole portion 34 is provided into which the collar stand button portion 32 is detachably inserted. Next, the left side portion 26 and the right side portion 28 of the collar stand are formed so as to extend longitudinally outwardly and rearwardly with respect to the left front end portion 22 and the right front end portion 24 of the collar stand, respectively. The collar back portion 30 is formed to extend in the longitudinal direction rearward and on the inner left and right sides of the collar left side portion 26 and the collar right side portion 28 . Here, the first collar section S1 from the left front end 22 of the collar stand to the first collar connection part B1 between the left side portion 26 of the collar stand in the longitudinal direction and the back portion 30 of the collar stand, the second collar section S2 from the first connection part B1 to the second connection part B2 between the back portion 30 of the collar stand in the longitudinal direction and the right side portion 28 of the collar stand, and the third collar section S3 from the second connection part B2 to the right front end 24 of the collar stand in the longitudinal direction are each arranged so as to divide the entire circumference of the collar stand portion 6 into three equal parts in the circumferential direction.

[0012] Next, as shown in Figures 1 to 5A, the locking portion 12 of the main body 10 is provided at the center O1 in the left-right longitudinal direction of the main body 10, and includes a locking groove 40 that releasably locks into the collar button portion 32 when inserted into the collar button hole portion 34. Furthermore, when attached to the collar 4 of the collared garment 2, the left side surface portion 14 and the right side surface portion 16 of the main body are formed so as to extend from the fastening portion 12 outward in the left and right longitudinal directions of the main body 10 when viewed from the front side, and are arranged so as to face the outer surfaces of the left side surface portion 26 and the right side surface portion 28 of the collar stand, respectively. Furthermore, the left and right rear portions 18 and 20 of the main body are formed to extend outward in the left-right longitudinal direction from the left outer end portion 14a of the left side portion 14 of the main body and the right outer end portion 16a of the right side portion 16 of the main body, respectively, and are arranged to face the outer surface of the collar rear portion 30. Furthermore, the left and right rear body portions 18 and 20 are each provided with an adjustment portion 42, 44 (left adjustment portion 42, right adjustment portion 44) that allows the circumferential length of the annular main body 10 to be adjusted when attached to the collar 4 of the collared garment 2. The adjustment portions 42, 44 will be described in detail later, but as shown in Fig. 5A, they are provided symmetrically with respect to a center portion O1 in the left-right longitudinal direction of the main body 10.

[0013] Next, FIG. 5B is a partially enlarged expanded front view of the collar keeper 1 for collared garments according to this embodiment shown in FIG. 5A, in which the engaging portion 12 of the main body 10 and its left and right side portions 14, 16 are enlarged. As shown in Figures 1 to 5B, the left outer end portion 14a of the main body left side portion 14 and the right outer end portion 16a of the main body right side portion 16 respectively constitute a main body first connection portion C1 and a main body second connection portion C2 which are connected to the main body left rear portion 18 and the main body right rear portion 20, respectively, located behind them. These first main body connection portion C1 and second main body connection portion C2 are arranged to face the first collar connection portion B1 and second collar connection portion B2, respectively, and are provided with a left cut-out portion 46 and a right cut-out portion 48, respectively, which form curved cuts in the inner lateral side of the main body 10 in the short direction of the lower edges 14b, 16b of the left main body side portion 14 and the right main body side portion 16. The cuts R1, R2 of the left cut-out portion 46 and the right cut-out portion 48 will be described in detail later, but when a collared garment 2 is hung from the hanger H, a part of the hanger H cuts into the cuts R1, R2 in an upwardly concave curve so as to be accessible from below through the fabric of the collared garment 2 above.

[0014] Next, as shown in Figures 1 to 5B, the width W1 (short side width W1) of each of the left main body back portion 18 and the right main body back portion 20 in the short side direction is the same as the width W0 (short side width W0) of the stand collar back portion 30 in the short side direction (W1 = W0). In addition, the concavely curved cuts R1, R2 of the left cut-out portion 46 and the right cut-out portion 48 are formed on the lower edges 14b, 16b (each cut R1, R2) of the left side surface portion 14 and the right side surface portion 16 of the main body 10, which are formed on the inside of the short side of the main body 10 relative to the lower edges 18a, 20a of the left rear surface portion 18 and the right rear surface portion 20 of the main body, respectively, and the cut depth D1 is set to 0.2 to 0.4 or approximately 1 / 3 or less of the short side width W1 of the left rear surface portion 18 and the right rear surface portion 20 of the main body (D1 / W1=0.2 to 0.4, or D1 / W1≦1 / 3). By the way, as an example, the cut depth D1 of the lower edges 14b, 16b (each cut R1, R2) of the left side portion 14 and the right side portion 16 of the main body is set to 1.0 [cm] (D1 = 1.0 [cm]), and the short-side width W1 of the left rear portion 18 of the main body and the right rear portion 20 of the main body is set to 3.2 [cm] (W1 = 3.2 [cm]).

[0015] Next, as shown in FIG. 4, the left side portion 26 of the collar stand includes a left front side portion 26A and a left rear side portion 26B which divide the first collar section S1 in the longitudinal direction into two equal parts, front and rear, and a third collar connection portion B3 which connects the left front side portion 26A and the left rear side portion 26B. In addition, the right side portion 28 of the collar stand includes a right front side portion 28A and a right rear side portion 28B which divide the third section S3 of the collar stand in half longitudinally, and a fourth connection portion B4 which connects the right front side portion 28A and the right rear side portion 28B of the collar stand. Furthermore, each of the collar left rear side surface portion 26B and the collar right rear side surface portion 28B has the same short side width W2 from the rear side to the front side in the longitudinal direction. On the other hand, the lower edges 26a, 28a of the left and right front side portions 26A, 28A of the collar stand are curved so that the short side widths W3 of the left and right front side portions 26A, 28A of the collar stand gradually narrow from the lower ends 26b, 28b of the third and fourth connection portions B3, B4 of the collar stand toward the left and right front end portions 22, 24 of the collar stand, respectively.

[0016] Next, as shown in Figures 1 to 5B, each of the main body left side portion 14 and the main body right side portion 16 includes a main body front left side portion 14A and a main body front right side portion 16A arranged to face the collar stand left front side portion 26A and the collar stand right front side portion 28A, respectively, a main body rear left side portion 14B and a main body rear right side portion 16B arranged to face the collar stand left rear side portion 26B and the collar stand right rear side portion 28B, respectively, and a main body third connection portion C3 and a main body fourth connection portion C4 connecting each of the main body front left side portion 14A and the main body front right side portion 16A to the main body rear left side portion 14B and the main body rear right side portion 16B, respectively. Furthermore, the lower edges 14b, 16b of the main body rear left side surface portion 14B and the main body rear right side surface portion 16B respectively form a left cut-out portion 46 and a right cut-out portion 48. These left cut-out portion 46 and right cut-out portion 48 respectively form concavely curved cuts R1, R2 such that the short-side widths W4 of the main body rear left side surface portion 14B and the main body rear right side surface portion 16B gradually increase from their rear sides toward the front ends 14f, 16f corresponding to the main body third connection portion C3 and the main body fourth connection portion C4, respectively, on the forward side. On the other hand, the front left side portion 14A of the main body and the front right side portion 16A of the main body are each formed so that their lower edges 14d, 16d have a short side width W5 that gradually narrows from the rear ends 14c, 16c corresponding to the third connection portion C3 and the fourth connection portion C4 of the main body, respectively, toward the forward engaging portion 12. Furthermore, the third main body connection portion C3 and the fourth main body connection portion C4 each have a first convex contact P1 and a second convex contact P2 whose lower ends 14e, 16e are capable of contacting the lower ends 26b, 28b of the third base collar connection portion B3 and the fourth base collar connection portion B4, respectively. Here, the short side width W6 of each of the main body third connection portion C3 and the main body fourth connection portion C4 at the first convex contact P1 and the second convex contact P2 is set to be the same as the short side width W7 of each of the collar base third connection portion B3 and the collar base fourth connection portion B4, and also to be the same as the short side width W1 of each of the main body left rear portion 18 and the main body right rear portion 20 (W6 = W7 = W1).

[0017] Next, Figures 5C and 5D are partially enlarged front views of the left adjustment portion 42 and the right adjustment portion 44 of the main body 10 in the expanded front view of the collar keeper 1 for collared garments according to this embodiment shown in Figure 5A. 1 to 3 and 5A to 5D, each adjustment section 42, 44 of the main body 10 is formed to extend in the short direction of the main body left rear section 18 and the main body right rear section 20, and has a plurality (12 pieces) of left adjustment holes 50 and a plurality (12 pieces) of right adjustment holes 52 arranged at equal intervals in the longitudinal direction.

Further, the short side width W10 of the entire locking portion 12 at the center O1 of the main body 10 is set to 2.4 cm (W10=2.4 cm). Furthermore, the projection length L3 of each downward protrusion 58, 60 of the engaging portion 12 of the main body 10 from the lower edges 14d, 16d of the front left side portion 14A of the main body and the front right side portion 16A of the main body to each lower end 58a, 60a is set to 1.4 cm (L3 = 1.4 cm). In addition, the cut depth D1 formed on the inside of the short side of the main body 10 relative to the lower edges 18a, 20a of each of the left and right rear portions 18 and 20 of the main body is set to 1.0 cm (D1 = 1.0 cm), and since the short side width W1 of each of the rear portions 18, 20 of the main body 10 is set to 3.2 cm (W1 = 3.2 cm), D1 / W1 is set to 0.31. The dimensions of each part of the main body 10 of the collar keeper 1 for collared clothing in this embodiment are not limited to the example described above, and can be changed as appropriate depending on the dimensions and shape of the collar of the collared clothing to which the collar keeper 1 is attached.

[0020] Next, the operation of the collar keeper 1 for collared clothing according to this embodiment will be described with reference to Figs. FIG. 6 is a perspective view showing a state in which the collar keeper for collared garments according to this embodiment is attached to the collar of a collared garment hung on a hanger. First, according to the collar keeper 1 for collared garments of this embodiment, when the flexible main body 10 made of a thin resin plate member is attached to the collar portion 4 of the collared garment 2, the collar stand button portion 32 inserted into the collar stand button hole portion 34 of the collar portion 4 of the collared garment 2 is engaged with the engaging groove 40 of the engaging portion 12 of the main body 10 without folding back the folded-over collar portion 8 of the collar portion 4, and the collar stand is attached so as to fit along the surfaces (outer surfaces 6a) of the left and right side portions 26 and 28 of the collar stand and the back portion 30 of the collar stand for the left and right side portions 14 and 16 of the main body, and the left and right back portions 18 and 20 of the main body. As a result, the entire main body 10, which is a thin resin plate member that is strip-shaped when not attached, is elastically deformed (bending deformation and twisting deformation) into a three-dimensional ring shape. At this time, the concavely curved notches R1, R2 of the left notch 46 and the right notch 48 of the main body 10 make it easier to elastically deform the entire main body 10, which is a thin resin plate member that is band-shaped when not attached, into a three-dimensional annular shape through bending and twisting deformation. The circumferential length of the annular main body 10 when worn can be adjusted by adjusting the adjustment parts 42, 44 provided on the left back part 18 of the main body and the right back part 20 of the main body according to the outer circumferential length of the collar stand portion 6 of the collared garment 2. In addition, the annular main body 10 attached to the collar stand 6 of the collar 4 of the collared garment 2 is inserted between the collar stand 6 and the collar turn-down 8 of the collar 4 by folding back the collar turn-down 8 of the collar 4, and each part of the main body 10 other than the fastening part 12 becomes difficult to see from the outside of the collared garment 2. At this time, when the main body 10 is attached to the collar 4 of the collared garment 2 in a folded state, it is difficult to see from the outside of the collared garment 2. In addition, the main body 10 between the surface (outer surface 6a) of the collar stand 6 of the collar 4 and the back surface (inner surface 8a) of the folded-over collar 8 in the folded-over state supports the collar stand 6 from the surface (outer surface 6a) side as well as the back surface (inner surface 8a) side of the folded-over collar 8, thereby preventing the collar 4 from losing its shape and maintaining a stable configuration of the collar 4. Furthermore, when the main body 10 is attached to the collar 4 of the collared garment 2 hung from the hanger H and moves downward together with the collar 4 due to the weight of the entire collared garment 2 hung from the hanger H, part of the hanger H comes into contact from below with the first collar stand connection part B1 between the left collar stand left side part 26 and the collar stand back part 30 of the collared garment 2 and the second collar stand connection part B2 between the collar stand back part 30 and the collar stand right side part 28. At this time, the fabric of the collared garment 2 at the first collar stand connection part B1 and the second collar stand connection part B2, which come into contact with a part of the hanger H, enters from below into the concavely curved notches R1, R2 in the left notch 46 and the right notch 48 of the first main body connection part C1 and the second main body connection part C2, which face the first collar stand connection part B1 and the second collar stand connection part B2, respectively. Here, the width W1 in the short direction of each of the left and right back portions 18 and 20 of the main body is the same as the width W0 in the short direction of the collar back portion 30, and in the concavely curved cuts R1, R2 of the left and right cuts 46, 48, the cut depth D1 formed on the inside of the short direction of the main body 10 relative to the lower edges 18a, 20a of the left and right back portions 18 and 20 of the main body, respectively, is set to 0.2 to 0.4 or approximately 1 / 3 or less of the width W1 in the short direction of each of the left and right back portions 18 and 20 of the main body (D1 / W1=0.2 to 0.4, or D1 / W1≦1 / 3). As a result, a part of the hanger H is pressed appropriately into the concavely curved cuts R1, R2 of the left cut-out 46 and the right cut-out 48 of the main body 10, respectively, through the fabric of the collared garment 2 above it. As a result, the main body 10 is fixed within the gap area between the collar stand 6 and the turned-down collar portion 8 of the collar portion 4, and the main body 10 can be made to fit between the collar stand 6 and the turned-down collar portion 8 of the collar portion 4 without the front portion of the main body 10 protruding from the gap area between the collar stand 6 and the turned-down collar portion 8 of the collar portion 4 into the external area in front of it, or the rear portion of the main body 10 protruding from the gap area between the collar stand 6 and the turned-down collar portion 8 of the collar portion 4 into the external area behind or below it. Therefore, even when the main body 10 is attached to the collar 4 of the collared garment 2 hung by the hanger H, it can always be stably held within the gap area between the collar stand 6 and the turned-down collar 8 of the collar 4. As a result, the main body 10 attached to the collar 4 of the collared garment 2 hung by the hanger H is made difficult to see from the outside of the collared garment 2, and the shape of the collar 4 is prevented from being distorted, so that the shape of the collar 4 can be stably maintained. Furthermore, since the main body 10 attached to the collar 4 of the collared garment 2 hung by the hanger H can be prevented from protruding in the front-to-back or downward directions from the gap area stored between the collar stand 6 and the collar turn-down 8, the forward projection dimension of the displayed item can be reduced when the collared garment 2 hung by the hanger H is displayed in a store or the like, thereby reducing the display space while increasing the freedom of layout.

[0021] Incidentally, in an experiment conducted by the inventors to verify the behavior of the collar keeper 1 of this embodiment when attached to the collar 4 of a collared garment 2 hung from a hanger H, as a comparative example, verification was also conducted for a case in which the cutting depth D1 of each of the cuts R1, R2 on the left side portion 14 and the right side portion 16 of the collar keeper 1 was set to a range other than 0.2 to 0.4 (or 1 / 3 or less) relative to the short-side width W1 of each of the left back portion 18 and the right back portion 20 of the main body. In this case, the verification result showed that the larger the cut depth D1 is set, the greater the amount that the part of the hanger H facing each cut R1, R2 and the fabric of the garment 2 are pushed into each cut R1, R2 from below, and therefore the back portions 18, 20 of the annular main body 10 move downward and rearward from the lower end of the collar stand back portion 30 of the collar 4 of the collared garment 2, and protrude from the state where it is attached in the gap between the collar stand portion 6 and the turned-down collar portion 8 of the collar 4 of the collared garment 2 as shown in Figures 2 and 3, which is not a preferable wearing and using manner. On the other hand, as a further comparative example, verification results showed that when the cutting depth D1 is eliminated, the entire annular body 10 moves significantly forward, which increases the forward projection dimension of the collared garment 2 when hung by the hanger H, which is not a desirable wearing and using manner.

[0022] Next, as shown in FIG. 5B, in the collar keeper 1 for collared garments of this embodiment, when the main body 10 is attached to the collar stand 6 of the collared garment 2, the lower edges 14d, 16d of the front left side portion 14A and the front right side portion 16A of the main body are formed so that the short side width W5 gradually narrows from the rear ends 14c, 16c corresponding to the third main body connection portion C3 and the fourth main body connection portion C4, respectively, toward the forward engagement portion 12. This allows the main body front left side surface portion 14A and the main body front right side surface portion 16A to be easily elastically bent and twisted so that the main body 10 becomes annular. This allows the front left side portion 14A and the front right side portion 16A of the main body to be smoothly attached and blended into the fourth collar stand section S4 and the fifth collar stand section S5, which extend from the opposing third collar stand connection portion B3 and fourth collar stand connection portion B4 to the left front end portion 22 and the right front end portion 24 of the collar stand. In addition, the lower edges 14b, 16b of the rear left side portion 14B and the rear right side portion 16B of the main body form a left cut-out portion 46 and a right cut-out portion 48, respectively, and the left cut-out portion 46 and the right cut-out portion 48 form a concave curved cut-out whose short side width W4 gradually increases from the rear side toward the front ends 14f, 16f corresponding to the third main body connection portion C3 and the fourth main body connection portion C4, respectively, on the front side. As a result, when the collared garment 2 is folded, the lower edges 14b, 16b of the rear left side portion 14B and the rear right side portion 16B of the main body are prevented from coming into contact with the lower edges 26c, 28c of the opposing rear left side portion 26B and rear right side portion 28B of the collar stand, thereby preventing wrinkles and the like due to contact. Furthermore, when the collared garment 2 is hung by the hanger H, the left cut-out portion 46 and the right cut-out portion 48 of the main body 10, together with the first collar stand connection portion B1 and the second collar stand connection portion B2, respectively, receive part of the hanger H, while preventing the main body 10 from protruding in the front-rear direction or downward. Furthermore, regardless of whether the collared garment 2 is folded or hung from the hanger H, the first convex contact P1 and the second convex contact P2 of the lower ends 14e, 16e of the third main body connection portion C3 and the fourth main body connection portion C4 can be brought into contact with the lower ends 26b, 28b of the third collar stand connection portion B3 and the fourth collar stand connection portion B4, respectively, and can make point contact with a part of the collared garment 2. This reduces the contact area between the first convex contact P1 and the second convex contact P2 of the main body 10 and a part of the collared garment 2, making it less likely that the first convex contact P1 and the second convex contact P2 of the main body 10 will leave contact marks on the collared garment 2.

[0023] Furthermore, as shown in Figures 3, 5C and 5D, with the collar keeper 1 for collared garments of this embodiment, after the main body 10 is attached between the collar stand 6 and the collar turn-down 8 of the collar 4 of the collared garment 2, when adjusting the adjustment parts 42, 44 provided on the left back part 18 and the right back part 20 of the main body respectively according to the outer circumferential length of the collar stand 6 of the collared garment 2, at least the left locking protrusion 54 of the left adjustment part 42 can be inserted and locked into any one of the multiple (12) right adjustment holes 52 of the right adjustment part 44, or the right locking protrusion 56 of the right adjustment part 44 can be inserted and locked into any one of the multiple (12) left adjustment holes 50. Therefore, the main body 10 can be securely fixed in a ring shape according to the outer circumferential length along the surface (outer circumferential surface 6a) of the collar stand 6 of the collared garment 2, thereby preventing the main body 10 from rattling when worn. Furthermore, when the main body 10 is attached to a collared garment 2, simply by adjusting the adjustment parts 42, 44, it can be easily made into a ring-shaped shape according to the outer circumferential length along the surface (outer circumferential surface 6a) of the collar stand portion 6 of the collared garment 2, which is very convenient. Furthermore, by inserting and engaging the left locking protrusion 54 of the left adjustment part 42 into any one of the multiple (12) right adjustment holes 52 of the right adjustment part 44, and by inserting and engaging the right locking protrusion 56 of the right adjustment part 44 into any one of the multiple (12) left adjustment holes 50 of the left adjustment part 42, the main body 10 can be more securely fixed in a ring-shaped shape corresponding to the outer circumferential length along the surface (outer circumferential surface 6a) of the collar stand part 6 of the collared garment 2, thereby effectively suppressing rattling of the main body 10 when worn.

[0024] Furthermore, as shown in FIG. 5B, with the collar keeper 1 for collared garments of this embodiment, regardless of whether the collared garment 2 is folded or hung from a hanger H, the third convex contact P3 and the fourth convex contact P4 of the left lower protrusion 58 and the right lower protrusion 60 of the fastening portion 12 of the main body 10 can be brought into contact with the lower end 24a of the right front end portion 24 of the collar stand, in which the collar stand buttonhole portion 34 is provided, and can make point contact with a part of the collared garment 2. This reduces the contact area between the third convex contact P3 and the fourth convex contact P4 of the main body 10 and a part of the collared garment 2, making it less likely that the third convex contact P3 and the fourth convex contact P4 of the main body 10 will leave contact marks on the collared garment 2.

[0025] Furthermore, as shown in Figures 1 to 3 and 6, a collared garment 2 equipped with a collar keeper 1 for collared garments according to this embodiment can be provided which is attached to the gap between the collar stand 6 and the turned-down collar 8 of the collar 4 so as not to be visible from the outside of the collared garment 2, and the main body 10 does not protrude from the gap between the collar stand 6 and the turned-down collar 8 of the collar 4 even when the collared garment 2 is folded or hung from a hanger, preventing the collar 4 from losing its shape and enabling the configuration of the collar 4 to be stably maintained. In the collar keeper 1 of the present embodiment described above, the range of "D1 / W1" has been described as 0.2 to 0.4 or approximately 1 / 3 or less. However, since the width W1 of the back portions 18, 20 of a collar keeper 1 intended for clothing with a short short side width W0 of the back portion 30 of the collar stand will be narrow, the lower limit of "D1 / W1" may be approximately 0.25. Also, if the material or thickness of the collar keeper is changed to suppress the repulsive force when it is bent, the lower limit of "D1 / W1" may be an extremely small value such as about 0.1. However, it has been experimentally confirmed that for a collar keeper 1 that can accommodate a variety of conventional collar stands, it is preferable to have a condition closer to D1:W1=1:3. Therefore, it is confirmed that "D1 / W1" should be 1 / 3 or less. [Explanation of symbols]
