Description

Technical Field

[0001] The present invention relates to a connection unit for a multiple movable headband that rotatably connects at least two headbands to each other.

Background Art

[0002] The inventor of the present application has previously proposed a multiple movable headband (title of the invention: hairstyle retainer for wearing a hat) in Patent Document 1, for the purpose of easily suppressing crushing of bangs and hair at the top of the head when wearing a hat, and allowing easy arrangement of the hairstyle after wearing the hat.

[0003] The hairstyle retainer of Patent Document 1 comprises: a main body portion having an open partial annular shape and having elasticity capable of changing the interval of the open portion, the main body portion including a coil-shaped first hair retaining portion having a predetermined pitch, and two head fixing portions provided at both ends of the first hair retaining portion and forming the open portion; an arc-shaped movable hair retaining portion having a coil-shaped second hair retaining portion having a predetermined pitch; and a main body connection portion that pivotally attaches the movable hair retaining portion above each head fixing portion of the main body portion.

[0004] In this way, the head fixing portions of the main body portion are fixed to both sides of the head, the movable hair retaining portion is pivoted within a desired range, and the first hair retaining portion and the second hair retaining portion are attached to different predetermined hair positions, so that pressing of the hair by the hat is suppressed at at least two positions. Since the first and second hair retaining portions are formed in a coil shape having a predetermined pitch, hair including the roots of the hair at the attached position enters the coils, thereby suppressing crushing of the hair at that portion caused by the pressing of the hat. Thus, crushing in the vicinity of the roots of the hair at least at the bangs and the top of the head is suppressed, and disorder of the hairstyle caused by wearing a hat is prevented.

[0005] As described above, according to this hairstyle retainer, crushing of bangs, hair on the top of the head and the like after wearing a hat can be easily suppressed, and disorder of the hairstyle after wearing a hat can be easily arranged.

[0015] Next, embodiments for carrying out this invention will be described with reference to the figures. Figure 1 shows the overall configuration of a first embodiment of a multi-movable headband and a connecting unit for a multi-movable headband, and Figures 2 and 3 show the configuration of its main parts.

[0016] As shown in Figure 1, the multi-unit movable headband K consists of at least two headbands K1 and K2, each formed in a roughly C-shape or U-shape using elastic wire, with a pair of fixing parts 2,2 at both ends and a hairstyle holding part 1 in the middle having multiple hair holding parts 10, and each headband K1 and K2 is connected via a multi-unit movable headband connection unit U1. The multi-unit movable headband connection unit U1 (hereinafter simply referred to as the connection unit U1) has a structure that connects the headbands K1 and K2 so that they can rotate relative to each other by rotatably connecting each fixing part 2,2 of one headband K1 to each fixing part 2,2 of the other headband K2.

[0017] In this case, the multi-movable headband K is a double-movable type. Each headband K1, K2 is formed in a roughly C-shape using elastic wire, and its ends are a pair of fixing parts 2, 2 for elastically pressing and fixing to both sides of the (human) head. The intermediate part between each fixing part 2, 2 is positioned to span from the top of the (human) head to both sides of the head, and forms a hairstyle holding part 1 having multiple hair holding parts 10 that lift and hold the hair away from the scalp.

[0018] In this case, one headband, K1, is basically worn on the top of the head as the first headband (hereinafter referred to as the first headband K1), while the other headband, K2, is basically worn on the front of the head where the bangs are located as the second headband (hereinafter referred to as the second headband K2), and each has slightly different configurations as follows.

[0019] The first headband K1 is made of stainless steel or other metal wire and is formed in a roughly C-shape, with a longer overall length than the second headband K2.

[0020] The ends of the First Headband K1 are formed as a pair of fixing parts 2,2 for securing the First Headband K1 to both sides of the head (of a human head). In this case, each of these fixing parts 2,2 is roughly the length of a rod, extending from the middle of the ear in the vertical direction behind the ear to the bottom of the ear, and is relatively gently curved when viewed from the front (along both sides of the head) and straight when viewed from the side. In this case, the parts of each fixing part 2,2 that come into contact with both sides of the head when the headband K1 is worn are flattened and covered with a semi-cylindrical resin cover (not shown). There is an open space between these fixing parts 2,2, and by pulling each fixing part 2,2 apart outwards, the gap in the open space can be further widened, allowing the First Headband K1 to be worn on the head. Furthermore, in this case, a plastic ball is attached as decoration 3 to the lower end of each fixing part 2,2, in other words, to both ends of the First Headband K1. Furthermore, this decoration 3 can be made of synthetic resin or metal, and can be changed in various ways, such as a ball, or small plates, blocks, or frames in the shape of triangles, squares, or stars, or small plates, blocks, or frames in the shape of animals or plants, or even small plates, blocks, or frames in the shape of various characters.

[0021] The middle section of the First Headband K1, that is, the space between each fixing section 2,2, is positioned to span from the top of the head to both sides of the head, and is formed as a hairstyle holding section 1 consisting of multiple hair holding sections 10 that lift and hold the hair away from the scalp. In this case, the hairstyle holding section 1 is roughly the length that extends between the upper and lower midpoints of each ear behind both ears, and in a front view (along the top of the head and both sides of the head), it has a roughly arc shape. The multiple hair holding sections 10 are formed in a circular coil shape with a predetermined pitch and height. In particular, in this hair holding section 1, the pitch spacing and height of the coils are formed to gradually become slightly narrower and lower from the center of the arc toward both ends, so that hair is passed through and held between each coil. Note that the shape of the coils is not limited to circles, and may also be triangular or square. In this case, the surface of the hairstyle holding section 1 is covered with synthetic resin, rubber, or cloth.

[0022] The second headband K2 is made of stainless steel or other metal wire and is formed in a roughly C-shape, with a shorter overall length compared to the first headband K1.

[0023] The ends of the second headband K2 are formed as a pair of connecting parts 2,2 for connecting to the respective fixing parts 2,2 of the first headband K1, and as a pair of fixing parts 2,2 for fixing the second headband K2 to both sides of the head (of a human head). In this case, each of these fixing parts 2,2 extends roughly from above the ear to the middle of the ear in the vertical direction behind the ear, and in a relatively gentle arc shape when viewed from the front (along both sides of the head), and in a straight line shape when viewed from the side. There is an open space between these fixing parts 2,2, and by pulling each fixing part outward and apart from each other, the gap in the open space is further widened, making it possible to attach the second headband to the head.

[0024] The middle section of the second headband K2, that is, the space between each fixing section 2,2, is positioned to span from the forehead to both sides of the head (of a human head) and is formed as a hairstyle holding section 1 consisting of multiple hair holding sections 10 that lift and hold the bangs away from the scalp. In this case, the hairstyle holding section 1 is roughly the length that extends between the upper and lower midpoints of each ear behind both ears and has a roughly arc shape when viewed from the front (along the top and sides of the head). The multiple hair holding sections 10 are formed in a circular coil shape with a predetermined pitch and height. In particular, in this hair holding section 1, the pitch spacing and height of the coils are formed to gradually become slightly narrower and lower from the center of the arc toward both ends, so that hair is passed through and held between each coil. Note that the shape of the coils is not limited to circles, and may be triangular, square, or the like. Also, in this case, the surface of the hairstyle holding section 1 is covered with synthetic resin, rubber, or cloth.

[0025] As shown in Figure 2, the connection unit U1 comprises a fixed-side connection part U11 provided on each fixed part 2,2 of one headband K1 (or K2) and having a rotating guide part 4 with a circular cross-section, and a movable-side connection part U12 provided on each fixed part 2,2 of the other headband K2 (or K1) and having a rotating guide part 5 with a circular or arc-shaped cross-section that can rotatably engage on the rotating guide part 4 of the fixed-side connection part U11. Furthermore, this connection unit U1 also has a rotation range restricting stopper 6 between the rotating guide part 4 of the fixed-side connection part U11 and the rotating guide part 5 of the movable-side connection part U12, which restricts the rotation range of the movable-side connection part U12 relative to the fixed-side connection part U11.

[0026] Figure 2 also shows a specific example of the connection unit U1. As shown in Figure 2, in this connection unit U1, one of the fixed-side connection part U11 or the movable-side connection part U12 is made of a sphere, and the sphere is provided on each of the fixed parts 2,2 of one headband K1 (or K2), and the other is made of an oval or rectangular frame-shaped arc-shaped member that is arc-shaped along the spherical surface of the sphere, and the arc-shaped frame-shaped member is provided on each of the fixed parts 2,2 of the other headband K2, and the fixed parts 2,2 of one headband K1 (or K2) are passed through the frame of the arc-shaped frame-shaped member and are connected so as to be rotatable along the sphere.

[0027] In this case, the fixed-side connecting part U11 is a sphere, or a ball. The spherical surface of this ball forms the rotating guide part 4 with a circular cross-section. This fixed-side connecting part (ball) U11 is fixed through each of the fixing parts 2,2 of the First Headband K1 and attached near the top of each of the fixing parts 2,2 of the First Headband K1.

[0028] In this case, the movable connecting part U12 is an oval (or rectangular) frame-shaped member that exhibits an arc shape along the spherical surface of the fixed connecting part U11. This movable connecting part U12 is provided at the lower end of each fixing part 2,2 of the other headband K2 (or K1). In this case, since each fixing part 2,2 is rod-shaped, their lower ends are extended and a part of the lower end is bent to form an oval frame-shaped member that can be inserted into each fixing part 2,2 of one headband K1 and can engage with the fixed connecting part (ball) U1, and is formed in an arc shape along the spherical surface of the fixed connecting part (ball) U1, so that each movable connecting part U12 is integrally provided at the lower end of each fixing part 2,2 of the other headband K2.

[0029] In this case, the lower ends of each fixing part 2,2, in other words, the ends of each arc-shaped frame member, are bent back toward the rod-shaped body of each fixing part 2,2 so as to follow the spherical surface of the ball of the fixing-side connecting part U1, and are bent back toward or near the body, so as to ensure that these lower ends do not protrude around the ball. Also, in this case, the lower ends of these fixing parts 2,2 may or may not be in contact with the rod-shaped body of the fixing part 2,2. Here, the lower ends of the fixing parts 2,2 are brought close to the body of the fixing part 2,2 but are not in contact with it. Furthermore, if the lower ends of these fixing parts 2,2 are in contact with the body of the fixing part 2,2, they may or may not be fixed together by welding or other means. By not fixing the lower ends of the fixing part 2 to the body of the fixing part 2, each connecting part U1, U2 can be separated, and each headband K1, K2 can be used separately.

[0030] In this case, the ends of each arc-shaped frame member, which are the lower ends of each fixing part 2,2, may be bent back towards the rod-shaped body of each fixing part 2,2 so as shown in Figure 3, so as to follow the spherical surface of the ball of the fixing side connecting part U1, and then be further bent along the (inner) side surface of the body, so as to ensure that these lower ends do not protrude around the ball. In this case as well, the lower ends of these fixing parts 2,2 may or may not be in contact with the rod-shaped body of the fixing part 2,2. Furthermore, if the lower ends of these fixing parts 2,2 are in contact with the body of the fixing part 2,2, they may or may not be fixed together by welding or other means.

[0031] As a result of this bending process, as shown in Figure 2, each of these connecting parts U12, that is, each arc-shaped frame member, has, at the lower part of each fixing part 2,2, one annular portion 51 that extends in a substantially annular shape downward toward the rear side with respect to the front-to-back direction of the head, one straight portion 52 that extends slightly in a straight line from this annular portion 51 in a direction substantially perpendicular to the rod-shaped body of each fixing part 2,2, another annular portion 53 that extends in a substantially annular shape upward toward the rear side with respect to the one annular portion 51 in parallel with this straight portion 52, and another straight portion 54 that extends parallel to the straight portion 52 from this annular portion 53, that is, the lower end of each fixing part 2,2. Thus, each of these arc-shaped frame members is a circular cross-section rotating guide portion 5 that can rotatably engage on the rotating guide portion 4 of the fixed-side connecting part U11, and each of the straight portions 52 and 54 is provided between the rotating guide portion 4 of the fixed-side connecting part U11 and the rotating guide portion 5 of the movable-side connecting part U12, forming a rotating range restricting stopper 6 that restricts the rotation range of the movable-side connecting part U12 relative to the fixed-side connecting part U11.

[0032] In this way, the first headband K1 and the second headband K2 are connected by combining the fixed-side connecting part U11 and the movable-side connecting part U12. In this case, each arc-shaped frame member of the second headband K2 passes through its frame, that is, between each annular-shaped part 51, 53, and is held between each annular-shaped part 51, 53 by each straight-shaped part 52, 54, so that each arc-shaped frame member is rotatable on the spherical surface of each ball, that is, the movable-side connecting part U12 is rotatable relative to the fixed-side connecting part U11. Thus, the first headband K1 and the second headband K2 are connected so that the second headband K2 is rotatable relative to the first headband K1. Furthermore, the connection between the ball and the arc-shaped frame member allows the second headband K2 to rotate relative to the first headband K1. When the second headband K2 is opened relative to the first headband K1, one straight section 52 of the movable connecting part U12, i.e., one rotation range restricting stopper 6, abuts against the rod-shaped body of each fixing section 2,2 of the first headband K1, restricting the movement of the second headband K2 in the opening direction. When the second headband K2 is closed relative to the first headband K1, the other straight section 54, i.e., the other rotation range restricting stopper 6, abuts against the rod-shaped body of each fixing section 2,2 of the first headband K1, restricting the movement of the second headband K2 in the closing direction. The second headband K2 can rotate relative to the first headband K1 within a predetermined angle range set between each rotation range restricting stopper 6. In the case of this double movable headband K, this predetermined angle is generally set to the angle between the top of the head and the bangs.

[0033] Figure 4 shows an example of the use of the double movable headband K connected by this connection unit U1, in this case an example of the use of the double movable headband K when the user puts on a hat. Figure 5 shows the operation of the connection unit U1 when using the headband K. As shown in Figures 4 and 5, when using this double movable headband K, first, with the second headband K2 closed relative to the first headband K1, the fixing parts 2,2 of the first headband K1 are fixed to both sides of the head near the upper back of both ears, the hair holding part 1 is placed across the top of the head, and the hair near the top of the head is passed through the coil-shaped hair holding parts 10 of the hair holding part 1 and fixed tightly to the scalp. Next, the second headband K2 is opened relative to the first headband K1 toward the front of the head. In this case, when the second headband K2 is opened toward the front of the first headband K1, the rotation guide part 5 of the movable connecting part U12 of the second headband K2, in this case the ring-shaped parts 51, 53, are rotated toward the front on the rotation guide part 4 of the fixed connecting part U11 of the first headband K1, in this case the spherical surface of each ball, causing the second headband K2 to rotate toward the front of the first headband K1. When the second headband K2 is opened to its maximum extent in this manner, one straight section 52 of the movable connecting part U12, that is, one of the rotation range restricting stoppers 6, abuts against the rod-shaped bodies of each fixing part 2,2 of the first headband K1, restricting the movement of the second headband K2 in the opening direction, and the second headband K2 is positioned and placed over the forehead (around the bangs). Then, similar to the first headband K1, the bangs are passed through each coil-shaped hair holding part 10 of the hair holding part 1 and fixed tightly to the scalp.

[0034] When the double movable headband K is attached to two locations on the head and a hat is worn, the pressure on the hair from the hat can be suppressed at least two locations on the top and forehead. Furthermore, since the hair-holding parts 10, 10 of each headband K1, K2 are coil-shaped with a predetermined pitch, the hair, including the roots of the hair at the locations where each headband K1, K2 is fixed, enters the coil, suppressing the crushing of the hair in those areas by the pressure of the hat. As a result, crushing of the hair near the roots, at least in the bangs and on the top of the head, is suppressed, and noticeable disturbance of the hairstyle due to wearing a hat is prevented. Thus, this double movable headband K can be easily attached to the head when wearing a hat, reliably suppresses the crushing of the hair in the bangs and on the top of the head while wearing a hat, prevents the hairstyle from becoming messy after wearing a hat, and allows for easy styling of the hairstyle.

[0035] Furthermore, when not in use, the two movable headbands K1 and K2 can be folded compactly by closing them. In this case, even if the headbands K1 and K2 are closed somewhat roughly, the other straight part 54 of the movable connecting part U12 of the second headband K2, that is, the other rotation range restricting stopper 6, abuts against the rod-shaped bodies of the fixed parts 2,2 of the first headband K1, restricting the movement of the second headband K2 in the closing direction. As a result, the headbands K1 and K2 do not come into strong contact with each other, preventing damage from strong impacts between the headbands K1 and K2. By folding the headbands K compactly when not in use in this way, they can be stored without taking up much space or getting in the way, whether placed on a dressing table, stored in a drawer, or carried in a bag when going out.

[0036] As explained above, with this connection unit U1, the headbands K1 and K2 are connected by combining the fixed-side connection part U11 and the movable-side connection part U12 between them. Therefore, two, three, or more headbands can be easily connected, and it can be used in common with various types of headbands. It is cost-effective and provides an optimal connection unit for connecting many different types of headbands.

[0037] In particular, in this connection unit U1, the fixed connection part U11 is made of a sphere, and this sphere is provided on each of the fixed parts 2,2 of the first headband K1, while the other side is made of an oval or rectangular frame-shaped member that exhibits an arc shape along the spherical surface of the sphere, and this arc-shaped frame member is provided on each of the fixed parts 2,2 of the second headband K2, and the arc-shaped frame member is connected so that each of the fixed parts 2,2 of the first headband K1 is passed through its frame and it can rotate along the sphere, so that the two coil-type headbands K1 and K2 can be connected simply and reliably, and the manufacturing cost can be kept low.

[0038] Furthermore, in this connection unit U1, there is a rotation range restricting stopper 6 between the rotation guide portion 4 of the fixed connection part U11 and the rotation guide portion 5 of the movable connection part U12, which restricts the rotation range of the movable connection part U12 relative to the fixed connection part U11. Therefore, when using the headband K, as described above, when the second headband K2 is opened to its maximum extent, the rotation range restricting stopper 6 on one side positions the second headband K2 roughly at the front of the head (around the bangs). When not in use, the headbands K1 and K2 can be folded compactly by closing them, and at that time, the rotation range restricting stopper 6 on the other side prevents strong impacts between the headbands K1 and K2, thereby preventing damage to the headbands K1 and K2.

[0039] Figure 6 shows the connection unit U2 as a second embodiment. Note that Figures 6(a) and (b) differ only in how the headbands K1 and K2 of the connection unit U2 are attached to the fixing part 2; the structure of the connection unit U2 itself is the same.

[0040] As shown in Figure 6, the connection unit U2 comprises a fixed-side connection part U21 provided on each fixed part 2 of one headband K1 (or K2) and having a rotating guide portion having a circular or arc-shaped cross-section, and a movable-side connection part U22 provided on the fixed part 2 of the other headband K2 (or K1) and having a rotating guide portion having a circular or arc-shaped cross-section that can rotatably engage on the rotating guide portion of the fixed-side connection part U21. The connection unit U2 also includes a rotation range restricting stopper between the rotating guide portion of the fixed-side connection part U21 and the rotating guide portion of the movable-side connection part U22, which restricts the rotation range of the movable-side connection part U22 relative to the fixed-side connection part U21. Furthermore, this connection unit U2 also includes a plurality of rotation position stoppers between the rotation guide portion of the fixed-side connection part U21 and the rotation guide portion of the movable-side connection part U22, which stop the rotation of the movable-side connection part U22 relative to the fixed-side connection part U21 at predetermined small angle intervals.

[0041] In this case, the fixed connecting part U21 is made of synthetic resin and consists of a roughly cap-shaped cylindrical structure, and this cylindrical structure is provided at each fixing part 2,2 of the First Katyusha K1. This cylindrical structure is a so-called general circular cap shape and has a circular part 211 and a shorter cylindrical part (outer cylindrical part) 212 that extends slightly from the entire peripheral edge of one side of the circular part 211. A further cylindrical part (inner cylindrical part) or intermittent cylindrical part (an inner part formed by dividing the cylindrical part via one or more notches) is formed inside the outer cylindrical part 212, and these outer cylindrical part and inner cylindrical part or intermittent cylindrical part constitute a rotating guide part with a circular or arc-shaped cross-section.

[0042] In this case, as part of a rotation range restricting stopper, a convex portion is formed on at least one arbitrary location on the inner surface of the outer cylindrical portion or on the outer surface of the inner cylindrical portion or intermittent cylindrical portion, or at any two locations spaced apart according to the rotation angle of the second headband K2 relative to the first headband K1, such that the convex portion is convex in the inner direction in the case of the inner surface of the outer cylindrical portion, and convex in the outer direction in the case of the outer surface of the inner cylindrical portion or intermittent cylindrical portion, with the convex portion extending perpendicular to the circumferential direction.

[0043] Furthermore, in this case, a small protrusion or recess is formed as part of the rotation position stopper at any one location or any predetermined angular range (an angular range corresponding to the rotation angle of the second headband K2 relative to the first headband K1) on the inner surface of the outer cylindrical portion or the outer surface of the inner cylindrical portion or the intermittent cylindrical portion. In the case of one location, one small protrusion or recess is formed, and in the case of a predetermined angular range, multiple small protrusions or recesses are formed continuously in the circumferential direction.

[0044] In order to connect the fixed-side connecting part U21 and the movable-side connecting part U22, at least one of the inner surface of the outer circumferential cylindrical part or the outer surface of the inner circumferential cylindrical part or intermittent cylindrical part is formed continuously or intermittently in the circumferential direction, either as a convex portion that is convex in the inward direction or a concave portion that is concave in the outward direction, or as a convex portion that is convex in the outward direction or a concave portion that is concave in the inward direction, either as a convex portion that is convex in the outward direction or a concave portion that is concave in the inward direction, for the purpose of connecting the two.

[0045] In this way, as shown in Figure 6(a), the fixing part U21 on the fixed side is inserted and fixed to the fixing part 2 of the first headband K1 by the outer cylindrical part 212. Alternatively, as shown in Figure 6(b), a mounting part for the fixing part 2 may be provided on the outer surface of the circular part 211 of the fixing part U21, and the fixing part 2 of the first headband K1 may be attached to this mounting part.

[0046] In contrast, the movable connecting part U22 is made of synthetic resin and consists of a roughly cap-shaped cylindrical structure having a cylindrical portion so that it can be fitted into the inner circumference of the cylindrical structure of the fixed connecting part U21 so that it can rotate on the inner circumference of the cylindrical structure of the fixed connecting part U21, and this cylindrical structure is provided at each fixed part 2 of the second headband K2. This cylindrical structure is a circular cap shape similar to the fixed connecting part U21 and has a circular portion 221 and a shorter cylindrical portion (outer cylindrical portion) 222 that extends slightly from the entire peripheral edge of one side of the circular portion 221. Inside the outer cylindrical portion 222, a cylindrical portion (inner cylindrical portion) or an intermittent cylindrical portion (an inner cylindrical portion formed by dividing the cylindrical portion through one or more notches) is formed protruding from the outer cylindrical portion 222 so that it can be fitted and arranged along the rotation guide portion of the fixed connecting part U21, and this inner cylindrical portion or intermittent cylindrical portion constitutes a rotation guide portion with a circular or arc-shaped cross-section.

[0047] In this case, in contrast to the fixed connecting part U21, the remaining part of the rotation range restricting stopper is formed at any two locations or any one location on the outer surface of the inner cylindrical portion or intermittent cylindrical portion, or on the inner surface of the inner cylindrical portion or intermittent cylindrical portion, that are spaced apart according to the rotation angle of the second headband K2 relative to the first headband K1. In the case of the outer surface of the inner cylindrical portion or intermittent cylindrical portion, the convex portion is formed in the outer direction, and in the case of the inner surface of the inner cylindrical portion or intermittent cylindrical portion, the convex portion is formed in the inner direction, with the convex portion extending perpendicular to the circumferential direction.

[0048] Furthermore, in this case, in contrast to the fixed connecting part U21, at least one of the outer circumferential surface of the inner cylindrical portion or the intermittent cylindrical portion, or the inner circumferential surface of the inner cylindrical portion or the intermittent cylindrical portion, is formed as the remaining part of the rotation position stopper. This includes multiple small recesses or protrusions arranged continuously in the circumferential direction within the predetermined angle range, or one small recess or protrusion if it is at one location. These protrusions are formed within an arbitrary predetermined angle range (an angle range corresponding to the rotation angle of the second headband K2 relative to the first headband K1) or at an arbitrary single location.

[0049] In order to connect the movable connecting part U22 and the fixed connecting part U21, at least one of the outer or inner circumferential surfaces of the inner cylindrical portion or intermittent cylindrical portion is formed continuously or intermittently in the circumferential direction, in the case of the outer circumferential surface of the inner cylindrical portion or intermittent cylindrical portion, and in the case of the inner circumferential surface of the inner cylindrical portion or intermittent cylindrical portion, a concave portion that is concave in the circumferential direction or a convex portion that is convex in the circumferential direction is formed continuously or intermittently in the circumferential direction.

[0050] In this way, the movable connecting part U22 is attached to the fixing part 2 of the second headband by inserting and fixing the fixing part 2 of the second headband K2 through the outer cylindrical part, as shown in Figures 6(a) and (b).

[0051] In this way, the connecting parts U21 and U22 are configured, and the connecting unit U2 is formed by combining the connecting parts U21 and U22 so that they can rotate with each other. In this case, when a part of the movable connecting part U22, i.e., the rotation guide part (inner cylindrical part or intermittent cylindrical part), is fitted into the rotation guide part (between the outer cylindrical part and the inner cylindrical part) of the fixed connecting part U21, it is prevented from coming apart by the engagement of the convex and concave parts for coupling between the fixed and movable connecting parts U21 and U22, and the rotational guidance of the rotation guide part between them allows the connecting parts U21 and U22 to rotate with each other. In conjunction with this assembly, a rotation range restricting stopper is formed by a portion and the remainder of the rotation range restricting stopper between the two connecting parts U21 and U22, that is, one protrusion on one of the two is positioned between two protrusions on the other, and a rotation position stopper is formed by a portion and the remainder of the rotation position stopper between the two connecting parts U21 and U22, that is, one small protrusion or small recess on one of the two engages with one of the multiple small recesses or small protrusions on the other. The rotation range restricting stopper, that is, the engagement between one protrusion on one of the fixed connecting part U21 or the movable connecting part U22 and two protrusions on the other, allows the movable connecting part U22 to rotate within a predetermined range of rotation angle relative to the fixed connecting part U21. The rotation position stopper, that is, the engagement (interlocking) of one small protrusion or recess on either the fixed-side connecting part U21 or the movable-side connecting part U22 with multiple small recesses or protrusions on the other, allows the movable-side connecting part U22 to rotate in small increments relative to the fixed-side connecting part U21.

[0052] This method also produces the same effects and advantages as the first embodiment.

[0053] In the first and second embodiments, the example shown was the connection of two headbands using the connecting unit. However, even with three or more headbands, the same method can be used to connect them as a multi-unit movable system by attaching the fixed-side connecting parts to the fixed parts of one headband and the movable-side connecting parts to the fixed parts of the other headband, and then joining the connecting parts together. In this way, even with a multi-unit movable headband of three or more units, the same effects and advantages as described above can be achieved by using the connecting unit.

[0054] In the first and second embodiments, the multi-unit movable headbands were exemplified in which each headband as a whole exhibits a roughly C-shape, and the hairstyle-holding portion is formed in a coil shape to lift and hold the hair away from the scalp. However, each headband may be roughly U-shaped as a whole, or the hairstyle-holding portion may be formed in a curved shape such as a wave shape (e.g., wave, sawtooth, comb shape) to lift or float the hair away from the scalp. Furthermore, although each headband was made of a metal material, it may also be made of a synthetic resin material. In this way, the headbands can be connected as a multi-unit movable headband by attaching the fixed-side connecting parts to each fixed part of one headband and the movable-side connecting parts to each fixed part of the other headband, and then joining the connecting parts. Thus, even with a wide variety of forms of multi-unit movable headbands, the same effects as described above can be achieved by using the connecting unit.

[0055] In the second embodiment, the fixed and movable connecting parts are formed in a substantially cap shape of the same size, and the movable connecting part has an inner cylindrical portion or an intermittent cylindrical portion, which is fitted between the outer cylindrical portion and the inner cylindrical portion of the fixed connecting part. Alternatively, the fixed connecting part may be formed in a substantially cap shape consisting only of a circular portion and an (outer) cylindrical portion, and the movable connecting part may have substantially the same configuration as in the second embodiment, with the inner cylindrical portion or intermittent cylindrical portion being formed to be slightly smaller in diameter than the inner diameter of the (outer) cylindrical portion of the fixed connecting part, and fitted into the (outer) cylindrical portion of the fixed connecting part so as to be frictionally engaged, and the rotation guide portion of the movable connecting part may be able to stop at any rotational position by frictional engagement with the rotation guide portion of the fixed connecting part. In this case, the movable connecting part may be formed as a coin-shaped cylinder that can be frictionally engaged with the cylindrical portion (outer circumference) of the fixed connecting part, instead of being cap-shaped, and a mounting portion for the fixed part of the second headband may be formed as a convex shape on one of its outer surfaces, so that the coin-shaped movable connecting part is fitted into the cap-shaped fixed connecting part. In this way, the rotation guide portion of the movable connecting part may be frictionally engaged with the rotation guide portion of the fixed connecting part so that it can be stopped at any rotational position. This method can achieve the same effects as described above, and the overall structure can be simplified, further reducing costs.

[0056] In the second embodiment, the rotation guide portion, rotation range restricting stopper, and rotation position stopper of the fixed-side and movable-side connecting parts are shown as examples, and these parts can be modified in various ways as long as they have the same function as shown in this example.

[0057] In the second embodiment, the fixed and movable connecting parts are formed in the shape of circular caps. However, since the engagement surfaces of each connecting part only need to have a circular or arc-shaped cross-section, the outer cylindrical portion may be angular, such as a triangle or square, and various decorative designs may be applied. This increases the variations of the connecting unit.

[0058] Next, specific examples 1 and 2 of the second embodiment are shown in Figures 7 and 8.

[0059] As shown in Figure 7, the connection unit U2-1 of Specific Example 1 comprises a fixed-side connection part U21-1 provided on each fixed part 2 of one headband K1 (or K2) and having a rotating guide part 4 having a circular or arc-shaped cross-section, and a movable-side connection part U22-1 provided on the fixed part 2 of the other headband K2 (or K1) and having a rotating guide part 5 having a circular or arc-shaped cross-section that can rotatably engage on the rotating guide part 4 of the fixed-side connection part U21-1. This connection unit U2-1 also has a rotation range restricting stopper 6 between the rotating guide part 4 of the fixed-side connection part U21-1 and the rotating guide part 5 of the movable-side connection part U22-1 that restricts the rotation range of the movable-side connection part U22-1 relative to the fixed-side connection part U21-1.

[0060] In this case, the fixed-side connecting part U21-1 is made of synthetic resin and consists of a roughly cap-shaped cylindrical structure, and this cylindrical structure is provided at each fixing part 2,2 of the first headband K1 (see Figure 6). This cylindrical structure is a so-called general circular cap shape and has a circular part 211-1 and a shorter cylindrical part (outer cylindrical part) 212-1 that extends slightly from the entire peripheral edge of one side of the circular part 211-1, and the inner circumferential surface 40 of the outer cylindrical part 212-1 constitutes a part of the rotating guide part 4 which has a circular cross-section.

[0061] In this case, a concave portion 41 is continuously formed in the circumferential direction on the inner circumferential surface 40 of the outer cylindrical portion 212-1, for the purpose of connecting the fixed-side connecting part U21-1 and the movable-side connecting part U22-1, and as part of the remaining portion of the rotation guide 4 and the rotation range restricting stopper 6. In this case, the concave portion 41 is continuously formed on the inner circumferential surface 40 of the outer cylindrical portion 212-1 up to a predetermined angle (in this case, a range greater than half the circumference of the inner circumferential surface 40 but less than the entire circumference) set considering the rotation angle of the movable-side connecting part U22-1. Thus, the entire concave portion 41 is the remaining portion of the rotation guide 4, and both ends of the concave portion 41 form part of the rotation range restricting stopper 6.

[0062] In this way, as shown in Figure 6(a), the fixing part U21-1 on the fixed side is inserted and fixed to the fixing part 2 of the first headband K1 through the outer cylindrical part 212-1, and is attached to the fixing part 2 of the first headband K1. Alternatively, as shown in Figure 6(b), a mounting part for the fixing part 2 may be provided on the outer surface of the circular part 211-1 of the fixed side connecting part U21-1, and the fixing part 2 of the first headband K1 may be attached to this mounting part.

[0063] In contrast, the movable connecting part U22-1 is made of synthetic resin and consists of a roughly cap-shaped cylindrical structure having an inner cylindrical portion 223 in part, with a portion of it rotatably fitted onto the inner circumferential surface 40 of the cylindrical structure of the fixed connecting part U21-1. This cylindrical structure is provided on each fixed portion 2,2 of the second headband K2. This cylindrical structure is a circular cap shape similar to the fixed connecting part U21-1 and has a circular portion 221-1 and a shorter cylindrical portion (outer cylindrical portion) 222-1 that extends slightly from the entire periphery of one side of the circular portion 221-1. An inner cylindrical portion 223 is formed protruding from the outer cylindrical portion 222-1 so as to be fitted and positioned along the inner circumferential surface 40 of the fixed connecting part U21-1, and the outer circumferential surface 50 of this inner cylindrical portion 223 constitutes a part of the rotating guide portion 5 with a circular cross-section.

[0064] In this case, in order to connect the movable connecting part U22-1 and the fixed connecting part U21-1, a convex portion 51 is continuously formed in the circumferential direction on the outer surface 50 of the inner cylindrical portion 223, opposite to that of the fixed connecting part U21-1, for the purpose of connecting the two, and as the remainder of the rotation guide portion 5 and the remainder of the rotation range restricting stopper 6. In this case, the convex portion 51 is set on the outer surface 50 of the inner cylindrical portion 223, taking into consideration the rotation angle of the movable connecting part U22-1, and is continuously formed up to a predetermined angle smaller than the concave portion 41 of the fixed connecting part U21-1 (in this case, a range of less than half the circumference of the outer surface 50). Thus, the entire convex portion 51 is the remainder of the rotation guide portion 5, and both ends of this convex portion 51 form the remainder of the rotation range restricting stopper 6.

[0065] In this way, as shown in Figures 6(a) and (b), the movable connecting part U22 is attached to the fixing part 2 of the second headband K2 by inserting and fixing the fixing part 2 of the second headband K2 into the outer cylindrical part 222-1.

[0066] In this way, each connecting part U21-1 and U22-1 is constructed, and the connecting unit U2-1 is formed by combining each connecting part U21-1 and U22-1 so that they can rotate relative to each other. In this case, when a part of the movable connecting part U22-1, i.e., the inner circumferential cylindrical portion 223, is fitted into the outer circumferential cylindrical portion 212-1 of the fixed connecting part U21-1, it is prevented from coming loose by the engagement of the concave portion 41 and convex portion 51 for coupling between the fixed and movable connecting parts U21-1 and U22-1, respectively, and the rotation guide portions 4 and 5 between them (the inner circumferential surface 40 and concave portion 41 of the outer circumferential cylindrical portion 212-1 of the fixed connecting part U21-1, and the movable connecting portion) The connecting parts U21-1 and U22-1 are assembled so that they can rotate relative to each other by rotational guides of the outer surface 50 and convex portion 51 of the inner cylindrical portion 223 of connecting part U22-1, and the rotational range restricting stoppers 6 between them (one end of the concave portion 41 of the fixed connecting part U21-1 and one end of the convex portion 51 of the movable connecting part U22-1) are in contact to restrict the rotational range between the connecting parts U21-1 and U22-1 to a predetermined angle. The rotational guides 4 and 5 allow the movable connecting part U22-1 to rotate relative to the fixed connecting part U21-1, and the rotational range restricting stoppers 6 allow the movable connecting part U22-1 to rotate relative to the fixed connecting part U21-1 within a predetermined rotational angle range. Even in this manner, the same effects and advantages as in the first embodiment can be achieved.

[0067] As shown in Figure 8, the connection unit U2-2 of Specific Example 2 basically has the same configuration as the connection unit U2-1 of Specific Example 1. Here, the same reference numerals are used for the components that are common to the connection unit U2-1 of Specific Example 1, and redundant explanations are omitted. The connection unit U2-2 differs from the connection unit U2-1 in that it also has multiple rotation position stoppers 7 between the rotation guide portion 4 of the fixed-side connection part U21-2 and the rotation guide portion 5 of the movable-side connection part U22-2, which stop the rotation of the movable-side connection part U22-2 relative to the fixed-side connection part U21-2 at predetermined small angle intervals. Here, only this difference is given a different reference numeral and an additional explanation is provided.

[0068] In this case, a plurality of small recesses 410 are provided as part of the rotation position stopper 7 on the back surface (bottom surface) of the recessed portion 41 provided on the inner circumferential surface 40 of the outer cylindrical portion 212-1 of the fixed connecting part U21-2, at arbitrary angles within an arbitrary predetermined angular range, that is, at predetermined angles considering the stepwise rotation angles of the second headband K2 relative to the first headband K1 throughout the entire area of ​​the recessed portion 41. Here, the small recesses 410 are formed in a hemispherical shape.

[0069] In this case, a small protrusion 511 is also provided on the top surface of the convex portion 51 on the outer circumferential surface 50 of the inner cylindrical portion 223 of the movable connecting part U22-2, so as the remainder of the rotation position stopper 7, it can engage with each small recess 410 of the concave portion 41 of the fixed connecting part U21-2 at any predetermined angle intervals within an arbitrary predetermined angle range, that is, at predetermined angles considering the stepwise rotation angles of the second headband K2 relative to the first headband K1. Here, the small protrusion 511 is formed in a hemispherical shape so as to be able to fit into each small recess 410, with one small protrusion 511 on one end of the top surface of the convex portion 51.

[0070] In this way, the connecting parts U21-2 and U22-2 are configured, and the connecting unit U2-2 is formed by combining the connecting parts U21-2 and U22-2, similar to the connecting unit U2-1 in specific example 1, so that they can rotate relative to each other. In this case, one small protrusion 511 on one of the two parts engages with one of the multiple small recesses 410 on the other part to form a rotation position stopper 7. The rotation position stopper 7 allows the movable connecting part U22-2 to rotate and stop in small increments relative to the fixed connecting part U21-2. Even in this manner, the same effects and advantages as in the first embodiment can be achieved.

[0071] Figures 9, 10, and 11 show the connection unit U3 as a third embodiment. Figures 9 and 10 show the overall configuration of the connection unit U3 for the multi-movable headband, and Figure 11 shows the configuration of its main parts. In this embodiment as well, the configuration of the multi-movable headband K itself (excluding the connection unit U3 for the multi-movable headband) is the same as in the first embodiment, so here, the same reference numerals as in the first embodiment are used for the common components, and redundant explanations are omitted.

[0072] As shown in Figures 9 and 10, the multi-movable headband connection unit U3 (hereinafter simply referred to as connection unit U3) comprises a fixed-side connection part U31 provided on each fixed part 2,2 of one headband K1 (or K2) and having a rotating guide part 4 with a circular cross-section, and a movable-side connection part U32 provided on each fixed part 2,2 of the other headband K2 (or K1) and having a rotating guide part 5 with a circular or arc-shaped cross-section that can rotatably engage on the rotating guide part 4 of the fixed-side connection part U31. In addition, this connection unit U3 also has a rotation range restricting stopper 6 (see Figure 11) between the rotating guide part 4 of the fixed-side connection part U31 and the rotating guide part 5 of the movable-side connection part U32 that restricts the rotation range of the movable-side connection part U32 relative to the fixed-side connection part U31.

[0073] This connection unit U3 consists of either the fixed-side connection part U31 or the movable-side connection part U32, as shown in Figure 11(a), a support shaft 43 having a guide surface 431 with an arc-shaped cross-section on at least a part of its outer circumferential surface, and a locking part 44 protruding from the tip of the support shaft 43 in a direction intersecting (in this case, approximately perpendicular) to the axis of the support shaft 43. The support shaft 43 and the locking part 44 are provided on each of the fixed parts 2,2 of one of the headbands K1 (or K2), and the other is as shown in Figure 11(b). As shown, it consists of an annular member 53 having an arc-shaped guide portion 530 on at least a part of its inner circumference, and the annular member 53 is provided on each fixing portion 2,2 of the other headband K2 (or K1), and as shown in Figure 11(c), the support shafts 43 of each fixing portion 2,2 of the one headband K1 (or K2) are passed through the annular part of the annular member 53 and are prevented from coming off by a locking portion 44, and are rotatably connected by the engagement guidance of the guide surface 431 and the guide portion 530 between them.

[0074] Thus, the fixed-side connecting part U31 consists of a support shaft 43 and a locking part 44 at its tip. Here, each fixing part 2,2 is made of a wire with a circular cross-section and is roughly rod-shaped, so the support shaft 43 and the locking part 44 are formed by using this wire and bending a part of each fixing part 2,2 near the upper end. As shown in Figure 11(a), the fixed-side connecting part U31 is formed by bending a part of each fixing part 2,2 into a roughly T-shape. In this case, the upper end of each fixing part 2,2 is a vertical linear axis 21 that extends linearly downward in the vertical direction, and the portion directly below this vertical linear axis 21 at the upper end is bent outward in a roughly U shape (in the opposite direction from the other fixing part 2,2 in each fixing part 2,2) and protruding outward as a roughly U-shaped short axis 31, a roughly straight short axis 33 that extends linearly downward in the vertical direction via a roughly inverted U-shaped folding axis 32 from the roughly U-shaped short axis 31, and a roughly inverted U-shaped short axis 35 that returns inward (towards the fixing part 2) in a roughly inverted U shape via a roughly U-shaped folding axis 34 from the roughly straight short axis 33, and the fixing side connecting part U31 is formed by this bending process. In other words, the roughly U-shaped short axis 31 and the roughly inverted U-shaped short axis 35 form the support shaft 43, and due to the circular cross-section of each short axis 43, the outer surfaces of each short axis 31 and 35 form a guide surface 431 with a circular cross-section. The roughly inverted U-shaped folding shaft 32, the roughly straight short axis 33, and the roughly U-shaped folding shaft 34 at the tips of these short axes 31 and 35 form the locking portion 44. The portion below the fixed-side connecting part U31 is a vertical linear axis 22 that extends linearly downward in the vertical direction on the lower side of each fixed portion 2.

[0075] Furthermore, the movable connecting part U32 consists of an annular member 53. Here, the annular member 53 is also formed by bending each of the fixed parts 2,2. As shown in Figure 11(b), it is formed by shortening and deforming the entire fixed parts 2,2. In this case, each fixed part 2,2 is shortened to the length required for the annular member 53 and bent into a roughly annular shape, with the tip folded back to the upper end of each fixed part 2,2, and the movable connecting part U32 is formed by this bending process. The inner circumference of the annular member 53 forms a guide part 530 with a circular cross-section.

[0076] In this fixed part U31 and movable part U32, as shown in Figure 11(c), when the two are assembled, the tip of the annular member 53 of the movable part U32 can abut the approximately U-shaped short axis 31 of the fixed part U31 to the approximately inverted U-shaped folding axis 32, and this constitutes the rotation range stopper 6.

[0077] In this way, the first headband K1 and the second headband K2 are connected by combining the fixed-side connecting part U31 and the movable-side connecting part U32. As shown in Figure 9, in this case, each annular member 53 of the second headband K2 has each support shaft 43 of the first headband K1 passed through its annular shape and is secured by each locking part 44, and the guide part 530 (see Figure 11) on the inner circumference of each annular member 53 is guided to rotate on the guide surface 431 (see Figure 11) on the outer circumference of each support shaft 43, thereby allowing the movable-side connecting part U32 to rotatably connect to the fixed-side connecting part U31. Thus, the first headband K1 and the second headband K2 are assembled so that the second headband K2 can rotatably connect to the first headband K1.

[0078] This method also produces the same effects as the first embodiment. Furthermore, in this case, since the fixed and movable parts U31 and U32 are integrally formed using part or all of the fixed parts 2,2 of the first headband K1 and second headband K2, the number of parts can be reduced, the design can be simplified, and costs can be reduced.

[0079] In this embodiment, the fixed connecting part U31 is exemplified as having a locking portion 44 at the tip of the support shaft 43, but it may also be configured to protrude from a part of the outer surface of the support shaft 43 in a direction perpendicular to the axis of the support shaft 43. This allows for the attachment of decorative items to the tip of the support shaft 43.

[0080] Furthermore, in this embodiment, the fixed and movable connecting parts U31 and U32 are exemplified as being integrally formed using part or all of the fixed parts 2, 2 of the first headband K1 and second headband K2, respectively. However, the fixed and movable connecting parts U31 and U32 may be formed separately from the fixed parts 2, 2 and attached to the fixed parts 2, 2 to connect them. In this case, all or part of the support shaft, locking part, and annular member may be formed as separate parts from synthetic resin, metal, wood, etc. This method also produces the same effects as the above embodiment. Furthermore, by applying an aesthetic design to the fixed and movable connecting parts U31 and U32 in this way, the aesthetics and taste of the fixed and movable connecting parts U31 and U32 can be improved.
