Description

[Technical field]

[0001] The present invention relates to an armband used for traffic control, security, etc. at construction sites, event venues, etc. [Background technology]

[0002] Armbands are used to indicate the wearer's status or position when working, such as to show that they are a safety manager or supervising engineer at a construction site, or a security guard at a security site.

[0003] One example of armband-related technology is the "armband" proposed in Patent Document 1. Patent Document 1 describes an armband that has hook and loop tapes that engage with each other on overlapping connecting surfaces at both left and right ends, is connected in a ring shape by engaging members, and can be freely wound around the arm, and that is composed of an armband body with band loops on its inner circumferential surface that are provided at a predetermined interval on the left and right, and a fastening band that is supported by the band loops and provided on the inner circumferential surface of the armband body.

[0004] Also, an "armband" is proposed in Patent Document 2. Patent Document 2 describes an armband that includes a sheet-like main body member having a display unit on the front side for displaying transmitted information, and a substantially belt-like band member that is detachably attached to the main body member, the main body member having band insertion holes penetrating in the thickness direction on the left and right sides, the band member including a stretchable band main body portion, an engagement member provided on one end side of the band main body portion and removably fixing one end side of the band main body portion to one of the holes of the band insertion hole, and an engagement member attached to the other end side of the band main body portion and fastening the one end side of the band main body portion to one of the holes of the band insertion hole. The document describes an armband that has a locking portion that is inserted into the other hole of the band insertion hole and that is removably fixed to the band main body by adjusting the tightness of the band main body, and that fixes one end of the band main body to one of the band insertion holes with the engaging member and that can be inserted into the other hole of the band insertion hole to form the main body member and the band member into a ring-shaped configuration, and that when the ring-shaped armband is passed over the arm, the locking portion prevents it from slipping out of the other hole of the band insertion hole through which it has been inserted. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2010-19928 A [Patent Document 2] JP 2017-122789 A Summary of the Invention [Problem to be solved by the invention]

[0006] With the "armband" described in Patent Document 1, if you put your arm through the band and tighten it before trying to adjust it, unless you hold down the tip of the band (the loop tape) while tightening it, it will come off the connecting ring, and you will have to remove your arm, reconnect it to the connecting ring, and then try putting it on again.

[0007] The present invention has been devised to solve such problems. That is, an object of the present invention is to provide an armband that can be easily put on by a user with one hand and that is difficult to slip off. [Means for solving the problem]

[0008] The armband comprises a plate-like main body (10) having an information display area for displaying information on the front surface, a resin non-slip surface (115) on the back surface, and holes (22, 23) on the left and right, and a stretchable band (51) that is passed through the holes and detachably attached to the main body.

[0009] The anti-slip member may be formed of a triangular pyramid-shaped protruding member.

[0010] The anti-slip member may be formed in a substantially quarter-sphere shape having a hollow interior.

[0011] The band may have a length-adjustable wire (126) within it, a fastening part (128) for looping the wire around one side of the main body, and a dial (127) for winding the wire around the other side, so that the length of the wire can be adjusted by using the dial.

[0012] The main body may also have cutouts (117, 118). Effect of the Invention

[0013] With the armband of the present invention, when the arm is inserted into the looped armband, the locking part prevents it from slipping out of the band insertion hole, so it can be easily moved to the desired position with one hand. After moving it, the locking part can be easily pulled with one hand to adjust the tightness of the band body and secure it to the band body.

[0014] The resin anti-slip coating on the main body and band makes it less likely to slip off than with conventional products. Also, the two-piece band makes it less likely to come off than a single-piece band. It is equipped with a wire and a dial, and by adjusting the length of the wire, it can be tightened more firmly than conventional products. The cutout portion prevents interference with the pen holder and makes it less likely to come off. [Brief description of the drawings]

[0016] <Overview> An embodiment of the armband of the present invention will be described with reference to the drawings. FIG. 1 is a front view of an armband 1 in an unfolded state. The armband 1 comprises a main body 10 and a band 50. The main body 10 has a right band insertion hole 22 and a left band insertion hole 23 for passing the band 50. The band 50 is attached to the right band insertion hole 22 (or the left band insertion hole 23).

[0017] <Band> FIG. 2 is a front view of the band 50 in an unfolded state. Band 50 is composed of band portion 51, convex button 53, concave button 54, and fastening portion 60. Band portion 51 is knitted and has elasticity. Fastening portion 60 is made of synthetic resin, and is bonded to band portion 51 by thermocompression bonding. Band portion 51 does not have to be knitted as long as it is made of a stretchable material. Furthermore, fastening portion 60 does not have to be made of resin as long as it is made of a thin, flexible material, and can be connected to band portion 51 by sewing it, for example.

[0018] FIG. 3 is a detailed cross-sectional view showing how the band 50 is attached to the main body 10. As shown in FIG. The band 50 is attached to the main body 10 by passing the band portion 51 through the right band insertion hole 22 (or the left band insertion hole 23) of the main body 10 and fitting the convex button 53 and the concave button 54 together. The main body 10 has a hard film 18 and a soft sheet 19 between the front and back surfaces. This is to prevent the main body 10 from tearing or being torn off when a tensile load is applied to the band insertion holes 22, 23. The order in which the hard film 18 and the soft sheet 19 are layered is not limited to that shown in the figure, and the hard film 18 may be on the front surface side or the back surface side.

[0019] FIG. 4 is a rear view showing how the band 50 is passed through the right band insertion hole 22. FIG. The locking portion 60 is made of a thin material and can be folded as shown in the figure. The maximum length of the right band insertion hole 22 and the left band insertion hole 23 is made narrower than the maximum width of the locking portion 60, so that when the locking portion 60 is folded and passed through, it widens and gets caught, preventing it from slipping out.

[0020] The procedure for attaching the band 50 to the main body 10 is not limited to the above, and the band part 51 can be first passed through the right band insertion hole 22 and the left band insertion hole 23, and then the band can be attached by fitting the convex button 53 and the concave button 54 together. In this case, the band 50 can be attached to the main body 10 without bending the locking part 60.

[0021] FIG. 5 is a rear view showing how the locking portion 60 is attached to the band portion 51. As shown in FIG. The locking portion 60 has a hook portion of a hook-and-loop fastener on one side. The band portion 51 has a loop portion of a hook-and-loop fastener over the entire front surface. In the figure, the hook portion is indicated by a dashed line and the loop portion is indicated by a circle. The hook portion of the locking portion 60 is hooked onto the loop portion of the band portion 51 to attach the locking portion 60 to the band portion 51. By adjusting the attachment position, the diameter of the armband 1 can be changed to suit the thickness of the arm worn on it.

[0022] The band portion 51 may also be provided with a non-slip surface 40 made of resin on the back surface thereof.

[0023] <Modification 1 of Example 1> FIG. 6 is a rear view of an armband with two bands. The number of bands 50 provided for one main body 10 is not limited to one. As shown in the figure, a first band 55 and a second band 56 can be attached to the main body 10 in the same manner as the band 50. By providing two or more bands, even if one band comes off, the main body 10 can be held on the arm, making the armband 1 less likely to fall off. In addition to making the armband 1 less likely to come off, the pressure is dispersed, making it suitable for people who feel a sense of pressure on their arms with only one band. In the embodiment, two bands are provided, but three or more bands may be provided. Also, instead of providing two right band insertion holes 22 and two left band insertion holes 23, one large insertion hole that can accommodate two bands 10 may be provided each.

[0024] <Main body> FIG. 7 is a detailed front view of the main body. The main body 10 displays information by writing characters and figures over the entire front surface thereof. The main body 10 may also be colored in red, yellow, or the like to convey information.

[0025] The main body 10 may also have an attachment hole 25 at the top so that a clip can be attached. By attaching the clip, the armband 1 can be secured to the wearer's clothing by the clip, and the armband 1 will not come off the wearer's arm even if the band 50 becomes loose.

[0026] <Modification 2 of Example 1> FIG. 8 is a detailed front view of the main body with the card holder. The main body 10 can have a transparent card holder 114 on its front surface. By inserting cards displaying information into the card holder 114 and replacing them as appropriate, the information displayed can be changed according to the situation. It is also possible to turn over a card with different information displayed on both sides, or to insert a business card as a card.

[0027] FIG. 9 is a detailed rear view of the main body portion equipped with a non-slip surface. The back surface of the main body 10 is provided with a resin anti-slip material to prevent the armband 1 from slipping off the arm. For example, this is an uneven anti-slip structure or a resin material attached. Such anti-slip materials are arranged in large numbers or over a wide area.

[0028] <Modification 3 of Example 1> FIG. 10 is a detailed side view of the main body portion provided with a triangular pyramidal anti-slip device. A large number of triangular pyramid-shaped anti-slip devices 115 are arranged on the back surface of the main body 10. The triangular pyramid-shaped anti-slip devices 115 have a long triangular shape with the surface that faces downward when worn, and catch on clothing to prevent the device from slipping off.

[0029] <Modification 4 of Example 1> FIG. 11 is a detailed side view of the main body portion provided with anti-slip protrusions. A large number of anti-slip protrusions 116 are arranged on the back surface of the main body 10. The anti-slip protrusions 116 are cylindrical protrusions made of resin, which catch on creases in the clothes to prevent them from slipping off.

[0030] <Modification 5 of Example 1> FIG. 12 is a detailed rear view of the main body with the spherical anti-slip pads. Spherical anti-slip devices 117 may be provided instead of (or in addition to) the triangular pyramid anti-slip devices 115 and the protruding anti-slip devices 116. A soft resin such as polyvinyl chloride is preferable as the material for the spherical anti-slip devices 117. In the embodiment, three anti-slip devices are provided, but the present invention is not limited to this and one, two, four or more anti-slip devices may be provided.

[0031] FIG. 13 is a detailed side view of the body with the spherical cleats. The spherical anti-slip device 117 is a quarter sphere with a hollow inside. To make it easy to wear and difficult to slip off, it is arranged with the spherical surface on the top and the flat surface (semicircular surface) on the bottom. It is made of a soft material, and is put on by squeezing it. It tries to return to a spherical shape due to its elasticity, so that it catches on the wearer's arm.

[0032] <Modification 6 of Example 1> FIG. 14 is a front view of the armband with the dial and wire. The armband 1 may include a wire 126 instead of the band 50. It further includes a dial 127, a clasp 128, and a cover 129. The dial 127 winds up the wire 126 and tightens the armband 1. The hook 128 acts like a pulley and allows the wire 126 to be looped around and slid. The cover 129 covers the wire 126 to prevent it from getting tangled or caught on things. For example, a structure may be adopted in which pressing a switch (not shown) provided on the dial 127 releases the inhibition of the ratchet gear, allowing the dial 127 to rotate freely and loosen the wire 126.

[0033] FIG. 15 is a front view of an armband with wires. Instead of looping the wire 126 around the hook portion 128, the end of the wire 126 may be fixed.

[0034] <Seventh Modification of the First Embodiment> FIG. 16 is a detailed front view of an armband with cutouts. The main body 10 can have an upper cutout 118 and a lower cutout 119. This is because, in work clothes that have a pen holder H on the arm, a pen P inserted in the pen holder H may push the main body 10, which may cause the armband 1 to come off. By having the upper cutout 118 and the lower cutout 119 in the main body 10, the main body 10 will not be pushed and will be less likely to come off. EXAMPLES

[0035] The following description will be given assuming that armband 1 is worn on the left arm. 17 and 18 are diagrams showing armband 1 of Example 2. These diagrams show one end of band 50 (50A) attached to main body 10 that constitutes armband 1, and a bottom view is omitted since it is symmetrical with the plan view. 19 and 20 are diagrams showing the components that make up the armband 1. In FIG. 17, the sewing line 64 (described in detail later) is indicated by a vertical dashed line. In FIG. 19(a), the display unit 15 is indicated by a two-dot chain line, and the center line L is indicated by a one-dot chain line, and as an example, the main body 10 is shown with characters and figures printed on the display unit 15. In FIG. 20(a), hatching is used to indicate the loop surface R and the hook surface F when viewed from the front. In the following explanation, the surface that faces outward when the armband 1 is attached to the arm is referred to as the front surface, and the surface that faces the arm is referred to as the back surface or rear surface, and the left, right, top, and bottom directions are indicated based on the state in which the armband 1 is viewed from the front surface.

[0036] The armband 1 comprises a main body 10 having a display section 15 for displaying information (hereinafter referred to as "communication information") in the form of letters, figures, symbols, patterns, colors, codes, etc., to inform people around, such as that the person is an involved person at the site, and two types of bands 50A and 50B of different lengths that are detachably attached to the main body 10. When wearing the main body 10 on the arm, the user can select an appropriate one of the two types of bands 50A or 50B and attach it to the main body 10 for use. Note that the band 50B is not shown in the drawings.

[0037] The main body 10 of the armband 1 is made of a synthetic resin material, and as shown in FIG. 19 etc., is a substantially rectangular plate-like member formed in line symmetry with respect to a straight line L that passes through the center and extends vertically. The corners of the main body 10 are rounded, and the four sides (lower side 11, right side 12, left side 13, upper side 14) are connected by smooth curves. The center of the front side of the main body 10 is a display section 15 (see FIG. 19(a)) on which communication information is displayed by printing or writing. In other words, the communication information does not necessarily have to be displayed in advance on the display section 15, and the communication information may be conveyed by a difference in color of the main body 10 itself, or written on the display section 15.

[0038] As shown in FIG. 19, the lower side 11 of the main body 10 is a substantially V-shaped curve formed so as to gradually go downward from both ends 11b to the center 11a, and the inclination of the tangent line is formed so as to become gentler from both ends 11b to the center 11a. The upper side 14 of the main body 10 is a V-shaped (wave-shaped) curve consisting of two substantially arc-shaped curved portions 141, 142 that extend downward, and is formed so as to go downward once from both ends 14b to the center 14a and then gradually go upward. In other words, the inclination of the tangent line of the curved portions 141, 142 is formed so as to become gentle from both ends 14b to the center 14a, become horizontal once, and then gradually become steeper. In this way, the main body 10 has a substantially triangular lower protrusion 21 that protrudes downward at its lower part, a substantially triangular upper protrusion 24a that protrudes upward at its upper center, and a substantially triangular upper right protrusion 24b and an upper left protrusion 24c that protrude slightly upward at both ends of its upper part. Furthermore, it is preferable that the main body 10 has a display unit 15 capable of displaying the transmitted information at a size that can be seen, while being compact so as not to get in the way of work. In this embodiment, as an example, the longest vertical part is formed to have a length of 75 mm, and the longest horizontal part is formed to have a length of 145 mm.

[0039] The body 10 of the armband 1 is provided with a right band insertion hole 22, which is a vertically long through hole (long hole) formed approximately parallel to the right side 12 on the right side thereof, through which one end of the band 50 (50A or 50B) is inserted and fixed in a detachable manner. Also provided with a left band insertion hole 23, which is a vertically long through hole (long hole) formed approximately parallel to the left side 13 on the left side thereof, through which the other end of the band 50 is inserted, as will be described in detail later. The band insertion holes 22, 23 (right band insertion hole 22 and left band insertion hole 23) have widths and heights approximately equal to the thicknesses and heights of the strip-shaped bands 50A, 50B (hereinafter referred to as bands 50 as appropriate), respectively, and are sized to allow the band 50 to be inserted into the band insertion holes 22, 23 with a slight margin (1 to 2 mm in this embodiment) so that the inserted band 50 can be easily moved. Therefore, by pulling on the locking portion 60 described later, the longitudinal position of the band 50 relative to the band insertion hole 23 (or band insertion hole 22 when worn on the right arm) can be changed, making it easy to adjust the tightness.

[0040] The upper protrusion 24a of the main body 10 is formed with an attachment hole 25 for attaching a hand clip 80, which is a clip with a safety pin, and as shown in FIG. 21, the hand clip 80 can be detachably attached according to the user's preference. The attachment hole 25 is composed of a straight cut line extending horizontally and round holes at both ends thereof, which makes it easy to attach the hand clip 80 and reduces the risk of damage. When it is not preferable to fasten the band 50, the band 50 can be loosened and the hand clip 80 can be attached to clothing to prevent it from falling off or shifting. The main body 10 to which only the hand clip 80 is attached can also be used as a name tag to be attached to the chest, etc.

[0041] The main body 10 of the armband 1 has a three-layer structure (not shown) and is manufactured by pressing three semi-rigid sheet-like members 101, 102, and 103 made of synthetic resin material. In this embodiment, for example, the sheet-like members 101, 102, and 103 made of vinyl chloride resin having approximately the same components are firmly welded using an ultrasonic welder and are also melt-cut to a predetermined shape (see FIG. 19). The thickness is, for example, 1.0 to 2.0 mm, and in this embodiment, it is approximately 1.2 mm.

[0042] The front sheet-like member 101 shown in Fig. 19(a) is colored in various desired colors by kneading in coloring agents and is matte-finished, and information to be communicated can be printed or written on the display section 15 on the front side. The back sheet-like member 103 shown in Fig. 19(b) is made of a non-slip material with fine irregularities 10a formed on the back side to provide an anti-slip function. In this embodiment, the irregularities 10a are formed using the irregularities of cloth, and by making the shape similar to the irregularities of the fabric of clothing, the friction coefficient is increased, providing a more effective anti-slip function.

[0043] The front sheet-like member 101 and the back sheet-like member 103 are welded and cut by sandwiching a middle sheet-like member 102 (see FIG. 19(b)) made of vinyl chloride resin between them as a core material for reinforcing them. With this configuration, even if the band 50 is stretched when worn, there is almost no risk that the display unit 15 will wrinkle and the transmitted information will not be visible, or that the main body unit 10 will break and be destroyed. In addition, since the main body unit 50 is semi-rigid and has appropriate flexibility, it deforms to fit the shape of the part to be worn (arm or clothing) when worn. Note that, instead of providing the middle sheet-like member 102, the front sheet-like member 101 and / or the back sheet-like member 103 may be thickened to form the main body unit 10 into a two-layer structure. The main body unit 10 may also be a single sheet-like member that is processed to have the functions of the front sheet-like member 101 and the back sheet-like member 103.

[0044] Next, the band 50 of the armband 1 will be described. Two types of bands 50 (50A and 50B) of different lengths are provided for the main body 10 so that the band can be attached to the wrist according to the size of the wrist when worn (hereinafter simply referred to as wrist size). Band 50A has a short band portion 51A, while band 50B has a long band portion 51B. Bands 50A and 50B differ only in the length of band portions 51A and 51B (hereinafter appropriately referred to as band portion 51), and therefore band 50B and band portion 51B are not shown in the figures, and similar configurations are denoted by similar reference numerals, etc., to avoid redundant explanations.

[0045] The band 50A of the armband 1 is made of a synthetic fiber material, and as shown in FIG. 20 etc., has a band-shaped band portion 51A made of an elastic material such as stretchable rubber, and a generally rectangular fastening portion 60 that is detachably fastened to the band portion 51A. The band portion 51 is a hook-and-loop fastener loop tape, and the entire front surface side is a loop surface (pile fabric) R (the back surface side is not a loop surface). Also, one end side (the left side in FIG. 20(a) ; hereinafter, referred to as the base end side as appropriate) is provided with a convex button 53 and a concave button 54 that engage with each other. In this embodiment, the convex button 53 and the concave button 54 are a pair of hook buttons 53, 54 made of synthetic resin, and are attached so that their respective engagement portions 53a, 54a (see FIG. 20(b)) face the back surface side. The fastening portion 60 is made of a hook tape of a hook-and-loop fastener, and the entire front surface side is a hook surface F (the back surface side is not a hook surface), and is sewn to the other end side of the band portion 51 (the right side in Figure 20(a); hereinafter, referred to as the tip side as appropriate).

[0046] In this embodiment, the hook buttons 53 and 54 are made of resin. These are a member in which an upper mold has a convex engaging portion 53a and an upper mold cap are attached to sandwich the band portion 51, and a lower mold has a concave engaging portion 54a and a lower mold cap are attached to sandwich the band portion 51, respectively, and are configured so that the convex portion of the upper mold fits detachably into the concave portion of the lower mold. Also, the convex button 53 and the concave button 54 are written here to distinguish them for the purpose of explanation, and the first engaging portion 53 and the second engaging portion 54 can be arranged in reverse. The same applies to the following embodiment 3, etc.

[0047] In this embodiment, there is a band 50A with a length of 200 mm for the band portion 51A, which is suitable for use when the arm circumference is 250 mm to 300 mm, and a band 50B with a length of 270 mm for the band portion 51A, which is suitable for use when the arm circumference is 300 mm to 450 mm, and they can be used interchangeably as appropriate. Therefore, the band can be selected according to not only the arm size but also the thickness of the clothing, etc., as appropriate. For example, it can be used when wearing thick winter clothing. In addition, the band portion 51 is made of a polyester-nylon-polyurethane composite material with excellent elasticity as a whole, and since it stretches and contracts according to the movement of the arm when worn, the feeling of tightness can be reduced. Furthermore, the width of the band portion 51 is large enough not to bite into the arm, and as described above, it is approximately the same size as the vertical width of the right band insertion hole 22 and the left band insertion hole 23 of the main body portion 10 (1 to 2 mm smaller than the vertical width). In this embodiment, a 25 mm one is used as an example.

[0048] As shown in FIG. 20(c), the locking portion 60 has a shape like an isosceles trapezoid rotated 90 degrees to the right, and its tip 61 (right end in FIG. 20(c)) has a width substantially equal to that of the band portion 51A, and its rear end 62 (left end in FIG. 20(c)) is wider than that of the band portion 51A. Therefore, the upper part of the locking portion 60 is an upward protruding portion 63a that protrudes upward from the band portion 51A, and the lower part of the locking portion 60 is a downward protruding portion 63b that protrudes downward from the band portion 51A. In this embodiment, the width of the rear end 62 is formed to be approximately 15 mm wider than the width of the band portion 51. The overall length of the locking portion 60 (horizontal length in FIG. 20) is approximately 40 mm.

[0049] The rear end portion 60a of the locking portion 60 is overlapped from the rear so that the front surface (hook surface F) side is in contact with the back surface (surface other than the loop surface R) side of the tip portion 51a (in this embodiment, a portion 8 to 14 mm long from the tip side) of the band portion 51, and both members 51A, 60 are sewn together in the short direction (vertical direction in FIG. 20) at the center of the overlapping portion (tip portion 51a). The length of this sewing line 64 (broken line) is longer than the width of the band portion 51A. By giving the band 50A such a shape and structure, the locking portion 60 inserted into the left band insertion hole 23 (or band insertion hole 22) functions as a retainer when the armband 1 is worn on the arm. Details of this will be described later.

[0050] Here, a method of wearing the armband 1 on the left arm when the user wears it with the right hand will be described. Fig. 22 is a schematic diagram for explaining the method of wearing the armband 1, in which (a) to (c) show the band 50 attached to the main body 10 in preparation for putting the armband 1 on the arm, and (d) to (e) show the armband 1 being actually put on by putting it on the arm. Specifically, Fig. 22(a) shows the base end of the band 50 being inserted into the right band insertion hole 22 of the main body 10, (b) shows the base end of the band 50 being fixed to the right band insertion hole 22 of the main body 10, (c) shows the locking part 60 being inserted into the left band insertion hole 23 of the main body 10, (d) shows the locking part 60 being inserted into the left band insertion hole 23 of the main body 10, and the ring of the ring-shaped armband 1 being enlarged in order to wear it on the arm, and (e) shows the locking part 60 being pulled and fixed after the arm is inserted into the ring-shaped part. In addition, arms are not shown in FIG.

[0051] A method of attaching the band 50 to the main body 10 of the armband 1 will be described. The user selects one of the two types of bands 50 that has a length that suits the user's build and clothing. The base end side of the band portion 51 of the selected band 50 is fixed to the main body 10 with its loop surface R facing the front side. Specifically, as shown in FIG. 22(a), the base end side of the band portion 51 is inserted from the front side of the right band insertion hole 22, and as shown in FIG. 22(b), the band portion 51 is inserted through the right band insertion hole 22 so that only the convex button 53 faces the back side, and the convex button 53 and the concave button 54 are engaged with each other, resulting in the state shown in FIG. 17 above. Since the main body 10 is a semi-rigid member, when inserting the convex button 53, the right side edge portion and the left side edge portion of the right band insertion hole 22 can be pushed backward and forward, respectively, to widen the hole to a diamond shape (right side view), so that the base end side of the band portion 51 can be easily attached.

[0052] Thereafter, as shown in FIG. 22(c), the band portion 51 is in an untwisted state, and the locking portion 60 and the tip side of the band portion 51 are inserted into the left band insertion hole 23. Specifically, after the tip 61 of the locking portion 60 is inserted from the back side of the right band insertion hole 22, for example, the upper protrusion 63a and the lower protrusion 63b of the locking portion 60 are folded inward (downward and upward, respectively) to deform the width to be smaller than the length of the vertical hole of the left band insertion hole 23, and the left band insertion hole 23 is widened in a manner substantially similar to the above-mentioned right band insertion hole 22, and then inserted. Note that the folded upper protrusion 63a and the lower protrusion 63b return to their original shape (approximately isosceles trapezoidal shape) due to the nature of the material after being inserted into the left band insertion hole 23. In this way, the armband 1 and the band 50 are attached to the main body 10, and the armband 1 becomes annular as shown in FIG. 22(d). When worn on the right arm, band 50 can be rotated 180 degrees and attached to main body 10 in the opposite direction to when worn on the left arm. Specifically, in the stage shown in Figure 22(a), the base end side of band portion 51 is attached to left band insertion hole 23 of main body 10.

[0053] Next, a method of putting the armband 1 on the arm will be described. As shown in FIG. 22(d), the user enlarges the ring of the armband 1, holds the main body 10 with the right hand, and inserts the arm inside it. At this time, the main body 10 is moved to the desired height of the upper arm by sliding it on the band 50 side so as to lift it off the clothing. Then, after moving the main body 10 to the desired height, the direction of the main body 10 is adjusted so that it faces outward, and the engaging portion 60 (hook tape) is pulled with the right hand as shown in FIG. 22(e) to adjust it to the desired tightness, and this is engaged and fixed to the band portion 51 (loop tape). When engaged, the tip portion 51a (seam allowance portion, etc.) of the band portion 51 is hidden inside, so that the design is good when worn. In this way, the user can easily put the armband 1 on the arm with one hand.

[0054] When the locking portion 60 is fixed, if the band portion 51 is not yet fastened, the armband 1 rotates counterclockwise (as viewed from above) by pulling the locking portion 60 in a substantially tangential direction along the loop. Therefore, when fastening the band portion 51, the main body portion 10 is oriented toward the front of the user from the desired orientation, and the band portion 51 is slightly fastened, the orientation of the main body portion 10 is checked, and the locking portion 60 is pulled and rotated as appropriate. This process is repeated, so that the orientation of the main body portion 10 can be adjusted and fastened, and the main body portion 10 can be fixed in a desired position. Since the band portion 51 and the locking portion 60 are hook-and-loop fasteners, the degree of fastening can be finely adjusted. When the armband 1 is to be worn on the right arm, the main body portion 10 and the locking portion 60 can be operated with the left hand.

[0055] Here, the slip-off prevention function of locking portion 60 in the state shown in Fig. 22(d) will be described with reference to the drawings. Fig. 23 is a partially enlarged view showing the state in which the left band insertion hole 23 side of main body 10 in Fig. 22(d) is viewed from above, and is a schematic diagram for explaining the slip-off prevention function of locking portion 60. As shown in Figure 23, even if the band portion 51 is pulled in the direction of the arrow, because a locking portion 60 larger than the left band insertion hole 23 is sewn to the tip side, there is almost no risk of the band 50 coming off the left band insertion hole 23. Specifically, as shown in Figure 20(c), the locking portion 60 has an upper protrusion 63a and a lower protrusion 63b, and because the width of the locking portion 60 at the position of the sewing line 64 is larger than the vertical width of the left band insertion hole 23, these are caught and prevent the band 50 from coming off. Furthermore, as described above, by positioning the sewing line 64 inward from the rear end 62 of the engagement portion 60 and making the lateral length of the rear end portion 60a1 5 to 10 mm, for example, when the belt main body portion 51 is pulled, as shown in FIG. 23, the rear end portion 60a1 of the engagement portion 60 beyond the sewing line 64 deviates from the left band insertion hole 23 to the center of the main body portion 10 (the right side in FIG. 23) and gets caught.

[0056] In this way, the locking portion 60 of the armband 1 prevents it from slipping off, so when passing the arm inside the armband 1, the ring shape can be maintained even if only the main body portion 50 is held and moved. Even when the wearer is wearing thick clothing, the band portion 51 stretches appropriately, making it easy to move. Also, the locking portion 60 is located on the outside of the main body portion 10, so it does not get in the way when moving it. When removing the armband 1, the locking portion 60 can be peeled off from the band portion 51 and the armband can be easily removed from the arm by performing the steps in the reverse order to when it was worn.

[0057] Here, a band 50A', which is a modified example of the band 50A, will be described. FIG. 24 shows the band 50A', (a) is a front view, (b) is a rear view, and (c) is a partially enlarged view of (a). FIG. 25 is a schematic explanatory diagram for explaining how the armband 1 to which the band 50A' is attached is worn by putting the arm around the arm, (a) shows how the locking part 60 is inserted into the left band insertion hole 23 of the main body 10, and the ring of the ring-shaped armband 1 is enlarged in order to wear it on the arm, (b) shows how the locking part 60 is pulled and fixed after the arm is inserted into the ring-shaped part, and (c) is a schematic diagram for explaining the slip-off prevention function of the locking part 60. In the following explanation, parts different from the second embodiment will be explained, and parts with structures basically similar or substantially similar to those of the armband 1 of the second embodiment will be given similar or substantially similar symbols and names, and duplicate explanations will be omitted.

[0058] As shown in FIG. 24, the band 50A' is different from the band 50A only in the surface to which the locking portion 60 is attached. Specifically, the back surface (the surface other than the hook surface F) of the locking portion 60 is overlapped and sewn from the rear so as to contact the front surface (loop surface R) of the band portion 51. Therefore, as shown in FIG. 25, when the loop formed by the main body portion 10 and the band 50A' is enlarged, that is, when the band portion 51 is pulled, as shown in FIG. 25(c), the left side portion 13 of the main body portion 10 is sandwiched and caught between the rear end portion 60a1 of the locking portion 60 and the band portion 51 from the sewing line 64. Since the locking portion 60 is aligned along the surface of the main body portion 10 and the hook surface F faces outward, there is little risk of the locking portion 60 touching the arm or clothing (see FIG. 25(a)).

[0059] The armband 1 according to an embodiment of the present invention can be easily worn by a user with one hand, and the length of the armband 1 can be adjusted with one hand to achieve a desired tightness when worn. As described above, when wearing the armband 1 on the arm, the locking portion 60 has a function of preventing it from slipping off, so that the armband 1 can be moved while maintaining its ring shape no matter where it is held. Also, by holding the main body 10 and lifting it, and moving it by sliding the band 50 side on the surface of the arm or clothing, the main body 10 can be easily moved to a desired height without getting caught on the anti-slip portion on the back side of the main body 10. Also, by pinching and operating the locking portion 60 as described above, the band 50 can be worn with a desired tightness while adjusting the main body 10 to a desired direction.

[0060] After the armband 1 is worn, the main body 10 is less likely to slip off because a non-slip material is used on the back side. In addition, the entire band 51 is stretchable, so the length can be adjusted over a wide range, and the tightness of the band 50 can be adjusted to suit the wearer's physique and the thickness of the clothing worn. It fits the arm comfortably and is unlikely to get caught on protruding objects.

[0061] The main body 10 of the armband 1 is provided with a lower protrusion 21 and an upper protrusion 24a, etc., and has a more sophisticated design than conventional ones. The upward and downward curved shapes of the lower protrusion 21 and the upper protrusion 24 prevent the main body 10 from digging into the arm. The protruding shapes of the lower protrusion 21 and the upper protrusion 24a also have the effect of preventing the armband 1 from shifting in the up, down, left and right directions. Furthermore, the upper protrusion 24a, the upper right protrusion 24b and the upper left protrusion 24c have the role of reducing the risk that the display unit 15 is covered by clothing, making the transmitted information invisible to the surroundings. In addition, by minimizing the size of the main body 10 while ensuring a sufficient display unit 15 to display the transmitted information, it is possible to reduce the stiffness and stuffiness when worn, without covering the entire arm circumference.

[0062] The armband 1 of the present invention has a simple structure with few parts, and since the main body 10 and the band 50 are detachable, they can be replaced, making it economical. When wearing cold weather gear and thick clothing, it is possible to deal with this by replacing only the band 50 with a longer one (band 50A with band 50B). Also, when the loop surface of the hook-and-loop fastener becomes damaged or deteriorated with use and the adhesive power decreases, only the band 50 can be replaced with a new one. Also, for example, when a person's position (job title) changes depending on the work site, multiple main bodies 10 corresponding to the respective work sites can be prepared, and the same band 50 can be attached and used as appropriate.

[0063] The shape, size, and configuration of each member of the armband 1 are not limited to the above-mentioned embodiment, and as long as the armband 1 has a structure that prevents the armband 1 from slipping off and can be easily worn with one hand, it is of course possible to change the shape, size, and configuration of the armband 1 without departing from the gist of the present invention. In this embodiment, a synthetic resin material is used for the main body 10, but this is not limited to this, and any flexible sheet-like or approximately sheet-like material may be used, and other materials such as synthetic leather, genuine leather, cloth, and rubber may be used. In this embodiment, the armband 1 is provided with two types of bands 50A and 50B with different lengths, but this is not limited to this, and at least one band 50 may be provided. Furthermore, the convex button 53 and the concave button 54 are not limited to the hook buttons 53 and 54, and may be any combination of a button and a buttonhole, or a hook and a hook receiver, as long as the hook and the hook can be fixed to the main body 10. Also, the convex button 53 and the concave button 54 may be provided on the main body 10 side and the band 51 side, respectively, and may be fixed by engaging them.

[0064] <Example 3> Next, an armband 2 according to a third embodiment of the present invention will be described. Fig. 26 is a front view of main body 10α of armband 2 according to the third embodiment. Fig. 27 is a rear view of band 50A2 of armband 2 according to the third embodiment and its modifications 50A3 and 50A4. Fig. 28 is a front view of locking portion 602 of armband 2 according to the third embodiment. Fig. 29 is a front view of locking portion 603, which is a modification of locking portion 602. As shown in Fig. 26, armband 2 of Example 3 differs from armband 1 of Example 2 mainly in the configuration of main body portion 10. Also, as shown in Fig. 27, the back side of band 50A2 is treated with an anti-slip coating. In the following explanation, only the parts that differ from Example 2 will be explained, and parts that are basically the same or approximately the same as those in armband 1 of Example 2 will be given the same or approximately the same reference numerals and names, and duplicate explanations will be omitted.

[0065] As shown in FIG. 26, the armband 2 of Example 3 is provided with a pocket portion 16 (pocket-shaped display portion) into which a sheet-shaped display member such as paper can be inserted replaceably on the surface side of the main body portion 10α instead of the display portion 15 (see FIG. 19(a)). The pocket portion 16 is a rectangular transparent synthetic resin sheet, and its periphery is pressure-bonded to the surface of the main body portion 10α. The main body portion 10α is also provided with a slit 17 for inserting the display member, which is formed approximately parallel to a position inside the right side edge of the pocket portion 16. The slit 17 has a configuration approximately similar to that of the attachment hole 25, except for its length and orientation. Note that a rear view of the main body portion 10α of the armband 2 of Example 3 is omitted, since it is approximately similar to the main body portion 10 of Example 2, except for the presence or absence of the slit 17.

[0066] Although not shown, the display member is a sheet-like member such as paper on which transmission information is written or printed, for example, a business card, and in this embodiment, the size (60 mm x 100 mm) is set so that a normal-sized business card (55 mm x 91 mm) can be inserted, so that the main body 10α has a larger shape (95 mm x 150 mm in this embodiment) than the main body 10 of embodiment 2. Note that, since the pocket portion 16 is provided in the main body 10α, it is also possible to adopt a configuration in which the middle sheet-like member 102 for reinforcement is not sandwiched.

[0067] Fig. 27(a) is a rear view of the band 50A2 of the armband 2 of the third embodiment, (b) and (c) are rear views of a band 50A3 and a main body 50A4, which are modifications of the band 50A3, (d) is an enlarged cross-sectional view taken along line XX in (a), (e) is an enlarged cross-sectional view taken along line YY in (b), and (f) is an enlarged cross-sectional view taken along line ZZ in (c). For convenience, Figs. 27(d) to (f) show only cut surfaces. As shown in Fig. 27, the back sides of the bands 50A2, 50A3, and 50A4 are treated to prevent slipping.

[0068] As shown in FIG. 27(a), the band portion 51A2 of the band 50A2 of the armband 2 of the third embodiment has a line-shaped anti-slip G1 bonded to the center line extending in the longitudinal direction of the band portion 51A2. The anti-slip G1 is made of a material having an anti-slip effect, such as synthetic rubber or natural rubber. In this embodiment, silicone rubber is used, and the anti-slip G1 also expands and contracts in accordance with the expansion and contraction of the band portion 51A2. The cross section of the anti-slip G1 is substantially semicircular as shown in FIG. 27(d), and is a shape that protrudes inward from the ring, so that it can effectively prevent slippage. Note that the anti-slip G1 is provided on the entire band portion 51A2 (from end to end), but is not limited to this, and may be provided on a part such as the center portion, or may be provided as shown by a dashed line. In other words, the anti-slip G1 may be provided in various shapes as appropriate as long as it has an anti-slip function.

[0069] For example, as a modification of the non-slip element G1, two linear non-slip elements G2 extending in the width direction of the band portion 51A3 as shown in Fig. 27(b) and (e) or multiple semicircular non-slip elements G3 as shown in Fig. 27(c) and (f) may be used. These are provided on the base end side of the band portions 51A3 and 51A4. Also, if the non-slip element G3 shown in Fig. 27(f) is shaped with a right-angled cutout on the bottom, it makes it easier to move the armband 2 when it is put on, and makes it less likely to come off after it is put on.

[0070] As shown in FIG. 28, the locking portion 602 of the armband 2 of the third embodiment has a knob portion 61a that has been heat-treated to have a substantially semicircular shape at the center of the tip side. The hook of this knob portion 61a is crushed by heat treatment, and when the user removes the armband 2, for example, the user can insert the tip of the thumb and pinch it to easily peel it off from the band portion 51. Since the hooks on the upper and lower sides of the knob portion 61a are not crushed, the armband 2 is locked to the belt main body portion 1, and does not roll up and does not get in the way. In addition, the hooks of the upper protrusion 63a2 and the lower protrusion 63b2 of the locking portion 602 are also crushed by heat treatment so that the hooks do not get caught on the surface of the clothing. The band 50 of the armband 2 of the third embodiment is omitted because it is substantially the same as that of the second embodiment except for the locking portion 602.

[0071] The locking portion 603, which is a modification of the locking portion 602 of the armband 2 of the third embodiment, is substantially rectangular as shown in FIG. 29, and has a shape in which the upper right part of a rectangle is obliquely cut out. The locking portion 603 has a substantially triangular upper protrusion 63a3 and a substantially rectangular lower protrusion 63b3, which protrude above and below the width of the band portion 51. The upper protrusion 63a3 and the lower protrusion 63b3 are also heat-treated to crush the hooks so that they do not get caught on the surface of clothing, as in the case of the locking portion 602. The substantially rectangular lower protrusion 63b3 has a non-slip treatment S on its front and back surfaces, which is, for example, a coating of synthetic resin or rubber. When the user wants to remove the armband 2, the user can easily peel off the locking portion 603 from the band portion 51 by pinching the tip side of the lower protrusion 63b3 to which the non-slip treatment S has been applied. Furthermore, this downward protrusion 63b3 acts as a slip prevention member that comes into contact with the outer surface of the clothing while the armband 2 is worn on the arm, thereby preventing the armband 2 from slipping off.

[0072] Armband 2, which is an embodiment of the present invention, has the same effect as armband 1 of embodiment 2, and also allows display members to be placed in pocket 16 for appropriate exchange of transmitted information. Also, armband 2 can be easily removed by providing knob 61a and downward protrusion 63b3 on fastening parts 602 and 603. Furthermore, anti-slip treatments G1, G2, and G3 are applied to band parts 50A2, 50A3, and 50A4, thereby preventing armband 2 from shifting in the up, down, left, and right directions when worn.

[0073] The shape, size, configuration, etc. of each component of the armband 2 are not limited to the embodiment described above, and as in the case of Example 2, various modifications can be made without departing from the spirit of the present invention as long as the configuration has a retaining feature and allows easy wearing with one hand.

[0074] <Example 4> Next, an armband 3 according to a fourth embodiment of the present invention will be described. Fig. 30 shows main body 10β of armband 3 according to the fourth embodiment, with (a) being a front view, (b) being a rear view, (c) being a view showing an example of front mesh fabric 301, and (d) being a view showing an example of back mesh fabric 303. Fig. 31 is a schematic cross-sectional view showing the configuration of cushioning material 302. As shown in Fig. 30, the armband 3 of Example 4 has a different configuration of main body 10 from the armband 1 of Example 2 and the armband 2 of Example 3. In the following explanation, only main body 10β that is different from Example 2 etc. will be explained, and explanation of other configurations will be omitted. Furthermore, configurations that are basically the same or approximately the same as those of armband 1 of Example 2 etc. will be given the same or approximately the same reference numerals and names, and duplicate explanations will be omitted. Note that the dashed lines in Figs. 30(a) and (b) indicate seams sewn by a sewing machine or the like.

[0075] The main body 10β is made of a fiber material such as cloth and / or knitted fabric, and as shown in Fig. 30, it is made up of a mesh main body 30 made of a thick, sheet-like woven or knitted fabric in a substantially rectangular shape, and piping parts 31-34 that wrap around its periphery. The mesh main body 30 has a three-layer structure, consisting of two sheet-like mesh fabrics (front mesh fabric 301 and back mesh fabric 303) and a sheet-like cushioning material 302 (not shown) sandwiched between them. The opposing surfaces of these are bonded together to form an integrated structure.

[0076] The front mesh fabric 301 on the front side is a woven or knitted fabric made of chemical fibers with small holes (fine mesh), and the front side of the fabric serves as a display section 35 on which communication information can be printed or otherwise displayed. In contrast, the rear mesh fabric 303 on the rear side is a woven or knitted fabric with larger holes (coarser mesh) than the front mesh fabric 301, allowing heat and moisture to escape more easily. In this embodiment, the front mesh fabric 301 has a 1 mm 2 The mesh fabric 303 has a plurality of holes as shown below. As shown in FIG. 30(d), the ground portion M and mesh hole portion H of the back mesh fabric 303 form a honeycomb structure. The ground portion M is made by weaving chemical fibers such as polyester, and has a substantially circular cross section and a certain thickness. The thickness of the back mesh fabric 303 is preferably 1 to 8 mm (more preferably 2 to 5 mm), and the size of the mesh hole portion H is preferably 1 to 100 mm. 2 (More preferably, 5 to 60 mm 2 ).

[0077] 31, the cushioning material 302 is a low-density member made of a plurality of thin fibers K extending in the thickness direction, and is made of a synthetic resin material such as polyester. By sandwiching the cushioning material 302 between two mesh fabrics (front mesh fabric 301 and back mesh fabric 303), it is possible to improve breathability.

[0078] The piping parts 31, 32, 33, and 34 are piping members that are four edging cloth tapes, and are used to edging the lower, right, left, and upper edges of the mesh main body part 30. These prevent the edges of the mesh main body part 30 from fraying and reinforce the mesh main body part 30 so that it does not deform. In addition, the piping parts 32, 33, and 34 are formed in the center part with the right band insertion hole 22, the left band insertion hole 23, and the attachment hole 25, respectively, in a manner similar to making a buttonhole. Although not shown in the figure, the back side of the piping parts 31 to 34 of the main body part 10β may be partially or entirely (except for the part where the buttonhole is formed) subjected to anti-slip processing using silicone rubber as described in the third embodiment (see FIG. 27).

[0079] The armband 3 according to one embodiment of the present invention has the same effect as the armband 1 of the second embodiment and the armband 2 of the third embodiment in terms of the same configuration, and has the effect of being breathable and preventing stuffiness. In particular, the mesh body 30 has a two-layer structure, with the front mesh fabric 301 being made of a fine mesh that is easy to print on, and the back mesh fabric 303 being made of a material having large mesh holes H, which improves breathability and prevents heat from building up, thereby preventing stuffiness. In addition, by sandwiching the cushioning material 302 between these, a gap is created, which further improves breathability. Furthermore, the back mesh fabric 303 has an uneven surface formed by the mesh holes H and the ground part M, which also prevents the armband 3 from slipping when worn.

[0080] The shape, size, configuration, etc. of each member of the main body 10β of the armband 3 are not limited to the above-mentioned embodiment, and as long as the configuration can prevent stuffiness, various changes can be made within the scope of the present invention, as in the case of Example 2, etc. For example, in this example, the mesh fabrics 301, 303 and cushioning material 302 constituting the mesh main body 30 are not limited to the above-mentioned thickness, material, structure, etc., and can of course be changed as appropriate. Also, in this example, the mesh main body 30 has a three-layer structure, but it may be made of two or more layers and may have a structure that easily releases heat and moisture.
