Description

[Technical Field]

[0001] The present invention relates to an elastic armband that can be attached to the arm of clothing such as work clothes when working at indoor or outdoor construction sites, or when directing traffic outdoors (these types of work are collectively referred to as "indoor or outdoor work" in this specification and claims). [Background technology]

[0002] Conventionally, armbands used at construction sites, for example, are made from a thin, non-stretchy, strip-shaped plastic sheet sewn into a loop, with letters, figures, symbols, etc. printed on the surface. When wearing the armband, workers would slip the armband over their clothing and secure it to their work clothes with a safety pin or clip as appropriate.

[0003] However, safety pins and clips are often made of metal, and especially when working indoors or outdoors at electrical or communication-related construction sites, attaching these conductive items to work clothes can cause electrical shorts, and in the worst case scenario, can destroy related equipment and require a lot of time to repair. Furthermore, when working outdoors, there is the risk of lightning strikes, making this undesirable from the perspective of worker safety. Also, when workers are forced to wear rain gear in rainy weather, they must first remove the safety pin from the work clothes on which they are wearing an armband, remove the armband from the work clothes, reattach the armband to the rain gear, and then reattach the armband to the rain gear with a safety pin or similar, making the process of removing and attaching the safety pin time-consuming and tedious. This is also true for outdoor traffic control and other work. Furthermore, safety pins can easily leave holes in clothing, which can damage the equipment and require a lot of time to repair. Leave it open There is also a risk of this happening.

[0004] On the other hand, there is also a method in which a long, thin, band-shaped armband is wrapped around the arm and fastened to the arm using a hook-and-loop fastener (known as Velcro: registered trademark) consisting of male and female protrusions attached to both ends of the band-shaped armband. However, such conventional armbands can slip off during use, requiring frequent adjustment, which is troublesome.

[0005] Therefore, Patent Document 1 proposes an armband 200 in which both ends of an elastic cord 202 are fixed to the inner surface of one end of an inelastic, band-shaped armband body 201 made of a plastic sheet or the like, as shown in Figures 5(a) and 5(b) attached to the present application. When putting on this armband 200, first, the arm is passed through the loop-shaped elastic cord 202 to attach the armband body 201 to the upper arm, then the band-shaped armband body 201 is wrapped around the arm, and next, fasteners 203, 204 such as flexible tapes or hooks attached to one end and the other end of the band-shaped armband body 201 are engaged to put on the arm.

[0006] The armband 200 thus configured is configured to hold the armband body 201 attached to the elastic band 202 around the upper arm by wrapping the loop-shaped elastic band 202 around the upper arm and tightening and securing it. This prevents the armband itself from slipping off the upper arm during use, compared to the conventional armbands described above, which use a band-like armband wrapped around the arm and attached using a hook-and-loop fastener. However, the armband body 201 itself is not directly attached to the upper arm, and the armband body 201 may move up and down or tilt along the upper arm, causing it to shift from the desired position on the workwear. This requires frequent adjustment of the armband's position. Furthermore, because the armband 200 is designed to elastically tighten and secure the elastic band 202 around the worker's arm, the size of the elastic band wound around the arm must vary depending on the worker's physique, whether male or female, etc. For this reason, armband 200 must be prepared in three sizes, for example, large, medium, and small, with different sizes for elastic cord 202 in addition to the size of armband body 201 itself, or, as shown in Figure 5(b), it must be equipped with an adjuster 205 that adjusts only the length of elastic cord 202.

[0007] Furthermore, as mentioned above, conventional armbands are often made of materials that cannot be washed, such as plastic sheets, which make them easily stained, unsanitary, and require frequent replacement, which creates cost issues.

[0008] Therefore, as described in Patent Document 2 and as shown in FIG. 6 attached to the present application, a looped stretchable armband 300 has been proposed which is attached to the arm of clothing when working indoors or outdoors.

[0009] In other words, the ring-style stretchable armband 300 is made by sewing a strip of stretchable material into a ring shape, printing on the surface, and having a width W and a diameter D. Furthermore, the ring-style stretchable armband 300 is configured such that an inner surface reinforcing member 301 is attached to at least one location on the inner surface of the armband 300, the inner surface reinforcing member 301 having a predetermined length (L1) along the circumferential direction of the armband 300 and extending in the width (W) direction of the armband 1 by a length approximately equal to the width (W) of the armband 1.

[0010] The ring-made stretchable armband 300 with such a structure (1) does not require fixing to work clothes with safety pins or clips, etc., and the attachment and detachment operations to work clothes (clothing) are extremely easy, and moreover, it is electrically insulating. (2) Also, printing is possible on the surface, it is excellent in weather resistance and water resistance, and furthermore, it is washable. In particular, the ring-made stretchable armband 300 is provided with an inner surface reinforcing member 301, so that wrinkles do not occur in the width direction during wearing. It has features such as these.

[0011] Furthermore, the ring-made stretchable armband 300 with such a structure, as shown in FIGS. 7(a) and (b), by providing size-adjusting surface fastener members 3,02 and 3,03, has a structure in which the diameter D of the ring-made stretchable armband 300 can be reduced to a diameter Dd (Dd < D), so that there is no need to prepare ring-made stretchable armbands of various sizes.

Summary of the Invention

Problems to be Solved by the Invention

[0013] The present inventors conducted various practical tests on the hooped stretchable armband 300 described in Patent Document 2 and found the following: As mentioned above, the hooped stretchable armband 300 described in Patent Document 2 is configured so that the diameter D of the hooped stretchable armband 300 can be changed by providing size-adjustment hook-and-loop fastener members 302, 303, but when actually using the hooped stretchable armband 300, as shown in Figure 7(b), it was found that there were problems with the operability of using the size-adjustment fastener members 302, 303 to fold the stretchable material to an appropriate length and adjust the size of the hooped stretchable armband 300 to be smaller, making it difficult to actually adjust the size of the hooped stretchable armband 300. Furthermore, this stretchable ring-style armband 300 is manufactured with a specified diameter D, and in order to adjust the size to a larger size, the stretchable armband 300 must be stretched to its maximum extent. However, as this stretching increases, the arm-tightening force increases, and there is a limit to how much it can be stretched, making further size adjustments problematic, and further improvements were desired from a practical standpoint.

[0014] The present invention relates to a further improvement of the armband.

[0015] The object of the present invention is to provide a stretchable armband that takes advantage of the above-mentioned features (1) and (2) of the loop-style stretchable armband 300 and further improves the ease of wearing by a worker when wearing the armband.

[0030] The stretchable armband according to the present invention will be described in more detail below with reference to the drawings.

[0031] Example 1 FIG. 1 and FIGS. 2(a) to (d) show an embodiment of a stretchable armband 1 according to the present invention.

[0032] The stretchable armband 1 of the present invention is made of a stretchable material and has an armband body 1A sewn into a narrow rectangular shape, i.e., a band-like shape, with a specified width (W) and length (L). The armband body 1A has specified characters, figures, symbols S, etc. printed on its outer surface 1Aa, and furthermore, a reinforcing member 10 with flexibility that prevents wrinkles from forming on the armband 1 is attached to at least one location on the inner surface 1Ab of the armband body 1A. The reinforcing member 10 has a specified length (L1) along the longitudinal direction of the inner surface of the band-like armband body 1A, and extends a length (W1) in the width (W) direction of the armband body 1A that is approximately equal to the width (W) of the armband. The stretchable armband 1 is provided with first and second adjustment fasteners 30 (30A, 30B) at both longitudinal ends of the band-like armband body 1A to secure the armband 1 to the arm with an appropriate tightening force to prevent the armband 1 from shifting from its predetermined position after being wrapped around the arm and worn. In this embodiment, a hook-and-loop fastener is preferably used as the adjustment fastener 30, and although not limited thereto, the first adjustment fastener 30A is a hook-and-loop fastener with female protrusions (loop-shaped), and the second adjustment fastener 30B is a hook-and-loop fastener with male protrusions (hook-shaped). Furthermore, a fastening aid 20 is provided at one longitudinal end of the band-like armband body 1A (in this embodiment, the end where the first adjustment fastener 30A is provided) to facilitate the wrapping of the band-like armband body 1A around the worker's arm when using the armband 1. In this embodiment, the fastening aid 20 is a loop-shaped elastic cord body made of a rubber cord. Each of the components that make up the armband 1 will now be described in detail.

[0033] Armband body 1A As shown in Figures 2(a) to 2(d), the stretchable armband 1 has an armband body 1A that can be transformed into a ring shape (i.e., a cylindrical shape) by sewing a band-shaped armband fabric member 2 made of a stretchable material that is cut into a narrow rectangular shape with a predetermined width (W0) and length (L0). The size of the armband body 1A, when contracted as shown in Figure 2(d), is 39 to 41 cm in length L and 9 to 11 cm in width W. In this embodiment, L = 40 cm, W = 10 cm. However, these dimensions are not limiting. Details will be described later. Necessary characters, figures, symbols S, etc. are printed on the surface (outer surface) 1Aa of the armband body 1A.

[0034] The stretchable material can be a stretch woven material, a stretch tricot material, or another stretchable material. These stretchable materials are preferably stretchable in both the vertical and horizontal directions. As will be described in detail later with reference to FIG. 4(b), the stretchable material is one that can stretch (expand) the diameter (D) of the loop-shaped stretchable armband 1 of the present invention to a maximum diameter that is 1.5 to 2.5 times the minimum diameter when contracted. Therefore, according to the armband of the present invention, the diameter (D) of the armband 1 can be appropriately adjusted to fit the worker's size using hook-and-loop fasteners (adjustable fasteners) 30 (30A, 30B) consisting of male and female protrusions attached to one end and the other end of the band-shaped armband body 1A. Furthermore, the resulting tightening force, utilizing the stretchability of the loop-shaped armband, effectively prevents the armband 1 from slipping off the worker's arm.

[0035] The stretchable material may be a woven, knitted, or nonwoven fabric made from synthetic fibers, such as polyamide fibers (e.g., nylon 6, nylon 66), polyester fibers (e.g., polyethylene terephthalate, polybutylene terephthalate), polyolefin fibers, acrylic fibers, or urethane fibers, either alone or in combination. Considering stretchability, printability, ease of washing, and other factors, tricot (stretch fabric) made from a combination of polyester and polyurethane fibers is particularly preferred. The fiber blend ratio is preferably about 70-90% polyester and 30-10% polyurethane.

[0036] Next, an example of a method for manufacturing the stretchable armband 1 of this embodiment will be described with reference to Figures 2(a) to (d) and 3(a) and (b). According to this embodiment, the stretchable armband 1 can be extremely suitably manufactured by sewing the above-mentioned stretchable material.

[0037] First, as shown in FIG. 2(a), a stretch fabric, which is a stretchable material, is cut to a predetermined width (W0) and length (L0) to produce a band-shaped armband fabric member 2.

[0038] As shown in Figure 2(b), the band-shaped armband fabric member 2 has both longitudinal edge portions (top and bottom edge portions) 5, 6 and both end edge portions (left and right edge portions) 3, 4 subjected to a locking process (locking processing) 7 using a locking machine to prevent fraying. The locking process width (w1) is approximately 3 to 5 mm. Any method can be used for the locking process 7 as long as it prevents fraying of the fabric edges and does not impair the stretchability of the stretch fabric 2.

[0039] Next, as shown in Figure 2(c) when viewed from the back of the armband body 1A, in this embodiment, the upper and lower edges 5, 6 of the strap-shaped armband fabric member 2 are folded once and stitched (with a double-thread stitch) 8. The fold width (w2) is about 5 to 10 mm. Of course, stitching may also be performed by folding two or three times.

[0040] FIG. 3(a) shows the state of the stitching 8 when viewed from the front, and FIG. 3(b) shows the state of the locking 7 when viewed from the back.

[0041] The left and right edges 3, 4 of the fabric member 2 of the band-like armband may also be subjected to a folded stitching process after the locking process.

[0042] The above steps produce the band-shaped armband body 1A of this embodiment, as shown in Figure 2(c). As mentioned above, it is important that the sewing process be performed so that the armband body 1A produced by sewing has a predetermined stretch rate. According to the inventor's research and experiments, the stretch rate, i.e., the ratio of the contracted diameter (minimum diameter) to the extensible diameter (maximum diameter), i.e., the extensible diameter of the armband, is preferably 1.5 to 2.5 times the contracted minimum diameter.

[0043] In other words, what is important about the above-mentioned sewing process is that the locking process 7 and stitching process 8 are not limited to those of the illustrated embodiment, and any method can be used as long as the stretch rate of the stretchable armband 1 is within the above-mentioned range.

[0044] Therefore, the stretchable armband 1 made by the sewing method of this example has an elongation rate within the above range, and is attached and fixed by utilizing the tightening force of the loop-shaped armband 1 around the arm, eliminating the need for fastening to the work clothes with safety pins, clips, etc., making it extremely easy to attach and remove from the work clothes. In addition, because it is made of synthetic fiber, it is electrically insulating.

[0045] Furthermore, it is preferable that the stretch fabric used in this example be printed with predetermined characters, figures, symbols S, etc. before cutting, and the printing method is preferably sublimation transfer printing (mechanical printing), which can produce extremely good printing.

[0046] In sublimation transfer printing, disperse dye ink is printed onto transfer paper using an inkjet printer, and the transfer paper is then placed on fabric (stretch fabric) and heated with a heat roller, causing the vaporized ink to penetrate the molecular structure of the synthetic fiber (chemical fiber) and dye it.In particular, machine printing involves a steaming process and a washing process, where the color is fixed in the steaming process and excess dye is washed away in the washing process.

[0047] Therefore, the armband of this embodiment can be printed with necessary characters, figures, symbols S, etc. in an extremely good manner, and is excellent in weather resistance and water resistance, and furthermore, is washable.

[0048] The stretchable armband 1 of the present invention was produced using various materials and sewing methods according to the above examples, but the properties of the stretchable base material (stretch fabric) and sewing process (thread) that are considered to be most preferable are shown in Table 1.

[0049] [Table 1]

[0050] The stretchable armband 1 of the present invention, made using the stretchable base material (stretch fabric) and sewing process (thread) shown in Table 1 above, is electrically insulating and suitable as an armband for indoor and outdoor construction sites. It also does not suffer from the problem of dew adhesion in humid environments that is common with conventional plastic armbands, and is gentle on the skin.

[0051] Furthermore, the expandable diameter is 1.5 to 2.5 times the minimum diameter when contracted, eliminating the need for safety pins or clips to secure the fabric to work clothes, making it extremely easy to attach and remove. Its shape retention is excellent and it does not lose its shape. Its surface can be printed using dye-sublimation transfer printing, and it is weather-resistant and water-resistant. It can also be washed frequently, eliminating the problems of dirt and sweat odors, and is cost-effective.

[0052] Reinforcing member 10 According to the present invention, as described above, a reinforcing member 10 having rigidity and flexibility that can prevent wrinkles from occurring in the armband is attached to at least one location on the inner surface 1Ab of the armband 1, in this embodiment, located in a predetermined length region approximately in the center of the armband 1 in the longitudinal direction, excluding both longitudinal end positions of the armband 1.

[0053] In this embodiment, the reinforcing member 10 is rectangular and has a predetermined length (L1) along the circumferential direction of the armband 1, i.e., along the longitudinal direction of the armband main body 1A, and extends a length (W1) in the width (W) direction of the armband main body 1A that is approximately equal to the width (W) of the armband main body 1A. In this embodiment, the length L1 of the reinforcing member 10 along the longitudinal direction of the armband main body 1A is 1 to 5 cm, and the length in the width W direction of the armband main body 1A perpendicular to the longitudinal direction, i.e., the width W1, is 9 to 11 cm, specifically, L1 = 5 cm, W1 = 10 cm.

[0054] Although the reinforcing member 10 is flexible, it must have the function of preventing the armband 1 from easily wrinkling in the width W direction, and is preferably made of a fabric or the like with a certain degree of stiffness, i.e., stiffness. Experiments by the inventors have shown that the stiffness (heart loop method) is preferably 30 to 45 mm, and more preferably 35 to 38 mm.

[0055] In this example, good results were obtained by using a hook-and-loop fastener member having either male (hook-shaped) protrusions or female (loop-shaped) protrusions that constitute the hook-and-loop fastener, and having such bending resistance. In this example, a hook-and-loop fastener member having loop-shaped protrusions (female) was used as the reinforcing member 10.

[0056] Specifically, examples of the hook-and-loop fasteners that can be used include "Magic Tape" (a registered trademark of Kuraray Co., Ltd.) and "Ecomagic" (a registered trademark of Kuraray Co., Ltd.), manufactured by Kuraray Fastening Co., Ltd., product numbers A8693Y-71 / B2790Y-00 (bending resistance (Heart Loop method): 35.5 / 38.0) and A86900-71 / B27000-00 (bending resistance (Heart Loop method): 35.3 / 36.6). While either the A (hook) tape or the B (loop) tape of this hook-and-loop fastener may be used as the reinforcing member 10, in this example, the B (loop) tape was used. As mentioned above, the length (L1) of the armband body 1A of the hook-and-loop fastener member 10 in the longitudinal direction was 5 cm, and the width (W) was 10 cm.

[0057] In this embodiment, as described above, the base material 11 side of the hook-and-loop fastener member that is the reinforcing member 10 is attached to the inner surface 1Ab of the armband body 1A, i.e., the engaging protrusions 12 are formed on the inner surface of the armband 1. Using a hook-and-loop fastener member that is B (loop) tape improves fit. In particular, when a hook-and-loop fastener member that is A (hook) tape is used as the reinforcing member 10, this, combined with the stiffness and flexibility of the reinforcing member 10 itself, increases friction between the inner surface of the armband and the clothing after wearing, depending on the type of clothing, and can prevent the armband 1 from wrinkling.

[0058] The reinforcing member 10 may be joined to the armband body 1A by gluing or sewing the entire periphery of the reinforcing member. However, in order to maintain the stretchability of the armband body 1A, it is preferable to attach the reinforcing member 10 to the armband body 1A at positions adjacent to the upper edge 1a and lower edge 1b of the armband body 1A, for example, at positions spaced about 3 to 8 mm from the upper and lower edges 1a, 1b, as shown in Figure 1. In this embodiment, the reinforcing member 10 is attached by stitching 13, 14 at the fold width (w2) of the upper and lower edges of the armband body 1A, as shown in Figures 1 and 2(c).

[0059] Thus, according to the results of the inventor's experiments, even if the inner surface reinforcing member 10 is attached to the armband 1 adjacent to the upper edge 1a and lower edge 1b of the armband 1, if a reinforcing sheet such as a hook-and-loop fastener member having an appropriate stiffness, for example, preferably 30 to 45 mm, and more preferably 35 to 38 mm, is used, the armband will not wrinkle when worn.

[0060] The number of reinforcing members 10 may be at least one on the inner peripheral surface of the armband, but if the effect is not sufficiently achieved with one member due to factors such as the size of the armband, multiple members, for example, 2 to 4 members, may be used. In the present invention, the adjustment stoppers 30 (30A, 30B) described below also function as reinforcing members, so good results were obtained by providing one member in the longitudinal center of the armband body as shown in the figure.

[0061] Adjustment stopper 30 (30A, 30B) 1 and 4(a) and (b), the stretchable armband 1 of the present invention has adjustment fasteners 30 (30A, 30B) that fasten and secure the band-like armband body 1Aa to the arm with an appropriate amount of tightening force to prevent the armband 1 from slipping off during use after the elongated band-like armband body 1A is wrapped around the arm. In this embodiment, the adjustment fasteners 30, i.e., the first and second adjustment fasteners 30A, 30B, are hook-and-loop fastener members consisting of male and female protrusions attached to both ends of the band-like armband body 1A.

[0062] In this embodiment, the first adjustment stop 30A is a rectangular hook-and-loop fastener member that is attached to one longitudinal end of the band-like armband body 1A, extending a predetermined length (L2) along the longitudinal direction of the band-like armband body 1A on the outer surface 1Aa of the band-like armband body 1A, and extending a length (W2) in the width (W) direction of the band-like armband body 1A approximately equal to the width (W) of the armband. The first adjustment stop 30A is joined to the armband body 1A by gluing or sewing (sewing) the periphery around the entire periphery of the rectangular adjustment stop 30A.

[0063] In addition, in this embodiment, the first adjustment stop 30A is arranged on the outer surface 1Aa of the armband body 1A, facing the reinforcing member 10 in the approximate radial direction of the armband 1, and as described above, also functions as a second reinforcing member.

[0064] Furthermore, the second adjustment stop 30B is a rectangular hook-and-loop fastener member located at the other longitudinal end of the armband body 1A, opposite the first adjustment stop 30A, and extending a predetermined length (L3) along the longitudinal direction of the band-shaped armband body 1A on the inner surface 1Ab of the armband body 1A and a length (W3) approximately equal to the width (W) of the armband body 1A. The second adjustment stop 30B is joined to the armband body 1A around the entire periphery of the rectangular adjustment stop 30A by adhesive or sewing. Of course, each hook-and-loop fastener member is attached with the base material side of the hook-and-loop fastener member facing the armband body 1A, just like the reinforcing member 10.

[0065] The length (L3) of the second adjustment stop 30B along the longitudinal direction of the band-shaped armband body 1A is shorter than the length (L2) of the first adjustment stop 30A described above. In other words, L2 > L3. L2 is set to be approximately 2 to 5 times longer than L3, and in this embodiment, L2 is set to 10 cm and L3 is set to 5 cm. Of course, this is not limiting, and to widen the adjustment range, for example, L2 can be set to 10 cm and L3 to 2 cm.

[0066] Therefore, by overlapping the second adjusting stop 30B with the first adjusting stop 30A, the hook-and-loop fastener members 30A, 30B can be engaged and fixed to each other. In other words, by adjusting the circumferential engagement position of the second adjusting stop 30B with the first adjusting stop 30A, the diameter (D) of the armband 1 can be adjusted.

[0067] Thus, according to the stretchable armband 1 of the present invention, by providing the size adjustment fastener 30, i.e., the hook-and-loop fastener members 30A and 30B, there is no need to prepare stretchable armbands of various sizes, which reduces costs and improves practicality.

[0068] For the first and second hook-and-loop fastener members 30A and 30B serving as the adjustment fastener 30, the hook-and-loop fastener members described in relation to the reinforcing member 10 above can be used.

[0069] Specifically, examples of the hook-and-loop fasteners that can be used include "Magic Tape" (a registered trademark of Kuraray Co., Ltd.) or "Ecomagic" (a registered trademark of Kuraray Co., Ltd.), manufactured by Kuraray Fastening Co., Ltd., product numbers A8693Y-71 / B2790Y-00 (bending resistance (Heart Loop method): 35.5 / 38.0) or A86900-71 / B27000-00 (bending resistance (Heart Loop method): 35.3 / 36.6). For example, either the A (hook) tape or the B (loop) tape of this hook-and-loop fastener may be used as the first hook-and-loop fastener member 30A, but in this embodiment, the B (loop) tape hook-and-loop fastener member was used. Therefore, the A (hook) tape hook-and-loop fastener member was used as the second hook-and-loop fastener member 30B.

[0070] As understood from the above, the hook-and-loop fastener member 30A is attached so that its engagement surface (loop protrusions) forms the outer surface 1Aa of the armband body 1A, and the hook-and-loop fastener member 30B is attached so that its engagement surface (hook protrusions) forms the inner surface 1Ab of the armband body 1A.

[0071] Stopper aid 20 In this embodiment, the fastening aid 20 is a string-like body made of an elastic material, with both ends of this elastic string attached to one longitudinal end of the band-like armband body 1A. A rubber string is preferably used as the elastic string, and examples of suitable elastic strings include flat elastic strings and round elastic strings with a moderate stretch rate (elongation). For example, flat elastic strings such as woven, braided, or corded elastic strings with a width of approximately 10-20 mm and a stretch rate of approximately 1.8-2.8 can be used. In this embodiment, a woven (flat) elastic string (manufactured by Takehaji Seisou Co., Ltd., under the trade name "Ue Tuck Elastic") with a width (W20) of 15 mm and a stretch rate of approximately 2.4 times was used. The length of the elastic string (excluding the attachment length to the armband body 1A) is set so that the diameter of the loop when formed is approximately 9-11 cm. In this example, the flat elastic cord, which is 28 cm long, is attached to the armband body 1A by sewing both ends to the approximate center of the width of the armband body 1A with a 1 cm attachment allowance (seam allowance). In other words, in Figure 2(d), L20 = 13 cm, meaning that the diameter of the elastic cord when looped is approximately 8 cm.

[0072] The fastening aid 20, i.e., the elastic string-like body (rubber string), is used to temporarily fasten the armband main body 1A to the work clothes to assist in fastening the armband main body 1A to the work clothes when putting the armband 1 on the upper arm H of the worker's work clothes, as will be described in detail later with reference to Figure 4(a).

[0073] The fastening aid 20 in the stretchable armband 1 according to the present invention is not a fastening device for fastening the armband to the work clothes, like the loop-shaped elastic cord 202 in the armband 200 described in Patent Document 1 and explained with reference to Figure 5. In other words, the string-like body constituting the fastening aid 20 in the present invention is sufficient as long as it is attached by wrapping lightly around the upper arm H of the worker's work clothes so that the armband main body 1A, which has not yet been looped, does not slip off the work clothes, and is elastic enough to prevent the armband main body 1A from falling off the upper arm H of the work clothes.

[0074] How to put on the armband 4(a) and 4(b), when wearing the stretchable armband 1 of the present invention on, for example, the upper arm of work clothes, first, the fastening aid 20, which is an elastic string-like body, is looped and passed around the arm H of the worker wearing the work clothes, and one end of the armband body 1A, i.e., in this embodiment, the end of the first adjusting fastener (hook-and-loop fastener) 30A, is temporarily fastened to the arm H of the work clothes. Next, the worker overlaps and presses the other end of the armband body 1A, which is not fastened to the work clothes, i.e., in this embodiment, the second adjusting fastener (hook-and-loop fastener) 30B, onto the first adjusting fastener (hook-and-loop fastener) 30A, engaging the first and second adjusting fasteners 30A, 30B with each other, forming the armband body 1A into a loop shape.

[0075] In the armband 1 of the present invention, the end of the band-shaped armband body 1A, where the first adjustment fastener (hook-and-loop fastener) 30A is provided, is temporarily fastened to the arm part H of the workwear as described above, so the worker can hold the second adjustment fastener (hook-and-loop fastener) 30B in one hand and press it over the first adjustment fastener (hook-and-loop fastener) 30A to engage the first and second adjustment fasteners 30A, 30B with each other, making the armband fastening operation extremely easy. Furthermore, by adjusting the mutual engagement positions of the first and second adjustment fasteners 30A, 30B as necessary, the tightening force of the armband body 1A around the arm can be adjusted to fit and secure the armband tightly around the upper arm H of the workwear. In the armband 1 of the present invention, the fastening aid 20, which is an elastic string-like body, temporarily holds the end of the first adjustable fastener (hook-and-loop fastener) 30A on the arm part H of the workwear, as described above, and prevents the armband main body 2A from falling off the arm part H of the workwear, thereby allowing the armband main body 1A to be easily moved along the upper arm part H. In other words, the fastening aid 20 does not hinder the movement of the armband main body 1A along the arm part H, and therefore, when attaching the armband 1 of the present invention to the arm part H, the armband main body 1A is wrapped around the upper arm part H of the workwear and tightly fixed, and at the same time, the armband 1 itself can be easily moved along the arm part H to adjust and move the armband 1 to a predetermined installation position on the arm part H.

[0076] In Figure 4(b), in this embodiment, as described above, the length L of the armband body 1A is 40 cm, and the lengths L2 and L3 of the first and second adjustment fasteners are 10 cm and 5 cm, respectively, so the minimum diameter of the loop-shaped armband 1 is approximately 9 cm, while the maximum diameter can be expanded to approximately 15 to 20 cm, taking into account the stretchability of the armband body 1A.

[0077] The stretchable armband of the present invention configured as described above eliminates the need to prepare armbands of various sizes, does not require fastening to work clothes with safety pins or clips, and is extremely easy to attach to and remove from work clothes (garments). Furthermore, armband 1 is electrically insulating, improving its practicality. Its surface can be printed, it has excellent weather resistance and water resistance, and it is washable. Furthermore, the stretchable armband of the present invention does not wrinkle in the width direction while worn. [Explanation of symbols]
