Description

[Technical Field]

[0001] The present invention relates to a rotation stopper for preventing a nameplate or other item hanging from the neck from rotating around the chest. [Background technology]

[0002] At events such as exhibitions, conferences, and seminars, it is common for participants to wear nameplates on a lanyard. These nameplates are important tools for identifying participants' names and affiliations, and they facilitate quick communication and networking. One of the problems with using such nameplates is that they tend to rotate. As shown in Figure 4, nameplate N typically consists of a card containing the name and affiliation stored in a transparent holder, to which a neck strap S is attached. The neck strap S is adjusted to a length that places the nameplate close to the user's chest. If the nameplate N floats near the user's chest while the user is moving, the nameplate N tends to rotate. If the nameplate N is turned upside down, the name and affiliation may become invisible (see Figure 5). This problem not only hinders smooth interaction between participants, but also leads to a decrease in the efficiency of the event.

[0003] Various measures have been proposed to prevent nameplates from rotating, such as using a non-slip material on the back of the nameplate or attaching the nameplate to the shirt with a clip. Conventional techniques relating to preventing a necklace from rotating around the neck are known, such as those disclosed in Patent Document 1. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3058469 Summary of the Invention [Problem to be solved by the invention]

[0005] However, these conventional solutions do not adequately solve the above problems: the anti-slip material can damage clothing, and the clips can be difficult to adjust, limiting their effectiveness. The present invention has been made in consideration of the current situation, and aims to provide a functional and easy-to-use anti-rotation device that can stably hold hanging items such as nameplates without rotating them. [Means for solving the problem]

[0006] [First Invention] The anti-rotation device for a hanging object according to the present invention for solving the above problems comprises: A rotation stopper (1) attached to a neck strap (S) for hanging a neck-hanging object (N), A plate body (2), A pair of parallel left slits (3) are cut into the left end of the plate body (2), a right slit (4) cut in a pair in parallel on the right end of the plate body (2); The left slit (3) is configured so that the left string (SL) seen on the left side of the neck string (S) when facing the user can be inserted, and the right slit (4) is configured so that the right string (SR) seen on the right side of the neck string (S) when facing the user can be inserted.

[0007] According to the configuration of the first invention, the neck straps (left and right straps) are passed through the left and right slits of the plate body from the front and back of the plate body, respectively, so that the plate body is hung on the neck straps near the user's chest. As a result, even if the item hanging from the neck is about to rotate while the user is moving, the plate body hits the user's chest and stops the rotation. Therefore, the item hanging from the neck is prevented from rotating and turning inside out, and the item can be held stably. In addition, in the configuration of the first invention, a pair of left and right slits are cut into the left and right ends of the plate body, into which the neck strap can be inserted from the left and right sides. Therefore, by passing the neck strap through these paired slits from the front and back of the plate body, the plate body is less likely to come off the neck strap. Furthermore, the position can be adjusted by sliding the plate body above and below the neck strap, making it possible to find a more stable position for the neck strap. In other words, a functional and easy-to-use anti-rotation device can be provided that is easy to attach to the neck strap and has little risk of coming off. Furthermore, according to the configuration of the first invention, the plate body can be stably held near the chest, so the plate body can also be used as a display medium. For example, the plate body can be effectively utilized by displaying the company name or department name or advertisement on the front of the plate body. Of course, the present invention also prevents the plate body used as a display medium from rotating. Usually, nameplates used as neck hangings are hung lower than the chest, so they are often out of the line of sight of the person facing them. With the configuration of the present invention, the plate body can be held in a higher position near the chest, making it more visible to the other person. This allows the plate body to be used more effectively as a display medium.

[0008] [Second Invention] The anti-rotation device according to the second invention has the configuration of the first invention, The left slit and the right slit are provided with hook-shaped locking portions (3a).

[0009] According to the second aspect of the present invention, the left and right slits are provided with hook-shaped locking portions, and by passing the neck strap through these portions, the neck strap is even less likely to come off the left and right slits, thereby improving the reliability of the attachment of the anti-rotation device.

[0010] [Third Invention] The anti-rotation device according to the third invention has the configuration of the first invention, The plate body is configured so that when the neck string is inserted into the left slit and the right slit, a U-shaped auxiliary slit (5) extending in the horizontal direction of the plate body is provided.

[0011] According to the third aspect of the invention, the plate body can be attached to the user by passing the edge of the user's shirt or other item through the U-shaped auxiliary slit while the plate body is suspended over the neck string. This further stabilizes the plate body and improves the anti-rotation effect of the neck hanging item. [Brief explanation of the drawings]

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the embodiments described below are examples of application of the present invention, and the scope of the invention is not limited to these embodiments.

[0014] FIG. 1 shows a rotation stopper 1 according to an embodiment. The anti-rotation device 1 is attached to a neck strap S from which a nameplate N is hung as shown in FIGS. 1, the anti-rotation device 1 is formed by providing various slits in a horizontally elongated rectangular plate body 2. The plate body 2 is formed, for example, by punching out a resin plate material into a rectangular shape of a predetermined size and then cutting the various slits into it.

[0015] A left slit 3 and a right slit 4 are provided at the left and right ends of the plate body 2. The left slits 3 are cut in a pair parallel to each other at the left end of the plate body 2. The right slits 4 are cut in a pair parallel to each other at the right end of the plate body 2. As shown in Figure 2, the left slit 3 is designed to allow insertion of the left string SL of the neck strap S, which is visible on the left side when facing the user, and the right slit 4 is designed to allow insertion of the right string SR of the neck strap S, which is visible on the right side when facing the user. In other words, both slits are open slits with one end opening to either the left or the right. The slit widths of the left slit 3 and the right slit 4 are almost uniform and slightly narrower than the thickness of the neck strap S. This prevents the neck strap S from easily slipping out of the left slit 3 and the right slit 4 when the neck strap S is inserted into each slit.

[0016] As shown in Figures 1 and 3, the open ends of the left slit 3 and the right slit 4 are provided with arc-shaped notched receiving portions 3a and 4a. The slit widths of these receiving portions 3a and 4a increase toward the tips. As a result, when the neck strap S is inserted into the left slit 3 or the right slit 4, these receiving portions 3a and 4a serve to guide the neck strap S into each slit.

[0017] L-shaped (hook-shaped) locking portions 3b, 4b are provided at the closed ends of the left slit 3 and the right slit 4. When inserting the neck strap S into the left slit 3 and the right slit 4, sliding the neck strap S toward the back of each slit causes it to fit into these locking portions 3b, 4b.

[0018] A U-shaped auxiliary slit 5 is provided in the center of the plate body 2. The auxiliary slits 5 are connected so as to extend horizontally of the plate body 2 when the neck strap S is inserted into the left slit 3 and the right slit 4. Arc portions 5a, 5a larger than the slit width are formed on both ends of the auxiliary slit 5. The arc portions 5a, 5a make the portion of the plate body 2 surrounded by the U-shaped auxiliary slit 5 more likely to bend front and back.

[0019] When using the anti-rotation device 1, as shown in Figure 2, the plate body 2 is held at a sufficient distance above the nameplate N. The neck straps S (left strap SL and right strap SR) are passed through the left slit 3 and right slit 4 of the plate body 2 from the front and back of the plate body 2. This allows the plate body 2 to be hung over the neck straps S (left strap and right strap) near the user's chest. In the example of FIG. 2, the neck string is led out through the slits from the back side of the plate body 2 to the front side, but the lead-out direction from the front to the back may be reversed.

[0020] With the anti-rotation device 1, even if the nameplate N is about to rotate while the user of the nameplate N is moving, the plate body 2 comes into contact with the user's chest area and stops the rotation. This prevents the nameplate N from rotating and turning over, and allows the nameplate N to be held stably. Furthermore, a pair of left slits 3 and right slits 4 are cut into the left and right ends of the plate body 2, and by passing the neck strap through these paired slits from the front and back of the plate body 2, the plate body 2 is less likely to come off the neck strap S. Furthermore, the position of the plate body 2 can be adjusted by sliding it above and below the neck strap S, making it possible to find a more stable position for the nameplate N. This makes it possible to realize a functional and easy-to-use anti-rotation device 1 that is easy to attach to the neck strap and has little risk of coming off.

[0021] Furthermore, since the anti-rotation device 1 can stably hold the plate body 2 near the chest, the plate body 2 can be used as a display medium. For example, if information display 6 such as a company name is printed on the plate body 2, the information display 6 will be more visible to the person facing it than the nameplate N. This allows the plate body 2 to be effectively used as a display medium. The plate body 2 itself will not rotate, preventing the information display 6 from becoming obscured.

[0022] Furthermore, the left slit 3 and the right slit 4 of the anti-rotation device 1 are provided with hook-shaped locking portions 5a, so that by passing the neck strap S through these portions, the neck strap S is even less likely to come off the left slit 3 and the right slit 4. This increases the reliability of the attachment of the anti-rotation device 1.

[0023] Furthermore, with the anti-rotation device 1, the user can attach the plate body 2 to themselves by passing the edge of the user's shirt or the like through the U-shaped auxiliary slit 5 while the plate body 2 is suspended over the neck strap S. In other words, the plate body 2 can be clipped to the user's clothing or the like. This further stabilizes the plate body 2, improving the anti-rotation effect of the nameplate N.

[0024] [Variations] Although the anti-rotation device 1 has been described above as an embodiment of the present invention, the embodiment is not limited to this and various modifications may be made. In the above-described embodiment, the anti-rotation device is used on a nameplate, but it is not limited to this as long as it can be distinguished between the front and back. For example, the anti-rotation device of the present invention can be used on items such as advertisements, identification tags, and decorative items that hang from the neck. The plate body may be made of a material such as hard resin, soft resin, composite material such as CFRP (carbon fiber reinforced plastic), metal, wood, paper, ceramic, or the like. The shape of the plate body does not necessarily have to be rectangular, but may be circular, elliptical, oval, rhombus, trapezoid, hexagonal, octagonal or other shapes. The material and structure of the neck strap are not limited, and it may be made of synthetic or natural fibers, or may have a chain structure. The U-shaped auxiliary slit may be reversed in its left-right direction, or the slit may be inclined to the extent that the clipping effect is not lost. [Explanation of symbols]
