Description

[Technical field]

[0001] The present disclosure relates to a splash suppression member that suppresses splashes. [Background technology]

[0002] Various types of droplet suppression members for suppressing droplets have been known in the past. Utility Model Registration No. 3228497 describes a droplet diffusion prevention partition. The droplet diffusion prevention partition includes a left side plate, a center plate, and a right side plate. Each of the left side plate, the center plate, and the right side plate is frame-shaped, and a transparent sheet portion is provided on the inside of each of the left side plate, the center plate, and the right side plate.

[0003] The left side plate and the central plate are connected to each other via a first bent portion, and the central plate and the right side plate are connected to each other via a second bent portion. This allows the left side plate, the central plate and the right side plate to be foldable via the first bent portion and the second bent portion. The central plate has a left side portion and a right side portion, and a third bent portion extending vertically is provided between the left side portion and the right side portion. This allows the central plate to be further foldable via the third bent portion.

[0004] The left side plate, the center plate and the right side plate are made of paper. The transparent sheet is made of a flexible transparent film, and the opposite side of the transparent sheet of the droplet diffusion prevention partition can be seen from one side of the transparent sheet. When the droplet diffusion prevention partition is set up on a desk, a person on one side of the droplet diffusion prevention partition can see a person on the opposite side through the transparent sheet. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Utility Model Registration No. 3228497 Summary of the Invention [Problem to be solved by the invention]

[0006] The above-mentioned droplet diffusion prevention partition can block droplet diffusion from one side to the other side when placed on a desk. The above-mentioned droplet diffusion prevention partition has a transparent sheet portion, so that a person on one side of the droplet diffusion prevention partition can see a person on the other side. However, because the droplet diffusion prevention partition blocks sound, a problem may occur in that a person on one side of the droplet diffusion prevention partition has difficulty hearing the voice or sound of a person on the other side.

[0007] The present disclosure aims to provide a droplet suppression member that can block droplets while making it easier to hear people's voices and sounds. [Means for solving the problem]

[0008] The splash prevention member according to the present disclosure includes a visual recognition portion made of a transparent member that blocks splashes, a sound transmitting portion that blocks splashes and transmits sound, and a support portion that supports the visual recognition portion and the sound transmitting portion as a unit. The support portion has a first support portion that supports the sound transmitting portion, the first support portion has a first fixed portion to which the sound transmitting portion is fixed and a second fixed portion fixed to the first fixed portion, the first fixed portion has a first opening that the sound transmitting portion faces, and the second fixed portion has a second opening that exposes the sound transmitting portion, and the sound transmitting portion is supported by the support portion in a state where the sound transmitting portion is sandwiched between the first fixed portion and the second fixed portion. do.

[0009] In this splash suppression member, the visual recognition portion is made of a transparent material that blocks splashes. Therefore, a person on one side as viewed from the visual recognition portion can see a person on the opposite side. Since the visual recognition portion is made of a transparent material that blocks splashes, the visual recognition portion can prevent the spread of splashes. The splash suppression member has a sound transmitting portion, which blocks splashes and passes sound. Therefore, the sound transmitting portion can prevent the spread of splashes. Furthermore, when a person on one side as viewed from the sound transmitting portion speaks, the voice passes through the sound transmitting portion, making it easier for a person on the opposite side as viewed from the sound transmitting portion to hear the voice. The splash suppression member has a support portion that supports the visual recognition portion and the sound transmitting portion as a whole. Therefore, since the support portion supports the visual recognition portion and the sound transmitting portion as a whole, a single splash suppression member can be used to visually recognize people while suppressing the spread of splashes, and to easily hear people's voices and sounds.

[0010] The sound transmitting portion may be located vertically below the viewing portion. In this case, by positioning the viewing portion vertically above and the sound transmitting portion vertically below, it is possible to arrange the droplet suppression member so that the viewing portion faces a person's eyes and the sound transmitting portion faces a person's mouth. This makes it possible to improve the visibility of a person on one side of the droplet suppression member and a person on the other side of the droplet suppression member while making it easier to hear voices and sounds.

[0011] The sound transmitting portion may be detachable from the support portion. In this case, even if the sound transmitting portion deteriorates due to long-term use, the sound transmitting portion can be replaced. This makes it possible to make the sound transmitting portion more hygienic.

[0012] The splash control member may include a stand that holds the support part in a self-supporting state. In this case, the support part that integrally supports the visual recognition part and the sound transmitting part can be made to stand by the stand. Therefore, by making the support part stand by the stand, the splash control member can be placed in any position, making it easier to use and easier to handle.

[0013] The support part is , visual Second Supporter in Support of the Recognition Department Department Including good The first fixing portion may have a convex portion on which the sound transmitting portion is placed and against which the second fixing portion abuts via the placed sound transmitting portion. In this case, the first support portion that supports the sound transmitting portion includes the first fixing portion on which the sound transmitting portion is placed and the second fixing portion that sandwiches the sound transmitting portion together with the first fixing portion. Therefore, the sound transmitting portion is supported in a state where it is sandwiched between the first fixing portion and the second fixing portion, so that it is possible to suppress the sound transmitting portion from falling and being displaced. Furthermore, the first fixing portion has a convex portion on which the second fixing portion abuts via the placed sound transmitting portion. Therefore, the sound transmitting portion placed on the convex portion abuts against the second fixing portion, so that it is possible to firmly support the sound transmitting portion. In addition, the convex portion can simplify the configuration for sandwiching and supporting the sound transmitting portion, so that it is possible to reduce the cost of the configuration for sandwiching and supporting the sound transmitting portion.

[0014] The second fixing portion may be integral with the second supporting portion. In this case, the second fixing portion that abuts against the sound transmitting portion and the convex portion is integral with the second supporting portion that supports the visual confirmation portion. Therefore, since the second fixing portion is integral with the second supporting portion, the elasticity of the second fixing portion is increased, and the abutment force of the second fixing portion against the sound transmitting portion and the convex portion can be increased. Therefore, the sound transmitting portion can be supported more firmly. Effect of the Invention

[0017] Hereinafter, an embodiment of the splash suppression member according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are given the same reference numerals, and duplicated descriptions are omitted as appropriate. In addition, the drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional ratios and the like are not limited to those shown in the drawings.

[0018] The splash prevention member according to the embodiment includes a visual recognition portion made of a transparent member that blocks splashes. In this disclosure, "splashes" refers to minute droplets that scatter. "Splash prevention" includes suppressing splashes, blocking splashes, and preventing splashes.

[0019] "Transparent member" refers to a transparent member or a transparent portion. "Transparent" refers to the property of transmitting light and being see-through. "Transparent" may be colorless and transparent, colored and transparent, or translucent. "Viewing portion" refers to a portion or member through which the other side of the viewing portion can be seen (a portion or member through which the other side of the viewing portion can be seen from one side of the viewing portion).

[0020] The splash control member has a sound passing portion that blocks splashes and passes sound. "Sound" refers to the vibration of gas. "Sound passing portion" refers to a part or member that passes sound. "Sound passing portion" refers to a part or member that passes sound to the other side of the sound passing portion (a part or member that can pass sound from one side of the sound passing portion to the other side of the sound passing portion). The splash control member has a support portion that supports the visual portion and the sound passing portion as a single unit. "As a single unit" refers to a state in which multiple objects are supported as if they were integrated. "Support" refers to supporting and holding, and "support portion" refers to a part or member that can be supported and held.

[0021] (First embodiment) Fig. 1 is a perspective view showing a splash prevention member 1 according to an exemplary embodiment 1. As shown in Fig. 1, the splash prevention member 1 includes a plate-shaped support part 10, a stand part 20 that enables the support part 10 to stand on its own, a visual confirmation part 30 that is a transparent member supported by the support part 10, and a sound transmitting part 40 that is supported by the support part 10 and allows sound to pass through.

[0022] The support section 10, the stand section 20, the visual confirmation section 30, and the sound transmitting section 40 are made of, for example, lightweight materials. Therefore, it is possible to make the splash prevention member 1 light enough to be easily carried with one hand. In addition, the support section 10, the stand section 20, the visual confirmation section 30, and the sound transmitting section 40 are made of unbreakable materials. Therefore, even if the splash prevention member 1 is dropped, it is possible to prevent the splash prevention member 1 from being damaged.

[0023] The droplet prevention member 1 is, for example, plate-shaped. The droplet prevention member 1 is visible from one side to the other side in a first direction D1, which is the plate thickness direction of the droplet prevention member 1, and is sound-passable from one side to the other side of the first direction D1. The support portion 10 is, for example, frame-shaped. The visual portion 30 and the sound-passing portion 40 are aligned along a second direction D2 that intersects (for example, perpendicular to) the first direction D1. The second direction D2 is, for example, a vertical direction.

[0024] The splash prevention member 1 includes, for example, a plurality of (for example, two) stand portions 20. This allows the support portion 10 to be stabilized by the plurality of stand portions 20. For example, the plurality of stand portions 20 are lined up along the third direction D3. The third direction D3 is a direction that intersects (for example, perpendicular to) both the first direction D1 and the second direction D2.

[0025] For example, the height of the lower end of the support part 10 (first support part 11 described later) is higher than the height of the lower end of the stand part 20 (lower bottom part 22 described later). In this case, when the splash prevention member 1 is placed on a desk or table, etc., it is possible to form a (small) gap between the upper surface of the desk or table, etc. and the lower end of the support part 10. This allows the splash prevention member 1 to be placed on a surface that is not flat but has irregularities. However, the height of the lower end of the support part 10 can be appropriately changed, for example, depending on the degree of the cut into the attached part 16 or the detachable part 25 described later. For example, the height of the lower end of the support part 10 may be the same as the height of the lower end of the stand part 20. In this case, when the support part 10 is placed on a desk or table, etc., the lower end of the support part 10 can be brought into contact with the horizontal upper surface of the desk or table, etc.

[0026] Fig. 2 is a front view of the splash prevention member 1 when the splash prevention member 1 is viewed along the first direction D1. Fig. 3 is a cross-sectional view taken along line AA in Fig. 2. For example, the visual confirmation unit 30 is provided vertically above the sound transmitting unit 40. The support unit 10 has, for example, a rectangular shape with rounded corners. In this case, since the support unit 10 has rounded corners, the corners of the support unit 10 can be made less susceptible to damage.

[0027] For example, the length N of the support part 10 in the third direction D3 is 50 cm or more and 150 cm or less (110 cm as an example). However, the value of the length N is not particularly limited. The visual confirmation part 30 and the sound transmitting part 40 are, for example, quadrangular in shape with rounded corners (as an example, rectangular in shape with long sides extending along the third direction D3).

[0028] The area of ​​the visual confirmation portion 30 (the area in a plane extending in both the second direction D2 and the third direction D3) is, for example, larger than the area of ​​the sound transmitting portion 40. When the area of ​​the visual confirmation portion 30 located above the sound transmitting portion 40 is larger than the area of ​​the sound transmitting portion 40 in this manner, the field of view of a person through the visual confirmation portion 30 can be further improved.

[0029] That is, it is possible to make the face of a person on the other side of the splash prevention member 1 (visualization section 30) clearly visible. For example, the length L1 of the visualization section 30 in the second direction D2 is longer than the length L2 of the sound transmitting section 40 in the second direction D2, and the length L3 of the visualization section 30 in the third direction D3 is longer than the length L4 of the sound transmitting section 40 in the third direction D3.

[0030] The visual confirmation section 30 has, for example, antiviral properties. "Antiviral properties" refers to the property of blocking viruses and not allowing them to penetrate. The visual confirmation section 30 is made of, for example, an antiviral film (antiviral film). That is, the visual confirmation section 30 is subjected to an antiviral treatment.

[0031] The visual confirmation portion 30 is made of, for example, a material that will not break even if an impact is applied. As an example, the visual confirmation portion 30 is made of PVC (polyvinyl chloride). However, the material of the visual confirmation portion 30 may be, for example, acrylic, and is not particularly limited. The visual confirmation portion 30 is made of a transparent material. The visual confirmation portion 30 is, for example, colorless and transparent. However, the visual confirmation portion 30 may be colored and transparent, or may be translucent. However, when the visual confirmation portion 30 is colorless and transparent, the visibility to the other side of the visual confirmation portion 30 can be further improved.

[0032] As an example, the visual confirmation portion 30 has a sheet shape. The thickness of the visual confirmation portion 30 (length in the first direction D1) is, for example, 0.1 mm or more and 1 mm or less. The thickness of the visual confirmation portion 30 may be 0.2 mm or more or 0.3 mm or more, and may be 0.7 mm or less or 0.5 mm or less. As an example, the thickness of the visual confirmation portion 30 is 0.2 mm. The visual confirmation portion 30 configured as above allows the visual confirmation portion 30 to be thin and lightweight.

[0033] The stand unit 20 is, for example, detachable from the support unit 10. The stand unit 20 is attached to one end 10b and the other end 10c of the support unit 10 in the third direction D3. The stand unit 20 is, for example, plate-shaped. The stand unit 20 has main surfaces 21 on both sides, which extend along the in-plane direction of the stand unit 20, and is attached to the support unit 10 with the main surfaces 21 extending in both the first direction D1 and the second direction D2.

[0034] The main surface 21 has a trapezoidal shape, for example. The stand unit 20 is fixed to the support unit 10 so that the main surface 21 extends in a direction intersecting the support unit 10 (for example, a direction extending in both the first direction D1 and the second direction D2), whereby the stand unit 20 can more reliably support the support unit 10.

[0035] The stand portion 20 is attached to the support portion 10 so that the width of the main surface 21 expands downward. In this way, by attaching the stand portion 20 to the support portion 10 so that the width of the main surface 21 expands downward, the support portion 10 can stand independently more stably.

[0036] The stand portion 20 has a lower bottom portion 22, a pair of legs 23 extending obliquely upward from one end and the other end of the lower bottom portion 22, and an upper bottom portion 24 connecting the upper ends of the pair of legs 23. The stand portion 20 has, for example, a curved portion 26 located between the lower bottom portion 22 and the legs 23. Providing the curved portion 26 in the stand portion 20 makes it possible to make the stand portion 20 less susceptible to damage even when an impact is applied to the stand portion 20.

[0037] The stand unit 20 includes, for example, a removable portion 25 that is attached to the support unit 10. As an example, the removable portion 25 is concave. For example, the removable portion 25 is recessed from the upper bottom portion 24, and the support unit 10 is sandwiched in the recessed portion of the removable portion 25, thereby attaching the stand unit 20 to the support unit 10. As an example, the stand unit 20 is made of nonwoven fabric. In this case, the stand unit 20 can be made of a lightweight material that is light and safe. However, the stand unit 20 may be made of, for example, paper, and the material of the stand unit 20 is not particularly limited.

[0038] The support section 10 functions, for example, as a frame for the visual confirmation section 30 and the sound transmitting section 40. That is, the visual confirmation section 30 and the sound transmitting section 40 are supported inside the support section 10. The support section 10 is made of a nonwoven fabric, for example. The support section 10 may be made of a needle punch frame. The support section 10 may be made of the same material as the stand section 20, for example. In this case, the support section 10 can be made of a lightweight material that is light and safe.

[0039] The support portion 10 has, for example, a first support portion 11 that supports the sound transmitting portion 40 and a second support portion 12 that supports the visual recognition portion 30. The first support portion 11 and the second support portion 12 are, for example, frame-shaped. The first support portion 11 and the second support portion 12 are, for example, aligned along the second direction D2, and the second support portion 12 is provided vertically above the first support portion 11.

[0040] The support portion 10 (second support portion 12) includes, for example, a first portion 13 and a second portion 14 aligned along a first direction D1. The visual confirmation portion 30 is supported by the support portion 10 in a state where it is sandwiched between the first portion 13 and the second portion 14. The first portion 13 and the second portion 14 are each frame-shaped when viewed along the first direction D1.

[0041] Fig. 4 is an enlarged side view of the first portion 13 and the second portion 14. As shown in Figs. 3 and 4, the support portion 10 (second support portion 12) includes a frame-shaped reinforcing cloth 12b sandwiched between the first portion 13 and the second portion 14. The strength of the support portion 10 is increased by interposing the reinforcing cloth 12b between the first portion 13 and the second portion 14. The reinforcing cloth 12b is, for example, in a mesh shape. The reinforcing cloth 12b is adhered to at least one of the first portion 13 and the second portion 14 by an adhesive.

[0042] The splash prevention member 1 configured as above may be distributed as a splash prevention kit 50, for example, as shown in Fig. 5. The splash prevention kit 50 includes a support part 10 that supports the above-mentioned visual part 30 and sound transmitting part 40, and a stand part 20. In the splash prevention kit 50, for example, the stand part 20 is separate from the support part 10.

[0043] As an example, in the splash prevention kit 50, the stand unit 20 is arranged so that the main surface 21 is aligned along both the second direction D2 and the third direction D3. This allows the entire splash prevention kit 50 to be arranged to extend in a plane in both the second direction D2 and the third direction D3, making it possible to make the splash prevention kit 50 easy to carry.

[0044] The support part 10 includes a mounting part 16 to which the stand part 20 is attached. The support part 10 includes a plurality of mounting parts 16 (for example, two) arranged along the third direction D3, for example. For example, the mounting part 16 has a slit shape into which the stand part 20 is inserted. For example, the mounting part 16 has a rectangular shape recessed from the lower end of the support part 10 (first support part 11). For example, the detachable part 25 of the stand part 20 is inserted into the mounting part 16. By inserting the detachable part 25 into the mounting part 16, the stand part 20 can be attached to the support part 10.

[0045] 5, 6(a) and 6(b), the first support portion 11 has, for example, a plate-shaped first fixed portion 11b to which the sound transmitting portion 40 is fixed, and a second fixed portion 11c fixed to the first fixed portion 11b. The first support portion 11 is configured by fixing the second fixed portion 11c to the first fixed portion 11b to which the sound transmitting portion 40 is fixed.

[0046] The first fixed portion 11b has a first attached portion 16b constituting the attached portion 16, and the second fixed portion 11c has a second attached portion 16c constituting the attached portion 16. The attached portion 16 is formed by overlapping the second attached portion 16c on the first attached portion 16b along the first direction D1. The second fixed portion 11c has an opening 17 that exposes the sound transmitting portion 40.

[0047] For example, the opening 17 has a rectangular shape (e.g., a rectangular shape with rounded corners) having a long side 17b extending along the third direction D3 and a short side 17c extending along the second direction D2. The second fixed portion 11c is separable from the first fixed portion 11b and the second support portion 12. The sound transmitting portion 40 is supported by the support portion 10 in a state where the sound transmitting portion 40 is sandwiched between the first fixed portion 11b and the second fixed portion 11c.

[0048] For example, the first fixing portion 11b has a first joint portion 18b, and the second fixing portion 11c has a second joint portion 18c joined to the first joint portion 18b. As an example, the first joint portion 18b and the second joint portion 18c are configured with a hook and loop fastener. For example, one of the first joint portion 18b and the second joint portion 18c is a hook and loop fastener (male), and the other of the first joint portion 18b and the second joint portion 18c is a hook and loop fastener (female). However, the first joint portion 18b and the second joint portion 18c may be configured with something other than a hook and loop fastener, and the type and material of the first joint portion 18b and the second joint portion 18c are not particularly limited.

[0049] The first fixing portion 11b has a plurality of first joint portions 18b, and the second fixing portion 11c has a plurality of second joint portions 18c. For example, each of the first joint portions 18b and the second joint portions 18c is dot-shaped (circular, for example). The position of the first joint portion 18b in the first fixing portion 11b corresponds to the position of the second joint portion 18c in the second fixing portion 11c. This makes it possible to align and join the second fixing portion 11c to the first fixing portion 11b by joining the second joint portion 18c to the first joint portion 18b.

[0050] For example, the multiple first joints 18b are arranged to form a quadrangular shape (e.g., a rectangular shape) on the first fixed portion 11b. The first joints 18b may be arranged at each corner of the first fixed portion 11b. The example of FIG. 6(a) shows an example in which four first joints 18b arranged in a rectangular shape and two first joints 18b arranged near the center of each long side of the rectangle are provided. However, the number and arrangement of the first joints 18b are not limited to the above example and can be changed as appropriate.

[0051] 7 shows a state in which the sound transmitting portion 40 is removed from the first fixing portion 11b. As shown in FIG. 6(a) and FIG. 7, the first fixing portion 11b includes an opening 19 to which the sound transmitting portion 40 faces, and a sound transmitting portion joint portion 41 to which the sound transmitting portion 40 is joined. The opening 19 has, for example, a rectangular shape (one example is a rectangular shape with rounded corners) having a long side 19b extending along the third direction D3 and a short side 19c extending along the second direction D2. The shape of the opening 19 may be, for example, the same as or similar to the shape of the opening 17 described above.

[0052] For example, the sound transmitting portion joint 41 is made of a hook and loop fastener. As an example, the sound transmitting portion joint 41 is made of a hook and loop fastener hook (male) and is capable of adsorbing the sound transmitting portion 40. However, the sound transmitting portion joint 41 may be made of a material other than a hook and loop fastener as long as it is capable of joining the sound transmitting portion 40. The material of the sound transmitting portion joint 41 may be the same as the material of the first joint 18b or may be different from the material of the first joint 18b.

[0053] The first fixed portion 11b has, for example, a plurality of sound transmitting portion joints 41. As an example, the sound transmitting portion joints 41 are dot-shaped (or circular). The positions of the sound transmitting portion joints 41 in the first fixed portion 11b correspond to the outer shape of the sound transmitting portion 40. This makes it possible to both align and join the sound transmitting portion 40 to the first fixed portion 11b by joining the sound transmitting portion 40 to the sound transmitting portion joints 41.

[0054] For example, the multiple sound transmitting part joints 41 are arranged to form a polygonal shape (a square or hexagonal shape, for example) on the first fixed portion 11b. The multiple sound transmitting part joints 41 are arranged, for example, to surround the opening 19. This makes it possible for the multiple sound transmitting part joints 41 to attach the sound transmitting part 40 covering the opening 19 to the outside of the opening 19.

[0055] For example, the sound transmitting part joint 41 is disposed inside an area (a rectangular area, for example) surrounded by the plurality of first joints 18b. That is, the plurality of first joints 18b are disposed so as to surround the sound transmitting part joint 41. The sound transmitting part joint 41 may be disposed outside a corner of the opening 19.

[0056] For example, four sound transmitting part joints 41 arranged in a rectangular shape and two sound transmitting part joints 41 arranged near the center of each long side of the rectangle are provided on the first fixed part 11b. However, the number and arrangement of the sound transmitting part joints 41 are not limited to the above example and can be changed as appropriate.

[0057] As described above, the sound transmitting portion 40 arranged to cover the opening 19 is joined to the sound transmitting portion joint 41. Then, the second joint 18c of the second fixed portion 11c is joined to the first joint 18b of the first fixed portion 11b, whereby the second fixed portion 11c is fixed to the first fixed portion 11b, and the first support portion 11 is completed.

[0058] Fig. 8 is a diagram showing the sound transmitting portion 40. As shown in Fig. 8, for example, the sound transmitting portion 40 has a rectangular shape having a pair of long sides 40A extending in the third direction D3 and a pair of short sides 40B extending in the second direction D2. However, the shape of the sound transmitting portion 40 may be a shape other than a rectangle, and is not particularly limited.

[0059] The sound transmitting portion 40 has, for example, antiviral properties. As an example, the sound transmitting portion 40 contains at least one of a carboxylic acid and an anionic functional group. The sound transmitting portion 40 has a function of inactivating viruses while adsorbing the viruses. The sound transmitting portion 40 is made of, for example, a nonwoven fabric that has been subjected to an antiviral treatment.

[0060] The sound transmitting portion 40 may also include padding 40b and thread 40c. For example, the sound transmitting portion 40 is formed by inserting padding 40b between a plurality of sewn-in threads 40c. The sound transmitting portion 40 configured as described above has higher sound permeability than an acrylic plate and can be attached to the sound transmitting portion joint 41, which is a hook-and-loop fastener. The sound transmitting portion 40 can be removed from the sound transmitting portion joint 41 and replaced with a new sound transmitting portion 40.

[0061] Next, a method for assembling the splash prevention member 1 will be described. Below, an example of assembling the splash prevention member 1 from the splash prevention kit 50 will be described. The splash prevention member 1 is assembled, for example, by inserting the detachable portion 25 of the stand portion 20 into the mounting portion 16 of the support portion 10. By attaching the detachable portions 25 of the multiple stand portions 20 to the mounting portions 16 (the process of attaching the detachable portions of the stand portions to the mounting portions of the support portion), the splash prevention member 1 as shown in FIG. 1 can be easily completed.

[0062] Next, a method for replacing the sound transmitting portion 40 from the splash prevention member 1 will be described. First, the stand portion 20 is removed from the support portion 10 (a step of removing the stand portion). For example, the detachable portions 25 are removed from each of the multiple mounting portions 16 to separate the multiple stand portions 20 from the support portion 10. Then, the support portion 10 is disassembled (a step of disassembling the support portion).

[0063] 6(a), 6(b) and 7, the support part 10 is disassembled by separating the second fixed part 11c from the first support part 11 (first fixed part 11b) that supports the sound transmitting part 40 by sandwiching it therebetween (a step of separating the second fixed part of the first support part from the first fixed part). Then, the sound transmitting part 40 is peeled off from the sound transmitting part joint part 41 of the first fixed part 11b (a step of peeling the sound transmitting part from the first fixed part).

[0064] Thereafter, a new sound transmitting portion 40 is fixed to the sound transmitting portion joint 41 of the first fixing portion 11b (step of fixing the sound transmitting portion to the first fixing portion). After the sound transmitting portion 40 is fixed, the second fixing portion 11c is fixed to the first fixing portion 11b to assemble the first support portion 11 (step of fixing the second fixing portion to the first fixing portion). Then, the stand portion 20 is attached to the attachment portion 16 to complete the droplet prevention member 1 with the new sound transmitting portion 40 attached.

[0065] Next, the effects and advantages obtained from the splash prevention member 1 according to this embodiment will be described. As shown in Fig. 1, in the splash prevention member 1, the visual confirmation section 30 is made of a transparent material that blocks splashes. Therefore, a person on one side as viewed from the visual confirmation section 30 can see a person on the opposite side. Since the visual confirmation section 30 is made of a transparent material that blocks splashes, the visual confirmation section 30 can prevent the spread of splashes.

[0066] The splash prevention member 1 includes a sound transmitting portion 40, which blocks splashes and allows sound to pass through. Therefore, the sound transmitting portion 40 can prevent splashes from spreading. Furthermore, when a person on one side of the sound transmitting portion 40 speaks, their voice passes through the sound transmitting portion 40, making it easier for a person on the opposite side of the sound transmitting portion 40 to hear the voice.

[0067] The droplet prevention member 1 includes a support portion 10 that integrally supports the visual confirmation portion 30 and the sound transmitting portion 40. Since the support portion 10 integrally supports the visual confirmation portion 30 and the sound transmitting portion 40, a single droplet prevention member 1 can suppress the spread of droplets while allowing people to be visually confirmed and making it easier to hear people's voices and sounds.

[0068] The sound transmitting section 40 may be located vertically below the visual section 30. In this case, by positioning the visual section 30 vertically above and the sound transmitting section 40 vertically below, it is possible to arrange the droplet suppression member 1 so that the visual section 30 faces a person's eyes and the sound transmitting section 40 faces a person's mouth. That is, when the droplet suppression member 1 is placed on a desk or table, the droplet suppression member 1 can be seen as a mask placed on it. Therefore, it is possible to improve the visibility of a person on one side of the droplet suppression member 1 and a person on the other side, while making it easier to hear voices and sounds.

[0069] The sound transmitting portion 40 may be detachable from the support portion 10. That is, the sound transmitting portion 40 may be replaceable. In this case, even if the sound transmitting portion 40 deteriorates due to long-term use, the sound transmitting portion 40 can be replaced. Therefore, the sound transmitting portion 40 can be made more hygienic.

[0070] The splash control member 1 may include a stand portion 20 that holds the support portion 10 in a self-supporting state. In this case, the support portion 10 that integrally supports the visual recognition portion 30 and the sound transmitting portion 40 can be made to stand on its own by the stand portion 20. Therefore, the splash control member 1 can be held by hand and placed in any position, making it easier to use and easier to handle.

[0071] Second embodiment Next, a splash prevention member according to a second embodiment will be described. Fig. 9 shows a splash prevention member 61 according to the second embodiment. A portion of the configuration of the splash prevention member 61 according to the second embodiment is the same as a portion of the configuration of the splash prevention member 1 according to the first embodiment. Therefore, in the following, the same reference numerals are used to appropriately omit the description that overlaps with the splash prevention member 1 according to the first embodiment.

[0072] The splash prevention member 61 includes a support part 70 different from the support part 10 described above, a stand part 20 (see FIG. 1), a visual confirmation part 30, and a sound transmitting part 40. The support part 70 is made of a lightweight material like the support part 10. The support part 70 includes a first support part 71 that supports the sound transmitting part 40, and a second support part 72 that supports the visual confirmation part 30. The configuration of the second support part 72 is the same as the configuration of the second support part 12 described above, for example.

[0073] Fig. 10 is a cross-sectional view of the first support portion 71 when the first support portion 71 is cut by a plane extending in the first direction D1 and the second direction D2. As shown in Fig. 9 and 10, the first support portion 71 has, for example, a plate-shaped first fixing portion 71b to which the sound transmitting portion 40 is fixed, and a second fixing portion 71c placed on the first fixing portion 71b.

[0074] The second fixing portion 71c is, for example, integral with the second support portion 72 that supports the visual recognition portion 30. In this case, the second fixing portion 71c corresponds to a portion extending from the second support portion 72. The second fixing portion 71c extends from the second support portion 72 to the opposite side to the visual recognition portion 30 (the lower side of the erected splash suppression member 61). The second fixing portion 71c has an opening 17 that exposes the sound transmitting portion 40, and the first fixing portion 71b has an opening 19 that exposes the sound transmitting portion 40. The second fixing portion 71c can be rolled up from the first fixing portion 71b due to the elasticity of the support portion 70. The sound transmitting portion 40 is supported by the first support portion 71 in a state in which the sound transmitting portion 40 is sandwiched between the first fixing portion 71b and the second fixing portion 71c.

[0075] The first fixing portion 71b has a protrusion 75 against which the second fixing portion 71c abuts. The material of the protrusion 75 is, for example, the same as the material of the support portion 70 (or the support portion 10 described above). In this case, it is possible to use an end piece of the support portion 70 (or the support portion 10) as the protrusion 75, which contributes to further cost reduction.

[0076] The convex portion 75 is a portion that sandwiches the sound transmitting portion 40 together with the second fixing portion 71c. For example, the first fixing portion 71b does not have the first joining portion 18b described above, and the second fixing portion 71c does not have the second joining portion 18c described above. That is, the splash prevention member 61 according to the second embodiment does not have a joining means such as a hook-and-loop fastener. Therefore, the splash prevention member 61 can reduce costs compared to the splash prevention member 1 that has a joining means such as a hook-and-loop fastener.

[0077] The protruding portion 75 protrudes from an inner surface 71d of the first fixing portion 71b facing the second fixing portion 71c. The protruding portion 75 has a side surface 75b extending from the inner surface 71d in a direction intersecting the inner surface 71d, and a top surface 75c located on the opposite side of the inner surface 71d as viewed from the side surface 75b and on which the sound transmitting portion 40 is placed. The protruding portion 75 may be fixed to the inner surface 71d (adhesively fixed, for example), or may be a portion that protrudes from the inner surface 71d in advance. An example in which the protruding portion 75 is fixed to the inner surface 71d will be described below.

[0078] The height of the protrusion 75 with respect to the inner surface 71d (the thickness of the protrusion 75) is, for example, 1 mm or more and 8 mm or less. The height of the protrusion 75 may be 2 mm or more, 3 mm or more, or 4 mm or more. The height of the protrusion 75 may be 7 mm or less, 6 mm or less, or 5 mm or less. The height of the protrusion 75 may be the same as the thickness of the first fixing portion 71b. As an example, the height of the protrusion 75 and the thickness of the first fixing portion 71b may be 4 mm. The height of the protrusion 75 may be the same as the thickness of two first fixing portions 71b (8 mm, for example). However, the height of the protrusion 75 is not limited to the above examples.

[0079] The convex portion 75 is provided, for example, on the outside of the opening 19. As an example, the convex portion 75 is provided on the viewing portion 30 side as viewed from the opening 19 (above the opening 19 in the erected splash control member 61). In this case, the contact force of the second fixing portion 71c against the convex portion 75 can be made stronger than when the convex portion 75 is provided on the opposite side of the viewing portion 30 as viewed from the opening 19 (below the opening 19 in the erected splash control member 61). As a result, it is possible to more reliably suppress displacement of the sound transmitting portion 40 sandwiched between the convex portion 75 and the second fixing portion 71c.

[0080] The first fixing portion 71b has, for example, a plurality of (for example, five) protrusions 75. However, the number of protrusions 75 may be one, two, three, four, six or more, and is not particularly limited. For example, the plurality of protrusions 75 are arranged so as to be aligned along the third direction D3. The plurality of protrusions 75 may be arranged so as to be aligned along the second direction D2.

[0081] The multiple protrusions 75 may be arranged on the viewing section 30 side as viewed from the opening 19, and on the opposite side of the viewing section 30 as viewed from the opening 19. In the example of Fig. 9, three protrusions 75 are arranged on the viewing section 30 side as viewed from the opening 19, and two protrusions 75 are arranged on the opposite side of the viewing section 30 as viewed from the opening 19. Examples of the arrangement of the protrusions 75 have been described above. However, the arrangement of the protrusions 75 is not limited to the above examples and can be changed as appropriate.

[0082] FIG. 11 is an enlarged perspective view of the protruding portion 75. As shown in FIG. 9 and FIG. 11, the protruding portion 75 has, for example, a semi-cylindrical shape. In this case, the side surface 75b of the protruding portion 75 includes a curved surface 75d and a flat surface 75f that connects one end and the other end of the curved surface 75d in the circumferential direction to each other. As an example, the protruding portion 75 is arranged so that the flat surface 75f faces the visual confirmation portion 30 side (vertically upward). In this case, it is also possible to place the sound transmitting portion 40 on the flat surface 75f of the protruding portion 75 located on the opposite side (vertically downward) from the visual confirmation portion 30 as viewed from the opening 19.

[0083] In the above, the sound transmitting portion 40 having a rectangular shape has been described. However, the shape of the sound transmitting portion is not limited to a rectangular shape and can be changed as appropriate. For example, as shown in FIG. 12, the sound transmitting portion 45 may have a pair of protruding portions 45c protruding from both ends in the longitudinal direction.

[0084] For example, the sound transmitting portion 45 is a nonwoven fabric sheet, similar to the sound transmitting portion 40. The sound transmitting portion 45 includes, for example, a rectangular main body portion 45b and a pair of protruding portions 45c protruding from both ends of the main body portion 45b in the longitudinal direction. Each of the pair of protruding portions 45c is disposed on one side in the short side direction of the sound transmitting portion 45 (the upper side in the example of FIG. 12), and the positions of the pair of protruding portions 45c in the short side direction are the same.

[0085] An example of a method for assembling the sound transmitting portion 45 to the splash prevention member 61 according to the second embodiment will be described. First, as shown in Fig. 10 and Fig. 13, the second fixing portion 71c is turned up from the first fixing portion 71b, and the convex portion 75 is fixed to the inner surface 71d of the first fixing portion 71b (step of fixing the convex portion). Next, the sound transmitting portion 45 is placed on the top surface 75c of the convex portion 75 (step of placing the sound transmitting portion).

[0086] The sound transmitting portion 45 is placed so that the attached portions 16 are located at both ends of the main body portion 45b in the longitudinal direction. At this time, the sound transmitting portion 45 is placed so that the convex portion 45c and the attached portion 16 are aligned along the second direction D2. As an example, the sound transmitting portion 45 may be placed in an extended state. In this way, the sound transmitting portion 45 is arranged so that the convex portion 45c is located above the attached portion 16, so that the sound transmitting portion 45 can be supported by the first support portion 71 more firmly.

[0087] After placing the sound transmitting portion 45 on the convex portion 75, as shown in FIG. 14, the second fixed portion 71c that has been rolled up is placed on the sound transmitting portion 45, and the sound transmitting portion 45 is sandwiched between the convex portion 75 and the second fixed portion 71c (process of sandwiching the sound transmitting portion).

[0088] After the sound transmitting portion 45 is clamped, the stand portion 20 is attached to the attachment portion 16 of the first support portion 71 as shown in Fig. 15 (step of attaching the stand portion). When the stand portion 20 is attached to the attachment portion 16, the convex portion 75 and the second fixing portion 71c more firmly clamp the sound transmitting portion 45, so that it is possible to more reliably prevent the sound transmitting portion 45 from shifting or falling off. Through the above steps, the splash prevention member 61 is completed.

[0089] Next, the effects and advantages obtained from the droplet prevention member 61 according to the second embodiment will be described. The droplet prevention member 61 includes a support portion 70 that supports the visual confirmation portion 30 and the sound transmitting portion 45 as an integral unit. Since the support portion 70 supports the visual confirmation portion 30 and the sound transmitting portion 45 as an integral unit, the single droplet prevention member 61 makes it possible to visually confirm people while suppressing the spread of droplets, and to easily hear people's voices and sounds. Therefore, the same effects and advantages as those of the droplet prevention member 1 according to the first embodiment can be obtained.

[0090] 9, in the second embodiment, the support portion 70 includes a first support portion 71 that supports the sound transmitting portion 45 and a second support portion 72 that supports the visual recognition portion 30, and the first support portion 71 includes a first fixed portion 71b on which the sound transmitting portion 45 is placed, and a second fixed portion 71c that sandwiches the sound transmitting portion 45 together with the first fixed portion 71b. The first fixed portion 71b has a convex portion 75 on which the sound transmitting portion 45 is placed and against which the second fixed portion 71c abuts via the placed sound transmitting portion 45.

[0091] Therefore, the first support portion 71 that supports the sound transmitting portion 45 includes a first fixed portion 71b on which the sound transmitting portion 45 is placed, and a second fixed portion 71c that, together with the first fixed portion 71b, sandwiches the sound transmitting portion 45. Therefore, since the sound transmitting portion 45 is supported in a state where it is sandwiched between the first fixed portion 71b and the second fixed portion 71c, it is possible to prevent the sound transmitting portion 45 from falling or becoming displaced.

[0092] Furthermore, the first fixed portion 71b has a convex portion 75 against which the second fixed portion 71c abuts via the placed sound transmitting portion 45. Therefore, the second fixed portion 71c abuts against the sound transmitting portion 45 placed on the convex portion 75, so that the sound transmitting portion 45 can be firmly supported. Also, since the configuration for sandwiching and supporting the sound transmitting portion 45 can be simplified, the cost of the configuration for sandwiching and supporting the sound transmitting portion 45 can be reduced.

[0093] In this embodiment, the second fixing portion 71c is integral with the second supporting portion 72. That is, the second fixing portion 71c that abuts against the sound transmitting portion 45 and the convex portion 75 is integral with the second supporting portion 72 that supports the visualizing portion 30. Therefore, since the second fixing portion 71c is integral with the second supporting portion 72, the elasticity of the second fixing portion 71c is increased, and the abutment force of the second fixing portion 71c against the sound transmitting portion 45 and the convex portion 75 can be increased. Therefore, the sound transmitting portion 45 can be supported more firmly. The above effects can be obtained in the same way when another sound transmitting portion, such as the sound transmitting portion 40, is used instead of the sound transmitting portion 45.

[0094] The above describes the embodiment of the splash prevention member according to the present disclosure. However, the present disclosure is not limited to the above embodiment, and may be modified or applied to other things within the scope of the gist described in each claim. In other words, the shape, size, number, material, and arrangement of each part of the splash prevention member can be appropriately changed within the scope of the gist described above.

[0095] In the above embodiment, the splash prevention member 1 having two trapezoidal stand portions 20 has been described. However, the shape and number of the stand portions are not limited to those in the above embodiment and can be changed as appropriate. Also, the splash prevention member may not have a stand portion. In this case, for example, the splash prevention member may be a suspendable splash prevention member.

[0096] In the above embodiment, the splash control member 1 is described that includes one visual confirmation portion 30 provided on the upper side and one sound transmitting portion 40 provided on the lower side. However, the positions, numbers, sizes and shapes of the visual confirmation portion and the sound transmitting portion can be changed as appropriate. For example, the splash control member may include a plurality of visual confirmation portions, or a plurality of sound transmitting portions. In addition, the sound transmitting portion does not have to be detachable from the support portion, and the visual confirmation portion may be detachable from the support portion.

[0097] In the above embodiment, the second support part 12 of the support part 10 has the first part 13 and the second part 14 that sandwich the visual part 30, the first support part 11 of the support part 10 has the first fixing part 11b and the second fixing part 11c, and the splash prevention member 1 in which the sound transmitting part 40 is sandwiched between the first fixing part 11b and the second fixing part 11c has been described. However, the configuration of the support part that supports the visual part and the sound transmitting part is not limited to the above-mentioned support part 10 and can be appropriately changed. Also, in the above embodiment, an example in which the visual part 30 and the sound transmitting part 40 are antiviral has been described. However, at least one of the visual part 30 and the sound transmitting part 40 does not have to be antiviral. That is, it is also possible to use a part that does not have antiviral properties as the visual part and the sound transmitting part according to the present disclosure. As an example, the visual part 30 may be made of polycarbonate. In this case, the transparency of the visual part 30 can be increased, and the strength of the visual part 30 relative to its thickness can be increased.

[0098] In the above-described second embodiment, the semi-cylindrical convex portion 75 has been described. However, the shape of the convex portion provided on the first fixing portion 71b is not limited to a semi-cylindrical shape and can be changed as appropriate. Also, in the second embodiment, an example has been described in which the material of the convex portion 75 is the same as the material of the support portion 70. However, the material of the convex portion 75 may be a material different from that of the support portion 70 and can be changed as appropriate.

[0099] 16(a) and 16(b) show modified examples of the protrusions provided on the support portion 70. As shown in FIG. 16(a), the support portion 70 may include a protrusion 85 made of silicon instead of the protrusion 75 made of the same material as the support portion 70. The protrusion 85 has, for example, an elliptical shape extending in the third direction D3. In this case, the protrusion 85 can be made non-slip, so that the sound transmitting portion 40 can be more reliably prevented from shifting or falling off. The protrusion 85 is, for example, transparent. In this case, the design of the protrusion 85 can be improved.

[0100] In the example of Fig. 16(a), a plurality of (for example, three) protrusions 85 aligned in the third direction D3 are aligned on the first fixing portion 71b, and the protrusions 85 are arranged on both one side and the other side in the second direction D2 as viewed from the opening 19. However, as shown in Fig. 16(b), the protrusions 85 may be arranged only on one side in the second direction D2 as viewed from the opening 19 (the side of the visual recognition portion 30 as an example). As described above, the shape, size, number, material and arrangement of the protrusions provided on the first fixing portion 71b can be changed as appropriate.

[0101] (Example) In the following, examples of the splash prevention member according to the present disclosure will be described. Note that the present invention is not limited to the contents of the following examples. In the examples, an experiment was conducted to verify sound transmission using the sound transmitting portion 40 according to the following Example 1 and the sound transmitting portion 40 according to the following Example 2. Example 1 As the sound transmitting portion 40, Flexknit (registered trademark, Nishikawa Rose Co., Ltd.), which is a composite material combining nonwoven fabric and warp knitting (vertical weave), was used. Example 2 As the sound transmitting portion 40, a PVC sheet was used.

[0102] A sound source was placed on one side in the plate thickness direction of the sound transmitting portion 40 as viewed from the sound transmitting portion 40 according to Example 1 and the sound transmitting portion 40 according to Example 2, and a measuring device was placed on the other side. White noise was generated from the sound source, and the volume of the sound that passed through the sound transmitting portion 40 was measured by soundography with the measuring device.

[0103] As a result of the above measurements, the volume of the sound that passed through the sound transmitting portion 40 according to Example 2 was 11.7 dB, whereas the volume of the sound that passed through the sound transmitting portion 40 according to Example 1 was 56.8 dB. Therefore, it was found that the sound transmitting portion 40 which is a composite material combining nonwoven fabric and warp knitting can obtain higher sound transmission properties compared to the sound transmitting portion 40 made of PVC.
