Description

[Technical field]

[0001] The present invention relates to a basket mounting member and a basket mounting member set. [Background technology]

[0002] For example, Patent Document 1 discloses a basket for housing shellfish such as oysters. This basket is used, for example, when cultivating oysters. The basket is provided with a cylindrical support bracket that extends in a predetermined direction. A long cable is inserted into the support bracket. The basket is attached to the cable via the support bracket.

[0003] When cultivating oysters, a plurality of baskets containing oysters are prepared. In each of the plurality of baskets, a cable is inserted into a support bracket, and the baskets are supported by the cable while being aligned in a predetermined direction. The baskets are configured to be rotatable around the axis of the cable via the support bracket. When cultivating oysters, the baskets are placed on the sea and rotated periodically to promote the growth of the oysters. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 7105506 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the invention disclosed in Patent Document 1, when attaching the basket to the cable, the cable must be inserted into the support bracket, and when removing the basket from the cable, the cable must be pulled out from the support bracket. In other words, when attaching or removing the basket to or from the cable, it was necessary to remove one end of the cable that had been attached at a desired position from the desired position. Therefore, the workability of attaching and removing the basket was poor.

[0006] It should be noted that these problems are not limited to problems with cages such as baskets used for cultivating shellfish such as oysters and used in seawater, but may also be problems with cages used for organisms other than shellfish, cages used for purposes other than cultivating, cages used in freshwater, or cages used on land, and any cage that can be attached to a long connecting member such as a long cable will have similar problems.

[0007] The present invention has been made in consideration of these points, and its object is to provide a cage mounting member and a cage mounting member set that allow a cage to be easily attached and detached from a long connecting elongated member. [Means for solving the problem]

[0008] The cage mounting member according to the present invention is a cage mounting member for mounting a cage to a long connecting elongated member. The cage mounting member includes a support part for supporting the cage, and a cover part that is detachably provided on the support part and arranged to surround the connecting elongated member together with the support part.

[0009] According to the cage mounting member, the cage can be mounted to the connecting elongated member by attaching the cover part to the support part so as to surround the connecting elongated member together with the support part in a state in which the cage is supported. When the cage is mounted to the connecting elongated member, the cover part can be removed from the support part to remove the cage from the connecting elongated member. Thus, the cage can be easily mounted to and removed from the connecting elongated member by attaching and removing the cover part to and from the support part.

[0010] According to a preferred embodiment of the present invention, the support portion includes a support body extending in a first direction and formed of a flexible member, a first insertion portion provided at one end of the support body in the first direction and inserted into the cage, and a second insertion portion provided at the other end of the support body in the first direction and inserted into the cage.

[0011] According to the above aspect, the cage can be easily supported by the support portion by inserting the first insertion portion and the second insertion portion into the cage while bending the support body.

[0012] According to another preferred embodiment of the present invention, the first insertion portion and the second insertion portion each have a tapered shape that narrows in width toward a tip end.

[0013] According to the above aspect, by inserting the tapered portion into the basket first, it is possible to make it easier to insert the first insertion portion and the second insertion portion into the basket.

[0014] According to another preferred embodiment of the present invention, the first insertion portion and the second insertion portion each have a recess into which a part of the cage fits when the first insertion portion and the second insertion portion are inserted into the cage.

[0015] According to the above aspect, by fitting a part of the cage into the recesses of the first insertion portion and the second insertion portion, it is possible to make it difficult for the cage to move relative to the support portion.

[0016] According to another preferred aspect of the present invention, the support portion has a support leg that extends from the support body toward the cage and contacts the cage.

[0017] According to the above aspect, since the basket can be supported by the first insertion portion, the second insertion portion, and the support leg, the support portion can stably support the basket.

[0018] According to another preferred aspect of the present invention, the cover portion extends in the first direction and is configured to restrict bending of the support body of the support portion when attached to the support portion.

[0019] According to the above aspect, by attaching the cover portion to the support portion, the support body of the support portion can be made less likely to bend.

[0020] According to another preferred embodiment of the present invention, the support portion has a first slide protrusion provided at one end of the support body in a second direction intersecting the first direction and extending in the first direction, and a second slide protrusion provided at the other end of the support body in the second direction and extending in the first direction so as to face the first slide protrusion. A first slide groove extending in the first direction is formed on the second slide protrusion side of the first slide protrusion. A second slide groove extending in the first direction is formed on the first slide protrusion side of the second slide protrusion. The cover portion has a cover body, a first engagement flange, and a second engagement flange. The cover body extends in the first direction and is recessed in a direction away from the support portion so that the connecting elongated member can enter. The first engagement flange is provided at an end of the cover body on the support portion side and at one end in the second direction, and engages with the first slide groove. The second engagement flange is provided at an end of the cover body on the support portion side and at the other end in the second direction, and engages with the second slide groove.

[0021] According to the above aspect, by engaging the first engagement flange and the second engagement flange of the cover portion with the first slide groove and the second slide groove, respectively, the cover portion can regulate the bending of the support portion.

[0022] According to another preferred aspect of the present invention, the support portion is provided so as to protrude from the support body, extends in the first direction, and has a mounting portion on which the connected elongated member can be mounted.

[0023] According to the above aspect, by attaching the cover part to the support part with the connected elongated members placed on the placement part, it is possible to attach the cover part to the support part while determining the position of the connected elongated members.

[0024] According to another preferred embodiment of the present invention, the connected elongated member is a member extending in the first direction and having a cylindrical outer periphery, and the mounting portion has a mounting concave surface that is recessed along an outer periphery of the connected elongated member.

[0025] According to the above aspect, by placing the connected elongated member on the mounting concave surface having a shape that follows the outer circumferential shape of the connected elongated member, it is possible to easily position the connected elongated member relative to the support portion.

[0026] According to another preferred embodiment of the present invention, the support portion has a first regulating portion provided at one end of the first slide groove in the first direction and at one end of the second slide groove in the first direction, and a second regulating portion provided at the other end of the first slide groove in the first direction and at the other end of the second slide groove in the first direction. The cover portion has a first cover member, a second cover member, and a third cover member. The first cover member and the second cover member are slidable in the first slide groove and the second slide groove. The third cover member is provided in a gap between the first regulating portion and the second regulating portion when the first cover member and the second cover member are attached to the support portion, and fixes the positions of the first cover member and the second cover member in the first direction. Any one of the first cover member, the second cover member, and the third cover member comes into contact with the first regulating portion to be regulated from moving toward the first regulating portion. Any other one of the first cover member, the second cover member, and the third cover member comes into contact with the second restriction portion and is restricted from moving toward the second restriction portion.

[0027] According to the above aspect, after the first cover member and the second cover member are attached to the support portion, the third cover member can be inserted into the gap between the first regulating portion and the second regulating portion, making it difficult for the cover portions to move in the first direction relative to the support portion.

[0028] According to another preferred aspect of the present invention, the cover portion has an attachment portion that is attached to the connecting elongated member when the cover portion is detached from the support portion.

[0029] According to the above aspect, when the cover portion is detached from the support portion, the cover portion can be attached to the connecting elongated member by the attachment portion, making it possible to prevent the cover portion from falling off.

[0030] According to another preferred aspect of the present invention, the cover portion has a cover body extending in the first direction and recessed in a direction away from the support portion so that the connecting elongated member can be inserted therein. The attachment portion is provided on an inner circumferential surface of the cover body.

[0031] According to the above aspect, since the mounting portion is provided inside the cover body, the mounting portion is less likely to get caught on an external object or the like.

[0032] According to another preferred embodiment of the present invention, the connecting elongated member is a member having a cylindrical outer periphery extending in the first direction, and the mounting portion has a pair of mounting flanges extending inward from an inner periphery of the cover body along a circumferential direction of the connecting elongated member and aligned in a second direction intersecting the first direction so as to sandwich the connecting elongated member therebetween.

[0033] According to the above aspect, by sandwiching the connecting elongated member between the pair of mounting flanges, it is possible to attach the cover portion to the connecting elongated member.

[0034] The basket mounting member set of the present invention comprises any of the mounting members described above, a basket supported by the support portion of the mounting member, and a long connecting elongated member to which the basket is attached via the mounting member.

[0035] According to the above basket mounting member set, it is possible to provide a mounting member set including any one of the above mounting members, a basket, and a connecting elongated member.

[0036] According to a preferred embodiment of the present invention, the connecting elongated member extends in a first direction. A plurality of the mounting members are provided on the connecting elongated member and aligned in the first direction. A plurality of the cages are attached to the mounting members and aligned in the first direction.

[0037] According to the above aspect, the baskets can be individually removed from the connecting elongated members by removing the cover portion of the mounting member from the support portion. Effect of the Invention

The second direction D2 is the front-back direction. The third direction D3 is the up-down direction. However, these directions are merely defined for the convenience of explanation, and do not limit the installation mode of the mounting member set 1, nor do they limit the present invention.

[0042] As shown in FIG. 2, in the attachment member set 1 for the cage 10, the cage 10 is attached to the connected long member 20. In this embodiment, the attachment member set 1 is used when cultivating oysters. Here, the attachment member set 1 is used for the so-called single seed method among the methods used in cultivating oysters. As shown in FIG. 1, the attachment member set 1 can be used when attaching multiple cages 10 to the connected long member 20. The attachment member set 1 is used in seawater where oysters are cultivated. In this embodiment, as shown in FIG. 2, the attachment member set 1 includes the cage 10, the connected long member 20, and an attachment member 100 for the cage 10 (hereinafter, also simply referred to as the "attachment member 100").

[0043] Although not shown in the figure, the cage 10 contains a number of oysters. These oysters are for cultivation. The oysters are cultivated while contained in the cage 10, and when a predetermined time arrives, the oysters are removed from the cage 10 and shipped. The configuration and shape of the cage 10 are not particularly limited. In this embodiment, the cage 10 has an internal space inside, and the oysters are placed in the internal space. The cage 10 is formed of a net-like member and is configured to allow water, such as seawater, to enter the internal space.

[0044] As shown in FIG. 1, the connecting elongated member 20 is a member that connects multiple cages 10. Multiple cages 10 are attached to the connecting elongated member 20. Here, the connecting elongated member 20 is long and extends in the first direction D1. Therefore, the multiple cages 10 are attached to the connecting elongated member 20 so as to be lined up in the first direction D1. The multiple cages 10 are arranged in the first direction D1 with a predetermined interval between them. The number of cages 10 attached to the connecting elongated member 20 is not particularly limited. The number of cages 10 attached to the connecting elongated member 20 is determined according to the length of the connecting elongated member 20, the number of oysters to be cultivated at one time, the size of the area in which the connecting elongated member 20 can be installed, and the like.

[0045] In addition, the type, shape, material, etc. of the connecting elongated member 20 are not particularly limited. In this embodiment, the connecting elongated member 20 is a member having a cylindrical outer circumferential shape. For example, the connecting elongated member 20 is formed by a cylindrical pipe extending in the first direction D1, and has a space penetrating in the first direction D1 inside. However, the connecting elongated member 20 may not have a space inside and may be solid. In addition, the connecting elongated member 20 may be any member that is long (for example, extending in the first direction D1), and may be, for example, string-like. In this embodiment, the connecting elongated member 20 is formed of resin. However, the connecting elongated member 20 may be formed of, for example, metal.

[0046] Next, the mounting member 100 for the basket 10 will be described. As shown in Fig. 2, the mounting member 100 is for mounting the basket 10 containing oysters to the long connected elongated member 20. This allows the basket 10 to be mounted to the connected elongated member 20 via the mounting member 100. Here, as shown in Fig. 1, one basket 10 is mounted per one mounting member 100. A plurality of mounting members 100 are provided on the connected elongated member 20, lined up in the first direction D1.

As shown in FIG. 7, the mounting part 55 is a portion on which the connected elongated member 20 can be mounted when the attachment member 100 is attached to the connected elongated member 20. Although the connected elongated member 20 is depicted as floating from the mounting part 55 in FIG. 7, in reality, the connected elongated member 20 can be mounted on the mounting part 55. Here, the connected elongated member 20 can be mounted on the mounting part 55 depending on the rotational position of the attachment member 100 relative to the connected elongated member 20. For example, in a state where the mounting part 55 is disposed at a position below the connected elongated member 20, the connected elongated member 20 can be mounted on the mounting part 55. The mounting part 55 is provided so as to protrude from the support body 31. Here, the mounting part 55 is provided on the upper surface of the support body 31 and protrudes upward from the upper surface. In other words, the mounting portion 55 protrudes from the surface of the support body 31 facing the connected elongated member 20 toward the connected elongated member 20. The mounting portion 55 extends in the first direction D1.

[0061] As shown in FIG. 7, the mounting portion 55 has a mounting concave surface 56. The mounting concave surface 56 is a surface of the mounting portion 55 on which the connected elongated member 20 can be directly placed. Here, the mounting concave surface 56 is formed on the upper surface of the mounting portion 55 (here, the surface on the connected elongated member 20 side). The mounting concave surface 56 is a surface that is concave along the outer circumferential surface of the connected elongated member 20. Here, the mounting concave surface 56 is concave downward, and its cross-sectional shape when viewed from the first direction D1 is U-shaped. The mounting concave surface 56 is concave in a curved shape.

[0062] In this embodiment, as shown in FIG. 8, the mounting portion 55 extending in the first direction D1 is not continuous over the entire area from the left end to the right end of the support body 31, but is partially omitted and formed intermittently. Here, the mounting portion 55 is provided with a mounting unformed portion 55a that is not convex from the support body 31. The mounting unformed portion 55a is a portion that does not protrude upward from the support body 31 and is a portion where the mounting portion 55 is not formed. The upper surface of the support body 31 is exposed in the mounting unformed portion 55a. Here, the mounting unformed portion 55a is provided in the center portion of the support body 31 in the first direction D1. The number of the mounting unformed portions 55a is not particularly limited. In this embodiment, the number of the mounting unformed portions 55a is three. The three mounting unformed portions 55a are provided in the center portion of the support body 31 in the first direction D1. The size of the three mounting unformed portions 55a is not particularly limited, and may be the same size or different sizes. In this embodiment, the leftmost mounted unformed portion 55a and the rightmost mounted unformed portion 55a have the same length in the first direction D1. The central mounted unformed portion 55a has a shorter length in the first direction D1 than the left and right mounted unformed portions 55a. In this manner, in this embodiment, since three mounted unformed portions 55a are provided on the support body 31, the mounting portion 55 is divided into four portions.

[0063] In this embodiment, by providing the support body 31 with the unformed mounting portion 55a, the thickness of the portion of the support body 31 where the unformed mounting portion 55a is provided becomes relatively small, which makes it easier to bend the support body 31. Here, the unformed mounting portion 55a is provided in the center portion of the support body 31 in the first direction D1, which makes it easier for the support body 31 to bend in the center portion.

[0064] In this embodiment, as shown in FIG. 8, the support portion 30 has a first slide protrusion 61 and a second slide protrusion 62. The first slide protrusion 61 and the second slide protrusion 62 are provided on the support body 31 and extend in the first direction D1. The first slide protrusion 61 and the second slide protrusion 62 are provided on the surface of the support body 31 on which the mounting portion 55 is provided. Here, the first slide protrusion 61 and the second slide protrusion 62 are provided on the upper surface of the support body 31 and protrude upward from the upper surface. In this embodiment, as shown in FIG. 7, the mounting portion 55 protrudes upward from the first slide protrusion 61 and the second slide protrusion 62. The first slide protrusion 61 is provided at one end (here, the front end) of the support body 31 in the second direction D2. The second slide protrusion 62 is disposed behind the first slide protrusion 61 and is provided at the other end (here, the rear end) of the support body 31 in the second direction D2. The second slide protrusion 62 faces the first slide protrusion 61. As shown in FIG. 8, the first slide protrusion 61 and the second slide protrusion 62 are provided at positions where they overlap in the first direction D1. The first slide protrusion 61 and the second slide protrusion 62 are provided from the left end to the right end of the support body 31. Here, as shown in FIG. 7, a mounting portion 55 is provided between the first slide protrusion 61 and the second slide protrusion 62. The first slide protrusion 61 faces the second slide protrusion 62 with the mounting portion 55 interposed therebetween.

[0065] In this embodiment, a first slide groove 63 is formed in the first slide protrusion 61. The first slide groove 63 is a groove extending in the first direction D1. Here, the first slide groove 63 is formed on the second slide protrusion 62 side of the first slide protrusion 61 (in this embodiment, the rear surface). Similarly, a second slide groove 64 is formed in the second slide protrusion 62. The second slide groove 64 is a groove extending in the first direction D1. Here, the second slide groove 64 is formed on the first slide protrusion 61 side of the second slide protrusion 62 (in this embodiment, the front surface). The second slide groove 64 faces the first slide groove 63.

[0066] In this embodiment, as shown in FIG. 8, a first front restricting portion 65 is provided at one end (here, the left end) of the first slide groove 63 in the first direction D1. A first rear restricting portion 66 is provided at one end (here, the left end) of the second slide groove 64 in the first direction D1. A second front restricting portion 67 is provided at the other end (here, the right end) of the first slide groove 63 in the first direction D1. A second rear restricting portion 68 is provided at the other end (here, the right end) of the second slide groove 64 in the first direction D1. In this embodiment, the first front restricting portion 65 and the first rear restricting portion 66 are examples of the first restricting portion of the present invention, and the second front restricting portion 67 and the second rear restricting portion 68 are examples of the second restricting portion of the present invention.

[0067] The first slide groove 63 is formed between the first front restricting portion 65 and the second front restricting portion 67. The first front restricting portion 65 is provided at the left end of the first slide convex portion 61, in other words, at the left end of the support body 31. The first front restricting portion 65 is configured to close the left end of the first slide groove 63. The second front restricting portion 67 is provided at the right end of the first slide convex portion 61, in other words, at the right end of the support body 31. The second front restricting portion 67 is configured to close the right end of the first slide groove 63.

[0068] The second slide groove 64 is formed between the first rear restricting portion 66 and the second rear restricting portion 68. The first rear restricting portion 66 is provided at the left end of the second slide protrusion 62, in other words, the left end of the support body 31. The first rear restricting portion 66 is configured to close the left end of the second slide groove 64. The second rear restricting portion 68 is provided at the right end of the second slide protrusion 62, in other words, the right end of the support body 31. The second rear restricting portion 68 is configured to close the right end of the second slide groove 64.

[0069] The first slide protrusion 61 extending in the first direction D1 is not continuous over the entire area from the left end to the right end of the support body 31, but is partially omitted and formed intermittently. Similarly, the second slide protrusion 62 extending in the first direction D1 is not continuous over the entire area from the left end to the right end of the support body 31, but is partially omitted and formed intermittently. Here, the first slide protrusion 61 is provided with a first unformed portion 61a that is not convex from the support body 31. Similarly, the second slide protrusion 62 is provided with a second unformed portion 62a that is not convex from the support body 31. The first unformed portion 61a and the second unformed portion 62a are portions that do not protrude upward from the support body 31. The first unformed portion 61a is a portion where the first slide protrusion 61 and the first slide groove 63 are not formed. The second unformed portion 62a is a portion where the second slide protrusion 62 and the second slide groove 64 are not formed. In the first unformed portion 61a and the second unformed portion 62a, the upper surface of the support body 31 is exposed.

[0070] Here, the first unformed portion 61a and the second unformed portion 62a are provided in the central portion of the support body 31 in the first direction D1. The number of the first unformed portions 61a and the number of the second unformed portions 62a are not particularly limited. In this embodiment, the number of the first unformed portions 61a and the number of the second unformed portions 62a are the same, but may be different. Here, the number of the first unformed portions 61a and the number of the second unformed portions 62a are both three. The three first unformed portions 61a and the three second unformed portions 62a are provided in the central portion of the support body 31 in the first direction D1. The size of the first unformed portion 61a and the second unformed portion 62a is also not particularly limited, and the three first unformed portions 61a and the three second unformed portions 62a may be the same or different in size. Here, the first unformed portion 61a located at the leftmost and rightmost positions and the second unformed portion 62a located at the leftmost and rightmost positions have the same length in the first direction D1. The first unformed portion 61a located at the center and the second unformed portion 62a located at the center have the same length in the first direction D1. In this embodiment, the first unformed portion 61a located at the center has a longer length in the first direction D1 than the first unformed portions 61a located on both the left and right sides, but the length in the first direction D1 may be shorter. Similarly, the second unformed portion 62a located at the center has a longer length in the first direction D1 than the second unformed portions 62a located on both the left and right sides, but the length in the first direction D1 may be shorter.

[0071] Thus, in this embodiment, three first unformed portions 61a and three second unformed portions 62a are provided in the support body 31. Therefore, the first slide protrusion 61 is divided into four parts, and the second slide protrusion 62 is divided into four parts. Here, as described above, the first slide groove 63 is not formed in the first unformed portion 61a, and the second slide groove 64 is not formed in the second unformed portion 62a. Therefore, the first slide groove 63 is divided into four parts by the three first unformed portions 61a. The second slide groove 64 is divided into four parts by the three second unformed portions 62a.

[0072] In this embodiment, by providing the first unformed portion 61a and the second unformed portion 62a in the support body 31, the thickness of the portion of the support body 31 where the first unformed portion 61a and the second unformed portion 62a are provided becomes relatively small, so that the support body 31 can be easily bent. Here, the first unformed portion 61a and the second unformed portion 62a are provided in the central portion of the support body 31 in the first direction D1, so that the support body 31 can be easily bent in the central portion.

[0073] In this embodiment, as shown in FIG. 6, the region of the support body 31 where the mounting unformed portion 55a, the first unformed portion 61a, and the second unformed portion 62a are provided in the support portion 30 is called the mounting region AR11. As shown in FIG. 4, the support leg 50 is arranged in the mounting region AR11. As shown in FIG. 8, the region of the support body 31 where the mounting unformed portion 55a, the first unformed portion 61a, and the second unformed portion 62a are not provided in the support portion 30 and where the mounting portion 55, the first slide protrusion 61, and the second slide protrusion 62 are continuous with each other is called the first slide mounting region AR21 and the second slide mounting region AR22. Here, as shown in FIG. 6, the mounting region AR11, the first slide mounting region AR21, and the second slide mounting region AR22 are arranged side by side in the first direction D1. The first slide mounting region AR21 is arranged to the left of the mounting region AR11. The second slide mounting region AR22 is disposed to the right of the mounting region AR11. The mounting region AR11 is disposed between the first slide mounting region AR21 and the second slide mounting region AR22.

[0074] Next, the cover part 70 will be described. As described above, as shown in Fig. 4, the cover part 70 is arranged so as to surround the connected elongated member 20 together with the support part 30 on which the basket 10 is supported. The cover part 70 is provided so as to be detachable from the support part 30. As shown in Fig. 7, for example, in a state in which the support part 30 is arranged below the connected elongated member 20, the cover part 70 is attached to the support part 30 so as to cover the connected elongated member 20 from above.

[0075] As shown in Fig. 5, the cover portion 70 extends in a first direction D1. The cover portion 70 is configured to restrict bending of the support body 31 of the support portion 30 when attached to the support portion 30. In this embodiment, the support body 31 of the support portion 30 is formed of a flexible member, and is configured such that, for example, the central portion is easily bent. The cover portion 70 is configured to restrict bending of the support body 31 when attached to the support portion 30.

[0076] In this embodiment, as shown in Fig. 7, the cover portion 70 has a cover main body 71, a first engagement flange 75, and a second engagement flange 76. As shown in Fig. 5, the cover main body 71 extends in a first direction D1. Here, as shown in Fig. 7, the cover main body 71 is recessed in a direction away from the support portion 30 (here, upward). The upward recessed portion of the cover main body 71 extends in the first direction D1. The cross-sectional shape of the cover main body 71 when viewed from the first direction D1 is U-shaped. The cover portion 70 is configured so that the connecting elongated member 20 can fit into the recessed portion of the cover main body 71.

[0077] When the cover portion 70 is attached to the support portion 30, the cover body 71 has a first portion 71a extending upward from the first slide protrusion 61, a second portion 71b extending upward from the second slide protrusion 62, and a connecting portion 71c connecting the first portion 71a and the second portion 71b. The first portion 71a, the second portion 71b, and the connecting portion 71c are plate-shaped. The first portion 71a, the second portion 71b, and the connecting portion 71c form a U-shape.

[0078] The first engagement flange 75 is engaged with the first slide groove 63 formed in the first slide protrusion 61 of the support portion 30 so as to be slidable in the first direction D1. The first engagement flange 75 is provided at the end of the cover body 71 on the support portion 30 side, here, the lower end of the cover body 71. The first engagement flange 75 is provided at one end (here, the front end) of the cover body 71 in the second direction D2, that is, at the end of the cover body 71 on the first slide protrusion 61 side. The first engagement flange 75 is provided at the lower end of the first portion 71a of the cover body 71. The first engagement flange 75 protrudes forward from the cover body 71 and extends in the first direction D1 as shown in FIG. 6.

[0079] As shown in FIG. 7, the second engagement flange 76 is engaged with the second slide groove 64 formed in the second slide protrusion 62 of the support portion 30 so as to be slidable in the first direction D1. The second engagement flange 76 is configured to be symmetrical to the first engagement flange 75 across the cover body 71. The second engagement flange 76 is provided on the opposite side of the cover body 71 to the first engagement flange 75. Here, the second engagement flange 76 is provided on the end of the cover body 71 on the support portion 30 side (here, the lower end of the cover body 71). The second engagement flange 76 is provided on the other end of the cover body 71 in the second direction D2 (here, the rear end), that is, the end of the cover body 71 on the second slide protrusion 62 side. The second engagement flange 76 is provided on the lower end of the second portion 71b of the cover body 71. The second engagement flange 76 protrudes rearward from the cover body 71 and extends in the first direction D1 as shown in FIG. 6. The second engagement flange 76 is located at the same position as the first engagement flange 75 in the first direction D1.

[0080] In this embodiment, the cover portion 70 is flexible. The cover portion 70 is formed of a flexible material. Here, the cover portion 70 is formed of the same material as the material forming the support portion 30, and is formed of a resin, for example, a thermoplastic resin. As with the support portion 30, the thermoplastic resin forming the cover portion 70 is preferably a general-purpose plastic such as high-density polyethylene, polyvinyl chloride, or ABS resin, and among these, high-density polyethylene is particularly preferable.

[0081] In this embodiment, the cover portion 70 can be bent so that the first engaging flange 75 and the second engaging flange 76 approach each other. The cover portion 70 is attached to the support portion 30 in a state in which the first engaging flange 75 and the second engaging flange 76 are bent so that they approach each other. Here, although not shown, in a state in which the cover portion 70 is detached from the support portion 30, the distance in the second direction D2 from the first engaging flange 75 to the second engaging flange 76 is referred to as the first distance. The first distance is the maximum distance in the second direction D2 from the tip (front end here) of the first engaging flange 75 to the tip (rear end here) of the second engaging flange 76. In addition, in the support portion 30, the distance in the second direction D2 from the first slide groove 63 to the second slide groove 64 is referred to as the second distance. The second distance is the maximum distance in the second direction D2 from the front end of the first slide groove 63 to the rear end of the second slide groove 64. In this embodiment, the first distance is longer than the second distance.

[0082] Therefore, the cover part 70 is attached to the support part 30 in a bent state so that the first engagement flange 75 and the second engagement flange 76 approach each other. At this time, the first engagement flange 75 is engaged with the first slide groove 63 in a state in which an elastic force toward the first slide groove 63 is applied to the first engagement flange 75. Similarly, the second engagement flange 76 is engaged with the second slide groove 64 in a state in which an elastic force toward the second slide groove 64 is applied to the second engagement flange 76. Therefore, the elastic force can make it difficult for the cover part 70 to be detached from the support part 30.

[0083] In this embodiment, as shown in Fig. 5, the cover section 70 is composed of a plurality of members. Here, the cover section 70 has a first cover member 81, a second cover member 82, and a third cover member 83, and is composed of three members. The first cover member 81, the second cover member, and the third cover member 83 are arranged side by side in the first direction D1. Here, the first cover member 81, the third cover member 83, and the second cover member 82 are arranged side by side from the left, but the positions of the first cover member 81, the second cover member 82, and the third cover member 83 may be interchanged.

[0084] 9 and 10 are perspective views showing the first cover member 81, the second cover member 82, and the third cover member 83. FIG. 11 is a plan view showing the first cover member 81, the second cover member 82, and the third cover member 83. As shown in FIG. 9, the first cover member 81, the second cover member 82, and the third cover member 83 have the same shape and the same size. The first cover member 81, the second cover member 82, and the third cover member 83 are produced using the same mold. The first cover member 81, the second cover member 82, and the third cover member 83 all have a U-shaped cross section when viewed from the first direction D1, and each has a cover main body 71, a first engagement flange 75, and a second engagement flange 76. The length in the first direction D1 of each of the first cover member 81, the second cover member 82, and the third cover member 83 is the same, and is, for example, approximately one-third of the distance in the first direction D1 from the first front restricting portion 65 to the second front restricting portion 67 in the first slide groove 63 (in other words, the distance in the first direction D1 from the first rear restricting portion 66 to the second rear restricting portion 68 in the second slide groove 64). Therefore, as shown in FIG. 6, the first cover member 81, the second cover member 82, and the third cover member 83 engage with the first slide groove 63 and the second slide groove 64 while being aligned in the first direction D1. At this time, the movement of the first cover member 81, the second cover member 82, and the third cover member 83 in the first direction D1 is restricted by the first front restricting portion 65, the second front restricting portion 67, the first rear restricting portion 66, and the second rear restricting portion 68, so that it is difficult for them to move in the first direction D1.

[0085] In this embodiment, the cover members 81, 82, and 83 are line-symmetrical with respect to the center line of the first direction D1 (the center line extending in the third direction D3). That is, in each of the cover members 81, 82, and 83, the left and right portions of the center line in the first direction D1 have a shape that is line-symmetrical. Therefore, each of the first cover member 81, the second cover member 82, and the third cover member 83 can be attached to the support part 30 with the left and right reversed.

[0086] In this embodiment, as shown in Fig. 9, the first cover member 81, the second cover member 82, and the third cover member 83 each have an end portion (here, the left end portion and the right end portion) in the first direction D1 that is thicker toward the end. Here, as described above, the first cover member 81 to the third cover member 83 have the same configuration, so the following description will be given using the first cover member 81 as an example. In the first cover member 81, the thickness of both end portions in the first direction D1 is thicker than the thickness of the central portion in the first direction D1. Here, in the first cover member 81, the thickness is thicker toward the end portions in the first direction D1 because the first cover member 81 bulges outward from the cover main body 71.

[0087] 6, any one of the first cover member 81, the second cover member 82, and the third cover member 83 is arranged so as to contact the first front restricting portion 65 and the first rear restricting portion 66, and movement toward the first front restricting portion 65 and the first rear restricting portion 66 is restricted. Also, any other one of the first cover member 81, the second cover member 82, and the third cover member 83 is arranged so as to contact the second front restricting portion 67 and the second rear restricting portion 68, and movement toward the second front restricting portion 67 and the second rear restricting portion 68 is restricted.

[0088] In this embodiment, the first cover member 81 is disposed so as to come into contact with the first front restricting portion 65 and the first rear restricting portion 66, and movement toward the first front restricting portion 65 and the first rear restricting portion 66 is restricted. The first cover member 81 is disposed in the first slide mounting region AR21 of the support portion 30. The first engagement flange 75 of the first cover member 81 engages with the first slide groove 63 located in the first slide mounting region AR21. Also, the second engagement flange 76 of the first cover member 81 engages with the second slide groove 64 located in the first slide mounting region AR21.

[0089] In this embodiment, the second cover member 82 is disposed to the right of the first cover member 81 and is disposed so as to be spaced apart from the first cover member 81. The second cover member 82 is disposed so as to be in contact with the second front restricting portion 67 and the second rear restricting portion 68, and movement toward the second front restricting portion 67 and the second rear restricting portion 68 is restricted. The second cover member 82 is disposed in the second slide mounting region AR22 of the support portion 30. Here, the first engagement flange 75 of the second cover member 82 engages with the first slide groove 63 located in the second slide mounting region AR22. Also, the second engagement flange 76 of the second cover member 82 engages with the second slide groove 64 located in the second slide mounting region AR22.

[0090] The third cover member 83 is provided in a gap between the first front restricting portion 65 and the second front restricting portion 67 (in other words, a gap between the first rear restricting portion 66 and the second rear restricting portion 68) when the first cover member 81 and the second cover member 82 are attached to the support portion 30. In this embodiment, a gap is formed between the first cover member 81 and the second cover member 82 in a state in which the first cover member 81 and the second cover member 82 are attached to the support portion 30. Therefore, the third cover member 83 is disposed between the first cover member 81 and the second cover member 82. Here, the third cover member 83 is disposed in the attachment region AR11 of the support portion 30. The first engagement flange 75 of the third cover member 83 engages with the first slide groove 63 located in the attachment region AR11. Also, the second engagement flange 76 of the third cover member 83 engages with the second slide groove 64 located in the attachment region AR11.

[0091] In this embodiment, the third cover member 83 is configured to be disposed between the first cover member 81 and the second cover member 82, thereby fixing the positions of the first cover member 81 and the second cover member 82 in the first direction D1. Here, when the third cover member 83 is disposed in the attachment region AR11, the third cover member 83 contacts the first cover member 81 and the second cover member 82. In detail, the left end of the third cover member 83 contacts the right end of the first cover member 81, and the right end of the third cover member 83 contacts the left end of the second cover member 82. In this embodiment, when the third cover member 83 is disposed in the attachment region AR11, the position of the third cover member 83 in the first direction D1 is fixed. Therefore, the movement of the first cover member 81 in the first direction D1 is restricted by the first front restricting portion 65, the first rear restricting portion 66, and the third cover member 83. Therefore, the position of the first cover member 81 in the first direction D1 is fixed. The movement of the second cover member 82 in the first direction D1 is restricted by the second front restricting portion 67, the second rear restricting portion 68, and the third cover member 83. Therefore, the position of the second cover member 82 in the first direction D1 is fixed.

[0092] In this embodiment, as shown in FIG. 11, the first engaging recess 85 is provided in the first engaging flange 75 in each of the first cover member 81, the second cover member 82, and the third cover member 83. The first engaging recess 85 is provided on the upper surface of the first engaging flange 75 and is recessed downward from the upper surface. Also, the second engaging recess 86 is provided in the second engaging flange 76 in each of the first cover member 81, the second cover member 82, and the third cover member 83. The second engaging recess 86 is provided on the upper surface of the second engaging flange 76 and is recessed downward from the upper surface. The number of the first engaging recess 85 and the number of the second engaging recess 86 for each of the cover members 81, 82, and 83 are not particularly limited. Here, the number of the first engaging recess 85 and the number of the second engaging recess 86 are both two in each of the cover members 81 to 83. The first engagement flange 75 of each of the cover members 81 to 83 has a first engagement recess 85 provided at each of the left and right ends, and the second engagement flange 76 has a second engagement recess 86 provided at each of the left and right ends.

[0093] FIG. 12 is a bottom view showing the support part 30. In this embodiment, as shown in FIG. 12, the first slide groove 63 is provided with a first protrusion 69a that fits into the first engagement recess 85 (see FIG. 11). The second slide groove 64 is provided with a second protrusion 69b that fits into the second engagement recess 86 (see FIG. 11). Here, the first protrusion 69a protrudes downward from the upper surface of the first slide groove 63. The second protrusion 69b protrudes downward from the upper surface of the second slide groove 64. The first protrusion 69a is provided in the first slide groove 63 in the first slide mounting region AR21 and the first slide groove 63 in the second slide mounting region AR22. The second protrusion 69b is provided in the second slide groove 64 in the first slide mounting region AR21 and the second slide groove 64 in the second slide mounting region AR22.

[0094] Here, in the first slide groove 63 in the first slide mounting region AR21, one first protrusion 69a is provided at a position corresponding to the left first engagement recess 85 of the first cover member 81. Also, in the second slide groove 64 in the first slide mounting region AR21, one second protrusion 69b is provided at a position corresponding to the left second engagement recess 86 of the first cover member 81. Here, when the first cover member 81 slides along the first slide groove 63 and the second slide groove 64, the first protrusion 69a of the first slide mounting region AR21 fits into the left first engagement recess 85, and the second protrusion 69b of the first slide mounting region AR21 fits into the left second engagement recess 86, so that the first cover member 81 is less likely to move in the first direction D1 in a state where it is arranged in the first slide mounting region AR21. When the first cover member 81 is positioned in the first slide mounting area AR21, the right first engagement recess 85 does not fit into the first protrusion 69a, and the right second engagement recess 86 does not fit into the second protrusion 69b.

[0095] In this embodiment, in the second slide mounting region AR22, one first protrusion 69a is provided at a position corresponding to the right first engagement recess 85 of the second cover member 82, and one second protrusion 69b is provided at a position corresponding to the right second engagement recess 86 of the second cover member 82. When the second cover member 82 slides along the first slide groove 63 and the second slide groove 64, the first protrusion 69a of the second slide mounting region AR22 fits into the right first engagement recess 85, and the second protrusion 69b of the second slide mounting region AR22 fits into the right second engagement recess 86, so that the second cover member 82 is less likely to move in the first direction D1 when placed in the second slide mounting region AR22. Note that when the second cover member 82 is placed in the second slide mounting region AR22, the left first engagement recess 85 does not fit into the first protrusion 69a, and the left second engagement recess 86 does not fit into the second protrusion 69b.

[0096] In this embodiment, the first protrusion 69a is not provided in the first slide groove 63 in the mounting area AR11, and the second protrusion 69b is not provided in the second slide groove 64 in the mounting area AR11. Therefore, when the third cover member 83 is arranged in the mounting area AR11, the first protrusion 69a and the second protrusion 69b are not fitted into the first engagement recess 85 and the second engagement recess 86 of the third cover member 83. Here, since the third cover member 83 is arranged between the first cover member 81 and the second cover member 82, the movement in the first direction D1 is restricted by contacting the first cover member 81 and the second cover member 82. Therefore, even if the first protrusion 69a and the second protrusion 69b are omitted in the mounting area AR11, it is possible to make it difficult for the third cover member 83 to move in the first direction D1.

[0097] Fig. 13 is a left side view showing a state in which the first cover member 81, the second cover member 82, and the third cover member 83 are attached to the connected elongated member 20. In this embodiment, as shown in Fig. 13, the cover part 70 has an attachment part 90 that is attached to the connected elongated member 20 when the cover part 70 is removed from the support part 30. Here, the attachment part 90 is provided on the inner circumferential surface of the support body 31 of the support part 30. The configuration of the attachment part 90 is not particularly limited.

[0098] The mounting portion 90 has a first mounting flange 91 and a second mounting flange 92. In this embodiment, the first mounting flange 91 and the second mounting flange 92 are an example of a pair of mounting flanges of the present invention. The first mounting flange 91 and the second mounting flange 92 are provided on the inner peripheral surface of the cover body 71 and extend downward from the inner peripheral surface. The first mounting flange 91 and the second mounting flange 92 extend along the circumferential direction of the connecting long member 20. As shown in FIG. 10, the first mounting flange 91 and the second mounting flange 92 are rod-shaped. The first mounting flange 91 and the second mounting flange 92 are spaced apart from each other and arranged side by side in the second direction D1. The first mounting flange 91 is provided at the front of the cover body 71. The second mounting flange 92 is provided at the rear of the cover body 71.

[0099] As shown in FIG. 7, in a state where the mounting member 100 is mounted on the connected long member 20, the connected long member 20 is disposed in the cover body 71 of the cover part 70. At this time, the first mounting flange 91 is disposed on the front side of the connected long member 20, and the second mounting flange 92 is disposed on the rear side of the connected long member 20. In a state where the connected long member 20 is disposed in the cover body 71, the connected long member 20 is sandwiched between the first mounting flange 91 and the second mounting flange 92. In this state, as shown in FIG. 13, even if the cover part 70 is detached from the support part 30, the connected long member 20 is sandwiched between the first mounting flange 91 and the second mounting flange 92, so that the cover part 70 is attached to the connected long member 20. This makes it possible to prevent the cover part 70 from falling off the connected long member 20.

[0100] In this embodiment, the attachment portion 90 is provided for each of the multiple members constituting the cover portion 70. Here, as shown in FIG. 10, the attachment portion 90 (specifically, a first attachment flange 91 and a second attachment flange 92) is provided for each of the first cover member 81, the second cover member 82, and the third cover member 83. The first attachment flange 91 and the second attachment flange 92 are provided to extend downward at the center portion of the inner circumferential surface of the cover body 71 in the first direction D1 for each of the first cover member 81, the second cover member 82, and the third cover member 83. This allows each of the first cover member 81, the second cover member 82, and the third cover member 83 to be attached to the connecting elongated member 20 even when removed from the support portion 30. This makes it possible to make it difficult for the first cover member 81, the second cover member 82, and the third cover member 83 to fall off.

[0101] The above has described the configuration of the mounting member set 1 for the basket 10 according to this embodiment. Next, we will explain the procedure for using the mounting member set 1. First, we will explain the procedure for mounting the basket 10 to the connecting long member 20 using the mounting members 100.

[0102] First, as shown in FIG. 4, the cage 10 is attached to the support part 30 of the mounting member 100 and supported. Here, the first insertion part 41 and the second insertion part 42 are moved downward around the central part of the support body 31 of the support part 30, so that the support part 30 is bent into a U-shape. In this state, as shown in FIG. 3, the first insertion part 41 is inserted into the first insertion hole 11 of the cage 10, and the second insertion part 42 is inserted into the second insertion hole 12 of the cage 10. After that, when the bending of the support part 30 is released, the first cage rod-shaped part 13 of the cage 10 fits into the first recess 45 of the first insertion part 41 (see FIG. 6), and the second cage rod-shaped part 14 of the cage 10 fits into the second recess 46 of the second insertion part 42 (see FIG. 6). This makes it difficult for the support part 30 to move in the first direction D1 relative to the cage 10. In this manner, the cage 10 can be supported by the support portion 30.

[0103] As shown in Fig. 4, when the basket 10 is supported by the support part 30, the support legs 50 extending downward from the support body 31 come into contact with the mesh-like portion on the upper surface of the basket 10. This allows the support part 30 to stably support the basket 10.

[0104] Next, the cover part 70 is attached to the support part 30 supporting the basket 10, and the mounting member 100 is attached to the connected long member 20. At this time, as shown in FIG. 4, the connected long member 20 is first placed on the support body 31 of the support part 30. Here, as shown in FIG. 7, the connected long member 20 is placed on the mounting concave surface 56 of the mounting part 55 of the support body 31. Thereafter, the cover part 70 is attached to the support part 30 from above the connected long member 20. Here, the cover part 70 is attached to the support part 30 so that the cover part 70 and the support part 30 surround the connected long member 20 in the circumferential direction.

[0105] In this embodiment, when the cover part 70 is attached to the support part 30, the first cover member 81, the second cover member 82, and the third cover member 83 are attached to the support part 30 in this order. Here, the first cover member 81, the second cover member 82, and the third cover member 83 are attached to the support part 30 in this order in an attachment region AR11 (see FIG. 6) of the support part 30, and are slid relative to the support part 30 as necessary.

[0106] Here, first, the first cover member 81 is attached to the support portion 30 in the attachment region AR11. At this time, the first cover member 81 is attached to the support portion 30 from above the connected elongated member 20 so as to surround the connected elongated member 20 together with the support portion 30. Here, the first cover member 81 is deflected so as to bring the first engaging flange 75 and the second engaging flange 76 closer to each other. With the first cover member 81 in a deflected state, the first engaging flange 75 is inserted into the first slide groove 63, while the second engaging flange 76 is inserted into the second slide groove 64. As a result, in the first cover member 81, the first engaging flange 75 and the second engaging flange 76 are engaged with the first slide groove 63 and the second slide groove 64, respectively, and the connected elongated member 20 is disposed in the cover main body 71. At this time, the connected elongated member 20 is sandwiched between the first mounting flange 91 and the second mounting flange 92 of the first cover member 81, and the first cover member 81 is attached to the connected elongated member 20.

[0107] In this manner, after the first cover member 81 is attached to the support portion 30 in the attachment region AR11, the first cover member 81 is slid toward the first slide attachment region AR21. At this time, as shown in FIG. 6, the first cover member 81 is moved leftward along the first slide groove 63 and the second slide groove 64 until it comes into contact with the first front restricting portion 65 and the first rear restricting portion 66. When the first cover member 81 comes into contact with the first front restricting portion 65 and the first rear restricting portion 66, it is disposed in the first slide attachment region AR21. At this time, in the first cover member 81, the left first projection 69a (see FIG. 12) of the first slide groove 63 fits into the left first engagement recess 85 (see FIG. 11), and the left second projection 69b (see FIG. 12) of the second slide groove 64 fits into the left second engagement recess 86 (see FIG. 11).

[0108] In this manner, after the first cover member 81 is slid to the second slide mounting region AR21, the second cover member 82 is attached to the support portion 30 in the mounting region AR11. At this time, the second cover member 82 is attached to the support portion 30 from above the connected elongated member 20 so as to surround the connected elongated member 20 together with the support portion 30. Note that the procedure for attaching the second cover member 82 to the support portion 30 is the same as the procedure for attaching the first cover member 81 to the support portion 30, and therefore a detailed description thereof will be omitted here. After the second cover member 82 is attached to the support portion 30 in the mounting region AR11, the second cover member 82 is slid toward the second slide mounting region AR22. At this time, as shown in FIG. 6, the second cover member 82 is moved rightward along the first slide groove 63 and the second slide groove 64 until it comes into contact with the second front restricting portion 67 and the second rear restricting portion 68. When the second cover member 82 comes into contact with the second front restricting portion 67 and the second rear restricting portion 68, it is disposed in the second slide attachment area AR22. At this time, in the second cover member 82, the right first protrusion 69a (see FIG. 12) of the first slide groove 63 fits into the right first engagement recess 85 (see FIG. 11), and the right second protrusion 69b (see FIG. 12) of the second slide groove 64 fits into the right second engagement recess 86 (see FIG. 11).

[0109] In this way, by disposing the first cover member 81 and the second cover member 82 in the first slide attachment region AR21 and the second slide attachment region AR22, respectively, a gap is formed between the first cover member 81 and the second cover member 82. Next, the third cover member 83 is disposed between the first cover member 81 and the second cover member 82. Here, as shown in FIG. 6, the third cover member 83 is attached to the support portion 30 in the attachment region AR11. At this time, the third cover member 83 is attached to the support portion 30 from above the connected elongated member 20 so as to surround the connected elongated member 20 together with the support portion 30. Note that the procedure for attaching the third cover member 83 to the support portion 30 is the same as the procedure for attaching the first cover member 81 and the second cover member 82 to the support portion 30, and therefore a detailed description thereof will be omitted here. When the third cover member 83 is attached to the support portion 30 in the attachment region AR11, the third cover member 83 comes into contact with the first cover member 81 and the second cover member 82. This makes it difficult for the first cover member 81, the second cover member 82, and the third cover member 83 to move in the first direction D1.

[0110] In the above manner, by attaching the cover portion 70 to the support portion 30 supporting the cages 10, the attachment member 100 can be attached to the connected elongated member 20. As a result, the cages 10 supported by the support portion 30 can be attached to the connected elongated member 20. In this embodiment, as shown in FIG. 1, a plurality of attachment members 100 are attached to the connected elongated member 20 so as to be aligned in the first direction D1. Therefore, the plurality of cages 10 are attached to the connected elongated member 20 via the attachment members 100 so as to be aligned in the first direction D1. Here, oysters housed in the cages 10 are cultivated with the plurality of cages 10 attached to the connected elongated member 20.

[0111] When the oysters housed in the cages 10 are cultivated, the connected long members 20 are placed on the sea surface. Although not shown in the figures, a so-called float is attached to the top of the cages 10 attached to the connected long members 20. Therefore, the cages 10 are placed on the sea surface and are swayed by the force of the waves. As the cages 10 are swayed by this force of the waves, the shells of the multiple oysters housed in the cages 10 are scraped together. As the shells of the oysters are scraped in this way, the nutrients used for the growth of the shells are concentrated in the oyster meat, making it possible to grow delicious oysters.

[0112] In this embodiment, as shown by the arrow A1 in FIG. 2, the mounting member 100 can rotate in the circumferential direction relative to the connecting elongated member 20. Therefore, the cage 10 can rotate in the circumferential direction relative to the connecting elongated member 20. Here, the state in which the cage 10 is disposed below the connecting elongated member 20 is referred to as the first state, and the state in which the cage 10 is disposed above the connecting elongated member 20 is referred to as the second state. The cage 10 is configured to be rotatable in the circumferential direction of the connecting elongated member 20 so as to be switchable between the first state and the second state. When cultivating oysters housed in the cage 10, the cage 10 is periodically switched between the first state and the second state using a dedicated machine (not shown). In this way, by rotating the cage 10 and switching it from the first state to the second state or from the second state to the first state, high tide and low tide can be simulated. By periodically rotating the cage 10 between the first state and the second state, the shells of the multiple oysters housed in the cage 10 collide with each other more, resulting in more shaving. As a result, more nutrients can be concentrated in the oyster meat, allowing oysters that taste better to grow.

[0113] Incidentally, in order to rotate the basket 10 in this manner, the mounting member 100 is rotated in the circumferential direction of the connected long member 20. This may cause defects such as damage to the mounting member 100. The mounting member 100 in which a defect has occurred is removed from the connected long member 20 and replaced with a new mounting member 100. In this embodiment, as shown in FIG. 1, even if a plurality of mounting members 100 and a plurality of baskets 10 are attached to the connected long member 20 in a line in the first direction D1, the mounting members 100 can be individually removed from the connected long member 20.

[0114] Next, a procedure for removing the mounting member 100 according to this embodiment from the connected elongated member 20 will be described. Here, the mounting member 100 can be removed from the connected elongated member 20 by removing the cover part 70 from the support part 30. For example, the third cover member 83, the second cover member 82, and the first cover member 81 are removed from the support part 30 in this order.

[0115] When the third cover member 83 is removed from the support portion 30, the cover body 71 of the third cover member 83 is bent so that the first engaging flange 75 engaged with the first slide groove 63 and the second engaging flange 76 engaged with the second slide groove 64 are brought closer to each other. In a state in which the third cover member 83 is bent, the first engaging flange 75 is removed from the first slide groove 63, while the second engaging flange 76 is removed from the second slide groove 64. This allows the third cover member 83 to be removed from the support portion 30. As shown in FIG. 13, when the third cover member 83 is removed from the support portion 30, the first mounting flange 91 and the second mounting flange 92 of the third cover member 83 sandwich the connecting elongated member 20, so that the third cover member 83 is attached to the connecting elongated member 20. Therefore, even when the third cover member 83 is removed from the support portion 30, it is difficult for the third cover member 83 to fall into the sea. Furthermore, the third cover member 83 can be removed from the connected long member 20 by pulling the third cover member 83 from the connected long member 20 so as to release the connected long member 20 from being clamped by the first mounting flange 91 and the second mounting flange 92.

[0116] In this way, after the third cover member 83 is removed from the support part 30, for example, the second cover member 82 is removed from the support part 30. At this time, the second cover member 82 arranged in the second slide mounting area AR22 is first slid along the first slide groove 63 and the second slide groove 64 to the mounting area AR11. Then, the second cover member 82 arranged in the mounting area AR11 is removed from the support part 30. Note that the procedure for removing the second cover member 82 from the support part 30 is the same as the procedure for removing the third cover member 83 from the support part 30, so the explanation here is omitted. Even in the case of the second cover member 82, when it is removed from the support part 30, the second cover member 82 is attached to the connecting elongated member 20, so that the second cover member 82 is less likely to fall into the sea. When removing the second cover member 82 from the connected long member 20, as with the third cover member 83, it is advisable to pull the second cover member 82 from the connected long member 20 so as to release the clamping of the connected long member 20 between the first mounting flange 91 and the second mounting flange 92 of the second cover member 82.

[0117] In this way, after the third cover member 83 and the second cover member 82 are removed from the support part 30, the first cover member 81 is removed from the support part 30. At this time, the first cover member 81 arranged in the first slide mounting area AR21 is slid along the first slide groove 63 and the second slide groove 64 to the mounting area AR11. Then, the first cover member 81 arranged in the mounting area AR11 is removed from the support part 30. The procedure for removing the first cover member 81 from the support part 30 here is the same as the procedure for removing the third cover member 83 and the like from the support part 30, so the explanation here is omitted. Even when the first cover member 81 is removed from the support part 30, the first cover member 81 is attached to the connecting elongated member 20, so that the first cover member 81 is unlikely to fall into the sea. When removing the first cover member 81 from the connected long member 20, as with the third cover member 83, etc., it is advisable to pull the first cover member 81 from the connected long member 20 so as to release the clamping of the connected long member 20 between the first mounting flange 91 and the second mounting flange 92 of the first cover member 81.

[0118] By removing the first cover member 81 to the third cover member 83 in this order from the support part 30, the cover part 70 can be removed from the support part 30. Thereafter, by removing the support part 30 from the connected elongated members 20 placed on the placement part 55 of the support part 30, the attachment members 100 can be removed from the connected elongated members 20. By this procedure, the attachment members 100 can be individually removed from the connected elongated members 20.

[0119] As described above, in this embodiment, as shown in FIG. 2, the attachment member set 1 for the basket 10 includes the basket 10, the attachment member 100, and the connecting elongated member 20. The attachment member 100 is for attaching the basket 10 to the long connecting elongated member 20. As shown in FIG. 4, the attachment member 100 includes a support portion 30 for supporting the basket 10, and a cover portion 70 that is detachably provided on the support portion 30 and arranged to surround the connecting elongated member 20 together with the support portion 30. With this, the basket 10 can be attached to the connecting elongated member 20 by attaching the cover portion 70 to the support portion 30 so as to surround the connecting elongated member 20 together with the support portion 30 in a state in which the basket 10 is supported. Meanwhile, when the basket 10 is attached to the connecting elongated member 20, the basket 10 can be removed from the connecting elongated member 20 by removing the cover portion 70 from the support portion 30. Therefore, by attaching or detaching the cover portion 70 to or from the support portion 30, the basket 10 can be easily attached or detached to or from the connecting elongated member 20.

[0120] In this embodiment, as shown in FIG. 3, the support part 30 includes a support body 31 extending in a first direction D1 and formed of a flexible member, a first insertion part 41 provided at one end (here, the left end) of the support body 31 in the first direction D1 and inserted into the cage 10, and a second insertion part 42 provided at the other end (here, the right end) of the support body 31 in the first direction D1 and inserted into the cage 10. Here, the first insertion part 41 is inserted into the cage 10 by being inserted into a first insertion hole 11 formed in the cage 10. The second insertion part 42 is inserted into the cage 10 by being inserted into a second insertion hole 12 formed in the cage 10. This makes it possible to easily support the cage 10 on the support part 30 by inserting the first insertion part 41 and the second insertion part 42 into the cage 10 while bending the support body 31.

[0121] 6, in this embodiment, the first insertion portion 41 and the second insertion portion 42 have tapered shapes 43, 44 in which the width (here, the length in the second direction D2) decreases toward the tip. In this manner, the first insertion portion 41 and the second insertion portion 42 can be easily inserted into the basket 10 by inserting them from the tapered shapes 43, 44 into the basket 10 (more specifically, the first insertion hole 11 and the second insertion hole 12).

[0122] In this embodiment, the first insertion portion 41 and the second insertion portion 42 each have a first recess 45 and a second recess 46 into which a part of the cage 10 fits when inserted into the cage 10. Here, when the support portion 30 is supporting the cage 10, the first recess 45 fits into the first basket rod-shaped portion 13 (see FIG. 3) of the cage 10, and the second recess 46 fits into the second basket rod-shaped portion 14 (see FIG. 3) of the cage 10. This makes it possible to make it difficult for the cage 10 to move relative to the support portion 30 when the support portion 30 is supporting the cage 10.

[0123] In this embodiment, as shown in Fig. 4, the support part 30 has a support leg 50 that extends from the support body 31 toward the cage 10 and contacts the cage 10. This allows the cage 10 to be supported by the first insertion part 41, the second insertion part 42, and the support leg 50, so that the support part 30 can stably support the cage 10.

[0124] 5, in this embodiment, the cover part 70 extends in the first direction D1 and is configured to restrict bending of the support body 31 of the support part 30 when attached to the support part 30. In this way, by attaching the cover part 70 to the support part 30, it is possible to make it difficult for the support body 31 of the support part 30 to bend. Therefore, it is possible to make it difficult for the basket 10 to be removed from the support part 30.

[0125] In this embodiment, as shown in FIG. 8, the support portion 30 has a first slide protrusion 61 provided at one end (here, the front end) of the support body 31 in the second direction D2 and extending in the first direction D1, and a second slide protrusion 62 provided at the other end (here, the rear end) of the support body 31 in the second direction D2 and extending in the first direction D1 so as to face the first slide protrusion 61. A first slide groove 63 extending in the first direction D1 is formed on the second slide protrusion 62 side of the first slide protrusion 61. A second slide groove 64 extending in the first direction D1 is formed on the first slide protrusion 61 side of the second slide protrusion 62. As shown in FIG. 7, the cover portion 70 has a cover body 71, a first engagement flange 75, and a second engagement flange 76. The cover body 71 extends in the first direction D1 and is recessed in a direction away from the support portion 30 so that the connecting elongated member 20 can enter. The cross-sectional shape of the cover body 71 when viewed from the first direction D1 is, for example, U-shaped. The first engagement flange 75 is provided at the end of the cover body 71 on the support portion 30 side and at one end (here, the front end) in the second direction D2, and engages with the first slide groove 63. The second engagement flange 76 is provided at the end of the cover body 71 on the support portion 30 side and at the other end (here, the rear end) in the second direction D2, and engages with the second slide groove 64. In this way, the first engagement flange 75 and the second engagement flange 76 of the cover part 70 are engaged with the first slide groove 63 and the second slide groove 64, respectively, so that the cover part 70 can regulate the deflection of the support part 30.

[0126] In this embodiment, as shown in Fig. 8, the support part 30 is provided so as to protrude from the support main body 31, extends in the first direction D1, and has a mounting part 55 on which the connected elongated member 20 (see Fig. 7) can be mounted. With this, by attaching the cover part 70 to the support part 30 with the connected elongated member 20 placed on the mounting part 55, it is possible to attach the cover part 70 to the support part 30 while determining the position of the connected elongated member 20.

[0127] In this embodiment, the connected long member 20 is a member having a cylindrical outer circumferential shape extending in the first direction D1. The mounting portion 55 has a mounting concave surface 56 that is recessed along the outer circumferential surface of the connected long member 20. With this, by mounting the connected long member 20 on the mounting concave surface 56 that has a shape that follows the outer circumferential shape of the connected long member 20, it is possible to easily position the connected long member 20 with respect to the support portion 30.

[0128] In this embodiment, as shown in FIG. 8, the support portion 30 has a first front restricting portion 65 provided at one end (here, the left end) of the first slide groove 63 in the first direction D1, a first rear restricting portion 66 provided at one end (here, the left end) of the second slide groove 64 in the first direction D1, a second front restricting portion 67 provided at the other end (here, the right end) of the first slide groove 63 in the first direction D1, and a second rear restricting portion 68 provided at the other end (here, the right end) of the second slide groove 64 in the first direction D1. As shown in FIG. 5, the cover portion 70 is composed of a plurality of members, and here has a first cover member 81, a second cover member 82, and a third cover member 83. The first cover member 81 and the second cover member 82 are slidable in the first slide groove 63 and the second slide groove 64. The third cover member 83 is provided in a gap (here, a gap between the first cover member 81 and the second cover member 82) between the first restricting portions 65, 66 and the second restricting portions 67, 68 when the first cover member 81 and the second cover member 82 are attached to the support portion 30, and fixes the positions of the first cover member 81 and the second cover member 82 in the first direction D1. Any one of the first cover member 81, the second cover member 82, and the third cover member 83 (here, the first cover member 81) comes into contact with the first restricting portions 65, 66, and is restricted from moving toward the first restricting portions 65, 66. Any other one of the first cover member 81, the second cover member 82, and the third cover member 83 (here, the second cover member 82) comes into contact with the second restricting portions 67, 68, and is restricted from moving toward the second restricting portions 67, 68. In this embodiment, after the first cover member 81 and the second cover member 82 are attached to the support portion 30, the third cover member 83 is inserted into the gap between the first regulating portions 65, 66 and the second regulating portions 67, 68, making it difficult for the cover portion 70 to move in the first direction D1 relative to the support portion 30.

[0129] In this embodiment, as shown in Fig. 9, the first cover member 81, the second cover member 82, and the third cover member 83 have the same shape and the same size. This allows the first cover member 81 to the third cover member 83 to be used with their positions interchanged. Also, in this embodiment, the end portions of the first cover member 81, the second cover member 82, and the third cover member 83 in the first direction D1 are each thicker toward the end. This allows the rigidity of the first cover member 81 to the third cover member 83 to be increased.

[0130] 13, in this embodiment, the cover part 70 has an attachment part 90 that is attached to the connected elongated member 20 when the cover part 70 is removed from the support part 30. This allows the cover part 70 to be attached to the connected elongated member 20 by the attachment part 90 when the cover part 70 is removed from the support part 30, making it difficult for the cover part 70 to fall off.

[0131] In this embodiment, the attachment portion 90 is provided on the inner circumferential surface of the cover body 71. This makes it possible to make the attachment portion 90 less likely to get caught on an external object or the like.

[0132] In this embodiment, the mounting portion 90 extends inward from the inner circumferential surface of the cover body 71 along the circumferential direction of the connected long member 20, and has a pair of mounting flanges 91, 92 aligned in the second direction D2 so as to sandwich the connected long member 20. In this manner, by sandwiching the connected long member 20 between the pair of mounting flanges 91, 92, the cover portion 70 can be attached to the connected long member 20.

[0133] 1, in this embodiment, a plurality of mounting members 100 are provided on the connected elongated member 20, lined up in the first direction D1. A plurality of baskets 10 are attached to the mounting members 100, lined up in the first direction D1. With this, by removing the cover portion 70 of the mounting member 100 from the support portion 30, the baskets 10 can be individually removed from the connected elongated member 20 while other baskets 10 are attached to the connected elongated member 20.

[0134] In this embodiment, oysters are housed in the cage 10, and the cage 10 is used when cultivating oysters. That is, the mounting member set 1 (here, the mounting member 100, the cage 10, and the connecting long member 20) is used in seawater when cultivating oysters.

[0135] However, the attachment member set 1 here is not limited to being used for oysters, and is not limited to being used for aquaculture. For example, the attachment member set 1 may be used when cultivating shellfish other than oysters, or may be used when cultivating aquatic organisms such as fish other than shellfish. That is, the cage 10 may be used to house shellfish other than oysters, or may be used to house aquatic organisms such as fish other than shellfish. In addition, in this embodiment, the attachment member set 1 is used in seawater, but it may be used in water including seawater. The attachment member set 1 may be used in freshwater such as a river. That is, the attachment member set 1 may be used for organisms living in freshwater, such as freshwater fish.

[0136] The attachment member set 1 may also be used for purposes other than aquaculture. For example, the attachment member set 1 may be used for purposes other than aquaculture, such as simply growing (raising) organisms, and the cage 10 may be attached to the connecting elongated member 20 via the attachment member 100 in a state in which the organisms to be bred are housed therein.

[0137] Furthermore, the attachment member set 1 is not limited to those used in cultivating or raising living organisms, and the cage 10 is not limited to those that house living organisms. The attachment member set 1 may be for collecting garbage, and for example, the cage 10 may be for collecting garbage floating in water. The cage 10 in which garbage can be housed may be attached to the connecting elongated member 20 via the attachment member 100.

[0138] Furthermore, the attachment member set 1 is not limited to being used underwater, and may be used on land, for example. For example, the attachment member set 1 may be used for drying things in the sun. In order to dry things contained in the basket 10 in the sun, the basket 10 may be attached to the connecting elongated member 20 via the attachment member 100.

[0139] In this embodiment, the cover section 70 of the mounting member 100 is composed of three members, namely, the first cover member 81, the second cover member 82, and the third cover member 83. However, the cover section 70 may be composed of one member, or may be composed of two or four or more members. When the cover section 70 is composed of a plurality of members, some of the members may be members for sliding, the position of which is determined by engaging with the first slide groove 63 and the second slide groove 64 and sliding. In addition, some of the other members of the plurality of members may be members for fixing the position of the members for sliding, which are disposed in the gaps between the members for sliding.
