Summary of the Invention

Problems to be Solved by the Invention

[0004] However, depending on the variety of medaka and the type of ornamental fish, the water depth where it is easy to lay eggs on the spawning bed varies, and it has been necessary to change the type of spawning bed. Therefore, a spawning bed whose installation position can be adjusted has been desired.

[0005] An object of the present disclosure is to provide a spawning bed whose installation position can be adjusted. [Means for solving the problem]

[0006] The spawning bed of the present disclosure comprises a porous portion for which ornamental fish eggs are attached, a base to which the porous portion is attached, and a detachable portion attached to the porous portion and / or the base, which is detachable from the wall of the aquarium. [Brief explanation of the drawing]

[0007] [Figure 1] Figure 1 is a perspective view showing a spawning bed according to one embodiment installed in a tank. [Figure 2] Figure 2 is a perspective view showing the spawning bed according to the same embodiment installed in a tank. [Figure 3] Figure 3 is a perspective view showing the spawning bed according to the same embodiment installed in a tank. [Figure 4] Figure 4 is an exploded perspective view of the spawning bed according to the same embodiment. [Figure 5] Figure 5 is a side view of the spawning bed according to the same embodiment. [Figure 6] Figure 6 is a longitudinal cross-sectional view of the spawning bed according to the same embodiment. [Modes for carrying out the invention]

[0008] The following description of a spawning bed according to one embodiment will be made with reference to Figures 1 to 6. Note that the dimensional ratios in the drawings do not necessarily match the actual dimensional ratios, nor do the dimensional ratios between the drawings necessarily match. Figures 1 to 3 are perspective views showing the spawning bed 1 according to one embodiment attached to a tank 100.

[0009] As shown in Figure 1, the spawning bed 1 is detachable from the wall surface 100a of the aquarium 100 and is used in a state where at least a portion of it is submerged in water within the aquarium 100. By using the spawning bed 1, the spawning rate of ornamental fish in the aquarium 100 can be increased. Examples of ornamental fish include medaka, goldfish, and tropical fish.

[0010] The tank 100 comprises, for example, a front wall 101, a pair of side walls 102, 102, a rear wall 103, a bottom wall 104, and a lid wall (not shown). The tank 100 is formed in a rectangular or square shape in plan view, for example. However, the tank 100 may be formed in a circular or polygonal shape (triangle, pentagon, hexagon) in plan view.

[0011] Each wall 101-104 (including the lid wall) is made of, for example, glass or transparent resin, and the spawning bed 1 is detachable from the wall surface 100a of each wall 101-104 (including the lid wall). Figure 1 shows an example in which the spawning bed 1 is attached to the wall surface 100a of the rear wall 103, but is not limited to this. The spawning bed 1 is detachable from any one of the wall surfaces 100a of the front wall 101, side wall 102, rear wall 103, bottom wall 104, and lid wall.

[0012] As shown in Figures 1 to 3, the spawning bed 1 is configured to allow adjustment of its installation position and orientation within the aquarium 100. For example, by installing the spawning bed 1 horizontally in the aquarium 100 as shown in Figure 3, it becomes easier for medaka and other fish with long fins to lay their eggs on the spawning bed 1. Alternatively, the spawning bed 1 may be configured to allow adjustment only of its installation position within the aquarium 100.

[0013] Figure 4 is an exploded perspective view of the spawning bed 1, Figure 5 is a side view (or plan view depending on the installation orientation) of the spawning bed 1, and Figure 6 is a longitudinal section (or cross section depending on the installation orientation) of the spawning bed 1. As shown in Figures 4 to 6, the spawning bed 1 comprises a porous section 2 for ornamental fish eggs to attach to, a fixing section 3 to which the porous section 2 is fixed, and a detachable section 4 that is attached to the porous section 2 and / or the fixing section 3 and is detachable from the wall surface 100a of the aquarium 100. With this configuration, the installation position and orientation of the spawning bed 1 can be adjusted according to the type and characteristics of the ornamental fish. This eliminates the need to change the type of spawning bed depending on the type of ornamental fish, thereby reducing the financial burden on the aquarist. Furthermore, by adjusting the installation position and orientation of the spawning bed 1, the spawning rate of ornamental fish can be increased.

[0014] The porous section 2 is formed from a porous (structural) material such as nonwoven fabric, wool, sponge, mesh, or palm fiber. The porous section 2 is composed of, for example, a plurality of rod-shaped bodies 21, one end of which is fixed to a fixing hole 31 (see Figure 6) of the fixing section 3. The porous section 2 is formed, for example, in the shape of a frustoconical pyramid, with the rod-shaped bodies 21 radiating outwards from the fixing section 3. The rod-shaped bodies 21 may have a constant thickness and width, or their thickness and width may decrease (or increase) towards the tip.

[0015] The porous section 2 is formed, for example, by making multiple cuts at predetermined intervals from one side of a rectangular nonwoven fabric toward the opposite side, connecting multiple rod-shaped bodies 21 by leaving a portion of the opposite side uncut, and then folding (or rolling) the uncut portion. However, the porous section 2 is not limited to the above, and may be composed of multiple loop-shaped bodies made by looping rod-shaped members, or it may be formed by rolling a mesh body into a roughly spherical shape.

[0016] The fixing part 3 (also called the float part 3) is preferably made of a material with a density lower than water. With this configuration, when the spawning bed 1 is removed from the wall surface 100a of the aquarium 100, the spawning bed 1 can float. This makes it easier to retrieve the spawning bed 1 as the caretaker's hands do not need to be placed in the water. The fixing part 3 is formed in the shape of a disc or cylinder, for example, from foamed resin (it can be made of the same material as the porous part 2). A fixing hole 31 (see Figure 6) for fixing the porous part 2 is provided in the center of the fixing part 3.

[0017] The detachable part 4 is attached to the porous part 2 and / or the fixed part 3. In this embodiment, the detachable part 4 is attached to the porous part 2, but is not limited to that. The detachable part 4 may be attached to the fixed part 3, or to both the porous part 2 and the fixed part 3.

[0018] The detachable part 4 preferably includes a detachable member 41 that can be attached to and detached from the wall surface 100a of the water tank 100, and an arm member 42 that connects at least a part of the detachable member 41 to the porous part 2 and / or the fixing part 3. According to such a configuration, the porous part 2 can be separated from the wall surface 100a of the water tank 100, and the number of eggs that can be laid on the porous part 2 can be increased. Thereby, the spawning rate of ornamental fish can be increased.

[0019] As shown in FIGS. 5 and 6, the arm member 42 is preferably inclined in the direction from the porous part 2 toward the fixing part 3 in a direction away from the detachable member 41 with respect to a plane orthogonal to the contact surface 41a of the detachable part 4 that contacts the wall surface 100a of the water tank 100 (in FIGS. 5 and 6, it is inclined downward in the leftward direction). According to such a configuration, the porous part 2 can be tilted in a direction away from the wall surface 100a of the water tank 100, and the number of eggs that can be laid on the porous part 2 can be increased. Thereby, the spawning rate of ornamental fish can be increased.

[0020] The detachable member 41 has a contact surface 41a that contacts the wall surface 100a of the water tank 100. The inclination angle θ of the arm member 42 with respect to a plane orthogonal to the contact surface 41a is preferably 0.5 degrees or more. Thereby, the porous part 2 can be separated from the wall surface 100a of the water tank 100. The inclination angle θ is preferably 20 degrees or less. Thereby, an increase in the length of the arm member 42 for securing a gap between the fixing part 3 and the detachable member 41 can be suppressed. The inclination angle θ is more preferably 10 degrees or less. In the present embodiment, the inclination angle θ is 5 degrees, but it is not limited thereto. For example, the inclination angle θ may be 0 degrees, that is, the arm member 42 may extend in a direction orthogonal to the contact surface 41a of the detachable part 4 that contacts the wall surface 100a of the water tank 100. Also, the arm member 42 may be inclined in the direction from the fixing part 3 toward the porous part 2 in a direction away from the detachable member 41 with respect to a plane orthogonal to the contact surface 41a.

[0021] The detachable part 4 is preferably configured to be detachably attached to the porous part 2 and / or the fixing part 3. According to such a configuration, by removing the detachable part 4 from the porous part 2 and / or the fixing part 3, for example, the spawning bed 1 can be floated (or sunk to the bottom of) in the water tank 100. Also, by removing the detachable part 4 from the porous part 2 and / or the fixing part 3, the cleaning of the spawning bed 1 can be facilitated. [[ID=I]]

[0022] In the present embodiment, as shown in FIG. 4, the arm member 42 includes a C-shaped clip portion 421 for attaching to and detaching from the porous part 2. Thereby, the arm member 42 can be attached to and detached from the base portion of the porous part 2. The base portion of the porous part 2 is formed in a columnar shape (such as a substantially cylindrical shape or a substantially prismatic shape) for example, to enable the attachment and detachment of the clip portion 421. Note that the arm member 42 is not limited to the above, and may be detachably attached to the fixing part 3, or may be detachably attached to both the porous part 2 and the fixing part 3. Also, the arm member 42 may be fixed to the porous part 2 and / or the fixing part 3.

[0023] The arm member 42 is preferably configured to be detachably attached to the detachable member 41. Thereby, by removing the arm member 42 from the detachable member 41, the cleaning of the spawning bed 1 can be facilitated. The detachable member 41 is composed of a first detachable member 411 and a second detachable member 412, and the arm member 42 is configured to be detachably attached to the first detachable member 411.

[0024] In the present embodiment, the arm member 42 includes a snap fit portion 422 for attaching to and detaching from the first detachable member 411, and the first detachable member 411 includes a detachable hole 411d for attaching to and detaching the snap fit portion 422. The detachable hole 411d is shaped to be engageable with the claw of the snap fit portion 422. Note that the arm member 42 is not limited to the above, and may be fixed to the first detachable member 411.

[0025] In this embodiment, the arm member 42 is provided with a positioning projection 423 as shown in Figure 6, and the first attachment / detachment member 411 is provided with a groove 411e into which the positioning projection 423 fits, but is not limited to this. The positioning projection 423 extends in the width direction of the arm member 42.

[0026] Preferably, the first detachable member 411 and the second detachable member 412 are equipped with magnets 411a and 412a, respectively. With this configuration, the spawning bed 1 can be attached to and detached from the wall surface 100a of the aquarium 100 by attaching and detaching the magnets 411a and 412a, making it easy to attach and detach the spawning bed 1. In addition, for example, by moving the magnet 412a provided on the outside of the aquarium 100, the mounting position and orientation of the spawning bed 1 can be adjusted from the outside of the aquarium 100.

[0027] The first detachable member 411 is installed inside the water tank 100, and the second detachable member 412 is installed outside the water tank 100. The first detachable member 411 is provided with a first magnet 411a, and the second detachable member 412 is provided with a second magnet 412a. The magnets 411a and 412a are, for example, round neodymium magnets. The thickness of the wall surface 100a of the water tank 100 is preferably 6 mm or less. This ensures sufficient attraction force between the magnets 411a and 412a and the wall surface 100a of the water tank 100.

[0028] The first detachable member 411 comprises a first case 411b for housing the first magnet 411a, and a first lid 411c that covers the first magnet 411a housed in the first case 411b. The first case 411b is formed in the shape of a rounded rectangle with one end rounded, and the first magnet 411a is housed on one end. The other end of the first case 411b is provided with a detachable hole 411d and a groove 411e.

[0029] The second detachable member 412 comprises a second case 412b for housing the second magnet 412a, and a second lid 412c that covers the second magnet 412a housed in the second case 412b. The second case 412b is formed in a circular shape, and a circular projection 412d that protrudes radially outward is provided on the periphery of the end of the second case 412b opposite to the second lid 412c. This makes it easier to grasp the second detachable member 412 and improves its operability.

[0030] (modified version) In the above embodiment, the detachable member 41 is composed of a first detachable member 411 and a second detachable member 412, and magnets 411a and 412a are provided on each of the detachable members 411 and 412, but it is not limited to this. For example, the detachable member 41 may be a suction cup (suction rubber) or the like.

[0031] In the above embodiment, the attachment / detachment part 4 includes an arm member 42, but is not limited to this. For example, the attachment / detachment part 4 may not include an arm member 42 and may consist only of an attachment / detachment member 41. In this example, the attachment / detachment member 41 is fixed to the porous part 2 and / or the fixing part 3.

[0032] [1] As described above, the spawning bed 1 according to this embodiment comprises a porous part 2 for which ornamental fish eggs are attached, a fixing part 3 to which the porous part 2 is fixed, and a detachable part 4 that is attached to the porous part 2 and / or the fixing part 3 and is detachable from the wall surface 100a of the aquarium 100.

[0033] With this configuration, the installation position of the spawning bed 1 can be adjusted according to the type and characteristics of the ornamental fish.

[0034] [2] Furthermore, in the spawning bed 1 described in [1] above, it is preferable that the fixing part 3 is made of a material with a density lower than water.

[0035] With this configuration, when the spawning bed 1 is removed from the wall surface 100a of the tank 100, the spawning bed 1 can float. This makes it easier to retrieve the spawning bed 1.

[0036] [3] Furthermore, in the spawning bed 1 described in [1] or [2] above, it is preferable that the detachable part 4 comprises a detachable member 41 that can be attached to and detached from the wall surface 100a of the aquarium 100, and an arm member 42 that connects at least a part of the detachable member 41 to the porous part 2 and / or the fixed part 3.

[0037] With this configuration, the porous section 2 is separated from the wall surface 100a of the aquarium 100, increasing the number of eggs that can be laid in the porous section 2. This makes it possible to increase the spawning rate of ornamental fish.

[0038] [4] Furthermore, in the spawning bed 1 described in [3] above, it is preferable that the arm member 42 is inclined in a direction toward the fixed part 3 from the porous part 2 toward the fixed part 3 toward the direction toward away from the detachable member 41, with respect to a plane perpendicular to the contact surface 41a of the detachable part 4 that contacts the wall surface 100a of the aquarium 100.

[0039] With this configuration, the porous section 2 is tilted away from the wall surface 100a of the aquarium 100, increasing the number of eggs that can be laid in the porous section 2. This can increase the spawning rate of ornamental fish.

[0040] [5] Furthermore, in the spawning bed 1 described in any one of [1] to [4] above, it is preferable that the attachment / detachment part 4 is configured to be detachably attached to the porous part 2 and / or the fixed part 3.

[0041] With this configuration, by removing the detachable part 4 from the porous part 2 and / or the fixed part 3, the spawning bed 1 can be installed, for example, floating in the aquarium 100 (submerged at the bottom of the aquarium 100).

[0042] [6] Furthermore, in the spawning bed 1 described in any one of [1] to [5] above, it is preferable that the detachable part 4 includes a detachable member 41 that can be attached to the wall surface 100a of the aquarium 100, and the detachable member 41 is composed of a first detachable member 411 and a second detachable member 412, and the first detachable member 411 and the second detachable member 412 are each equipped with magnets 411a and 412a.

[0043] With this configuration, the spawning bed 1 can be easily attached to and detached from the wall surface 100a of the aquarium 100 by attaching and detaching the magnets 411a and 412a. Furthermore, for example, by moving the magnet 412a installed on the outside of the aquarium 100, the mounting position and orientation of the spawning bed 1 can be adjusted from the outside of the aquarium 100.

[0044] It should be noted that the spawning bed is not limited to the configuration of the embodiment described above, nor is it limited to the effects and benefits described above.
