Description

  The present invention relates to a catching device for aquatic organisms such as ornamental fish, which are widely cultivated in an aquarium.

  Conventionally, so-called “tamo” nets have been used to capture aquatic organisms bred in an aquarium (see Patent Documents 1 to 3). Although the size varies depending on the size of the aquarium and the size of the aquatic organism to be captured, basically a specific aquatic organism in the aquarium is selected using a tamo net with a net attached to the tip of the rod. Scoop up and capture.

However, especially in the case of small aquatic organisms (aquarium fish, appreciation shrimp, etc.) bred for ornamental use, they may jump out of the net by jumping out of the net. This is because when the water is scooped up with a tamo-net, all the water in the net leaks out of the net, and the aquatic creatures jump off the ground and dislike it. In order to prevent this, for example, it can be dealt with by increasing the depth of the net, but if the net is deepened, it is difficult to operate in the aquarium (the deep net flutters when manipulating in the aquarium) ). Further, when the net is deepened, the aquatic organisms are exposed, and the nets are easily entangled with the aquatic organisms. The entanglement of the nets may damage the aquatic organisms. In the case of ornamental aquatic organisms, damage to the body means a reduction in commercial value.
Furthermore, in the case of a tammo net, when the water is captured and scooped up, naturally all of the water flows out of the turtle net, so the aquatic body may come into contact with the air, possibly causing skin diseases and the like.
In addition, in the case of a fine-tucked net, clogging may occur due to dirt in the water tank if used continuously.
In addition, in the case of crustaceans such as crabs and shrimps, the net is grabbed by hand or foot, so it takes time to remove it from the net, and sometimes the limb is shredded.

  The present invention has been made to solve the above problems.

  In order to solve the above-mentioned problems, the present invention is a capture tool for capturing aquatic organisms grown in an aquarium, and has a fixed shape for capturing the aquatic organisms, and has a depth smaller than the opening width (shallow). And a rod-like operation unit connected to the capture unit, a drain hole is formed at a position higher than a certain height of the capture unit, and water is supplied in a region up to the drain hole formation height. A catching device in an aquarium characterized by being capable of being held.

  In other words, the trapping part is not constituted by a net, but is a fixed trapping part having a fixed shape, and the depth of the trapping part is made smaller (shallow) than the width of the opening serving as an entrance / exit for aquatic organisms. Facilitates handling in the water tank. In addition, even in the case of a shallow bottom, a certain amount of water remains without leaking at the bottom during capture, so that the captured aquatic organisms are not so violent. That is, the aquatic organism is prevented from jumping out of the catching tool, and the aquatic organism is prevented from being damaged. Even when captured, the aquatic body never leaves the water. In addition, even if it is desired to place the catching device once during the operation, if the catching device according to the present invention is used, the catching portion is floated on the water surface while the tip of the rod-like operation portion is placed on the edge of the water tank. be able to. In short, it is not necessary to leave the tank outside, so that wetting around the tank can be prevented.

  Moreover, you may form the said capture | acquisition part with the one triangular panel which forms a bottom face, and the six triangular panels which comprise a wall surface. With such a configuration, for example, the capture unit can be formed by folding a single continuous triangular panel. That is, it is excellent in design property and can use a die-cut panel, so that low cost can be realized.

  Moreover, you may comprise all the areas of the triangular panel which forms the said wall surface larger than the area of the triangular panel which forms the said bottom face. If comprised in this way, when a panel is assembled, since it becomes a shape which spreads from a bottom face to an opening part, it is easy to capture aquatic organisms in an aquarium.

  The opening of the capture part is formed in a triangular shape in plan view and has an edge of three sides, and the edge of one or two sides of the edge of the three sides is inside the capture part. You may comprise so that a return member may be provided facing. If comprised in this way, even if the scooped aquatic organism jumps etc., the jumping out from an opening part can be prevented effectively.

  Further, a guide member may be provided on the inner peripheral surface of the edge that is not provided with the return member. If comprised in this way, when aquatic organisms are accommodated in the capture part in the aquarium, it is possible to prevent the aquatic organisms from being sandwiched at the edges.

  Moreover, you may comprise the said operation part below the height position of the edge part of the said opening part, and attaching with an angle toward the said bottom face side. If comprised in this way, when performing operation which attaches the opening part of a capture part to the inner peripheral wall surface of a water tank, for example, presence of an operation part does not become obstructive easily.

  Moreover, you may comprise at least the said capture part with a transparent material. If comprised in this way, while the design property improves, the capture condition can be confirmed from any direction. It is also possible to observe carefully in a state where the aquatic organisms have been isolated by capture.

  Moreover, you may comprise the said capture tool with an acrylic material. Especially in aquariums that handle ornamental fish, lighting for ornamental fish (often contains ultraviolet rays for growing aquatic plants) is often used to improve the appearance, but acrylic materials are illumination lamps. It is durable and suitable for light irradiation. In addition, there are many cases where there are restrictions on the space to put the trapping device in the water tank, such as when the water tank is stacked up and down, for example, if the operation part is made of acrylic material, a considerable degree of bending Therefore, even in a narrow space, the operation portion can be bent and placed in the water tank, which is convenient.

  Further, a floating body may be provided at one end of the operation unit. By providing this floating body, even if the trap is dropped into the water tank, the entire trap does not sink to the bottom of the water tank. That is, even when the body falls down, at least the floating body has a face on the surface of the water, so that the catcher can be picked up without getting the hands wet. In addition, it is not necessary to put your hand close to the soil laid in the aquarium, so the soil in the aquarium will not be unwound due to disturbance of the water flow when you put your hand in, and the water in the aquarium will not be inadvertently clouded .

  “Aquatic organisms” as used in this specification and claims are not limited to fish, but also shellfish such as crabs and shrimps, as well as turtles, newts, frogs, salamanders, Mexican salamanders (also known as pearls). It is a concept that widely includes aquatic organisms that are nurtured with a certain amount of water. In particular, it means small creatures raised in the aquarium for viewing purposes.

  According to the present invention, even when scooped up, the aquatic organism can be maintained in the water, so that the disease and damage of the aquatic organism can be prevented, and handling in the water tank is also facilitated. There is no clogging.

<Structure of the trap>
A catching tool 100 as an example of an embodiment of the present invention is a catching tool used to select only a specific individual from shrimp for appreciation and appreciation fish bred and raised in an aquarium. It is comprised from the substantially triangular capture part 110 and the operation part (handle bar 142, the floating body 144) connected to the said capture part 110 via the joint 140 (refer FIG. 1).

  The handle bar 142 is attached to the capturing unit 110 with a slight inclination (to the bottom surface side). That is, it attaches so that angle (theta) 1 may be formed with respect to the upper edge part of the capture part 110 (refer FIG. 2).

  The capturing unit 110 includes a capturing unit main body configured by seven triangular panels (first panel 111 to seventh panel 117), return members 118 and 119, and a guide member 120 (FIG. 4). reference). Moreover, it has the opening part 110a of the substantially triangular shape in planar view.

  The capture part main body is joined at an obtuse angle (an angle formed on the inner peripheral surface side of the capture part 110 is an obtuse angle) between the three sides of the triangular fourth panel 114 constituting the bottom surface. Three triangular panels (second panel 112, third panel 113, seventh panel 117) and another three triangular panels (first panel) joined to fill the gap between these three panels. 1 panel 111, 5th panel 115, and 6th panel 116). Among these, one side of each of the first panel 111, the fifth panel 115, and the sixth panel 116 serves as an edge that forms the opening 110 a of the capture unit 110. That is, the fourth panel 114 is a bottom surface, and the other six panels are surrounded by the fourth panel 114 (first panel 111, second panel 112, third panel 113, fifth panel 115, sixth panel 116, seventh panel 117). Are assembled so that their vertices are staggered in the vertical direction to form a wall surface, and constitute the trap body.

  The fourth panel 114 constituting the bottom surface is configured to have the smallest area compared to other panels. As a result, the shape expands from the bottom surface to the opening 110a. Further, the maximum width W of the opening 110a is configured to be larger than the depth D. The first panel 111 located on the front side has three drain holes 111a arranged side by side at a height of about 2/3 from the bottom surface. In this embodiment, the diameter of the drain hole 111a is 3 mm. Further, the drain hole 111a is formed so as to penetrate the inside and outside of the capturing part 110.

  Seventh vertical slits 115a having a width of about 1 mm are formed in parallel on the fifth panel 115 forming a part of the right side surface of the capture unit 110. All of the slits 115 a are formed so as to penetrate the inside and outside of the capturing part 110. Similarly, seven vertical slits 116 a having a width of about 1 mm are formed in parallel on the sixth panel 116 that forms a part of the left side surface of the capture unit 110. All the slits 116 a are also formed so as to penetrate the inside and outside of the capturing part 110.

  As described above, the capturing unit 110 has a substantially triangular shape in plan view. As a result, the opening 110a also has a substantially triangular shape. The triangular shape of the opening 110a is a shape (fan shape) that extends from the back side (operation unit side) to the front side. Further, a return member 118 is provided at the edge on the right side surface of the opening 110a so as to protrude toward the inside of the capturing part 110 over substantially the entire area. The return member 118 is configured such that an angle θ2 formed with the inner peripheral surface of the fifth panel 115 is slightly acute (see FIG. 8). Similarly, a barb 119 is provided on the left side edge of the opening 110a so as to protrude toward the inside of the capturing part 110 over substantially the entire area. The return member 119 is configured such that an angle θ3 formed with the inner peripheral surface of the sixth panel 116 is slightly acute (see FIG. 8).

  On the other hand, the edge (upper edge of the first panel 111) constituting the front side of the opening 110a is not provided with a return member, and instead, the cross section extends over substantially the entire area on the inner peripheral surface side of the edge. A rod-shaped guide member 120 configured to have a triangular shape is mounted (see FIG. 7).

  The operation unit includes a handle bar 142 having a round cross section and a floating body 144 connected to the tip thereof. The inside of the floating body 144 is hollow, and even when dropped in water, the floating body 144 can float without sinking. Note that the handle bar 142 may be configured as a telescopic structure.

<Manufacturing method of capture part>
In this embodiment, the capture unit main body and the return members 118 and 119 are formed by die-cutting a single transparent acrylic plate (thickness 1 mm), and then bending the die-cut acrylic plate and bonding the necessary portions. Manufactured by. Thereafter, the capture unit 110 is completed by the procedure of mounting the guide member 120.

  First, the acrylic plate is punched out into a shape shown in FIG. At that time, folding lines (concave grooves) L1 to L8 for folding simultaneously are formed by embossing. Further, the drain hole 111a and the slits 115a and 116a are formed simultaneously with the die cutting. Furthermore, in this embodiment, not only the seven triangular panels (the first panel 111 to the seventh panel 117) that constitute the capturing unit main body, but also the return members 118 and 119 are simultaneously punched and formed.

  More specifically, an acrylic panel having a shape as shown in FIG. One side of the fourth panel 114 and one side of the seventh panel 117 are continuous across the bending line L1. Further, the other side of the seventh panel 117 and the other side of the fifth panel 115 are continuous with the bending line L2 in between. Furthermore, the other side of the fifth panel 115 and the one side of the second panel 112 are continuous with the folding line L3 interposed therebetween. Further, the other side of the second panel 112 and the one side of the first panel 111 are continuous with the folding line L4 interposed therebetween. Further, the other side of the first panel 111 and the one side of the third panel 113 are continuous with the folding line L5 interposed therebetween. Further, the other side of the third panel 113 and the one side of the sixth panel 116 are continuous with the folding line L6 interposed therebetween. Here, regarding the fifth panel 115, the sixth panel 116, and the seventh panel 117, a part of the apex of the triangle for connecting the joint 140 (see FIG. 10) is intentionally cut off in advance.

  Further, the remaining side of the fifth panel and the return member 118 are continuous with the folding line L7 interposed therebetween. Further, the remaining side of the sixth panel and the return member 119 are continuous with the bending line L8 interposed therebetween.

  The acrylic plate die-cut in such a shape is subsequently bent sequentially as shown in FIG. 9 (b) → FIG. 9 (c). Here, the folding lines L7 and L8 are first bent. That is, the two return members 118 and 119 are bent. In addition, these bend | folds so that the side in which each bending line L1-L9 is formed turns inside. If folded in the opposite direction, the panel may break.

  Finally, the panels that come into contact by bending are bonded together with an adhesive. More specifically, the side 114a of the fourth panel 114 and the side 112a of the second panel 112 are bonded, the side 114b of the fourth panel 114 and the side 113a of the third panel 113 are bonded, and the side of the sixth panel 116 116a and the side 117a of the seventh panel 117 are bonded.

  As described above, since the capturing unit 110 of the present embodiment is configured by bending a single acrylic plate, a bonding portion by an adhesive is sufficient. That is, the possibility of water leakage due to an adhesion error can be suppressed to a low level, and since there are few adhesion portions themselves, it is possible to minimize the deterioration of the design properties due to the “extruding” of the adhesive.

  Finally, as shown in FIG. 10, the guide member 120 is attached and attached to the inner peripheral surface of the upper edge portion of the first panel 111. Further, the joint 140 is bonded and connected to the back side of the capturing part main body, and one end of the handle bar 142 is press-fitted to the insertion part 140a formed in the joint 140 to complete.

<Action and function of the trap>
The trap 100 according to the present invention uses the handle bar 142 portion and puts the trap 110 into a water tank. Although not shown in the figure, for example, when there are a plurality of aquatic organisms reared and bred in an aquarium, a tool suitable for selecting a specific one of them and transferring it to another aquarium Become.

  The capture unit 110 is placed in the water tank, and a specific one is operated to be accommodated in the capture unit 110 through the opening 110a. At this time, in the catching tool 110 according to the present invention, the opening 110a is formed wide so that it has a triangular shape. Therefore, it is easy to capture a specific animal. In particular, since the opening 110a is configured to expand from the plane side to the front side, it is easy to capture aquatic organisms located near the bottom of the aquarium. Further, since a plurality of slits 115 and 116 are formed on both side surfaces of the capture unit 110, even when the capture unit 110 is moved in the horizontal direction (left and right direction) in a state of being put in water, the slits are concerned. Since water is drained from the water to some extent, water resistance is low. That is, it is difficult to cause turbulence of the water flow in the water tank, and the laid soil or the like is less likely to rise.

  In addition, since a guide member having a triangular cross section is mounted on the inner peripheral surface of the upper edge of the first panel 111, the first panel is particularly suitable for capturing specific aquatic organisms located on the bottom surface in the aquarium. It is possible to prevent aquatic organisms from being sandwiched between the upper edge portion of 111 and the inner peripheral surface of the water tank.

  In addition, since the capture unit 110 and the like are all made of a transparent acrylic material, in addition to being able to easily grasp the aquatic organisms to be captured, it is also possible to appreciate the captured aquatic organisms from a 360 ° preferred direction. It is.

  Furthermore, even when the capture device 100 is taken out of the water tank after the capture, water remains in the capture portion 110 up to a certain height (for example, up to the position where the drain hole 111a is formed). The aquatic organisms can be immersed in this remaining water (see FIG. 11). As a result, the aquatic organisms will not be exposed unnecessarily, so they will not jump out of the capture unit 110, and since they are not using a net, the aquatic organisms will not be entangled and damaged. Furthermore, even if an aquatic organism tries to jump out, since the return members 118 and 119 are provided at the edge of the opening 110a, it is unlikely that the aquatic organism will jump out of the capture unit 110 by hitting the return members 118 and 119.

  In the capturing tool 100, a floating body 144 is provided at the upper end of the handle bar 142. By providing the floating body 144, even if the capturing device 100 is dropped into the water tank, the entire capturing device 100 does not sink to the bottom of the water tank. That is, even when the body falls down, at least the floating body 142 has a face on the surface of the water, so that the catching tool 100 can be picked up without getting the hands wet. In addition, it is not necessary to put your hand close to the soil laid in the aquarium, so the water in the aquarium will not be rolled up due to disturbance of the water flow when you put your hand in, and the water in the aquarium may be inadvertently turbid No.

  Moreover, in the trap 100, the whole is comprised with the acrylic material. Especially in aquariums that handle ornamental fish, lighting for ornamental fish (often contains ultraviolet rays for growing aquatic plants) is often used to improve the appearance, but acrylic materials are illumination lamps. It is durable and suitable for light irradiation. In addition, there are many cases where there is a restriction on the space for placing the capture device 100 in the water tank, such as when the water tank is placed one above the other. For example, if the handle bar 142 is made of an acrylic material, a considerable amount Since it can withstand the curved state, the handle bar 142 can be bent and placed in the water tank even in a narrow space, which is convenient.

  Moreover, the material which comprises the trap 100 is not limited to a colorless and transparent acryl, A color may be sufficient, and translucent, opaque, and a pattern etc. may be attached | subjected. Furthermore, it is of course possible to change the material as required, such as resin other than acrylic, wood, metal, etc. In particular, when catching highly aquatic aquatic organisms, it is desirable that the catching device itself be so aesthetically pleasing that it can withstand viewing, so that it can be used in various color variations and design variations.

  In the above description, the panel cut by the capture unit 110 is bent. However, it can be formed into a “shape after being folded from the beginning” by using various resin molding techniques.
