Description

  The present invention relates to a capture net that captures a wide variety of organisms, such as large ornamental fish, ancient fish, small animals, amphibians, etc. safely, quickly and intactly.

Conventionally, for capturing small animals such as ornamental fish and pets, a so-called catch net (rake net) is known in which a frame is fixed to the tip of a cage and a net is attached to the frame. Also, in catching large luxury fish, a net having a long net part of the catch net and a free net part of the net is also used.
Japanese Utility Model Publication No. 6-61067

  However, the method of catching with a rake net is fine for small fish and small pets. There was a problem. Moreover, since scales are caught on the net and peeled off, there is a problem that the commercial value is remarkably lowered.

  In addition, ornamental fish tanks have become larger, and ornamental fish are usually placed above the adult's waist, so that fish can be inserted into or removed from the aquarium using unstable scaffolds such as stepladders. Work at a high altitude. In addition, when the fish is driven into the cylindrical net, the work of putting the hand in the water and lifting it by hand while squeezing the end of the other net is very heavy. Since it is carried out by holding the end portion which is difficult to grasp, it is not preferable because it is a dangerous work with a poor balance at a high place. These conventional cylindrical nets use a net with a soft and small mesh for the purpose of not damaging the fish, so if the captured large fish goes wild, the net will break and there is a high possibility that the captured fish will be dropped. In particular, the captured large fish will be held and transported, which requires work and skill. Moreover, when the capture has poison or is ferocious, the capture net of the above-mentioned patent document 1 cannot be used from the viewpoint of safety.

  In view of such circumstances, the present inventors have completed the present invention as a result of intensive studies to provide a capture net that can be used safely at high altitudes and can be safely captured and transported without damaging the captured matter. It came to do.

  That is, the present invention is (1) a cylindrical mesh body having a double structure in which the outer side is composed of a reinforced net and the inner side is composed of a soft net, and both ends are opened. Is to provide a capture net.

  In addition, the present invention provides the capture net according to (1) above, wherein the soft net is a net composed of soft fibers that do not damage the captured object.

  In addition, the present invention provides the capture net according to (1) above, wherein the reinforcing net is a net having a strength that is not destroyed by the captured matter.

  Moreover, this invention provides the capture net as described in said (1) characterized by a frame having a holding part.

  The present invention also provides the capture net according to (1) above, wherein a lid with an opening / closing mechanism is attached to a frame at one end of the cylindrical net.

  Also, the present invention provides a lid with an opening / closing function comprising a handle that can be grasped by a hand, a frame body that is open at both ends attached to the tip of the handle, and a lid, and a trigger that opens and closes the lid is pulled. Accordingly, the present invention provides the capture net according to (1) above, which is performed by a coil spring and a link mechanism.

  The trapping net of the present invention can be used safely at high altitudes, such as large luxury fish and piranha, because the open end of the net can be closed at the same position on the left and right without immersing hands in water. Even if it is a dangerous fish, it has the effect that it can be safely captured and transported without damaging the catch. In addition, if the outer and inner nets constituting the catch net are made of a flexible material such as nylon fiber, the frame and the cylindrical net can be handled on a straight line. In other words, there is an advantage that it can be used even when there is only a narrow space in the upper part of the water tank.

  In addition, there is an advantage that it can be used for capturing small animals more safely and efficiently by changing the material of the net or using a lid with an opening / closing function having a remote control function.

Hereinafter, the present invention will be described in more detail.
The capture net of the present invention is a cylindrical net body having a double structure in which the outside is composed of a reinforced net and the inside is a soft net, and both ends are open, and a frame is attached to both ends of the net body. It is a capture net. The outer reinforcing net may be a net having a strength that is not destroyed by the captured matter, and is not particularly limited, but examples include synthetic resins such as nylon, reinforced plastic resins, and wire netting. Etc. is recommended.

  The soft net used in the capture net of the present invention may be a net composed of soft fibers that do not damage the captured matter, and is not particularly limited, but a fine net composed of synthetic resin fibers such as nylon is recommended. The Although the fineness of the net of the net is not unambiguous depending on the object to be captured, when the object to be captured is a fish, it is at least smaller than the shape of the scale held, preferably 1/2 or less, more preferably 1/3. The following are used.

The trapping net of the present invention is a cylindrical net body having a double structure composed of a reinforced net on the outside and a soft net on the inside, and both ends of the open net are provided with frames.
The shape of the frame is not unambiguous depending on the object to be captured, but when targeting fish such as ornamental fish, in the case of a circle, the diameter is about 5 cm to about 80 cm, preferably about 10 cm to about 50 cm. In the case of a triangle or a quadrangle, the length of one side is about 5 cm to about 80 cm, preferably about 10 cm to about 50 cm. The frame body may be composed of anything, but usually metal, specifically iron, copper, stainless steel and the like can be mentioned. Stainless steel wire is recommended because there is no contamination such as rust. The thickness of the line is not particularly limited, but a very thin one is not preferable from the viewpoint of shape stability, and one having a diameter of about 1 mm to about 5 mm is usually used.

  The attachment method to the net body to the frame body may be a known method, and is not particularly limited. For example, the end of the net body is sewn in a cylindrical shape, and the frame body, for example, a metal wire is passed through and fixed to this opening. Examples thereof include a method, a method in which a frame is folded and stitched together, a method in which the frame is fixed with an appropriate adhesive, or a method in which welding is performed by heat.

  In the present invention, the frame may have a gripping portion. The shape of the gripping portion is not particularly limited, but may be any shape as long as it has a gripping portion from the top so that the capture net can be easily used. For example, a hook-like handle may be attached to the upper portion of the frame. In this case, the catch net is immersed in the aquarium with the handle, the fish to be captured is driven from the other frame, and when it is driven, the handle is rotated inward 180 degrees and lifted from the aquarium. By rotating 180 degrees inward, the fish loses its escape, and by quickly lifting it, the fish is wrapped in a soft net and covered with a reinforced net, so it loses freedom, can be transported without being violated or damaged It is.

  Although the capture net of the present invention can be used as it is in the above configuration, it can also be used by attaching a lid with an opening / closing mechanism to the frame at one end of the cylindrical net.

  The structure of the lid with an opening / closing function that is attached to the frame at one end of the cylindrical mesh body is not particularly limited. For example, the lid with the opening / closing function is held by the handle and both ends attached to the tip of the pattern are open. And a structure in which the lid is opened and closed by a coil spring and a link mechanism by pulling a trigger arranged on a handle.

  The capture net of the present invention having a lid with an opening / closing function having such a structure will be described with reference to the drawings. However, the drawings are only one embodiment and do not limit the present invention. In the present invention, FIG. 1 is a side view in which the capture net of the present invention is connected to a lid with an opening / closing mechanism, FIG. 2 is a top view in which the capture net of the present invention is connected to a lid with an opening / closing mechanism, and FIG. The front view which connected the capture net and the lid with the opening / closing mechanism is shown, (1) is the capture net, (2) is the frame and the connection part of the lid with the opening / closing mechanism, and (3) is the capture net A cylindrical net body having both ends opened, (4) and (5) are frames attached to the open end of the double net, (6) and (7) are gripping portions of the frame, (8) Handle handle, (9) Lock device, (10) Lid, (11) Wire, (12) Trigger, (13) Fixed pulley, (14) Link mechanism, ( 15) is a cover net, (16) is a coil spring, and (17) is a lid.

The lid with an opening / closing mechanism of the present invention is formed by attaching frames (4) and (5) to both ends open portions of a cylindrical net body having a double structure of a reinforced net on the outside and a soft net on the inside. It is attached to either frame of the capture net (3). In the figure, hook-shaped gripping parts (6) and (7) are arranged at the upper part of the frames (4) and (5), so that the operability of the capture net and the transportation of the captured capture are safe and secure. Although it has a function of facilitating, the gripping portion is not necessarily essential when the frames (4) and (5) can be gripped and operated directly in capture applications.
When using a lid with an opening / closing mechanism, the lid (17) is attached to the other one of the frames (7), and one of the frames is closed. The lid (17) does not have a remote opening / closing function, and may be in a usage mode directly fixed to the frame (5).
