Description

  The present invention relates to a portable tamo-net, especially when fishing is not used, such as mountain stream fishing, fishing for cormorant fishing, or artificial bait fishing from the land, where the angler moves frequently while searching for points where fish can be caught. The present invention relates to a portable tamo net that is compactly stored and easy to carry and can be used with one hand.

  For herabuna fishing that does not move very much by deciding a fishing seat in one place or boat fishing that does not require the angler to walk on their own, the fish net for taking in the fish can be used in advance and placed in the vicinity. However, in fishing where the angler himself moves frequently looking for fishing points, such as mountain stream fishing, lure fishing from the land, fly fishing, etc., the tamo net is compactly stored and carried by the angler. A tamo net that can be used is convenient.

  To meet such needs, as shown in FIG. 7 (A), the storage cylinder 43 storing the tamo net 1D is fitted to the end of the base part of the swing bar, and folded as shown in FIG. 7 (B). The tamo net 1D is pulled out from the storage cylinder 43 and used by expanding the arm members 40a, 40b in a V shape around the hinge structure 42a on the base end side of the net portion 40 at the distal end side of the handle 42. This is proposed in Japanese Patent Laid-Open No. 9-113.

  This tamo net 1D is stored compactly in a folded state in the storage cylinder 43 fitted to the base end side of the swing bar when not in use, and is pulled out during use and attached to the opening of the storage cylinder 43 as a tamo net. Since it is in a usable state, it is characterized by excellent portability during storage. However, in mountain stream fishing, lure fishing, and the like, it is common to open the tamo net just before taking in the fish so that it does not get in the way when moving in the rocks or in the cage or operating the kite.

  Therefore, the operation for releasing the fixed state of the tamo net 1D that is housed and fixed in the storage cylinder 43 and making it usable is extremely difficult in a posture in which a fish is hung and the rod is operated with one hand. There is a problem that there is a large risk of escaping the fish that is hung up because it is easy and time-consuming before it can be used.

  To solve this problem, as shown in FIG. 8 (A), a hinge structure 52a provided with a torsion spring supports the arm members 50a and 50b in a V shape in the expanding direction and is supported on the tip end side of the handle 52. The net portion 50 to which 2E is attached is inserted into the sheath body 53 as a closed state while the connecting portions of the pair of distal arm members 51a and 51b connecting both distal ends of the arm members 50a and 50b are folded in a folding manner. Thus, a tamo net 1E, which is compactly stored, is proposed in Japanese Utility Model No. 311270.

  The tamo net 1E having such a configuration does not interfere with carrying by storing the net portion 50 in the sheath body 53, and simply holds the handle 52 and pulls it out of the sheath body 53 just before the fish is taken in. Is automatically expanded into a V-shape and can be used, so that it has excellent operability. In addition, the arm member 50a, 50b can be telescopically extended so that the inner diameter of the net portion 50 can be made as large as possible while keeping the overall size of the tamo- net 1E compact when stored. In conjunction with the pulling-out operation from the sheath body 53, it is automatically extended by a spring.

However, by making the arm members 50a and 50b extendable and contractible in this way, the inner space of the bag-like portion has a margin so that the bag-like portion on the edge side of the net 2E for attaching to the arm member 50a can be compressed into a gather shape when stored. The mesh 2E is bulky as a whole and the smartness of the appearance is impaired, and the inner diameter of the sheath body 53 needs to be increased so that this portion can be smoothly inserted and removed, and the sheath body 53 is excessive. As a result, portability is impaired. On the other hand, if the net unit 50 is made small in order to ensure portability, this time, the fish that can be handled is limited to small ones, and the function as a tamo net tends to be insufficient.
JP-A-9-113 Noto 311270 Publication

  An object of the present invention is to solve the above-described problems, and it is an object of the present invention to provide a portable tammo net with excellent portability while ensuring operability and functionality.

  Therefore, the present invention has a hinge structure in which the base end side is connected with the two arm members biased in the expanding direction at the distal end side, and a net is attached to the frame including the arm member. Portable, which is supported by the tip of the handle and is closed from the state where the two arm members are expanded in a V-shape when in use, so that the mesh can be folded and stored. In the tamo-net, the handle portion is configured by a substantially cylindrical member having a slide hole inside and a tip end side being an open end, and includes a slider slidably disposed in the slide hole. The hinge structure part of the mesh part is attached to the distal end side, and the proximal end side is pressed by a coil spring. When the coil spring is not in use, the slider is pushed into the bottom side of the slide hole while being compressed, and is connected by a predetermined locking means. Stopping and expanding both arm members on the inner peripheral surface of the slide hole It is assumed that at least a part of the mesh part is accommodated in the handle part while being regulated, and the slider is moved to the opening end side of the slide hole by the elastic repulsive force of the coil spring by releasing the locked state during use. Escapes from the slide hole and opens the net.

  In this way, the angler folds the net part into the handle part that grips the tamo net and stores it, so that the storage state is compact and the portability is excellent as much as it is pushed into the handle part and inserted. In addition to this, only by releasing the locking means by operating the release button with the finger of the hand holding the handle, the net is pulled out of the slide hole by being biased by the coil spring. As a result, both arm members urged by an elastic member or the like are expanded and the net portion is quickly and automatically opened, so that the operability is extremely excellent.

  Further, the frame body is connected by connecting the distal ends of both arm members with a pair of distal arm members connected by a predetermined hinge structure, and the arms are folded at the hinge structure portion of the distal arm member during storage. If the net part is folded between the members to fold the net part, the net part can be enlarged without increasing the size during storage, and the hanging part on the tip side of the net by the folding operation is an arm member The net part can be easily accommodated in the slide hole without being drawn to the base end and protruding outside.

  In this case, if the elastic member is provided in the connecting portion between the arm member and the tip arm member in such a manner that the tip end side of the tip arm member is expanded, the mesh portion is extended in the axial direction of the handle portion to increase the size. Even if it is changed, the expansion operation is easy to ensure smoothness.

  Furthermore, the net part of the portable tamo net described above is in an exposed state in which a part of the tip side does not fit inside the slide hole when stored in the handle part, and this exposed part is inserted into a substantially cylindrical sheath body. If all the nets are stored, the stroke width of the slider is reduced, and the nets can be stored and ejected more easily, and the nets can be opened and closed more smoothly. In this case, a connecting structure for connecting and fixing the sheath opening end side and the handle opening end side is provided, and this connecting structure also serves as a locking means for locking the slider to the storage position. If it does, the net | network part will be opened only by canceling | releasing the connection state and pulling out from a sheath body.

  In addition, in this case, the connection structure is a luer lock structure comprising a combination of an engagement groove having a predetermined length provided on the outer peripheral surface on the distal end side of the handle portion and the inner peripheral surface on the distal end portion of the sheath portion, and an engagement convex portion corresponding thereto. If it can be attached / detached by twisting less than a half turn in the circumferential direction, the operability will be further improved, and the angler's outer periphery will be secured to the angler's attachment. If the locking hook is provided, it can be carried only by being locked to an attachment such as a belt, and the mesh portion can be easily opened by pulling out the mesh portion with one hand.

  According to the present invention, when the screen is not in use, it is stored in a state where the mesh portion is pushed into the handle portion, and when used, it escapes out of the handle portion and automatically opens. It can be made excellent.

  The best mode for carrying out the present invention will be described below with reference to the drawings. 1 and 2 show a portable tamo- net 1A according to the first embodiment of the present invention. Referring to the longitudinal sectional view of the portable tamo- net 1A in FIG. 1 (A) when not in use, the portable tamo-net 1A of the present embodiment includes arm members 10a and 10b and a net attached to them. The net portion 10 composed of 2A (indicated by a one-dot chain line and a mesh pattern) is characterized in that it is pushed into the handle portion 5 which is a portion gripped by the angler and is completely stored.

  The handle 5 is formed of a cylindrical member 15 made of a material that can be easily processed, such as plastic, having a slide hole 15a therein and having a distal end open, and the outer peripheral surface is substantially in close contact with the inner peripheral surface of the slide hole 15a. The slider 12 is formed of a substantially columnar member that is slidably inserted in the length direction. The slider 12 has a hinge structure 12a portion attached to and supported by a hinged connection between the proximal ends of the two arm members 10a and 10b which are narrow strips and elastically deformable in the thickness direction on the distal end side. ing.

  Both arm members 10a and 10b are hinged so that the front end side can be opened and closed with the hinge structure 12a as the center, and the front end side of the arm members 10a and 10b is formed in a V shape by a torsion spring 122 interposed in the hinge structure 12a portion. The arm member 10a, 10b is closed against the urging force and the arm member 10a, 10b is closed and accommodated in the slide hole 15a, so that the inner peripheral surface of the slide hole 15a is the side surface of the arm member 10a, 10b. The movement in the expanding direction is restricted by contacting with.

  The arm members 10a and 10b are provided with hook-shaped members 100a and 100b which are formed of a resin or the like and are substantially bowl-shaped and have a large tip-end side, and are connected between the hook-shaped members 100a and 100b. The string member 18 is suspended from the door, and the interval is restricted so as not to open beyond a predetermined width. The saddle-like members 100a and 100b have their front end surfaces substantially flush with the open ends of the slide holes 15a in the state in which the mesh portion 10 is housed, and the widths of the portions that are in close contact in parallel on the front end sides are the slide holes 15a. A part of the opening portion of the slide hole 15a is sealed to substantially coincide with the inner diameter of the slide hole 15a.

Then, the seesaw member 150 that constitutes a part of the locking means that locks the slider 12 so as to be held in the pushed-in position has a locking hole 15b in which the engagement claw 151 on the distal end side is formed from the outer peripheral side of the handle portion 5. The base end side is lifted by a spring 153 and engaged with an engagement groove 111 provided on the side surface of one hook-shaped member 100a, and the slider 12 is fastened and locked at this position.

  That is, in this state, the slider 12 is pressed by the coil spring 19 interposed between the bottom end of the slider 12 and the bottom surface of the slide hole 15a and biased in the protruding direction. 12 is pushed into the bottom of the slide hole 15a by the above-mentioned locking means, and is accommodated in the slide hole 15a while being restricted so that the net 10 is not opened.

  With reference to the longitudinal sectional view showing the state of the portable tamo net 1A in FIG. 1B, the locked state is released by pressing the release button 152 on the base end side of the seesaw member 150, and the slider 12 is After being urged by the coil spring 19 and sliding along the axis in the slide hole 15a, the tip end surface is flush with the open end surface of the slide hole 15a and stopped. As shown in the enlarged partial view, this is in close contact with the inclined surface 15c of the outer peripheral surface near the tip of the slider 12 formed so as to coincide with the inclined surface 15c having the opening side of the slide hole 15a formed in an inverted taper shape. This is because the sliding stops at that point. In this state, since the inclined surface 120c is fitted to the inclined surface 15c, a predetermined fixing force is applied to the slider 12.

  Further, as shown in the figure, the net 2A is attached to and supported by a frame constituted by both arm members 10a and 10b and the string member 18 so as to maintain a predetermined opening shape. Is sewn into a bag shape (not shown), and both arm members 10a and 10b and the string member 18 are inserted into the bag. In the hinge structure 12a, a torsion spring 124 is interposed by urging the distal end side of both arm members 10a and 10b around the shaft 124 in the expanding direction, but both arm members 10a and 10b around the shaft 124 are interposed. Is supported by an annular peripheral wall 121 projecting from the tip end surface of the slider 12 so that the periphery of the hinge structure 12a is surrounded.

  Referring to FIG. 2 showing an enlarged bottom view of FIG. 1 (A), the handle portion 5 of the portable tamo- net 1A is not completely circular in cross-sectional shape, but is rounded to chamfer each corner of a triangle. It is shaped like a side curved in the centrifugal direction. This prevents the slider 12 from rotating in the circumferential direction in the slide hole 15a, and also changes the direction of the net mouth of the net portion 10 only by the feeling that the angler holds the handle portion 5. This is so that it can be grasped. As can be seen from the figure, the tip surfaces of the two hook-like members 100a and 100b have gap portions without blocking the openings of the slide holes 15a. It is provided to push in the excess part that did not exist.

  The portable tamo- net 1A of the present embodiment is configured as described above, and is pushed into the handle 5 in a state in which the mesh 10 is folded when the mesh 10 is stored, and is completely packaged. It is characterized by the fact that the net 10 protrudes and can be expanded and used by simply pressing the release button 152. That is, the total length during storage is shortened by the amount stored in the mesh portion 10 in the handle portion 5, and excellent portability is exhibited.

  In addition, with such a configuration, it is possible to hold the fish with the hand that does not have the sword just before taking in the fish, and to easily expand the net 10 with the fingers of the gripped hand, It is extremely excellent in operability. Furthermore, since it is light and it is easy to provide the larger net | network part 10 from such a compact and simple structure, the outstanding functionality can be exhibited.

  FIG. 3 shows a portable tamo- net 1B according to the second embodiment of the present invention. As shown in FIG. 3 (A), the portable tamo net 1B has substantially the same configuration as the above-described portable tamo net 1A, but a string member that connects and connects the distal ends of the arm members 20a and 20b. Instead of 18, a pair of narrow end-shaped arm members 21 a and 21 b made of elastic steel or the like are connected by a hinge structure 202, and the base ends thereof are hinged to the arm members 20 a and 20 b, respectively. The distal end arm members 21a and 21b are folded between the arm members 20a and 20b in a folding manner during storage.

  Referring to the enlarged partial view of the flange member 200a on the distal end side of the arm member 20a in FIG. 4, as shown in the figure, the distal arm member 21a has a torsion spring 212 interposed on the shaft 215 portion of the flange member 200a. The arm member 20a is connected to the distal end side in a state of being biased in the direction of expanding the distal end side, and the other distal end arm member 21b is the same. For this reason, as the folded net portion 20 moves out of the slide hole 15a, the portion ahead of the both end arm members 21a and 21b is also automatically expanded.

  Referring to the longitudinal sectional view of the portable tamo net 1B in FIG. 3 (B) in use, the tip arm members 21a and 21b provided with the torsion springs 215 and 215 are as described above. The string member 18 is larger than the string member 18 in the axial direction of the handle 5 and expands toward the tip side. In addition, by supporting the tip side of the net portion 20 with a steel material instead of a string material in this way, the shape retention force as the frame of the portion is also reinforced.

  Accordingly, even when the size is the same as that of the portable tamo- net 1A described above, the net portion 20 opens wide by the length X when expanded, and the form of the portion connecting the arm members 20a and 20b is stable. Therefore, the functionality is further improved.

  Further, in the first embodiment described above, the portion of the net 2A that hangs down near the tip of the net 2A is left behind and is difficult to store, but as shown in the side view of FIG. Since the tip half of the net 2B is bent together with the hinge structure 202 and pulled toward the base end side of the arm members 20a and 20b, it is easy to fit in the sliding hole 15a as shown in FIG.

  FIG. 6 shows a portable tamo- net 1C according to the third embodiment of the present invention. Similarly to the portable tamo net 1B of the second embodiment described above, the portable armature net 1C is also provided with the tip arm members 21a and 21b being folded, and connecting the arm members 20a and 20b at the distal end side. ing. However, in the present embodiment, the handle 6 is composed of the cylindrical member 16 that is approximately half the length of the portable tamo net 1B, and the tip half of the mesh 20 that cannot be stored and is exposed from the slide hole 16a It is characterized in that it is inserted into a sheath body 17 separate from the part 6 and brought into a storage state.

  The sheath body 17 is formed of a cylindrical member, has an insertion hole 17a having a diameter larger than that of the handle portion 6, and can insert both ends of the handle portion 6 from the opening portion to connect both members. The sheath body 17 has substantially the same length as the handle 6 and has a bottom wall, and the hook-like members 200a and 200b on the front end side are in a state where all the exposed portions of the mesh portion 20 are stored. It comes into contact with the bottom wall. A luer lock type connecting structure is provided between the outer peripheral surface of the handle portion 6 and the inner peripheral surface of the sheath body 17, and both members can be fixed and fixed only by twisting about a quarter of a turn in the circumferential direction. Can be released.

  By connecting and fixing the handle portion 6 and the sheath body 17 with such a configuration, both end surfaces of the hook-like members 200a and 200b that become the tip portions when the mesh portion 20 is stored are formed on the storage holes 17a. Since the slider 12 abuts on the bottom wall and is locked at this position and locked, the seesaw member 150 or the like is not necessary for serving as a locking means for the slider 12.

  With reference to the front view showing the state of use of the portable tamo net 1C of FIG. (B), after the angler has grasped the handle 6 and twisted about one-quarter, the locked state is released. Since the net part 20 protrudes and expands automatically just by pulling out the net part 20, it is characterized in that it can be quickly and easily put into use without the need to search and press the release button. ing.

  Also, as shown in the figure, if a locking hook 171 is provided on the outer peripheral surface of the sheath body 17 so as to be locked to an angler's belt or the like, it becomes extremely convenient for carrying. Furthermore, by fixing the sheath body 17 to the angler side in this way, it can be easily used with a simple operation such as pulling out a sword only with the other hand that does not have a rod when taking in a fish. State.

  As an example of the connection structure, for example, as shown in the figure, engagement grooves 162 of a predetermined length are formed at predetermined intervals in the circumferential direction on the outer peripheral surface side of the rounded chamfered corner portion of the handle portion 6 having a substantially triangular cross section. The engagement protrusions 172 having a predetermined length may be provided at predetermined intervals at corresponding positions on the inner peripheral surface of the housing hole 17a of the sheath body 17 having a circular cross section. Further, in common with all the above-described embodiments, a large mesh such as a lure landing net is not likely to be damaged due to entanglement with arm members or the like constituting the frame. Not suitable, for example, a relatively small mesh such as a mountain stream tamo net is suitable.

  As described above, the portable tamo net has been extremely excellent in portability while ensuring operability and functionality according to the present invention.
