Description

  The present invention relates to a hand-held capture device for capturing creatures such as insects, fish, and small animals.

  Insect catching nets for capturing insects are well known. However, conventional insect catching nets keep the opening of the net provided at the tip of the hand-held cocoon open, so once the insect nets are fine. Even if covered, the insect often escapes from the opening until the insect is secured by hand.

Therefore, the following Patent Documents 1 and 2 propose a trapping tool that allows an opening of a net to be closed by an operation on the hand side of the cage after an insect or the like enters the net. In Patent Document 1, the opening of the mesh can be closed by surrounding the opening of the mesh with a wire and pulling the wire on the proximal side of the rod. On the other hand, the thing of patent document 2 attaches the rake-shaped framework which the inside side bulges to the front-end | tip of a cage | hook open | closed freely and closes circularly, and attached the net | network to this framework. Although how to close the framework is not described in detail in Patent Document 2, if it is inferred from the description of FIG. 1, the string-like material passed through the heel is pulled on the hand side. It seems that the framework is closed by this, and the net is thereby closed.
Japanese Patent Laid-Open No. 10-234285 JP 2004-222696 A

  However, in all of the above-mentioned conventional methods, as the operation for closing the opening of the mesh, the string-like material has to be pulled by a predetermined stroke on the proximal side of the bag, so that the opening of the mesh can be instantaneously and reliably secured. It is also difficult to close the wing, and insects may escape before the opening is completely closed. Further, pulling the string-like material with the other hand while holding the heel in a fixed posture with one hand so as not to miss insects or the like also has problems such as poor operability.

  The present invention has been made in view of the circumstances as described above, and an object of the present invention is to provide a handheld catcher that can catch a catch once entering the net without missing it.

  In order to solve the above-mentioned problems, a hand-held catch device according to the present invention is a hand-held scissors and a net provided at the tip of the scissors, and has a mouth that can be opened and closed. A closed net, net driving means for supplying power for automatically changing the shape of the net from an open state to a closed state, and the net driving means at the base end of the bag And an operating member that can be controlled on the side (Claim 1).

  According to the present invention, the user of the capture tool operates the operation member on the rear end side of the heel after a catch such as an insect enters the net from the mouth. The mesh driving means can be operated to automatically close the mouth of the mesh. For this reason, once the captured object enters the net, it cannot escape from the net, and the captured object can be reliably captured. In addition, by operating the operation member, the net is automatically deformed to a state where the mouth is closed, so that operability is also good.

  In the present invention, the net driving means is usually a power accumulation type such as rubber or a spring, but an electric type or the like can also be adopted.

  As a preferred embodiment, the mesh driving means is an urging member that constantly applies a restoring force to the mesh so that the mouth is closed, and the operation member is applied to the urging force of the urging member. Accordingly, the net can be held in a state where the mouth is open, and the holding in the state where the mouth is open can be released on the rear end side of the bag. ).

  According to the above configuration, the opening of the net is normally closed by the urging force of the urging member. The user of the capture tool operates the operation member to shift or deform the net into a state where the mouth is opened against the urging force of the urging member and hold the net in that state. Then, after a catch such as an insect enters from the mouth into the net, if the release operation of releasing the mouth of the net is performed on the rear end side of the moth, the biasing is performed. The net is automatically and instantaneously restored to the closed state by the biasing force of the member. Since the mouth is closed, the catch cannot escape from the net, and the catch can be reliably caught.

  In the handheld catcher, when the hand is released from the operation member, the opening of the mesh may be automatically closed by the urging force of the urging member, and the mouth is opened. It is also possible to provide a lock mechanism that can be released and restrained against the urging force of the urging member so as to remain in the operation position corresponding to (3). In the latter case, since the operation member stays at the operation position corresponding to the opened state by the lock mechanism, the operation member is restrained by hand in order to maintain the opened state. It is not necessary to keep it, which is preferable.

  As a preferred embodiment, the frame includes a frame that supports the net at the tip portion of the ridge, and the frame moves relative to the fixed frame member fixed to the ridge and the fixed frame member. And a movable frame member that opens and closes the mouth of the net.

  As another preferred embodiment, a sealing member that enhances the sealing performance in the closed state of the mouth and prevents escape of the captured object can be provided (Claim 5).

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is an overall perspective view of a handheld catcher according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the catcher of FIG.

  As shown in FIG. 1, the handheld trap 1 according to the present embodiment includes a hand-held scissors 2 and a net 3 provided at the tip 2 a of the scissors 2. The hand-held trap 1 is most commonly used as a net for catching insects. However, by setting the size and strength appropriate for the purpose of use, a net for catching fish and catching small animals can be used. It can also be applied as a net.

  The hook 2 is for the user to operate the net 3 while holding the rear end 2b side in his / her hand. The material of the collar 2 is not limited, but it is preferable to use a plastic pipe or an aluminum pipe from the viewpoints of durability, lightness, ease of processing, and the like. The total length of the cocoon 2 is set to be long, for example, when collecting insects such as cicada, butterfly, and dragonfly, and when used for capturing cockroaches, flies, moths, etc. The length may be set appropriately according to the purpose of use, such as setting it to be short so that it can be easily performed.

  The net 3 is provided with a mouth 4 that can be freely opened and closed, and portions other than the mouth 4 are closed. The net 3 is supported by a frame 5 at the tip 2 a of the heel 2. The frame 5 includes a fixed frame member 6 fixed to the flange 2 and a movable frame member 7 that opens and closes the mouth 4 of the net 3 by moving relative to the fixed frame member 6. Yes. Each of the fixed frame member 6 and the movable frame member 7 can be formed by processing a metal bar or molding it with plastic. However, in order to improve the operability of the rod 2, it is lightweight. Preferably.

  As shown in FIG. 2, the fixed frame member 6 includes a rod-like extension portion 8 that is an attachment portion to the flange 2 and a left and right outward formed integrally with the front end portion of the rod-like extension portion 8. The overhanging portion 9 and a pair of left and right arm portions 10 and 10 extending from the left and right end portions of the overhanging portion 9 to the front of the heel 2 are provided. The fixed frame member 6 is fixed to the flange 2 in a state where the rod-like extending portion 8 is attached to the tip end portion 2a of the flange 2. In the attached state to the flange 2, the fixed frame member 6 has a U-shape with a front portion opened by the overhang portion 9 and the pair of left and right arm portions 10 and 10. The pair of left and right arm portions 10 and 10 are located at equal left and right positions from the distal end portion 2a of the flange 2 and extend in the same length in parallel to each other forward along the length direction of the flange 2. I'm out.

  On the other hand, the movable frame member 7 has a rod-like shape, and is laid between the pair of left and right arm portions 10 and 10 in parallel with the protruding portion 9 of the fixed frame member 6. At both ends of the movable frame member 7, ring-shaped engaging portions 11, 11 are formed that are movable and non-detachable to the pair of left and right arm portions 10, 10. The movable frame member 7 can be freely translated back and forth along the length direction of the pair of left and right arms 10, 10.

  The mouth 4 of the mesh 3 is fixed to the overhang 9 of the fixed frame member 6, the pair of left and right arms 10 and 10, and the movable frame member 7 all around the mouth 4. . Therefore, when the movable frame member 7 is translated in the front-rear direction along the fixed frame member 6, the opening 4 of the net 3 is opened and closed. When the movable frame member 7 is positioned on the most distal end side of the fixed frame member 6, the opening 4 is fully opened (the state of the phantom line in FIG. 1), and the movable frame member 7 is in the fixed frame member 6. When it is located close to the flange 2 until it comes into contact with the overhanging portion 9, the mouth is in a fully closed state (solid line state in FIG. 1).

  The handheld trap 1 includes a net driving means 12 for supplying power for automatically changing the shape of the net 3 from an open state to a closed state, and the net drive means 12. And an operation member 13 that can be controlled on the rear end 2a side of the collar 2.

  As the net driving means 12, a small electric motor or the like for translating the movable frame member 7 back and forth along the fixed frame member 6 is used, and as the operation member 13, the electric motor is controlled. It is also possible to use a switch or the like. However, from the viewpoints of weight reduction, simplification of configuration, difficulty of failure, and cost reduction, specifically, an urging member such as rubber or a spring or an elastic member is used as the mesh driving means 12. Is preferred.

  In the present embodiment, a coil-type tension spring that constantly applies a restoring force to the net 3 to the state where the mouth 4 is closed is employed as the net driving means 12. Specifically, the operation rod 14 as the operation member is inserted into the hollow interior of the rod 2 so as to be movable back and forth. A front end portion 14 a of the operation rod 14 is connected to a central portion in the length direction of the movable frame member 7. On the other hand, the rear end portion 14b of the operation rod 14 is positioned in front of the rear end portion 2b of the rod 2. The tension spring 12 is interposed between the plug bolt 17 that closes the rear end opening 16 of the grip pipe 15 that forms the rear portion of the flange 2 and the rear end portion 14b of the operation rod 14. Yes. The tension spring 12 constantly urges the operation rod 14 toward the rear of the rod 2. As a result, the operation rod 14 is normally held at a position where the movable frame member 7 is in contact with the protruding portion 9 of the fixed frame member 6. Therefore, at the normal time, the opening 4 of the mesh 3 is held in the fully closed state by the biasing force of the tension spring 12.

  A slit 18 extending in the length direction of the flange 2 is formed on the rear side of the flange 2 at a position in front of the grip pipe 15. The length of the slit 18 is the same as or longer than the movable distance of the movable frame member 7 in the front-rear direction on the fixed frame member 6. On the side of the rear end portion 14b of the operation rod 14, a knob 19 constituting the operation member 13 together with the operation rod 14 is fixed by an appropriate method such as screwing. Exposed to the outside.

  As shown in FIG. 1, the knob 19 is at the rearmost position in the slit 18 when the mouth 4 of the mesh 3 is fully closed by the urging force of the tension spring 12. When the user puts his finger on the knob 19 and moves the knob 19 along the slit 18 to the front of the rod 2, the operation rod 14 moves forward in the rod 2. The movable frame member 7 is translated forward on the fixed frame member 6. As a result, the mouth 4 of the net 3 is opened. When the mouth 4 of the net 3 is fully opened, the knob 19 comes to the foremost position in the slit 18. The forward movement limit of the movable frame member 7 is defined by bringing the knob 19 into contact with the front end portion 18a of the slit 18, or the pair of left and right arm portions 10 of the fixed frame member 6. , 10 may be defined by forming the retaining frame 20 of the movable frame member 7 at the front end portion.

  The user of the trap 1 moves the knob 19 forward against the urging force of the tension spring 12, and moves the knob 19 to the operation position where the mouth 4 of the net 3 is fully opened. Hold with your finger. Then, after the net 3 is covered with a catch target such as an insect, the knob 19 is released. At that moment, the operating rod 14 is pulled back toward the rear end 2b of the rod 2 by the urging force of the tension spring 12, and the mouth 4 of the net 3 is fully closed. Therefore, capture targets such as insects can no longer escape from the net 3, and the user of the capture tool can reliably capture the captured object. By simply releasing the finger from the knob 19, the mouth 4 of the net 3 is instantly and completely closed, so that the operability is excellent. Further, since the tension spring 12 is used as the net driving means, there is an advantage that it can be supplied at a low cost. Even when rubber is used as the net driving means, the same effect as described above can be obtained.

  In addition, the arrangement position of the biasing member for holding the net 3 in a state where the mouth 4 is closed is not limited to the inside of the rear end portion 2b side of the scissors 2, but the front end of the scissors 2 It can also be interposed between the operation rod 14 inside the portion 2a. In this case, a compression coil spring can be used as the urging member as necessary.

  Next, another embodiment of the present invention will be described with reference to FIGS. FIG. 3 is a perspective view of a main part of a hand-held trap 21 according to another embodiment of the present invention, and FIG. 4 is an exploded perspective view of FIG.

  The features of the embodiment of FIGS. 3 and 4, that is, the difference from that of FIGS. 1 and 2, is that the tension spring is such that it stays in the operating position corresponding to the opening 4 of the mesh 3. 12 is provided with a lock mechanism 22 which can be released and restrains the knob 19 against the urging force. The other points are the same as in the example of FIGS. 1 and 2, so illustration and description thereof are omitted.

  In this embodiment, as shown in FIG. 3, as a specific component of the lock mechanism 22, a pinch recessed in the circumferential direction of the cylindrical hook 2 at the front end of the slit 23 of the hook 2. A retaining recess 24 is formed. The formation position of the knob stop recess 24 is a position where the opening 4 of the net 3 is fully opened when the knob 19 is locked to the knob stop recess 24. In this case, the knob 19 is attached to the operation rod 25 so as to be rotatable about the axis X of the operation rod 25 inserted through the rod 2. The rotation angle range of the knob 19 may be an angle range necessary for engagement with and disengagement from the knob retaining recess 24.

  That is, as shown in FIG. 4, for example, a narrow diameter portion 26 is formed at the rear end portion of the operation rod 25 that constitutes the operation member 13 together with the knob 19, and relative rotation with respect to the small diameter portion 26 is performed. A free cylindrical portion 27 is integrally coupled to the knob 19, and the small diameter portion 26 is inserted into the cylindrical portion 27. By providing the small diameter portion 26, the step portion 28 formed at the rear portion of the operation rod 25 prevents the cylindrical portion 27 from moving forward on the operation rod 25. A screw 29 for fastening the tension spring 12 is coupled to the rear end portion 26b of the small-diameter portion 26. The screw 29 is preferably provided with a stopper 30 for preventing the cylindrical portion 27 from coming out of the small diameter portion 26.

  According to the present embodiment, the user operates the knob 19 to move forward against the urging force of the tension spring 12, and moves the knob 19 at the position of the knob-holding recess 24. The knob 19 is locked to the knob retaining recess 24. By this operation, the mouth 4 of the net 3 is fully opened, and even when the user releases the finger from the knob 19, the mouth 4 is kept fully open. Then, after the net 3 is covered with a catch target such as an insect, when the knob 19 is detached from the knob locking recess 24 with a finger, the operating rod 25 is urged by the urging force of the tension spring 12 at that moment. Is pulled back toward the rear end 2b side of the basket 2, and the mouth 4 of the net 3 is fully closed. Therefore, capture targets such as insects can no longer escape from the net 3, and the user can reliably capture the captured matter.

  According to this embodiment, the same effects as those of FIGS. 1 and 2 can be obtained, and the user holds the knob 19 with a finger in order to maintain the mouth 4 of the net 3 fully open. Therefore, there is an advantage that the operation can be easily performed with one hand and the operability is further improved.

  In addition, as another example of a configuration for enabling the knob 19 to be rotated so as to be locked to the knob stop recess 24, the knob 19 is arranged with respect to the operation rod 14 as shown in FIG. It is also possible to adopt a method in which a rotatable portion is interposed between the operation rod 14 and a part of the operation rod 14 or a connecting portion between the operation rod 14 and the movable frame portion 7.

  As another embodiment, as shown in FIG. 5, a sealing member 31 that enhances the sealing performance in the closed state of the mouth 4 and prevents the captured object from escaping may be provided. Specifically, for example, the seal member 31 may be provided on at least one of the projecting portion 9 of the fixed frame member 6 and the movable frame member 7. You can also. When it is provided only on either one, it is preferably provided on the movable frame member 7 side.

  The seal member 31 can be made of a flexible rubber that is fixed to the tip of the dust ring, and is fixed to the overhanging portion 9 or the movable frame member 7 using, for example, an adhesive. do it. When the rubber seal member 31 is fixed to both the projecting portion 9 and the movable frame member 7, the seal members 31 come into close contact with each other in the closed state of the mouth 4, and the sealing performance is improved. Rise. This prevents the catch from escaping. If a flexible rubber is used as the sealing member 31, it is preferable that the catch is prevented from being crushed when the mouth 4 is closed.

  Other examples of the sealing member 31 include a sponge and a brush-like member. In any case, as in the case of a rubber-made one, it is only necessary to attach one having a length substantially the same as the full length of the overhanging portion 9 or the movable frame member 7 to them. In the case of a sponge or brush-like sealing member, the catch can be prevented from escaping, as is the case with rubber, and the catch can be prevented from being crushed when the mouth 4 is closed.
