Description

  The present invention relates to fish scissors. In detail, for example, the present invention relates to a fish scissor for holding and transporting raw fish in a fishing or fresh fish shop.

  It is not easy to grab live fish with human hands. In particular, fish that are toxic to fins and thorns, and fish that secrete a lot of mucus from the surface of the body are even more difficult to grasp. In such cases, fish scissors are used. The basic structure of the fish scissors is that two scissors main bodies are connected to each other by a support shaft so as to be rotatable in the same manner as ordinary paper scissors. The fish is pinched by the front end side portion (hereinafter referred to as a holding portion) from the support shaft by the user gripping a rear portion (hereinafter referred to as a grip operation portion) from the support shaft of the scissors body. The basic difference from the paper scissors is that no blade is formed in the holding portion along the longitudinal direction. Some fish scissors have many teeth aligned instead of blades. The large number of teeth allows the fish to be gripped without sliding down.

  For example, in the fishing scissors disclosed in Japanese Patent Application Laid-Open No. 2008-211986, neither a blade nor teeth are formed in the holding portion on the front end side from the support shaft. The sandwiching portion is formed to be an arc-shaped recess having a large curvature radius so that fish can be easily sandwiched. On the other hand, the scissor device disclosed in Japanese Patent Laid-Open No. 6-328367 is also for holding fish. This publication discloses a scissors device (FIG. 1) in which teeth are formed only in one of a pair of clamping parts, and a scissor device (FIGS. 5 and 6) in which teeth are formed in both clamping parts. ing.

  Usually, the fish scissors are stored in a bag or the like in a closed state and carried by a user or the like. When the fish scissors disclosed in any of the above publications are closed, at least the front ends abut against each other. The sandwiching portions cannot approach each other beyond the position when they are in contact with each other. As a result, fish scissors cannot have a compact shape that is convenient for storage and carrying.

FIG.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  The fish scissors 1 shown in FIGS. 1 to 5 have a pair of scissors main bodies 2U and 2L extending in the front-rear direction. One scissors body 2U is also referred to as an upper body 2U, and the other scissors body 2L is also referred to as a lower body 2L. However, the fish scissors 1 may be used in a state where any of the scissors main bodies 2U and 2L are positioned on the upper side. The scissors body 2U, 2L is a glass fiber added to PA (polyamide), a glass fiber added to ABS resin (acrylonitrile-butadiene-styrene resin), a glass fiber added to POM (polyacetal), It is formed from a material obtained by adding carbon fiber to PA. However, it is not limited to such a material. These scissors main bodies 2U and 2L are connected to each other by a support shaft 3 so as to be rotatable in the vicinity of the rear end portion thereof. The scissors main bodies 2U and 2L are opened and closed with the support shaft 3 as a fulcrum.

  In FIG. 1, the open state between the scissors main bodies 2U and 2L is shown by a solid line, and the closed state is shown by a two-dot chain line. The fish scissors 1 of the present embodiment are configured such that the full opening angle α between the scissors main bodies 2U and 2L is about 30 °. However, the opening is not limited to this. Each scissors main body 2U, 2L has clamping parts 4U, 4L located in the front part, and grip parts 5U, 5L located in the rear part. The clamping parts 4U and 4L are parts for sandwiching fish or the like, and the grip parts 5U and 5L are parts for a human hand to perform a grip operation.

  As shown in FIGS. 2 to 5, the upper and lower scissors main bodies 2U and 2L are both formed in a ship shape. The upper main body 2U has a long top plate 6 and outer walls 8U formed along the left and right side edges of the top plate 6. The lower main body 2 </ b> L includes a long bottom plate 7 and outer walls 8 </ b> L formed along the left and right side edges of the bottom plate 7. Each of the scissors main bodies 2U, 2L has a symmetrical shape with respect to the center line in the front-rear direction.

  A large number of teeth 9U are formed along the lower edge of the clamping portion 4U in the upper outer wall 8U. A large number of teeth 9L are also formed along the upper edge of the clamping portion 4L in the lower outer wall 8L. These teeth 9U, 9L are all triangular in side view, and are all inclined toward the back of each scissors body 2U, 2L. The lower end edge of the upper outer wall 8U and the upper end edge of the lower outer wall 8L are both arcuate concaves having a large curvature radius in the range of the sandwiching portions 4U, 4L. This is to make it easier to pinch fish.

  As shown in FIG. 2, a torsion spring 10 is mounted around the support shaft 3. The torsion spring 10 is mounted so that the upper and lower scissors main bodies 2U and 2L are biased in the opening direction with the support shaft 3 as a fulcrum. A lock member 11 is inserted between the rear ends (rear ends of the scissors body 2U, 2L) of the upper and lower grip portions 5U, 5L connected. The lock member 11 can be moved back and forth between a lock position L for restricting the scissors main bodies 2U and 2L to a fully closed state and an operation position F for allowing an open / close operation. Details of the lock member 11 will be described later.

  As shown in FIGS. 2, 4 and 5, reinforcing ribs 12U and 12L are formed on the upper and lower scissors bodies 2U and 2L, respectively. Each of the reinforcing ribs 12U and 12L is formed along the center line in the longitudinal direction of the upper and lower scissors main bodies 2U and 2L in the inside surrounded by the outer walls 8U and 8L. As a result, the scissors body 2U, 2L has a shape in which the cross section is substantially E-shaped (see FIG. 3). The reinforcing rib is not formed in a predetermined range from the rear ends of the grip portions 5U and 5L. This is to avoid interference with the lock member 11 inserted from the rear ends of the grip portions 5U, 5L. Therefore, in this range, the cross sections of the grip portions 5U and 5L are substantially U-shaped.

  Numerous teeth 13U and 13L are formed on the lower end edge of the reinforcing rib 12U of the upper main body 2 and the upper end edge of the reinforcing rib 12L of the lower main body 2L, respectively. These teeth 13U, 13L are all triangular in side view, and are all inclined toward the front of each scissors body 2U, 2L. That is, the teeth 13U and 13L of the reinforcing ribs 12U and 12L are inclined in the direction opposite to the teeth 9U and 9L of the outer walls 8U and 8L. Thereby, the fish pinched by the fish scissors 1 is hard to slip in either the front or back direction and can be firmly held. The reinforcing rib teeth 13U and 13L may be inclined rearward, and the outer wall teeth 9U and 9L may be inclined forward.

  As shown in FIG. 3, the width of the upper body 2U is larger than the width of the lower body 2L. The upper and lower outer walls 8U and 8L extend in a substantially similar shape. When the upper and lower main bodies 2U and 2L are closed, the left and right outer walls 8L of the lower main body are fitted inside the left and right outer walls 8U of the upper main body. Therefore, the teeth 9U and 9L on the upper and lower outer walls do not contact each other. When the upper and lower outer walls 8U and 8L are fitted to each other, the fish scissors 1 have a compact shape. In order to facilitate this fitting, the left and right outer walls 8L of the lower main body are slightly inclined inward. In order to facilitate this fitting, the teeth 13U and 13L of the upper and lower reinforcing ribs are configured to overlap with each other so as not to contact each other as follows.

  As shown in FIG. 3A, the upper and lower reinforcing ribs 12U and 12L may be formed at positions that coincide with the width direction. In this case, it is preferable that the teeth 13U and 13L of the upper and lower reinforcing ribs are formed at positions where the tooth pitch is increased and the upper and lower teeth 13U and 13L are shifted from each other by a half pitch in the front-rear direction. As a result, when the scissors main bodies 2U and 2L are closed, the upper and lower teeth 13U and 13L are located between the teeth.

  As shown in FIG. 3B, it is also preferable that the upper and lower reinforcing ribs 12U and 12L are formed at positions that do not coincide with the width direction. In this case, when the scissors main bodies 2U and 2L are closed, the upper and lower teeth 13U and 13L do not interfere with each other. With these configurations, the upper and lower outer walls 8U and 8L are easily and deeply fitted to each other, and the fish scissors 1 have a compact shape.

  As shown in FIG. 1, front end teeth 14U and 14L project from the front ends of the sandwiching portions 4U and 4L toward the sandwiching portions 4L and 4U facing each other. The front end teeth 14U and 14L are formed so as to overlap with each other without contacting each other when the sandwiching portions 4U and 4L are closed. With this configuration, the scissors main bodies 2U and 2L come closer to each other when closed, and the fish scissors 1 have a compact shape.

  The upper and lower outer walls 8U, 8L are tall in the range of the clamping portions 4U, 4L where the teeth 9U, 9L are formed. Both the upper and lower clamping parts 4U, 4L are provided with portions where the outer walls 8U, 8L are extremely low, adjacent to the rear of the front end teeth 14U, 14L. By this part, when the clamping parts 4U and 4L are closed, the window part 16 is formed in the both right and left side surfaces of the clamping parts 4U and 4L. By forming the window portion 16, for example, the following advantages can be obtained. A small fish mouth can be easily grasped by the front end teeth 14U and 14L. In addition, when the front end teeth 14U and 14L are engaged with the hanging ring provided on the bag or the wall, the clamping portions 4U and 4L are closed and locked by the lock member 16, thereby Fish scissors 1 can be easily held.

  As shown in FIGS. 1, 4 and 5, the outer walls 8U and 8L near the rear ends of the grip portions 5U and 5L are raised. This range of the outer walls 8U and 8L is referred to as expansion wall portions 15U and 15L. When the scissors main bodies 2U and 2L are closed, the upper and lower extension wall portions 15U and 15L are also fitted. The extension wall portions 15U and 15L are adjacent to the support shaft 3. Therefore, when the scissors main bodies 2U and 2L are opened and closed, the upper and lower extension wall portions 15U and 15L overlap with each other in most of the operation range. Thus, the scissors main bodies 2U and 2L are prevented from being displaced or wobbled in the width direction when being opened and closed. As a result, the outer walls 8U, 8L and the reinforcing ribs 12U, 12L fit smoothly without the teeth 9U, 9L, 13U, 13L of the sandwiching portion abutting each other. The extended wall portions 15U and 15L are so-called guide portions. The extension wall portions 15U and 15L are preferably formed so as to overlap in the entire range from the fully closed to the fully opened scissors body 2U and 2L. In the present embodiment, the heights of the outer walls 8U and 8L are lower in the vicinity of the front ends of the sandwiching portions 4U and 4L and in the ranges of the grip portions 5U and 5L than in other portions. However, the height of the outer walls 8U and 8L may be increased over the entire length of the scissors main bodies 2U and 2L.

  Convex portions 17U and 17L having gentle slopes are formed on the upper surface of the top plate 6 of the upper body 2U and the lower surface of the bottom plate 7 of the lower body 2L, respectively. In the present embodiment, the convex portion 17U of the upper main body is located slightly ahead of the convex portion 17L of the lower main body. With this shape, the position of the user's thumb and the index finger relative to the grip portions 5U and 5L are stabilized. As a result, the user can firmly hold the grip portions 5U and 5L.

  The aforementioned lock member 11 will be described with reference to FIGS. The cross section of the rear end of each grip part 5U, 5L is substantially U-shaped. An opening having a rectangular cross section is formed at the rear end of the connected grips 5U and 5L. The rear ends of the grip portions 5U and 5L are located slightly behind the support shaft 3. Therefore, the height of the opening is small when the scissors body 2U, 2L is opened (FIG. 6A), and the height of the opening is large when closed (FIGS. 6B and 6C). ). The height dimension of the opening when closed is substantially equal to the thickness of the rectangular parallelepiped insertion portion 18 of the lock member 11 described later. When closed, the upper and lower inner surfaces 26, 27 near the rear ends of the grip portions 5U, 5L, that is, the inner surface 26 (FIG. 4) of the top plate 6 and the inner surface 27 (FIG. 5) of the bottom plate 7 are substantially parallel. Become.

  The lock member 11 includes a rectangular parallelepiped insertion portion 18 that is inserted into the grip portions 5U and 5L from the opening, and a knob portion 19 that is formed continuously with the insertion portion 18. The insertion portion 18 is formed with a vertical slit 20 for mounting the torsion spring 10 described above. A long hole 21 is formed in the insertion portion 18. The aforementioned support shaft 3 penetrates into the long hole 21 and is attached to the scissors main bodies 2U and 2L. Since the lock member 11 is locked by the support shaft 3, it does not fall off. The long diameter of the long hole 21 substantially defines the advanceable / retreatable distance when the lock member 11 is operated. Up and down inclined surfaces (tapered surfaces) 23 that are close to each other toward the knob portion 19 are formed continuously from the upper and lower parallel surfaces 22 of the insertion portion 18.

  FIG. 6A shows a state in which the insertion portion 18 of the lock member is completely inserted into the grip portions 5U and 5L. In this state, the knob 19 reaches a position where it substantially contacts the rear ends of the grips 5U and 5L. This position is one of the operating positions F of the lock member 11. In this operation position F, the scissors main bodies 2U and 2L can be opened until the rear ends of the grip portions 5U and 5L are restricted by the inclined surface 23 of the lock member 11. When the scissors main bodies 2U and 2L are opened, the height dimension of the rear end opening is reduced. However, the thickness of the inclined surface 2 portion of the lock member 11 that comes into contact is also reduced. In the operating position F, of course, the scissors main bodies 2U and 2L can be closed (FIG. 6B). This is because the grip portions 5U and 5L are not restricted by the inclined surface 23 or the parallel surface 22 in the closing direction. FIG. 6B shows the same operating position F as FIG.

  FIG. 6C shows a state in which the insertion portion 18 is pulled out from the grip portions 5U and 5L until it is slightly exposed. In this state, the upper and lower inner surfaces near the rear ends of the grip portions 5U and 5L are in surface contact with the upper and lower parallel surfaces 22 of the insertion portion 18. This position is referred to as a lock position L of the lock member 11. At the lock position L, the scissors main bodies 2U and 2L are restrained in the closed state and cannot be opened. That is, since the rear ends of the grip portions 5U and 5L are restricted by the upper and lower parallel surfaces 22 of the insertion portion 18, the scissors main bodies 2U and 2L cannot be opened.

  Although not shown, the lock member 11 is an arbitrary position between the operation position F shown in FIGS. 6A and 6B and the lock position L shown in FIG. It can have a locking action. This intermediate position is also the operating position F. That is, by adjusting the position of the lock member 11, the lock member 11 can be locked at an arbitrary angle between the fully open angle (30 ° in the present embodiment) and the fully closed angle (0 ° in the present embodiment). Specifically, the knob 19 of the lock member 11 is pulled rearward in a state where the sandwiching portions 4U and 4L sandwich the fish. If it does so, scissors main body 2U and 2L will be controlled from the state which clamping part 4U and 4L clamped the fish. This is because when the lock member 11 is pulled rearward, the rear ends of the grip portions 5U and 5L abut against the inclined surface 23 of the lock member 11, and the scissors main bodies 2U and 2L cannot rotate in the opening direction. In this way, the fish scissors 1 can be locked at an opening corresponding to the size of the fish. In other words, the maximum opening of the scissors body 2U, 2L changes continuously according to the position of the lock member 11 between the position shown in FIG. 6A and the position shown in FIG.

  In the above embodiment, the scissors main bodies 2U and 2L are connected by the support shaft 3 in the vicinity of the rear end (near the rear ends of the grip portions 5U and 5L). However, it is not limited to such a configuration. For example, the scissors main bodies may intersect at an intermediate portion thereof, and the intersecting portion may be connected by a support shaft. In this case, the front of the coupling part of the scissors body is the clamping part, and the rear of the coupling part is the grip part. Even in this case, the width of the other scissors body is made smaller than the width of the one scissors body so that when closed, the other scissors body fits inside the outer wall of the one scissors body. Can be configured. In the case of such a structure, the lock member 11 is not employed.

  The fish scissors according to the present invention can be used for large and small fish, and is suitable not only for fishing but also for use in fresh fish stores.
