  Hereinafter, the present invention will be described based on embodiments. First, the shelling device 10 according to the first embodiment of the present invention will be described with reference to FIGS.

  The shelling device 10 is directed to peeling shellfish shells. In the following description, the shelling device 10 will be described as being used for shelling the pedestal legs (legs other than scissors legs) of the crab legs.

  The shelling device 10 generally has a configuration similar to a so-called tong, which is a tool for pinching or grasping an object. The shelling device 10 includes a sandwiching portion 12 and a blade portion 14.

  The pinching portion 12 is configured to be able to pinch a crab's limb, that is, its shell. The sandwiching portion 12 includes a first sandwiching piece portion 18 that extends in the longitudinal direction and a second sandwiching piece portion 20 that also extends in the longitudinal direction. The first and second sandwiching piece portions 18 and 20 are connected on the proximal end side in the longitudinal direction. In particular, the first and second sandwiching piece portions 18 and 20 are connected at an end portion (base end portion) on the base end side.

  The base end portion of the shelling device 10 is configured as a connecting portion 22 that connects the first and second clip pieces 18 and 20. The connecting portion 22 includes a C-shaped portion 22 a having a substantially C-shaped cross section, and connecting ends 22 b and 22 c provided between the C-shaped portion and the first and second sandwiching piece portions 18 and 20. The connecting portion 22 is configured to expand the first and second sandwiching piece portions 18 and 20 on the distal end side in a state where no external force is received. That is, the shelling device 10 is in the open state of FIGS. 1 and 2 in a state where it does not receive external force. By applying an external force (for example, the force of a human hand) so as to close the first and second clip pieces 18, 20, at least a part of the connecting portion 22 is elastically deformed, and thus the first and second clip pieces On the tip side of 18, 20, their spacing can be reduced. As described above, the shelling device 10 is configured such that the distance between the first and second sandwiching piece portions 18 and 20 is variably set, particularly on the tip side thereof. The movement of the first and second sandwiching piece portions 18 and 20 with respect to each other is made possible by elastic deformation of the connecting portion. In the shelling device of the present embodiment, the connecting portion 22 corresponds to an elastic portion.

  The first clip piece 18 has a substantially arcuate cross section that protrudes outward at an arbitrary position in the longitudinal direction. Therefore, the inner surface (first inner surface) 24 of the first sandwich piece 18 is concave. The first inner surface 24 extends in the longitudinal direction and has substantially the same cross section in the longitudinal direction. Similarly, the 2nd pinching piece part 20 has the substantially arc-shaped cross section which protrudes outside in the arbitrary locations of the longitudinal direction. Therefore, the inner surface (second inner surface) 26 of the second sandwich piece 20 is also concave, extends in the longitudinal direction, and has substantially the same cross section in the longitudinal direction.

  A blade portion 14 is provided in the sandwiching portion 12 configured as described above. Here, the blade portion 14 has two tooth portions 30 and 32. The first tooth portion 30 is provided on the first inner surface 24 of the first clip piece portion 18, and the second tooth portion 32 is provided on the second inner surface 26 of the second clip piece portion 20. As shown in FIGS. 2 (b) and 3 (b), each of the tooth portions 30 and 32 is thin in the lateral direction or the width direction (which is a direction orthogonal to the longitudinal direction), while extending in the longitudinal direction. It is configured. Here, each tooth part is comprised so that it may have a substantially triangular shape in FIG.2 (c), (f). Therefore, the 1st tooth part 30 protrudes toward the 2nd pinch piece part 20, the tooth crest part 30a in the most protruding position, the tooth tip part 30b of the tip side rather than the tooth crest part 30a, and the tooth crest part 30a It has a tooth base end portion 30c on the base end side. In the first tooth portion 30, a cutting edge 30d is formed along the ridge line portion from the tooth tip portion 30b to the tooth base end portion 30c via the tooth crest portion 30a. Similarly, the second tooth portion 32 protrudes toward the first pinching piece portion 18 and has a tooth crest portion 32a, a tooth tip portion 32b, and a tooth base end portion 32c, and extends along the ridge line portions thereof. It has an existing cutting edge 32d. It should be noted that the sharpness of the cutting edges 30d and 32d should be determined to such an extent that when the shelling device 10 is used, the tooth portion can be pierced into the shell and torn in the longitudinal direction by a moderate force of a human hand. .

  The blade portion 14 is arranged at the most distal end (tip portion) 12D of the sandwiching portion 12 in the longitudinal direction, particularly on the inner surfaces 24 and 26 thereof. As a result, as will be described later, it is possible to split the shell with the tooth portions 30 and 32 until the end.

  Further, when the blade portion 14 is in a closed state in which the first sandwiching piece portion 18 and the second sandwiching piece portion 20 are in contact with each other on the distal end side in the longitudinal direction, as shown in FIG. Is configured to be substantially opposite to the second tooth portion 32 and located away from the second tooth portion. Thereby, the collision with the 1st tooth part 30 and the 2nd tooth part 32 can be prevented, and these tooth parts can be maintained in a more suitable state. However, the interval between the first tooth portion 30 and the second tooth portion 32 in the closed state may be arbitrarily determined according to the size of the target shell. More precisely, the first tooth portion 30 and the second tooth portion 32 are at substantially the same position in the longitudinal direction and at substantially the same position in the lateral direction. However, the 1st tooth part 30 and the 2nd tooth part 32 may exist in the position shifted in the longitudinal direction, and may exist in the position shifted in the transversal direction.

  The shell peeling with the shell peeling device 10 having the above-described configuration, that is, its use state will be described with reference to FIG. In FIG. 4, the shelling device 10 is used for shelling the crab limb CL.

  First, as shown in FIG. 4A, the pedestrian CL is placed in a space S partially defined by the first inner surface 24 of the first clip piece 18 and the second inner surface 26 of the second clip piece 20. Position it. By applying a force to the shelling device 10 in this state so that the pinching portion 12 is closed at the tip end side, the shell of the pedestal CL can be pinched by the pinching portion 12, thereby the first pinching piece portion 18. The first tooth portion 30 and the second tooth portion 32 of the second clip piece portion 20 are in contact with the shell of the walking leg CL. Then, when further force is applied, the state shown in FIGS. 4B and 4C is obtained, and the first tooth portion 30 and the second tooth portion 32 pierce the shell of the pedestrian CL, respectively. In this state, as shown by the arrow in FIG. 4 (b), the shelling device 10 is substantially longitudinal with respect to the pedestal CL, and further along the shape of the pedestal CL as shown by the arrow in FIG. 4 (a). By relatively moving, the shell of the pedestal CL can be cut into two as shown in FIG.

  Thus, according to the shelling instrument 10, the crab pedestal shell can be split in the longitudinal direction without bending the crab pedestal. Therefore, by using the shell peeling device 10, the shell can be suitably peeled off and the body can be taken out cleanly.

  Moreover, since the blade part 14 is located at the front-end | tip part of the clamping part 12, when a shell is torn, according to the shape of a shell, the space | interval between the tooth parts of the blade part 14 can be changed flexibly also at the edge part. (See arrow in FIG. 4 (a)). Therefore, until the end, the shell of the pedestrian CL can be cut with the blade portion 14.

  Further, as described above, the first inner surface 24 of the first clip piece 18 and the second inner surface 26 of the second clip piece 20 are configured as concave inner surfaces extending in substantially the same shape in the longitudinal direction. ing. Therefore, when the shelling device 10 is moved so as to cut the shell, the holding ability or shape following property of the shelling device 10 to the shell is high. In addition, since the concave shape of the first inner surface 24 and the second inner surface 26 is determined to have an arc-shaped cross section, the shelling device 10 is widely applicable to various shapes and sizes of crab leg shells. can do.

  Next, a shell peeling instrument 110 according to a second embodiment of the present invention will be described with reference to FIG. In the following, the main difference between the shelling device 110 and the shelling device 10 of the first embodiment described above will be described.

  In the shelling device 10 of the first embodiment, the two clip pieces 18 and 20 are manufactured from the same material in series with the connecting portion 22. However, in the shelling device 110 of the second embodiment, two tooth portions 130 and 132 of the blade portion 114 (configured to be arranged at the tip portion of the sandwiching portion 112 as in the blade portion 14) are provided. The clip pieces 118 and 120 are manufactured separately from each other. And these clip piece parts 118 and 120 are connected and connected by a connecting member (connecting part) 122 provided so as to extend in the lateral direction. Therefore, the sandwiching piece portions 118 and 120 can be opened or closed on the distal end side with the connecting member 122 as the center.

  In the shelling device 110 of the second embodiment, the elastic member 123 is held at the proximal end portion of the sandwiching piece portions 118 and 120 so that the distal end portion of the sandwiching portion 112 is maintained in an open state without receiving external force. Is provided. The elastic member 123 is provided inside the sandwiching piece portions 118 and 120, but may be provided outside. The elastic member 123 can be a leaf spring or the like.

  As mentioned above, although this invention was demonstrated based on the said embodiment, this invention is not limited to those embodiment. For example, the blade portion is not limited to being positioned at the most distal end portion of the sandwiching portion, and can be provided at an arbitrary position shifted from the distal end portion of the sandwiching portion to the proximal end side. However, preferably, the blade portion is positioned at the tip of the sandwiching portion. Moreover, the number of the tooth | gear part in a blade part is not limited to two, One may be sufficient, and three or more may be sufficient. Therefore, the number of teeth provided in each of the two clip pieces is not limited to being the same, and may be different. Moreover, each tooth part is not limited to having a cutting edge over the whole ridgeline part, You may have a cutting edge only in the part. Preferably, at least a cutting edge may be formed from the top part of the tooth part to the base end part. Note that the tooth portion is not limited to a substantially triangular shape as described above, and can have various shapes that can be pierced into the shell and torn during use.

  In the above description, the shelling devices 10 and 110 have been described as being used for shelling the crab limbs. However, the shelling devices 10, 110 may be used to shell crab scissors legs and shrimp tails.

  As mentioned above, although typical embodiment of this invention and its modification were demonstrated, this invention is not limited to them, A various change is possible. Various substitutions and modifications may be made without departing from the spirit and scope of the invention as defined by the claims of this application.
