[0016] Figures 1 and 2 are plan and side views of the fork to which the present invention is applied, Figure 3 is a plan view of the fork with both opening and closing arms switched to the closed position, and Figure 4 is a block diagram showing a simplified configuration of the operating mechanism. The fork shown in these figures has a metal (specifically, aluminum) handle 1 formed in a straight line, and a bifurcated catch part 2 protruding further forward from one end (tip) of the handle 1.

[0017] The user uses the sashimata with the base end of the handle 1 facing forward and backward positioned closer to the user's body and the tip end of the handle 1 (the catch part 2) positioned farther from the user's body. The directions of forward and backward, left and right, and up and down are defined based on the user at this time. The following explanation will be given on this premise.

[0018] The handle 1 is formed in a cylindrical shape and has a hollow interior with a space (internal space) formed therein, and this internal space is open at the front (tip side).

[0019] A metal or synthetic resin handle 3 having a rectangular ring shape that is long in the front-to-rear direction in side view is integrally provided on the base end side, which is the rear end of the handle 1. The rear part of the handle 3, which is formed into a rod shape in the vertical direction, is the grip part 3a that is held by the user. A vertical gripping operation tool (operation tool) 4 is supported inside the ring shape of the handle 3 so as to be slidable in the front-to-rear direction, which is the longitudinal direction of the handle 3.

[0020] The gripping operation tool 4 is configured to be gripped together with the gripping portion 3a and pulled toward the gripping portion 3a (rearward). The gripping operation tool 4 is elastically biased toward the side (forward) away from the gripping portion 3a by a biasing member (not shown). In other words, when the operating force is released, the gripping operation tool 4 is displaced to a non-operating position away from the gripping portion 3a by the biasing force from the biasing member, whereas when gripped together with the gripping portion 3a, it is configured to be operated to an operating position close to the gripping portion 3a.

[0021] The capture portion 2 has a pair of left and right metal (specifically, alloy) frames 6, 6 which are integrally formed to protrude forward (further toward the tip) from the tip side of the handle 1 and have a symmetrical shape, and metal opening and closing arms 7, 7 attached to each of the left and right frames 6, 6 so that they can swing left and right.

[0022] The left and right frames 6, 6 protrude diagonally toward the sides (outside) where they are spaced apart from each other, forming a V-shape in plan view. Each frame 6 has a rigidity and strength that makes it difficult to deform, and the tip portion forms a guide portion 6a that is curved outward relative to the remaining portions.

[0023] The overall shape of the capture part 2 including the left and right frames 6, 6 is formed into a U-shape, a U-shape, or a Y-shape (Y-shape in this example) with an open front side. Due to this overall shape, the capture part 2 forms a capture space S with an open front side between the left and right frames 6, 6. This capture space S is a space for capturing the torso part of the subject. The guide parts 6a, 6a of the left and right frames 6, 6 act to guide the subject into the capture space S.

[0024] The left and right opening / closing arms 7, 7 are attached and supported at the midpoint of the frame 6, 6 on the closer side at their base ends, and are configured to swing left and right within a range limited between an open position in which they are swung to the outside of the frame 6 on the left and right, and a closed position in which they are swung to the inside of the frame 6 on the left and right (towards the capture space S).

[0025] In order to ensure such a swing range of the opening / closing arm 7, the fork must have a structure that passes through the frame 6 on the side closer to the opening / closing arm 7 in a plan view. Specifically, it is assumed that the opening / closing arm 7 is supported on either the upper or lower surface side of the frame 6, or a through hole 6b that passes through the frame 6 in the left-right direction is drilled in the frame 6 so that the opening / closing arm 7 that swings left and right can pass through. In the illustrated example, the latter structure is adopted.

[0026] In addition, the tip of the opening / closing arm 7 does not protrude beyond the tip of the frame 6 within its left and right swing range, and the passage hole 6b is formed in the shape of a closed elongated hole.

[0027] The left and right opening / closing arms 7, 7 have symmetrical shapes when switched to the open position and when switched to the closed position. The tip of each opening / closing arm 7 is curved or bent inwardly to the left and right with respect to the other parts, i.e., the middle part and the base part, to form a restricting part 7a.

[0028] When the left and right opening / closing arms 7, 7 are switched to a closed position, the left and right regulating portions 7a, 7a come close to each other and most of the open front portion of the capture space S is blocked (closed state), whereas when the left and right opening / closing arms 7, 7 are switched to an open position, most or all of them are positioned on the left and right outside of the left and right frames 6, 6 and the entire open front portion of the capture space S is opened (open state).

[0029] A biasing member is provided for elastically biasing the opening / closing arms 7, 7 in the switching direction to the closed position. In the illustrated example, this biasing member is provided for each of the left and right opening / closing arms 7, 7, but a single biasing member may be used to bias both the left and right opening / closing arms 7, 7 together in the switching direction to the closed position. Incidentally, a locking mechanism 9, 9 for engaging and locking the opening / closing arms 7, 7 in the open position is provided for each of the left and right opening / closing arms 7, 7.

[0030] The locking mechanism 9 is configured to switch between a locked state in which the corresponding opening / closing arm 7 is engaged and locked on the side where it can be switched to the open position, and a released state in which the locked state is released and the opening / closing arm 7 is allowed to swing toward the closed position.

[0031] A trigger operating device 11 is provided on the capture space S side (in other words, between the left and right frames 6, 6) which is operated by the subject captured within the capture space S, and a linkage mechanism 12 is provided which links the left and right swing (posture change) of the left and right opening and closing arms 7, 7 to the operation of this trigger operating device 11.

[0032] Trigger operating device 11 has an operated portion 13 formed in an arc shape concave toward the rear (base end side), and a shaft portion 14 that extends in a straight line from the middle of operated portion 13 to the rear and is coaxial with handle 1, forming a Y- or T-shape overall. Trigger operating device 11 is attached to and supported by handle 1 so as to be slidable in the axial direction by inserting shaft portion 14 into the internal space of handle 1 through an open portion at the front end of handle 1.

[0033] The trigger operating device 11 is configured to move and operate within a range between a state in which its operated portion 13 is pushed into the back of the capture space S and stored on the base end side of the left and right frames 6, 6 (operated state), and a state in which it advances to the open side of the capture space S (non-operated state). The fork is provided with a biasing member (not shown) that elastically biases the trigger operating device 11 to the non-operated state.

[0034] This trigger operating tool 11 is pushed (trigger operated) toward the switching side (specifically, backward) to the operating state against the biasing force of the biasing member by the torso side of the subject captured in the capture space S. The trigger fork is provided with an operating mechanism 16 that controls the swinging action of the left and right opening and closing arms 7, 7.

[0035] The operating mechanism 16 has the above-mentioned interlocking mechanism 12 which interlocks the swinging movement of the left and right opening / closing arms 7, 7 with the trigger operation of the trigger operating device 11, and a interlocking mechanism 18 which interlocks the pulling operation of the grip operating device 4 with the operation of the interlocking mechanism 12.

[0036] The interlocking mechanism 12 is configured to switch each of the pair of locking mechanisms 9 from a locked state to a released state when the trigger operating device 11 is operated. In this way, when each of the locking mechanisms 9, 9 is switched from a locked state to a released state, the corresponding opening / closing arm 7, 7 that has been locked in an open position by the locking mechanism 9, 9 is switched to a closed position by a resilient biasing force from a biasing member. In other words, the interlocking mechanism 12 is configured to switch each of the left and right opening / closing arms 7, 7 from an open position to a closed position when a single trigger operating device 11 is operated.

[0037] At least a part of the linking mechanism 18 (specifically, the metal core material 18a that can be pushed and pulled) is housed in the above-mentioned internal space. This linking mechanism 18 is configured to switch each of the left and right opening / closing arms 7, 7 from the closed position to the open position against the biasing force from the biasing member (i.e., swing them outward to the left and right) when the gripping operation tool 4 is gripped and operated from the non-operating position to the operating position.

[0038] Incidentally, the locking mechanisms 9, 9 provided for each of the left and right opening / closing arms 7, 7 are configured so that when the corresponding opening / closing arm 7, 7 is switched from the closed position to the open position, the locking mechanisms 9 are automatically switched from the released state to the locked state by contact with the opening / closing arm 7, 7. According to this configuration, when the opening / closing arm 7 biased to the closed position by a biasing member is switched from the closed position to the open position against the biasing force, the corresponding locking mechanism 9 is automatically switched to the locked state to hold the opening / closing arm 7 in the open position.

[0039] Next, the method of using the sashimata will be explained. When the user finds a suspicious person or an intruder, etc., with the left and right opening and closing arms 7, 7 locked in the open position, the user holds the gripping part 3a of the sashimata with one hand and holds the middle part of the handle 1 with the other hand, and thrusts the sashimata toward the target so that the target's torso is captured in the capture space S. This operation makes it difficult for the target to approach the user.

[0040] In addition, when a subject is captured within the capture space S, the subject operates the trigger operation device 11, which switches from the open state to the closed state, making it difficult for the subject to escape from the capture space S.

[0041] Furthermore, when the purpose of using the sashimata is accomplished, such as when handing it over to the police or when help arrives, the user grasps the gripping operation tool 4 together with the gripping portion 3a and switches it from the closed state to the open state, preparing for the next use.

[0042] In addition, the locking mechanism 9 may be omitted, and the single trigger operating device 11 and the left and right opening / closing arms 7, 7 may be mechanically linked by an interlocking mechanism 12 so that when the trigger operating device 11 is in an operated state, each of the left and right opening / closing arms 7, 7 is in a closed position, while when the trigger operating device 11 is in a non-operated state, each of the left and right opening / closing arms 7, 7 is in an open position.

[0043] Furthermore, although the linking mechanism 18 is mechanically connected directly to the opening / closing arms 7, 7, the linking mechanism 18 may be mechanically connected to the opening / closing arms 7, 7 via the interlocking mechanism 12.

[0044] Furthermore, the biasing member that biases the left and right opening / closing arms 7, 7 to the closed position can also be used as a biasing member that biases the gripping operation tool 4 to the non-operating position.

[0045] Next, with reference to Figs. 5 to 7, another embodiment of the present invention will be described, focusing on the differences from the above embodiment.

[0046] Fig. 5 is a plan view showing a state where the opening and closing arms of a stab device according to another embodiment of the present invention are switched to an open position, and Fig. 6 is a plan view showing a state where the opening and closing arms of the stab device shown in Fig. 5 are switched to a closed position. This stab device is provided with an electric shock device 20 that applies an electric shock to a subject. The electric shock device 20 has a pair of electrodes 7, 7, 19, 19, a power supply circuit 21 (see Fig. 7) that applies a high voltage between the pair of electrodes 7, 7, 19, 19, and change-over switches (change-over means) 22, 22 that switch between the application of this voltage and the absence of it.

[0047] Two pairs of electrodes 7, 7, 19, 19 are provided. The first pair of electrodes are the above-mentioned left and right opening and closing arms 7, 7. The second pair of electrodes are electrode arms 19, 19 attached and supported to the tip ends, which are the ends on the front side of the left and right frames 6, 6, respectively, so as to be swingable left and right.

[0048] The electrode arms 19, 19 have their base ends attached to and supported by the frames 6, 6, and are swung left and right about the supported base ends as a fulcrum. Each electrode arm 19 is configured to be switchable by this left and right swing between a closed position in which the tip end faces inward to the left and right, and an open position in which the tip end faces the user side (rear).

[0049] The swing of the electrode arms 19, 19 together with the opening / closing arms 7, 7 is controlled by the above-mentioned interlocking mechanism 12. Specifically, when each of the left and right opening / closing arms 7, 7 is switched to the open position, the interlocking mechanism 12 switches each of the left and right electrode arms 19, 19 to the closed position, whereas when each of the left and right opening / closing arms 7, 7 is switched to the closed position, the interlocking mechanism 12 switches each of the left and right electrode arms 19, 19 to the open position.

[0050] When each of the left and right electrode arms 19, 19 is switched to a closed position, it is switched to a closed state in which at least a portion (in this example, most of) of the open portion at the front of the capture space S is blocked, whereas when each of the left and right electrode arms 19, 19 is switched to an open position, it is switched to an open state in which the closed state of the electrode arms 19, 19 is released.

[0051] Incidentally, the left and right electrode arms 19, 19 are configured to be elastically changeable in the bending direction. Therefore, by pressing the electrode arms 19, 19 switched to the closed state against the subject and bending them, the subject can be captured in the capturing space S.

[0052] The changeover switches 22, 22 are disposed on the left and right ends of an operating rod 23 that extends in a straight line in a direction (left-right direction) intersecting (orthogonal to) the handle 1 in a plan view. Specifically, the operating rod 23 protrudes to both the left and right sides from the middle of the handle 1, and grips 24, 24 to be held by the user are formed integrally with the protruding left and right ends, respectively. The left and right changeover switches 22, 22 are momentary push buttons, and are provided so as to be operable by pressing at positions (specifically, on the back side of the portions of the operating rod 23 near the left and right ends) that can be operated by the thumb of the hand holding the grips 24, 24.

[0053] Fig. 7 is a block diagram showing the configuration of the electric shock device installed in the fork. The power supply circuit 21 is configured to switch between the application of a voltage between the pair of electrode arms 19, 19 and the application of a voltage between the pair of opening and closing arms 7, 7 based on the presence or absence of the pressing operation of the left and right change-over switches 22, 22.

[0054] Specifically, the power supply circuit 21 is configured to apply a voltage to at least one pair of electrodes 7, 7, 19, 19 of the two pairs of electrodes 7, 7, 19, 19 while one or both of the left and right change-over switches 22, 22 are pressed.

[0055] The subject receives an electric shock by touching a pair of electrodes 7, 7, 19, 19 to which a voltage is applied. That is, until the subject is captured in the capture space S, the electrode arms 19, 19 apply an electric shock to the subject, and once the subject is captured in the capture space S, the opening and closing arms 7, 7 apply an electric shock to the subject.

[0056] The thus constructed sarcophagus can be used with the electric shock device 20 to further improve the crime prevention effect.

[0057] In addition, the power supply circuit 21 may be configured so that when one of the left and right switches 22, 22 is pressed, a voltage is applied between one of the two sets of electrodes 7, 7, 19, 19, and when the other of the left and right switches 22, 22 is pressed, a voltage is applied between the other set of electrodes 7, 7, 19, 19, of the two sets of electrodes 7, 7, 19, 19.

[0058] Moreover, one of the two pairs of electrodes 7, 7, 19, 19 may be omitted. In particular, the configuration in which the electrode arms 19, 19 are omitted can be made to correspond to this configuration by adding a minimum amount of mechanical configuration to the above-mentioned configuration.

[0059] Furthermore, a structure may be adopted in which the opening / closing arms 7, 7 and the electrode arms 19, 19 can be operated separately. In this case, a dedicated operating tool for operating the electrode arms 19, 19 may be provided on the grips 24, 24 of the operating rod 23. [Explanation of symbols]
