Description

[Technical Field]

[0001] This invention relates to a fork. [Background technology]

[0002] A sashimata (sarimata) is a restraining device with a U-shaped or forked arm structure at the end of a long handle, and is mainly used in crime prevention and security situations. The user can use the arms to restrict or restrain the target while maintaining distance from them.

[0003] The user firmly supports the sarmata, holds the arms toward the torso, shoulders, and chest of the target, and while maintaining a distance from the target, approaches from the side or front to leave no room for retreat or escape, trapping the target's torso inside the arms of the sarmata and greatly restricting the target's movement. Furthermore, while still restrained by the arms, if the entire sarmata is pushed forward and pressed against a wall or the ground, the target trapped between the wall or ground will find it difficult to move, and the subjugation state will become more stable.

[0004] Historically, the tsubaki has been used as a tool for catching criminals, and in modern times it is kept on hand in schools, public facilities, police stations, etc. to deal with suspicious individuals. Its purpose is to safely apprehend the target without causing injury, and modern improvements have been made to it by making it lighter and adding functions.

[0005] In this regard, Patent Document 1 describes a forked arrest device that has two handles 1, 1' long enough to maintain a sufficient distance from the arrestee and supported rotatably by a pivot 2 in a scissors-like manner, with catch sections 3, 3' for grasping the arrestee formed at one end and grip sections 4, 4' formed at the other end, and a fixing device 5 provided near the grip sections 4, 4' to prevent the handles from opening.

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-250452 Summary of the Invention [Problem to be solved by the invention]

[0007] In the case of the invention described in Patent Document 1 above, the user holds the left handle with their right hand and the right handle with their right hand, and when they perform the closing operation while both handles are open to the left and right, the arms close. Therefore, it may be difficult for the user to smoothly perform the series of actions required to capture a target: the approach action (stepping forward with force) and the action of forcefully closing the left and right handles with both hands (pulling back with force).

[0008] The present invention was proposed in consideration of the above points, and aims to provide a fork that can firmly capture a target and improve restraining power. [Means for solving the problem]

[0009] In order to solve the above problems, the needle of the present invention comprises an arc-shaped first arm portion, an arc-shaped second arm portion, a first handle portion connected to the first arm portion, a second handle portion connected to the second arm portion, and a pivot portion that rotatably supports the first handle portion and the second handle portion in a scissors-like manner, and is configured so that when the first handle portion and the second handle portion are rotated in an opening direction around the pivot portion as an axis, the tips of the first arm portion and the second arm portion move closer to each other. [Effects of the Invention]

[0010] According to the embodiment of the present invention, it is possible to provide a fork that can firmly capture a target and improve restraining power. [Brief explanation of the drawings]

[Figure 2] FIG. 1 is a front view showing a fork (arms closed) according to the present embodiment. [Figure 3] 2A and 2B are a plan view and a front view showing the tip portions of the left arm and the right arm according to the present embodiment. [Figure 4] 10A and 10B are a plan view and a front view showing a hooked state of the arms according to the present embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0012] The present invention will be described in detail with reference to the drawings. When the same reference numerals are used in multiple drawings, the description will be omitted.

[0013] FIG. 1 is a front view and a right side view of a fork (arms open) according to this embodiment. FIG. 2 is a front view of a fork (arms closed) according to this embodiment. Fork 1 according to this embodiment is composed of a handle 2 consisting of a left handle 2a and a right handle 2b, a screw 3, a pull-out hole 4, a wire locking portion 5, an arm 6 consisting of a left arm 6a and a right arm 6b, a wire hook 8, and a wire (loop wire) 9. Fork 1 according to this embodiment has a structure in which handle 2 and arm 6 are integrally connected so that when handle 2 is closed, arm 6 opens (FIG. 1), and when handle 2 is opened to the left and right, arm 6 closes (FIG. 2).

[0014] The handle (grip) 2 is the part where the user operates the fork by holding the left handle 2a with the left hand and the right handle 2b with the right hand, and is part of the mechanical fulcrum that transmits force to the opening and closing movement of the arm 6 connected to it.

[0015] The screw 3 is a central axis part (pivot) that fixes the two handles 2 and the arm 6 as a fulcrum at one point, while enabling the rotational movement of opening and closing. The force applied from the force point at one end of the handle 2 is transmitted to the arm 6 (point of application) with the screw 3 at the center.

[0016] The pull-out hole 4 is provided in the right handle 2b and is an opening (hole) for pulling out the wire 9. In the fork fork 1 according to this embodiment, the wire 9 passes through the inside of the right handle 2b and the right arm 6b, and the other end of the wire 9 is pulled out from the pull-out hole 4 of the right handle 2b.

[0017] The wire locking portion 5 is a wire locking portion for locking a loose wire 9 in order to lock the arm 6 in the closed state when the arm 6 is closed. Specifically, the user winds the wire 9, which is pulled out from the pull-out hole 4 of the right handle 2b, around the wire locking portion 5.

[0018] Arm 6 is the tip of a fork for enclosing a subject and restricting or restraining their movement, and is an arc-shaped structure that opens and closes when a force is transmitted as a point of application operated by the user. As described above, when the user opens handle 2 to the left or right, the tips of left arm 6a and right arm 6b move toward each other in the closing direction, and arm 6 is closed.

[0019] As described above, the fork 1 according to this embodiment is structured so that when the user opens the handle 2 to the left and right, the tips of the left arm 6a and the right arm 6b move toward each other in the closing direction, closing the arms 6. When capturing a target, the user firmly grasps the left handle 2a with their left hand and the right handle 2b with their right hand (the left and right handles 2a and 2b may be slightly more open than in the state shown in Figure 1 , allowing the user to easily grasp them), holds the arms 6 toward the torso, shoulders, and chest of the target, and faces the target at a certain distance. The user approaches the target, traps the target inside the arms 6, and forcefully opens the left and right handles 2a and 2b with both hands. The user's approaching action (stepping forward) and forcefully opening the left and right handles 2a and 2b with both hands (pushing forward) are a smooth and intuitive series of actions and manipulations required for capturing a target.

[0020] Fig. 3 is a plan view and a front view showing the tip of the left arm and the right arm according to this embodiment. Fig. 4 is a plan view and a front view showing the hooked state of the arms according to this embodiment. A wire hook 8 is provided at the tip of the left arm 6a according to this embodiment, and a wire loop 9T is provided at the tip of the right arm 6b, where one end of a wire 9 is pulled out from inside the right arm 6b and processed into a loop shape (closed loop).

[0021] When the user opens the handle 2 to the left or right, the left arm 6a and the right arm 6b move in the closing direction, and eventually the wire loop 9T at the tip of the right arm 6b hooks onto the wire hook 8 at the tip of the left arm 6a. To ensure reliable hooking, the user should open and close the handle 2 to the left or right several times after the left arm 6a and the right arm 6b come into contact.

[0022] Furthermore, after the wire loop 9T is hooked to the wire hook 8, the user pulls out the wire 9 that has been pulled out from the pull-out hole 4 of the right handle 2b as far as possible, and then winds the wire 9 around the wire locking portion 5 to lock and secure the wire 9. This makes it extremely difficult for the wire loop 9T to come off the wire hook 8. Furthermore, for example, if a subject who has been trapped inside the arm tries to open the arm 6, even a weak user can easily maintain the arm 6 in its closed state, making it more difficult for the subject to escape.

[0023] It is possible to use aluminum or stainless steel as the material for the handle 2 and arm 6 of the sagami 1, but if the arm 6 is made of a flexible material such as carbon fiber, the user can pull the wire 9 from the hand of the right handle 2b as far as possible, causing the arm 6 to bend, tightly clamping and capturing the target trapped inside the arm 6. The clamping force can also be adjusted.

[0024] As described above, the fork 1 according to this embodiment allows the user to securely capture a target by opening the handle, and the addition of a wire-pulling mechanism further enhances the restraining force. While the present invention has been described using specific examples in accordance with preferred embodiments, it is clear that various modifications and variations can be made to these examples without departing from the broad spirit and scope of the present invention as defined by the claims. In other words, the details of the examples and the accompanying drawings should not be construed as limiting the scope of the present invention. For example, the sizes of the fork 1 shown in Figure 1 are merely examples. Any size appropriate for a fork may be used, and the handle 2, for example, may be extendable.
