Abstract
Description
[Technical field]
[0001] The present invention relates to a sasmata, a crime prevention device used to capture and subdue suspicious persons and criminals, and in particular to a sasmata having a claw to prevent it from falling out on the inner circumference of the capturing part formed by an arm that branches into two at the tip of the handle. [Background technology]
[0002] Sasmata is a crime prevention device used to capture parts of a criminal's body to immobilize them. It has a long handle with a forked arm at the end that is shaped like a U or V, which gives it the advantage that even if the captured person is holding a weapon such as a knife, it can be used to subdue them from a distance that is out of reach of the attacker.
[0003] However, even if the torso or limbs of a criminal are captured using the Sasumata, if the captured body part slips out from the opening of the capture section, the user of the Sasumata may be subjected to a counterattack from the captured person. In particular, when a single person is trying to subdue a criminal or when the user is not accustomed to using the Sasumata, there is a problem that the user may fail to capture and be harmed.
[0004] In response to this problem, Utility Model Registration No. 3127958 proposes a sasmata in which opposing claws are arranged on the inner circumference of the bifurcated arms of the capturing section, and when a part of the body of a person to be captured is introduced into this inner circumference, the arranged claws fall to the back of the inner circumference and are stored inside the arms, and when the capturing position is reached the claws return to their original position to close the opening, making it difficult for a body part that has been captured to slip out of the opening of the capturing section.
[0005] However, if the inner diameter of the gripping part is designed to fit the thickness of the torso or thighs of the person being captured, when the arm or ankle of the person being captured is captured by the gripping part, it has the drawback that it will quickly come off and the captured state will be released because it is much thinner than the inner diameter. Also, with a typical U-shaped or V-shaped gripping part, it is difficult to stop the movement of a criminal or the like who moves in a direction away from the user of the sasmata, such as escaping or moving toward another person.
[0006] Furthermore, even if a criminal is caught by a Sasumata, if the captured person is stronger than the Sasumata user, the captured person may release the restraint by force while grasping the gripping part or handle. In response to this, JP 2008-266657 A provides multiple pointed protrusions or ribs on the tip of the handle or on the surface of the arm, making it difficult for the captured person to grasp these parts and release the restraint.
[0007] However, for a user of a Sasumata who grasps the base end of the long handle, it is difficult to transmit force sufficiently to the grasping part at the tip when grasping the base end of the thin handle, so even if the captured person feels pain from the protrusions or ribs when grasping the tip of the handle or the grasping part, it is possible that they will not be able to adequately withstand the force exerted on them to release the captured state.

[0008] [Patent Document 1] Utility Model Registration No. 3127958 [Patent Document 2] JP 2008-266657 A Summary of the Invention [Problem to be solved by the invention]
[0009] The present invention seeks to solve the above-mentioned problems, and has as its objective the provision of a security device, sasmata, that enables even an amateur user to safely and reliably capture and subdue a person to be restrained. [Means for solving the problem]
[0010] Therefore, the present invention provides a sasmata that has a capturing section with two arms formed into a U-shape or V-shape at the tip of the handle, and captures the captured person by introducing a part of the body of the person to be captured from the opening side of the capturing section into the inner circumference while gripping the handle and holding it down. At predetermined positions on both arms on the inner circumference of the capturing section, a pair of claws are erected with their tips facing each other, and the base ends of the claws are axially attached to the arms in a state where the tips can be elastically tilted toward the bottom of the inner circumference, thereby forming a means for preventing the introduced body part from falling out. There are, The present invention is characterized by the above.
[0011] In this way, a pair of claws are provided opposite each other on the inner side of the capturing section formed by a bifurcated arm, with the tip side facing the bottom of the inner circumference and capable of being elastically tilted.When a part of the body of a captured person is introduced into the inner circumference from the opening side of the capturing section, the claws collapse to make it easy to introduce the part, but after introduction, the claws elastically return to their original position, forming an anti-detachment means that makes it difficult for the part to fall off.
[0012] Furthermore, in this Sasumata, the pair of claws are arranged in pairs at two locations, one at the longitudinal tip of each arm and one at the middle position, to form a two-stage anti-slip means.If the part of the body of the person to be captured is thick, the outer claw will prevent it from falling out, and if it is thin, the inner claw will prevent it from falling out, making it possible to achieve a reliable capture state depending on the thickness of the part to be captured.
[0013] Furthermore, in the above-mentioned sasmata, a plate is provided at the inner periphery of the capture portion so as to protrude toward the opening side at a predetermined height at the center position of the bottom side. The center is high and the left and right sides are slopingA convex portion formed in a mountain shape is provided, and the bottom side of the convex portion is central part If this is characterized in that a space is formed on each of the left and right sides by an arc-shaped concave edge line, then by introducing a thin part of the person to be captured, such as the wrist or ankle, into the bottom side of the inner circumference of the capturing part and twisting the handle to rotate the capturing part, it becomes easy to firmly capture the part on one side of the space divided by the convex part in the center of the bottom.
[0014] Furthermore, if the hook portion of the above-mentioned sasmata is characterized in that the sickle-shaped part is pivoted at its base end to the tip of the arm with the tip end able to be elastically tilted toward the base end of the capturing part, then when attempting to introduce part of the body of the person to be captured into the inner circumference of the capturing part, or when attempting to insert the capturing part behind the person to hook it with the hook portion, the sickle-shaped part will elastically tilt to reduce the left and right width of the tip of the sasmata, making it less likely to interfere with the above-mentioned movements.
[0015] In addition, if the above-mentioned Sasumata is characterized in that a plurality of sharp metal protrusions are arranged at specific positions on the surface of the capturing portion and at specific positions on the outer circumferential surface of the tip side of the handle, it becomes difficult for the captured person to grasp those parts, making it easier to prevent the restraint state from being released.
[0016] In addition, in the above-mentioned sasmata, if a rod-shaped handle member of a predetermined length is connected to a predetermined position on the base end of the handle in a state in which the base end is freely attached and detached perpendicular to the longitudinal direction of the handle, and it can be used as a baton by removing it from the handle, then by connecting the handle member to the base end of the handle at right angles, even a user with little strength can easily apply force to the grasping part, and if the handle member is removed from the handle and used as a baton, it can be used to knock down a weapon held by a captured person. Effect of the Invention
[0017] In addition to providing opposing claws on the inner circumference of the capturing portion in a tiltable state, the present invention provides a sickle-shaped hook portion on the tip of the arm, making it easy for even an amateur user to safely and reliably capture and subdue the person to be restrained. [Brief description of the drawings]

[Diagram 2] FIG. 2 is an enlarged partial view for explaining the configuration and function of the capture part of the Sasumata in FIG. 1, in which (A) shows the state before a part of the body of the person to be captured is introduced into the capture part, and (B) shows the state after introduction is completed and the person is captured. [Diagram 3] This is an enlarged partial view to explain the function of the capture part of the Sasumata in Figure 1, where (A) shows the state in which part of the body of the captured person has been introduced to the bottom of the capture part, and (B) shows the state in which the capture part has been twisted after introduction to achieve a completely captured state. [Figure 4] 1A is a side view of a modified example of the sasmata of FIG. 1, and FIG. [Diagram 5] FIG. 2 is a side view of an application example of the sasmata of FIG. 1. [Figure 6] FIG. 6 is an enlarged partial view for explaining the configuration and function of the base end side of the susmata in FIG. 5. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0020] Fig. 1 shows a sasmata 1A according to the present embodiment, with Fig. 1(A) being a side view and Fig. 1(B) being a plan view. This sasmata 1A is a metal crime prevention tool for capturing and subduing suspicious persons and criminals, and is provided with a capture part 2A, which is made of two horseshoe-shaped metal plates stacked together so that two arms 20, 21 are formed into a U-shaped fork, at the tip side of a handle 3A, which is provided with a grip 31 at the base end side of a metal tube 30. The user grasps the handle 2A and introduces a part of the body of the person to be captured from the opening side of the capture part 2A into the inner periphery and holds it down to capture the person.
[0021] In addition, in this sasmata 1A, a pair of claws 23, 23 and claws 24, 24 are respectively erected at the longitudinal tip and middle positions of both arms 20, 21 on the inner periphery of the capturing section 2A, with their tips facing each other, and their base ends are sandwiched between the metal plates and axially attached in a state in which they can be stored between the two metal plates that make up the arms 20, 21 while the tip sides are elastically tilted toward the bottom side of the inner periphery, forming a two-stage anti-detachment means for the part of the body of the captured person that has been introduced.
[0022] That is, as shown in FIG. 2(A), by pressing the opening side of the capturing portion 2A of the susmata 1A against the thigh 100 of the person to be captured (near the knee joint), the claws 23, 23, 24, 24 pressed against the sides fall down and the thigh 100 is completely introduced into the inside part of the capturing portion 2A, but when the thigh 100 passes the position of the claws 23, 23, as shown in FIG. 2(B), the elastic repulsive force of the springs 210, 210 arranged on the base end side shown by the dashed line returns the claws 23, 23 to their original positions, and a stopper (not shown) prevents the tip side from opening any further.
[0023] Therefore, the pair of outer claws 23, 23 function as a slip-out prevention means for preventing the thigh portion 100 from slipping out from the opening side of the capturing portion 2A, and since this makes it easier to maintain the captured state of the person once subdued, even if the user of the Sasumata 1A is an amateur or a weak person, he or she can easily capture and subdue the target person safely and reliably.
[0024] 3 shows the state in which the arm 110 of the person to be captured is captured by the sasmata 1A, but since the arm 110 is much thinner than the thigh 100 described above, it is captured in the inner space of the anti-detachment means formed by the pair of claws 24, 24 located on the innermost side of the capturing part 2A. In this case, if the arm 110 is as thin as a wrist, a gap is created between the arm 110 and the inner periphery (edge portion) of the arms 20, 21, making it relatively easy to pull it out in the thickness direction of the arms 20, 21.
[0025] Therefore, as shown in FIG. 3(B), by holding the grip 31 side (not shown) of the sasmata 1A and twisting it to rotate the capturing portion 2A around the central axis, the gap that has formed between the inner sides of the arms 20, 21 can be reduced or eliminated, making it difficult to pull out the arm portion 110 and making it easier to maintain the captured state.
[0026] In this case, the inner circumference of the capturing part 2A of this embodiment is provided with a convex part 25 formed by forming a plate material into a mountain shape so as to protrude toward the opening side at a predetermined height at the center of the bottom side, and since spaces are formed on both sides of the mountain shape on the bottom side by the edge lines concave in an arc shape, by introducing a thin part of the body such as a wrist into the inner bottom side of the capturing part 2A and rotating it, the center of the bottom can be firmly captured on one side of the space divided by the convex part 25. The same applies if the body part to be captured is the ankle, and if the tip of the convex part 25 (the apex of the mountain shape) is made sharp, it is possible to inflict pain on the captured person by pressing the capturing part 2A against him, making it easier to subdue him.
[0027] In addition to the function of the two-stage removal prevention means using the claws 23, 23, 24, 24 described above, the sasmata 1A of this embodiment also has an important characteristic in that the tip of one of the arms 20, 21, arm 21, is provided with a hook portion 27 consisting of a sickle-shaped part extended in the centrifugal direction (side) of the extension line of the central axis of the handle 3A.
[0028] In this way, by providing a sickle-shaped hook portion 27 extending centrifugal from the extension of the central axis of the handle 3A at the tip side of the arm 21, this can be used to hook the foot of the captured person to cause him to fall, or to hook it around a part of the body to prevent him from moving away from the user of the Sasumata 1A, thereby further improving the crime prevention performance.
[0029] Fig. 4 shows a sasmata 1B as a modified example of the sasmata 1A in Fig. 1. This sasmata 1B has projections 210, 220, 230, 240 (not shown) on the left and right surfaces of the capturing part 2B, each of which is made up of a plurality of triangular metal projections with pointed tips, and projections 250, 260, 270 on the outer peripheral surface of the tip side of the metal tube 32 of the handle 3B, each of which is made up of a plurality of triangular metal projections arranged in a circumferential direction. This makes it difficult for the captured person to resist while holding onto that part, making it easier for even a weak user to subdue the captured person.
[0030] Figures 5 and 6 show a sasmata 1C as an application example of the sasmata 1A in Figure 1. In this sasmata 1C, the hook part 28 is characterized in that the tip side of the sickle-shaped part constituting it is elastically tiltable toward the base end side of the capture part 2C, and the base end side of the hook part 28 is pivotally attached to the tip side of the arm 22.
[0031] As a result, when introducing a part of the subject's body into the inner circumference of the capturing part 2C or when the capturing part 2C is inserted behind the subject and hooked by the hook part 28, the sickle-shaped part can be elastically tilted toward the base end by a spring or the like, thereby reducing the width and making it difficult to interfere with the above-mentioned movement. Note that a stopper (not shown) is also provided on the base end of the hook part 28 so that it does not open further than the angle position shown by the solid line in FIG. 5.
[0032] Another feature of this sasmata 1C is that a rod-shaped handle member 36 is detachably connected at its base end to the boundary between the grip 25 on the base end side of the handle 2C and the exposed part of the metal tube 20. This handle member 36 is firmly connected to a connecting part 352 disposed on the tip side of the grip 35, so that even a user with little strength can easily apply force to the grasping part 2C, and in particular, it makes it easy to twist the grasping part as shown in Figure 3(B).
[0033] 6, the handle member 36 can be easily removed by simply pressing the release button 352a located on the surface of the connection part 352, and the removed handle member 36 can also be used as a baton. For example, if a captured person is holding a weapon such as a kitchen knife, it can be used to knock the weapon away by holding the base end of the handle member 36 and hitting the ball part 36b on the tip side.
[0034] It is also possible to extend the length of the handle 3C by connecting the removed handle member 36 to the connection part 251 provided at the base end of the grip 35. The handle member 36 can be attached by simply inserting the connection fitting 36a on the base end side into the connection parts 351, 352, and can be removed by simply pressing the release buttons 351a, 352a, but a screw-in type may be used instead.
[0035] Furthermore, this application example can also be applied to the above-mentioned sasmata 1B in Fig. 4. In addition, in all of the above-mentioned embodiments, modifications, and application examples, the case where the catching part provided on the tip side of the handle is U-shaped has been described, but it goes without saying that it may be V-shaped.
[0036] As described above, the present invention has made it possible for the security tool Sasumata to be used by an amateur user to easily capture and subdue a person to be restrained safely and reliably. [Explanation of symbols]
