Description

[Technical Field]

[0001] The present invention relates to security devices, and more particularly to control shields, control rods and combinations thereof used for self-defense against attacks from attackers such as thugs and intruders, and for controlling and repelling such attackers. [Background technology]

[0002] Police and security companies use crime prevention equipment such as shields, batons, and batons to fight against violent attackers such as thugs and intruders. Recently, there has also been an increasing demand for crime prevention equipment to fight against violent attackers in educational institutions, financial institutions, and general stores. A shield is basically used by an interceptor to defend against an attack by an attacker, a baton is basically used by an interceptor to intimidate or counterattack an attacker to control or repel the attacker, and a sarmature is basically used by an interceptor to stop the movement of the attacker to control or restrain the attacker. For example, there are Patent Documents 1 and 2 regarding shields, Patent Documents 3 and 4 regarding batons, and Patent Documents 5 and 6 regarding sarmatures. It is difficult for security equipment to achieve sufficient subjugation against an attacker by relying solely on one of its capabilities, which differ from the perspectives of defense, intimidation, attack, control, and restraint. To compensate for the weaknesses of individual security equipment, an interceptor can, for example, use a shield and a baton simultaneously, combining the defensive power of the shield with the intimidating and offensive power of the baton to increase subjugation. As in this example, security equipment is required to achieve high subjugation against an attacker by comprehensively utilizing the capabilities from the different perspectives described above. In addition, because attackers will launch various attack patterns against interceptors, changing the type and timing of their attacks, the interceptor must be able to switch between defense and counterattack flexibly according to the attacker's movements and quickly restrain the attacker when the opportunity arises. Therefore, crime prevention equipment is required to enable the interceptor to quickly switch between the most appropriate defense, counterattack, or restraining action according to the attacker's movements. Furthermore, security equipment must be convenient, such as easy to store under normal circumstances and quick to respond in emergencies. [Prior art documents] [Patent documents]

[0010] Figures 19A and 19B are photographs showing an example of a combination of an aluminum control shield of the present invention and an aluminum control rod of the present invention. Specifically, Figure 19A is a photograph showing the front of the control shield and the left side of the control rod, and Figure 19B is a photograph showing the back of the control shield and the right side of the control rod. Figures 20A and 20B are photographs showing an example of a combination of a resin control shield of the present invention and a resin control rod of the present invention. Specifically, Figure 20A is a photograph showing the front of the control shield and the left side of the control rod, and Figure 20B is a photograph showing the back of the control shield and the right side of the control rod. FIG. 21 is a photograph showing the basic posture in which an aluminum control shield of the present invention is held in the left hand and an aluminum control rod of the present invention is held in the right hand, facing an attacker. The control shield and control rod of the present invention have an appearance that can visually intimidate an attacker, and can be expected to have the effect of causing the attacker to lose their aggressive intention and retreat before the attack even begins. From the perspective of crime prevention tools, it is preferable because if the attacker is intimidated and retreats before the attack begins, the victim can escape the crisis unharmed. The control shield, control rod, and combinations thereof of the present invention will be described below. Note that in the present invention, the symbol "to" indicating a range of values ​​is used to mean that the values ​​before and after it are included as the lower and upper limits.

[0011] I. Control Shield The control shield of the present invention is a control shield having a shield body made of a plate-shaped material and a grip portion provided on the back surface of the shield body, The shield body has a vertically elongated shape when viewed from the front, At least a part of a first side portion arbitrarily selected from both sides of the shield body is provided with an impact protection section having a rib structure in which the edge of the first side portion is bent toward the back side of the shield body along a bending axis running in the vertical direction of the shield body, The shield is provided with a stab protection part having a continuous protrusion structure in which a plurality of mountain-shaped protrusions protruding laterally from the shield body are arranged along the edge of the second side, at least in a part of the second side facing the first side, of both side parts of the shield body; The shield is characterized by having a striking part at the top of the shield body, which has at least one tip formed in a mountain shape that protrudes above the shield body.

[0012] Figures 1 to 7 show an example of a control shield (control shield 101) of the present invention. Figure 1 is a six-sided view of the control shield 101, Figure 2 is a front view, Figure 3 is a rear view, Figure 4 is a top view, Figure 5 is a bottom view, Figure 6 is a right side view, and Figure 7 is a left side view. 8A to 8C show grip members attached to the rear surface of the control shield 101, specifically, FIG. 8A is a front view, FIG. 8B is a top or bottom view, and FIG. 8C is a right or left side view.

[0013] The control shield 101 has a grip portion 2 and a first various equipment attachment portion 3a on the back of the shield body 1 made of a plate-shaped material, and further has a second various equipment attachment portion 3b on the top surface of the grip portion. The plate-shaped material that forms the main body of the shield can be appropriately selected from materials that have the necessary strength, rigidity, hardness, durability, and other characteristics for the shield, as well as formability and workability that allows for bending, drilling, plastic processing, etc. For example, metal materials such as aluminum alloys and stainless steel, engineering plastics such as polycarbonate and Kydex (registered trademark) (a high-impact acrylic modified resin manufactured by Sekisui Seiki Kogyo Co., Ltd.), and resin materials such as composite resins with added fillers can be used. The shield body 1 of the illustrated control shield 101 has a vertically elongated shape when viewed from the front, with a length L (vertical dimension) of 607 mm and a width W (horizontal dimension) of 289 mm when viewed from the front, and a plate thickness T of 3 mm when viewed from the side. In the present invention, the dimensions of the shield body are such that when an adult human holds the shield in the hand and assumes a basic fighting stance, the upper body or head and chest are almost completely hidden when viewed from the front, and the length L is generally set to 560-660 mm, and the width W is set to 240-340 mm, taking into consideration the need to accommodate a wide range of sizes from small women to large men. There are no particular restrictions on the thickness T, but in consideration of sufficient defensive capability as a shield, material properties, and weight, it is generally set to 3-5 mm.

[0014] The material and shape of the grip portion 2 are not particularly limited, but it can be made of the same material as the shield body. As shown in Figures 8A to 8C, a bridge-shaped grip portion member 2a, formed by bending a belt-shaped plate material made of the same material as the shield body, can be attached to the body. The illustrated grip portion member 2a has a bridge portion 2b provided in the center of the belt-shaped plate material, with legs 2c and a base portion 2d bent at both ends, and a screw hole 2e is formed in the base portion. When this grip portion member 2b is screwed to the back surface of the shield body via the base portion, the bridge portion 2b is positioned at a predetermined height from the back surface of the shield body by the legs 2c. The shield user can manipulate the shield by inserting their hand from underneath the shield into the gap between the shield body and the bridge, grasping and lifting the bridge, and supporting the shield body with the back of their hand and forearm.

[0015] The shield main body 1 has a large, flat or nearly flat defensive wall portion 4, and an arbitrarily selected first side of the defensive wall portion 4 is provided with an impact defense portion 5 for receiving impact attacks with rod-shaped weapons, and a stab defense portion 6 for intimidating and defending against stabbing attacks to the abdomen with sharp weapons such as knives on a second side opposite the first side. The shield main body 1 also has a mountain-shaped thrust portion 7 protruding from the upper part of the large, flat or nearly flat defensive wall portion 4 for intimidating and counterattacking against attackers. Therefore, the control shield of the present invention has multiple defensive functions utilizing the impact defense portion and the stab defense portion, and also has intimidation and counterattack functions utilizing the thrust portion and the stab defense portion, and is therefore excellent in overall suppression power.

[0016] The impact defense section 5 has a rib structure 8 in which the edge of the first side section is bent toward the back side of the shield body along a bending axis running in the vertical direction of the shield body, and this rib structure increases the strength of the shield body against impacts. Figures 22A, 22B, and 22C are a series of photographs showing how, when struck from the upper front, one should start from the basic position, raise the elbow supporting the shield slightly, and point the shield in the direction the rod-shaped weapon is coming from to protect the head and chest. The rib structure 8 of the illustrated control shield 101 has a rib width W(lib) of 41 mm and a bending angle θ(lib) of 120 degrees. In the present invention, the width and bending angle of the peripheral portion that forms the rib structure of the impact defense section are not particularly limited, but generally, the rib width is set appropriately within the range of 41 to 45 mm, and the bending angle is set appropriately within the range of 120 to 132 degrees. Figures 9A and 9B show a modified example in which an impact defense section 5 is provided only on a portion of the first side of the shield body 1. Figure 9A is a front view showing the state in which the shield body material has a portion 5 (pre) that will become the impact defense section before being bent and shaped, and Figure 9B is a front view and a right side view showing the state in which the impact defense section 5 having a rib structure 8 has been formed after the shield body material has been bent and shaped. The impact protection section 5 may be provided on only a part of the first side portion as shown in the modified example of Figures 9A and 9B, but in order to widen the range of protection against impacts, it is preferable to provide it over a range extending from the upper end of the first side portion to at least half the length of the first side portion, and it is particularly preferable to provide it over the entire first side portion.

[0017] The stab defense part 6 has a continuous protrusion structure 10 in which a plurality of protrusions 9 formed in a mountain shape are arranged along the edge of the second side part. Each protrusion of the continuous protrusion structure protrudes from the edge of the second side part in the lateral direction of the shield body, and in a particularly typical case, has a mountain shape that protrudes in a direction parallel to the flat surface of the defensive wall part 4. This stab defense part can intimidate and counterattack against a stab attack from an attacker. Figures 23A and 23B are a series of photographs showing how, against a stabbing attack to the abdomen from the front, the shield body is lowered slightly with the second side facing downwards, the longitudinal direction of the shield body is held horizontal to protect the abdomen, and the continuous protrusion structure of the stab defense part is raised facing forward to intimidate and counterattack against an approaching sharp weapon such as a knife. The stab protection portion of the illustrated control shield 101 has a continuous protrusion structure 10 in which eight protrusions 9 are arranged across the entire second side portion, each having a height H of 17 mm in front view, a pitch W (pitch) of 50 mm, and an apex angle θ (side) of 90 degrees. In the present invention, the height, pitch, and apex angle of the protrusions 9 formed in the stab protection portion are not particularly limited, but are generally set appropriately within the ranges of 16 to 19 mm for the height, 50 to 55 mm for the pitch, and 90 to 99 degrees for the apex angle. 10 shows a modified example in which the stab defense part 6 having the continuous protrusion structure 10 is provided only on a part of the second side part of the shield body. The stab defense part 6 may be provided on only a part of the second side part, but in order to widen the defensive range against stab attacks, it is preferable to provide it over a range extending from the lower end of the second side part to half the length of the second side part, and it is particularly preferable to provide it over the entire second side part.

[0018] There are no particular restrictions on which of the two sides of the shield body the impact defense section 5 and the stab defense section 6 are placed on, but assuming the method of defense against impact or stab attacks as described above, when the user holds the control shield and control rod and assumes the basic posture in Figure 21, the impact defense section 5 is placed on the side on the same side as the hand holding the shield, and the stab defense section 6 is placed on the side opposite the hand holding the shield. For example, if the user holds the shield in their left hand, the impact defense section 5 is placed on the left side of the shield body as seen from the user, and the stab defense section 6 is placed on the right side of the shield body. Furthermore, assuming that a user generally holds the control rod in their dominant hand and the control shield in their non-dominant hand, when the user assumes the basic posture in Figure 21, the stab defense unit 6 is placed on the side facing the dominant hand, and the strike defense unit 5 is placed on the side facing the non-dominant hand. For example, if the user's dominant hand is the right hand and they hold the control shield in their opposite left hand, the strike defense unit 5 is placed on the left side of the shield body as seen from the user, and the stab defense unit 6 is placed on the right side of the shield body.

[0019] The thrust part 7 at the top of the shield body has a mountain-like shape that protrudes upward when viewed from the front, and in a typical case, is parallel to the flat surface of the defensive wall part 4, and this mountain-shaped pointed tip 11 is used to intimidate and counterattack an attacker. Figures 24A and 24B are a series of photographs showing how to counterattack by thrusting the thrust part at the top of the shield body against an attacker in front. The assault section 7 of the illustrated control shield 101 has a tip apex angle θ (top) of 81 degrees, and the apex of the tip is positioned at a point shifted a distance equivalent to one-eighth of the width of the shield body from the midpoint in the width direction of the shield body toward the first side section equipped with the impact defense section 5. In the present invention, the apex angle θ (top) of the striking portion is not particularly limited, but in order to increase the counterattack force, the apex angle is appropriately set in the range of 72 degrees to 81 degrees. The position of the apex of the tip of the thrust part is not particularly limited, but it is placed near the center of the width of the shield body to increase the counterattack power. The position of the apex of the tip is preferably placed slightly closer to the first side part where the impact defense part 5 is located than the midpoint of the width of the shield body, so that when the shield user assumes a basic stance, it is easier to see the front over the top of the side of the shield body where the stab defense part 6 is located. More specifically, it is preferably placed between the midpoint of the width of the shield body and a point that is one-quarter of the width of the shield body in the direction of the first side part. Figure 10 shows a modified example in which a thrust part 7 with two mountain-shaped pointed tips (11a, 11b) is provided on the top of the shield body. The thrust part may have more than two mountain-shaped pointed tips, but in that case, in order to make it easier to see the front view over the top of the side of the shield body where the stab protection part 6 is provided, it is preferable to position the apex of tip part 11a, which is closest to the stab protection part 6, between the midpoint of the shield body in the width direction and a point that is one-quarter of the width of the shield body in the direction of the first side part.

[0020] The control shield of the present invention may be equipped with various devices as needed. For example, a flashlight can be attached to the back of the control shield. The flashlight can be used not only to search the surroundings in the dark, but also to stop the movement of an attacker by suddenly shining the flashlight in their eyes. An attachment member that can detachably attach equipment is attached to the back of the control shield body, and various equipment can be freely selected and detachably attached to the back of the control shield via the attachment member. One such attachment member is a Picatinny rail (MIL standard: MIL-STD-1913), which is preferable because it can attach any equipment that is compatible with the Picatinny rail. As shown in Figure 3, a first various equipment attachment section 3a, to which any equipment can be detachably attached, may be provided above the grip section on the back of the shield body of the control shield, and a second various equipment attachment section 3b, to which any equipment can be detachably attached, may be provided on the upper surface of the grip section. In the example of Figure 3, the first various equipment attachment section 3a is positioned at an angle so that when a flashlight is attached, the light's irradiation direction is diagonally upward. The flashlight may also be attached directly to the second various equipment attachment section 3b provided on the upper surface of the bridge section of the grip section 2. 25A and 25B are photographs showing a first Picatinny rail as a first various equipment attachment section 3a located above the grip section on the back of the shield body, and a second Picatinny rail as a second various equipment attachment section 3b on the top surface of the bridge section of the grip section 2, with a flashlight attached to the first Picatinny rail and a controller connected to the flashlight attached to the second Picatinny rail 3b. Fig. 25A shows the control shield as seen from the back, and Fig. 25B shows the control shield as seen from the front. Fig. 25C shows the flashlight controller detached from the second Picatinny rail. The flashlight and controller may be connected wirelessly or by wire. Figures 26A, 26B, and 26C are photographs showing how to use a control shield with a flashlight attached to the first equipment attachment 3a located above the grip and a flashlight controller attached to the second equipment attachment 3b located on the grip. Figure 26A shows the control rod held in the right hand just before being raised. Figure 26B shows the control shield being raised slightly higher while the control rod is being raised to prepare for flashlight irradiation. Figure 26C shows the control rod being raised while the control shield is turned on, turning on the controller on the grip and aiming the flashlight at the attacker's eyes. As in this example, attaching the flashlight above the grip and positioning it at an angle diagonally upward relative to the vertical direction of the control shield is preferable because it allows for a height and angle of illumination that is easily aimed at the attacker's eyes. Also, attaching the flashlight controller to the top surface of the bridge of the grip is preferable because it allows for easy operation of the flashlight with the hand holding the grip. 27A and 27B are photographs showing how to shine a flashlight using a control shield with the flashlight attached directly to the second various equipment attachment section 3b on the grip section 2. In Fig. 27A, the control shield is raised slightly upwards while waving the control rod in the right hand to intimidate, and in Fig. 27B, the flashlight on the grip section is directly operated with the control rod still raised, and the flashlight is turned on, aimed at the attacker's eyes.

[0021] As shown in Figures 2 and 3, the flat protective wall 4 of the shield body may be provided with holes 12 for attaching restraints, fixators, tourniquets, and other necessary items. The shape of the holes 12 is not particularly limited, but in the illustrated example, a slit-shaped hole is provided through which a belt-like string can be passed. Figures 20A and 20B show the state in which necessary items are attached using the holes in the shield body. Figure 20A shows the state in which a tourniquet 13a is attached to the front side of the shield body, and Figure 20B shows the state in which a restraint belt 13b and a forearm fixation belt 13c are attached to the back side of the shield body.

[0022] II. Control Rods The control rod of the present invention is a sword-shaped control rod made of a long, thin plate-like material, having a control rod body with a stem portion at one end in the longitudinal direction and a shaft portion at the other end, and a grip portion provided on the stem portion of the control rod body, The hollow portion has a length of 490 to 540 mm and a width of 95 to 105 mm, The front end of the blade section is characterized by having, in order from the stem side toward the tip, a lower limb restraint section formed by molding a curved recess with a length of 260 to 290 mm and a maximum depth of 55 to 65 mm toward the ridge side of the blade section; an upper limb restraint section / striking section formed by molding a curved recess with a length of 110 to 125 mm and a maximum depth of 9 to 15 mm toward the ridge side of the blade section; and a thrust section / upper grip section with a length of 84 to 94 mm formed by molding a tapered cutting edge.

[0023] An example of a control rod (control rod 201) of the present invention is shown in Figures 11 to 17. Figure 11 is a six-view diagram of the control rod 201, Figure 12 is a front view, Figure 13 is a rear view, Figure 14 is a top view, Figure 15 is a bottom view, Figure 16 is a right side view, and Figure 17 is a left side view. In this specification, when the control rod is likened to a sword, the part corresponding to the blade of the blade is referred to as the front side, and a drawing in which the front side is drawn as if protruding from the page is referred to as a front view, the side corresponding to the ridge of the blade is referred to as the ridge side, and a drawing in which the ridge side is drawn as if protruding from the page is referred to as a back view, the part corresponding to the cutting edge of the blade is referred to as the tip, and a drawing in which the tip is drawn as if protruding from the page is referred to as a top view, the part corresponding to the stem of the blade is referred to as the stem part, and a drawing in which the stem part is drawn as if protruding from the page is referred to as a bottom view, a drawing in which the surface that would be on the right side when the front side is viewed from the front is referred to as a right side view, and a drawing in which the surface that would be on the left side when the front side is viewed from the front is referred to as a left side view.

[0024] The control rod 201 has a sword-like appearance with a grip portion 22 provided at one end of a control rod body 21 made of a long, thin plate-like material. The material of the plate-shaped material forming the control rod body can be appropriately selected from materials that have the necessary strength, rigidity, hardness, durability, and other characteristics for defense and counterattack, as well as formability and workability such as cutting, drilling, plastic processing, etc. For example, similar to the material for the control shield described above, metal-based materials such as aluminum alloy and stainless steel, engineering plastics such as polycarbonate and Kydex (registered trademark) (a high-impact acrylic modified resin manufactured by Sekisui Molding Co., Ltd.), and resin-based materials such as filler-added composite resins can be used. The control rod body 21 of the illustrated control rod 201 has a blade portion 23 corresponding to the blade of a sword, and a stem portion 24 provided at one longitudinal end of the blade portion. The boundary between the stem and the blade portion is the protrusion start point Px of a protrusion that protrudes toward the front of the control rod at the end of the stem closer to the blade portion, and this protrusion is part of the blade portion 23. The total length L of the control rod 201 is 606 mm, and the blade portion 23 has a length La of 490 mm, a width W in a side view (the maximum dimension between the front side and the ridge side of the blade portion) of 96 mm, and a plate thickness T of 5 mm. In the present invention, the overall length of the control rod and the overall length and width of the hollow portion are not particularly limited, but taking into consideration the corresponding sizes from small women to large men, the overall length L of the control rod is generally set appropriately in the range of 600 to 660 mm, and the hollow portion 23 is generally set appropriately in the range of 490 to 540 mm in length La and 95 to 105 mm in width W. The thickness T of the control rod body is not particularly limited, but is generally set appropriately within the range of 3 to 5 mm, taking into consideration sufficient defense and counterattack capabilities as a control rod, material properties, and weight.

[0025] The grip portion 22 is formed by attaching an easy-to-grip member to the stem portion 24 provided at one end of the control rod body. There are no particular restrictions on the material of the grip portion 22, and materials commonly used for the grip portions of knives and tools may be used. For example, the grip portion 22 can be formed by attaching a grip portion member made of wood, plastic, or other material by means of screws, rivets, or the like. In the illustrated example, the end 33 of the stem portion of the grip portion 22 is exposed on the hand side. The thickness of the grip portion 22 is generally set appropriately within the range of 15 to 17 mm, taking into consideration ease of gripping.

[0026] The front end of the drawing section 23 is provided with, in order from the stem 24 side toward the tip, a lower limb restraining section 25, an upper limb restraining section / striking section 26, and a thrusting section / upper grip section 27. Therefore, the control rod of the present invention has multiple intimidation and counterattack functions using the striking section and the thrusting section, and also has multiple restraint functions using the lower limb restraint section and the upper limb restraint section, so it has excellent overall restraining power.

[0027] The lower limb restraint section 25, the upper limb restraint section / striking section 26, and the thrust section / upper grip section 27 each have a curved recess that is recessed toward the ridge of the hollow section. The apex Pa of the protrusion protruding forward of the control rod near the boundary between the stem section 24 and the hollow section 23, the apex Pb of the convex section separating the lower limb restraint section 25 and the upper limb restraint section / striking section 26, and the apex Pc of the convex section separating the upper limb restraint section / striking section 26 and the thrust section / upper grip section 27 are aligned in a substantially straight line and have a height that is substantially the maximum width of the hollow section 23. Here, "substantially the maximum width" means that the difference from the maximum width of the hollow section 23 is 5.0 cm or less, preferably 3.0 cm or less, and particularly preferably 1.0 cm or less.

[0028] Lower limb restraint 25 has a curved recess 28 with a length Lb of 260 to 290 mm and a maximum depth Db of 55 to 65 mm toward the ridge side of the recess. Note that length Lb of curved recess 28 of lower limb restraint 25 refers to the length of the line segment connecting two points obtained by projecting two vertices Pa and Pb at both ends of curved recess 28 onto the longitudinal axis of the control rod, and maximum depth Db refers to the larger of two difference values ​​obtained by subtracting the width of the recess at the narrowest part of curved recess 28 from the width of the recess at the positions of the two vertices Pa or Pb at both ends of curved recess 28. As shown in the photograph in Figure 28, the interceptor can restrain the attacker by holding both ends of the lower limb restraint section 25 with both hands, with the peak of the exposed section facing up, inserting both lower limbs of the attacker into the curved recesses, and applying his / her body weight to hold down the attacker.

[0029] The upper limb restraint / hitting section 26 has a curved recess 29 with a length Lc of 110 to 125 mm and a maximum depth Dc of 9 to 15 mm toward the ridge of the shaft. The length Lc of the curved recess 29 of the upper limb restraint / hitting section 26 is the distance obtained by projecting the two vertices Pb and Pc at both ends of the curved recess 29 onto the longitudinal axis of the control rod. It means the length of the line segment connecting the two points, and the maximum depth Dc means the larger of the two difference values ​​obtained by subtracting the width of the cut-out portion at the narrowest part of the curved recess 29 from the width of the cut-out portion at the positions of the two vertices Pb or Pc at both ends. As shown in the photograph in Figure 29, the interceptor holds the ends of the upper limb restraining / striking section with both hands, with the peak of the drawn section facing up, and fits the attacker's upper limbs into the curved recesses, then applies his / her body weight to hold down the attacker, thereby restraining the attacker. The above-mentioned methods of restraining the lower and upper limbs, even when performed by a weak interceptor, cause great pain to the restrained person and take away their will to resist, making it difficult for the restrained person to escape.

[0030] The thrusting and upper grip portion 27 has a tapered tip 31 with a length Ld of 84 to 94 mm, and this tip is used to strike the attacker in a counterattack. By setting the lower limb restraint section 25, the upper limb restraint section and striking section 26, and the thrust section and upper grip section 27 within the above-mentioned dimensional ranges, not only can each section of the draw section perform the required function, but the center of gravity of the draw section is biased slightly toward the tip, so that the centrifugal force generated when the control rod is swung around can increase the striking force of the upper limb restraint section and striking section 26.

[0031] As shown in the photograph in Figure 28, the ridge of the upper limb restraint / striking section 26 is the position that is gripped by the hand when using the curved recess 28 of the lower limb restraint section 25 to subdue an attacker, so it is preferable that it has a shape that is easy to grip. Furthermore, as shown in the photograph in Figure 29, the ridge of the thrusting and upper gripping portion 27 is the position that is grasped by the hand when using the curved recess 29 of the upper limb restraint and striking portion 26 to subdue an attacker, so it is preferable that the ridge be shaped to be easy to grip. From this viewpoint, it is preferable that the front side of the thrusting and upper gripping portion 27 has a tapered shape with a curved recess 30 that is shallowly recessed on the ridge side, and that the ridge side portion opposite the portion extending from the upper limb restraint and striking portion 26 to the thrusting and upper gripping portion 27 has a curved recess 32 with vertices Pd and Pe at both ends, a length Le of 150 to 170 mm, and a maximum depth De of 20 to 25 mm toward the front of the cutting portion, and that a straight ridge portion 30 to 35 mm in length is left on the tip side of the vertex Pe of the cutting portion.

[0032] III. Control Shield and Control Rod Combination As is clear from the above, by using the control shield and control rod of the present invention in combination, it is possible to exert multiple different defensive functions, intimidation / counterattack functions, control functions, and restraint functions, thereby achieving excellent overall suppression power. Furthermore, since the shield body of the control shield of the present invention and the control rod body of the control rod of the present invention are both made of plate-like material and have a flat shape with a flat surface, by stacking the side of the removed part of the control rod facing the front of the shield body of the control shield, they can be stored without taking up much space. Furthermore, by combining a control shield with a support part, which has a support part formed by a first engaging member on the front surface of the shield body of the control shield of the present invention, and a control rod with a detachable part, which has a detachable part formed by a second engaging member that detachably engages with the first engaging member on at least one side surface of the shaft part of the control rod of the present invention, the control shield and control rod can be stored as a single unit in normal times to save space, and in an emergency can be carried as a single unit and rushed to the scene, and can be instantly separated upon arrival at the scene to prepare for an interception and respond immediately to an attack. 18A and 18B are diagrams showing an embodiment in which hook-and-loop fasteners are used as the first and second engaging members. Fig. 18A shows a control shield having a support portion 41 with a first hook-and-loop fastener in a region extending from the center of the width direction and the upper to middle portion in the vertical direction of the flat protective wall portion, and a control rod having a detachable portion 42 with a second hook-and-loop fastener in a region on the right side where the lower limb restraint portion is provided. Fig. 18B shows a state in which the control shield and the detachable portion of the control rod are detachably integrated by overlapping the support portion of the control shield and the detachable portion of the control rod facing each other. The first hook-and-loop fastener and the second hook-and-loop fastener have areas with sufficient bonding strength to prevent separation under the weight of the control rod when engaged.
