Description

  The present invention relates to a mobile protective shield for protecting against bullets, firearms, and the like, and a simple protective team formed by joining a plurality of them.

  In the world, struggles due to territorial disputes, ethnic conflicts, rich and poor differences, religious conflicts, etc. have not been exhausted since history, and each country's army or police unit is not war, terrorism or undemocratic. Various forms of protection are used to protect civilians, soldiers or important bases from demonstrative demonstrations. For example, bulletproof vests, blade-proof vests, and protective shields are used as the simplest and most effective means for protecting human lives.

  Currently, common protective shields used by police or military units are lightweight and portable, made of metal or reinforced plastic. Such a protective shield has the advantage that a police or military unit engaged in security has it, and it is easy to evacuate or advance towards the enemy. As such a protective shield, what consists of a flat plate or a curved plate which has a handle inside a shield is known (for example, refer to patent documents 1). A self-supporting protective shield having a folding stand inside the shield is also known (see, for example, Patent Document 2). Furthermore, there is also known a protective shield that includes a bullet protection plate for preventing a bullet from entering the inside of the protective shield from the vicinity of the lower part of the protective shield and has improved protection characteristics (see, for example, Patent Document 3).

  However, the protective shields disclosed in Patent Document 1 and Patent Document 2 have the advantage of having a simple structure and being portable, but they protect police and military personnel from weapons that are more aggressive than handguns. Is not enough. If a steel plate thicker than the current protective shield is used for the impact surface, the protection can be further enhanced. However, when such a heavy shield is used, the degree of freedom of carrying is reduced, and it is difficult to effectively prevent an attack from the enemy or to advance toward the enemy. For this reason, the police or the military demands a protective shield that achieves both protection and mobility.

  On the other hand, the protective shield disclosed in Patent Document 3 has both protective properties and mobility. It is preferable to connect a plurality of such protective shields so that a large wall can be easily formed. On the other hand, when the location of the protection target is changed, it is necessary to disassemble the walls into individual protection shields and move them. The protective shield preferably has a height equal to or higher than the height of a human being because of its protective properties. Further, it is preferable that the length of the protective shield in the width direction is as wide as possible from the viewpoint of realizing stable independence of the protective shield. From the viewpoint of weight reduction, it is preferable to keep the size so as not to protrude when a human is standing and not to make it wider than necessary. In order to achieve both such size and weight reduction, a structure is considered in which the wheels necessary for moving the protective shield are widened so that the width of the shield is within the width of both wheels in the width direction. However, if the wheel protrudes beyond the width of the protective shield, another problem arises that it is difficult to connect the protective shield in the width direction. In particular, when an attack is received while using the protective shield alone, the risk of damaging a protected object such as a person behind the protective shield increases unless the protective shield is stable and independent.

  In order to facilitate connection of the protective shield in the width direction and to realize stable independence when used alone, the bullet protective plate disclosed in Patent Document 3 is extended toward the ground, and the left and right widths of the bulletproof plate A method of reducing the risk of falling in the direction is also conceivable. However, if there is a gap between the bouncing protection plate and the ground, there is a risk that the protective shield will sway from side to side, and when the protective shield is moved from fixed to fixed or moved from fixed, it is necessary to ensure safety. It is necessary to switch the expansion and contraction of the bullet protection plate. From such a point of view, the protective shield disclosed in Patent Document 3 does not necessarily satisfy the request sufficiently.

  The present invention has been made in view of the above problems, and is excellent in protective properties, mobility and width direction connectivity, can realize stable independence even when used alone, and can be quickly switched between movement and fixation. It is an object of the present invention to provide a protective shield that can easily cope with the above, and a simple protective team in which a plurality of them are joined.

  To achieve the above object, a mobile protective shield according to an embodiment includes a bulletproof plate, a support member that supports the bulletproof plate from the back side, and at least a pair of first wheels arranged in the width direction of the bulletproof plate. A shutter capable of opening and closing a gap between the bulletproof plate and the ground, and an opening / closing operation portion which opens and closes the shutter from the back side of the bulletproof plate and has a stepping lever, and has at least a pair of first wheels Are arranged at intervals smaller than the width of the bulletproof plate, and the shutter can be lowered to a position in contact with the ground by operating a stepping lever.

  In the mobile protective shield according to another embodiment, a foot-operated lever may be separately provided to respectively perform the lowering and raising of the shutter.

  In the mobile protective shield according to another embodiment, the bulletproof plate includes a window portion made of ballistic glass or resin above the half of its height, and the window is formed from the bottom of the bulletproof plate.

  In the mobile protective shield according to another embodiment, at least the pair of first wheels may be arranged directly below the bulletproof plate or on the front side of the bulletproof plate.

  In the mobile protective shield according to another embodiment, at least the pair of first wheels may be at least one of an irregular terrain tire, a caster, and a roll tire made of metal or resin.

  The mobile protective shield according to another embodiment further includes at least one second wheel fixed to the support member in the direction of the back side of the bulletproof plate with respect to at least the pair of first wheels. May be provided with a stopper capable of switching between rotation and fixation.

(1) Structure of bulletproof plate The mobile protective shield 1 according to this embodiment includes a bulletproof plate 2 that is substantially rectangular when viewed from the attack side (also referred to as the front side), and the bulletproof plate 2 that is connected to the protective side (also referred to as the rear side). A support member 3 that supports the front, 17 and 17 as a pair of first wheels that can be movably grounded on the bulletproof plate 2, and rear wheels 37 and 37 as a pair of second wheels that can also be grounded. . The bulletproof plate 2 is perpendicular to the angle of the plate-like body (also referred to as a rectangular parallelepiped) that occupies substantially the upper half of the ground with respect to the angle of the portion of the plate-like body (also referred to as a rectangular parallelepiped) that occupies the substantially lower half of the ground. It is a bent plate member having a close angle. In this embodiment, the substantially upper half located above the one-dot chain line X in FIG. 1 of the bulletproof plate 2 is preferably inclined at an acute angle toward the support member 3 in the range of 85 to 90 degrees with respect to the ground. doing. Further, the substantially lower half of the bulletproof plate 2 located below the one-dot chain line X in FIG. 1 is preferably inclined at an acute angle toward the support member 3 in the range of 77 degrees to 84 degrees with respect to the ground. The angle θ formed by the substantially upper half plate surface and the substantially lower half plate surface is preferably an obtuse angle (an angle greater than 90 degrees and less than 180 degrees), and more preferably 167 degrees or more and 179 degrees or less. It is a range. The angle (angle a) formed by the substantially lower half and the horizontal surface on the back side is not particularly limited as long as it is an acute angle. Further, the angle (angle b) formed by the substantially upper half described above and the horizontal surface on the back side thereof is an acute angle, a right angle, or an obtuse angle, and is not particularly limited as long as the angle is closer to the right angle than the angle a.

  The substantially upper half of the bulletproof plate 2 includes an upper side frame 10 that constitutes the upper side, first side frames 11 and 11 that constitute both sides in the width direction, and a first side that constitutes the attack side surface (also referred to as the front surface). The front panel 13 and the transparent window part 14 as a window part arrange | positioned in the area | region enclosed by each flame | frame 10,11,11 and the 1st front panel 13 are mainly provided. The first front panel 13 is a plate frame member having a rectangular outer shape with a rectangular opening 13b in the plane. The transparent window part 14 is arrange | positioned at the back side of the 1st front panel 13, and a part of front surface of the transparent window part 14 is exposed to the opening part 13b. The upper side frame 10 is preferably a double-ended square tube having a hollow inner region in the axial direction. The first side frames 11, 11 are substantially U-shaped cross sections having rail-shaped recesses on the surfaces facing the respective sides of the transparent window portion 14. The transparent window portion 14 and the upper frame 10 constitute a substantially upper half of the bulletproof plate 2 in a state sandwiched between the first side frames 11 and 11 from both the left and right width directions of the bulletproof plate 2. In this way, the bulletproof plate 2 includes the transparent window portion 14 as a window portion made of a ballistic-resistant glass or resin above a position approximately half of its height, and the transparent window portion from the lowermost portion of the bulletproof plate 2. 14 up to a middle position is an inclined portion 2b inclined in a direction to cover the back side of the bulletproof plate 2, and the upright portion 2a having an angle closer to the upright than the inclined portion 2b is formed above the inclined portion 2b of the bulletproof plate 2. The bulletproof plate 2 is configured by connecting an inclined portion 2b and an upright portion 2a provided with a transparent window portion 14.

  When the bulletproof plate 2 is composed of the upright portion 2a and the inclined portion 2b, the following actions and effects can be obtained. First, when the inclined portion 2b receives a bullet from the attacking side, the bullet cannot penetrate the inclined portion 2b unless it travels a distance in the horizontal direction that is equal to or greater than the thickness of the inclined portion 2b. . In addition, when the inclined portion 2b is formed, resistance to blast and natural wind is also reduced. For this reason alone, it is preferable to incline the entire bulletproof plate 2 at the same angle as the inclined portion 2b. However, when the transparent window portion 14 is inclined, when the bullet hits the transparent window portion 14, the cobweb-like cracks spread over a wide range, making it difficult to visually recognize the attack side through the transparent window portion 14. . In order to improve the visibility of the transparent window portion 14, it is preferable to provide the transparent window portion 14 on the bulletproof plate 2 at an angle close to perpendicular to the bullet traveling direction as much as possible. In this way, in order to achieve both the protection characteristics of the bulletproof plate 2 and the visibility of the transparent window portion 14, a portion including the transparent window portion 14 is formed at an angle close to the vertical direction with respect to the horizontal direction. It is preferable that the lower portion is inclined at an acute angle with respect to the horizontal direction and falls to the support member 3 side.

  The first front panel 13 includes poles 13a, 13a, 13a, 13a with thread grooves protruding to the back side at the four corners of the protective side (also referred to as the back side).

The suspension member 42 is a string-like member having ring-shaped attachment portions 42a and 42c at both ends in the length direction. The attachment portion 42a at one end of the suspension member 42 is fixed to the hole 41a of the shutter 41, and the attachment portion 42c at the other end portion is fixed to a portion that is driven in the vertical direction in the opening / closing operation portion 40. The two holes 41b formed in the vicinity of both ends in the width direction of the shutter 41 are portions that are fixed with nuts from the back through bolts, and are not connected to the suspension member 42.

  When the part fixed to the attachment part 42c of the suspension member 42 is moved up and down by the operation of the opening / closing operation part 40, the shutter 41 fixed to the attachment part 42a of the suspension member 42 is also moved in the vertical direction indicated by the arrow A. The shutter 41 preferably moves up and down in a gap formed at the substantially center in the front-rear direction in the shutter holding member 36 that is elongated in the width direction when viewed from above the bulletproof plate 2. The bolt passed through the hole 41b and the nut fixed from the back side serve as a stopper that prevents the shutter 41 from sliding down from the gap of the shutter holding member 36. As a result, it is possible to effectively prevent the shutter 41 from falling downward from the gap of the shutter holding member 36 even when the suspension member 42 is cut during manufacture / assembly or transportation of the mobile protective shield 1.

  FIG. 7 is a partially transparent side view of the vicinity of the shutter and the opening / closing operation unit in FIG. 6 (6A) as seen from the side. FIG. 8 is a perspective view of the state in which the shutter of FIG. 6 (6A) has moved upward as seen from the back side of the bulletproof plate. FIG. 9 shows a perspective view of the state in which the shutter of FIG. 6 (6A) is moved downward and grounded, as viewed from the back side of the bulletproof plate.

  The opening / closing operation unit 40 includes two types of pedals (preferable examples of stepping levers) 43 and 44 that can be operated by stepping, a first cylindrical member 45 fixed to the upper surface of the shutter holding member 36, And a second cylindrical member 46 which is disposed on the upper portion of the cylindrical member 45 and can move up and down while covering the outside of the first cylindrical member 45. When the pedal 43 is depressed, the shutter 41 moves upward. On the other hand, when the pedal 44 is depressed, the shutter 41 moves downward. The pedal 43 has one end of each of two thin bending levers 47 that are bent in a boomerang shape in plan view at both ends in the width direction. The other end of the bending lever 47 opposite to the pedal 43 is connected through a shaft 49 and a linear lever 48 that is substantially linear in plan view and is thin. The two bending levers 47 are attached to the first cylindrical member 45 in such a state that a shaft 50 penetrating the substantial center of the inner diameter from the side surface of the first cylindrical member 45 passes through the bent portions. Further, the two bending levers 47 and the two linear levers 48 are in a state in which the shaft 49 is passed through the connecting portion, and on both sides of the first cylindrical member 45 and the second cylindrical member 46 (the front and back sides of FIG. 7). (Direction) is disposed on the opening / closing operation unit 40. The shaft 49 is movable within a predetermined range from the attacking side (front side) surface of the second cylindrical member 46 to the back side surface of the bulletproof plate 2 when the pedal 43 is operated.

  The bending lever 47 rotates around the shaft 50 when the pedal 43 is depressed. Further, the bending lever 47 and the linear lever 48 can be rotated by changing the angle around the shaft 49 like a joint. The second cylindrical member 46 includes a top plate 51 on its upper surface that extends long from the upper surface of the second cylindrical member 46 in the direction of the back side surface of the bulletproof plate 2. The top plate 51 is fixed through a shaft 52 extending in the front and back direction in FIG. 7 in a state where an end portion in the back side direction of the bulletproof plate 2 is sandwiched between two linear levers 48 in the width direction. For this reason, the linear lever 48 can be rotated around the shaft 52 while changing the angle with the side surface of the top plate 51. The two suspension members 42 are held by the top plate 51 in a state where the shaft 53 is passed through the attachment portions 42c. For this reason, when the top plate 51 moves up and down, the shutter 41 can move up and down accordingly.

  The pedal 44 is an elongated linear member. One end of the pedal 44 is a surface of the second cylindrical member 46 in the back direction of the linear lever 48 arranged in the reverse direction of the paper surface of FIG. 54 is fixed. The pedal 44 and the linear lever 48 are connected with their angles fixed. When the pedal 44 is stepped on, the shaft 49 of the linear lever 48 protrudes toward the back side of the bulletproof plate 2, and the top plate 51 moves downward accordingly. For this reason, the shutter 41 connected via the shaft 53 and the suspension member 42 also moves downward. FIG. 9 shows a state in which the pedal 41 is depressed to move the shutter 41 downward (in the direction of arrow B) so that the gap from the lower end of the bulletproof plate 2 to the ground is zero.

  On the other hand, when the pedal 43 is stepped on, the bending lever 47 rotates about the shaft 50 and the shaft 49 rotates upward so as to approach the direction of the second cylindrical member 46. Move upward. As a result, the top plate 51 moves upward from the state shown in FIG. 9, and the shutter 41 connected via the shaft 53 and the suspension member 42 also moves upward, resulting in the state shown in FIG. As described above, the shutter 41 can be moved up and down through the alternate operation of the pedal 43 and the pedal 44.

  The shutter 41 is a thin plate that is long in the left-right width direction of the bulletproof plate 2, and is preferably pierced into the ground if it is grounded or earthed when lowered. As a result, even if the widths of the front wheels 17 and 17 are narrow, the shutter 41 is grounded in the left-right width direction of the mobile protective shield 1, so that the mobile protective shield 1 is unlikely to fall down in the left-right width direction. In order to make this effect particularly effective, the length of the shutter 41 (the distance in the left-right width direction of the bulletproof plate 2) is equal to or longer than the distance between the front wheels 17, 17 (the distance between the centers of the widths of the front wheels 17). It is preferable. Further, the shutter 41 can exhibit the following two advantages. The first advantage is that the shutter 41 becomes a resistance to move backward against an impact or blast from the attacking side of the mobile protective shield 1. In particular, when the shutter 41 is pierced into the soil ground, the effect is increased. Another advantage is that the shutter 41 can effectively shield flames from bullets and flame bottles that jump up from below the bulletproof plate 2.

  Such a plurality of advantages are all obtained when the shutter 41 is moved downward. However, the mobile protective shield 1 is not used while being fixed at one place, but needs to be moved quickly according to the attack situation from the enemy. For this reason, it is necessary to quickly move the shutter 41 upward when moving, and to rapidly move the shutter 41 downward when fixed. In order to meet such a request, the operability of the opening / closing operation unit 40 needs to be improved. The opening / closing operation unit 40 in this embodiment includes a stepping lever that can be operated by stepping. For this reason, it is not necessary for a person on the back side of the protective plate 2 to fall down, and the shutter 41 can be moved up and down by the force of the foot. In general, hand-operated operations are particularly difficult when wearing gloves or holding weapons. In this respect, enabling the shutter 41 to be moved up and down by foot operation has a great advantage. Furthermore, since the part where the shutter 41 is moved up and down is divided into two types of pedals 43 and 44, the shutter 41 is erroneously operated by stepping on the same pedal many times more confusingly than when the same pedal is operated up and down. Therefore, it is difficult to cause a situation of moving upward or downward.

2. Next, a preferred embodiment of the simple protective guard according to the present invention will be described with reference to the drawings. In addition, in the components of the simple protective team, the same components as those of the mobile protective shield described above are denoted by the same reference numerals and replaced with the previous description, and the redundant description is omitted.

  FIG. 10 is a simple protective armor according to an embodiment of the present invention, and two mobile protective shields of FIG. 1 are prepared and attacked by connecting them in the width direction of each other. The perspective view seen from the side (front side) is shown. FIG. 11 is a perspective view of the simplified protection team of FIG. 10 as viewed from the protection side (rear side). FIG. 12 shows an enlarged view (12A) in which a part of the upper part of FIG. 11 is enlarged and a partially transparent plan view (12B) that is partially transparently shown from above. FIG. 13 shows an enlarged view of a part of the lower part of FIG.

  The simple protective guard 70 according to this embodiment is formed by joining a plurality of mobile protective shields 1. 10 to 13 exemplify a simple protective arm 70 in which only two mobile protective shields 1 are joined (also referred to as connection), but a simple type in which three or more mobile protective shields 1 are connected. You may build a guard. In the simple protective arm 70, two adjacent bulletproof plates 2, 2 are connected by a first connecting member 60, and two adjacent support members 3, 3 are connected by a second connecting member 75. The outer peripheral edge of a general bulletproof plate is a portion with low bulletproof performance. Therefore, when two bulletproof plates are connected, there is an area where the bulletproof performance is reduced by a certain width at the joint (connecting portion). In order to reinforce this area, a method of securing bulletproof performance by superimposing a reinforcing bulletproof plate that is elongated (for example, about 100 mm in width) from the front surface or the back surface of the joint portion (connecting portion) is used. On the other hand, in this movable protective shield 1, by arranging the first side frame 11 (or the second side frame 12) having a substantially U-shaped cross section at the left and right ends of the bulletproof plate 2, When the mobile protective shield 1 is connected, the back sides of the U-shaped frame 11 (or 12) are in close contact with each other. As a result, even if a bullet enters the connecting portion of the bulletproof plate 2 as indicated by the black arrow in (12B), the bullet toward the protective side is caused by the presence of the U-shaped frame 11 (or 12). Can be prevented. Thus, since the movable protective shield 1 can be connected without using a reinforcing bulletproof plate, the simple protective arm 70 can be easily formed.

  The first connecting member 60 is a plate-like member, and is attached to the back surface so that the plate surface overlaps the back surface of the first side frame 11 on the back side of the bulletproof plate 2. As shown in FIG. 12, the first connecting member 60 is fixed so that one end side thereof can be rotated by a shaft 61. A groove 62 extending inward from one side of the plate surface is formed at the end of the first connecting member 60 opposite to the shaft 61. Formed on the back surface of the first side frame 11 is a first convex portion 63 that is spaced apart from the shaft 61 by a certain distance and has the same shape as the shaft 61 and protrudes to the protection side. When the mobile protective shields 1 are not connected to each other, the first connecting member 60 is fixed to the back surface of the first side frame 11 with the groove 62 fitted into the first convex portion 63. On the other hand, on the back surface of the first side frame 11 on the side where the shaft 61 of the movable protective shield 1 is not formed, a second convex portion 64 protruding to the protective side is formed at substantially the same height as the shaft 61. Yes. The distance between the shaft 61 and the first convex portion 63 is equal to the distance between the shaft 61 and the second convex portion 64. When connecting the movable protective shields 1 to each other, the first connecting member 60 is rotated around the shaft 61 and the groove 62 is fitted into the second convex portion 64. Since the groove 62 is opened downward, as shown by an arrow C, the first connecting member 60 is rotated about the shaft 61 and once passed through the second convex portion 64, It is preferable that the second protrusion 64 is fitted in the direction of rotation.

  As shown in FIG. 13, the second connecting member 75 is a handle-type connecting member. The second connecting member 75 is formed in a hole 73 formed in a part of the wheel fixing part 30 of one mobile protective shield 1 and in a part of the wheel fixing part 30 of the other mobile protective shield 1. The holes 74 are used by inserting end portions on both sides thereof. The mobile protective shield 1 is preferably provided with a hole 73 at the left end of the left wheel fixing portion 30 when viewed from the back side of the mobile protective shield 1 so that another mobile protective shield 1 can be connected to both sides in the width direction. A hole 74 is formed at the right end of the right wheel fixing portion 30 as viewed from the back side of the mobile protective shield 1.

3. Next, a preferred embodiment of a traction tool detachably attached to the mobile protective shield of the present invention will be described with reference to the drawings.

  The traction tool 80 is located between two horizontally long bars 81 and 83, and has four longitudinal bars 91, 92, 93, and 94 that are long in the longitudinal direction of the bulletproof plate 2 from the front side surface of the bulletproof plate 2 toward one point in the front. And a mounting portion 96 that can be attached to the vehicle at one point in front of the vehicle. Here, “one point” does not mean a point in a strict sense, but is a region having a predetermined area, and the longitudinal bars 91, 92, 93, 94 are fixed to the longitudinal bars 82, 82. It is sufficient if the area is smaller than the area surrounding the point. The attachment portion 96 is joined to the front end portion of the four front and rear long bars 91, 92, 93, 94 through the flange portion 95. The flange portion 95 is configured by fixing a plate-like member fixed to the four front and rear long bars 91, 92, 93, 94 and a plate-like member fixed to the attachment portion 96 with bolts and nuts. . The attachment portion 96 is a rod-like member extending from the flange portion 95 in the opposite direction of the front and rear long bars 91, 92, 93, 94, and includes a ring portion on the opposite side to the flange portion 95. The ring portion is a portion that can be fixed to a part of the vehicle. However, a hook may be employed instead of the ring portion.

  The front / rear long bar 91 and the front / rear long bar 93 connect the vicinity of both ends of the third horizontally long bar 84 to the flange portion 95. The front / rear long bar 92 and the front / rear long bar 94 connect the vicinity of the joint of the two vertically long bars 82, 82 with the first horizontally long bar 81 to the flange portion 95. The four front and rear long bars 91, 92, 93, 94 form a quadrangular pyramid skeleton by combining the two vertical bars 82, 82, the first horizontal bar 81, and the third horizontal bar 84.

However, instead of the metal material, other kinds of metals or ceramics may be used. In particular, the four front and rear long bars 91, 92, 93, 94 are preferably formed of a highly rigid material that cannot expand and contract under normal use conditions. This is because the distance between the mobile protective shield 1 and the vehicle is constant when the traction tool 80 is fixed to the mobile protective shield 1 and the vehicle is run with the mounting portion 96 of the traction tool 80 fixed to the vehicle. This is because it can be towed while being held in the door.
