Description

  The present invention relates to a portable restraint net projection device for projecting a thief or suspicious person or a suspicious drone while deploying a restraint net, suppressing the behavior of the thief or suspicious person, or capturing a suspicious drone. In particular, the present invention relates to a restraint net projection device that can be used repeatedly by making it possible to easily reload the restraint net and its injection power source after use.

Patent Documents 1 to 8 disclose a restricted net deployment projection device or a device to which this is added. Most of them use combustion gas, pyrotechnic chemical reaction gas, or high-pressure non-combustion gas pressure as an injection power source for the restraint net, and a plurality of weights are ejected radially to form a mesh body locked to the weight. It is deployed and projected to the target.
US Pat. No. 5,326,101 Special table 2000-503142 Japanese Laid-Open Patent Publication No. 2006-084168 Japanese Laid-Open Patent Publication No. 2007-107863 JP 2007-164627 A Special table 2007-046194 public information JP 2008-304152 A JP 2010-121793 A

However, these devices according to the prior art are not only complicated and expensive, but especially those devices that use high-pressure gas generated by the chemical reaction of explosives or chemicals as a source of injection power. There was a problem in terms of possible lifetime. In addition, in principle, none of the devices according to the prior art assumes a user to reload the restraint network, and the manufacturer must collect and reload for reuse. The equipment was “disposable”.

Such a security / security device is originally intended for emergency response, and training including trial shooting is required for proper use in an emergency. However, for users with limited procurement budgets, trial firing using “disposable” equipment is very limited, so even if it is deployed, practical training is not sufficient, and it is impossible to deploy the necessary and sufficient number due to high costs. There was also a problem.

In addition, in each of the prior arts, a plurality of weights ejected radially project while projecting a restraint net, and the target is covered with a net body and entangled to try to suppress the action. However, depending on how the restraint net is covered, the movement of the target cannot always be sufficiently constrained, and there is a risk that the target may be separated from the restraint net or escape with the restraint net covered. For this reason, the restricted net | network deployment apparatus with a string of patent document 7 fixes the tough tension string attached to the weight of the restraint net to an apparatus, and the structure which raises an entanglement effect by pulling a string after projection is disclosed. However, depending on how the restraint net is covered, there is a possibility that a sufficient effect may not be exhibited.

Furthermore, in recent years, illegal use of drones (remote control or autonomous flying objects), which are becoming increasingly popular, has become a problem, but in order to capture or neutralize suspicious drones in advance due to security or safety needs. Utilization of a restraint net projection device is expected. However, in the prior art of the method of projecting the target to cover the restraint net from the upper side and the method of the method in which the restraint net is provided with a pull string, the range is shortened in the first place, so for drones that fly freely in the air Is not effective.

On the other hand, if it has a long range for a drone and does not have a pull string, it will reach the target before it is fully deployed when projected onto a target at a short distance, which is also effective. There is a risk of not. In an emergency situation, it is naturally impossible to predict in advance whether the target is a short-distance human or a long-distance drone, so it is difficult to deal with any target flexibly with a single restraint network projection device.

  The present invention has been created for the purpose of solving the problems of the prior art. Specifically, the restraint net projection device itself can be manufactured as a simple and simple structure as possible at low cost, and the user can re-use the restraint net and its injection power source after use of the device. This makes it possible to perform training by trial shooting at a low cost.

  In addition, in order for the restraint net projected and projected by the ejected weight to surely entangle the target, when the weight itself is ejected, the movement that causes the weight to entangle the restraint net to the target when it reaches the target. Specifically, it is desirable that the restraint net deployed in the air reaches the target while rotating.

  In addition, if the range of the restraint net projection can be switched based on the user's situation judgment, a single restraint net projection device can cope with both a relatively close-up gang and a suspicious person and a relatively long-range drone. it can.

  On the other hand, it is desirable to connect the restraint net and the restraint net projection device with a tow rope in order to prevent a thug and a suspicious person from easily escaping from the restraint net or escaping while wearing the restraint net. When the target is a drone, it is desirable to be able to release the connection so that the length of the towline does not limit the range.

  In order to solve the above-mentioned problem, the device according to claim 1 is a restraint net projection device comprising a restraint net and an ejector, and the restraint net includes a plurality of weights respectively connected to the net via a deployment cable. A plurality of injection pipes arranged radially at a predetermined angle in a direction perpendicular to the axis thereof, each of which can be loaded with the weight; and A restraint net accommodating portion capable of accommodating a restraint net inside the injection tube group, a replaceable gas cylinder filled with a high-pressure non-combustion gas, an opening mechanism for opening the gas cylinder by opening and extending a compressed spring, and An injection switch that activates the opening mechanism, and the injection switch group is operated by the pressure of the non-combustion gas by operating the opening mechanism by the injection switch and introducing the non-combustion gas in the gas cylinder into the injection tube group. Loaded And injecting a weight, characterized in that the expanded projection configured to be capable of the restraining net.

  According to such a configuration, the apparatus does not require any electrical mechanism and can have a very simple structure, so that it can be manufactured at low cost and does not require special maintenance. After use, the user can collect the restraint net, reload the weight into the injection pipe, fold the mesh body and re-store it in the restraint net housing, and then manually compress and fix the spring before gas cylinders. Is replaced with an unused one, and the constrained net projection device can be made reusable.

  A device according to a second aspect is the constrained net projection device according to the first aspect, wherein the injection tube group is radially arranged at a predetermined angle in an inclined direction with respect to the axis.

  Specifically, each injection tube is arranged so as to radially expand at a predetermined angle with respect to the axis of the apparatus, and at the same time, be inclined at a predetermined angle with respect to the axis in either a clockwise or counterclockwise direction. . With this configuration, the ejected weights are deployed in the air while flying in an obliquely outward direction with a predetermined inclination angle with respect to the axis of the apparatus. When the restraint net is fully deployed, a force that rotates the entire restraint net by a force vector in an oblique direction with respect to the axis of each weight acts, and the restraint net reaches the target while rotating. At this time, even after the net body covers the target and stops the rotational motion, the weight causes the net body to be entangled with the target by the remaining rotational motion. Thereby, compared with the case where a restraint net only covers a target, it can entangle a target more reliably and becomes difficult to detach | leave easily.

  The invention according to claim 3 is the restraint net projection device according to claim 1 or 2, wherein the injector further includes a changeover switch and a part of the non-combustion gas introduced from the gas cylinder. And an exhaust valve that can be discharged to the restraining net housing portion, and the exhaust valve can be opened and closed by operating the changeover switch.

  When the exhaust valve is in a closed state, all the pressure of the non-combustion gas ejected from the gas cylinder is conducted to the injection tube group, so that the injected weight flies at the maximum range. On the other hand, in the open state, a part of the non-combustion gas is discharged from the exhaust valve to the restraint net accommodating portion and the pressure transmitted to the injection pipe is reduced, so that the flying distance of the weight is shortened. By operating the change-over switch, the user opens the exhaust valve if the target is a relatively close-up or suspicious person, and closes the exhaust valve against a suspicious drone that flies away. The range of the net can be changed at any time.

  A device according to a fourth aspect is the device according to any one of the first to third aspects, wherein the restraint net is connected to the restraint net housing portion by a tow rope.

  With this configuration, in the same manner as the restraint net deployment device with a string described in Patent Document 7, when the restraint net is covered with the target and entangled, the user pulls the string and restrains the net body into the target body. The effect can be enhanced, and it is not easy for the target to escape while wearing the restraint net.

  The invention according to claim 5 is the restraint net projection device according to claim 4, wherein the restraint net housing portion has a locking mechanism that interlocks with the changeover switch, and the tow rope includes the locking mechanism. The locking mechanism is configured to release the locking of the tow rope when the changeover switch closes the exhaust valve, and when the exhaust valve is open. It is characterized in that the locking is effective.

  With such a configuration, when targeting relatively gangsters or suspicious persons, the lock switch is effective by setting the changeover switch to the open state of the exhaust valve. It can be deployed and projected at short range. On the other hand, when targeting a suspicious drone that flies away from the remote location, the tow rope is unlocked by setting the changeover switch to the closed state of the exhaust valve. Unexpected projection can be performed at the maximum range without being restricted.

  According to the first aspect of the present invention, a reusable restraint net projection device can be repeatedly manufactured with a simple structure and at a low cost, and the additional cost for reuse is only the cost of a replacement gas cylinder that is a consumable item. It is economical because it only takes The user can easily perform training including trial shooting, and the effect of improving emergency response capability can be expected.

  In addition, according to the second aspect of the present invention, since the deployed and projected restraint net can be rotated while flying, the target can be more effectively entangled after the restraint net is covered.

  Further, according to the inventions according to claims 3 to 5, the user can switch the range of the restraint net at any time according to the distance from the target, so that a gang or a suspicious person approaching with one restraint net projection device. And drones flying in the air can be targeted, and the effect of improving emergency response capability can be expected.

The restraint net projection device according to the present invention will be described below with reference to the drawings.
(First embodiment)
FIGS. 1-8 shows the restraint net | network projection apparatus NC1 concerning 1st Embodiment of this invention. The restraint net projection device NC1 includes a restraint net 1 and an injector 2 that injects the restraint net 1. 1 is a schematic view of a restraint net 1, FIG. 2 is a perspective view of an injector 2, FIG. 3 is a side view thereof, FIG. 4 is a sectional view thereof, and FIG. The restraint net 1 is composed of a substantially square net body 10 and a substantially bullet-shaped weight 11 respectively connected to deployment points 12 at eight arrangement points 12a on the outer peripheral edge thereof. The connection of the deployment cord 12 to the arrangement point 12a is a single bow and can be removed when the restraint net 1 is recovered after use. The weight 11 covers a metal main body 11a having a hole 11c for locking the deployable rope with a rubber outer shell 11b, thereby reducing the risk of hitting the target directly.

  The injector 2 includes a substantially conical head 2a and a main body 2b that is a hollow cylinder. The head 2a is composed of eight injection pipes 20 radially arranged at a predetermined angle in a direction perpendicular to the axis line from the base chamber 28, and a restraint net accommodating part 21 surrounded by them. Each injection tube 20 is loaded with a weight 11, and the front opening of the head 2 a is sealed by a circular cover 23 held by a detachable ring 22. The injection tube 20 gradually reduces the inner diameter from the opening tip toward the base to ensure the sealing property when the weight 11 is loaded. The main body 2b has a gas cylinder 24 filled with non-combustion gas and sealed at the front end in the cylinder, an opening mechanism 25 coaxially disposed in the hollow part 27 in the front of the cylinder, and an injection switch on the outer surface. 26. Further, the gas cylinder 24 can be loaded in a replaceable manner by removing the screw-in tail end 2c. The opening mechanism 25 is configured such that the needle 25b provided at the rear end thereof breaks the sealing of the front end of the gas cylinder 24 when the compressed spring 25a is opened by the operation of the injection switch 26 and extends rearward.

  When the opening mechanism 25 is operated by operating the injection switch 26 and the sealing of the gas cylinder 24 is broken, the high-pressure non-combustion gas in the cylinder is ejected into the hollow portion 27 and passes through the base chamber 28 of the head 2a. And introduced into the injection tube 20. The weight 11 causes the cover 11 to drop from the ring 22 and is ejected by the gas pressure, and then the deployment cable 12 pulls out the mesh body 10 to eject the restraint net 1. Furthermore, the ejected weights 11 fly while diffusing radially, thereby expanding the net 10 in the air. The restraint net 1 is formed by attaching one end of the tow rope 13 to the center of the net body 10, and the other end is fixed at the center of the innermost part of the restraint net accommodating part 21.

  FIG. 6 is a front view of the restraint net projection device NC1 with the cover 23 removed as viewed from the restraint net housing portion 21 side. The left figure shows the state before the restraint net 1 is loaded, and the right figure shows the state after the load. Eight injection pipes 20 are radially arranged so as to surround the restraint net accommodating portion 21, and a groove 20 c through which the deployment cord 12 passes when the weight 11 is loaded is provided at the edge of the opening of each injection pipe 20. ing.

  FIG. 7 is a continuous view showing a state in which the restraint net projection device NC1 is used and the restraint net 1 is ejected targeting a relatively close human P such as a thug or suspicious person. The user directs the injector 1 to the target at an appropriate elevation angle, operates the injection switch 26, and injects the restraint net 1. The restraint net 1 is ejected while the cover 23 is dropped due to the collision of the weight 11 and the tow rope 13 is pulled out, and the net 10 is unfolded during flight while covering the person P from above and restraining it. The movement of the human P is entangled in the net body 10 and its movement is suppressed, and if it tries to escape in this state, the restraint net 1 pulled by the tow rope 13 further bites into the body, making it difficult to escape. A plurality of tow ropes 13 may be provided, and the restraining effect can be enhanced by fixing the other end of the towing rope at an appropriate position on the outer peripheral edge of the restraint net 1.

  FIG. 8 is a schematic diagram showing a method of reusing the injected restraint net 1 after using the restraint net projection device NC1. The user removes the entanglement of the collected restraint net 1, folds the net body 10 into an elongated shape, inserts the ring 22 into the restraint net accommodating portion 21, and then sequentially reloads the weight 11 into the injection tube 20. Finally, the ring 22 in which the cover 23 is reinserted is attached. When folding the restraint net 1 together, it is possible to prevent the weight 11 and the deployment cord 12 from being entangled with the net body 10 by locking the weight 11 to the disc-like weight holder 11d. When the entanglement of 1 is released, the work becomes easier if the deployment cord 12 is removed from the arrangement point 12a in advance. Next, the tail end 2c is removed, the used gas cylinder 24 is taken out, a rod-like tool (not shown) is inserted, the opening mechanism 25 is pushed in, the spring 25a is compressed, and the injection switch 26 is returned and fixed. Finally, if the replacement gas cylinder 24 is loaded and the tail end portion 2c is mounted, the gas can be reused.

(Second Embodiment)
FIG. 9 is a schematic view showing an arrangement state of the injection pipe 20 in the restraint net projection device NC2 according to the second embodiment of the present invention in comparison with the first embodiment. The other configurations of the second embodiment are the same as those of the first embodiment.

  In the first embodiment (left figure), all of the eight injection tubes 20 are converged toward one point on the axis of the restraint net projection device NC1 at the base, and each injection tube 20 is perpendicular to the axis. They are arranged radially at a predetermined angle. On the other hand, in the second embodiment (right figure), each injection tube 20 is arranged at the base so as to be shifted from the axis of NC2, and each injection tube 20 is radially expanded at a predetermined angle with respect to the axis of NC2, and at the same time, On the other hand, they are arranged radially at a predetermined angle in a clockwise tilt direction. Specifically, as shown in FIG. 9, in the first embodiment NC1, the injection pipe 20 has an axis line connecting the inlet 20 b opened to the base chamber 28 and the outlet 20 b opened at the tip of the head 2 a with respect to the axis of the injector 2. Appear vertically. On the other hand, in the second embodiment NC2, the inlet 20b is opened at a position shifted clockwise when viewed from the front, and the axis connecting the inlet 20b and the outlet 20a is inclined with respect to the axis of the injector 2.

  With this configuration, in the second embodiment, the ejected weight 11 expands the restraint net 1 in the air while flying obliquely outward with a predetermined inclination angle with respect to the axis of the ejector 2. And the force which rotates the whole restraint net | network 1 by the torque which generate | occur | produces in the diagonal direction with respect to an axis acts, and the restraint net | network 1 reaches | attains a target, rotating.

(Third embodiment)
FIG. 10 shows a cross-sectional configuration of the head 2a of the restraint net projection device NC3 according to the third embodiment of the present invention. The other configurations of the third embodiment are the same as those of the second embodiment.

  The difference from the second embodiment is that an exhaust valve 29 and a locking mechanism 30 are provided in the center of the innermost part of the restraint net accommodating portion 21, and a changeover switch 31 that can be operated in conjunction with the outside is further provided on the outer side. It is a point that is provided. The locking mechanism 30 fixes the other end of the tow rope 13 in the connected state and opens the other end in the released state. The changeover switch 31 is configured so that the user can select between the short range side and the long range side.

  When the changeover switch 31 is set to the short range side, the exhaust valve 29 is open and the locking mechanism 30 is connected. In this state, a part of the non-combustion gas introduced into the base chamber 28 from the gas cylinder 24 through the hollow portion 27 at the time of injection is discharged from the exhaust valve 29 into the restraint net accommodating portion 21, so that the inside of the injection pipe 20 As a result, the gas pressure conducted to the air decreases and the flight distance of the restraint net 1 is shortened. Further, since the locking mechanism 30 is connected, the restraint net 1 is maintained in a state where it is connected by the injector 2 and the tow rope 13.

  On the other hand, when the changeover switch 31 is set to the long range side, the exhaust valve 29 is closed and the locking mechanism 30 is released. In this state, all the pressure of the non-combustion gas is conducted to the injection pipe 20, so that the restraint net 1 is injected at the maximum range. Further, since the locking mechanism 30 is released, the tow rope 13 and the injector 2 are not connected, and the restraint net 1 can fly without being restricted by the length of the tow rope 13.

  FIG. 11 is a continuous diagram showing a state in which the restraint net 1 is ejected by using the restraint net projection device NC3 and targeting the suspicious drone D flying in the air at a relatively long distance. The user sets the changeover switch 31 to the long range side in advance, directs the injector 1 to the target at an appropriate elevation angle, and operates the injection switch 26 to inject the restraint net 1. The restraint net 1 is ejected while rotating, deploys the net body 10 during flight, covers the target D from the side, entangles it, and drops it.
