That is, the switch 56 is turned off when the movable terminal is at the first position, and turned on when the movable terminal is at the second position.

  The main body member 50 is provided with an insertion hole through which the switch plate 61 is inserted at an end opposite to the one end where the cylindrical portion 35a of the first component member 35 is attached. In the case of a product of the carrying side restraint net deployment device 10, the guide path of the switch plate 61 is formed by the insertion hole provided in the main body member 50 and the gap between the lower surface of the cover 51 and the upper surface of the switch 56.

  For example, when the switch plate 61 is inserted into the guide path, the switch button provided on the switch 56 is housed inside the box-like container, and the button head is held in contact with the switch plate 61. That is, the switch 56 is turned off. On the other hand, when the switch plate 61 is pulled out of the guide path, the switch button protrudes from the box-shaped container. That is, the switch 56 is turned on. Here, when the switch 56 is turned on, the trigger member 62 formed of a ball chain attached to one end side of the switch plate 61 is pulled to pull out the switch plate 61 from the guide path. In addition, although the ball chain is taken up as the trigger member 62, if it is strong, it may be a chemical fiber.

  The grip cover 52 is an elastic body such as an elastomer, for example. The grip cover 52 has a tubular shape. The flip cover 52 is attached to the outer peripheral portion of the main body member 50 to which the cover 51 is screwed. The outer peripheral surface of the grip cover 52 has an uneven shape, and has a function of anti-slip when held by the user.

When the fix cup 27 is screwed and fixed to the restraining net spouting portion 25, the annular bulging portion 50 a provided at the one end portion of the main body member 50 for preventing removal is provided with the retaining piece 27 a provided inside the fix cup 27 It is nipped between the ejection portion 25 and the container 30 (specifically, the first component 35). Reference numeral 66 denotes a seal that covers the head of the screw 65.

  Next, the manufacture of the portable restraint network deployment apparatus 10 will be described. First, the restraint net spout 25 is manufactured. The container 30 is manufactured by screwing and fixing the first component 35 and the second component 36 after alignment. In the manufactured container 30, the opening of the second component 36 is exposed. The sleeve 31 is inserted into the inside of the opening of the second component 36 of the container 30 and then held along the inner peripheral surface of the second component 36. Then, the other end side in the width direction of the sleeve 31 extending to the outside from the opening portion of the second component member 36 is folded back so as to be located outside the outer peripheral surface of the second component member 36 (FIG. )reference).

  Then, the folded restraint net 20 is accommodated inside the opening portion of the second component 36. Thereafter, the restraint net 20 is pushed into the interior of the second component 36 by the jig 70 (see FIG. 4B).

  The weights 21 attached to the restraint net 20 are respectively held by the jigs 70. In a state where the constraining net 20 is pushed into the inside of the second component 36 by the jig 70, the folded back portion of the sleeve 31 is returned to the original state. After moving the jig 70 upward, the string members for attaching the weight 21 to the restraint net 20 are put together. A portion of the sleeve 31 extending to the outside from the second component 36 is folded toward the second component 36 (see FIG. 4C).

  One end in the width direction of the sleeve 31 inserted into the inside of the second component 36 is sandwiched by the constraining net 20 pushed into the inside of the second component 36 and the inner circumferential surface of the second component 36. Therefore, when the portion of the sleeve 31 extending to the outside from the second component 36 is folded toward the second component 36, the sleeve 31 is prevented from coming off the inside of the second component 36. In addition, by folding a portion of the sleeve 31 extending from the second component 36 to the outside toward the second component 36, the restraint net 20 housed inside the second row component 36 is configured as a second configuration. Protruding out of the member is prevented.

  After the sleeve 31 is folded toward the second component member 36, the weight 21 is removed from the jig 70 and stored in the weight storage portion of the container 30. Finally, the lid 33 is attached to the container 30 (see FIG. 4 (d)). When the lid 33 is attached to the container 30, the tip of the tongue 33b of the lid 33 is inserted into the insertion groove 38 of the first component 35, and the hole 47 provided in the tongue 33b The projection 46 provided in the recess 40 is fitted. Finally, the O-ring 72 is attached to the cylindrical portion 35 a of the first component 35. Here, the O-ring 72 has a sealing function such as waterproofing by being sandwiched between the gripping portion 26 and the constraining net ejection portion 25 and filling the gap between the gripping portion 26 and the constraining net ejection portion 25.

  The jet circuit board 55 is attached to the main body member 50 together with the switch 56. Thereafter, the switch plate 61 is attached to the main body member 50. The switch 56 is turned off by attaching the switch plate 61 to the main body member 50.

  The fix cup 27 is attached to the body member 50. After the fix cup 27 is attached to the main body member 50, the connector 45 of the lead wire 44 provided in the gas generator 32 of the restraining net jet 25 is inserted from one end side of the main body member 50 in the axial direction. Then, the fix cup 27 is screwed and fixed to the restraint net spout 25.

  The connector 45 of the lead wire 44 provided in the gas generator 32 is fitted to the connector 58 of the lead wire 57 of the connector of the jet circuit board 55. After the lead wire 44 is folded, the cover 51 is screwed into the opening of the main body member 50. The grip cover 52 is attached to the body member 50. A grip end 53 is attached to an end of the main body member 50 opposite to the end to which the restraining net jet part is attached. Finally, the end cap 54 is attached to the grip end 53.

  The portable restraint network deployment apparatus 10 of the present invention is used in the following procedure.

  First, the end cap 54 is removed from the grip end 53. When the end cap 54 is removed, the trigger member 62 is exposed. The user holds the grip 26 with one hand and directs the restraint net spout 25 to a criminal suspect. Then, the trigger member 62 is pulled by the other hand, and the switch plate 61 is pulled out. When the switch plate 61 is pulled out, the switch 56 is turned on to supply the gas generator 32 with electricity. Thus, the gas generator 32 operates. When the gas generator 32 operates, the gas generating agent charged in the gas generator 32 burns. When the gas generating agent burns, a gas is generated. The rupture disc is fractured due to the high heat and the increase in gas pressure accompanying the generation of gas. Then, the generated gas passes through the shaping filter 43 and flows into the gas flow path. The weight 21 is ejected by the gas pressure of the gas flowing into the gas flow path, and the lid 33 is removed from the container. When the lid is removed by the ejection of the weight 21, the weight 21 ejects. The weight 21 is attached to the restraint net 20 by a string member 22. The jet of the weight 21 causes the restraint net 20 to fly. At this time, the folded portion of the sleeve 31 is pressed and opened by the restraining net 20 to be jetted. In the state where the weight 21 is stored inside the container 30, the central axes of the eight weights 21 stored in the weight storage portion are inclined at a predetermined angle with respect to the central axis of the grip portion 26, respectively. There is. Therefore, the eight ejected weights 21 fly radially about the central axis of the grip 26. Therefore, the restraint network 20 flying with the eight weights 21 flies while being deployed.

  When the switch plate 61 is pulled out, the switch button enters the guide path, so that the switch plate 61 is prevented from entering the guide path, and misuse of the used product is prevented.

  Next, the specification of the sleeve 31 will be described. The specification of the sleeve 31 includes, for example, the material of the sleeve 31, the thickness of the sleeve 31, and the like. The specifications of the sleeve 31 used in the portable restraint network deployment device are based on tests to verify the flight performance of the weight.

  As a test, in addition to a portable restraint network deployment apparatus containing restraint networks without using a sleeve (hereinafter referred to as a conventional portable restraint network deployment apparatus), a portable restraint network containing restraint networks using a sleeve A deployment device (hereinafter referred to as a portable restraint network deployment device using a sleeve) is used. Here, as a material of the sleeve, for example, three kinds of materials of nylon other than high density polyethylene (HDPE) and linear polyethylene (LLDPE) are used.

The test was conducted under the following conditions.
1) Install a portable restraint network deployment device on a platform 1.3 m high at an installation angle of 6 °.
2) Install the mannequin at a distance of 3.7 m from the fixed base.
3) Analyze the flight trajectory of the weight until the restraint network reaches the 3.7-metre mannequin when the portable restraint network deployment device is activated. The flying trajectory of the weight uses the flying trajectory of the weight rising highest among the eight weights and the flying trajectory of the weight rising lowest.

  FIG. 5 is a graph showing the flight trajectory of the weight when the verification test is performed. In FIG. 5, curves 71 and 72 indicated by solid lines connecting the symbols "o" indicate the flight trajectories of the weights in the conventional portable restraint network expansion device. Curves 73 and 74 indicated by dotted lines connecting the symbols ".DELTA." Indicate the flight trajectories of the weights in the portable restraint network deployment device using a sleeve made of HDPE. Curves 75 and 76 shown by a two-dot chain line connecting the code “□” indicate the flight trajectory of the weight in the portable type restraint network deployment device using a sleeve made of LLDPE. Lastly, curves 77 and 78 indicated by alternate long and short dash lines connecting the symbols “」 ”indicate the flight trajectories of the weights in the portable type restraint net deployment apparatus using a nylon sleeve.

  The flight trajectory of the weight in a portable restraint network deployment device using a sleeve made of HDPE or a portable restraint network deployment device using a sleeve made of LLDPE is the same as the flight trajectory of a weight in a conventional portable restraint network deployment device The flight performance of On the other hand, the flight trajectory of the weight in the portable restraint network deployment device using a nylon sleeve resulted in inferior flight performance to the flight trajectory of the weight in the conventional portable restraint network deployment device. The reason why the flight trajectory of a weight in a portable restraint network deployment device using a nylon sleeve is inferior to the flight trajectory of a weight in a portable restraint network deployment device using another sleeve is a nylon sleeve Is made of a harder material than sleeves made of HDPE or sleeves made of LLDPE. That is, in the case of nylon sleeves, the resistance of the sleeve when flying while being deployed is larger than that of the sleeve made of HDPE or the sleeve made of LLDPE, and the energy when the weight flies decreases. Be Therefore, the result that the sleeve made of HDPE or the sleeve made of LLDPE is preferable to the sleeve made of nylon is obtained.

  Next, with respect to the specifications of the sleeve, a test for verifying the flight performance of the weight will be described. In this test, a sheet having a circumferential length of 170 mm and a width of 100 mm is used as a sleeve. Further, the thickness of the sheet is four types of 0.01 mm, 0.04 mm, 0.08 mm and 0.1 mm. Moreover, the sleeve is a sleeve made of HDPE and a sleeve made of LLDPE.

  FIG. 6 is a view showing the trajectory of the weight when a sleeve made of HDPE is used. In FIG. 6, curves 81 and 82 indicated by solid lines connecting the symbols "o" indicate the flight trajectories of the weights in the conventional portable restraint network expansion device. Curves 83 and 84 indicated by dotted lines connecting the symbols ".DELTA." Indicate the flight trajectories of the weights in the portable type restraint net deployment apparatus using a sleeve with a thickness of 0.01 mm. Curves 85 and 86 indicated by alternate long and short dash lines connecting the symbol "□" indicate the flight trajectory of the weight in the portable type restraint network deployment apparatus using a sleeve with a thickness of 0.04 mm. Curves 87, 88 shown by alternate long and two short dashes lines connecting the symbol “▲” show the flight trajectories of the weights in the portable type restraint net deployment apparatus using a sleeve with a thickness of 0.08 mm. Lastly, curves 89 and 90 shown by solid lines connecting the symbols ".box-solid." Show the flight trajectory of the weight in the portable type restraint network deployment apparatus using a sleeve of 0.10 mm thickness.

  The flight trajectory of the weight in the portable restraint network deployment device using sleeves of 0.01 mm, 0.04 mm and 0.08 mm in thickness is equivalent to the flight trajectory of the weight in the conventional travel restraint network deployment device. Have. On the other hand, the flight trajectory of the weight in the portable restraint network deployment device using a 0.10 mm thick sleeve resulted in inferior flight performance to the flight trajectory of the weight in the conventional portable restraint network deployment device. The reason why the flight trajectory of the weight in a portable restraint network deployment device using a sleeve with a thickness of 0.10 mm is inferior to the flight trajectory of a weight in a portable restraint network deployment device using a sleeve with another thickness is as follows: As the thickness of the sheet itself increases, the sleeve becomes hard, and the resistance of the sleeve when it flies while expanding the restraint net increases. Therefore, the result is obtained that it is preferable to use a sleeve having a thickness of less than 0.10 mm.

  FIG. 7 is a view showing a flight trajectory of a weight when a sleeve made of LLDPE is used. In the drawing, curves 91 and 92 indicated by solid lines connecting the symbols "o" indicate the flight trajectory of the weight in the conventional portable restraint network expansion device. Curves 93 and 94 indicated by dotted lines connecting the symbols ".DELTA." Indicate the flight trajectories of the weights in the portable type restraint net deployment apparatus using a sleeve with a thickness of 0.01 mm. Curves 95 and 96 indicated by alternate long and short dash lines connecting the symbol "□" indicate the flight trajectory of the weight in the portable type restraint network deployment device using a sleeve with a thickness of 0.04 mm. Curves 97 and 98 shown by a two-dot chain line connecting the code “▲” show the flight trajectory of the weight in the portable type restraint net deployment apparatus using a sleeve with a thickness of 0.08 mm. Lastly, curves 99 and 100 indicated by solid lines connecting the symbols ".box-solid." Indicate the flight trajectory of the weight in the portable type restraint net deployment apparatus using a 0.10 mm thick sleeve.

  When LLDPE sleeves are used, the flight trajectory of the weight in the portable restraint network deployment device using sleeves with a thickness of 0.01 mm, 0.04 mm and 0.08 mm is the same as in the case of using HDPE sleeves. Each has a flight performance equivalent to the flight trajectory of a weight in a conventional portable restraint network deployment device. On the other hand, the flight trajectory of the weight in the portable restraint network deployment device using a 0.10 mm thick sleeve resulted in inferior flight performance to the flight trajectory of the weight in the conventional portable restraint network deployment device. The reason why the flight trajectory of the weight in a portable restraint network deployment device using a sleeve with a thickness of 0.10 mm is inferior to the flight trajectory of a weight in a portable restraint network deployment device using a sleeve with another thickness is as follows: As the thickness of the sheet itself increases, the sleeve becomes hard, and the resistance of the sleeve when it flies while expanding the restraint net increases. Therefore, even in the case of using a sleeve made of LLDPE, the same result as in the case of using a sleeve made of HDPE is obtained that it is preferable to use a sleeve having a thickness of less than 0.10 mm.

  Therefore, when using a sleeve when storing a restraint net in the restraint net jet part of a portable restraint net deployment device, it was obtained that it is preferable to use a sheet of HDPE or LLDPE as a material of the sleeve. In addition, as a thickness of a sheet used for the sleeve, it was found that it is preferable to use a sheet of 0.08 mm or less.

  In the present embodiment, a test is conducted to measure the flight performance of a weight in a portable restraint net deployment apparatus in which a restraint net is housed using sleeves made of HDPE, LLDPE and nylon. However, in addition to using HDPE and LLDPE as the material of the sleeve, it is also possible to use a lapping film such as thin paper, polyvinyl chloride or polyvinylidene chloride.

  In the present embodiment, a sleeve 31 obtained by processing a belt-like sheet into a cylindrical shape is used to prevent the restraint network 20 from coming out of the opening of the second component 36. However, the shape of the sleeve is not limited to the cylindrical shape. That is, if the restraint network 20 is prevented from coming out of the opening of the second component 36 at the time of manufacture of the portable restraint network deployment device 10, and the restraint network 20 is deployed and can fly when the restraint network 20 spouts. Good. As one example, as shown in FIG. 8, it may be a bag-like sleeve 105 which is open at one end. Here, among the portable type restraint network deployment devices, there are also portable type restraint network deployment devices in which a restraint network and a container are connected by a pulling cord. Therefore, in the case of using the bag-shaped sleeve 105 in a portable restraint network expansion device for connecting the restraint net and the container by pulling the string, the insertion hole 105a through which the pulling string is inserted may be provided.

  Further, as shown in the present embodiment, in the case of using the sleeve 31 formed by processing a belt-like sheet into a cylindrical shape, the second configuration may be used when the sleeve 31 protruding from the second component 36 is folded depending on the length. It is also contemplated to cover only the outer peripheral portion of the opening portion of the member 36. Even in such a case, since the vicinity of the outer peripheral portion of the second component 36 is covered by the folded sleeve, when attaching the lid 33 to the container 35, a part of the restraint net 20 is the lid 33 and the container It is prevented from coming out between 30 and. However, if the area shielded by the folded back sleeve 31 is small, there is a risk that the folded back sleeve 31 may be returned to the original state by the restraint net 20 which tends to protrude from the opening of the second component 36 . As a result, when the lid 33 is attached, the covering by the sleeve 31 is released, and a part of the restraint net 20 may come out of the container 30. In order to eliminate such an event, it is also possible to place the disc-like sheet 106 on the top of the folded sleeve 31 and attach the lid 33 to the container 30.

  In this embodiment, a sleeve formed by processing a band-shaped sheet into a cylindrical shape is provided separately from the second component, but the sleeve formed by processing a band-shaped sheet into a cylinder and the second component are integrally formed. You may
