Description

  The present invention relates to a catcher that captures a suspicious person or the like, and more particularly, to an open / close catcher that opens and closes only the tip of a bifurcated catch part.

Conventionally, so-called piercing is known as an instrument for capturing a target person such as a thief or a suspicious person. The piercing is a U-shaped fitting attached to the tip of a long handle, and the U-shaped portion is pressed against the person to be captured to seal its movement.
In recent years, especially with the background of the increasing number of illegal intruders in elementary schools and convenience stores, piercing has attracted attention, and various more functional piercings have been developed.
For example, in the open / close trap shown in Patent Document 1 shown in FIG. 9, the slide shaft 11 slides in the proximal direction within the cylindrical body 1 by pressing the tip 11 a of the slide shaft 11 against the person A to be captured. The two arms 21 are closed according to the sliding width, and the sliding of the slide shaft 11 in the distal direction is controlled by the stopper means 12.
10 includes a bifurcated member 11 and capture members 12 and 13 at the front end of the bar member 2. When the criminal's neck and limbs are brought into contact with the capture members 12 and 13, the capture members 12 and 13 rotate inward and the neck and limbs are taken into the bifurcated member 11.
11 includes a gate-type movable lever 3 and a capture lever 2, and when the movable lever 3 is pressed against a person to be captured, the movable lever 3 rotates backward. The capture lever 2 that rotates integrally with the movable lever 3 is closed so as to wrap the person to be captured, and thereafter, the restraint state is maintained by the reverse rotation prevention metal fitting 5.
Further, in the catching device described in Patent Document 4 shown in FIG. 12, the arms 3 and 4 having elasticity have the first folded sides 5 and 6 and the second folded sides 7 and 8, and the anti-slip means 9 is further provided. Therefore, once the person to be captured is taken into the catching tool body 2, the structure is difficult to escape thereafter.

However, the above-described conventional technique has the following problems.
That is, in the technique described in Patent Document 1, it is necessary to press the slide shaft tip 11a against the capture target person A. However, in a situation where the capture target person is moving around in resistance, the capture target person is placed inside the arm. Since it takes a long time, it is not easy to press the tip 11a against the person to be captured. In particular, in a situation where the capture subject has gripped the cylinder 1 by hand, there is a gap between the capture subject and the tip portion 11a, so it is almost impossible to press the tip portion 11a against the capture subject. become.
In the technique described in Patent Document 2, the opening at the tip of the bifurcated member 11 is almost closed by the capture members 12 and 13 in a normal state. That is, when the piercing is applied to the capture target person in a state of facing the capture target person, the capture members 12 and 13 are in a position extending in the horizontal direction when viewed from the capture target person. 13 can be easily grasped by hand. And once grasped by hand, it becomes extremely difficult to restrain the person to be captured in the bifurcated member 11 after that.
Also, in the technique described in Patent Document 3, as in the case of Patent Document 2, when the pierced crotch is attached to the capture target person in a state of facing the capture target person, the movable lever 3 extends in the horizontal direction when viewed from the capture target person. Since it exists in a position, the capture subject can grasp the movable lever 3 easily.
Moreover, in the technique described in Patent Document 4, it is difficult to capture unless the captured object is accurately placed in the axial direction so that the person to be captured is positioned at the center of the left and right arms 3 and 4. In other words, if the person to be captured is present at a position close to the right arm 3 when the catching tool is added, the amount of elastic deformation of the right arm 3 and the amount of elastic deformation of the left arm 4 are different. It becomes difficult for the subject to get caught on one of the arms, and to be restrained inside the catching tool body.

  In view of the above problems, an object of the present invention is to provide an open / close type catcher that can be reliably restrained even in a situation where a person to be captured is moving around.

An open / close type trap of the present invention includes a bifurcated capture part, a handle that supports the capture part, a bent part located at the tip of the capture part, an operation part that operates an opening / closing operation of the bent part, And a lock mechanism for maintaining the closed state.
In addition, when the bent portion is in an open state, the interval between the two axes of the bent portion is widened toward the tip.

The open / close trap of the present invention opens and closes only the bent portion located at the tip of the bifurcated trap. That is, by setting the bent portion in an open state, it is possible to reduce as much as possible the portion that is easily grasped by the capture target person under the situation of facing the capture target person.
Moreover, once the capture target person is captured in the capture unit, the capture target person can be restrained by the capture unit by operating the operation unit to close the bent portion.
Further, since the closed state of the bent portion can be maintained by the lock mechanism, it is difficult for the capture target person to expand the bent portion to the open state by himself / herself, and the capture target person can be surely restrained even when the capture target is moving around.
Moreover, even if the capture target person is holding the handle or the capture part by hand, it can be easily restrained by closing the bent part from the back (back side) of the capture target person.
In addition, by making the interval between the two axes of the bent portion widen toward the tip in the open state, it is possible to make it easier for the person to be captured to enter the capture portion.

It is a figure which shows the stab-type open / close trap of patent document 3. It is a figure which shows the catching tool of patent document 4.

As shown in FIG. 1, the open / close type trap 10 of the present invention (hereinafter, also simply referred to as “capture device”) is schematically composed of a trap part 20, a handle 30, a bent part 40, an operation part 50, and a lock mechanism 60. Yes.
As shown in FIG. 2, the capture part 20 is a bifurcated member that is integrated with the bent part 40 and restrains the person to be captured inside, and has a U-shape in plan view by curving an iron hollow pipe. It is integrally formed to be. Note that the handle 30 and the bent portion 40 are similarly formed of hollow pipes.
The handle 30 is a rod-like member that is joined to the rear end of the capture unit 20 and supports the capture unit 20. A first handle 31 and a second handle 32 are attached to the central portion of the handle 30 to facilitate handling of the trap 10. The length of the handle 30 is preferably about 1.6 meters. This is because if the distance is 1.5 meters or less, the captured target person may touch the user of the trap 10 and cause harm by bending his body and reaching out.
The bent portion 40 is a member located at the tip of the capture unit 20, and is bent inward as indicated by an arrow in FIG. 3 by operating the operation unit 50. Restrained.

The connecting portion between the capture portion 20 and the bent portion 40 will be described. As shown in FIG. 4, slits 21 are formed on the left and right sides of the tip of the capture portion 20 (only the right slit 21 is shown in FIG. 4). ing). Similarly, slits 41 are formed on both the left and right sides of the rear end of the bent portion 40 (only the right slit 41 is shown in FIG. 4). The front and rear ends of the thin plate-like connecting plate 70 are pivotally supported by pins 71 and 72, respectively. Accordingly, the bent portion 40 has a structure that can rotate in the left-right direction with respect to the capturing portion 20.
Further, the front end of the capturing part 20 and the rear end of the bent part 40 are inserted into the coil spring 80. The coil spring 80 itself is fixed to the surface of the bent portion 40 and the capturing portion 20 at both front and rear ends.
The coil spring 80 is designed so that it is in a straight line state when no load is applied, that is, the central axis is a straight line. Moreover, since the capture part 20 and the bending part 40 are connected via the connection plate 70, the axial direction of the bending part 40 is set to the axis direction of the capture part 20 in a state where no force is applied to the bending part 40 (open state). A force that substantially matches the direction acts on the bent portion 40 from the coil spring 80. Thereby, the capture part 20 and the bent part 40 are substantially U-shaped when viewed in plan as a whole, and the axes of the left and right bent parts 40 are substantially parallel when viewed in plan.

As shown in FIGS. 5 and 6, the operation portion 50 is provided at the rear end portion of the handle 30 in order to operate the opening / closing operation of the bending portion 40, and the frame 51 and the inside of the frame 51 are moved in the front-rear direction. And a wire 53 for opening and closing the bent portion 40 by the operation of the grip portion 52.
The frame 51 is formed by joining thin plates on both the front and back sides and the left and right sides, and has an opening 54 in the center.
The grip portion 52 is a member made of a thin plate having a square shape in plan view, and the left and right sides of the grip portion 52 are fitted in the frame body 51 so that the grip portion 52 can slide in the front-rear direction in the opening 54 of the frame body 51.

As shown in FIG. 6, one end portion of the wire 53 is connected to the front portion of the grip portion 52. The wire 53 passes through the inside of the handle 30 made of a hollow pipe through the first opening 55 formed in the front portion of the frame 51 from the grip portion 52, and the second opening 56 formed in the vicinity of the upper portion of the handle 30 (see FIG. 3) and is exposed to the outside and branches to the left and right, passes through a plurality of rings 57 attached to the capture unit 20, and the other end is connected to the inside of the tip of the bent portion 40.
5 and 7 show a state in which the protective cover 58 is wound around the front portion of the grip portion 52, and FIG. 6 shows a state in which the protective cover 58 is removed. In FIG. 6, the illustration of the handle 30 and the lock mechanism 60 is omitted.

As described above, in the normal state (open state), the capture part 20 and the bent part 40 are substantially U-shaped when viewed in plan as a whole, and when the grip part 52 is grasped and moved to the rear of the frame 51. The wire 53 connected to the grip part 52 is pulled backward. Since the wire 53 is connected to the tip of the bent portion 40 and the rear end of the bent portion 40 is pivotally supported by the pin 71, the bent portion 40 pulled backward by the wire 53 resists the force of the coil spring 80. And it rotates back centering on the place pivotally supported by the pin 71, and stops in a state (closed state) rotated to a position substantially orthogonal to the axis of the handle 30.
In the closed state, the capture part 20 and the bent part 40 are substantially D-shaped when viewed as a whole. In the closed state, the coil spring 80 is bent at a substantially right angle, and the state in which the restoring force of the coil spring 80 acts on the bent portion 40 is maintained.
As shown in FIG. 5, the lock mechanism 60 is a substantially L-shaped thin plate member when viewed from the side. One end portion of the lock mechanism 60 is connected to the front portion of the frame body 51 with a hinge 61, and is rotatable in the front-rear direction around this portion.
At the other end of the lock mechanism 60, an abutting portion 62 that is bent substantially at a right angle is formed. When the grip portion 52 is grasped and the bent portion 40 is closed, the restoring force of the coil spring 80 acts on the bent portion 40 as described above. Therefore, the restoring force is applied via the wire 53 to the grip portion 52. Acts to force the grip 52 to return to the front. Therefore, as shown in FIG. 7, the locking mechanism 60 is rotated rearward, and the abutment portion 62 is abutted against the front portion of the grip portion 52, so that the forward movement of the grip portion 52 is limited, and the bent portion 40. The closed state can be maintained.

In the above embodiment, the axes of the two left and right bent portions 40 are substantially parallel in the open state. However, the present invention is not limited to this, and the two axes of the bent portion 40 are not limited to this. The interval may be increased toward the tip. In this case, it is preferable to use a torsion spring (not shown) and the coil spring 80 in combination. Specifically, with the torsion spring itself fixed to the connecting plate 70, one of the two arms of the torsion spring is fixed in the bent portion 40 and the other is fixed in the capturing portion 20. By making the angle (arm angle) formed by the two arms larger than 180 degrees, the interval between the two axes of the bent portion 40 can be expanded toward the tip. This makes it easy to capture the person to be captured in the capture unit 20.
In the above embodiment, the wire 53 is exposed to the outside through the second opening 56 formed in the vicinity of the upper portion of the handle 30. However, the present invention is not limited to this. The structure may be such that it is branched and is exposed to the outside in the vicinity of the front end of the capture unit 20.

  It relates to an open / close type trap that captures suspicious persons, etc., and has industrial applicability.
