Description

  The present invention relates to a piercing crotch that presses against a torso, a foot, or the like to be captured to prevent resistance or escape of the capture target, surrounds the torso, a leg, or the like to be captured and reliably captures or restrains. The capture target is a person or an animal, especially a criminal who possesses a weapon or a ferocious animal.

  A conventional piercing crotch is a crime prevention device in which a bifurcated square rod is attached to the tip of a long rod, and the capture target is pushed into the wall or the floor at the bifurcated portion and held.

  However, if the user is a woman, the elderly, a child, etc., and the capture target is ferocious, and there is a difference in power far from the user, it will be seized, captured, and restrained using conventional piercing crotch It is almost impossible.

  Therefore, a piercing crotch 1F having a function of locking with an annular restraining portion is disclosed in Patent Document 1 (FIG. 18 of Patent Document 1).

  The pierced crotch 1F described in Patent Document 1 is provided with pin-supported arc-shaped restraining members 4 and 5 at both ends of a bifurcated curved pressing member 3 provided at the tip of the handle 1 at a substantially central position. The arcuate restraining members 4 and 5 are configured to be openable and closable around the pin support portions 30a and 30a. Reference numeral 30b denotes a spring body for maintaining the restraining members 4 and 5 in a predetermined open state by spring biasing, thereby preventing the restraining members 4 and 5 from being brazed.

  That is, the piercing crotch 1F according to the fifth embodiment (as shown in FIG. 19 of Patent Document 1) is a pin in the restraining members 4 and 5 when the body of the villain DM is strongly pressed toward the pressing portion 3. The violent crime DM contacts the inner base end portion 40 of the supported position and is pushed in the direction of the pressing portion 3, and at the same time, by the lever principle, the portion outside the pin supported position in the restraining members 4 and 5 Is formed in a structure that surrounds the body of the violent crime DM and that the front end portions 4b, 5b of the left and right restraining members 4, 5 are connected and locked. This connection structure is performed by locking similar to the piercing crotch 1A of the first embodiment of Patent Document 1.

  The locking of the pierced crotch 1A of the first embodiment of Patent Document 1 shows a structure in which the distal end portions of the left and right restraining members 4 and 5 can be joined and fixed as described in paragraph 0063. In this case, the distal end portion 4b of one restraining member 4 enters and locks into a lock portion 5c provided integrally with the distal end portion 5b of the other restraining member 5. Note that when the key K is inserted into the keyhole 5d of the lock portion 5c and operated, the lock is unlocked.

  In addition, as described in paragraph 0088, the connecting and fixing structure of the left and right restraining members 4 and 5 has been described with a locking structure, but this is not a locking structure and is not shown in the figure. For example, a wedge-shaped protrusion is formed on the outer peripheral surface of the tip of one restraining member, an opening into which the tip of the one restraining member projects is formed at the tip of the other restraining member, and the inner peripheral wall of this opening is formed. A projection structure that engages with the projection may be formed, and when the tip of the one restraining member enters the opening at the tip of the other restraining member, the projections may be engaged with each other to prevent the projection from coming off. .

Further, according to paragraph 0089, according to this connection structure, once engaged and connected, it cannot be separated, so that this situation cannot be prevented, the inside of the tip of the other restraining member It is described that it is desirable to make the structure a two-part structure so that it can be detached when the screw is removed.

  However, in the piercing crotch 1F described in Patent Document 1, the opening mechanism and the locking structure of the left and right restraining members 4 and 5 are not specific and cannot be implemented.

  In addition, since the annular restraining portion has a fixed size, it can be used only for a capture target of a fixed size. If the capture target is larger than the annular restraint, it cannot be captured and locked in an annular shape. Further, if the capture target is narrower than the annular restraining portion, even if it is captured and locked by the annular restraining portion at one end, it will slip through the annular restraining portion.

  Furthermore, when not in use, the left and right restraining members 4 and 5 are always open, and the storage location is limited.

  Therefore, the present invention is capable of reliably capturing and restraining and locking without limiting the size of the object to be captured and its size. Further, when not in use, the restraining portion can be closed and stored and stored in a compact manner.

In addition, a recess 4j cut out so that the left turning arm 5 can be opened outward is provided on the outer side of the front end of the pressing member 4.

  FIG. 10 is a plan view seen from the direction of the one-dot chain line arrow A ′ in FIG. 9. With reference to FIG. 10, the attachment method to the left rotation arm 5 of the rotation arm 8 is demonstrated. The rotation support portion 5a has a hole 8h that is connected to and fixed to a wire 5f that constitutes one end of the tension portion 8i, a columnar rotation shaft 8f that passes through a predetermined position of the left rotation arm 5, and a left and right rotation plate 8b. , 8c and the outer side of the left turning arm 5, left and right rings 8g, 8g for assisting rotation, and left and right fasteners 8e, 8e such as screws for rotatably locking the rotating shaft 8f. Become.

  In addition, the tension | tensile_strength part 8i is the fixing tool 5g, and the other end is fixed to the long hole 5c and a target position. Further, the holding claw 5b is attached so as to be pivotable back and forth at the position of the fastener 5d.

  FIG. 11 is a cross-sectional view showing the operation of the rotating arm. The rotating arm 8 is indicated by a dotted line. FIG. 11A shows the state of the rotary arm 8 before locking, and FIG. 11B shows the start of rotation of the rotary arm 8 at the time of locking.

  The tension portion 8i inside the left turning arm 5 is composed of a wire 5f having one end connected to the rotating shaft 8f and an elastic body such as a tension coil spring 5i connected to the other end of the wire 5f. The other end of the spring 5i is fixed with a fixing tool 5g such as a bolt or a nut. In order to connect the wire 5f and the spring 5i, the end of the wire 5f is bound by a band 5h or the like, and the spring 5i is hooked.

  As shown in FIG. 11A, the end portion of the wire 5f is wound around the rotary shaft 8f before locking. In this state, the holding claw 5b engages the roller 8a of the rotating arm 8. In order to allow the holding claw 5b to turn back and forth, and to attach the tension portion 8i to the inside of the left turning arm 5, a long hole 5c is provided in the left turning arm 5.

  In addition, as shown in FIG. 11B, in conjunction with the operation of the locking button 14c, when the wire 5n is pulled in the direction of the arrow and the holding claw 5b releases the locking of the roller 8a, the spring 5i contracts, The wire 5f is pulled, and the rotation shaft 8f further rotates. Along with this, the rotation arm 8 fixed to the rotation shaft 8f rotates, and the roller 8a collides with the elevating plate 7e of the lock body 7. , 6 can be connected, and the restraining portion 3 can be locked in an annular shape. In addition, the rotating arm 8 shown with the dashed-dotted line represents the position at the time of locking.

  Here, the holding portion 14o that holds the rotating arm 8 constituting the rotating arm release device 14 will be described. The holding portion 14o is attached to the case 5j fixed to the left rotation arm 5 with a fastener 5l and the like, and is rotatably attached to the case 5j. The roller 8a of the rotating arm 8 is locked by a spring bias such as the spring 5o. The holding claw 5b is a substantially L-shaped holding claw having a hook-like tip.

  The holding claw 5b is inserted into a shaft 5k through which the case 5j is inserted, and is attached to be rotatable. One end of the torsion coil spring 5o inserted through the shaft 5k is in contact with the case 5j, and the other end is locked in a hole 5p provided in the holding claw 5b. Thereby, the spring bias of the spring 5o is always added to the position which latches the roller 8a.

  Further, a wire 5n is connected to a hole 5m formed in a substantially upper end of the holding claw 5b so as to be interlocked with the operation of the locking button 14c. Thus, when the wire 5n is pulled, the holding claw 5b rotates about the shaft 5k and opens the roller 8a. In order to ensure that the tension of the wire 5n acts, the wire 5n is preferably passed through the hole 5q provided in the bottom of the side surface of the case 5j.

  In this way, the rotating arm 8 is rotated by the tension of the spring 5i. The rotating method of the rotating arm 8 shown here is an example, and any mechanism can be adopted as long as the rotating arm 8 starts rotating in response to the collision of the capture target 12. Good.

  FIG. 12 is a cross-sectional view of the rotary arm release device. Next, the rotary arm release device 14 will be described. The rotary arm release device 14 connects the holding unit 14o that holds the rotary arm 8 before locking, the switch unit 14n that generates a signal that triggers the release of the rotary arm 8, and the switch unit 14n and the holding unit 14o.

  FIG. 12A is a cross-sectional view of the distal end portion of the left rotating arm 5 and the holding portion 14o. The wire 5n before locking is indicated by a dotted line, and the wire 5n at the start of locking is indicated by a one-dot chain line. FIG. 12B is a cross-sectional view of the distal end portion of the left rotating arm 5 and the switch portion 14n when the restraint portion 3 before capturing the capture target 12 is open. FIG. 12 (C) shows that when the capture target 12 is captured, the end of the left rotating arm 5 and the switch when the lock button 14c is pushed in conjunction with the capture target colliding with the pressing member 4. It is sectional drawing of the part 14n.

  It should be noted that the state when the restraining portion 3 is open before capturing the capture target 12 is a combination of the holding claws 5b shown by the solid line in FIG. 12A and FIG. 12B.

  The holding portion 14o is as described above, and the switch portion 14n is attached to the frame body 14e installed inside the left turning arm 5 and the frame body 14e so as to be rotatable, and by a spring bias such as a spring 14h, The rotating body 14a, which is an elliptical disk having a protrusion 14b that rotatably connects the locking button 14c protruding to the outside of the left rotating arm 5 (inside the pressing member 4), and the locking button 14c operates. A hole 5u is provided as a guide for the rotation, and is drilled in the left turning arm 5, and is fixed to the left turning arm 5 with a fastener 5t such as a screw so as to cover the hole 5r which is a protruding hole of the locking button 14c.

  The rotating body 14a is inserted into a shaft 14d through which the frame body 14e is inserted, and is attached to be rotatable. Also, one end of the torsion coil spring 14h inserted through the shaft 14d is inserted into a hole 14j provided in the side plate of the frame body 14e, and the other end is engaged with a recess 14i provided in the rotating body 14a. Thereby, when the restraining part 3 is in the open state, the spring bias of the spring 14 h is applied so that the locking button 14 c always protrudes from the left rotating arm 5 toward the pressing member 4.

  The adjusting portion 14p is an adjusting screw that connects the fixing member 14k (here, a U-shape) fixed to the end portion of the left rotating arm 5 with a fastener 141 such as a screw, and the fixing member 14k and the frame body 14e. 14m. The tension of the wire 5n can be adjusted by tightening or loosening the adjusting screw 14m. By providing this adjustment part 14p, it becomes unnecessary to pay great attention to the installation position of the switch part 14n.

  Further, the wire 5n is connected to a hole 14g provided at a position where the wire 5n can be pulled on the rotating body 14a so as to transmit the operation of the locking button 14c to the holding claw 5b. Thus, as shown in FIG. 12C, when the capture target is pressed against the pressing member 4, the left and right pivot arms 5 and 6 collide with the left and right storage portions 4c and 4d of the pressing member 4, at the same time. The locking button 14c is pushed into the left rotating arm 5, the rotating body 14a rotates about the shaft 14d, and the wire 5n is pulled.

  As a result, the holding claw 5b rotates backward about the shaft 5k at the position of the holding claw 5b shown by the alternate long and short dash line in FIG. 12A, the roller 8a is opened, the rotary arm 8 rotates, and the roller 8a Collides with the elevating plate 7e of the lock body 7 and can be locked. In order to ensure that the tension of the wire 5n acts, the wire 5n is preferably passed through the hole 14f provided at the side surface position of the frame body 14e so that the distance from the hole 14g is maximized.

  In the open / close piercing 1 thus constructed, the rotating arm release device 14 is activated simultaneously with the capture, the rotating arm 8 is rotated, the lock 11 is locked, and the left and right rotating arms 5, 4 are securely connected by the rotating arm 8. It is superior to the conventional piercing crotch in that it can be firmly connected and can reliably capture the capture object 12a.

  FIG. 13 is a plan view of a second embodiment of the open / close piercing according to the present invention. The opening / closing piercing crotch 1a has a cylindrical long handle 2a to be grasped by a hand, a U-shaped pressing member 16 attached to the tip of the long handle 2a, and a curvedly attached to both ends of the pressing member 16 so as to be rotatable.

And a lever 15c that is detachably attached to the handle 15b.

  Therefore, the long handle 2a has a cylindrical shape because the piercing crotch 15 is inserted into the inside. Moreover, the long hole 2b is provided so that the lever 15c for pushing the small crotch 15 into the capture object 12a can move back and forth.

  In addition, since the intensity | strength of the connection part of the long handle 2a and the restraint part 3a increases by making the front-end | tip of the long handle 2a into Y shape like FIG. 13, it is more desirable. In addition, as long as the strength of the connecting portion between the long handle 2a and the restraining portion 3a can be maintained, the tip of the long handle 2a may be formed in a rod shape, and the long handle 2a may be directly connected to the restraining portion 3a.

  The restraining portion 3a is inserted with the restraining portion 3 of the first embodiment except that the pushing member 16 having a hole 16a formed on the extension of the long handle 2a of the pushing member 4 is attached in order to insert the stabbing crotch 15. It is the same. In addition, the left and right opening holders 9 and 10, the lock 11, the capture target 12 a, and the rotating arm release device 14 are the same as those in the first embodiment.

  FIG. 14 is a partially broken plan view of the restraint portion of Example 2 in the closed state when captured and restrained.

At the same time, the locking button 14c protruding to the outside of the left rotating arm 5 is pushed in.

  At this time, the left and right opening holders 9 and 10 are crushed between the left and right turning arms 5 and 6 and the pressing member 16. In conjunction with the pressing of the locking button 14c, the holding claw 5b holding the rotating arm 8 operates (rotates) to open the rotating arm 8.

  Thereafter, when the capturer presses the lever 15c quickly and strongly toward the capture target 12a, the handle 15b of the stabbing crotch 15 slides inside the long handle 2a, and the pushing portion 15a is pressed against the capture target 12a. The capture target 12a is sandwiched between the pushing portion 15a and the left and right turning arms 5 and 6. As a result, even the thin capture target 12a can be reliably captured.

  Since the opening / closing piercing crotch 1a thus formed can be tightly restrained with the piercing crotch 15 instantaneously even when the capture target 12a is slender or restrains a thin part such as an arm or a leg, This is superior to the open / close piercing crotch 1 of the first embodiment in that the capture target 12a can be reliably captured without being limited by the size of the capture target.

  FIG. 15 is a plan view of a third embodiment of an open / close type piercing according to the present invention.

  The gear device 21 has a ring 21j sandwiched between the long holes 18f of the left and right covers 18b and 18c, a shaft 21g that is movably attached by a fastener 21h such as a screw, and the shaft 21g. The gear device 21 is inserted into the long hole 2d of the long handle 2c. A gear 21a that is indented into a part of the long handle 2c, meshes with a groove 17c provided in the small crotch 17 and has a hole 21b that receives a fitting member 23 described later in a circular shape, and one surface of the gear 21a A ring 21c made of elastic rubber, silicon, etc. arranged so as to contact the ring, and a ring 21d, ring 21e arranged so as to come into contact with the left and right of the gear 21a and the ring 21c, and the handle 18a, It consists of about three rings 21f.

  With the ring 21c, the rings 21d, 21e and the ring 21f arranged between the handle 18a and the gear 21a can be arranged without any gap, and when the stopper 22 is engaged with the gear 21a, the handle 18a is moved forward. When the fitting member 23 is engaged with the gear 21a, the gear 21a is also rotated by pulling the handle 18a backward, and the piercing crotch 17 can be sent forward.

  In addition, as shown in FIG. 19, when the diameter of the small thigh 17 is smaller than the inner diameter of the long handle 2 c and the inside of the long handle 2 c is violated, the small thigh 17 is not formed in the long handle 2 c so as to sandwich the pushing device 18. It is necessary to fix and provide the guides 20 and 20 having the holes 20a having the same shape as the long handle 2c provided so as to penetrate the fasteners 20b.

  This is because the gear 21a and the groove 17c of the stabbing crotch 17 are separated from each other and are not bitten, the stabbing crotch 17 is pushed back, and the capture target 12a escapes from the annular restraining portion 3a. By providing the guide 20, the gear 21 a and the groove 17 c of the stabbing crotch 17 are reliably engaged with each other, and the stabbing crotch 17 is not pushed back.

  The push-in release device 24 passes through a locking portion 24d and a locking portion 24e provided on the inner surface of the left cover 18b, is located above the shaft 21g and outside the handle 18a (tip), and is in a rod shape that contacts the ring 21f. The upper left holding spring 24a and the locking portion 24d and locking portion 24e provided on the inner surface of the right cover 18c are passed through, positioned above the shaft 21g and outside the handle 18a (tip), and in contact with the ring 21f. It consists of a rod-shaped upper right holding spring 24b.

  Normally, the spring bias of the left and right upper holding springs 24a and 24b acts in a downward direction on the ring 21f, that is, in a direction in which the gear 21a meshes with the stabbing crotch 17, and the stabbing crotch 17 is captured by the gear device 21 and the handle 18a. It is possible to push towards 12a.

  When releasing the push of the capture target 12a by the stabbing crotch 17, the handle 18a is grasped by hand, lifted upward, and the gear device 21 is moved upward to release the meshing of the stabbing crotch 17 and the gear 21a. It is possible to push back the piercing crotch 17.

  The lower holding spring 24c passes through a locking portion 24f provided inside the left and right covers 18b, 18c, is positioned below the shaft 21g and outside the handle 18a (tip), and contacts the ring 21f. It is a letter-shaped spring. Due to the spring bias of the lower holding spring 24c, the handle 18a is always held in a state slightly lifted from the connecting portion of the left and right covers 18b, 18c.

  By holding the handle 18a in a state in which the handle 18a is always returned, when the handle 18a and the long handle 2c are simultaneously grasped by the hand in the restraining part opening device 34 to be described later, the stabbing crotch 17e is instantaneously fed slightly in the distal direction, The restraining portion 3b is released. Thereby, opening of a restraint part is easy and reliable, and the capture timing of the capture target 12a is not missed.

  FIG. 20 is an enlarged cross-sectional view of the stopper mounting portion. The stopper 22 includes a shaft 22c fixed to the left and right covers 18b and 18c, a stop plate 22a rotatably attached to the shaft 22c, and a spring 22b such as a torsion coil spring inserted through the shaft 22c. The other end is in contact with the gear 21a and is locked by a connecting portion in which the left and right covers 18b and 18c are connected by a fastener 18e, so that the stop plate 22a is always biased in the direction of the gear 21a.

  FIG. 20A shows a state where the stopper 22 prevents the gear 21a from rotating in the direction in which the piercing crotch 17 is pushed back. FIG. 20B shows a state in which the stopper 22 does not act on the rotation of the gear 21a when the small thigh 17 is pushed into the capture target 12a.

  As shown in FIG. 20A, normally, the spring 22b is biased so that the stop plate 22a is engaged with the teeth 21i of the gear 21a, and the gear 21a is rotated in the direction in which the barb 17 is pushed back (downward in the drawing). Can not. On the other hand, as shown in FIG. 20B, when the gear 21a rotates in the direction of the arrow A ′, that is, when the piercing crotch 17 is pushed in the direction of the capture target 12a, the stop plate 22a is moved to the arrow B ′ by the teeth 21i. The stopper 22 does not act on the rotation of the gear 21a. As shown in the figure, when the stop plate 22a is bent, it is more reliably engaged with the teeth 21i.

  FIG. 21 is an explanatory diagram of the fitting member. The fitting member 23 is fixed to the left and right fixing plates 23a and 23a attached to the handle 18a (slightly oblique from the direction perpendicular to the handle 18a), and a fastener 23e such as a screw to the left and right fixing plates 23a and 23a. The shaft 23b includes a claw 23c rotatably attached to the shaft 23b, and a spring 23d that presses the claw 23c against a hole 21b provided in the gear 21a.

  FIG. 21A is a front view of the fitting member 23 attached to the handle 18a when viewed from the gear 21a direction. FIG. 21B is a side view of the fitting member 23 attached to the handle 18a. FIG. 21C is a side cross-sectional view of the fitting member 23 showing a state in which the claw 23c is biting into the gear 21a when the handle 18a is operated (front side) and the stabbing crotch 17 is pushed into the capture target 12a. is there. FIG. 21D is a side cross-sectional view showing the operation of the fitting member 23 when the handle 18a is moved in the direction of the restraining portion 3a.

  The tip 23f of the claw 23c has a surface in contact with the hole 21b and a gentle slope that pushes the claw 23c out of the hole 21b at the edge of the hole 21b. When the distal end portion 23f is fitted in the hole 21b of the gear 21a and the handle 18a is pulled forward, the gear 21a is rotated forward together with the handle 18a. As a result, the small thigh 17 is pushed out in the direction of the restraining portion 3a.

  One end of the spring 23d is locked to the edge of the handle 18a, passes through the gear 21a side of the shaft 23b from the opposite side of the handle 18a surface to which the fitting member 23 is attached, and the tip passes through the back of the claw 23c. It is U-shaped, and the tip 23f of the claw 23c is always pressed against the gear 21a by spring bias.

  FIG. 22 is a sectional view for explaining the pushing means. As shown in FIG. 22, when the handle 18a positioned in the direction of the restraining portion 3 is rotated in the direction of the arrow A ', the claw 23c of the fitting member 23 is depressed into the hole 21b of the gear 21a by the spring bias. Therefore, as the handle 18a rotates, the gear 21a rotates in the direction of arrow A ′ together with the handle 18a.

  At this time, the teeth 21i of the gear 21a push up the stop plate 22a of the stopper 22 in the direction of the arrow B ′ along with the rotation of the gear 21a, and the stopper 22 stops the rotation of the gear 21a in the direction of the arrow A ′. Never do.

  When the gear 21a rotates, at the same time, the teeth 21i of the gear 21a feed the piercing crotch 17 toward the restraining portion 3a while meshing with the groove 17c of the piercing crotch 17. On the other hand, even if the capture target 12a tries to push back the piercing crotch 17, the stop plate 22a of the stopper 22 prevents the gear 21a from rotating in the direction opposite to A ′, and the piercing crotch 17 that has been fed out is pushed. Never returned.
