Description

Fork type body binding equipment capable of opening and closing

Technical Field

The invention relates to a fork type openable body constraint device which can protect the body from being attacked by criminals, gangsters and the like approaching life and body, and can constrain the feet, hands and the like of the criminals and the like to prevent the body from freely moving, thereby preventing the criminals and the like from resisting and escaping.

Background

Conventionally, forks have been used as a defensive apparatus or a catching apparatus for protecting a body from a gangster and catching the gangster. In addition, police use handcuffs to catch criminals when they are apprehended. The fork is used from the river family age, and is a defensive apparatus, namely, a bent two-fork-shaped pressing component is arranged at the front end of a long handle, and gangsters and the like which violently resist are pressed on a wall and the ground by the two-fork part to catch the gangsters and the like.

Examples of such a fork include a fork catching tool described in japanese patent laid-open nos. 2000-230800 and a fork described in japanese patent laid-open No. 2003-254697. The "fork-shaped catching prop" described in the above-mentioned publication can move the distal end portion of the bifurcated pressing portion to approach each other to form a closed state, and the body cannot move freely.

The "fork catch prop" described in japanese patent application laid-open No. 2000-230800 has a slide body provided at the center of a bifurcated pressing portion that is left and right apart, and the slide body protrudes when the pressing portion is in an open state. When the sliding body is pushed by a gangster or other body, the pressing part is in a blocking state, and the gangster or other body can not pass through freely. Further, the fork described in jp 2003-254697 a has a pneumatic cylinder attached to a middle portion of the front side of the left and right pressing portions to which the support member is fixed at the end. By manually operating the operating lever of the fork, the pneumatic cylinder can be operated to close the left and right pressing portions.

Patent document 1: japanese patent laid-open No. 2000-230800

Patent document 2: japanese patent laid-open publication No. 2003-254697 (see FIG. 17)

Both the fork-type catching prop and the fork described in the above-mentioned publication enclose the body of a gangster or the like, and thus the gangster or the like cannot move freely, so that the pressing part is large and is not easy to operate. Further, since the body of a ruffian or the like, which acts violently, is not held at a certain angle, even if the long handle is held with both hands, the body is hindered by surrounding obstacles, clothing, or the like, and it is difficult to enclose the periphery of the body with the pressing portion.

Further, since the fork has a large pressing portion formed in a bifurcated shape at the distal end of the long shank, the fork cannot be mounted on a patrol car and is also difficult to transport and store. In addition, since the fork has a long handle, it is not suitable to cope with quickly. In addition, the fork is bound around the body, so that even if gangsters and the like cannot freely move, hands and feet can still freely move. Therefore, when gangsters hold a catcher such as a knife, gangsters cannot be caught too close to each other. The third person must be used to make the hands and feet of the ruffian unable to move freely, so as to completely restrain the ruffian.

Handcuffs are used as members for restraining the wrists of gangsters and preventing the wrists from moving freely. However, before the handcuffs are worn on both hands of ruffians, the ruffians may be injured by the handcuffs. Therefore, when the handcuffs are used, it is necessary to bind the body of ruffians and the like, so that the ruffians and the like cannot freely move.

Disclosure of Invention

As described above, the fork and the handcuffs are respectively long and short, so that gangsters cannot be dealt with immediately on site. The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a fork-type openable body-restraining device which prevents a body from being injured by ruffians and the like, and which restricts the freedom of the hands and feet of the ruffians and the like, thereby facilitating the arrest of the ruffians and the like.

In order to achieve the above object, the present invention has the following structure. A fork-type openable/closable body-restraining device of the present invention is constituted by a restraining part provided at one end of an operating lever, and a locking part provided on the operating lever.

The bound portion is formed by fixing a pair of independent clamping members having curved surfaces on the inner sides to the front end portions of slide rods slidably inserted into the operating rod, slidably inserting the slide rods through support portions fixed to the front end portions of the operating rod, and pivotally mounting the end portions of the swing plates pivotally mounted to both end portions of the support portions to the pair of clamping members so as to be rotatable.

The locking portion includes: a rack-type engaging portion having a serration formed on a slide member fixed to the slide bar; and an engaging portion having an engaging piece engaged with the rack engaging portion, wherein when the rack engaging portion is engaged with the engaging piece, the slide member is slid only in a direction of a rear end portion of the operating lever and is not slid in a direction of the bound portion.

When the slide member and the slide rod slide in the direction of the rear end portion of the operating rod to retract the support member, the pair of holding members are closed.

The pair of holding members may be provided at their distal ends with guide rollers for guiding the hands and feet inward, or may be perforated to reduce the weight. Further, it is preferable that the pair of gripping members are each rotatably and pivotally attached to a support member fixed to the distal end portion of the slide bar, but only one of the pair of gripping members may be rotatably and pivotally attached to the support member so as to be openable and closable.

The spring provided in the operating lever can apply a biasing force to the sliding member in the direction of the rear end portion of the operating lever or in the direction of the bound portion. When a spring that urges the slide member in the direction toward the rear end of the operating lever is provided, the pair of gripping members can be quickly closed, and conversely, when a spring that urges the slide member in the direction toward the bound portion is provided, the pair of gripping members can be quickly opened. In the case where a spring that urges the slide member in the direction toward the rear end portion of the operation lever is provided, it is preferable that the operation lever be provided with a spring pressure holding portion including an engagement hole provided in the slide member and a claw that is inserted into the engagement hole so as to be capable of protruding or retracting, in order to hold the open state of the pair of sandwiching members.

Further, the operation lever and the slide member inserted into the operation lever may be made extensible and contractible. When the pair of gripping members are opened, the slide member is urged toward the rear end of the operating lever by a spring attached to the slide rod or the slide member in the operating lever. In the case where a spring for biasing the sliding member in the direction toward the bound portion is provided, the operating portion may be provided in the operating lever, and the sliding member may be forcibly pulled toward the rear end portion side of the operating lever by operating the operating portion, so that the supporting member is retracted and the clamping member is closed.

Further, the support member and the slide bar can be connected to each other so as to be freely rotatable, and the swing plate can be formed of a flexible material, so that the angle formed by the clamp member and the operation lever can be changed.

The fork type openable and closable body binding equipment can be operated by one hand, and can bind the body of a ruffian and the like who violently resist against the body while ensuring the safety of the body. Further, the fork-type openable and closable body-restraining device can be used for defense against attacks like a baton, and since the device is not bulky, it can be mounted on a patrol car or the like and can cope with an emergency situation at random.

Further, as with handcuffs, the gripping member is not opened until the locked state is released once it is closed, and thus the freedom of movement of gangsters and the like can be restricted continuously.

Detailed Description

Next, specific embodiments of the fork-type openable and closable body-binding apparatus according to the present invention will be described with reference to the accompanying drawings. Fig. 1 is a partially sectional plan view showing a first embodiment of a fork-type openable and closable body-restraining device (hereinafter simply referred to as a body-restraining device) of the present invention, fig. 2 is a side view of a restraining part, and fig. 3 is an exploded perspective view showing a part of the restraining part.

The body restraint device 1A shown in the figure includes a restraint part 2, a lock part 3 for locking when the restraint part 2 is closed, and a spring pressure holding part 5 for holding a clamp member of the restraint part 2 in an open state. The binding portion 2 is provided at one end of a tubular operating lever 10, and the locking portion 3 and the spring pressure holding portion 5 are formed on the operating lever 10.

More specifically, the binding portion 2 includes a pair of independent clamping members 11, 11 that can be opened and closed freely. The holding members 11, 11 are substantially L-shaped in plan view, and have curved surfaces 11a, 11a formed on the inner side surfaces thereof so as to hold and restrain the body of a gangster, particularly the hand or foot. Further, the inner ends 11b and 11b of the holding members 11 and 11 are pivotally mounted to a support member 15 so as to be freely rotatable, the support member 15 is fixed to the front end of the slide bar 13, and the rear end of the slide bar 13 is slidably inserted into the operation tube 10. Outer corner portions 11c, 11c of the clamping members 11, 11 are pivotally mounted on one end of the swing plate 17 so as to be freely rotatable.

The other end of the swing plate 17 is pivotally attached to both ends of a support 19, and the support 19 is attached to the tip of the operating rod 10. Therefore, when the support member 15 retreats and approaches the support 19 side, the outer corner portions 11c and 11c of the clamping members 11 and 11 are pivoted outward by the swing plate 17 to close the distal end portions of the clamping members 11 and 11. When the holding members 11, 11 are closed, a gap is formed by the curved surfaces 11a, and the hand or the instep is held in the gap.

Next, the clamping members 11, 11 will be described in more detail, and the clamping members 11, 11 have bent portions 11d, 11d at their intermediate portions so that the distal end portions can intersect after closing. By forming the bent portions 11d, the leading end portions of the bent portions 11d, 11d intersect each other vertically as shown in fig. 2. Since the gripping members 11, 11 have the curved surfaces 11a, 11a and can intersect by forming the curved portions 11d, the gripping members 11, 11 can gradually reduce the gap formed by the curved surfaces after closing, and can grip the hands and feet regardless of their thickness.

Guide rollers 20, 20 are attached to the front end portions of the gripping members 11, and the guide rollers 20, 20 serve as guide members for facilitating insertion of hands and feet. The guide rollers 20 and 20 are preferably rollers with a reverse rotation preventing function that rotate only to the inside and not to the outside. Further, since the guide rollers 20 and 20 guide the gripped hands and feet to the inside of the gripping members 11 and 11, the guide rollers 20 and 20 are attached to the front end portions of the gripping members 11 and 11 in opposite directions to each other.

The guide rollers 20 and 20 may be omitted, and a guide member having another structure may be used. For example, a guide plate that opens outward may be attached to the distal end of the clamping members 11, or only the distal end of the clamping members 11, 11 may be formed as a slope.

The slide rod 13, the support member 15, the swing plates 17, and the support 19 described above will be described in further detail with reference to fig. 3. The slide rod 13 is slidably inserted into the operating rod 10 through the tube portion 19a of the support 19, and the tip end portion thereof is fixed to the support member 15. The front end portion of the slide rod 13 is fixed to the support member 15 by protruding from the support 19 by a compression coil spring 16 mounted in the operating lever 10. The support member 19 is fixed to the operating lever 10.

The support member 15 includes a fitting hole 15a for fixing the slide bar 13 to the rear end surface, and a recess 15b into which the inner ends 11b, 11b of the clamping members 11, 11 are inserted. The inner ends 11b and 11b of the clamping members 11 and 11 are inserted into the recess 15b, and the clamping members 11 and 11 are rotatably mounted on the support member 15. The swing plates 17, 17 have recesses 17a, 17b formed at both ends thereof into which the clamping members 11, 11 and the support 19 are inserted, and the clamping members 11, 11 and the support 19 are pivotally mounted in the recesses 17a, 17b so as to be rotatable.

A protruding piece 13a is formed at an end of the slide rod 13, and a compression coil spring 16 is installed between the protruding piece 13a and a support member 19. The compression coil spring 16 biases the slider 13 toward the lock portion 3 and the spring pressure holding portion 5.

When the clamping members 11, 11 of the bound section 2 are opened, the slide rod 13 fixed to the support member 15 is pulled out and the compression coil spring 16 is compressed. On the contrary, when the compression coil spring 16 is released, the slide bar 13 and the support member 15 are retracted by the urging force of the compression coil spring 16. On the other hand, since the clamp members 11, 11 are prevented from moving backward by the swing plate 17, the clamp members 11, 11 close the guide rollers 20 while rotating about the inner end portion 11 b. At this time, since both end portions of the swing plate 17 are pivotally attached to each other so as to be rotatable, the outer corner portions 11c and 11c on the side of the clamping members 11 and the swing plate 17 rotate outward, and the clamping members 11 and 11 can be smoothly closed.

In the above embodiment, the clamping members 11, 11 can intersect each other by forming the bent portions 11d, 11 d. In order to allow the clamping members 11, 11 to intersect with each other, the clamping members 11, 11 may be mounted in advance with a height difference in the vertical direction when the clamping members 11, 11 are mounted on the support member 15 without forming a bent portion. When the clamping members 11, 11 are mounted in a crossing manner, the inner gap can be gradually reduced.

The clamping members 11, 11 may abut against each other only in a butt manner without intersecting, and the clamping members 11, 11 may be brought close to each other. The shape of the clamping members 11, 11 is not particularly limited as long as they have a gap inside after clamping, and may be a shape that is curved as a whole, in addition to being formed in a substantially L-shape as shown in fig. 1.

The structure of the lock portion 3 is explained next. The locking portion 3 is a mechanism for locking the clamping members 11, 11 of the restraint portion 2 in the closed state. As shown in fig. 1, the lock portion 3 is formed of a rack-type engaging portion 23 having a serration 23a and an annular locking portion 25 having a locking piece 25a protruding from an inner surface thereof. The rack-type engaging portion 23 is formed at the rear end portion of the slide member 27, the slide member 27 is fixed to the rear end portion of the slide rod 13, and the annular engaging portion 25 is fitted into the inner surface of the operating lever 10.

The serration 23a of the rack-type engaging portion 23 engages with the locking piece 25a of the locking portion 25. When the compression coil spring 16 is compressed, the locking piece 25a is engaged with the spring pressure holding portion 5 side of the serration 23a, and when the compression coil spring 16 is released, the locking piece 25a is engaged with the slide bar 13 side of the serration 23 a. The slide member 27 is slidably inserted into a support ring 28, the support ring 28 is disposed inside the operating lever 10, and the slide member 27 moves forward and backward integrally with the slide bar 13.

A pressing member 31 for pressing the rack-type engaging portion 23 toward the locking portion 25 is provided near the rack-type engaging portion 23 and the annular locking portion 25. The pressing member 31 presses the rack engaging portion 23 at the distal end portion by a pressing spring 31a provided on the inner surface side of the operating lever 10.

Since the locking piece 25a and the serrations 23a have a serration inclined surface only on one side, the slide bar 13 and the slide member 27 are normally prevented from sliding toward the bound section 2 by engaging the serrations 23a with the locking piece 25a by the pressing member 31. As described above, when the clamping members 11, 11 are closed, the rack-type engaging portion 23 and the locking portion 25 lock the closed state of the clamping members 11, and the gangster can be restrained like a handcuff to restrict the freedom of the gangster's hand or foot.

On the other hand, when the pressing member 31 is pulled out to release the engagement state of the serration 23a with the locking piece 25a, the slide rod 13 and the slide member 27 can slide toward the bound portion 2. Therefore, the clamping members 11, 11 can be opened while releasing the engagement state of the serrations 23a and the locking pieces 25 a.

The slide member 27 may be either a rod-like member or a plate-like member. In the case where the slide member 27 is formed by a curved plate spring, the rack-type engaging portion 23 can be pressed toward the engaging portion 25 by providing the rack-type engaging portion 23 on the curved outer surface, and the pressing member 31 can be omitted. In this way, in the case where the slide member 27 is formed by a plate spring, the pressing member 31 may be provided on the opposite side of the position in the embodiment so that the engagement state between the serration 23a and the locking piece 25a can be released.

Next, the spring pressure holding portion 5 will be described. As shown in fig. 1, the spring pressure holding portion 5 is configured such that a locking hole 27a is formed in the rear end portion of the slide member 27, and an insertion pin 33a of a press-in pin 33 attached to the rear end portion of the operating lever 10 is inserted into the locking hole 27 a. The push-in pin 33 is formed in a substantially く shape as a whole, and the insertion pin 33a protruding into the operation lever 10 is axially attached to the insertion pin 33a so as to be vertically movable.

In order to insert the insertion pin 33a into the locking hole 27a, after the engagement state between the serration 23a and the locking piece 25a is released, the locking hole 27a is advanced to the position of the insertion pin 33a while compressing the compression coil spring 16. When the insertion pin 33a is inserted into the locking hole 27a, the compressed state of the compression coil spring 16 can be maintained, and the open state of the clamp members 11, 11 can be maintained. After the open state of the clamping members 11, 11 is maintained, the pressing member 31 may be pushed in to engage the serrations 23a with the locking piece 25 a.

In order to close the holding members 11, the insertion pin 33a is pulled out from the locking hole 27a in reverse to the operation when the holding members 11, 11 are opened, and at this time, the slide member 27 and the slide rod 13 slide in a rear end direction at once by the urging force of the compression coil spring 16, thereby closing the holding members 11, 11. When the clamping members 11, 11 are closed, the locking part 3 locks the closed state of the clamping members 11, so that the hand and foot of a gangster can be reliably restrained.

Next, a second embodiment shown in fig. 5 will be explained. The compression coil spring 16 is used in the above embodiment, and a tension spring is used in the embodiment shown in fig. 5, unlike this. Therefore, the same components as those in the above embodiment are denoted by the same reference numerals, and description thereof is omitted. In the embodiment shown in fig. 5 (a), a coil spring 44 is disposed inside a cap 43 fitted to the rear end surface of the operating lever 10, and the tip of the coil spring 44 is attached to the slide member 27.

Therefore, when the insertion pin 33a is pulled out from the locking hole 27a, the slide member 27 and the slide rod 13 are pulled to the cap 43 side, and the clamp members 11, 11 are closed. In the embodiment shown in fig. 5 (b), a tension coil spring 48 is used instead of the coil spring 44. One end of the tension coil spring 48 is attached to the cap 43, and the other end is attached to the slide member 27. The embodiment of fig. 1 is different from the embodiment of fig. 5 in that a compression coil spring is used in fig. 1, and a tension spring is used in fig. 5, and the other structures are the same.

The third embodiment shown in fig. 6 is the same as the embodiment of fig. 1 in that the compression coil spring 16 is used in each case, but the compression coil spring 16 closes the clamp members 11, 11 by pushing up the support member 19. In the present embodiment, the same components as those in the embodiment of fig. 1 are denoted by the same reference numerals, and description thereof is omitted.

The binding portion 2A has a pair of independent arc-shaped clamping members 11A, 11A that can be opened and closed freely. When the holding members 11A, 11A are closed, a substantially circular space is formed inside, and thus the body of a gangster, particularly the hand or foot, can be held and restrained in the circular space. As in the first embodiment, the clamping members 11A and 11A are pivotally mounted to a support member 15, and are pivotally mounted to one end of a swing plate 17, and the support member 15 is fixed to the tip end of the slide bar 13. The other end of the swing plate 17 is pivotally mounted on both ends of the support 19.

Here, the support 19 is not axially mounted on the front end of the operating lever 10 unlike the above embodiment, and therefore the support 19 and the operating lever 10 can be separated from each other although the slide rod 13 is slidably inserted into the support 19. Thus, the compression coil spring 16 can push up the support member 19. When the support 19 is pushed up, the holding members 11A and 11A are also pushed up via the swing plates 17 and 17. At this time, since the inner end portions 11b of the gripping members 11A and 11A are rotatably and axially mounted on the support member 15, the gripping members 11A and 11A close the guide rollers 20 while rotating about the inner end portions 11 b.

In the present embodiment, it is also preferable that the bent portions 11d and 11d be formed in the intermediate portions of the gripping members 11A and 11A so that the tip portions of the gripping members 11A and 11A can intersect with each other to gradually reduce the gap formed by the bent surfaces when the gripping members 11A and 11A are closed.

Next, a fourth embodiment of the fork-type openable and closable body-binding apparatus of the present invention will be described with reference to FIGS. 7 and 8. The illustrated body restraint device 1B includes a restraint section 2, a lock section 3B for locking the restraint section 2, and an operation section 4 for manually closing the restraint section 2. The binding portion 2 is provided at one end of a tubular operating lever 10, and the locking portion 3B and the operating portion 4 are formed in the operating lever 10. The structure of the binding portion 2 is the same as that of the above embodiment. Therefore, the same components as those in the above embodiment are denoted by the same reference numerals, and description thereof is omitted.

Since the swing plate 17 is pivotally attached to the clamping members 11, 11 at its front end and to the support 19 at its rear end, when the support member 15 is pushed from the open state of the clamping members 11, 11 and the support member 15 is retracted toward the operation lever 10, the clamping members 11, 11 are prevented from being retracted by the swing plate 17. Therefore, the clamping members 11, 11 close the guide roller 20 side while rotating about the inner end portion 11 b. At this time, the outer corner portions 11c, 11c on the side of the clamping members 11, 11 and the swing plate 17 are rotated to be opened outward, and the clamping members 11, 11 can be smoothly opened and closed. The opening and closing manner of the holding members 11, 11 is the same as that of the first embodiment and the like.

In the above embodiment, in order to cross the clamping members 11, the bent portions 11d, 11d may be formed at the intermediate portions of the clamping members 11, or the clamping members 11, 11 may be mounted to the support member 15 in advance with a height difference in the vertical direction. The clamping members 11, 11 may abut against each other only in a butt manner without intersecting, and the clamping members 11, 11 may be brought close to each other. The shape of the clamping members 11, 11 is not limited to the shape of the above embodiment as long as they have a gap inside after clamping.

Next, the structure of the lock portion 3B is explained. The locking portion 3B locks the clamping members 11, 11 of the bound portion 2 in the closed state, similar to the locking portion 3 shown in fig. 1. In the present embodiment, the sliding member 27 forming the rack-type engaging portion 23 of the lock portion 3B is slidably inserted into the support rings 28 and 29. A pressing spring 30 that applies a biasing force to the slider 13 toward the distal end side (the bound portion 2 side) is attached between the support ring 28 and the rear end surface of the slider 13. When the support member 15 protrudes together with the slide rod 13 by the urging spring 30, the clamp members 11, 11 are opened by the swing plates 17, 17.

In the present embodiment, the lock portion 3B is provided with a press-in pin 32 that is pressed into the rack-type engaging portion 23 against the pressing force of the pressing member 31. The press-fitting pin 32 includes a press-fitting portion 32d and an insertion pin 32e, and a spring 32a provided on the outer surface of the operation lever 10 biases the press-fitting portion 32d outward of the operation lever 10. The engagement state between the rack-type engagement portion 23 and the engagement portion 25 is released by pushing the push-in portion 32d against the urging force of the spring 32 a.

In the present embodiment, when the support member 15 is pushed in, the slider 13 and the slide member 27 move backward to close the clamp members 11, 11. At the same time, the closed state of the clamping members 11, 11 is locked by the rack-type engaging portion 23 and the locking portion 25. That is, pressing only the hand or foot of a gangster can restrict the gangster's freedom of movement like a handcuff.

Further, when the clamping members 11, 11 are closed to a certain degree, the clamping space between the clamping members 11, 11 is reduced as the supporting member 15 is pushed in, and thus the gangster is more strongly resisted and more reliably restrained. When the gangster escapes from the restraint in the initial state of the lock, the pushing portion 32d is pushed in, and the locked state can be released by one-handle operation (one touch) by the urging force of the pressing spring 30, so that the gangster can quickly cope with the subsequent action.

Next, the operation unit 4 will be explained. The operation portion 4 also serves as a cap for the rear end face of the operation rod 10, and pulls the rack-type engagement portion 23 of the lock portion 3B to lock the clamping members 11, 11. That is, the operation unit 4 is composed of the cap 35 and the coupler 36. A cap 35 is formed by a grip portion 33 having a larger diameter than the operation lever 10 and an insertion portion 34 inserted into the operation lever 10, and the insertion portion 34 and the rear end portion of the slide member 27 are coupled to each other by a coupling 36.

The length of the fastener 36 is adjusted so that the grip members 11, 11 are in a state of being opened to the maximum extent when the fitting portion 34 is fitted into the operating lever 10 and the grip portion 33 is brought into contact with the end face of the operating lever 10. Since the cap 35 is connected to the slide member 27 via the coupling 36, when the handle portion 33 is pulled and the fitting portion 34 is retracted, the slide member 27 is retracted at the same time, the clamping members 11, 11 are closed, and the closed state is locked by the rack-type engaging portion 23 and the locking portion 25.

The operation portion 4 can effectively close the gripping members 11, 11 even if the support member 15 is not sufficiently pushed in. The length of the operating lever 10 is not particularly limited, and may be any length that can prevent a person from being exposed to the danger of gangsters or the like and can be quickly handled by one hand. For example, it may be formed to have the same length as a normal baton or a slightly longer length.

Next, a fifth embodiment of the binding portion 2A shown in fig. 9 will be described. In the fifth embodiment shown in fig. 9, one side of the clamping members 11, 11 is fixed and the other side is freely opened and closed. The structure of the present embodiment is the same as that of the embodiment shown in fig. 1 and 7, and a binding portion 2B is shown in the figure.

The bound portion 2B has holding members 11B, 11B of substantially the same shape, and holds a holding member 11B (the left holding member 11B in fig. 9) in a closed state. That is, a holding member 11B is not shaft-mounted to the support member 15, but is fixed to the other end portion of the fixed plate 38, and the fixed plate 38 is fixed to the support 19. Therefore, the fixed clamping member 11B does not open or close regardless of the forward or backward movement of the support member 15.

Since the inner end 11B of the other clamping member 11B (the right clamping member 11B in fig. 9) is pivotally mounted to the support member 15 so as to be rotatable, and the outer corner 11c is rotatably connected to the swing plate 17, the support member 15 can move forward and backward, and the other clamping member 11B can be opened and closed. In the present embodiment, the same lock portions 3 and operation portions 4 as those of the fourth embodiment shown in fig. 7 are provided, and therefore, the description of the lock portions 3 and operation portions 4 is omitted.

Next, a binding portion 2C of a sixth embodiment shown in fig. 10 will be described. The embodiment shown in fig. 10 is different from the above-described embodiments in that 2 bent portions are formed in the clamping members 40, 40. That is, the clamping members 40, 40 have curved surfaces 40a, 40a and curved surfaces 40b, 40b on the inner sides. Guide rollers 41, 41 for inwardly guiding the hands and feet are attached to the distal end portions of the gripping members 40, and guide rollers 42, 42 are similarly attached to the protruding portions constituting the boundary portions between the curved surfaces 40a, 40a and the curved surfaces 40b, 40 b.

A part of the guide rollers 42, 42 protrudes toward the inside of the gripping members 40, and preferably has an anti-reverse mechanism. Further, the inner ends 40c and 40c of the holding members 40 and 40 are pivotally mounted to the support member 15 so as to be freely rotatable, the support member 15 is fixed to the distal end of the slide bar 13, and the slide bar 13 is slidably inserted into the operating lever 10. The swing plates 17, 17 are pivotally mounted on outer end edges of the clamping members 40, 40 so as to be freely rotatable, and the other end portions of the swing plates 17, 17 are pivotally mounted on the support 19.

As described above, when the grasping member having 2 curved surfaces is provided, for example, the ankle can be grasped between the curved surfaces 40a and 40a on the distal end side and the wrist can be grasped between the curved surfaces 40b and 40b on the support member 15 side, and the body can be reliably restrained by the grasping portion.

The guide rollers 41 and 42 may be omitted, and the clamping members 40 and 40 may be formed to have a shape that can intersect with each other by providing the bent portions 11a in the clamping members 40 and 40. The same components as those in the first and second embodiments are denoted by the same reference numerals, and description thereof is omitted.

Next, a seventh embodiment of the binding portion shown in fig. 11 to 13 will be described. The operating lever 10 and the clamping members 11, 40 forming the bound portions 2, 2A, 2B, and 2C in the first to sixth embodiments are integrally formed in a linear shape, and the orientation of the operating lever and the clamping members cannot be changed. However, in the present embodiment, as is clear from fig. 13, the angle formed by the operating lever and the clamping member can be changed. The present embodiment is different from the first to sixth embodiments in that the orientation of the gripping member can be changed.

The slide bar 13 and the support member 15 are pivotally mounted to be rotatable. That is, the slide bar 13 and the support member 15 are rotatably assembled by the pin 44 by inserting the projecting portion 13a between 2 holding plates 15a, the projecting portion 13a projecting toward the tip of the slide bar 13, and the holding plates 15a, 15a projecting in parallel from the support member 15. The swing plate 17 supporting the clamping members 11, 11 is formed at its central portion with a flexible member 17a having flexibility such as a coil spring, a leaf spring, a rubber member, or a resin material.

Since the slide bar 13 and the support member 15 are pivotally mounted to be rotatable and the flexible member 17a forms the central portion of the swing plate 17, the angle formed by the operation lever 10 and the clamping members 11 and 11 can be changed (see fig. 13). Since the angles of the holding members 11, 11 of the binding portion 2 can be changed as described above, even when a gangster or the like acts violently, the force of binding can be weakened in accordance with the action of the gangster or the like, and the hand and foot of the gangster to be bound are not damaged even in a state where the holding members 11, 11 are locked.

The configuration in which the angle formed by the slide bar 13 and the support member 15 can be changed is not limited to the above-described embodiment, and may be any configuration, and for example, the coupling portion formed by the grip plates 15a, 15a and the protruding portion 13a may be formed as a universal joint structure.

Next, another embodiment of the locking portion and the operation portion shown in fig. 14 to 16 will be described. Fig. 14 shows a second embodiment of the locking portion. The locking portion 3C is configured oppositely to the locking portion in the first embodiment shown in fig. 1 and 7, and includes: a locking cylinder 46 provided with a plurality of rows of serrations 45; a locking piece 47 which is engaged with the serration 45; and a press-fitting pin 32 for releasing the engagement between the serration 45 and the locking piece 47. The locking cylinder 46 is inscribed in the inner surface of the operating lever 10, and the locking piece 47 is provided at the rear end of the slide member 27.

In a state where the serration 45 is engaged with the locking piece 47, the locking piece 47 is slidable toward the rear end side of the operating lever 10 but is not slidable toward the bound section 2. Thus, the clamping members 11, 11 of the bound portion 2 are locked in the closed state. By pushing the push-in pin 32, the engagement state is released, and the locking piece 47 can move forward toward the bound portion 2. The tip end of the press-fit pin 32 protrudes inward of the operation lever 10 and approaches the slide member 27. The press-fit pin 32 has the same structure as the press-fit pin 32 shown in fig. 7, and therefore, the description thereof is omitted.

Fig. 14 shows a second embodiment of the operation unit. The operation portion 4A is configured by coupling the slide member 27 to the lock lever 50 attached to the outer surface of the operation lever 10 via the coupling 51. Therefore, when the lock lever 50 is gripped and the lock lever 50 is depressed, the slide member 27 is pulled by the coupling 51, and the slide member 27 retreats while engaging the locking piece 47 with the serration 45. The lock lever 50 may be used when the grip members 11, 11 are closed quickly, as in the handle portion 34 of the first embodiment shown in fig. 7.

The configuration of the binding portion, the configuration of applying the urging force to the slide member 27 by the compression coil spring 16, and the like are the same as those of the above-described embodiment. Therefore, when the press-fitting pin 32 is pressed to release the engagement between the serration 45 and the locking piece 47, the slide member 27 moves forward, and the clamp members 11 and 11 are opened.

Next, a third embodiment of the locking portion and the operating portion shown in fig. 15 and 16 will be described. The locking portion 3D shown in fig. 15 and 16 has the following structure. That is, the slide member 27 is connected to a slide tube 53 that slides in the operation lever 10, and a plurality of locking holes 53a are formed in the slide tube 53 in the axial direction. The insertion portion 55a of the press-fit pin 55 attached to the operation lever 10 is fitted in the locking hole 53 a.

The press-fitting pin 55 is formed into a substantially く shape as a whole by the press-fitting portion 55b and the insertion portion 55a, and the insertion portion 55a protruding into the operation lever 10 is formed so as to be vertically movable. Further, an inclined surface facing the distal end side (the binding portion 2 side) of the operation lever 10 is formed at the distal end of the insertion portion 55 a. On the other hand, the tip end side (the binding portion 2 side) of the locking hole 53a is also formed by an inclined surface. Therefore, when the slide pipe 53 is retracted, the inclined surface of the insertion portion 55a comes into contact with the inclined surface of the locking hole 53a, and the slide pipe 53 can slide smoothly. The slide tube 53 does not slide toward the distal end side (the restricting portion 2 side) of the operating lever 10 due to the locked state of the insertion portion 55a and the locking hole 53 a.

The insertion portion 55a and the locking hole 53a can only retreat by the inclined surface. When the locking state between the insertion portion 55a and the locking hole 53a is to be released, the rear end portion of the press-fitting portion 55b of the press-fitting pin 55 is press-fitted to lift the insertion portion 55 a. The slide tube 53 is advanced by the urging force of the urging spring 30, and the gripping members 11, 11 are opened.

On the other hand, the operation portion 4B of the third embodiment is formed by slidably inserting the lock lever 59 into the substantially L-shaped slit 57 provided in the operation lever 10, and fixing the tip portion 59a of the lock lever 59 to the slide tube 53 by projecting into the operation lever 10. The slit 57 is formed into a substantially L-shape by a slit 57a in the axial direction of the operation rod 10 and a slit 57b in the circumferential direction of the operation rod 10.

Therefore, when the lock lever 59 is pulled to retract the lock lever 59 in the slit 57a, the slide tube 53 also retracts. Further, as the slide tube 53 retreats, the insertion portion 55a is locked while repeating locking with the locking hole 53 a. As with the cap 35 shown in fig. 7, the lock lever 59 may be used when it is desired to quickly close the gripping members 11, 11 before the gripping members 11, 11 are brought into the closed state by pressing the support member 15.

When the lock lever 59 is pulled and the lock lever 59 is locked in the slit 57b, the slide tube 53 is retracted to lock the clamping members 11, 11 in a closed state. To release the locked state of the holding members 11, the lock lever 59 is rotated from the slit 57b to the slit 57a, and the rear end of the press-fitting pin 55 is pressed in to lift the insertion portion 55 a. Since the slide member 13 connected to the slide tube 53 is pressed to the distal end side of the operating lever 10 by the coil spring 30, when the engagement state between the insertion portion 55a and the engagement hole 53a is released, the support member 15 is returned to place the clamp members 11, 11 in the open state.

The structure of the binding portion in the embodiments shown in fig. 14 to 16 may be the structure of any one of the binding portions in the first to seventh embodiments.

Next, a ninth embodiment of the locking portion and the operating portion will be described with reference to fig. 17 to 20. The operation lever 10A in the present embodiment and the slide member 27A inserted into the operation lever 10A can be extended and contracted. The operating lever 10A is constituted by a first tubular body 61 and a second tubular body 62 into which the tubular body 61 is inserted, and the slide member 27A is constituted by a first slide member 64 and a second slide member 65 which is insertable into the first slide member 64.

More specifically, the support 19 is fixed to the front end of the first tubular body 61, and a fixing pin 66 that can be freely inserted or inserted is provided to the rear end of the first tubular body 61. Through holes 67, 68 are formed in the second tubular body 62 into which the first tubular body 61 is inserted, and the fixing pins 66 can be fitted into the through holes 67, 68. The through hole 67 is provided at a position where the fixing pin 66 is inserted when the first tubular body 61 and the second tubular body 62 are elongated. The through hole 68 is provided at a position where the fixing pin 66 is fitted when the first tubular body 61 is inserted into the second tubular body 62 to shorten the operation lever.

The first slide member 64 forming the slide member 27A is a tubular body into which the second slide member 65 is inserted, and has a front end fixed to the slider 13 and a rear end to which a support ring 69 through which the second slide member 65 is inserted is attached. The second slide member 65 is slidably inserted through the support ring 69, and a stopper 70 for preventing the second slide member 65 from coming off the support ring 69 is fixed to a distal end portion of the second slide member 65. The rear end of the second slide member 65 is slidably inserted into a support ring 71, and the support ring 1 is fixed in the second slide member 65.

A compression coil spring 16a is attached to the outer periphery of the first slide member 64. The compression coil spring 16a is interposed between the slider 13 and an engaging piece 85 fixed to the inner surface of the first tubular body 61, and applies a biasing force to the bound portion side.

As is clear from the above description, when the first and second tubular bodies 61 and 62 are extended and the fixing pin 66 is fitted into the through hole 67, the second slide member 65 of the slide member 27A is pulled out from the first slide member 64, and the stopper 70 is engaged with the support ring 69, as the operating lever 10A and the slide member 27A are slid. In addition, the second slide member 65 is inserted into the first slide member 64 while the first tubular body 61 is inserted into the second tubular body 62 with the fixing pin 66 embedded in the through hole 68.

Next, the structure of the lock portion 3E, the operation portion 4C, and the spring pressure holding portion 5C provided in the operation lever 10A and the slide member 27A will be described. The lock portion 3E includes a serration 72 provided on an inner surface of the second tubular body 62, an engagement piece 73 engaged with the serration 72, and an unlocking pin 74 press-fitted into the engagement piece 73.

The serrations 72 are formed directly on the inner surface of the second tubular member 62, but a cylindrical body having the serrations 72 formed on the inner surface thereof may be inserted into the inner surface of the second tubular member 62. The locking piece 73 has a through hole 75 into which the lock release pin 74 is inserted, and the slide bar 76 moves forward and backward in the second tubular body 62 by applying an outward urging force to an aperture 77 formed in the slide bar 76 by a spring 78. The second slide member 65 is fixed to the distal end portion of the slide bar 76, and the slide bar 76 moves forward and backward integrally with the second slide member 65.

A pressing spring 79 is attached between the front end surface of the slide bar 76 and the fixed support ring 71, and the pressing spring 79 applies a biasing force to the slide bar 76 toward the rear end portion side of the second tubular body 62 (the direction opposite to the bound portion side). Preferably, the spring force of the pressing spring 79 is larger than the spring force of the compression coil spring 16 a. On the other hand, the slit 77 is formed in the rear end portion of the slide bar 76, and a pin hole 80 into which the lock release pin 74 is inserted is bored.

The relationship between the locking piece 73 and the lock release pin 74 is described with reference to fig. 19 and 20. When the lock release pin 74 is retracted by the pressing spring 81, the spring 78 pushes up the locking piece 73, and the center of the through hole 75 is displaced from the center of the pin hole 80 of the slide rod 76. When the tip of the lock release pin 74 is inserted into the through hole 75 and the pin hole 80, the locking piece 73 is pressed against the urging force of the spring 78, and the through hole 75 is aligned with the center of the pin hole 80. When the through hole 75 is aligned with the center of the pin hole 80, the engagement state of the locking piece 73 with the serration 72 is released, and the slide rod 76 can advance and retreat.

The rear end portion of the lock release pin 74 is fixed to a cap guide rod 82, and the pressing spring 81 is fixed to an intermediate portion of the lock release pin 74, and a spring support plate 83 that slides in the second tubular body 62 is attached. The unlocking pin 74 is pushed out from the through hole 75 of the locking piece 73 by a pressing spring 81 attached between the spring support plate 83 and the slide bar 76.

Therefore, when the unlocking pin 74 is pushed in, the spring support plate 83 also moves forward while compressing the pressing spring 81 integrally with the unlocking pin 74, and the unlocking pin 74 is inserted into the through hole 75 of the locking piece 73. When the lock release pin 74 is inserted into the through hole 75, the engagement between the locking piece 73 and the serration 72 is released because the locking piece 73 is pushed in. The cap guide rod 82 is inserted into the second tubular body 62 so as to be movable forward and backward while being guided by a locking pipe joint (10ck nipple)86 fixed to the rear end portion of the second tubular body 62.

Next, a lock mechanism that assists the above-described lock portion 3E will be explained. The auxiliary locking mechanism 3F is constituted by a locking pipe joint 86, a locking cap 88, and an elastic member 91. That is, a part of the locking pipe joint 86 is fixed to the second tubular body 62 so as to protrude from the second tubular body 62, and a male thread 87 is engraved on the outer peripheral surface of the protruding portion. An internal thread 89 to be screwed with the external thread 87 is formed on an inner peripheral surface of the locking cap 88.

A recess 90 is provided on the inner peripheral surface of the lock cap 88, and an elastic member 91 is attached between the recess 90 and the lock pipe joint 86. When the fastened state of the lock cap 88 and the lock pipe joint 86 is loosened, the concave portion 90 becomes large, the pressing of the elastic member 91 against the cap guide rod 82 is released, and the cap guide rod 82 can smoothly slide. Conversely, when the lock cap 88 is tightened, the elastic member 91 is compressed between the lock cap 88 and the lock pipe joint 86 to press the cap guide rod 82, and the cap guide rod 82 is locked in advance and retreat.

The auxiliary lock mechanism 3F locks the closed state of the clamp members of the restricting portion by engaging the serration 72 and the locking piece 73 constituting the lock portion 3E, but when the cap guide rod 82 slides toward the front end portion side (restricting portion side), the locked state is released by the lock release pin 74. Therefore, the auxiliary lock mechanism 3F prevents the locking piece 73 from being pushed in by the lock releasing pin 74 of the lock portion 3E by the lock cap guide rod 82. Further, when the slide member 27A is not sufficiently retracted and the holding member is not sufficiently held, the thieves and the like can be reliably restrained by pulling the cap guide rod 82 by hand. This function is the same as the cap 35 shown in fig. 7, and the locking lever 59 shown in fig. 16.

Next, the spring pressure holding portion 5C that holds the open state of the clamping member of the restraint portion will be described. As shown in fig. 17 and 18, the spring pressure holding portion 5C is formed by a fixing pin 93 inserted in the slide bar 76 and a pin hole 94 bored in the second tubular body 62. The fixing pin 93 is inserted into an insertion hole 95, the insertion hole 95 is inserted into the slide bar 76, and a spring 96 attached to the bottom of the fixing pin 93 urges the fixing pin 93 outward so that the tip of the fixing pin 93 protrudes from the pin hole 94 of the second tubular body 62. When the engagement state between the serration 72 and the locking piece 73 is released, the support member 15 is advanced while compressing and pressing the coil spring 79, and the fixing pin 93 is fitted into the pin hole 94, the open state of the clamping member of the restraint portion can be maintained.

The body-restraining section 2D of the body-restraining device according to the ninth embodiment is different from the embodiments shown in fig. 1, 6, and 7 in that the holding members 11C and 11C do not have guide rollers, and a plurality of through holes 97 are provided to reduce the weight, and the other configurations are the same as those of the embodiments shown in fig. 1, 6, and 7. Therefore, the same components are denoted by the same reference numerals, and descriptions thereof are omitted.

Next, a method of using the body-restraining device according to the ninth embodiment will be described. When the operation lever 10A is pressed while pushing in the fixing pin 93 at the moment when the ankle, wrist, or the like of a gangster or the like is inserted into the holding members 11C, the slide member 27A retreats toward the lock cap 88 side to engage the locking piece 73 with the serration 72, thereby establishing a locked state. Further, when a gangster or the like tries to break loose the holding members 11C, 11C or tries to tighten the gangster more firmly, the tip end portion of the cap guide rod 82 can be pulled.

In the present embodiment, the lock release pin 74 is inserted into the through hole 75 of the locking piece 73, and the locking piece 73 is press-fitted, thereby releasing the engagement between the locking piece 73 and the serration 72. Then, by operating the auxiliary lock mechanism 3F, the lock cap 88 can be tightened to compress the elastic member 91, and the cap guide rod 82 can be prevented from sliding.

Next, a method of using the body-restraining device 1A according to the first embodiment will be described with reference to fig. 21 and 22. As shown in fig. 21, the spring pressure holding portion 5 can be operated at the moment when an ankle such as a ruffian to be caught is inserted into the holding members 11, and the locked state can be released. In the embodiment shown in fig. 7 and the subsequent figures, the operation portion 4 is operated to pull the slide member 27. In the case of the embodiment shown in fig. 7 and the following figures, when the ankle such as a ruffian is strongly pressed without operating the operation unit 4, the support member 15 is pushed in by the ankle, and the slide member 27 is retracted against the urging force of the coil spring 30, and the holding members 11, 11 are closed.

In each of the above embodiments, since the closed state of the gripping member is directly held by the lock portion 3 when the slide member 27 is retracted, the hands and feet can be restrained by the gripping members 11, 11. The more violent the gangster or the like moves his or her foot, the greater the pushing in of the support member 15, and therefore the tighter the closing of the holding members 11, 11. Gangsters and the like, the feet of which cannot move freely because the ankles are bound, are difficult to stand, so that the gangsters and the like can fall over by operating the operating rod 10, and the gangsters and the like are easy to catch.

In addition, as shown in fig. 22, when the wrist of a ruffian or the like to be caught is bound, the hand of the ruffian or the like may be bound by the same method as that for binding the ankle. When the clamping members 11, 11 are closed to a certain degree and the wrist cannot be pulled out, the supporting member 15 is pushed in and tightened by the clamping member when a ruffian or the like moves, so that the ruffian or the like can be reliably restrained. Under the condition of constraining the wrist, even if gangsters and other gangsters hold the gangsters and other gangsters by hands, the gangsters and other gangsters can also abandon the gangsters, thereby protecting the body safety.

As can be seen from the above detailed description, the fork-type body-openable/closable restraint device according to the present invention can effectively restrain the hand and foot of a ruffian or the like instantaneously or while pressing the hand and foot of the ruffian or the like. Further, since the device can be operated with one hand to protect against an attack like a spontoon, the device can also effectively protect itself.
