Handcuff of preventing unlocking}

The present invention relates to an anti-cuff cuff, and more particularly, in the handcuff body having a step piece that is freely rotated within the frame by the rotation of the moving ring to be engaged with the tooth group of the moving ring. One or more inclined protrusions are formed on the side of the entrance port and the side corresponding to the entrance port. The present invention relates to a cuff for preventing release of handcuffs by preventing entry of metal flakes and the like.

In general, various types of handcuffs have been proposed, both domestically and internationally, to suggest the scope of behavior of offenders. However, this type of handcuffs can be operated by rotating the step piece while the criminal is inserting a hairpin or fine wire into the keyhole to unlock the handcuffs, or by applying a strong shock from the outside to cut or break the shaft to manipulate the step piece. By doing so, the handcuffs have been released.

Therefore, as described above, in order to prevent unauthorized release of the handcuffs, a stopper was installed to prevent the step piece from moving, but this also had a problem in that the step piece was easily released by pressing the stopper using a fine pin.

Accordingly, the present applicant has proposed Korean Utility Model Publication No. 93-204, Utility Model No. 93-2996, and 96-3984 to solve the above problems.

That is, in the case of No. 93-2996, the pivot shaft of the claw is removed, and the claw is rotated freely in the groove formed in the mechanism frame, to prevent unauthorized release of the cuff by removing the conventional claw, except for the key for unlocking the cuff. It is configured not to release the handcuffs.

In addition, in the case of No. 96-3984, as shown in FIG. 1, the movable ring 120 to be fastened to the wrist of the criminal is formed with a plurality of teeth groups 121 having a predetermined length from one end of the opened one direction. It is prevented by the foot piece 200 having three or four teeth 201 serving as a stopper, and can continue in the other direction, the foot piece 200 is a pair of two I adopt it.

In addition, the step piece 200 is elastically supported by the leaf spring 140 in the space (S) of the approximately '-' shape formed in the mechanism frame 130 installed in the body 100.

At this time, the diaphragm 300 is installed between the tool frame 130 and the tool frame 130.

Therefore, the teeth group 121 formed in the mobile ring 120 as described above is engaged with each step piece 200 installed up and down on the body 100, the pin penetrates from the outside to step the step piece 200 Even if attempting to release, the step piece 200 formed in the lower portion is protected by the diaphragm 300 is to be engaged with the teeth of the mobile ring as it is to prevent the release of handcuffs.

102 in the figure is a keyhole.

Therefore, when the handcuff configured as described above is pushed against the criminal's wrist by the moving ring 120, the moving ring 120 rotates with the pivot shaft P as a supporting point. At this time, the teeth group 121 formed in the mobile ring 120 passes through the fixing ring 110 to cover the wrist of the criminal, and the teeth 201 formed on the step piece 200 in the fixing ring 110 again. When engaged, the leaf spring 140 is moved to the lock groove 101 formed at the outside of the body 100 by the pin 21 formed at the rear of the key 20 of the handcuffs, so that the protrusion 210 of the step piece 200 is moved. By making the protrusion 141 of the leaf spring 140 abut, it is possible to prevent unauthorized release of the handcuffs.

However, the utility model 93-2996 or 96-3984, as shown in Figure 2a also pushes the thin plate 10 in the direction of movement of the moving ring 120, such as the moving ring 120 When the user pushes in the direction of arrow a, the moving piece 120 is lifted by the moving ring 120 and the thin plate 10. As shown in FIG. 2B, when the moving ring 120 is pulled in the direction of the arrow b, the handcuffs are easy. There is a problem that is released.

The present invention is to solve the problems as described above, the movement of the entrance to the handcuff body of the handcuff body having a step that is freely rotated in the frame by the rotation of the moving ring to fit the teeth of the mobile ring and the entrance One or more inclined projections are formed on the side corresponding to the metal foil to prevent entry of metal cuffs so as not to release the cuffs except for the cuff release key.

In order to achieve the above object, the present invention forms a circular arc and a predetermined width portion of one of the moving ring to form a tooth group, a pair of fixed ring connected to one end of the moving ring by a rotating shaft, and The fixing ring has a single body formed integrally with each other, and a guide pin fixed to the central portion of the body, a pair of mechanism frames provided between the two bodies and having a U-shaped space, and between the pair of mechanism frames. In the handcuff consisting of a guide pin which is inserted into the key hole and the center hole and axially supports the pair of walking pieces, and a plurality of fixing pins in a predetermined position for fixing the pair of bodies, the entrance to the moving ring of the handcuffs body One or more inclined protrusions are formed on the side and the side corresponding to the entrance port to prevent entry of metal flakes to prevent unauthorized release of handcuffs.

Hereinafter, the preferred embodiment of the present invention by the accompanying drawings in detail.

First, the same shape and name as in the prior art are denoted by the same reference numerals and description thereof will be omitted.

The present invention, as shown in Figure 3a, the moving ring 120 has a plurality of teeth group 121 is formed a predetermined length from one end is opened, three or four to act as a stopper in one direction It is prevented by the step piece 200 which has the tooth 201, and it can continue to advance to another direction.

That is, the movable ring 120 is installed to be rotatable about a hinge axis at one end of the fixed ring 110 formed on the body 100, and two sets of mechanism frames 130 are provided on the body 100. Are assembled. A diaphragm 300 is provided between the mechanism frames 130.

In addition, the frame 130 has a longitudinal cross-section of the approximately 'c' shape, coincides with the outer shape of the body 100, the leaf spring having an elastic force in the 'c' shaped space (S) 140 and the step piece 200 will be built.

In addition, the guide pin 103 is installed between the pair of mechanism frame 130 and inserted into the key hole and the center hole and axially supporting the pair of the step pieces 200.

In addition, one or more inclined protrusions 132 are formed on the side of the moving ring inlet of the body 100 and the side corresponding to the inlet so as to prevent entry of the metal foil 10 to prevent unauthorized release of the handcuffs. Configuration features are given.

As shown in the enlarged view of the main portion of Fig. 4a or 4b, the inclined protrusion 132 is one of the front and rear sides of the moving ring inlet and the side corresponding to the inlet, that is, the framework 130, or Two can be extended and injected.

In addition, as shown in FIG. 5A, the diaphragm 300 and the pair of mechanism frames 130 and 130 are primarily processed by spot welding. For example, after the fixing pin 400 having the tapered end is inserted through the fixing pin holes 134 formed in the pair of mechanism frames 130 and 130 and the diaphragm 300, the welding is performed by spot welding.

Subsequently, the body 100 is rotated at one end of the fixing ring 110 in which the moving ring 120 in which the teeth group 121 is formed is rotatably fastened to the tool frames 130 and 130 fused by spot welding. It pivots coaxially, and this body 100 and the said tool frame 130,130 are secondary-processed by spot welding again as shown in FIG. 5B. For example, the body 100 formed on the pair of fixing rings is placed on the protrusions 133 formed on both sides of the pair of mechanism frames 130 and 130, and then fused using the spot welder 500.

Therefore, when the handcuff configured as described above is pushed against the criminal's wrist by the movement ring 120, the movement ring 120 rotates with the pivot as the support point. At this time, the teeth group 121 formed in the mobile ring 120 passes through the fixing ring 110 to cover the wrist of the criminal, and the teeth 201 formed on the step piece 200 in the fixing ring 110 again. When engaged, the spring 140 is moved to the locking groove formed at the outside of the body 100 by a pin formed at the back of the key of the handcuff, thereby the protrusion 210 of the step piece 200 and the protrusion 141 of the spring 140 are moved. Make contact.

As such, when the moving ring 120 is locked into the fixing ring 110, the present handcuffs are locked by locking the step piece 200 by the elastic force of the leaf spring 140, as well as the leaf spring 140 and the step piece. It is locked by the protrusions 141 and 210 formed in the 200, and the step piece 200 is rotated in the groove 131 formed in the mechanism frame 130, thereby preventing unauthorized release of the handcuffs.

At this time, when the criminal pushes the metal thin plate 10 or the like toward the moving ring entrance as shown in FIG. 3B, the metal thin plate 10 is no longer entered by the inclined protrusion 132. Is almost impossible.

In addition, even when a pin or the like is inserted through the key hole to release the step piece 200, the cuff is not released by the diaphragm 300 provided between the step piece 200 and the step piece 200.

As described above, even if the criminal attempts to release the handcuffs by using a pin or a thin metal sheet, it is impossible to release the inclined protrusion protruding from the framework.

In addition, a plurality of protrusions are formed on one side of the frame so as not to push the fixing pin formed on the body with a force such as a chisel or an auger from the outside as in the prior art, and a hole formed at a predetermined position of the frame After inserting the fixing pin with the tapered surface at both ends, the first spot welding, then covering the body to abut the plurality of protrusions formed on the fixing pin, and then welding the second spot, Unauthorized release can be prevented.

Therefore, there is an effect that it is impossible to release the handcuffs except the handcuffs key.
